Duke Energy reports third-quarter 2024 financial results
▪Third-quarter 2024 reported EPS of $1.60 and adjusted EPS of $1.62
▪Company restores 5.5 million outages from historic storm season
▪Robust economic development and population migration continue to support long-term growth
CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced third-quarter 2024 reported EPS of $1.60, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $1.62. This is compared to reported EPS of $1.59 and adjusted EPS of $1.94 for the third quarter of 2023.
Adjusted EPS excludes the impact of certain items that are included in reported EPS. The difference between third-quarter 2024 reported and adjusted EPS includes costs related to the redemption of preferred securities and certain system post-implementation costs as well as results of discontinued operations.
Lower third-quarter 2024 adjusted results were driven by a higher effective tax rate, storm costs, interest expense and depreciation on a growing asset base. These items were partially offset by growth from rate increases and riders.
The company is reaffirming its 2024 adjusted EPS guidance range of $5.85 to $6.10 and trending to the lower half of the range. The company is reaffirming its long-term adjusted EPS growth rate of 5% to 7% through 2028 off the 2024 midpoint of $5.98. Management does not forecast reported GAAP EPS and related long-term growth rates.
“I am proud of the remarkable response from our employees and utility partners to a historic storm season, including three consecutive hurricanes," said Lynn Good, Duke Energy chair and chief executive officer. "Our team’s commitment to our customers was unwavering as they worked around the clock to restore 5.5 million outages as quickly and safely as possible and rebuilt large portions of our system in a matter of days.”
“We’ve continued to build on our track record of constructive regulatory outcomes and are well positioned for a strong finish to the year. Our simplified, fully regulated portfolio of Midwest and Southeast utilities operating in growing jurisdictions will continue to create long-term value for our customers, communities and shareholders.”

Business segment results
In addition to the following summary of third-quarter 2024 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 2024 segment income of $1,451 million, compared to reported segment income of $1,447 million in the third quarter of 2023. In addition to the drivers outlined below, third-quarter 2024 results include the net impact of charges related to certain system post-implementation costs, which was treated as a special item and excluded from adjusted earnings.
On an adjusted basis, Electric Utilities and Infrastructure recognized third-quarter 2024 segment income of $1,464 million, compared to adjusted segment income of $1,531 million in the third quarter of 2023. This represents a decrease of $0.09 per share. Lower quarterly results were primarily due to higher O&M expenses, including storm costs, depreciation on a growing asset base, interest expense and milder weather, partially offset by growth from rate increases and riders as well as higher sales volumes.
Gas Utilities and Infrastructure
On a reported basis, Gas Utilities and Infrastructure recognized third-quarter 2024 segment loss of $25 million, compared to reported segment income of $15 million in the third quarter of 2023. In addition to the drivers outlined below, third-quarter 2024 results include the net impact of charges related to certain system post-implementation costs, which was treated as a special item and excluded from adjusted earnings.
On an adjusted basis, Gas Utilities and Infrastructure recognized third-quarter 2024 segment loss of $22 million, compared to adjusted segment income of $15 million in the third quarter of 2023. This represents a decrease of $0.04 per share. Lower quarterly results were primarily due to higher depreciation and interest.
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 2024 segment loss of $222 million, compared to reported segment loss of $59 million in the third quarter of 2023.

Duke Energy News Release 3
On an adjusted basis, Other recognized a third-quarter 2024 segment loss of $206 million, compared to adjusted segment loss of $59 million in the third quarter of 2023. This represents a decrease of $0.19 per share. Lower quarterly results were primarily due to a higher effective tax rate.
Effective tax rate
Duke Energy's consolidated reported effective tax rate for the third quarter of 2024 was 11.2% compared to 2.8% in the third quarter of 2023. The increase in the effective tax rate was primarily due tax efficiency efforts in the prior year and a decrease in the amortization of excess deferred taxes.
Duke Energy's consolidated adjusted effective tax rate was 11.6% for the third quarter of 2024 compared to 3.9% in the third quarter of 2023. The increase in the effective tax rate was primarily due tax efficiency efforts in the prior year and 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 adjusted effective tax rate.
Storm restoration costs
Total storm restoration costs, including capital expenditures, for hurricanes Helene, Debby and Milton are estimated to be in the range of $2.4 billion to $2.9 billion and are expected to primarily impact Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida. Total storm restorations costs will be recognized in the third and fourth quarter 2024. These estimates will change as restoration work is completed and additional information is received on actual costs incurred. The majority of the costs will be deferred for future recovery in regulatory assets on the Condensed Consolidated Balance Sheets or relate to capital projects. Recovery mechanisms are in place for each subsidiary registrant and each are considering and executing on all available avenues as quickly as possible to recover storm-related costs, including insurance recovery and the securitization for certain costs, where applicable. Duke Energy Carolinas, Duke Energy Progress and Duke Energy Florida have entered into term loan facilities intended to meet incremental financing needs for a total of $1.75 billion, with an ability to increase the facilities an additional $0.85 billion.

Non-GAAP financial measures
Management evaluates financial performance in part based on non-GAAP financial measures, including adjusted earnings, adjusted EPS and adjusted effective tax rate. Adjusted earnings and adjusted EPS represent income (loss) from continuing operations available to Duke Energy Corporation common stockholders in dollar and basic per share amounts, adjusted for the dollar and per share impact of special items. The adjusted effective tax rate is calculated using pretax earnings and income tax expense, both adjusted to include the impact of noncontrolling interests and preferred dividends and to exclude the impact of 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 the adjusted effective tax rate 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.

Duke Energy News Release 5
Special items included in the periods presented include the following items, which management believes do not reflect ongoing costs:
•System post-implementation costs represents the net impact of charges related to nonrecurring customer billing adjustments as a result of implementation of a new customer system.
•Preferred redemption costs represents charges related to the redemption of Series B Preferred Stock.
•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.
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.

(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.
