ASML stock tests rich valuation as China export risks intensify

ASML Holding ↘ 2.24% delivered a strong second quarter, reporting net sales of €9.3 billion with a 54% gross margin and net income of €2.9 billion, beating analyst expectations across the board. The Dutch chipmaking equipment giant raised its full-year 2026 revenue guidance for the second time this year, now projecting net sales of €43 billion to €45 billion, a sharp increase from the prior range of €36 billion to €40 billion.asml+2

AI Demand Drives Record Guidance

The results, reported on July 15, were fueled by sustained demand for advanced lithography tools tied to the AI infrastructure buildout. ASML guided third-quarter revenue to a range of €11 billion to €12 billion, with the midpoint representing a roughly 23% sequential increase over Q2. The company also raised its gross margin outlook for the full year to 54% to 56%, up from 51% to 53%.ad-hoc-news+2

Management confirmed plans to expand extreme ultraviolet lithography tool capacity by 30% for 2027, with a potential further expansion under evaluation for 2028. Each EUV system carries a price tag in the hundreds of millions of euros, making even incremental capacity additions worth billions in potential revenue.ad-hoc-news

According to Quartz, this marks the second time in 2026 that ASML has lifted its annual guidance, after an initial raise in April when it reported better-than-expected first-quarter results.qz+1

Valuation and Risk Cloud the Picture

Despite the strong fundamentals, ASML's stock has drawn scrutiny over its valuation. The shares were trading near $1,735 in late August, more than 38% above one widely cited fair value estimate. The stock carries a price-to-earnings ratio of roughly 53.7x, above both the semiconductor peer average and the broader industry.simplywall+1

Geopolitical risks remain a key concern. Reports in late August indicated that U.S. policymakers may be considering a near-total ban on ASML's deep ultraviolet lithography sales and servicing into China, which would go beyond existing restrictions on EUV shipments. China has historically accounted for around 20% of ASML's annual sales, and any escalation in export controls could affect both new tool revenue and the company's profitable installed base service stream.ad-hoc-news+1

Outlook Hinges on Sustained AI Spending

The bull case for ASML rests on its monopoly position in EUV lithography and the multi-year capital expenditure cycle driven by AI data centers. Nvidia ↘ 4.58% reported $96.2 billion in quarterly revenue in its latest results and guided for $108 billion in Q3, underscoring the downstream demand that ultimately feeds back to ASML's order book.ad-hoc-news

The bear case centers on whether the current premium is sustainable if tariffs weaken electronics demand or if China accelerates domestic lithography alternatives. ASML's next quarterly update will be closely watched for signals on how memory and logic customers are phasing their orders for EUV and High NA tools heading into 2027.
