Should Investors Buy ASML as AI Growth Meets a Premium Valuation?

Read MoreHide Full Article

Key Takeaways

  • ASML raised 2026 sales guidance to 43-45 billion euros as AI demand lifts Logic, Memory and EUV revenue.
  • ASML is close to securing all EUV orders needed for 2027 and has already received many orders for 2028.
  • ASML trades at 31.5X forward earnings, while export controls and capacity expansion add execution risks.

ASML Holding NV (ASML - Free Report) is benefiting from accelerating AI-related spending across advanced Logic and Memory manufacturing. Demand is broadening across lithography and service revenues, giving the company better visibility into 2027 and 2028.

That momentum comes with a demanding valuation. Investors weighing ASML must balance faster growth, cash conversion and deeper orders against export-control uncertainty, capacity-ramp execution and a stock priced near its five-year median forward multiple.

ASML's AI Demand Powers a Bigger 2026 Outlook

Management expects advanced foundry Logic revenue to increase about 25% in 2026, Memory revenue to rise 75% and extreme ultraviolet (EUV) revenue to grow about 45%. ASML also raised 2026 net sales guidance to €43-€45 billion and gross margin guidance to 54-56%.

Applied Materials, Inc. (AMAT - Free Report) is one of the stocks in ASML's wafer-fabrication equipment peer group, providing an industry comparison point as investors assess the AI spending cycle. Lam Research Corporation (LRCX - Free Report) is another peer in that group, offering a second reference for semiconductor equipment exposure.

ASML Orders Extend Visibility Through 2028

Customer commitments now reach beyond the next year. By the second quarter, ASML was close to receiving all EUV orders needed for 2027 and had already received many for 2028, reducing reliance on near-term bookings.

ASML plans to increase 2027 low numerical aperture EUV capacity about 30% from roughly 65 systems in 2026. Deep ultraviolet immersion capacity is following the same 30% expansion path from about 130 systems, while another increase is being evaluated for 2028.

ASML's Cash Generation Strengthens Funding Flexibility

Capital efficiency has improved. Trailing 12-month return on invested capital is 39.1%, above ASML's 10-year median of 26.2%, while cash flow conversion of 104.6% and free cash flow conversion of 91.3% stand well above company medians.

Second-quarter operating cash flow reached €1.70 billion and free cash flow was €1.32 billion. ASML also repurchased about €1.1 billion of shares, adding flexibility to fund expansion while continuing shareholder returns.

ASML's Valuation Leaves Little Room for Error

ASML trades at 31.5X forward 12-month earnings versus 23.7X for its industry, 20.7X for the sector and 20.0X for the S&P 500. The premium means investors are already paying for substantial execution.

The multiple is close to ASML's five-year median of 31.6X, so the stock is not unusually expensive relative to its own history. Still, its premium to broader benchmarks leaves less room for earnings or execution to disappoint.

ASML Faces Policy and Scaling Risks

China remains a material policy risk. Management expected the region to represent roughly 20% of total net sales, keeping export controls relevant because restrictions can affect which systems and services ASML may supply.

The capacity ramp adds execution risk. Manufacturing capacity, suppliers and trained employees must scale together, while broader High-NA EUV adoption still depends on customer qualification and insertion decisions. Those variables matter as ASML builds for commitments extending into 2028.

ASML's Mixed Signals Favor Selectivity

ASML's growth setup is favorable, but the premium valuation and execution dependencies argue for selectivity rather than an aggressive entry. Better demand visibility and cash generation strengthen the fundamental case, yet the margin for disappointment remains narrow.

ASML currently carries a Zacks Rank #3 (Hold) with a VGM Score of B, Growth Score of A, Momentum Score of A and Value Score of F. The Rank reflects a Hold setup for the next one to three months, while the scores favor growth and momentum but flag valuation. That mix keeps the near-term case balanced.
