AAR Agrees to Buy 65% of Aircraft-Maintenance Firm MRO Holdings for $1.8 Billion
AAR will take a controlling stake in aircraft-maintenance provider MRO Holdings, subject to regulatory approval. The initial 65% interest carries about $1.8 billion of equity value, while AAR says the transaction implies a $4.0 billion enterprise value and includes separate debt repayment.
AAR has agreed to acquire a 65% controlling interest in MRO Holdings, expanding its aircraft maintenance business as airlines continue to lean on third-party repair capacity. Reuters and the Wall Street Journal report the initial stake at about $1.8 billion, and AAR's official announcement says the deal is expected to close in its fiscal third quarter ending February 2027, subject to regulatory approval and customary conditions.
The headline price needs accounting context. AAR describes the $1.8 billion as the equity value for the first 65% stake. It separately says MRO Holdings carries about $1.3 billion of borrowings that AAR expects to repay and that the transaction implies a $4.0 billion enterprise value. Those figures measure different parts of the deal and should not be treated as interchangeable.
The $1.8 billion is for the initial 65% stake
Reuters, the Wall Street Journal and AAR all describe the initial transaction as a 65% controlling acquisition. The $1.8 billion headline is the equity value assigned to that first stake.
AAR's release also gives a $4.0 billion implied enterprise value. Enterprise value includes capital-structure items beyond the equity being purchased, so it is not another way to state the same $1.8 billion figure.
AAR is using debt, stock and a PIPE to finance the transaction
AAR says it expects to use about $2.1 billion of new debt, approximately $780 million of AAR stock issued to existing MRO Holdings owners at $135 per share, and about $230 million of PIPE proceeds.
The company also expects to repay roughly $1.3 billion of MRO Holdings' existing borrowings. These funding and balance-sheet steps explain why the transaction financing is larger and more complex than the headline equity value alone.
AAR does not own the remaining 35% yet
After the initial closing, existing owners will retain 35% of MRO Holdings. AAR's release gives it rights to acquire that remainder over time rather than transferring it all at once.
The option structure includes 5% that can be exercised at any time within six years after the initial closing, plus three 10% tranches tied to the second, third and fourth anniversaries. Until those options are exercised and completed, the accurate ownership description is 65% control, not 100% ownership.
The strategic case is more maintenance capacity, but forecasts remain forecasts
Reuters says AAR is pursuing the deal as airline demand for maintenance remains strong amid supply-chain constraints and delayed aircraft deliveries. Aviation Week reports the combined maintenance footprint would increase materially, with more facilities and annual aircraft throughput moving toward roughly 3,000.
AAR also projects margin expansion and cost synergies after closing. Those are company forecasts, not completed outcomes. The next hard checkpoints are regulatory clearance, financing completion, the initial closing and then actual integration performance.
