• Robust 10-year capital expenditure forecast of $11.2 billion (FY26-FY35E) supports infrastructure investment and growth.

Risks

• The acquisition of Piedmont Natural Gas Tennessee is expressly conditioned upon closing and requires Tennessee Public Utility Commission approval, with no assurances it will be consummated.
• The offering of the Senior Notes may not be completed, or, if completed, may not be on the terms or within the timeframe currently contemplated.
• Forward-looking statements are subject to various uncertainties and risk factors that may cause future performance or results to differ from those anticipated, as detailed in SEC filings (Form 10-K, 10-Q).
• The evaluation process for the sale of gas storage facilities is ongoing, and any sale requires final authorization by Spire's Board of Directors, with no guarantee of completion or terms.

Future Outlook

Spire projects a long-term adjusted EPS growth target of 5-7%, supported by robust rate base growth of approximately 7% in Missouri and 7.5% in Tennessee, and regulated equity growth of about 6% in Alabama and Gulf. The company provided FY26 adjusted EPS guidance of $5.25 to $5.45 and FY27 adjusted EPS guidance of $5.65 to $5.85, with the latter reflecting a full year of earnings from the Piedmont Tennessee acquisition and excluding earnings from expected storage asset sales. A 10-year capital expenditure plan of $11.2 billion (FY26-FY35E) underscores significant infrastructure investment. The dividend growth is expected to be supported by the adjusted earnings per share growth.

Industry Context

The natural gas utility sector continues to focus on infrastructure modernization, safety, and reliability, while balancing customer affordability. Spire's strategy aligns with these trends through its robust capital expenditure plan and focus on constructive regulatory mechanisms. The company highlights natural gas as an affordable choice, noting electricity is 2x to 3x more expensive in its operating states and that natural gas bills represent a minimal portion of household income, positioning it favorably against electrification trends.

Comparison to Industry Standards

• Electricity is 2x to 3x more expensive than natural gas in Spire's operating states (Missouri, Alabama, Mississippi), based on US Energy Information Agency residential customer electric rates for the twelve-month average ending August 2025.
• Natural gas bills represent a minimal portion of wallet share for both low-income (1.32%-1.85%) and median-income (1.06%-1.48%) households in Spire's service territories.
• Spire's regulatory jurisdictions are assessed with RRA rankings of 'Above Average' for Alabama (1), Mississippi (3), and Tennessee (3), and 'Average' for Missouri (2), indicating a generally favorable regulatory environment compared to other jurisdictions.

Stakeholder Impact

• Shareholders: Potential for increased long-term EPS growth (5-7% target), continued dividend increases (23 consecutive years), and enhanced scale and diversification from the acquisition.
• Customers: Improved safety and reliability through robust infrastructure investment ($11.2B capex), focus on cost management and affordability, and expansion of natural gas services into new territories.
• Employees: Integration of Piedmont Natural Gas Tennessee business will likely involve new employees joining Spire, requiring seamless integration efforts.
• Creditors: Issuance of Senior Notes and Junior Subordinated Notes impacts the company's debt structure, with a target FFO/Debt ratio of 15-16% to maintain balance sheet strength.

Next Steps

• Close the acquisition of Piedmont Natural Gas Tennessee business in Q1 calendar 2026, pending Tennessee Public Utility Commission approval.
• Conclude the evaluation and potential sale of gas storage assets, subject to Board of Directors authorization.
• Integrate the acquired Piedmont Tennessee business seamlessly.
• File a future test year rate case in Missouri, leveraging the new legislative allowance (SB 4) effective July 2026.
