Form 144 — notice of proposed sale of securities
Actionable Insight • Neutral

This is a routine equity-compensation-related sale by an officer with negligible market impact. No actionable trading signal — monitor for any subsequent Form 4 filings to confirm the sale was executed, but the filing itself is not a material event.

Executive Summary

Douglas Earl Martin, an officer of Allogene Therapeutics, filed a Form 144 notice of intent to sell 29,697 shares of common stock, with an approximate market value of $62,958. The shares were acquired via vesting of restricted stock units on August 20, 2026, under the issuer's equity compensation plan. This is a routine insider sale tied to equity compensation vesting, not a discretionary open-market sale, and the dollar amount is small relative to the company's $726M market cap, making the filing low-impact.
