1. The Company and Basis of Presentation

Esperion Therapeutics, Inc. ("the Company”) is the Lipid Management Company, a pharmaceutical company focused on developing and commercializing affordable, oral, once-daily, non-statin medicines 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 medicines that will make a substantial impact on reducing global cardiovascular disease ("CVD"); the leading cause of death around the world. NEXLETOL® (bempedoic acid) and NEXLIZET^TM (bempedoic acid and ezetimibe) tablets are the first, oral, once-daily, non-statin LDL-C lowering medicines approved in the U.S. in nearly 20 years for patients with atherosclerotic cardiovascular disease (“ASCVD”) or heterozygous familial hypercholesterolemia (“HeFH”).

On February 21, 2020, the Company announced that the U.S. Food and Drug Administration (“FDA”) approved NEXLETOL an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C. The effect of NEXLETOL on cardiovascular morbidity and mortality has not been determined. NEXLETOL is the first oral, once-daily, non-statin LDL-C lowering medicine approved since 2002 for indicated patients. NEXLETOL became commercially available on March 30, 2020.

On February 26, 2020, the Company announced that the FDA approved NEXLIZET as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C. The effect of NEXLIZET on cardiovascular morbidity and mortality has not been determined. NEXLIZET is the first non-statin, LDL-C lowering fixed combination drug product ever approved. NEXLIZET became commercially available on June 4, 2020.

On January 31, 2020, the Committee for Medicinal Products for Human Use ("CHMP") of the European Medicines Agency ("EMA") adopted a positive opinion for the Marketing Authorisation Applications ("MAAs") of both bempedoic acid and the bempedoic acid / ezetimibe combination tablets, recommending approval for the treatment of hypercholesterolemia and mixed dyslipidemia. On April 6, 2020, the Company announced that the European Commission (“EC”) approved the NILEMDO™ (bempedoic acid) and NUSTENDI™ (bempedoic acid and ezetimibe) tablets for the treatment of hypercholesterolemia and mixed dyslipidemia. The decision is applicable to all 27 European Union member states plus the United Kingdom, Iceland, Norway and Liechtenstein. NILEMDO (bempedoic acid) and NUSTENDI (bempedoic acid and ezetimibe) are the branded products names for bempedoic acid and the bempedoic acid / ezetimibe combination tablets in Europe. NILEMDO is the first, oral, non-statin, LDL-C lowering medicines approved in Europe in almost two decades for indicated patients, and NUSTENDI is the first non-statin, LDL-C lowering combination medicine ever approved in Europe.

On April 17, 2020, the Company entered into a license and collaboration agreement (the "Otsuka Agreement") with Otsuka Pharmaceutical Co., Ltd. ("Otsuka"). Pursuant to the Otsuka Agreement, the Company granted Otsuka exclusive development and commercialization rights to NEXLETOL and NEXLIZET in Japan. Otsuka will be responsible for all development, regulatory, and commercialization activities in Japan. In addition, Otsuka will fund all clinical development costs associated with the program in Japan. The Company received an upfront cash payment of $60 million in April 2020 and will receive up to an additional $450 million in total development and sales milestones. The Company will also receive tiered royalties ranging from 15 percent to 30 percent on net sales in Japan.

On June 18, 2020, the Company entered into an amendment to the license and collaboration agreement ("LCA Amendment") with Daiichi Sankyo Europe GmbH ("DSE") dated as of January 2, 2019. In June 2020, the Company completed the transfer of the MAAs for NILEMDO and NUSTENDI. Pursuant to the terms of the amendment, DSE paid the Company the second $150 million milestone based on completion of the NUSTENDI MAA transfer rather than the first product sale in the EU. Prior to the execution of the LCA Amendment, the milestone payment was due upon the first commercial sale in Europe, which is anticipated later this year. Additionally, the Company and DSE have agreed to expand the territory in which DSE has exclusive commercialization rights to NILEMDO and NUSTENDI to include Turkey. DSE's designated affiliate in Turkey will be solely responsible, at its sole cost and expense, for all regulatory matters relating to such products in Turkey, including obtaining Regulatory Approval for such product in Turkey.

7

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. The Company received approval by the FDA in February 2020 to commercialize NEXLETOL and NEXLIZET in the U.S., and accordingly commenced principal operations on March 30, 2020 with the commercialization of NEXLETOL. The Company is subject to risks and uncertainties which include the need to successfully commercialize its products, research, develop, and clinically test therapeutic products; obtain regulatory approvals for its products; expand its management, commercial 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 net product sales, collaboration agreements with DSE and Otsuka, entered into on January 2, 2019 and April 17, 2020, respectively, 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 products and product candidates through a combination of collaborations with third parties, strategic alliances, licensing arrangements, permitted debt financings, permitted royalty-based financings, and permitted private and public 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 products or future product candidates, or to commercialize its current or future product candidates, if approved.

Basis of Presentation

The accompanying condensed interim 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 prior year amounts have been reclassified to conform with current year presentation. Certain information and disclosures normally included in the annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, 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, 2019, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. 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, net revenues, expenses and related disclosures. Actual results could differ from those estimates.

Concentration of Risk

The Company enters into a limited number of distribution agreements with distributors and specialty pharmacies. The Company's net product sales are with these customers. As of June 30, 2020, 1 customer accounted for all of the Company's net trade receivables.

Inventories

Inventories are stated at the lower of cost or net realizable value and recognized on a first-in, first-out ("FIFO") method. The Company uses standard cost to determine the cost basis for inventory. Inventory is capitalized based on when future economic benefit is expected to be realized. The Company began capitalizing inventory upon receiving FDA approval for NEXLETOL and NEXLIZET on February 21, 2020 and February 26, 2020, respectively. Prior to the FDA approval of NEXLETOL and NEXLIZET, expenses associated with the manufacturing of the Company's products were recorded as research and development expense.

8

The Company analyzes its inventory levels on a periodic basis to determine if any inventory is at risk for expiration prior to sale or has a cost basis that is greater than its estimated future net realizable value. Any adjustments are recognized through cost of sales in the period in which they are incurred.

