Shares of AAR Corp (AIR) soared 5.18% on Thursday following the company's impressive fourth-quarter earnings report and optimistic guidance for the upcoming fiscal year. The aviation services provider delivered results that surpassed analyst expectations, demonstrating robust growth across its key business segments.

AAR reported adjusted earnings per share of $1.16 for the quarter, handily beating the consensus estimate of $1.01.

Looking ahead, AAR's management expressed confidence in continued growth. The company expects organic sales growth in fiscal year 2026 to approach 9%, building on the momentum from fiscal 2025.

The company announced a major win with Delta Airlines, which is expected to significantly boost Trax's revenue over the coming years. Additionally, AAR's strong balance sheet and reduced leverage position it well for future growth opportunities and potential acquisitions.
