SPIRE INC Material Event: Acquisition of Piedmont Natural Gas’s Tennessee Assets

Spire Inc (NYSE: SR), a utility company based in St. Louis, has officially expanded its footprint. By acquiring Piedmont Natural Gas’s Tennessee operations, Spire has grown well beyond its traditional markets in Missouri, Alabama, and Mississippi.

1. What happened?

Spire finalized the acquisition of Piedmont Natural Gas’s Nashville operations for $2.48 billion. This move establishes Spire as the largest investor-owned natural gas utility in Tennessee. The company now serves over 200,000 additional customers and manages 3,800 miles of pipeline in a high-growth region.

2. When did it happen?

The deal officially closed on March 31, 2026, following approval from the Tennessee Public Utility Commission.

3. Why does this matter for growth?

Spire is looking to outpace the growth of its older, more established utility markets. Nashville is one of the fastest-growing cities in the U.S., and this acquisition provides Spire with a steady, regulated stream of income. Management projects this deal will boost earnings per share by 5–7% annually over the next five years.

4. What this means for your investment

This acquisition significantly shifts how Spire allocates its capital:

• Infrastructure Investment: Through 2030, Spire plans to dedicate 20% of its annual budget to upgrading Tennessee’s pipelines and capacity.
• Debt Management: Spire funded this deal using a mix of new debt and equity. Investors should monitor future earnings reports closely to ensure that the costs associated with this debt do not compress profit margins.
• Regulatory Environment: Tennessee’s regulatory framework is generally favorable for utilities, allowing for the recovery of infrastructure costs from customers in a timely manner.

5. What to watch for in the coming months

• The Debt-to-Capital Ratio: Spire has committed to keeping its debt-to-capital ratio below 70%. If this ratio approaches that limit, the company may be forced to slow dividend growth or issue additional shares, which could dilute existing shareholder value.
• Integration Success: The 5–7% growth target relies on two key factors: the seamless integration of computer and operational systems, and sustained housing growth in the Nashville area. If the integration hits technical snags or the local housing market cools, the company may struggle to meet its growth projections.
• Earnings Calls: Keep an eye on the Q2 2026 earnings call. This will be the first major opportunity for management to provide concrete data on how these new assets are impacting the bottom line.

6. Who is affected?

• Customers: Service is expected to remain seamless, and Spire has indicated that current service rates will be maintained for the time being.
• Employees: Spire is onboarding 200 former Piedmont employees and has allocated $15 million to hire an additional 50 technical and field staff to support the expansion.

Investor Takeaway: This deal is a clear play for growth in a booming market, but it comes with the trade-off of higher debt. The best way to track the success of this move is to watch the company’s debt-to-capital ratio and listen for updates on integration progress during upcoming earnings calls.
