# 50 leading publicly traded companies in Austria

Tamtam tracks 58 publicly traded companies headquartered in Austria. This list ranks the 50 largest by number of employees on LinkedIn, led by STRABAG, Vienna Insurance Group (VIG) and ANDRITZ. Their median headcount is 1,619. Half of them were founded in 1950 or later. The most common headquarters are Vienna (25), Graz (3) and Innsbruck (2).

The largest publicly traded companies in Austria include a mix of established industrial groups and service providers. Among them are STRABAG, a construction technology group, Vienna Insurance Group, a major insurer in Central and Eastern Europe, and ANDRITZ, a global supplier of industrial plants and equipment. RHI Magnesita is a leader in refractory products, while Mondi Group specializes in packaging solutions. A1 Telekom Austria Group is a key telecommunications provider.

A notable pattern is the strong presence of companies with headquarters in Vienna, such as OMV, a sustainable fuels and chemicals company, UNIQA Insurance Group, Erste Group, and Raiffeisen Bank International AG. This suggests a concentration of corporate activity in the capital, spanning sectors from utilities and banking to specialized manufacturing and hospitality, as seen with DO & CO AG.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 11, 2026.
