Applied Materials Faces China Challenge Amid Domestic Chip Mandate

**Implied Volatility / Movement:** China's directive for semiconductor manufacturers to utilize at least 50% domestically produced equipment for new capacity is intensifying challenges for foreign equipment suppliers like Applied Materials. This policy directly pressures the company's substantial revenue stream from China, which represented 26.4% of its total revenue in the last reported quarter.

## Catalyst Analysis: China's Domestic Equipment Mandate

On August 26, 2026, reports surfaced detailing China's new policy mandating that semiconductor manufacturers use a minimum of 50% domestically produced equipment when establishing new production capacity. Fab projects failing to meet this threshold risk regulatory disapproval, though exceptions exist if no suitable Chinese tools are available. This directive explicitly favors domestic suppliers such as Naura Technology and AMEC, while presenting a more complex operating environment for foreign entities like Applied Materials.

## Impact on Semiconductor Equipment Sector

### Winners, Losers & Uncertainty

The new Chinese policy directly impacts Applied Materials' business, as China constituted 28.0% of its total revenue in a prior period and 26.4% in the most recent quarter. While the company's revenue from China declined 6.6% year-over-year to $2.087 billion in its fiscal first quarter of 2026, it still represented 29.9% of its total revenue for that period. The introduction of domestic immersion DUV lithography systems by Shanghai Aishengna Electronic Technology Group, while not directly competing with Applied Materials' product lines (which include deposition, etch, and processing systems), indirectly increases the risk. If these domestic lithography systems prove commercially viable, they could enable Chinese fabs to increase their reliance on domestic components across a broader range of manufacturing stages. This could gradually reduce Applied Materials' addressable market in China over the coming years, despite the immediate impact on earnings being assessed as limited for 2026.

### Risk Watch — legal/timeline

While the immediate impact of new domestic DUV systems on Applied Materials' earnings in 2026 is expected to be minimal, the long-term implications are significant. The combination of China's domestic equipment mandate, the growth of local equipment companies, and the expansion of major fabs like CXMT and SMIC could steadily diminish Applied Materials' market share in China over time.
