Circle Internet Group, Inc.

Item 1.01. Entry into a Material Definitive Agreement. Share Purchase Agreement On September 4, 2026, Circle Internet Group, Inc., a Delaware corporation (“Circle” or the “Company”), entered into a Share Purchase Agreement (the “Share Purchase Agreement” and the transactions set forth in the Share Purchase Agreement, the “Transactions”) by and among Taurus Acquisition Inc., a Delaware corporation and an indirect wholly owned subsidiary of Circle (“Purchaser”), each of the persons identified as a seller on the signature pages thereto (together with any person who subsequently executes a joinder as a seller, the “Sellers”), Tazapay Pte. Ltd., a private company incorporated under the laws of Singapore (the “Target Company”), Fortis Advisors LLC, in its capacity as sellers’ representative (the “Sellers’ Representative”), and, solely for certain purposes identified in the Share Purchase Agreement, Circle in its capacity as guarantor (the “Guarantor”). Pursuant to the Share Purchase Agreement, and subject to the satisfaction or waiver of the closing conditions described below, Purchaser will purchase and acquire from the Sellers all of the issued and outstanding shares of the Target Company not already held by Purchaser or its affiliates. Purchase Consideration The aggregate consideration to be paid by Purchaser in the Transaction (the “Aggregate Consideration”) will be a number of shares of Circle Class A common stock, par value $0.0001 per share (“Circle Common Stock”), equal to $400,000,000 (as adjusted to account for unpaid indebtedness, Target Company transaction expenses and cash held by the Target Company and its subsidiaries), divided by the volume-weighted average closing price per share of Circle Common Stock over the 20 consecutive trading days ending on and including the trading day immediately preceding the day on which the Transactions close (the “Closing Date”), rounded down to the nearest whole share (the “Closing Stock Price”). The aggregate consideration payable at the closing of the Transactions will be reduced by (i) shares representing five percent of the Aggregate Consideration to serve as recourse for certain indemnification obligations (the “Indemnity Holdback Shares”) and (ii) shares representing three percent of the Aggregate Consideration to serve as additional recourse for certain additional indemnification obligations (the “Indemnity Additional Holdback Shares”). If any such shares are not used to provide recovery for certain damages suffered by Purchaser, they will be released to the Sellers on a pro rata basis. Indemnity Holdback Shares The number of Indemnity Holdback Shares is calculated by dividing the indemnity holdback amount by the Closing Stock Price, rounded to the nearest whole share. The Indemnity Holdback Shares are to be retained by Purchaser in an indemnity holdback reserve and serve as the primary source of recovery for certain indemnification claims. The Sellers have no voting or economic rights in such shares until released. The Indemnity Holdback Shares are to be released in three installments, valued in each case using the volume-weighted average closing price per share of Circle Common Stock as reported on the New York Stock Exchange (NYSE) for the 20 consecutive trading days ending on (and including) the trading day immediately preceding the applicable release date: one-third of the Indemnity Holdback Shares on each of the six-month anniversary of the Closing Date and the 12-month anniversary of the Closing Date, and the remaining balance on the 18-month anniversary of the Closing Date, in each case subject to reduction for pending or unsatisfied claims. Indemnity Additional Holdback Shares The number of Indemnity Additional Holdback Shares is calculated by dividing the indemnity additional holdback amount by the Closing Stock Price, rounded to the nearest whole share. The Indemnity Additional Holdback Shares are to be retained by Purchaser in an indemnity additional holdback reserve and serve as the primary source of recovery for certain additional indemnification claims. The Sellers have no voting or economic rights in such shares until released. The Indemnity Additional Holdback Shares are to be released in four installments, valued in each case using the volume-weighted average closing price per share of Circle Common Stock as reported on the New York Stock Exchange (NYSE) for the 20 consecutive trading days ending on (and including) the trading day immediately preceding the applicable release date: one-fourth of the Indemnity Additional Holdback Shares on each of the 12-month anniversary of the Closing Date, the 24-month anniversary of the Closing Date, the 36-month anniversary of the Closing Date, and the remaining balance on the 48-month anniversary of the Closing Date, in each case subject to reduction for pending or unsatisfied claims. Treatment of Equity Awards At or prior to the Closing, all outstanding Target Company equity awards (“Equity Awards”), whether vested or unvested, will be cancelled and converted into the applicable portion of the Aggregate Consideration in the form of restricted shares of Circle Common Stock, subject to the terms of the applicable restricted stock agreements. Each holder of Equity Awards (and each Seller who is also a member of Target Company management) will enter into a restricted stock agreement prior to or at the Closing. Representations and Warranties The Share Purchase Agreement contains customary representations