Item 1.01.

Entry into a Material Definitive Agreement.

On June 9, 2024, Diamond Offshore Drilling, Inc., a Delaware corporation (“Diamond Offshore”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Noble Corporation plc, a public limited company incorporated under the laws of England and Wales (“Noble”), Dolphin Merger Sub 1, Inc., a Delaware corporation and indirect wholly owned subsidiary of Noble (“Merger Sub 1”), and Dolphin Merger Sub 2, Inc., a Delaware corporation and indirect wholly owned subsidiary of Noble (“Merger Sub 2”).

The Merger Agreement provides that, among other things and subject to the terms and conditions of the Merger Agreement, (1) Merger Sub 1 will merge with and into Diamond Offshore, with Diamond Offshore surviving as a wholly-owned indirect subsidiary of Noble (the “First Merger” and the effective time thereof, the “First Merger Effective Time”), and the subsequent merger of Diamond Offshore, as the surviving entity in the First Merger, with and into Merger Sub 2, with Merger Sub 2 surviving as an indirect wholly-owned subsidiary of Noble (the “Second Merger” and, together with the First Merger, the “Mergers” and the effective time thereof, the “Effective Time”), and (2) at the First Merger Effective Time, each outstanding share of common stock of Diamond Offshore (other than any Cancelled Shares and any Appraisal Shares (each as defined in the Merger Agreement)) will be converted into the right to receive the following consideration (collectively, the “Merger Consideration”): (i) $5.65 in cash, without interest, payable to the holders of Diamond Offshore common stock (the “Per Share Cash Consideration”), (ii) 0.2316 (the “Exchange Ratio”) ordinary shares of Noble and (iii) any cash in lieu of fractional ordinary shares of Noble.

The Merger Agreement also specifies the treatment of outstanding Diamond Offshore warrants and Diamond Offshore equity awards in connection with the Mergers, which shall be treated as follows:

•

At the First Merger Effective Time, each outstanding and unexercised warrant of Diamond Offshore will be 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, if the holders of the warrants of Diamond Offshore 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.

•

At the First Merger Effective Time, each outstanding restricted stock unit award of Diamond Offshore will be converted into the number of ordinary shares of Noble equal to the product of (1) the number of shares of Diamond Offshore common stock subject to such restricted stock unit award immediately prior to the First Merger Effective Time and (2) the Equity Award Exchange Ratio (as defined below); provided, however, that any resulting fractional ordinary shares of Noble will be exchanged for cash. The “Equity Award Exchange Ratio” will be equal to the sum of (a) the Exchange Ratio plus (b) the quotient of (x) the Per Share Cash Consideration, divided by (y) the closing price on the New York Stock Exchange (“NYSE”) for an ordinary share of Noble on the last trading day immediately preceding the Effective Time.

•

At the Effective Time, each performance-vesting restricted stock unit award of Diamond Offshore will vest and be converted into the right to acquire the product of (1) the number of shares of Diamond Offshore common stock subject to the restricted stock unit awards of Diamond Offshore immediately prior to the Effective Time reflecting achievement of the applicable performance metrics at the greater of (i) the performance level determined in accordance with the performance criteria as otherwise provided in the applicable award agreement, and (ii) the target performance level under the terms of the Company Equity Plan (as defined in the Merger Agreement) and the applicable award agreement multiplied by and (2) the Equity Award Exchange Ratio; provided that any resulting fractional ordinary shares of Noble will rounded to the nearest whole share, subject to certain adjustments for performance-vesting restricted stock unit awards granted after the date of the Merger Agreement.

The board of directors of Diamond Offshore has unanimously (1) determined that the Merger Agreement and the transactions contemplated thereby, including the First Merger, are fair to, and in the best interests of, Diamond Offshore and the holders of Diamond Offshore’s common stock, (2) approved and declared advisable the Merger Agreement and the transactions contemplated thereby, including the First Merger, and (3) resolved to recommend that the Diamond Offshore stockholders approve and adopt the Merger Agreement.

