EY overview

EY, formerly known as Ernst & Young, is a provider of assurance, tax, transaction and advisory services, and is considered one of the 'Big Four' accounting firms.

Within Assurance, the company offers audits, financial accounting advisory services, and forensics. For Tax, it offers transfer pricing, advisory, technology and transformation, and more. Its Consulting services split into four sub-categories: Risk, IT Risk & Assurance, Performance Improvement, and Actuarial. Finally, within Strategy, it offers capital transformation services, including M&A and Corporate Finance. EY offers its services across a number of industries, including Auto, Health, Technology and Entertainment.

Within insurance it offers advisory services across operations, finance and risk management, as well as fraud investigation and regulatory compliance work and IT advice. It also offers Assurance services, Tax services and Transaction Advisory services within insurance.

EY reported combined global revenues of $37.2bn in FY 2020 (ended June). During its FY 2020, EY launched its NextWave strategy, which aims to bring greater focus on long-term value creation with plans for investments of US$1.5b in EY people, technology and audits in FY21.

In late 2020, EY announced it had created a dedicated Microsoft Services Group - the first of the 'Big Four' firms to do so - which will build on the pair's strategic alliance. It will combine EY's consultancy with Microsoft's Cloud serviced to help clients address digital challenges, particularly those faced as a consequence to Covid-19.

In June 2020 EY announced a collaboration with SAP for industry cloud solutions to help clients' digital transformation. Offering will start with insurance (in late June 2021) and will be followed by banking, life sciences, and energy and resources. The EY insurance industry solutions will help provide ready-to-deploy assets, such as packaged financial reporting on SAP Analytics Cloud.

In July 2021 EY partnered with core insurance operations software provider Fadata. The partnership aims to help insurers bring new products to market faster, and distribute them through digital means.

EY reported global revenues of $40bn in 2021. The company also revealed a three-year investment plan, focused on audit quality, strategy, technology and people.

Headquartered in London, UK, EY has over 700 offices in around 150 countries across the globe, employing 270,000 employees.
