Exhibit 99.3

August 12, 2015

Distribution: All FIS employees

Dear Colleagues:

In a significant step toward our goal of continually reinventing FIS so that we remain industry leaders, I am pleased to announce that FIS has signed a definitive agreement to acquire SunGard a financial services leader in banking, capital markets and asset management solutions. This is a tremendous milestone bringing together two great technology companies with similar business models, complementary solutions and highly talented employees that are dedicated to serving the financial services industry. I am very excited to share this significant news with you today and look forward to welcoming SunGard’s 13,000 employees into our FIS family when the acquisition closes during the fourth quarter.

Upon closing, FIS will be uniquely positioned to offer clients a broad range of solutions for enterprise banking, capital markets, asset and wealth management, risk and compliance, treasury and insurance. Combined, our focus will be on servicing global, regional and community financial institutions as well as private equity, asset managers and insurance companies. Earlier this morning we announced this transaction to the market. I have attached a copy of the news release for your reference. Additionally, I also encourage you to watch this brief video about the benefits this combination brings to all of us.

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.

The FIS and SunGard solutions are very complementary. After the close, the addition of SunGard will bring new solutions and services that enhance our offerings including treasury, risk management, asset management, derivatives, trading and insurance. SunGard’s strong business leaders will bring valuable insights and experience to our global leadership team.

The combined company will be headquartered in Jacksonville, Fla. and I will serve as president and CEO. We will operate under the FIS name.

The transaction is subject to regulatory approvals and contractual closing conditions. We expect to close during the fourth quarter. Until then, it is business as usual for both companies and we must continue to focus on serving the needs of our clients.

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 SunGard, the strategic rationale for the acquisition and next steps. While we cannot begin integration or perform any go-to-market planning until we close, we encourage you to talk with your manager or submit your questions to fis.corporate.communications@fisglobal.com. If you receive questions from clients, please direct them to their strategic account manager (SAM) or global client partner (GCP). All media inquiries should be directed to kim.snider@fisglobal.com and investor inquiries should be directed to pete.gunlauggson@fisglobal.com.

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

Regards,
