Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Nature of Operations

SpringWorks Therapeutics, Inc., together with its wholly-owned subsidiaries, collectively, the Company, is a commercial-stage biopharmaceutical company applying a precision medicine approach to developing and commercializing life-changing medicines for underserved patient populations suffering from devastating rare diseases and cancer. The Company has a differentiated portfolio of small molecule targeted oncology assets, including one approved product and several clinical candidates, and is advancing programs in both rare tumor types as well as highly prevalent, genetically defined cancers. OGSIVEO® (nirogacestat) is the Company’s first commercial product. OGSIVEO was approved by the United States Food and Drug Administration, or FDA, on November 27, 2023 for the treatment of adult patients with progressing desmoid tumors who require systemic treatment.

The Company has incurred losses and negative operating cash flows since inception and had an accumulated deficit of $982.4 million and $895.0 million, and working capital of $402.9 million and $422.7 million, as of March 31, 2024 and December 31, 2023, respectively. In December 2023, the Company began to generate revenue from sales of OGSIVEO in the United States. For the three months ended March 31, 2024, the Company recorded net revenue of $21.0 million from the sales of OGSIVEO.

The Company had cash, cash equivalents and marketable securities of $573.0 million and $662.6 million as of March 31, 2024 and December 31, 2023, respectively. Based on the Company’s cash, cash equivalents and marketable securities as of March 31, 2024, management estimates that its current liquidity will enable it to meet operating expenses through at least twelve months after the date that these financial statements are issued.

2. Basis of Presentation

The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP, for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission, or SEC, and should be read in conjunction with the Company's consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 27, 2024. The condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, such financial statements reflect all adjustments, consisting solely of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, research and development expenses, valuation of equity-based compensation awards and variable consideration and other relevant inputs impacting the gross and net revenue recognition. Management bases its estimates on historical experience, known trends and other market-specific or relevant factors that it believes to be reasonable under the circumstances. Actual results may differ from those estimates or assumptions. On an ongoing basis, management evaluates its estimates, and adjusts those estimates and assumptions when facts or circumstances change. Changes in estimates are recorded in the period in which they become known.

Summary of Significant Accounting Policies

The Company’s significant accounting policies are described in Note 3 to the Company’s audited consolidated financial statements included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 27, 2024. There have been no significant changes in the Company’s significant accounting policies from those disclosed in its Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 27, 2024.

Recently Adopted Accounting Pronouncements

There were no recently adopted accounting pronouncements that had a material impact on the Company's financial statements.

Total	$	485,344	$	1,191	$	—	$	486,535

The Company’s marketable securities are available-for-sale securities and consist of high-quality, highly liquid debt securities including corporate debt securities, U.S. government securities, non-U.S. government securities, and commercial paper.

The Company’s securities classified as short-term marketable securities mature within one year or less of the balance sheet date. Marketable securities that mature greater than one year from the balance sheet date are classified as long-term. As of March 31, 2024, the Company did not hold any investments with maturity dates greater than five years.

As of, and for the three months ended March 31, 2024, the Company did not have any allowance for credit losses or impairments of its marketable securities.

4. Fair Value Measurements

The fair value of the Company’s financial assets measured on a recurring basis are classified based upon a fair value hierarchy consisting of the following three levels:

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets, or liabilities.

Level 2 — Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the instrument.

Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

Table of Contents

The fair value hierarchy is based on inputs to valuation techniques used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions.

As of March 31, 2024 and December 31, 2023, the Company's financial assets and liabilities measured at fair value on a recurring basis consisted of the following:

5. Collaboration, Licensing and Variable Interest Entities

MapKure

In June 2019, the Company announced the formation of MapKure LLC, or MapKure, an entity jointly owned by the Company and BeiGene Ltd., or BeiGene. BeiGene licensed to MapKure exclusive rights to brimarafenib (BGB-3245), an investigational oral, small molecule selective inhibitor of specific BRAF driver mutations and genetic fusions. MapKure is advancing brimarafenib through clinical development for solid tumor patients harboring BRAF driver mutations and genetic fusions that were observed to be sensitive to the compound in preclinical studies. In addition to the Company’s equity ownership in MapKure, the Company maintains a member on each of MapKure’s joint steering committee and board of directors. The Company also contributes to clinical development and other operational activities for brimarafenib through a service agreement with MapKure.

