Dear Nabors Energy Transition Corp. II Shareholder:

You are cordially invited to attend an extraordinary general meeting of Nabors Energy Transition Corp.

The Shareholder Meeting will be conducted via live webcast, but the physical location of the Shareholder Meeting will remain at the location specified above for the purposes of our currently effective Second Amended and Restated Memorandum and Articles of Association (the “ Second A&R Memorandum and Articles of Association ”). If you wish to attend the Shareholder Meeting in person, you must reserve your attendance at least two business days in advance of the Shareholder Meeting by contacting the Company’s Chief Executive Officer at 515 West Greens Road, Suite 1200, Houston, Texas 77067 by 4:00 p.m., Central Time, on November 12, 2025 (two business days prior to the initially scheduled meeting date). You can participate in the virtual Shareholder Meeting, vote and submit questions via live webcast by visiting https://www.cstproxy.com/naborsetcorpii/egm2025 . Please see “ Questions and Answers about the Shareholder Meeting — How do I attend the virtual Shareholder Meeting? ” in the accompanying proxy statement for more information. Even if you are planning on attending the Shareholder Meeting online, please promptly submit your proxy vote online, or, if you received a printed form of proxy in the mail, by completing, dating, signing and returning the enclosed proxy, so your shares will be represented at the Shareholder Meeting.

The accompanying notice of the Shareholder Meeting and proxy statement describe the business the Company will conduct at the Shareholder Meeting and provide information about the Company that you should consider when you vote your shares. As more fully described in the accompanying proxy statement, which is dated October 27, 2025, and is expected to be first mailed or otherwise delivered to shareholders on or about that date, the Shareholder Meeting will be held for the purpose of considering and voting on the following proposals:

Proposal No. 1 — Articles Amendment Proposal — To consider and vote upon a proposal to approve by special resolution, with effect from such date as determined by the Company’s board of directors (the “ Board ”) in their sole discretion, an amendment to the Second A&R Memorandum and Articles of Association to (i) delete Article 49 (Business Combination), other than Article 49.7, in its entirety and (ii) extend the date by which the Company has to consummate a merger, share exchange, asset acquisition, share purchase, reorganisation or similar business combination, involving the Company and one or more businesses or entities (an “ initial business combination ”) indefinitely (the “ Indefinite Extension ” and such proposal, the “ Articles Amendment Proposal ”).

The text of the special resolution and a copy of the form of the proposed Amendment to the Second Amended and Restated Memorandum and Articles of Association are set forth in Annex A to the accompanying proxy statement, which we refer to as the “ Articles Amendment ”.

Proposal No. 2 — IMTA Amendment Proposal — To consider and vote upon a proposal to approve an amendment and restatement of the Amended and Restated Investment Management Trust Agreement, dated as of July 17, 2025 (the “ Trust Agreement ”), by and between the Company and Continental Stock Transfer & Trust Company, as trustee, to permit the Company (i) to withdraw from the interest earned on the trust account (the “ Trust Account ”) established in connection with the Company’s initial public offering (the “ IPO ”) (x) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (y) up to 100% of the interest accrued from the date of the IMTA Amendment (as defined below), in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation and (ii) to reflect the Indefinite Extension (such proposal, the “ IMTA Amendment Proposal ”).

TABLE OF CONTENTS

A copy of the form of the proposed Second Amended and Restated Investment Management Trust Agreement, which we refer to as the “ IMTA Amendment ,” is set forth in Annex B to the accompanying proxy statement.

Proposal No. 3 — Adjournment Proposal — To consider and vote upon a proposal to approve by ordinary resolution the adjournment of the Shareholder Meeting to a later date or dates or indefinitely, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Shareholder Meeting, there are insufficient Class A ordinary shares, par value $0.0001 per share (the “ Class A Ordinary Shares ”), Class B ordinary shares, par value $0.0001 per share (the “ Class B Ordinary Shares ”), and Class F ordinary shares, par value $0.0001 per share (the “ Class F Ordinary Shares ” and, collectively with the Class A Ordinary Shares and the Class B Ordinary Shares, the “ Ordinary Shares ”), in the share capital of the Company represented (either in person, virtually or by proxy) at the time of the Shareholder Meeting to approve the Articles Amendment Proposal or the IMTA Amendment Proposal or if the Board otherwise determined before the Shareholder Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposal or the IMTA Amendment Proposal (such proposal, the “ Adjournment Proposal ” and, collectively with the Articles Amendment Proposal and the IMTA Amendment Proposal, the “ Proposals ”), in which case the Adjournment Proposal will be the only proposal presented at the Shareholder Meeting.

The text of the ordinary resolution is as follows:

“ RESOLVED , as an ordinary resolution, to adjourn the Shareholder Meeting to a later date or dates or indefinitely, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Shareholder Meeting, there are insufficient Class A ordinary shares, par value $0.0001 per share, Class B ordinary shares, par value $0.0001 per share, and Class F ordinary shares, par value $0.0001 per share, in the share capital of the Company represented (either in person, virtually or by proxy) at the time of the Shareholder Meeting to approve the Articles Amendment Proposal or the IMTA Amendment Proposal, or if the Board otherwise determined before the Shareholder Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposal or the IMTA Amendment Proposal.”

None of the Articles Amendment Proposal or the IMTA Amendment Proposal are conditioned on the approval of any of the other Proposals, and no other Proposal is conditioned on the approval of the Articles Amendment Proposal or the IMTA Amendment Proposal. If either the Articles Amendment Proposal or the IMTA Amendment Proposal is not approved, the Company may in the future ask shareholders to approve proposals similar to the Proposals. Nabors Energy Transition Sponsor II LLC (the “ Sponsor ”) has informed the Board that it does not intend to fund, nor does it intend to cause any of its affiliates or designees to fund, any further Monthly Extension Payments (as defined below). If any of the Proposals are not approved and future Monthly Extension Payments are not made, the Company may be wound up in accordance with the Second A&R Memorandum and Articles of Association (as may be amended). Each of the Proposals is more fully described in the accompanying proxy statement. Please take the time to read carefully each of the Proposals in the accompanying proxy statement before you vote.

On February 11, 2025, the Company and Liffey Merger Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company (“ Merger Sub ”), entered into the Business Combination Agreement and Plan of Reorganization (the “ Business Combination Agreement ” and the transactions contemplated therein, the “ e2 Business Combination ”) with e2Companies LLC, a Florida limited liability company (“ e2 ”).

On October 14, 2025 (the “ Settlement Date ”), the Company, e2, the Sponsor and Merger Sub entered into the Settlement Agreement and Release (the “ Settlement Agreement ”) pursuant to which (i) e2 issued a secured promissory note to the Company in an aggregate principal amount of $29.23 million, of which (x) $14.615 million matures on March 31, 2026 ($3.5 million of which is required to be prepaid on or before December 31, 2025) (the “ First Note ”), and (y) $14.615 million matures on October 14, 2028 (the “ Second Note ” and together with the First Note, the “ Notes ”), provided that, certain security interests granted by e2 and its subsidiaries will not vest until the repayment in full of all obligations owed to a priority creditor, (ii) the parties agreed to dismiss with prejudice the previously disclosed action styled Nabors Energy

TABLE OF CONTENTS

Transition Corp. II, et al. v. e2Companies LLC , 2025-0810-BWD (the “ Action ”) and release the parties from various known and unknown claims, subject to certain carve-outs, effective upon the Settlement Date, and (iii) the Business Combination Agreement and all ancillary agreements entered into in connection therewith were deemed terminated by mutual agreement upon the Settlement Date. Prior to the maturity date of the Second Note, upon the occurrence of a Payment Event (as defined below), (i) that is a change of control (other than a change of control of a Covered Entity (as defined below) formed to effect a sale of inventory that does not result in the transfer of more than 60% of the book value of e2’s consolidated total assets), each Note shall become due and payable in full, and (ii) that is not a change of control, a minimum of 50% of the net proceeds from any Payment Event directly received by a Covered Entity or its shareholders, successors or assigns in excess of a cumulative threshold of $17.5 million of the net proceeds from all Payment Events received by a Covered Entity or its shareholders, successors or assigns, shall be used to repay, in whole or in part, first the Second Note and then the First Note (but not more than the amount of the then-current principal plus accrued interest with respect to each Note) no later than three (3) business days following consummation of such Payment Event. Further, a minimum of 10% of the net proceeds from up to $22 million of debt or equity financings by a Covered Entity consummated on or prior to March 31, 2026, the sole use of the proceeds of which (after expenses attributable to the financing) is the repayment or refinancing of indebtedness outstanding as of the Settlement Date, shall be used to repay, in whole or in part, first the Second Note and then the First Note (but not more than the amount of the then-current principal plus accrued interest with respect to each Note) no later than three (3) business days following consummation of such financing. A “ Payment Event ” means the occurrence of one or more of the following events within three years from the Settlement Date: (i) a debt or equity financing by a Covered Entity (including an initial public offering), excluding a financing where the sole use of net proceeds (after expenses attributable to the financing) is (x) to finance the acquisition of equipment to be added to inventory or (y) to fund all or a portion of the payment of the Notes; (ii) a sale or exchange by a Covered Entity or its shareholders of any of its interest in a Covered Entity, whether directly or indirectly; (iii) a sale or exchange of assets constituting 20% or more of the book value of e2’s consolidated total assets as of the end of the most recently completed calendar quarter by a Covered Entity, other than the sale of inventory in the ordinary course of business; or (iv) a change of control of a Covered Entity. If the Company enters into a definitive agreement with respect to an initial business combination prior to the maturity date of the Second Note and such initial business combination is consummated, the remaining then-current principal amount of the Second Note shall be cancelled and no further interest shall continue to accrue. However, all interest accrued and unpaid with respect to the Second Note prior to but not including the date of the consummation of any initial business combination shall be due and payable from e2 in connection therewith. Any amount paid by e2 to the Company under the Second Note prior to the consummation of any initial business combination, shall not be required to be returned to e2.

Upon the consummation within 24 months from the Settlement Date of (i) a change of control of e2, Iepreneur Consulting, LLC or any of their respective subsidiaries, assigns and successors (each, a “ Covered Entity ”), (ii) an initial public offering of a Covered Entity or (iii) another event where the securities of a Covered Entity become publicly listed on a national securities exchange (each, a “ Trigger Event ”), e2 is required to make a cash payment to the Company in an amount equal to 6.5% of the portion of the equity value of e2 in excess of $500 million implied by such Trigger Event (such payment, the “ Trigger Event Payment ”). The Company intends to use the proceeds received from the Notes and Trigger Event Payment, if any, to satisfy its liabilities, obligations, fees and expenses incurred in connection with the transactions contemplated by the Business Combination Agreement and IPO and any excess may be distributed to the Company’s shareholders at the discretion of the Board. If, at the time of a Trigger Event, the Company has entered into a definitive agreement for an initial business combination, but such initial business combination has not yet been consummated, then any Trigger Event Payment shall instead be deposited by e2 into an escrow account. If such definitive agreement for an initial business combination is terminated, the Trigger Event Payment will be released to the Company, and if such initial business combination is consummated, the Trigger Event Payment will be released to e2. The terms of the Settlement Agreement and the Notes are described in further detail in the Current Report on Form 8-K filed by the Company with the U.S. Securities and Exchange Commission on October 15, 2025.

The Second A&R Memorandum and Articles of Association provides that the Company had until July 18, 2025, to consummate an initial business combination, subject to twelve one-month extensions to extend such date to July 18, 2026 (or within 36 months from the consummation of the IPO), provided that

TABLE OF CONTENTS

the Sponsor (or its affiliates or designees) deposits additional funds of $250,000 for each one-month extension (each such extension, a “ Monthly Extension Period ”) into the Trust Account in exchange for a non-interest bearing, unsecured promissory note (each such payment, a “ Monthly Extension Payment ”). The Board has previously elected to effectuate four one-month extensions to extend the date it has to complete its initial business combination (the “ Termination Date ”) from July 18, 2025 to November 18, 2025, and a total of $1.0 million has been deposited into the Trust Account, each in exchange for a non-interest bearing, unsecured promissory note. The Sponsor has informed the Board that it does not intend to fund, nor does it intend to cause any of its affiliates or designees to fund, any further Monthly Extension Payments. The Board believes it is in the best interests of the Company and its shareholders to provide for the continued existence of the Company even without the Monthly Extension Payments, and the Board currently anticipates maintaining the Company’s existence until all payments are made under the Settlement Agreement and the Notes. The purpose of the Articles Amendment Proposal is to allow the Company to remain in existence indefinitely to receive the payments under the Settlement Agreement and Notes and to remove the obligations under the Second A&R Memorandum and Articles of Association for the Sponsor (or its affiliates or designees) to make the Monthly Extension Payments. The purpose of the IMTA Amendment Proposal is to allow the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation. You are not being asked to vote on any initial business combination at this time .

The Board has determined that it is in the best interests of the Company to have the Company’s shareholders approve the Articles Amendment Proposal and the IMTA Amendment Proposal to allow the Company to remain in existence indefinitely to receive payments under the Settlement Agreement and Notes and to permit the Company to withdraw from the interest earned on Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation.

The Company reserves the right at any time to cancel the Shareholder Meeting (by means of holding and thereafter adjourning the Shareholder Meeting sine die or indefinitely) and to not submit the Articles Amendment Proposal or the IMTA Amendment Proposal to its shareholders. In the event the Shareholder Meeting is cancelled (by means of holding and thereafter adjourning the Shareholder Meeting sine die or indefinitely), unless the Sponsor (or its affiliate or designee) makes additional Monthly Extension Payments, the Company will wind up in accordance with the Second A&R Memorandum and Articles of Association.

As contemplated by the Second A&R Memorandum and Articles of Association, the holders of the Class A Ordinary Shares issued as part of the units sold in the IPO (the “ Public Shares ”) may elect to redeem all or a portion of their Public Shares (the “ Redemptions ”) in exchange for their pro rata portion of the funds held in the Trust Account as of two business days prior to the Shareholder Meeting if the Articles Amendment Proposal is implemented, regardless of whether or how such public shareholders vote in regard to such proposal. The Company may (and intends to) accept Redemptions in the event the Articles Amendment Proposal is not approved and the Articles Amendment Proposal is not implemented.

thereof, but there can be no assurances that such payments will be received in full or at all or as to the amount of fees and expenses of the Company, and any such distribution will be at the discretion of the Board. Up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment may be withdrawn from the interest earned on the Trust Account to pay fees and expenses incurred by or on behalf of the Company since its formation, including those incurred in connection with the Action, and the remainder of the funds will be held until the time the Company liquidates and dissolves as and when determined by the Board, at which time the remaining funds in the Trust Account will be used to redeem the holders of Public Shares remaining after the Redemption in connection with the Shareholder Meeting. As of the date of this proxy statement, the Company has (i) approximately $10.0 million of incurred fees and expenses and (ii) approximately $4.1 million in loans from the direct and indirect owners of the Sponsor and Monthly Extension Payments. The Company expects that following the Redemptions it will not meet the listing standards of The Nasdaq Stock Market LLC (“ Nasdaq ”) and, accordingly, expects to be delisted from Nasdaq. The Company will remain in existence indefinitely or until such time as the Board determines that the Company liquidate and dissolve. See the section entitled “ Risk Factors ” for an overview of risks relating to the settlement.

