Duke Energy Reports Second Quarter 2006 Results

• Ongoing diluted earnings per share (EPS) of 43 cents versus 32 cents in prior year’s quarter; reported diluted earnings per share of 28 cents versus 32 cents in previous year’s quarter

• Gas Transmission, Field Services and Crescent post strong quarter

• Company on track to meet 2006 ongoing EPS employee incentive target

CHARLOTTE, N.C.—Duke Energy today posted ongoing diluted earnings per share (EPS) for second quarter 2006, which excludes special items and discontinued operations, of 43 cents, versus 32 cents in second quarter 2005. With the close of the Cinergy merger on April 3, second quarter 2006 represents the first quarter of combined results for the new Duke Energy.

The company reported second quarter 2006 diluted EPS of 28 cents, or $355 million in net income, compared to 32 cents per diluted share in second quarter 2005, or $307 million in net income. Revenues for second quarter 2006 were $4.04 billion, compared to $5.27 billion in the previous year. The lower revenues were driven by the deconsolidation of Duke Energy Field Services (DEFS) following the transfer of a 19.7 percent interest in DEFS from Duke Energy to ConocoPhillips in third quarter 2005. Lower revenues were partially offset by the addition of Cinergy’s operations beginning in second quarter 2006.

“Strong performances from a number of our businesses, especially Gas Transmission, Field Services and Crescent, helped the new Duke Energy deliver solid results for the quarter,” said James E. Rogers, president and chief executive officer of Duke Energy. “For the year, we remain on track to achieve our 2006 employee incentive target.

“While our businesses continued to focus on delivering strong results, we also achieved a number of important strategic milestones during the quarter,” Rogers added. “We closed the Cinergy merger and began delivering on the promise of the transaction—implementing operational improvements that will translate into positive results for our shareholders and our customers.

“In addition, we announced the decision to separate our electric and gas operations and to sell our Commercial Marketing and Trading business,” continued Rogers. “We believe the significant strategic actions taken during the quarter, along with our continued focus on results, position us well to create superior value for our shareholders.

“On top of this, the Duke Energy board endorsed an annual dividend increase of 4 cents per share,” Rogers said.

BUSINESS UNIT RESULTS

U.S. Franchised Electric & Gas

U.S. Franchised Electric & Gas (FE&G), comprised of Duke Energy Carolinas (formerly known as Duke Power) and the regulated portion of the former Cinergy utilities located in the Midwest (Duke Energy Ohio, formerly known as Cincinnati Gas & Electric; Duke Energy Indiana, formerly known as PSI Energy; and Duke Energy Kentucky, formerly known as Union Light, Heat and Power), reported second quarter 2006 EBIT from continuing operations of $351 million, compared to $274 million in the prior year. The increase over second quarter 2005 is due primarily to the addition of the former Cinergy regulated utility operations in the Midwest. EBIT from these operations of approximately $90 million is net of $10 million in rate reductions related to merger approvals in Ohio, Indiana and Kentucky.

This increase in segment EBIT was partially offset by slightly lower results at Duke Energy Carolinas which were driven by lower bulk power marketing (BPM) results, as well as a charge of approximately $15 million for community donations and rate reductions related to merger approvals in North Carolina and South Carolina.

The lower BPM results were driven by lower sales volumes during the quarter and an $18 million charge related to an order issued by the North Carolina Utilities Commission (NCUC), which requires a change to the methodology for calculating BPM profit sharing. Approximately $11 million of the recorded charge is related to 2005 BPM sales, as the NCUC’s order was retroactive to Jan.1, 2005.

Duke Energy Carolinas’ lower results were partially offset by improved weather in the region. Although weather for the quarter was below normal levels, it was an improvement over the prior year.

FE&G added about 65,000 new customers, or 1.5 percent, throughout its service territories, compared to the same period last year.

Year-to-date segment EBIT from continuing operations for U.S. Franchised Electric & Gas was $710 million, compared to $610 million in 2005.

Natural Gas Transmission

Duke Energy Gas Transmission (DEGT) reported second quarter 2006 segment EBIT of $361 million, compared to $304 million in second quarter 2005. The improvement over the previous year’s quarter was largely due to natural gas processing, primarily from the addition of the Empress assets in Canada acquired in third quarter 2005. Business expansions also contributed to the higher results, as did the favorable resolution of ad valorem tax issues and the impact of a stronger Canadian currency. These results were partially offset by higher operating costs and lower equity earnings related to interest expense.

The favorable Canadian currency impacts on DEGT’s EBIT were partially offset in Duke Energy’s consolidated net income by currency impacts on Canadian interest and taxes.

Year-to-date segment EBIT for Natural Gas Transmission was $799 million, compared to $715 million in 2005.

Field Services

The Field Services business segment, which represents Duke Energy’s 50 percent interest in Duke Energy Field Services (DEFS), reported second quarter 2006 equity earnings of $148 million, compared to $164 million of segment EBIT from continuing operations in second quarter 2005. Excluding a special item in the previous year’s quarter results, related to the settlement of 2005 de-designated hedges at Field Services, ongoing segment EBIT from continuing operations in second quarter 2005 was $142 million.

Improved ongoing results for the quarter were driven by strong commodity prices and improved NGL and gas marketing results. These were largely offset by Duke Energy’s reduced ownership interest in DEFS and lower gathering and processing volumes.

