What Does the Merger Mean for You?

As with any major change, you probably have questions about the transition and how it might affect you personally. We won’t know the answers to many of your questions until the integration team is much further in its work. The executives leading that effort are committed to keeping employees informed as decisions are made.

Integration team’s work

The integration team, made up of representatives from both utilities, will be working over the next year to combine the organizations. A.R. Mullinax, senior vice president and chief information officer at Duke, and Paula Sims, senior vice president - corporate development and improvement at Progress, will co-lead this integration effort. The integration team will be charged with developing a plan to consolidate functions where it makes financial and operational sense and manage the transition. Once that plan is developed, we will have a better idea of impacts on the workforce. That comprehensive analysis performed will drive organizational decisions and staffing levels. The multi-year transition period also will help to further minimize reductions through attrition, retirements and managing of vacancies.

Impact on employees

We anticipate there will be job reductions at both companies as we merge operations in the years ahead. At this point, we do not have a predetermined number or goal. We will work to minimize the number of reductions by taking advantage of savings in other areas first (including fuel efficiencies and joint dispatch in the Carolinas).

We currently anticipate that no positions will be eliminated until the merger is approved, which is expected to take about a year. And reductions will be phased in over several years.

In the future when positions are eliminated, the companies will provide severance benefits for eligible employees who are not placed in the new organization.

Opportunities

It is important to remember that the larger, stronger company created from the combination will provide new opportunities for employees to grow in their careers.

Committed to bringing you more information

An employee meeting hosted by Duke Energy CEO Jim Rogers and Progress Energy CEO Bill Johnson will be held from 2 to 3 p.m. Thursday, Jan. 13, at the Knight Theater in downtown Charlotte. Locations outside of Charlotte will be able to join in. Please look for details on the Portal.

Don’t get distracted

“The merger will mean change for all of us and it’s easy to get distracted by that,” said A.R. Mullinax, who’s leading the integration efforts. “While the merger will form the largest utility in


the nation and present numerous opportunities, I ask that all employees remain focused on achieving their current objectives and meeting the needs of our customers.”

Employees should also keep in mind that the two companies will continue to operate separately until the close of the transaction, he added.

If you have questions, please send them to: integration@duke-energy.com. We’ll work with the Integration Team to address questions that are top-of-mind for our employees. Remember, answers to many questions may not be available until the team is further into its work. We’ll keep you posted as details become firm.
