Reworded paragraphs (7)

Previous wording

The Trust’s investment objective is to seek to track the performance of bitcoin, as measured by the performance of the Pricing Benchmark, adjusted for the Trust’s expenses and other liabilities. CF Benchmarks Ltd. is the Pricing Benchmark Provider. The Pricing Benchmark is designed to reflect the performance of bitcoin in U.S. dollars. In seeking to achieve its investment objective, the Trust holds bitcoin at its Custodians and the Administrator values the Shares daily based on the Pricing Benchmark. The Trust is a passive investment vehicle and is not a leveraged product. The Sponsor does not actively manage the bitcoin held by the Trust. On June 30, 2026, the Sponsor provided notice to the Pricing Benchmark Provider of the termination, effective August 31, 2026, of the licensing agreement between the Sponsor and the Pricing Benchmark Provider relating to the use of the Pricing Benchmark. The Sponsor intends to enter into a licensing agreement with FTSE on or about August 24, 2026, whereby FTSE will provide each of the Sponsor, the Trust, and their affiliates a non-exclusive, non-transferable, non-sub-licensable, worldwide license to access, view and use FTSE index data to develop, create, calculate, settle, maintain or support and market the Trust.

In seeking to achieve its investment objective, the Trust holds bitcoin and the Administrator values the Shares daily based on the Pricing Benchmark. The Sponsor does not actively manage the bitcoin held by the Trust. Prior to August 27, 2026, the Trust used the Prior Pricing Benchmark. On August 20, 2026, the Sponsor entered into a licensing agreement between the Sponsor and the Pricing Benchmark Provider relating to the use of the Pricing Benchmark and on August 27, 2026, the Trust began valuing its Shares and calculating its net asset value by reference to the Pricing Benchmark. Accordingly, the change in pricing benchmark provider had no material impact on the Trust's net asset value, the fair value measurement of the Trust's bitcoin, or the Trust's results of operations, and does not represent a change in accounting principle. The change was applied prospectively from the date the successor benchmark became effective.
