ARVINAS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements (unaudited)

1. Nature of Business and Basis of Presentation

Arvinas, Inc. and its subsidiaries (“Arvinas” or the "Company”) is a clinical-stage biotechnology company dedicated to improving the lives of patients suffering from debilitating and life-threatening diseases.

The accompanying unaudited condensed consolidated financial statements include the accounts of Arvinas, Inc. and its subsidiaries. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X under the Securities Exchange Act of 1934, as amended (“Exchange Act”). Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to U.S. Securities and Exchange Commission (“SEC”) rules. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation have been included. The condensed consolidated balance sheet as of December 31, 2024 has been derived from the Company's audited consolidated financial statements as of that date. The financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2024, forming part of Arvinas’ 2024 Annual Report on Form 10-K filed with the SEC on February 11, 2025.

The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amount of assets, liabilities, revenue and expenses. These estimates include assumptions and judgments based on historical experience, current conditions, future expectations and other factors the Company considers reasonable. These estimates are reviewed on an ongoing basis and revised as necessary. Actual results could differ from these estimates.

Risks and Uncertainties

The Company is subject to a number of risks similar to other biotechnology companies in a similar stage, including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical testing or clinical trials, the need to obtain marketing approval for its product candidates, competitors developing new technological innovations, and the need to successfully commercialize and gain market acceptance of the Company’s products and to protect its proprietary technology. If the Company does not successfully obtain regulatory approval of its product candidates, it will be unable to generate revenue from product sales or achieve profitability.

To date, the Company has not generated any revenue from product sales and expects to incur additional operating losses and negative operating cash flows for the foreseeable future. The Company has financed its operations primarily through sales of assets and equity interests, proceeds from collaborations and a licensing arrangement, grant funding and debt financing. The Company had cash, cash equivalents and marketable securities of approximately $1.0 billion as of March 31, 2025.

2. Summary of Accounting Pronouncements and Significant Accounting Policies

Accounting Pronouncements

Recently Adopted Accounting Pronouncements

There have been no recently adopted accounting pronouncements that have had a material impact on the Company's unaudited condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) - In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, "Disaggregation of Income Statement Expenses," which requires

Table of Contents

disclosures of certain disaggregated income statement expense captions into specified categories within the footnotes to the financial statements. The requirements of the ASU are effective for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The requirements will be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact ASU No. 2024-03 will have on its condensed consolidated financial statements.

Income Taxes (Topic 740) - In December 2023, the FASB issued ASU No. 2023-09, "Improvements to Income Tax Disclosures," which requires enhanced income tax disclosures, including specific categories and disaggregation of information in the effective tax rate reconciliation, disaggregated information related to income taxes paid, income or loss from continuing operations before income tax expense or benefit and income tax expense or benefit from continuing operations. The requirements of the ASU are effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact ASU No. 2023-09 will have on its condensed consolidated financial statements.

Significant Accounting Policies

There were no changes to the Company’s significant accounting policies during the three months ended March 31, 2025.

Cash, Cash Equivalents and Restricted Cash

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the condensed consolidated balance sheets to the total amounts shown in the condensed consolidated statements of cash flows for the three months ended March 31, 2025 and 2024:


(dollars in millions)	March 31, 2025		March 31, 2024
Cash and cash equivalents	$	81.0	$	88.0
Restricted cash	—		5.5
Cash, cash equivalents and restricted cash	$	81.0	$	93.5

Restricted cash represents a letter of credit collateralized by a certificate of deposit in the same amount which was canceled in connection with a lease termination agreement the Company entered into with 101 College Street LLC in August 2024.

3. Research Collaboration and License Agreements

Vepdegestrant (ARV-471) Collaboration Agreement

In July 2021, the Company entered into a Collaboration Agreement with Pfizer Inc. (“Pfizer”) (the “Vepdegestrant (ARV-471) Collaboration Agreement”) pursuant to which the Company granted Pfizer worldwide co-exclusive rights to develop and commercialize products containing the Company’s proprietary compound vepdegestrant (the “Licensed Products”). Under the Vepdegestrant (ARV-471) Collaboration Agreement, the Company received an upfront, non-refundable payment of $650.0 million. In addition, the Company is eligible to receive up to an additional $1.4 billion in contingent payments based on specific regulatory and sales-based milestones for the Licensed Products. Of the total contingent payments, $400.0 million in regulatory milestones are related to marketing approvals and $1.0 billion are related to sales-based milestones. There were no regulatory or sales-based milestone payments received through March 31, 2025.

The Company and Pfizer share equally all development costs, including costs of conducting clinical trials, for the Licensed Products, subject to certain exceptions. Except for certain regions described below, the parties will also share equally all profits and losses in commercialization and medical affairs activities for the Licensed Products in all other countries, subject to certain exceptions.

The Company will be the marketing authorization holder in the United States and, subject to marketing approval, book sales in the United States, while Pfizer will hold marketing authorizations outside the United States. The parties will determine which, if any, regions within the world will be solely commercialized by one

Table of Contents

party, and in such region the parties will adjust their share of profits and losses for the Licensed Products based on the role each party will be performing.

As a direct result of the Company’s entry into the Vepdegestrant (ARV-471) Collaboration Agreement, the Company incurred direct and incremental costs to obtain the contract, paid to a financial advisor, totaling $12.9 million. In accordance with Accounting Standards Codification ("ASC") 340, Other Assets and Deferred Costs, the Company recognized an asset of $12.9 million in collaboration contract asset and other assets in the condensed consolidated balance sheet at inception of the Vepdegestrant (ARV-471) Collaboration Agreement, which is being amortized as general and administrative expense over the total estimated period of performance under the Vepdegestrant (ARV-471) Collaboration Agreement.

Pfizer Research Collaboration Agreement

In December 2017, the Company entered into a Research Collaboration and License Agreement with Pfizer (the “Pfizer Research Collaboration Agreement”). Under the terms of the Pfizer Research Collaboration Agreement, the Company received an upfront, non-refundable payment and certain additional payments totaling $28.0 million in 2018 in exchange for use of the Company’s technology license and to fund Pfizer-related research as defined within the Pfizer Research Collaboration Agreement. These payments are being recognized over the total estimated period of performance. As of March 31, 2025, there remains a single target under the Pfizer Research Collaboration Agreement, and, in accordance with the terms of such Agreement, the Company is eligible to receive up to an additional $3.8 million in non-refundable option payments if Pfizer exercises its option for such target protein.

The Company is also entitled to receive up to $225.0 million in development milestone payments and up to $550.0 million in sales-based milestone payments for all designated target proteins under the Pfizer Research Collaboration Agreement, as well as tiered royalties based on sales. There were no sales-based milestone payments or royalties received through March 31, 2025.

Novartis License and Asset Agreements

In April 2024, the Company entered into a transaction (the "Novartis Transaction"), including both a license agreement (the "Novartis License Agreement") and an asset purchase agreement (the "Novartis Asset Agreement") with Novartis Pharma AG ("Novartis") for the worldwide development, manufacture and commercialization of luxdegalutamide (ARV-766), the Company's second generation PROTAC androgen receptor (AR) degrader for patients with prostate cancer and for the sale of the Company's preclinical AR-V7 program. Under the terms of the agreements, Novartis is responsible for worldwide clinical development and commercialization of luxdegalutamide (ARV-766) and has all research, development, manufacturing, and commercialization rights with respect to the Company’s PROTAC protein degrader targeting AR-V7, a splice variant of the AR.

In May 2024, the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, expired with respect to the Novartis Transaction (the “HSR Termination”). As a result of the HSR Termination and satisfaction of other closing conditions, Novartis paid to the Company a one-time, upfront payment in the aggregate amount of $150.0 million in accordance with the terms of the Novartis License Agreement and the Novartis Asset Agreement. Under the terms of the Novartis License Agreement, the Company is eligible to receive up to an additional $1.01 billion as contingent payments based on specified development, regulatory and commercial milestones for luxdegalutamide (ARV-766) being met, as well as tiered royalties based on worldwide net sales of luxdegalutamide (ARV-766), subject to reduction under certain circumstances as provided in the Novartis License Agreement. There were no development, regulatory or commercial milestone payments, or sales-based royalties received through March 31, 2025.

The Novartis License Agreement will continue on a country-by-country basis (or, in certain cases, a region-by-region basis) until the expiration of the applicable royalty term for such country (or region, as applicable). The Novartis License Agreement contains customary termination provisions, including that either party may terminate the Novartis License Agreement (a) upon the material breach of the other party or (b) in the event the other party experiences an insolvency event. Additionally, Novartis may terminate the Novartis License Agreement for convenience or upon a safety or regulatory issue.

The Company determined that the Novartis License Agreement and the Novartis Asset Agreement entered into with Novartis concurrently should be accounted for as a combined contract in accordance with ASC

Table of Contents

606, Revenue from Contracts with Customers. The Company determined the fair value of the assets sold under the Novartis Asset Agreement to be $20.0 million, which was recognized at the time of sale as revenue, and the fair value of the Novartis License Agreement to be $130.0 million, which was recognized as revenue over the total estimated period of performance during the technology transfer period, as defined in the agreement, based on the cost incurred input method. Under the Novartis License Agreement, Novartis also reimbursed the Company for development costs incurred during the technology transfer period, which was recognized as revenue as costs were incurred. As of December 31, 2024, the technology transfer period ended as the Company completed the transition of its ongoing and planned clinical trials of luxdegalutamide (ARV-766) to Novartis.

As a direct result of the Company’s entry into the Novartis Transaction, the Company incurred direct and incremental costs to obtain the contract, paid to a financial advisor, totaling $3.0 million. In accordance with ASC 340, Other Assets and Deferred Costs, the Company recognized an asset of $3.0 million in collaboration contract asset and other assets in the condensed consolidated balance sheet at inception of the Novartis License Agreement and the Novartis Asset Agreement, which was amortized as general and administrative expense over the total estimated period of performance under the Novartis License Agreement and the Novartis Asset Agreement.

Bayer Collaboration Agreement

In June 2019, the Company and Bayer AG entered into a Collaboration and License Agreement (the “Bayer Collaboration Agreement”) setting forth the Company’s collaboration with Bayer AG to identify or optimize proteolysis targeting chimeras ("PROTAC targeted protein degraders") that mediate the degradation of target proteins. Under the terms of the Bayer Collaboration Agreement, the Company received an upfront, non-refundable payment of $17.5 million in exchange for the use of the Company’s technology license. The Company also received an additional $12.0 million from Bayer AG from inception through 2023. These payments were recognized over the total estimated period of performance.

The Company was also eligible to receive up to $197.5 million in development milestone payments and up to $490.0 million in sales-based milestone payments for all designated target proteins. In addition, the Company was eligible to receive, on net sales of PROTAC targeted protein degrader-related products, mid-single digit to low-double digit tiered royalties, which were subject to reductions.

