Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this report, including those set forth under Item 1A. “Risk Factors” and under “Forward-Looking Statements” in this Annual Report on Form 10-K.

Overview

Corporate Overview

We are a pharmaceutical company currently focused on developing and commercializing accessible, oral, once-daily, non-statin medicines for patients struggling with elevated low-density lipoprotein cholesterol, or LDL-C. Through commercial execution and completion of our CLEAR Outcomes trial as well as advancing our pre-clinical pipeline, we continue to evolve into a differentiated, global biotech. Our team of experts are dedicated to lowering LDL-cholesterol through the discovery, development and commercialization of innovative medicines and their combinations with established medicines. Our first two products were approved by the U.S. Food and Drug Administration, or FDA, European Medicines Agency, or EMA, and Swiss Agency for Therapeutic Products. or Swissmedic, in 2020. NEXLETOL® (bempedoic acid) and NEXLIZET® (bempedoic acid and ezetimibe) tablets are oral, once-daily, non-statin medicines for the treatment of primary hyperlipidemia in adults with heterozygous familial hypercholesterolemia, or HeFH or atherosclerotic cardiovascular disease, or ASCVD, who require additional lowering of LDL-C.

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 cardiovascular disease, or 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. On December 7, 2022, we announced that the study had met its primary endpoint.

On March 4, 2023, we announced the full results from the CLEAR Outcomes trial. 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 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 ASCVD but also in the large number of primary prevention patients for whom limited therapies exist.

On June 1, 2023, we announced that we submitted Supplemental New Drug Applications, or sNDAs, to the FDA seeking to add the use of both NEXLETOL and NEXLIZET for cardiovascular risk reduction and also seeking to remove the statin limitation in the LDL-C indication. Subsequently, the FDA accepted the sNDAs with an anticipated Prescription Drug User Fee Act date, or target action date, of March 31, 2024. On June 28, 2023, we announced that the application was filed for a Type II(a) variation with the EMA for our oral non-statin products marketed as NILEMDO® (bempedoic acid) tablets and NUSTENDI® (bempedoic acid and ezetimibe) tablets in Europe. The application asks EMA to approve both NILEMDO and NUSTENDI to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease. We anticipate EMA approval in the second quarter of 2024. On December 13, 2023, we announced that the FDA approved an updated LDL-cholesterol lowering indication for NEXLETOL and NEXLIZET to include the treatment of primary hyperlipidemia as a qualifier for existing approved populations. Additionally, the maximally tolerated qualifier for statin use has been removed, and the prior limitation of use stating “the effect of NEXLIZET or NEXLETOL on cardiovascular morbidity and mortality has not been determined” has also been removed.

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.

Table of Contents

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 and revenue interest purchase agreements. We have incurred losses in each year since our inception.

We have never been profitable and our net losses were $209.2 million and $233.7 million for the years ended December 31, 2023 and 2022, respectively. Substantially all of our net losses resulted from costs incurred in connection with research and development programs, selling, general and administrative costs associated with our operations. We expect to incur significant expenses and operating losses for the foreseeable 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 ACL, 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, cardiovascular disease demonstrated an average 21.1% 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 is currently indicated as an adjunct to diet and statin therapy for the treatment of primary hyperlipidemia in adults with HeFH or ASCVD who require additional lowering of LDL-C.

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

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

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

During the 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 was commercially available in the U.S. on March 30, 2020 and NEXLIZET was commercially available in the U.S. on June 4, 2020.

Collaboration revenue

Collaboration revenue is related to our collaboration agreements with Daiichi Sankyo and Otsuka. Collaboration revenue in the years ended December 31, 2023 and December 31, 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.

Cost of Goods Sold

Cost of goods sold is related to our net product sales of NEXLETOL and NEXLIZET and the cost of goods sold from our supply agreements with collaboration partners.

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, 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. 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 decrease substantially in 2024 after the completion of the CLEAR Outcomes CVOT and submitting regulatory filings to the FDA and EMA in 2023. 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. 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

Table of Contents

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

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

We expect our selling, general and administrative expenses will increase in 2024 in anticipation of potential additional global regulatory approvals for new product indications, expanded commercialization initiatives for NEXLETOL and NEXLIZET, and increases in our associated headcount to expand our sales team.

Interest Expense

Interest expense for the years ended December 31, 2023 and December 31, 2022 was related to our Revenue Interest Purchase Agreement, or RIPA, with Eiger III SA LLC, or Oberland, an affiliate of Oberland Capital, and our convertible notes.

Other Income

Other income, net, for the years ended 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 collaboration agreements and revenue interest liability. We base our estimates on historical experience, known trends and events, contractual milestones and other various factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions.

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, 2023 net product sales would have an impact of approximately $2.4 million.

Revenue Interest Liability

We have entered into a RIPA to support the commercialization and further development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and provide for other working capital needs. The revenue interest liability related to the RIPA 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 and is presented as interest expense on the statements of operations. 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. This estimate is complex and highly judgmental as it is based on our future revenue projections and expectations about future economic and market conditions. We evaluate the interest rate quarterly based on our current net sales forecasts utilizing the prospective method. A significant increase or decrease in net sales will materially impact the revenue interest liability, interest expense and the time period for repayment. Under the terms of the RIPA, every $100 million of net sales generated, less than or equal to $250 million in an annual aggregate year, would result in a repayment obligation of approximately $10.0 million or 10.0% at the stated repayment rate in the first year. Annual net sales for a calendar year exceeding $250 million would result in a repayment obligation of approximately $3.3 million or 3.3% for every $100 million of sales above the threshold. In 2025, the percent of net revenue paid to Oberland could reset to a higher amount if certain revenue milestones are not met. This could result in substantially higher payments starting in 2025. Issuance costs in connection with the RIPA are amortized to interest expense over the estimated term of the RIPA.

