We make statements in this section that are “forward-looking” within the meaning of the federal securities laws. For a complete discussion of such statements and the potential risks and uncertainties that may affect their accuracy, see the “Risk Factors” section of this Form 10-K and the “Overview” and “Liquidity and Capital Resources” sections of this MD&A. Discussions of 2022 items and year-to-year comparisons between 2023 and 2022 are not included, and can be found in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Overview

We are a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol. Since 2012, we have marketed Korlym in the United States for the treatment of patients suffering from hypercortisolism (also known as “Cushing’s syndrome”). In June 2024, we made available an authorized generic version of Korlym for the same indication. Our portfolio of proprietary selective cortisol modulators consists of four structurally distinct series totaling more than 1,000 compounds.

Hypercortisolism (Cushing’s Syndrome)

Our Products. We sell Korlym and a generic version of Korlym in the United States (our “Products”), using sales representatives to call on physicians caring for patients with hypercortisolism. We also have a field-based force of medical science liaisons. We use a specialty pharmacy and a specialty distributor to distribute our Products and provide logistical support to physicians and patients. Our policy is that no patient with hypercortisolism will be denied access to our Products for financial reasons. To help us achieve that goal, we have patient support programs and donate money to independent charitable foundations that help patients pay for all aspects of their hypercortisolism care, whether or not that care includes taking our Products.

Because most people who suffer from hypercortisolism are undiagnosed or inadequately treated, we have developed and continue to refine and expand programs to educate physicians and patients about screening for hypercortisolism and the role our Products can play in treating patients with the disorder. In 2024, we conducted the CATALYST study to determine the prevalence of hypercortisolism in patients with difficult-to-control diabetes (defined as HbA1c of 7.5 percent or higher) despite receiving optimum treatment. Of the 1,057 patients enrolled in the first phase of CATALYST, 23.8 percent were found to have hypercortisolism. These patients were offered the chance to enter CATALYST’s second phase, in which 136 eligible patients were randomized 2:1 to receive either Korlym or placebo for 24 weeks. CATALYST’s primary endpoint was the difference in HbA1c in patients who received Korlym compared to patients who received placebo. Patients who received Korlym exhibited a clinically meaningful and statistically significant improvement in hemoglobin A1c, with a decrease from baseline of 1.47 percent, compared to a decrease of 0.15 percent in patients who received placebo (p-value: 0.0001). The safety profile of Korlym in CATALYST was consistent with the medication’s label: No new side effects or adverse events were identified.

The CATALYST data will help physicians better identify patients with hypercortisolism and determine their optimal treatment.

Relacorilant. We are developing our proprietary, selective cortisol modulator, relacorilant, as a treatment for patients with hypercortisolism. Relacorilant shares Korlym’s affinity for the GR but, unlike Korlym, has no affinity for the PR and so is not the “abortion pill” and does not cause other effects associated with PR affinity, including endometrial thickening and vaginal bleeding. Because relacorilant does not meaningfully increase cortisol levels, it does not cause hypokalemia (low potassium), a potentially serious condition that is a leading cause of patients stopping treatment with Korlym. Forty-four percent of patients in Korlym’s pivotal trial experienced hypokalemia. Unlike all other medications used to treat hypercortisolism, relacorilant does not prolong the heart’s QT interval, a potentially deadly off-target effect.

In December 2024, we submitted an NDA to the FDA seeking approval to market relacorilant as a treatment for patients with endogenous hypercortisolism. The NDA is based on positive results from our pivotal trial “GRACE”, as well as confirmatory evidence from our Phase 3 “GRADIENT” trial, our Phase 3 long-term extension study and our Phase 2 study. In

32

all of these trials, patients exhibited clinically meaningful improvements in a wide range of hypercortisolism signs and symptoms, including hypertension, glucose control, weight and body composition. Relacorilant was well-tolerated in all of the trials. Notably, patients did not experience some of the serious adverse events that can arise in patients taking Korlym or other currently approved treatments.

