Duke Energy reports second-quarter 2025 financial results

▪Second-quarter 2025 reported and adjusted EPS of $1.25

▪Strong first half performance puts the company on track to deliver full year results within guidance range

▪Transaction proceeds support material strengthening of company’s credit profile and higher capital deployment at Duke Energy Florida

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced second-quarter 2025 reported EPS, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.25. This is compared to reported EPS of $1.13 and adjusted EPS of $1.18 for the second quarter of 2024. Adjusted EPS excludes the impact of certain items that are included in reported EPS.

Higher second-quarter 2025 adjusted results were driven by the implementation of new rates and riders, partially offset by higher O&M expenses and interest expense.

G1The company is reaffirming its 2025 adjusted EPS guidance range of $6.17 to $6.42 and G2long-term adjusted EPS growth rate of 5% to 7% through 2029 off the 2025 midpoint of $6.30. Management does not forecast reported GAAP EPS and related long-term growth rates.

“We’ve had a strong start to the year, executing on our strategic priorities of advancing large-scale economic development projects, securing industry-leading regulatory and legislative outcomes, and strengthening the balance sheet,” said Harry Sideris, Duke Energy president and chief executive officer. “To position the company for the significant growth ahead, we recently announced two strategic transactions – an equity investment in Duke Energy Florida and the sale of our Piedmont Tennessee business. These efficient funding sources at compelling valuations materially strengthen our credit profile and help fund the increasing investments needed to meet unprecedented growth over the next decade.”

Duke Energy News Release 2

Business segment results

In addition to the following summary of second-quarter 2025 business segment performance, comprehensive tables with detailed EPS drivers for the second quarter compared to prior year are provided at the end of this news release.

The discussion below of second-quarter results includes both GAAP segment income and adjusted segment income, which is a non-GAAP financial measure. The tables at the end of this news release present a full reconciliation of GAAP reported results to adjusted results.

Electric Utilities and Infrastructure

On a reported basis, Electric Utilities and Infrastructure recognized second-quarter 2025 segment income of $1,194 million, compared to segment income of $1,090 million in the second quarter of 2024.

On an adjusted basis, Electric Utilities and Infrastructure recognized second-quarter 2025 segment income of $1,194 million, compared to segment income of $1,115 million in the second quarter of 2024. This represents an increase of $0.10 per share, excluding share dilution of $0.01 per share. Higher quarterly results were primarily due to the implementation of new rates, partially offset by higher O&M expense and interest expense.

Gas Utilities and Infrastructure

On a reported and adjusted basis, Gas Utilities and Infrastructure recognized second-quarter 2025 segment income of $6 million, compared to reported and adjusted segment income of $6 million in the second quarter of 2024. Flat quarterly results were primarily due to growth from rate increases and riders, offset by higher O&M expenses and depreciation on a growing asset base.

Other

Other primarily includes interest expense on holding company debt, other unallocated corporate costs and results from Duke Energy’s captive insurance company.

On a reported and adjusted basis, Other recognized a second-quarter 2025 segment loss of $228 million, compared to reported and adjusted segment loss of $200 million in the second quarter of 2024. This represents a decrease of $0.02 per share. Lower quarterly results were primarily due to higher interest expense.

Duke Energy News Release 3

Effective tax rate

Duke Energy's consolidated reported effective tax rate for the second quarter of 2025 was 10.6% compared to 13.1% in the second quarter of 2024. The decrease in the effective tax rate was primarily due to an increase in the amortization of income tax credits and lower state tax expense.

Duke Energy's consolidated adjusted effective tax rate was 10.6% for the second quarter of 2025 compared to 13.4% in the second quarter of 2024. The decrease in the adjusted effective tax rate was primarily due to an increase in the amortization of income tax credits and lower state tax expense.

The tables at the end of this news release present a reconciliation of the reported effective tax rate to the adjusted effective tax rate.

Earnings conference call for analysts

An earnings conference call for analysts is scheduled at 10 a.m. ET today to discuss second-quarter 2025 financial results and other business and financial updates. The conference call will be hosted by Harry Sideris, president and chief executive officer, and Brian Savoy, executive vice president and chief financial officer.

Duke Energy News Release 4

Non-GAAP financial measures

Management evaluates financial performance in part based on non-GAAP financial measures, including adjusted earnings, adjusted EPS and adjusted effective tax rate. Adjusted earnings and adjusted EPS represent income (loss) from continuing operations available to Duke Energy Corporation common stockholders in dollar and basic per share amounts, adjusted for the dollar and per share impact of special items. The adjusted effective tax rate is calculated using pretax earnings and income tax expense, both adjusted to include the impact of noncontrolling interests and preferred dividends and to exclude the impact of special items. Special items represent certain charges and credits, which management believes are not indicative of Duke Energy's ongoing performance.

Special items included within the financial statement periods presented, which management does not believe are reflective of ongoing costs, are described below:

•Regulatory matters primarily represents impairment charges related to the 2024 Duke Energy Carolinas' South Carolina rate case order.

Management uses these non-GAAP financial measures for planning, forecasting, and to report financial results to the Board of Directors, employees, and stockholders, as well as analysts and investors. The most directly comparable GAAP measures for adjusted earnings, adjusted EPS and the adjusted effective tax rate are Net Income (Loss) Available to Duke Energy Corporation common stockholders (GAAP reported earnings (loss)), Basic earnings (loss) per share Available to Duke Energy Corporation common stockholders (GAAP reported earnings (loss) per share), and the reported effective tax rate, respectively.

Due to the forward-looking nature of forecasted adjusted EPS and related growth rates, the information to reconcile those amounts to the most directly comparable GAAP financial measure is not available, as management is unable to project special items, such as legal settlements, impacts of regulatory orders or asset impairments, for future periods.

Management evaluates segment performance based on segment income and other net loss. Segment income and other net loss are defined as income (loss) from continuing operations net of income attributable to noncontrolling interests and preferred stock dividends. Segment income and other net loss include intercompany revenues and expenses that are eliminated in the Condensed Consolidated Financial Statements. Management also uses adjusted segment income and adjusted other net loss as measures of historical and anticipated future segment performance. Adjusted segment income and adjusted other net loss are non-GAAP financial measures, as they represent segment income and other net loss adjusted for special items, as discussed above. Management believes the presentation of adjusted segment income and adjusted other net loss provide useful information to investors, as they provide additional relevant comparison of a segment’s or Other's performance across periods. The most directly comparable GAAP measures for adjusted segment income and adjusted other net loss are segment income and other net loss.

Duke Energy News Release 5

Due to the forward-looking nature of forecasted adjusted segment income and forecasted adjusted other net loss and related growth rates, the information to reconcile these amounts to the most directly comparable GAAP financial measures are not available, as management is unable to project special items, as discussed above.

Duke Energy’s adjusted earnings, adjusted EPS, adjusted effective tax rate, adjusted segment income, and adjusted other net loss may not be comparable to similarly titled measures of another company because other companies may not calculate the measures in the same manner.

(a) Piedmont has a margin decoupling mechanism in North Carolina, weather normalization mechanisms in South Carolina and Tennessee and fixed-price contracts with most power generation customers that significantly eliminate the impact of throughput changes on earnings. Duke Energy Ohio's rate design also serves to offset this impact.

Underlines use the same word lists the scores use. AI, recession and tariffs follow Palanor’s word counter, so those counts match it exactly on the same text. Layoffs and buybacks use the terms the model was given. The model’s count is an estimate by meaning, not by string, so it can differ from the underlines.
