Duke Energy reports third quarter 2019 financial results


▪	Third quarter 2019 reported EPS of $1.82 and adjusted EPS of $1.79 with strong results across all segments


▪	Adjusted EPS growth of 7% year to date


▪	Company raises midpoint of 2019 adjusted EPS guidance; new range of $4.95 to $5.15


▪	Company reaffirms long-term earnings growth target of 4% to 6%

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced third quarter 2019 reported diluted earnings per share (EPS) of $1.82, prepared in accordance with Generally Accepted Accounting Principles (GAAP), and adjusted diluted EPS of $1.79. This is compared to reported and adjusted diluted EPS of $1.51 and $1.65, respectively, for the third quarter of 2018.

Adjusted diluted EPS excludes the impact of certain items that are included in reported diluted EPS. The difference between third quarter 2019 reported diluted EPS and adjusted diluted EPS was due to a reduction of an impairment charge originally recorded in 2018.

Higher third quarter 2019 adjusted results were primarily driven by growth from investments at electric and gas utilities, favorable weather and lower O&M expenses. These items were partially offset by higher financing costs and lower volumes.

Based upon the results through the third quarter, the company is raising the midpoint of and narrowing its 2019 adjusted diluted earnings guidance range to $4.95 to $5.15 per share.

“We delivered strong growth across our business segments in the third quarter and continued executing our long-term strategy to build a cleaner, smarter energy future,” said Lynn Good, Duke Energy chairman, president and CEO. "We've outlined a more aggressive climate strategy, advanced important energy infrastructure projects that will enable us to provide more value for our customers and communities and reached constructive regulatory settlements with key stakeholders.

Our results give us confidence to narrow our full-year guidance, raising the midpoint into the upper half of our original range, and reaffirm our long-term growth rate of 4% to 6% through 2023 off the midpoint of our original 2019 guidance range of $5.00.”

Business segment results

In addition to the following summary of third quarter 2019 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 reported 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 2019 segment income of $1,385 million, compared to $1,167 million in the third quarter of 2018. Third quarter 2019 reported results included the reduction of an impairment charge originally recorded in 2018. This amount was treated as a special item and excluded from adjusted earnings.

On an adjusted basis, Electric Utilities and Infrastructure recognized third quarter 2019 adjusted segment income of $1,366 million, compared to $1,175 million in the third quarter of 2018, an increase of $0.25 per share, excluding share dilution of $0.03. Higher quarterly results were primarily due to contributions from base rate changes and higher rider revenues (+$0.11 per share), favorable weather (+$0.09 per share) and lower O&M expenses (+$0.07 per share).

These results were partially offset by higher depreciation and amortization on a growing asset base (-$0.03 per share) and lower volumes (-$0.03 per share).

Gas Utilities and Infrastructure

On a reported and adjusted basis, Gas Utilities and Infrastructure recognized third quarter 2019 segment income of $26 million. This is compared to reported and adjusted earnings of $17 million and $18 million, respectively, in the third quarter of 2018.

On an adjusted basis, this represents an increase of $0.01 per share. Higher quarterly results were driven primarily by higher earnings from midstream investments.

Commercial Renewables

On a reported and adjusted basis, Commercial Renewables recognized third quarter 2019 segment income of $40 million, compared to a reported and adjusted segment (loss)/income of $(62) million and $26 million, respectively, in the third quarter of 2018. Third quarter 2018 reported results included an impairment charge resulting from annual goodwill testing. This amount was treated as a special item and excluded from adjusted earnings.

On an adjusted basis, this represents an increase of $0.02 per share. Higher quarterly results were primarily impacted by favorable wind resource and growth from new projects.

Other

Other primarily includes interest expense on holding company debt, other unallocated corporate costs and results from Duke Energy’s captive insurance company.

Duke Energy News Release 3

On a reported and adjusted basis, Other recognized a third quarter 2019 net loss of $124 million. This is compared to a reported and adjusted net loss of $44 million and $40 million, respectively, in the third quarter of 2018.

Lower quarterly results at Other were primarily due to higher financing costs related to funding various investments (-$0.05 per share), as well as timing of income tax expense in 2019 compared to 2018 (-$0.06 per share).

Effective Tax Rate

Duke Energy's consolidated reported effective tax rate for the third quarter of 2019 was 12.4% compared to 13.7% in the third quarter of 2018. The decrease in the effective tax rate was primarily due to the amortization of excess deferred taxes. The effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items for the third quarter of 2019 was 12.2% compared to 12.9% in the third quarter of 2018. The decrease was primarily due to 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.