The GRACE trial had two-parts. The first, open-label phase enrolled 152 patients with any etiology of hypercortisolism. Each patient received relacorilant for 22 weeks. Patients who exhibited pre-specified improvements in either hypertension, hyperglycemia or both symptoms proceeded to GRACE’s second, double-blind, randomized withdrawal phase, in which half of the patients continued to receive relacorilant and half received placebo for 12 weeks. GRACE’s primary endpoint was the number of patients in the relacorilant group who lost blood pressure control compared to the number who lost blood pressure control in the placebo group.

In the open-label phase, patients experienced clinically meaningful and statistically significant improvements in a wide-array of hypercortisolism signs and symptoms, including hypertension, hyperglycemia, weight, waist circumference, fat and lean body mass, cognition and Cushing’s Quality of Life score. Rapid and sustained improvements in systolic blood pressure (“SBP”) and diastolic blood pressure (“DBP”) were observed in all patients with hypertension, with an improvement in mean SBP of 7.9 mm Hg and mean DBP of 5.4 mm Hg at 22 weeks (p-values: 0.0001). During the open-label phase, 63 percent of patients with hypertension met the study’s response criteria. The improvements were even greater in the patients with hypertension who entered the randomized withdrawal phase, with reductions in SBP of 12.6 mm Hg and DBP of 8.3 mm Hg (p-values: 0.0001). To ensure accuracy, hypertension was measured by 24-hour ambulatory blood pressure monitoring (“ABPM”).

Glucose metabolism was measured by several diagnostic tests, including the oral glucose tolerance test (glucose area under the curve or AUCglucose), hemoglobin A1c (HbA1c) and fasting glucose. In the open-label phase, clinically meaningful and statistically significant improvements in glucose metabolism were observed in patients with diabetes or impaired glucose tolerance (i.e., pre-diabetes), with reductions in AUCglucose of 3.3 h*mmol/L, HbA1c of 0.3 percent and fasting glucose of 12.4 mg/dL at 22 weeks (p-values: 0.0001, 0.03, 0.03, respectively). During the open-label phase, 50 percent of patients with hyperglycemia met the study’s response criteria. Patients with hyperglycemia who entered the randomized withdrawal phase exhibited more pronounced improvements, with reductions in AUCglucose of 6.2 h*mmol/L, HbA1c of 0.7 percent and fasting glucose of 25.2 mg/dL at 22 weeks (p-values: 0.0001, 0.0001, 0.006, respectively).

GRACE met its primary endpoint. Patients with hypertension who were switched to placebo in the randomized withdrawal phase were significantly more likely to lose blood pressure control than were patients who continued to receive relacorilant (odds ratio: 0.17; p-value: 0.02). Patients who continued to receive relacorilant also maintained their improvements in hyperglycemia, waist circumference, fat and lean tissue mass, while patients who received placebo experienced a significant worsening of hypercortisolism signs and symptoms.

Our Phase 3 GRADIENT study enrolled patients with hypercortisolism caused by adrenal adenomas or adrenal hyperplasia. These patients have a more gradual decline than patients with other etiologies of hypercortisolism, although their health outcomes are ultimately poor. GRADIENT enrolled 137 patients with hypercortisolism and either hypertension, hyperglycemia or both. Patients were randomized on a double-blind basis 1:1 to receive either relacorilant or placebo for 22 weeks. The trial’s primary endpoint was the improvement compared to placebo in systolic blood pressure with glycemic control, weight and body composition as secondary endpoints.

Patients in GRADIENT who received relacorilant exhibited clinically meaningful and statistically significant improvements in hypertension, hyperglycemia, weight and body composition compared to baseline, while patients who received placebo did not.

GRADIENT patients with hypertension who received relacorilant experienced a reduction in systolic blood pressure of 6.6 mm Hg (p-value 0.012) compared to baseline. The reduction in patients who received placebo was 2.1 mm Hg (p-value: ns) compared to baseline. The comparison between those who received relacorilant and placebo was not statistically significant. During the study, five patients who received placebo required rescue therapy with anti-hypertension medications, compared to one patient who received relacorilant. To ensure accuracy, hypertension was measured by 24-hour ambulatory blood pressure monitoring.

