Duke Energy reports second quarter 2018 financial results


▪	Second quarter 2018 GAAP EPS of $0.71; adjusted EPS of $0.93


▪	Company delivering on commitments as it executes on long-term strategy


▪	Company reaffirms 2018 adjusted EPS guidance range of $4.55 to $4.85

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced second quarter 2018 reported diluted earnings per share (EPS), prepared in accordance with Generally Accepted Accounting Principles (GAAP) of $0.71, compared to $0.98 for the second quarter of 2017. Duke Energy's second quarter 2018 adjusted diluted EPS was $0.93, compared to $1.01 for the second quarter of 2017. The company remains on track to achieve its earnings targets for the year.

Adjusted diluted EPS excludes the impact of certain items that are included in GAAP reported diluted EPS. The difference between second quarter 2018 GAAP reported diluted EPS and adjusted diluted EPS was primarily due to charges related to the Duke Energy Carolinas (DEC) North Carolina rate case order.

Adjusted diluted EPS for second quarter 2018 was lower than the prior year primarily due to a lower tax shield on holding company interest as a result of the Tax Cuts and Jobs Act of 2017 (Tax Act), higher depreciation from a growing asset base, and higher operation and maintenance expense (O&M) including storm costs; partially offset by warmer weather and contributions from the Duke Energy Progress (DEP) North Carolina rate case.

“Our second quarter results reinforce confidence as we deliver on our long-term strategy, creating value for customers and growth for investors,” said Lynn Good, Duke Energy chairman, president and CEO. “We have executed on our plan during the first half of the year - reaching constructive regulatory outcomes in the Carolinas, addressing tax reform impacts in our largest jurisdictions and making progress on key infrastructure investments like the Atlantic Coast Pipeline. We have the right strategy and are on track to achieve our full-year guidance for 2018.”

Business segment results

In addition to the following summary of second quarter 2018 business segment performance, comprehensive tables with detailed EPS drivers for the second quarter compared to prior year are provided in the tables at the end of this news release.

Duke Energy News Release 2

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 basis, Electric Utilities and Infrastructure recognized second quarter 2018 segment income of $575 million, compared to $729 million in the second quarter of 2017. In addition to the drivers outlined below, second quarter 2018 results were impacted by $136 million in after-tax charges primarily related to the DEC North Carolina rate case order. This amount was treated as a special item and excluded from adjusted earnings.

On an adjusted basis, Electric Utilities and Infrastructure recognized second quarter 2018 adjusted segment income of $711 million, compared to $729 million in the second quarter of 2017, a decrease of $0.03 per share.

Lower quarterly results at Electric Utilities and Infrastructure were driven by higher depreciation and amortization expense (-$0.07 per share) primarily due to a growing asset base, higher O&M expense (-$0.03 per share) including storm restoration costs, the resolution of FERC accounting matters (-$0.02 per share), and lower AFUDC equity (-$0.02 per share). These unfavorable drivers were partially offset by warmer weather (+$0.07 per share), higher rider revenues (+$0.04 per share) and the DEP rate case contribution (+$0.02 per share).

Gas Utilities and Infrastructure

On a reported and adjusted basis, Gas Utilities and Infrastructure recognized second quarter 2018 segment income of $28 million, compared to $27 million in the second quarter of 2017. As expected, results at Gas Utilities and Infrastructure were flat for the quarter, with the bulk of the remaining earnings expected to come in the fourth quarter.

Commercial Renewables

On a reported and adjusted basis, Commercial Renewables recognized second quarter 2018 segment income of $38 million, compared to $26 million in the second quarter of 2017, an increase of $0.02 per share. Higher quarterly results at Commercial Renewables were primarily due to a favorable settlement on a contractual agreement.

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 2018 net loss of $136 million, compared to a net loss of $94 million in the second quarter of 2017. In addition to the drivers outlined below, second quarter 2018 results were impacted by costs to achieve the Piedmont merger. These costs were treated as special items and excluded from adjusted earnings.

On an adjusted basis, Other recognized a second quarter 2018 adjusted net loss of $121 million, compared to an adjusted net loss of $75 million in the second quarter of 2017, a difference of $0.07 per share. Lower quarterly results at Other were primarily due to a lower

Duke Energy News Release 3

tax shield on holding company interest as a result of the Tax Act (-$0.04 per share) and higher interest expense (-$0.02 per share).

