Where is Fiserv headquartered?

Fiserv is headquartered at 600 N. Vel R. Phillips Avenue in downtown Milwaukee, Wisconsin. The company moved its headquarters from suburban Brookfield into the city in 2023.

Fiserv was formed in 1984 through the merger of two regional data processing firms, Sunshine State Systems of Tampa, Florida and First Data Processing of Milwaukee, Wisconsin. Leslie Muma and George Dalton built the combined company through a relentless acquisition strategy, buying more than 150 companies over the following three decades to consolidate the fragmented market for bank and credit union data processing.

Key milestones mark the roll-up era. The 1991 purchase of Information Technology Inc. for $55 million expanded credit union processing. The 2007 acquisition of CheckFree for about $4.4 billion made Fiserv the dominant provider of electronic bill payment in the United States. The company went public on Nasdaq in 1986 and spent most of its history listed there before moving to the NYSE in the 2000s and then returning to Nasdaq in 2025.

Frank Bisignano arrived as CEO in 2020 after the largest deal in company history: the January 2019 agreement to acquire First Data Corporation for $22 billion in stock. The merger closed in July 2019 and transformed Fiserv from a back-office processor into the largest merchant acquirer in the United States, bringing the Clover point-of-sale platform, the Carat enterprise commerce stack, and First Data's global acquiring network. KKR, First Data's former private equity owner, became Fiserv's largest single shareholder.

Under Bisignano, Fiserv rebranded in 2023, moved its headquarters from suburban Brookfield into downtown Milwaukee in 2023, and pushed Clover as its primary growth engine, with Clover revenue compounding at rates above 20%. Bisignano was confirmed as Commissioner of the Social Security Administration in May 2025, and president Mike Lyons, a former PNC executive who joined Fiserv in 2024, became CEO.

The Lyons tenure was dominated by a credibility crisis. Fiserv cut its 2025 organic revenue growth forecast in July 2025 and cut it again on October 29, revealing that prior guidance had relied on one-time revenue and an outsized contribution from Argentina. The stock lost roughly 42% in one session. Management overhauled the leadership team, launched the Elevate cost program targeting $1 billion of savings, and reset 2026 as a transition year. Results stabilized through 2026, with third quarter Clover gross payment volume up 11% excluding a gateway conversion. Lyons departed in June 2026 to lead Truist, and co-president Takis Georgakopoulos took over.

Fiserv publishes an annual corporate responsibility report covering data privacy, information security, workforce metrics, and environmental footprint. Material ESG issues for the company are cybersecurity and responsible data use rather than physical supply chains. The company discloses Scope 1 and 2 emissions and has invested in renewable energy credits for its data centers. It runs programs supporting minority-owned small businesses, including the Back2Business grant initiative launched in 2020. Fiserv is not a certified B Corporation.

Fiserv has appeared on the Fortune 500 and on Forbes' lists of America's best employers. Its Carat platform won Merchant Payments Ecosystem's Merchant Acquirer of the Year award at the 2022 MPE Awards in Berlin following its launch. Clover hardware has received design recognition, and the company regularly appears on IDC and Gartner rankings for core banking and merchant acquiring scale.

The dominant controversy is the 2025 guidance collapse. After cutting forecasts twice, management disclosed that reported growth had been flattered by non-recurring items and by high-inflation revenue from Argentina. Multiple securities class action lawsuits were filed in late 2025 and 2026 alleging the company misled investors about Clover's growth trajectory and the quality of its revenue. The suits were pending as of late 2026.

Fiserv also faces recurring criticism over the opacity of its adjusted metrics, which exclude large items including acquisition amortization and, in 2025, severance and restructuring costs tied to the Elevate program. Earlier controversies include a 2019 First Data-era disclosure that merchant processing agreements generated unexpected liabilities, and state-level data privacy actions common to large processors. The company acquired Payeezy-era First Data assets subject to older FTC consent requirements on data security following First Data's historical breaches.
