Insights

Esperion grows revenue, adds debt-backed deals, and agrees to a cash-and-CVR buyout.

Q1 2026 revenue rose to $80.1M, with product sales of $43.4M and collaboration revenue of $36.7M. The net loss improved to $25.2M, helped by higher royalties from partners such as Daiichi Sankyo Europe and Otsuka.

The balance sheet shows $156.2M in cash but significant obligations: a royalty sale liability of $291.2M and term and convertible debt exceeding $250M. Additional Athyrium term loans of $25M and a new $50M Otsuka royalty sale deepen reliance on future partnered sales.

Strategically, Esperion is expanding its cardiovascular portfolio via the $75M Corstasis acquisition plus up to $180M in milestones. The pending merger with Essence Parent offers $3.16 per share in cash plus CVRs linked to up to $100M in milestone payments, with closing targeted in Q3 2026 subject to stockholder approval.

Royalty sale liability financial
"As of March 31, 2026, the Company has recorded a liability, referred to as the “Royalty sale liability”"
contingent value right financial
"one contractual contingent value right per share, representing the right to participate in contingent payments"
A contingent value right is a special security that gives its holder the right to receive one or more future payments only if specified events happen, such as a product reaching a sales target or getting regulatory approval. It matters to investors because it offers potential extra payout tied to uncertain outcomes—like a bet that a project will succeed—so it can add upside to a deal while also carrying extra risk and valuation uncertainty.
Abbreviated New Drug Application regulatory
"had filed an Abbreviated New Drug Application ("ANDA") with the FDA seeking approval of a generic version"
An abbreviated new drug application is a regulatory submission used to gain approval to market a generic version of an already approved prescription medicine by showing it is equivalent in effect and safety to the original product, without repeating full clinical trials. For investors, an approval signals a lower-cost competitor entering the market that can quickly capture sales from the branded drug, similar to a generic knock‑off replacing a name‑brand item on store shelves.
CLEAR Outcomes study medical
"achievement of the primary major adverse cardiovascular events (“MACE”) endpoint in the CLEAR Outcomes study"
Employee Stock Purchase Plan financial
"the Esperion Therapeutics, Inc. 2020 Employee Stock Purchase Plan (as amended, the "ESPP")"
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

1. The Company and Basis of Presentation
Esperion Therapeutics, Inc. ("the Company” or "Esperion") is a commercial stage biopharmaceutical company currently focused on bringing new medicines to patients that address unmet medical needs. The Company has developed and is commercializing U.S. Food and Drug Administration (“FDA”) approved oral, once-daily, non-statin medicines for patients who are at risk for cardiovascular disease ("CVD") and are struggling with elevated low density lipoprotein cholesterol ("LDL-C"). Through commercial execution, product acquisitions, international partnerships and collaborations, and advancement of its pre-clinical pipeline, the Company continues to evolve into a leading global biopharmaceutical company.

The Company's lead products, NEXLETOL® (bempedoic acid) tablets and NEXLIZET® (bempedoic acid and ezetimibe) tablets, are oral, once-daily, non-statin medicines indicated to reduce the risk of myocardial infarction and coronary revascularization in adults who are unable or unwilling to take recommended statin therapy (including those not taking a statin) with established CVD, or at high risk for a CVD event but without established CVD, and to reduce LDL-C in adults with primary hyperlipidemia. The Company's products were approved by the FDA, the European Commission ("EC") (which, with respect to the UK, has been converted to a UK marketing authorization) and Swiss Agency for Therapeutic Products ("Swissmedic") in 2020. The FDA approved expanded indications for NEXLETOL and NEXLIZET tablets in March 2024. The EC approved expanded indications for NILEMDO® (bempedoic acid) tablets and NUSTENDI® (bempedoic acid and ezetimibe) tablets in May 2024. Otsuka Pharmaceutical Co., Ltd ("Otsuka"), Esperion’s Japanese collaborator, received approval from the Japanese Ministry of Health, Labour and Welfare to market NEXLETOL as a treatment for hypercholesterolemia and familial hypercholesterolemia in September 2025, with National Health Insurance ("NHI") pricing received in the fourth quarter of 2025. The Company filed supplemental NDAs for product approvals in Canada in November 2024, with NEXLETOL approval received in the fourth quarter of 2025 and NEXLIZET approval expected in the first half of 2026. The Company's collaboration partners filed in Israel in March 2025, with expected approval in the first half of 2026, and in Australia in July 2025, with expected approval in the fourth quarter of 2026.

On March 2, 2026, the Company entered into an Agreement and Plan of Merger (the “Corstasis Merger Agreement”) with Corstasis Therapeutics Inc., a Delaware corporation (“Corstasis”), Cirrus Transaction Subsidiary, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”) and certain other parties described therein. Pursuant to the Corstasis Merger Agreement, on April 2, 2026, the Company completed the merger of Corstasis with and into Merger Sub, with Corstasis surviving the merger as a wholly owned subsidiary of the Company (the “Corstasis Merger”). The aggregate up-front consideration for the transactions contemplated by the Corstasis Merger Agreement (the “Transactions”) was $75,000,000 in cash, subject to customary adjustments and a post-closing purchase price adjustment. In addition to the upfront cash consideration, the former equityholders of Corstasis are entitled to receive: (i) milestone payments up to an aggregate amount equal to $180,000,000 if certain regulatory approval or commercial sales milestones are achieved and (ii) royalty and licensing-revenue-derived payments in connection with the Company’s (or its sublicensees’) future sales of certain products. Corstasis, the developer and commercial sponsor of Enbumyst, was a privately held, commercial-stage biopharmaceutical company focused on therapies for the treatment of edema associated with cardiovascular, hepatic, and renal disease. Through the acquisition of Corstasis, the Company expanded its cardiovascular portfolio with Enbumyst (bumetanide nasal spray), the first and only FDA-approved nasal spray loop diuretic. Enbumyst received FDA approval in September 2025 for the treatment of edema associated with congestive heart failure, as well as hepatic and renal disease in adults. Refer to Note 16, "Subsequent Events" for further information.

On May 1, 2026, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Essence Parent Inc., a Delaware corporation (“Parent”), and Essence MergerCo Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“MergerCo”), pursuant to which, subject to the terms and conditions thereof, MergerCo will merge with and into the Company, with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent (the “Merger”). Subject to the terms and conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.001 per share, of the Company (the “Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock (i) owned by Parent or MergerCo, (ii) owned by the Company as treasury shares or (iii) held by any person who properly exercises appraisal rights under Delaware law), will be converted into the right to receive (A) an amount in cash equal to $3.16 per share, without interest (the “Per Share Cash Consideration”), plus (B) one contractual contingent value right per share, representing the right to participate in contingent payments in cash, without interest, upon the achievement of certain milestones as set forth in the Contingent Value Rights Agreement (the “CVR Agreement”), on the terms and subject to the conditions set forth in the Merger Agreement and the CVR Agreement (the “CVR” and, together with the Per Share Cash Consideration, the “Merger Consideration”). Each CVR will entitle the holder to its pro rata share, in cash, of contingent payments of up to an additional $100,000,000 in the aggregate, without interest and less any applicable tax withholding, upon the achievement of specified milestones during the applicable milestone periods as set forth in the CVR Agreement. Consummation of the Merger is subject to the approval of the Company’s stockholders and other customary closing conditions. The Merger has not closed as of the

Table of Contents
date these condensed interim financial statements were issued and is expected to close in the third quarter of 2026. Accordingly, the accompanying condensed interim financial statements do not reflect the Merger or any related effects. Refer to Note 16, "Subsequent Events" for further information.

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, raising capital, and commercializing its products. 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; successfully manage relationships with its collaboration partners; expand and successfully manage 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 immediate future. While management believes current cash resources and future cash received from the Company's net product sales and collaboration agreements with Daiichi Sankyo Europe GmbH ("DSE"), Otsuka, and Daiichi Sankyo Co. Ltd ("DS"), and other partners, entered into on January 2, 2019, April 17, 2020 and April 26, 2021, respectively, 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 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, 2025, and the notes thereto, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. 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 GAAP 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.
Segment Reporting
The Company views its operations and manages its business in one operating segment, which is the business of researching, developing and commercializing therapies for the treatment of patients with elevated LDL-C.
Cash and Cash Equivalents
The Company invests its excess cash in bank deposits, money market accounts, and short-term investments. The Company considers all highly liquid investments with an original maturity of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents are reported at fair value.
8

Table of Contents
Fair Value of Financial Instruments
The Company’s cash and cash equivalents are carried at fair value. Financial instruments, including accounts receivable, other prepaid and current assets, accounts payable and accrued liabilities are carried at cost, which approximates fair value. Debt is carried at amortized cost, which approximates fair value.
Concentration of Credit Risk
The Company enters into a limited number of distribution agreements with distributors and specialty pharmacies for NEXLETOL and NEXLIZET. The Company's net product sales are with these customers. As of March 31, 2026 and December 31, 2025, nine customers accounted for all of the Company's net trade receivables. As of March 31, 2026 and December 31, 2025, three customers held approximately 99% and 98%, respectively, of the Company's trade receivables associated with net product sales. For the three months ended March 31, 2026 and 2025, three customers accounted for approximately 97% and 99%, respectively, of gross sales of NEXLETOL and NEXLIZET.
Revenue Recognition
In accordance with ASC 606, Revenue from Contracts with Customers ("ASC 606"), 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, including royalties, of the Company's product candidates by the Company's partners and product sales consists of sales of NEXLETOL and NEXLIZET in the United States.
a.Collaboration Revenue
The Company has entered into agreements 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 as 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, through its third party contract manufacturing partners, may manufacture and supply quantities of active pharmaceutical ingredient (“API”), finished goods or bulk tablets reasonably required by collaboration partners for the
9

Table of Contents
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 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 collaborators.

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. On March 22, 2024, the Company announced that the FDA approved new label expansions for NEXLETOL and NEXLIZET based on positive CLEAR Outcomes data that include indications for cardiovascular risk reduction and expanded LDL-C lowering in both primary and secondary prevention patients. In addition, the enhanced labels support the use of NEXLETOL and NEXLIZET either alone or in combination with statins. They also include new indications for primary hyperlipidemia, alone or in combination with a statin. Product sales, net totaled $43.4 million for the three months ended March 31, 2026 and $34.9 million for the three months ended March 31, 2025.

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 “Accrued variable consideration” in the condensed balance sheets. Discounts, such as prompt pay discounts, and chargebacks are recorded as a reduction to accounts receivable 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.
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.
Inventories, net
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 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 goods sold in the period in which they are incurred.
Prepaid Inventory Costs
Prepaid inventory costs represent advance payments made by the Company to third‑party suppliers and contract manufacturers for raw materials and other inventory‑related costs for which the Company has not yet taken ownership of the materials. Prepaid inventory costs are recorded at cost, which approximates fair value, or using standard cost, and are reclassified to inventory when the related materials ownership transfers to the Company.

Liability Related to the Sale of Future Royalties
The Company treats the sale of future DSE royalties as debt, amortized under the effective interest rate method over the estimated life of the royalty sale agreement. The royalty sale liability is presented net of deferred issuance costs on the condensed balance sheets. The amortization of the liability related to future royalties and related interest expense are based on the Company's current estimates of future royalties, which the Company determines by using forecasted royalty sales from its collaboration partner, historical experience, third-party forecasts and current market conditions. The Company periodically assesses the forecasted sales and to the extent the amount or timing of future estimated royalty payments is materially different than previous estimates, the Company will account for any such change by adjusting the liability related to the sale of future royalties and prospectively recognize the related non-cash interest expense. Royalty revenue is recognized and the related liability reduced as earned.
Recently Issued Accounting Pronouncements
In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40), which requires additional disclosure of the nature of expenses included in the income statement. The primary goal is to improve the decision usefulness of expense information on public business entities' income statements through the disaggregation of relevant expense captions in the notes of the financial statements. This ASU will be effective for annual periods beginning after December 15, 2026, and interim periods after December 15, 2027. The Company is currently evaluating the timing and impacts of adoption of this ASU.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which amends certain aspects of the accounting for and disclosure of software costs. This ASU will be effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the timing and impacts of adoption of this ASU.

3. Collaborations with Third Parties
DSE Agreement Terms
On January 2, 2019, the Company entered into a license and collaboration agreement with DSE, which was amended on June 18, 2020, and further amended on January 2, 2024 (as amended, the “DSE Agreement”). Pursuant to the DSE Agreement, the Company granted DSE exclusive commercialization rights to bempedoic acid and the bempedoic acid / ezetimibe combination tablet in the European Economic Area, United Kingdom, Turkey, and Switzerland (collectively, the “DSE Territory”). DSE is responsible for commercialization in the DSE Territory. 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. The Company remains responsible for clinical development, regulatory and manufacturing activities for the licensed products globally, including in the DSE Territory outside of Turkey.

