Business Description

General Information Seadrill Limited is incorporated in Bermuda. We are an offshore drilling contractor providing worldwide offshore drilling services to the oil and gas industry. Our primary business is the ownership and operation of drilling units for operations in shallow to ultra-deepwater in both benign and harsh environments. We contract our drilling units to drill wells for our customers on a dayrate basis. Our customers include oil super-majors, state-owned national oil companies and independent oil and gas companies. In addition, we provide management services to certain affiliated entities. As of December 31, 2025, we owned a total of 15 drilling units, of which 10 were operating, one was undergoing capital upgrade projects for a contract commencing in the second quarter of 2026, one was undergoing repairs and maintenance projects and three were cold stacked. The 10 operating units include nine benign floaters (comprising six 7th generation drillships, two 6th generation drillships and one benign environment semi-submersible) and one harsh environment jackup. In addition to our owned assets, as of December 31, 2025, we managed two drilling units owned by Sonangol EP ("Sonangol").

Basis of presentation The Consolidated Financial Statements comply with US GAAP and are presented in U.S. dollars ("US dollar", "$" or "US$") rounded to the nearest million, unless stated otherwise. They include the financial statements of Seadrill Limited and its consolidated subsidiaries. The financial information in this report has been prepared on the basis we will continue as a going concern, which presumes we will be able to realize our assets and discharge liabilities in the normal course of business as they come due. Certain reclassifications have been made to previously reported amounts to conform to the current period presentation. These reclassifications did not have a material effect on our Consolidated Financial Statements. Use of estimates The preparation of the Consolidated Financial Statements in accordance US GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, and related disclosures about contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base these estimates and assumptions on historical experience and on various other information and assumptions that we believe to be reasonable. Critical accounting estimates are important to the portrayal of both our financial position and results of operations and require us to make subjective or complex assumptions or estimates about matters that are uncertain. Actual results may differ from these estimates. Basis of consolidation We consolidate companies where we have a controlling financial interest, and entities where we hold a variable interest and are the primary beneficiary. A variable interest entity ("VIE") is a legal entity where equity at risk is not enough to finance its activities, or equity interest holders lack power to direct activities or receive expected returns. We are the primary beneficiary of a VIE when we have the power to direct activities that impact economic performance and the right to receive benefits or absorb losses. We exclude subsidiaries, even if fully owned, if we are not the primary beneficiary under the variable interest model. All intercompany balances and transactions have been eliminated.
