Ladies and Gentlemen:

Spire Inc., a Missouri corporation (the "<u>Company</u>"), confirms its agreement with BMO Capital Markets Corp. ("<u>BMO</u>"), J.P. Morgan Securities LLC ("<u>JPM</u>"), Mizuho Securities USA LLC ("<u>Mizuho</u>") and U.S. Bancorp Investments, Inc. ("<u>USB</u>") and each of the other Underwriters named in Exhibit A hereto (collectively, the "<u>Underwriters</u>," which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom BMO, JPM, Mizuho and USB are acting as representatives (each of BMO, JPM, Mizuho and USB, in such capacity, a "<u>Representative</u>" and, collectively, the "<u>Representatives</u>"), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts set forth in Exhibit A hereto of $400,000,000 aggregate principal amount of the Company's 4.600% Senior Notes due 2031 (the "<u>Securities</u>"). Certain terms used in this Underwriting Agreement (this "<u>Agreement</u>") are defined in Section 15 hereof.

The Securities are to be issued pursuant to the Indenture (For Unsecured Debt Securities), dated as of August 19, 2014, between the Company and Regions Bank (as successor in interest to UMB Bank & Trust, N.A.), as trustee (the "<u>Trustee</u>"), as previously amended or supplemented prior to the Closing Date (as defined in Section 2(b) hereof) (as so amended or supplemented, the "<u>Base Indenture</u>"), and as to be further amended or supplemented by the Fourth Supplemental Indenture thereto, dated as of the Closing Date, between the Company and the Trustee (the "<u>Supplemental Indenture</u>" and the Base Indenture, as amended or supplemented by the Supplemental Indenture, the "<u>Indenture</u>").

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

------

The Company has prepared and previously delivered to you a preliminary prospectus supplement dated February 4, 2026 relating to the Securities and a related prospectus dated May 7, 2025 (the "<u>Base Prospectus</u>"). Such preliminary prospectus supplement and the Base Prospectus, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are hereinafter called, collectively, the "<u>Pre-Pricing Prospectus</u>." Promptly after the execution and delivery of this Agreement, the Company will prepare and file with the Commission a prospectus supplement dated February 4, 2026 (the "<u>Prospectus Supplement</u>") and will file the Prospectus Supplement and the Base Prospectus with the Commission, all in accordance with the provisions of Rule 430B and Rule 424(b), and the Company has previously advised you of all information (financial and other) that will be set forth therein. The Prospectus Supplement and the Base Prospectus, in the form first furnished to the Underwriters for use in connection with the offering of the Securities (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are herein called, collectively, the "<u>Prospectus</u>."

SECTION 1. <u>Representations and Warranties.</u><u> </u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) <u>Status as a Well-Known Seasoned Issuer</u>. At (A) the respective times the Registration Statement or any amendments thereto were filed with the Commission, (B) the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was any post-effective amendment thereto, any report filed pursuant to Section 13 or 15(d) of the 1934 Act and incorporated by reference therein or any form of prospectus), (C) any time the Company or any person acting on its behalf (within the meaning, for this clause (1) only, of paragraph (c) of Rule 163) made any offer relating to the Securities in reliance on the exemption of Rule 163 and (D) the date hereof, the Company was and is a "well-known seasoned issuer" (as defined in Rule 405), including not having been and not being an "ineligible issuer" (as defined in Rule 405, without taking into account any determination made by the Commission pursuant to paragraph (2) of the definition of such term in Rule 405); and without limitation to the foregoing, the Company has at all relevant times met, meets and will at all relevant times meet the requirements of Rule 164 for the use of a free writing prospectus (as defined in Rule 405) in connection with the offering contemplated hereby. The Registration Statement is an "automatic shelf registration statement" (as defined in Rule 405), and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on such "automatic shelf registration statement." The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of the automatic shelf registration statement form. Any written communication that was an offer relating to the Securities made by the Company or any person acting on its behalf (within the meaning, for this sentence only, of paragraph (c) of Rule 163) prior to the filing of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including the legending requirement, to qualify such offer for the exemption from Section 5(c) of the 1933 Act provided by Rule 163.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Settlement Without Consent if Failure to Reimburse</u>. If at any time an Indemnified Party shall have requested an indemnifying party to reimburse such Indemnified Party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by clause (B) of Section 6(a) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such Indemnified Party in accordance with such request prior to the date of such settlement.

If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an Indemnified Party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, liabilities, claims, damages and expenses incurred by such Indemnified Party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an Indemnified Party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in investigating, preparing for or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

------

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each affiliate of any Underwriter, each officer, director, employee, partner and member of any Underwriter or any such affiliate, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. Each Underwriter's obligation to contribute pursuant to this Section 7 are several in proportion to the principal amount of Securities set forth opposite its name in Exhibit A hereto and not joint.

SECTION 8. <u>Representations, Warranties and Agreements to Survive Delivery</u>. All representations, warranties and agreements contained in this Agreement or in certificates signed by any officer of the Company or any of its subsidiaries (whether signed on behalf of such officer, the Company or such subsidiary) and delivered to the Representatives or counsel for the Underwriters shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any officer, director, employee, partner, member or agent of any Underwriter or any person or entity controlling any Underwriter or by or on behalf of the Company, any officer, director or employee of the Company or any person or entity controlling the Company and shall survive delivery of and payment for the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

The issuer has filed a registration statement (including a base prospectus) and the Preliminary Prospectus Supplement (including such base prospectus) with the SEC for the offering of the Notes to which this communication relates (File No. 333-287024). Before you invest, you should read the Preliminary Prospectus Supplement (including such base prospectus) and any other documents the issuer has filed with the SEC for more complete information about the issuer and the offering of the Notes. You may get these documents for free by searching the SEC online database (EDGAR) on the SEC website at http://www.sec.gov. Alternatively, the issuer, any underwriter or any dealer participating in the offering of the Notes will arrange to send you the Preliminary Prospectus Supplement (including such base prospectus) if you request it by calling BMO Capital Markets Corp. toll-free at 1-888-200-0266, J.P. Morgan Securities LLC collect at 1-212-834-4533, Mizuho Securities USA LLC toll-free at 1-866-271-7403 or U.S. Bancorp Investments, Inc. toll-free at 1-877-558-2607.

This communication should be read in conjunction with the Preliminary Prospectus Supplement (including such base prospectus). The information in this communication supersedes the information in the Preliminary Prospectus Supplement (including such base prospectus) to the extent inconsistent with the information therein.

