What Knorr-Bremse makes

Knorr-Bremse is the global market leader for braking systems on commercial vehicles and rail vehicles. The company's Truck division produces air disc brakes, drum brakes, and complete wheel-end assemblies for heavy trucks, buses, and trailers. Alongside mechanical stopping hardware, the division supplies the electronics that activate and modulate those systems: electronic braking systems (EBS), advanced emergency braking systems (AEBS), adaptive cruise control, and lane departure warning. Air management is a parallel product family covering compressors, air dryers, and trailer control modules that feed the pneumatic circuits running through every air-braked truck.

The SYNACT disc brake family, produced at the Aldersbach facility in Lower Bavaria, is the division's flagship commercial vehicle product. A retarder product line offers complementary hydrodynamic and electromagnetic braking for long-haul vehicles on mountain grades. The TRAVIS acquisition, completed in 2025 and 2026, added a commercial vehicle online booking and fleet services platform that extends the division's presence into fleet operations software.

Knorr-Bremse's Rail division serves train operators and rolling stock builders with an overlapping set of disciplines: train braking systems, entrance and door systems, HVAC, platform screen doors, and power electronics. Rail is now the larger of the two divisions by revenue, at €4.3 billion in 2025 versus €3.5 billion for commercial vehicles, and is growing. This profile focuses on the Tier-1 supplier commercial vehicle segment, which is the basis for the Berylls Top-100 ranking.

The company holds patents across brake actuation, pneumatic control architecture, and vehicle stability systems. Its products appear as original equipment on the majority of heavy trucks produced in Europe and at significant share in North America and Asia.

Financial performance

Knorr-Bremse's Truck division reported revenue of €3,503 million in fiscal year 2025, down 8.8% from €3,842 million in 2024. The EBIT margin held at 9.1%, the same as the prior year, producing segment EBIT of €319 million. The revenue decline reflects a broad contraction in European and North American truck production rather than share loss; European truck registrations fell to multi-year lows across 2024 and into 2025 as fleet customers absorbed post-pandemic replacement cycles.

At the group level, Knorr-Bremse reported revenue of €7,817 million in 2025, and free cash flow reached an all-time high of €790 million, with a cash conversion rate above 100% for the second consecutive year. The operating EBIT margin expanded to 13.0% for the group, up from 12.3% in 2024. The company had 30,913 employees as of December 31, 2025.

The Truck division has been subject to the BOOST restructuring program, including workforce adjustments: headcount fell from 13,550 at end-2024 to 11,981 at end-2025, a reduction of approximately 1,600 positions. The company has characterized this as disciplined cost management in response to market volume rather than structural retreat.

Revenue across the segment spans a bill of materials that includes both hardware components and the embedded electronics now standard in commercial vehicle safety regulation. The European General Safety Regulation mandating AEBS and LDW on new trucks has accelerated the electronic content per vehicle, partially offsetting the volume decline in unit terms.

For H1 2026, Knorr-Bremse reported group revenues of €4,080 million, up 3.1% year on year, with the Truck division delivering an operating EBIT margin of 11.7% — up from 9.9% in H1 2025. The group order book reached a record €7,887 million as of June 30, 2026.

Ownership and history

Georg Knorr founded the business in Berlin in 1905 to supply compressed-air brakes to the Prussian railway network. The company moved into commercial vehicle braking during the 1920s as pneumatic brakes became standard on trucks and buses. Growth through the twentieth century was organic and geographic, with manufacturing plants established in Germany, then across Europe, and eventually in North America and Asia.

Knorr-Bremse AG has been listed on the Frankfurt Stock Exchange under the ticker KBX since 2018, when the Thiele family executed a partial IPO. The Thiele family estate retains a significant share. The ISIN is DE000KBX1006. Headquarters remain at Moosacher Strasse 80, Munich, Germany. The company operates at over 100 locations in roughly 30 countries. Key commercial vehicle manufacturing sites include Aldersbach in Bavaria, plants in Hungary and the Czech Republic for European production, and facilities in China (Nanjing), India (Pune), and Mexico (Acuna) for regional OEM supply.

Certifications and quality

Knorr-Bremse states compliance with IATF 16949, the automotive quality management standard, across its commercial vehicle manufacturing operations. The company also states ISO 14001 environmental management system compliance. Per the company's quality disclosures, its facilities operate under multi-site IATF 16949 certification frameworks consistent with Tier-1 OEM supply requirements. Specific certificate issue dates are not published centrally; the company's quality team holds the documentation.

Braking systems supplied to OEM customers go through production part approval processes with each truck manufacturer, given the safety-critical classification of the parts.

Known customers

Relationships with these OEMs are long-dated, typically spanning multiple vehicle generations, because brake system qualification is a multi-year process tied to chassis architecture. Switching costs for an OEM requalifying a competing brake system are substantial, which gives established Tier-1 brake suppliers structural pricing stability.
