10. Leases

Lessor

The Company rents microturbine equipment to customers under lease agreements with terms ranging from a few months to ninety-six months. The majority of our leases carry an initial term of thirty-six months and may include extension options, which are assessed at lease commencement to determine whether they are reasonably certain of exercise. Certain lease agreements provide the lessee with an option to purchase the underlying asset at the end of the lease term.

Monthly rental payments are fixed. Certain leases also include variable payment components for items such as fuel, excess labor, additional equipment, or technician labor and engineering support. Variable payments are not included in the measurement of the lease receivable and are recognized as revenue in the period earned.

Leases are classified at commencement as either sales-type leases or operating leases in accordance with ASC 842. In connection with its Energy-as-a-Service ("EaaS") business, the Company also enters into arrangements under which it rents certain microturbine equipment back from customers and subleases that equipment to end users, as further described in the Lessee section below.

Lessee

The Company leases facilities and equipment under various non-cancellable operating and finance leases with expiration dates through Fiscal 2037. All leases require the Company to pay maintenance, insurance, and property taxes. Lease agreements for the Company's primary office and manufacturing facilities include rent escalation provisions over the lease term and renewal options for successive five-year periods. Lease expense is recognized on a straight-line basis over the lease term, including any extension periods that are reasonably certain of exercise.

EaaS Sublease Arrangements

As part of its EaaS business, the Company rents used microturbine equipment from customers where that equipment would otherwise not be in use, and subleases that equipment to end users. During the three months ended June 30, 2026, the Company did not enter into any new rental agreements under this program and did not modify any existing agreements. The existing rental agreements provide the Company an option to extend the lease term; however, as exercise of these options is not considered reasonably certain, they are excluded from the determination of the lease term. There were no new rental agreements under this program during the three months ended June 30, 2025.

As of June 30, 2026, lease commitments totaled approximately 18 megawatts of microturbines and had an average term of 36 months and a total remaining commitment value of approximately $7.7 million.