On October 23, 2025, the most recent practicable date prior to the date of the accompanying proxy statement, the redemption price per share was approximately $11.31, based on the aggregate amount on deposit in the Trust Account of approximately $155.3 million as of October 23, 2025 (including interest not previously released to the Company to pay taxes), divided by the total number of then outstanding Public Shares. The redemption price per share in connection with the Articles Amendment Proposal will be calculated based on the aggregate amount on deposit in the Trust Account two business days prior to the Shareholder Meeting. The closing price per Public Share on The Nasdaq Stock Market LLC on October 23, 2025, was $11.35. If the closing price of the Public Shares was to remain the same until the date of the Shareholder Meeting, exercising redemption rights would result in a public shareholder receiving approximately $0.04 less per share than if the shares were sold in the open market (based on the current per share redemption price as of October 23, 2025). The Company cannot assure shareholders that they will be able to sell their Public Shares in the open market, even if the market price per share is lower than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

If the Articles Amendment Proposal is not approved and an initial business combination is not completed on or before the Termination Date (subject to any Monthly Extension Periods), the Company will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account not previously released to the Company to pay its taxes (net of any taxes payable by the Company and less up to $100,000 of interest that may be released to the Company to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Board, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. In such an event, the Public Shares will have been redeemed, and will not be entitled to participate in any distribution of proceeds of payments under the Settlement Agreement or the Notes. There will be no distribution from the Trust Account with respect to the Company’s warrants, which will expire worthless in the event of our winding up.

The approval of the Articles Amendment Proposal requires a special resolution under Cayman Islands law, which is a resolution passed by a majority of at least two-thirds (2/3) of such shareholders of the Company as, being entitled to do so, vote in person or by proxy at the Shareholder Meeting. Pursuant to the Trust Agreement, the approval of the IMTA Amendment Proposal requires the affirmative vote of the holders of at least sixty-five percent (65%) of the issued and outstanding Ordinary Shares, voting together as a single class. Approval of the Articles Amendment Proposal is a condition to the implementation of the Articles Amendment, and approval of the IMTA Amendment Proposal is a condition to the implementation of the IMTA Amendment.

TABLE OF CONTENTS

The Board has fixed the close of business on October 20, 2025 as the date for determining the Company’s shareholders entitled to receive notice of and vote at the Shareholder Meeting and any adjournment thereof (the “ Record Date ”). Only holders of record of Ordinary Shares on that date are entitled to have their votes counted at the Shareholder Meeting or any adjournment thereof. A complete list of shareholders of record entitled to vote at the Shareholder Meeting will be available for 10 days before the Shareholder Meeting at the Company’s principal executive offices for inspection by shareholders during ordinary business hours for any purpose germane to the Shareholder Meeting.

The Company believes that it is in the best interests of the Company’s shareholders that the Company effect the Articles Amendment and the IMTA Amendment. After careful consideration of all relevant factors, the Board has determined that the Proposals are in the best interests of the Company and its shareholders, has declared it advisable and recommends that you vote or give instruction to vote “FOR” the Proposals.

Your vote is very important. Whether or not you plan to attend the Shareholder Meeting, please vote as soon as possible by following the instructions in the accompanying proxy statement to make sure that your shares are represented and voted at the Shareholder Meeting. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that your shares are represented and voted at the Shareholder Meeting. The approval of the Articles Amendment Proposal requires a special resolution under Cayman Islands law, which is a resolution passed by a majority of at least two-thirds (2/3) of such shareholders of the Company as, being entitled to do so, vote in person or by proxy at the Shareholder Meeting. Pursuant to the Trust Agreement, the approval of the IMTA Amendment Proposal requires the affirmative vote of the holders of at least sixty-five percent (65%) of the issued and outstanding Ordinary Shares, voting together as a single class. The approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, which is a resolution passed by a simple majority of the shareholders of the Company as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Shareholder Meeting. Accordingly, if you fail to vote in person, virtually or by proxy at the Shareholder Meeting, your shares will not be counted for the purposes of determining whether the Proposals are approved by the requisite majorities.

If you sign, date and return your proxy card without indicating how you wish to vote, your proxy will be voted “FOR” each of the proposals presented at the Shareholder Meeting. If you fail to return your proxy card or fail to instruct your bank, broker or other nominee how to vote, and do not attend the Shareholder Meeting virtually or in person, the effect will be, among other things, that your shares will not be counted for purposes of determining whether a quorum is present at the Shareholder Meeting but will not constitute votes cast at the Shareholder Meeting and therefore will have the same effect as a vote “AGAINST” the IMTA Amendment Proposal and no effect on the approval of the Articles Amendment Proposal and the Adjournment Proposal. You can also attend the Shareholder Meeting and vote in person or online. Even if you have previously voted by submitting a proxy pursuant to any of the methods noted above, you may withdraw your proxy and vote in person or online.

The Board has determined that it is in the best interests of the Company to have the Company’s shareholders approve the Articles Amendment Proposal and the IMTA Amendment Proposal to allow the Company to remain in existence indefinitely to receive payments under the Settlement Agreement and Notes and to permit the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation.

proceeds of the Trust Account, less (y) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment, and (ii) a pro rata portion (allocated among the Public Shares not redeemed and the Class F Ordinary Shares) of any payments under the Settlement Agreement and the Notes, net of fees and expenses paid or to be paid by or on behalf of the Company. We expect the Board will declare pro rata distributions of such net proceeds of payments under the Settlement Agreement and the Notes from time to time following receipt thereof, but there can be no assurances that such payments will be received in full or at all or as to the amount of fees and expenses of the Company, and any such distribution will be at the discretion of the Board. Up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment may be withdrawn from the interest earned on the Trust Account to pay fees and expenses incurred by or on behalf of the Company since its formation, including those incurred in connection with the Action, and the remainder of the funds will be held until the time the Company liquidates and dissolves as and when determined by the Board, at which time the remaining funds in the Trust Account will be used to redeem the holders of Public Shares remaining after the Redemption in connection with the Shareholder Meeting. As of the date of this proxy statement, the Company has (i) approximately $10.0 million of incurred fees and expenses and (ii) approximately $4.1 million in loans from the direct and indirect owners of the Sponsor and Monthly Extension Payments. The Company expects that following the Redemptions it will not meet the listing standards of The Nasdaq Stock Market LLC (“ Nasdaq ”) and, accordingly, expects to be delisted from Nasdaq. The Company will remain in existence indefinitely or until such time as the Board determines that the Company liquidate and dissolve. See the section entitled “ Risk Factors ” for an overview of risks relating to the settlement.

The Sponsor and the Company’s independent directors will not receive any amount of the funds held in the Trust Account as a result of their ownership of an aggregate of 7,625,000 Class F Ordinary Shares, and the direct and indirect owners of the Sponsor will not receive any amount of the funds held in the Trust

Account as a result of their ownership of an aggregate of 9,540,000 of the Company’s warrants, which were issued in connection with the IPO.

If the Company winds up, the Sponsor has agreed to indemnify us to the extent any claims by a third party for services rendered or products sold to us, or any claims by a prospective target business with which we have discussed entering into an acquisition agreement, reduce the amount of funds in the Trust Account to below (i) $10.10 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of interest withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to our Trust Account and except as to any claims under our indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. We cannot assure you, however, that the Sponsor would be able to satisfy those obligations. Based upon the current amount in the Trust Account, we anticipate that the per-share price at which Public Shares will be redeemed from cash held in the Trust Account will be approximately $11.31. Nevertheless, the Company cannot assure you that the per share distribution from the Trust Account, if the Company winds up, will not be less than $10.10, plus interest, due to unforeseen claims of creditors.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST DEMAND IN WRITING THAT YOUR CLASS A ORDINARY SHARES ARE REDEEMED FOR A PRO RATA PORTION OF THE FUNDS HELD IN THE TRUST ACCOUNT AND TENDER OR DELIVER YOUR SHARES (AND SHARE CERTIFICATES (IF ANY) AND OTHER REDEMPTION FORMS) TO THE COMPANY’S TRANSFER AGENT PRIOR TO 4:00 P.M. CENTRAL TIME ON THE DATE THAT IS TWO BUSINESS DAYS PRIOR TO THE INITIALLY SCHEDULED DATE OF THE SHAREHOLDER MEETING. IN ORDER TO EXERCISE YOUR REDEMPTION RIGHT, YOU NEED TO IDENTIFY YOURSELF AS A BENEFICIAL HOLDER AND PROVIDE YOUR LEGAL NAME, PHONE NUMBER AND ADDRESS IN YOUR WRITTEN DEMAND. YOU MAY TENDER OR DELIVER YOUR SHARES BY EITHER DELIVERING YOUR SHARE CERTIFICATE, IF ANY (AND OTHER REDEMPTION FORMS), TO THE TRANSFER AGENT OR BY DELIVERING YOUR SHARES ELECTRONICALLY USING THE DEPOSITORY TRUST COMPANY’S DEPOSIT WITHDRAWAL AT CUSTODIAN (DWAC) SYSTEM. IF YOU HOLD THE SHARES IN STREET NAME, YOU WILL NEED TO INSTRUCT THE ACCOUNT EXECUTIVE AT YOUR BANK OR BROKER TO WITHDRAW THE SHARES FROM YOUR ACCOUNT IN ORDER TO EXERCISE YOUR REDEMPTION RIGHTS. The approval of the Articles Amendment Proposal requires a special resolution under Cayman Islands law, which is a resolution passed by a majority of at least two-thirds (2/3) of such shareholders of the Company as, being entitled to do so, vote in person or by proxy at the Shareholder Meeting. Pursuant to the Trust Agreement, the approval of the IMTA Amendment Proposal requires the affirmative vote of the holders of at least sixty-five percent (65%) of the issued and outstanding Ordinary Shares, voting together as a single class. Approval of the Articles Amendment Proposal is a condition to the implementation of the Articles Amendment, and approval of the IMTA Amendment Proposal is a condition to the implementation of the IMTA Amendment.

Record holders of Ordinary Shares at the close of business on October 20, 2025 (the “ Record Date ”) are entitled to vote or have their votes cast at the Shareholder Meeting. On the Record Date, there were 13,724,863 issued and outstanding Class A Ordinary Shares held by public shareholders, 7,625,000 issued and outstanding Class F Ordinary Shares held by the Sponsor and the Company’s independent directors and no issued and outstanding Class B Ordinary Shares. The Company’s warrants do not have voting rights.

The Class F Ordinary Shares are not entitled to redemption rights and will be excluded from the pro rata calculation used to determine the per-share redemption price. As of the date of the accompanying proxy statement, the Sponsor and the Company’s independent directors hold all of the Class F Ordinary Shares or approximately 35.7% of the issued and outstanding Ordinary Shares. The Company’s officers do not own any Ordinary Shares directly. As a result, in addition to the Class F Ordinary Shares, (i) approval

TABLE OF CONTENTS

of the Articles Amendment Proposal will require the affirmative vote of at least 6,608,242 Public Shares (or approximately 48.1% of the Public Shares) if all Public Shares are represented at the Shareholder Meeting and cast votes, and no Public Shares if only such shares as are required to establish a quorum are represented at the Shareholder Meeting and cast votes, (ii) approval of the IMTA Amendment Proposal will require the affirmative vote of at least 6,252,411 Public Shares (or approximately 45.6% of the Public Shares) and (iii) approval of the Adjournment Proposal will require the affirmative vote of at least 3,049,932 Public Shares (or approximately 22.2% of the Public Shares) if all Public Shares are represented at the Shareholder Meeting and cast votes, and no Public Shares if only such shares as are required to establish a quorum are represented at the Shareholder Meeting and cast votes.

The accompanying proxy statement contains important information about the Shareholder Meeting, the Proposals. Whether or not you plan to attend the Shareholder Meeting, the Company urges you to read this material carefully and vote your shares.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements contained in this proxy statement constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. Forward-looking statements reflect the current views of the Company with respect to, among other things, the Company’s capital resources and results of operations. Likewise, the Company’s financial statements and all of the Company’s statements regarding market conditions and results of operations are forward-looking statements. In some cases, you can identify these forward-looking statements by the use of terminology such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates” or the negative version of these words or other comparable words or phrases.

The forward-looking statements contained in this proxy statement reflect the Company’s current views about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances that may cause its actual results to differ significantly from those expressed in any forward-looking statement. The Company does not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

•

risks associated with the Company’s ability to realize the anticipated benefits of the Settlement Agreement and the Notes, including that the Company may not receive the payments due thereunder on time, in full or at all;

•

the volatility of the market price and liquidity of the Public Shares (as defined below) and other securities of the Company;

•

the fact that the Company’s securities may cease to be listed on a national securities exchange; and

•

the amount and timing of the use of any funds available to the Company from interest income on the Trust Account balance, repayment of the Note, a Trigger Event Payment or otherwise, including relating to potential future distributions.

While forward-looking statements reflect the Company’s good faith beliefs, they are not guarantees of future performance. The Company disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes after the date of this proxy statement, except as required by applicable law. For a further discussion of these and other factors that could cause the Company’s future results, performance or transactions to differ significantly from those expressed in any forward-looking statement, please see the section entitled “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the U.S. Securities and Exchange Commission (the “ SEC ”) on March 28, 2025, as amended by the Company’s Amendment No. 1 to Annual Report on Form 10K/A, as filed with the SEC on April 2, 2025, any subsequently filed Quarterly Reports on Form 10-Q and in other reports the Company files with the SEC.

Why am I receiving this proxy statement?

This proxy statement and the enclosed proxy card are being sent to you in connection with the solicitation of proxies by the Board for use at the Shareholder Meeting, or at any adjournments thereof. This proxy statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Shareholder Meeting.

The Company is a blank check company incorporated as a Cayman Islands exempted company and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganisation or similar business combination involving the Company, with one or more businesses or entities (an “ initial business combination ”).

Following the closing of the IPO, $308,050,000 from the net proceeds of the sale of the units offered in the IPO (the “ Units ”) in the Company’s initial public offering (the “ IPO ”), the sale of private placement warrants (the “ Private Placement Warrants ”) to direct and indirect owners of Nabors Energy Transition Sponsor II LLC, a Cayman Islands limited liability company (the “ Sponsor ”), and loans from the direct and indirect owners of the Sponsor in exchange for unsecured promissory notes (the “ Overfunding Loans ”) was placed in the trust account established in connection with the IPO (the “ Trust Account ”).

Like most blank check companies, the Company’s Second Amended and Restated Memorandum and Articles of Association (the “ Second A&R Memorandum and Articles of Association ”) provides for the return of the funds held in trust to the holders of Class A ordinary shares, par value $0.0001 per share (the “ Class A Ordinary Shares ”), issued as part of the Units (the “ Public Shares ”) if there is no qualifying initial business combination(s) consummated on or before July 18, 2025, subject to twelve one-month extensions (or up to July 18, 2026), provided that the Sponsor (or its affiliates or designees) deposits additional funds of $250,000 for each one-month extension (each such extension, a “ Monthly Extension Period ”) into the Trust Account in exchange for a non-interest bearing, unsecured promissory note (each such payment, a “ Monthly Extension Payment ”). The Board has previously elected to effectuate four one-month extensions to extend the date by which the Company has to consummate an initial business combination (the “ Termination Date ”) from July 18, 2025 to November 18, 2025.

