Lone Star Closes Alliance Ground Buy, Ending 18-Month Saga

Lone Star Funds officially closed its acquisition of Alliance Ground International on March 26, bringing to an end an 18-month restructuring process that transformed the global airline ground handler from a debt-laden operator into a private equity-backed platform poised for consolidation.

The Dallas-based firm now holds full ownership of AGI, which provides ground handling, cargo, and passenger services to more than 100 airlines across 61 airports in North America, the Caribbean, Europe, and Asia. The deal marks one of the larger distressed aviation plays to close in 2026, though neither party disclosed the final purchase price.

What they did confirm: Lone Star will inject "significant capital" into modernizing AGI's fleet of ground support equipment, upgrading its technology infrastructure, and pursuing bolt-on acquisitions in fragmented markets where the company already has a footprint. Translation — this isn't a financial engineering play. It's a buy-and-build.

AGI emerged from Chapter 11 bankruptcy in September 2024 after shedding over $1 billion in funded debt and handing the keys to Lone Star, which provided the bulk of the debtor-in-possession financing and won a competitive auction for the restructured equity. The plan was approved. The regulatory filings dragged on for another 18 months as antitrust and foreign investment authorities in the U.S., U.K., and Japan scrutinized the transaction.

Alliance Ground wasn't always a restructuring candidate. The company was cobbled together through a series of acquisitions between 2012 and 2019, creating one of the largest independent ground handlers outside the airline-owned incumbents like Swissport and dnata. At its peak, AGI operated in over 70 airports with more than 20,000 employees.

Then COVID hit. Global air traffic collapsed, airlines renegotiated or walked away from handling contracts, and AGI's leverage — already high from acquisition debt — became unsustainable. The company laid off thousands, exited unprofitable stations, and tried to refinance. It didn't work. By mid-2024, AGI was hemorrhaging cash and facing maturity walls it couldn't meet.

Lone Star swooped in during the bankruptcy process with a stalking horse bid that effectively shut out other distressed investors. The firm agreed to provide $250 million in DIP financing, backstop an additional $150 million in exit financing, and take majority control of the reorganized company. No other bidder came close.

The bankruptcy court approved the plan in three months. The regulatory marathon that followed — coordinating antitrust reviews in multiple countries where AGI has operations — took five times longer. Lone Star declined to comment on which jurisdiction held up the process, but people familiar with the deal pointed to UK competition authorities, who requested additional commitments around service continuity at Heathrow and Gatwick before signing off.

Strip away the press release language, and AGI's asset base is straightforward: contracts with airlines, equipment fleets, and labor pools in 61 airports. The contracts are the real value. Ground handling is a sticky business — airlines don't switch providers often because the operational risk of a botched handoff is too high. AGI's customer roster includes United, Delta, American, British Airways, and Lufthansa, among others.

But the margins are brutal. Ground handling is a low-margin, labor-intensive business where profitability depends on density — the more flights you handle at a single station, the better you can amortize fixed costs like equipment and management overhead. AGI's problem pre-bankruptcy was that it operated in too many secondary airports where it handled too few flights to make money.

Lone Star's thesis, according to sources close to the deal, is that AGI exited bankruptcy as a leaner operator focused on high-density hubs. The firm now wants to grow through acquisition, buying smaller regional handlers in markets where AGI already has scale. The goal is to create the kind of density that drives pricing power and EBITDA margins north of 10% — a rarity in this sector.

Here's a snapshot of AGI's current footprint compared to its pre-bankruptcy peak and its major competitors:

AGI is smaller than the Big Three, but it's big enough to compete in major hubs and focused enough to avoid the over-diversification trap that plagued its pre-bankruptcy strategy.

One of the less-publicized parts of Lone Star's capital commitment is a fleet modernization push. AGI operates thousands of pieces of ground support equipment — baggage tractors, belt loaders, pushback tugs, deicing trucks — much of it aging diesel machinery purchased during the acquisition spree a decade ago. The company deferred maintenance during COVID, and the equipment shows it.

