MERGER PROPOSAL—YOUR VOTE IS VERY IMPORTANT


Dear stockholders of Equillium, Inc. and stockholders of Metacrine, Inc.:
As previously announced, the board of directors of Equillium, Inc., or Equillium, and the board of directors of Metacrine, Inc., or Metacrine, have approved an acquisition of Metacrine by Equillium. Equillium, Metacrine, Equillium Acquisition Sub, Inc., or Acquisition Sub I, Triumph Acquisition Sub, Inc., or Acquisition Sub II, and Triumph Merger Sub, Inc., or Merger Sub, entered into an Agreement and Plan of Merger, dated as of September 6, 2022, as amended on October 26, 2022, pursuant to which Merger Sub will merge with and into Metacrine, with Metacrine continuing as an indirect wholly owned subsidiary of Equillium, or the Merger.
If the transaction is completed, Metacrine stockholders will have the right to receive for each share of Metacrine common stock held by such stockholder (i) a portion of a share of Equillium common stock equal to the exchange ratio, or the Exchange Ratio, determined by dividing (x) (a) 125% of Metacrine’s net cash as of the closing of the Merger, or the Upfront Merger Consideration, by (b) the price per share of Equillium common stock determined based on the 10 day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the closing date of the Merger, provided that in no event will the price per share of Equillium common stock be less than $2.70 or greater than $4.50, or the Equillium Stock Price, by (y) the aggregate fully diluted shares of Metacrine, or Metacrine’s Closing Capitalization, plus (ii) any cash payable in lieu of fractional shares of Equillium’s common stock. The Exchange Ratio will not reflect changes in the market price of Metacrine common stock and will not reflect changes in the market price of Equillium common stock, except that the Exchange Ratio will reflect the 10-day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the closing date of the Merger, or the Closing Date.
For illustrative purposes only, we have provided the below assumptions and sensitivity analysis to inform your decision. Assuming (1) an Upfront Merger    Consideration of $33.75 million, which is based on Metacrine’s current forecasts of net cash as of December 23, 2022, the assumed closing date, or the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price of $2.70, which reflects the lowest trading price per share of Equillium common stock to be calculated for purposes of the Exchange Ratio, or the Floor Price, and the applicable per share price that would be used to determine the Exchange Ratio based on applying the 10-day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to November 8, 2022, the last trading day before November 9, 2022, and (3) Metacrine’s Closing Capitalization is 44,378,697, the aggregate fully diluted shares of Metacrine as of November 9, 2022, or the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.282.
Assuming (1) the Upfront Merger Consideration equals the Assumed Upfront Merger Consideration and (2) the Metacrine Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 increase to the Floor Price would decrease the Exchange Ratio to 0.258. Assuming (1) the Upfront Merger Consideration equals the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price of $4.50, which reflects the highest trading price per share of Equillium common stock to be calculated for purposes of the Exchange Ratio, or the Ceiling Price, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.169. Assuming (1) the Upfront Merger Consideration equals the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 decrease to the Ceiling Price would increase the Exchange Ratio to 0.179. Assuming (1) the Equillium Stock Price remains constant and (2) the Metacrine Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $1,000,000 increase or decrease in the Upfront Merger Consideration would increase or decrease, respectively, the Exchange Ratio by approximately 0.008.
We encourage you to obtain current market quotations of Equillium common stock and Metacrine common stock before voting.
Based on the Assumed Upfront Merger Consideration, Equillium estimates that it may issue between 7.5 and 12.5 million shares of its common stock to Metacrine equityholders in connection with the Closing. Upon completion of the Merger and based on the Assumed Upfront Merger Consideration and 34,352,084 shares of Equillium common stock outstanding as of November 9, 2022, we estimate that current Equillium stockholders will own between 82.08% and 73.32% of the outstanding common stock of the combined company and former Metacrine equityholders will own between 17.92% and 26.68% of the outstanding common stock of the combined company. If the actual facts are different from these assumptions (which they are likely to be), the percentage ownership retained by Equillium’s stockholders in the combined company will be different. The foregoing numbers are based on assumptions and illustrative and the actual percentage ownership in the combined company retained by Equillium’s stockholders at Closing will be calculated based on the actual numbers. Equillium common stock and Metacrine common stock are both traded on Nasdaq under the symbols “EQ” and “MTCR”, respectively. Upon completion of the Merger, Metacrine common stock will cease to be traded on Nasdaq.
At the special meeting of Equillium stockholders to be held virtually on December 20, 2022, Equillium stockholders will be asked to vote on (i) a proposal to approve the issuance of shares of Equillium common stock to Metacrine stockholders, which is a condition to completion of the Merger, or the Equillium stock issuance proposal, and (ii) a proposal to approve the adjournment from time to time of the Equillium virtual special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the issuance of shares of Equillium common stock in the Merger, which we refer to as the Equillium adjournment proposal.
At the special meeting of Metacrine stockholders to be held virtually on December 20, 2022, Metacrine stockholders will be asked to vote on (i) a proposal to adopt the Merger Agreement, or the Metacrine merger proposal and (ii) a proposal to approve the adjournment from time to time of the Metacrine virtual special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to adopt the Merger Agreement, or the Metacrine adjournment proposal.
Only holders of record of Equillium common stock on November 9, 2022 (including shares of Equillium common stock held through a bank, broker or other nominee that is a stockholder of record of Equillum) and holders of record of Metacrine common stock on November 9, 2022 (including shares of Metacrine common stock held through a bank, broker or other nominee that is a stockholder of record of Metacrine) are entitled to attend and vote at the virtual special meeting of Equillium stockholders or the virtual special meeting of Metacrine stockholders, respectively, or any adjournment or postponement thereof.
We cannot complete the Merger unless the Metacrine stockholders and the Equillium stockholders approve the respective proposals related to the Merger. Your vote is very important, regardless of the number of shares you own. Whether or not you expect to attend the Equillium virtual special meeting or Metacrine virtual special meeting, as applicable, please vote your shares as promptly as possible by (1) accessing the Internet website specified on your proxy card, (2) calling the toll-free number specified on your proxy card, or (3) signing and returning all proxy cards that you receive in the postage-paid envelope provided, so that your shares may be represented and voted at the Equillium or the Metacrine virtual special meeting, as applicable. If you are a Metacrine stockholder, please note that a failure to vote your shares is the equivalent of a vote against the Merger. If you are an Equillium stockholder, please note that a failure to vote your shares may result in a failure to establish a quorum for the Equillium virtual special meeting.
The Equillium board of directors, or the Equillium Board, recommends that Equillium stockholders vote “FOR” the Equillium stock issuance proposal and, if necessary, “FOR” the Equillium adjournment proposal. The Metacrine board of directors, or the Metacrine Board, recommends that Metacrine stockholders vote “FOR” the Metacrine merger proposal and, if necessary, “FOR” the Metacrine adjournment proposal.
The obligations of Equillium and Metacrine to complete the Merger are subject to the satisfaction or waiver of several conditions set forth in the Merger Agreement. More information about Equillium, Metacrine and the Merger is contained in this joint proxy statement/prospectus. Equillium and Metacrine encourage you to read this entire joint proxy statement/prospectus carefully, including the section entitled “Risk Factors” beginning on page 30.
We look forward to the successful Merger of Equillium and Metacrine.
Sincerely,
Sincerely,

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE VIRTUAL SPECIAL MEETINGS
The following are brief answers to certain questions that Equillium stockholders and Metacrine stockholders may have regarding the merger, the merger agreement, the issuance of shares of Equillium common stock in connection with the merger, the Equillium virtual special meeting, the Metacrine virtual special meeting, and other matters to be considered at the Equillium virtual special meeting and at the Metacrine virtual special meeting.

Q:
What is the proposed transaction?
A:
On September 6, 2022, Equillium, Metacrine, Acquisition Sub I, Acquisition Sub II, and Merger Sub, entered into the Merger Agreement. A copy of the Merger Agreement is attached to this joint proxy statement/prospectus as Annex A.
Under the terms of the Merger Agreement, Merger Sub will merge with and into Metacrine, with Metacrine continuing as an indirect, wholly owned subsidiary of Equillium, or the Merger. If the Merger is completed, holders of Metacrine common stock, or Metacrine stockholders, will have the right to receive for each share of Metacrine common stock held by such Metacrine stockholder (i) a portion of a share of Equillium common stock equal to the exchange ratio, or the Exchange Ratio, determined by dividing (x) (a) 125% of Metacrine’s net cash as of the closing of the Merger, or the Upfront Merger Consideration, by (b) the price per share of Equillium common stock determined based on the 10 day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the closing date of the Merger, provided that in no event will the price per share of Equillium common stock be less than $2.70 or greater than $4.50, or the Equillium Stock Price, by (y) the aggregate fully diluted shares of Metacrine, or Metacrine’s Closing Capitalization, plus (ii) any cash payable in lieu of fractional shares of Equillium’s common stock. The Exchange Ratio will not reflect changes in the market price of Metacrine common stock and will not reflect changes in the market price of Equillium common stock, except during the 10 trading days that are 10 trading days prior to the closing of the Merger. Holders of Equillium common stock, or Equillium stockholders, will not receive any merger consideration and will continue to hold their shares of Equillium common stock.
Q:
Why am I receiving this joint proxy statement/prospectus?
A:
In order to complete the Merger, among other things:
Equillium stockholders must vote to approve the issuance of shares of Equillium common stock to Metacrine stockholders in connection with the Merger, or the Equillium stock issuance proposal; and
Metacrine stockholders must vote to adopt the Merger Agreement, or the Metacrine merger proposal.
Equillium is holding a virtual special meeting of stockholders in order to obtain the stockholder approval necessary to approve the Equillium stock issuance proposal. Equillium stockholders will also be asked to approve the adjournment from time to time of the Equillium virtual special meeting if necessary to solicit additional proxies if there are not sufficient votes at the time of the Equillium virtual special meeting, or any adjournment or postponement thereof, to approve the stock issuance, or the Equillium adjournment proposal. It is important that Equillium stockholders vote on each of these matters, regardless of the number of shares owned.
Metacrine is holding a virtual special meeting of stockholders to obtain the stockholder approval necessary to approve the Metacrine merger proposal. In addition, Metacrine stockholders will also be asked to approve the adjournment from time to time of the Metacrine virtual special meeting if necessary to solicit additional proxies if there are not sufficient votes to approve the Metacrine merger proposal at the time of the Metacrine virtual special meeting or any adjournment or postponement thereof, or the Metacrine adjournment proposal. It is important that Metacrine stockholders vote their Metacrine common stock on each of these matters, regardless of the number of shares owned.
Your vote is important. We encourage you to vote as soon as possible.

Q:
What will Metacrine stockholders receive in the Merger?
A:
In connection with the closing of the Merger, Metacrine stockholders will have the right to receive for each share of Metacrine common stock held by such Metacrine stockholder (i) a portion of a share of Equillium common stock equal to the Exchange Ratio, plus (ii) any cash payable in lieu of fractional shares of Equillium’s common stock. The Exchange Ratio was devised so that Metacrine stockholders would, in the aggregate, receive a number of shares of Equillium common stock equal to 125% of Metacrine’s net cash at the closing of the Merger. The price of a share of Equillium common stock for purposes of determining the number of shares to be issued will be based on the 10 day trading volume weighted average calculated 10 trading days prior to the closing of the Merger. That price may be more or less than the current price or the price on the last trading day before public announcement of the Merger, but in no event will it be less than $2.70 per share or more than $4.50 per share. The Exchange Ratio will not reflect changes in the market price of Metacrine common stock and will not reflect changes in the market price of Equillium common stock, except during the 10 trading days that are 10 trading days prior to the closing of the Merger.
For illustrative purposes only, we have provided the below assumptions and sensitivity analysis to inform your decision. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price equal to the Floor Price, the applicable per share price that would be used to determine the Exchange Ratio based on applying the 10 day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to November 8, 2022, the last trading day before November 9, 2022, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.282.
Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to Metacrine’s Assumed Closing Capitalization, a $0.25 increase to the Floor Price would decrease the Exchange Ratio to 0.258. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price equal to the Ceiling Price, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.169. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 decrease to the Ceiling Price would increase the Exchange Ratio by 0.179. Assuming (1) the Equillium Stock Price remains constant and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $1,000,000 increase or decrease in the Upfront Merger Consideration would increase or decrease, respectively, the Exchange Ratio by approximately 0.008.
We encourage you to obtain current market quotations of Equillium common stock and Metacrine common stock before voting.

Q:
After applying the Exchange Ratio, how will fractional shares be handled?
A:
No certificate or scrip representing fractional shares of Equillium common stock will be issued in connection with the Merger, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of an Equillium stockholder. AST, acting as agent for the holders of Metacrine common stock otherwise entitled to receive fractional shares of Equillium common stock at the Closing, will aggregate all fractional shares of Equillium common stock that would otherwise have been required to be distributed and cause them to be sold in the open market for the accounts of such holders. Each holder of Metacrine common stock who would otherwise have been entitled to receive a fraction of a share of Equillium common stock will receive cash, rounded to the nearest whole cent and without interest, in an amount equal to the proceeds from such sale by AST, if any, less applicable fees and expenses, including broker fees.
Q:
How does the Exchange Ratio affect the ownership of Equillium after completion of the Merger?
A:
The Exchange Ratio will determine the relative ownership percentages of the current Equillium stockholders and the current Metacrine stockholders in the combined company. The Exchange Ratio will not be definitively determined until shortly prior to the closing of the Merger.

Q:
What vote is required to approve each proposal at the Equillium virtual special meeting?

Failure to vote virtually or by proxy at the special meeting, abstentions, and broker non-votes (if any) will have no effect on the outcome of the Equillium stock issuance proposal.

Approval of the Equillium adjournment proposal requires the affirmative vote of the holders of Equillium common stock representing a majority of the votes cast at the Equillium virtual special meeting (whether or not a quorum is present). Failure to vote virtually or by proxy at the special meeting, abstentions, and broker non-votes (if any) will have no effect on the outcome of the Equillium adjournment proposal. Shares of Equillium common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon.
Q:
What vote is required to approve each proposal at the Metacrine virtual special meeting?
A:
Metacrine Merger Proposal. Approval of the Metacrine merger proposal requires the affirmative vote of a majority of the outstanding shares of Metacrine’s common stock. Failure to vote virtually or by proxy at the special meeting, abstentions, and broker non-votes (if any) will have the same effect as a vote against the Metacrine merger proposal. Shares of Metacrine common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon.
Metacrine Adjournment Proposal. Approval of the Metacrine adjournment proposal requires the affirmative vote of the holders of Metacrine common stock representing a majority of the votes cast at the Equillium virtual special meeting (whether or not a quorum is present). Failure to vote virtually or by proxy at the special meeting, abstentions, and broker non-votes (if any) will have no effect on the outcome of the Metacrine adjournment proposal.

Pursuant to an action by unanimous written consent of the Metacrine Board dated September 5, 2022, the Metacrine Board determined that the Merger Agreement and the transactions contemplated thereby were in the best interests of Metacrine and its stockholders, and approved the Merger Agreement and the Merger, the execution of the Merger Agreement and the consummation of the transactions contemplated thereby and declared advisable and recommended that Metacrine’s stockholders adopt the Merger Agreement. The Metacrine Board recommends that Metacrine stockholders vote “FOR” the Metacrine merger proposal and “FOR” the Metacrine adjournment proposal.
Q:
How does the Equillium Board recommend that Equillium stockholders vote?
A:
At a meeting of the Equillium Board held on September 5, 2022, the Equillium Board determined that the Merger Agreement and the transactions contemplated thereby, including the issuance of shares of Equillium common stock to the Metacrine stockholders in connection with the Merger, were in the best interests of
5

TABLE OF CONTENTS

Equillium and its stockholders, and approved the Merger Agreement and the Merger, the execution of the Merger Agreement and the consummation of the transactions contemplated thereby. The Equillium Board recommends that Equillium stockholders vote “FOR” the Equillium stock issuance proposal and “FOR” Equillium adjournment proposal.
Q:
How many votes do I have?
A:
Equillium. You are entitled to one vote for each share of Equillium common stock that you owned as of the Equillium record date. As of the close of business on November 9, 2022, there were 34,352,084 outstanding shares of Equillium common stock. As of that date, 25.5% of the outstanding shares of Equillium common stock were beneficially owned by the directors and executive officers of Equillium.
Metacrine. You are entitled to one vote for each share of Metacrine common stock that you owned as of the Metacrine record date. As of the close of business on November 9, 2022, there were 42,569,515 outstanding shares of Metacrine common stock. As of that date, 8.4% of the outstanding shares of Metacrine common stock were beneficially owned by the directors and executive officers of Metacrine.
Q:
What will happen if I fail to vote or I abstain from voting?
A:
Equillium. If you are an Equillium stockholder, abstentions and broker “non-votes” have no effect on the outcome of the Equillium stock issuance proposal or the Equillium adjournment proposal. Shares of Equillium common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon.
Your failure to cast a vote virtually will also make it more difficult to meet the quorum requirement with respect to the Equillium stock issuance proposal.
Metacrine. If you are a Metacrine stockholder, failure to vote virtually or by proxy at the Metacrine virtual special meeting, abstentions, and broker non-votes (if any) will have the same effect as a vote against the Metacrine merger proposal. Shares of Metacrine common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon.
Q:
What are “broker non-votes”?
A:
Brokers who hold shares in street name for customers have the authority to vote on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are precluded from exercising their voting discretion with respect to approval of non-routine matters, such as the Equillium stock issuance proposal and the Metacrine merger proposal, and, as a result, absent specific instructions from the beneficial owner of such shares, brokers are not empowered to vote those shares, referred to generally as “broker non-votes.” Broker non-votes, if any, will be treated as shares that are present at the virtual special meeting for purposes of determining whether a quorum exists but will not be counted or deemed present virtually or by proxy for the purpose of voting on the Equillium stock issuance proposal or the Metacrine merger proposal. Broker non-votes, if any, will have the same effect as a vote against the Metacrine merger proposal.
Q:
What constitutes a quorum?
A:
Equillium. The holders of a majority of the voting power of Equillium’s outstanding shares of common stock entitled to vote as of the close of business on the Equillium record date must be virtually present or represented by proxy to constitute a quorum to conduct the Equillium virtual special meeting. All shares of Equillium common stock represented at the Equillium virtual special meeting, including abstentions and broker non-votes, will be treated as present for purposes of determining the presence or absence of a quorum to conduct the Equillium virtual special meeting.
Metacrine. The holders of a majority of the voting power of Metacrine’s outstanding shares of common stock entitled to vote as of the close of business on the Metacrine record date must be virtually present or represented by proxy to constitute a quorum to conduct the Metacrine virtual special meeting. All shares of Metacrine common stock represented at the Metacrine virtual special meeting, including abstentions and broker non-votes will be treated as present for purposes of determining the presence or absence of a quorum to conduct the Metacrine virtual special meeting.

TABLE OF CONTENTS

Q:
What is the difference between a stockholder of record and a “street name” holder?
A:
If your shares are registered directly in your name, you are considered the stockholder of record with respect to those shares. If your shares are held in a stock brokerage account or by a bank, trust company or other nominee, then the broker, bank, trust company or other nominee is considered to be the stockholder of record with respect to those shares, while you are considered the beneficial owner of those shares. In the latter case, your shares are said to be held in “street name.”
Q:
If I am a beneficial owner of shares held in street name, how do I vote?
A:
If you are not a stockholder of record but instead hold your shares in a stock brokerage account, or if your shares are held by a bank, trust company or other nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. If you are an Equillium stockholder but not a stockholder of record and you do not instruct your broker on how to vote your shares, your broker may not vote your shares on the Equillium stock issuance proposal or any adjournment proposal, which will have no effect on the vote on this proposal, assuming a quorum is present. If you are a Metacrine stockholder but not a stockholder of record and you do not instruct your broker on how to vote your shares, your broker may not vote your shares, which will have the same effect as a vote against the Metacrine merger proposal and, assuming a quorum is present, will have no effect on the outcome of the Metacrine adjournment proposal.
Please follow the voting instructions provided by your broker or nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to Equillium or Metacrine or by voting virtually at your special meeting. Further, brokers who hold shares of Equillium common stock or Metacrine common stock on behalf of their customers may not give a proxy to Equillium or Metacrine to vote those shares without specific instructions from their customers.
Q:
What will happen if I return my proxy card without indicating how to vote?
A:
If you are an Equillium stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Equillium common stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the Equillium virtual special meeting and will be voted “FOR” that proposal.
If you are a Metacrine stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Metacrine common stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the Metacrine virtual special meeting and will be voted “FOR” that proposal.
Q:
Can I change my vote after I have returned a proxy or voting instruction card?
A:
Yes. You can change your vote at any time before your proxy is voted at the Equillium virtual special meeting or the Metacrine virtual special meeting, as applicable. You can do this in one of four ways:
you can send a signed notice of revocation;
you can grant a new, valid proxy bearing a later date;
you can vote again by telephone or the Internet at a later time; or
if you are a holder of record, by voting at the Equillium virtual special meeting or Metacrine virtual special meeting, as applicable, which will automatically cancel any proxy previously given, or you may revoke your proxy by attending such virtual special meeting, but your attendance alone will not revoke any proxy that you have previously given.
If you choose either of the first two methods, you must provide your notice of revocation or your new proxy to the Secretary of Equillium or Secretary of Metacrine, as applicable, prior to your shares being voted. If your shares are held in street name by your broker or nominee, you should contact them to change your vote.
Q:
What should I do if I receive more than one set of voting materials?
A:
Please vote each proxy card and voting instruction card that you receive. You may receive more than one set of voting materials, including multiple copies of this joint proxy statement/prospectus and multiple proxy

cards or voting instruction cards. For example, stockholders who hold shares in more than one brokerage account will receive a separate voting instruction card for each brokerage account in which shares are held. If shares are held in more than one name, stockholders will receive more than one proxy or voting instruction card. In addition, if you are a stockholder of both Equillium and Metacrine, you may receive one or more proxy cards or voting instruction cards for Equillium and one or more proxy cards or voting instruction cards for Metacrine. If you are a stockholder of both Equillium and Metacrine, please note that a vote for the issuance of shares of Equillium common stock in the Merger pursuant to the terms of the Merger Agreement for the Equillium virtual special meeting will not constitute a vote for the proposal to adopt the Merger Agreement for the Metacrine virtual special meeting, and vice versa. Therefore, please vote each proxy and voting instruction card you receive, whether from Equillium or Metacrine.
Q:
Is there a list of stockholders entitled to vote at the Equillium and Metacrine virtual special meetings?
A:
The names of stockholders of record entitled to vote at the Equillium virtual special meeting will be available at the Equillium virtual special meeting and for 10 days prior to the Equillium virtual special meeting for any purpose germane to the special meeting, between the hours of 9:00 a.m. and 4:30 p.m. (Pacific Time), at Equillium’s principal executive offices located at 2223 Avenida de la Playa, Suite 105, La Jolla, California 92037, or by contacting Equillium’s corporate secretary.

Q:
What happens if I am a Metacrine stockholder who sells my shares of Metacrine common stock before the Metacrine virtual special meeting?
A:
The record date for the Metacrine virtual special meeting is earlier than the Metacrine virtual special meeting. If you transfer your shares of Metacrine common stock after the Metacrine record date but before the Metacrine virtual special meeting, you will retain your right to vote at the Metacrine virtual special meeting, but will have transferred the right to receive the merger consideration in the Merger. In order to receive the merger consideration, you must hold your shares through the effective time of the Merger.

Q:
What will happen to my Metacrine stock options, restricted stock units and/or warrants at the time of the Merger?
A:
Treatment of Restricted Stock Unit Awards. At the effective time of the Merger, each Metacrine restricted stock unit outstanding immediately prior to such time, or a Metacrine RSU, whether vested or unvested, other than Metacrine RSUs held by any former employee, former service provider or director of Metacrine, will be assumed by Equillium and converted into a restricted stock unit for a number of shares of Equillium common stock, or an assumed RSU, equal to the product of (a) the number of shares of Metacrine common stock subject to such Metacrine RSU and (b) the Exchange Ratio (with any fractional shares rounded down to the nearest whole share). Except for the change to the number and type of shares, each assumed RSU will be subject to the same terms and conditions, including vesting, as were applicable to such Metacrine RSU prior to the Merger. At the effective time of the Merger, (a) each outstanding unvested Metacrine RSU held by a former employee, former service provider or director of Metacrine will be cancelled without the payment of any consideration and (b) each outstanding vested and unexercised Metacrine RSU held by a former employee, former service provider or director of Metacrine will be cancelled and converted into a

At the effective time of the Merger, each option to purchase Metacrine common stock that is outstanding and unexercised immediately prior to such time, or a Metacrine option, whether vested or unvested, other than any Metacrine option held by any former employee, former service provider or director of Metacrine, will be assumed by Equillium and converted into an option to acquire a number of shares of Equillium common stock, or an adjusted option, equal to the product of (a) the number of shares of Metacrine common stock subject to such Metacrine option and (b) the Exchange Ratio (rounded down to the nearest whole share). The per share exercise price of each adjusted option will be equal to (i) the per share exercise price of such Metacrine option immediately prior to the Merger divided by (ii) the Exchange Ratio (with the resulting price per share rounded up to the nearest whole cent). Except for the changes made to the number and type of shares and the exercise price, each adjusted option will be subject to the same terms and conditions, including vesting, as were applicable to such Metacrine option immediately prior to the Merger. At the effective time of the Merger, each unvested Metacrine option that is outstanding and unexercised as of immediately prior to such time and held by a former employee, former service provider or director of Metacrine will be cancelled without the payment of any consideration, and each vested Metacrine option that is outstanding and unexercised as of immediately prior to such time and held by a former employee, former service provider or director of Metacrine will be cancelled and converted into a right to receive a number of shares of Equillium common stock equal to the product of (x) the number of shares of Metacrine common stock subject to such Metacrine option multiplied by the excess, if any, of (1) the 10 day volume weighted average closing sale price of one share of Metacrine common stock for the 10 trading days prior to the effective time of the Merger (as adjusted as appropriate to reflect any stock splits, stock dividends, combinations, mergers, reorganizations, reclassifications or similar events), or the Metacrine Share Value over (2) the per share exercise price for shares subject to such Metacrine option, divided by (y) the Metacrine Share Value, multiplied by (z) the Exchange Ratio (rounded down to the nearest whole share).
Treatment of Warrants. At the effective time of the Merger, each of Metacrine’s warrants, or Metacrine Warrant, that is outstanding and unexercised immediately prior to the closing of the Merger will be automatically substituted into a warrant to purchase the number of shares of Equillium common stock equal to the product obtained by multiplying (i) the number of shares of Metacrine common stock subject to the Metacrine Warrant immediately prior to the closing of the Merger by (ii) the Exchange Ratio (rounding up to the nearest whole share). Each Metacrine Warrant will have an exercise price per share of Equillium common stock equal to (i) the exercise price per share provided in the Metacrine Warrant immediately prior to the closing of the Merger divided by (ii) the Exchange Ratio.
Treatment of ESPP. Following the date of the Merger Agreement, Metacrine has taken actions with respect to Metacrine’s 2020 Employee Stock Purchase Plan, or the ESPP, to provide that with respect to any offering periods in effect as of the date of the Merger Agreement, or the current purchase period, (i) no employee who is not a participant in the ESPP as of the date of the Merger Agreement may become a participant in the ESPP, and (ii) no employee participating in the current purchase period may increase his or her payroll contribution rate pursuant to the ESPP from the rate in effect immediately prior to the date of the Merger Agreement, except as required by applicable law. In addition, (A) the current purchase period will end on a specified trading day occurring at least 10 days prior to the date on which the Merger is expected to close; (B) there will be no offering periods following the current purchase period and (C) in all events, Metacrine shall terminate the ESPP prior to the effective time of the Merger.
Q:
How will the rights of Metacrine stockholders change after the Merger?
A:
Metacrine stockholders will receive shares of Equillium common stock in connection with the Merger and will no longer be stockholders of Metacrine following the Merger. Their rights as holders of Equillium common stock will be governed by the amended and restated certificate of incorporation of Equillium and Equillium’s amended and restated bylaws.

Q:
What are the material U.S. federal income tax consequences of the Merger to U.S. holders of Metacrine common stock?
A:
For U.S. federal income tax purposes, the receipt of the merger consideration by a U.S. Holder (as defined in the section captioned “Material U.S. Federal Income Tax Consequences of the Merger” in exchange for such U.S. Holder’s shares of our common stock in the merger is generally expected to be a taxable transaction for U.S. federal income tax purposes. In that case, such exchange will result in the recognition of gain or loss in an amount measured by the difference, if any, between the fair market value of the merger consideration that such U.S. Holder receives in the merger and such U.S. Holder’s adjusted tax basis in the shares of our common stock surrendered in the merger.
A Non-U.S. Holder (as defined in the section captioned “Material U.S. Federal Income Tax Consequences of the Merger”) generally will not be subject to U.S. federal income tax with respect to the exchange of our common stock for the Merger Consideration in the Merger unless such Non-U.S. Holder has certain connections to the United States, but may be subject to backup withholding tax unless the Non-U.S. Holder complies with certain certification procedures or otherwise establishes a valid exemption from backup withholding tax.

Parties to the Merger
Equillium, Inc.
2223 Avenida de la Playa, Suite 105
La Jolla, California 92037
(858) 240-1200
Equillium was incorporated in the state of Delaware on March 16, 2017. Equillium is a clinical-stage biotechnology company leveraging deep understanding of immunology to develop novel products to treat severe autoimmune and inflammatory disorders with high unmet medical need. Equillium’s strategy is focused on advancing the clinical development of its product candidates, including potentially pursuing additional indications and acquiring new product candidates and platforms to expand its pipeline. Equillium intends to commercialize its product candidates either independently or through partnerships or otherwise monetize its pipeline through strategic transactions.
Since inception, Equillium has devoted substantially all of its efforts to organizing and staffing the company, business planning, raising capital, in-licensing rights to itolizumab (EQ001), conducting non-clinical research, filing three Investigational New Drug applications, conducting pre-clinical and clinical development of Equillium’s initial product candidate, itolizumab (EQ001), conducting business development activities such as the acquisition of Bioniz Therapeutics, Inc., in February 2022, preparing to initiate clinical studies of EQ101 and EQ102, and the general and administrative activities associated with operating a public company. Equillium has not generated revenues from its principal operations, and the sales and income potential of its business is unproven.
About Itolizumab
Itolizumab (EQ001) is a clinical-stage, first-in-class anti-CD6 monoclonal antibody that selectively targets the CD6-ALCAM pathway. This pathway plays a central role in modulating the activity and trafficking of T cells that drive a number of immuno-inflammatory diseases. Equillium acquired rights to itolizumab through an exclusive partnership with Biocon Limited.
About Equillium’s Multi-Cytokine Platform and Product Candidates EQ101 and EQ102
Equillium’s proprietary multi-cytokine platform, or MCP, generates rationally designed composite peptides that selectively block key cytokines at the shared receptor level targeting pathogenic cytokine redundancies and synergies while preserving non-pathogenic signaling. This approach provides multi-cytokine inhibition at the receptor level and is expected to avoid the broad immuno-suppression and off-target safety liabilities that may be associated with other therapeutic classes, such as JAK inhibitors. Many immune-mediated diseases are driven by the same combination of dysregulated cytokines, and Equillium believes identifying the key cytokines for these diseases will allow it to target and develop customized treatment strategies for multiple autoimmune and inflammatory diseases. Current MCP assets include EQ101, a first-in-class, tri-specific inhibitor of IL-2, IL-9 and IL-15, and EQ102, a first-in-class, selective inhibitor of IL-15 and IL-21.
This joint proxy statement/prospectus incorporates important business and financial information about Equillium from other documents that are not included in or delivered with this joint proxy statement/prospectus.

TABLE OF CONTENTS

Regulatory Matters
Neither Equillium nor Metacrine is aware of any material regulatory approvals or actions that are required for completion of the Merger. It is presently contemplated that if any such additional regulatory approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.
Accounting Treatment (See page 122)
Equillium prepares its consolidated financial statements in accordance with accounting principles generally accepted in the United States, or GAAP. The Merger will be accounted for using the acquisition method of accounting, with Equillium treated as the acquiror. Please see the section entitled “The Merger—Accounting Treatment” on page 122 of this joint proxy statement/prospectus.
Appraisal Rights (See page 122)
Under Delaware law, the Metacrine stockholders are not entitled to appraisal rights in connection with the Merger or any other transaction contemplated by the Merger Agreement.
Under Delaware law, the Equillium stockholders are not entitled to appraisal rights in connection with the issuance of shares of Equillium common stock in the Merger pursuant to the terms of the Merger Agreement.
Metacrine’s Executive Officers and Directors Have Financial Interests in the Merger That Differ from the Interests of Metacrine Stockholders (See page 118)
Certain members of the Metacrine Board and certain executive officers of Metacrine may be deemed to have financial interests in the Merger that are in addition to, or different from, the interests of other Metacrine stockholders generally. The Metacrine Board was aware of these interests and considered them, among other matters, in approving the Merger and the Merger Agreement and in making the recommendation that Metacrine stockholders adopt the Merger Agreement. These potential interests include:
Accelerated vesting of equity awards upon the Effective Time of the Merger and upon certain terminations of employment or service following the Effective Time of the Merger;
Following the Effective Time, it is expected that Dr. Klassen will be appointed to the Equillium Board;
Cash severance and other benefits upon certain terminations of employment or service following the Effective Time of the Merger; and
Indemnification by the combined company for liabilities for acts or omissions occurring at or prior to the Effective Time of the Merger.
For additional details about these interests, see “Financial Interests of Metacrine Directors and Executive Officers in the Merger” beginning on page 118 of this joint proxy statement/prospectus.
Rights of Metacrine Stockholders Will Change as a Result of the Merger (See page 130)
As a result of the Merger, Metacrine stockholders will become holders of shares of Equillium common stock, and their rights will be governed by the Amended and Restated Certificate of Incorporation of Equillium and Equillium’s Amended and Restated Bylaws (instead of the Amended and Restated Certificate of Incorporation of Metacrine and Metacrine’s Amended and Restated Bylaws) and the General Corporation Law of Delaware, or the DGCL. Following the Merger, former Metacrine stockholders will have different rights as holders of Equillium common stock than they had as Metacrine stockholders due to differences in the organizational documents of Equillium and Metacrine. For additional information on stockholder rights, see “Description of Capital Stock and Comparison of Rights of Equillium Stockholders and Metacrine Stockholders” beginning on page 130 of this joint proxy statement/prospectus.

TABLE OF CONTENTS

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
The following unaudited pro forma condensed combined financial information is presented to illustrate the estimated effects of the proposed Merger.
The unaudited pro forma condensed combined balance sheet information as of June 30, 2022 is based upon and derived from the historical financial information of Equillium and Metacrine and gives effect to the Merger as if such acquisition had occurred on June 30, 2022. The unaudited pro forma condensed combined statements of operations and comprehensive loss for the year ended December 31, 2021 and the six months ended June 30, 2022 are also based upon and derived from the historical financial information of Equillium and Metacrine and give effect to the Merger as if it occurred on January 1, 2021. In addition, the unaudited pro forma condensed combined statements of operations and comprehensive loss for the year ended December 31, 2021 and the six months ended June 30, 2022 are also based upon and derived from the historical financial information of Bioniz, Inc., or Bioniz, which was acquired by Equillium on February 14, 2022 and give effect to the Bioniz acquisition as if it occurred on January 1, 2021, or the Bioniz Acquisition and together with the Merger, the Acquisitions.
The unaudited pro forma condensed combined financial information should be read in conjunction with:
Equillium’s audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2021, as contained in its Annual Report on Form 10-K filed on March 23, 2022 with the SEC.
Equillium’s unaudited condensed consolidated financial statements and accompanying notes as of and for the six months period ended June 30, 2022, as contained in its Quarterly Report on Form 10-Q filed on August 15, 2022 with the SEC.
Metacrine’s audited consolidated financial statements and accompanying notes as of and for the year ended December 31, 2021, as contained in its Annual Report on Form 10-K filed on March 30, 2022 with SEC.
Metacrine’s unaudited condensed consolidated financial statements and accompanying notes as of and for the six months period ended June 30, 2022, as contained in its Quarterly Report on Form 10-Q filed on August 9, 2022 with the SEC.
The other information contained in or incorporated by reference into this filing.
Additional information about the basis of presentation of this information is provided in Note 1 hereto.
The unaudited pro forma condensed combined financial information is provided for informational purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the Acquisitions had been completed as of the dates set forth above, nor is it indicative of the future results or financial position of the combined company. In connection with the pro forma financial information, Equillium allocated the purchase price using its best estimates of fair value. Accordingly, the pro forma Merger price adjustments are preliminary and subject to further adjustments as additional information becomes available and as additional analyses are performed. The unaudited pro forma condensed combined financial information also does not give effect to the potential impact of current financial conditions, any anticipated synergies, operating efficiencies or cost savings that may result from the Merger or any integration costs. The unaudited pro forma condensed combined statements of operations and comprehensive loss do not reflect certain amounts resulting from the Merger that were determined to be of a non-recurring nature.
The unaudited pro forma condensed combined financial information was prepared in accordance with Article 11 of Regulation S-X. Equillium has accounted for the Merger using the acquisition method of accounting, in accordance with FASB Accounting Standards Codification, or ASC, Topic 805 “Business Combinations”, or ASC 805. Equillium preliminarily determined that the Merger constitutes an acquisition of assets instead of a business combination as substantially all of the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets, and therefore, the Merger was not considered a business combination.
After the closing of the Merger, Equillium will complete the valuations necessary to finalize the required purchase price allocation based upon the fair market values as of the actual closing date of the Merger, at which time the final allocation of the purchase price will be determined. The pro forma financial information contained in this joint proxy statement/prospectus is also based upon certain assumptions with respect to the amount of net

cash to be received from Metacrine at the closing of the Merger and the number of shares of Equillium common stock to be issued to Metacrine at closing of the Merger. Differences between preliminary estimates in the pro forma financial information presented herein and the final acquisition accounting will occur and could have a material impact on the pro forma financial information. In this regard, differences between those preliminary estimates and the actual net cash received from Metacrine at the closing of the Merger and the number of shares of Equillium common stock ultimately issued to Metacrine at closing of the Merger would result in changes to various components of the unaudited pro forma condensed combined balance sheet, including cash and cash equivalents, common stock and additional paid-in capital, and various components of the unaudited pro forma condensed combined statements of operations, including in-process research and development expense, net loss per share and weighted-average shares used in computing net loss per share.
The unaudited pro forma condensed combined financial information has been prepared by Equillium in accordance with SEC Regulation S-X Article 11 and is not necessarily indicative of the condensed combined financial position or results of operations that would have been realized had the Acquisitions been completed as of the dates indicated above, nor is it meant to be indicative of any anticipated combined financial position or future results of operations that Equillium will experience after the Merger is completed. In addition, the accompanying unaudited pro forma condensed combined statements of operations and comprehensive loss do not include any pro forma adjustments to reflect expected cost savings or restructuring actions which may be achievable or the impact of any non-recurring expenses and one-time transaction-related costs that may be incurred as a result of the Acquisitions.
Description of the Merger
Equillium, Metacrine, Acquisition Sub I, Acquisition Sub II and Merger Sub entered into the Merger Agreement dated September 6, 2022 and amended on October 26, 2022. Pursuant to the Merger Agreement, Merger Sub will be merged with and into Metacrine, and Metacrine will continue as the surviving corporation and an indirect, wholly owned subsidiary of Equillium. In connection with the Merger, all of the issued and outstanding shares of common stock of Metacrine, par value $0.0001 per share, or the Shares, will be cancelled and converted into the right to receive consideration per share consisting of (i) the Exchange Ratio, which is determined by dividing (x) (a) 125% of Metacrine’s net cash as of the closing of the Merger, or the Closing, by (b) the price per share of common stock of Equillium, par value $0.0001 per share, or Equillium common stock determined based on the 10-day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the Closing date, provided that the price per share of Equillium common stock shall be no less than $2.70 and no more than $4.50 by (y) the aggregate fully diluted shares of Metacrine, plus (ii) any cash payable in lieu of fractional shares of Equillium’s common stock. As defined in the Merger Agreement, net cash consists of Metacrine’s cash and cash equivalents, deposits, prepaid expenses, and short-term investments, adjusted by certain factors including the full payoff amount of Metacrine’s existing term debt having an outstanding principal of $15 million. Net cash is estimated to be approximately $27.0 million at Closing, assuming a Closing on December 23, 2022. In addition, Equillium has agreed to terms on an amended debt facility with Metacrine’s current lender, K2 HealthVentures LLC, whereby at the Closing Equillium would assume Metacrine’s existing loan, subject to certain modifications. Concurrent with the Closing, Equillium intends to retire its existing debt facility with Oxford Finance LLC and SVB, which has an outstanding principal balance of $10 million as of June 30, 2022.
Consummation of the Merger is subject to certain closing conditions, including Metacrine’s net cash being no less than $23 million, the absence of certain legal impediments, the effectiveness of a registration statement to which this joint proxy statement/prospectus is a part, adoption of the Merger Agreement by the holders of a majority of Metacrine’s outstanding common stock at Metacrine’s virtual special meeting, and approval of the issuance of shares of Equillium common stock in the Merger by the holders of shares of Equillium common stock representing a majority of the votes cast at Equillium’s virtual special meeting.

