1. The Company and Basis of Presentation

The Company is the Lipid Management Company, a late-stage pharmaceutical company focused on developing and commercializing complementary, cost-effective, convenient, once-daily, oral therapies for the treatment of patients with elevated low density lipoprotein cholesterol ("LDL-C"). Through scientific and clinical excellence, and a deep understanding of cholesterol biology, the experienced Lipid Management Team at Esperion is committed to developing new LDL-C lowering therapies that will make a substantial impact on reducing global cardiovascular disease ("CVD"); the leading cause of death around the world. Bempedoic acid and the bempedoic acid / ezetimibe combination tablet are targeted therapies that are being developed to significantly lower elevated LDL-C levels in patients with hypercholesterolemia, including patients inadequately treated with current lipid-modifying therapies.

On February 20, 2019, the Company submitted the new drug application (“NDA”) for bempedoic acid and on February 26, 2019, the Company submitted the NDA for the bempedoic acid / ezetimibe combination tablet to the Food and Drug Administration (“FDA”) for LDL-C lowering indications. On May 5, 2019, the Company announced that the FDA accepted the NDAs for bempedoic acid and the bempedoic acid / ezetimibe combination tablet for filing and regulatory review. The Prescription Drug User Fee Act (“PDUFA”) goal date for completion of the bempedoic acid NDA review is set for February 21, 2020, and the PDUFA goal date for completion of the bempedoic acid / ezetimibe combination tablet NDA review is set for February 26, 2020. These dates are consistent with the Company’s expectations and reflect the standard review period. The FDA has communicated that there is no current plan to hold an advisory committee meeting to discuss the applications. On February 11, 2019, the Company submitted the Marketing Authorization Applications (“MAAs”) for bempedoic acid and the bempedoic acid / ezetimibe combination tablet to the European Medicines Agency (“EMA”). On February 28, 2019, the EMA completed formal validation of the MAAs for bempedoic acid and the bempedoic acid / ezetimibe combination tablet for LDL-C lowering indications.

The Company is conducting a global cardiovascular outcomes trial ("CVOT")-known as Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes, for bempedoic acid in 12,604 patients with hypercholesterolemia and high CVD risk and who can be considered statin averse. The Company initiated the CLEAR Outcomes CVOT in December 2016 and expects the study to be fully enrolled in the third quarter of 2019. The Company intends to use positive results from this CVOT to support submissions for a CV risk reduction indication in the U.S. and Europe by 2022.

The Company's primary activities since incorporation have been conducting research and development activities, including nonclinical, preclinical and clinical testing, performing business and financial planning, recruiting personnel, and raising capital. Accordingly, the Company has not commenced principal operations and is subject to risks and uncertainties which include the need to research, develop, and clinically test potential therapeutic products; obtain regulatory approvals for its products and commercialize them, if approved; expand its management and scientific staff; and finance its operations with an ultimate goal of achieving profitable operations.

The Company has sustained annual operating losses since inception and expects such losses to continue over the foreseeable future. While management believes current cash resources and future cash received from the Company's collaboration agreement with Daiichi Sankyo Europe GmbH ("DSE"), entered into on January 2, 2019, and from the Revenue Interest Purchase Agreement (“RIPA”) with Eiger III SA LLC (“Oberland”), an affiliate of Oberland Capital LLC, and the Purchasers named therein, entered into on June 26, 2019, will fund operations for the foreseeable future, management may continue to fund operations and advance the development of the Company's product candidates through a combination of collaborations with third parties, strategic alliances, licensing arrangements, permitted debt financings, permitted royalty-based financings, and private and public and equity offerings or through other sources.

If adequate funds are not available, the Company may not be able to continue the development of its current or future product candidates, or to commercialize its current or future product candidates, if approved.

Table of Contents

Basis of Presentation

The accompanying condensed financial statements are unaudited and were prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“GAAP”). In the opinion of management, the Company has made all adjustments, which include only normal recurring adjustments necessary for a fair presentation of the Company’s financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted. These condensed interim financial statements should be read in conjunction with the audited financial statements as of and for the year ended December 31, 2018, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. The results of operations for the interim periods are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in accordance with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, expenses and related disclosures. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company invests its excess cash in bank deposits, money market accounts, and short-term investments. The Company considers all highly liquid investments with an original maturity of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents are reported at fair value.

Restricted Cash

Restricted cash consists of legally restricted amounts held by financial institutions pursuant to contractual arrangements.

Investments

Investments are considered to be available-for-sale and are carried at fair value. Unrealized gains and losses, if any, are reported as a separate component of stockholders’ equity. The cost of investments classified as available-for-sale are adjusted for the amortization of premiums and accretion of discounts to maturity and recorded in other income, net. Realized gains and losses, if any, are determined using the specific identification method and recorded in other income, net. Investments with original maturities beyond 90 days at the date of purchase and which mature at, or less than twelve months from, the balance sheet date are classified as current. Investments with a maturity beyond twelve months from the balance sheet date are classified as long-term.

Concentration of Credit Risk

Cash, cash equivalents, and marketable securities consist of financial instruments that potentially subject the Company to concentrations of credit risk. The Company has established guidelines for investment of its excess cash and believes the guidelines maintain safety and liquidity through diversification of counterparties and maturities.

Segment Information

The Company views its operations and manages its business in one operating segment, which is the business of researching, developing and commercializing therapies for the treatment of patients with elevated LDL-C.

Table of Contents

Fair Value of Financial Instruments

The Company’s cash, cash equivalents, restricted cash and investments are carried at fair value. Financial instruments, including other prepaid and current assets, accounts payable and accrued liabilities are carried at cost, which approximates fair value. Debt is carried at amortized cost, which approximates fair value.

Property and Equipment, Net

Property and equipment are recorded at cost, less accumulated depreciation. Depreciation is provided using the straight-line method over the estimated useful lives of the respective assets, generally three to ten years. Leasehold improvements are amortized over the lesser of the lease term or the estimated useful lives of the related assets.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. The impairment loss, if recognized, would be based on the excess of the carrying value of the impaired asset over its respective fair value. No impairment losses have been recorded through June 30, 2019.

Leases

The Company reviews all arrangements to determine if the contract contains a lease or an embedded lease using the criteria in Accounting Standards Codification (“ASC”) 842. If a lease is identified, the Company reviews the consideration in the contract and separates the lease components from the nonlease components. In addition, the Company reviews the classification of the lease between operating and finance leases. According to ASC 842, lessees should discount lease payments at the lease commencement date using the rate implicit in the lease. If the rate implicit in the lease is not readily determinable, a lessee must use its incremental borrowing rate for purposes of classifying the lease and measuring the right-of-use asset and liability. To the extent the rate is not implicit in the lease, the Company uses the incremental borrowing rate it would have to pay to borrow on a collateralized basis over a similar term in an amount equal to the lease payments in a similar economic environment.

Revenue Interest Liability

The revenue interest liability is presented net of deferred financing costs on the condensed balance sheets. The Company imputes non-cash interest expense associated with this liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. The interest rate on the liability may vary during the term of the agreement depending on a number of factors, including the level of forecasted sales. The Company evaluates the interest rate quarterly based on its current sales forecasts utilizing the prospective method.

Revenue Recognition

a.	Collaboration Revenue

The Company has entered into an agreement related to its activities to develop, manufacture, and commercialize its product candidates. The Company earns collaboration revenue in connection with a collaboration agreement to develop and/or commercialize product candidates where the Company deems the collaborator to be the customer. The Company has adopted ASC 606, Revenue from Contracts with Customers, and under the terms of the standard, revenue is measured as the amount of consideration expected to be entitled to in exchange for transferring promised goods or providing services to a customer. Revenue is recognized when (or as) the Company satisfies performance obligations under the terms of a contract. Depending on the terms of the arrangement, the Company may defer the recognition of all or a portion of the consideration received as the performance obligations are satisfied.

Table of Contents

The collaboration agreement may require the Company to deliver various rights, services, and/or goods across the entire life cycle of a product or product candidate. In the agreement involving multiple goods or services promised to be transferred to a customer, the Company must assess, at the inception of the contract, whether each promise represents a separate performance obligation (i.e., is "distinct"), or whether such promises should be combined as a single performance obligation.

The terms of the agreement typically include consideration to be provided to the Company in the form of non-refundable up-front payments, development milestones, sales milestones, and royalties on sales of products within a respective territory.

At the inception of the contract, the transaction price reflects the amount of consideration the Company expects to be entitled to in exchange for transferring promised goods or services to its customer. In the arrangement where the Company satisfies performance obligation(s) during the regulatory phase over time, the Company recognizes collaboration revenue typically using an input method on the basis of regulatory costs incurred relative to the total expected cost which determines the extent of progress toward completion. The Company reviews the estimate of the transaction price and the total expected cost each period, and makes revisions to such estimates as necessary.

