Ethereum-focused treasury firm ETHZilla is diversifying its asset portfolio in an unexpected direction by recently acquiring jet engines. A Friday filing with the U.S. Securities and Exchange Commission (SEC) disclosed that the company purchased two CFM56-7B24 aircraft engines for $12.2 million through a newly established subsidiary, ETHZilla Aerospace LLC.
Currently, these engines are leased to a major airline, and ETHZilla has engaged Aero Engine Solutions to manage them for a monthly fee. The agreement includes a buy-sell option, allowing either party to require the other to buy or sell the engines for $3 million each when the lease expires, contingent on the engines remaining in proper condition.
At first glance, this move may appear unconventional for a company typically associated with cryptocurrency. However, acquiring and leasing aircraft engines is a standard practice in the aerospace sector. Airlines often lease spare engines to ensure operational continuity, mitigating the risk of potential disruptions caused by primary engine failures. Notable companies in this sector include AerCap, Willis Lease Finance Corporation, and SMBC Aero Engine Lease.
The aerospace industry is currently grappling with a significant supply squeeze for large engines. The International Air Transport Association (IATA) estimates that airline members could be forced to spend about $2.6 billion leasing additional spare engines by 2025. In fact, forecasts predict that the global aircraft engine leasing market will expand from $11.17 billion in 2025 to $15.56 billion by 2031, reflecting a compound annual growth rate (CAGR) of 5.68%, as reported by TechSci Research.
This strategic pivot comes at a time when digital asset treasuries are under increasing pressure due to the recent downturn in cryptocurrency markets. Many public entities that aggressively raised capital to stockpile tokens last year are now seeing their holdings trade significantly below their net asset values (NAV), limiting options for raising new capital. ETHZilla itself sold $40 million in Ethereum in October as part of a stock buyback program and offloaded an additional $74.5 million in December to address outstanding debt. The company’s stock has plummeted roughly 97% since its peak in August.
Despite the tumultuous state of the crypto market, the acquisition of aircraft engines may align with ETHZilla’s broader goals of bringing tokenized real-world assets (RWAs) onto the blockchain. In a December shareholder letter, the firm proposed plans to tokenize various assets alongside Liquidity.io, a regulated broker-dealer and SEC-registered alternative trading system (ATS). Prior to this, ETHZilla took a 15% stake in Zippy, a lender specializing in manufactured home loans, with the intention of tokenizing those loans as compliant, tradable instruments. Additionally, the firm acquired a stake in the auto finance platform Karus, aiming to transition loans onto the blockchain.
In a recent post on X, the firm emphasized its commitment to creating a scalable tokenization pipeline across asset classes characterized by predictable cash flows and global investor demand. ETHZilla anticipates launching its first tokenized asset offerings in the first quarter of the year, signifying a forward-looking approach to navigating the challenges posed by the current crypto landscape.
