Foundry automotive revenue mix measures the share of foundry revenue attributed to automotive applications under the issuer's platform classification.

TSMC reported that automotive represented about 5% of 2025 revenue.

Five percent sits inside a much larger platform mix

The same 2025 platform disclosure put HPC at 58% and smartphones at 29%. The 5% automotive share was therefore much smaller than either of TSMC's two dominant platforms.

That does not make automotive economically interchangeable with another 5% category. Automotive chips can use different process nodes, qualification requirements, product lives, and pricing structures.

Equal revenue shares can hide different manufacturing demand

Automotive and Foundry IoT Revenue Mix each represented about 5% of 2025 revenue, but equal shares do not imply equal demand cycles or equal wafer requirements.

Use Process Node Revenue Mix to separate application exposure from the node mix used to manufacture those applications.

Watch mix changes in percentage points

A move from 5% to 7% would be a two-point shift in company revenue mix, not simply a 40% increase in the economic importance of the platform. Mix should be analyzed alongside the absolute company revenue base.

Where this concept fits

Platform and process-node mixCurrent relationship
HPC, smartphone, IoT, automotive, and digital-consumer-electronics revenue mix show where foundry demand originates. Advanced-technology wafer revenue mix and process-node revenue mix show which manufacturing generations monetize that demand without treating end-market categories as process nodes.

Customer concentration and manufacturing breadth
Largest, second-largest, and top-ten customer concentration show dependence on major customers, while customer count, product count, and process-technology count show the breadth of the manufacturing ecosystem. Breadth does not negate concentration because a small number of customers can still drive most revenue.

Capacity, utilization, output, pricing, and yield
Annual 12-inch-equivalent capacity and wafer manufacturing capacity describe production scale, capacity utilization shows how much of that scale is being used, wafer shipments measure output, wafer average selling price measures realized pricing, and manufacturing yield indicates how effectively processed wafers become usable product.