TABLE OF CONTENTS

1. Basis of presentation
The historical consolidated financial information of Equillium has been adjusted in the accompanying unaudited pro forma condensed combined financial information to give effect to pro forma events that are (i) directly attributable to the Acquisitions, (ii) factually supportable, and (iii) with respect to the unaudited pro forma condensed combined statements of operations and comprehensive loss, are expected to have a continuing impact on the results of operations.
The unaudited pro forma condensed combined financial statements were prepared in accordance with the regulations of the SEC and are intended to show how the Acquisitions might have affected the historical financial statements. The unaudited pro forma condensed combined financial information set forth herein is based upon the consolidated financial statements of Equillium, Bioniz and Metacrine. The unaudited pro forma condensed combined financial information is presented as if the Merger had been completed on June 30, 2022 with respect to the unaudited pro forma condensed combined balance sheet as of June 30, 2022 and as of January 1, 2021 with respect to the unaudited pro forma condensed combined statements of operations and comprehensive loss for the year ended December 31, 2021 and the six month period ended June 30, 2022 for both the Acquisitions. The unaudited pro forma condensed combined financial statements have also been adjusted to give effect to pro forma events that are directly attributable to the Acquisitions, factually supportable and expected to have a continuing impact on the combined results.
Equillium’s combined financial information has been prepared in accordance with Generally Accepted Accounting Principles in the United States, or GAAP, as issued by the Financial Accounting Standards Board, or FASB. Metacrine’s and Bioniz’s financial information has been historically prepared in accordance with GAAP.
The unaudited pro forma condensed combined financial information is presented for informational purposes only and is not necessarily indicative of the combined financial position or results of operations had the Merger occurred as of the dates indicated, nor is it meant to be indicative of any anticipated combined financial position or future results of operations that the combined company will experience after the completion of the Merger. To the extent there are significant changes to the combined company’s business following completion of the Merger, the assumptions and estimates set forth in the unaudited pro forma condensed combined financial statements could change significantly.
Equillium determined the Merger constitutes an acquisition of assets instead of a business combination as substantially all of the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets, and therefore, the acquisition was not considered a business. Asset acquisitions are accounted for by allocating the cost of the acquisition, including transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis without recognition of goodwill.
Equillium determined the Merger meets the definition of an acquisition of a business as defined in Rule 8-04 of Regulation S-X of the SEC. The accompanying unaudited pro forma condensed combined financial information was prepared for the purpose of complying with Rule 8-04 of Regulation S-X of the SEC and for inclusion in Equillium’s filings with the SEC.
2. Accounting Policies
Following the execution of the Merger Agreement, Equillium will conduct a review of accounting policies of Metacrine in an effort to determine if differences in accounting policies require restatement or reclassification of results of operations or reclassification of assets or liabilities to conform to Equillium’s accounting policies and classifications. Equillium may identify differences among the accounting policies of Equillium and Metacrine that, when conformed, could have a material impact on this unaudited pro forma condensed combined financial information. During the preparation of this unaudited pro forma condensed combined financial information, Equillium was not aware of any material differences between accounting policies of Equillium and Metacrine to conform to Equillium’s financial presentation, and accordingly, this unaudited pro forma condensed combined financial information does not assume any material differences in accounting policies among Equillium and Metacrine.

3. Consideration Transferred
The calculation of the estimated preliminary purchase consideration is as follows:
Estimated equity consideration
In connection with the Merger, all of the issued and outstanding Shares will be cancelled and converted into the right to receive consideration per share consisting of (i) the Exchange Ratio, plus (ii) any cash payable in lieu of fractional shares of Equillium’s common stock.
Each of Metacrine’s stock options, or Options, that is outstanding as of immediately prior to the effectiveness of the Merger, or the Effective Time, will (i), if held by a continuing employee or service provider, be substituted automatically into an Equillium option award to purchase the number of shares of Equillium common stock equal to the number of Shares subject to the Option immediately prior to the Effective Time multiplied by the Exchange Ratio, and (ii) if the Option is held by a former employee, service provider or director of Metacrine, (x) to the extent unvested, be cancelled without the payment of any consideration and (y) to the extent vested, be cancelled and converted into a right to receive the number of shares of Equillium common stock equal to (1) the number of Shares subject to the Option immediately prior to the Effective time multiplied by the excess, if any, of Metacrine’s price per Share based on the 10 day trading volume weighted average price per Share calculated 10 trading days prior to the Closing date over the per share exercise price for the Shares underlying the Option immediately prior to the Effective Time, or the Metacrine Share Value, divided by (2) the Metacrine Share Value multiplied by the Exchange Ratio.
Each of Metacrine’s restricted stock unit awards, or the RSUs, that is outstanding as of immediately prior to the Effective Time will (i), if held by a continuing employee or service provider, whether vested or unvested, be substituted automatically into an Equillium restricted stock unit award with respect to a number of shares of Equillium common stock equal to the product obtained by multiplying the total number of Shares subject to the RSU immediately prior to the Effective Time by the Exchange Ratio, and (ii) if the RSU is held by a former employee, service provider or director of Metacrine, (x) to the extent unvested, be cancelled without the payment of any consideration and (y) to the extent vested, be cancelled and converted into a right to receive the number of shares of Equillium common stock equal to the product obtained by multiplying the total number of Shares subject to the RSU immediately prior to the Effective Time by the Exchange Ratio.
Each of Metacrine’s warrants, or the Warrants, that is outstanding and unexercised immediately prior to the Effective Time will be automatically substituted into a warrant to purchase the number of shares of Equillium common stock equal to the product obtained by multiplying the number of Shares subject to the Warrant immediately prior to the Effective Time by the Exchange Ratio. Each Warrant will have an exercise price per share of Equillium common stock equal to exercise price per Share immediately prior to the Effective Time divided by the Exchange Ratio.
Estimated number of shares of the combined company to be owned by Metacrine stockholders
12,350,633
Multiplied by the assumed price per share of Equillium common stock(1)
$2.70
Estimated equity consideration
$33,346,709
(1)
Represents the floor price of the collar as Equillium’s stock price was trading below the floor as of November 8, 2022. The number of Equillium shares actually issued at closing will be based on the actual 10-day volume weighted average closing price of Equillium common stock calculated 10 trading days preceding the closing.
For illustrative purposes only, we have calculated the potential number of shares Equillium would issue in connection with the closing of the Merger based on the assumptions and sensitivity analysis set forth herein.
Based on (1) the Estimated equity consideration of $33,346,709, or the Pro Forma Assumed Upfront Merger Consideration, and (2) an Equillium Stock Price equal to the Floor Price, Equillium would issue 12,350,633 shares of common stock.
Keeping the Pro Forma Assumed Upfront Merger Consideration constant, a $0.25 increase from the Floor Price would decrease the number of shares of common stock Equillium issues at the Closing by 1,046,664. Keeping the Equillium stock price constant, a $1 million increase or decrease in the Assumed Upfront Merger Consideration would increase or decrease, respectively, the number of shares of common stock to be issued by Equillium by 462,963 shares. Keeping the Pro Forma Assumed Upfront Merger Consideration constant, and
26

TABLE OF CONTENTS

assuming an Equillium stock price equal to the Ceiling Price, Equillium would issue 7,410,380 shares. Keeping the Pro Forma Assumed Upfront Merger Consideration constant, a $0.25 decrease from the Ceiling Price would increase the number of shares of common stock Equillium issues at the Closing by 435,904.
Fair value of the Metacrine outstanding stock options and restricted stock units
The estimated fair value of the outstanding Options and RSUs are included in the consideration transferred in accordance with ASC 805. Because no Metacrine employees will be continuing following Closing, the outstanding Options and RSUs which are vested and in-the-money at the Effective Time will be exchanged into shares of common stock of Equillium based on the Exchange Ratio, those shares of common stock being an allocation of the total shares of common stock issued in the Merger as described above, with no incremental consideration attributed to such equity awards. There is no future service requirement. Any unvested Options or RSUs will be cancelled at the Effective Time.
Fair value of warrants to be issued by Equillium to Metacrine warrant holders
Each Warrant that is outstanding and unexercised immediately prior to the Merger will be automatically substituted into a warrant to purchase the number of shares of Equillium common stock equal to the product obtained by multiplying the number of Shares subject to the Warrant immediately prior to the Merger by the Exchange Ratio. Each Warrant will have an exercise price per share of Equillium common stock equal to exercise price per Share immediately prior to the Effective Time divided by the Exchange Ratio. The fair value of the warrants to purchase common stock to be issued to the Metacrine debt holders will be allocated to the pro forma long-term notes payable balance.
The total estimated equity consideration was recorded to common stock at par ($0.0001 per share) and the remainder to additional paid-in capital.
Total estimated preliminary purchase consideration consists of the following:

5. Pro Forma Adjustments
The unaudited pro forma adjustments included in the unaudited pro forma condensed combined financial statements are based on preliminary estimates that may change significantly as additional information is obtained, are as follows:
(A)
Reflects expected use of $6.5 million of Metacrine’s cash-on-hand for costs related to the closing of the Merger including costs directly attributable to the acquisition such as severance and directors and officers liability tail insurance.
(B)
To reduce cash based on the expected transaction costs, see Note 6.
(C)
To reflect the assumed payoff of the Equillium debt held with Oxford Finance and SVB along with a prepayment penalty fee of 1% of the outstanding principal as of June 30, 2022.
(D)
To reflect the assumption of a $15.0 million loan with K2 HealthVentures LLC payment of a $150,000 amendment fee and warrants issued with a fair value of approximately $0.2 million. Both the amendment fee and the fair value of the warrants are recorded as a debt discount, which is classified as a contra-liability against long-term notes payable.
(E)
To reflect the elimination of Metacrine’s historical equity accounts.
(F)
To eliminate the historical interest expense attributed to Equillium’s debt.
(G)
To reverse the income recognized under Bioniz during the year ended December 31, 2021 attributed to the termination of the Almirall option agreement which is considered to be a non-recurring item.
(H)
To reflect the unaudited pro forma condensed combined basic and diluted earnings per share for the periods presented that have been adjusted by the 4,820,230 shares of common stock issued in connection with the Bioniz acquisition and the estimated 12,350,633 shares of common stock to be issued in connection with the Merger, which are assumed outstanding for the year ended December 31, 2021 for pro forma purposes, and to reflect the fair value of the estimated preliminary purchase price consideration totaling $33.3 million as an increase to common stock and additional paid-in capital in the unaudited pro forma condensed combined balance sheet as of June 30, 2022.
(I)
To record the acquired in-process research and development in the unaudited pro forma condensed combined statement of operations and comprehensive loss for the year ended December 31, 2021 for the Bioniz and Mergers as if they were completed on January 1, 2021 and to record the acquired in-process research and development in the unaudited pro forma condensed combined balance sheets as of June 30, 2022 as if the Merger were completed on June 30, 2022.
6. Transaction Costs
The pro forma adjustment related to Merger costs of $4.6 million reflected in accumulated deficit consists of the estimated accrual to be incurred by Equillium and Metacrine in connection with the Merger which was not reflected in each of the historical consolidated balance sheets. Approximately $3.7 million of the estimated Merger costs is attributable to Metacrine, and approximately $0.9 million of the estimated Merger costs is attributable to Equillium.
These Merger-related costs are not expected to have a continuing impact on the results of the combined company. There were no material Merger-related costs included in the historical results of operations of Equillium or Metacrine requiring pro forma adjustment.

The market value of the shares of Equillium common stock to be issued in exchange of shares of Metacrine common stock upon the completion of the Merger will not be known at the time of the Equillium and Metacrine virtual special meetings. The above tables show only historical comparisons. Because (1) the market prices of Equillium common stock and Metacrine common stock will likely fluctuate prior to the Merger, (2) the Equillium stock price used for the purposes of calculating the Exchange Ratio is determined based on the 10 day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the Closing date, provided that in no event will the price per share of Equillium common stock be less than $2.70 or greater than $4.50 and (3) Metacrine’s Closing net cash and aggregate fully diluted capitalization will not be known until shortly prior to the Closing, these comparisons may not provide meaningful information to (i) Equillium stockholders in determining whether to approve the issuance of shares of Equillium common stock to holders of Metacrine common stock in connection with the Merger pursuant to the Merger Agreement or (ii) Metacrine stockholders in determining whether to adopt the Merger Agreement. Equillium stockholders and Metacrine stockholders are encouraged to obtain current market quotations for shares of Equillium common stock and Metacrine common stock and to review carefully the other information contained in this joint proxy statement/prospectus or incorporated by reference in this joint proxy statement/prospectus in considering whether to approve the issuance of shares of Equillium common stock in connection with the Merger pursuant to the terms of the Merger Agreement, in the case of Equillium stockholders, and whether to adopt the Merger Agreement, in the case of Metacrine stockholders. See the section entitled “Where You Can Find More Information” beginning on page 141 of this joint proxy statement/prospectus.
Holders
As of 5:00 p.m. (Eastern Time) on the record date for the Equillium virtual special meeting, 34,352,084 shares of Equillium common stock, held by 49 holders of record, were outstanding and entitled to vote at the Equillium virtual special meeting. As of 5:00 p.m. (Eastern Time) on the record date for the Metacrine virtual special meeting, 42,569,515 shares of Metacrine common stock, held by 35 holders of record, were outstanding and entitled to vote at the Metacrine virtual special meeting.

RISK FACTORS
In addition to the other information included and incorporated by reference into this joint proxy statement/prospectus, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements,” you should carefully consider the following risks before deciding whether to vote for the adoption and approval of the Merger Agreement, in the case of Metacrine stockholders, or for the issuance of shares of Equillium common stock in connection with the Merger, in the case of Equillium stockholders. In addition, you should read and consider the risks associated with each of the businesses of Equillium and Metacrine because these risks will also affect the combined company. These risks can be found in Equillium’s and Metacrine’s respective Quarterly Reports on Form 10-Q for the fiscal quarter ended June 30, 2022, both of which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus. You should also read and consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference into this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information,” beginning on page 141 of this joint proxy statement/prospectus.
Risk Factors Relating to the Merger
The Merger may not be completed on the terms or timeline currently contemplated, or at all. Equillium stockholders and Metacrine stockholders will be subject to a number of material risks if the Merger is not completed.
The consummation of the Merger is subject to numerous conditions, including (1) the approval by the Metacrine stockholders of the Metacrine Merger proposals, (2) the approval by the Equillium stockholders of the Equillium Merger proposals, (3) the effectiveness of the Registration Statement on Form S-4 of which the joint proxy statement and prospectus forms a part, (4) Metacrine’s net cash at the Closing being no less than $23,000,000, and (5) other customary closing conditions. See the section “The Merger Agreement – Conditions to Completion of Merger.”
If the Merger is not completed for any reason, including the failure to complete the Merger by January 2, 2023 (or such later date to which such date may be extended in accordance with the terms of the Merger Agreement), the price of Equillium common stock and/or the price of the Metacrine common stock, par value $0.0001, or Metacrine common stock, may decline to the extent that the market price of Equillium common stock or Metacrine common stock, as applicable, reflects or previously reflected positive market assumptions that the Merger would be completed and the related benefits would be realized. In addition, Equillium and Metacrine have expended and will continue to expend significant management time and resources and have incurred and will continue to incur significant expenses due to legal, advisory, printing and financial services fees related to the Merger. These expenses must be paid regardless of whether the Merger is consummated. If the Merger is not consummated because the Merger Agreement is terminated, Equillium may be required under certain circumstances to pay Metacrine a termination fee of $1,750,000 or Metacrine may be required under certain circumstances to pay Equillium a termination fee of $1,250,000. There is no assurance that the Merger will be consummated. If the Merger is not timely completed, Equillium and Metacrine may have to materially alter their respective business plans, including pausing and/or terminating their current and planned clinical trials and the development of their respective product candidates.
The Merger may be completed even if certain events occur prior to the Closing that materially and adversely affect Metacrine and Equillium.
In general, either party can refuse to complete the Merger if there is a material adverse change affecting the other party between the signing date of the Merger Agreement, and the Closing. However, certain types of changes do not permit either party to refuse to complete the Merger, even if such change could have a material adverse effect on Equillium and Metacrine, including, subject to certain exceptions, among others:
changes or conditions generally affecting the industries in which Equillium or Metacrine, as applicable, operate;
general economic or political conditions or securities, credit, financial or other capital markets conditions, in each case in the United States or any foreign jurisdiction;
any failure, in and of itself, by Equillium or Metacrine, as applicable, to meet any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period;
30

TABLE OF CONTENTS

the public announcement or pendency of the transactions contemplated hereby;
any change, in and of itself, in the market price or trading volume of Equillium’s or Metacrine’s, as applicable, securities or in its credit ratings;
any change in applicable law, regulation or GAAP;
geopolitical conditions, the outbreak or escalation of hostilities, any acts of war, sabotage or terrorism, or any escalation;
any hurricane, tornado, flood, earthquake or other natural disaster;
any epidemic, pandemic or disease outbreak (including Covid-19) and any action by a governmental entity in response thereto;
any litigation arising from allegations of a breach of fiduciary duty or other violation of applicable law relating to the Merger Agreement or the transactions contemplated thereby;
any adverse effects, adverse events or safety observations or reports of new side effects, adverse events or safety observations with respect to Equillium’s or Metacrine’s, as applicable, product candidates that are not reasonably expected to materially affect the likelihood or timing of FDA approval;
any change or modification to any development program of Equillium; or
any taking of any action required pursuant to the Merger Agreement, or not required by the Merger Agreement but taken at the written request of the other party.
If one or more material adverse changes occur and Metacrine and Equillium still complete the Merger, the stock price of the combined company following the Closing may suffer. This in turn may reduce the value of the shares of Equillium common stock to the stockholders of the combined company. See “The Merger Agreement” beginning on page 57 for more information.
The Exchange Ratio will not be determined until shortly prior to the date of the Closing and Equillium and Metacrine stockholders may not know the number of shares to be issued in the Merger or the Exchange Ratio at the time of the stockholder special meetings.
In connection with the Merger, all of the issued and outstanding shares of Metacrine common stock, will be cancelled and converted into the right to receive consideration per share consisting of (i) the exchange ratio, or the Exchange Ratio, determined by dividing (x) (a) 125% of Metacrine’s net cash as of the Closing, or the Upfront Merger Considerations, divided by (b) the price per share of Equillium common stock determined based on the 10 day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the Closing date, provided that in no event will the price per share of Equillium common stock, or the Equillium Stock Price, be less than $2.70 or greater than $4.50 by (y) the aggregate fully diluted shares of Metacrine, or Metacrine’s Closing Capitalization, plus (ii) any cash payable in lieu of fractional shares of Equillium common stock.
The Exchange Ratio is adjustable, as described above, and the price per share of Equillium common stock may be subject to change prior to, during and following the period during which the price per share of Equillium common stock is set for purposes of the Exchange Ratio. Changes in Metacrine’s net cash as of Closing and the price of Equillium common stock prior to the Merger, will each affect the market value of the Merger consideration that Metacrine stockholders actually receive upon the Closing. Stock price changes may result from a variety of factors (many of which are beyond Metacrine’s and Equillium’s control), including the following factors:
changes in Equillium’s and Metacrine’s respective businesses, operations, financial position or prospects;
changes in market assessments of the business, operations, financial position or prospects of either company or the combined company;
manipulation to affect the Exchange Ratio leading up to the Closing;
market assessments of the likelihood that the Merger will be completed;
interest rates, general market, political and economic conditions and other factors generally affecting the price of Equillium’s common stock; and
31

TABLE OF CONTENTS

federal, state and local legislation, governmental regulation and legal developments affecting the businesses of Metacrine or Equillium.
Under the Merger Agreement, there will be no adjustment to the Exchange Ratio for changes in the market price of Equillium common stock within 10 trading days of the Closing, and neither company is permitted to terminate the Merger Agreement or resolicit the vote of Equillium stockholders or Metacrine stockholders solely because of changes in the market price of either company’s stock. You are encouraged to obtain current market quotations for shares of Metacrine common stock and for shares of Equillium common stock before voting.
Because the Merger will be completed after the date of the respective special stockholder meetings, if the special stockholder meeting occurs prior to the finalization of the Closing net cash or more than 10 trading days prior to the Closing, at the time of the applicable special stockholder meeting, the Equillium or Metacrine stockholders may not know the Exchange Ratio or the exact market value of the Equillium common stock that Metacrine stockholders will receive upon completion of the Merger.
subject to the $4.50 per share ceiling, if the 10-day volume weighted average price per share of Equillium common stock increases after the special stockholder meeting but during the window used for determining the Exchange Ratio, Metacrine stockholders can expect to receive less shares of Equillium common stock than was estimated at the time of the special stockholder meeting; and
subject to the $2.70 per share floor, if the 10-day volume weighted average price per share of Equillium common stock decreases after the special stockholder meeting but during the window used for determining the Exchange Ratio, Metacrine stockholders can expect to receive more shares of Equillium common stock than was estimated at the time of the special stockholder meeting.
For illustrative purposes only, we have calculated the potential Exchange Ratio based on the assumptions and sensitivity analysis set forth herein. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price equal to the Floor Price, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.282. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 increase to the Floor Price would decrease the Exchange Ratio to 0.258. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price equal to the Ceiling Price, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.169. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 decrease to the Ceiling Price would increase the Exchange Ratio to 0.179. Assuming (1) the Equillium Stock Price remains constant and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $1,000,000 increase or decrease in the Upfront Merger Consideration would increase or decrease, respectively, the Exchange Ratio by approximately 0.008.
We encourage you to obtain current market quotations of Equillium common stock, Metacrine common stock and consider the foregoing risk before voting. See the section “The Merger Agreement – Treatment of Metacrine Equity Awards and Warrants” beginning on page 70 for more information.
Failure to complete the Merger could negatively affect the stock prices and the future business and financial results of Equillium and Metacrine.
If the Merger is not completed, the ongoing businesses of Equillium and Metacrine may be adversely affected and Equillium and Metacrine will be subject to several risks, including the following:
the possibility that Equillium may be required to pay Metacrine a termination fee of $1,750,000, if the Merger is terminated under qualifying circumstances described under “The Merger Agreement – Termination Fees; Liability for Breach”;
the possibility that Metacrine may be required to pay Equillium a termination fee of $1,250,000 under qualifying circumstances described under “The Merger Agreement – Termination Fees; Liability for Breach”;
the incurrence of costs and expenses relating to the proposed Merger, such as financing, legal, accounting, financial advisor, filing, printing and mailing fees and expenses;
32

TABLE OF CONTENTS

the possibility that Metacrine will be unable to find another potential strategic partner, advance its product candidates, and, as a result, elect to liquidate and dissolve its business;
the possibility that Equillium will be unable to raise sufficient capital or enter into one or more strategic transactions to enable it to carry on its current business plan, including its current and planned clinical trials or expand its pipeline;
the possibility of a change in the trading price of Equillium common stock to the extent current trading prices reflect a market assumption that the Merger will be completed;
the possibility that Equillium or Metacrine could suffer potential negative reactions from their respective employees, partners and vendors; and
the possibility that Equillium or Metacrine could suffer adverse consequences associated with their respective management's focus on the Merger instead of on pursuing other opportunities that could have been beneficial to each company, in each case, without realizing any of the benefits contemplated by the Merger.
In addition, if the Merger is not completed, Equillium or Metacrine could be subject to litigation related to any failure to complete the Merger or to perform their respective obligations under the Merger Agreement.
If the Merger is not completed, Equillium and Metacrine cannot assure their stockholders that these risks will not materialize and will not materially affect the business, financial results and stock prices of Equillium or Metacrine. See the section “The Merger Agreement – Termination of the Merger Agreement” beginning on page 57 for more information.
Metacrine’s net cash at the Closing is subject to change, which could result in Metacrine Stockholders owning a smaller percentage of the combined organization and could even result in the conditions to Closing not being satisfied.
For purposes of the Merger Agreement, Metacrine cash is subject to certain reductions, including, without limitation, certain short and long term liabilities, unpaid expenses related to the Merger, the purchase of a six-year tail to Metacrine’s directors and officers liability insurance policy, and certain other unpaid obligations, including change of control payments, severance and similar payments payable to its current and former employees, the expected cost and expenses of Metacrine liability arising from legal proceedings, payments in order to terminate certain agreements, and payments (up to the unpaid deductible) under D&O insurance reasonably expected to be paid in connection with legal proceedings. In the event the amount of Metacrine’s net cash at the Closing is less than anticipated, Metacrine’s stockholders could hold a significantly smaller portion of the combined organization. Additionally, the Merger Agreement includes a closing condition that requires Metacrine deliver a minimum net cash of $23 million at the Closing. In the event that Metacrine’s net cash falls below this threshold, Equillium would not be obligated to, but may in its sole discretion elect to, consummate the Merger, which would further reduce Metacrine stockholders holding a smaller portion of the combined organization. See the section “The Merger Agreement – Representations and Warranties” beginning on page 60 for more information.
Equillium has the right to pursue certain strategic transactions and to issue and sell equity and convertible securities subject to certain limitations, the occurrence of which may impact Metacrine’s stockholders’ decisions to vote for the Metacrine merger proposals.
The Merger Agreement allows Equillium to issue, sell or agree to issue or sell shares of Equillium capital stock and/or other equity and convertible securities of Equillium that in the aggregate would not equal or exceed 20% of Equillium’s outstanding capital stock, calculated as of the date of the Merger Agreement, without Metacrine’s consent. Any such issuance or sale of Equillium equity or convertible securities may result in Metacrine stockholders holding a smaller portion of the combined organization. Additionally, in limited circumstances, Equillium may enter into and consummate a strategic transaction to exclusively license or sell, or grant an option to exclusively license or sell, certain of its assets, including Equillium’s rights to develop, manufacture and commercialize EQ001 (itolizumab) without Metacrine’s consent. Should such a transaction occur, it is likely to materially impact Equillium’s stock price and its current and future business plans. Metacrine stockholders should consider these possibilities or the lack of such possibilities, among other things disclosed in this joint proxy/prospectus, in determining whether to vote for the Metacrine merger proposals. See the section “The Merger Agreement – Conduct of Business” beginning on page 62 for more information.

TABLE OF CONTENTS

Metacrine stockholders and Equillium stockholders will not be entitled to appraisal rights in the Merger.
Appraisal rights are statutory rights that, if applicable under law, enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction.
Under the DGCL § 262(b), stockholders do not have appraisal rights if the shares of stock they hold, as of the record date for determination of stockholders entitled to vote at the meeting of stockholders to act upon a merger, are either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders. Notwithstanding the foregoing, appraisal rights are available if stockholders are required by the terms of the merger agreement to accept for their shares anything other than (a) shares of stock of the surviving corporation, (b) shares of stock of another corporation that will either be listed on a national securities exchange or held of record by more than 2,000 holders, (c) cash instead of fractional shares or (d) any combination of clauses (a) through (c).
Equillium stockholders will not be entitled to appraisal rights in the Merger with respect to their Equillium shares. Metacrine shares are listed on Nasdaq and are expected to continue to be so listed on the record date for the Metacrine virtual special meeting. Because holders of shares of Metacrine common stock will receive shares of Equillium common stock in the Merger and cash in lieu of fractional shares, holders of shares of Metacrine common stock will also not be entitled to appraisal rights in the Merger with respect to their shares of Metacrine common stock.
The Merger Agreement contains provisions that could discourage a potential competing acquiror of either Equillium or Metacrine or could result in any competing proposal being at a lower price than it might otherwise be.
The Merger Agreement contains “no-shop” provisions that, subject to limited exceptions, restrict Metacrine’s and Equillium’s ability to solicit, encourage, facilitate or discuss competing third-party proposals to acquire all or a significant part of Equillium or Metacrine. In addition, the other party generally has an opportunity to offer to modify the terms of the proposed merger in response to any competing acquisition proposals that may be made before such board of directors may withdraw or qualify its recommendation regarding the proposals described herein. In specified circumstances, Equillium or Metacrine may be required to pay a termination fee to the other party due to the termination of the Merger Agreement.
These provisions could discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of Equillium or Metacrine from considering or proposing that acquisition, even if it were prepared to pay consideration with a higher value than that market value proposed to be received or realized in the Merger, or might result in a potential competing acquiror proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee or expenses that may become payable in certain circumstances.
If the Merger Agreement is terminated and either Equillium or Metacrine attempts to seek another business combination, there is no assurance that either Equillium or Metacrine, as applicable, may be able to negotiate a transaction with another party on terms comparable or better than the terms of the Merger. See the section “The Merger Agreement – No Solicitation of Alternative Proposals” beginning on page 65 for more information.
The pendency of the Merger could adversely affect the business and operations of Equillium and Metacrine.
In connection with the Merger, some prospective partners of each of Equillium and Metacrine may delay or defer decisions or reduce their level of business with either or both of the companies, any of which could negatively affect the financials and business plans of Equillium and Metacrine, regardless of whether the Merger is completed. In addition, due to operating covenants in the Merger Agreement, each of Equillium and Metacrine may be unable, during the pendency of the Merger, to pursue strategic transactions, undertake significant capital projects, undertake certain significant financing transactions and otherwise pursue other actions without the consent of the other party or as otherwise discussed elsewhere in these risk factors, even if such actions would prove beneficial. Any of these effects could adversely affect Equillium’s or Metacrine’s respective business prior to the completion of the Merger. Moreover, the pursuit of the Merger and the preparation for the integration of the companies may place a significant burden on the management and personnel of both companies. The diversion of management's attention away from operating the companies in the ordinary course could adversely affect Equillium’s and Metacrine’s financial results and the advancement of their respective product candidates.

TABLE OF CONTENTS

Current Equillium stockholders will have a reduced ownership and voting power in the combined company after the Merger.
After the completion of the Merger, the current securityholders of Equillium and Metacrine will own a smaller percentage of the combined company than their ownership in their respective companies prior to the Merger.
The aggregate value for each share of Metacrine common stock will not be determined until shortly prior to the closing of the Merger. For illustrative purposes only, we have provided the below assumptions and sensitivity analysis to inform your decision.
Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price equal to the Floor Price, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.282. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 increase to the Floor Price would decrease the Exchange Ratio to 0.258. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration, (2) an Equillium Stock Price equal to the Ceiling Price, and (3) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, the Exchange Ratio would equal 0.169. Assuming (1) an Upfront Merger Consideration equal to the Assumed Upfront Merger Consideration and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $0.25 decrease to the Ceiling Price would increase the Exchange Ratio to 0.179. Assuming (1) the Equillium Stock Price remains constant and (2) Metacrine’s Closing Capitalization is equal to the Assumed Metacrine Closing Capitalization, a $1,000,000 increase or decrease in the Upfront Merger Consideration would increase or decrease, respectively, the Exchange Ratio by approximately 0.008. We encourage you to obtain current market quotations of Equillium common stock and Metacrine common stock before voting.
Based on the Assumed Upfront Merger Consideration, Equillium estimates that it may issue between 7.5 and 12.5 million shares of its common stock to Metacrine stockholders in connection with the Closing. Based on the Assumed Upfront Merger Consideration and 34,352,084 shares of Equillium common stock outstanding as of November 9, 2022, we estimate that current Equillium stockholders will own between 82.08% and 73.32% of the outstanding common stock of the combined company and former Metacrine equityholders will own between 17.92% and 26.68% of the outstanding common stock of the combined company.
Equillium stockholders and Metacrine stockholders currently have the right to vote for their respective directors and on certain other matters affecting their company. If and when the Merger occurs, each Equillium stockholder will remain a stockholder of Equillium with a percentage ownership of Equillium that will be smaller than the stockholder’s percentage of Equillium prior to the Merger (without considering such stockholder’s current ownership of Metacrine shares, if any). Correspondingly, each Metacrine stockholder who receives shares of Equillium common stock will become an Equillium stockholder with a percentage ownership of Equillium that will be smaller than the stockholder’s percentage ownership of Metacrine (without considering such stockholder’s current ownership of Equillium common stock). Equillium stockholders will have less voting power in Equillium than they currently have, and former Metacrine stockholders will have less voting power in Equillium than they now have in Metacrine. Each of Equillium and Metacrine’s pre-Merger stockholders, respectively, as a group, will be able to exercise less influence over the management and policies of the combined company following the consummation of the Merger than immediately prior to the consummation of the Merger. See the section “The Merger Agreement – Treatment of Metacrine Equity Awards and Warrants” beginning on page 70 for more information.
The market price of shares of Equillium common stock may be affected by factors different from those that historically have affected shares of Metacrine common stock and will continue to fluctuate after the Merger.
Upon completion of the Merger, holders of Metacrine common stock will become holders of Equillium common stock. Equillium’s business differs from that of Metacrine in certain respects, and, accordingly, the financial position or results of operations and/or cash flows of Equillium after the Merger, as well as the market price of shares of Equillium common stock, may be affected by factors different from those currently affecting the financial position or results of operations and/or cash flows of Metacrine. In addition, the stock market has experienced significant price and volume fluctuations in recent times which, if they continue to occur, could have a material adverse effect on the market for, or liquidity of, the Equillium common stock, regardless of Equillium's actual operating performance. As a result, the market price of shares of Equillium common stock may fluctuate significantly following completion of the Merger, and holders of Metacrine common stock could lose some or all of the value of their investment in Equillium common stock.

