What Happened
Matthew Wein, General Counsel, Compliance Officer and Corporate Secretary of Metagenomi Therapeutics, sold 358 shares of common stock on 2026-09-08 at $1.16 per share, bringing gross proceeds of about $415. This was a sale (disposition) and the filing shows the sale was an automatic tax-withholding transaction tied to RSU vesting rather than a voluntary market trade.

Key Details

• Transaction date and price: 2026-09-08, 358 shares at $1.16 each.
• Total proceeds reported: approximately $415.
• Shares owned after the transaction: not specified in the filing.
• Footnote: The shares were automatically sold to satisfy the reporting person’s tax withholding obligations upon vesting of restricted stock units granted April 1, 2024 and April 1, 2025; this was not a volitional trade (F1).
• Filing date: 2026-09-10; reported two days after the trade date (appears to be filed within the typical 2-business-day window).

Context
Automatic sell-to-cover transactions for tax withholding on RSU vesting are routine and do not necessarily signal insider sentiment about the company. Given the small dollar amount ($415), this transaction reflects withholding mechanics rather than a meaningful investment decision.
