Keryx Biopharmaceuticals, Inc.
Notes to Condensed Consolidated Financial Statements
(unaudited)
 
Unless the context requires otherwise, references in this report to “Keryx,” “Company,” “we,” “us” and “our” refer to Keryx Biopharmaceuticals, Inc. and our subsidiaries.
NOTE 1 – DESCRIPTION OF BUSINESS
We are a commercial stage biopharmaceutical company focused on bringing innovative medicines to people with kidney disease. Our long-term vision is to build a multi-product kidney care company. Our marketed product, Auryxia ® (ferric citrate) tablets, is an orally available, absorbable, iron-based medicine. Auryxia is approved by the U.S. Food and Drug Administration, or FDA, for two indications; the medication was originally approved in September 2014 for the control of serum phosphorus levels in patients with chronic kidney disease, or CKD, on dialysis. The FDA approved Auryxia tablets for an additional indication in November 2017 for the treatment of iron deficiency anemia in adults with CKD, not on dialysis. With two FDA-approved indications, we will leverage our U.S. clinical and commercial infrastructure to make Auryxia available to millions of people with CKD. Ferric citrate is also approved in Japan under the trade name Riona ® and marketed by our Japanese partner, Japan Tobacco, Inc., or JT, and its subsidiary, Torii Pharmaceutical Co., Ltd., or Torii, and approved in Europe as Fexeric ® . Our vision of building a multi-product kidney care company includes expansion of our product portfolio with other medicines that can help patients with kidney disease.
NOTE 2 – BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they may not include all of the information and footnotes required by GAAP for complete financial statements. All adjustments that are, in the opinion of management, of a normal recurring nature and are necessary for a fair presentation of these interim financial statements have been included. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2016 . The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for the entire fiscal year or any other interim period.
Principles of Consolidation
The condensed consolidated financial statements include our financial statements and those of our wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of these condensed consolidated financial statements and the reported amounts of revenues and expenses during the applicable reporting period. Actual results could differ from those estimates. Such differences could be material to these condensed consolidated financial statements.
Revenue Recognition
Our primary source of revenue during the reporting periods was product sales. We sell product to a limited number of major wholesalers, our Distributors, as well as certain pharmacies, or collectively, our Customers. Our Distributors resell the product to retail pharmacies for purposes of their reselling the product to fill patient prescriptions. In accordance with GAAP, our revenue recognition policy requires that (i) there is persuasive evidence that an arrangement exists between us and the Customer, (ii) delivery has occurred, (iii) collectability is reasonably assured, and (iv) the price is fixed or determinable. In the fourth quarter of 2016, we began to recognize revenue under the pull-through (ex-factory) method based on sales to our Customers as a result of our ability to reasonably estimate product returns based on our prior sales and product return history.

5



Prior to the fourth quarter of 2016, we recognized revenue based on the resale of Auryxia for the purposes of filling patient prescriptions, and not based on initial sales from us to our Customers as we did not have sufficient history such that we could reliably estimate product returns based on sales to our Customers. As a result, prior to the fourth quarter of 2016, we deferred Auryxia revenue recognition until the earlier of the product being resold for purposes of filling patient prescriptions and the expiration of the right of return (twelve months after the expiration date of the product). The deferred revenue was recorded net of discounts, rebates, and chargebacks. We also deferred the related cost of product sales and recorded such amounts as finished goods inventory held by others, which was included in inventory on our condensed consolidated balance sheet, until revenue related to such product sales was recognized.
Our U.S. Auryxia product sales for the three and nine months ended September 30, 2017 and 2016 were offset by provisions for allowances and accruals as set forth in the tables below.

Reclassifications
Certain amounts in the table above for the nine months ended September 30, 2017 , which also appear in Management's Discussion and Analysis of Financial Condition and Results of Operations, have been reclassified for consistency. Specifically, fees paid to a Customer during the three months ended March 31, 2017 totaling $0.5 million that were included in the caption "Rebates, chargebacks and discounts" were reclassified to the caption "Trade allowances" for the nine months ended September 30, 2017 . Total product sales allowances for the nine months ended September 30, 2017 were not affected.
Basic and Diluted Net Loss Per Common Share
Basic net loss per share is computed by dividing the losses allocable to common stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share does not reflect the effect of shares of common stock to be issued upon the exercise of stock options, as their inclusion would be anti-dilutive.

The following table presents amounts that were excluded from the calculation of diluted net loss per share, due to their anti-dilutive effect:

New Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or the FASB, or other standard setting bodies that we adopt as of the specified effective date.
In May 2014, the FASB issued Accounting Standards Update, or ASU, No. 2014-09, Revenue from Contracts with Customers (Topic 606) , a comprehensive new standard which amends revenue recognition principles and provides a single set of criteria for revenue recognition among all industries. The new standard provides a five-step framework whereby revenue is recognized when promised goods or services are transferred to a customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires enhanced disclosures pertaining to revenue recognition in both interim and annual periods. The standard is effective for interim and annual periods beginning after December 15, 2017 and allows for adoption using a full retrospective method, or a modified retrospective method. The FASB has subsequently issued amendments to ASU No. 2014-09 that have the same effective date and transition date of January 1, 2018. We expect to adopt these standards using the modified retrospective method. We have identified the customer contracts that are in the scope of these standards, including contracts with our distributors and specialty pharmacies, as well as contracts with third-party payers. We are in the process of reviewing the contracts to assess the potential impact of these standards. Prior to January 1, 2018, we plan to complete our review of the identified customer contracts as well as our license agreements to determine the impact that these standards will have on our financial position, results of operations and disclosures.
In February 2016, the FASB issued ASU No. 2016-02, Leases . The new standard requires that all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The new standard will be effective for us on January 1, 2019. The adoption of this standard may have a material impact on our financial position as it may impact the amount of our assets and liabilities. We are currently evaluating the potential impact that this standard may have on our results of operations.
In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . The new standard addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard will be effective for us on January 1, 2018. This standard is not expected to have a material impact on our statement of cash flows upon adoption.

Cash equivalents as of September 30, 2017 and December 31, 2016 consisted of institutional money market funds. The carrying value of our money market funds approximates fair value due to their short-term maturities.

Debt
In October 2015, we issued $125 million in Convertible Senior Notes, due 2020, or the Notes, in a private financing to funds managed by Baupost Group Securities, L.L.C., or Baupost. As of September 30, 2017 and December 31, 2016 , the fair value of the Notes was $237 million and $196 million , respectively, which differs from their carrying value. The fair value of the Notes is influenced by our stock price and stock price volatility. See Note 9 – Debt for additional information on our debt obligations.

NOTE 5 – STOCKHOLDERS’ EQUITY (DEFICIT)
Change in Stockholders’ Equity (Deficit)
Total stockholders’ equity was $9.0 million at September 30, 2017 , which is an increase of $17.3 million during the nine months ended September 30, 2017 as compared to stockholders’ deficit at December 31, 2016 of $8.3 million . This increase was primarily attributable to the proceeds from the issuance of common stock of $75.7 million , the reclassification of the derivative liability related to the Notes to equity of $62.7 million and $10.7 million related to stock-based compensation expense, partially offset by our net loss of approximately $133.0 million .

Stock-based compensation costs capitalized as part of inventory were immaterial for the three and nine months ended September 30, 2017 and 2016 .
The fair value of stock options granted is estimated at the date of grant using the Black-Scholes pricing model. The expected term of options granted is derived from historical data, the expected vesting period and the full contractual term. Expected volatility is based on the historical volatility of our common stock. The risk-free interest rate is based on the U.S. Treasury Yield for a period consistent with the expected term of the option in effect at the time of the grant. We have assumed no expected dividend yield, as dividends have never been paid to stock or option holders and will not be paid for the foreseeable future.
The weighted average grant date fair value of stock options granted during the three months ended September 30, 2017 and 2016 was $5.14 and $5.94 per share, respectively, and during the nine months ended September 30, 2017 and 2016 was $3.91 and $4.54 per share, respectively. We used historical information to estimate forfeitures of stock options. As of September 30, 2017 , there was $10.7 million and $6.3 million of total unrecognized compensation cost related to non-vested stock options and restricted stock, respectively, which is expected to be recognized over weighted-average periods of 1.7 years and 1.6 years , respectively. These amounts do not include 4,338,750 unvested options and 435,000 shares of unvested restricted stock as of September 30, 2017 which are performance-based and vest upon achievement of certain corporate milestones. Stock-based compensation for these awards will be measured and recorded if and when it is probable that the milestone will be achieved.
NOTE 7 – LICENSE AGREEMENTS
In November 2005, we entered into a license agreement with Panion & BF Biotech, Inc., or Panion. Under the license agreement, we acquired the exclusive worldwide rights, excluding certain Asian-Pacific countries, for the development and marketing of ferric citrate. To date, we have paid an aggregate of $11.6 million of milestone payments to Panion. In addition, Panion is eligible to receive royalty payments based on a mid-single digit percentage of net sales of ferric citrate in the licensed territory, as well as a manufacturing fee for product manufactured for use in the licensed territory.
In September 2007, we entered into a Sublicense Agreement with JT and Torii, under which JT and Torii obtained the exclusive sublicense rights for the development and commercialization of ferric citrate in Japan. JT and Torii are responsible for the future development and commercialization costs in Japan. Effective June 8, 2009, we entered into an Amended and Restated Sublicense Agreement, or Revised Agreement, with JT and Torii, which, among other things, provided for the elimination of all significant on-going obligations under the Sublicense Agreement.
In January 2014, JT and Torii received manufacturing and marketing approval of ferric citrate from the Japanese Ministry of Health, Labour and Welfare. Ferric citrate launched in May 2014 and is marketed in Japan by Torii under the brand name Riona and is indicated as an oral treatment for the improvement of hyperphosphatemia in patients with CKD. Under the terms of the Revised Agreement, we receive royalty payments based on a tiered double-digit percentage of net sales of Riona in Japan escalating up to the mid-teens and may also receive up to an additional $55.0 million upon the achievement of certain annual net sales milestones. In accordance with our revenue recognition policy, royalty revenues are recognized in the quarter that JT and Torii provide their written report and related information to us regarding sales of Riona, which generally will be one quarter following the quarter in which the underlying sales by JT and Torii occurred. For the three months ended September 30, 2017 and 2016 , we recorded $1.4 million and $1.3 million , respectively, in license revenue related to royalties earned on net sales of Riona in Japan. For the nine months ended September 30, 2017 and 2016 , we recorded $3.7 million and $3.5 million , respectively, in license revenue related to royalties earned on net sales of Riona in Japan. We record the associated mid-single digit percentage of net sales royalty expense due Panion, the licensor of ferric citrate, in the same period as the royalty revenue from JT and Torii is recorded. For each of the three months ended September 30, 2017 and 2016 , we recorded $0.8 million in license expense related to royalties due to the licensor of ferric citrate relating to sales of Riona in Japan. For the nine months

ended September 30, 2017 and 2016 , we recorded $2.2 million and $2.1 million , respectively, in license expense related to royalties due to the licensor of ferric citrate relating to sales of Riona in Japan.

NOTE 9 – DEBT
In October 2015, we completed the sale of $125 million of Notes due 2020, in a private placement, or the Private Placement, to funds managed by Baupost pursuant to a Notes Purchase Agreement dated October 14, 2015. The Notes were issued under an Indenture, or the Indenture, dated as of October 15, 2015, with The Bank of New York Mellon Trust Company, N.A. as trustee, or the Trustee. The Indenture subjects us to certain financial and business covenants and contains restrictions on the payments of cash dividends.
The Indenture contains customary terms and events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving us) occurs and is continuing, the Trustee by notice to us, or the holders of at least 25% in aggregate principal amount of the outstanding Notes by written notice to us and the Trustee, may declare 100% of the principal on all of the Notes to be due and payable. Upon such a declaration of acceleration, such principal will be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving us, 100% of the principal on all of the Notes will become due and payable automatically.
Further, in connection with the Private Placement, we entered into a Registration Rights Agreement with the purchasers of the Notes, or the Registration Rights Agreement, pursuant to which we agreed to (i) file a registration statement, or the Resale Registration Statement with the Securities and Exchange Commission, or SEC, covering the resale of the Notes and the underlying common stock into which the Notes are convertible upon the written request of Baupost, and (ii) use commercially reasonable efforts, subject to receipt of necessary information from all the purchasers of the Notes, to cause the SEC to declare the Resale Registration Statement effective. Further, the Registration Rights Agreement permits Baupost to demand from time to time that we file a shelf Registration Statement pursuant to Rule 415 of the Securities Act from which any number of shelf takedowns may be conducted upon written request from Baupost. Finally, the Registration Rights Agreement affords Baupost certain piggyback registration rights.
The Notes are convertible at the option of Baupost at an initial conversion rate of 267.3797 shares of our common stock per $1,000 principal amount, equal to a conversion price of $3.74 per share, which represents the last reported sale price of our stock on October 14, 2015. The conversion rate is subject to adjustment from time to time upon the occurrence of certain events. Further, upon the occurrence of certain fundamental changes involving us, Baupost may require us to repurchase for cash all or part of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased.
At issuance, a portion of the Notes was contingently convertible into cash if our stockholders did not approve an increase in the number of authorized shares of our common stock by July 1, 2016. In accordance with accounting guidance for debt with a conversion option, we separated the conversion option from the debt instrument and accounted for it separately as a derivative liability, due to the Notes initially being partially convertible to cash at the option of Baupost. We allocated the proceeds between the debt component and the embedded conversion option (the derivative) by performing a valuation of the derivative as of the transaction date, which was determined based on the difference between the fair value of the Notes with the conversion option and the fair value of the Notes without the conversion option. The fair value of the derivative liability was recognized as a debt discount and the carrying amount of the convertible senior notes represented the difference between the proceeds from the issuance of the Notes and the fair value of the derivative liability on the date of issuance. The excess of the principal amount of the debt component over its carrying amount, or debt discount, was amortized to interest expense using the effective interest method over the expected life of the debt.
We determined the expected life of the debt was equal to the period through July 1, 2016, as this represented the earliest point at which a portion of the Notes was initially contingently convertible into cash. Accordingly, for the nine months ended September 30, 2016 , approximately $34.2 million of interest expense was recognized related to the Notes, all of which was attributable to the amortization of the debt discount.
Following our 2016 Annual Meeting of Stockholders held on May 25, 2016, we filed a certificate of amendment to our certificate of incorporation with the Secretary of State of the State of Delaware to increase the number of authorized shares of our common stock to allow for the full conversion of the Notes into our common stock. On April 10, 2017, we entered into the First Supplemental Indenture, or the First Supplement, to the Indenture. Under the terms of the First Supplement, the Notes issued under the Indenture were not convertible by the holders thereof until on or after June 8, 2017, except in connection with a “fundamental change” as defined in the Indenture. After June 8, 2017, the Notes are convertible entirely into shares of our common stock or cash depending upon the number of shares of our common stock authorized at the time of such conversion. At our 2017 Annual Meeting of Stockholders held on June 8, 2017, our stockholders ratified the filing and effectiveness of the certificate of amendment filed in May 2016. In addition, at the meeting our stockholders also approved a separate amendment to our certificate of incorporation to increase the number of authorized shares of our common stock to 230,000,000 shares. As a result, the full amount of the Notes is convertible into shares of our common stock. The holders of the Notes may, at their option, convert the Notes until the maturity date thereof.
In accordance with accounting guidance for debt modifications and exchanges, we assessed the terms of the First Supplement and determined that it resulted in a modification. During the three months ended June 30, 2017, we separated the conversion option from the debt instrument and accounted for it separately as a derivative liability, due to the Notes being contingently convertible to cash at the option of Baupost per the terms of the First Supplement. We allocated the proceeds between the debt component and the embedded conversion option (the derivative) by performing a valuation of the derivative as of the date of the First Supplement, which was determined based on the difference between the fair value of the Notes with the conversion option and the fair value of the Notes without the conversion option. The fair value of the derivative liability was recognized as a debt discount and the carrying amount of the convertible senior notes represented the difference between the principal amount of the Notes and the fair value of the derivative liability on the date of the First Supplement. The excess of the principal amount of the debt component over its carrying amount, or debt discount, was amortized to interest expense using the effective interest method over the expected life of the debt. We determined the expected life of the debt was equal to the period through June 8, 2017, as this represented the point at which the Notes was contingently convertible into cash.
In the nine months ended September 30, 2017 and 2016 , $63.0 million and $34.2 million , respectively, of interest expense was recognized related to the Notes. As of September 30, 2017 and December 31, 2016 , the balance of the Notes and the carrying value of the Notes was $125 million , and the fair value of the Notes was $237 million and $196 million , respectively.

