These forward-looking statements include, among other things, statements about guidance for the full-years ended December 31, 2017 and ending December 31, Although we believe that the expectations reflected in those forward-looking statements are reasonable, we can give no assurance that those expectations will prove to have been correct. Those statements are made by using various underlying assumptions and are subject to numerous risks, contingencies and uncertainties, including, among others: the ability to obtain the regulatory and shareholder approvals necessary to complete the proposed combination on the proposed timeline or at all; the risk that a condition to the closing of the proposed combination may not be satisfied or that the proposed combination may fail to close, including as the result of any inability to obtain the financing for the combination; the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted relating to the proposed combination; the costs incurred to consummate the proposed combination; the possibility that the expected synergies from the proposed combination will not be realized, or will not be realized within the expected time period; difficulties related to the integration of the two companies, the credit ratings of the combined businesses following the proposed combination; disruption from the proposed combination making it more difficult to maintain relationships with customers, employees, regulators or suppliers; the diversion of management time and attention on the proposed combination; adverse changes in the markets in which McDermott operates or credit markets, the inability of McDermott to execute on contracts in backlog successfully, changes in project design or schedules, the availability of qualified personnel, changes in the terms, scope or timing of contracts, contract cancellations, change orders and other modifications and actions by customers and other business counterparties of McDermott; or changes in industry norms and adverse outcomes in legal or other dispute resolution proceedings. If one or more of these risks materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. You should not place undue reliance on forward looking statements. For a more complete discussion of these and other risk factors, please see McDermott s annual and quarterly filings with the SEC, including its annual report on Form 10-K for the year ended December 31, 2016 and

24 Exhibit 99.1 FOR IMMEDIATE RELEASE McDermott Updates 2017 Guidance and Issues 2018 Guidance HOUSTON January 24, 2018 McDermott International, Inc. (NYSE: MDR) ( McDermott, the Company, or we ) is updating 2017 guidance and issuing 2018 guidance. Updated Full Year 2017 Guidance Updated Full Year 2017 Guidance ($ in millions, except as indicated) Revenues ~$3.0B Operating Income $ Operating Margin 10.7% % Net Income1 $ Diluted Income Per Share $ Debt Measures Ending Cash, Restricted Cash and Cash Equivalents $ Ending Gross Debt2 ~$540 Other Financial Measures Order Intake ~$2.6B EBITDA3 $ Capex $ ~ = approximately 1 McDermott s forecasted net income attributable to McDermott reflects an estimate of the 2017 year-end pension actuarial gain or loss and certain transaction-related costs associated with the proposed combination with CB&I. 2 Ending Gross Debt excludes debt issuance costs and capital lease obligations. 3 The calculation of EBITDA, which is a Non-GAAP measure, is shown in the appendix entitled Reconciliation of Forecast Non-GAAP Financial Measures to GAAP Financial Measures. The 2017 full year guidance updated above is being increased from the guidance included in McDermott s third quarter 2017 earnings release issued on November 1, 2017, due to strong operational performance, cost savings and better than anticipated weather and change orders during the fourth quarter of 2017.

25 Full Year 2018 Guidance Full Year 2018 Guidance ($ in millions, except as indicated) Revenues $3.1B - 3.3B Operating Income $ Operating Margin 7.9% - 8.3% Net Income1 $ Diluted Income Per Share $ Debt Measures Ending Cash, Restricted Cash and Cash Equivalents $ Ending Gross Debt2 ~$515 Other Financial Measures EBITDA3 $ Capex $ ~ = approximately 1 McDermott s forecasted net income attributable to McDermott does not include any amount representing 2018 year-end pension actuarial gain or loss, because the company has no basis to estimate pension actuarial gain or loss amounts for the forecast period and cannot estimate such amount without unreasonable effort. 2 Ending Gross Debt excludes debt issuance costs and capital lease obligations. 3 The calculation of EBITDA, which is a Non-GAAP measure, is shown in the appendix entitled Reconciliation of Forecast Non-GAAP Financial Measures to Forecast GAAP Financial Measures. McDermott s full year 2018 guidance differs from the Forward-Looking Financial Information referenced in the Registration Statement on Form S-4 (the Form S-4 ), which was filed with the U.S. Securities and Exchange Commission today. The differences are mainly attributable to McDermott s adoption, as of January 1, 2018, of ASU , Revenue from Contracts with Customers (ASC 606), and the Company s assessment of the impact of the policy change on future Consolidated Financial Statements. McDermott s updated guidance also reflects the evolution of the Company s internal forecasts and the timing of contracts awarded during the fourth quarter of McDermott s Forward-Looking Financial Information included in the Form S-4 was made available, in whole or in part, to the McDermott Board of Directors, the Supervisory and Management Boards of CB&I, and the financial advisors for each company in connection with their respective evaluations of the Combination. The Forward-Looking Financial Information was not prepared with a view toward public disclosure or with a view toward complying with GAAP. The Forward-Looking Financial Information does not reflect the January 1, 2018, adoption of ASU , Revenue from Contracts with Customers (ASC 606), or McDermott s updated outlook. McDermott is currently finalizing its assessment of the impact of the adoption of the new revenue recognition standard on the Company s future Consolidated Financial Statements and related disclosures. The adoption will result in the following changes to McDermott s revenue recognition policy: McDermott will measure transfer of control utilizing an input method to measure progress for individual contracts or combinations of contracts based on the total cost of materials, labor, equipment and vessel operating costs and other costs incurred as applicable to each contract

