Great Lakes Dredge & Dock (GLDD) VP Ryan Bayer Receives Award
What Happened
Ryan Bayer (VP & CAO) was granted 10,126 restricted stock units (RSUs) on May 8, 2025. The Form 4/A reports the award as an acquisition (code A); no purchase price is recorded because RSUs are awards that convert to shares on vesting. No immediate sale or cash transaction occurred.
Key Details
- Transaction date: 2025-05-08 (award of 10,126 RSUs)
- Filing: Amended Form 4 (filed 2026-03-25) correcting an administrative error in the original Form 4 filed May 12, 2025. The amendment fixes the vesting start date.
- Correct vesting start date: May 8, 2026 (was incorrectly reported as March 15, 2026 in the original filing) — see footnote.
- Price: N/A (RSU award; no cash purchase)
- Shares owned after transaction: Not specified in this filing.
- Timeliness: This is an amended filing to correct the vesting date; the amendment was filed months after the original report.
Context
RSUs are grants that convert into actual shares only as they vest; they are not open-market purchases or sales and therefore do not indicate an immediate bullish or bearish trade. The amendment here only corrects the reported vesting start date; it does not change the number of RSUs granted.