On February 11, 2025, the Company and Liffey Merger Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company (“ Merger Sub ”), entered into the Business Combination Agreement and Plan of Reorganization (the “ Business Combination Agreement ” and the transaction contemplated therein, the “ e2 Business Combination ”) with e2Companies LLC, a Florida limited liability company (“ e2 ”).

owed to a priority creditor, (ii) the parties agreed to dismiss with prejudice the previously disclosed action styled Nabors Energy Transition Corp. II, et al. v. e2Companies LLC , 2025-0810-BWD (the “ Action ”) and release the parties from various known and unknown claims, subject to certain carve-outs, effective upon the Settlement Date, and (iii) the Business Combination Agreement and all ancillary agreements entered into in connection therewith were deemed terminated by mutual agreement upon the Settlement Date. Prior to the maturity date of the Second Note, upon the occurrence of a Payment Event (as defined below), (i) that is a change of control (other than a change of control of a Covered Entity (as defined below) formed to effect a sale of inventory that does not result in the transfer of more than 60% of the book value of e2’s consolidated total assets), each Note shall become due and payable in full and (ii) that is not a change of control, a minimum of 50% of the net proceeds from any Payment Event directly received by a Covered Entity or its shareholders, successors or assigns in excess of a cumulative threshold of $17.5 million of the net proceeds from all Payment Events received by a Covered Entity or its shareholders, successors or assigns, shall be used to repay, in whole or in part, first the Second Note and then the First Note (but not more than the amount of the then-current principal plus accrued interest with respect to each Note) no later than three (3) business days following consummation of such Payment Event. Further, a minimum of 10% of the net proceeds from up to $22 million of debt or equity financings by a Covered Entity consummated on or prior to March 31, 2026, the sole use of the proceeds of which (after expenses attributable to the financing) is the repayment or refinancing of indebtedness outstanding as of the Settlement Date, shall be used to repay, in whole or in part, first the Second Note and then the First Note (but not more than the amount of the then-current principal plus accrued interest with respect to each Note) no later than three (3) business days following consummation of such financing. A “ Payment Event ” means the occurrence of one or more of the following events within three years from the Settlement Date: (i) a debt or equity financing by a Covered Entity (including an initial public offering), excluding a financing where the sole use of net proceeds (after expenses attributable to the financing) is (x) to finance the acquisition of equipment to be added to inventory or (y) to fund all or a portion of the payment of the Notes; (ii) a sale or exchange by a Covered Entity or its shareholders of any of its interest in a Covered Entity, whether directly or indirectly; (iii) a sale or exchange of assets constituting 20% or more of the book value of e2’s consolidated total assets as of the end of the most recently completed calendar quarter by a Covered Entity, other than the sale of inventory in the ordinary course of business; or (iv) a change of control of a Covered Entity. If the Company enters into a definitive agreement with respect to an initial business combination prior to the maturity date of the Second Note and such initial business combination is consummated, the remaining then-current principal amount of the Second Note shall be cancelled and no further interest shall continue to accrue. However, all interest accrued and unpaid with respect to the Second Note prior to but not including the date of the consummation of any initial business combination shall be due and payable from e2 in connection therewith. Any amount paid by e2 to the Company under the Second Note prior to the consummation of any initial business combination, shall not be required to be returned to e2.

TABLE OF CONTENTS

The Company believes that it is in the best interests of the Company and its shareholders to provide for the continued existence of the Company even without the Monthly Extension Payments, and, assuming all of the Proposals pass, the Board currently anticipates maintaining the Company’s existence until all payments are made under the Settlement Agreement and the Notes. On October 23, 2025, the most recent practicable date prior to the date of this proxy statement, the redemption price per share was approximately $11.31, based on the aggregate amount on deposit in the Trust Account of approximately $155.3 million as of October 23, 2025 (including interest not previously released to the Company to pay taxes), divided by the total number of then outstanding Public Shares. Any shareholder that does not redeem in connection with the Articles Amendment is expected to receive (i) a pro rata portion of the funds available in the Trust Account at the time the Company winds up, which is expected to constitute, for each Public Share, (x) the proceeds of the Trust Account, less (y) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment, and (ii) a pro rata portion (allocated among the Public Shares not redeemed and the Class F Ordinary Shares) of any payments under the Settlement Agreement and the Notes, net of fees and expenses paid or to be paid by or on behalf of the Company. We expect the Board will declare pro rata distributions of such net proceeds of payments under the Settlement Agreement and the Notes from time to time following receipt thereof, but there can be no assurances that such payments will be received in full or at all or as to the amount of fees and expenses of the Company, and any such distribution will be at the discretion of the Board.

Will the settlement proceeds be placed into the Trust Account?

No. Any proceeds of the settlement will be held outside of the Trust Account. If the Articles Amendment Proposal and the IMTA Amendment Proposal are approved, Public Shareholders who do not redeem are expected to receive a pro rata portion (allocated among non-redeeming Class A Ordinary Shares and Class F Ordinary Shares) of any payments under the Settlement Agreement and the Notes, net of fees and expenses, including loan repayments. In addition, Public Shareholders who do not redeem are expected to receive a pro rata portion of the funds available in the Trust Account at the time the Company liquidates and dissolves, which is expected to be (x) the proceeds of the Trust Account, less (y) up to $0.50 per Public Share not redeemed and up to 100% of the interest accrued from the date of the IMTA Amendment.

What fees and expenses does the Company have? How will those be paid?

As of the date of this proxy statement, the Company has incurred approximately $10 million of fees and expenses. In addition, the Sponsor and its affiliates have made approximately $4.1 million of loans to the Company, which loans were funded into the Trust Account. The Company may incur additional expenses in the future in connection with maintaining its corporate existence, enforcing its rights under the Settlement Agreement and the Notes or otherwise.

The fees and expenses, including the loan repayments, are expected to be paid from the proceeds of the Settlement Agreement and the Notes.

If the IMTA Amendment Proposal passes, with respect to Public Shares that are not redeemed, the Company will be able to withdraw from the Trust Account up to $0.50 per share and up to 100% of the interest that accrues in the future to pay fees and expenses incurred by or on behalf of the Company since its formation.

How long do you expect the Company to continue to exist?

The Board believes it is in the best interests of the Company and its shareholders to provide for the continued existence of the Company until all payments are made under the Settlement Agreement and the Notes. The Board has been informed that neither Sponsor nor its affiliates intend to fund any further Monthly Extension Payments. We are seeking an amendment to our organizational documents to allow for an indefinite extension without the need to make Monthly Extension Payments. The Board believes it is in the best interests of the Company and its shareholders to provide for the continued existence of the Company even without the Monthly Extension Payments, and the Board currently

TABLE OF CONTENTS

anticipates maintaining the Company’s existence until all payments are made under the Settlement Agreement and the Notes. We are also seeking an amendment to the Trust Agreement to allow us to use a portion of the interest on the funds held in the Trust Account after any applicable redemptions to help pay fees and expenses.

What are the specific proposals on which I am being asked to vote at the Shareholder Meeting?

The Company’s shareholders are being asked to consider and vote on the following proposals:

Proposal No. 1 — Articles Amendment Proposal — To consider and vote upon a proposal to approve by special resolution, with effect from such date as determined by the Board in its sole discretion, an amendment to the Second A&R Memorandum and Articles of Association to (i) delete Article 49 (Business Combination), other than Article 49.7, in its entirety and (ii) extend the date by which the Company has to consummate an initial business combination indefinitely (the “ Indefinite Extension ” and such proposal, the “ Articles Amendment Proposal ”).

The text of the special resolution and a copy of the form of the proposed Amendment to the Second Amended and Restated Memorandum and Articles of Association are set forth in Annex A to this proxy statement, which we refer to as the “ Articles Amendment ”.

Proposal No. 2 — IMTA Amendment Proposal — To consider and vote upon a proposal to approve an amendment and restatement of the Amended and Restated Investment Management Trust Agreement, dated as of July 17, 2025 (the “ Trust Agreement ”), by and between the Company and Continental Stock Transfer & Trust Company, as trustee, to permit the Company (i) to withdraw from the interest earned on the Trust Account established in connection with the IPO (x) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (y) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation and (ii) to reflect the Indefinite Extension (such proposal, the “ IMTA Amendment Proposal ”).

A copy of the form of the proposed Second Amended and Restated Investment Management Trust Agreement, which we refer to as the “ IMTA Amendment ,” is set forth in Annex B to this proxy statement.

Proposal No. 3 — Adjournment Proposal — To consider and vote upon a proposal to approve by ordinary resolution the adjournment of the Shareholder Meeting to a later date or dates or indefinitely, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Shareholder Meeting, there are insufficient Class A Ordinary Shares, Class B ordinary shares, par value $0.0001 per share (the “ Class B Ordinary Shares ”), and Class F ordinary shares, par value $0.0001 per share (the “ Class F Ordinary Shares ” and, collectively with the Class A Ordinary Shares and the Class B Ordinary Shares, the “ Ordinary Shares ”), in the share capital of the Company represented (either in person, virtually or by proxy) at the time of the Shareholder Meeting to approve the Articles Amendment Proposal or the IMTA Amendment Proposal or if the Board otherwise determined before the Shareholder Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposal or the IMTA Amendment Proposal (such proposal, the “ Adjournment Proposal ” and, collectively with the Articles Amendment Proposal and the IMTA Amendment Proposal, the “ Proposals ”), in which case the Adjournment Proposal will be the only proposal presented at the Shareholder Meeting.

The text of the ordinary resolution is as follows:

TABLE OF CONTENTS

(either in person, virtually or by proxy) at the time of the Shareholder Meeting to approve the Articles Amendment Proposal or the IMTA Amendment Proposal, or if the Board otherwise determined before the Shareholder Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposal or the IMTA Amendment Proposal.”

For more information, please see “ The Articles Amendment Proposal ”, “ The IMTA Amendment Proposal ” and “ The Adjournment Proposal .”

After careful consideration, the Board has unanimously determined that the Proposals are in the best interests of the Company and its shareholders and unanimously recommends that you vote “FOR” or give instruction to vote “FOR” each of these proposals.

The existence of financial and personal interests of our directors and officers may result in conflicts of interest, including a conflict between what may be in the best interests of the Company and its shareholders and what may be best for a director’s personal interests when determining to recommend that shareholders vote for the proposals. See the sections titled “ The Articles Amendment Proposal — Interests of the Sponsor and the Company’s Directors and Officers ” and “ Beneficial Ownership of Securities ” for a further discussion of these considerations.

THE VOTE OF SHAREHOLDERS IS IMPORTANT. SHAREHOLDERS ARE URGED TO SUBMIT THEIR PROXIES AS SOON AS POSSIBLE AFTER CAREFULLY REVIEWING THIS PROXY STATEMENT.

Am I being asked to vote on a proposal to appoint directors?

No. Holders of Public Shares are not being asked to vote on the appointment of directors at this time.

Are the proposals conditioned on one another?

None of the Articles Amendment Proposal or the IMTA Amendment Proposal are conditioned on the approval of any of the other Proposals, and no other Proposal is conditioned on the approval of the Articles Amendment Proposal or the IMTA Amendment Proposal. If either the Articles Amendment Proposal or the IMTA Amendment Proposal is not approved, the Company may in the future ask shareholders to approve proposals similar to the Proposals. The Sponsor has informed the Board that it does not intend to fund, nor does it intend to cause any of its affiliates or designees to fund, any further Monthly Extension Payments (as defined below). If any of the Proposals are not approved and future Monthly Extension Payments are not made, the Company may be wound up in accordance with the Second A&R Memorandum and Articles of Association (as may be amended).

As contemplated by the Second A&R Memorandum and Articles of Association, the holders of Public Shares may elect to redeem all or a portion of their Public Shares (the “ Redemptions ”) in exchange for their pro rata portion of the funds held in the Trust Account as of two business days prior to the Shareholder Meeting, if the Articles Amendment is implemented, regardless of whether or how such public shareholders vote in regard to such proposal. If the Articles Amendment is implemented and one or more the Company’s shareholders elect to redeem their Public Shares pursuant to such redemption right, the Company will remove from the Trust Account and deliver to the holders of such redeemed Public Shares an amount equal to the pro rata portion of funds available in the Trust Account with respect to such redeemed Public Shares, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes, if any, and retain the remainder of the funds in the Trust Account. The Company may (and intends to) accept Redemptions in the event the Articles Amendment Proposal is not approved and the Articles Amendment is not implemented.

Why is the Company proposing the Proposals?

TABLE OF CONTENTS

Proposal is to allow the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation.

If the Adjournment Proposal is not approved, the Board may not be able to adjourn the Shareholder Meeting to a later date or dates in the event there are insufficient votes for, or otherwise in connection with, the approval of the Articles Amendment Proposal and the IMTA Amendment Proposal.

The Company reserves the right at any time to cancel the Shareholder Meeting (by means of holding and thereafter adjourning the Shareholder Meeting sine die or indefinitely) and to not submit the Articles Amendment Proposal or the IMTA Amendment Proposal to its shareholders. In the event the Shareholder Meeting is cancelled (by means of holding and thereafter adjourning the Shareholder Meeting sine die or indefinitely), and an initial business combination is not consummated on or before the Termination Date, and such date is not extended, the Company will wind up in accordance with the Second A&R Memorandum and Articles of Association.

What constitutes a quorum?

A quorum of our shareholders is necessary to hold a valid meeting. The presence, in person, virtually or by proxy, of shareholders holding one-third (1/3) in voting power of the Ordinary Shares entitled to vote at the Shareholder Meeting constitutes a quorum at the Shareholder Meeting. Abstentions will be considered present for the purposes of establishing a quorum but will not count as votes cast and therefore will have the same effect as a vote “AGAINST” the IMTA Amendment Proposal and will have no effect on the approval of the Articles Amendment Proposal and the Adjournment Proposal. The Sponsor and the Company’s independent directors, who collectively beneficially own approximately 35.7% of the issued and outstanding Ordinary Shares as of the Record Date, will count towards this quorum. As a result, as of the Record Date, no additional Ordinary Shares held by public shareholders would be required to be present at the Shareholder Meeting to achieve a quorum. Because the Proposals are “non-routine” matters, banks, brokers and other nominees will not have authority to vote on any proposals unless instructed. Therefore, such broker non-votes will not count towards quorum at the Shareholder Meeting. In the absence of a quorum, the chairman of the Shareholder Meeting has the power to adjourn the Shareholder Meeting. You can also attend the Shareholder Meeting and vote in person or online. Even if you have previously voted by submitting a proxy pursuant to any of the methods noted above, you may withdraw your proxy and vote in person or online.

What vote is required to approve the proposals presented at the Shareholder Meeting?

How will the Sponsor and the Company’s directors and officers vote?

The Sponsor and the Company’s directors and officers have not provided a final decision on how they intend to vote any Ordinary Shares over which they have voting control.

On the Record Date, the Sponsor and the Company’s independent directors beneficially owned and were entitled to vote an aggregate of 7,625,000 Class F Ordinary Shares, representing approximately 35.7% of the Company’s issued and outstanding Ordinary Shares. The Class F Ordinary Shares are not entitled to redemption rights. The Company’s officers do not own any Ordinary Shares directly.

TABLE OF CONTENTS

Who is the Company’s Sponsor?

The Company’s sponsor, Nabors Energy Transition Sponsor II LLC, a Cayman Islands limited liability company, is managed by Nabors Lux 2 S.a.r.l., a private limited liability company (société à responsabilité limitée) (“ Nabors Lux ”) incorporated in the Grand Duchy of Luxembourg. The Sponsor is owned by (i) Nabors Lux, a subsidiary of Nabors Industries Ltd., a Bermuda company publicly traded on the New York Stock Exchange (“ Nabors ”; NYSE: NBR), and (ii) Greens Road Energy II LLC, a Cayman Islands limited liability company controlled by Anthony G. Petrello, a U.S. citizen (“ Greens Road ”), the Company’s President, Chief Executive Officer, Secretary and Chairman and Chairman, President and Chief Executive Officer of Nabors. Nabors owns and operates one of the world’s largest land-based drilling rig fleets and provides offshore platform rigs and related services in the United States and several international markets.

Why should I vote “FOR” the Articles Amendment Proposal and the IMTA Amendment Proposal?

The Company is proposing the Articles Amendment Proposal to allow the Company to remain in existence indefinitely to receive the payments under the Settlement Agreement and Notes and to remove the obligations under the Second A&R Memorandum and Articles of Association for the Sponsor (or its affiliates or designees) to make the Monthly Extension Payments. The Company is proposing the IMTA Amendment Proposal to allow the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation.