In conjunction with the formation of MapKure in June 2019, the Company purchased 3,500,000 Series A preferred units of MapKure, or a 25.0% ownership interest, for $3.5 million and in June 2020, the Company purchased an additional 3,500,000 Series A preferred units of MapKure for $3.5 million, increasing its ownership interest to 38.9%, as required by the terms of the Series A unit purchase agreement.

In June 2022, the Company made an additional investment in MapKure and purchased 4,200,000 Series B preferred units of MapKure for $4.2 million, pursuant to the terms of a Series B preferred unit purchase agreement. In January 2023, pursuant to terms of the Series B preferred unit purchase agreement, the Company purchased an additional 2,800,000 Series B preferred units of MapKure for $2.8 million. The ownership interest remained at 38.9%, as required by the terms of the Series B unit purchase agreement.

In January 2024, the Company made an additional investment in MapKure and purchased 8,235,200 Series C preferred units of MapKure for $8.2 million, pursuant to the terms of a Series C preferred unit purchase agreement. The Company is required to make subsequent purchases at each of the second and third closings established by such agreement, in each case for an additional 6,176,400 Series C preferred units of MapKure for $6.2 million. As of March 31, 2024, the Company’s ownership interest in MapKure was 39.7%.

The Company determined that MapKure is a variable interest entity. The Company is not the primary beneficiary, as the Company does not have the power to direct the activities that most significantly impact the economic performance of MapKure. Accordingly, the Company does not consolidate the financial statements of this entity and accounts for this investment using the equity method of accounting based on a one quarter lag.

The Company recognized an equity loss of $1.0 million and $1.3 million for the three-month periods ended March 31, 2024 and March 31, 2023, respectively. The Company’s ownership interest in MapKure is included in Equity method investments. As of March 31, 2024, the Company’s maximum exposure to loss as a result of the Company’s involvement with MapKure is $21.6 million, representing the carrying value of the investment of $9.2 million plus the unfunded obligation of $12.4 million.

GSK Expanded Non-exclusive License and Collaboration Agreement

In September 2022, the Company announced an expansion of its ongoing, non-exclusive clinical collaboration with GSK plc, formerly GlaxoSmithKline plc, or GSK, which originally commenced in June 2019. The announcement coincided with the entry by the Company and GSK into an amended and restated collaboration and license agreement, or the GSK License Agreement, for the potential continued development and commercialization of nirogacestat in combination with either belantamab mafodotin (belamaf), GSK’s antibody-drug conjugate, or ADC, targeting B-cell maturation antigen, or BCMA, or any other cytotoxic ADC targeting BCMA derived from belantamab that is controlled by GSK, either alone as a combination therapy, or together with other pharmaceutical agents.

Pursuant to the terms of the GSK License Agreement and concurrent with the execution of such agreement, the Company entered into a Stock Purchase Agreement with an affiliate of GSK, Glaxo Group Limited, or GGL, under which GGL purchased 2,050,819 shares of the Company’s Common Stock, par value $0.0001 per share, or Common Stock, in a private placement transaction for an aggregate purchase price of approximately $75.0 million, or $36.57 per share. The shares were sold at a 25% premium to the volume-weighted average share price of the Common Stock for a specified 30-day period prior to entering into the Stock Purchase Agreement. The fair value of the Common Stock based on the closing price of Common Stock on the day prior to the effective date of the Stock Purchase Agreement was $55.5 million and was recorded to equity. The $19.5 million of consideration received in excess of the fair value of the Common Stock represents consideration for the license for the potential continued development and commercialization of nirogacestat in combination with GSK compounds, together with the clinical supply of nirogacestat for future belamaf clinical trials and certain research and development costs associated with nirogacestat. The Company recorded the $19.5 million as deferred revenue in September of 2022 and will recognize revenue as the corresponding performance obligation is satisfied in proportion to expenses incurred, including clinical supply and research and

7. Commitments and Contingencies

The Company enters into contracts in the normal course of business for clinical trials, preclinical studies, manufacturing and other services and products for operating purposes. These contracts generally provide for termination following a certain period after notice and therefore the Company believes that non-cancelable obligations under these agreements are not material.

Additionally, the Company has excluded milestone or royalty payments or other contractual payment obligations as the timing and amounts of such obligations are unknown or uncertain.

