On May 28, 2019, M. Troy Woods, Chairman and CEO of Total System Services, Inc., circulated the following letter via email to all team members of Total System Services, Inc.

Dear Team Members,

Today marks a major milestone for TSYS as we announce that our board of directors has approved an agreement for a merger of equals with Global Payments, one of the world’s leading providers of payment technology and software solutions for businesses and merchants, in an all-stock transaction. This combination will create a premier global payments technology company at scale in the largest and most attractive markets worldwide. The combination of TSYS and Global Payments represents a strategic opportunity to unite two leaders in the payments industry with a shared vision and passion for providing innovative products and unsurpassed service.

Global Payments and its 11,000 employees currently serve more than 2.5 million customer locations and process in excess of 17 billion transactions with $700 billion in volume settled. Together, the combined company generated approximately $8.6 billion in adjusted net revenues and network fees on a pro forma basis for the 12 months ended March 31, 2019. TSYS and Global Payments will be a payments powerhouse, with the combined company listed among the Fortune 500 and expected to rank as a Top 2 global acquirer, the #1 Issuer Solutions provider in the U.S., Canada, UK and Ireland, and a Top 2 U.S. prepaid consumer solutions provider.

Our merger of equals with Global Payments will unite two great companies, both rich in heritage. We share common values and a culture of putting people first as evidenced by Global Payments’ stated value of “Our people come first.” Global Payments is widely viewed as one of the most transparent, fair and honest players in the payments industry, making them a perfect fit with our People-Centered Payments brand.

This is truly a merger of equals. Global Payments shareholders will own approximately 52 percent and TSYS shareholders will own approximately 48 percent of the combined company. Half of the executive team will be from TSYS, and half of the board will consist of directors from TSYS. The combined company will be dually headquartered in Atlanta and Columbus, Ga., and will operate under the Global Payments name. In addition, the combined company will conduct its Issuer Solutions business under the name TSYS and the Consumer Solutions business will continue to go to market under the Netspend name.

From a leadership perspective, I will serve as Chairman of the Board of the combined company, and Jeff Sloan, currently CEO of Global Payments, will serve as CEO of the combined company. Cameron Bready, Global Payments’ CFO, will serve as President and COO, while Paul Todd will continue in his role as CFO for the combined company. Kriss Cloninger, currently our lead director, will become the lead director of the combined board of directors.

You may be wondering why TSYS is pursuing this merger of equals given our success and position of strength. In the payments industry, in which our larger peers are actively consolidating to gain scale, TSYS has approached this opportunity to embrace disruption and strategically position the company to be a winner over the long-term. In addition to creating a stronger, high growth player in the payments space, the combined company is expected to offer customers more compelling end-to-end solutions that span issuer, consumer and merchant services, unmatched global reach and increased cross-selling opportunities. And, although Global Payments’ business has primarily centered on technology and software for merchants, let me reaffirm our total commitment to our issuer and consumer lines of business. They will continue to be major components of the payment solutions offered by the new combined company.

While I know you have a lot of questions about the future, I encourage you to embrace this change as a very positive move for our company. The transaction, which is subject to regulatory and shareholder approvals and contractual closing conditions, is expected to close in the fourth quarter of 2019. Until then, it will be business as usual for both TSYS and Global Payments, so please keep serving our customers with your typical passion and excellence. I hope all of you feel the tremendous momentum and excitement about the world of opportunity we have before us. The TSYS and Global Payments brands and cultures are a perfect fit, and I could not be prouder to link arms as a combined team.

I also want to thank each one of you who have worked so tirelessly to make TSYS the strong and well-respected company it is today. We have a more than 35 year legacy of doing the right thing, caring for one another, our customers and communities – and I have no intention of letting that heritage disappear. We are people-centered and performance-driven today, and we will be the same tomorrow. This merger positions us to continue this noble and worthwhile work for many years to come. This is how we TSYS!

To gain further insight into this merger, I encourage you to review the press release available on teamWORKS or tsys.com. Thanks to all for your hard work, your dedication and your excitement as we embark on writing the next chapter in the history of TSYS.

M. Troy Woods | Chairman, President and CEO | TSYS

Words such as “believes,” “anticipates,” “expects,” “intends,” “targeted,” “estimates,” “forecasts,” “projects,” “plans,” “may,” “could,” “should,” “would,” and similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying these statements. Such forward-looking statements include, but are not limited to, statements about the strategic rationale and financial benefits of the transaction, including expected future financial and operating results and the combined company’s plans, objectives, expectations and intentions. All statements that address operating performance, events or developments that we expect or anticipate will occur in the future — including statements relating to projections of revenue, income or loss, earnings or loss per share, the payment or nonpayment of dividends, capital structure and other financial items; statements of plans and objectives of TSYS or Global Payments or their management or Board of Directors, including those relating to products or services; and statements of future economic performance — are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained, and therefore actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. In addition to factors previously disclosed in TSYS’ and Global Payments’ reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of TSYS and Global Payments to terminate the merger agreement; the outcome of any legal proceedings that may be instituted against TSYS, Global Payments or their respective directors; the ability to obtain regulatory approvals and meet other closing conditions to the merger on a timely basis or at all, including the risk that regulatory approvals required for the merger are not obtained on a timely basis or at all, or are obtained subject to conditions that are not anticipated or that could adversely affect the combined company or the expected benefits of the transaction; the ability to obtain approval by TSYS shareholders and Global Payments shareholders on the expected terms and schedule; difficulties and delays in integrating the TSYS and Global Payments businesses, including with respect to implementing systems to prevent a material security breach of any internal systems or to successfully manage credit and fraud risks in business units; failing to fully realize anticipated cost savings and other anticipated benefits of the merger when expected or at all; business disruptions from the proposed merger that will harm TSYS’ or Global Payments’ business, including current plans and operations; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the merger, including as it relates to TSYS’ or Global Payments’ ability to successfully renew existing client contracts on favorable terms or at all and obtain new clients; failing to comply with the applicable requirements of Visa, Mastercard or other payment networks or card schemes or changes in those requirements; the ability of TSYS or Global Payments to retain and hire key personnel; the diversion of management’s attention from ongoing business operations; uncertainty as to the long-term value of the common stock of Global Payments following the merger, including the dilution caused by Global Payments’ issuance of additional shares of its common stock in connection with the transaction; the continued availability of capital and financing following the merger; the business, economic and political conditions in the markets in which TSYS and Global Payments operate; the impact of new or changes in current laws, regulations, credit card association rules or other industry standards, including privacy and cybersecurity laws and regulations; and events beyond TSYS’ or Global Payments’ control, such as acts of terrorism.

Any forward-looking statements speak only as of the date of this communication or as of the date they were made, and neither TSYS nor Global Payments undertakes any obligation to update forward-looking statements. For a more detailed discussion of these factors, also see the information under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in TSYS’ and Global Payments’ most recent annual reports on Form 10-K for the year ended December 31, 2018, quarterly reports on Form 10-Q for the period ended March 31, 2019, and any material updates to these factors contained in any of TSYS’ and Global Payments’ future filings.

As for the forward-looking statements that relate to future financial results and other projections, actual results will be different due to the inherent uncertainties of estimates, forecasts and projections and may be better or worse than projected and such differences could be material.
