Non-GAAP Measures

This press release contains information prepared in conformity with GAAP as well as non-GAAP information. It is management’s intent to provide non-GAAP financial information to enhance understanding of its consolidated financial information as prepared in accordance with GAAP. This non-GAAP information should be considered by the reader in addition to, but not instead of, the financial statements prepared in accordance with GAAP. Each non-GAAP financial measure and the most directly comparable GAAP financial measure are presented so as not to imply that more emphasis should be placed on the non-GAAP measure. The non-GAAP financial information presented may be determined or calculated differently by other companies.

Additional information about non-GAAP financial measures, including, but not limited to, net revenue, adjusted earnings, adjusted EBITDA and adjusted EPS, and a reconciliation of those measures to the most directly comparable GAAP measures is included on pages 11 to 15 in the financial schedules of this release.

Forward-Looking Statements

This press release contains “forward-looking statements” – that is, statements related to future, not past, events. Forward-looking statements often address our expected future business and financial performance and often contain words such as “expect,” “anticipate,” “intend,” “believe,” “should,” “plan,” “potential,” “will,” “could,” and similar expressions. These forward-looking statements include, among others, statements regarding TSYS’ earnings guidance for 2017 total revenues, net revenue, diluted EPS and adjusted diluted EPS, and the

assumptions underlying such statements. These statements are based on the current beliefs and expectations of TSYS’ management, are based on management’s assumptions and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by the forward-looking statements. A number of important factors could cause actual results or events to differ materially from those contemplated by our forward-looking statements in this press release. Many of these factors are beyond TSYS’ ability to control or predict. These factors include, but are not limited to, the material breach of security of any of TSYS’ systems; TSYS’ ability to integrate acquisitions and achieve the anticipated growth opportunities and other benefits of the acquisitions, particularly the TransFirst acquisition; the effect of current domestic and worldwide economic conditions; risks associated with foreign operations, including adverse developments with respect to foreign currency exchange rates, and in particular with respect to the current environment, adverse developments with respect to foreign currency exchange rates as a result of the United Kingdom’s decision to leave the European Union (Brexit); expenses incurred associated with the signing of a significant client; TSYS does not convert clients’ portfolios as scheduled; the deconversion of a significant client; changes occur in laws, rules, regulations, credit card association rules, prepaid industry rules or other industry standards affecting TSYS and our clients that may result in costly new compliance burdens on TSYS and our clients and lead to a decrease in the volume and/or number of transactions processed or limit the types and amounts of fees that can be charged to customers, and in particular the CFPB’s new rule regarding prepaid financial products; the costs and effects of litigation, investigations or similar matters or adverse facts and developments relating thereto; adverse developments with respect to the payment card industry in general, including a decline in the use of cards as a payment mechanism; and growth rates of TSYS’ existing clients are lower than anticipated or attrition rates of existing clients are higher than anticipated. Additional risks and other factors that could cause actual results or events to differ materially from those contemplated in this release can be found in TSYS’ filings with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-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. TSYS disclaims any obligation to update any forward-looking statements as a result of new information, future developments or otherwise except as required by law.