During the three months ended March 31, 2025, the Company updated its estimate to satisfy the performance obligations under the Vepdegestrant (ARV-471) Collaboration Agreement due to the removal of the first-line Phase 3 combination trial with Pfizer’s novel investigational CDK4 inhibitor, atirmociclib, and the removal of the second-line Phase 3 combination trial with a CDK4/6 inhibitor from the development plan. The change in accounting estimate resulted in an increase in revenue of $150.2 million, an increase in operating expenses of $2.6 million, an increase in net income of $147.6 million, and an increase in basic and diluted earnings per share of $2.04 and $2.03, respectively, for the three months ended March 31, 2025.

During the three months ended March 31, 2025, the Company also changed its estimate of the duration of the performance period under the Pfizer Research Collaboration Agreement as a result of updated research timelines. The change in accounting estimate resulted in a decrease in revenue and net income of $2.5 million, respectively, and a decrease in basic and diluted earnings per share of $0.03 for the three months ended March 31, 2025. The reversed revenue will continue to be recognized in future periods as the Company continues to advance on the performance obligation under the updated collaboration timeline.

During the three months ended March 31, 2024, no changes in accounting estimates related to the Company's collaborations were recorded.

The aggregate amount of the transaction price allocated to performance obligations that were unsatisfied as of March 31, 2025 totaled $259.4 million, which is expected to be recognized in the following periods:

Government securities	Level 2	3.5		—		—		3.5
Total		$	937.9	$	1.7	$	(0.7)	$	938.9

The Company generally does not intend to sell any investments prior to recovery of their amortized cost basis for any investment in an unrealized loss position. As such, the Company has classified these losses as temporary in nature.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities approximate their fair values due to the short-term nature of these assets and liabilities.

5. Property, Equipment and Leasehold Improvements

Property, equipment and leasehold improvements consist of the following:

During the three months ended March 31, 2025 and 2024, the Company recognized depreciation and amortization expense of $0.7 million and $1.2 million, respectively.

6. Right-of-Use Assets and Liabilities

Operating lease liabilities and their corresponding right-of-use ("ROU") assets are recorded based on the present value of lease payments over the expected remaining lease term. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rate, which reflects the fixed rate at which it could borrow on a collateralized basis the amount of the lease payments in the same currency, for a similar term, in a similar economic environment. The Company's weighted average incremental borrowing rate at March 31, 2025 totaled 6.9%. Lease expense is recognized on a straight-line basis over the lease term.

Stock-based Compensation

2018 Employee Stock Purchase Plan

In September 2018, the Company adopted the 2018 Employee Stock Purchase Plan (the “2018 ESPP”), with the first offering period under the 2018 ESPP commencing on January 1, 2020, by initially providing participating employees with the opportunity to purchase an aggregate of 311,850 shares of the Company’s common stock. The number of shares of the Company’s common stock reserved for issuance under the 2018 ESPP increased, pursuant to the terms of the 2018 ESPP, by additional shares equal to 1% of the Company’s then-outstanding common stock, effective as of January 1 of each year. As of March 31, 2025, 3,687,437 shares remained available for purchase. During the three months ended March 31, 2025 and 2024, the Company issued zero and 34,515 shares of common stock, respectively, under the 2018 ESPP.

2018 Stock Incentive Plan

In September 2018, the Company’s board of directors adopted, and the Company’s stockholders approved, the 2018 Stock Incentive Plan (the “2018 Plan”), which became effective upon the effectiveness of the registration statement on Form S-1 for the Company’s initial public offering. The number of shares of common stock initially available for issuance under the 2018 Plan equaled the sum of (1) 4,067,007 shares of common stock; plus (2) the number of shares of common stock (up to 1,277,181 shares) issued in respect of incentive units granted under the Fourth Amendment to the Company’s Incentive Share Plan, which was terminated in September 2018, that were subject to vesting immediately prior to the effectiveness of the registration statement that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right; plus (3) an annual increase on the first day of each fiscal year beginning with the fiscal year ended December 31, 2019 and continuing to, and including, the fiscal year ending December 31, 2028, equal to the lesser of 4,989,593 shares of the Company’s common stock, 4% of the number of shares of the Company’s common stock outstanding on the first day of the year or an amount determined by the Company’s board of directors. As of March 31, 2025, 3,327,876 shares remained available for issuance under the 2018 Plan. Shares of common stock subject to outstanding equity awards that expire or are terminated, surrendered or canceled without having been fully exercised or are forfeited in whole or in part are available for future grants of awards.

Compensation Expense

During the three months ended March 31, 2025 and 2024, the Company recognized compensation expense of $15.0 million and $18.6 million, respectively, related to the issuance of incentive awards, including $0.2 million related to the 2018 ESPP in each period presented.

As of March 31, 2025, there was $73.6 million of total unrecognized compensation expense that is expected to be amortized over a weighted average period of approximately 1.7 years.

Stock Options

The fair value of the stock options granted during the three months ended March 31, 2025 and 2024 was determined using the Black-Scholes option pricing model with the following assumptions:


	March 31, 2025		March 31, 2024
Expected volatility (1)	72.1 - 72.2%		75.1 - 75.6%
Expected term (years) (2)	5.5 - 5.6		5.4 - 5.5
Risk free interest rate (3)	4.0% - 4.4%		3.9% - 4.3%
Expected dividend yield	0	%	0	%
Exercise price	$16.23 - $17.70		$38.10 - $47.00

(1) Expected volatility is calculated by utilizing the Company's historical volatility of its stock price over a period equal to the expected term.

(2) Expected term is calculated based on the Company's historical experience.

(3) Risk free interest rate is based on an interpolation of U.S. Treasury rates to reflect the expected term at the date of grant.

Restricted Stock Units ("RSUs")

A summary of RSU activity during the three months ended March 31, 2025 is presented below. Included in the table are RSUs granted to employees and directors under the 2018 Plan, as well as RSUs representing 170,365 shares of common stock granted to certain employees pursuant to the Nasdaq inducement grant exception in accordance with Nasdaq Listing Rule 5635(c)(4).


	Shares	Weighted Average Grant Date Fair Value Per Share
Unvested RSUs as of December 31, 2024	2,311,291	$	42.25
Granted	2,229,467	$	17.66

Forfeited	(146,054)	$	44.92
Unvested RSUs as of March 31, 2025	3,589,126	$	26.17

The weighted-average grant date fair value per share of RSUs granted during the three months ended March 31, 2025 and 2024 was $17.66 and $46.55, respectively. The total intrinsic value of RSUs released during the three months ended March 31, 2025 and 2024 was $14.1 million and $9.4 million, respectively. The total fair value of RSUs vested during the three months ended March 31, 2025 and 2024 was $36.5 million and $8.1 million, respectively.

10. Income Taxes

For the three months ended March 31, 2025, the Company recognized income tax expense of $0.2 million, resulting in an effective tax rate of 0.2%, as compared to income tax expense of $0.1 million, resulting in an effective tax rate of (0.2)%, in the same period for 2024. The primary reconciling items between the federal statutory rate of 21.0% for the three months ended March 31, 2025 and the Company’s overall effective tax rate of 0.2% was the effect of equity compensation and the valuation allowance recorded against the full amount of its net deferred tax assets. The primary reconciling items between the federal statutory rate of 21.0% for the

Table of Contents

three months ended March 31, 2024 and the Company’s overall effective tax rate of (0.2)% was the effect of equity compensation and the valuation allowance recorded against the full amount of its net deferred tax assets.

A valuation allowance is established when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company continues to establish a valuation allowance against the full amount of its net deferred tax assets since it is more likely than not that benefits will not be realized, including those benefits created in the current year. This assessment is based on the Company's historical cumulative losses, which provide strong objective evidence that cannot be overcome with projections of income, as well as the fact the Company expects continuing losses in the future.

11. Earnings (Loss) Per Common Share

Basic and diluted earnings (loss) per common share was calculated as follows:


	For the Three Months Ended March 31,
(dollars and shares in millions, except per share amounts)	2025		2024
Net income (loss)	$	82.9	$	(69.4)

Basic weighted average common shares outstanding	72.5		71.7
Denominator adjustments for diluted EPS:
Number of stock options and RSUs	0.2		—
Denominator adjustments for diluted EPS:	0.2		—
Diluted weighted average common shares outstanding	72.7		71.7

Earnings (loss) per common share
Basic	$	1.14	$	(0.97)
Diluted	$	1.14	$	(0.97)

The weighted average number of common shares included in the computation of basic and diluted net loss per common share for the three months ended March 31, 2024 gives effect to pre-funded warrants issued in November 2023 which allowed holders to acquire up 3,422,380 shares of common stock at a nominal exercise price of $0.001 per share and were classified as equity. The shares underlying the pre-funded warrants were exercisable for little or no consideration and therefore the underlying shares were considered outstanding at the issuance of the pre-funded warrants for purposes of calculating the weighted average number of common shares outstanding in basic and diluted net loss per share for common share. As of March 31, 2025, all outstanding pre-funded warrants were cashless exercised for no consideration and the Company issued 3,422,186 shares of common stock to the holders.

The Company reported a net loss for the three months ended March 31, 2024 and therefore excluded all stock options and RSUs from the calculation of diluted net loss per common share as their inclusion would have had an anti-dilutive effect, as summarized below:


									For the Three Months Ended March 31,
									2024
Stock options									8.6

RSUs									2.5
									11.1

12. Equity Method Investments

In July 2019, the Company and Bayer CropScience LP (“Bayer LP”) formed Oerth Bio LLC ("Oerth Bio"), a joint venture to research, develop and commercialize PROTAC targeted protein degraders for applications in the field of agriculture. The Company and Bayer LP each held an initial ownership interest in Oerth Bio of 50%. A 15% ownership interest of Oerth Bio was reserved for the future grants of incentive units to employees and service providers and, as a result, the Company's ownership interest totaled 43.5% and 44.6% as of March 31, 2025 and 2024, respectively, as a result of vested incentive units.

Net income (loss) of Oerth Bio for the three months ended March 31, 2025 and 2024 totaled $0.6 million and $(0.7) million, respectively.

As of March 31, 2025 and 2024, the Company’s carrying value of the investment was zero.

The Company also provides Oerth Bio with compensated research, development and administrative services through a separate agreement. The services rendered by the Company during the three months ended March 31, 2025 and 2024 were immaterial.

13. Commitments and Contingencies

From time to time, the Company may be subject to legal proceedings, claims and disputes that arise in the ordinary course of business. The Company accrues a liability for such matters when it is probable that future expenditures will be made and that such expenditures can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount, which could differ materially. Legal fees and other costs associated with such actions are expensed as incurred. The Company's accrual for such matters totaled $5.0 million and $15.2 million as of March 31, 2025 and 2024, respectively, related to the Amended License Agreement with Yale University ("Yale"), as further described below.

