A securities fraud class action lawsuit is pending against Primoris Services Corporation in the United States District Court for the Northern District of Texas on behalf of investors who purchased or acquired Primoris common stock during the August 5, 2025, to June 22, 2026, Class Period. The case is captioned Boston Retirement System v. Primoris Services Corp., No. 26-cv-02416; the existing case record identifies it as No. 3:26-cv-02416. The complaint alleges that Primoris and certain executives violated federal securities laws by failing to disclose deficiencies in cost estimation, cost-to-complete forecasting and oversight of fixed-price renewable energy projects. Primoris disclosed on June 22 that an internal review supported by an independent third-party industry expert had identified substantial challenges, cost overruns and delays affecting six renewable energy projects. The company reduced its 2026 Adjusted EPS guidance to $2.05-$2.60, lowered Adjusted EBITDA guidance to $275 million-$325 million, projected 2026 Renewables revenue of approximately $2.1 billion and announced its Chief Operating Officer's resignation. The KSF release says shares fell 22% and closed at $84.95 on June 23; the existing record says they fell 21.6% to $84.95 on June 22. Earlier disclosures included higher renewable-project costs and margin compression on February 23, a reduction in Adjusted EBITDA guidance from $560 million-$580 million to $480 million-$500 million on May 5, and the immediate departure of the President of Renewables on June 8. Investors have until September 21, 2026, to seek appointment as lead plaintiff. Rosen Law Firm is soliciting investors and says participation is available through a contingency-fee arrangement without out-of-pocket fees or costs. No class has been certified, and investors may seek lead-plaintiff appointment, retain counsel of their choice, remain absent class members or take no action. Kahn Swick & Foti and Kessler Topaz Meltzer & Check have also solicited investors regarding recovery options.
