CHARLOTTE, N.C., July 29, 2025 /PRNewswire/ -- Duke Energy (NYSE:DUK) today announced it reached an agreement to sell its Piedmont Natural Gas Tennessee local distribution company business for $2.48 billion in cash to Spire Inc. ("Spire") – one of the largest publicly traded natural gas companies in the country.

The sale price represents a 1.8x multiple of 2024 year-end rate base and a 24x multiple of 2024 earnings – a significant premium to Duke Energy's common stock. Approximately $800 million of the proceeds will be used to offset debt at Piedmont Natural Gas to maintain its capital structure, and Duke Energy expects to utilize existing tax credits to offset a majority of the cash taxes resulting from the transaction. The remaining net proceeds of $1.5 billion will help efficiently fund Duke Energy's $83 billion five-year capital plan – a plan that is focused on energy modernization investments to deliver value for customers and shareholders.

The transaction is subject to customary closing conditions, including regulatory approval by the Tennessee Public Utility Commission and the expiration or termination of the waiting period under the Hart-Scott-Rodino Act. The sale is expected to close in the first quarter of 2026.
