Investment Screening Reform in Germany – A balance between freedom of investment and security interests
15 October 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. The new shares were placed at a price of €91, resulting in gross proceeds of €273 million.
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.