Comparison of the Years Ended December 31, 2023 and 2022

The following table summarizes our results of operations for the years ended December 31, 2023 and 2022:

Year Ended December 31,

(in thousands)

Revenues:

Operating Expenses:

Product sales, net

Product sales, net for the year ended December 31, 2023 was $78.3 million compared to $55.9 million for the year ended December 31, 2022, an increase of approximately $22.4 million. The increase is primarily due to prescription growth of NEXLETOL and NEXLIZET.

Collaboration revenue

Collaboration revenue recognized from our collaboration agreements for the year ended December 31, 2023 was $38.0 million compared to $19.6 million for the year ended December 31, 2022, an increase of $18.4 million. The increase is primarily due to increased product sales to our collaboration partners from our supply agreements and royalty sales growth within our partner territories.

Cost of goods sold

Cost of goods sold for the year ended December 31, 2023, was $43.3 million compared to $27.0 million for the year ended December 31, 2022, an increase of $16.3 million. The increase is primarily related to increased product sales to our collaboration partners under our supply agreements and increased net product sales of NEXLETOL and NEXLIZET.

Research and development expenses

Research and development expenses for the year ended December 31, 2023, were $86.1 million compared to $118.9 million for the year ended December 31, 2022, a decrease of $32.8 million. The decrease in research and development expenses was primarily attributable to a decrease in costs related to CLEAR Outcomes study following the announcement and presentation of our CLEAR Outcomes study results in March 2023. Costs incurred in the year ended December 31, 2023 included the announcement and presentation of our CLEAR Outcomes study results, associated close-out activities and regulatory submissions.

Selling, general and administrative expenses

Selling, general and administrative expenses for the year ended December 31, 2023, were $142.5 million compared to $109.1 million for the year ended December 31, 2022, an increase of $33.4 million. The increase in selling, general and administrative expenses was primarily attributable to increases in legal costs, including legal costs associated with the settlement announced in early January 2024, increases in headcount, consulting and other promotional related expenses.

Table of Contents

Interest expense

Interest expense for the year ended December 31, 2023, was $59.0 million, compared to $56.8 million for the year ended December 31, 2022, an increase of $2.2 million. The increase in interest expense for the year ended December 31, 2023 was primarily due to additional interest expense attributable to our RIPA with Oberland.

Other income, net

Other income, net for the year ended December 31, 2023, was $5.3 million compared to $2.7 million for the year ended December 31, 2022, an increase of $2.6 million. This increase was primarily due to higher interest income on our investments due to higher interest rates.

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 purchase agreement. 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 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 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 March 19, 2023, we entered into a Securities Purchase Agreement, pursuant to which we agreed to issue and sell, in a registered direct offering, or the Registered Direct Offering, 12,205,000 shares of our common stock, pre-funded warrants 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 Securities Purchase Agreement, 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 and expire three and one half years following the closing of the Registered Direct Offering, for additional consideration of $0.125 per amended warrant. We received net proceeds of approximately $51.3 million related to the Registered Direct Offering and approximately $1.1 million in connection with the amended warrants.

On January 2, 2024, we entered into a settlement agreement with Daiichi Sankyo Europe GmbH, or DSE, to amicably resolve and dismiss the commercial dispute then pending in the Southern District of New York, or the Settlement Agreement. Under the Settlement Agreement, DSE agreed to pay us 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 our oral non-statin products marketed as NILEMDO® (bempedoic acid) tablets and NUSTENDI® (bempedoic acid and ezetimibe) tablets in Europe. The application asks the EMA to approve both NILEMDO and NUSTENDI to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease. 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 an underwriting agreement, or the Underwriting Agreement, with Jefferies LLC, or Jefferies, as representative of several underwriters, or the Underwriters, related to an underwritten public offering, or the January 2024 Offering, of 56,700,000 shares of our common stock, 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 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 offering proceeds to us were approximately $90.8 million, after deducting the underwriting discount and estimated offering expenses. The January 2024 Offering closed on January 23, 2024.

Table of Contents

We anticipate that we will incur operating losses for the foreseeable 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, cash equivalents, and investments, including the funds received in January 2024 from the Settlement Agreement and January 2024 Offering, expected future net product sales of NEXLETOL and NEXLIZET, and expected future revenue under our collaboration agreements is sufficient to fund continuing operations for the foreseeable future.

As of December 31, 2023, our primary sources of liquidity were our cash and cash equivalents which totaled $82.2 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 provided by investing activities 42,500 8,104

Net cash provided by financing activities 50,460 32,606

Net decrease in cash, cash equivalents and restricted cash (42,527) (134,117)

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.

Net cash used in operating activities totaled $135.5 million for the year ended December 31, 2023 and $174.8 million for the year ended December 31, 2022, consisting 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, 2023 compared to the year ended December 31, 2022 was primarily related to a decrease in net loss from increases in net product sales and collaboration revenue and lower research and development costs from our CLEAR Outcomes CVOT following the public presentation of the results in 2023, partially offset by increase in selling, general, and administrative expenses due to increased legal costs and other promotional expenses, 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 provided by investing activities of $42.5 million for the year ended December 31, 2023 and $8.1 million for the year ended December 31, 2022 consisted primarily of net proceeds from the sales of highly liquid, interest bearing investment grade and government securities.

