Rhea-AI Filing Summary

Duke Energy and its subsidiary Piedmont Natural Gas completed the sale of Piedmont’s Tennessee natural gas local distribution business to Spire for $2.48 billion in cash, subject to customary purchase price adjustments. The sale closed on March 31, 2026 under a previously disclosed Asset Purchase Agreement.

Piedmont’s unaudited pro forma 2025 statement of operations shows total operating revenues of $1.911 billion and net income of $887 million after giving effect to the transaction, reflecting an estimated gain of about $693 million. Pro forma adjustments include eliminating the Tennessee business, repaying $800 million of company debt and recognizing related tax effects.

Duke Energy’s press release explains that approximately $800 million of proceeds will reduce Piedmont debt, while about $1.5 billion of net proceeds will help fund a $103 billion, five‑year regulated capital investment plan to meet growing energy demand and manage customer costs.

Insights

Large non-core asset sale funds a sizable regulated capex plan.

Duke Energy has monetized its Tennessee Piedmont Natural Gas business for $2.48 billion in cash, using about $800 million to repay Piedmont debt and roughly $1.5 billion net of tax to support a $103 billion five-year regulated capital program.

For Piedmont, the unaudited pro forma 2025 results show operating revenues of $1.911 billion and net income of $887 million, including an estimated gain of about $693 million on the sale. The business sold does not qualify as a discontinued operation, so it remains within continuing operations presentation.

The deal shifts assets and cash but keeps primary utility operations focused on the Carolinas, Florida, the Midwest and Carolinas/OH-KY gas regions. Actual long-term impact will depend on execution of the five-year capital plan and regulatory treatment of that $103 billion investment program in future rate cases.

Asset Purchase Agreement financial
"Piedmont entered into an Asset Purchase Agreement by and between Piedmont and Spire Tennessee Inc."
An asset purchase agreement is a legal contract in which a buyer agrees to buy specific assets and contracts of a business rather than buying the company’s stock or ownership. It matters to investors because it determines exactly what is being bought and what liabilities stay behind — like buying the furniture and equipment from a store but not the building or past debts — which affects the deal’s value, taxes and future risk exposure.
unaudited Pro Forma Consolidated Financial Statements financial
"The Transaction is considered significant to the Company and is therefore reflected in these unaudited Pro Forma Consolidated Financial Statements."
Regulation S-X Article 11 regulatory
"The unaudited Pro Forma Consolidated Financial Statements have been prepared in accordance with Regulation S-X Article 11, Pro Forma Financial Information."
discontinued operation financial
"The Transaction does not qualify as a discontinued operation as it does not represent a strategic shift"
A discontinued operation is a part of a company that has been sold, closed, or is planned to be shut down, and will no longer be part of its ongoing business activities. For investors, it matters because it can significantly affect a company's financial results and future outlook, similar to removing a large, ongoing project from a company's operations. Recognizing discontinued operations helps investors better understand a company's current performance separate from parts that are no longer active.
forward-looking statements regulatory
"This document includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

SELECTED UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA

 

On July 27, 2025, Piedmont Natural Gas Company, Inc (the “Company”, "PNG", and “our”) entered into a purchase agreement (“Purchase Agreement”) with Spire, Inc., for the sale (the “Transaction”) of our Piedmont Tennessee business ("PNG TN") with expected proceeds of $2.48 billion, subject to closing adjustments, with proceeds due at closing. The Company completed the sale on March 31, 2026. The Transaction is considered significant to the Company and is therefore reflected in these unaudited Pro Forma Consolidated Financial Statements.

 

The unaudited Pro Forma Consolidated Financial Statements have been derived from the Company’s historical consolidated financial statements ("PNG Historical") and give effect to the Transaction. The following unaudited Pro Forma Consolidated Statement of Operations for the year ended December 31, 2025 reflects the Company’s results as if the Transaction had occurred as of January 1, 2025. The following unaudited Pro Forma Consolidated Balance Sheet as of December 31, 2025 reflects the Company’s financial position as if the Transaction had occurred on December 31, 2025.

NOTES TO THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

 

Transaction Accounting Adjustments to Pro Forma Consolidated Financial Statements:

 

(a) Adjustments represent the elimination of assets, liabilities, and results of operations of the Piedmont Tennessee business.

 

(b) Reflects $2.48 billion of estimated cash consideration from the disposal of the Piedmont Tennessee business less repayment of debt noted in (c) and estimated payment for taxes as noted in (e).

 

(c) Reflects cash used for repayment of the Company’s debt of $800 million. Unamortized debt expenses were immaterial.

 

(d) Reflects accrual for non-recurring costs of approximately $37 million incurred after December 31, 2025, to complete the Transaction. These costs primarily relate to transaction advisory and professional fees associated with the Transaction.

