What Happened?

On May 5, 2026, Primoris reported its first quarter 2026 financial results and updated its full-year outlook. Among other things, the Company disclosed revenue of $1.6 billion, down 5.4% compared to the prior-year period, and net income of $17.4 million, compared to $44.2 million in the prior-year period. Primoris further disclosed that Energy segment operating income decreased by $49.1 million, or 62.2%, compared to the prior-year period, due to decreased revenue and increased costs on certain renewable energy projects. The Company stated that these higher costs were driven in part by project redesign efforts, changes in project sequencing, labor productivity challenges, and unfavorable weather conditions. Energy gross profit as a percentage of revenue declined to 7.6%, compared to 10.7% in the prior-year period. On this news, the price of Primoris shares declined by $101.69 per share, or approximately 50%, from $202.92 per share on May 5, 2026 to close at $101.23 on May 6, 2026.

Then on June 22, 2026, Primoris issued a Business Update revealing additional challenges and cost overruns in its Renewables business. The Company disclosed that the expected cost overruns were primarily related to six previously discussed projects, with several of those projects now expected to reach substantial completion during the third and fourth quarters of 2026. Primoris also disclosed that it anticipated lower revenue and gross profit for full-year 2026, primarily driven by lower expected revenue and gross profit in the Renewables business. The Company stated that it now expects full-year 2026 Renewables revenue of approximately $2.1 billion, compared to approximately $3.0 billion for full-year 2025. As a result, Primoris again reduced its full-year 2026 outlook. The Company now expects net income of $71 million to $101 million, EPS of $1.30 to $1.85, adjusted EPS of $2.05 to $2.60, and adjusted EBITDA of $275 million to $325 million. This compares to its prior May 2026 guidance of net income of $223 million to $234 million, EPS of $4.05 to $4.25, adjusted EPS of $4.80 to $5.00, and adjusted EBITDA of $480 million to $500 million. Primoris also announced the departure of Jeremy Kinch from the Chief Operating Officer role, effective immediately. On this news, the price of Primoris shares declined by $23.39 per share, or approximately 22%, from $108.34 per share on June 22, 2026 to close at $84.95 on June 23, 2026.

At this stage, no lawsuit has been filed. The investigation is ongoing to determine whether claims may be brought under federal securities laws.