Under the Company's collaboration agreement, product sales and cost of sales may be recorded by the Company's collaborators as they are deemed to be the principal in the transaction. The Company receives royalties from the commercialization of such products, and records its share of the variable consideration, representing a percentage of net product sales, as collaboration revenue in the period in which such underlying sales occur and costs are incurred by the collaborator. The collaborator will provide the Company with estimates of its royalties for such quarter; these estimates are reconciled to actual results in the subsequent quarter, and the royalty is adjusted accordingly, as necessary.

Please refer to the discussion in Note 3 “Collaborations with Third Parties” for further discussion of the accounting related to the collaboration agreement.

Research and Development

Research and development expenses consist of costs incurred to further the Company's research and development activities and include salaries and related benefits, costs associated with clinical activities, nonclinical activities, regulatory activities, manufacturing activities to support clinical activities and commercial product manufacturing supply as the Company approaches anticipated approval, research-related overhead expenses and fees paid to external service providers that conduct certain research and development, clinical, and manufacturing activities on behalf of the Company. Research and development costs are expensed as incurred.

Accrued Clinical Development Costs

Outside research costs are a component of research and development expense. These expenses include fees paid to clinical research organizations and other service providers that conduct certain clinical and product development activities on behalf of the Company. Depending upon the timing of payments to the service providers, the Company recognizes prepaid expenses or accrued expenses related to these costs. These accrued or prepaid expenses are based on management's estimates of the work performed under service agreements, milestones achieved and experience with similar contracts. The Company monitors each of these factors and adjusts estimates accordingly.

Income Taxes

The Company utilizes the liability method of accounting for income taxes as required by ASC 740, Income Taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and the tax basis of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company has incurred annual operating losses since inception. Accordingly, it is not more likely than not that the Company will realize a tax benefit from its deferred tax assets and as such, it has recorded a full valuation allowance.

Table of Contents

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with the provisions of ASC 718, Compensation-Stock Compensation. Accordingly, compensation costs related to equity instruments granted are recognized over the requisite service periods of the awards on a straight-line basis at the grant-date fair value calculated using a Black-Scholes option-pricing model. The Company accounts for forfeitures as they occur. Expense is recognized during the period the related services are rendered.

Recent Accounting Pronouncements

In November 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-08, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under ASC 606 when the collaborative arrangement participant is a customer in the context of a unit of account. The standard is effective for public companies for fiscal years beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted, included in any interim period, provided an entity has already adopted ASC 606 or does so concurrently with the adoption of this guidance. The Company early adopted this guidance as of January 1, 2019, and implemented the new guidance in its consideration of the accounting for the DSE collaboration signed on January 2, 2019. Refer to Note 3 “Collaborations with Third Parties” and the Collaboration Revenue accounting policy above for further information.

In February 2016, the FASB issued ASU 2016-02, which was amended by subsequent updates (collectively the “lease standard” or “ASC 842”), and is intended to improve financial reporting about leasing transactions. The updated guidance requires a lessee to recognize assets and liabilities for leases with lease terms of more than twelve months. The Company adopted the standard on January 1, 2019 using the modified retrospective method. Results for the reporting period beginning after December 31, 2018 have been presented in accordance with the standard, while results for prior periods have not been adjusted. The Company recognized $1.0 million and $1.0 million of operating lease assets and operating lease liabilities, respectively, on the Company’s balance sheets as of January 1, 2019, primarily related to the lease agreement for the Company’s principal executive office. Refer to Note 9 “Leases” for more information on the Company’s leases.

There have been no other material changes to the significant accounting policies previously disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

On January 2, 2019, the Company entered into a license and collaboration agreement with DSE. Pursuant to the agreement, the Company granted DSE exclusive commercialization rights to bempedoic acid and the bempedoic acid / ezetimibe combination tablet in the European Economic Area and Switzerland (“DSE Territory”). DSE will be responsible for commercialization in the DSE Territory. The Company remains responsible for clinical development, regulatory and manufacturing activities for the licensed products globally, including in the DSE Territory.

Pursuant to the agreement, the consideration consists of a $150.0 million upfront cash payment as well as $150.0 million cash payment to the Company upon first commercial sales in the DSE Territory. The Company is also eligible to receive a substantial additional regulatory milestone payment upon the grant of the marketing authorization in the European Union for the CV risk reduction label, depending on the range of relative risk reduction in the CLEAR Outcomes study. In addition, the Company is eligible to receive additional sales milestone payments related to total net sales achievements for DSE in the DSE Territory. Finally, the Company will receive tiered fifteen percent (15%) to twenty-five percent (25%) royalties on net DSE Territory sales.

The agreement calls for both parties to participate in a Joint Collaboration Committee (the “JCC”). The JCC is comprised of executive management from each company and the Company will lead in all aspects related to development and DSE will lead in all aspects related to commercialization in the DSE Territory.

Collaboration Revenue

The Company considered the guidance under ASC 606 and concluded that the agreement was in the scope of ASC 606. The Company concluded that the upfront payment of $150.0 million should be included in the transaction price and related to the following performance obligations under the agreement: 1) the license to the Company’s intellectual property and 2) the obligation to provide ongoing regulatory and development activities. The Company used the adjusted market assessment approach in determining the standalone selling price of the Company’s intellectual property and the expected cost plus margin approach in determining the standalone selling price of the Company’s obligation to provide ongoing regulatory and development activities. Accordingly, for the three and six months ended June 30, 2019, the Company recognized $1.0 million and $146.4 million of collaboration revenue related to the $150.0 million upfront payment, respectively. The $146.4 million relates to the performance obligations for the license to the Company’s intellectual property and a portion of ongoing regulatory and development activities conducted during the period ended June 30, 2019, in the amounts of $144.4 million and $2.0 million, respectively. The remaining $3.6 million of the upfront payment was deferred as of June 30, 2019 due to an on-going performance obligation related to the ongoing regulatory efforts related to the MAA in the DSE Territory. This deferred revenue will be recognized ratably over the period leading up to the approval of the MAA acceptance by the EMA.

All future potential milestone amounts were not included in the transaction price, as they were all determined to be fully constrained following the concepts of ASC 606 due to the fact that such amounts hinge on regulatory approval. Additionally, the Company expects that any consideration related to royalties and sales-based milestones will be recognized when the subsequent sales occur.

The Company has not yet recognized any revenue for milestone payments as the related regulatory and commercial milestones have not yet been achieved.

4. Warrants

In connection with the Credit Facility entered into in June 2014, the Company issued a warrant to purchase 8,230 shares of common stock at an exercise price of $15.19. The warrant was recorded at fair value of $0.1 million to additional paid-in-capital in accordance with ASC 815-10 based upon the allocation of the debt proceeds. During the six months ended June 30, 2019, 8,230 warrants were net exercised for 5,813 shares of the Company’s common stock. As of June 30, 2019, the Company has no warrants outstanding.

5. Commitments and Contingencies

On January 12, 2016, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Michigan, against the Company and Tim Mayleben, captioned Kevin L. Dougherty v. Esperion Therapeutics, Inc., et al. (No. 16-cv-10089). The lawsuit alleges that the Company and Mr. Mayleben violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 by allegedly failing to disclose in an August 17, 2015, public statement that the FDA would require a cardiovascular outcomes trial before approving the Company’s lead product candidate. The lawsuit seeks, among other things, compensatory damages in connection with an allegedly inflated stock price between August 18, 2015, and September 28, 2015, as well as attorneys' fees and costs. On May 20, 2016, an amended complaint was filed in the lawsuit and on July 5, 2016, the Company filed a motion to dismiss the amended complaint. On December 27, 2016, the court granted the Company’s motion to dismiss with prejudice and entered judgment in the Company’s favor. On January 24, 2017, the plaintiffs in this lawsuit filed a motion to alter or amend the judgment. In May 2017, the court denied the plaintiff’s motion to alter or amend the judgment. On June 19, 2017, the plaintiffs filed a notice of appeal to the Sixth Circuit Court of Appeals and on September 14, 2017, they filed their opening brief in support of the appeal. The appeal was fully briefed on December 7, 2017, and it was argued before the Sixth Circuit on March 15, 2018. On September 27, 2018, the Sixth Circuit issued an opinion in which it reversed the district court's dismissal and remanded for further proceedings. On

Table of Contents

October 11, 2018, the Company filed a petition for rehearing en banc and, on October 23, 2018, the Sixth Circuit Court of Appeals directed plaintiffs to respond to that petition. On December 3, 2018, the Sixth Circuit denied the Company's petition for en banc rehearing, and on December 11, 2018, the case was returned to the federal district court by mandate from the Sixth Circuit. On December 26, 2018, the Company filed an answer to the amended complaint, and on March 28, 2019, the Company filed its amended answer to the amended complaint. The Company is unable to predict the outcome of this matter and is unable to make a meaningful estimate of the amount or range of loss, if any, that could result from an unfavorable outcome.

