ASML’s Two-Speed Engine: Memory Surge vs. Geopolitical Drag

ASML shares surge on memory capex boom but face legislative risks from US MATCH Act. Q2 results on July 15 will test 2026 guidance.

The Dutch lithography giant is caught between two powerful currents. One is a memory-chip investment cycle of historic proportions, with South Korean manufacturers alone pledging $520 billion in new capacity over several years. The other is a legislative threat from Washington that could slash a fast-growing revenue stream from China. The stock has already priced some of the optimism, but the real test comes on July 15, when ASML reports second-quarter results and investors will look for clues on whether the 2026 revenue guidance withstands the political headwind.

Shares closed Friday at €1,628.00, a gain of nearly 5% on the day, partially reversing a sharp sell-off earlier in the week. The rebound was part of a broader risk-on move after soft U.S. jobs data, but the stock remains 6.86% below its all-time high of €1,748.00 set on June 30. Since the start of the year, the equity has surged 64.73%, and over the trailing twelve months it has more than doubled, gaining 140.83%. That blistering run has pushed the price-to-earnings ratio to roughly 62.8, only a shade below the semiconductor sector average of 65.7 but well above a model-based fair value of 52.9, raising questions about how much future growth is already baked in.

The memory windfall is real

The bull case rests on a tangible catalyst: a capex boom in memory chips, the segment that now drives ASML’s order book. In the first quarter, memory accounted for 51% of new sales, up from 30% in the prior quarter. South Korea represented 45% of quarterly revenue, Taiwan another 23%. Micron, Samsung and SK Hynix have all announced massive expansion plans. Micron alone raised its fiscal-year capital expenditure to $27 billion from $25 billion in late June, propelling ASML shares 24.3% higher that month even without any company-specific news. The trio’s heavy reliance on extreme ultraviolet (EUV) lithography machines underscores ASML’s central role in the AI-driven capacity build-out.

ASML’s own guidance reflects that demand. In April, the company lifted its 2026 revenue forecast to a range of €36 billion to €40 billion, aided by long-term supply contracts that have prompted customers to accelerate their capacity plans. Chief financial officer Roger Dassen said the company expects to deliver about 60 low-NA EUV systems in 2026, a 25% increase from 2025, and as many as 80 in 2027. Analysts at BofA Securities remain bullish, pointing to rising immersion lithography demand and growing EUV capacity, and see potential for even higher earnings power through 2027.

The legislative shadow lengthens

Yet the same optimism is tempered by a legislative time bomb. The so-called MATCH Act, currently being debated in the U.S. Congress, could expand existing export restrictions on ASML’s deep ultraviolet (DUV) immersion systems and potentially sweep in the company’s lucrative service business in China. The Dutch government, meanwhile, formally joined the U.S.-led Pax Silica alliance on July 1, a move that makes tighter multilateral trade curbs more likely. Analysts are still unsure whether the bill would target all DUV systems or merely extend current limits on immersion tools, but the uncertainty alone is weighing on the stock.

ASML itself is already factoring in erosion. It expects China to account for roughly 20% of revenue this year, down from an estimated 33% in 2025, as export controls and demand normalization take hold. Should the MATCH Act pass in a broad form — covering services as well as new sales — the hit could be material. Analysts estimate a revenue drag in the low single digits and a potential 10% reduction in earnings per share. Jefferies warns that the market may have already priced in much of the good news, and that valuation multiples are likely to compress gradually, capping upside.

Technicals and the July 15 pivot

Chart watchers see a stock that is still technically sound but not immune to shocks. The relative strength index of 54.6 is neutral, and the shares trade comfortably above all major moving averages, including the 50-day line at €1,442.48 and the 200-day line at €1,148.68. Yet the annualized 30-day volatility of 62.82% means any fresh legislative development could produce sharp swings in either direction.

The next concrete catalyst is the July 15 earnings release. Investors will scrutinize whether management reaffirms the €36–€40 billion 2026 revenue range or signals a downward revision. The order intake for the second quarter will be equally important, given that customers in the logic and memory segments — notably TSMC — have delayed their transition to ASML’s new high-NA EUV machines, which cost between €350 million and €400 million each. A soft order figure or cautious guidance could push the stock back toward the 200-day moving average. Conversely, strong bookings and a steady outlook would bring the €1,748 record high back into striking distance.

As the largest second-weighted stock in the AEX index with a 14.69% weighting, ASML’s performance will also ripple through the broader Dutch market. For now, the memory boom and the legislative logjam are locked in a standoff, and July 15 will determine which force prevails.
