History

2024 until today

On September 23, 2024, AT&S and the Italian company SO.MA.CI.S. S.p.A. signed an agreement for the sale of AT&S Korea CO., LTD. and thus the AT&S plant in Ansan, South Korea. The purchase price (equity value) amounted to approximately EUR 405 million.[12]

On September 30, 2024, Andreas Gerstenmayer, who had been CEO of AT&S since February 2010, resigned for personal reasons.[13]

On February 26, 2025, it was announced that Dr. Michael Mertin will be the new CEO of AT&S AG for the next three years from May 1, 2025.[14]

On June 3, AT&S officially opened its new Competence Center for R&D and IC Substrate Production in Leoben, Austria. With the opening of “Hinterberg 3” (HTB3), AT&S is the first and only company in Europe with local capabilities for developing and producing IC substrates, which are critical components that deliver power and data to semiconductors in high-performance microchips.[15]

In the course of the Supervisory Board meeting after the 31st Annual General Meeting of AT&S AG on July 3, 2025, Andy Mattes was elected as the new Chairman of the Supervisory Board of AT&S AG.[16]

On August 8, 2025, CFO Petra Preining announced that she will retire as CFO of AT&S AG on August 31, 2025. The Supervisory Board was tasked with finding a suitable successor.[17]
