FLYW vs WU: 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: WU 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. FLYW and WU 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 FLYW and WU 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.

Flywire Corporation operates a global payments-enablement platform built for complex, high-value transactions that traditional card rails handle poorly. It serves four main verticals: Education (tuition and fees for universities worldwide), Healthcare (patient and provider payments), Travel (hotels and travel operators), and B2B (cross-border supplier and invoice payments). Flywire makes money primarily by taking a percentage fee on the payment volume that flows across its proprietary network, with additional revenue from vertical software and platform services such as billing, accounts receivable, and reconciliation tools. Because it controls both the money movement and the software around it, clients tend to stay, and Flywire captures more of each transaction than a pure processor would.

Western Union moves money across borders for consumers and businesses through a hybrid model: a vast physical agent network (retail locations in more than 200 countries and territories) alongside a growing Branded Digital app and wallet business. Its core Consumer Money Transfer segment still generates most revenue, while a faster-growing Consumer Services arm (bill payment, travel money, foreign exchange, and digital wallets like the newer V Go product) is being built out to diversify away from cash transfers. Full-year 2025 revenue was about $4.1 billion, down roughly 4% reported, as pricing and volume pressure in key corridors weighed on the legacy business.

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

• FLYW drivers: Vertical payments network with a take rate; Software makes it sticky.
• WU drivers: Signs of stabilization in the core; Digital and Consumer Services growth.

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: Flywire is exposed to immigration and student-visa policy, and management flagged roughly $30 million of potential 2026 revenue pressure from visa caps and tighter rules in the United States, Canada, and Australia that reduce international student flows; education has been its biggest vertical, so this is a real headwind. For WU, the central risk is competitive share loss: Wise and Remitly have overtaken or approached Western Union's transfer volumes with lower-cost, more transparent digital models, eroding its highest-margin physical business.

Pick FLYW if you believe its drivers more; WU 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 FLYW and WU guides.

FLYW. A payments-and-software company like Flywire is usually read on payment volume, take rate, adjusted gross profit, and adjusted EBITDA margin rather than on headline revenue alone, because the fee earned per dollar of volume and the software attach drive the economics. Flywire trades at a rich earnings multiple, with a price-to-earnings ratio well above payment-industry peers in mid-2026, which means the market is pricing in continued high-teens-to-twenties revenue growth and expanding margins. There is no pending acquisition of Flywire, so the shares are valued as a standalone growth fintech, not as a merger-arbitrage situation; a deal would only become relevant if one were actually announced.

WU. Western Union trades at deep-value multiples (price/sales near 0.6x) that reflect years of revenue erosion and margin compression rather than growth optimism. The very high dividend yield is a defining feature and a debate point: it rewards income holders but also signals market doubt about the durability of earnings. Full-year 2025 revenue was about $4.1 billion with GAAP EPS of roughly $1.52.

Headline figures (approximate, FY2025 results (year ended December 2025) and Q4 2025): FLYW shows revenue (fy2025) ~$623 million (+27% YoY), total payment volume ~$37.6 billion (+26%), adjusted ebitda ~$120.6 million (~20% margin), gaap net income ~$13.5 million (vs ~$2.9M in 2024); WU shows revenue (ttm) ~$4.1B, market cap ~$2.4B, trailing p/e ~6x, forward p/e ~5x.

FLYW and WU 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.
