**Item 1.01 Entry into a Material Definitive Agreement.**

On May 18, 2026, CO2 Energy Transition, LLC, a Delaware limited liability company (the "<u>Sponsor</u>"), the sponsor of CO2 Energy Transition Corp. (the "<u>Company</u>"), deposited $229,700 (the "<u>First Extension Payment</u>") into the Company's trust account, following the adoption of a resolution by the Board of Directors of the Company (the "<u>Board</u>"), to extend the period of time for the Company to consummate an initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the "<u>Business Combination</u>"), for an additional one month. Following the adoption of such resolution and deposit of the First Extension Payment into the trust account, the Company has until June 22, 2026, to complete its initial Business Combination (the "<u>Extension</u>").

Pursuant to the Company's Amended & Restated Certificate of Incorporation (the "<u>Certificate of Incorporation</u>"), the Company had until May 22, 2026, or 18 months from the consummation of its initial public offering to consummate its initial Business Combination, provided that pursuant to the Certificate of Incorporation, the Company may, but is not obligated to, extend the period of time to consummate an initial Business Combination up to six times (i.e., up to 24 months from the initial public offering) by an additional one month each, if the Sponsor and/or its designees deposit into the trust account $229,700 ($0.0333 per share subject to redemption) for each one month extension.

If the Board of Directors anticipates that the Company may not be able to consummate an initial Business Combination by June 22, 2026, the Board of Directors, by resolution, may further extend the period of time to consummate an initial Business Combination, up to five additional times, each by an additional one month (which extensions as discussed above are subject to additional extension payments). In the event the Company's initial Business Combination is not completed by the June 22, 2026 deadline, the Company expects to further extend the date by which the Company is required to complete its initial Business Combination.

In connection with the Extension, and to evidence the First Extension Payment, on May 18, 2026, the Company entered into a convertible promissory note dated as of the same date with its Sponsor in the principal amount of $229,700 (the "<u>First Extension Note</u>").

Amounts owed under the First Extension Note do not accrue interest and are payable on the earlier of: (i) the effective date of the consummation of the Company's initial Business Combination; or (ii) the date that the winding up of the Company is effective (such date, as applicable, the "<u>Maturity Date</u>"), unless accelerated upon the occurrence of an Event of Default (as defined in the First Extension Note).

Amounts outstanding under the First Extension Note, are convertible, at the option of the Sponsor, into units of the Company ("<u>First Extension Note Units</u>"), at a conversion price of $10.00 per First Extension Note Unit, with each unit consisting of one share of Company common stock, one warrant, and one right, with each warrant entitling the holder thereof to purchase one share of common stock at $11.50 per share, subject to adjustment as provided in the Company's Registration Statement on Form S-1 filed in connection with its initial public offering ("<u>IPO</u>"), and each eight rights entitling the holder to receive one share of common stock upon completion of the Business Combination. The First Extension Note Units will be identical to the private placement units issued to the Sponsor at the time of the Company's IPO.

The shares, warrants and rights constitute "<u>Registrable Securities</u>" pursuant to that certain Registration Rights Agreement, dated November 20, 2024, by and among the Company, Sponsor and certain other security holders named therein.

The foregoing description of the First Extension Note does not purport to be complete and is qualified in its entirety by the terms and conditions of the First Extension Note, a copy of which is attached hereto as <u>Exhibit 10.1</u> and incorporated herein by reference.

**Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.**

The information disclosed under <u>Item 1.01</u> of this Current Report on Form 8-K is incorporated by reference into this <u>Item 2.03</u> to the extent required herein. The maturity date of the First Extension Note may be accelerated upon the occurrence of an Event of Default (as defined therein). The Company may not prepay any outstanding principal amount under the First Extension Note in whole or in part at any time without the advance written consent of the Sponsor, which may be withheld by the Sponsor for any reason or for no reason.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information disclosed under <u>Item 1.01</u> of this Current Report on Form 8-K is incorporated by reference into this <u>Item 3.02</u> to the extent required herein. The units, shares, warrants and rights that may be issued pursuant to the First Extension Note (the "<u>First Extension Note Securities</u>") will not be registered under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"), and will be issued in reliance on the exemption from registration requirements thereof provided by Section 4(a)(2) of the Securities Act. Each warrant which forms a part of the First Extension Note Units (the "<u>First Extension Note Warrants</u>") will entitle the holder thereof to purchase one share of common stock of the Company at an exercise price of $11.50 per share, subject to certain adjustments. The First Extension Note Warrants will become exercisable on the later of (i) 30 days after the completion of the Business Combination and (ii) 12 months from the closing of the Company's IPO, subject to certain conditions and exceptions. Such First Extension Note Warrants will be identical to the warrants included in the units sold in the Company's initial public offering, except that the First Extension Note Warrants and the common stock issuable upon the exercise of the First Extension Note Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the First Extension Note Warrants will be exercisable on a cashless basis and will be non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the First Extension Note Warrants are held by someone other than the initial purchasers or their permitted transferees, the First Extension Note Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the public warrants sold in the IPO.

