Sterling Infrastructure (STRL) GC Mark D. Wolf Receives Award, Sells Shares

What Happened

Mark D. Wolf, General Counsel and Corporate Secretary of Sterling Infrastructure (STRL), reported the release of 2,996 performance-share units (PSUs) on 2026-02-25. Those PSUs were awarded at $0 cost but had market value.
To satisfy tax withholding tied to the PSU release, 1,193 shares were retained/disposed by the company at $455.25 per share for a total of $543,113. Net to Wolf were 1,803 shares (2,996 awarded minus 1,193 withheld). Of those, 1,505 shares remain subject to restrictions/forfeiture under certain conditions.

Key Details

Transaction date: 2026-02-25; Form 4 filed 2026-02-27 (timely).
Award: 2,996 shares (PSUs granted in 2023 that satisfied performance conditions).
Withholding/disposition: 1,193 shares at $455.25 each, totaling $543,113, used to satisfy tax withholding (company-retained).
Net shares delivered to insider: 1,803; of those, 1,505 remain restricted per the filing.
Filing appears to be a routine PSU settlement with tax withholding — not an open-market sale for investment liquidity.

Context

This was a PSU settlement (award release) rather than a market-motivated sale—the disposed shares were used to meet tax obligations (common practice when restricted/earned shares vest).
For retail investors, awards and tax-withholding sales generally do not signal the same trading intent as an open-market sale by an insider.
