ASML Raises 2026 Guidance on AI-Driven Demand, but Valuation Leaves No Margin of Safety

What happened

ASML reported Q2 2026 net sales of €9.3 billion and a 54% gross margin, beating guidance largely due to higher Installed Base Management revenue. Management raised Q3 sales guidance to €11–12 billion and full-year 2026 sales guidance to €43–45 billion, citing accelerating demand from AI-related advanced logic and memory customers. The company also reaffirmed plans to expand 2027 low-NA EUV and DUV immersion capacity by 30%, with low-NA EUV capacity already nearly fully booked. However, the stock trades at approximately 59x P/E and 47x EV/EBITDA, already discounting flawless capacity expansion, on-time shipments, and manageable China export restrictions. Popular coverage now shifts from demand confirmation to supply execution, questioning whether ASML can physically deliver enough tools without becoming the bottleneck.

Implication

Investors should treat this as a confirmation of demand, not a catalyst for further upside, because the market has already priced in near-perfect execution. The key near-term checkpoints are Q3 2026 guidance remaining at or above €11–12 billion, the 2027 capacity expansion plans being repeated without cuts, and customer capex commitments from TSMC and Micron staying firm. Any slippage in backlog conversion, supplier constraints, or a sharper-than-expected China revenue decline would likely de-rate the multiple. A better entry opportunity may emerge if the stock pulls back toward the $1,550–$1,600 range, where risk/reward improves. Until then, maintain a WAIT stance and monitor execution signals rather than chasing the guidance raise.

Thesis delta

The prior thesis was a WAIT rating based on premium valuation and execution risk despite strong demand. This news reinforces the demand strength with a guidance raise and capacity expansion plans, but it also raises the bar for flawless execution. No rating change is warranted; the stock remains a hold until evidence of on-time 2027 capacity conversion or a more attractive entry price emerges.
