Graham Corp (GHM) CFO Christopher Thome Receives RSUs; 407 Shares Withheld

What Happened

Christopher J. Thome, Vice President–Finance and CFO of Graham Corporation (GHM), received a grant of 1,408 restricted stock units (RSUs) on 2026-06-01. On 2026-06-02, RSUs converted/exercised into 1,099 shares of common stock. To satisfy tax withholding, 407 shares were withheld at $106.11 per share, totaling $43,187. The conversion/award transactions are not market purchases or open-market sales of existing shares; they reflect RSU vesting and the routine withholding of shares to cover taxes.
