**Announces Pricing of Private Offering of Senior Notes** 

**Whippany, New Jersey, December 8, 2025 — Suburban Propane Partners, L.P. (NYSE:SPH)** ("Suburban Propane"), announced today the pricing of its offering of $350,000,000 aggregate principal amount of 6.500% senior notes due 2035 (the "2035 Senior Notes") in a private placement not registered under the Securities Act of 1933, as amended (the "Securities Act"), at par. Suburban Energy Finance Corp., a wholly-owned direct subsidiary of Suburban Propane (together with Suburban Propane, the "Issuers"), is the co-issuer of the 2035 Senior Notes. The sale of the 2035 Senior Notes is expected to close on December 22, 2025, subject to customary closing conditions.

The 2035 Senior Notes will bear interest at a rate of 6.500% per year and mature on December 15, 2035. Interest on the notes will be payable semi-annually on June 15 and December 15 of each year, commencing June 15, 2026. Before December 15, 2028, Suburban Propane may redeem up to 35% of the aggregate principal amount of outstanding 2035 Senior Notes with the net proceeds from certain offerings of its common units at a redemption price equal to 106.500% of their principal amount, plus accrued and unpaid interest, if any, to the redemption date. On or after December 15, 2030, Suburban Propane may redeem the 2035 Senior Notes subject to applicable redemption premiums. In addition, prior to December 15, 2030, Suburban Propane may redeem the 2035 Senior Notes at a "make whole" premium plus accrued and unpaid interest.

Suburban Propane intends to use the net proceeds from the offering, together with borrowings under its revolving credit facility, to redeem all the outstanding $350,000,000 aggregate principal amount of the Issuers' 5.875% senior notes due 2027.

The 2035 Senior Notes are being offered only (1) in the United States to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act; and (2) outside the United States to persons other than "U.S. persons" in compliance with Regulation S under the Securities Act.
