Noble Corporation plc Fourth Quarter 2024 Earnings Conference Call February 18, 2025

Disclaimer Forward-Looking Statements This communication includes “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act, as amended. All statements other than statements of historical facts included in this communication are forward looking statements. These statements, opinions, forecasts, scenarios and projections relate to, among other things, the long-term objectives of Noble Corporation plc (“Noble” or the “Company”), those regarding future guidance, revenue, adjusted EBITDA, the offshore drilling market and demand fundamentals, realization and timing of integration synergies, capital additions, costs, the benefits or results of acquisitions or dispositions such as the acquisition of Diamond Offshore Drilling, Inc. (the “Diamond Transaction”), free cash flow expectations, capital expenditures, including planned dividends and share repurchases, contract backlog, rig demand, expected future contracts, anticipated contract start dates, major project schedules, dayrates and duration, any asset sales or the retirement of rigs, access to capital, fleet condition and utilization, timing and amount of insurance recoveries and 2025 financial guidance. 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,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “on track,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would,” “achieve,” “shall,” “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 and uncertainties include, but are not limited to, 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, including, but not limited to, risks related to the recently completed Diamond Transaction, including the risk that the benefits of the transaction may not be fully realized or may take longer to realize than expected. 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 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. 2