Clinical and Preclinical Development and Licensing Arrangements

From time to time, the Company enters into contracts in the normal course of business with various third parties who support its clinical trials, preclinical research studies and other services related to its development activities. The scope of the services under these agreements can generally be modified at any time, and the agreement can be terminated by either party after a period of notice and receipt of written notice.

In addition, under licensing and related arrangements to which the Company is a party, the Company may be obligated to make milestone payments to third parties. The payment obligations under these arrangements are contingent upon future events, such as achievement of specified milestones or generation of product sales, and the amount, timing and likelihood of such payments are not known.

Yale University License Agreement

In June 2024, the Company entered into an Amended and Restated License Agreement (the “Amended License Agreement”) with Yale pursuant to which the parties amended and restated the license agreement dated July 5, 2013, as amended to date (the "Original Agreement"). In connection with the signing of the Amended License Agreement, the Company made a payment of $14.95 million to Yale, comprising both an upfront payment connected to the Amended License Agreement and an amount related to the collaboration income under the Novartis License Agreement and Novartis Asset Agreement (see Note 3, Research Collaboration and License Agreements, for a description of the agreements). The Company will make another $5.0 million payment on the first anniversary of signing. Thereafter, the Company will also pay to Yale (1) up to $15.0 million if it secures approval of the first and second royalty products (as defined in the Amended License Agreement), (2) a low single digit percentage royalty on certain, more narrowly defined “collaboration products,” and (3) a lower single digit royalty on its aggregate worldwide net sales of certain newly defined “meaningfully involved products.”

The Company’s obligations under the Original Agreement to pay Yale minimum annual royalties and certain other annual fees have been eliminated and Yale has agreed to release all claims arising previously under the Original Agreement. Other provisions of the Original Agreement remain materially unchanged under the Amended License Agreement, including the requirement to pay to Yale a minimum license maintenance

royalty totaling $0.1 million per year until the first sale to a third party of any licensed product, followed by success-based milestones for the first two licensed products for the development of the protein degradation technologies totaling approximately $3.0 million for the first licensed product and approximately $1.5 million for the second licensed product, certain of which milestones have already been satisfied, and low single-digit royalties on aggregate worldwide net sales of certain licensed products, which may be subject to reductions, and subject to minimum royalty payments that range from $0.2 million to $0.5 million.

14. Segment Information

The Company's operations are organized into one operating and reportable segment focused on the discovery, development and commercialization of therapies that degrade disease-causing proteins. The segment develops protein degradation therapies designed to harness the body's natural protein disposal system to selectively and efficiently degrade and remove disease-causing protein through the Company's PROTAC (PROteolysis TArgeting Chimera) protein degrader platform. The Company is progressing multiple product candidates through clinical development programs, including vepdegestrant, targeting the estrogen receptor for patients with locally advanced or metastatic ER+/HER2- breast cancer; ARV-393, targeting BCL6 for relapsed/refractory non-Hodgkin Lymphoma; and ARV-102, targeting LRRK2 for neurodegenerative disorders. The Company's tangible assets are held in the United States and all of the Company's revenue has been generated in the United States. The Company manages all business activities on a consolidated basis. The Company's chief operating decision maker is the Chief Executive Officer.

The operating segment's revenue is primarily generated through research collaborations and licensing arrangements with pharmaceutical partners. The terms of these agreements contain multiple goods and services which may include (i) licenses, (ii) research and development activities, and (iii) participation in joint research and development steering committees. The terms of these agreements may include non-refundable, upfront license or option fees, payments for research and development activities, payments upon the achievement of certain milestones and royalty payments based on product sales derived from the collaboration. Revenue is recognized ratably over the Company’s expected performance period under each respective arrangement. The Company has also generated revenue through the sale of assets based on fair value. The Company does not have intra-entity sales or transfers.

The accounting policies of the operating segment are the same as those described in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 and in Note 2, Summary of Accounting Pronouncements and Significant Accounting Policies. The chief operating decision maker evaluates the performance of the operating segment and allocates resources based on net income/ loss that also is reported on the consolidated income statement as net income (loss). The measure of the operating segment assets is reported on the consolidated balance sheet as total assets.

The chief operating decision maker uses net loss to monitor budget versus actual results and to analyze cash flows in assessing performance of the segment and allocating resources.

15. Subsequent Events

Reduction in Force

On April 30, 2025, the Company's management, pursuant to authority delegated by the Board of Directors of the Company, committed the Company to and approved a reduction of the Company’s workforce by approximately 33% across all areas of the Company, as part of the Company’s decision to streamline operations across the organization and enable the efficient progression of the Company’s portfolio.

The Company expects the workforce reduction will be substantially completed by the end of the second quarter of 2025. The Company estimates that it will incur approximately $10.0 million in costs in connection with the workforce reduction, which consist of severance and other one-time employee termination benefit expenses which the Company expects to recognize primarily in the second quarter of 2025. The estimates of costs that the Company expects to incur, and the timing thereof, are subject to a number of assumptions and actual results may differ. The Company may also incur other charges or cash expenditures not currently contemplated due to events that may occur as a result of, or associated with, the workforce reduction.

Business Overview

Our Business

We are a clinical-stage biotechnology company dedicated to improving the lives of patients suffering from debilitating and life-threatening diseases. Through our PROteolysis TArgeting Chimera, or PROTAC, degrader platform, we are pioneering the development of protein degradation therapies designed to harness the body’s own natural protein disposal system to selectively and efficiently degrade and remove disease-causing proteins. We believe that our targeted protein degradation approach is a therapeutic modality that may provide distinct advantages over existing modalities, including traditional small molecule therapies and gene-based medicines. We are currently progressing multiple product candidates through clinical development programs, including vepdegestrant, targeting the estrogen receptor, or ER, for the treatment of locally advanced or metastatic ER positive / human epidermal growth factor receptor 2, or HER2, negative, or ER+/HER2-, breast cancer; ARV-393, targeting the B-cell lymphoma 6, or BCL6 protein for the treatment of relapsed/refractory non-Hodgkin Lymphoma, or NHL; and ARV-102, targeting the leucine-rich repeat kinase 2, or LRRK2, protein for the treatment of neurodegenerative disorders. We also have programs in preclinical development, and plan to advance ARV-806 into a first-in-human Phase 1 clinical trial in patients with solid tumors harboring Kirsten rat sarcoma, or KRAS, G12D mutations.

Our pipeline, which includes an overview of our pivotal trial for vepdegestrant, as well as our clinical and preclinical programs, is summarized below.

Oncology Programs: Vepdegestrant and ARV-393

Estrogen Receptor Program: Vepdegestrant

Vepdegestrant is an investigational orally bioavailable PROTAC protein degrader designed to specifically target and degrade the ER for the treatment of locally advanced or metastatic ER+/HER2- breast cancer. We are co-developing vepdegestrant with Pfizer, pursuant to a collaboration agreement that we and Pfizer entered into in July 2021. We granted Pfizer worldwide co-exclusive rights to develop and commercialize vepdegestrant.

In preclinical studies, vepdegestrant demonstrated near-complete ER degradation in tumor cells, induced robust tumor shrinkage when dosed as a single agent in multiple ER-driven xenograft models and showed superior anti-tumor activity when compared to a standard of care agent, fulvestrant, both as a single agent and in combination with a cyclin-dependent kinase, or CDK, 4/6 inhibitor.

We, along with Pfizer, have several ongoing clinical trials of vepdegestrant, and Pfizer has a clinical trial which it plans to add a vepdegestrant combination cohort to, which are summarized below.

•Vepdegestrant is currently under investigation; its safety and effectiveness for these investigational uses have not been established.

Clinical trials fully enrolled except for ribociclib combination trial.

In the first quarter of 2025, we, along with Pfizer, announced positive topline results from the Phase 3 VERITAC-2 clinical trial in the estrogen receptor 1-mutant, or ESR1m, population. We and Pfizer plan to present detailed results from the VERITAC-2 Phase 3 clinical trial in a late-breaker oral presentation at the 2025 American Society of Clinical Oncology Annual Meeting in the second quarter of 2025, share these data with global regulatory authorities to potentially support regulatory filings also in the second quarter of 2025, and

Table of Contents

submit a new drug application to the U.S. Food and Drug Administration for potential approval in the second half of 2025.

The Phase 3 VERITAC-2 clinical trial is a global randomized study evaluating the efficacy and safety of vepdegestrant as a monotherapy compared to fulvestrant in patients with ER+/HER2- advanced or metastatic breast cancer. The trial enrolled 624 patients at sites in 26 countries who had previously received treatment with a CDK4/6 inhibitor plus endocrine therapy. Patients were randomized to receive either vepdegestrant once daily, orally on a 28-day continuous dosing schedule, or fulvestrant, administered intramuscularly on Days 1 and 15 of Cycle 1 and then on Day 1 of each 28-day cycle starting from Day 1 of Cycle 2. The primary endpoint was progression-free survival, or PFS, by blinded independent central review among patients with ESR1m and among all patients, also known as the intent to treat, or ITT, population.

The Phase 3 VERITAC-2 trial met its primary endpoint in the ESR1m population, demonstrating a statistically significant and clinically meaningful improvement in PFS compared to fulvestrant. The results exceeded the pre-specified target hazard ratio of 0.60 in the ESR1m population. The trial did not reach statistical significance in improvement in PFS in the ITT population.

Overall survival was not mature at the time of the analysis of data, with less than a quarter of the required number of events having occurred. The trial will continue to assess overall survival as a key secondary endpoint. In the trial, vepdegestrant was generally well tolerated and its safety profile was consistent with what has been observed in previous studies.

In the second quarter of 2025, we announced that we and Pfizer removed two planned Phase 3 combination trials of vepdegestrant from the agreed-upon joint development plan: a first-line Phase 3 combination trial with Pfizer’s novel investigational CDK4 inhibitor, atirmociclib, and a second-line Phase 3 combination trial with a CDK4/6 inhibitor.

Additionally, in the second quarter of 2025, we announced that Pfizer plans to add a vepdegestrant combination cohort to its ongoing Phase 1 clinical trial evaluating Pfizer’s investigational KAT6 inhibitor in combination with endocrine therapies following CDK4/6 inhibitor treatment. This clinical trial is being operationalized and funded solely by Pfizer.

Hematology Program: ARV-393

ARV-393 is an investigational, orally bioavailable PROTAC designed to degrade BCL6, a transcriptional repressor and a key regulator of normal B-cell maturation and differentiation processes. Deregulation of BCL6 function (e.g., via chromosomal translocation, mutations) may lead to malignant transformation and development of NHL. During B-cell development, tightly controlled BCL6 protein expression regulates more than 600 genes to facilitate rapid B-cell proliferation and tolerance of somatic hypermutation and gene recombination for antibody generation. Deregulated BCL6 expression is common in B-cell lymphoma and promotes cancer cell survival, proliferation, and genomic instability. Prior to the advent of PROTAC technology, the BCL6 protein was considered "undruggable." We believe that ARV-393 PROTAC-mediated degradation of BCL6 may provide an important novel therapeutic option for patients with NHL, and that current preclinical data suggest that ARV-393 has the potential to be an attractive combination partner for development of novel therapies for lymphoma, including chemo-free combination regimens and/or “all oral” treatment options.

