SUBURBAN PROPANE PARTNERS LP Commitments Disclosure

14. Commitments and Contingencies

Commitments. The Partnership leases certain property, plant and equipment, including portions of its vehicle fleet, for various periods under noncancelable leases.

Contingencies

Accrued Insurance. The Partnership is self-insured for general and product, workers’ compensation and automobile liabilities up to predetermined amounts above which third party insurance applies. As of September 27, 2025 and September 28, 2024, the Partnership had accrued liabilities of $56,685 and $58,070, respectively, representing the total estimated losses for known and anticipated or unasserted general and product, workers’ compensation and automobile claims. For the portion of the estimated liability that exceeds insurance deductibles, the Partnership records an asset within other assets (or prepaid expenses and other current assets, as applicable) related to the amount of the liability expected to be covered by insurance which amounted to $15,654 and $14,340 as of September 27, 2025 and September 28, 2024, respectively.

Legal Matters. The Partnership’s operations are subject to operating hazards and risks normally incidental to handling, storing and delivering combustible liquids such as propane. The Partnership has been, and will continue to be, a defendant in various legal proceedings and litigation as a result of these operating hazards and risks, and as a result of other aspects of its business. Although any litigation is inherently uncertain, based on past experience, the information currently available to the Partnership, and the amount of its accrued insurance liabilities, the Partnership does not believe that currently pending or threatened litigation matters, or known claims or known contingent claims, will have a material adverse effect on its results of operations, financial condition or cash flow.

The State of New York amended Section 349-d of the New York General Business Law (“GBL”) effective on March 18, 2024, to require that energy service companies that operate in the state, such as AES in connection with its natural gas and electricity business, first obtain written consent from the customer before any change in commodity prices can be charged to the customer. To date, the amended statute has not had a material negative impact on AES, but the Partnership continues to assess the impact that the GBL amendment may have in the future on its natural gas and electricity business. In addition, the New York Public Service Commission (“NY PSC”) has amended its Uniform Business Practices (“UBP”), that apply to AES and other energy supply companies that operate in the state. The UBP amendments require AES to provide notice to its customers that includes a historical comparison between the rates charged by AES and what the customer would have paid had they remained with their existing utility. The business model for AES provides for a bundled product offering in which a customer is charged one price for the commodity, plus the inclusion of a home warranty offering called EnergyGuard. This value-added warranty plan is a differentiator when comparing AES pricing with that of the local utility. The Partnership is working to enhance its communication of its value-added component in order to reduce the potential negative effect that the additional notice requirements mandated by the NY PSC could have on customer retention for energy supply companies.
