Description of Organization and Business Operations	1. Description of Organization and Business Operations CoinShares PLC f/k/a Odysseus Holdings Limited (“Holdco”) is a Bailiwick of Jersey, Channel Islands corporation, registered in Jersey, Channel Islands on August 29, 2025 (inception) and was the surviving company in connection with a business combination (as described below in Note 5, “Business Combination Agreement”). Holdco has no prior operating activities. Holdco was formed solely for the purpose of effectuating the business combination, and it does not own any material assets or conduct any business activities other than activities incidental to effectuating the business combination. In addition, Odysseus (Cayman) Limited, a Cayman Islands exempted company (“SPAC Merger Sub”) was formed on August 25, 2025, and is a wholly owned subsidiary of Holdco since incorporation. As of the reporting date, SPAC Merger Sub has no operations. Liquidity As of December 31, 2025, Holdco had cash of $30,422. Holdco recorded a net loss for the period from August 29, 2025 (Inception) to December 31, 2025 of $151,410. As of December 31, 2025, the Holdco’s total liabilities were $61,832. Holdco is a non-revenue generating holding company which was solely created to be the surviving company in connection with the Business Combination Agreement (as further described in Note 5). Prior to the consummation of the business combination, there was a risk that it would not be completed, and the Holdco would lack liquidity to sustain operations for significant costs associated with the merger which include, but are not limited to formation costs, filing costs, and legal costs. That risk was alleviated as Holdco has since completed the closing of the Business Combination at which time it obtained access to proceeds from the Trust Account, PIPE Investment and the operations of CoinShares, as further discussed in Note 5 and Note 7, for general working capital purposes.