Financing Activities

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, exercise of warrants, and net proceeds from our 2023 ATM Program, partially offset by payments on our revenue interest liability. Net cash provided by financing activities of $32.6 million for the year ended December 31, 2022, related primarily proceeds from our 2022 ATM Program, partially offset by a one-time partial call payment with regards to the Revenue Interests (as defined in the RIPA) in an amount equal to $50.0 million from the restricted cash account under the waiver and amendment of our RIPA with Oberland, and payments on our revenue interest liability.

Table of Contents

In 2019, we entered into a RIPA with Oberland. Pursuant to the RIPA, Oberland paid us $125.0 million at closing, less certain issuance costs, and, subject to the terms and conditions of the RIPA, we received an additional $25.0 million upon regulatory approval of NEXLETOL in 2020 and were eligible to receive an additional $50.0 million at our option upon reaching certain sales thresholds. In April 2021, we entered into Amendment No. 2 to the RIPA and Oberland waived the original trailing six-month world-wide net sales condition to the third installment payment under the RIPA and released the final $50 million payment payable to us under the terms of the RIPA. The amendment also updated the tiered payment percentage. As the quarterly net revenue from sales of NEXLETOL and NEXLIZET and certain other products in the United States did not exceed $15.0 million for the quarter ended September 30, 2021, we deposited $50.0 million in a deposit account with Oberland, which reduced our unrestricted cash. On November 23, 2022, we entered into a waiver and amendment to the RIPA with Oberland, in which we agreed to make a one-time partial call payment with regards to the Revenue Interests (as defined in the RIPA) in an amount equal to $50 million from the restricted cash account (the “Partial Call”). Under this amendment, the amount of the Cumulative Purchaser Payments (as defined in the RIPA) was reduced to $177,777,778. As consideration for the payments, Oberland has the right to receive certain revenue interests from us based on the net sales of certain products which will be tiered payments ranging from 3.3% to 10% of our net sales in the covered territory (as detailed in the RIPA). Esperion reacquires 100% revenue rights upon repayment completion. We recorded the proceeds from the RIPA as a liability on the balance sheets and are accounting for the RIPA under the effective-interest method over the estimated life of the RIPA. Future payments under the RIPA may range from $34.8 million in the next year to a maximum total payment of $337.8 million beyond one year. Per the terms of the agreement, every $100 million of net sales generated, less than or equal to $250 million in an annual aggregate, would result in a repayment obligation of approximately $10.0 million or 10% at the stated repayment rate in the first year. In the future, as net sales thresholds set forth in the agreement are met and the repayment percentage rate changes, the amount of the obligation and timing of payment is likely to change. In 2025, the percent of net revenue paid to Oberland could reset to a higher amount if certain revenue milestones are not met. This could result in substantially higher payments starting in 2025. As the U.S. net sales were less than $350 million for the year ended December 31, 2021, the Covered Territory was expanded to include worldwide sales beginning in 2022. A significant increase or decrease in net sales will materially impact the revenue interest liability, interest expense and the time period for repayment. Refer to Note 10 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

On November 16, 2020, we issued $250.0 million aggregate principal amount of 4.00% convertible senior subordinated notes due 2025 to certain financial institutions as the initial purchasers of the convertible notes. An additional $30.0 million of additional convertible notes (collectively, the "Convertible Notes"), which were issued pursuant to the exercise of the initial purchasers' option to purchase such convertible notes, closed on November 18, 2020. On October 22, 2021, we entered into the Exchange Agreement with the Holders, of our Convertible Notes. Under the terms of the Exchange Agreement the Holders agreed to exchange with us $15.0 million aggregate principal amount of the Convertible Notes held in the aggregate by them (and accrued interest thereon) for shares of our common stock, which closed on November 3, 2021. Future payments under the convertible notes include annual interest of $10.6 million and a principal payment of $265.0 million in 2025. Refer to Note 11 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K.

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. During the year ended December 31, 2022, we issued 13,043,797 shares of common stock, pursuant to the 2022 ATM Program for which Jefferies LLC served as sales agent, resulting in net proceeds of approximately $90.8 million after deducting $3.1 million of underwriting discounts and commissions and other expenses. 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, 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.

As noted above, on March 22, 2023, we issued and sold, in a registered direct offering, or the Registered Direct Offering, 12,205,000 shares of our common stock, pre-funded warrants to purchase up to an aggregate of 20,965,747 shares of our common stock, 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, 2023, no pre-funded warrants were outstanding. 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. 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 12 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K for further information.

As noted above, subsequent to December 31, 2023, we received $100 million from DSE in January 2024 under the Settlement Agreement and expect to receive $25 million 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 our oral non-statin products marketed as NILEMDO tablets and NUSTENDI tablets in Europe. In addition, as noted above, we received approximately $90.8 million, after deducting the underwriting discounts and estimated offering expenses, from our January 2024 Offering.

