We have advised long-standing client RSM UK, the UK's seventh largest accountancy practice, on establishing a new transatlantic partnership with RSM US and RSM Canada.
RSM, a leading provider of tax, audit, and consulting services for mid-market business leaders globally, has created a transatlantic partnership, bringing together its businesses in the UK, Ireland, the US and Canada.
RSM UK is the seventh largest accountancy practice in the UK by turnover. It has 5,420 partners and staff operating across 29 UK offices and its new partnership has brought together 23,000 professionals across six countries, with combined revenues of £4 billion. RSM UK generated revenues approaching £600 million in the year to March 2025, while the US arm reported revenue £2.8 bn in the year to April 2024. The new partnership paves the way to enhance RSM's global client service, accelerate growth, and strengthen talent development across markets.
Our team advising RSM UK was led by corporate partner Andrew Edge and included Paul Thorpe (partner, corporate) and Aria Howorth Oram (senior associate, corporate).
