Dürr Group sells environmental technology to Stellex Capital
Bietigheim-Bissingen — Dürr AG has entered into an agreement with a subsidiary of Stellex Capital Management LLC (Stellex) on the sale of its environmental technology business with an enterprise value of € 385 million. This comprises the areas of exhaust air purification technology and sound insulation systems and forms the Clean Technology Systems Environmental division within the Dürr Group. With this sale, the mechanical and plant engineering company is completing the simplification of the Group structure announced a year ago and underlining its strategic focus on the automation of production processes. At the same time, the Group is acquiring a stake of around 25% in Environmental Technology.
The enterprise value of the environmental technology business is around € 385 million. After deducting the costs for the acquisition of the reverse takeover and other transaction-related costs, the Dürr Group expects net proceeds of around € 250 million. This is to be used to strengthen the Group by reducing debt. The closing of the transaction is subject to the usual approval requirements and is expected to take place in the fourth quarter of 2025.
Dürr had announced in mid-2024 that it was examining strategic options for the environmental technology business, including a possible sale. The sale that has now been agreed will enable the Group to achieve its goal of a leaner structure with just three divisions instead of five. At the same time, the company is now focusing consistently on its core business with automated and sustainable production technologies. Dürr had already sold the Danish filling technology company Agramkow in the previous year as part of the simplification of the Group structure. In addition, the business with the automotive industry was bundled in the new Automotive division at the beginning of 2025.
With its owner Stellex, the environmental technology business is well positioned to expand its leading position and has the resources to support the expected growth. In 2024, the environmental technology business generated sales of € 407 million and employed around 1,300 people, including around 450 in Germany. The headquarters are located in Bietigheim-Bissingen, and the business is operated at 16 locations in 12 countries worldwide.
Dürr’s environmental technology systems are used in various end markets and sectors, for example in the chemical industry, automotive production and odor removal.
Concentration on the core business
Dr. Jochen Weyrauch, CEO of Dürr AG: “The environmental technology business has grown strongly in recent years and has established itself as a global market leader. However, it lies outside our strategic core business around automation technology. The new owner, Stellex, therefore offers better opportunities for further growth in environmental technology. The sale will make the Dürr Group leaner and sharpen its strategic focus. We will use the proceeds from the sale to strengthen our company.”
Karthik Achar, Partner at Stellex: “We are delighted to become the new owner of Dürr’s Clean Technology Systems Environmental division. We see the division as a leading global provider of environmental filtration and air pollution control solutions, which are key technologies for a wide range of industrial and adjacent markets. The long-standing customer relationships are proof of the company’s technical expertise.”
New forecast for net financial status and review of the
Administrative structures
Based on the expected net proceeds from the sale, Dürr AG is adjusting its forecast
for the net financial status as at December 31, 2025 to € ‑250 to ‑300 million.
The previous forecast was € ‑500 to ‑550 million. — The disposal of Environmental Technology and the sale of Agramkow, which will be completed in 2024, will reduce the Dürr Group by around 10% in terms of sales. Against this backdrop, the company is currently reviewing its administrative structures. The aim is to adapt the administrative area to the new size of the company and at the same time make it more efficient.
