What Kovis Group does
Kovis Group is a privately held Slovenian industrial group (HQ in Brežice, foundry in Štore) that manufactures grey and nodular cast iron components for the railway, agricultural machinery, construction machinery, and adjacent industries. The group operates through four wholly owned subsidiaries — Kovis d.o.o. (parent and railway assembly), Kovis Livarna d.o.o. (foundry), Kovis BP, and Kovis Transporti (in-house logistics) — and serves about 200 active customers across 32+ markets, with named European rail operators (Deutsche Bahn, SlovakRail ŽSS, Czech Railways ČD) among certified buyers of safety-critical parts such as brake discs and axle boxes.
Core production is built around an integrated foundry-to-finished-component model: grey and nodular cast iron is melted, moulded on automated lines, and then CNC-machined, coated, and quality-tested in-house, including 3D sand printing for rapid prototyping, CFD and thermal/structural simulation in the design phase, mechanical sand reclamation, and laboratories for 3D measurement, digital radioscopy, NDT and dynamometer testing. Notable proprietary offerings include the K25 axle box bearing housing and the FUTURA Divided Rail Freight Brake Disc (developed under Horizon 2020), plus a SiNiMo cast iron grade tailored for trains exceeding 200 km/h that delivers roughly 9% weight reduction.
The revenue model is B2B direct industrial sales of custom cast and machined components, with quote-based pricing set per part specification and multi-year enterprise supply contracts typical for safety-critical railway parts. Revenue streams include hardware sales of castings and bracketed service revenue from co-development, prototyping, machining, coating, and logistics. The company cites a 20x sales-revenue increase and €100 million of investment over the past decade, sustained EU/state-aid-funded capacity projects (notably a 2018 €24.7 million modernization co-financed with €2 million of regional state aid), Platinum creditworthiness ratings (2019, 2020) and a 708 KW on-site solar plant commissioned in October 2023 covering about 3.8% of annual electricity consumption.

Kovis Group competitors and assessment
Company assessmentEmerging players
- Brembo S.p.A. Italian global leader in high-performance automotive braking systems that has been expanding into rail and commercial vehicle applications. Comparable as a friction/brake disc technology peer entering the railway segment where Kovis is already established.
Broad incumbents
- voestalpine AG: Austrian steel and technology group whose Railway Systems division produces rail components, turnout systems and track-related castings. Comparable in that voestalpine is a vertically integrated steel/rail supplier headquartered in the same Alpine-adjacent region, though vastly larger and more diversified than Kovis.
- Progress Rail (a Caterpillar company): Caterpillar's rail division supplying locomotives, freight wagon components, signalling and aftermarket services worldwide. Overlaps with Kovis in freight rail components and rebuild/refurbishment markets, but at significantly larger scale and broader scope.
- Wabtec Corporation: US-listed global provider of equipment, systems and services for freight and passenger rail, including brake components, bogies, and signalling. A much larger incumbent with overlapping product categories (brake discs, freight wagon components) but serving a far broader portfolio and global footprint than Kovis.
Direct peers
- SAF-Holland SE: European-headquartered supplier of trailer and railway components including axle systems and brake-related parts for freight wagons and locomotives. Comparable on the freight rail component side, though SAF-Holland is more diversified into commercial vehicle applications than Kovis.
- Knorr-Bremse AG: Global market leader in braking and other safety-critical systems for rail and commercial vehicles, supplying friction discs, brake calipers and bogie equipment. Directly comparable on the railway braking systems side, though at significantly larger scale and broader product scope than Kovis.
- Eisenwerk Würth GmbH: German specialty iron foundry producing complex cast iron and steel castings for railway, commercial vehicle and industrial applications. Comparable as a regional Central European iron foundry competing for similar railway casting programs.
- Miba AG: Austrian-headquartered specialist iron and steel foundry producing cast and sintered components for railway (bearings, brake discs, axle boxes) as well as automotive and industrial markets. Closest direct peer to Kovis in terms of product mix, niche specialization, and customer profile across Central European rail operators.
- GHH-BONATRANS Group: Germany- and Czech-based manufacturer of railway wheels, tyres, axles and wheel-set assemblies for freight and passenger rail. Comparable as a Central European railway component supplier, with overlap on freight wagon applications where Kovis supplies axle boxes and brake discs.
- DAKO-CZ: Czech manufacturer of brake systems, brake discs and friction materials for rail freight and passenger vehicles. Closely comparable to Kovis in size, geography (Central Europe), and product focus on railway braking components for freight wagons.
