Duke Energy Reports Second-Quarter 2007 Results

• Ongoing diluted earnings per share (EPS) of 25 cents versus 24 cents in the prior year’s quarter.

• Combined ongoing results at Franchised Electric and Gas, Commercial Power and International improved 7 cents, compared to the prior-year quarter. These results were offset by a lower contribution from Crescent.

• Reported diluted EPS of 23 cents versus 28 cents in the previous year’s quarter, which included Spectra Energy.

• Company expects to exceed annual employee ongoing diluted EPS incentive target of $1.15.

CHARLOTTE, N.C. – Duke Energy today reported ongoing diluted earnings per share (EPS) of 25 cents for second-quarter 2007, which excludes special items and discontinued operations, versus 24 cents in second-quarter 2006.

The 24 cents excludes the results of the natural gas businesses, spun off as Spectra Energy in January 2007, the results of which are now reported in Discontinued Operations.

The higher ongoing results reflect improved results at U.S. Franchised Electric and Gas and Commercial Power, primarily due to favorable weather, as well as improved results at Duke Energy International. These segments had combined higher earnings of 7 cents in diluted EPS on an ongoing basis and 11 cents on a reported basis.

These results were offset by a lower contribution from Crescent Resources, which changed from a wholly owned subsidiary to an effective 50-50 joint venture in September 2006.

The company reported second-quarter 2007 diluted EPS of 23 cents, or $293 million in net income, compared to 28 cents diluted EPS in second-quarter 2006, or $355 million in net income. For the first time, quarter-over-quarter comparisons of the former Cinergy operations are included in reported results. Duke Energy merged with Cinergy in April 2006.

Reported earnings for second-quarter 2007 exclude the results for the natural gas businesses that were spun off as Spectra Energy.

“We’re very pleased with the strong performance of our major business units,” said Chairman, President and Chief Executive Officer James E. Rogers. “With normal weather for the rest of the year, and our continuing focus on our operations and cost management, we expect to exceed our 2007 annual employee ongoing diluted EPS incentive target of $1.15.”

BUSINESS UNIT RESULTS

U.S. Franchised Electric and Gas

U.S. Franchised Electric and Gas (USFE&G) reported second-quarter 2007 segment EBIT from continuing operations of $452 million, compared to $351 million in the prior year. The EBIT increase over the prior year’s quarter was due primarily to favorable weather, lower purchased power and additional long-term wholesale contracts.

Second-quarter 2006 results were lower, due to an $18 million charge related to an order issued by the North Carolina Utilities Commission (NCUC) to change the calculation of bulk power marketing profits, and a $12 million charge related to community donations, also required by the NCUC for approval of the 2006 Cinergy merger.

Regional growth continued to increase USFE&G’s total customer base in second-quarter 2007. Approximately 47,000 new customers were added in the Carolinas since the second quarter of 2006, a 2 percent increase. Approximately 17,000 new customers were added in the Midwest in that same time period, a 1 percent increase.

The second-quarter 2007 EBIT increase was partially offset by higher operation and maintenance costs, driven primarily by plant outages and storm costs, and $22 million more in merger-related rate reductions than in the prior year’s quarter. Those rate reductions ended in the second quarter of 2007 with the exception of the smaller Kentucky jurisdiction, which was to be spread over five years.

Year-to-date segment EBIT from continuing operations for USFE&G was $1,026 million, compared to $710 million in 2006.

Commercial Power

For second-quarter 2007, Commercial Power reported segment EBIT of $35 million from continuing operations, compared to $20 million in the prior year’s quarter.

Commercial Power results were higher due to increased retail demand resulting largely from favorable weather, as well as higher mark-to-market gains due to economic hedges.

This contribution was partially offset by higher operation and maintenance costs mainly due to plant outages and costs associated with increased synfuel production.

Year-to-date segment EBIT from continuing operations for Commercial Power was $26 million, compared to a loss of $7 million in 2006.

2

Duke Energy International

For the second quarter of 2007, Duke Energy International (DEI), reported segment EBIT from continuing operations of approximately $97 million, compared to $24 million in last year’s second quarter.

DEI’s improved results for the quarter were driven primarily by higher margins in Latin America, and lower power purchases due to an unplanned outage last year in Peru. Last year’s second-quarter results included a $55 million impairment charge associated with an equity investment in the Campeche facility in Mexico.

Year-to-date segment EBIT from continuing operations for DEI was $191 million, compared with $110 million in 2006.

Crescent Resources

Crescent Resources reported second-quarter 2007 segment EBIT from continuing operations of $17 million, compared to $174 million in the previous year’s quarter.