GRADIENT patients with hyperglycemia who received relacorilant experienced clinically meaningful and statistically significant improvements in glucose metabolism, including fasting glucose (placebo-adjusted reduction of 22.2 mg/dL; p-value 0.002), area under the curve of the oral glucose tolerance test (placebo-adjusted reduction of 2.6 h*mmol/L; p-value 0.046) and hemoglobin A1c (placebo-adjusted reduction of 0.3 percent; p-value 0.019), compared to those who received placebo.

33

Patients in GRADIENT who received relacorilant experienced clinically meaningful and statistically significant improvements in body weight (placebo-adjusted reduction of 3.9 kg; p-value: 0.0001) and visceral adipose fat mass and volume (p-values: 0.018 and 0.016, respectively), compared to patients who received placebo.

Relacorilant was well-tolerated in GRADIENT, with side effects consistent with its other clinical trials. The most common adverse events were mild-to-moderate nausea, edema, pain in the extremities and back, and fatigue – all symptoms associated with the “cortisol withdrawal” many patients experience when cortisol activity reverts to a more normal level, following surgery or the start of medical therapy for hypercortisolism. Importantly, there were no relacorilant-induced instances of hypokalemia, endometrial hypertrophy or drug-induced vaginal bleeding, adrenal insufficiency or QT prolongation.

Patients who completed our Phase 2 study or the GRACE or GRADIENT trials were eligible to enter our open-label, long-term extension study. Of the 116 patients who chose to do so, the duration of the treatment has been up to six years. In December 2024, we announced that patients who remained in the study for 24 months exhibited, at that time, further clinically meaningful and statistically significant reductions in systolic (10.0 mm Hg; p-value: 0.012) and diastolic blood pressure (7.3 mm Hg; p-value: 0.016), compared to their blood pressure at entry into the long-term extension study. These patients had also maintained response in other cardiometabolic measures, such as glycemic control and body weight. Consistent with its known safety profile, relacorilant was well-tolerated.

The FDA and the EC have designated relacorilant as an orphan drug for the treatment of hypercortisolism. In the United States, relacorilant’s orphan designation confers tax credits, reduced regulatory fees and, provided we obtain approval for the treatment of patients with hypercortisolism, seven years of exclusive marketing rights. Benefits of orphan drug designation by the EC are similar, but also include protocol assistance from the EMA, access to the centralized marketing authorization procedure in the EU and, if we obtain approval, ten years of exclusive marketing rights in the EU for the treatment of patients with hypercortisolism.

Oncology

There is substantial evidence that cortisol activity at the GR reduces the efficacy of certain anti-cancer therapies and that modulating cortisol’s activity may help anti-cancer treatments achieve their intended effect. In some cancers, cortisol retards cellular apoptosis – the tumor-killing effect many treatments are meant to stimulate. In other cancers, cortisol activity promotes tumor growth. Cortisol also suppresses the body’s immune response; activating – not suppressing – the immune system is beneficial in fighting certain cancers. Many types of solid tumors express the GR and are potential targets for cortisol modulation therapy, among them ovarian, adrenal and prostate cancer.

Relacorilant in Patients with Platinum-Resistant Ovarian Cancer. We are conducting a pivotal Phase 3 trial (“ROSELLA”) of our proprietary, selective cortisol modulator, relacorilant combined with nab-paclitaxel as a treatment for patients with platinum-resistant ovarian cancer. Enrollment in ROSELLA is complete. Three hundred eighty-one women with recurrent, platinum-resistant ovarian cancer were randomized 1:1 to receive either 150 mg of relacorilant intermittently in addition to nab-paclitaxel or nab-paclitaxel monotherapy. ROSELLA has dual primary endpoints – progression free survival (“PFS”) and overall survival (“OS”). ROSELLA will have a statistically positive outcome if either endpoint is met. Patients enrolled in ROSELLA were required to have received prior bevacizumab therapy, which is the approved standard of care for patients with platinum-resistant ovarian cancer. Women with a history of tumors that do not respond to initial platinum-based treatments (i.e., women with “primary platinum-refractory” disease) and those who have received more than three prior lines of therapy were excluded.

