• Novartis Merger & Spin-Off Details Confirmed

  The annual report provides comprehensive details on the definitive merger agreement with Novartis AG from October 25, 2025, where Avidity will be acquired for $72.00 per share. Concurrently, Avidity will spin off its early-stage precision cardiology programs into Atrium Therapeutics, Inc. (SpinCo), with Avidity shareholders receiving one share of SpinCo Common Stock for every ten shares of Avidity common stock held. The merger is expected to close in the first half of 2026.

• Strong Clinical Pipeline Progress

  Avidity reported significant advancements across its three lead RNA therapeutic programs: del-zota (DMD44) has a BLA planned for accelerated approval in 2026 and received Breakthrough Therapy designation; del-desiran (DM1) has its Phase 3 HARBOR trial fully enrolled with 54-week data expected in H2 2026; and del-brax (FSHD) received FDA alignment on approval pathways and showed positive Phase 1/2 data, with topline biomarker data expected in Q2 2026.

• Substantial Capital Raise Bolsters Liquidity

  In 2025, the company secured approximately $836.9 million in net proceeds from public offerings and at-the-market (ATM) sales, significantly increasing its cash, cash equivalents, and marketable securities to $1.7 billion as of December 31, 2025. This financing provides substantial runway for ongoing operations and development.

• Significant Manufacturing Commitment for Commercialization

  Avidity entered into a manufacturing services agreement with Lonza LTD on August 1, 2025, committing to minimum purchase obligations of approximately $621.6 million from 2026 to 2028. This indicates a strategic move towards commercial-scale manufacturing for its product candidates.

This 10-K is a critical update, providing the definitive financial and operational context for the previously announced, thesis-altering merger with Novartis and the spin-off of Atrium Therapeutics. Shareholders will receive $72.00 per share in cash from the merger and retain exposure to the early-stage cardiology assets through SpinCo shares. The report highlights significant clinical advancements across Avidity's three lead RNA therapeutic programs, including a clear path to BLA submission for del-zota and fully enrolled Phase 3 trials for del-desiran and del-brax. These clinical milestones, combined with successful capital raises totaling over $800 million in 2025, provide substantial liquidity and de-risk future development. The $621.6 million manufacturing commitment further signals the company's progression towards commercialization. While net losses increased significantly, this is typical for a biotech advancing multiple late-stage programs and is offset by the strong financing and strategic corporate actions. The remediation of the material weakness in internal controls is a positive for corporate governance. Investors should monitor the final closing of the merger and the upcoming clinical data readouts.
