Item 5.02 | Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On July 9, 2025, the Board of Directors (the “Board”) of Sterling Construction Company, Inc. (the “Company”) increased the size of the Board and appointed B. Andrew Rose and David Schulz as directors effective July 10, 2025. Mr. Rose and Mr. Schulz will serve until the Company's 2026 annual meeting of shareholders or until his successor is elected and qualified. Further, the Board has appointed Mr. Rose as a member of each of the Compensation and Talent Development Committee, and the Corporate Governance and Nominating Committee of the Board, and Mr. Schulz as a member of each of the Compensation and Talent Development Committee, and the Audit Committee of the Board. The Board determined that each of Mr. Rose and Mr. Schulz has no material relationship with the Company and is “independent” in accordance with the applicable NASDAQ listing standards and SEC rules. In addition, the Board determined that each of Mr. Rose and Mr. Schulz satisfies the additional director qualifications for members of the Compensation and Talent Development Committee, and Audit Committee, as applicable, set forth in the applicable NASDAQ listing standards and SEC rules, and that Mr. Schulz qualifies as an “audit committee financial expert” as such term is defined by the rules of the SEC. The appointment of Mr. Rose and Mr. Schulz was not pursuant to any arrangement or understanding between Mr. Rose and Mr. Schulz and any third party. As of the date of this report, neither Mr. Rose, or any of his immediate family members, nor Mr. Schulz, or any of his immediate family members, are a party, either directly or indirectly, to any transaction that would be required to be reported pursuant to Item 404(a) of Regulation S-K. The Company’s board is now comprised of eight directors, including seven independent directors. Mr. Rose and Mr. Schulz will be compensated consistent with the standard compensation program for non-employee directors, which includes a combination of cash and equity-based incentive compensation, which is described in the Company’s definitive proxy statement filed with the U.S. Securities and Exchange Commission on March 25, 2025, under the heading “Director Compensation.” In connection with their appointments to the Board, each of Mr. Rose and Mr. Schulz will receive a pro-rated award of shares of restricted stock valued at $111,698, with the number of shares determined based on the Company’s closing price on July 10, 2025. A copy of the Company’s press release issued on July 10, 2025, regarding Mr. Rose and Mr. Schulz appointments, is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
