The blade, not the razor.
CLASSYS sells skin-tightening devices to clinics at razor-thin economics, then earns for years on the single-use cartridges every treatment burns. Revenue tripled in five years while operating margin never left 50% — the exact trick the Western rivals who sold 'just the machine' couldn't manage. Two of them went bankrupt proving it.

AgribusinessEverything but the price.
Harim owns every link — the feed mills, four hatcheries, six hundred farms, the most automated slaughterhouse in Asia. Across fifty-four quarters its average operating margin is 0.6%, the lowest of Korea's top-500 food companies. A story about why owning the whole chain is not the same as owning the part that sets the price — and the ₩412 billion the wider group is spending to escape it.

GamingThe loss they chose.
Nexon Games could have shown a profit in 2025. Instead it pushed R&D to 47% of revenue, let sales fall by a third, and posted a ₩60bn operating loss — a deliberate bet that an unshipped pipeline will replace a hit that has already faded. One ticker over sits Shift Up: the same Korean gacha-and-console archetype, the opposite result. The distance between the two is the entire investment question.

Beauty & CosmeticsThe pioneer who missed the wave.
Manyo Factory helped invent the clean/vegan, one-hero, export-online playbook that built K-beauty's breakout brands. Then a later cohort ran that same playbook to two-to-three times its scale while Manyo went flat. In 2025 a private-equity sponsor reset the cost base and the operating margin snapped back to 22.5% in a single quarter. The harder question — the one an acquirer is really underwriting — is whether anyone can manufacture a second hero before the cost savings run out.
