Grabar Law Office is investigating claims on behalf of shareholders of Primoris Services Corporation (NYSE: PRIM). The investigation concerns whether certain officers and directors breached the fiduciary duties they owed to the company.

Primoris Services Corporation provides infrastructure services primarily in the United States and Canada. The company operates in two segments: Utilities and Energy. The Utilities segment offers installation and maintenance of new and existing natural gas and electric utility distribution and transmission systems, and communications systems. The Energy segment provides engineering, procurement, construction, and maintenance services for entities in the energy, renewable energy and energy storage, renewable fuels, and petroleum and petrochemical industries, as well as state departments of transportation. The company also provides replacement services.

WHY? As alleged in a recently filed securities fraud class action Complaint, Primoris Services Corporation (NYSE: PRIM), through certain of its officers, made materially false and misleading statements and/or failed to disclose 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, defendants’ statements regarding Primoris’ estimating processes, project execution, ability to manage project risk, financial performance, and financial guidance lacked a reasonable basis and omitted material adverse facts when made.

The Primoris class action lawsuit further alleges that on February 23, 2026, Primoris reported its fourth quarter and full year 2025 financial results, disclosing 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, the price of Primoris stock fell 8%, according to the complaint.

Then, on May 5, 2026, Primoris reported its financial results for the first quarter of 2026, in which the company 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. Primoris 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, the complaint alleges. On this news, the price of Primoris stock fell approximately 50%, according to the complaint.

Thereafter, on June 8, 2026, Primoris allegedly announced that Anthony Vorderbruggen, Primoris’ President of Renewables, was departing the Company, effective immediately. On this news, the price of Primoris stock fell approximately 15%, according to the complaint.

Finally, on June 22, 2026, Primoris issued a Business Update in which it announced that, following an internal review supported by an independent third-party industry expert, it had identified substantial challenges, cost overruns, and project delays affecting six renewable energy projects. Primoris reduced its full-year 2026 Adjusted EPS guidance to $2.05-$2.60, lowered its Adjusted EBITDA guidance to $275 million-$325 million, projected that 2026 Renewables revenue would decline to approximately $2.1 billion, and announced the resignation of its Chief Operating Officer, defendant Jeremy Kinch. The class action lawsuit alleges that on this news, the price of Primoris stock fell 22%.
