Litigation and Contingencies

We may, from time to time, be involved in litigation and claims arising out of our operations in the normal course of business. In the ordinary course of business, we are sometimes threatened with or named as a defendant in various lawsuits seeking actual and punitive damages for personal injury and property damage. We maintain liability insurance with insurers in amounts and with coverage and deductibles management believes are reasonable and prudent, and which are generally accepted in the industry. However, there can be no assurance that the levels of insurance protection currently in effect will continue to be available at reasonable prices or that such levels will remain adequate to protect us from material expenses related to personal injury or property damage in the future. In addition, various regulatory agencies such as tax authorities, environmental agencies, or other such agencies may perform audits or reviews to ensure proper compliance with regulations. We are not fully insured for any claims that may arise from these various agencies and there can be no assurance that any claims arising from these activities would not have an adverse, material effect on our consolidated financial statements.

Environmental Remediation

We are subject to various federal, state and local environmental laws and make financial expenditures in order to comply with regulations governing underground storage tanks adopted by federal, state and local regulatory agencies. In particular, at the federal level, the Resource Conservation and Recovery Act of 1976, as amended, requires the EPA to establish a comprehensive regulatory program for the detection, prevention and cleanup of leaking underground storage tanks (e.g. overfills, spills and underground storage tank releases).

Federal and state regulations require us to provide and maintain evidence that we are taking financial responsibility for corrective action and compensating third parties in the event of a release from our underground storage tank systems and terminals. In order to comply with these requirements, we have historically obtained private insurance in the states in which we operate. These policies provide protection from third-party liability claims. During 2025, our coverage was$15 million per occurrence and in the aggregate. Our sites continue to be covered by these policies.

We are currently involved in the investigation and remediation of contamination at motor fuel storage and gasoline store sites where releases of regulated substances have been detected. We accrue for anticipated future costs and the related probable state reimbursement amounts for remediation activities. Accordingly, we have recorded estimated undiscounted liabilities for these sites totaling$168 million and $28 million as of December 31, 2025 and 2024, respectively, which are classified as accrued expenses andother current liabilities and other non-current liabilities.
