Stonepeak Finalizes $3.1B Acquisition of ATSG in All-Cash Deal

Stonepeak, a U.S.-based investment firm, has completed its acquisition of Air Transport Services Group (ATSG), the parent company of ABX Air, Air Transport International (ATI), and Omni Air International. The all-cash transaction, first announced in November 2024, values ATSG at approximately USD3.1 billion.
ATSG shareholders approved the deal on February 10, 2025. As a result, ATSG’s common shares have been delisted from the Nasdaq, with shareholders receiving USD22.50 per share in cash—representing a nearly 30% premium over the pre-announcement stock price.
Following the acquisition, ATSG will operate as a wholly owned subsidiary of Stonepeak, maintaining its current branding and structure. The company reported nearly USD2 billion in revenue and a net profit of USD27.4 million in 2024. At year-end, ATSG had a fleet of 167 aircraft, including 147 freighters and 20 passenger aircraft.
In addition to its three cargo airlines, ATSG owns several aviation support businesses, including Cargo Aircraft Management, Airborne Global Solutions, Airborne Training Services, Airborne Maintenance & Engineering Services, and PEMCO Conversions.
According to the ch-aviation fleets module, ABX Air operates 36 aircraft, primarily Boeing 767 freighters. ATI manages a fleet of 50 aircraft, including Boeing 757s and 767s. Omni Air International operates 14 widebody passenger aircraft, including Boeing 767 and 777 models.
The acquisition strengthens Stonepeak’s presence in the air cargo and aviation services sector, positioning it to capitalize on continued growth in e-commerce and global freight demand.
