Primoris Services Faces Investor Probe After 50% Stock Plunge

The sudden loss of $5.5 billion in market capitalization stems from a sharp departure from earlier executive optimism. In February 2026, management characterized margin pressures as isolated incidents tied to difficult soil conditions. However, the Q1 2026 financial report revealed that the problems were widespread, with Energy segment revenues dropping by $152.9 million and gross profits plummeting nearly 40% year-over-year.

During the May 6 earnings call, CEO Koti Vadlamudi acknowledged that the company’s renewables division—which accounts for roughly 40% of total annual revenue—is suffering from deep-seated operational issues. These include costly project redesigns, workforce mismanagement, sequencing errors, and weather-related delays. Hagens Berman partner Reed Kathrein stated the firm is now investigating whether Primoris provided accurate disclosures regarding the health of these projects before the May 5 market close. The investigation seeks to determine if investors were misled about the severity of the operational hazards facing the company’s primary revenue driver.
