Arvinas, Inc.: Q1 FY2026 earnings call

What management said about Q1 FY2026, from the documents filed with the SEC on 12 May 2026: press release. Guidance figures: 2 new, 5 kept. The quarter’s numbers.

Key takeaways

  • First FDA-approved PROTAC: The FDA approved VEPPANU (vepdegestrant) as a monotherapy for ESR1-mutated, ER+/HER2- advanced or metastatic breast cancer after at least one line of endocrine therapy. The company described it as the first PROTAC the FDA has approved. Source
  • Rigel licence for global rights: Under the Pfizer collaboration, the companies licensed exclusive global development, manufacturing and commercialization rights for VEPPANU to Rigel. Closing is subject to regulatory waiting-period conditions. Source
  • Revenue fell on Pfizer program: Revenue was $15.6 million, against $188.8 million a year earlier. Management attributed the decline to changes in program cost estimates recognized in 2025 after two Phase 3 trials were removed from the plan. Source
  • R&D spend fell sharply: GAAP R&D expenses were $60.3 million, against $90.8 million a year earlier. Management attributed the decrease mainly to lower compensation and related personnel expenses. Source
  • Cash position down $70.5 million: Cash, cash equivalents and marketable securities were $614.9 million at March 31, 2026, down from $685.4 million at December 31, 2025. Cash used in operations was the main driver. Source
  • ARV-102 Parkinson's biomarkers reduced: Phase 1 data for ARV-102 showed reductions in endolysosomal and neuroinflammatory biomarkers, with dose-dependent CSF exposure increases indicating brain penetration. No serious adverse events were reported after multiple doses. Source

“The approval of VEPPANU is a defining achievement for Arvinas and reflects the culmination of more than a decade of focused work to translate our PROTAC science into our first approved therapy,”

Randy Teel, Ph.D., President and Chief Executive Officer at Arvinas

What changed from last quarter

  • New: VEPPANU (vepdegestrant) received FDA approval for ESR1-mutated, ER+/HER2- advanced or metastatic breast cancer after at least one line of endocrine therapy. The prior release showed the FDA review with a June 5, 2026 action date. Source
  • New: Under the Pfizer collaboration, the companies entered into a license agreement with Rigel Pharmaceuticals for exclusive global development, manufacturing and commercialization rights to VEPPANU. The prior release had described a plan to select a third-party partner. Source
  • New guidance: ARV-027 single-ascending dose data are now guided for 2H26. The prior release did not give this timing. Source

VEPPANU approval and Rigel licence

  • First FDA-approved PROTAC: The FDA approved VEPPANU (vepdegestrant) as a monotherapy for ESR1-mutated, ER+/HER2- advanced or metastatic breast cancer after at least one line of endocrine therapy. The company described it as the first PROTAC the FDA has approved. Source
  • Rigel licence for global rights: Under the Pfizer collaboration, the companies licensed exclusive global development, manufacturing and commercialization rights for VEPPANU to Rigel. Closing is subject to regulatory waiting-period conditions. Source
  • NCCN guideline listing added: On May 8, 2026, the NCCN added VEPPANU to its breast cancer guidelines as a Category 2A option for the indicated patients. Source

Revenue and net loss

  • Revenue fell on Pfizer program: Revenue was $15.6 million, against $188.8 million a year earlier. Management attributed the decline to changes in program cost estimates recognized in 2025 after two Phase 3 trials were removed from the plan. Source
  • Net loss and per-share loss: Net loss was $57.6 million, or $0.90 per diluted share, against net income of $82.9 million, or $1.14 per diluted share, a year earlier. Loss from operations was $63.8 million, against income of $71.4 million. Source

“As we move through the remainder of the year, our focus is on delivering key data and clinical milestones that we believe will further validate our approach and clearly distinguish our programs in an increasingly competitive environment.”

Randy Teel, Ph.D., President and Chief Executive Officer at Arvinas

Operating costs

  • R&D spend fell sharply: GAAP R&D expenses were $60.3 million, against $90.8 million a year earlier. Management attributed the decrease mainly to lower compensation and related personnel expenses. Source
  • Vepdegestrant spend down, ARV-806 up: Program-specific external expenses fell $9.5 million. The vepdegestrant program spend decreased $15.2 million, partly offset by a $5.6 million increase in the ARV-806 program. Source
  • G&A fell on lower professional fees: GAAP G&A expenses were $19.1 million, against $26.6 million a year earlier. Management attributed the decrease mainly to lower professional fees. Source

Cash and balance sheet

  • Cash position down $70.5 million: Cash, cash equivalents and marketable securities were $614.9 million at March 31, 2026, down from $685.4 million at December 31, 2025. Cash used in operations was the main driver. Source
  • Small capital spending and securities losses: Purchases of lab equipment and leasehold improvements were $1.3 million in the quarter. Unrealized losses on marketable securities were $1.6 million. Source

Pipeline progress

  • ARV-102 Parkinson's biomarkers reduced: Phase 1 data for ARV-102 showed reductions in endolysosomal and neuroinflammatory biomarkers, with dose-dependent CSF exposure increases indicating brain penetration. No serious adverse events were reported after multiple doses. Source
  • ARV-393 combination trial started: A Phase 1 combination trial of ARV-393 with glofitamab started in DLBCL. Dose escalation in the non-Hodgkin's lymphoma trial continued, with multiple responses in early cohorts at doses below the predicted effective exposure level. Source
  • ARV-806 dose escalation completed: Dose escalation enrollment is complete in the ARV-806 Phase 1 trial in patients with KRAS G12D-mutated solid tumors. Source
  • ARV-027 first-in-human dosing: Dosing started in the first-in-human Phase 1 trial of ARV-027 in healthy volunteers. Preclinical SBMA mouse data showed polyQ-AR degradation in muscle with functional improvement. Source
  • ARV-6723 preclinical activity shown: Preclinical data for ARV-6723, an HPK1 degrader, showed single-agent antitumor activity in syngeneic models. The company reported greater preclinical activity than an HPK1 inhibitor or an anti-PD-1 antibody. Source
  • Pan-KRAS degrader preclinical data: Preclinical data for a novel pan-KRAS degrader showed greater tumor growth inhibition than a pan-RAS (ON) inhibitor in a KRAS G13D model, and robust efficacy in pancreatic, colorectal and lung models. Source

Corporate leadership

  • Teel leads as CEO: Randy Teel, Ph.D., is President, Chief Executive Officer and Director, succeeding John Houston, Ph.D., who retired and remains on the Board under a consulting agreement. Briggs Morrison, M.D., chairs the Board. Source

Coming up, as management said on 12 May 2026

  • Rigel closing awaits antitrust clearance: Closing of the VEPPANU licence to Rigel is pending consents or approvals, including expiry or termination of the Hart-Scott-Rodino waiting period. Source
  • ARV-806 expansion cohort enrollment: Enrollment in the dose expansion cohort of the ARV-806 Phase 1 trial is to start, in patients with KRAS G12D-mutated solid tumors. Source
  • ARV-393 combination cohort enrollment: Enrollment of the ARV-393 plus glofitamab combination cohort in DLBCL continues in the ongoing Phase 1 trial. Source
  • ARV-027 healthy volunteer enrollment: Enrollment continues in the ARV-027 Phase 1 healthy volunteer trial. Source
