Duke Energy Reports Third-Quarter 2008 Results

• Adjusted diluted earnings per share (EPS) was 33 cents, compared with 45 cents for the third quarter 2007

^¡ Adverse impact of 8 cents to adjusted diluted EPS due to reduced revenues from significantly milder weather and Midwest storm costs

• Reported diluted EPS was 17 cents vs. 48 cents for the prior-year quarter; non-cash items adversely impacted reported earnings by 15 cents

• Following a non-cash impairment charge in the third quarter, Duke now has a zero book basis in Crescent, limiting further exposure to the real estate market

• The Company’s liquidity position remains strong

CHARLOTTE, N.C. – Duke Energy today reported adjusted diluted earnings per share (EPS) of 33 cents for the third-quarter 2008, compared with 45 cents for the same period last year.

Third-quarter 2008 reported diluted EPS was 17 cents vs. 48 cents in third-quarter 2007.

“We are disappointed in the third quarter results, but our strong performance earlier in the year will help mitigate the impact of these results on our year-end performance,” said Chairman, President and Chief Executive Officer James E. Rogers. “Although we don’t believe we will be able to achieve our 2008 employee incentive target of $1.27 of adjusted diluted earnings per share by year’s end – particularly in this economy – we are only about 5 cents off of where we expected to be at the end of the third quarter.”

Third-quarter 2008 adjusted results were adversely affected by milder weather in Duke Energy’s service territories, expenses related to the worst storm-related outages ever recorded in the Midwest, timing of recovery of fuel and purchased power costs under the RSP in Ohio, and generally declining economic conditions.

“Despite a recessionary economy and tight credit markets, our energy businesses remain solid and our liquidity position is excellent. We have the operational and financial flexibility to respond to a recessionary economy or continued turmoil in the credit markets,” Rogers said.

Starting in the first-quarter 2008, Duke Energy began presenting adjusted earnings, which excludes the impacts of special items and discontinued operations, as well as the mark-to-market impacts of economic hedges in the Commercial Power segment. Prior to the first-quarter 2008, Duke Energy presented ongoing earnings, which excluded the impacts of special items and discontinued operations. For comparative purposes, ongoing earnings for prior periods have been revised to present results for all periods on the same adjusted earnings basis.

BUSINESS UNIT RESULTS (ON A REPORTED BASIS)

U.S. Franchised Electric and Gas (USFE&G)

USFE&G reported third-quarter 2008 segment EBIT from continuing operations of $726 million, compared to $760 million in the third quarter 2007.

USFE&G results decreased due primarily to milder weather and unfavorable operation and maintenance expenses driven by storm costs in the Midwest. During the third quarter 2007, USFE&G experienced record-setting weather in both the Carolinas and Midwest.

These negative impacts were partially offset by higher Allowance for Funds Used During Construction (AFUDC), higher rates in the Midwest as a result of recovery of qualifying pollution control costs in Indiana and rate increases in Ohio, as well as higher results from sales to wholesale customers.

Overall, USFE&G’s customer base continues to grow, although the economy is beginning to cause a decline in energy usage.

Year-to-date segment EBIT from continuing operations for USFE&G was $1,866 million, compared to $1,786 million in 2007.

Commercial Power

Commercial Power reported a third-quarter 2008 segment EBIT loss from continuing operations of $108 million, compared to $163 million positive EBIT in the third quarter 2007.

Commercial Power results decreased due primarily to mark-to-market losses on economic hedges driven by sharply declining commodity prices, an impairment of emission allowances resulting from the invalidation in federal court of the Clean Air Interstate Rule, the timing of recovery of fuel and purchased power costs under the Ohio RSP, and milder weather. The decrease was partially offset by lower purchase accounting and operating and maintenance expenses.

Year-to-date segment EBIT from continuing operations for Commercial Power was $273 million, compared to $240 million in 2007.

2

Duke Energy International (DEI)

Duke Energy International (DEI) reported third-quarter 2008 segment EBIT from continuing operations of approximately $77 million, compared to $92 million in the third quarter 2007.

DEI’s lower results for the quarter were driven primarily by unfavorable hydrology and lower prices in Peru and lower results in Central America, partially offset by increased demand in Brazil, favorable average foreign exchange rates and higher results at National Methanol.

Year-to-date segment EBIT from continuing operations for DEI was $307 million, compared to $283 million in 2007.

