Porsche is continuing its restructuring efforts by shutting down several subsidiaries, including battery specialist Cellforce Group, as the company narrows its focus to core operations.
Porsche said Cellforce no longer has a viable long-term business outlook under the company’s revised strategy and confirmed that discussions regarding closure of the business will begin with employee representatives.
The move affects the remaining 50 employees at Cellforce. Cellforce was originally established as a joint venture between Porsche and Customcells to develop high-performance battery cells for Porsche electric sports cars.

Porsche took full control of the company in 2023 and initially expanded its ambitions before significantly scaling back operations in 2025.
At the time, around 200 of the company’s 290 employees reportedly lost their jobs, while others were offered transfers to PowerCo in Salzgitter.
“As part of Porsche AG’s strategic realignment and its technology-open powertrain strategy, Cellforce GmbH no longer has a sufficiently viable long-term perspective,” Porsche said in a statement.

The latest restructuring follows Porsche’s recent decision to sell its stake in the Rimac Group and the Bugatti Rimac joint venture.
The buyer was a consortium led by investment firm HOF Capital with backing from the Sawiris family.
Michael Leiters, Porsche’s chief executive officer, said the company needed to prioritise its core business activities.
“Porsche must refocus on its core business. This is the indispensable foundation for a successful strategic realignment,” Leiters said.
“This forces us to make painful cuts — including our subsidiaries,” he added.

Porsche is also winding down Porsche eBike Performance GmbH, which develops electric bicycle drive systems.
The closure affects around 350 employees across sites in Ottobrunn, Germany, and Zagreb, Croatia.
Porsche attributed the decision to “fundamentally changed market conditions.” The unit had previously incorporated Greyp, an electric bicycle company founded by Mate Rimac.
In addition, Porsche confirmed plans to shut down software subsidiary Cetitec in Pforzheim. Cetitec developed specialised data communication software for Porsche and the broader Volkswagen Group.

The closure affects around 60 employees in Germany and another 30 employees in Croatia.
Porsche said changing market conditions and shifts in development responsibilities contributed to the decision.
