Summary of Material Risks Associated with Our Business

Our business is subject to numerous risks and uncertainties that you should be aware of before making an investment decision, including those highlighted in the section entitled “Risk Factors.” These risks include, but are not limited to, the following:

•We depend almost entirely on the success of two products, bempedoic acid tablet and the bempedoic acid / ezetimibe combination tablet. There is no assurance that our continued commercialization efforts in the U.S. with respect to either product will be successful or that we will be able to generate revenues at the levels or within the timing we expect or at the levels or within the timing necessary to support our corporate goals.

•We have limited operating history as a commercial company and limited experience in the marketing and sale of NEXLETOL® (bempedoic acid) tablet and NEXLIZET® (bempedoic acid and ezetimibe) tablet in the U.S.

•Our relationships with customers and third-party payors are subject to applicable anti-kickback, fraud and abuse, and other healthcare laws and regulations, and health information privacy and security laws, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, and diminished profits and future earnings.

•Failure to obtain or maintain adequate coverage and reimbursement for new or current products could limit our ability to market those products and decrease our ability to generate revenue.

•Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our drug candidates and may decrease the prices we may obtain for our approved drugs.

•The commercial success of our approved drugs, and of any future approved drugs, will depend upon, among other things, the degree of market acceptance by physicians, patients, third-party payers, and others in the medical community.

•We have obtained regulatory approval from the U.S. Food and Drug Administration, or FDA, the European Medicines Agency, or EMA (which, with respect to the United Kingdom, converted to a Great Britain marketing authorization on January 1, 2021), and the Swiss Agency for Therapeutic Products, or Swissmedic, for both of our leading products as an adjunct to diet and statin therapy 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 low density lipoprotein cholesterol, or LDL-C. Daiichi Sankyo Co. Ltd, or DS, received its first regional approval for Hong Kong and launched in late 2023 and we expect additional approvals in the DS Territory in 2024. We have also 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 and we have also submitted 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 asking EMA to approve both NILEMDO and NUSTENDI to reduce cardiovascular risk in patients with or at high risk for atherosclerotic cardiovascular disease. We cannot be certain that we will be able to obtain approval for these expanded indications from FDA or European Commission, or EC, or from regulatory authorities in other territories we or our ex-U.S. commercial partners decide to pursue, or successfully commercialize our products and any future product candidates. Additionally, we cannot be certain that we will be able to obtain approval of either of our products for any other indication or approval of any future product candidates.

•While we successfully completed our CLEAR cardiovascular outcomes trial, or CVOT, for bempedoic acid and the trial met its primary endpoint, regulatory authorities may not approve any expanded indications for our products in the U.S. or other territories, and as a result, we may not receive significant milestone payments from our ex-U.S. commercial partners which could delay, prevent or limit our ability to generate revenue and continue our business.

•Our approved drugs and any drug candidates for which we obtain marketing approval will be subject to ongoing enforcement of post-marketing requirements and we could be subject to substantial penalties, including withdrawal of our approved drugs or any future approved products from the market, if we fail to comply with all regulatory requirements or if we experience unanticipated problems with our approved drugs or any future approved products, when and if any of them are approved.

•We may need substantial additional capital in the future. If additional capital is not available, we will have to delay, reduce or cease operations.

Table of Contents

•We may never achieve or maintain profitability.

•Manufacturing pharmaceutical products is complex and subject to product loss for a variety of reasons. We contract with third parties for the manufacture of bempedoic acid tablet and the bempedoic acid / ezetimibe combination tablet for commercialization and clinical trials. This reliance on third parties increases the risk that we will not have sufficient quantities of our drugs or drug candidates or such quantities at an acceptable cost or quality, which could delay, prevent, or impair our development or commercialization efforts.

•If we are unable to adequately protect our proprietary technology or maintain issued patents which are sufficient to protect bempedoic acid and the bempedoic acid / ezetimibe combination tablet, others could compete against us more directly, which would have a material adverse impact on our business, results of operations, financial condition and prospects.

•If we are not able to adequately prevent disclosure of trade secrets and other proprietary information, the value of our technology and products could be significantly diminished.

•Servicing our debt may require a significant amount of cash. If such cash is not available, we will have to delay, reduce or cease operations.

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

The summary risk factors described above should be read together with the text of the full risk factors below, in the section entitled “Risk Factors” and the other information set forth in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes, as well as in other documents that we file with the Securities and Exchange Commission, or the SEC. The risks summarized above or described in full below are not the only risks that we face. Additional risks and uncertainties not precisely known to us, or that we currently deem to be immaterial may also materially adversely affect our business, financial condition, results of operations and future growth prospects.

Item 1. Business

Overview

Esperion 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, 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 (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.

We completed a global cardiovascular outcomes trial, or CVOT, —known as Cholesterol Lowering via BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes. The trial was designed to evaluate whether treatment with bempedoic acid reduced the risk of cardiovascular events in adult patients who are statin averse and who have CVD or are at high risk for CVD. We initiated the CLEAR Outcomes CVOT in December 2016 and fully enrolled the study with nearly 14,000 patients in August 2019. The primary endpoint of the study was the effect of bempedoic acid on four types of major adverse cardiovascular events, or MACE (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization; also referred to as "four-component MACE"). CLEAR Outcomes was an event-driven trial and concluded once the predetermined number of MACE endpoints occurred. 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.

Our Strategy

We are focused on discovering, developing, and commercializing innovative medicines to help improve outcomes for patients. Our strategy for accomplishing this includes the following:

•Completion of global, landmark CLEAR Outcomes trial involving nearly 14,000 patients in 32 countries generated robust data, driving global awareness of significant cardiovascular risk reduction benefits of bempedoic acid. Dissemination of additional, powerful sub-group analyses at medical conferences and in top tier journals further serves to educate the market and support commercialization efforts.

Table of Contents

•Obtain significant label expansions for our existing products in the United States and Europe, which we anticipate will remove existing limitations and enable access to our life-saving therapies by millions more patients around the globe. We filed broad cardiovascular risk reduction labels in both jurisdictions and anticipate approvals in the first half of 2024.

•Execution of our strategic commercialization plan in order to generate significant growth for our currently approved products. We expect our anticipated label expansions and promotional efforts to unlock significant growth potential for NEXLETOL and NEXLIZET in the United States, with additional, commensurate growth potential in Europe driven by our partner’s efforts in that territory.

•Continue to advance our preclinical pipeline. We are leveraging our existing research and development capabilities to advance and grow our internal preclinical pipeline candidates, including next-generation ACLY inhibitors, which have potential for broad therapeutic application.

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 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.

Mechanism of Action

In November 2016, we announced the publication of “Liver-specific ATP Citrate Lyase inhibition by bempedoic acid decreases LDL-C and attenuates atherosclerosis,” by Pinkosky et al., in Nature Communications. The paper outlines the experiments and analyses undertaken by us and our collaborators to understand the mechanism of action for how bempedoic acid reduces LDL-C, including its specificity for the liver. Bempedoic acid is an adenosine triphosphate-citrate lyase, or ACL, inhibitor that lowers LDL-C by inhibition of cholesterol synthesis in the liver. ACL is an enzyme upstream of 3-hydroxy-3-methyl-glutaryl-coenzyme A, or HMG-CoA, reductase in the cholesterol biosynthesis pathway. Bempedoic acid and its active metabolite, ESP15228, require coenzyme A, or CoA, activation by very long-chain acyl-CoA synthetase 1, or ACSVL1, to ETC-1002-CoA and ESP15228-CoA, respectively. ACSVL1 is expressed primarily in the liver. Inhibition of ACL by ETC-1002-CoA results in decreased cholesterol synthesis in the liver and lowers LDL-C in blood via upregulation of low-density lipoprotein receptors.

Global Cardiovascular Outcomes Trial—CLEAR Outcomes

CLEAR Outcomes was a Phase 3 clinical study designed to evaluate if treatment with bempedoic acid reduces the risk of cardiovascular events in patients with statin intolerance who have cardiovascular disease or are at high risk for cardiovascular disease. We initiated CLEAR Outcomes in December 2016 and completed enrollment in August 2019. The primary endpoint of the study was the effect of bempedoic acid on major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization; also referred to as "four-component MACE").

The study included nearly 14,000 patients from over 1,200 sites in 32 countries. Eligible patients at high risk (LDL-C >100 mg/dL in primary prevention) for cardiovascular disease or with cardiovascular disease (LDL-C between 100 mg/dL to 190 mg/dL in secondary prevention) and who are only able to tolerate less than the lowest approved daily starting dose of a statin and considered statin adverse, were randomized to receive bempedoic acid 180 mg once-daily by mouth or matching placebo. The median duration of follow-up was 3.4 years. The average LDL-C level at the start of the study was 139 mg/dL.

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 at the Scientific Sessions of the American College of Cardiology with a simultaneous publication in the New England Journal of Medicine. The study showed that bempedoic acid demonstrated a significant 13% cardiovascular risk reduction in MACE-4 events and significantly reduced the risk of heart attack by 23% and coronary revascularization by 19% 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 bempedoic acid 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. When comparing these results in the context of other similar statin trials (based on the Cholesterol Treatment Trialists’, “CTT”, meta-analysis), when normalized to a 1.0 mmol/L (39 mg/dL) LDL-C reduction, the CV risk reduction with bempedoic acid shown via the CTT major vascular event endpoint is comparable to the normalized risk reduction observed with statins. The beneficial effect of bempedoic acid on major vascular event reduction generally improved over time, similar to what was observed in statin CVOTs.

On June 23, 2023, a prespecified analysis of the primary prevention population of the CLEAR Outcomes trial was presented at the American Diabetes Association Scientific Sessions and simultaneously published in the JAMA (Journal of the American Medical Association). Results from this primary prevention analysis show a significant 30% reduction in cardiovascular risk in the primary prevention population making bempedoic acid the first LDL-lowering therapy since statins to demonstrate cardiovascular risk reduction in a primary prevention population.

