Micron’s AI Boom Lifts ASML, but the MATCH Act Looms Large Over China Exposure
25.06.2026 - 17:24:13 | boerse-global.de
The Dutch lithography giant ASML is caught in a tug-of-war between surging AI?driven demand and escalating geopolitical uncertainty. Shares climbed 3.36% on Thursday to €1,600.40, powered by a blockbuster quarterly report from US memory maker Micron Technology, which beat expectations and reignited enthusiasm across the semiconductor complex. Since the start of the year, ASML’s stock has gained nearly 62%. Yet the current price remains about 6.4% below the 52?week high of €1,710 set just days ago — a reflection that for all the bullish momentum, a dark cloud still hangs over the company’s biggest single market.
The China Conundrum
China accounted for roughly one?third of ASML’s revenue in 2025. That share is expected to fall to around 20% in 2026 as new export restrictions bite. The company’s full?year revenue target of €36?billion to €40?billion rests on the assumption that demand from other regions — especially from high?bandwidth memory (HBM) and advanced logic — will fill the gap. In the first quarter of 2026, China’s contribution to net system sales already dropped to 19%, down from 36% in the final three months of 2025. For context, China poured €10.2?billion into ASML’s coffers in 2024, representing 36% of total revenue of €28.3?billion.
The near?term risk crystallizes in the so?called MATCH Act, currently being debated in the US Congress. The legislation would empower Washington to restrict Chinese access not only to extreme ultraviolet (EUV) machines — already banned for China — but also to deep ultraviolet (DUV) immersion systems, which have so far been subject only to partial limitations. A full DUV ban would sever a still?active revenue stream before the non?China order book can fully compensate. The Netherlands is pushing back: trade minister Sjoerd Sjoerdsma travelled to Washington to meet US commerce secretary Howard Lutnick and other lawmakers, but no final vote has been taken.
AI Demand: The Symmetrical Tailwind
Micron’s results provided the most concrete counterweight to those concerns. The company reported that its entire HBM production for 2026 is already sold out. High?bandwidth memory — the specialised DRAM that powers Nvidia’s H100 and other AI accelerators — relies on the most advanced lithography tools, exactly the machines ASML dominates. The world’s top memory makers are racing to expand capacity, and market observers now expect ASML to ship more than 80 EUV systems in 2027, up from 44 in 2025. For 2026, management has guided for at least 60 low?NA EUV units.
Should investors sell immediately? Or is it worth buying Asml?
The order book is already reflecting this strength. CEO Christophe Fouquet highlighted robust customer orders tied to AI?infrastructure build?outs. In the first quarter of 2026, net system sales reached €6.3?billion, of which EUV alone contributed more than €4.1?billion — including revenue from two High?NA systems. The annual guidance was recently revised upward, with revenue of €36?billion to €40?billion and gross margins between 51% and 53%. Key drivers include stronger demand for immersion systems and additional EUV potential outside China.
Beyond the immediate AI boom, ASML is also investing in future technologies. A recently announced partnership with Dutch research organisation TNO aims to expand Europe’s capacity for photonic?chip production in Eindhoven. While not a near?term catalyst, it underscores the company’s long?term commitment to maintaining its technological moat.
The Bear Case: Extraterritorial Reach and Valuation Risk
The MATCH Act is not a theoretical threat. The proposed law would give Washington the right to dictate what partner countries can sell to China’s chip industry, and it includes a clause that could even prohibit servicing already?delivered machines in China. If the US fails to reach agreement with allies, it could impose export restrictions on those allies themselves. The market’s sensitivity to the issue was laid bare after ASML’s Q1 earnings: despite the beat, the stock fell about 6% in after?hours trading solely on China?related commentary.
Management itself expects Chinese revenue to decline significantly in 2026 relative to the previous two years. The exact shape of the drop will depend on whether the MATCH Act passes in its strictest form. Meanwhile, the stock’s valuation leaves little room for disappointment. At current levels, shares trade roughly 42% above their 200?day moving average of €1,125 — a premium that could vanish quickly if negative headlines accumulate. The 50?day moving average of €1,386, about 12% below Thursday’s close, offers first technical support in a more adverse scenario.

What to Watch Next
The near?term direction of ASML shares hinges on two variables. First, how quickly Micron, SK Hynix and Samsung ramp capacity and place concrete EUV orders. Second, the fate of the MATCH Act. Diplomacy is still active: Minister Sjoerdsma is scheduled to lead a trade delegation to China in early July, with ASML representatives reportedly joining. The next major catalyst is the second?quarter earnings report, due in July. Whether management confirms, tightens or expands the 2026 guidance — and what it signals about DUV exposure to China — will shape the narrative for the second half of the year.
Technically, the relative strength index of 53 suggests neither overbought nor oversold conditions. The market is waiting for clarity. For now, ASML sits at the intersection of an AI?fueled demand supercycle and a geopolitical quagmire — and the next chapter belongs to Washington and the memory?chip makers.
