Scaling up to ≥1 GWh
Meltdown (2023-2025) 2023: Porsche takes full ownership of Cellforce Expansion Vision: Plans floated for up to 20 GWh capacity Business model deemed not economically viable due to slow EV market growth, insufficient volumes, and intense price pressure from Asian suppliers Battery-related special expenses rise April 2025: Porsche halts independent scale-up
Restructuring (2025) Aug 25, 2025: Porsche formally ends production expansion plans New Role: CFG becomes an independent R&D unit (cell + system development only) VW Integration: Expertise to support PowerCo via development contracts Financial Impact: €295M depreciation on production assets (FY 2025) Workforce: ~200 of 286–290 jobs cut (~70% reduction), effective Nov 30, 2025
