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

- Going concern
- Affirmed
“Under both the base case and the severe but plausible downside scenario, the forecasts indicate that the company will have sufficient liquidity to continue to settle its liabilities as they fall due for a period of at least 12 months from the date of approval of the financial statements. Consequently, the Directors believe it is appropriate to continue to prepare the financial statements on a going concern basis.”

Significant events
- “The loss for the year after taxation amounted to £4,585,776 (year ended 31 March 2024 loss of £4,070,916). The results reflect a combination of reduction in requirements of some Diagnostics Enzyme products and demand growth from some Diagnostic Enzyme customers which is impacting mix and profitability of the Enzyme business, which is being addressed through pricing and cost control measures.”
- “We are part way through a budgeted significant investment (£20M) to enable us to grow our Biopharma CDMO (Contract Development and Manufacturing Organisation) business. R&D and QC labs have been completed and are occupied and the main part of the investment (£18.5M) in a Bio Pharma production facility is partially completed and expected to be commissioned, validated and operational in FY26.”
