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, 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 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, 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. In addition, Otsuka Pharmaceutical Co., Ltd., or Otsuka, our Japanese collaborator, announced that the primary endpoint of LDL-C reduction from baseline at Week 12 was achieved with statistical significance in the Phase 3 clinical trial in Japan for bempedoic acid as a treatment for hypercholesterolemia. Otsuka filed a New Drug Application, or NDA, in Japan in November 2024, with expected approval and National Health Insurance, or NHI, pricing in the second half of 2025. We filed supplemental NDAs for product approvals in Canada in November 2024 and our collaboration partners plan to file in Australia and Israel in the first half of 2025.

We completed a global cardiovascular outcomes trial, or CVOT, —known as Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes. The trial was designed to evaluate whether treatment with bempedoic acid reduced the risk of cardiovascular events in adult patients who are statin averse and who have CVD or are at high risk for CVD. We initiated the CLEAR Outcomes CVOT in December 2016 and fully enrolled the study with nearly 14,000 patients in August 2019. The primary endpoint of the study was the effect of bempedoic acid on four types of major adverse cardiovascular events, or MACE, (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization; also referred to as "four-component MACE"). CLEAR Outcomes was an event-driven trial and concluded once the predetermined number of MACE endpoints occurred. The study showed that bempedoic acid demonstrated significant cardiovascular risk reductions and significantly reduced the risk of heart attack and coronary revascularization as compared to placebo. These results were seen in a broad population of primary and secondary prevention patients who are unable to maximize or tolerate a statin. The proportions of patients experiencing adverse events and serious adverse events were similar between the active and placebo treatment groups. Bempedoic acid, contained in NEXLETOL (bempedoic acid) tablets and NEXLIZET (bempedoic acid and ezetimibe) tablets, became the first LDL-C lowering therapy since statins to demonstrate the ability to lower hard ischemic events, not only in those with atherosclerotic cardiovascular disease, or ASCVD, but also in the large number of primary prevention patients for whom limited therapies exist.

On March 22, 2024, we 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, and are now the only LDL-C lowering non-statin drugs indicated for primary prevention patients.

On May 22, 2024, we announced that the EC approved the label update of both NILEMDO and NUSTENDI as treatments for hypercholesterolemia and to reduce the risk of adverse cardiovascular events. The EC’s decisions to update the labels of

Table of Contents

bempedoic acid and the bempedoic acid / ezetimibe fixed dose combination are based on the positive CLEAR Outcomes trial results and makes them the first and only LDL-C lowering treatments indicated for primary and secondary prevention of cardiovascular events. NILEMDO and NUSTENDI are approved to reduce cardiovascular risk in patients with or at high risk for ASCVD.

On June 27, 2024, we entered into a Royalty Purchase Agreement, or the Purchase Agreement, with OCM IP Healthcare Portfolio LP, or OMERS, a limited partnership formed under the laws of the Province of Ontario, Canada, or the Purchaser. Pursuant to the Purchase Agreement, we sold to the Purchaser, and the Purchaser purchased for approximately $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, or DSE, and the Company, as amended, or the License and Collaboration Agreement and such royalties being the Royalty Interests).

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 approximately $517.9 million). Following receipt of such amount, 100% of all Royalty Interests will revert to us. The Purchase Agreement contains other customary terms and conditions, including representations and warranties, covenants and indemnification obligations in favor of each party.

On June 27, 2024, we repurchased Revenue Interests outstanding under the Revenue Interest Purchase Agreement, or the RIPA, dated effective as of June 26, 2019, as amended, by and among the Company, the purchasers party thereto, or the Purchasers, and Eiger III SA LLC, or Oberland, as the collateral agent and administrative agent, or the Purchaser Agent, and satisfied all other Obligations (as defined in the RIPA) owed to the Purchasers and the Purchaser Agent by paying to the Purchaser Agent, for the benefit of the Purchasers, a payment in cash of approximately $343.8 million, or the Repurchase Consideration.Following the payment of the Repurchase Consideration, (a) all Revenue Interests were deemed to have been repurchased and all Obligations, debts and liabilities of the Company under the RIPA and the Transaction Documents (as defined in the RIPA) were deemed to have been paid and satisfied in full, and automatically released, discharged and terminated, and the RIPA and all other Transaction Documents automatically terminated, and all liens, security interests and pledges in favor of, granted to or held by the Purchaser Agent to secure the Obligations under the Transaction Documents were automatically terminated and released.

On December 13, 2024, we entered into a credit agreement, or 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. 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 existing $265 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.

On December 17, 2024, we entered into privately negotiated exchange and subscription agreements, or the Agreements, with certain holders of our outstanding 2025 Notes. Pursuant to the Agreements, we issued $100.0 million aggregate principal amount of 5.75% Convertible Senior Subordinated Notes due 2030, or the 2030 Notes, consisting of (a) approximately $57.5 million principal amount of 2030 Notes, along with approximately $153.4 million in cash, including accrued interest, issued in exchange for approximately $210.1 million principal amount of the 2025 Notes, or the Exchange Transaction, and (b) approximately $42.5 million principal amount of 2030 Notes for cash.

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 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, through collaborations with third parties, revenue interest and royalty purchase agreements. We have incurred losses in each year since our inception.