Crescent Resources

Duke Energy’s ownership interest in Crescent Resources reported a $124 million equity earnings loss for the third quarter 2008, compared to $10 million in positive equity earnings in the third quarter 2007. Lower current year results reflect $114 million in asset impairments primarily related to residential properties as Crescent continued to assess projects in troubled real estate markets, consistent with its revised business strategy. This strategy involves accelerating property sales, which is necessitated by the June 2008 restructuring of the terms of its long-term debt obligations.

Year-to-date, Duke Energy’s ownership interest in Crescent Resources reported a $230 million equity earnings loss, compared to $29 million in positive equity earnings in 2007.

As a result of these write-downs, Duke Energy has a zero basis investment in Crescent as of September 30, 2008.

Other

Other primarily includes costs associated with corporate governance, costs-to-achieve the Cinergy merger and Duke Energy’s captive insurance company.

Other reported a third-quarter 2008 net expense from continuing operations of $71 million, compared to $44 million in the third quarter 2007. The increase was due primarily to a non-recurring settlement adjustment in the prior year quarter.

Year-to-date net expense from continuing operations for Other was $230 million, compared to $194 million in 2007.

INTEREST EXPENSE

Interest expense in third quarter 2008 was $176 million, compared to $177 million in third quarter 2007.

Year-to-date interest expense was $552 million, compared to $499 million in 2007.

INCOME TAX EXPENSE

Income tax expense from continuing operations in third quarter 2008 was $132 million, compared to $304 million in third quarter 2007. The effective tax rate for the third quarter 2008 increased to 38 percent from 35 percent in third quarter 2007. The decrease in income tax expense from continuing operations was primarily due to a decrease in taxable income.

Year-to-date income tax expense from continuing operations was $521 million, compared to $595 million in 2007. The effective tax rate for year-to-date 2008 was 34 percent, compared to 33 percent in 2007.

Discontinued Operations

In the third quarter of 2008, Discontinued Operations had an after-tax loss of $1 million, compared to a $34 million after-tax gain in the third quarter 2007. The variance is primarily due to the presentation of the third-quarter 2007 synfuel operations as discontinued operations.

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 Duke Energy’s ownership interests in continuing operations without regard to financing methods or capital structures.

3

Duke Energy’s management uses adjusted diluted EPS, which is a non-GAAP financial measure as it represents diluted EPS from continuing operations, adjusted for the per-share impact of special items and the mark-to-market impacts of economic hedges in the Commercial Power segment, 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. Mark-to-market adjustments reflect the mark-to-market impact of derivative contracts, which is recognized in GAAP earnings immediately as such derivative contracts do not qualify for hedge accounting, used in Duke Energy’s hedging of a portion of the economic value of its generation assets in the Commercial Power segment. The economic value of the generation assets is subject to fluctuations in fair value due to market price volatility of the input and output commodities (e.g. coal, power) and, as such, the economic hedging involves both purchases and sales of those input and output commodities related to the generation assets. Because the operations of the generation assets are accounted for under the accrual method, management believes that excluding the impact of mark-to-market changes of the economic hedge contracts from adjusted earnings until settlement better matches the financial impacts of the hedge contract with the portion of the economic value of the underlying hedged asset. Management believes that the presentation of adjusted diluted EPS provides useful information to investors, as it allows them to more accurately compare the company’s performance across periods. Adjusted diluted EPS is also used as a basis for employee incentive bonuses.

Management prepares its annual forecast of adjusted diluted EPS as a basis for employee incentive bonuses based in part on normalized weather patterns. In the third quarter of 2008, the Company incurred approximately $50 million in restoration costs related to the worst storm-related outages ever recorded in the Midwest. Also, in the third quarter of 2007, record setting above-normal weather was experienced in the Carolinas and the Midwest. The milder weather in the third quarter of 2008 had the effect of an approximate $120 million decrease in non-fuel operating revenues. These specific items resulted in a decline in adjusted diluted EPS in the third quarter of 2008 compared to the third quarter of 2007 of approximately 8 cents. Additional revenue and expense items that might have been attributable to the above-normal weather conditions in the third quarter of 2007, such as increased short-term incentive expense, are not included in the calculation of the 8 cents diluted EPS impact. In the current quarter, given the record-setting nature of the aforementioned weather occurrences, management believes the presentation of the diluted EPS impact of these specific items provides useful supplemental information to investors, as it allows them to more accurately compare the company’s performance on a weather normalized basis.

