This 424B5 prospectus supplement details the terms of the At-The-Market (ATM) offering, allowing Alector to sell up to $125 million in common stock. This substantial capital raise, representing approximately 46% of the company's current market capitalization and potentially diluting existing shareholders by 43.8%, comes on the heels of a highly negative Q1 2026 earnings report, which revealed a 71.5% revenue decline and the discontinuation of its nivisnebart Phase 2 program. The timing of this significant dilutive offering, immediately following such adverse operational and financial news, suggests a critical need for capital to fund ongoing operations and R&D, particularly for its next-generation pipeline built on the ABC platform. Investors should be aware of the substantial dilution and the potential overhang on the stock price as shares are sold into the market.
