Duke Energy reports second-quarter 2021 financial results
▪Second-quarter 2021 reported EPS of $0.96 and adjusted EPS of $1.15
▪Growth driven by continued strength in Electric Utilities and Infrastructure
▪Surpassed 10,000 megawatts of renewable energy on path to net-zero carbon emissions by 2050
▪Company reaffirms 2021 adjusted EPS guidance range of $5.00 to $5.30 and long-term adjusted EPS growth rate of 5% to 7% through 2025
CHARLOTTE, N.C. - Duke Energy (NYSE: DUK) today announced second-quarter 2021 reported EPS of $0.96, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.15. This is compared to a reported loss per share of $(1.13) and adjusted EPS of $1.08 for the second quarter of 2020.
Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between the second-quarter 2021 reported and adjusted EPS is due to workplace and workforce realignment costs and exit obligations from gas pipeline investments.
Higher second-quarter 2021 adjusted results were led by growth in Electric Utilities and Infrastructure from rate case contributions, higher volumes and higher wholesale earnings. These items were partially offset by higher O&M expenses, lower Commercial Renewables earnings, the loss of ACP earnings and share dilution.
'Our strong second-quarter results demonstrate the continued execution of our clean energy strategy,' said Lynn Good, Duke Energy chair, president and chief executive officer. 'We recently passed 10,000 MW of renewable energy on our path to net-zero carbon emissions by 2050. We're investing in our transmission and distribution assets to strengthen grid resiliency, accommodate more renewables and support state economic development efforts. And, we're collaborating with stakeholders and policymakers to advance supportive energy policy. We expect 2021 adjusted earnings per share to be in the range of $5.00 to $5.30 and expect to grow earnings 5% to 7% through 2025, based off the $5.15 midpoint.
'Moving forward, we're leading the most ambitious clean energy transition in North America while providing safe, reliable and affordable energy solutions to our customers and communities across the Southeast and Midwest, enabled by our scope and scale.'

Business segment results
In addition to the following summary of second-quarter 2021 business segment performance, comprehensive tables with detailed EPS drivers for the second quarter compared to prior year are provided at the end of this news release.
The discussion below of second-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 recognized second-quarter 2021 segment income of $935 million, compared to segment income of $753 million in the second quarter of 2020, an increase of $0.24 per share, excluding share dilution of $0.04 per share. Higher quarterly results were primarily due to contributions from rate cases (+$0.13 per share), higher volumes (+$0.08 per share), higher wholesale earnings (+$0.05 per share) and other margin (+$0.04 per share). These results were partially offset by higher O&M expenses (-$0.07 per share).
Gas Utilities and Infrastructure
On a reported basis, Gas Utilities and Infrastructure recognized second-quarter 2021 segment income of $17 million, compared to a loss of $1,576 million in the second quarter of 2020. In addition to the drivers outlined below, second-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 second-quarter 2021 segment income of $29 million, compared to $50 million in the second quarter of 2020, a decrease of $0.03 per share. Riders and margin expansion (+$0.01 per share) and contributions from the Tennessee rate case (+$0.01 per share) were offset by the loss of ACP earnings (-$0.03 per share) and higher depreciation on a growing asset base and other taxes (-$0.02 per share).
Commercial Renewables
On a reported and adjusted basis, Commercial Renewables recognized second-quarter 2021 segment income of $47 million, compared to reported and adjusted segment income of $90 million in the second quarter of 2020. This represents a decrease of $0.06 per share, excluding share dilution of $0.01 per share. Lower quarterly results were primarily due to certain renewable projects placed in service in the prior year (-$0.05 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 second-quarter 2021 net loss of $248 million compared to a net loss of $84 million in the second quarter of 2020. In addition to the drivers outlined below, second-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 second-quarter 2021 net loss of $113 million. This is compared to an adjusted net loss of $84 million in the second quarter of 2020, a decrease of $0.04 per share, excluding share dilution of -$0.01 per share. Lower quarterly results at Other were primarily due to higher income tax expense (-$0.05 per share), partially offset by lower financing costs (+$0.01 per share).
Effective tax rate
Duke Energy's consolidated reported effective tax rate for the second quarter of 2021 was 4.9% compared to 26.2% in the second quarter of 2020. The decrease in the effective tax rate was primarily due to the impact of the cancellation of the ACP investment in the prior year.
The effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items for the second quarter of 2021 was 8.2% compared to 6.7% in the second quarter of 2020. The increase was primarily due to lower state tax expense 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.

Special Items and Non-GAAP Reconciliation
The following tables present a reconciliation of GAAP reported earnings (loss) per share to adjusted earnings per share for second-quarter 2021 and 2020 financial results:
(In millions, except per share amounts) After-Tax Amount 2Q 2021 Earnings per Share 2Q 2020 (Loss) Earnings per Share
Earnings (loss) per share, as reported $ 0.96 $ (1.13)
Adjustments to reported earnings (loss) per share:
Second Quarter 2021
Gas Pipeline Investments $ 12 0.01
Workplace and Workforce Realignment 135 0.18
Second Quarter 2020
Gas Pipeline Investments $ 1,626 2.21
Total adjustments $ 0.19 $ 2.21
EPS, adjusted $ 1.15 $ 1.08
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.
•Workplace and Workforce Realignment represents costs attributable to business transformation, including long-term real estate strategy changes and workforce realignment.


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 (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.
