EY Global

EY Global is a multinational professional services partnership and one of the largest of the Big Four accounting firms. Formed from the merger of Arthur Young's and Alwin C. Ernst's accounting practices, it operates as a global network of member firms in over 150 countries. The organization provides a comprehensive suite of services including assurance, tax advisory, consulting, and strategy and transactions to a vast client base of corporations, governments, and institutions. Its operations are coordinated by EY Global Services Limited, which is based in the United Kingdom.

History

The origins trace back to separate firms founded in the early 20th century by Arthur Young in Chicago and Alwin C. Ernst in Cleveland. These entities evolved into the international accounting firms Arthur Young & Company and Ernst & Whinney, which merged in 1989 to form Ernst & Young. A significant strategic shift occurred in 2013 when the organization rebranded to EY, emphasizing its broader service portfolio beyond traditional accounting. Key historical milestones include its role in the adoption of International Financial Reporting Standards and navigating major regulatory changes like the Sarbanes–Oxley Act.

Organization and structure

EY Global operates as a network of legally distinct member firms under the common EY brand, coordinated by the global entity EY Global Services Limited. The governance structure is led by a Global Executive and overseen by a Global Board, with the current Global Chairman and CEO being Carmine Di Sibio. The organization is divided into four primary service lines: Assurance, Tax, Consulting, and Strategy and Transactions. Geographically, it is segmented into areas such as Americas, EMEIA (Europe, Middle East, India and Africa), and Asia-Pacific, with major hubs in cities like London, New York City, and Hong Kong.
