ASML Takes a 4.86% Hit from the MATCH Act as the SOXX Flashes Overbought Warnings

A single word — "serviced" — in a draft US bill that hasn’t even passed a vote cost Europe’s most valuable tech stock nearly 5% in a single session. The ASML share price slid 4.86% to €1,264 in Amsterdam on 12 May, far outpacing a 1.2% dip in the broader technology sector. The trigger: the bipartisan MATCH Act, which would extend American export controls to cover not just new sales of DUV lithography systems to Chinese firms such as SMIC, Huawei, CXMT and YMTC, but also the maintenance of machines already on their factory floors.

That servicing ban cuts to the heart of ASML’s recurring revenue model. Service contracts and upgrades on the installed base provide a steady, high-margin income stream that is far less lumpy than new equipment sales. If the MATCH Act becomes law, that recurring cash flow would be at risk. The bill includes a 150-day window for allies like the Netherlands and Japan to align their own export rules, giving investors a concrete timeline for lobbying and licensing negotiations.

The selloff came even as the semiconductor sector broadly extended a dizzying rally. The SOXX index had surged 74% in just six weeks, sending the Relative Strength Index above 90 — a level that normally signals extreme overbought conditions. Analysts have warned of a potential correction of up to 25% if the AI investment cycle cools. ASML itself trades at a forward P/E of roughly 42, valuing the company at about €502 billion, making it vulnerable to any shift in sentiment.

Should investors sell immediately? Or is it worth buying Asml?

Operationally, the picture is more mixed. ASML’s China revenue share has already been declining: 19% of system sales in the first quarter of 2026, down from 36% in the final quarter of 2025. Management had guided for around 20% for the full year 2026, but that forecast did not account for the MATCH Act. A downgrade from Buy to Hold by an investment bank in early May added to the selling pressure, alongside news that key customer TSMC plans to delay deployment of ASML’s high-margin High-NA EUV machines until at least 2029.

Yet ASML still holds an order backlog of roughly €38.8 billion at the end of 2025 and has raised its 2026 revenue forecast to €36–40 billion. AI-driven demand from TSMC, Samsung and SK Hynix is filling the gap left by China. SK Hynix recently placed an order worth $8 billion for new EUV tools, and TSMC confirmed $50 billion in AI-chip investments. Institutional investors have taken note: Mitsubishi UFJ Asset Management added to its ASML position in double-digit percentages last month.

Diplomatic channels remain active. China has cleared the way for a visit by the Dutch trade minister to Beijing before the summer — a sign that both sides are willing to talk. Meanwhile, top executives from Apple, Tesla and Qualcomm are negotiating in Beijing ahead of a summit between President Trump and President Xi Jinping. How far these talks go in softening Washington’s stance may determine whether ASML’s premium valuation holds or becomes the next target for sellers.
