SEOUL & NEW YORK -- New Mountain Capital, LLC (the “Firm” or “New Mountain”), a leading growth-oriented alternative investment firm headquartered in New York, announced the establishment of a new office in Seoul, South Korea. The new office builds on New Mountain’s established presence in Asia, including its Tokyo office, and reflects the Firm’s continued commitment to deepening client relationships in Korea.

The Seoul office will be led by Sangmyung Lee, Director, who joined New Mountain in February 2026 and focuses on client relationships across Asia Pacific, with a primary emphasis on Korea. Prior to joining New Mountain, Sangmyung spent 13 years at Korea Investment Corporation (KIC), the sovereign wealth fund of Korea, where he invested across private equity, venture capital, and private credit through primary, secondary, and co-investment opportunities. He worked closely with leading global GPs and institutional LPs and served as a strategist for KIC’s Private Equity Group. In addition, he served as an external investment committee member for two Korean institutional investors. Mr. Lee will work under Andrew Barous, Managing Director, who leads New Mountain’s client relationship efforts in Asia and is based in Tokyo. Mr. Lee further expands the Firm’s client services footprint across Asia, joining Yuuki Akasu, Director, who is based in Tokyo and focuses on client relationships in Japan.

“We are pleased to open our Seoul office as we build on our long-standing partnerships in Korea,” said Adam Weinstein, New Mountain’s President and Chief Operating Officer. “We have enjoyed successful partnerships with high-quality local institutions, and we believe our focus on ‘defensive growth’ industries will continue to resonate with investors in Korea and globally.”

Founded in 1999, New Mountain has approximately $60 billion in assets under management across its private equity, credit and net lease investment strategies. Since inception, the Firm has focused on building great businesses across a range of carefully selected, non-cyclical sectors and has delivered a consistent track record of strong performance. While expanding its presence in Korea and across Asia, New Mountain will continue to focus its investment activity on defensive-growth middle-market companies based in North America.

“We began building institutional relationships in Korea and Asia more than 20 years ago, and today, we work with over 70 partners across the region,” said Andrew Barous. “With this new Seoul location, we look forward to strengthening our relationships in Korea and, in coordination with our Tokyo office, deepening our presence throughout the Asia Pacific region.”

“The opening of our Seoul office marks an important step in expanding our presence in Asia, and I’m honored to lead this effort alongside Andrew,” said Sangmyung Lee. “Establishing a local presence allows us to better serve our partners in Korea while continuing to grow our relationships across the Asia Pacific region.”
