Duke Energy reports first-quarter 2023 financial results

▪First-quarter 2023 reported EPS of $1.01 and adjusted EPS of $1.20

▪Results reflect mild winter weather, among the warmest on record and $0.22 below normal

▪Commercial Renewables sale process in late stage

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced first-quarter 2023 reported EPS of $1.01, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.20. This is compared to reported EPS of $1.08 and adjusted EPS of $1.29 for the first quarter of 2022.

Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between the first-quarter 2023 reported and adjusted EPS included an estimated impairment on the sale of the Commercial Renewables business.

Lower first-quarter 2023 adjusted results were driven by unfavorable weather, higher interest expense, and lower volumes. These items were partially offset by growth from riders and other retail margin, lower storm costs, and favorable rate case impacts.

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're making great progress on our strategy across our entire service territory, meeting our commitments and advancing investments in a balanced way to better serve our customers,” said Lynn Good, Duke Energy chair, president and chief executive officer. "From grid improvements, to adding renewables, to advancing policy, we're taking collective action to transform and ready the system for a zero-carbon future."

“We’re responding to warm winter weather in the first quarter through disciplined cost management and other agility measures. With three quarters remaining, including our strongest quarter ahead, we are reaffirming our 2023 EPS guidance range of $5.55 to $5.75. We're also on track to deliver our long-term growth rate of 5% to 7% through 2027, off the midpoint of the 2023 range.”

Business segment results

In addition to the following summary of first-quarter 2023 business segment performance, comprehensive tables with detailed EPS drivers for the first quarter compared to prior year are provided at the end of this news release.

The discussion below of first-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 first-quarter 2023 segment income of $791 million, compared to reported and adjusted segment income of $723 million and $896 million, respectively, in the first quarter of 2022. On an adjusted basis, this represents a decrease of $0.14 per share. Lower quarterly results were primarily due to unfavorable weather, lower volumes and higher interest expense, partially offset by lower storm costs, 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 first-quarter 2023 segment income of $287 million, compared to reported and adjusted segment income of $254 million in the first quarter of 2022. On an adjusted basis, this represents an increase of $0.04 per share. Higher quarterly results were primarily driven by growth from riders and other retail margin.

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 first-quarter 2023 segment loss of $168 million, compared to reported and adjusted segment loss of $171 million in the first quarter of 2022. On an adjusted basis, this represents an increase of $0.01 per share. Higher quarterly results were primarily due to higher returns on investments, partially offset by higher interest expense.

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 in the second half of 2023.

For the first quarter of 2023, 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 $175 million.

Duke Energy News Release    3

Effective tax rate

Duke Energy's consolidated reported effective tax rate for the first quarter of 2023 was 13.8% compared to 2.9% in the first quarter of 2022. The increase in the effective tax rate was primarily due to 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 first quarter of 2023 was 14.2% compared to 8.0% in the first 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    4

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 represents the net impact of charges related to the 2022 Indiana Supreme Court ruling on coal ash.

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.

Duke Energy News Release    5

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.

(a)    Piedmont has a margin decoupling mechanism in North Carolina, weather normalization mechanisms in South Carolina and Tennessee and fixed-price contracts with most power generation customers that significantly eliminate the impact of throughput changes on earnings. Duke Energy Ohio's rate design also serves to offset this impact.