NOTE 11 – COMMITMENTS AND CONTINGENCIES
Commitments
As of September 30, 2017 , our contractual obligations and commitments primarily consist of our obligations under non-cancelable leases, the Notes and various agreements with third parties, including selling, general and administrative, research and development and manufacturing agreements.
Contingencies
We accrue a liability for legal contingencies when we believe that it is both probable that a liability has been incurred and that we can reasonably estimate the amount of the loss. We review these accruals and adjust them to reflect the best information available at the time. To the extent new information is obtained and our views on the probable outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in our accrued liabilities would be recorded in the period in which such determination is made. For the matters referenced below, a liability is not probable or the amount cannot be reasonably estimated and, therefore, an accrual has not been made. In addition, in accordance with the relevant authoritative guidance, for any matters in which the likelihood of material loss is at least reasonably possible, we will provide disclosure of the possible loss or range of loss. If a reasonable estimate cannot be made, however, we will provide disclosure to that effect. We expense legal costs as they are incurred.
Four purported class action lawsuits have been filed against us and certain of our current and former officers (Gregory P. Madison, Scott A. Holmes, Ron Bentsur, and James Oliviero).  Three of these actions were filed in the U.S. District Court for the Southern District of New York, captioned respectively Terrell Jackson v. Keryx Biopharmaceuticals, Inc., et al., No. 1:16-cv-06131, filed on August 2, 2016, Richard J. Erickson v. Keryx Biopharmaceuticals, Inc., et al. No. 1:16-cv-06218, filed on August 4, 2016, and Richard King v. Keryx Biopharmaceuticals, Inc., et al., No. 1:16-cv-06233, filed on August 5, 2016. The Jackson complaint purports to be brought on behalf of stockholders who purchased our common stock between February 25, 2016 and August 1, 2016, the Erickson complaint purports to be brought on behalf of stockholders who purchased our common stock between March 2, 2016 and July 29, 2016, and the King complaint purports to be brought on behalf of stockholders who purchased our common stock between February 25, 2016 and July 29, 2016. On August 26, 2016, the fourth complaint, captioned Tim Karth v. Keryx Biopharmaceuticals, Inc., et al., No. 1:16-cv-11745, was filed in the U.S. District Court for the District of Massachusetts, which complaint was subsequently amended. The Karth complaint purports to be brought on behalf of stockholders who purchased our common stock between May 8, 2013 and August 1, 2016. The Jackson, Erickson and King matters were transferred to the U.S. District Court for the District of Massachusetts on April 5, 2017. Each complaint generally alleges that we and certain of our current and former officers violated Sections 10(b) and/or 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder by making allegedly false and/or misleading statements concerning us and our business operations and future prospects in light of the August 1, 2016 announcement of an interruption in our supply of Auryxia. Two stockholder derivative complaints were also filed on December 16, 2016 against us and certain of our current and former officers (Gregory P. Madison, Scott A. Holmes, Ron Bentsur and James Oliviero), certain of our current directors (Kevin J. Cameron, Daniel P. Regan, Steven C. Gilman, Michael Rogers and John P. Butler) and our former directors (Michael P. Tarnok, Joseph Feczko, Jack Kaye and Wyche Fowler, Jr.), in the Superior Court of Massachusetts, one captioned Venkat Vara Prasad Malledi v. Keryx Biopharmaceuticals, Inc., et al., No. 16-3865 and one captioned James Anderson v. Keryx Biopharmaceuticals, Inc., et al., No. 16-3866.  Each of these two complaints generally allege that the individual defendants breached their fiduciary duties owed to us, unjustly enriched themselves by their actions, abused their control positions with us, mismanaged us and wasted corporate assets since July 31, 2013 in light of our August 1, 2016 announcement by us of an interruption in the supply of the our product Auryxia. On June 27, 2017, the Superior Court granted the parties' motion to consolidate and stay the derivative litigations. All of the complaints seek unspecified damages, interest, attorneys’ fees, and other costs. We deny any allegations of wrongdoing and intend to vigorously defend against these lawsuits. There is no assurance, however, that we or the other defendants will be successful in our defense of either of these lawsuits or that insurance will be available or adequate to fund any settlement or judgment or the litigation costs of these actions. Moreover, we are unable to predict the outcome or reasonably estimate a range of possible losses at this time. A resolution of these lawsuits adverse to us or the other defendants, however, could have a material effect on our financial position and results of operations in the period in which the particular lawsuit is resolved.

OVERVIEW
We are a commercial stage biopharmaceutical company focused on bringing innovative medicines to people with kidney disease. Our long-term vision is to build a multi-product kidney care company. Our marketed product, Auryxia (ferric citrate) tablets, is an orally available, absorbable, iron-based medicine. Auryxia is approved by the U.S. Food and Drug Administration, or FDA, for two indications; the medication was originally approved in September 2014 for the control of serum phosphorus levels in patients with chronic kidney disease, or CKD, on dialysis. The FDA approved Auryxia tablets for an additional indication in November 2017 for the treatment of iron deficiency anemia in adults with CKD, not on dialysis. With two FDA-approved indications, we will leverage our U.S. clinical and commercial infrastructure to make Auryxia available to millions of people with CKD. Ferric citrate is also approved in Japan under the trade name Riona and marketed by our Japanese partner, Japan Tobacco, Inc., or JT, and its subsidiary, Torii Pharmaceutical Co., Ltd., or Torii, and approved in Europe as Fexeric. Our vision of building a multi-product kidney care company includes expansion of our product portfolio with other medicines that can help patients with kidney disease.
RECENT DEVELOPMENTS
On November 6, 2017, the FDA approved Auryxia for the treatment of iron deficiency anemia in adults with CKD, not on dialysis. The approval of Auryxia for a second indication significantly increases the number of patients in the United States that can benefit from Auryxia. Upon receipt of this approval, we made Auryxia available to these patients and we plan to leverage our existing U.S. commercial infrastructure to sell Auryxia in this indication.
OUR STRATEGY
Our business is focused on creating long-term stockholder value by bringing differentiated medicines for the treatment of people with kidney disease to the market that provide meaningful benefits to patients and their healthcare providers. The three pathways to our strategy are:
Maximize Auryxia's Potential
We developed and subsequently launched Auryxia in the United States in late December 2014. Auryxia is approved by the FDA for two indications. It is a non-calcium, non-chewable, orally-administered phosphate binder for patients with CKD on dialysis; Auryxia is also approved for treatment of iron deficiency anemia in adults with CKD, not on dialysis. Auryxia is the first FDA-approved oral iron medication to treat iron deficiency anemia in CKD patients, not on dialysis. Auryxia is being marketed in the United States to nephrologists and renal care teams through our specialty salesforce and commercial infrastructure. In the United States, there are approximately 450,000 adult patients with CKD requiring dialysis (referred to as End Stage Renal Disease, or ESRD), including approximately 350,000 adults currently taking a phosphate binder. We estimate that in the United States, approximately 1.7 million adults under the care of a nephrologist have iron deficiency anemia, not on dialysis, including approximately 650,000 adults currently being treated by nephrologists for iron deficiency anemia. Iron deficiency anemia is common in the non-dialysis population and the prevalence and severity increases as CKD advances. Iron deficiency anemia is symptomatic and can significantly impact quality of life. There is significant literature that correlates anemia with increased risk of heart disease and death. Our field-based organization is aligned to 95 territories calling on target nephrologists and their associated dialysis centers. We believe strong fundamentals are in place to drive commercial adoption of Auryxia in the dialysis setting and maximize the potential of Auryxia as a treatment of iron deficiency anemia in adults with CKD, not on dialysis.
Expand Our Portfolio
We will evaluate opportunities to expand our product portfolio with other medicines that can help patients with kidney disease. Our business development activities include evaluating several clinical-drug candidates and commercial medicines to in-license or acquire to add to our portfolio and provide us with new commercial opportunities. We will seek to add assets that leverage the infrastructure we have built to support our foundational medicine, Auryxia, including our clinical development and commercial teams. We believe these efforts have the potential to provide additional revenues to us in the future.
Manage Growth and Talent
We are committed to creating a culture of success and continue to engage a workforce of high-quality and talented people to support our potential growth.

Financial Performance Overview
Net U.S. Auryxia product sales represents the gross product sales of Auryxia in the United States less provisions for product sales allowances and accruals. These provisions include trade allowances, rebates, chargebacks and discounts, product returns and other incentives.
Our license revenue consists of license fees, royalties, and milestone payments arising from our agreement with JT and Torii. Royalty revenue consists of royalties received from JT and Torii on net sales of Riona in Japan. Based on our agreement with JT and Torii, and in accordance with our revenue recognition policy described below, royalty revenues are recognized in the quarter that JT and Torii provide their written report and related information to us regarding sales of Riona, which generally will be one quarter following the quarter in which the underlying sales by JT and Torii occurred.
Cost of goods sold includes the cost of active pharmaceutical ingredient, or API, for Auryxia on which product sales were recognized during the period, the associated costs for tableting, packaging, shipment, insurance and quality assurance, as well as any idle capacity charges we may incur at our contract manufacturers and write-offs of inventory that fails to meet specifications or is otherwise no longer suitable for commercial manufacture. Cost of goods sold also includes expenses due to the licensor of Auryxia related to the manufacturing of product and product sales recognized during the period.
Our license expense consists of royalties due to the licensor of Auryxia related to our license agreement with JT and Torii. License expense is recognized in the same period as the license revenue is recorded.
Our research and development expenses consist primarily of salaries and related personnel costs, including stock-based compensation, fees paid to consultants and outside service providers for clinical and laboratory development, manufacturing, including pre-approval inventory build-up, regulatory, facilities-related and other expenses relating to the design, development, manufacture, testing, and enhancement of our drug candidates and technologies, as well as expenses related to in-licensing of new product candidates. We expense our research and development costs as they are incurred.
Our selling, general and administrative expenses consist primarily of salaries and related expenses, including stock-based compensation, for executive, finance, sales, marketing and other administrative personnel, recruitment expenses, professional fees and other corporate expenses, including investor relations, legal activities, pre-commercial/commercial activities and facilities-related expenses.
Our results of operations include stock-based compensation expense as a result of the grants of stock options and restricted stock. Stock-based compensation expense for awards of options and restricted stock granted to employees and directors represents the fair value of the award recorded over the respective vesting periods of the individual awards. The expense is classified by expense categories in the condensed consolidated statements of operations. We expect to continue to incur significant stock-based compensation expenses.
Even though our trials demonstrated that Auryxia is effective in the control of serum phosphorus levels in patients with CKD on dialysis and treating iron deficiency anemia in certain patients in the non-dialysis setting, there is no guarantee that we will be able to record meaningful commercial sales of Auryxia in the future or become profitable. In addition, we expect losses to continue as we continue to fund the development and commercialization of Auryxia, including, but not limited to, building of inventory, commercial activities, ongoing and additional clinical trials, and the potential acquisition and development of additional drugs or drug candidates in the future. As we continue our development efforts, we may enter into additional third-party collaborative agreements and may incur additional expenses, such as licensing fees and milestone payments. As a result, our quarterly results may fluctuate and a quarter-by-quarter comparison of our operating results may not be a meaningful indication of our future performance.
GENERAL CORPORATE
We have devoted substantially all of our efforts to the identification, in-licensing, development and partnering of drug candidates, as well as pre-commercial/commercial activities related to Auryxia, and have incurred negative cash flow from operations each year since our inception. We have spent, and expect to continue to spend, substantial amounts in connection with implementing our business strategy, including our product development efforts, our clinical trials, commercial, partnership and licensing activities. Prior to the U.S. launch of Auryxia in late December 2014, we had not commercialized any drug. Our ability to achieve profitability depends on a number of factors, including our ability to complete our development efforts, obtain any additional regulatory approvals which we may seek for our drug, successfully complete any post-approval regulatory obligations and successfully manufacture and commercialize our drug. We may continue to incur substantial operating losses even after we begin to generate meaningful revenues from our drug.

