The AI infrastructure boom continues to drive extraordinary demand across the semiconductor industry, benefiting both ASML and TSMC. While both companies are key enablers of the AI revolution, they occupy different positions in the value chain. ASML manufactures the lithography systems used to produce advanced semiconductors. Its most important products are Extreme Ultraviolet (EUV) and Deep Ultraviolet (DUV) lithography machines, which are essential for manufacturing cutting-edge chips. TSMC, the world’s largest semiconductor foundry, uses these tools to manufacture chips designed by customers such as Nvidia, Apple and AMD. The relationship is highly symbiotic: ASML provides the equipment, while TSMC turns that equipment into the world’s most advanced semiconductors. Both companies are experiencing strong financial momentum from AI-related demand. ASML reported record revenue of €11.7 billion with gross margins of 57.5%, while TSMC delivered 41% year-on-year revenue growth, alongside gross margins of 66.4% and operating margins of 58.7%. These results reflect surging demand for AI accelerators, high-performance computing chips and memory infrastructure. Despite unprecedented demand, management teams remain disciplined in their expansion plans. The semiconductor industry has historically suffered from periods of overbuilding, followed by painful downturns and underutilized facilities. Having experienced previous cyclical slowdowns, both companies are taking a more measured approach. ASML is increasing output primarily through manufacturing optimization rather than large-scale factory expansion. ASML are targeting a 30% capacity expansion for 2027 and an additional 30% capacity expansion for 2028. TSMC continues to invest aggressively, with planned capital expenditure of $60-64 billion. Management for ASML and TSMC emphasized that expansion remains tied to long-term customer demand rather than short-term enthusiasm. One of the most important developments at TSMC is the rapid adoption of its N2 (2-nanometer) technology – the most advanced semiconductor on the market. N2 contributed 8% of wafer revenue during the quarter, up from just 3% in the previous quarter, highlighting strong customer adoption. Capacity is expected to more than double in 2027, making N2 an increasingly significant contributor to future growth. It is unclear how quickly potential competitors can catch up to ASML and TSMC and both these businesses are not complacent of their dominance, by continuing to innovate and build more scale. The key takeaway is that both companies remain confident in the AI buildout but are prioritizing sustainable growth over aggressive capacity additions. That discipline may prove as important as the AI opportunity itself. |
