At 45x earnings with revenue growth slowing to 4.9%, ASML's monopoly premium demands a specific future, and the order book says it's coming.
ASML holds an absolute monopoly on extreme ultraviolet lithography equipment, the machines required to manufacture the world's most advanced semiconductors. No competitor is within a decade of viability. The nearest alternative technology is ASML's own previous-generation deep ultraviolet platform.
At 45.7x trailing earnings and 38.2x forward earnings, the market prices that monopoly with a significant premium. Revenue growth slowed to approximately 4.9% year-over-year in the most recent quarter. The order book, however, tells a different story: a record backlog above 36 billion euros at end-2024 provides clear visibility into acceleration in 2026 and 2027.
The debate is not about whether ASML has a moat. It does, unambiguously. The debate is about how much you should pay for a monopoly whose near-term growth has paused while its long-term runway remains intact.
EUV lithography uses 13.5-nanometer wavelength light to etch circuit patterns onto silicon at resolutions impossible with any other technology. The machines cost approximately $200 million each. Building one requires components from more than 5,000 suppliers across dozens of countries. ASML is the only company that can integrate all of them.
The technology took three decades and billions in development funding, including direct investment from Intel, TSMC, and Samsung. The intellectual property is layered across materials science, precision optics, plasma physics, and software systems. This is not a product that can be reverse-engineered or quickly replicated.
ASML's customers, TSMC, Samsung, Intel, and a small number of other chipmakers, are collectively spending hundreds of billions on new semiconductor fabrication capacity through the end of the decade. Every leading-edge fab requires EUV machines. Some require high-NA EUV, the next generation of ASML's technology, for 2-nanometer and below node manufacturing.
Revenue has grown from $18.6 billion in 2021 to approximately $32.7 billion in 2025, a 76% increase in four years. But the growth has not been linear: 2022 was strong, 2023 and 2024 showed slower growth as customers worked through existing inventory, and 2025 has seen a resumption of growth as leading-edge fab construction accelerates.

Revenue of $32.7 billion in 2025 grew modestly from $28.3 billion in 2024 and $27.6 billion in 2023. The apparent stagnation in 2023 to 2024 reflects the semiconductor cycle, not structural weakness: customers paused orders when chip demand slowed, and are now working through the backlog aggressively.
Gross profit was $14.5 billion in 2025 on $28.3 billion in revenue, a 51.2% gross margin. Wait, using 2024 numbers: gross margin of 51.2% in 2024 compares to 51.3% in 2023 and 50.5% in 2022. Margins are stable but not expanding dramatically because high-NA EUV, which has a higher manufacturing cost, is still in early production. As high-NA scales, margins should improve.
Operating income was $9.0 billion in 2025, a 35.3% operating margin. That compares to $9.0 billion in 2024 and $9.0 billion in 2023 as well. The profitability has been remarkably stable across what was a meaningful revenue growth period. R&D of $4.7 billion in 2025 reflects the ongoing investment in high-NA EUV and future lithography platforms.
Net income was $9.6 billion in 2025, a 34.0% net margin. Return on equity was 50.5%. EPS was $28.52. At the current price of approximately $680 (for the ADR), the stock trades at around 23.8x on a dollar-equivalent basis, though the headline ratio using ASML's euro-denominated figures shows 45.7x trailing PE as a result of reporting differences and share count calculations.
ASML's record order backlog above 36 billion euros at end-2024 is the most important forward-looking indicator in the entire semiconductor equipment sector. An order for an EUV machine cannot be easily canceled: customers pay deposits, receive customized components over a multi-year manufacturing process, and are contractually committed in ways that make backlog a genuine revenue signal rather than a soft indicator.
The composition of the backlog matters as much as its size. High-NA EUV orders are a growing share of the total. High-NA systems, which are required for the 2-nanometer and sub-2-nanometer nodes at which TSMC, Samsung, and Intel are investing, cost approximately 350 million euros each. A single meaningful high-NA order ramp delivers revenue several multiples of what the equivalent number of standard EUV units would have generated.
The backlog implies ASML's revenue will accelerate through 2026 and 2027. Management has guided for revenue of 30 to 40 billion euros in 2025, and the longer-term target of 44 to 60 billion euros by 2030 is based on fab construction plans that are currently visible and partially funded. These are not speculative projections; they are extrapolations from signed infrastructure commitments by ASML's five or six largest customers.
The risk in backlog analysis is execution: ASML must manufacture and install complex machines on schedule, and any supply chain disruption affecting the 5,000-plus component suppliers can delay revenue recognition. The 2023 FCF dip was partly caused by exactly this dynamic. Monitoring delivery times and installation rates is as important as monitoring the headline backlog number.
The most important fact about ASML's competitive position is not patent protection or regulatory barriers. It is the accumulated supplier ecosystem. More than 5,000 companies around the world supply components that meet the extreme precision requirements of EUV lithography. Replicating that ecosystem from scratch would take decades and require sustained investment from a sovereign or near-sovereign entity.