\* A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

\*\* It is expected that delivery of the Notes will be made against payment for the Notes on or about February 9, 2026, which is the third business day following the date of this pricing term sheet (such settlement cycle being referred to as "T+3"). Under Rule 15(c)6-1 under the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to the first business day before delivery will be required, by virtue of the fact that the Notes initially will settle in T+3, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the Notes who wish to trade the Notes on any date prior to the first business day before delivery should consult their own advisors.

Re: Underwriting Agreement

Ladies and Gentlemen:

We have acted as special counsel for Spire Inc., a Missouri corporation (the "<u>Company</u>"), in connection with the issuance and sale by the Company, pursuant to the Underwriting Agreement, dated February 4, 2026 (the "<u>Underwriting Agreement</u>"), between the Company and the several underwriters listed on Exhibit A thereto (collectively, the "<u>Underwriters</u>"), for whom BMO Capital Markets Corp., J.P. Morgan Securities LLC, Mizuho Securities USA LLC and U.S. Bancorp Investments, Inc. are acting as representatives, of $400,000,000 aggregate principal amount of the Company's 4.600% Senior Notes due 2031 (the "<u>Securities</u>"). The Securities are to be issued pursuant to the Indenture (For Unsecured Debt Securities), dated as of August 19, 2014, between the Company and Regions Bank (as successor in interest to UMB Bank & Trust, N.A.), as trustee (the "<u>Trustee</u>"), as previously amended or supplemented prior to the date hereof (as so amended or supplemented, the "<u>Base Indenture</u>"), and as to be further amended or supplemented by the Fourth Supplemental Indenture thereto, dated as of the date hereof, between the Company and the Trustee (the "<u>Supplemental Indenture</u>" and the Base Indenture, as amended or supplemented by the Supplemental Indenture, the <u>"Indenture</u>").

This letter is delivered to you at the request of the Company pursuant to Section 5(b) of the Underwriting Agreement. All capitalized terms used in this letter, without definition, have the meanings assigned to them in the Underwriting Agreement.

In reaching the conclusions expressed herein, and acting in our capacity as counsel for the Company in connection with the above-referenced transactions, we have examined originals, or copies certified or otherwise identified to our satisfaction, of each of the following documents (collectively, the "<u>Examined Documents</u>"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Underwriting Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) the form of Securities included in the Supplemental Indenture;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the registration statement on Form S-3 (File No.: 333-287024) of the Company filed on May 7, 2025 with the Securities and Exchange Commission (the "<u>Commission</u>") (such registration statement, including the documents incorporated therein by reference, the "<u>Registration Statement</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) the prospectus dated May 7, 2025 (together with the documents incorporated therein by reference, the "<u>Base Prospectus</u>") included in the Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the preliminary prospectus supplement dated February 4, 2026 (such preliminary prospectus supplement, together with the Base Prospectus, the "<u>Pre-Pricing Prospectus</u>" and, together with the pricing term sheet set forth on Exhibit C to the Underwriting Agreement, the "<u>General Disclosure Package</u>"), filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the final prospectus supplement dated February 4, 2026 (the "<u>Prospectus Supplement</u>" and, together with the Base Prospectus, the "<u>Prospectus</u>"), filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act.

The documents referenced in clauses (a), (b) and (c) above are collectively referred to herein as the "<u>Transaction Documents</u>."

In addition, we have examined the following documents (collectively, the "<u>Due Diligence Documents</u>"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Officer's Certificate of the Company, a copy of which is attached hereto as <u>Exhibit A</u> (the "<u>Officer's Certificate</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the various certificates and other closing documents delivered in connection with the closing of the transactions contemplated by the Underwriting Agreement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) such other documents, agreements and instruments as we have deemed necessary or appropriate as a basis for the opinions hereafter expressed.

We have examined originals or certified copies of such corporate records of the Company and other certificates and documents of officials of the Company, public officials and others as we have deemed appropriate for purposes of this letter, and relied upon them to the extent we deem appropriate, except where a statement is qualified as to knowledge or awareness, in which case we have made limited inquiry, as specified below. As to various questions of fact relevant to the opinions in this letter, we have relied, without independent investigation, upon the Due Diligence Documents, certificates of public officials, certificates of officers of the Company, and representations and warranties of the Company contained in the Underwriting Agreement and the Due Diligence Documents and of the Underwriters contained in the Underwriting Agreement, all of which we assume to be true, correct and complete. In addition, we have made no inquiry of the Company or any other person or entity (including governmental authorities) regarding, and no review of, any judgments, orders, decrees, franchises, licenses, certificates, permits or other public records or agreements to which the Company is a party other than the Examined Documents and the Due Diligence Documents, and our knowledge of any such matters is accordingly limited.

------

We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to authentic original documents of all copies submitted to us as conformed, certified or reproduced copies and the conformity of the Securities to the forms thereof that we have reviewed. In our examination of documents, we have also assumed (a) the due organization, valid existence and good standing under the Laws (as defined below) of its jurisdiction of organization of each party to the Transaction Documents, (b) the legal capacity of natural persons, (c) the corporate or other power and due authorization of each of the Company and the other parties signatory thereto to execute, deliver and perform its obligations under the Transaction Documents, and to consummate the transactions contemplated therein, (d) the due execution and delivery of the Transaction Documents by all parties thereto (other than, in the case of each Transaction Document, the Company) and (e) that each of the Transaction Documents constitutes a valid and binding agreement or obligation of each party thereto, enforceable against such party in accordance with its terms (other than, in the case of the Company, the Transaction Documents referred to in paragraphs 2 and 3 below).

Based upon the foregoing and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Underwriting Agreement has been duly executed and delivered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Each of the Base Indenture and the Supplemental Indenture has been duly executed and delivered by the Company and constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its terms; and the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Upon (a) the due execution of the Securities by the Company, (b) the due authentication of the Securities by the Trustee pursuant to the Indenture and (c) the delivery of the Securities against payment therefor in accordance with the Underwriting Agreement, the Securities will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, and will be entitled to the benefits provided by the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The Registration Statement originally became automatically effective under the Securities Act upon filing on May 7, 2025; the Pre-Pricing Prospectus and the Prospectus and any amendments or supplements thereto have been filed with the Commission pursuant to Rule 424(b) under the Securities Act; and, to our knowledge, no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose is pending or threatened by the Commission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. The statements in the General Disclosure Package and the Prospectus under the captions "Description of the Notes" and "Description of Debt Securities," insofar as they purport to constitute summaries of certain terms of the documents referred to therein, constitute accurate summaries of such terms of such documents in all material respects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. The statements in the General Disclosure Package and the Prospectus under the caption "Material United States Federal Income Tax Consequences," insofar as such statements purport to summarize the U.S. federal tax Laws or legal conclusions with respect thereto, are correct in all material respects.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. The Securities will be treated as indebtedness for U.S. federal income tax purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency under any Included Law (other than under the Securities Act or the Securities Exchange Act of 1934, as amended, or in each case the General Rules and Regulations thereunder, which have been made or obtained, or as may be required under state securities or blue sky Laws, as to which we express no opinion), is necessary or required for the authorization, execution or delivery of the Transaction Documents by the Company or for the issuance and sale of the Securities by the Company pursuant to the Transaction Documents.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. The execution and delivery by the Company of the Transaction Documents and the performance by the Company of its obligations thereunder will not violate or result in a default by the Company under (a) any Included Law or (b) to our knowledge, any order of any governmental authority or regulatory body having jurisdiction over the Company or any of its properties under any Included Law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. The Company is not, and immediately after the closing of the transactions contemplated by the Underwriting Agreement and the application of the proceeds thereof as described in the General Disclosure Package and the Prospectus, the Company will not be, an "investment company" required to register under the Investment Company Act of 1940, as amended.

