El Paso Corporation Reports Strong First Quarter 2011 Results; Advancing 2011 Goals

HOUSTON, TEXAS, May 5, 2011—El Paso Corporation (NYSE:EP) is today reporting first quarter 2011 financial and operational results for the company. Key highlights include:

	-		$0.30 adjusted diluted earnings per share (EPS) for first quarter 2011
	-		First quarter E&P production volumes of 821 million cubic feet equivalent per day (MMcfe/d), including Four Star Oil & Gas Company (Four Star) unconsolidated affiliate volumes, up 5 percent from first quarter 2010, including an 18 percent increase in oil and condensate production
	-		Florida Gas Transmission (FGT) Phase VIII pipeline expansion on budget and placed in-service April 1
	-		Positive initial results from Wolfcamp Shale program
	-		Successful MLP drop-down with proceeds being used to reduce outstanding debt

“We are off to an excellent start, financially and operationally,” said Doug Foshee, chairman, president, and chief executive officer of El Paso Corporation. “Our initial drilling results in the Wolfcamp Shale are encouraging, and we are excited about the potential for our 138,000 net acre position. This program, along with results in the Eagle Ford Shale and Altamont provide us with many years of profitable oil inventory. In our Pipeline Group, we continue to work towards the completion of what was an $8 billion pipeline backlog in 2008. On April 1, the FGT Phase VIII expansion was placed in service on time and on budget, and we have four more major projects coming on-line this year. And we continue to execute our MLP strategy, with a major drop-down completed in March, the proceeds of which are being used to pay down debt and accelerate our balance sheet improvement. This, along with other future drop-downs to El Paso Pipeline Partners, L.P. are expected to result in continued distribution growth for limited partner unit holders and rapid growth in El Paso Corporation’s general partner distributions. We look forward to continued progress across all of our businesses during the remainder of the year.”

Financial Results — First Quarter 2011

For the first quarter 2011, El Paso reported net income attributable to EPC common stockholders of $62 million, or $0.08 per diluted share, compared with net income of $379 million, or $0.51 per diluted share, for the first quarter 2010. Earnings for first quarter 2011 and 2010, after adjusting for impacts of E&P financial derivatives and other items, were $0.30 and $0.33 per diluted share, respectively.

El Paso’s effective tax rate for reported earnings for the quarter ended March 31, 2011 was 12 percent, which was favorably impacted by the resolution of several tax matters and earned state tax credits. Absent these items, the effective rate for the quarter would have been 22 percent. The company’s effective tax rate is expected to remain well below the statutory rate due to the growth of earnings attributable to noncontrolling interests as a result of its drop-down activities with El Paso Pipeline Partners, L.P.

Note: On January 1, 2011, El Paso began using the non-GAAP financial measure, Segment EBIT, and the 2010 amounts have been conformed to reflect this current performance measure. Refer to the Disclosure of Non-GAAP Financial Measures later in this release for a definition of Segment EBIT.

Pipeline Group

The Pipeline Group’s Segment EBIT for the quarter ended March 31, 2011 was $499 million, compared with $452 million for the same period in 2010. First quarter 2011 results benefited from higher reservation revenues due to several expansion projects that went into service during 2010. First quarter 2011 results were also favorably impacted by allowance for equity funds used during construction on expansion projects that are not yet in service, principally the Ruby pipeline. Offsetting the effects of these favorable items was lower reservation revenue on the El Paso Natural Gas system due to competitive pressures and the effects of a weak economy in California and the southwest portion of the country.

Exploration and Production

The Exploration and Production segment reported a $31 million loss in Segment EBIT for the quarter ended March 31, 2011, compared with $390 million of Segment EBIT for the same period in 2010. The principal reason for the decline was a $362 million quarter-to-quarter change in the mark-to-market impacts of financial derivatives. Also contributing to the decline were lower natural gas prices and a higher per-unit DD&A rate. Partially offsetting these factors were higher production volumes and higher oil and condensate prices.

First quarter 2011 production volumes averaged 821 MMcfe/d, including 63 MMcfe/d of Four Star unconsolidated affiliate volumes. First quarter 2010 production volumes averaged 781 MMcfe/d, including 64 MMcfe/d of Four Star unconsolidated affiliate volumes. While total volumes rose 5 percent, oil and condensate volumes were 18 percent higher as a result of an

increased focus on oil programs. Total per-unit cash operating costs decreased to an average of $1.85 per Mcfe in the first quarter 2011, down from $1.88 per Mcfe for the same period in 2010, primarily due to higher production volumes.