On December 15, 2016, a purported stockholder of the Company filed a derivative lawsuit in the Court of Chancery of the State of Delaware against Tim Mayleben, Roger Newton, Mary McGowan, Nicole Vitullo, Dov Goldstein, Daniel Janney, Antonio Gotto Jr., Mark McGovern, Gilbert Omenn, Scott Braunstein, and Patrick Enright. The Company is named as a nominal defendant. The lawsuit alleges that the defendants breached their fiduciary duties to the Company when they made or approved improper statements on August 17, 2015, regarding the Company’s lead product candidate’s path to FDA approval, and failed to ensure that reliable systems of internal controls were in place at the Company. On February 8, 2019, the Company and defendants filed a motion to dismiss the derivative lawsuit. On April 23, 2019, the plaintiff filed an opposition to the motion to dismiss the derivative lawsuit, and the Company filed a reply brief on May 15, 2019. The lawsuit seeks, among other things, any damages sustained by the Company as a result of the defendants’ alleged breaches of fiduciary duties, including damages related to the above-referenced securities class action, an order directing the Company to take all necessary actions to reform and improve its corporate governance and internal procedures, restitution from the defendants, and attorneys’ fees and costs. The Company is unable to predict the outcome of this matter and is unable to make a meaningful estimate of the amount or range of loss, if any, that could result from an unfavorable outcome.

On May 7, 2018, a purported stockholder of the Company filed a putative class action lawsuit in the United States District Court for the Eastern District of Michigan, captioned Kevin Bailey v. Esperion Therapeutics, Inc., et al. (No. 18-cv-11438). An amended complaint was filed on October 22, 2018, against the Company and certain directors and officers. The amended complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 based on allegedly making false and misleading statements and omissions about the safety and tolerability of bempedoic acid, and specifically facts and circumstances surrounding the Phase 3 trial results for bempedoic acid that the Company announced on May 2, 2018. On November 13, 2018, the Company filed a motion to dismiss the amended complaint, and that motion was fully briefed on December 18, 2018. The lawsuit sought, among other things, compensatory damages in connection with an allegedly inflated stock price between February 22, 2017, and May 22, 2018, as well as attorneys’ fees and costs. On February 19, 2019, the court granted the Company’s motion to dismiss with prejudice and entered judgment in the Company’s favor.

There have been no other material changes to the Company’s contractual obligations and commitments and contingencies outside the ordinary course of business from those previously disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, other than the Revenue Interest Purchase Agreement disclosed in Note 8 “Liability Related to the Revenue Interest Purchase Agreement.”

7. Fair Value Measurements

The Company follows accounting guidance that emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value is defined as “the price that would be received to sell an asset or paid to

Table of Contents

transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements are defined on a three level hierarchy:


Level 1 inputs:		Quoted prices for identical assets or liabilities in active markets;

Level 2 inputs:		Observable inputs other than Level 1 prices, such as quoted market prices for similar assets or liabilities or other inputs that are observable or can be corroborated by market data; and

Level 3 inputs:		Unobservable inputs that are supported by little or no market activity and require the reporting entity to develop assumptions that market participants would use when pricing the asset or liability.

The following table presents the Company’s financial assets and liabilities that have been measured at fair value on a recurring basis:

At June 30, 2019, the fair value of the $125.0 million liability related to the sale of future revenues is based on the Company’s current estimates of future revenues expected to be paid to Eiger III SA LLC (“Oberland”), an affiliate of Oberland Capital LLC, over the life of the Revenue Interest Purchase Agreement (“RIPA”). The liability is considered a Level 3 input based on the three level hierarchy. Refer to Note 8 for further information.

There were no transfers between Levels 1, 2 or 3 during the three and six months ended June 30, 2019 and 2018.

8. Liability Related to the Revenue Interest Purchase Agreement

On June 26, 2019, the Company entered into a Revenue Interest Purchase Agreement (“RIPA”) with Oberland, as agent for purchasers party thereto (the “Purchasers”), and the Purchasers named therein, to obtain financing in respect to the commercialization and further development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and other working capital needs. Pursuant to the RIPA, the Company received $125.0 million at closing, less certain transaction expenses. The Company will also be entitled to receive up to approximately $75.0 million in subsequent installments subject to the terms and conditions set forth in the RIPA: (i) $25.0 million upon certain regulatory approval of its product candidates and (ii) $50.0 million, at the Company’s option, upon reaching $100.0 million trailing worldwide six-month net sales any time prior to December 31, 2021 (the “Third Payment”).

As consideration for such payments, the Purchasers will have a right to receive certain revenue interests (the “Revenue Interests”) from the Company based upon net sales of the Company’s certain products, once approved, which

Table of Contents

will be tiered payments initially ranging from 2.5% to 7.5% of the Company’s net sales in the covered territory (the “Covered Territory”); provided that (a) if annual net sales equal or exceed $350.0 million by December 31, 2021 (the “Sales Threshold”), the initially tiered revenue interest rate will be decreased to a single rate of 2.5% of the Company’s net sales in the Covered Territory, beginning on January 1, 2022, and (b) if annual net sales equal or exceed the Sales Threshold and if the Purchasers receive 100% of their invested capital by December 31, 2024, the revenue interest rate will be decreased to a single rate of 0.4% of the Company’s net sales in the Covered Territory beginning on January 1, 2025. If the Third Payment is drawn down by the Company, the applicable royalty rates will increase by one-third. The Covered Territory is the United States, but is subject to expand to include the world-wide net sales if the Company’s annual U.S. net sales are less than $350.0 million for the year ended December 31, 2021. The U.S. net sales milestone thresholds are not to be taken as financial guidance. The Purchasers’ rights to receive the Revenue Interests shall terminate on the date on which the Purchasers have received Revenue Interests payments of 195% of the then aggregate purchase price (the “Cumulative Purchaser Payments”) paid to the Company, unless the RIPA is terminated earlier.

Under the RIPA, the Company has an option (the “Call Option”) to terminate the RIPA and repurchase future Revenue Interests at any time upon advance written notice. Additionally, the Purchasers have an option (the “Put Option”) to terminate the RIPA and to require the Company to repurchase future Revenue Interests upon enumerated events such as a bankruptcy event, an uncured material breach, a material adverse effect or a change of control. If the Put Option is exercised prior to the first anniversary of the closing date by the Purchasers (except pursuant to a change of control), the required repurchase price will be 120% of the Cumulative Purchaser Payments (minus all payments Company has made to the Purchasers in connection with the Revenue Interests). In all other cases, if the Put Option or the Call Option are exercised, the required repurchase price will be 175% of the Cumulative Purchaser Payments (minus all payments Company has made to the Purchasers in connection with the Revenue Interests), if such option is exercised prior to the third anniversary of the closing date, and 195% of the Cumulative Purchaser Payments (minus all payments Company has made to the Purchasers in connection with the Revenue Interests), if such option is exercised thereafter.

In addition, the RIPA contains various representations and warranties, information rights, non-financial covenants, indemnification obligations and other provisions that are customary for a transaction of this nature.

In connection with the arrangement, the Company recorded a liability, referred to as the “Revenue interest liability” in the condensed balance sheets, of $124.4 million, net of $0.6 million of transaction costs in connection with the RIPA. The Company imputes non-cash interest expense associated with this liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. The interest rate on this liability may vary during the term of the agreement depending on a number of factors, including the level of forecasted sales. The Company evaluates the interest rate quarterly based on its current sales forecasts utilizing the prospective method. The Company recorded approximately $0.0 million in interest expense related to this arrangement as of June 30, 2019.

9. Stock Compensation

2017 Inducement Equity Plan

In May 2017, the Company’s board of directors approved the 2017 Inducement Equity Plan (the “2017 Plan”). The number of shares of common stock available for awards under the 2017 Plan was set to 750,000, with any shares of common stock that are forfeited, cancelled, held back upon the exercise or settlement of an award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of common stock, or otherwise terminated (other than by exercise) under the 2017 Plan added back to the shares of common stock available for issuance under the 2017 Plan.

2013 Stock Option and Incentive Plan

In May 2015, the Company's stockholders approved the amended and restated 2013 Stock Option and Incentive Plan (as amended, the “2013 Plan”). The number of shares of common stock available for awards under the 2013 Plan was set to 2,975,000 shares, plus (i) shares of common stock that are forfeited, cancelled, held back upon the exercise or settlement of an award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting,

Table of Contents

satisfied without the issuance of common stock or otherwise terminated (other than by exercise) under the 2013 Plan and the Company's 2008 Incentive Stock Option and Restricted Stock Plan are added back to the shares of common stock available for issuance under the 2013 Plan, and (ii) on January 1, 2016, and each January 1, thereafter, the number of shares of common stock reserved and available for issuance under the 2013 Plan will be cumulatively increased by 2.5% of the number of shares of common stock outstanding on the immediately preceding December 31, or such lesser number of shares of common stock determined by the compensation committee.

