What to know
- ASML reported €32.7 billion in 2024 sales and guided 2026 revenue to €34–39 billion — a step-up that implies its order book is filling faster than consensus expected.
- Japan is pouring subsidies into Rapidus, a new AI chip fab that can't exist without ASML's tools — locking in multi-year demand most investors aren't pricing.
- TSMC reports the day after ASML; back-to-back results will tell us whether the AI chip boom is accelerating or stalling.
Every advanced chip inside your phone, your laptop, and every AI data center on the planet was printed by the same machine. Not the same type of machine — literally the same company's machine.
ASML, a Dutch company most people outside tech have never heard of, builds the only equipment on Earth that can etch transistors small enough for cutting-edge processors. There is no second source. No alternative. No close competitor.
That makes ASML one of the most powerful monopolies in the world — and on Tuesday, it reports earnings. The results won't just tell us about one company. They'll tell us how fast the entire AI chip buildout is moving, who's buying, and where the bottlenecks are tightening.
Let's trace the dominoes.
Every advanced chip inside your phone, your laptop, and every AI data center on the planet was printed by the same company's machine.
What just happened
ASML posted €32.7 billion in total sales for fiscal 2024, netting €9.6 billion in profit. That alone is impressive for a company that sells machines costing hundreds of millions of dollars each.
But the forward-looking numbers are what matter right now. ASML guided 2026 revenue to €34–39 billion, with gross margin (revenue minus the direct cost of goods, as a percentage) between 51% and 53%. That's a meaningful step up.
The stock has responded. ASML rose roughly 12% over the past week through mid-April and nearly 7% over the past month, pushing the market cap (the total value of all its outstanding shares) to roughly $580 billion. The earnings call lands on April 15 — right at the start of what's shaping up to be a pivotal earnings week, with Goldman Sachs and JPMorgan also reporting.
Meanwhile, Japan announced substantial new subsidies for Rapidus, a government-backed AI chip venture that depends on ASML's lithography tools. More on that in a moment.
First domino: ASML's monopoly — the only printing press in town
Without access to EUV lithography, fabs simply cannot produce chips at the most advanced process nodes. These machines are among the most complex ever built, requiring decades of R&D investment to develop.
The stock trades at a trailing P/E (how many years of past earnings the stock currently costs) of roughly 51. That looks expensive until you consider: the company has zero direct competitors.
The premium valuation makes sense because of the monopoly. No competitor is within years of matching EUV technology. The physics is the moat. A laser fires at molten tin droplets 50,000 times per second to create EUV light. That light then passes through the most precise mirrors ever made. Nobody else has figured out how to do this at production scale.
But ASML doesn't exist in a vacuum. Its biggest customer is about to report, too.
Second domino: TSMC — the demand signal hiding in plain sight
TSMC reported strong March sales, with AI chip demand booming ahead of its Q1 results due April 16 — one day after ASML reports.
This back-to-back schedule creates a rare information cascade. ASML's higher guidance signals that its customers are expanding capacity. When those foundries then confirm strong sales, it validates the entire chain.
Here's what most investors miss: TSMC's advanced packaging capacity — specifically its CoWoS platform used to stack AI chips — is the binding constraint on Nvidia's shipments right now. That means TSMC isn't just buying more EUV machines to print more transistors; it's expanding the entire facility footprint around those machines. ASML's order book likely understates true demand because TSMC's packaging bottleneck limits how fast it can absorb new lithography tools. Watch TSMC's capex guidance on Wednesday. In the past, it has led ASML's order intake by one quarter. Right now, the gap between TSMC's capex growth and ASML's bookings is unusually wide.
But the demand story isn't just about existing customers. A brand-new player is entering the game.
Third domino: Japan's Rapidus bet — a new country joins the ASML dependency list
Japan announced big new subsidies for Rapidus, a government-backed venture trying to build cutting-edge AI chips at home using ASML's advanced lithography systems. This reflects a broader global push by nations to secure domestic capacity in next-generation chips — and ASML sits at the center of every project.
For ASML, every new government-backed fab is a locked-in, multi-year revenue stream. These projects take years to build and equip, creating visibility into future orders that most tech companies can only dream of. ASML's 2026 revenue guidance of €34–39 billion already implies increased orders flowing to its component suppliers.
Building a leading-edge fab from scratch is extremely hard. Rapidus faces real execution risk. Regardless of Rapidus's execution, ASML gets paid — the machines ship and revenues are locked in before a single production wafer is printed.
That guaranteed demand creates a second-order effect most investors overlook.
Whether Rapidus ultimately succeeds or stumbles, ASML gets paid either way — the machines ship regardless.
Fourth domino: The bottleneck inside the bottleneck — Zeiss and the supply chain that can't be replicated
The most critical supplier is Carl Zeiss SMT, the German optics division that manufactures the multilayer mirrors inside every EUV machine. These mirrors must be polished to sub-nanometer precision — if the mirror surface were scaled to the size of Germany, the largest bump would be less than a millimeter tall. No other company on Earth can produce them at this specification. Zeiss's EUV optics division is, in effect, the bottleneck inside the bottleneck.