TABLE OF CONTENTS

Directors and executive officers of Equillium and Metacrine have financial interests in the Merger that may be different from, or in addition to, those of other Equillium stockholders and Metacrine stockholders, which could have influenced their decisions to support or approve the Merger.
In considering whether to approve the proposals at the special meetings, Equillium and Metacrine stockholders should recognize that directors and executive officers of Equillium and Metacrine have interests in the Merger that may differ from, or that are in addition to, their interests as stockholders of Equillium and stockholders of Metacrine. The Equillium Board and the Metacrine Board were aware of these interests at the time each approved the Merger Agreement. These interests may cause Equillium's and Metacrine's directors and executive officers to view the Merger differently than you may view it as a stockholder. The interests include, among others, severance benefits, continued indemnification and the right to accelerated vesting. For example, Metacrine previously entered into severance and bonus agreements with certain members of management that provide them with cash severance payments, certain health insurance coverage and the acceleration of their outstanding equity awards in the event their employment is terminated in connection with a change of control of Metacrine.
The opinions obtained by the Equillium Board and Metacrine Board from their respective financial advisors do not and will not reflect changes in circumstances after the date of such opinions.
The Equillium Board received a written opinion, or the VPA Opinion, dated September 6, 2022 from Vantage Point Advisors, Inc., its financial advisor, that the Merger transaction was fair, from a financial point of view, to the Equillium common stockholders, as of such date, and based on and subject to the qualifications, limitations and assumptions set forth in the VPA Opinion (including, without limitation, the accuracy and completeness of the audited and unaudited financial statements, forecasts and other information provided to it by the Equillium Board and the assurances from the Equillium Board that they were unaware of any facts or circumstances that would make the VPA Opinion incomplete or misleading). The VPA Opinion did not constitute a recommendation to the Equillium Board (or any member thereof) as to how it should vote with respect to the Merger transaction. The Metacrine Board received written opinions from MTS, an affiliate of its financial advisor MTS Health Partners, LP, or MTS Partners, dated September 2, 2022, or the September MTS Opinion, and October 19, 2022, or the October MTS Opinion and together with the September Opinion, the MTS Opinions, that as of such dates and based upon and subject to the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of review undertaken by MTS, as set forth in the MTS Opinions, the Exchange Ratio employed in the Merger pursuant to the Merger Agreement was fair to the holders of shares of Metacrine common stock (other than Excluded Shares), from a financial point of view. Changes in the operations or prospects of Equillium or Metacrine, general market and economic conditions and other factors that may be beyond the control of Equillium and Metacrine, and on which the above-described opinions were based, may alter the value of Equillium or Metacrine or the prices of shares of Equillium Common stock or Metacrine common stock by the time the Merger is completed. Except for the October MTS Opinion, Equillium and Metacrine have not obtained, and do not expect to request, updated opinions from their respective financial advisors. None of the above-listed opinions speak to any date other than the date of such opinion. See the sections “The Merger Agreement – Opinion of Equillium’s Financial Advisor” beginning on page 96, and “The Merger Agreement – Opinions of Metacrine’s Financial Advisor” beginning on page 103 for more information.
Due to the Merger, the ability of Equillium to use Metacrine's net operating losses to offset future taxable income may be restricted and these net operating losses could expire or otherwise be unavailable.
As of December 31, 2021, Metacrine had federal net operating loss carryforwards, which we refer to as NOLs, of approximately $164.5 million. In general, under Section 382 of the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-ownership change NOLs to offset future taxable income. As of December 31, 2021, Metacrine has not completed a Section 382 limitation study. If the Merger is completed, Metacrine's existing NOLs may be subject to limitations. In addition, if Equillium undergoes any subsequent ownership change, its ability to utilize NOLs would be limited.
The Merger is intended to be a taxable transaction and does not qualify as a “reorganization” for U.S. federal income tax purposes. U.S. holders will be required to recognize gain or loss for U.S. federal income tax purposes at the time of the exchange of their Metacrine common stock for the merger consideration in the Merger.
U.S. holders of Metacrine common stock will recognize gains or losses for U.S. federal income tax purposes on each share of Metacrine common stock surrendered in the Merger in an amount equal to the difference between (1) the fair market value of the merger consideration received in exchange for such surrendered share upon completion
36

TABLE OF CONTENTS

of the Merger and (2) the holder's basis in the share of Metacrine common stock surrendered. Any gain or loss recognized would be long-term capital gain or loss if the U.S. holder's holding period in a particular block of Metacrine common stock exceeds one year at the effective time of the Merger. Long-term capital gain of non-corporate U.S. holders (including individuals) is taxed at reduced U.S. federal income tax rates. See the section “Material U.S. Federal Income Tax Consequences” beginning on page 123 for more information.
Risk Factors Relating to Equillium Following the Merger
Operational Risks
Equillium expects to incur substantial costs and expenses related to the Merger.
Equillium expects to incur substantial costs and expenses in connection with completing the Merger and integrating Metacrine’s business. While Equillium has assumed that a certain level of transaction and integration costs and expenses would be incurred, there are a number of factors beyond its control that could affect the total amount or the timing of its integration costs and expenses, including any Metacrine liabilities that arise, or become known, following the Closing. Many of the costs and expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. Due to these factors, the transaction and integration costs and expenses could be greater or could be incurred over a longer period of time than Equillium currently expects.
Equillium intends to enter into an arrangement to assume Metacrine’s existing debt facility and to retire Equillium’s current debt facility, which, regardless of whether such arrangement is consummated, will have a material impact on Equillium’s financials.
In connection with the Closing, Equillium intends to enter into an arrangement with Metacrine’s current lender, K2 HealthVentures LLC, to amend and assume Metacrine’s current debt facility with an outstanding principal balance of $15 million, or the K2 Debt Arrangement. If Equillium and K2 HealthVentures LLC are able to consummate the K2 Debt Arrangement, Equillium would retire its existing debt facility with Oxford Finance LLC and Silicon Valley Bank, which currently has an outstanding principal amount of $10 million, or the Existing Debt Facility. After retiring the Existing Debt Facility and as a result of the Merger, Equillium anticipates adding approximately $35 million in cash to its balance sheet at the Closing. As a condition of the K2 Debt Arrangement, K2 HealthVentures LLC may require Equillium to provide additional warrant coverage, which, if issued and exercised, would dilute both Equillium and Metacrine stockholders’ ownership in the combined organization.
There are no assurances that Equillium and K2 HealthVentures LLC will be able to agree on terms mutually acceptable to each other with respect to the K2 Debt Arrangement. If Equillium and K2 HealthVentures LLC are unable to agree on acceptable terms for the K2 Debt Arrangement, Metacrine’s existing debt facility with K2 HealthVentures LLC will be retired at the Closing. If Metacrine’s existing debt facility is retired at the Closing, Equillium would expect to add approximately $27 million in cash to its balance sheet at the Closing and continue to maintain its Existing Debt Facility.
The restrictions and obligations contained in the K2 Debt Arrangement, if consummated, may differ from those under the Existing Debt Facility and Metacrine’s existing debt facility. Equillium anticipates the terms of the K2 Debt Arrangement will subject its business to the risks normally associated with debt financing, including the following risks:
Equillium’s cash flow may be insufficient to meet required payments of principal and interest, or require Equillium to dedicate a substantial portion of its cash flow to pay its debt and the interest associated with its debt rather than to other areas of its business;
it may be more difficult for Equillium to obtain additional financing in the future for its operations, working capital requirements, capital expenditures, debt service or other general requirements;
Equillium may be more vulnerable in the event of adverse economic and industry conditions or a downturn in its business;
Equillium may be placed at a competitive disadvantage compared to its competitors that have less debt;
Equillium may be subject to limitations with respect to its activities including certain future strategic transactions; and
37

TABLE OF CONTENTS

Equillium may not be able to refinance at all or on favorable terms, as its debt matures.
If any of the above risks occurred, Equillium’s financial condition and results of operations could be materially adversely affected. See section “Description of the Merger” beginning on page 21 for more information.
Equillium will require additional capital to fund its operations, which may not be available on acceptable terms, or at all. Failure to obtain this necessary capital when needed may force Equillium to delay, limit or terminate certain of its product development programs, commercialization efforts or other operations.
The development of biotechnology product candidates is capital-intensive. As Equillium conducts non-clinical research and clinical development of its product candidates, Equillium will need substantial additional funds to maintain and expand its capabilities in a variety of areas including research, clinical development, regulatory affairs, product quality assurance, and pharmacovigilance. In addition, if Equillium obtains marketing approval for any of its product candidates, Equillium expects to incur significant commercialization expenses for marketing, sales, manufacturing and distribution. Some of those commercialization investments may be made at-risk in advance of receiving an approval. Because the outcome of any preclinical study or clinical trial is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our drug candidates. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts.
Based on Equillium’s current operating plan, Equillium believes that its existing cash and cash equivalents, together with the cash proceeds from the Merger, will be sufficient to fund its operating expenses and capital expenditure requirements through at least calendar year 2023. In particular, Equillium expects the cash proceeds from the Merger, together with its existing cash and cash equivalents, will allow it to advance its clinical development plans through topline data from the EQUALISE study, interim data from its planned Phase 2 study of EQ101 in alopecia areata and interim data from its planned Phase 1 study of EQ102 in healthy volunteers as well as in subjects with celiac disease. Equillium’s operating plan may change as a result of many factors currently unknown to it, and Equillium may need to seek additional funding sooner than planned.
Until such time as Equillium can generate significant revenue from sales of its product candidates, if ever, Equillium expects to finance its cash needs through equity offerings, debt financings or other capital sources, including potentially grants, collaborations, licenses or other similar arrangements. Accordingly, Equillium will need to continue to rely on additional financing to achieve its business objectives. If Equillium is unable to raise additional capital when needed, its ability to grow and support its business and to respond to market challenges could be significantly limited, which could have a material adverse effect on its business, financial condition and results of operations. Any additional capital raising efforts may divert Equillium’s management from their day-to-day activities, which may adversely affect its ability to develop and, if approved, commercialize its current and any future drug candidates. Additional funding may not be available on acceptable terms, or at all.
If the combined company is unable to compete effectively, the results of operations of the combined company will be materially and adversely affected.
The competitors of the combined company include major pharmaceutical and biotechnology companies, academic institutions, government agencies, public and private research institutions, and smaller or early stage companies, of which many are well-capitalized. The competitiveness of the combined company, is based on factors including the efficacy, safety and convenience of our product candidates, our combined ability to raise capital and enter into strategic transactions, and recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials. If the combined company is unable to compete based on such factors, the combined company's results of operations and business prospects could be harmed.
The combined company will have numerous product candidates and two discovery platforms and will need to prioritize its research programs and focus development of its product candidates on the potential treatment of certain indications. As a result, the combined company may forego or delay pursuit of opportunities with other indications or for any future product candidates that later prove to have greater commercial potential. The resource allocation decisions of the combined company may cause it to fail to capitalize on viable commercial products or profitable market opportunities. Such failure may result in the combine company being unable to
38

TABLE OF CONTENTS

raise additional capital to continue to fund its existing programs and operations, and could lead to stockholders losing all or substantially all of their investment in Equillium.
The business operations of the combined company will be subject to various and changing federal, state, local and foreign laws and regulations that could result in costs or sanctions that adversely affect the business and results of operations of the combined company.
The combined company will operate in an increasingly complex regulatory environment. Businesses in the countries in combined company will operate are subject to local, legal and political environments and regulations including with respect to employment, tax, statutory supervision and reporting and trade restriction. These regulations and environments are also subject to change.
Adjusting business operations to changing environments and regulations may be costly and could potentially render the particular business operations uneconomical, which may adversely affect the profitability of the combined company or lead to a change in the business operations.
Notwithstanding the best efforts of the combined company, it may not be in compliance with all regulations in the countries in which it operates at all times and may be subject to sanctions, penalties or fines as a result. These sanctions, penalties or fines may materially and adversely impact the profitability of the combined.
Other Risks
The historical and unaudited pro forma condensed combined financial information included elsewhere in this joint proxy statement/prospectus may not be representative of Equillium’s results after the Merger, and accordingly, you have limited financial information on which to evaluate the combined company.
Equillium and Metacrine will continue to operate as separate companies prior to the Merger. Equillium and Metacrine have no prior history as a combined company. The historical financial statements of Metacrine may be different from those that would have resulted had Metacrine been operated as part of Equillium. The pro forma condensed combined financial information appearing elsewhere herein has been presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that actually would have occurred had the Merger been completed as of the dates indicated, nor is it indicative of the future operating results or financial position of the combined company. The unaudited pro forma condensed combined financial information reflects adjustments, which are based upon preliminary estimates, to allocate the aggregate consideration to Metacrine assets and liabilities. The aggregate consideration allocation reflected in the pro forma condensed combined financial information included in this joint proxy statement/prospectus is preliminary, and the final allocation of the aggregate consideration will be based upon the actual aggregate consideration and the fair value of the assets and liabilities of Metacrine as of the date of the completion of the Merger. The unaudited pro forma condensed combined financial information does not reflect future events that may occur after the Merger, including the incurrence of costs related to the planned integration of Metacrine, any future non-recurring charges resulting from the Merger, or consider potential effects of future market conditions on expense efficiencies, if any. The unaudited pro forma financial information presented in this joint proxy statement/prospectus is based in part on certain assumptions regarding the Merger that Equillium believes are reasonable under the circumstances. Equillium cannot assure you that the assumptions will prove to be accurate over time.
The Equillium and Metacrine prospective financial information is inherently subject to uncertainties.
While presented with numeric specificity, the Equillium and Metacrine prospective financial information provided in this document was prepared based on numerous variables and assumptions (including, but not limited to, those related to industry performance and competition and general business, economic, market and financial conditions, and additional matters specific to Equillium or Metacrine business, as applicable, including the possibility of consummating certain other strategic transactions) that are inherently subjective and uncertain and are largely beyond the control of the respective management of each. As a result, actual results may differ from the prospective financial information. Important factors that may affect actual results and cause these projected financial forecasts to not be achieved include, but are not limited to, risks and uncertainties relating to Equillium’s or Metacrine’s business, as applicable (including each company’s ability to achieve strategic goals, objectives and targets over applicable periods) and general industry, business, competitive and economic conditions.

TABLE OF CONTENTS

Equillium and Metacrine may be targets of securities class action and derivative lawsuits which could result in substantial costs and may delay or prevent the Merger from being completed.
Securities class action lawsuits and derivative lawsuits are often brought against public companies that have entered into merger agreements. Even if the lawsuits are without merit, defending against these claims could result in substantial costs and divert management time and resources. An adverse judgment could result in monetary damages, which could have a negative impact on Equillium’s and Metacrine’s respective liquidity and financial condition. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting completion of the Merger, then that injunction may delay or prevent the Merger from being completed, which may adversely affect Equillium’s and Metacrine’s respective business, financial position and results of operations.
Other Risks Related to Equillium’s Business and Metacrine’s business
Equillium’s and Metacrine’s businesses are, and following completion of the transaction Equillium will continue to be, subject to the risks described above and in Equillium’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as amended and as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and Metacrine’s Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2022, as amended and as updated by subsequent Current Reports on Form 8-K, all of which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus.

The Equillium Board recommends that Equillium stockholders vote “FOR” the Equillium stock issuance proposal and “FOR” the Equillium adjournment proposal.
See also the section entitled “The Merger—Reasons for the Merger; Recommendation of the Merger by the Equillium Board” beginning on page 87.
Record Date for the Equillium virtual special meeting; Stock Entitled to Vote
Only holders of record of shares of Equillium common stock at the close of business on November 9, 2022, the record date for the Equillium virtual special meeting, will be entitled to notice of, and to vote at, the Equillium virtual special meeting and any postponements or adjournments thereof. Holders of Equillium common stock at the close of business on the Equillium record date may cast one vote for each share of Equillium common stock that you owned as of the Equillium record date, including (i) shares held directly in the name of the holder of record and (ii) shares held on behalf of the holder as the beneficial owner in street name through a broker, bank, or other nominee.
On the Equillium record date, there were outstanding a total of 34,352,084 shares of Equillium common stock entitled to vote at the Equillium virtual special meeting.
Solicitation of Proxies
The cost of proxy solicitation for the Equillium virtual special meeting, if any, and expenses for the filing, printing and mailing of this joint proxy statement/prospectus will be borne by Equillium. In addition to the use of the mail, proxies may be solicited by officers and directors and regular employees of Equillium, without additional remuneration, by personal interview, telephone, electronic communication or otherwise. Equillium will
43

TABLE OF CONTENTS

also request brokerage firms, nominees, custodians and fiduciaries to forward proxy materials to the beneficial owners of shares held of record on the Equillium record date and will provide customary reimbursement to such firms for the cost of forwarding these materials. Equillium has not retained a proxy solicitor to assist in its solicitation of proxies.
Quorum
The holders of a majority of the voting power of Equillium’s outstanding shares of common stock entitled to vote as of the close of business on the Equillium record date must be virtually present or represented by proxy to constitute a quorum to conduct the Equillium virtual special meeting. All shares of Equillium common stock represented at the Equillium virtual special meeting, including abstentions and broker non-votes (shares held by a broker or nominee that are represented at the meeting, but with respect to which the broker or nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal), will be treated as present for purposes of determining the presence or absence of a quorum to conduct the Equillium virtual special meeting.
Vote Required
Equillium Stock Issuance Proposal. Approval of the Equillium stock issuance proposal requires the affirmative vote of the holders of Equillium common stock representing a majority of the votes cast on such matter at the Equillium virtual special meeting (provided that a quorum exists).
Equillium Adjournment Proposal. Approval of the Equillium adjournment proposal requires the affirmative vote of the holders of shares of Equillium common stock representing a majority of votes cast on such matter at the Equillium virtual special meeting (whether or not a quorum is present).
The chairperson of the Equillium virtual special meeting may, if necessary, adjourn the Equillium virtual special meeting for the purpose of soliciting additional proxies (whether or not a quorum exists).
Abstentions and Broker Non-Votes
If you are an Equillium stockholder, abstentions and broker “non-votes” have no effect on the outcome of the stock issuance proposal or the Equillium adjournment proposal. Shares of Equillium common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If you are an Equillium stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Equillium common stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the Equillium virtual special meeting and will be voted “FOR” that proposal. Your failure to cast a vote will also make it more difficult to meet the quorum requirement with respect to organizing the meeting.
Voting Power of Equillium’s Directors and Executive Officers
On the Equillium record date, 25.5% of the outstanding Equillium common stock was held by Equillium directors and executive officers and their respective affiliates. Equillium currently expects that its directors and executive officers will vote their shares in favor of Equillium stock issuance proposal and the Equillium adjournment proposal.
Attending the Equillium virtual special meeting
All holders of Equillium common stock, including stockholders of record and stockholders who hold shares through banks, brokers or other nominees, are invited to virtually attend the Equillium virtual special meeting. Stockholders of record can vote at the special meeting. In order to attend the Equillium virtual special meeting, as well as vote and submit your questions during the live webcast of the meeting, you will need to visit www.virtualshareholdermeeting.com/EQ2022SM and enter the 16-digit Control Number shown on your proxy card. Please be sure to follow instructions found on your proxy card and/or voting authorization form.
Voting of Proxies by Record Stockholders
A proxy card is enclosed for use by Equillium stockholders of record. Equillium requests that its record stockholders sign the accompanying proxy and return it promptly in the enclosed postage-paid envelope. You may also vote your shares by telephone or through the Internet. Information and applicable deadlines for voting
44

TABLE OF CONTENTS

by telephone or through the Internet are set forth on the enclosed proxy card. Shares of Equillium common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If you are an Equillium stockholder of record and you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of Equillium common stock represented by your proxy will be counted as present for purposes of determining the presence of a quorum for the Equillium virtual special meeting and will be voted “FOR” that proposal.
At the date hereof, Equillium management has no knowledge of any business that will be presented for consideration at the special meeting and which would be required to be set forth in this joint proxy statement/prospectus other than the matters set forth in Equillium’s accompanying Notice of Special Meeting of Stockholders. In accordance with Equillium’s bylaws and Delaware law, business transacted at the Equillium virtual special meeting will be limited to those matters set forth in such notice. Nonetheless, if any other matter is properly presented at the Equillium virtual special meeting for consideration, it is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their best judgment on such matter.
Your vote is important. Whether or not you expect to attend the Equillium virtual special meeting in person, we urge you to vote your shares as promptly as possible by (1) accessing the Internet website specified on your proxy card; (2) calling the toll-free number specified on your proxy card; or (3) signing and returning the enclosed proxy card in the postage-paid envelope provided, so that your shares may be represented and voted at the Equillium virtual special meeting.
Shares Held in Street Name
If you hold your shares of Equillium common stock in a stock brokerage account or if your shares are held by a bank or nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares if you wish them to be counted. Please follow the voting instructions provided by your broker, bank or nominee. Please note that you may not vote shares held in street name by returning a proxy card directly to Equillium or by voting at the Equillium virtual special meeting. Further, brokers who hold shares of Equillium common stock on behalf of their customers may not vote those shares without specific instructions from their customers.
If you hold your Equillium common stock in street name and you do not instruct your broker on how to vote any of your shares, your broker may not vote those shares. For a discussion of the consequences of such broker non-votes, see “The Equillium virtual special meeting—Abstentions and Broker Non-Votes” beginning on page 44 of this joint proxy statement/prospectus.
Revocability of Proxies and Changes to an Equillium Stockholder’s Vote
If you are a holder of shares of Equillium common stock as of the record date for the Equillium virtual special meeting, you have the power to revoke your proxy at any time before your proxy is voted at the Equillium virtual special meeting. You can revoke your proxy in one of four ways:
you can send a signed notice of revocation that is received by Equillium prior to your shares being voted, stating that you would like to revoke your proxy, to Equillium’s corporate secretary at Equillium’s corporate headquarters, 2223 Avenida de la Playa, Suite 105, La Jolla, California 92037;
you can grant a new, valid proxy bearing a later date (by Internet, telephone or mail) that is received by Equillium prior to your shares being voted;
you can vote again by telephone or the Internet at a later time; or
if you are a holder of record, by voting at the Equillium virtual special meeting, which will automatically cancel any proxy previously given, or you may revoke your proxy by attending the virtual special meeting, but your attendance alone will not revoke any proxy that you have previously given.
The latest dated completed proxy will be the one that counts. Written notices of revocation and other communications with respect to the revocation of any proxies should be addressed to:
Equillium, Inc.
2223 Avenida de la Playa, Suite 105
La Jolla, California 92037
Attn: Corporate Secretary
45

TABLE OF CONTENTS

If you are an Equillium stockholder whose shares of Equillium common stock are held in “street name” by a bank, broker, or other nominee, you may revoke your proxy or voting instructions and vote your shares in person at the Equillium virtual special meeting only in accordance with applicable rules and procedures as employed by your bank, broker, or other nominee. If your shares are held in “street name” in an account at a bank, broker, or other nominee, you must follow the directions you receive from your bank, broker, or other nominee in order to change or revoke your proxy or voting instructions and should contact your bank, broker, or other nominee to do so.
Adjournments
Although it is not currently expected, the Equillium virtual special meeting may be adjourned for the purpose of soliciting additional proxies if Equillium has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the Equillium stock issuance proposal. Adjourning the Equillium virtual special meeting requires the affirmative vote of the holders of Equillium common stock representing a majority of the votes cast on such matter at the Equillium virtual special meeting (whether or not a quorum is present), or in the case that no Equillium stockholders are present at the Equillium virtual special meeting, any Equillium officer entitled to preside at or to act as secretary of the Equillium virtual special meeting may adjourn the Equillium virtual special meeting. Pursuant to the Equillium bylaws, notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which adjournment is taken. If the adjournment is for more than 30 days or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the Equillium virtual special meeting. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting. If the Equillium virtual special meeting is adjourned, stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use. The Merger Agreement provides that the Equillium virtual special meeting will not be adjourned to a date that is more than 15 calendar days after the date for which the Equillium virtual special meeting was originally scheduled.
Postponements
At any time prior to convening the Equillium virtual special meeting, the Equillium Board may postpone the Equillium virtual special meeting for any reason without the approval of the Equillium stockholders. The Merger Agreement provides that the Equillium virtual special meeting will not be postponed to a date that is more than 15 calendar days after the date for which the Equillium virtual special meeting was originally scheduled. Although it is not currently expected, the Equillium Board may postpone the Equillium virtual special meeting for the purpose of soliciting additional proxies if Equillium has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the Equillium stock issuance proposal. If the Equillium virtual special meeting is postponed, stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use.
Stockholder List
A list of Equillium stockholders entitled to vote at the Equillium virtual special meeting will be available for inspection at Equillium’s principal executive offices, located at 2223 Avenida de la Playa, Suite 105, La Jolla, California 92037, at least 10 days prior to the date of the Equillium virtual special meeting and continuing through the date thereof for any purpose germane to the Equillium virtual special meeting, between the hours of 9:00 a.m. and 4:30 p.m., local time.
Tabulation of Votes
A representative of Equillium’s mailing and tabulating agent, Broadridge Financial Solutions, will tabulate the votes and Equillium’s corporate secretary will act as inspector of elections.
How You Can Reduce the Number of Copies of Equillium’s Proxy Materials You Receive
Equillium has adopted a procedure approved by the Securities and Exchange Commission called “householding.” Under this procedure, stockholders of record who have the same address and last name and who do not participate in electronic delivery of proxy materials will receive only one copy of the proxy materials,
46

TABLE OF CONTENTS

unless one or more of these stockholders notifies Equillium that they wish to continue receiving individual copies. This procedure reduces Equillium’s printing costs and postage fees. Stockholders who wish to participate in householding will continue to receive separate proxy cards.
If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the proxy materials, or if you hold stock in more than one account, and, in either case, you wish to receive only a single copy of the proxy materials for your household, please contact your broker.
If you participate in householding and wish to receive a separate copy of the proxy materials, or if you do not wish to continue to participate in householding and prefer to receive separate copies of the proxy materials in the future, please contact your broker or Equillium. Direct your written request to Equillium, Inc., Investor Relations, 2223 Avenida de la Playa, Suite 105, La Jolla, California 92037 or contact Investor Relations at (858) 240-1200 or by email at ir@equilliumbio.com.
Beneficial owners can request information about householding from their banks, brokers, or other holders of record.
Assistance
If you need assistance in completing your proxy card or have questions regarding the Equillium virtual special meeting, please contact Investor Relations at (858) 240-1200 or email ir@equilliumbio.com.

If you are a Metacrine stockholder whose shares of common stock are held in “street name” by a bank, broker, or other nominee, you may revoke your proxy or voting instructions and vote your shares in person at the Metacrine virtual special meeting only in accordance with applicable rules and procedures as employed by your bank, broker, or other nominee. If your shares are held in “street name” in an account at a bank, broker, or other nominee, you must follow the directions you receive from your bank, broker, or other nominee in order to change or revoke your proxy or voting instructions and should contact your bank, broker, or other nominee to do so.
Adjournments
Although it is not currently expected, the Metacrine virtual special meeting may be adjourned for the purpose of soliciting additional proxies if Metacrine has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the Metacrine merger proposal. Adjourning the Metacrine virtual special meeting requires the affirmative vote of the holders of Metacrine common stock representing a majority of the votes cast on such matter at the Metacrine virtual special meeting (whether or not a quorum is present), or in the case that no Metacrine stockholders are present at the Metacrine virtual special meeting, any Metacrine officer entitled to preside at or to act as secretary of the Metacrine virtual special meeting may adjourn the Metacrine virtual special meeting. Pursuant to the Metacrine bylaws, notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which adjournment is taken. If the adjournment is for more than 30 days or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the Metacrine virtual special meeting. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting. If the Metacrine virtual special meeting is adjourned, stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use. The Merger Agreement provides that the Metacrine virtual special meeting will not be adjourned to a date that is more than 15 calendar days after the date for which the Metacrine virtual special meeting was originally scheduled.
Postponements
At any time prior to convening the Metacrine virtual special meeting, the Metacrine Board may postpone the Metacrine virtual special meeting for any reason without the approval of the Metacrine stockholders. The Merger Agreement provides that the Metacrine virtual special meeting will not be postponed to a date that is more than 15 calendar days after the date for which the Metacrine virtual special meeting was originally scheduled. Although it is not currently expected, the Metacrine Board may postpone the Metacrine virtual special meeting for the purpose of soliciting additional proxies if Metacrine has not received sufficient proxies to constitute a quorum or sufficient votes for approval of the Metacrine merger proposal. If the Metacrine virtual special meeting is postponed, stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use.
Stockholder List
A list of Metacrine stockholders entitled to vote at the Metacrine virtual special meeting will be available for inspection at Metacrine’s principal executive offices, located at 4225 Executive Square, Suite 600, San Diego, CA 92037, at least 10 days prior to the date of the Metacrine virtual special meeting and continuing through the date thereof for any purpose germane to the Metacrine virtual special meeting, between the hours of 9:00 a.m. and 4:30 p.m., local time.
Tabulation of Votes
A representative of Metacrine’s mailing and tabulating agent, Broadridge Financial Solutions, will tabulate the votes and Metacrine’s corporate secretary will act as inspector of elections.
How You Can Reduce the Number of Copies of Metacrine’s Proxy Materials You Receive
Metacrine has adopted a procedure approved by the Securities and Exchange Commission called “householding.” Under this procedure, stockholders of record who have the same address and last name and who do not participate in electronic delivery of proxy materials will receive only one copy of the proxy materials, unless one or more of these stockholders notifies Metacrine that they wish to continue receiving individual copies. This procedure reduces Metacrine’s printing costs and postage fees. Stockholders who wish to participate in householding will continue to receive separate proxy cards.
53

TABLE OF CONTENTS

If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the proxy materials, or if you hold stock in more than one account, and, in either case, you wish to receive only a single copy of the proxy materials for your household, please contact your broker.
If you participate in householding and wish to receive a separate copy of the proxy materials, or if you do not wish to continue to participate in householding and prefer to receive separate copies of the proxy materials in the future, please contact your broker or Metacrine. Direct your written request to Metacrine, Inc., Investor Relations, 4225 Executive Square, Suite 600, San Diego, CA 92037 or contact Investor Relations at (858) 369-7800 or by email at investors@metacrine.com.
Beneficial owners can request information about householding from their banks, brokers, or other holders of record.

If you need assistance in completing your proxy card or have questions regarding the Metacrine virtual special meeting, please contact Morrow Sodali, LLC, the proxy solicitor for Metacrine, by telephone toll-free at (800) 662-5200.

METACRINE PROPOSALS

Metacrine Proposal 1: The Metacrine Merger Proposal
Metacrine stockholders are asked to approve the adoption of the Merger Agreement. Metacrine stockholders should carefully read this joint proxy statement/prospectus in its entirety, including the documents incorporated by reference and the Merger Agreement, for more detailed information concerning the Merger Agreement and the Metacrine merger proposal. For a detailed discussion of the terms of the Merger Agreement and the Merger, see the information about the Merger and the Merger Agreement throughout this joint proxy statement/prospectus, including the information set forth in the section entitled “The Merger Agreement” beginning on page 57 of this joint proxy statement/prospectus. A copy of the Merger Agreement is attached as Annex A to this joint proxy statement/prospectus.
Approval of the Metacrine merger proposal is a condition to completion of the Merger. If the Metacrine merger proposal is not approved, the Merger will not occur. For a detailed discussion of the conditions of the Merger, see “The Merger Agreement—Conditions to Completion of the Merger” beginning on page 72 of this joint proxy statement/prospectus.
Approval of the Metacrine merger proposal requires the affirmative vote of a majority of the outstanding shares of Metacrine's common stock. Failure to vote at the virtual special meeting or vote by proxy at the special meeting, abstentions, and broker non-votes (if any) will have the same effect as a vote against the Metacrine merger proposal. Shares of Metacrine common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If a Metacrine stockholder returns a signed proxy card without indicating voting preferences on such proxy card, the shares of Metacrine common stock represented by that proxy will be counted as present for purposes of determining the presence of a quorum for the Metacrine virtual special meeting and all of such shares will be voted as recommended by the Metacrine Board.
Pursuant to an action by unanimous written consent of the Metacrine Board dated September 5, 2022, which was reaffirmed by the Metacrine Board on October 19, 2022, the Metacrine Board determined that the Merger Agreement and the transactions contemplated thereby were in the best interests of Metacrine and its stockholders, and approved the Merger Agreement and the Merger, the execution of the Merger Agreement and the consummation of the transactions contemplated thereby and declared advisable and recommended that Metacrine’s stockholders adopt the Merger Agreement.
IF YOU ARE A METACRINE STOCKHOLDER, THE METACRINE BOARD
RECOMMENDS THAT YOU VOTE “FOR” THE PROPOSAL TO ADOPT
THE MERGER AGREEMENT.

Metacrine Proposal 2: The Metacrine Adjournment Proposal
This proposal would permit the Metacrine Board to adjourn from time to time the Metacrine virtual special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the Metacrine merger proposal.
Pursuant to the Metacrine bylaws, notice need not be given of any such adjourned meeting if the time and place thereof are announced at the meeting at which adjournment is taken. If the adjournment is for more than 30 days or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the Metacrine virtual special meeting. At any adjourned meeting, any business may be transacted which might have been transacted at the original meeting.
Approval of the Metacrine adjournment proposal requires the holders of Metacrine common stock representing a majority of the votes cast on such matter at the Metacrine virtual special meeting (whether or not a quorum exists). For the Metacrine adjournment proposal, abstentions and broker “non-votes” will have no effect on the outcome of the proposal. Shares of Metacrine common stock represented by properly executed, timely received and unrevoked proxies will be voted in accordance with the instructions indicated thereon. If a Metacrine stockholder returns a signed proxy card without indicating voting preferences on such proxy card, the shares of Metacrine common stock represented by that proxy will be counted as present for purposes of determining the presence of a quorum for the Metacrine virtual special meeting and all of such shares will be voted as recommended by the Metacrine Board.
IF YOU ARE A METACRINE STOCKHOLDER, THE METACRINE BOARD RECOMMENDS
THAT YOU VOTE “FOR” THE PROPOSAL TO PERMIT THE METACRINE BOARD TO
ADJOURN THE METACRINE VIRTUAL SPECIAL MEETING.

TABLE OF CONTENTS

THE MERGER AGREEMENT
The following section summarizes the material provisions of the Merger Agreement, which is included in this joint proxy statement/prospectus as Annex A and is incorporated herein by reference in its entirety. The rights and obligations of Equillium and Metacrine are governed by the express terms and conditions of the Merger Agreement and not by this summary or any other information contained in this joint proxy statement/prospectus. Equillium and Metacrine stockholders are urged to read the Merger Agreement carefully and in its entirety as well as this joint proxy statement/prospectus before making any decisions regarding the Merger, including the adoption by the Metacrine stockholders of the Merger Agreement or the approval by the Equillium stockholders of the issuance of shares of Equillium common stock in connection with the Merger. This summary is qualified in its entirety by reference to the Merger Agreement.
The Merger Agreement, as amended on October 26, 2022 to join Acquisition Sub II as a party, is described in this joint proxy statement/prospectus to provide you with information regarding its terms. The Merger Agreement is not intended to provide any other factual information about Equillium or Metacrine, their respective businesses, or the actual conduct of their respective businesses during the period prior to the consummation of the Merger or the other transactions contemplated therein. The Merger Agreement contains representations and warranties that are the product of negotiations among the parties thereto which were made only for purposes of such agreement and as of specified dates. The assertions embodied in those representations and warranties are subject to qualifications and limitations agreed to by the respective parties and are also qualified in important part by confidential disclosure letters delivered by and to each of Equillium and Metacrine in connection with the Merger Agreement. The representations and warranties may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to stockholders or investors. Information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Equillium’s or Metacrine’s public disclosures.
Accordingly, the representations and warranties and other provisions of the Merger Agreement should not be read alone, but instead should be read together with the information provided elsewhere in this joint proxy statement/prospectus and in the documents incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 141 of this joint proxy statement/prospectus.
Terms of the Merger; Merger Consideration
Pursuant to the Merger Agreement, and in accordance with Delaware law, at the effective time of the Merger, Merger Sub will be merged with and into Metacrine, with Metacrine continuing as a direct wholly owned subsidiary of Equillium.
At the effective time of the Merger, each share of Metacrine common stock issued and outstanding (other than shares held in treasury, if any), will be automatically converted into the right to receive a number of validly issued, fully paid and non-assessable shares of Equillium common stock as determined by applying the Exchange Ratio, which we refer to as the merger consideration.
As used in this joint proxy statement/prospectus, the Exchange Ratio means (x) (a) 125% of Metacrine’s net cash as defined below, or Metacrine Net Cash, as of the closing of the Merger, or the Upfront Merger Consideration, divided by (b) the price per share of Equillium common stock determined based on the 10 day trading volume weighted average price per share of Equillium common stock calculated 10 trading days prior to the closing date of the Merger, provided that in no event will such value of the price per share of Equillium common stock be less than $2.70 per share or greater than $4.50 per share, or the Equillium Stock Price, divided by (y) the aggregate fully diluted shares of Metacrine, or Metacrine’s as defined below, or Aggregate Fully Diluted Shares, subject to adjustment for as a result of any reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, reorganization, subdivision, or other similar transaction. In the event of any reclassification, stock split, reverse stock split, stock dividend, stock distribution, recapitalization, subdivision or other similar transaction with respect to the shares of Metacrine common stock or shares of Equillium common stock prior to the effective time of the Merger, the merger consideration will be equitably adjusted to eliminate the effects of such event on the merger consideration as contemplated by the Merger Agreement.
Metacrine Net Cash means (a) the sum of (i) Metacrine’s and its subsidiaries’ cash and cash equivalents, and (ii) to the extent not already reflected in the immediately foregoing prong (i), the aggregate amount of all
57

TABLE OF CONTENTS

deposits, prepaid expenses, and including short term investments held by Metacrine or its subsidiaries (in each including any interest, earnings or other income earned thereon), in each case as of the anticipated Closing Date, minus (b) the sum of the Metacrine’s short and long term liabilities, including accounts payable and accrued expenses (without duplication of any expenses accounted for below), in each case as of such date and determined in a manner consistent with the manner in which such items were historically determined and in accordance with Metacrine’s audited financial statements and unaudited balance sheet as of June 30, 2022 to the extent consistent with GAAP, minus (c) the amount of all fees and expenses incurred by Metacrine and its subsidiaries in connection with the transactions contemplated by the Merger Agreement, including for the avoidance of doubt transaction expenses incurred by Metacrine and its subsidiaries, to the extent unpaid as of the Closing, minus (d) the cash cost of any unpaid change of control payments or severance, termination or similar payments pursuant to a contract, plan or applicable Law that are or become due to any current or former employee, director or independent contractor of Metacrine and its subsidiaries, or any other third party arising out of, relating to, or in connection with the occurrence of the Closing, minus (e) the cash cost of any paid time off, accrued and unpaid retention payments or other bonuses due to any current or former employee, director or independent contractor of Metacrine and its subsidiaries as of the Closing Date, minus (f) all payroll, employment or other withholding Taxes incurred by Metacrine and its subsidiaries and any affiliate of Metacrine (to the extent paid or to be paid by Metacrine on the behalf of such affiliate) in connection with any payment amounts set forth in clauses (d) or (e) and the exercise of any Metacrine Option on or prior to the Effective Time, minus (g) the cash cost of any unpaid retention payment amounts due under any insurance policy with respect to any legal proceeding against Metacrine or any of its subsidiaries, minus (h) the expected cost and expenses of the aggregate liability of Metacrine or any of its subsidiaries for liabilities arising from legal proceedings, minus (i) notice payments, fines or other payments to be made by Metacrine or any of its subsidiaries in order to terminate any existing agreement to which Metacrine is a party, minus (j) payments up to the unpaid deductible amount under Metacrine’s director and officer insurance reasonably expected to be payable in connection with legal proceedings in effect as of the date of the Merger Agreement or initiated following the date of the Merger Agreement and before the Closing assumed by the insurer or expected to be assumed by the insurer, minus (k) the expected cost, and/or any premium related to the director and officer insurance tail policy, minus (l) the amount of any accounts payable of Metacrine or any of its subsidiaries that are past the original vendor due date as of the anticipated Closing Date, minus (m) the amount of any indebtedness, plus (n) any interest expenses required to be paid by Metacrine under its existing loan and security agreement on or after October 1, 2022 and prior to the Closing Date.
Aggregate Fully Diluted Shares means the aggregate number of shares of Metacrine common stock, but excluding shares of Metacrine common stock held in treasury, that are (a) issued and outstanding immediately prior to the Effective Time; or (b) issuable upon, or subject to, the exercise or settlement of any Metacrine warrants, convertible securities, stock options or other equity awards or other similar securities, in each case as of immediately prior to the Effective Time.
Equillium will not issue fractional shares of Equillium common stock pursuant to the Merger Agreement. Instead, each Metacrine stockholder who otherwise would have been entitled to receive a fraction of a share of Equillium common stock will receive cash in lieu thereof, as provided in the Merger Agreement.
Calculation of Metacrine Net Cash
At least five days prior to the anticipated closing date of the Merger, which date shall be agreed upon by Equillium and Metacrine 10 days prior to the later of (i) the Equillium virtual special meeting and (ii) the Metacrine virtual special meeting, in each case subject to adjournment or postponement, Metacrine shall deliver to Equillium a schedule setting forth a good faith estimated calculation of the Metacrine Net Cash as of the anticipated closing date of the Merger, or the Net Cash Schedule. Within three days after delivery of the Net Cash Schedule, Equillium has the right to dispute any part of the Net Cash Schedule by delivering a written notice identifying in reasonable detail the nature of any proposed revisions to the Net Cash Schedule. If Equillium does not respond within three days after the delivery of the Net Cash Schedule or notifies Metacrine that it has no objections, the Net Cash Schedule shall be final and represent the Metacrine Net Cash.
If Equillium timely disputes the Net Cash Schedule, Equillium and Metacrine shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed upon determination of Metacrine Net Cash. If Equillium and Metacrine are unable to negotiate an agreed upon determination of Metacrine Net Cash, within three days of Equillium delivering a dispute notice to the Net Cash Schedule, Equillium and
58

TABLE OF CONTENTS

Metacrine shall select an independent auditor to resolve any remaining disagreements to the calculation of Metacrine Net Cash. Equillium and Metacrine shall use commercially reasonable efforts to cause the auditor to make its determination within 10 days of after accepting its selection. The determination of the Metacrine Net Cash made by the auditor shall be deemed final for purposes of the Merger Agreement. The fees of the auditor shall be borne by the parties in the same proportion that the disputed amount of Metacrine Net Cash was unsuccessfully disputed by such party based on the total disputed amount of Metacrine Net Cash. The parties shall not be required to determine Metacrine Net Cash again after it is finally determined even if the closing of the Merger occurs after the anticipated closing date of the Merger, except either party may request a re-determination of Metacrine Net Cash if the closing of the Merger is more than five business days after the anticipated closing date of the Merger.
Procedures for Exchanging Metacrine common stock in the Merger
Prior to the effective time of the Merger, the parties will designate American Stock Transfer & Trust Company, LLC, or AST, or if AST is unwilling or unable to serve then such other mutually agreeable bank or trust company to act as the exchange agent in connection with the Merger, or the Exchange Agent. At the Closing, Equillium will issue and cause to be deposited with the Exchange Agent (i) non-certificated shares of Equillium common stock issuable pursuant to the Merger Agreement in book-entry form equal to the aggregate merger consideration (excluding any cash in lieu of fractional shares payable pursuant to the Merger Agreement) and (ii) cash in immediately available funds in an amount sufficient to pay in lieu of fractional shares payable pursuant to the Merger Agreement, in each case, for the sole benefit of the holders of shares of Metacrine common stock.
Upon surrender of stock certificates, if such shares of Metacrine common stock are represented by a stock certificate, accompanied by an executed letter of transmittal and other documents described in the instructions or, in the case of uncertificated shares, an “agent’s message” in customary form, of Metacrine common stock for cancellation, a Metacrine stockholder will receive the following: (i) the share consideration to which such Metacrine stockholder is entitled and (ii) cash in lieu of fractional shares of Equillium common stock, if any. Metacrine stockholders will not receive any fractional shares of Equillium common stock pursuant to the Merger. After the effective time of the Merger, Metacrine will not register any transfers of the shares of Metacrine common stock. Shares of Equillium common stock issued in connection with the Merger will be issued in uncertificated, book-entry form.
After the effective time of the Merger, shares of Metacrine common stock will no longer be issued and outstanding, will be canceled and will cease to exist, and (A) each certificate, if any, that previously represented Metacrine common stock and (B) each book-entry account formerly representing any uncertificated shares of Metacrine common stock will represent only the right to receive the merger consideration as described above. With respect to such shares of Equillium common stock deliverable upon the surrender of Metacrine share certificates, until holders of such Metacrine share certificates have surrendered such stock certificates to the exchange agent for exchange, those holders will not receive dividends or distributions with respect to such shares of Equillium common stock with a record date after the effective time of the Merger.
Equillium stockholders need not take any action with respect to their stock certificates.
Completion of the Merger
The closing of the Merger will take place (a) via electronic exchange of required closing documentation, as soon as reasonably practicable, and in no event later than three business days after the satisfaction or waiver of the conditions to the closing of the Merger have been satisfied or waived (other than conditions that by their nature cannot be satisfied until the closing of the Merger, which shall be required to be so satisfied or waived in accordance with the Merger Agreement upon the closing date of the Merger) or (b) at such other time, date or place as Equillium and Metacrine may agree in writing. The Merger will become effective upon the filing of the certificate of Merger with the Secretary of State of the State of Delaware, in accordance with the laws of Delaware.