We have never been profitable and our net losses were $51.7 million, $209.2 million and 233.7 million for the years ended December 31, 2024, 2023, and 2022 respectively. Our net loss for the year ended December 31, 2024 was primarily due to the loss on extinguishment on the Oberland RIPA and convertible notes Exchange Transaction, interest expense and costs incurred in connection with research and development programs and selling, general and administrative costs associated with our operations, offset partially by the Settlement Agreement with DSE and other revenue from our net product sales and collaboration agreements. Substantially all of our net losses for the years ended December 31, 2023 and 2022 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 significant expenses and operating losses for the near term 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 on acceptable terms, or at all. Our failure to raise capital as and when needed would have a material adverse effect on our financial condition and our ability to pursue our business strategy or continue operations. We will need to generate significant revenues to achieve profitability, and we may never do so.

Product Overview

NEXLETOL is a first-in-class ATP Citrate Lyase, or ACLY, inhibitor that lowers LDL-C and cardiovascular risk by reducing cholesterol biosynthesis and up-regulating the 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 20.0% placebo corrected LDL-C lowering, and a resulting 13% lower risk of major cardiovascular events versus placebo. NEXLETOL was approved by the FDA in February 2020 and received an expanded cardiovascular risk reduction indication from the FDA in March 2024.

NEXLIZET contains bempedoic acid and ezetimibe and lowers elevated LDL-C through complementary mechanisms of action by inhibiting cholesterol synthesis in the liver and absorption in the intestine. Phase 3 data demonstrated NEXLIZET lowered LDL-C by a mean of 38% compared to placebo when added on to maximally tolerated statins. NEXLIZET was approved by the FDA in February 2020 and received an expanded cardiovascular risk reduction indication from the FDA in March 2024.

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 adult patients unable to reach LDL-C goals with the maximum tolerated dose of a statin, or alone or in combination with other lipid-lowering therapies as an adjunct to diet in adult patients who are statin-intolerant, or for whom a statin is contraindicated. 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 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 years ended December 31, 2024, we incurred $6.6 million related to ongoing clinical studies. During the years ended December 31, 2023 and December 31, 2022, we incurred $46.2 million and $83.5 million, respectively, in direct expenses related to our CLEAR Outcomes CVOT and other 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 and Otsuka. Collaboration revenue in the year ended December 31, 2024 was primarily related to the settlement agreement, or Settlement Agreement, with Daiichi Sankyo Europe GmbH, or DSE, a milestone from Otsuka upon first Japanese New Drug Application, or JNDA, submission in the Otsuka Territory, sales of bulk tablets under supply agreements and royalty revenue received from collaboration partners. Collaboration revenue in the years ended December 31, 2023 and 2022 was primarily related to sales of bulk tablets under supply agreements and royalty revenue received from collaboration partners. Under contracted supply agreements with ex-U.S. collaborators, we may manufacture and supply quantities of active pharmaceutical ingredient, or API, 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 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. Refer to Note 1 and 3 in our audited financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

Cost of Goods Sold

Cost of goods sold is related to our net product sales of NEXLETOL and NEXLIZET and our supply agreements with 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 increase in 2025 as we begin our phase III pediatric trial and continue progressing our preclinical

Table of Contents

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. and Europe. For example, if a regulatory authority were to require us to conduct clinical studies beyond those that we currently anticipate will be required for the completion of clinical development or post-commercialization clinical studies of bempedoic acid or the bempedoic acid / ezetimibe combination 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.

Selling, General and Administrative Expenses

We expect our selling, general and administrative expenses will be consistent in 2025 as it was in 2024 after the additional global regulatory approvals for new product indications in 2024 and the associated expanded commercialization initiatives for NEXLETOL and NEXLIZET and increases in our associated headcount to expand our sales team.

Interest Expense

Interest expense for the year ended December 31, 2024 was related to our Royalty Purchase Agreement with OMERS, entered into on June 27, 2024, our RIPA with Oberland, our Loan, entered into on December, 13, 2024, and our convertible notes. Interest expense for the years ended December 31, 2023 and December 31, 2022 was related to our RIPA and our convertible notes.

Loss on extinguishment of debt and exchange transaction

Loss on extinguishment of debt and exchange transaction is related to the loss recognized from the termination of our RIPA with Oberland and the Exchange Transaction of our Convertible Notes.

Other Income

Other income, net, for the years ended December 31, 2024, December 31, 2023 and December 31, 2022 primarily relates to interest income and the accretion or amortization of premiums and discounts earned on our cash, cash equivalents and investment securities and also includes other income related to the sale of leased vehicles.

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.

Our significant accounting policies are described in more detail in Note 2 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K. We believe the following accounting policies to be most critical to understanding our results and financial operations.

Table of Contents

Product Sales, Net

We sell NEXLETOL and NEXLIZET to wholesalers in the U.S. and, in accordance with ASC 606, recognize revenue at the point in time when the customer is deemed to have obtained control of the product, which generally occurs upon receipt by the customer. Product sales are recorded at the net selling price, which includes variable considerations for rebates, chargebacks, co-pay assistance programs, distribution related fees, product returns, and other sales-related discounts and fees. Calculating these net product sales involves judgments and estimates. Our estimates give consideration for a range of possible outcomes which are probability-weighted for relevant factors such as contracts with customers, healthcare providers, payors and government agencies, statutorily-defined discounts applicable to government-funded programs, forecasted payor mix, customer buying and payment patterns, and other relevant factors. The reserves reflect our best estimates of the amount of consideration to which we are 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 our commercial operations we have provided constraint of our variable consideration due to its potential consumption trends. Actual amounts of consideration ultimately received may differ from our estimates. Each period, we review our estimates of rebates, co-pay assistance programs, distribution fees and other applicable provisions. If actual results vary from estimates, we adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. A 3% change to our year ended December 31, 2024 net product sales would have an impact of approximately $3.5 million.

