NU HOLDINGS LTD. Floor 4, Willow House, Cricket Square Grand Cayman, KY1-9010, Cayman Islands PROXY STATEMENT General The Board of Directors of Nu Holdings Ltd. (the “Company” or “we”) is soliciting proxies for the annual general meeting of shareholders (the “AGM”) of the Company to be held on August 6, 2026 at 8:00 a.m., Brasilia time (UTC-3). The AGM will be held at the offices of the Company, located at Rua Capote Valente, 39, Pinheiros, São Paulo-SP, 05409-000, Brazil. The AGM will be held in accordance with Cayman Islands law and the amended and restated memorandum and articles of association of the Company and shareholders can attend in person or electronically. You will be able to attend the AGM online by visiting meetnow.global/M5FDQAW. You will also be able to vote your shares online by attending the AGM via this webcast. To participate in the AGM, you will need to review the information included on the proxy card or in the instructions that accompanied your proxy materials. On July 6, 2026, we published a notice of the AGM and our proxy materials on the Investor Relations section of the Company’s website at https://www.investidores.nu/ and on the SEC’s website at https://www.sec.gov and 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. Record Date, Share Ownership and Quorum Only the holders of record of Class A ordinary shares (the “Class A Ordinary Shares”) and Class B ordinary shares (the “Class B Ordinary Shares” and together with the Class A Ordinary Shares, the “Ordinary Shares”) of the Company as at the close of business on June 26, 2026, Brasilia time (UTC-3) (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 for the AGM. As of the close of business on the Record Date, 4,830,484,570 Ordinary Shares were issued and outstanding, including 3,807,883,872 Class A Ordinary Shares and 1,022,600,698 — Class B Ordinary Shares. One or more shareholders holding not less than a majority in aggregate 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 Ordinary 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 Ordinary Share issued and outstanding as of the close of business on the Record Date is entitled to twenty 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). Internet Availability of Proxy Materials We are furnishing proxy materials to our shareholders primarily via the Internet, instead of mailing printed copies of those materials to each shareholder. On or about July 6, 2026, we first mailed to our shareholders a Notice of Internet Availability containing instructions on how to access our proxy materials. The Notice of Internet Availability of Proxy Materials directs shareholders to a website where they can access our proxy materials, including our proxy statement and our annual report, and view instructions on how to vote via the Internet, mobile device or by proxy card. This process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the AGM, and help conserve natural resources. If you received a Notice of Internet Availability of Proxy Materials and would prefer to receive a paper copy of our proxy materials, please follow the instructions included in the Notice of Internet Availability of Proxy Materials. Voting by Holders of Ordinary Shares Ordinary 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, the proxy holder will vote in favour of the item(s) set forth in the proxy card. 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 Ordinary Shares affirmatively abstains from voting on any particular resolution, the votes attaching to such Ordinary Shares will not be included or counted in the determination of the number of Ordinary 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 August 4, 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 Computershare Inc. (“Computershare”) (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 Computershare. You may provide voting instructions by returning a proxy card. You also may attend the AGM and vote in person. If you own Ordinary 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 Ordinary 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 [email protected], or a duly executed proxy bearing a later date (which must be received by us no later than the date set forth below) or by attending the AGM and voting in person. A beneficial owner owning Ordinary 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 August 4, 2026.
