#ASMLTSMCQ3EarningsSoon ASML and TSMC Earnings: The Next AI Boom Depends on Supply Chain Execution, Not Just Demand
The AI semiconductor story is entering a new phase. Demand for AI chips remains a major industry driver, but investors are increasingly focused on a more difficult question: Can the semiconductor supply chain deliver enough advanced equipment, manufacturing capacity, and packaging solutions to support the next wave of AI growth?
ASML and TSMC will be central to this discussion as investors examine their October 14–15 earnings updates. Their results could reveal whether the industry is scaling efficiently or approaching new capacity constraints.
1. ASML: Equipment Orders Will Reveal the Strength of Future Investment
ASML plays a critical role in advanced semiconductor manufacturing by supplying lithography equipment, including extreme ultraviolet (EUV) systems used to produce leading-edge chips.
The company’s challenge is to expand manufacturing capacity while meeting increasingly demanding customer requirements.
In its previous outlook, ASML planned to increase its 2026 low-NA EUV production capacity of approximately 65 systems by 30% in 2027, while exploring another potential 30% increase for 2028. Its DUV immersion capacity was also expected to rise approximately 30% in 2027 from around 130 systems in 2026.
These figures represent capacity plans, not guaranteed deliveries.
I will focus on order intake, equipment shipments, customer commitments, and service revenue. Strong orders would support the view that chipmakers are preparing for sustained AI-related investment. However, weaker bookings could raise questions about the timing of future spending.
2. TSMC: Advanced Packaging Could Become the Critical Bottleneck
TSMC occupies another essential position in the AI supply chain. It manufactures advanced chips and provides packaging technologies that integrate complex processors with high-bandwidth memory.
One technology attracting particular attention is Chip-on-Wafer-on-Substrate (CoWoS), which helps combine multiple components into high-performance semiconductor packages.
As AI accelerators become more sophisticated, packaging capacity becomes increasingly important. Even when chip designs and wafer production are available, insufficient packaging capacity can delay finished products.
During TSMC’s October 15 earnings update, I will watch for details about CoWoS expansion, advanced-node demand, customer production commitments, and the pace at which new capacity becomes operational.
The key question is whether packaging capacity can grow alongside wafer production without creating additional delays or excessive costs.
3. Capital Expenditure: Opportunity or Financial Risk?
TSMC raised its 2026 capital-expenditure forecast in July to $60 billion–$64 billion, compared with its previous range of $52 billion–$56 billion. Its investment plans also include expanding U.S. manufacturing operations through its Arizona facilities.
This spending reflects the scale of the semiconductor industry's ambitions, but large investments do not automatically guarantee attractive returns.
Factories, equipment, and packaging facilities require substantial upfront capital. Their profitability depends on utilization rates, customer demand, production efficiency, and pricing power.
I believe investors should examine whether planned spending is supported by visible demand rather than assuming AI growth will remain exceptionally strong indefinitely.
4. Three Signals That Could Move Semiconductor Stocks
The bullish scenario would include strong ASML bookings, continued progress in TSMC's packaging expansion, and confident guidance supported by sustainable customer demand.
The cautious scenario would emerge if equipment orders weaken, capacity expansion moves ahead of actual demand, or management highlights rising costs and pressure on margins.
A third possibility is that both companies report solid results but their shares experience volatility because investors have already priced in ambitious AI growth expectations.
My View: Follow the Entire Supply Chain
For October 14–15, I will compare ASML's order momentum and production plans with TSMC's advanced-node outlook, packaging capacity, and capital-spending commitments.
These indicators can provide a clearer picture of the industry's health than revenue growth alone.
The next phase of the AI boom will depend not only on how many chips the world wants, but also on how efficiently the industry can manufacture, package, and deliver them.
Strong AI demand creates the opportunity. Execution, capacity discipline, and investment returns will determine whether that opportunity becomes sustainable profit.