CRITICAL ACCOUNTING POLICIES
The discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities and related disclosure of contingent assets and liabilities at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the applicable period. On an ongoing basis, we evaluate our estimates and judgments, including those related to net product revenue and related reserves, stock-based compensation, accruals for clinical research organizations and clinical site costs, inventory, net accounts receivable and accounting related to goodwill.  We base our estimates on historical experience, known trends and events and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
For a discussion of our critical accounting estimates, please see Part II, Item 7 " Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies " of our Annual Report on Form 10-K for the year ended December 31, 2016. There have been no material changes to these critical accounting estimates as described in that Form 10-K.

Gross Auryxia product sales increased for the three months ended September 30, 2017 as compared to the same period in 2016 primarily as a result of an increase in patient prescriptions and related units sold, partially offset by a higher gross-to-net adjustment. Provisions for product sales allowances and accruals as a percentage of gross Auryxia product sales for the three months ended September 30, 2017 as compared to the same period in 2016 increased primarily as a result of a higher percentage of sales through government (Medicare Part D) contracts that generally receive a larger rebate. Our gross-to-net adjustments may increase depending on our mix of business between Medicare Part D and commercial payers as well as the portion of our business coming from the use of Auryxia as a treatment for hyperphosphatemia as compared to the portion of our business coming from the use of Auryxia as a treatment for iron deficiency anemia.
Beginning in the fourth quarter of 2016, we began to recognize revenue under the pull-through (ex-factory) method based on sales to our customers as a result of our ability to reasonably estimate product returns.
License Revenue. For the three months ended September 30, 2017 and 2016 , we recognized $1.4 million and $1.3 million , respectively, in license revenue on royalty payments from sales of Riona in Japan.
Cost of Goods Sold . For the three months ended September 30, 2017 , we recognized $5.9 million in cost of goods sold, as compared to $18.2 million for the three months ended September 30, 2016 . This decrease was primarily due to a decrease of $12.7 million in inventory write-offs in the 2017 period as compared to the 2016 period, partially offset by additional units sold in the 2017 period as compared to the 2016 period.
License Expense . For each of the three months ended September 30, 2017 and 2016 , we recognized $0.8 million in license expense related to royalties due to the licensor of Auryxia relating to sales of Riona in Japan.
Research and Development Expenses . Research and development expenses increased by $0.6 million to $9.3 million for the three months ended September 30, 2017 , as compared to $8.7 million for the three months ended September 30, 2016 . The increase in research and development expenses was primarily due to an increase in process development-related manufacturing costs as we seek to increase our manufacturing capabilities, as well as clinical trial costs related to the treatment of iron deficiency anemia patients. We expect our research and development expenses will increase for the remainder of 2017 as compared to the three months ended September 30, 2017 , due to continued process development-related manufacturing costs, as well as our investments in investigator sponsored research and other clinical trial costs.
Selling, General and Administrative Expenses . Selling, general and administrative expenses increased by $2.2 million to $22.7 million for the three months ended September 30, 2017 , as compared to $20.5 million for the three months ended September 30, 2016 . The increase was primarily due to an increase in personnel costs attributable to the continued commercialization of Auryxia, as well as costs associated with preparing for the approval and launch of Auryxia for the treatment of iron deficiency anemia in adults with CKD, not on dialysis. We expect our selling, general and administrative costs

17



to increase slightly for the remainder of 2017 as compared to the three months ended September 30, 2017 , due to costs associated with supporting the launch of Auryxia for the treatment of iron deficiency anemia.
Other income (expense) . Other income (expense) for each of the three months ended September 30, 2017 and September 30, 2016 was $0.2 million in income.
Income Taxes.  For each of the three months ended September 30, 2017 and 2016 , we recognized $20,000 in income tax expense related to the recording of a deferred tax liability associated with capitalized goodwill, an indefinite-lived intangible asset that is being amortized for tax purposes.

Nine months ended September 30, 2017 and September 30, 2016
Net U.S. Auryxia Product Sales. For the nine months ended September 30, 2017 , we recognized $38.2 million in product sales of Auryxia, net of allowances, discounts, incentives, rebates and chargebacks, as compared with $18.9 million for the nine months ended September 30, 2016 .

Gross Auryxia product sales increased for the nine months ended September 30, 2017 as compared to the same period in 2016 primarily as a result of an increase in patient prescriptions and related units sold, partially offset by a higher gross-to-net adjustment. Provisions for product sales allowances and accruals as a percentage of gross Auryxia product sales for the nine months ended September 30, 2017 as compared to the same period in 2016 increased primarily as a result of a higher percentage of sales through government (Medicare Part D) contracts that generally receive a larger rebate.
As noted above, beginning in the fourth quarter of 2016, we began to recognize revenue under the pull-through (ex-factory) method based on sales to our customers as a result of our ability to reasonably estimate product returns.
License Revenue. For the nine months ended September 30, 2017 , we recognized $3.7 million in license revenue on royalty payments from sales of Riona in Japan as compared to $3.5 million for the nine months ended September 30, 2016 . This increase was due to increased sales by JT and Torii of Riona in Japan.
Cost of Goods Sold . For the nine months ended September 30, 2017 , we recognized $14.5 million in cost of goods sold, as compared to $24.4 million for the nine months ended September 30, 2016 . This decrease was primarily due to a decrease of $14.7 million in inventory write-offs in the 2017 period as compared to the 2016 period, partially offset by additional units sold during the 2017 period as compared to the 2016 period.
License Expense . For the nine months ended September 30, 2017 , we recognized $2.2 million in license expense related to royalties due to the licensor of Auryxia relating to sales of Riona in Japan as compared to $2.1 million for the nine months ended September 30, 2016 . This increase was due to an increase in sales of Riona in Japan during the 2017 period.
Research and Development Expenses . Research and development expenses increased by $1.8 million to $25.1 million for the nine months ended September 30, 2017 , as compared to $23.3 million for the nine months ended September 30, 2016 . The increase in research and development expenses was primarily due to an increase in process development-related manufacturing

18



costs as we seek to increase our manufacturing capabilities, as well as an increase in filing fees in the first quarter of 2017 related to our submission of the supplemental new drug application to the FDA for Auryxia.
Selling, General and Administrative Expenses . Selling, general and administrative expenses increased by $9.3 million to $70.8 million for the nine months ended September 30, 2017 , as compared to $61.5 million for the nine months ended September 30, 2016 . The increase was primarily due to an increase in personnel costs attributable to the continued commercialization of Auryxia and costs associated with preparing for the approval and launch of Auryxia for the treatment of iron deficiency anemia in adults with CKD, not on dialysis.
Other income (expense) . Other income (expense) for the nine months ended September 30, 2017 was $62.3 million in expense as compared to $38.4 million in expense for the nine months ended September 30, 2016 . The increase was primarily due to an increase in the amortization of the debt discount of $29.0 million offset by a change in the fair value adjustment to the derivative liability related to our convertible senior notes of $5.0 million.
Income Taxes.  For each of the nine months ended September 30, 2017 and 2016 , we recognized $60,000 in income tax expense related to the recording of a deferred tax liability associated with capitalized goodwill, an indefinite-lived intangible asset that is being amortized for tax purposes.
LIQUIDITY AND CAPITAL RESOURCES
Our major sources of cash have been proceeds from various public and private offerings of our common stock, the issuance of convertible senior notes, from the upfront and milestone payments from our agreement with JT and Torii, sales of Auryxia, option and warrant exercises, interest income, and miscellaneous payments from our other prior licensing activities. The commercial launch of our product, Auryxia, occurred in late December 2014 and we began to recognize revenue from the sales of Auryxia in 2015. On November 6, 2017, the FDA approved Auryxia for the treatment of iron deficiency anemia in adults with CKD, not on dialysis, expanding the number of patients which can benefit from Auryxia. Even if we successfully commercialize Auryxia, including in the non-dialysis setting, we may not become profitable. Our ability to achieve profitability depends on a number of factors, including our ability to complete our development efforts, obtain any additional regulatory approvals which we may seek for our drug, successfully complete any post-approval regulatory obligations and successfully manufacture and commercialize our drug alone or in partnership. We may continue to incur substantial operating losses even after we begin to generate meaningful revenues from Auryxia.
In November 2016, we filed a registration statement on Form S-3 (No. 333-214513), which the Securities and Exchange Commission, or SEC, declared effective on December 6, 2016, which registered the issuance from time to time of up to $250 million of our securities. At that time, we also entered into a Controlled Equity Offering SM Sales Agreement, or the Sales Agreement, with Cantor Fitzgerald & Co., as sales agent, or Cantor Fitzgerald, pursuant to which we were initially able to offer and sell, from time to time, through Cantor Fitzgerald, shares of our common stock having an aggregate offering price of up to $75.0 million. During the six months ended June 30, 2017, we sold 11,574,320 shares under the Sales Agreement for aggregate net proceeds of $73.1 million. The sales during the six months ended June 30, 2017 amounted to the initial $75.0 million issuable pursuant to the Sales Agreement. In July 2017, we filed a new prospectus supplement with the SEC relating to the Sales Agreement under which we may offer and sell, from time to time, through Cantor Fitzgerald, shares of our common stock having an additional aggregate offering price of up to $75.0 million. During the three months ended September 30, 2017, we sold 362,854 shares under the Sales Agreement for aggregate net proceeds of $2.6 million. The initial $75.0 million of common stock issued pursuant to the Sales Agreement and the additional $75.0 million of common stock is included as part of the $250 million registered on the registration statement referred to above.
In October 2015, we completed the sale of $125 million of Convertible Senior Notes due 2020, or the Notes, to funds managed by The Baupost Group, L.L.C, or Baupost. See Note 9 – Debt for a description of the Notes. We also entered into a Registration Rights Agreement with the purchasers of the Notes, or the Registration Rights Agreement, pursuant to which we agreed to (i) file a registration statement with the SEC covering the resale of the Notes and the underlying common stock which the Notes are convertible into upon the written request of Baupost, and (ii) use commercially reasonable efforts, subject to receipt of necessary information from all the purchasers of the Notes, to cause the SEC to declare such resale registration statement effective. Further, the Registration Rights Agreement permits Baupost to demand from time to time that we file a shelf Registration Statement pursuant to Rule 415 of the Securities Act from which any number of shelf takedowns may be conducted upon written request from Baupost. In addition, the Registration Rights Agreement provides Baupost certain piggyback registration rights.
As of September 30, 2017 , we had $114 million in cash and cash equivalents, as compared to $112 million in cash and cash equivalents at December 31, 2016 , representing an increase of $2.0 million . The increase in cash and cash equivalents was primarily due to net proceeds from sales of our common stock under the Sales Agreement as discussed above, partially offset by cash used to fund operations.
We currently expect that our existing capital resources, future anticipated cash flows from product sales and the funds from future financings will be sufficient to execute our current business objectives. The actual amount of cash that we will need to operate our business is subject to many factors, including, but not limited to, the timing and expenditures associated with commercial activities related to Auryxia and the timing and magnitude of cash received from product sales, the timing and expenditures associated with the build-up of inventory and capacity expansion, and the timing, design and conduct of any further clinical trials for Auryxia. As a result of these factors, we will need to seek additional financing to provide the cash necessary to execute our current operations, including beyond commercializing Auryxia, and to develop and commercialize any drugs or drug candidates we may in-license or acquire. For a detailed discussion regarding the risks and uncertainties related to our liquidity and capital resources, please refer to our Risk Factor, “Our existing capital resources may not be adequate to finance our operating cash requirements for the length of time that we have estimated” and the other risk factors contained in this report.
Net cash used in operating activities for the nine months ended September 30, 2017 was $73.3 million as compared to $66.3 million net cash used in operating activities for the same period in 2016 . This increase in net cash used in operating activities was primarily related to an increase in net loss after non-cash adjustments, as well as increases in prepaid manufacturing costs and purchases of inventory.
Net cash used in investing activities for the nine months ended September 30, 2017 was $1.2 million as compared to $2.1 million net cash used in investing activities for the same period in 2016 . The net cash used in investing activities for the nine months ended September 30, 2017 and 2016 relates to purchases of property, plant and equipment in connection with certain leasehold improvements.
Net cash provided by financing activities for the nine months ended September 30, 2017 was $76.7 million as compared to $0.2 million for the same period in 2016. Net cash provided by financing activities for the nine months ended September 30, 2017 is attributable to the net proceeds from the issuance of common stock under the Sales Agreement.

OBLIGATIONS AND COMMITMENTS
As of September 30, 2017 , our contractual obligations and commitments primarily consist of our obligations under non-cancelable leases, the Notes, and various agreements with third parties, including selling, general and administrative, research and development and manufacturing agreements.
There have been no other material changes to our contractual obligations and commitments outside the ordinary course of business from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016 .
Leases
In April 2015, we signed a lease agreement for approximately 27,300 square feet in Boston, Massachusetts, for a 94-month term that commenced on May 1, 2015. In order to make the space usable for our operations, substantial improvements were made. Our landlord agreed to pay for up to approximately $1.9 million of the improvements, and we bore all additional costs that were incurred. As such, we have determined that we are the owner of the improvements and account for tenant improvements paid by our landlord as a lease incentive. On May 1, 2015, in accordance with the Financial Accounting Standards Board's Accounting Standards Codification 840-20, Operating Leases , we recorded a deferred lease incentive, and an associated receivable from our landlord, for the total amount to be paid by the landlord for improvements. The deferred lease incentive is being amortized as a partial offset to rent expense over the term of the lease, and the receivable was drawn down as cash was received from our landlord. We began occupying the space in November 2015. Improvements made to our leased space have been recorded as fixed assets and will be amortized over the assets’ useful lives or the remaining lease term, whichever is shorter.
Royalty and Contingent Milestone Payments
Under the license agreement with Panion & BF Biotech, Inc., or Panion, we acquired the exclusive worldwide rights, excluding certain Asian-Pacific countries, for the development and marketing of ferric citrate. As of September 30, 2017 , we have paid an aggregate of $11.6 million of milestone payments to Panion, including the $2.0 million paid upon European marketing approval in 2015. In addition, Panion is eligible to receive royalty payments based on a mid-single digit percentage of net sales of Auryxia in the United States and of Riona in Japan. We record royalties on net sales of Auryxia in cost of goods sold and royalties on net sales of Riona in license expense.
OFF-BALANCE SHEET ARRANGEMENTS
We have not entered into any transactions with unconsolidated entities whereby we have financial guarantees, subordinated retained interests, derivative instruments or other contingent arrangements that expose us to material continuing risks, contingent liabilities, or any other obligations under a variable interest in an unconsolidated entity that provides us with financing, liquidity, market risk or credit risk support, or engages in leasing, hedging, or research and development services on our behalf.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
INTEREST RATE RISK
The primary objective of our investment activities is to preserve principal while maximizing our income from investments and minimizing our market risk. As of September 30, 2017 , our portfolio of financial instruments consists of cash equivalents, which includes money market funds. Due to the short-term nature of these financial instruments, we believe there is no material exposure to interest rate risk, and/or credit risk, arising from our portfolio of financial instruments.
EQUITY PRICE RISK
The Notes include conversion provisions that are based on the price of our common stock at conversion or at maturity of the Notes. The fair values of the Notes are dependent on the price and volatility of our common stock and will generally increase or decrease as the market price of our common stock changes.
ITEM 4. CONTROLS AND PROCEDURES
EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES
As of September 30, 2017 , management carried out, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Our disclosure controls and procedures are designed to provide reasonable assurance that information we are required to disclose in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2017 , our disclosure controls and procedures were effective.
CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING
There were no changes in our internal control over financial reporting during the three months ended September 30, 2017 , that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
LIMITATIONS ON EFFECTIVENESS OF CONTROLS
Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within our company have been detected.