The 2017 Plan provides for the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units (“RSUs”), unrestricted stock awards and dividend equivalent rights. The 2013 Plan provides for the granting of stock options, stock appreciation rights, restricted stock awards, RSUs, unrestricted stock awards, cash-based awards, performance share awards and dividend equivalent rights. The Company incurs stock-based compensation expense related to stock options and RSUs. The fair value of RSUs is determined by the closing market price of the Company’s common stock on the date of grant. The fair value of stock options is calculated using a Black-Scholes option pricing model. The Company accounts for stock-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation. Accordingly, compensation costs related to equity instruments granted are recognized over the requisite service periods of the awards on a straight-line basis at the grant-date fair value. In accordance with the adoption of ASU 2016-09, the Company accounts for forfeitures as they occur.

11. Income Taxes

There was no provision for income taxes for the three and six months ended June 30, 2019 and 2018, because the Company has incurred annual operating losses since inception. At June 30, 2019, the Company continues to conclude that it is not more likely than not that the Company will realize the benefit of its deferred tax assets due to its history of losses. Accordingly, a full valuation allowance has been applied against the net deferred tax assets.

12. Net Income (Loss) Per Common Share

Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common stock equivalents outstanding for the period, including shares that potentially could be dilutive if they were exercised during the period, determined using the treasury-stock method.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our annual report on Form 10-K for the fiscal year ended December 31, 2018 and other filings that we make with the Securities and Exchange Commission.

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). These forward-looking statements are based on our management’s belief and assumptions and on information currently available to management. Although we believe that the expectations reflected in these forward-looking statements are reasonable, these statements relate to future events, including our clinical development plans, or our future financial performance and involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements, including in relation to the clinical development or regulatory approval of bempedoic acid and the bempedoic acid / ezetimibe combination tablet to be materially different from any future results, performance or achievements, including in relation to the clinical development or regulatory approval of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, expressed or implied by these forward-looking statements.

Forward-looking statements are often identified by the use of words such as, but not limited to, “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue” or the negative of these terms or other similar terminology. These statements are only predictions. You should not place undue reliance on forward-looking statements because they involve known and unknown risks, uncertainties and other factors, which are, in some cases, beyond our control and that could materially affect results. Factors that may cause actual results to differ materially from current expectations include, among other things, those referred to or discussed in or incorporated by reference into the section titled “Risk Factors” included in Item 1A of Part II of this Quarterly Report on Form 10-Q. If one or more of these risks or uncertainties occur, or if our underlying assumptions prove to be incorrect, actual events or results may vary significantly from those implied or projected by the forward-looking statements. No forward-looking statement is a guarantee of future performance.

The forward-looking statements in this report represent our views as of the date of this quarterly report. Except as required by law, we undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

Overview

Corporate Overview

We are the Lipid Management Company, a late-stage pharmaceutical company focused on developing and commercializing complementary, cost-effective, convenient, once-daily, oral therapies for the treatment of patients with elevated low density lipoprotein cholesterol, or LDL-C. Through scientific and clinical excellence, and a deep understanding of cholesterol biology, the experienced Lipid Management Team at Esperion is committed to developing new LDL-C lowering therapies that will make a substantial impact on reducing global cardiovascular disease, or CVD; the leading cause of death around the world. Bempedoic acid and the bempedoic acid / ezetimibe combination tablet are targeted therapies that are being developed to significantly lower elevated LDL-C levels in patients with hypercholesterolemia, including patients inadequately treated with current lipid-modifying therapies.

On February 20, 2019, we submitted the new drug application, or NDA, for bempedoic acid and on February 26, 2019, we submitted the NDA for the bempedoic acid / ezetimibe combination tablet to the Food and Drug Administration, or FDA, for LDL-C lowering indications. On May 5, 2019, we announced that the FDA accepted the NDAs for bempedoic acid and the bempedoic acid / ezetimibe combination tablet for filing and regulatory review. The Prescription Drug User Fee Act (“PDUFA”) goal date for completion of the bempedoic acid NDA review is set for

Table of Contents

February 21, 2020, and the PDUFA goal date for completion of the bempedoic acid / ezetimibe combination tablet NDA review is set for February 26, 2020. These dates are consistent with our expectations and reflect the standard review period. The FDA has communicated that there is no current plan to hold an advisory committee meeting to discuss the applications.

On February 11, 2019, we submitted the Marketing Authorization Applications, or MAAs, for bempedoic acid and the bempedoic acid / ezetimibe combination tablet to the European Medicines Agency, or EMA. On February 28, 2019, the EMA completed formal validation of the MAAs for bempedoic acid and the bempedoic acid / ezetimibe combination tablet for LDL-C lowering indications.

On January 2, 2019, we entered into a license and collaboration agreement with Daiichi Sankyo Europe GmbH, or DSE. Pursuant to the agreement, we have granted DSE exclusive commercialization rights to bempedoic acid and the bempedoic acid / ezetimibe combination tablet in the European Economic Area and Switzerland, or the DSE Territory. DSE will be responsible for commercialization in the DSE Territory. We remain responsible for clinical development, regulatory and manufacturing activities for the licensed products globally, including in the DSE Territory. Pursuant to the agreement, the consideration consists of a $150.0 million upfront cash payment as well as $150.0 million cash payment upon first commercial sales in the DSE Territory. We are also eligible to receive a substantial additional regulatory milestone payment upon the grant of the marketing authorization in the European Union for the CV risk reduction label, depending on the range of relative risk reduction in the CLEAR Outcomes study. In addition, we are eligible to receive additional sales milestone payments. Finally, we will receive tiered fifteen percent (15%) to twenty-five percent (25%) royalties on net DSE Territory sales.

On June 26, 2019, we entered into a Revenue Interest Purchase Agreement, or RIPA, with Eiger II SA LLC, or Oberland, an affiliate of Oberland Capital LLC, and the Purchasers named therein. Pursuant to the RIPA, Oberland paid us $125.0 million on closing, less certain transaction expenses, and, subject to the RIPA, we are eligible for an additional $25.0 million upon certain regulatory approval of our product candidates and $50.0 million at our option upon reaching certain sales thresholds. As consideration for the payments, Oberland has the right to receive certain revenue interests from us based on the net sales of certain products, once approved, which will be tiered payments initially ranging from 2.5% to 7.5% of our net sales in the covered territory. The initial mid-single digit repayment rate on U.S. revenue steps down to less than one percent rate upon certain revenue achievements. Esperion reacquires 100% revenue rights upon repayment completion. Refer to Note 8 “Liability Related to the Revenue Interest Purchase Agreement” in the Notes to the Condensed Financial Statements for further information.

We are conducting a global cardiovascular outcomes trial, or CVOT, – known as Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes, for bempedoic acid in 12,604 patients with hypercholesterolemia and high CVD risk and who can be considered statin averse. We initiated the CLEAR Outcomes CVOT in December 2016 and expect the study to be fully enrolled in the third quarter of 2019. We intend to use positive results from this CVOT to support submissions for a CV risk reduction indication in the U.S. and Europe by 2022.

We were incorporated in Delaware in January 2008, and commenced our operations in April 2008. Since our inception, we have focused substantially all of our efforts and financial resources on developing bempedoic acid and the bempedoic acid / ezetimibe combination tablet. We have funded our operations to date primarily through proceeds from sales of preferred stock, convertible promissory notes and warrants, public offerings of common stock, the incurrence of indebtedness, through collaborations with third parties and revenue interest purchase agreements, and we have incurred losses in each year since our inception.

We do not have any products approved for sale. To date, we have not generated any revenue from the sales of bempedoic acid or the bempedoic acid / ezetimibe combination tablet. In the three and six months ended June 30, 2019, the collaboration agreement with DSE provided $1.0 million and $146.4 million in revenue, respectively, driving a net loss of $54.2 million in the three months ended June 30, 2019 and net income of $33.2 million in the six months ended June 30, 2019. The three months ended March 31, 2019 was the first quarter we have been profitable. We incurred a net loss of $45.7 million and $91.9 million for the three and six months ended June 30, 2018. All of our prior net losses resulted from costs incurred in connection with research and development programs, general and administrative costs

Table of Contents

associated with our operations. We expect to incur significant expenses and operating losses for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, including, among others:

●

completing the clinical development activities for the CLEAR Outcomes CVOT;

●

seeking regulatory approvals for bempedoic acid and the bempedoic acid / ezetimibe combination tablet;

●

commercializing bempedoic acid and the bempedoic acid / ezetimibe combination tablet, if approved; and

●

operating as a public company.

