Ernst & Young Global Limited, widely known as EY, is a premier British multinational professional services network headquartered in London, United Kingdom. As one of the prestigious "Big Four" accounting firms—alongside Deloitte, KPMG, and PricewaterhouseCoopers—EY operates as a massive, globally integrated network of member firms structured as separate legal entities to comply with varying local ownership regulations. The organization traces its foundational roots back to the early 20th century through the pioneering work of Scotsman Arthur Young and American Alwin Ernst, who established their respective accounting firms in 1906 and 1903. The modern partnership was officially forged in 1989 through the high-profile merger of Ernst & Whinney and Arthur Young & Co. Initially operating under the name Ernst & Young, the firm executed a major global rebranding campaign in 2013, officially shortening its commercial name to the initialism EY. Driven by its core corporate purpose, "Building a better working world," EY provides a comprehensive suite of professional capabilities divided across four main integrated service lines: Assurance, Tax, Consulting, and Strategy and Transactions. Its Assurance division encompasses statutory financial audits, forensic accounting, integrity services, and climate change and sustainability advisory. The Tax vertical manages complex portfolios involving transfer pricing, international tax compliance, and tax technology transformation. Through its expansive Consulting and advisory segments, including its specialized strategy arm EY-Parthenon, the firm delivers high-impact insights on corporate restructuring, digital transformation, supply chain optimization, and cybersecurity. In recent years, EY has unified its technological innovations under the EY.ai platform, leveraging artificial intelligence to drive predictive modeling, cloud architecture, and data analytics for its clients. The scale of EY's global footprint extends across more than 150 countries and territories, operating out of approximately 700 offices sub-divided into major geographic execution blocks, including the Americas, EMEIA (Europe, Middle East, India, and Africa), and Asia-Pacific. As a privately held network, EY's global combined revenues reached approximately US$53.2 billion for the fiscal period ending in 2025, heavily propelled by the rapid commercialization of its advanced digital tools. The network is a major global employer, supporting a workforce of approximately 406,000 professionals worldwide alongside an alumni network exceeding one million individuals. Under the executive leadership of Global CEO Janet Truncale, the organization places a strong emphasis on talent development, structured corporate mobility, and workplace diversity. Consequently, EY has achieved long-standing recognition on major corporate workplace lists, including a multi-decade tenure on Fortune magazine's prestigious list of the 100 Best Companies to Work For.