PART II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
See Note 11 – Commitments and Contingencies to our condensed consolidated financial statements included in this report, which is incorporated into this item by reference.
ITEM 1A. RISK FACTORS
You should carefully consider the following risks and uncertainties. If any of the following occurs, our business, financial condition and/or operating results could be materially harmed. These factors could cause the trading price of our common stock to decline, and you could lose all or part of your investment.

Risks related to our business and industry
We have a limited operating history as a commercial-stage company and have incurred substantial operating losses since our inception. We expect to continue to incur losses in the future and may never become profitable.
We have a limited operating history as a commercial-stage company. You should consider our prospects in light of the risks and difficulties frequently encountered by early stage companies. In addition, we have incurred substantial operating losses since our inception and expect to continue to incur operating losses for the foreseeable future and may never become profitable. As of September 30, 2017, we had an accumulated deficit of $968.1 million. As we continue our research and development and commercial efforts, we may incur increasing losses. We may continue to incur substantial operating losses even after we begin to generate meaningful revenues from our drug, Auryxia. Our ability to achieve profitability depends on a number of factors, including our ability to complete our development efforts, obtain any additional regulatory approvals that we may seek for our drug, successfully complete any post-approval regulatory obligations and successfully manufacture and commercialize our drug.
We are highly dependent on the commercial success of Auryxia in the United States for the foreseeable future and as a result we may be unable to attain profitability and positive cash flow from operations.
In September 2014, the U.S. Food and Drug Administration, or FDA, approved Auryxia for the control of serum phosphorus levels in patients with chronic kidney disease, or CKD, on dialysis and in November 2017, the FDA approved Auryxia for the treatment of iron deficiency anemia in adults with CKD, not on dialysis. The commercial success of Auryxia will depend on a number of factors, including:
the effectiveness of Auryxia as a treatment for adult patients with CKD on dialysis and for iron deficiency anemia in adults with CKD, not on dialysis;
the adoption of Auryxia by physicians, which depends on whether physicians view it as a safe and effective treatment for their patients;
our ability to successfully launch Auryxia in the newly approved indication of iron deficiency anemia in adults with CKD, not on dialysis;
the effectiveness of the sales, managed markets and marketing efforts by us and our competitors;
our ability to continue to supply Auryxia to the market without interruption;
our ability to identify reliable suppliers and successfully manufacture Auryxia;
our ability to continue to grow Auryxia product sales following the resupply of Auryxia to the market following the recent interruption in its supply;
the size of the treatable patient population;
our ability to both secure and maintain adequate reimbursement for, and optimize patient access to Auryxia by providing third-party payers with a strong value proposition and the benefits of Auryxia to patients;
our mix of business between private commercial payers and government-sponsored plans;
the occurrence of any side effects, adverse reactions or misuse, or any unfavorable publicity in these areas, associated with Auryxia;
our ability to obtain and maintain strong intellectual property protection for Auryxia; and

21



the development or commercialization of competing products.
Our revenues from the commercialization of Auryxia are subject to these and other factors, and therefore may be unpredictable from quarter-to-quarter. Ultimately, we may never generate sufficient revenues from Auryxia to reach or maintain profitability or sustain our anticipated levels of operations.
We have limited experience as a company in sales and marketing, and with respect to pricing and obtaining adequate third-party reimbursement and as a result we may be unable to effectively market our product and retain market access.
We currently have limited experience as a company in sales and marketing and with respect to pricing and obtaining adequate third-party reimbursement for drugs. In order to market Auryxia, including in the newly approved indication of iron deficiency anemia in adults with CKD, not on dialysis, we intend to continue to expand our marketing organization and hire additional sales representatives, which will require substantial effort and significant management and financial resources. We will need to devote significant effort, in particular, to recruiting individuals with experience in the sales and marketing of pharmaceutical products. Competition for personnel with these skills is intense and may be particularly difficult for us as no oral drug has previously been specifically marketed for the treatment of iron deficiency anemia in patients with CKD, not on dialysis.
Approval of Fexeric (ferric citrate coordination complex) in the European Union does not ensure successful commercialization and reimbursement.
On September 23, 2015, the European Commission, or EC, approved Fexeric (ferric citrate coordination complex) for the control of elevated serum phosphorus levels, or hyperphosphatemia, in adult patients with CKD, including pre-dialysis and dialysis patients. The EC also considered ferric citrate coordination complex as a New Active Substance, or NAS, which provides 10 years of data and marketing exclusivity in the European Union, or EU.
We are not currently marketing Fexeric in the EU, however, we are seeking potential partners to commercialize Fexeric in the EU. We cannot assure you that we will be able to find a commercialization partner in the EU or that we will be able to agree to acceptable terms with any partner to launch and commercialize Fexeric in the EU. If we do not begin to market Fexeric in the EU by September 23, 2018, the EC may withdraw its approval of Fexeric.
The commercial success of Fexeric is subject to the same risks we face with commercializing Auryxia in the United States. In addition, in European countries, pricing and payment of prescription pharmaceuticals is subject to more extensive governmental control than in the United States. Pricing negotiations with European governmental authorities can take six to 12 months or longer after the receipt of regulatory approval and product launch. If reimbursement for Fexeric is unavailable in any country in which reimbursement is sought, limited in scope or amount, or if pricing is set at or reduced to unsatisfactory levels, our ability or any potential partner’s ability to successfully commercialize Fexeric in such a country would be impacted negatively.  Furthermore, if these measures prevent us or any potential partner from selling Fexeric on a profitable basis in a particular country, they could prevent the commercial launch or continued sale of Fexeric in that country.
Our potential revenues from the commercialization of Fexeric in the EU are subject to these and other factors, and therefore we may never reach or maintain profitability in the EU.
Auryxia may cause undesirable side effects or have other properties that could limit its commercial potential.
The most commonly reported adverse reactions in the clinical trials that supported the approval of Auryxia for CKD on dialysis in the United States included diarrhea (21%), discolored feces (19%), nausea (11%), constipation (8%), vomiting (7%), and cough (6%). Gastrointestinal adverse reactions were the most common reason for discontinuing Auryxia (14%) in clinical trials for that indication. The most commonly reported adverse reactions in the clinical trials that supported the approval of Auryxia in the United States for iron deficiency anemia in adults with CKD, not on dialysis included discolored feces (22%), diarrhea (21%), constipation (18%), nausea (10%), abdominal pain (5%) and hyperkalemia (5%). Diarrhea was the most common reason for discontinuing Auryxia (2.6%) in clinical trials for the iron deficiency anemia in adults with CKD, not on dialysis indication. If we or others identify previously unknown side effects, if known side effects are more frequent or severe than in the past, if we or others detect unexpected safety signals for Auryxia or any products perceived to be similar to Auryxia, or if any of the foregoing are perceived to have occurred, then:
sales of Auryxia may be impaired;
regulatory approvals for Auryxia may be restricted or withdrawn;
we may decide to, or be required to, send drug warnings or safety alerts to physicians, pharmacists and hospitals, or we may decide to conduct a product recall;
reformulation of the product, additional nonclinical or clinical studies, changes in labeling or changes to or re-approvals of manufacturing facilities may be required;

22



we may be precluded from pursuing additional development opportunities to enhance the clinical profile of Auryxia within its indicated populations, as well as be precluded from studying Auryxia in additional indications and populations or in new formulations; and
government investigations or lawsuits, including class action suits, may be brought against us. 
Any of the above occurrences would harm or prevent sales of Auryxia, likely increase our expenses and impair our ability to successfully commercialize Auryxia.
Furthermore, as we explore development opportunities to enhance the clinical profile of Auryxia, any clinical trials conducted, if successful, may expand the patient populations treated with Auryxia within or outside of its current indications or patient populations, which could result in the identification of previously unknown side effects, increased frequency or severity of known side effects, or detection of unexpected safety signals.  In addition, as Auryxia is commercialized, we expect it will be used in wider populations and in less rigorously controlled environments than in clinical studies. As a result, regulatory authorities, healthcare practitioners, third-party payers or patients may perceive or conclude that the use of Auryxia is associated with serious adverse effects, undermining our commercialization efforts.
We rely on third parties to manufacture and analytically test our drug. If these third parties do not successfully manufacture and test our drug, our business will be harmed.
We have limited experience in manufacturing products for clinical or commercial purposes. We intend to continue, in whole or in part, to use third parties to manufacture and analytically test our drug for commercial distribution and use in clinical trials. We may not be able to enter into future contract agreements with these third-parties on terms acceptable to us, if at all.
Our ability to conduct clinical trials, manufacture and commercialize our drug will depend on the ability of such third parties to manufacture our drug on a large scale at a competitive cost and in accordance with the current good manufacturing practices, or cGMPs, and other regulatory requirements, including requirements from federal, state and local environmental and safety regulatory agencies and foreign regulatory requirements, if applicable. Significant scale-up of manufacturing may result in unanticipated technical challenges and will require validation studies that are subject to FDA inspection. Scale-up and technology transfer activities can be complex, and insufficient process knowledge can result in a poorly scaled up process with inadequate process control. A lack of process control can lead to increased deviations during the manufacturing process, out of specification test results, batch rejection and the possible distribution of drug products that do not conform to predetermined specifications. In addition, a variety of factors can affect a contract manufacturer’s qualifications to produce acceptable product, including deficiencies in the contractor’s quality unit, lack of training, a shortage of qualified personnel, capacity constraints and changes in the contractor’s commercial or quality related priorities. Any of these difficulties, if they occur, and are not overcome to the satisfaction of the FDA or other regulatory agency, could lead to an interruption in the supply of our drug to the market, particularly given that some of the third parties we intend to employ in the manufacturing process are single source providers. As a result of the large quantity of materials required for Auryxia production and the large quantities of Auryxia that is required for our commercial success, the commercial viability of Auryxia will also depend on adequate supply of starting materials that meet quality, quantity and cost standards and the ability of our contract manufacturers to continually produce the active pharmaceutical ingredient, or API, and finished drug product on a commercial scale. Failure to achieve and maintain these levels of supply can jeopardize and prevent the successful commercialization of the product. Moreover, issues that may arise in our scale-up and technology transfer of Auryxia and continued commercial scale manufacture of Auryxia may lead to significant delays in our development and commercial timelines and negatively impact our financial performance. For example, a production-related issue resulted in an interruption in the supply of Auryxia in the third and fourth quarters of 2016. This supply interruption negatively impacted our revenues in 2016. Although we have resolved this supply interruption and taken steps designed to prevent future interruptions in the supply of Auryxia, any additional supply interruptions would negatively and materially impact our reputation and financial condition.
We currently have multiple suppliers of Auryxia’s API and two suppliers with three approved sites for the supply of Auryxia drug product. We are currently utilizing one of these suppliers at its two approved sites to manufacture Auryxia drug product, are working with this supplier to have a third site approved and are conducting additional development work at the other supplier. If any of our suppliers were to limit or terminate production, or otherwise fail to meet the quality or delivery requirements needed to supply Auryxia at adequate levels, we could experience losses of revenue, which could materially and adversely impact our results of operations.
Our third-party manufacturers may not perform as required under the terms of our supply agreement or quality agreement, or may not remain in the contract manufacturing business for the time required by us to successfully manufacture and distribute our drug. In addition, our contract manufacturers will be subject to ongoing periodic and unannounced inspections by the FDA and corresponding foreign governmental agencies to ensure strict compliance with cGMPs, as well as other governmental regulations and corresponding foreign standards. While we periodically audit our contractors for adherence to regulatory requirements, and are ultimately held responsible for their regulatory compliance, we cannot assure you that

