Forward-looking statements involve risks, uncertainties and assumptions, and actual results may differ materially from any future results expressed or implied by such forward-looking statements. When used in this communication, or in the documents incorporated by reference, the words “guidance,” “anticipate,” “aim,” “believe,” “continue,” “could,” “estimate,” “expect,” “future,” “goal,” “intend,” “likely,” “likelihood,” “may,” “might,” “on track,” “outlook,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would,” “achieve,” “shall,” “seek,” “strategy,” “target,” “will” and similar expressions are intended to be among the statements that identify forward looking statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot assure you that such expectations will prove to be correct. These forward-looking statements speak only as of the date of this communication and we undertake no obligation to revise or update any forward-looking statement for any reason, except as required by law. Risks, uncertainties and assumptions that could affect our business, operating results, and financial condition include, but are not limited to, market conditions and changes in customer demand, the level of activity in the oil and gas industry and the offshore contract drilling industry, current and future prices of oil and gas, customer actions and new or substitute customer contracts, realization of our current backlog of contract drilling revenue, operating hazards, natural disasters, seasonal weather events and related damages or liabilities, acts of war, geopolitical conflict, risks relating to operations in international locations, upgrades, refurbishment, operation, and maintenance of our rigs and related operational interruptions and delays, sales of drilling units, supplier capacity constraints or shortages, nonperformance by third-parties, suppliers and subcontractors, regulatory changes, the impact of governmental laws and regulations on our costs and the offshore drilling industry, potential impacts, liabilities and costs from pending or potential investigations, claims and tax or other disputes, and other factors, including those detailed in Noble’s most recent Annual Report on Form 10-K, Quarterly Reports Form 10-Q and other filings with the U.S. Securities and Exchange Commission. We cannot control such risk factors and other uncertainties, and in many cases, we cannot predict the risks and uncertainties that could cause our actual results to differ materially from those indicated by the forward-looking statements. You should consider these risks and uncertainties when you are evaluating us. With respect to our capital allocation policy, distributions to shareholders in the form of either dividends or share buybacks are subject to the Board of Directors’ assessment of factors such as business development, growth strategy, current leverage and financing needs. There can be no assurance that a dividend or buyback program will be declared or continued. Non-GAAP Measures This presentation includes certain financial measures that we use to describe the Company's performance that are not in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). The non-GAAP information presented herein provides investors with additional useful information but should not be considered in isolation or as substitutes for the related GAAP measures. Moreover, other companies may define non-GAAP measures differently, which limits the usefulness of these measures for comparisons with such other companies. The Company defines "Adjusted EBITDA" as net income adjusted for interest expense, net of amounts capitalized; interest income and other, net; income tax benefit (provision); and depreciation and amortization expense, as well as, if applicable, gain (loss) on extinguishment of debt, net; losses on economic impairments; restructuring and similar charges; costs related to mergers and integrations; and certain other infrequent operational events. We believe that the Adjusted EBITDA measure provides greater transparency of our core operating performance. The Company defines net debt as indebtedness minus cash and cash equivalents; free cash flow as net cash provided by (used in) operating activities less capital expenditures net of proceeds from insurance claims; adjusted EBITDA margin as adjusted EBITDA divided by total revenues; and net leverage as net debt divided by annualized adjusted EBITDA from the most recently reported quarter. Noble believes these metrics and performance measures are widely used by the investment community and are useful in comparing investments among upstream oil and gas companies in making investment decisions or recommendations. These measures may have differing calculations among companies and investment professionals and a non-GAAP measure should not be considered in isolation or as a substitute for the related GAAP measure or any other measure of a company’s financial or operating performance presented in accordance with GAAP. Please see the Appendix to this communication for more information regarding the non-GAAP measures in this communication. Additionally, due to the forward-looking nature of Adjusted EBITDA and capital expenditures (net of reimbursements), management cannot reliably predict certain of the necessary components of the most directly comparable forward-looking GAAP measure. Accordingly, the company is unable to present a quantitative reconciliation of such forward-looking non-GAAP financial measure to the most directly comparable forward-looking GAAP financial measure without unreasonable effort. Contract Backlog The duration and timing (including both starting and ending dates) of the customer contracts are estimates only, and customer contracts are subject to cancellation, suspension, delays for a variety of reasons, and for certain customers, reallocation of term among contracted rigs, including some beyond Noble’s control. The contract backlog represents the maximum contract drilling revenues that can be earned when only considering the contractual operating dayrate in effect during the firm contract period. The actual average dayrate will depend upon a number of factors (e.g., rig downtime, suspension of operations, etc.) including some beyond Noble’s control. The dayrates do not include revenue for mobilizations, demobilizations, upgrades, contract preparation, shipyards or recharges, unless specifically otherwise stated. Dayrates may include revenue associated with performance including, for example, approximately 40% assumed performance revenue realized on a combined basis under certain long-term contracts with Shell (US) and TotalEnergies (Suriname). 2
