So here's the thing about making the world's most advanced chips: you need some pretty fancy equipment. And when it comes to the fanciest equipment of all—the extreme ultraviolet (EUV) lithography machines that etch impossibly tiny circuits onto silicon—there's really only one game in town: ASML Holding N.V. (ASML). And they just made their game a whole lot harder for anyone else to play.
ASML's researchers have pulled off a breakthrough that sounds like something out of a sci-fi novel: they've figured out how to significantly crank up the power of a critical light source inside their EUV machines. Why does that matter? More power means these incredibly complex machines can work faster. A lot faster.
According to reports, this advancement could lift chip output by as much as 50% by the end of the decade. That's not just an incremental improvement; that's a leap that could further cement ASML's dominance over the handful of U.S. and Chinese startups trying to build alternatives.
Think about the customers here: Taiwan Semiconductor Manufacturing Co. Ltd. (TSM) and Intel Corp. (INTC) rely on these machines to produce the advanced semiconductors that power everything from your smartphone to the AI models everyone's talking about. ASML is essentially the company that sells the shovels in the AI gold rush, and they just invented a better, faster shovel.
In the U.S., startups like Substrate and xLight have attracted hundreds of millions in funding (with xLight even getting a nod from the Trump administration) to try and build a domestic alternative. China, blocked from buying these machines due to export controls, is also racing to develop its own. But ASML isn't standing still. They're targeting what many consider the most technically demanding part of the whole system: generating light with enough consistent power for high-volume production.
Michael Purvis, ASML's lead technologist for the EUV light source, said the system can now consistently produce 1,000 watts under the same conditions customers require. Even more impressive, Purvis said the company sees a "clear path" to 1,500 watts and "no fundamental barrier" to reaching 2,000 watts in the future.
Teun van Gogh, executive vice president for ASML's NXE EUV line, translated that power into practical terms: customers could be processing about 330 wafers per hour by 2030, up from about 220 today. That's the kind of productivity jump that keeps foundries coming back for more.
This technological push comes as ASML is riding an incredible wave of demand, largely thanks to the AI boom. The company just capped off 2025 with what can only be described as blockbuster results.
Full-year net sales hit $39.16 billion, with net income of $11.5 billion. The fourth quarter alone brought in $11.62 billion in revenue, partly from the recognition of two of their newest, most advanced "High NA" EUV systems. Net bookings in Q4 were a staggering $16.77 billion, with more than half tied to EUV systems.
Perhaps the most telling number is the backlog: ASML ended the year with approximately $46.47 billion worth of orders waiting to be filled. That's a record, and it reflects the sustained, massive investment from semiconductor customers betting big on AI and advanced chip production.
CEO Christophe Fouquet put it simply, saying customers have "expressed greater confidence in the medium-term outlook, mainly due to stronger expectations for durable AI-driven demand." In other words, the AI build-out isn't a flash in the pan; it's a long-term shift, and ASML is sitting right at the center of it.
Looking ahead to 2026, ASML expects the party to continue. They're forecasting net sales between $40.72 billion and $46.7 billion. And in a move that screams confidence, the company's board authorized a new share repurchase program of up to $14.37 billion through 2028. When a company plans to buy back that much of its own stock, it's basically saying, "We think our future is very bright, and we want our shareholders to benefit directly."
The market seems to agree. ASML stock gained 101% over the last 12 months, absolutely crushing the PHLX Semiconductor Index's already-strong 64% return. Year-to-date, ASML is up 38%, compared to the index's 16%. The stock was trading near its 52-week high of $1,493.47.
So, to sum it up: ASML has a technological moat that just got wider, a financial performance that's through the roof, a backlog that guarantees work for years, and a management team so confident they're planning to send billions back to shareholders. For any would-be rival looking at the EUV market, the message is clear: catching up just got a whole lot harder.
