AAR Corp. (AIR) is down 5.8% today. Here is some analysis on what might have caused this price movement.

Analysis: The sell-off appears tied less to AAR’s quarterly operating performance and more to investor reaction to its large MRO Holdings deal and the financing attached to it. AAR posted strong fiscal first-quarter results and modestly improved its full-year sales outlook, but the acquisition introduces higher leverage, new share issuance, and execution risk that may be weighing on the stock.

Details:

AAR announced an agreement to acquire a 65% controlling interest in MRO Holdings at an implied enterprise value of about $4.0 billion, a transaction large enough to reshape the company’s balance sheet and strategy.

The company also reported a strong start to fiscal 2027, with first-quarter sales of $918 million, adjusted diluted EPS of $1.49, and adjusted EBITDA up 34% from a year earlier.

The financing plan includes new debt plus equity issuance, including roughly $780 million of stock to current MRO Holdings owners and an additional PIPE equity raise of about $230 million.

AAR said net leverage is expected to rise to about 3.6x at closing before falling over time, which suggests the market may be focusing on dilution and integration risk despite the strategic upside.
