Pipeline ARV-102: Oral PROTAC LRRK2 degrader Announced the acceptance of data from the multiple dose cohort of the Phase 1 clinical trial in patients with Parkinson’s disease for an oral presentation at the International Conference on Alzheimer’s and Parkinson’s Diseases and Related Neurological Disorders (AD/PD) in March 2026. In addition to safety, PK and LRRK2 degradation data, the presentation will include disease-relevant pathway biomarker results in patients with Parkinson’s disease. Presented positive data from two Phase 1 clinical trials in an oral session at the International Congress of Parkinson’s Disease and Movement Disorders. ARV-806: Novel PROTAC KRAS G12D degrader Presented preclinical data for ARV-806, demonstrating robust and differentiated activity in models of KRAS G12D-mutated cancer, at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics. In vivo, ARV-806 demonstrated robust and durable KRAS G12D degradation, leading to significant tumor growth inhibition in models of pancreatic, colorectal, and lung cancer. ARV-806 showed a differentiated pro KRAS inhibitors and degraders currently in the clinic based on potency, antiproliferative activity, and induction of cancer cell death. Compared with clinical-stage inhibitors and another clinical-stage G12D degrader, ARV-806 demonstrated: >25-fold greater potency in reducing cancer cell proliferation. >40-fold higher potency in degrading KRAS G12D protein (versus the comparable clinical-stage G12D degrader). Completed dose escalation for once-weekly administration ahead of plan based on faster-than-anticipated enrollment in the Phase 1 clinical trial evaluating ARV-806 in patients with solid tumors harboring KRAS G12D mutations (ClinicalTrials.gov Identifier: NCT07023731). ARV-393: Oral PROTAC BCL6 degrader Continued dose escalation in the Phase 1 trial in patients with non-Hodgkin’s lymphoma (NHL) and announced there have been multiple responses in early cohorts at doses below the predicted effective exposure level in patients with both B-and T-cell lymphomas. Presented preclinical data at the 2025 American Society of Hematology Annual Meeting supporting mechanistic synergies and enhanced antitumor activity when combining ARV-393 and glofitamab: ARV-393 (3 mg/kg) combined with glofitamab (0.15 mg/kg) achieved 81% tumor growth inhibition (TGI) with concomitant dosing and 91% TGI with sequential dosing, versus 38% and 36% respectively for single agent use. RNA sequencing and biomarker analyses revealed that ARV-393 upregulated CD20 expression and genes that promote interferon signaling and antigen presentation, while downregulating proliferation-associated gene sets. Data support initiation of a combination cohort in the ongoing Phase 1 clinical trial to evaluate ARV-393 plus glofitamab as a chemotherapy-free combination approach in diffuse large B-cell lymphoma (DLBCL). ARV-027: Oral PROTAC polyQ-AR degrader Initiated a first-in-human Phase 1 clinical trial in healthy volunteers Presented new preclinical data at the International Congress of the World Muscle Society demonstrating induced robust degradation of polyQ-AR in human myotubes derived from spinal bulbar muscular atrophy (SBMA) patient-induced pluripotent stem cells, as well as: Dose-dependent degradation of polyQ-AR in mouse muscle that was sustained for more than 24 hours (single oral dose). Reductions in muscle monomeric polyQ-AR levels between 40-60%, improved muscle grip strength, and restored muscle endurance to wild-type levels in an SBMA mouse model. ARV-6723: Oral PROTAC HPK1 degrader Presented preclinical data at the Society for Immunotherapy of Cancer (SITC) Annual Meeting that support the potential of ARV-6723 to provide sustained anti-tumor immune response as a single agent or in combination with standards of care with improved clinical benefits: ARV-6723, as a single agent, demonstrates anti-tumor efficacy superior to anti-PD1 or a clinical HPK1 inhibitor and combines with anti-PD1 to further enhance response. ARV-6723 single agent activity outperforms the HPK1 inhibitor and anti-PD-1 efficacy and reinstitutes the tumor microenvironment. Presented preclinical data at the American Association for Cancer Research Immuno-Oncology Conference that support clinical investigation of ARV-6723 in patients with solid tumors harboring high- or low-immunogenic tumor microenvironments (TME), including ICI-resistant tumor settings: Robust single-agent antitumor and proinflammatory activity in multiple syngeneic tumor models, including those with immunosuppressive TMEs, and showed greater preclinical activity than an investigational HPK1i or an anti-PD-1 antibody. Vepdegestrant: Oral PROTAC ER degrader As part of Arvinas global collaboration with Pfizer, the companies: Presented five posters at the San Antonio Breast Cancer Symposium, further supporting the potential of vepdegestrant as a potential treatment option for patients with ESR1-mutated ER+/HER2- advanced breast cancer previously treated with endocrine-based therapy.

