EXPLANATORY NOTE

This Amendment No.1 on Form 10-K/A (this “Amendment”) amends and supplements the Annual Report on Form 10-K of Circle Internet Group, Inc. (the “Company”) for the year ended December 31, 2025, originally filed with the Securities and Exchange Commission (the “SEC”) on March 9, 2026 (the “Original Form 10-K”), solely to provide the separate audited financial statements of the Circle Reserve Fund (the “Fund”), a money market fund managed by BlackRock Advisors, LLC, as required by Rule 3-09 of Regulation S-X under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The audited financial statements of the Fund were not available at the time of the filing of the Original Form 10-K because the Fund has a fiscal year end of April 30. Accordingly, this Amendment hereby amends Part IV, Item 15 of the Original Form 10-K solely to include the audited financial statements of the Fund as of and for the year ended April 30, 2026, together with the related report of Deloitte & Touche LLP, the Fund’s independent registered public accounting firm. The consent of Deloitte & Touche LLP is hereby included as Exhibit 23.2 of this Amendment. In addition, in accordance with applicable rules and regulations promulgated by the SEC, this Amendment includes updated certifications from our Chief Executive Officer and Chief Financial Officer as Exhibits 31.1, 31.2, 32.1 and 32.2.

Except as described above, this Amendment does not amend, update, or restate any other information or disclosure included in the Original Form 10-K, and the Company has not updated disclosures contained therein to reflect any events that occurred at a date subsequent to the filing of the Original Form 10-K, except as expressly noted herein. This Amendment should be read in conjunction with the Original Form 10-K and the Company's other filings with the SEC. Without limiting the foregoing, this Amendment does not modify or update in any way the disclosures made in the Original Form 10-K affected by subsequent events, and does not reflect events occurring after the filing of the Original Form 10-K.
