What’s new? Each year, we strive to improve our proxy disclosures to provide a broader and deeper understanding of Spire and how we think about governance, compensation and sustainability, as well as other topics of importance to our shareholders. We believe these disclosures will be beneficial as you vote this year. Inside, you’ll find updates on the following, among other topics:   •   A new director skills table, to improve transparency about the skills and experience of our Board of Directors   •   The new “pay versus performance” disclosure, which provides a new way of viewing the compensation of our named executive officers   •   Discussions of director and management succession planning, which were important to the appointment of a new president and chief executive officer, as well as two new independent directors and replacements for the chief compliance and legal officer

Dear fellow shareholders,

We are pleased to invite you to attend Spire’s 2024 Annual Shareholder Meeting, which is scheduled for Thursday, January 25, 2024, at 8:30 a.m., Central Standard Time. This year’s meeting will be held virtually and the accompanying proxy information outlines how to participate in the meeting as well as the matters that will be voted on at the meeting.

On behalf of the Board of Directors, thank you for your investment in Spire. It is our privilege to serve you, and we appreciate the responsibility and trust you place in us to help grow and guide the Company for continued success in the future. In fiscal year 2023, Spire’s management team remained focused on executing our business strategy through organic growth, investing in infrastructure and advancing through innovation to ensure we continue to provide value to our shareholders.

This past fiscal year once again brought challenges and change, both at Spire and within the energy industry. We navigated these challenges to deliver value for our shareholders, achieving basic net economic earnings of $4.06 per share. We also increased our annual dividend by 4.9%, making 2024 the 21^st year in a row we have increased our dividend.

During fiscal year 2023, Spire’s president and chief executive officer, Suzanne Sitherwood, announced her retirement, effective January 1, 2024. Following this announcement, the Board engaged an executive recruitment firm to assist the Board in conducting a thoughtful and comprehensive search for successors, including both internal and external candidates. The Board considered a number of well-qualified candidates and ultimately named Steven L. Lindsey Spire’s president and chief executive officer and appointed him to Spire’s Board of Directors, effective October 1, 2023. Mr. Lindsey served as Spire’s executive vice president, chief operating officer prior to becoming president and chief executive officer. Ms. Sitherwood remains on the leadership team as executive vice president, senior advisor, through her retirement date to assist in a smooth transition of leadership. The Board believes that Mr. Lindsey’s leadership and expertise will continue to support Spire’s vision and build upon the Company’s long-term strategy for success.

In addition to management succession planning, the Board remains focused on its oversight responsibilities, with an emphasis on identification and mitigation of material risks, while further developing and overseeing implementation of the Company’s growth strategy. The Board remains committed to ensuring the Board is made up of directors who are independent, committed, capable, diverse, experienced and accountable to our shareholders. Accordingly, we added two new directors to the Board in fiscal year 2023, each of whom brings skills and experience in areas that the Board identified as priorities prior to the director search process.

Spire is committed to engaging with investors to determine what information is most important to them, enhancing disclosures and making environmental, social and governance information even more accessible. Our 2022 Sustainability Report, released in June 2023, describes the progress the Company has made in achieving its sustainability goals and targets as well as our strategies to continue delivering on these goals. We invite you to review that report, which can be found on our website at SpireEnergy.com/Sustainability, for more information about these efforts.

Natural gas is a vital part of America’s energy future, so on behalf of the Board of Directors, thank you for your investment in Spire and for your continued support.

Sincerely,

Edward L. Glotzbach
Chair of the Board
Spire Inc.

Who we are

At Spire, we believe energy exists to help people. To warm homes, grow businesses and move communities forward. Every day, we’re inspired by our vision to make the breakthroughs today that will energize tomorrow.

As one of the largest publicly traded natural gas distribution companies in the country, we have the privilege of serving 1.7 million homes and businesses, as well as natural gas buyers, producers and industrial customers through our gas-related businesses. This commitment to serve is reflected in our mission to answer every challenge, advance every community and enrich every life through the strength of our energy. To live this mission, we hold strongly to our four values:

Safety	Drive	Inclusion	Integrity
We keep our people, company, customers and communities safe.	We lean into change, showing the courage and grit to make it happen.	We embrace and celebrate our differences to better understand each other and the world around us.	We do what’s right, every time.

Spire’s fiscal year 2023 corporate performance

The following table provides information on the Company’s performance in the last two fiscal years, which was a critical consideration in the Company’s determination of appropriate executive compensation. For the fiscal year ended September 30, 2023, the Company reported consolidated net income of $217.5 million ($3.85 per diluted share), compared with $220.8 million ($3.95 per diluted share) in fiscal year 2022. The $3.3 million decrease was driven by higher interest and other corporate costs. Net income and earnings per share are determined in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Management also uses the non-GAAP measure of net economic earnings (“NEE”) and NEE per share when internally evaluating and reporting results of operations as discussed on page 29 of the Company’s Annual Report on Form 10-K for the year ended September 30, 2023. NEE for fiscal year 2023 was $228.1 million ($4.05 per diluted share), up from $216.3 million ($3.86 per diluted share) for fiscal year 2022. The incremental $11.8 million was driven by increases in our Gas Marketing and Midstream segments, partially offset by unfavorable changes for the Gas Utility segment and other corporate costs. The results are discussed further beginning on page 30 of the 2023 Annual Report on Form 10-K.

Executive compensation

The Company is committed to its pay-for-performance philosophy, which we believe is closely aligned with shareholder interests by linking executive compensation to Company performance. The key metric used to determine funding under our annual incentive plan is adjusted operating income, and the metrics used to determine vesting under our long-term incentive plan are average net economic earnings per share and relative total shareholder return. The Company also emphasizes pay-for-performance by placing a majority of the executives’ target total direct compensation (“TTDC”) at risk through the annual and long-term incentive plans. TTDC includes the current base salary, the 2023 target annual incentive plan opportunity and the fair market value of the equity awards made during fiscal year 2023. Further, the value of the equity incentive award, the largest portion of incentive pay, is based on long-term performance.

Sustainability

We issued our fifth annual Sustainability Report in June 2023, which continued to expand our disclosures on environmental, social and governance topics. We included reporting under the Sustainability Accounting Standards Board (SASB) standards and increased disclosures aligned with the Task Force on Climate-Related Financial Disclosures (TCFD) recommendations. We held an investor sustainability call to discuss highlights from the report and give investors the opportunity to ask questions about our sustainability efforts. We remain committed to enhancing

Spire Inc.  |  2023 Proxy Statement     5

and expanding our disclosures to create an even more robust and transparent view of our overall sustainability strategy and plans.

In fiscal year 2023, the various committees of the Board of Directors continued formal oversight of management’s sustainability efforts in the areas of environmental; diversity, equity and inclusion; supplier diversity; and governance to ensure progress is being made on our sustainability commitments. The corporate governance committee remains responsible for overseeing and approving the Sustainability Report. The current Sustainability Report can be found on our website at SpireEnergy.com/Sustainability.

Qualifications required of all directors

The Board requires that each director be a person of high integrity with a proven record of success in his or her field and have the ability to devote the time and effort necessary to fulfill his or her responsibilities to the Company. Generally, the Board looks for persons who possess characteristics of the highest personal and professional ethics, integrity and values; an inquiring and independent mind; practical wisdom and mature judgment; and expertise that is useful to the Company and complementary to the background and experience of other Board members.

The Board considers diversity of race, ethnicity, gender, age, cultural background and professional experience in evaluating candidates for Board membership. Diversity is important because the Board believes that a variety of perspectives contribute to a more effective decision-making process.

When recommending director nominees for election by shareholders, the Board and the corporate governance committee focus on how the experience and skill set of each director nominee complements those of fellow directors to create a balanced Board with diverse viewpoints and deep expertise.

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     16

its business judgment to determine what is best for the Company in light of all the circumstances. Mr. Glotzbach is currently chair of the Board. A new Board chair will be elected at the January Board meeting in connection with Mr. Glotzbach’s retirement.

As chair, Mr. Glotzbach leads the Board in the performance of its duties by working with the chief executive officer to establish meeting agendas and content, engaging with the leadership team between meetings and providing overall guidance as to the Board’s views and perspective.

Mr. Lindsey, as chief executive officer effective October 1, 2023, focuses on setting the strategy for the Company, overseeing daily operations, developing our leaders and promoting employee engagement throughout the Company.

During fiscal year 2023, there were 13 meetings of our Board of Directors. All directors attended 75% or more of the aggregate number of meetings of the Board and applicable committee meetings, except as follows. Messrs. Ferrari and Koonce were not appointed to the Board until July 2023, and were not appointed to committees until August 2023. Mr. Borer attended nine out of 13 Board meetings during fiscal year 2023. The four meetings he missed all took place over a one-week period. Mr. Borer’s absence was due to a personal medical issue which is not anticipated to affect his attendance at future meetings. All directors attended the last annual meeting of shareholders other than Messrs. Ferrari and Koonce, who were not yet on the Board.

The standing committees of the Board of Directors include the audit, compensation and human resources, corporate governance and strategy committees.

Board evaluation process

How we evaluate our Board, committee and individual director performance

Conversations	Feedback shared	Feedback incorporated
In fiscal year 2023, Mr. Glotzbach, the Board chair, conducted individual conference calls with each director during which they discussed the performance of: (1) the Board, (2) each committee on which the director serves, and (3) each of the other individual directors. Mr. Glotzbach and each director also discussed what skills and attributes the Board should seek in future directors.	Mr. Glotzbach compiled and summarized the results of the conversations. He shared feedback with each committee chair regarding the performance of the respective committees, and he met with each director privately to discuss the input he received regarding their individual performance. The entire Board, including Ms. Sitherwood and Mr. Lindsey, discussed the feedback regarding the Board and the committees.	The corporate governance committee used the feedback about each director as a starting point for its conversation regarding which directors to nominate for reelection at the annual meeting. The directors agreed that this evaluation process allowed them to share their thoughts and input directly and transparently.

How we determine whether the Board has the right skills and experience

The corporate governance committee supports the Board in its development and maintenance of the Board succession plan. Each year, the corporate governance committee leads the Board in discussions regarding whether the Board possesses the appropriate mix of experiences, skills, attributes and tenure it needs to provide oversight and direction in light of the Company’s current and future business environment and strategic direction, all with the objective of recommending a group of directors that can best continue our success and represent our shareholders’ interests.

Through this process, the Board identified two candidates in fiscal year 2023 with skills that were deemed to be critical to the Board performing its oversight role, and these candidates were appointed to the Board. Vinny J. Ferrari and Paul D. Koonce were appointed to the Board in July 2023, and these new directors bring valuable expertise in cybersecurity, gas utility industry strategy, and executive and operating experience. The corporate governance committee and Board are committed to developing a diverse pool of potential candidates for future Board service and maintaining a diverse and well-rounded Board.

Spire Inc.  |  2023 Proxy Statement     17

Director onboarding and continuing education

In an effort to ensure the directors possess the necessary and appropriate skills and knowledge, all incoming directors participate in the Company’s orientation for new directors, which involves meetings between the new directors and leaders of various functional areas of the Company. The corporate governance committee also identifies educational programs on topics appropriate for public company board members, which the directors are encouraged to attend. Additionally, management arranges for speakers during Board and committee meetings to address timely topics, such as new legal and regulatory requirements that apply to the Company and industry updates. During the Board’s strategy sessions, directors hear presentations from, and engage in discussions with, speakers on numerous strategic and educational topics.

The Board, under the guidance of Mr. Glotzbach, has continued to develop a long-term Board succession plan that encompasses Board structure, mandatory and potential director and senior officer retirements, the evolving strategy of the Company, and the current and future skills and attributes required for the Board to effectively perform its oversight role.

Our Board has delegated certain of its responsibilities to committees to provide for more efficient Board operations and allow directors to engage in deeper analysis and oversight in specific areas. The members and committee chairs are appointed by the Board on recommendations from the corporate governance committee. The chair of each committee helps develop the agenda for that committee and updates the Board after each regular committee meeting and otherwise as appropriate.

Risk oversight

Management is responsible for assessing and managing risk exposures on a day-to-day basis, and the Board is responsible for overseeing the Company’s risk management. In its oversight role, the Board and its committees ensure the Company promotes a risk-aware culture and decision-making process. More specifically, the Board has oversight responsibility for the Company’s overall business risk management process, which includes the identification, assessment, mitigation and monitoring of key business risks on a companywide basis. The Board has delegated certain risk oversight responsibilities to its committees:

Audit committee	Compensation and human resources committee	Corporate governance committee	Strategy committee
Oversees risks associated with financial and accounting matters, including: •  Compliance with all legal and regulatory requirements; and •  Internal control over financial reporting.	Oversees risks associated with the Company’s: •  Compensation policies and practices, and ensures incentives and other forms of pay do not encourage unnecessary or excessive risk-taking; •  Executive officer succession planning; •  Pension plan funding; and •  Culture and workforce composition.	Oversees risks associated with corporate governance, including: •  Board leadership structure; •  Director succession planning; and •  The Sustainability Report.	Oversees risks associated with the Company’s: •  Long-range plan, investment strategies, capital structure and financial needs; •  Growth strategies; and •  Plan and efforts to be a carbon neutral company by midcentury, as well as other related environmental initiatives.