Accordingly, we may need additional financing to support our continuing operations and further the development of our product candidates. We may seek to fund our operations and further development activities through collaborations with third parties, strategic alliances, licensing arrangements, permitted debt financings, permitted public or private equity offerings or through other sources. Adequate additional financing may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would have a material adverse effect on our financial condition and our ability to pursue our business strategy or continue operations. We will need to generate significant revenues to achieve profitability, and we may never do so.

Product Overview

Bempedoic acid is our lead, non-statin, orally available, once-daily, LDL-C lowering therapy. With a targeted mechanism of action, bempedoic acid is a first-in-class, ATP Citrate Lyase, or ACL, inhibitor that reduces cholesterol biosynthesis and lowers LDL-C by up-regulating the LDL receptor. Similar to statins, bempedoic acid also reduces high sensitivity C-reactive protein, or hsCRP, a key marker of inflammation associated with cardiovascular disease. Completed Phase 3 studies conducted in more than 4,000 patients, with over 2,600 patients treated with bempedoic acid, demonstrated up to 18 percent placebo corrected LDL-C lowering when used with moderate- and high-intensity statins and 21 to 28 percent placebo corrected LDL-C lowering when used with low dose or no background statin.

Through the complementary mechanisms of action of inhibition of cholesterol synthesis (bempedoic acid) and inhibition of cholesterol absorption (ezetimibe), the bempedoic acid / ezetimibe combination tablet is a non-statin, orally available, once-daily, LDL-C lowering therapy. Inhibition of ACL by bempedoic acid reduces cholesterol biosynthesis and lowers LDL-C by up-regulating the LDL receptor. Inhibition of Niemann-Pick C1-Like 1 by ezetimibe results in reduced absorption of cholesterol from the gastrointestinal tract, thereby reducing delivery of cholesterol to the liver, which in turn upregulates the LDL receptors. Phase 3 data demonstrated that this combination results in a 29 percent placebo corrected LDL-C lowering when used with maximally tolerated statins, a 44 percent LDL-C lowering when used with no background statin (post-hoc analysis), and a 34 percent reduction in hsCRP.

During the six months ended June 30, 2019, we incurred $56.9 million in expenses related to our CLEAR Outcomes CVOT, our open-label extension study, and our 1002FDC-058 study.

During the six months ended June 30, 2018, we incurred $61.0 million in expenses related to the four studies in our global pivotal Phase 3 LDL-C lowering program, our CLEAR Outcomes CVOT, our 1002FDC-053 study, our open-label extension study, our 1002FDC-058 study and our Phase 2 (1002-39) clinical study of bempedoic acid when added-on to an injectable proprotein convertase subtilisin/kexin type 9 inhibitor, or PCSK9i, therapy in patients with hypercholesterolemia.

Program Developments

Results from the initial clinical study of the 100 mg modified release formulation of bempedoic acid demonstrated consistent twenty nine percent (29%) LDL-C lowering, with approximately one-half the active pharmaceutical ingredient of the current 180 mg bempedoic acid tablet, as well as favorable safety and Pharmacokinetics, or PK, parameters. These results provide initial proof-of-concept for the modified release formulation

of bempedoic acid to increase efficacy, extend the patent life of the bempedoic acid franchise into 2038 while utilizing a 505(b)(2) regulatory pathway to approval, and reduce manufacturing costs.

Ongoing Clinical Studies

1002FDC-058 – Phase 2 efficacy and safety study of the bempedoic acid / ezetimibe combination tablet in patients with hypercholesterolemia and Type 2 Diabetes

1002FDC-058 is a Phase 2 clinical study assessing the efficacy and safety of the bempedoic acid / ezetimibe combination tablet in patients with hypercholesterolemia and type 2 diabetes. Initiated in June 2018, the 12-week, randomized, double-blind, placebo-controlled, parallel-dose study consists of three treatment arms evaluating the efficacy and safety of a once-daily, oral fixed dose combination tablet of bempedoic acid 180 mg and ezetimibe 10 mg versus placebo and versus ezetimibe 10 mg alone. The study is expected to enroll approximately 179 patients at approximately 42 sites across the U.S. The co-primary objectives of the study are to assess the 12-week LDL-C lowering efficacy in patients treated with the bempedoic acid / ezetimibe combination tablet versus placebo and versus ezetimibe 10 mg alone. Secondary objectives include evaluating 12-week hsCRP, non-HDL-C, apolipoprotein B, or apoB, total cholesterol and triglycerides. Exploratory objectives include 12-week HbA1c, fasting glucose, fasting insulin and additional glycemic measurements. We expect to report top-line results in the third quarter of 2019.

Open-Label Extension of Study 1—Global pivotal Phase 3 long-term safety and tolerability study in patients with hypercholesterolemia on maximally tolerated background lipid-modifying therapy

Safety data will be obtained from an open-label extension study which completed enrollment of 1,462 of the 2,230 patients enrolled in Study 1 in March 2018. Initiated in February 2017, this open-label extension study will evaluate the long-term safety of bempedoic acid 180 mg in high CVD risk patients with hypercholesterolemia and with atherosclerotic cardiovascular disease, or ASCVD, and/or heterozygous familial hypercholesterolemia, or HeFH, whose LDL-C is not adequately controlled with current lipid-modifying therapies, and who are taking maximally tolerated statin therapy. This open-label extension study will be conducted at approximately 100 sites included in the parent study in the U.S., Canada and Europe. The primary objective is to assess the long-term safety in patients treated with bempedoic acid for up to 1.5 years. Secondary objectives include evaluating the 52- and 78-week effects of bempedoic acid on lipid and cardiometabolic risk markers, including LDL-C, non-HDL-C, total cholesterol, apoB and hsCRP. The open-label extension study will be completed in the fourth quarter of 2019.

Global Cardiovascular Outcomes Trial—CLEAR Outcomes

CLEAR Outcomes is an event driven, global, randomized, double-blind, placebo-controlled study to assess the effects of bempedoic acid in patients with ASCVD and/or HeFH, or who are at high risk for CVD, with hypercholesterolemia and who are only able to tolerate less than the lowest approved daily starting dose of a statin and can be considered statin averse. The CLEAR Outcomes CVOT is expected to enroll approximately 12,600 patients with ASCVD or at high risk for CVD in over 1,000 sites in approximately 30 countries. The study is expected to enroll over a 30 month period with a total estimated study duration of approximately 4.75 years. The expected average treatment duration will be 3.75 years with a minimum treatment duration of approximately 2.25 years. Patients enrolling in the study will be required to have a history of, or be at high risk for, CVD with LDL-C levels greater than 100 mg/dL despite background lipid-lowering therapy, resulting in an expected average baseline LDL-C level in all patients of approximately 135 mg/dL. The primary efficacy endpoint of the event-driven global study is the effect of bempedoic acid versus placebo on the risk of major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization; also referred to as "four-component MACE"). We initiated CLEAR Outcomes in December 2016, closed patient screening in June 2019, and expect to complete enrollment during the third quarter of 2019. The study is intended to support our submissions for a CV risk reduction indication in the U.S. and Europe by 2022.

Financial Operations Overview

Revenue

To date, we have not generated any revenue from product sales. In the future, we may never generate revenue from the sale of bempedoic acid or the bempedoic acid / ezetimibe combination tablet or other product candidates. In the three and six months ended June 30, 2019, we recognized $1.0 million and $146.4 million of revenue associated with the $150.0 million upfront payment from our collaboration agreement with DSE. We expect to recognize the remaining $3.6 million ratably over the period leading up to the approval of the MAA acceptance by the EMA due to an ongoing performance obligation related to the ongoing regulatory efforts for the MAA in the DSE Territory. If we fail to complete the development of bempedoic acid or the bempedoic acid / ezetimibe combination tablet or any other product candidates and secure approval from regulatory authorities, our ability to generate future revenue and our results of operations and financial position will be adversely affected.

Research and Development Expenses

Since our inception, we have focused our resources on our research and development activities, including conducting nonclinical, preclinical and clinical studies. Our research and development expenses consist primarily of costs incurred in connection with the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, which include:

●

expenses incurred under agreements with consultants, contract research organizations, or CROs, and investigative sites that conduct our preclinical and clinical studies;

●

the cost of acquiring, developing and manufacturing clinical study materials and commercial product manufacturing supply as we approach anticipated approval, including the procurement of ezetimibe in our continued development of our bempedoic acid / ezetimibe combination tablet;

●

employee-related expenses, including salaries, benefits, stock-based compensation and travel expenses;

●

allocated expenses for rent and maintenance of facilities, insurance and other supplies; and

●

costs related to compliance with regulatory requirements.

