A securities class action lawsuit has been filed against DNOW Inc. (NYSE: DNOW) over alleged failures to disclose material problems with MRC Global Inc.'s enterprise resource planning system during DNOW's acquisition of the company. Rosen Law Firm has reminded investors who held DNOW common stock on Aug. 5, 2025 and were entitled to vote at the Sept. 9, 2025 special meeting that Oct. 2, 2026 is the deadline to seek appointment as lead plaintiff. Earlier case information identified Hagens Berman in connection with the litigation and alleged that DNOW's proxy materials and later statements understated the integration risks. DNOW allegedly described MRC's ERP system as state-of-the-art and earlier glitches as isolated before disclosing on Feb. 20, 2026 that persistent problems had reduced MRC revenue, disrupted operations and customer service, required unexpected capital expenditures and delayed 2026 guidance. DNOW shares fell 19% in one trading session after the disclosure. No class has been certified, and investors may seek lead plaintiff status, retain counsel or remain absent class members without taking action. The Rosen notice says eligible investors may participate under a contingency-fee arrangement without out-of-pocket fees or costs.
