Aergo Capital Acquires WestJet-Leased Boeing 737 MAX 8 from Aircastle

Dublin-based aircraft leasing and asset management platform Aergo Capital has announced the acquisition of one Boeing 737 MAX 8 aircraft from Aircastle. The transaction, announced on December 16, 2025, involves an aircraft bearing Manufacturer Serial Number (MSN) 60513, which is currently on lease to Canadian carrier WestJet.

This acquisition marks a continuation of Aergo Capital’s strategy to invest in modern, fuel-efficient narrowbody aircraft. According to the company’s official statement, the deal underscores the active secondary market for the 737 MAX and strengthens the trading relationship between the two major lessors. The aircraft remains in operation with WestJet, ensuring continuity for the airline while transferring asset ownership to Aergo.

The deal highlights the growing collaboration between Aergo Capital and WestJet, following significant transactions earlier in the operational year. By acquiring this asset, Aergo expands its portfolio of liquid, in-demand aviation assets while Aircastle executes its strategy of active portfolio management.

Transaction Overview and Executive Commentary

The specific asset involved in the transaction is a Boeing 737 MAX 8, identified by MSN 60513. Fleet data indicates this aircraft operates under the registration C-GRAX. Originally delivered during the initial rollout phase of the MAX program, the aircraft is approximately eight years old and represents the current generation of Boeing’s narrowbody technology.

Fred Browne, Chief Executive Officer of Aergo Capital, emphasized the importance of the acquisition in strengthening ties with both the seller and the lessee. In a statement regarding the deal, Browne noted:

“We are pleased to complete the acquisition of this Boeing 737 MAX 8 from Aircastle… I also extend my thanks to WestJet for their continued partnership and support.”

On the seller’s side, Aircastle, a Stamford-based lessor owned by Marubeni Corporation and Mizuho Leasing, viewed the sale as a testament to their strong commercial network. Michael Inglese, CEO of Aircastle, commented on the relationship between the firms:

“We value the long-standing trading relationship we have built with Aergo… The acquisition underscores the strong commercial relationship between Aergo and Aircastle.”

Strategic Context and WestJet Partnership

Deepening Ties with WestJet

This transaction is not an isolated event but rather part of a deepening relationship between Aergo Capital and WestJet. In August 2024, Aergo completed a significant sale-and-leaseback transaction involving eight Boeing 737-800 aircraft with the Canadian airline. That deal marked the first major collaboration between the two entities. The addition of this 737 MAX 8 further cements Aergo’s position as a key partner in WestJet’s fleet financing structure.

Asset Liquidity and Market Demand

For Aircastle, the sale aligns with a strategy of capital recycling and portfolio optimization. Trading assets with leases attached is a common practice in the aircraft leasing industry, allowing lessors to manage age profiles and risk exposure. For WestJet, the transaction represents a “backend” change of lessor; the airline retains physical possession and operational control of the aircraft, merely redirecting lease payments to the new owner, Aergo Capital.

AirPro News Analysis

The Secondary Market for the MAX 8

The transfer of a Boeing 737 MAX 8 between two major lessors highlights the intense demand for this asset class in the secondary market. With new aircraft production facing documented delays across the industry, “on-lease” assets, aircraft that are already built, certified, and generating revenue, have become premium commodities.

While an eight-year-old airframe might typically be considered approaching mid-life, the 737 MAX 8 remains a current-generation asset offering approximately 14% better fuel efficiency than its predecessors. For lessors like Aergo Capital, acquiring such an asset avoids the long wait times associated with factory order books. For the industry at large, this trade signals that liquidity for the MAX platform remains robust, despite, or perhaps because of, supply chain constraints limiting the delivery of new metal.
