INSIGHT

Huge Revenue From Very Few High-Value Machines

  • ASML generated ~€21bn revenue and ~€6.5bn operating profit in 2022 while selling only ~345 machines; top systems cost >€150m each.
  • It's a low-volume, high-ticket business where a handful of customers buy complex kit.
INSIGHT

Custom Components Created A Moat Around EUV

  • ASML dominates EUV because the technology required bespoke components (e.g., tin-droplet laser plasma sources, special mirrors) that didn't exist off the shelf.
  • ASML invested >€10bn R&D over 25+ years and acquired key suppliers (e.g., Cymer) to make the system work end-to-end.
INSIGHT

Machines Last Decades And Upgradeable In Field

  • ASML machines have extremely long operating lives; ~90% of sold lithography machines from the last 30 years remain in operation.
  • ASML monetizes longevity by offering field upgrades and service that materially extend machine productivity.