At the management level, the Company has an officer charged with overseeing the implementation of the enterprise risk management process at the Company. The officer’s efforts are supported by the Board of Directors, executive leadership and several other leaders across the Company who guide the effort to develop, document and maintain risk mitigation plans. A risk committee also meets throughout the year to assist in identifying, prioritizing and monitoring risks.

Because of the use of commodity-based derivatives by three of the Company’s subsidiaries, there is also a risk committee that focuses on the risks and exposures in the commodity-based derivatives markets. Senior leaders of the Company receive periodic updates on the activities of the risk committees, as well as prompt notice of events that may require immediate action by the Company.

Cybersecurity

Cybersecurity is a priority addressed by the full Board at every regular Board meeting with the relevant functional leaders of the Company, including in-person reports by the chief information officer and the managing director of information security. The Board receives and discusses these reports, which focus on the cybersecurity program and related risks, and provide an update on any cybersecurity events or occurrences. Management also provides updates to the Board between regular Board meetings to the extent events warrant. These updates and discussions enable the Board to oversee and manage the Company’s cybersecurity risks.

The Company’s cybersecurity program includes a process staffed by senior legal, technology, risk and security leaders to evaluate, escalate and communicate cybersecurity incidents. Management also conducts annual phishing exercises, security awareness training, external penetration testing and tabletop exercises, and reviews metrics monthly.

Spire Inc.  |  2023 Proxy Statement     21

Compensation risk assessment

Every year, management, with oversight by the compensation and human resources committee, conducts a risk assessment of the Company’s compensation programs, policies and practices for its employees, including the Company’s executive compensation program and practices. This risk assessment includes consideration of the mix and amount of compensation:

• in cash and equity;

• with short-term and long-term performance goals;

• with individual, business unit, safety and corporate performance objectives; and

• dependent on financial and non-financial performance measurement.

The assessment also considers the risk mitigation impact of stock ownership guidelines and retention requirements, Company stock trading and blackout policies, the use of multiple types of metrics, the caps set on incentive compensation, and the role of the compensation and human resources committee and its independent consultant.

Management regularly assesses risks related to our compensation programs, including our executive compensation programs. At the compensation and human resources committee’s direction, its independent compensation consultant Semler Brossy and management provide ongoing information regarding compensation factors that could mitigate or encourage excessive risk-taking.

In fiscal year 2023, management determined, and the compensation and human resources committee agreed, that the risks relative to the Company’s compensation policies and practices would not result in a material adverse effect on the Company.

Director independence

The Board of Directors believes a majority of the directors should be independent and determined the following members are independent: Borer, Ferrari, Fogarty, Glotzbach, Hightman, Jones, Koonce, Newberry, Schwartz, and Stupp. Mr. Lindsey, the Company’s president and chief executive officer, and Ms. Sitherwood, the Company’s former president and chief executive officer, are the only non-independent members of the Board. Ms. Sitherwood announced her resignation from the Board effective January 1, 2024 in connection with her retirement from the Company. In determining the independence of directors, the Board found that none of the directors, other than Mr. Lindsey or Ms. Sitherwood, have any material relationship with the Company other than as a director.

In making these determinations, the Board considers all facts and circumstances as well as certain prescribed standards of independence, which are included with our Corporate Governance Guidelines at www.SpireEnergy.com in the Investors/Governance section. The Director Independence Standards adopted by the Board largely reflect the New York Stock Exchange standards, except our adopted standards provide that the Board need not consider material the provision of natural gas service to any director or immediate family member of the director or director-related company pursuant to the tariffed rates of the Company’s utilities.

The independent members of the Board meet in executive session at least quarterly, which sessions are led by Mr. Glotzbach, the current chair of the Board. Each quarter, the chair solicits from other Board members topics for discussion in those sessions. Topics include the performance of the chief executive officer, executive succession planning, executive compensation matters, Board succession planning and the Company’s strategy.

All the members of the audit, compensation and human resources, and corporate governance committees are independent under our Director Independence Standards as well as under the standards of the New York Stock Exchange.

Related Party Transaction Policy and Procedures

Our Related Party Transaction Policy and Procedures is used by our corporate governance committee to determine whether to pre-approve transactions with our directors, executive officers, 5% or greater shareholders, and their immediate family members. The corporate governance committee reviews all such transactions, regardless of amount. Based on its consideration of all the relevant facts and circumstances, the committee will decide whether or not to approve the transaction and will approve only those transactions it determines to be in the best interest of the Company.

If the Company becomes aware of an existing transaction with a related party that has not been approved under the policy, the matter will be referred to the committee. The committee will evaluate all options available, including

Spire Inc.  |  2023 Proxy Statement     23

ratification, revision or termination of such transaction. The policy also includes certain transactions that are deemed pre-approved because they do not pose a significant risk of a conflict of interest. Such pre-approved transactions include the provision of natural gas service to any of the related parties by our utility subsidiaries in accordance with their respective tariffed rates and those transactions at such a level as not to be material to the Company or the related party.

Consistent with Securities and Exchange Commission (SEC) requirements regarding accountant independence, the audit committee recognizes the importance of maintaining the independence, in fact and appearance, of our independent registered public accountant. To this end, the audit committee adopted a policy to pre-approve all audit and permissible non-audit services provided by the independent accountant.

Under the policy, the committee or its designated member must pre-approve services prior to commencement of the specified service. Any pre-approvals by the designated member between meetings will be reported to the audit committee at its next meeting. The requests for pre-approval are submitted to the audit committee or its designated member, as applicable, by both the independent accountant and the Company’s chief financial officer or designee and must include (i) written description of the services to be provided in detail sufficient to enable the audit committee to make an informed decision with regard to each proposed service, and (ii) joint statement as to whether, in their view, the request or application is consistent with the SEC’s and Public Company Accounting Oversight Board’s (PCAOB) rules on auditor independence.

The pre-approval fee levels are established and reviewed by the audit committee periodically, primarily through a quarterly report provided to the audit committee by management. Any proposed services exceeding these levels require specific pre-approval by the audit committee. Generally, after review of the pre-approved services incurred each quarter, the audit committee resets the pre-approval dollar level. At each regularly scheduled audit committee meeting, the audit committee reviews the following:

• a report provided by management summarizing the pre-approved services, or grouping of related services, including fees; and

• a listing of newly pre-approved services since its last regularly scheduled meeting.

Audit committee’s review of independent auditor

The audit committee is directly responsible for the appointment, oversight, qualification, independence, performance, compensation and retention of the Company’s independent registered public accounting firm, including audit fee negotiations and approval. An important element of this oversight is the lead client service partner’s quarterly meetings with Ms. Fogarty, the audit committee chair, and monthly meetings with Mr. Glotzbach, who serves on the audit committee and chairs the Board.

Annually, the committee evaluates whether retaining Deloitte as the Company’s independent auditor for the upcoming year is in the best interest of Spire and its shareholders. As part of this analysis, the committee considers, among other factors:

• how effectively Deloitte is maintaining its independence as demonstrated by exercising judgment, objectivity and professional skepticism;

• the quality, candor, timeliness and effectiveness of Deloitte’s communications with the committee and management;

• the adequacy of information provided on accounting issues, auditing issues and regulatory developments affecting utility companies;

• the lead client service partner’s performance;

• whether Deloitte’s known legal risks include involvement in proceedings that could impair its ability to perform the annual audit;

• reports of the PCAOB and other available data regarding the quality of work performed by Deloitte;

• the ability of Deloitte to meet deadlines and respond quickly;

• the geographic reach and expertise of Deloitte in terms of quantity, quality and location of staff;

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     24

• Deloitte’s long tenure and experience as the Company’s auditor; and

• the historical and proposed Deloitte fees charged to the Company.

The committee also factors in the relative costs, benefits, challenges, overall advisability and potential impact of selecting a different independent public accounting firm.

As part of its role in overseeing the external auditors, the committee is responsible for the selection of the Deloitte lead client service partner, and as required by law, ensures rotation of the lead partner every five years. At the beginning of the new lead partner selection process, Deloitte provides a list of candidates to members of senior management, who, in turn, evaluate and interview the candidates and submit a recommendation to the committee. The committee considers senior management’s recommendations and those of Deloitte leadership; evaluates the qualifications, strengths and weaknesses of the candidates; and selects the lead client service partner.

Other key governance policies and practices

Plurality voting

The Company’s bylaws provide for plurality voting in the event the election of directors is contested.

Director resignation

The Company’s bylaws require that if a nominee for director who is an incumbent director is not elected and no successor has been elected at such meeting, the director must promptly tender his or her resignation to the Board of Directors. The corporate governance committee is required to make a recommendation to the Board as to whether to accept or reject the tendered resignation, or whether other action should be taken.

Board of Directors Succession Planning and Diversity Policy

The Board has adopted a written policy acknowledging the importance of diversity in its broadest sense in the boardroom as a driver of Board effectiveness. Diversity encompasses diversity of perspective, experience, background (including nationality), personality type, cognitive and personal strengths and other personal attributes, as well as diversity of gender, social and ethnic backgrounds.

During the past year, our Board’s succession planning efforts have focused primarily on the composition of our Board and its committees; the individual skill sets of current members and additional skills that could be beneficial for the Board and its committees in light of the Company’s strategy and emerging risks; upcoming retirements under our director retirement policy; our commitment to Board diversity; and strategies for identifying and recruiting new directors. The Board has also focused specifically on succession planning for the Board chair and committee chair roles.

Each director provided written input in response to a survey distributed by the corporate governance committee soliciting thoughts concerning the skills and attributes the Board and individual directors should possess. The Board’s subsequent conversations and approach were informed by the results of this survey, our Company’s engagement with shareholders and other stakeholders as well as the Board’s annual self-evaluation and director nomination processes.

Our Board is focused on balancing new perspectives and the experience of existing directors while undergoing an orderly transition of roles and responsibilities on the Board and its committees. The Board conducted a director search in 2023 based on desirable skills and experience that had been identified by the Board, and appointed Vinny J. Ferrari and Paul D. Koonce to the Board in July 2023. These directors bring expertise in cybersecurity, gas utility industry strategy, and executive and operating experience that the Board believes will complement and enhance the existing experience on the Board.

Spire Inc.  |  2023 Proxy Statement     25

Management succession planning

Succession planning for the CEO and executive officers is directly overseen by the Board and the compensation and human resources committee, which conducts an annual review of the succession plans for our CEO and other executives and receives periodic updates on the plans. Our CEO and the compensation and human resources committee, in turn, review the succession plans annually with the full Board.

The Board engaged in a robust CEO search process during fiscal year 2023 after Ms. Sitherwood announced her plans to retire effective January 1, 2024. The Board engaged an executive recruitment firm to assist in conducting a nationwide search, which included a diverse pool of both external and internal candidates. The Board identified the top skills and qualities that would be important for the Company’s next CEO, and also relied on third-party leadership assessments to ensure that any candidates would be a strong fit for the Company. After completing this search, the Board named Steven L. Lindsey as president and CEO, effective October 1, 2023. Mr. Lindsey had served as executive vice president, chief operating officer for the Company prior to being named president and CEO. Mr. Lindsey’s appointment reflects the strength of the Company’s succession planning process.

In addition, Mr. Darrell’s retirement on December 1, 2023, was anticipated by the Board and management due to Mr. Darrell reaching normal retirement age, and the Company’s succession planning process resulted in two internal candidates being named to assume Mr. Darrell’s responsibilities as Chief Compliance and Legal Officer.

A key responsibility of the CEO and the Board is ensuring an effective process is in place to provide continuity of leadership over the long term at all levels of the Company. To that end, management implemented an updated succession-planning program throughout Spire during fiscal year 2023.

These succession plans reflect the Board’s belief that internal candidates for the CEO and other executive positions should be regularly identified and that diverse candidates should be developed for consideration when a transition is planned or necessary. Accordingly, management has identified internal candidates in various phases of development and has implemented development plans to ensure the candidates’ readiness.

The development plans identify the candidates’ strengths and developmental opportunities, and the compensation and human resources committee receives periodic updates and regularly reviews the candidates’ progress. As part of the process, the Board engages with potential successors at Board meetings and in less formal settings to allow directors to personally assess candidates. Although Spire prefers to develop successors from existing employees, the Company may recruit externally if doing so would better suit strategic needs.