We expense research and development costs as incurred. To date, substantially all of our research and development work has been related to bempedoic acid and the bempedoic acid / ezetimibe combination tablet. Costs for certain development activities, such as clinical studies, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided to us by our vendors. Our direct research and development expenses consist principally of external costs, such as fees paid to investigators, consultants, central laboratories and CROs in connection with our clinical studies. We do not allocate acquiring and manufacturing clinical study materials, salaries, stock-based compensation, employee benefits or other indirect costs related to our research and development function to specific programs.

Our research and development expenses are expected to continue in the foreseeable future as they relate to our ongoing CLEAR Outcomes CVOT, our NDA and MAA submissions, commercial product manufacturing supply as we approach anticipated approval and any other development programs or additional indications we choose to pursue. We cannot determine with certainty the duration and completion costs associated with the ongoing or future clinical studies of bempedoic acid and the bempedoic acid / ezetimibe combination tablet. Also, we cannot conclude with certainty if, or when, we will generate revenue from the commercialization and sale of bempedoic acid or the bempedoic acid / ezetimibe combination tablet, if ever. We may never succeed in obtaining regulatory approval for bempedoic acid or the bempedoic acid / ezetimibe combination tablet. The duration, costs and timing associated with the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet will depend on a variety of factors, including uncertainties associated with the results of our clinical studies and our ability to obtain regulatory approval. For example, if the FDA or another regulatory authority were to require us to conduct clinical studies beyond

Table of Contents

those that we currently anticipate will be required for the completion of clinical development or post-commercialization clinical studies of bempedoic acid or the bempedoic acid / ezetimibe combination tablet, or if we experience significant delays in enrollment in any of our clinical studies, we could be required to expend significant additional financial resources and time on the completion of clinical development or post-commercialization clinical studies of bempedoic acid and the bempedoic acid / ezetimibe combination tablet.

General and Administrative Expenses

General and administrative expenses primarily consist of salaries and related costs for personnel, including stock-based compensation, associated with our executive, accounting and finance, commercial, operational and other administrative functions. Other general and administrative expenses include facility-related costs, communication expenses and professional fees for legal, patent prosecution, protection and review, consulting and accounting services.

We anticipate that our general and administrative expenses will increase in the future in connection with the continued research and development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, increases in our headcount, expansion of our information technology infrastructure, and increased expenses associated with being a public company and complying with exchange listing and Securities and Exchange Commission, or SEC, requirements. These increases will likely include higher legal, compliance, accounting and investor and public relations expenses.

Other Income, Net

Other income, net, primarily relates to interest income and the accretion or amortization of premiums and discounts earned on our cash, cash equivalents and investment securities. Costs during the three and six months ended June 30, 2018 also includes interest expense associated with our credit facility and non-cash interest costs associated with the amortization of the related debt discount, deferred issuance costs and final payment fee.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our financial statements. We evaluate our estimates and judgments on an ongoing basis, including those related to accrued expenses and stock-based compensation. We base our estimates on historical experience, known trends and events, contractual milestones and other various 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. Our actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition - Collaboration Revenue

We have entered into an agreement related to our activities to develop, manufacture, and commercialize our product candidates. We earn collaboration revenue in connection with a collaboration agreement to develop and/or commercialize product candidates where we deem the collaborator to be our customer. We have adopted ASC 606, Revenue from Contracts with Customers, and under the terms of the standard, revenue is measured as the amount of consideration we expect to be entitled to in exchange for transferring promised goods or providing services to a customer. Revenue is recognized when (or as) we satisfy performance obligations under the terms of a contract. Depending on the terms of the arrangement, we may defer the recognition of all or a portion of the consideration received as the performance obligations are satisfied.

The collaboration agreement may require us to deliver various rights, services, and/or goods across the entire life cycle of a product or product candidate. In the agreement involving multiple goods or services promised to be transferred to a customer, we must assess, at the inception of the contract, whether each promise represents a separate

Table of Contents

performance obligation (i.e., is "distinct"), or whether such promises should be combined as a single performance obligation.

The terms of the agreement typically include consideration to be provided to us in the form of non-refundable up-front payments, development milestones, sales milestones, and royalties on sales of products within a respective territory.

At the inception of the contract, the transaction price reflects the amount of consideration we expect to be entitled to in exchange for transferring promised goods or services to our customer. In the arrangement where we satisfy performance obligation(s) during the regulatory phase over time, we recognize collaboration revenue typically using an input method on the basis of our regulatory costs incurred relative to the total expected cost which determines the extent of our progress toward completion. We review the estimate of the transaction price and the total expected cost each period, and make revisions to such estimates as necessary.

Under our collaboration agreement, product sales and cost of sales may be recorded by our collaborators as they are deemed to be the principal in the transaction. We receive royalties from the commercialization of such products, and record our share of the variable consideration, representing a percentage of net product sales, as collaboration revenue in the period in which such underlying sales occur and costs are incurred by our collaborator. Our collaborator will provide us with estimates of our royalties for such quarter; these estimates are reconciled to actual results in the subsequent quarter, and the royalty is adjusted accordingly, as necessary.

Recent Accounting Pronouncements

In November 2018, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU, 2018-08, which clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue under Accounting Standards Codification, or ASC, 606 when the collaborative arrangement participant is a customer in the context of a unit of account. The standard is effective for public companies for fiscal years beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted, included in any interim period, provided an entity has already adopted ASC 606 or does so concurrently with the adoption of this guidance. We early adopted this guidance as of January 1, 2019, and implemented the new guidance in our consideration of the accounting for the DSE collaboration signed on January 2, 2019. Refer to Note 2 “Summary of Significant Accounting Policies” and Note 3 “Collaborations with Third Parties” in the Notes to the Condensed Financial Statements for further information.

In February 2016, the FASB issued ASU 2016-02, which was amended by subsequent updates (collectively the “lease standard” or “ASC 842”), and is intended to improve financial reporting about leasing transactions. The updated guidance requires a lessee to recognize assets and liabilities for leases with lease terms of more than twelve months. We adopted this standard on January 1, 2019 using the modified retrospective method. Results for the reporting period beginning after December 31, 2018 have been presented in accordance with the standard, while results for prior periods have not been adjusted. We recognized $1.0 million and $1.0 million of operating lease assets and operating lease liabilities, respectively, on our balance sheets as of January 1, 2019, primarily related to the lease agreement for our principal executive office. Refer to Note 9 “Leases” in the Notes to the Condensed Financial Statements for further information.

There have been no other material changes to the significant accounting policies previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

We have funded our operations to date primarily through proceeds from sales of preferred stock, convertible promissory notes and warrants, public offerings of common stock, the incurrence of indebtedness, milestone payments from collaboration agreements and revenue interest purchase agreements. Pursuant to the license and collaboration agreement with DSE signed on January 2, 2019, we received an upfront cash payment of $150.0 million from DSE and are eligible for substantial additional sales and regulatory milestone payments and royalties. Pursuant to the RIPA with Oberland Capital LLC, we received an upfront cash payment of $124.4 million, net of issuance costs, and are eligible for an additional $25.0 million upon certain regulatory approval of our product candidates and $50.0 million at our option upon reaching certain sales thresholds. In return, Oberland will have a right to receive revenue interests based on net

sales of our product candidates. To date, we have not generated any revenue from product sales and we anticipate that we will incur losses for the foreseeable future.

As of June 30, 2019, our primary sources of liquidity were our cash and cash equivalents and available-for-sale investments, which totaled $274.3 million and $26.9 million, respectively. We invest our cash equivalents and investments in highly liquid, interest-bearing investment-grade and government securities to preserve principal.

The following table summarizes the primary sources and uses of cash for the periods presented below:


	Six Months Ended June 30,
	2019		2018
	(in thousands)
Cash provided by (used in) operating activities	$	37,682	$	(82,419)
Cash provided by investing activities		72,412		61,853
Cash provided by financing activities		128,205		10,478
Net increase (decrease) in cash and cash equivalents	$	238,299	$	(10,088)

Operating Activities

We have incurred and expect to continue to incur, significant costs in the areas of research and development, regulatory and other clinical study costs, associated with the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and our operations.

Net cash provided by operating activities totaled $37.7 million for six months ended June 30, 2019, consisting of the $150.0 million upfront payment from the DSE collaboration offset by cash used to fund the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, adjusted for non-cash expenses such as stock-based compensation expense, depreciation and amortization and changes in working capital. Net cash used in operating activities totaled $82.4 million for the six months ended June 30, 2018. The primary use of our cash for the six months ended June 30, 2018 was to fund the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, adjusted for non-cash expenses such as stock-based compensation expense, depreciation and amortization and changes in working capital.

