Lone Star Funds announced it will acquire Alliance Ground International, a leading North‑American airport services provider, from Greenbriar Equity Group and Audax Private Equity. The transaction, routed through an affiliate of Lone Star Fund XII, closes a private‑equity hand‑off for a platform that operates at more than 60 U.S. and Canadian airports.

Founded in 1987 and based in Miami, AGI employs over 12,000 professionals delivering cargo handling, passenger terminal and ground handling services that keep airline schedules and global trade flowing. Lone Star’s CEO Donald Quintin said the firm will partner with management to pursue new service segments and geographic expansion.

AGI chief executive Jared Azcuy called the deal a “new phase” that will accelerate technology adoption and global reach. Evercore advises Lone Star, while BofA Securities and Ropes & Gray counsel AGI. Closing hinges on standard regulatory approvals, and investors will watch how the infusion of capital fuels consolidation across the fragmented airport‑services market.
