ASTA

What ASTA does

ASTA Energy Solutions AG is an Austrian manufacturer of precision-insulated copper winding materials serving the global electrical energy ecosystem, headquartered in Wiener Neustadt, Austria. Founded in 1814, the company operates six production sites across five countries (Austria, Bosnia and Herzegovina, Brazil, China, and India) and employed 1,489 people as of 2025. Its product portfolio addresses three primary end markets: power generation (including wind, hydro, and other generation technologies), power transmission (including HVDC, transformers, and switchgear), and e-mobility (traction motors and electric vehicle components). The company is led by CEO Heinz Riedler.

The company's core technology centers on precision insulation of copper conductors down to the micrometer level, including continuously transposed conductors (CTCs), which are specialized copper conductor configurations used in high-performance transformers and rotating electrical machines. ASTA operates certified quality systems including EN 9100 (aerospace), IATF 16949 (automotive), and IRIS (rail), enabling qualification as a tier-1 supplier to major energy and mobility OEMs including Siemens Energy, GE Vernova, Hitachi Energy, Andritz, and Siemens Mobility. Its business model is B2B contract manufacturing of engineered components, monetized through volume pricing on long-cycle infrastructure projects; components have been supplied to high-profile installations including the Dogger Bank offshore wind farm.

In 2022, ASTA launched the "ASTA recycles" pilot process for upcycling insulation materials, aligning with circular-economy mandates increasingly required by European energy OEMs. The company completed an IPO in January 2026 and was admitted to the SDAX index on June 22, 2026, marking its transition to public capital markets. Disclosed 2025 net sales were EUR 695 million.
