ABX Air
ABX Air operates as the primary cargo airline within the Air Transport Services Group (ATSG) structure, now under the ownership of infrastructure investor Stonepeak following a 2025 acquisition. The corporate entity runs a fleet of Boeing 767-200 and 767-300 converted freighters out of its hub at Wilmington Air Park in Ohio. Its principal contracts include ACMI service agreements with DHL Network Operations and aircraft leasing to Amazon.com Services, alongside charter work for the U.S. Transportation Command. The firm directs a corporate investment portfolio sized at $890 million (Altss estimate), with a target allocation of 50% equity, 45% fixed income, and 5% real estate. Hard assets under its umbrella include the Wilmington Air Park sorting facility and commercial property holdings in King County, Washington, valued at $5.77 million. The company also controls two wholly-owned operating subsidiaries — Airborne FTZ, Inc., a logistics entity, and ABX Material Services, Inc., an aviation support business — and holds a co-investor stake in LGSTX Services, Inc. alongside ATSG. ABX Air holds memberships in Airlines for America and the International Air Transport Association, and has engaged Goldman Sachs, Evercore, and Davis Polk for financial and legal advisory work since 2024. In a notable community-facing move, its affiliated ATSG Charitable Foundation provided an estimated $560,000 in giving, directing donations to the Ohio 4-H Foundation, United Way, American Red Cross, and Wounded Warrior Project. The firm also sponsored Girls in Aviation Day 2025 in Wilmington, OH. Structurally, ABX Air is a corporate operated investment pool embedded in a transport infrastructure portfolio rather than a traditional family office or pension fund. The 2025 Stonepeak take-private of ATSG places the entire enterprise — fleets, real estate, operating companies, and the investment book — inside an institutional infrastructure fund, shifting its governance from a publicly traded agglomeration to a privately held, long-duration asset manager.

Frequently asked questions
Who owns ABX Air, Inc.?
ABX Air is an operating subsidiary of Air Transport Services Group, Inc. (ATSG).

What is the composition of ABX Air's investment portfolio?
The corporate investment portfolio is approximately $890 million (Altss estimate). Its target allocation comprises 50% public equities, 45% fixed-income instruments, and a 5% allocation to real estate, supplemented by direct holdings in industrial aviation assets and commercial property in King County, Washington.
What hard assets does ABX Air own?
The company's tangible asset base includes a fleet of Boeing 767-200 and 767-300 converted freighters operating from the Wilmington Air Park hub. It also owns the Wilmington Air Park sorting facility in Ohio and $5.77 million in commercial real property in King County, Washington. Its subsidiary, ABX Material Services, Inc., further supports aviation-related operations.
How does ABX Air generate its operating revenue?
ABX Air provides ACMI (Aircraft, Crew, Maintenance, and Insurance) services primarily to DHL Network Operations under long-term contracts. It also leases aircraft to Amazon.com Services and operates charter flights for the U.S. Transportation Command. The investment portfolio is a distinct function from these operating businesses.
Does ABX Air maintain a philanthropic vehicle?
Yes, the ATSG Charitable Foundation serves as a 501(c)(3) entity tied to the broader group. It directs giving toward STEM education, community wellness, and veterans' programs, with notable donations to the Ohio 4-H Foundation, United Way, and the Wounded Warrior Project. Estimated giving is approximately $560,000 (Altss estimate).
Is ABX Air structured as a family office or an institutional fund?
It is neither. ABX Air is a corporate asset owner. Its investment pool operates within a cargo airline subsidiary, applying a pension-fund-like allocation strategy to corporate treasury assets under an institutional infrastructure owner. There is no family wealth origin or open LP base.
Who are ABX Air's primary financial advisors?
Since 2024, Goldman Sachs and Evercore have served as financial advisors for the parent group, with legal counsel provided by Davis Polk & Wardwell and Vorys, Sater, Seymour and Pease. These relationships coincide with the Stonepeak acquisition and governance restructuring.
