The lawsuit contends that Primoris failed to maintain reliable cost estimation and project oversight for its fixed-price renewable energy portfolio. According to the complaint, these systemic deficiencies led the company to consistently underestimate risks and expenses for projects plagued by execution delays and material cost overruns. Consequently, the firm's financial guidance and public disclosures during the period lacked a reasonable basis, causing significant losses for shareholders when the underlying issues surfaced.

Investors seeking to serve as lead plaintiff in the action must file their motions with the court by September 21, 2026. While the litigation proceeds, no class has been formally certified, meaning individuals are not yet represented by counsel unless they specifically retain one. Participation in any future settlement does not require an investor to serve as a lead plaintiff, and those affected may choose to remain absent class members or seek independent legal representation.
