A securities fraud class action has been filed against Primoris Services Corporation (NYSE: PRIM) on behalf of investors who purchased or acquired its common stock between Aug. 5, 2025, and June 22, 2026. The case, Boston Retirement System v. Primoris Services Corporation, No. 3:26-cv-02416, is pending in the U.S. District Court for the Northern District of Texas. The complaint alleges that Primoris made material misstatements or omissions about deficient cost-estimation, cost-to-complete forecasting and project-oversight processes on significant fixed-price renewable energy projects that faced overruns, execution problems and delays. After the company disclosed higher renewable project costs and Energy-segment margin compression with its Feb. 23, 2026 results, the stock fell $13.72, or 8.3%, to $151.92 on Feb. 24. On May 5, 2026, Primoris reported weaker first-quarter results and cut full-year adjusted EBITDA guidance from $560–$580 million to $480–$500 million, and the shares fell $101.69, or 50.11%, to $101.23 the next day; the company also lowered 2026 Adjusted EPS guidance from $5.80–$6.00 to $4.80–$5.00. Further declines followed the June 8 departure of its President of Renewables and a June 22 update citing cost overruns and delays on six projects, the COO’s departure, reduced 2026 Adjusted EPS guidance to $2.05–$2.60, Adjusted EBITDA guidance to $275–$325 million, and renewables revenue expected at $2.1 billion to $3 billion, with the stock falling $23.39, or 21.6%, to $84.95. Investors have until Sept. 21, 2026, to seek lead plaintiff status.