Liability Related to the Sale of Future Royalties

In June 2024, we entered into a royalty sale agreement with OMERS for the future royalties from our collaboration agreement with DSE for up to 1.7x the purchase price, or $518 million. We evaluated the arrangement and determined the agreement should be treated as a debt instrument according to ASC 470, Debt. The royalty sale liability related to the agreement is presented net of deferred issuance costs on the balance sheets. We impute interest expense associated with this liability using the effective interest rate method which is presented as interest expense on the statements of operations. 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 agreement depending on a number of factors, including the level of forecasted royalty sales. This estimate is complex and highly judgmental due to the estimation uncertainty in determining the effective interest rate. We evaluate the interest rate quarterly based on our expectations of forecasted royalty sales from our license partner, historical experience, third-party forecasts and current market conditions utilizing the prospective method. The effective interest rate model includes royalty sales forecasts which are affected by expectations about future market conditions. A significant increase or decrease in royalties will materially impact the royalty sale liability, interest expense and the time period for repayment. A 3% increase in quarterly forecasted revenues would increase interest expense by approximately $0.2 million, increase the royalty sale liability by $0.2 million, and would have no change on the estimated time period for repayment. Issuance costs in connection with the royalty sale agreement are amortized to interest expense over the estimated term of the agreement.

Interest expense

Interest expense for the year ended December 31, 2024, was $59.3 million, compared to $59.0 million for the year ended December 31, 2023, an increase of $0.3 million. Interest expense for the year ended December 31, 2024 was related to our revenue interest liability, or RIPA, which we repurchased on June 27, 2024, of $21.6 million, our royalty sale liability, entered into on June 27, 2024, of $24.7 million, our convertible notes, of $12.2 million, and our Credit Agreement, entered into on December 13, 2024, of $0.8 million. Interest expense for the year ended December 31, 2023, was related to our revenue interest liability of $46.7 million and convertible notes of $12.3 million.

Loss on extinguishment of debt and exchange transaction

Loss on extinguishment of debt and exchange transaction for year ended December 31, 2024, was $54.9 million, with no such loss recognized for the year ended December 31, 2023. The loss on extinguishment of debt was due to the termination of our RIPA with Oberland of $53.2 million and Exchange Transaction of our convertible notes of $1.7 million.

Other income, net

Other income, net for the year ended December 31, 2024, was $8.0 million compared to $5.3 million for the year ended December 31, 2023, an increase of $2.7 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 Daiichi Sankyo and Otsuka, we are eligible for substantial additional sales and regulatory milestone payments and royalties.

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, 2024, we issued 378,902 shares of common stock resulting in net proceeds of approximately $0.5 million after deducting approximately $0.2 million of commissions and expense reimbursement payable to sales agent and other expenses, pursuant to the 2023 ATM Program. During 2023, we issued 3,312,908 shares of common stock resulting in net proceeds of approximately $4.4 million after deducting $0.4 million of underwriting discounts and commissions and other expenses, pursuant to the 2023 ATM Program.

On January 2, 2024, we entered into the Settlement Agreement with DSE to amicably resolve and dismiss the commercial dispute then pending in the Southern District of New York. Under the Settlement Agreement, DSE agreed to pay us 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, which we received in January 2024, and (2) a $25.0 million payment in the calendar quarter immediately following the calendar quarter in which the European Medicines Agency, or EMA renders a decision on the application that was filed with the EMA for a Type II(a) variation for our oral non-statin products marketed as NILEMDO® (bempedoic acid) tablets and NUSTENDI® (bempedoic acid and ezetimibe) tablets in Europe, which we received in June 2024. The legal action pending in the United States District Court for the Southern District of New York has now been dismissed.

On January 18, 2024, we entered into the Underwriting Agreement with Jefferies, as representative of the Underwriters, related to the January 2024 Offering of 56,700,000 shares of our common stock, at a purchase price to the public of $1.50 per share. The Underwriters were also granted a 30-day option to purchase up to an additional 8,505,000 shares of our common stock, at the public offering price. On January 19, 2024, Jefferies gave us notice of its election to exercise the option to purchase additional shares, in full. Giving effect to the exercise of Underwriters' option, the January Offering closed on January 23, 2024, with proceeds to the Company of approximately $90.7 million, after deducting the underwriting discount and estimated offering expenses of $7.1 million.

As part of our December 2024 Credit Agreement and Exchange Transaction for our 2025 and 2030 Notes, as described in more detail below, the Company added approximately $26.5 million of net cash and cash equivalents to the balance sheets after payments of original issue discount, issuance costs and accrued interest on the partial extinguishment of the 2025 Notes.

Table of Contents

We anticipate that we will incur operating losses for the near term future as we continue to incur substantial expenses related to the ongoing commercialization of NEXLETOL and NEXLIZET 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 near term future.

As of December 31, 2024, our primary sources of liquidity were our cash and cash equivalents which totaled $144.8 million. We invest our cash equivalents and investments in highly liquid, interest-bearing investment-grade securities and government securities to preserve principal.