When ASML ramps production, Zeiss and other precision suppliers ramp with it. ASML's 2026 guidance of €34–39 billion implies a meaningful increase in orders flowing downstream.
This is why ASML earnings matter beyond ASML itself. Tuesday's guidance will set the demand outlook for a whole ecosystem of European and Japanese precision-manufacturing companies. And Zeiss's optics capacity may be what decides how fast ASML can deliver.
But there's a geopolitical layer here that adds both opportunity and risk.
Fifth domino: The geopolitical weapon — export controls turn ASML into a policy tool
ASML is headquartered in the Netherlands, giving the Dutch government and the EU direct influence over who can access leading-edge lithography. Export controls on advanced semiconductor equipment can restrict which countries build leading-edge fabs.
This is why the Rapidus subsidy story matters beyond Japan. Nations are racing to secure access to ASML's machines because they understand that without EUV, you cannot produce the most advanced chips. Full stop.
China hasn't cracked EUV, and there's no credible timeline for when it does — which means ASML's export-control exposure is a risk ceiling, not a floor. For now, export controls actually help ASML. Allied nations are rushing to place orders because they fear losing access to the technology later.
The geopolitical premium built into ASML's stock is real, and it's growing.
Historical parallel: TSMC's own monopoly formation — and what it teaches about physics-based moats
The most instructive parallel for ASML isn't Intel's x86 dominance — it's TSMC's own monopoly formation in the 1990s and 2000s. TSMC didn't invent the transistor or design the best chips. It simply became the only company that could make them at the leading edge. After that, the cost of copying its capabilities grew faster than any rival could spend.
ASML's moat follows the same pattern but is arguably deeper. TSMC's edge is baked into its structure — decades of manufacturing know-how, customer ties, and yield improvements. ASML's advantage is rooted in physics. EUV lithography requires generating light at a 13.5-nanometer wavelength by firing a laser at molten tin droplets, then focusing that light through mirrors polished to atomic-level precision. The entire system operates in a near-perfect vacuum. No startup, no sovereign wealth fund, and no state-backed lab has demonstrated a credible alternative approach.
Architectural moats erode when paradigms shift — Intel's x86 dominance cracked when mobile chips moved to ARM. Physics-based moats erode only when someone invents new physics. ASML's monopoly is likely more durable than Intel's was, because there is no known alternative lithography approach close to production-ready. The risk isn't competition — it's that demand for leading-edge chips could plateau. But with AI training runs doubling in compute requirements roughly every six months, that plateau isn't visible yet.
What could go wrong
Risk 1: The stock is priced for perfection. ASML is up roughly 12% in a single week through mid-April, heading into results. A trailing P/E of ~51 means any miss on guidance — even a cautious tone on 2027 — could trigger a sharp pullback. With a beta of 1.38, ASML amplifies market moves in both directions.
Risk 2: Export controls tighten further. The specific trigger to watch: if the Dutch government extends its export license framework to cover DUV (deep ultraviolet) systems below 28nm before Q3 2026, ASML's addressable market in non-allied geographies contracts meaningfully. The Netherlands has already restricted some shipments; each incremental restriction shrinks the customer base.
Risk 3: AI spending cycle decelerates. The invalidation signal here is hyperscaler capex guidance. If Microsoft or Google forecast data center spending growth below 20% year-over-year on their next earnings calls, the fab-buildout plans baked into ASML's €34–39 billion 2026 guidance start to look shaky. ASML's order book has long lead times, but cancellations can and do happen.
Risk 4: A Chinese EUV breakthrough. We estimate an 85–90% probability the monopoly thesis remains intact over two years. The 10–15% tail risk — a Chinese EUV breakthrough — would be severe, collapsing ASML's pricing power overnight. No credible evidence suggests this is imminent, but the sheer strategic incentive means China is spending aggressively to try.
Watchlist
| Ticker | Level | Status | Why |
|---|---|---|---|
| ASML | Trailing P/E ~51; beta 1.38 | holding | The monopoly supplier itself. Earnings Tuesday will set the tone for the entire chip equipment sector. The 52-week low was around $614 — the stock has more than doubled from its trough, reflecting the monopoly premium and AI demand acceleration. |
| TSM | Near all-time highs as of mid-April 2025 | approaching | ASML's biggest customer. Reports Wednesday. Strong March sales already confirmed. Watch capex guidance — it has historically led ASML's order intake by one quarter. Back-to-back results with ASML create a rare two-day demand signal. |
| BESI | Watch for ASML guidance read-through | watching | Dutch chip assembly equipment maker that benefits from the same fab expansion cycle ASML drives, but operates in a different segment (packaging and die-attach rather than lithography). Not a direct ASML component supplier, but a derivative play on the same capacity buildout. |
| AMAT | Watch for packaging-tool order commentary | watching | Applied Materials is the largest U.S. chip equipment maker. Doesn't compete with ASML on EUV but its etch and deposition tools are pulled by the same CoWoS and HBM advanced-packaging buildout that drives ASML demand. Watch AMAT's packaging-tool order commentary as a cross-check on the AI fab cycle. |
| INTC | Watch for fab investment signals | watching | Intel is an ASML customer trying to catch up on leading-edge manufacturing. ASML's guidance will hint at how aggressively Intel is ordering new tools. |