23



unforeseen changes at these contractors will not occur that could change their regulatory standing. The same issues apply to contract analytical services which we use for quality, impurity and release testing of our drug. We are required by law to establish adequate oversight and control over raw materials, components and finished products furnished by our third-party manufacturers, which we establish by contract, supplier qualification and periodic audits, but unforeseen circumstances could affect our third-party manufacturers’ compliance with applicable regulations and standards. As we continue to scale up production, we continue to develop analytical tools for Auryxia drug substance and drug product testing. Failure to develop effective analytical tools could result in regulatory or technical delay or could jeopardize our ability to obtain and maintain FDA approval. Moreover, even with effective analytical methods available, there is no assurance that we will be able to analyze all the raw materials and qualify all impurities to the satisfaction of the FDA, possibly requiring additional analytical studies, analytical method development, or preclinical studies, which could significantly delay our ability to receive regulatory approvals for our drug. Additionally, changes in the analytical specifications required by the FDA or other regulatory authority, such as United States Pharmacopeial Convention standards, from time to time, could delay our ability to receive regulatory approvals for our drug or our commercial efforts.
In addition, switching or engaging multiple third-party contractors to produce our drug substance or drug product may be difficult and time consuming because the number of potential manufacturers may be limited and the process by which multiple manufacturers make the drug substance or drug product must meet established specifications at each manufacturing facility. It may be difficult and time consuming for us to find and engage replacement or multiple manufacturers quickly and on terms acceptable to us, if at all. For Auryxia, the loss of any of our drug substance or drug product manufacturers would result in significant additional costs and delays in our development program and as demonstrated by our recent interruption in the supply of Auryxia, negatively impact our sales of Auryxia.
If we do not establish or maintain manufacturing, drug development and marketing arrangements with third parties, we may be unable to commercialize our products.
We do not possess all of the capabilities to fully commercialize our product on our own. From time to time, we may need to contract with additional third parties, or renew or revise contracts with existing third parties, to:
manufacture our drug;
assist us in developing, testing and obtaining regulatory approval for and commercializing our compound and technologies; and
market and distribute our drug.
We can provide no assurance that we will be able to successfully enter into agreements with such third parties on terms that are acceptable to us, if at all. If we are unable to successfully contract with third parties for these services when needed, or if existing arrangements for these services are terminated, whether or not through our actions, or if such third parties do not fully perform under these arrangements, we may have to delay, scale back or end one or more of our drug development programs or seek to develop or commercialize our product independently, which could result in significant delays. Furthermore, such failure could result in the termination of license rights to our product. If these manufacturing, development or marketing agreements take the form of a partnership or strategic alliance, such arrangements may provide our collaborators with significant discretion in determining the efforts and resources that they will apply to the development and commercialization of our product. We cannot predict the form or scope that any such collaboration might take, and we may pursue other strategic alternatives if terms or proposed collaborations are not attractive. To the extent that we rely on third parties to research, develop or commercialize our product, we are unable to control whether such product will be scientifically or commercially successful. Additionally, if these third parties fail to perform their obligations under our agreements with them or fail to perform their work in a satisfactory manner, in spite of our efforts to monitor and ensure the quality of such work, we may face decreased sales and/or delays in achieving the business or regulatory milestones required for additional commercialization of our current drug and any future drug candidate.
We will incur significant liability if it is determined that we are promoting any “off-label” use of Auryxia.
Physicians are permitted to prescribe drug products for uses that are not described in the product’s labeling and that differ from those approved by the FDA or other applicable regulatory agencies. Such “off-label” uses are common across medical specialties. Although the FDA and other regulatory agencies do not regulate a physician’s choice of treatments, the FDA and other regulatory agencies do restrict communications on the subject of off-label use. Companies are not permitted to promote drugs for off-label uses or promote drugs using marketing claims that are not otherwise consistent with the FDA-approved labeling, including comparative or superiority claims that are not consistent with the FDA-approved labeling or supported by substantial evidence. Accordingly, we may not promote Auryxia in the United States for use in any indications other than for the control of serum phosphorus levels in patients with CKD on dialysis and for the treatment of iron deficiency anemia in adults with CKD, not on dialysis, and all promotional claims must be consistent with the FDA-approved labeling for Auryxia. The FDA and other regulatory and enforcement authorities actively enforce laws and regulations prohibiting promotion of off-

24



label uses and the promotion of products for which marketing approval has not been obtained as well as the false advertising or misleading promotion of drugs. A company that is found to have improperly promoted off-label uses or to have otherwise engaged in false or misleading promotion of drugs will be subject to significant liability, including civil and administrative remedies as well as criminal sanctions.
Notwithstanding the regulatory restrictions on off-label promotion, the FDA and other regulatory authorities allow companies to engage in truthful, non-misleading, and non-promotional scientific exchange concerning their products in certain circumstances. We intend to engage in medical education activities and communicate with healthcare providers in compliance with all applicable laws, regulatory guidance and industry best practices. Although we believe we have put in place a robust compliance program designed to ensure that all such activities are performed in a legal and compliant manner, Auryxia is our first commercial product, so our implementation of our compliance program in connection with commercialization activities is still relatively new.
The status of reimbursement from third-party payers for newly approved health care drugs is uncertain and failure to obtain adequate reimbursement could limit our ability to generate revenue.
Our ability to commercialize pharmaceutical products may depend, in part, on the extent to which reimbursement for the products will be available from:
government and health administration authorities;
private health insurers;
managed care programs; and
other third-party payers.
Significant uncertainty exists as to the coverage and reimbursement status of newly approved health care products, as well as the timing of coverage and reimbursement decisions by third-party payers. Third-party payers, including Medicare and Medicaid, are challenging the prices charged for medical products and services. Government and other third-party payers increasingly are attempting to contain health care costs by limiting both coverage and the level of reimbursement for new drugs and by refusing, in some cases, to provide coverage for uses of approved products for disease indications for which the FDA has not granted labeling approval. In 2003, Congress passed the Medicare Prescription Drug, Improvement and Modernization Act of 2003, which for the first time established prescription drug coverage for Medicare beneficiaries, under Medicare Part D. Under this program, beneficiaries purchase insurance coverage from private insurance companies to cover the cost of their prescription drugs. Likewise, current and future legislative or regulatory efforts to control or reduce healthcare costs or reform government healthcare programs, such as the Patient Protection Affordable Care Act, or PPACA, and the Health Care and Education Reconciliation Act of 2010, could result in lower prices or rejection of coverage and reimbursement for our drug. In addition, third-party insurance coverage may not be available to patients for our product. If government and other third-party payers do not provide adequate coverage and reimbursement levels for our product, Auryxia’s market acceptance may be significantly reduced. In addition, the mix of our business that is reimbursed by different payers can negatively impact our net U.S. Auryxia product sales on a year-to-year and quarter-to-quarter basis with a larger mix of government payers generally increasing our adjustments to gross Auryxia sales in the particular period.
If we fail to comply with healthcare regulations, we could face substantial penalties and our business, operations and financial condition could be adversely affected.
As a manufacturer of pharmaceuticals, even though we do not (and do not expect in the future to) control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payers, certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. We are subject to healthcare fraud and abuse and patient privacy regulation by both the federal government and the states in which we conduct our business.  These regulations include:
federal healthcare program anti-kickback laws, which prohibit, among other things, persons from soliciting, receiving or providing remuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs such as Medicare and Medicaid;
federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent, and which may apply to entities like us which provide coding and billing advice to customers;
the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which prohibits executing a scheme to defraud any healthcare benefit program or making false statements relating to

25



healthcare matters and which also imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information;
the Federal Food, Drug, and Cosmetic Act, or FDCA, which among other things, strictly regulates drug product marketing, prohibits manufacturers from marketing drug products for off-label use and regulates the distribution of drug samples;
state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payer, including commercial insurers, and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by federal laws, thus complicating compliance efforts;
the federal Foreign Corrupt Practices Act which prohibits corporations and individuals from paying, offering to pay, or authorizing the payment of anything of value to any foreign government official, government staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity; and
the federal Physician Payments Sunshine Act, which was passed as part of the Patient Protection and Affordable Care Act of 2010, and similar state laws in certain states, that require pharmaceutical and medical device companies to monitor and report certain payments and transfers of value made to physicians and teaching hospitals.
If our operations are found to be in violation of any of the laws described above or any other laws, rules or regulations that apply to us, we will be subject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment or restructuring of our operations could adversely affect our ability to operate our business and our financial results.
We have assembled an experienced compliance team and implemented a compliance program based on industry best practices designed to ensure our commercialization of Auryxia complies with all applicable laws, regulations and industry standards. We also hire, manage and incentivize our employees around a culture of compliance, trust, respect and ownership. Because our compliance program is relatively new and the requirements in this area are constantly evolving, we cannot be certain that our compliance program will eliminate all areas of potential exposure. Although compliance programs can mitigate the risk of investigation and prosecution for violations of these laws, the risks cannot be entirely eliminated. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business, as well as damage our business or reputation. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security, fraud and reporting laws may prove costly.
If our competitors develop and market products that are less expensive, have a reduced pill burden, more effective or safer than our drug product, or our drug product does not achieve market acceptance vis-à-vis existing treatments, our commercial opportunities may be reduced or eliminated.
The pharmaceutical industry is highly competitive. Our competitors include pharmaceutical companies and biotechnology companies, as well as universities and public and private research institutions. In addition, companies that are active in different but related fields represent substantial competition for us. Many of our competitors have significantly greater capital resources, larger research and development staffs and facilities and greater experience in drug development, regulation, manufacturing and marketing drugs than we do. These organizations also compete with us to recruit qualified personnel, attract partners for joint ventures or other collaborations, and license technologies that are competitive with ours. As a result, our competitors may be able to more easily develop technologies and products that could render our drug product obsolete or noncompetitive. To compete successfully in this industry, we must identify novel and unique drugs or methods of treatment and then acquire and/or complete the development of those drugs as treatments in advance of our competitors.
Auryxia is competing in the United States with other FDA-approved phosphate binders such as Renagel ® (sevelamer hydrochloride) and Renvela ® (sevelamer carbonate), both marketed by Genzyme Corporation (a wholly-owned subsidiary of Sanofi), or Genzyme, PhosLo ® (calcium acetate), marketed by Fresenius Medical Care, Fosrenol (lanthanum carbonate), marketed by Shire Pharmaceuticals Group plc, and Velphoro (sucroferric oxyhydroxide), marketed by Fresenius Medical Care North America, as well as over-the-counter calcium carbonate products such as TUMS and metal-based options such as aluminum and magnesium. Our strategy to compete against these existing treatments depends in part on physicians and patients accepting that Auryxia is differentiated in the marketplace versus these FDA-approved phosphate binders. In addition, we may have to compete against existing treatments on price, which becomes more challenging as generic versions of these existing treatments come to market. There are several parties that have received approval of Abbreviated New Drug Applications, or ANDAs, for generic Renvela with the FDA and launched the generic form in the United States. In addition, a generic

26



formulation of PhosLo® manufactured by Roxane Laboratories, Inc. was launched in the United States in October 2008. In addition, upon the expiration of its core patents, generic formulations of Fosrenol may be launched. These generic formulations could have a further material effect on the pricing of phosphate binders.
Auryxia is also competing in the United States with other FDA-approved treatments for iron deficiency anemia, such as Venofer ® (iron sucrose) and Injactafer ® (ferric carboxymaltose), both marketed by American Regent (a registered trademark of Luitpold Pharmaceuticals, Inc., a member of the Daiichi Sankyo Group), Feraheme ® (ferumoxytol), marketed by AMAG Pharmaceuticals, Inc., Triferic ® (ferric pyrophosphate citrate), marketed by Rockwell Medical, Inc., over-the-counter iron supplement products, as well as Erythropoiesis-stimulating agents, or ESAs, including Procrit ® (epoetin alfa), marketed by Janssen Products, LP (a wholly-owned subsidiary of Johnson & Johnson) and Aranesp ® (darbepoetin alfa), marketed by Amgen Inc.
Furthermore, our commercial opportunities may be reduced or eliminated if our competitors develop and market products that are less expensive, more effective or safer than our drug product. Other companies have drug candidates in various stages of pre-clinical or clinical development to treat diseases for which we are marketing our drug and also seeking to acquire and develop other drug products. Even if we are successful in developing effective drugs, our product(s) may not compete successfully with products produced by our competitors.
If we lose our key personnel or are unable to attract and retain additional personnel, our operations could be disrupted and our business could be harmed.
As of September 30, 2017 we had 206 full and part-time employees. To successfully develop and commercialize our drug and any drug candidates we may in-license or acquire, we must be able to attract and retain highly skilled personnel. Our limited resources may hinder our efforts to attract and retain highly skilled personnel. In addition, if we lose the services of our current personnel our ability to continue to execute on our business plan could be materially impaired.
Greg Madison has been our Chief Executive Officer since April 30, 2015. Previously, Mr. Madison was appointed to our Board of Directors in March 2015. Mr. Madison joined Keryx in February 2014 as Executive Vice President and Chief Operating Officer to transition Keryx from a development stage organization into a fully-integrated commercial entity, and bring to Keryx a wealth of relevant expertise in both the phosphate binder and iron deficiency anemia markets.
Brian Adams joined Keryx in April 2014 as General Counsel and was additionally appointed as our Corporate Secretary in March 2015.
In April 2015, we appointed John F. Neylan, M.D., as our Senior Vice President and Chief Medical Officer.
In July 2015, we appointed Scott Holmes as our Senior Vice President and Chief Financial Officer. In January 2017, we appointed Christine Carberry as our Chief Operating Officer.
Although we have employment agreements with Greg Madison, Brian Adams, John F. Neylan, M.D., Scott Holmes and Christine Carberry, these agreements do not prevent them from terminating their employment with us.

Risks associated with our product development efforts
If we are unable to successfully complete our clinical trial programs, or if such clinical trials take longer to complete than we project, our ability to execute our current business strategy will be adversely affected.
Although we are not currently conducting registration trials for Auryxia, we continue to conduct clinical trials and post-marketing testing of Auryxia and we may have to complete the development of any product candidate that we develop, in-license or acquire in the future. As a result, the continued marketing of Auryxia and the clinical development of any other product is subject to the risks associated with the pre-clinical and clinical development of pharmaceutical products.
Whether or not and how quickly we complete our clinical trials is dependent in part upon the rate at which we are able to engage clinical trial sites and, thereafter, the rate of enrollment of patients, and the rate we collect, clean, lock and analyze the clinical trial database. Patient enrollment is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the study, the existence of competitive clinical trials, and whether existing or new drugs are approved for the indication we are studying. We are aware that other companies are currently conducting or planning clinical trials that seek to enroll patients with the same disease that we are studying. If we experience delays in identifying and contracting with sites and/or in patient enrollment in our clinical trial programs, we may incur additional costs and delays in our development programs, and may not be able to complete our clinical trials in a cost-effective or timely manner or at all. In addition, conducting multi-national studies adds another level of complexity and risk. As a result, we may be subject to events affecting countries outside the United States.

