Alnylam Q2 EPS Beat But 2026 Guidance Cut and Nucrisiran Uncertainty

Jul 30, 2026, 2:57 PM EDT1 sourcesAI-analyzed
Why it may matterVerify against the original reporting

Strong guidance reduction combined with a revenue miss triggered a sharp share decline to a new 52-week low; even with an EPS beat, the market focuses on slower growth in ATTR-CM and execution risk for nucrisiran, a difficult near-term sentiment shift seen in similar biotech earnings where guidance cuts negate upside from a beat.

AI summary

What happened, with direct paths to the underlying reporting

Alnylam beat Q2 EPS estimates but missed revenue, trimming 2026 TTR sales guidance amid ATTR-CM market normalization. Amvuttra led product revenue; Onpattro contributions were modest, and nucrisiran progresses remain a key uncertainty. The stock fell to a 52-week low, signaling near-term downside unless trial data renews confidence.

  • Q2 adjusted EPS $1.84, beating consensus $1.55.
  • Sales $1.291B, up 67% YoY, but below $1.323B est.
  • Amvuttra $1,012m and Onpattro $18m in global net product revenues.
  • 2026 TTR sales guidance cut to $5.275B-$5.725B (from $5.30B-$5.80B).
  • Shares down ~29%, hitting 52-week low on guidance cut.
