# Alector reprices ~4.05M underwater options to $1.87; CEO's 2.42M options included

## Summary
- Board approved the repricing on Oct 13, 2026, setting a new exercise price of $1.87 per share, the closing price that day, versus original strikes of $6.48 to $33.11.
- About 4.05 million shares underlie all repriced options; CEO and co-founder Arnon Rosenthal held 2,421,197 repriced options with original prices of $6.48 to $23.70.
- Chief Accounting Officer Grace Wong-Sarad had 87,385 options repriced, originally struck at $9.46 to $23.70 per share.
- Exercising before the Retention Period ends requires paying the original strike; the period ends at the earliest of one year, a change in control, or death/disability.
- Share counts, expiration dates and vesting are unchanged; Alector says repricing avoids dilution from new grants and added cash compensation costs.