TABLE OF CONTENTS

Many of the representations and warranties in the Merger Agreement are qualified by a “knowledge,” “materiality” or “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct, individually or in the aggregate, would, as the case may be, be material or have a material adverse effect). For purposes of the Merger Agreement, a “material adverse effect” means, with respect to a party, any fact, circumstance, effect, change, event or development that, individually or in the aggregate, materially adversely affects or would reasonably be expected to materially adversely affect the business, financial condition or results of operations of a party and its subsidiaries, taken as a whole.
The definition of “material adverse effect” excludes any fact, circumstance, effect, change, event or development to the extent that, either alone or combination, it results from or arises out of:
changes or conditions generally affecting the industries in which such party and any of its subsidiaries operate, except to the extent such fact, circumstance, effect, change, event or development has a materially disproportionate adverse effect on such party and its subsidiaries, taken as a whole, relative to others in such industries in respect of the business conducted in such industries;
general economic or political conditions or securities, credit, financial or other capital markets conditions, in each case in the United States or any foreign jurisdiction, except to the extent such fact, circumstance, effect, change, event or development has a materially disproportionate adverse effect on such party and its subsidiaries, taken as a whole, relative to others in the industries in which such party or any of its subsidiaries operate in respect of the business conducted in such industries;
any failure, in and of itself, by such party to meet any internal or published projections, forecasts, estimates or predictions in respect of revenues, earnings or other financial or operating metrics for any period (it being understood that the facts or occurrences giving rise to or contributing to such failure may be deemed to constitute, or be taken into account in determining whether there has been, or is reasonably expected to be, a material adverse effect);
the public announcement or pendency of the transactions contemplated in the Merger Agreement, including the impact thereof on the relationships, contractual or otherwise, of such party and its subsidiaries with employees, labor unions, suppliers or partners;
any change, in and of itself, in the market price or trading volume of such party’s securities or in its credit ratings (it being understood that the facts or occurrences giving rise to or contributing to such change may be deemed to constitute, or be taken into account in determining whether there has been, or is reasonably expected to be, a material adverse effect);
any change in applicable law, regulation or GAAP (or authoritative interpretation thereof), except to the extent such fact, circumstance, effect, change, event or development has a materially disproportionate adverse effect on such party and its subsidiaries, taken as a whole, relative to others in the industries in which such party and its subsidiaries operate in respect of the business conducted in such industries;
geopolitical conditions, the outbreak or escalation of hostilities, any acts of war (whether or not declared), sabotage or terrorism, or any escalation or worsening of any such acts of war, sabotage or terrorism threatened or underway as of the date of the Merger Agreement, except to the extent such fact, circumstance, effect, change, event or development has a materially disproportionate adverse effect on such party and its subsidiaries, taken as a whole, relative to others in the industries in which such party and any of its subsidiaries operate in respect of the business conducted in such industries;
any hurricane, tornado, flood, earthquake or other natural disaster, except to the extent such fact, circumstance, effect, change, event or development has a materially disproportionate adverse effect on such party and its subsidiaries, taken as a whole, relative to others in the industries in which such party and any of its subsidiaries operate in respect of the business conducted in such industries;
any epidemic, pandemic or disease outbreak (including Covid-19) and any action by a governmental entity in response thereto, except to the extent that such fact, circumstance, effect, change, event or development has a materially disproportionate adverse effect on such party and its subsidiaries;
any litigation arising from allegations of a breach of fiduciary duty or other violation of applicable law relating to the Merger Agreement or the transactions contemplated thereby;

TABLE OF CONTENTS

any adverse effects, adverse events or safety observations or reports of new side effects, adverse events or safety observations with respect to such party’s product candidates that are not reasonably expected to materially affect the likelihood or timing of FDA approval;
any change or modification to any development program of Equillium or its affiliates; or
any taking of any action required pursuant to the Merger Agreement or not required by the Merger Agreement, but in each case taken at the written request of the other party or parties thereto or any action expressly required to be taken under the Merger Agreement.
The representations and warranties contained in the Merger Agreement will not survive the consummation of the Merger, but they form the basis of specified conditions to the parties’ obligations to complete the Merger.
Conduct of Business
Each of Equillium and Metacrine has agreed to certain covenants in the Merger Agreement restricting the conduct of its business between the date of the Merger Agreement and the effective time of the Merger.

See “Risk Factors” at page 30 for a discussion of the risks associated with the exceptions from the above described covenants.
No Solicitation of Alternative Proposals
Each of Metacrine and Equillium has agreed that, from the time of the execution of the Merger Agreement until the earlier of the termination of the Merger Agreement or the consummation of the Merger, it and its subsidiaries will not, and it will cause its and its subsidiaries’ directors and officers not to, and will not direct any of their respective employees, investment bankers, attorneys, accountants and other advisors, agents or representatives, or collectively, along with such directors, officers and employees, representatives, not to, directly or indirectly: (i) solicit, initiate, knowingly induce, knowingly encourage or knowingly facilitate (including by way of granting a waiver under Section 203 of the DGCL) any inquiries or the making of any proposal or offer that constitutes an acquisition proposal or that would reasonably be expected to lead to an acquisition proposal, (ii) participate in any negotiations or discussions or cooperate in any way (except as otherwise permitted under the terms of the Merger Agreement) with any person regarding any proposal the consummation of which would constitute an acquisition proposal, (iii) provide any information or data concerning itself or any of its subsidiaries to any person in connection with any proposal that, if consummated, would constitute an acquisition proposal or for the purpose of soliciting, initiating, inducing, encouraging or facilitating an acquisition proposal; (iv) enter into any binding or nonbinding letter of intent, term sheet, memorandum of understanding, merger agreement, acquisition agreement, agreement in principle, option agreement, joint venture agreement, partnership agreement, lease agreement or other similar agreement with respect an acquisition proposal or any proposal or offer that

could reasonably be expected to lead to an acquisition proposal; (v) adopt, approve, recommend, make any public statement approving or recommending any inquiry, proposal or offer that constitutes an acquisition proposal or that could reasonably be expected to lead to an acquisition proposal (including by approving any transaction, or approving any person becoming an “interested stockholder,” for purposes of Section 203 of the DGCL); take any action or exempt any person (other than Equillium and its subsidiaries) from the restriction on “business combinations” or any similar provision contained in applicable takeover laws or Metacrine’s organizational or other governing documents or (vi) resolve, publicly propose or agree to do any of the foregoing.
The Merger Agreement also requires both Equillium and Metacrine to, and to cause its each of its respective subsidiaries and representatives to, immediately cease and cause to be terminated any and all existing activities, discussions or negotiations with any parties conducted prior to the execution of the Merger Agreement with respect to any acquisition proposal or proposal that could reasonably be expected to lead to an acquisition proposal. As soon as reasonably practicable after the date of the Merger Agreement, Metacrine will deliver a written notice to each person that entered into a confidentiality agreement in anticipation of potentially making an acquisition proposal within the last 30 days, to the effect that Metacrine is ending all discussions and negotiations with such person with respect to any acquisition proposal, effective on the date of the Merger Agreement and requesting the prompt return or destruction of all confidential information previously furnished to such person. Metacrine will additionally take all actions necessary to enforce its rights under the provisions of any “standstill” agreement between Metacrine and any person (other than Equillium), and, subject to the terms of the Merger Agreement.
An “acquisition proposal” with respect to Metacrine means any proposal (other than an offer or proposal made by Equillium or any of its subsidiaries) for (i) any merger, consolidation, share exchange, business combination, issuance of securities, direct or indirect acquisition of securities, recapitalization, tender offer, exchange offer or other similar transaction in which a person or “group” (as defined in the Exchange Act and the rules promulgated thereunder) of persons directly or indirectly acquires, or if consummated in accordance with its terms would acquire, beneficial or record ownership of securities representing more than 20% of the outstanding shares of any class of voting securities of Metacrine; (ii) issuance or acquisition of securities representing more than 20% of the outstanding shares of any class of voting securities of Metacrine; (iii) any direct or indirect sale, lease, exchange, transfer, acquisition or disposition of any assets of Metacrine and of its subsidiaries that constitute or account for (x) more than 20% of the consolidated net revenues, consolidated net income or consolidated book value of Metacrine; or (y) more than 20% of the fair market value of the assets of Metacrine; or (iv) any liquidation or dissolution of Metacrine.
An “acquisition proposal” with respect to Equillium means any proposal (other than an offer or proposal made by Metacrine or any of its subsidiaries) for (i) any merger, consolidation, share exchange, business combination, issuance of securities, direct or indirect acquisition of securities, recapitalization, tender offer, exchange offer or other similar transaction in which a person or “group”(as defined in the Exchange Act and the rules promulgated thereunder) of persons directly or indirectly acquires, or if consummated in accordance with its terms would acquire, beneficial or record ownership of securities representing more than 20% of the outstanding shares of any class of voting securities of Equillium; (ii) issuance or acquisition of securities representing more than 20% of the outstanding shares of any class of voting securities of Parent; (iii) except as permitted pursuant to the terms of the Merger Agreement, any direct or indirect sale, lease, exchange, transfer, acquisition or disposition of any assets of Equillium and its subsidiaries that constitute or account for (x) more than 20% of the consolidated net revenues, consolidated net income or consolidated book value of Equillium; or (y) more than 20% of the fair market value of the consolidated assets of Equillium; or (iv) any liquidation or dissolution of Equillium.
Notwithstanding the restrictions described above, if, prior to obtaining stockholder approval, a party receives an unsolicited, written acquisition proposal that did not result from a breach, in any material respect, of the Merger Agreement from a third party, then such party may (i) contact the third party making such acquisition proposal to clarify the terms and conditions thereof and information them of the terms of the Merger Agreement applicable to such acquisition proposal, (ii) provide access to non-public information regarding such party and its subsidiaries to such third party; provided that such information has previously been available to the other party or is provided to the other party substantially concurrently with the making of such information available to such third party and that, prior to furnishing any such non-public information, such party receives from such third
66

TABLE OF CONTENTS

party an executed confidentiality agreement with terms at least as restrictive in all material respects on such third party as the terms of the confidentiality agreement between Metacrine and Equillium (it being understood that such confidentiality agreement need not prohibit the making or amending of the acquisition proposal) and (iii) participate or engage in any negotiations or discussions with such third party if, and only if, prior to taking any action described in clause (ii) or (iii) above, such party’s board determines in good faith after consultation with outside legal counsel that (A) based on the information then available and after consultation with a financial advisor of nationally recognized reputation that such acquisition proposal constitutes, or would reasonably be expected to result in, a superior proposal and (B) the failure to take such action would reasonably be expected to be inconsistent with the directors’ fiduciary duties under applicable law.
A “superior proposal” means any bona fide, binding, written acquisition proposal on terms which the Metacrine Board or the Equillium Board, as the case may be, determines in its good faith judgment (after consultation with outside legal counsel and an independent financial advisor) would reasonably be expected to be consummated in accordance with its terms (taking into account all legal, financial and regulatory aspects of the proposal and the party making the proposal) and, if consummated, would result in a transaction more favorable to the Metacrine stockholders or Equillium stockholders, as the case may be, from a financial point of view than the Merger (including any changes to the terms of the Merger Agreement made in response to such offer in accordance with the Merger Agreement) and the time likely required to consummate the applicable acquisition proposal; provided that for purposes of the definition of “superior proposal”, the references to “20%” in the definition of “acquisition proposal” will be deemed to references to “50%.”
The Merger Agreement requires each party to notify the other (orally and in writing) promptly (and, in any event, within 24 hours) of, among other things, the receipt of any written or other inquiries, proposals or offers that is or could reasonably be expected to lead to an acquisition proposal, any non-public information requested in connection with such an acquisition proposal or any discussion or negotiation with respect to or that could reasonably be expected to lead to an acquisition proposal (indicating, in such notice, the identity of the potential counterparty and the material terms and conditions of any such proposal or offer, including proposed agreements and other material written communications). In addition, the Merger Agreement requires each party to continue to inform the other of the status of any such proposals or offers and the status of any such discussion or negotiations. The parties further agree that it and its subsidiaries will not enter into any confidentiality agreement with any person subsequent to the date of the Merger Agreement which prohibits either from providing any information to the other party in accordance with the terms of the Merger Agreement or otherwise prohibits such party from complying with its obligations under the Merger Agreement. The parties further agree that it will not provide information to any person pursuant to any confidentiality agreement entered into prior to the date of the Merger Agreement unless such person agrees prior to receipt of such information to waive any provision that would prohibit such party from providing any information to the other party in accordance with the terms of the Merger Agreement or otherwise prohibits such party from complying with its obligations under the terms of the Merger Agreement.
Changes in Board Recommendations
Each of Equillium and Metacrine has agreed that its board of directors and each committee of its board of directions shall not (i) withhold, withdraw, qualify or modify (or publicly propose or resolve to withhold, withdraw, qualify or modify), in any manner adverse to the other party, the recommendation by such board with respect to the transactions contemplated by the Merger Agreement, as applicable, or approve, recommend or otherwise declare advisable (or publicly propose or resolve to approve, recommend or otherwise declare advisable) any applicable acquisition proposal or make or authorize the making of any public statement (oral or written) that has the substantive effect of such a withdrawal, qualification or modification or remove the recommendation by such board from or fail to include the recommendation of the board in this joint proxy statement/prospectus, each such event is referred to as a change in recommendation, (ii) cause Equillium or Metacrine, as the case may be, or any of its respective subsidiaries, to enter into any agreement relating to or that could reasonably be expected to lead to any acquisition proposal or requiring such party (or that would require such party) to abandon, terminate, or fail to consummate the Merger or any other transaction contemplated by the Merger Agreement or that would otherwise materially impede, interfere with or be inconsistent with, the transactions contemplated thereby, or an alternative acquisition agreement.
Notwithstanding the foregoing, each of the Equillium Board and the Metacrine Board may change its recommendation to its respective stockholders (subject to the other party’s rights to match competing proposals
67

TABLE OF CONTENTS

and right to terminate the Merger Agreement following such change in recommendation, as more fully described in the Merger Agreement) in response to a superior proposal or an intervening event if, subject to compliance with other provisions by the applicable company and its representatives, the Equillium Board or the Metacrine Board, as applicable determines in good faith, after consultation with financial advisors of nationally recognized reputation and outside legal counsel, that the failure to take such action would be inconsistent with the applicable directors’ fiduciary duties under applicable law.
An “intervening event” with respect to Metacrine or Equillium means any event or development that has a material effect on either party and its subsidiaries taken as a whole, occurring or arising after the date of the Merger Agreement that (i) was not known to, or reasonably foreseeable by the Metacrine Board, with respect to Metacrine, or by the Equillium Board, with respect to Equillium, prior to the execution of the Merger Agreement, which event, occurrence, fact, condition, change, development or effect becomes known to, or reasonably foreseeable by, such party’s board prior to the receipt of such party’s stockholder approval and (ii) does not relate to (A) an acquisition proposal or (B)(1) any changes in the market price or trading volume of Equillium or Metacrine (it being understood that the cause of such change may be taken into consideration unless otherwise excluded pursuant thereto), (2) Equillium or Metacrine meeting, failing to meet or exceeding published or unpublished revenue or earnings projections, in each case in and of itself (it being understood that the cause of such change may be taken into consideration unless otherwise excluded pursuant hereto), (3) any events or developments relating to such party and its affiliates, (4) any event or development generally affecting the industries in which either party operates or in the economy generally or other general business, financial or market conditions, (5) any change in any applicable Law and (iii) any event or development to the extent directly resulting from the announcement or pendency of, or any actions required to be taken by either party (or refrained to be taken by either party) pursuant to the Merger Agreement or the consummation of the transactions contemplated thereby.
Efforts to Obtain Required Stockholder Votes
Each of Metacrine and Equillium has agreed, subject to the qualifications described above, to use its reasonable best efforts to convene and hold a meeting of its stockholders to consider and vote upon the adoption of the Merger Agreement after the declaration of the Form S-4 of which this joint proxy statement/prospectus forms a part. Each of the Metacrine Board and Equillium Board has approved the Merger Agreement and determined the Merger Agreement and the transactions contemplated thereby, including the Merger, are advisable, fair to and in the best interests of each of Metacrine and Equillium, respectively, and their respective stockholders, and has adopted resolutions directing that the Merger Agreement be submitted to their respective stockholders for their consideration. Notwithstanding the foregoing, (x) if on or before the date (1) the Metacrine stockholders meeting is scheduled to be held, Metacrine reasonably believes that (A) it will not receive proxies representing a sufficient number of shares of Metacrine common stock to adopt Metacrine merger proposal or (B) it will not have enough shares of Metacrine common stock to constitute a quorum, Metacrine has the right to (and, if requested by Equillium, must) on one or more occasions postpone or adjourn the Metacrine stockholders meeting and (2) the Equillium stockholders meeting is scheduled to be held, Equillium reasonably believes that (A) it will not receive proxies representing a sufficient number of shares of Equillium common stock to adopt the Equillium stock issuance proposal or (B) it will not have enough shares of Equillium common stock to constitute a quorum, Equillium has the right to (and if required by Metacrine, must) on one or more occasions postpone or adjourn the Equillium stockholders meeting, and (y) either party may postpone or adjourn such party’s stockholders meeting to allow reasonable additional time for the filing or mailing of any supplemental or amended disclosure that such party has determined, after consultation with outside legal counsel, is reasonably likely to be required under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by such party’s stockholders prior to the such party’s special meeting, as long as such party’s special meeting is not adjourned or postponed for more than an aggregate of 15 calendar days in connection with any such postponements or adjournments pursuant to either or both of the preceding clauses (x) and (y).
Notwithstanding any Metacrine change in recommendation, Metacrine shall submit the Merger Agreement to its stockholders for adoption at the Metacrine stockholders meeting unless the Merger Agreement is terminated in accordance with its terms prior to such meeting. Without the prior written consent of Equillium, the adoption of the Merger Agreement shall be the only matter (other than matters of procedure and matters required by law to be voted on by Metacrine’s stockholders in connection with the adoption of the Merger Agreement and the transactions contemplated thereby) that Metacrine shall propose to be acted on by its stockholders at the Metacrine stockholders meeting.
68

TABLE OF CONTENTS

Notwithstanding any Equillium change in recommendation, Equillium shall seek the Equillium stockholder approval for the Equillium stock issuance at the Equillium stockholders meeting unless the Merger Agreement is terminated in accordance with its terms prior to such meeting. Without the prior written consent of Metacrine, the Equillium stock issuance shall be the only matter (other than matters of procedure and matters required by law to be voted on by Metacrine’s stockholders in connection with the approval of the issuance of shares of Equillium common stock) that Equillium shall propose to be acted on by its stockholders at the Equillium stockholders meeting.
Efforts to Complete the Merger
Equillium and Metacrine have each agreed to cooperate with each other and use, and to cause their respective subsidiaries to use, their respective reasonable best efforts to take or cause to be taken all actions necessary to consummate the Merger and the other transactions contemplated by the Merger Agreement, including making all filings (if any) and give all necessary notices, obtain necessary consents (if any) required to be obtained in connection with the Merger or any other transactions contemplated thereby, and lift any restraint, injunction or other legal bar to the Merger. Notwithstanding the foregoing, neither party will have any obligation under the Merger Agreement to divest or agree to divest any of its respective material businesses, material product lines or material assets, or take or agree to take (or cause its subsidiaries to take or agree to take) any material limitation or material restriction on any of its respective material businesses, material product lines or material assets and neither party will do any of the foregoing without the prior consent of the other parties.
Access; Consultation
Upon reasonable notice, and except as may otherwise be required by applicable law, each of the Equillium and Metacrine will and will cause each of its subsidiaries to, afford the other party’s representatives reasonable access (at the requesting party’s cost) under the supervision of appropriate personnel of the other party, during normal business hours during the period prior to the Effective Time, to the other party’s, and each of its subsidiaries’ employees, properties, assets, books, records and contracts and, during such period, each of Metacrine and Equillium will and will cause each of its subsidiaries to, furnish promptly to the other all information concerning its or any of its subsidiaries’ capital stock, business and personnel as may reasonably be requested by the other; provided, that the foregoing shall require neither the Equillium nor Metacrine to permit any invasive sampling or testing or to disclose any information to the extent that (i) in the reasonable good faith judgment of such party, any applicable law requires such party or its subsidiaries to restrict or prohibit access to any such properties or information, (ii) in the reasonable good faith judgment of such party, the information is subject to confidentiality obligations to a third party or (iii) disclosure of any such information or document would result in the loss of attorney-client privilege; provided, further that with respect to clauses (i) through (iii), Equillium or Metacrine, as applicable, shall use its commercially reasonable efforts to (1) obtain the required consent of any such third party to provide such inspection or disclosure, (2) develop an alternative to providing such information so as to address such matters that is reasonably acceptable to Equillium and Metacrine and (3) in the case of clauses (i) and (iii), implement appropriate and mutually agreeable measures to permit the disclosure of such information in a manner to remove the basis for the objection, including by arrangement of appropriate clean room procedures, redaction or entry into a customary joint defense agreement with respect to any information to be so provided, if the parties determine that doing so would reasonably permit the disclosure of such information without violating applicable law or jeopardizing such privilege. Any investigation will be conducted in such a manner as not to interfere unreasonably with the conduct of the business of the other party. All requests for information will be directed in writing to an executive officer of Equillium or Metacrine, as applicable, or such person as may be designated by any such executive officer.
Indemnification and Insurance
The Merger Agreement requires that all rights to indemnification by the Company existing in favor of those persons who are current or former directors and officers of Metacrine, and any person becomes a director or officer of Metacrine prior to the effective time of the Merger for their acts and omissions as directors and officers of Metacrine occurring prior to the effective, as provided in Metacrine’s amended and restated certificate of incorporation and amended and restated bylaws and as provided in any indemnification agreements between Metacrine and such officer or director (as in effect as of the date of the Merger Agreement, shall survive the Merger and be observed, honored and fulfilled by the surviving company and its subsidiaries to the fullest extent
69

TABLE OF CONTENTS

permitted by law for a period of six year from the date the Merger becomes effective, or the Indemnification Period. During the Indemnification Period, the surviving company and its subsidiaries (and Equillium will cause the surviving company and its subsidiaries to) ensure that the organizational documents of the surviving company and its subsidiaries contain provisions with respect to indemnification, exculpation and the advancement of expenses that are at least as favorable as the indemnification, exculpation and advancement of expenses provisions in Metacrine’s organization documents on the date of the Merger Agreement. During the Indemnification Period or such period in which a party is asserting a claim for indemnification pursuant to the foregoing, whichever is long, the provision of the surviving corporation’s and its subsidiaries’ organization documents may not be repealed, amended or otherwise modified in any manner adverse to the indemnified party, except as required by law.
Without limitation the foregoing and without expanding (1) the obligations of Equillium and its affiliates, or (2) the rights of any indemnified person under Metacrine’s organization documents or any indemnification agreement between Metacrine and the indemnified person in effect as of the date of the Merger Agreement, during the Indemnification Period, the surviving corporation will indemnify and hold harmless each indemnified person from and against any costs, fees and expenses (including the advancement of attorney’s fees and investigation expenses), judgments, fined, losses, claims, damages, liabilities and amounts paid in settlement or compromise in connection with any legal proceeding to the extent such proceeding arises out of or pertains to (i) any actual or alleged action or omission in such indemnified person’s capacity as a director, officer, employee or agent of Metacrine or any of its subsidiaries or other affiliates; and (ii) the Merger. If any indemnified person delivers notice of a claim for indemnification, then the claim will survive the Indemnification Period until it is fully and finally resolved.
The Merger Agreement requires Metacrine to purchase a six-year “tail” prepaid officers’ and directors’ liability insurance policy prior to the effective time of the Merger with benefits and levels of coverage at least as favorable as Metacrine’s existing policies with respect to matters existing or occurring at or prior to the effective time of the Merger for an amount not to exceed 300% of Metacrine’s current annual premiums. Such amount will be reflected in Metacrine’s net cash. The surviving corporation will (and Equillium will cause the surviving corporation to) maintain the tail policy in full force and effect and continue to honor its obligations thereunder for so long as the tail policy is in full force and effect.
Treatment of Metacrine Equity Awards and Warrants
Treatment of Restricted Stock Unit Awards. At the effective time of the Merger, each Metacrine RSU, whether vested or unvested, other than Metacrine RSUs held by any former employee, former service provider or director of Metacrine, will be assumed by Equillium and converted into an assumed RSU equal to the product of (a) the number of shares of Metacrine common stock subject to such Metacrine RSU and (b) the Exchange Ratio (with any fractional shares rounded down to the nearest whole share). Except for the change to the number and type of shares, each assumed RSU will be subject to the same terms and conditions, including vesting, as were applicable to such Metacrine RSU prior to the Merger. At the effective time of the Merger, (a) each outstanding unvested Metacrine RSU held by a former employee, former service provider or director of Metacrine will be cancelled without the payment of any consideration and (b) each outstanding vested and unexercised Metacrine RSU held by a former employee, former service provider or director of Metacrine will be cancelled and converted into a right to receive a number of fully-vested shares of Equillium common stock equal to the product of (a) the number of shares of Metacrine common stock subject to such Metacrine RSU and (b) the Exchange Ratio (with any fractional shares rounded down to the nearest whole share).
Treatment of Stock Options. At the effective time of the Merger, each Metacrine option, whether vested or unvested, other than any Metacrine option held by any former employee, former service provider or director of Metacrine, will be assumed by Equillium and converted into an adjusted option equal to the product of (a) the number of shares of Metacrine common stock subject to such Metacrine option and (b) the Exchange Ratio (rounded down to the nearest whole share). The per share exercise price of each adjusted option will be equal to (i) the per share exercise price of such Metacrine option immediately prior to the Merger divided by (ii) the Exchange Ratio (with the resulting price per share rounded up to the nearest whole cent). Except for the changes made to the number and type of shares and the exercise price, each adjusted option will be subject to the same terms and conditions, including vesting, as were applicable to such Metacrine option immediately prior to the Merger. At the effective time of the Merger, each unvested Metacrine option that is outstanding and unexercised as of immediately prior to such time and held by a former employee, former service provider or director of

Metacrine will be cancelled without the payment of any consideration, and each vested Metacrine option that is outstanding and unexercised as of immediately prior to such time and held by a former employee, former service provider or director of Metacrine will be cancelled and converted into a right to receive a number of shares of Equillium common stock equal to the product of (x) the number of shares of Metacrine common stock subject to such Metacrine option multiplied by the excess, if any, of (1) the Metacrine Share Value over (2) the per share exercise price for shares subject to such Metacrine option, divided by (y) the Metacrine Share Value, multiplied by (z) the Exchange Ratio (rounded down to the nearest whole share).
Treatment of Warrants. At the effective time of the Merger, each Metacrine Warrant that is outstanding and unexercised immediately prior to the closing of the Merger will be automatically substituted into a warrant to purchase the number of shares of Equillium common stock equal to the product obtained by multiplying (i) the number of shares of Metacrine common stock subject to the Metacrine Warrant immediately prior to the closing of the Merger by (ii) the Exchange Ratio (rounding up to the nearest whole share). Each Metacrine Warrant will have an exercise price per share of Equillium common stock equal to (i) the exercise price per share provided in the Metacrine Warrant immediately prior to the closing of the Merger divided by (ii) the Exchange Ratio.
Treatment of ESPP. Following the date of the Merger Agreement, Metacrine has taken actions with respect to the ESPP to provide that with respect to the current purchase period, (i) no employee who is not a participant in the ESPP as of the date of the Merger Agreement may become a participant in the ESPP, and (ii) no employee participating in the current purchase period may increase his or her payroll contribution rate pursuant to the ESPP from the rate in effect immediately prior to the date of the Merger Agreement, except as required by applicable law.

TABLE OF CONTENTS

THE MERGER
This section and the section entitled “The Merger Agreement” describe the material aspects of the Merger, including the Merger Agreement. While Equillium and Metacrine believe that the following description covers the material terms of the Merger, the description may not contain all of the information that is important to you. Equillium and Metacrine encourage you to read carefully this entire joint proxy statement/prospectus, including the Merger Agreement attached to this joint proxy statement/prospectus as Annex A, for a more complete understanding of the Merger.
Background of the Merger
The following chronology summarizes the key meetings and events that led to the signing of the Merger Agreement. This chronology does not purport to catalog every conversation of or among the Metacrine Board, the Equillium Board, their respective representatives, or other parties.
Over the years, in the ordinary course from time to time, the boards of directors and management teams of Metacrine and Equillium have each separately evaluated and considered a variety of financial and strategic opportunities for their respective companies as part of their respective long-term strategies to enhance value for their stockholders, including potential acquisitions, divestitures, business combinations and other transactions.
As part of the ongoing consideration and evaluation of its long-term prospects and strategies, each of the Metacrine Board and Equillium Board frequently review, with Metacrine management and Equillium management, respectively, strategic and financial alternatives in light of developments in Metacrine’s and Equillium’s respective business, the competitive landscape, the economy generally and financial markets, all with the goal of enhancing value for their respective stockholders and making a positive impact in patients’ lives. As part of this process, from time to time, each of Metacrine’s management and Equillium’s management has engaged in business development and/or strategic discussions with industry participants. This includes contacts with numerous companies regarding potential global and regional partnerships, as well as a number of discussions with companies about strategic transactions.
Metacrine had been developing a farnesoid X receptor, or FXR, agonist, MET409, for the treatment of non-alcoholic steatohepatitis, or NASH, a liver disease characterized by excess liver fat, inflammation and fibrosis. Given interim clinical data from October 2021 relating to Metacrine’s programs relative to competing programs, reduced investor sentiment in NASH, and the significant resources required to pursue further development in NASH, Metacrine elected to discontinue future development of its FXR program in NASH in November 2021 while prioritizing its resources and efforts toward the development of MET642 for the treatment of Ulcerative Colitis, or UC, one of the two primary types of Inflammatory Bowel Disease, or IBD. Metacrine was also developing small molecule inhibitors of hydroxysteroid dehydrogenase 17β13, or HSD17β13, for the treatment of NASH. HSD17β13 is a genetically validated target for advanced liver disease.
In December 2021, after considering the cash constraints of Metacrine, the Metacrine Board directed Metacrine management to pursue a potential license partner, particularly in the gastrointestinal space, to advance MET642 and provide capital to the program. Certain members of the Metacrine Board and Metacrine management reached out to a significant number of potential partners, including international parties, focusing on the gastrointestinal space. Little interest was seen in the program, however, one large pharmaceutical company, a leader in the gastrointestinal space, or the Potential Licensing Partner, did engage in further discussions and negotiations with Metacrine management. Metacrine and the Potential Licensing Partner engaged in further discussions and negotiations between October 2021 and August 2022.
On December 2, 2021, Metacrine began a process of evaluating a number of potential strategic alternatives. Over the course of this review of potential strategic alternatives, Metacrine, with the assistance of MTS, contacted or had discussion with 18 companies regarding a potential merger, acquisition or strategic partnership, executed confidential disclosure agreements, or CDAs, with nine companies, and engaged with six companies by either providing or receiving a preliminary proposal. None of the CDAs included a standstill provision or a don’t ask, don’t waive clause. Out of this review, five leading merger candidates emerged: Party A, Party B, Party C, Party D and Equillium.
On December 16, 2021, Preston Klassen, President and Chief Executive Officer of Metacrine, had an initial telephonic conversation with the Chief Executive Officer of Party A regarding a potential strategic transaction.
On December 16, 2021, Metacrine and Party A executed a mutual CDA.