Revenue Recognition

In accordance with ASC 606, Revenue from Contracts with Customers, the Company recognizes revenue when a customer obtains control of promised goods or services, in an amount that reflects the consideration the Company expects to receive in exchange for the goods or services provided. To determine revenue recognition for arrangements within the scope of ASC 606, the Company performs the following five steps: identify the contracts with a customer; identify the performance obligations in the contract; determine the transaction price; allocate the transaction price to the performance obligations in the contract; and recognize revenue when or as the entity satisfies a performance obligation. At contract inception the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. The Company derives revenue through two primary sources: collaboration revenue and product sales. Collaboration revenue consists of the collaboration payments to the Company for collaboration arrangements outside of the United States for the development, manufacturing and commercialization of the Company's product candidates by the Company's partners and product sales consists of sales of NEXLETOL and NEXLIZET.

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. 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.

The collaboration agreements may require the Company to deliver various rights, services, and/or goods across the entire life cycle of a product or product candidate. In an 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. The Company recognizes regulatory and approval milestones consideration when it is probable that a future reversal is unlikely to occur. For sales based milestones and royalties based on sales of product in a territory, the Company applies the sales-based royalty exception in ASC 606-10-55-65 to all of these milestones and royalties.

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 contracted supply agreements with collaborators, the Company may manufacture and supply quantities of active pharmaceutical ingredient (“API”) or bulk tablets reasonably required by collaboration partners for the development or sale of licensed products in their respective territory. The Company recognizes revenue when the collaboration partner has obtained control of the API or bulk tablets. The Company records the costs related to the supply agreement in cost of goods sold on the condensed statements of operations and comprehensive income (loss).

Under the Company's collaboration agreements, 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.

9

b.Product Sales, Net

On February 21, 2020, the Company announced that the FDA approved NEXLETOL as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C. On February 26, 2020, the Company announced that the FDA approved NEXLIZET as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C. On March 30, 2020, NEXLETOL was commercially available in the U.S. through prescription and on June 4, 2020, NEXLIZET was commercially available in the U.S. through prescription. Net product sales totaled $0.6 million and $1.5 million for the three and six months ended June 30, 2020, respectively.

The Company sells NEXLETOL and NEXLIZET to wholesalers in the U.S and, in accordance with ASC 606, recognizes revenue at the point in time when the customer is deemed to have obtained control of the product. The customer is deemed to have obtained control of the product at the time of physical receipt of the product at the customers’ distribution facilities, or free on board (“FOB”) destination, the terms of which are designated in the contract.

Product sales are recorded at the net selling price, which includes estimates of variable consideration for which reserves are established for (a) rebates and chargebacks, (b) co-pay assistance programs, (c) distribution fees, (d) product returns, and (e) other discounts. Where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as current contractual and statutory requirements, and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company's best estimates of the amount of consideration to which it is entitled based on the terms of the applicable contract. The amount of variable consideration may be constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Given the early stage of the Company’s commercial operations it has provided constraint of its variable consideration due to its potential consumption trends. Actual amounts of consideration ultimately received may differ from the Company's estimates. If actual results in the future vary from estimates, the Company adjusts these estimates, which would affect net product revenue and earnings in the period such variances become known.

Liabilities for co-pay assistance, expected product returns, rebates, and distributor fees are classified as “Other accrued liabilities” in the condensed balance sheets. Discounts, such as prompt pay discounts, and chargebacks are recorded as a reduction to trade accounts receivable, which is included in “Other prepaid and current assets” in the condensed balance sheets.

Forms of Variable Consideration

Rebates and Chargebacks: The Company estimates reductions to product sales for Public Health Service Institutions, such as Medicaid, Medicare and Veterans' Administration ("VA") programs, as well as certain other qualifying federal and state government programs, and other group purchasing organizations. The Company estimates these reductions based upon the Company's contracts with government agencies and other organizations, statutorily defined discounts and estimated payor mix. These organizations purchase directly from the Company's wholesalers at a discount and the wholesalers charge the Company back the difference between the wholesaler price and the discounted price. The Company's liability for Medicaid rebates consists of estimates for claims that a state will make for a current quarter. The Company's reserve for this discounted pricing is based on expected sales to qualified healthcare providers and the chargebacks that customers have already claimed.

Co-pay assistance: Eligible patients who have commercial insurance may receive assistance from the Company to reduce the patient's out of pocket costs. The Company will buy down the difference between the amount of the eligible patient's co-pay when the drug is purchased at the pharmacy at a determined price. Liabilities for co-pay assistance are calculated by actual program participation from third-party administrators.

Distribution Fees: The Company has written contracts with its customers that include terms for distribution fees and costs for inventory management. The Company estimates and records distribution fees due to its customers based on gross sales.

Product Returns: The Company generally offers a right of return based on the product’s expiration date and certain spoilage and damaged instances. The Company estimates the amount of product sales that may be returned and records the estimate as a reduction of product sales in the period the related product sales is recognized. The Company’s estimates for expected returns are based primarily on an ongoing analysis of sales information and visibility into the inventory remaining in the distribution channel.

10

Discounts: The Company provides product discounts, such as prompt pay discounts, to its customers. The Company estimates cash discounts based on terms in negotiated contracts and the Company’s expectations regarding future payment patterns.

Recently Implemented Accounting Pronouncements

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2016-13 which requires financial instruments to be recognized at an estimate of current expected credit losses. As part of the ASU, financial assets measured at amortized cost will be presented at the net amount expected to be collected. In addition, companies will recognize an allowance for credit losses on available-for-sale investments rather than reducing the amortized cost in an other-than-temporary impairment. The Company has chosen the practical expedient to exclude accrued interest from both the fair value and the amortized cost basis of available-for-sale debt securities in identifying and measuring an impairment. The Company adopted the standard on January 1, 2020. The adoption of this standard did not have a material impact on the Company's balance sheets, statements of operations or statements of cash flows.

