PROXY STATEMENT

COMMERCE BANCSHARES, INC.

1000 Walnut Street

Kansas City, Missouri 64106

Annual Meeting April 24, 2026

SOLICITATION

This Proxy Statement, the accompanying proxy card and the 2025 Annual Report to Shareholders of Commerce Bancshares, Inc. (the “Company” or “Commerce”), are first being made available to security holders on or about March 13, 2026. The Board of Directors of the Company (the “Board” or “Board of Directors”) is soliciting your proxy to vote your shares at the Annual Meeting of Shareholders (the “Meeting”) on April 24, 2026. The Board is soliciting your proxy to give all shareholders of record the opportunity to vote on matters that will be presented at the Meeting. This Proxy Statement provides you with information on these matters to assist you in voting your shares.

What is a Proxy?

A proxy is your legal designation of another person (the proxy) to vote on your behalf. By completing and returning the enclosed proxy card, you are giving David W. Kemper and John W. Kemper, who were appointed by the Board, the authority to vote your shares in the manner you indicate on your proxy card.

Why did I receive more than one proxy card?

You will receive multiple proxy cards if you hold your shares in different ways (e.g., joint tenancy, trusts, custodial accounts) or in multiple accounts. If your shares are held by a broker, banker, trustee or nominee (i.e., in “street name”), you will receive your proxy card or other voting information from your broker, bank, trustee, or nominee, and you will return your proxy card or cards to your broker, bank, trustee or nominee. You should vote on and sign each proxy card you receive.

Only one Notice of Internet Availability of Proxy Materials or set of printed proxy materials was delivered to my address, but there are two or more shareholders at this address. How do I request additional copies of the proxy materials?

Computershare Trust Company, N.A. (“Computershare”), the entity retained to mail the Notice of Internet Availability of Proxy Materials or printed proxy materials to the Company’s registered owners, has been instructed to deliver only one notice or set of printed proxy materials to multiple security holders sharing an address unless the Company has received contrary instructions from you or one of the other shareholders. The Company will promptly deliver a separate copy of the notice or set of printed proxy materials for this year’s Meeting or for any future meetings to any shareholder upon written or oral request. To make such request, please contact Computershare at 800-317-4445, hearing impaired/TDD at 800-952-9245, or write to Computershare, P.O. Box 43006, Providence RI 02940-3006. Overnight correspondence should be sent to Computershare, 150 Royall St., Suite 101, Canton, MA 02021. Similarly, you may contact Computershare through any of these methods if you receive multiple notices or sets of printed proxy materials and would prefer to receive a single copy in the future.

VOTING INFORMATION

Who is qualified to vote?

You are qualified to receive notice of and to vote at the Meeting if you owned shares of common stock, $5.00 par value, of the Company (“Common Stock”), at the close of business on the record date of Tuesday, February 17, 2026.

How many shares of Common Stock may vote at the Meeting?

As of February 17, 2026, there were 147,283,966 shares of Common Stock outstanding and entitled to vote. Each share of Common Stock is entitled to one vote on each matter presented.

What is the difference between a “shareholder of record” and a “street name” holder?

These terms describe how your shares are held. If your shares are registered directly in your name with Computershare, the Company’s transfer agent, you are a “shareholder of record.” If your shares are held in the name of a broker, bank, trustee or other nominee as a custodian, you are a “street name” holder.

Table of Contents

How do I vote my shares?

If you are a “shareholder of record,” you have several choices. You can vote your proxy:

•online,

•over the telephone, or

•by requesting materials and using the proxy card enclosed with the materials.

Please refer to the specific instructions set forth on the Notice or proxy card. For security reasons, the electronic voting system has been designed to authenticate your identity as a shareholder.

If you hold your shares in “street name,” your broker, bank, trustee or nominee will provide you with materials and instructions for voting your shares.

Can I vote my shares in person at the Meeting?