The compensation and human resources committee believes the Company’s succession planning process provides a good structure to ensure that the Company will have qualified successors for its executive officers. The Board has adopted a plan that establishes the process for addressing the unexpected absence of the CEO that may occur as a result of death, illness, disability or sudden departure. This plan also addresses the unexpected absence of key executive officers and the chair of the Board.

Clawback policies

We have a policy that addresses recoupment of amounts from executive officers’ and other employees’ performance-based awards under the annual and long-term incentive plans to the extent that they would have been materially less were it not for financial statement errors, fraud or intentional, willful or gross misconduct.

In October 2023, the Board adopted a second clawback policy that complies with the requirements set forth by the Securities and Exchange Commission and the New York Stock Exchange regarding the recoupment of incentive compensation in the event of an accounting restatement. The new policy can be found as an exhibit to the 2023 Annual Report on Form 10-K.

Prohibition of hedging/pledging of stock

Our policy on the purchase and sale of securities prohibits executive officers and board members from: (i) entering into hedging transactions with respect to Company securities, including, without limitation, through the use of financial instruments such as exchange funds, prepaid variable forwards, equity

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     26

swaps, puts, calls, collars, forwards and other derivative instruments, or through the establishment of a short position in the Company’s securities; and (ii) holding Company stock in a margin account or pledging Company stock as collateral for a loan. Negative pledges are not prohibited by this policy.

Board engagement with management

On a monthly basis, Mr. Glotzbach, the chair of the Board, meets with our CEO and certain members of the management team, depending on the topics to be discussed. This is an opportunity for management to have timely conversations with the chair regarding key Company updates. The topics discussed typically include progress on strategic initiatives, leadership development and management succession planning, governance items and financial updates. Mr. Glotzbach is also accessible to management on an as-needed basis between monthly meetings to provide guidance and oversight on key, time-sensitive issues. Committee chairs are similarly available to management on an as-needed basis.

Shareholder outreach

Our investor relations and corporate governance teams reach out to our largest institutional investors biannually, seeking their input and feedback regarding governance topics and our disclosure practices. This year, we specifically requested feedback on our sustainability efforts and related disclosures. We continue to seek input and guidance on our proxy statement and governance practices and disclosures, as well.

Directors’ compensation

The corporate governance committee periodically reviews director compensation relative to data of the Company’s comparator group. The basic retainers and fees payable in fiscal year 2023 are set forth below. No retainers or fees are paid to directors who are executives or employees of the Company and its subsidiaries.

Annual Board cash retainer	$100,000
Annual Board stock retainer	120,000
Chair of the Board annual retainer	100,000
Audit committee chair annual retainer	15,000
Compensation and human resources committee chair annual retainer	15,000
Corporate governance committee chair annual retainer	13,000
Other committee chair annual retainer	13,000

The amount and form of the annual Board retainer are fixed annually by vote of the Board. Each year, the corporate governance committee reviews peer and market research on amounts and structure of board of director fees and makes a recommendation to the Board regarding the amount and structure of the Board fees.

Since February 1, 2022, the annual retainer has been $220,000, of which the cash portion is $100,000 and $120,000 is payable in shares of our common stock. The number of shares is determined by dividing the total equity grant value by the closing stock price of our common stock on the grant date and rounding to the nearest 10 shares. There are no additional meeting fees. The directors’ stock ownership requirement is six times the annual cash retainer.

After a review of director compensation was performed by Total Rewards Strategies, an independent compensation consultant, the Board determined that peer company data supported an increase in director compensation. Effective February 1, 2024, the annual retainer will increase to $230,000, of which the cash portion is $105,000 and $125,000 is payable in shares of our common stock. The annual retainer for the Chair of the Board will increase to $105,000, the annual retainer for the chair of the audit committee will increase to $18,000, the annual retainer for the chair of the compensation and human resources committee will increase to $16,000, and the annual retainer for the chairs of the corporate governance and strategy committees will increase to $15,000.

The Company’s Deferred Income Plan (“DIP”) allows directors to elect to defer all or a portion of their annual fees and equity awards. If a director elects to defer all or a portion of the annual equity grant, the deferred portion is awarded as phantom shares, and upon vesting an amount of money equal to the value of the shares at vesting is credited to the Company Stock Fund in the director’s DIP account. Dividends paid on deferred equity are credited to the director’s DIP account to any fund instructed by the director other than the Company Stock Fund. Directors may not transfer deferred equity out of the Company Stock Fund until after they retire from the Board. Directors who elect to defer all or a portion of their annual Board fees may invest their deferred fees in any fund in the DIP other than the Company Stock Fund.

The Board has imposed a limit of $400,000 per director on the annual amount of the restricted stock retainer that could be approved by the Board for payment to independent directors. The table below discloses the compensation paid or earned by all those who served as Company directors in fiscal year 2023. Not included in the table is the Retirement Plan for Non-Employee Directors, in which participation and benefits have been frozen since November 1, 2002. Under that plan, a non-employee director who had at least five years of service as a director of the Company or its predecessor as of November 1, 2002, qualified for an annual payment after retirement in an amount equal to the Board retainer on November 1, 2002 ($18,000), with such payments being made for the longer of 10 years or life. Ms. Van Lokeren, who retired from the Board on January 26, 2023, was the only director eligible under this plan.

Proposal 2: Advisory vote to approve the compensation of our named executive officers

As required pursuant to Section 14A of the Securities Exchange Act of 1934, as amended, we are seeking your approval of the Company’s compensation of the named executive officers as disclosed in this proxy statement. Although the vote on this proposal is advisory and nonbinding, the compensation and human resources committee and Board will review the results of the vote and consider the collective views of our shareholders in future determinations concerning our executive compensation program generally and the compensation of our named executive officers in particular.

As noted in the following Compensation Discussion and Analysis, the Company’s philosophy is to pay for performance by making compensation decisions based on what promotes our corporate strategy, creates shareholder value and remains equitable for the Company, its employees and its shareholders. In the process of making these decisions, we also consider the types and levels of compensation in the marketplace. We urge you to read the Compensation Discussion and Analysis section of this proxy statement, which discusses in more detail our compensation policies and procedures. Throughout the year, our compensation and human resources committee assesses our compensation programs to ensure they are consistent with our pay philosophy. In determining how to vote on this proposal, please consider our compensation governance and pay structure:

• Compensation balance: Most of the compensation to the named executive officers is aligned with corporate performance. The Company seeks to balance short-term (cash) and longer-term (equity) compensation opportunities to ensure the Company meets short-term objectives while continuing to produce value for its shareholders over the long term.

• Clawback: Our policy addresses recoupment of amounts from executive officers’ and other employees’ performance-based awards under the annual and equity incentive plans to the extent that they would have been materially less were it not for financial statement errors, fraud or intentional, willful or gross misconduct. We also have a separate clawback policy that complies with the SEC and New York Stock Exchange requirements to recoup compensation in the event of an accounting restatement.

• Prohibition of hedging/pledging of stock: Our policy on the purchase and sale of securities prohibits executive officers and Board members from (i) entering into hedging transactions with respect to Company securities, including, without limitation, through the use of financial instruments such as exchange funds, prepaid variable forwards, equity swaps, puts, calls, collars, forwards and other derivative instruments, or through the establishment of a short position in the Company’s securities; and (ii) holding Company stock in a margin account or pledging Company stock as collateral for a loan.

• Stock ownership requirements: Our stock ownership requirements, which are outlined on page 31, further strengthen the alignment of our executives with our shareholders.

• Independent compensation consultant: The compensation and human resources committee’s consultant is independent.

• Modest perquisites: The Company’s use of perquisites is modest.

• Caps on incentive awards: We have limits on incentive compensation, which cap all potential annual incentive plan awards at 150% of target and all equity incentive plan awards at 200% of target.

• No employment agreements or excise tax gross-up: The Company does not enter into employment agreements or provide excise tax gross-up protections.

• No additional years of service credited: The supplemental pension plans are traditional plans that cover the compensation not included in the qualified pension plan due solely to tax limitations, and do not otherwise factor in additional compensation or additional years of service.

The Board of Directors is asking shareholders to support the Company’s named executive officer compensation as disclosed in this proxy statement. The compensation and human resources committee and the Board of Directors believe the compensation program effectively implements the Company’s compensation principles and policies, achieves the Company’s compensation objectives, and aligns the interests of the executives and shareholders. Accordingly, the Board asks shareholders to cast a nonbinding vote “FOR” the following resolution:

Executive summary

2023 Company performance

The compensation and human resources committee (“Committee”) believes the actions taken by the Company’s chief executive officer (“CEO”) and management team throughout fiscal year 2023 positively impacted the Company’s results and positioned the Company for continued success. Please see the discussion of Spire’s fiscal year 2023 corporate performance on pages 4-5 for more information about the financial results that affected compensation outcomes for fiscal year 2023. Adjusted operating income and net economic earnings per share are both closely linked with incentive pay, which reflects our intention that executive compensation results are aligned with corporate financial performance.

Alignment of pay and performance

The Company is committed to a pay-for-performance philosophy, and amounts earned by the NEOs under the Annual Incentive Plan (“AIP”) have a direct correlation to corporate performance. Adjusted operating income is the key metric used to determine funding under the Company’s AIP. Further explanation of adjusted operating income is provided on page 40 of this proxy statement. Prior to fiscal year 2022, the metric used to determine funding was net economic earnings per share, which is still used as a metric for the long-term incentive plan, and is further discussed on page 42 of this proxy statement.

The Company also emphasizes pay for performance by placing a majority of the NEOs’ target total direct compensation (“TTDC”) at risk through the annual and long-term incentive plans. TTDC includes base salary as of the end of fiscal year 2023, the 2023 target AIP opportunity and the fair market value (target shares multiplied by grant date fair value) of awards granted under the 2015 Equity Incentive Plan (“EIP”) during fiscal year 2023. Furthermore, the value of the equity incentive awards, the largest portion of incentive pay, is based on the Company’s long-term performance. The graph below shows the mix of fixed (base pay) and at-risk (annual and long-term incentive) pay, including how much of the long-term incentive pay is performance-based.

Compensation overview and philosophy

The Committee establishes the executive compensation philosophy and assists the Board in the development and oversight of all aspects of executive compensation.

Pay-for-Performance	Balance	Competitiveness
The compensation program should promote our corporate strategy and create shareholder value.	Annual and long-term incentive opportunities should reward the appropriate balance of short- and long-term financial, strategic and operational business results.	The compensation program should be sufficiently competitive to attract, retain and motivate a leadership team capable of maximizing Company performance.

Our pay-for-performance compensation philosophy promotes our corporate strategy and shareholder value, while remaining equitable for the Company, its executives and its shareholders. The Committee believes its compensation practices reflect a responsible pay-for-performance culture. The Committee seeks to deliver a total compensation package that balances short-term and longer-term compensation opportunities to ensure the Company meets short-term objectives while continuing to create value for its shareholders over the long term.

The Committee also promotes a competitive compensation program to attract, motivate and retain key executives. Each year, the Committee reviews the Company’s pay program for its executive officers to evaluate total compensation relative to the Company’s peer group. The Company’s compensation philosophy is to position target total compensation in the median range of peer comparator data, with actual pay dependent on Company results and the executive’s performance, skills and experience.

The Committee considered the results of the January 2023 shareholder advisory “say-on-pay” vote when making compensation decisions. A majority (97.87%) of the votes cast approved the compensation program described in the Company’s 2022 proxy statement. The judgment of the Committee, which included taking into account the support from the shareholder vote, was that no significant changes to the executive compensation program were warranted as a direct result of shareholder feedback. The Committee also considered the results of the January 2023 shareholder advisory vote on the frequency with which the Company should seek shareholder advisory approval of executive compensation, and determined it would continue to request advisory shareholder approval on an annual basis.

Best practices in executive compensation

Our executive compensation program reflects the following best practices, which ensure effective compensation governance and align the interests of our shareholders and executives.

What we do
	Executive annual incentive plan (AIP) awards are capped at 150% of target
	Total grant value under the equity incentive plan (EIP) is capped at 200% of target
	A majority (75%) of long-term incentive compensation (shares and value) is performance-contingent
	Time-based equity awards are granted with a three-year cliff vesting schedule
	Non-vested equity awards are not accelerated after a change in control unless the executive is terminated, or the award is not assumed or substituted by the successor company (i.e., double trigger)
	Executives and directors are subject to stock ownership guidelines and retention requirements
	Our executive severance program standardizes severance benefits and limits benefit triggers to termination by the Company without cause or the participant’s resignation for good reason
	Our clawback policy applies to all executive officers for performance-contingent awards made under the AIP and EIP

What we don’t do
	No employment agreements with executives
	No excise tax gross-ups for executives
	No dividends on performance-contingent stock awards prior to vesting
	No hedging or pledging of Company stock
	No excessive perquisites for executives

Components of executive compensation

The table below provides the components and objectives of the Company’s executive compensation program.