TABLE OF CONTENTS

On December 21, 2021, the Metacrine Board met by video conference to discuss amongst other things its cash burn rate. The Metacrine Board concluded that without a strategic partner it could no longer afford to continue spending cash at the same rate on research and development. In this context, the Metacrine Board approved a corporate restructuring plan, that resulted in the reduction of approximately 50% of Metacrine’s workforce, primarily consisting of Metacrine’s research organization, which consequently resulted in the discontinuation of its hydroxysteroid dehydrogenase, or HSD program.
Commencing in January 2022, Metacrine engaged strategic and financial advisors to, among other things, assist Metacrine in evaluating the companies in its deal pipeline and engaging with a subset of the companies Metacrine and its advisors determined to be of significant interest. In the period from December 2, 2021 through September 6, 2022 the price of Metacrine’s stock on Nasdaq ranged from $1.650 to $0.365 per share and from January 1, 2022 through September 6, 2022, from $0.70 to $0.365 per share.
On January 11, 2022, the Metacrine Board met by video conference and authorized management to negotiate and execute an engagement letter with MTS Partners to serve as Metacrine’s financial advisor because it is nationally recognized in the healthcare industry as having investment banking professionals with significant experience in healthcare investment banking and merger and acquisition transactions, including transactions similar to the Merger.
On January 14, 2022, Metacrine executed an engagement letter with MTS Partners.
On January 18, 2022, Metacrine and Party A held a mutual telephonic due diligence call.
On January 20, 2022, Dr. Klassen, Trisha Millican, then-Chief Financial Officer of Metacrine and Michael York, Chief Business Officer of Metacrine met with representatives of MTS Partners to discuss industry trends and review a list of potential strategic partners for Metacrine with a focus on biopharmaceutical companies in the gastrointestinal and liver disease spaces. The meeting included a discussion regarding planning, timelines and strategies for a potential merger or other business combination involving Metacrine.
Also on January 20, 2022, Mr. York had a telephonic conversation with Daniel Bradbury, Executive Chairman of the Equillium board to discuss strategy in the NASH space and the strategic rationale for a potential combination between Equillium and Metacrine. Mr. York and Mr. Bradbury agreed to continue discussing a potential combination.
Between January 21, 2022 and February 16, 2022, certain members of the Metacrine Board, certain members of the Party A board of directors, Metacrine management and Party A management had conversations to discuss amongst other things: the companies’ respective strategies; financials; drug portfolios; development programs and costs and strategies for clinical trials along with an integrated development plan and budget across the entities, including timing of data catalysts and strategies for financing the integrated development plan; potential deal construct for the merger between Metacrine and Party A along with a proposed valuation for Metacrine; the implied ownership split and exchange ratio for Metacrine in the post-closing combined company; the possibility of utilizing contingent value rights, or CVR, to pass a portion of the value received to the post-closing combined company from any transaction or partnership with the Potential Licensing Partner to the Metacrine stockholders; and the strategic rationale for a potential merger between Metacrine and Party A.
Between January 25, 2022 and February 17, 2022, Metacrine management and certain members of the boards of directors of each of Metacrine and Equillium held in person meetings to discuss amongst other things: the companies’ respective strategies; financials; drug portfolios; development programs and costs and strategies for clinical trials along with an integrated development plan and budget across the entities, including timing of data catalysts and strategies for financing the integrated development plan; potential deal construct for the merger between Metacrine and Equillium along with a proposed valuation for Metacrine; the implied ownership split and exchange ratio for Metacrine in the post-closing combined company; the possibility of utilizing CVRs as part of the consideration; and the strategic rationale for a potential merger between Metacrine and Equillium.
On February 7, 2022, the Strategy and Scientific Review Committee of the Metacrine Board met by video conference with Metacrine management and representatives of MTS Partners present. Metacrine management detailed the strategic conversations to date with Equillium and Party A, including terms each of the potential offers being discussed, the prospective potential value of Metacrine under each offer, the prospects of the
78

TABLE OF CONTENTS

post-closing combined company under each of the offers and the financials of each of Party A and Equillium. Representatives of MTS Partners advised the Metacrine Board and Metacrine management of merger comparables. In whatever offer was received, the importance of receiving a premium to net cash was discussed.
On February 11, 2022, the Equillium Board met via video conference. At the meeting, management provided an update on discussions with respect to the proposed Merger. Based on the current market trends and the potential synergies, the Equillium Board encouraged Equillium’s management team to continue exploring the potential Merger.
On February 16, 2022, Dr. Klassen sent an email to Bruce Steel, CEO of Equillium, that gave guidance as to preferred deal terms, including directional guidance that Metacrine was seeking a premium to the net cash estimate of $29 million which had previously been communicated to Equillium, and the importance of utilizing CVRs to capture value for Metacrine’s clinical development candidate MET642 as part of the consideration.
Also on February 16, 2022, representatives of MTS Partners on behalf of Metacrine reached out to Party A to let them know that Metacrine would be receptive to receiving a proposal from Party A for a merger between the two companies.
On February 17, 2022, Metacrine received a non-binding proposal from Equillium proposing a merger of the two entities. Equillium’s proposal was an all-stock transaction that valued Metacrine at approximately $28 million and valued the post-closing combined company at approximately $144 million. Under Equillium’s proposal at closing in exchange for all of Metacrine’s outstanding common stock, Equillium would cause to be issued a number of shares of its common stock equal to the lesser of (i) 19.99% of its outstanding capital stock as determined in accordance with the Nasdaq Listing Rules, and (ii) $30 million divided by a per share price based on Equillium common stock’s trailing 10 day VWAP, which represented a premium of approximately 48% over the closing price of Metacrine’s stock on February 17, 2022, which was $0.462. Also included in the proposal were CVRs to be paid in cash to the Metacrine stockholders, totaling up to a potential of $272.5 million, upon achievement of milestones with respect to Metacrine’s clinical development candidate MET642.
On February 18, 2022, Metacrine received a non-binding proposal from Party A proposing a merger of the two entities. Party A’s proposal was for an all-stock transaction that valued Metacrine at $40 million, Party A at $150 million and the post-closing combined company at $220 million after taking into account a $30 million public investment in private equity, or PIPE, to be conducted concurrently with the closing of the merger, resulting in an ownership split of 18.2% of the post-closing combined company for Metacrine, 68.2% for Party A and 13.6% for investors in the PIPE.
Later that day the Metacrine Board met by video conference, with Metacrine management and representatives of MTS Partners present to discuss the Party A and Equillium offers. The Metacrine Board discussed the fact that Party A’s offer did not include CVRs with respect to Metacrine assets, something the Metacrine Board thought was important to maximize value to the Metacrine stockholders and that the Metacrine ownership split in the Party A offer was too low. The Metacrine Board instructed Metacrine Management to go back and push for CVRs to Metacrine stockholders and a higher Metacrine post-closing ownership split with Party A. The Metacrine Board also instructed MTS Partners to gauge interest from the Potential Licensing Partner discussing a potential merger between the Potential Licensing Partner and Metacrine.
Later that day representatives of MTS Partners called the Potential Licensing Partner to gauge their interest in pursuing a potential merger between the Potential Licensing Partner and Metacrine. The Potential Licensing Partner agreed to consider and revert to the Metacrine team.
On February 27, 2022, representatives of MTS Partners on behalf of Metacrine had a telephonic conversation with Party A and MTS Partners relayed: that the Metacrine Board wanted Metacrine to have a 30% ownership of the post-closing combined company and that the inclusion of CVRs to Metacrine stockholders was an important component to any offer.
On February 28, 2022, Metacrine received a revised non-binding proposal in email format from Party A for an all-stock transaction valuing Metacrine at $50 million and Party A at $150 million, resulting in an ownership split of 27% of the post-closing combined company for Metacrine and 73% for Party A, prior to the $30 million

PIPE to be conducted concurrently with the closing of the merger. The proposal included CVRs payable to Metacrine stockholders. Following the receipt of the revised proposal from Party A, the Metacrine Board met by video conference with Metacrine management present, and discussed the terms of a potential merger between Metacrine and Party A.
On March 1, 2022, Dr. Klassen had a telephonic conversation with Mr. Steel and informed Mr. Steel that Metacrine was considering multiple offers. Dr. Klassen indicated that Metacrine management would meet with the Metacrine Board in the next week to discuss the respective terms of the Equillium offer and another offer.
On March 2, 2022, Mr. Steel sent Dr. Klassen an email with a revised offer that Mr. Steel indicated was Equillium’s best and final offer and would expire on March 4, 2022, at which point if the offer was not accepted, then Equillium would withdraw from Metacrine’s process. Equillium’s offer was an all-stock transaction that valued Metacrine at $37.5 million. At closing in exchange for all of Metacrine’s outstanding equity securities (on a fully diluted basis), Equillium would issue a number of shares of its common stock equal to $37.5 million divided by a per share price equal to the trailing 10-day VWAP of Metacrine’s share price, calculated 10 trading days prior to closing. Also included in the proposal were CVRs to be paid in cash to the Metacrine stockholders, totaling up to a potential of $22.5 million, upon achievement of milestones with Metacrine’s clinical development candidate MET642.
On March 4, 2022, the Metacrine Board met by video conference with the Metacrine management team and representatives from Wilson Sonsini Goodrich and Rosati, P.C., or Wilson Sonsini, legal counsel to Metacrine in connection with the proposed Merger and present to discuss the Equillium best and final offer. The Metacrine Board concluded that Equillium’s best and final offer was lower than Party A’s offer and did not provide enough value to Metacrine stockholders. As a result, the Metacrine Board instructed Metacrine management to (i) let the Equillium best and final offer lapse and (ii) to focus on negotiating with Party A.
Also on March 4, 2022, representatives of MTS Partners on behalf of Metacrine requested that Party A send a formal letter documenting their revised offer including details on the PIPE and CVR milestones.
Additionally, the Potential Licensing Partner called representatives of MTS Partners to inform them that the Potential Licensing Partner was not interested in pursuing a merger or other acquisition with Metacrine.
On March 7, 2022, Metacrine received a formal written revised non-binding proposal from Party A proposing a merger of the two entities in an all-stock transaction. The valuation and ownership splits were unchanged from the February 28, 2022 email proposal, however, the CVRs payable to Metacrine stockholders were updated with the following terms: if a licensing or partnership deal was signed in 2022 Metacrine stockholders would receive 100% of any up front proceeds (less any related clinical trial costs) and 70% of all future proceeds; if a licensing or partnership deal was signed in 2023 Metacrine stockholders would receive 50% of any up front proceeds (less any related clinical trial costs) and 50% of all future proceeds; and if a licensing or partnership deal was signed in 2024 Metacrine stockholders would receive 25% of any up front proceeds (less any related clinical trial costs) and 25% of all future proceeds.
On March 9, 2022, Party A informed representatives of MTS Partners that their existing investors would commit to a $30 million PIPE concurrently with the closing of the merger between Metacrine and Party A and that Party A was planning to ask for a 30-day exclusivity period to negotiate such potential merger.
On March 10, 2022, Metacrine received a 30-day exclusivity proposal from Party A.
From March 13, 2022 to April 2, 2022, Mr. Steel and Dr. Klassen continued their discussion, during which Dr. Klassen confirmed that Metacrine was still actively engaging with other parties, and that there was potential interest in the proposed Merger, but not on the terms contained in Equillium’s indicated best and final offer from March 2, 2022.
From March 14, 2022 to April 11, 2022, certain members of the Metacrine Board, Metacrine management and Party A held a series of telephonic due diligence calls.
On March 16, 2022, representatives of MTS Partners on behalf of Metacrine and Party A had a telephonic conversation during which MTS Partners expressed concern about the PIPE together with post-closing combined company cash in Party A’s proposal being insufficient to fund operations on an ongoing basis.

TABLE OF CONTENTS

On March 17, 2022, Mr. Steel and Dr. Klassen had a telephonic conversation where Dr. Klassen relayed that the Metacrine Board and Metacrine management felt that the merger of Equillium and Metacrine was a potentially synergistic transaction. Dr. Klassen explained that Equillium’s offer was below another offer, and Metacrine management and the Metacrine Board believed that the Equillium offer needed additional economic incentives to be considered superior to the alternative offer. For all these reasons Metacrine was not prepared to proceed into exclusivity with Equillium based on the then proposed offer.
On March 23, 2022, Metacrine management and representatives of MTS Partners had a telephonic conversation to discuss the merger between Metacrine and Party A and the amount of cash that the post-closing combined company would have to fund operations on an ongoing basis.
On March 24, 2022, the Metacrine Board met by video conference with Metacrine management present. Metacrine management shared the post-closing combined company cash flow analysis under the current Party A proposal for a merger between Metacrine and Party A and the Metacrine Board concluded that in such a scenario the post-closing combined company would have insufficient cash to fund operations on an ongoing basis. There was also discussion about the pause in the merger discussions with Equillium after Equillium presented a “best and final” offer that was lower than Party A’s offer. Metacrine management believed that the telephonic conversation between Mr. Steel and Dr. Klassen on March 17, 2022 showed there was still interest from both sides in further engagement, however, there was no significant shift in Equillium’s offer. The Metacrine Board instructed Metacrine management to let Party A know that there was a low likelihood that Metacrine would continue discussions with Party A, to restart discussions with Equillium and to engage with other potential merger candidates including Party B.
Later that day Metacrine management notified Party A that there was a low likelihood that Metacrine would be continuing discussions with Party A.
On March 25, 2022, Metacrine management had an initial telephonic conversation with the management team of Party B regarding a potential strategic transaction. Both sides agreed to execute a mutual CDA.
On March 27, 2022, Metacrine and Party B executed a mutual CDA.
On March 30, 2022, Metacrine and Party B held a mutual telephonic due diligence call.
On April 1, 2022, representatives of MTS Partners on behalf of Metacrine had a telephonic conversation with Party B to discuss Party B’s feedback from the preliminary due diligence call, Party B’s interest in moving forward and Party B’s ability to quickly present terms for a potential strategic transaction with Metacrine. Party B expressed an interest in moving forward.
On April 4, 2022, Metacrine received an initial non-binding proposal from Party B proposing a merger of the two entities. Party B’s proposal was for an all-stock transaction, resulting in an ownership split of 15-20% of the post-closing combined company for Metacrine and 80-85% for Party B, at a post-closing combined company value of $42.4 million to $60 million. The initial non-binding proposal also indicated that if Metacrine’s compounds were licensed or otherwise monetized within two years of the merger closing, Metacrine stockholders would be entitled to receive in the form of CVRs, either 50% of the proceeds from milestone payments to Party B or 10-12% of any agreed to upfront licensing fees and pre-commercial milestones paid to Party B plus one-half warrant for each share with a cash exercise price at a 50% premium.
On April 7, 2022, the Metacrine Board met by video conference and discussed the positioning of the FXR in the portfolio of two potential merger options, Equillium and Party B. The Metacrine Board also discussed staffing and other considerations in a scenario where no transaction was contemplated and Metacrine would continue to operate as a standalone entity, or the standalone path.
On April 12, 2022, Metacrine management delivered a counter-proposal to Party B on a telephonic call with the management of Party B. Metacrine proposed a post-closing ownership split of 20% for Metacrine and 80% for Party B. Metacrine also proposed that if any Metacrine assets were partnered, Metacrine stockholders would receive a share of pre-commercial milestone payments (not research and development funding payments) in the form of CVRs, depending on licensing or partnership deal signing time, as follows: if Metacrine’s products were licensed or otherwise monetized in 2022 Metacrine stockholders would receive 70%; if Metacrine’s products were licensed or otherwise monetized in 2023 Metacrine stockholders would receive 50%; and if Metacrine’s products were licensed or otherwise monetized after 2023 Metacrine stockholders would receive 20%.

TABLE OF CONTENTS

On April 13, 2022, representatives of MTS Partners had a telephonic conversation with Party B, where Party B indicated that it was interested in moving forward with a Metacrine transaction, however its board felt that Metacrine’s proposal on the CVR percentage was too high. Party B asked for additional information in order to prepare a counter-offer. The representatives of MTS Partners informed Party B that Metacrine needed time to review its own understanding of the terms of a potential merger between Metacrine and Party B and would then set up a call with Party B.
Also on April 13, 2022, following significant diligence and discussion, the Potential Licensing Partner proposed licensing terms to Metacrine, including certain upfront payments, option fees and milestone fees. Metacrine and the Potential Licensing Partner further negotiated the terms through July 2022.
On April 14, 2022, the Metacrine Board met by video conference with Metacrine management present. Metacrine management updated the Metacrine Board regarding Party B and a new company, Party C, that was potentially entering into the merger discussions and additional considerations in the merger scenario versus the standalone path. Metacrine management and the Metacrine Board continued to examine both the merger and standalone paths.
On April 21, 2022, the Metacrine Board met by video conference with Metacrine management present. Management recommended that the best path for Metacrine stockholders was a merger that allowed forward progress on and monetized a partnered FXR program. Among other things, there was discussion of strategic transactions, including those with Party B and Party C and licensing terms with the Potential Licensing Partner. The Metacrine Board determined that Metacrine should focus on the merger path rather than the standalone path with a goal of finding a merger partner by May 5, 2022.
Also on April 21, Metacrine and Party C held mutual telephonic due diligence calls.
On April 25, Metacrine received a non-binding proposal from Party C proposing a merger of the two entities in an all-stock transaction. Party C’s proposal valued Metacrine at $45 million and Party C at $160 million, resulting in an ownership split of 22% of the post-closing combined company for Metacrine and 78% for Party C. Party C’s proposal included CVRs to Metacrine stockholders for 80% of the economics of MET642.
On April 28, 2022, the Metacrine Board met by video conference to discuss the non-binding proposals from Party B and Party C along with diligence next steps. The Metacrine Board instructed Metacrine management to further negotiate with Party C.
On April 29, 2022, Metacrine management and management of Party C held a telephonic conversation and Metacrine management delivered a counter-proposal to Party C with an ownership split of 27.5% of the post-closing combined company for Metacrine and 72.5% for Party C.
On May 2, 2022, Metacrine received a revised non-binding proposal from Party C, valuing Metacrine at $53 million and Party C at $160 million, resulting in an ownership split of 24% of the post-closing combined company for Metacrine and 74% for Party C.
On May 4, 2022, Metacrine received a revised non-binding proposal from Party B proposing a merger of the two entities. Party B’s revised proposal was for an all-stock transaction, resulting in an ownership split of 20% of the post-closing combined company for Metacrine plus one-half warrant for each share with a cash exercise price at a 50% premium to the deal price and 80% for Party B, at a post-closing combined company value of approximately $60 million. The revised non-binding proposal indicated that if Metacrine’s MET642 drug candidate advanced to a signed option agreement including certain payment terms, Metacrine stockholders would receive a share of pre-commercial milestone payments (which was not to include not research and development funding payments) in the form of CVRs, depending on signing time for the licensing or partnership deal, as follows: if a licensing or partnership deal is signed within six month of the merger closing, Metacrine stockholders would receive 50% of proceeds from such milestone payments; if a licensing or partnership deal has not been signed within six months of the merger closing, the percent due Metacrine stockholders would be decreased by 40% to 30% of the proceeds from such milestone payments; if a licensing or partnership deal has not been signed within one year of the merger closing the percent due Metacrine stockholders would be decreased by 60% to 20% of the proceeds from such milestone payments; if a licensing or partnership deal has not been signed within 18 months of the merger closing the percent due Metacrine stockholders would be

decreased by 80% to 10% of the proceeds from such milestone payments; and if a licensing or partnership deal has not been signed within two years of the merger closing the percent due Metacrine stockholders would be decreased by 100% and no share of the milestone payment would be received by Metacrine stockholders.
On May 10, 2022, the Metacrine Board met by video conference with Metacrine management present to discuss the proposals from Party B and Party C. Based on its findings through the due diligence process Metacrine management indicated and the Metacrine Board agreed that the path to regulatory approval for Party C’s products was too high risk. In light of this fact, the Metacrine Board instructed Metacrine management to let Party C know that Metacrine would not be further pursuing a transaction with Party C. The Metacrine Board authorized management to negotiate further with Party B and also to reach out to Equillium to gauge their interest in submitting another proposal for a merger with Metacrine.
Later that day, representatives of MTS Partners on behalf of Metacrine, notified Party C that Metacrine would no longer be pursuing a transaction with Party C.
On May 11, 2022, Dr. Klassen called Mr. Steel to inform him of certain recent developments with the other merger proposals that Metacrine had received, and to discuss Equillium’s interest in submitting an offer that improved upon its offer from March 2, 2022.
On May 16, 2022, Equillium sent Metacrine a letter of intent including a revised merger proposal to merge with Metacrine and a 30-day exclusivity agreement. Under the revised proposal for an all-stock transaction, Equillium would issue a number of shares of its common stock equal to $37.5 million divided by a per share price based on Equillium common stock’s trailing 10-day VWAP calculated 10 trading days prior to the closing of the merger to the Metacrine stockholders. Equillium’s proposal also included CVRs to Metacrine stockholders in the event Metacrine’s FXR program is successfully licensed or a partnership deal is reached with a third party.
On May 17, 2022, Mr. Steel, Jason Keyes, CFO of Equillium, and Matt Ritter, Ph.D., Senior Vice President of Corporate Development of Equillium, met with members of Metacrine’s management and MTS to discuss the terms of Equillium’s revised merger proposal.
On May 18, 2022, the Metacrine Board met by video conference with Metacrine management present and reviewed the three remaining potential merger parties and their respective offers. Metacrine determined that the clinical and regulatory risk of the Equillium product candidates was lower than of the Party B product candidates and that relative valuation of the Equillium proposal was superior to the relative valuation of the proposal from Party B. Management recommended moving forward with the Equillium merger proposal contingent on extending the time period to achieve and step-down percentage for CVRs related to downstream payments and the Metacrine Board agreed.
On May 19, 2022, with the prior approval of the Metacrine and Equillium boards, Metacrine and Equillium entered into the letter of intent received on May 12, 2022 regarding a merger transaction between Metacrine and Equillium. Following the execution, Metacrine reengaged Wilson Sonsini as counsel for the transaction between Metacrine and Equillium.
On May 21, 2022, MTS on behalf of Metacrine informed Party B that Metacrine was entering into an exclusivity arrangement with another counterparty.

TABLE OF CONTENTS

On July 11, 2022, Wilson Sonsini sent Cooley a draft of the CVR agreement. The parties negotiated the CVR agreement between July 11, 2022 and August 22, 2022.
On July 19, 2022 the exclusivity period between Equillium and Metacrine expired. As a result, Metacrine resumed communication with Party B and explored a number of potential strategic alternatives and discussions with third parties, including Party D. Metacrine also continued discussions with Equillium following the expiration of the exclusivity period.
On July 20, 2022, Party D and Richard Heyman, Chairman of the Metacrine Board, discussed Party D’s potential interest in a potential merger between the two entities.
Later that day the Metacrine Board met with Metacrine management and Wilson Sonsini present to discuss the Merger Agreement and the conversations with Party D.
Also on July 21, 2022, Metacrine and Party D executed a mutual CDA.
On July 22, 2022, Metacrine management and Party D management held an introductory telephonic conversation to discuss a potential merger between the two entities.
Later that day Metacrine received an initial non-binding indication of interest from Party D proposing a merger of the two entities. Party D’s proposal was for an all-stock transaction that valued Metacrine at $42.5 million, Party D at $241 million, resulting in a post-closing ownership split of 15% for Metacrine and 85% for Party D.
On July 27, 2022, the Equillium Board met via video call with Equillium management for an update on the proposed Merger, including the open business points around the CVR and a floor price on the price per share of Equillium common stock. The Equillium Board authorized Equillium’s management to continue to negotiate and pursue the potential Merger.
On July 29, 2022, Metacrine management and Party D management had a telephonic conversation to discuss a potential merger between the two entities.
On August 8, 2022, Dr. Klassen notified Party D that Metacrine would not be further pursuing a transaction with Party D given the expected time required to close such transaction and the lack of synergy with Metacrine’s portfolio.
On August 16, 2022, the Metacrine Board met by video call with Metacrine management and representatives from Wilson Sonsini present to discuss the terms of the Merger Agreement that had been negotiated with Equillium and its counsel, as well as to review the key open items that remained in the negotiations. The proposals and counter-proposals made by Equillium and Metacrine were reviewed, and the Metacrine Board provided guidance to Metacrine management on how to resolve those open points.
On August 18, 2022, Metacrine management and Wilson Sonsini sent an email to Equillium and Cooley on the open items in the Merger Agreement with the parties’ goal of resolving open items that remained in the negotiations.

On August 25, 2022, the Metacrine Board met by video call with Metacrine management and representatives from Wilson Sonsini present to discuss the terms of the Merger Agreement that had been negotiated with Equillium and its counsel, as well as to review the key open items that remained in the negotiations, including Equillium’s proposal to remove the CVR and the floor and ceiling placed on Equillium’s stock price for purposes of determining the merger consideration. The proposals and counter-proposals made by Equillium and Metacrine were reviewed, and the Metacrine Board provided guidance to Metacrine management on how to resolve those open points. The Metacrine Board determined that given the updates with the Potential Licensing Partner, the CVR would have nominal value, given the low probability of executing on a strategic opportunity that would monetize the MET642 program. The Metacrine Board determined that it was in the best interest of the Metacrine stockholders to proceed without the CVR as a part of the transaction with Equillium but insisted on maintaining a ceiling price on Equillium stock price for purposes of determining the merger consideration.

TABLE OF CONTENTS

On August 30, 2022, Dr. Klassen and Mr. Steel had a telephonic conversation and discussed updates to the economics of the transaction including the acceptance of the elimination of the CVR.
Between August 30, 2022 and September 2, 2022, Metacrine and its representatives on one hand, and Equillium and its representatives on the other hand, continued to negotiate the open points on the Merger Agreement and related documents.
On September 2, 2022, the Metacrine Board met by video call with Metacrine management, representatives from Wilson Sonsini and representatives from MTS, an affiliate of MTS Partners, present to review the terms of the revised Merger Agreement. Representatives of Wilson Sonsini reviewed with the Metacrine Board its fiduciary duties in considering a merger of Metacrine with a third party. A representative of MTS then reviewed with the Metacrine Board its financial analysis of the 0.243x exchange ratio, the Projected Exchange Ratio, calculated using Equillium’s 10-Day VWAP of $2.79 as of September 1, 2022 and the implied offer per share value of $0.68 in conjunction with the collar on Equillium’s 10-Day VWAP of $2.70 to $4.50 for purposes of calculating the Projected Exchange Ratio range to be received by the holders of Shares pursuant to the Merger, and MTS then rendered to the Metacrine Board its oral opinion (which was subsequently confirmed by delivery of the September MTS Opinion) that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in such written opinion, the Exchange Ratio to be received by the Metacrine stockholders pursuant to the Merger was fair, from a financial point of view, to such Metacrine stockholders. The full text of the September MTS Opinion sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by MTS in connection with its opinion; for more information see “The MergerOpinions of Metacrine’s Financial Advisor—September MTS Opinion” beginning on page 103 of this joint proxy statement/prospectus.
On September 3, 2022 and September 4, 2022, Equillium and Metacrine and their management teams and advisors finalized the Merger Agreement. Those negotiations resulted in revisions to the definition of net cash, including the removal of positive adjustments previously included and related to the strategic opportunity with the Potential Licensing Partner.
On September 5, 2022, the Equillium Board met via video call with Equillium management, representatives from Cooley and representatives from VPA, present to review the terms of the Merger Agreement. Representatives of Cooley reviewed with the Equillium Board its fiduciary duties in considering an acquisition of a third party.

The full text of the written opinion of VPA sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by VPA in connection with its opinion; for more information see “The Merger—Opinion of Equillium’s Financial Advisor.” Following the issuance of VPA’s oral opinion, the Equillium Board determined, for the reasons detailed in “The Merger—Recommendation of the Equillium Board; Equillium’s Reasons for the Merger” beginning on page 87 of this joint proxy statement/prospectus, that the transactions contemplated by the Merger Agreement were advisable, fair to and in the best interests of Equillium and its stockholders, approved the Merger Agreement and recommended that the stockholders of Equillium vote in favor of adopting the Merger Agreement.
On September 6, 2022, the Metacrine Board then determined by unanimous written consent, for the reasons detailed in “The Merger—Recommendation of the Metacrine Board; Metacrine’s Reasons for the Merger” beginning on page 88 of this joint proxy statement/prospectus, that the transactions contemplated by the Merger Agreement were advisable, fair to and in the best interests of Metacrine and its stockholders, approved the Merger Agreement and recommended that the Metacrine stockholders vote in favor of adopting the Merger Agreement, or the Approval.
Later that day, Metacrine and Equillium executed the Merger Agreement, or the signing, and the parties issued a joint press release announcing the execution of the Merger Agreement.
On September 30, 2022, Metacrine entered into a license agreement, or the HSD License Agreement, with FL 2022-001, Inc., or Licensee, a portfolio company of Foresite Labs, pursuant to which Metacrine granted

Metacrine will also be entitled to receive royalties on tiers of annual net sales of Licensed Products at rates in the low single digits, on a Licensed Product-by-Licensed Product and country-by-country basis, until the expiration of the last patent covering such Licensed Product in such country.
On October 4, 2022, Metacrine management, Equillium management, representatives of MTS Partners, Wilson Sonsini and Cooley met by video conference to discuss this joint proxy statement/prospectus. Among other matters, the parties discussed Equillium’s current strategic initiatives regarding certain of its product candidates, and the adjustments underlying the Metacrine-Prepared Projections created ahead of Signing and the September MTS Opinion, or the September Opinion Projections.
On October 11, 2022, Metacrine management, Wilson Sonsini, representatives of MTS Partners and MTS’ counsel, Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., or Mintz, met by video conference to further discuss Equillium’s current strategic initiatives regarding certain of its product candidates, and the adjustments underlying the September Opinion Projections. In light of these conversations, Metacrine management in consultation with its advisors determined that additional financial projections, along with a revised fairness opinion from MTS, should be prepared and presented to the Metacrine Board.
On October 19, 2022, the Metacrine Board met by video conference with Metacrine management and representatives of Wilson Sonsini and MTS present. In light of the adjustments discussed above, Metacrine management presented to the Metacrine Board revised Metacrine-Prepared Projections, or the October Opinion Projections, and together with the September Opinion Projections, the Metacrine-Prepared Projections; for more information see “Equillium Financial Projections Used By Metacrine’s Financial Advisor” beginning on page 92 of this joint proxy statement/prospectus. During the meeting, representatives of MTS reviewed with the Metacrine Board its financial analysis of the Projected Exchange Ratio of 0.282x, calculated using the collar floor of Equillium’s 10-Day VWAP of $2.70 as of October 18, 2022, and the implied offer per share of $0.58, and MTS then rendered to the Metacrine Board its oral opinion (which was subsequently confirmed by delivery of the October MTS Opinion) that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in such written opinion, the Exchange Ratio to be received by the Metacrine stockholders pursuant to the Merger was fair, from a financial point of view, to such Metacrine stockholders. The full text of the October MTS Opinion sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by MTS in connection with its opinion; for more information see “The MergerOpinions of Metacrine’s Financial Advisor—October MTS Opinion” beginning on page 110 of this joint proxy statement/prospectus. Following the issuance of MTS’ revised oral opinion, the Metacrine Board determined, for the reasons detailed in “The Merger—Recommendation of the Metacrine Board; Metacrine’s Reasons for the Merger” beginning on page 88 of this joint proxy statement/prospectus, to reaffirm the Approval.

Equillium’s Reasons for the Merger; Recommendation of the Stock Issuance by the Equillium Board
In evaluating the Merger Agreement and the proposal to issue shares of Equillium common stock in connection with the combination, the Equillium Board consulted with Equillium’s management and legal and financial advisors. In connection therewith, the Equillium Board considered a number of factors, including the following factors (which factors are not necessarily presented in order of relative importance) that the Equillium Board viewed as generally supporting its decision to approve and enter into the proposed Merger Agreement and recommend that Equillium stockholders vote “FOR” approval of the Equillium stock issuance proposal:
Strategic Factors. The Equillium Board evaluated the following key strategic factors supporting its approval of and entry into the proposed Merger Agreement:
that the proposed Merger strengthens Equillium’s cash position, better positioning Equillium to pursue continued development of its programs and will fund Equillium through important clinical milestones;
the limited financing alternatives given market conditions;
that the terms of the proposed Merger were considered to be favorable to financing alternatives that may have been available to Equillium;
that the addition of Metacrine’s pipeline programs enables possible advancement of these programs through strategic partnership or divestiture, which Equillium believes may further benefit Equillium stockholders; and
through the addition of Dr. Klassen to the Equillium Board, Equillium adds further clinical development expertise and maintains continuity with respect to the acquired Metacrine programs.
Other Factors Considered by the Equillium Board. In addition to considering the strategic factors described above, the Equillium Board considered the following additional factors, all of which it viewed as supporting its decision to approve the proposed combination:
its knowledge of Equillium’s business, operations, financial condition, earnings and prospects on a standalone basis and of Metacrine’s business, operations, financial condition, earnings and prospects, taking into account the results of Equillium’s due diligence review of Metacrine;
the fixed percentage premium paid on Metacrine’s Net Cash provides greater certainty as to the value being paid for the cash to be delivered at the Closing;
the opinion of VPA, dated September 6, 2022, to the Equillium Board, which opinion is attached hereto as Annex B, to the effect that, as of that date and based on and subject to various assumptions and limitations described in their opinion, the Merger transaction was fair, from a financial point of view, to Equillium stockholders, as more fully described below under the caption “The Merger—Opinion of Equillium’s Financial Advisor”;
the terms and conditions of the Merger Agreement; and
the reasonableness of the potential termination fee (i) of up to $1,250,000 which could become payable by Metacrine if the Merger Agreement is terminated in certain circumstances and (ii) of up to $1,750,000, which could become payable by Equillium if the Merger Agreement is terminated in certain circumstances.
The Equillium Board weighed the advantages and opportunities listed above against a number of other factors identified in its deliberations as weighing negatively against the proposed combination, including:
the risk that the transaction and integration costs may be greater than anticipated;
the cost of the transaction, including dilution to Equillium stockholders, as compared to other potential means of raising capital;
the cost, including the time spent by Equillium’s management, associated with a decision to pursue a strategic transactions to divest or otherwise monetize Metacrine’s legacy assets as a financing alternative;
87

TABLE OF CONTENTS

the impact that the announced transaction may have on Equillium’s stock price and on Equillium’s ability to raise additional capital or engage in certain business development discussions during the pre-closing period;
the substantial cost of integrating the two companies;
the risk of not achieving all of the anticipated synergies and the risk that strategic benefits and other anticipated benefits might not be realized or may take longer than expected to achieve;
the likelihood of disruptive stockholder litigation following announcement of the Merger; and
various other risks associated with Metacrine and the Merger, including the risks described in the section entitled “Risk Factors,” and the matters described under “Cautionary Statement Regarding Forward-Looking Statements.”
This discussion is not meant to be exhaustive. Rather, it summarizes the material reasons and factors evaluated by the Equillium Board in its consideration of the Merger. After considering these and other factors and through discussions with Equillium’s management and outside legal and financial advisors, the Equillium Board concluded that the potential benefits of entering into the Merger Agreement outweighed the uncertainties and risks. In view of the factors considered in connection with its evaluation of the proposed Merger and the complexity of these matters, the Equillium Board did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the proposed Merger and the Merger Agreement and to make its recommendation to Equillium stockholders. In addition, individual members of the Equillium Board may have given differing weights to different factors and applied his or her own personal business judgment to the process. The Equillium Board determined that the proposed Merger, the Merger Agreement and the transactions contemplated by the Merger Agreement, including the issuance of shares of Equillium common stock to Metacrine stockholders in connection with the combination, were in the best interests of Equillium and its stockholders and approved the Merger Agreement and the transactions contemplated by the Merger Agreement.
The Equillium Board recommends that Equillium stockholders vote “FOR” the Equillium stock issuance proposal and “FOR” the Equillium adjournment proposal.
Metacrine's Reasons for the Merger; Recommendation of the Merger by the Metacrine Board
On September 5, 2022, among other things, the Metacrine Board:
determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are advisable and in the best interests of Metacrine and its stockholders;
approved the Merger Agreement and the Merger, the execution of the Merger Agreement and the consummation of the transactions contemplated thereby; and
declared advisable and recommended that Metacrine's stockholders adopt the Merger Agreement.
On October 19, 2022, among other things, the Metacrine Board reaffirmed the Approval.
In evaluating the Merger Agreement and the Merger, the Metacrine Board consulted with Metacrine management, as well as its advisors. In recommending that Metacrine stockholders vote “FOR” the adoption of the Merger Agreement, the Metacrine Board considered and analyzed a number of factors, including the below (which factors are not necessarily presented in order of relative importance). Based on these consultations, considerations and analyses, and the factors discussed below, the Metacrine Board concluded that entering into the Merger Agreement with Equillium was advisable and in the best interests of Metacrine and our stockholders.
The Metacrine Board believed that the following material factors and benefits supported its determinations and recommendation:
The Merger was the result of an extensive strategic review process. The Metacrine Board considered that the Metacrine management team and, at Metacrine’s direction, MTS Partners affirmatively contacted 18 companies (including Equillium) concerning a potential merger, acquisition or strategic

TABLE OF CONTENTS

partnership. The Metacrine Board considered the nature of the engagement by each of these potential acquirers and partners over a multiple month period and that, of these potential acquirers and partners, only Equillium made a proposal for an acquisition of Metacrine that was capable of being accepted and proceeding to closing within a timely manner;
The opinions of MTS that were rendered orally on September 2, 2022 and October 19, 2022, and subsequently confirmed by the September MTS Opinion and October MTS Opinion, respectively, that as of the applicable date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in the September MTS Opinion and the October MTS Opinion, as applicable, the Exchange Ratio to be received by the holders of Metacrine common stock pursuant to the offer and the Merger was fair, from a financial point of view, to such holders, as more fully described in “The Merger—Opinions of Metacrine’s Financial Advisor” below and in Annex C-1 and C-2 to this joint proxy statement/prospectus;
The Metacrine Board’s belief, as a result of arm’s length negotiations with Equillium and taking into account the Metacrine Board’s familiarity with the business, operations, prospects, business strategy, assets, liabilities and general financial condition of Metacrine on a historical and prospective basis, that (i) Metacrine and its representatives negotiated the most favorable Exchange Ratio that Equillium was willing to agree to, (ii) measured against the longer-term execution risks described above, the per share merger consideration reflects a fair and favorable price for the shares of Metacrine common stock and (iii) the terms of the Merger Agreement include the most favorable terms to Metacrine in the aggregate to which Equillium was willing to agree, and which provide a high level of closing certainty;
The Metacrine Board’s belief, based in part on a scientific diligence and analysis process conducted over several weeks by Metacrine’s management and reviewed with the Equillium Board, that with respect to Equillium’s product pipeline and the potential market opportunity for Equillium’s products, that Equillium’s product candidates represent a sizeable potential market opportunity, and may thereby create value for the stockholders of the combined organization and an opportunity for Metacrine’s stockholders to participate in the potential growth of the combined organization;
The cash constraints of Metacrine in light of the current, historical and projected financial condition, results of operations and business of Metacrine, and the general lack of interest seen from the significant number of potential licensing partners that certain members of the Metacrine Board and Metacrine management contacted in connection with advancing and providing capital to Metacrine’s MET642 program, and the likelihood that Metacrine’s prospects as a stand-alone company were unlikely to change for the benefit of Metacrine’s stockholders in the foreseeable future;
The Metacrine Board’s understanding of the business operations, financial conditions and constraints, earnings and prospects of Metacrine, including the prospects of Metacrine on a stand-alone basis;
The Metacrine Board’s belief, after a thorough review of strategic alternatives and discussions with Metacrine’s management, financial advisors and legal counsel, that the Merger is more favorable to Metacrine’s stockholders than the potential value that might have resulted from other strategic options available to Metacrine, including a liquidation of Metacrine and the distribution of any available cash;
The risks and delays associated with, and uncertain value and costs to Metacrine’s stockholders of, liquidating Metacrine, including, without limitation, the uncertainties of continuing cash burn while contingent liabilities are resolved and uncertainty of timing of release of cash until contingent liabilities are resolved;
The fact that the estimated return to each stockholder in a liquidation of Metacrine would result in a payment of approximately $0.58 per share of Metacrine Common Stock and based on the value of the Exchange Ratio as of each of September 2, 2022 and October 19, 2022 (the dates of the respective oral fairness opinions of MTS were delivered) the implied Pro Forma Metacrine Per Share Value Range were approximately $0.76-$1.33 and $1.80-$3.60 as of September 2, 2022 and October 19, 2022, respectively. See the sections entitled “The Merger—Opinions of Metacrine’s Financial Advisor—September MTS Opinion—Pro Forma Combination Analysis” and “The Merger—Opinions of Metacrine’s Financial Advisor—October MTS Opinion—Intrinsic Value of Merger Consideration”; and

TABLE OF CONTENTS

The fact that Metacrine’s other potential acquirers and partners are private companies with valuations that are not validated by the public markets.
The Metacrine Board also reviewed the terms and conditions of the Merger Agreement and related transactions, as well as the safeguards and protective provisions included therein intended to mitigate risks, including:
The initial estimated Exchange Ratio used to establish the number of shares of Equillium common stock to be issued to Metacrine’s stockholders in the Merger was determined based on the relative valuations of Equillium and Metacrine, and thus the relative percentage ownership of Equillium’s stockholders and Metacrine’s stockholders immediately following the completion of the Merger is subject to change based on the amount of Metacrine’s Net Cash and the Equillium stock price;
The limited number and nature of the conditions to Equillium’s obligation to consummate the Merger and the limited risk of non-satisfaction of such conditions as well as the likelihood that the Merger will be consummated on a timely basis;
The respective rights of, and limitations on, Equillium and Metacrine under the Merger Agreement to consider certain unsolicited acquisition proposals under certain circumstances should Equillium or Metacrine receive a superior offer;
The reasonableness of the potential termination fee (i) of up to $1,250,000 which could become payable by Metacrine if the Merger Agreement is terminated in certain circumstances and (ii) of up to $1,750,000, which could become payable by Equillium if the Merger Agreement is terminated in certain circumstances; and
The belief that the terms of the Merger Agreement, including the parties’ representations, warranties and covenants, and the conditions to their respective obligations, are reasonable under the circumstances.
The Metacrine Board also considered a number of uncertainties and risks and other potentially negative factors, including the following:
The risks and delays associated with, and uncertain value and costs to Metacrine’s stockholders of, liquidating Metacrine, including, without limitation, the uncertainties of continuing cash burn while contingent liabilities are resolved and uncertainty of timing of release of cash until contingent liabilities are resolved;
The Merger might not be completed in a timely manner, or at all, and the potential adverse effect of the public announcement of the Merger or delay or failure to complete the Merger on the business, operations and financial results of Metacrine, reputation of Metacrine and the ability of Metacrine to obtain financing in the future;
The Merger Agreement includes a closing condition that requires Metacrine’s Net Cash be at least $23 million at the Effective Time. In the event that Metacrine’s Net Cash balance falls below this threshold, Equillium would not be obligated to, but could in its sole discretion elect to, consummate the Merger, which would result in Metacrine’s stockholders holding a smaller than expected percentage of the post-closing combined company;
The likely detrimental effect on Metacrine’s cash position, stock price and ability to initiate another process and to successfully complete an alternative transaction should the Merger not be completed;
(i) The $1,250,000 termination fee payable by Metacrine to Equillium under certain circumstances, including termination by Metacrine to accept and enter into a definitive agreement with respect to a superior proposal and (ii) the $1,750,000 termination fee payable by Equillium to Metacrine under certain circumstances, including termination by Equillium to accept and enter into a definitive agreement with respect to a superior proposal and (iii) the potential effect of the fees describe in clauses (i) and (ii) in deterring other potential acquirers from proposing an alternative transaction that may be more advantageous to Metacrine’s stockholders;
The possible volatility, at least in the short term, of the trading price of Equillium and Metacrine common stock resulting from the announcement of the Merger;
90

TABLE OF CONTENTS

The likelihood of disruptive stockholder litigation following announcement of the Merger;
The early-stage clinical data of Equillium’s product candidates, which, in the future, may not be successfully developed into products that are marketed and sold;
The strategic direction of the combined company following the completion of the Merger, which will be determined by a board of directors initially comprised of a majority of the directors designated by Equillium;
The expenses to be incurred in connection with the Merger and related administrative challenges associated with combining the companies, including the costs associated with any related litigation; and
Various other risks associated with Metacrine and the Merger, including the risks described in the section entitled “Risk Factors” beginning on page 30 of this joint proxy statement/prospectus.
This discussion is not meant to be exhaustive. Rather, it summarizes the material reasons and factors evaluated by the Metacrine Board in its consideration of the Merger. After considering these and other factors, the Metacrine Board concluded that the potential benefits of entering into the Merger Agreement outweighed the uncertainties and risks. In light of the variety of factors considered by the Metacrine Board and the complexity of these factors, the Metacrine Board did not find it practicable to, and did not, quantify or otherwise assign relative weights to the foregoing factors in reaching its determination and recommendations. Moreover, each member of the Metacrine Board applied his or her own personal business judgment to the process and may have assigned different relative weights to the different factors. The Metacrine Board adopted and approved the Merger Agreement and the Merger, and recommended that Metacrine stockholders adopt the Merger Agreement, based upon the totality of the information presented to, and considered by, the Metacrine Board.
In addition, the Metacrine Board considered the interests that certain of its directors and executive officers may have with respect to the Merger that are different from or in addition to their interests as stockholders of Metacrine, generally and specifically as more fully described under “The Merger—Financial Interests of Metacrine Directors and Executive Officers in the Merger”. The Metacrine Board concluded that the risks, uncertainties, restrictions and potentially negative factors associated with the Merger were outweighed by the potential benefits of the Merger.
In view of the factors considered in connection with its evaluation of the proposed merger and the complexity of these matters, the Metacrine Board did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the proposed merger and the Merger Agreement and to make its recommendation to Metacrine stockholders. In addition, individual members of the Metacrine Board may have given differing weights to different factors. In reaching its determination to approve the proposed merger and the Merger Agreement, the Metacrine Board conducted an overall review of the factors described above, including thorough discussions with Metacrine's management and outside legal and financial advisors.
The Metacrine Board recommends that Metacrine’s stockholders vote “FOR” adoption of the Merger Agreement.

