AAR CORP 8-K

What Happened
AAR CORP. (AIR) announced on May 6, 2026 that its chief operating decision maker implemented a reorganization of the company’s operating segments during the fourth quarter of fiscal 2026 and that the company will wind down its Commercial Programs business. Beginning in Q4 FY2026 (and reflected in the Form 10‑K for the year ending May 31, 2026), AAR will report under four new segments: Parts Supply; Repair, Engineering, and Software; Government Solutions; and Legacy Commercial Programs. The company also repositioned its software platform (including Trax and Airinmar) into Repair, Engineering, and Software, and combined Government Programs with its Mobility/Expeditionary Services activities into Government Solutions.

Key Details

• Date filed: May 6, 2026; changes implemented in Q4 of fiscal 2026.
• New segments: Parts Supply; Repair, Engineering, and Software; Government Solutions; Legacy Commercial Programs.
• Software relocation: Trax and Airinmar moved into the renamed Repair, Engineering, and Software segment.
• The filing furnishes recast historical unaudited segment financial information (FY2024, FY2025 and selected quarters in FY2025–FY2026) consistent with the new segment structure; it includes non‑GAAP measures (adjusted sales, adjusted operating income, adjusted EBITDA, margins).

Why It Matters
The reorganization changes how AAR will present revenue and operating results by business line, giving investors clearer visibility into parts distribution, MRO and software, government work, and the legacy commercial service programs. The wind-down of Commercial Programs could alter the company’s future revenue mix and quarterly results, but the filing states these presentation changes do not amend previously reported consolidated financial statements, totals, or prior GAAP results. Investors should watch upcoming quarterly reports and the FY2026 Form 10‑K for the recast segment disclosures and to assess how the new structure affects revenue and operating margins.
