Primoris Faces Class Action Lawsuit Following $6 Billion Market Slide

The legal action, filed by Hagens Berman Sobol Shapiro LLP, targets a period between August 5, 2025, and June 22, 2026. Plaintiffs contend that while company leadership repeatedly touted disciplined bidding and reliable risk management, the reality was a systematic underestimation of costs across multiple high-stakes renewable projects. This disconnect between public assurance and internal oversight resulted in a market capitalization loss exceeding $6 billion in less than two months.

Confidence in Primoris began to erode in February 2026, when management first attempted to explain away margin compression as an isolated issue caused by challenging soil conditions. The narrative shifted drastically on May 6, 2026, when shares plummeted $101.69 following a dismal Q1 earnings report. CEO Koti Vadlamudi subsequently attributed the financial collapse to a failure of execution, citing labor shortages, sequencing errors, and costly project redesigns. A final blow arrived on June 23, 2026, when the stock dropped another 21% after the company announced a projected 30% revenue decline for its renewables segment. Investors with substantial losses have until September 21, 2026, to apply for the role of lead plaintiff.
