Ströer CEO Udo Müller Becomes Sole Leader
Ströer co-founder Udo Müller (63) is again leading the Cologne-based out-of-home advertising group alone as of early April 2026 after long-time co-CEO Christian Schmalzl (52) relinquished his mandate effective 31 March. Schmalzl had shared the boardroom with Müller for nine years and led operations since 2012; in January he announced he would not extend his contract beyond 2028. Ströer also announced that CFO Henning Gieseke (55) will leave the company on 4 June, with an advanced search underway for a successor who will additionally assume COO responsibilities. Müller, the founder and major shareholder, said the reorganised leadership and structure aim to accelerate Ströer's transformation into a platform business and exploit efficiency and margin opportunities from artificial intelligence.
Leadership consolidation and an executive reshuffle at a major Out‑of‑Home media sales house could influence the company's strategic direction (platform transformation, AI-driven efficiency) but is not industry‑shifting.

Ströer Soars in Revenue but Faces Image Crisis
Cologne-based media group Ströer reported a record 2025 revenue of €2.075 billion and an adjusted EBITDA of €626 million, surpassing prior company highs despite weak macroeconomic conditions. Management announced a strategic transformation toward an AI-driven platform business, with Co-CEO and founder Udo Müller saying the company sees significant efficiency potential over the next three to five years that should boost margins, capital efficiency, and free-cash-flow conversion. The positive financial results were overshadowed by internal controversy after an internal home-office announcement by Udo Müller angered employees and was later walked back, leaving a residual reputational dent.
