Colleagues,

The first day of our combined business is quickly approaching. As you may know, the stockholders of McDermott and CB&I are scheduled to vote on the combination on May 2nd and we expect that the transaction will close shortly thereafter. That means Day One of our new organization would be only weeks away. As we continue the integration planning process, we wanted to highlight a few important topics.

We also wanted to reiterate what David Dickson said on Monday in his note regarding the unsolicited, non-binding proposal we received from Subsea 7. Everyone here at McDermott remains committed to completing our combination with CB&I. We understand that these kind of last-minute bids can be distracting, but want you to know that we are pushing ahead as planned and are counting on your continued focus and dedication to delivering for our customers as we work to complete this transformational combination.

Recognizing the Value of Our Combination

Over the past two weeks, three leading independent investor research firms, Institutional Shareholder Services (ISS), Glass Lewis and Egan-Jones, announced they agree with us about the strength of the McDermott-CB&I combination. This is important because many of our largest stockholders look to these firms for guidance and counsel on how to vote on transactions like ours.

In its report dated April 17, 2018, ISS states:

“The industrial logic of the deal is solid. The merger will help McDermott diversify geographically, adding exposure to the US market, and diversify the company’s client base. … The strategic rationale for the combination is sound, the valuation paid appears to be reasonable, offering upside potential to MDR shareholders, and management’s proven track record in turning around unprofitable projects suggests that execution should not be an issue.”


We are pleased that these firms recognize the significant value of our transformational combination and earlier this week ISS reaffirmed its recommendation following Subsea 7’s unsolicited bid.

Globally Integrated, Locally Focused

As we have previously announced, on Day One we would be organized by four Areas—North, Central & South America (NCSA); Europe, Africa, Russia & Caspian (EARC); Middle East & North Africa (MENA); and Asia Pacific (APAC). Each Area leader would be responsible for overseeing customer satisfaction, project delivery and profitability in their region. They would be supported by our global project delivery functions—including project management, engineering, supply chain, marine, fabrication, construction and QHSES—which would allocate the necessary resources for each project and customer.

The goal is for us to begin operating in this structure as soon as the transaction closes. Teams from project delivery and corporate functions have been meeting with the IMO to make sure that we are as ready as possible for the first day of our new company. Recently, representatives from the four Areas also joined the planning process.

Together, we are creating a new kind of company that can partner with our customers to provide integrated, end-to-end solutions—from the wellhead to the storage tank—that deliver the quality, efficiency and dependability needed to keep their businesses growing. I’m proud to say that we’re making excellent progress.

What Comes Next

Following the closing, we need to continue working together as we integrate our organizations, policies, procedures and systems. While we know that this process can be distracting and create uncertainty, we promise to keep you up to date as we continue to make progress and our new organization takes shape.

Thank you again for your continued support as the integration planning process moves forward. If you have any questions about integration planning, the combination of McDermott and CB&I or want to propose a future update topic, please send them to questions@mcdermott.com.

Best regards,

Tony and the IMO

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 and CB&I operate or credit markets; the inability of McDermott or CB&I 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 and CB&I; 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.