ROSELLA seeks to replicate the positive results of our Phase 2 trial, a 178-patient, controlled, multi-center, trial of relacorilant combined with nab-paclitaxel in patients with platinum-resistant ovarian cancer. Phase 2 study participants were randomized to one of three treatment arms: 60 women received 150 mg of relacorilant intermittently (the day before, the day of and the day after their weekly nab-paclitaxel infusion) and 58 women received a daily relacorilant dose of 100 mg per day in addition to nab-paclitaxel. Sixty women received nab-paclitaxel alone. The trial’s primary endpoint was PFS.

Patients in both of the relacorilant plus nab-paclitaxel treatment arms of the Phase 2 trial experienced longer PFS than did the patients who received nab-paclitaxel alone. Patients who received a higher dose of relacorilant intermittently exhibited a statistically significant improvement in median PFS (5.6 months versus 3.8 months, hazard ratio: 0.66; p-value: 0.038). Patients who received a lower dose of relacorilant daily exhibited a median PFS that was 1.5 months longer than did the patients who received nab-paclitaxel alone (5.3 months versus 3.8 months, hazard ratio: 0.83; p-value: not significant). Patients who received relacorilant intermittently also had a longer median duration of response (“DoR”) (5.6 months versus 3.7 months, hazard ratio: 0.36; p-value: 0.006) compared to those who received nab-paclitaxel alone. Patients who received relacorilant intermittently also lived longer (median OS: 13.9 months versus 12.2 months, hazard ratio: 0.67; p-value: 0.066) compared to those who received nab-paclitaxel alone.

34

Notably, the addition of relacorilant to treatment with nab-paclitaxel did not create an additional adverse event burden for patients. Safety and tolerability of relacorilant and nab-paclitaxel combination treatment were comparable to the safety and tolerability of nab-paclitaxel monotherapy.

The final analysis from our Phase 2 trial was published in the Journal of Clinical Oncology (Colombo et al., 2023), the premiere journal of the American Society of Clinical Oncology (ASCO).

Relacorilant in Patients with Adrenal Cancer with Cortisol Excess. We have completed an open-label, Phase 1b trial of relacorilant plus the PD-1 checkpoint inhibitor pembrolizumab in 14 patients with metastatic or unresectable adrenal cancer whose tumors produce cortisol. Patients with this form of adrenal cancer virtually never respond to immunotherapy and their disease progresses very rapidly. Our trial sought to test whether adding relacorilant to pembrolizumab therapy would reduce cortisol-activated immune suppression sufficiently to help the patient’s immune system reduce or eradicate the patient’s tumors while also reducing the symptoms of hypercortisolism caused by the tumors’ hypersecretion of cortisol. Although patients exhibited significant improvements in their symptoms of hypercortisolism, such as reductions in hypertension and hyperglycemia, their tumor progression did not slow. The combination of relacorilant with pembrolizumab was well-tolerated. We are evaluating next steps to better understand the role cortisol modulation may play in combination with immunotherapies directed to other tumor types and earlier stages of cancer.

Relacorilant in Patients with Prostate Cancer. Androgen deprivation is the standard treatment for prostate cancer because androgens stimulate prostate tumor growth. Prostate cancer tumors eventually escape androgen deprivation therapy; one of the prime reasons is that these tumors begin to be stimulated by cortisol’s activity. Combining a cortisol modulator with an androgen modulator may block this escape route. Our collaborators at the University of Chicago have initiated a randomized, placebo-controlled Phase 2 trial of relacorilant plus enzalutamide in patients with prostate cancer, pre-prostatectomy. We are providing relacorilant and placebo for the study. Patents we have licensed from the University of Chicago cover the use of relacorilant combined with anticancer agents, including enzalutamide, to treat patients with this disease.

