CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements of historical facts, contained in this Quarterly Report on Form 10-Q, including statements regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans and objectives of management, are forward-looking statements. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “predict,” “project,” “target,” “potential,” “goals,” “will,” “would,” “could,” “should,” “continue” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

The forward-looking statements in this Quarterly Report on Form 10-Q include, among other things, statements about:

•the initiation, timing, progress and results of our current and/or future clinical trials of ARV-393, ARV-102, ARV-027 and ARV-806, including statements regarding the period during which the results of the clinical trials will become available or the forum in which we will present such results;

•the initiation, timing, progress and results of our current preclinical studies and any future preclinical studies or clinical trials of our other programs, including ARV-6723 and our pan-KRAS degrader, including statements regarding the period during which the results of preclinical studies or clinical trials will become available or the forum in which we will present such results;

•our belief, based on data from our preclinical studies and clinical trials, that PROTAC protein degraders may have distinct advantages over traditional small molecule inhibitors, antibodies and gene-based medicines;

•our belief that PROTAC degraders offer distinct advantages that enable perturbation of protein targets traditionally considered undruggable by conventional therapeutics;

•the timing of, and our ability to obtain, marketing approval of our product candidates and the ability of our product candidates to meet existing or future regulatory standards;

•our plans to pursue research and development of other product candidates;

•the potential advantages of our platform technology and potential advantages and therapeutic benefits of our product candidates;

•our belief that and the extent to which our targeted protein degradation approach may provide distinct advantages over existing therapies and address a broad range of targets, including historically undruggable proteins, in areas of significant unmet need;

•the potential achievement of milestones and receipt of payments under our collaborations and license agreements, including our license agreement with Pfizer Inc. and Rigel Pharmaceuticals, Inc.;

•the potential receipt of payments based on the achievement of milestones related to luxdegalutamide (ARV-766) and future royalties under our license agreement with Novartis Pharma AG;

•the potential payments to be made to Yale University ("Yale") under our amended and restated license agreement with Yale;

•favorable clinical trial results in our ongoing oncology and neurology programs providing further validation of our platform as a new therapeutic modality for the potential treatment of diseases caused by dysregulated intracellular proteins;

•our belief that our leucine-rich repeat kinase 2 ("LRRK2") degraders are particularly well positioned tobe evaluated in neurodegenerative diseases where there are currently no disease modifying therapies available, including progressive supranuclear palsy ("PSP") and Parkinson's disease ("PD");

•our belief that the data from our preclinical studies of ARV-102 further support the potential of PROTAC-induced LRRK2 degradation as a treatment for patients with neurodegenerative disease;

•our belief that ARV-806 has the potential to address high unmet need in solid tumors, such as pancreatic, colorectal and non-small cell lung cancer ("NSCLC"), with Kirsten rat sarcoma G12D mutation;

ii

•our belief that ARV-806 has the potential to be developed as a monotherapy and in combination with chemotherapy in pancreatic ductal adenocarcinoma and in combination with standard of care ("SOC") treatments in colorectal and non-small cell lung cancer;

•our belief that preclinical data for ARV-806 supports intermittent clinical dosing;

•our plans to seek an out-licensing agreement for any additional clinical trials, including dose expansion or combination clinical trials, for ARV-806;

•our belief that ARV-027 has the potential to become the first treatment option for patients with spinal bulbar muscular atrophy, where no therapies have been approved the U.S. or European Union;

•our belief that PROTAC-mediated degradation has the potential to address the historically undruggable nature of the B-cell lymphoma 6 protein ("BCL6") and that ARV-393 PROTAC-mediated degradation of BCL6 may provide an important novel therapeutic option for patients with non-Hodgkin lymphoma ("NHL");

•our belief that ARV-393 can be an attractive combination partner for development of novel therapies for lymphoma, including chemo-free combination regimens and/or “all oral” treatment options;

•our belief that the totality of our preclinical data for ARV-393 provides a compelling rationale to evaluate ARV-393 in combination with bi-specifics, oral pathway inhibitors, and potentially other standards of care, in the larger diffuse large B-cell lymphoma indication;

•our belief that the higher-than-predicted proportion of patients with T-cell lymphomas, when compared to the overall lymphoma population, in the early monotherapy cohorts of the Phase 1 clinical trial of ARV-393 in patients with relapsed/refractory NHL may reflect the limited treatment options for these patients;

•the potential receipt of revenue from future sales of our product candidates;

•the rate and degree of market acceptance and clinical utility of our product candidates;

•our estimates regarding the potential market opportunity for our product candidates;

•our ability to manage the search for a new chief medical officer;

•our commercialization plans, and sales, marketing and distribution capabilities and strategy;

•our ability to establish and maintain arrangements for manufacture and testing of our product candidates;

•our ability to enter into additional collaborations with third parties;

•our intellectual property position;

•our plans with respect to our strategy;

•our estimates regarding expenses, future revenues, capital requirements and needs for additional financing, and statements regarding our cash, cash equivalents and marketable securities, including their sufficiency to fund planned operating expenses and capital expenditure requirements into the second half of 2028;

•our belief that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance;

•the impact of any government laws and regulations; and

•our competitive position.
