FIS vs GPN: Which Is the Better Buy in 2026?

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.

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.

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. FIS 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 FIS 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.

Fidelity National Information Services, Inc. is a global financial-technology company that provides the software and services banks, capital-markets firms, and merchants run on. It operates mainly through two segments, Banking Solutions (core processing, digital banking, payments, and related software for financial institutions) and Capital Market Solutions (trading, treasury, lending, and risk technology for buy-side and sell-side firms). FIS serves more than 20,000 clients across over 130 countries and processes trillions of dollars in transactions each year, which makes it more of an embedded infrastructure vendor than a consumer-facing brand. Because its software is woven into clients' daily operations, revenue is heavily recurring and switching costs are high.

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.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• FIS drivers: Sticky, recurring banking software; Capital Markets momentum.
• GPN drivers: Worldpay integration and scale; Pure-play merchant focus and Genius platform.

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 FIS is a mature, slower-growing business competing against strong rivals, so growth can disappoint if bank IT spending softens or clients delay projects. For GPN, the Worldpay acquisition loaded the balance sheet with significant debt, raising integration and interest-cost risk in a period of elevated rates.

Pick FIS if you believe its drivers more; GPN if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the FIS and GPN guides.

FIS. Figures are approximate and tied to the asOf date; verify live numbers before acting. The January 2026 close of the Issuer Solutions acquisition and Worldpay sale makes reported and pro forma growth figures diverge sharply, so read guidance carefully and check which basis a number uses. FIS trades as a mature, cash-generative software and payments company, so investors tend to weigh recurring-revenue durability, margin expansion, and deleveraging progress more than headline growth.

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): FIS shows revenue (ttm) ~$10 to 11 billion (2025 revenue was roughly $10.7 billion; segment mix shifts after the January 2026 Issuer Solutions and Worldpay transactions), 2026 revenue growth guidance ~mid-single-digit pro forma (roughly 5% to 6%), with much larger reported/adjusted growth reflecting the Issuer Solutions consolidation, adjusted ebitda margin ~high-30s percent, with guidance for continued margin expansion, market cap ~$20 billion (stock in the roughly $40 range in mid-2026); 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.

FIS and GPN are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined FIS and GPN exposure against your real portfolio. It is not an investment adviser.
