Item 2.01 Completion of Acquisition or Disposition of Assets.

As discussed in the Introductory Note, on September 4, 2024, Noble completed its previously announced acquisition of the Company. At the First Merger Effective Time, subject to certain exceptions:

•

each share of common stock, par value $0.0001 per share, of Diamond Offshore (“Diamond Offshore Common Stock”) issued and outstanding immediately prior to the First Merger Effective Time (other than any shares of Diamond Offshore Common Stock (i) owned by Diamond Offshore, Merger Sub 1, Merger Sub 2 or Noble or (ii) for which holders have demanded their rights to be paid the fair value of such share of Diamond Offshore Common Stock in accordance with Section 262 of the Delaware General Corporation Law, was converted into the right to receive the following (collectively, the “Merger Consideration”): (a) $5.65 in cash, without interest, payable to the holder of each share of Diamond Offshore Common Stock (the “Per Share Cash Consideration”); (b) 0.2316 (the “Exchange Ratio”) of validly issued, fully paid and non-assessable A ordinary shares, $0.00001 nominal value per share, of Noble (“Noble Ordinary Shares”); and (c) any cash in lieu of fractional Noble Ordinary Shares to be paid pursuant to the Merger Agreement;

•

each outstanding and unexercised warrant of Diamond Offshore (“Diamond Offshore Warrants”) was assumed by Noble and for 90 days after the Effective Time will remain outstanding and during such 90-day period will be exercisable for the Merger Consideration to which the holders would have been entitled upon consummation of the First Merger, as if the holders of the Diamond Offshore Warrants had exercised the warrants in full immediately prior to the First Merger Effective Time and acquired the applicable number of shares of Diamond Offshore Common Stock then issuable upon exercise of such warrants as a result of such exercise (without taking into account any limitations or restrictions on the exercisability of the Diamond Offshore Warrants but taking into account the payment of the Warrant Exercise Price (as defined in the Warrant Agreement) (or exercise on a “cashless basis”)); and

•

each then outstanding performance-vesting restricted stock unit (a “PSU”) or time-vesting restricted stock unit (an “RSU”) covering shares of Diamond Offshore Common Stock (each, a “Diamond Offshore PSU” and a “Diamond Offshore RSU”, respectively) ceased to represent a right to receive shares of Diamond Offshore Common Stock (or value equivalent to shares of Diamond Offshore Common Stock) and was converted into the right to acquire a number of Noble Ordinary Shares equal to the product of (i) the number of shares of Diamond Offshore Common Stock subject to such Diamond Offshore PSU or Diamond Offshore RSU, as applicable, immediately prior to the First Merger Effective Time and (ii) the sum of (a) the Exchange Ratio plus (b) the quotient of (1) the Per Share Cash Consideration, divided by (2) the closing price on the New York Stock Exchange (the “NYSE”) for a Noble ordinary share on the last trading day immediately preceding the Effective Time. Under this formula, Diamond Offshore PSUs were converted into RSUs covering Noble Ordinary Shares (“Noble RSUs”) based on the greater of (x) actual Diamond Offshore performance level achieved and (y) target Diamond Offshore performance level, in each case, as determined under the performance criteria applicable to such Diamond Offshore PSUs, which Noble RSUs will otherwise vest on the same terms and conditions as were applicable under the Diamond Offshore PSUs, subject to certain adjustments for Diamond Offshore PSUs granted after the date of the Merger Agreement. Notwithstanding the foregoing, to the extent that a Diamond Offshore PSU or a Diamond Offshore RSU vested as of the First Merger Effective Time (including any awards that vest as a result of a termination of employment at or immediately after the Effective Time), such awards were instead settled in cash or shares of Diamond Offshore Common Stock, as applicable, immediately prior to the First Merger Effective Time and any such shares of Diamond Offshore Common Stock were treated the same as other shares of Diamond Offshore Common Stock, as explained above.

The issuance of Noble Ordinary Shares in connection with the Mergers was registered under the Securities Act of 1933, as amended, pursuant to Noble’s registration statement on Form S-4, as amended (File No. 333-280726), which was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on July 25, 2024. The proxy statement/prospectus included in the registration statement contains additional information about the Mergers.

