Operating lease payments in the table above include approximately $16 million related to options to extend lease terms that are reasonably certain of being exercised. At December 31, 2025, we had operating lease commitments of approximately $0.2 million and finance lease commitments of approximately $8 million, which are not included in the above table. Most of the commitments relate to equipment that is being constructed or procured by the future lessors and office space. These leases are expected to commence in 2026.

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.
