VLSI ASTRIA · ESTIMATES

Estimates for undisclosed measures

These estimates combine public anchors with explicit analyst assumptions. Centers are conditional model outputs; ranges show sensitivity to those assumptions. They are not statistically validated confidence intervals or issuer disclosures.

Estimated measure / BasisCenterSensitivity rangeUnit
Implied wafer shipmentsRevenue-implied output; not physical 300mm wafer counts~148.8100.8209.1thousand 300mm-equivalent wafers
Capacity-weighted utilization estimateAssumed capacity-area weights across disclosed fab-utilization ranges~85.377.390.3percent

Wafer output mix · estimated

Revenue share is divided by an assumed relative wafer price, then converted to physical count and area. 300mm / 200mm ASP ratio: 2.5× (1.54×). This ratio is an analyst assumption, not an observed quote.

Physical wafer count~21.1%5.950%~78.9%
Wafer area equivalent~37.5%12.369.2%~62.5%

Only the two modeled wafer diameters are included. Intel uses a fixed 300mm-only logic-wafer assumption; a 100% modeled result does not establish a disclosed company-wide mix.

Formulas, assumptions & sensitivity bounds

astria-foundry-sensitivity-1.0 · 2026-09-09 · Not statistically calibrated. Sensitivity ranges reflect explicit modelling assumptions, not confidence or prediction intervals. No validated accuracy claim.

For free categories: share = weight / sum of free weights × unallocated revenue share. The minimum uses this category’s low weight against other categories’ high weights; the maximum reverses them. Fixed external-revenue shares are preserved. Node and diameter models describe wafer revenue, while the end-market model follows its stated company scope.

Tower technology-platform revenue estimate

Consolidated wafer technology revenue; specialty platforms are not nominal node sizes. Scenario-conditioned allocation. Quantitative weights are ASTRIA judgement, not measured capacity or statistically fitted estimates. Product announcements constrain the eligible families but do not identify their shares.

tower wafer-diameter revenue estimate

Wafer-manufacturing revenue only; excludes non-wafer services. A physical count cannot be read from revenue share. The separate output-mix estimate also requires a 300mm/200mm ASP-ratio assumption. ASTRIA diameter-revenue assumption constrained only by the disclosed footprint; no equal weighting of fabs.

Implied wafer shipments

Revenue (USD m) × 1000 × wafer-service fraction ÷ assumed USD per 300mm-equivalent wafer

ASP and wafer-service fractions are explicit, uncalibrated assumptions. Intel transfer pricing is not an external market ASP. Revenue recognition, work in progress and yield can disconnect these implied volumes from shipments.

Capacity-weighted utilization estimate

300mm capacity weight × 300mm utilization + remaining weight × 200mm utilization

Fab capacity weights and the 300mm numerical range are judgement assumptions. The issuer reports individual fab utilization, not this weighted company-wide figure.

}

Physical 300mm count share = R300 / (R300 + ASP ratio × R200). Area share weights each 300mm wafer by 2.25 relative to a 200mm wafer. No yield or inventory adjustment is identified.
