Ströer bets its future on AI after flat 2025

Ströer SE & Co. KGaA on March 5 reported record consolidated revenue of €2.08 billion for fiscal year 2025, a 1% year-over-year increase, while simultaneously announcing plans to transform itself from an advertising space marketer into an AI-driven platform business. The Cologne-based media company, listed on Germany's MDAX, disclosed the preliminary and unaudited figures alongside a strategic pivot that its co-CEO and founder Udo Müller described as something he had envisioned for years but could not execute until recent advances in artificial intelligence made it feasible.

The financial results tell a story of stability under pressure rather than momentum. Reported revenue rose to €2,075.1 million from €2,046.8 million in the prior year, but organic growth - which strips out acquisitions and currency effects - came in at negative 0.4%, a sharp reversal from the 6.4% organic growth posted in fiscal 2024. Adjusted EBITDA held essentially flat at €625.9 million, up marginally from €625.5 million. Adjusted net income declined 3% to €165.2 million. Free cash flow adjusted dropped 32% to €106.7 million from €157.9 million the prior year. Capital expenditures stayed stable at €93.3 million.

The fourth quarter offered more encouraging signals. Q4 revenue reached €603.3 million, up 3% from €586.0 million in the year-earlier period. Adjusted EBITDA for the quarter rose 3% to €212.3 million, while adjusted net income improved 5% to €78.9 million. Free cash flow adjusted in Q4 was €87.6 million, above the prior year's €79.6 million. These numbers suggest the business stabilized after what management acknowledged was a difficult first nine months.

Yet the financial results were not the headline. The centerpiece of the March 5 announcement was a strategic transformation built around two new AI-powered tools: the Ströer Ad Manager and Public Mind. Together, according to the company, these platforms will convert what has been a largely manual, silo-based sales operation into an automated, data-driven platform capable of serving far more customers at lower marginal cost.

What the Ströer Ad Manager actually is

The existing Ströer business operates through what the company itself describes as separate product worlds. Out-of-home, digital out-of-home, and digital ads have been technically and organizationally combined but marketed independently. Customers purchase pre-defined ad-space packages and build media plans on their own. The booking process is heavily manual. Campaign impact measurement relies on data drawn from different systems with different timelines.

The Ströer Ad Manager is designed to replace this model with a transaction and automation engine. According to the company's presentation materials, the platform will use AI to generate tailored customer products automatically based on budget, occasion, product category, industry, and location. Instead of pre-configured packages, the system would create bespoke advertising solutions for each customer and make them bookable through a one-click workflow.

The technical architecture involves six to seven AI agents working within a framework that includes guardrails, an evaluation framework, and prompt regression tests. A dynamic yield and rules engine would continuously optimize pricing and bidding rules. Review, booking, delivery, and billing processes would be automated end-to-end.

The company laid out a five-milestone development timeline. The concept and MVP phase runs from Q2 to Q3 2026. Deep data pipelines - including ETL connections, data cleanup, warehouse schema, product catalogue, and price engine - are scheduled for Q2 through Q4 2026. The agentic AI layer is targeted for Q3 2026 through Q2 2027. Sales UI, CRM integration, and reporting dashboards span Q2 2026 to Q3 2027. Testing and rollout, including internal pilots and performance tuning, are planned from Q3 2026 through Q4 2027.

During the earnings call, Müller was notably direct about costs. He told analysts the total investment for the Ströer Ad Manager is expected at "maximum around €2 million" in capital expenditure. "Due to the recent technological developments, it's much cheaper," he said. The low price tag reflects a fundamental shift in how software gets built: the company is layering use cases on top of existing large language model technology rather than building proprietary systems from scratch. Müller drew a contrast with the company's earlier investment of €50-60 million over time to develop its proprietary supply-side platform.

Public Mind: measuring what OOH campaigns actually do

The second pillar, Public Mind, addresses a persistent weakness in out-of-home advertising: the difficulty of proving campaign impact beyond contact numbers and reach. Public Mind is conceived as a predictive intelligence layer that uses AI and large volumes of mobility and behavioral data to make campaign impact predictable, measurable, and plannable.

The system introduces five core quality and performance indicators, or QPIs: Presence Density Index (PDI), Bottleneck Coverage Share (BCS), Lagged Location Lift (3L), Carryover Half-Life (CHL), and incremental Return on Ad Spend (iROAS). These metrics are designed to quantify campaign effectiveness in ways that go beyond traditional contact and reach measurement.

