1 Earnings Results Fourth Quarter 2024 Exhibit 99.3

2 This slide presentation and certain of our other filings with the Securities and Exchange Commission contain statements that constitute "forward-looking statements" within the meaning of, and subject to the protections of, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are forward-looking statements. You can identify these forward-looking statements through Synovus' use of words such as "believes," "anticipates," "expects," "may," "will," "assumes," "predicts," "could," "should," "would," "intends," "targets," "estimates," "projects," "plans," "potential" and other similar words and expressions of the future or otherwise regarding the outlook for Synovus' future business and financial performance and/or the performance of the banking industry and economy in general. These forward-looking statements include, among others, statements on our expectations related to (1) loan growth and loan mix; (2) deposit growth, mix, pricing, and costs; (3) net interest income and net interest margin; (4) revenue growth; (5) non-interest expense; (6) credit trends and key credit performance metrics; (7) our future operating and financial performance; (8) our strategy and initiatives for future revenue growth, balance sheet optimization, capital management, and expense management; (9) our effective tax rate; and (10) our assumptions underlying these expectations. Prospective investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve known and unknown risks and uncertainties which may cause the actual results, performance or achievements of Synovus to be materially different from the future results, performance or achievements expressed or implied by such forward-looking statements. Forward-looking statements are based on the information known to, and current beliefs and expectations of, Synovus' management and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this presentation. Many of these factors are beyond Synovus' ability to control or predict. These forward-looking statements are based upon information presently known to Synovus' management and are inherently subjective, uncertain and subject to change due to any number of risks and uncertainties, including, without limitation, the risks and other factors set forth in Synovus' filings with the Securities and Exchange Commission, including its Annual Report on Form 10-K for the year ended December 31, 2023 under the captions "Cautionary Notice Regarding Forward-Looking Statements" and "Risk Factors" and in Synovus' quarterly reports on Form 10-Q and current reports on Form 8-K. We believe these forward- looking statements are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations and speak only as of the date that they are made. We do not assume any obligation to update any forward-looking statements as a result of new information, future developments or otherwise, except as otherwise may be required by law. This slide presentation contains certain non-GAAP financial measures determined by methods other than in accordance with generally accepted accounting principles. Such non-GAAP financial measures include the following: adjusted net income available to common shareholders; adjusted diluted earnings per share; adjusted return on average assets; return on average tangible common equity; adjusted return on average tangible common equity; adjusted non-interest revenue; adjusted total revenue taxable equivalent (TE); adjusted non-interest expense; adjusted tangible efficiency ratio; tangible common equity ratio; and adjusted pre-provision net revenue (PPNR). The most comparable GAAP measures to these measures are net income available to common shareholders; diluted earnings (loss) per share; return on average assets; return on average common equity; total non-interest revenue; total revenue; total non-interest expense; efficiency ratio-TE; total Synovus Financial Corp. shareholders' equity to total assets ratio; and PPNR, respectively. Management believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist management and investors in evaluating Synovus' operating results, financial strength, the performance of its business and the strength of its capital position. However, these non-GAAP financial measures have inherent limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of operating results or capital position as reported under GAAP. The non-GAAP financial measures should be considered as additional views of the way our financial measures are affected by significant items and other factors, and since they are not required to be uniformly applied, they may not be comparable to other similarly titled measures at other companies. Adjusted net income available to common shareholders, adjusted diluted earnings per share and adjusted return on average assets are measures used by management to evaluate operating results exclusive of items that are not indicative of ongoing operations and impact period-to-period comparisons. Return on average tangible common equity and adjusted return on average tangible common equity are measures used by management to compare Synovus' performance with other financial institutions because it calculates the return available to common shareholders without the impact of intangible assets and their related amortization, thereby allowing management to evaluate the performance of the business consistently. Adjusted non-interest revenue and adjusted total revenue TE are measures used by management to evaluate non-interest revenue and total revenue exclusive of net investment securities gains (losses), fair value adjustments on non-qualified deferred compensation, and other items not indicative of ongoing operations that could impact period-to-period comparisons. Adjusted non-interest expense and the adjusted tangible efficiency ratio are measures utilized by management to measure the success of expense management initiatives focused on reducing recurring controllable operating costs. The tangible common equity ratio is used by stakeholders to assess our capital position. Adjusted PPNR is used by management to evaluate PPNR exclusive of items that management believes are not indicative of ongoing operations and impact period-to-period comparisons. The computations of the non-GAAP financial measures used in this slide presentation are set forth in the appendix to this slide presentation. Management does not provide a reconciliation for forward-looking non-GAAP financial measures where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the occurrence and the financial impact of various items that have not yet occurred, are out of Synovus’ control, or cannot be reasonably predicted. For the same reasons, Synovus’ management is unable to address the probable significance of the unavailable information. Forward-looking non-GAAP financial measures provided without the most directly comparable GAAP financial measures may vary materially from the corresponding GAAP financial measures.
