Guidance Up Again: Why ASML Is the AI Trade Everyone Forgets About

ASML just raised its 2026 revenue guidance…again!

If you want to know whether the AI boom is real money or just a good story, don’t listen to the chip designers talking their own book. Watch the one company that sells the machines everybody needs, has no serious competition, and has to book orders years in advance. That company is ASML (AMS: ASML), and on 15 July it did something that should make even the AI sceptics sit up: it raised its full-year guidance again.

Beat, Raise, Repeat

Let’s start with the scoreboard. In the second quarter of 2026, ASML booked EUR9.3bn in total net sales, a gross margin of 54% and net income of EUR2.9bn. Both the top line and the margin came in above the company’s own guidance, driven largely by stronger-than-expected Installed Base Management sales, i.e. the servicing and upgrades ASML earns on the thousands of machines already humming away in customer fabs. Earnings per share landed at EUR7.59, up from EUR7.15 in the first quarter, and operating margin pushed up to a very healthy 37.1%.

The real headline, though, is the guidance. Back in April, ASML was steering the market towards 2026 revenue of EUR36–40bn. It has now lifted that to EUR43–45bn, with gross margin of 54–56%. For the current quarter, management is guiding to EUR11–12bn, so a big step up. When a company with ASML’s visibility raises its own forecast by roughly EUR6bn in a single quarter, that’s not a rounding error. That’s the sound of order books filling faster than the finance team can type.

The AI Narrative, But With Receipts

Everyone and their dog has an opinion on AI. What makes ASML interesting is that it turns the hype into hard numbers. CEO Christophe Fouquet put it plainly: ongoing AI investment is driving demand for advanced Logic and Memory chips, and customers are accelerating their capacity expansion plans. That’s showing up as commitments across ASML’s entire product range, and order intake stayed “extremely strong” through the first half.

So where exactly is the growth coming from? Break down the EUR6.6bn of net system sales this quarter and the answer is refreshingly balanced. By end-use, it was almost a coin-flip: Logic at 51% and Memory at 49%. The Logic story is the one people know, i.e. the leading-edge processors and accelerators powering AI data centres. But Memory is the quiet twin: all those GPUs are useless without mountains of high-bandwidth memory (HBM) sitting next to them, and that demand is now pulling ASML’s machines just as hard.

By technology, EUV lithography, ASML’s crown-jewel tech, and the stuff nobody else on Earth can make, accounted for 57% of system sales, up from a still-hefty share the prior quarter. The workhorse DUV immersion (ArFi) tools chipped in 29%, with KrF, ArF dry and metrology filling out the rest. In plain English: the highest-value, highest-margin machines are doing the heavy lifting, and that’s exactly what you want to see.

Building More Machines to Build More Machines

Here’s the tell that ASML believes its own story. Management is planning to add 30% to its 2026 low-NA EUV capacity for 2027 and is investigating another 30% on top for 2028. It’s doing the same on DUV immersion, up 30% for 2027, potentially another 30% in 2028. You don’t spend years and billions expanding factory floor space unless your customers have already told you, in writing, that they’ll take the output.

The Next Five Years: High NA Steps Into the Light

Zoom out, and the next half-decade is where the ASML thesis gets really juicy. The company’s job is to keep shrinking transistors, and its newest weapon is High NA EUV, a next-generation machine that prints even finer features than today’s tools. Each one costs north of EUR350m and ships in more crates than your average apartment block.

Until recently, High NA was a science project with a price tag. This quarter it graduated. ASML confirmed that its High NA EUV process option has been qualified on select layers of Intel’s 18A node, its first use in a high-volume Logic product. That’s the milestone bulls have been waiting for; proof that the technology works at scale in a real fab, not just in a lab. Despite the fact that TSMC has pushed out adoption of High NA EUV, the industry marches towards the next decade of nodes, and High NA is set to move from novelty to necessity. Each machine sold carries an eye-watering price and margin. Layer that on top of a growing installed base throwing off recurring service revenue and you have a business that should compound nicely well into the 2030s.

Enter Elon, Stage Left: The Terafab Angle

And then there’s the wildcard. In March 2026, Elon Musk formally unveiled Terafab, a vertically integrated mega-fab in Austin, Texas, jointly pursued by Tesla, SpaceX and Intel, aiming to produce more than a terawatt of AI compute per year and up to 100–200 billion custom chips annually. The price tag has ballooned from an initial ~US$20–25bn to as much as US$119bn across all phases, and Intel is bringing its leading-edge 14A (1.4nm-class) process to the party. Here’s the punchline for shareholders: you cannot build a leading-edge fab, let alone the most ambitious one ever proposed, without ASML’s EUV and, eventually, High NA machines. Every terawatt of Musk’s compute dream runs straight through Veldhoven, The Netherlands. Whether Terafab hits its wildly optimistic targets is anyone’s guess, but even a fraction of it is another enormous order pipeline pointed at the one company that can supply it.

The Bottom Line

Raised guidance, a 54% gross margin, a 51/49 Logic-Memory split that spreads the risk, a High NA machine finally proving itself in Intel’s fab, and a Musk-sized moonshot that only ASML can equip. Add a growing dividend (EUR1.88 interim declared) and EUR1.1bn of buybacks in the quarter, and you have a monopoly compounding at scale. ASML isn’t cheap, and it never will be, but 2Q26 was another reminder of why the market keeps paying up for the one true toll-booth on the road to AI.
