HIG Capital wrapped up a busy August with two major milestones: closing its largest middle market lending fund at $5.9 billion and acquiring global media measurement leader Kantar Media from the Kantar Group.

The H.I.G. WhiteHorse Middle Market Lending Fund IV represents the firm’s largest fundraising effort for its direct lending arm, which has deployed approximately $18 billion across U.S. middle market transactions. The fund continues the division’s focus on senior secured loans to companies with EBITDA between $30 million and $100 million.

Stuart Aronson, Executive Managing Director and CEO of H.I.G. WhiteHorse, emphasized the timing: “We believe the coming years will offer a compelling opportunity to serve as a value-added financing partner to both sponsor and non-sponsor middle market companies seeking private debt solutions.”

The Kantar Media acquisition adds a London-based analytics provider operating in over 60 global markets. The company delivers audience measurement, cross-media analytics, and media validation tools to brands, agencies, and media organizations worldwide.

Patrick Béhar, CEO of Kantar Media, described the transaction as enabling the company to “accelerate innovation on behalf of our clients, partners, and teams around the world” while maintaining operational independence.

These deals reflect HIG Capital’s active investment strategy across multiple sectors. The Miami-based firm has simultaneously recruited four senior professionals from Morgan Stanley’s private equity secondaries unit to launch a new GP Solutions Platform targeting continuation vehicles and GP-led transactions.

Founded in 1993 by Sami Mnaymneh and Tony Tamer, HIG Capital manages $70 billion across private equity, growth equity, real estate, direct lending, infrastructure, special situations debt, and growth-stage healthcare investments. The firm operates from 19 offices spanning North America, Europe, Latin America, the Middle East, and Asia.

Fund IV attracted support from a diverse group of limited partners including pension funds, sovereign wealth funds, endowments, and family offices globally. The WhiteHorse division employs 85 credit professionals across the U.S. and Europe, having invested in over 285 middle market companies since inception. Industry analysts view the fund’s successful close as evidence of continued investor confidence in middle market lending strategies.
