Primoris Services Corporation (NYSE: PRIM) investors who bought securities between August 5, 2025 and June 22, 2026 have until September 21, 2026 to ask the court to be appointed lead plaintiff in a securities class action flagged by Robbins LLP. The complaint alleges Primoris made materially false or misleading statements about cost forecasting, project oversight and the expected profitability of certain renewable energy construction projects, while understating costs and risks on major fixed-price renewable energy projects and failing to disclose cost overruns, execution issues and schedule delays. Robbins LLP says the alleged truth emerged through disclosures between February 23, 2026 and June 22, 2026, culminating in Primoris disclosing that an internal review supported by an independent third-party industry expert found significant cost overruns, project delays and execution challenges affecting six renewable energy projects, alongside a substantial cut to 2026 financial guidance, lower revenue expectations for the Renewables segment and the resignation of Chief Operating Officer Jeremy Kinch. Primoris shares fell from $108.34 to $84.95 per share, or about 21.6%, following those disclosures, the complaint says.
