Petterson Lasse 4/A

What Happened

• Lasse Petterson, CEO & President and a director of Great Lakes Dredge & Dock Corp. (GLDD), was granted 125,145 restricted stock units (award) on May 8, 2025. The filing shows an award (code A); no cash price is reported because this is a compensation grant rather than an open-market purchase or sale.

Key Details

• Transaction date: 2025-05-08 (reported on an amended Form 4/A filed 2026-03-25).
• Transaction type/code: Award (A) — 125,145 restricted stock units; no acquisition price (N/A).
• Vesting: Corrected vesting start date is May 8, 2026 (amendment corrects an earlier administrative error that had listed March 15, 2026).

• Filing note: This is an amendment correcting the vesting date from the original Form 4 filed May 12, 2025; the amendment does not indicate additional trades.

Context

• Restricted stock units (RSUs) are compensation grants that convert to shares only if and when they vest; they do not represent an immediate market purchase or sale. Such awards are routine forms of executive compensation and do not, by themselves, signal buying or selling intent. The amendment simply fixes an administrative reporting error about the vesting schedule.
