ASML Q1 2026 Results Confirm AI-Driven Upswing, But High Valuation Limits Upside

What happened

ASML reported impressive Q1 2026 results, driven by surging demand for lithography machines amid hyperscaler-led AI chip investments. The company raised its full-year 2026 revenue outlook to €36-40 billion, up from €34-39 billion, and posted a gross margin of 53% and operating margin of 36%, its highest in a year. This performance aligns with the DeepValue master report's base and bull scenarios, which anticipated strong AI-driven orders and operational leverage. However, the stock already trades at 48.1x trailing P/E and 38.2x EV/EBITDA, embedding tight execution on the EUV shipment plan of 60 low-NA tools in 2026. The key risk remains geopolitical exposure to China and the potential for export controls to expand into servicing and licensing.

Implication

Investors should note that while ASML's Q1 2026 results and raised outlook support the bullish case, the stock already prices in these improvements at $1,457.7 with a P/E of 48.1x. The master report's WAIT rating and attractive entry of $1,250 imply that near-term upside is limited unless execution on the 60 EUV shipment target and margin guidance (51-52% in Q2) proves flawless. The raised revenue outlook reduces downside risk from demand softening, but geopolitical risks around China (approximately 20% of sales) remain a key swing factor. Free cash flow was negative in Q1 (-€2.6B), highlighting working capital volatility that could pressure valuation if shipment delays occur. Therefore, while the company's fundamentals are strong, the risk/reward is balanced, and we recommend waiting for a better entry point or concrete evidence of shipment and margin stability.

Thesis delta

Q1 2026 results and raised guidance strengthen the bull case, reducing near-term execution risk, but the stock's price already reflects this optimism. The WAIT rating remains appropriate as valuation at 48x P/E leaves no room for error, and geopolitical risks persist. The key shift is that AI demand visibility has improved, but the margin of safety is still inadequate for a buy at current levels.