Plan of Operations and Funding Requirements

We expect to continue to incur significant expenses and operating losses for the foreseeable future in connection with our 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, including cash received in January 2024 in conjunction with Settlement Agreement with DSE and the January 2024 Offering, 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;

•the time and cost necessary to obtain regulatory approvals for bempedoic acid and the bempedoic acid / ezetimibe combination tablet outside the U.S. and Europe and regulatory approvals for cardiovascular risk reduction in the U.S. and Europe;

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

•our ability to realize the intended benefits of our existing and future collaboration and partnerships, 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, permitted debt financings, permitted royalty-based financings and equity offerings or other sources. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing, if available and permitted under the terms of our RIPA, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with pharmaceutical partners or royalty-based financing arrangements, such as the collaboration arrangement with DSE, Otsuka and DS, and the

Table of Contents

RIPA with Oberland, we may have to relinquish valuable rights to our technologies, future revenue streams or grant licenses on terms that may not be favorable to us. For instance, as part of the RIPA with Oberland, Oberland has the right to receive certain revenue interests from us based on the net sales of certain products, and we have granted Oberland a senior security interest in certain of our assets. If our cash flows and capital resources are insufficient to allow us to make required payments, we may have to reduce or delay capital expenditures, sell assets or seek additional capital. If we raise funds by selling additional equity, such sale would result in dilution to our stockholders. If we are unable to raise additional funds through equity or permitted debt financings or through collaborations, strategic alliances or licensing arrangements or permitted royalty-based financing arrangements when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market bempedoic acid and the bempedoic acid / ezetimibe combination 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.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

We had cash and cash equivalents of approximately $82.2 million at December 31, 2023. 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 operation. 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, 2023.

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.

We have entered into a revenue interest purchase agreement. Our primary exposure to market risk is that 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. A significant increase or decrease in net sales will materially impact the revenue interest liability, interest expense and the time period for repayment. Our Convertible Notes, which were issued in November 2020, carry a fixed interest rate of 4.0% per year. Since the Convertible Notes 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, 2023.

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 Securities and Exchange Act of 1934 is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our President and Chief Executive Officer, who is our principal executive officer, and our Chief Financial Officer, who is our principal financial officer, to allow timely decisions regarding required disclosure.

As of December 31, 2023, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of December 31, 2023, 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, 2023, 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, 2023, based on those criteria.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm regarding our internal control over financial reporting. We are not required to have, nor have we engaged our independent registered public accounting firm to perform, an audit on our internal control over financial reporting pursuant to the rules of the SEC that permit us to provide only management’s report in this Annual Report on Form 10-K.

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, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

We did not have any Rule 10b5-1 plans in place during the year ended December 31, 2023.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Esperion Therapeutics, Inc. (the Company) as of December 31, 2023 and 2022, the related statements of operations and comprehensive loss, stockholders' equity (deficit) and cash flows for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosure to which it relates.

Notes to Financial Statements

1. The Company and Basis of Presentation

Esperion Therapeutics, Inc. ("the Company”) is a pharmaceutical company currently focused on developing and commercializing accessible, oral, once-daily, non-statin medicines for patients struggling with elevated low density lipoprotein cholesterol ("LDL-C"). Through commercial execution and completion of the CLEAR Outcomes trial as well as advancing the Company's pre-clinical pipeline, the Company continues to evolve into a differentiated, global biotech. The Esperion team of experts are dedicated to lowering LDL-cholesterol through the discovery, development and commercialization of innovative medicines and their combinations with established medicines. The Company's first two products were approved by the U.S. Food and Drug Administration ("FDA"), European Medicines Agency ("EMA") and Swiss Agency for Therapeutic Products ("Swissmedic") in 2020. NEXLETOL® (bempedoic acid) and NEXLIZET® (bempedoic acid and ezetimibe) tablets are oral, once-daily, non-statin medicines for the treatment of primary hyperlipidemia in adults with heterozygous familial hypercholesterolemia ("HeFH") or atherosclerotic cardiovascular disease ("ASCVD"), who require additional lowering of LDL-C.

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 cardiovascular disease ("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. On December 7, 2022, the Company announced that the study had met its primary endpoint.

On March 4, 2023, the Company announced the full results from the CLEAR Outcomes trial. 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 ASCVD but also in the large number of primary prevention patients for whom limited therapies exist.

On March 19, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain purchasers named therein (the “Purchasers”), pursuant to which the Company agreed to issue and sell, in a registered direct offering (the “Registered Direct Offering”), 12,205,000 shares of its common stock, par value $0.001 per share (the “Common Stock”), pre-funded warrants to purchase up to an aggregate of 20,965,747 shares of Common Stock (the “Pre-Funded Warrants”) in lieu of shares of Common Stock, and warrants to purchase up to 33,170,747 shares of Common Stock (the “Warrants”). The combined purchase price of each share of Common Stock and accompanying Warrant is $1.675 per share. The purchase price of each Pre-Funded Warrant and the accompanying Warrant is $1.674 (equal to the combined purchase price per share of Common Stock and accompanying Warrant, minus $0.001). The Purchase Agreement contains customary representations, warranties, covenants and indemnification rights and obligations of the Company and the Purchasers. The Registered Direct Offering closed on March 22, 2023. In connection with the Registered Direct Offering, the Company amended, pursuant to Warrant Amendment Agreements (the “Warrant Amendment Agreements”), certain existing warrants to purchase up to an aggregate of 9,024,212 shares of the Company's common stock that were previously issued in December 2021 at an exercise price of $9.00 per share and had an expiration date of December 7, 2023, effective upon the closing of the Registered Direct Offering, such that the amended warrants have a reduced exercise price of $1.55 per share and expire three and one half years following the closing of the Registered Direct Offering, for additional consideration of $0.125 per amended warrant. The Company received gross proceeds of approximately $55.5 million from the Registered Direct Offering, before deducting placement agent fees and related offering expenses. The net proceeds to the Company from the Registered Direct Offering, after deducting the placement agent fees and expenses and the Company’s estimated offering expenses, are approximately $51.3 million. In addition, the Company received approximately $1.2 million as the gross consideration in connection with the Warrant Amendment Agreements. The net proceeds of the Warrant Amendment Agreements after deducting placement fees were approximately $1.1 million. Refer to Note 12 "Stockholders' Deficit" for further information.

