Mid-market investment bank Houlihan Lokey is gunning to be the most active M&A adviser in Europe after a transformative acquisition that adds 170 dealmakers to its ranks in the region.

The Los Angeles-based bank’s $600m purchase of GCA, a Tokyo-listed technology-focused advisory firm, is Houlihan Lokey’s 10th acquisition within six years. It is also its biggest yet — parachuting in 500 dealmakers globally and nearly doubling headcount to 350 bankers in Europe.