Element	Purpose/Objective	Key features	Performance measures
Base salary	Designed to attract and retain key executive talent and to reward leadership effectiveness	•  Fixed portion of annual compensation	Based on factors deemed relevant by the Company, including: •  job responsibilities and performance in his or her position •  level of experience and expertise in a given area •  role in developing and executing corporate strategy •  current leadership •  comparison of salaries for similar positions at comparator companies
Annual cash incentive	Designed to motivate and reward short-term annual results tied to corporate, safety and individual performance objectives	•  Targets are a percentage of base salary, and awards are paid in cash •  Actual payouts may range between 0%-150% of target, based on actual results relative to metrics	Varied weightings of corporate and individual performance metrics, depending on the individual’s role and position within the Company, and standard weighting of safety metric for all executives. The corporate metric used for the AIP is adjusted operating income, and the safety metric is based on the OSHA DART rate, at-fault motor vehicle accident rate and the total recordable injury rate.
Long-term incentives	Designed to encourage retention and further tie executive compensation to stock appreciation and long-term company performance	•  25% time-based restricted shares (“TBRSs”)	Three-year cliff vesting period to encourage retention and further tie executive compensation to stock appreciation during that vesting period
		•  75% performance-contingent stock units (“PCSUs”) •  Actual payouts may range between 0%-200% of target, based on actual results relative to metrics	PCSUs vest based on the average net economic earnings per share over a three-year period, as well as total shareholder return performance relative to peer group over the same period. These metrics are weighted at 25% of the award being based on average net economic earnings per share, and 75% of the award being based on relative total shareholder return.

In making decisions about compensation, the Committee reviews market and peer group data, as well as additional analysis provided by the Committee’s independent compensation consultant. The Committee also considers the role, experience and expertise of each executive officer.

Using this data, the Committee determines whether to make certain market adjustments to base salaries and sets target opportunities under the annual and long-term incentive programs that, when combined, produce TTDC that is consistent with the Company’s compensation philosophy.

Analysis of 2023 compensation decisions and actions

Base salary

In November 2022, the Committee approved increases to certain NEO salaries for fiscal year 2023, ranging from 3 to 3.5%. Some NEO salaries were not increased for fiscal year 2023 due to market considerations. The salaries for the NEOs are detailed previously in the “Summary of 2023 compensation decisions for NEOs” section. The Committee believed that these salary increases reflected the NEOs’ contributions to successful business growth while maintaining a focus within the NEOs’ functional areas.

Annual incentive compensation

At the beginning of each fiscal year, the Board reviews and sets key performance metrics for the AIP based on the Company’s business and strategic plan for the upcoming year. Actual payments to executives are then based on the Company’s fiscal year results as well as the executive’s individual performance. The Committee, in collaboration with management, sets the targets for the corporate and safety metrics described below, based on an analysis of prior years’ performance and a focus on achieving financial growth and improvement in safety performance in future years. Individual performance is reviewed by the Committee and is based on accomplishments related to the executive’s functional area of responsibility, execution of corporate strategy and financial results.

Progress on the AIP metrics is reviewed periodically during the year, and the Committee reviews the final results shortly after the end of the fiscal year but awaits the audit certification before approving the final payouts. Rarely, some discretionary adjustments may be applied, where appropriate, and there are instances where individual objectives may be modified during the year. No discretionary adjustments were applied for fiscal year 2023.

The following chart sets forth the 2023 AIP targets as a percentage of base salary and the weightings of the corporate, safety and individual metrics for each NEO.

Corporate metric

The metric used in determining the corporate performance portion of AIP awards is adjusted operating income, which is a key measure of the Company’s financial success for the fiscal year and is a common metric used for short-term incentives within the industry⁽¹⁾. The corporate metric also includes a weighting mechanism for each business unit in order to prevent extremely high or low performance from a smaller business unit from having a disproportionate impact on the overall results. Adjusted operating income for AIP purposes is based on operating income for three categories of business units (Gas Utility, Spire Marketing and Spire Midstream), and the results are weighted by the budgets for each category of business unit. Adjusted operating income removes the impacts related to acquisition, divestiture and restructuring activities, mark-to-market adjustments, and other non-operational and non-recurring items. The Committee and management believe these adjustments provide a useful representation of the economic impact of the overall results of ongoing operations.

(1) As adjusted operating income is a non-GAAP metric, the reconciliation to operating income can be found on Schedule A to this proxy statement.

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     40

The table below shows the levels of threshold, target and high performance for the corporate metric for fiscal year 2023, as well as the resulting payout percentage after the business unit weighting mechanism has been applied.

Corporate metric	Threshold performance	Target performance	High performance	Actual performance	Resulting corporate metric payout percentage
Adjusted operating income (millions)	$363.0	$410.6	$459.0	$441.3	84.5%

Safety metric

The safety metric, which has a weighting of 10% for all officers, sets goals for the Company’s OSHA DART rate, at-fault motor vehicle accident rate, and the total recordable injury rate. Safety is a core value at Spire, and we will continue to set ambitious goals with the focus of continuous improvement in all areas of safety. In fiscal year 2023, our safety results were below target, resulting in a 0% payout for this metric. The Company is focused on improving these results in future years, and has added a leadership engagement element to the safety metric beginning in fiscal year 2024. The fiscal year targets and results are shown below.

Metric (weighting)	FY23 Target	FY23 Actual
OSHA DART Rate (45%)	1.35	1.87
At-Fault Motor Vehicle Accident Rate (35%)	3.07	3.45
Total Recordable Injury Rate (20%)	2.55	3.88
Total Payout Percentage: 0%

Individual performance metric

Individual performance measures are generally subjective and relate to the manner in which the executive leads his or her teams to accomplish key business and strategic results during the year. This allows for assessment of the executive’s leadership role in furthering the values and culture of the Company as well as contributing to its long-term success. The individual performance metric results for each NEO were based on the achievements identified previously in the “Summary of 2023 compensation decisions for NEOs” section.

Fiscal year 2023 AIP results

After evaluating the performance of the Company and the NEOs in fiscal year 2023, the Committee approved annual incentive awards. AIP payouts are capped at 150% of target. These AIP awards reflect the NEOs’ strong leadership to strategically operate the business during a fiscal year that presented unique challenges and changes. As a result of the performance on the metrics described herein, the NEOs earned the following amounts under the AIP.

	Corporate		Safety		Individual		Total annual incentive plan payout		Total annual incentive plan payout as % of target
Sitherwood		$603,805		$—		$142,913		$746,718		78	%
Rasche		162,111		—		66,409		228,520		77
Lindsey		252,404		—		72,116		324,520		76
Darrell		120,036		—		46,168		166,204		76
Geiselhart		116,540		—		66,306		182,846		86

Long-term incentive compensation

The Committee approves equity grants with approximately 75% of the value of long-term incentives being awarded in performance-contingent stock units (“PCSUs”) and approximately 25% of the value being awarded in time-based restricted shares (“TBRSs”). The Committee bases the size of equity awards on its assessment of a market-based analysis of TTDC for each NEO, as further discussed in the “Competitive market compensation analysis” section herein.

Spire Inc.  |  2023 Proxy Statement     41

The number of PCSUs that vest is determined based on two metrics. The first is a Total Shareholder Return (“TSR”) metric that compares the Company’s TSR performance to its peer group over a period of three fiscal years (described herein on pages 46-47). The second is the average basic net economic earnings per share (“NEEPS”) over the same three-year period. Net economic earnings exclude from net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisitions, divestiture and restructuring activities, and the largely non-cash impacts of impairments and other non-recurring or unusual items, such as certain regulatory, legislative or GAAP standard-setting actions.⁽²⁾

The threshold, target and high-performance levels set for EIP grants are considered to be confidential and competitive information, particularly to the extent the performance targets relate to projected Company financial data and strategy, neither of which the Company publicly discloses. The Committee believes that targeted levels of performance for the EIP grants are challenging and will not be achieved all the time. The high-performance level will be difficult to achieve and will require exceptional performance. The following chart shows the vesting levels for prior fiscal years as a percentage of target.

Performance period (fiscal years)	Percentage of target at which grants vested
2017–2019		97	%
2018–2020		71
2019–2021		121
2020–2022		85
2021–2023		89

With regard to the Committee’s certification of performance, the Committee, which is comprised solely of independent directors, reviews and discusses the calculations of the metrics to verify compliance with the terms of the awards that were set at the time the awards were granted and determines the level of performance achieved and the number of shares earned. The Committee then approves a resolution that reflects the Committee’s determinations. The PCSUs will vest only upon the Committee’s certification as to performance.

Grants made in fiscal year 2023

On November 10, 2022, the Board authorized the grants of TBRSs (“2023 TBRSs”) and PCSUs (“2023 PCSUs”) to 29 officers, including all the NEOs. The grants were made on November 18, 2022. Both the 2023 TBRSs and the 2023 PCSUs are included in the “Grants of plan-based awards” table in this proxy statement. The fair market value of these grants is included in the “Summary of 2023 compensation decisions for NEOs” section and is also found in the “Stock awards” column of the “Summary compensation table.”

The 2023 TBRSs fully vest on the third anniversary of the grant date if the recipient remains continually employed with the Company through that date. Quarterly dividends are paid on TBRSs during the vesting period.

The 2023 PCSUs consist of stock units that become eligible to vest following the end of the applicable three-year performance period, but only in the event the Company’s average NEEPS over the performance period exceeds the annualized declared dividend per share for the common stock as of the award date (“Dividend Related Earnings”). If the Dividend Related Earnings metric is not met, the units and related dividend equivalents are forfeited. If the Company meets the Dividend Related Earnings metric, the actual number of units that vest is determined by the Committee based on the factors described below.

The number of 2023 PCSUs that vest is determined based on the average NEEPS and TSR results over fiscal years 2023-2025. These metrics are weighted at 25% average NEEPS and 75% TSR. These metrics may be achieved at threshold, target or high-performance levels, as evaluated by the Committee.

Performance under the NEEPS metric is measured by calculating the three-year average of the Company’s NEEPS. In the first year of the performance period, NEEPS was $4.06 on a non-diluted basis. NEEPS for fiscal years 2024 and 2025 will be added to the 2023 NEEPS amount for purposes of calculating the three-year average NEEPS to determine if performance at any level has been achieved.

The level of achievement with respect to the TSR metric for the 2023 PCSUs is measured based on Spire’s rank among

(2) The Committee and management believe that excluding these items provides a useful representation of the economic impact of actual settled transactions and overall results of ongoing operations. These internal non-GAAP operating metrics should not be considered as an alternative to, or more meaningful than, GAAP measures. More information regarding net economic earnings can be found in the 2023 Annual Report on Form 10-K in the Non-GAAP Measures section of Management’s Discussion and Analysis of Financial Condition and Results of Operations.

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     42

its peer group from 2023-2025, determined as a percentile among the group that corresponds with various levels of performance as reflected below.

	Threshold performance	Target performance	High performance
Total shareholder return	25th percentile	50th percentile	100th percentile

With respect to each of the two metrics that determine the number of PCSUs to vest, the “threshold” performance level produces vesting of 50% of the target level of stock units. The “target” performance level produces vesting of 100% of the target level of stock units, and the “high” performance level produces vesting of 200% of the target level of stock units.

Dividend equivalents on PCSUs accrue throughout the performance period and will only be paid to the participants in proportion to the number of shares actually earned at vesting. No interest is paid on the accrued dividend equivalents.

Grants that vested in 2023

On November 12, 2020, the Board authorized the grant of TBRSs and PCSUs to 24 current officers, including all NEOs. The grants were made on November 23, 2020. These awards vested on November 23, 2023.

The PCSUs were granted for the performance period of fiscal years 2021-2023. The vesting of those awards was based upon the three-year average NEEPS metric and the three-year relative TSR metric determined using the peer group in place at the time of the grant, with each of these metrics being weighted at 50%. Additional information about the peer group can be found herein at pages 46-47. TSR for the Company and peer group was calculated as follows:

Total share value at the end of the performance period is calculated as the average share price for the last 20 trading days of the performance period ending September 30, 2023, plus the value of reinvested dividends. Average share price immediately prior to the grant is calculated using the average share price for the last 20 trading days immediately prior to September 30, 2020.

In reviewing the Company’s performance over the period and in accordance with the terms of the EIP, the Committee evaluated the NEEPS metric by averaging the NEEPS for each of fiscal years 2021, 2022 and 2023. The metrics and actual performance for the 2020 PCSUs were as follows:

	Weighting	Threshold performance	Target performance	High performance	Actual performance
Total shareholder return Payout percentage	50%	25th percentile 50%	50th percentile 100%	100th percentile 200%	50th percentile 100%
Three-year average NEEPS Payout percentage	50%	$4.09 50%	$4.42 100%	$4.65 200%	$4.27 77%

On November 9, 2023, the Board certified these performance outcomes, resulting in a total of 54,380 PCSUs vesting (representing 89% of target) for the NEOs. A total of 20,440 TBRSs also vested for the NEOs over the last year. The table to the right shows the number of PCSUs and TBRSs that vested for each NEO.