The Meeting will be a virtual meeting. You are entitled to attend and participate in the Meeting only if you were a shareholder of record as of the record date or hold a valid proxy for the meeting. Those shareholders will be able to attend the Meeting virtually, vote their shares and submit questions during the Meeting via live audio webcast by visiting: https://meetnow.global/M6FQCW6. To participate, you will need the 16-digit control number included in your proxy materials or on your proxy card. Please note that there will be no in-person meeting for you to attend.

What are the Board’s recommendations on how I should vote my shares?

The Board recommends that you vote your shares as follows:


			Proposal One			FOR the election of all four nominees for the 2029 Class of Directors with three-year terms expiring at the 2029 Annual Meeting of Shareholders.

			Proposal Two			FOR the ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm (independent auditors) for the fiscal year ending December 31, 2026.

			Proposal Three			FOR the approval of the Company’s executive compensation (Say on Pay).

What are my choices when voting?


			Proposal One			You may cast your vote in favor of electing the nominees as Directors or withhold your vote on one or more nominees.

			Proposal Two			You may cast your vote in favor of, or against, the proposal, or you may elect to abstain from voting your shares.

			Proposal Three			You may cast your vote in favor of, or against, the proposal, or you may elect to abstain from voting your shares.

Shareholders do not have dissenters’ rights of appraisal in connection with these proposals.

How would my shares be voted if I do not specify how they should be voted?

If you sign and return your proxy card without indicating how you want your shares to be voted, the proxies will vote your shares as follows:


			Proposal One			FOR the election of all four nominees for the 2029 Class of Directors with terms expiring at the 2029 Annual Meeting of Shareholders.

			Proposal Two			FOR the ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm (independent auditors) for the fiscal year ending December 31, 2026.

			Proposal Three			FOR the approval of the Company’s executive compensation. (Say on Pay).

How are votes withheld, abstentions and broker non-votes treated?

If your shares are held in street name, unless you provide voting instructions to your broker, bank, trustee, or other nominee, your shares will not be voted on Proposals One or Three. Those unvoted shares are referred to as broker non-votes and will be treated as not entitled to vote and have no effect on the outcome. In the election of Directors, broker non-votes will be considered solely for quorum purposes and are not counted for the election of Directors; withheld votes will be treated as

Table of Contents

votes against a Director. On Proposal Two (ratification of the appointment of KPMG LLP), your broker, bank, trustee, or other nominee may exercise its discretion and vote on Proposal Two. Abstentions will be treated as votes against Proposal Two. On Proposal Three (approval of the Company’s executive compensation), abstentions will be treated as votes against Proposal Three.

Can I change my vote after I have mailed in my proxy card?

If you are a “shareholder of record,” you may revoke your proxy by doing one of the following:

•by sending a written notice of revocation to the Secretary of the Company that is received prior to the Meeting, stating that you revoke your proxy;

•by delivery of a later-dated proxy (including a telephone or online vote) and submitting it so that it is received prior to the Meeting in accordance with the instructions included on the proxy card(s); or

•by attending the meeting online at https://meetnow.global/M6FQCW6 and voting your shares at the virtual meeting. To participate, you will need the 16-digit control number included in your proxy materials or on your proxy card.

If you hold shares in “street name,” contact your broker, bank, trustee or other nominee for directions on how to change your vote.

What vote is required to approve each proposal?


			Proposal One			requires the number of affirmative votes of those shares represented by proxy and entitled to vote thereon at the Meeting to exceed the number of “withhold” votes for the directors.

			Proposal Two			requires the affirmative vote of a majority of those shares represented by proxy and entitled to vote thereon at the Meeting.

			Proposal Three			requires the affirmative vote of a majority of those shares represented by proxy and entitled to vote thereon at the Meeting. The vote on Proposal Three is a non-binding advisory vote.

While the Company’s directors will be elected by plurality vote at the Annual Meeting, as further described below under “Corporate Governance – Committees of the Board – Committee on Governance/Directors,” any director nominee in an uncontested election who receives a greater number of votes “withheld” than votes “for” his or her election is required, pursuant to the Company’s Bylaws, to promptly tender his or her resignation to the Board of Directors for consideration.

