Alnylam cuts 2026 TTR sales outlook as second-line Amvuttra demand normalizes; shares drop 29.27%
Alnylam's Q2 beat on adjusted EPS was outweighed by a revenue miss and a cut to 2026 TTR product sales guidance as second-line ATTR-CM demand normalized after earlier pent-up uptake. The guidance reduction, alongside heightened sensitivity around ATTR-CM development timelines, triggered a sharp drawdown in ALNY, signaling deteriorating near-term sentiment toward the name and potentially pressuring risk appetite across similar biotech launch stories.
