# Fiserv: Business Model & Revenue Engine

## Direct Answer

Fiserv reports revenue across 2 business segments in its fiscal 2025 Form 10-K. Merchant Solutions is the largest, with $10.1 billion of revenue (48% of the total), followed by Financial Solutions at $9.7 billion (46%).

## How Does Fiserv Make Money?

No single line supplies a majority of revenue: the largest, Merchant Solutions, is 48%, which spreads Fiserv's exposure across several demand drivers. Between fiscal 2024 and 2025, Merchant Solutions grew fastest (+5.3%) and Financial Solutions slowest (+2.0%), so the revenue mix tilts toward Merchant Solutions while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Merchant Solutions | $10.1 billion | $9.6 billion | 47.8% | 5.3% |
| Financial Solutions | $9.7 billion | $9.5 billion | 45.6% | 2.0% |

## Which Fiserv Segments Earn the Most?

| Segment | FY2025 segment operating income | Segment margin |
| --- | --- | --- |
| Merchant Solutions | $3.5 billion | 34.5% |
| Financial Solutions | $4.4 billion | 45.3% |

Segment operating income is the profit measure Fiserv reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within Fiserv more safely than against another company.

## What Does Fiserv Sell?

Fiserv also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Processing and Services | $16.9 billion | $16.6 billion | 79.6% | 1.5% |
| Product | $4.3 billion | $3.8 billion | 20.4% | 13.0% |

## What the Segment Figures Do Not Show

The rows above add up to 93% of Fiserv's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value Fiserv reported in the segment note and revenue disclosures of its Form 10-K filed February 19, 2026 (accession 0000798354-26-000009), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
