A securities class action lawsuit has been filed against DNOW Inc. over alleged federal securities law violations tied to its acquisition of MRC Global Inc. and disclosures about problems integrating MRC Global’s new enterprise resource planning (ERP) system, business software for company operations. The proposed investor class covers shareholders who held DNOW common stock on the August 5, 2025 record date and were entitled to vote at the September 9, 2025 special meeting on the merger. Hagens Berman said the lead plaintiff deadline is October 2, 2026. The complaint alleges that DNOW’s proxy materials understated or omitted material ERP integration risks. On November 5, 2025, the day before the merger closed, DNOW management reportedly described MRC Global’s ERP system as state-of-the-art and past software glitches as an isolated, one-time event. On February 20, 2026, DNOW disclosed persistent ERP challenges, declining MRC revenues, operational slowdowns, unexpected capital expenditures and delayed 2026 financial guidance. DNOW shares fell 19% in one trading session after the disclosures, according to the announcement. Hagens Berman partner Reed Kathrein said the firm is examining whether the proxy materials downplayed the failures to facilitate the transaction.