Without the Articles Amendment or the IMTA Amendment, the Company may not be able to remain in existence to enforce its rights under the Notes and to receive the proceeds under the Settlement Agreement and the Notes and would be forced to initiate the process of winding up on the Termination Date, subject to any Monthly Extension Periods. The Sponsor has informed the Board that it does not intend to fund, nor does it intend to cause any of its affiliates or designees to fund, any further Monthly Extension Payments. The Board believes it is in the best interests of the Company and its shareholders to provide for the continued existence of the Company even without the Monthly Extension Payments, and the Board currently anticipates maintaining the Company’s existence until all payments are made under the Settlement Agreement and the Notes.

What if I do not want to vote “FOR” the Proposals?

If you do not want any of the Proposals to be approved, you may “ABSTAIN,” not vote or vote “AGAINST” such proposal.

If you attend the Shareholder Meeting in person, virtually or by proxy, you may vote “AGAINST” any of the Proposals, and your Ordinary Shares will be counted for the purposes of determining whether the Proposals are approved.

However, if you fail to attend the Shareholder Meeting in person, virtually or by proxy, or if you do attend the Shareholder Meeting in person, virtually or by proxy but you “ABSTAIN” or otherwise fail to vote at the Shareholder Meeting, your Ordinary Shares will not be counted for the purposes of determining whether the Articles Amendment Proposal and the Adjournment Proposal are approved, and your Ordinary Shares which are not voted at the Shareholder Meeting will have no effect on the outcome of such vote. If you “ABSTAIN” or otherwise fail to vote at the Shareholder Meeting, this will have the same effect as a vote “AGAINST” the IMTA Amendment Proposal.

Will you seek any further extensions to extend the Termination Date?

If the Articles Amendment Proposal is approved, the Company’s existence will be indefinite and not subject to a termination date. The Company reserves the right at any time to cancel the Shareholder Meeting (by means of holding and thereafter adjourning the Shareholder Meeting sine die or indefinitely) and to not submit the Articles Amendment Proposal or the IMTA Amendment Proposal to its shareholders.

TABLE OF CONTENTS

What happens if the Articles Amendment Proposal is not approved?

If the Articles Amendment Proposal is not approved, the Company may in the future ask shareholders to approve proposals similar to the Proposals. The Sponsor has informed the Board that it does not intend to fund, nor does it intend to cause any of its affiliates or designees to fund, any further Monthly Extension Payments. If any of the Proposals are not approved and future Monthly Extension Payments are not made, the Company may be wound up in accordance with the Second A&R Memorandum and Articles of Association: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account not previously released to the Company to pay its taxes (net of any taxes payable by the Company and less up to $100,000 of interest that may be released to the Company to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Board, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. In such an event, the Public Shares will have been redeemed, and will not be entitled to participate in any distribution of proceeds of payments under the Settlement Agreement or the Notes. There will be no distribution from the Trust Account with respect to the Company’s warrants, which will expire worthless in the event of our winding up.

If the Articles Amendment Proposal and the IMTA Amendment Proposal are approved, what happens next?

If the Articles Amendment Proposal and the IMTA Amendment Proposal are approved, the Company will file the Articles Amendment with the Registrar of Companies in the Cayman Islands. Holders of Public Shares remaining after the Redemptions will not have another opportunity to redeem their Public Shares for their pro rata portion of the funds available in the Trust Account. The Company does not intend to pursue an initial business combination or the e2 Business Combination at this time. Any shareholder that does not redeem its Public Shares in connection herewith is expected to receive (i) a pro rata portion of the funds available in the Trust Account at the time the Company winds up, which is expected to constitute, for each Public Share, (x) the proceeds of the Trust Account, less (y) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment, and (ii) a pro rata portion (allocated among the Public Shares not redeemed and the Class F Ordinary Shares) of any payments under the Settlement Agreement and the Notes, net of fees and expenses paid or to be paid by or on behalf of the Company. We expect the Board will declare pro rata distributions of such net proceeds of payments under the Settlement Agreement and the Notes from time to time following receipt thereof, but there can be no assurances that such payments will be received in full or at all or as to the amount of fees and expenses of the Company, and any such distribution will be at the discretion of the Board. Up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment may be withdrawn from the interest earned on the Trust Account to pay fees and expenses incurred by or on behalf of the Company since its formation, including those incurred in connection with the Action, and the remainder of the funds will be held until the time the Company liquidates and dissolves as and when determined by the Board, at which time the remaining funds in the Trust Account will be used to redeem the holders of Public Shares remaining after the Redemption in connection with the Shareholder Meeting. As of the date of this proxy statement, the Company has (i) approximately $10.0 million of incurred fees and expenses and (ii) approximately $4.1 million in Overfunding Loans and Monthly Extension Payments. The Company expects that following the Redemptions it will not meet the listing standards of The Nasdaq Stock Market LLC (“ Nasdaq ”) and, accordingly, expects to be delisted from Nasdaq. The Company will remain in existence indefinitely or until such time as the Board determines that the Company liquidate and dissolve.

TABLE OF CONTENTS

If I vote for or against any of the Proposals, do I need to request that my shares be redeemed?

Yes. Whether you vote “for” or “against” any of the Proposals, or do not vote at all, you will need to submit a redemption request for your shares if you choose to redeem.

Am I being asked to vote on an initial business combination at this Shareholder Meeting?

No. You are not being asked to vote on an initial business combination at this time. The Company does not intend to pursue an initial business combination or the e2 Business Combination at this time.

Does the Company plan to look for another business combination target or will it wind up?

We do not intend to pursue another business combination at this time. If the Company were to enter into a definitive agreement for another business combination prior to any Trigger Event Payment, and that business combination is ultimately consummated, the Company will not be entitled to receive any Trigger Event Payment. Additionally, if the Company were to enter into a definitive agreement for another business combination prior to the October 2028 payment of the Second Note, the remaining then-current principal amount of the Second Note will be cancelled and no further interest will accrue. The Board believes it is in the best interests of shareholders that Company maximize its recovery under the Settlement Agreement and the Notes rather than pursue an alternative business combination.

Will the Company continue to be listed?

We expect that following the redemptions, the Company will not meet the Nasdaq listing standards and expects that its Class A Ordinary Shares, Units and warrants will be delisted from Nasdaq.

Will how I vote affect my ability to exercise redemption rights?

No. You may exercise your redemption rights whether or not you are a holder of Public Shares on the Record Date (so long as you are a holder at the time of exercise), or whether you are a holder and vote your Public Shares on the Articles Amendment Proposal (for or against) or any other proposal described in this proxy statement. As a result, the Articles Amendment and the IMTA Amendment can each be approved by shareholders who will redeem their Public Shares and no longer remain shareholders, leaving shareholders who choose not to redeem their Public Shares holding shares in a company with a potentially less liquid trading market, fewer shareholders, potentially less cash and the potential inability to meet the listing standards of Nasdaq.

May I change my vote after I have mailed my signed proxy card?

Yes. Shareholders may send a later-dated, signed proxy card to Nabors Energy Transition Corp. II at 515 West Greens Road, Suite 1200, Houston, TX 77067, so that it is received by the Company prior to the vote at the Shareholder Meeting (which is scheduled to take place on November 14, 2025) or attend the Shareholder Meeting and vote electronically in person or virtually. Shareholders also may revoke their proxy by sending a notice of revocation to the Company’s Chief Executive Officer, which must be received by the Company’s Chief Executive Officer prior to the vote at the Shareholder Meeting. However, if your shares are held in “street name” by your broker, bank or another nominee, you must contact your broker, bank or other nominee to change your vote.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Shareholder Meeting, who will separately count “FOR” and “AGAINST” votes and abstentions. The approval of the Articles Amendment Proposal requires a special resolution under Cayman Islands law, which is a resolution passed by a majority of at least two-thirds (2/3) of such shareholders of the Company as, being entitled to do so, vote in person or by proxy at the Shareholder Meeting. Pursuant to the Trust Agreement, the approval of the IMTA Amendment Proposal requires the affirmative vote of the holders of at least sixty-five percent (65%) of the issued and outstanding Ordinary Shares, voting together as a single class. The approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands

TABLE OF CONTENTS

law, which is a resolution passed by a simple majority of the shareholders of the Company as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Shareholder Meeting.

Shareholders who attend the Shareholder Meeting, either in person, virtually or by proxy, will be counted (and the number of Ordinary Shares held by such shareholders will be counted) for the purposes of determining whether a quorum is present at the Shareholder Meeting. The presence, in person, virtually or by proxy, of shareholders holding one-third (1/3) in voting power of the Ordinary Shares entitled to vote at the Shareholder Meeting constitutes a quorum at the Shareholder Meeting.

With respect to the IMTA Amendment Proposal, abstentions will have the same effect as a vote “AGAINST” the proposal. As this proposal is not a “routine” matter, brokers will not be permitted to exercise discretionary voting on this proposal.

With respect to the Articles Amendment Proposal and the Adjournment Proposal, abstentions will have no effect on the approval of such proposals. As these proposals are not “routine” matters, brokers will not be permitted to exercise discretionary voting on these proposals.

If my shares are held in “street name,” will my broker, bank or nominee automatically vote my shares for me?

If your shares are held in “street name” in a stock brokerage account or by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in “street name” by returning a proxy card directly to the Company or by voting online at the Shareholder Meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee.

Under the applicable rules, brokers who hold shares in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not permitted to exercise their voting discretion with respect to the approval of matters that are determined to be “non-routine” without specific instructions from the beneficial owner. The Articles Amendment Proposal, the IMTA Amendment Proposal and the Adjournment Proposal are “non-routine” matters and therefore, brokers are not permitted to exercise their voting discretion with respect to these proposals.

If you are a shareholder holding your shares in “street name” and you do not instruct your broker, bank or other nominee on how to vote your shares, your broker, bank or other nominee will not vote your shares on the Proposals. Accordingly, your bank, broker, or other nominee can vote your shares on the Proposals at the Shareholder Meeting only if you provide instructions on how to vote. You should instruct your broker to vote your shares as soon as possible in accordance with directions you provide.

Does the Board recommend voting “FOR” the approval of the Proposals?

Yes. After careful consideration of the terms and conditions of each of the Proposals, the Board has determined that each of the Proposals is in the best interests of the Company and its shareholders. The Board unanimously recommends that the Company’s shareholders vote “FOR” each of the Proposals.

What interests do the Company’s directors and officers have in the approval of the Proposals?

The Company’s directors and officers have interests in the Proposals that may be different from, or in addition to, your interests as a shareholder. These interests include, among others, ownership, directly or indirectly through the Sponsor, of Ordinary Shares and Private Placement Warrants. See the section entitled “ The Articles Amendment Proposal — Interests of the Sponsor and the Company’s Directors and Officers ” in this proxy statement.

Do I have appraisal rights or dissenters’ rights if I object to the Articles Amendment Proposal or the IMTA Amendment Proposal?

Neither Cayman Islands law nor the Second A&R Memorandum and Articles of Association provide

TABLE OF CONTENTS

for dissenters’ rights or appraisal rights to the Company’s shareholders in connection with the Articles Amendment Proposal or the IMTA Amendment Proposal. However, you may elect to have your shares redeemed in connection with the adoption of the Articles Amendment Proposal as described under “ How do I exercise my redemption rights ?” below.

If I am a holder of Public Warrants (as defined below), can I exercise redemption rights with respect to my Public Warrants?

No. The holders of public warrants issued in connection with the IPO (with a whole warrant representing the right to acquire one Class A Ordinary Share at an exercise price of $11.50 per share) (the “ Public Warrants ”) have no redemption rights with respect to such Public Warrants.

Will warrantholders receive any portion of the settlement?

No. The warrants are not exercisable until 30 days after the completion of an initial business combination. We do not intend to pursue another business combination at this time, so we do not expect the warrants will ever be exercisable. Warrantholders will not be entitled to receive any portion of any payments under the Settlement Agreement or the Notes, and there will be no distribution from the Trust Account with respect to the warrants.

What do I need to do now?

You are urged to read carefully and consider the information contained in this proxy statement and to consider how the Proposals will affect you as a shareholder. You should then vote as soon as possible in accordance with the instructions provided in this proxy statement and on the enclosed proxy card or, if you hold your shares through a brokerage firm, bank or other nominee, on the voting instruction form provided by the broker, bank or nominee.

How do I exercise my redemption rights?

If you are a holder of Public Shares and wish to exercise your right to redeem your Public Shares, you must:

(a) hold Public Shares or (b) hold Public Shares through Units and elect to separate your Units into the underlying Public Shares and Public Warrants prior to exercising your redemption rights with respect to the Public Shares;

II.

prior to 4:00 p.m., Central Time, on November 12, 2025 (two business days prior to the initially scheduled date of the Shareholder Meeting) (the “ Redemption Deadline ”) (a) submit a written request to the Transfer Agent that the Company redeem all or a portion of your Public Shares for cash and (b) identify yourself as the beneficial holder of the Public Shares and provide your legal name, phone number and address; and

III.

deliver your Public Shares to the Transfer Agent, physically or electronically through the Depository Trust Company (“ DTC ”).

The address of the Transfer Agent is listed under the question “ Who can help answer my questions? ” below.

Holders of Units must elect to separate the underlying Public Shares and Public Warrants prior to exercising redemption rights with respect to the Public Shares. If holders hold their Units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the Units into the underlying Public Shares and Public Warrants, or if a holder holds Units registered in its own name, the holder must contact the Transfer Agent directly and instruct it to do so.

In connection with the Proposals and contingent upon the effectiveness of the implementation of the Articles Amendment, any holder of Public Shares will be entitled to request that their Public Shares be redeemed for a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the Shareholder Meeting, including interest

TABLE OF CONTENTS

earned on the funds held in the Trust Account and not previously released to the Company to pay taxes, divided by the number of then-outstanding Public Shares. As of October 23, 2025, the most recent practicable date prior to the date of this proxy statement, this would have amounted to approximately $11.31 per Public Share.

However, the proceeds deposited in the Trust Account could become subject to the claims of our creditors, if any, which could have priority over the claims of our public shareholders. Therefore, the per share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. We anticipate that the funds to be distributed to public shareholders electing to redeem their Public Shares will be distributed promptly after the Shareholder Meeting.

Any request for Redemption, once made by a holder of Public Shares, may be withdrawn at any time until the Redemption Deadline, and thereafter, with the approval of the Board. If you deliver your shares for Redemption to the Transfer Agent and later decide prior to the Redemption Deadline not to elect Redemption, you may request that the Company instruct the Transfer Agent to return the shares (physically or electronically). You may make such request by contacting the Transfer Agent at the phone number or address listed at the end of this section. We will be required to honor such request only if made prior to the deadline for exercising redemption requests.

No request for Redemption will be honored unless the holder’s shares have been delivered (either physically or electronically) to the Transfer Agent by 4:00 p.m., Central Time, on November 12, 2025 (two business days prior to the initially scheduled date of the Shareholder Meeting).

If a holder of Public Shares properly makes a request for Redemption and the Public Shares are delivered as described above, then, the Company will redeem Public Shares for a pro rata portion of funds deposited in the Trust Account, calculated as of two business days prior to the Shareholder Meeting. If you are a holder of Public Shares and you exercise your redemption rights, it will not result in the loss of any Public Warrants that you may hold.

If the Shareholder Meeting is not held for any reason, then holders of Public Shares shall not have the right to redeem their Public Shares at this time.

What are the U.S. federal income tax consequences of a redemption of Public Shares?