The opinions, negative assurance and other matters in this letter are qualified in their entirety and subject to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. We express no opinion as to the laws of any jurisdiction other than the Included Laws. We have made no special investigation or review of any published constitutions, treaties, laws, rules or regulations or judicial or administrative decisions ("<u>Laws</u>"), other than a review of (i) the Laws of the State of New York and (ii) the federal laws of the United States of America. For purposes of this letter, the term "<u>Included Laws</u>" means the items described in clauses (i) and (ii) of the preceding sentence that are, in our experience, normally applicable to transactions of the type contemplated in the Underwriting Agreement. The term Included Laws specifically excludes (a) Laws of any counties, cities, towns, municipalities and special political subdivisions and any agencies thereof, (b) zoning, land use, building and construction Laws, (c) Federal Reserve Board margin regulations, (d) any environmental, labor, tax (other than as provided in paragraphs 6 and 7 above), pension, employee benefit, antiterrorism, money laundering, foreign investment, insurance, commodity, antitrust, intellectual property and state securities or "blue sky" Laws and (e) any Laws that may be applicable to the Company and its subsidiaries by virtue of the particular nature of the businesses conducted by them or any goods or services provided by them or property owned or leased by them.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. When used in the opinions in this letter, the phrase ****"to our knowledge" and similar phrases (i) mean, as of the date hereof, the conscious awareness of facts or other information by any lawyer in our firm actively involved in negotiating and preparing the Examined Documents and any lawyer in our firm who otherwise devotes substantive attention to matters of the Company on behalf of this firm and could reasonably be expected to have information material to the opinions expressed herein and (ii) do not require or imply (a) any examination of any other person's or entity's files, (b) that any inquiry be made of the client (other than as to the existence of any order referred to in paragraph 9(b) above), any lawyer (other than the lawyers described above), or any other person or entity or (c) any review or examination of any agreements, documents, certificates, instruments or other papers other than the Underwriting Agreement or the other Examined Documents, the Due Diligence Documents and the corporate records referred to in the fifth paragraph of this letter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. This letter and the matters addressed herein are as of the date hereof or such earlier date as is specified herein, and we undertake no, and hereby disclaim any, obligation to advise you or any other person or entity of any change in any matter set forth herein, whether based on a change in the Law, a change in any fact relating to the Company or any other person or entity, or any other circumstance. This letter is limited to the matters expressly stated herein and no opinions are to be inferred or may be implied beyond the opinions expressly set forth herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. The matters expressed in paragraphs 2 and 3 of this letter are subject to and qualified and limited by (i) applicable bankruptcy, insolvency, fraudulent transfer and conveyance, reorganization, moratorium and similar Laws affecting creditors' rights and remedies generally, (ii) general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief (regardless of whether considered in a proceeding in equity or at law), (iii) Laws and public policy with respect to rights to indemnification or contribution, (iv) constitutional bounds on Laws that govern the enforceability of choice of law provisions in agreements and (v) the effect of Laws other than the Included Laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. With respect to the opinion expressed in paragraph 4 above (a) as to the automatic effectiveness of the Registration Statement, we have assumed the Company has not failed to file any reports required for the Company to constitute a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act and (b) as to the absence of stop orders suspending the effectiveness of the Registration Statement or the initiation or threat of any proceedings thereto, we have relied, without any further inquiry, solely on our review of the information posted prior to [__:__] a.m., New York City time, on the date of this letter on the Commission's website at <u>https://www.sec.gov/litigation/stoporders.shtml.</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. The opinion expressed in paragraph 7 above is based on current provisions of the Internal Revenue Code of 1986, as amended, treasury regulations promulgated thereunder, judicial decisions, published positions of the Internal Revenue Service, and such other authorities as we have considered relevant for such opinion, all as of the date of this opinion and all of which are subject to change or differing interpretations, possibly with retroactive effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. We express no opinion with respect to the fairness of the Transaction Documents or any other matter, and in rendering the opinions expressed herein, we have assumed, with your consent, that a court of competent jurisdiction would find all such matters were entirely fair. We assume that no fraud, dishonesty, forgery, coercion, duress or breach of fiduciary duty exists or will exist with respect to any of the matters relevant to the opinions expressed herein.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. We have assumed that the application of the proceeds from the offering of the Securities is as described in the General Disclosure Package.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. We express no opinion as to (i) the compliance of the transactions contemplated by the Transaction Documents with any regulations or governmental requirements applicable to any party other than the Company, (ii) the financial condition or solvency of the Company or the Company's compliance with any financial covenant or similar economic requirement or condition, (iii) the ability (financial or otherwise) of the Company or any other party to meet their respective obligations under the Transaction Documents, (iv) the compliance of the Transaction Documents or the transactions contemplated thereby with, or the effect on any of the opinions expressed herein of, the antifraud provisions of federal and state securities Laws, rules and regulations or (v) the conformity of the Transaction Documents to any term sheet or commitment letter.

\* \* \*

For purposes of this letter, we have assumed the information in the Prospectus Supplement of the type referred to in Rule 430B(f)(1) of the General Rules and Regulations under the Securities Act was deemed to be a part of and included in the Registration Statement pursuant to such Rule 430B(f)(1) as of the date of the Underwriting Agreement. Our identification of documents and information as part of the General Disclosure Package has been at your request and with your approval. Such identification is for the limited purpose of making the statements set forth in this letter and is not the expression of a view by us as to whether any such information has been or should have been conveyed to investors generally or to any particular investors at any particular time or in any particular manner.

Because the primary purpose of our professional engagement was not to establish or confirm factual matters or financial, accounting or statistical information, and we have not participated in the preparation of the documents incorporated by reference in the Registration Statement, the General Disclosure Package, or the Prospectus and because many determinations involved in the preparation of the Registration Statement, the General Disclosure Package, and the Prospectus are of a wholly or partially non-legal character, except as expressly set forth in paragraphs 5 and 6 of this letter, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements.

