Ratios

Computed from the line items above — sparklines read oldest → newest

Ratio Trend 2022-12-312023-12-31
Operating margin -59.5%
Return on capital employed -69.4%-26.6%
Gearing (liabilities / total assets) 47.3%73.3%
Current ratio 1.25x1.20x
Interest cover -95.65x-3.68x

Margins divide P&L lines by turnover. Gearing is liabilities over total assets. Current ratio is current assets over creditors falling due within one year. Interest cover is operating profit over absolute finance costs. Margin ratios are hidden where reported turnover is too small relative to profit to yield a meaningful figure — typical of holding companies whose income is mostly subsidiary dividends rather than trading revenue. Sector-distribution context coming next.
