Summary
Aviation services company AAR Corp. has agreed to acquire a 65% controlling interest in MRO Holdings, a Bain Capital-backed aircraft maintenance provider, for approximately $1.8 billion. The transaction includes a six-year option for AAR to acquire the remaining 35% stake from existing minority investors. According to the Wall Street Journal, AAR will fund the deal partly through the issuance of approximately $780 million in AAR stock to MRO's shareholders, allowing Bain Capital, the Kriete family (founders), and Caoba Capital to retain economic exposure to the business through their continued AAR shareholdings.
MRO Holdings, headquartered in Wood Dale, Illinois, operates a geographically diversified platform of aircraft maintenance and modification facilities across the United States, Mexico, El Salvador, and Colombia. The company generates approximately 90% of its revenue from US-based customers, primarily commercial airlines. Bain Capital acquired its initial stake in MRO Holdings in 2024 as a minority investor alongside the founder's family and Caoba Capital.
The acquisition serves multiple strategic objectives for AAR, which was founded in 1955 and operates across aircraft parts distribution as well as maintenance, repair, and overhaul services. The transaction will expand AAR's maintenance capacity and geographic reach while positioning the company to capture incremental demand from the growing aviation services market. Management expects the MRO integration to materially improve profitability, with Ebitda margins projected to reach 19-20% within three to four years following deal completion, compared with AAR's current margin range of 13-14%.
AAR's equity performance has been robust over the trailing twelve months, with shares appreciating approximately 30%, driven in part by strengthened demand for aircraft parts distribution. The MRO Holdings acquisition represents a significant capital deployment that management believes will further enhance shareholder returns through margin expansion and operational leverage in the growing MRO services market.