27



Negative or inconclusive results from the clinical trials we conduct, or unanticipated adverse medical events could cause us to have to repeat or terminate the clinical trials. For example, in May 2012, we abandoned our development efforts and terminated our license for KRX-0401 (perifosine) following negative results from the Phase 3 trial for KRX-0401. We may also opt to change the delivery method, formulation or dosage which could affect efficacy results for the drug. Accordingly, we may not be able to complete our current or future clinical trials within an acceptable time frame, if at all.
Pre-clinical testing and clinical development are long, expensive and uncertain processes.
Pre-clinical testing and clinical development are long, expensive and uncertain processes. Satisfaction of regulatory requirements typically depends on the nature, complexity and novelty of the product. It requires the expenditure of substantial resources. Data obtained from pre-clinical and clinical tests can be interpreted in different ways, which could delay, limit or prevent regulatory approval. The FDA may pose additional questions or request further toxicological, drug-drug interaction, pre-clinical or clinical data or substantiation. Negative, inconclusive, or insufficient results or medical events during a pre-clinical or clinical trial could cause us to delay or terminate our development efforts. Furthermore, interim results of preclinical or clinical studies do not necessarily predict their final results, and acceptable results in early studies might not be obtained in later studies.
Drug candidates in the later stages of clinical development may fail to show the desired traits of safety and efficacy despite positive results in earlier clinical testing. The risk also remains that a clinical program conducted by one of our partners may raise efficacy or safety concerns that may prevent approval of the drug. In addition, qualitative, quantitative and statistical interpretation of any of the prior pre-clinical and clinical safety and efficacy data of our drug may be viewed as flawed by the FDA. In addition, there can be no assurance that safety and/or efficacy concerns from the prior data were not overlooked or misinterpreted by us or our consultants, which in subsequent, larger studies might appear and prevent approval of such drug candidate.
Clinical trials have a high risk of failure. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after achieving what appeared to be promising results in earlier trials. We experienced such a setback with our Phase 3 KRX-0401 (perifosine) trial results in April 2012, and we can provide no assurance that we will not experience such setbacks with ferric citrate or any other drug candidate we develop or acquire. If we experience delays in the testing or approval process for any drug we may commercialize or develop or if we need to perform more or larger clinical trials than originally planned, our financial results and the commercial prospects for our drug may be materially impaired. In addition, we have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approval. Accordingly, we may encounter unforeseen problems and delays in the approval process. Although we engage, from time to time, clinical research organizations, or CROs, with experience in conducting regulatory trials, errors in the conduct, monitoring, data capture and analysis, and/or auditing could potentially invalidate the results.
Because all of our proprietary technologies are licensed or sublicensed to us by third parties, termination of these license rights would prevent us from developing and further commercializing Auryxia.
We do not own our drug, Auryxia. We have licensed and sublicensed the rights, patent or otherwise, to Auryxia from a third party, Panion & BF Biotech, Inc., or Panion, who in turn licenses certain rights to Auryxia from one of the inventors of Auryxia. The license agreement with Panion requires us to meet development milestones and imposes development and commercialization due diligence requirements on us. In addition, under the agreement, we must pay royalties based on a mid-single digit percentage of net sales of product resulting from the licensed technologies (including Auryxia) and pay the patent filing, prosecution and maintenance costs related to the license. If we do not meet our obligations in a timely manner or if we otherwise breach the terms of our license agreement (including upon certain insolvency events), Panion could terminate the agreement, and we would lose the rights to Auryxia. In addition, if Panion breaches its agreement with the inventor from whom it licenses rights to Auryxia, Panion could lose its license, which could impair or delay our ability to develop and commercialize Auryxia. From time to time, we may have disagreements with our licensors or collaborators, or they and/or we may have disagreements with the original inventors, regarding the terms of our agreements or ownership of proprietary rights, which could lead to delays in the research, development and commercialization of our current drug and any future drug candidate, could require or result in litigation or arbitration, which would be time-consuming and expensive, or could lead to the termination of a license, or force us to negotiate a revised or new license agreement on terms less favorable than the original. In addition, in the event that the owners and/or licensors of the rights we license were to enter into bankruptcy or similar proceedings, we could potentially lose our rights to our drug or drug candidates or our rights could otherwise be adversely affected, which could prevent us from developing or commercializing our drugs. Finally, our rights to develop and commercialize Auryxia, whether ourselves or with third parties, are subject to and limited by the terms and conditions of our licenses to Auryxia and the licenses and sublicenses we grant to others.
Our reliance on third parties, such as CROs, may result in delays in completing, or a failure to complete, clinical trials if such CROs fail to perform under our agreements with them.

28



In the course of product development, we engage CROs and other vendors to conduct and manage clinical studies and to assist us in guiding our products through the FDA review and approval process. If the CROs or applicable vendors fail to perform their obligations under our agreements with them or fail to perform clinical trials in a satisfactory or timely manner, we may face significant delays in completing our clinical trials, submitting our regulatory filings, or approval, as well as the commercialization of one or more drug candidates. Furthermore, any loss or delay in obtaining contracts with such entities may also delay the completion of our clinical trials and the market approval of drug candidate(s).

Other risks related to our business
Any acquisitions we make may require a significant amount of our available cash, may dilute our stockholders and may not be scientifically or commercially successful.
As part of our business strategy, we may effect acquisitions to obtain additional businesses, products, technologies, capabilities and personnel. If we make one or more significant acquisitions in which the consideration includes cash, we may be required to use a substantial portion of our available cash. In addition, if we issue our equity securities as consideration in any acquisition, the ownership interests of our stockholders will be diluted.
Acquisitions involve a number of operational risks, including:
difficulty and expense of assimilating the operations, technology and personnel of the acquired business;
our inability to retain the management, key personnel and other employees of the acquired business;
our inability to maintain the acquired company’s relationship with key third parties, such as alliance partners;
exposure to legal claims for activities of the acquired business prior to the acquisition;
the diversion of our management’s attention from our core business; and
the potential impairment of goodwill and write-off of in-process research and development costs, adversely affecting our reported results of operations.
If we do not successfully integrate any acquisition into our business, our financial condition and operating results could be materially and negatively impacted.
Health care reform measures could adversely affect our business.
The business prospects and financial condition of pharmaceutical and biotechnology companies are affected by the efforts of governmental and third-party payers to contain or reduce the costs of health care. In the United States and in foreign jurisdictions there have been, and we expect that there will continue to be, a number of legislative and regulatory proposals aimed at changing the health care system, such as proposals relating to the pricing of healthcare products and services in the United States or internationally, the reimportation of drugs into the United States from other countries (where they are then sold at a lower price), and the amount of reimbursement available from governmental agencies or other third-party payers. For example, drug manufacturers are required to have a national rebate agreement with the Department of Health and Human Services, or HHS, in order to obtain state Medicaid coverage, which requires manufacturers to pay a rebate on drugs dispensed to Medicaid patients. On January 27, 2012, the Centers for Medicare and Medicaid Services, or CMS, issued a proposed regulation covering the calculation of Average Manufacturer Price, or AMP, which is the key variable in the calculation of these rebates.
Furthermore, in the United States, health care reform legislation titled the Patient Protection and Affordable Care Act, or PPACA, was signed into law in March 2010. The impact of this legislation on our business is inherently difficult to predict as many of the details regarding the implementation of this legislation have not been determined. In a decision issued on June 29, 2012, the United States Supreme Court upheld the majority of PPACA. The Court’s decision allows implementation of key provisions impacting drug and device manufacturers to go forward. This includes PPACA changes to the Medicare Part D Program (including closing the “donut hole”), Medicaid Drug Rebate Program (including the definition of AMP), and expansion of the 340B Drug Discount Program. The decision also allows the FDA and CMS to continue with implementation efforts, including related to the Biologics Price Competition and Innovation Act and the Physician Payments Sunshine Act, both of which were enacted as part of the PPACA. Regulations to implement PPACA could result in a decrease in our stock price or limit our ability to raise capital or to obtain strategic partnerships or licenses. Government-financed comparative efficacy research could also result in new practice guidelines, labeling or reimbursement policies that discourages use of our product.
For example, in July 2010, CMS released its final rule to implement a bundled prospective payment system for end-stage renal disease facilities as required by the Medicare Improvements for Patients and Providers Act, or MIPPA. The final rule

29



delayed the inclusion of oral medications without intravenous equivalents, such as phosphate binders, in the bundle until January 1, 2014; however, on January 3, 2013, the United States Congress passed legislation known as the American Taxpayer Relief Act of 2012, which, among other things, delayed by two years the implementation of oral-only end-stage renal disease related drugs, including phosphate binders, in the bundled ESRD prospective payment system, until January 1, 2016. In April 2014, the United States Congress passed legislation known as Protecting Access to Medicare Act of 2014, which, among other things, delays by eight years the implementation of oral-only ESRD related drugs, including phosphate binders, in the bundled ESRD prospective payment system, until January 1, 2025. If phosphate binders are included in the bundle beginning in 2025, or earlier, separate Medicare reimbursement will no longer be available for phosphate binders, as it is today under Medicare Part D. While it is too early to project the impact bundling may have on the phosphate binder industry, the impact could potentially cause dramatic price reductions for phosphate binders, which could significantly reduce the commercial potential of Auryxia.
On September 27, 2007, the Food and Drug Administration Amendments Act of 2007 was enacted, giving the FDA enhanced post-market authority, including the authority to require post-marketing studies and post-marketing clinical trials related to serious risks, labeling changes based on new safety information, and compliance with risk evaluation and mitigation strategies approved by the FDA. The FDA’s exercise of this authority may result in delays or increased costs during the period of product development, clinical trials and regulatory review and approval, which may also increase costs related to complying with new post-approval regulatory requirements, and increase potential FDA restrictions on the sale or distribution of approved products. On July 9, 2012, the Food and Drug Administration Safety and Innovation Act was enacted to, among other things, renew the drug user fee program, expand the FDA’s inspection records access and require manufacturers to establish appropriate oversight and controls over their suppliers and the supply chain, including raw material suppliers and contract manufacturers, as a part of cGMP compliance. On November 27, 2013, the Drug Quality and Security Act, which includes the Drug Supply Chain Security Act, was signed into law to, among other things, build an electronic, interoperable system to identify and trace certain prescription drugs as they are distributed in the United States. Requirements for the tracing of products through the pharmaceutical distribution supply chain took effect on January 1, 2015 for manufacturers and building internal systems to ensure compliance with this law will require dedication of resources. In addition, this law requires engaging in transactions only with authorized trading partners and could limit our pool of available trading partners.
We face product liability risks and may not be able to obtain adequate insurance.
The use of our drug commercially and in clinical trials exposes us to liability claims. In addition, the use of any other drug candidate we develop or acquire in clinical trials, the future sale of any other approved drug and the use of new technology will also expose us to liability claims. Although we are not aware of any historical or anticipated product liability claims against us, if we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to cease clinical trials of our drug product or limit commercialization of any approved product.
We have expanded our insurance coverage to include the commercial sale of Auryxia; however, insurance coverage is becoming increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost. We also may not be able to obtain additional insurance coverage that will be adequate to cover product liability risks that may arise. Regardless of merit or eventual outcome, product liability claims may result in:
decreased demand for a product;
injury to our reputation;
our inability to continue to develop a drug candidate;
withdrawal of clinical trial volunteers; and
loss of revenues.
Consequently, a product liability claim or product recall may result in losses that could be material to our business.
Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.
In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and that of our suppliers and business partners, as well as personally identifiable information of Auryxia patients, clinical trial participants and employees. We also have outsourced elements of our information technology structure, and as a result, we are managing independent vendor relationships with third parties who may or could have access to our confidential information.  Similarly, our business partners and other third-party providers possess certain of our sensitive data. The secure maintenance of this information is critical to our operations and business strategy. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions. We, our partners, vendors and other third-party providers could be susceptible to third-party attacks on our, and their, information security systems, which attacks are of ever increasing levels of sophistication and are

30



made by groups and individuals with a wide range of motives and expertise, including criminal groups. Any such breach could compromise our, and their, networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, disrupt our operations, and damage our reputation, any of which could adversely affect our business.

Risks related to our financial condition
Our existing capital resources may not be adequate to finance our operating cash requirements for the length of time that we have estimated.
We currently expect that our existing capital resources, future anticipated cash flows from product sales and the funds from future financings will be sufficient to execute our current business objectives. The actual amount of cash that we will need to operate our business is subject to many factors, including, but not limited to, the timing and expenditures associated with commercial activities related to Auryxia and the timing and magnitude of cash received from product sales, the timing and expenditures associated with the build-up of inventory and capacity expansion, and the timing, design and conduct of any further clinical trials for Auryxia. As a result of these factors, we will need to seek additional financing to provide the cash necessary to execute our current operations, including beyond commercializing Auryxia, and to develop and commercialize any drugs or drug candidates we may in-license or acquire.
Our forecast of the period of time through which our existing capital resources will be adequate to support our current operations is a forward-looking statement that involves risks and uncertainties. The actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control. These factors include, but are not limited to, the following:
our ability to successfully market Auryxia as a drug for adults with CKD on dialysis and for the treatment of iron deficiency anemia in adults with CKD, not on dialysis;
the timing and expenditures associated with commercial activities related to Auryxia and the timing and magnitude of cash received from product sales;
the timing and expenditures associated with the build-up of inventory and capacity expansion;
our ability to continue to supply Auryxia to the market without interruption;
our ability to continue to grow Auryxia product sales following the resupply of Auryxia to the market following the recent interruption in its supply;
the timing, design and conduct of, and results from, clinical trials that we may conduct;
the timing of expenses associated with manufacturing and product development of Auryxia and those proprietary drug candidates that may be in-licensed, partnered or acquired;
the timing of the in-licensing, partnering and acquisition of new product opportunities;
the timing and expenditures associated with commercial activities related to launching Fexeric in Europe, either by us or through a commercialization partner;
the progress of the development efforts of parties with whom we have entered, or may enter, into research and development agreements;
our ability to achieve our milestones under our licensing arrangement;
the timing and expenses associated with capital expenditures to expand our manufacturing capabilities;
the timing and expenses associated with building our own commercial infrastructure to manufacture, market and sell our drug and those that may be in-licensed, partnered or acquired; and
the costs involved in prosecuting and enforcing patent claims and other intellectual property rights, defending against post-grant proceedings initiated by third parties attempting to limit or cancel our intellectual property rights in the United States and elsewhere, such as U.S. inter partes review proceedings and/or European oppositions, or defending against claims of infringement initiated by third parties in respect of their intellectual property rights.
If our cash is insufficient to meet our future operating requirements, we will have to raise additional funds. If we are unable to obtain additional funds on terms favorable to us, or at all, we may be required to cease or reduce our operating

31



activities or sell or license to third parties some or all of our intellectual property. If we raise additional funds by selling additional shares of our capital stock, including pursuant to our Controlled Equity Offering SM Sales Agreement, or Sales Agreement, with Cantor Fitzgerald & Co., or Cantor Fitzgerald, the ownership interests of our stockholders will be diluted. If we need to raise additional funds through the sale or license of our intellectual property, we may be unable to do so on terms favorable to us, if at all.

