A lead plaintiff is a representative party acting on other class members’ behalf in directing the litigation. Your ability to share in any recovery doesn’t require that you serve as lead plaintiff.

About The Lawsuit:

A lawsuit was filed on behalf of investors (the “Class”) who sold the common stock of ChampionX between February 29, 2024 and April 1, 2024, inclusive, alleging violations of the Securities Exchange Act of 1934 against the Company and certain of its senior officers.

The lawsuit alleges that defendants repurchased millions of dollars’ worth of ChampionX shares without disclosing material nonpublic information about Schlumberger Limited’s offers to purchase ChampionX at a premium to then-current prices, which, if disclosed as required, would have indicated to investors that ChampionX’s stock was worth significantly more.
