The allegations: Robbins LLP is Investigating Allegations that ChampionX Corporation (CHX) Repurchased Shares of its Stock in Violation of Securities Laws According to the complaint, during the class period, defendants repurchased 216,000 shares of ChampionX stock – worth millions of dollars – from unsuspecting investors without disclosing material nonpublic information about SLB’s offers to purchase ChampionX at a premium to then-current prices. If this information had been disclosed as required it would have indicated to investors that ChampionX’s stock was worth significantly more. Plaintiff alleges that when investors learned the truth that SLB was willing to buy all of the Company's outstanding stock for a significant premium above the trading price, ChampionX's stock price climbed sharply, harming investors who sold during the class period.
