Q2 FY26 earnings call · Jul 30, 2026
Q2 FY26

TL;DR. Alnylam reported Q2 2026 total net product revenues of $1,172 million (74% growth), with TTR revenues surpassing $1 billion for the first time, driven by Amvutra demand. The company lowered full-year 2026 TTR net product revenue guidance to $4,200–$4,500 million (from $4,400–$4,700 million) due to normalization of second-line demand, while raising collaboration and royalty revenue guidance by $150 million at the midpoint to $575–$625 million.

  • + Raised full-year 2026 collaboration and royalty revenue guidance by $150 million at midpoint to $575–$625 million
  • + Non-GAAP operating income more than tripled year-over-year to $318 million
