|---|---|---|---|---|
| 2026-02-18 | Clinical data update | Positive | +0.1% | NEJM publication of Phase 1/2 MARINA trial results for del-desiran in DM1. |

24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent Avidity headlines tied to the Novartis deal, spin-off, and clinical progress have all seen modestly positive next-day price reactions, suggesting news flow has generally reinforced a deal-anchored valuation.
Over the last few months, Avidity has progressed both its strategic and clinical story. On Nov 10, 2025, it announced a merger agreement with Novartis valuing the company at about $12 billion. Subsequent updates covered a managed access program for del-zota and NEJM publication of Phase 1/2 MARINA® data, alongside the spin-off record-date announcement. Each event saw small positive price moves, so this meeting-adjournment step fits into an ongoing, largely supportive news sequence around the merger and spin-off.
