Significant events
- “This financial year was reduced to March 2025 (10 months) to align with the Halma reporting timetable.”
- “Following the acquisition of the company by Halma plc in April 2024, it was decided to amend the company fixed asset capitalisation and depreciation policies to align with that of the parent group. This resulted in a one-time adjustment to depreciation in the period of £97,228.”
- “Ultimate controlling party, Halma Public Limited Company, are completing a group rationalisation exercise, in which the holding companies of the existing MK Test Group (Jam Topco Limited, Jam Bidco Limited, MK Test Group Limited and MK Test Holdings Limited) are to be liquidated post-year end. The intercompany debts between M.K. Test Systems Ltd. and these group entities are to be extinguished and so these have been provided in full in the year ended 31 May 2025.”