On August 26, 2023, a prespecified analysis of the total number of cardiovascular events in the CLEAR Outcomes trial population was presented at the European Society of Cardiology and subsequently published in JAMA Cardiology. The results reflect the totality of the benefit of bempedoic acid on CV risk reduction, not just the first event. Treatment with bempedoic acid was associated with a risk reduction of 20% in total MACE-4 events (composite of major adverse cardiovascular events including non-fatal myocardial infarction, non-fatal stroke, coronary revascularization and cardiovascular death), 17% in total MACE-3 events (composite of major adverse cardiovascular events including non-fatal myocardial infarction, non-fatal stroke and cardiovascular death), 31% in total myocardial infarctions, and 22% in total coronary revascularizations. We believe these data reinforce the importance of cholesterol lowering in high-risk patients with the potential to prevent multiple events over time.

On August 26, 2023, a prespecified analysis of the CLEAR Outcomes trial population by patient diabetes status at enrollment (e.g., diabetes, prediabetes, normoglycemic) was presented at the European Society of Cardiology and subsequently published in The Lancet Diabetes and Endocrinology. Of the nearly 14,000 patients included in CLEAR Outcomes, 45.6% had diabetes, 41.5% were pre-diabetic, and 12.9% had normoglycemia. Bempedoic acid demonstrated a benefit in patients with diabetes at baseline, showing a 17% reduction in cardiovascular risk. Importantly, bempedoic acid use was not associated with an increased rate of new onset diabetes, which is a key differentiating feature compared to statins.

Next Generation ACLYi

ATP-citrate lyase, or ACLY, is an enzyme strategically positioned at the intersection of nutrient catabolism and cholesterol and fatty acid biosynthesis. We are leading the investigation of ACLY biology, having brought the first ACLY inhibitor to the market. While preclinical studies and Mendelian randomized trials support a causal role for ACLY in dyslipidemia and

ASCVD, they also suggest potential additional effects on metabolism that may benefit other disease states such as type 2 diabetes and metabolic associated fatty liver disease (NAFLD)/metabolic associated steatohepatitis (NASH)1,2. Furthermore, emerging evidence implicates ACLY as a key metabolic checkpoint utilized by multiple cell types to sense nutrient availability and coordinate metabolic adaptions with cell-specific functions3,4. This expanded understanding has provided key insight into novel connections between chronic positive energy balance and aberrant metabolism and the maladaptation of multiple inflammatory, immune, fibrotic, extra-cellular matrix remodeling, and proliferative processes5-8. Our scientific team is exploring this novel insight into ACLY biology. Along with the implementation of leading-edge discovery technology and data science approaches, we aim to reveal new therapeutic opportunities and develop next-generation inhibitors optimized to address multiple life-threatening diseases.

Cardiovascular Disease and Elevated LDL-C

Atherosclerotic cardiovascular disease, or ASCVD, is a chronic, progressive disease; the presence of increasing low-density lipoprotein cholesterol, or LDL-C, is causal in the development of ASCVD and plays a central role in the multifactorial disease process of lipid accumulation and systemic inflammation. ASCVD is the underlying cause of many major cardiovascular, or CV, events including myocardial infarction, or MI, and ischemic stroke, or IS. In practice, ASCVD can include a spectrum of diagnoses, including acute events such as MI or stroke, coronary revascularization procedures, as well as conditions such as peripheral artery disease, or PAD, coronary artery disease, or CAD, or angina.

Extensive evidence has shown that LDL-C is a major risk factor for ASCVD. Studies further suggests that the causal effect of LDL-C on the risk of ASCVD is determined by both the degree and length of time LDL is elevated. The relationship between LDL-C levels and ASCVD risk has important implications, including:

• Lower LDL-C level attained using therapies that target LDL receptors yield greater clinical benefit in CV risk reduction than therapies that do not;

• There is a straight-line relationship between absolute reductions in LDL-C and reductions in the incidence of major vascular events (e.g., lower LDL-C is related to proportionally lower event rates);

• Cumulative LDL-C burden is a determinant of when ASCVD starts and/or gets worse; and

• Lowering LDL-C levels in patients with high CV risk earlier (rather than later) is recommended, especially for patients with familial hypercholesterolemia (FH).

Blood Cholesterol Guidelines

LDL-C is the main focus of healthcare provider efforts to improve the cholesterol profile in individuals at risk for or with established ASCVD, and the evidence overwhelmingly shows that the amount the risk of a poor outcome is lowered is related to the magnitude of LDL-C reduction, and that lowering LDL-C levels earlier (rather than later) is recommended, especially for patients with FH. Over the past 20 years since the inception of lipid targets in the NCEP ATP III (National Cholesterol Education Program Adult Treatment Panel III), guidelines have evolved to include lower LDL-C treatment targets in patients with established ASCVD.

The goal of treatment with intensive lipid-lowering strategies is to prevent subsequent CV events in patients with established ASCVD (secondary prevention) as well as to prevent the first CV event from occurring in patients who may be at high-risk for ASCVD (primary prevention).

Marketing Opportunity for Bempedoic Acid and the Bempedoic Acid / Ezetimibe Combination Tablet

Overall, 71 million adults in the US are at high risk of ASCVD and eligible for statin therapy according to the AHA/ACC guidelines.The estimated US prevalence of risk groups based on NHANES is provided below.

Table of Contents

US Prevalence Estimates by Statin-Eligible Groups

Patient Subgroup Estimated Prevalence (in Millions)

ASCVD and age ≥21 years 24.6

Diabetes mellitus (DM), age 40–75 years 15

Intermediate ASCVD (≥7.5% to <20%) risk and ≥1 risk enhancer(s) 20

Patients with HeFH or established ASCVD who require additional lowering of LDL-C

We initially developed bempedoic acid and the bempedoic acid / ezetimibe combination tablet as an adjunct to diet and statin therapy for patients with HeFH or ASCVD who require additional lowering of LDL-C. We further developed bempedoic acid as a treatment to reduce cardiovascular risk for patients with HeFH and ASCVD. The severity of elevated LDL-C in these patients, their level of cardiovascular disease risk and their therapeutic options vary widely.

Despite the prevalence of statins, many patients with ASCVD are still not achieving their LDL-C goals and need additional LDL-C lowering beyond that achieved with statin monotherapy. It is estimated that approximately 10 million patients with ASCVD in the United States currently taking statins require additional LDL-C lowering. Approximately 60% to 70% of patients receiving statins do not meet their LDL-C goals, and estimates are worse among high CV risk groups, such as adults with severe hypercholesterolemia (98%) or ASCVD (80%). There are also potentially 2 million additional patients with ASCVD not being treated per current guidelines because they cannot or will not take a high enough dose of a statin.

Patients at High Risk of Developing ASCVD (Primary Prevention)

Difficulty in achieving guideline recommended LDL-C goals is not limited to the established ASCVD population. Several recent estimates indicate that there may be up to 15 million US adults currently on statin medications for primary prevention who are not at goal and need treatment optimization, either via statin intensification or additional therapies. An additional 3 million adults who are eligible for statins for primary prevention may be statin intolerant, and unwilling or unable to initiate, continue, or maximize statin medications.

Untreated Patients

Due to a myriad of reasons, up to an additional 40 million adults in the US with ASCVD or at high-risk for ASCVD remain untreated with statins. This gap in care represents an important public health opportunity.

Unable or Unwilling to Take Guideline Recommended Doses of Statins

Muscle pain and weakness are the most common side effects experienced by statin users and the most common causes for discontinuing therapy. Moreover, a significant proportion of patients remain on statin therapy despite experiencing muscle-related side effects and require additional LDL-C lowering therapies to help them achieve their LDL-C treatment goals. Accordingly, we believe that in the presence of an oral, once-daily, non-statin LDL-C and cardiovascular risk lowering therapy, the statin intolerant market could grow substantially. According to our research, approximately 9.6 million patients in the United States are not on statins, need additional LDL-C lowering, and it is estimated that many are only able to tolerate less than the lowest approved daily starting dose of their statin and are therefore considered to be statin intolerant.

Other Approved LDL-C Lowering Therapies

Statin Therapy

Statins are the standard of care for patients with hypercholesterolemia today and are highly effective at lowering LDL-C. This class of drugs includes atorvastatin calcium, marketed as Lipitor®, the most prescribed LDL-C lowering drug in the world.

Statins are selective, competitive inhibitors of HMG-CoA reductase, a rate-limiting enzyme in the cholesterol biosynthesis pathway in liver cells. Statin inhibition of cholesterol synthesis increases the number of LDL receptors on the surface of liver cells. This increase in LDL receptors increases uptake of LDL particles into liver cells from the blood, thus lowering LDL-C

Table of Contents

levels. Statins are also thought to have a potential effect on cholesterol synthesis in skeletal muscle. This effect could be linked to the myalgia associated with statin use as seen in certain patients with statin intolerance.

The benefits of statin use in lowering LDL-C levels and improving cardiovascular outcomes are well documented. Despite the effectiveness of statins and their broad market acceptance, there are over 18 million diagnosed U.S. patients on maximally tolerated statin therapy (approximately 9 million patients who are currently taking a statin and over 9 million patients who cannot or will not take statins and for whom their maximally tolerated statin is no statin at all) who are unable to reach their LDL-C goal on their maximally tolerated statin therapy alone. In rare but extreme cases, statins can lead to muscle breakdown, kidney failure and death. For these reasons, we believe there is a continued unmet need for oral, once-daily, non-statin medicines to treat patients with elevated LDL-C.

