On January 9, 2023, the Company and Pfizer Inc. ("Pfizer") provided updated guidance related to the anticipated initiation of the VERITAC-3 first-line, metastatic estrogen receptor positive/HER2 negative (ER+/HER2-) breast cancer Phase 3 study of ARV-471 in combination with IBRANCE® (palbociclib).

In the most recent analysis of data from the ongoing Phase 1b combination study of ARV-471 with palbociclib, an increase in palbociclib exposure was observed relative to historical palbociclib pharmacokinetic data.

In light of the recent data analysis, the Company and Pfizer have proposed a modification to the planned VERITAC-3 Phase 3 study and requested a meeting with the U.S. Food and Drug Administration (the "FDA") to review the proposed update to the VERITAC-3 Phase 3 study protocol for ARV-471 in combination with palbociclib to determine the optimal dose of palbociclib as part of the trial design. In the event that the FDA agrees with the proposed amendment, the Company and Pfizer expect to initiate enrollment of the VERITAC-3 Phase 3 study in the second half of 2023. The Company and Pfizer expect to provide a regulatory update after meeting with the FDA.

In the most recent analysis of data from the ongoing Phase 1b study of ARV-471 in combination with palbociclib, the following were observed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• An approximate increase of 50% in mean palbociclib exposure (i.e., pharmacokinetic area under the curve and Cmax) in the fed state was observed relative to historical palbociclib pharmacokinetic data in the fasted state.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Grade 3/4 neutropenia, a known dose-related adverse reaction associated with palbociclib, was 76% for 200 mg ARV-471 with 125 mg palbociclib (n=21).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ As per the U.S. Package Insert, (USPI) the starting dose of palbociclib for patients with HR+/HER2- metastatic breast cancer is 125 mg. As per the palbociclib USPI, a Grade ≥3 decrease in neutrophil counts was reported in 66% of patients receiving IBRANCE plus letrozole in Study 1 (PALOMA-2) and 66% of patients receiving IBRANCE plus fulvestrant in Study 2 (PALOMA-3).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ There was no increase in the rate of infection reported in the ARV-471 with palbociclib Phase 1b investigation relative to the rates reported in the registrational Phase 3 studies of palbociclib.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The neutropenia events in the ARV-471 Phase 1b study were manageable with standard dose reductions of palbociclib.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In the arm combining palbociclib with 200 mg ARV-471, one of 21 patients discontinued.

In addition to the above, the Company also provided the updated guidance set forth below related to its other programs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• VERITAC-2, a Phase 3 pivotal trial (First Subject First Visit) with ARV-471 as a second-line treatment in patients with ER+/HER2- metastatic breast cancer, is actively recruiting.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company initiated the TACTIVE-U, the Phase 1b trial with ARV-471 in combination with ribociclib and abemaciclib, in two of the combination arms in the fourth quarter of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to present data from the Phase 1b combination trial of ARV-471 with palbociclib in the second quarter of 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to initiate a Phase 3 trial with ARV-471 in the adjuvant setting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to initiate a pivotal trial for bavdegalutamide (ARV-110) for the treatment of men with metastatic castration-resistant prostate cancer in the second half of 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to report data from the Phase 1 dose escalation trial of ARV-766 for the treatment of men with metastatic castration-resistant prostate cancer in the second quarter of 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to submit an investigational new drug ("IND") application or clinical trial application ("CTA") for its BCL6 PROTAC® degrader in the second half of 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to submit an IND or CTA for its PROTAC<sup>®</sup> LRRK2 degrader in the second half of 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Company expects to have two additional programs in IND-enabling studies by the end of 2023.

3 Iterative activity PROTAC® High specificity without the requirement for strong binding PROTAC® protein degraders combine the benefits of small molecules and gene-based knockdown technologies 1. Complex Formation: Recognizing disease causing protein of interest 2. Protein Tagging: Tagging of target protein for degradation 3. Protein Destruction: Target protein is degraded by the proteasome Arvinas' proteolysis-targeting chimera (PROTAC®) degraders can: • Eliminate (rather than inhibit) disease-causing proteins • Disrupt scaffolding functions of target proteins • Bind and degrade classically "undruggable" proteins • Act iteratively (catalytically) • Be delivered orally and achieve broad tissue distribution, including across the blood-brain- barrier

PROTAC® degraders could revolutionize the treatment of patients with neurological diseases 18 We are creating PROTAC® degraders that can:  Be delivered orally  Cross the blood-brain barrier  Reach targets in "deep brain" regions  Degrade disease-causing proteins inside cells Significant potential advantages over existing modalities  Differentiate between mutant and wild-type proteins, e.g., mutant huntingtin

PROTAC®-induced LRRK2 degradation could be a disease-modifying modality for Parkinson's Disease 19 LRRK2 is a multidomain scaffolding kinase that contributes to PD (familial and idiopathic) • Parkinson's Disease (PD) is the second most common neurodegenerative disease, with a diagnosed prevalence of 2.5M in the US, EU5, and Japan • No disease-modifying therapies have been approved for PD • Familial mutations and sporadic variants (~2x increase in expression) implicate leucine-rich repeat kinase 2 (LRRK2) in PD • Human genetics and preclinical animal model data suggest that reduction of 50% of LRRK2 protein, but not kinase inhibition, may impact pathology and dysfunction in PD1 LRRK2, leucine-rich repeat kinase 2; PD, Parkinson's Disease 1 Wang, 2021, Zhao, 2017, Henderson, 2019
