What Is This Lawsuit About? The lawsuit alleges that Primoris made materially false and misleading statements regarding Primoris’ cost estimation, cost-to-complete forecasting, project execution, ability to manage project risk, financial performance, and financial guidance because the Company knew or recklessly disregarded that: (i) Primoris’ cost estimation, cost-to-complete forecasting, and project oversight processes were deficient and failed to provide reliable estimates of the costs and expected profitability of significant fixed-price renewable energy projects; (ii) as a result, Primoris systematically underestimated the costs and risks of significant fixed-price renewable energy projects that were experiencing material cost overruns, execution problems, and schedule delays; and (iii) accordingly, the Company’s statements regarding its estimating processes, project execution, ability to manage project risk, financial performance, and financial guidance lacked a reasonable basis and omitted material adverse facts.

On February 23, 2026, Primoris reported fourth quarter and full-year 2025 financial results, disclosing increased costs on certain renewable energy projects, more challenging-than-anticipated conditions, and margin compression within its Energy segment, acknowledging that these issues adversely affected profitability despite higher revenue. On this news, Primoris’ stock price fell $13.72 per share, or over 8%, to close at $151.92 per share on February 24, 2026.

Then, on May 5, 2026, the Company reported first quarter 2026 results, 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. The Company also reduced its full-year 2026 Adjusted EPS guidance from $5.80-$6.00 to $4.80-$5.00 and lowered its Adjusted EBITDA guidance. On this news, Primoris’ stock price fell by $101.69, or over 50%, to close at $101.23 per share on May 6, 2026.

On June 8, 2026, Primoris announced that Anthony Vorderbruggen, the Company’s President of Renewables, was departing the Company, effective immediately. On this news, Primoris’ stock price declined approximately 15%, closing at $103.90 per share on June 9, 2026.

Finally, on June 22, 2026, Primoris announced that an internal review, supported by an independent third-party industry expert, had identified significant cost overruns, project delays, and execution challenges affecting six renewable energy projects. The Company also reduced its 2026 Adjusted EPS guidance to $2.05-$2.60 and lowered its Adjusted EBITDA guidance. Additionally, Primoris announced the resignation of Jeremy Kinch as Chief Operating Officer. On this news, Primoris’ stock price fell by $23.39 per share, or over 21%, to close at $84.95 on June 23, 2026.

The Lead Plaintiff Appointment Process. The federal securities laws permit any investor who acquired eligible securities during the class period to seek appointment as lead plaintiff in a class action lawsuit. Learn more about the lead plaintiff process and eligibility requirements here. Courts typically appoint the investor(s) with the largest financial loss in the case and the ability to represent the class rather than investors with simply the largest investment portfolio. Courts regularly appoint individual investors, whether acting alone or as a group, as lead plaintiffs. The rights of any investor who bought shares during the class period are generally already protected. However, lead plaintiffs have the power to influence case strategy and have a say in settlement decisions, as well as decisions concerning allocation of settlement funds among class members.
