AMLX stock is moving higher today after the company priced an upsized $500 million public offering of 14.09 million common shares at $35.50 per share. The underwriters also received a 30-day option to purchase up to an additional 2.11 million shares. The offering is expected to close on or about August 21 and is intended to support the company’s growth and pipeline development. The move follows a recent surge in the stock, which has risen 70.3% over the last eight sessions.

What Happened

Amylyx Pharmaceuticals announced the pricing of its public offering, which significantly outsizes the $350 million originally reported in earlier coverage. The company’s shares are trading near their 52-week high of $35.39, with the offering price at $35.50. The offering includes a greenshoe option that could bring in up to an additional $75 million in capital. This follows a series of price target upgrades from analysts, including Guggenheim, Mizuho, and BofA, who raised their targets to $55, $42, and $39 respectively. The stock has been on a strong upward trajectory, driven by both capital-raising activity and analyst optimism.

What The Data Shows

Over the past eight trading sessions, AMLX has surged from $22.67 to $38.60, a gain of 70.3%. The stock printed two fresh 52-week highs and one 52-week low on August 20. Recent insider transactions include one sell transaction totaling $539,000. The stock remains unprofitable, with a trailing twelve-month revenue decline of 100.3% and an EPS of -1.43. Despite the strong price action, the company’s market cap of $2.4 billion reflects its pre-commercial status and ongoing losses.

What To Watch

The company’s public offering is expected to close on or about August 21. Investors should monitor the final transaction details and any follow-up commentary from analysts or executives. Coverage breadth remains elevated, with 18 stories from 10 sources in the last 36 hours.
