In the press release, Primoris disclosed increased costs on certain renewable energy projects, more challenging-than-anticipated soil conditions, and margin compression within its Energy segment, acknowledging that these issues adversely affected fourth-quarter profitability despite higher revenue. On this news, Primoris’s stock price fell $13.72 per share, or 8.28%, to close at $151.92 per share on February 24, 2026. Then, on May 5, 2026, Primoris issued a press release reporting its financial results for the first quarter of 2026. In the press release, Primoris disclosed additional adverse developments affecting its renewable energy business, including revenue and margin pressure, delayed project starts, and weaker-than-expected first-quarter 2026 results.
