Novartis merger vote rescheduled, close imminent
Watch: Watch for the shareholder vote on February 26 — a rubber stamp at this point — and the actual merger close on February 27. Any last-minute regulatory snag would be the only surprise, but the rescheduled timeline suggests deal mechanics are locked.
Avidity Biosciences postponed its shareholder vote from February 23 to February 26, 2026, to coordinate timing with the spin-off distribution of Atrium Therapeutics shares. The Novartis merger is now expected to close on February 27, 2026, with the stock ticker changing to "RNAM" upon the distribution. Hedge funds added RNA to their positions throughout Q4 2025, with 28 new holders — a sign institutional confidence ahead of the deal close.
The delay is purely procedural and de-risks deal execution. With both the Atrium spin-off distribution and Novartis merger closing locked into consecutive days, the structural complexity is now resolved. Hedge fund momentum into the deal suggests sophisticated money views this as a favorable outcome for RNA shareholders heading into the Novartis integration.