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

Year Ended December 31,

(in thousands)

Net cash used in operating activities $ (23,654) $ (135,487)

Net cash (used in) provided by investing activities (317) 42,500

Net cash provided by financing activities 86,484 50,460

Net increase (decrease) in cash and cash equivalents $ 62,513 $ (42,527)

Operating Activities

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

Net cash used in operating activities totaled $23.7 million for the year ended December 31, 2024 and $135.5 million for the year ended December 31, 2023. Net cash used in operating activities for the year ended December 31, 2024 consisted primarily of net product sales of NEXLETOL and NEXLIZET, the Settlement Agreement with DSE and other cash received from our collaboration agreements 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, adjusted for non-cash expenses such as the loss extinguishment of debt associated with our RIPA and convertible note Exchange Transaction, royalty revenue paid or to be paid to OMERS, stock-based compensation expense, interest expense related to our RIPA with Oberland and royalty sale agreement, amortization of issuance costs on our convertible notes, depreciation and amortization and changes in working capital. Net cash used in operating activities for the year ended December 31, 2023 consisted of net product sales of NEXLETOL and NEXLIZET 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, adjusted for non-cash expenses such as stock-based compensation expense, interest expense related to our RIPA with Oberland and the amortization of issuance costs on our convertible notes, depreciation and amortization and changes in working capital.

The decrease in cash used in operating activities for the year ended December 31, 2024 compared to the year ended December 31, 2023 was primarily related to a decrease in net loss resulting from increases in net product sales and collaboration revenue, primarily related to our Settlement Agreement with DSE and lower research and development costs following the public presentation of our CLEAR Outcomes CVOT in 2023, partially offset by increases in selling, general, and administrative expenses due to increased commercial headcount and promotional expenses with the launch of the expanded labels in NEXLETOL and NEXLIZET, increases in inventory, and increases in cost of goods sold related to additional sales, adjusted for normal working capital and timing of cash outlays.

Investing Activities

Net cash used in investing activities of $0.3 million for the year ended December 31, 2024 consisted of purchases of property and equipment. Net cash provided by investing activities of $42.5 million for the year ended December 31, 2023 consisted primarily of net proceeds from the sales of highly liquid, interest bearing investment grade and government securities.

Table of Contents

Financing Activities

Net cash provided by financing activities of $86.5 million for the year ended December 31, 2024, related primarily to proceeds from our January 2024 Offering, royalty sale agreement, the Loan and issuance of convertible notes and warrant exercises, offset partially by the cash outlays resulting in the extinguishment of our RIPA and Exchange Transaction of convertible notes. Net cash provided by financing activities of $50.5 million for the year ended December 31, 2023, related primarily to proceeds from our registered direct offering, or Registered Direct Offering, exercise of warrants, and net proceeds from our 2023 ATM Program, partially offset by payments on our RIPA with Oberland.

On June 27, 2024, we entered into a Royalty Purchase Agreement (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 December 31, 2024, the royalties recognized and settled to the Purchaser was $26.1 million The Company expects future royalties to OMERS may range from $47.6 million in the next year to a maximum total payment of approximately $444.2 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 11 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

On June 27, 2024, we repurchased the Revenue Interests outstanding under the RIPA for $343.8 million and recognized a loss on extinguishment of debt in the statements of operations of $53.2 million. Following the repurchase in June 2024, we no longer owe payments under the RIPA. Refer to Note 10 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

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. Future payments under the 4.00% 2025 Notes include annual interest of $2.2 million and a principal payment of $54.9 million due in November 2025. Refer to Note 12 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K.

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 12 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K.

On December 13, 2024, we entered into a Credit Agreement for a $150.0 million 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 may be paid-in-kind for the first four full fiscal quarters ending after the closing date. 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. Future payments under the Loan are expected to be annual interest of $14.6 million ($15.4 million in 2025 with the additional portion related to the fourth quarter of 2024), $18.8 million in principal in the year ended December 31, 2028, and the remaining approximately $131.2 million in principal in the year ended December 31, 2029.

On April 15, 2022, we filed a new registration statement on Form S-3, which registered the offering, issuance and sale of up to $239 million of common stock from time to time in “at-the-market” offerings, or the 2022 ATM Program. On February 21, 2023, we terminated the Open Market Sales Agreement with Jefferies LLC and 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 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, 2024, we issued 378,902 shares of common stock resulting in net proceeds of approximately $0.5 million after deducting approximately $0.2 million of commissions and expense reimbursement payable to sales agent and other expenses, pursuant to the 2023 ATM Program. During the year ended December 31, 2023, we issued 3,312,908 shares of common stock resulting in net proceeds of approximately $4.4 million after deducting $0.4 million of underwriting discounts and commissions and other expenses, pursuant to the 2023 ATM Program. 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.

Table of Contents

On March 22, 2023, we issued and sold, in 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, 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 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. The warrants are immediately exercisable and will expire on September 22, 2026, which may provide us with additional funding, if such 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 December 31, 2024, no pre-funded warrants were outstanding. During the year ended December 31, 2024, we received net proceeds of approximately $14.8 million from the exercise of warrants. During the year ended December 31, 2023, we received net proceeds of approximately $8.4 million from the exercise of warrants and pre-funded warrants. During the year ended December 31, 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. Refer to Note 13 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

Plan of Operations and Funding Requirements

We expect to continue to incur expenses and operating losses for the near term future in connection with our continued commercialization activities associated with NEXLETOL and NEXLIZET in the U.S. 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 Daiichi Sankyo 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 many factors, including, but not limited to:

•our ability to successfully develop and commercialize NEXLETOL and NEXLIZET or other product candidates;

•the service and payment of potential debt maturities;

•our ability to establish any future collaboration or commercialization arrangements on favorable terms, if at all;

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

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

•the implementation of operational and financial information technology.

