This Form 8-K, dated November 25, 2024, reports a regulatory filing by Spire Missouri Inc., a wholly owned subsidiary of Spire Inc. (NYSE: SR). The filing concerns a general rate case submitted to the Missouri Public Service Commission (MoPSC) to propose new rates for natural gas distribution services.
Key Financial Metrics and Rate Proposal

- Rate Base Growth: 32% increase compared to the last general rate filing test year ended September 30, 2022.
- Capital Structure Assumptions: 55.0% common equity ratio and 10.5% return on equity.
Material Changes Versus Prior Period
The primary material change is the 32% expansion in the rate base since the 2022 test year, driven by significant infrastructure upgrades and system investments. The filing also proposes updates to recovery mechanisms to address weather and conservation impacts, a revision of the cost of capital, and tariff alignment across service areas.
Outlook, Risks, and Management Commentary
Management anticipates that key measures, including rate base, capital structure, and operating costs, may be updated during the regulatory proceeding. The filing is subject to an 11-month review period by the MoPSC under Missouri law. The proposed rates aim to recover system investments and operating costs necessary for safety, reliability, and customer service enhancements.
