GLDD SVP David Johanson Receives 13,179-Share Award

What Happened David Johanson, Senior Vice President – Project Acquisition & Operations at Great Lakes Dredge & Dock (GLDD), was granted 13,179 shares (reported as an award/acquisition) on May 8, 2025. The filing shows no purchase price (award/compensation vehicle), so no total dollar value is reported. This Form 4/A amends the original filing to correct the vesting start date for these restricted stock units.

Key Details

  • Transaction type: Award/Grant (code A) of 13,179 shares reported as acquired on 2025-05-08. Price: N/A (compensation award).
  • Vesting: Amendment corrects vesting start date to May 8, 2026 (original Form 4 had an incorrect March 15, 2026 vesting date).
  • Filing: This is an amended Form 4 (filed 2026-03-25) correcting an administrative error in the original May 12, 2025 filing. This amendment does not report a new transaction.
  • Shares owned after transaction: Not specified in the filing.

Context Restricted stock unit (RSU) awards are a form of compensation that convert to shares upon vesting; they are not an open-market purchase or sale and so do not directly signal buying or selling intent. The amendment is administrative—correcting the vesting commencement date—and does not change the number of shares granted.
