Item 8.01.

Other
Events.

As previously disclosed, on August 14, 2025,
Duke Energy Carolinas, LLC (“ Duke Energy Carolinas ”) and Duke Energy Progress, LLC (“ Duke Energy Progress ,”
and together with Duke Energy Carolinas, the “ Companies ”) filed a joint application with the North Carolina Utilities
Commission (“ NCUC ”) and the Public Service Commission of South Carolina (“ PSCSC ”) for approval
to combine utilities, by which Duke Energy Progress will merge into Duke Energy Carolinas, resulting in a single electric utility serving
the Companies’ North Carolina and South Carolina service territories. Duke Energy Corporation, together with the Companies,
also filed an application with the Federal Energy Regulatory Commission (the “ FERC ”) on the same day. In connection
with the utility combination (the “ Combination ”), and immediately prior thereto, Duke Energy Corporation expects to
contribute its 100% equity interest in Duke Energy Carolinas to Progress Energy, Inc. (“ Progress Energy ”).

The
targeted effective date is January 1, 2027. On January 30, 2026, the FERC issued an order authorizing the Combination as consistent
with the public interest. Additionally, on April 30, 2026, the PSCSC voted to approve the Combination, and on May 1, 2026,
the NCUC issued an order approving the Combination. The effectuation of the Combination remains subject to approval by the boards
of directors of both Companies and the board of directors of Progress Energy, to the entry by the Companies, Progress Energy and Duke
Energy Corporation into a definitive agreement governing the Combination and to the satisfaction of other conditions.

Duke Energy Carolinas is filing this Current
Report on Form 8-K solely to provide certain information relating to the proposed Combination. Additionally, Duke Energy Carolinas
is providing certain supplemental risk factors related to the proposed Combination, which are filed as Exhibit 99.4 and incorporated
herein by reference.

Exhibit 99.4

Supplemental Risk Factors

Unless these supplemental risk factors indicate
otherwise, or the context otherwise requires, references to the term “Duke Energy Carolinas” means Duke Energy Carolinas,
LLC and “Duke Energy Progress” means Duke Energy Progress, LLC. Capitalized terms used but not defined herein have the meanings
ascribed to them in the Current Report on Form 8-K to which these supplemental risk factors are attached as Exhibit 99.4 (the
“Financial Statement Form 8-K”).

Risks Related to the Combination

Duke Energy Carolinas is subject to risk of
the Combination having an adverse impact on its credit rating, both while the Combination is pending and following completion of the Combination.

Duke Energy Carolinas cannot be assured that its
credit ratings will not be lowered as a result of the Combination or for any other reason. Any reduction in Duke Energy Carolinas’s
credit ratings, or the criteria used by rating agencies to determine such ratings, could adversely affect its access to capital, its cost
of capital and its other operating costs, and its ability to refinance or repay Duke Energy Carolinas’s existing debt and complete
new financings, which could have a material adverse effect on Duke Energy Carolinas’s business, financial condition, results of
operations or the trading price of its securities.

Duke Energy Carolinas will incur significant
costs in connection with the Combination.

Duke Energy Carolinas expects to incur significant
costs associated with the Combination, including costs of combining the operations of the two companies. Additional unanticipated costs
also may be incurred in the integration of the businesses of Duke Energy Carolinas and Duke Energy Progress. Any net benefit from any
anticipated elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses,
may not be achieved in the near term or at all. The failure to achieve the anticipated benefits and efficiencies from the Combination,
or the incurrence of additional expenses, could have a material adverse impact on the results of operations of the combined company.

The unaudited pro forma condensed combined
financial information included in the Financial Statement Form 8-K does not purport to be, and likely is not, representative of the
combined results of Duke Energy Carolinas and Duke Energy Progress after the Combination .