Non-GAAP financial measures

Management evaluates financial performance in part based on non-GAAP financial measures, including adjusted earnings, adjusted diluted EPS and effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items. Adjusted earnings and adjusted diluted EPS represent income from continuing operations attributable to Duke Energy 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 believes the presentation of these non-GAAP financial measures 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 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 effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items are Net Income Attributable to Duke Energy Corporation (GAAP reported earnings), Diluted EPS Attributable to Duke Energy Corporation common stockholders (GAAP reported EPS), 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 benefits or costs:


•	Impairment Charges represents a reduction of a prior year impairment at Citrus County CC, an other-than-temporary-impairment ("OTTI") of an investment in Constitution and a Commercial Renewables goodwill impairment.


•	Costs to Achieve Piedmont Merger represents charges that resulted from the Piedmont acquisition.


•	Regulatory and Legislative Impacts represents 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 nonregulated generating facility in Ohio.


•	Impacts of the Tax Act represents an AMT valuation allowance recognized and a true up of prior year tax estimates 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 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.

Duke Energy Corporation Non-GAAP Reconciliations Third Quarter Earnings Review & Business Update November 8, 2019 Adjusted Diluted Earnings per Share (EPS) The materials for Duke Energy Corporation’s (Duke Energy) Third Quarter Earnings Review and Business Update on November 8, 2019, include a discussion of adjusted diluted EPS for the quarter and year-to-date periods ended September 30, 2019 and 2018. The non-GAAP financial measure, adjusted diluted EPS, represents diluted EPS from continuing operations attributable to Duke Energy Corporation common stockholders, adjusted for the per share impact of special items. As discussed below, special items represent certain charges and credits, which management believes are not indicative of Duke Energy’s ongoing performance. The most directly comparable GAAP measure for adjusted diluted EPS is reported diluted EPS attributable to Duke Energy Corporation common stockholders. Reconciliations of adjusted diluted EPS for the quarter and year-to-date periods ended September 30, 2019 and 2018, to the most directly comparable GAAP measures are included herein. Special items for the quarter and year-to-date periods ended September 30, 2019 and 2018, include the following items, which management believes do not reflect ongoing costs:  Impairment Charges represents a reduction of a prior-year impairment at Citrus County CC, an other- than-temporary-impairment (“OTTI”) of an investment in Constitution and a Commercial Renewables goodwill impairment.  Costs to Achieve Piedmont Merger represents charges that resulted from the Piedmont acquisition.  Regulatory and Legislative Impacts represents 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, a nonregulated generating facility in Ohio.  Impacts of the Tax Act represents an AMT valuation allowance recognized and a true up of prior-year tax estimates related to the Tax Act. Adjusted Diluted EPS Guidance The materials for Duke Energy’s Third Quarter Earnings Review and Business Update on November 8, 2019, include a reference to the forecasted 2019 adjusted diluted EPS guidance range of $4.95 - $5.25 per share, narrowed from $4.80 - $5.20 per share during the third quarter of 2019. The materials also reference the long- term range of annual growth of 4% - 6% through 2023 off the original midpoint of 2019 adjusted EPS guidance range of $5.00. Adjusted diluted EPS is a non-GAAP financial measure as it represents diluted EPS from continuing operations attributable to Duke Energy Corporation common stockholders, adjusted for the per share impact of special items (as discussed above under Adjusted Diluted EPS). Due to the forward-looking nature of this non-GAAP financial measure for future periods, information to reconcile it 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.