We are currently enrolling a Phase 1 first-in-human clinical trial of ARV-393 in patients with relapsed/refractory NHL. This is an open-label, multicenter, Phase 1 dose escalation study to evaluate the safety, tolerability and preliminary anti-tumor activity of ARV-393 as a single agent in adult patients with relapsed/refractory NHL. We plan to share preliminary clinical data from this ongoing Phase 1 clinical trial in patients with NHL in the second half of 2025.

In the second quarter of 2025, we presented preclinical data of ARV-393 in combination with standard of care, or SOC, chemotherapy and biologic agents, as well as oral, investigational small molecule inhibitors in high grade and aggressive diffuse large B-cell lymphoma, or DLBCL, in vivo models at the American Association for Cancer Research, or AACR, Annual Meeting. Based on these preclinical data, in aggressive DLBCL models, ARV-393 showed strong synergistic antitumor activity, including complete regressions, in combination with SOC chemotherapy and biologics, as well as investigational oral small molecule inhibitors. In particular:

Table of Contents

•ARV-393 in combination with SOC chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, or R-CHOP), induced significantly greater tumor growth inhibition, or TGI, compared with rituximab, CHOP, R-CHOP, or ARV-393 alone, with complete tumor regressions in all mice treated with the ARV-393 and R-CHOP combination;

•ARV-393 in combination with SOC biologics targeting CD20 (rituximab), CD19 (tafasitamab), or CD79b (polatuzumab vedotin), resulted in tumor regressions and demonstrated significantly stronger TGI compared with either agent alone;

•in preclinical models, ARV-393 increased CD20 expression, providing additional support for the exploration of combinations with CD20-targeted agents and in the context of low or loss of CD20 expression; and

•ARV-393 in combination with investigational small molecule inhibitors targeting clinically validated oncogenic drivers of lymphoma, such as BTK (acalabrutinib), BCL2 (venetoclax), or EZH2 (tazemetostat), resulted in superior tumor growth inhibition compared with each agent alone, with tumor regressions in all mice treated with the combinations.

We plan to present new preclinical data demonstrating single agent activity of ARV-393 in patient derived xenograft models of transformed Follicular Lymphoma and a patient-derived xenograft model of nTFHL-AI (angioimmunoblastic type of nodal T-follicular helper cell lymphoma), a rare and aggressive NHL with high unmet need and limited treatment options, for a presentation at the European Hematology Association 2025 conference in Milan, Italy in the second quarter of 2025. In addition, we plan to share preclinical data for ARV-393 in combination with an emerging SOC option in second-line DLBC in the second half of 2025.

Neuroscience Program: ARV-102

ARV-102 is our first oral PROTAC protein degrader in development to treat neurodegenerative diseases. In preclinical studies, ARV-102 has been shown to cross the blood-brain barrier and degrade LRRK2, which is a large, multidomain scaffolding kinase. Increased activity and expression of LRRK2 have been implicated in the pathogenesis of neurological diseases, including LRRK2 genetic and idiopathic Parkinson’s disease, or PD, and progressive supranuclear palsy.

We are currently conducting two ongoing clinical trials with ARV-102, a Phase 1 clinical trial in healthy volunteers and a Phase 1 clinical trial in patients with PD.

We completed enrollment for the single ascending dose, or SAD, and multiple ascending dose, or MAD cohorts of the ARV-102 Phase 1 clinical trial in healthy volunteers in the first quarter of 2025 and we expect to present final data from the SAD and MAD cohorts of this clinical trial in the second half of 2025.

Enrollment for the SAD cohort of the ARV-102 Phase 1 clinical trial in patients with PD is ongoing. We expect to present initial data from this clinical trial, as well as initiate the MAD cohort of this clinical trial, in the second half of 2025.

In the second quarter of 2025, we presented data from the first-in-human clinical trial of ARV-102 at the 2025 International Conference on Alzheimer’s and Parkinson’s Diseases, or AD/PD™ 2025, including results from the randomized, double-blind, placebo-controlled SAD cohort, and initial results from the MAD cohort, of the Phase 1 healthy volunteer clinical trial. The ARV-102 Phase 1 clinical trial is designed to assess the safety, pharmacokinetics, and pharmacodynamics of orally administered ARV-102 in healthy male volunteers. This clinical trial is a single-center, randomized, double-blind, placebo-controlled trial evaluating outcomes in both SAD and MAD cohorts. In the SAD cohort, volunteers were randomized three to one, to either placebo or a single dose of ARV-102 (10 mg, 30 mg, 60 mg, 90 mg, 150 mg, or 200 mg) on day 1 with follow-up until day 10. In the MAD cohort, volunteers were randomized to either placebo or a once daily dose of ARV-102 (10 mg, 20 mg, 40 mg, or 80 mg) for 14 days with follow-up until day 28.

In the clinical trial, ARV-102 demonstrated substantial reduction of LRRK2 in cerebral spinal fluid, or CSF, with a promising safety/tolerability profile and favorable pharmacodynamic outcomes. Key findings from the clinical trial indicated brain penetration, substantial central and peripheral LRRK2 protein degradation, and signified downstream LRRK2 pathway engagement. The specific data presented at AD/PD™ 2025 are outlined below.

Safety Profile

•At the time of data cutoff (March 13, 2025), the SAD cohort of the Phase 1 clinical trial was completed and the MAD cohort was ongoing. Based on evaluation of the available data from single and multiple oral doses, ARV-102 was well tolerated in healthy volunteers.

•Of the 47 volunteers across all SAD dose levels, the primary treatment related adverse events were headache and fatigue. Headaches occurred in 17.1% (6/35) of treated individuals compared to 0% (0/12) in placebo controls. Fatigue occurred in 8.6% (3/35) of the treated individuals compared to 25% (3/12) in placebo controls.

•Procedural pain associated with the lumbar puncture occurred in 28.6% (10/35) of treated individuals compared to 41.7% (5/12) in placebo controls. Post lumbar puncture syndrome was only observed in the treated cohort, at a rate of 17.1% (6/35).

•No serious adverse events were reported in either the SAD or MAD cohorts.

ARV-102 Exposure in Plasma and CSF

•ARV-102 exhibited median maximum concentration six hours after oral administration.

•The area under the concentration-time curve in the first 24 hours post dosing and the maximum plasma concentration increased in a dose-dependent manner and the median terminal plasma half-life was 73 hours.

•ARV-102 levels in CSF increased in a dose dependent manner in both the SAD and MAD cohorts.

Pharmacodynamic Evaluation

•At single doses of greater than or equal to 60 mg and repeated doses of greater than or equal to 20 mg, LRRK2 reduction of greater than 90% in peripheral blood mononuclear cells was observed.

•ARV-102 at single doses of greater than or equal to 30 mg induced greater than 50% decreases in peripheral phospho-Rab10T73, a LRRK2 substrate and biomarker for downstream LRRK2 activity; data for this endpoint in the MAD cohort is pending.

•ARV-102 at single doses of greater than or equal to 30 mg resulted in greater than 90% decrease of bis(monoacylglycerol)phosphate in urine, a biomarker of lysosomal function; data for this endpoint in the MAD cohort is pending.

•In CSF, ARV-102 induced dose-dependent LRRK2 reduction, with greater than 50% LRRK2 reduction at single doses of greater than or equal to 60 mg and repeated doses of greater than or equal to 20 mg.

Other Programs: ARV-806 and bavdegalutamide (ARV-110)

Kirsten rat sarcoma, or KRAS, is one of the most frequently mutated human oncogenes, is commonly altered in pancreatic, colorectal, and lung cancers, among others, and is associated with poor prognosis and resistance to standards of care. G12D is the most common mutation of the KRAS protein. ARV-806, our PROTAC KRAS G12D degrader, is a potent small molecule degrader of KRAS G12D and is designed to eliminate, rather than inhibit, KRAS G12D and, in preclinical studies, ARV-806 was 30-fold more potent than an inhibitor in vitro and provided additional aspects of differential biology contributing to its potent and broad antitumor effect in vivo. In addition, in the preclinical setting, ARV-806 demonstrated high potency and selectivity, with robust antitumor activity through dose-responsive degradation of KRAS G12D in KRAS G12D mutated cancers, including pancreatic and colorectal cancers.

We filed an investigational new drug application with the U.S. Food and Drug Administration, or FDA, for ARV-806 in the first quarter of 2025 and received a safe-to-proceed letter from the FDA in the second quarter of 2025. We expect to initiate a first-in-human Phase 1 clinical trial of ARV-806 in patients with solid tumors harboring KRAS G12D mutations in the second half of 2025.

Bavdegalutamide is an investigational orally bioavailable PROTAC protein degrader designed to target and degrade the androgen receptor, or AR, for the treatment of men with metastatic castration resistant prostate cancer. Clinical trials for bavdegalutamide (ARV-110-101 and ARV-110-103) were completed in the second quarter of 2025, and we are winding down the bavdegalutamide program.

Our Operations

We commenced operations in 2013. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, conducting discovery and research activities, filing patent applications, identifying potential product candidates, undertaking preclinical studies and clinical trials and establishing collaborations with third parties and for the manufacture of initial quantities of our product candidates and preparing for commercialization, including by beginning to build a commercial infrastructure. To date, we have not generated any revenue from product sales and have financed our operations primarily through sales of assets and equity interests, proceeds from our collaborations and a licensing arrangement, grant funding and debt financing. Since inception through March 31, 2025, we raised approximately $1.7 billion in gross proceeds from the sale of assets and equity interests and the exercise of stock options and had received an aggregate of $913.0 million in payments primarily from collaboration partners and a licensing arrangement.

We are a clinical-stage company, with product candidates in clinical development and other drug discovery activities in the research and preclinical development stages. Our ability to generate revenue from product sales sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our product candidates and our ability to manage our expenses. In April 2025, we committed to and approved a reduction of our workforce by approximately 33% across all all areas of our company, as part of our decision to streamline operations across our organization and enable the efficient progression of our portfolio. We expect the workforce reduction will be substantially completed by the end of the second quarter of 2025. We estimate that we will incur approximately $10.0 million in costs in connection with the workforce reduction, which consist of severance and other one-time employee termination benefit expenses which we expect to recognize primarily in the second quarter of 2025. Refer to Note 15 in this Quarterly Report on Form 10-Q for further details.