The unaudited pro forma condensed combined financial
information in the Financial Statement Form 8-K is presented for informational purposes only. It does not purport to be indicative
of the financial position or results of operations that would have actually occurred had the Combination been completed at or as of the
dates indicated, nor is it indicative of the combined company’s future operating results or financial position. The unaudited pro
forma condensed combined financial information in the Financial Statement Form 8-K does not reflect future events that may occur
after the closing of the Combination, including the potential realization of operating efficiencies or costs related to the Combination,
and does not consider potential market conditions on revenues or expenses. The unaudited pro forma condensed combined financial information
in the Financial Statement Form 8-K is based in part on certain assumptions regarding the Combination that Duke Energy Carolinas
believes are reasonable under the circumstances. Duke Energy Carolinas cannot assure you that its assumptions will prove to be accurate
over time.

The failure to integrate the businesses and
operations of Duke Energy Carolinas and Duke Energy Progress successfully in the expected time frame may adversely affect the combined
company’s future results.

Duke Energy Carolinas and Duke Energy Progress
have operated and, until the completion of the Combination, will continue to operate as separate utilities. Following the completion of
the Combination, their respective businesses will need to be integrated successfully. The process of integration may reveal that benefits
and efficiencies are less than anticipated and may result in additional expenses, all of which could reduce the anticipated benefits of
the Combination. Furthermore, it is possible that the integration process could result in inconsistencies in standards, controls, procedures
and policies, potential unknown liabilities and unforeseen expenses, delays, or regulatory conditions associated with and following completion
of the Combination; or higher-than-expected integration costs and an overall post-completion integration process that takes longer than
originally anticipated.

Each of Duke Energy Carolinas and Duke Energy
Progress has substantial amounts of indebtedness. Consequently, the combined company will have substantial indebtedness following the
Combination.

The combined company’s debt service obligations
could have an adverse impact on its earnings and cash flows for as long as the indebtedness is outstanding. For example, it could:

• make it more difficult for the combined
company to pay or refinance its debts as they become due during adverse economic and industry conditions because any decrease in revenues
could cause the combined company to not have sufficient cash flows from operations to make its scheduled debt payments;

• require a substantial portion of the combined
company’s cash flows from operations to be used for debt service payments, thereby reducing the availability of its cash flow to
fund working capital, capital expenditures, strategic transactions and other general corporate purposes;

• result in a downgrade in the rating of
the combined company’s indebtedness, which could limit its ability to borrow additional funds or increase the interest rates applicable
to its indebtedness;

• limit the flexibility of the combined
company in planning for or reacting to changes in its business and the industry in which it operates; or

• increase the exposure of the combined company
to a rise in interest rates, which would generate greater interest expense, or increase the costs of obtaining applicable interest rate
fluctuation hedges.

There can be no assurance that the combined company
will be able to repay or refinance such borrowings and obligations.

The combined company may fail to realize all
of the anticipated benefits of the Combination.

The success of the Combination will depend, in
part, on Duke Energy Carolinas’s ability to realize the anticipated benefits and cost savings from combining Duke Energy Carolinas’s
and Duke Energy Progress’s businesses and operational synergies. The anticipated benefits and cost savings of the Combination may
not be realized fully or at all, may take longer to realize than expected, may not be realized or could have other adverse effects that
Duke Energy Carolinas does not currently foresee. Some of the assumptions that Duke Energy Carolinas and Duke Energy Progress have made,
such as the achievement of the anticipated benefits related to the expected size, scale and financial strength of the combined company,
may not be realized. In addition, there could be potential unknown liabilities and unforeseen expenses associated with the Combination
that could adversely impact the combined company.

The combined company’s ability to realize
anticipated benefits is also subject to regulatory frameworks requiring the development and application of methodologies to measure and
track such benefits over time. These methodologies and outcomes may be subject to ongoing regulatory review and oversight, and failure
to achieve specified benefit levels could require additional actions, including potential financial contributions, as determined by applicable
regulatory authorities.

The future results of the combined company
following the Combination will suffer if the combined company does not effectively manage its expanded operations.

Following the Combination, the size, geographic
footprint and complexity of the combined company will increase significantly compared to the business of each of Duke Energy Carolinas
and Duke Energy Progress. The combined company’s future success will depend, in part, upon its ability to manage this expanded business.
The combined company may also face increased scrutiny from regulators and governmental authorities as a result of the significant increase
in the size, geographic footprint and complexity of its business. There can be no assurances that the combined company will be successful
or that it will realize the expected operating efficiencies, cost savings or other benefits currently anticipated from the Combination.

Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL
INFORMATION

Introduction

Duke Energy Carolinas, LLC ("Duke Energy Carolinas")
and Duke Energy Progress, LLC ("Duke Energy Progress") have operated as separate regulated utilities since the 2012 merger of
Duke Energy Corporation ("Duke Energy") and Progress Energy, Inc. ("Progress Energy") (the “2012 Merger”).
The proposed combination represents an internal reorganization of entities under common control (the "Combination") and is intended
to combine the operations of these utilities into a single regulated utility legal entity. The Combination is expected to result in a
single regulated utility operating in North Carolina and South Carolina, with a targeted effective date of January 1, 2027.

Duke Energy Carolinas and Duke Energy Progress are separate
regulated utility subsidiaries of Duke Energy serving customers in North Carolina and South Carolina. Each utility serves distinct service
territories within these states and is responsible for the generation, transmission, distribution, and sale of electricity to residential,
commercial, industrial, and wholesale customers.

The Combination represents
a transaction between entities under common control and is expected to be accounted for in accordance with Accounting Standards Codification
("ASC") 805-50, rather than as a business combination under ASC 805-10. Duke Energy has maintained continuous control over
both utilities since 2012, and the transaction does not result in a change in ultimate ownership or control.

Pursuant the transaction structure, Duke Energy will contribute
ownership of Duke Energy Carolinas to Progress Energy, a subsidiary of Duke Energy, after which Duke Energy Progress, a subsidiary of
Progress Energy, will merge with and into Duke Energy Carolinas, with Duke Energy Carolinas surviving the Combination as a subsidiary
of Progress Energy. Following the Combination, Duke Energy’s regulated electric utility operations in North Carolina and South Carolina
will be organized under Duke Energy Carolinas, including the generation, transmission, distribution, and sale of electricity to residential,
commercial, industrial, and wholesale customers.

Additional Information Related to the Unaudited Pro Forma
Condensed Combined Financial Information

The unaudited pro forma condensed
combined financial information has been prepared based on the historical financial statements of Duke Energy Carolinas and Duke Energy
Progress, as adjusted to give effect to the Combination. In accordance with ASC 805-50, assets and liabilities transferred between
entities under common control are accounted for at the historical cost basis of the common parent.

The unaudited pro forma condensed combined balance sheet
as of March 31, 2026 gives pro forma effect to the Combination as if it had occurred on March 31, 2026. The unaudited pro forma
condensed combined statements of operations for the years ended December 31, 2025, 2024, and 2023, and for the three months ended
March 31, 2026, give effect to the Combination as if it had occurred on January 1, 2023.

The unaudited pro forma
condensed combined financial information has been derived from and should be read in conjunction with: (i) the accompanying
notes to the unaudited pro forma condensed combined financial information; (ii) the historical audited consolidated financial
statements of Duke Energy Carolinas and Duke Energy Progress as of December 31, 2025 and 2024, and for the years ended
December 31, 2025, 2024, 2023, and the accompanying notes; and (iii) the historical unaudited condensed consolidated
financial statements of Duke Energy Carolinas and Duke Energy Progress as of March 31, 2026 and December 31, 2025, and for the three
months ended March 31, 2026 and 2025, and the accompanying notes.

The unaudited pro forma
condensed combined financial information is provided for illustrative purposes only and is not necessarily indicative of the results
of operations or financial position that would have been achieved had the Combination occurred on the dates indicated, nor is it
indicative of the future results of operations or financial position of the combined company. The transaction accounting adjustments
are based on information currently available and on assumptions described in the accompanying notes to the unaudited pro forma
condensed combined financial information. The unaudited pro forma condensed combined financial information does not include the
realization of any costs savings from operating efficiencies, synergies or other activities, or the recognition of any cost
increases or dis-synergies that might result from the Combination. Actual results may differ materially
from those reflected in the pro forma information.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

1.

