Fiserv, Inc.

Fiserv, Inc. is a global financial technology and payments company that combines core banking software with merchant acquiring services. For full-year 2025, the company reported GAAP revenue of $21.19 billion, adjusted revenue of $19.80 billion, and free cash flow of $4.44 billion. Its dual-segment model serves both financial institutions and merchants, positioning it as an integrated provider across the payments value chain.

Financial Solutions

The Financial Solutions segment provides core banking and debit card processing systems to nearly 10,000 financial institution clients, including banks and credit unions. Offerings include account processing, digital banking, payment processing, and related services delivered primarily under multi-year contracts. This segment generates recurring revenue and benefits from high client retention and integration with the company's debit networks.

Fiserv owns and operates the STAR and Accel debit networks in the United States, which provide transaction routing and network fee income. The company also maintains large mainframe disaster recovery centers in Nebraska, New Jersey, and Georgia, supporting the reliability requirements of its financial institution clients.

Merchant Solutions

The Merchant Solutions segment delivers payment acceptance and acquiring services to approximately 6 million merchant acceptance locations globally, with annualized processing volume of about $1.90 trillion. The segment serves small and mid-sized businesses primarily through the Clover platform and large enterprises through the Carat omnichannel commerce platform.

Clover generated $3.30 billion in revenue for 2025, an increase of 23%, with annualized gross payment volume of $329 billion. The platform integrates payment acceptance with employee scheduling, inventory management, and Clover Capital small business loans, which have grown at an annualized rate of 30%, increasing the share of non-transaction software value-added fees.

Strategic Acquisitions

Fiserv's transformation from a traditional financial outsourcing provider to a digital payments company has been driven by acquisitions, most notably the full integration of First Data, which created the current two-pillar structure of Financial Solutions and Merchant Solutions. This combination provides cross-selling opportunities between financial institution and merchant ecosystems.

In late 2025, Fiserv completed the acquisition of StoneCastle Cash Management, a cash management platform. The acquisition deepens the company's ties with thousands of partner banks for low-cost deposit liquidity allocation, adding a deposit-related capability to its financial institution relationships.

Scale and Operations

Fiserv employs approximately 42,000 people and operates 120 facilities worldwide, with business operations in more than 100 countries. The company's infrastructure includes self-built mainframe disaster recovery centers in Omaha, Nebraska, New Jersey, and Georgia, supporting mission-critical processing for financial institutions and merchants.

For 2025, GAAP diluted EPS was $6.34, an increase of 18%, alongside GAAP revenue growth of 4%. The company's scale in merchant processing and financial institution connectivity, combined with growing software and value-added service revenue, places it at 96/100 on the VerityRank composite score.