1. The Company and Basis of Presentation (Continued)

On June 1, 2023, the Company announced that it submitted Supplemental New Drug Applications ("sNDAs") to the FDA seeking to add the use of both NEXLETOL and NEXLIZET for cardiovascular risk reduction and also seeking to remove the statin limitation in the LDL-C indication. Subsequently, the FDA accepted the sNDAs with an anticipated Prescription Drug User Fee Act date, or target action date, of March 31, 2024. On June 28, 2023, the Company announced that the application was filed for a Type II(a) variation with the EMA for the Company’s oral non-statin products marketed as NILEMDO® (bempedoic acid) tablets and NUSTENDI® (bempedoic acid and ezetimibe) tablets in Europe. The application asks EMA to approve both NILEMDO and NUSTENDI to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease. The Company anticipates EMA approval in the second quarter of 2024.

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 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 application asks the EMA to approve both NILEMDO and NUSTENDI to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease. 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," Note 5 "Commitments and Contingencies," and Note 18 "Subsequent Events" 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 (“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 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 offering proceeds to the Company were approximately $90.8 million, after deducting the underwriting discount and estimated offering expenses. The January 2024 Offering closed on January 23, 2024.

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 foreseeable future. While management believes current cash resources, including the cash received in January 2024 as disclosed in Note 18 "Subsequent Events," and future cash received from the Company's net product sales and collaboration agreements with DSE, Otsuka Pharmaceutical Co., Ltd ("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.

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.

Cash and Cash Equivalents

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

Restricted Cash

Restricted cash consists of legally restricted amounts held by financial institutions pursuant to contractual arrangements. Pursuant to the Amendment and Waiver (as defined below), in 2021 the Company deposited $50.0 million in a deposit account that was subject to a block account control agreement. Oberland had the sole control over the funds deposited in the account and such funds could be withdrawn only with the consent of Eiger III SA LLC, or Oberland, an affiliate of Oberland Capital LLC. On November 23, 2022, pursuant to the Waiver and Amendment No. 3, the Company agreed to make a one-time partial call payment with regards to the Revenue Interests, as defined in the Revenue Interest Purchase Agreement ("RIPA"), in the amount of $50.0 million, the full amount that was subject to the block account control agreement. Refer to Note 10 "Liability Related to the Revenue Interest Purchase Agreement" for further information on the Amendment and Waiver.

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.

Selling, General and Administrative Expenses

Selling, general and administrative expenses primarily consist of salaries and benefits, stock-based compensation, and costs of programs necessary for the general conduct of the Company's business, including costs associated with the commercialization of NEXLETOL and NEXLIZET in the U.S. Selling, general and administrative expenses are expensed as costs are incurred, services are performed, or goods are delivered. The Company incurred advertising costs of $15.6 million and $11.3 million for the years ended December 31, 2023 and December 31, 2022, respectively.

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, 2023, eleven customers accounted for all of the Company's net trade receivables and as of December 31, 2022 eleven customers accounted for all the Company's net trade receivables. As of December 31, 2023, three customers hold approximately 96% of the Company's trade receivables associated with net product sales and accounted for approximately 95% of gross sales of NEXLETOL and NEXLIZET in 2023.

2. Summary of Significant Accounting Policies (Continued)

Inventories

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.

Segment Information

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

Fair Value of Financial Instruments

The Company’s cash, cash equivalents, and investments 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.

Property and Equipment, Net

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

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment 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, 2023.

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.

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.

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.

Revenue Recognition

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

F-12

Notes to Financial Statements (Continued)

2. Summary of Significant Accounting Policies (Continued)

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 income (loss).

Under the Company's collaboration agreements, product sales and cost of sales may be recorded by the Company's collaborators as they are deemed to be the principal in the transaction. The Company receives royalties from the commercialization of such products, and records its share of the variable consideration, representing a percentage of net product sales, as collaboration revenue in the period in which such underlying sales occur and costs are incurred by the collaborators.

b.Product Sales, Net

On March 30, 2020, NEXLETOL was commercially available in the U.S. through prescription and on June 4, 2020, NEXLIZET was commercially available in the U.S. through prescription. Net product sales totaled $78.3 million and $55.9 million for the years ended 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.

Notes to Financial Statements (Continued)

2. Summary of Significant Accounting Policies (Continued)

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.

Accrued Clinical Development Costs

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

Income Taxes

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.

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. 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.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Segment Reporting Disclosures. This standard requires an entity to provide more detailed information about its reportable segment expenses that are included within management’s measurement of profit and loss and will require certain annual disclosures to be provided on an interim basis. The amendments in this ASU are effective for the Company in 2025 for annual reporting and in 2026 for interim reporting, with early adoption permitted beginning in 2024, and is required to be applied using the full retrospective method of transition. The Company is evaluating the timing and effects of adoption of this ASU on the Company’s segment disclosures.

