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.

Market capitalisation is what buyers are betting the company is worth. It is not something the company produced, so we never present it as output or productivity.
