NOTE 7—LEASES

The Company has various finance leases for mining equipment, which generally include 3-5 year terms and expire through 2030. In addition, we have two operating leases for office space with initial terms of approximately five and six years that run through 2027 and 2030, respectively, including the office space in Charleston, WV that commenced in the first quarter of 2024 resulting in the recognition of an additional right-of-use asset and lease liability of approximately $1.0 million.

Amortization of right-of-use assets associated with finance leases was $7.8 million, $10.4 million, and $8.5 million in 2025, 2024, and 2023, respectively, as discussed in Note 3. Interest expense recognized for financing lease liabilities was $1.5 million, $0.9 million, and $0.6 million in 2025, 2024, and 2023, respectively. Operating lease expense was $0.4 million, $0.4 million, and $0.2 million in 2025, 2024, and 2023, respectively.

Right-of-use assets and lease liabilities are determined as the present value of the lease payments, discounted using either the implicit interest rate in the lease or, more commonly, our estimated incremental borrowing rate based on similar terms, payments and the economic environment where the leased asset is located. Below is a summary of our leases:

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.
