The complaint alleges that Primoris failed to maintain adequate cost-estimation and oversight processes, leading to systematic underreporting of expenses and delays across its fixed-price renewable energy portfolio. According to the filing, these internal deficiencies rendered the company’s public statements about its business prospects materially misleading throughout the specified period.

The company’s valuation suffered a series of sharp declines as negative operational updates emerged. Following an initial warning in February 2026, the stock dropped 8.3%. Subsequent disclosures—including a major guidance slash in May 2026 that saw shares plummet over 50%, the departure of key executives, and further warnings regarding cost overruns in June 2026—eroded significant shareholder value. By the end of the class period, the stock had experienced multiple double-digit percentage drops linked to these project-related revelations.
