What Kap does
KAP AG is a publicly listed German industrial holding company headquartered in Fulda, operating 18-19 production locations across 10 countries with approximately 1,550-1,600 employees. The company runs three specialized segments: flexible films (fabric-reinforced pool liners and 3D films via subsidiary CaPlast), engineered products (technical textiles and threads via MEHLER), and surface technologies (electrolytic metal coatings, anodizing, zinc/nickel coatings, and the Heiche Group subsidiaries). It serves B2B industrial customers primarily in automotive supply chains, pool/construction, and industrial textiles, with a stated positioning as market leader in surface solutions for metallic materials.
The company's revenue model is hardware sales of physical industrial components and coating services to enterprise customers through direct B2B sales. FY2025 revenue of €241.4 million (down 4.4% year-on-year) split across flexible films (€85.4M), engineered products (€99.2M), and surface technologies (€56.0M). Technology assets include proprietary coating processes such as the Conductance Washing Process for fuel cell iCAC components and the AdaProQ AI-supported data integration system for automotive coating lines, alongside specialty products like the BasaTexx FP fireproof basalt fabric. The company is controlled by The Carlyle Group (45.5% ownership) with FM-Verwaltungsgesellschaft mbH holding 25.7%, and trades on the Frankfurt Stock Exchange under ticker IUR.
KAP executes a portfolio strategy of acquiring and developing upper mid-size industrial businesses in high-margin niches while preserving subsidiary operational autonomy. Recent activity has been predominantly defensive: closing the Leisnig surface technologies plant (end 2025), the Hessisch Lichtenau engineered products site (by June 2027), the US Martinsville site (relocated to Bangalore, India), and the 2024 divestiture of the precision components segment. The company secured a €96 million syndicated loan refinancing in April 2026 at EURIBOR + 4.5%, reflecting a tight financing environment. Founder-style decentralized management has been overshadowed by Carlyle's controlling stake and a 2026 leadership transition in which sole Management Board member Ralph Rumberg (CEO, CRO) took over from Marten Julius.
