Spire Inc. (SR - Free Report) recently revealed that it has acquired the Piedmont Natural Gas business in Tennessee from Duke Energy (DUK - Free Report) for $2.48 billion, with the buyout completed on March 31, 2026.
How Will the Buyout Benefit SR Stock?
The acquisition establishes Spire Tennessee as the largest investor-owned natural gas utility in the state, giving the company a stronger foothold in one of the fastest-growing regions. Serving more than 200,000 customers across the Nashville metro area and nearby communities, the business also adds nearly 3,800 miles of transmission and distribution pipelines to Spire’s network.
This expansion strengthens Spire’s regulated utility footprint and complements its operations in Missouri, Alabama and Mississippi. With Tennessee being one of the fastest-growing regions in the United States, the company is well-positioned to benefit from rising energy demand and steady customer additions over time.
The buyout aligns with Spire’s strategy of investing in regulated assets that deliver predictable returns. Spire Tennessee is expected to account for about 20% of its capital investment plan through 2030, supporting infrastructure upgrades and system improvements. Spire expects to invest roughly $4.8 billion during 2026-2030.
Supported by a constructive regulatory environment, the acquisition is expected to help Spire achieve its long-term adjusted earnings per share (EPS) growth target of 5-7% while enhancing revenue visibility and overall growth potential.