Ezetimibe

Ezetimibe is a cholesterol absorption inhibitor that directly binds to NPC1L1 and prevents the transportation of dietary cholesterol from the gut lumen to intestinal enterocytes, resulting in decreased amounts of cholesterol delivered to the liver and an upregulation of hepatic LDL receptors. Ezetimibe also inhibits cholesterol absorption in the small intestine. Ezetimibe is indicated for monotherapy as an adjunctive therapy to diet for the reduction of elevated TC, LDL-C, Apo B, and non–HDL-C in patients with primary hyperlipidemia (HeFH and nonfamilial). It is also approved for combination therapy with a statin or fenofibrate. The standard dose of 10 mg/day lowers LDL-C by approximately 15% to 20% when used alone, in addition to the reduction achieved with statins. However, based on a retrospective real-world database study, it has been estimated that (depending on baseline LDL-C level) 70% or more of patients who switch to or add ezetimibe to statin therapy still require additional LDL-C lowering to achieve treatment goals (with therapeutic targets reached by only 30% of patients with baseline LDL-C levels of 70 to 99 mg/dL).

In November 2014, the results of the IMPROVE-IT (IMProved Reduction of Outcomes: Vytorin Efficacy International Trial) study were presented at the Scientific Sessions of the AHA. 18,144 patients with acute coronary syndrome were enrolled in IMPROVE-IT and were randomized to receive either 40 mg of simvastatin or 10 mg of ezetimibe/40 mg of simvastatin and were followed until > 5,250 events (cardiovascular death, heart attack, documented unstable angina requiring hospitalization, coronary revascularization, or stroke) occurred. The addition of ezetimibe to simvastatin resulted in a 6.4% relative risk reduction (p=0.016) in the aggregate of the events described above. This was the first study to demonstrate incremental clinical benefit with a non-statin when added to a statin.

Ezetimibe has been found to be generally well tolerated, and the ACC ECDP recommends that ezetimibe be considered the first non-statin agent added when LDL-C goal is not met with high-intensity statin therapy and diet and lifestyle modifications. However, the use of ezetimibe is markedly low in the US; in the GOULD registry (Getting to an Improved Understanding of Low-Density Lipoprotein Cholesterol and Dyslipidemia Management; 2016-2018) of adults with ASCVD, only 6.8% of patients with LDL-C ≥100 mg/dL had ezetimibe added for LLT intensification. Similar data from NHANES (2015-2018) showed that only 5.1% and 1.9% of high-risk and very high-risk ASCVD patients were receiving a statin plus ezetimibe, despite 61% and 74% of these patients having LDL-C ≥70 mg/dL.

PCSK9 Inhibitors, Monoclonal Antibodies

PCSK9 inhibitors block an enzyme involved in the degradation of LDL receptors. PCSK9 inhibitors are injectable, monoclonal antibodies to lower LDL-C. As described in currently approved U.S. prescribing information, PCSK9 inhibitors have demonstrated reductions of LDL-C when added on to maximally tolerated statin therapy in patients with HeFH and/or ASCVD of up to 64%. When PCSK9 inhibitors were used in patients with hypercholesterolemia considered to be statin intolerant, LDL-C levels were reduced by 45-56%. In 2015, the FDA approved two PCSK9 inhibitors: alirocumab, which was developed by Sanofi and Regeneron Pharmaceuticals, and evolocumab, which was developed by Amgen, Inc. These therapies were originally approved as an adjunct to diet and maximally tolerated statin therapy for patients with HeFH and/or ASCVD that require additional lowering of LDL-C. Additionally, evolocumab was approved as an adjunct to diet and other LDL-C lowering therapies for patients with HoFH. In 2016, Pfizer discontinued development of its PCSK9 inhibitor, bococizumab, due to unanticipated attenuation of LDL-C lowering over time in its Phase 3 studies.

In February 2017, Amgen announced top-line results for the FOURIER (Further Cardiovascular OUtcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk) CVOT where evolocumab demonstrated a statistically significant 15% reduction in the risk of cardiovascular events. Full results of FOURIER were presented at the Scientific Sessions of the American College of Cardiology in March 2017 and were published in the New England Journal of Medicine in March 2017. The FOURIER study enrolled 27,564 patients with prior ASCVD and LDL-C levels >70 mg/dl receiving background statin therapy. Patients were then blindly randomized to receive evolocumab or placebo and followed until at least 1630 key

Table of Contents

secondary endpoints (cardiovascular death, myocardial infarction, or stroke) occurred. In a patient population with a median baseline LDL-C level of 92 mg/dl, evolocumab reduced LDL-C by 59% as compared to placebo resulting in a 56 mg/dl absolute difference. This reduction in LDL-C translated to a 15% reduction in the primary endpoint (cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization). In December 2017, based upon the results of the FOURIER study, the indications for the use of evolocumab were updated to include reduction in risk of myocardial infarction, stroke, and coronary revascularization in adults with established cardiovascular disease, and for use alone or in combination with other lipid-lowering therapies to reduce LDL-C in adults with primary hyperlipidemia.

In March 2018, Regeneron Pharmaceuticals and Sanofi announced top-line results for the ODYSSEY Outcomes CVOT where alirocumab demonstrated a statistically significant 15% reduction in the risk of cardiovascular events. Full results of ODYSSEY Outcomes were presented at the Scientific Sessions of the ACC in March 2018 and were published in the New England Journal of Medicine in November 2018. The ODYSSEY Outcomes study enrolled 18,924 patients who had an acute coronary syndrome 1 to 12 months prior to study entry and LDL-C levels >70 mg/dl on high-intensity statin treatment. Patients were blindly randomized to receive alirocumab or placebo and followed until at least 1,613 patients experienced a primary endpoint of death from coronary heart disease, nonfatal myocardial infarction, fatal or nonfatal ischemic stroke or unstable angina requiring hospitalization. From a mean baseline of 92 mg/dl, LDL-C levels were reduced by 62.7% as compared to placebo, to a mean of 38 mg/dl. This treatment resulted in a 15% relative risk reduction in the primary MACE endpoint. In April 2019, the FDA approved alirocumab to reduce the risk of heart attack, stroke, and unstable angina requiring hospitalization in adults with established cardiovascular disease. On December 10, 2019, Regeneron Pharmaceuticals and Sanofi announced their intent to simplify their antibody collaboration for alirocumab by restructuring into a royalty-based agreement. Under the restructuring, which was effective April 2020, Regeneron has sole U.S. rights to alirocumab, and Sanofi has sole ex-U.S. rights to alirocumab.

In addition, evolocumab and alirocumab are indicated for use alone or in combination with other lipid-lowering agents for patients with primary hyperlipidemia, including familial and nonfamilial hypercholesterolemia. Notwithstanding the LDL-C lowering efficacy of PCSK9 inhibitors, we believe their adoption by patients, physicians, and payors could be adversely impacted by their higher cost, notwithstanding recent price reductions, substantial prior authorization processes, and their injectable route of administration.

PCSK9 inhibitors, small interfering ribonucleic acid (siRNA)

Novartis AG developed inclisiran and the new drug application, or NDA, for inclisiran was submitted to the FDA in December 2019. Inclisiran (which is marketed in the U.S. as Leqvio®) received FDA approval on December 22, 2021. Unlike the PCSK9 antibodies from Regeneron Pharmaceuticals and Sanofi and Amgen, inclisiran is a long-acting RNA interference therapeutic agent that inhibits the synthesis of PCSK9. Findings from clinical studies suggest that inclisiran may be dosed every 6 months, with a 3-month timeframe only between the first and second dose. Like the PCSK9 antibodies, inclisiran is an injectable therapy that lowers LDL-C between 45% to 58% in Phase 3 clinical testing. In November 2019, Novartis AG acquired The Medicines Company. The Medicines Company initiated the ORION-4 trial in October 2018 which is designed to evaluate cardiovascular outcomes in 15,000 people being treated with inclisiran or placebo. Recruitment of ORION-4 was completed September 30, 2023. Inclisiran received an updated indication in July 2023 for use as an adjunct to diet and statin therapy for the treatment of adults with primary hyperlipidemia, including HeFH, to reduce LDL-C.

Revenue

We derive revenue through two primary sources: product sales and collaboration revenue. Product sales is related to our sales of NEXLETOL and NEXLIZET in the U.S. 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 consists of the collaboration payments made to us under our collaboration arrangements outside of the U.S. for the development and commercialization of our product candidates by our partners. Collaboration revenue also includes royalty revenue and sales of bulk tablets of our products to our collaboration partners.

During the year ended December 31, 2023, we recognized $78.3 million in net product sales of NEXLETOL and NEXLIZET and $38.0 million in collaboration revenue, primarily related to sales of bulk tablets under supply agreements and royalty revenue received from collaboration partners. During the year ended December 31, 2022, we recognized $55.9 million in net product sales of NEXLETOL and NEXLIZET and $19.6 million in collaboration revenue, primarily related to sales of bulk tablets under supply agreements and royalty revenue received from collaboration partners.

Table of Contents

If we fail to complete the development of bempedoic acid or the bempedoic acid / ezetimibe combination tablet (including obtaining additional potential indications), or any other product candidates we may develop, and do not secure additional approvals from regulatory authorities in the U.S., Europe and other territories, our ability to generate future revenue and our results of operations and financial position may be adversely affected.

Research and Development Expenses

Research and development expenses for the year ended December 31, 2023, were $86.1 million, which was primarily related to clinical development costs relating to the CLEAR Outcomes CVOT and compensation related costs, including stock-based compensation.

Selling, General and Administrative

We established our commercialization and distribution capabilities with the commercial launch of NEXLETOL and NEXLIZET in the U.S. We announced collaboration agreements for the commercialization of bempedoic acid and the bempedoic acid / ezetimibe combination tablet with Daiichi Sankyo Europe GmbH, or DSE in 2019, with Otsuka Pharmaceutical Co., Ltd., or Otsuka, in 2020 and with Daiichi Sankyo Co. Ltd, or DS in 2021.

We continue to engage in partnering discussions with potential third-party collaborators. We intend to seek approval and launch commercial sales of the bempedoic acid and the bempedoic acid / ezetimibe combination tablet in unpartnered territories outside of the United States by establishing additional collaborations with one or more pharmaceutical company collaborators, depending on, among other things, the applicable indications, the related development costs and our available resources.