and warranties from the Sellers, the Target Company, Purchaser and the Guarantor, including as to organization, capitalization and title to shares, authority and enforceability, financial statements, litigation, material contracts, tax matters, employee benefits, intellectual property and data security, and compliance with laws and licenses and permits (including payment services, money transmission, stablecoin activities, anti-money laundering, anti-bribery, sanctions and trade controls). Survival of Representations and Warranties; Indemnification The representations and warranties of the Sellers, the Target Company and the Equity Award Holders survive for specified periods following the Closing. The Share Purchase Agreement contains certain indemnification provisions subject to specified limitations, including a basket, caps and exclusive remedy provisions. Representations and Warranties Insurance Concurrently with the execution and delivery of the Share Purchase Agreement, Purchaser entered into a binder agreement with respect to a buyer-side representations and warranties insurance policy (the “RWI Policy”). The RWI Policy is generally the exclusive source of recovery for claims for breaches of representations and warranties, except in cases of fraud and for other indemnification obligations specifically identified in the Share Purchase Agreement, including items not otherwise covered by the RWI Policy and certain other specifically identified indemnities. Interim Operating Covenants During the period from the date of the Share Purchase Agreement until the earlier of the Closing or the termination of the Share Purchase Agreement, the Target Company has agreed to customary interim operating covenants, including conducting its business in the ordinary course and not taking certain actions without Purchaser’s consent. Regulatory and Efforts Covenants The parties have agreed to use reasonable efforts to consummate the Transactions as promptly as practicable and to cooperate in making any required regulatory filings and obtaining applicable consents. Employee Benefits Covenants; Incentive RSUs Following the closing of the Transactions, Purchaser will grant awards of restricted stock units in respect of Circle Common Stock having an aggregate grant date fair value of $25,000,000 (the “Incentive RSUs”) to agreed employees of the Target Company and its subsidiaries. Each Incentive RSU award will vest in eight equal quarterly installments, beginning on the standard quarterly vesting date closest to the date that is 27 months following the Closing Date. Conditions to Closing The obligations of Purchaser and the Sellers to consummate the Transactions are subject to customary closing conditions, including filings with or the receipt of required approvals from certain regulators and related consents, the absence of laws or orders prohibiting the Transactions, the accuracy of the parties’ representations and warranties (subject to applicable materiality standards), compliance with their respective covenants, the absence of a material adverse effect, no less than 75% of certain identified employees remaining employed at the Target Company, as well the continued employment of certain members of senior management, completion of certain regulatory matters, effectiveness of the shelf registration statement, and delivery of specified closing deliverables. Termination The Share Purchase Agreement contains customary termination rights, including termination: (i) by mutual written consent; and (ii) by either party if the Closing has not occurred by the initial nine-month outside date (subject to possible extensions not to exceed 15 months if specified regulatory clearances remain outstanding) for outstanding regulatory matters, for an uncured material breach, or if a law, order or other regulatory impediment prohibits consummation of the Transactions. The Share Purchase Agreement is also terminable by Purchaser in the event of the failure to satisfy certain regulatory-related conditions or the occurrence of certain adverse developments in regard to the regulation of the Target Company. The Share Purchase Agreement does not provide for any termination fee payable by the Sellers or Purchaser upon termination. Following termination, the Share Purchase Agreement becomes void and generally imposes no further liability, except for willful and material breaches or fraud and provisions that expressly survive termination, including confidentiality. Resale Registration In connection with the Closing, Circle will be required to file a prospectus supplement to the Shelf Registration Statement filed on Form S-3 on August 5, 2026, which will provide for the resale of all shares of Circle Common Stock issued to the Sellers and Equity Award Holders as Aggregate Consideration on the Closing Date. Circle will use its commercially reasonable efforts to keep the registration statement effective until the shares issued in the Transaction have been sold or no longer require registration. Circle may suspend use of such prospectus supplement under specified circumstances for periods not to exceed 60 consecutive days at one time or 120 days in the aggregate in any 12-month period. Remedies; Specific Performance Each party is entitled to specific performance or injunctive relief to prevent or remedy a breach of the Share Purchase Agreement, without the need to post any bond or to prove that monetary damages would be inadequate, in addition to any other remedy at law or in equity.
