ASML Holding NV’s sales to memory chipmakers outpaced those to logic processors for the first time, a landmark shift driven by an artificial intelligence infrastructure buildout that now prizes memory as a critical bottleneck. The Dutch equipment giant reported that 51 percent of its Q1 system sales went to memory customers, a direct reflection of the industry’s scramble for high-bandwidth memory (HBM) to complement AI accelerators from Nvidia and AMD.
"For the foreseeable future, demand will continue to outpace supply," ASML President and CEO Christophe Fouquet said in the company's earnings call. "This creates constraints across end markets from AI to mobile and PCs, which is driving our customers to aggressively add capacity."
The company posted revenue of €8.8 billion for the first quarter, beating the €8.5 billion consensus, and raised its full-year 2026 sales guidance to a range of €36 billion to €40 billion. The growth was powered by its top customers in South Korea (45% of sales) and Taiwan (23%), home to memory makers Samsung Electronics, SK Hynix, and foundry giant TSMC. However, sales to China fell to 19% of the total, down from 36% in the previous quarter, as U.S. and Dutch export restrictions took effect.
Despite the record results and upgraded forecast, ASML’s stock fell 6% following the announcement. The move suggests investors are weighing the impacts of geopolitical restrictions and a valuation that has already priced in substantial growth. The focus now shifts from whether AI demand is strong to how the value is distributed across a supply chain facing new memory-centric constraints and regulatory headwinds.
The AI Memory Bottleneck
The pivot to memory dominance is a direct consequence of the AI boom's second act. While logic chips like GPUs from Nvidia perform the calculations, they are useless without high-speed access to data stored in adjacent HBM stacks. As AI models grow, the demand for this specialized memory—produced by companies like SK Hynix, Samsung, and Micron—has exploded. This has forced memory producers to aggressively invest in the advanced lithography tools needed for next-generation HBM, with ASML being the sole supplier of the most critical extreme ultraviolet (EUV) machines. EUV systems accounted for 66% of ASML's revenue in the quarter.
Valuation and Geopolitical Headwinds
The negative stock reaction highlights the market's high expectations for the semiconductor sector. With ASML trading at a premium valuation, even a strong beat and raise were not enough to push the stock higher. Investors are now focused on new risks. The sharp decline in China sales, a direct result of government restrictions on the export of both EUV and, increasingly, deep ultraviolet (DUV) systems, removes a significant growth market. While demand from other regions is currently filling the gap, the episode underscores the vulnerability of the entire semiconductor supply chain to geopolitical friction. The market is now recalibrating, looking beyond pure growth to assess the sustainability of demand and the emerging risks in a sector at the heart of global technological competition.