Who will count the votes?

Representatives from Computershare, will count the votes and provide the results to the Inspectors of Election who will then tabulate the votes at the Meeting.

Who pays the cost of a proxy solicitation?

The cost of solicitation of proxies will be borne by the Company. In addition to solicitation by mail, proxies may be solicited personally or by telephone, facsimile transmission or via email by regular employees of the Company. Sodali & Co, 333 Ludlow Street, 5th Floor, South Tower, Stamford, Connecticut 06902, has been retained by the Company, at an estimated cost of $11,500 plus reasonable out-of-pocket expenses, to aid in the solicitation of proxies; shareholders may contact Sodali & Co, at (800) 662-5200 and brokers and banks may contact Sodali & Co, at (203) 658-9400. Brokerage houses and other custodians, nominees and fiduciaries may be requested to forward soliciting material to their principals and the Company will reimburse them for the expense of doing so. This Proxy Statement and proxy will be first sent to security holders on or about March 13, 2026.

Is this Proxy Statement the only way that proxies are being solicited?

No. As stated above, the Company has retained Sodali & Co to aid in the solicitation of proxy materials. In addition to mailing these proxy materials, certain directors, officers or employees of the Company may solicit proxies by telephone, facsimile transmission, e-mail or personal contact.

COMPOSITION OF THE BOARD, BOARD DIVERSITY AND DIRECTOR QUALIFICATIONS

Composition of the Board

As of December 31, 2025, the full Board consisted of twelve Directors. The Board was divided into three classes consisting of four Directors each. Unless otherwise noted, the Directors in each class serve a three-year term. The term of each class expires at successive Annual Meetings so that the shareholders elect one class of Directors at each Annual Meeting.

Board Diversity

The Committee on Governance/Directors seeks director nominees who possess a broad range of skills, experience, professional backgrounds, and perspectives. The Committee believes that a diversity of viewpoints enhances the Board’s effectiveness and its oversight of the Company, while reflecting the communities and customers the Company serves. In evaluating nominees, the Committee considers multiple factors, including areas of expertise, geographic representation, and other relevant attributes to develop a diverse pool of qualified candidates.

Director Qualifications

With respect to its recommendations of prospective candidates to the Board, the Committee on Governance/Directors may establish the criteria for Director service and will consider, among other things, the independence of the candidates under applicable standards and such experience and moral character as to create value to the Board, the Company and its shareholders. With respect to incumbent candidates, the Committee on Governance/Directors also considers meeting attendance, meeting participation and ownership of Company stock. The criteria and selection process are not standardized and may vary from time to time. Relevant experience in business, government, the financial industry, cybersecurity, education and other areas are prime measures for any nominee. Additional areas of expertise typically sought by the Committee include, but are not limited to: audit and controls, corporate governance, finance, accounting, major lines of business within the Company, business strategy, specific industries strategically important to the Company, and risk management.

PROPOSAL ONE

ELECTION OF THE 2029 DIRECTORS

Director Nominees

Effective as of the date of the Meeting, the full Board will consist of twelve Directors. The Board will be divided into three classes consisting of four Directors each.

The election of four Directors to the 2029 will take place at the Meeting. At its meeting on February 6, 2026, the Board approved the recommendation of the Committee on Governance/Directors that four 2029 Class Directors be elected for a three-year term.

If elected, each 2029 Class Director nominee will serve on the Board until the Annual Meeting in 2029, or until their successors are duly elected and qualified in accordance with the Company’s Bylaws. If any of the four nominees should become unable to accept election, the persons named on the proxy card as proxies may vote for such other person(s) recommended by the Company’s Board of Directors. Management has no reason to believe that any of the four nominees for election named below will be unable to serve.

