FOR IMMEDIATE RELEASE

Suburban Propane Partners, L.P. Announces Third Quarter Results

and Successful Completion of the Acquisition of Inergy, L.P.’s Retail Propane

Operations

Whippany, New Jersey, August 2, 2012 — Suburban Propane Partners, L.P. (NYSE:SPH) (the “Partnership”), a nationwide distributor of propane, fuel oil and related products and services, as well as a marketer of natural gas and electricity, today announced results for its third quarter ended June 23, 2012. The Partnership also today announced the successful completion of its acquisition of Inergy L.P.’s retail propane operations, effective August 1, 2012 (the “Inergy Propane Acquisition”).

Third Quarter Results

Consistent with the seasonal nature of the propane and fuel oil businesses, the Partnership typically experiences a net loss in the third quarter. Net loss for the three months ended June 23, 2012 was $9.3 million, or $0.26 per Common Unit, compared to a net loss of $6.8 million, or $0.19 per Common Unit, in the prior year third quarter. Net loss for the fiscal 2012 third quarter included $5.9 million in acquisition-related costs associated with the aforementioned acquisition of Inergy, L.P.’s retail propane operations which was announced on April 26, 2012. Excluding the effects of these acquisition-related costs from the fiscal 2012 third quarter, as well as the unrealized (non-cash) mark-to-market adjustments on derivative instruments used in risk management activities in both quarters, Adjusted EBITDA amounted to $3.5 million for the fiscal 2012 third quarter, compared to Adjusted EBITDA of $10.3 million in the prior year third quarter.

Retail propane gallons sold in the third quarter of fiscal 2012 decreased approximately 5.6 million gallons, or 10.3%, to 49.0 million gallons compared to 54.6 million gallons in the prior year third quarter. Sales of fuel oil and other refined fuels decreased approximately 1.3 million gallons, or 23.2%, to 4.3 million gallons during the third quarter of fiscal 2012, compared to 5.6 million gallons in the prior year third quarter. The most significant factor impacting volumes in both segments during the third quarter of fiscal 2012 was a near-record warm April 2012, which added to the effects of a record warm second quarter of fiscal 2012, across the Partnership’s service territories. The month of April 2012 was the third warmest on record for the contiguous United States, according to the National Oceanic and Atmospheric Administration, which has been keeping records since 1895. Average temperatures (as measured by heating degree days) across all of the Partnership’s service territories for the third quarter of fiscal 2012 were 16% warmer than both normal and the prior year third quarter.

Revenues of $179.6 million decreased $37.0 million, or 17.1%, compared to the prior year third quarter, primarily due to lower volumes sold and, to a lesser extent, lower average selling prices in the propane segment attributable to lower wholesale propane costs. Average posted prices for propane and fuel oil during the fiscal 2012 third quarter were 34.8% and 5.0% lower, respectively, compared to the prior year third quarter.

Cost of products sold for the third quarter of fiscal 2012 of $88.8 million decreased $36.4 million, or 29.1%, compared to $125.2 million in the prior year third quarter. Cost of products sold in the third quarter of fiscal 2012 included an $8.2 million unrealized (non-cash) gain attributable to the mark-to-market adjustment for derivative instruments used in risk management activities, compared to a $0.3 million unrealized (non-cash) loss in the prior year third quarter. These unrealized gains and losses are excluded from Adjusted EBITDA for both periods in the table below.

Combined operating and general and administrative expenses of $79.1 million for the third quarter of fiscal 2012 were $2.3 million, or 2.8%, lower than the prior year third quarter, primarily due to continued savings in payroll and benefit related expenses and lower variable compensation attributable to lower earnings.

Once again, the Partnership funded all working capital requirements with cash on hand without the need to borrow under its working capital facility and ended the third quarter of fiscal 2012 with approximately $116 million of cash. On July 18, 2012, the Partnership announced that its Board of Supervisors had declared a quarterly distribution of $0.8525 per Common Unit for the three months ended June 23, 2012. On an annualized basis, this distribution rate equates to $3.41 per Common Unit. The $0.8525 per Common Unit distribution will be paid on August 7, 2012 to Common Unitholders of record as of July 31, 2012.

As previously announced on April 26, 2012, the Partnership’s Board of Supervisors approved an increase in the annualized distribution rate to $3.50 per Common Unit (conditioned on the closing of the Inergy Propane Acquisition) which represents an increase of $0.09 per Common Unit, or 2.6%, compared to our current annualized distribution rate. With today’s announcement of the closing of this acquisition, the Partnership reaffirms the distribution at the increased rate, which will be effective for the quarterly distribution paid in respect of the first quarter of fiscal 2013 ending December 29, 2012.

Acquisition of Inergy, L.P.’s Retail Propane Operations

The Partnership also announced today that it has successfully completed the acquisition of Inergy L.P.’s (“Inergy”) retail propane operations, effective August 1, 2012. The stated purchase price of the acquisition was approximately $1.8 billion. The acquisition adds approximately 600,000 propane customers and nearly 300 million retail propane gallons sold. With this acquisition, Suburban believes that it is now the third largest retail marketer of propane in the United States, as measured by retail gallons sold by both companies in the calendar year 2011.

In connection with the Inergy Propane Acquisition, the Partnership successfully completed on August 1, 2012, its previously announced offers to exchange (“Exchange Offers”) and related

consent solicitations in connection with certain outstanding notes of Inergy, pursuant to which it issued $496.6 million principal amount of new unsecured 7  ¹/₂% Senior Notes due 2018 and $503.4 million principal amount of new unsecured 7 ³/₈% Senior Notes due 2021, and paid $184.8 million in cash to Inergy noteholders pursuant to the Exchange Offers. Additionally, the Partnership distributed 14.2 million new Suburban common units to Inergy, of which all but 0.1 million common units will subsequently be distributed by Inergy to its unitholders.

In announcing the closing of this transaction, President and Chief Executive Officer Michael J. Dunn, Jr., said, “We are extremely pleased to complete the Inergy Propane Acquisition, which brings together two of the largest and finest retail propane businesses in the propane industry. We welcome the employees of Inergy’s retail propane business to the Suburban family and look forward to achieving extraordinary things together in our quest to provide unparalleled service to our customers and value for our unitholders. We would also like to thank all of the Suburban and Inergy employees who have worked tirelessly over the last few months to prepare for this day.”

Mr. Dunn added, “Our integration plans are well established, and we are poised, starting today, to begin combining operations into one company that serves approximately 1.3 million customers in 41 states. We will continue to follow the path that has brought us to this point, by leveraging the investments we have made in people and technology across our newly expanded service territories and customer base, in order to further strengthen our operating platform and achieve our ultimate goal of delivering sustainable, profitable growth for our valued unitholders.”

In addition, certain of our incentive compensation plans covering executives and other employees utilize Adjusted EBITDA as the performance target. Moreover, our revolving credit agreement requires us to use Adjusted EBITDA as a component in calculating our leverage and interest coverage ratios. EBITDA and Adjusted EBITDA are not recognized terms under accounting principles generally accepted in the United States of America (“US GAAP”) and should not be considered as an alternative to net income or net cash provided by operating activities determined in accordance with US GAAP. Because EBITDA and Adjusted EBITDA as determined by us excludes some, but not all, items that affect net income, they may not be comparable to EBITDA and Adjusted EBITDA or similarly titled measures used by other companies.
