“They will benefit from additional capabilities, insights and expertise, including enhanced access to a full suite of consulting services tailored to the needs of mid-sized businesses.
“Clients with global operations will also benefit from our closer connectivity with the US, Canada, the UK and Ireland.”
The transatlantic partnership, launched on 1 January 2026, was set up as a partner-owned platform focused on service quality, talent and growth.
RSM transatlantic partnership CEO Brian Becker said: “RSM Mexico will expand our transatlantic partnership and strengthen our ability to support clients operating up and down North America’s most important trade routes.
“Adding Mexico to our already robust partnership between the US, the UK, Canada and Ireland represents continued progress toward our ambition of building a $10bn multinational partner-owned platform dedicated to serving dynamic, growing businesses around the world.”
The agreement is subject to definitive documentation, required corporate and regulatory clearances, and completion of closing conditions.