The receipt of cash by a U.S. Holder (as defined below under the section entitled “ Material U.S. Federal Income Tax Considerations for Shareholders with Respect to a Redemption of Public Shares ”) of Public Shares in redemption of its Public Shares will be a taxable event for U.S. federal income tax purposes and may be a taxable event for U.S. federal income tax purposes in the case of holders who are not U.S. Holders. U.S. Holders should read the discussion below under the section entitled “ Material U.S. Federal Income Tax Considerations for Shareholders with Respect to a Redemption of Public Shares ” for additional information. The tax consequences to each holder of Public Shares will depend on such holder’s own situation. Each holder of Public Shares should consult its own tax advisors as to the specific tax consequences to it of a redemption of its Public Shares, including as a result of the exercise of its redemption rights or in connection with the winding up of the Company, including the applicability and effect of U.S. federal, state and local and non-U.S. income and other tax laws in light of such holder’s particular circumstances.

What should I do if I receive more than one set of voting materials for the Shareholder Meeting?

You may receive more than one set of voting materials for the Shareholder Meeting, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast your vote with respect to all of your shares.

Who will solicit and pay the cost of soliciting proxies for the Shareholder Meeting?

The Company will pay the cost of soliciting proxies for the Shareholder Meeting. The Company has

TABLE OF CONTENTS

engaged Sodali & Co. (“ Sodali ”) to assist in the solicitation of proxies for the Shareholder Meeting. The Company will also reimburse banks, brokers and other custodians, nominees and fiduciaries representing beneficial owners of Public Shares for their expenses in forwarding soliciting materials to beneficial owners of Public Shares and in obtaining voting instructions from those owners. The directors, officers and employees of the Company may also solicit proxies by telephone, by facsimile, by mail or on the Internet. They will not be paid any additional amounts for soliciting proxies.

RISK FACTORS

In addition to the below risk factors, you should consider carefully all of the risks described in our Annual Report on Form 10-K filed with the SEC on March 28, 2025, as amended by the Company’s Amendment No. 1 to Annual Report on Form 10K/A, as filed with the SEC on April 2, 2025, any subsequent Quarterly Report on Form 10-Q filed with the SEC and in the other reports we file with the SEC before making a decision to invest in our securities. The risks and uncertainties described in the aforementioned filings and below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, financial condition and operating results or result in our liquidation.

If the Proposals (other than the Adjournment Proposal) are approved and the Articles Amendment is made effective and you do not redeem your Public Shares in connection with the Shareholder Meeting, you may not have the opportunity to sell your Public Shares in the future.

If the Proposals (other than the Adjournment Proposal) are approved by the requisite vote of shareholders and the Articles Amendment is made effective, holders of Public Shares remaining after the Redemptions will not have another opportunity to redeem their Public Shares for their pro rata portion of the funds available in the Trust Account. Following the Redemptions, the Company does not intend to pursue an initial business combination or the e2 Business Combination at this time. Any shareholder that does not redeem its Public Shares in connection herewith is expected to receive (i) a pro rata portion of the funds available in the Trust Account at the time the Company winds up, which is expected to constitute, for each Public Share, (x) the proceeds of the Trust Account, less (y) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment, and (ii) a pro rata portion (allocated among the Public Shares not redeemed and the Class F Ordinary Shares) of any payments under the Settlement Agreement and the Notes, net of fees and expenses paid or to be paid by or on behalf of the Company. We expect the Board will declare pro rata distributions of such net proceeds of payments under the Settlement Agreement and the Notes from time to time following receipt thereof, but there can be no assurances that such payments will be received in full or at all or as to the amount of fees and expenses of the Company, and any such distribution will be at the discretion of the Board. Up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment may be withdrawn from the interest earned on the Trust Account to pay fees and expenses incurred by or on behalf of the Company since its formation, including those incurred in connection with the Action, and the remainder of the funds transferred from the Trust Account will be held until the time the Company liquidates and dissolves as and when determined by the Board, at which time the remaining proceeds will be used to redeem the holders of Public Shares remaining after the Redemption in connection with the Shareholder Meeting. As of the date of this proxy statement, the Company has (i) approximately $10.0 million of incurred fees and expenses and (ii) approximately $4.1 million in Overfunding Loans and Monthly Extension Payments. The Company will remain in existence indefinitely or until such time as the Board determines that the Company liquidate and dissolve.

We expect our Class A Ordinary Shares to be delisted from Nasdaq following the Shareholder Meeting, after which it will not be possible for shareholders to publicly trade our shares.

We expect a large number of public shareholders may exercise their redemption rights in connection with the Articles Amendment and, as a result, we will not meet Nasdaq’s continued listing standards and our Class A Ordinary Shares may be delisted from Nasdaq. Following delisting, there will not be a liquid trading market for our Class A Ordinary Shares.

The Company may not receive payment under the Settlement Agreement or the Notes by either maturity date or at all and the Company may not receive payment if it enters into an initial business combination.

Our receipt of the payment of the amounts due under the Settlement Agreement or under the Notes at the applicable maturity date will be dependent upon e2’s ability to pay its obligations under the Settlement Agreement and the Notes on the applicable payment date. If e2 becomes unable to meet its respective financial obligations as they become due, we may not receive any or all of the amount(s) payable under the terms of

TABLE OF CONTENTS

the Settlement Agreement or the Notes. While the Notes will be secured, the security interests will not vest until obligations owed to a priority creditor are paid in full and actions to “perfect” the security interest may not be able to be taken until the security interest vests. Our status as a secured creditor may be impaired by virtue of this delay. Whether as a result of being unsecured or otherwise, in the event of a default under the Notes, we may not be able to (or it may be impractical to) foreclose on the collateral securing the Notes and/or the value of such collateral may be less than the amount owed under the Notes.

If, at the time of a Trigger Event, the Company has entered into a definitive agreement for an initial business combination, but such initial business combination has not yet been consummated, then any Trigger Event Payment shall instead be deposited by e2 into an escrow account. If such definitive agreement for an initial business combination is terminated, the Trigger Event Payment will be released to the Company, and if such initial business combination is consummated, the Trigger Event Payment will be released to e2.

The Notes will be secured by the equity interests of Mission Critical e2 LLC and Mission Critical e2 Limited (“Mission Critical”) (but, in each case, only upon repayment in full of a priority creditor), and such collateral is subject to a variety of risks associated with the Energy Services Agreement by and between Mission Critical and Herbata, some of which are outside of our control.

Herbata Limited, an Irish land development company (“ Herbata ”), is party to that certain Put and Call Option Agreement by and among Herbata, Mission Critical, Moffett Investment Holdings Unlimited Company and the shareholders of Herbata party thereto, dated April 9, 2024, pursuant to which (i) within the period starting on the date on which Herbata receives the final grant of applicable planning permission by the relevant authority for construction, development, and operation of the Herbata Project (the “ Planning Permissions ”) and ending on the six month anniversary of the date of the receipt of such Planning Permissions, Herbata has the option to require e2, through Mission Critical, to purchase the entire issued share capital of Herbata and the data center campus in Kildare County, Ireland on a three-hectare site which will include six two-story data center buildings at Jigginstown, Halverstown, and Newhall, Naas, adjacent to the M7 Business Park (the “ Herbata Project ”) that Herbata is developing (the “ Put Option ”) and (ii) provided that the Put Option is not exercised at the time, until the expiration of the six month anniversary of the date of the receipt of such Planning Permissions, e2 may purchase the entire issued share capital of Herbata and the Herbata Project site, together with all related Planning Permissions.

Additionally, we are subject to other risks, including:

•

Herbata’s financial conditions and creditworthiness;

•

Herbata’s ability to complete its project on projected timeline and within forecasted budget;

•

risks and delays associated with Herbata obtaining requisite permits and approvals; and

•

ability to obtain financing for Herbata’s project on attractive terms or at all.

If we are deemed to be an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”), we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete an initial business combination.

If we are deemed to be an investment company under the Investment Company Act, our activities may be restricted, including,

•

restrictions on the nature of our investments; and

•

restrictions on the issuance of securities, each of which may make it difficult for us to complete an initial business combination.

In addition, we may have imposed upon us burdensome requirements, including:

•

registration as an investment company;

•

adoption of a specific form of corporate structure; and

•

reporting, record keeping, voting, proxy and disclosure requirements and other rules and regulations.

TABLE OF CONTENTS

In order not to be regulated as an investment company under the Investment Company Act, unless we can qualify for an exclusion, we must ensure that we are engaged primarily in a business other than investing, reinvesting or trading of securities and that our activities do not include investing, reinvesting, owning, holding or trading “investment securities” constituting more than 40% of our total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We do not intend to spend a considerable amount of time actively managing the assets in the Trust Account for the primary purpose of achieving investment returns. We do not plan to buy businesses or assets with a view to resale or profit from their resale. We do not plan to buy unrelated businesses or assets or to be a passive investor.

We do not believe that our anticipated principal activities will subject us to the Investment Company Act. To this end, the Company intends to only hold the proceeds in the Trust Account and any payments under the Settlement Agreement and Notes as cash or cash equivalents but may decide to invest them in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations in the future. By restricting the investment of the proceeds to these instruments, and by having a business plan targeted at winding up (rather than on buying and selling businesses in the manner of a merchant bank or private equity fund), we intend to avoid being deemed an “investment company” within the meaning of the Investment Company Act. The IPO was not intended for persons who are seeking a return on investments in government securities or investment securities. If we do not invest the proceeds as discussed above, we may be deemed to be subject to the Investment Company Act.

In the adopting release for the final rules which became effective on July 1, 2024, the SEC provided guidance that a SPAC’s potential status as an “investment company” depends on a variety of factors, such as a SPAC’s duration, asset composition, business purpose and activities and “is a question of facts and circumstances” requiring individualized analysis. If we were deemed to be subject to compliance with and regulation under the Investment Company Act, we would be subject to additional regulatory burdens and expenses for which we have not allotted funds. Unless we are able to modify our activities so that we would not be deemed an investment company, we would either register as an investment company or wind down and abandon our efforts to complete an initial business combination.

TABLE OF CONTENTS

from the interest earned on the Trust Account established in connection with the IPO (x) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (y) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation and (ii) to reflect the Indefinite Extension.

A copy of the IMTA Amendment is set forth in Annex B to this proxy statement.

The text of the ordinary resolution is as follows:

Voting Power; Record Date

As a shareholder of the Company, you have a right to vote on certain matters affecting the Company. The proposals that will be presented at the Shareholder Meeting and upon which you are being asked to vote are summarized above and fully set forth in this proxy statement. You will be entitled to vote or direct votes to be cast at the Shareholder Meeting if you owned Ordinary Shares at the close of business on October 20, 2025, which is the Record Date for the Shareholder Meeting. You are entitled to one vote for each Ordinary Share that you owned as of the close of business on the Record Date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker, bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the Record Date, there were 21,349,863 issued and outstanding Ordinary Shares, of which 13,724,863 Class A Ordinary Shares were held by public shareholders and 7,625,000 Class F Ordinary Shares were held by the Sponsor and the Company’s independent directors. On the Record Date, there were no Class B Ordinary Shares issued and outstanding.

Recommendation of the Board

THE BOARD UNANIMOUSLY RECOMMENDS
THAT YOU VOTE “FOR” EACH OF THE PROPOSALS

Quorum

The presence, in person, virtually or by proxy, of shareholders holding one-third (1/3) in voting power of the Ordinary Shares entitled to vote at the Shareholder Meeting constitutes a quorum at the Shareholder Meeting. Abstentions will be considered present for the purposes of establishing a quorum but will not count as votes cast and therefore will have the same effect as a vote “AGAINST” the IMTA Amendment Proposal and no effect on the approval of the Articles Amendment Proposal and the Adjournment Proposal.

TABLE OF CONTENTS

The Sponsor and the Company’s independent directors, who collectively own approximately 35.7% of the issued and outstanding Ordinary Shares as of the Record Date, will count towards this quorum. As a result, no additional Ordinary Shares held by public shareholders would be required to be present at the Shareholder Meeting to achieve a quorum.

Abstentions

Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Shareholder Meeting and therefore will have the same effect as a vote “AGAINST” the IMTA Amendment Proposal and no effect on the approval of the Articles Amendment Proposal and the Adjournment Proposal.

Under the applicable rules, if a shareholder holds their shares in “street” name through a bank, broker or other nominee and the shareholder does not instruct their broker, bank or other nominee how to vote their shares on a proposal, the broker, bank or other nominee has the authority to vote the shares in its discretion on certain “routine” matters. However, banks, brokers and other nominees are not authorized to exercise their voting discretion on any “non-routine” matters. This can result in a “broker non-vote,” which occurs on a proposal when (i) a bank, broker or other nominee has discretionary authority to vote on one or more “routine” proposals to be voted on at a meeting of shareholders, (ii) there are one or more “non-routine” proposals to be voted on at the meeting for which the bank, broker or other nominee does not have authority to vote without instructions from the beneficial owner of the shares and (iii) the beneficial owner fails to provide the bank, broker or other nominee with voting instructions on a “non-routine” matter.

The Proposals are “non-routine” matters and therefore, brokers are not permitted to exercise their voting discretion with respect to these proposals. As a result, if you hold your shares in street name, your bank, brokerage firm or other nominee cannot vote your shares on any of these proposals at the Shareholder Meeting without your instruction.

Vote Required for Approval

The Class F Ordinary Shares and Class B Ordinary Shares are not entitled to redemption rights and will be excluded from the pro rata calculation used to determine the per-share redemption price. As of the date hereof, the Sponsor and the Company’s independent directors collectively hold all of the Class F Ordinary Shares or approximately 35.7% of the issued and outstanding Ordinary Shares. The Company’s officers do not own any Ordinary Shares directly. As a result, in addition to the Class F Ordinary Shares, (i) approval of the Articles Amendment Proposal will require the affirmative vote of at least 6,608,242 Public Shares (or approximately 48.1% of the Public Shares) if all Public Shares are represented at the Shareholder Meeting and cast votes, and no Public Shares if only such shares as are required to establish a quorum are represented at the Shareholder Meeting and cast votes, (ii) approval of the IMTA Amendment Proposal will require the affirmative vote of at least 6,252,411 Public Shares (or approximately 45.6% of the Public Shares), and (iii) approval of the Adjournment Proposal will require the affirmative vote of at least 3,049,932 Public Shares (or approximately 22.2% of the Public Shares) if all Public Shares are represented at the Shareholder Meeting and cast votes, and no Public Shares if only such shares as are required to establish a quorum are represented at the Shareholder Meeting and cast votes. The following table reflects the number of additional Public Shares required to approve each proposal:

Voting Your Shares

If you were a holder of record of Ordinary Shares as of the close of business on the Record Date for the Shareholder Meeting, you may vote with respect to the proposals electronically, or by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided. Your proxy card shows the number of Ordinary Shares that you own. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted.

There are two ways to vote your Ordinary Shares at the Shareholder Meeting:

Revoking Your Proxy

If you give a proxy, you may revoke it at any time before the Shareholder Meeting or at the Shareholder Meeting by doing any one of the following:

•

you may send another proxy card with a later date;

•

you may notify the Company’s Chief Executive Officer in writing to Nabors Energy Transition Corp. II, 515 West Greens Road, Suite 1200, Houston, TX 77067, before the Shareholder Meeting that you have revoked your proxy; or

•

you may attend the Shareholder Meeting, revoke your proxy, and vote electronically, as indicated above.

No Additional Matters

The Shareholder Meeting has been called only to consider and vote on the approval of the Proposals. Under the Second A&R Memorandum and Articles of Association, other than procedural matters incident to the conduct of the Shareholder Meeting, no other matters may be considered at the Shareholder Meeting if they are not included in this proxy statement, which serves as the notice of the Shareholder Meeting.