However, in the course of our acting as counsel for the Company in connection with the preparation of the Registration Statement, the General Disclosure Package and the Prospectus, we have reviewed each such document and have participated in conferences and telephone conversations with representatives of and other counsel for the Company, representatives of the independent public accountants for the Company, representatives of the Underwriters and representatives of the Underwriters' counsel, during which conferences and conversations the contents of such documents and related matters were discussed.

------

Subject to the foregoing, we confirm to you that, on the basis of the information we gained in the course of performing the services referred to above:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each of the Registration Statement, as of the date of the Underwriting Agreement, and the Prospectus, as of the date of the Prospectus Supplement, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations thereunder, except that (i) we express no view as to the financial statements, financial schedules and other financial and accounting data (and statistical data derived therefrom) contained or incorporated by reference therein or omitted therefrom and (ii) we express no view as to the antifraud provisions of the United States federal securities Laws and the rules and regulations promulgated under such provisions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) No facts have come to our attention that cause us to believe that (i) the Registration Statement, as of the date of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the General Disclosure Package, considered together as of 3:15 p.m. on February 4, 2026 (which you have informed us is a time prior to the time of the first sale of the Securities by any Underwriter), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, as of the date of the Prospectus Supplement or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i) through (iii) above, we do not express any view as to the financial statements, financial schedules and other financial and accounting data (and statistical data derived therefrom) contained or incorporated by reference therein or omitted therefrom.

This letter is solely for your benefit and the benefit of the other Underwriters and no other person or entity shall be entitled to rely upon this letter. Without our prior written consent, this letter may not be quoted in whole or in part or otherwise referred to in any document and may not be furnished or otherwise disclosed to or used by any other person or entity, except for (i) delivery of copies hereof to counsel for any of the Underwriters, (ii) inclusion of copies hereof in a closing file and (iii) use hereof in any legal proceeding arising out of the transactions contemplated by the Underwriting Agreement or the other Transaction Documents filed by an addressee hereof against this law firm or in which any addressee hereof is a defendant.

Re: Underwriting Agreement

Ladies and Gentlemen:

I am Senior Vice President and Chief Legal Officer of Spire Inc., a Missouri corporation (the "<u>Company</u>"). In such capacity, I have represented the Company in connection with the issuance and sale by the Company, pursuant to the Underwriting Agreement, dated February 4, 2026 (the "<u>Underwriting Agreement</u>"), between the Company and the several underwriters listed on Exhibit A thereto (collectively, the "<u>Underwriters</u>"), for whom BMO Capital Markets Corp., J.P. Morgan Securities LLC, Mizuho Securities USA LLC and U.S. Bancorp Investments, Inc. are acting as representatives, of $400,000,000 aggregate principal amount of the Company's 4.600% Senior Notes due 2031 (the "<u>Securities</u>"). The Securities are to be issued pursuant to the Indenture (For Unsecured Debt Securities), dated as of August 19, 2014, between the Company and Regions Bank (as successor in interest to UMB Bank & Trust, N.A.), as trustee (the "<u>Trustee</u>"), as previously amended or supplemented prior to the date hereof (as so amended or supplemented, the "<u>Base Indenture</u>"), and as to be further amended or supplemented by the Fourth Supplemental Indenture thereto, dated as of the date hereof, between the Company and the Trustee (the "<u>Supplemental Indenture</u>" and the Base Indenture, as amended or supplemented by the Supplemental Indenture, the "<u>Indenture</u>"). This letter is delivered to you at the request of the Company pursuant to Section 5(b) of the Underwriting Agreement.

As such counsel, I have examined:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Articles of Incorporation and all amendments thereto of the Company (the "<u>Articles</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the Bylaws and all amendments thereto of the Company (the "<u>Bylaws</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) all relevant corporate proceedings of the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) the Underwriting Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) the Indenture;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the forms of the Securities included in the Supplemental Indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the registration statement on Form S-3 (File No.: 333-287024) of the Company filed on May 7, 2025 with the Securities and Exchange Commission (the "<u>Commission</u>") (such registration statement, including the documents incorporated therein by reference, the "<u>Registration Statement</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) the prospectus dated May 7, 2025 (together with the documents incorporated therein by reference, the "<u>Base Prospectus</u>") included in the Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the preliminary prospectus supplement dated February 4, 2026 (such preliminary prospectus supplement, together with the Base Prospectus, the "<u>Pre-Pricing Prospectus</u>" and, together with the pricing term sheet set forth on Exhibit C to the Underwriting Agreement, being referred to herein as the "<u>General Disclosure Package</u>"), filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act of 1933, as amended (the "<u>Securities Act</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) the final prospectus supplement dated February 4, 2026 (the "<u>Prospectus Supplement</u>" and, together with the Base Prospectus, the "<u>Prospectus</u>"), filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act; and

The documents referenced in (d), (e) and (f) above are collectively referred to herein as the "<u>Transaction Documents</u>."

I have also examined (a) originals, or copies certified or otherwise identified to my satisfaction, of such agreements, documents, certificates, corporate and official records, affidavits and other instruments and (b) such laws, rules and regulations as I deemed necessary or appropriate for purposes of this letter. In such examinations, I have assumed (without independent investigation, verification or inquiry) the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to me as originals and the conformity with the originals of all documents submitted to me as copies. As to various questions of fact relevant to the opinions in this letter, I have relied, without independent investigation, upon certificates of public officials, certificates of officers of the Company and representations and warranties of the Company contained in the Underwriting Agreement. For purposes of this letter, "<u>Principal Subsidiary</u>" shall mean each of Spire Alabama Inc., an Alabama corporation, Spire Missouri Inc., a Missouri corporation ("<u>Spire Missouri</u>"), and Spire Midstream LLC, a Missouri limited liability company ("<u>Spire Midstream</u>").