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.

The Company does not expect adoption of any remaining recently issued accounting pronouncements to have a material impact on the financial statements.

3. Collaborations with Third Parties

DSE Agreement Terms

On January 2, 2019, the Company entered into a license and collaboration agreement with DSE, which was further amended on June 18, 2020. Pursuant to the agreement (as amended), 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"). The Company is responsible for supplying DSE with certain manufacturing supply of the API or bulk tablets. In addition, the Company is eligible to receive additional sales milestone payments related to total net sales achievements for DSE in the DSE Territory. Finally, the Company 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. Further, after a transition period, DSE will assume sole responsibility for the manufacture of NILEMDO and NUSTENDI for the DSE Territory. As of January 2, 2024, DSE shall have sole authority and control of regulatory communications with the EMA regarding the pending marketing authorization applications for NILEMDO and NUSTENDI. Pursuant to the DSE Amendment, the Company is entitled to receive one-time cash payments of up to $300 million upon the achievement of certain commercial

milestones related to total net sales achievements in the DSE Territory. The Company is also entitled to receive tiered 15% to 25% royalties on net DSE Territory sales.

Collaboration Revenue

During the years ended December 31, 2023 and December 31, 2022, the Company recognized collaboration revenue of $37.2 million and $18.2 million, respectively, related to royalty revenue from DSE as well as the sales of bulk tablets to DSE pursuant to the supply agreement that was executed with DSE.

All remaining future potential milestone amounts were not included in the transaction price, as they were all determined to be fully constrained following the concepts of ASC 606 due to the fact that such amounts hinge on development activities, regulatory approvals and sales-based milestones. Additionally, the Company expects that any consideration related to 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. Otsuka will be responsible for all development, regulatory, and commercialization activities in Japan. In addition, Otsuka will fund all clinical development costs associated with the program in Japan.

Pursuant to the agreement, the consideration consists of a $60.0 million upfront cash payment and the Company will be eligible to receive additional payments of up to $450.0 million if certain regulatory and commercial milestones are achieved by Otsuka. The potential future milestone payments include up to $20 million upon first JNDA submissions in the Otsuka Territory, up to $70.0 million upon the first NHI Price Listing for NEXLETOL in the Otsuka Territory, and up to $50.0 million upon the achievement of the primary major adverse cardiovascular events (“MACE”) in the CLEAR Outcomes study and inclusion of the CV risk reduction indication in the U.S. label, depending on the range of relative risk reduction in the CLEAR Outcomes study. In addition, the Company is eligible to receive additional sales milestone payments up to $310.0 million related to total net sales achievements for Otsuka in Japan. Finally, the Company will receive tiered fifteen percent (15%) to thirty percent (30%) royalties on net sales in Japan.

Collaboration Revenue

During the years ended December 31, 2023, and December 31, 2022, the Company recognized collaboration revenue of $0.1 million and $0.6 million, respectively, related to sales of bulk tablets to Otsuka pursuant to the supply agreement that was executed with Otsuka.

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

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

3. Collaborations with Third Parties (Continued)

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. The agreement allows for potential expansion across geographies including Saudi Arabia, Kuwait, Oman, UAE, Qatar, Bahrain, Yemen, Colombia and other Latin American countries. Except for certain development activities in South Korea and Taiwan, DS will be responsible for development and commercialization in these territories. In addition, DS will fund all development costs associated with the program in the DS Territory. Pursuant to the agreement, the consideration consists of a $30.0 million upfront cash payment that is non-refundable, non-reimbursable and non-creditable. The Company will be eligible to receive additional one-time payments of up to $175.0 million if certain commercial milestones are achieved by DS. Also, the Company will receive tiered royalties of five percent (5%) to twenty percent (20%) of net sales in the DS Territory.

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.

Other Agreements

In December 2020, the Company entered into a licensing agreement with Serometrix to in-license a series of early stage compounds known as scaffolds related to its oral, small molecule PCSK9 inhibitor program. The agreement allowed the Company use of the PCSK9 compounds, which were patented by Serometrix prior to the licensing agreement, to perform further research and development with the goal of developing a small molecule oral PCSK9 inhibitor that can be taken as a tablet. On July 6, 2023, the Company provided notice to Serometrix of its intent to terminate the licensing agreement between the Company and Serometrix dated December 3, 2020. The agreement terminated as of August 5, 2023. The Company expects to continue to advance its internal pipeline assets, including next-generation ACLY inhibitors.

Legal Proceedings

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 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 May 4, 2023, the Company filed an amended complaint against DSE in the Southern District of New York seeking a judicial declaration, on an expedited basis, that DSE is contractually required to make a $300 million milestone payment to the Company upon applicable regulatory approval. On June 20, 2023, DSE filed a response to the amended complaint.

On January 2, 2024, the Company entered into a settlement agreement with DSE to amicably resolve and dismiss the commercial dispute then pending in the Southern District of New York, or the Settlement Agreement. Under the Settlement Agreement, DSE 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 application asks the EMA to approve both NILEMDO and NUSTENDI to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease. The legal action pending in the United States District Court for the Southern District of New York has now been dismissed.