The First Extension Note is convertible into a maximum of 22,970 First Extension Units.

**Item 7.01 Regulation FD Disclosure.**

The Company continues to make progress towards completing an initial Business Combination and hopes to be in a position to disclose more details regarding such progress in the near future.

FOR VALUE RECEIVED and subject to the terms and conditions set forth herein, CO2 Energy Transition Corp., a Delaware corporation (the "**<u>Maker</u>**"), promises to pay to CO2 Energy Transition, LLC, a Delaware limited liability company, or its registered assigns or successors in interest (the "**<u>Payee</u>**"), the Total Principal Amount (as defined below), in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note. This Convertible Promissory Note represents amounts loaned to the Maker by the Payee in order to pay the first of six one (1) month extension payments available to be made pursuant to Article Fifth, Section E, of the Maker's Amended and Restated Certificate of Incorporation (the "**<u>A&R Certificate</u>**"), which, provides that if the Maker anticipates that it may not be able to consummate a Business Combination (as defined in the A&R Certificate) within 18 months, the Maker may extend the period of time to consummate a Business Combination up to six times, each by an additional one month (for a total of up to 24 months to complete a business combination).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1. Principal**. The principal balance of this Note of $229,700 (the "**<u>Total Principal Amount</u>**"), shall be payable on the earlier of: (i) the effective date of the consummation of the Maker's initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the "**<u>Business Combination</u>**") or (ii) the date that the winding up of the Maker is effective (such date, the "**<u>Maturity Date</u>**"), unless accelerated upon the occurrence of an Event of Default (as defined below). Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder. The Payee understands that if a Business Combination is not consummated, this Note will be repaid solely to the extent that the Maker has funds available to it outside of its trust account established in connection with its initial public offering of its securities (the "**<u>Trust Account</u>**" and such offering, the "**<u>IPO</u>**"), and that all other amounts will be contributed to capital, forfeited, eliminated or otherwise forgiven or eliminated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7. Remedies**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Upon the occurrence of an Event of Default specified in Section 6(a) hereof, the Payee may, by written notice to the Maker, declare this Note to be due immediately and payable, whereupon the unpaid Total Principal Amount of this Note, and all other amounts payable hereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon the occurrence of an Event of Default specified in Section 6(b) and Section 6(c) hereof, the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of the Payee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**8. Conversion**.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Optional Conversion</u>. Upon consummation of a Business Combination, the Payee shall have the option, but not the obligation, to convert up to the Total Principal Amount of this Note, in whole or in part at the option of the Payee, into units of the Maker each consisting of one share of Maker's common stock, one warrant, and one right, with each warrant entitling the holder thereof to purchase one share of common stock at $11.50 per share, subject to adjustment as provided in the Maker's Registration Statement on Form S-1 filed in connection with the IPO, and each eight rights entitling the holder to receive one share of common stock upon completion of the Business Combination (each, a "**<u>Unit</u>**"), at a conversion price of $10.00 per Unit. The Units shall be identical to the private placement units issued to the Sponsor at the time of the Maker's IPO (the "**<u>Private Placement Units</u>**"). As promptly as reasonably practicable after notice by the Payee to the Maker to convert the principal balance of this Note, in whole or in part, into Private Placement Units, which notice, if given, must be given at least five business days prior to the consummation of the Business Combination, and after the Payee's surrender of this Note, the Maker shall have issued and delivered to the Payee, without any charge to Payee, a share certificate or certificates (issued in the name(s) requested by the Payee), or shall have made appropriate book- entry notation on the books and records of the Maker, in each case for the number of Private Placement Units of the Maker issuable upon the conversion of this Note. The conversion shall be deemed to have been made immediately prior to the close of business on the date of the surrender of this Note and the person or persons entitled to receive the Private Placement Units upon such conversion shall be treated for all purposes as the record holder or holders of such Private Placement Units as of such date. Each such newly issued Private Placement Share shall include restricted legends that contemplates the same restrictions as the Private Placement Units that were issued in connection with the IPO.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Before this Note may be converted under Section 8(a), the Payee shall surrender this Note, duly endorsed, at the office of the Maker and shall state therein the amount of the unpaid principal balance of this Note to be converted and the name or names in which the certificates for Private Placement Units are to be issued (or the book-entries to be made to reflect ownership of such Private Placement Units with the Maker's transfer agent). The conversion shall be deemed to have been made immediately prior to the close of business on the date of the surrender of this Note and the person or persons entitled to receive the Private Placement Units upon such conversion shall be treated for all purposes as the record holder or holders of such Private Placement Units as of such date. Each such newly issued Private Placement Unit shall include a restricted legend that contemplates the same restrictions as the Private Placement Units. The shares of Maker's common stock forming part of the Units, the shares of Maker's common stock issuable in connection with the rights forming part of the Units, and the shares of common stock issuable upon exercise of the warrants forming part of the Units shall constitute "Registrable Securities" pursuant to that certain Registration Rights Agreement, dated November 20, 2024, among the Maker, Payee and certain other security holders named therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Fractional Shares; Effect of Conversion</u>. No fractional Private Placement Units shall be issued upon conversion of this Note and the number of Private Placement Units deliverable will be rounded to the nearest whole number of Private Placement Units, with one-half (0.5) or more of a Private Placement Share being rounded upward. Upon conversion of this Note in full, this Note shall be cancelled and void without further action of the Maker or the Payee, and the Maker shall be forever released from all its obligations and liabilities under this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**9. Covenants of the Maker**. The Maker covenants that any Private Placement Units issuable upon conversion of the Note, when so issued, will be validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issuance thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**10. Waivers**. The Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor, protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by the Payee under the terms of this Note, and all benefits that might accrue to the Maker by virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and the Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by the Payee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**11. Unconditional Liability**. The Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by the Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by the Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to the Maker or affecting the Maker's liability hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**12. Notices**. All notices, statements or other documents which are required or contemplated by this Note shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party or (iii) by electronic mail, to the electronic mail address most recently provided to such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day following receipt of written confirmation, if sent by facsimile or electronic transmission, one business day after delivery to an overnight courier service or five days after mailing if sent by mail.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**13. Construction**. THIS NOTE SHALL BE GOVERNED AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**14. Severability**. Any provision contained in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**15. Trust Waiver**. Notwithstanding anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind ("**<u>Claim</u>**") in or to any monies in, or any distribution of or from, the Trust Account, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever. The Payee hereby agrees not to make any Claim against the Trust Account (including any distributions therefrom), regardless of whether such Claim arises as a result of, in connection with or relating in any way to, this Note, or any other matter, and regardless of whether such Claim arises based on contract, tort, equity or any other theory of legal liability. To the extent the Payee commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to the Maker (including this Note), which proceeding seeks, in whole or in part, monetary relief against the Maker, the Payee hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such Claim shall not permit the Maker (or any person claiming on its behalf or in lieu of it) to have any Claim against the Trust Account (including any distributions therefrom) or any amounts contained therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**16. Amendment; Waiver**. Any amendment hereto or waiver of any provision hereof may be made with, and only with, the written consent of the Maker and the Payee.