Executive compensation governance

Roles in executive compensation

The Committee implements and administers the Company’s compensation philosophy and engages an independent compensation consultant to provide market reference perspective and to serve as an advisor. The compensation consultant serves at the request of, and reports directly to, the Committee and does not perform other significant services for the Company.

In fiscal year 2023, the Committee continued its retention of Semler Brossy Consulting Group LLC (“Semler Brossy”) to serve as its consultant. Semler Brossy is an independent firm, providing executive compensation consulting services to the Committee. Semler Brossy reports to the Committee and attends all Committee meetings either in person or by telephone.

The Committee determined that the compensation consultant is independent, and its work has not raised any conflicts of interest.

While the Committee receives advice on executive compensation from its compensation consultant, the Committee and the Board retain all decision-making authority to ensure the decisions reflect the Company’s pay-for-performance philosophy.

The table below outlines the roles and responsibilities of the various parties in determining and deciding executive compensation.

Compensation and human resources committee actions in 2023

The Committee’s review of the Company’s executive pay practices has continued to improve the integrity of our pay-for-performance philosophy, align the interests of our executive officers and shareholders, and strengthen our governance commitment. In 2023, the Committee:

• Reviewed the Company’s competitive pay ranges relative to market;

• Reviewed the Company’s diversity, equity and inclusion initiatives with respect to historical data and discussed progress made during the year;

• Reviewed and discussed executive compensation trends including issues related to pay practices and incentive plans;

• Reviewed the annual and long-term incentive designs and approved metrics of each AIP plan and the EIP plan relative to the corporate financial and non-financial metrics;

• Reviewed and approved updates to the Spire Marketing annual incentive plan;

• Continued to utilize Willis Towers Watson Energy Services Executive Compensation Survey (“WTW Survey”) as the primary market reference to assist the Committee in making its compensation decisions for the executive officers;

• Reviewed tally sheets for the executive officers;

• Reviewed the peer group used to evaluate relative TSR for the PCSUs and decided to maintain consistent peer designation process;

• Reviewed and approved corporate goals for the annual and long-term incentive plans;

• Reviewed and certified performance results for the annual and long-term incentive plans;

• Continued the practice of awarding EIP grants to executives based on fixed value for each position, with validation of the grant levels from competitive market data;

• Conducted an annual compensation risk assessment to evaluate the extent to which the Company’s compensation policies and practices could exacerbate enterprise risks or encourage excessive risk-taking behavior in a manner that would adversely impact the business;

• Further discussed NEO and CEO succession planning, and engaged a third party to conduct certain executive leadership assessments;

• Upon the current CEO’s announcement of retirement, initiated an extensive internal and external search utilizing a national search firm to select a new CEO effective October 1, 2023;

• Reviewed and approved the use of executive talent profiles in the succession planning process as well as individual development activities; and

• Reviewed and discussed the Company’s compensation discussion and analysis for the proxy statement.

Spire’s use of comparator data

Spire uses comparator data in its compensation process in multiple ways. Comparator data is used for evaluating and determining executive compensation levels, and a peer group that is reviewed and approved annually is used for purposes of the relative TSR metric under the EIP. The rationale for the use of this comparator data is described below.

Type of comparator data	How we use it
Willis Towers Watson Energy Services Executive Compensation Survey	Primary data source for executive compensation decisions
Secondary peer group data	Secondary data source to gauge affordability and the aggregate positioning of executive officer compensation
TSR peer group	Approved annually by the compensation and human resources committee and used to evaluate the relative TSR metric for vesting of PCSUs

Competitive market compensation analysis

Each year, the Committee evaluates certain comparator data when determining executive compensation levels to help ensure that compensation opportunities being delivered to our executive officers are competitive within the industry markets in which the Company competes for talent. Although the Committee reviews the data to see how the Company’s executive compensation levels compare to the median range of the Company’s comparator peer data set, decisions are not guided solely by such data, as the Committee’s focus is to make compensation decisions uniquely appropriate for the Company and the individual executive officer.

To assist the Committee in its annual market review of executive officer compensation, the independent compensation consultant prepares an analysis of the market competitiveness of compensation for each executive officer. The independent compensation consultant’s analysis includes a combination of survey and publicly available peer company pay information to establish competitive market rates for base salary and annual and long-term incentives for the executive officer positions. This allows the Committee to ensure its competitive market data is robust, reliable and objective on an ongoing basis.

Spire Inc.  |  2023 Proxy Statement     45

In making compensation decisions, the Committee uses primary and secondary comparator data sets. The primary comparator data set is the WTW Survey, which is a proprietary third-party survey that included responses from 127 companies for the 2022 report. The specific identity of respondents for any given position is not provided to the Company. Because of the large variance in size among participating companies within the survey, the independent compensation consultant conducts analyses, including regression, to adjust the compensation data for differences in revenue scope. These adjustments are necessary to allow for appropriate size comparisons between our Company and the participating companies in the survey. The WTW Survey is used as the primary data source for assessing the individual competitiveness of the executive officers’ pay because it is a more robust sample of data and allows for specific functional matches for each officer.

The secondary comparator data set used in making compensation decisions consists of specific utility companies also utilized in the TSR peer group discussed below. This secondary set of data is used to gauge affordability and the aggregate positioning of executive officer compensation. It also provides a secondary reference point and provides greater detail to the Committee on a company-by-company basis. For fiscal year 2023, these companies included Alliant Energy Corporation, Atmos Energy Corporation, Avista Corporation, Black Hills Corporation, New Jersey Resources Corporation, NiSource Inc., NorthWestern Corporation, Northwest Natural Gas Company, ONE Gas, Inc., and Southwest Gas Corporation.

For each executive, the Committee determines whether target total compensation is sufficient to retain and motivate the executive. If adjustments are needed to create greater alignment with the Company’s compensation philosophy, or to reflect unique circumstances at the Company, the Committee evaluates each component of compensation (base salary, annual incentive and long-term incentive targets) to determine where such adjustments may be required. In addition, the Committee considers other subjective factors in its compensation decisions, such as individual performance, experience, future potential and expertise.

TSR peer group

Annually, the independent compensation consultant, along with the Company’s finance leadership, reviews our peer group members and recommends a group composition that considers industry-appropriateness, business size and changes necessitated due to acquisitions and divestitures. This peer group is used to evaluate the relative TSR metric for vesting of PCSUs. The table on page 47 shows our TSR peer group for fiscal year 2023, as well as a comparison of peer group members for fiscal years 2020 to 2023.

In the TSR peer groups table, the text in orange signifies companies that have been added to the peer group each year, and the asterisks and notes in purple indicate companies that have been removed from the peer group each year. These changes to the peer group are taken into account by the Committee at the time of vesting. For fiscal year 2023, the peer group includes the public companies that participated in the 2022 WTW Survey and have annual revenues of $1 billion to $6 billion, as well as any legacy peer group companies that did not participate in the 2022 WTW Survey. The Committee believes this peer group is an appropriate range of companies against which the Company’s success can be accurately measured.

Spire Inc.  |  2023 Proxy Statement     47

Severance and change in control

The Company believes it is important to provide officers certain compensation in the event of a termination after a change in control, particularly since it does not enter into employment agreements. In addition to the payments described below, the annual and long-term incentive benefits payable to the NEOs upon termination with or without a change in control are described in the “Potential payments upon termination or change in control” section later in this proxy statement.

Executive Severance Plan

Ms. Sitherwood and Mr. Lindsey participate in the Company’s Executive Severance Plan. The severance benefits described herein reflect their roles on September 30, 2023. The Executive Severance Plan provides for a severance benefit if a participant’s employment is terminated by the Company without cause or by the participant for good reason (such terms being defined in the plan). No payment will be made in connection with a termination of employment due to a participant’s death or disability.

The severance benefit is a lump-sum payment equal to the participant’s applicable percentage (200% for Ms. Sitherwood and 100% for Mr. Lindsey) of the participant’s base salary, plus a cash payment equal to the estimated cost of continued medical, dental and vision benefits for a period of 24 months for Ms. Sitherwood and 12 months for Mr. Lindsey.

In the event of a qualifying termination following a change in control, the severance benefit will be a lump-sum payment equal to the participant’s applicable percentage (300% for Ms. Sitherwood and 200% for Mr. Lindsey) of the participant’s base salary plus the participant’s AIP target, plus a cash payment equal to the estimated cost of continued medical, dental and vision benefits for a period of 36 months for Ms. Sitherwood and 24 months for Mr. Lindsey.

The plan defines a change in control as (i) one or more persons acquiring 30% or more of the Company’s outstanding shares; (ii) replacement of a majority of the Board by individuals whose nominations were not approved by a majority of the Board; (iii) consummation of a reorganization, merger or consolidation that results in the Company’s shareholders no longer owning more than 50% of the voting power of the surviving entity’s outstanding securities; or (iv) a liquidation or dissolution of the Company, or a sale of at least 80% of the Company’s assets.

A participant must sign a Confidentiality, Non-Disparagement, Non-Competition and Non-Solicitation Agreement and must execute a release in order to receive a payment under the Executive Severance Plan.

Management Continuity Protection Plan

The Management Continuity Protection Plan (“MCPP”) was adopted in 1991 and was most recently restated in 2005. Effective January 1, 2015, no new participants will enter the MCPP.

Of the NEOs, Messrs. Rasche and Geiselhart were covered by the MCPP at fiscal year-end. Mr. Darrell was covered by the MCPP until he turned age 65. He was not covered under any severance or change in control agreement at fiscal year-end. The MCPP provides for the payment of benefits to officers on certain termination events after a change in control, which is defined as occurring when a person acquires more than 50% of the voting power of securities of the Company or if a person acquires between 30% and 50% of the voting power and the Board determines that a de facto change in control has occurred.

The MCPP provides for a lump-sum payment in an amount equal to the average W-2 compensation paid to a participant for the five-year period immediately preceding cessation of employment, multiplied by 2.99 for an executive vice president or 2.00 for the other officers.

The MCPP does not provide benefit payments to those participants who have reached normal retirement age of 65 and provides no benefits if the officer is terminated for cause. The MCPP limits the amount of the benefit payable to an amount equal to the participant’s average monthly compensation for the five-year period immediately preceding the cessation of employment multiplied by the number of months until the date the participant would reach normal retirement age of 65.

If, after a change in control, a participant in the MCPP is terminated other than for cause, resigns or retires within 54 months in the case of any executive vice president, or within 42 months in the case of all other officers, then the participant is entitled to the lump-sum amount described above. However, the amount is reduced for each month the participant remains employed by the Company starting with the seventh month after the change in control. The amount of the reduction is 1/48 per month for an executive vice president and 1/36 per month for all other officers.

Other Company-provided benefits

The Company believes retirement, health and welfare benefits serve an important role in the total compensation and benefits package offered to employees to assist in attracting and retaining key talent. The Company provides both Company-paid and voluntary health and welfare programs. The programs are reviewed periodically pursuant to the Company’s intent to be competitive within the industry in terms of total compensation.

Retirement plans

The Company offers its employees a defined contribution 401(k) plan that provides a Company match for all employees, including the NEOs. All the NEOs participated in the Spire Employee Savings Plan in fiscal year 2023.

The NEOs also participate in a qualified defined benefit retirement plan sponsored by Spire Missouri Inc. for eligible employees. Spire Missouri Inc. also provides NEOs with non-qualified supplemental retirement plan benefits. More details relative to these plans are included in the “Pension plan compensation” section later in this proxy statement.

Life insurance

The Company provides a life insurance benefit for Ms. Sitherwood in an amount equal to $500,000 while employed by the Company, and the Company provides a life insurance benefit for Messrs. Rasche, Lindsey, Darrell and Geiselhart equal to 200% of base salary, subject to a maximum of $1,500,000 while employed by the Company. Following retirement, the Company provides a life insurance benefit equal to 50% of the employee’s active life insurance benefit, subject to a maximum of $250,000, if under age 70; or 25% of the employee’s active life insurance benefit, subject to a maximum of $125,000, if age 70 or older. The costs for this coverage are included in the “All other compensation” column of the “Summary compensation table.”

Deferred income plans

Since 1986, the Company has offered its directors, officers and certain key employees the opportunity to defer income under deferred income plans. More details on the plans are provided in the “Non-qualified deferred compensation” section later in this proxy statement.

Perquisites

As a matter of business philosophy, the Company provides limited perquisites or personal benefits to executive officers (including the CEO). These limited perquisites include spousal travel to industry associations that encourage spousal attendance, and executive financial and tax planning. When an executive must relocate, perquisites may also include the payment of relocation expenses as well as the associated tax obligations.

