ASML sits at the center of the AI chip supply chain thanks to its exclusive extreme ultraviolet lithography machines, and a string of recent, large orders from major foundries has pushed its backlog and revenue outlook sharply higher. This piece looks at the monopoly economics behind ASML’s machines, the concrete orders from SK Hynix and Samsung that matter most, how those deals map into revenue and margins, and the key risks that could temper the upside.
At the core is a single technical fact: ASML supplies the only commercially viable EUV tools for patterning chips at 7 nanometers and below. That exclusivity creates a choke point — fabs cannot scale next-generation AI accelerators without access to these machines. Competitors like Nikon and Canon do not offer production-ready EUV systems, so demand funnels directly to ASML.
Major foundries and memory makers depend on those capabilities. Taiwan Semiconductor Manufacturing, Samsung, Intel, and SK Hynix all require EUV capacity to produce the logic and high-bandwidth memory dies that feed modern AI training clusters. As chip designers from Nvidia and AMD push performance, foundries must secure ASML slots to meet aggressive ramp schedules.

ASML holds a 100% market monopoly on extreme ultraviolet lithography systems required for sub-7nm AI chip production, with SK Hynix committing $8B for approximately 30 EUV systems by December 2027 and Samsung planning to secure 20 EUV systems for its Pyeongtaek P5 fab worth approximately $4B, collectively boosting backlog visibility into 2027 revenue.
The SK Hynix commitment is concrete and large: 11.95 trillion won, roughly $8 billion, for EUV tools with delivery by December 31, 2027. At typical EUV list prices in the $250 million to $300 million range per unit, that order likely corresponds to about 30 machines and equals a material share of a single year’s revenue for ASML. Deals of that size alter forward visibility because they are booked into backlog well before revenue is recognized.
Samsung’s move is similarly meaningful. Reports indicate Samsung intends to secure around 20 EUV systems for its Pyeongtaek P5 fab as construction resumes, with a target completion in mid-2028. Those 20 machines would add roughly $4 billion to ASML’s pipeline at current pricing, and locking in slots now ensures Samsung won’t be left behind as other customers bid for constrained delivery windows.
On the company figures, ASML reported 32.7 billion euros in net sales for full-year 2025 and earnings of 24.73 euros per share. Management guided 2026 revenue to a range of 34 billion to 39 billion euros with gross margins of 51 percent to 53 percent, while backlog and installed base already sit at elevated levels. More than half of new bookings tie directly to EUV systems, underscoring how the technology mix is reshaping ASML’s top-line composition.
EUV systems carry higher margins than older DUV tools, so a larger EUV share lifts gross profitability and supports management’s longer-term margin targets. ASML’s Q4 showed 13.2 billion euros in new orders already, and layering in the SK Hynix and Samsung commitments materially extends visible revenue into 2026 and 2027. That mix shift also feeds free cash flow, which management is using to fund a multiyear share-buyback program.
The upside is real, but there are risks to weigh. Export controls constrain sales into China, trimming a once-significant market and exposing the company to geopolitical volatility. Shipment delays, longer lead times, or any softening in hyperscaler capex could reduce near-term order growth. Valuation reflects the premium for monopoly exposure — forward price-to-earnings sits near the mid-40s — yet many investors see room for profits to expand if EUV adoption and pricing persist.
For observers of the semiconductor equipment chain, the recent orders are the clearest signal that ASML’s revenue runway has been extended beyond prior guidance. The combination of technical exclusivity, sizeable multi-year customer commitments, and a favorable margin profile forms a powerful commercial picture. Watch incoming quarterly order and backlog disclosures to monitor whether the booked momentum translates into the revenue cadence investors expect.