Until such time, if ever, as we can generate substantial U.S. product revenues, 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 your rights as a common stockholder. Debt 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, 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. If we raise funds by selling additional equity, such sale would result in dilution to our stockholders. If we are unable to raise additional funds through equity or permitted debt

Table of Contents

financings or through collaborations, strategic alliances or licensing arrangements or permitted royalty-based financing arrangements when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market bempedoic acid and the bempedoic acid / ezetimibe combination tablet that we would otherwise prefer to develop and market ourselves.

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

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We had cash and cash equivalents of approximately $144.8 million at December 31, 2024. The primary objectives of our investment activities are to preserve principal, provide liquidity and maximize income without significantly increasing risk. Our primary exposure to market risk relates to fluctuations in interest rates which are affected by changes in the general level of U.S. interest rates. Given the short-term nature of our cash equivalents, we believe that a sudden change in market interest rates would not be expected to have a material impact on our financial condition and/or results of operations. We do not have any foreign currency or other derivative financial instruments.

We maintain significant amounts of cash and cash equivalents at one or more financial institutions that are in excess of federally insured limits. We do not believe that our cash and cash equivalents have significant risk of default or illiquidity.

We contract with CROs and investigational sites globally. We are therefore subject to fluctuations in foreign currency rates in connection with these agreements. We do not hedge our foreign currency exchange rate risk.

Inflation generally affects us by increasing our cost of labor and clinical study costs. We do not believe that inflation has had a material effect on our results of operations during the year ended December 31, 2024.

Our outstanding warrants currently have an exercise price of $1.55 per share and holders of such warrants may not exercise if the market price of our common stock is below $1.55. As a result, we may be unable to obtain potential proceeds from the exercise of these warrants if the market price of our common stock does not exceed $1.55 per share.

Our 2025 Notes, which were issued in November 2020, carry a fixed interest rate of 4.0% per year. Our 2030 Notes, which were issued in December 2024, carry a fixed rate of 5.75%. Our Loan, which was issued in December 2025, carries a fixed interest rate of 9.75%. Since both convertible notes and the Loan bear interest at a fixed rate, we have no direct financial statement risk associated with changes in interest rates. We do not believe a change in interest rate has had a material effect on our results of operations during the year ended December 31, 2024.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

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

As of December 31, 2024, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal

financial officer have concluded based upon the evaluation described above that, as of December 31, 2024, our disclosure controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for our company. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s principal executive officer and principal financial officer and effected by the company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of our company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our company’s assets that could have a material effect on the financial statements.

Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements prepared for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our principal executive officer and principal financial officer, assessed the effectiveness of our internal control over financial reporting as of December 31, 2024, based on criteria for effective internal control over financial reporting established in Internal Control — Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on its assessment, management concluded that our internal control over financial reporting was effective as of December 31, 2024, based on those criteria.

The effectiveness of our internal control over financial reporting as of December 31, 2024, has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting that occurred during the three months ended December 31, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Esperion Therapeutics, Inc.

Opinion on Internal Control Over Financial Reporting

We have audited Esperion Therapeutics, Inc.’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Esperion Therapeutics, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the balance sheets of the Company as of December 31, 2024 and 2023, the related statements of operations and comprehensive loss, stockholders’ deficit and cash flows for each of the three years in the period ended December 31, 2024, and the related notes and our report dated March 7, 2025, expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Financial Statements

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 and are struggling with elevated low density lipoprotein cholesterol ("LDL-C"). Through commercial execution, 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 to take recommended statin therapy (including those not taking a statin) with established cardiovascular disease ("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") 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. In addition, Otsuka Pharmaceutical Co., Ltd ("Otsuka"), Esperion’s Japanese collaborator, announced that the primary endpoint of LDL-C reduction from baseline at Week 12 was achieved with statistical significance in the Phase 3 clinical trial in Japan for bempedoic acid as a treatment for hypercholesterolemia. Otsuka filed a New Drug Application ("NDA") in Japan in November 2024, with expected approval and National Health Insurance ("NHI") pricing in the second half of 2025. The Company filed supplemental New Drug Applications for product approvals in Canada in November 2024 and the Company's collaboration partners plan to file in Australia and Israel in the first half of 2025.

