PRIM IMPORTANT DEADLINE: ROSEN, RECOGNIZED INVESTOR COUNSEL, Encourages Primoris Services Corporation Investors with Losses in Excess of $100K to Secure Counsel Before Important Deadline in Securities Class Action - PRIM

Rosen Law Firm, a global investor rights law firm, reminds purchasers of common stock of Primoris Services Corporation (NYSE: PRIM) between August 5, 2025 and June 22, 2026, inclusive (the "Class Period"), of the important September 21, 2026 lead plaintiff deadline .

If purchased Primoris common stock during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than September 21, 2026 . A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

According to the lawsuit, throughout the Class Period, defendants made false and/or misleading statements and/or failed to disclose that: (1) Primoris' cost estimation, cost-to-complete forecasting, and project oversight processes were deficient and failed to provide reliable estimates of the costs and expected profitability of significant fixed-price renewable energy projects; (2) as a result, Primoris systematically underestimated the costs and risks of significant fixed-price renewable energy projects that were experiencing material cost overruns, execution problems, and schedule delays; and (3) accordingly, defendants' statements regarding Primoris' estimating processes, project execution, ability to manage project risk, financial performance, and financial guidance lacked a reasonable basis and omitted material adverse facts. When the true details entered the market, the lawsuit claims that investors suffered damages.