Investing Activities

Net cash provided by investing activities of $72.4 million and $61.9 million for the six months ended June 30, 2019 and 2018, respectively, consisted primarily of proceeds from the sale and maturities of highly liquid, interest-bearing investment-grade and government securities.

Financing Activities

Net cash provided by financing activities of $128.2 million for the six months ended June 30, 2019 related primarily to the upfront cash received from the RIPA with Oberland. Net cash provided by financing activities of $10.5 million for the six months ended June 30, 2018 related primarily to proceeds from exercise of our common stock options.

Plan of Operations and Funding Requirements

We expect to continue to incur significant expenses and operating losses for the foreseeable future in connection with our ongoing CLEAR Outcomes CVOT, NDA and MAA submissions and commercial launch activities. Pursuant to the license and collaboration agreement with DSE, we received an upfront cash payment of $150.0 million from DSE and are eligible for substantial additional sales and regulatory milestone payments and royalties, including an additional $150.0 million upon first commercial sale in the DSE Territory. Pursuant to the RIPA with Oberland, we received an upfront cash payment of $125.0 million and may be eligible for an additional $25.0 million upon certain regulatory approval of our product candidates and $50.0 million at our option upon reaching certain sales thresholds. In

return, Oberland will have a right to receive revenue interests from us based on net sales of certain of our products. We estimate that current cash resources and proceeds to be received in the future under the DSE collaboration agreement and the RIPA with Oberland are sufficient to fund operations through the expected approvals of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and the commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, if approved for an LDL-C lowering indication. We may, however, need to secure additional cash resources to continue to fund the commercialization and further development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet. We have based these estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and the extent to which we entered and may enter into collaborations with pharmaceutical partners regarding the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, we are unable to estimate the amounts of increased capital outlays and operating expenses associated with completing the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet. Our future funding requirements will depend on many factors, including, but not limited to:

●

our ability to successfully develop and commercialize bempedoic acid and the bempedoic acid / ezetimibe combination tablet or other product candidates;

●

the costs, timing and outcomes of our CLEAR Outcomes CVOT and other ongoing clinical studies of bempedoic acid and the bempedoic acid / ezetimibe combination tablet;

●

the time and cost necessary to obtain regulatory approvals for bempedoic acid and the bempedoic acid / ezetimibe combination tablet, if at all;

●

our ability to establish a sales, marketing and distribution infrastructure to commercialize bempedoic acid and the bempedoic acid / ezetimibe combination tablet or our ability to establish any future collaboration or commercialization arrangements on favorable terms, if at all;

●

our ability to realize the intended benefits of our existing and future collaboration and partnerships;

●

the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims; and

●

the implementation of operational and financial information technology.

Until such time, if ever, as we can generate U.S. substantial product revenues, we expect to finance our cash needs through a combination of collaborations with third parties, strategic alliances, licensing arrangements, permitted debt financings, permitted royalty-based financings and equity offerings or other sources. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available and permitted under the terms of our RIPA, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with pharmaceutical partners or royalty-based financing arrangements, such as the collaboration arrangement with DSE and the RIPA with Oberland, we may have to relinquish valuable rights to our technologies, future revenue streams or grant licenses on terms that may not be favorable to us. For instance, as part of the RIPA with Oberland, Oberland has the right to receive certain revenue interests from us based on the net sales of certain products, once approved, and we have granted Oberland a senior security interest in certain of our assets. If our cash flows and capital resources are insufficient to allow us to make required payments, we may have to reduce or delay capital expenditures, sell assets or seek additional capital. If we raise funds by selling additional equity, such sale would result in dilution to our stockholders. If we are unable to raise additional funds through equity or permitted debt financings or through collaborations, strategic alliances or licensing arrangements or permitted royalty-based financing arrangements when needed, we may be required to delay, limit, reduce or terminate our product development or future

commercialization efforts or grant rights to develop and market bempedoic acid and the bempedoic acid / ezetimibe combination tablet that we would otherwise prefer to develop and market ourselves.

Contractual Obligations and Commitments

On June 26, 2019, we entered into a RIPA with Oberland. Pursuant to the RIPA, Oberland paid us $125.0 million at closing, less certain transaction expenses, and, subject to the terms and conditions of the RIPA, we are eligible for an additional $25.0 million upon certain regulatory approval of our product candidates and $50.0 million at our option upon reaching certain sales thresholds. As consideration for the payments, Oberland has the right to receive certain revenue interests from us based on the net sales of certain products, once approved, which will be tiered payments initially ranging from 2.5% to 7.5% of our net sales in the covered territory (as detailed in the RIPA). The initial mid-single digit repayment rate on U.S. revenue steps down to less than one percent rate upon certain revenue achievements. Esperion reacquires 100% revenue rights upon repayment completion. We recorded the proceeds from the RIPA as a liability on the consolidated balance sheets and are accounting for the RIPA under the effective-interest method over the estimated life of the RIPA. Refer to Note 8 “Liability Related to the Revenue Interest Purchase Agreement” in the Notes to the Condensed Financial Statements for further information.

There have been no other material changes to our contractual obligations and commitments outside the ordinary course of business from those previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

Off-Balance Sheet Arrangements

We do not currently have, nor did we have during the periods presented, any off-balance sheet arrangements as defined by Securities and Exchange Commission rules.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We had cash and cash equivalents and available-for-sale investments of approximately $274.3 million and $26.9 million at June 30, 2019, and $37.0 million and $99.3 million at December 31, 2018, respectively. The primary objectives of our investment activities are to preserve principal, provide liquidity and maximize income without significantly increasing risk. Our primary exposure to market risk relates to fluctuations in interest rates which are affected by changes in the general level of U.S. interest rates. Given the short-term nature of our cash and cash equivalents, we believe that a sudden change in market interest rates would not be expected to have a material impact on our financial condition and/or results of operation. We do not have any foreign currency or other derivative financial instruments.

We do not believe that our cash, cash equivalents and available-for-sale investments have significant risk of default or illiquidity. While we believe our cash and cash equivalents do not contain excessive risk, we cannot provide absolute assurance that in the future our investments will not be subject to adverse changes in market value. In addition, we maintain significant amounts of cash and cash equivalents at one or more financial institutions that are in excess of federally insured limits.

We contract with CROs and investigational sites globally. We are therefore subject to fluctuations in foreign currency rates in connection with these agreements. We do not hedge our foreign currency exchange rate risk. We do not believe that fluctuations in foreign currency rates have had a material effect on our results of operations during the six months ended June 30, 2019.

Inflation generally affects us by increasing our cost of labor and clinical study costs. We do not believe that inflation has had a material effect on our results of operations during the six months ended June 30, 2019.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities and Exchange Act of 1934 is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our President and Chief Executive Officer, who is our principal executive officer, and our Chief Financial Officer, who is our principal financial officer, to allow timely decisions regarding required disclosure.

As of June 30, 2019, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of June 30, 2019, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

On January 12, 2016, a purported stockholder of our company filed a putative class action lawsuit in the United States District Court for the Eastern District of Michigan, against us and Tim Mayleben, captioned Kevin L. Dougherty v. Esperion Therapeutics, Inc., et al. (No. 16-cv-10089). The lawsuit alleges that we and Mr. Mayleben violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 by allegedly failing to disclose in an August 17, 2015, public statement that the FDA would require a cardiovascular outcomes trial before approving our lead product candidate. The lawsuit seeks, among other things, compensatory damages in connection with an allegedly inflated stock price between August 18, 2015, and September 28, 2015, as well as attorneys’ fees and costs. On May 20, 2016, an amended complaint was filed in the lawsuit and on July 5, 2016, we filed a motion to dismiss the amended complaint. On December 27, 2016, the court granted our motion to dismiss with prejudice and entered judgment in our favor. On January 24, 2017, the plaintiffs in this lawsuit filed a motion to alter or amend the judgment. In May 2017, the court denied the plaintiff’s motion to alter or amend the judgment. On June 19, 2017, the plaintiffs filed a notice of appeal to the Sixth Circuit Court of Appeals and on September 14, 2017, they filed their opening brief in support of the appeal. The appeal was fully briefed on December 7, 2017, and it was argued before the Sixth Circuit on March 15, 2018. On September 27, 2018, the Sixth Circuit issued an opinion in which it reversed the district court’s dismissal and remanded for further proceedings. On October 11, 2018, we filed a petition for rehearing en banc and, on October 23, 2018, the Sixth Circuit of Appeals directed plantiffs to respond to that petition. On December 3, 2018, the Sixth Circuit denied our petition for en banc rehearing, and on December 11, 2018, the case was returned to the federal district court by mandate from the Sixth Circuit. On December 26, 2018, we filed our answer to the amended complaint, and on March 28, 2019, we filed our amended answer to the amended complaint. We are unable to predict the outcome of this matter and are unable to make a meaningful estimate of the amount or range of loss, if any, that could result from an unfavorable outcome.

