What Mubea does

Mubea (legal name: Muhr und Bender KG) is a privately held, family-owned German automotive Tier 1/2 supplier headquartered in Attendorn, Germany, founded in 1916/1917. The company specializes in the development and manufacture of high-strength spring components and related lightweight products for the global automotive industry, organized across five core product domains: Chassis (coil springs, stabilizer systems, suspension components, GFRP composites, and performance wheels), Body (Tailor Rolled Blanks, CFRP structural and visual parts, interior components, and forming tools), Powertrain (valve springs, belt tensioners, connecting products, transmission springs, tubular shafts, and fine-blanked parts), Industry (disc springs, compression springs, hydrogen technology components, and cooling/evaporator plates), and Aviation (Mubea Aviation with Nadcap-accredited manufacturing). Its underlying technology stack includes proprietary processes such as TRB (variable wall thickness blanks), MCF (cast forging), Fiberject (thermoplastic carbon injection molding), MLR/MACS/MARD chassis systems, and precision fine blanking up to 10,000 kN, supported by vertically integrated in-house tool-making and cold rolling.

Mubea generates revenue primarily through long-term OEM supply contracts with global automotive manufacturers, where components are co-developed from early vehicle program stages and priced via quote-based negotiations. Secondary revenue streams include the Mubea Aftermarket Services webshop for independent spare parts distribution, direct industrial sales for non-automotive applications, and aerospace component supply through Mubea Aviation. The company operates 70 manufacturing and operational facilities across 22 countries, employs approximately 17,200 people globally, and reports annual revenue of approximately €3.6 billion, with at least one Mubea product installed in more than 50 million new vehicles per year.

The business model is OEM-embedded and sales-led, with technical co-development partnerships preceding series production awards. Mubea is positioning itself for the vehicle electrification transition through BEV-targeted lightweight components (MLR coil springs, GFRP blade springs, TRB battery cases, performance wheels), while simultaneously expanding adjacent verticals including hydrogen electrolysis components (H2T), urban e-mobility (U-Mobility e-cargo bikes), and aerospace. Family ownership under the Muhr family (with Thomas Muhr as CEO) provides long-term strategic stability with no disclosed external institutional investors.
