Material uncertainty over going concern
The Directors believe that it remains appropriate to prepare the financial statements on a going concern basis. However, there remains a material uncertainty which may cast significant doubt over the Group's ability to continue as a going concern and to continue realising its assets and discharging its liabilities in the normal course of business.

Ratios
Computed from the line items above — sparklines read oldest → newest
| Ratio | Trend | 2024-06-30 | 2025-06-30 |
|---|---|---|---|
| Gearing (liabilities / total assets) | 68.0% | 51.2% | |
| Current ratio | 1.27x | 1.55x | |
| Interest cover | -38.07x | -44.54x |
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.
