Amendment Description This Amendment No. 1 to the Annual Report on Form 10-K of Bitwise Bitcoin ETF (the “Trust”) for the year ended December 31, 2025, as originally filed with the Securities and Exchange Commission on March 2, 2026 (the “Original Form 10-K”), is being filed solely to file the consent of KPMG LLP, the Trust’s independent registered public accounting firm (the “Consent”). Due to an administrative error, the Consent was inadvertently not included in the Original Form 10-K. In accordance with Rule 12b-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Amendment No. 1 includes new certifications required by Section 302 of the Sarbanes-Oxley Act of 2002, as amended, dated as of the filing date of this Amendment No. 1. Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K under the Exchange Act, paragraphs 3, 4 and 5 of the certifications have been omitted. Except as set forth in this Amendment No. 1, no other changes have been made to the Original Form 10-K. The Original Form 10-K has not been amended or updated to reflect events occurring after the filing date of the Original Form 10-K, except as specifically set forth in this Amendment No. 1. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Form 10-K.
