RM's new CEO, Mark Cook, acknowledged in January that there is "much more to be done" to nurse the schools technology and resources supplier back to full health following a challenging 2022. Fiscal 2022 results were imminent as this report went to press, but revenues for its year to 30 November 2021 hit £211m, with tech arm RM Technology generating £64.6m of the total. The LSE-listed outfit reached an agreement to sell RM Technology's RM Integris and RM Finance software businesses in November as part of plans to trim debt.
