ASML is a Dutch technology company founded in 1984 as a joint venture between Philips and ASM International. In simple terms: ASML builds the machines that build microchips. Every time TSMC, Samsung, or Intel manufactures a processor — for your smartphone, a data-center AI server, or a car — they use equipment made by ASML to “print” the circuit patterns onto silicon wafers with extraordinary precision.

Lithography is the step in chipmaking where a light source is used to expose a pattern onto a photosensitive layer on a wafer — essentially like a very high-precision photocopier for circuits. ASML’s most advanced systems use Extreme Ultraviolet (EUV) light with a wavelength of just 13.5 nanometers (a human hair is ~80,000nm wide) to print features smaller than any competing technology can achieve.

Each EUV machine is a school-bus-sized engineering marvel: it fires laser pulses at tin droplets to create plasma that emits the EUV light, then bounces that light off ultra-precise mirrors machined to within a fraction of an atom’s width. A single machine contains around 100,000 individual parts and takes two years to manufacture. ASML designs, assembles, and services these systems from its base in Veldhoven, Netherlands.

ASML generates revenue through two main pillars:

Why does this model matter for investors? System sales are lumpy (customers order in large batches), but IBM revenue is sticky and growing. As ASML’s installed fleet expands — now thousands of machines across fabs worldwide — the annuity-like service business becomes a larger and more predictable portion of total revenue. This is similar to the classic “sell razors, profit from blades” model, scaled to multi-billion-euro machines.

Geographic Revenue Mix (FY2025 estimates)

ASML operates at the intersection of multiple powerful secular trends that are reshaping the global technology landscape:

1. The AI Infrastructure Buildout. Every AI model trained or run requires semiconductors — GPUs, HBM memory, custom ASICs. TSMC, Samsung, and Intel are all racing to expand capacity at the leading edge (3nm, 2nm, and beyond), and every leading-edge chip requires multiple passes through an EUV machine. ASML’s CEO noted in January 2026 that customers shared “a notably more positive assessment of the medium-term market situation, primarily based on more robust expectations of the sustainability of AI-related demand.”

2. The High-NA EUV Ramp. ASML’s newest generation — the High-NA EUV (TWINSCAN EXE series, 0.55 NA) — enables features as small as 8nm in a single exposure, 2.9× denser than Low-NA can achieve. Intel and Samsung have taken early units. High-NA machines cost over €350 million each. As chipmakers transition from 2nm to 1.4nm nodes, High-NA becomes essential, representing a major multi-year revenue catalyst.

3. Memory Cycle Recovery. DRAM and NAND markets are recovering from a 2022–2023 downturn. High-Bandwidth Memory (HBM) — the stacked DRAM that feeds AI accelerators — is booming and requires advanced lithography tools. ASML guided that EUV revenues will increase significantly in 2026 as a result of dynamics in advanced Logic and DRAM.

4. CHIPS Act & Geopolitical Fab Diversification. The US, EU, Japan, and India are all subsidizing semiconductor manufacturing domestically. Intel’s Ohio and Arizona fabs, TSMC’s Arizona gigafab, and Samsung’s Texas fab all require ASML equipment, expanding geographic customer diversity and creating long-term structural demand outside of Taiwan and Korea.

ASML’s competitive picture depends on which product line you’re examining. In EUV lithography, ASML has no competitor. In DUV and the broader semiconductor equipment market, it faces meaningful but narrow rivals.

Annual Snapshot

Balance sheet highlights (Q1 2026 per SEC filing): Total assets €48.1B; shareholders’ equity €20.8B; debt/equity ratio ~0.24 — a conservatively levered balance sheet. The company returned capital via a €7.50/share dividend for 2025 (up 17% vs 2024) and announced a €12 billion share buyback program through 2028. Cash & equivalents stood at ~€8.4B at end of Q1 2026.

Valuation is arguably the most contested aspect of ASML’s investment case in mid-2026. The stock has surged approximately 148% from its 52-week low, raising legitimate questions about how much of the fundamental story is already priced in.

Near-term (2026–2027):

EUV system shipments are accelerating — ASML guided for at least 60 EUV systems in 2026 (vs 48 in 2025), rising to at least 80 per year by 2027. Q4 2025 net bookings hit a record €13.2 billion, of which €7.4 billion was EUV-specific. Q1 2026 results beat consensus: €8.8B in sales at 53% gross margin, prompting a full-year guidance raise to €36–40B.

Medium-term (2027–2030):

The High-NA EUV ramp is the single most important catalyst. Each EXE:5200B unit priced at >€350 million vs ~€180 million for a standard NXE scanner means the transition to High-NA will expand average selling prices significantly. High-NA units are projected to represent roughly one-quarter of EUV revenue by 2028, according to Counterpoint Research (February 2026). Simultaneously, the DRAM/HBM memory cycle adds a second structural growth leg beyond logic-only demand.

Long-term (2030 and beyond):

ASML is in early feasibility studies for Hyper-NA EUV — the generation beyond High-NA — targeting the 2030s. IBM/service revenue will continue compounding as the installed fleet grows. CHIPS Act-driven fab construction in the US and Europe adds new customers in new geographies. Semiconductor content per vehicle (automotive), per data center, and per consumer device continues to expand.
