Payment processor Adyen's stocks plummet after trade war growth warning

Adyen’s share price plummeted by 18 percent at the opening of the AEX on Thursday morning after the payment processor shared its half-year results with shareholders. Adyen recorded significantly slower growth than usual over the past six months, partly because some of its customers were heavily affected by the trade tariffs America imposed on other countries in April, NOS reports.

The 18 percent plummet at opening drew the entire AEX index down by 0.7 percent. Adyen's stock price showed a slight rebound, trading at 1,222.40 euros per share at 10:35 a.m.. Adyen is considered a growth giant on the Amsterdam Stock Exchange, and the impact of the looming trade war on the Dutch company shocked investors.

In the first six months of this year, Adyen processed €649 billion in payments, only 5 percent more than in the same period last year, the company told shareholders in a letter on Thursday. The company said that the small growth is mainly due to problems with one major customer, without disclosing who that customer is or the nature of the problems.

The company said that changes in United States trade tariffs have particularly affected online sales. The trade tariffs imposed by U.S. president Donald Trump are affecting many of Adyen’s major clients, especially Asian customers like Shein and Temu. Adyen is, therefore, more pessimistic about its growth prospects for this year. Earlier, the payment processor predicted faster growth in 2025 than last year, but now calls this “unlikely” due to global trade tensions.

Adyen added that it also sees opportunities in the trade war. “While the full impact of the tariffs is still unfolding, the pattern is clear: in times of change, companies turn to partners who offer both speed and resilience,” the company wrote, according to NOS. Because Adyen holds its own banking licenses, including in the United States and the United Kingdom, it can process payments faster than competitors that do not.

In the coming period, Adyen will focus on “deepening relationships” with current clients by detecting fraud more quickly and offering new services. Adyen’s current clients include big names like Facebook parent Meta, Uber, H&M, eBay, and Microsoft.

In the first half of this year, Adyen booked almost €1.1 billion in profit, 21 percent more than the same period last year. The company hired 223 new employees, bringing its total workforce to 4,500 people worldwide.