Hedge Positions

The company actively manages its exposure to commodity prices using various hedging strategies. During the quarter, the company entered into additional natural gas hedges for the remainder of 2011. After adding these positions, approximately 80 percent of the company’s remaining 2011 domestic natural gas production is hedged at an average floor price of $5.78 per MMBtu. Approximately 85 percent of the company’s remaining 2011 oil production is hedged with a floor of $85.99 and a ceiling of $91.88. Further information on the company’s hedging activities will be available in El Paso’s Financial and Operational Reporting Package for First Quarter 2011, which can be found in the Investors section of El Paso’s website.

Marketing

Marketing reported a Segment EBIT loss of $14 million for the quarter ended March 31, 2011, compared with $17 million of Segment EBIT for the same period in 2010. First quarter 2011 includes a $15 million loss related to settlements on an affiliated fuel supply agreement. First quarter 2010 includes an $18 million mark-to-market gain on the remaining Pennsylvania-New Jersey-Maryland power contracts.

Other Operations

During the first quarter of 2011, Segment EBIT from Other Operations was a loss of $59 million, compared with a loss of $11 million for the same period in 2010. First quarter 2011 results include a $41 million loss associated with the repurchase of approximately $148 million of debt.

Other activities also include the company’s midstream operations. In late 2010, El Paso sold a 50-percent interest in its Altamont gathering and processing assets to a private equity investor as a part of the formation of a joint-venture, El Paso Midstream Investment Co. El Paso’s interest in this company is reported as an unconsolidated affiliate. The joint-venture expects to develop future midstream projects as well as expand the Altamont assets. For the quarter

ended March 31, 2011, the midstream operations contributed $2 million to Segment EBIT, which included $3 million of equity earnings from El Paso Midstream Investment Co.

Detailed financial and operational information for the company will be posted at www.elpaso.com in the Investors section.

Disclosure of Non-GAAP Financial Measures

The Securities and Exchange Commission’s Regulation G applies to any public disclosure or release of material information that includes a non-GAAP financial measure. In the event of such a disclosure or release, Regulation G requires (i) the presentation of the most directly comparable financial measure calculated and presented in accordance with GAAP and (ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most directly comparable financial measure calculated and presented in accordance with GAAP. The required presentations and reconciliations are attached, or included in the body of this release. Additional detail regarding non-GAAP financial measures can be reviewed in El Paso’s Financial and Operational Reporting Package, which will be posted at www.elpaso.com in the Investors section.

On January 1, 2011, El Paso began using the non-GAAP financial measure “segment earnings before interest expense and income taxes” or “Segment EBIT” to assess the operating results and effectiveness of the company and its business segments. The company believes that

Segment EBIT is useful to its investors because it allows them to use the same performance measure analyzed internally by our management to evaluate the performance of our businesses and investments without regard to the manner in which they are financed or the company’s capital structure. The company defines Segment EBIT as net income (loss) adjusted for interest and debt expense and income taxes. Segment EBIT does not reflect a reduction for any amounts attributable to noncontrolling interests. The 2010 amounts have been conformed to reflect the company’s current performance measure.

Adjusted EPS is defined as diluted earnings per share adjusted for certain items that the company considers to be significant to understanding our underlying performance for a given period. Adjusted EPS is useful in analyzing the company’s on-going earnings potential and understanding certain significant items impacting the comparability of El Paso Corporation’s results. For 2011, Adjusted EPS is earnings per share attributable to El Paso Corporation common stockholders adjusted for the impact of E&P financial derivatives, and excluding a loss on debt extinguishment and the impact of the estimated annual effective tax rate. For 2010, Adjusted EPS is earnings per share attributable to El Paso Corporation common stockholders adjusted for the impact of E&P financial derivatives, and excluding ceiling test charges, changes in legacy derivative contracts and other legacy items, the impact of health care legislation, and impact of the estimated annual effective tax rate.

Exploration and Production per-unit total cash operating costs is a non-GAAP measure calculated on a per Mcfe basis equal to total operating expenses less DD&A, transportation costs, costs of products and services, and ceiling test charges and other impairment divided by total consolidated equivalent production. It is a valuable measure used by oil and gas companies and analysts to evaluate operating performance and efficiency.

El Paso believes that the non-GAAP financial measures described above are also useful to investors because these measurements are used by many companies in the industry as a measurement of operating and financial performance and are commonly employed by financial analysts and others to evaluate the operating and financial performance of the company and its business segments and to compare it with the performance of other companies within the industry. These non-GAAP financial measures may not be comparable to similarly titled measures used by other companies and should not be used as a substitute for net income, earnings per share or other measures of financial performance presented in accordance with GAAP.

El Paso Corporation provides natural gas and related energy products in a safe, efficient, and dependable manner. The company owns North America’s largest interstate natural gas pipeline system, one of North America’s largest independent oil and natural gas producers and an emerging midstream business.