CORPORATE GOVERNANCE

Corporate Governance Guidelines and Code of Ethics

The Board has adopted guidelines on significant corporate governance matters that, together with the Company’s Code of Ethics and other policies, create the corporate governance standards for the Company. You may view the Corporate Governance Guidelines on the Company’s website at https://investor.commercebank.com/overview/corporate-governance/, where you will also find the Corporate Code of Ethics, the Code of Ethics for Senior Financial Officers, the Related Party Transaction Policy, and the charters of the Audit and Risk Committee, Committee on Governance/Directors and the Compensation and Human Resources Committee.

Each Director and all executive officers are required to complete annually a Director and Executive Officer Questionnaire (“Questionnaire”). The information contained in the responses to the Questionnaire is used, in part, to determine Director independence and identify material transactions with the Company in which a Director or executive officer may have a direct or indirect material interest.

Insider Trading Policy

The Company has adopted a Policy regarding insider trading that governs the purchase, sale, and other dispositions of the Company’s securities by directors, officers and employees of the Company, and by the Company itself, that is designed to promote awareness and compliance with insider trading laws, rules, regulations and applicable NASDAQ listing standards. A copy of the Company’s Insider Trading Policy can be found in Exhibit 19 to the Company’s Annual Report on Form 10-K.

Shareholder Communications

The Board has not adopted a formal policy for shareholder communications. We believe a formal policy is unnecessary because the Company has a longstanding practice that shareholders may communicate with the Board or any individual Director through the Secretary of the Company, by addressing such communications to Corporate Secretary, Commerce Bancshares, Inc., 1000 Walnut Street, Kansas City, Missouri 64106. The Secretary will forward all such communications to the Board or any individual Director. The Secretary will not forward any communications that: (i) constitute commercial advertising of products; (ii) contain offensive language or material; (iii) are not legible or coherent; or (iv) are in the nature of customer complaints that can be handled by Company management.

Director Independence

In accordance with the rules of the NASDAQ Stock Market LLC (“NASDAQ”), the Board, on the recommendation of the Committee on Governance/Directors, determines the independence of each Director and nominee for election as a Director. The Committee on Governance/Directors applies the definition of “independent director” adopted by NASDAQ to information derived from responses to the Questionnaire and from research of the Company’s records provided by the General Counsel, Controller and Auditor of the Company. The Board, on the basis of the recommendation of the Committee on Governance/Directors, determined that the following non-employee Directors of the Company and Director nominees are independent:


Terry D. Bassham						June McAllister Fowler
Blackford F. Brauer						Alaina G. Maciá
W. Kyle Chapman						Benjamin F. Rassieur, III
Karen L. Daniel						Todd R. Schnuck
Timothy S. Dunn						Christine B. Taylor

______________________________

Based on the NASDAQ definition of “independent director,” the Board determined that David W. Kemper and John W. Kemper, as employed executive officers of the Company, are not independent.

Board Meetings

The Board held four regularly scheduled meetings in 2025 plus two special meetings in June, 2025. In conjunction with scheduled meetings, the Board regularly meets in Executive Session. During Executive Session, the Board has the opportunity to meet without the presence of any non-independent employee directors. All Directors attended at least 75% of the Board and Committee meetings on which they served in 2025. Although it is not the policy of the Company that Directors attend the Annual Meeting of Shareholders, all the Directors attended the 2025 Annual Meeting of Shareholders on April 25, 2025.

Board Leadership Structure

Prior to August 1, 2018, David W. Kemper served as both principal executive officer and chairman of the Board. Combining the principal executive officer position with the chairmanship of the Board was established in the Company’s original governing documents. Until February 8, 2013, under the Company’s Bylaws, the Chairman of the Board was the chief executive officer of the Company by definition. The incorporators of the Company believed in establishing direct accountability to the shareholders for the chief executive officer who is responsible for the day-to-day decisions that affect the Company’s value. A combined Chairman and Chief Executive Officer avoids potential conflicts between incumbents, establishes accountability, and has the added advantage of eliminating additional compensation expense that would result from separating these two functions. Since its incorporation, the financial strength and esteemed reputation the Company has achieved are a testament to, and a direct result of, the leadership of the two people who have held these combined positions, James M. Kemper, Jr. and current Executive Chairman, David W. Kemper. At its meeting on February 8, 2013, the Board amended the Bylaws to permit, but not require, the separation of the positions of Chairman and Chief Executive Officer. At its meeting on April 2, 2018, the Board determined that, effective on August 1, 2018, the positions of Chairman and Chief Executive Officer would be separated, with David W. Kemper assuming the position of Executive Chairman and John W. Kemper assuming the position of President and Chief Executive Officer.