Pursuant to the DSE Agreement, the Company received upfront cash of $150.0 million in 2019 and a $150.0 million cash milestone payment in 2020 following the completion of the NUSTENDI Marketing Authorisation Applications ("MAA"). The Company is responsible for supplying DSE with certain manufacturing supply of the API or bulk tablets. 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 is entitled to receive tiered fifteen percent (15%) to twenty-five percent (25%) royalties on net DSE Territory sales.

The DSE 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.
On January 2, 2024, the Company entered into a settlement agreement (the "Settlement Agreement") with DSE to amicably resolve and dismiss their commercial dispute in the Southern District of New York. Under the Settlement Agreement, DSE has agreed to pay the Company an aggregate of $125.0 million, including (1) a $100.0 million payment within 15 business days of the effective date of the Settlement Agreement and (2) a $25.0 million payment in the calendar quarter immediately following the calendar quarter in which the EMA renders a decision on the application that was filed with the EMA for a Type II(a) variation for the Company’s oral non-statin products marketed as NILEMDO (bempedoic acid) tablets and NUSTENDI (bempedoic acid and ezetimibe) tablets in Europe. Pursuant to the Settlement Agreement, also on January 2, 2024, the Company entered into a 3rd Amendment (the “DSE Amendment”) to the License and Collaboration Agreement dated January 2, 2019 with DSE. The DSE Amendment grants DSE the exclusive rights for clinical development, regulatory activities, manufacture and commercialization of a bempedoic acid/ezetimibe/statin triple combination pill in the DSE Territory. Further, after a transition period, DSE will assume sole responsibility for the manufacture of NILEMDO and NUSTENDI for the DSE Territory. As of January 2, 2024, DSE has sole authority and control of regulatory communications with the EMA regarding the pending marketing authorization applications for NILEMDO and NUSTENDI. Pursuant to the DSE Amendment, the Company is entitled to receive one-time cash payments of up to $300.0 million upon the achievement of certain commercial milestones related to total net sales achievements in the DSE Territory. The Company is also entitled to receive tiered 15% to 25% royalties on net DSE Territory sales.

Collaboration Revenue
In the three months ended March 31, 2026 and 2025, the Company recognized collaboration revenue of approximately $32.7 million and $29.4 million, respectively, related to royalty revenue from DSE from the sales of NILEMDO and NUSTENDI, as well as the sales of bulk tablets and API 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 sales-based milestones. Additionally, the Company expects that any consideration related to sales-based milestones will be recognized when the subsequent sales occur.

Otsuka Agreement Terms
On April 17, 2020, the Company entered into a license and collaboration agreement (the "Otsuka Agreement") with Otsuka, which was further amended on November 5, 2025. Pursuant to the Otsuka Agreement, the Company granted Otsuka exclusive development and commercialization rights to NEXLETOL and NEXLIZET in Japan (the "Otsuka Territory"). 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 Otsuka 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.

In the three months ended March 31, 2026, the Company recognized collaboration revenue of $2.1 million related to royalty revenue from Otsuka and sales of bulk tablets to Otsuka pursuant to the supply agreement that was executed with Otsuka. In the three months ended March 31, 2025, the Company did not have any collaboration revenue related to the Otsuka Agreement.
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.
DS Agreement Terms
In April 2021, the Company entered into a license and collaboration agreement with DS (the "DS Agreement"). Pursuant to the DS Agreement, the Company granted DS exclusive rights to develop and commercialize bempedoic acid and the bempedoic acid / ezetimibe combination tablet in South Korea, Taiwan, Hong Kong, Thailand, Vietnam, Brazil, Macao, Cambodia and Myanmar (collectively, the "DS Territory"). In October 2025, DS terminated their rights to sell bempedoic acid and the bempedoic acid / ezetimibe combination tablet in Cambodia and Myanmar. The DS Agreement allows for potential expansion across geographies including Saudi Arabia, Kuwait, Oman, UAE, Qatar, Bahrain, Yemen, Colombia and other Latin American countries. Except for certain development activities in South Korea and Taiwan, DS will be responsible for development and commercialization in these territories. In addition, DS will fund all development costs associated with the program in the DS Territory. Pursuant to the DS Agreement, the consideration consists of a $30.0 million upfront cash payment that is non-refundable, non-reimbursable and non-creditable.

Increases in prepaid inventory costs year over year are primarily driven by the timing of supplier purchases relative to the consumption of active pharmaceutical ingredient (“API”), as well as increased advance purchases to support expected demand.
5. Commitments and Contingencies
ANDA Litigation

Starting in March 2024, the Company received notices from nine pharmaceutical companies, six of which filed exclusively with respect to NEXLETOL and four of which filed with respect to NEXLETOL and NEXLIZET (each, an “ANDA Filer”), notifying the Company that each company had filed an Abbreviated New Drug Application ("ANDA") with the FDA seeking approval of a generic version of NEXLETOL and/or NEXLIZET in the United States, as applicable. The ANDAs each contained Paragraph IV certifications alleging that certain of the Company’s Orange Book listed patents covering NEXLETOL or NEXLIZET, as applicable, are invalid and/or will not be infringed by each ANDA Filer’s manufacture, use or sale of the medicine for which the ANDA was submitted.

Under the Hatch-Waxman Act to the Federal Food, Drug, and Cosmetic Act ("FDCA"), the Company had 45 days from receipt of the notice letters to commence patent infringement lawsuits against these generic drug manufacturers in a federal district court to trigger a stay precluding the FDA’s approval of any ANDA from being effective any earlier than 7.5 years from the date of approval of the NEXLETOL or NEXLIZET, as applicable, new drug application or entry of judgment holding the patents invalid, unenforceable, or not infringed, whichever occurs first.

Beginning in May 2024, the Company filed patent infringement lawsuits under the Hatch-Waxman Act in the United States District Court, District of New Jersey, against each ANDA Filer: Accord Healthcare Inc.; Alkem Laboratories Ltd.; Aurobindo Pharma Limited (along with its affiliate); Dr. Reddy’s Laboratories Inc. (along with its affiliate, collectively, “Dr. Reddy’s Laboratories”); Hetero USA Inc. (along with its affiliates, collectively, “Hetero USA”); Micro Labs USA Inc. (along with its affiliate, collectively, “Micro Labs”); MSN Pharmaceuticals Inc. (along with an affiliate); Renata Limited (“Renata”); and

Table of Contents
Sandoz Inc. The Company’s complaints allege that by filing the applicable ANDA, such ANDA Filer has infringed NEXLETOL’s and/or NEXLIZET’s Orange Book patents, as applicable, included in its Paragraph IV certifications, and seek an injunction preventing the FDA from granting final approval of the ANDA before the expiration of the asserted patents, and a permanent injunction to prevent the ANDA Filer from commercializing a generic version of NEXLETOL and/or NEXLIZET, as applicable, until the expiration of the asserted patents.

The Company subsequently reached settlement agreements with Micro Labs, Hetero USA, Accord Healthcare Inc., Dr. Reddy’s Laboratories, and Alkem Laboratories Ltd. in May 2025, June 2025, July 2025, October 2025 and February 2026, respectively. Each settlement agreement resolved the patent litigation brought by the Company against the particular ANDA Filer, each of which has agreed not to market a generic version of NEXLETOL and/or NEXLIZET, as applicable, in the United States prior to April 19, 2040, unless certain circumstances customarily included in these types of agreements occur. With the settlement with Dr. Reddy’s Laboratories in October 2025, there are no remaining challenges regarding the validity or infringement of U.S Patent No. 7,335,799 in the pending patent litigation with the remaining ANDA filers. Certain of the Company’s patents that remain subject to the pending patent litigation are scheduled to expire in March 2036, while others are scheduled to expire in June 2040.

The pending patent litigation against the remaining ANDA Filers (Aurobindo Pharma Limited (along with an affiliate); MSN Pharmaceuticals Inc. (along with an affiliate); Renata (along with an affiliate); and Sandoz Inc.) is ongoing, and there can be no assurance whether such ongoing patent litigation will allow a generic version of NEXLETOL and/or NEXLIZET, as applicable, to be marketed in the U.S. prior to April 19, 2040. The trial is anticipated to begin no earlier than January 2027, but no trial date has been set.

In January 2026, Renata notified the Company that it had filed an ANDA with the FDA seeking approval of a generic version of NEXLIZET in the United States (the “2026 Renata ANDA”). The 2026 Renata ANDA is in addition to the ANDA that Renata had previously filed with respect to NEXLETOL, for which the pending patent litigation described above is ongoing. Under the Hatch-Waxman Act, the Company had 45 days from receipt of the 2026 Renata ANDA notice letter to commence patent infringement lawsuits against Renata in a federal district court to trigger a stay precluding the FDA’s approval of the 2026 Renata ANDA from being effective any earlier than 7.5 years from the date of approval of the NEXLIZET new drug application or entry of judgment holding the patents invalid, unenforceable, or not infringed, whichever occurs first. In March 2026, the Company filed a patent infringement lawsuit under the Hatch-Waxman Act in the United States District Court, District of New Jersey, against Renata. The Company’s complaint alleges that by filing the 2026 Renata ANDA, Renata has infringed NEXLIZET’s Orange Book patents included in its Paragraph IV certifications, and seeks an injunction preventing the FDA from granting final approval of the 2026 Renata ANDA before the expiration of the asserted patents, and a permanent injunction to prevent Renata from commercializing a generic version of NEXLIZET until the expiration of the asserted patents. No trial date has been set.

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 (in thousands):

There were no transfers between Levels 1, 2 or 3 during the three months ended March 31, 2026 and 2025.
8. Sale of Future Royalties
On June 27, 2024, the Company entered into the Purchase Agreement with OCM IP Healthcare Portfolio LP ("the Purchaser"). Pursuant to the Purchase Agreement, the Company sold to the Purchaser, and the Purchaser purchased for $304.7 million, a portion of the royalties payable on net sales of Bempedoic Acid (as defined in the License and Collaboration Agreement) and any other Licensed Products (as defined in the License and Collaboration Agreement) in the DSE Territory (as defined in the License and Collaboration Agreement) pursuant to the License and Collaboration Agreement dated January 2, 2019, between Daiichi Sankyo Europe GMBH and the Company, as amended (the “License and Collaboration Agreement” and such royalties being the “Royalty Interests”). In connection with the Purchase Agreement, the Company incurred $9.6 million in issuance costs.

The Purchaser acquired 100% of the Royalty Interests until such time as the Purchaser has received an aggregate amount equal to 1.7x of the Purchase Price (equivalent to $517.9 million). Following receipt of such amount, 100% of all Royalty Interests will revert to the Company. The Purchase Agreement contains other customary terms and conditions, including representations and warranties, covenants and indemnification obligations in favor of each party.

The Company evaluated the arrangement and determined that the proceeds from the sale of future royalties should be treated as a debt instrument according to ASC 470 Debt. The Company imputes interest expense associated with the liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the liability to be repaid in full over the anticipated life of the arrangement. The interest rate on the liability may vary during the term of the
16

Table of Contents
agreement depending on a number of factors, including the level and timing of forecasted royalty sales. The Company evaluates the interest rate quarterly based on its expectations of forecasted royalty sales from its license partner, historical experience, third-party forecasts and current market conditions utilizing the prospective method. A significant increase or decrease in future royalty sales will materially impact the royalty sale liability, interest expense and the time period for repayment. The repayment of the royalty sale liability to the Purchaser does not have a fixed repayment schedule. Rather, it will be completely repaid and extinguished when the Company has repaid an aggregate amount equal to 1.7x of the Purchase Price. The $9.6 million in issuance costs will be amortized through interest expense over the life of the agreement. Royalties are remitted to the Purchaser in the subsequent quarter from when it's earned. The Company recognizes those royalties in accounts receivable, net and accounts payable on the condensed balance sheets until the royalties are remitted to the Purchaser from DSE.

As of March 31, 2026, the Company has recorded a liability, referred to as the “Royalty sale liability” on the condensed balance sheets, of $291.2 million, net of $6.2 million of capitalized issuance costs in connection with the royalty sale liability, which will be amortized to interest expense over the estimated term, $2.1 million of which will be amortized over the next 12 months and $4.1 million thereafter. As of December 31, 2025, the Company had recorded a liability of $295.8 million, net of $6.8 million of capitalized issuance costs, in connection with the royalty sale liability. The Company currently expects to repay $80.7 million in the next twelve months.

