El Paso Corporation Reports Third Quarter Financial and Operational Results

HOUSTON, TEXAS, November 3, 2010—El Paso Corporation (NYSE:EP) is today reporting third quarter 2010 financial and operational results for the company.

Highlights:

• $0.22 adjusted diluted earnings per share (EPS) versus $0.23 in 2009. Higher pipeline earnings and E&P volumes were offset by lower realized natural gas prices, after hedges.

• Third quarter 2010 reported EPS of $0.19 per diluted share versus $0.08 in 2009.      

• Third quarter 2010 Pipeline Group earnings before interest expense and taxes (EBIT) rose 2 percent from the third quarter 2009.

• E&P oil opportunities are expanding with success in the Eagle Ford shale and a 135,000 net acre position in the Wolfcamp oil shale.

“Each quarter’s progress brings us closer to our long term goals,” said Doug Foshee, chairman, president, and chief executive officer of El Paso Corporation. “Both of our businesses continue to create value in the face of a challenging economic climate. Our pipeline group delivered another good quarter, and is poised to complete three expansions before year-end, all on-time and significantly under budget. In E&P, we continue to improve our execution, and, with our early entrance into the emerging Wolfcamp shale oil play, we have further expanded our portfolio of oil opportunities. In addition, the hedges we have in place through 2012 separate us from our peers in what could be a sustained period of low natural gas prices. Every aspect of our business remains focused on execution, which will allow us to reach our objective of substantial free cash flow in 2012.”

A summary of financial results for the quarters and nine-month periods ended September 30, 2010 and 2009 is as follows:

	Quarters Ended				Nine Months Ended

Diluted per common share amounts
Net income (loss) attributable to EPC common stockholders	$	0.19	$	0.08	$	0.90	$	(1.21	)

The effective tax rate for the nine months ended September 30, 2010 was approximately 30 percent, which is lower than the statutory rate, primarily due to an increase in income attributable to nontaxable noncontrolling interests, the tax impact of the sale of El Paso’s interests in Mexican pipeline and compression assets, and liquidation of certain foreign entities. The impact of these items was partially offset by $18 million of additional income tax expense recorded in the first quarter due to healthcare legislation enacted in March 2010, which reduces the tax deduction for certain retiree prescription drug expenses.

Pipeline Group

     The Pipeline Group reported EBIT of $334 million for the quarter ended September 30, 2010, compared with $326 million for the same period in 2009. Third quarter 2010 results benefited from higher reservation revenues, primarily due to higher rates on the Southern Natural Gas Company (SNG) system and the impact of several expansion projects that were placed in service in 2010, including the Elba Express Pipeline and the SLNG Elba Island LNG terminal expansion. Third quarter 2010 results were also favorably impacted by an increase in allowance for equity funds used during construction (AFUDC) on expansion projects that are not yet in service, principally the Ruby pipeline. Offsetting the effects of these favorable items was an increase in noncontrolling interests and a $21 million non-cash asset write down based on a Federal Energy Regulatory Commission order relating to the 2009 sale of the Natural Buttes compressor station and gas processing plant. In addition, continued regional economic and competitive challenges impacted El Paso Natural Gas Company (EPNG) results through lower realized rates and volumes on its recontracted capacity, while EBIT from Tennessee Gas Pipeline (TGP) declined due to lower pricing on its operational sales of retained fuel in excess of fuel used in operations as well as reduced long-haul transportation revenues on its system resulting from changing natural gas flows in the northeast.

Third quarter 2010 pipeline throughput was down 4 percent as compared with the third quarter 2009. Volumes rose on the TGP, SNG, and Cheyenne Plains systems due to production growth out of the Marcellus region, higher demand from local distribution companies and power generators in the Southeast, and an increase in Rockies production and export volumes, respectively. Throughput on EPNG was down from the third quarter 2009, primarily as a result of weaker demand in California and the Southwest as well as competition from another pipeline and LNG imports. Throughput on the Colorado Interstate Gas Company system was slightly lower than the third quarter 2009 due to reduced

production area deliveries. Approximately 80 percent of the company’s pipeline revenues are derived from demand charges under long-term contracts.

Pipeline Backlog Execution Update

The Pipeline Group expects to place three expansions in service on schedule, before year end — the WIC System Expansion, the CIG Raton 2010 expansion, and the first phase of the SNG South System III expansion. In total, these three projects are expected to be approximately $100 million, or 25 percent, under budget and within their original time frame.

