FISV vs GPN: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
FISV and GPN are similarly sized, but GPN trades noticeably cheaper on forward earnings (5.22x vs 6.04x): the market is paying up for FISV's profile and pricing GPN more conservatively, or for faster growth. Which you prefer comes down to the drivers you believe, and whether adding either over-concentrates what you already own.
FISV vs GPN: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | FISV | GPN | What it tells you |
|---|---|---|---|
| Forward P/E | 6.04 | 5.22 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 9.14 | 30.91 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Price vs 52-week range | 7% of range | 78% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Reading it: GPN is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how FISV and GPN affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. FISV and GPN share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined FISV and GPN exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Fiserv (FISV) do?
Fiserv is one of the largest payments and financial-technology companies in the world. It operates broadly in two areas: merchant solutions, where it processes card and digital payments for millions of businesses and runs the Clover point-of-sale and small-business platform, and financial solutions, where it provides core account processing, card issuing, digital banking, and related technology to banks and credit unions. Most of its revenue is recurring and transaction-based, tied to the volume of payments and accounts it processes, which gives the business a steady, infrastructure-like quality. Fiserv changed its listing to the Nasdaq and reinstated its original ticker symbol FISV (from FI) in November 2025.
What does Global Payments (GPN) do?
Global Payments Inc. (NYSE: GPN) is one of the largest payment technology companies in the world, providing merchant acquiring, point-of-sale software, and commerce-enablement services to businesses ranging from small shops to global enterprises. On January 12, 2026 the company completed a transformative pair of transactions: it acquired Worldpay (net purchase price around $22.7 billion) from FIS and GTCR, and simultaneously divested its Issuer Solutions business to FIS for roughly $13.5 billion. The result is a pure-play merchant-commerce provider that, combined with Worldpay, processes more than 20% of U.S. payments volume, with strength in the middle market (businesses with roughly $1M to $100M in annual revenue) alongside enterprise and small-business channels.
FISV vs GPN: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- FISV drivers: Recurring, transaction-based revenue; Clover platform growth.
- GPN drivers: Worldpay integration and scale; Pure-play merchant focus and Genius platform.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The main risk is that Fiserv's growth is modest, so slowing organic revenue growth, margin pressure, or weaker free cash flow can disappoint investors, as the 2026 share weakness showed. For GPN, the Worldpay acquisition loaded the balance sheet with significant debt, raising integration and interest-cost risk in a period of elevated rates.
FISV or GPN: which should you pick?
FISV vs GPN: the full fundamentals
FISV. Figures are approximate and tied to the asOf date; verify live numbers before acting. Fiserv is a profitable, cash-generative company, so an earnings multiple is meaningful, and the 2026 share weakness left some valuation metrics looking discounted versus its history. But the market's concern is the pace of organic growth, margins, and free-cash-flow recovery, so investors should weigh those trends and execution on internal initiatives rather than the multiple alone.
GPN. GPN trades around $82 with a market cap near $22.5 billion, a low forward multiple of roughly 6x its ~$13.90 midpoint adjusted EPS guidance, reflecting skepticism about legacy-processor growth and Worldpay integration risk. Trailing GAAP P/E figures are distorted by the January 2026 transactions and a large discontinued-operations loss, so adjusted metrics are the cleaner lens. The 52-week range runs roughly $61 to $91.
Headline figures (approximate, Jul 2026): FISV shows revenue (q1 2026) ~$5.03 billion, down about 2% year over year, adjusted eps (q1 2026) ~$1.79, beating expectations though down year over year, gaap eps (q1 2026) ~$1.07, 2026 guidance organic revenue growth ~1% to 3%; adjusted EPS ~$8.00 to $8.30 (reaffirmed); GPN shows adjusted net revenue (q1 2026) ~$2.86B, adjusted eps (q1 2026) ~$2.96, fy2026 adjusted eps guidance ~$13.80-$14.00, market cap ~$22.5B.

FAQ
What is the difference between FISV and GPN?
+
Fiserv is one of the largest payments and financial-technology companies in the world. Global Payments Inc. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is FISV or GPN the better stock?
+

Which is cheaper, FISV or GPN?
+
On forward P/E (as of August 2026), FISV trades at 6.04x and GPN at 5.22x, so GPN is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both FISV and GPN?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of FISV vs GPN?
+
FISV: The main risk is that Fiserv's growth is modest, so slowing organic revenue growth, margin pressure, or weaker free cash flow can disappoint investors, as the 2026 share weakness showed. Execution risk around internal initiatives like Project Elevate is a real concern; if efficiency and growth improvements lag, sentiment can stay pressured. Competition is intense across both merchant acquiring and bank technology, from large processors and fast-growing fintechs alike, which can pressure pricing and share. Payment volumes are tied to consumer and business spending, so an economic slowdown would weigh on results. The bank-technology business depends on long sales cycles and the health of its financial-institution clients. Fiserv also carries debt from past acquisitions, so interest costs and integration matter. Regulatory changes in payments, interchange, and data handling add uncertainty. None of these threaten the franchise's core, but together they explain why a scaled leader can still see its stock struggle when growth and execution come into question. GPN: The Worldpay acquisition loaded the balance sheet with significant debt, raising integration and interest-cost risk in a period of elevated rates. GAAP results are noisy during the transition (Q1 2026 posted a large GAAP loss driven by discontinued operations even as adjusted EPS grew), which can obscure the underlying trend. Competitively, cloud-native platforms like Adyen and Stripe keep winning enterprise volume, Block dominates micro-merchants, and Fiserv remains a scaled direct rival, so pricing and share pressure are ongoing. Payment volumes are also cyclical and sensitive to consumer spending, and a failed or slow integration would undercut the entire pure-play thesis.
