Duke Energy appoints Joyce Mullen to board effective Sept. 28

According to the company, Duke Energy filed Form 8-K with the SEC on 2026-09-25. The filing said its board had appointed Joyce Mullen as a new board member. The appointment was effective Sept. 28.

Mullen was to serve on the Audit Committee, the board group that reviews financial reporting. She was also to serve on the Operations and Nuclear Oversight Committee, the board group concerned with operations and nuclear oversight.

For private investors, the filing was a company report about an important event. In this case, it documented a governance change rather than results or guidance. That distinction helped place the news alongside later company disclosures.

The statement presented her leadership experience as relevant to its energy plans.

Ted Craver, independent chair of the Duke Energy Board of Directors, said: “Joyce is a proven leader during periods of rapid change and volatility, and her perspective will be incredibly valuable as Duke Energy navigates a pivotal time for both the company and the broader industry.” According to the company, Craver pointed to leadership during change and volatility. He described her perspective as valuable for the company and the broader industry.

The committee assignments indicated where Mullen was expected to contribute oversight. Audit work concerned financial reporting, while the other committee concerned operations and nuclear matters. Her background in leading technology businesses provided context for those governance responsibilities.
