You should not rely on any forward-looking statements as predictions of future events. You should not expect us to update any forward-looking statements, except as required by law. All written or oral forward-looking statements attributable to us are expressly qualified in their entirety by this cautionary notice, together with those risks and uncertainties described in "Risk factors" in our annual report on Form 10-K for the fiscal year ended December 31, 2024 filed on March 5, 2025, and in our other filings with the U.S. Securities and Exchange Commission (the "SEC"), which are available at the SEC's website https://www.sec.gov .

Non-GAAP Financial Measures The Company supplements its financial results that are determined in accordance with accounting principles generally accepted in the United States of America ("GAAP") with non-GAAP financial measures, such as "preprovision net revenue (PPNR)", "core pre-provision net revenue (Core PPNR)", "core noninterest income", "core noninterest expense", "core net income", "core earnings per share (basic and diluted)", "core return on assets (Core ROA)", "core return on equity (Core ROE)", "core efficiency ratio", and "tangible stockholders' equity (book value) per common share" . This supplemental information is not required by, or is not presented in accordance with GAAP. The Company refers to these financial measures and ratios as "non-GAAP financial measures". We use certain non-GAAP financial measures, including those mentioned above, both to explain our results to shareholders and the investment community and in the internal evaluation and management of our business. Management believes that these supplementary non-GAAP financial measures and the information they provide are useful to investors since these measures permit investors to view our performance using the same tools that our management uses to evaluate our past performance and prospects for future performance. While we believe that these non-GAAP financial measures are useful in evaluating our performance, this information should be considered as supplemental and not as a substitute for or superior to the related financial information prepared in accordance with GAAP. Additionally, these non-GAAP financial measures may differ from similar measures presented by other companies. Appendix 1 reconciles these non-GAAP financial measures to reported results.
