X-FAB Semiconductor Foundries

What X-FAB Semiconductor Foundries does

X-FAB Semiconductor Foundries (X-FAB Silicon Foundries SE) is a pure-play specialty foundry group founded in 1992 in Erfurt, Germany and headquartered in Tessenderlo-Ham, Belgium, listed on Euronext Paris under ticker XFAB since April 2017. The company operates six wafer fabs across Malaysia (Kuching/Sarawak), Germany (Erfurt, Itzehoe), France (Corbeil-Essonnes), and the United States (Lubbock), employing approximately 4,300 people, and provides analog/mixed-signal semiconductor manufacturing services to fabless semiconductor firms and integrated device manufacturers. Its primary end markets are automotive, industrial, and medical, with a secondary presence in communication and consumer applications; automotive, industrial, and medical are explicitly designated as primary customer segments.

X-FAB's technology portfolio spans 13 process families with more than 450 options at geometries from 1.0 µm to 110 nm, covering modular CMOS and SOI processes, MEMS with or without integrated CMOS, silicon carbide (SiC) processing on 6-inch wafers, gallium nitride (GaN-on-Si) on 8-inch wafers, heterogeneous integration and 3D wafer-level packaging, high-voltage CMOS (including the XP018 180 nm platform rated from -40 °C to 175 °C), embedded non-volatile memory including automotive-grade options, silicon photonics, and silicon-based microfluidics. The company supports its customer base through design tooling (FeatureXplorer, ResourceXplorer), an IP Portal with 760+ entries from partners such as Alphacore, Fraunhofer IIS/EAS, Moortec, and Secure-IC, and the X-CHAIN network of 62 qualified design and supply-chain partners spanning EMEA, North America, Asia Pacific, and South America. In February 2026, Damien Macq succeeded Rudi De Winter as CEO, having previously served as COO since April 2023.

The business model is pure-play foundry wafer fabrication services sold via quote-based, multi-year contracts to fabless and IDM customers, with revenue generated per wafer processed and no public pricing list. FY2025 revenue was USD 870.3 million (+7% YoY), with Q4 2025 revenue of USD 222.3 million (+18% YoY) and Q3 2025 revenue of USD 228.6 million (+11% YoY, +6% QoQ). Q1 2026 guidance is USD 190-200 million. Strategic actions in 2025-2026 include a €127.4M German federal and Thuringian grant (approved under the European Chips Act in December 2025) for the Fab4Micro Erfurt microsystems expansion targeting initial production by end of 2028, expanded collaboration with Cadence on automated design migration, and cost-efficiency measures including planned high single-digit percent headcount reductions following a USD 9.3M SiC wafer agreement renegotiation charge that compressed Q4 2025 EBITDA margin.
