Duke Energy reports fourth-quarter and full-year 2022 financial results
▪2022 reported EPS of $3.33 and adjusted EPS of $5.27, closing the year above the midpoint of updated guidance range
▪Constructive Carbon Plan outcome advances clean energy transition in the Carolinas
▪Five-year capital plan increases to $65 billion with over 80% funding investments in the grid and clean energy transition
CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced 2022 full-year reported EPS of $3.33, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $5.27. This is compared to reported and adjusted EPS of $4.94 and $4.99, respectively, for the full-year 2021.
Adjusted EPS excludes the impact of certain items that are included in reported EPS. In 2022, these included an estimated impairment on the sale of the Commercial Renewables business, charges related to regulatory matters and litigation, and workplace and workforce realignment costs.
Higher full-year 2022 adjusted results were primarily driven by higher electric volumes and favorable weather, in addition to rate case contributions. These items were partially offset by higher financing costs, higher depreciation and property taxes on a growing asset base, storm costs, and unfavorable market impacts on benefits trusts and captive insurance.
The company is reaffirming the adjusted 2023 EPS guidance range of $5.55 to $5.75, and long-term adjusted EPS growth rate of 5% to 7% through 2027 off the 2023 midpoint of $5.65. Management does not forecast reported GAAP EPS and related long-term growth rates.
“We delivered a strong fourth quarter, closing out a successful year during which we met our financial goals, made progress on our growth strategy, and advanced our clean energy transformation to benefit customers,” said Lynn Good, Duke Energy chair, president and chief executive officer. “Our path forward is clear and underpinned by the strength of our regulated businesses, a disciplined approach to cost management and a robust $65 billion capital plan. We’re well positioned to earn solidly within our 5% to 7% growth rate through 2027.”
“As we continue to navigate our energy transition, we’ll do so responsibly – protecting affordability and reliability for our customers and delivering consistent value to our communities and shareholders.”

Quarterly results
Duke Energy's fourth-quarter 2022 reported loss per share was $(0.71), compared to earnings per share of $0.93 for the fourth quarter of 2021. Duke Energy's fourth-quarter 2022 adjusted EPS was $1.11, compared to $0.88 for the fourth quarter of 2021. Higher adjusted results for the quarter compared to last year were driven by higher volumes, lower O&M expense, favorable weather, favorable riders and other retail margin, partially offset by higher interest expense.
In addition to the following summary of fourth-quarter 2022 business segment performance, comprehensive tables with detailed EPS drivers for the fourth-quarter and full-year 2022 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 and adjusted basis, Electric Utilities and Infrastructure re cognized fourth-quarter 2022 segment income of $811 million, compared to reported and adjusted segment income of $670 million and $675 million, respectively, in the fourth quarter of 2021. On an adjusted basis, this represents an increase of $0.17 per share. Higher quarterly results were primarily driven by higher volumes, favorable weather, and lower O&M expense. These items were partially offset by higher financing costs and higher depreciation and property tax expense on a growing asset base.
Gas Utilities and Infrastructure
On a reported and adjusted basis, Gas Utilities and Infrastructure recognized fourth-quarter 2022 segment income of $191 million, compared to reported and adjusted segment income of $137 million in the fourth quarter of 2021. On an adjusted basis, this represents an increase of $0.07 per share. Higher quarterly results were primarily driven by sales growth and rate case contributions.
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 2022 net loss of $257 million, compared to a net loss of $128 million in the fourth quarter of 2021. In addition to the drivers outlined below, fourth-quarter 2022 results include charges related to litigation as well as workplace and workforce realignment costs.
On an adjusted basis, Other recognized a fourth-quarter 2022 net loss of $133 million, compared to a net loss of $122 million in the fourth quarter of 2021, a decrease of $0.01 per share. Lower quarterly results were primarily driven by higher financing costs, partially offset by lower contributions to the Duke Energy Foundation.

Duke Energy News Release 3
Discontinued Operations
Discontinued operations primarily includes the estimated impairment on the sale of the Commercial Renewables business along with 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, which is expected to close later in 2023.
For the fourth quarter of 2022, Duke Energy's GAAP reported Loss From Discontinued Operations, net of tax, includes an estimated impairment loss on the sale of the Commercial Renewables business and other transaction costs of approximately $1.3 billion.
Effective tax rate
Duke Energy's consolidated reported effective tax rate for the fourth quarter of 2022 was 5.5% compared to 0.1% in the fourth quarter of 2021. The increase was primarily due to realization of capital loss carry forward benefit in the prior year partially offset by an increase in charges due to workplace and workforce realignment.
The effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items for the fourth quarter of 2022 was 8.4% compared to the effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items of 0.3% in the fourth quarter of 2021. The increase was primarily due to realization of capital loss carry forward benefit in the prior year.
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:
•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 2022 Indiana Supreme Court ruling on coal ash and other unrelated ongoing litigation.
•Regulatory settlements represents an impairment charge related to the South Carolina Supreme Court decision on coal ash, insurance proceeds and Duke Energy Carolinas and Duke Energy Progress coal ash settlement.
•Gas pipeline investments represents additional exit obligations related to ACP.
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.
