Ratios

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

Ratio Trend 2023-12-312024-12-312025-12-31
Return on capital employed -37.3%-29.0%-33.9%
Gearing (liabilities / total assets) 12.7%16.7%13.2%
Current ratio 13.13x14.63x12.53x
Interest cover -61.08x-95.33x

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.

Going concern
Affirmed

“At 31 December 2025, the Company had cash and cash equivalents of $628.1 million and the directors estimate the Company's existing cash and cash equivalents at the date of approval of these financial statements is sufficient to fund the Company's operating expenses for the foreseeable future for at least 12 months from the date of that approval and that is therefore appropriate to prepare these financial statements on a going concern basis.”
