**Duke Energy reports fourth-quarter and full-year 2025 financial results**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ 2025 reported and adjusted EPS of $6.31, closing the year above the guidance midpoint**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ $103 billion five-year capital plan drives 9.6% earnings base growth through 2030**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ Company extends long-term adjusted EPS growth rate of 5% to 7% though 2030, with confidence to earn in the top half of the range beginning in 2028**

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced 2025 full-year reported EPS, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $6.31. This is compared to reported and adjusted EPS of $5.71 and $5.90, respectively, for the full-year 2024.

Adjusted EPS excludes the impact of certain items that are included in reported EPS. There is no difference between 2025 GAAP reported and adjusted EPS.

Higher full-year 2025 adjusted results were primarily driven by recovery of growing infrastructure investments to serve customers and growth in our service territories. These items were partially offset by higher O&M, interest expense, property taxes and depreciation on a growing asset base.

The company is introducing 2026 adjusted EPS guidance of $6.55 to $6.80 and extending its long-term adjusted EPS growth rate of 5% to 7% through 2030 off the 2025 guidance range midpoint of $6.30. Management does not forecast reported GAAP EPS and related long-term growth rates.

"The fourth quarter marked a strong finish to a productive year, where we met every financial goal, progressed our economic development pipeline, broke ground on 5 gigawatts of new dispatchable generation resources, and continued to deliver value for customers," said Harry Sideris, Duke Energy president and chief executive officer. "The cost of energy has always been and will remain a key focus for our company. We continue to find new ways to deliver affordable energy for our customers, keeping our rates below the national average and rate changes below inflation."

"We enter 2026 with incredible momentum. The fundamentals of our business have never been stronger, and we operate in some of the most attractive jurisdictions in the nation. With the largest regulated capital plan in the industry, a balance sheet prepared for growth, and contracted demand from AI and advanced manufacturing, we are well-positioned to deliver 5% to 7% EPS growth through 2030."

**Quarterly results**

Duke Energy's fourth-quarter 2025 reported EPS was $1.50, compared to $1.54 for the fourth quarter of 2024. Duke Energy's fourth-quarter 2025 adjusted EPS was $1.50, compared to $1.66 for the fourth quarter of 2024. Lower adjusted results for the quarter compared to last year were primarily driven by higher O&M, interest expense, depreciation on a growing asset base, contributions to the Duke Energy Foundation, along with a higher effective tax rate. These items were partially offset by recovery of infrastructure investments.

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

The discussion below of fourth-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 fourth-quarter 2025 segment income of $1,209 million, compared to segment income of $1,208 million in the fourth quarter of 2024.

On an adjusted basis, Electric Utilities and Infrastructure recognized fourth-quarter 2025 segment income of $1,209 million, compared to segment income of $1,238 million, in the fourth quarter of 2024. This represents a decrease of $0.04 per share, excluding share dilution of $0.01 per share. Lower quarterly results were primarily driven by higher O&M, depreciation on a growing asset base and interest expense, partially offset by recovery of infrastructure investments.

**Gas Utilities and Infrastructure**

On a reported basis, Gas Utilities and Infrastructure recognized fourth-quarter 2025 segment income of $230 million, compared to segment income of $189 million in the fourth quarter of 2024.

On an adjusted basis, Gas Utilities and Infrastructure recognized fourth-quarter 2025 segment income of $230 million, compared to segment income of $231 million, in the fourth quarter of 2024. Flat quarterly results were primarily driven by recovery of infrastructure investments, offset by higher O&M and taxes.

**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 basis, Other recognized a fourth-quarter 2025 segment loss of $272 million, compared to a segment loss of $204 million in the fourth quarter of 2024.