Müller framed the challenge with a football analogy during the earnings call. He compared the current state of OOH measurement to crediting all goals to the striker while ignoring the midfield that created the opportunities. Performance marketing platforms, he argued, claim credit through last-click attribution while offering no transparency about the broader brand-building work that made conversions cheaper. Public Mind aims to fill that gap by providing OOH-specific impact metrics comparable to what digital performance platforms already offer.

The development timeline is longer than the Ad Manager's. A proof-of-concept phase validating core QPIs with selected partners runs from Q2 to Q4 2026. MVP development with all five indicators spans Q1 to Q2 2027. Multi-partner testing and scientific validation is scheduled for Q3 to Q4 2027. Full enterprise rollout, including international expansion, is targeted for 2028 onward.

Unlike the Ad Manager, which is a Ströer-proprietary development, Public Mind is intended to become an industry-wide initiative. Müller said the company is in discussions with major industry players, and development costs are also estimated at around €2 million. "We are developing it right now, and we are almost finished with the first phase," he noted.

The OOH segment: growth despite a weak German ad market

Ströer's core OOH Media segment generated record revenue of €988.9 million in fiscal 2025, up 3.7% year-over-year. Traditional OOH revenue grew 1.7% to €536.4 million, while digital out-of-home was the primary growth engine, rising 7.9% to €398.2 million. Programmatic DOOH recorded renewed double-digit growth of approximately 12%, reaching €151 million. DOOH now accounts for more than 40% of OOH revenue.

Adjusted EBITDA for the segment rose 4.8% to €469.7 million, with the adjusted EBITDA margin improving half a percentage point to 47.5%. On a cash EBITDA basis - excluding IFRS 16 lease accounting effects - the segment posted a 10.9% compound annual growth rate in cash contribution since 2022, reaching €209.7 million. Out-of-home advertising gained further market share in Germany, reaching a record 10.0% of the overall advertising market.

The broader programmatic DOOH infrastructure has been expanding rapidly. Place Exchange launched programmatic guaranteed for DOOH within Google's Display & Video 360 in December 2025, enabling advertisers to secure premium inventory with predetermined pricing. Broadsign enabled advance DOOH booking through StackAdapt in November 2025, introducing programmatic guaranteed transactions to North American markets. Ströer itself implemented The Trade Desk's Price Discovery and Provisioning API in February 2026, alongside Virtual Minds and YOC, enabling automated deal configuration across its supply-side platform.

Research published in October 2025 found that out-of-home advertising achieves a marginal ROI of $7.58 per incremental dollar invested, substantially above the average media type marginal ROI of $5.52, despite OOH accounting for less than 1% of total media spending. Industry forecasters at WPP project that digital out-of-home will represent 41% of the $52 billion global OOH market in 2025, reaching $31.4 billion by 2030.

Ströer's move to build an AI-powered platform for OOH sales reflects an industry trajectory that billups CTO Shawn Spooner predicted in December 2025, when he argued that AI would drive a creative and operational transformation in out-of-home during 2026, not through automated content generation but by making planning, targeting, and measurement dramatically more efficient.

Digital & Dialog Media: stabilization with acquisition support

The Digital & Dialog Media segment posted revenue of €891.7 million, up 1.5% year-over-year. The Digital sub-segment, which includes online advertising and t-online content, saw revenue decline 2.4% to €441.9 million. Dialog, encompassing call centers and door-to-door services, grew 5.8% to €449.8 million.

Q4 was notably stronger. Segment revenue jumped 9% to €269.6 million, though the bulk of that growth came from the AMEVIDA call center acquisition, which contributed approximately €20 million in Q4 revenue. Organic growth for the segment in Q4 was 0.7%, an improvement after the first nine months. Full-year adjusted EBITDA for the segment fell 6.5% to €149.8 million, with the margin declining 1.4 percentage points to 16.8%.

CFO Henning Gieseke provided additional detail on the call center transaction. AMEVIDA was acquired during insolvency proceedings for a negligible purchase price. The company now operates from Ströer's existing overhead infrastructure, with optimized locations and renegotiated leases. For fiscal 2026, Ströer expects AMEVIDA to employ more than 1,200 additional full-time equivalents, generate more than €70 million in revenue, and contribute a high single-digit million euro amount to EBITDA.

t-online: defying the AI traffic squeeze

One of the more striking data points in the presentation concerned t-online, Ströer's flagship news portal. Despite Google's AI Overviews having been fully rolled out in the first half of 2025, t-online's page views in January 2026 were 10% higher than January 2024 levels. February 2026 showed a 13% increase compared with February 2024.

