Vectren CEO welcomes new Board Lead Director, Jean Wojtowicz, at annual meeting as McGinley retires Evansville, Ind. - At Tuesday’s annual Vectren Corporation (NYSE: VVC) shareholders’ meeting, Chairman, President and CEO Carl Chapman recognized long-time board of directors member and lead director, Tim McGinley, who officially retired from the board today after 16 years of service to Vectren. Chapman also noted that Jean Wojtowicz became the next lead director today, upon reelection to the board. In honoring retiring board member, Tim McGinley, Chapman said, “We value the years of dedicated service and counsel he has provided our board; and on a personal note, I value the guidance he provided me during his five years as lead director. Tim’s leadership has helped shape Vectren’s strategic direction and ultimate success. We extend our sincere gratitude and best wishes to Tim in his future endeavors.” Wojtowicz, who assumes this role effective immediately, has served as a member of the company’s board since the inception of operations in April of 2000. She most recently served as chair of the board’s compensation and benefits committee and as a member of the board’s audit and risk management committee. As lead director she will serve as the chair of the nominating and corporate governance committee and will continue on the audit and risk management committee where she has been designated a financial expert. “Jean’s financial and business background, including that as a director of other public companies and her leadership skills, make her the right choice for our company. She has extensive knowledge of the company and our strategies and will serve our stakeholders well,” added Chapman. As announced in November of last year, Wojtowicz was selected to fill the lead director position as part of the company’s continuing director succession planning process that is led by the board’s nominating and corporate governance committee. This process has also resulted in the addition of two new directors in the past two years. Chapman further stated, “Just as it is essential to plan for the future with a robust management succession planning process, our entire board is of the mindset that it is equally important to make such plans for the board of directors. For that reason, we are pleased to have what we believe should be a seamless transition of board leadership.” About Vectren Vectren Corporation (NYSE: VVC) is an energy holding company headquartered in Evansville, Ind.