Contingencies

From time to time, the Company may be involved in disputes or regulatory inquiries that arise in the ordinary course of business. When the Company determines that a loss is both probable and reasonably estimable, a liability is recorded and disclosed if the amount is material to the financial statements taken as a whole. When a material loss contingency is only reasonably possible, the Company does not record a liability, but instead discloses the nature and the amount of the claim, and an estimate of the loss or range of loss, if such an estimate can reasonably be made.

As of March 31, 2024, there was no litigation or contingency with at least a reasonable possibility of a material loss.

8. Equity-Based Compensation

2019 Equity Incentive Plan

The Company's 2019 Stock Option and Incentive Plan, or 2019 Equity Incentive Plan, provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock units, restricted stock awards, unrestricted stock awards and dividend equivalent rights to the Company’s officers, employees, directors and other key persons (including consultants). The number of shares available for issuance under the 2019 Equity Incentive Plan is cumulatively increased each January 1, through and including January 1, 2030, by 5% of the number of shares of Common Stock outstanding on the immediately preceding December 31 or such lesser number of shares as determined by the compensation committee of the Company’s board of directors.

As of March 31, 2024, there were 3,498,653 shares available for issuance in connection with future awards under the 2019 Equity Incentive Plan.

Overview

We are a commercial-stage biopharmaceutical company applying a precision medicine approach to developing and commercializing life-changing medicines for underserved patient populations suffering from devastating rare diseases and cancer. We have a differentiated portfolio of small molecule targeted oncology assets, including one approved product and several clinical candidates, and are advancing programs in both rare tumor types as well as highly prevalent, genetically defined cancers. Our strategic approach and operational excellence across research, translational science and clinical development have enabled us to successfully launch our first product, rapidly advance additional product candidates into late-stage clinical trials and enter into multiple shared-value partnerships with industry leaders to expand our portfolio. From this foundation, we are continuing to build a differentiated, fully-integrated, commercial biopharmaceutical company intensely focused on understanding patients and their diseases in order to develop transformative targeted medicines.

OGSIVEO® (nirogacestat) is our first commercial product. OGSIVEO was approved by the United States Food and Drug Administration, or FDA, on November 27, 2023. OGSIVEO is a novel, oral, selective gamma secretase inhibitor that is the first and only FDA-approved therapy for the treatment of adult patients with progressing desmoid tumors who require systemic treatment.

The FDA approval of OGSIVEO was based on the results from the Phase 3 DeFi trial, which were published in the March 9, 2023 edition of the New England Journal of Medicine. DeFi is a global, randomized (1:1), double-blind, placebo-controlled Phase 3 trial evaluating the efficacy, safety and tolerability of nirogacestat in adult patients with progressing desmoid tumors. The study randomized 142 patients to receive 150 mg of nirogacestat or placebo twice daily. OGSIVEO met the primary endpoint of improving progression-free survival, or PFS, demonstrating a statistically significant improvement for nirogacestat over placebo, with a 71% reduction in the risk of disease progression (hazard ratio (HR) = 0.29 (95% CI: 0.15, 0.55); p< 0.001). Median PFS was not reached in the OGSIVEO arm and was 15.1 months in the placebo arm. Confirmed objective response rate, or ORR, based on RECIST v1.1 was 41% with OGSIVEO versus 8% with placebo (p<0.001); the complete response rate was 7% in the OGSIVEO arm and 0% in the placebo arm. The median time to first response was 5.6 months with OGSIVEO and 11.1 months with placebo. PFS and ORR improvements were in favor of OGSIVEO regardless of baseline characteristics including sex, tumor location, tumor focality, treatment status, previous treatments, mutational status and history of familial adenomatous polyposis. OGSIVEO also demonstrated early and sustained improvements in patient-reported outcomes, including pain, desmoid tumor-specific symptoms, physical/role function and overall health-related quality of life. OGSIVEO exhibited a manageable safety and tolerability profile. The most common adverse events (>15%) reported in patients receiving OGSIVEO were diarrhea, ovarian toxicity, rash, nausea, fatigue, stomatitis, headache, abdominal pain, cough, alopecia, upper respiratory tract infection and dyspnea. Warnings & Precautions include diarrhea, ovarian toxicity, hepatotoxicity, non-melanoma skin cancers, electrolyte abnormalities and embryo-fetal toxicity.