Convertible Promissory Note 1<sup>st</sup> Extension<br> Page 5 of 7

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**17. Assignment**. No assignment or transfer of this Note or any rights or obligations hereunder may be made by any party hereto without the prior written consent of the other party hereto and any attempted assignment without the required consent shall be void.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**18. Transfer of this Note or Securities Issuable on Conversion**. Prior to an Event of Default, neither this Note nor any rights hereunder may be assigned, conveyed or transferred, in whole or in part, without the Maker's prior written consent, which the Maker may withhold in its sole discretion; *provided*, that (i) the Payee may make an assignment or transfer of this Note to any of its affiliates, in which case the requirements in this clause (i) shall not apply, Payee shall deliver to Maker, a written opinion reasonably satisfactory to the Maker in form and substance from counsel reasonably satisfactory to the Maker to the effect that such sale or other distribution may be effected without registration or qualification under any U.S. federal or state law then in effect, and (ii) Payee shall deliver to Maker, a written undertaking executed by the desired transferee reasonably satisfactory to the Maker in form and substance agreeing to be bound by the restrictions on transfer contained herein. Upon receiving such written notice, reasonably satisfactory opinion, or other evidence, and such written acknowledgement, the Maker, as promptly as practicable, shall notify the Payee that the Payee may sell or otherwise dispose of this Note or such securities, all in accordance with the terms of the note delivered to the Maker. If a determination has been made pursuant to this Section 18 that the opinion of counsel for the Payee, or other evidence, or the written acknowledgment from the desired transferee, is not reasonably satisfactory to the Maker, the Maker shall so notify the Payee promptly after such determination has been made.
