NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Rice Acquisition Corporation 3 is a blank check company incorporated as a Cayman Islands exempted company on June 6, 2025. As used herein, the “Company” refers to Rice Acquisition Corporation 3 and its subsidiary, Rice Acquisition Holdings 3 LLC, a Cayman Islands limited liability company (“Opco”), unless the context indicates otherwise. The Company was formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company has not selected any specific Business Combination target, and the Company has not, nor has anyone on its behalf, engaged in any substantive discussions, directly or indirectly, with any Business Combination target with respect to an initial Business Combination with the Company.

As of June 30, 2026, the Company had not commenced any operations. All activity for the period from June 6, 2025 (inception) through June 30, 2026 relates to the Company’s formation, the Initial Public Offering (as defined below) and, subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from a portion of the proceeds derived from the Initial Public Offering and the sale of the Private Placement Warrants (as defined below). The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on September 30, 2025. On October 2, 2025, the Company consummated the initial public offering (the “Initial Public Offering”) of 34,500,000 units (each, a “Unit” and collectively, the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), including 4,500,000 Units issued as a result of the full exercise by the underwriters of their over-allotment option, at $10.00 per Unit, generating gross proceeds of $345,000,000, which is discussed in Note 3. Each Unit consists of one Class A ordinary share and one-sixth of one redeemable warrant (each, a “Public Warrant”). Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment.

The Company’s sponsor is Rice Acquisition Sponsor 3 LLC, a Delaware limited liability company (the “Sponsor”). Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 10,650,000 private placement warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”), including 900,000 Private Placement Warrants issued as a result of the full exercise by the underwriters of their over-allotment option, at a price of $1.00 per Private Placement Warrant, or $10,650,000 in the aggregate, in a private placement to the Sponsor. Each Private Placement Warrant is exercisable to purchase one of the Company’s Class A ordinary shares.

Transaction costs amounted to $23,330,776, consisting of $6,900,000 of cash underwriting fee, $13,368,750 of maximum deferred underwriting fee, and $3,062,026 of other offering costs.

Following the closing of the Initial Public Offering, the Public Shareholders (as defined below) hold a direct economic equity ownership interest in the Company in the form of Class A ordinary shares, and an indirect ownership interest in Opco through the Company’s ownership of Class A units of Opco. By contrast, the Initial Shareholders (as defined below) own Founder Securities (as defined in Note 4) and Sponsor Securities (as defined in Note 4) which include direct economic interests in Opco in the form of Class A and Class B units of Opco and a corresponding non-economic voting equity interest in the Company in the form of Class B ordinary shares (see Note 4).

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (as defined below) (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-business combination company owns or acquires 50% or more of the voting securities of the Target (as defined below) or otherwise acquires a controlling interest in the Target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

Following the closing of the Initial Public Offering on October 2, 2025, an amount of $345,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units and the Private Placement Warrants was placed in a trust account (the “Trust Account”) located in the United States with Odyssey Transfer and Trust Company acting as trustee (the “Trustee”). The funds may (i) only be invested in U.S. “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, as determined by the Company, (ii) be held as uninvested cash or (iii) be held in an interest or non-interest bearing bank demand deposit account or other accounts at a bank, until the earlier of (a) the completion of a Business Combination or (b) the distribution of the Trust Account as described below.

The Company will provide the holders (the “Public Shareholders”) of the Public Shares with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting fee the Company will pay to the underwriters (as discussed in Note 5). The Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to its amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (the “SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transaction is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the holders of Founder Securities and Sponsor Securities prior to the Initial Public Offering, including the Company’s officers and directors to the extent they hold such securities (the “Initial Shareholders”), have agreed to vote their Founder Securities and Sponsor Securities and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Shareholders have agreed to waive their redemption rights with respect to their Founder Securities and Public Shares in connection with the completion of a Business Combination.

These Public Shares are recorded at redemption value and classified as temporary equity in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”).

If the Company is unable to complete a Business Combination within 24 months (or 27 months if the Sponsor exercises its three-month extension option) from the closing of the Initial Public Offering (the “Combination Period”) or if the Company’s board of directors approves an earlier liquidation, 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 and not previously released to the Company to pay taxes of the Company or Opco, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating 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 Company’s board of directors, liquidate and dissolve, subject in each case, to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the warrants, which will expire worthless if the Company fails to consummate an initial Business Combination within the Combination Period, or if the Company’s board of directors approves an earlier liquidation.

Pursuant to the Second Amended and Restated Limited Liability Agreement of Opco (the “Opco LLC Agreement”) and a letter agreement that the Sponsor, and the Company’s officers and directors have entered into with the Company, the Sponsor and the Company’s officers and directors have agreed (i) to waive their redemption rights with respect to their Founder Securities and Sponsor Securities, (ii) to waive their redemption rights with respect to their Founder Securities, Sponsor Securities and Public Shares in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association that would modify the substance or timing of its obligation to provide holders of the Company’s Class A ordinary shares the right to have their shares redeemed in connection with the Company’s initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete its initial Business Combination within the Combination Period, or if the Company’s board approves an earlier liquidation, (iii) that they will not be entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Securities or Sponsor Securities they hold if the Company fails to consummate an initial Business Combination within the Combination Period (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete its initial Business Combination within the Combination Period), and (iv) that, in certain circumstances, the Class B units of Opco will have more limited rights to current or liquidating distributions from the Company.

The underwriters have agreed to waive their rights to their deferred underwriting commission held in the Trust Account in the event the Company does not consummate an initial Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per-share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.