Since inception, we have incurred significant operating losses and, even in light of our workforce reduction, we expect to continue to incur increasing operating losses for at least the next several years. In addition to any additional costs not currently contemplated due to the events associated with or resulting from our workforce reduction, our ability to achieve profitability and our financial position will depend, in part, on the rate of our future expenditures, potential collaboration revenue, our ability to successfully implement cost avoidance measures and reduce overhead costs and our ability to obtain additional funding. We expect to continue to incur significant expenses associated with: our ongoing and anticipated preclinical and clinical activities, development activities, research activities in oncology, neuroscience and other disease areas, managing our employees and retaining key talent in research, clinical trials, quality and other functional areas, including general and administrative, sales and commercial as we move towards potential commercialization, increased expenses incurred with CMOs to supply us with product for our preclinical and clinical studies, and expenses incurred with contract research organizations, or CROs, for the synthesis of compounds in our

Table of Contents

preclinical development activities, as well as other associated costs including those related to partnering with us on our clinical trial portfolio and the management of our intellectual property portfolio.

We do not expect to generate any revenue from product sales in the near future, if ever. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research or product development programs or any future commercialization efforts, or to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us.

Financial Operations Overview

Revenue

To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products in the near future. Our revenues to date have been generated through research collaborations, a licensing arrangement and an asset sale. Revenue is recognized ratably over our expected performance period under each agreement. We expect that any revenue recognized in the near term will be derived from our current collaboration agreements and licensing arrangement and any additional arrangements that we may enter into in the future. To date, we have not received any development, regulatory and commercial milestone payments or royalties under any of the collaboration agreements or licensing arrangement.

Pfizer Vepdegestrant (ARV-471) Collaboration Agreement

In July 2021, we entered into a Collaboration Agreement with Pfizer, or the Vepdegestrant (ARV-471) Collaboration Agreement, pursuant to which we granted Pfizer worldwide co-exclusive rights to develop and commercialize products containing our proprietary compound vepdegestrant (ARV-471), or the Licensed Products.

Under the Vepdegestrant (ARV-471) Collaboration Agreement, we received an upfront, non-refundable payment of $650.0 million. In addition, we are eligible to receive up to an additional $1.4 billion in contingent payments based on specified regulatory and sales-based milestones for the Licensed Products. Of the total contingent payments, $400.0 million in regulatory milestones are related to marketing approvals and $1.0 billion are related to sales-based milestones.

We and Pfizer share equally (50/50) all development costs (including costs for conducting any clinical trials) for the Licensed Products, subject to certain exceptions. Except for certain regions described below, we will also share equally (50/50) all profits and losses in commercialization and medical affairs activities for the Licensed Products in all other countries, subject to certain exceptions.

We will be the marketing authorization holder and, subject to marketing approval, book sales in the United States, while Pfizer will hold marketing authorizations outside the United States. We will determine with Pfizer which, if any, regions within the world will be solely commercialized by one party, and in such region the parties will adjust their share of all profits and losses for the Licensed Products based on the role each party will be performing.

Unless earlier terminated in accordance with its terms, the Vepdegestrant (ARV-471) Collaboration Agreement will expire on a Licensed Product-by-Licensed Product and country-by-country basis when such Licensed Products are no longer commercialized or developed for commercialization in such country. Pfizer may terminate the Vepdegestrant (ARV-471) Collaboration Agreement for convenience in its entirety or on a region-by-region basis subject to certain notice periods. Either party may terminate the Vepdegestrant (ARV-471) Collaboration Agreement for the other party’s uncured material breach or insolvency. Subject to applicable terms of the Vepdegestrant (ARV-471) Collaboration Agreement, including certain payments to Pfizer upon termination for our uncured material breach, effective upon termination of the Vepdegestrant (ARV-471) Collaboration Agreement, we are entitled to retain specified licenses to be able to continue to exploit the Licensed Products.

Subject to specified exceptions, we and Pfizer have each agreed not to directly or indirectly research, develop, or commercialize any competing products outside of the Vepdegestrant (ARV-471) Collaboration Agreement anywhere in the world during the term of the Vepdegestrant (ARV-471) Collaboration Agreement.

Pfizer Research Collaboration Agreement

In December 2017, we entered into a Research Collaboration and License Agreement with Pfizer, setting forth our collaboration to identify or optimize PROTAC targeted protein degraders that mediate for degradation of target proteins, using our proprietary platform technology that are identified in the agreement or subsequently selected by Pfizer, subject to certain exclusions. We refer to this agreement as the Pfizer Research Collaboration Agreement.

Under the Pfizer Research Collaboration Agreement, Pfizer has designated a number of initial target proteins. For each identified target protein, we and Pfizer will conduct a separate research program pursuant to a research plan. Pfizer may make substitutions for any of the initial target proteins candidates, subject to the stage of research for such target protein.

In the year ended December 31, 2018, we received an upfront non-refundable payment and certain additional payments totaling $28.0 million in exchange for use of our technology license and to fund Pfizer-related research, as defined within the Pfizer Research Collaboration Agreement. We are eligible to receive up to an additional $3.8 million in non-refundable option payments if Pfizer exercises its option for the single target protein remaining under the Pfizer Research Collaboration Agreement. We are also entitled to receive up to $225.0 million in development milestone payments and up to $550.0 million in sales-based milestone payments for all designated target proteins under the Pfizer Research Collaboration Agreement, as well as mid- to high-single digit tiered royalties, which may be subject to reductions, on net sales of PROTAC targeted protein degrader-related products.

Novartis Transaction

In April 2024, we entered into a transaction, or the Novartis Transaction, including both a license agreement, or the Novartis License Agreement, and an asset agreement, or the Novartis Asset Agreement, with Novartis Pharma AG, or Novartis. The Novartis Transaction closed in May 2024 upon the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, at which time the Novartis License Agreement and the Novartis Asset Agreement became effective.

Pursuant to the Novartis License Agreement, we granted Novartis an exclusive worldwide license for the development, manufacture and commercialization of luxdegalutamide (ARV-766), our second generation PROTAC AR degrader for patients with prostate cancer. Pursuant to the Novartis Asset Agreement, we sold to Novartis all of our rights, title and interest in our PROTAC protein degrader targeting AR-V7, a splice variant of the AR.

Under the terms of and as consideration for entering into the Novartis Transaction, we received a one-time, upfront payment in the aggregate amount of $150.0 million from Novartis. Under the Novartis License Agreement, we are also eligible to receive up to an additional $1.01 billion as contingent payments based on specified development, regulatory, and commercial milestones for luxdegalutamide (ARV-766) being met, as well as tiered royalties based upon worldwide net sales of luxdegalutamide (ARV-766), subject to reduction under certain circumstances as provided in the Novartis License Agreement.

The Novartis License Agreement will expire on a country-by-country basis (or, in certain cases, a region-by-region basis) until the expiration of the applicable royalty term for such country (or region, as applicable). The Novartis License Agreement contains customary termination provisions, including that either party may terminate the Novartis License Agreement (a) upon the material breach of the other party or (b) in the event the other party experiences an insolvency event. Additionally, Novartis may terminate the Novartis License Agreement for convenience or upon a safety or regulatory issue.

Bayer Collaboration Agreement

In June 2019, we entered into a Collaboration and License Agreement, or the Bayer Collaboration Agreement, with Bayer, setting forth our collaboration to identify or optimize PROTAC targeted protein degraders that mediate for degradation of target proteins, using our proprietary platform technology, that are

selected by Bayer, subject to certain exclusions and limitations. The Bayer Collaboration Agreement became effective in July 2019.

Under the Bayer Collaboration Agreement, we and Bayer conducted a research program pursuant to separate research plans mutually agreed to by us and Bayer and tailored to each target protein selected by Bayer. During the term of the Bayer Collaboration Agreement, we were not permitted, either directly or indirectly, to design, identify, discover or develop any small molecule pharmacologically-active agent whose primary mechanism of action is, by design, directed to the inhibition or degradation of any target protein selected or reserved by Bayer, or grant any license, covenant not to sue or other right to any third party in the field of human disease under the licensed intellectual property for the conduct of such activities.

Under the terms of the Bayer Collaboration Agreement, we received an aggregate upfront non-refundable payment of $17.5 million and an additional $12.0 million in aggregate from inception through 2023. We were also eligible to receive up to $197.5 million in development milestone payments and up to $490.0 million in sales-based milestone payments for all designated target proteins. In addition, we were eligible to receive, on net sales of PROTAC targeted protein degrader-related products, mid-single digit to low-double digit tiered royalties, which were subject to reductions.

Pursuant to notice from Bayer AG in accordance with the terms of the Bayer Collaboration Agreement, the Bayer Collaboration Agreement was terminated, effective August 12, 2024.

Genentech License Agreement

In September 2015, we entered into an Option and License Agreement with Genentech focused on PROTAC targeted protein degrader discovery and research for target proteins based on our proprietary platform technology, other than excluded target proteins as described below. This collaboration was expanded in November 2017 through an Amended and Restated Option, License and Collaboration Agreement, which we refer to as the Restated Genentech Agreement.

Under the Restated Genentech Agreement, Genentech had the right to designate up to ten target proteins for further discovery and research utilizing our PROTAC platform technology and also had the right to remove a target protein from the collaboration and substitute a different target protein that was not an excluded target protein at any time prior to us commencing research on such target protein or in certain circumstances following commencement of research by us. The research phase of the collaboration with Genentech has ended. Genentech is no longer able to nominate new target proteins into the collaboration, and there are no active targets in the collaboration for which Arvinas was conducting research activities.

At the time we entered into the original agreement with Genentech, we received an upfront payment of $11.0 million, and at the time we entered into the Restated Genentech Agreement, we received an additional $34.5 million in upfront and expansion target payments. We are eligible to receive payments aggregating up to $44.0 million per target protein upon the achievement of specified development milestones; payments aggregating up to $52.5 million per target protein (assuming approval of two indications) subject to the achievement of specified regulatory milestones; and payments aggregating up to $60.0 million per PROTAC targeted protein degrader directed against the applicable target protein, subject to the achievement of specified sales milestones. These milestone payments are subject to reduction if we do not have a valid patent claim covering the licensed PROTAC targeted protein degrader at the time the milestone is achieved. We are also eligible to receive, on net sales of licensed PROTAC targeted protein degraders, mid-single digit royalties, which may be subject to reductions.

Operating Expenses

Our operating expenses since inception have consisted solely of research and development costs and general and administrative costs.

Table of Contents

Research and Development Expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our discovery efforts, and the development of our product candidates, and include:

•employee related expenses, including salaries, benefits, stock-based compensation expense and travel, for personnel engaged in research and development functions;

•expenses incurred under agreements with third parties, including CROs and other third parties that conduct research, preclinical and clinical activities on our behalf as well as third parties that manufacture our product candidates for use in our preclinical studies and clinical trials;

•costs of outside consultants, including their fees, stock-based compensation and related travel expenses;

•the costs of laboratory supplies and developing preclinical studies and clinical trial materials;

•facility-related expenses, which include direct depreciation costs of equipment and allocated expenses for rent and maintenance of facilities and other operating costs;

•costs incurred in the development of intellectual property; and

•third-party licensing fees.