Adjusted Segment Income and Adjusted Other Net Loss The materials for Duke Energy’s Third Quarter Earnings Review and Business Update on November 8, 2019, include a discussion of adjusted segment income and adjusted other net loss for the quarter and year-to-date periods ended September 30, 2019 and 2018, and a discussion of 2019 forecasted adjusted segment income and forecasted adjusted other net loss. Adjusted segment income and adjusted other net loss are non-GAAP financial measures, as they represent reported segment income and other net loss adjusted for special items (as discussed above under Adjusted Diluted EPS). When a per share impact is provided for a segment income driver, the after-tax driver is derived using the pretax amount of the item less income taxes based on the segment statutory tax rate of 24% for Electric Utilities and Infrastructure and Gas Utilities and Infrastructure, segment statutory tax rate of 23% for Other, or an effective tax rate for Commercial Renewables. The after-tax earnings drivers are divided by the Duke Energy weighted average diluted shares outstanding for the period. The most directly comparable GAAP measures for adjusted segment income and adjusted other net loss are reported segment income and other net loss, which represents segment income and other net loss from continuing operations, including any special items. A reconciliation of adjusted segment income and adjusted other net loss for the quarter and year-to-date periods ended September 30, 2019 and 2018, to the most directly comparable GAAP measures is included herein. Due to the forward-looking nature of any forecasted adjusted segment income and forecasted 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 are not available at this time, as the company is unable to forecast all special items, as discussed above under Adjusted Diluted EPS guidance. Effective Tax Rate Including Impacts of Noncontrolling Interests and Preferred Dividends and Excluding Special Items The materials for Duke Energy’s Third Quarter Earnings Review and Business Update on November 8, 2019, include a discussion of the effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items for the quarter and year-to-date periods ended September 30, 2019. The materials also include a discussion of the 2019 forecasted effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items. Effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items is a non-GAAP financial measure as the rate is calculated using pretax income and income tax expense, both adjusted for the impact of special items, noncontrolling interests and preferred dividends. The most directly comparable GAAP measure is reported effective tax rate, which includes the impact of special items and excludes the impacts of noncontrolling interests and preferred dividends. A reconciliation of this non-GAAP financial measure for the quarter and year-to-date periods ended September 30, 2019, to the most directly comparable GAAP measure is included herein. Due to the forward-looking nature of the 2019 forecasted effective tax rate including impacts of noncontrolling interests and preferred dividends and excluding special items, information to reconcile it to the most directly comparable GAAP financial measure is not available at this time, as management is unable to project all special items, as discussed above under Adjusted Diluted EPS Guidance. Available Liquidity The materials for Duke Energy’s Third Quarter Earnings Review and Business Update on November 8, 2019, include a discussion of Duke Energy’s available liquidity balance. The available liquidity balance presented is a non-GAAP financial measure as it represents cash and cash equivalents, excluding certain amounts held in foreign jurisdictions and cash otherwise unavailable for operations, and remaining availability under Duke Energy’s available credit facilities, including the master credit facility. The most directly comparable GAAP financial measure for available liquidity is cash and cash equivalents. A reconciliation of available liquidity as of September 30, 2019, to the most directly comparable GAAP measure is included herein.

Core Electric and Gas Earnings per Share The materials for Duke Energy’s Third Quarter Earnings Review and Business Update on November 8, 2019, reference Core Electric and Gas Earnings per Share for the year-to-date periods ended September 30, 2019 and 2018, and December 31, 2018 and 2017. The Core Electric and Gas Earnings per Share is calculated by adding Adjusted Earnings per segment, excluding the Commercial Renewables segment, and dividing by the total weighted average shares, diluted (reported and adjusted). Core Electric and Gas Earnings per Share is a non-GAAP financial measure, as it represents reported diluted EPS adjusted for special items. Special items represent certain charges and credits, which management believes are not indicative of Duke Energy’s ongoing performance (as discussed above under Adjusted Diluted EPS). The most directly comparable GAAP measure for adjusted diluted EPS is reported diluted EPS attributable to Duke Energy Corporation common stockholders. Reconciliations of adjusted diluted EPS for the year-to-date periods ended September 30, 2019 and 2018, and December 31, 2018 and 2017, to the most directly comparable GAAP measures are included herein. Non-Rider Recoverable O&M The materials for Duke Energy’s Third Quarter Earnings Review and Business Update on November 8, 2019, include a discussion of Duke Energy’s non-rider recoverable operating, maintenance and other expenses (O&M) for the year-to-date periods ended December 31, 2018, 2017, 2016 and 2015 as well as the forecasted year-to-date period ended December 31, 2019. Non-rider recoverable O&M expenses are non- GAAP financial measures, as they represent reported O&M expenses adjusted for special items and expenses recovered through riders. The most directly comparable GAAP financial measure for non-rider recoverable O&M expenses is reported operating, maintenance and other expenses. A reconciliation of nonrecoverable O&M expenses for the year-to-date periods ended December 31, 2018, 2017, 2016, and 2015, as well as the forecasted year-to-date period ended December 31, 2019, to the most directly comparable GAAP measure are included here-in. Due to the forward-looking nature of this non-GAAP financial measure for future periods, information to reconcile it to the most directly comparable GAAP financial measure is not available at this time, as management is unable to project all special items, as discussed above under Adjusted Diluted EPS Guidance.

(b) Beginning January 1, 2018, Duke Energy adopted new accounting guidance for the presentation of net periodic costs related to benefit plans. Prior to this guidance, Duke Energy presented the total non-capitalized net periodic costs within Operation, maintenance and other expense. Retrospective application of this guidance required Duke Energy to reclassify the presentation of non-service cost (benefit) components of net periodic costs to Other income and expenses. In accordance with the transition guidance for the new accounting rules, Operations, maintenance and other expense has been recast for the years ended December 31, 2017 and 2016 and periods prior to January 1, 2016 have not required recasting. This adjustment reflects the historical impact of adopting the new accounting standard to the earliest periods presented (December 31, 2015). (c) Presented as a special item for the purpose of calculating adjusted earnings and adjusted diluted earnings per share. (d) Primarily represents expenses to be deferred or recovered through rate riders.