Risks related to our intellectual property and third-party contracts
If we are unable to adequately protect our intellectual property, third parties may be able to use our intellectual property, which could adversely affect our ability to compete in the market.
Our commercial success will depend in part on our ability, and the ability of our licensors, to obtain and maintain patent protection on our drug product and technologies, and to successfully defend these patents against third-party challenges. We seek to protect our proprietary products and technology by filing patent applications in the United States and certain foreign jurisdictions. The process for obtaining patent protection is expensive and time consuming, and we may not be able to file and prosecute all necessary or desirable patent applications in a cost effective or timely manner. In addition, we may fail to identify patentable subject matter before it is too late to obtain patent protection. Further, license agreements with third parties may not allow us to control the preparation, filing and prosecution of patent applications, or the maintenance or enforcement of patents. Such third parties may decide not to enforce such patents or enforce such patents without our involvement. Thus, these patent applications and patents may not under these circumstances be prosecuted or enforced in a manner consistent with the best interests of the company.
Our pending patent applications may not issue as patents and may not issue in all countries in which we develop, manufacture or potentially sell our product(s) or in countries where others develop, manufacture and potentially sell products using our technologies. Moreover, our pending patent applications, if issued as patents, may not provide additional protection for our product.
The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in biotechnology patents has emerged to date. Changes in the patent laws or the interpretation of the patent laws in the United States and other jurisdictions may diminish the value of our patents or narrow the scope of our patent protection. Accordingly, the patents we own or license may not be sufficiently broad to prevent others from practicing our technologies or from developing competing products. Furthermore, others may independently develop similar or alternative drug products or technologies or design around our patented drug product and technologies which may have an adverse effect on our business. If our competitors prepare and file patent applications in the United States that claim technology also claimed by us, we may have to participate in interference or derivation proceedings in front of the U.S. Patent and Trademark Office, or USPTO, to determine priority of invention, which could result in substantial cost, even if the eventual outcome is favorable to us. Because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that any related patent may expire prior to, or remain in existence for only a short period following, commercialization, thus reducing any advantage of the patent. The patents we own or license may be challenged or invalidated or may fail to provide us with any competitive advantage. Since we have licensed or sublicensed many patents from third parties, we may not be able to enforce such licensed patents against third party infringers without the cooperation of the patent owner and the licensor, which may not be forthcoming. In addition, we may not be successful or timely in obtaining any patents for which we submit applications.
Additionally, the laws of foreign countries may not protect our intellectual property rights to the same extent as do the laws of the United States. For example, claims in a patent application directed to methods of treatment of the human body are not patentable or are restricted in many non-U.S. countries. Further, we may not pursue or obtain patent protection in all major markets. In addition, in jurisdictions outside the United States where we own or license patent rights, we may be unable to prevent unlicensed parties from selling or importing products or technologies derived elsewhere using our proprietary technology.
Generally, the first to file a patent application is entitled to the patent if all other requirements of patentability are met. However, prior to March 16, 2013, in the United States, the first to invent was entitled to the patent. Since publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all, we cannot know with certainty whether we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions. Moreover, the laws enacted by the Leahy-Smith America Invents Act of 2011, or the Act, which reformed certain patent laws in the United States, are still being interpreted and those laws introduce procedures that permit competitors to challenge our patents in the USPTO after grant, including inter partes review and post grant review. Similar laws exist outside of the United States. The laws of the European Patent Convention, for

32



example, provide for post-grant opposition procedures that permit competitors to challenge our patents at the European Patent Office. We currently have two issued European patents involved in such post-grant opposition proceedings.
We may become involved in addressing patentability objections based on third party submission of references, or we may become involved in defending our patent rights in oppositions, derivation proceedings, reexamination, inter partes review, post grant review, interference proceedings or other patent office proceedings or litigation, in the United States or elsewhere, challenging our patent rights or the patent rights of others. An adverse result in any such proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us.
The issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may be challenged on such a basis in the courts or patent offices in the United States and abroad. As a result of such challenges, we may lose exclusivity or freedom-to-operate, or patent claims may be narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to prevent third parties from using or commercializing similar or identical products, or limit the duration of the patent protection for our products.
In addition, patents protecting our product candidate might expire before or shortly after such candidate is commercialized. Thus, our patent portfolio may not provide sufficient rights to exclude others from commercializing products similar or identical to ours.
We also rely on trade secrets and know-how to protect our intellectual property where we believe patent protection is not appropriate or obtainable. Trade secrets are difficult to protect. While we require our employees, licensees, collaborators and consultants to enter into confidentiality agreements, this may not be sufficient to adequately protect our trade secrets or other proprietary information. In addition, we share ownership and publication rights to data relating to our drug product and technologies with our research collaborators and scientific advisors. If we cannot maintain the confidentiality of this information, our ability to receive patent protection or protect our trade secrets or other proprietary information will be at risk.
The intellectual property that we own or have licensed relating to our drug, Auryxia, is limited, which could adversely affect our ability to compete in the market and adversely affect the value of Auryxia.
The patent rights that we own or have licensed relating to Auryxia are limited in ways that may affect our ability to exclude third parties from competing against us. For example, a third party may design around our owned or licensed composition of matter patent claims or not market a product for methods of use covered by our owned or licensed patents.
Obtaining proof of direct infringement by a competitor for a method of use patent requires us to demonstrate that the competitors make and market a product for the patented use(s). Alternatively, we can prove that our competitors induce or contribute to others in engaging in direct infringement. Proving that a competitor contributes to, or induces, infringement of a patented method by another has additional proof requirements. For example, proving inducement of infringement requires proof of intent by the competitor. If we are required to defend ourselves against claims or to protect our own proprietary rights against others, it could result in substantial costs to us and the distraction of our management. An adverse ruling in any litigation or administrative proceeding could prevent us from marketing and selling Auryxia, increase the risk that a generic version of Auryxia could enter the market to compete with Auryxia, limit our development and commercialization of Auryxia, or otherwise harm our competitive position and result in additional significant costs. In addition, any successful claim of infringement asserted against us could subject us to monetary damages or injunction, which could prevent us from making or selling Auryxia. We also may be required to obtain licenses to use the relevant technology. Such licenses may not be available on commercially reasonable terms, if at all.
Moreover, physicians may prescribe a competitive identical product for indications other than the one for which the product has been approved, or “off-label” indications, that are covered by the applicable patents. Although such off-label prescriptions may directly infringe or contribute to or induce infringement of method of use patents, such infringement is difficult to prevent.
In addition, any limitations of our patent protection described above may adversely affect the value of our drug product and may inhibit our ability to obtain a corporate partner at terms acceptable to us, if at all.
In addition to patent protection, we may utilize, if granted by the FDA, pediatric exclusivity or other provisions of the FDCA such as new chemical entity exclusivity, or NCE, or new formulation exclusivity, to provide market exclusivity for a drug candidate.
In the United States, the FDA has the authority to grant additional data protection for approved drugs where the sponsor conducts specified testing in pediatric or adolescent populations. If granted, this pediatric exclusivity may provide an additional six months which are added to the term of data protection as well as to the term of a relevant patent, to the extent these protections have not already expired.

33



The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of a new drug application, or NDA, for a NCE. A drug is an NCE if the FDA has not previously approved any other new drug containing the same active moiety, which consists of the molecule(s) or ion(s) responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an ANDA or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application (for example, for new indications, dosages, or strengths of an existing drug). This three-year exclusivity covers only the conditions associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Five-year and three-year exclusivity will not delay the submission or tentative approval of a full ANDA; however, an applicant submitting a full ANDA would be required to conduct sufficient studies to demonstrate that their generic product is bioequivalent to Auryxia.
We cannot assure that Auryxia or any drug candidates we may acquire or in-license, will obtain such pediatric exclusivity, NCE exclusivity or any other market exclusivity in the United States, EU or any other territory, or that we will be the first to receive the respective regulatory approval for such drugs so as to be eligible for any market exclusivity protection. We also cannot assure that Auryxia or any drug candidates we may acquire or in-license will obtain patent term extension.
Litigation or third-party claims could require us to spend substantial time and money defending such claims and adversely affect our ability to develop and commercialize our product.
We may be forced to initiate litigation to enforce our contractual and intellectual property rights, or we may be sued by third parties asserting claims based on contract, tort or intellectual property infringement. In addition, third parties may have or may obtain patents in the future and claim that Auryxia or any other technologies infringe their patents. If we are required to defend against suits brought by third parties, or if we sue third parties to protect our rights, we may be required to pay substantial litigation costs, and our management’s attention may be diverted from operating our business. In addition, any legal action against our licensor or us that seeks damages or an injunction of our commercial activities relating to Auryxia or other technologies could subject us to monetary liability, a temporary or permanent injunction preventing the development, marketing and sale of Auryxia or such technologies, and/or require our licensor or us to obtain a license to continue to use Auryxia or other technologies. We cannot predict whether our licensor or we would prevail in any of these types of actions or that any required license would be made available on commercially acceptable terms, if at all.
We may be subject to claims by third parties asserting that we or our employees have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.
A number of our employees were previously employed at universities, or pharmaceutical or biotechnology companies, some of which may be a competitor or potential competitor. We try to ensure that our employees do not use the proprietary information or know-how of third parties in their work for us. Nonetheless, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee's former employer. As a result, litigation may be necessary to defend against these claims.
In addition, although we typically require our employees and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that we regard as our own. Such assignment agreements may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.
In the event that we fail in prosecuting or defending any such claims, we may need to pay monetary damages as well as lose valuable intellectual property rights or personnel. However, regardless of the success in prosecuting or defending against such claims, such litigation may result in substantial costs and distract management.

Risks related to our common stock
The Baupost Group, L.L.C, or Baupost, our largest stockholder, may have significant influence over our company and may cause us to take actions that may not be, or refrain from taking actions that may be, in our best interest or the best interest of our other stockholders.
As of September 30, 2017, Baupost beneficially owns approximately 22% of our issued and outstanding common stock. If Baupost converts all of the convertible notes it holds into shares of our common stock, Baupost would beneficially

34



own approximately 39% of our issued and outstanding common stock. Baupost, through its equity interests, may have significant influence over matters submitted to our stockholders for approval and other corporate actions, such as:
election of directors;
timing and manner in which we raise additional funds;
timing and manner of dividend distributions;
approval of contracts between us and Baupost or its respective affiliates, which could involve conflicts of interest;
open market purchase programs or other purchases of our common shares;
delay, defer or prevent a change in who controls us;
discourage bids for our shares at a premium over the market price; and
adversely affect the market price of our common shares.

Moreover, because large stockholders have potential power to direct or influence our corporate actions, we may be required to engage in transactions that may not be agreeable to our other stockholders or that may not be in the best interest of our other stockholders. In addition, Baupost has the right to appoint a director to our Board and also has the right to appoint an observer to our Board.
Future sales or other issuances of our common stock could depress the market for our common stock.
Sales of a substantial number of shares of our common stock, or the perception by the market that those sales could occur, could cause the market price of our common stock to decline or make it more difficult for us to raise funds through the sale of equity in the future.
In November 2016, we filed a registration statement on Form S-3 (No. 333-214513), which the SEC declared effective on December 6, 2016, which registered the issuance from time to time of up to $250 million of our securities. At that time, we also entered into the Sales Agreement with Cantor Fitzgerald, pursuant to which we were initially able to offer and sell, from time to time, through Cantor Fitzgerald, shares of our common stock having an aggregate offering price of up to $75.0 million. During the six months ended June 30, 2017, we sold 11,574,320 shares under the Sales Agreement for aggregate net proceeds of $73.1 million. The sales during the six months ended June 30, 2017 amounted to the initial $75.0 million issuable pursuant to the Sales Agreement. In July 2017, we filed a new prospectus supplement with the SEC relating to the Sales Agreement under which we may offer and sell, from time to time, through Cantor Fitzgerald, shares of our common stock having an additional aggregate offering price of up to $75.0 million. During the three months ended September 30, 2017, we sold 362,854 shares under the Sales Agreement for aggregate net proceeds of $2.6 million. The initial $75.0 million of common stock issued pursuant to the Sales Agreement and the additional $75.0 million of common stock issuable pursuant to the Sales Agreement are included as part of the $250 million registered on the registration statement referred to above.
In October 2015, we raised $125 million through the private placement of Convertible Senior Notes, due 2020, with funds managed by Baupost. The zero-coupon notes will mature in October 2020 unless converted into shares of our common stock in accordance with their terms prior to such date. Keryx does not have the right to redeem the notes prior to maturity. The conversion price of the notes is equal to the $3.74 per share closing price of our common stock on the day prior to the issuance of the Notes in October, 2015, subject to certain adjustments under the terms of the notes.
On January 21, 2015, we announced the pricing of an underwritten public offering in which we sold 10,541,667 shares of our common stock at a price of $12.00 per share for gross proceeds of approximately $126.5 million. Net proceeds from this offering were approximately $118.3 million, net of underwriting discounts and offering expenses of approximately $8.2 million. The shares were sold under registration statements (Nos. 333-201605 and 333-201639) on Form S-3 and Form S-3MEF, respectively, filed by us with the SEC.
We will need to seek additional financings to provide cash necessary to execute our current operations, including, but not limited to, beyond commercializing Auryxia, and to develop and commercialize any drugs or drug candidates we may in-license or acquire. Future issuances of common stock could depress the market for our common stock.
If we make one or more significant acquisitions in which the consideration includes stock or other securities, our stockholders’ holdings may be significantly diluted. In addition, stockholders’ holdings may also be diluted if we enter into arrangements with third parties permitting us to issue shares of common stock in lieu of certain cash payments upon the achievement of milestones.

