ChampionX Corporation Shareholder Class Action Lawsuit
June 2, 2026 — The law firm of Federman & Sherwood, a national plaintiffs’ litigation firm representing shareholders and investors in complex securities matters, announces that it has commenced an investigation into potential securities law violations by ChampionX Corporation (“ChampionX” or the “Company”) (NASDAQ: CHX) on behalf of investors who sold ChampionX common stock between February 29, 2024 and April 1, 2024.
Details of the Lawsuit Investigation:
Federman & Sherwood’s investigation focuses on whether ChampionX and certain of its officers and directors failed to disclose material information to investors regarding acquisition offers received by the Company and whether the Company engaged in stock repurchases while in possession of material non-public information.
The investigation concerns allegations that ChampionX received an unsolicited acquisition proposal from Schlumberger Limited on February 29, 2024, offering to acquire the Company at a premium to its then-current market price. It is further alleged that Schlumberger subsequently increased its offer on March 7, 2024. During this period, ChampionX allegedly continued repurchasing its own shares at market prices without disclosing the existence of the acquisition proposals to investors.
Federman & Sherwood is investigating whether ChampionX had an obligation to disclose the acquisition proposals or refrain from repurchasing shares while in possession of material non-public information. The investigation will also examine whether investors were harmed by the Company’s alleged failure to disclose information that may have affected the market price of ChampionX stock.
Background:
ChampionX Corporation was a provider of chemistry solutions, artificial lift systems, and engineered equipment for the oil and gas industry. On April 2, 2024, ChampionX publicly announced that it had entered into a merger agreement with Schlumberger. The transaction subsequently closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share. Recent shareholder litigation has raised questions regarding whether material acquisition-related information was withheld from investors prior to the public announcement of the transaction.
What This Means for Investors:
Investors who sold ChampionX Corporation common stock during the relevant period and believe they may have been affected by the conduct described above may contact Federman & Sherwood for a free and confidential consultation. The firm is evaluating potential legal claims and all available remedies on behalf of affected shareholders.
