Rossmiller Gregory Scott 4

What Happened

• Gregory Scott Rossmiller, SVP and CAO of SEACOR Marine Holdings, was granted two awards on Feb 27, 2026: 34,215 restricted shares (restricted stock award) and 16,420 Performance Restricted Stock Units (PRSUs). Both grants were reported at $0.00 per share (compensation awards), for a combined 50,635 units.

Key Details

• Transaction date: February 27, 2026; reported on Form 4 filed March 2, 2026 (appears to be a timely filing).
• Grant prices: $0.00 per share for both the restricted stock and the PRSUs.
• Shares owned after transaction: not disclosed in this filing.
• Vesting/settlement notes:
  • Restricted stock (34,215 shares) will lapse (vest) in five equal annual installments beginning March 4, 2027 and ending March 4, 2031. (Footnote F1)
  • PRSUs (16,420) are contingent rights to receive one share per PRSU only if both performance and service conditions are met. (Footnote F2)
  • PRSUs are divided into five equal tranches, each earned only if the closing stock price meets the tranche threshold for 60 consecutive trading days during the three-year performance period after grant; tranche thresholds are $7.67, $8.52, $9.38, $10.23 and $11.08. Any earned PRSUs will not be settled until the third anniversary of the grant date and remain subject to service-based vesting. (Footnote F3)

Context

• These are compensation awards (not open-market purchases or sales). The restricted stock provides time-based retention; the PRSUs are performance-based and will convert to shares only if specific stock-price hurdles and service requirements are met. The reported $0 grant price reflects that these are stock awards, not cash purchases; the eventual value to the insider depends on future stock performance and vesting/settlement conditions.
