Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
Ratios
Computed from the line items above — sparklines read oldest → newest
| Ratio | Trend | 2019-01-01 | 2019-12-31 | 2020-12-31 | 2023-12-31 | 2024-12-31 |
|---|---|---|---|---|---|---|
| Return on capital employed | — | — | — | -94.0% | -148.4% | |
| Current ratio | — | — | — | 8.44x | 7.60x | |
| Interest cover | — | — | — | -6.60x | -1.36x |
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.

“As of 31 December 2024, the Consolidated Balance Sheet had cash reserves of £5.9m. Subsequent to the year end Ultromics raised $35m from its Series C transaction. In all cases, the group will have sufficient funds to meet its liabilities as they fall due during the 12 month period ending 30 June 2026, the going concern assessment period.”

Significant events
- “On 13 June 2025, the company exchanged on its Series C financing transaction raising $35m. On receipt of $30m of the total $35m the convertible loans will convert into Series C shares with the full $35m needing to be funded within 14 business days of exchange.”
- “In July 2025, the Group intends to pay employee bonuses (c. £282k excluding employer payroll taxes) in relation to the second half of 2024. This bonus is contingent on completion of the Series C fund-raise and as there was no legal or constructive obligation as at 31 December 2024 no accrual was included.”
