Lasertec Corporation 6920
Lasertec — Japan's most-traded stock at $23B market cap — is a colossal accounting fraud whose defective EUV mask-inspection tool and sham 'Innovation Park' mirror Olympus and Toshiba before collapse.
Thesis
Scorpion Capital alleges that Lasertec — Japan's most actively traded stock at a $23B market cap, touted as 'Japan's ASML' for its EUV-mask-inspection monopoly — is running a colossal accounting fraud on the scale of Olympus and Toshiba, driven by inflated inventory and aggressive revenue recognition while cash conversion has collapsed to 28-30% (versus ASML's 130-180%). A five-month investigation with 20+ sources claims the flagship ACTIS EUV tool is fundamentally defective — tin contamination, unstable Ushio-sourced plasma light, 60-65% uptime — and that the 2023 A300 'next-generation' launch is a sham whose new 'Urashima' source is actually a rebranded, decade-old Russian Isteq product. The Yokohama 'Innovation Park' is a Potemkin finished-goods warehouse. The required inventory writedown of 65-70% would erase ~85% of retained earnings and ~70% of cumulative post-2019 profit — far larger, relative to size, than Olympus or Toshiba.
SCQA
Lasertec is Japan's most actively traded stock at a $23B market cap, hailed as 'Japan's ASML' for its near-monopoly on EUV-mask inspection equipment sold to TSMC, Intel, and Samsung.
A five-month Scorpion investigation with 20+ sources alleges classic inventory-and-revenue fraud, a fundamentally defective ACTIS tool (tin debris, 60-65% uptime), a rebranded Russian light source sold as new, and a Potemkin Yokohama innovation park.
Scorpion is short the stock and argues a ~65-70% inventory writedown is inevitable, forcing restated earnings and full disclosure that the EUV franchise is defective and losing customers to KLA and DUV substitutes.
The implied writedown erases ~$700-750M and ~85% of retained earnings — a hit proportionally larger than Olympus (2012) or Toshiba (2014-16) and, Scorpion argues, far more than the $23B market cap reflects.
The three reasons
- 1
Inventory-and-revenue fraud will force a 65-70% writedown, wiping ~85% of retained earnings.
- 2
Flagship ACTIS EUV tool is fundamentally defective — tin debris, 60-65% uptime, customers furious.
- 3
Yokohama 'Innovation Park' is a Potemkin finished-goods warehouse, not an R&D site.

Notes
Japanese-language summary of Scorpion Capital's longer English investigative report on Lasertec (TYO:6920), dated 5-Jun-2024. Section headers reference original-report pages 10-334, so this is a distilled digest rather than the full deck. Format is a text-dense memo with hanging bullets, not a slide deck — visual craft is minimal. Strong SCQA architecture: Olympus/Toshiba analogy, CEO-quote contradictions (Okamoto earnings call on Innovation Park), surveillance photos, IR-interview traps ('no finished goods' contradicted by shrink-wrapped $50M tools visible on site), and peer-gap inventory math against ASML/AMAT/LAM/TEL/KLA. Five-month investigation, 20+ expert interviews. Stake not disclosed as percentage; Scorpion simply states it is short. Campaign outcome left 'unknown' at extraction time.