We expect our selling, general and administrative expenses to increase in 2024 in anticipation of potential additional global approvals for new product indications, expanded commercialization initiatives for NEXLETOL and NEXLIZET and increases in our associated headcount to expand our sales team. Selling, general and administrative expenses in 2023 increased primarily due to increased legal expenses associated with our litigation with DSE, including the close out costs associated with the settlement, and increases in headcount, consulting and other promotional related expenses.

Manufacturing and Supply

Bempedoic acid and the bempedoic acid / ezetimibe combination tablet are small molecule drugs that are synthesized from readily available raw materials using conventional chemical processes. We currently have no manufacturing facilities. We rely on contract manufacturers to produce both drug substances and drug products required for our commercial supply and clinical studies. All lots of drug substance and drug product used in commercial supply and clinical studies are manufactured under current good manufacturing practices. We plan to continue to rely upon contract manufacturers and, potentially, in connection with the transfer of certain manufacturing responsibilities to DSE, collaboration partners to manufacture commercial quantities of the bempedoic acid and the bempedoic acid / ezetimibe combination tablet in the United States and in Europe and in territories outside of the United States and Europe.

Licenses and Collaboration Agreements

In April 2008, we entered into an asset transfer agreement with Pfizer pursuant to which we acquired all intellectual property owned by Pfizer relating exclusively to the bempedoic acid program. We also entered into a license agreement providing a worldwide, exclusive, fully paid-up license of certain residual background intellectual property not transferred pursuant to the asset transfer agreement, and we granted Pfizer a worldwide, exclusive, fully paid-up license to certain patent rights owned or controlled by us relating to development programs other than bempedoic acid. The license to us covers the development, manufacturing and commercialization of bempedoic acid. There are no restrictions or limitations and we may grant sublicenses under the license agreements. Pfizer is not entitled to any royalties, milestones or any similar development or commercialization payments under the terms of the agreements, and the licenses granted are irrevocable and may not be terminated for any cause, including intentional breaches or breaches caused by gross negligence.

On January 2, 2019, we entered into a license and collaboration agreement, or LCA, with DSE. Pursuant to the agreement, we have granted DSE exclusive commercialization rights to bempedoic acid and the bempedoic acid / ezetimibe combination tablet in the European Economic Area and Switzerland, or the DSE Territory. DSE will be responsible for commercialization in the DSE Territory. We remain responsible for clinical development, regulatory and manufacturing activities for the licensed products globally, including in the DSE Territory. On June 18, 2020, we entered into an amendment to the LCA Amendment with DSE to include Turkey. DSE’s designated affiliate in Turkey will be solely responsible, at its sole cost and expense, for all regulatory matters relating to such products in Turkey, including obtaining Regulatory Approval for such products in Turkey. On January 3, 2024, we announced that after a transition period, DSE will assume sole responsibility for the manufacture of

Table of Contents

NILEMDO and NUSTENDI for the DSE Territory and that we granted 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.

On April 17, 2020, we entered into a license and collaboration agreement, or the Otsuka Agreement, with Otsuka Pharmaceutical Co., Ltd., or Otsuka. Pursuant to the Otsuka Agreement, we granted Otsuka exclusive development and commercialization rights to bempedoic acid and the bempedoic acid / ezetimibe combination tablet 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.

On December 3, 2020, we entered into a definitive agreement with Serometrix to in-license its oral, small molecule PCSK9 inhibitor program. Serometrix developed the oral PCSK9 inhibitor program with its proprietary technology to discover drugs for challenging protein targets. 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.

On April 26, 2021, we entered into a license and collaboration agreement with DS. Pursuant to the agreement, we granted DS exclusive development and commercialization rights to bempedoic acid and the bempedoic acid / ezetimibe combination tablet in South Korea, Taiwan, Hong Kong, Thailand, Vietnam, Brazil, Macao, Cambodia and Myanmar, or 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. On January 3, 2024, we announced that after a transition period, DS will assume sole responsibility for the manufacture of NILEMDO and NUSTENDI for the DS Territory and that we granted DS the exclusive rights for clinical development, regulatory activities, manufacture and commercialization of a bempedoic acid/ezetimibe/statin triple combination pill in the DS Territory.

For additional details on the DSE, Otsuka, Serometrix and DS agreements, see Note 3 to our audited financial statements appearing elsewhere in this Annual Report on Form 10-K.

Intellectual Property

We strive to protect and enhance the proprietary technologies that we believe are important to our business, including seeking and maintaining patents intended to cover our products and compositions, their methods of use and any other inventions that are important to our business. We also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection.

Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to our business, defend and enforce our patents, preserve the confidentiality of our trade secrets and operate without infringing the valid and enforceable patents and proprietary rights of third parties. We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen and maintain the proprietary position of bempedoic acid, the bempedoic acid / ezetimibe combination tablet and our other development programs.

As of December 31, 2023, our patent estate, including patents we own, on a worldwide basis, included approximately 10 issued United States patents and 17 pending United States patent applications and over 25 issued patents and over 80 pending patent applications in other foreign jurisdictions. Of our worldwide patent estate, only a subset of our patents and pending patent applications relates to our bempedoic acid program.

Bempedoic acid is claimed in U.S. Patent No. 7,335,799 that is scheduled to expire in December 2025, which includes 711 days of patent term adjustment, and may be eligible for a patent term extension period of up to five years. We have requested a five year patent term extension of U.S. Patent No. 7,335,799, and we believe that this patent could be the subject of an additional six month pediatric exclusivity period. We have one granted European patent that has been validated in numerous European countries including France, Germany, Great Britain, Ireland, Italy, the Netherlands, Spain, Sweden and Switzerland. We obtained five year patent term extensions via supplementary protection certificates for 24 national patents validated from this granted European patent, which extends our patent protection in those countries until 2028. Additionally, we have one patent family that includes U.S. Patent No. 11,407,705, directed to the method of manufacturing high purity bempedoic acid, one pending U.S. patent application directed to the same, U.S. Patent No. 11,613,511 directed to compositions of matter of high purity bempedoic acid, one pending U.S. patent application directed to the same, U.S. Patent No. 11,760,714 directed to pharmaceutical formulations containing the same, one pending U.S. patent application directed to methods of treatment using

Table of Contents

the same, and 15 pending patent applications outside of the United States. U.S. Patent Nos. 11,407,705, 11,613,511 and 11,760,714, and the other patent family members, if issued, are scheduled to expire in June 2040.

In addition, we have three patent families in which we are pursuing patent protection for our bempedoic acid and bempedoic acid / ezetimibe combination tablet in combination with one or more statins. Methods of treating familial hypercholesterolemia with the bempedoic acid / ezetimibe combination tablet are claimed in U.S. Patent Nos. 10,912,751 and 11,744,816 that are scheduled to expire in March 2036. We also have one pending U.S. patent application, and 9 issued patents and 14 pending applications outside the U.S. with claims directed to methods of treatment using the bempedoic acid / ezetimibe combination tablet. Additionally, we have one pending U.S. patent application, and 7 issued patents and 23 pending applications outside of the U.S. directed to the manufacturing of our bempedoic acid / ezetimibe combination tablet. We also have one issued U.S. patent, i.e., U.S. Patent No. 11,116,739, one pending U.S. patent application, and 9 issued patents and 15 pending applications outside the U.S., with claims directed to fixed dose combinations of bempedoic acid and one or more statins and/or methods of using said fixed dose combinations. U.S. Patent No. 11,116,739 is scheduled to expire in March 2036.

In addition to the patents we own, we also hold an exclusive, worldwide, fully paid-up license on any residual background intellectual property not transferred from Pfizer pursuant to our asset transfer agreement with Pfizer.

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the date of filing a non-provisional application. In the United States, a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the U.S. Patent and Trademark Office in granting a patent, or may be shortened if a patent is terminally disclaimed over an earlier-filed patent. In addition, in certain instances, a patent term can be extended to recapture a portion of the term effectively lost as a result of the FDA regulatory review period. However, the restoration period cannot be longer than five years and the total patent term including the restoration period must not exceed 14 years following FDA approval. We have submitted a request for a patent term extension in the United States for U.S. Patent No. 7,335,799. However, the applicable authorities, including the FDA and the U.S. Patent and Trademark Office, or USPTO, in the United States, and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. The duration of foreign patents varies in accordance with provisions of applicable local law, but typically is also twenty years from the earliest effective filing date. Our issued U.S. patents relating to bempedoic acid, including patent term extensions we may be eligible for, will expire on dates ranging from late-2025 to mid-2040. However, the actual protection afforded by a patent varies on a claim by claim basis for each applicable product, from country to country and depends upon many factors, including the type of patent, the scope of its coverage, the availability of regulatory related extensions, the availability of legal remedies in a particular country and the validity and enforceability of the patent.

Furthermore, the patent positions of biotechnology and pharmaceutical products and processes like those we intend to develop and commercialize are generally uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in such patents has emerged to date in the U.S. The patent situation outside the U.S. is even more uncertain. Changes in either the patent laws or in interpretations of patent laws in the U.S. and other countries can diminish our ability to protect our inventions, and enforce our intellectual property rights and more generally, could affect the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents.

The biotechnology and pharmaceutical industries are characterized by extensive litigation regarding patents and other intellectual property rights. Our ability to maintain and solidify our proprietary position for our drugs and technology will depend on our success in obtaining effective claims and enforcing those claims once granted. We do not know whether any of the patent applications that we may file or license from third parties will result in the issuance of any patents. The issued patents that we own or may receive in the future, may be challenged, invalidated or circumvented, and the rights granted under any issued patents may not provide us with proprietary protection or competitive advantages against competitors with similar technology. Furthermore, our competitors may be able to independently develop and commercialize similar drugs or duplicate our technology, business model or strategy without infringing our patents. Because of the extensive time required for clinical development and regulatory review of a drug we may develop, it is possible that, before any of our drugs can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of any such patent.