Pursuant to the Settlement Agreement, also on January 2, 2024, the Company entered into a 3rd Amendment to the License and Collaboration Agreement dated January 2, 2019 with DSE, and a 1st Amendment to the License and Collaboration Agreement dated April 26, 2021 with DS. Each of these amendments grant each of DSE and DS exclusive rights for clinical development, regulatory activities, manufacture and commercialization of a bempedoic acid/ezetimibe/statin triple combination pill in their existing respective territories of the European Economic Area, UK, Switzerland and Turkey (the “DSE Territory”) and South Korea, Taiwan, Hong Kong, Thailand, Vietnam, Brazil, Macao, Cambodia and Myanmar (the “DS Territory”). Further, after a transition period, DSE and DS will assume sole responsibility for the manufacture of NILEMDO and NUSTENDI for, respectively, the DSE Territory and DS Territory. As of January 2, 2024, DSE shall have sole authority and control of regulatory communications with the EMA regarding the pending marketing authorization applications for NILEMDO and NUSTENDI.

9. Fair Value Measurements

The Company follows accounting guidance that emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” Fair value measurements are defined on a three level hierarchy:

10. Liability Related to the Revenue Interest Purchase Agreement

On June 26, 2019, the Company entered into a RIPA with Oberland, as agent for purchasers party thereto (the “Purchasers”), and the Purchasers named therein, to obtain financing in respect to the commercialization and further development of bempedoic acid and the bempedoic acid / ezetimibe combination tablet and other working capital needs. Pursuant to the RIPA, the Company received $125.0 million at closing, less certain issuance costs. The Company was entitled to receive up to approximately $75.0 million in subsequent installments subject to the terms and conditions set forth in the RIPA: (i) $25.0 million upon certain regulatory approval of its product candidates and (ii) $50.0 million, at the Company’s option, upon reaching $100.0 million trailing worldwide six-month net sales any time prior to December 31, 2021 (the “Third Payment”). In March 2020, the Company received $25.0 million from Oberland upon receiving regulatory approval of NEXLETOL.

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

Under the RIPA, the Company has an option (the “Call Option”) to terminate the RIPA and repurchase future Revenue Interests at any time upon advance written notice. Additionally, the Purchasers have an option (the “Put Option”) to terminate the RIPA and to require the Company to repurchase future Revenue Interests upon enumerated events such as a bankruptcy event, an uncured material breach, a material adverse effect or a change of control.

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

RIPA Amendments

On April 26, 2021, the Company entered into Amendment No. 2 (the “RIPA Amendment 2”) to the RIPA with Oberland, as agent for the purchaser parties thereto. Pursuant to the RIPA Amendment 2, Oberland waived the original trailing six-month world-wide net sales condition to the third installment payment under the RIPA and released the final $50 million payment payable to the Company under the terms of the RIPA. The Company and Oberland also agreed to amend additional terms of the RIPA such that the purchasers will have a right to receive certain revenue interests (the “Revenue Interests”) from the Company based on net sales of the Company’s certain products, once approved, which will be tiered payments ranging from 3.33% to 10% (the “Third Payment Applicable Percentage”) of the Company’s net sales in the covered territory (the “Covered Territory”); provided that (a) prior to December 31, 2024, with respect to each country defined in the Daiichi Territory, if the percentage of net sales that Company receives from Daiichi (the “Receivables Percentage”) is less than the Third Payment Applicable Percentage, then the Revenue Interest for such country payable to the purchasers will be equal to the Receivables Percentages, (b) if annual net sales equal or exceed $350 million and if the Purchasers receive 100% of their invested capital (Cumulative Purchaser Payments") by December 31, 2024, the revenue interest rate will be decreased to a single rate of 3.33% of the Company’s net sales in the Covered Territory for all subsequent calendar quarters and (c) if the Purchasers receive Revenue Interest payments less than 100% of Cumulative Purchaser Payments by December 31, 2024, the Third Payment Applicable Percentage will be increased to a single rate of the Company’s net sales that would have provided 100% of Cumulative Purchaser Payments had such rate applied from the initial funding by the Purchasers. The Covered Territory was originally the United States, but has been expanded to worldwide for all calendar years beginning on or after January 1, 2022.

Under the RIPA Amendment 2, the Company has an option (the “Call Option”) to terminate the RIPA and repurchase future Revenue Interests at any time upon advance written notice. Additionally, the Purchasers have an option (the “Put Option”) to terminate the RIPA and to require the Company to repurchase future Revenue Interests upon enumerated events such as a bankruptcy event, an uncured material breach, a material adverse effect or a change of control. If the Put Option or the Call Option are exercised, the required repurchase price will be 200% of the Cumulative Purchaser Payments (minus all payments Company has made to the Purchasers in connection with the Revenue Interests), if such option is exercised prior to the third anniversary of the closing date, and 225% of the Cumulative Purchaser Payments (minus all payments Company has made to the Purchasers in connection with the Revenue Interests), if such option is exercised thereafter.