Last year’s second-quarter results included an $81 million gain on the sale of properties at Potomac Yard in northern Virginia, and a $52 million gain on a land sale at Lake Keowee in South Carolina during the quarter.

Lower current-year results also reflect the September 2006 change from 100 percent ownership to an effective 50-50 joint venture, and lower residential developed-lot sales.

Year-to-date segment EBIT from continuing operations for Crescent Resources was $19 million, compared with $216 million in 2006.

Other

Other primarily includes costs associated with corporate governance, merger costs-to-achieve, and Duke Energy’s captive insurance company, Bison Insurance Co. Ltd.

Other reported a second-quarter 2007 EBIT loss from continuing operations of $66 million, compared to a loss of $151 million in the prior year’s quarter. The reduced losses were primarily due to lower merger costs, as well as lower corporate governance costs. These favorable variances were partially offset by severance costs.

Year-to-date EBIT loss from continuing operations for Other was $150 million, compared with a $204 million EBIT loss from continuing operations in 2006.

Discontinued Operations

In second-quarter 2007, Discontinued Operations had a net-of-tax loss of $10 million, compared to a second-quarter 2006 after-tax income of $159 million. The 2006 results include after-tax earnings of approximately $237 million related to Duke Energy’s natural gas businesses, which were spun off to shareholders in January 2007.

Year to date, Discontinued Operations posted a net-of-tax loss of $2 million, compared with after-tax income of $314 million in 2006.

INTEREST EXPENSE

Interest expense was $160 million for second-quarter 2007, compared to $185 million for the second quarter of 2006. The $25 million decrease was due primarily to debt reductions and refinancing activities.

Interest expense was $324 million for year-to-date 2007, compared to $288 million for year-to-date 2006. The increase was primarily due to the debt assumed as a result of the merger with Cinergy in April 2006.

INCOME TAX EXPENSE

Second-quarter 2007 income tax expense from continuing operations was $119 million, compared to $51 million in second-quarter 2006. The effective tax rate for the quarter increased to 28 percent from 21 percent in the prior year quarter. The increase was primarily due to favorable merger-related adjustments to state income taxes of approximately $40 million recorded in the prior-year quarter, partially offset by the recognition of synfuel credits of approximately $23 million recorded in the current-year quarter.

Year-to-date income tax expense from continuing operations was $224 million compared to $159 million in 2006.

NON-GAAP FINANCIAL MEASURES

The primary performance measure used by management to evaluate segment performance is segment EBIT from continuing operations, which at the segment level represents all profits from continuing operations (both operating and nonoperating), including any equity in earnings of unconsolidated affiliates, before deducting interest and taxes, and is net of the minority interest expense related to those profits. Management believes segment EBIT from continuing operations, which is the GAAP measure used to report segment results, is a good indicator of each segment’s operating performance as it represents the results of our ownership interests in continuing operations without regard to financing methods or capital structures.

Duke Energy’s management uses ongoing diluted EPS, which is a non-GAAP financial measure as it represents diluted EPS from continuing operations, adjusted for the impact of special items, as a measure to evaluate operations of the company. Special items represent certain charges and credits, which management believes will not be recurring on a regular basis. Management believes that the presentation of ongoing diluted EPS provides useful information to investors, as it allows them to more accurately compare the company’s ongoing performance across periods. Ongoing diluted EPS is also used as a basis for employee incentive bonuses.

The most directly comparable GAAP measure for ongoing diluted EPS is reported diluted EPS from continuing operations, which includes the impact of special items. Due to the forward-looking nature of ongoing diluted EPS for future periods, information to reconcile such non-GAAP financial measures to the most directly comparable GAAP financial measure is not available at this time as the company is unable to forecast any special items for future periods.

Duke Energy also uses ongoing segment (including ongoing equity earnings for Crescent Resources) and Other EBIT, including diluted-EPS-equivalent amounts, as a measure of historical and anticipated future segment and other performance. When used for future periods, ongoing segment and Other EBIT may also include any amounts that may be reported as discontinued operations. Ongoing segment and Other EBIT are non-GAAP financial measures as they represent reported segment and Other EBIT adjusted for special items. Management believes that the presentation of ongoing segment and Other EBIT provides useful information to investors, as it allows them to more accurately compare a segment’s or Other’s ongoing performance across all periods. The most directly comparable GAAP measure for ongoing segment or Other EBIT is reported segment or Other EBIT, which represents EBIT from continuing operations, including any special items. Due to the forward-looking nature of any forecasted ongoing segment or Other EBIT and any related growth rates for future periods, information to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measures is not available at this time as the company is unable to forecast any special items or any amounts that may be reported as discontinued operations for future periods.