26 (often referred to as the Full Cost method). Prior to the adoption of the new standard, certain costs, such as significant costs for materials and third-party subcontractors, were excluded from the cost-to-cost method of measuring progress for revenue recognition (which the Company has historically referred to as the Partial Cost method), which resulted in the recognition of an asset related to cost incurred in excess of cost recognized. Variable consideration, including change orders, claims, bonus, incentive fees and liquidated damages or penalties will be included in the estimated contract revenue at the most likely amount to which McDermott expects to be entitled. The company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Prior to the adoption of the new standard, in certain circumstances estimated contract revenue was limited to amounts equal to costs expected to be incurred. McDermott intends to adopt the new standard on January 1, 2018, retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application ( modified retrospective application ), with no restatement of the comparative periods presented and a cumulative effect adjustment to retained earnings as of the date of adoption. This cumulative adjustment will result in a reduction of reported backlog for the year ended December 31, Further disclosure on the impact of adoption will be provided in our Annual Report on Form 10-K once filed.

To learn more, please visit our website at Non-GAAP Measures This press release includes non-gaap financial measures as defined under Regulation G of the U.S. Securities Exchange Act of 1934, as amended. We report our financial results in accordance with GAAP, but believe that certain non-gaap financial measures provide useful supplemental information to investors regarding the underlying business trends and performance of our ongoing operations and are useful for period-over-period comparisons of those operations. The forecast non-gaap measures we have presented in this press release include forecast EBITDA amounts. We believe these forward-looking financial measures are within reasonable measure. We define EBITDA as net income plus depreciation and amortization, interest expense, net, and provision for income

27 taxes. We have included EBITDA disclosures in this press release because EBITDA is widely used by investors for valuation and comparing our financial performance with the performance of other companies in our industry. Our management also uses EBITDA to monitor and compare the financial performance of our operations. EBITDA does not give effect to the cash that we must use to service our debt or pay our income taxes, and thus does not reflect the funds actually available for capital expenditures, dividends or various other purposes. Our presentation of EBITDA may not be comparable to similarly titled measures in other companies reports. You should not consider EBITDA in isolation from, or as a substitute for, net income or cash flow measures prepared in accordance with U.S. GAAP. Reconciliations of forecast EBITDA amounts to the most comparable GAAP measures are provided in the tables set forth at the end of this press release. Forward-Looking Statements In accordance with the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995, McDermott cautions that statements in this press release which are forward-looking, and provide other than historical information, involve risks, contingencies and uncertainties that may impact McDermott s actual results of operations. These forward-looking statements include, among other things, statements about McDermott s earnings and other guidance for 2017 and 2018 and expectations related to the guidance. Although we believe that the expectations reflected in those forward-looking statements are reasonable, we can give no assurance that those expectations will prove to have been correct. Those statements are made by using various underlying assumptions and are subject to numerous risks, contingencies and uncertainties, including, among others: adverse changes in the markets in which we operate or credit markets, our inability to execute on contracts in backlog successfully, changes in project design or schedules, the availability of qualified personnel, changes in the terms, scope or timing of contracts, contract cancellations, change orders and other modifications and actions by our customers and other business counterparties, changes in industry norms and adverse outcomes in legal or other dispute resolution proceedings. If one or more of these risks materialize, or if underlying assumptions prove incorrect, actual results may vary materially from those expected. You should not place undue reliance on forward-looking statements. For a more complete discussion of these and other risk factors, please see McDermott s annual and quarterly filings with the Securities and Exchange Commission, including its annual report on Form 10-K for the year ended December 31, 2016 and subsequent quarterly reports on Form 10-Q. This press release reflects management s views as of the date hereof. Except to the extent required by applicable law, McDermott undertakes no obligation to update or revise any forward-looking statement.
