How these figures are worked out
The net profit for the last 12 months is the four latest reported quarters, so it can differ from the newest year's in the table below.
- Last close: the closing price on the date shown. The page follows the market's close; it doesn't show prices during the session. A price older than the market's latest close, or a last trade that isn't a close, is labelled as the last price, with the session it is from.
- 1-year range: the lowest and highest prices traded during the sessions of the last year (intraday), so they can lie outside the closing prices.
- Market cap: the last close times the shares in issue. It is n/a when it doesn't agree with the company's own reported figures (for example a depositary share counted as an ordinary share).
- P/E: the last close divided by earnings per share over the last four reported quarters, the profit that belongs to the company's shareholders per share, as the company reports it. So P/E can differ from market cap divided by the net profit shown (a different share count, or the profit before minority interests; where they differ by more than 10%, a note under the figures gives both). A company that reports only once a year has its latest year's earnings, and the P/E names that year; when that year ended more than about 15 months before the close, P/E is n/a. A loss has no P/E. Above 1,000 it is n/a.
- EBITDA margin: operating profit before depreciation, interest and tax (and before other income), as a share of revenue in the latest reported year, the table's last column.
- Net margin: net profit as a share of revenue in the latest reported period. Return on equity, the margins and debt to equity each use inputs from that one year; if one input is missing for it, the figure is n/a. When that year ended more than about 15 months before the close, they are n/a too.
- Dividend yield: every dividend per share with an ex-date in the 12 months to the last close, special dividends included, as a share of that close. n/a when the company's dividends couldn't be read.
- n/m: not meaningful. A margin or return beyond ±1,000% comes from revenue or equity near zero, so it is not shown as a number.
