Distribution: All FIS employees

Dear Colleagues:

In January, we said our focus in 2019 is beingBOLD. Bold in our investments to transform our company and portfolio, bold in our ideas and bold in our actions that help our clients compete and win.

I am very pleased to announce that FIS has undertaken a bold move and signed a definitive agreement to acquireWorldpay, a global leader in payment technology solutions. This is a tremendous step forward in our drive to become a Top 100 company, bringing together two great companies with similar business models, complementary solutions and highly talented employees who are dedicated to serving the financial services industry and accelerating the future of finance and commerce.

As the No. 1 global acquirer of transactions, Worldpay is one of the world’s leading payment technology companies, with annual revenue of $3.9 billion. With an integrated technology platform, Worldpay provides payment solutions for financial institutions, retailers and businesses offering a comprehensive suite of payment products and services to more than one million merchant locations globally. The company processes over 40 billion transactions annually, supporting more than 300 payment types across more than 140 countries in over 120 currencies. I look forward to welcoming Worldpay’s more than 8,000 employees into our FIS family when the combination closes later in the year.

Creating a Bold New Payments Commerce Community

FIS and Worldpay lead our respective markets in modernization investments. Upon closing, our clients will have access to a wider portfolio of modern, digital assets that can help them accelerate growth, streamline operations and better engage with their customers.

The FIS and Worldpay payment solutions are very complementary. Upon closing, the addition of Worldpay will bring new solutions, services and talent that enhance our current client offerings including significant scale in merchant acquiring services. Specifically, our clients will benefit from greatly expanded merchant capabilities, as well as new acquiring and unified payment offerings. Worldpay’s strong business leaders and talented employees will bring valuable insights and experience to our global team.

The combined company will continue to operate under the FIS name and be headquartered in Jacksonville, Fla., and I will serve as chairman, president and CEO.Charles Drucker, current Worldpay executive chairman and CEO, will become executive vice chairman of our board of directors upon closing.

We will be streamlining and simplifying our organizational structure around financial institutions, capital markets and retail payments. Our Retail Payments business will operate under the Worldpay name.

Next Steps

The transaction is subject to regulatory and shareholder approvals and contractual closing conditions. We expect to close later in the year. Until then, it is business as usual for both companies and we must continue to focus on serving the needs of our clients. We cannot begin integration orgo-to-market planning until the transaction closes.

Attached is a copy of the news release we issued this morning about the transaction. I also encourage you to watch this briefvideo about the benefits this combination brings to all of us.

Over the next few days, you may have questions about this combination and how our teams will work together. The attached FAQ document will provide some additional information about Worldpay, the strategic rationale for the combination and next steps. Facts sheets for both FIS and Worldpay are also attached. I encourage you to talk with your manager or submit your unanswered questions tofis.corporate.communications@fisglobal.com. If you receive questions from clients, please direct them to their strategic account manager (SAM). All media inquiries should be directed tokim.snider@fisglobal.com, and investor inquiries should be directed topete.gunnlaugsson@fisglobal.com.

I hope you join me in celebrating this significant,BOLD milestone. Your hard work and focus on championing the needs of our clients has made this possible and continues to serve as an outstanding example of how we are empowering the financial world.

I have never been more excited about the future of FIS and look forward to what we will accomplish together.

Regards,
