Slide 2 — Notes to users

Notes to users 1) This supplementary financial information (SFI) is unaudited and should be read in conjunction with the Report to Shareholders for all quarters of 2026 and with the 2025 Annual Report (including audited consolidated financial statements and accompanying management’s discussion and analysis) prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), unless otherwise indicated. IFRS represent Canadian generally accepted accounting principles (GAAP). Additional financial information is also available through our quarterly investor presentations as well as the quarterly conference call webcast. All amounts are in millions of Canadian dollars, unless otherwise indicated. 2) Information related to regulatory capital as well as Pillar 3 and risk disclosures required by the Enhanced Disclosure Task Force (EDTF) is provided in the document entitled Supplementary Regulatory Capital and Pillar 3 Disclosure, which is available on the Bank’s website at nbc.ca. 3) Non-GAAP Financial Measures and Other Financial Measures The Bank uses non-GAAP financial measures that do not have standardized meanings under GAAP and that therefore may not be comparable to similar measures used by other companies. Presenting non-GAAP financial measures helps readers to better understand how management analyzes results, shows the impacts of specified items on the results of the reported periods, and allows readers to better assess results without the specified items if they consider such items not to be reflective of the underlying performance of the Bank’s operations. For additional information on non-GAAP financial measures, see pages 15 and 16 in this document and the Financial Reporting Method section on pages 5 to 12 in the Report to Shareholders for the Third Quarter of 2026, which is available on the Bank's website at nbc.ca or the SEDAR+ website at sedarplus.ca. Other Financial Measures For additional information on the composition of non-GAAP ratios and supplementary financial measures, as well as on capital management measures, see the Financial Reporting Method and Glossary sections on pages 5 to 12 and 45 to 48, respectively, in the Report to Shareholders for the Third Quarter of 2026, which is available on the Bank's website at nbc.ca or the SEDAR+ website at sedarplus.ca.

(3) In Q2 2026, changes were made to the presentation of the number of employees (full-time equivalent) to better align with the management structure, notably the transfer to the business segment of the technology and operations services employees, who were previously presented under the Other heading of the segment results. This change has no impact on the segment’s financial results as the related expenses were already reflected in the business segment through the cost allocation process. Comparative figures have not been restated.
