Andersen Group buys Andersen Mexico and five US consulting firms in $34.5m revenue push

Professional services consolidation is accelerating across North America, with integrated advisory firms competing to serve multinationals that need tax, legal and consulting support under one engagement. Against that backdrop, Andersen Group has agreed to acquire Andersen Mexico alongside five US-based Andersen Consulting firms, deals the company says will add approximately $34.5m in annualised revenue. The six transactions are expected to close in the fourth quarter of 2026, taking total annualised revenue from acquisitions since Andersen's first-quarter update to roughly $67m.

A cross-border play anchored in Mexico

The Andersen Mexico acquisition targets what the firm describes as one of North America's most important markets, where demand for integrated tax, legal and business advisory services has grown alongside the region's role in cross-border commerce. Andersen says the deal will broaden its capacity to support multinational corporations and businesses in the expansion phase. Chairman and chief executive Mark Vorsatz said the company continues to build "one of the world's leading integrated professional services organisations," with the Mexico deal strengthening its tax and legal platform in a market the firm regards as key to that ambition.

Five US firms fill the consulting stack

The domestic side of the announcement adds Clareo, BD Emerson, Daniels Consulting Group, Endeavor Management and Zenger Folkman to Andersen Consulting's roster. The five firms together are intended to expand capability across AI and digital transformation, strategy, innovation and growth, enterprise and finance transformation, cybersecurity, and human capital and organisational transformation. The discipline list spans the advisory areas where corporate clients have concentrated spending: technology adoption, workforce redesign and finance process improvement. Andersen Consulting counts more than 37,000 professionals globally.

The macro read-through and what follows

The broader cycle here is client-side pressure to consolidate vendors. Multinationals managing tax-residency decisions, digital overhauls and supply-chain restructuring prefer fewer counterparties, which tilts the demand environment toward firms that can deliver across practice areas in a single relationship. Vorsatz framed the rationale in those terms, describing the acquisitions as a way to deliver integrated solutions to clients worldwide and strengthen Andersen's competitive position. Andersen says it is exploring further acquisitions in tax, legal, valuation and consulting across key markets. On balance, the $67m revenue figure from acquisitions since the first-quarter update signals an active deal cadence. The macro caveat is that advisory budgets remain sensitive to the rate environment, and if corporate spending tightens into the fourth quarter of 2026, newly acquired revenue will face conversion pressure before it can be fully absorbed.
