Audit opinion
Unqualified (clean)
Going concern
Affirmed

“The Directors consider it is appropriate to prepare the financial statements on a going concern basis. In order to assess the Hydriades IV Limited Group's (the "Group") and the Company's liquidity requirements and trading prospects, a detailed business planning process is completed for review by the Board. This reassesses its long-term strategic objectives and operational plans and the key business issues that the Group faces both now and those anticipated in the future and how the Group proposes to address these issues. On 15 August 2022 South Staffordshire Plc announced that it had been the subject of a criminal cyber-attack. The nature of the attack did not include data encryption or destruction but did include data exfiltration. The Directors of Hydriades IV Limited are therefore satisfied that the refinancing risks within the going concern period have been substantively dealt with and mitigated and the residual risks do not represent a material uncertainty to the going concern assumption.”

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