Amyotrophic Lateral Sclerosis (“ALS”)

ALS, also known as Lou Gehrig’s disease, is a devastating neuromuscular illness. Our selective cortisol modulator dazucorilant improved motor performance and reduced neuroinflammation and muscular atrophy in an animal model of ALS. Following these compelling results, we initiated a Phase 2 trial (“DAZALS”) of dazucorilant in patients with ALS. Two hundred forty-nine patients were randomized on a double-blind basis 1:1:1 to receive either 150 mg of dazucorilant, 300 mg of dazucorilant or placebo daily for 24 weeks. Upon completion of the trial, patients were eligible to enter an open-label, long-term extension study, in which they receive 300 mg of dazucorilant for up to 132 weeks. DAZALS did not meet its primary endpoint, which was the change from baseline in the ALS Functional Rating Scale-Revised (ALSFRS-R) in patients who received dazucorilant compared to those who received placebo. Patients who received dazucorilant also experienced substantially more gastrointestinal upset at the onset of treatment than did those who received placebo. During the 24-week study, no deaths (0/83) were observed in the 300 mg dazucorilant arm, compared to 5 deaths (5/82) in the placebo group (p-value: 0.02). The open-label, long-term extension study, which enrolled 118 patients, will continue. Pursuant to the study protocol, overall survival will be assessed again in March 2025. The FDA has granted dazucorilant Fast Track Designation and orphan drug status for the treatment of ALS in the United States.

Metabolic Diseases

Liver Disease. Metabolic dysfunction-associated steatohepatitis (“MASH”) is an advanced form of metabolic dysfunction-associated fatty liver disease that afflicts millions of patients and is a leading cause of liver-related mortality. Our Phase 1b trial of the selective cortisol modulator miricorilant as a potential treatment for MASH identified a dosing regimen that reduced liver fat, improved liver health and key metabolic and lipid measures and was well-tolerated. Following these compelling results, we initiated a randomized, double-blind, placebo-controlled, Phase 2b trial (“MONARCH”) of miricorilant in patients with MASH in October 2023. MONARCH has two patient cohorts. Cohort A has a planned enrollment of 120 patients with biopsy-confirmed MASH, randomized 2:1 to receive either 100 mg of miricorilant twice weekly or placebo for 48 weeks. The primary endpoint of Cohort A is reduction in liver fat, with MASH resolution and fibrosis improvement as key secondary endpoints. Cohort B has a planned enrollment of 75 patients with presumed MASH, randomized 2:1 to receive either 100 mg of miricorilant twice weekly for 6 weeks and then 200 mg of miricorilant twice weekly for 18 weeks or placebo for 24 weeks. The primary endpoint of Cohort B is reduction in liver fat.

Development of Other Selective Cortisol Modulators

We continue to create new selective cortisol modulators, the most promising of which we advance towards the clinic.

Inflation Reduction Act of 2022

The Inflation Reduction Act of 2022 (“IRA”) was enacted on August 16, 2022. The IRA includes provisions requiring manufacturers to pay a rebate to the Centers for Medicare & Medicaid Services (“CMS”) if the price of a Medicare Part B or Part D drug increases faster than the rate of inflation. In addition, beginning in 2025, the IRA will also shift a significant portion of the Medicare beneficiary costs currently borne by the government and beneficiaries to manufacturers. We anticipate this provision will limit the revenue we receive from Medicare patients and may materially reduce our profits. The IRA permits CMS to negotiate prices for certain high-expenditure Medicare Part B or Part D drugs.

The IRA also imposes a one percent excise tax on certain share repurchases and introduces a 15 percent corporate alternative minimum tax on adjusted financial statement income. The corporate alternative minimum tax became effective for us on January 1, 2024. We do not expect either of these provisions to significantly affect our consolidated financial statements.