The Company recorded $13.9 million and $13.1 million in interest expense related to this arrangement for the three months ended March 31, 2026 and 2025, respectively, which included approximately $0.6 million and $0.4 million, respectively, of amortized issuance costs.
The effective annual imputed interest rate is 1.4% as of March 31, 2026 and 1.6% as of December 31, 2025.
The following table summarizes the royalty sale liability activity during the three months ended March 31, 2026 and 2025:

9. Debt
Credit Agreement
On December 13, 2024, the Company entered into a credit agreement (the “Credit Agreement”) with GLAS USA LLC, as administrative agent, and Athyrium Opportunities IV Co-Invest 1 LP, HCR Stafford Fund II, L.P., HCR Potomac Fund II, L.P. and HCRX Investments HoldCo, L.P., as the initial lenders party thereto. The Credit Agreement provides for a $150.0 million term loan (the “Loan”), which was borrowed in full at closing. Proceeds from the Loan were used to repay a portion of the outstanding obligations under the Company’s existing $265.0 million aggregate principal amount 4.00% Convertible Senior Subordinated Notes due November 2025 and to pay fees and expenses in connection with the Credit Agreement.

The Loan will bear interest at an annual rate of 9.75% if paid in cash, and 11.75% if paid-in-kind. At the Company’s option, interest on the Loan may be paid-in-kind for the first four full fiscal quarters ending after the closing date. The Company elected to have interest on the Loan paid-in-kind for the second quarter ended June 30, 2025 and for the third quarter ended September 30, 2025. The Credit Agreement requires quarterly interest-only payments for the first four years after the closing date and, thereafter, the Loan will partially amortize in quarterly principal payments of 12.50%, with the outstanding balance to be repaid on the maturity date, which shall be five (5) years after the closing date (the “Maturity Date”); provided that, such amortization may be adjusted pursuant to the terms of the Credit Agreement. The Company may, at its option, prepay the Loan in whole or in part at any time, subject to concurrent payment of certain fees and, if prepaid (a) within the first two years after closing, a make-whole premium plus 3%, (b) after the second anniversary of closing and on or prior to the third anniversary, a prepayment premium of 3% and (c) after the third anniversary of closing and on or prior to the fourth anniversary, a prepayment premium of 1% (the “Prepayment Premium”). The Loan is subject to mandatory prepayment in the
17

Table of Contents
event of specified asset dispositions, extraordinary receipts, unpermitted debt issuances, change of control, and, in certain circumstances, failure to settle the exchanges of the Company’s Existing Notes, subject to certain exceptions and thresholds and concurrent payment of certain fees and, if prepaid within the first four years of closing, the applicable Prepayment Premium.

All obligations under the Credit Agreement shall be guaranteed by the Company’s present and future wholly owned subsidiaries, subject to customary exceptions, and secured by assets of Company and the guarantors, including the equity interests in the Company’s subsidiaries, subject to customary exceptions. The Credit Agreement contains a financial covenant to maintain minimum liquidity of $50.0 million. The Credit Agreement contains affirmative and negative covenants customary for a senior secured loan. The negative covenants under the Credit Agreement limit the ability of the Company and its subsidiaries to, among other things, dispose of assets, engage in mergers, acquisitions, and similar transactions, incur additional indebtedness, grant liens, make investments, pay dividends or make distributions or certain other restricted payments in respect of equity, prepay other indebtedness, enter into restrictive agreements, undertake fundamental changes or amend certain material contracts, in each case subject to certain exceptions.

The Credit Agreement also contains certain customary events of default, including, but not limited to, a failure to comply with the covenants in the Credit Agreement. If an event of default has occurred and continues beyond any applicable cure period, the administrative agent or the required lenders may accelerate all outstanding obligations under the Credit Agreement and/or exercise any other remedies provided under the loan documents.

In connection with the borrowing of the Loan, the Company incurred 2.5% of original issue discount ("OID"), or approximately $3.8 million. In addition, the Company incurred debt issuance costs of $5.4 million in connection with the borrowing of the Loan. Both the OID and debt issuance costs were capitalized and included in long-term debt on the condensed balance sheets at the inception of the Loan, and are being amortized to interest expense using the effective interest method over the same term. As the Company elected to have interest on the loan paid-in-kind for the quarter ended June 30, 2025 and for the quarter ended September 30, 2025, $9.1 million was added to the principal balance of the Loan. As of March 31, 2026, the Company recognized $152.7 million of long-term debt related to the Credit Agreement on the condensed balance sheets, net of the remaining unamortized discount and debt issuance costs associated with the Loan of $2.6 million and approximately $3.8 million, respectively. As of December 31, 2025, the Company recognized $152.2 million of long-term debt related to the Credit Agreement on the condensed balance sheets, net of the remaining unamortized discount and debt issuance costs associated with the Loan of $2.8 million and approximately $4.1 million, respectively. During the three months ended March 31, 2026, the Company recognized approximately $4.3 million of interest expense, including $0.5 million of OID and debt issuance costs amortization. During the three months ended March 31, 2025, the Company recognized $4.1 million of interest expense, including $0.5 million of OID and debt issuance costs amortization.

2025 Notes
In November 2020, the Company issued $280.0 million aggregate principal amount of 4.0% senior subordinated convertible notes due November 2025. The net proceeds the Company received from the offering was approximately $271.1 million, after deducting the initial purchasers’ discounts and commissions and offering expenses payable by the Company (the “2025 Notes”). The 2025 Notes were the Company's senior unsecured obligations and matured on November 15, 2025 (the “Maturity Date”). The 2025 Notes were convertible into shares of the Company’s common stock, and could have been repurchased for cash, or a combination thereof, at the Company’s election, at an initial conversion rate of 30.2151 shares of common stock per $1,000 principal amount of the 2025 Notes, which is equivalent to an initial conversion price of approximately $33.096 per share of common stock, subject to adjustment. The Company paid interest on the 2025 Notes semi-annually in arrears on May 15 and November 15 of each year.

On October 22, 2021, the Company entered into a privately negotiated exchange agreement (the “2021 Exchange Agreement”) with two co-managed holders (the “Holders”) of its 2025 Notes. Under the terms of the 2021 Exchange Agreement the Holders agreed to exchange (the “2021 Exchange”) with the Company $15.0 million aggregate principal amount of the Convertible Notes held in the aggregate by them (and accrued interest thereon) for shares of the Company’s common stock. Pursuant to the 2021 Exchange Agreement, the number of shares of common stock to be issued by the Company to the Holders upon consummation of the 2021 Exchange was determined based upon the volume-weighted-average-price per share of common stock, subject to a floor of $5.62 per share, during the five trading-day averaging period, commencing on the trading day immediately following the date of the 2021 Exchange Agreement. The 2021 Exchange closed on November 3, 2021 with 1,094,848 shares of the Company's common stock being exchanged.

On December 12, 2024, the Company entered into privately negotiated exchange and subscription agreements with certain holders of its 4.00% Convertible Senior Subordinated Notes due 2025 (the “2025 Notes”) pursuant to which the Company issued $100.0 million aggregate principal amount of 5.75% Convertible Senior Subordinated Notes due in June 2030 (the “2030 Notes”) consisting of (a) approximately $57.5 million principal amount of 2030 Notes, along with approximately
18

Table of Contents
$153.4 million in cash, including accrued interest, issued in exchange for approximately $210.1 million principal amount of 2025 Notes (the “Exchange Transaction”). The Company also issued and sold approximately $42.5 million aggregate principal amount of 2030 Notes for cash, pursuant to privately negotiated agreements (the “Subscription Transactions” and, together with the Exchange Transaction, the “Transaction”). The Exchange Transaction closed on December 17, 2024 under an Indenture between the Company and U.S. Bank Trust Company, National Association, as trustee. In exchange for issuing the 2030 Notes pursuant to the Exchange Transaction, the Company received and cancelled the exchanged 2025 Notes.

In November 2025, the Company repaid the 2025 notes in full for $54.9 million. As of December 31, 2025, no principal amount or unamortized debt discount and issuance costs remained on the balance sheet.

The Company recorded $0.6 million of interest expense during the three months ended March 31, 2025, relating to the cash interest on the 2025 Notes due semi-annually and including the amortization of the debt issuance costs of $0.1 million.

2030 Notes

As noted above, the Company issued $100.0 million aggregate principal amount of 5.75% Convertible Senior Subordinated Notes due 2030 (the “2030 Notes”) on December 17, 2024. The Company incurred approximately $3.3 million of issuance costs associated with the 2030 Notes.
The 2030 Notes mature on June 15, 2030, unless earlier converted, redeemed or repurchased. The 2030 Notes are the Company’s senior unsecured obligations and will pay interest on the 2030 Notes at an annual rate of 5.75% payable in cash semiannually in arrears on June 15 and December 15 of each year, beginning June 15, 2025. Before March 15, 2030, holders of the 2030 Notes will have the right to convert their notes only upon the occurrence of certain events. From and after March 15, 2030, holders may convert their notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will have the right to elect to settle conversions by paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock. The initial conversion rate is 326.7974 shares of common stock per $1,000 principal amount of notes, which represents an initial conversion price of approximately $3.06 per share of common stock. The conversion rate and conversion price will be subject to adjustment upon the occurrence of certain events. The indenture governing the 2030 Notes includes certain restrictive covenants that limit the Company’s ability to incur additional indebtedness, subject to certain exceptions.

The 2030 Notes will be redeemable, in whole or in part, for cash at the Company’s option at any time, and from time to time, on or after December 20, 2027 and prior to the forty-first (41st) scheduled trading day immediately before the maturity date, but only if the last reported sale price per share exceeds 130% of the conversion price for a specified period of time and certain other conditions are satisfied. The redemption price will be equal to the principal amount of the 2030 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

In addition, if the Company undergoes a “fundamental change” (as defined in the Indenture), subject to certain conditions, holders may require the Company to repurchase for cash all or part of their 2030 Notes in principal amounts of $1,000 or an integral multiple thereof. The repurchase price will be equal to the principal amount of the 2030 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

The Indenture provides for customary events of default, including payment defaults, breaches of covenants, failure to pay certain judgments and certain events of bankruptcy, insolvency and reorganization. If an event of default occurs and is continuing, the principal amount of the 2030 Notes, plus accrued and unpaid interest, if any, may be declared immediately due and payable, subject to certain conditions set forth in the Indenture. These amounts automatically become due and payable if an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs.

As of March 31, 2026, the principal amount of 2030 Notes was $100.0 million, and the unamortized debt issuance costs were $2.6 million, for a net carrying amount of $97.4 million. As of December 31, 2025, the principal amount of 2030 Notes was $100.0 million, and the unamortized debt issuance costs were $2.7 million, for a net carrying amount of $97.3 million.

The Company recorded $1.6 million of interest expense during the three months ended March 31, 2026 relating to the cash interest on the 2030 Notes due semi-annually and including amortization of the debt issuance costs of $0.1 million. The Company recorded $1.6 million of interest expense during the three months ended March 31, 2025 relating to the cash interest on the 2030 notes due semi-annually and including amortization of the debt issuance costs of $0.1 million.

As of March 31, 2026, no 2030 Notes were convertible pursuant to their terms. The estimated fair value of the 2030 Notes was $122.1 million as of March 31, 2026 and $145.3 million as of December 31, 2025. The estimated fair value of the 2030

Notes was determined through consideration of quoted market prices. As of March 31, 2026, the if-converted value of the 2030 Notes did not exceed the principal value of those notes.

2022 Stock Option and Incentive Plan
In April 2022, the Company’s board of directors (the “Board”) approved the Esperion Therapeutics, Inc. 2022 Stock Option and Incentive Plan (as amended, the “2022 Plan”), which was approved by the Company's stockholders in May 2022. The number of shares of Common Stock available for awards under the 2022 Plan was set to 4,400,000, with any shares underlying awards that are forfeited, canceled, held back upon exercise of an option or settlement of an award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance or shares, or otherwise terminated (other than by exercise) under the 2022 Plan may be added back to the shares of Common Stock available for issuance under the 2022 Plan. The 2022 Plan provides for the award of stock options (both incentive and non-qualified options), stock appreciation rights, restricted stock, restricted stock units ("RSUs"), unrestricted stock, cash-based awards, and dividend equivalent rights. Following the approval of the 2022 Plan, no further awards will be issued under the Company’s Amended and Restated 2013 Stock Option and Incentive Plan (the “2013 Plan”).

