Nu Holdings’ Responsibilities The management of Nu Holdings is responsible for preparing the Managerial P&L Reconciliation Report in accordance with the managerial criteria described in the Company’s specific internal policy, and for the information contained therein. The management of Nu Holdings is also responsible for preparing the accompanying statement at page 04. This responsibility includes designing, implementing and maintaining internal controls relevant to the preparation and presentation of the supplementary consolidated financial information included in the Managerial P&L Reconciliation Report to ensure that such information is free from material misstatement, whether due to fraud or error. Our Responsibilities Our responsibility is to examine Company’s process for compiling and presenting the supplementary consolidated financial information included in the Managerial P&L Reconciliation Report and to report thereon in the form of an independent limited assurance conclusion based on the evidence obtained. We conducted our engagement in accordance with the International Standard on Assurance Engagements (ISAE) 3000 (Revised), Assurance Engagements Other Than Audits or Reviews of Historical Financial Information issued by the International Auditing and Assurance Standards Board. That standard requires that we plan and perform our procedures to obtain a meaningful level of assurance about whether the process for compiling and presenting the supplementary consolidated financial information included in the Managerial P&L Reconciliation Report are in accordance with the managerial 3 ABCD criteria described in the Company’s specific internal policy, and summarized in the sections “Definition of Managerial P&L Lines”, “Reconciliation Bridge” and “Methodology and Presentation Note” of the Managerial P&L Reconciliation Report, in all material respects, as the basis for our limited assurance conclusion. The firm applies International Standard on Quality Management 1, which requires the firm to design, implement and operate a system of quality management including policies or procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements. We have complied with the independence and other ethical requirements of the International Ethics Standards Board for Accountants’ International Code of Ethics for Professional Accountants (including International Independence Standards) (IESBA Code), which is founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behavior. The procedures selected depend on our understanding of the process for compiling and presenting the supplementary consolidated financial information included in the Managerial P&L Reconciliation Report and other engagement circumstances, and our consideration of areas where material misstatements are likely to arise. The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for, a reasonable assurance engagement. Consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance engagement been performed. Conclusion Our conclusion has been formed on the basis of, and is subject to, the matters outlined in this report. We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our conclusion. Based on the procedures performed and evidence obtained over the Company’s process for compiling and presenting the supplementary consolidated financial information included in the Managerial P&L Reconciliation Report, nothing has come to our attention that causes us to believe that Nu Holdings’s management statement that the supplementary consolidated financial information included in the Managerial P&L Reconciliation Report for the three‑month period ended 31 March 2026 and 31 March 2025 is properly prepared, in all material respects, based on the criteria described in the Company’s specific internal policy and summarized in the sections “Definition of Managerial P&L Lines”, “Reconciliation Bridge” and “Methodology and Presentation Note” of the Managerial P&L Reconciliation Report, is not fairly stated.

IFRS consolidated financial statements remain the sole basis for statutory reporting and constitute the source of truth for all accounting purposes, the managerial P&L line items, which do not represent a full set of financial statements prepared in accordance with IFRS or any other GAAP ("Generally Accepted Accounting Principles”), are derived exclusively from the Company's IFRS unaudited interim condensed consolidated financial statements and are constructed through a defined set of operational reclassifications and tax-equivalency adjustments. These adjustments do not affect the Company's reported net income, cash flows, equity, or regulatory capital metrics prepared in accordance with IFRS Operational reclassifications are applied to align income, costs, and expenses with the economic activities to which they relate, with the objective of improving comparability, analytical consistency, and transparency of operating performance. These reclassifications represent presentation-only changes within income statement line items. As part of the managerial P&L view, the Company applies a defined set of tax-equivalency adjustments designed to improve comparability of pre-tax performance metrics for managerial analysis across components subject to specific statutory tax treatments. Conceptually, tax-equivalency adjustments normalize statutory tax effects so that the underlying economic contribution of certain products, services, and activities can be compared on a consistent pre-tax basis. These adjustments are net-income neutral and do not alter reported income tax expenses under IFRS or cash taxes paid. The methodologies, definitions, and classification principles underlying the Managerial P&L are applied consistently across periods. Any future enhancements to the framework or its presentation will be disclosed transparently and supported by appropriate reconciliation to IFRS results. 7
