What Webasto makes

Webasto is structured around three product lines: roof systems, battery systems, and thermal management solutions. Roof systems are the largest by far, generating approximately €3.0 billion in revenue in 2025, or 79 percent of the group total. The product range spans openable sunroofs and panoramic systems (both mechanical and glass), fixed glass roofs, and convertible soft- and hard-top systems for passenger cars. Webasto supplies these to original equipment manufacturers across Europe, North America, China, and the Asia Pacific region, and the company claims to equip roughly every other car with a sunroof or panoramic roof globally.

Battery Systems contributed approximately €300 million in 2025 and centers on traction battery packs for electric vehicles. Webasto designs, tests, and manufactures battery systems at its own facilities, including a high-volume plant in Dangjin, South Korea, that produces up to 1,000 battery packs per day. Thermal Management Solutions, at around €500 million, covers vehicle parking heaters, auxiliary heaters, HVAC systems, and thermal conditioning products for both conventional and electrified powertrains. Webasto introduced vehicle heaters in the 1930s and has continuously extended this category into EV-compatible systems, including high-voltage PTC heaters and battery thermal management hardware.

Research and development spending in 2025 was approximately €280 million, representing around 7 percent of group revenue. The company describes that level as consistent with recent years, indicating it has protected its development budget through the restructuring rather than cutting it as a cost lever.

Financial performance

Webasto reported group revenue of approximately €4.0 billion in fiscal year 2025, down 7.4 percent from €4.3 billion in 2024, which itself declined from €4.6 billion in 2023. The two-year revenue decline reflects a combination of weaker European and North American vehicle production volumes, intensified competitive pressure in China from domestic manufacturers, and mix effects from ongoing restructuring. EBIT, adjusted for restructuring charges and one-time items, was €51 million in 2025, compared with €63 million the prior year. On an unadjusted basis the annual result was negative, reflecting the cash cost of restructuring measures. The company secured financing through 2028 in 2025, removing near-term liquidity risk while transformation proceeds.

The regional revenue mix in 2025 was approximately 35 percent Europe, 28 percent Americas, 18 percent China, and 19 percent Asia Pacific. The APAC share increased four percentage points year over year, driven by growth in roof systems in India and battery program volumes. The company employed approximately 13,100 people at year-end 2025, reflecting workforce adjustments made as part of the ongoing restructuring.

Webasto is privately held, a Societas Europaea (SE), and prepares its financial statements under IFRS. It does not publish detailed EBITDA or net income figures separately from its annual accounts.

Ownership and history

Webasto was founded on March 7, 1901 by Wilhelm Baier as a small sheet-metal workshop in Esslingen, Germany. The company moved to Stockdorf near Munich in 1908, where it took its current name -- a contraction of "Wilhelm Baier" and "Stockdorf." After decades in bicycle accessories and vehicle accessories, Webasto developed its first foldable fabric vehicle roof in the 1930s and, shortly after, its first vehicle heater. Both product lines remain core to the group today.

The Baier family has retained ownership across all five generations of the business. Werner Baier, great-grandson of the founder, sits on the current Supervisory Board. The company is structured as a Societas Europaea, a European cross-border corporate form, and is not listed on any stock exchange. In March 2026, Webasto marked its 125th anniversary, citing the occasion as a moment of renewal alongside restructuring.

Webasto entered the North American market in February 1974. It entered China and established production there in later decades, with plants in multiple cities including Chongqing and several others serving local OEM customers. Battery systems activity began in 2015 with electromobility solutions, and the company opened its Dangjin battery plant in South Korea in 2022.

Certifications and quality

Webasto's production sites hold IATF 16949 certification, the sector-standard automotive quality management system, per the company's own certificates page, which lists plant-level certificates including active credentials for its Webasto Japan subsidiary with certification extended through December 2027. Individual plants also carry ISO 14001 environmental management certification; the Chongqing plant, for example, is cited in company materials as certified to ISO 9001, IATF 16949, and ISO 14001, and recognized as a Ford Q1 and FAW-VW Grade A supplier. Certification is maintained at the plant level across the group's more than 40 production sites, which is the standard Tier 1 structure for a multi-site global supplier. The company also publishes an annual Sustainability Report covering environmental and social performance targets.

Known customers

The roof systems segment at approximately €3.0 billion implies a broad OEM customer base across European, North American, and Asian manufacturers, consistent with Webasto's own positioning as a global systems partner. Specific program details beyond the above are not individually disclosed in available company materials.