Duke Energy News Release&nbsp;&nbsp;&nbsp;&nbsp; 3

On an adjusted basis, Other recognized a fourth-quarter 2025 segment loss of $272 million, compared to a segment loss of $186 million in the fourth quarter of 2024. This represents a decrease of $0.11 per share. Lower quarterly results were primarily driven by higher contributions to the Duke Energy Foundation, interest expense and the absence of tax optimization in the prior year.

**Effective tax rate**

Duke Energy's consolidated reported effective tax rate for the fourth quarter of 2025 was 11.3% compared to 8.1% in the fourth quarter of 2024. The increase was primarily due to tax benefits recognized in the prior year related to the utilization of previously valued carryforward attributes.

Duke Energy's consolidated adjusted effective tax rate for the fourth quarter of 2025 was 11.3% compared to 9.3% in the fourth quarter of 2024. The increase was primarily due to tax benefits recognized in the prior year related to the utilization of previously valued carryforward attributes.

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

An earnings conference call for analysts is scheduled at 10 a.m. ET today to discuss fourth-quarter and year-end 2025 financial results and other business and financial updates.

**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.

------

Duke Energy News Release&nbsp;&nbsp;&nbsp;&nbsp; 5

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regulatory matters primarily represents net impairment charges related to Duke Energy Carolinas' and Duke Energy Progress' South Carolina 2024 rate case orders and charges related to Duke Energy Indiana post-retirement benefits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• System post-implementation costs represents the net impact of charges related to nonrecurring customer billing adjustments as a result of implementation of a new customer system.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Preferred redemption costs represents charges related to the redemption of Series B Preferred Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Noncore asset sales and net impairments primarily represents charges related to certain joint venture electric transmission projects and certain renewable natural gas investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Captive Storm Deductible represents charges related to an insurance deductible for Hurricane Helene property losses.

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 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&nbsp;&nbsp;&nbsp;&nbsp; 6

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.

**Forward-Looking Information**

This document includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are based on management's beliefs and assumptions and can often be identified by terms and phrases that include "anticipate," "believe," "intend," "estimate," "expect," "continue," "should," "could," "may," "plan," "project," "predict," "will," "potential," "forecast," "target," "guidance," "outlook" or other similar terminology. Various factors may cause actual results to be materially different than the suggested outcomes within forward-looking statements; accordingly, there is no assurance that such results will be realized. These factors include, but are not limited to:

◦ Operational interruptions to our natural gas distribution and transmission activities;

◦ The availability of adequate interstate pipeline transportation capacity and natural gas supply;

◦ The impact on facilities and business from a terrorist or other attack, war, vandalism, cybersecurity threats, data security breaches, operational events, information technology failures or other catastrophic events, such as severe storms, fires, explosions, pandemic health events or other similar occurrences;

◦ The inherent risks associated with the operation of nuclear facilities, including environmental, health, safety, regulatory and financial risks, including the financial stability of third-party service providers;

◦ The timing and extent of changes in commodity prices, including any impact from increased tariffs, export controls and interest rates, and the ability to timely recover such costs through the regulatory process, where appropriate, and their impact on liquidity positions and the value of underlying assets;

◦ The results of financing efforts, including the ability to obtain financing on favorable terms, which can be affected by various factors, including credit ratings, interest rate fluctuations, compliance with debt covenants and conditions, an individual utility's generation portfolio, and general market and economic conditions;

◦ Credit ratings of the Duke Energy Registrants may be different from what is expected;

◦ Declines in the market prices of equity and fixed-income securities and resultant cash funding requirements for defined benefit pension plans, other post-retirement benefit plans and nuclear decommissioning trust funds;

◦ Construction and development risks associated with the completion of the Duke Energy Registrants' capital investment projects, including risks related to financing, timing and receipt of necessary regulatory approvals, obtaining and complying with terms of permits, meeting construction budgets and schedules, obtaining sufficient skilled labor and satisfying operating and environmental performance standards, as well as the ability to recover costs from customers in a timely manner, or at all;

(a)&nbsp;&nbsp;&nbsp;&nbsp;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.
