Deloitte’s global revenues have come in at $31.3 billion, up 8.6 per cent to reach the highest revenue growth in four years.

Member firms saw the highest revenue growth since 2008, driven by “exceptional” results in Asia Pacific, the Americas and developing markets.

All business service lines grew, with financial advisory and consulting experiencing double digit growth – 15 per cent and 13.5 per cent revenue growth. Financial advisory saw cross-border and acquisitions work driving fees. Consulting saw a range of regulatory and market changes fuel need for advice – including IT services and finance and HR transformation.

Audit grew six per cent, with risk services in particular proving popular. Tax and legal grew four per cent. Key industries included energy and resources (24 per cent growth), life sciences and healthcare (13 per cent), consumer business and transportation (11 per cent) and financial services (10 per cent).

The growth across industry and business lines was achieved despite challenging market conditions around the world, particularly in Europe. Growth was largely driven by Deloitte’s ability to provide a consistent suite of tools across member firms.

“In a challenging economic environment, $1.4 billion of Deloitte’s $2.5 billion aggregate growth in the past year came from member firms in the three largest economies in the world,” Deloitte global CEO Barry Salzberg said.

“Despite the challenging economic times, Deloitte has remained resilient and continued to achieve revenue growth” Deloitte Malta chief executive Paul Mercieca added.