We may rely, in some circumstances, on trade secrets and unpatented know-how to protect our technology. However, trade secrets can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with our consultants, vendors, collaborators, scientific advisors, contractors and other third parties and invention assignment agreements with our employees. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information

Table of Contents

technology systems. While we have confidence in these individuals, organizations and systems, agreements or security measures may be breached and we may not have adequate remedies for any breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. To the extent that our consultants, vendors, collaborators, scientific advisors, contractors or other third parties use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions. For more information, please see “Risk Factors—Risks Related to our Intellectual Property.”

Our commercial success will also depend in part on not infringing the proprietary rights of third parties. It is uncertain whether the issuance of any third-party patent would require us to alter our development or commercial strategies, or our drugs or processes, obtain licenses or cease certain activities. Our breach of any license agreements or failure to obtain a license to proprietary rights that we may require to develop or commercialize bempedoic acid, the bempedoic acid / ezetimibe combination tablet, or any other product candidates may have a material adverse impact on us. If third parties prepare and file patent applications in the U.S. that also claim technology to which we have rights, we may have to participate in an interference or derivation proceeding at the USPTO, to determine who is entitled to claim invention.

In addition, substantial scientific and commercial research has been conducted for many years in the areas in which we have focused our development efforts, which has resulted in third parties having a number of issued patents and pending patent applications. Patent applications in the U.S. and elsewhere are published only after eighteen months from the priority date. The publication of discoveries in the scientific or patent literature frequently occurs substantially later than the date on which the

underlying discoveries were made. Therefore, patent applications relating to drugs similar to bempedoic acid and any future drugs, discoveries or technologies we might develop may have already been filed by others without our knowledge.

Competition

Our industry is highly competitive and subject to rapid and significant technological change. Our potential competitors include large pharmaceutical and biotechnology companies, specialty pharmaceutical and generic drug companies, academic institutions, government agencies and research institutions. Key competitive factors affecting the commercial success of our product candidates are likely to be efficacy, safety and tolerability profile, reliability, convenience of dosing, price and reimbursement.

The market for cholesterol regulating therapies is especially large and competitive. The product candidates we are currently developing and commercializing will face intense competition, either as monotherapies or as combination therapies.

Many of our existing or potential competitors have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of products and the commercialization of those products. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a small number of our competitors. Accordingly, our competitors may be more successful than we may be in obtaining FDA approval for drugs and achieving widespread market acceptance. Our competitors’ drugs may be more effective, or more effectively marketed and sold, than any drug we may commercialize and may render our product candidates obsolete or non-competitive before we can recover the expenses of developing and commercializing any of our product candidates. Our competitors may also obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours. We anticipate that we will face intense and increasing competition as new drugs enter the market and advanced technologies become available. Finally, the development of new treatment methods for the diseases we are targeting could render our drugs non-competitive or obsolete. See “Risk Factors—Risks Related to Sales, Marketing, and Competition—Our market is subject to intense competition. If we are unable to compete effectively, our opportunity to generate revenue from the sale of bempedoic acid or the bempedoic acid / ezetimibe combination tablet in the U.S., in Europe and in other territories will be materially adversely affected.”

Regulatory Matters

Government Regulation and Product Approval

Government authorities in the United States at the federal, state and local level, and in other countries, extensively regulate, among other things, the research, and clinical development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing, pricing, export and import of drug products such as those we are developing and have developed. Generally, before a new drug can be marketed, considerable data demonstrating its quality, safety, and efficacy must be obtained, organized into a format specific to each regulatory authority, submitted for review, and approved by the regulatory authority.

Table of Contents

Drugs are also subject to other federal, state, and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable regulatory requirements at any time during the product development process, approval process, or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the regulatory authority's refusal to approve pending applications, withdrawal of an approval, clinical holds, untitled or warning letters, voluntary product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution, injunctions, debarment, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

United States Drug Review and Approval

United States Drug Development Process

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or the FDCA, and its implementing regulations. The process of obtaining regulatory approvals and compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process, or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, voluntary product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. The process required by the FDA before a drug may be marketed in the United States generally involves the following:

•completion of extensive preclinical, sometimes referred to as nonclinical, laboratory tests, animal studies and formulation studies all performed in accordance with applicable regulations, including the FDA's good laboratory practice, or GLP, regulations;

•submission to the FDA of an Investigational New Drug application, or IND, which must become effective before human clinical trials may begin and must be updated annually;

•performance of adequate and well-controlled human clinical trials in accordance with the applicable IND and other clinical trial-related regulations, sometimes referred to as Good Clinical Practices, or GCP, to establish the safety and efficacy of the proposed drug for its proposed indication;

•submission to the FDA of an NDA for a new drug;

•a determination by the FDA within 60 days of its receipt of a NDA to file the NDA for review;

•satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the active pharmaceutical ingredient, or API, and finished drug product are produced to assess compliance with current good manufacturing practices, or cGMP;

•satisfactory completion of any FDA inspections of clinical trial sites, sponsor, and/or clinical research organizations to assess compliance with GCP and assure the integrity of clinical data in support of the NDA;

•potential FDA audit of the clinical trial sites that generated the data in support of the NDA;

•review and input from an advisory committee, if requested by FDA; and

•FDA review and approval of the NDA.

Once a pharmaceutical product candidate is identified for development, it enters the nonclinical, also referred to as preclinical, testing stage. Nonclinical tests include laboratory evaluations of product chemistry, toxicity, formulation and stability, as well as animal studies. A sponsor must submit the results of the nonclinical tests, together with manufacturing information, analytical data and any available clinical data or literature, to the FDA as part of the IND. The sponsor must also include a protocol detailing, among other things, the objectives of the initial clinical study, dosing procedures, subject selection and exclusion criteria, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the initial clinical study lends itself to an efficacy evaluation. Some nonclinical testing may continue even after the IND is submitted. The

Table of Contents

IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA places the clinical study on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical study can begin. Clinical holds also may be imposed by the FDA at any time before or during clinical studies due to safety concerns or non-compliance, and may be imposed on all drug products within a certain class of drugs. The FDA also can impose partial clinical holds, for example prohibiting the initiation of clinical studies of a certain duration or for a certain dose.

All clinical studies must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. These regulations include the requirement that all research subjects provide informed consent. Further, an institutional review board, or IRB, must review and approve the plan for any clinical study before it commences at any institution. An IRB considers, among other things, whether the risks to individuals participating in the clinical study are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the information regarding the clinical study and the consent form that must be provided to each clinical study subject or his or her legal representative and must monitor the clinical study until completed.

Each new clinical protocol and any amendments to the protocol must be submitted to the IND for FDA review, and to the IRBs for approval. There are also requirements governing the reporting of ongoing clinical trials and clinical trial results to public registries.

Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination on their www.clinicaltrials.gov website. Information related to the product, patient population, phase of investigation, study sites and investigators and other aspects of the clinical trial is made public as part of the registration of the clinical trial. Although sponsors are obligated to disclose the results of their clinical trials after completion, disclosure of the results can be delayed in some cases for up to two years after the date of completion of the trial. Failure to timely register a covered clinical study or to submit study results as provided for in the law can give rise to civil monetary penalties and also prevent the non-compliant party from receiving future grant funds from the federal government. The NIH’s Final Rule on ClinicalTrials.gov registration and reporting requirements became effective in 2017, and both the NIH and FDA have signaled the government’s willingness to begin enforcing those requirements against non-compliant clinical trial sponsors.

Human clinical studies are typically conducted in three sequential phases that may overlap or be combined:

•Phase 1. The product is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life- threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing may be conducted in patients.

•Phase 2. Involves clinical studies in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage and schedule.

•Phase 3. Clinical studies are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical study sites. These clinical studies are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product labeling.

Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events, including any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator’s brochure, or any findings from other studies or animal or in vitro testing that suggest a significant risk in humans exposed to the product candidate. Phase 1, Phase 2 and Phase 3 testing may not be completed successfully within any specified period, if at all. The FDA or the sponsor may suspend or terminate a clinical study at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical study at its institution if the clinical study is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients.

Concurrent with clinical studies, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested

Table of Contents

and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life.

NDA and FDA Review Process

The results of product development, nonclinical studies and clinical studies, along with descriptions of the manufacturing process, analytical tests conducted on the drug, proposed labeling and other relevant information, are submitted to the FDA as part of an NDA for a new drug, requesting approval to market the product. The submission of an NDA is subject to the payment of a substantial user fee; a waiver of such fee may be obtained under certain limited circumstances. For example, the agency will waive the application fee for the first human drug application that a small business or its affiliate submits for review. The Company obtained a Small Business Waiver from the FDA related to bempedoic acid. There is also an annual prescription drug program fee for each approved prescription drug product on the market.

In addition, under the Pediatric Research Equity Act of 2003, or PREA, as amended made into permanent law pursuant to Food and Drug Administration Safety and Innovation Act (FDASIA), an NDA or supplement to an NDA must contain data to assess the safety and effectiveness of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers.

The FDA reviews all NDAs submitted to ensure that they are sufficiently complete for substantive review before it accepts them for filing. The FDA may request additional information rather than accept an NDA for filing. In this event, the NDA must be re-submitted with the additional information. The re-submitted application also is subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA reviews an NDA to determine, among other things, whether a product is safe and effective for its intended use and whether its manufacturing is cGMP-compliant to assure and preserve the product’s identity, strength, quality and purity. Before approving an NDA, the FDA will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA also can require, or an NDA applicant may voluntarily propose, a Risk Evaluation and Mitigation Strategy, or REMS, to ensure the benefits of a drug outweigh its risks. Elements of a REMS may include “dear doctor letters,” a medication guide, and in some cases restrictions on distribution. These elements are negotiated as part of the NDA approval, and in some cases may delay the approval date. Once adopted, REMS are subject to periodic assessment and modification. The FDA may refer the NDA to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions. An advisory committee is a panel of experts who provide advice and recommendations when requested by the FDA on matters of importance that come before the agency. The FDA is not bound by the recommendation of an advisory committee.