Basis of Pro Forma Presentation

The unaudited pro forma condensed combined financial information has
been prepared in accordance with Article 11 of Regulation S-X, as amended by the final rule, Release No. 33-10786, Amendments
to Financial Disclosures about Acquired and Disposed Businesses. Under these rules, pro forma information is required to present adjustments
that reflect the accounting for the transaction (“Transaction Accounting Adjustments”)

The pro forma adjustments reflected in the unaudited pro forma condensed
combined financial information are based on currently available information and assumptions management considered reasonable under the
circumstances. The adjustments are described in the accompanying notes and may be revised as additional information becomes available
and is evaluated. Accordingly, the actual adjustments may differ from the pro forma adjustments, and such differences may be material.

The unaudited pro forma condensed combined financial information is
intended to present the significant effects of the Combination and reflects adjustments that are appropriately applied in accordance with
Article 11 of Regulation S-X.

2.

Accounting Treatment for the Merger

Although the Combination will be effected as a legal reorganization,
it is expected to be accounted for as a transaction between entities under common control in accordance with U.S. generally accepted accounting
principles and not as a business combination under ASC 805. Duke Energy is expected to contribute ownership of Duke
Energy Carolinas to Progress Energy, a subsidiary of Duke Energy, after which Duke Energy Progress will merge with and into Duke Energy
Carolinas.

Following the Combination, the regulated electric utility operations
of Duke Energy in North Carolina and South Carolina will be organized under Progress Energy and Duke Energy Carolinas.

Under common control accounting, the assets and liabilities of Duke Energy Carolinas and Duke Energy Progress are expected to be recorded
at their historical carrying amounts. Accordingly, no new goodwill or other intangible assets will be recognized as a result of the Combination,
and no gain or loss will be recorded. Existing goodwill attributable to Duke Energy Progress from prior purchase accounting is reflected
and carried forward.

In connection with the Combination, Duke Energy Carolinas is expected to reflect the effects of pushdown accounting related to the 2012
Merger, which were previously only recognized in Duke Energy's consolidated financial statements. As a result, the assets and liabilities
of the combined company reflect the historical purchase accounting adjustments recorded by Duke Energy, including goodwill attributable
to Duke Energy Progress that is carried forward (i.e., not newly recognized) as part of the Combination. There are no material impacts
to the pro forma condensed combined statements of operations resulting from the historical purchase accounting adjustments; accordingly,
no pro forma adjustments have been recorded to reflect such impacts.

The pro forma adjustments are based on currently available information
and assumptions that are factually supportable and directly attributable to the Combination and do not reflect the costs of any integration
activities or the benefits of potential future revenue growth or operational synergies.

3.

Transaction Accounting Adjustments

The following adjustments in the unaudited pro forma condensed combined
balance sheet and statements of operations reflect the impact of adjustments that are directly attributable to the Combination. The unaudited
pro forma condensed combined balance sheet as of March 31, 2026, gives pro forma effect to the Combination as if it had occurred
on March 31, 2026. The unaudited pro forma condensed combined statements of operations for the years ended December 31, 2025,
2024, and 2023, and for the three months ended March 31, 2026, give effect to the Combination as if it had occurred on January 1,
2023.

(a)

Represents the elimination of intercompany balances and transactions between Duke Energy Carolinas and Duke Energy Progress, primarily
intercompany receivables and payables, electricity sales, purchased power and intercompany interest.

(b)

Represents prior purchase accounting adjustments related to debt with respect to the Duke Energy Progress business
originating from the 2012 Merger. These adjustments affect noncurrent regulatory assets and long-term debt.

(c)

Represents prior purchase accounting adjustments related to asset retirement obligations with respect to the Duke Energy Progress
business originating from the 2012 Merger. These adjustments affect noncurrent regulatory assets and long-term asset retirement obligations.

(d)

The 2012 Merger created goodwill of $12,469 million at Duke Energy, of which $8,358 million was attributable to Duke Energy
Progress. The goodwill represents a basis difference between the net assets of Duke Energy Progress and Duke Energy's basis in Duke
Energy Progress and accordingly, the goodwill balance of $8,358 million is transferred as part of the Combination. As a result, the
combined entity reflects the historical goodwill attributed to Duke Energy Progress, and no new goodwill will be recognized as part
of the Combination.