35



Our stock price can be volatile, which increases the risk of litigation, and may result in a significant decline in the value of your investment.
The trading price of our common stock is likely to be highly volatile and subject to wide fluctuations in price in response to various factors, many of which are beyond our control. These factors include:
actual or anticipated variations in quarterly or annual operating results, including, in particular with respect to net U.S. Auryxia product sales;
announcements of technological innovations by us or our competitors;
introductions or announcements of new products by us or our competitors;
announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments involving us or our competitors;
changes in financial estimates by securities analysts;
developments relating to the marketing, safety and efficacy of our drug product, and regulatory filing and approvals for us or our competitors;
expectations regarding our financial condition;
expiration or termination of licenses, research contracts or other collaboration agreements;
expectations or investor speculation regarding the strength of our intellectual property position, or the availability of other forms of regulatory exclusivity;
conditions or trends in the regulatory climate and the biotechnology and pharmaceutical industries;
changes in the market valuations of similar companies;
negative comments and sentiment in the media; and
additions or departures of key personnel.
In addition, equity markets in general, and the market for biotechnology and life sciences companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies traded in those markets. These broad market and industry factors may materially affect the market price of our common stock, regardless of our development and operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation has often been instituted against that company. For example, following our August 1, 2016 announcement of the supply interruption of Auryxia, four purported class action lawsuits were filed against us and certain of our current and former executive officers alleging false and/or misleading statements concerning the company and its business operations and future prospects, and two stockholder derivative complaints were filed against certain of our current and former executive officers and members of our board of directors. These litigations and any other litigation instituted against us could cause us to incur substantial costs to defend such claims and divert management’s attention and resources, which could seriously harm our business.
Certain anti-takeover provisions in our charter documents and Delaware law could make a third-party acquisition of us difficult. This could limit the price investors might be willing to pay in the future for our common stock.
Provisions in our amended and restated certificate of incorporation and bylaws could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, or control us. These factors could limit the price that certain investors might be willing to pay in the future for shares of our common stock. Our amended and restated bylaws prohibit our stockholders from acting by written consent and eliminate the right of stockholders to call a special meeting of stockholders, which could make it more difficult for stockholders to effect certain corporate actions. Any of these provisions could also have the effect of delaying or preventing a change in control.

ARTICLE 1. DEFINITIONS
As used in this Agreement, the following terms, whether used in the singular or the plural, shall have the following meanings:
1.1      “Affiliate” means any corporation or non-corporate business entity, which controls, is controlled by, or is under common control with a party to this Agreement. A corporation or non-corporate business entity shall be regarded as in control of another corporation if it owns or directly or indirectly controls at least fifty-one percent (51%) of the voting stock of the other corporation, or (i) in the absence of the ownership of at least fifty-one percent (51%) of the voting stock of a corporation, or (ii) in the case of a non-corporate business entity, if it possesses, directly or indirectly, the power to direct or cause the direction of the management and policies of the corporation or non-corporate business entity, as applicable. Notwithstanding the foregoing, the Government of Japan and other entities controlled by the Government of Japan (other than through Japan Tobacco Inc.) are not considered Affiliates of Sublicensee.
1.2      “Combination Product” means a Product containing one or more therapeutically active ingredients in addition to the Compound.
1.3      “Compound” means ferric citrate: FeC 6 H 5 O 7 • xH 2 O
1.4      Intentionally omitted .
1.5      Intentionally omitted .
1.6      “Follow-on Product” means products, other than the Product, which contain ferric ion as an active pharmaceutical ingredient for use, either alone, or in combination with one or more therapeutically active ingredients.
1.7      “Improvements” means any and all improvements, materials, technical data and information whether patented or unpatented, including but not limited to any changes to, or new therapeutic applications for, the Compound, the Product or in the Sublicensor Know-How or Sublicensee Know-How including, but not limited to any analogues, or derivatives of the Compound, and changes in the manufacturing process for the Compound or the Product which are conceived or reduced to practice during the term of this Agreement.
1.8      “Indication” means any therapeutic application for a Product that is covered by the Patent Rights.
1.9      “Initiation” means the administration of the first dose to the first patient in a clinical trial.
1.10      “Net Sales” with respect to any Product means the gross sales (i.e. gross invoice prices) of such Product billed by Sublicensee and its sublicensees, if any, to Third Party customers on all sales of a Product, and exclusive of inter-company transfer or sales, less the reasonable and customary deductions from such gross sales, including:
(a)    actual credited allowances to such Third Party customers for spoiled, damaged, outdated and returned Product and for retroactive price reductions,
(b)    the amounts of trade, cash discounts and rebates, to the extent such discounts and rebates were not deducted by Sublicensee at the time of invoice in order to arrive at the gross invoice prices,
(c)    all transportation, handling charges and freight insurance, sales taxes, excise taxes, use taxes or import/export duties paid, and
(d)    all other reasonable and customary allowances and adjustments actually credited to customers whether during the specific royalty period or not.
In the event that the Product(s) is sold as part of a Combination Product, the Net Sales of the Product(s), for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of Combination Product (as defined in the standard Net Sales definition) by the fraction, A / (A+B) where A is the weighted average sale price of the Product(s) when sold separately in finished form (as defined below), and B is the weighted average sale price of the other product(s) sold in the Sublicense Territory separately in finished form.
In the event that the weighted average sale price of the Product(s) can be determined but the weighted average sale price of the other product(s) in the Sublicense Territory cannot be determined, Net Sales for purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the fraction A / C where A is the weighted average sale price of the Product(s) when sold separately in finished form and C is the weighted average selling price of the Combination Product.
In the event that the weighted average sale price of the other product(s) in the Sublicense Territory can be determined but the weighted average sale price of the Product cannot be determined, Net Sales for purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the following formula:  1 – (B/C)  where B is the weighted average sale price of the other product(s) when sold separately in finished form and C is the weighted average selling price of the Combination Product.
In the event that the weighted sale price of both the Product(s) and the other product(s) in the Combination Product in the Sublicense Territory cannot be determined, the Parties will attempt to agree on an appropriate weighted average sale price of both the Product(s) and the other product(s) in the Combination Product, and lacking such agreement the Net Sales of the Product(s) shall be deemed equal to fifty percent (50%) of the Net Sales of the Combination Product.
By way of example, the parties assume a Combination product “C” consisting of the Product “A” and the other product “B.”  When the weighted average sale prices in the Sublicense Territory of A, B and C are 50, 40 and 90, respectively, the parties agree that the fraction to be used for Net Sales calculation for determining royalty payments shall become as follows:
i)    in case the “50” and “40” are known, 50/(50+40), i.e., 5/9;
ii)    in case the “40” is unknown but “90” is known, 50/90, i.e., 5/9;
iii)    in case the “50” is unknown but “90” is known, 1-40/90, i.e., 5/9; and
iv)    in case none of those is known, 1/2 unless otherwise agreed between the parties.
The weighted average sale price for a Product, other product(s), or Combination Product shall be calculated once each calendar year and such price shall be used during all applicable royalty reporting periods for the entire calendar year. When determining the weighted average sale price of a Product, other product(s), or Combination Product, the weighted average sale price shall be calculated by dividing the sales dollars (translated into U.S. Dollars) by the daily dose units of active ingredient sold during the twelve (12) months (or the number of months sold in a partial calendar year) for the respective Product(s), other product(s), or Combination Product. In the initial calendar year, a forecasted weighted average sale price will be used for Product(s), other product(s), or Combination Product. Any over or under payment due to a difference between forecasted and actual weighted average sale prices will be paid or credited in the first royalty payment of the following calendar year.
The Parties acknowledge that the foregoing determination for Net Sales of Combination Products may not be the same as the determination for Net Sales of Combination Products to be agreed upon between Sublicensor and Panion in accordance with the Panion License Agreement. Sublicensor agrees to use its commercially reasonable efforts to obtain Panion’s agreement to adopt the terms of this Section 1.10 to calculate Net Sales of Combination Products and will keep Sublicensee informed of ongoing negotiations concerning the provisions for Combination Products with Panion. In the event Sublicensor and Panion agree upon a different determination, Sublicensor shall immediately seek Sublicensee’s consent to amend this Section 1.10 to match such determination, which consent shall not be unreasonably withheld or delayed.
The sale of a Product solely for the research or clinical testing of such Product shall be excluded from the computation of Net Sales of such Product, provided that Sublicensee’s sale of the Product was at cost, and such Product was used for research or clinical testing.
1.11      “Patent Rights” means the patents and patent applications set forth in Exhibit 1 , all other patents and patent applications that are directed to the Compound or its manufacture or use and in which Sublicensor holds rights, including, without limitation, those patents and patent applications that are directed to Sublicensor’s interest in Improvements, and any and all patents in which Sublicensor holds rights and that may issue from any of the foregoing patent applications, including any and all divisions, continuations, continuations-in-part, extensions, substitutions, renewals, registrations, supplementary protection certificates, revalidations, reissues or additions of or to any of the aforesaid patents and patent applications, and any additional patents or patent applications to which Sublicensor acquires rights, including rights to license, during the term of this Agreement which pertain in any way to the Compound or the Product or their manufacture or use.

In case Sublicensee disagrees with such belief by Sublicensor, and the JSC, JDT or Other Committee fails to reach unanimous agreement on such a matter and that disagreement cannot be resolved within a period of fifteen (15) business days following the meeting of the JSC, JDT or Other Committee, the matter shall be referred to the Chief Executive Officer of Keryx and to the President of the JT Pharmaceutical Division for discussion and, if not resolved in such manner, shall be subject to Arbitration pursuant to Article 19.
ARTICLE 4.      LICENSE FEE; MILESTONE PAYMENTS
4.1      Intentionally omitted.
4.2      Milestone Payments . Sublicensee will pay to Sublicensor non-refundable, one-time milestone payments as follows:

(d)      Within thirty (30) days following a first marketing approval by MHLW for a Product in the Sublicense Territory: ten million dollars ($10,000,000).
For the purpose of this Agreement, a Phase II clinical trial shall mean that portion of the Regulatory Authority submission and approval process which provides for the initial trials of Product on a limited number of patients for the purposes of determining dose and evaluating safety and efficacy in the proposed therapeutic indication and a principal purpose of which is to demonstrate a proof of concept, and a Phase III clinical trial shall mean that portion of the Regulatory Authority submission and approval process which provides for the expanded trials of Product on a large number of patients for the purposes of evaluation of the overall benefit-risk relationship and long-term safety of the proposed therapeutic indication.
4.3      Sales Milestone Payments . Sublicensee will pay to Sublicensor the following non-refundable, one-time milestone payments as follows:
(a)      Within sixty (60) days following attainment of annual Net Sales in Japan equal to******;
(b)      Within sixty (60) days following attainment of annual Net Sales in Japan equal to******;
(c)      Within sixty (60) days following attainment of annual Net Sales in Japan equal to******.
For purposes of this Section 4.3, annual Net Sales shall be calculated on a calendar year basis. Nothing herein shall preclude multiple milestone payments from being paid in a given 12-month period if multiple milestones have been reached.
4.4      Limitations . It is understood and agreed that Sublicensee shall pay the milestone payments set forth in Sections 4.2 and 4.3 only with respect to the first Indication for which a Product achieves a particular milestone event, and regardless of the number of Products which achieve a particular milestone event and regardless of the number of times which a particular milestone event is achieved.
4.5      Payment Method . All payments of license fees and milestones under this Article 4 shall be made by wire transfer in the United States currency to a designated bank account of Sublicensor.
ARTICLE 5.      ROYALTIES
5.1      Royalties . In consideration of the sublicense rights granted to Sublicensee hereunder, for each Product where the manufacture, use or sale of such Product would but for the license granted hereunder, infringe a Valid Claim, Sublicensee shall pay to Sublicensor a royalty on their respective Net Sales, as follows:
(a)      a royalty of ****** of annual Net Sales equal to or less ******;
(b)      a royalty of ****** of annual Net Sales between ******;
(c)      a royalty of ****** of annual Net Sales in excess of ******.
For purposes of this Section 5.1, royalties shall be calculated based on total Net Sales in any given calendar year.  By way of example, if in a given calendar year Net Sales were forty (40) billion Japanese Yen, then the amount of royalty owed for that year would be ****** (calculated as the sum of ****** x ****** plus ****** x ****** plus ****** x ******). Notwithstanding the foregoing, in the event (i) the Panion License Agreement expires before the termination or expiration of this Agreement and Sublicensor is no longer required to pay royalties to Panion under the Panion License Agreement, the applicable royalty percentage to be paid by Sublicensee to Sublicensor under clauses (a), (b) and (c) of this Section 5.1 shall be reduced to ******, ****** and ******, respectively, or (ii) subject to Section 16.3, the Panion License Agreement is terminated before the termination or expiration of this Agreement, the royalties and other amounts to be paid by Sublicensee to Sublicensor shall be reduced by all royalties and other amounts payable directly by Sublicensee to Panion.
5.2      Accrual of Royalties . No royalty shall be payable on a Product made, sold, or used for research or clinical testing purposes or distributed as samples, provided such samples are sold by Sublicensee at cost. No multiple royalty shall be payable because the manufacture, use, or sale of a Product is covered by more than one Valid Claim.
5.3      Royalty Withheld due to Invalid Claims . In the event that all applicable claims of a patent included within the Patent Rights under which Sublicensee is paying a royalty according to Section 5.1 shall be held invalid or unenforceable by a court of competent jurisdiction in the Sublicense Territory, Sublicensee may withhold payments of royalties which would otherwise have been due on Net Sales in the Sublicense Territory by reason of Sections 4.3 and 5.1 until such judgment shall be finally reviewed by an unappealed or unappealable decree of a higher court of competent jurisdiction in the Sublicense Territory. The Sublicensee shall promptly repay Sublicensor any withheld royalty payments upon a final adjudication that the applicable claims of a patent included within the Patent Rights under which Sublicensee is paying a royalty under Section 5.1 are valid and enforceable. For clarification, the aforementioned withheld royalty shall not bear any interest thereon.
5.4      Compulsory Licenses .

Recognizing that the embodiments described above may be useful or necessary to Sublicensor in connection with its continued operation of its business, and that a Third Party may also have a right of access to such embodiment under Section 365(n) of the Bankruptcy Code or applicable non-bankruptcy law, where there is a fixed or limited quantity of any tangible item of such embodiment described above, Sublicensee shall be entitled to a pro rata portion thereof.