Ruby has construction activity underway in all eight spreads along its 680-mile route. To date, permitting and construction are proceeding very well on the eastern portion of the pipeline route. However, there have been delays obtaining regulatory clearances in the western portion of the route. While the pace of obtaining regulatory clearances has recently improved, the delays are expected to push back Ruby’s in-service date from March 2011 to June 2011 and increase total project capital by 10 to 15 percent as compared to the original $3 billion budget. El Paso will bear all the construction cost increases pursuant to its arrangements with Ruby’s partner, Global Infrastructure Partners (GIP). The expected delay of the in-service date has no impact on the firm transportation contracts, the Ruby credit facility or the agreements with GIP.

Ruby continues to manage the significant variables impacting project execution, including the impact on contractor productivity from the duration and severity of winter weather, the timing of additional regulatory clearances and the ability to access certain sections of the route during specific windows that have been established to protect wildlife.

The remaining projects in the pipeline expansion backlog remain on track to be placed in service on-time and on-budget. In total, El Paso’s multi-year expansion backlog is expected to be placed in service within approximately 5 percent of budget.

Exploration and Production

The Exploration and Production segment reported $261 million of EBIT for the quarter ended September 30, 2010 compared with $88 million for the same period in 2009. Higher EBIT was primarily due to the mark-to-market impact of financial derivatives, higher volumes and commodity prices and a 9 percent reduction in per-unit cash costs. As a result of its successful efforts to reduce cash operating expenses, El Paso is updating its 2010 cash cost guidance to $1.75 to $1.85 per Mcfe. Third quarter 2010 DD&A expense was higher due to a higher depletion rate and higher production volumes. The company updated its full year 2010 DD&A guidance to be $1.80 to $1.85 per Mcfe.

Third quarter 2010 production volumes averaged 764 MMcfe/d, including 62 MMcfe/d of Four Star unconsolidated affiliate volumes, representing an increase of 32 MMcfe/d, or 4 percent, from third quarter 2009 production volumes, which averaged 732 MMcfe/d, including 71 MMcfe/d of Four Star unconsolidated affiliate volumes. Higher year to year volumes reflect substantial growth from the company’s Haynesville shale program and increased production in Brazil.

During the third quarter 2010, El Paso was the winning bidder for leases covering approximately 123,000 acres in Reagan, Crockett, Upton, and Irion counties in the September 22, 2010 University of Texas lease sale. The leases, when added to approximately 12,000 net acres of existing leasehold nearby, give the company a large position for its newest horizontal oil program, the Wolfcamp shale.

Hedge Positions

El Paso actively manages it exposure to commodity prices using various hedging strategies. The company recently expanded its natural gas hedge position in 2011 and established a position in 2012. A summary of natural gas and oil hedge positions can be found in the Third Quarter 2010 Financial & Operational Reporting Package at www.elpaso.com in the Investors section or in El Paso’s Form 10-Q.

Other Operations

The Marketing segment reported an EBIT loss of $12 million for the quarter ended September 30, 2010, compared with a $28 million loss for the same period in 2009. Third quarter 2010 and third quarter 2009 results were impacted primarily by changes in the fair value of legacy power contracts.

During the third quarter of 2010, Corporate and Other reported an EBIT loss of $111 million, compared with a $28 million loss for the same period in 2009. Third quarter 2010 results were primarily impacted by a loss of $104 million associated with the exchange of $348 million of 12.00% Senior Notes due 2013 for 6.50% Senior Notes due 2020 and cash consideration. The third quarter 2009 loss is primarily related to legacy litigation and environmental remediation cost.

Disclosure of Non-GAAP Financial Measures

The Securities and Exchange Commission (SEC)’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.

El Paso uses the non-GAAP financial measure “earnings before interest expense and income taxes” or “EBIT” to assess the operating results and effectiveness of the company and its business segments, which consist of both consolidated businesses and investments in unconsolidated affiliates. The company believes that EBIT is useful to its investors because it allows them to evaluate more effectively the performance of all El Paso’s businesses and investments using the same performance measure analyzed internally by our management and so that our investors may evaluate the company’s operating results without regard to its financing methods or capital structure. The company defines EBIT as net income (loss) adjusted for items such as (i) interest and debt expense; (ii) income taxes; and (iii) net income attributable to noncontrolling interests.

Adjusted EPS is defined as diluted earnings per share adjusted for certain items that we consider 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 our results. 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 gain on the sale of Mexican pipeline assets, the loss on debt extinguishment, the impact of health care legislation, a tax benefit from liquidation of foreign entities and the impact of the estimated annual effective tax rate on adjustments. For 2009, 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 loss on sale of notes receivable relating to the Porto Velho sale, and the effect of the change in the number of diluted shares.

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. El Paso owns North America’s largest interstate natural gas pipeline system and one of North America’s largest independent natural gas producers. For more information, visit www.elpaso.com.