Based upon such review and upon such inquiries and investigations of the Company as I deemed necessary or relevant, I am of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Missouri.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and to enter into and perform its obligations under the Underwriting Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. The Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. (i) Spire Missouri has been duly organized and is validly existing as a corporation in good standing under the laws of Missouri, (ii) Spire Midstream has been duly organized and is validly existing as a limited liability company in good standing under the laws of Missouri, (iii) Spire Missouri has power and authority as a corporation to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus, (iv) Spire Midstream has power and authority as a limited liability company to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and (v) each Principal Subsidiary is duly qualified as a foreign corporation or limited liability company, as applicable, to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not, individually or in the aggregate, result in a Material Adverse Effect; and except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, all of the issued and outstanding shares of capital stock or membership interests, as applicable, of each Principal Subsidiary are, to my knowledge, owned by the Company, directly or through subsidiaries, free and clear of any Lien, all the shares of capital stock of Spire Missouri have been duly authorized and validly issued and are fully paid and non-assessable and all the membership interests of Spire Midstream have been duly authorized and validly issued and are fully paid and non-assessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. Each of the Base Indenture and the Supplemental Indenture has been duly authorized, executed and delivered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. The Securities have been duly authorized, executed and delivered by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. To the best of my knowledge, except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending or threatened, against or affecting the Company or any of its subsidiaries that is required to be disclosed in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, or that would reasonably be expected to result in a Material Adverse Effect or to materially and adversely affect the consummation of the transactions contemplated in the Underwriting Agreement or the performance by the Company of its obligations thereunder.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. The information in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2025, under the captions "Legal Proceedings," "Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates—Regulatory Accounting" and "Management's Discussion and Analysis of Financial Condition and Results of Operations—Regulatory Matters," and in Item 13 thereof under the caption "Certain Relationships and Related Transactions, and Director Independence," in each case to the extent that it constitutes matters of law, summaries of legal matters, summaries of provisions of the Articles or Bylaws or any other material agreement, summaries of legal proceedings, or legal conclusions, is accurate in all material respects, except as such information has been supplemented or superseded by information contained in any periodic or current report under the Securities Exchange Act of 1934, as amended, filed by the Company with the Commission after September 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. (A) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency of the State of Missouri (other than as may be required under state securities or blue sky laws, as to which I express no opinion), and (B) no authorization, approval, vote or other consent of any stockholder of the Company, is necessary or required for the authorization, execution or delivery of the Underwriting Agreement by the Company for the issuance and sale of the Securities pursuant to the Underwriting Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;11. The execution and delivery by the Company of the Transaction Documents and the performance by the Company of its obligations thereunder (including the issuance and sale of the Securities as contemplated therein) will not (a) violate or result in a default under the Articles or Bylaws, (b) violate any applicable law or statute of the State of Missouri or the United States of America known to me to be generally applicable to transactions of this type, (c) violate or result in a default under any order, rule or regulation of any court or governmental authority or agency of the State of Missouri or the United States of America that is binding on the Company or any of its subsidiaries or any of its property or (d) result in a breach of, or default under, any indenture, mortgage, deed of trust or other material agreement or instrument known to me after due inquiry to which the Company or any of its subsidiaries is a party or by which it is bound or to which any of the property of the Company or any of its subsidiaries is subject; except, with respect to clauses (b), (c) and (d) of this paragraph, such violations, breaches or defaults that would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. To my knowledge, there are no franchises, contracts, indentures, mortgages, deeds of trust, loan or credit agreements, bonds, notes, debentures, evidences of indebtedness, leases or other instruments or agreements required to be described or referred to in the Registration Statement, the General Disclosure Package or the Prospectus that have not been so described and filed as required.

------

The opinion expressed in clause (v) of paragraph 4 herein is given solely on the basis of certificates of the State agencies or officials set forth in <u>Schedule A</u>, speaks only as of the dates indicated in such schedule and is limited to the meaning ascribed to such certificates by each applicable State agency and applicable law.

\* \* \*

For purposes of this letter, I have assumed the information in the Prospectus Supplement of the type referred to in Rule 430B(f)(1) of the General Rules and Regulations under the Securities Act was deemed to be a part of and included in the Registration Statement pursuant to such Rule 430B(f)(1) as of the date of the Underwriting Agreement. My identification of documents and information as part of the General Disclosure Package has been at your request and with your approval. Such identification is for the limited purpose of making the statements set forth in this letter and is not the expression of a view by me as to whether any such information has been or should have been conveyed to investors generally or to any particular investors at any particular time or in any particular manner.

Because many determinations involved in the preparation of the Registration Statement, the General Disclosure Package, and the Prospectus are of a wholly or partially non-legal character, except as expressly set forth in paragraph 9 of this letter, I am not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus and I make no representation that I have independently verified the accuracy, completeness or fairness of such statements.

However, in the course of my acting as counsel for the Company in connection with the preparation of the Registration Statement, the General Disclosure Package and the Prospectus, I have reviewed each such document and have participated in conferences and telephone conversations with other representatives of the Company, representatives of the Company's outside counsel, representatives of the independent public accountants for the Company, representatives of the Underwriters and representatives of the Underwriters' counsel, during which conferences and conversations the contents of such documents and related matters were discussed. In passing upon the form of the Registration Statement and the form of the Prospectus, I necessarily assume the correctness and completeness of the statements made by the Company and information included therein and take no responsibility therefor, except insofar as such statements relate to me.

Subject to the foregoing, I confirm to you that, on the basis of the information I gained in the course of performing the services referred to above:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each of the Registration Statement, as of the date of the Underwriting Agreement, and the Prospectus, as of the date of the Prospectus Supplement, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations thereunder, except that (i) I express no view as to the financial statements, financial schedules and other financial and accounting data (and statistical data derived therefrom) contained or incorporated by reference therein or omitted therefrom and (ii) I express no view as to the antifraud provisions of the United States federal securities laws and the rules and regulations promulgated under such provisions; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) No facts have come to my attention that cause me to believe that (i) the Registration Statement, as of the date of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the General Disclosure Package, considered together as of 3:15 p.m. on February 4, 2026 (which you have informed me is a time prior to the time of the first sale of the Securities by any Underwriter), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, as of the date of the Prospectus Supplement or as of the date hereof, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i) through (iii) above, I do not express any view as to the financial statements, financial schedules and other financial and accounting data (and statistical data derived therefrom) contained or incorporated by reference therein or omitted therefrom.

I am a member of the Bar of the State of Missouri and I do not purport to be an expert on, or to express any opinion herein concerning, any matter governed by the laws of any jurisdiction other than the laws of the State of Missouri and the federal laws of the United States of America. Further, I express no opinion with respect to any law, rule, regulation or matter regarding (i) any matters of local law (i.e., laws, rules and regulations of counties, towns, municipalities or special political subdivisions and any agencies thereof), (ii) federal or state antitrust or unfair competition laws or (iii) laws relating to land use, zoning and building code issues, taxes, antifraud, environmental issues, intellectual property and state "blue sky" laws.

This opinion is furnished only to the Underwriters and their respective successors, assigns and participants, and is solely for their benefit in connection with the transactions contemplated by the Underwriting Agreement and related documents, amendments and supplements. This opinion is not to be used or otherwise relied upon by any other party or entity or for any other purpose without my prior written consent, except for (i) delivery of copies hereof to counsel for any of the Underwriters and (ii) inclusion of copies hereof in a closing file. Notwithstanding the foregoing, the Trustee is hereby authorized to rely on this letter as though it were an addressee, subject to the assumptions, reservations, conditions and qualifications contained herein.

