Fiserv (FISV)
Runs merchant commerce and financial technology across payments, banking, and card processing.

Fiserv is the plumbing under American card payments — the checkout systems in small shops, and the software behind bank accounts, debit cards and credit cards. The work is quiet, contracted, and repeats every month; no single line carries the company. After much of its recent growth turned out to come from prepaying merchants in high-inflation Argentina, targets were pulled, and a new chief executive is resetting promises and selling pieces.

Clover
The till-and-software system for small shops, and Fiserv's one real growth engine: $3.3B in FY2025, up 23%. Then it stalled — revenue grew 2% in mid-2026 and the full-year expectation was cut to around 5% growth.

In plain English
Walk into a sandwich shop and the small white screen on the counter taking your card is often a Clover. It is a cash register, a card reader and a small business-management kit in one machine: it takes the payment, tracks what sold, and runs the shop's day.
The merchant buys or rents the hardware, pays a monthly fee for the software, and pays a slice of every card sale. Banks and sales agents hand Fiserv the customers — dozens of the largest U.S. banks refer their small-business clients — so the machine arrives through a trusted introduction rather than a cold call. Add-on services beyond plain payments are now a quarter of what Clover earns.
Small Business outside Clover
The older merchant book — plain terminals, bank and agent portfolios, and Argentina — shrinking about 5% a year as Fiserv moves those shops onto Clover. The Argentine piece grew triple digits in 2023 and 2024 while local inflation and rates were soaring.

In plain English
The part being quietly folded away. Before Clover there were ordinary card terminals sold through banks, sales agents and software companies, plus a sizeable merchant business in Argentina. Those shops still pay their processing fees, and Fiserv still collects them while converting the ones it can onto Clover.
Argentina works differently. Shoppers there buy in instalments, so Fiserv hands merchants their money early and keeps a cut for the wait, borrowing to fund it. When Argentine inflation and interest rates run hot that cut swells and flatters the whole company's growth; when they cool it shrinks just as fast, which is exactly what clipped both revenue and profit in mid-2026.
Digital Payments
Debit processing for banks, two of the networks that carry a payment when a shopper types a code, and bank bill paying. It is sliding 5–6% a year. JPMorgan, Bank of America and others were reported in mid-2026 to have held early talks about buying a network.
Competes with Pulse debit network (Discover) · NYCE debit network (FIS) · Interlink debit routing (Visa)
In plain English
Two jobs, one customer: the bank. When a debit card is tapped, someone has to check the balance, send the payment down the right road and move the money — Fiserv does that for banks and credit unions across the country. It also owns two of the roads themselves, STAR and Accel, the ones used when a shopper types a code instead of signing.
Banks pay per transaction and per account, month after month. Two things pull against it: over half of U.S. debit traffic travels Visa's own road rather than Fiserv's, and the long-standing business of mailing out bill payments is shrinking faster than Zelle transfers, which Fiserv plugs banks into, are growing.
Issuing
The machinery behind banks' credit and prepaid cards — approving, recording, printing and mailing them. More than 1.7 billion accounts sit on it and still grew about 4%, while revenue fell against an unusually rich prior year.
Competes with TSYS issuer processing (FIS) · Marqeta card issuing (Marqeta) · i2c issuing platform (i2c)
In plain English
Every credit card in a wallet has a machine somewhere keeping its score: what was spent, what is owed, whether this purchase clears. Most banks would rather not build that machine, so Fiserv rents them one — and prints and posts the plastic too.
Each account pays a dollar or two a year at most, which sounds trivial until the accounts are counted: more than 1.7 billion of them, a base management says is nearly twice its closest rival's. The fees repeat for as long as the card exists, so growth means banks issuing more cards — and keeping the ones already there when contracts come up for renewal and rival platforms come calling.
Banking
The bookkeeping systems banks and credit unions run their accounts on — more than 4,000 U.S. institutions use a Fiserv one. Revenue is down and the institution count slipped about 3%, even as the accounts riding on those systems grew.

In plain English
Think of the ledger that knows your balance. Every bank needs one, it can never be wrong, and replacing it is like changing an aircraft's engine in flight — so banks buy one and stay for decades. Fiserv sells several: DNA, Premier, Signature and others, and it keeps supporting all of them rather than herding customers onto a single system.
The bank pays a running fee tied to accounts, plus more for the pieces bolted on — online banking, fraud checks, cheque processing, consultants. Unglamorous, and lately it leaks: bank mergers keep quietly removing customers, and the count of institutions on a Fiserv ledger has been falling.
Finxact
Fiserv's newer, internet-native bank ledger. Accounts on it grew over 75% in a year, and in August 2026 Flagstar — a bank with more than $80B of assets — picked it, dropping both an older Fiserv system and a rival's.
Competes with Vault core banking (Thought Machine) · Temenos cloud core (Temenos) · Modern Banking Platform (FIS)
In plain English
The new ledger sitting in the same building as the old ones. Finxact does the same job as Fiserv's long-serving bank systems — keeping every account's balance exactly right — but it was built to run over the internet and to let other companies' software plug straight into it, which is why it also ends up powering bank-style features inside companies that are not banks.
Banks pay to run on it month after month, same logic as before. The honest wrinkle: some wins come from banks walking off Fiserv's own older ledgers, and the money is still small enough that Fiserv does not report it on its own.
Commerce Hub and Carat
One payment system for very large companies — tills, apps, websites and kiosks in a single place. Revenue is roughly flat, transactions through it rose nearly 200% early in 2026, and slow switch-ons were the largest single piece of the mid-2026 cut to Fiserv's own forecasts.

In plain English
A burger chain with drive-throughs, an app, self-service kiosks and a website wants one place where all those payments land: the same fraud checks, the same refunds, one daily total. That single front door is Commerce Hub, and the wider system it belongs to is called Carat.
Customers like Yum! Brands and Blue Shield of California sign multi-year deals and pay per transaction, so the money is steady once it starts. Starting is the hard part — wiring up a giant company takes quarters, not weeks, and when the switch-on date slips the revenue slips with it. Stripe has meanwhile been growing its U.S. card volume fast, and the Worldpay–Global Payments merger created the country's largest card processor.
