In a recent analysis, Fidelity National Information Services, Inc. (FIS) has received a renewed 'Outperform' rating from William Blair, a prominent research firm. The positive outlook is largely attributed to the company's ongoing operational enhancements and its significant $13.5 billion acquisition of Global Payments' Issuer Solutions business, formerly known as TSYS. Despite these strategic advancements, William Blair suggests that the market currently undervalues FIS's true potential.

William Blair Reaffirms Confidence in Fidelity National Information Services Amidst Growth Projections

On Wednesday, March 18, 2026, William Blair reiterated its 'Outperform' rating on Fidelity National Information Services, Inc. (NYSE:FIS), a leading financial technology company. This reaffirmation comes as the research firm updated its financial models to incorporate the full impact of FIS's recent $13.5 billion acquisition of Global Payments' Issuer Solutions business, finalized in January. This strategic move is expected to unlock substantial value for FIS.

William Blair's assessment highlights that FIS's current market valuation does not adequately account for the significant operational improvements implemented over the past few years, nor does it fully reflect the growth opportunities presented by the integration of the TSYS acquisition. The firm's updated projections reveal a robust financial trajectory for FIS. They anticipate the company's reported free cash flow to experience a notable increase, rising from $1.6 billion in 2025 to an estimated $2.1 billion in 2026, and further to $2.5 billion by 2027. This growth in free cash flow is a key indicator of the company's financial health and its ability to generate profits.

Beyond cash flow, William Blair also forecasts steady organic revenue growth for FIS, expecting an annual increase of approximately 4% to 5%. This organic growth, combined with modest margin expansion in the upcoming years, underscores the company's sustainable business model and its capacity to enhance profitability. Initially, FIS plans to allocate its free cash flow towards reducing its debt leverage, aiming to lower it from 3.4x to a more conservative 2.8x. In the longer term, the accumulated cash is expected to support future mergers and acquisitions, as well as share repurchase programs, further enhancing shareholder value.

Fidelity National Information Services, Inc. stands as a pivotal entity in the financial technology landscape, offering a comprehensive suite of services to financial institutions, businesses, and developers. Its expertise spans core banking systems, innovative digital banking solutions, and sophisticated wealth management platforms, positioning it at the forefront of financial innovation.

The sustained 'Outperform' rating from William Blair underscores the firm's confidence in FIS's strategic direction and its capacity for future growth. The integration of the TSYS acquisition, coupled with strong operational performance and prudent financial management, paints a promising picture for investors. While the market may currently overlook some of these positive developments, William Blair's analysis suggests a compelling investment case for Fidelity National Information Services, highlighting its potential for continued expansion and value creation in the dynamic fintech sector.

This renewed endorsement from William Blair provides a clear signal of the firm's strong belief in Fidelity National Information Services' trajectory. It emphasizes the importance of looking beyond immediate market perceptions to recognize the long-term strategic benefits and operational efficiencies that are set to drive the company's future success. For investors, this analysis offers a valuable perspective on a key player in the financial technology industry, suggesting that FIS is well-positioned for sustained growth and profitability.