This resilience is notable given the documented impact of AI Overviews on publisher traffic more broadly. Research from Ahrefs published in February 2026 found that AI Overviews now correlate with a 58% reduction in click-through rates for top-ranking pages, up from 34.5% in April 2025. News publishers lost half their Google search traffic in two years, with traditional web search dropping from 51% of traffic in 2023 to 27% in Q4 2025.

According to Ströer's presentation, t-online reaches 29.33 million unique online users and 47 million total unique users when public video is included. The portal claims 43% reach among German-speaking adults aged 14 and older, outperforming Focus Online, Bild, and Der Spiegel. Ströer attributes t-online's durability to a high share of direct traffic, which reduces dependency on search engine referrals, and to the platform's three distribution channels: desktop, mobile, and DOOH public video screens. The company estimates that showing branded t-online content across its digital out-of-home network generates the equivalent of hundreds of millions in brand advertising value annually.

The t-online trust score of 50, measured by the Media Brand Trust Monitor, compares favorably with competitor Bild.de's score of 32. Ströer cited a positive correlation coefficient of 0.85 between media brand trust and advertising acceptance, arguing that higher trust translates directly into greater willingness among users to engage with advertising.

Statista: positioning as AI's data layer

The DaaS & E-Commerce segment reported a mixed year. Revenue fell 1.6% to €352.0 million, with the Data as a Service sub-segment (primarily Statista) posting marginal growth of 0.6% to €165.1 million and the E-Commerce sub-segment (AsamBeauty) declining 3.5% to €186.9 million. Adjusted EBITDA for the segment dropped 14.1% to €41.6 million.

Statista's strategic repositioning toward AI applications was a key theme. The data platform now offers access through multiple channels: its website, REST API integration, a dedicated MCP server for AI agents, built-in integrations with partners including Perplexity, Canva, and Microsoft Copilot, and raw data extraction tools. The Model Context Protocol, originally developed by Anthropic, has become a standard interface for connecting AI models to external data sources and has been adopted across the advertising technology industry throughout 2025 and 2026.

Approximately 85% of Statista's data is proprietary or exclusive third-party content, drawn from more than 3 million consumer interviews and over 20,000 sources. Co-CEO Christian Schmalzl noted during the earnings call that some clients, like Shopify, had already seen consumption increase 25-fold after integrating Statista data through AI workflows, though results varied significantly across the customer base.

Statista disposed of a small strategy and consulting unit by year-end 2025 that had generated €8 million in revenue with no material earnings contribution. For 2026, Statista expects continued revenue growth and a double-digit million improvement in free cash flow.

The 2026 outlook

Ströer guided for organic revenue growth in the low to mid-single-digit percentage range for fiscal 2026. For adjusted EBITDA, the company expects largely stable results year-over-year, though cash EBITDA (before IFRS 16 effects) should develop in line with sales. Free cash flow before M&A is expected to improve.

For Q1 2026, the company anticipates OOH Media sales slightly above prior-year levels, even against a strong prior-year comparison that included 15.3% growth driven partly by Germany's federal elections. Digital & Dialog Media should see sales growth broadly in line with Q4 2025's 9% pace. DaaS & E-Commerce is expected to decline by approximately €9 million due to the Statista consulting unit disposal.

Several important caveats accompany the outlook. Müller acknowledged that geopolitical uncertainty, including the Middle East conflict, could affect advertising sentiment. He described the current advertising market as characterized by low consumer and corporate confidence, with TV and print under sustained pressure. But he also expressed optimism about structural trends favoring OOH, noting a duopolistic market structure in Germany where declining competition has allowed Ströer to negotiate more favorable rent terms on concession contracts.

Müller put a longer-term number on the AI cost opportunity: up to €50 million in savings over five years, though he cautioned that meaningful impact would not materialize in the next two years. He was explicit about the operational mechanics behind that figure. Every order today passes through four, five, or six pairs of hands, according to Müller. In the future, that chain would be reduced to one or two touchpoints at most. The national sales force of 750 people illustrates the imbalance: only around 100 of them work directly with clients, while the rest operate in back-office functions that the Ad Manager is designed to automate. But Müller was equally explicit that this is not a cost-cutting exercise. "This is really a side effect," he told analysts. The primary objective is transformation - and he predicted the broader OOH industry would begin following within four quarters, with a full shift completed in two to three years.

