Oct 29 (Reuters) - Dutch payments processor Adyen ADYEN.AS reported quarterly revenue ahead of market expectations on Wednesday, driven by more business from existing customers and strong retail activity that kept payment volumes high across all regions.
Third-quarter net revenue grew 23% from a year earlier on a constant currency basis to 598.4 million euros ($697.9 million). Analysts had expected 21.1% growth on average, according to a Visible Alpha consensus poll provided by Adyen.
