Alector, Inc. reported third-quarter 2026 collaboration revenue of $162.9 million, versus $3.3 million a year earlier, and net income of $124.6 million, versus a $34.7 million net loss. The revenue increase primarily reflected recognition of remaining deferred revenue under its GSK collaboration after GSK’s termination notice and the extinguishment of remaining performance obligations.
Alector granted Genentech exclusive global rights to develop and commercialize AL050; Alector received a $100 million upfront payment and is eligible for up to an additional $1.17 billion in milestone payments plus tiered royalties. Alector completed an underwritten offering of 36,600,000 shares at $2.05 each for approximately $75.0 million in gross proceeds.

Alector, Inc. (ALEC) priced an underwritten offering of 36,600,000 common shares at $2.05 per share; Alector is selling all of the shares. Gross proceeds are expected to be $75,030,000.00 before underwriting discounts and commissions and other offering expenses payable by the company. The offer price represents an approximately 7.3% premium over the October 15, 2026 closing price.
The offering is expected to close October 19, 2026, subject to customary closing conditions. Alector anticipates using net proceeds for general corporate purposes, which may include research, development and manufacturing of product candidates, working capital, capital expenditures, other corporate expenses, and acquisitions or strategic transactions involving complementary products, technologies or businesses. TCGX, BVF Partners, ADAR1 Capital Management and Deep Track Capital are among participating new and existing investors. Morgan Stanley & Co. LLC and BTIG, LLC are joint lead book-running managers. The offering is under Alector’s effective Form S-3 registration statement.
Alector, Inc. approved an option repricing effective October 13, 2026, setting the exercise price for eligible options at $1.87 per share. It generally covered options granted to current employees under the 2019 Equity Incentive Plan or 2017 Stock Option and Grant Plan, held by continuing employees and priced above $1.87. Approximately 4.05 million shares underlie all repriced options. These include options for 2,421,197 shares held by Arnon Rosenthal, Ph.D., Co-founder and Chief Executive Officer (original exercise prices of $6.48–$23.70), and 87,385 shares held by Grace Wong-Sarad, Chief Accounting Officer and principal accounting officer (original exercise prices of $9.46–$23.70).
An employee exercising a repriced option before the Retention Period ends must pay its original exercise price. The period ends at the earliest of one year after the effective date, a Change in Control, or the option holder’s death or Disability. The repricing does not change option expiration dates, service-based vesting criteria, or the number of underlying shares.
