Germany’s largest out-of-home media owner closed the 2025 financial year with record revenues of €2.075 billion and an adjusted EBITDA of €626 million, reaffirming its dominant market position. But beyond the record numbers, Ströer is signalling a reinvention: the evolution from an ad space marketer into a fully AI‑driven platform business.
Ströer: From OoH+ to AI Platform Business
In 2025, Out-of-Home (OoH) once again proved to be one of the most resilient segments of the German advertising landscape when market share rose to almost 10% – and Ströer’s 2025 earnings report reflected that resilience.
Ströer’s core OoH media segment set a new revenue record, generating €989 million. Digital out-of-home (DooH) contributed around €400 million, propelled by the ongoing digitization of premium locations. The highlight of the year was the launch of “The Whale” in Hamburg, Germany’s largest outdoor LED screen. Overall, DooH maintained a share of roughly 40% compared to static OoH.
The company’s total revenue also increased slightly: After surpassing the two-billion-euro mark for the first time in 2024, last year’s revenue rose to €2.075, with adjusted EBITDA reaching €626 million.
Although the figures are still preliminary and the final results will only be confirmed at the end of March, the strong momentum of the OoH market over the past year is clearly reflected in the performance of Germany’s largest outdoor advertising provider — despite the challenging economic environment.
Maximizing the value of existing assets
The most important development for Ströer is taking place behind the scenes. The company is (once again) looking to reinvent itself – this time with AI as the catalyst. Ströer believes AI can unlock additional value from its existing assets – the company already boasts deep customer relationships, extensive data sets, and one of Europe’s largest digital advertising networks with national reach.
But Ströer sees its future built around a platform logic: integrating previously siloed media products into an AI-orchestrated ecosystem. At the center of this strategy will be the upcoming Ströer Ad Manager, designed to automatically generate customized campaigns for both local SMEs and national advertisers. For planning and performance measurement, the AI-driven analytics suite Public Mind aims to introduce clearly defined KPIs to the OoH market, improving transparency and accountability.
In the local advertising segment, AI is expected to enable dynamic configuration of media products based on occasion, location, time, and budget. Campaigns could then be deployed either through self-service tools or via managed services. With around 50,000 existing local advertisers and more than three million SMEs in Germany as potential clients, the growth opportunity is considerable.
Ströer sees its future competitive advantage in enabling simple, goal‑oriented, and automated buying processes – an approach long established among Social Media players and now increasingly making its way into the physical public space.
Efficiency, yield management and a CTO for a new era
The shift to AI will also reshape Ströer’s internal processes. Smarter yield management promises more efficient utilization of digital inventory, while automation will drive higher productivity without proportionally increasing headcount. This shift is expected to boost margins, improve capital efficiency, and strengthen free cash flow over the next three to five years.
To accelerate the transformation, Ströer appointed Sven Scheffler as the Group’s first CTO, effective March 1, 2026. His mandate: build the technological backbone that turns Ströer’s media network into a scalable platform business anchored in AI.
