Pursuant to Rule 425 Under the Securities Act of 1933

And Deemed Filed Pursuant to Rule 14a-12

Under the Securities Exchange Act of 1934

Subject Company: Progress Energy, Inc.

Commission File No.: 333-172899

The following Q&A was made available on the Duke Energy internal website on May 12, 2011

It’s been stated, “Progress and Duke expect to realize synergies in a number of areas,” and “Duke Energy Carolinas and Progress Energy Carolinas will continue to operate as separate utilities with separate customers, systems and rates.” Please explain.

Duke Energy Carolinas (DEC) and Progress Energy Carolinas (PEC) will continue to operate as separate utilities with separate customers, systems and rates. While there will still be distinct legal entities with their own rate structures in the Carolinas, a combined system dispatch for all resources in the Carolinas will be implemented and result in operational efficiencies and fuel savings to the benefit of the respective customers of both utilities. Other synergies will come in the areas of fuel procurement, system operation, system planning, maintenance and environmental compliance, all of which will lower costs and mitigate future rate pressures for our customers.

Duke Energy and Progress Energy also expect to achieve savings through the elimination of duplicate positions, particularly in support organizations which serve the entire enterprise. No positions will be eliminated due to the merger until the merger is completed, and reductions will be phased in over time.
