Doosan Enerbility: Sharp one-month share price drop alongside thin profits and a high earnings multiple

Thesis

The data supports a picture of a large machinery company with stable-to-growing revenue but modest profitability. Trailing revenue is ₩17.7T and operating income is ₩896.9B (5.1% margin), yet net income is only ₩181.1B. The market value of ₩45.8T is therefore large relative to earnings, with a trailing P/E of 252.9 and P/B of 5.6.

The share price is down 21.3% over one month, 2.3% over three months and 4.0% over one year. It sits 48.6% below the 52-week high and 25.4% above the 52-week low. The data does not explain the recent fall: no news headlines are provided, and investor flow, foreign ownership and short balance data are not available. Filings show repeated major sales or supply contract disclosures (including amendments on 2026-10-06, 2026-10-01 and 2026-09-01), several IR events, and a response to a rumour or news report on 2026-09-17. The contents of these filings are not in the data, so their effect cannot be assessed.
