Deloitte has outlined plans for a major regional combination under a new Europe, Middle East and Africa (EMEA) enterprise, bringing together member practices with combined revenues of €20bn.

The new structure, called Deloitte EMEA, is scheduled to come into effect on 1 June 2026.

The combined entity will include 16 companies from the region. They will coordinate more closely under the new framework, with each retaining responsibility for the services it provides in its own jurisdiction.

Together, the participants operate in more than 80 countries. They are led by 6,000 partners and employ 132,000 professionals across the region.

Deloitte said the EMEA company will serve the regional market at greater scale through tighter strategic alignment between members.

The new organisation will focus on shared priorities supported by regional investment in innovation, technology platforms and skills development.

Over the next four years, Deloitte EMEA expects to deploy more than €1.5bn in additional investment. Funds will be directed to areas including generative AI, sovereign cloud capability, sector-specific solutions and technologies designed to help clients manage fast-changing markets.

Richard Houston, currently CEO of Deloitte North and South Europe and Deloitte UK, will become CEO of Deloitte EMEA.

Deloitte Germany CEO Volker Krug will take on the position of deputy CEO.

Sami Rahal, CEO of Deloitte Central Europe, will serve as chair, while Liesbeth Mol, chair of Deloitte North and South Europe, will act as deputy chair.

Houston stated: “Deloitte EMEA uniquely strengthens our ability to invest at scale across borders to accelerate innovation in areas that matter most to our clients.

“It builds on our market-leading local partnerships while supporting collaboration at a regional level.”

The EMEA combination follows several years of closer regional cooperation including joint investment initiatives in areas such as banking transformation, energy transition and mergers and acquisitions capabilities.
