Deloitte is a network of legally separate member firms coordinated by Deloitte Touche Tohmatsu Limited (DTTL), which itself does not provide services to clients. For the fiscal year ended 31 May 2026 the network reported aggregate revenue of US$74.5 billion, up 5.7% in US dollars and 3.8% in local currency, with nearly 500,000 people in more than 150 countries and territories. Transformation work sits mainly in two consulting businesses: Strategy, Risk & Transactions, whose revenue grew 4.4% in local currency, and Technology & Transformation, which grew 2.5%. Deloitte does not publish a US-dollar revenue figure for either business, so the headline total also includes Audit & Assurance and Tax & Legal.
