FISCAL YEAR 2025 HIGHLIGHTS

(As compared to FY2024)

“In Fiscal Year 2025, we delivered record sales and profitability and made meaningful progress against our strategic objectives,” said John M. Holmes, AAR’s Chairman, President and Chief Executive Officer. “We substantially completed the integration of the Product Support acquisition and continued to optimize our portfolio with the divestiture of our Landing Gear Overhaul business. We further invested in our fast growing new parts Distribution activities, launched two hangar expansions, and announced several key new business wins for our Trax software solution. We continued to reduce our net leverage, ending the fiscal year at 2.72x. Our optimized portfolio, combined with our strengthened balance sheet, is delivering higher growth, higher margins, and stronger returns.”

Holmes continued, “Our fiscal fourth quarter was an extremely strong finish to a record year. We delivered double-digit sales and earnings growth over the prior year quarter. Adjusted sales were up 12% organically due to strong demand across both our commercial and government end-markets. Our new parts Distribution activities continue to lead with an over 20% organic increase in sales driven by both market growth and market share gains. Our Adjusted EBITDA growth of 19% during the quarter reflects continued margin improvement, expanding 80 basis points year-over-year to 12.4%. We see additional opportunities for further margin improvement from sales mix, synergy realization, and other efficiency initiatives.”

FOURTH QUARTER FISCAL YEAR 2025 RESULTS

Consolidated fourth quarter sales increased 15% to $754.5 million, compared to $656.5 million in the same quarter last year. Sales in the fourth quarter of fiscal year 2025 included the sale of certain rotable assets to a significant regional airline customer for $18.7 million in conjunction with the termination of a power-by-the-hour program, which has been excluded from our adjusted sales. Consolidated sales to commercial customers increased 12%, or $56.5 million, primarily due to strong demand for new parts Distribution activities and the rotable asset sale. Sales to government customers increased 21% from the same period last year, primarily due to increased order volume for new parts Distribution activities and double-digit growth in our Integrated Solutions segment. Sales to commercial customers were 69% of consolidated sales, compared to 70% in the prior year quarter.

The Company reported net income of $34.0 million, or $0.95 per share. For the fourth quarter of the prior year, the Company reported net income of $9.1 million, or $0.26 per diluted share. Adjusted diluted earnings per share in the fourth quarter of fiscal year 2025 were $1.16, compared to $0.88 in the fourth quarter of the prior year.

Selling, general, and administrative expenses were $77.4 million in the current quarter, compared to $94.8 million in the prior year quarter. Acquisition, amortization, and integration expenses were $0.3 million in the quarter, compared to $17.1 million in the prior year quarter primarily due to the closing of the Product Support acquisition in the prior year quarter.

Operating margins were 9.7% in the quarter, compared to 5.0% in the prior year quarter. Adjusted operating margin increased to 10.5% in the current year quarter from 9.3% in the prior year quarter, primarily as a result of strong growth and favorable mix in Parts Supply. Sequentially, our adjusted operating margin increased from 9.7% to 10.5%, also driven by the profitability in Parts Supply.

Net interest expense for the quarter was $18.4 million, compared to $18.7 million last year. Average diluted share count increased from 35.4 million shares in the prior year quarter to 35.6 million shares in the current year quarter. We repurchased 0.2 million shares for $10.1 million during the quarter and have $42.5 million remaining on our share repurchase program.

Cash flow provided by operating activities was $51.4 million during the current quarter, compared to $24.5 million in the prior year quarter. Excluding the accounts receivable financing program, cash flow provided by operating activities was $50.3 million in the current quarter. As of May 31, 2025, net debt was $880.5 million and net leverage was 2.72x.

Holmes continued, “We are pleased to finish the year with a strong quarter of cash flow generation. We have delivered on our commitment to reduce leverage following the Product Support acquisition. Since the acquisition, our net leverage has decreased from 3.58x to 2.72x. Our financial position is strong and we have a solid foundation for continued capital allocation to drive growth.”

FISCAL YEAR 2025 RESULTS

Full fiscal year 2025 consolidated sales were $2.8 billion, an increase of 20% over fiscal year 2024 with growth resulting from our Product Support acquisition and increased volumes in our new parts distribution activities.

Operating margins were 6.7% for the full year, compared to 5.6% in fiscal year 2024. Adjusted operating margin increased to 9.6% in fiscal year 2025 from 8.3% in fiscal year 2024. The improved adjusted margins are primarily driven by the favorable contribution from the Product Support business and growth in Parts Supply.