The foregoing description of the Mergers and the Merger Agreement, and the transactions contemplated thereby, is a summary only, does not purport to be complete and is subject to and qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 2.01.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

Prior to the completion of the Mergers, shares of Diamond Offshore Common Stock were listed and traded on the NYSE under the trading symbol “DO”. In connection with the completion of the Mergers, the Company notified the NYSE that each eligible and outstanding share of Diamond Offshore Common Stock was converted into the right to receive the Merger Consideration and requested that the NYSE withdraw the listing of the Diamond Offshore Common Stock. In connection with the completion of the Mergers, the NYSE filed a notification of removal from listing on Form 25 with the SEC with respect to the delisting of the Diamond Offshore Common Stock and the deregistration of the Diamond Offshore Common Stock under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Diamond Offshore Common Stock ceased being traded prior to the opening of the market on September 4, 2024, and is no longer listed on the NYSE.

In addition, Noble Offshore Drilling, Inc., as successor in interest to the Company, intends to file with the SEC a Form 15 requesting that the reporting obligations of the Company under Sections 13(a) and 15(d) of the Exchange Act be suspended.

Item 3.03 Material Modification to Rights of Security Holders.

The information set forth in the Introductory Note, Item 1.01, Item 1.02, Item 2.01, Item 3.01 and Item 5.03 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.

At the First Merger Effective Time, each eligible share of Diamond Offshore Common Stock was converted into the right to receive the Merger Consideration.

Item 5.01 Changes in Control of Registrant.

At the First Merger Effective Time, the Company became a wholly owned subsidiary of Noble. At the Effective Time, all the property, rights, privileges, agreements, powers and franchises, debts, liabilities, duties and obligations of the Company and Merger Sub 2 became the property, rights, privileges, agreements, powers and franchises, debts, liabilities, duties and obligations of Merger Sub 2, which is a wholly owned subsidiary of Noble.

Prior to the Effective Time, Noble agreed to take all necessary actions to cause the Noble board of directors (the “Noble Board”), as of the First Merger Effective Time, to be increased by one director and to cause one individual who is, as of the date of the Merger Agreement, serving on the Diamond Offshore board of directors and mutually agreed by Diamond Offshore and Noble, to be appointed to the Noble Board immediately following the First Merger Effective Time.

The information set forth in the Introductory Note, Item 1.01, Item 2.01, Item 3.03, Item 5.02 and Item 5.03 of this Current Report on Form 8-K is incorporated by reference into this Item 5.01.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

In accordance with the terms of the Merger Agreement, each of the Company’s officers and directors forthwith resigned as an officer or director of the Company. These resignations were not a result of any disagreement between the Company and the officers and directors on any matter relating to the Company’s operations, policies or practices. At the Effective Time, Richard Barker, Jennie Howard and Craig Muirhead became the directors of Merger Sub 2, as the surviving entity in the Second Merger, and Mr. Barker became President, Ms. Howard became Secretary and Mr. Muirhead became Treasurer of Merger Sub 2, as the surviving entity in the Second Merger.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

In connection with the consummation of the Mergers, on September 4, 2024, the certificate of incorporation of Merger Sub 2 as in effect immediately prior to the Effective Time was amended and restated in its entirety as set forth in Exhibit 3.1 to this Current Report on Form 8-K, and the bylaws of Merger Sub 2 as in effect immediately prior to the Effective Time, as set forth in Exhibit 3.2 to this Current Report on Form 8-K, became the certificate of incorporation and bylaws of Merger Sub 2, as the surviving entity in the Second Merger. Immediately after the Effective Time, Merger Sub 2 was renamed “Noble Offshore Drilling, Inc.”, pursuant to a certificate of amendment to the amended and restated certificate of incorporation of Merger Sub 2 filed with the Secretary of State of the State of Delaware, a copy of which is attached as Exhibit 3.3 to this Current Report on Form 8-K.

The foregoing description is a summary only, does not purport to be complete and is subject to and qualified in its entirety by reference to Exhibits 3.1, 3.2 and 3.3 to this Current Report on Form 8-K and is incorporated by reference into this Item 5.03.