The approval process is lengthy and difficult and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require additional clinical data or other data and information. Even if such data and information are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical studies are not always conclusive and the FDA may interpret data differently than we interpret the same data. The FDA will issue a complete response letter if the agency decides not to approve the NDA in its present form. The complete response letter usually describes all of the specific deficiencies that the FDA identified in the NDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical studies. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application or request an opportunity for a hearing.

Post-Marketing Requirements

Following approval of a new drug, a pharmaceutical company and the approved drug are subject to continuing regulation by the FDA, including, among other things, establishment registration and drug listing, monitoring and recordkeeping activities, reporting to the applicable regulatory authorities of adverse experiences with the drug, providing the regulatory authorities with updated safety and efficacy information, drug sampling and distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the drug's approved labeling (known as off-label promotion), and limitations on industry-sponsored scientific and educational activities. Although physicians may prescribe legally available drugs for off-label uses, the FDA takes the position that manufacturers may not market or promote such off-label uses. Modifications or enhancements to the drug or its labeling or changes of the site or process of manufacturing are often subject to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process.

Table of Contents

Prescription drug advertising is subject to federal, state, and foreign regulations. In the U.S., the FDA regulates prescription drug promotion, including direct-to-consumer advertising. Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Any distribution of prescription drugs and pharmaceutical samples must comply with the U.S. Prescription Drug Marketing Act, or the PDMA, a part of the FDCA. The Drug Supply Chain Security Act, or DSCSA, was enacted in 2013 with the aim of building an electronic system to identify and trace certain prescription drugs distributed in the U.S. The DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers, wholesale distributors, and dispensers over a 10-year period that culminated in November 2023. The FDA established a one-year stabilization period from November 2023 to November 2024 for trading partners to continue to build and validate interoperable systems and processes to meet certain requirements of the DSCSA. The law's requirements include the quarantine and prompt investigation of a suspect product to determine if it is illegitimate and notifying trading partners and the FDA of any illegitimate product. Drug manufacturers and their collaborators are also required to place a unique product identifier on prescription drug packages. This identifier consists of the National Drug Code, serial number, lot number, and expiration date, in the form of a 2-dimensional data matrix barcode that can be read by humans and machines.

In the U.S., once a drug is approved, its manufacturing is subject to comprehensive and continuing regulation by the FDA. FDA regulations require that drugs be manufactured in specific facilities per the NDA approval and in accordance with cGMP. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our approved drug and drug candidates in accordance with cGMP regulations. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Drug manufacturers and other entities involved in the manufacturing and distribution of approved drugs, and those supplying products, ingredients, and components of them, are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. These regulations also impose certain organizational, procedural, and documentation requirements with respect to manufacturing and quality assurance activities. NDA holders using contract manufacturers, laboratories, or packagers are responsible for the selection and monitoring of qualified firms, and, in certain circumstances, qualified suppliers to these firms. These firms and, where applicable, their suppliers are subject to inspections by the FDA at any time, and the discovery of violative conditions, including failure to conform to cGMP, could result in enforcement actions that interrupt the operation of any such facilities or the ability to distribute drugs manufactured, processed, or tested by them. Discovery of problems with a drug after approval may result in restrictions on a drug, manufacturer, or holder of an approved NDA, including, among other things, recall or withdrawal of the drug from the market, and may require substantial resources to correct.

The FDA also may require post-approval testing, sometimes referred to as Phase 4 testing, risk minimization action plans, and post-marketing surveillance to monitor the effects of an approved drug or place conditions on an approval that could restrict the distribution or use of the drug, such as the FDA has imposed and we have agreed to for NEXLETOL and NEXLIZET. Specifically, as part of our NEXLETOL and NEXLIZET approval, the FDA required both a pharmacokinetics / pharmacodynamics, or PK/PD, and Phase 3 study evaluating bempedoic acid in patients with HeFH aged 10 years to less than 18 years, a worldwide descriptive study that collects prospective and retrospective data in women exposed to NEXLETOL and NEXLIZET during pregnancy to assess the risk of pregnancy and maternal complications, adverse effects on the developing fetus and neonate, and adverse effects on the infant through the first year of life, a lactation study to analyze milk in lactating women who have received therapeutic doses of NEXLETOL and NEXLIZET, and that we complete the CLEAR Outcomes CVOT trial.

Discovery of previously unknown problems with a drug or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial, or administrative enforcement, untitled or warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a drug's approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures, including a REMS or the conduct of post-marketing studies to assess a newly discovered safety issue. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA's policies may change, which could delay or prevent regulatory approval of our drug candidates under development.

Other Regulatory Matters

Manufacturing, sales, promotion, and other activities following drug approval are also subject to regulation by numerous regulatory authorities in addition to the FDA, including, in the U.S., the Centers for Medicare & Medicaid Services, or CMS, other divisions of the U.S. Department of Health and Human Services, or HHS, the Drug Enforcement Administration for controlled substances, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, and state and local governments. In the U.S., sales, marketing, and scientific/educational programs must also comply with state and federal fraud and abuse laws. Pricing and rebate programs

Table of Contents

must comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the Patient Protection and Affordable Care Act as amended by the Health Care and Education Reconciliation Act of 2010 (or collectively, the ACA). If drugs are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. The handling of any controlled substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Drugs must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion, and other activities are also potentially subject to federal and state consumer protection and unfair competition laws.

We are subject to numerous foreign, federal, state, and local environmental, health, and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment, and disposal of hazardous materials and wastes. In addition, our leasing and operation of real property may subject us to liability pursuant to certain U.S. environmental laws and regulations, under which current or previous owners or operators of real property and entities that disposed or arranged for the disposal of hazardous substances may be held strictly, jointly, and severally liable for the cost of investigating or remediating contamination caused by hazardous substance releases, even if they did not know of and were not responsible for the releases.

The distribution of pharmaceutical drugs is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage, and security requirements intended to prevent the unauthorized sale of pharmaceutical drugs.

The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in criminal prosecution, fines, or other penalties, injunctions, voluntary recall or seizure of drugs, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to allow a firm to enter into supply contracts, including government contracts. In addition, even if a firm complies with FDA and other requirements, new information regarding the safety or efficacy of a product could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of our approved drug or any future products marketed by us could materially affect our business in an adverse way.

Changes in regulations, statutes, or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our product; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of FDA approval of the use of our product candidates, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time, diligently spent, between the effective date of an IND and the submission date of an NDA plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. We applied for restorations of patent term for some of our currently owned or licensed patents to add patent life beyond their current expiration dates, depending on the expected length of the clinical studies and other factors involved in the filing of the relevant NDA; however, there can be no assurance that any such extension will be granted to us.

Market exclusivity provisions under the FDCA can also delay the submission or the approval of certain applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application, or ANDA, or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions of use

Table of Contents

associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the nonclinical studies and adequate and well- controlled clinical studies necessary to demonstrate safety and effectiveness.

Pediatric exclusivity is another type of exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods for all formulations, dosage forms, and indications of the drug and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection and, for drugs, patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study, provided that at the time pediatric exclusivity is granted there is not less than nine months of term remaining.

Certain foreign countries permit extension of patent term for a newly approved drug and/or grant a period of data exclusivity and/or market exclusivity. For example, depending upon the timing and duration of the marketing authorization process in certain European countries, a newly approved drug may be eligible for a supplementary protection certification, or SPC, which can extend the basic patent right for the drug for a period up to five years.

Coverage, Reimbursement and Healthcare Reform

Sales of NEXLETOL and NEXLIZET and any future approved drugs will depend, in part, on the extent to which such drugs will be covered by third-party payors, such as government health programs, commercial insurers, and managed healthcare organizations, as well as the level of reimbursement such third-party payors provide for our products. Patients and providers are unlikely to use NEXLETOL and NEXLIZET or any future approved drugs unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of such drugs. These third-party payors are increasingly reducing reimbursements for medical drugs and services.

In the U.S., no uniform policy of coverage and reimbursement for drugs or biological products exists, and one payor's determination to provide coverage and adequate reimbursement for a product does not assure that other payors will make a similar determination. In the U.S., the principal decisions about reimbursement for new medicines are typically made by the CMS, an agency within the HHS, as the CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare. Private third-party payors tend to follow Medicare coverage and reimbursement limitations to a substantial degree, but also have their own methods and approval process apart from Medicare determinations. Accordingly, decisions regarding the extent of coverage and amount of reimbursement to be provided for NEXLETOL and NEXLIZET or any of our future drug candidates, if approved, are made on a payor-by-payor basis. Factors payors consider in determining reimbursement are based on whether the product is:

•a covered benefit under its health plan;

•safe, effective and medically necessary;

•appropriate for the specific patient;

•cost-effective; and

•neither experimental nor investigational.

As a result, the coverage determination process may be a time-consuming and costly process that will require us to provide scientific and clinical support for the use of NEXLETOL and NEXLIZET or any future approved drugs to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained. Even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain profitability or may require co-payments that patients find unacceptably high. Net prices for NEXLETOL and NEXLIZET or any future approved drugs may also be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products.

In the case of our Medicaid pricing data, if we become aware that our reporting for a prior quarter is incorrect, or has changed as a result of recalculation of the pricing data, we are obligated to resubmit the corrected data for up to three years after those data originally were due. Such restatements and recalculations increase our costs for complying with the laws and regulations governing the Medicaid Drug Rebate program and could result in an overage or underage in our rebate liability for past quarters. Price recalculations also may affect the ceiling price at which we are required to offer our products under the 340B program or could require us to issue refunds to 340B covered entities.

