Alnylam Q3 2026 earnings beat, expands nucresiran trial and reaffirms FY‑26 outlook

Alnylam Pharmaceuticals reported third‑quarter 2026 revenue of $1.46 billion, up 17% year‑over‑year, and GAAP net income of $2.2 billion. AMVUTTRA sales rose 65% to $1.13 billion, driving a 59% increase in TTR franchise revenue. Management expanded the Phase 3 TRITON‑CM nucresiran enrollment to about 2,250 patients and reaffirmed its full‑year 2026 guidance, but shares fell roughly 17%‑19% after the release.

The company’s reaffirmed FY‑26 product‑revenue guidance of $4.2‑$4.5 billion (the low end of the range) sets expectations for TTR sales growth and may pressure the stock, as noted by the market reaction (share decline of ~17%‑19%). (source 10) The expanded nucresiran trial signals continued investment in the pipeline, but also adds execution risk that analysts highlight (source 9).
