Item 1.01 Entry into a Material Definitive

Agreement.

On July 7, 2026, CO2 Energy

Transition, LLC, a Delaware limited liability company (the “Sponsor”), the sponsor of CO2 Energy Transition Corp. (the

“Company”), deposited $229,700 (the “Second Extension Payment”) into the Company’s trust account,

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 “Business Combination”), for an additional

one month. Following the adoption of such resolution and deposit of the Second Extension Payment into the trust account, the Company has

until July 22, 2026, to complete its initial Business Combination (the “Extension”).

connection with the Extension, and to evidence the Second Extension Payment, on July 7, 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 “Second Extension Note”).

Amounts owed under the Second

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 “Maturity

Date”), 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 (“Second Extension Note Units”),

at a conversion price of $10.00 per Second 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 (“IPO”),

and each eight rights entitling the holder to receive one share of common stock upon completion of the Business Combination. The Second

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 “Registrable Securities” 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 Second Extension Note does not purport to be complete and is qualified in its entirety by the terms and conditions of the Second

Extension Note, a copy of which is attached hereto as Exhibit 10.1 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 Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.03 to

the extent required herein. The maturity date of the Second 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 Second 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 Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02 to

the extent required herein. The units, shares, warrants and rights that may be issued pursuant to the Second Extension Note (the “Second

Extension Note Securities”) will not be registered under the Securities Act of 1933, as amended (the “Securities Act”),

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 Second Extension Note Units (the “Second Extension Note Warrants”) 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 Second 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 Second

Extension Note Warrants will be identical to the warrants included in the units sold in the Company’s initial public offering, except

that the Second Extension Note Warrants and the common stock issuable upon the exercise of the Second 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 Second 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 Second Extension Note Warrants are held by someone other than the

initial purchasers or their permitted transferees, the Second 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 Second Extension Note

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

Item 8.01 Other Events

July 7, 2026, the Company mailed its proxy materials to stockholders in connection with its upcoming Annual Meeting of Stockholders at

which stockholders will consider the following proposals: (i) a proposal to extend the deadline by which it must complete an initial business

combination on a month-to-month basis to June 22, 2027 provided that for each monthly extension it deposits the lesser of $50,000 or $0.03

per Public Share that remains outstanding, (ii) a proposal to amend the Investment Management Trust Agreement to permit the extension,

(iii) the election of five members of the Board of Directors, (iv) the ratification of the appointment of WithumSmith+Brown PC as the

Company’s independent registered public accounting firm for the year ended December 31, 2026, and (v) the approval of an adjournment

of the Annual Meeting if the Chairman deems necessary.

ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY

CONVERTIBLE PROMISSORY NOTE

July 7, 2026

FOR VALUE RECEIVED and subject

to the terms and conditions set forth herein, CO2 Energy Transition Corp., a Delaware corporation (the “Maker”),

promises to pay to CO2 Energy Transition, LLC, a Delaware limited liability company, or its registered assigns or successors

in interest (the “Payee”), the Total Principal Amount (as defined below), in lawful money of the United States

available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice

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 “A&R Certificate”), 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).

8. Conversion.

(a) Optional Conversion.

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

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

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.

(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

of the Maker or the Payee, and the Maker shall be forever released from all its obligations and liabilities under this Note.

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

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.

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

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.

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.

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.

15. Trust Waiver. Notwithstanding

anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”)

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.

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 1st Extension

Page 5 of 7

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.

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. Each

Note thus transferred shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with the

Securities Act of 1933, as amended (the “Securities Act”), unless in the opinion of counsel for the Maker such

legend is not required in order to ensure compliance with the Securities Act. The Maker may issue stop transfer instructions to its transfer

agent in connection with such restrictions. Subject to the foregoing, transfers of this Note shall be registered upon registration on

the books maintained for such purpose by or on behalf of the Maker. Prior to presentation of this Note for registration of transfer, the

Maker shall treat the registered holder hereof as the owner and holder of this Note for the purpose of receiving all payments of principal

hereon and for all other purposes whatsoever, whether or not this Note shall be overdue and the Maker shall not be affected by notice

to the contrary.

19. Acknowledgment.

The Payee is an “accredited investor” as such term is defined in Rule 501 of the Securities Act and is acquiring

this Note for investment for its own account, not as a nominee or agent, and not with a view to, or for resale in connection with, any

distribution thereof in violation of applicable securities laws. The Payee understands that the acquisition of this Note involves substantial

risk. The Payee has experience as an investor in securities of companies and acknowledges that it is able to fend for itself, can bear

the economic risk of its investment in this Note, and has such knowledge and experience in financial and business matters that it is capable

of evaluating the merits and risks of this investment in this Note and protecting its own interests in connection with this investment.
