Rob Donaldson – CEO of RSM UK

The new structure has received near-unanimous approval from partners at both firms.

The partnership aims to create a unified, partner-owned platform to better serve global clients, develop talent, and accelerate growth. This will be achieved through aligned governance, shared financial incentives, and a common approach to client service and future investment.

The integrated entity will employ 23,000 professionals across the UK, the US, Canada, Ireland, India, and El Salvador, generating combined annual revenues of $5 billion (c. £3.75bn). Brian Becker, currently the managing partner of RSM US, will lead the new transatlantic partnership as its CEO.

Mr Becker stated the move will create a partnership with “shared values, enhanced reach and connected resources”, positioning the firm to serve the evolving needs of the middle market. He added that the new structure is designed to be scalable, with a future ambition to support a $10 billion multinational platform.

Rob Donaldson, CEO of RSM UK, described the partnership as a “defining moment” and a continuation of the UK firm’s recent transformation. He noted that closer collaboration over the past year has already resulted in “tangible client wins” that the firms could not have secured independently.

Both firms will continue to operate as independent members of the global RSM International network.
