Great Lakes (GLDD) VP & CAO Ryan Bayer Receives Award, Sells 37,380 Shares

What Happened
Ryan Bayer, Vice President & Chief Accounting Officer of Great Lakes Dredge & Dock (GLDD), had a performance-based award of 5,607 shares vest and recorded a disposition of 37,380 shares as part of the April 1, 2026 merger. Under the merger agreement, each GLDD common share was converted into the right to receive $17.00 in cash. Based on that price, the vested award (5,607 shares) and the disposed shares (37,380 shares) correspond to cash amounts of approximately $95,319 and $635,460, respectively, for a combined total of about $730,779. The Form 4 reports the transactions as an award/acquisition (A) and a disposition in change of control (U); the filing lists per-share price as N/A, but the Merger Agreement sets the $17 cash consideration.

    • F3: The filing references 27,822 RSUs in total—20,899 were canceled and converted into cash at the Effective Time; 6,923 RSUs were replaced by a cash‑based award that remains subject to time‑based vesting conditions.

Context
This activity is a change-of-control conversion tied to the Saltchuk/Saltchuk Resources merger, not an open-market sale or a purchase signaling a personal investment decision. For derivative awards, the filing shows vested RSUs converting to cash and certain RSUs being replaced by cash‑based awards that continue to vest over time. Such merger-related dispositions are routine consequences of deal terms rather than standalone trading decisions.
