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
“The Directors have, at the time of approving the financial statements, considered the applicability of the going concern basis in the preparation of these financial statements. This included a consideration of IDS Holdings Limited's cash reserves (due to intercompany loan funding) and internal forecasts of the financial results. Even when considering an extreme worst-case scenario, IDS Holdings Limited and IDS Limited still have sufficient cash reserves available for at least twelve months from the date of approval of these financial statements. In addition, IDS Holdings have received a letter of support from Revvity Inc, their ultimate parent company, to ensure financial support is provided going forward. As such, the Directors have a reasonable expectation that the Company has adequate resources to continue in operational existence for the foreseeable future.”
