Gartner stated that Deloitte’s market share grew at 9.9% or US$39.5 billion.

“We believe being recognised once again by Gartner is a testament to our commitment to creating enduring value together with our clients.

Our multidisciplinary approach enables us to guide clients through their most critical decisions and transformations. By combining deep sector insight with analytical rigor and innovation, we help organizations build resilience, seize opportunity, and create lasting impact," said Nicolai Andersen, Deloitte Global Strategy, Risk & Transactions leader.