Who Can Answer Your Questions about Voting

TABLE OF CONTENTS

Redemption Rights

Pursuant to the Second A&R Memorandum and Articles of Association, holders of Public Shares may seek to redeem their shares for cash, regardless of whether they vote for or against, or whether they abstain from voting on, any of the Proposals and contingent upon the effectiveness of the implementation of the Articles Amendment, any shareholder holding Public Shares may demand that the Company redeem such shares for a full pro rata portion of the Trust Account (which, for illustrative purposes, was approximately $11.31 per Public Share as of October 23, 2025), calculated as of two business days prior to the Shareholder Meeting. If a holder properly seeks Redemption as described in this section, the Company will redeem these shares for a pro rata portion of funds deposited in the Trust Account and the holder will no longer own these shares following the Shareholder Meeting.

As a holder of Public Shares, you will be entitled to receive cash for any Public Shares to be redeemed only if you:

(i)

(ii)

submit a written request to the Transfer Agent, in which you (a) request that the Company redeem all or a portion of your Public Shares for cash, and (b) identify yourself as the beneficial holder of the Public Shares and provide your legal name, phone number and address; and

(iii)

deliver your Public Shares to the Transfer Agent, physically or electronically through DTC.

Holders must complete the procedures for electing to redeem their Public Shares in the manner described above prior to 4:00 p.m., Central Time, on November 12, 2025 (two business days prior to the initially scheduled date of the Shareholder Meeting) in order for their shares to be redeemed.

The redemption rights include the requirement that a holder must identify itself in writing as a beneficial holder and provide its legal name, phone number and address to Continental in order to validly redeem its shares.

If you hold your shares in “street name,” you will have to coordinate with your broker to have your shares certificated or delivered electronically. Shares of the Company that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through DTC’s deposit withdrawal at custodian (“ DWAC ”) system. The Transfer Agent will typically charge the tendering broker a fee and it would be up to the broker whether or not to pass this cost on to the redeeming shareholder.

The closing price of the Public Shares on October 23, 2025 was $11.35 per share. The cash held in the Trust Account as of October 23, 2025, the most recent practicable date prior to the date of this proxy statement, was approximately $155.3 million (including interest not previously released to the Company to pay taxes) ($11.31 per Public Share). Prior to exercising redemption rights, shareholders should verify the market price of Public Shares as they may receive higher proceeds from the sale of their Public Shares in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. The Company cannot assure its shareholders that they will be able to sell their Public Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when its shareholders wish to sell their shares.

If a holder of Public Shares exercises his, her or its redemption rights, then he, she or it will be exchanging Public Shares for cash and will no longer own those shares. You will be entitled to receive cash for these shares only if you properly demand Redemption by delivering your share certificate (either physically or electronically) to the Transfer Agent two business days prior to the initially scheduled date of the Shareholder Meeting.

For a discussion of material U.S. federal income tax considerations for holders of Public Shares with respect to the redemption of Public Shares as a result of the exercise of the redemption rights discussed above, see “ Material U.S. Federal Income Tax Considerations for Shareholders with Respect to a Redemption

TABLE OF CONTENTS

of Public Shares. ” The consequences of a Redemption to any particular shareholder will depend on that shareholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the exercise of your redemption rights, including the applicability and effect of U.S. federal, state, local and non-U.S. income and other tax laws in light of your particular circumstances.

Appraisal Rights

Neither Cayman Islands law nor the Second A&R Memorandum and Articles of Association provide for dissenters’ rights or appraisal rights for dissenting shareholders in connection with any of the Proposals. Accordingly, there are no dissenters’ rights or appraisal rights available to the Company’s shareholders in connection with any of the Proposals. However, holders of Public Shares may elect to have their shares redeemed in connection with the adoption of the Articles Amendment Proposal, as described under “ Redemption Rights ” above.

Proxy Solicitation Costs

The Company is soliciting proxies on behalf of the Board. This proxy solicitation is being made by mail, but also may be made by telephone or virtually. The Company has engaged Sodali to assist in the solicitation of proxies for the Shareholder Meeting. The Company and its directors, officers and employees may also solicit proxies virtually. The Company will ask banks, brokers and other institutions, nominees and fiduciaries to forward this proxy statement and the related proxy materials to their principals and to obtain their authority to execute proxies and voting instructions.

The Company will bear the entire cost of the proxy solicitation, including the preparation, assembly, printing, mailing and distribution of this proxy statement and the related proxy materials. The Company will pay Sodali a fee of $20,000, plus associated disbursements, reimburse Sodali for its reasonable out-of-pocket expenses and indemnify Sodali and its affiliates against certain claims, liabilities, losses, damages and expenses for its services as the Company’s proxy solicitor. The Company will reimburse brokerage firms and other custodians for their reasonable out-of-pocket expenses for forwarding this proxy statement and the related proxy materials to the Company’s shareholders. Directors, officers and employees of the Company who solicit proxies will not be paid any additional compensation for soliciting.

TABLE OF CONTENTS

THE ARTICLES AMENDMENT PROPOSAL

Background

The Company is a blank check company incorporated as a Cayman Islands exempted company on April 12, 2023 and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganisation or similar business combination, involving the Company and one or more businesses or entities. Our Sponsor is an affiliate of Nabors (NYSE: NBR).

On July 18, 2023, the Company consummated its IPO of 30,500,000 Units at $10.00 per Unit, including 500,000 Units that were issued pursuant to the underwriters’ partial exercise of their over-allotment option, generating gross proceeds of $305.0 million. Each Unit consists of one Class A Ordinary Share and one-half of one redeemable Public Warrant, with each whole warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share. The securities in the IPO were registered under the Securities Act of 1933, as amended (the “ Securities Act ”), on a registration statement on Form S-1 (No. 333-272810). The SEC declared the registration statement effective on July 13, 2023.

Simultaneously with the closing of the IPO, the Company consummated the sale of 9,540,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, generating gross proceeds of approximately $9.5 million.

Simultaneously with the closing of the IPO, the direct or indirect owners of the Sponsor loaned the Company an aggregate of $3,050,000, and in exchange, the Company issued unsecured promissory notes to each lender for an aggregate principal amount of $3,050,000.

Following the closing of the IPO, $308,050,000 from the net proceeds of the sale of the Units in the IPO, the sale of the Private Placement Warrants and the Overfunding Loans were deposited in the Trust Account.

On July 16, 2025, the Company convened an extraordinary general meeting (the “ First Extension Meeting ”) and, among other things, the Company’s shareholders approved and adopted by special resolution an amendment and restatement of the Company’s then-effective Amended and Restated Memorandum and Articles of Association, with effect from such date as determined by the Board in its sole discretion, to allow the Board, without another shareholder vote, to elect to extend the date by which the Company has to consummate an initial business combination from July 18, 2025 up to twelve times for an additional one month each time to July 18, 2026 (or within 36 months from the consummation of the IPO), provided that the Sponsor (or its affiliates or designees) deposited into the Trust Account for each monthly extension $250,000 in exchange for a non-interest bearing, unsecured promissory note.

At the First Extension Meeting, shareholders holding 16,775,137 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account (the “ First Extension Redemption ”). As a result, approximately $186.7 million (or approximately $11.13 per share) was removed from the Trust Account to pay such holders, and 13,724,863 Public Shares remain outstanding. Following the First Extension Meeting, the Sponsor has (or its affiliates or designees have) deposited an aggregate of $1.0 million into the Trust Account to extend the Termination Date from July 18, 2025 to November 18, 2025 pursuant to the Second A&R Memorandum and Articles of Association.

Overview

In connection with the Settlement Agreement, the Company no longer intends to pursue an initial business combination or the e2 Business Combination and intends to indefinitely continue its existence solely for purposes of receiving all payments under the Settlement Agreement and the Notes, satisfying its liabilities, obligations, fees and expenses incurred in connection with the transactions contemplated by the Business Combination Agreement and IPO and subsequently liquidating and dissolving. Accordingly, the Company is proposing to amend its Second A&R Memorandum and Articles of Association to delete Article 49 (Business Combination), other than Article 49.7, in its entirety, and amend Article 49.7 to (i) remove the obligations under the Second A&R Memorandum and Articles of Association for the Sponsor (or its affiliates or designees) to deposit additional funds of $250,000 into the Trust Account for each

TABLE OF CONTENTS

Monthly Extension Period in exchange for a non-interest bearing, unsecured promissory note and (ii) allow the Company to remain in existence indefinitely to receive the payments under each Note and any Trigger Event Payments.

As contemplated by the Second A&R Memorandum and Articles of Association, the holders of Public Shares may elect to redeem all or a portion of their Public Shares in exchange for their pro rata portion of the funds held in the Trust Account if the Articles Amendment is implemented. The Company may (and intends to) accept Redemptions in the event the Articles Amendment Proposal is not approved and the Articles Amendment is not implemented.

A copy of the form of the proposed Articles Amendment is attached to this proxy statement as Annex A .

On October 23, 2025, the most recent practicable date prior to the date of this proxy statement, the redemption price per share was approximately $11.31, based on the aggregate amount on deposit in the Trust Account of approximately $155.3 million as of October 23, 2025 (including interest not previously released to the Company to pay taxes), divided by the total number of then outstanding Public Shares. The redemption price per share in connection with the Articles Amendment Proposal will be calculated based on the aggregate amount on deposit in the Trust Account two business days prior to the Shareholder Meeting. The closing price of the Public Shares on Nasdaq on October 23, 2025, was $11.35. Accordingly, if the market price of the Public Shares were to remain the same until the date of the Shareholder Meeting, exercising redemption rights would result in a public shareholder receiving approximately $0.04 less per share than if the shares were sold in the open market (based on the current per share redemption price as of October 23, 2025). The Company cannot assure shareholders that they will be able to sell their Public Shares in the open market, even if the market price per share is lower than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

Reasons for the Articles Amendment Proposal

The Company and its officers and directors agreed that they would not seek to amend the Second A&R Memorandum and Articles of Association unless the Company provided holders of its Public Shares with the right to seek Redemption of their Public Shares in connection therewith. The Board believes that it is in the best interests of the Company to have the Company’s shareholders approve the Articles Amendment Proposal to allow the Company to remain in existence indefinitely to receive payments under the Settlement Agreement and Notes and to allow the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees or expenses incurred by or on behalf of the Company since its formation.

If the Articles Amendment Proposal is Not Approved

If the Articles Amendment Proposal is not approved, the Company may in the future ask shareholders to approve proposals similar to the Proposals. The Sponsor has informed the Board that it does not intend to fund, nor does it intend to cause any of its affiliates or designees to fund, any further Monthly Extension Payments. If any of the Proposals are not approved and future Monthly Extension Payments are not made, the Company may be wound up in accordance with the Second A&R Memorandum and Articles of Association: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account not previously released to the Company to pay its taxes (net of any taxes payable by the Company and less up to $100,000 of interest that may be released to the Company to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Board, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. In such an event, the Public Shares will have been redeemed, and will not be entitled to participate in any distribution of proceeds of payments under the Settlement Agreement or the

TABLE OF CONTENTS

Notes. There will be no distribution from the Trust Account with respect to the Company’s warrants, which will expire worthless in the event of our winding up.

If the Articles Amendment Proposal is Approved

If the Articles Amendment Proposal is approved and implemented, the Company will file the Articles Amendment with the Registrar of Companies in the Cayman Islands in the form attached to this proxy statement as Annex A . Holders of Public Shares remaining after the Redemptions will not have another opportunity to redeem their Public Shares for their pro rata portion of the funds available in the Trust Account. The Company does not intend to pursue an initial business combination or the e2 Business Combination at this time. Any shareholder that does not redeem its Public Shares in connection herewith is expected to receive (i) a pro rata portion of the funds available in the Trust Account at the time the Company winds up, which is expected to constitute, for each Public Share, (x) the proceeds of the Trust Account, less (y) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment, and (ii) a pro rata portion of any payments under the Settlement Agreement and the Notes, net of fees and expenses paid or to be paid by or on behalf of the Company. Up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and up to 100% of the interest accrued from the date of the IMTA Amendment may be withdrawn from the interest earned on the Trust Account to pay fees and expenses incurred by or on behalf of the Company since its formation, including those incurred in connection with the Action, and the remainder of the funds will be held until the time the Company liquidates and dissolves as and when determined by the Board, at which time the remaining funds in the Trust Account will be used to redeem the holders of Public Shares remaining after the Redemption in connection with the Shareholder Meeting. As of the date of this proxy statement, the Company has (i) approximately $10.0 million of incurred fees and expenses and (ii) approximately $4.1 million in Overfunding Loans and Monthly Extension Payments. The Company expects that following the Redemptions it will not meet the listing standards of Nasdaq and, accordingly, expects to be delisted from Nasdaq. The Company will remain in existence indefinitely or until such time as the Board determines that the Company liquidate and dissolve.

Interests of the Sponsor and the Company’s Directors and Officers

When considering the recommendation of the Board, the Company’s shareholders should be aware that, aside from their interests as direct or indirect shareholders, the Sponsor and certain members of the Board and officers of the Company have interests that are different from, or in addition to, those of other shareholders generally. The Board was aware of and considered these interests, among other matters, in recommending to the Company’s shareholders that they approve the Articles Amendment Proposal and the IMTA Amendment Proposal. The Company’s shareholders should take these interests into account in deciding whether to approve the Articles Amendment Proposal and the IMTA Amendment Proposal:

•

the fact that, under the current Second A&R Memorandum and Articles of Association, the Sponsor (or its affiliates or designees) is required to deposit into the Trust Account $250,000 for each Monthly Extension Period which will no longer be required if the Articles Amendment Proposal is approved and the Articles Amendment is implemented;

•

the fact that on October 14, 2025, Nabors and certain affiliates of Nabors entered into a settlement agreement with e2 pursuant to which e2 shall refund to Nabors Corporate Services, Inc. $1,631,500 paid in respect of certain purchase orders (the “ Purchase Orders ”), without interest, no later than December 1, 2025. If the refund is not paid in full by December 1, 2025, interest shall accrue at 10% per annum. The parties agreed to terminate all agreements relating to the Purchase Orders;

•

the fact that Nabors Lux (which certain of the Company’s officers are affiliated with) and certain of the Company’s officers and directors paid an aggregate of $8,727,510 for 8,727,510 Private Placement Warrants, each of which is exercisable 30 days following the closing of an initial business combination for one Class A Ordinary Share at $11.50 per share. If the Articles Amendment Proposal is not approved and the Sponsor does not pay, or cause an affiliate to pay, the Monthly Extension Payments,

TABLE OF CONTENTS

the Company may be forced to initiate the process of winding up, and the portion of the proceeds from the sale of the Private Placement Warrants that was deposited into the Trust Account will be used to redeem the public shareholders and the Private Placement Warrants will be worthless;

•

the fact that Nabors Lux and certain of the Company’s officers and directors loaned an aggregate of $2,787,490 of the $3,050,000 Overfunding Loans to the Company in connection with the IPO, which loans will not be repaid if the Company is forced to initiate the process of winding up;

•

the fact that the Sponsor has invested in the Company $25,000 for 7,475,000 Class F Ordinary Shares. Assuming a trading price of $11.35 per Class A Ordinary Share (based upon the closing price of the Class A Ordinary Shares on Nasdaq on October 23, 2025), the 7,475,000 Class F Ordinary Shares would have an implied aggregate market value of $84,841,250;

•

the fact that the Company’s independent directors own an aggregate of 150,000 Class F Ordinary Shares that, upon forfeiture and surrender by the Sponsor, were issued to the Company’s independent directors for an aggregate of $290. Assuming a trading price of $11.35 per Class A Ordinary Share (based upon the closing price of the Class A Ordinary Shares on Nasdaq on October 23, 2025), the 150,000 Class F Ordinary Shares would have an implied aggregate market value of $1,702,500;

•

the fact that the Sponsor and the Company’s officers and directors have agreed to waive their rights to distributions from the Trust Account with respect to any Ordinary Shares (other than Public Shares) held by them if the Articles Amendment Proposal is not approved and the Company fails to complete an initial business combination on or before the Termination Date;

•

the indemnification of the Company’s existing officers and directors and the liability insurance maintained by the Company;

•

the fact that the Sponsor (or its affiliates or designees) deposited an aggregate of $1.0 million into the Trust Account in order to extend the Termination Date from July 18, 2025 to November 18, 2025 pursuant to the Second A&R Memorandum and Articles of Association, and, if the Company is forced to initiate the process of winding up, such loans will be repaid in cash only from funds held outside the Trust Account, if any. If the Articles Amendment Proposal and the IMTA Amendment Proposal are approved, the Company may use funds withdrawn from interest earned on the Trust Account to pay such loans. Any payments received under the Settlement Agreement and the Notes will first be used to pay the loans;

•

the fact that up to $0.50 per Public Share that is not redeemed in connection with the Shareholder meeting and up to 100% of the interest accrued from the date of the IMTA Amendment and payments received under the Settlement Agreement and the Notes will be used to pay the Company’s fees and expenses, including reimbursement of any loans extended, fees due or out-of-pocket expenses by the Sponsor and the Company’s officers and directors, if the Proposals are approved. As of the date of this proxy statement, there are no loans extended, fees due or outstanding out of pocket expenses for which the Company’s officers and directors or the Sponsor are awaiting reimbursement, except as described herein;

•

the fact that the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent auditors) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (i) $10.10 per Public Share or (ii) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of interest withdrawn to pay taxes. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under our indemnity of the underwriters of our IPO against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims; and

•

the fact that the Sponsor and the Company’s officers and directors, and their respective affiliates, will be reimbursed for out-of-pocket expenses incurred in connection with activities on the Company’s

TABLE OF CONTENTS

behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations, which expenses were approximately $0 as of October 20, 2025, the record date for the Shareholder Meeting. As of October 24, 2025, the amount in reimbursement the Sponsor and the Company’s officers and directors, and their respective affiliates may receive is $0.