On May 16, 2021, the Company entered into an Amendment to the Security Agreement and Waiver ("Amendment and Waiver") with the same parties to the Security Agreement, by and among the Company, Eiger Partners II LP (the "Purchaser") and Eiger III SA LLC (the "Purchaser Agent"), dated as of June 26, 2019 (the "Security Agreement"). Pursuant to the Amendment and Waiver, if (i) the net revenue from sales of NEXLETOL and NEXLIZET and certain other products in the United States (as reported in the Company’s financial statements as “product sales, net” in accordance with GAAP and excluding, for the avoidance of doubt, upfront or milestone payments and other collaboration revenue) (the “Specified Net Revenue”) for the calendar quarter ended September 30, 2021 does not exceed $15.0 million, or (ii) the Specified Net Revenue for any calendar quarter ending after September 30, 2021 does not exceed $15.0 million, then the Company shall deposit $50.0 million in a deposit account that is subject to a block account control agreement in favor of the Purchase Agent, no later than the earlier of (x) the date the Specified Net Revenue for such calendar quarter has been determined and (y) 45 days after the last day of such calendar quarter. Since the Specified Net Revenue for the calendar quarter ended September 30, 2021 did not exceed $15.0 million, the Company deposited $50.0 million in a deposit account that is subject to a block account control agreement, which is classified as restricted cash on the balance sheets. The Purchaser Agent shall have sole dominion and control over all funds deposited in the deposited account and such funds may be withdrawn therefrom only with the consent of the Purchaser Agent. Upon the occurrence and during the continuance of a Put Option Event, the Purchaser Agent shall have the right to apply amounts held in the deposit account in payment of certain secured obligations in the manner provided for in the Security Agreement. The Amendment and Wavier does not substitute, replace or release the Pledgors from any other obligations under the RIPA or Security Agreement.

On November 23, 2022, the Company entered into Waiver and Amendment No. 3 to Revenue Interest Purchase Agreement and Amendment No. 2 to Security Agreement (the “RIPA Amendment 3”), by and among the Company, the Purchasers and the Purchaser Agent, which amends (i) the Revenue Interest Purchase Agreement, by and among the Company, the Purchasers, and the Purchaser Agent, dated effective as of June 26, 2019 (as amended by Amendment No. 1 to Revenue Interest Purchase Agreement dated as of November 9, 2020 and Amendment No. 2 to Revenue Interest Purchase Agreement dated as of April 26, 2021, and as may be further amended, restated, supplemented or modified from time to time, the “RIPA”) and (ii) the Security

10. Liability Related to the Revenue Interest Purchase Agreement (Continued)

Agreement, by the Company in favor of the Purchaser Agent, dated as of June 28, 2019 (as amended by the Amendment to Security Agreement and Waiver by and among the Company, the Purchaser and the Purchaser Agent, effective as of May 16, 2021, and as may be further amended, restated, supplemented or modified from time to time, the “Security Agreement”). Pursuant to the RIPA Amendment 3, among other things, (a) the Company agreed to make a one-time partial call payment with regards to the Revenue Interests (as defined in the RIPA) in an amount equal to $50 million from the restricted cash account (the “Partial Call”), (b) the amount of the Cumulative Purchaser Payments (as defined in the RIPA) was reduced to $177,777,778, and (c) the Purchasers and Purchaser Agent waived certain claimed defaults, breaches and Put Option Events under the RIPA and other related documents that may have occurred as a result of the Company’s opening of a new bank account.

In accordance with the guidance in ASC 470‐50, “Debt—Modifications and Extinguishments,” the RIPA Amendment 3 was accounted for as a debt modification. The amendment resulted in a less than $0.1 million loss on modification of debt, consisting of third-party fees associated with the transaction, which is included in selling, general, and administrative expenses in the statements of operations for the year ended December 31, 2022.

In connection with the arrangement, as of December 31, 2023, the Company has recorded a liability, referred to as the “Revenue interest liability” on the balance sheet, of $274.8 million, net of $0.2 million of capitalized issuance costs in connection with the RIPA, which will be amortized to interest expense over the estimated term of the RIPA. The total redemption amount is equal to 225% of the Cumulative Purchaser Payments, or $400 million. At December 31, 2023, the remaining redemption amount is $372.6 million. The Company imputes interest expense associated with this liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. The interest rate on this liability may vary during the term of the agreement depending on a number of factors, including the level of forecasted net sales. The Company evaluates the interest rate quarterly based on its current net sales forecasts utilizing the prospective method.

A significant increase or decrease in future net sales will materially impact the revenue interest liability, interest expense and the time period for repayment. The Company recorded approximately $46.7 million and $44.6 million in interest expense related to this arrangement for the years ended December 31, 2023 and 2022, respectively.

The repayment of the RIPA to Oberland does not have a fixed repayment schedule, rather it will be completely repaid and extinguished when the Company has repaid 225% of the Cumulative Purchaser Payments. Since there is not a fixed repayment schedule, the Company does not project its future repayments by year. Each period, the Company estimates the future expected sales of its products in the covered territory and determines the effective annual imputed interest rate, which updates and changes the timing of the Company’s payments. Under the terms of the agreement, every $100 million of net sales generated, less than or equal to $250 million in an annual aggregate year, would result in a repayment obligation of approximately $10.0 million or 10.0% at the stated repayment rate in the first year. Annual net sales for a calendar year exceeding $250 million would result in a repayment obligation of approximately $3.3 million or 3.3% for every $100 million of sales above the threshold. In 2025, the percent of net revenue paid to Oberland could reset to a higher amount if certain revenue milestones are not met. This could result in substantially higher payments starting in 2025. As the U.S. net sales were less than $350 million for the year ended December 31, 2021, the Covered Territory was expanded to include worldwide sales beginning in 2022. The Company’s repayments of the RIPA are directly tied to the growth of its net sales, and as the Company’s net sales grow, the Company expects the related repayments of the RIPA to grow as well. The Company currently expects to repay $34.8 million in the next twelve months.

The effective annual imputed interest rate is 17.6% as of December 31, 2023. Payments made to Oberland as a result of the Company’s net sales will reduce the revenue interest liability.
