Shares of ASML surged after the Dutch lithography giant delivered a Q2 that didn't just beat expectations — it forced management to tear up the full-year playbook for the second time in three months. The question now is whether the stock, already up roughly 66% year-to-date, has priced in a supercycle that still has room to surprise.

The Numbers Were Better Than Almost Anyone Expected

ASML posted Q2 net sales of €9.3 billion with a 54.0% gross margin and €2.9 billion in net income — topping the high end of its own guidance range of €8.4–9.0 billion at a 51–52% margin . Earnings per share of $8.32 beat the Street's $7.98 estimate . The main reason for the upside was the installed-base business — revenue from servicing and upgrading machines already in customers' factories — which came in at €2.8 billion, €300 million above expectations .

A €6 Billion Guidance Jump Tells You Where AI Spending Is Really Going

ASML raised its full-year 2026 revenue forecast to €43–45 billion, up sharply from the €36–40 billion range set just one quarter ago . That roughly €6 billion midpoint increase in a single quarter signals that the AI-driven capital spending cycle is not only intact but accelerating . EUV revenue jumped 45% year-over-year, while memory-related revenue surged 75% , fueled by demand for high-bandwidth memory chips essential to AI processors.

ASML Is Already Building for a Bigger Future — and Betting It Arrives

Management plans to add 30% to its 2026 EUV production capacity of roughly 65 systems for 2027, and an equivalent 30% increase to its older-generation immersion capacity of about 130 systems, with further 30% expansions under review for 2028 . CEO Christophe Fouquet said order intake was "extremely strong" as customers accelerated expansion plans .

The Risk Is Hiding in Plain Sight

ASML is already experiencing demand fluctuations for 2027 and 2028, requiring continuous capacity-planning adjustments . Export controls targeting China could create turbulence , and some customers are pushing back on the pricing of ASML's next-generation systems, finding them too expensive . For a stock trading at a market cap north of $600 billion, the margin for error is razor-thin: investors are no longer paying for today's beat but for a multi-year spending wave that must not slow down.
