Aiyar Ram 4

What Happened
Aiyar Ram, President, Chief Executive Officer and a director of Korro Bio (KRRO), sold 15,152 shares of common stock in an open-market transaction on May 29, 2026. The weighted-average sale price was $12.98 per share, resulting in total proceeds of approximately $196,673. The filing indicates the sale was made solely to satisfy tax withholding obligations arising upon vesting/settlement of a performance stock unit, so this was a routine tax-withholding sale rather than a directional investment decision.

Context
Sales to cover tax withholding when awards vest/settle are common and typically reflect tax obligations rather than a CEO's view on the company's prospects. The filing’s footnotes clarify that the sale was tied to settlement of equity awards and that some shares are held in a trust (with a disclaimer of beneficial ownership).
