Duke Energy and Progress Energy to Merge

• Diversified Generation Portfolio in Six Regulated Service Territories

• Transaction Expected to be Accretive to Adjusted Diluted Earnings in First Year

CHARLOTTE, N.C. and RALEIGH, N.C. – Duke Energy (NYSE: DUK) and Progress Energy, Inc. (NYSE: PGN) announced today that both companies’ boards of directors have unanimously approved a definitive merger agreement to combine the two companies in a stock-for-stock transaction. The combined company, to be called Duke Energy, will be the country’s largest utility, with:

• Approximately 57 gigawatts of domestic generating capacity from a diversified mix of coal, nuclear, natural gas, oil and renewable resources

• The largest regulated nuclear fleet in the country.

“Our industry is entering a building phase where we must invest in an array of new technologies to reduce our environmental footprints and become more efficient,” said Jim Rogers, chairman, president and chief executive officer of Duke Energy. “By merging our companies, we can do that more economically for our customers, improve shareholder value and continue to grow.

“Combining Duke Energy and Progress Energy creates a utility with greater financial strength and enhanced ability to meet our challenges head-on,” Rogers continued.

“This combination of two outstanding companies is a natural fit,” said Bill Johnson, chairman, president and chief executive officer of Progress Energy. “It makes clear strategic sense and creates exceptional value for our shareholders. Together, we can leverage our best practices to achieve even higher levels of safety, operational excellence and customer satisfaction, and save money for customers by combining our fuel purchasing power and the dispatch of our generating plants.

“This merger also provides predictable earnings and cash flows to support our dividend payments to shareholders,” Johnson added.

Terms

Under the merger agreement, Progress Energy’s shareholders will receive 2.6125 shares of common stock of Duke Energy in exchange for each share of Progress Energy common stock. Based on Duke Energy’s closing share price on Jan. 7, 2011, Progress Energy shareholders would receive a value of $46.48 per share, or $13.7 billion in total equity value.

Duke Energy also will assume approximately $12.2 billion in Progress Energy net debt. The transaction price represents a 7.1 percent premium to the unaffected closing stock price of Progress Energy on Jan. 5, 2011, and a 3.9 percent premium to the closing stock price of Progress Energy on Jan. 7, 2011.

The transaction price also represents a 6.6 percent premium to the average closing stock price of Progress Energy over the last 20 trading days ending Jan. 5, 2011, and a 6.4 percent premium over the last 20 trading days ending Jan. 7, 2011.

Following completion of the merger, officials anticipate Duke Energy shareholders will own approximately 63 percent of the combined company and Progress Energy shareholders will own approximately 37 percent on a fully diluted basis.

The combination is anticipated to be accretive to Duke Energy’s adjusted earnings in the first year after closing.

Based on Duke Energy’s current quarterly cash dividend of 24.5 cents per common share, Progress Energy shareholders would receive an approximate 3 percent dividend increase.

Duke Energy expects to effect a reverse stock split immediately prior to closing, and, as a result, the exchange ratio will be appropriately adjusted at that time to reflect the reverse split.

Non-GAAP Financial Measures

Adjusted Earnings per Share Accretion in Year One

This news release includes a discussion of Duke Energy’s assumption that the merger transaction is anticipated to be accretive in the first year after closing, based upon adjusted diluted EPS.

This accretion assumption is a non-GAAP financial measure as it is based upon diluted EPS from continuing operations attributable to Duke Energy Corporation shareholders, adjusted for the per-share impact of special items and the mark-to-market impacts of economic hedges in the Commercial Power segment.

Special items represent certain charges and credits, which management believes will not be recurring on a regular basis, although it is reasonably possible such charges and credits could recur. 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 or regulatory accounting treatment, 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 provides them an additional relevant comparison of the company’s performance across periods. Adjusted diluted EPS is also used as a basis for employee incentive bonuses.

The most directly comparable GAAP measure for adjusted diluted EPS is reported diluted EPS from continuing operations attributable to Duke Energy Corporation common shareholders, which includes the impact of special items (including costs-to-achieve the merger) and the mark-to-market impacts of economic hedges in the Commercial Power segment. On a reported diluted EPS basis, this transaction is not anticipated to be accretive due to the level of costs-to-achieve the merger. Due to the forward-looking nature of this non-GAAP financial measure for future periods, information to reconcile it to the most directly comparable GAAP financial measure is not available at this time, as management is unable to project special items or mark-to-market adjustments for future periods.