Full fiscal year 2025 net income was $12.5 million, or $0.35 per diluted share. Fiscal year 2025 results included after-tax charges of $115.0 million associated with the sale of our Landing Gear Overhaul business and our FCPA settlement and related costs. In fiscal year 2024, net income was $46.3 million, or $1.29 per share. Our adjusted diluted earnings per share was $3.91 in the current year, compared to $3.33 last year, reflecting the impact of our improved operating efficiency on higher sales volumes.

Sales to commercial customers were 71% of consolidated sales in both the current and prior year. Cash flow provided by operating activities was $36.1 million in fiscal year 2025. Excluding our accounts receivable financing program, our cash flow provided by operating activities was $28.5 million in fiscal year 2025.

Holmes concluded, “As we enter our fiscal year 2026, we are excited about the opportunities ahead of us. We expect to continue to gain market share in Parts Supply and expand both our capabilities and footprint in Repair & Engineering. We expect Trax to continue its growth trajectory as we win more business and upgrade existing Trax customers to our latest offerings. Additionally, we remain focused on converting our large pipeline of government opportunities to new business wins. We are well-positioned within our markets and expect to drive further growth and margin expansion in our fiscal 2026.”

Adjusted net income, adjusted diluted earnings per share, adjusted operating margin, adjusted cash flow provided by operating activities, adjusted EBITDA, adjusted EBITDA margin, net debt, and net debt to adjusted EBITDA (net leverage) are “non-GAAP financial measures” as defined in Regulation G of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We believe these non-GAAP financial measures are relevant and useful for investors as they illustrate our core operating performance, cash flows, and leverage unaffected by the impact of certain items that management does not believe are indicative of our ongoing and core operating activities. When reviewed in conjunction with our GAAP results and the accompanying reconciliations, we believe these non-GAAP financial measures provide additional information that is useful to gain an understanding of the factors and trends affecting our business and provide a means by which to compare our operating performance and leverage against that of other companies in the industries we compete. These non-GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.

Our non-GAAP financial measures reflect adjustments for certain items including, but not limited to, the following:

Adjusted EBITDA is net income before interest income (expense), other income (expense), income taxes, depreciation and amortization, stock-based compensation, and items of an unusual nature including but not limited to business divestitures and acquisitions, FCPA investigation, settlement and remediation compliance costs, pension settlement charges, certain legal judgments, acquisition, integration, and amortization expenses from recent acquisition activity, and significant customer contract terminations.

Pursuant to the requirements of Regulation G of the Exchange Act, we are providing the following tables that reconcile the above-mentioned non-GAAP financial measures to the most directly comparable GAAP financial measures:

We believe these non - GAAP financial measures are relevant and useful for investors as they illustrate our actual operating performance unaffected by the impact of certain items . When reviewed in conjunction with our GAAP results and the accompanying reconciliations, we believe these non - GAAP financial measures provide additional information that is useful to gain an understanding of the factors and trends affecting our business and provide a means by which to compare our operating performance against that of other companies in the industries we compete . These non - GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP . Adjusted EBITDA is net income (loss) before interest income (expense), other income (expense), income taxes, depreciation and amortization, stock - based compensation, and items of an unusual nature including but not limited to business divestitures and acquisitions, workforce actions, COVID - related subsidies and costs, impairment and exit charges, facility consolidation and repositioning costs, FCPA investigation settlement and related costs, equity investment gains and losses, pension settlement charges, legal judgments, acquisition, integration and amortization expenses from recent acquisition activity, and significant customer events such as early terminations, contract restructurings, forward loss provisions, and bankruptcies . Adjusted operating income is adjusted EBITDA gross of depreciation and amortization and stock - based compensation . Pursuant to the requirements of Regulation G of the Exchange Act, we provide tables that reconcile the above - mentioned non - GAAP financial measures to the most directly comparable GAAP financial measures in the Appendix at the end of this presentation . The Company is not providing a reconciliation of forward - looking adjusted operating margin to the most directly comparable forward - looking GAAP measure because the information is not available without unreasonable effort . This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as, but not limited to, unusual gains and losses, the ultimate outcome of pending litigation, the impact and timing of potential acquisitions and divestitures, and other structural changes or their probable significance . Each of the adjustments has not occurred, are out of the Company's control and/or cannot be reasonably predicted . For this reason, the Company is unable to address the probable significance of the unavailable information . 14
