What Siltronics does
Siltronic AG is a Munich-headquartered, publicly listed manufacturer (Frankfurt Stock Exchange, ticker WAF; MDAX and TecDAX constituent) of hyperpure silicon wafers for the global semiconductor industry. Its product portfolio spans polished wafers, epitaxial wafers and specialty wafers with diameters up to 300 mm, produced at manufacturing sites in Germany (Munich, Freiberg and Burghausen), Singapore (including the FabNext 300mm facility jointly developed with Samsung) and Portland, Oregon, employing approximately 4,300 people worldwide.
The company's underlying technology is built around proprietary crystal-pulling methods (Czochralski and Float Zone), epitaxial deposition and precision polishing processes developed over a heritage dating to 1953 (with the listed entity spun out of Wacker Chemie at the 2015 IPO). It is one of three global leaders in merchant silicon wafer supply, alongside Shin-Etsu and GlobalFoundries/UMC-aligned suppliers, and supplies tier-1 logic, memory and foundry customers including Intel, Samsung, TSMC, SK Hynix, GlobalFoundries, UMC and Texas Instruments under long-term agreements.
Siltronic generates revenue almost entirely through direct enterprise hardware sales of wafers under multi-year contracts; pricing is negotiated per specification and volume rather than published. R&D services are conducted through joint development with partners such as imec (GaN-on-Si and the EU Chips Act SPINS quantum pilot line), IKZ/PVA TePla (aluminum nitride crystals) and cosine (NewAthena space telescope substrates). A EUR 273 million capital increase was completed in June 2026 to fund capacity and balance-sheet flexibility, with management guiding to more than EUR 2.2 billion revenue and EBITDA margins in the high 30s by 2028.