Advance towards Prescription Drug User Fee Act (PDUFA) action date on June 5, 2026. Financial Guidance Based on its current operating plan, Arvinas believes its cash, cash equivalents, and marketable securities as of December 31, 2025, is sufficient to fund planned operating expenses and capital expenditure requirements into the second half of 2028. Full Year and Fourth Quarter Financial Results Cash, Cash Equivalents, and Marketable Securities Position : As of December 31, 2025, cash, cash equivalents and marketable securities were $685.4 million as compared with $1,039.4 million as of December 31, 2024. The decrease in cash, cash equivalents and marketable securities of $354.0 million for the 12 months ended December 31, 2025 was primarily related to cash used in operations of $261.0 million and repurchases of our common shares under our Stock Repurchase Program of $91.9 million. Research and Development Expenses: Generally Accepted Accounting Principles (GAAP) Research and development (R&D) expenses were $285.2 million and $61.1 million for the year and quarter ended December 31, 2025, respectively, as compared with $348.2 million and $83.3 million for the year and quarter ended December 31, 2024, respectively. The decrease in R&D expenses of $63.0 million for the year was primarily due to a decrease in compensation and related personnel expenses of $35.8 million, which are not allocated by program, and a decrease in external expenses of $25.4 million. External expenses include program-specific expenses, which decreased by $11.7 million, driven by decreases in our luxdegalutamide, vepdegestrant and bavdegalutamide programs of $19.7 million, $14.2 million and $5.8 million, respectively, partially offset by increases in our ARV-806, ARV-102 and ARV-393 programs of $11.2 million, $8.0 million and $4.3 million, respectively and our non-program specific expenses, which decreased by $13.7 million. The decrease in R&D expenses of $22.2 million for the quarter was primarily due to a decrease in external expenses of $7.6 million and a decrease in compensation and related personnel expenses of $14.1 million. External expenses include non-program specific expenses, which decreased by $8.1 million and program-specific expenses, which increased by $0.5 million, driven primarily by increases in ARV-806 of $4.5 million, partially offset by decreases in vepdegestrant (ARV-471) of $3.8 million. Non-GAAP R&D expenses were $252.2 million for the year ended of December 31, 2025, as compared with $298.5 million for the year ended of December 31, 2024, excluding $2.3 million of restructuring expense for the year ended December 31, 2025, and $30.7 million and $49.7 million of non-cash stock-based compensation expenses for the year ended December 31, 2025, and 2024, respectively. Non-GAAP R&D expenses were $56.5 million for the quarter ended of December 31, 2025, as compared with $70.4 million for the quarter ended of December 31, 2024, excluding $1.3 million of restructuring expense for the quarter ended December 31, 2025, and $3.3 million and $12.9 million of non-cash stock-based compensation expenses for the quarter ended December 31, 2025, and 2024, respectively. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release. General and Administrative Expenses: GAAP General and administrative (G&A) expenses were $95.9 million and $23.0 million for the year and quarter ended of December 31, 2025, respectively, as compared with $165.4 million and $34.1 million for the year and quarter ended of December 31, 2024, respectively. The decrease in G&A expenses of $69.5 million for the year was primarily due to a loss on the termination of our laboratory and office space lease with 101 College Street LLC in August 2024 of $43.4 million, decrease in personnel and infrastructure related costs of $18.9 million and a decrease in professional fees of $6.6 million. The decrease in G&A expenses of $11.1 million for the quarter was