ChampionX Corporation Class Action Lawsuit Draws Investor Attention After Berger Montague Announcement
ChampionX Corporation Class Action Lawsuit Draws Investor Attention After Berger Montague Announcement
Philadelphia, Pennsylvania — A new investor notice has placed ChampionX Corporation, formerly traded on NASDAQ under the ticker symbol CHX, at the center of a securities class action lawsuit involving allegations tied to share repurchases, undisclosed acquisition interest, and investor rights.
According to an announcement released by Berger Montague PC on May 26, 2026, the lawsuit has been filed on behalf of investors who sold ChampionX common stock between February 29, 2024 and April 1, 2024. This period is identified as the proposed class period.
Key Details of the ChampionX Investor Lawsuit
The complaint alleges that ChampionX purchased company shares at prices that were allegedly artificially depressed while material non-public information existed. The lawsuit claims that ChampionX had received a non-public acquisition offer from SLB before the merger was publicly disclosed.
The announcement states that ChampionX allegedly received an unsolicited offer from SLB on February 29, 2024 to acquire all outstanding shares at $36.70 per share. SLB later increased its offer to $37.80 per share on March 7, 2024.
During the same class period, ChampionX’s average stock price was reportedly $33.32 per share, which was below the alleged offer prices. The lawsuit argues that investors who sold shares during this period may have done so without knowing about the acquisition discussions.
Allegations Against ChampionX
The complaint alleges that ChampionX failed to disclose important information to the market. Specifically, the lawsuit claims that the company did not reveal that it had received an acquisition offer from SLB, that it allegedly had a duty to disclose the offer or avoid repurchasing shares, and that it continued buying back common stock while the offer remained unknown to public investors.
These allegations have not yet been proven in court. A class action lawsuit represents claims made by plaintiffs, and the defendants will have the opportunity to respond through the legal process.
Merger Disclosure and Final Acquisition
ChampionX publicly announced its merger agreement with SLB during pre-market hours on April 2, 2024. The merger later closed on July 16, 2025, with SLB acquiring ChampionX for $40.58 per share.
Before the acquisition, ChampionX was headquartered in The Woodlands, Texas and provided chemistry solutions, technologies, and services for the global oil and gas industry.
Investor Deadline
Berger Montague stated that investors who sold ChampionX common stock during the class period may seek appointment as lead plaintiff no later than July 14, 2026.
A lead plaintiff is typically an investor selected by the court to represent the interests of the proposed class. Investors are not required to serve as lead plaintiff to potentially share in any future recovery, if one occurs.

Why This Case Matters to Investors
This case may be important for former ChampionX investors because it focuses on whether sellers of CHX common stock had access to fair and complete market information before selling their shares. If the court allows the case to proceed, the litigation may examine company conduct, timing of share repurchases, merger discussions, disclosure duties, and investor losses.
The lawsuit also highlights broader concerns in securities markets, including corporate transparency, insider information, merger negotiations, and the responsibilities companies may have when buying back their own shares.
