Year-on-year

FY2023 → FY2024 · period ending 2024-12-31 vs 2023-12-31

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

“The directors of WithSecure Limited have considered forecasted results for the business, taking into account its current and planned business activities and the markets in which it operates. The forecasts, along with a formal letter of support provided by the parent company, WithSecure Oyj, indicate sufficient funds are available for the Company to be able to continue in operational existence for the foreseeable future, being a period of at least twelve months from the date of signing these financial statements. The directors accordingly continue to prepare the financial statements on the going concern basis.”
