Historical Evolution
The roots of EY stretch back to 1849, making it a deeply established institution in the financial world. The modern entity was formed through the merger of Ernst & Whinney and Arthur Young & Co. in 1989. Over the decades, the firm has undergone significant rebranding and structural changes to adapt to the evolving global economy.
In 2013, the firm officially rebranded from Ernst & Young to the shorter, more modern EY. Throughout its history, the firm has expanded its footprint significantly. For instance, in 2006, EY became the only Big Four member to have two member firms in the United States following the inclusion of Mitchell & Titus, LLP, the largest minority-owned accounting firm in the US (though this membership ended in 2015).
Growth and Expansion
EY continues to invest in regional hubs to support its global reach. Recent expansions include a $4.4 million professional services center in Louisville, Kentucky, and the announcement of an IT and technology hub in Nashville, Tennessee, aimed at creating hundreds of regional jobs.
