(the “Company” or “we”) is soliciting proxies for the annual general meeting of shareholders (the “AGM”) of the Company to be held on April 23, 2026 at 9:00 a.m., Cayman Islands time (GMT-5). The AGM will be held at the offices of the Company at Block 12D Parcel 33 and 95, 18 Forum Lane, Camana Bay, P.O. Box 10240, Grand Cayman KY1-1002, Cayman Islands.

On or before March 19, 2026, we mailed to our shareholders our proxy materials, including our proxy statement, the notice to shareholders of our AGM and the proxy card, along with instructions on how to vote using the proxy card provided therewith. This proxy statement can also be accessed, free of charge, on the Investor Relations section of the Company’s website at https://investors.stone.co/ and on the SEC’s website at www.sec.gov.

Record Date, Share Ownership and Quorum

Only the holders of record of Class A common shares (the “Class A Common Shares”) and Class B common shares (the “Class B Common Shares” and together with the Class A Common Shares, the “Common Shares”) of the Company as at the close of business on March 13, 2026, EST (the “Record Date”) are entitled to receive notice of and attend the AGM and any adjournment thereof. No person shall be entitled to vote at the AGM unless it is registered as a shareholder of the Company on the Record Date.

As of the close of business on the Record Date, 245,197,993 Common Shares were issued and outstanding, including 231,146,829 Class A Common Shares and 14,051,164 Class B Common Shares. One or more shareholders holding not less than one-third in aggregate of the voting power of all shares in issue and entitled to vote, present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative, constitutes a quorum of the shareholders.

Voting and Solicitation

Each Class A Common Share issued and outstanding as of the close of business on the Record Date is entitled to one vote at the AGM. Each Class B Common Share issued and outstanding as of the close of business on the Record Date is entitled to ten votes at the AGM. The resolutions to be put to the vote at the AGM will be approved by an ordinary resolution (i.e. a simple majority of the votes cast, by or on behalf of, the shareholders attending and voting at the AGM).

Voting by Holders of Common Shares

Common Shares that are properly voted, for which proxy cards are properly executed and returned within the deadline set forth below, will be voted at the AGM in accordance with the directions given. If no specific instructions are given in such proxy cards, Common Shares represented by the proxy card will be voted in favor of the resolution in question. The proxy holder will also vote in the discretion of such proxy holder on any other matters that may properly come before the AGM, or at any adjournment thereof. Where any holder of Common Shares affirmatively abstains from voting on any particular resolution, the votes attaching to such Common Shares will not be included or counted in the determination of the number of Common Shares present and voting for the purposes of determining whether such resolution has been passed (but they will be counted for the purposes of determining the quorum, as described above).

Proxies submitted by registered shareholders and street shareholders (by returning the proxy card) must be received by us no later than 11:59 p.m., Eastern time, on April 22, 2026 to ensure your representation at our AGM.

The manner in which your shares may be voted depends on how your shares are held. If you own shares of record, meaning that your shares are represented by book entries in your name so that you appear as a shareholder on the records of Equiniti Trust Company, LLC (“EQ”) (i.e., you are a registered shareholder), our stock transfer agent, this proxy statement, the notice of AGM and the proxy card will be mailed to you by EQ. You may provide voting instructions by returning a proxy card. You also may attend the AGM and vote in person. If you own Common Shares of record and you do not vote by proxy or in person at the Annual Meeting, your shares will not be voted.

If you own shares in street name (i.e., you are a street shareholder), meaning that your shares are held by a bank, brokerage firm, or other nominee, you are then considered the “beneficial owner” of shares held in “street name” and, as a result, this proxy statement, the notice of AGM and the proxy card will be provided to you by your bank, brokerage firm, or other nominee holding the shares. You may provide voting instructions to them directly by returning a voting instruction form received from that institution. If you own Common Shares in street name and attend the AGM, you must obtain a “legal proxy” from the bank, brokerage firm, or other nominee that holds your shares in order to vote your shares at the meeting and present your voting information card.

Revocability of Proxies

Registered shareholders may revoke their proxy or change voting instructions before shares are voted at the AGM by submitting a written notice of revocation to our Investor Relations Department at investors@stone.co, or a duly executed proxy bearing a later date (which must be received by us no later than April 22, 2026) or by attending the AGM and voting in person. A beneficial owner owning Common Shares in street name may revoke or change voting instructions by contacting the bank, brokerage firm, or other nominee holding the shares or by obtaining a legal proxy from such institution and voting in person at the AGM. If you are not planning to attend in person our AGM, to ensure your representation at our AGM, revocation of proxies submitted by registered shareholders and street shareholders (by returning a proxy card) must be received by us no later than 11:59 p.m., Eastern time, on April 22, 2026.