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 Common Stock on the last trading day of the offering period. Participating employees will purchase shares of Common Stock at a discount of up to 15% on the lesser of the closing price of Common Stock on the NASDAQ Global 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 months increments, commencing on September 1 and March 1 of each calendar year with the administrator having the right to establish different offering periods. In April 2024, the Board approved a second amendment to the ESPP, which was approved by the Company's stockholders in May 2024, which increased the number of shares of Common Stock reserved for future issuance under the ESPP by an additional 6,175,000 shares. During the three months ended March 31, 2026 and 2025, the Company recognized $0.1 million and $0.1 million respectively, of stock compensation expense related to the ESPP. As of March 31, 2026, there have been 1,566,114 shares issued and 5,433,886 shares reserved for future issuance under the ESPP.

2017 Inducement Equity Plan

The actual number of units (if any) received under these awards will depend on continued employment and actual performance over the performance period. Each quarter, the Company updates their assessment of the probability that the performance milestone will be achieved. The Company amortizes the fair value of the PBSOs based on the expected performance period to achieve the performance milestone. The performance criteria was met in three months ended March 31, 2024.

12. Income Taxes
There was no provision for income taxes for the three months ended March 31, 2026 and 2025, because the Company has incurred annual operating losses since inception. At March 31, 2026, 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. Segment Reporting

The Company has one reportable segment. The majority of the Company's business consists of researching, developing and commercializing therapies for the treatment of patients with elevated LDL-C. The segment derives net product sales through sale of its NEXLETOL and NEXLIZET tablets to customers in the United States and through collaboration agreements with other third party companies to develop, manufacture and commercialize its products outside the United States. Net product sales were $43.4 million and $34.9 million for the three months ended March 31, 2026 and 2025, respectively. Collaboration revenue, which includes milestone payments, royalty revenues and sales of the Company's tablets to its collaboration partners, was $36.7 million and $30.1 million for the three months ended March 31, 2026 and 2025, respectively. During the three months ended March 31, 2026 and 2025, collaboration revenue was primarily derived in Europe and Japan from the Company's partners, DSE and Otsuka. The Company manages the business activities on a consolidated basis. The accounting policies of the segment are the same as those described in Note 2 “Summary of Significant Accounting Policies."

The Company's chief operating decision maker is the Chief Executive Officer ("CODM"). The CODM assesses the performance of the Company and decides how to allocate resources based on revenues and net (loss) income, which is reported on the condensed statements of operations. The chief operating decision maker also assesses performance by reviewing net cash (used in) provided by operating expenses, which is reported on the condensed statements of cash flows. The measure of segment assets is reported on the condensed balance sheets as total assets. The chief operating decision maker also reviews cash and cash equivalents. A significant component of the CODM's decision-making process is to ensure a balanced investment in research and development, as well as commercial activities to drive near-term success and sustain for the long term.

14. Stockholders' Deficit

Offering

On October 7, 2025, the Company entered into an Underwriting Agreement (the “2025 Underwriting Agreement”) with Piper Sandler & Co. and Cantor Fitzgerald & Co., as representative of the several underwriters (collectively, the “2025 Underwriters”), related to an underwritten public offering (the “2025 Offering”) of 30,000,000 shares (the “2025 Underwritten Shares”) of the Company’s Common Stock, at a public offering price of $2.50 per share. In addition, under the terms of the 2025 Underwriting Agreement, the underwriters were granted a 30-day option to purchase up to an additional 4,500,000 shares of Common Stock, at the public offering price. On October 10, 2025, the 2025 Underwriters gave notice to the Company of their partial election to exercise the underwriters' option to purchase 1,065,000 additional shares, which closed on October 14, 2025. Giving effect to the partial exercise of the underwriters' option, the Company issued an aggregate of 31,065,000 shares of Common Stock in the 2025 Offering, with net proceeds to the Company of approximately $72.6 million, after deducting the underwriting discount and offering expenses of approximately $5.1 million.
Warrants

In connection with an underwriting agreement with H.C. Wainwright & Co., LLC ("Wainwright") on December 2, 2021, (the "December 2021 Offering"), the Company issued warrants to purchase 36,964,286 shares of Common Stock at an exercise price of $9.00 and an expiration date of December 7, 2023. The warrants were recorded at fair value of $61.9 million to additional-paid-in-capital in accordance with ASC 815-10 based upon the allocation of the proceeds between the shares of Common Stock issued with the December 2021 Offering and the warrants. On December 7, 2023, 27,940,074 of these warrants expired. The remaining 9,024,212 warrants were amended as described below.

Registered Direct Offering and Warrant Amendment

On March 19, 2023, the Company entered into a purchase agreement (the "2023 Purchase Agreement") with the Purchasers named therein (the "Purchasers") pursuant to which the Company agreed to issue and sell, in a registered direct offering (the "Registered Direct Offering"), 12,205,000 shares of Common Stock, pre-funded warrants ("Pre-Funded Warrants") to purchase up to an aggregate of 20,965,747 shares of Common Stock in lieu of shares of Common Stock, and warrants ("Warrants") to purchase up to 33,170,747 shares of Common Stock. The combined purchase price of each share of Common Stock and accompanying Warrant is $1.675 per share. The Warrants expire on September 22, 2026 and have an exercise price of $1.55. The purchase price of each Pre-Funded Warrant is $1.674 (equal to the combined purchase price per share of Common Stock and accompanying Warrant, minus $0.001). The 2023 Purchase Agreement contains customary representations, warranties, covenants and indemnification rights and obligations of the Company and the Purchasers. The Registered Direct Offering closed on March 22, 2023. The Warrants and Pre-Funded Warrants were recorded at fair value of $22.8 million to additional-paid-in-capital in accordance with ASC 815-10 based upon the allocation of the proceeds between the shares of Common Stock issued with the Registered Direct Offering and the Warrants and Pre-Funded Warrants. The Company estimated the fair value of the Warrants using a Black-Scholes option-pricing model, which is based, in part, upon subjective assumptions including but

Table of Contents
not limited to stock price volatility, the expected life of the warrant, the risk-free interest rate and the fair value of Common Stock underlying the warrant. The Company estimates the volatility based on its historical volatility that is in line with the expected remaining life of the Warrants. The risk-free interest rate is based on the U.S. Treasury daily rate for a maturity similar to the expected remaining life of the Warrants. The expected remaining life of the Warrants is assumed to be equivalent to its remaining contractual term. The Company estimated the fair value of the Pre-Funded Warrants based on the market price of Common Stock at issuance.

In connection with the Registered Direct Offering, the Company amended, pursuant to Warrant Amendment Agreements, certain existing warrants to purchase up to an aggregate of 9,024,212 shares of Common Stock that were previously issued in December 2021 at an exercise price of $9.00 per share and had an expiration date of December 7, 2023, effective upon the closing of the Registered Direct Offering, such that the amended warrants have a reduced exercise price of $1.55 per share and expire three and one half years following the closing of the Registered Direct Offering, or September 22, 2026, for additional consideration of $0.125 per amended warrant. Based on the change in the fair value of the amended warrants, the Company recorded issuance costs to additional paid-in capital of $2.9 million.

The Company received gross proceeds of approximately $55.5 million from the Registered Direct Offering, before deducting placement agent fees and related offering expenses. The net proceeds to the Company from the Registered Direct Offering, after deducting the placement agent fees and expenses and the Company’s offering expenses of $4.2 million, were approximately $51.3 million. In addition, the Company received approximately $1.2 million as the gross consideration in connection with the Warrant Amendment Agreements. The net proceeds of the Warrant Amendment Agreements after deducting placement fees of $0.1 million were approximately $1.1 million.

As of March 31, 2026, no Pre-Funded Warrants were outstanding. During the three months ended March 31, 2026, 11,250,000 warrants were exercised. During the three months ended March 31, 2025, no warrants were exercised. As of March 31, 2026 and December 31, 2025, the Company had 7,642,700 and 18,892,700 of outstanding warrants related to the Warrant Amendment Agreements and Purchase Agreement, respectively, at a weighted average exercise price of $1.55 and an expiration date of September 22, 2026.


15. Net Loss Per Common Share
Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common stock equivalents outstanding for the period, including shares that potentially could be dilutive if they were exercised or vested during the period, determined using the treasury-stock method and the if-converted method for shares issuable upon conversion of convertible notes. For purposes of this calculation, warrants for common stock, stock options, PBSOs, unvested RSUs, shares issuable under the ESPP and shares issuable upon conversion of the convertible notes 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 shares outstanding at the end of the respective periods presented below were excluded from the calculation of diluted net loss per share due to their anti-dilutive effect:

On April 2, 2026 (the “Closing Date”), the Company entered into the Amendment to the Credit Agreement, by and among the Company, as the borrower, the lenders party thereto and Administrative Agent. The First Amendment amends that certain Credit Agreement, by and among the Company, the Administrative Agent and the lenders party thereto. The Amendment, among other things, provides for the incurrence of additional term loans in an aggregate principal amount of $25,000,000 (the “First Amendment Term Loans”), to be used, among other things, to finance a portion of the acquisition of Corstasis (as defined below). Amounts available under the First Amendment Term Loans were borrowed in full on the Closing Date. The First Amendment Term Loans bear the same terms as the outstanding term loans under the Existing Credit Agreement.
On the Closing Date, the Company entered into a Royalty Purchase Agreement (the “Purchase Agreement”) with Athyrium Opportunities IV Acquisition LP, a limited partnership formed under the laws of the State of Delaware (the “Purchaser”). Pursuant to the Purchase Agreement, the Company sold to the Purchaser, and the Purchaser purchased for $50,000,000, a portion of the royalties payable to the Company on net sales of Bempedoic Acid (as defined in the License and Collaboration Agreement) and any other Licensed Products (as defined in the License and Collaboration Agreement) in the Otsuka Territory (as defined in the License and Collaboration Agreement), and of the regulatory and commercial milestones payable, in each case, pursuant to the License and Collaboration Agreement dated as of April 17, 2020, between Otsuka Pharmaceutical Co., Ltd., a corporation organized and existing under the laws of Japan, and the Company, as amended (the “License and Collaboration Agreement” and such payments, the “Receivables”). The Purchaser acquired 100% of the Receivables until such time as the Purchaser receives an aggregate amount equal to $100,000,000. Following receipt of such amount, 100% of all Receivables will revert to the Company. The Purchase Agreement contains other customary terms and conditions, including representations and warranties, covenants and indemnification obligations in favor of each party.
On March 2, 2026, the Company entered into the Corstasis Merger Agreement with Corstasis, Cirrus Transaction Subsidiary, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”) and certain other parties described therein. Pursuant to the Corstasis Merger Agreement, on April 2, 2026, the Company completed the Corstasis Merger. The aggregate up-front consideration for the Transactions was $75,000,000 in cash, subject to customary adjustments and a post-closing purchase price adjustment. In addition, the equityholders of Corstasis are entitled to receive: (i) milestone payments up to an aggregate amount equal to $180,000,000 if certain regulatory approval or commercial sales milestones are achieved and (ii) royalty and licensing-revenue-derived payments in connection with the Company’s (or its sublicensees’) future sales of certain products. The Company has not completed its assessment of the accounting for the Corstasis Merger as either an asset acquisition or business combination, as the Company is still in the process of obtaining historical financial information from Corstasis, and gathering the information needed to perform significance evaluations under Regulation S‑X Article 11.
On May 1, 2026, the Company entered into the Merger Agreement with Parent and MergerCo, pursuant to which, subject to the terms and conditions thereof, MergerCo will merge with and into the Company with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent. Subject to the terms and conditions set forth in the Merger Agreement, at the Effective Time, each share of the Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock (i) owned by Parent or MergerCo, (ii) owned by the Company as treasury shares or (iii) held by any person who properly exercises appraisal rights under Delaware law), will be converted into the right to receive (A) the Per Share Cash Consideration, plus (B) one contractual contingent value right per share, representing the right to participate in contingent payments in cash, without interest, upon the achievement of certain milestones as set forth in the CVR Agreement, on the terms and subject to the conditions set forth in the Merger Agreement and the CVR Agreement. Each CVR will entitle the holder to its pro rata share, in cash, of contingent payments of up to an additional $100,000,000 in the aggregate, without interest and less any applicable tax withholding, upon the achievement of specified milestones during the applicable milestone periods as set forth in the CVR Agreement.
Consummation of the Merger is subject to the approval of the Company’s stockholders and other customary closing conditions, including, without limitation, (i) the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the receipt of certain non-U.S. antitrust approval, (ii) the absence of legal restraints prohibiting the Merger, (iii) the accuracy of the other party’s representations and warranties, subject to certain customary materiality qualifications set forth in the Merger Agreement, (iv) the other party’s compliance in all material respects with its obligations under the Merger Agreement, and (v) no Material Adverse Effect (as defined in the Merger Agreement) with respect to the Company having occurred since the date of the Merger Agreement that is continuing. The Merger Agreement contains certain termination rights for the Company and Parent. Upon termination of the Merger Agreement, (i) Parent, under specified circumstances, including termination by the Company because Parent fails to consummate the Merger when required by the Merger Agreement, will be required to pay the Company a termination fee in the amount of $68,309,078; and (ii) the Company, under specified circumstances, including termination by the Company in order to enter into an acquisition agreement providing for a Superior Proposal, will be required to pay Parent a termination fee in the

Overview
Corporate Overview
We are a commercial stage biopharmaceutical company currently focused on bringing new medicines to patients that address unmet medical needs. We have developed and are commercializing U.S. Food and Drug Administration, or FDA, approved oral, once-daily, non-statin medicines for patients who are at risk for cardiovascular disease, or CVD, and are struggling with elevated low-density lipoprotein cholesterol, or LDL-C. Through commercial execution, product acquisitions, international partnerships and collaborations, and advancement of our pre-clinical pipeline, we continue to evolve into a leading global biopharmaceutical company.