In August 2018, the FASB issued ASU 2018-15 which includes provisions to clarify customer's accounting for implementation costs incurred in a cloud computing arrangement. Under the updated guidance, a customer in a cloud computing arrangement that is a service contract should follow the internal-use software guidance to determine how to account for costs incurred in implementation. The updated guidance also requires certain classification on the balance sheets, statements of operations and statements of cash flows as well as additional quantitative and qualitative disclosures. The Company adopted the standard effective January 1, 2020 and has chosen to adopt the standard prospectively. Implementation costs for cloud computing arrangements are capitalized in "Other prepaid and current assets" on the Company's balance sheets. The adoption of this standard did not have a material impact to the Company's balance sheets, statements of operations or statements of cash flows.

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, 2019.

3. Collaborations with Third Parties

DSE Agreement Terms

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 tablets 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 also is responsible to supply DSE with certain manufacturing supply of the API or bulk tablets. The Company is also eligible to receive a substantial additional regulatory milestone payment upon the grant of the marketing authorisation 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 “DSE JCC”). The DSE 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.

11

Agreement Terms Amendment

On June 18, 2020, the Company entered into an amendment to the license and collaboration agreement with DSE, dated as of January 2, 2019. In June, the Company completed the transfer of the MAAs for NILEMDO and NUSTENDI. Pursuant to the terms of the amendment, DSE paid the Company the second $150.0 million milestone based on completion of the NUSTENDI MAA transfer rather than the first product sale in the EU, as previously agreed. Additionally, the Company and DSE have agreed to expand the DSE Territory, or the territory in which DSE has exclusive commercialization rights to NILEMDO and NUSTENDI to include Turkey. DSE's designated affiliate in Turkey will be solely responsible, at its sole cost and expense, for all regulatory matters relating to such products in Turkey, including obtaining regulatory approval for such products in Turkey.

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. In the three and six months ended June 30, 2019, the Company recognized $1.0 million and $146.4 million of collaboration revenue, respectively. In the three and six months ended June 30, 2020, the Company recognized approximately $0.7 million and $1.6 million, respectively, related to the on-going performance obligation for the ongoing regulatory efforts related to the MAA in the DSE Territory, which was transferred to DSE in June 2020.

In addition, in the three and six months ended June 30, 2020, the Company recognized the $150.0 million milestone as collaboration revenue based on the successful transfer of the NUSTENDI MAA. In the three and six months ended June 30, 2020, the Company recognized collaboration revenue of $1.0 million related to the sales of bulk tablets of NILEMDO and NUSTENDI to DSE pursuant to the Supply Agreement that was executed with DSE.

All remaining 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 development activities, regulatory approvals and sales-based milestones. Additionally, the Company expects that any consideration related to royalties and sales-based milestones will be recognized when the subsequent sales occur.

Otsuka Agreement Terms

On April 17, 2020, the Company entered into the Otsuka Agreement with Otsuka. Pursuant to the Otsuka Agreement, the Company granted Otsuka exclusive development and commercialization rights to NEXLETOL and NEXLIZET in Japan. Otsuka will be responsible for all development, regulatory, and commercialization activities in Japan. In addition, Otsuka will fund all clinical development costs associated with the program in Japan.

Pursuant to the agreement, the consideration consists of a $60.0 million upfront cash payment and the Company will be eligible to receive additional payments of up to $450.0 million if certain regulatory and commercial milestones are achieved by Otsuka. The potential future milestone payments include up to $20.0 million upon first JNDA submissions in the Otsuka Territory, up to $70.0 million upon the first NHI Price Listing for NEXLETOL in the Otsuka Territory, and up to $50.0 million upon the achievement of the primary major adverse cardiovascular events (“MACE”) in the CLEAR Outcomes study and the CV risk reduction rate on the U.S. 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 up to $310.0 million related to total net sales achievements for Otsuka in Japan. Finally, the Company will receive tiered fifteen percent (15%) to thirty percent (30%) royalties on net sales in Japan.

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

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 development activities, regulatory approvals and sales-based milestones. 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. Inventories

Inventories as of June 30, 2020 and December 31, 2019 consist of the following (in thousands):

	June 30, 2020		December 31, 2019
Raw materials	$	4,961	$	—
Work in process		2,869		—

The Company has entered into a contract manufacturing agreement with a third party commercial manufacturing organization for the production of certain inventory supplies of NEXLETOL and NEXLIZET. The agreement has an initial term of three years and will renew automatically for successive periods of one year each unless terminated by either party. Under the agreement the Company is obligated to purchase minimum order commitments on a rolling twelve-month period for the batches of inventory supplies produced.

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 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.

13

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. On November 6, 2019, the court held a hearing on the motion to dismiss. On February 13, 2020, the court granted the motion to dismiss with prejudice and entered judgment in the Company’s favor. On March 16, 2020, the plaintiff filed a notice of appeal to the Supreme Court of Delaware. On June 1, 2020, the plaintiff filed his opening brief on appeal to the Supreme Court of Delaware. On July 1, 2020, the Company and the defendants filed an answering brief. 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.

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, 2019 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 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 that have been measured at fair value on a recurring basis:

Description	Total		Level 1		Level 2		Level 3
	(in thousands)
June 30, 2020
Assets:
Money market funds	$	287,632	$	287,632	$	—	$	—

8. Liability Related to the Revenue Interest Purchase Agreement

On June 26, 2019, the Company entered into a 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 tablets and other working capital needs. Pursuant to the RIPA, the Company received $125.0 million at closing, less certain issuance costs. The Company is also entitled to receive up to approximately $75.0 million in

15

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”). In March 2020, the Company received $25.0 million from Oberland upon receiving regulatory approval of NEXLETOL.

As consideration for such payments, the Purchasers have a right to receive certain revenue interests (the “Revenue Interests”) from the Company based upon net sales of the Company’s certain products which 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, as of June 30, 2020, the Company has recorded a liability, referred to as the “Revenue interest liability” in the condensed balance sheets, of $166.3 million, net of $0.5 million of capitalized issuance costs in connection with the RIPA. The Company imputes 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 net sales. The Company evaluates the interest rate quarterly based on its current net sales forecasts utilizing the prospective method.

