China's Semiconductor Equipment Companies Gain Share Despite U.S. Sanctions

Chinese vendors reached 6.5% of the $41.4 billion global WFE market in 2025, up from 5.6% in 2024 and 1.2% in 2021, signaling continued domestic share gains in China. U.S. export controls remain the key risk, with ASML estimating a 10-15% hit to China sales and broader pressure on AMAT, LRCX, and TEL as DUV restrictions reduce downstream etch and deposition demand. The article also highlights uneven stock performance, with Lam up 258.2% over the past year versus 158.0% for Applied Materials and 113.6% for ASML.

Analysis

The key takeaway is not that China is displacing the global tool oligopoly, but that it is compressing the addressable China market for the non-China incumbents exactly as WFE growth is normalizing. That creates a second-order earnings risk: the high-multiple names with outsized China mix will likely see revenue growth decelerate faster than consensus even if global WFE stays healthy, because the incremental dollar in China is increasingly captured by lower-end domestic suppliers rather than the leaders.

The bigger structural winner is the Chinese supply chain beyond the headline lithography restriction. Every time China is forced to substitute DUV for EUV, the bill of materials shifts toward more etch, deposition, cleaning, and metrology intensity, but not necessarily toward the same foreign vendors. That means the “sanctions help equipment” argument is incomplete: it helps the tool stack in aggregate, while accelerating localization of the non-litho steps where domestic vendors are already gaining share. Over 12-24 months, this is a margin headwind for AMAT/LRCX/ASML in China and a share tailwind for ACMR/AMEC/NAURA-type domestic suppliers.

The market is also misreading the duration of the ASML/AMAT rerating. If investors are extrapolating one more year of China demand into 2026, they are likely too optimistic: the policy regime has moved from node-specific to function-specific restrictions, which is harder to workaround and more damaging to the multiplier effect in mature-node production. KLA is the relative defensive winner because yield control becomes more valuable as customers substitute around constraints, but even there the upside is more defensive resilience than true acceleration.

The contrarian view is that the selloff risk is not in gross China revenue, but in mix and cadence. The most vulnerable setup is a surprise pause in Chinese capex hoarding once inventory buffers normalize, which would create a 2-3 quarter air pocket in orders before domestic substitution fully offsets it. That sets up a tactical long/short opportunity around China exposure rather than a blanket bearish call on the whole semi-equipment complex.

Key Decisions for Investors

• Short AMAT vs long KLAC for 3-6 months: AMAT has the worse China mix/earnings sensitivity, while KLAC is structurally protected by the rising yield-intensity of advanced and workaround-heavy manufacturing.
• Reduce or hedge ASML into strength with put spreads 6-9 months out: the risk is not existential share loss, but a slower China sales trajectory that can compress multiple expansion if the market has priced in a durable DUV replacement cycle.
• Long ACMR or a basket of China domestic equipment names vs short AMAT/LRCX in a relative-value pair for 6-12 months: domestic substitution should continue to capture incremental China spend at mature and mid-critical nodes.
• Use LRCX strength to fade beta: despite near-term operating momentum, it remains exposed to the most policy-sensitive part of the etch/deposition stack; consider trimming after rallies rather than chasing upside.
• Watch for a 2-quarter order inflection in China-facing guidance; if capex hoarding normalizes, expect the first negative revision cycle to hit non-China leaders before domestic vendors fully scale to offset it.