The Chairman of the Committee on Governance/Directors serves as the Lead Director of the Board. The purpose and effect of this designation is to establish leadership in the Board room during the Executive Session of the Board members.

Committees of the Board

The Board has four committees, three of which (the Compensation and Human Resources Committee, the Committee on Governance/Directors, and the Audit and Risk Committee) are standing committees that meet at least once per year. The Compensation and Human Resources Committee, the Committee on Governance/Directors, and the Audit and Risk Committee are comprised solely of non-employee, independent Directors in accordance with NASDAQ listing standards. The members of the Compensation and Human Resources Committee are also “non-employee Directors” under Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and “outside Directors” under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). The charter for each committee is available online as noted herein. The charters are also available in print to any shareholder who makes a request of the Secretary of the Company. Pursuant to the Company’s Bylaws, the Board has established an Executive Committee to meet as necessary. The Executive Committee does not have a charter and consists of both independent, non-employee Directors and employee Directors.

The Executive Committee is comprised of David W. Kemper, John W. Kemper, Terry D. Bassham, Karen L. Daniel, and Todd R. Schnuck. The table below shows the current membership of the standing committees of the Board:

•Leading the Board in its annual review of the Board's performance;

•Recommending to the Board the agenda for the annual meeting;

•Evaluating the quality of the information and analysis presented to the Board and standing committees;

•Evaluating the performance of the Company relative to corporate governance matters, including periodically reviewing and making recommendations concerning the Corporate Governance Guidelines established by the Board.

The Chairman of the Committee on Governance/Directors serves as the Lead Director of the Board and chairs the Board’s Executive Sessions.

Typically, by the end of January of each year, the Committee on Governance/Directors meets and makes its recommendations to the Board of its proposed slate of Directors for the class of Directors to be elected at the next annual meeting; the date, time and place of the annual meeting; and the matters to be placed on the agenda for the annual meeting. At its meeting on January 27, 2026, the Committee on Governance/Directors determined its nominees for the Class of 2029. All of the nominees for the Class of 2029 are current Directors standing for re-election.

The Committee on Governance/Directors will follow the requirements described in the Company’s Bylaws in the event any director nominee in an uncontested election does not receive a “Majority Vote” (meaning the number of votes cast “for” election of the director must exceed the number of “withheld” votes). The requirements include, without limitation, the tender of a resignation by the director nominee, a recommendation by the Committee and a decision by the Board about whether to accept the resignation, and any required next steps. Any director whose resignation is being considered will not participate in the Committee on Governance/Directors recommendation or Board consideration regarding whether or not to accept the resignation. The Company will promptly publicly disclose any Board decision.

The Committee will consider individuals for Board membership that are proposed by shareholders in accordance with the provisions of the Company’s Bylaws. A description of those provisions can be found under “Shareholder Proposals and Nominations” below. The Committee on Governance/Directors will consider individuals proposed by shareholders under the same criteria as all other individuals.

Audit and Risk Committee

The Company has a separately designated standing Audit and Risk Committee established in accordance with Section 3(a)(58)(A) of the Exchange Act. In 2025, the Audit and Risk Committee met four times. The Audit and Risk Committee is comprised solely of independent, non-employee Directors, and is chaired by Mr. Schnuck. The Board has determined that Ms. Daniel and Mr. Schnuck are each an “Audit and Risk Committee financial expert” as required by the SEC and Ms. Daniel is an “Audit and Risk Committee risk expert” as required by Regulation YY as adopted by the Federal Reserve Board. As a regulated financial company, risk evaluation is inherent in overseeing the Company’s financial reporting processes, and the Company’s compliance with legal and regulatory requirements. For that reason, the Audit and Risk Committee is the primary vehicle for risk oversight by the Board and reviews reports at each of its meetings from legal, audit, compliance, credit review, corporate finance and the Enterprise Risk Management Committee (which oversees the Company’s Information Security Strategy Board that directs the Company's Information and Cybersecurity program). The charter of the Audit and Risk Committee may be found on the Company’s website at https://investor.commercebank.com/overview/corporate-governance/.