Our lead products NEXLETOL® (bempedoic acid) tablets and NEXLIZET® (bempedoic acid and ezetimibe) tablets are oral, once-daily, non-statin medicines indicated to reduce the risk of myocardial infarction and coronary revascularization in adults who are unable or unwilling to take recommended statin therapy (including those not taking a statin) with established

CVD, or at high risk for a CVD event but without established CVD, and to reduce LDL-C in adults with primary hyperlipidemia. Our products were approved by the FDA, the European Commission, or EC (which, with respect to the UK, has been converted to a UK marketing authorization), and Swiss Agency for Therapeutic Products, or Swissmedic in 2020. The FDA approved expanded indications for NEXLETOL and NEXLIZET tablets in March 2024. The EC approved expanded indications for NILEMDO® (bempedoic acid) tablets and NUSTENDI® (bempedoic acid and ezetimibe) tablets in May 2024. Otsuka Pharmaceutical Co., Ltd., or Otsuka, our Japanese collaborator, received approval from the Japanese Ministry of Health, Labour and Welfare to market NEXLETOL as a treatment for hypercholesterolemia and familial hypercholesterolemia in September 2025, with National Health Insurance, or NHI, pricing received in the fourth quarter of 2025. We filed supplemental NDAs for product approvals in Canada in November 2024, with NEXLETOL approval in the fourth quarter of 2025 and NEXLIZET approval expected in first half of 2026. Our collaboration partners filed in Israel in March 2025, with expected approval in the first half of 2026, and in Australia in July 2025, with expected approval in the fourth quarter of 2026.

On March 2, 2026, we entered into the Corstasis Merger Agreement with Corstasis, Merger Sub and certain other parties described therein. Pursuant to the Corstasis Merger Agreement, on April 2, 2026, we completed the Corstasis Merger. The aggregate up-front consideration for the Transactions was $75,000,000 in cash, subject to customary adjustments and a post-closing purchase price adjustment. In addition, the equityholders of Corstasis are entitled to receive: (i) milestone payments up to an aggregate amount equal to $180,000,000 if certain regulatory approval or commercial sales milestones are achieved and (ii) royalty and licensing-revenue-derived payments in connection with the Company’s (or its sublicensees’) future sales of certain products. Through this acquisition, the Company has acquired Corstasis, the developer and commercial sponsor of Enbumyst, the first and only FDA-approved nasal spray loop diuretic. Enbumyst received FDA approval in September 2025 for the treatment of edema associated with congestive heart failure, as well as hepatic and renal disease in adults.

On May 1, 2026, we entered into the Merger Agreement with Parent and MergerCo, pursuant to which, subject to the terms and conditions thereof, MergerCo will merge with and into the Company with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent. Subject to the terms and conditions set forth in the Merger Agreement, at the Effective Time, each share of the Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock (i) owned by Parent or MergerCo, (ii) owned by the Company as treasury shares or (iii) held by any person who properly exercises appraisal rights under Delaware law), will be converted into the right to receive (A) the Per Share Cash Consideration, plus (B) one contractual contingent value right per share, representing the right to participate in contingent payments in cash, without interest, upon the achievement of certain milestones as set forth in the CVR Agreement, on the terms and subject to the conditions set forth in the Merger Agreement and the CVR Agreement. Each CVR will entitle the holder to its pro rata share, in cash, of contingent payments of up to an additional $100,000,000 in the aggregate, without interest and less any applicable tax withholding, upon the achievement of specified milestones during the applicable milestone periods as set forth in the CVR Agreement. Consummation of the Merger is subject to the approval of the Company’s stockholders and other customary closing conditions. The Merger is expected to close in the third quarter of 2026.

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 and commercializing bempedoic acid and the bempedoic acid / ezetimibe tablet. 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. While we began to generate revenue from the sale of our products in 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 and warrants, the incurrence of indebtedness, through collaborations with third parties and revenue interest and royalty interest purchase agreements. We have incurred losses in each year since our inception.
We have never been profitable. Our net loss was $25.2 million for the three months ended March 31, 2026. Our net loss was $40.5 million for the three months ended March 31, 2025. Substantially all of our net losses resulted from costs incurred in connection with research and development programs and selling, general and administrative costs associated with our operations. We expect to incur expenses and operating losses for the immediate future in connection with our ongoing activities, including, among others:

commercializing NEXLETOL and NEXLIZET in the U.S.; and
pursuing other research and development activities.
Accordingly, we may need additional financing to support our continuing operations and further the development and commercialization 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 when needed or on acceptable terms, or at all. Our failure to raise capital as and when needed would have a
28

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 ACLY, inhibitor that lowers LDL-C and cardiovascular risk by reducing cholesterol biosynthesis and up-regulating LDL receptors. Completed Phase 3 studies whose primary endpoint was LDL-C lowering were conducted in more than 3,000 patients, with over 2,000 patients treated with NEXLETOL, and demonstrated an average 18% placebo corrected LDL-C lowering when used in patients on moderate or high-intensity statins. The completed Phase 3 Cholesterol Lowering via Bempedoic acid, an ACL-Inhibiting Regimen (CLEAR) Outcomes trial in patients unwilling or unable to take statins and who had, or were at high risk for, CVD demonstrated on average a 20% placebo corrected LDL-C reduction, and a resulting 13% lower risk of major cardiovascular events versus placebo. NEXLETOL was approved by the FDA in February 2020, with the label expanded to include an indication for cardiovascular risk reduction March 2024, and received a subsequent update to the cardiovascular risk reduction indication in November 2025 to encompass all components of the primary composite endpoint from CLEAR Outcomes.
NEXLIZET contains bempedoic acid and ezetimibe and lowers elevated LDL-C through complementary mechanisms of action by inhibiting cholesterol synthesis in the liver and cholesterol absorption in the intestine. Phase 3 data demonstrated NEXLIZET lowered LDL-C by a mean of 38% compared to placebo when added on to maximally tolerated statins. NEXLIZET was approved by the FDA in February 2020, with the label expanded to include an indication for cardiovascular risk reduction in March 2024, and received a subsequent update to the cardiovascular risk reduction indication in November 2025 to encompass all components of the primary composite endpoint from CLEAR Outcomes.

NILEMDO is a first-in-class ACLY inhibitor that lowers LDL-C and cardiovascular risk 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 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. In May 2024, the EC approved an expanded indication for NILEMDO to reduce cardiovascular risk in patients with or at high risk for ASCVD.

NUSTENDI contains bempedoic acid and ezetimibe and lowers elevated LDL-C through complementary mechanisms of action by inhibiting cholesterol synthesis in the liver and cholesterol 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. In May 2024, the EC approved an expanded indication for NUSTENDI to reduce cardiovascular risk in patients with or at high risk for ASCVD.

During the three months ended March 31, 2026, we incurred $3.0 million in expenses related to ongoing clinical studies, including our pediatric program.
During the three months ended March 31, 2025, we incurred $4.0 million in expenses related to ongoing clinical studies.
Financial Operations Overview
Product sales, net
Product sales, net is related to our sales of NEXLETOL and NEXLIZET. NEXLETOL and NEXLIZET were commercially available in the U.S. on March 30, 2020 and June 4, 2020, respectively.
Collaboration revenue
Collaboration revenue is related to our collaboration agreements with Daiichi Sankyo Europe GmbH, or DSE, Otsuka, and Daiichi Sankyo Co. Ltd, or DS, and our other ex-U.S. collaboration partners. Collaboration revenue for the three months ended March 31, 2026 and 2025 was primarily related to sales of bulk tablets, finished product and active pharmaceutical ingredient, or API, under our supply agreements and royalty revenue received from our collaboration partners. Under contracted supply
29

Table of Contents
agreements with ex-U.S. collaborators, we may manufacture and supply quantities of API, finished product or bulk tablets reasonably required by ex-U.S. collaboration partners for the development or sale of licensed products in their respective territory. We recognize revenue when the collaboration partner has obtained control of the API, finished product, or bulk tablets. We also receive royalties from the commercialization of such products, and record our share of the variable consideration, representing a percentage of net product sales, as collaboration revenue in the period in which such underlying sales occur and costs are incurred by the collaborators.
Cost of Goods Sold
Cost of goods sold is related to our net product sales of NEXLETOL and NEXLIZET and our supply agreements with our collaboration partners.
Research and Development Expenses
Our research and development expenses consist primarily of costs incurred in connection with the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and any other product candidate we may choose to pursue, 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 tablet and our early-stage pipeline assets. 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 as they relate to other development programs or additional indications we choose to pursue such as the development of our next generation ACLY inhibitors. We expect research and development expenses to remain consistent in 2026 as we continue our phase III pediatric trial and continue progressing our preclinical pipeline. We cannot determine with certainty the duration and completion costs associated with the ongoing or future clinical studies of bempedoic acid and the bempedoic acid / ezetimibe combination tablet or any other product candidate we may choose to pursue. The duration, costs and timing associated with the development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet will depend on a variety of factors, including uncertainties associated with the results of our clinical studies and our ability to obtain regulatory approval outside the U.S., Europe, Japan, and other currently approved countries. 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 tablet, we could be required to expend significant additional financial resources and time on the completion of clinical development or post-commercialization clinical studies of bempedoic acid and the bempedoic acid / ezetimibe combination tablet.

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. 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 net product sales and royalty purchase agreement. 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, 2025.

Table of Contents
Product sales, net
Product sales, net for the three months ended March 31, 2026 was $43.4 million compared to $34.9 million for the three months ended March 31, 2025, an increase of $8.5 million. The increase is primarily due to prescription growth volumes of NEXLETOL and NEXLIZET compared to the first quarter of 2025.
Collaboration revenue
Collaboration revenue recognized from our collaboration agreements for the three months ended March 31, 2026 was $36.7 million compared to $30.1 million for the three months ended March 31, 2025, an increase of $6.6 million. The increase is due to increased royalty sales growth within our partner territories.
Cost of goods sold
Cost of goods sold for the three months ended March 31, 2026 was $34.6 million compared to $31.5 million for the three months ended March 31, 2025, an increase of approximately $3.1 million. The increase is primarily related to an increase in selling costs for certain inventory, resulting in an increase in the inventory reserves, partially offset by production related write-offs in the three months ended March 31, 2025.

Research and development expenses
Research and development expenses for the three months ended March 31, 2026, were $9.0 million, compared to $12.6 million for the three months ended March 31, 2025, a decrease of $3.6 million. The decrease in research and development expenses was primarily attributable to timing on our ongoing clinical studies and preclinical studies.
Selling, general and administrative expenses
Selling, general and administrative expenses for the three months ended March 31, 2026, were $43.1 million, compared to $43.0 million for the three months ended March 31, 2025, an increase of $0.1 million. The increase in selling, general and administrative expenses was primarily attributable to increased legal costs associated with the ANDA litigation and increased media costs offset partially by a decrease in compensation costs.
Interest expense
Interest expense for the three months ended March 31, 2026, was $19.8 million, compared to $19.4 million for the three months ended March 31, 2025, an increase of $0.4 million. Interest expense for the three months ended March 31, 2026 and 2025 was related to our royalty sale liability, Loan and convertible notes and the associated amortization of debt issuance costs and original issue discounts. The increase in interest expense was primarily attributable to interest on our royalty sale liability and Loan, partially offset by lower convertible debt interest due to the payback of our 2020 Notes in November 2025.
Other income, net
Other income, net for the three months ended March 31, 2026, was $1.2 million, compared to $1.1 million for the three months ended March 31, 2025, an increase of $0.1 million. This increase was primarily due to higher interest income due to higher cash and cash equivalents.
Liquidity and Capital Resources
While we began to generate revenue from the sales of our products in 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 and warrants, the incurrence of indebtedness, milestone payments from collaboration agreements, and our revenue interest and royalty purchase agreements. Pursuant to the license and collaboration agreements with DSE, DS, and Otsuka, we are eligible for substantial additional sales and regulatory milestone payments and royalties.

