SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The Company will provide the holders (the “Public Stockholders”) of the Company’s Public Shares per share, sold in the Initial Public Offering (the “Public Shares”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, subject to applicable law and stock exchange listing requirements. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per- share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 6). These Public Shares were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” The Company will proceed with a Business Combination only if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. If a stockholder vote is not required by applicable law or stock exchange listing requirements and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its Second Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the SEC and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with a Business Combination, the initial stockholders (as defined below) have agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination or don’t vote at all. In addition, the initial stockholders have agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Certificate of Incorporation will provide that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company.

The Sponsor and the Company’s officers and directors (the “initial stockholders”) will agree not to propose an amendment to the Certificate of Incorporation to modify the substance or timing of the Company’s obligation to allow redemptions in connection with its initial Business Combination or redeem 100% of the Public Shares if the Company does not complete a Business Combination within the initial Combination Period (as defined below) or with respect to any other provisions relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or October 23, 2022 (as such period may be extended by the Company’s stockholders in accordance with the Certificate of Incorporation, the “Combination Period”), the Company will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than 10 business days thereafter, redeem 100% of the Public Shares, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (net of taxes payable and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The initial stockholders agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial stockholders acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00 or potentially less. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) not will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses and other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Affiliates of the Company’s Co-Chairs (the “forward purchasers”) have entered into forward purchase agreements with our Company which provide for the purchase by the forward purchasers of shares of Class A common stock in an aggregate share amount equal to 5,000,000 shares of Class A common stock, plus an aggregate of 1,666,667 warrants exercisable to purchase one share of Class A common stock at $11.50 per share, subject to adjustment, for an aggregate purchase price of $50,000,000, or $10.00 for one share of Class A common stock and one-third of one warrant, in a private placement to occur concurrently with the closing of the initial business combination. The warrants to be issued as part of the forward purchase agreements will be identical to the warrants sold as part of the units in the initial public offering. The obligations under the forward purchase agreements do not depend on whether any shares of Class A common stock are redeemed by the Company’s public stockholders.

Proposed Business Combination

On March 17, 2021, the Company entered into the Merger Agreement by and among Supernova, Orchids Merger Sub, Inc., a Delaware corporation and a newly formed direct, wholly owned subsidiary of Supernova (“First Merger Sub”), Orchids Merger Sub, LLC, a Delaware limited liability company and direct, wholly owned subsidiary of Supernova (“Second Merger Sub”), and OfferPad, Inc., a Delaware corporation (“Offerpad”).

Pursuant to the Merger Agreement, the parties will enter into a business combination transaction (the “Business Combination”) by which (i) First Merger Sub will merge with and into Offerpad, with Offerpad being the surviving entity in the merger (the “First Merger”), and (ii) Offerpad will merge with and into Second Merger Sub, with Second Merger Sub being the surviving entity in the merger (the “Second Merger” and, together with the First Merger, the “Mergers” and, together with the other transactions contemplated by the Merger Agreement, the “Transactions” and the closing of the Transactions, the “Closing”). In connection with the Closing, Supernova will change its name to “Offerpad Solutions, Inc.”

The value of the aggregate equity consideration to be paid to Offerpad’s stockholders and optionholders in the Transactions will be equal to $2,250,000,000 (the “Equity Value”). At the Closing, each share of common stock and preferred stock of Offerpad that is issued and outstanding immediately prior to the effective time of the First Merger (other than “Excluded Shares”, as defined in the Merger Agreement) will be cancelled and converted into the right to receive a number of shares of Supernova common stock equal to an exchange ratio determined by dividing the Equity Value by the “Aggregate Fully Diluted Company Common Stock” (as defined in the Merger Agreement).

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

At the Closing, each option to purchase Offerpad common stock, whether vested or unvested, will be assumed and converted into an option to purchase a number of shares of Supernova Class A common stock in the manner set forth in the Merger Agreement.

Concurrently with the execution of the Merger Agreement, certain investors (the “PIPE Investors”) entered into subscription agreements (the “PIPE Subscription Agreements”) pursuant to which the PIPE Investors have committed to purchase in a private placement 20,000,000 shares of Supernova Class A common stock (the “PIPE Shares”) at a purchase price of $10.00 per share and an aggregate purchase price of $200,000,000 (the “PIPE Investment”). The purchase of the PIPE Shares is conditioned upon, among other things, the consummation of the Transactions and will be consummated concurrently with the Closing. The shares of Class A common stock to be issued pursuant to the PIPE Subscription Agreements have not been registered under the Securities Act and will be issued in reliance on the availability of an exemption from such registration.

