These are routine tax-withholding sales tied to RSU vesting, not discretionary insider selling. No trading signal. Monitor for any future discretionary Form 144 filings by officers, which would carry more weight.

Executive Summary
Two officers of Maze Therapeutics filed Form 144 notices on September 2, 2026, indicating intent to sell shares to satisfy tax withholding obligations upon RSU vesting. Courtney Phillips plans to sell 4,144 shares (~$110K) and Jason V. Coloma plans to sell 23,497 shares (~$623K). These are mandatory sell-to-cover transactions, not discretionary insider sales, and represent a negligible fraction of the company's $1.5B market cap.
