Summary: Applied Materials stock plunged in mid-day trading after a report said a Shanghai-based, state-backed Chinese company has started mass production of homegrown immersion deep ultraviolet (DUV) lithography equipment. The news triggered a widespread decline across the chip equipment sector, pressuring major U.S. suppliers and a leading Dutch peer.
Shares of Applied Materials fell 7.1% in mid-day trading following the report. The story set off a sector-wide reaction that also pushed Lam Research and KLA Corp sharply lower, while ASML, the Dutch supplier long synonymous with advanced lithography, was similarly hit.
The development carries particular weight for Applied Materials because China accounts for a meaningful share of the company’s revenue. The firm already faces an anticipated revenue headwind of $600 million to $710 million in fiscal 2026 related to U.S. export control measures. Market participants interpreted the Chinese mass-production milestone as a reinforcement of the risk that Beijing’s drive toward a self-sufficient semiconductor supply chain could gradually reduce demand for Western-made chipmaking equipment.
Reports note that the domestically produced immersion DUV machines have not been described as matching the precision of leading foreign models at this stage. Nevertheless, the capacity to mass-produce such tools domestically represents a material step in China’s localization effort, a development investors viewed as strategically significant for the industry’s long-term competitive landscape.
The broader market provided limited support for chip-equipment names on the day. The NASDAQ declined 0.4% while the S&P 500 slipped 0.2% as technology stocks led a modest retreat. Investors were also in a cautious stance ahead of a Federal Reserve policy announcement expected later in the week, a factor that added to the risk-off tone in semiconductor-related shares.
Applied Materials had already endured a series of sharp pullbacks through July as the semiconductor group worked through the effects of a record-breaking first half of the year. In an intraday snapshot included with market data, several ticker moves were displayed: US500-0.2% AMAT-6.32% LRCX-7.24% KLAC-5.18% IXIC-0.47% ASML-7.2%.
Key takeaways
- Mass production of domestically developed immersion DUV machines in China prompted a sharp selloff in chip-equipment stocks.
- Applied Materials is exposed to China, amplifying concerns about potential long-term erosion of demand for Western equipment.
- Wider market caution ahead of a Federal Reserve policy announcement contributed to the sector’s decline.
Risks and uncertainties
- Uncertainty over how quickly China’s domestically produced DUV tools could substitute for Western equipment and affect long-term purchasing patterns in the Chinese market.
- Existing U.S. export control restrictions are already expected to create a $600 million to $710 million revenue headwind for Applied Materials in fiscal 2026.
- Near-term market volatility driven by macro events, such as the Federal Reserve policy announcement, which may amplify sector moves.
The market reaction to the report served as the immediate catalyst for the day’s decline, reviving longstanding concerns about access to the China market and the effects of export controls on Western chip-equipment suppliers. These strategic and policy-driven risks overshadowed the company’s otherwise positive operational signals, including a raised full-year outlook for semiconductor equipment growth that had been part of its recent communications.
