The following is a transcript of a recorded message by Jeffrey S. Sloan, Chief Executive Officer of Global Payments Inc., made available to employees of Global Payments Inc. on May 28, 2019.

MR. SLOAN: Thanks for joining us today. I am delighted to talk to you about our agreement to merge with TSYS - one of the most significant transactions in the history of payments.

Before I get started, I do want to explain that because of the nature of the transaction and the approvals necessary for closing, we are not able to take questions regarding our announcement today.

This is a transformative and exciting day for the financial technology industry, and you should take pride in your hard work and dedication to our customers, which have enabled us to achieve this incredible milestone.

And to answer the question we get on just about every quarterly management call: At closing, we expect to indeed achieve our long sought after goal of Fortune 500 status, in advance of our year end 2019 objective.

For Global Payments, we view the combination with TSYS as the next logical step to accelerate our technology-enabled, software-driven strategy - the combined company will have a leading position in integrated payments, owned software in both merchant and issuing, increased scale in ecommerce and omnichannel solutions and further exposure to faster growth geographies.

It is core to our strategic initiatives to grow and control distribution, deliver innovative products and services globally, and leverage technology and operations as we create the preeminent technology-enabled payments company with extensive scale and unmatched global reach.

This combination presents tremendous opportunities for Global Payments:

• This partnership will accelerate our technology enabled, software driven strategy and diversify us into attractive and complementary businesses;

• It will significantly expand Global Payments’ direct distribution, small to mid-sized business or SMB customer base and vertical reach;

• The TSYS’ ecommerce and omnichannel business in the United States will substantially enhance Global Payments’ existing domestic business and provide numerous additional multinational opportunities for cross-sell internationally; and

• Global Payments will have exposure to some of the fastest growing digital payments trends through TSYS’ consumer solutions business.

As one company we will:

• Establish the leading pure play payments technology company.

• Process in excess of 50 billion transactions annually and serve nearly 3.5 million predominantly SMB merchant locations across more than 100 countries, with an unmatched salesforce of over 3,500 sales and sales support professionals worldwide.

• Provide owned software and payment solutions to more than 1,300 financial institutions worldwide, increasingly on a cloud basis.

• Have a leading position in integrated payments as TSYS’ exposure to more than 450 ISV partners across 50 plus vertical markets are highly complementary with OpenEdge’s 2,000 plus ISV partners in 70 plus vertical markets today.

• Benefit from TSYS’ payment facilitation technologies domestically.

• Create an extensive portfolio of distinctive products and services, which are highly complementary, resulting in significant cross-sell opportunities across our extensive existing customer base.

• And finally, significantly enhance our financial strength and flexibility with immediate investment grade credit ratings.

So I’m often asked what has changed at Global Payments over the past several years and how we have come to where we are today. First of all, it’s our people. Our people are our most important assets and our collective success is driven by the performance of our employees every day.

Second, we have made incredible strides to enhance our culture in terms of how we support our employees and how that directly impacts how we interact with our customers and support our communities.

In addition to advancing our strategic goals, TSYS, with its strong leadership and dedicated employees, will be a strong cultural fit that embodies our company’s brand of Service. Driven. Commerce. Our culture is a strong complement to TSYS’ People-Centered and Performance-Driven culture.

We have found the right partner to deliver significant value for our employees, customers, partners and shareholders.

Our common cultures will play a critical role in the success of this transaction. Each of us shares the view that our people come first, and that neither of our businesses would have achieved the successes that it has enjoyed without our dedicated employee base.

We look forward to taking the best of both of our cultures going forward and preserving and enhancing our commitments to the communities in which we live and work. In addition, as a combined company we expect to continue to invest significantly in training and development to provide further opportunities for current and future colleagues.

I understand the biggest question in everyone’s mind is “How does this impact me?” Some answers are:

• Global Payments and TSYS will continue to operate separately with business as usual until the transaction closes.

• We plan to capitalize on the best of both companies and cultures moving forward. As you can imagine, there is a great deal of work and coordination to do.

• Over the next several months integration plans will be developed and additional details will be communicated as appropriate after the closing date.

• The transaction, which is expected to close in the fourth quarter of 2019, is subject to the receipt of required regulatory approvals and other customary closing conditions and the approval of shareholders of both companies.

• As we move forward, we ask that you continue to focus on your day-to-day responsibilities, and on providing our customers with the industry-leading tech solutions and unparallelled service they have come to expect from us.

What I can tell you now, is that upon closing:

• The combined company will retain the name Global Payments and will have dual headquarters here in Atlanta and in Columbus, Georgia, where TSYS is currently located.

• I will become the combined company CEO at closing and remain a member of the board of directors

• Troy Woods, current CEO of TSYS, will become Chairman of the Board of Directors

• Cameron Bready will become President and Chief Operating Officer of the combined business

• Paul Todd, current CFO of TSYS, will become Chief Financial Officer

We couldn’t be more excited about the future as we bring together two industry leaders with strong businesses and cultures that will generate significant opportunities for our employees, customers, partners and shareholders worldwide.

The combined company will have a powerful culture with the very best people, providing the very best experiences for our customers with the very best technologies in the very best markets.

I look forward to keeping you informed of our progress.

Thank you for all you do for us every day.
