Beginning the fourth quarter of 2025, Nubank introduced its Managerial P&L, representing an evolution in our disclosure framework to better explain value creation across an increasingly multi-product, multi-segment, and multi-country platform. The Managerial P&L is a structural, complementary reorganization of IFRS line items designed to enhance comparability as the business scales, grounded in economic and operational substance. This framework preserves net income, cash flow, and capital, is fully reconciled to IFRS, and is designed for external assurance. All financial metrics presented reflect this framework. A full reconciliation of non-IFRS measures to the most directly comparable IFRS measures is available in our Managerial P&L Reconciliation Report and in the appendix of the earnings presentation.

A non-IFRS financial measure is generally defined as a numerical measure of historical or future financial performance or financial position that purports to measure financial performance but excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. These non-IFRS financial measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with IFRS. Adjusted Net Income is defined as profit (loss) attributable to shareholders of the parent company for the period, adjusted for the expenses and allocated tax effects on share-based compensation. Adjusted Net Income is presented because management believes that this non-IFRS financial measure can provide useful information to investors, securities analysts and the public in their review of the operating and financial performance of the Company, although it is not calculated in accordance with IFRS or any other generally accepted accounting principles and should not be considered as a measure of performance in isolation. Nu also uses Adjusted Net Income as a key profitability measure to assess the performance of the business. Nu believes Adjusted Net Income is useful to evaluate operating and financial performance for the following reasons: Adjusted Net Income is widely used by investors and securities analysts to measure a company’s operating performance without regard to items that can vary substantially from company to company and from period to period, depending on their accounting and tax methods, the book value and the market value of their assets and liabilities, and the method by which their assets were acquired; and Non-IFRS Financial Measures and Reconciliations Non-cash equity grants made to executives, employees or consultants at a certain price and point in time, and their hedge accounting effects for the corporate tax and social wages and their income tax effects, do not necessarily reflect how the business is performing at any particular time and the related expenses (and their subject impacts in the market value of assets and liabilities) are not key measures of core operating performance. Adjusted Net Income is not a substitute for Net Income, which is the IFRS measure of earnings. Additionally, the calculation of Adjusted Net Income (Loss) may be different from the calculation used by other companies, including competitors in the technology and financial services industries, because other companies may not calculate these measures in the same manner as we do, and therefore, measure may not be comparable to those of other companies. Q4’25 Results 26 Non-IFRS Financial Measures and Reconciliations The new managerial P&L reporting framework is intended to facilitate understanding of the underlying operational and economic drivers of the Company’s results and how value is generated across products, segments, and geographies. The managerial P&L line items are derived exclusively from the Company’s IFRS financial statements and are constructed through a defined set of operational reclassifications and tax-equivalency adjustments. Such reclassifications and adjustments are managerial and 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 between 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 view are applied consistently across periods. This marks the formal introduction of the framework. Any future enhancements to the framework or its presentation will be disclosed transparently and supported by appropriate reconciliation to IFRS results. IFRS consolidated financial statements remain the sole basis for statutory reporting and constitute the source of truth for all accounting purposes. Source: Nu.

FX Neutral measures are presented because management believes that these non-IFRS financial measures can provide useful information to investors, securities analysts and the public in their review of operating and financial performance, although they are not calculated in accordance with IFRS or any other generally accepted accounting principles and should not be considered as a measure of performance in isolation. The FX Neutral measures were calculated to present what such measures in preceding periods would have been had exchange rates remained stable from these preceding periods until the date of the Company's most recent financial information. The FX Neutral measures for the three months ended December 31, 2024 were calculated by multiplying the as reported amounts of Adjusted Net Income and the key business metrics for such period by the average Brazilian reais / U.S. dollars exchange rate for the three months ended December 31, 2024 (R$5.8402 to US$1.00) and using such results to re-translate the corresponding amounts back to U.S. dollars by dividing them by average based on the USD/BRL spot last price rate for all business days within the reporting in the three months ended December 31, 2024 (R$5,3988 to US$1.00), so as to present what certain of statement of profit and loss amounts and key business metrics would have been had exchange rates remained stable from this past period until the three months ended December 31, 2025. Non-IFRS Financial Measures and Reconciliations The average Brazilian reais/U.S. dollars exchange rates were calculated as the average based on the USD/BRL spot last price rate for all business days within the reporting in the three months ended December 31, 2025 and 2024 as reported by Bloomberg. FX Neutral measures for deposits and interest-earning portfolio were calculated by multiplying the as reported amounts as of each date, by the spot Brazilian reais/U.S. dollars exchange rates as of each date and using such results to re-translate the corresponding amounts back to U.S. dollars by dividing them by using the spot last price rate as December 31, 2025 (R$5.4956 to US$1.00) so as to present what these amounts would have been had exchange rates been the same on December 31, 2024. The Brazilian reais/U.S. dollars exchange rates were calculated using rates as of such dates as reported by Bloomberg.
