DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Mountain Lake Acquisition Corp. (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on June 14, 2024. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses that the Company has not yet identified (“Business Combination”). The Company may pursue an acquisition opportunity in any industry or geographic location. As of June 30, 2025, the Company has not commenced any operations. All activity for the period from June 14, 2024 (inception) through June 30, 2025, relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described 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 a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. 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 December 12, 2024. On December 16, 2024, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the shares of Class A ordinary shares included in the Units sold, the “Public Shares”), which includes the partial exercise by the underwriters of their over-allotment option in the amount of 2,000,000 Units, at $10.00 per Unit, generating gross proceeds of $230,000,000, which is described in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 805,000 private placement units (each, a “Private Placement Unit”) at a price of $10.00 per Private Placement Unit in a private placement to Mountain Lake Acquisition Sponsor LLC, a Delaware limited liability company (“Sponsor”), and BTIG, representative of the underwriters (“BTIG”), generating gross proceeds of $8,050,000, which is described in Note 4. Transaction costs amounted to $13,354,261, consisting of $4,600,000 of cash underwriting fee, $8,050,000 of deferred underwriting fee and $704,261 of other offering costs. The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering and the sale of Private Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding any deferred underwriters fees and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement in connection with the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target 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. Upon the closing of the Proposed Public Offering, management has agreed that an amount equal to at least $10.05 per Unit sold in the Proposed Public Offering, including the proceeds of the Private Placement Units, will be held in a trust account (“Trust Account”) with Continental Stock Transfer & Trust Company acting as trustee and invested 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, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below. Following the closing of the Initial Public Offering on December 16, 2024, an amount of $231,150,000 ($10.05 per Unit) from the net proceeds of the sale of the Units, and a portion of the net proceeds from the sale of the Private Placement Units, was placed in the Trust Account with Continental Stock Transfer & Trust Company acting as trustee. The funds will be held in cash, including in demand deposit accounts at a bank, or invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below. The Company will provide its holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem, regardless of whether they abstain, vote for, or against, a Business Combination, all or a portion of their Public Shares upon either (i) the completion of the initial Business Combination or an earlier redemption in connection with the commencement of the consummation of the initial Business Combination if the Company determines it is desirable to facilitate the completion of the initial Business Combination, (ii) the redemption of the Public Shares if the Company is unable to complete the initial Business Combination within the Combination Period (as defined below), subject to applicable law, or (iii) the redemption of the Public Shares properly submitted in connection with a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination within the Combination Period or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity. All of the Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with the liquidation, if there is a shareholder vote or tender offer in connection with the initial Business Combination and in connection with certain amendments to the Amended and Restated Memorandum and Articles of Association (the “Amended and Restated Memorandum and Articles of Association”). The Public Shares were recorded at redemption value and classified as temporary equity at the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” 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 the Founder Shares prior to the Initial Public Offering (the “Initial Shareholders”) have agreed to vote their Founder Shares (as defined in Note 5) 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 Shares and Public Shares in connection with the completion of a Business Combination. In addition, the Company has agreed not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor. Notwithstanding the foregoing, the Company’s Amended and Restated Memorandum and Articles of Association provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company. The Sponsor, executive officers, and directors have agreed, pursuant to a letter agreement, that they will not propose any amendment to the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares upon approval of any such amendment 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 (which interest shall be net of taxes payable), divided by the number of then outstanding Public Shares. If the Company is unable to complete a Business Combination within 18 months from the closing of the Initial Public Offering or during any extended time that the Company has to consummate a Business Combination beyond 18 months as a result of a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association (the “Combination Period”), the Company will, 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 (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any) subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. In such event, the rights will expire and be worthless. In connection with the redemption of 100% of the Company’s outstanding Public Shares for a portion of the funds held in the Trust Account, each holder will receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the fund held in the Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses). The Initial Shareholders have agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholders should acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a 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 Company’s 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 $10.05 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.05 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 $10.05 per 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 prospective target business who 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”). 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. 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 vendors, service providers (except the Company’s independent registered public accounting firm), 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. *Liquidity, Capital Resources and Going Concern* As of June 30, 2025, the Company had $1,160,883 in cash and a working capital surplus of $1,012,122. Further, the Company has incurred and expects to continue to incur significant costs in pursuit of its financing and acquisition plans. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” codified in FASB ASC Topic 205-40, “Presentation of Financial Statements—Going Concern”, as of June 30, 2025, the Company has sufficient funds for the working capital needs of the Company until a minimum of one year from the date of issuance of these condensed financial statements. The Company cannot ensure that its plans to raise capital or to consummate an initial Business Combination will be successful. In addition, Management has determined that if the Company is unable to complete an initial Business Combination within the Combination Period, then the Company will cease all operations except for the purpose of liquidating. This condition raises substantial doubt about the Company’s ability to continue as a going concern. Management plans to consummate an initial Business Combination prior to the mandatory liquidation date. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after June 16, 2026.
