ASML remains the semiconductor industry’s ultimate choke point. Its extreme ultraviolet (EUV) lithography tools—and the first wave of High-NA EUV systems—sit at the core of every leading-edge roadmap. As AI servers devour ever more compute and memory, the number of EUV layers per wafer continues to climb, reinforcing ASML’s pricing power and strategic centrality.

2025 has underscored that position. Execution stayed firm through mid-year, services revenue provided a durable buffer, and customers pressed ahead with node transitions even as export controls and supply-chain wrinkles persisted. The next catalyst is near: Q3 results this week.

What’s New in 2025

High-NA EUV moves from promise to placements. First EXE systems have been placed at early adopters, with initial learning focused on overlay, dose stability, pellicle durability, and tool productivity. The 0.55 NA optics aim to shrink features further and reduce costly multi-patterning at sub-2nm nodes.
Installed base monetization. Services, software, and throughput upgrades have matured into a multi-billion-euro annuity, smoothing the inherently lumpy tool cycle.
Policy still a swing factor. Dutch and U.S. export regimes continue to constrain certain China shipments, creating quarter-to-quarter noise but not changing the longer-term thesis that leading-edge logic and HBM drive secular demand.

Q3 2025 Preview — What to Watch on Wednesday

ASML is slated to report Q3 on Wednesday, October 15 in the morning (CET). Management has guided to net sales of €7.4–€7.9 billion and gross margin of 50–52%, implying a modest sequential step-down from Q2’s outperformance but still a healthy print in the context of strong AI-led demand.

Street expectations cluster near the top of that range on revenue and call for solid profitability, with the mix between tools and services a key determinant of the final gross margin. The setup frames Q3 as a “normalization” quarter rather than a pivot.

Earnings Checklist

EUV & High-NA cadence: Investors will look for incremental color on High-NA qualification timelines, early productivity data, and additional placements, plus commentary on EUV layer intensity at N3/N2-class nodes.
Gross margin drivers: The guide (50–52%) suggests mix and start-up costs are the swing variables. Watch for throughput upgrades, installed-base services, and any edge from software/computational lithography.
Demand signaling vs. bookings optics: Management has de-emphasized quarter-to-quarter bookings volatility this year; multi-quarter capacity plans from top logic and HBM customers are the better forward indicator.
China and licensing: Any update on export approvals, shipment timing, and regional mix will shape Q4 and 2026 visibility.
Cash returns and capex: With margins structurally high, commentary on buybacks, dividends, and supply-chain investments (optics, modules, service capacity) will round out the capital-allocation picture.

Business Drivers to Watch Beyond Q3

AI server capex remains the core engine. Every incremental GPU rack drives upstream wafer demand, lifting EUV layers and favoring ASML’s most advanced tools.
High-NA learning curve. Successful production proof points unlock a multi-year replacement and add-on cycle across leading customers.
Customer concentration risk. A handful of mega-fabs still account for the bulk of EUV demand; node slippages or capex pauses would ripple through shipments.
Cycle sensitivity at mature nodes. DUV and services tied to autos/industrial/handsets remain exposed to macro swings even as AI offsets at the leading edge.

Investment View (Qualitative)

ASML’s moat is technological (EUV/High-NA), ecosystem-embedded (resists, masks, EDA, computational lithography), and contractual (multi-year commitments). With 2025 tracking to double-digit growth and structurally high gross margins, the debate hinges on:

High-NA commercialization cadence (how quickly tools reach production-grade productivity),
durability of AI-led capex (particularly the balance between GPU, HBM, and logic node transitions), and
policy ceilings (the extent to which export controls cap near-term addressable demand).

If Q3 lands within guidance and management reiterates full-year guardrails while adding High-NA proof points, the read-through into Q4 should be constructive.

Conclusion

ASML is still the rare hardware franchise with both scarcity value and pricing power at the heart of the compute build-out. Q3 is less about the exact euro tally and more about validating the High-NA ramp, confirming EUV mix resilience, and gauging policy friction. Clear progress on those fronts would reinforce the case for continued compounding through both tool shipments and a growing services annuity into the sub-2nm era.

FAQ

When are Q3 results expected?
Wednesday, October 15, 2025 in the morning (CET), followed by the investor call the same morning.

What has management guided for Q3?
Net sales of €7.4–€7.9 billion and gross margin of 50–52%.

What are the key swing factors for the print?
High-NA/EUV cadence, tools vs. services mix (gross margin), and any shift in export-license timing or regional mix.

Why does High-NA matter so much?
Its 0.55 numerical aperture enables tighter resolution and fewer multi-patterning steps, targeting better yields and lower cost per transistor at sub-2nm nodes.

How exposed is ASML to China today?
China remains a meaningful market for certain DUV tools and services, but licensing restricts shipments of EUV and some advanced DUV systems, making quarterly phasing sensitive to approvals.
