Alnylam Shares Plunge 25% After $200 Million 2026 Sales Cut and Legal Probe

2 articles · Updated · pluang.com · Aug 28

Summary

  • Alnylam shares sank about 25%, or $81.14 a share, after the company cut its 2026 sales outlook and disclosed a legal probe.
  • The forecast reduction totaled roughly $200 million and was tied to slower demand for Alnylam's transthyretin, or TTR, products.
  • The selloff stood out against a generally strong biotech sector, underscoring how sharply investors reacted to the weaker demand outlook and added legal overhang.
  • The drop leaves Alnylam facing pressure on both growth expectations and investor confidence as it navigates softer product momentum and the investigation.
