Gary Norcross
Chairman and Chief Executive Officer at Fidelity National Information Services
Thanks, Nate. Good morning, everyone, and thank you for joining us. Our second quarter results exceeded expectations across the board and demonstrates the continued success of our pivot to growth strategy that we laid out before the pandemic.
Revenue of $3.5 billion was the highest quarterly revenue in our company's history. Revenue increased more than $500 million or 17% year-over-year, and adjusted EPS grew 40%. Sales results, which were the strongest in our company's history, are being driven because our solutions remain in high demand, enabling businesses of all sizes to advance the way the world pays banks and invest.
This demand, combined with our organizational focus on delivering broader value to our clients, was also reflected in a very strong cross-sales, driving our largest revenue synergy quarter-to-date, increasing our run rate by 50% or $150 million sequentially to $450 million. This sales execution in turn drove a $1.5 billion increase to our backlog, which is now greater than $22 billion.
Our strong execution is driving us to raise both our 2021 guidance and increase our year-end revenue synergy target to $700 million. In addition, as we consider client demand across our portfolio of solutions, we are extending our mid-term outlook of 7% to 9% revenue growth through 2024.
I want to thank and recognize our colleagues around the globe for their continued hard work and dedication. They are our most important asset and play a vital role in advancing the commerce and financial technology that keeps thousands of clients up and running in the economy moving every day.
Turning to Slide 6. I'd like to highlight a few recent wins that demonstrate FIS' differentiation. Clients are increasingly demanding access to new capabilities that are outside of their traditional solution, so they can innovate in new and interesting ways. We have the unique ability to serve our clients horizontally across a breadth of financial technology with integrated cloud native platforms. Further, our open APIs are resilient and easy to use as clients expand their relationships with FIS.
Our sales success with the Modern Banking platform demonstrates this client demand as they look to differentiate with cloud native capabilities. This quarter, we delivered the largest release since the start of MBP, including expansion of commercial deposit functionality as well as new enhancements to our lending module.
As we have previously discussed, one of the exciting opportunities with the current MBP clients is an ongoing ability to cross-sell additional functionality modules. This quarter, we had our first cross-sell to American Express, who added a new checking account feature to their deployment. This is a great example of our ability to land large complex clients and the value of our modern platform.
As we continue to add functionality, clients continue adopting these new capabilities to grow their businesses, which drives additional revenue for FIS and expand these important relationships.
Fifth Third Bank provides a second key example of the ways we grow our strategic relationships. Fifth Third is a longtime client, who is on a journey to reengineer its technical infrastructure with a focus on resiliency and scale. This quarter, they expanded their relationship with us to replace their legacy in-house core with the Modern Banking platform and their legacy wealth management system with FIS Unity. Unity is our leading-edge global wealth management system and will provide rich data and insights for Fifth Third's customers throughout their wealth journey. It incorporates automated cash management, multicurrency and other advanced wealth management functionality and flexible design that is fully integrated with FIS Trust accounting.
T. Rowe Price provides yet another example of an industry leader looking to FIS to help them modernize their 401(k) retirement offering with advanced technology. This landmark win will lay the foundation for other large asset managers to utilize FIS as they look to leverage our scale and expertise in the retirement space.
In addition, PayPal and Chevron both expanded their relationships with us to begin utilizing our cloud-enabled payment switching capabilities. And finally, WesBanco joined our merchant referral network in order to upgrade to our leading acquiring technology.
As we continue to innovate, our integrated cloud native ecosystem creates a powerful network effect that empowers our clients to transform and grow. On Slide 7, I want to highlight another important win. I'm pleased to announce that Walmart will begin utilizing our innovative loyalty network, Premium Payback, for both in-store and e-commerce transactions. The value proposition for this solution is exceptional, driving positive outcomes for our merchants, issuers and the end consumer.
In other retail locations where we have rolled out the solution, we are seeing consumers accept premium paybacks offered to pay with points approximately 50% of the time when they are prompted. Both our merchant and our issuer clients are increasingly eager to participate, and we expect adoption to continue to ramp as we implement the solution with all the innovative clients shown on the slide as well as more in the future. Premium Payback is a clear example of the network effect that we've created by integrating, issuing and acquiring.
Turning to Slide 8. We invest heavily in new solutions and capabilities with the belief that the market is changing and how it consumes technology and looking for cloud-native architectures. The revenue contribution from solutions developed over the past three years continues to grow as a percent of our total revenue mix, up from less than 1% in 2019 to over 4% in 2021. This rapid growth is driven by our ability to cross-sell new solutions into our existing client base as well as adjacent verticals, which increases our total addressable market.
New solutions also contribute meaningfully to our total revenue growth, with contribution increasing from less than 1% in 2019 to more than 2% in total revenue growth in 2021. Looking forward, we expect new solutions to drive up to 3 points of incremental growth each year, supporting our outlook for 7% to 9% revenue growth through the midterm. At this point, a strong commitment to innovation is embedded in our culture and will continue to drive growth for years to come.
I will conclude my prepared remarks with Slide 9 before handing the call to Woody. We are at the forefront of the industry with the broadest collection of cloud-native solutions available. We remain uniquely positioned to serve domestic and multinational merchants who are looking for a single trusted provider for all of their acquiring needs. We solve our clients' most complex problems, ranging from global acquiring for their e-commerce business to treasury and cash management with our innovative Quantum software. Further, on the right side of the page, we show our unique bundle of cloud native solutions for financial institutions that demonstrate our ability to innovate at scale. Lastly, we highlight a few examples of innovative solutions that create compelling value propositions for both merchant and FIS clients in the center of the page.
Clearly, the investments we've made during the pandemic and driving differentiated outcomes for our clients and for us, and we continue to make these investments today in order to power future growth. It's why we are confident in our forward momentum to drive strong 7% to 9% revenue growth through 2024.
I'll now turn the call over to Woody to discuss our financial results and forward guidance. Woody?
