On August 28, 2012, WellPoint, Inc. (the “Company”) announced that it is actively searching for a candidate to succeed Angela F. Braly as the President and Chief Executive Officer of the Company. The Board of Directors has established a search committee to consider both internal and external candidates, with the assistance of a search firm.

By mutual agreement between Ms. Braly and the Company, the Board has taken action such that Ms. Braly’s position as President and Chief Executive Officer of the Company has terminated. She has also stepped down from her positions as Chair and as a member of the Board of Directors. Pursuant to a separation agreement between Ms. Braly and the Company (the “Separation Agreement”), Ms. Braly will remain employed by the Company until December 31, 2012, and, subject to the execution of a waiver and release, she will receive the severance compensation and benefits described in her employment agreement and her stock options that are vested as of December 31, 2012 will continue to be exercisable pursuant to the original expiration dates.

The Company also announced that Jackie M. Ward, the Company’s Lead Director, has been named the Non-Executive Chair of the Board of Directors effective immediately.

In the interim, John Cannon, the Company’s Executive Vice President, General Counsel, Corporate Secretary and Chief Public Affairs Officer will serve as Interim President and Chief Executive Officer. Mr. Cannon, 58, has served as the Company’s Executive Vice President and General Counsel since December 2007 and he became the Company’s Secretary in February 2009. Mr. Cannon assumed responsibility for the Public Affairs department in December 2010. Before joining the Company, Mr. Cannon spent 19 years with CIGNA Corporation in a variety of roles of increasing responsibility, including as senior vice president, deputy general counsel and head of Public Affairs.
