What Autoneum does

Autoneum Holding Ltd. is a Swiss public company headquartered in Winterthur, listed on the SIX Swiss Exchange (AUTN) since its 2011 spin-off from Rieter. It is the self-described global market leader in acoustic and thermal management solutions for vehicles, supplying interior components (carpets, dash absorbers, floor insulators, trunk trims), exterior components (wheel arch liners, heat shields, underbody systems), and a battery housing portfolio (E-Fiber Flame Shield, Impact Protection Plate, Under-Battery Shield, next-generation Battery Lid) for light vehicles and commercial vehicles. Core technologies include glass-fiber-reinforced composites via Spray Transfer Molding (STM), long-fiber thermoplastic (LFT) systems, and Ultra-Silent textile-based acoustic and thermal insulation with up to 70% recycled polyester content; sub-brands Autoneum Pure. and Autoneum Blue. target sustainability and EV applications respectively.

The company operates approximately 70 production facilities across 25 countries with around 16,400 employees, organized into Business Groups covering Europe, North America, Asia, and SAMEA (South America, Middle East, Africa). Autoneum generates revenue through Tier 1 B2B hardware sales of custom-developed components directly to automotive OEMs under negotiated multi-year contracts; FY2025 revenue was CHF 2.29 billion, down 2.1% due to FX translation despite organic growth. Named customers include FAW-VW, FAW-Audi, FAW-Toyota, and Geely (acquired via Yiqi-Sihuan), alongside European OEMs. Recent strategic actions include the Borgers Automotive acquisition (April 2023, EUR 117M enterprise value) and the Chengdu Yiqi-Sihuan acquisition (December 2025), both expanding textile acoustics and Asian footprint toward a stated target of 20% Group revenue from Asia. The company received a CDP Leadership A rating in 2025 and announced closure of its London, Ontario facility in 2026 in response to U.S. tariffs on Canadian-assembled vehicles.

Core offering

Autoneum designs, develops, and manufactures acoustic and thermal management components for light vehicles and commercial vehicles, including interior products (carpets, dash absorbers, floor insulators, trunk trims), exterior products (wheel arch liners, heat shields, underbody systems), and a dedicated battery housing suite for electric vehicles (E-Fiber Flame Shield, Impact Protection Plate, Under-Battery Shield, and a next-generation Battery Lid). The company supplies these custom-engineered components directly to automotive OEMs worldwide from more than 70 production facilities across 25 countries.

Product overview

Autoneum is the global market leader in acoustic and thermal management solutions for vehicles, operating as a single-company manufacturer of lightweight components. The product portfolio centers on two core technology areas: acoustic materials for noise reduction and thermal management solutions for heat protection. The portfolio includes interior components (carpets, dash absorbers, floor insulators) and exterior components (wheel arch liners, heat shields, underbody systems) for light vehicles and commercial vehicles. For electric vehicles, Autoneum offers a comprehensive battery housing solutions suite including the E-Fiber Flame Shield, Impact Protection Plate, Under-Battery Shield, and the next-generation Battery Lid. Two sub-brands extend the portfolio: Autoneum Pure. (sustainable products with recycled content) and Autoneum Blue. (solutions optimized for electric vehicles). The company also provides tooling services, measurement systems, and simulation capabilities as part of its comprehensive offering. Supplier-facing operations are supported through integrated digital tools including the Compliance Process Manager (CPM), Supplier Development System (SDS) portal, and Electronic Data Interchange (EDI) systems.

Products and services

• E-Fiber Flame Shield Glass-fiber-based composite flame shield installed inside battery housing as a thermal barrier between battery cells and the vehicle interior. Withstands temperatures up to 1,400°C, resists hot particle impact and gas pressure during thermal runaway events, and is lighter and less brittle than conventional mica-based alternatives. Designed for electric vehicle battery packs.
• Impact Protection Plate (IPP) Long-fiber thermoplastic (LFT) based protection plate for battery packs that combines high mechanical stiffness with thermal insulation properties to protect against collisions, impacts, stones, debris, fire and corrosion from the underbody side, contributing to improved energy efficiency and driving range.
• Under-Battery Shield Ultra-Silent textile-based shield providing thermal insulation, heat leakage minimization, stone chipping protection, and rolling noise reduction for battery housings. Made entirely from polyester with up to 70% recycled content and fully recyclable at end of life.
• Battery Lid for BEVs Multifunctional top cover for battery-electric vehicle battery packs using Spray Transfer Molding (STM) technology with glass fiber reinforcement and polyurethane matrix. Consolidates multiple protective functions (flame retardancy, electromagnetic shielding, thermal and electrical insulation, thermal runaway confinement) into a single lightweight composite part, reducing assembly complexity and delivering 30% weight savings versus traditional manufacturing.
• Interior Components (Light Vehicles) Interior acoustic and thermal management products for passenger vehicles including carpets, dash absorbers, floor insulators, and trunk trims, designed to reduce cabin noise and manage thermal loads.
• Exterior Components (Light Vehicles) Exterior acoustic and thermal management products for passenger vehicles including wheel arch liners, heat shields, and underbody systems that reduce exterior noise, protect against heat, and contribute to lightweighting.
• Battery Housing Solutions Comprehensive battery housing components suite for electric vehicles, including E-Fiber Flame Shields, Impact Protection Plates, Under-Battery Shields, and battery lids designed for BEV applications.
• Exterior Components (Commercial Vehicles) Exterior acoustic and thermal management products for commercial vehicles (trucks and buses), including wheel arch liners, heat shields, and underbody systems engineered for heavy-duty duty cycles.
• Autoneum Pure. Sustainable sub-brand product line featuring acoustic and thermal management components made from recycled materials, supporting circular economy initiatives in vehicle applications.
• Autoneum Blue. Product line focused on acoustic and thermal management solutions optimized for electric vehicles and new mobility applications.
• Tooling Tooling services and solutions supporting the production of Autoneum's acoustic and thermal management components for automotive applications.
