AAR (AIR) concentration risks

AAR Corp.'s sole disclosed concentration is a customer exposure: sales to branches, agencies, and departments of the U.S. government and their contractors totaled $687.6 million, representing 24.7% of consolidated sales in fiscal 2025. By disclosed size this is a small share at the individual-buyer level, but the U.S. government functions as a single procurement ecosystem whose policies, budgets, and contracting decisions move together. The character of this exposure is mixed — it combines the structural stability of a large, creditworthy customer base with the idiosyncratic risk of policy-driven spending changes, budget continuing resolutions, or program cancellations that can affect near-term order flow. Because this is the only disclosed concentration, there are no overlapping product, geographic, or supplier exposures layered on top. The rest of the revenue base is by implication derived from commercial customers, which provides some diversification against a decline in government spending, though the filing does not quantify that offset. On balance this is a limited-share exposure that is well-disclosed and relatively well-understood. The main risk channel is not single-contract dependency but rather aggregate government budget cycles and policy shifts that affect the volume and pace of maintenance, repair, and operations spending. Monitoring defense and government services budgets is the most relevant variable for this portion of the business.