A significant increase or decrease in net sales will materially impact the revenue interest liability, interest expense and the time period for repayment. The Company recorded approximately $4.6 million and $8.8 million in interest expense related to this arrangement for the three and six months ended June 30, 2020, respectively.

The Company received $125.0 million in exchange for entering into the RIPA and $25.0 million in March 2020 upon receiving regulatory approval of NEXLETOL. The effective annual imputed interest rate is 10.1%. The Company incurred $0.6 million of issuance costs in connection with the RIPA, which will be amortized to interest expense over the estimated term of the RIPA. Payments made to Oberland as a result of the Company’s net sales will reduce the revenue interest liability.

10. Stock Compensation

Employee Stock Purchase Plan

In April 2020, the board of directors approved the Esperion Therapeutics, Inc. 2020 Employee Stock Purchase Plan (the "ESPP") which was approved by the Company's shareholders on May 28, 2020. The ESPP allows eligible employees to authorize payroll deductions of up to 10% of their base salary or wages up to $25,000 annually to be applied toward the purchase of shares of the Company's common stock on the last trading day of the offering period. Participating employees will purchase shares of the Company's common stock at a discount of up to 15% on the lesser of the closing price of the Company's common stock on the NASDAQ Global Select Market (i) on the first trading day of the offering period or (ii) the last day of any offering period. Offering periods under the ESPP will generally be in six month increments, commencing on September 1 and March 1 of each calendar year with the administrator having the right to establish different offering periods.

Stock-based compensation related to RSUs was approximately $1.8 million and $3.3 million for the three and six months ended June 30, 2020, respectively, including $0.1 million and $0.1 million for the three and six months ended June 30, 2020, respectively, that were capitalized into inventory, and $0.4 million and $0.6 million for the three and six months ended June 30, 2019, respectively. As of June 30, 2020, there was $21.5 million of unrecognized stock-based compensation expense related to unvested RSUs, which will be recognized over a weighted-average period of 3.2 years.

11. Leases

The Company has operating leases primarily related to the Company’s principal executive office, automobile leases and other IT related equipment. The lease for the principal executive office has a lease term of 5 years and the automobile leases and IT equipment leases primarily have a term of 3 years. During the six months ended June 30, 2020, the right of use operating lease assets and operating lease liabilities recognized on the condensed balance sheet increased by $4.6 million and $4.6 million from December 31, 2019, respectively, due to the addition of automobile leases and IT equipment associated with the onboarding of the Company’s commercial salesforce to support the commercialization of NEXLETOL and NEXLIZET. During the three and six months ended June 30, 2020, the Company recognized $0.6 million and $0.8 million, respectively, of operating lease costs, recognized on the condensed statements of operations, and paid cash for the amounts included in the measurement of lease liabilities of $0.6 million and $0.8 million, respectively, which were included in operating cash flows on the condensed statements of cash flows. During the three and six months ended June 30, 2019, the Company recognized less than $0.1 million and $0.1 million, respectively, of operating lease costs, recognized on the condensed statements of operations, and paid cash for the amounts included in the measurement of lease liabilities of less than $0.1 million and $0.1 million, respectively, which were included in operating cash flows on the condensed statements of cash flows. At June 30, 2020, the weighted-average remaining lease term of operating leases was 2.7 years and the weighted average discount rate was 3.6%. There were 0 right-of-use assets obtained in exchange for lease obligations in the six months ended June 30, 2020 or 2019. The Company had no additional operating and finance leases that have not yet commenced as of June 30, 2020 or 2019.

12. Income Taxes

There was 0 provision for income taxes for the three and six months ended June 30, 2020 and 2019, because the Company has incurred annual operating losses since inception. At June 30, 2020, 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.

13. Net Income (Loss) Per Common Share

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net income per share is computed by dividing net income 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. For purposes of this calculation, stock options and unvested RSUs are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

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

	For the three months ended ,				For the six months ended ,
	June 30,		June 30,		June 30,		June 30,

Overview

Corporate Overview

We are the Lipid Management Company, a pharmaceutical company focused on developing and commercializing affordable, oral, once-daily, non-statin medicines 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 medicines that will make a substantial impact on reducing global cardiovascular disease, or CVD; the leading cause of death around the world. NEXLETOL® (bempedoic acid) and NEXLIZET^TM (bempedoic acid and ezetimibe) tablets are the first, oral, once-daily, non-statin LDL-C lowering medicines approved in the U.S. in nearly 20 years for patients with atherosclerotic cardiovascular disease, or ASCVD, or heterozygous familial hypercholesterolemia, or HeFH.

On February 21, 2020, we announced that the U.S. Food and Drug Administration, or FDA, approved NEXLETOL as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C. The effect of NEXLETOL on cardiovascular morbidity and mortality has not been determined. NEXLETOL is the first oral, once-daily, non-statin LDL-C lowering medicine approved since 2002 for indicated patients. NEXLETOL became commercially available on March 30, 2020.

21

On February 26, 2020, we announced that the FDA approved NEXLIZET as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C. The effect of NEXLIZET on cardiovascular morbidity and mortality has not been determined. NEXLIZET is the first non-statin, LDL-C lowering fixed combination drug product ever approved. NEXLIZET became commercially available on June 4, 2020.

On January 31, 2020, the Committee for Medicinal Products for Human Use, or CHMP, of the European Medicines Agency, or EMA, adopted a positive opinion for the Marketing Authorisation Applications, or MAAs, of both bempedoic acid and the bempedoic acid / ezetimibe combination tablets, recommending approval for the treatment of hypercholesterolemia and mixed dyslipidemia. On April 6, 2020, we announced that the European Commission, or EC, approved NILEMDO™ (bempedoic acid) and NUSTENDI™ (bempedoic acid and ezetimibe) tablets for the treatment of hypercholesterolemia and mixed dyslipidemia. The decision is applicable to all 27 European Union member states plus the United Kingdom, Iceland, Norway and Liechtenstein. NILEMDO (bempedoic acid) and NUSTENDI (bempedoic acid and ezetimibe) are the branded products names for bempedoic acid and the bempedoic acid / ezetimibe combination tablets in Europe. NILEMDO is the first, oral, non-statin, LDL-C lowering medicines approved in Europe in almost two decades for indicated patients, and NUSTENDI is the first non-statin, LDL-C lowering combination medicine ever approved in Europe.

