Item 7.01 Regulation FD Disclosure.

As previously disclosed, during the second quarter of fiscal 2026, management of Spire Inc. (the “Company”) determined that as a result of recent dispositions, the operations of Spire Marketing Inc. (“Spire Marketing”) and Spire Storage met the criteria for presentation as discontinued operations under Accounting Standards Codification Topic 205-20, Presentation of Financial Statements—Discontinued Operations (“ASC 205-20”). In addition, the Company revised its reportable segments, and results of Spire MoGas and Spire STL Pipeline, previously reflected in the Midstream segment, are now included in Other.

In accordance with ASC 205-20, the Company has recast its previously reported fiscal year 2025 quarterly financial information to present the results of Spire Marketing and Spire Storage as discontinued operations for all periods presented and to reflect a change in segment reporting. This reclassification is presentational only. Consolidated net income, total assets, stockholders’ equity, and cash flows as previously reported for each period are unchanged. This Current Report and the Exhibit attached hereto are not an amendment to, or a restatement of, the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025, nor do they revise any other information contained in that report.

An investor presentation containing the unaudited recast quarterly financial information is included in Exhibit 99.1 attached to this Current Report on Form 8-K and has been made available on the Investor Relations section of its website at https://investors.spireenergy.com.

The information contained in this Item 7.01, including Exhibit 99.1, is being furnished pursuant to Regulation FD and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor otherwise subject to the liabilities of that section, and shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
