EXPLANATORY NOTE

This Post-Effective Amendment No. 1 relates to the Registration Statement on Form S-8 (File No. 333-288443) (the “Registration Statement”) of Schlumberger Limited (Schlumberger N.V.), a Curaçao corporation (“SLB” or the “Registrant”), which was filed with the Securities and Exchange Commission on July 1, 2025. The Registration Statement registered up to 24,000,000 shares of the Registrant’s common stock, par value $ 0.01 per share (“SLB Common Stock”), to be offered pursuant to the SLB Discounted Stock Purchase Plan.

On July 16, 2025, Sodium Merger Sub, Inc., a Delaware corporation and an indirect wholly owned subsidiary of the Registrant (“Merger Sub”), completed its merger with ChampionX Corporation, a Delaware corporation (“ChampionX”), in an all-stock transaction at a fixed exchange ratio (the “Exchange Ratio”) of 0.735 shares of SLB Common Stock for each share of ChampionX common stock (the “Merger”) issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (other than any shares of ChampionX common stock held in the treasury of ChampionX or held by SLB, Sodium Holdco, Inc., a Delaware corporation (“Sodium US”), or any direct or indirect wholly owned subsidiary of SLB, in each case except for any such shares held on behalf of third parties), pursuant to the terms and conditions of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of April 2, 2024, by and among SLB, Sodium US, Merger Sub, and ChampionX.

At the Effective Time, and by virtue of the Merger: (a) each ChampionX option that was outstanding immediately prior to the Effective Time was converted into an option to acquire a number of shares of SLB Common Stock determined based on the Exchange Ratio; (b) each ChampionX restricted stock unit award that was outstanding immediately prior to the Effective Time was assumed and converted into a restricted stock unit award to acquire a number of shares of SLB Common Stock (“SLB RSU Award”) determined based on the Exchange Ratio; (c) each ChampionX performance share award that was outstanding immediately prior to the Effective Time was assumed and converted into a SLB RSU Award (covering a number of shares determined based on the Exchange Ratio, and based on the attainment of performance levels set forth in the Merger Agreement); and (d) each ChampionX restricted stock award that was outstanding immediately prior to the Effective Time was assumed and converted into an SLB restricted stock award (covering a number of shares determined based on the Exchange Ratio) (collectively, “Assumed Awards”).

This Post-Effective Amendment No. 1 is being filed by SLB to include in the Registration Statement shares of SLB Common Stock issuable upon the exercise or settlement of the Assumed Awards held by current directors, officers and employees of SLB who were directors, officers and employees of ChampionX immediately prior to the Effective Time. No additional securities are being registered hereby. As a result of this Post-Effective Amendment No. 1, the Registration Statement registers up to 20,000,000 shares of SLB Common Stock to be offered pursuant to the SLB Discounted Stock Purchase Plan, and up to 3,000,000 shares of SLB Common Stock issuable upon the exercise or settlement of the Assumed Awards as described herein.
