On August 3, 2026, Alumis Inc. Chief Medical Officer Jorn Drappa executed a Form 4-reported sale of 2,447 shares of Alumis Inc. common stock at a weighted-average price of approximately $26.37 per share, for proceeds of about $64,500, leaving him with beneficial ownership of 56,892 shares. The transaction was coded as a sale but was carried out under the issuer’s mandatory sell-to-cover policy to satisfy tax obligations arising from the vesting and settlement of previously granted restricted stock units, and therefore did not represent a discretionary open-market sale by the insider. After this transaction, Drappa continues to hold a meaningful equity position in Alumis Inc., with the value of his remaining holdings estimated at roughly $1.5 million based on the reported transaction price.
