Synovus Reports Earnings for Fourth Quarter of 2013

Total Loans Grow $346 Million or 7.0% Annualized

Columbus, Ga., January 21, 2014 – Synovus Financial Corp. (NYSE: SNV) today reported financial results for the quarter ended December 31, 2013.

Fourth Quarter Results

“We were pleased to report 7% annualized sequential quarter loan growth, driven primarily by C&I and retail lending,” said Kessel D. Stelling, Chairman and CEO of Synovus. “Partnerships between our local bank divisions and large corporate banking teams across our five-state footprint produced meaningful results, and we saw growth in key markets such as Atlanta, Tampa, Charleston, Nashville, Savannah, and Columbus. HELOC and private client mortgages drove the growth in retail loans during the quarter. Credit quality continued to improve, and our net interest margin remained stable. Additionally, our focus on cost savings continued as we completed implementation of initiatives necessary to achieve the $30 million in expense reductions announced at the beginning of the year.”

Core Performance

Pre-tax, pre-credit costs income was $96.3 million for the fourth quarter of 2013, an increase of $868 thousand from $95.4 million for the third quarter of 2013.

Balance Sheet Fundamentals

Credit Quality

  Broad based improvement in credit quality continued.

Capital Ratios

Stelling concluded, “Our team’s 125^th anniversary celebration during the fourth quarter was an appropriate way to close out a successful year defined by several important achievements, including upgrades from three rating agencies, two successful capital raises, and the redemption of our TARP obligation. Entering 2014, our capital position is strong, our customers remain our central focus, and our lending engine is gaining good traction. While expense management continues to be a major focus for our company, with additional reductions of approximately $30 million planned for 2014, we are also making strategic investments in talent, technology, and marketing that will improve our customers’ experience and support future growth.”

Forward-Looking Statements

This press release 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,” “should,” “predicts,” “could,” “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 commercial banking industry and economy in general. 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, strategic investments, expense initiatives, and future profitability; 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 report. 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, 2012 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.

Use of Non-GAAP Financial Measures

The measures entitled core deposits, core deposits excluding time deposits, tangible common equity to tangible assets ratio, Tier 1 common equity ratio, net income available to common shareholders excluding litigation loss contingency expense and restructuring charges, pre-tax, pre-credit costs 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 deposits, total shareholders’ equity to total assets ratio, Tier 1 capital to risk-weighted assets ratio, net income available to common shareholders, income (loss) 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 deposits, total shareholders’ equity to total assets ratio, Tier 1 capital to risk-weighted assets ratio, net income available to common shareholders, income (loss) before income taxes, or 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 core deposits, core deposits excluding time deposits, tangible common equity to tangible assets ratio, Tier 1 common equity ratio, net income available to common shareholders excluding litigation loss contingency expense and restructuring charges, pre-tax, pre-credit costs income, and adjusted non-interest expense, and the reconciliation of these measures to total deposits, total shareholders’ equity to total assets ratio, Tier 1 capital to risk-weighted assets ratio, income (loss) before income taxes, and total non-interest expense are set forth in the tables below.