On October 10, 2025, the underwriters gave notice to the Company of their partial election exercise the underwriters' option to purchase 1,065,000 additional shares, which closed on October 14, 2025. Giving effect to the partial exercise of underwriters' option, the Company issued an aggregate of 31,065,000 shares of Common Stock in the 2025 Offering, with net proceeds to the Company of approximately $72.6 million, after deducting the underwriting discount and offering expenses of approximately $5.1 million.
On February 21, 2023, we entered into a Controlled Equity Offering Sales Agreement with Cantor Fitzgerald & Co., as sales agent, to provide for the issuance and sale by us of up to $70.0 million of shares of our common stock from time to time in “at-the-market” offerings, or the 2023 ATM Program, pursuant to our existing Form S-3 and the prospectus supplement filed on February 21, 2023. During the year ended December 31, 2025, we issued 7,661,505 shares of common stock resulting in net proceeds of approximately $15.4 million after deducting approximately $0.4 million of commissions and other expenses, pursuant to the 2023 ATM Program.

On April 2, 2026, or the Closing Date, we entered into the First Amendment to Credit Agreement, or the Amendment, amending that certain Credit Agreement, dated as of December 13, 2024. The Amendment, among other things, provides for the incurrence of additional term loans in an aggregate principal amount of $25.0 million to be used, among other things, to finance a portion of the Company's acquisition of Corstasis, which included an upfront payment of $75.0 million on April 2, 2026. Amounts available under the First Amendment Term Loans were borrowed in full on the Closing Date. The First Amendment Term Loans bear the same terms as the outstanding term loans under the Existing Credit Agreement. On the Closing Date, the Company entered into a Royalty Purchase Agreement with Athyrium Opportunities IV Acquisition LP, or the Purchaser. Pursuant to the Purchase Agreement, the Purchaser purchased for $50.0 million a portion of the royalties payable to the Company on net sales of Bempedoic Acid (as defined in the License and Collaboration Agreement) and any other Licensed Products (as defined in the License and Collaboration Agreement) in the Otsuka Territory (as defined in the License and Collaboration Agreement), and of the regulatory and commercial milestones payable, in each case, pursuant to the License and Collaboration Agreement dated as of April 17, 2020, between Otsuka and the Company, as amended. The Purchaser acquired 100% of the Receivables until such time as the Purchaser receives an aggregate amount equal to $100.0 million. Following receipt of such amount, 100% of all Receivables will revert to the Company.
We anticipate that we will incur operating losses for the immediate future as we continue to incur substantial expenses related to the ongoing commercialization of NEXLETOL and NEXLIZET, the integration of Corstasis and ongoing commercialization of Enbumyst, and expenses associated with our research and development activities. We anticipate that our current cash and cash equivalents, expected future net product sales of NEXLETOL and NEXLIZET, and expected future revenue under our collaboration agreements is sufficient to fund continuing operations for the foreseeable future.

As of March 31, 2026, our primary sources of liquidity were our cash and cash equivalents which totaled $156.2 million and does not include the net cash received from the Amendment to the Credit Agreement or Royalty Purchase Agreement with the Purchaser or the net cash up-front consideration paid to Corstasis for the transactions from the Corstasis Merger Agreement, as described above. We invest our cash equivalents in highly liquid, interest-bearing investment-grade securities to preserve principal.
The following table summarizes the primary sources and uses of cash for the periods presented below:

Table of Contents
Net cash used in operating activities totaled $27.7 million and $22.6 million for the three months ended March 31, 2026 and 2025 consisted primarily of net product sales of NEXLETOL and NEXLIZET and collaboration revenue fully 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 tablet and our other early stage pipeline assets, adjusted for non-cash items such as royalty revenue paid or to be paid to OMERS, stock-based compensation expense, interest expense related to our royalty sale agreement, amortization of issuance costs on our convertible notes, depreciation and amortization and changes in working capital, including increases in prepaid inventory.
Investing Activities
Net cash used in investing activities of $0.2 million for the three months ended March 31, 2026 consisted of purchases of property, plant, and equipment. There was no cash used in or provided by investing activities for the three months ended March 31, 2025.
Financing Activities
Net cash provided by financing activities of $16.2 million for the three months ended March 31, 2026 related to cash received from the exercise of our warrants. Net cash used in financing activities of $7.5 million for the three months ended March 31, 2025 related primarily to payments of issuance costs on our December 2024 Credit Agreement and Exchange Transaction.
On October 7, 2025, we entered into the 2025 Underwriting Agreement with Piper Sandler & Co. and Cantor Fitzgerald & Co., as representatives of the underwriters, pursuant to which we issued and sold an aggregate of 31,065,000 shares of Common Stock, which includes the partial exercise of the underwriters’ option to purchase 1,065,000 additional shares, at the public offering price of $2.50 per share. As a result of the Offering, we received approximately $72.6 million in net proceeds, after deducting the underwriting discount and offering expenses of approximately $5.1 million.

On December 13, 2024, we entered into a credit agreement, or the Credit Agreement, with GLAS USA LLC, as administrative agent, and Athyrium Opportunities IV Co-Invest 1 LP, HCR Stafford Fund II, L.P., HCR Potomac Fund II, L.P. and HCRX Investments HoldCo, L.P., as the initial lenders party thereto. The Credit Agreement provides for a $150.0 million term loan, or the Loan, which was borrowed in full at closing. Proceeds from the Loan were used repay a portion of the outstanding obligations under our 2025 Notes, and to pay an original issue discount of $3.8 million and fees and expenses in connection with the Credit Agreement of $5.4 million. The Loan will bear interest at an annual rate of 9.75% if paid in cash, and 11.75% if paid-in-kind. At the Company's option, interest on the Loan could be paid-in-kind for the first four full fiscal quarters ending after the closing date. As the Company elected to have interest on the loan paid-in-kind for the quarter ended June 30, 2025 and for the quarter ended September 30, 2025, $9.1 million was added to the principal balance of the Loan. The Credit Agreement requires quarterly interest-only payments for the first four years after the closing date and, thereafter, the Loan will partially amortize in quarterly principal payments of 12.5%, with the outstanding balance to be repaid on the maturity date of December 13, 2029. Subsequent to the quarter ended March 31, 2026, on April 2, 2026, we entered into the First Amendment to Credit Agreement, or the Amendment. The Amendment, among other things, provides for the incurrence of additional term loans in an aggregate principal amount of $25.0 million. After giving effect to the Amendment, future payments under the Loan are expected to be annual interest of $18.2 million, $23.0 million in principal in the year ended December 31, 2028, and the remaining approximately $161.1 million in principal in the year ended December 31, 2029.
On June 27, 2024, we entered into a Royalty Purchase Agreement, or the Purchase Agreement, with OMERS. Pursuant to the Purchase Agreement, we sold a portion of the royalties payable on net sales of Bempedoic Acid from our collaboration partner DSE. Pursuant to the Purchase Agreement, we received $304.7 million, less issuance costs. OMERS acquired 100% of the Royalty Interests until such time as they have received an aggregate amount equal to 1.7x of the Purchase Price (equivalent to approximately $517.9 million). Following receipt of such amount, 100% of all Royalty Interests will revert to the Company. Through March 31, 2026, the royalties recognized and settled to the Purchaser was $99.6 million. The Company expects future royalties to OMERS may range from $80.7 million in the next year to a maximum total payment of approximately $337.6 million beyond one year. A significant increase or decrease in future royalties will materially impact the royalty sale liability, interest expense and the time period for repayment. Refer to Note 8 "Sale of Future Royalties" in our condensed financial statements included in this Quarterly Report on Form 10-Q for the quarter ended March 31, 2026 for further information.
On March 22, 2023, we issued and sold, in a registered direct offering, or the Registered Direct Offering, 12,205,000 shares of our common stock, pre-funded warrants to purchase up to an aggregate of 20,965,747 shares of our common stock,
in lieu of shares of our common stock, and warrants to purchase up to 33,170,747 shares of our common stock. The combined purchase price of each share of common stock and accompanying warrant was $1.675 per share. The purchase price of each pre-funded warrant and the accompanying warrant was $1.674 (equal to the combined purchase price per share of common stock and accompanying warrant, minus $0.001). In connection with the Registered Direct Offering, we amended certain existing warrants to purchase up to an aggregate of 9,024,212 shares of our common stock that were previously issued in
34

Table of Contents
December 2021 at an exercise price of $9.00 per share and had an expiration date of December 7, 2023, such that the amended warrants have a reduced exercise price of $1.55 per share and expire three and one half years following the closing of the Registered Direct Offering, for additional consideration of $0.125 per amended warrant. The amended warrants are immediately exercisable and will expire on September 22, 2026, which may provide us with additional funding, if such amended warrants are exercised by their holders. Each pre-funded warrant is exercisable for one share of our common stock at an exercise price of $0.001 per share. The pre-funded warrants were immediately exercisable and could be exercised at any time. As of March 31, 2026, no pre-funded warrants were outstanding as all were exercised during the year ended 2023. We received net proceeds of approximately $51.3 million related to the Registered Direct Offering after deducting placement agent fees and related offering expenses of $4.2 million, and we received approximately $1.1 million in connection with the amended warrants after deducting placement fees of $0.1 million. During the three months ended March 31, 2026, 11,250,000 warrants were exercised for $16.2 million in net proceeds, after issuance fees. During the three months ended March 31, 2025, no warrants were exercised.

On December 17, 2024, we entered into an Exchange Agreement where we repaid $210.1 million aggregate principal amount of our $265.0 million 2025 Notes and associated accrued interest. Payments under the 4.00% 2025 Notes after the Exchange Transaction included annual interest of $2.2 million and a principal payment of $54.9 million. In November 2025, we repaid the 2025 Notes in full and have no future payments. Refer to Note 9 "Debt" in our condensed financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

On December 17, 2024, we issued $100.0 million aggregate principal amount of 5.75% convertible senior subordinated notes due 2030 to certain financial institutions as the initial purchasers of the convertible notes, or 2030 Notes. Future payments under the 2030 Notes include annual interest of approximately $5.8 million and a principal payment of $100.0 million in 2030. Refer to Note 9 "Debt" in our condensed financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

On February 21, 2023, we entered into a Controlled Equity Offering Sales Agreement with Cantor Fitzgerald & Co., as sales agent, to provide for the issuance and sale by us of up to $70.0 million of shares of our common stock from time to time in “at-the-market” offerings, or the 2023 ATM Program, pursuant to our shelf registration statement on Form S-3 (File No. 333-286631) filed with the SEC on April 18, 2025, including the sales agreement prospectus contained therein, as declared effective by the SEC on April 29, 2025. No shares were issued from the 2023 ATM in the three months ended March 31, 2026 and 2025. We may continue to use the 2023 ATM Program to address potential short-term or long-term funding requirements that may arise. Such program will continue to be subject to the volatility of the price of our common stock and general market conditions.

