ASML Rides Simultaneous Memory and Logic Boom to Fresh Highs as Supply Constraints Bite

ASML shares hit 52-week high as AI boom drives synchronized logic and memory chip demand. Major orders and mega-projects underscore structural growth, but overvaluation risks caution.

The lithography giant’s stock hit a new 52-week high of €1,691 on Wednesday, before settling at €1,675 — a gain of roughly 70% since the start of the year. The rally, which lifted the shares 152% from an August low of €593.60, reflects a structural shift in semiconductor investment that is proving unusually durable.

What sets this cycle apart is the synchronised surge in demand from both logic and memory chipmakers. Typically, capital expenditure in these two segments moves out of phase, but the artificial-intelligence boom is forcing them to ramp simultaneously. SK Hynix recently placed a multi-year order for extreme ultraviolet (EUV) lithography systems worth more than $7 billion, earmarked for expanding high-bandwidth memory (HBM) capacity — the specialised memory that powers AI accelerators. This memory leg is now running alongside the logic leg, creating a tailwind that ASML has rarely enjoyed.

The appetite for ASML’s tools extends beyond established chipmakers. The company is involved in the so-called Terafab project, a joint venture between Tesla, SpaceX and Elon Musk’s AI lab xAI, which envisions a $55 billion semiconductor plant in Austin, Texas, to produce chips for robotics, AI and space-based data centres. Chief executive Christophe Fouquet described the megaproject as a “test of ASML’s delivery capacity”, underscoring the tension between soaring demand and the company’s own supply-chain limits. Separately, Tata Electronics has signed a memorandum of understanding with ASML to build a semiconductor ecosystem and a new fab in India — the first such facility in the country. While India is not a near-term revenue driver, the deal signals that ASML’s geographic reach is still expanding.

The supply-demand imbalance is expected to persist. Fouquet has said he expects chip supply to lag demand for another two to five years, driven primarily by the global build-out of AI data centres. ASML is responding by ratcheting up production: it plans to deliver roughly 60 low-NA EUV systems in 2026, a 25% increase from 2025, and has set a capacity target of 80 units for 2027. The lead time for these machines — 12 to 24 months — is becoming the semiconductor industry’s critical bottleneck.

The dramatic share price rally has drawn caution from some corners. JPMorgan warned on Wednesday of potential “market tantrums” in the semiconductor sector, noting that chip stocks are overweight in global indices relative to their actual revenue contribution, raising the risk of sudden sell-offs. Technically, the stock is running hot: the relative strength index stands at 67.1 — just below the overbought threshold of 70 — and the price is roughly 23% above its 50-day moving average. Some analysts also flag that the price-to-earnings multiple is well above its historical median.

Yet ASML’s order visibility is unusually high for a capital-equipment maker. Customer commitments stretch across multiple years, dampening the earnings volatility that has historically plagued semiconductor cycles. For 2026, the company projects revenue of €36 billion to €40 billion, with a gross margin of 51% to 53%. By 2030, it targets €44 billion to €60 billion in sales, underpinned by high-NA EUV and a second growth leg from HBM memory.

The China risk that once haunted the thesis has largely faded. In the first quarter of 2026, China’s share of ASML’s system revenue fell to 19% — down from 36% in the prior quarter. The decline mostly hits lower-margin DUV systems; EUV tools have never been shipped to China. The export restrictions therefore target the least valuable part of the portfolio.

At a market capitalisation of €613 billion, ASML is no longer priced as a cyclical equipment maker. The market is assigning value to what the company has become: the inevitable gatekeeper for every advanced chip, AI or otherwise. And with the AI era only in its early innings, the tollbooth is just beginning to collect.
