Mammoth Energy Services has secured a $58 million senior secured aviation term loan facility from Bank7 to support the continued expansion of the company’s aviation leasing platform.
Mammoth subsidiaries Cobra Aviation Services and Leopard Aviation entered into the loan and security agreement on October 28, 2026.
The financing provides for up to $58 million of senior secured term loans that Mammoth expects to use to acquire additional aviation assets.
The facility consists of a $25 million Term Loan A and a $33 million Term Loan B.
Each loan may be drawn during the 60-day period following the transaction’s closing, although advances under Term Loan B remain subject to certain conditions.
The loans carry floating interest rates and will begin amortizing monthly in January 2027.
Both term loans mature in October 2030.
The facility is secured by aviation assets owned by the borrowers and is guaranteed by Mammoth Energy Services. The company did not draw any amounts from the facility at closing.
As of September 30, 2026, Mammoth said the total cost of its aviation portfolio was approximately $134.9 million.
That portfolio had been funded without debt, giving the company an opportunity to introduce asset-backed financing as it expands its fleet.
Mammoth sees the new facility as a way to add what it views as prudent leverage while maintaining liquidity for other corporate priorities.
The company has increasingly centered its growth strategy around aviation leasing.
Through its rental services segment, Mammoth leases and sells aviation assets while also renting heavy equipment used in construction and energy operations.
Its other businesses include fiber-optic services for utilities, natural sand proppant used in hydraulic fracturing, workforce accommodations for remote projects, and directional drilling services.
The Bank7 financing gives Mammoth additional capital capacity to continue purchasing aviation assets as it expands that part of its portfolio.
KEY QUOTES:
“This facility is an important step for our aviation platform.”
“This facility allows us to add prudent leverage and fund the next phase of fleet growth while preserving liquidity.”
Mark Layton, Chief Financial Officer Of Mammoth Energy Services
