Why Adyen could be one of Europe's most undervalued fintech stocks
Adyen shares remain under pressure following one of the weakest periods in recent years. To resume a sustainable uptrend, the company needs stronger fundamental catalysts.
One potential catalyst could come from Mastercard. The payments giant is continuing to deepen its involvement in AI-powered payments. On Wednesday, Mastercard announced the launch of a new protocol designed to make it easier for AI agents to conduct transactions with one another.
Adyen is among the companies participating in the development of this new AI payment infrastructure.

Adyen shows early signs of a potential rebound
As noted in our previous analysis, Adyen shares recently fell to a new 52-week low and remain below a medium-term descending trendline.The stock failed to hold the psychological €800 level, although the €773 support zone continues to act as a significant support area.
From a technical perspective, Adyen needs to reclaim €800 and break above its trendline resistance (highlighted in yellow) to confirm a meaningful recovery. If that occurs, the stock is likely to test the €1,000–€1,100 zone.
Another important technical signal is the bullish divergence on the RSI (14), which has been forming since February of this year.
However, investors should remain cautious. A break below €773 would increase the probability of a decline toward €719, the gap-up level from November 2023.
Strong fundamentals continue to support Adyen
Despite intense competition from Stripe and PayPal, Adyen remains highly profitable. The company currently reports a profit margin of 44.71%, ROE of 22.33%, and ROA of 5.92%.These are exceptionally strong metrics for a payments company. Many fintech firms can demonstrate growth, but few can match Adyen's level of profitability.
The company's debt-to-equity ratio stands at just 4.78%, indicating an almost debt-free balance sheet. By comparison, PayPal carries significantly higher leverage. Adyen continues to finance much of its growth through internally generated capital.
Based on these metrics, Adyen's fundamentals currently appear significantly stronger than the market sentiment surrounding the stock.
