Reported financials
Figures are as filed with the Korean regulator, in billions of won (KRW bn). We do not convert to dollars — an exchange rate would be a number we made up, not one the company reported.

Ratios, year by year
Each ratio is computed inside its own year. A dash means the input was missing or the denominator was zero — not that the value is zero.

These are arithmetic, not judgements. We do not say whether a margin is good or bad, and we do not rank companies against each other.
