Item 1.01

Entry into a Material Definitive Agreement.

Nabors Energy Transition Corp. II (the “Company”) previously announced a proposed business combination with e2Companies LLC, a Florida limited liability company (“e2”).

On September 17, 2025, the Company issued an unsecured promissory note to Nabors Lux 2 S.a.r.l., a private limited liability company (société à responsabilité limitée) incorporated in the Grand Duchy of Luxembourg (“Nabors Lux”), an affiliate of Nabors Energy Transition Sponsor II LLC (the “Sponsor”), in the principal amount of $250,000 (the “Note”) in connection with the Extension (as defined below). The Note bears no interest and is due and payable upon the earlier to occur of (i) the date on which the Company consummates its initial business combination and (ii) the liquidation of the Company on or before October 19, 2025, unless such date is extended pursuant to the Company’s second amended and restated memorandum and articles of association (the “Amended Articles”), or such later liquidation date as may be approved by the Company’s shareholders.

If the Company consummates an initial business combination, it will repay the loan out of the proceeds of the trust account for its public shareholders (the “Trust Account”) or, at the option of the Sponsor, convert all or a portion of the loan into warrants for $1.00 per warrant, which warrants will be identical to the warrants issued by the Company in a private placement in connection with the Company’s initial public offering. If the Company does not consummate an initial business combination, the Company will repay the loan only from funds held outside of the Trust Account.

The issuance of the Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

The foregoing description of the Note is qualified in its entirety by reference to the full text of the Note, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Item 2.03

Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Item 8.01

Other Events.

On September 17, 2025, the Company issued a press release announcing that the Company’s board of directors has elected to extend the date by which the Company has to consummate an initial business combination from September 18, 2025 to October 18, 2025 (the “Extension”), as permitted under the Amended Articles. In connection with the Extension, Nabors Lux has deposited $250,000 into the Trust Account.

A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Company and e2 also plan to file other documents with the SEC regarding the Transactions. After the Registration Statement has been declared effective by the SEC, a definitive proxy statement/consent solicitation statement/prospectus will be mailed to the shareholders of the Company and unitholders of e2. INVESTORS AND SECURITY HOLDERS OF THE COMPANY AND E2 ARE URGED TO READ THE REGISTRATION STATEMENT, THE PROXY STATEMENT/CONSENT SOLICITATION STATEMENT/PROSPECTUS CONTAINED THEREIN (INCLUDING ALL AMENDMENTS AND SUPPLEMENTS THERETO) AND ALL OTHER DOCUMENTS RELATING TO THE TRANSACTIONS THAT WILL BE FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE TRANSACTIONS.

Participants in the Solicitation

Forward-Looking Statements

The information included herein and in any oral statements made in connection herewith include “forward-looking statements”. All statements, other than statements of present or historical fact included herein, regarding the Transactions, the Company’s and e2’s ability to consummate the Transactions, the benefits of the Transactions and the Company’s and e2’s future financial performance following the Transactions, as well as the Company’s and e2’s strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used herein, including any oral statements made in connection herewith, the words “could,” “should,” “will,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on the Company and e2 management’s current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Except as otherwise required by applicable law, the Company and e2 disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date hereof. The Company and e2 caution you that these forward-looking statements are subject to risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of the Company and e2. These risks include, but are not limited to, general economic, financial, legal, political and business conditions and changes in domestic and foreign markets; the inability of the parties to successfully or timely consummate the Transactions or to satisfy the conditions to the closing of the Transactions, including satisfaction of the minimum proceeds condition and the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company; the risk that the approval of the shareholders of the Company for the Transactions is not obtained; the failure to realize the anticipated benefits of the Transactions, including as a result of a delay in consummating the Transactions or difficulty in, or costs associated with, integrating the businesses of the Company and e2; the amount of redemption requests made by the Company’s shareholders; the outcome of any current or future legal proceedings or regulatory investigations, including any that may be instituted against the Company or e2 following announcement of the Transactions; the occurrence of events that may give rise to a right of one or both of the Company and e2 to terminate the definitive agreements related to the Transactions; difficulties or delays in the development of e2’s business; the risks related to the rollout of e2’s business and the timing of expected business milestones; potential benefits and commercial attractiveness to its customers of e2’s products; the potential success of e2’s marketing and expansion strategies; the effects of competition on e2’s future business; the ability of e2 to convert its currently contracted revenues from new original equipment manufacturer sales and energy service agreements into actual revenue; the ability of e2 to recruit and retain key executives, employees and consultants; and the ability of e2 management to successfully manage a public company. Should one or more of the risks or uncertainties described herein and in any oral statements made in connection therewith occur, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed in any forward-looking statements. Additional information concerning these and other factors that may impact the Company’s expectations can be found in the Company’s periodic filings with the SEC, including the Company’s Annual Report on Form 10-K/A filed with the SEC on April 2, 2025 and any subsequently filed Quarterly Reports on Form 10-Q.
