Forward-Looking Statements

This communication includes “forward-looking statements” within the meaning of U.S. federal securities laws, including Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act, of 1934, as amended. You can identify these statements and other forward-looking statements in this document by words such as “expects,” “continue,” “focus,” “intends,” “anticipates,” “plans,” “targets,” “poised,” “advances,” “drives,” “aims,” “forecasts,” “believes,” “approaches,” “seeks,” “schedules,” “estimates,” “positions,” “pursues,” “progress,” “may,” “can,” “could,” “should,” “will,” “budgets,” “possible,” “outlook,” “trends,” “guidance,” “commits,” “on track,” “objectives,” “goals,” “projects,” “strategies,” “opportunities,” “potential,” “ambitions,” “aspires” and similar expressions, and variations or negatives of these words, but not all forward-looking statements include such words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the pending transaction between Noble and Diamond (the ”Transaction”), including the expected time period to consummate the Transaction, and the anticipated benefits (including synergies and free cash flow accretion) of the Transaction, and planned dividends. All such forward-looking statements are based upon current plans, estimates, expectations and ambitions that are subject to risks, uncertainties and assumptions, many of which are beyond the control of Noble and Diamond, that could cause actual results to differ materially from those expressed in such forward-looking statements. Key factors that could cause actual results to differ materially include, but are not limited to the risk that regulatory approval in Australia is not obtained or are obtained subject to conditions that are not anticipated by Noble and Diamond; uncertainties as to whether the Transaction will be consummated on the anticipated timing or at all, or if consummated, will achieve its anticipated economic benefits; Noble’s ability to integrate Diamond’s operations in a successful manner and in the expected time period; the possibility that any of the anticipated benefits and projected synergies of the Transaction will not be realized or will not be realized within the expected time period; the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement; risks that the anticipated tax treatment of the Transaction is not obtained; unforeseen or unknown liabilities; customer, shareholder, regulatory and other stakeholder approvals and support; unexpected future capital expenditures; potential litigation relating to the Transaction that could be instituted against Noble or Diamond or their respective directors; the possibility that the Transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the effect of the pendency or completion of Transaction on the parties’ business relationships and business generally; risks that the Transaction disrupts current plans and operations of Noble or Diamond, as well as the risk of disruption of Noble’s or Diamond’s management and business disruption during the pendency of, or following, the Transaction; changes in commodity prices; negative effects of the announcement of the Transaction, and the pendency or completion of the Transaction on the market price of Noble’s or Diamond’s common stock and/or operating results; rating agency actions and Noble’s and Diamond’s ability to access debt markets on a timely and affordable basis; decline in the price of oil or gas, reduced demand for oil and gas products and increased regulation of drilling and production, price competition and cyclicality in the offshore drilling industry, offshore rig supply, dayrates and demand for rigs, contract duration, renewal, terminations and repricing,

Other unpredictable or factors not discussed in this communication could also have material adverse effects on forward-looking statements. Neither Noble nor Diamond assumes an obligation to update any forward-looking statements, except as required by law. You are cautioned not to place undue reliance on any of these forward-looking statements as they are not guarantees of future performance or outcomes and that actual performance and outcomes. These forward-looking statements speak only as of the date hereof. 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 will be declared or continued.
