Exhibit 99.5

August 12, 2015

Dear Valued Client:

I hope you have heard the exciting news that FIS™ has signed a definitive agreement to acquire SunGard. This is a tremendous milestone bringing together two great companies with complementary solutions, highly talented employees that are dedicated to serving the financial services industry and similar business models. Combined, our focus will be on servicing global, regional and community financial institutions as well as private equity, asset managers and insurance companies. Most importantly, we believe this acquisition presents significant opportunities for our clients as we will be uniquely positioned to offer you a broad range of solutions for enterprise banking, capital markets, asset management, risk and compliance, treasury and insurance once the transaction is final.

The combination expands our ability to serve you, providing a broader set of technology and service offerings to enable you to serve your clients and grow in the markets you serve. The combined organization will be headquartered in Jacksonville, Fla. and I will serve as president and chief executive officer. It will operate under the FIS name.

A privately held company, SunGard is one of the world’s leading financial software companies, with annual revenue of $2.8 billion. The company provides solutions for approximately 14,000 clients in the financial services, insurance, public sector and education industries in more than 100 countries across the world. Its software solutions are delivered as a service or through on premise deployments and are surrounded by an extensive suite of service offerings.

We understand that it is your continued support and loyalty that determines our ultimate success. The FIS and SunGard solutions are very complementary. Upon close, we believe the combination will enable us to deepen our relationship with you in a more meaningful way.

The transaction is subject to all regulatory approvals and contractual closing conditions, and we expect the transaction to close during the fourth quarter. Until closing, we will continue to conduct business as usual as separate companies and will focus on serving the needs of all our clients. We are limited in the information we can share with you until the transaction closes and look forward to discussing additional details with you at the appropriate time.

As always, we thank you for your continued business and confidence in our organization.

Regards,

Gary Norcross

FIS President and CEO