Please see the risk factor under Item 1A of this Annual Report on Form 10-K, “New laws, government regulations, or changes to existing laws and regulations could make it difficult or impossible for us to obtain acceptable prices or adequate insurance coverage and reimbursement for our Products, which would adversely affect our results of operations and financial position.”

Results of Operations

Net Product Revenue – Net product revenue is gross product revenue from sales to our customers less deductions for estimated government rebates and chargebacks, patient co-pay assistance program, discounts provided to our specialty distributor for prompt payment and reserves for expected returns.

Net product revenue was $675.0 million for the year ended December 31, 2024, compared to $482.4 million and $401.9 million for the years ended December 31, 2023 and 2022, respectively. Higher sales volume accounted for 79.4 percent of the increase for the year ended December 31, 2024, with the remaining growth due to a price increase effective January 1, 2024.

Cost of sales – Cost of sales includes the cost of API, tableting, packaging, personnel, overhead, stability testing and distribution.

Cost of sales was $10.9 million for the year ended December 31, 2024, compared to $6.5 million and $5.4 million for the years ended December 31, 2023 and 2022, respectively. Cost of sales as a percentage of revenue was 1.6 percent, 1.3 percent and 1.3 percent for each of the years ended December 31, 2024, 2023 and 2022, respectively. The increase of cost of sales as a percentage of revenue for the year ended December 31, 2024 compared to 2023 was primarily due to increased manufacturing and distribution costs.

Research and development expense – Research and development expense includes the cost of (1) clinical trials, (2) recruiting and compensating development personnel, (3) manufacturing investigational drug product (4) preclinical studies, (5) drug discovery research and (6) the development of new drug formulations and manufacturing processes.

Research and development expense was $246.9 million for the year ended December 31, 2024, compared to $184.4 million and $131.0 million for the years ended December 31, 2023 and 2022, respectively. The increase for the year ended December 31, 2024 compared to 2023 was primarily due to increased spending on the advancement and completion of our Cushing’s syndrome and Oncology development programs and increased employee compensation expense to support these activities.

36

It is difficult to predict the timing and cost of development activities, which are subject to many uncertainties and risks, including inconclusive or negative results, slow patient enrollment, adverse side effects and difficulties in the formulation or manufacture of study drugs and lack of drug-candidate efficacy. In addition, clinical development is subject to government oversight and regulations that may change without notice. We expect our research and development expense to be higher in 2025 than in 2024 as we add new clinical trials, assuming success in our existing trials, and our existing trials enroll more patients. Research and development spending in future years will depend on the outcome of our pre-clinical and clinical trials and our development plans.

Selling, general and administrative expense – Selling, general and administrative expense includes (1) compensation of employees, consultants and contractors engaged in commercial and administrative activities, (2) the cost of vendors supporting commercial activities and (3) legal and accounting fees.

Selling, general and administrative expense for the years ended December 31, 2024, 2023 and 2022 was $280.3 million, $184.3 million and $152.8 million, respectively. The increase for the year ended December 31, 2024 compared to 2023 was primarily due to increased employee compensation expenses and sales and marketing activities.

We expect our selling, general and administrative expense to be higher in 2025 than in 2024 due to increased commercial and administrative activities to support our increased research and development and marketing efforts.

Interest and other income – Interest and other income for the years ended December 31, 2024, 2023 and 2022 was $24.5 million, $17.3 million and $3.6 million, respectively, and consisted primarily of interest income from marketable securities. The increase for the year ended December 31, 2024 compared to 2023 was due to higher cash and investment balances.

Income tax expense – Income tax expense for the years ended December 31, 2024, 2023, and 2022 was $20.3 million, $18.4 million, and $14.8 million, respectively. The increase for the year ended December 31, 2024 compared to 2023 was primarily due to increased income before income taxes.

Liquidity and Capital Resources

Since 2015, we have relied on revenues from the sale of our Products to fund our operations.

