Investors weighing the artificial intelligence supply chain are looking closely at two companies that sit on different rungs of the semiconductor value chain: Taiwan Semiconductor Manufacturing and ASML. Both have benefited from strong demand for advanced chips, but their latest operating signals point to distinct drivers—TSMC through manufacturing scale and leading-edge process ramp, and ASML through lithography equipment that enables the fabrication of smaller, more complex designs.
Key takeaways
- Manufacturing momentum: TSMC reported second-quarter revenue of $40.2 billion, up 33.7% year over year, with a net profit margin of 55.6%.
- Equipment demand supports advanced nodes: ASML delivered 86 new lithography units and five used units in the second quarter, lifting revenue to 9.32 billion euros.
- Catalyst: TSMC’s continued execution on 2-nanometer process commercialization and ASML’s sustained traction in advanced logic and memory are central to the outlook.
- Implication for AI exposure: TSMC offers more direct leveraged exposure to chip production volume and leading-edge node share, while ASML provides exposure to capex devoted to keeping advanced processes on track.
- Near-term watch: Investors are likely to monitor how fast 2-nanometer ramps translate into additional revenue mix and how ASML’s order visibility evolves with customer capacity expansion.
What drove the move
The case for both stocks rests on a common theme: AI-related investment is pulling forward demand for advanced logic and memory, which in turn requires both manufacturing capacity and cutting-edge lithography tooling.
According to the company, TSMC is strengthening its position at the leading edge of the foundry market. The report cited an estimated global foundry share of 73%, up from 69% in the fourth quarter of 2024. TSMC also highlighted technology depth and production breadth, noting it fabricated more than 12,600 different products in 2025 using 305 process technologies.
On the equipment side, ASML benefits as foundries and chip designers move to smaller geometries and more complex chip architectures. The company’s technology mix matters because extreme ultraviolet (EUV) lithography—using mirrors rather than lenses—enables steps that deep ultraviolet (DUV) tools cannot. ASML reported that in the second quarter it sold 86 new lithography units and five used units, compared with 67 new machines and 12 used units a year earlier.
Market reaction and operating signals
While the original article does not provide specific share-price moves tied to the reporting dates, the underlying operating results point to why investor focus remains elevated.
For TSMC, the financials cited show a strong growth profile: second-quarter revenue of $40.2 billion, up 33.7% year over year, and a net profit margin of 55.6%. The business mix is also shifting toward more advanced process technologies. The article said that in recent quarters, 3-nanometer and 5-nanometer technologies together generated more than 60% of revenue, and that revenue for the 2-nanometer process was recorded for the first time in the most recent quarter.
The report also included process technology share updates sourced from TSMC, showing higher contribution from advanced nodes in the latest quarter. Specifically, it listed 3-nanometer share at 30% for Q2 2026 (up from 24% in Q2 2025 and 15% in Q2 2024), and 5-nanometer share at 33% for Q2 2026 (down from 36% in Q2 2025 and 35% in Q2 2024). Meanwhile, 2-nanometer share rose to 3% in Q2 2026 from 0% in the earlier periods shown.
ASML’s financial performance reflected improved unit demand as well. The report stated second-quarter revenue rose to 9.32 billion euros, up 11% year over year, while net income increased to 2.91 billion euros (up 5.8%). Gross margins were reported at 54%.
Why investors compare TSMC and ASML
TSMC is positioned as the bottleneck provider for advanced chip manufacturing, with the article describing it as the world’s largest semiconductor chip manufacturer. The report attributed its strength to process leadership, including the ramp of 2-nanometer technology and the scale of its advanced node production. It also pointed to a planned manufacturing buildout: TSMC announced a $100 billion expansion of its Arizona facilities, aimed at supporting advanced packaging fabs and its 2-nanometer processing technology.
ASML, by contrast, is a critical enabler of semiconductor scaling. The company sells lithography tools that foundries use to pattern increasingly tiny features. In the article’s framing, the relationship between ASML and TSMC is direct: ASML’s systems are essential for manufacturing flows that require the precision of EUV. The report also quoted ASML’s CEO, Christophe Fouquet, saying ongoing AI-related investments and continued progress in AI technologies are driving demand for advanced logic and memory chips. Fouquet added that customers are accelerating capacity expansion plans, leading to longer-term product commitments that increase ASML’s visibility.
Bigger picture for the AI semiconductor supply chain
For investors, the distinction between these two companies can matter as AI capex cycles evolve. TSMC’s results indicate both demand strength and execution on advanced nodes, including early monetization of 2-nanometer output. ASML’s unit sales and profitability suggest that customers continue to fund the equipment needed to keep advanced manufacturing on schedule.
Looking ahead, investors are likely to focus on how quickly 2-nanometer volumes translate into a larger share of revenue, whether advanced node share continues to rise, and how ASML’s delivery pace and order visibility track with semiconductor manufacturers’ capacity plans.
What to watch next: upcoming quarterly updates from TSMC and ASML, signals on the rate of 2-nanometer adoption, and any further evidence of sustained AI-driven capex by major chip manufacturers.
