What EY does
EY (Ernst & Young) is one of the Big Four global professional services organizations, operating through a network of independent member firms coordinated by Ernst & Young Global Limited, a UK company limited by guarantee, with Ernst & Young LLP as the US member firm. Founded in 1989 from the merger of Arthur Young & Co. and Ernst & Whinney, EY reported global revenue of US$53.2 billion in FY2025, a 4% year-over-year increase. The firm delivers audit and assurance, tax advisory and compliance, consulting, and strategy and transactions services through EY-Parthenon to multinational corporations, financial institutions, governments, healthcare organizations, private equity firms, and technology, media, and consumer companies across more than 150 countries and 700+ offices.
EY's core service lines are increasingly delivered through proprietary technology platforms anchored by EY.ai, the unifying AI platform, and EY.ai Agentic Platform, an enterprise-scale agentic AI operating system co-engineered with Microsoft and NVIDIA that serves 400,000+ professionals, enables 50,000+ agents, and reports 80%+ user adoption. EY Canvas is the global audit platform being retooled with a multi-agent AI framework targeting full audit coverage by 2028. EYQ is the firm's private GenAI ecosystem, complemented by the EY Intelligent GCC Solution Suite, the EY Physical AI Platform with the EY.ai Lab, the EY Blockchain Privacy Sandbox (built on the Starlight ZKP compiler), and EY Nightfall, a zero-knowledge privacy protocol integrated into Starknet. Annual AI-related investment exceeds US$1 billion and AI consulting revenue grew 30% in FY2025.
EY generates revenue through project-based and recurring enterprise engagements across audit, tax, consulting, and strategy/transactions, with multi-year contracts priced by scope, complexity, and team size. Go-to-market is partner-led and relationship-driven, with regional industry practices selling into large enterprise, government, and institutional clients; flagship channels include the Entrepreneur of the Year program, the global newsroom, EY Insights thought leadership, and major event sponsorships (e.g., Bermuda Risk Summit, World Economic Forum). Recent strategic moves include three acquisitions (Fabernovel 2022, Ignite Strategic 2024, Qiado 2026), core co-engineering partnerships with Microsoft and NVIDIA, an 8% central headcount reduction under CEO Janet Truncale, and concurrent leadership transitions across US, Spain, and major US offices.