Based on our current plans and expectations, we expect to fund our operations and planned research and development activities over the next 12 months and beyond without needing to raise additional funds, although we may choose to raise additional funds for other reasons. If we were to raise funds, equity financing would be dilutive, debt financing could involve restrictive covenants and funds raised through collaborations with other companies may require us to relinquish certain rights in our product candidates.

As of December 31, 2024, we had cash, cash equivalents and marketable securities of $603.2 million, consisting of cash and cash equivalents of $127.7 million and marketable securities of $475.5 million, compared to cash, cash equivalents and marketable securities of $425.4 million, consisting of cash and cash equivalents of $135.6 million and marketable securities of $289.8 million as of December 31, 2023.

The cash in our bank accounts and our marketable securities could be reduced or our access to them restricted if the financial institutions holding them were to fail or severely adverse conditions were to arise in the markets for public or private debt securities. We have never experienced a material lack of access to cash or material realized losses.

Net cash provided by operating activities for the years ended December 31, 2024, 2023 and 2022 was $198.1 million, $127.0 million and $120.3 million, respectively. The increase for the year ended December 31, 2024 compared to 2023 was primarily due to higher revenue.

Net cash (used in) provided by investing activities for the years ended December 31, 2024, 2023 and 2022 was $(177.6) million, $90.9 million and $(114.3) million, respectively. The change for the year ended December 31, 2024 compared to 2023 was primarily due to investments in marketable securities during 2024 compared to allocation of cash proceeds from maturities of marketable securities towards cash equivalents in anticipation of the closing of our tender offer during 2023.

Net cash used in financing activities was $28.3 million, $148.7 million and $17.3 million for the years ended December 31, 2024, 2023 and 2022, respectively. In the year ended December 31, 2024, we spent $38.0 million acquiring shares of our common stock, comprised of $15.7 million pursuant to our Stock Repurchase Program, $17.0 million acquiring shares of our common stock in connection with the net exercise of employee and director stock options and $5.3 million to satisfy tax withholding requirements from vesting of restricted stock grants, offset by $5.5 million received in connection with our ESPP and $4.2 million net cash received from the exercise of stock options. For the year ended December 31, 2023, we spent $154.5 million acquiring shares of our common stock, comprised of $145.4 million pursuant to our tender offer, $7.4

37

million acquiring shares of our common stock in connection with the net exercise of employee and director stock options and $1.7 million to satisfy tax withholding requirements from vesting of restricted stock grants, offset by $3.8 million received in connection with our ESPP and $2.0 million net cash received from the exercise of stock options.

As of December 31, 2024, we had retained earnings of $543.7 million.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with U.S. GAAP, which requires us to make estimates and judgments that affect the amount of assets, liabilities and expenses we report. We base our estimates on historical experience and on other assumptions we believe to be reasonable. Actual results may differ from our estimates. Our significant accounting policies are described in Note 1, Basis of Presentation and Summary of Significant Accounting Policies, of the Notes to Consolidated Financial Statements included in Part IV of this Annual Report on Form 10-K. We believe the following accounting estimates and policies to be critical:

Net Product Revenue

To determine net product revenue, we deduct from sales the cost of our patient co-pay assistance program and our estimates of (i) government chargebacks and rebates, (ii) discounts provided to our specialty distributor (“SD”) for prompt payment and (iii) reserves for expected returns. We record these estimates at the time we recognize revenue and update them as new information becomes available. Our estimates take into account our understanding of the range of possible outcomes. If results differ from our estimates, we adjust our estimates, which changes our net product revenue and earnings. We report any changes in the period they become known, even if they concern transactions occurring in prior periods.

Government Rebates

Our Products are eligible for purchase by, or qualifies for reimbursement from, Medicaid, Medicare and other government programs that are eligible for rebates on the price they pay for our Products. To determine the appropriate amount to reserve against these rebates, we identify our Products sold to patients covered by government-funded programs, apply the applicable government discount to these sales, then estimate utilization of such programs by government payors. We (i) deduct this reserve from revenue in the period to which the rebates relate and (ii) include in accrued expenses on our consolidated balance sheet a current liability of equal amount.