This opinion is made as of the date hereof, and I undertake no obligation, and hereby disclaim any obligation, to advise you of any change after the date hereof in any matter set forth herein.

As the several Underwriters

Re: Underwriting Agreement

Ladies and Gentlemen:

We are corporate counsel for Spire Alabama Inc., an Alabama corporation ("<u>Spire Alabama</u>") and a wholly owned subsidiary of Spire Inc., a Missouri corporation (the "<u>Company</u>"). In such capacity, we have represented Spire Alabama in connection with the issuance and sale by the Company, pursuant to the Underwriting Agreement, dated February 4, 2026 (the "<u>Underwriting Agreement</u>"), between the Company and the several underwriters listed on Exhibit A thereto (collectively, the "<u>Underwriters</u>"), for whom BMO Capital Markets Corp., J.P. Morgan Securities LLC, Mizuho Securities USA LLC and U.S. Bancorp Investments, Inc. are acting as representatives, of $400,000,000 aggregate principal amount of the Company's 4.600% Senior Notes due 2031 (the "<u>Securities</u>").

All capitalized terms used and not otherwise defined in this letter shall have the respective meanings ascribed to them in the Underwriting Agreement. This letter is delivered to you at the request of the Company pursuant to Section 5(b) of the Underwriting Agreement.

As corporate counsel, we have examined:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the articles of incorporation and amendments thereto of Spire Alabama;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the bylaws and amendments thereto of Spire Alabama;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) a State of Alabama Department of Revenue Certificate of Compliance, dated [•], 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) a certification from the Alabama Secretary of State, dated [•], 2026, regarding records filed in his office;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) relevant corporate proceedings of Spire Alabama;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) the Board Resolutions of the Company, dated January 29, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) the Underwriting Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) the registration statement on Form S-3 (File No.: 333-287024) of the Company filed on May 7, 2025 with the Securities and Exchange Commission (the "<u>Commission</u>"), as amended, (such registration statement, including the documents incorporated therein by reference, the "<u>Registration Statement</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the prospectus dated May 7, 2025 (together with the documents incorporated therein by reference, the "<u>Base Prospectus</u>") included in the Registration Statement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) the preliminary prospectus supplement dated February 4, 2026 (such preliminary prospectus supplement, together with the Base Prospectus, the "<u>Pre-Pricing Prospectus</u>" and, together with the pricing term sheet set forth on Exhibit C to the Underwriting Agreement, being referred to herein as the "<u>General Disclosure Package</u>"), filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act of 1933, as amended (the "<u>Securities Act</u>"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) the final prospectus supplement dated February 4, 2026 (the "<u>Prospectus Supplement</u>" and, together with the Base Prospectus, the "<u>Prospectus</u>") relating to the Securities, filed with the Commission pursuant to Rule 424(b) of the General Rules and Regulations under the Securities Act.

We have also examined (a) originals, or copies certified or otherwise identified to our satisfaction, of such agreements, documents, certificates, corporate and official records, affidavits and other instruments and (b) such laws, rules and regulations as we deemed necessary or appropriate for purposes of this letter. In our examinations, we have assumed (without independent investigation, verification or inquiry) the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies. As to various questions of fact relevant to this letter, we have relied, without independent investigation, upon certificates of public officials, certificates of officers of Spire Alabama and representations and warranties of the Company contained in the Underwriting Agreement and documents filed with the Commission.

Based upon such review and upon such inquiries and investigations of Spire Alabama as we deemed necessary or relevant, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Spire Alabama (a) is a corporation duly organized, validly existing and in good standing under the laws of the State of Alabama and (b) is duly qualified as a foreign corporation and is in good standing in all of the states where the nature of its business or ownership or use of property requires such qualification, except where the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect as defined in the Underwriting Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Spire Alabama has full corporate right, power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, all of the issued and outstanding shares of capital stock of Spire Alabama have been, to our knowledge, duly authorized and validly issued and are fully paid and non-assessable.

The opinions set forth in this letter are qualified in their entirety and subject to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) This opinion is made as of the date hereof, and we undertake no obligation, and hereby disclaim any obligation, to advise you of any change after the date hereof in any matter set forth herein. We are qualified to practice law in the State of Alabama and do not purport to be experts on, or to express any opinion herein concerning, any other published constitutions, treaties, laws, rules or regulations or judicial or administrative decisions ("<u>Requirements of Law</u>") of any jurisdiction other than the Requirements of Law of the State of Alabama. Further, we express no opinion with respect to any Requirement of Law or matter regarding (i) local Requirements of Law (i.e., Requirements of Law of counties, towns, municipalities or special political subdivisions of any agencies thereof), (ii) Federal or state antitrust or unfair competition Requirements of Law or (iii) Requirements of Law relating to land use, zoning and building code issues, taxes, antifraud, environmental issues, intellectual property and state "blue sky" laws. This opinion is limited to the matters expressly stated herein and no opinions are to be inferred or may be implied beyond the opinions expressly stated set forth herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) We have assumed that no fraud, dishonesty, forgery, coercion, duress, or breach of fiduciary duty exists with respect to any of the matters relevant to the opinions expressed in this letter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) We express no opinion as to: (i) compliance of the transactions contemplated by the Underwriting Agreement with any Requirements of Law applicable to any person other than Spire Alabama, (ii) the financial condition or solvency of Spire Alabama, (iii) the ability (financial or otherwise) of the Company or any other Person to meet its obligations under the Underwriting Agreement or (iv) any provision of the Underwriting Agreement that would, to the extent not permitted by applicable Requirements of Law, restrict, waive access to or vary legal or equitable remedies or defenses (including, but not limited to, a right to notice of and hearing on matters relating to prejudgment remedies, service of process, proper jurisdiction and venue, forum non conveniens and the right to trial by jury) or the right to collect damages (including, but not limited to, actual, consequential, special, indirect, incidental, exemplary, and punitive damages).

This opinion is furnished only to the Underwriters and their respective successors, assigns and participants, and is solely for their benefit in connection with the transactions contemplated by the Underwriting Agreement and related documents, amendments and supplements. This opinion is not to be used or otherwise relied upon by any other party or entity or for any other purpose without our prior written consent, except for (i) delivery of copies hereof to counsel for the Underwriters and (ii) inclusion of copies hereof in a closing file. Notwithstanding the foregoing, Regions Bank, as trustee, is hereby authorized to rely on this letter as though it were an addressee, subject to the assumptions, reservations, conditions and qualifications contained herein

Any such additional 2031 Notes will have the same ranking, interest rate, Stated Maturity and other terms as the 2031 Notes herein provided for (except for the original issue date, the public offering price and, if applicable, the initial Interest Payment Date).