EQUILLIUM FINANCIAL PROJECTIONS USED BY METACRINE’S FINANCIAL ADVISOR
Metacrine’s Unaudited Financial Projections Regarding Equillium
As a matter of course, neither Equillium nor Metacrine publicly discloses long-term projections of future financial results due to the inherent unpredictability and subjectivity of underlying assumptions and estimates. However, in connection with the Metacrine Board’s evaluation of the Merger, preliminary internal financial projections for Equillium were prepared by the management of Equillium and provided to the management of Metacrine, and then adjusted by the management of Metacrine, or the Metacrine-Prepared Projections, solely for use by MTS in connection with the rendering of its fairness opinion and performing its related financial analyses, as described below under “The Merger—Opinions of Metacrine’s Financial Advisor”.
The inclusion of the Metacrine-Prepared Projections below should not be deemed an admission or representation by Metacrine, Equillium, MTS Partners, MTS or any of their respective officers, directors, affiliates, advisors, or other representatives with respect to such projections. The Metacrine-Prepared Projections are not included to influence your views on the Merger described in this joint proxy statement/prospectus but solely to provide stockholders access to certain non-public information that was provided to the Metacrine Board in connection with its evaluation of the Merger and to Metacrine's financial advisor, MTS Partners, to assist with its financial analyses as described in the section entitled “Opinions of Metacrine's Financial Advisor.” The information from the Metacrine-Prepared Projections included below should be evaluated, if at all, in conjunction with the historical financial statements and other information regarding Equillium and Metacrine in this joint proxy statement/prospectus or incorporated herein by reference.
The Metacrine-Prepared Projections were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with published guidelines of the SEC, the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, or GAAP. Neither the independent registered public accounting firm of Metacrine nor Equillium nor any other independent accountant has audited, reviewed, compiled, examined or performed any procedures with respect to the Metacrine-Prepared Projections for the purpose of its inclusion herein, and accordingly, neither the independent registered public accounting firm of Metacrine nor Equillium, nor any other independent accountant expresses an opinion or provides any form of assurance with respect thereto for the purpose of this joint proxy statement/prospectus.
The financial projections prepared by Equillium and supplied to Metacrine were prepared for internal use as part of Equillium’s ongoing strategic planning processes and are subjective in many respects. As a result, the Metacrine-Prepared Projections, are susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. Although Metacrine and Equillium believe their respective assumptions to be reasonable, all financial projections are inherently uncertain, and Metacrine and Equillium expect that differences will exist between actual and projected results. Although presented with numerical specificity, the Metacrine-Prepared Projections reflect numerous variables, estimates, and assumptions made by Metacrine's and Equillium’s respective management at the time they were prepared by Equillium and adjusted by Metacrine, and also reflect general business, economic, market, and financial conditions and other matters, all of which are difficult to predict and many of which are beyond Metacrine's and Equillium’s control. In addition, the Metacrine-Prepared Projections cover multiple years, and this information by its nature becomes subject to greater uncertainty with each successive year. Accordingly, there can be no assurance that the estimates and assumptions made in preparing the Metacrine-Prepared Projections will prove accurate or that any of the Metacrine-Prepared Projections will be realized.
The Metacrine-Prepared Projections include unlevered free cash flow, total adjusted revenue, earnings before interest and taxes, or EBIT and earnings before taxes less other income, or EBT, which are “non-GAAP financial measures” which are financial performance measures that are not calculated in accordance with GAAP. Non-GAAP financial measures should not be viewed as a substitute for GAAP financial measures and may be different from non-GAAP financial measures used by other companies. Furthermore, there are limitations inherent in non-GAAP financial measures because they exclude charges and credits that are required to be included in a GAAP presentation. Accordingly, non-GAAP financial measures should be considered together with, and not as an alternative to, financial measures prepared in accordance with GAAP. The SEC rules, which otherwise would require a reconciliation of a non-GAAP financial measure to a GAAP financial measure, do not apply to non-GAAP financial measures provided to a board of directors or financial advisors in connection with the proposed Merger if the disclosure is included in a document such as this joint proxy statement/prospectus to

TABLE OF CONTENTS

comply with requirements under state laws, including case law. The Metacrine-Prepared Projections were provided to MTS Partners and MTS in order for it to render the MTS Opinions and to the Metacrine Board in connection with its consideration of the Merger and other strategic alternatives, and we believe we have an obligation to disclose such projections under Delaware law, including applicable case law, in order to provide a fair summary of certain of the financial analyses and substantive work of MTS Partners and MTS and because the Metacrine-Prepared Projections were relied upon by the Metacrine Board in connection with its consideration of the Merger and other strategic alternatives. In addition, reconciliations of non-GAAP financial measures to a GAAP financial measure were not provided to or relied upon by MTS Partners and MTS in connection with rendering the MTS Opinions with respect to the Merger, as further described in the section titled “The Merger—Opinions of the Metacrine’s Financial Advisor.” Accordingly, Metacrine has not provided a reconciliation of the financial measures included in the Metacrine-Prepared Projections to the relevant GAAP financial measures.
The Metacrine-Prepared Projections included certain assumptions relating to, among others things, Metacrine's and Equillium’s respective expectations, which may not prove to be accurate, relating to the business, earnings, cash flow, assets, liabilities and prospects of Equillium.
The Metacrine-Prepared Projections are subject to many risks and uncertainties and you are urged to review the section entitled “Risk Factors” beginning on page 30 of this joint proxy statement/prospectus for a description of risk factors relating to the Merger. You should also read the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 41 of this joint proxy statement/prospectus for additional information regarding the risks inherent in forward-looking information such as the Metacrine-Prepared Projections.
The inclusion of the Metacrine-Prepared Projections herein should not be regarded as an indication that Metacrine, Equillium, MTS or any of their respective affiliates or representatives considered or consider the Metacrine-Prepared Projections to be necessarily indicative of actual future events, and the Metacrine-Prepared Projections should not be relied upon as such. The Metacrine-Prepared Projections do not take into account any circumstances or events occurring after the dates they were prepared. Metacrine and the post-closing combined company do not intend to, and disclaims any obligation to, update, correct, or otherwise revise the Metacrine-Prepared Projections to reflect circumstances existing or arising after the date the Metacrine-Prepared Projections were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions or other information underlying the Metacrine-Prepared Projections are shown to be in error. Furthermore, the Metacrine-Prepared Projections do not take into account the effect of any failure of the Merger to be consummated and should not be viewed as accurate or continuing in that context.
In light of the foregoing factors and the uncertainties inherent in financial projections, stockholders are cautioned not to place undue reliance, if any, on the Metacrine-Prepared Projections.

VPA relied upon and assumed the accuracy, completeness and reasonableness of all industry, business, financial, legal, regulatory, tax, accounting, actuarial and other information furnished by or discussed with Equillium or obtained from reputable public sources, data suppliers and other third parties.

Specifically, with respect to (i) any estimates furnished by or discussed with Equillium, VPA was advised by Equillium’s management, and VPA assumed, that such estimates utilized in its analyses had been reasonably prepared on bases reflecting the best then-currently available estimates and judgments of Equillium’s management as to the expected future performance of Equillium, and (ii) any estimates obtained by VPA from public sources, data suppliers and other third parties, VPA assumed that such estimate was reasonable and reliable.

Summary of Valuation and Financial Analyses
Overview of Valuation and Financial Analyses
This “Summary of Valuation and Financial Analyses” presents a summary of the principal valuation and financial analyses performed by VPA and presented to the Equillium Board in connection with VPA’s rendering of its opinion. Such presentation to the Equillium Board was supplemented by VPA’s oral discussion, the nature and substance of which may not be fully described herein.
Some of the valuation and financial analyses summarized below include summary data and information presented in tabular format. In order to understand fully such valuation and financial analyses, the summary data and tables must be read together with the full text of the summary. Considering the summary data and tables alone could create a misleading or incomplete view of VPA’s valuation and financial analyses.

TABLE OF CONTENTS

The preparation of a fairness opinion is a complex process and involves various judgments and determinations as to the most appropriate and relevant valuation and financial analyses and the application of those methods to the particular circumstances involved. A fairness opinion therefore is not readily susceptible to partial analysis or summary description, and taking portions of the valuation and financial analyses set forth below, without considering such analyses as a whole, would in VPA’s view create an incomplete and misleading picture of the processes underlying the valuation and financial analyses considered in rendering VPA’s opinion.
In arriving at its opinion, VPA:
based its valuation and financial analyses on assumptions that it deemed reasonable, including assumptions concerning general business and economic conditions, capital markets considerations and industry-specific and company-specific factors, all of which are beyond the control of Equillium, Metacrine, and VPA;
did not form a view or opinion as to whether any individual analysis or factor, whether positive or negative, considered in isolation, supported or failed to support its opinion;
considered the results of all of its valuation and financial analyses and did not attribute any particular weight to any one analysis or factor; and
ultimately arrived at its opinion based on the results of all of its valuation and financial analyses assessed as a whole and believes that the totality of the factors considered and the various valuation and financial analyses performed by VPA in connection with its opinion operated collectively to support its determination as to the fairness of the Merger, from a financial point of view, to Equillium’s common stockholders.
With respect to the valuation and financial analyses performed by VPA in connection with rendering its opinion:
Such valuation and financial analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than suggested by these analyses.
None of the selected precedent merger and acquisition transactions used in the precedent merger and acquisitions transactions analysis described below is identical or directly comparable to the Merger; however, such companies and transactions were selected by VPA based on its acumen and experience.
In any event, the precedent merger and acquisition transactions analysis are not mathematical; rather, such analyses involve complex considerations and judgments concerning the differences in business, financial, operating and capital markets-related characteristics and other factors regarding the peer group companies and precedent merger and acquisition transactions to which Equillium and the Merger were compared.
Such valuation and financial analyses do not purport to be appraisals or to reflect the prices at which any securities may trade at the present time or at any time in the future.
Recap of Merger Valuation
Assumed Value: For purposes of its financial analyses, with Equillium’s consent, VPA assumed that the Merger Consideration had a value equal to Metacrine’s net cash multiplied by 1.25.
In evaluating the Merger Consideration, VPA performed analyses on Metacrine and Equillium.
Metacrine Valuation
Given that the assets and liabilities involved in the Merger are cash and debt, the asset approach was determined to be relevant. Per the Merger Agreement, the minimum Net Cash will be $23.0 million. VPA noted that Metacrine had a Phase 2-ready program (MET 642), but based on the lack of progress with the asset and the September 2, 2022 market capitalization of Metacrine of $19.5 million being lower than the most recent publicly filed net cash figure of $40.9 million as of June 30, 2022 as outlined in its 10-Q filing, no value was ascribed to the MET 642 asset.

TABLE OF CONTENTS

PIPE Study
According to the Merger Agreement, the Merger Consideration is equal to Metacrine’s net cash multiplied by 1.25. Given the circumstances of the Transaction, VPA considered this 25.0 percent premium to net cash as the cost to raise an equivalent amount of capital. Typical costs to raise capital include, but are not limited to, a discount to a company’s public stock price as well as underwriting/brokerage fees.
In order to assess the 25.0 percent premium, VPA performed an analysis of discounts and fees reported in transactions involving Private Investments in Public Equity, or PIPEs. A PIPE refers to a private placement of securities of an already-public company that is made to selected accredited investors (usually to selected qualified institutional buyers) wherein investors enter into a purchase agreement committing them to purchase such securities and, usually, requiring the issuer to file a resale registration statement covering the resale from time to time of the securities the investors purchased in the private placement.
VPA screened for biotechnology PIPE transactions looking back five years and found 136 transactions between $0.5 million and $100.0 million in size, including 14 in 2022 and 27 in 2021. VPA also found 123 transactions sized $0.5 million to $50.0 million, including 12 in 2022 and 24 in 2021.
VPA observed the fees and discounts associated with the transactions and the premiums implied by the changes in stock prices prior to the announcement date (over a variety of time periods) and noted that the 25.0 percent premium typically fell within the range of the first and third quartile indications, was near the median of the aggregate statistics and was in line with the 5-day 2022 median and compared favorably to the 2022 10- and 15-day median indications. data.

Valuation of Equillium
Because Equillium is a company with registered securities that trade on a public exchange, VPA analyzed its equity value based on its publicly-traded stock price as of September 2, 2022, as well as its VWAP for the 5-day, 10-day, 15-day, 20-day, and 3-month periods prior to September 2, 2022. Given Equillium’s trading volume and change in price, VPA assumed the publicly-traded stock price was a reliable indication of value. Please find the results in the following table:

TABLE OF CONTENTS

In selecting the publicly traded stock price as a reasonable indication of value, key considerations in VPA’s analysis included, but were not limited to: (i) general market conditions, (ii) biotech sector sentiment, (iii) rising interest rates and the cost of capital for long duration assets, (iv) a challenging fundraising environment, (v) the trading liquidity of Equillium stock, (vi) Equillium’s cash requirements and (vii) equity analyst coverage detailing Equillium’s operations.
Other Considerations
Equillium did not provide specific instructions to, or place any limitations on, VPA with respect to the procedures to be followed or factors to be considered in performing its valuation and financial analyses or providing its opinion. The type and amount of consideration payable in the Merger were determined through negotiations between Equillium and Metacrine and were approved by the Equillium Board. The decision to enter into the Merger Agreement was solely that of the Equillium Board. VPA’s opinion was just one of the many factors taken into consideration by the Equillium Board. Consequently, VPA’s valuation and financial analyses should not be viewed as determinative of the decision of the Equillium Board with respect to the fairness of the Merger, from a financial point of view, to Equillium’s common stockholders.
Pursuant to the terms of the engagement letter of VPA, Equillium has agreed to pay VPA an aggregate fee of $120,000 with $48,000 payable upon the execution of the engagement letter and $72,000 payable at the time, following request by the Equillium Board, VPA informs the Equillium Board that VPA is prepared to deliver its opinion. In addition, Equillium has agreed to reimburse VPA for certain expenses (including, up to $10,000 of legal expenses) and to indemnify it against certain liabilities arising out of its engagement. No portion of VPA’s fees or expense reimbursement is subject to the successful completion of the transaction.
Aside from its current engagement by Equillium in connection with the Transaction, VPA has not been previously engaged during the past two years by Equillium or Metacrine.

TABLE OF CONTENTS

In arriving at the September MTS Opinion, MTS assumed and relied upon, without assuming liability or responsibility for independent verification, the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information that was publicly available or was provided to, discussed with or reviewed by MTS and upon the assurances of the management of Metacrine that they are not aware of any material relevant developments or matters related to Metacrine or Equillium, respectively, or that may affect the Merger that have been omitted or that remain undisclosed to MTS. The September MTS Opinion does not address any legal, regulatory, tax, accounting, or financial reporting matters, as to which MTS understands that Metacrine has obtained such advice as it deemed necessary from other advisors, and MTS relied, with Metacrine’s consent, on such assessments made by such other advisors to Metacrine with respect to such matters. MTS did not conduct any independent verification of the September Opinion Projections. Without limiting the generality of the foregoing, with respect to the September Opinion Projections, MTS assumed, with Metacrine’s consent, and based upon discussions with the management of Metacrine, that they have been reasonably prepared (or in the case of the September Opinion Projections, adjusted) by the management of Metacrine in good faith, and that the September Opinion Projections reflected the best currently available estimates and judgments of the management of Metacrine of the future results of operations and financial performance of Equillium. The September Opinion Projections are based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions and, in particular, assumptions regarding increased market volatility and the widespread disruption, extraordinary uncertainty and unusual volatility arising from the effects of the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. Accordingly, actual results could vary significantly from those set forth in the September Opinion Projections. MTS expressed no view as to the September Opinion Projections or the assumptions on which they were based and MTS assumed no responsibility for the accuracy or completeness thereof.
In arriving at the September MTS Opinion, MTS did not make any independent evaluations or appraisals of the assets or liabilities of Metacrine or Equillium or any of their respective subsidiaries, and MTS was not furnished with any such evaluations or appraisals, nor did MTS evaluate the solvency of Metacrine, Equillium or any other entity under any state or federal law relating to bankruptcy, insolvency or similar matters. MTS assumed that there had been no material change in the assets, financial condition, business or prospects of Metacrine or Equillium since the date of the most recent relevant financial information made available to MTS. Without limiting the generality of the foregoing, MTS undertook no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which Metacrine, Equillium or any of their respective affiliates is a party or may be subject, and, at the direction of the Metacrine Board and with the Metacrine Board’s consent, the September MTS Opinion made no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. MTS also assumed that neither Metacrine, Equillium, Acquisition Sub or Merger Sub is a party to any material pending transaction that has not been disclosed to MTS, including, without limitation, any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger.
MTS assumed that the representations and warranties of each party contained in the Merger Agreement and in all other related documents and instruments that are referred to therein would be true and correct as of the date or the dates made or deemed made, that each party thereto will fully and timely perform all of the covenants and agreements required to be performed by it under the Merger Agreement and any other agreement contemplated thereby, and that the transactions contemplated by the Merger Agreement, including, without limitation, the Merger, will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement. MTS assumed that the final form of the Merger Agreement would be identical to the Draft Merger Agreement in all material respects. MTS, with the Metacrine Board’s consent, further assumed that any adjustment to the Merger Consideration pursuant to the terms of the Merger Agreement would not result in any adjustment to the Merger Consideration that was material to MTS’s analysis. MTS also assumed that any governmental, regulatory and other consents and approvals contemplated in connection with the Merger would be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions would be imposed or waivers made that would have an adverse effect on Metacrine, Equillium, Acquisition Sub, Merger Sub or the contemplated benefits of the Merger.
The September MTS Opinion was necessarily based on economic, market, financial and other conditions as they existed, and on the information made available to MTS, as of September 2, 2022. MTS did not consider any potential legislative or regulatory changes currently being considered by the United States Congress, the SEC, or any other governmental or regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. It should be understood that, although
104

TABLE OF CONTENTS

subsequent developments may affect the conclusion reached in the MTS Opinion, MTS has no obligation to update, revise or reaffirm the September MTS Opinion. The September MTS Opinion addressed solely the fairness, from a financial point of view and as of the date thereof, of the Exchange Ratio to the holders of Metacrine common stock (other than the Excluded Shares), and did not address any other terms in the Merger Agreement, or any other agreement contemplated by the Merger Agreement or relating to the Merger or any other aspect or implication of the Merger, including, without limitation, the form or structure of the Merger, or the fairness of the Merger or the Exchange Ratio to any other securityholders or creditors or any other constituency of Metacrine, including holders of Company Options (as defined in the Draft Merger Agreement), Company Warrants (as defined in the Draft Merger Agreement) and Company RSUs (as defined in the Draft Merger Agreement) and participations in the ESPP (as defined in the Draft Merger Agreement). The September MTS Opinion did not address Metacrine’s underlying business decision to proceed with the Merger or the relative merits of the Merger compared to other alternatives available to Metacrine. MTS expressed no opinion as to the prices or ranges of prices at which shares of securities of any person, including shares of the Metacrine common stock or the Equillium common stock, will trade at any time, including following the announcement or consummation of the Merger. MTS was not requested to opine as to, and the September MTS Opinion did not in any manner address, the amount or nature of compensation to any of the officers, directors or employees of any party to the Merger, or any class of such persons, relative to the compensation to be paid to the holders of Metacrine common stock in connection with the Merger or with respect to the fairness of any such compensation.
In accordance with customary investment banking practice, MTS employed generally accepted valuation methods in reaching its opinion. The September MTS Opinion was reviewed and approved by a fairness committee of MTS.
Summary of Financial Analysis
MTS performed a variety of financial analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not susceptible to partial analysis or summary description. In arriving at its opinion, MTS considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusions MTS reached were based on all the analyses and factors presented, taken as a whole, and also on application of MTS's own experience and judgment. Such conclusions may involve significant elements of subjective judgment and qualitative analysis.
MTS therefore gave no opinion as to the value or merit standing alone of any one or more parts of the analyses. No company or transaction used in any analysis for purposes of comparison was identical to Metacrine or Equillium. Accordingly, an analysis of the results of the comparisons was not mathematical; rather, it involved complex considerations and judgments about differences in the companies and transactions to which Metacrine or Equillium was compared and other factors that could affect the public trading value or transaction value of the companies. Furthermore, MTS believes that the summary provided and the analyses described below must be considered as a whole and that selecting any portion of the analyses, without considering all of them, would create an incomplete view of the process underlying MTS’s analysis and opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described below should not be taken to be the view of MTS with respect to the actual value of Metacrine, Equillium or shares of Metacrine common stock or Equillium common stock.
Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of the corresponding summaries and are alone not a complete description of the financial analyses performed by MTS. Considering the data in the tables below without considering the corresponding full narrative descriptions of the financial analyses, including the methodologies and assumptions underlying such analyses, could create a misleading or incomplete view of the financial analyses performed by MTS.
In performing its analyses, MTS made numerous assumptions with respect to industry performance, general business, regulatory and economic conditions and other matters, all of which are beyond MTS’s control and many of which are beyond the control of Metacrine and/or Equillium. Any estimates used by MTS in its analysis are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

TABLE OF CONTENTS

MTS performed standalone valuation analyses of both Metacrine and Equillium using a variety of valuation methodologies, as described below. MTS then performed a relative valuation analysis in order to compare the Exchange Ratio to be employed in the Merger, to the range of exchange ratios implied based on the respective standalone valuation ranges. MTS also analyzed the performance of the pro forma combined company and each of Metacrine’s and Equillium’s contribution thereto. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before September 1, 2022, and is not necessarily indicative of current market conditions.
Metacrine Valuation Analysis
Liquidation Analysis
At the direction of Metacrine, MTS assumed that the only material assets of Metacrine were its cash, that no other assets of Metacrine have any material value, and that Metacrine does not currently, and does not intend in the future to, conduct any activity that may result in the generation of revenue. Metacrine instructed MTS to assign meaningful value only to Metacrine’s Net Cash. In connection therewith, MTS was advised by Metacrine that Metacrine’s Net Cash alone is not sufficient to support Metacrine as a standalone entity going forward, and based on such direction from Metacrine and with the consent of the Metacrine Board, MTS analyzed the relevant intrinsic valuation of Metacrine solely using a liquidation analysis, which includes the monetization of the foregoing assets to estimate a sum-of-the-parts value in a potential liquidation. Correspondingly, MTS reviewed and relied upon Metacrine management’s assumptions on liquidation costs for purposes of a liquidation analysis to value Metacrine.
MTS computed the total equity value of Metacrine in a liquidation to be approximately $27.3 million, calculated as approximately $55.5 million of cash as of June 30, 2022, less wind-down costs of approximately $29.5 million, plus an assumed upfront cash value from Metacrine’s licensing deal relating to the HSD program of $1.25 million, as compared to the then-current market capitalization of Metacrine of approximately $20.6 million. The analysis assumed a liquidation date of November 30, 2022, that all wind-down costs were paid in full, employees were severed by November 30, 2022, all employee-related restructuring and severance costs are paid in full, and, to be conservative, that no funds were retained in reserve for unknown or contingent liabilities. MTS estimated a liquidation value of approximately $27.3 million to Metacrine stockholders in a potential liquidation, or $0.58 per share.
Historical Stock Price Performance
MTS also reviewed for informational purposes only the share price trading history of Metacrine common stock for the period beginning on October 22, 2021, the date that Metacrine announced its strategic reprioritization, and ending on September 1, 2022. During this period, shares of Metacrine common stock traded as low as $0.36 per share and as high as $1.63 per share, compared to the closing price of Metacrine common stock on September 1, 2022 of $0.45 per share.
In addition, MTS reviewed the volume-weighted average trading price, or the VWAP, over the 5 trading day, 20 trading day, 60 trading day, last six month, and last twelve month periods ending on September 1, 2022, and since Metacrine’s initial public offering, or IPO. These VWAPs are set forth in the table below:

Metacrine instructed MTS to ascribe no value to Metacrine’s ongoing operations for the purposes of valuing Metacrine. The share price trading history and volume weighted average trading prices were provided to the Metacrine board of directors for informational purposes only and were not relied upon by MTS for valuation purposes.

TABLE OF CONTENTS

Equillium Valuation Analysis
MTS analyzed the valuation of Equillium using two different methodologies: a discounted cash flow analysis and a public trading comparable companies analysis, utilizing companies, which MTS deemed relevant. The results of each of these analyses are summarized below.
Equillium Discounted Cash Flow Analysis—Overview
MTS performed discounted cash flow analyses of Equillium by calculating, based on the September Opinion Projections, the estimated present value of Equillium’s discounted cash flows and terminal value in two cases, as of November 30, 2022 and as of December 31, 2022. In the November 30, 2022 case, at Metacrine management’s direction and based on the belief of Metacrine’s Board and management, MTS assumed a risk-adjusted illustrative partnership (at 75% POS) for itolizumab that conservatively assumed no upfront payment but full reimbursement of research and development, or R&D, expense and a set of milestones upon successful development. In the December 31, 2022 case, MTS assumed, at Metacrine management’s direction and based on the belief of Metacrine’s Board and management, that illustrative partnership is consummated (100% POS). In each of those two cases, also at the direction and belief of Metacrine, MTS employed the following POS assumptions: (i) 60% cumulative regulatory POS for itolizumab in aGVHD, (ii) 30% cumulative regulatory POS for itolizumab in lupus nephritis, (iii) 20% cumulative regulatory POS for itolizumab in ulcerative colitis, and (iv) 20% cumulative regulatory POS for EQ101 in alopecia areata. MTS conducted certain sensitivity analyses for purposes of its discounted cash flow analyses to derive an implied per share discount back to November 30, 2022 and December 31, 2022, based upon (i) a weighted average cost of capital ranging from 13.5% to 17.5% based upon MTS’s analysis of the cost of capital for Equillium’s publicly traded comparable companies universe, and (ii) a cumulative itolizumab aGVHD POS range of 40% to 80%.
Discounted Cash Flow Analysis—September Opinion Projections
MTS discounted two sets of analyses using a present value as of (a) November 30, 2022 and (b) December 31, 2022, estimating the Unlevered Free Cash Flow (earnings before interest and taxes, or EBIT, less income tax expense, plus depreciation and amortization, less changes in working capital, less capital expenditures) that Equillium will generate during the period through December 31, 2038, calculated by MTS based on the September Opinion Projections, and taking into account the sensitivity metrics described above, and assuming no terminal value. The estimates of the Unlevered Free Cash Flow were then discounted to present values using a range of discount rates based on Equillium’s estimated weighted average cost of capital. An implied per share value was calculated based on Equillium’s current capitalization, as provided by Equillium’s management.
The following table reflects the ranges of implied price per share of Equillium implied by this discounted cash flow analysis for each sensitivity metric described above and using the range of discount rates based on Equillium’s estimated weighted average cost of capital, rounded to the nearest $0.05, as compared to the current per share value of Equillium of $2.79 as of September 1, 2022:

Public Trading Comparable Companies Analysis
MTS reviewed and compared the projected operating performance of Equillium based on the September Opinion Projections, with publicly available information concerning other publicly traded companies and reviewed the current market price of Equillium common stock and certain publicly traded securities of such other companies. MTS selected the following late-stage autoimmune and/or inflammatory disease publicly traded companies:
KalVista Pharmaceuticals, Inc.
MoonLake Immunotherapeutics
107

TABLE OF CONTENTS

Allakos Inc.
VectivBio Holding AG
Immunic Inc.
Abivax Societe Anonyme
Akari Therapeutics Plc
X4 Pharmaceuticals, Inc.
Applied Molecular Transport Inc.
Although none of the selected companies is directly comparable to Equillium, MTS included these companies in its analysis because they are publicly traded companies with certain characteristics that, for purposes of analysis, may be considered similar to certain characteristics of Equillium.
MTS calculated the relevant range of enterprise values based on a review of the stage of the comparable companies, amount of data, and size of indications (orphan disease indications) to be $59 million (VectivBio Holding AG) to $87 million (Allakos Inc.). MTS calculated the equity value for the selected companies, as of September 1, 2022, by applying the relevant ranges to derive equity valuations of Equillium, after adjusting for net debt, preferred stock and minority interest, as appropriate. An implied value of each share of Equillium common stock was calculated based on Equillium’s capitalization, as provided by Equillium’s management as of June 30, 2022. The table below shows the equity values calculated for the selected comparable companies range as of September 1, 2022, rounded to the nearest $5 million:
Publicly Traded Comparable Company

MTS derived a high-low enterprise value range for the comparable companies, and calculated the implied price per share value range for Equillium by using all of the companies in the above-referenced data set and applying the treasury stock method to Equillium’s dilutive securities. The table below notes the implied price per share value range of Equillium, rounded to the nearest $0.05 per share as compared to the current per share value of Equillium common stock of $2.79 as of September 1, 2022:

While MTS performed this analysis, the share price trading history and volume weighted average trading prices were not relied upon for valuation purposes.
Relative Valuation Analysis
MTS compared the following combinations of Metacrine liquidation value to the low and high per share values of Equillium to determine the implied range of exchange ratios, in terms of the number of shares of Equillium common stock to be received by Metacrine stockholders for each share of Metacrine common stock.
Metacrine Liquidation Per Share Value and Equillium DCF High Per Share Value, as of 11/30/22
Metacrine Liquidation Per Share Value and Equillium DCF Low Per Share Value, as of 11/30/22
Metacrine Liquidation Per Share Value and Equillium DCF High Per Share Value, as of 12/31/22
Metacrine Liquidation Per Share Value and Equillium DCF Low Per Share Value, as of 12/31/22
The table below notes the implied percent ownership of common stock of the pro forma combination by holders of Metacrine common stock resulting from applying the multiple exchange ratios in each of the comparable equity value scenarios described above. The following table sets forth the results of these analyses for the exchange ratio and pro forma ownership, respectively:

MTS compared the above ranges of implied aggregate value exchange ratios to the implied Exchange Ratio of 0.243x and within the context of the collar range of 0.151x and 0.251x, and found that, in all instances, the range of aggregate value exchange ratios implied by the analyses described above was within or below that implied by the Exchange Ratio. MTS also compared the above ranges of Metacrine’s implied pro forma ownership to the pro forma ownership of approximately 25.3% implied by the Exchange Ratio of 0.243x in the transactions contemplated by the Merger Agreement, and found that, in all instances, the range of Metacrine’s pro forma ownership implied by the analyses described above was below that implied by the Exchange Ratio.
Pro Forma Combination Analysis and Intrinsic Valuation of Merger Consideration (“Has-Gets” Analysis)
For informational purposes only and not as a component of its fairness analysis, MTS also analyzed the projected performance of the pro forma combination, including projected synergies and an assumed pro forma capital structure, each as provided by Metacrine management as of September 1, 2022. MTS compared the implied value of each share of Metacrine common stock in the pro forma combination, using the full ranges of sensitivities from the standalone discounted cash flow analysis of Equillium, to the implied liquidation value of each share of Metacrine common stock on a standalone basis. MTS compared these values at the high-end of the exchange ratio collar, implied exchange ratio as of September 1, 2022, and the low-end of the exchange ratio collar, assuming an equity value of $32.5 million.

