A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than September 21, 2026 . A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation. WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually handle securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered billions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers. DETAILS OF THE CASE: According to the lawsuit, throughout the Class Period, defendants made false and/or misleading statements and/or failed to disclose that: (1) 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; (2) 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 (3) 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 the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
