Shares of Primoris Services Corporation (NASDAQ: PRIM) are surging 20.31% in pre-market trading on Tuesday, building on the momentum from a 17.10% after-hours gain on Monday. The significant uptick comes in the wake of the company's exceptional second-quarter 2025 financial results and raised full-year guidance, which far exceeded analyst expectations.

Primoris, a leading provider of infrastructure construction and maintenance services, reported adjusted earnings per share (EPS) of $1.68 for Q2, handily beating the analyst consensus estimate of $1.08 by 55.6%. The company's revenue surged to $1.89 billion, surpassing the expected $1.69 billion by 11.8% and marking a 20.84% increase from the same period last year. Adjusted EBITDA came in at $154.8 million, well above the estimated $112.1 million, while adjusted net income reached $92.2 million, significantly higher than the projected $59 million.

Adding fuel to investor enthusiasm, Primoris raised its full-year 2025 guidance. The company now forecasts adjusted EPS in the range of $4.90 to $5.10, up from its previous guidance of $4.20 to $4.40. This upward revision reflects management's confidence in the company's future performance, driven by strong growth in its Energy and Utilities segments. The Energy segment, in particular, saw a 27% revenue increase due to growth in renewable energy activity. The impressive quarterly performance and upbeat outlook suggest that Primoris is well-positioned to capitalize on the growing demand for infrastructure services in the coming months, driving substantial investor interest and the pre-market stock price surge.
