NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES OF AMERICA, AUSTRALIA, CANADA, JAPAN OR ANY OTHER JURISDICTION IN WHICH, OR TO PERSONS IN ANY JURISDICTION TO WHOM, SUCH RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE UNLAWFUL

Munich, June 15, 2026 – Siltronic AG, one of the world’s leading manufacturers of hyperpure silicon wafers, successfully completed a capital increase by way of an accelerated bookbuilding process under exclusion of subscription rights. The capital increase was executed as an international private placement with institutional investors and was significantly oversubscribed. Anchor shareholder HAL Trust has participated in the transaction with a meaningful order. The new shares were placed at a price of EUR 91, resulting in gross proceeds of EUR 273 million.

Supporting long-term growth in structurally attractive semiconductor markets

The capital raise will support Siltronic’s growth strategy, strengthen its balance sheet and serve general corporate purposes. Operating in a structurally growing semiconductor market, Siltronic benefits from long-term demand drivers such as artificial intelligence, digitalization and electromobility, which continue to support silicon wafer demand, particularly in 300 mm.

With its clear strategic focus on Leading Edge and Power wafers, the company is well positioned to capture attractive growth opportunities across key end markets. Supported by its position as a technology leader, strong R&D capabilities and long-standing customer relationships, Siltronic continues to advance its 300 mm product portfolio while maintaining its leading position in advanced 300 mm wafers. The ongoing ramp of the new 300 mm fab in Singapore is expected to further strengthen the company’s competitive position and support profitable growth over the medium term.

Strengthened financial profile and increased strategic flexibility

The successful completion of the capital increase materially strengthens Siltronic’s balance sheet and enhances its financial flexibility to capitalize on attractive market opportunities, including those driven by artificial intelligence, and support future profitable growth. 

Strong investor support underscores confidence in Siltronic’s strategy

“We are very pleased with the strong support from both existing and new institutional investors,” said Dr. Michael Heckmeier, CEO of Siltronic AG. “The successful placement underscores confidence in Siltronic’s strategic positioning and long-term growth prospects. With the additional capital, we further strengthen our financial foundation and enhance our ability to execute our strategic priorities while maintaining resilience across market cycles.”

Deutsche Bank, UBS and J.P. Morgan acted as Joint Global Coordinators and Joint Bookrunners.