Tax implications of the Committee’s compensation decisions

Section 162(m) of the Internal Revenue Code (“Code”) generally limits tax deductibility of compensation paid by a public company to its chief executive officer and certain other current and former executive officers in any year to $1 million in the year compensation becomes taxable to the executive.

The Committee has historically considered Section 162(m) in the design of incentive plans to preserve the corporate tax deductibility of compensation. However, in light of changes made to Section 162(m) for tax years beginning after December 31, 2017, compensation over $1 million paid to any NEO will be subject to a tax deduction disallowance under Section 162(m). The Committee recognizes that factors other than tax deductibility should be considered in determining the forms and levels of executive compensation most appropriate and in the best interests of the Company and its shareholders. Annually, the Committee reviews all compensation programs and payments, including the tax impact on the Company.

Spire Inc.  |  2023 Proxy Statement     49

Accounting information

The Company accounts for equity incentive grants under FASB ASC Topic 718. The fair value of stock-based awards is estimated using the closing price of the Company’s common stock on the grant date or, for those with the total shareholder return modifier, using a Monte Carlo simulation model that assesses probabilities of various outcomes of market conditions. Each year, an independent third party runs the Monte Carlo simulation, which is subject to the audit procedures of the Company’s independent registered public accounting firm. During fiscal year 2023, the Company did not make any modifications to equity grants that resulted in a remeasurement of expense under the accounting rules.

Compensation and human resources committee report

The Committee has reviewed and discussed with Company management the CD&A section included in this proxy statement. Based on this review and discussion, the Committee recommended to the Board (and the Board has approved) that this CD&A be included in this proxy statement and incorporated by reference in the 2023 Annual Report on Form 10-K.

Grants of plan-based awards

The plans under which grants in the table below were made are generally described in the CD&A in the “Annual incentive compensation” and “Long-term incentive compensation” sections.

Under the AIP, performance metrics and potential targets for awards are typically approved in November, with the determinations of earned award amounts made the following November, based upon corporate, safety and individual performance in the most recently completed fiscal year.

Equity awards are generally considered for grant in November each year, with the grant date occurring after the November Committee and Board meetings. Under the EIP, the Committee may grant performance-based awards, stock appreciation rights, stock options, shares of restricted stock or restricted stock units.

Pension plan compensation

The NEOs participate in the Spire Missouri Employees’ Retirement Plan, a qualified defined benefit plan sponsored by Spire Missouri Inc.

Grandfathered pension benefit

Effective January 1, 2009, Spire Missouri Inc. amended its plan to change the way benefits are calculated. Prior to that date, the plan provided benefits based on a final pay formula that used a participant’s years of credited service and average final compensation. The average final compensation is the highest consecutive three-year average of the final 10 years of employment. Participants’ years of credited service under the plan were frozen as of December 31, 2008; however, the average final pay was not frozen and will continue to be based on the highest three-year average in the final 10 years of employment until December 31, 2023, at which time the average final pay will also be frozen. Benefits under the plan formula in effect prior to January 1, 2009 are referred to as “grandfathered benefits.” With respect to annual incentive compensation paid on or after January 1, 2013, average final compensation will exclude such incentive compensation for purposes of the grandfathered benefit. Of the NEOs, only Messrs. Darrell and Geiselhart have grandfathered benefits.

While normal retirement age under the plan is age 65, participants may retire at age 60 with 10 or more years of service without reduction of the grandfathered benefit for early retirement. As Messrs. Darrell and Geiselhart are both age 60 or older, immediate retirement is assumed in calculating their grandfathered benefits.

Spire Inc.  |  2023 Proxy Statement     55

Cash balance benefit

On and after January 1, 2009, the plan uses a cash balance formula that provides: (i) a cash balance credit between 4 to 10% of compensation (base salary and annual incentive compensation) depending on the participant’s age, and (ii) interest credits using a rate equal to an average of corporate bond rates published by the Internal Revenue Service. Benefits under the plan formula in effect on and after January 1, 2009 are referred to as “current benefits.” The cash balance credit and interest credit are applied as of December 31 of each year, on an average monthly basis, with interest compounded monthly. For calendar year 2023, cash balance credits were as follows:

Sitherwood	10	%
Rasche	10
Lindsey	9
Darrell	10
Geiselhart	10

The early retirement amount of the current benefits will be the amount credited in the participant’s cash balance account in the case of a lump-sum payment. If an annuity is taken at early retirement, the benefit will be the actuarial equivalent of the lump-sum amount.

Supplemental retirement benefits

The Code generally places a limit on the amount of the annual pension that can be paid from a qualified defined benefit plan as well as on the amount of annual earnings that can be used to calculate a pension benefit. Since 1977, Spire Missouri Inc. has maintained a Supplemental Retirement Benefit Plan, a non-qualified plan that covers pension benefits that accrued through December 31, 2004, and that pays eligible employees the difference between the amount payable under the qualified plan and the amount they would have received without the limits on the qualified plan or without any deferred income plan contributions. Spire Missouri Inc. adopted the Supplemental Retirement Benefit Plan II to comply with Code Section 409A, which covers grandfathered pension benefits accrued on and after January 1, 2005. It also adopted the Cash Balance Supplemental Retirement Benefit Plan, which covers cash balance benefits accruing on and after January 1, 2009.

Please note the following relating to the benefits shown in the table below:

•	the Supplemental Retirement Benefit Plans are unfunded and subject to reduction or forfeiture in the event of the Company’s bankruptcy;
•	the years of credited service in the table are the same as the executives’ years of actual service as of December 31, 2008, when years of service were frozen for all participants;
•	the compensation used to determine current and grandfathered benefits under the plans include the amounts in the “Salary” column and the amount attributable to payments under the AIP in the “Non-equity incentive plan compensation” column (for current benefits only after January 1, 2013) in the “Summary compensation table;” and
•	executives at the Company are subject to mandatory retirement at age 65 unless the Board of Directors of Spire Missouri Inc. asks them to continue working past that age.
The pension benefits in the table below were calculated using:
•	the September 30, 2023 measurement date;
•	the same assumptions as described in Note 13, Pension Plans and Other Post-Retirement Benefits, of the consolidated financial statements in the 2023 Annual Report on Form 10-K for the fiscal year ended September 30, 2023, except retirement at the greater of 60 or the executive’s actual age as noted above was used for the grandfathered benefit and, as required, no income growth assumption nor any forfeiture assumption was used;
•	for the grandfathered benefit, the greater of:

– years of service, multiplied by the sum of 1.7% of Social Security covered compensation (a 35-year average of Social Security maximum wage bases) plus 2.0% of the highest average normal compensation during a 36-month period in the 10 years prior to the measurement date in excess of Social Security covered compensation; and

– the highest average normal compensation during a 36-month period in the 10 years prior to the measurement date, multiplied by (i) years of service, and (ii) the benefit factor of 2.1%, less the executive’s estimated Social Security benefit multiplied by 1.25% for each year of service up to a maximum of 40 years.

• the assumption of a 90% probability that the participant elects a lump-sum equivalent of the monthly annuity amount described above.

Non-qualified deferred compensation

Executives are eligible to participate in the deferred compensation plans offered by the Company.

Spire Deferred Income Plan

The Spire Deferred Income Plan (“Deferred Income Plan”) covers participant deferrals made on and after January 1, 2005, and is intended to comply with Code Section 409A.

Executive deferrals

Effective January 1, 2015, the Deferred Income Plan allowed participants, including the NEOs, to defer up to 50% of annual salary, and up to 90% of AIP compensation. Prior to 2015, participants could defer up to 15% of annual salary. For plan years beginning on and after January 1, 2020, participants, including the NEOs, may defer up to 80% of annual salary.

Effective January 1, 2019, the Deferred Income Plan was amended to permit the deferral of up to 100% of equity compensation. In fiscal year 2019, participants could elect to defer PCSUs granted on December 1, 2017 and November 14, 2018. Beginning in fiscal year 2020, participants may elect to defer current grants of PCSUs and TBRSs. Any deferred equity will be distributed in cash, rather than shares.

Plan investments

Effective January 1, 2016, the Deferred Income Plan provides participant investment options that mirror returns in certain 401(k) plan investment funds and Company stock. Effective January 1, 2021, participants were offered an increased menu of diversified investment options. Participants may also elect an annual fixed interest rate based on Moody’s Corporate Bond Rate not to exceed 120% of the Applicable Federal Rate.

Deferrals made prior to 2016 earn investment income equal to the greater of:

• the Moody’s Corporate Bond Rate, plus an interest credit ranging from 1 to 3% depending on the age of the participant at the start of the specific plan year, or

• a guaranteed interest rate based on the age of the participant at the start of the specific plan year.

Deferrals of equity grants cannot be diversified into other investments for six months after the grants vest. Dividends paid on deferred equity are invested in any fund instructed by the participant other than the Company stock fund.

Plan benefits

The Deferred Income Plan provides retirement benefits payable in annual installments over a 15-year period based on the deferred account balance as of the date of retirement. Effective January 1, 2018, participants can elect for new deferrals to be distributed in a lump sum or in installments over two to 15 years.

In the event of any other termination of employment prior to age 55, the executive will receive the deferred account balance reduced by any additional interest credits payable in a lump sum.

Spire Inc.  |  2023 Proxy Statement     57

The Deferred Income Plan provides:

• death and disability benefits payable in a lump sum

• a lump-sum payment if the participant is terminated within two years of a change in control.

For participant deferrals made in or after calendar year 2016, the disability and change in control termination benefits are equal to the deferred account balance at the date of disability or termination.

For participant deferrals made in or after calendar year 2016, the death benefits are equal to the deferred account balance plus participant deferrals projected from the date of death to the end of the plan year in which death occurred.

For participant deferrals made prior to calendar year 2016, the disability deferred account balance is credited with investment income through the end of the plan year in which disability occurs.

The benefits payable for participant deferrals prior to calendar year 2016 upon death, disability and change in control termination are equal to the greater of:

• the present value of the deferred account balance projected through age 65 or

• the deferred account balance accumulated through the respective termination date.

Laclede Gas Company Deferred Income Plan II

The Laclede Gas Company Deferred Income Plan II (“Deferred Income Plan II”) covers participant deferrals prior to January 1, 2005. Only Mr. Darrell has benefits under the Deferred Income Plan II.

The Deferred Income Plan II provides similar benefits as the Deferred Income Plan with the following exceptions:

• death and disability benefits are payable in 15 annual installments, and

• retirement benefits are payable in 15 annual installments; benefits continue for the participant’s lifetime following retirement at age 65 or later (at least 15 annual installments).

The amounts in the table below include contributions by the executive and investment earnings under both deferred compensation plans.

Potential payments upon termination or change in control

This section describes the potential payments and benefits to which the NEOs would have been entitled upon termination of employment, including termination of employment following a change in control, as if such termination had occurred on the last trading day of our fiscal year (September 29, 2023) using the New York Stock Exchange closing price of $56.58 per share of the Company’s stock on that date. The discussion does not include payments and benefits to the extent they are generally provided on a non-discriminatory basis to salaried employees upon termination of employment. The following table sets forth the potential payments to the NEOs upon the termination of their employment with the Company, including a termination of employment following a change in control. The table does not include retirement plan benefits payable to the executives shown in the “Pension benefits table.”

(1)	Ms. Sitherwood and Mr. Lindsey are participants in the Executive Severance Plan, which provides for a cash payment in the event of an involuntary termination, whether by the Company without cause, or by the executive for good reason, the amount of which is increased if such involuntary termination occurs within 24 months after a change in control. In the event of involuntary termination, Ms. Sitherwood’s cash payment would be based on a multiple of two times annual base salary. Mr. Lindsey’s cash payment would be based on a multiple of one times annual base salary. In the event of involuntary termination within two years following a change in control, Ms. Sitherwood’s cash payment would be based on a multiple of three times annual base salary plus target AIP. Mr. Lindsey’s cash payment would be based on a multiple of two times annual base salary plus target AIP.
	Messrs. Rasche and Geiselhart are covered by the Management Continuity Protection Plan (“MCPP”). The potential payments to these officers are limited to termination within 54 months for Mr. Rasche and 42 months for Mr. Geiselhart after a change in control. This cash payment for Mr. Rasche is equal to 2.99 times average annual W-2 compensation, and this cash payment for Mr. Geiselhart is equal to 2.0 times average annual W-2 compensation. Mr. Darrell was no longer covered by the MCPP after he turned age 65 in November 2022.
(2)	Upon a change in control, any awards under the AIP are deemed earned at a prorated target based on the number of completed days in the fiscal year prior to the change in control. This payment takes place whether or not a termination occurs. The AIP’s definition of change in control mirrors the definition in the Executive Severance Plan.
	If a participant’s employment ceases due to termination without cause or by death, disability or retirement, the participant is eligible to earn a prorated award based upon Company performance and the participant’s achievement of individual metrics.

