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. **What now:** You may be eligible to participate in the class action against ChampionX Corporation.