The most directly comparable GAAP measure for adjusted diluted EPS is reported diluted EPS from continuing operations, which includes the impact of special items and the mark-to-market impacts of economic hedges in the Commercial Power segment.

Due to the forward-looking nature of adjusted diluted EPS for future periods, information to reconcile such 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 special items and the mark-to-market impacts of economic hedges in the Commercial Power segment for future periods.

Duke Energy also uses adjusted segment EBIT (including adjusted equity earnings for Crescent Resources) and Other net expenses as a measure of historical and anticipated future segment and other performance. When used for future periods, adjusted segment EBIT and Other net expenses may also include any amounts that may be reported as discontinued operations. Adjusted segment EBIT and Other net expenses are non-GAAP financial measures, as they represent reported segment EBIT and Other net expenses adjusted for special items and the mark-to-market impacts of economic hedges in the Commercial Power segment. Management believes that the presentation of adjusted segment EBIT and Other net expenses provides useful information to investors, as it allows them to more accurately compare a segment’s or Other’s ongoing performance across periods. The most directly comparable GAAP measure for adjusted segment EBIT or Other net expenses is reported segment EBIT or Other net expenses, which represents segment EBIT and Other net expenses from continuing operations, including any special items and the mark-to-market impacts of economic hedges in the Commercial Power segment. Due to the forward-looking nature of any forecasted adjusted segment EBIT or Other net expenses 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 special items, the mark-to-market impacts of economic hedges in the Commercial Power segment, or any amounts that may be reported as discontinued operations for future periods.

* Represents the mark-to-market impact of derivative contracts, which is recognized in earnings immediately as such derivative contracts do not qualify for hedge accounting, used in Duke Energy’s hedging of a portion of the economic value of its generation assets in the Commercial Power segment. The economic value of the generation assets is subject to fluctuations in fair value due to market price volatility of the input and output commodities (e.g. coal, power) and, as such, the economic hedging involves both purchases and sales of those input and output commodities related to the generation assets. Because the operations of the generation assets are accounted for under the accrual method, management believes that excluding the impact of mark-to-market changes of the economic hedge contracts from adjusted earnings until settlement better matches the financial impacts of the hedge contract with the portion of the economic value of the underlying hedged asset. Management believes that the presentation of adjusted diluted EPS provides useful information to investors, as it allows them to more accurately compare the company’s performance across periods.

Notes:

1) Management prepares its annual forecast of adjusted diluted EPS as a basis for employee incentive bonuses based in part on normalized weather patterns. In the third quarter of 2008, the Company incurred approximately $50 million in restoration costs related to the worst storm-related outages ever recorded in the Midwest. Also, in the third quarter of 2007, record setting above-normal weather was experienced in the Carolinas and the Midwest. The milder weather in the third quarter of 2008 had the effect of an approximate $120 million decrease in non-fuel operating revenues. These specific items resulted in a decline in adjusted diluted EPS in the third quarter of 2008 compared to the third quarter of 2007 of approximately 8 cents. Additional revenue and expense items that might have been attributable to the above-normal weather conditions in the third quarter of 2007, such as increased short-term incentive expense, are not included in the calculation of the 8 cents diluted EPS impact.

The diluted EPS impact of these specific items is a non-GAAP financial measure. The most directly comparable GAAP measure for the diluted EPS impact of the aforementioned specific items is reported diluted EPS from continuing operations, which is discussed further below. In the current quarter, given the record-setting nature of the aforementioned weather occurrences, management believes the presentation of the diluted EPS impact of these specific items provides useful supplemental information to investors, as it allows them to more accurately compare the company’s performance on a weather normalized basis.

2) Reported diluted EPS for the third quarter of 2008 was $0.17 as compared to $0.48 for the third quarter of 2007. Adjusted diluted EPS for the third quarter of 2008 was $0.33 as compared to $0.45 for the third quarter of 2007. The aforementioned weather-related EPS impacts are reflected within these reported and adjusted results for the third quarter of 2008 and 2007. The most directly comparable GAAP measure for adjusted diluted EPS and the diluted EPS impact of the aforementioned specific items is reported diluted EPS from continuing operations. A reconciliation of adjusted diluted EPS to reported diluted EPS is included with these materials.