Redemption Rights

Pursuant to the Second A&R Memorandum and Articles of Association, holders of Ordinary Shares may seek to redeem their shares for cash, regardless of whether they vote for or against, or whether they abstain from voting on, any of the Proposals. In connection with the Articles Amendment Proposal and contingent upon the effectiveness of the implementation of the Articles Amendment, any shareholder holding Public Shares may demand that the Company redeem such shares for a full pro rata portion of the Trust Account (which, for illustrative purposes, was approximately $11.31 per share as of October 23, 2025), calculated as of two business days prior to the Shareholder Meeting. If a holder properly seeks Redemption as described in this section and the Articles Amendment Proposal is approved and implemented, the Company will redeem these shares for a pro rata portion of funds deposited in the Trust Account and the holder will no longer own these shares following the Shareholder Meeting.

As a holder of Public Shares, you will be entitled to receive cash for any Public Shares to be redeemed only if you:

(i)

(ii)

(iii)

deliver your Public Shares to the Transfer Agent, physically or electronically through DTC.

If you hold the shares in “street name,” you will have to coordinate with your broker to have your shares certificated or delivered electronically. Shares of the Company that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through DTC’s DWAC system. The Transfer Agent will typically charge the tendering broker a fee and it would be up to the broker whether or not to pass this cost on to the redeeming shareholder.

The closing price of the Public Shares on October 23, 2025, the most recent practicable date prior to the date of this proxy statement, was $11.35 per share. The cash held in the Trust Account on such date was approximately $155.3 million (including interest not previously released to the Company to pay taxes) ($11.31 per Public Share). Prior to exercising redemption rights, shareholders should verify the market price of Public Shares as they may receive higher proceeds from the sale of their Public Shares in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. The Company cannot assure its shareholders that they will be able to sell their Public Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when its shareholders wish to sell their shares.

If a holder of Public Shares exercises his, her or its redemption rights, then he, she or it will be exchanging its Public Shares for cash and will no longer own those shares. You will be entitled to receive cash for these

TABLE OF CONTENTS

shares only if you properly demand Redemption by delivering your share certificate (either physically or electronically) to the Transfer Agent two business days prior to the initially scheduled date of the Shareholder Meeting.

Vote Required for Approval

The approval of the Articles Amendment Proposal requires a special resolution under Cayman Islands law, which is a resolution passed by a majority of at least two-thirds (2/3) of such shareholders of the Company as, being entitled to do so, vote in person or by proxy at the Shareholder Meeting. Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Shareholder Meeting and therefore will have no effect on the approval of the Articles Amendment Proposal.

As of the date hereof, the Sponsor and the Company’s independent directors collectively hold all of the Class F Ordinary Shares or approximately 35.7% of the issued and outstanding Ordinary Shares. The Company’s officers do not own any Ordinary Shares directly. As a result, in addition to the Class F Ordinary Shares, approval of the Articles Amendment Proposal will require the affirmative vote of at least 6,608,242 Public Shares (or approximately 48.1% of the Public Shares) if all Public Shares are represented at the Shareholder Meeting and cast votes, and no Public Shares if only such shares as are required to establish a quorum are represented at the Shareholder Meeting and cast votes.

Full Text of the Articles Amendment Proposal

The full text of the resolution to be voted upon is as follows:

“ RESOLVED , as a special resolution, with effect from such date as may be determined by the Company’s board of directors in their sole discretion (such date being on or after the date of passing of this resolution), the Company’s second amended and restated memorandum and articles of association currently in effect be amended by (i) deleting Article 49 (Business Combination), other than Article 49.7, in its entirety and (ii) extending the date by which the Company has to consummate an initial business combination indefinitely:”

Recommendation of the Board

As discussed above, after careful consideration of all relevant factors, the Board has determined that the Articles Amendment Proposal is in the best interests of the Company and its shareholders. The Board has approved and declared advisable adoption of the Articles Amendment Proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE
ARTICLES AMENDMENT PROPOSAL.

The existence of financial and personal interests of our directors and officers may result in a conflict of interest on the part of one or more of the directors or officers between what he, she or they may believe is in the best interests of the Company and its shareholders and what he, she or they may believe is best for himself, herself or themselves in determining to recommend that shareholders vote for the proposals. See the section entitled “ The Articles Amendment Proposal — Interests of the Sponsor and the Company’s Directors and Officers ” for a further discussion.

TABLE OF CONTENTS

THE IMTA AMENDMENT PROPOSAL

Overview

The Company is proposing to amend and restate the Trust Agreement (x) to permit the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation and (y) to reflect the Indefinite Extension.

A copy of the form of the proposed IMTA Amendment is attached to this proxy statement as Annex B .

Reasons for the IMTA Amendment Proposal

The purpose of the IMTA Amendment Proposal is to allow the Company to withdraw from the interest earned on the Trust Account (i) up to $0.50 per Public Share that is not redeemed in connection with the Shareholder Meeting and (ii) up to 100% of the interest accrued from the date of the IMTA Amendment, in each case, in order to pay for fees and expenses incurred by or on behalf of the Company since its formation.

If the IMTA Amendment Proposal is Not Approved

If the IMTA Amendment Proposal is not approved, the Company will not be able to withdraw funds to pay for its fees and expenses. The Company may in the future ask shareholders to approve a proposal similar to the IMTA Amendment Proposal.

If the IMTA Amendment Proposal is Approved

If the IMTA Amendment Proposal is approved and implemented, the Company will execute the IMTA Amendment in the form attached to this proxy statement as Annex B .

You are not being asked to vote on an initial business combination at this time. The Company does not intend to pursue an initial business combination at this time.

Vote Required for Approval

Pursuant to the Trust Agreement, the approval of the IMTA Amendment Proposal requires the affirmative vote of the holders of at least sixty-five percent (65%) of the issued and outstanding Ordinary Shares, voting together as a single class. Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Shareholder Meeting and therefore will have the same effect as a vote “AGAINST” the IMTA Amendment Proposal.

Recommendation of the Board

As discussed above, after careful consideration of all relevant factors, the Board has determined that the IMTA Amendment Proposal is in the best interests of the Company and its shareholders. The Board has approved and declared advisable adoption of the IMTA Amendment Proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” THE IMTA
AMENDMENT PROPOSAL.

TABLE OF CONTENTS

THE ADJOURNMENT PROPOSAL

Overview

The Company is asking shareholders to approve the adjournment of the Shareholder Meeting to a later date or dates or indefinitely if necessary to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Shareholder Meeting, there are insufficient Ordinary Shares represented (either in person, virtually or by proxy) to constitute a quorum necessary to conduct business at the Shareholder Meeting or to approve the Articles Amendment Proposal or the IMTA Amendment Proposal.

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved by the Company’s shareholders, the Board may not be able to adjourn the Shareholder Meeting to a later date in the event that, based on the tabulated votes, there are insufficient Ordinary Shares represented (either in person, virtually or by proxy) at the time of the Shareholder Meeting to approve the Articles Amendment Proposal or the IMTA Amendment Proposal or if the Board otherwise determined before the Shareholder Meeting that additional time is necessary to obtain the requisite shareholder votes or no longer desirable to proceed with the Articles Amendment Proposal or the IMTA Amendment Proposal, in which case the Adjournment Proposal will be the only proposal presented at the Shareholder Meeting. In such events, the Articles Amendment would not be implemented.

Vote Required for Approval

The approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, which is a resolution passed by a simple majority of the shareholders of the Company as, being entitled to do so, vote in person or, where proxies are allowed, by proxy at the Shareholder Meeting. Abstentions will be considered present for the purposes of establishing a quorum but will not constitute votes cast at the Shareholder Meeting and therefore will have no effect on the approval of the Adjournment Proposal.

As of the date hereof, the Sponsor and the Company’s independent directors collectively hold all of the Class F Ordinary Shares or approximately 35.7% of the issued and outstanding Ordinary Shares. The Company’s officers do not own any Ordinary Shares directly. As a result, in addition to the Class F Ordinary Shares, approval of the Adjournment Proposal will require the affirmative vote of at least 3,049,932 Public Shares (or approximately 22.2% of the Public Shares) if all Public Shares are represented at the Shareholder Meeting and cast votes, and no Public Shares if only such shares as are required to establish a quorum are represented at the Shareholder Meeting and cast votes.

Full Text of the Resolution

The full text of the resolution to be voted upon is as follows:

“ RESOLVED , as an ordinary resolution, to adjourn the Shareholder Meeting to a later date or dates or indefinitely, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the Shareholder Meeting, there are insufficient Class A ordinary shares, par value $0.0001 per share, Class B ordinary shares, par value $0.0001 per share, and Class F ordinary shares, par value $0.0001 per share, in the share capital of the Company represented (either in person, virtually or by proxy) at the time of the Shareholder Meeting to approve the Articles Amendment Proposal and the IMTA Amendment Proposal, or if the Board otherwise determined before the Shareholder Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposal or the IMTA Amendment Proposal.”

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR
SHAREHOLDERS WITH RESPECT TO A REDEMPTION OF PUBLIC SHARES

The following is a discussion of the material U.S. federal income tax considerations for U.S. Holders (as defined below) of Public Shares (i) who elect to have their Public Shares redeemed for cash if the Articles Amendment Proposal is implemented (or if the Company otherwise determines to accept Redemptions in the event the Articles Amendment Proposal is not approved and the Articles Amendment Proposal is not implemented) or (ii) whose Public Shares are redeemed in connection with a future winding up of the Company. This discussion applies only to Public Shares that are held by U.S. Holders as a “capital asset” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “ Code ”), for U.S. federal income tax purposes (generally, property held for investment). This discussion is based on the provisions of the Code, U.S. Treasury regulations, administrative rules and judicial decisions, all as in effect on the date hereof, and all of which are subject to change or differing interpretations, possibly with retroactive effect. Any such change or differing interpretation could affect the accuracy of the statements set forth herein. We have not sought, and do not intend to seek, any rulings from the U.S. Internal Revenue Service (“ IRS ”) with respect to the statements made and the positions or conclusions described in this discussion. Such statements, positions and conclusions are not free from doubt, and there can be no assurance that your tax advisor, the IRS or a court will agree with such statements, positions and conclusions.

The following discussion does not purport to be a complete analysis of all potential tax effects to holders of Public Shares resulting from any redemptions of Public Shares. Furthermore, it does not address all aspects of U.S. federal income taxation that may be relevant to particular holders in light of their personal circumstances. In addition, this summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any U.S. state or local or non-U.S. tax laws, any tax treaties or any tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws, such as:

•

banks, insurance companies or other financial institutions;

•

tax-exempt or governmental organizations;

•

dealers in securities or foreign currencies;

•

persons whose functional currency is not the U.S. dollar;

•

traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

•

partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;

•

persons deemed to sell Public Shares under the constructive sale provisions of the Code;

•

persons that acquired Public Shares through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

•

persons that hold Public Shares as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction or other integrated investment or risk reduction transaction;

•

certain former citizens or long-term residents of the United States;

•

persons that actually or constructively hold 5% or more (by vote or value) of any class of the Company’s shares;

•

holders of our Class F Ordinary Shares and Private Placement Warrants; and

•

our officers or directors.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Public Shares, the tax treatment of a partner in such partnership generally will depend upon the status of the partner, upon the activities of the partnership and upon certain determinations made at the partner level. Accordingly, partners in partnerships (including entities or arrangements treated as

TABLE OF CONTENTS

partnerships for U.S. federal income tax purposes) holding Public Shares should consult with their own tax advisors regarding the U.S. federal income tax consequences to them relating to the matters discussed below.

HOLDERS SHOULD CONSULT WITH THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS (INCLUDING ANY POTENTIAL FUTURE CHANGES THERETO) TO THEIR PARTICULAR SITUATIONS, AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY U.S. STATE OR LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

U.S. Holders

For purposes of this discussion, a “ U.S. Holder ” is a holder that, for U.S. federal income tax purposes, is:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust (i) the administration of which is subject to the primary supervision of a U.S. court and which has one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (ii) that has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

Tax Effects for U.S. Holders of a Redemption of Public Shares

Generally

Subject to the passive foreign investment company (“ PFIC ”) rules discussed below, in the event that a U.S. Holder’s Public Shares are redeemed pursuant to the redemption provisions described in the subsection of this proxy statement entitled “ The Articles Amendment Proposal — Redemption Rights ”, the treatment of such a redemption for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of Public Shares under Section 302 of the Code. If the redemption pursuant to the redemption provisions described in the subsection of this proxy statement entitled “ The Articles Amendment Proposal — Redemption Rights ” qualifies as a sale of Public Shares, the U.S. Holder will be treated as described below under “— Gain or Loss on Redemption Treated as a Sale of Public Shares .” If the redemption pursuant to the redemption provisions described in the subsection of this proxy statement entitled “ The Articles Amendment Proposal — Redemption Rights ” does not qualify as a sale of Public Shares, the U.S. Holder will be treated as receiving a distribution from the Company with the tax consequences described below under “— Taxation of Redemption Treated as a Distribution .” Whether a redemption qualifies for sale treatment will depend largely on the total number of our shares treated as held directly, indirectly or constructively by the U.S. Holder (including any shares constructively owned by the U.S. Holder as a result of owning the Company’s warrants) relative to all of the Company’s shares outstanding both before and after the redemption. The redemption of Public Shares generally will be treated as a sale of Public Shares (rather than as a distribution from the Company) if the redemption (i) is “substantially disproportionate” with respect to the U.S. Holder, (ii) results in a “complete termination” of the U.S. Holder’s interest in the Company or (iii) is “not essentially equivalent to a dividend” with respect to the U.S. Holder. These tests are explained more fully below.

