Primoris Services Corporation (PRIM) Investigation:

Hagens Berman's investigative focus is on the propriety of Primoris' statements about trends in—and operational performance of—Primoris' renewables business.

Primoris is fundamentally an energy and renewables company. In 2025, the Energy segment generated nearly two-thirds of the firm's total revenue. Within that segment, the renewable business has become the primary driver, alone accounting for roughly 40% of Primoris' entire annual revenue.

In February 2026, Primoris management attributed lower gross margins to "unexpectedly higher costs" at certain renewables projects, citing difficult soil and rock conditions that required additional labor and equipment. While management later downplayed the issue as being isolated to a single project—expressing confidence in their remedial measures—they simultaneously touted the company's ability to "accelerate project timelines" for 2026.

The market's confidence in Primoris's "remedial measures" was shattered following the release of the company's Q1 2026 financial results on May 5. The report revealed a staggering decline in the core Energy segment, with year-over-year revenues falling by $152.9 million (13.8%) and gross profits plunging by nearly 40%.

CEO Koti Vadlamudi admitted during the May 6 earnings call that Primoris's financial results were battered by cost pressures across multiple solar projects. Moving beyond the "rock and soil" reason used just months prior, Vadlamudi cited a litany of execution-related factors as the cause of the margin collapse:

• Project Redesigns: Costly changes to existing plans.
• Labor Issues: Inability to manage specific workforce demands.
• Sequencing Errors: Failures in project management and timing.
• Weather Disruptions: Further complicating already delayed timelines

The market swiftly reacted, sending the price of Primoris shares down 50% and wiping out about $5.5 billion of Primoris' market capitalization in a single day.

"We're focused on when Primoris' management learned of the renewable project execution issues revealed on the May earnings call," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation.