OGSIVEO is the first and only FDA-approved treatment indicated specifically for desmoid tumors. In December 2023, the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Soft Tissue Sarcoma V.3.2023 were updated to recommend nirogacestat as an NCCN Category 1, Preferred treatment option for desmoid tumors.

We are advancing a targeted launch strategy focused on positioning OGSIVEO as the potential standard of care for adult desmoid tumor patients. For the three months ended March 31, 2024, we recorded net product revenue of $21.0 million from sales of OGSIVEO in the United States. On April 4, 2024, we received FDA approval of a Supplemental New Drug Application, or sNDA, providing for the addition of two higher dosage strengths of 150 mg and 100 mg OGSIVEO tablets in new blister packaging, which have been developed to enhance patient convenience with OGSIVEO. The blister packs are expected to be on the market in mid-May 2024.

We are also seeking to expand the reach of OGSIVEO to additional geographies; in February 2024, we submitted and received validation for a Marketing Authorization Application, or MAA, to the European Medicines Agency, or EMA. Beyond the United States and Europe, we continue to evaluate additional territories in which to potentially commercialize OGSIVEO.

We are also evaluating nirogacestat for the treatment of ovarian granulosa cell tumors, or GCT, a subtype of ovarian cancer.

In May 2023, we announced full enrollment of a Phase 2 trial evaluating nirogacestat as a monotherapy in adult patients with recurrent ovarian GCT. We expect to report initial data from the trial in the second half of 2024.

Our second product candidate is mirdametinib, an investigational oral, small molecule MEK inhibitor, currently in development for the treatment of neurofibromatosis type 1-associated plexiform neurofibromas, or NF1-PN, a rare tumor of the peripheral nerve sheath that causes significant pain and disfigurement. We believe that mirdametinib has the potential to offer a best-in-class profile in order to enable the long-term treatment required for this patient population, as compared to other MEK inhibitors. In November 2023, we announced positive topline results from the ReNeu trial, a potentially registrational Phase 2b clinical trial of mirdametinib for pediatric and adult patients with NF1-PN. As of the data cutoff date of September 20, 2023, 52% (29/56) of pediatric patients and 41% (24/58) of adult patients had Blinded Independent Central Review, or BICR, confirmed objective responses within the 24-cycle treatment period (cycle length: 28 days). An additional pediatric patient and two additional adult patients achieved confirmed objective responses after Cycle 24 in the long-term follow up phase of the trial, where patients continue to receive mirdametinib treatment. Median best percent change from baseline in target tumor volume was -42% and -41% in the pediatric and adult cohorts, respectively. As of the data cutoff, the median duration of treatment was 22 months in both the pediatric and adult cohorts. Median duration of response was not reached in either cohort. Pediatric and adult patients in the ReNeu trial also experienced statistically significant improvements from baseline in pain, quality of life and physical function, as assessed across multiple patient-reported outcome, or PRO, tools. Mirdametinib was generally well tolerated in the ReNeu trial, with the majority of adverse events, or AEs, being Grade 1 or Grade 2. The most frequently reported AEs were rash, diarrhea and vomiting in the pediatric cohort and rash, diarrhea and nausea in the adult cohort. 25% of pediatric patients and 16% of adult patients experienced a Grade 3 or higher treatment-related AE. The FDA granted mirdametinib both Orphan Drug Designation and Fast Track Designation for NF1-PN, and the European Commission granted mirdametinib Orphan Drug Designation for NF1. In July 2023, the FDA also granted mirdametinib Rare Pediatric Disease Designation for the treatment of NF1, and as such, mirdametinib will be eligible to receive a priority review voucher, if approved. In March 2024, following the completion of our pre-NDA meeting with the FDA, we initiated a rolling NDA submission for mirdametinib in pediatric and adult patients with NF1-PN. The submission, which includes data from the ReNeu trial, is expected to be completed in the second quarter of 2024. We also expect to submit an MAA with the EMA for mirdametinib for the treatment of children and adults with NF1-PN in the European Union in the second half of 2024.

