Rosen Law Firm has reminded investors who sold ChampionX Corporation common stock between February 29, 2024, and April 1, 2024, of the July 14, 2026, deadline to serve as lead plaintiff in a securities class action. The lawsuit alleges that ChampionX failed to disclose material information regarding acquisition offers, which artificially deflated the stock price during the Class Period. Investors who sold shares during this period may be entitled to compensation without out-of-pocket fees through a contingency fee arrangement.

According to the lawsuit, ChampionX received an unsolicited non-public offer from Schlumberger Limited on February 29, 2024, to purchase all outstanding shares for $36.70 per share. On March 7, 2024, Schlumberger raised its offer to $37.80 per share. During this time, ChampionX allegedly repurchased its common stock at market prices significantly below Schlumberger's offers, without disclosing the acquisition proposals to the public. The average stock price of ChampionX during the Class Period was $33.32 per share.

On April 2, 2024, ChampionX disclosed the merger with Schlumberger during pre-market hours. The merger closed on July 16, 2025, with Schlumberger acquiring ChampionX for $40.58 per share. The lawsuit claims ChampionX had an obligation to disclose the formal acquisition offer or abstain from repurchasing shares from unsuspecting investors.

Investors wishing to join the class action or serve as lead plaintiff must move the Court no later than July 14, 2026. The Rosen Law Firm emphasizes the importance of selecting qualified counsel with experience in securities class actions. No class has been certified yet, and investors may choose their own counsel or remain absent class members. The ability to share in any potential recovery is not dependent on serving as lead plaintiff.