In determining whether any of the foregoing tests is satisfied, a U.S. Holder takes into account not only Public Shares actually owned by the U.S. Holder, but also our shares that are constructively owned by it. A U.S. Holder may constructively own, in addition to stock owned directly, stock owned by certain related individuals and entities in which the U.S. Holder has an interest or that have an interest in such U.S. Holder, as well as any stock the U.S. Holder has a right to acquire by exercise of an option, which would generally include the Public Shares that could be acquired pursuant to the exercise of the Company’s warrants.

TABLE OF CONTENTS

In order to meet the substantially disproportionate test, the percentage of the Company’s outstanding voting stock actually and constructively owned by the U.S. Holder immediately following the redemption of Public Shares must, among other requirements, be less than 80% of the percentage of the Company’s outstanding voting shares actually and constructively owned by the U.S. Holder immediately before the redemption. Since the Public Shares do not participate in the election or appointment of the Company’s board of directors prior to the initial business combination, the Public Shares might not be treated as voting shares for this purpose and, consequently, this substantially disproportionate test might not be applicable.

There will be a complete termination of a U.S. Holder’s interest if either (i) all of the Public Shares actually and constructively owned by the U.S. Holder are redeemed or (ii) all of the Public Shares actually owned by the U.S. Holder are redeemed, the U.S. Holder is eligible to waive (and effectively waives in accordance with specific rules) the attribution of stock owned by certain family members and the U.S. Holder does not constructively own any other of our shares (including shares constructively owned by the U.S. Holder as a result of owning the Company’s warrants).

The redemption of Public Shares will not be essentially equivalent to a dividend if a U.S. Holder’s redemption results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in the Company. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in the Company will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.” U.S. Holders should consult with their own tax advisors as to the tax consequences of a redemption pursuant to the redemption provisions described in the subsection of this proxy statement entitled “ The Articles Amendment Proposal — Redemption Rights ”.

If none of the foregoing tests is satisfied, the redemption pursuant to the redemption provisions described in the subsection of this proxy statement entitled “ The Articles Amendment Proposal — Redemption Rights ” will be treated as a distribution from the Company and the tax considerations will be as described below under “— Taxation of Redemption Treated as a Distribution .” After the application of those rules, any remaining tax basis of a U.S. Holder in the redeemed Public Shares will be added to the U.S. Holder’s adjusted tax basis in its remaining Public Shares, or, if it has none, to the U.S. Holder’s adjusted tax basis in its Company warrants or possibly in other Public Shares constructively owned by it.

A redemption of a U.S. Holder’s Public Shares in connection with a future winding up of the Company would generally be expected to be treated as a taxable sale in the manner described below under “— Gain or Loss on Redemption Treated as a Sale of Public Shares ”.

Gain or Loss on Redemption Treated as a Sale of Public Shares

Subject to the PFIC rules discussed below, if a redemption of a U.S. Holder’s Public Shares is treated as a sale of such Public Shares, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between (i) the amount of cash received by such U.S. Holder in such redemption and (ii) such U.S. Holder’s adjusted tax basis in its Public Shares redeemed therefor. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for its Public Shares redeemed exceeds one year. It is unclear, however, whether the redemption rights with respect to the Public Shares may be deemed to be a limitation of a shareholder’s risk of loss and suspend the running of the applicable holding period of such stock for this purpose. If the running of the holding period for the Public Shares is suspended, U.S. Holders may not be able to satisfy the one-year holding period requirement for long-term capital gain treatment with respect to their Public Shares. If the one-year holding period requirement is not satisfied, any gain on the redemption of Public Shares would be short-term capital gain that is taxed at regular ordinary income tax rates. Long-term capital gains of certain non-corporate U.S. Holders, including individuals, are generally subject to U.S. federal income tax at reduced rates. The deductibility of capital losses is subject to limitations.

U.S. Holders who hold different blocks of Public Shares (including as a result of holding different blocks of Public Shares purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

TABLE OF CONTENTS

Taxation of Redemption Treated as a Distribution

If a redemption of a U.S. Holder’s Public Shares is not treated as a sale of such Public Shares, the U.S. Holder generally will be treated as receiving a distribution of cash from the Company. Any such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from the Company’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of current and accumulated earnings and profits will constitute a non-taxable return of capital to the extent of a U.S. Holder’s adjusted tax basis in its Public Shares that will be applied against and reduce (but not below zero) the U.S. Holder’s adjusted tax basis in its Public Shares. Any remaining excess will be treated as gain realized on the sale or other disposition of Public Shares and will be treated as described above under “— Gain or Loss on Redemption Treated as a Sale of Public Shares .”

Any portion of a distribution that is treated as a dividend paid by us will be taxable to a corporate U.S. Holder at regular rates and will not be eligible for the dividends-received deduction generally allowed to domestic corporations in respect of dividends received from other domestic corporations. As discussed below, because the Company believes that it may be considered a PFIC, and if it is so treated, any portion of a distribution that is treated as a dividend paid to a non-corporate U.S. Holder generally will not constitute a “qualified dividend” eligible for the lower applicable long-term capital gains rate. U.S. Holders should consult with their own tax advisors regarding the availability of the dividends received deduction or the lower preferential income tax rate for qualified dividend income for any redemption treated as a distribution.

Passive Foreign Investment Company Rules

In general, a foreign (i.e., non-U.S.) corporation will be treated as a PFIC with respect to a U.S. Holder in any taxable year in which, after applying certain look-through rules, either: (i) at least 75% of its gross income for such taxable year consists of passive income (e.g., dividends, interest, rents (other than rents derived from the active conduct of a trade or business), and gains from the disposition of passive assets); or (ii) the average percentage (ordinarily averaged quarterly over the year) by value of its assets during such taxable year that produce or are held for the production of passive income is at least 50%.

Because the Company is a blank-check company with no current active business, based upon the composition of our income and assets, and upon review of our financial statements, the Company believes that it may be considered a PFIC for the 2023 and 2024 taxable years and may be considered a PFIC for its current taxable year. Although our PFIC status is determined in each taxable year, an initial determination that we are a PFIC will generally apply for subsequent years to a U.S. Holder who held (or is deemed to have held) Public Shares while we were a PFIC, whether or not we are treated as a PFIC in those subsequent years.

If we are treated as a PFIC for any taxable year in which a U.S. Holder holds Public Shares and the U.S. Holder did not make either a timely qualified electing fund (“ QEF ”) election or a mark-to-market election (in either case, as described below), such U.S. Holder generally will be subject to special rules with respect to (i) any gain realized on the sale or other disposition of its Public Shares and (ii) any “excess distribution” (generally, the portion of any distributions received by such U.S. Holder during a taxable year in excess of 125% of the average annual distributions received by such U.S. Holder during the three preceding taxable years or, if shorter, such U.S. Holder’s holding period for the Public Shares). Under these rules:

•

the U.S. Holder’s gain or excess distribution will be allocated ratably over the U.S. Holder’s holding period for the Public Shares;

•

the amount allocated to the U.S. Holder’s taxable year in which the U.S. Holder realized the gain or received the excess distribution, or to the portion of the U.S. Holder’s holding period prior to the first day of our first taxable year in which we were a PFIC, will be taxed as ordinary income; and

•

the amount allocated to each of the other taxable years (or portions thereof) of the U.S. Holder will be subject to tax at the highest tax rate in effect for the U.S. Holder in that year, and an interest charge for the deemed deferral benefit will be imposed with respect to the resulting tax attributable to each such other taxable year (or portion thereof).

The impact of the foregoing PFIC rules on a U.S. Holder with respect to a redemption of Public Shares will depend on whether such U.S. Holder makes or has made a timely and valid QEF election (if

TABLE OF CONTENTS

eligible to do so) in the first taxable year in which the U.S. Holder held (or was deemed to hold) Public Shares in which we are classified as a PFIC or, if in a later taxable year, by making a timely and valid QEF election together with a purging election. A U.S. Holder that has made a timely QEF election with respect to its Public Shares will generally recognize capital gain or loss on the sale or other disposition of its Public Shares (including upon a redemption of Public Shares that is treated as a sale of Public Shares), and no additional tax or interest charge will be imposed under the PFIC rules.

Generally, a QEF election should be made on or before the due date for filing such U.S. Holder’s U.S. federal income tax return for such taxable year. A QEF election is made on a shareholder-by-shareholder basis (and, once made, can be revoked only with the consent of the IRS) and generally requires such U.S. Holder to include annually in gross income its pro rata share of the ordinary earnings (as ordinary income) and net capital gains (as long-term capital gain), if any, of the Company, regardless of whether the Company makes distributions to such U.S. Holder. However, in order to comply with the QEF election requirements, a U.S. Holder must receive a PFIC annual information statement from the Company. If we determine we are a PFIC for any taxable year, upon written request by a U.S. Holder, we will endeavor to provide to such U.S. Holder such information as the IRS may require, including a PFIC annual information statement, in order to enable such U.S. Holder to make and maintain a QEF election, but there is no assurance that we will timely provide such required information. There is also no assurance that we will have timely knowledge of our status as a PFIC in the future or of the required information to be provided.

The impact of the PFIC rules on a U.S. Holder with respect to a redemption of Public Shares may alternatively depend on whether such U.S. Holder is eligible to and makes a timely and valid mark-to-market election with respect to its Public Shares. No assurance can be given that the Public Shares are considered to be “marketable stock” (which generally would include stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including Nasdaq (on which the Public Shares have been listed but from which the Company expects to be delisted following the Shareholder Meeting as a result of the Redemptions)) for purposes of the mark-to-market election. If such an election is available and has been made by a U.S. Holder, such U.S. Holder generally will not be subject to the PFIC rules described above. However, if the mark-to-market election is made by a U.S. Holder after the first taxable year of the U.S. Holder in which the U.S. Holder holds (or is deemed to hold) Public Shares and in which we are classified as a PFIC, then the PFIC rules will continue to apply to certain dispositions of, distributions on and other amounts taxable with respect to the Public Shares (including upon a redemption of Public Shares pursuant to the redemption provisions described in the subsection of this proxy statement entitled “ The Articles Amendment Proposal — Redemption Rights ” or in connection with a future winding up of the Company).

The rules dealing with PFICs and with the QEF, purging and mark-to-market elections are very complex, are affected by various factors in addition to those described above, and their application is uncertain. Accordingly, U.S. Holders of Public Shares are strongly urged to consult with their own tax advisors regarding the application of the PFIC rules to them in their particular circumstances and any resulting tax consequences.

Information Reporting and Backup Withholding

Information reporting requirements generally will apply to amounts received by a U.S. Holder unless the U.S. Holder is an exempt recipient and certifies to such exempt status. Backup withholding may apply to such amounts if the U.S. Holder fails to provide a taxpayer identification number or a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn).

Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund generally may be obtained provided that the required information is timely furnished to the IRS.

BUSINESS OF THE COMPANY AND CERTAIN INFORMATION ABOUT THE COMPANY

References in this section to “we,” “our,” or “us” refer to Nabors Energy Transition Corp. II.

General

We are a blank check company incorporated on April 12, 2023 as a Cayman Islands exempted company and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganisation or similar business combination, involving the Company and one or more businesses or entities, which we refer to throughout this proxy statement as our initial business combination. We are an early stage and emerging growth company and, as such, we are subject to all of the risk associated with early stage and emerging growth companies. We have also neither engaged in any operations nor generated any revenue to date.

Our Sponsor is an affiliate of Nabors, which owns and operates one of the world’s largest land-based drilling rig fleets and provides offshore platform rigs and related services in the United States and several international markets.

IPO and Private Placement

On July 18, 2023, the Company consummated its IPO of 30,500,000 Units at $10.00 per Unit, generating gross proceeds of approximately $305.0 million. Each Unit consists of one Class A Ordinary Share and one-half of one redeemable Public Warrant, with each whole warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share. The securities in the IPO were registered under the Securities Act, on a registration statement on Form S-1 (No. 333-272810). The SEC declared the registration statement effective on July 13, 2023.

Simultaneously with the closing of the IPO, the direct or indirect owners of the Sponsor loaned the Company an aggregate of $3.05 million, and in exchange, the Company issued unsecured promissory notes to each lender for an aggregate principal amount of $3.05 million.

Following the closing of the IPO, $308,050,000 from the net proceeds of the sale of the Units in the IPO, the sale of the Private Placement Warrants and the Overfunding Loans were placed in a Trust Account, and invested in U.S. government securities, within the meaning set forth in the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, or in an interest bearing demand deposit account until the earlier of: (i) the completion of its initial business combination and (ii) the distribution of the Trust Account.

Prior Extensions

On July 16, 2025, the Company convened the First Extension Meeting and, among other things, the Company’s shareholders approved and adopted by special resolution an amendment and restatement of the Company’s then-effective Amended and Restated Memorandum and Articles of Association, with effect from such date as determined by the Board in its sole discretion, to allow the Board, without another shareholder vote, to elect to extend the date by which the Company has to consummate an initial business combination from July 18, 2025 up to twelve times for an additional one month each time to July 18, 2026 (or within 36 months from the consummation of the IPO), provided that the Sponsor (or its affiliates or designees) deposited into the Trust Account for each monthly extension $250,000 in exchange for a non-interest bearing, unsecured promissory note.

At the First Extension Meeting, shareholders holding 16,775,137 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $186.7 million (or approximately $11.13 per share) was removed from the Trust Account to pay such holders, and 13,724,863 Public Shares remain outstanding. Following the First Extension Meeting, the Sponsor has (or its affiliates or designees have) deposited an aggregate of $1.0 million into the Trust Account to extend the Termination Date from July 18, 2025 to November 18, 2025 pursuant to the Second A&R Memorandum and Articles of Association.

BENEFICIAL OWNERSHIP OF SECURITIES

The following table sets forth information regarding the beneficial ownership of the Company’s Ordinary Shares as of the Record Date, based on information obtained from the persons named below, with respect to the beneficial ownership of the Company’s Ordinary Shares, by:

•

each person known by the Company to be the beneficial owner of more than 5% of the Company’s issued and outstanding Ordinary Shares;

•

each of the Company’s officers and directors; and

•

all the Company’s executive officers and directors as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if such person possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within sixty days.

In the table below, percentage ownership is based on 21,349,863 Ordinary Shares, consisting of (i) 13,724,863 Class A Ordinary Shares, (ii) 7,625,000 Class F Ordinary Shares and (iii) no Class B Ordinary Shares, issued and outstanding as of the Record Date. The table below does not reflect record or beneficial ownership of any Ordinary Shares issuable upon exercise of the warrants because these securities are not exercisable within 60 days of the Record Date.

Unless otherwise indicated, we believe that all persons named in the table have sole voting and investment power with respect to all Ordinary Shares beneficially owned by them.

HOUSEHOLDING INFORMATION

Unless the Company has received contrary instructions, the Company may send a single copy of this proxy statement to any household at which two or more shareholders reside if the Company believes the shareholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce the Company’s expenses. However, if shareholders prefer to receive multiple sets of the Company’s disclosure documents at the same address this year or in future years, the shareholders should follow the instructions described below. Similarly, if an address is shared with another shareholder and together both of the shareholders would like to receive only a single set of the Company’s disclosure documents, the shareholders should follow these instructions:

•

If the shares are registered in the name of the shareholder, the shareholder should contact us at our offices at Nabors Energy Transition Corp. II, 515 West Greens Road, Suite 1200, Houston, TX 77067, to inform us of his or her request; or

•

If a bank, broker or other nominee holds the shares, the shareholder should contact the bank, broker or other nominee directly.