 

(e) Reflects estimated current Income tax accrued and Deferred tax expense due to the recognition of the taxable gain resulting from the Transaction. Adjustments include $347 million offset to cash representative of decrease in accumulated deferred income tax and taxes accrued.

 

(f) Reflects the estimated gain recognized from the Transaction. The estimated gain was computed by taking the total consideration of $2.48 billion, less the amount of net assets sold of $1.74 billion and $50 million estimated transaction costs associated with the Transaction. The actual gain will be calculated based on the net book value as of the closing of the Transaction and therefore could differ from the current estimate. The total consideration received is subject to customary post-closing adjustments.

 

(g) Reflects the elimination of the related Interest expense of $22 million for the twelve months ended December 31, 2025 to give effect to the repayment of debt.

 

(h) Reflects the income tax effect of the pro forma adjustments calculated using the applicable statutory tax rates in effect within the respective tax jurisdictions during the periods presented. The estimated federal and state statutory income tax rate is 24%.

 

(i) Amounts relate to adjustments to retained earnings due to gain on sale, tax impact of the gain on sale, interest expense, transaction costs, and corporate allocation costs.

 

(j) Adjustment to Accounts payable to affiliated companies of $37 million reflects corporate allocations for the proportionate share of corporate governance and other shared services costs, primarily related to shared support functions, office supplies, rent, as well as other third-party costs, indemnification coverages, and usage of shared office space.

 

(k) Reflects the reclassification of transaction costs of $13 million incurred prior to December 31, 2025, to offset the gain on sale.

Duke Energy completes sale of its Tennessee Piedmont Natural Gas business to Spire

 

·Close of transaction previously announced in July 2025
·Proceeds to help fund industry’s largest regulated capital plan

 

CHARLOTTE, N.C. – Duke Energy (NYSE: DUK) today announced it has completed the sale of its Tennessee Piedmont Natural Gas business to Spire – one of the largest publicly traded natural gas companies in the country – for $2.48 billion. The agreement was previously announced on July 29, 2025.

 

Approximately $800 million of the proceeds will be used to pay down debt at Piedmont Natural Gas to maintain its capital structure. The remaining $1.5 billion proceeds, net of tax, will help efficiently fund the industry’s largest regulated capital plan – $103 billion of investments over the next five years – to support a growing system and serve increasing load while keeping customer costs as low as possible.

 

“Today marks a significant milestone with the successful transition of our Tennessee natural gas business to Spire,” said Harry Sideris, Duke Energy president and chief executive officer. “As we enter a period of record investment, this transaction helps efficiently fund our capital plan – a plan built on safely and reliably meeting our communities’ growing energy needs while managing costs for our more than 10 million customers.”

 

Sideris added, “I want to thank our Tennessee natural gas teammates for their commitment to industry-leading customer service, safety and operational excellence, as well as the Nashville community for trusting us to serve its growing energy needs for more than 40 years.

FAQ

What transaction did Duke Energy (DUK) report in this Form 8-K?

Duke Energy reported that its subsidiary Piedmont Natural Gas completed the sale of its Tennessee natural gas local distribution business to Spire for $2.48 billion in cash. The deal closed on March 31, 2026 under a previously disclosed Asset Purchase Agreement.

How will Duke Energy (DUK) use the $2.48 billion in sale proceeds?

Approximately $800 million of proceeds will repay debt at Piedmont Natural Gas to maintain its capital structure. The remaining roughly $1.5 billion of proceeds, net of tax, will help fund Duke Energy’s $103 billion regulated capital investment plan over the next five years.

How does the Tennessee sale affect Piedmont’s pro forma 2025 earnings?

After the transaction, Piedmont’s unaudited pro forma 2025 net income is $887 million, up from historical $440 million, primarily due to an estimated $693 million gain on the sale. Pro forma total operating revenues decrease to $1.911 billion after removing the Tennessee operations.

Did the Tennessee natural gas sale qualify as a discontinued operation for Piedmont?

No. The company states the transaction does not qualify as a discontinued operation because it does not represent a strategic shift expected to have a major effect on Piedmont’s operations or financial results. Therefore, the sold business remains within continuing operations presentation in the pro forma statements.

What major balance sheet changes are shown in Piedmont’s pro forma data?

Piedmont’s unaudited pro forma balance sheet shows cash and cash equivalents increasing to $1.334 billion, total assets at $11.830 billion, and total equity at $5.276 billion. Adjustments include eliminating Tennessee assets, repaying $800 million of debt and recognizing related tax and transaction cost effects.

What scale of capital spending plan does Duke Energy highlight in this filing?

Duke Energy highlights a regulated capital plan of $103 billion in investments over the next five years. Management indicates that net proceeds of about $1.5 billion from the Tennessee sale will help efficiently fund this plan to support system growth while managing customer costs.
