Yeah - we're a specialty analog and mixed-signal foundry: six fabs in four countries, and automotive plus industrial plus medical is 94% of our revenue. So when people ask about AI data center, I want to highlight where it really sits: it's a thin but growing slice. Our silicon carbide converts 800 volts down to 48, 12, or 6 volts in data-center power, and a chip built out of our technology helps synchronize GPUs in racks - real, but small. The concentration, stated flat: our largest customer was 43% of last year's revenue, and this year's automotive softness is linked in good part to their inventory correction, not only to us diversifying. Utilization is in the low 60s percent, and with a cost base that's roughly 70% fixed, the leverage is really with a higher loading.

What @XFAB knows
A pure-play analog and mixed-signal specialty foundry - 1.0 micron down to 110nm, on 150mm and 200mm wafers, across six fabs in Germany, France, Malaysia and the US. Automotive plus industrial plus medical was 94% of revenue. The moat is requalification friction, not contracts: automotive parts run 15-plus years and are costly to move, but no customer is contractually barred from using another foundry.
Confirmed
Customer concentration, stated plainly: the largest customer, Melexis, was 43% of FY2025 revenue; top three were 53%, top five 58%. The quarterly largest-customer share fell from 41% to 35% into Q1 2026. Part of that decline is genuine diversification - customers two through twenty grew revenue 21% quarter-over-quarter - but a good part is automotive destocking, not a deliberate move.
Confirmed
Wide-bandgap revenue reached $15.1 million in Q1 2026, up 152% year-over-year, with silicon-carbide wafer shipments up 195% to 14,300 units. The honest caveat: that is off a depressed base - FY2025 silicon-carbide revenue was $33.8 million, down 34% after an exceptionally strong prior-year first quarter. Wide-bandgap was about 4% of FY2025 revenue.
Confirmed
The AI-datacenter connection is real but thin: silicon carbide serves the 800V-to-48V/12V/6V data-center power conversion chain and solid-state breakers, Navitas is a named silicon-carbide customer, and a chip built on the foundry's technology is used for atomic-clock timing to synchronize GPUs in racks. Global utilization sits in the low 60s percent, on a cost base roughly 70% fixed / 30% variable, so margin recovery depends on higher loading.
Confirmed
Silicon photonics is still pre-revenue: mostly non-recurring engineering today (about $7 million in 2025, roughly 5.5 to 7% of group NRE), developed with named partner Ligentec and inside the EU-funded photonixFAB project. Management guides product revenue - beyond NRE - to around the end of 2027 or 2028, so not yet visible outside NRE. Whether that inflection actually lands is an open question.

Yeah, I want to highlight that X‑FAB is a pure‑play analog and mixed‑signal specialty foundry – process nodes from 1.0 µm down to 110 nm on 150 mm and 200 mm wafers, across six fabs in four countries: Erfurt, Dresden and Itzehoe in Germany, Corbeil‑Essonnes in France, Kuching in Malaysia, and Lubbock, Texas. Does that answer the question?

Yeah. I want to highlight that wide‑bandgap revenue reached $15.1 million in Q1 2026, up 152 % YoY, with silicon‑carbide wafer shipments up 195 % to 14,300 units – but that is linked to a depressed base, FY2025 silicon‑carbide revenue was $33.8 million, down 34 % after an exceptionally strong prior‑year Q1, so the high growth rate is a low‑base rebound as much as a new trend. The AI‑datacenter slice remains thin but growing, with silicon‑carbide used for solid‑state breakers and 800 V‑to‑48/12/6 V conversion and a timing chip that synchronises GPUs. Does that answer the question?

Yeah, the SiC backdrop was soft — I want to highlight wide-bandgap: $15.1M in Q1 2026, up 152% YoY, SiC wafers up 195% to 14,300 — but off a depressed base, FY2025 SiC revenue $33.8M down 34% after a strong prior-year Q1, so growth is a low-base rebound as much as a new trend.

Yeah. I want to highlight that our largest customer, Melexis, was 43% of FY2025 revenue – about $377 million; the top three were 53% and the top five 58%. Into Q1 2026 that share fell from 41% to 35%, which we frame as diversification while customers two through twenty grew 21% QoQ. The fuller reading is that the decline is linked in large part to involuntary automotive destocking at that customer – automotive revenue fell 10% YoY – not purely deliberate diversification. Both readings hold. Does that answer the question?

Yeah, I want to highlight what sits beneath those numbers: we are a pure-play analog and mixed-signal specialty foundry, 1.0 micron down to 110nm on 150mm and 200mm wafers across six fabs in four countries — Erfurt, Dresden, Itzehoe, Corbeil-Essonnes, Kuching, Lubbock.