primarily due to a decrease in personnel and infrastructure related costs of $4.4 million, a decrease in professional fees of $3.2 million and a decrease in costs related to developing our commercial operations of $3.1 million. Non-GAAP G&A expenses were $71.2 million for the year ended of December 31, 2025, as compared with $126.9 million for the year ended of December 31, 2024, excluding $1.3 million of restructuring expense for the year ended December 31, 2025 and $23.4 million and $38.5 million of non-cash stock-based compensation expenses for the year ended December 31, 2025 and 2024, respectively. Non-GAAP G&A expenses were $15.3 million for the quarter ended of December 31, 2025, as compared with $23.7 million for the quarter ended of December 31, 2024, excluding $1.6 million of restructuring expense for the quarter ended December 31, 2025 and $6.1 million and $10.4 million of non-cash stock-based compensation expenses for the quarter ended December 31, 2025 and 2024, respectively. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release. Revenue: Revenue was $262.6 million and $9.5 million for the year and quarter ended December 31, 2025, respectively, as compared with $263.4 million and $59.2 million for the year and quarter ended December 31, 2024, respectively. The decrease in revenue of $0.8 million for the year was primarily due to a decrease of $162.4 million of revenue from the Novartis License Agreement and the Novartis Asset Agreement as we completed the technology transfer of our ongoing and planned clinical trials of luxdegalutamide (ARV-766) to Novartis in 2024 and a decrease of $5.1 million of revenue from the Pfizer Research Collaboration Agreement due to changes in estimates of the performance period duration under the agreement resulting from updated research timelines, offset by an increase in revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer of $150.5 million related primarily 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, and the recognition of $20.0 million for achievement of a development milestone pursuant to the terms of the Novartis License Agreement. The decrease in revenue of $49.7 million for the quarter was primarily related to a decrease of $40.3 million of revenue from the Novartis License Agreement and the Novartis Asset Agreement after completing the technology transfer to Novartis in 2024 and a decrease of $7.4 million of revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer. Investor Call & Webcast Details Arvinas will host a conference call and webcast today, February 24, 2026, at 8:00 a.m. ET to review its fourth quarter and full year 2025 financial results and discuss recent corporate updates. Participants are invited to listen by going to the Events and Presentation section under the Investors page on the Arvinas website at A replay of the webcast will be available on the Arvinas website following the completion of the event and will be archived for up to 30 days. About ARV-102 ARV-102 is an investigational, orally bioavailable PROTAC designed to cross the blood-brain barrier and specifically target and degrade leucine-rich repeat kinase (LRRK2), a large, multidomain scaffolding kinase with GTPase activity. Increased activity and over expression of LRRK2 have been implicated in the pathogenesis of neurological diseases, including LRRK2 genetic and idiopathic Parkinson’s disease and progressive supranuclear palsy (PSP). ARV-102 is currently being evaluated in a Phase 1 clinical trial in patients with Parkinson’s disease and Arvinas plans to initiate a Phase 1b clinical trial with ARV-102 in patients with PSP, pending regulatory feedback, in the first half of 2026. About ARV-806 ARV-806 is a novel, investigational PROTAC designed to selectively target and degrade mutant Kirsten rat sarcoma (KRAS) G12D. KRAS is one of the most frequently mutated human oncogenes and G12D is the most common mutation of the KRAS protein. ARV-806 has demonstrated potent, selective degradation of KRAS G12D and robust anti-tumor activity in preclinical models. ARV-806 has the potential to address high unmet need in solid tumors, such as pancreatic, colorectal and non-small cell lung cancer, and is currently being evaluated in a Phase 1 clinical trial in patients with advanced solid tumors harboring KRAS G12D mutations. About ARV-393 ARV-393 is an investigational, orally bioavailable PROTAC designed to specifically target and degrade B-cell lymphoma 6 protein (BCL6), a transcriptional