This isn't Lone Star's first rodeo in transportation and logistics. The firm has built and sold platform companies in everything from rail operations to last-mile delivery. The pattern is consistent: acquire a distressed or underperforming asset, recapitalize it, bolt on smaller competitors, drive operational improvements, and exit to a strategic buyer or take it public.

AGI fits that mold. The ground handling market is highly fragmented outside the top four players. Hundreds of regional and single-airport operators exist, many of them family-owned businesses that lack the capital to invest in the equipment and technology that airlines now demand. Lone Star can offer liquidity and integration into a national platform — a compelling pitch to owners looking for an exit.

The firm is already rumored to be in talks with at least two regional handlers in the southern U.S. and one in Western Europe, according to people familiar with the discussions. Names weren't disclosed, but the targets reportedly operate at airports where AGI already has a presence, allowing immediate cost synergies.

The risk, of course, is execution. Roll-up strategies work when the acquirer can integrate quickly, cut redundant costs, and cross-sell services. They fail when integration drags, key employees leave, or the platform becomes bloated. Ground handling has historically been a graveyard for roll-up attempts — Swissport itself has changed hands multiple times after failed consolidation efforts left it overleveraged.

Lone Star's advantage is that it's starting with a clean balance sheet. AGI emerged from bankruptcy with almost no funded debt and a cost structure reset to reflect post-COVID volume realities. That gives the company breathing room to pursue acquisitions without immediately loading up on leverage to fund them.

Not many. Typically, companies emerging from Chapter 11 are resource-constrained, focused on survival rather than growth. Lone Star structured the deal to avoid that trap. The firm provided the exit financing itself, meaning AGI doesn't owe interest payments to third-party lenders during its first few years of operation. That frees up cash flow to reinvest in the business rather than service debt.

It's a luxury afforded by deep-pocketed sponsors willing to play a long game. Lone Star has $85 billion in assets under management and a reputation for patient capital. The firm doesn't need a liquidity event in three years — it can wait five or seven if that's what it takes to build enterprise value.

The 18-month gap between bankruptcy exit and deal close wasn't normal. Most post-bankruptcy acquisitions finalize within 6-9 months once the plan is confirmed. Lone Star's wait was longer because AGI operates in jurisdictions where foreign ownership of aviation service providers triggers national security and competition reviews.

The UK's Competition and Markets Authority reportedly asked Lone Star to commit to maintaining service levels at London's two largest airports for at least three years — a condition designed to prevent the new owner from consolidating operations or reducing headcount in ways that could disrupt airline schedules. Lone Star agreed.

Japan's review focused on different concerns. AGI handles ground operations for several Japanese carriers at U.S. airports under bilateral aviation agreements. Japanese regulators wanted assurances that Lone Star wouldn't leverage that position to favor U.S. carriers in slot allocation or gate access — issues that touch on trade policy, not just competition.

These conditions matter because they constrain Lone Star's operational flexibility in key markets. The UK commitment, for instance, makes it harder to rationalize AGI's London workforce if flight volumes decline. The Japan approval limits how aggressively AGI can negotiate with non-Japanese airlines at the airports where it competes for business.

Maybe. Ground handling is invisible until it breaks, at which point it breaks spectacularly — flights delayed, bags lost, passengers stranded. Regulators view it as critical infrastructure, even though it's provided by private contractors. That explains why AGI's ownership change required approval from authorities who don't typically review mid-market PE deals.

It also signals something broader: governments are paying closer attention to who owns the companies that keep airports running. As aviation recovers from COVID, regulators don't want financial buyers prioritizing cost-cutting over service quality — especially in a sector where labor disputes and equipment failures can cascade into system-wide disruptions.

The press release says Lone Star will "invest in employees." That's vague enough to mean anything or nothing. What's clearer from the bankruptcy filings is that AGI cut its workforce by roughly 35% during the restructuring, shedding staff at unprofitable stations and consolidating management layers.

