Duke Energy reports third-quarter 2023 financial results
▪Third-quarter 2023 reported EPS of $1.59 and adjusted EPS of $1.94
▪Constructive North Carolina rate case outcome represents first implementation of performance-based regulations under HB 951
▪Company completes transition to fully regulated company
CHARLOTTE, N.C. - Duke Energy (NYSE: DUK) today announced third-quarter 2023 reported EPS of $1.59, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.94. This is compared to reported EPS of $1.81 and adjusted EPS of $1.78 for the third quarter of 2022.
Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between the third-quarter 2023 reported and adjusted EPS includes the results of discontinued operations, as well as the net impact of special items for charges primarily related to the Duke Energy Carolinas North Carolina rate case settlement and the Duke Energy Progress North Carolina rate case order.
Higher third-quarter 2023 adjusted results were driven by a lower effective tax rate, growth from riders and other retail margin, and favorable rate case impacts. These items were partially offset by higher interest expense and lower volumes.
The company is narrowing the adjusted 2023 EPS guidance range to $5.55 to $5.65 and reaffirming the long-term adjusted EPS growth rate of 5% to 7% through 2027 off the original 2023 midpoint of $5.65. Management does not forecast reported GAAP EPS and related long-term growth rates.
"Over the past year, we've built considerable momentum on our strategic priorities, delivering a series of constructive regulatory outcomes, and solidifying our path as a fully regulated utility. We've also responded to revenue pressures from mild weather and lower customer usage with agile cost reduction efforts," said Lynn Good, Duke Energy chair, president and chief executive officer.
"As we execute our $65 billion five-year capital plan - one of the largest in our industry - our long-term organic growth strategy has never been more clear. Our attractive dividend yield, coupled with long-term earnings growth from investments in our regulated utilities, has us well-positioned to deliver sustainable value and earnings growth of 5 to 7% over the next five years."

Business segment results
In addition to the following summary of third-quarter 2023 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, Electric Utilities and Infrastructure recognized third-quarter 2023 segment income of $1,447 million, compared to reported segment income of $1,540 million in the third quarter of 2022. In addition to the drivers outlined below, third-quarter 2023 results include impacts related to the Duke Energy Carolinas North Carolina rate case settlement and the Duke Energy Progress North Carolina rate case order, which was treated as a special item and excluded from adjusted earnings.
On an adjusted basis, Electric Utilities and Infrastructure recognized third-quarter 2023 segment income of $1,531 million, compared to adjusted segment income of $1,540 million in the third quarter of 2022. On an adjusted basis, this represents a decrease of $0.01 per share. Lower quarterly results were primarily due to higher interest expense and lower volumes, partially offset by growth from riders and other retail margin and favorable rate case impacts.
Gas Utilities and Infrastructure
On a reported and adjusted basis, Gas Utilities and Infrastructure recognized third-quarter 2023 segment income of $15 million, compared to reported and adjusted segment income of $4 million in the third quarter of 2022. On an adjusted basis, this represents an increase of $0.01 per share. Higher quarterly results were primarily driven by growth from riders and other retail margin and lower O&M expense, partially offset by higher interest expense and depreciation.
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 2023 segment loss of $59 million, compared to reported and adjusted segment loss of $183 million in the third quarter of 2022. On an adjusted basis, this represents an increase of $0.16 per share. Higher quarterly results were primarily due to a lower effective tax rate.


Duke Energy News Release 3

Discontinued Operations
Discontinued operations primarily includes the impairments recorded for 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 third 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 third quarter of 2023 was 2.8% compared to 10.1% in the third quarter of 2022. The decrease in the effective tax rate was primarily due to favorable adjustments related to certain allowable deductions as a result of ongoing tax efficiency efforts, partially offset by a decrease in the amortization of excess deferred taxes.

The effective tax rate including noncontrolling interests and preferred dividends and excluding special items for the third quarter of 2023 was 3.9% compared to 10.2% in the third quarter of 2022. The decrease was primarily due to favorable adjustments related to ongoing tax efficiency efforts for certain allowable deductions in periods currently open under federal statute, partially offset by a decrease in the amortization of excess deferred taxes. The full year effective tax rate is trending toward the low end of the original guidance range of 11% to 13%.
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.

Special Items and Non-GAAP Reconciliation
The following table presents a reconciliation of GAAP reported earnings per share to adjusted earnings per share for third-quarter 2023 and 2022 financial results:
(In millions, except per share amounts) After-Tax Amount
3Q 2023 EPS
3Q 2022 EPS
Earnings Per Share, as reported
$ 1.59 $ 1.81
Adjustments to reported EPS:

Regulatory Matters $ 84 0.11
Discontinued operations $ 190 $ 0.24
Third Quarter 2022
Discontinued operations (22) (0.03)
Total adjustments $ 0.35 $ (0.03)
EPS, adjusted $ 1.94 $ 1.78

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 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 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 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 impairment charges related to Duke Energy Carolinas' North Carolina rate case settlement and Duke Energy Progress' North Carolina rate case order.


Duke Energy News Release 5

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).
Management evaluates segment performance based on segment income and other net loss. Segment income and other net loss is defined as income (loss) from continuing operations net of income attributable to noncontrolling interests and preferred stock dividends. Segment income and other net loss includes 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 a measure of historical and anticipated future segment performance. Adjusted segment income and adjusted other net loss is a non-GAAP financial measure, as it is based upon segment income and other net loss adjusted for special items, which are discussed above. Management believes the presentation of adjusted segment income and adjusted other net 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 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 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.
