- Class Action Notice: Rosen Law Firm reminds shareholders who sold ChampionX stock between February 29 and April 1, 2024, to apply as lead plaintiffs by July 14, 2026, to potentially receive compensation without any out-of-pocket costs.
- Lawsuit Background: The lawsuit alleges that ChampionX failed to disclose material information during acquisition offers, which artificially deflated its stock price; Schlumberger initially offered $36.70 per share on February 29, 2024, later increasing it to $37.80, while ChampionX repurchased shares at lower market prices.
- Stock Price Impact: During the class period, ChampionX's average stock price was $33.32 per share, ultimately being acquired by Schlumberger for $40.58 per share on July 16, 2025, indicating potential investor losses due to undisclosed information.
- Law Firm's Strength: Rosen Law Firm specializes in securities class actions and has achieved the largest securities class action settlement against a Chinese company, recovering over $438 million for investors in 2019, showcasing its success and resource advantages in handling such cases.
