Glancy Prongay Wolke & Rotter LLP, a leading national shareholder rights law firm, today announced that it is investigating potential claims against the board of directors of acquired Primoris Services Corporation ("Primoris" or the "Company") (NYSE: PRIM) whether the board breached its fiduciary duties to shareholders.

On June 22, 2026, Primoris revealed a series of business updates including the departure of its Chief Operating Officer and a further slash to its financial outlook for the full year of 2026, in part due to “cost overruns and delays” related to six of the Company’s projects. The Company also said it anticipates lower revenue and gross profit for full year 2026, primarily driven by lower expected revenue and gross profit in the renewables business, where it now sees full-year revenue at $2.1 billion to $3 billion.
