Alnylam grows AMVUTTRA while lowering 2026 revenue guidance

Alnylam's growth case is supported by AMVUTTRA's strong first-line adoption, a broad pipeline, and geographic and diagnostic expansion. The main counterweight is that normalized second-line demand prompted a $200 million guidance reduction, leaving execution, pricing, payer access, and clinical outcomes as key tests.

Transcript intelligence

What changed

AMVUTTRA surpassed $1 billion in quarterly revenue and first-line starts reached about 80% of new patients. Against that progress, management lowered 2026 revenue guidance by $200 million because second-line demand normalized, while highlighting new AI collaborations, the BeOne China partnership, and additional pipeline activity.

Guidance delta

Management lowered 2026 revenue guidance by $200 million, citing normalized second-line demand, while retaining a 75% year-over-year growth trajectory.

Key takeaways

  • AMVUTTRA exceeded $1 billion in quarterly revenue, with first-line starts representing about 80% of new patients.
  • Management said the competitive backdrop improved, citing delayed generic tafamidis entry and eplontersen's failure.
  • AI collaborations, prescriber expansion, and the BeOne partnership support diagnosis, access, and geographic growth.
  • The pipeline remains central, with programs including nucresiran, ALN-6400, mivelsiran, and ALN-HTT02.

Management priorities

  • Broaden AMVUTTRA adoption through commercial efforts and community-physician outreach.
  • Advance AI-enabled diagnosis and evidence-generation initiatives.
  • Prepare for the AMVUTTRA China launch and deliver multiple 2026 pipeline readouts.

Methodology

Reported and consensus figures come from FN2's earnings event records. Market reaction and volume are calculated from daily adjusted bars around the event; abnormal move subtracts the SPY move over the same window.

Analyst target low, average, and high values are derived at request time from each named analyst's latest persisted FMP target. The current-price marker comes from FN2's persisted market snapshot. They are sell-side estimates, not an FN2 valuation or recommendation.

Transcript intelligence is a structured synthesis of the current and prior earnings-call analyses. Missing values stay missing and are never estimated.
