Explanation of Responses:

( 1 )On March 31, 2026, CoinShares PLC, a public company limited by shares organized under the laws of Jersey (the "Issuer"), consummated its previously announced business combination (the "Business Combination") pursuant to Business Combination Agreement, dated as of September 8, 2025, by and among the Company, CoinShares International Limited, a public company limited by shares organized under the laws of Jersey ("CSIL"), and the other parties thereto. Upon closing of the Business Combination, the reporting person acquired these securities in exchange for the reporting person's securities in CSIL pursuant to the terms and conditions of the Business Combination Agreement. In the Business Combination, each CSIL share became approximately 1.8237 ordinary shares of the issuer. ( 2 )Pursuant to a Master Securities Loan Agreement, the reporting person sold shares of CSIL across 13 separate tranches. The reporting person holds a European-style call option with respect to each tranche, exercisable only on the applicable maturity date (the "Maturity Date") set forth in column 6 of Table II for the amount set forth in column 2 of Table II. Under the Master Securities Loan Agreement, the call option automatically substituted the Ordinary Shares of the Issuer issued in the Business Combination in exchange for the CSIL shares subject to the call option. During the term of the options, the reporting person pays the counterparty interest at the rate of 3.75%, per annum. The Maturity Date for each tranche is three years after to the applicable Closing Date; provided, if the resulting Maturity Date would fall less than 30 days after the Maturity Date of the immediately preceding tranche, the Maturity Date is instead30 days after the Maturity Date of such preceding tranche.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
