The lawsuit, Boston Retirement System v. Primoris Services Corporation, alleges that the company misled shareholders regarding the costs and risks associated with its fixed-price renewable energy projects. According to the complaint, Primoris failed to maintain reliable oversight and cost-estimation processes, which resulted in systemic underestimations of expenditures and persistent project delays.

Shareholder losses were punctuated by a series of disclosures throughout 2026. Following reports of margin compression and increased costs in February, the stock price fell by 8.3%. Subsequent revelations—including slashed EBITDA guidance in May, the departure of the President of Renewables in June, and a further reduction in financial outlook later that month—triggered additional sell-offs. By June 22, 2026, the company’s share price had dropped to $84.95, a sharp decline from its levels during the class period.

Investors currently have until September 21, 2026, to file for lead plaintiff status. Legal firm Kessler Topaz Meltzer & Check, LLP is providing case evaluations for affected shareholders, noting that investors may also choose to remain absent class members. Participation in the litigation, or the decision to serve as a lead plaintiff, does not impact an individual investor's ability to share in a potential court-ordered recovery.
