Duke Energy reports first-quarter 2025 financial results

▪First-quarter 2025 reported and adjusted EPS of $1.76

▪Strong start to the year, driven by revenue growth across Electric and Gas utilities

▪Company advancing new generation to serve growing energy demand

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced first-quarter 2025 reported EPS, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.76. This is compared to reported and adjusted EPS of $1.44 for the first quarter of 2024. Adjusted EPS excludes the impact of certain items that are included in reported EPS.

Higher first-quarter 2025 adjusted results were driven by higher retail sales volumes and implementation of new rates and riders as well as improved weather, partially offset by higher interest expense and O&M expenses.

The company is reaffirming its 2025 adjusted EPS guidance range of $6.17 to $6.42 and long-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.

“I am incredibly proud of our performance in the first quarter, which is a result of the constructive regulatory outcomes the team has delivered over the last several years,” said Harry Sideris, Duke Energy president and chief executive officer. "The fundamentals of the company are stronger than ever, positioning us extraordinarily well to meet our customers' growing and evolving energy demands – now and into the future.”

Business segment results

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

The discussion below of first-quarter results includes both GAAP segment income and adjusted segment income, which is a non-GAAP financial measure. For the quarters ended March 31, 2025, and 2024, reported segment income and adjusted segment income were equal for each of Duke Energy's business segments and Other. The tables at the end of this news release present a full reconciliation of GAAP reported results to adjusted results.

Electric Utilities and Infrastructure

Electric Utilities and Infrastructure recognized first-quarter 2025 segment income of $1,276 million, compared to segment income of $1,021 million in the first quarter of 2024. This represents an increase of $0.33 per share. Higher quarterly results were primarily due to higher retail sales volumes, improved weather and implementation of new rates, partially offset by higher interest expense, O&M expense and depreciation on a growing asset base.

Gas Utilities and Infrastructure

Gas Utilities and Infrastructure recognized first-quarter 2025 segment income of $349 million, compared to segment income of $284 million in the first quarter of 2024. This represents an increase of $0.08 per share. Higher quarterly results were primarily due to growth from rate increases, partially offset by higher 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.

Other recognized a first-quarter 2025 segment loss of $260 million, compared to segment loss of $203 million in the first quarter of 2024. This represents a decrease of $0.08 per share. Lower quarterly results were primarily due to higher interest expense and lower returns on investments.

Effective tax rate

Duke Energy's consolidated reported effective tax rate for the first quarter of 2025 was 12.1% compared to 13.4% in the first quarter of 2024. The decrease in the effective tax rate was primarily due to an increase in the amortization of income tax credits.

Duke Energy's consolidated adjusted effective tax rate was 12.2% for the first quarter of 2025 compared to 13.7% in the first 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 a decrease in preferred dividends.

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

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 include certain charges and credits, which management believes are not indicative of Duke Energy's ongoing performance.

Management uses these non-GAAP financial measures for planning and forecasting, and for reporting financial results to the Board of Directors, employees, stockholders, 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.

There were no special items included in the periods presented.

Duke Energy News Release    4

Due to the forward-looking nature of any forecasted adjusted earnings guidance, information to reconcile this non-GAAP financial measure to the most directly comparable GAAP financial measure is not available at this time, as management is unable to project all special items for future periods (such as legal settlements, the impact of regulatory orders or asset impairments).

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 are based upon 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 provides useful information to investors, as they provide an additional relevant comparison of a segment’s or Other's performance across periods. The most directly comparable GAAP measure for adjusted segment income or adjusted other net loss is segment income and other net loss.

Due to the forward-looking nature of any forecasted adjusted segment income or adjusted other net loss and any related growth rates for future periods, information to reconcile these non-GAAP financial measures to the most directly comparable GAAP financial measures is not available at this time, as management is unable to forecast all special items, as discussed above.

Duke Energy’s adjusted earnings, adjusted EPS, 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.