Table of Contents

Significant civil monetary penalties can be applied if we are found to have knowingly submitted any false pricing information to CMS, or if we fail to submit the required price data on a timely basis. Such conduct also could be grounds for CMS to terminate our Medicaid drug rebate agreement, in which case federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs. Significant civil monetary penalties also can be applied if we are found to have knowingly and intentionally charged 340B covered entities more than the statutorily mandated ceiling price. We cannot assure you that our submissions will not be found by CMS or HRSA to be incomplete or incorrect.

Additionally, the containment of healthcare costs has become a priority of federal and state governments, and the prices of drugs have been a focus in this effort. The U.S. government, state legislatures, and foreign governments have shown significant interest in implementing cost-containment programs, including price controls, restrictions on reimbursement, and requirements for substitution of generic drugs. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit our net revenue and results. Decreases in third-party reimbursement for NEXLETOL and NEXLIZET or any of our future drug candidates, if approved, or a decision by a third-party payor to not cover NEXLETOL and NEXLIZET or any of our future drug candidates could reduce physician usage of such drugs and have a material adverse effect on our sales, results of operations and financial condition.

The Medicaid Drug Rebate Program, or MDRP, requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the Secretary of the HHS as a condition for states to receive federal matching funds for the manufacturer's outpatient drugs furnished to Medicaid patients. The ACA made several changes to the MDRP, including increasing pharmaceutical manufacturers' rebate liability by raising the minimum basic Medicaid rebate percentage on most branded prescription drugs of average manufacturer price, or AMP, and adding a new rebate calculation for "line extensions" (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded products, as well as potentially impacting their rebate liability by modifying the statutory definition of AMP. The ACA also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers to pay rebates on Medicaid managed care utilization and by enlarging the population potentially eligible for Medicaid drug benefits. Pricing and rebate programs must also comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990.

In 2010, the ACA became law in the United States. The goal of the ACA is to reduce the cost of healthcare and substantially change the way healthcare is financed by both governmental and private insurers. The ACA, among other things, increases minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs and biologic products, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

In addition, other legislative and regulatory changes have been proposed and adopted in the United States since the ACA was enacted:

•On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces.

•On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs.

•In August 2022, the Inflation Reduction Act of 2022 (the “IRA”) was signed into law. The IRA includes several provisions that will impact our business to varying degrees, including provisions that create a $2,000 out-of-pocket cap for Medicare Part D beneficiaries, impose new manufacturer financial liability on all drugs in Medicare Part D, allow the U.S. government to negotiate Medicare Part B and Part D pricing for certain high-cost drugs and biologics without generic or biosimilar competition, require companies to pay rebates to Medicare for drug prices that increase faster than inflation, and delay until January 1, 2032 the rebate rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. Further, under the IRA, orphan drugs are exempted from the Medicare drug price negotiation program, but only if they have one orphan designation and for which the only approved indication is for that disease or condition. If a product receives multiple orphan designations or has multiple approved indications, it may not qualify for the orphan drug exemption. The implementation of the IRA is currently subject to ongoing litigation challenging the constitutionality of the IRA’s Medicare drug price negotiation program. The implementation of the IRA is currently subject to ongoing litigation challenging the constitutionality of the IRA’s Medicare drug price negotiation program. The effect of IRA on our business and the healthcare industry in general is not yet known.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, established the Medicare Part D program to provide a voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities that provide coverage of outpatient prescription drugs. Unlike Medicare Parts A and B, Part D coverage is not standardized. While all Medicare drug plans must give at least a standard level of coverage set by Medicare, Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. These Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government payment for some of the costs of prescription drugs may increase demand for NEXLETOL and NEXLIZET or any future drug candidates for which we may obtain marketing approval. However, any negotiated prices for NEXLETOL and NEXLIZET or any future drugs covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

For a drug product to receive federal reimbursement under the Medicaid or Medicare Part B programs or to be sold directly to U.S. government agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer. As of 2010, the ACA expanded the types of entities eligible to receive discounted 340B pricing, although, under the current state of the law, with the exception of children's hospitals, these newly eligible entities will not be eligible to receive discounted 340B pricing on orphan drugs. In addition, as 340B drug pricing is determined based on AMP and Medicaid rebate data, the revisions to the Medicaid rebate formula and AMP definition described above could cause the required 340B discount to increase. It is unclear how these developments may impact the sale of our current and future products and the rates that we may charge in the future. In addition, legislation may be introduced that, if passed, would further expand the 340B program to additional covered entities or would require participating manufacturers to agree to provide 340B discounted pricing on drugs used in an inpatient setting.

The Health Resources and Services Administration, or HRSA, which administers the 340B program, issued a final regulation regarding the calculation of the 340B ceiling price and the imposition of civil monetary penalties on manufacturers that knowingly and intentionally overcharge covered entities, which became effective on January 1, 2019. We also are required to report our 340B ceiling prices to HRSA on a quarterly basis. Implementation of the civil monetary penalties regulation and the issuance of any other final regulations and guidance could affect our obligations under the 340B program in ways we cannot anticipate. In addition, legislation may be introduced that, if passed, would further expand the 340B program to additional covered entities or would require participating manufacturers to agree to provide 340B discounted pricing on drugs used in the inpatient setting. Recently, there have also been several changes to the 340B drug pricing program. On November 3, 2023, the U.S. District Court of South Carolina issued an opinion in Genesis Healthcare Inc. v. Becerra et al. that may lead to an expansion of the scope of patients eligible to access prescriptions at 340B pricing. The outcome of this judicial proceeding is uncertain. We continue to review developments impacting the 340B program.

In recent years, additional laws have resulted in direct or indirect reimbursement reductions for certain Medicare providers, including:

•The Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year and, due to subsequent legislative amendments to the statute, will remain in effect through 2031.

•The American Taxpayer Relief Act of 2012, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

•On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. Due to the Statutory Pay-As-You-Go Act of 2010, estimated budget deficit increases resulting from the American Rescue Plan Act of 2021, and subsequent legislation, Medicare payments to providers will be further reduced starting in 2025 absent further legislation. These laws and regulations may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our approved products or future product candidates for which we may obtain

Table of Contents

regulatory approval or the frequency with which any such approved product or future product candidate is prescribed or used.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices.Specifically, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, and review the relationship between pricing and manufacturer patient support programs.

President Biden has issued multiple executive orders that have sought to reduce prescription drug costs. In February 2023, HHS also issued a proposal in response to an October 2022 executive order from President Biden that includes a proposed prescription drug pricing model that will test whether targeted Medicare payment adjustments will sufficiently incentivize manufacturers to complete confirmatory trials for drugs approved through FDA’s accelerated approval pathway. Although a number of these and other proposed measures may require authorization through additional legislation to become effective, and the Biden administration may reverse or otherwise change these measures, both the Biden administration and Congress have indicated that they will continue to seek new legislative measures to control drug costs.

We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. Federal Government will pay for healthcare drugs and services, which could result in reduced demand for our products or drug candidates or additional pricing pressures.

Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain drug access and marketing cost disclosure and transparency measures, and designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, financial condition, results of operations and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our drugs or put pressure on our drug pricing, which could negatively affect our business, financial condition, results of operations and prospects.

These laws, and future state and federal healthcare reform measures may be adopted in the future, any of which may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for NEXLETOL and NEXLIZET or any future drug candidates for which we may obtain regulatory approval or the frequency with which NEXLETOL and NEXLIZET or any such drug candidate is prescribed or used.

Other Healthcare Laws

For our drugs and any future drug candidates that obtain regulatory approval and are marketed in the U.S., our arrangements with third-party payors, customers, and other third parties may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell, and distribute NEXLETOL and NEXLIZET or any future products candidates for which we obtain marketing approval. Federal enforcement agencies also have showed increased interest in pharmaceutical companies’ product and patient assistance programs, including reimbursement and co-pay support services, and a number of investigations into these programs have resulted in significant civil and criminal settlements. In addition, we may be subject to health information privacy and security regulation by U.S. federal and state governments and foreign jurisdictions in which we conduct our business. In the U.S., these laws include, without limitation, state and federal anti-kickback, false claims, physician transparency, and patient data privacy and security laws and regulations, including but not limited to those described below:

•The federal Anti-Kickback Statute makes it illegal for any person, including a prescription drug manufacturer (or a party on its behalf) to, knowingly and willfully offer, solicit, receive, or pay remuneration (including any kickback, bribe, or rebate), directly or indirectly, in cash or in kind, that is intended to induce or reward, or in return for, either the referral of an individual for, or the purchase, order, or recommendation of, any good or service, for which payment may be made, in whole or in part, under federal healthcare programs such as the Medicare and Medicaid programs. Violations of this law are subject to civil and criminal fines and penalties for each violation, plus up to three times the remuneration involved, imprisonment, administrative civil monetary penalties, and exclusion from participation in government healthcare programs. In addition, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or

Table of Contents

fraudulent claim for purposes of the FCA. The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers, on the one hand, and prescribers, purchasers, and formulary managers, on the other. Although there are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases, or recommendations may be subject to scrutiny if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does not make the conduct per se illegal under the Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances.

•The federal civil and criminal false claims laws, including the federal False Claims Act, impose criminal and civil penalties, and authorizes civil whistleblower or qui tam actions, against individuals or entities (including manufacturers) for, among other things, knowingly presenting, or causing to be presented false or fraudulent claims for payment by a federal healthcare program; making, using, or causing to be made or used, a false statement or record material to payment of a false or fraudulent claim or obligation to pay or transmit money or property to the federal government; or knowingly concealing or knowingly and improperly avoiding or decreasing an obligation to pay money to the federal government. The government may deem manufacturers to have "caused" the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. Claims which include items or services resulting from a violation of the federal Anti-Kickback Statute are false or fraudulent claims for purposes of the False Claims Act. The federal False Claims Act also permits a private individual acting as a “whistleblower” to bring actions on behalf of the federal government alleging violations of the federal False Claims Act and to share in any monetary recovery. Our marketing and activities relating to the reporting of wholesaler or estimated retail prices for NEXLETOL and NEXLIZET or any future product candidates, the reporting of prices used to calculate Medicaid rebate information, and other information affecting federal, state, and third-party reimbursement for NEXLETOL and NEXLIZET or any future product candidates, and the sale and marketing of NEXLETOL and NEXLIZET and any future product candidates, are subject to scrutiny under this law.