Duke Energy's consolidated reported effective tax rate for the second quarter of 2018 was 16.5% compared to 32.1% in the second quarter of 2017. The consolidated adjusted effective tax rate for second quarter 2018 was 18.4%, compared to 32.3% in 2017. The decreases in the reported and adjusted effective tax rates were primarily due to the impacts of the Tax Act. Adjusted effective tax rate is a non-GAAP financial measure. The tables at the end of this news release present a reconciliation of the reported effective tax rate to the adjusted effective tax rate.

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 diluted EPS, and adjusted effective tax rate. Adjusted earnings and adjusted diluted EPS represent income from continuing operations attributable to Duke Energy, 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 as adjusted for 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 believes the presentation of adjusted earnings, adjusted diluted EPS, and the adjusted effective tax rate provides useful information to investors, as it provides them with an additional relevant comparison of Duke Energy’s performance across periods. Management uses these non-GAAP financial measures for planning and forecasting, and for reporting financial results to the Duke Energy Board of Directors, employees, stockholders, analysts and investors. Adjusted diluted EPS is also used as a basis for employee incentive bonuses. The most directly comparable GAAP measures for adjusted earnings, adjusted diluted EPS and adjusted effective tax rate are Net Income Attributable to Duke Energy Corporation (GAAP reported earnings) and Diluted EPS Attributable to Duke Energy Corporation common stockholders (GAAP reported EPS), 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:


•	Costs to achieve Piedmont merger represent charges that result from the Piedmont acquisition.


•	Regulatory and Legislative Impacts represent charges related to rate case orders, settlements or other actions of regulators or legislative bodies.


•	Sale of Retired Plant represents the loss associated with selling Beckjord Generating Station (Beckjord), a non-regulated generating facility in Ohio.


•	Impairment of Equity Method Investment represents an other-than-temporary impairment of an investment in Constitution Pipeline Company, LLC (Constitution).


•	Impacts of the Tax Act represents an Alternative Minimum Tax (AMT) valuation allowance recognized related to the Tax Act.

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 is defined as income from continuing operations attributable to Duke Energy. Segment income includes intercompany revenues and expenses that are eliminated in the Condensed Consolidated Financial Statements. Management also uses adjusted segment

Duke Energy News Release 5

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 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 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 diluted 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.

Note: Earnings Per Share amounts are calculated using the prior year consolidated statutory income tax rate for all drivers except Commercial Renewables, which uses an effective rate.

(a) Electric Utilities and Infrastructure includes rate increases at DEP as a result of the North Carolina rate case (+$0.03) and increased rider revenues (+$0.04).
(b) Primarily due to the recovery of deferred coal ash costs from wholesale customers in the Carolinas, which is offset in depreciation (+$0.03), and charges related to the resolution of FERC accounting matters (-$0.02).
(c) Electric Utilities and Infrastructure is primarily due to higher storm costs compared to the prior year (-$0.02).
(d) Electric Utilities and Infrastructure includes lower AFUDC equity (-$0.02) and higher interest expense (-$0.01).
(e) Electric Utilities and Infrastructure is primarily due to the amortization of coal ash costs, which is partially offset in wholesale (-$0.04), higher depreciation associated with the DEP rate case (-$0.02), and other increases in depreciation and amortization (-$0.07), primarily due to a growing asset base.
(f) Includes the net earnings impact of the Tax Act, including regulatory deferrals. Electric Utilities and Infrastructure also includes a benefit related to the return of North Carolina state excess deferred income taxes as a result of the DEP rate case.

Note: Earnings Per Share amounts are calculated using the prior year consolidated statutory income tax rate for all drivers except for Commercial Renewables, which uses an effective rate.

(a) Electric Utilities and Infrastructure includes rate increases at DEP as a result of the North Carolina rate case (+$0.04) and increased rider revenues (+$0.07).
(b) Primarily due to the recovery of deferred coal ash costs from wholesale customers in the Carolinas, which is offset in depreciation (+$0.07), partially offset by charges related to the resolution of FERC accounting matters (-$0.04).
(c) Electric Utilities and Infrastructure includes lower AFUDC equity (-$0.03) and higher interest expense (-$0.01).
(d) Electric Utilities and Infrastructure is primarily due to amortization of coal ash costs, which is partially offset in wholesale (-$0.08), higher depreciation associated with the DEP rate case (-$0.02) and other increases in depreciation and amortization (-$0.11), primarily due to a growing asset base.
(e) Includes the net earnings impact of the Tax Act, including regulatory deferrals. Electric Utilities and Infrastructure also includes a benefit related to the return of North Carolina state excess deferred income taxes as a result of the DEP rate case.