Spire Inc.  |  2023 Proxy Statement     59

(3)	Participants, including the NEOs, have outstanding PCSUs and TBRSs under the EIP. The EIP uses the same definition of change in control that is used in the AIP and the Executive Severance Plan.
	PCSUs. These awards generally provide for vesting of stock units on the third anniversary of the grant date that falls after the end of the performance period, to the extent the Committee determines and certifies that the performance criteria have been met or exceeded. A participant forfeits all non-vested awards upon the participant’s termination of employment for cause.
	If during the performance period a participant dies or leaves the Company due to retirement or disability, the participant remains eligible to earn a prorated award based on the number of full months as a participant during the performance period, as the Committee may determine, if the performance contingency is satisfied.
	In the event of a change in control, any outstanding awards shall be deemed earned and vested at a prorated target, based on the number of months completed in the performance period at the time of the change in control, if the award is not assumed or replaced with a comparable award by the successor or surviving entity. If the successor or surviving entity does not assume or replace the award, the award will trigger a benefit at a prorated target based on the number of full months as a participant if the participant is involuntarily terminated without cause within two years of the change in control. Dividend equivalents on PCSUs are accrued throughout the performance period and paid to the participant in proportion to the amount of shares actually earned at vesting, up to the amount of dividends that would have been paid on the target number of shares. In the event of a change in control, accrued dividend equivalents would be paid on the same prorated basis as mentioned above. The same amounts would be payable in the event of a participant’s death, retirement or termination of employment due to disability if the target level of performance is achieved. As a result of being retirement-eligible at the time of any termination, PCSU grants would vest on a pro-rata basis for the following individuals, at a value of:

Sitherwood	$	3,247,598	*
Rasche		630,301	*
Lindsey		934,105	*
Darrell		493,818	*
Geiselhart		466,440	*

	*These amounts are included in the “Equity grants” column.
	TBRSs. These shares generally provide for vesting on the third anniversary of the grant date. A participant forfeits all non-vested shares upon the participant’s termination of employment for any reason prior to vesting, other than as a result of a change in control or mandatory retirement requirements. Mr. Darrell was subject to mandatory retirement requirements during fiscal year 2023, but his employment was extended by 12 months, and he retired on December 1, 2023.
	If a participant’s employment is terminated by the Company without cause within two years following a change in control, the shares become vested on the earlier of the vesting date or the date of the change in control. If a participant’s employment is terminated due to mandatory retirement requirements, the shares become vested based on the number of full months from the award date to the participant’s retirement.
(4)	Under the terms of the deferred income plans, if a participant’s employment is terminated within two years of a change in control, the participant will receive a lump-sum payment equal to the greater of (i) the present value of the account balance projected through age 65 using a guaranteed minimum rate of return, or (ii) the actual account balance accumulated through the termination date. However, for deferrals made on and after January 1, 2015, the lump-sum payment would be equal to the participant’s account balance plus the present value of employer contributions and earnings credits that would have been made or earned on such account balance through age 65.
	Upon retirement, the participant will receive the participant’s account balance in 15 installments unless the participant elected a lump sum for deferrals made on and after January 1, 2005, or elected a lump sum or different number of installments for deferrals on or after January 1, 2018. In the event of death or disability, a participant or the participant’s beneficiary will receive the participant’s account balance plus the projected earnings that would have been payable if the participant had retired at age 65.
	Upon any other termination of employment, the participant will receive all deferred amounts plus interest accrued at the Moody’s rate applicable to each plan year.
	The amounts reflected in this table are the amounts each executive would receive if the executive terminated on September 29, 2023. The account balance as of the end of fiscal year 2023 is reflected in the “Non-qualified deferred compensation table” above.
(5)	The Executive Severance Plan provides that the Company will provide a cash payment equal to a certain number of months of continued medical, dental and vision coverage. In the event of involuntary termination, absent a change in control, Ms. Sitherwood would receive a cash payment equal to 24 months of continued medical, dental and vision benefits, and Mr. Lindsey would receive a cash payment equal to 12 months of continued medical, dental and vision benefits. In the event of involuntary termination within two years following a change in control, Ms. Sitherwood would receive a cash payment equal to 36 months of continued medical, dental and vision benefits, and Mr. Lindsey would receive a cash payment equal to 24 months of continued medical, dental and vision benefits. The table reflects these cash payments under the “Health benefits” column. The MCPP, which governs the severance arrangements for Messrs. Rasche and Geiselhart, does not provide for Company-paid health benefits or any cash equivalent upon termination.
(6)	Code Section 280G provides guidelines that govern payments triggered by a change in control, known as “parachute payments.” If such payments exceed three times the five-year average annual compensation for certain individuals, the payments may trigger adverse tax consequences and excise taxes. The Company does not provide any gross-up payments for such adverse tax consequences or excise taxes under any of the arrangements. The Executive Severance Plan provides for a “best of net” calculation whereby the reduction in the severance calculation is determined to be the better of a reduction of the calculated amount to the amount permissible under Code Section 280G or the cost to the executive of paying the 20% excise tax on the calculated severance payment. Based on the exemption under Code Section 280G for severance pay that is tied to a non-competition agreement, we believe Ms. Sitherwood’s severance payment and other change in control benefits would not exceed the limits under Code Section 280G. We also believe Mr. Lindsey’s severance payment and other change in control benefits would not exceed the limits under Code Section 280G.
	The MCPP provides for the reduction of the calculated severance value to the amount permissible under Code Section 280G. This amount represents the amount the severance payment to Mr. Rasche would be reduced. We believe no reduction would be required for Mr. Geiselhart.

CEO pay ratio

Under Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to provide the ratio of the annual total compensation of Ms. Sitherwood, our former president and chief executive officer, to the annual total compensation of the median employee of the Company.

For fiscal year 2023, the annual total compensation of the median employee of the Company and its subsidiaries (other than the president and chief executive officer) was $98,084. Ms. Sitherwood’s total annual compensation for fiscal year 2023 was $5,213,657. Based on this information, the ratio of the compensation of the chief executive officer to the annual total compensation of the median employee was estimated to be 53 to 1.

To identify the median employee, and to determine the total annual compensation of such employee, we used the following methodology. We identified our median employee as of the end of the fiscal year, September 30, 2023, based on our entire workforce of 3,589 employees, using base pay, plus annual and long-term incentive compensation, for the period of October 1, 2022 through September 30, 2023. Once the median employee was identified, we then determined the median employee’s annual total compensation for fiscal year 2023 using the Summary Compensation Table methodology set out in Item 402(c)(2)(x) of Regulation S-K. With respect to the annual total compensation of Ms. Sitherwood, we used the amount reported in the “Total” column of the “Summary compensation table.”

SEC rules for identifying the median employee and calculating the pay ratio allow companies to apply various methodologies and various assumptions and, as a result, the pay ratio reported by the Company may not be comparable to the pay ratio reported by other companies.

The peer group TSR in this table utilizes the S&P 500 Utilities Index (“S&P Index”), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in the 2023 Annual Report on Form 10-K. The comparison assumes $100 was invested for the period starting September 30, 2020, through the end of the listed year in the Company and in the S&P Index, respectively. All dollar values assume reinvestment of the pre-tax value of dividends paid by companies, where applicable, included in the S&P Index. Historical stock performance is not necessarily indicative of future stock performance.

(4)

Net economic earnings per share performance summarized above is based on our average basic net economic earnings per share over a period of three years. Net economic earnings exclude from net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisitions, divestiture and restructuring activities, and the largely non-cash impacts of impairments and other non-recurring or unusual items, such as certain regulatory, legislative or GAAP standard-setting actions.

Relationship between CAP and performance metrics

The following charts present a graphical comparison of compensation actually paid to the PEO and the average compensation actually paid to the non-PEO NEOs set forth in the “Pay versus performance table” above, as compared against the following Company performance measures: (1) total shareholder return (TSR); (2) net income; and (3) net economic earnings per phare (NEEPS).

The first graph compares the Company’s TSR and peer group TSR, assumes an initial investment of $100 on September 30, 2020, assumes all dividends were reinvested and depicts performance at the end of each applicable year. The most important annual financial measure linking pay to performance for fiscal year 2023 is the Company’s NEEPS.

Proposal 3: Ratification of appointment of independent registered public accountant

The Board of Directors, upon recommendation of its audit committee, recommends that you ratify the appointment of Deloitte as independent registered public accountant, to audit the books, records and accounts of Spire Inc. and its subsidiaries for the fiscal year ending September 30, 2024. A representative of Deloitte will be present at the annual meeting, will have an opportunity to make a statement if he or she desires to do so, and will be available to respond to appropriate questions.

Your Board of Directors recommends a vote “FOR” ratification of the appointment of Deloitte & Touche LLP as independent registered public accountant.

Audit committee report

The audit committee of the Board of Directors is composed of six directors who are independent as required by and in compliance with the applicable listing standards of the New York Stock Exchange and the rules of the SEC. The names of the committee members as of the date of this proxy statement appear at the end of this report. The committee operates under a written charter.

The primary function of the audit committee is oversight. Management is responsible for the preparation, presentation and integrity of the Company’s financial statements. Management is also responsible for maintaining appropriate accounting and financial reporting practices and policies; for establishing internal controls and procedures designed to provide reasonable assurance that the Company is in compliance with accounting standards and applicable laws and regulations; and for assessing the effectiveness of the Company’s internal control over financial reporting.

Deloitte, the Company’s independent registered public accounting firm, is responsible for planning and performing an independent audit of the financial statements in accordance with the standards of the PCAOB and to issue reports expressing an opinion, based on its audit (i) as to the conformity of the audited financial statements with generally accepted accounting principles and (ii) on the effectiveness of the Company’s internal control over financial reporting. The committee is responsible for the appointment, compensation and oversight of Deloitte.

In fulfilling its oversight responsibilities, the committee reviewed and discussed the audited financial statements in the 2023 Annual Report on Form 10-K with management and Deloitte, which included a discussion of the critical accounting policies and practices used by the Company. The committee also discussed with Deloitte the matters required to be discussed under the applicable PCAOB standards.

Deloitte has provided the committee with the written disclosures and letter required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the audit committee concerning independence, and the committee has discussed with Deloitte its independence.

Based on the reviews and discussions referred to above, the committee recommended to the Board of Directors that the audited financial statements referred to above be included in the 2023 Annual Report on Form 10-K.

Fees of independent registered public accountant

The following table displays the aggregate fees for professional audit services for the audit of the financial statements for the fiscal years ended September 30, 2023 and 2022, and fees incurred for other services performed during those periods by the Company’s independent registered public accounting firm, Deloitte.

	2023	2022
Audit fees	$2,612,000	$2,500,000
Audit-related fees(1)	330,000	243,000
Tax fees(2)	41,462	37,654
All other fees(3)	1,895	1,895
Total	$2,985,357	$2,782,549

(1)	Audit-related fees consisted of comfort letters for debt and equity raises, consents for registration statements and review of acquisition accounting.
(2)	Tax fees consisted primarily of assistance with tax planning, compliance and reporting.
(3)	All other fees consisted of an annual subscription for the accounting technical library.

Audit fees for fiscal year 2023 were higher than 2022 as the result of inflation as well as increased capital market activity. The audit committee pre-approved all the fees for fiscal years 2023 and 2022. The Policy Regarding the Approval of Independent Registered Public Accountant Provision of Audit and Non-Audit Services is described earlier in this proxy statement.

Other matters

About the annual shareholder meeting

This proxy statement is furnished to solicit proxies by the Board of Directors of Spire for use at the annual meeting of its shareholders to be held at 8:30 a.m., Central Standard Time, on Thursday, January 25, 2024, and at any adjournment or postponement of the meeting.

The meeting will be held via live webcast through the link set forth in the Notice of Annual Meeting of Shareholders included in this proxy statement. To attend and vote, you will need the 16-digit control number included in your Notice of Internet Availability of Proxy Materials, on your proxy card or on the instructions that accompany your proxy materials.

This proxy statement is first being made available to shareholders with the 2023 Annual Report on Form 10-K on or about December 13, 2023. The Company’s principal business office is located at 700 Market Street, St. Louis, MO 63101.

Questions and answers about the annual meeting

Who is soliciting my vote?

The Board of Directors of Spire is soliciting your vote for the Company’s annual meeting of shareholders.

When will the meeting take place?

The annual meeting will be held at 8:30 a.m., Central Standard Time, on Thursday, January 25, 2024. The meeting will be held virtually through the link set forth in the Notice of Annual Meeting of Shareholders included in this proxy statement.

Who is entitled to vote at the annual meeting?

If you owned Spire common stock at the close of business on November 30, 2023, you may attend and vote at the annual meeting.

Why did I receive a notice in the mail regarding the internet availability of proxy materials instead of a paper copy of proxy materials?