The completion of the Mergers is subject to satisfaction or waiver of certain customary mutual closing conditions, including (1) the receipt of the required approvals from Diamond Offshore stockholders, (2) the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (3) certain other antitrust approvals having been obtained, (4) the absence of any governmental order or law that makes consummation of the Mergers illegal or otherwise prohibited, (5) the effectiveness of the registration statement on Form S-4 to be filed by Noble pursuant to which the ordinary shares of Noble to be issued in connection with the Mergers are registered with the Securities and Exchange Commission (the “SEC”), and (6) the authorization for listing of ordinary shares of Noble to be issued and reserved for issuance in connection with the Mergers on the NYSE. The obligation of each party to consummate the Mergers is also conditioned upon (1) the other party’s representations and warranties being true and correct (subject to certain materiality exceptions), (2) the other party having performed in all material respects its obligations under the Merger Agreement, (3) the absence of a material adverse effect on the other party and (4) the receipt of an officer’s certificate from the other party to such effect.

The Merger Agreement contains customary representations and warranties of Diamond Offshore and Noble relating to their respective businesses, financial statements and public filings, in each case generally subject to customary materiality qualifiers. Additionally, the Merger Agreement provides for customary pre-closing covenants of Diamond Offshore and Noble, including, subject to certain exceptions, covenants relating to conducting their respective businesses in the ordinary course consistent with past practice, and to refrain from taking certain actions without the other party’s consent. Diamond Offshore and Noble also agreed to use their respective reasonable best efforts to cause the Mergers to be consummated, to obtain expiration or termination of the waiting period under the HSR Act and to obtain certain other antitrust approvals, subject to certain limitations set forth in the Merger Agreement.

The Merger Agreement provides that, during the period from the date of the Merger Agreement until the Effective Time, Diamond Offshore will be subject to certain restrictions on its ability to solicit alternative transaction proposals from third parties and to engage in discussions with third parties regarding alternative transaction proposals, subject to customary exceptions. Diamond Offshore is required to call a meeting of its stockholders to approve the Merger Agreement and the other transactions contemplated thereby and, subject to certain exceptions, to recommend that its stockholders approve the Merger Agreement and the other transactions contemplated thereby.

The Merger Agreement contains customary termination rights for each of Diamond Offshore and Noble, including, among others, if the consummation of the Mergers do not occur on or before June 9, 2025 (subject to two potential extensions to December 9, 2025 and June 9, 2026 if the required regulatory approvals have not been received but all other conditions to closing have been satisfied or waived (except for those conditions that by their nature are to be satisfied at closing)) (such date, as may be extended pursuant to the Merger Agreement, the “end date”). Additionally, the Merger Agreement permits Diamond Offshore, subject to compliance with certain requirements and payment of a termination fee (described below), to terminate the Merger Agreement to enter into a definitive agreement for a superior alternative transaction proposal than the Mergers.

In the event that (a) the Merger Agreement is terminated in connection with (x) a failure to close the Mergers by the end date, (y) a failure of Diamond Offshore’s stockholders to approve the Mergers or (z) a breach by Diamond Offshore of its representations, warranties and covenants that results in the failure of the applicable closing conditions relating thereto, (b) a Company Alternative Proposal (as defined in the Merger Agreement) is publicly disclosed or announced prior to the Diamond Offshore stockholder meeting and (c) within 12 months of such termination, any transaction constituting a Company Alternative Proposal is consummated or an agreement providing for any Company Alternative Proposal is executed; then Diamond Offshore shall pay Noble a termination fee of $60,000,000. In the event that (1) Diamond Offshore terminates the Merger Agreement to enter into a definitive agreement for a superior alternative transaction proposal than the Mergers; (2) Noble terminates the

Merger Agreement in the event of a change of recommendation by the Diamond Offshore board of directors; or (3) the Merger Agreement is terminated by Diamond Offshore or Noble in the event of a failure of Diamond Offshore’s stockholders to approve the Mergers; then Diamond Offshore shall pay Noble a termination fee of $60,000,000 in the case of clauses (1) and (2), and $16,500,000 in the case of clause (3). In no event will Noble be entitled to receive more than one termination fee.

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

The Merger Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about Diamond Offshore. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement as of the specific dates therein, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Diamond Offshore’s public disclosures.
