San Francisco – September 11, 2026 -- DNOW Inc. (NYSE: DNOW) shares plunged 19% in a single session after the company disclosed that persistent ERP failures at newly acquired MRC Global Inc. had crushed revenues, triggering a securities class action lawsuit filed by Hagens Berman.
The suit centers on proxy materials tied to DNOW's merger with MRC Global, alleging management misrepresented the readiness of MRC's enterprise resource planning system ahead of a shareholder vote.

DNOW allegedly called ERP glitches an 'isolated, one-time event' before closing
On DNOW's Q3 2025 earnings call, held September 11, 2026 — the day before the merger closed — management reportedly told investors that MRC Global had implemented a "state-of-the-art" ERP system delivering improved inventory management, order processing, and supply chain optimization. Executives allegedly characterized MRC's prior software glitches as an isolated, one-time event, playing down integration risk to secure shareholder approval.

On September 11, 2026, DNOW's fourth-quarter and full-year 2025 results told a different story: MRC revenues had sharply declined due to what the company termed "persistent ERP challenges." Management acknowledged the software implementation was in fact an obstacle, conceding that flawed design architecture caused operational slowdowns, disrupted customer service, and demanded unplanned capital expenditure to fix.