We expense research and development costs as incurred.

We typically use our employee and infrastructure resources across our development programs, and as such, do not track all of our internal research and development expenses on a program-by-program basis. The following table summarizes our research and development expenses for the three months ended March 31, 2025 and 2024:


	For the Three Months Ended March 31,
(dollars in millions)	2025		2024



Program-specific external expense:
Vepdegestrant (ARV-471) (*)	$	24.1	$	19.1
ARV-102	6.5		1.3
ARV-393	2.6		1.2
Bavdegalutamide (ARV-110)	1.1		1.6
Luxdegalutamide (ARV-766)	—		3.6
Other programs	2.6		0.1
Total program-specific external expense	36.9		26.9
Non program-specific external expense	13.9		16.1
Unallocated internal expense
Compensation and related personnel expense (including stock-based compensation)	36.9		38.3
Other research and development expense	3.1		3.0
Total unallocated internal expense	40.0		41.3
Total research and development expense	$	90.8	$	84.3

(*) Includes net reimbursement to and from Pfizer pursuant to the Vepdegestrant (ARV-471) Collaboration Agreement.

Research and development activities are central to our business model. We expect that our research and development expenses will continue to increase substantially for the foreseeable future as we continue to conduct our ongoing clinical trials of vepdegestrant, ARV-102 and ARV-393 and continue to discover and

Table of Contents

develop additional product candidates. Research and development expenses related to vepdegestrant are shared equally with Pfizer since July 22, 2021, the effective date of the Vepdegestrant (ARV-471) Collaboration Agreement. We may receive reimbursement from, or make payments to, Pfizer to satisfy the cost sharing requirements. These payments are accounted for pursuant to ASC 808, Collaborative Arrangements, which are recorded as an offset or an increase to research and development expenses.

We cannot determine with certainty the duration and costs of ongoing and future clinical trials of vepdegestrant, ARV-102 and ARV-393, unexpected costs of planned clinical trials of ARV-806, or any other product candidate we may develop or if, when, or to what extent we will generate revenue from the commercialization and sale of any product candidate for which we obtain marketing approval. We may never succeed in obtaining marketing approval for any product candidate. The successful development and commercialization of our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

•successfully completing of preclinical studies and clinical trials;

•receipt and related terms of marketing approvals from applicable regulatory authorities;

•obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates;

•making or maintaining arrangements with third-party manufacturers, or establishing manufacturing capabilities, for both clinical and commercial supplies of our product candidates;

•establishing sales, marketing, market access and distribution capabilities and launching commercial sales of our products, if and when approved, whether alone or in collaboration with others;

•acceptance of our products, if and when approved, by patients, the medical community and third-party payors;

•obtaining and maintaining third-party coverage and adequate reimbursement;

•maintaining a continued acceptable safety profile of the products following approval; and

•effectively competing with other therapies.

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the U.S. Food and Drug Administration or another regulatory authority were to require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in our clinical trials due to patient enrollment or other reasons, we would be required to expend significant additional financial resources and time on the completion of clinical development.

General and Administrative Expenses

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

We expect that our general and administrative expenses will increase in the future as we manage our personnel, including retaining or hiring of key employees, and, as a result of any future need to increase our headcount to support research and development activities relating to our product candidates, develop our infrastructure and build out commercial operations for any potential launch of commercial sales of our products. We also expect to incur increased expenses associated with being a public company, including costs of accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with the Nasdaq Stock Market and U.S. Securities and Exchange Commission requirements; director and officer insurance costs; and investor and public relations costs.

Other Income

Other income consists primarily of interest income from marketable securities and money market accounts.

Income Taxes

Since our inception in 2013, we have not recorded any U.S. federal or state income tax benefits for the net losses we have incurred in any year or for our federal or state earned research and development tax credits, due to our uncertainty of realizing a benefit from those items.

As of December 31, 2024, we had $111.0 million of federal net operating loss carryforwards, all of which may be carried forward indefinitely, but the deductibility of such carryforwards is limited to 80% of our taxable income in the year in which carryforwards are used, $129.0 million of state and local net operating loss carryforwards which expire at various dates beginning in 2035, $37.7 million of federal tax credit carryforwards and $22.4 million of state tax credit carryforwards as of December 31, 2024 which expire at various dates beginning in 2040.

We expect to generate federal and state net operating losses and credit carryforwards in 2025 and future periods. The revenue recognition and capitalization of research expenses are timing differences for tax purposes and deferred tax assets were established. We have provided a valuation allowance against the full amount of the deferred tax assets since, in the opinion of management, based upon our earnings history, it is more likely than not that the benefits will not be realized.

As of March 31, 2025, Arvinas, Inc. had four wholly owned subsidiaries organized as C-corporations: Arvinas Operations, Inc., Arvinas Androgen Receptor, Inc., Arvinas Estrogen Receptor, Inc., and Arvinas Winchester, Inc.

Critical Accounting Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States. The preparation of our unaudited condensed consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, costs and expenses and the disclosure of contingent assets and liabilities in our unaudited condensed consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting estimates from those described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the Securities and Exchange Commission on February 11, 2025.

Revenue

Revenue for the three months ended March 31, 2025 totaled $188.8 million, compared to $25.3 million for the three months ended March 31, 2024. The increase of $163.5 million was primarily due to an increase in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer totaling $167.8 million related to changes in total program cost estimates resulting from the removal of the first-line Phase 3 combination trial with Pfizer’s novel investigational CDK4 inhibitor, atirmociclib, and the removal of the second-line Phase 3 combination trial with a CDK4/6 inhibitor from the development plan, offset by a decrease in revenue from the Pfizer Research Collaboration Agreement of $2.7 million due to changes in estimates of the performance period duration under the agreement resulting from updated research timelines and a decrease in revenue from the Bayer Collaboration Agreement of $1.6 million related to the termination of the Bayer Collaboration Agreement in August 2024.

Research and Development Expenses

Research and development expenses for the three months ended March 31, 2025 totaled $90.8 million, compared to $84.3 million for the three months ended March 31, 2024. The increase of $6.5 million was primarily due to an increase in external expenses of $7.8 million, partially offset by a decrease in compensation and related personnel expenses of $1.4 million, which are not allocated by program. External expenses include (i) program-specific expenses, which increased by $10.0 million, primarily driven by increases in our ARV-102, vepdegestrant (ARV-471), ARV-393 and other programs of $5.2 million, $5.0 million, $1.4 million and $2.5 million, respectively, partially offset by decreases in our luxdegalutamide (ARV-766) and bavdegalutamide (ARV-110) programs of $3.6 million and $0.5 million, respectively, and (ii) our non-program specific expenses, which decreased by $2.2 million.

Table of Contents

Non-GAAP research and development expenses for the three months ended March 31, 2025 totaled $79.3 million, compared to $71.9 million for the three months ended March 31, 2024, excluding $11.5 million and $12.4 million of non-cash stock-based compensation expense for the three months ended March 31, 2025 and 2024, respectively. We define non-GAAP research and development expenses as GAAP research and development expenses excluding stock-based compensation expense.

General and Administrative Expenses

General and administrative expenses totaled $26.6 million for the three months ended March 31, 2025, compared to $24.3 million for the three months ended March 31, 2024. The increase of $2.3 million was primarily due to an increase in professional fees of $2.4 million, inclusive of an increase in the amortization of costs to obtain a contract of $2.6 million related to changes in total Vepdegestrant (ARV-471) Collaboration Agreement program cost estimates resulting from the removal of two Phase 3 combination trials from the development plan and an increase in costs related to developing our commercial operations of $2.3 million, partially offset by a decrease in personnel and infrastructure related costs of $2.4 million.

Non-GAAP general and administrative expenses for the three months ended March 31, 2025 totaled $23.1 million, compared to $18.0 million for the three months ended March 31, 2024, excluding $3.5 million and $6.3 million of non-cash stock-based compensation expense for the three months ended March 31, 2025 and 2024, respectively. We define non-GAAP general and administrative expenses as GAAP general and administrative expenses excluding stock-based compensation expense.

Other Income

Other income totaled $11.7 million for the three months ended March 31, 2025, compared to $14.0 million for the three months ended March 31, 2024. The decrease of $2.3 million was primarily due to a decrease in interest income of $2.4 million on our marketable securities.

Income Tax Expense

Income tax expense totaled $0.2 million for the three months ended March 31, 2025, compared to $0.1 million for the three months ended March 31, 2024. The current and prior year tax expense was driven by the effect of equity compensation and the valuation allowance recorded against the full amount of our net deferred tax assets.

Non-GAAP Financial Information

We use the non-GAAP financial measures non-GAAP research and development expense and non-GAAP general and administrative expense, to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.

Liquidity and Capital Resources

Overview

We do not currently have any approved products and have never generated any revenue from product sales. To date, we have financed our operations primarily through the sales of assets and equity interests, proceeds from our collaborations and a license arrangement, grant funding and debt financing. Since inception through March 31, 2025, we had received an aggregate of $913.0 million in payments from collaboration partners and a licensing arrangement, grant funding and forgivable and partially forgivable loans from the State

Table of Contents

of Connecticut, and raised approximately $1.7 billion in gross proceeds from the sale of assets and equity interests, and the exercise of stock options, including:

•October 2018: completion of our initial public offering in which we issued and sold an aggregate of 7,700,482 shares of common stock, for aggregate gross proceeds of $123.2 million before fees and expenses;

•July 2019: sale of 1,346,313 shares of common stock to Bayer AG for aggregate gross proceeds of $32.5 million;

•November 2019: completion of a follow-on offering in which we issued and sold 5,227,273 shares of common stock for aggregate gross proceeds of $115.0 million before fees and expenses;

•September – December 2020: sale of 2,593,637 shares of common stock in an “at-the-market offering” for aggregate gross proceeds of $65.6 million before fees and expenses;

•December 2020: completion of a follow-on offering in which we issued and sold 6,571,428 shares of common stock for aggregate gross proceeds of $460.0 million before fees and expenses;

•September 2021: issuance of 3,457,815 shares of common stock to Pfizer for aggregate gross proceeds of $350.0 million;

•July - September 2023: sale of 1,449,275 shares of common stock in an “at-the-market offering” for aggregate gross proceeds of $37.2 million before fees and expenses;

•November 2023: sale of 12,963,542 shares of common stock and pre-funded warrants to purchase 3,422,380 shares of common stock in a private placement for aggregate gross proceeds of $350.0 million before fees and expenses; and

•April 2024: sale of AR-V7 to Novartis under the Novartis Asset Agreement for $20.0 million.

