Subra Raises €40 Million Series A And Acquires Its Partner THEVA

The funding will support Subra’s acquisition of THEVA Dünnschichttechnik, a Germany-based manufacturer of superconducting materials.

By combining Subra’s advanced superconducting cable technology with THEVA’s expertise in material science and manufacturing, the merged company aims to become a European leader in high-performance superconductors for energy systems, infrastructure, and industrial applications.

The move also strengthens Europe’s supply chain resilience and technological independence in a strategic sector.

Headquartered in Denmark, the combined entity will operate across both Danish and German facilities to scale production and serve global markets.