The Company completed a global cardiovascular outcomes trial ("CVOT"), —known as Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen ("CLEAR") Outcomes. The trial was designed to evaluate whether treatment with bempedoic acid reduced the risk of cardiovascular events in patients who are statin averse and who have CVD or are at high risk for CVD. The Company initiated the CLEAR Outcomes CVOT in December 2016 and fully enrolled the study with nearly 14,000 patients in August 2019. The primary endpoint of the study was the effect of bempedoic acid on four types of major adverse cardiovascular events ("MACE") (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization; also referred to as "four-component MACE"). CLEAR Outcomes was an event-driven trial and concluded once the predetermined number of MACE endpoints occurred. The study showed that bempedoic acid demonstrated significant cardiovascular risk reductions and significantly reduced the risk of heart attack and coronary revascularization as compared to placebo. These results were seen in a broad population of primary and secondary prevention patients who are unable to maximize or tolerate a statin. The proportions of patients experiencing adverse events and serious adverse events were similar between the active and placebo treatment groups. Bempedoic acid, contained in NEXLETOL (bempedoic acid) tablets and NEXLIZET (bempedoic acid and ezetimibe) tablets, became the first LDL-C lowering therapy since statins proven to lower hard ischemic events, not only in those with atherosclerotic cardiovascular disease ("ASCVD") but also in the large number of primary prevention patients for whom limited therapies exist.

On January 2, 2024, the Company entered into a settlement agreement with Daiichi Sankyo Europe GmbH ("DSE") to amicably resolve and dismiss the commercial dispute then pending in the Southern District of New York ("Settlement Agreement"). Under the Settlement Agreement, DSE 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 received in the second quarter of 2024 after the European Medicines Agency ("EMA") rendered 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 tablets and NUSTENDI tablets in Europe. The legal action pending in the United States District Court for the Southern District of New York has now been dismissed. Refer to Note 3 "Collaborations with Third Parties" and Note 5 "Commitments and Contingencies" for further information.

On January 18, 2024, the Company entered into an Underwriting Agreement (the "Underwriting Agreement") with Jefferies LLC ("Jefferies"), as representative of several underwriters (the "Underwriters"), related to an underwritten public offering (the "January 2024 Offering") of 56,700,000 shares of Common Stock of the Company, par value $0.001 per share, at a purchase price to the public of $1.50 per share. The Underwriters were also granted a 30-day option to purchase up to an additional 8,505,000 shares of Common Stock, at the public offering price. On January 19, 2024, Jefferies gave notice to the Company of its election to exercise the option to purchase additional shares, in full. Giving effect to the exercise of

Underwriters' option, the January Offering closed on January 23, 2024, with proceeds to the Company of approximately $90.7 million, after deducting the underwriting discount and estimated offering expenses of $7.1 million.

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, and are now the only LDL-C lowering non-statin drugs indicated for primary prevention patients.

On May 22, 2024, the Company announced that the EC approved the label update of both NILEMDO and NUSTENDI as treatments for hypercholesterolemia and to reduce the risk of adverse cardiovascular events. The EC’s decisions to update the labels of bempedoic acid and the bempedoic acid / ezetimibe fixed dose combination are based on the positive CLEAR Outcomes trial results and makes them the first and only LDL-C lowering treatments indicated for primary and secondary prevention of cardiovascular events. NILEMDO and NUSTENDI are approved to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease.

On June 27, 2024, the Company entered into a Royalty Purchase Agreement (the “Purchase Agreement”) with OCM IP Healthcare Portfolio LP (“OMERS”), a limited partnership formed under the laws of the Province of Ontario, Canada (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 DSE and the Company, as amended (the “License and Collaboration Agreement” and such royalties being the “Royalty Interests”).

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. Refer to Note 11 "Sale of Future Royalties" for further information.

On June 27, 2024, the Company repurchased Revenue Interests outstanding under the Revenue Interest Purchase Agreement (the “RIPA”), dated effective as of June 26, 2019, as amended, by and among the Company, the purchasers party thereto (the “Purchasers”), and Eiger III SA LLC ("Oberland"), as the collateral agent and administrative agent (the “Purchaser Agent”), and satisfied all other Obligations (as defined in the RIPA) owed to the Purchasers and the Purchaser Agent by paying to the Purchaser Agent, for the benefit of the Purchasers, a payment in cash of $343.8 million (the “Repurchase Consideration”).Following the payment of the Repurchase Consideration, (a) all Revenue Interests were deemed to have been repurchased and all Obligations, debts and liabilities of the Company under the RIPA and the Transaction Documents (as defined in the RIPA) were deemed to have been paid and satisfied in full, and automatically released, discharged and terminated, and the RIPA and all other Transaction Documents automatically terminated, and all liens, security interests and pledges in favor of, granted to or held by the Purchaser Agent to secure the Obligations under the Transaction Documents were automatically terminated and released. Refer to Note 10 "Liability Related to the Revenue Interest Purchase Agreement" for further information.

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 (the “2025 Notes”) and to pay fees and expenses in connection with the Credit Agreement. Refer to Note 12 "Debt" for further information.

On December 13, 2024, the Company announced that they entered into privately negotiated exchange and subscription agreements, or the Agreements, with certain holders of our outstanding 2025 Notes. On December 17, 2024, the Company issued $100.0 million aggregate principal amount of 5.75% Convertible Senior Subordinated Notes due 2030 (the “2030 Notes”) under an Indenture, dated December 17, 2024 (the “Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee. The Company issued approximately $57.5 million aggregate principal amount of 2030 Notes along with approximately $153.4 million in cash, including accrued interest, in exchange for approximately $210.1 million aggregate principal amount of its 2025 Notes, pursuant to privately negotiated agreements entered into with certain holders of

its 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”). Refer to Note 12 "Debt" 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 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 near term future. While management believes current cash resources and future cash received from the Company's net product sales and collaboration agreements with DSE, Otsuka, and Daiichi Sankyo Co. Ltd ("DS"), 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 financial statements have been prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“GAAP”).

