FOR IMMEDIATE RELEASE

Suburban Propane Partners, L.P.

Announces Second Quarter Earnings

Whippany, New Jersey, May 4, 2017 -- Suburban Propane Partners, L.P. (NYSE:SPH), a nationwide distributor of propane, fuel oil and related products and services, as well as a marketer of natural gas and electricity, today announced earnings for its second quarter ended March 25, 2017.

Net income for the second quarter of fiscal 2017 was $83.8 million, or $1.37 per Common Unit, compared to net income of $92.0 million, or $1.51 per Common Unit, in the prior year second quarter.

Net income and earnings before interest, taxes, depreciation and amortization (“EBITDA”) for the second quarters of fiscal 2017 and 2016 included losses on debt extinguishment of $1.6 million and $0.3 million, respectively. Excluding the effects of the foregoing items and unrealized (non-cash) mark-to-market adjustments on derivative instruments in both periods, Adjusted EBITDA (as defined and reconciled below) amounted to $138.0 million for the second quarter of fiscal 2017, compared to $145.1 million in the prior year second quarter.

In announcing these results, President and Chief Executive Officer Michael A. Stivala said, “The propane industry as a whole has just endured an unprecedented stretch of back-to-back record warm winters.  The fiscal 2017 heating season was a bit more challenging than the prior year, with four out of six months reported as record warm, and two separate three-week stretches of cold weather toward the end of each of the first and second quarters.  Nonetheless, we are proud of the way our operating personnel managed through the challenges presented by this sustained warm weather trend.  We remain focused on the things we can control – delivering exceptional customer satisfaction in every market we serve, driving further operating efficiencies, controlling costs and capital spending levels, managing margins in a challenging commodity price environment and executing on our customer base growth and retention initiatives. During the short bursts of cold weather that did arrive, our volumes and earnings responded as expected, which is a testament to the strength and readiness of our platform.”

Mr. Stivala continued, “As a result, we are pleased to report an improvement of $10 million, or nearly 5%, in Adjusted EBITDA for the first half of fiscal 2017 compared to the prior year.  We also took proactive steps to lower our interest costs and enhance liquidity.  During the second quarter of fiscal 2017, we successfully refinanced our previous 7 3/8% Senior Notes due 2021 with the issuance of 5 7/8% Senior Notes due 2027, effectively extending maturities on $350.0 million of our debt by six years at a very attractive interest rate, and reducing our cash interest requirement by nearly $5.0 million annually.”  

On May 1, 2017, the Partnership secured an amendment to its revolving credit facility whereby the maximum consolidated leverage ratio covenant has been increased from 5.50 to 5.95 starting with the fiscal quarter ending June 2017 and continuing through each of the fiscal quarters ending June 2018, stepping down to 5.75 for the

quarter ending September 2018 and then returning to the pre-amendment level of 5.50 for the fiscal quarter ending December 2018, which is the Partnership’s first quarter of fiscal 2019.  

Discussing the amendment, Mr. Stivala said, “Our decision to secure this amendment was to proactively enhance our liquidity position in light of the recent warm weather trends.  The amendment provides added cushion under our consolidated leverage test, which we believe is a prudent measure that gives us added flexibility to support our cash needs and continue to invest in our long-term, strategic growth initiatives.  We received strong support from our bank group for this amendment, which is a testament to their confidence in our operating philosophy and business fundamentals.”

Retail propane gallons sold in the second quarter of fiscal 2017 of 153.9 million gallons decreased 7.7 million gallons, or 4.8%, compared to the prior year second quarter. Sales of fuel oil and other refined fuels decreased 0.3 million gallons, or 2.3%, compared to the prior year. According to the National Oceanic and Atmospheric Administration, average temperatures (as measured by heating degree days) across all of the Partnership’s service territories for the second quarter of fiscal 2017 were 15% warmer than normal, and 2% warmer than the prior year second quarter. In certain markets, principally the Partnership’s Midwest and Southeast service territories, average temperatures were approximately 30% warmer than normal and 16% warmer than the prior year second quarter.  In the Partnership’s Northeast and West Coast regions, the Partnership experienced cooler weather compared to the prior year which helped contribute to an increase in volumes sold in those markets.  

Revenues in the second quarter of fiscal 2017 of $450.6 million increased $46.4 million, or 11.5%, compared to the prior year second quarter, primarily due to higher retail selling prices associated with higher wholesale product costs, offset to an extent by lower volumes sold. Average posted propane prices (basis Mont Belvieu, Texas) and fuel oil prices were 84.6% and 48.9% higher than the prior year, respectively. Cost of products sold for the second quarter of fiscal 2017 of $192.5 million increased $55.5 million, or 40.5%, compared to $137.0 million in the prior year, primarily due to higher wholesale product costs. Cost of products sold included a $2.5 million unrealized (non-cash) loss attributable to the mark-to-market adjustment for derivative instruments used in risk management activities, compared to a $0.7 million unrealized (non-cash) loss in the prior year second quarter. These unrealized losses are excluded from Adjusted EBITDA for both periods in the table below.  

Combined operating and general and administrative expenses of $122.6 million for the second quarter of fiscal 2017 were essentially flat with the prior year second quarter. Savings in fixed costs due to steps taken in the prior fiscal year to streamline operations and achieve operating efficiencies were offset by higher general insurance expenses, vehicle fuel costs, and higher provisions for potential uncollectible accounts as a result of higher commodity prices.

Depreciation and amortization expense of $32.7 million decreased $0.5 million, or 1.5%, compared to the prior year second quarter. Net interest expense of $17.5 million decreased $1.4 million compared to the prior year second quarter, primarily due to savings from the refinancing of the Partnership’s previously outstanding 2021 Senior Notes.

During the second quarter of fiscal 2017, the Partnership funded working capital, capital expenditures and costs associated with the repurchase of its 2021 Senior Notes from operating cash flow and $26.4 million of incremental borrowings under its revolving credit facility.

As previously announced on April 20, 2017, the Partnership’s Board of Supervisors has declared a quarterly distribution of $0.8875 per Common Unit for the three months ended March 25, 2017. On an annualized basis, this distribution rate equates to $3.55 per Common Unit. The distribution is payable on May 9, 2017 to Common Unitholders of record as of May 2, 2017.
