DO Diamond Offshore Drilling Inc

Item 7.01. Regulation FD Disclosure

On August 30, 2016, a subsidiary of Diamond Offshore Drilling, Inc. (the “Company”) received notice of termination from Petróleo Brasileiro S.A. (“Petrobras”) of its drilling contract on the Ocean Valor . The drilling contract, which was extended in 2014, was estimated to conclude in accordance with its terms in October 2018. The Company does not believe that Petrobras had a valid or lawful basis for terminating the contract, and the Company intends to defend the rights of its subsidiary under the contract.

The Company hereby incorporates by reference into this Item 7.01 the summary report of the status, as of September 1, 2016, of the Company’s offshore drilling rigs attached as Exhibit 99.1.

The information contained in Item 7.01 and Exhibit 99.1 of this report shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and shall not be incorporated by reference into any previous or future registration statement filed under the Securities Act of 1933, as amended (the “Securities Act”), unless specifically identified therein as being incorporated by reference.

Statements made in this report or in the summary report furnished as Exhibit 99.1 to this report that are not historical facts are “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Such statements may include, but are not limited to, statements regarding the future term of the Petrobras drilling contract; the enforcement of the rights of the Company’s subsidiary under the Petrobras contract; drilling rig deliveries, operations and timing; contract effectiveness, effective dates and estimated duration; plans regarding retirement and scrapping of drilling rigs; expectations of future backlog, revenue, operating costs and performance; revenue expected to result from backlog; future dayrates, future status, start and end dates and future contracts and availability; future contract opportunities and termination rights; contract noncompliance by customers and other third parties; utilization, surveys, downtime and other aspects of the Company’s drilling rigs; customer discussions and outcomes thereof and the impact of these and related events on the Company’s operations and revenues; and other statements that are not of historical fact. Forward-looking statements are inherently uncertain and subject to a variety of assumptions, risks and uncertainties that could cause actual results to differ materially from those currently anticipated or expected by management of the Company. A discussion of the risk factors and other considerations that could materially impact these matters as well as the Company’s overall business and financial performance can be found in the Company’s reports filed with the Securities and Exchange Commission, and readers of this report are urged to review those reports carefully when considering these forward-looking statements. These risk factors include, among others, risks associated with worldwide demand for drilling services, level of activity in the oil and gas industry, renewing or replacing expired or terminated contracts, contract cancellations and terminations, maintenance and realization of backlog, and various other factors, many of which are beyond the Company’s control. Given these risk factors, investors and analysts should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of such statement, and the Company expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement to reflect any change in the Company’s expectations with regard thereto or any change in events, conditions or circumstances on which any forward-looking statement is based.
