Duke Energy reports fourth-quarter and full-year 2023 financial results
▪2023 reported EPS of $3.54 and adjusted EPS of $5.56, closing the year within guidance range
▪Constructive rate case outcomes and portfolio simplification in 2023 provide clarity and momentum
▪Five-year capital plan increasing to $73 billion to support unprecedented growth in the communities we serve
CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced 2023 full-year reported EPS of $3.54, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $5.56. This is compared to reported and adjusted EPS of $3.17 and $5.27, respectively, for the full-year 2022.
Adjusted EPS excludes the impact of certain items that are included in reported EPS. In 2023, these included charges related to organizational optimization and regulatory matters along with results from discontinued operations.
Higher full-year 2023 adjusted results were primarily driven by contributions from rate cases, growth from riders and other retail margin and lower O&M expense along with a lower effective tax rate. These items were partially offset by higher interest expense and depreciation on a growing asset base along with unfavorable weather and electric volumes.
The company is introducing 2024 adjusted EPS guidance of $5.85 to $6.10, and reaffirming its long-term adjusted EPS growth rate of 5% to 7% through 2028 off the 2024 midpoint of $5.98. Management does not forecast reported GAAP EPS and related long-term growth rates.
“Today we announced strong fourth-quarter results, concluding a year of resilience and agility as we overcame external challenges. We advanced strategic initiatives and delivered constructive regulatory outcomes that benefit our customers and company, while maintaining our commitment to safety, reliability and affordability,” said Lynn Good, Duke Energy chair, president and chief executive officer.
“We enter 2024 with a clear vision, significant momentum and an increased $73 billion, five-year capital plan that will support our energy transition and the unprecedented growth of our jurisdictions. The strength of our regulated utilities and our increasing capital profile give us confidence in our ability to deliver sustainable value and earnings growth of 5% to 7% through 2028.”

Quarterly results
Duke Energy's fourth-quarter 2023 reported EPS was $1.27, compared to reported loss per share of $0.86 for the fourth quarter of 2022. Duke Energy's fourth-quarter 2023 adjusted EPS was $1.51, compared to $1.11 for the fourth quarter of 2022. Higher adjusted results for the quarter compared to last year were driven by lower O&M expense, favorable rate case impacts along with growth from riders and other retail margin, and lower tax expense and franchise tax benefits, partially offset by higher interest expense and depreciation on a growing asset base.
In addition to the following summary of fourth-quarter 2023 business segment performance, comprehensive tables with detailed EPS drivers for the fourth-quarter and full-year 2023 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 2023 segment income of $1,135 million, compared to reported segment income of $692 million in the fourth quarter of 2022. In addition to the drivers outlined below, fourth-quarter 2023 results include impacts related to the Duke Energy Carolinas rate case order, which was treated as a special item and excluded from adjusted earnings.
On an adjusted basis, Electric Utilities and Infrastructure recognized fourth-quarter 2023 segment income of $1,115 million, compared to adjusted segment income of $811 million, in the fourth quarter of 2022. On an adjusted basis, this represents an increase of $0.40 per share. Higher quarterly results were primarily driven by lower O&M expense, favorable rate case impacts along with growth from riders and other retail margin, and lower tax expense. These items were partially offset by higher interest expense and depreciation on a growing asset base.
Gas Utilities and Infrastructure
On a reported and adjusted basis, Gas Utilities and Infrastructure recognized fourth-quarter 2023 segment income of $192 million, compared to reported and adjusted segment income of $191 million in the fourth quarter of 2022. Flat quarterly results were primarily driven by favorable riders and other retail margin offset by higher interest 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 basis, Other recognized a fourth-quarter 2023 net loss of $228 million, compared to a net loss of $257 million in the fourth quarter of 2022.

Duke Energy News Release 3
On an adjusted basis, Other recognized a net loss of $133 million, in the fourth quarter of both 2023 and 2022. Flat quarterly results were primarily driven by higher interest expense offset by franchise tax benefits.
Discontinued Operations
Discontinued operations primarily includes the impairments recorded related to the sale of the Commercial Renewables business along with the operating results from Duke Energy's Commercial Renewables business. In November 2022, the company announced it had initiated a sale process of the Commercial Renewables business. The sales of the utility-scale solar and wind assets as well as the distributed generation assets closed in October 2023, completing the company's transition to a fully regulated utility.
For the fourth quarter of 2023, Duke Energy's GAAP reported Loss From Discontinued Operations, net of tax, includes an impairment loss on the sale of the Commercial Renewables business and other transaction costs.
Effective tax rate
Duke Energy's consolidated reported effective tax rate for the fourth quarter of 2023 was 9.7% compared to 0.5% in the fourth quarter of 2022. The increase was primarily due to a decrease in the amortization of excess deferred taxes and regulatory settlement charges in the prior year.
The effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items for the fourth quarter of 2023 was 10.5% compared to the effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items of 8.4% in the fourth quarter of 2022. The increase 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 effective tax rate including noncontrolling interests and preferred dividends and excluding special items.

Duke Energy News Release 5
Non-GAAP financial measures
Management evaluates financial performance in part based on non-GAAP financial measures, including adjusted earnings, adjusted EPS and effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items. Adjusted earnings and adjusted EPS represent income (loss) from continuing operations available to Duke Energy Corporation common stockholders in dollar and per share amounts, adjusted for the dollar and per share impact of special items. The effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items is calculated using pretax earnings and income tax expense, both as adjusted for the impact of noncontrolling interests, preferred dividends and special items. As discussed below, 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 effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items 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.
Special items included in the periods presented include the following items, which management believes do not reflect ongoing costs:
•Regulatory matters primarily represents net impairment charges related to Duke Energy Carolinas' and Duke Energy Progress' North Carolina rate case orders.
•Organizational optimization represents costs associated with strategic repositioning to a fully regulated utility.
•Workplace and workforce realignment represents costs attributable to business transformation, including long-term real estate strategy changes and workforce reduction.
•Regulatory matters and litigation represents the net impact of charges related to the Indiana court rulings on coal ash and other unrelated ongoing litigation.
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).

Duke Energy News Release 6
Management evaluates segment performance based on segment income (loss) and other net loss. Segment income (loss) is defined as income (loss) from continuing operations net of income attributable to noncontrolling interests and preferred stock dividends. Segment income (loss) includes intercompany revenues and expenses that are eliminated in the Condensed Consolidated Financial Statements. Management also uses adjusted segment income (loss) as a measure of historical and anticipated future segment performance. Adjusted segment income (loss) is a non-GAAP financial measure, as it is based upon segment income (loss) adjusted for special items, which are discussed above. Management believes the presentation of adjusted segment income (loss) provides useful information to investors, as it provides them with an additional relevant comparison of a segment’s performance across periods. The most directly comparable GAAP measure for adjusted segment income or adjusted other net loss is segment income (loss) 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 the company is unable to forecast all special items, as discussed above.
Duke Energy’s adjusted earnings, adjusted EPS and adjusted segment income may not be comparable to similarly titled measures of another company because other companies may not calculate the measures in the same manner.