Explanatory Note
Subsequent to MTS’s presentation to the Metacrine Board and the delivery of the September MTS Opinion, Metacrine’s management identified a discrepancy in the fully-diluted shares and the number of such shares used in connection with its preparation of the September MTS Opinion calculation. This discrepancy resulted in slight differences in the calculation of the liquidation value per share of Metacrine common stock, the Exchange Ratio implied by the Merger and the implied offer price per share. The following table identifies these differences:

Upon reviewing the corrected number of shares and the resulting changes to the liquidation value per share of the Metacrine common stock, the Exchange Ratio implied by the Merger and the implied offer price per share, MTS informed the Metacrine Board that, had the correct number of fully-diluted shares of Metacrine common stock been used in its analyses, it would have reached the same conclusion regarding the fairness, from a financial point of view, of the Exchange Ratio to the holders of Metacrine common stock (other than Excluded Shares) as of the date of the September MTS Opinion.
Opinion of Metacrine’s Financial Advisor as of October 19, 2022
As stated above, pursuant to Metacrine's retention of MTS Partners as Metacrine’s financial advisor in connection with the transactions contemplated by the Merger Agreement, MTS rendered its initial oral opinion on September 2, 2022, which was subsequently confirmed by the September MTS Opinion, that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in the September MTS Opinion and described below, the Exchange Ratio employed in the Merger pursuant to the Merger Agreement was fair to the holders of Metacrine common stock (other than holders of Excluded Shares), from a financial point of view. Following MTS’s delivery of the September MTS Opinion, and in light of the status of Equillium’s strategic initiatives, the Metacrine Board requested that MTS render a revised opinion as to the fairness of the Exchange Ratio to the holders of Metacrine common stock (other than holders of Excluded Shares), from a financial point of view. On October 19, 2022, MTS rendered its oral opinion (which was subsequently confirmed by delivery of the October MTS Opinion) that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in the October MTS Opinion and described below, the Exchange Ratio employed in the Merger pursuant to the Merger Agreement was fair to the holders of Metacrine common stock (other than holders of Excluded Shares), from a financial point of view.
The full text of the October MTS Opinion, which sets forth the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by MTS in connection with the October MTS Opinion, is attached as Annex C-2 to this joint proxy statement/prospectus and is incorporated herein by reference. The summary of the October MTS Opinion set forth below in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of the October MTS Opinion. Please read the October MTS Opinion, together with the summary thereof in this joint proxy statement/prospectus, in its entirety.
MTS provided its opinion for the information and assistance of the Metacrine Board in connection with its consideration of the Merger. The October MTS Opinion addressed solely the fairness, from a financial point of view, of the Exchange Ratio employed in the Merger pursuant to the Merger Agreement to the holders of Metacrine common stock (other than holders of Excluded Shares) and does not address any other aspect or implication of the Merger. The October MTS Opinion is not a recommendation to Metacrine’s board of directors or any stockholder of Metacrine as to how to vote or to take any other action in connection with the Merger.
In the course of performing its review and analyses for rendering the October MTS Opinion, MTS:
i.
reviewed the Merger Agreement dated September 6, 2022;

v.
reviewed the October Opinion Projections, and utilized per instruction of Metacrine;
vi.
conducted discussions with members of senior management and representatives of Equillium with respect to the October Opinion Projections;
vii.
compared the trading and valuation metrics of Equillium with publicly available information concerning other publicly-traded companies that MTS deemed relevant;
viii.
reviewed the current and historical market prices of the Metacrine common stock and Equillium common stock, respectively, and certain publicly traded securities of such other companies, in each case, that MTS deemed relevant;
ix.
performed a liquidation analysis of Metacrine based upon information provided to us by management of Metacrine;
x.
reviewed and analyzed, based on the October Opinion Projections, the projected cash flows to be generated by Equillium to determine Equillium’s discounted cash flows; and
xi.
performed such other financial studies, analyses and investigations, and considered such other information, as MTS deemed appropriate for the purposes of the opinion.
In arriving at the October MTS Opinion, MTS assumed and relied upon, without assuming liability or responsibility for independent verification, the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information that was publicly available or was provided to, discussed with or reviewed by MTS and upon the assurances of the management of Metacrine that they are not aware of any material relevant developments or matters related to Metacrine or Equillium, respectively, or that may affect the Merger that have been omitted or that remain undisclosed to MTS. The October MTS Opinion does not address any legal, regulatory, tax, accounting, or financial reporting matters, as to which MTS understands that Metacrine has obtained such advice as it deemed necessary from other advisors, and MTS relied, with Metacrine’s consent, on such assessments made by such other advisors to Metacrine with respect to such matters. MTS did not conduct any independent verification of the October Opinion Projections. Without limiting the generality of the foregoing, with respect to the October Opinion Projections, MTS assumed, with Metacrine’s consent, and based upon discussions with the management of Metacrine, that they have been reasonably prepared (or in the case of the October Opinion Projections, adjusted) by the management of Metacrine in good faith, and that the October Opinion Projections reflected the best currently available estimates and judgments of the management of Metacrine of the future results of operations and financial performance of Equillium. The October Opinion Projections are based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions and, in particular, assumptions regarding increased market volatility and the widespread disruption, extraordinary uncertainty and unusual volatility arising from the effects of the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. Accordingly, actual results could vary significantly from those set forth in the October Opinion Projections. MTS expressed no view as to the October Opinion Projections or the assumptions on which they were based and MTS assumed no responsibility for the accuracy or completeness thereof.
In arriving at the October MTS Opinion, MTS did not make any independent evaluations or appraisals of the assets or liabilities of Metacrine or Equillium or any of their respective subsidiaries, and MTS was not furnished with any such evaluations or appraisals, nor did MTS evaluate the solvency of Metacrine, Equillium or any other entity under any state or federal law relating to bankruptcy, insolvency or similar matters. MTS assumed that there had been no material change in the assets, financial condition, business or prospects of
111

TABLE OF CONTENTS

Metacrine or Equillium since the date of the most recent relevant financial information made available to MTS. Without limiting the generality of the foregoing, MTS undertook no independent analysis of any pending or threatened litigation, regulatory action, possible unasserted claims or other contingent liabilities to which Metacrine, Equillium or any of their respective affiliates is a party or may be subject, and, at the direction of the Metacrine Board and with the Metacrine Board’s consent, the October MTS Opinion made no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. MTS also assumed that neither Metacrine, Equillium, Acquisition Sub or Merger Sub is a party to any material pending transaction that has not been disclosed to MTS, including, without limitation, any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger.
MTS assumed that the representations and warranties of each party contained in the Merger Agreement and in all other related documents and instruments that are referred to therein were true and correct as of the date or the dates made or deemed made, that each party thereto will fully and timely perform all of the covenants and agreements required to be performed by it under the Merger Agreement and any other agreement contemplated thereby, and that the transactions contemplated by the Merger Agreement, including, without limitation, the Merger, will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement. MTS, with the Metacrine Board’s consent, further assumed that any adjustment to the Merger Consideration pursuant to the terms of the Merger Agreement would not result in any adjustment to the Merger Consideration that was material to MTS’s analysis. MTS also assumed that any governmental, regulatory and other consents and approvals contemplated in connection with the Merger would be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions would be imposed or waivers made that would have an adverse effect on Metacrine, Equillium, Acquisition Sub, Merger Sub or the contemplated benefits of the Merger.
The October MTS Opinion was necessarily based on economic, market, financial and other conditions as they existed, and on the information made available to MTS, as of October 19, 2022. MTS did not consider any potential legislative or regulatory changes currently being considered by the United States Congress, the SEC, or any other governmental or regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. It should be understood that, although subsequent developments may affect the conclusion reached in the October MTS Opinion, MTS has no obligation to update, revise or reaffirm the October MTS Opinion. The October MTS Opinion addressed solely the fairness, from a financial point of view and as of the date thereof, of the Exchange Ratio to the holders of Metacrine common stock (other than the Excluded Shares), and did not address any other terms in the Merger Agreement, or any other agreement contemplated by the Merger Agreement or relating to the Merger or any other aspect or implication of the Merger, including, without limitation, the form or structure of the Merger, or the fairness of the Merger or the Exchange Ratio to any other securityholders or creditors or any other constituency of Metacrine, including holders of Company Options (as defined in the Merger Agreement), Company Warrants (as defined in the Merger Agreement) and Company RSUs (as defined in the Merger Agreement) and participations in the ESPP (as defined in the Merger Agreement). The October MTS Opinion did not address Metacrine’s underlying business decision to proceed with the Merger or the relative merits of the Merger compared to other alternatives available to Metacrine. MTS expressed no opinion as to the prices or ranges of prices at which shares of securities of any person, including shares of the Metacrine common stock or the Equillium common stock, will trade at any time, including following the announcement or consummation of the Merger. MTS was not requested to opine as to, and the October MTS Opinion did not in any manner address, the amount or nature of compensation to any of the officers, directors or employees of any party to the Merger, or any class of such persons, relative to the compensation to be paid to the holders of Metacrine common stock in connection with the Merger or with respect to the fairness of any such compensation.
In accordance with customary investment banking practice, MTS employed generally accepted valuation methods in reaching its opinion. The October MTS Opinion was reviewed and approved by a fairness committee of MTS.
Summary of Financial Analysis
MTS performed a variety of financial analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not susceptible to partial analysis or summary description. In arriving at its opinion, MTS considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered. Each analytical technique has inherent strengths and
112

TABLE OF CONTENTS

weaknesses, and the nature of the available information may further affect the value of particular techniques. The overall conclusions MTS reached were based on all the analyses and factors presented, taken as a whole, and also on application of MTS's own experience and judgment. Such conclusions may involve significant elements of subjective judgment and qualitative analysis.
MTS therefore gave no opinion as to the value or merit standing alone of any one or more parts of the analyses. No company or transaction used in any analysis for purposes of comparison was identical to Metacrine or Equillium. Accordingly, an analysis of the results of the comparisons was not mathematical; rather, it involved complex considerations and judgments about differences in the companies and transactions to which Metacrine or Equillium was compared and other factors that could affect the public trading value or transaction value of the companies. Furthermore, MTS believes that the summary provided and the analyses described below must be considered as a whole and that selecting any portion of the analyses, without considering all of them, would create an incomplete view of the process underlying MTS’s analysis and opinion. As a result, the ranges of valuations resulting from any particular analysis or combination of analyses described below should not be taken to be the view of MTS with respect to the actual value of Metacrine, Equillium or shares of Metacrine common stock or Equillium common stock.
Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of the corresponding summaries and are alone not a complete description of the financial analyses performed by MTS. Considering the data in the tables below without considering the corresponding full narrative descriptions of the financial analyses, including the methodologies and assumptions underlying such analyses, could create a misleading or incomplete view of the financial analyses performed by MTS.
In performing its analyses, MTS made numerous assumptions with respect to industry performance, general business, regulatory and economic conditions and other matters, all of which are beyond MTS’s control and many of which are beyond the control of Metacrine and/or Equillium. Any estimates used by MTS in its analysis are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.
MTS performed standalone valuation analyses of both Metacrine and Equillium using a variety of valuation methodologies, as described below. MTS then performed a relative valuation analysis in order to compare the Exchange Ratio to be employed in the Merger, to the range of exchange ratios implied based on the respective standalone valuation ranges. MTS also analyzed the performance of the pro forma combined company and each of Metacrine’s and Equillium’s contribution thereto. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before October 18, 2022, and is not necessarily indicative of current market conditions.
Metacrine Valuation Analysis
Liquidation Analysis (“Has” Analysis)
At the direction of Metacrine, MTS assumed that the only material assets of Metacrine were its cash, that no other assets of Metacrine have any material value, and that Metacrine does not currently, and does not intend in the future to, conduct any activity that may result in the generation of revenue. Metacrine instructed MTS to assign meaningful value only to Metacrine’s Net Cash. In connection therewith, MTS was advised by Metacrine that the Net Cash alone is not sufficient to support Metacrine as a standalone entity going forward and based on such direction from Metacrine and with the consent of the Metacrine Board, MTS analyzed the relevant intrinsic valuation of Metacrine solely using a liquidation analysis, which includes the monetization of the foregoing assets to estimate a sum-of-the-parts value in a potential liquidation. Correspondingly, MTS reviewed and relied upon the October Opinion Projections for purposes of a liquidation analysis to value Metacrine.
MTS computed the total equity value of Metacrine in a liquidation to be approximately $25.7 million, calculated as approximately $52.2 million of cash as of September 30, 2022, less wind-down costs of approximately $25.2 million, plus an assumed upfront cash value from Metacrine’s licensing deal relating to the HSD program of $1.3 million, as compared to the then current market capitalization of Metacrine of approximately $18.3 million. The analysis assumed a liquidation date of December 31, 2022, that all wind-down costs were paid in full, employees were severed by December 31, 2022, all employee-related restructuring and
113

TABLE OF CONTENTS

severance costs are paid in full, other fees and expenses related to executing a liquidation process, and, furthermore, that no funds were retained in reserve for unknown or contingent liabilities. MTS estimated a liquidation value of approximately $25.7 million to Metacrine stockholders in a potential liquidation, or $0.58 per share.
Intrinsic Value of Merger Consideration (“Gets” Analysis)
To compare and contrast what the Metacrine shareholders could have in a “Has” or liquidation scenario (their best alternative to the deal), MTS analyzed the intrinsic valuation of the pro forma company to Metacrine stockholders assuming a pro forma capital structure, as detailed by the Merger Agreement. MTS compared the implied intrinsic value of the merger consideration to Metacrine’s stockholders by multiplying the implied exchange ratio of 0.282x, with the pro forma total combined company implied price per share as calculated in the Pro Forma Combination analysis of the October MTS Opinion. This value was then sensitized across a range of varying WACC percentages and risk-adjustments pertaining to the POS of Equillium’s aGVHD asset. This range of values was then compared to Metacrine’s implied liquidation value per share. A summary of the comparable inputs for each sensitivity analysis is provided below:

Historical Stock Price Performance
MTS also reviewed, for informational purposes only, the share price trading history of Metacrine common stock for the period beginning on October 22, 2021, the date that Metacrine announced its strategic reprioritization, and ending on October 18, 2022. During this period, shares of Metacrine Common Stock traded as low as $0.36 per share and as high as $1.63 per share, compared to the closing price of Metacrine Common Stock on October 18, 2022, of $0.38 per share.
In addition, MTS Securities reviewed the VWAP over the 5 trading day, 20 trading day, 60 trading day, last six month, and last twelve month periods ending on October 18, 2022, and since Metacrine’s IPO. These VWAPs are set forth in the table below:

Metacrine instructed MTS to ascribe no value to Metacrine’s ongoing operations for the purposes of valuing Metacrine. The share price trading history and volume weighted average trading prices were provided to the Metacrine Board for informational purposes only and were not relied upon by MTS for valuation purposes.
Equillium Valuation Analysis
MTS analyzed the valuation of Equillium using two different methodologies: a discounted cash flow analysis and a public trading comparable companies analysis, utilizing companies, which MTS deemed relevant. The results of each of these analyses are summarized below.
Equillium Discounted Cash Flow Analysis—Overview
MTS performed discounted cash flow analyses of Equillium by calculating, based on the October Opinion Projections, the estimated present value of Equillium’s discounted cash flows and valuation date as of December 31, 2022. MTS assumed, at Metacrine management’s direction and based on the belief of Metacrine’s
114

TABLE OF CONTENTS

Board and management, that the illustrative partnership is not consummated. MTS also employed the following POS assumptions at the direction and belief of Metacrine: (i) 60% cumulative regulatory POS for itolizumab in aGVHD, (ii) 60% cumulative regulatory POS for itolizumab in lupus nephritis, (iii) 20% cumulative regulatory POS for itolizumab in ulcerative colitis, and (iv) 20% cumulative regulatory POS for EQ101 in alopecia areata. MTS conducted certain sensitivity analyses for purposes of its discounted cash flow analyses to derive an implied per share discounted back to December 31, 2022, based upon (i) a weighted average cost of capital ranging from 14.0% to 18.0% based upon MTS’s analysis of the cost of capital for Equillium’s publicly traded comparable companies universe, and (ii) a cumulative itolizumab aGVHD POS range of 40% to 80%.
Discounted Cash Flow Analysis—October Opinion Projections
MTS discounted two sets of analyses using a present value as of December 31, 2022, (i) estimates of the Unlevered Free Cash Flow (earnings before interest and taxes, or EBIT, less income tax expense, plus depreciation and amortization, less changes in working capital, less capital expenditures) that Equillium will generate during the period through December 31, 2038, calculated by MTS based on the October Opinion Projections, and taking into account the sensitivity metrics described above, and assuming no terminal value. The estimates of the Unlevered Free Cash Flow were then discounted to present values using a range of discount rates based on Equillium’s estimated weighted average cost of capital. An implied per share value was calculated based on Equillium’s current capitalization, as provided by Equillium’s management.
The following table reflects the ranges of implied price per share of Equillium implied by this discounted cash flow analysis for each sensitivity metric described above and using the range of discount rates based on Equillium’s estimated weighted average cost of capital, rounded to the nearest $0.05, as compared to the current per share value of Equillium of $1.74 as of October 18, 2022:

$7.00 – $15.10
Public Trading Comparable Companies Analysis
MTS reviewed and compared the projected operating performance of Equillium based on the October Opinion Projections, with publicly available information concerning other publicly traded companies and reviewed the current market price of Equillium common stock and certain publicly traded securities of such other companies. MTS selected the following late-stage autoimmune and/or inflammatory disease publicly traded companies:
KalVista Pharmaceuticals, Inc.
MoonLake Immunotherapeutics
VectivBio Holding AG
Immunic Inc.
Abivax Societe Anonyme
Akari Therapeutics Plc
X4 Pharmaceuticals, Inc.
Applied Molecular Transport Inc.
Although none of the selected companies is directly comparable to Equillium, MTS included these companies in its analysis because they are publicly traded companies with certain characteristics that, for purposes of analysis, may be considered similar to certain characteristics of Equillium.
MTS calculated the relevant range of enterprise values based on a review of the stage of the comparable companies, amount of data, and size of indications (orphan disease indications) to be from $79 million (Akari Therapeutics Plc) to $128 million (X4 Pharmaceuticals, Inc.). MTS calculated the equity value for the selected companies, as of October 18, 2022, by applying the relevant ranges to derive equity valuations of Equillium,
115

TABLE OF CONTENTS

after adjusting for net debt, preferred stock and minority interest, as appropriate. MTS also calculated an implied value of each share of Equillium common stock based on Equillium’s capitalization, as provided by Equillium’s management as of June 30, 2022. The table below shows the equity values calculated for the selected comparable companies range as of October 18, 2022, rounded to the nearest $5 million:

MTS derived a high-low enterprise value range for the comparable companies, and calculated the implied price per share value range for Equillium by using all of the companies in the above-referenced data set and applying the treasury stock method to Equillium’s dilutive securities. The table below notes the implied price per share value range of Equillium, rounded to the nearest $0.05 per share as compared to the current per share value of Equillium common stock of $1.74 as of October 18, 2022:

MTS also reviewed for informational purposes only the share price trading history of Equillium common stock for the 52-week period ending October 18, 2022. During this period, shares of Equillium common stock traded as low as $1.66 per share and as high as $6.84 per share, compared to the closing price of Equillium common stock on October 18, 2022 of $1.74.
In addition, MTS reviewed the VWAP over the 5 trading day, 20 trading day, 60 trading day, last six month, last twelve month, and last two year periods ending on October 18, 2022. These VWAPs are set forth in the table below:

While MTS performed this analysis, the share price trading history and volume weighted average trading prices were not relied upon for valuation purposes.
Relative Valuation Analysis
MTS compared the following combinations of Metacrine liquidation value to the low and high per share values of Equillium to determine the implied range of exchange ratios, in terms of the number of shares of Equillium common stock to be received by Metacrine stockholders for each share of Metacrine common stock.
Metacrine Liquidation Per Share Value and Equillium DCF High Per Share Value, as of 12/31/22
Metacrine Liquidation Per Share Value and Equillium DCF Low Per Share Value, as of 12/31/22

The table below notes the implied percent ownership of common stock of the pro forma combination by holders of Metacrine common stock resulting from applying the multiple exchange ratios in each of the comparable equity value scenarios described above. The following table sets forth the results of these analyses for the exchange ratio and pro forma ownership, respectively:

MTS compared the above ranges of implied aggregate value exchange ratios to the implied Exchange Ratio of 0.282x and within the context of the collar range of 0.169x and 0.282x, and found that, in all instances, the range of aggregate value exchange ratios implied by the analyses described above was within or below that implied by the Exchange Ratio. MTS also compared the above ranges of Metacrine’s implied pro forma ownership to the pro forma ownership of approximately 26.7% implied by the Exchange Ratio of 0.282x in the transactions contemplated by the Merger Agreement, and found that, in all instances, the range of Metacrine’s pro forma ownership implied by the analyses described above was below that implied by the Exchange Ratio.
Pro Forma Combination Analysis and Intrinsic Value of Merger Consideration (“Has-Gets” Analysis)
In order to analyze the value of the Merger Consideration, MTS first analyzed the projected performance of the pro forma combination, including projected synergies and an assumed pro forma capital structure, as detailed in the Merger Agreement. A summary of the total pro forma analysis on an equity value and per share value are provided below, rounded to the nearest $5 million and $0.05 per share:

$6.30 - $12.70
As of October 18, 2022, Equillium’s 10-Day VWAP of $1.90 was trading below the collar floor of $2.70. As a result, this analysis assumed Equillium would issue shares to Metacrine stockholders at $2.70 per share, calculated as Metacrine’s implied Merger Consideration value of $33.8 million divided by $2.70, and resulting in the issuance of approximately 12.5 million shares of Equillium common stock.
The equity value of the total combined pro forma company was calculated by adding cash and subtracting debt from the net present value of the projection period. Implied total pro forma price per share was then calculated based on the pro forma fully diluted shares outstanding. The implied pro forma per share value to Metacrine was then calculated by multiplying the implied offer exchange ratio of 0.282x to the total implied pro forma price per share.
MTS Opinions—Miscellaneous
The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to summary description. In arriving at its opinions, MTS did not draw, in isolation, conclusions from or with regard to any factor or analysis that it considered. Rather, MTS made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of the analyses.
The MTS Opinions were one of the many factors taken into consideration by the Metacrine Board in making its determination to approve and reaffirm the Merger Agreement. Consequently, the analyses as described above should not be viewed as determinative of the opinion of the Metacrine Board with respect to the Exchange Ratio for the shares of Metacrine common stock in the Merger or of whether the Metacrine Board would have been willing to agree to a different exchange ratio. The Exchange Ratio for the shares of Metacrine common
117

TABLE OF CONTENTS

stock in the Merger was determined through arm's-length negotiations between Metacrine and Equillium and was approved by the Metacrine Board. MTS and its affiliates provided advice to Metacrine during these negotiations. However, neither MTS nor any of its affiliates recommended any specific exchange ratio to Metacrine or the Metacrine Board or that any specific exchange ratio constituted the only appropriate exchange ratio for the Merger.
MTS has consented to the use of the MTS Opinions in this joint proxy statement/prospectus; however, MTS has not assumed any responsibility for the form or content of this joint proxy statement/prospectus, other than the MTS Opinions themselves.
MTS and its affiliates, as part of their investment banking services, are regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, and for other purposes. As noted above, MTS Partners acted as exclusive financial advisor to Metacrine in connection with the Merger and participated in certain of the negotiations leading to the Merger Agreement. Metacrine selected MTS Partners as its exclusive financial advisor because it is nationally recognized in the healthcare and biotechnology industries as having investment banking professionals with significant experience in healthcare and biotechnology investment banking and merger and acquisition transactions.
Pursuant to an engagement letter agreement, dated as of September 27, 2021, between Metacrine and MTS Partners, Metacrine engaged MTS Partners to act as its exclusive financial advisor in connection with Metacrine’s consideration, evaluation and/or exploration of certain potential merger and acquisition transactions or similar transactions. As permitted by the terms of the engagement letter and pursuant to MTS Partners’ internal policies, MTS, a wholly owned subsidiary of MTS Partners delivered the MTS Opinion. As compensation for MTS Partners and its affiliates’ financial advisory services, Metacrine paid a nonrefundable retainer fee of $250,000 in connection with the execution of such engagement letter and paid additional fees of $300,000 for rendering the September MTS Opinion and $150,000 for rendering the October MTS Opinion, each in connection with the Board’s consideration of the proposed transaction with Equillium, which fees were not contingent upon the successful completion of the Offer or the Merger or the conclusion reached in the MTS Opinions. Upon the consummation of the Offer, Metacrine will be obligated to pay to MTS Partners a fee equal to approximately $2.0 million, with all fees previously paid by Metacrine pursuant to the engagement letter credited towards such amount, including the fee paid by Metacrine upon delivery of the MTS Opinions. In addition, Metacrine has agreed to reimburse MTS Partners and its affiliates for their reasonable and documented out-of-pocket expenses incurred, and to indemnify MTS Partners and its related persons for certain liabilities that may arise, in each case, in connection with any of the matters contemplated by the engagement letter.
Except as noted above, neither MTS nor MTS Partners has had a material relationship with, or otherwise received fees from, Metacrine or Equillium or any other parties to the Merger Agreement during the two years preceding the date of each of the September MTS Opinion and October MTS Opinion. MTS, MTS Partners and their affiliates may seek to provide investment banking or financial advisory services to Metacrine and Equillium and/or certain of their respective affiliates in the future and would expect to receive fees for the rendering of any such services.
Financial Interests of Equillium Directors and Executive Officers in the Merger
None of Equillium’s executive officers or members of the Equillium Board is party to an arrangement with Equillium, or participates in any Equillium plan, program or arrangement, that provides such executive officer or trustee with financial incentives that are contingent upon the consummation of the Merger. Equillium’s directors and executive officers will continue as the directors and executive officers of Equillium as of immediately after completion of the Merger. Information about Equillium’s directors and executive officers can be found in Equillium’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as amended and as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are incorporated by reference into this joint proxy statement/prospectus.
Financial Interests of Metacrine Directors and Executive Officers in the Merger
In considering the recommendation of the Metacrine Board in favor of the Merger, you should be aware that Metacrine's directors and executive officers may have interests in the Merger that are different from, or in addition to, the interests of Metacrine's stockholders generally. The Metacrine Board was aware of these interests and considered them, among other matters, in approving the Merger Agreement and the Merger. Metacrine

stockholders should take these interests into account in deciding whether to vote for adoption of the Merger Agreement and thereby approve the Merger. As described in more detail below, these interests include:
At the effective time of the Merger, each Metacrine option and Metacrine RSU will receive the treatment described in the section entitled “Treatment of Metacrine Equity Awards and Warrants” beginning on page 70 of this joint proxy statement/prospectus;
The expectation that following the Closing, Dr. Klassen will be appointed Equillium’s Board and be entitled to receive compensation for his services as a member of Equillium’s Board as further described below under the heading “Future Arrangements with Equillium”;

(1)
The accelerated vesting numbers below assume, if applicable, that a qualifying termination of employment occurs at the effective time of the Merger.
(2)
The executive officer’s equity awards are eligible for the acceleration rights described below under the heading “Existing Change in Control Severance Arrangements.”
(3)
In accordance with the terms of the director’s equity award agreements, unvested equity awards will accelerate vesting in full at the effective time of the Merger. The dollar value of acccelerated options and RSUs is calculated based on the number of shares covered by the applicable Metacrine option or Metacrine RSU that are accelerating multiplied by $0.47 per share, which amount is the average closing market price of the Metacrine common stock for the first 5 business days following the first public announcement of the Merger on September 6, 2022.
Existing Change in Control Severance Arrangements
Severance Plan. Dr. Klassen and Mr. York are eligible to participate in the Metacrine Severance Plan, which provides for severance benefits subject to execution and effectiveness of a release of claims. In the event of a covered termination, which is either a termination without cause (and other than as a result of death or disability) or a resignation for good reason, that occurs during the time period commencing three months prior to and ending 12 months following a change in control, Dr. Klassen will be entitled to a lump sum cash payment equal to 18 months of base salary plus an annual target cash bonus, up to 18 months of payment for continued group health plan benefits and full vesting acceleration of all outstanding equity awards, and Mr. York will be entitled to a lump sum cash payment equal to 12 months of base salary plus an annual target cash bonus, up to 12 months of payment for continued group health plan benefits and full vesting acceleration of all outstanding equity awards.
In addition, the Metacrine Severance Plan provides that in the event of a covered termination that occurs outside of the change in control period, Dr. Klassen will be entitled to a lump sum cash payment equal to 12 months of base salary and up to 12 months of payment for continued group health plan benefits and Mr. York will be entitled to a lump sum cash payment equal to 9 months of base salary and up to 9 months of payment for continued group health plan benefits.
Future Arrangements with Equillium
It is expected that the services of each of our directors and executive officers will terminate at the effective time of the Merger. To our knowledge, except for Dr. Klassen serving as the Metacrine designated director on Equillium’s Board following the closing of the Merger in accordance with the Merger Agreement, no employment, equity contribution or other written agreement between any executive officer or director of Metacrine, on the one hand, and Equillium or its affiliates, on the other hand, existed as of the date of this registration statement, and the Merger is not conditioned upon any executive officer or director of Metacrine entering into any such agreement, arrangement or understanding.
Following the Effective Time, it is expected that Dr. Klassen will be appointed to the Equillium Board. In connection with his continued service, Dr. Klassen will be eligible for compensation in accordance with the Equillium Non-Employee Director
120

TABLE OF CONTENTS

Compensation Policy, or the Equillium non-employee director compensation program. In accordance with that program, Dr. Klassen is expected to receive an annual cash retainer of $42,000, payable in arrears quarterly with the first quarterly payment pro-rated, and, subject to his appointments, if any, any chairman or committee member retainer fees provided for under the program. Upon joining the Equillium Board, Dr. Klassen will also be eligible for an option grant covering 40,000 shares vesting monthly over a three-year period and, subject to his continued service on the Equillium Board through each subsequent stockholder meeting, an option grant covering 20,000 vesting monthly over a one-year period.
It is possible that members of Metacrine’s current management team will enter into new employment or consulting arrangements with Equillium or its affiliates, with any such arrangements to become effective after the Merger is completed, if at all. There can be no assurance that the applicable parties will reach an agreement on any terms, or at all.
Golden Parachute Compensation
This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation for each of Metacrine’s named executive officers that is based on or otherwise relates to the Merger. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules. The amounts set forth in the table below are estimates based on multiple assumptions that may or may not actually occur, including assumptions described in this registration statement and in the footnotes to the table. As a result, the actual amounts, if any, that a named executive officer receives may materially differ from the amounts set forth in the table.
The table below assumes that: (i) the effective time of the Merger will occur on December 23, 2022 (which is the assumed closing date of the Merger solely for purposes of this joint proxy statement/prospectus, including this golden parachute compensation disclosure); (ii) the employment of the named executive officer will be terminated immediately upon the effective time of the Merger on such date in a manner entitling the named executive officer to receive the severance benefits; (iii) no named executive officer receives any additional equity grants on or prior to the effective time of the Merger; (iv) no named executive officer enters into new agreements or is otherwise legally entitled to, prior to the effective time of the Merger, additional compensation or benefits, (v) no withholding taxes are applicable to any of the payments or benefits; and (vi) no payments are delayed due to Section 409A of the Code. Pursuant to applicable proxy disclosure rules, the value of the equity award acceleration below is calculated based on the number of shares covered by the applicable Metacrine option or Metacrine RSU that are accelerating multiplied by $0.47 per share, which amount is the average closing market price of the Metacrine common stock for the first 5 business days following the first public announcement of the Merger on September 6, 2022. The amounts shown in the table do not include the value of payments or benefits that would have been earned, or any amounts associated with equity awards that would vest pursuant to their terms, on or prior to the effective time of the Merger, or the value of payments or benefits that are not based on or otherwise related to the Merger.
In the footnotes to the amounts shown in the table below, we refer to payments that are conditioned on the occurrence of both the Merger as well as the named executive officer's qualifying termination of employment as being payable on a “double-trigger” basis and we refer to payments that are conditioned only upon the occurrence of the Merger as being payable on a “single-trigger” basis. The individuals named below represent the named executive officers as of the date of this joint proxy statement/prospectus.

(1)
Each of Patricia Millican, Catherine Lee, and Hubert Chen, M.D. served as executive officers for a time during the period beginning with the 2021 fiscal year. The service relationship of each has terminated prior to the Merger, and each is currently ineligible to participate in the Metacrine Severance Plan and to receive any benefits based on or otherwise relating to the Merger other than as a stockholder.
(2)
The estimated amount for each named executive officer represents the “double-trigger” cash severance payments to which the named executive officer is expected to become entitled under the Metacrine Severance Plan in connection with a qualifying termination during the change of control period, as described in further detail in the section of this joint proxy statement/prospectus captioned “- Financial Interests of Metacrine Directors and Executive Officers in the Merger -  Existing Change in Control Severance Arrangements.” The estimated amounts represent a lump sum cash payment equal to the sum of (a) each named executive officer’s base salary for 18 months in the case of Dr. Klassen and 12 months in the case of Mr. York; and (b) each named executive officer’s target annual bonus for the year of termination, based on the annual base salary and target annual bonus amount in effect as of September 2022. The following table sets forth the value of each of the base salary and target annual bonus opportunity severance benefits that may become payable to a named executive officer under the terms of the Metacrine Severance Plan.

The estimated amounts in this column include the value of “double-trigger” vesting acceleration of the unvested portion of each named executive officer’s outstanding Metacrine options and Metacrine RSUs to which the named executive officer is expected to become entitled under the Metacrine Severance Plan in connection with a qualifying termination during the change of control period, as described in further detail in the section of this joint proxy statement/prospectus captioned “- Financial Interests of Metacrine Directors and Executive Officers in the Merger -  Existing Change in Control Severance Arrangements.”
With respect to Metacrine RSUs, the estimated amounts in this column represent unvested Metacrine RSUs covering a total of 842,211 shares of Metacrine common stock for Dr. Klassen and 210,553 shares of Metacrine common stock for Mr. York as of September 15, 2022.
With respect to Metacrine options, the estimated amounts in this column represent unvested Metacrine options covering a total of 1,416,485 shares of Metacrine common stock for Dr. Klassen and 445,553 shares of Metacrine common stock for Mr. York as of September 15, 2022. Because the Metacrine options for Dr. Klassen and Mr. York have a per share exercise price that is equal to or greater than $0.47 per share, such options have no value.
(4)
The estimated amounts in this column represent, for each named executive officer, company-paid continuation of post-employment, group health coverage for 18 months in the case of Dr. Klassen and 12 months in the case of Mr. York. These amounts are a “double-trigger” severance benefit to which each named executive officer may become entitled to receive under the Metacrine Severance Plan in connection with a qualifying termination of such named executive officer’s employment during the change of control period, as described in further detail in the section of this joint proxy statement/prospectus captioned “- Financial Interests of Metacrine Directors and Executive Officers in the Merger -  Existing Change in Control Severance Arrangements,” and such amounts are based on coverage in effect as of September 2022.
Accounting Treatment
Equillium determined the Merger constitutes an acquisition of assets instead of a business combination as substantially all of the fair value of the gross assets acquired was concentrated in a group of similar identifiable assets, and therefore, the acquisition was not considered a business. Asset acquisitions are accounted for by allocating the cost of the acquisition, including transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis without recognition of goodwill.
Listing of Equillium common stock
It is a condition to the completion of the Merger that the Equillium common stock issuable in connection with the Merger be approved for listing on the Nasdaq.
Delisting and Deregistration of Metacrine common stock
When the Merger is completed, the Metacrine common stock currently listed on the Nasdaq will cease to be quoted on the Nasdaq and will be deregistered under the Exchange Act.
Appraisal Rights
Under Delaware law, the Metacrine stockholders are not entitled to appraisal rights in connection with the Merger or any other transaction contemplated by the Merger Agreement.
Under Delaware law, the Equillium stockholders are not entitled to appraisal rights in connection with the issuance of shares of Equillium common stock in the Merger pursuant to the terms of the Merger Agreement.

TABLE OF CONTENTS

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES
The following discussion is a summary of the material U.S. federal income tax consequences of the Merger that may be relevant to U.S. Holders and Non-U.S. Holders (each as defined below) of shares of Metacrine common stock whose shares are converted into the right to receive the Merger consideration pursuant to the Merger. This discussion is based upon the Internal Revenue Code of 1986, or the Code, Treasury Regulations promulgated under the Code, court decisions, published positions of the Internal Revenue Service, or the IRS, and other applicable authorities, all as in effect on the date of this joint proxy statement/prospectus and all of which are subject to change or differing interpretations, possibly with retroactive effect. This discussion is limited to holders who hold their shares of Metacrine common stock as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment purposes).
This discussion is for general information only and does not address all of the tax consequences that may be relevant to holders in light of their particular circumstances. For example, this discussion does not address:
tax consequences that may be relevant to holders who may be subject to special treatment under U.S. federal income tax laws, such as financial institutions; tax-exempt organizations; S corporations, partnerships and any other entity or arrangement treated as a partnership or pass-through entity for U.S. federal income tax purposes; insurance companies; mutual funds; dealers in stocks and securities; traders in securities that elect to use the mark-to-market method of accounting for their securities; regulated investment companies; real estate investment trusts; entities subject to the U.S. anti-inversion rules; holders who hold their common stock as “qualified small business stock” for purposes of Sections 1045 and 1202 of the Code; or certain former citizens or long-term residents of the United States;
tax consequences to holders holding the shares as part of a hedging, constructive sale or conversion, straddle or other risk reduction transaction;
tax consequences to holders who received their shares of Metacrine common stock in a compensatory transaction or pursuant to the exercise of options or warrants or whose common stock is subject to employment-based vesting;
tax consequences to U.S. Holders whose “functional currency” is not the U.S. dollar;
tax consequences to holders who hold their common stock through a bank, financial institution or other entity, or a branch thereof, located, organized or resident outside the United States;
tax consequences arising from the Medicare tax on net investment income;
tax consequences to holders subject to special tax accounting rules as a result of any item of gross income with respect to the shares of Metacrine common stock being taken into account in an “applicable financial statement” (as defined in the Code);
the U.S. federal estate, gift or alternative minimum tax consequences, if any; or
any territory, state, local or non-U.S. tax consequences.
If a partnership (including an entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of shares of Metacrine common stock, then the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partner and the partnership. Partnerships holding shares of Metacrine common stock and partners therein should consult their tax advisors regarding the consequences of the Merger.
No ruling has been or will be obtained from the IRS regarding the U.S. federal income tax consequences of the Merger described below. If the IRS contests a conclusion set forth herein, no assurance can be given that a holder would ultimately prevail in a final determination by a court.
THIS DISCUSSION IS PROVIDED FOR GENERAL INFORMATION ONLY AND DOES NOT CONSTITUTE LEGAL ADVICE TO ANY HOLDER. A HOLDER SHOULD CONSULT ITS OWN TAX ADVISORS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES RELATING TO THE MERGER IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES AND ANY CONSEQUENCES ARISING UNDER FEDERAL NON-INCOME TAX LAWS OR THE LAWS OF ANY TERRITORY, STATE, LOCAL OR NON-U.S. TAXING JURISDICTION.
123

TABLE OF CONTENTS

U.S. Holders
For purposes of this discussion, a “U.S. Holder” is a beneficial owner of shares of Metacrine common stock that is for U.S. federal income tax purposes:
an individual who is a citizen or resident of the United States;
a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia;
an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or
a trust that (1) is subject to the primary supervision of a court within the United States and the control of one or more United States persons as defined in section 7701(a)(30) of the Code; or (2) has a valid election in effect under applicable Treasury regulations to be treated as a United States person.
The receipt of Merger consideration by a U.S. Holder in exchange for shares of Metacrine common stock pursuant to the Merger is expected to be a taxable transaction for U.S. federal income tax purposes. In general, such U.S. Holder’s gain or loss will be equal to the difference, if any, between the fair market value of the Merger consideration received and the U.S. Holder’s adjusted tax basis in the shares surrendered pursuant to the Merger. A U.S. Holder’s adjusted tax basis generally will equal the amount that such U.S. Holder paid for the shares. Such gain or loss will be capital gain or loss and will be long-term capital gain or loss if such U.S. Holder’s holding period in such shares is more than one year at the time of the completion of the Merger. A reduced tax rate on capital gain generally will apply to long-term capital gain of a non-corporate U.S. Holder (including individuals). The deductibility of capital losses is subject to limitations. If a U.S. Holder acquired different blocks of shares of Metacrine common stock at different times and different prices, such holder must determine its adjusted tax basis and holding period separately with respect to each block of Metacrine common stock.
Non-U.S. Holders
General
For purposes of this discussion, the term “Non-U.S. Holder” means a beneficial owner of shares of Metacrine common stock that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.
Subject to the discussion below relating to FATCA, any gain realized by a Non-U.S. Holder pursuant to the Merger generally will not be subject to U.S. federal income tax unless:
the gain is effectively connected with a trade or business of such Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment maintained by such Non-U.S. Holder in the United States), in which case such gain generally will be subject to U.S. federal income tax at rates generally applicable to U.S. persons, and, if the Non-U.S. Holder is a corporation, such gain may also be subject to the branch profits tax at a rate of 30 percent (or a lower rate under an applicable income tax treaty);
such Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the completion of the Merger, and certain other specified conditions are met, in which case such gain will be subject to U.S. federal income tax at a rate of 30 percent (or a lower rate under an applicable income tax treaty); or
Metacrine is or has been a “United States real property holding corporation” as such term is defined in Section 897(c) of the Code, or USRPHC, at any time within the shorter of the five-year period preceding the Merger or such Non-U.S. Holder’s holding period with respect to the applicable shares of Metacrine common stock, or the relevant period, and, if shares of Metacrine common stock are regularly traded on an established securities market (within the meaning of Section 897(c)(3) of the Code), such Non-U.S. Holder owns (directly, indirectly or constructively) more than five percent of Metacrine common stock at any time during the relevant period, in which case such gain will be subject to U.S. federal income tax at rates generally applicable to U.S. persons (as described in the first bullet point above), except that the branch profits tax will not apply. Generally, a corporation is a USRPHC if the fair market value of its U.S. real property interests (as defined in the Code) equals or exceeds 50 percent of the sum of the fair market value of its worldwide real property interests plus its
124

other assets used or held for use in a trade or business. For this purpose, U.S. real property interests generally include land, improvements and associated personal property. Although there can be no assurances in this regard, we believe that we are not, and have not been, a USRPHC at any time during the five-year period preceding the Merger. Non-U.S. Holders are encouraged to consult their own tax advisors regarding the possible consequences to them if we are a USRPHC.
Withholding on Foreign Entities
Sections 1471 through 1474 of the Code, and the Treasury regulations and administrative guidance issued thereunder, or FATCA, impose a U.S. federal withholding tax of 30 percent on certain payments made to a “foreign financial institution” (as specially defined under these rules) unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding certain U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or an exemption applies. FATCA also generally will impose a U.S. federal withholding tax of 30 percent on certain payments made to a non-financial foreign entity unless such entity provides the withholding agent a certification identifying certain direct and indirect U.S. owners of the entity or an exemption applies. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Under certain circumstances, a Non-U.S. Holder might be eligible for refunds or credits of such taxes. The Treasury Department recently released proposed regulations which, if finalized in their present form, would eliminate the federal withholding tax of 30 percent applicable to the gross proceeds of a sale or other disposition of Metacrine common stock. In its preamble to such proposed regulations, the U.S. Treasury Department stated that taxpayers may generally rely on the proposed regulations until final regulations are issued.
Holders of Metacrine common stock are encouraged to consult with their own tax advisors regarding the possible implications of FATCA on the disposition of Metacrine common stock pursuant to the Merger.
Information Reporting and Backup Withholding
Information reporting and backup withholding (at a current rate of 24 percent) may apply to the proceeds received by a holder pursuant to the Merger. Backup withholding generally will not apply to (1) a U.S. Holder that furnishes a correct taxpayer identification number and certifies that such U.S. Holder is not subject to backup withholding on IRS Form W-9 (or a substitute or successor form); or (2) a Non-U.S. Holder that (a) provides a certification of such Non-U.S. Holder’s non-U.S. status on the appropriate series of IRS Form W-8 (or a substitute or successor form); or (b) otherwise establishes an exemption from backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against the holder’s U.S. federal income tax liability, if the required information is timely furnished to the IRS.

