Duke Energy reports second-quarter 2026 financial results

▪Second-quarter 2026 reported EPS of $1.38 and adjusted EPS of $1.43; strong first half positions company to deliver full-year results within guidance range

▪T1Constructive regulatory outcomes support critical investments to maintain reliability and deliver customer value

▪T2Generation build supports growth in jurisdictions, fuels vibrant economies

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced second-quarter 2026 reported EPS of $1.38, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.43. This is compared to reported and adjusted EPS of $1.25 for the second quarter of 2025.

Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between second-quarter 2026 reported and adjusted EPS includes charges related to regulatory settlements.

T3Higher second-quarter 2026 adjusted results were driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions. T4T5These items were partially offset by higher depreciation on a growing asset base and interest expense.

G1T6The company is reaffirming its 2026 adjusted EPS guidance of $6.55 to $6.80 and long-term adjusted EPS growth rate of 5% to 7% through 2030 off the 2025 midpoint of $6.30, with confidence to earn in the top half of the range beginning in 2028. Management does not forecast reported GAAP EPS and related long-term growth rates.

“We had a strong first half of the year, achieving constructive regulatory outcomes, advancing strategic priorities and maintaining excellence in our operational and financial performance,” said Harry Sideris, Duke Energy president and chief executive officer. “Looking ahead, we are well-positioned to deliver on our commitments in 2026 and seize the growth opportunities in some of the most economically attractive states in the country. As we build the critical infrastructure our customers and communities need, we’re ensuring our investments support economic growth and create long-term value while providing reliable energy at the lowest possible cost.”

Duke Energy News Release 2

Business segment results

In addition to the following summary of second-quarter 2026 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 2026 segment income of $1,271 million, compared to segment income of $1,194 million in the second quarter of 2025. In addition to the drivers outlined below, second-quarter 2026 results include the impact of charges related to regulatory settlements, which were treated as special items and excluded from adjusted earnings.

On an adjusted basis, Electric Utilities and Infrastructure recognized second-quarter 2026 segment income of $1,310 million, compared to segment income of $1,194 million in the second quarter of 2025. This represents an increase of $0.15 per share. Higher quarterly results were primarily driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions, partially offset by higher depreciation on a growing asset base and interest expense.

Gas Utilities and Infrastructure

On a reported and adjusted basis, Gas Utilities and Infrastructure recognized second-quarter 2026 segment income of $10 million, compared to segment income of $6 million in the second quarter of 2025. Flat quarterly results were primarily driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions, offset by lower earnings from the sale of Piedmont's Tennessee business.

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 2026 segment loss of $204 million, compared to segment loss of $228 million in the second quarter of 2025. This represents an increase of $0.03 per share. Higher quarterly results were primarily driven by higher returns on investments and lower interest expense.

Duke Energy News Release 3

Effective tax rate

Duke Energy's consolidated reported effective tax rate for the second quarter of 2026 was 12.3% compared to 10.6% in the second quarter of 2025. T7The increase in the reported effective tax rate was primarily due to a decrease in the amortization of excess deferred taxes.

Duke Energy's consolidated adjusted effective tax rate was 12.6% for the second quarter of 2026 compared to 10.6% in the second quarter of 2025. The increase in the adjusted effective tax rate was primarily due to a decrease in the amortization of excess deferred taxes.

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

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 Settlements represent the impact of charges related to the Duke Energy Carolinas' North Carolina rate case settlements.

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.

◦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;

◦The actions of activist shareholders could disrupt our operations, impact our ability to execute on our business strategy, or cause fluctuations in the trading price of our common stock.

Additional risks and uncertainties are identified and discussed in the Duke Energy Registrants' reports filed with the SEC and available at the SEC's website at sec.gov. In light of these risks, uncertainties and assumptions, the events described in the forward-looking statements might not occur or might occur to a different extent or at a different time than described.
