Former Attorney General of Louisiana Charles C. Foti, Jr., Esq. and the law firm of Kahn Swick & Foti, LLC (“KSF”) are investigating the proposed sale of ChampionX Corporation (NasdaqGS: CHX) to Schlumberger Limited (NYSE: SLB). Under the terms of the proposed transaction, shareholders of ChampionX will receive 0.735 shares of SLB for each share of ChampionX that they own. KSF is seeking to determine whether this consideration and the process that led to it are adequate, or whether the consideration undervalues the Company.

Kahn (lewis.kahn@ksfcounsel.com) toll free at any time at 855-768-1857, or visit https://www.ksfcounsel.com/cases/nasdaqgs-chx/ to learn more.
