Mountain Lake Acquisition Business Summary

Mountain Lake Acquisition Corp. (MLAC) is a special purpose acquisition company (SPAC) that currently generates revenue through interest income on its trust account, which holds approximately $231 million in capital. The company is in the final stages of a definitive business combination with Avalanche Treasury Co. (AVAT), a transaction valued at over $675 million and expected to close in Q1 2026. Post-merger, the business model will transition to a digital asset treasury management firm focused on the Avalanche (AVAX) ecosystem, deriving revenue from active treasury yield, strategic protocol investments, and validator infrastructure operations. MLAC competes directly with other specialized blank check vehicles such as Armada Acquisition II, SIM Acquisition I, and Fifth Era Acquisition Corp I; it distinguishes itself as a high-conviction vehicle for institutional blockchain exposure through an exclusive strategic relationship with the Avalanche Foundation. The leadership team is anchored by Executive Chairman and CEO Paul Jaron Grinberg and CFO/President Douglas Horlick, both of whom previously led Social Leverage Acquisition Corp I (SLAC). Grinberg brings extensive experience from his tenure as a senior advisor at Blenheim Chalcot and his leadership at Axos Financial, while Horlick’s pedigree includes senior securities roles at Goldman Sachs, Bank of America, and Citigroup. The company’s board includes notable industry veterans such as Jeffrey Lager, a former partner at Capital Group, and Michael Marquez. MLAC is supported by a high-profile investor base including the Avalanche Foundation, VanEck, Dragonfly, Galaxy Digital, and Pantera Capital, positioning the entity as a foundational institutional partner within the digital asset landscape.
