In a clear sign of how artificial intelligence (AI) is reshaping the professional services landscape, Ernst & Young has announced combined global revenues of US $53.2 billion for its fiscal year ending June 2025, marking a 4% increase over the prior year amid increased demand for AI-enabled offerings and consulting services.
The latest financial results reveal that the London-headquartered Big Four firm not only maintained steady overall growth but also significantly expanded its AI-related revenue streams, highlighting how advanced technologies are being embedded across every key service line. EY’s financial performance for FY25 reflects strength in tax, consulting, assurance and digital transformation services at a time when organizations across the globe are racing to adopt AI tools and strategies to remain competitive.
According to firm data, EY achieved a substantial year-on-year increase of approximately 30% in AI-related revenue, driven by a blend of enterprise-wide transformation projects, AI governance frameworks, and strategic initiatives that leverage emerging technologies for business advantage. This surge underscores how artificial intelligence consulting and digital advisory work are now pivotal revenue drivers for one of the world’s largest consulting networks.
The firm’s consulting segment grew by more than 5%, while its tax practices increased by roughly 5.5% in local currency, indicating solid demand in areas where AI methods — such as predictive analytics, automation, and machine learning — are being deployed to address complex client challenges. Assurance services also recorded growth, contributing to the firm’s overall performance.
EY’s leadership attributes this success to ongoing investments in AI first platforms, strategic technology alliances, and a collaborative ecosystem that helps enterprises capitalize on digital transformation. While revenue growth of 4% may appear modest, it comes against a backdrop of global economic uncertainty, competitive pressures among the Big Four accounting and consulting firms, and rapid technological change. EY’s ability to grow despite these challenges reflects broader market trends, notably the accelerated adoption of AI across corporate functions from finance and tax to risk, analytics, and operations.
In context, FY25 was a watershed year for EY’s AI strategy. The firm has been building out its in-house AI platforms and capabilities, investing significant capital — including committed annual investments approaching US $1 billion — to develop proprietary tools that help organizations implement and scale AI responsibly and effectively. More than 15,000 EY professionals were involved in AI-centric client engagements in the reporting year, reinforcing the firm’s role as a key AI advisor in global markets.
EY’s performance also reveals how the professional services industry at large is adapting to the digital era. In comparison with other Big Four rivals, such as Deloitte and PwC, which also reported solid revenue growth for FY25, EY’s emphasis on AI and consulting has positioned it as a formidable competitor in high-growth advisory areas.
Janet Truncale, EY’s Global Chair and CEO, highlighted that the growth reflects the firm’s commitment to helping clients navigate a landscape defined by technological disruption, regulation, evolving workforce expectations and geopolitical shifts. She emphasized that EY’s investments in digital transformation, AI governance, and cross-industry solutions are designed to help clients build trust and value in every market.
Looking ahead, EY’s FY25 results underscore not just a strong financial performance but also a strategic pivot toward technology-infused services, positioning the firm to capture future opportunities as enterprises increasingly look to AI to drive efficiency, innovation, and sustainable growth.—
