Disclosure
Blue identifies disclosed figures and shares calculated from disclosed revenue; amber and ≈ identify approximate ASTRIA amounts converted from disclosed shares. Calculated and estimated values retain methods and sources. Anonymous customers stay anonymous. A named relationship does not establish its revenue. Annual, quarterly and YTD periods, customer headquarters, shipment destinations and usage locations can differ.
Undisclosed customer revenue stays unavailable. Estimates are neither issuer-confirmed revenue nor forecasts. · 2026-09-09

Comparison rules & source notes
This snapshot combines official IR materials and SEC disclosures. Fiscal calendars, acquisitions, divestitures and reclassifications affect comparability.
- Year-ago revenue uses the issuer rounded earnings-release amount.
- Revenue, wafer revenue share and physical wafer shipments remain separate. Foundry operating estimates are available in the dedicated foundry desk.
Quarterly cash flows and Q4 statements may use cumulative-report differences. Per-share values are never calculated by subtracting annual and nine-month EPS. Sources and calculation inputs are retained in JSON / CSV.
