Extended-hours trading shows ALNY at $217.95, down 6.22% from the regular close of $232.40. The drop likely reflects the GAAP EPS headline being inflated by a one-time $1.87B tax benefit, while non-GAAP operating income actually declined 11% YoY and collaboration revenue collapsed 80%.

The 6% extended-hours selloff reveals the market is looking past the GAAP headline — the real story is declining operating income and an 80% collaboration revenue drop, even as AMVUTTRA's ATTR-CM launch accelerates.

Alnylam's AMVUTTRA franchise is scaling rapidly in the ATTR-CM market, competing against Pfizer's tafamidis. The TRITON-CM enrollment expansion signals confidence in nucresiran as a next-gen follow-on, while the brezosiran Huntington's data and mivelsiran Alzheimer's progress highlight RNAi platform breadth beyond TTR.

GAAP net income was overwhelmingly driven by a $1.87B income tax benefit — stripping that out, non-GAAP operating income fell 11% YoY. Collaboration revenue dropped 80% YoY due to a tough comp from a $300M Roche milestone in Q3 2025, and ONPATTRO continues to decline (-50% YoY).
