Earnings call
Q3 revenue grew 52%; TTR outlook at low end

Alnylam’s Q3 product revenue grew 52% year-over-year to approximately $1.3 billion. TTR sales are expected at the low end of $4.2 billion to $4.5 billion, while Triton-CM enrollment rose 500 patients to approximately 2,250 without changing approximately 2030 launch timing.

4 source passages
Our third quarter product revenues grew 52% year-over-year to approximately $1.3 billion, led by continued Amvutra uptake, establishing a strong foundation for our TTR franchise. For TTR product sales, based on performance to date and our expectations for Q4, we expect to land at the low end of our $4.2 billion to $4.5 billion range. As such, we are announcing today that we are amending the protocol to further increase the sample size by 500 patients to a total of 2,250 patients to address the potential risk of lower-than-expected event rates. Importantly, we do not expect this expansion to change our expected launch timeline of approximately 2030, given the speed of enrollment and the ability with more patients to accrue more events.

AI Brief

Q3 FY26 earnings call · Oct 29, 2026
Q3 FY26

TL;DR. Alnylam delivered strong Q3 product-revenue growth, positive GAAP net income, higher cash, and positive pipeline updates including expanded TRITON-CM enrollment, encouraging brezosiran data, HELIOS-B analyses, mivelsiran progress, and an upcoming cemdisiran PDUFA event. However, demand conversion is lagging expectations, 2026 TTR sales are expected at the low end of guidance, margins and operating income declined, proposed 340B and UnitedHealth policy changes create access and ordering risks, and 2027 revenue guidance was deferred.

Bullish
  • + TRITON-CM enrollment is expanding to approximately 2,250 patients while preserving expected 2030 launch timing. new
  • + Positive brezosiran Phase 1 data support a Huntington’s disease pivotal study planned for 2027. new
Bearish
  • − Management expects 2026 TTR product sales at the low end of the $4.2 billion to $4.5 billion range. new
  • − Expanded commercial engagement has not yet translated into demand growth at the anticipated pace. new
  • − UnitedHealth’s more restrictive Medicare Advantage policy could delay treatment starts for some new patients. new
  • − The company will not provide 2027 product revenue guidance at J.P. Morgan, delaying visibility on the next year’s outlook. new