On April 17, 2020, we entered into a license and collaboration agreement, or the Otsuka Agreement, with Otsuka Pharmaceutical Co., Ltd., or Otsuka. Pursuant to the Otsuka Agreement, we granted Otsuka exclusive development and commercialization rights to NEXLETOL and NEXLIZET in Japan. Otsuka will be responsible for all development, regulatory, and commercialization activities in Japan. In addition, Otsuka will fund all clinical development costs associated with the program in Japan. We estimate this amount to total up to $100 million over the next few years. We received an upfront cash payment of $60 million in April 2020 and will receive up to an additional $450 million in total development and sales milestones. We will also receive tiered royalties ranging from 15 percent to 30 percent on net sales in Japan.

On June 18, 2020, we entered into an amendment to the license and collaboration agreement, or LCA Amendment, with Daiichi Sankyo Europe GmbH, or DSE, dated as of January 2, 2019. In June 2020, we completed the transfer of the MAAs for NILEMDO and NUSTENDI. Pursuant to the terms of the amendment, DSE paid us the second $150 million milestone based on completion of the NUSTENDI MAA transfer rather than the first product sale in the EU, which is anticipated later this year. Prior to the execution of the LCA Amendment, the milestone payment was due upon the first commercial sale in Europe, which is anticipated later this year. Additionally, we and DSE have agreed to expand the territory in which DSE has exclusive commercialization rights to NILEMDO and NUSTENDI to include Turkey. DSE’s designated affiliate in Turkey will be solely responsible, at its sole cost and expense, for all regulatory matters relating to such products in Turkey, including obtaining Regulatory Approval for such product in Turkey.

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 tablets. In February 2020, the FDA approved NEXLETOL and NEXLIZET. NEXLETOL was commercially available in the U.S. on March 30, 2020 and NEXLIZET was commercially available in the U.S. on June 4, 2020. 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.

During the three and six months ended June 30, 2020, our net income was $124.6 million and $46.4 million, respectively, primarily due to revenue generated from our collaboration agreements with DSE and Otsuka. 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. All of our prior net losses resulted from costs incurred in connection with research and development programs and general and administrative costs 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:

●commercializing NEXLETOL and NEXLIZET tablets in the U.S.; and

● completing the clinical development activities for the CLEAR global cardiovascular outcomes trial, or CVOT.

22

Accordingly, we may need additional financing to support our continuing operations and further the development of our products. We may seek to fund our operations and further development activities through collaborations with third parties, strategic alliances, licensing arrangements, permitted debt financings, permitted royalty-based 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

NEXLETOL is a first-in-class ATP Citrate Lyase, or ACL, inhibitor that lowers LDL-C by reducing cholesterol biosynthesis and up-regulating the LDL receptors. Completed Phase 3 studies conducted in more than 3,000 patients, with over 2,000 patients treated with NEXLETOL, demonstrated an average 18 percent placebo corrected LDL-C lowering when used in patients on moderate or high-intensity statins. NEXLETOL was approved by the FDA in February 2020 as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C.

NEXLIZET contains bempedoic acid and ezetimibe and lowers elevated LDL-C through complementary mechanisms of action by inhibiting cholesterol synthesis in the liver and absorption in the intestine. Phase 3 data demonstrated NEXLIZET lowered LDL-C by a mean of 38 percent compared to placebo when added on to maximally tolerated statins. NEXLIZET was approved by the FDA in February 2020 as an adjunct to diet and maximally tolerated statin therapy for the treatment of adults with HeFH or established ASCVD who require additional lowering of LDL-C.

NILEMDO is a first-in-class ACL inhibitor that lowers LDL-C by reducing cholesterol biosynthesis and up-regulating the LDL receptors. NILEMDO was approved by the EC in March 2020 for use in adults with primary hypercholesterolemia (heterozygous familial and non-familial) or mixed dyslipidemia, as an adjunct to diet in combination with a statin or statin with other lipid-lowering therapies in adult patients unable to reach LDL-C goals with the maximum tolerated dose of a statin, or alone or in combination with other lipid-lowering therapies as an adjunct to diet in adult patients who are statin-intolerant, or for whom a statin is contraindicated.

NUSTENDI contains bempedoic acid and ezetimibe and lowers elevated LDL-C through complementary mechanisms of action by inhibiting cholesterol synthesis in the liver and absorption in the intestine. NUSTENDI was approved by the EC in March 2020 for use in adults with primary hypercholesterolemia (heterozygous familial and non-familial) or mixed dyslipidemia, as an adjunct to diet in combination with a statin in adult patients unable to reach LDL-C goals with the maximum tolerated dose of a statin in addition to ezetimibe, alone in patients who are either statin-intolerant or for whom a statin is contraindicated, and are unable to reach LDL-C goals with ezetimibe alone, or as an adjunct to diet in adult patients already being treated with the combination of bempedoic acid and ezetimibe as separate tablets with or without statin.

During the six months ended June 30, 2020, we incurred $33.6 million in expenses related to our CLEAR Outcomes CVOT and other ongoing clinical studies.

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.

Ongoing Clinical Studies

Global Cardiovascular Outcomes Trial—CLEAR Outcomes

CLEAR Outcomes is a Phase 3, event driven, randomized, multicenter, double-blind, placebo-controlled clinical study designed to evaluate whether treatment of bempedoic acid reduces the risk of cardiovascular events in patients with statin intolerance who have cardiovascular disease or are at high risk for cardiovascular disease. The primary endpoint of the study is the effect of bempedoic acid on major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization; also referred to as "four-component MACE"). CLEAR Outcomes is designed to provide 90 percent power to detect an approximately 15 percent relative risk reduction in the primary endpoint in the bempedoic acid treatment group as compared to the placebo group and is expected to complete with a minimum of 1,620 patients experiencing the primary endpoint.

