In the Spotlight

About Dürr: Dürr Systems AG is part of the Dürr Group and operates globally in the automotive industry and other markets, specializing in painting technology, final assembly, dispensing technology, and consulting. As a market leader, Dürr designs and implements turnkey systems and manufactures high-quality machines and robotic technology. The company has proven expertise in digital and sustainable solutions. Its portfolio also includes production technologies for electrode coating and high-performance air pollution control systems for various industries. As of 2024, Dürr Systems AG employs more than 8,000 people. The Dürr Group is one of the world’s leading mechanical and plant engineering firms, with particular expertise in the technology fields of automation, digitalization, and energy efficiency. Its products, systems, and services enable highly efficient and sustainable manufacturing processes — primarily in the automotive industry and for producers of furniture and timber houses, but also in sectors such as the chemical and pharmaceutical industries, medical devices, electrical engineering, and battery production. In 2024, the company generated sales of €4.7 billion. The Dürr Group has around 18,400 employees and 139 business locations in 33 countries. As of January 1, 2025, the former Paint and Final Assembly Systems and Application Technology divisions were merged to form the new Automotive division. Since then, the Dürr Group has been operating in the market with four divisions: • Automotive: painting technology, final assembly, testing and filling technology • Industrial Automation: automated assembly and test systems for automotive components, medical devices, and consumer goods, as well as balancing technology solutions and coating systems for battery electrodes • Woodworking: machinery and equipment for the woodworking industry • Clean Technology Systems Environmental: air pollution control and noise abatement systems

Strategic Focus on Automation of Production Processes. Dürr AG has concluded an agreement with an affiliate of Stellex Capital Management LLC (“Stellex”) on the sale of its environmental technology business. This comprises the areas of exhaust air purification technology and sound insulation systems and forms the Clean Technology Systems division within the Dürr Group. With this sale, the mechanical and plant engineering firm is completing the simplification of the Group structure announced a year ago, underlining its strategic focus on the automation of production processes. At the same time, the Group retains a re-investment in environmental technology amounting to approximately 25%. The enterprise value of the environmental technology business is approximately €385 million. After deducting the costs for acquiring the re-investment and other transaction-related costs, the Dürr Group expects net proceeds from the sale of around €250 million, which will be used to strengthen the Group by reducing debt. The transaction is subject to standard approvals and is expected to close in the fourth quarter of 2025.

In mid-2024, Dürr announced the assessment of 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 consistently focusing on its core business in 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, business with the automotive industry was consolidated into the new Automotive division at the beginning of 2025.

Under Stellex’s ownership, the environmental technology business is well positioned to expand its leadership, benefitting from additional resources to support expected growth. In 2024, the business generated sales of €407 million and employed around 1,300 people, including approximately 450 in Germany. The head office is located in Bietigheim-Bissingen, and operations span 16 locations across 12 countries worldwide. Environmental technology systems from Dürr are used in a variety of end-markets, including chemicals, odor control, and automotive.

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 the global market leader. However, it lies outside our strategic core business relating to automation technology. The new owner, Stellex, therefore offers better opportunities for further growth in environmental technology. Through this sale, the Dürr Group will become leaner and sharpen its strategic focus. We will use the proceeds from the sale to strengthen our company.”

Karthik Achar, Partner at Stellex:
“We look forward to becoming the next steward of Dürr’s Clean Technology Systems Environmental division and we welcome the company into our investment portfolio. We view the division as a global leader in environmental filtration and pollution control solutions — critical technologies that serve a wide range of industrial and adjacent markets. Its long-standing customer relationships are a testament to the company’s engineering excellence. We are eager to partner with the management team and its employees to shape the next phase of its growth.”

Dr. Sebastian Baumann, Head of the Clean Technology Systems Environmental division:
“We can look back on a successful development in the environmental technology business and are convinced that we can realize our potential even better as an independent company. With Stellex at our side, new opportunities for growth and innovation are opening up — both in our established business areas and in pioneering technology fields such as carbon capture and heat storage.”
