James Kyle Dean, Gevo's Chief Commercial Officer, was granted 158,334 restricted common shares on 2026-04-01 (award code A) at a $0.00 purchase price. As part of the vesting/settlement, 25,118 shares were withheld by the issuer to cover tax withholding obligations (code F) at an implied value of $2.40 per share, totaling $60,283.

Key Details

• Transaction dates: 2026-04-01 (grant and tax withholding); amended Form 4 filed 2026-05-22. The filing appears late relative to the typical two-business-day Form 4 deadline.
• Grant: 158,334 restricted shares granted @ $0.00 (code A).
• Withholding: 25,118 shares withheld for taxes @ $2.40 = $60,283 (code F).
• Shares owned after transaction: not specified in the information provided.
• Footnotes:
  • F1: Award vests in three equal annual installments beginning on the grant date, subject to continued service.
  • F2: Shares withheld to cover tax withholding upon vesting.
  • F3: This filing amends a prior report to correct an inadvertent error in the amount withheld for taxes.

Context
Restricted stock grants (code A) are compensation, not open-market purchases; withholding of shares for taxes (code F) is routine and not the same as a voluntary sale. The amendment indicates a correction to the previously reported withholding amount; investors should note the filing timing and that this report reflects an awarded grant with a standard vesting schedule.
