Rosen Law Firm is reminding investors who purchased Primoris Services Corporation common stock between August 5, 2025, and June 22, 2026, inclusive, that September 21, 2026, is the deadline to seek appointment as lead plaintiff in a securities class action. The lawsuit alleges that Primoris had deficient cost-estimation, cost-to-complete forecasting and project-oversight processes for significant fixed-price renewable energy projects, leading it to underestimate costs and risks amid overruns, execution problems and delays. A lawsuit has been filed, but no class has been certified. Eligible investors may seek compensation through a contingency-fee arrangement without paying out-of-pocket fees or costs, and their ability to participate in any potential recovery does not depend on serving as lead plaintiff.