During the quarter, DEFS paid tax distributions of approximately $57 million and dividends of $83 million to Duke Energy.

Year-to-date, equity earnings for Field Services were approximately $292 million, compared to segment EBIT from continuing operations of $1.08 billion in 2005, which included pre-tax gains from the sale of DEFS’ TEPPCO GP of about $791 million, net of minority interest of about $343 million, and the sale of Duke Energy’s TEPPCO LP units of approximately $97 million.

Commercial Power

The Commercial Power business segment, which consists of non-regulated generation and marketing in the Midwest and Duke Energy Generation Services, reported segment EBIT from continuing operations of $20 million in second quarter 2006 compared with a loss of $16 million for the previous year’s quarter. Improved results over second quarter 2005 were primarily driven by the addition of Cinergy’s non-regulated businesses in the Midwest which contributed $97 million during the quarter, before the effect of approximately $48 million of net purchase accounting charges associated with the Cinergy merger, and a $16 million loss associated with the company’s synfuel facilities.

Year-to-date segment EBIT from continuing operations for Commercial Power was a loss of $7 million, compared to a loss of $34 million in 2005.

International Energy

For second quarter 2006, Duke Energy International (DEI) reported segment EBIT from continuing operations of $26 million, compared to $86 million in second quarter 2005. The lower results were driven primarily by a $55 million impairment associated with an equity investment in the Campeche facility in Mexico.

3

Absent the special item noted above, ongoing EBIT for second quarter 2006 was $81 million, compared to $86 million in the previous year’s quarter. Lower ongoing results for the quarter were primarily driven by increased power purchases as a result of an unplanned outage in Peru and unfavorable hydrology in Peru and Brazil. These results were partially offset by favorable currency impacts—mainly in Brazil.

Year-to-date segment EBIT from continuing operations for International Energy was $113 million, compared with $154 million in 2005.

Crescent Resources

Crescent Resources reported second quarter 2006 segment EBIT from continuing operations of $174 million, compared to $38 million in the previous year’s quarter. Improved results compared to last year’s second quarter were driven primarily by 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.

Year-to-date segment EBIT from continuing operations for Crescent Resources was $216 million, compared with $90 million in 2005.

Other

Other primarily includes the cost of corporate governance, costs-to-achieve related to the Cinergy merger, costs-to-achieve associated with the anticipated spin-off of Duke Energy’s natural gas businesses to shareholders, Duke Energy’s captive insurance company, Bison Insurance Co. Limited, and de-designated hedges resulting from the decision in 2005 to transfer a 19.7 percent interest in DEFS to ConocoPhillips.

Other reported an EBIT loss of $174 million in second quarter 2006, compared to a loss of $102 million in second quarter 2005, which included a mark-to-market gain of $7 million related to 2005 de-designated hedges associated with Field Services.

The additional losses in second quarter 2006 were generated by special items for the quarter due primarily to $74 million in costs-to-achieve related to the Cinergy merger, consisting primarily of severance, and $8 million in costs-to-achieve related to the anticipated spin-off of Duke Energy’s natural gas businesses.

Results were offset slightly by decreased liabilities associated with mutual insurance companies.

Absent the special items noted above, ongoing EBIT for second quarter 2006 was a loss of $92 million, compared to an ongoing loss of $109 million in the previous year’s quarter.

Year-to-date EBIT loss from continuing operations for Other was $232 million, compared with a $286 million EBIT loss from continuing operations in 2005.

Discontinued Operations

In second quarter 2006, Discontinued Operations had a net-of-tax loss of $80 million, compared to a second quarter 2005 net-of-tax loss of $19 million. Lower results were driven primarily by an approximate $50 million net-of-tax loss on the sale of the final remaining contracts at Duke Energy North America (DENA).

Year-to-date, Discontinued Operations posted a net-of-tax loss of $208 million, compared with a net-of-tax loss of $11 million in 2005.

INTEREST EXPENSE

Interest expense was $339 million for second quarter 2006, compared to $295 million for the second quarter of 2005. This increase was primarily due to the acquisition of Cinergy, partially offset by the transfer of a 19.7 percent interest in DEFS from Duke Energy to ConocoPhillips in third quarter 2005, which resulted in the deconsolidation of this investment by Duke Energy.

Interest expense was $589 million for year-to-date 2006, compared to $585 million for year-to-date 2005. Interest increased primarily due to the impact of the acquisition of Cinergy which was offset by the deconsolidation of DEFS.

INCOME TAX

Second quarter 2006 income tax expenses from continuing operations were $175 million, compared to $157 million in second quarter 2005. For the quarter, Duke Energy’s net effective tax rate was approximately 29 percent resulting from merger-related adjustments to state income taxes during the quarter of approximately $40 million.

Year-to-date income tax expense from continuing operations was $433 million, compared to $608 million in 2005.

ADDITIONAL INFORMATION

Additional information about EPS reconciliation data can be obtained at Duke Energy’s second quarter 2006 earnings information Web site at: www.duke-energy.com/investors/.

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 non-operating), 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 plus any discontinued operations from its Crescent Resources real estate unit, 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. In 2006, ongoing diluted EPS, adjusted for the impacts of purchase accounting related to the Cinergy merger, will be used as the 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 Field Services) and Other EBIT as a measure of historical and anticipated future segment 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 may 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 forecasted ongoing segment and Other EBIT and 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.