If Metacrine proposes to register the offer and sale of its common stock under the Securities Act, in connection with the public offering of such common stockholders of registrable securities will be entitled to certain “piggyback” registration rights allowing them to include their shares in such registration, subject to certain marketing and other limitations. As a result, whenever Metacrine proposes to file a registration statement under the Securities Act, other than with respect to a demand registration or a registration statement on Forms S-4 or S-8, the holders registrable securities are entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include their shares in the registration.

The holders of certain shares of Metacrine's common stock are entitled to certain Form S-3 registration rights and may make a written request that Metacrine register the offer and sale of their shares on a registration statement on Form S-3 if Metacrine is eligible to file a registration statement on Form S-3 so long as the request covers securities the anticipated aggregate public offering price of which, after payment of underwriting discounts and commissions, is at least $1 million. These stockholders may make two requests for registration on Form S-3 in any 12-month period; however, Metacrine will not be required to effect a registration on Form S-3 during the period that is 30 days before Metacrine's good faith estimate of the date of filing of, and ending on a date that is 90 days after the effective date of, a Metacrine-initiated registration, provided, that Metacrine is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective. Additionally, if Metacrine determines that it would be seriously detrimental to its stockholders to effect such a registration, it has the right to defer such registration, not more than twice in any 12-month period, for a period of up to 60 days.

1.6 Directors of the Surviving Corporation . The Parties shall take all actions necessary so that the directors of Merger Sub immediately prior to the Effective Time shall, from and after the Effective Time, be the directors of the Surviving Corporation until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and the Bylaws.

ARTICLE II
EFFECT OF THE MERGER ON SECURITIES; EXCHANGE
2.1 Effect on Capital Stock.
(a) At the Effective Time, as a result of the Merger and without any action on the part of the holder of any capital stock of the Company, Parent or Merger Sub:
(i) Merger Consideration. Each Share issued and outstanding immediately prior to the Effective Time (other than Shares held in treasury, if any (each such Share, an “Excluded Share” and, collectively, “Excluded Shares”)) shall be automatically converted into the right to receive the Exchange Ratio (the aggregate shares of Parent Common Stock issued by applying the Exchange Ratio in accordance with this Section 2.1, the “Merger Consideration”).
(ii) At the Effective Time, all of the Shares (other than Excluded Shares) shall cease to be outstanding, shall be cancelled and shall cease to exist, and (A) each certificate (a “Certificate”) formerly representing any of the Shares (other than Excluded Shares) and (B) each book-entry account formerly representing any uncertificated Shares (“Uncertificated Shares”) (other than Excluded Shares) shall thereafter represent only the right to receive the Merger Consideration, any distributions or dividends payable pursuant to Section 2.2(c) and cash in lieu of any fractional shares of Parent Common Stock payable pursuant to Section 2.2(e), without interest, in each case to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.2, in the case of certificated Shares, and upon receipt by the Exchange Agent of an “agent’s message” in customary form in accordance with Section 2.2(i) in the case of Uncertificated Shares.
(iii) Cancellation of Excluded Shares. Each Excluded Share shall, by virtue of the Merger and without any action on the part of the Company, Parent, Acquisition Sub, Merger Sub or the holder thereof, cease to be outstanding, shall be cancelled without payment of any consideration therefor and shall cease to exist.

TABLE OF CONTENTS

(b) Merger Sub. Each share of common stock, par value $0.001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one validly issued, fully paid and nonassessable share of common stock, $0.001 par value per share, of the Surviving Corporation, and such converted shares shall constitute the only outstanding shares of capital stock of the Surviving Corporation.
2.2 Exchange of Certificates.
(a) Exchange Agent and Exchange Fund. Prior to the Effective Time, the Parties shall designate American Stock Transfer & Trust Company, LLC (“AST”) or if AST is unwilling or unable serve then such other mutually agreeable bank or trust company as the exchange agent in connection with the Merger (the “Exchange Agent”). The Exchange Agent shall also act as the agent for the Company’s stockholders for the purpose of receiving and holding their Certificates and Uncertificated Shares and shall obtain no rights or interests in the shares represented thereby. At the Closing, Parent shall issue and cause to be deposited with the Exchange Agent: (i) non-certificated shares of Parent Common Stock represented by book entry issuable pursuant to Section 2.1(a); and (ii) cash sufficient to make payments in lieu of fractional shares in accordance with Section 2.2(e). The shares of Parent Common Stock and cash amounts so deposited with the Exchange Agent, together with any dividends or distributions received by the Exchange Agent with respect to such shares of Parent Common Stock, are referred to collectively as the “Exchange Fund.”
(b) Exchange Procedures. Promptly after the Effective Time (and in any event within three (3) Business Days thereafter), the Exchange Agent shall mail to each holder of record of Shares represented by a Certificate (other than holders of Excluded Shares) or Uncertificated Shares (i) a letter of transmittal in customary form specifying that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 2.2(g)) or Uncertificated Shares to the Exchange Agent, such letter of transmittal to be in such form and have such other provisions as Parent and the Company may reasonably agree, and (ii) instructions for surrendering the Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 2.2(g)) or Uncertificated Shares (including instructions for sending an “agent’s message” in customary form (or such other evidence, if any, as the Exchange Agent may reasonably request)) to the Exchange Agent. Upon surrender of a Certificate (or affidavit of loss in lieu of the Certificate as provided in Section 2.2(g)) to the Exchange Agent in accordance with the terms of such letter of transmittal or with respect to Uncertificated Shares receipt of an “agent’s message” in customary form (or such other evidence, if any, as the Exchange Agent may reasonably request) by the Exchange Agent, the holder of such Certificate or Uncertificated Share shall be entitled to receive in exchange therefor non-certificated shares of Parent Common Stock in book-entry form, and cash in lieu of any fractional share of Parent Common Stock pursuant to Section 2.2(e) and any dividends or other distributions pursuant to Section 2.2(c), less any required Tax withholdings as provided in Section 2.2(h). The Certificate or Uncertificated Share so surrendered shall forthwith be cancelled. Until due surrender of the Certificates or Uncertificated Share, each Certificate and Uncertificated Share shall be deemed, from and after the Effective Time, to represent only the right to receive shares of Parent Common Stock (and cash in lieu of any fractional share of Parent Common Stock pursuant to Section 2.2(e)). In the event of a transfer of ownership of Shares that is not registered in the transfer records of the Company, the applicable portion of Merger Consideration to be exchanged upon due surrender of the Certificate or Uncertificated Share pursuant to Section 2.1(a) may be issued and paid to such transferee if the Certificate formerly representing such Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and the Person requesting such payment shall pay any transfer or other Taxes required by reason of the transfer or establish to the reasonable satisfaction of Parent that such Taxes have been paid or are not applicable.
(c) Distributions with Respect to Unexchanged Shares. All shares of Parent Common Stock to be issued pursuant to the Merger shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by Parent in respect of the Parent Common Stock, the record date for which is after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares of Parent Common Stock issuable in the Merger. No dividends or other distributions in respect of the Parent Common Stock issued pursuant to the Merger shall be paid to any holder of any unsurrendered Certificate of Uncertificated Share until such Certificate (or affidavit of loss in lieu thereof as provided in Section 2.2(g)) or Uncertificated Share is surrendered for exchange in accordance with this Article II.
A-3

TABLE OF CONTENTS

Subject to the effect of applicable Laws, following surrender of any such Certificate (or affidavit of loss in lieu thereof as provided in Section 2.2(g)) or Uncertificated Share, there shall be issued and/or paid to the holder of the whole shares of Parent Common Stock issued in exchange therefor, without interest thereon, (A) at the time of such surrender, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time, but with a payment date subsequent to surrender.
(d) Transfers. From and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the Shares that were outstanding immediately prior to the Effective Time.
(e) Fractional Shares. No certificate or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates or Uncertificated Shares, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Parent. The Exchange Agent, acting as agent for the holders of Shares otherwise entitled to receive fractional shares of Parent Common Stock, will aggregate all fractional shares of Parent Common Stock that would otherwise have been required to be distributed and cause them to be sold in the open market for the accounts of such holders. Notwithstanding any other provision of this Agreement, each holder of Shares who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock shall receive, in lieu thereof, cash, rounded to the nearest whole cent and without interest, in an amount equal to the proceeds from such sale by the Exchange Agent, if any, less any brokerage commissions or other fees, transfer Taxes or other out-of-pocket transaction costs, as well as any expenses of the Exchange Agent incurred from the sale of such fractional shares of Parent Common Stock in accordance with such holder’s fractional interest in the aggregate number of shares of Parent Common Stock sold.
(f) Termination of Exchange Fund. Any portion of the Exchange Fund (including the proceeds of any investments of the Exchange Fund) that remains unclaimed by the stockholders of the Company for one hundred eighty (180) days after the Effective Time shall be delivered, at Parent’s option, to Parent. Any holder of Shares (other than Excluded Shares) who has not theretofore complied with Section 2.2(b) shall thereafter look only to Parent for delivery of any shares of Parent Common Stock, payment of cash in lieu of fractional shares and any dividends and other distributions in respect of the Parent Common Stock to be issued or paid pursuant to the provisions of this Article II (after giving effect to any required Tax withholdings as provided in Section 2.2(h)) upon due surrender of its Certificates (or affidavits of loss in lieu of the Certificates as provided in Section 2.2(g)) or Uncertificated Share, without any interest thereon. Notwithstanding the foregoing, none of the Surviving Corporation, Parent, Exchange Agent or any other Person shall be liable to any former holder of Shares for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. To the fullest extent permitted by Law, immediately prior to the date any Merger Consideration would otherwise escheat to or become the property of any Governmental Entity, such Merger Consideration shall become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.
(g) Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed, and, if required by Parent or the Exchange Agent, the posting by such Person of a bond in such reasonable amount as Parent or the Exchange Agent, as applicable, may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the cash in lieu of fractional shares, shares of Parent Common Stock, and any dividends and other distributions in respect of the Parent Common Stock that would have been issuable or payable pursuant to the provisions of this Article II (after giving effect to any required Tax withholdings as provided in Section 2.2(h)) had such lost, stolen or destroyed Certificate been surrendered.
(h) Withholding Rights. Each of Parent, the Surviving Corporation and the Exchange Agent (each, a “Withholding Agent”) shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any other applicable state, local or foreign Tax Law. To the extent that amounts are so deducted or withheld by the applicable Withholding Agent, such deducted or withheld
A-4

TABLE OF CONTENTS

amounts (i) shall be remitted by such Withholding Agent to the applicable Governmental Entity and (ii) shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made by such Withholding Agent.
(i) Uncertificated Shares. Any holder of Uncertificated Shares shall not be required to deliver a Certificate or an executed letter of transmittal to the Exchange Agent to receive the Merger Consideration, any dividends or other distributions payable pursuant to Section 2.2(c) and cash in lieu of any fractional shares of Parent Common Stock payable pursuant to Section 2.2(e) that such holder is entitled to receive pursuant to this Article II in respect of such Uncertificated Shares. In lieu thereof, each registered holder of one or more Uncertificated Shares whose Shares were converted into the right to receive the Merger Consideration, any distributions or dividends payable pursuant to Section 2.2(c) and cash in lieu of any fractional shares of Parent Common Stock payable pursuant to Section 2.2(e), shall, upon receipt by the Exchange Agent of an “agent’s message” in customary form (or such other evidence, if any, as the Exchange Agent may reasonably request), be entitled to receive, and the Surviving Corporation shall cause the Exchange Agent to pay and deliver as soon as reasonably practicable after the Effective Time, the Merger Consideration, any dividends or other distributions payable pursuant to Section 2.2(c) and cash in lieu of any fractional shares of Parent Common Stock payable pursuant to Section 2.2(e) for each Uncertificated Share, and the Uncertificated Shares of such holder shall forthwith be cancelled. No interest will be paid or accrued on any amount payable to a holder of Uncertificated Shares.
2.3 Adjustments to Prevent Dilution. In the event that the Company changes the number of Shares or securities convertible or exchangeable into or exercisable for any such Shares, or Parent changes the number of shares of Parent Common Stock or securities convertible or exchangeable into or exercisable for any such Parent Common Stock, in each case issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, reorganization, subdivision, or other similar transaction, the Merger Consideration shall be equitably adjusted to eliminate the effects of such event on the Merger Consideration.
2.4 Treatment of Equity Awards, ESPP and Warrants.
(a) At the Effective Time, each Company Option held by a continuing employee or service provider that is outstanding and unexercised immediately prior to the Effective Time (other than a Company Option covered by Section 2.4(b)) shall, without any action on the part of Parent, the Company or the holder thereof, cease to represent a right to acquire Shares and shall be substituted and converted automatically into a Parent option award to purchase the number of shares of Parent Common Stock (each, an “Adjusted Option”) equal to the product obtained by multiplying (i) the number of Shares subject to the Company Option immediately prior to the Effective Time, by (ii) the Exchange Ratio, with any fractional shares rounded down to the nearest whole share.

Parent shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery with respect to the Company Equity Awards assumed by it in accordance with this Section 2.4.

corresponding Company Warrant immediately prior to the Effective Time, divided by (y) the Exchange Ratio, rounded up to the nearest whole cent. Each Adjusted Warrant shall otherwise be subject to the same terms and conditions applicable to the corresponding Company Warrant.
2.5 Calculation of Company Net Cash.
(a) For purposes of this Agreement, the “Anticipated Closing Date” shall be the anticipated date for Closing, as agreed upon by Parent and the Company at least 10 days prior to the later of (i) the Company Stockholders Meeting and (ii) the Parent Stockholders Meeting, in each case subject to adjournment or postponement pursuant to Section 5.5. At least five days prior to the Anticipated Closing Date, the Company shall deliver to Parent a schedule (the “Net Cash Schedule”) setting forth, in reasonable detail, the Company’s good faith, estimated calculation of the Company Net Cash (the “Net Cash Calculation”) as of the Anticipated Closing Date, prepared and certified by the Company’s Chief Financial Officer (or if there is no Chief Financial Officer, the principal accounting officer). The Company shall make available to Parent, or its accountants and/or counsel, the work papers and back-up materials used or useful in preparing the Net Cash Schedule, as reasonably requested by Parent.
(b) Within three days after delivery of the Net Cash Schedule (the “Response Date”), Parent will have the right to dispute any part of the Net Cash Schedule by delivering a written notice to that effect to the Company (a “Dispute Notice”). Any Dispute Notice shall identify in reasonable detail the nature of any proposed revisions to the Net Cash Calculation.
(c) If on or prior to the Response Date, Parent (i) notifies the Company in writing that it has no objections to the Net Cash Calculation or (ii) fails to deliver a Dispute Notice as provided in Section 2.5(a), then the Net Cash Calculation as set forth in the Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent Company Net Cash at the Anticipated Closing Date for purposes of this Agreement.
(d) If Parent delivers a Dispute Notice on or prior to the Response Date, then Representatives of both parties shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Company Net Cash, which agreed upon Company Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Company Net Cash, at the Anticipated Closing Date for purposes of this Agreement.
(e) If Representatives of Parent and the Company are unable to negotiate an agreed-upon determination of Company Net Cash at the Anticipated Closing Date pursuant to Section 2.5(d) within three days after delivery of the Dispute Notice (or such other period as Parent and the Company may mutually agree upon), then Parent and the Company shall jointly select an independent auditor of recognized national standing (the “Accounting Firm”) to resolve any remaining disagreements as to the Net Cash Calculation. The Company shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the Net Cash Schedule, and Parent and the Company shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within 10 days after accepting its selection. The Company and Parent shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided, that no such presentation or discussion shall occur without the presence of a Representative of each of the Company and Parent. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Company Net Cash, made by the Accounting Firm shall be deemed to have been finally determined for purposes of this Agreement and to represent Company Net Cash at the Anticipated Closing Date for purposes of this Agreement, and the parties shall delay the Closing until the resolution of the matters described in this Section 2.5(d). The fees and expenses of the Accounting Firm shall be allocated between Parent and Company in the same proportion that the disputed amount of Company Net Cash that was unsuccessfully disputed by such party (as finally determined by the Accounting Firm) bears to the total disputed amount of Company Net Cash, (and for the avoidance of doubt the fees and expenses to be paid by the Company shall reduce Company Net Cash). If this Section 2.5(d) applies as to the determination of Company Net Cash at the Anticipated Closing Date, upon resolution of the matter in
A-7

TABLE OF CONTENTS

accordance with this Section 2.5(d), the parties shall not be required to determine Company Net Cash again, even if the Closing Date occurs later than the Anticipated Closing Date, except that either party may request a re-determination of Company Net Cash if the Closing Date is more than five business days after the Anticipated Closing Date.
2.6 No Dissenter’s Rights. In accordance with Section 262 of the DGCL, no appraisal rights shall be available to holders of Shares in connection with the Merger or any other transaction contemplated by this Agreement.

To the extent that amounts are so withheld and timely remitted by the Parent, the Merger Sub, the Company, the Surviving Corporation or the Exchange Agent, as the case may be, to the applicable Governmental Entity, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder or other recipient in respect of which such deduction and withholding was made.

(d) The obligations set forth in this Section 5.11 may not be terminated, amended or otherwise modified in any manner that adversely affects any Indemnified Person (or any other person (and his or her heirs and representatives) who is a beneficiary pursuant to the Tail Policy) without the prior written consent of such affected Indemnified Person or other person. Each of the Indemnified Persons or other persons (and his or her heirs and representatives) who are beneficiaries pursuant to the Tail Policy are intended to be third party beneficiaries of this Section 5.11, with full rights of enforcement. The rights of the Indemnified Persons (and other persons (and his or her heirs and representatives) who are beneficiaries pursuant to the Tail Policy) pursuant to this Section 5.11 will be in addition to, and not in substitution for, any other rights that such persons may have pursuant to (i) the Company Charter and Company Bylaws; (ii) the similar organizational documents of the Subsidiaries of the Company; (iii) any and all indemnification agreements entered into with the Company or any of its Subsidiaries; or (iv) applicable Law.
(e) In the event Parent or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, Parent shall ensure that the successors and assigns of Parent or the Surviving Corporation, as the case may be, or at Parent’s option, Parent, shall assume the obligations set forth in this Section 5.11.

NOW, THEREFORE, in consideration of the covenants, promises and representations set forth herein and in the Merger Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

Second Acquisition Sub is duly qualified or licensed to do business in each jurisdiction where the nature of its business or the ownership or leasing of its properties make such qualification necessary, other than in such jurisdictions where the failure to be so qualified or licensed, individually or in the aggregate, has not had and would not reasonably be expected to have a Parent Material Adverse Effect. Parent has delivered or made available to the Company prior to execution of this Amendment No. 1, true and complete copies of the certificate of incorporation of Second Acquisition Sub.
2.2 Corporate Authority and Approval. Second Acquisition Sub has all requisite corporate power and authority to execute and deliver this Amendment No. 1.

Dear Members of the Board of Directors:
We understand that Equillium, Inc. (“Equillium” or the “Company”) has entered into that certain Agreement and Plan of Merger, dated as of September 6, 2022, (the “Merger Agreement”) in connection with a potential business combination transaction (the “Transaction”) by and among Equillium, Equillium Acquisition Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Parent, Triumph Merger Sub, Inc., a Delaware corporation and indirect wholly-owned subsidiary of Parent (“Merger Sub”), and Metacrine, Inc., a Delaware corporation (“MTCR” or the “Target”) and other agreements to be executed in connection therewith (together with the Merger Agreement (as defined below), the “Transaction Documents”), the acquisition by Parent of the Target through the merger of Merger Sub with and into the Target (the “Merger”), with the Target continuing as the surviving entity of the Merger and as an indirect wholly-owned subsidiary of Parent. At the effective time of the Merger (the “Effective Time”), by virtue of the Merger and without any further action on the part of Parent, Merger Sub, the Target or any stockholder of the Target, among other things, each share of common stock, par value $0.0001 of the Target (the “Shares”), issued and outstanding immediately prior to the Effective Time (other than Shares held in treasury) will, by virtue of the Merger Agreement (and subject to the terms and conditions thereof) and without any action on the part of the holder thereof, be converted into and thereafter represent the right to receive a number of shares of the common stock, par value $0.0001 per share, of Parent (the “Parent Common Stock”), equal to the Exchange Ratio, without interest, and (ii) cash in lieu of any fractional shares of Parent Common Stock (collectively, the “Merger Consideration”). “Upfront Merger Consideration” means the amount equal to (i) Company Net Cash (as defined in the Merger Agreement) multiplied by (ii) 1.25. “Exchange Ratio” means (x) the Upfront Merger Consideration divided by the price per share of the Parent’s common stock determined based on the 10 day trading volume weighted average price per share of Parent’s common stock calculated 10 trading days prior to the Effective Time subject to the maximum and minimum price per share of $4.50 and $2.70, respectively, and the other adjustments set forth in the Merger Agreement.
The Company has supplied us with a description of the Transaction and copies of relevant Transaction Documents.
The Board of Directors of the Company (“you” or the “Board of Directors”) has asked us to render an opinion (the “Opinion”) as to the fairness of the Transaction to the common stockholders of the Company from a financial point of view. We do not express any views on any other terms of the Transaction and our Opinion does not address the Company’s underlying business decision to effect the transaction. We have not been asked to, and did not, solicit third-party expressions of interest in acquiring all or any part of the Company’s assets or securities. Additionally, we have not been asked to negotiate the Transaction or advise you with respect to alternative business strategies that might exist for the Company.
1)
In the course of our analyses for rendering this Opinion, we have made such reviews, analyses, and inquiries as we have deemed necessary and appropriate under the circumstances, including, without limitation;
2)

We have not assumed any responsibility for independent verification of such information or assurances.
In arriving at our Opinion, we have not performed any independent appraisal of the assets of the Company. Our analysis does not constitute an examination, review of, or compilation of prospective financial statements in accordance with standards established by the American Institute of Certified Public Accountants (“AICPA”). We do not express an opinion or any other form of assurance on the reasonableness of the underlying assumptions or whether any of the prospective financial statements, if used, are presented in conformity with AICPA presentation guidelines. Further, there will usually be differences between prospective and actual results because events and circumstances frequently do not occur as expected and those differences may be material. We have also assumed the Company is not currently involved in any material transaction other than the Transaction, and those activities undertaken in the ordinary course of conducting its business.
Our Opinion is predicated on all transaction documents listed in this letter being executed with no material changes from the most recent drafts supplied to, and reviewed by, Vantage Point Advisors, Inc. (“Vantage Point”).
This Opinion is furnished solely for your benefit and does not constitute a recommendation to any member of the Board of Directors, any equity holder of the Company or any other person as to how such equity holder should vote or act with respect to the Transaction. This Opinion is delivered to each recipient subject to the conditions, scope of engagement, limitations and understanding set forth in this Opinion and subject to the understanding that the obligations of Vantage Point in the Transaction are solely corporate obligations. Furthermore, no officer, director, employee or shareholder of Vantage Point shall be subjected to any personal liability whatsoever to any person, nor will any such claim be asserted by or on behalf of you or your affiliates.
On the basis of the forgoing, it is our opinion that the Transaction is fair, from a financial point of view, to the common stockholders of the Company.
Very truly yours,

Board of Directors of
Metacrine, Inc. (in its capacity as such)
4225 Executive Square, Suite 600
San Diego, CA 92037
Members of the Board of Directors:
We understand that Metacrine, Inc., a Delaware corporation (the “Company”), proposes to enter into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Equillium, Inc., a Delaware corporation (“Parent”), Equillium Acquisition Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Parent (“Acquisition Sub”), and Triumph Merger Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Acquisition Sub (“Merger Sub”), which will provide for, among other things, the merger of Merger Sub with and into the Company (the “Merger”) with the Company continuing as the surviving entity in the Merger as a wholly-owned subsidiary of Acquisition Sub. As a result of the Merger, (a) each outstanding share of common stock of the Company, par value $0.0001 per share (the “Company Common Stock”), other than Excluded Shares, shall be converted solely into the right to receive a number of shares of Parent’s common stock, par value $0.0001 per share (“Parent Common Stock”), equal to the Exchange Ratio, together with any cash payments made in lieu of fractional shares, and (b) each Company Option, each Company Warrant, and each Company RSU (as such terms are defined in the Merger Agreement) shall, upon conversion, be converted into an Adjusted Option, Adjusted Warrant, or an Adjusted Parent RSU (as such terms are defined in the Merger Agreement), as the case may be, providing for the purchase or covering the number of shares of Parent Common Stock based upon the Exchange Ratio. As used herein, (1) the “Exchange Ratio” is equal to the quotient of (I) company net cash (as defined in and determined pursuant to the terms of the Merger Agreement) multiplied by 1.25, and (II) the price per share of the Parent Common Stock determined based on the 10-day trading volume weighted average price per share of the Parent Common Stock calculated 10 trading days prior to the Closing Date (provided that such value shall not be greater than $4.50 per share of Parent Common Stock or less than $2.70 per share of Parent Common Stock), and (B) the Aggregate Fully Diluted Shares; and (2) “Excluded Shares” means shares of Company Common Stock that are held in treasury of the Company immediately prior to the Effective Time and Dissenting Shares (as defined in the Merger Agreement). The terms and conditions of the Merger are more fully set forth in the Merger Agreement and capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Merger Agreement.
The Board of Directors of the Company (in its capacity as such) has requested our opinion, as investment bankers, as to the fairness, from a financial point of view and as of the date hereof, of the Exchange Ratio to the holders of the Company Common Stock (other than the Excluded Shares) (the “Opinion”). At your direction, we have assumed that as of the anticipated closing date, the company net cash will be $25.3 million.
In the course of performing our review and analyses for rendering our Opinion, we have:
i.
reviewed the financial terms of a draft copy of the Merger Agreement, dated as of August 31, 2022, such draft being the latest draft provided to us (the “Draft Merger Agreement”);
ii.
reviewed the audited consolidated financial statements of the Company contained in its Annual Reports on Form 10-K for the fiscal years ended December 31, 2021 and December 31, 2020, and unaudited consolidated financial statements of the Company contained in its Quarterly Report on Form 10-Q for the quarters ended March 31, 2022 and June 30, 2022;
iii.
reviewed the audited consolidated financial statements of Parent contained in its Annual Reports on Form 10-K for the fiscal years ended December 31, 2021 and December 31, 2020, and unaudited consolidated financial statements of Parent contained in its Quarterly Report on Form 10-Q for the quarters ended March 31, 2022 and June 30, 2022;

iv.
reviewed certain publicly available analyses and forecasts relating to the Company and Parent prepared by equity analysts who report on the Company and Parent;
v.
reviewed certain internal financial analyses and forecasts of the Company prepared by and provided to us by the management of the Company relating to the Company’s business (the “Company Projections”), and utilized per instruction of the Company;
vi.
reviewed certain internal financial analyses and forecasts of Parent prepared by the management of Parent and adjusted and provided by the management of the Company relating to Parent’s business (the “Parent Projections”, and together with the Company Projections, the “Projections”), and utilized per instruction of the Company;
vii.
conducted discussions with members of senior management and representatives of the Parent with respect to the Parent Projections;
viii.
compared the trading and valuation metrics of the Parent with publicly available information concerning other publicly-traded companies, in each case, that we deemed relevant;
ix.
reviewed the current and historical market prices of the Company Common Stock and Parent Common Stock, respectively, and certain publicly traded securities of such other companies, in each case, that we deemed relevant;
x.
performed a liquidation analysis of the Company based upon information provided to us by management of the Company;
xi.
reviewed and analyzed, based on the Parent Projections, the projected cash flows to be generated by Parent to determine Parent’s discounted cash flows; and
xii.
performed such other financial studies, analyses and investigations, and considered such other information, as we deemed appropriate for the purposes of the opinion.
In arriving at our Opinion, we have assumed and relied upon, without assuming liability or responsibility for independent verification, the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information that was publicly available or was provided to, discussed with or reviewed by us and upon the assurances of the management of the Company that they are not aware of any material relevant developments or matters related to the Company or Parent, respectively, or that may affect the Merger that have been omitted or that remain undisclosed to us. The Opinion does not address any legal, regulatory, tax, accounting or financial reporting matters, as to which we understand that the Company has obtained such advice as it deemed necessary from other advisors, and we have relied, with your consent, on such assessments made by such other advisors to the Company with respect to such matters. We have not conducted any independent verification of the Projections. Without limiting the generality of the foregoing, with respect to the Projections, we have assumed, with your consent, and based upon discussions with the management of the Company, that they have been reasonably prepared (or in the case of the Parent Projections, adjusted) by the management of the Company in good faith, and that the Projections reflect the best currently available estimates and judgments of the management of the Company of the future results of operations and financial performance of the Company and Parent. The Projections are based on numerous variables and assumptions that are inherently uncertain, including, without limitation, factors related to general economic and competitive conditions and, in particular, assumptions regarding increased market volatility and the widespread disruption, extraordinary uncertainty and unusual volatility arising from the effects of the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. Accordingly, actual results could vary significantly from those set forth in the Projections. We express no view as to the Projections or the assumptions on which they are based and we assume no responsibility for the accuracy or completeness thereof.
In arriving at our Opinion, we have not made any independent evaluations or appraisals of the assets or liabilities of the Company or Parent or any of their respective subsidiaries, and we have not been furnished with any such evaluations or appraisals, nor have we evaluated the solvency of the Company, Parent or any other entity under any state or federal law relating to bankruptcy, insolvency or similar matters. We have assumed that there has been no material change in the assets, financial condition, business or prospects of the Company or Parent since the date of the most recent relevant financial information made available to us. Without limiting the generality of the foregoing, we have undertaken no independent analysis of any pending or threatened litigation, regulatory

action, possible unasserted claims or other contingent liabilities to which the Company, Parent or any of their respective affiliates is a party or may be subject, and, at your direction and with your consent, our Opinion makes no assumption concerning, and therefore does not consider, the possible assertion of claims, outcomes or damages arising out of any such matters. We have also assumed that neither the Company, Parent, Acquisition Sub or Merger Sub is a party to any material pending transaction that has not been disclosed to us, including, without limitation, any financing, recapitalization, acquisition or merger, divestiture or spin-off, other than the Merger.
We have assumed that the representations and warranties of each party contained in the Merger Agreement and in all other related documents and instruments that are referred to therein are and will be true and correct as of the date or the dates made or deemed made, that each party thereto will fully and timely perform all of the covenants and agreements required to be performed by it under the Merger Agreement and any other agreement contemplated thereby, and that the transactions contemplated by the Merger Agreement, including, without limitation, the Merger, will be consummated in accordance with the terms of the Merger Agreement without waiver, modification or amendment of any term, condition or agreement. We have assumed that the final form of the Merger Agreement will be identical to the Draft Merger Agreement in all material respects. We have, with your consent, further assumed that any adjustment to the Merger Consideration pursuant to the terms of the Merger Agreement will not result in any adjustment to the Merger Consideration that is material to our analysis. We have also assumed that any governmental, regulatory and other consents and approvals contemplated in connection with the Merger will be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions will be imposed or waivers made that would have an adverse effect on the Company, Parent, Acquisition Sub, Merger Sub or the contemplated benefits of the Merger.
Our Opinion is necessarily based on economic, market, financial and other conditions as they exist, and on the information made available to us, as of the date of this letter. We have not considered any potential legislative or regulatory changes currently being considered by the United States Congress, the Securities and Exchange Commission (the “SEC”), or any other governmental or regulatory bodies, or any changes in accounting methods or generally accepted accounting principles that may be adopted by the SEC or the Financial Accounting Standards Board. It should be understood that, although subsequent developments may affect the conclusion reached in our Opinion, we do not have any obligation to update, revise or reaffirm the Opinion. Our Opinion addresses solely the fairness, from a financial point of view and as of the date hereof, of the Exchange Ratio to the holders of Company Common Stock (other than the Excluded Shares), and does not address any other terms in the Merger Agreement, or any other agreement contemplated by the Merger Agreement or relating to the Merger or any other aspect or implication of the Merger, including, without limitation, the form or structure of the Merger, or the fairness of the Merger or the Exchange Ratio to any other securityholders or creditors or any other constituency of the Company, including holders of Company Options, Company Warrants and Company RSUs and participations in the ESPP. Our Opinion does not address the Company’s underlying business decision to proceed with the Merger or the relative merits of the Merger compared to other alternatives available to the Company. We express no opinion as to the prices or ranges of prices at which shares of securities of any person, including shares of the Company Common Stock or the Parent Common Stock, will trade at any time, including following the announcement or consummation of the Merger. We have not been requested to opine as to, and our Opinion does not in any manner address, the amount or nature of compensation to any of the officers, directors or employees of any party to the Merger, or any class of such persons, relative to the compensation to be paid to the holders of Company Common Stock in connection with the Merger or with respect to the fairness of any such compensation.
This letter and the our Opinion is provided to the Board of Directors of the Company (in its capacity as such) for its information in connection with its consideration of the Merger and may not be used for any other purpose or disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever without our prior written consent, except that a copy of this letter may be included in its entirety in any filing the Company or Parent is required to make with the SEC in connection with the Merger if such inclusion is required by applicable law. Our Opinion does not constitute a recommendation to the Board of Directors or any stakeholder or stockholder of the Company or Parent as to how to vote or take any other action in connection with the Merger, including, without limitation, whether or not any holder of Company Common Stock should enter into any voting, stockholders’ or affiliates’ agreement with respect to the Merger.

As part of our investment banking services, we are regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, and for other purposes. We have acted as the Company’s financial advisor in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon consummation of the Merger (the “Advisory Fee”). In addition, the Company has agreed to reimburse our expenses and indemnify us for certain liabilities that may arise out of our engagement. We will also receive an additional fee for rendering the Opinion which is not contingent upon consummation of the Merger, but which is creditable against any Advisory Fee. We or our affiliates may also seek to provide financial, advisory and other investment banking services to the Company and Parent and/or certain of their respective affiliates in the future and would expect to receive fees for the rendering of any such services. Other than in connection with the Merger, we have not provided investment banking or financial advisory services to the Company, Parent or their respective affiliates and have not received compensation for any such services in the two years prior to the date of this Opinion. In the ordinary course of business, we and our clients may transact in the equity and debt securities of each of the Company and Parent and may at any time hold a long or short position in such securities.

Members of the Board of Directors:
We understand that Metacrine, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger dated September 6, 2022 (the “Merger Agreement”), by and among the Company, Equillium, Inc., a Delaware corporation (“Parent”), Equillium Acquisition Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Parent (“Acquisition Sub”), and Triumph Merger Sub, Inc., a Delaware corporation and a direct wholly-owned subsidiary of Acquisition Sub (“Merger Sub”), which provides for, among other things, the merger of Merger Sub with and into the Company (the “Merger”) with the Company continuing as the surviving entity in the Merger as a wholly-owned subsidiary of Acquisition Sub. As a result of the Merger, (a) each outstanding share of common stock of the Company, par value $0.0001 per share (the “Company Common Stock”), other than Excluded Shares, shall be converted solely into the right to receive a number of shares of Parent’s common stock, par value $0.0001 per share (“Parent Common Stock”), equal to the Exchange Ratio, together with any cash payments made in lieu of fractional shares, and (b) each Company Option, each Company Warrant, and each Company RSU (as such terms are defined in the Merger Agreement) shall, upon conversion, be converted into an Adjusted Option, Adjusted Warrant, or an Adjusted Parent RSU (as such terms are defined in the Merger Agreement), as the case may be, providing for the purchase or covering the number of shares of Parent Common Stock based upon the Exchange Ratio. As used herein, (1) the “Exchange Ratio” is equal to the quotient of (I) company net cash (as defined in and determined pursuant to the terms of the Merger Agreement) multiplied by 1.25, and (II) the price per share of the Parent Common Stock determined based on the 10-day trading volume weighted average price per share of the Parent Common Stock calculated 10 trading days prior to the Closing Date (provided that such value shall not be greater than $4.50 per share of Parent Common Stock or less than $2.70 per share of Parent Common Stock), and (B) the Aggregate Fully Diluted Shares; and (2) “Excluded Shares” means shares of Company Common Stock that are held in treasury of the Company immediately prior to the Effective Time and Dissenting Shares (as defined in the Merger Agreement). The terms and conditions of the Merger are more fully set forth in the Merger Agreement and capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Merger Agreement.
On September 2, 2022, we delivered our opinion, as investment bankers, to the Board of Directors of the Company (in its capacity as such, the “Board”), that as of that date, subject to the various assumptions made, procedures followed, matters considered and qualifications and limitations set forth in the MTS Opinion, the Exchange Ratio was fair, from a financial point of view, to the holders of the Company’s Common Stock (other than the Excluded Shares). Subsequent to our delivery of that opinion, circumstances have changed, as a result of which the Board has requested that we deliver a second opinion as to the fairness, as of the data here of, of the Exchange Ratio to the holders of the Company Common Stock (other than the Excluded Shares) (the “Opinion”).
In this analysis, at your direction, we have assumed that as of the anticipated closing date, the Company Net Cash will be $27.0 million.
In the course of performing our review and analyses for rendering our Opinion, we have:
i.
reviewed the financial terms of the Merger Agreement;
