AAR (AIR) Stock Forecast & Price Target

AAR is well positioned by durable demand in commercial aftermarket parts and MRO, with 4Q26 organic adjusted sales up 13% and Parts Supply organic growth of 19% driven by new distribution agreements, while Repair, Engineering and Software grew 35% on higher component and airframe throughput plus Trax recurring revenue. Its fiscal 1Q27 guide for 21–23% total sales growth and 12.25–12.75% adjusted EBITDA margins, excluding Legacy Commercial Programs, suggests strong core execution, though a roughly 50 bps LCP headwind tempers reported margins. The balance sheet and cash generation also support the thesis, as net debt fell to $816M with leverage at 2.0x and adjusted operating cash conversion reached 24% of adjusted EBITDA, leaving room for continued deleveraging and margin expansion.

AAR is facing a fundamentally fragile outlook because its growth depends on a modest 10% top-line expansion through 2028 while adj. EBITDA would still only reach about $420M, implying limited operating leverage if commercial aviation recovers slowly or government demand weakens. The company is also prioritizing working capital and inventory investment over free cash flow, with FY24 FCF of just $14M and FY25 FCF of $1M, leaving investors exposed to weak cash conversion even as capital is directed toward growth, de-leveraging, and M&A. On top of that, a $70M annual revenue headwind from the April 2025 OMB proposal, the expected 3-4 year wind-down of Legacy Commercial Programs, and litigation or contract risks reinforce the view that margins and earnings visibility are under pressure.