In connection with the execution of the Merger Agreement, the Company entered into a sponsor support agreement (the “Sponsor Support Agreement”) with the Sponsor, Offerpad and the Company’s directors and officers. Pursuant to the Sponsor Support Agreement, the Sponsor and the Company’s directors and officers have, among other things, agreed to vote all of their shares of the Company’s capital stock in favor of the approval of the Transactions. In addition, the Sponsor has agreed that 20% of its shares of Class B common stock issued in connection with the initial public offering (the “Sponsor Shares”) will be unvested and subject to forfeiture as of the Closing and will only vest if, during the five year period following the Closing, (i) the volume weighted average price of the Company’s Class A common stock equals or exceeds $12.00 for any twenty trading days within a period of thirty consecutive trading days or (ii) there is a change of control of Supernova. Any Sponsor Shares that remain unvested after the fifth anniversary of the Closing will be forfeited. The Sponsor Support Agreement will terminate upon the termination of the Merger Agreement if the Closing does not occur.

The proposed Business Combination is expected to be consummated after receipt of the required approvals by the stockholders of the Company and Offerpad and the satisfaction or waiver of certain other customary conditions. For full details and the filed agreements, refer to our Current Report on 8-K announcing the Merger Agreement filed on March 18, 2021.

Liquidity and Going Concern

As of March 31, 2021, the Company had approximately $0.8 million in its operating bank accounts and a working capital deficit of approximately $2.1 million (not taking into account approximately $67,000 of taxes that may be paid using investment income from the Trust Account). The Company has incurred and expects to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. There is no assurance that the Company’s plans to consummate a Business Combination or raise additional funds will be successful within the Combination Period. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that the specific impact is not readily determinable as of the date of the unaudited condensed financial statements. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 2—Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the unaudited condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the period presented. Operating results for the three months ended March 31, 2021 are not necessarily indicative of the results that may be expected through December 31, 2021.

The accompanying unaudited condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Form 10-K/A filed by the Company with the SEC on May 25, 2021.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard.

Use of Estimates

The preparation of unaudited condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of March 31, 2021 and December 31, 2020.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which, at times, may exceed the Federal depository insurance coverage of $250,000, and investments held in Trust Account. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. The Company’s investments held in the Trust Account as of March 31, 2021 are comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in a money market funds that comprise only U.S. treasury securities money market funds.

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Investments Held in the Trust Account

The Company’s portfolio of investments is comprised solely of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities, or a combination thereof. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the condensed balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in net gain on investments held in Trust Account in the accompanying unaudited condensed statement of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

As of March 31, 2021 and December 31, 2020, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, income tax payable and franchise tax payable approximate their fair values due to the short-term nature of the instruments. The Company’s portfolio of investments held in the Trust Account is comprised of investments in U.S. Treasury securities with an original maturity of 185 days or less or investments in money market funds that invest in U.S. government securities, or a combination thereof. The fair value for trading securities is determined using quoted market prices in active markets. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants.

Offering Costs Associated with the Initial Public Offering

The Company complies with the requirements of the ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A – “Expenses of Offering.” Offering costs consist of legal, accounting, underwriting fees and other costs directly related to the Initial Public Offering

The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. In accordance with ASC 825-10 “Financial Instruments”, offering costs attributable to the issuance of the derivative liabilities have been allocated based on their relative fair value of total proceeds and are recognized in the unaudited condensed statement of operations as incurred. Offering costs associated with the Public Shares were charged to stockholders’ equity upon the completion of the Initial Public Offering.

Class A Common Stock Subject to Possible Redemption

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption (if any) is classified as a liability instrument and measured at fair value. Conditionally redeemable common stock (including common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) is classified as temporary equity. At all other times, common stock is classified as stockholders’ equity. The Company’s common stock features certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of March 31, 2021 and December 31, 2020, 34,004,650 and 33,488,198 shares of common stock subject to possible redemption are presented as temporary equity, outside of the stockholders’ equity section of the Company’s condensed balance sheets, respectively.

