Affirmed

“The financial statements have been prepared on a going concern basis which assumes that the company will continue in operational existence for the foreseeable future. In making their assessment, the directors have reviewed the balance sheet, the likely future cashflows of the business and have considered the facilities that are available to the company along with their continued support. At the date of approving the financial statements the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future and that the going concern basis of accounting remains appropriate.”

Year-on-year

FY2022 → FY2023 · period ending 2023-09-30 vs 2022-09-30

Each % is (latest − prior) ÷ |prior| for the line item as filed. Periods don't have to be exactly 12 months apart — a long or short period (typical around incorporation or year-end changes) will distort the comparison. Lines a company doesn't report are omitted. About these numbers
