Primoris Services stock plunges over 45% after cutting 2026 earnings forecast, legal probe launched.

Primoris Services Corporation's stock dropped more than 40% on May 6, 2026, following a disappointing Q1 earnings report and a significant reduction in full-year adjusted EBITDA guidance from $560-$580 million to $480-$500 million. The company cited lower renewable energy activity, project delays, and rising costs as reasons for the cut, contradicting earlier optimistic statements about renewables margins. Block & Leviton LLP has initiated an investigation into potential securities law violations by Primoris and is encouraging affected investors to contact them for possible recovery of losses. Investors who purchased Primoris stock and experienced losses may be eligible for legal action, regardless of whether they have sold their shares.