Net Income (Loss) Per Common Share

Net income (loss) per common share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period. The Company has not considered the effect of the warrants sold in the Initial Public Offering and private placement to purchase an aggregate of 20,116,667 shares in the calculation of diluted income (loss) per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive.

The Company’s unaudited condensed statement of operations includes a presentation of income (loss) per common share for Class A common stock subject to possible redemption in a manner similar to the two-class method of income (loss) per common share. Net income (loss) per common share, basic and diluted, for Class A common stock subject to possible redemption is calculated by dividing the proportionate share of income or loss on marketable securities held by the Trust Account, net of applicable franchise and income taxes, by the weighted average number of shares of Class A common stock subject to possible redemption outstanding since original issuance.

11

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

Net income (loss) per common share, basic and diluted, for non-redeemable common stock is calculated by dividing the net income (loss), adjusted for income or loss on marketable securities attributable to common stock subject to possible redemption, by the weighted average number of non-redeemable common stock outstanding for the period.

Non-redeemable common stock includes Founder Shares and non-redeemable shares of Class A common stock as these shares do not have any redemption features. Non-redeemable common stock participates in the income or loss on marketable securities based on non-redeemable shares’ proportionate interest.

The following table reflects the calculation of basic and diluted net income (loss) per common share:

Derivative Liabilities

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The 13,416,667 issued in connection with the Initial Public Offering (the “Public Warrants”) and the 6,700,000 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s unaudited condensed statement of operations. The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation model and subsequently, the fair value of the Private Placement Warrants have been estimated using a Monte Carlo simulation model each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants.

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

In connection with the closing of our initial public offering, the Company entered into forward purchase agreements to which its Sponsors committed to purchase the Company’s Class A common stock in an aggregate amount equal to 5,000,000 shares of our common stock, plus an aggregate of 1,666,667 warrants to purchase one share of Class A common stock at $11.50 per share, for an aggregate purchase price of $50,000,000, or $10.00 for one share of Class A common stock and one-third of one warrant, in a private placement that is conditioned upon, and will be consummated concurrently with, the Closing. The forward purchase agreements are recognized as derivative liabilities in accordance with ASC 815-40. Accordingly, the Company recognizes the forward purchase agreements as liabilities at fair value and adjusts the instrument to fair value at each reporting period. The fair value of the forward purchase agreements is determined as the estimated unit value less the net present value of the forward purchase agreements.

Income Taxes

The Company uses the asset and liability method of accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities at currently enacted tax rates. These temporary differences primarily relate to net operating loss carryforwards available to offset future taxable income. Valuation allowances are established, if necessary, to reduce a deferred tax asset to the amount that will more likely than not be realized.

The Company recognizes tax liabilities from an uncertain tax position only if it is more likely than not that the tax position will not be sustained upon examination by the taxing authorities, based on the technical merits of the tax position. There are no uncertain tax positions that have been recognized in the accompanying unaudited condensed financial statements. The Company is required to file tax returns in the U.S. federal jurisdiction and in the state of District of Columbia. The Company’s policy is to recognize interest and penalties related to uncertain tax benefits, if any, as part of income tax expense. No such interest and penalties have been accrued as of March 31, 2021 and December 31, 2020.

Recent Accounting Pronouncements

The Company’s management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the accompanying unaudited condensed financial statements.

Note 3—Initial Public Offering

On October 23, 2020, the Company consummated its Initial Public Offering of 40,250,000 Units, including 5,250,000 Over-Allotment Units, at $10.00 per Unit, generating gross proceeds of $402.5 million, and incurring offering costs of approximately $22.8 million, inclusive of approximately $14.1 million in deferred underwriting commissions.

Each Unit consists of one share of Class A common stock, and one-third of one redeemable warrant (each, a “Public Warrant”). Each Public Warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 6).

Note 4—Related Party Transactions

Founder Shares

On September 9, 2020, the Sponsor paid $25,000 to cover for certain offering costs on behalf of the Company in exchange for issuance of 11,500,000 shares of the Company’s Class B common stock, par value $0.0001 per share, (the “Founder Shares”). On September 14, 2020, the Company effectuated an 0.75-for-1 reverse split of the Founder Shares, resulting in an aggregate outstanding amount of 8,625,000 Founder Shares. On October 20, 2020, the Company effectuated a 6-for-7 stock split of the founder shares, resulting in an aggregate outstanding amount of 10,062,500 Founder Shares (see Note 8). All shares and associated amounts have been adjusted to reflect the stock splits. The initial stockholders agreed to forfeit, after giving effect to the stock split that occurred on October 20, 2020, up to 1,312,500 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The underwriter exercised its over-allotment option in full on October 23, 2020; thus, these 1,312,500 Founder Shares were no longer subject to forfeiture.

