Beyond the figures, a clear ambition: to become the sovereign champion of European digital. Ionos delivers a good copy in the first half of 2025, confirming the robustness of its economic model, the relevance of its sectoral strategy and the effectiveness of its execution. The digital future of the old continent could well be written in German capital letters.
Ionos Group loops the first half of 2025 on a high -flying economic performance. The turnover reaches 895 million euros, up +19.1 % over a year. Better still, the adjusted Ebitda jumped from +23.3 % to 268.7 million euros, an operating margin of 30.0 %, against 29.0 % a year earlier.

Digital Solutions & Cloud: the war machine continues to fuel
The group’s core business (the Digital Solutions & Cloud Division) generates 656 million euros in turnover on the semester, growing +7.0 % (or +7.4 % excluding interco income). This segment alone represents 73 % of consolidated turnover. It includes two sub-activity: productivity and web presence solutions (Web Presence & Productivity) and public/private cloud offers. The profitability of this pole impresses: 236.9 million euros in adjusted Ebitda, up +20.7 %, a margin of 36.1 %, against 32.0 %a year earlier. This improvement comes from both healthy organic growth and reinforced cost discipline. The dynamics remain particularly robust in Europe, where Ionic Displays dominant positions (n ° 1 or n ° 2 in six key markets), and captures around 130 million euros in annual income in North America.

Note: the Cloud Solutions branch only has 90 million euros in income (10 % of the total), in rapid growth. Ionic Indicates that this activity will be profitable within a year, with margins currently reinvested in growth.
Adtech: the risky bet that starts to pay
The Adtech segment (ex-Aftermarket), historically more volatile, is this time illustrated as a powerful growth engine. Its income exploded by +72.7 % over one year to 239 million euros in S1 2025 (against € 138.4 million in S1 2024). This performance, although starting from a weak base, reflects the success of an accelerated product transition, especially towards the RSOC model, which continues on the second half of the year. On the profitability side, the contrast remains strong: the margin of Ebitda reaches only 13.3 % on the semester, reflecting the low maturity of this segment. The perspectives are however positive. Management anticipates a stable turnover on the S2, leading to a total of 400 million euros over the year. In the medium term, Adtech’s new positioning could generate operational leverage growth relays.
A quarterly dynamic always as sustained
The second quarter confirms the ascending trajectory. Turnover is € 448.7 million, up +18.5 % compared to Q2 2024. The adjusted Ebitda increased by +22.8 % to € 137.7 million, for a margin of 30.7 %, in improvement of 110 base points. Performance is driven by Digital Solutions & Cloud, which reaches € 326.4 million in turnover (+6.7 %) with an EBITDA margin of 38 %, in strong increase. As for the Adtech, it recorded a spectacular leap of +68.3 % to € 122.3 million, even if its profitability remains behind (margin of 11.1 % vs. 12.8 % in T2 2024).
