HOUSTON, December 6, 2022—SLB (NYSE: SLB) today announced the early results of the previously announced offer by Schlumberger Holdings Corporation, an indirect wholly-owned subsidiary of SLB (“SHC”), to purchase for cash up to an aggregate purchase price amount, including premium but excluding any Accrued Interest (as defined below), of $500,000,000 (such amount, as it may be amended, the “Maximum Purchase Price”) of the notes listed in the table below (the “Notes”). The offer to purchase the Notes is referred to herein as the “Offer.” Additionally, SLB announced the increase of the Maximum Purchase Price from $500,000,000 to up to $800,000,000, and no Notes with Acceptance Priority Levels 3 and 4 will be accepted for purchase. All other terms of the previously announced Offer remain unchanged.

The Offer is made upon the terms and subject to the conditions set forth in the offer to purchase, dated November 21, 2022 (as may be amended or supplemented from time to time, the “Offer to Purchase”). Capitalized terms used but not defined in this press release have the meanings given to them in the Offer to Purchase.

1. SHC will accept Notes in accordance with their Acceptance Priority Level specified in the table above (each, an “Acceptance Priority Level,” with 1 being the highest Acceptance Priority Level and 4 being the lowest Acceptance Priority Level), subject to the terms and conditions described elsewhere in the Offer to Purchase, including the Maximum Purchase Price and proration. No Notes with Acceptance Priority Levels 3 and 4 will be accepted for purchase.

All documentation relating to the Offer, including the Offer to Purchase, together with any updates, are available from the Tender and Information Agent (as defined below) and are also available at the following website: http://www.dfking.com/slb.

SLB expects to announce the pricing of the Offer, including any proration with respect to the Notes accepted for purchase, later today, December 6, 2022.

Subject to satisfaction or waiver of the General Conditions by such date, all Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time and accepted for purchase will be purchased by the Company on the “Early Settlement Date,” which is expected to occur on December 8, 2022. All Holders of Notes that are purchased will receive, in addition to the applicable Total Consideration, a cash amount equal to the accrued and unpaid interest on the Notes, from, and including, the immediately preceding interest payment date up to, but excluding, the Early Settlement Date, rounded to the nearest cent per $1,000 principal amount of Notes.

The Offer is scheduled to expire at 11:59 p.m., New York City time, on December 19, 2022 (unless the Offer is extended or terminated) (such date and time, the “Expiration Time”). Withdrawal rights expired at 5:00 p.m., New York City time, on December 5, 2022. Notes that have been tendered may no longer be withdrawn. Since the amount of Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time exceeded the Maximum Principal Amount, no additional Notes will be accepted for purchase after the Early Tender Time.

Subject to applicable law and limitations described in the Offer to Purchase, SHC expressly reserves the right, in its sole discretion, to amend, extend or, upon failure of any condition described in the Offer to Purchase to be satisfied or waived, to terminate the Offer at any time at or prior to the Expiration Time.