13

SUPERNOVA PARTNERS ACQUISITION COMPANY, INC.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The initial stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (1) one year after the completion of the initial Business Combination and (2) the date on which the Company consummates a liquidation, merger, capital stock exchange, reorganization, or other similar transaction after the initial Business Combination that results in all of the stockholders having the right to exchange their shares of common stock for cash, securities or other property. Notwithstanding the foregoing, if the last reported sale price of the common stock shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, the Founder Shares will be released from the lock-up.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 6,700,000 Private Placement Warrants at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $10.1 million.

Each whole Private Placement Warrant is exercisable for one whole share of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants to the Sponsor was added to the proceeds from the Initial Public Offering to be held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable for cash (except in certain limited circumstances) and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination.

Related Party Loans

On September 9, 2020, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan is non-interest bearing and payable upon the completion of the Initial Public Offering. The Company had borrowed approximately $183,000 under the Note and fully repaid the Note on October 23, 2020.

In addition, in order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company may repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of March 31, 2021 and December 31, 2020, the Company had no borrowings under the Working Capital Loans.

Forward Purchase Agreements

In connection with the closing of the Company’s Initial Public Offering, the Company entered into forward purchase agreements to which the Company’s Sponsors committed to purchase the Company’s Class A common stock in an aggregate amount equal to 5,000,000 shares of common stock, plus an aggregate of 1,666,667 warrants to purchase one share of Class A common stock at $11.50 per share, for an aggregate purchase price of $50,000,000, or $10.00 for one share of Class A common stock and one-third of one warrant, in a private placement that is conditioned upon, and will be consummated concurrently with, the Closing.

Note 5—Commitments and Contingencies

Registration rights

The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans, if any (and any shares of Class A common stock issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans and upon conversion of the Founder Shares), are entitled to registration rights pursuant to a registration rights agreement. These holders are entitled to certain demand and “piggyback” registration rights. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting agreement

The underwriters were entitled to an underwriting discount of $0.20 per unit, or approximately $8.1 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per unit, or approximately $14.1 million in the aggregate will be payable to the underwriters for deferred underwriting commissions.

The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Risks and uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these unaudited condensed financial statements. The unaudited condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 6—Derivative Liabilities

As of March 31, 2021 and December 31, 2020, the Company 13,416,667 and 6,700,000 Public Warrants and Private Warrants outstanding, respectively.

Public Warrants may only be exercised in whole and only for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination and (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the issuance of the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, the Company will use its commercially reasonable efforts to file with the SEC and have an effective registration statement covering the shares of Class A common stock issuable upon exercise of the warrants and to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed. If a registration statement covering the Class A common stock issuable upon exercise of the warrants is not effective by the 60th business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the above, if the Company’s shares of Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elect, it will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. The Public Warrants will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation.

The warrants have an exercise price of $11.50 per share, subject to adjustments. In addition, if (x) the Company issues additional shares of Class A common stock or equity-linked securities (excluding the potential forward purchase securities as described in the prospectus) for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share of Class A common stock (with such issue price or effective issue price to be determined in good faith by the board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume-weighted average trading price of the Class A common stock during the 10-trading day period starting on the trading day after the day on which the Company consummated the initial business Combination (such price, the “Market Value”) is below $9.20 per share, then the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price described below under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of Class A common stock issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable so long as they are held by the Sponsor or its permitted transferees, except in certain limited circumstances. If the Private Placement Warrants are held by someone other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00:

Once the warrants become exercisable, the Company may redeem the outstanding warrants for cash (except as described herein with respect to the Private Placement Warrants):

The Company will not redeem the warrants as described above unless a registration statement under the Securities Act covering the issuance of the shares of Class A common stock issuable upon exercise of the warrants is then effective and a current prospectus relating to those shares of common stock is available throughout the 30-day redemption period, except if the warrants may be exercised on a cashless basis and such cashless exercise is exempt from registration under the Securities Act.