23

The study over-enrolled with 14,032 patients with hypercholesterolemia and high cardiovascular disease risk at over 1,400 sites in 32 countries. Eligible patients at high risk (LDL-C >100 mg/dL in primary prevention) for cardiovascular disease or with cardiovascular disease (LDL-C between 100 mg/dL to 190 mg/dL in secondary prevention) and who are only able to tolerate less than the lowest approved daily starting dose of a statin and considered statin averse, were randomized to receive bempedoic acid 180 mg once-daily or placebo. The expected average baseline LDL-C level in all patients is between 135 mg/dL and 140 mg/dL.

CLEAR Outcomes will conclude once the predetermined number of MACE endpoints occur. We initiated CLEAR Outcomes in December 2016 and completed enrollment in August 2019. The expected average treatment duration will be 3.75 years with a minimum treatment duration of approximately 2.25 years. Based on estimated cardiovascular event rates, we expect to meet the target number of events in the second half of 2022. The study is intended to support our submissions for a CV risk reduction indication in the U.S., Europe and other territories.

The COVID-19 Pandemic

In March 2020, the World Health Organization declared the outbreak of a novel strain of coronavirus, or COVID-19, as a pandemic, which continues to spread throughout the United States and worldwide. We could be materially and adversely affected by the risks, or the public perception of the risks, related to an epidemic, pandemic, outbreak, or other public health crisis, such as the recent outbreak of COVID-19. We are monitoring the global outbreak and spread of COVID-19 and have taken steps to identify and mitigate the adverse impacts on, and risks to, our business posed by its spread and actions taken by governmental and health authorities to address the COVID-19 pandemic. The spread of COVID-19 has caused us to modify our business practices, including implementing a work-from-home policy for all employees who are able to perform their duties remotely and restricting all nonessential travel, and we expect to continue to take actions as may be required or recommended by government authorities or as we determine are in the best interests of our employees, the patients we serve and other business partners in light of COVID-19. Given the fluidity of the COVID-19 pandemic however, we do not yet know the full extent of the potential impact of COVID-19 on our business operations. The ultimate extent of the impact of any epidemic, pandemic, outbreak, or other public health crisis on our business, financial condition and results of operations will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of such epidemic, pandemic, outbreak, or other public health crisis and actions taken to contain or prevent the further spread, among others. Accordingly, we are unable to reliably estimate the extent to which our business, financial condition and results of operations will or has been affected, including any impacts on product sales or research and development expense. To date, we have not experienced any interruption of our supply of drug products needed to support our ongoing clinical study and product sales. We remain focused on maintaining a strong balance sheet, liquidity and financial flexibility and continue to monitor developments as we deal with the disruptions and uncertainties from a business and financial perspective relating to COVID-19. We will continue to work diligently with our partners and stakeholders to continue supporting patient access to our approved medicines, advancing our product under regulatory review as well as in our clinical studies to the extent safe to do so for patients, caregivers and healthcare practitioners, and ensuring the continuity of our manufacturing and supply chain. For additional information related to the potential impact of COVID-19 on our business, please read Part II-Item 1A, “Risk Factors” of this Quarterly Report on Form 10-Q.

Financial Operations Overview

Product sales, net

Product sales, net is related to our sales of NEXLETOL and NEXLIZET. NEXLETOL was commercially available in the U.S. on March 30, 2020 and NEXLIZET was commercially available in the U.S. on June 4, 2020

Collaboration revenue

Collaboration revenue is related to our collaboration agreements with DSE and Otsuka. Collaboration revenue in the three and six months ended June 30, 2020, was primarily related to the $150.0 million milestone from the MAA transfer to DSE and the $60.0 million from the upfront payment with Otsuka. In the three and six months ended June 30, 2019, collaboration revenue was primarily related to the initial recognition of the $150.0 million upfront payment from our collaboration agreement with DSE.

24

Cost of goods sold

Cost of goods sold is related to our net product sales of NEXLETOL and NEXLIZET and the cost of goods sold from our supply agreements with collaboration partners. Prior to the FDA approval of NEXLETOL and NEXLIZET, expenses associated with the manufacturing of our products were recorded as research and development expense.

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 tablets, 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 prior to product 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 tablets. 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.

We will continue to incur research and development expenses in the foreseeable future as they relate to our ongoing CLEAR Outcomes CVOT 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 tablets. The duration, costs and timing associated with the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablets will depend on a variety of factors, including uncertainties associated with the results of our clinical studies and our ability to obtain regulatory approval outside the U.S. and Europe. For example, if a regulatory authority were to require us to conduct clinical studies beyond 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 tablets, 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 tablets.

Selling, General and Administrative Expenses

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

We anticipate that our selling, general and administrative expenses will increase in the future in connection with the commercialization of NEXLETOL and NEXLIZET, 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.

25

Interest Expense

Interest expense is related to our Revenue Interest Purchase Agreement, or RIPA, with Eiger III SA LLC, or Oberland, an affiliate of Oberland Capital.

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.

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 our collaboration agreements and revenue interest liability. 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.

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, 2019. As we continue through fiscal year 2020, we expect that net product sales will become a critical accounting estimate.

Collaboration Revenue

Collaboration revenue recognized for the three months ended June 30, 2020 was $211.6 million compared to $1.0 million for the three months ended June 30, 2019, an increase of $210.6 million. The increase in collaboration revenue was primarily related to the $60.0 million upfront payment from the collaboration with Otsuka and $150.0 million of collaboration revenue from DSE related to the MAA transfer milestone.

Cost of goods sold

Cost of goods sold for the three months ended June 30, 2020 was $0.4 million, primarily related to cost of goods sold from our supply agreements with collaboration partners and our net product sales of NEXLETOL and NEXLIZET. NEXLIZET was commercially available in the U.S. on June 4, 2020.

