Lone Star to acquire Alliance Ground International from PE owners.

Lone Star Funds has struck an agreement to acquire Alliance Ground International (AGI) from private equity owners Greenbriar Equity Group and Audax Private Equity, marking a notable consolidation move in airport operations. Financial terms were not disclosed; the deal is subject to customary closing conditions and regulatory approvals.

Founded in 1987 and based in Miami, AGI is a major provider of outsourced airport services in North America, operating at more than 60 airports and employing over 12,000 staff across cargo handling, passenger terminal support and ancillary on‑airport services. The business is positioned at the intersection of airline cost pressure and rising cargo volumes driven by e‑commerce, making scale and operational reliability critical competitive advantages.

Buyout firm Lone Star — acting through an affiliate of Lone Star Fund XII, L.P. — said it will back AGI’s management to invest across its core segments and to explore growth in existing and adjacent markets. Donald Quintin, Chief Executive Officer of Lone Star, commented on the strategic fit and the firm’s track record of investing in mission‑critical service platforms.

AGI’s chief executive, Jared Azcuy, highlighted the company’s safety and service credentials and signalled plans to pursue technological upgrades and process automation. For airport handlers, investments in digital baggage and cargo tracking, remote ops and automated ramp equipment can materially improve throughput and margins — trends that private owners often prioritise to boost long‑term value.

The transaction underscores a broader industry dynamic: third‑party ground handling is consolidating as airlines outsource more non‑core operations to specialist providers. Market estimates place the global ground‑handling and cargo services market in the tens of billions of dollars, growing at mid‑single digit compound annual rates as passenger travel recovers and air freight remains resilient. Scale matters: larger operators spread fixed costs across more flights and customers and can more readily absorb capital expenditure for automation.

Advisers on the deal include Evercore and BofA Securities on the financial side, with legal counsel provided by Vinson & Elkins and Ropes & Gray. These teams will help shepherd the closing process and any antitrust clearances across jurisdictions where AGI operates in the United States and Canada.

For Lone Star, the acquisition adds an asset that sits squarely in infrastructure‑adjacent services and offers operational levers for improvement — from route density optimisation and contract re‑negotiation to targeted capex in automation. For airports and carriers, a well‑capitalised handler can reduce turnaround times and improve cargo handling reliability, reinforcing supply‑chain resiliency.

Investors and industry watchers will be watching how Lone Star balances near‑term service continuity with investment to scale AGI’s footprint and capabilities. Given the centrality of ground operations to airport throughput and the structural tailwinds for air cargo, this transaction could catalyse further consolidation in North American ground handling.
