OPERATING LEASES
The Company’s operating leases consist primarily of corporate office space, warehouses, and equipment used in its operations; the Company’s finance leases are not material.
Lease terms on the Company’s operating leases range from approximately one month to eight years. The majority of these leases require fixed monthly lease payments that may be subject to annual increases throughout the lease term. The Company’s lease agreements do not contain material residual value guarantees or restrictive covenants. Certain leases include renewal options at the election of the Company to extend the lease for an additional one to five years. As of December 31, 2025, the Company was not reasonably certain of exercising any material purchase, renewal, or termination options contained within its lease agreements. No ROU asset impairment charges were recorded during the years ended December 31, 2025, 2024 and 2023.
The Company determined that the DoW Offtake Agreement contains an embedded lease of the 10X Facility as a result of the DoW’s (i) right to obtain substantially all of the economic benefits of the 10X Facility and (ii) ability to direct the use of the 10X Facility for magnet production. See Note 3, “Public-Private Partnership with U.S. Department of War,” for more information about the DoW Offtake Agreement.
Under the terms of the DoW Offtake Agreement, certain costs related to the development and commissioning of the 10X Facility incurred prior to the Commercial Operation Date are reimbursable by the DoW. Reimbursements will be initially deferred as a contract liability and subsequently recognized into revenue as the Company fulfills its obligations under the contract. As of December 31, 2025, the contract liability for these reimbursements, which is included within the Consolidated Balance Sheets in non-current “Deferred revenue,” totaled $2.3 million. Furthermore, certain of these development and commissioning costs of the 10X Facility qualify for capitalization as costs to fulfill a contract with a customer. As of December 31, 2025, the Company capitalized $2.3 million of these contract fulfillment costs, which are included within the Consolidated Balance Sheets in “Other non-current assets.” These costs will be expensed following the pattern of revenue recognized from the reimbursements under the contract.

About Leases Disclosures

Lease disclosures under ASC 842 provide a comprehensive view of a company's leased asset portfolio, including the split between operating and finance leases, discount rates used to present-value future payments, and the maturity schedule of lease obligations. This section reveals a significant source of off-balance-sheet commitments that were largely hidden before the current standard.

Key signals: the weighted-average discount rate affects the size of recorded lease liabilities — a higher rate reduces the reported obligation, so compare the chosen rate against the company's incremental borrowing rate. The operating versus finance lease mix affects both EBITDA and operating income presentation. Watch the maturity table for concentration risk: large payment cliffs in specific years may create cash flow pressure. Variable lease payments excluded from the liability measurement represent real obligations that do not appear on the balance sheet. Compare total lease costs against prior-year operating lease expense to assess the true economic burden.