In November 2023, we amended and restated the Equity Distribution Agreement with Piper Sandler & Company and Cantor Fitzgerald & Co., pursuant to which we may offer and sell from time to time, through the agents, up to approximately $262.8 million of the common stock registered under our universal shelf registration statement pursuant to one or more “at-the-market" offerings. During the three months ended March 31, 2025, no shares were issued under the amended and restated agreement.

Cash Flows

Our cash, cash equivalents, restricted cash and marketable securities totaled $1.0 billion and $1.0 billion as of March 31, 2025 and December 31, 2024, respectively. We had an outstanding loan balance of $0.7 million and $0.8 million as of March 31, 2025 and December 31, 2024, respectively.

The following table summarizes our sources and uses of cash for the period presented:


	For the Three Months Ended March 31,
(dollars in millions)	2025		2024		$ change
Net cash used in operating activities	$	(88.9)	$	(97.5)	$	8.6
Net cash provided by (used in) by investing activities	69.5		(127.8)		197.3

Net decrease in cash, cash equivalents and restricted cash	$	(19.5)	$	(223.7)	$	204.2

Operating Activities

Net cash used in operating activities for the three months ended March 31, 2025 decreased by $8.6 million, compared with the three months ended March 31, 2024, primarily due to an increase in our net income of $152.3 million, as well as changes in accounts payable and accrued liabilities of $14.9 million, accounts receivable of $5.3 million, and an increase in non-cash charges of $0.6 million, partially offset by a decrease in

Table of Contents

deferred revenue of $163.6 million driven by changes in total Vepdegestrant (ARV-471) Collaboration Agreement program cost estimates resulting from the removal of two Phase 3 combination trials from the development plan. The change in non-cash charges was primarily due to an increase in the amortization of costs to obtain a contract of $2.9 million related to the changes in total Vepdegestrant (ARV-471) Collaboration Agreement noted above and net accretion of bond discounts/premiums of $1.7 million, partially offset by a decrease in stock-based compensation of $3.6 million.

Investing Activities

Net cash from investing activities for the three months ended March 31, 2025 increased by $197.3 million, compared with the three months ended March 31, 2024, primarily due to a net increase in maturities over a net decrease in purchases of marketable securities of $197.6 million, partially offset by an increase in purchases of property and equipment of $0.3 million.

Financing Activities

Net cash from financing activities for the three months ended March 31, 2025 decreased by $1.7 million, compared with the three months ended March 31, 2024, primarily due to decreased proceeds from the exercise of stock options, of which there were none during the three months ended March 31, 2025.

Funding Requirements

Since our inception, we have incurred significant operating losses. Even following our workforce reduction, where we expect to recognize cost savings, we expect to continue to incur significant expenses and increasing operating losses for the foreseeable future as we advance the preclinical and clinical development of our product candidates.

Specifically, we anticipate that our expenses will increase substantially if and as we:

•continue our ongoing and planned clinical trials of our product candidates, including vepdegestrant, for the treatment of patients with locally advanced or metastatic ER+/HER2- breast cancer, ARV-102, our PROTAC degrader designed to target the LRRK2 protein, and ARV-393, our PROTAC protein degrader designed to target the BCL6 protein, and progress ARV-806, our KRAS G12D program, into a planned first-in-human Phase 1 clinical trial;

•progress additional PROTAC protein degrader programs into IND- or CTA-enabling studies;

•apply our PROTAC Discovery Engine to advance additional product candidates into preclinical and clinical development;

•expand the capabilities of our PROTAC Discovery Engine;

•seek marketing approvals for any product candidates that successfully complete clinical trials;

•make decisions with respect to our personnel, including retention or future hiring of key employees, and establishment of a sales, marketing, market access, and distribution infrastructure to launch commercial sales of our products, if and when approved, whether alone or in collaboration with others;

•make decisions with respect to our infrastructure and capabilities, including to support our operations as a public company and our research, product development and future commercialization efforts;

•make or maintain arrangements with third-party manufacturers, or establish manufacturing capabilities, for both clinical and commercial supplies of our product candidates; and

•expand, maintain and protect our intellectual property portfolio.

We had cash, cash equivalents and marketable securities totaling approximately $1.0 billion as of March 31, 2025. We believe that our cash, cash equivalents and marketable securities as of March 31, 2025 will enable us to fund our planned operating expenses and capital expenditure requirements into the second half of 2028. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:

Table of Contents

•the progress, costs and results of our ongoing and planned clinical trials of vepdegestrant ARV-102 and ARV-393, and our planned clinical trials of ARV-806;

•the scope, progress, costs and results of preclinical and clinical development for our other product candidates and development programs;

•the number of, and development requirements for, other product candidates that we pursue, including our other oncology and neurodegenerative research programs;

•the success of our collaborations, including with Pfizer and Genentech;

•the costs, timing and outcome of regulatory review of our product candidates;

•the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval;

•the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

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

•our ability to establish additional collaboration arrangements with other biotechnology or pharmaceutical companies on favorable terms, if at all, or enter into license, marketing and royalty arrangements, and similar transactions for the development or commercialization of our product candidates.

As a result of these anticipated expenditures, we will need to obtain substantial additional financing in connection with our continuing operations. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. Although we may receive potential future payments under our collaborations, including with Pfizer and Genentech and our out-license to Novartis, we do not currently have any committed external source of funds. Adequate additional funds may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we may be required to delay, limit, reduce or terminate our research, product development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, the terms of these securities may include liquidation or other preferences that adversely affect the rights of our 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.

Borrowings

In June 2018, we entered into an additional assistance agreement with the State of Connecticut, or the 2018 Assistance Agreement, to provide funding for the expansion and renovation of laboratory and office space. We borrowed $2.0 million under the 2018 Assistance Agreement in September 2018, of which $1.0 million was forgiven upon meeting certain employment conditions. Borrowings under the agreement bear an interest rate of 3.25% per annum, with interest only payments required for the first 60 months, and mature in September 2028. The 2018 Assistance Agreement requires that we be located in the State of Connecticut through September 2028 with a default penalty of repayment of the full original funding amount of $2.0 million plus liquidated damages of 7.5% of the total amount of funding received. As of March 31, 2025, $0.7 million remains outstanding under the 2018 Assistance Agreement.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities. Our interest-earning assets consist of cash, cash equivalents and marketable securities. Interest income earned on these assets totaled $11.7 million and $14.0 million for the three months ended March 31, 2025 and 2024, respectively. Our interest income is sensitive to changes in the general level of interest rates, primarily U.S. interest rates. As of March 31, 2025, our cash equivalents consisted of bank deposits and money market funds, and our marketable securities included interest-earning securities. Our outstanding debt totaled $0.7 million and $0.8 million as of March 31, 2025 and December 31, 2024, respectively, and carries a fixed interest rate of 3.25% per annum.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer (our principal executive officer and principal financial officer, respectively), evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2025. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2025, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended March 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in litigation or other legal proceedings arising in the ordinary course of business and regardless of outcome, litigation can have an adverse impact on our business, financial condition, results of operations and prospects because of defense and settlement costs, diversion of management resources and other factors. We are not currently a party to any material litigation or legal proceedings.

Item 1A. Risk Factors.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties discussed in “Part I, Item 1A, Risk Factors,” in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission, or SEC, on February 11, 2025, together with all of the other information contained in this Quarterly Report on Form 10-Q, including our unaudited condensed consolidated financial statements and the related notes appearing elsewhere in this Quarterly Report on Form 10-Q. New or revised 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 factor disclosures in our Annual Report on Form 10-K for the year ended December 31, 2024 are qualified by the information that is described in this Quarterly Report on Form 10-Q. If any of the risks in our Annual Report on Form 10-K for the year ended December 31, 2024 actually occur, our business, prospects, operating results and financial condition could suffer materially. In such an event, the trading price of our common stock could decline and you might lose all or part of your investment. The new and revised risks described below and the risks described in our Annual Report on Form 10-K for the year ended December 31, 2024 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.

New Risk Factors

In addition to the risks included in our Annual Report on Form 10-K for the year ended December 31, 2024, the following risks may also affect our business:

Our cost savings plan and the associated workforce reduction implemented in April 2025 may not result in anticipated savings, could result in total costs and expenses that are greater than expected and could disrupt our business.

In April 2025, we committed to and approved a reduction in our workforce by approximately 33% across all areas of our company, as part of the Company's decision to streamline operations across the organization and enable the efficient progression of the Company’s portfolio. We may not realize, in full or in part, the anticipated benefits, savings and improvements in our cost structure from our cost savings plan and associated workforce reduction due to unforeseen difficulties, delays or unexpected costs. If we are unable to realize the expected operational efficiencies and cost savings from our cost savings plan and associated workforce reduction, our operating results and financial condition would be adversely affected. We also cannot guarantee that we will not have to undertake additional workforce reductions or restructuring activities in the future. Furthermore, our cost savings plan may be disruptive to our operations, including conducting clinical trials and potentially commercializing our product candidates, including vepdegestrant, which could affect our ability to generate product revenue. In addition, our reductions in workforce could yield unanticipated consequences, such as attrition beyond planned staff reductions, or disruptions in our day-to-day operations. Our workforce reduction could also harm our ability to attract and retain qualified management, scientific, clinical, manufacturing and sales and marketing personnel who are critical to our business. Any failure to attract or retain qualified personnel could prevent us from successfully developing and commercializing, if approved, our product candidates, including vepdegestrant, ARV-393, ARV-102, and ARV-806, in the future.

Disruptions at the U.S. Food and Drug Administration, or FDA, and other government agencies from funding cuts, personnel losses, regulatory reform, government shutdowns and other developments could hinder our ability to obtain guidance from the FDA regarding our clinical

development program and develop and secure approval of our product candidates in a timely manner, which would negatively impact our business.

The FDA and comparable regulatory agencies in foreign jurisdictions, such as the European Medicines Agency, or EMA, play an important role in the development of our product candidates by providing guidance on our clinical development programs and reviewing our regulatory submissions, including investigational new drug applications, or INDs, requests for special designations and marketing applications. If these oversight and review activities are disrupted, then correspondingly our ability to develop and secure timely approval of our product candidates could be impacted in a negative manner.

For example, the recent loss of FDA leadership and personnel could lead to disruptions and delays in FDA guidance, review and approval of our product candidates. Pursuant to President Trump's Executive Order, or E.O., 14210, “Implementing the President’s ‘Department of Government Efficiency’ Workforce Optimization Initiative,” the Secretary of Health and Human Services, or HHS, announced on March 27, 2025, a reorganization and reduction in force, or RIF, across the Department of HHS of approximately 20,000 employees (82,000 to 62,000), with FDA’s workforce to decrease by 3,500 full-time employees. Shortly thereafter, thousands of employees at the FDA were fired on April 1, 2025. Subsequently, there have been reports from the preliminary budget memorandum for HHS that the administration will propose an additional 30% cut in the overall budget for HHS, with a reduction of $700 million in funding at the FDA ($7.2 billion to $6.5 billion) for the 2026 federal fiscal year.