If any Interest Payment Date falls on a day that is not a Business Day, the required payment on that day will be due on the next succeeding Business Day, and no interest will accrue or be paid on that payment for the period from and after that Interest Payment Date to the date of payment on the next succeeding Business Day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If the Stated Maturity of principal of the 2031 Notes falls on a day that is not a Business Day, the required payment on that day will be due on the next succeeding Business Day, and no interest on that payment will accrue or be paid for the period from and after the Stated Maturity of principal of the 2031 Notes.

**OPTIONAL REDEMPTION; NO SINKING FUND** 

Section 4.01. <u>Optional Redemption by Company</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The 2031 Notes shall be redeemable, at the option of the Company, in whole or in part, at any time and from time to time, (i) prior to the Par Call Date (as defined below), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (x) the sum of (A) the present values of the remaining scheduled payments of principal and interest on the 2031 Notes being redeemed discounted to the Redemption Date (assuming the 2031 Notes being redeemed matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points, less (B) interest accrued to the Redemption Date and (y) 100% of the principal amount of the 2031 Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (ii) on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the 2031 Notes to be redeemed on the Redemption Date plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

------

Notwithstanding the foregoing, (1) interest payable with respect to an Interest Payment Date on any 2031 Note to be redeemed that falls on or before the Redemption Date therefor shall be made to the holder thereof on the record date related to such Interest Payment Date, and (2) if any Redemption Date falls on a day that is not a Business Day, principal, interest and premium, if any, payable on such date will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the Redemption Date and no interest will accrue on the amount so payable for the period from and after the Redemption Date to the next succeeding Business Day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Notice of any redemption of the 2031 Notes shall be given in the manner and otherwise in accordance with the provisions of Section 404 of the Indenture to each Holder of Securities to be redeemed (with a copy to the Trustee), at his or her address appearing in the Security Register, and any such notice, in lieu of stating the applicable Redemption Price, shall state the manner in which such Redemption Price shall be calculated. If the Company has given notice of redemption as provided in the Indenture and funds for the redemption of the 2031 Notes called for redemption have been made available on the Redemption Date referred to in that notice, such 2031 Notes will cease to bear interest on such Redemption Date (unless the Company defaults in the payment of the applicable Redemption Price and accrued and unpaid interest). Any interest accrued to such Redemption Date will be paid as specified in such notice. Once notice of redemption is mailed by the Company, the Securities called for redemption will become due and payable on the applicable Redemption Date at the Redemption Price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The following defined terms used in this <u>Article Four</u> shall, unless the context otherwise requires, have the meanings specified below:

"<u>Par Call Date</u>" means August 1, 2031.

"<u>Treasury Rate</u>" means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("<u>H.15</u>") under the caption "U.S. government securities—Treasury constant maturities—Nominal" (or any successor caption or heading) ("<u>H.15 TCM</u>"). In determining the Treasury Rate, the Company shall select, as applicable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the "<u>Remaining Life</u>");

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life (for purposes of this clause, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date).

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security and rounded to three decimal places.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) At or prior to the time of giving of any notice of redemption to the Holders of any 2031 Notes to be redeemed, the Company shall deliver an Officer's Certificate to the Trustee setting forth the calculation of the Redemption Price or the manner in which the Redemption Price shall be calculated, as relevant, applicable to such redemption. The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon, the applicable Redemption Price as so calculated, or the manner in which such Redemption Price shall be calculated, as relevant, and set forth in such Officer's Certificate.

Section 4.02. <u>No Other Redemption</u>. Except as set forth in Section 4.01 hereof, the 2031 Notes are not redeemable prior to the Stated Maturity of principal of the 2031 Notes.

Section 4.03. <u>No Sinking Fund</u>. The 2031 Notes are not entitled to the benefit of any sinking fund.

**[Reverse of Security]** 

This Security is one of a duly authorized issue of securities of the Company (herein called the "<u>Securities</u>"), issued and to be issued in one or more series under an Indenture, dated as of August 19, 2014 as supplemented by the first supplemental indenture dated as of August 19, 2014, the second supplemental indenture dated as of February 27, 2017, the third supplemental indenture dated as of February 12, 2024, and the fourth supplemental indenture dated as of February 9, 2026 (herein called the "<u>Indenture</u>", which then shall have the meaning assigned to it in such instrument) between the Company and Regions Bank (as successor to UMB Bank & Trust, N.A.), as trustee (herein called the "<u>Trustee</u>", which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to $400,000,000.

The 2031 Notes shall be redeemable, at the option of the Company, in whole or in part, at any time and from time to time, (i) prior to the Par Call Date (as defined below), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of (x) the sum of (A) the present values of the remaining scheduled payments of principal and interest on the 2031 Notes being redeemed discounted to the Redemption Date (assuming the 2031 Notes being redeemed matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 15 basis points, less (B) interest accrued to the Redemption Date and (y) 100% of the principal amount of the 2031 Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (ii) on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the 2031 Notes to be redeemed on the Redemption Date plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

Notwithstanding the foregoing, (1) interest payable with respect to an Interest Payment Date on any 2031 Note to be redeemed that falls on or before the Redemption Date therefor shall be made to the holder thereof on the record date related to such Interest Payment Date and (2) if any Redemption Date falls on a day that is not a Business Day, principal, interest and premium, if any, payable on such date will be paid on the next succeeding Business Day with the same force and effect as if it were paid on the Redemption Date and no interest will accrue on the amount so payable for the period from and after the Redemption Date to the next succeeding Business Day.

Notice of any redemption of the 2031 Notes shall be given in the manner and otherwise in accordance with the provisions of Section 404 of the Indenture to each Holder of Securities to be redeemed (with a copy to the Trustee), at his or her address appearing in the Security Register, and any such notice, in lieu of stating the applicable Redemption Price, shall state the manner in which such Redemption Price shall be calculated. If the Company has given notice of redemption as provided in the Indenture and funds for the redemption of the 2031 Notes called for redemption have been made available on the Redemption Date referred to in that notice, such 2031 Notes will cease to bear interest on such Redemption Date (unless the Company defaults in the payment of the applicable Redemption Price and accrued and unpaid interest). Any interest accrued to such Redemption Date will be paid as specified in such notice.

------

"<u>Par Call Date</u>" means August 1, 2031.

