Multiples use the close of each date against the financials that were publicly filed by that date (quarterly reports assumed available 45 days after quarter end; annual figures 90 days). Share count is today's — per-date share counts are not reconstructed, so market cap around buybacks or issuance is approximate. A dash means the trailing figure was negative or not reported — no value is imputed. Source: KRX closes, DART consolidated filings.
