Leases
Lessee Arrangements
The Company has operating and finance leases primarily for vehicles, equipment, railcars, office space, and facilities. The terms and conditions for these leases vary by the type of underlying asset.
Certain leases include variable lease payments for items such as property taxes, insurance, maintenance, and other operating expenses associated with leased assets. Payments that vary based on an index or rate are included in the measurement of lease assets and liabilities at the rate as of the commencement date. All other variable lease payments are excluded from the measurement of lease assets and liabilities, and are recognized in the period in which the obligation for those payments is incurred.
The components of lease expense for the years ended as of December 31, 2025, and 2024 were as follows:

During the year ended December 31, 2024, the Company amended certain operating leases, the change in terms of which caused the leases to be reclassified as finance leases. Additionally, the Company recognized finance lease right-of-use assets of $4.4 million and liabilities of $4.3 million. There was no gain or loss recognized as a result of these amendments. During the year ended December 31, 2025, the Company did not amend any operating or finance leases.

The Company’s vehicle leases typically include a residual value guarantee. For the Company’s vehicle leases classified as operating leases, the total residual value guaranteed as of December 31, 2025 is $12.5 million; the payment is not probable and therefore has not been included in the measurement of the lease liability and right-of-use asset. For vehicle leases that are
classified as finance leases, the Company includes the residual value guarantee, estimated in the lease agreement, in the financing lease liability.
Lessor Arrangements
The Company leases dry and wet sand containers, conveyor belts, and other equipment to customers through operating leases, where the lessor for tax purposes is considered to be the owner of the equipment during the term of the lease. The lease agreements do not include options for the lessee to purchase the underlying asset at the end of the lease term for either a stated fixed price or fair market value. However, some of the leases contain a termination clause in which the customer can cancel the contract. The leases can be subject to variable lease payments if the customer requests more units than what is agreed upon in the lease. The Company does not record any lease assets or liabilities related to these variable items.
The carrying amount of equipment leased to others, included in property, plant and equipment, under operating leases as of December 31, 2025 and 2024 were as follows:

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.
