Sedo’s revenue remained strong in Q4, IONOS hopes to sell unit by end of Q3.

Domain registration and hosting company IONOS (Frankfurt: IOS) reported its full-year 2025 financial results today.
The company, which owns 1&1, InterNetX, and other domain registrars, reported topline revenue growth of 5.5% for the year, with revenue increasing to €1,316.9 million.
However, that growth excludes the company’s Sedo subsidiary. After Google sunset AdSense for Domains, IONOS put Sedo up for sale, allowing it to remove its results from the topline financials.
Sedo’s overall revenue for 2025 was €291.5 million, down from €312.2 million the year before.
The real damage from Google’s change hit domain monetization companies in Q4, but Sedo seems to have held up fairly well as a business. To be sure, according to IONOS’ after-tax calculations, it swung to a loss of about €1.7 million for the quarter. But it seems like it could have been much worse, and its Q4 revenue of €72.9 million was about a quarter of the company’s full-year revenue.
IONOS continues to try to sell Sedo and hopes to wrap up a transaction by Q3 of this year.