Lone Star isn't planning another round of cuts, according to people briefed on the integration plan. Instead, the firm is betting that volume growth — both organic and through acquisitions — will drive hiring. The company is already advertising for ramp supervisors, cargo handlers, and operations managers at several U.S. airports where flight activity has rebounded faster than expected.

But ground handling remains a tough job with high turnover. Workers are often part-time, hourly employees with few benefits and unpredictable schedules. Unionization rates vary widely by geography — high in Europe, lower in the U.S. — and labor disputes have historically been a drag on profitability in this sector.

Lone Star's capital plan includes wage increases tied to productivity metrics — essentially, pay workers more if they handle flights faster and with fewer errors. Whether that's enough to reduce turnover in a tight labor market remains to be seen.

The unions aren't sold. The International Association of Machinists and Aerospace Workers, which represents AGI employees at several U.S. airports, issued a statement saying it will "closely monitor" Lone Star's commitments and reserve the right to challenge any operational changes that affect working conditions.

Private equity firms don't buy companies to hold them indefinitely. Lone Star will want an exit, probably within five to seven years. The question is who the buyer will be — and whether the ground handling market has room for another big consolidation.

The most logical buyers are the existing Big Three: Swissport, dnata, and Menzies. All three have pursued roll-up strategies at various times, and all three could use AGI to plug geographic gaps or add density in overlapping markets. Swissport, in particular, has been rebuilding after its own financial troubles during COVID and might see AGI as a way to regain market share in North America, where it's weaker than in Europe.

Airlines themselves are another potential buyer category. Carriers like United and Delta have experimented with bringing ground handling in-house at their hub airports, arguing that vertical integration improves service quality and reduces delays. If AGI can prove that a well-run independent handler delivers comparable performance at lower cost, that thesis weakens. But if airlines decide they don't trust third parties with such critical operations, they might bid for AGI to acquire its contracts and infrastructure rather than let a competitor control it.

The wildcard is another financial buyer — a rival PE firm or a sovereign wealth fund looking for exposure to the aviation recovery. That buyer would likely pursue the same roll-up strategy Lone Star is executing, just with a longer time horizon. Sovereign funds from the Middle East and Asia have been active in aviation services, and AGI's international footprint could appeal to buyers looking to establish a platform outside their home markets.

Or Lone Star could take AGI public. The company is large enough to support a standalone listing, and the ground handling market is growing as air traffic recovers. An IPO would give Lone Star liquidity while leaving the door open to future M&A under AGI's own management. That route is riskier — public market investors tend to punish low-margin, capital-intensive businesses — but it's not off the table if Lone Star can demonstrate consistent EBITDA growth and margin expansion over the next few years.

Lone Star's acquisition of AGI is part of a broader trend: private equity firms betting that aviation service providers — not airlines themselves — are the better post-COVID investment. Airlines got the bailouts and the headlines, but their capital structures remain messy and their profitability cyclical. Companies that sell services to airlines, by contrast, often have more stable cash flows and less exposure to fuel prices and fare wars.

Ground handling, MRO (maintenance, repair, and overhaul), catering, and cargo handling have all seen PE interest spike since 2023. These businesses took a hit during COVID, but they recovered faster than the airlines because they didn't have to deal with fleet restructuring, route rationalization, or labor contract renegotiations on the same scale.

The catch is that these businesses are also more fragmented and harder to consolidate than they look. Swissport's struggles prove that just buying a bunch of ground handlers doesn't automatically create value — you have to integrate them, rationalize the footprint, and negotiate better rates with airline customers who have plenty of leverage.

Lone Star is betting it can do what others couldn't. The firm has the capital, the patience, and — now — a clean platform to build from. Whether AGI becomes a consolidation success story or another cautionary tale in aviation services will depend on execution over the next three to five years. The pieces are in place. The question is whether they fit together.