Plan of Operations and Funding Requirements
We expect to continue to incur expenses and operating losses for the immediate future in connection with our continued commercialization activities associated with NEXLETOL and NEXLIZET in the U.S., as well as the integration of Corstasis, the ongoing commercialization of Enbumyst, and efforts to realize anticipated growth opportunities and synergies. Pursuant to the license and collaboration agreements with DSE, Otsuka, and DS, we are eligible for substantial additional sales and regulatory milestone payments and royalties. We estimate that current cash resources, proceeds to be received in the future for product sales and proceeds under the collaboration agreements with DSE, DS and Otsuka are sufficient to fund operations for the foreseeable future. We have based these estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and ongoing commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and the extent to which we entered and may enter into collaborations with pharmaceutical partners regarding the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet, we are unable to estimate the amounts of increased capital outlays and operating expenses associated with completing the development and commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet. Our future funding requirements will depend on the outcome of the proposed Merger with Parent, as well as a number of other factors, including, but not limited to:

our ability to successfully develop and commercialize NEXLETOL, NEXLIZET and ENBUMYST or other product candidates;
the service and payment of potential debt maturities;
our ability to maintain existing collaborations and partnerships and our ability to establish any future collaboration or commercialization arrangements on favorable terms, if at all;

our expectations regarding the acquisition of Corstasis and the prospects associated with Enbumyst, including the potential size of the congestive heart failure market opportunity, as well as our ability to realize the anticipated benefits of the acquisition, which may not be achieved or may take longer than expected;
35

Table of Contents

our ability to continue to integrate Corstasis within our business, continue to commercialize Enbumyst, and to realize anticipated growth opportunities and synergies;

our ability to realize the intended benefits of our existing and future collaborations and partnerships, including receiving potential milestone payments from collaboration partners;

the timing and results of clinical trials and regulatory actions relating to our product candidates or those of our competitors;

our ability to expand and advance our pipeline through business development activities, including collaborations, licensing arrangements or other strategic transactions, and our ability to execute and realize the anticipated and potential benefits of any such transactions we may pursue;

developments or disputes concerning patent applications, issued patents or other proprietary rights, including challenges to the validity, scope or enforceability of our issued patents, litigation or other proceedings arising from ANDA filings or similar regulatory submissions, and our ability to defend and enforce our intellectual property rights;

delays or disruptions in review, approval, inspection, or other actions by the FDA or other applicable U.S. or foreign government regulatory authorities that could impact the timing, initiation, conduct, or completion of our clinical trials or marketing applications;

the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
the implementation of operational and financial information technology; and
the impact of macroeconomic and geopolitical developments, including inflationary pressures, interest rate fluctuations, military conflicts, such as the ongoing conflicts between Russia and Ukraine, the U.S. and Iran, and in the Middle East, capital market disruptions, disruptions of U.S. governmental agencies, whether from a future U.S. federal government shutdown or reduced resources, tariffs, trade protection measures, economic sanctions and related economic slowdowns or recessions, any of which could adversely affect our access to capital markets.

Until such time, if ever, as we can generate substantial U.S. product revenues and collaboration royalties, we expect to finance our cash needs through a combination of collaborations with third parties, strategic alliances, licensing arrangements, debt financings, 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 the rights of our common stockholders. Debt and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with pharmaceutical partners or royalty-based financing arrangements, such as the collaboration arrangement with DSE, Otsuka and DS, or our other ex-U.S. partners, or other similar arrangements with third parties, 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. Similarly, adverse macroeconomic conditions and market volatility resulting from global and national economic developments, political unrest, military conflicts, such as the ongoing conflicts between Russia and Ukraine, the U.S. and Iran, and in the Middle East, inflationary pressures, disruptions in capital markets, changes in international trade relationships, changes in or the disruptions of U.S. governmental agencies, whether from a future U.S. federal government shutdown or reduced resources, new laws and regulations or amendments to existing laws and regulations in the U.S. and foreign countries, trade protection measures, economic sanctions and economic slowdowns or recessions, including as a result of heightened geopolitical tensions or increasing concerns regarding a potential global recession, or other factors could materially and adversely affect our ability to consummate an equity or debt financing on favorable terms or at all. If we are unable to raise additional funds through equity or permitted debt financings or through collaborations, strategic alliances or licensing arrangements or royalty-based financing arrangements when needed and on favorable terms, if at all, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market bempedoic acid and the bempedoic acid / ezetimibe combination tablet that we would otherwise prefer to develop and market ourselves.

We do not currently have, nor did we have during the periods presented, any off-balance sheet arrangements as defined by the SEC 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, 2025.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time period specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is 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, as appropriate to allow timely decisions regarding required disclosure.

The Company carried out the evaluation required by the Exchange Act Rules 13a-15(b) and 15d-15(b), under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in the Exchange Act Rules 13a-15(e) and 15d-15(e)). Our management recognizes that any disclosure 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. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of March 31, 2026, our disclosure controls and procedures were not effective due to a material weakness in our internal control over financial reporting described below.

Previously Identified Material Weakness in Internal Control over Financial Reporting
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. As previously reported, in connection with the preparation of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, our management discovered that certain information related to our inventory and cost of sales balances was inaccurately reported in our earnings release for the quarter ended June 30, 2025, originally issued and furnished with our Current Report on Form 8-K filed on August 5, 2025. Following discovery of such errors, we filed a Current Report on Form 8-K/A that furnished a corrected version of the earnings release on August 11, 2025. As a result of the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that a material weakness in our internal control over financial reporting existed related to the accounting for inventory held at a certain third-party contract manufacturing organization, and have further concluded that such material weakness had not been remediated as of March 31, 2026.

In response to the material weakness identified above, our management performed additional analyses as deemed necessary to ensure that our financial statements were prepared in accordance with generally accepted accounting principles in the United States of America, or U.S. GAAP. Notwithstanding the material weakness in our internal control over financial reporting, our management has concluded that the condensed financial statements and related notes thereto included in this Quarterly Report on Form 10-Q present fairly, in all material respects, our financial position, results of operations and cash flows for the periods presented in conformity with U.S. GAAP.

Remediation Plan
Following identification of the material weakness disclosed above, and with oversight from the Audit Committee of our Board of Directors (the “Audit Committee”) and input from our management, we designed and implemented changes to our processes and controls to remediate the material weakness and to enhance our internal control over financial reporting, including enhanced controls related to inventory existence held at, and movements of inventory between, our third party contract manufacturing organizations. While we believe the steps taken to date and those planned for future implementation will improve the effectiveness of our internal control over financial reporting, we have not completed all remediation efforts. The material weakness cannot be considered remediated until applicable controls have operated for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. Accordingly, we will continue to monitor and evaluate the effectiveness of our internal control over financial reporting.

Changes in Internal Control over Financial Reporting
Other than disclosed above, there were no changes to our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings
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 Quarterly Report on 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 Quarterly Report on Form 10-Q 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 Quarterly Report on Form 10-Q. 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 Quarterly Report on Form 10-Q and in any documents incorporated in this Quarterly Report on Form 10-Q 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, 2025 and in all of the other information included or incorporated in this Quarterly Report on Form 10-Q. 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, 2025. 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.

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

On December 13, 2024, we entered into the Credit Agreement with GLAS USA LLC, as administrative agent, and Athyrium Opportunities IV Co-Invest 1 LP, HCR Stafford Fund II, L.P., HCR Potomac Fund II, L.P. and HCRX Investments HoldCo, L.P., as the initial lenders party thereto (the “Existing Credit Agreement”). On April 2, 2026 (the "Closing Date"), we entered into the First Amendment to Credit Agreement (the “Amendment”), amending the Credit Agreement. The loans provided under the Amendment bear the same terms as the outstanding term loans under the Existing Credit Agreement.

On the Closing Date, the Company entered into a Royalty Purchase Agreement with Athyrium Opportunities IV Acquisition LP (the “Purchaser”). Pursuant to the Purchase Agreement, the Purchaser purchased for $50 million a portion of the royalties payable to the Company on net sales of Bempedoic Acid (as defined in the License and Collaboration Agreement) and any other Licensed Products (as defined in the License and Collaboration Agreement) in the Otsuka Territory (as defined in the License and Collaboration Agreement), and of the regulatory and commercial milestones payable, in each case, pursuant to the License and Collaboration Agreement dated as of April 17, 2020, between Otsuka Pharmaceutical Co., Ltd. and the Company, as amended. The Purchaser acquired 100% of the Receivables until such time as the Purchaser receives an aggregate amount equal to $100 million. Following receipt of such amount, 100% of all Receivables will revert to the Company.

The Existing Credit Agreement provided for a $150.0 million term loan, or the Existing Loan, which was borrowed in full at the original closing on December 13, 2024. Proceeds from the Existing Loan were used to repay a portion of the outstanding obligations under the Company's existing $265.0 million aggregate principal amount 4.00% Convertible Senior Subordinated Notes due November 2025, or the 2025 Notes, and to pay fees and expenses in connection with the Credit Agreement. The Amendment, among other things, provides for the incurrence of additional term loans in an aggregate principal amount of $25 million which was used, among other things, to finance a portion of the acquisition of Corstasis. Amounts available under the Amendment were borrowed in full on the Closing Date. The Existing Loan, together with the loans under the Amendment, are collectively referred to herein as the “Loans”. See Note 9 "Debt" and Note 16 "Subsequent Events" in the notes to our financial statements included elsewhere in this Quarterly Report on Form 10-Q for a further discussion on the Credit Agreement and convertible notes.

39

Table of Contents
The Credit Agreement, as amended, could have important negative consequences to the holders of our securities. For example, a portion of our cash flow from operations will be needed to pay certain interest to the Lenders and will not be available to fund future operations.

Interest payments under the Credit Agreement, as amended, will increase our cash outflows. The Loans bear interest at an annual rate of 9.75% if paid in cash, and 11.75% if paid-in-kind. At our option, interest on the Loans may be paid-in-kind for the first four full fiscal quarters ending after the respective closing date. As we elected to have interest on the Existing Loan paid-in-kind for the quarter ended June 30, 2025 and for the quarter ended September 30, 2025, $9.1 million was added to the principal balance of the Existing Loan. The Credit Agreement, as amended, requires quarterly interest-only payments for the first four years after the Closing Date and, thereafter, the Loans will partially amortize in quarterly principal payments of 12.5%, with the outstanding balance to be repaid on the maturity date. Our future operating performance is subject to market conditions and business factors that are beyond our control. If our cash inflows 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. There is no assurance that if we are required to secure funding we can do so on terms acceptable to us, or at all. Failure to pay certain amounts when due would result in a default under the Credit Agreement, as amended, and result in foreclosure on certain of our assets which would have a material adverse effect.

The Credit Agreement, as amended, contains a financial covenant to maintain minimum liquidity of $50.0 million. The Credit Agreement, as amended, contains affirmative and negative covenants customary for a senior secured loan. The negative covenants under the Credit Agreement, as amended, limit our ability and our subsidiaries to, among other things, dispose of assets, engage in mergers, acquisitions, and similar transactions, incur additional indebtedness, grant liens, make investments, pay dividends or make distributions or certain other restricted payments in respect of equity, prepay other indebtedness, enter into restrictive agreements, undertake fundamental changes or amend certain material contracts, in each case subject to certain exceptions.

The Credit Agreement, as amended, also contains certain customary events of default, including, but not limited to, a failure to comply with the covenants therein. If an event of default has occurred and continues beyond any applicable cure period, the administrative agent or the required lenders may accelerate all outstanding obligations under the Credit Agreement, as amended, and/or exercise any other remedies provided under the loan documents. Any declaration by the Lenders of an event of default under the Credit Agreement, as amended, could significantly harm our financial condition, business and prospects and could cause the price of our common stock to decline.

We may not realize the anticipated benefits of the acquisition of Corstasis, or those benefits may take longer to realize than expected.

On April 2, 2026, we completed the acquisition of Corstasis. The success of the acquisition will depend, in part, on our ability to effectively integrate Corstasis into our business, continue to commercialize Enbumyst, and realize anticipated growth opportunities and synergies. The integration process may be complex, costly and time-consuming, and could result in disruptions to our existing operations, diversion of management attention and potential difficulties in retaining key personnel, partners and other business relationships. There can be no assurance that we will realize the anticipated benefits of the acquisition within the expected time frame or at all.

As a result of the acquisition, we have assumed Corstasis’ liabilities and obligations, including legal, financial, regulatory and compliance matters, as well as post-approval regulatory requirements with respect to Enbumyst and obligations under supply, manufacturing and other material agreements. These obligations may require significant ongoing cost and investment, and if we have underestimated such costs or are unable to satisfy these obligations, our business, financial condition and results of operations could be adversely affected. In addition, we may be required to devote substantial resources to integration-related activities, which could cause us to forego or delay the pursuit of other opportunities.

Further, the acquisition may expose us to unknown, contingent or other liabilities that we did not identify or fully assess prior to closing. Any such liabilities or problems could have an adverse effect on our business, financial condition and results of operations.

Risks Related to the Merger and the Merger Agreement

We may not complete the Merger with Parent within the timeframe we anticipate or at all, which could have an adverse effect on our business, financial results and/or operations.