On December 15, 2016, a purported stockholder of our company filed a derivative lawsuit in the Court of Chancery of the State of Delaware against Tim Mayleben, Roger Newton, Mary McGowan, Nicole Vitullo, Dov

Table of Contents

Goldstein, Daniel Janney, Antonio Gotto Jr., Mark McGovern, Gilbert Omenn, Scott Braunstein, and Patrick Enright. Our company is named as a nominal defendant. The lawsuit alleges that the defendants breached their fiduciary duties to the company when they made or approved improper statements on August 17, 2015, regarding our lead product candidate’s path to FDA approval, and failed to ensure that reliable systems of internal controls were in place at our company. On February 8, 2019, we and the defendants filed a motion to dismiss the derivative lawsuit. On April 23, 2019, the plaintiff filed an opposition to the motion to dismiss the derivative lawsuit, and we filed a reply brief on May 15, 2019. The lawsuit seeks, among other things, any damages sustained by us as a result of the defendants’ alleged breaches of fiduciary duties, including damages related to the above-referenced securities class action, an order directing us to take all necessary actions to reform and improve our corporate governance and internal procedures, restitution from the defendants, and attorneys’ fees and costs. We are unable to predict the outcome of this matter and are unable to make a meaningful estimate of the amount or range of loss, if any, that could result from an unfavorable outcome.

On May 7, 2018, a purported stockholder of our company filed a putative class action lawsuit in the United States District Court for the Eastern District of Michigan, captioned Kevin Bailey v. Esperion Therapeutics, Inc., et al. (No. 18-cv-11438). An amended complaint was filed on October 22, 2018, against us and certain directors and officers. The amended complaint alleges violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 based on allegedly making false and misleading statements and omissions about the safety and tolerability of bempedoic acid, and specifically facts and circumstances surrounding the Phase 3 trial results for bempedoic acid that we announced on May 2, 2018. On November 13, 2018, we filed a motion to dismiss the amended complaint, and that motion was fully briefed on December 18, 2018. The lawsuit sought, among other things, compensatory damages in connection with an allegedly inflated stock price between February 22, 2017, and May 22, 2018, as well as attorneys’ fees and costs. On February 19, 2019, the court granted our motion to dismiss with prejudice and entered judgment in our favor.

There have been no other material changes to our legal proceedings outside the ordinary course of business from those previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018.

In the future, we may become party to legal matters and claims arising in the ordinary course of business, the resolution of which we do not anticipate would have a material adverse impact on our financial position, results of operations or cash flows.

Item 1A. Risk Factors

Except for the historical information contained herein or incorporated by reference, this report and the information incorporated by reference contains forward-looking statements that involve risks and uncertainties. These statements include projections about our accounting and finances, plans and objectives for the future, future operating and economic performance and other statements regarding future performance. These statements are not guarantees of future performance or events. Our actual results could differ materially from those discussed in this report. Factors that could cause or contribute to these differences include, but are not limited to, those discussed in the following section, as well as those discussed in Part I, Item 2 entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere throughout this report and in any documents incorporated in this report by reference.

You should consider carefully the following risk factors, together with those set forth in Part I, Item 1A in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 and in all of the other information included or incorporated in this report and other filings that we make with the Securities and Exchange Commission. The following risk factors represent new risk factors or those containing changes, including material changes, to the risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2018. If any of the previously identified or following risks, either alone or taken together, or other risks not presently known to us or that we currently believe to not be significant, develop into actual events, then our business, financial condition, results of operations or prospects could be materially adversely affected. If that happens, the market price of our common stock could decline, and stockholders may lose all or part of their investment.

Risks Related to the Securities Markets and Investment in our Common Stock

We may be at an increased risk of securities class action litigation.

Historically, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This risk is especially relevant for us because biotechnology and pharmaceutical companies have experienced significant stock price volatility in recent years. For example, a purported securities class action lawsuit was filed in January 2016 naming us and certain of our officers as defendants. In December 2016, the federal district court granted our motion to dismiss with prejudice and entered judgment in our favor. In May 2017, the court denied plaintiffs' motion to alter or amend that judgment. On June 19, 2017, plaintiffs filed a notice of appeal to the Sixth Circuit Court of Appeals and on September 14, 2017, they filed their opening brief in support of the appeal. The appeal was fully briefed on December 7, 2017, and it was argued before the Sixth Circuit on March 15, 2018. On September 27, 2018, the Sixth Circuit issued an opinion in which it reversed the district court’s dismissal and remanded for further proceedings. On October 11, 2018, we filed a petition for rehearing en banc and, on October 23, 2018, the Sixth Circuit Court of Appeals directed plaintiffs to respond to that petition. On December 3, 2018, the Sixth Circuit Court of Appeals denied our petition for en banc rehearing, and on December 11, 2018, the case was returned to the federal district court by mandate from the Sixth Circuit. On December 26, 2018, we filed our answer to the amended complaint, and on March 28, 2019, we filed our amended answer to the amended complaint.

Additionally, in December 2016, a purported derivative action was filed in Delaware against certain of our directors and officers. In February 2019, our company and defendants filed a motion to dismiss the derivative lawsuit. In April 2019, the plaintiff filed an opposition to the motion to dismiss the derivative lawsuit, and we filed a reply brief in May 2019. In May 2018, a purported securities class action lawsuit was filed naming us and certain of our officers as defendants. In November 2018, we filed a motion to dismiss and such motion was fully briefed in December 2018. In February 2019, the court granted our motion to dismiss with prejudice and entered judgment in our favor.

Any lawsuit to which we or our directors or officers are a party, with or without merit, may result in an unfavorable judgment. We also may decide to settle lawsuits on unfavorable terms. Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation or adverse changes to our offerings or business practices. Any of these results could adversely affect our business. In addition, defending claims is costly and can impose a significant burden on our management. This proceeding and any others in which we may become involved could result in substantial costs and a diversion of management's attention and resources, which could harm our business.

Our payment obligations under the Revenue Interest Purchase Agreement with Oberland may adversely affect our financial position or results of operations and our ability to raise additional capital which in turn may increase our vulnerability to adverse regulatory developments or economic or business downturns.

As described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources,” on June 26, 2019, we entered into a Revenue Interest Purchase Agreement, or RIPA, with Eiger II SA LLC, or Oberland, an affiliate of Oberland Capital LLC, and the Purchasers named therein. Pursuant to the RIPA, Oberland paid us $125.0 million on closing, less certain transaction expenses, and, subject to the terms and conditions in the RIPA, we are eligible for an additional $25.0 million upon certain regulatory approval of our product candidates and $50.0 million at our option upon reaching certain sales thresholds. As consideration for the payments, Oberland has the right to receive certain revenue interests from us based on the net sales of certain products, once approved, which will be tiered payments initially ranging from 2.5% to 7.5% of our net sales in the covered territory.

The RIPA and the revenue interest stream payable to Oberland could have important negative consequences to the holders of our securities. For example, a portion of our cash flow from operations will be needed to pay certain revenue interests to Oberland and will not be available to fund future operations. Additionally, we may have increased vulnerability to adverse general economic and industry conditions.

Payment requirements under the RIPA will increase our cash outflows. Our future operating performance is subject to market conditions and business factors that are beyond our control. If our cash inflows and capital resources

Table of Contents

are insufficient to allow us to make required payments, we may have to reduce or delay capital expenditures, sell assets or seek additional capital. If we raise funds by selling additional equity, such sale would result in dilution to our stockholders. There is no assurance that if we are required to secure funding we can do so on terms acceptable to us, or at all. Failure to pay certain amounts to Oberland when due would result in a default under the RIPA and result in foreclosure on certain of our assets which would have a material adverse effect.

The RIPA contains customary affirmative and negative non-financial covenants and events of default, including, covenants and restrictions that among other things, grant a senior security interest in our assets and restrict our ability to incur liens, incur additional indebtedness, make loans and investments, engage in mergers and acquisitions, and engage in asset sales. Additionally, the Purchasers under the RIPA have an option (the “Put Option”) to terminate the RIPA and to require the Company to repurchase future Revenue Interests upon enumerated events such as a bankruptcy event, an uncured material breach, a material adverse effect (which can include adverse developments related to the regulatory approval of our product candidates) or a change of control. The triggering of the Put Option, including by our failure to comply with these covenants, could permit the Purchasers to declare certain amounts to be immediately due and payable. If we default under the terms of the RIPA, including by failure to make such accelerated payments, the Purchasers take control of our pledged assets. Further, if we are liquidated, the Purchasers’ right to repayment would be senior to the rights of the holders of our common stock. Any triggering of the Put Option or other declaration by the Purchasers of an event of default under the RIPA could significantly harm our financial condition, business and prospects and could cause the price of our common stock to decline.
