San Diego, California--(Newsfile Corp. - July 29, 2026) - Robbins LLP reminds investors that a securities class action has been filed on behalf of all persons and entities that purchased or otherwise acquired Primoris Services Corporation (NYSE: PRIM) securities between August 5, 2025 and June 22, 2026 (the "Class Period").

The lawsuit alleges that Primoris made materially false or misleading statements regarding the Company's cost forecasting, project oversight, and expected profitability of certain renewable energy construction projects.

Investors who suffered losses during the Class Period may have legal rights and should be aware of the September 21, 2026 deadline to seek appointment as lead plaintiff.

Why Was Primoris Sued?

The complaint alleges that Primoris misled investors regarding its ability to accurately estimate costs and manage risks associated with major fixed-price renewable energy projects.

Specifically, the lawsuit alleges that during the Class Period the Company:

• maintained deficient cost estimation, cost-to-complete forecasting, and project oversight processes;
• systematically underestimated the costs and risks associated with several significant fixed-price renewable energy projects;
• failed to disclose material cost overruns, project execution issues, and schedule delays affecting those projects; and
• made positive statements regarding its estimating practices, project execution, risk management, financial performance, and financial guidance that allegedly lacked a reasonable basis because they omitted material adverse information.

The complaint alleges that investors purchased Primoris securities at artificially inflated prices because these risks were not adequately disclosed.

What Happened to PRIM Stock?

According to the complaint, the truth emerged through a series of disclosures between February 23, 2026 and June 22, 2026.

The final disclosure occurred on June 22, 2026, when Primoris announced that an internal review, supported by an independent third-party industry expert, had identified:

• significant cost overruns;
• project delays;
• execution challenges affecting six renewable energy projects;
• a substantial reduction to the Company's 2026 financial guidance;
• lower revenue expectations for its Renewables segment; and
• the resignation of Chief Operating Officer David Kinch.

Following these disclosures, Primoris' stock price fell from $108.34 to $84.95 per share, a decline of approximately 21.6%.

Who May Be Eligible?

The lawsuit seeks to represent investors who purchased or otherwise acquired Primoris Services Corporation (NYSE: PRIM) securities during the applicable Class Period.

If you purchased Primoris stock during this period and suffered investment losses, you may have rights under the federal securities laws.

What Is a Lead Plaintiff?

The lead plaintiff is the investor appointed by the court to represent the interests of the proposed class throughout the litigation.

Investors do not have to serve as lead plaintiff to potentially share in any recovery if the lawsuit is successful.
