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.
