Duke Energy reports third-quarter 2021 financial results
▪Third-quarter 2021 reported EPS of $1.79 and adjusted EPS of $1.88
▪Results driven by continued strength in Electric Utilities and Infrastructure
▪North Carolina clean energy legislation establishes state's carbon reduction goal of 70% by 2030, introduces modernized ratemaking tools
▪Company narrows 2021 adjusted EPS guidance range to $5.15 to $5.30 and reaffirms long-term adjusted EPS growth rate of 5% to 7% through 2025
CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced third-quarter 2021 reported EPS of $1.79, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.88. This is compared to reported EPS of $1.74 and adjusted EPS of $1.87 for the third quarter of 2020.
Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between the third-quarter 2021 reported and adjusted EPS is due to an impairment charge related to the 2018 South Carolina rate cases, Coal Combustion Residuals Settlement Agreement ("CCR Settlement Agreement") and insurance proceeds, workplace and workforce realignment costs and exit obligations from gas pipeline investments.
Higher third-quarter 2021 adjusted results were led by growth in Electric Utilities and Infrastructure from rate case contributions and higher volumes. These items were partially offset by higher O&M expenses and share dilution.
“We delivered strong results in the third quarter and continue to execute on our clean energy strategy in a way that provides sustainable value to our customers, communities and shareholders,” said Lynn Good, Duke Energy chair, president and chief executive officer. “Our net-zero emission goals are driving our investment strategy, long-term planning and operational execution and we are making significant progress on all fronts. Over the next decade, we have one of the largest growth capital investment plans in the country to build the infrastructure needed to support a clean energy future."
“We are well-positioned to deliver results within our narrowed guidance range of $5.15 to $5.30, and reaffirm our long-term EPS growth rate of 5% to 7% through 2025, based off our original 2021 guidance range.”

Business segment results
In addition to the following summary of third-quarter 2021 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 2021 segment income of $1,425 million, compared to segment income of $1,381 million in the third quarter of 2020. In addition to the drivers below, third-quarter 2021 and 2020 results include impacts from an impairment charge related to the 2018 South Carolina rate cases, coal ash settlement in North Carolina, including insurance proceeds distributed in accordance with the CCR Settlement Agreement, and partial settlements from Duke Energy Carolinas and Duke Energy Progress North Carolina rates cases. These charges were treated as special items and excluded from adjusted earnings.
On an adjusted basis, Electric Utilities and Infrastructure recognized third-quarter 2021 segment income of $1,489 million, compared to segment income of $1,412 million in the third quarter of 2020, an increase of $0.10 per share, excluding share dilution of $0.08 per share. Higher quarterly results were primarily due to volumes (+$0.11 per share) and contributions from rate cases (+$0.09 per share). These results were partially offset by higher O&M expenses (-$0.08 per share).
Gas Utilities and Infrastructure
On a reported basis, Gas Utilities and Infrastructure recognized a third-quarter 2021 segment loss of $3 million, compared to a loss of $73 million in the third quarter of 2020. In addition to the drivers outlined below, third-quarter 2021 and 2020 results include costs related to the cancellation of the ACP investment. These charges were treated as special items and excluded from adjusted earnings.
On an adjusted basis, Gas Utilities and Infrastructure recognized a third-quarter 2021 segment loss of $5 million, compared to a loss of $8 million in the third quarter of 2020, flat per share. Margin expansion (+$0.01 per share) was offset by higher depreciation on a growing asset base (-$0.01 per share).
Commercial Renewables
On a reported and adjusted basis, Commercial Renewables recognized third-quarter 2021 segment income of $78 million, compared to reported and adjusted segment income of $60 million in the third quarter of 2020. This represents an increase of $0.02 per share, excluding share dilution of $0.01 per share. Higher quarterly results were primarily driven by new renewable projects (+$0.03 per share).

Duke Energy News Release 3
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 third-quarter 2021 net loss of $134 million compared to a net loss of $103 million in the third quarter of 2020. In addition to the drivers outlined below, third-quarter 2021 results include workplace and workforce realignment costs. This amount was treated as a special item and excluded from adjusted earnings.
On an adjusted basis, Other recognized a third-quarter 2021 net loss of $127 million. This is compared to an adjusted net loss of $103 million in the third quarter of 2020, a decrease of $0.03 per share, excluding share dilution of -$0.01 per share. Lower quarterly results at Other were primarily due to higher income tax expense.
Effective tax rate
Duke Energy's consolidated reported effective tax rate for the third-quarter of 2021 was 6.6% compared to 7.8% in the third quarter of 2020. The decrease in the effective tax rate was primarily due to an increase in the amortization of excess deferred taxes.
The effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items for the third quarter of 2021 was 7.1% compared to 9.0% in the third quarter of 2020. The decrease was primarily due to an increase 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.

Special Items and Non-GAAP Reconciliation
The following tables present a reconciliation of GAAP reported earnings per share to adjusted earnings per share for third-quarter 2021 and 2020 financial results:

(In millions, except per share amounts) | After-Tax Amount | 3Q 2021 EPS | 3Q 2020 EPS
EPS, as reported |  | $ | 1.79 |  | $ | 1.74 |

Gas Pipeline Investments | $ | (2) |  | — |  |

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:
•Gas Pipeline Investments represents costs related to the cancellation of the ACP investment and additional exit obligations.

Duke Energy News Release 5
•Workplace and Workforce Realignment represents costs attributable to business transformation, including long-term real estate strategy changes and workforce realignment.
•Regulatory Settlements represents an impairment charge related to the 2018 South Carolina rate cases, charges related to the CCR Settlement Agreement and insurance proceeds distributed in accordance with that agreement and Duke Energy Carolinas and Duke Energy Progress partial settlements in the 2019 North Carolina rate cases.
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 (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 as a measure of historical and anticipated future segment performance. Adjusted segment income 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 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.
