Key financial metrics and changes
- Sales rose 24.1% year over year. Commercial sales increased 28.2% to $670.8; government and defense sales increased 14.3% to $247.2. Management cited strong demand and volume, acquisitions, and growth in new-parts distribution.
- Gross profit grew 31.9%, and consolidated gross margin expanded 1.1 percentage points. Operating income increased 11.1%, but operating margin declined from 8.8% to 7.9%, as SG&A grew 49.0% to $107.0 (11.7% of sales versus 9.7%). The company attributed much of the SG&A increase to $22.0 of acquisition-related incremental expenses.
- Segment performance was mixed: Parts Supply sales rose 30.5% and operating income rose 35.2%; Repair, Engineering, and Software sales rose 31.4%, but operating income fell 20.0% to $16.0 and margin declined to 5.4% from 8.8%; Government Solutions operating income rose 50.4%; Legacy Commercial Programs operating income was $2.9 versus $0.4.
- Operating cash flow improved by $100.7 year over year, from a cash use to cash generation. Working-capital movements included a $50.5 increase in receivables and a $41.1 increase in inventory, partly offset by higher payables and a $27.5 decrease in rotable assets. Investing used $25.6; financing used $24.9. Capital expenditures were $11.8.
- At August 31, cash was $104.5, restricted cash $8.6, working capital $1,189.1, and total debt $879.6 (including $700.0 of senior notes and $185.0 drawn on the revolver). Revolver availability was $632.3 after letters of credit. The company reported covenant compliance and said available liquidity should cover requirements for at least the next 12 months.
- Debt declined from $893.9 at May 31; interest expense fell to $16.6 from $18.8. The average revolver borrowing rate was 5.34%, versus 6.14% a year earlier. The $700.0 senior notes bear 6.75% interest and mature in 2029.
Outlook, material developments, and risks
- Firm backlog was approximately $866, with about 70% expected to be recognized as revenue over the next 12 months and a further 15% in the following 12 months. The filing provides no specific full-year financial guidance.
- On September 28, 2026, after quarter-end, AAR agreed to acquire a 65% controlling interest in MRO Holdings for approximately $3.0 billion, including repayment of $1.3 billion of the target’s existing borrowings. Expected funding includes approximately $2.1 billion of new debt, $780 of AAR equity issued to sellers, and $230 of PIPE proceeds. Closing is expected in Q3 FY2027, subject to conditions including regulatory approvals. AAR has options to acquire the remaining 35%. The company incurred $7.3 of transaction costs in the quarter. Completion, financing, integration, and realization of anticipated benefits are material risks.
- AAR plans to exit Legacy Commercial Programs over approximately three to four years, terminating or exiting contracts and selling rotable assets. It stopped depreciating the related rotable pool as of June 1, 2026; future impairment of the segment’s $16.4 goodwill is expected as the wind-down progresses. Rotable asset sales were $29.0 in the quarter, versus $6.5 a year earlier.
- Repair, Engineering, and Software results included $4.9 of Trax contingent-consideration compensation expense. AAR recorded a $13.0 liability; former Trax owners are contesting the determination in arbitration, which the company expects to finalize in fiscal 2027. AAR states it disputes the claims.
- Other notable items include unfavorable $3.4 cumulative catch-up adjustments on long-term programs and $3.5 of HAECO Americas integration expenses. AAR also disclosed an uncapped performance guarantee claim for which the customer seeks at least $32 in damages; a loss is reasonably possible, but the company cannot estimate a loss range.
- Other contingencies include a $2.1 long-term liability, including interest, for a Russian judgment, and a $0.9 accrued fine related to Nepalese proceedings. AAR says it has defenses to the Russian matter and does not intend to pay the Nepalese fine, disputing the process.
- Management cited aviation-industry and government-demand exposure, fixed-price contract cost overruns, labor and supplier constraints, acquisition and integration execution, debt and capital-market access, regulatory compliance, cybersecurity, and product-liability exposure among the risks that could affect results.
