Adyen N.V. announced that Ethan Tandowsky will step down from his role as Chief Financial Officer, with his resignation taking effect on Aug. 31, 2026. The company said Tandowsky is leaving to pursue an opportunity outside the fintech sector.
Tandowsky joined Adyen in 2016 and was appointed to the CFO position in 2023. During nearly a decade with the company, he was described as a core member of the leadership team who managed the firm’s global finance operations during periods of significant growth.
In response to the departure, Adyen’s Supervisory Board said it will commence a comprehensive search to identify a successor. The firm indicated it will provide updates on the recruitment process in due course.
Co-CEOs Pieter van der Does and Ingo Uytdehaage commented on the announcement, saying: "Ethan has been a constant part of the Adyen journey for nearly a decade. We regret his decision but value his contribution and his trusted partnership on the executive team."
Piero Overmars, Chair of Adyen’s Supervisory Board, added that the timing of Tandowsky’s decision was surprising, but that the board respects his choice to take on a new challenge and wishes him well.
"My time at Adyen has been incredibly rewarding," Tandowsky said. "I am proud of our shared achievements, the financial foundation we have built, and I have absolute confidence in Adyen’s future. As I make a personal decision to step outside of fintech to pursue a completely new path, my priority is ensuring a smooth transition and continued momentum over the coming months."
Following the announcement, Adyen’s shares fell 3% in over-the-counter trading. The company reiterated that it will update the market as the search for a new CFO progresses.
The departure closes a chapter that began in 2016 and saw Tandowsky assume formal responsibility for the company’s finance function in 2023. Adyen’s statements emphasize continuity and a planned transition, while the Supervisory Board has taken responsibility for finding his replacement.
