The US government, via Commerce Secretary Howard Lutnick, has expressed concern that an ASML EUV lithography system may have been shipped to China in violation of export controls, according to Bloomberg. ASML vehemently denies the allegation, stating it has never shipped an EUV machine to China and that it tracks all 314 active and 26 retired EUV systems globally, with none located in China (Tom's Hardware). The company notes that EUV machines are too large and complex to be moved without ASML's direct involvement and that they continuously communicate with ASML. Despite the denial, the U.S. administration claims to have information about associated equipment exports. This geopolitical friction introduces regulatory risk for ASML, potentially leading to tighter export controls or reputational harm that could impact future sales and investor confidence. Separately, a positive technology milestone was achieved by imec, ASML, and TSMC in 2D transistor scaling (Tom's Hardware), but the immediate market focus is on the export control threat. Spillover effects could affect Chinese foundries like SMIC if sanctions intensify, as well as other semiconductor players reliant on ASML tools.
