EY (Ernst & Young) - statistics & facts
EY, previously known as Ernst & Young, has consistently been one of the leading professional services firms worldwide. As one of the Big Four accounting firms, EY offers services like auditing, consulting, tax advice, and financial advisory. The firm has been active in many countries and works with businesses of all sizes to manage finances and improve operations across different industries. With these accomplishments, EY established itself as a member of the Big Four and had the third-highest revenue of the Big Four accounting/audit firms in 2023. To demonstrate the scale and influence of these firms that also include Deloitte, PwC, and KPMG, the combined revenue of the Big Four reached over 200 billion U.S. dollars in 2023.
As revenues, number of employees, and the global reach of EY have continued to increase, the firm has indicated signs of even greater expansion. When this is combined with the growth of the other three members of the Big Four, the consulting services industry looks to be in a position of further diversification and influence.
Ever-increasing revenue streams
When the revenue of EY is broken down by service line, the firm has served four different categories. These categories span through assurance, tax, advisory, and transaction advisory, with EY standing as a partner to organizations seeking to navigate themselves through disruption. Assurance has consistently generated the highest annual revenue for the company, followed by tax and advisory services, with transaction advisory services grossing the lowest revenue. Over the last decade, advisory services have seen the greatest increase in turnover, up by roughly 10 billion U.S. dollars when compared to 2009. The combined revenue of EY has increased year-on-year since 2010, and reached a record of approximately 51 billion U.S. dollars in 2024.An established player in the world of accounting and consulting
EY has a global footprint, with a presence in over 150 countries and territories. This expansive reach allows EY to tap into diverse perspectives, insights, and resources from around the world, enriching the solutions and services it offers to clients. EY breaks this mass expanse down by combined revenue by region when it comes to their business model. These regions are the Americas, Europe, the Middle East, India and Africa (EMEIA); and the Asia-Pacific region. EY has consistently generated the most revenue in the EMEIA region, followed by the Americas. The combined revenue from the Asia-Pacific region and Japan represented less than 15 percent of the total revenue grossed worldwide. The region with the highest number of company employees was the EMEIA region in 2024, again followed by the Americas. EY had the second highest number of employees out of the Big Four firms in the same year, demonstrating the global reach of the firm.As revenues, number of employees, and the global reach of EY have continued to increase, the firm has indicated signs of even greater expansion. When this is combined with the growth of the other three members of the Big Four, the consulting services industry looks to be in a position of further diversification and influence.
