Wilo had a good year in 2025. Net sales hit €1,918.7 million — a 4.5% currency-adjusted increase — and EBITDA jumped 39% to €212 million, pushing the margin to 11.1%. Consolidated net income climbed nearly 240% to €65 million. Free cash flow more than doubled, rising over 80% to €66.4 million.
CEO Oliver Hermes summed it up plainly: the numbers show that their regional structure and long-term strategy are working. Wilo has been pushing a “region-for-region” model for some time now — building closer to where customers actually are — and 2025 was the year it showed up clearly in the financials.
But the bigger news isn’t the earnings. It’s where Wilo is heading next.
The company has merged its sustainability strategy with a new AI-focused direction under the name “Pioneering WATER AI for You.” The idea is that AI and sustainability aren’t separate tracks — they’re the same track. Hermes put it bluntly: AI is probably the most powerful lever they have for reducing environmental impact, and treating it as an add-on to sustainability work no longer makes sense.
The three-pillar WATER-AI strategy is fairly concrete: integrate AI into Wilo’s own products, support the broader AI infrastructure chain (think data centres, cooling systems, water management for tech facilities), and use AI internally in day-to-day operations.
On the sustainability side, 2025 wasn’t quiet either. Wilo earned its fourth consecutive EcoVadis Platinum Medal, won the German Sustainability Award for the second time, and made the CDP’s A List. In early 2026, they opened the Health Cube — a 5,500 m² health and wellness centre at their Dortmund headquarters — and laid the groundwork for a Global WATER AI Academy, which launches this year.
None of this reads like a company playing it safe. The financial results give them room to move, and they seem intent on using it.
