Adyen N.V. ADYEY

Key data

The business

Adyen is one platform, built in-house, that runs the whole payment chain: the checkout page, the fraud screening, the wiring into Visa and Mastercard, the settlement into a bank, and increasingly the issuing of cards and the holding of merchant money. It sells to large enterprises, not corner shops, and charges a thin fee on every euro processed plus a fixed sliver per transaction. Net revenue is what is left after paying the card networks, and that is the only top line worth watching. The moat is the single global code base: a merchant that runs online, in-app and in a physical store on Adyen gets one integration and one view of its customer, which is why volume tends to pool onto it rather than leak away. The concrete version is that the tap on the Spotify app and the terminal in a partner store can settle down the same rails. The 2023 wobble, when Adyen over-hired and its margins cracked, is the reminder that this is still a company that has to grow into its cost base rather than the other way around.

The numbers

Adyen reports only twice a year, so the honest read is a half against the same half a year earlier. The vendor's year-over-year growth fields still compare against the wrong period because of a reporting-basis break, so I use like halves only, and on that basis the story is a clear deceleration.

Earnings beat modestly three halves out of four, but the growth engine cooled: profit per share rose 27% in H2 2025 against its year-earlier half, then only about 12% in H1 2026 against its year-earlier half. Same beat, slower base.

The margins are genuinely rare, and the balance sheet is close to unbreakable: almost no debt, cash many times EBITDA, and stock-based pay near zero as a share of revenue, so reported profit and the profit an owner actually keeps are nearly the same number, which is not true of most software. The one soft spot is that free cash flow converts at only about 17% while EBITDA margin reads 57%; some of the reported profit is interest earned on merchant float, whose exact size was not pulled this run and which falls when the ECB cuts rates. Consensus has net revenue reaching about $4.1B by FY2028, which at held margins compounds earnings in the low-to-mid twenties and drops the multiple from 29 times to about 18. What the market seems not to believe, and what I do, is that ≈20% net-revenue growth is durable rather than fading to peer pace; the print that settles it is next half's net-revenue growth against that ≈18% bar.

Management

Adyen is still founder-shaped, co-founded by Pieter van der Does in 2006 and run without ever raising money after its 2018 listing, which is why there is no debt and no buyback habit to judge. There were no US-visible insider buys or sales in the last twelve months, but Adyen is a Dutch filer, so the absence of Form 4 activity is noise, not signal, and plan status is not disclosed. The tell that matters is the negligible stock-based compensation: management does not pay itself in dilution, and share count has crept up only slightly over three years. Executive compensation detail and the proxy were not pulled this run.

How it fails or surprises you

Big merchants consolidate onto one platform (right tail). If unified commerce and Adyen's newer financial products keep pulling a larger share of each giant customer's volume, net-revenue growth reaccelerates back toward 25%. The market is paying for deceleration, so a single half printing growth above 20% would force a re-rate off a multiple already near a decade low.

Growth settles at peer pace and the multiple follows. If net-revenue growth slips toward 15% for two straight halves, the market stops treating Adyen as a compounder and drags its 29 times down toward the peer 22 times, a de-rate that stacks on top of slower earnings. Watch the half-over-half net-revenue line, not EPS.

The earnings are better than the cash. Free cash flow converts at about 17% against a 57% EBITDA margin, and per-share growth already halved to 12%. If the gap is float income rather than operating cash, falling euro rates quietly shrink profit even as processed volume grows, and that is the fact the case for owning it explains least well.

Closing thoughts

The market has already done the hard part of the repricing, taking Adyen from a 60-times hyper-growth story to a 29-times maturing one, so the remaining edge is narrow and specific: whether ≈20% net-revenue growth is durable or quietly fading. That is resolved by a print, next half's net-revenue growth against roughly 18%, not by argument. The fatter tail looks like the upside, because the compression has mostly happened, the balance sheet removes any risk of permanent loss, and the owner keeps almost all of the reported profit. What is genuinely at risk if growth breaks to 15% is a further grind down toward peer multiples; what the upside is worth if growth holds above 20% is both the compounding and a re-rating off a low base.

The bet is still that Adyen keeps running the payments for the world's biggest online companies and keeps winning a bigger slice of what each one spends as they move more of their checkout onto Adyen's single system. It breaks if net-revenue growth slips under 15% for two consecutive halves while the float-driven part of profit thins with rates. The one pair to watch is half-over-half net-revenue growth against the take rate on processed volume; if both roll over together, the 29-times multiple was still too high.
