Going concern

Affirmed

“The financial statements are prepared on a going concern basis. The company had net current liabilities of £115.4 million as at 31 December 2024 (2023: assets £120.5 million) which included a bank overdraft of £104.5 million (2023: £162.1 million) and continues to have access to a group cash pool to fund day to day operations. The directors have received confirmation from the ultimate parent company, Iron Mountain Inc., of its continuing support for a period of at least 18 months from the date of approval of these financial statements. ... The directors, having assessed the financial position and prospects for the company, including the current cash balances of the company compared to the likely demands on these cash balances as per forecast cashflows, are satisfied that the company has adequate resources to continue to operate as a going concern throughout the twelve months following the date of approval of these financial statements. ... Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”

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