2. Summary of Significant Accounting Policies

Use of Estimates

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

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.

2. Summary of Significant Accounting Policies (Continued)

Investments

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

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

Cash, cash equivalents, and investments consist of financial instruments that potentially subject the Company to concentrations of credit risk. The Company has established guidelines for investment of its excess cash and believes the guidelines maintain safety and liquidity through diversification of counterparties and maturities. The Company enters into a limited number of distribution agreements with distributors and specialty pharmacies. The Company's net product sales are with these customers. As of December 31, 2024, ten customers accounted for all of the Company's net trade receivables and as of December 31, 2023 eleven customers accounted for all the Company's net trade receivables. As of December 31, 2024, three customers hold approximately 99% of the Company's trade receivables associated with net product sales and accounted for approximately 97% of gross sales of NEXLETOL and NEXLIZET in 2024.

Inventories, net

Inventoriesare 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.

Property and Equipment, Net

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

Leases

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

2. Summary of Significant Accounting Policies (Continued)

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment and right-of-use operating lease assets, for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. The impairment loss, if recognized, would be based on the excess of the carrying value of the impaired asset over its respective fair value. No impairment losses have been recorded through December 31, 2024.

Convertible Notes

The convertible notes are reported as a single liability at their amortized costs on the balance sheets, net of unamortized issuance costs. Issuance costs are amortized to interest expense over the life of the convertible debt. The Company uses the if-converted method when calculating diluted earnings per share.

Accrued Clinical Development Costs

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

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 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.

Revenue Interest Liability

The revenue interest liability is presented net of deferred issuance costs on the balance sheets. The Company imputes interest expense associated with this liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. The interest rate on the liability may vary during the term of the agreement depending on a number of factors, including the level of forecasted net sales. The Company evaluates the interest rate quarterly based on its current net sales forecasts utilizing the prospective method. In connection with the termination of the RIPA, as of December 31, 2024, the Company no longer has the liability referred to as the “Revenue interest liability” on the balance sheet.

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

2. Summary of Significant Accounting Policies (Continued)

obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when or as the performance obligation is satisfied. The Company derives revenue through two primary sources: collaboration revenue and product sales. Collaboration revenue consists of the collaboration payments to the Company for collaboration arrangements outside of the United States for the development, manufacturing and commercialization of the Company's product candidates by the Company's partners and product sales consists of sales of NEXLETOL and NEXLIZET 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. In accordance with ASC 606, revenue is measured as the amount of consideration expected to be entitled to in exchange for transferring promised goods or providing services to a customer. Revenue is recognized when (or as) the Company satisfies performance obligations under the terms of a contract. Depending on the terms of the arrangement, the Company may defer the recognition of all or a portion of the consideration received as the performance obligations are satisfied.

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 agreements typically include consideration to be provided to the Company in the form of non-refundable up-front payments, development milestones, sales milestones, and royalties on sales of products within a respective territory. The Company recognizes regulatory and approval milestones consideration when it is probable that a future reversal is unlikely to occur. For sales based milestones and royalties based on sales of product in a territory, the Company applies the sales-based royalty exception in ASC 606 to all of these milestones and royalties.

At the inception of a contract, the transaction price reflects the amount of consideration the Company expects to be entitled to in exchange for transferring promised goods or services to its customer. In the arrangement where the Company satisfies performance obligation(s) during the regulatory phase over time, the Company recognizes collaboration revenue typically using an input method on the basis of regulatory costs incurred relative to the total expected cost which determines the extent of progress toward completion. The Company reviews the estimate of the transaction price and the total expected cost each period, and makes revisions to such estimates as necessary. Under contracted supply agreements with collaborators, the Company may manufacture and supply quantities of active pharmaceutical ingredient (“API”) or bulk tablets reasonably required by collaboration partners for the development or sale of licensed products in their respective territory. The Company recognizes revenue when the collaboration partner has obtained control of the API or bulk tablets. The Company records the costs related to the supply agreement in cost of goods sold on the 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 March 30, 2020 and June 4, 2020, NEXLETOL and NEXLIZET, respectively, were commercially available in the U.S. through prescription and on June 4, 2020, NEXLIZET was commercially available in the U.S. through prescription. Net product sales totaled $115.7 million, $78.3 million and $55.9 million for the years ended December 31, 2024, December 31, 2023 and December 31, 2022, respectively.

The Company sells NEXLETOL and NEXLIZET to wholesalers in the U.S and 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 and fees. 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 balance sheets. Discounts, such as prompt pay discounts, and chargebacks are recorded as a reduction to trade accounts receivable in the 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 Medicare and 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 historical returns 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.

Cost of Goods Sold

Cost of goods sold is related to the Company's net product sales of NEXLETOL and NEXLIZET and the cost of the API and tablets supplied to collaboration partners under supply agreements. Cost of goods sold includes the actual product costs, including inbound freight charges and certain outbound freight charges, purchasing, sourcing, inspection and receiving costs.

