Wall Street Thinks This Biotech Stock Can Soar 45%. Here's Why Analysts Are Right.

Alnylam Pharmaceuticals has gained strong analyst support with 21 of 29 analysts rating it as buy or strong buy, with an average price target of $436 (45% upside). The company is transitioning from a clinical biotech to a profitable commercial powerhouse, with Q1 product revenue surging 121% year-over-year to $1.04 billion, driven by its ATTR franchise. The company's pipeline is expanding into mainstream markets like cardiomyopathy and hypertension, supported by a unique RNAi delivery platform that creates a competitive moat. However, the stock trades at a high valuation of 75x trailing earnings, with risks from competitive pricing pressure.