In hematologic malignancies, we are evaluating novel combination regimens of nirogacestat alongside B-cell maturation antigen, or BCMA, directed therapies for the treatment of multiple myeloma. We have entered into several, non-exclusive clinical collaboration agreements with industry partners to evaluate nirogacestat in combination with multiple different BCMA-directed therapies. Each partner is responsible for the conduct and expenses of a clinical trial to evaluate the combination of nirogacestat with its respective BCMA agent in multiple myeloma. In June 2023, updated clinical data from the GSK-sponsored Phase 1/2 trial of nirogacestat in combination with low-dose belantamab mafodotin, or belamaf, an antibody-drug conjugate targeting BCMA, and initial clinical data from the Janssen Research and Development, LLC, or Janssen, -sponsored Phase 1b clinical trial evaluating nirogacestat in combination with teclistamab, a bispecific antibody targeting BCMA and CD3, in patients with relapsed or refractory multiple myeloma were presented at the European Hematology Association 2023 Congress. The updated clinical data from the GSK-sponsored trial, as of the December 9, 2022 data cut-off date, continued to support that combining nirogacestat with a low dose of belamaf may result in comparable efficacy to a higher monotherapy belamaf dose, while substantially reducing the frequency of high-grade ocular adverse events. The initial clinical data from the Janssen-sponsored trial, as of the December 16, 2022 data cut-off date, represented the first clinical data set of nirogacestat in combination with a BCMA bispecific agent, with the results demonstrating high and deep response rates for the nirogacestat plus teclistamab combination across all dose levels assessed and an optimized safety profile with delayed administration of lower-dose nirogacestat. In July 2023, the Hellenic Society of Haematology, through a co-supported collaborative study agreement with GSK and SpringWorks, initiated a Phase 1/2 study evaluating low-dose belamaf and nirogacestat in combination with lenalidomide and dexamethasone in transplant-ineligible newly diagnosed multiple myeloma patients. In September 2023, Regeneron initiated a Phase 1b study arm evaluating nirogacestat in combination with linvoseltamab, a bispecific antibody targeting BCMA and CD3.

In genetically defined metastatic solid tumors, our current clinical-stage efforts center on the mitogen activated protein kinase, or MAPK, pathway. We are evaluating mirdametinib for the treatment of solid tumors harboring MAPK aberrations in both monotherapy and combination approaches. In collaboration with BeiGene, Ltd., or BeiGene, we are exploring the combination of mirdametinib with BeiGene’s lifirafenib (BGB-283) in NRAS mutant solid tumors. In addition, we are exploring the use of brimarafenib (BGB-3245) in a distinct set of genetically defined BRAF mutated tumors via MapKure, LLC an entity jointly owned by us and BeiGene. In February 2023, we dosed the first patient in a Phase 1/2a open-label, dose escalation and expansion trial evaluating mirdametinib in combination with brimarafenib in patients with advanced solid tumors harboring MAPK-activating mutations, and patients continue to be enrolled. In April 2023, we presented clinical data from the Phase 1a/1b trial evaluating brimarafenib in patients with advanced or refractory solid tumors harboring MAPK pathway aberrations at the American Association for Cancer Research, or AACR, Annual Meeting 2023. We also presented clinical data from the Phase 1b clinical trial evaluating mirdametinib in combination with BeiGene’s RAF dimer inhibitor, lifirafenib at the AACR Annual Meeting 2023. These clinical data showed manageable safety profiles and clinical activity in various solid tumors with MAPK pathway aberrations. Dose expansion studies are currently ongoing for each program. In the first quarter of 2024, MapKure initiated a Phase 1b combination trial of brimarafenib with panitumumab, a monoclonal antibody targeting Epidermal Growth Factor Receptor, or EGFR, in colorectal and pancreatic cancer patients with known MAPK pathway mutations; patient dosing is currently underway. In an academic-sponsored study supported by SpringWorks, mirdametinib is being evaluated for the treatment of low-grade gliomas in children and young adults.

Furthermore, we intend to continue to build our portfolio with assets that have strong biological rationales and validated mechanisms of action, such as the TEA Domain, or TEAD, inhibitor program that we in-licensed from Katholieke Universiteit Leuven and the Flanders Institute for Biotechnology. We plan to initiate a Phase 1a trial of SW-682, our TEAD inhibitor development candidate, in Hippo mutant solid tumors in the second quarter of 2024. Additionally, we are pursuing several discovery programs that represent potentially first-in-class and best-in-class product candidates designed to address tumors where no or limited treatment options exist.

