Kornblau Scott Lee 4/A

What Happened
Scott Kornblau, SVP & Chief Financial Officer of Great Lakes Dredge & Dock Corp (GLDD), received an award of 25,058 restricted stock units (RSUs) reported on May 8, 2025. The Form 4/A shows the grant (transaction code A); no per-share price or total dollar value is reported because these are time-based RSU awards that convert to shares upon vesting. This is a grant (compensation/incentive), not an open-market purchase or sale.

Key Details

• Transaction date: May 8, 2025 (reported originally on Form 4 filed May 12, 2025; amended Form 4/A filed March 25, 2026).
• Transaction type/code: Award/Grant (A) — 25,058 RSUs. Price: N/A (typical for RSU grants).
• Vesting: Corrected by amendment — vesting begins on May 8, 2026 (see footnote).
• Shares owned after transaction: Not disclosed in this filing.
• Footnote: The amendment corrects an administrative error in the original Form 4; the vesting start date was incorrectly reported as March 15, 2026 and now is May 8, 2026.
• Timeliness: Original Form 4 was filed May 12, 2025 for the May 8 transaction; this Form 4/A is an administrative correction.

Context: RSU grants are standard executive compensation and do not represent an immediate market buy or sell. They typically vest over time (here beginning May 8, 2026) and become shares upon vesting; they signal executive retention incentives rather than a direct view on near-term stock price.
