In 2013, SLB completed the wind-down of its service operations in Iran. Prior to this, certain non-US subsidiaries provided oilfield services to the National Iranian Oil Company and certain of its affiliates (“NIOC”).

SLB’s residual transactions or dealings with the government of Iran in 2023 consisted of payments of taxes and other typical governmental charges. Certain non-US subsidiaries of SLB maintained depository accounts at the Dubai branch of Bank Saderat Iran (“Saderat”), and at Bank Tejarat (“Tejarat”) in Tehran and in Kish for the deposit by NIOC of amounts owed to non-US subsidiaries of SLB for services rendered in Iran prior to the wind-down and for the maintenance of such amounts previously received. One non-US subsidiary also maintained an account at Tejarat for payment of local expenses such as taxes. SLB anticipates that it will discontinue dealings with Saderat and Tejarat following the receipt of all amounts owed to SLB for prior services rendered in Iran.
