About

EY's roots trace to 1903 when Alwin C. Ernst and Theodore Ernst founded Ernst & Ernst in Cleveland, Ohio; the modern EY emerged from the historic 1989 merger of Ernst & Whinney and Arthur Young & Co. EY's integrated service model spans assurance (the highest-revenue segment among Big Four peers), consulting, strategy and transactions through EY-Parthenon (created via the 2014 acquisition of The Parthenon Group), and tax services. In July 2024, Janet Truncale became EY's Global Chair and CEO, the first woman to lead the firm. In 2025, EY launched the EY.ai Agentic Platform in partnership with NVIDIA, deploying 150 AI agents supporting 80,000 EY professionals across tax, risk, and finance domains to surpass 3 million tax compliance outcomes annually.