Research and development expenses

Research and development expenses for the three months ended June 30, 2020, were $35.0 million, compared to $42.8 million for the three months ended June 30, 2019, a decrease of $7.8 million. The decrease in research and development expenses was primarily attributable to a decline in costs related to the completion of enrollment of our CLEAR CVOT, which was fully enrolled during the third quarter of 2019.

Selling, general and administrative expenses

Selling, general and administrative expenses for the three months ended June 30, 2020, were $47.7 million, compared to $13.5 million for the three months ended June 30, 2019, an increase of $34.2 million. The increase in selling, general and administrative expenses was primarily attributable to costs to support the commercialization of NEXLETOL and NEXLIZET in the U.S., increases in our headcount resulting from the buildout of our approximately 300-member customer-facing team, stock-based compensation expense, and other costs to support our growth.

Interest Expense

Interest expense for the three months ended June 30, 2020, was $4.6 million. Interest expense was related to our RIPA with Oberland, which was entered into on June 26, 2019.

Other income, net

Other income, net for the three months ended June 30, 2020, was $0.1 million, compared to $1.1 million for the three months ended June 30, 2019, a decrease of $1.0 million. The decrease is related to lower interest income on our investments due to lower interest rates.

Collaboration Revenue

Collaboration revenue recognized from our collaboration agreements for the six months ended June 30, 2020 was $212.6 million compared to $146.4 million for the six months ended June 30, 2019, an increase of $66.2 million. Revenue for the six months ended June 30, 2020 was primarily attributable to $150.0 million for the milestone related to the MAA transfer to DSE and the $60.0 million for the upfront payment in the Otsuka collaboration agreement signed on April 17, 2020. Revenue for the six months ended June 30, 2019 was attributable to the initial recognition of the upfront payment from our DSE collaboration agreement signed on January 2, 2019.

Cost of goods sold

Cost of goods sold for the six months ended June 30, 2020 was $0.4 million, primarily related cost of goods sold from our supply agreements with collaboration partners and our net product sales of NEXLETOL and NEXLIZET.

Research and development expenses

Research and development expenses for the six months ended June 30, 2020, were $69.7 million, compared to $89.1 million for the six months ended June 30, 2019, a decrease of $19.4 million. The decrease in research and development expenses was primarily attributable to a decline in costs related to the completion of enrollment of our CLEAR CVOT, which was fully enrolled during the third quarter of 2019, and a decline in costs related to our regulatory submission activities completed in 2019.

Selling, general and administrative expenses

Selling, general and administrative expenses for the six months ended June 30, 2020, were $89.2 million, compared to $25.7 million for the six months ended June 30, 2019, an increase of approximately $63.5 million. The increase in selling, general and administrative expenses was primarily attributable to costs to support the commercialization of NEXLETOL and NEXLIZET in the U.S., increases in our headcount resulting from the buildout of our approximately 300-member customer-facing team, stock-based compensation expense, and other costs to support our growth.

28

Interest Expense

Interest expense for the six months ended June 30, 2020, was $8.8 million. Interest expense was related to our RIPA with Oberland.

Other income, net

Other income, net for the six months ended June 30, 2020, was $0.4 million, compared to $1.5 million for the six months ended June 30, 2019, a decrease of $1.1 million. The decrease is related to lower interest income on our investments due to lower interest rates.

Liquidity and Capital Resources

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 a cash payment of $150.0 million upon the MAA transfer in June 2020 and are eligible for substantial additional sales and regulatory milestone payments and royalties. Pursuant to the RIPA with Oberland, we received an upfront cash payment of $124.4 million, net of issuance costs, and received an additional $25.0 million upon regulatory approval of NEXLETOL. We are eligible for an additional $50.0 million at our option upon reaching certain net product sales thresholds. In return, Oberland will have a right to receive revenue interests based on net product sales of our products. Pursuant to the license and collaboration agreement with Otsuka signed on April 17, 2020, we received an upfront cash payment of $60.0 million in April 2020 and are eligible for substantial additional development and sales milestone payments and royalties. We anticipate that we will incur losses for the foreseeable future.

As of June 30, 2020, our primary sources of liquidity were our cash and cash equivalents and available-for-sale investments, which totaled $298.5 million and $2.2 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,
	2020		2019
	(in thousands)
Cash provided by operating activities	$	70,044	$	37,682
Cash provided by investing activities		31,699		72,412
Cash provided by financing activities		29,688		128,205
Net increase in cash and cash equivalents	$	131,431	$	238,299

Operating Activities

We have incurred and expect to continue to incur, significant costs related to the commercialization of NEXLETOL and NEXLIZET and related to ongoing research and development, regulatory and other clinical study costs associated with the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablets.

Net cash provided by operating activities totaled $70.0 million for the six months ended June 30, 2020, consisting of the $150.0 million milestone for the MAA transfer from our collaboration agreement with DSE, $60.0 million from the Otsuka collaboration agreement and net product sales of NEXLETOL and NEXLIZET offset by cash used to fund the commercialization activities of NEXLETOL and NEXLIZET and the research and development costs related to bempedoic acid and the bempedoic acid / ezetimibe combination tablets, adjusted for non-cash expenses such as stock-based compensation expense, interest expense related to our RIPA with Oberland, depreciation and amortization and changes in working capital. Net cash provided by operating activities totaled $37.7 million for the 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 tablets, adjusted for non-cash expenses such as stock-based compensation expense, depreciation and amortization and changes in working capital.

29

Investing Activities

Net cash provided by investing activities of $31.7 million and $72.4 million for the six months ended June 30, 2020 and 2019, 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 $29.7 million for the six months ended June 30, 2020 related primarily to the cash received from the RIPA with Oberland upon regulatory approval of NEXLETOL. 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.

