**Duke Energy reports first-quarter 2026 financial results**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ First-quarter 2026 reported EPS of $1.97 and adjusted EPS of $1.93**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ Seizing growth opportunities with a total of 7.6 GW of economic development projects secured under Electric Service Agreements**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**▪ Successfully closed $5.3 billion strategic transactions to strengthen balance sheet and support growth**

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced first-quarter 2026 reported EPS of $1.97, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.93. This is compared to reported and adjusted EPS of $1.76 for the first quarter of 2025.

Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between first-quarter 2026 reported and adjusted EPS includes gains on asset sales, charges related to legal and regulatory settlements, and results of discontinued operations.

Higher first-quarter 2026 adjusted results were driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions, along with favorable weather. These items were partially offset by higher O&M expenses, including storm costs, as well as higher depreciation on a growing asset base.

The 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're advancing the economies of the states we serve by making the right investments at the right time in a way that delivers value for our customers and communities," said Harry Sideris, Duke Energy president and chief executive officer. "From maximizing our existing fleet, to constructing new generation and strengthening the grid, we're executing today and building for the future – all while pursuing solutions to keep rates as low as possible."

**Business segment results**

In addition to the following summary of first-quarter 2026 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. 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 first-quarter 2026 segment income of $1,254 million, compared to segment income of $1,276 million in the first quarter of 2025. In addition to the drivers outlined below, first-quarter 2026 results include the impact of charges related to legal and regulatory settlements at Duke Energy Carolinas and Duke Energy Progress, which were treated as special items and excluded from adjusted earnings.

On an adjusted basis, Electric Utilities and Infrastructure recognized first-quarter 2026 segment income of $1,404 million, compared to segment income of $1,276 million in the first quarter of 2025. This represents an increase of $0.16 per share. Higher quarterly results were primarily driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions, along with favorable weather, partially offset by higher O&M expenses, including storm costs, along with higher depreciation on a growing asset base.

**Gas Utilities and Infrastructure**

On a reported basis, Gas Utilities and Infrastructure recognized first-quarter 2026 segment income of $532 million, compared to segment income of $349 million in the first quarter of 2025. In addition to the drivers outlined below, first-quarter 2026 results include the impact of gains on asset sales related to Piedmont's Tennessee business and SustainRNG projects, which were treated as special items and excluded from adjusted earnings.

On an adjusted basis, Gas Utilities and Infrastructure recognized first-quarter 2026 segment income of $361 million, compared to segment income of $349 million in the first quarter of 2025. This represents an increase of $0.01 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 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 first-quarter 2026 segment loss of $263 million, compared to segment loss of $260 million in the first quarter of 2025.

**Effective tax rate**

Duke Energy's consolidated reported effective tax rate for the first quarter of 2026 was 17.6% compared to 12.1% in the first quarter of 2025. The increase in the reported effective tax rate was primarily due to non-deductible goodwill associated with the sale of Piedmont's Tennessee business.

Duke Energy's consolidated adjusted effective tax rate was 10.6% for the first quarter of 2026 compared to 12.2% in the first quarter of 2025. The decrease in the adjusted effective tax rate was primarily due to an increase in the amortization of nuclear production tax credits.

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 first-quarter 2026 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.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Legal and Regulatory Settlements represent the impact of charges related to legal settlements as well as regulatory matters related to the establishment of a regulatory liability associated with an energy efficiency program at Duke Energy Carolinas and Duke Energy Progress.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Asset Sales represent the impact of gains on sale of assets related to Piedmont's Tennessee business and certain renewable natural gas investments.

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.

------

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

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.

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)&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. On March 31, 2026, Piedmont closed on the sale of its Tennessee business.