Further, while the FDA’s review of marketing applications and other activities for new drugs and biologics is largely funded through the user fee program established under the Prescription Drug User Fee Act, or PDUFA, it remains unclear how the administration’s RIF and budget cuts will impact this program and the ability of the FDA to provide guidance and review our product candidates in a timely manner. For example, while the FDA RIF did not reportedly specifically target FDA reviewers, many operations, administrative and policy staff that help support such reviews were affected and those losses could lead to delays in PDUFA reviews and related activities. In addition, while currently unclear, there is a risk that the RIF and budget cutbacks could threaten the integrity of the PDUFA program itself. That is because, for the FDA to obligate user fees collected under PDUFA in the first place, a certain amount of non-user fee appropriations must be spent on the process for the review of applications plus certain other costs during the same fiscal year.

There is also substantial uncertainty as to how regulatory reform measures being implemented by the Trump Administration across the government will impact the FDA and other federal agencies with jurisdiction over our activities. For example, since taking office, the President has issued a number of executive orders that could have a significant impact on the manner in which the FDA conducts its operations and engages in regulatory and oversight activities. These include E.O. 14192, “Unleashing Prosperity Through Deregulation,” January 31, 2025; E.O. 14212, “Establishing the President’s Make America Healthy Again Commission,” February 13, 2025; and E.O. 14219, Ensuring Lawful Governance and Implementing the President’s ‘Department of Government Efficiency” Deregulatory Initiative,” February 21, 2025. If these or other orders or executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.

Similarly, actions by the U.S. government have significantly disrupted the operations of U.S. government agencies such as the National Institutes of Health, National Science Foundation, Centers for Disease Control and Prevention, and FDA, which have traditionally provided funding for basic research, research and development, and clinical testing. These U.S. government actions have included, among other things, suspending, terminating and withholding of disbursements of funds owed under ongoing contracts, grants, and other financial assistance agreements; declining to continue multi-year research projects for additional annual budget periods; canceling or delaying solicitations for new contract, grant and other financial assistance awards; canceling or delaying proposal evaluation processes and issuance of such new awards; substantially reducing federal agency staff responsible for managing contract and financial assistance programs; eliminating agency information and resources for facilitating research activity; delaying or terminating federal agency procedures for authorizing international transactions; initiating aggressive enforcement actions that may disrupt the operations of major research universities that are significant contributors to life sciences research in the U.S., and threatening access to federal agency contracts and other funding awards based on companies’ otherwise lawful corporate policies and choice of counsel. These U.S. government actions could, directly or indirectly, significantly disrupt, delay, prevent, or increase the costs of our research and product commercialization programs, including our ability to develop new product candidates, conduct clinical trials,

Table of Contents

implement research collaborations with other companies or institutions, and obtain approvals to market and sell new products.

In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions and could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

At the same time, disruptions at the FDA and other government agencies may result from public health events similar to the COVID-19 pandemic. For example, during the pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. In the event of a similar public health emergency in the future, the FDA may not be able to continue its current pace and review timelines could be extended. Regulatory authorities outside the United States facing similar circumstances may adopt similar restrictions or other policy measures in response to a similar public health emergency and may also experience delays in their regulatory activities.

Accordingly, if any of the foregoing developments and others impact the ability of the FDA to provide us with guidance regarding our clinical development programs or delay the agency’s review and processing of our regulatory submissions, including INDs and new drug applications or biologic license applications, our business would be negatively impacted. Further, any future government shutdown could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Amended Risk Factors

The risks listed below, which were included in our Annual Report on Form 10-K for the year ended December 31, 2024, are replaced in their entirety by the following.

We have incurred significant losses since our inception. We expect to incur losses over at least the next several years and may never achieve or maintain profitability.

Our net losses totaled $198.9 million, $367.3 million and $282.5 million for the years ended December 31, 2024, 2023, and 2022, respectively. As of December 31, 2024, we had an accumulated deficit of $1,531.6 million. Although we had income of $82.9 million for the quarter ended March 31, 2025, we have historically incurred losses, and expect to continue to incur losses in the future. To date, we have not generated any revenue from product sales and have financed our operations primarily through sales of our assets and equity interests, proceeds from our collaborations, grant funding and debt financing. We are still in the early stages of development of our product candidates, and we have not completed development of any product candidates.

Our ability to achieve profitability also depends on our ability to manage our expenses. In April 2025, we committed to and approved a reduction in our workforce by approximately 33% across all areas of our company, as part of our decision to streamline operations across the organization and enable the efficient progression of our portfolio. We expect the workforce reduction will be substantially completed by the end of the second quarter of 2025, and we estimate that we will incur approximately $10.0 million in costs in connection with the workforce reduction, which consist of severance and other one-time employee termination benefit expenses which we expect to recognize primarily in the second quarter of 2025. The estimates of costs that we expect to incur, and the timing thereof, are subject to a number of assumptions and actual results may differ. Additionally, the workforce reduction could impact our operations, including our planned submission of an NDA to the FDA for vepdegestrant, which could affect our ability to generate future revenue.

We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. In addition to any additional costs not currently contemplated due to events associated with or resulting from the workforce reduction noted above, our ability to achieve profitability and our financial position will depend, in part, on the rate of our future expenditures, on product revenue, if any, collaboration revenue, if any, and our ability to obtain additional funding. We expect to continue to incur significant expenses and anticipate that our expenses will increase substantially if and as we:

Table of Contents

•progress additional PROTAC protein degrader programs into IND- or CTA-enabling studies;

•apply our PROTAC Discovery Engine to advance additional product candidates into preclinical and clinical development;

•expand the capabilities of our PROTAC Discovery Engine;

•seek marketing approvals for any product candidates that successfully complete clinical trials;

•make or maintain arrangements with third-party manufacturers, or establish manufacturing capabilities, for both clinical and commercial supplies of our product candidates; and

•expand, maintain and protect our intellectual property portfolio.

Our expenses could increase beyond our expectations if we are required by the FDA, EMA, or other regulatory authorities to perform trials in addition to those that we currently expect or anticipate, or if there are any delays in establishing appropriate manufacturing arrangements for or in completing our clinical trials or the development of any of our current or future product candidates.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses we will incur or when, if ever, we will be able to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our product offerings or even continue our operations. A decline in the value of our company could also cause our stockholders to lose all or part of their investment.

We will need substantial additional funding to continue our operations. If we are unable to raise capital when needed, we may be required to delay, limit, reduce or terminate our research or product development programs or future commercialization efforts.

We expect our expenses to continue to increase substantially in connection with our ongoing activities, particularly as we continue our ongoing and initiate our planned clinical trials of vepdegestrant, ARV-393 and ARV-102, initiate our planned clinical trial of ARV-806, advance our other oncology programs and neurodegenerative programs, and continue research and development and initiate additional clinical trials of and potentially seek marketing approval for our lead programs and our other product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. We continue to incur significant costs associated with operating as a public company. In addition, we will incur certain costs in connection with our reduction in workforce, and may incur additional costs not currently contemplated due to events associated with or resulting from the reduction in workforce and the charge that we expect to incur in connection with the workforce reduction is an estimate and subject to a number of assumptions, and actual results may differ materially. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on acceptable terms or not at all, we may be required to delay, limit, reduce or terminate our research, product development programs or any future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We had cash, cash equivalents and marketable securities totaling approximately $1.0 billion as of March 31, 2025. Based on our current operating plan, we believe that our cash, cash equivalents and marketable securities as of March 31, 2025 will enable us to fund our planned operating expenses and capital expenditure requirements into the second half of 2028. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including:

•the progress, costs and results of our ongoing and planned clinical trials of vepdegestrant, ARV-102 and ARV-393, and our planned clinical trial of ARV-806;

•the scope, progress, costs and results of preclinical and clinical development for our other product candidates and development programs;

•the number of, and development requirements for, other product candidates that we pursue, including our other oncology and neurodegenerative research programs;

•the success of our collaborations, including with Pfizer and Genentech;

•the costs, timing and outcome of regulatory review of our product candidates;

•the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for many years, if at all. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives. Adequate additional funds may not be available to us on acceptable terms, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs and product candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. For example, though we have since out-licensed luxdegalutamide (ARV-766) to Novartis and completed our clinical trials for bavdegalutamide, in 2023, we announced that we planned to prioritize the initiation of a Phase 3 clinical trial with luxdegalutamide (ARV-766) in metastatic castration resistant prostate cancer instead of the previously planned Phase 3 clinical trial for bavdegalutamide. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. In addition, the workforce reduction may cause us to reprioritize our portfolio and evaluate future strategic decisions.

Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the

Table of Contents

commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing, marketing or other royalty arrangements or similar transactions in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

Our future success depends on our ability to retain key employees, consultants and advisors and to attract, train, retain and motivate qualified personnel.

Our ability to compete in the highly competitive biopharmaceuticals industry depends upon our ability to attract, retain and motivate highly skilled and experienced personnel with scientific, medical, regulatory, manufacturing and management skills and experience. Although we have offer letters or employment agreements with each of our executive officers, each of them may terminate their employment with us at any time. We do not maintain “key person” insurance for any of our executives or other employees.

Recruiting and retaining qualified scientific, clinical, manufacturing, sales, marketing and market access personnel has been and will continue to be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. We may also need to grow the size of our organization in the future based on how our organization evolves and managing future growth will involve implementation and improvement of our managerial, operational and financial systems and procedures and recruitment and training of additional qualified personnel. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

Furthermore, attracting or replacing executive officers and key employees, consultants and advisors may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain marketing approval of and commercialize products. Our workforce reduction could also harm our ability to attract and retain qualified management, scientific, clinical, manufacturing and sales and marketing personnel who are critical to our business. In addition, we may not be able to retain our existing employees or hire new employees quickly enough to meet our needs. At the same time, we may face high turnover, requiring us to expend time and resources to source, train and integrate new employees.

While we offer remote and hybrid work arrangements, allowing us to seek talent from outside our New Haven headquarters area, we still may not be able to attract or retain qualified personnel in the future due to the intense competition for a limited number of qualified personnel among biopharmaceutical companies. Many of the other biopharmaceutical companies against which we compete have greater financial and other resources, different risk profiles and a longer history in the industry than we do. Our competitors may provide higher compensation, more diverse opportunities and/or better opportunities for career advancement. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. Any or all of these competing factors may limit our ability to continue to attract and retain high quality personnel, which could negatively affect our ability to successfully develop and commercialize our investigational products and to grow our business and operations as currently contemplated.

In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategies. These consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract, train, retain and motivate high quality personnel, our ability to pursue our corporate growth strategy will be limited.

Deleted Risk Factor

The risk factor included in our Annual Report on Form 10-K for the year ended December 31, 2024 "We will need to grow the size of our organization, and we may experience difficulties in managing this growth, which could disrupt our operations." is hereby deleted in its entirety.
