Jet Roos-van Aerssen steps down as Dutch national lottery CFRO
Roos-van Aerssen replaced Arjan Blok in the position in May of last year.
The Netherlands.- The Dutch national lottery Nederlandse Loterij has announced that Jet Roos-van Aerssen is stepping down from her position as chief financial and risk officer (CFRO).
Roos-van Aerssen had taken up the position in May 2024, succeeding Arjan Blok, when he was promoted as CEO of the Dutch Lottery. Before joining the state lottery operator, she worked in a range of international and national financial roles, including at Aegon, General Electric and Talpa Network.
Blok said in a statement: “Jet has made a significant impact on our organisation and our contribution to sports and exercise in the past year-and-a-half. We have come to know her as a professional and appreciate her commitment to the Dutch Lottery. We wish Jet every success in the future.”

Meanwhile, Nederlandse Loterij is seeking a new chair after Alexander Pechtold announced his decision to step down from the Supervisory Board from January 2026. The decision follows Pechtold’s appointment as the mayor of the southern city of Delft in a return to politics. Formerly leader of the D66 party, Pechtold has chaired the state lottery operator since April 2021.
The Nederlandse Loterij runs Staatsloterij, Lotto, and Eurojackpot. It has been focusing on modernsing both retail and digital platforms and emphasising responsible gambling practices. Recent appointments have included Claudia Sampaio as director of Retail and Yvonne de Liefde as head of sponsorships and Partnerships.
In May, the Dutch government announced that it had decided not to consider the privatisation of Nederlandse Loterij or land-based casino operator Holland Casino. While the government didn’t rule out privatisation in the future, it said such a move would not be “feasible and proportionate” at the current time.
The possible privatisation of the state gambling operations had been put forward at a parliamentary committee debate last November as the coalition government evaluated further reforms for the Dutch gambling market.
