Rhea-AI Filing Summary

Duke Energy reported third-quarter 2026 GAAP and adjusted earnings per share of $1.99, compared with $1.81 a year earlier. Operating revenue was $9.104 billion, versus $8.542 billion, and net income available to common stockholders was $1.551 billion, versus $1.407 billion. Management attributed higher adjusted results mainly to recovery of infrastructure investments and favorable weather, partly offset by higher depreciation, minority-interest impacts, higher interest expense and a higher effective tax rate.

The company narrowed 2026 adjusted EPS guidance to $6.70 to $6.80 and reaffirmed its 5% to 7% long-term adjusted EPS growth rate through 2030, from the 2025 guidance range midpoint of $6.30. Management said it has confidence to earn in the top half of the range beginning in 2028. Duke Energy also said it is executing a generation build to add 16 gigawatts of capacity by 2031.

For the nine months ended September 30, 2026, net cash provided by operating activities was $7.889 billion, compared with $8.672 billion in the prior-year period. Electric Utilities and Infrastructure reported segment income of $1.817 billion, while Gas Utilities and Infrastructure reported a $19 million segment loss.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Adjusted EPS financial

"adjusted earnings, adjusted EPS and adjusted effective tax rate"

Adjusted earnings per share (adjusted eps) is a measure of a company's profit per share that has been modified to exclude certain one-time or unusual items, such as costs from restructuring or asset sales. It provides a clearer picture of the company’s core performance by removing events that may distort the usual earnings. Investors use adjusted eps to better understand a company's ongoing profitability and compare it more accurately over time.

Adjusted effective tax rate financial

"The adjusted effective tax rate is calculated using pretax earnings and income tax expense"

The adjusted effective tax rate is the percentage of a company’s pre-tax income that it would normally pay in taxes after removing one-time or unusual items, giving a clearer view of its ongoing tax burden. Like clearing away exceptional expenses to see your regular monthly bill, this adjusted rate helps investors compare companies, forecast future profits and cash flow, and value a business without one-off swings distorting the picture.

Special items financial

"Special items represent certain charges and credits"

Special items are unusual or infrequent gains or losses that a company reports separately from its regular operating profit, such as restructuring costs, asset write-downs, legal settlements, or one-time gains from selling a business. Investors pay attention because these items can make reported profits look better or worse than the company’s ongoing performance—like a homeowner’s one-off roof repair affecting a single month’s budget but not the household’s regular income and expenses.

Duke Energy reports third-quarter 2026 financial results

▪Third-quarter 2026 reported and adjusted EPS of $1.99

▪Company narrows 2026 adjusted EPS guidance range to $6.70 to $6.80; strong year-to-date performance positions company to deliver results near the top end

▪Executing record generation build to add 16 gigawatts of capacity by 2031, supporting customer value, economic growth and reliable service

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced third-quarter 2026 reported EPS, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.99. This is compared to reported and adjusted EPS of $1.81 for the third quarter of 2025. Adjusted EPS excludes the impact of certain items that are included in reported EPS.

Higher third-quarter 2026 adjusted results were driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions and favorable weather. These items were partially offset by higher depreciation on a growing asset base, impacts from minority interest investments, higher interest expense, and a higher effective tax rate.

The company is narrowing its 2026 adjusted EPS guidance range to $6.70 to $6.80 and reaffirming its long-term adjusted EPS growth rate of 5% to 7% through 2030 off the 2025 guidance range 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 delivered strong results through the first three quarters of the year, reflecting disciplined execution as we continue investing in the reliable service our customers depend on while keeping costs as low as possible,” said Harry Sideris, Duke Energy president and chief executive officer. “The growth across our states creates a significant opportunity, and our focus is on making sure that growth benefits everyone – protecting existing customers, strengthening reliability and supporting the communities we serve. We are well positioned to deliver on our 2026 priorities and create lasting value for our customers, communities and shareholders.”

Business segment results

In addition to the following summary of third-quarter 2026 business segment performance, comprehensive tables with detailed EPS drivers for the third quarter compared to prior year are provided at the end of this news release.

The discussion below of third-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 and adjusted basis, Electric Utilities and Infrastructure recognized third-quarter 2026 segment income of $1,817 million, compared to segment income of $1,658 million in the third quarter of 2025. This represents an increase of $0.20 per share. Higher quarterly results were primarily driven by recovery of infrastructure investments to reliably serve customers in our growing jurisdictions and favorable weather, partially offset by higher depreciation on a growing asset base, impacts from minority interest investments, and higher interest expense.

Gas Utilities and Infrastructure

On a reported and adjusted basis, Gas Utilities and Infrastructure recognized third-quarter 2026 segment loss of $19 million, compared to segment loss of $26 million in the third quarter of 2025. This represents an increase of $0.01 per share. Higher quarterly results were primarily driven by lower O&M expense.

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 third-quarter 2026 segment loss of $247 million, compared to segment loss of $225 million in the third quarter of 2025. This represents a decrease of $0.03 per share. Lower quarterly results were primarily driven by higher captive claims and lower returns on investments.

Effective tax rate

Duke Energy's consolidated reported effective tax rate for the third quarter of 2026 was 15.3% compared to 10.8% in the third quarter of 2025. The increase in the reported effective tax rate was primarily due to a decrease in the amortization of excess deferred income taxes.

Duke Energy's consolidated adjusted effective tax rate was 15.5% for the third quarter of 2026 compared to 10.8% in the third quarter of 2025. The increase in the adjusted effective tax rate was primarily due to a decrease in the amortization of excess deferred income 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.

Earnings conference call for analysts

An earnings conference call for analysts is scheduled at 10 a.m. ET today to discuss third-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.

The call can be accessed via the investors' section (duke-energy.com/investors) of Duke Energy’s website or by dialing 833.461.5787 in the U.S. or 585.542.9983 outside the U.S. The confirmation code is 463805206. Please call in 10 to 15 minutes prior to the scheduled start time.

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. There were no special items included in the periods presented.

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 4

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) 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.