Under the “Notice and Access” rules of the SEC, we are permitted to furnish proxy materials, including this proxy statement and the 2023 Annual Report on Form 10-K, to our shareholders by providing a Notice of Internet Availability of Proxy Materials (“Notice”). Most shareholders will not receive printed copies unless they request them. The Notice instructs you as to how you may access proxy materials on the internet and how you may submit your proxy via the internet. If you would like to receive a paper or electronic copy of our proxy materials, you should follow the instructions for requesting such materials in the Notice. Any request to receive proxy materials by mail or electronically will remain in effect until you revoke it.

If more than one shareholder lives in my household and I have elected to receive printed copies of the proxy materials, how can I obtain an extra copy of the proxy materials?

For those shareholders who have elected to receive printed copies of our proxy materials, under the rules of the SEC, we are permitted to deliver a single copy of this proxy statement and our Annual Report on Form 10-K to multiple shareholders that share the same address, unless we have received contrary instructions from any such shareholder. This practice, known as “householding,” is designed to reduce our printing and postage costs. Upon written or oral request, we will mail a separate copy of this proxy statement and our Annual Report on Form 10-K to any shareholder at a shared address to which a single copy of each document was delivered. You may call, toll free, 866-540-7095, or write to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, NY 11717 to request a separate copy.

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     68

Can I vote my shares by filling out and returning the notice?

No, the Notice identifies the items to be voted on at the annual meeting; you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to: (i) vote by internet, (ii) vote by telephone, and (iii) request and return a paper proxy card or voting instruction card.

Why didn’t I receive a notice in the mail regarding the internet availability of proxy materials?

If you previously elected to access proxy materials over the internet, you will not receive a Notice in the mail. You should have received an email with links to the proxy materials and online proxy voting. Also, if you previously requested paper copies of the proxy materials or if applicable regulations required delivery of the proxy materials, you will not receive the Notice.

If you received a paper copy of the proxy materials or the Notice by mail, you can eliminate paper mailings in the future by electing to receive an email that will provide internet links to these documents. Opting to receive future proxy materials online will save us the cost of printing and mailing documents and help us conserve natural resources. Enrollment for electronic delivery is effective until revoked.

Who is a shareholder of record?

You are a shareholder of record if your shares are registered directly in your name with our transfer agent, Computershare. You will receive a Notice or these proxy materials by delivery directly to you. You are entitled to vote your shares by internet, telephone, at the virtual meeting, or, if you have requested printed proxy materials, by completing and returning the enclosed proxy card.

Who is a beneficial owner?

You are a beneficial owner if you hold your stock in a stock brokerage account, or through a bank or other nominee. Your shares are held in “street name” and the Notice or these proxy materials are being sent to you by your broker, bank or nominee, who is considered the shareholder of record. As a beneficial owner, you have the right to direct your broker, bank or nominee on how to vote. You may attend the annual meeting virtually, but you will need to provide a letter or statement from that firm that shows you were a beneficial owner of Spire shares on November 30, 2023. You may not vote these shares virtually at the annual meeting unless you request, complete and deliver a legal proxy from your broker, bank or nominee. If you requested printed proxy materials, your broker, bank or nominee provided a voting instruction card for you to use in directing the broker, bank or nominee on how to vote your shares.

How many shares must be present to hold the annual meeting?

A majority of our issued and outstanding shares entitled to vote at the annual meeting as of the record date must be virtually present or represented by proxy to have a quorum. As of November 30, 2023, there were 53,229,195 shares outstanding. Both abstentions and broker non-votes are counted as present for purposes of determining quorum.

How many votes are required for each item of business?

Election of directors

The election of directors requires the affirmative vote FOR each nominee of a majority of those shares entitled to vote and virtually present at the meeting or represented by proxy. Withheld votes and abstentions will have the effect of votes against the nominee, while broker non-votes will not be considered represented and will have no effect on the outcome.

Advisory approval of the compensation of our named executive officers

This proposal, which is non-binding, requires the affirmative vote of a majority of the shares entitled to vote and virtually present or represented by proxy at the meeting to be approved. Abstentions will have the effect of a vote against the proposal, while broker non-votes will not be counted as votes cast and will have no effect on the outcome.

Spire Inc.  |  2023 Proxy Statement     69

Voting matters

How do I vote?

You may vote on the internet, by telephone, by mail or by virtually attending the annual meeting through the link set forth in the Notice of Annual Meeting of Shareholders included in this proxy statement and voting by ballot. The internet and telephone voting procedures are designed to authenticate that you are a shareholder by use of a control number. The procedures allow you to confirm that your instructions have been properly recorded. If you vote by telephone or internet, you do not need to mail back your proxy card or voting instruction card.

By internet

If you have internet access, you may submit your proxy by following the instructions provided in the Notice, or, if you requested printed proxy materials, by following the instructions provided with your proxy materials and on your proxy card or voting instruction card. On the internet voting site, you can confirm that your instructions have been properly recorded. If you vote on the internet, you can also request electronic delivery of future proxy materials.

By telephone

You can vote by telephone by following the instructions provided in the Notice, or, if you requested printed proxy materials, by following the instructions provided with your proxy materials and on your proxy card or voting instruction card.

By mail

If you elected to receive printed proxy materials by mail, you may choose to vote by mail by marking your proxy card or voting instruction card, dating and signing it, and returning it in the postage-paid envelope provided. Please allow sufficient time for mailing if you decide to vote by mail.

At the annual meeting

This year’s annual meeting will be held entirely online to allow for greater participation. Shareholders may participate in the annual meeting by visiting the following website: www.virtualshareholdermeeting.com/SR2024. To participate in the annual meeting, you will need the 16-digit control number included in your Notice, on your proxy card or on the instructions that accompany your proxy materials.

Shares held in your name as the shareholder of record may be voted electronically during the annual meeting by following the instructions on the screen. However, if your shares are held in the name of a bank, broker or the nominee, you must obtain a legal proxy, executed in your favor, from the holder of record to be able to vote at the annual meeting. You should allow yourself enough time prior to the annual meeting to obtain this proxy from the holder of record.

The shares voted electronically, by telephone or represented by proxy cards received, properly marked, dated, signed and not revoked, will be voted at the annual meeting.

If you hold your shares through a broker, please note that your broker will not be permitted to vote on your behalf for the first two proposals unless you provide instructions as to how to vote your shares. Voting your shares is important to ensure you are represented at the meeting. If you have any questions about the voting process, please contact the broker where you hold your shares.

Can I vote my shares that are held in the Company’s dividend reinvestment and stock purchase plan or any of the Company’s 401(k) plans?

If you participate in the Company’s dividend reinvestment and stock purchase plan or in the Company Stock Fund of the Spire Employee Savings Plan, you are entitled to vote those shares. If you do not give voting instructions for shares owned by you through this plan, none of your shares held in the plan will be voted. To allow sufficient time for voting by the administrator and trustee of the plan, your voting instructions must be received by January 22, 2024.

How can I revoke or change my vote?

You may revoke your proxy at any time before it is voted at the meeting by:

• Sending timely written notice of revocation to the corporate secretary;

• Submitting another timely proxy by telephone, internet or proxy card; or

• Attending the annual meeting and voting your shares. If your shares are held in the name of a bank, broker or other holder of record, you must obtain a proxy executed in your favor from the holder of record to be able to vote at the meeting.

www.SpireEnergy.com Spire Inc.  |  2023 Proxy Statement     70

How many votes do I have?

You are entitled to one vote for each share you owned on November 30, 2023.

What happens if I don’t give specific voting instructions?

Shareholders of record

If you are a shareholder of record and you either indicate you want to vote as recommended by the Board of Directors or you return a signed proxy card but do not indicate how you want to vote, then your shares will be voted in accordance with the recommendations of the Board of Directors on all matters presented in this proxy statement and as the proxy holders may determine in their discretion regarding any other matters properly presented for a vote at the meeting. If you indicate a choice for any matter to be acted upon, the shares will be voted in accordance with your instructions.

Beneficial owners

If you hold shares in street name and do not provide instructions, your shares may constitute “broker non-votes” on certain proposals. Generally, broker non-votes occur on a non-routine proposal where a broker is not permitted to vote on that proposal without instructions from the beneficial owner and instructions are not given. Broker non-votes are considered present at the annual meeting, but not as voting on a matter. Thus, broker non-votes are counted as present for purposes of determining whether there is a quorum but are not counted for purposes of determining whether a matter has been approved. Broker non-votes will not affect the outcome of the votes on the first two proposals. If you do not provide instructions to your broker, under the rules of the New York Stock Exchange, your broker will not be authorized to vote the shares it holds for you with respect to the first two proposals. Your broker has the discretion, however, to vote the shares it holds for you on the ratification of the independent registered public accountant.

Who counts the votes?

We hired Broadridge Financial Solutions as an independent tabulator of votes to ensure confidentiality of the voting process. However, if you write comments on your proxy card, the comments will be shared with us. We also have hired Broadridge Financial Solutions to serve as independent inspector of elections.

Requirements for submission of proxy proposals, nomination of directors and other business

Under the rules of the SEC, shareholder proposals intended to be included in the proxy statement for the annual meeting of shareholders in January 2025 must be received by the corporate secretary of Spire at its principal business office at the address set forth on page 27 of this proxy statement by August 15, 2024.

Also, the procedures to be used by shareholders to recommend nominees to the corporate governance committee are outlined on page 27 of this proxy statement. If a shareholder seeks to nominate a person or make a shareholder proposal from the floor of the annual meeting in January 2025, notice must be received by the corporate secretary at the Company’s principal business offices no later than October 27, 2024, and not before September 27, 2024 (not less than 90 days nor more than 120 days, respectively, prior to January 25, 2025, which is the anniversary date of the 2024 annual meeting). Also, such proposal must be, under law, an appropriate subject for shareholder action to be brought before the meeting and comply with the notice provisions of the Company’s bylaws. However, if next year’s annual meeting is held on a date that is more than 30 days before or after January 25, 2025, the anniversary of the 2024 annual meeting, shareholder proposals that have not been submitted by the deadline for inclusion in the proxy statement and any nominations for director must be received by the close of business on the tenth day following the earlier of the date on which notice of the annual meeting is mailed or the date on which public disclosure of the date of the annual meeting is made. To comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees for next year’s annual meeting must provide timely notice by the same deadline noted in the preceding sentences for the submission of nominations. Such notice must comply with the additional requirements of Rule 14a-19(b) under the Securities Exchange Act of 1934, as amended.

The Chair of the Board may refuse to allow the transaction of any business or to acknowledge the nomination of any person not made in compliance with the procedures set forth in the Company’s bylaws.

Spire Inc.  |  2023 Proxy Statement     71

Proxy solicitation

We will pay the expense of soliciting proxies. Proxies may be solicited on our behalf by officers or employees by email, telephone, fax or special letter. We have hired Morrow Sodali LLC, 333 Ludlow Street, 5^th Floor, South Tower, Stamford, CT 06902, to assist us in the solicitation of proxies for a fee of $8,500, plus reimbursement for out-of-pocket expenses for those services.

Schedule A: Reconciliation of operating income to adjusted operating income

Adjusted operating income is a non-GAAP financial measure used by the Board and management to measure corporate performance for purposes of the Annual Incentive Plan. Adjusted operating income is based on operating income for three business units (Gas Utility, Gas Marketing and Midstream), and the results are weighted by the budgets for each business unit. Adjusted operating income removes the impacts related to acquisition, divestiture and restructuring activities, mark-to-market adjustments, and other non-operational and non-recurring items.

These internal non-GAAP operating metrics should not be considered as an alternative to, or more meaningful than, GAAP measures.

The following table presents a reconciliation of operating income to adjusted operating income.

In millions	Gas Utility		Gas Marketing		Midstream		Other/ Eliminations			Consolidated
Operating income [GAAP]	$	350.8	$	49.3	$	24.3	$	(5.8	)	$	418.6

Pay vs Performance [Table Text Block]

Pay versus performance

In accordance with rules adopted by the Securities and Exchange Commission pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we are providing the following disclosure regarding executive compensation for our principal executive office (“PEO”) and Non-PEO NEOs and Company performance for the fiscal years listed below.

Refer to the CD&A starting on page 33 for a complete description of how executive compensation relates to Company performance and how the compensation and human resources committee makes its decisions.

(3)

The peer group TSR in this table utilizes the S&P 500 Utilities Index (“S&P Index”), which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in the 2023 Annual Report on Form 10-K. The comparison assumes $100 was invested for the period starting September 30, 2020, through the end of the listed year in the Company and in the S&P Index, respectively. All dollar values assume reinvestment of the pre-tax value of dividends paid by companies, where applicable, included in the S&P Index. Historical stock performance is not necessarily indicative of future stock performance.

(4)

Net economic earnings per share performance summarized above is based on our average basic net economic earnings per share over a period of three years. Net economic earnings exclude from net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisitions, divestiture and restructuring activities, and the largely non-cash impacts of impairments and other non-recurring or unusual items, such as certain regulatory, legislative or GAAP standard-setting actions.