•The anti-inducement law, which prohibits, among other things, the offering or giving of remuneration, which includes, without limitation, any transfer of items or services for free or for less than fair market value (with limited exceptions), to a Medicare or Medicaid beneficiary that the person knows or should know is likely to influence the beneficiary's selection of a particular supplier of items or services reimbursable by a federal or state governmental program.

•The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private), willfully obstructing a criminal investigation of a healthcare offense, and knowingly or willfully falsifying, concealing or covering up by any trick or device a material fact, or making any materially false, fictitious, or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items, or services relating to healthcare matters. Similar to the U.S. federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the healthcare fraud statute implemented under HIPAA or specific intent to violate it in order to have committed a violation.

•HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations, which impose, among other things, requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses and their business associates, that perform services for them that involve the use, or disclosure of, individually identifiable health information, relating to the privacy, security, and transmission of individually identifiable health information without appropriate authorization, including mandatory contractual terms and required implementation of technical safeguards of such information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damage or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys' fees and costs associated with pursuing federal civil actions.

•The federal false statements statute prohibits knowingly and willfully falsifying, concealing, or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items, or services.

•Federal price reporting laws require drug manufacturers to calculate and report complex pricing metrics to government programs, where such reported prices may be used in the calculation of reimbursement and/or discounts on approved products.

•Federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers.

•The federal Physician Payments Sunshine Act, or Sunshine Act, enacted as part of the ACA, and its implementing regulations, require certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children's Health Insurance Program (with certain exceptions) to report annually to the HHS under the Open Payments Program, information related to payments and other "transfers of value" provided to physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors), certain other licensed health care practitioners and teaching hospitals, and ownership and investment interests held by physicians and their immediate family members.

•Analogous state and foreign laws and regulations, such as state anti-kickback, false claims laws, consumer protection, and unfair competition laws, which may apply to pharmaceutical business practices, including but not limited to, research, distribution, sales, and marketing arrangements as well as submitting claims involving healthcare items or services reimbursed by any third-party payor, including commercial insurers. Such laws are enforced by various state agencies and through private actions. Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant federal government compliance guidance that otherwise restricts payments that may be made to healthcare providers and other potential referral sources, require drug manufacturers to report information related to pricing and marketing information, such as the tracking and reporting of gifts, compensations, and other remuneration and items of value provided to physicians and other healthcare providers and entities, require the registration of pharmaceutical sales representatives, and restrict marketing practices or require disclosure of marketing expenditures. State and foreign laws also govern the privacy and security of health information in certain circumstances. Such data privacy and security laws may differ from one another in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

In the United States, there is a growing body of stringent privacy and data security legislation. In California, for example, the California Consumer Privacy Act, or CCPA, was enacted in June 2018, became effective on January 1, 2020, and became subject to enforcement by the California Attorney General's office on July 1, 2020. The CCPA broadly defines personal information, gives California residents expanded privacy rights and protections, and places stringent privacy and security obligations on business covered by the law. Further, the California Privacy Rights Act, or CPRA, amended the CCPA and as of January 1, 2023, created additional obligations with respect to processing and safeguarding personal information. The CCPA provides for civil penalties for violations and a private right of action for data breaches. Among other provisions, the CCPA requires covered "businesses" to provide certain disclosures to consumers about their data collection, use and sharing practices, and to provide affected California residents with ways to opt-out of certain sales or sharing of personal information. While there is an exception for protected health information that is subject to HIPAA and clinical trial regulations, the CCPA may impact our business activities if we become a "business" regulated by the scope of the CCPA or a service provider to a regulated business.

In addition to the CCPA, new privacy and data security laws have been enacted in numerous other states and have been proposed in even more states as well as in the U.S. Congress, reflecting a trend toward more stringent privacy legislation in the U.S., which may accelerate. Furthermore, a smaller number of states have passed or are considering laws that are specifically focused upon the protection of consumer health data, such as Washington’s My Health My Data Act. The effects of state and federal privacy laws are potentially significant and may require us to modify our data processing practices and policies and to incur substantial costs and potential liability in an effort to comply with such legislation.

In the U.S., to help patients access our approved products, we may utilize programs to assist them, including patient assistance programs and co-pay coupon programs for eligible patients. PAPs are regulated by and subject to guidance from CMS OIG. In addition, at least one insurer has directed its network pharmacies to no longer accept co-pay coupons for certain specialty drugs the insurer identified. Our co-pay coupon programs could become the target of similar insurer actions. In September 2014, the OIG of the HHS issued a Special Advisory Bulletin warning manufacturers that they may be subject to sanctions under the federal anti-kickback statute and/or civil monetary penalty laws if they do not take appropriate steps to exclude Part D beneficiaries from using co-pay coupons. Accordingly, companies exclude these Part D beneficiaries from using co-pay coupons.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a

Table of Contents

number of investigations, prosecutions, convictions, and settlements in the healthcare industry. In November 2020, the OIG issued a Fraud Alert highlighting its view that pharmaceutical promotional speaker programs can pose a high risk of fraud and abuse. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations, or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other related governmental regulations that may apply to us, we may be subject to significant civil, criminal, and administrative penalties, damages, fines, individual imprisonment, disgorgement, exclusion of drugs from government funded healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, diminished profits and future earnings, and the curtailment or restructuring of our operations, as well as additional oversight, and reporting obligations if we become subject to a corporate integrity agreement or similar settlement to resolve allegations of non-compliance with these laws. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil, or administrative sanctions, including exclusions from government funded healthcare programs, which may also adversely affect our business. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company's attention from the business.

European Union Regulatory Considerations

In the European Union, or EU, NILEMDO and NUSTENDI and any other of our product candidates are also subject to extensive regulatory requirements. As in the United States, medicinal products can be marketed only if a marketing authorization from the competent regulatory agencies has been obtained.

In the event we conduct clinical trials in the European Economic Area, or EEA, and United Kingdom, or UK, we will be subject to additional data protection restrictions, such as the GDPR (as defined below). The GDPR may increase our responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR. Compliance with the GDPR will be a rigorous and time-intensive process that may increase our cost of doing business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection with our potential European activities.

European Union Drug Development

Similar to the U.S., the various phases of preclinical and clinical research in Europe are subject to significant regulatory controls.

In April 2014, the EU adopted a new Clinical Trials Regulation 536/2014, or the Regulation, which replaced the previous Clinical Trials Directive on January 31, 2022. The new Regulation is directly applicable in all EU Member States meaning no national implementing legislation in each EU Member State is required. The new Regulation seeks to simplify and streamline the approval of clinical trials in the EU. For example, the sponsor can submit a single application for approval of a clinical trial in various Member States via an EU portal. As part of the application process, the sponsor shall propose a reporting Member State, who will coordinate the validation and evaluation of the application. The reporting Member State shall consult and coordinate with the other Member States in which the clinical trial is to take place (such Member States being referred to as the Member States Concerned). If an application is rejected, it can be amended and resubmitted through the EU Portal. If an approval is issued, the sponsor can start the clinical trial in all Member States Concerned. However, a Member State Concerned can, in limited circumstances, declare an "opt-out" from an approval. In such a case, the clinical trial cannot be conducted in that Member State. The Regulation also aims to streamline and simplify the rules on safety reporting and introduces enhanced transparency requirements such as mandatory submission of a summary of the clinical trial results to the EU portal.

Marketing Authorization

In the EU, medicinal products can only be commercialized after obtaining an EU marketing authorization. There are two types of marketing authorizations.

The first is the centralized marketing authorization, which is issued by the European Commission through the centralized procedure, or CP, based on the opinion of the Committee for Medicinal Products for Human Use, or CHMP of the EMA. A centralized marketing authorization is valid throughout the entire territory of the EU, and in the additional Member States of the European Economic Area (Iceland, Liechtenstein and Norway). The CP is mandatory for specific products, including for medicinal products produced by certain biotechnological processes, advanced-therapy medicinal products (gene-therapy, somatic cell-therapy or tissue-engineered medicines), products designated as orphan medicinal drugs, and medicinal drugs containing a new active substance indicated for the treatment of HIV or AIDS, cancer, neurodegenerative disorders, diabetes,

Table of Contents

auto-immune and other immune dysfunctions, and viral diseases. The CP is optional for drugs containing a new active substance not yet authorized in the EU, or for drugs that constitute a significant therapeutic, scientific, or technical innovation or which are in the interest of public health in the EU.

National marketing authorizations, which are issued by the competent authorities of the Member States of the EU and only cover their respective territory, are available for drugs not falling within the mandatory scope of the CP. Where a drug has already been authorized for marketing in a Member State of the EU, this national authorization can be recognized in other Member States through the mutual recognition procedure. If the drug has not received a national authorization in any Member State at the time of application, it can be approved simultaneously in various Member States through the decentralized procedure. Under the decentralized procedure an identical dossier is submitted to the competent authorities of each of the Member States in which authorization is sought, one of which is selected by the applicant as the Reference Member State (RMS). The competent authority of the RMS prepares a draft assessment report, a draft summary of the product characteristics (SmPC), and a draft of the labeling and package leaflet, which are sent to the other Member States (referred to as the Concerned Member States) for their approval. If the Concerned Member States raise no objections, based on a potential serious risk to public health, to the assessment, SmPC, labeling, or packaging proposed by the RMS, the drug is subsequently granted a national marketing authorization in all the Member States (i.e., in the RMS and the Concerned Member States).

Under the above described procedures, before granting the marketing authorization, the EMA or the Competent Authorities of the Member States of the EU make an assessment of the risk benefit balance of the product on the basis of scientific criteria concerning its quality, safety, and efficacy.
