Risk factors and legal proceedings

The risks Mountain Lake Acquisition Corp. names in Item 1A of its 10-K filed Feb 20, 2026: 3 risks under these headings, as written.⁴

• We are dependent upon our executive officers and directors and their loss, or a reduction in the amount of time they can dedicate to our initial business combination, could adversely affect our ability to operate.
• We may issue additional Class A Ordinary Shares or preference shares to complete our initial business combination or under an employee incentive plan after completion of our initial business combination. We may also issue Class A Ordinary Shares upon the conversion of the founder shares at a ratio greater than one-to-one at the time of our initial business combination as a result of the anti-dilution provisions contained in our amended and restated memorandum and articles of association. Any such issuances would dilute the interest of our shareholders and likely present other risks.
• We may amend the terms of the rights in a manner that may be adverse to holders of public rights with the approval by the holders of at least 50% of the then outstanding public rights.

Legal proceedings

There is no material litigation, arbitration or governmental proceeding currently pending against us or any members of our management team in their capacity as such.