Research and Development

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

Selling, General and Administrative Expenses

Selling, general and administrative expenses primarily consist of salaries and related costs for personnel, including stock-based compensation, associated with our sales, executive, accounting and finance, commercial, operational and other administrative functions. Other general and administrative expenses include costs of programs necessary for the general conduct of the Company's business, including costs associated with the commercialization of NEXLETOL and NEXLIZET, selling expenses, facility-related costs, communication expenses and professional fees for legal, patent prosecution, protection and review, consulting and accounting services. Selling, general and administrative expenses are expensed as costs are incurred, services are performed, or goods are delivered. The Company incurred advertising costs of $25.5 million, $15.6 million, and $11.3 million, for the years ended December 31, 2024, December 31, 2023 and December 31, 2022, respectively

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with the provisions of ASC 718, Compensation—Stock Compensation. Accordingly, compensation costs related to equity instruments granted are recognized over the requisite service periods of the awards on a straight-line basis at the grant-date fair value. The fair value for stock options and performance-based stock options is calculated using a Black-Scholes option-pricing model. The price used in the Black-Scholes model is determined by the closing stock price on the date of grant and adjusted if management identifies any material nonpublic information possessed at the time of grant. If the instruments contain performance conditions, compensation expense is recognized only if achievement of the performance condition is probable. The Company accounts for forfeitures as they occur. Expense is recognized during the period the related services are rendered.

Income Taxes

Deferred tax assets and liabilities are determined based on differences between financial reporting and the tax basis of assets and liabilities and are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company has incurred annual operating losses since inception. Accordingly, it is not more likely than not that the Company will realize a tax benefit from its deferred tax assets and as such, it has recorded a full valuation allowance.

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, Segment reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 will improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an interim and annual basis. This ASU is effective for annual periods beginning after December 15, 2023, and interim periods after December 15, 2024, with early adoption permitted. The Company adopted this standard for the year ended December 31, 2024 and it did not have a material impact on the Company's consolidated financial statements. Refer to Note 18 "Segment Reporting" for required disclosures from this ASU.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity's effective tax rate reconciliation, as well as information related to income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. This ASU will be effective for the annual period ending December 31, 2025. The Company is currently evaluating the timing and impacts of adoption of this ASU.

DSE Agreement Terms

On January 2, 2019, the Company entered into a license and collaboration agreement with DSE, which was further amended on June 18, 2020, and 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, Turkey and Switzerland (“DSE Territory”). DSE will be 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, included in the DSE Territory outside of Turkey.

Pursuant to the agreement, the Company received upfront cash of $150.0 million in 2019, and a $150.0 million cash payment to the Company in 2020 following the completion of the NUSTENDI Marketing Authorisation Applications ("MAA").

Finally, the Company will receive tiered fifteen percent (15%) to twenty-five percent (25%) royalties on net DSE Territory sales.

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

On January 2, 2024, the Company entered into a 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 million, including (1) a $100 million payment within 15 business days of the effective date of the Settlement Agreement and (2) a $25 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. 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.

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 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. Pursuant to the Otsuka Agreement, the Company granted Otsuka exclusive development and commercialization rights to NEXLETOL and NEXLIZET in Japan.

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

DS Agreement Terms

Pursuant to the license and collaboration agreement ("DS Agreement"), executed in April 2021, the Company granted DS exclusive rights to develop and commercialize bempedoic acid and the bempedoic acid / ezetimibe combination tablet in the DS Territory.

3. Collaborations with Third Parties (Continued)

Pursuant to the Settlement Agreement, on January 2, 2024, the Company entered a 1st Amendment (the “DS Amendment”) to the License and Collaboration Agreement with DS. The DS Amendment grants DS exclusive rights for clinical development, regulatory activities, manufacture and commercialization of a bempedoic acid/ezetimibe/statin triple combination pill in the DS Territory. Further, after a transition period, DS will assume sole responsibility for the manufacture of NILEMDO and NUSTENDI for the DS Territory.

Collaboration Revenue

The Company considered the guidance under ASC 606 and concluded that the DS Agreement was in the scope of ASC 606. The Company concluded that the upfront payment of $30.0 million should be included in the transaction price and related to the following performance obligations under the DS Agreement: 1) the license to the Company’s intellectual property and 2) the obligation to provide ongoing development activities. The Company used the adjusted market assessment approach in determining the standalone selling price of the Company’s intellectual property and the expected cost plus margin approach in determining the standalone selling price of the Company’s obligation to provide ongoing development activities. During the years ended December 31, 2023 and December 31, 2022, the Company recognized $0.7 million and $0.8 million, respectively, of collaboration revenue related to the ongoing regulatory and development activities.

Legal Proceedings

DSE Litigation

On March 27, 2023, the Company filed a complaint in the United States District Court for the Southern District of New York seeking declaratory judgment against DSE regarding the Company’s right to receive a $300.0 million milestone payment upon inclusion of cardiovascular risk reduction in the EU label that correlates with a relative risk reduction rate of at least 20%, based on the results of the CLEAR Outcomes CVOT.

On January 2, 2024, the Company entered into the Settlement Agreement with DSE to amicably resolve and dismiss the commercial dispute then pending in the Southern District of New York. Under the Settlement Agreement, DSE 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. The legal action pending in the United States District Court for the Southern District of New York has now been dismissed. Both milestones, totaling $125.0 million, were received in 2024 and included in collaboration revenue on the statements of operations.

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 (the “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 an affiliate); Dr. Reddy’s Laboratories Inc. (along with an affiliate); Hetero USA Inc. (along with affiliates); Micro Labs USA Inc. (along with an affiliate); MSN Pharmaceuticals Inc. (along with an affiliate); Renata Limited; and 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 trial is anticipated to begin no earlier than January 2027, but no trial date has been set.
