Business Description

Valaris Limited is a global offshore contract drilling company. Unless the context requires otherwise, the terms "Valaris," "Company," "we," "us" and "our" refer to Valaris Limited together with all its subsidiaries and predecessors. We are a leading provider of offshore contract drilling services to the international oil and gas industry with operations in almost every major offshore market across six continents. Our fleet of offshore drilling rigs is among the largest in the world and includes one of the highest specification ultra-deepwater fleets, as well as a leading premium jackup fleet. As of February 20, 2026, we own 46 rigs, including 13 drillships, two semisubmersible rigs, 31 jackup rigs and a 50% equity interest in ARO, our 50/50 unconsolidated joint venture with Saudi Aramco, which owns an additional nine rigs. Our customers include many of the leading international and government-owned oil and gas companies, in addition to many independent operators. We are among the most geographically diverse offshore drilling companies with global operations. The markets in which we operate include the Gulf of America, South America, the North Sea, the Mediterranean, the Middle East, Africa and Asia Pacific. We provide drilling services on a day rate contract basis. Under day rate contracts, we provide an integrated drilling service that includes the provision of a drilling rig and rig crews for which we receive a daily rate that may vary between the full rate and zero rate throughout the duration of the contractual term, depending on the operations of the rig. We also may receive lump-sum fees or similar compensation for the mobilization, demobilization and capital upgrades of our rigs. Our customers bear substantially all of the costs of constructing the well and supporting drilling operations as well as the economic risk relative to the success of the well. Pending Business Combination with Transocean On February 9, 2026, Valaris and Transocean Ltd. ("Transocean") entered into a business combination agreement (the “Business Combination Agreement”) under which Transocean will acquire all of the issued and outstanding common shares of Valaris in exchange for shares of Transocean at an exchange ratio of 15.235 Transocean shares for each Valaris share. The Business Combination will be effected by way of a court-approved scheme of arrangement between Valaris and the holders of the Valaris shares pursuant to section 99 of the Companies Act 1981 of Bermuda, as amended. The Transocean shares are expected to be issued in reliance on the exemption from the registration requirements of the U.S. Securities Act of 1933, as amended, provided by Section 3(a)(10) thereof and pursuant to exemptions from registration under any applicable state securities laws. Following the consummation of the Business Combination, Transocean’s existing shareholders and Valaris’ existing shareholders will own approximately 53% and 47%, respectively, of the combined company on a fully diluted basis assuming conversion to shares of Transocean’s exchangeable bonds due 2029. See " Par t II . Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations - Introduction - Pending Business Combination with Transocean" for further information . 6 Our Industry The offshore drilling industry is cyclical and primarily influenced by global energy demand, oil and gas supply dynamics and customer capital allocation decisions. Periods of oil oversupply generally place downward pressure on commodity prices, while periods of undersupply can result in higher and more volatile oil prices, influencing investment decisions across the upstream sector. While the oil market is currently in a period of oversupply, industry fundamentals are generally viewed as constructive over the medium to long term. Market participants generally expect the current oil supply imbalance to shift to a structurally tighter market over the next few years, driven by past underinvestment in upstream development and slowing production growth from non-OPEC sources. Industry studies, including those published by the International Energy Agency and the U.S. Energy Information Administration, indicate that substantial upstream investment is required to offset natural field declines and maintain existing production levels.…
