Gellert John M 4

What Happened

• John M. Gellert, President, CEO and a director of SEACOR Marine Holdings, had one tranche of 9,562 performance restricted stock units (PRSUs) convert into 9,562 shares on 2026-03-07.
• To satisfy tax withholding, 4,193 of those shares were withheld/disposed at $7.31 per share for a total withholding value of $30,651. Net shares issued to him from this tranche: 5,369.
• The filing shows the derivative instrument was converted (transaction code M) and the withholding/tax payment was reported as a disposition (transaction code F). This was a compensation vesting/conversion event rather than an open-market buy or sell.

Key Details

• Transaction date: 2026-03-07; Form 4 filed: 2026-03-10 (timely).
• Conversion: 9,562 PRSUs -> 9,562 common shares (reported as M, $0.00 for derivative disposition/conversion).
• Tax withholding: 4,193 shares withheld @ $7.31 = $30,651 (reported as F).
• Net new shares to insider from this tranche: 5,369.
• Relevant footnotes: PRSUs convert one-for-one into common stock (F1); this was one tranche of the 2023 PRSU grant that met performance/service conditions and vested (F6); other footnotes note indirect ownership via related entities and disclaimers (F2–F5).
• No indication of a 10b5-1 plan or late filing in the report.

Context

• This was a vesting/conversion of performance RSUs after a performance goal was met — a routine compensation event. Shares were not sold on the open market; instead a portion was withheld to cover tax obligations (a common cashless-withholding method).
• The 2023 PRSU award consisted of five tranches tied to stock-price goals; only this tranche vested and the remaining 2023 PRSUs were forfeited per the footnote.
