What Happened
Eleni Beyko, SVP — Offshore Energy at Great Lakes Dredge & Dock (GLDD), received 24,606 performance-based restricted shares that vested on March 16, 2026 (14,754 and 9,852 shares). To satisfy tax withholding on the vesting, 12,545 shares were surrendered (disposed) at an effective per-share amount of $16.93, totaling $212,387. These transactions reflect awards vesting and routine tax-withholding, not open-market sales or purchases.

Key Details

  • Transaction date: March 16, 2026; Form 4 filed March 18, 2026 (filed within the typical two-business-day window).
  • Award: 24,606 shares issued upon satisfaction of performance conditions (performance-based RSUs tied to grants on March 15, 2023 and March 15, 2024).
  • Withheld/disposed shares: 12,545 shares withheld to cover tax liabilities at $16.93 per share (total ~$212,387).
  • Net shares retained from this vesting event: 24,606 awarded − 12,545 withheld = net +12,061 shares issued to the insider.

  • Transaction codes: A = Award/Grant; F = Payment of exercise price or tax liability (here used for share-withholding to cover taxes).

Context
These were performance-based restricted stock unit (RSU) vestings and related tax-withholding (a common treatment where the company retains/surrenders some vested shares to cover taxes). This is compensation-related and does not represent an open-market sale or a discretionary insider purchase. For retail investors, such awards modestly increase an insider’s stake (net +12,061 shares here) but the withheld shares are routine and primarily for tax compliance.
