SUNOCO REPORTS FIRST QUARTER 2011 RESULTS

PHILADELPHIA, May 5, 2011 — Sunoco, Inc. (NYSE: SUN) today reported a net loss attributable to Sunoco shareholders of $101 million ($0.84 per share diluted) for the first quarter of 2011 versus a net loss attributable to Sunoco shareholders of $63 million ($0.53 per share diluted) for the first quarter of 2010. Excluding special items, Sunoco had a loss of $122 million ($1.01 per share diluted) for the first quarter of 2011 versus first quarter 2010 income of $17 million ($0.14 per share diluted). Key first quarter details include:

“The sharp rise in crude oil prices created very challenging market conditions in the first quarter which, along with some significant operational reliability issues at two of our refineries, negatively impacted earnings. We have been aggressively focused on addressing the reliability issues,” said Lynn L. Elsenhans, Sunoco’s Chairman and Chief Executive Officer. “During the first quarter, we continued to make progress on growing our retail and logistics businesses and separating SunCoke Energy from Sunoco. We finished the quarter with approximately $1.5 billion in cash, which gives us strategic flexibility to further pursue our growth plans.”

Commenting on the coke business, Elsenhans said, “The recent filing of SunCoke’s registration statement with the Securities and Exchange Commission represents an important step in the separation process. We also have an

exceptional and experienced management team in place and we expect to complete the relocation of SunCoke’s corporate headquarters to the Chicago area in May. Establishing SunCoke as an independent company remains a priority.”

DETAILS OF FIRST QUARTER RESULTS

FUELS BUSINESS RESULTS

Refining and Supply

Refining and Supply had a pretax loss of $138 million in the current quarter versus a loss of $70 million in the first quarter of 2010. The $68 million decrease in results was primarily due to lower realized margins and production volumes. The overall crude utilization rate was 74 percent for the quarter, down from 85 percent in the fourth quarter of 2010. Production volumes were negatively affected by significant unplanned maintenance activities at the Philadelphia and Marcus Hook refineries during the first quarter of 2011.

Retail Marketing

Retail Marketing earned $12 million pretax in the current quarter versus $34 million in the first quarter of 2010. The decrease in earnings was primarily due to lower average retail gasoline margins largely driven by the inability to fully pass-through wholesale price increases caused by the run up in crude prices.

Logistics

Logistics earned $31 million pretax in the first quarter of 2011 versus $27 million in the first quarter of 2010. The improvement in results was primarily due to higher lease acquisition results and earnings attributable to recent acquisitions and organic growth projects.

Chemicals - Continuing Operations

Chemicals had a pretax loss of $9 million in the first quarter of 2011 versus income of $5 million in the first quarter of 2010. The decrease in results was primarily attributable to the unplanned refinery downtime at the Company’s Philadelphia refinery which limited supply of cumene to the Frankford phenol facility, raising feedstock costs and reducing production.

Chemicals - Discontinued Polypropylene Operations

Discontinued polypropylene operations, which were divested on March 31, 2010, had pretax income of $33 million in the first quarter of 2010.

2

COKE BUSINESS RESULTS

Coke earned $9 million pretax in the first quarter of 2011 versus $51 million in the first quarter of 2010. The decrease in earnings was attributable to lower coke sales revenues as a result of the Jewell contract restructuring with ArcelorMittal in January 2011 and a $25 million decline in results at the Indiana Harbor cokemaking facility due to lower coal-to-coke yields, higher maintenance expenses and the recognition of a $13 million contract loss in connection with agreements to purchase coke from third-parties to cover the projected 2011 production shortfall.

OTHER

Corporate administrative expenses were $22 million pretax in the first quarter of 2011 versus $23 million in the first quarter of 2010.

Net financing expenses and other were $24 million pretax in the first quarter of 2011 compared to $28 million in the first quarter of 2010. The decrease was primarily driven by higher interest income and capitalized interest, partially offset by higher interest expense.

INCOME TAXES

Excluding the impact of special items, the effective tax rates on pretax income attributable to Sunoco, Inc. shareholders for the first quarter of 2011 and 2010 were 13 and 41 percent, respectively. The effective tax rates for each quarter were determined based upon the expected full year tax rates at the end of each quarter. The reduction in the effective rate in 2011 is largely attributable to the estimated impact of nonconventional fuel tax credits and higher coal depletion deductions combined with lower expected pretax earnings.

SPECIAL ITEMS

During the first quarter of 2011, Sunoco recognized a $15 million gain ($4 million after tax) related to the divestment of the Toledo refinery and related inventory; recognized a $42 million gain ($26 million after tax) resulting from the reduction of crude oil and refined product inventories at the Toledo refinery prior to its divestment; recorded a $6 million provision ($4 million after tax) primarily for pension settlement losses in connection with business improvement initiatives; and recorded a $5 million increase to deferred income taxes in part due to apportionment changes as a result of the sale of the Toledo refinery. The total net impact of special items during the first quarter of 2011 was a pretax gain of $51 million ($21 million after tax).

During the first quarter of 2010, Sunoco recorded a $169 million loss ($44 million after tax) related to the divestment of the discontinued polypropylene operations; recorded a $33 million provision ($20 million after tax) primarily related to contract losses in connection with excess barge capacity resulting from the permanent shutdown of the Eagle Point refinery during 2009; recorded a $12 million provision ($7 million after tax) primarily for pension settlement losses in connection with business improvement initiatives; and recorded a $9 million increase in deferred state income taxes attributable to the transfer of assets related to its continuing

phenol chemicals operations to a different legal entity subsequent to the sale of the stock of the discontinued polypropylene business. The total net impact of special items during the first quarter of 2010 was a pretax loss of $214 million ($80 million after tax).
