Indeed they are not. They are a Austrian GmbH, which is a special kind of company form that is not really comparable to a e.g. British or American Ltd.

Long story short, for being a publicly traded company, they would need to "transform" to an AG ("Aktiengesellschaft", where "Aktie" means "share of stock").

A GmbH is nothing “special”, its basically the most used corporate structure in Austria (and Germany).

Its a limited liability structure and most businesses from small to large that have private shareholders use it (Red Bull or Porsche Holding are GmbHs for example)

As I understood it, GmbH is like an LLC but with more paperwork.
