Duke Energy Corporation, Progress Energy and Florida Progress have cleared the final regulatory hurdle for a major minority investment in Florida Progress. The U.S. Nuclear Regulatory Commission determined that the transaction does not involve a transfer of control of any NRC license, satisfying the last condition to the first closing under a previously signed Investment Agreement with Peninsula Power Holdings L.P., an affiliate of Brookfield Super-Core Infrastructure Partners.
Under this agreement, the investor will provide an aggregate $6 billion to Florida Progress in exchange for newly issued membership interests, ultimately owning up to 19.7% of the company. The first closing is scheduled for March 3, 2026, when the investor will pay $2.8 billion for a 9.2% stake. Additional closings will add $200 million by December 31, 2026, $500 million by June 30, 2027, $1.5 billion by December 31, 2027, and $1 billion by June 30, 2028, completing the staged investment.

Duke Energy Corporation reported strong 2025 results and updated its long-term outlook. Full-year reported and adjusted EPS were $6.31, up from reported EPS of $5.71 and adjusted EPS of $5.90 in 2024, with no special-item difference in 2025.
Management cited earnings growth from recovering infrastructure investments and customer growth, partly offset by higher operations and maintenance, interest expense, property taxes and depreciation on a larger asset base. Fourth-quarter 2025 adjusted EPS was $1.50, down from $1.66 a year earlier, reflecting higher costs and a higher effective tax rate.
The company outlined a $103 billion five-year capital plan that it expects will drive about 9.6% earnings base growth through 2030. It introduced 2026 adjusted EPS guidance of $6.55 to $6.80 and extended its targeted long-term adjusted EPS growth rate of 5% to 7% through 2030, aiming to earn in the top half of that range beginning in 2028.
