Duke Energy Corporation appointed Joyce Mullen to its board, effective September 28, 2026, for an initial term ending at the 2027 Annual Meeting of Shareholders. She will join the Audit Committee and the Operations and Nuclear Oversight Committee. The board determined she is independent under the company’s standards, New York Stock Exchange listing standards, and SEC rules.
Mullen retired as president and chief executive officer of Insight Enterprises in April 2026 and continues advising its leadership as executive vice president of strategic development.
