All statements other than statements of historical fact are forward-looking statements.

These forward-looking statements include, among others, our expectations on credit trends and key credit metrics; expectations regarding deposits, loan growth and the net interest margin; expectations on our growth strategy, expense initiatives, and future profitability; expectations regarding our capital management, including our announced share repurchase program, and the assumptions underlying our 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 press release.

Use of Non-GAAP Financial Measures

The measures entitled average core deposits; average core deposits excluding average state, county, and municipal deposits; Tier 1 common equity ratio; tangible common equity to tangible assets ratio; adjusted net income per common share, diluted; adjusted pre-tax, pre-credit cost income; and adjusted non-interest expense are not measures recognized under U.S. generally accepted accounting principles (GAAP) and therefore are considered non-GAAP financial measures. The most comparable GAAP measures are total average deposits; Tier 1 capital to risk-weighted assets ratio; total shareholders’ equity to total assets ratio; net income per common share, diluted; income before income taxes; and total non-interest expense, respectively.

Synovus believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist management and investors in evaluating Synovus’ capital strength and the performance of its core business. These non-GAAP financial measures should not be considered as substitutes for total average deposits; Tier 1 capital to risk-weighted assets ratio; total shareholders’ equity to total assets ratio; net income per common share, diluted; income before income taxes; and total non-interest expense determined in accordance with GAAP and may not be comparable to other similarly titled measures at other companies.

The computations of average core deposits; average core deposits excluding average state, county, and municipal deposits; Tier 1 common equity ratio; tangible common equity to tangible assets ratio; adjusted net income per common share, diluted; adjusted pre-tax, pre-credit cost income; and adjusted non-interest expense; and the reconciliation of these measures to total average deposits; Tier 1 capital to risk-weighted assets ratio; total shareholders’ equity to total assets ratio; net income per common share, diluted; income before income taxes; and total non-interest expense are set forth in the tables below.
