Investor sentiment has been swayed by large revenue and EPS beats versus consensus as well as guidance raises. Additionally, external factors such as pricing pressure in healthcare markets, reimbursement approvals, and competition from both established pharma firms and emerging RNAi players shape the stock’s price trajectory.

In the most recent quarter, Alnylam reported substantial revenue growth, with Q3 2025 revenue reaching $1.25 billion, a significant 149% increase year-over-year, and product revenues rising 103%. The success was attributed especially to the TTR (transthyretin-mediated amyloidosis) franchise, led by Amvuttra, which saw accelerated adoption thanks to label expansion and quarterly dosing advantages. The company also raised its 2025 revenue guidance multiple times, now projecting up to $3.05 billion, reflecting analyst optimism towards continued sales growth. However, gross margins slipped slightly, and R&D and SG&A expenses increased as Alnylam invested heavily in its product pipeline. Notably, the company faces a US Attorney subpoena related to price reporting practices, a potential regulatory headwind, though it maintains a robust $2.7 billion cash position to support operations and development.

Looking ahead to the next quarter, expectations are for continued strong performance in the TTR franchise, with Amvuttra taking further market share from Onpattro as patients transition to the more convenient therapy. Revenue is anticipated to rise toward the higher end of the updated guidance, especially if the FDA expands Amvuttra’s indication to ATTR-CM by March 2025. The launch and expansion of pipeline assets like zilebesiran for hypertension and mivelsiran for Alzheimer's will likely gain momentum, especially if key late-stage trial data are positive. Analysts predict ongoing global expansion will help diversify revenues beyond the US. However, increased scrutiny on pricing, operational spending, and potential regulatory findings could create volatility.
