ASML Gains From AI-Led Demand Surge for HBM and DRAM Nodes

Sustained demand for artificial intelligence and high performance computing chips by global data centers, AI labs and hyperscalers has reinforced ASML’s long-term growth outlook as the company provides extreme ultraviolet (EUV) semiconductor lithography tools to chip manufacturers that enable them to accelerate capacity expansion.

ASML’s management on the fourth-quarter 2025 earnings call noted that ASML’s customers have become more confident about medium-term AI demand, leading to stronger order intake and investment plans as chipmakers transition from 4-nanometer to 3-nanometer and prepare for the 2-nanometer transition.

As EUV intensity per wafer continues to rise, AI and HPC workloads are addressed more efficiently. In memory, robust demand for high-bandwidth memory (HBM) and advanced DRAM nodes is expected to tighten supply through at least 2026, further supporting EUV demand.

ASML is also benefiting from a growing installed base, which is driving high-margin service and upgrade revenues as customers increasingly view upgrades as the fastest way to add capacity. With a €38.8 billion backlog and reaffirmed long-term targets, ASML remains well-positioned to capitalize on the AI-led semiconductor investment cycle.

For 2026, ASML expects its revenues in the range of €34-€39 billion. The Zacks Consensus Estimate for ASML’s 2026 revenues is pegged at $43.31 billion, indicating a year-over-year improvement of 17%.

ASML Dominates the EUV Landscape Unchallenged

Although ASML faces competitive pressure from players like Lam Research, Applied Materials and KLA Corporation in the broader wafer equipment manufacturing market, ASML holds a near-monopoly in EUV technology.

EUV is crucial for the world’s most advanced chips at 3nm and below; it benefits from extraordinary pricing power and strategic importance with major customers like TSMC, Samsung and Intel.

ASML’s venture into sub-2nm production with High Numerical Aperture (High-NA) EUV systems is the next technological leap for chipmakers. This technology will provide ASML with long-term potential as the industry moves toward denser and more efficient chips. ASML’s High-NA machines will be central to that shift.

The Zacks Consensus Estimate for ASML’s 2026 earnings is pegged at $33.63, indicating a year-over-year improvement of 20.3%. The consensus estimate has been revised upward in the past seven days.
