▪2024 reported EPS of $5.71 and adjusted EPS of $5.90, closing the year within guidance range

▪Constructive regulatory outcomes in 2024 support execution of strategic priorities

▪Five-year capital plan increasing to $83 billion to fund new generation and serve growing energy demand

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced 2024 full-year reported EPS of $5.71, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted EPS of $5.90. This is compared to reported and adjusted EPS of $3.54 and $5.56, respectively, for the full-year 2023.

Adjusted EPS excludes the impact of certain items that are included in reported EPS. In 2024, these included amounts related to noncore asset sales and net impairments, regulatory matters, captive storm deductible and other matters as described on pages 4 and 5.

Higher full-year 2024 adjusted results were primarily driven by growth from rate increases and riders, improved weather and higher sales volumes. These items were partially offset by higher interest expense, depreciation on a growing asset base and storm costs, along with a higher effective tax rate.

The company is introducing 2025 adjusted EPS guidance of $6.17 to $6.42 and extending its long-term adjusted EPS growth rate of 5% to 7% through 2029 off the 2025 midpoint of $6.30. Management does not forecast reported GAAP EPS and related long-term growth rates.

“Today we announced strong fourth-quarter results, closing out a year of great accomplishment,” said Lynn Good, Duke Energy chair and chief executive officer. “Duke Energy enters 2025 in a position of strength, and I’m excited about the future with Harry Sideris as its next CEO. Under his leadership, Duke Energy is well positioned to execute the next phase of our business strategy.”

“I assume this new position at a pivotal point for our company and industry,” said Duke Energy President and incoming CEO Harry Sideris. “At Duke Energy, we are committed to investing in the critical infrastructure needed to support our country’s aspirations for technology leadership and economic growth. We will deliver on these goals while maintaining energy reliability, affordability and security for our customers and growing EPS 5% to 7% through 2029.”

Duke Energy's fourth-quarter 2024 reported EPS was $1.54, compared to $1.27 for the fourth quarter of 2023. Duke Energy's fourth-quarter 2024 adjusted EPS was $1.66, compared to $1.51 for the fourth quarter of 2023. Higher adjusted results for the quarter compared to last year were primarily driven by growth from rate increases and riders. These items were partially offset by higher interest expense and depreciation on a growing asset base.

In addition to the following summary of fourth-quarter 2024 business segment performance, comprehensive tables with detailed EPS drivers for the fourth-quarter and full-year 2024 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.

On a reported basis, Electric Utilities and Infrastructure recognized fourth-quarter 2024 segment income of $1,208 million, compared to segment income of $1,135 million in the fourth quarter of 2023. In addition to the drivers outlined below, fourth-quarter 2024 results include charges related to regulatory matters, noncore asset sales and net impairments to certain joint venture electric transmission projects, which were treated as special items and excluded from adjusted earnings.

On an adjusted basis, Electric Utilities and Infrastructure recognized fourth-quarter 2024 segment income of $1,238 million, compared to segment income of $1,115 million, in the fourth quarter of 2023. This represents an increase of $0.16 per share. Higher quarterly results were primarily driven by growth from rate increases and riders, partially offset by higher depreciation on a growing asset base.

On a reported basis, Gas Utilities and Infrastructure recognized fourth-quarter 2024 segment income of $189 million, compared to segment income of $192 million in the fourth quarter of 2023. In addition to the drivers outlined below, fourth-quarter 2024 results include charges related to impairments for certain renewable natural gas investments, which were treated as a special item and excluded from adjusted earnings.

On an adjusted basis, Gas Utilities and Infrastructure recognized fourth-quarter 2024 segment income of $231 million, compared to segment income of $192 million, in the fourth quarter of 2023. This represents an increase of $0.05 per share. Higher quarterly results were primarily driven by growth from rate increases and riders, partially offset by higher interest expense and depreciation on a growing asset base.

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 2024 segment loss of $204 million, compared to a segment loss of $228 million in the fourth quarter of 2023. In addition to the drivers outlined below, fourth-quarter 2024 results include charges related to an insurance deductible for Hurricane Helene property losses, which was treated as a special item and excluded from adjusted earnings.

On an adjusted basis, Other recognized a fourth-quarter 2024 segment loss of $186 million, compared to a segment loss of $133 million in the fourth quarter of 2023. This represents a decrease of $0.06 per share. Lower quarterly results were primarily driven by higher interest expense.

Duke Energy's consolidated reported effective tax rate for the fourth quarter of 2024 was 8.1% compared to 9.7% in the fourth quarter of 2023. The decrease was primarily due to an increase in the amortization of excess deferred taxes and PTCs.

Duke Energy's consolidated adjusted effective tax rate for the fourth quarter of 2024 was 9.3% compared to 10.5% in the fourth quarter of 2023. The decrease was primarily due to an increase in the amortization of excess deferred taxes and PTCs.

The tables at the end of this news release present a reconciliation of the reported effective tax rate to the adjusted effective tax rate.

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 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, 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.

Special items included in the periods presented include the following items, which management believes do not reflect ongoing costs:

•Regulatory matters primarily represents net impairment charges related to Duke Energy Carolinas' and Duke Energy Progress' North Carolina and South Carolina rate case orders, Duke Energy Carolinas' North Carolina rate case settlement and charges related to Duke Energy Indiana post-retirement benefits.

•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.

•Noncore asset sales and net impairments primarily represents charges related to certain joint venture electric transmission projects and certain renewable natural gas investments.

•Captive Storm Deductible represents charges related to an insurance deductible for Hurricane Helene property losses.

•Organizational optimization represents costs associated with strategic repositioning to a fully regulated utility.

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 (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 (loss) 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.
