Investors Face Losses as Primoris Services Faces Class Action Lawsuit

The lawsuit, Boston Retirement System v. Primoris Services Corporation, alleges that the infrastructure firm misled shareholders regarding its internal cost estimation and project oversight. Plaintiffs claim Primoris systematically underestimated risks and costs associated with its fixed-price renewable energy projects, resulting in repeated financial guidance downgrades and significant stock price volatility throughout the class period.

Legal filings detail a series of disclosures that decimated shareholder value. Following reports of margin compression and cost overruns, the company’s stock suffered sharp declines, including an 8% drop in February 2026 and a 50% plunge in May 2026 after the company slashed its earnings guidance. The situation intensified in June 2026, when the firm announced the departure of its President of Renewables and, subsequently, its Chief Operating Officer, Jeremy Kinch. A final June 22 update revealed that internal reviews confirmed substantial challenges across six major energy projects, triggering a further 22% stock price collapse.
