Avalanche Treasury Corporation (the “Company”) was incorporated in Delaware on September 22, 2025 in connection with the transactions that culminated in the Business Combination with Mountain Lake Acquisition Corp. (“MLAC”), which closed on June 11, 2026. On October 1, 2025, the Company entered into a Business Combination Agreement (the “Agreement”) with Mountain Lake Acquisition Corp. (“SPAC”), Avalanche Treasury Company LLC, a Delaware limited liability company (“Treasury LLC”), Avalanche SPAC Merger Sub LLC (“SPAC Merger Sub”), Avalanche Company Merger Sub LLC (“Company Merger Sub,” and together with SPAC Merger Sub, the “Company Subsidiaries”), and Dragonfly Digital Management, LLC (the “Seller”), pursuant to which the transactions contemplated therein (collectively, the “Business Combination”) were consummated on June 11, 2026 (the “Closing Date”). Following the Business Combination and related recapitalization transactions, the Company became a publicly traded company and operates through Avalanche Treasury Company, LLC to hold and manage AVAX, conduct staking and validator operations, and support other Avalanche-related activities.

Pursuant to the Agreement, on the Closing Date, (i) SPAC Merger Sub merged with and into SPAC (the “SPAC Merger”), with SPAC continuing as the surviving entity and a wholly owned subsidiary of the Company, and (ii) Company Merger Sub merged with and into Avalanche Treasury Company LLC (the “Subsidiary Merger,” and together with the SPAC Merger, the “Mergers”), with Treasury LLC continuing as the surviving entity and a wholly owned subsidiary of the Company.

In connection with the Subsidiary Merger, each member of Treasury LLC other than the Seller received one share of the Company’s Class A common stock, par value $0.01 per share (“Class A Stock”), for each unit held immediately prior to the effective time of the Subsidiary Merger, and the Seller received one share of Class A Stock and one share of the Company’s Class B common stock, par value $0.01 per share (“Class B Stock”), for each unit it held. As a result of the consummation of the Business Combination, the Company became a publicly traded entity and Treasury LLC became its wholly owned subsidiary.

The Company is an operating company focused exclusively on business lines relating to Avalanche and AVAX, offering public-market investors a differentiated, capital-efficient means of gaining exposure to Avalanche and AVAX through (i) the targeted accumulation of AVAX; (ii) treasury management activities, including staking and other yield-generating strategies designed to increase AVAX per share over time; and (iii) broader ecosystem participation, including validator operations, Avalanche L1 activation, infrastructure services and other corporate development initiatives intended to expand the Company’s participation in the Avalanche ecosystem.
