RSM a provider of consulting, tax and assurance services for the middle market has reached an agreement in principle for RSM Mexico to join its transatlantic partnership. This marks an important step in expanding the partner-owned platform across key markets where its clients do business.
RSM’s transatlantic partnership will span entities in the U.S., the UK, Canada, Ireland and Mexico, with integrated teams in India and El Salvador, aligning more than 25,000 professionals and generating aggregate annual revenue of more than $5 billion (USD).
This addition will further advance RSM’s strategy to build a multinational platform that delivers consistent, high-quality service across geographies. It comes at a time when middle market companies increasingly need cross-border advice to navigate shifting supply chains, nearshoring, artificial intelligence, private investment and other forces reshaping global business.
Brian Becker, CEO of RSM’s transatlantic partnership, commented: “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 U.S., the UK, Canada and Ireland represents continued progress toward our ambition of building a $10 billion (USD) multinational partner-owned platform dedicated to serving dynamic, growing businesses around the world.”
Alfonso Elias, managing partner, RSM Mexico, added: “Joining the transatlantic partnership will strengthen our ability to support our clients as they transform for the future. 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 U.S., Canada, the UK and Ireland.”
Established on January 1, 2026, the transatlantic partnership was designed to create a partner-owned platform focused on delivering quality service, developing talent and accelerating growth. The structure aligns governance, financial incentives and client delivery, supporting more coordinated investment and consistent client experience across markets.
The agreement remains subject to definitive agreements, receipt of necessary corporate and regulatory approvals and the satisfaction of various closing conditions.
The transatlantic partnership, governed by a Delaware LLP, provides a centralized governance function based on certain authorities delegated by RSM US and RSM UK. This partnership does not serve clients or engage in other business activities. Clients are served and business is conducted by the individual firms—RSM US, RSM Canada, RSM UK and RSM Ireland—which are separate legal entities for legal, regulatory and tax purposes.
