DEADLINE TOMORROW: Berger Montague Advises ChampionX Corporation (CHX) Investors to Contact the Firm Before July 14, 2026

National plaintiffs' law firm Berger Montague PC announces a class action lawsuit against ChampionX Corporation (NASDAQ: CHX) ("ChampionX" or the "Company") on behalf of investors who sold ChampionX common stock during the period from February 29, 2024 through April 1, 2024 (the "Class Period"). Investor Deadline: Investors who sold ChampionX common stock during the Class Period may, no later than July 14, 2026, seek to be appointed as a lead plaintiff representative of the class.

Prior to its acquisition by SLB in July 2025, ChampionX, headquartered in The Woodlands, TX, was a provider of chemistry solutions and technologies serving the global oil and gas sector. The Complaint alleges that throughout the Class Period, ChampionX purchased Company shares at artificially depressed prices due to material non-public information. Specifically, defendants allegedly failed to disclose that: (i) ChampionX had received an unsolicited, non-public acquisition offer from SLB; (ii) ChampionX had an obligation to either disclose the offer or abstain from repurchasing its shares; and (iii) while those offers were on the table and unknown to the investing public, ChampionX was repurchasing its common stock at market prices significantly below the prices offered by SLB.

On February 29, 2024, ChampionX received an unsolicited, non-public offer from SLB to acquire all outstanding shares at $36.70 per share. On March 7, 2024, SLB raised its offer to $37.80 per share. During the Class Period, ChampionX's average stock price was $33.32 per share - significantly below the undisclosed offer prices. On April 2, 2024, during pre-market hours, ChampionX disclosed the merger with SLB. The merger eventually closed on July 16, 2025, with SLB acquiring ChampionX for $40.58 per share.