On the revenue side, he pointed to Ströer's local customer base of approximately 30,000 to 50,000 SMEs, with an average ticket of roughly €7,500, and argued that the Ad Manager could expand this to 100,000 customers. If 40% of those used self-service booking, both revenue and profitability would increase substantially.

The company also announced its first-ever group chief technology officer, Sven Scheffler, who took up the role on March 1, 2026. A webinar scheduled for April 2026 will provide additional detail on the transformation strategy. The annual financial report is due on March 23, 2026, with Q1 2026 results scheduled for May 12.

Why this matters for the marketing community

Ströer's pivot raises questions that extend well beyond a single company's earnings report. The out-of-home advertising sector has spent the past decade digitizing its physical infrastructure - converting static billboards to digital screens, building programmatic buying capabilities, and integrating with demand-side platforms. That work created the inventory. But the sales process remained stubbornly analog, particularly in local markets, where small-ticket transactions are expensive to process and campaigns are complex to plan.

The Ströer Ad Manager concept - automated, AI-generated campaign proposals bookable in a single click - mirrors developments in digital advertising where Amazon launched its own AI agent for automated campaign management in November 2025 and Google's Ads platform has shifted from manual optimization to AI-powered automation over 25 years. What is different here is the application of those principles to a physical media business with entirely distinct operational complexity.

Public Mind's ambition to create standardized impact metrics for OOH addresses a gap that the industry's own trade bodies have identified. Germany's BVDW published a programmatic curation whitepaper in February 2026 that explicitly positioned curation and measurement standards as foundational to programmatic ecosystem growth. Ströer SSP GmbH was among the 13 contributing organizations.

The €2 million price tag for each of the two platforms underscores a broader shift in the economics of AI adoption. When Ströer built its SSP, the company invested tens of millions over time. Now, management argues, the same class of transformational capability can be deployed for a fraction of that cost by building on top of commercially available LLM technology. Whether that cost estimate proves accurate at scale - and whether AI agents can reliably handle the complexity of thousands of simultaneous local advertising campaigns - remains to be seen.

Ströer became the newest member of IAB Europe in February 2025, bringing its expertise in OOH, DOOH, and online media to the European-level association for digital marketing. That membership now takes on added significance as the company positions itself at the intersection of physical infrastructure and AI-powered automation.

Summary

Who: Ströer SE & Co. KGaA, a Cologne-based MDAX-listed media company with approximately 13,743 employees at around 100 locations, led by co-CEO and founder Udo Müller, co-CEO Christian Schmalzl, and CFO Henning Gieseke. Analysts from Bernstein, Goldman Sachs, Barclays, JPMorgan, Deutsche Bank, Berenberg, and Kepler Cheuvreux participated in the earnings call.

What: Ströer reported record preliminary revenue of €2,075.1 million for fiscal year 2025, with adjusted EBITDA of €625.9 million, while announcing a strategic transformation from an advertising space marketer to an AI-driven platform business. The plan centers on two AI tools: the Ströer Ad Manager, a transaction and automation engine for local and national sales, and Public Mind, a predictive intelligence layer for measuring OOH campaign impact. Each platform is estimated to cost approximately €2 million to develop.

When: Preliminary and unaudited figures were published on March 5, 2026, alongside the earnings call. The Ströer Ad Manager MVP phase begins Q2 2026 with a targeted go-live by Q4 2027. Public Mind's proof of concept runs Q2-Q4 2026, with full enterprise rollout planned for 2028 onward. The annual financial report is due March 23, 2026.

Where: Ströer operates primarily in Germany, with additional activities in Poland and international data services through Statista. The company's OOH infrastructure spans the German market, where OOH advertising reached a record 10.0% market share. Statista operates globally with integrations across AI platforms including Microsoft Copilot, Perplexity, and Canva.

Why: Ströer's transformation responds to two converging forces. The German advertising market in 2025 presented challenging conditions, with TV and print declining and corporate confidence subdued. Simultaneously, advances in AI - particularly large language models and agentic AI frameworks - have made it technically and economically feasible to automate complex sales processes that previously required extensive manual coordination. The company sees an opportunity to multiply its local customer base from 30,000-50,000 to 100,000 SMEs, introduce self-service booking to a business that has never had it, and establish OOH impact measurement standards comparable to what digital performance platforms already provide.
