Overview

SW Umwelttechnik Stoiser & Wolschner AG is an Austrian industrial group that develops and produces precast concrete components for building and expanding infrastructure both above and below ground. The company was founded in Klagenfurt in 1910 as a family business and today describes itself as a family enterprise with a long industrial tradition. Its headquarters are at Bahnstraße 89 in Klagenfurt, and its core markets are Austria (since 1910), Hungary (since 1990) and Romania (since 2001). The product range spans two main business areas: civil engineering and transport infrastructure, and building construction and housing. Typical products include pipes for sewerage and drainage, large containers and elements for road construction, and walls, beams and columns for residential and structural building. The company positions these products as long-lasting, resource-efficient solutions that support the responsible use of natural resources. It works exclusively with concrete, which it highlights as the world's most widely used building material, and it emphasizes a low energy input in production, long product lifetimes, low maintenance requirements and the regional availability of raw materials such as gravel, sand, water and cement. Recycled concrete is used to return production waste into the material cycle. SW Umwelttechnik operates nine locations and employs 785 team members in total, according to figures published on its website. The same source reports revenue of EUR 112.5 million and EBITDA of EUR 13.8 million. Its operating subsidiaries include SW Umwelttechnik Österreich GmbH with sites in Klagenfurt, Lienz and Sierning; SW Umwelttechnik Magyarország Kft. with sites in Majosháza, Alsózsolca and Bodrogkisfalud; and SW Umwelttechnik România S.R.L. with sites in Izvoru and Orţişoara. This multi-country footprint allows the group to serve local demand while keeping transport distances short. The company has been listed on the Vienna Stock Exchange since 1997 and is traded in the 'standard market auction' segment under the ticker SWUT. It presents itself as an internationally active, listed company committed to transparency and a true and fair view for shareholders. The Wolschner Privatstiftung holds more than 40% of the issued share capital. Management sees long-term market potential in European Union support for infrastructure projects that promote responsible and sustainable environmental use, and it pursues a strategy based on product optimization and utilization of its established production capacities.

History

SW Umwelttechnik Stoiser & Wolschner AG traces its origins to 1910, when the family business was founded in Klagenfurt, Austria. From that base the company developed into a producer of precast concrete components for infrastructure, supplying products used both above and below ground. Its home market of Austria has been served continuously since 1910. The company expanded into Central and Eastern Europe after the political changes of 1989/1990. It began operations in Hungary in 1990, establishing a presence that today includes production sites in Majosháza, Alsózsolca and Bodrogkisfalud. In 2001 it extended its footprint to Romania, where it operates through SW Umwelttechnik România S.R.L. with sites in Izvoru and Orţişoara. This staged geographic expansion allowed the group to serve local demand and keep transport routes short, a factor it presents as both an economic and an environmental advantage. A major corporate milestone came in 1997 with an initial public offering on the Vienna Stock Exchange. The company has remained listed and today its shares trade in the 'standard market auction' segment under the ticker SWUT, with 725,999 shares. The Wolschner Privatstiftung holds more than 40% of the issued share capital, preserving a foundation-linked ownership anchor alongside the public float. Over the decades the product portfolio broadened into two principal business areas: civil engineering and transport, and building construction and housing. Products range from pipes for sewerage to large containers for road construction and to walls, beams and columns for residential and structural building. The company states that its modern production facilities, broad product range and specific knowledge of regional markets have made it a market leader in many areas. In the 2020s the group presents itself as an internationally active, listed company with nine locations and 785 team members, reporting revenue of EUR 112.5 million and EBITDA of EUR 13.8 million. It frames its mission around raising quality of life and the attractiveness of its markets, and it sees long-term potential in European Union support for infrastructure projects that promote responsible and sustainable use of the environment. Its strategy emphasizes product optimization and the utilization of established production capacities to achieve sustainable, profitable growth.