In March 2024, following a review of the evolving competitive landscape for EGFR mutant lung cancers, we notified Dana-Farber Cancer Institute, or Dana-Farber, of our election to terminate our license agreement, pursuant to which we had in-licensed a portfolio of novel small molecule inhibitors of EGFR in preclinical development. The termination will be effective in September 2024. The decision also resulted in the termination of our sponsored research agreement with Stanford Medicine, or Stanford, which was intended to support lead optimization and translational biology efforts for the EGFR inhibitor portfolio. There will be no further investment in our EGFR program, and no further milestone payments or royalties to Dana-Farber are expected under the terms of the license agreement.

We continue to invest in our R&D infrastructure in a focused manner in order to support both our drug discovery capabilities and our translational medicine activities for development programs. We also plan to continue exploring shared-value partnerships to maximize the potential of our therapies to transform the lives of oncology patients.

Components of our results of operations

Revenue

In November 2023, the FDA approved OGSIVEO for the treatment of adult patients with progressing desmoid tumors who require systemic treatment. In December 2023, we began to generate revenue from sales of OGSIVEO in the United States. We record product revenue net of estimated discounts, chargebacks, rebates, product returns, and other gross-to-net revenue deductions.

Operating costs and expenses

Cost of Product Revenue

Our cost of product revenue includes the cost of goods sold, amortization expense for commercial milestones and royalty expense. Our cost of goods sold consists of raw materials, third-party manufacturing costs to manufacture the raw materials into finished product, freight and other costs associated with sales of commercial products.

Selling, general and administrative expenses

Selling, general and administrative expenses consist primarily of salaries and related costs, including equity-based compensation, for personnel in executive, finance, corporate, commercial, business development and administrative functions. Selling, general and administrative expenses also include consulting services, legal fees relating to patent and corporate matters; professional fees for accounting, auditing and tax services; insurance costs; administrative travel expenses; and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities and other operating costs.

Table of Contents

We anticipate that our selling, general and administrative expenses will increase in the future as we increase our headcount to expand operations to support the organization, including commercialization efforts.

Research and development expenses

Our research and development expenses consist of expenses incurred in connection with the development of our product candidates. These expenses include:

•employee-related expenses, which include salaries, benefits and equity-based compensation for our research and development personnel;

•fees paid to consultants for services directly related to our research and development programs;

•expenses incurred under agreements with third-party contract research organizations, investigative clinical trial sites, academic institutions and consultants that conduct research and development activities on our behalf or in collaboration with us;

•costs associated with discovery biology and medicinal chemistry efforts and with preclinical and clinical trials;

•costs associated with the manufacture of drug substance and finished drug product for preclinical testing and clinical trials;

•costs associated with technology and intellectual property licenses; and

•an allocated portion of facilities and facility-related costs, which include expenses for rent and other facility-related costs and other supplies.

External costs for research and development expenses are tracked on a program-by-program basis. Expenditures for clinical development, including upfront licensing fees and milestone payments associated with our product candidates, are charged to research and development expense as incurred. These expenses consist of expenses incurred in performing development activities, including salaries and benefits, materials and supplies, preclinical expenses, clinical trial and related clinical manufacturing expenses, depreciation of equipment, contract services and other outside expenses. Costs for certain development activities, such as manufacturing and clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using either time-based measures or data such as information provided to us by our vendors on actual activities completed or costs incurred.

We expect our research and development expenses to increase for the foreseeable future as we continue to invest in activities related to developing our product candidates and our preclinical programs, and as certain product candidates advance into later stages of development, including nirogacestat, which is being studied in ovarian granulosa cell tumors, and mirdametinib with the ReNeu trial. The process of conducting the necessary clinical trials to obtain regulatory approval is costly and time-consuming, and the successful development of our product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

Interest and other income

Interest and other income consists primarily of interest income. Interest income consists of interest earned on our cash, cash equivalents and available-for-sale marketable securities.

Equity method investment loss

The equity method investment loss represents our share of the losses from the MapKure investment, which is accounted for using the equity method of accounting.

Revenue

In November 2023, the FDA approved OGSIVEO for the treatment of adult patients with progressing desmoid tumors who require systemic treatment. For the three months ended March 31, 2024, we recorded net product revenue of $21.0 million from sales of OGSIVEO in the United States.

