Emerald Horizon has begun trading on the Vienna Stock Exchange, listing in the Standard-Market segment with a reference price of €760 per share.
The Graz-based company, which develops compact thorium reactors, marks a significant entry for advanced nuclear technology on the Austrian market.
Founder Florian Wagner indicated that commercial readiness for the Thorium reactors is targeted within three years.
Despite strong interest from potential partners, Wagner acknowledged that the political environment remains challenging for the sector.
The listing provides the company with a public capital-raising platform as it moves toward its commercialization timeline.
The debut comes as European markets see renewed activity in specialized industrial and energy-tech listings.