On May 1, 2026, we entered into the Merger Agreement with Parent, and MergerCo, pursuant to which, subject to the terms and conditions thereof, MergerCo will merge with and into the Company with the Company continuing as the surviving corporation and a wholly owned subsidiary of Parent (the “Merger”). Subject to the terms and conditions set forth in the Merger

Agreement, at the Effective Time, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock (i) owned by Parent or MergerCo, (ii) owned by the Company as treasury shares or (iii) held by any person who properly exercises appraisal rights under Delaware law), will be converted into the right to receive (A) the Per Share Cash Consideration, plus (B) one contractual contingent value right per share, representing the right to participate in contingent payments in cash, without interest, upon the achievement of certain milestones as set forth in the CVR Agreement. Each CVR will entitle the holder to its pro rata share, in cash, of contingent payments of up to an additional $100.0 million in the aggregate, without interest and less any applicable tax withholding, upon the achievement of specified milestones during the applicable milestone periods as set forth in the CVR Agreement. Consummation of the Merger is subject to the approval of the Company’s stockholders and other customary closing conditions. The Merger is expected to close in the third quarter of 2026.

If the Merger is not completed within the expected timeframe or at all, we may be subject to a number of material risks in addition to the risks of continuing to operate our business. The price of our common stock may decline to the extent that current market prices of our common stock reflect a market assumption that the Merger will be completed on a timely basis. We could be required to pay Parent a termination fee in the amount of $34,154,539 if the Merger Agreement is terminated under specified circumstances, including termination by the Company in order to enter into an acquisition agreement providing for a Superior Proposal (as defined in the Merger Agreement). The failure to complete the transaction also may result in negative publicity and negatively affect our relationship with our stockholders, employees, strategic partners and suppliers. We may also be required to devote significant time and resources to litigation related to any failure to complete the Merger or related to any enforcement proceeding commenced against us to perform our obligations under the Merger Agreement.

Our ability to complete the Merger is subject to certain closing conditions and the receipt of consents and approvals from our stockholders and government entities that may impose conditions that could adversely affect us or cause the Merger to be abandoned.

Completion of the Merger is subject to certain closing conditions, including, among other things, the adoption of the Merger Agreement by the Company’s stockholders and the expiration or early termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and the absence of governmental injunctions or other legal restraints prohibiting the Merger. If we are unable to obtain the requisite stockholder approval or the government imposes any injunctions or restraints on the Merger, we will not be able to close the Merger. Further, the granting of regulatory approvals pursuant to the HSR Act could involve the imposition of additional conditions on the closing of the Merger. The imposition of such conditions or the failure or delay to obtain regulatory approvals could have the effect of delaying completion of the Merger or of imposing additional costs or limitations on us or may result in the failure to close the Merger.

In addition, the obligation of Parent to consummate the Merger is conditioned upon, among other things, the accuracy of our representations and warranties (subject to certain materiality exceptions), and our compliance in all material respects with our obligations under the Merger Agreement. We cannot provide any assurance that the conditions to the consummation of the Merger will be satisfied or waived, or will not result in the abandonment or delay of the Merger.

While the Merger Agreement is in effect, we are subject to certain restrictions on our business activities.

While the Merger Agreement with Parent is in effect, we are subject to customary restrictions on our business activities, generally requiring us to conduct our business in the ordinary course, consistent with past practice, and subjecting us to a variety of specified limitations absent Parent’s prior consent. These limitations include, among other things, restrictions on our ability to hire employees, sell, transfer, lease, license, dispose or assign tangible assets exceeding certain dollar thresholds or Company intellectual property (subject to certain exceptions), make investments, enter into, modify or terminate material contracts or employee plans (subject to certain exceptions), repurchase or issue securities, pay dividends, make capital expenditures exceeding certain dollar thresholds, commence or settle any legal proceeding (subject to certain exceptions), amend our organizational documents or incur indebtedness. These restrictions could prevent us from pursuing strategic business opportunities, taking actions with respect to our business that we may consider advantageous and responding effectively and/or timely to competitive pressures and industry developments, and may as a result materially and adversely affect our business, results of operations and financial condition.

The Merger Agreement limits our ability to pursue alternatives to the Merger.

The Merger Agreement contains provisions that make it more difficult for us to enter into alternative transactions. As is typical for transactions like the Merger, the Merger Agreement contains certain provisions that restrict our ability to, among other things, initiate, solicit, cause or knowingly encourage (including by way of furnishing non-public information) or otherwise knowingly assist or knowingly facilitate the submission of inquiries regarding, or the making of any proposal or offer that constitutes a Takeover Proposal or Potential Takeover Proposal (as defined in the Merger Agreement). The Merger Agreement also provides that our Board may only change their recommendation that the Company's stockholders approve the

Table of Contents
Merger in certain limited circumstances. These provisions could discourage third parties from making alternative proposals and, as a result, may limit our ability to pursue potentially more favorable transactions.

In certain instances, the Merger Agreement requires us to pay a termination fee to Parent, which could require us to use available cash that would have otherwise been available for general corporate purposes.

Under the terms of the Merger Agreement, we may be required to pay Parent a termination fee in the amount of $34,154,539 if the Merger Agreement is terminated under specific circumstances described in the Merger Agreement, including, but not limited to, in connection with a change in the recommendation of our Board or a termination of the Merger Agreement by us to enter into an acquisition agreement providing for a Superior Proposal (as defined in the Merger Agreement). If the Merger Agreement is terminated under such circumstances, the termination fee we may be required to pay under the Merger Agreement may require us to use available cash that would have otherwise been available for general corporate purposes and other uses. For these and other reasons, termination of the Merger Agreement could materially and adversely affect our business operations and financial condition, which in turn would materially and adversely affect the price of Company Common Stock.
We have incurred direct and indirect costs as a result of the Merger and we may incur additional direct and indirect costs whether or not the Merger is consummated.

We have incurred significant non-recurring costs in connection with the Merger Agreement. These costs include legal, financial advisory, accounting, consulting and other professional fees, as well as regulatory filing fees and other transaction-related expenses. We have incurred these costs and expect that we will continue to incur additional costs whether or not the Merger is consummated. In addition, if we terminate the Merger Agreement or the termination date passes and the Merger has not been effected, we will have incurred substantial costs from the Merger that we will not be able to recover, and we may incur further costs before the Merger is consummated, and such expenses could have an adverse impact on our business, financial results and operations.

Stockholder litigation could prevent or delay the completion of the Merger or otherwise negatively impact our business, financial condition and results of operations.

Stockholders of the Company may file lawsuits against the Company and/or the directors and officers of the Company in connection with the Merger. One of the conditions to the closing is that no judgment enacted, promulgated, issued, entered, amended or enforced by any Governmental Authority (as defined in the Merger Agreement) of competent jurisdiction or any applicable law shall be in effect enjoining, restraining or otherwise making illegal, preventing or prohibiting the consummation of the Merger. If any plaintiff was successful in obtaining an injunction prohibiting us from completing the Merger, then such injunction may delay or prevent the effectiveness of the Merger and could result in significant costs to us, including any cost associated with the indemnification of directors and officers. We may incur costs relating to the defense or settlement of any stockholder lawsuits filed in connection with the Merger. Stockholder lawsuits may divert management attention from management of our business or operations. Such litigation could have an adverse effect on our business, financial condition and results of operations and could prevent or delay the completion of the Merger.

Our stockholders may not receive any payment on the CVR and the CVR may expire valueless.

The holders of the CVRs will include (i) holders of shares of Company Common Stock that are canceled and converted into the right to receive the Merger Consideration pursuant to the Merger Agreement, (ii) holders of Company RSUs and Company Stock Options that are canceled and converted into the right to receive the consideration specified above upon consummation of the Merger, (iii) holders of outstanding warrants of the Company that elect to receive the Merger Consideration upon exercise following the Closing pursuant to the terms of the applicable warrant, and (iv) holders of the Company’s outstanding convertible notes that convert such convertible notes following the Closing pursuant to the terms of the related indenture (each as defined in the Merger Agreement). Each CVR will represent the right of such holders of the CVRs to participate in up to two cash payments, without interest and less any applicable tax withholding, contingent upon the achievement of certain milestones during the applicable milestone periods as described below:

Holders of CVRs will be entitled to participate in an aggregate contingent cash payment of up to $40 million if annual Net Sales (as defined in the CVR Agreement) of certain products containing bempedoic acid (including NEXLETOL® and NEXLIZET®) in the United States during the period from January 1, 2027 through December 31, 2027 exceed $300 million. The aggregate milestone payment amount will be: (i) $40.0 million if annual Net Sales of such products are equal to or greater than $350.0 million; (ii) an amount between $0 and $40.0 million, determined by linear interpolation, if annual Net Sales of such products exceed $300.0 million but are less than $350.0 million; and (iii) $0 if annual Net Sales of such products are equal to or less than $300.0 million. Any such aggregate milestone payment amount, to the extent achieved, will be divided among the CVRs outstanding at the close of business on the date of the
42

Table of Contents
milestone achievement notice to determine the applicable milestone payment per CVR, in each case subject to the terms and conditions set forth in the CVR Agreement.

Holders of CVRs also will be entitled to participate in an aggregate contingent cash payment of $60 million if annual Net Sales (as defined in the CVR Agreement) of certain products containing bumetanide (including ENBUMYST®) in the United States equal or exceed $160.0 million in any single calendar year during the period commencing on (and including) the Effective Time and ending on December 31, 2030. Any such aggregate milestone payment amount, if achieved, will be divided among the CVRs outstanding at the close of business on the date of the milestone achievement notice to determine the applicable milestone payment per CVR, in each case subject to the terms and conditions set forth in the CVR Agreement.

Parent and the Company will be required to use Diligent Efforts (as defined in the CVR Agreement) to achieve each milestone, and the applicable milestone payment for each of the two milestones shall only be paid once per milestone, if at all, subject to achievement of the applicable milestone in accordance with the CVR Agreement. Milestone payments to holders of CVRs issued in respect of certain out-of-the-money options will be subject to additional reduction mechanics in accordance with the CVR Agreement.

There can be no assurance any payments will be made with respect to the CVRs. The CVRs will not be transferable, except in the limited circumstances specified in the CVR Agreement, will not have any voting or dividend rights, and will not represent any equity or ownership interest in us or any constituent party to the Merger Agreement. Accordingly, the right of any of our stockholders to receive any future payment on or derive any value from the CVRs will be contingent solely upon the occurrence of certain events, as outlined in the CVR Agreement, and if no such events are achieved for any reason within the time periods specified in the CVR Agreement, no payments will be made under the CVRs, and the CVRs will expire valueless.

Item 5. Other Information

During the quarter ended March 31, 2026, none of our directors or officers (as defined in Rule 16a-1 under the Exchange Act) adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement" (as those terms are defined in Item 408 of Regulation S-K).

Esperion generated $80.1 million in Q1 2026 revenue, up from $65.0 million a year earlier. Net loss narrowed to $25.2 million, compared with $40.5 million, reflecting higher product sales and collaboration revenue alongside continued operating and interest expenses.

What are the key terms of the proposed acquisition of Esperion (ESPR) by Essence Parent Inc.?

Under the merger agreement, each Esperion share will convert into $3.16 in cash plus one contingent value right. Each CVR allows holders to share in up to $100 million of milestone-based cash payments. Closing requires stockholder approval and other customary conditions.

What is Esperion’s (ESPR) liquidity position and debt load as of March 31, 2026?

Esperion held $156.2 million in cash and cash equivalents at March 31, 2026. This is offset by a $291.2 million royalty sale liability and long-term borrowings including a $150 million term loan and $100 million of 2030 convertible notes, plus other obligations.

What is the Corstasis acquisition and how does it affect Esperion (ESPR)?

Esperion completed the Corstasis merger, paying $75 million upfront in cash with up to $180 million in potential milestones. The deal adds Enbumyst, an FDA-approved bumetanide nasal spray for edema in heart, hepatic, and renal disease, expanding Esperion’s cardiovascular-focused product portfolio.

How important are collaboration revenues for Esperion Therapeutics (ESPR)?

Collaboration revenue reached $36.7 million in Q1 2026, up from $30.1 million a year earlier. These receipts mainly reflect royalties and supply sales to partners like Daiichi Sankyo Europe, Otsuka, and Daiichi Sankyo Co. Ltd., and form a substantial portion of Esperion’s total revenue mix.

What is Esperion’s (ESPR) exposure to royalty sale arrangements as of Q1 2026?

Esperion carries a $291.2 million royalty sale liability related to DSE bempedoic acid royalties sold for upfront cash. In April 2026, it also sold Otsuka-related receivables for $50 million, with the buyer receiving payments until total receipts reach $100 million, after which royalties revert.

What are the ANDA litigation developments affecting Esperion (ESPR) products?

Esperion faces multiple ANDA challenges to NEXLETOL and NEXLIZET patents, but has settled with several filers who agreed not to launch generics before April 19, 2040 absent specified events. Litigation against remaining filers continues in New Jersey federal court, with trial expected no earlier than January 2027.
