Duke Energy Corporation completed an underwritten offering of 40,000,000 equity units, including 5,000,000 units sold under the underwriters’ over-allotment option, each with a stated amount of $50, for an aggregate offering size of $2,000,000,000.

Estimated net proceeds are about $1,719 million (or $1,965 million if the over-allotment option is fully exercised). Duke Energy intends to list the corporate units on the NYSE under the symbol “DUKU”.
Duke Energy Corporation reported second-quarter 2026 earnings per share (EPS) of $1.38 on a GAAP basis and $1.43 on an adjusted basis, compared with $1.25 reported and adjusted EPS in the second quarter of 2025. The $0.05 difference between reported and adjusted EPS in 2026 reflects $39 million of regulatory settlement charges at the Electric Utilities and Infrastructure segment.
Electric Utilities and Infrastructure delivered second-quarter 2026 segment income of $1,271 million reported and $1,310 million adjusted, up from $1,194 million a year earlier, driven mainly by recovery of infrastructure investments, partially offset by higher depreciation and interest expense. Gas Utilities and Infrastructure segment income was $10 million versus $6 million in 2025, while Other posted a segment loss of $204 million versus a loss of $228 million.
Consolidated operating revenues for the quarter were $7,592 million compared with $7,508 million in 2025. Net income available to common stockholders was $1,077 million versus $971 million. The consolidated reported effective tax rate rose to 12.3% from 10.6%, primarily due to lower amortization of excess deferred taxes. For the first six months of 2026, net cash provided by operating activities was $4,272 million compared with $5,040 million in 2025. Management reaffirmed 2026 adjusted EPS guidance of $6.55–$6.80 and a long-term adjusted EPS growth rate of 5%–7% through 2030 off the 2025 midpoint of $6.30.
Duke Energy Carolinas, LLC filed a Comprehensive Revenue Requirement Settlement with North Carolina stakeholders in its 2025 rate case and Performance Based Regulation application. The agreement provides for a 9.8% return on equity with a 53% equity capital structure and a retail rate base of about $25.7 billion for the historic base case. It also includes roughly $3.8 billion of capital in a multi-year rate plan with an annual refund mechanism and lowers the combined revised revenue requirement increase to $496 million, with net annualized customer rate increases ranging up to 7.4% across the plan.
The settlement framework includes evaluating a delay of Duke Energy Carolinas’ next base rate case filing until no earlier than November 1, 2028, contingent on the North Carolina Utilities Commission granting deferral of costs for certain new generating assets. Intervening parties agreed to pursue good faith settlement discussions in the Duke Energy Progress rate case to seek a substantially similar framework. The stipulations are expected to result in one-time pre-tax accounting charges of about $40 million in 2026, treated as special items and excluded from adjusted earnings.

Duke Energy Corporation created a new direct financial obligation by issuing $1,500,000,000 of 3.000% Convertible Senior Notes due 2029 in a private Rule 144A offering to qualified institutional buyers. The notes bear 3.000% fixed interest, paid semiannually, and mature on March 15, 2029 unless earlier converted or repurchased.

Duke Energy Corporation reported that an affiliate of Brookfield Super-Core Infrastructure Partners has made an indirect minority investment in Duke Energy Florida through Florida Progress, LLC. At the initial closing on March 3, 2026, Florida Progress issued 9.2% of its membership interests, raising approximately $2.8 billion.
The investment agreement calls for additional investments of $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, for total funding of about $6.0 billion. Investor ownership in Florida Progress is expected to rise to about 19.7% as these tranches are funded.
An amended and restated operating agreement for Florida Progress sets the board at eleven managers, with two nominated by the Investor and nine by Progress Energy, and grants the Investor approval rights over certain major decisions plus a right to require Progress Energy to acquire its interests under specified conditions.
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.

The agreement sets a return on equity of 9.99% with a capital structure of 53% equity/47% debt, yielding an overall rate of return of 7.4%.
