Andrew Rose and David Schulz, effective July 10, 2025.

Additionally, Sterling Infrastructure reached a new 1-year high as of June 28, 2025, indicating strong market performance. This achievement has likely driven increased investor interest and confidence in the stock, contributing to its recent upward trajectory.

Furthermore, Vanguard Group Inc significantly increased its stake in Sterling Infrastructure by acquiring 753,630 shares on June 30, 2025. This move suggests institutional confidence in the company’s future prospects, which can further bolster investor trust and drive stock price appreciation.

Lastly, Sterling Infrastructure renegotiated its credit agreement, extending the maturity to June 2028 and increasing the facility size. This financial maneuver provides the company with greater stability and growth opportunities, which can positively influence investor perceptions and stock performance.