repressor and major driver of B-cell lymphomas. During B-cell development, tightly controlled BCL6 protein expression regulates >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. PROTAC-mediated degradation has the potential to address the historically undruggable nature of BCL6. ARV-393 is currently being evaluating in a Phase 1 clinical trial in patients with relapsed/refractory non-Hodgkin lymphoma. Arvinas plans to initiate enrollment of a combination cohort with glofitamab in patients with diffuse large B-cell lymphoma (DLBCL) in the ongoing Phase 1 clinical trial in mid-2026. About ARV-027 ARV-027 is an oral, peripherally restricted investigational PROTAC degrader designed to selectively target and eliminate the polyglutamine-expanded androgen receptor (polyQ-AR) in skeletal muscle. ARV-027 is a clinical candidate specifically selected for potent in-vitro reduction of cytosolic and nuclear polyQ-AR and for favorable skeletal-muscle exposure following oral administration. The polyQ-AR protein is the pathogenic driver of spinal and bulbar muscular atrophy (SBMA), a rare, X-linked, genetically defined neuromuscular disease caused by a CAG trinucleotide repeat expansion in the androgen receptor (AR) gene. SBMA leads to progressive muscle weakness, dysphagia, and functional decline, and currently has no approved disease-modifying therapies, representing a significant unmet medical need. ARV-027 is currently being evaluated in a first-in-human Phase 1 clinical trial in healthy volunteers. About ARV-6723 ARV-6723 is an investigational oral PROTAC designed to degrade hematopoietic progenitor kinase 1, or HPK1, and is Arvinas’ first clinical candidate in the immuno-oncology space. Preclinically, ARV-6723 has shown potent, selective HPK1 degradation and strong anti-tumor immune responses with superior tumor control in low- and high- immunogenic tumor models. HPK1 acts as a negative regulator in T-cell signaling. Degrading HPK1 and its scaffolding function has the potential to unleash an immune response with potent anti-tumor effects and minimum off-target toxicity. Arvinas plans to initiate a Phase 1 clinical trial of ARV-6723 in patients with advanced solid tumors, pending regulatory feedback, in mid-2026. About Vepdegestrant Vepdegestrant is an investigational, orally bioavailable PROTAC estrogen receptor degrader. In the VERITAC-2 Phase 3 study, vepdegestrant demonstrated statistically significant and clinically meaningful improvement in progression free survival compared to fulvestrant in patients with estrogen receptor positive (ER+)/human epidermal growth factor receptor 2 negative (HER2-) ESR1-mutated advanced or metastatic breast cancer previously treated with endocrine-based therapy. The U.S. Food and Drug Administration (FDA) is reviewing the filed New Drug Application (NDA) for vepdegestrant. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) action date of June 5, 2026. Vepdegestrant has also been granted Fast Track designation by the FDA, underscoring the significant unmet need in this patient population and the potential for vepdegestrant to offer a meaningful new treatment option. In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer share worldwide development costs, commercialization expenses, and profits. In September 2025, Arvinas and Pfizer announced their plan to jointly select a third party for the commercialization and potential further development of vepdegestrant. About Arvinas Arvinas (Nasdaq: ARVN) is a clinical-stage biotechnology company dedicated to improving the lives of patients suffering from debilitating and life-threatening diseases. Through its PROTAC (PROteolysis TArgeting Chimera) protein degrader platform, Arvinas is pioneering the development of protein degradation therapies designed to harness the body’s natural protein disposal system to selectively and efficiently degrade and remove disease-causing proteins. Arvinas is currently progressing multiple investigational drugs through clinical development programs, including ARV-102, targeting LRRK2 for neurodegenerative disorders; ARV-806, targeting KRAS G12D for mutated cancers, including pancreatic, colorectal, and non-small cell lung cancers; ARV-393, targeting BCL6 for relapsed/refractory non-Hodgkin Lymphoma; ARV-027, targeting the polyglutamine-expanded androgen receptor, or polyQ-AR, in skeletal muscle; and vepdegestrant, targeting the estrogen receptor for patients with locally advanced or metastatic ER+/HER2- breast cancer.