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 and commercial launch activities associated with NEXLETOL and NEXLIZET in the U.S. Pursuant to the license and collaboration agreement with DSE, we received an upfront cash payment of $150.0 million from DSE in the first quarter of 2019, $150.0 million in June 2020 upon transfer to DSE of MMA for NUSTENDI and are eligible for substantial additional sales and regulatory milestone payments and royalties. Pursuant to the RIPA with Oberland, we received an upfront cash payment of $125.0 million and received $25.0 million upon regulatory approval of NEXLETOL. We are eligible for an additional $50.0 million at our option upon reaching certain net product sales thresholds. In return, Oberland will have a right to receive revenue interest payments from us based on net product sales of certain of our products. Pursuant to the license and collaboration agreement with Otsuka, we received an upfront cash payment of $60.0 million from Otsuka in April 2020 and are eligible for substantial additional development and sales milestone payments and royalties. We estimate that current cash resources and proceeds to be received in the future for product sales, under the DSE and Otsuka collaboration agreements and the RIPA with Oberland are sufficient to fund operations through the commercialization of NEXLETOL and NEXLIZET. 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. We may need to secure additional cash resources to continue to fund the commercialization and further development of bempedoic acid and the bempedoic acid / ezetimibe combination tablets. Because of the numerous risks and uncertainties associated with the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablets 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 tablets, 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 tablets. Our future funding requirements will depend on many factors, including, but not limited to:

● our ability to successfully develop and commercialize NEXLETOL and NEXLIZET 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 tablets;

● the time and cost necessary to obtain regulatory approvals for bempedoic acid and the bempedoic acid / ezetimibe combination tablets in other territories outside the U.S. and Europe;

● 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.

30

Until such time, if ever, as we can generate U.S. substantial product sales, 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 arrangements with DSE and Otsuka 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, 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 tablets 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 issuance costs, and, subject to the terms and conditions of the RIPA, we received $25.0 million in March 2020 upon regulatory approval of NEXLETOL. We are eligible for an additional $50.0 million at our option upon reaching certain product sales thresholds. As consideration for the payments, Oberland has the right to receive certain revenue interests from us based on the net product sales of certain products, which will be tiered payments initially ranging from 2.5% to 7.5% of our net product 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 condensed balance sheets and are accounting for the RIPA under the effective-interest method over the estimated life of the RIPA. Per the terms of the agreement, every $100 million of net sales generated, less than or equal to $250 million in an annual aggregate, would result in a repayment obligation of approximately $7.5 million at the stated repayment rate in the first year. In the future, as net sales thresholds set forth in the agreement are met and the repayment percentage rate changes, the amount of the obligation and timing of payment is likely to change. A significant increase or decrease in net sales will materially impact the revenue interest liability, interest expense and the time period for repayment. Refer to Note 8 “Liability Related to the Revenue Interest Purchase Agreement” in the Notes to the Condensed Financial Statements for further information.

We have entered into a contract manufacturing agreement with a third party commercial manufacturing organization for the production of certain inventory supplies of NEXLETOL and NEXLIZET. The agreement has an initial term of three years and will renew automatically for successive periods of one year each unless terminated by either party. Under the agreement we are obligated to purchase minimum order commitments on a rolling twelve-month period for the batches of inventory supplies produced.

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, 2019.

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

There have been no material changes with respect to the information appearing in Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 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, 2020, 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, 2020, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the three months ended June 30, 2020, in connection with the approval of NEXLETOL and NEXLIZET and commercial availability of NEXLETOL, we implemented new procedures and controls around our net product sales and inventory processes.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

The information required with respect to this item can be found under “Commitments and Contingencies” in Note 5 to our condensed financial statements included elsewhere in this Form 10-Q and is incorporated by reference into this Item 1.

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 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, 2019 and in all of the other information included or incorporated in this report. 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, 2019. 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.

The outbreak of the novel strain of coronavirus, SARS-CoV-2, or similar public health crises, could have a material adverse impact on our business, financial condition and results of operations, including our commercial launch of NEXLETOL and NEXLIZET, our intended commercial launch of NILEMDO and NUSTENDI lead by DSE in the EU, our ongoing CLEAR Outcomes trial, and operations and sales in general.

In December 2019, a novel strain of coronavirus, SARS-CoV-2, which causes coronavirus disease 2019 (COVID-19), surfaced in Wuhan, China. Since then, SARS-CoV-2 and COVID-19 have spread to multiple countries, including the United States. The COVID-19 pandemic is evolving, and to date has led to the implementation of various responses, including government-imposed quarantines, travel restrictions and other public health safety measures. In response to the spread of SARS-CoV-2 and COVID-19, our commercial and medical organizations are following internal guidelines and respective state guidelines when interacting with physicians and customers.

As a result of the COVID-19 outbreak, or similar pandemics, we may experience disruptions that could severely impact our business, including our clinical development and commercialization plans for the bempedoic acid and bempedoic acid / ezetimibe fixed dose combination tablets. As a result of the current pandemic, or future pandemics, we may not be able to meet expectations with respect to the net product sales of NEXLETOL, NEXLIZET, NILEMDO and NUSTENDI or attain or maintain profitability and positive cash-flow from operations. Our ongoing clinical trial for bempedoic acid tablet and the timing for the review and approval of expanded indications for their effect on cardiovascular events may be impacted as well. Business interruptions from the current or future pandemics may also adversely impact the third parties we solely rely on to sufficiently manufacture NEXLETOL, NEXLIZET, NILEMDO and NUSTENDI and to produce our product candidates in quantities we require, which may impair the commercialization of NEXLETOL, NEXLIZET, NILEMDO and NUSTENDI and our research and development activities. So far, most of our manufacturing partners and CROs have continued to produce at anticipated levels despite these challenges.

33

Some factors from the COVID-19 outbreak that may delay or otherwise adversely affect our business generally, and the third parties which we rely upon, include business disruptions caused by potential workplace, laboratory and office closures and an increased reliance on employees working from home, disruptions to or delays in ongoing laboratory experiments and operations, staffing shortages, travel limitations or mass transit disruptions, any of which could adversely impact our business operations or delay necessary interactions with local regulators, ethics committees and other important agencies and contractors.

The COVID-19 outbreak continues to rapidly evolve. The extent to which the outbreak impacts our business, including our commercial results and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and actions to contain the outbreak or treat its impact, such as social distancing and quarantines or lock-downs in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.