Selling, general and administrative expense

Selling, general and administrative expenses increased by $15.9 million to $60.1 million for the three months ended March 31, 2024 from $44.2 million for the three months ended March 31, 2023, an increase of 36%.

The increase in selling, general and administrative expenses was largely attributable to commercial activities supporting the U.S. launch of OGSIVEO. The increase in selling, general and administrative expense included a $10.1 million increase in internal costs and a $5.8 million increase in consulting and professional services. The increase in internal costs was attributable to the growth in employee costs associated with increases in the number of personnel, including an increase in equity-based compensation expense, driven by the growth of our commercial organization, which included our sales force, as well as establishing certain sales support, marketing, and commercialization functions. The increase in consulting and professional services was also primarily attributable to commercial activities supporting the OGSIVEO launch.

Research and development expenses

Research and development expenses increased by $20.1 million to $53.6 million for the three months ended March 31, 2024 from $33.5 million for the three months ended March 31, 2023, an increase of 60%.

The increase in research and development expenses was primarily attributable to an increase of $14.1 million in external costs related to drug manufacturing, clinical trials, other research, consulting and professional services, and an increase of $6.0 million in internal costs driven by the growth in employee costs associated with increases in the number of personnel, including an increase in equity-based compensation expense.

We track research and development expenses on a program-by-program basis to the extent such spend is attributable to a specific program. Our research and development expenses by program for the periods presented were as follows:

Total research and development expenses	$	53,622	$	33,524	$	20,098

Interest and other income

The increase in interest and other income was driven by an increase in interest income, net, for the three months ended March 31, 2024 as compared to the three months ended March 31, 2023. This increase was attributable to higher market yield and increased cash from financing activities during the year ended December 31, 2023.

Liquidity and Capital Resources

Sources of Liquidity

We have incurred operating losses and experienced negative operating cash flows since our inception and anticipate that we will continue to incur losses for at least the foreseeable future. Our net loss was $87.4 million and $73.4 million for the three months ended March 31, 2024 and March 31, 2023, respectively. We had an accumulated deficit of $982.4 million and $895.0 million as of March 31, 2024 and December 31, 2023, respectively. Based on our cash, cash equivalents and marketable securities balances as of March 31, 2024, management estimates that our liquidity position will enable us to meet operating expenses through at least twelve months after the date that this Quarterly Report is filed. Our marketable securities consist of high-quality, highly liquid available-for-sale debt securities including corporate debt securities, U.S. government securities, and commercial paper.

Cash Flows

The following table provides information regarding our cash flows for the three months ended March 31, 2024 and March 31, 2023:


	Three Months Ended March 31,
(in thousands)	2024		2023
Net cash used in operating activities	$	(78,930)	$	(61,818)
Net cash provided by investing activities	21,463		98,604
Net cash used in financing activities	(552)		(1,848)
Net (decrease) increase in cash and cash equivalents	(58,019)		34,938
Cash and cash equivalents including Restricted cash, beginning of period	176,666		68,068
Cash and cash equivalents including Restricted cash, end of period	$	118,647	$	103,006

Net Cash Used in Operating Activities

Net cash used in operating activities was $78.9 million for the three months ended March 31, 2024, which was driven by a net loss of $87.4 million and a net decrease from changes in operating assets and liabilities of $24.2 million, partially offset by equity-based compensation expense of $30.5 million. Net cash used in operating activities was $61.8 million for the three months ended March 31, 2023, driven by a net loss of $73.4 million, and a net decrease from changes in operating assets and liabilities of $13.6 million, partially offset by equity-based compensation expense of $23.4 million.

Net Cash Provided by Investing Activities

Table of Contents

Net cash provided by investing activities for the three months ended March 31, 2024 was driven by the sale and maturities of available-for-sale debt securities of $103.9 million, partially offset by purchases of available-for-sale debt securities of $73.6 million and our investment in MapKure of $8.2 million. Net cash provided by investing activities for the three months ended March 31, 2023 was driven by the sale and maturities of available-for-sale debt securities of $172.5 million, partially offset by purchases of available-for-sale debt securities of $68.1 million, capital expenditures of $3.0 million and our investment in MapKure of $2.8 million.

Net Cash Used in Financing Activities

Net cash used in financing activities for the three months ended March 31, 2024 and the three months ended March 31, 2023 consisted of stock repurchased to satisfy employee tax withholding obligations upon vesting of restricted stock awards, partially offset by proceeds from stock option exercises.