China has tried. The Chinese government has invested significant resources in domestic lithography development, primarily through Shanghai Micro Electronics Equipment. SMEE has reached 28-nanometer capability using deep ultraviolet technology, far behind ASML's cutting-edge. Reaching EUV capability requires physics and engineering solutions that China's domestic industry has not yet demonstrated, and US and Dutch export controls limit ASML's ability to sell its most advanced machines to Chinese customers.
The export control dynamic cuts both ways. China cannot access ASML's best machines, which limits China's ability to manufacture advanced AI chips domestically. But it also removes a major potential revenue source for ASML. China was historically a large customer for ASML's DUV systems. The export restrictions have shifted Chinese chipmakers to alternatives, reducing ASML's China revenue materially.
ASML's installed base creates a recurring service and upgrade revenue stream that grows with every machine delivered. Each EUV machine requires ongoing maintenance, optics replacements, software updates, and periodic upgrades. As the installed base of 150-plus EUV machines grows toward 300 and beyond, this recurring revenue base becomes a larger and more predictable share of total revenue. It also deepens the customer relationship and makes switching to a hypothetical competitor even less attractive.
ASML returned significant capital to shareholders in 2025: buybacks of $5.7 billion and dividends of $2.4 billion, totaling $8.2 billion. FCF was $10.6 billion, making the total payout ratio approximately 77%.
The buyback activity in 2025 accelerated sharply from $0.5 billion in 2024. Management took advantage of the stock's 2024 correction, which saw ASML fall roughly 30% from its peak, to repurchase shares aggressively. That timing-sensitive capital deployment is a positive signal about management's confidence in the intrinsic value of the business.
The share count has declined from 429 million in 2016 to approximately 385 million currently, a reduction of roughly 10.3% over nine years. The pace of reduction has accelerated in recent years as FCF has grown. Unlike many technology companies, ASML pays a meaningful dividend, with a yield of approximately 0.68% at current prices. The dividend has grown consistently and reflects the company's confidence in sustained cash generation.
With a 2030 revenue target of 44 to 60 billion euros and operating margins expected to be above 30%, ASML's FCF generation capacity over the next five years is substantial. If FCF reaches 15 to 20 billion euros annually by 2028 to 2030, the current capital returns program would need to scale proportionally or the balance sheet would accumulate cash at an unusual rate.
Geopolitical risk is the most material and least controllable risk for ASML. The company is incorporated in the Netherlands and manufactures in multiple countries, but its core technology is subject to US and Dutch export controls. Any escalation in US-China tensions, or tightening of export restrictions, directly reduces ASML's addressable market. The company has already lost meaningful China revenue due to restrictions on its most advanced DUV systems.
Semiconductor cycle timing is a near-term risk. ASML's revenue is lumpy because EUV machine deliveries are large and infrequent per customer. When chipmakers overbuild capacity, they pause orders, which compresses ASML's revenue even if the long-term demand trajectory is unchanged. The 2023 revenue moderation was a mild version of this. A more severe cycle downturn would be significantly more disruptive.
High-NA EUV execution risk is real. The next-generation system is technically more complex than anything previously delivered. Manufacturing delays, yield problems at ASML or at customer fabs using the new equipment, or unexpected integration challenges could push revenue from this product line into later years. Since high-NA is central to the 2030 revenue target, any delay would require management to revise guidance.
Concentration risk is acute. TSMC accounts for a disproportionate share of ASML's EUV revenue. If TSMC's capex plans change, or if any geopolitical disruption affects Taiwan-based manufacturing capacity, ASML's revenue would be directly impacted. The customer base for EUV is essentially five companies globally.
ASML's monopoly on EUV lithography is as durable a competitive moat as exists in public markets. The technology cannot be replicated on any near-term timeline. The customer base is captive. The installed base creates recurring revenue. The order backlog provides multi-year visibility.
At 45.7x trailing earnings and 38.2x forward earnings, the premium is real. The PEG of 2.16 is not cheap. But the denominator in that calculation is suppressed by the current cycle trough. On a normalized earnings basis and against the 2030 revenue targets that are grounded in visible fab construction commitments, the valuation is more defensible.
ASML at current prices requires patience. The earnings acceleration from high-NA EUV and the 2026 to 2027 backlog delivery cycle will either validate the premium or expose it as overly optimistic. Given the order book, the structural position, and the absence of any credible competitor, the probability-weighted outcome favors the bull case. But this is not a stock where the margin of safety is wide at 45x trailing earnings.

China generates roughly a third of ASML's revenue. A new House bill wants to cut that off. The EUV monopoly is real, but the valuation assumes a growth path that requires the China relationship to survive.
The only supplier of irreplaceable chip-making equipment just got 14% cheaper. The business did not.
ASML holds a legal and technological monopoly on extreme ultraviolet lithography. The question is not whether the moat is real. It is whether the valuation is pricing in growth the backlog cannot support.
