Rosen Law Firm reminded purchasers of Primoris Services Corporation common stock between August 5, 2025, and June 22, 2026, of a September 21, 2026, deadline to seek appointment as lead plaintiff in a filed securities class action. Primoris trades on the New York Stock Exchange under the ticker PRIM. The lawsuit alleges that Primoris had deficient cost-estimation, cost-to-complete forecasting and project-oversight processes, causing it to underestimate costs and risks on significant fixed-price renewable energy projects experiencing overruns, execution problems and delays. The complaint claims the company’s statements about project execution, risk management, financial performance and guidance lacked a reasonable basis or omitted material adverse facts. No class has been certified, and investors may retain counsel, seek lead-plaintiff status or remain absent class members.
