Mountain Lake Acquisition Corp. II Commitments Disclosure

Note 7 — Commitments and Contingencies

Risks and Uncertainties

The Company’s ability to complete an initial Business Combination may be adversely affected by various factors, many of which are beyond the Company’s control. The Company’s ability to consummate an initial Business Combination could be impacted by, among other things, changes in laws or regulations, downturns in the financial markets or in economic conditions, inflation, fluctuations in interest rates, increases in tariffs, supply chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the military conflicts in Ukraine and the Middle East. The Company cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s ability to complete an initial Business Combination.

Registration Rights

The holders of the (i) Founder Shares, (ii) Private Placement Units (and their underlying securities) and (iii) Working Capital Units (and their underlying securities), if any, (iv) any Class A Ordinary Shares issuable upon conversion of the Founder Shares and (iv) any Class A Ordinary Shares held at the completion of the Initial Public Offering by the holders of the Founder Shares prior to the Initial Public Offering, have registration rights to require the Company to register a sale of any of the Company’s securities held by them and any other securities of the Company acquired by them prior to the consummation of or acquired prior to or in connection with the initial Business Combination pursuant to a registration rights agreement, dated January 29, 2026, by and between the Company and certain security holders. These holders are entitled to make up to three demands excluding short form demands and have piggyback registration rights. BTIG may only make a demand on one occasion and only during the five-year period beginning on January 26, 2026. In addition, BTIG may participate in a piggyback registration only during the seven-year period beginning on January 26, 2026. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the Underwriters a 45-day option from the date of the Initial Public Offering to purchase up to 4,698,000 additional Option Units to cover any over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions (the “Over-Allotment Option”). The Option Units issued in connection with the Over-Allotment Option are identical to the Public Units sold in the Initial Public Offering. On January 28, 2026, the Underwriters partially exercised their Over-Allotment Option in the amount of 4,680,000 Option Units as part of the closing of the Initial Public Offering. On March 11, 2026, the Underwriters forfeited the remaining unexercised balance of 18,000 Option Units.

The Underwriters were entitled to a cash underwriting discount of $0.20 per Unit sold in the Initial Public Offering, or $7,200,000 in the aggregate, paid on the closing of the Initial Public Offering. In addition, the Underwriters are entitled to a contingent, deferred fee of $0.35 per Unit, or $12,600,000 in the aggregate (the “Deferred Fee”). The Deferred Fee will become payable to the Underwriters from the amounts held in the Trust Account and will be released to the Underwriters only upon the consummation of an initial Business Combination, but (i) $0.15 per Public Unit of such $0.35 per Public Unit shall be due solely on amounts remaining in the Trust Account following all properly submitted shareholder redemptions in connection with the consummation of the initial Business Combination and (ii) $0.05 per Public Unit of such $0.35 per Public Unit shall be allocable by the Company to certain third parties that are members of Financial Industry Regulatory Authority, but that did not participate in the Initial Public Offering, that assist the Company in consummating its initial Business Combination.
