Sterling Infrastructure, Inc. reported an insider ownership change involving Nicholas M. Grindstaff, with the transaction dated July 10, 2026 and the Form 4 signed July 14, 2026. The filing indicates that shares of Sterling common stock were retained by the company at Grindstaff’s election to satisfy tax withholding obligations tied to the release of restrictions on a restricted stock unit award. The withholding amount was determined using the closing price of Sterling’s common stock on the release date, as permitted under the equity plan governing the award and under a procedure approved by the Compensation Committee of the board. This type of transaction generally reflects a tax-settlement mechanism following vesting or release of restricted equity, rather than an open-market sale for investment purposes. The document does not provide the number of shares withheld, the transaction code, the closing price used for the tax calculation, or Grindstaff’s total beneficial ownership after the transaction in the text provided. The filing does note that, among Grindstaff’s reported holdings, 4,735 shares remain subject to restrictions on sale or transfer and may be forfeited under certain circumstances. That detail indicates he continues to hold restricted Sterling equity following the reported tax-withholding event.