Redemption of warrants for when the price per share of Class A common stock equals or exceeds $10.00:

Once the warrants become exercisable, the Company may redeem the outstanding warrants:

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

The “fair market value” of Class A common stock shall mean the volume-weighted average price of Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 shares of Class A common stock per warrant (subject to adjustment).

In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Note 7—Stockholders’ Equity

Preferred Stock— The Company is authorized to issue 1,000,000 shares of preferred stock, par value $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of March 31, 2021 and December 31, 2020, there were no shares of preferred stock issued or outstanding.

Class A Common Stock— The Company is authorized to issue 100,000,000 shares of Class A common stock with a par value of $0.0001 per share. As of March 31, 2021 and December 31, 2020, there were 40,250,000 shares of Class A common stock issued or outstanding including 34,004,650 and 33,488,198 shares subject to possible redemption that were classified as temporary equity in the accompanying condensed balance sheets, respectively.

Class B Common Stock— The Company is authorized to issue 20,000,000 shares of Class B common stock with a par value of $0.0001 per share. On September 9, 2020, the Company issued 11,500,000 shares of Class B common stock. On September 14, 2020, the Company effectuated an 0.75-for-1 reverse split of the Founder Shares, resulting in an aggregate outstanding amount of 8,625,000 Founder Shares. On October 20, 2020, the Company effectuated a 6-for-7 stock split of the founder shares, resulting in an aggregate outstanding amount of 10,062,500 Founder Shares. All shares and associated amounts have been adjusted to reflect the stock splits. Of these, up to 1,312,500 shares of Class B common stock are subject to forfeiture, to the Company by the initial stockholders for no consideration to the extent that the underwriter’s over-allotment option is not exercised in full or in part, so that the number of shares of Class B common stock would collectively equal 20% of the Company’s issued and outstanding common stock after the Initial Public Offering. The underwriter exercised its over-allotment option in full on October 23, 2020; thus, these 1,312,500 shares of Class B common stock were no longer subject to forfeiture.

Only holders of Class B common stock will have the right to elect directors or remove directors prior to the completion of the initial Business Combination. These provisions in the amended and restated certificate of incorporation may only be amended by a resolution passed by the holders of a majority of the Class B common stock. Holders of the Class A common stock and holders of the Class B common stock of record are entitled to one vote for each share held on all other matters to be voted on by stockholders, including any vote in connection with the initial Business Combination, and vote together as a single class, except as required by law or the applicable rules of the NYSE.

The Class B common stock will automatically convert into Class A common stock at the time of the initial Business Combination on a one-for-one basis, subject to increase in respect of the issuance of certain securities, as provided herein. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amount issued in the Initial Public Offering and related to the closing of the initial Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock

will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the aggregate number of all shares of common stock outstanding upon the completion of the Initial Public Offering, plus the aggregate number of shares of Class A common stock and equity-linked securities issued or deemed issued in connection with the initial Business Combination (net of the number of shares of Class A common stock redeemed in connection with the initial Business Combination), excluding the forward purchase securities and any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination and any private placement warrants issued to the Sponsor, an affiliate of our sponsor or any of the Company’s officers or director. As of March 31, 2021 and December 31, 2020, there were 10,062,500 shares of Class B common stock issued and outstanding.

Note 8—Fair Value Measurements

The following tables present information about the Company’s assets that are measured at fair value on a recurring basis and indicate the fair value hierarchy of the valuation techniques that the Company utilized to determine such fair value.

March 31, 2021

December 31, 2020

Transfers to/from Levels 1, 2, and 3 are recognized at the beginning of the reporting period. There were no transfers to/from Levels 1,2, and 3 for the three months ended March 31, 2021.

Level 1 instruments include investments in mutual funds invested in government securities and Public Warrants. The Company uses inputs such as actual trade data, benchmark yields, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

The fair value of the Public Warrants issued in connection with the Public Offering and Private Placement Warrants were initially and subsequently measured at fair value using a Monte Carlo simulation model. The fair value of the forward purchase agreements is determined as the estimated unit value less the net present value of the forward purchase agreements. For the three months ended March 31, 2021, the Company recognized a non-cash gain resulting from a decrease in the fair value of liabilities of approximately $8.4 million presented as change in fair value of derivative liabilities on the accompanying unaudited condensed statement of operations.

The estimated fair value of the Private Placement Warrants, forward purchase agreements and the Public Warrants prior to being separately listed and traded, is determined using Level 3

inputs. Inherent in a Monte Carlo simulation are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero.
