ChampionX Lawsuit: Investors Face July 14 Deadline to Join Securities Class Action

ChampionX Lawsuit investors who sold ChampionX Corporation shares during a specific period in 2024 have until July 14, 2026, to seek appointment as lead plaintiff in a securities class action, according to a reminder issued by Rosen Law Firm.

The law firm said the lawsuit covers investors who sold ChampionX Corporation (NASDAQ: CHX) common stock between February 29, 2024, and April 1, 2024. Eligible investors may be able to pursue compensation without paying upfront legal fees through a contingency fee arrangement.

The case alleges that ChampionX failed to disclose material information related to acquisition offers it received from Schlumberger Limited during the class period. According to the complaint, Schlumberger first made a non-public offer to acquire ChampionX for $36.70 per share on February 29, 2024, before increasing the offer to $37.80 per share on March 7, 2024.

The lawsuit claims ChampionX continued repurchasing its own shares at market prices averaging $33.32 per share while the acquisition proposals remained undisclosed. Plaintiffs argue that the company should have either informed investors about the takeover offers or paused its share repurchase program.

ChampionX publicly announced its merger agreement with Schlumberger on April 2, 2024. The transaction later closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share.

Investors who wish to serve as lead plaintiff must file their request with the court by July 14, 2026. The lead plaintiff represents the interests of other class members throughout the litigation.

Rosen Law Firm noted that no class has yet been certified. Investors may retain legal counsel of their choice or remain absent class members while preserving their ability to participate in any future recovery if the case succeeds.
