Going concern
Affirmed

“The directors have prepared a cash flow forecast which shows that they expect the Company to be able to meet its operating obligations from available cash resources and the group's European cash pooling system as they fall due. The Directors have received confirmation from Charles River Laboratories International, Inc. it's ultimate parent entity, that it will provide financial support as required for the Company to meet its financial obligations as they fall due for at least twelve months from the date of signing these financial statements. In conclusion, they continue to adopt the going concern basis in preparing these financial statements.”

Year-on-year

FY2023 → FY2024 · period ending 2024-12-28 vs 2023-12-30

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