"<u>Treasury Rate</u>" means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as "Selected Interest Rates (Daily)—H.15" (or any successor designation or publication) ("<u>H.15</u>") under the caption "U.S. government securities—Treasury constant maturities—Nominal" (or any successor caption or heading) ("<u>H.15 TCM</u>"). In determining the Treasury Rate, the Company shall select, as applicable:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the "<u>Remaining Life</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life (for purposes of this clause, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date).

If on the third Business Day preceding the Redemption Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date. If there is no United States Treasury security maturing on the Par Call Date, but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security and rounded to three decimal places.

------

At or prior to the time of giving of any notice of redemption to the Holders of any 2031 Notes to be redeemed, the Company shall deliver an Officer's Certificate to the Trustee setting forth the calculation of the Redemption Price or the manner in which the Redemption Price shall be calculated, as relevant, applicable to such redemption. The Trustee shall be under no duty to inquire into, may conclusively presume the correctness of, and shall be fully protected in relying upon, the applicable Redemption Price as so calculated, or the manner in which such Redemption Price shall be calculated, as relevant, and set forth in such Officer's Certificate.

Once notice of redemption is mailed by the Company, the Securities called for redemption will become due and payable on the applicable Redemption Date at the Redemption Price.

Notice of any redemption of the Securities shall be given in the manner and otherwise in accordance with the provisions of Section 404 of the Indenture to each Holder of Securities to be redeemed, at his address appearing in the Security Register, and that any such notice in lieu of stating the applicable Redemption Price, shall state the manner in which such Redemption Price shall be calculated. If the Company has given notice of redemption as provided in the Indenture and funds for the redemption of the Securities called for redemption have been made available on the Redemption Date referred to in that notice, such Securities will cease to bear interest on such Redemption Date (unless the Company defaults in the payment of the Redemption Price and accrued and unpaid interest). Any interest accrued to such Redemption Date will be paid as specified in such notice.

The Indenture contains certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of all series at the time Outstanding affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Outstanding Securities of all series, with respect to which any default under the Indenture shall have occurred and be continuing (voting as one class), on behalf of the Holders of all the Outstanding Securities of such series, to waive, with certain exceptions, such past default with respect to such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

------

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than a majority in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity.

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, I am of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Company is a validly existing as a corporation in good standing under the laws of the State of Missouri.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The Company has the corporate power and authority to issue the Notes, and the Notes have been duly authorized, executed and delivered by the Company.

Registration Statement on Form S-3

Registration No. 333-287024

Ladies and Gentlemen:

We have acted as counsel to Spire Inc., a Missouri corporation (the "***Company***"), in connection with the registration, pursuant to a Registration Statement on Form S-3, as amended (Registration No. 333-287024) (the "***Registration Statement***"), filed with the Securities and Exchange Commission (the "***Commission***") under the Securities Act of 1933, as amended (the "***Act***"), of the issuance and sale of $400,000,000 aggregate principal amount of the Company's 4.600% Senior Notes due 2031 (the "***Notes***") pursuant to the terms of an underwriting agreement dated February 4, 2026 (the "***Underwriting Agreement***") between the Company and the several underwriters named in Exhibit A thereto for whom BMO Capital Markets Corp., J.P. Morgan Securities LLC, Mizuho Securities USA LLC and U.S. Bancorp Investments, Inc. acted as representatives. The Notes were issued pursuant to the Company's Indenture (For Unsecured Debt Securities), dated as of August 19, 2014, between the Company and Regions Bank (as successor to UMB Bank & Trust, N.A.), as trustee (the "***Trustee***"), as amended or supplemented (the "***Indenture***"), including by the Fourth Supplemental Indenture thereto, dated as of the date hereof (the "***Supplemental Indenture***"), between the Company and the Trustee. This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act.

We have either participated in the preparation of or have reviewed and are familiar with, the Registration Statement, together with the exhibits thereto and the documents incorporated by reference therein, and the Prospectus dated May 7, 2025 forming part of the Registration Statement (the "***Prospectus***"), as supplemented by the Prospectus Supplement dated February 4, 2026, filed with the Commission pursuant to Rule 424(b) of the Act relating to the offering of the Notes (the "***Prospectus Supplement***"). We have also reviewed the Indenture, the form of global notes representing the Notes and the Underwriting Agreement (collectively, the "***Transaction Documents***"). In addition, we have examined originals or certified copies of such corporate records of the Company and other certificates and documents of officials of the Company, public officials and others as we have deemed appropriate for purposes of this letter.

We have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all copies submitted to us as conformed, certified or reproduced copies and the conformity of the Notes to the form thereof that we have reviewed. In our examination of documents, we have also assumed (a) the due organization, valid existence and good standing under the laws of its jurisdiction of organization of each party to the Transaction

------

Documents, (b) the legal capacity of natural persons, (c) the corporate or other power and due authorization of each of the Company and the other parties signatory thereto to execute, deliver and perform its obligations under the Transaction Documents, and to consummate the transactions contemplated therein, (d) the due execution and delivery of the Transaction Documents by all parties thereto and (e) that the Transaction Documents constitute the valid and binding obligation of each party thereto, other than the Company. As to various questions of fact relevant to this letter, we have relied, without independent investigation, upon, in the case of the Notes, certificates of public officials and certificates of officers of the Company, all of which we assume to be true, correct and complete.

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that upon (a) the due execution of the Notes by the Company, (b) the due authentication of the Notes by the Trustee pursuant to the Indenture, and (c) the delivery of the Notes against payment therefor in accordance with the Underwriting Agreement, the Notes will constitute valid and binding obligations of the Company.

The opinions and other matters in this letter are qualified in their entirety and subject to the following:

A. We express no opinion as to the laws of any jurisdiction other than the laws of the State of Missouri.

B. The matters expressed in this opinion are subject to and qualified and limited by (i) applicable
bankruptcy, insolvency, fraudulent transfer and conveyance, reorganization, moratorium and similar laws affecting creditors' rights and remedies generally; (ii) general principles of equity, including without limitation, concepts of
materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief (regardless of whether considered in a proceeding in equity or at law); and (iii) securities laws and public
policy underlying such laws with respect to rights to indemnification and contribution.

C. This opinion letter is limited to the matters expressly stated herein and no opinion is to be inferred or
implied beyond the opinion expressly set forth herein. We undertake no, and hereby disclaim any, obligation to make any inquiry after the date hereof or to advise you of any changes in any matter set forth herein, whether based on a change in the
law, a change in any fact relating to the Company or any other person or any other circumstance.

------

We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 8-K filed by the Company with the Commission on or about the date hereof, to the incorporation by reference of this opinion into the Registration Statement and to the use of our name in the Prospectus and the Prospectus Supplement, in each case forming a part of the Registration Statement and under the caption "Legal Matters." In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act and the rules and regulations thereunder.
