PwC had strong gains in healthcare, tech, and China, matching some of the biggest trends of the 2018 IPO market. Ernst & Young audited 10 more deals than last year, but slipped to #2 with 45 offerings totaling $15.3 billion, a 29% increase by deal count and a 33% increase in proceeds.

Deloitte and KPMG remained at #3 and #4 respectively; while they added more deals than last year, the cumulative IPO proceeds raised by their clients declined.
