San Francisco – September 10, 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.