Funding Requirements

Our primary use of cash is to fund operating expenses, including our research and development programs, as well as our commercialization activities and corporate operations. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable, accrued expenses and prepaid expenses.

Our future funding requirements will depend on many factors, including the following:

•the initiation, progress, timing, costs and results of preclinical studies and clinical trials for our product candidates;

•the cost of establishing sales, marketing and distribution capabilities for any product candidates for which we may receive regulatory approval in regions where we choose to commercialize our products on our own;

•the degree of commercial success achieved following the successful completion of development and regulatory approval activities for a product candidate;

•the clinical development plans we establish for our product candidates;

•the number and characteristics of product candidates that we develop;

•the outcome, timing and cost of meeting regulatory requirements established by the FDA, the EMA and other comparable foreign regulatory authorities;

•the terms of our existing and any future license or collaboration agreements we may choose to enter into, including the amount of upfront, milestone and royalty obligations;

•the other costs associated with in-licensing new technologies, such as any increased costs of research and development and personnel;

•the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;

•the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us or our product candidates;

•the effect of competing technological and market developments; and

•the cost and timing of completion of commercial-scale outsourced manufacturing activities.

We may need additional funds to meet operational needs and capital requirements for clinical trials, other research and development expenditures, commercial activities and business development efforts. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical studies.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, current ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect rights of common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, limit, reduce or terminate our research, product development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Effects of Inflation

Table of Contents

Although our operations are influenced by general economic conditions, we do not believe that inflation has had a material impact on our business, financial condition, or operating results during the periods presented.

Contractual Obligations

During the three months ended March 31, 2024, there were no material changes to our contractual obligations and commitments from those described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations” in Part II Item 6. of our 2023 Form 10-K.

Critical Accounting Policies and Use of Estimates

This discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts and the related disclosures in the financial statements and accompanying notes. These accounting policies involve critical accounting estimates because they are particularly dependent on estimates and assumptions made by management about matters that are uncertain at the time the accounting estimates are made. We base our estimates on historical experience, known trends and other market-specific or relevant factors that we believe to be reasonable under the circumstances, the results of which form the basis of making judgments; however, because future events and their effects cannot be determined with certainty, actual results may differ from those estimates, judgments or assumptions, and such differences could be material. On an ongoing basis, we evaluate our estimates, judgments and assumptions, and adjust those estimates, judgments and assumptions when facts or circumstances change. Changes in estimates are recorded in the period in which they become known. Although we believe that these estimates are reasonable, actual results could differ.

We describe our significant accounting policies in Note 3, Summary of Significant Accounting Policies, of the notes to the financial statements included in our 2023 Form 10-K. We discuss our critical accounting estimates in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, in our 2023 Form 10-K. There have been no changes in our significant accounting policies or critical accounting estimates during the three months ended March 31, 2024.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

There were no material changes to our market risks from those described in Part II Item 7A. Quantitative and qualitative disclosures about market risk in our 2023 Form 10-K.

Item 4. Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, or the Exchange Act), as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective at a reasonable assurance level in ensuring that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms; and (ii) accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely discussions regarding required disclosure. We believe that a control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. Other Information

Item 1. Legal Proceedings

As of the date of this Quarterly Report on Form 10-Q, we are not a party to any material legal proceedings. In the future, we may be involved in various claims and legal proceedings relating to claims arising out of our operations. The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be disposed of unfavorably to us, which could materially affect our financial condition or results of operations.

Item 1A. Risk Factors

In addition to the other information contained elsewhere in this report, you should carefully consider the risks and uncertainties described in our “Part I, Item 1A—Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2023, or 2023 Form 10-K, filed with the Securities and Exchange Commission, or SEC, on February 27, 2024, which could materially and adversely affect our business, prospects, financial condition and results of operations. New risk factors can emerge from time to time, and it is not possible to predict the impact that any factor or combination of factors may have on our business, prospects, financial condition and results of operations. The risk factors disclosure in our 2023 Form 10-K is qualified by the information that is described in this Quarterly Report on Form 10-Q. The risks described in our 2023 Form 10-K are not our only risks. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results. There have been no material changes in our risk factors previously disclosed in our 2023 Form 10-K.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

None.

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures
