NEW HAVEN, Conn., Nov. 05, 2025 -- Arvinas, Inc. (Nasdaq: ARVN), a clinical-stage biotechnology company creating a new class of drugs based on targeted protein degradation, today reported financial results for the third quarter ended September 30, 2025, and provided a corporate update.

"The third quarter was marked by meaningful pipeline progress and strategic decisions aimed at positioning the company for sustained long-term growth and value creation," said John Houston, Ph.D., Chairperson, Chief Executive Officer, and President of Arvinas. "We have entered the beginning of a data-rich period with multiple readouts from our early-stage clinical programs. We also presented the first preclinical data from ARV-027, our promising new clinical candidate that targets the root cause of spinal bulbar muscular atrophy. Looking ahead, our mission is clear: to drive innovation across our PROTAC degrader portfolio and deliver transformative therapies to patients."

**3Q 2025 Business Highlights and Recent Developments** 

**ARV-102: Oral PROTAC LRRK2 degrader**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Presented positive data from two Phase 1 clinical trials in an oral session at the International Congress of Parkinson's Disease and Movement Disorders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In single ascending and multiple ascending doses in healthy volunteers, ARV-102 was generally well tolerated at single doses up to 200 mg and multiple daily doses up to 80 mg, with no discontinuations due to adverse events (AEs) or serious adverse events (SAEs) observed in the study population. ARV-102 showed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increased exposure in a dose-dependent manner in plasma and cerebrospinal fluid (CSF), the latter indicating brain penetration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Greater than 90% reductions of LRRK2 protein in peripheral blood mononuclear cells (PBMCs) and greater than 50% reductions in CSF (repeated daily doses ≥20 mg).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reduced plasma concentrations of phospho-Rab10T73 and urine concentrations of bis(monoacylglycerol)phosphate (BMP), a sensitive biomarker for modulation of the lysosomal pathway downstream of LRRK2 (repeated daily doses).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant decreases in lysosomal pathway markers and neuroinflammatory microglial markers previously shown to be elevated in patients with Parkinson's disease harboring LRRK2 variants as measured by unbiased proteomic analysis of CSF (ARV-102 80 mg once daily for 14 days).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To the Company's knowledge, this is the first time an investigational LRRK2 therapy has, at 14 days in healthy volunteers, shown effects on distal pathway biomarkers in CSF that are elevated in patients with Parkinson's disease.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the ongoing single ascending dose trial in patients with Parkinson' disease, single doses of ARV-102 (50 mg or 200 mg) were well tolerated with only mild treatment-related AEs including headache, diarrhea, and nausea; no SAEs occurred. ARV-102 showed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Dose-dependent increases in exposure in both plasma and CSF, the latter indicating brain penetration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Median PBMC LRRK2 protein reductions of 86% with the 50 mg dose and 97% with the 200 mg dose.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Initiated the multiple dose cohort of the Phase 1 clinical trial in patients with Parkinson's disease.

**ARV-393: Oral PROTAC BCL6 degrader**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced there have been multiple responses in early cohorts of both B-and T-cell lymphomas in the first-in-human Phase 1 trial in patients with non-Hodgkin lymphoma (NHL). The anticipated effective exposure level has not been achieved, and dose escalation in the trial is ongoing (ClinicalTrials.gov Identifier: NCT06393738).

**ARV-806: Novel PROTAC KRAS G12D degrader** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Presented new preclinical data at AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics highlighting its high potency and clear differentiation from both KRAS inhibitors and degraders currently in the clinic while also demonstrating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Dose-dependent, selective, robust anti-tumor activity, with regressions across preclinical models of KRAS G12D-mutant cancers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In vitro potency approximately 25 times greater than KRAS inhibitors and 40 times greater than the leading clinical-stage degrader.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Degradation >90% for 7 days after single dose and significant efficacy in models of pancreatic, colorectal, and lung cancer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Initiated Phase 1 trial evaluating ARV-806 in patients with solid tumors harboring KRAS G12D mutations (ClinicalTrials.gov Identifier: NCT07023731).

**ARV-027: Oral PROTAC polyQ-AR degrader**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Dose-dependent degradation of polyQ-AR in mouse muscle that was sustained for more than 24 hours (single oral dose).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

**Vepdegestrant: Oral PROTAC ER degrader**

*As part of Arvinas' global collaboration with Pfizer, the companies:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced the U.S. Food and Drug Administration (FDA) acceptance of the New Drug Application (NDA) for vepdegestrant for the treatment of estrogen receptor 1 (ESR1) mutated, estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer previously treated with endocrine-based therapy. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) action date of June 5, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced agreement with Pfizer to jointly select a third party for the commercialization and potential further development of vepdegestrant, with the goal of rapidly bringing it to patients, if approved.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Presented new patient-reported outcomes data from the Phase 3 VERITAC-2 clinical trial and Phase 2 results from the TACTIVE-N clinical trial at the 2025 European Society for Medical Oncology Congress:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ Patient-reported outcomes data from the VERITAC-2 clinical trial highlighted that patients with ESR1-mutated disease treated with vepdegestrant reported a statistically significant

------

delay in deterioration of overall quality of life, pain, and multiple functioning domains versus those who received fulvestrant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ The TACTIVE-N clinical trial, which evaluated neoadjuvant vepdegestrant in postmenopausal women with ER+/HER2– localized breast cancer, showed that neoadjuvant vepdegestrant demonstrated biological and clinical activity in this treatment-naïve, predominantly ESR1 wild-type population of postmenopausal women with ER+/HER2- localized breast cancer.

**Financial Guidance** 

Based on its current operating plan, Arvinas believes its cash, cash equivalents, and marketable securities as of September 30, 2025, is sufficient to fund planned operating expenses and capital expenditure requirements into the second half of 2028.

**Third Quarter Financial Results**

**Cash, Cash Equivalents, and Marketable Securities Position:** As of September 30, 2025, cash, cash equivalents, and marketable securities were $787.6 million as compared with $1,039.4 million as of December 31, 2024. The decrease in cash, cash equivalents, and marketable securities of $251.8 million for

------

the nine months ended September 30, 2025, was primarily related to cash used in operations of $233.1 million, repurchases of our common shares under our Stock Repurchase Program of $17.8 million, the purchase of lab equipment and leasehold improvements of $1.7 million.

**Research and Development Expenses:** Generally Accepted Accounting Principles (GAAP) Research and development (R&D) expenses were $64.7 million for the quarter ended September 30, 2025, as compared with $86.9 million for the quarter ended September 30, 2024. The decrease in R&D expenses of $22.2 million for the quarter was primarily due to a decrease in external expenses of $7.4 million and a decrease in compensation and related personnel expenses of $14.2 million, which are not allocated by program. External expenses include program-specific expenses, which decreased by $6.5 million, primarily driven by decreases in our vepdegestrant (ARV-471), luxdegalutamide (ARV-766), and bavdegalutamide (ARV-110) programs of $5.4 million, $4.7 million, and $2.4 million, respectively, partially offset by increases in ARV-806 of $4.3 million.

Non-GAAP R&D expenses were $56.9 million for the quarter ended September 30, 2025, as compared with $73.2 million for the quarter ended September 30, 2024, excluding $0.4 million of restructuring expense for the quarter ended September 30, 2025, and $7.4 million and $13.7 million of non-cash stock-based compensation expense for the quarters ended September 30, 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 $21.0 million for the quarter ended September 30, 2025, as compared with $75.8 million for the quarter ended September 30, 2024. The decrease in G&A expenses of $54.8 million for the quarter was primarily due to a decrease of $43.4 million for the termination of our laboratory and office space lease with 101 College Street LLC in August 2024, a decrease in personnel and infrastructure related costs of $7.3 million, and professional fees of $3.6 million.

Non-GAAP G&A expenses were $14.6 million for the quarter ended September 30, 2025, as compared with $64.8 million for the quarter ended September 30, 2024, excluding $0.6 million of restructuring related reversal of previously recognized expense for the quarter ended September 30, 2025, and $7.0 million and $11.0 million of non-cash stock-based compensation expenses for the quarter ended September 30, 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 $41.9 million for the quarter ended September 30, 2025, as compared with $102.4 million for the quarter ended September 30, 2024. Revenue for the quarter is related to the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer and the collaboration and license agreement with Pfizer. The decrease of $60.5 million was primarily due to $76.7 million of decreased revenue from the Novartis License Agreement and the Novartis Asset Agreement, both of which were entered into during the three months ended June 30, 2024, and were completed by December 31, 2024, as the technology transfer of our ongoing and planned clinical trials of luxdegalutamide (ARV-766) were transitioned to Novartis. Revenue from the Vepdegestrant (ARV-471) Collaboration Agreement with Pfizer decreased by $3.1 million and revenue from the Bayer Collaboration Agreement decreased by $0.5 million as a result of the termination of the Bayer Collaboration Agreement in August 2024. The overall decrease was offset by the recognition of $20.0 million for achievement of a development milestone pursuant to the terms of the Novartis License Agreement.

**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-393, targeting BCL6 for relapsed/refractory non-Hodgkin Lymphoma; ARV-806, targeting KRAS G12D for mutated cancers, including pancreatic and colorectal cancers; and vepdegestrant, targeting the estrogen receptor for patients with locally advanced or metastatic ER+/HER2- breast cancer. Arvinas is headquartered in New Haven, Connecticut. For more information about Arvinas, visit www.arvinas.com and connect on **LinkedIn** and **X**.

**About ARV-102** 

ARV-102 is an investigational, orally bioavailable and brain-penetrant PROTAC designed to 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-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 evaluated in a Phase 1 clinical trial in patients with relapsed/refractory non-Hodgkin lymphoma.

**About ARV-806** 

ARV806 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-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. Arvinas plans to initiate a first-in-human Phase 1 clinical trial of ARV-027 in healthy volunteers, pending regulatory feedback, in 2026.

**About ARV-6723**

ARV-6723 is an oral investigational 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 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) has filed the New Drug Application (NDA) for vepdegestrant. 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.

**Non-GAAP Financial Information**

The results presented in this press release include both Generally Accepted Accounting Principles (GAAP) information and non-GAAP information. As used in this release, non-GAAP research and development ("R&D") expense is defined by Arvinas as GAAP R&D expense excluding restructuring and stock-based compensation expense, and non-GAAP general and administrative ("G&A") expense is defined by Arvinas as GAAP G&A expense excluding restructuring and stock-based compensation expense. Arvinas uses these non-GAAP financial measures to evaluate Arvinas' ongoing operations and for internal planning and forecasting purposes. Arvinas believes 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 Arvinas' 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 Arvinas' 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 Arvinas' business
