Deal News | Mar 10, 2025 | PR Newswire Cision J.F. Lehman & Company

J.F. Lehman & Company, a prominent middle-market private equity firm with a focus on aerospace, defense, maritime, government, and environmental sectors, announced the sale of its portfolio company, Global Marine Group (GMG), to Keppel Infrastructure Fund. GMG, with a heritage dating back to 1850, is a major player in the subsea telecom maintenance and installation market. Headquartered in the United Kingdom, GMG provides essential services to maintain the integrity of global undersea communications networks. After acquiring GMG in 2020, JFLCO played an integral role in refocusing the business on its core telecom market, ultimately transforming the company into a premier independent provider of maintenance and installation services in the subsea sector. The support of JFLCO has been pivotal in this success story, helping to optimize operations and services, thereby securing the company's position as a leader in the industry. Evercore advised JFLCO on the transaction, with legal counsel from Jones Day and Blank Rome.