Additional information on the activities of the Audit and Risk Committee is provided in the section entitled “Audit and Risk Committee Report”.

Board Risk Oversight

The Board is actively engaged in overseeing the Company’s risk management efforts. The Company and Commerce Bank are subject to examination by the Federal Reserve Bank (“Federal Reserve”), the Missouri Division of Finance (“MDOF”) and the Consumer Financial Protection Bureau (“CFPB”). Examinations focus on and evaluate compliance with applicable laws and regulations as well as assessing how the Company, Commerce Bank and their subsidiaries manage credit, market (interest rate), liquidity, operational, legal, compliance, strategic and reputational risks.

To manage these risks, the Company’s management has adopted a Risk Management Governance Structure including, without limitation, the following risk management committees: Enterprise Risk Management Committee, Asset Liability Committee, Consumer Risk Committee, Credit Policy Committee, Operational Risk Committee, Volcker Committee, Commerce Trust Risk Management Committee, and Information Security Strategy Board. These committees routinely report on risk issues and provide updates to the Audit and Risk Committee.

Additionally, the Board and the Audit and Risk Committee regularly review Reports of Examination from the Federal Reserve, MDOF and CFPB. The Audit and Risk Committee periodically meets with officers and examiners of the Federal Reserve and MDOF. Regular presentations are made to the Board and the Audit and Risk Committee by the Chief Financial Officer, the Chief Credit Officer, and the Chief Risk Officer and include matters noted in the Reports of Examination.

Further, the Audit and Risk Committee annually reviews and approves a Risk Appetite Statement presented by management setting forth the Company’s general appetite for credit, liquidity, market, operational, legal, compliance, strategic and reputational risks. The Audit and Risk Committee monitors exposure to and management of these risks by reviewing results of key risk indicators and related risk metrics on a quarterly basis.

Information Security and Data Privacy

The Company has adopted comprehensive information security and data privacy policies, aligned with the National Institute of Standards and Technology (NIST) and International Organization for Standardization (ISO) standards, and regularly benchmarks its information security program against reputable industry assessments. The Company’s security governance framework includes a dedicated information security program that reports regularly to the Information Security Strategy Board, the Operational Risk Committee, the Enterprise Risk Management Committee and the Board’s Audit and Risk Committee.

The Company protects customer information in compliance with Federal Reserve SR Letter 01-15 in support of the Gramm-Leach-Bliley Act (GLBA) section 501(b), section 216 of the Fair and Accurate Credit Transaction Act of 2003 (FACT Act), Health Insurance Portability and Accountability Act (HIPAA), and the Payment Card Industry Data Security Standards (PCI DSS). The Company’s information security program balances security risks with business goals and provides appropriate protections for the confidentiality, integrity and availability of bank and customer information. The program is audited twice each year by Company internal auditors and annually by federal and state regulators. Independent third-party penetration testing is conducted quarterly against external network and high-risk applications. The Company maintains insurance commensurate with assessed levels of security and privacy risk.

Table of Contents

All employees and contractors are required to take regular training on information security requirements and must acknowledge policies and standards annually. In addition, the Company conducts frequent phishing campaigns to test and educate all employees on how to spot phishing attacks and to measure the effectiveness of our training program. The Commerce Privacy Statement, found on the Company’s website at https://www.commercebank.com/security-center/privacy-statement, serves as a standard for all employees for collection, use, retention and security of nonpublic personal information and provides detail on how customers may limit use of their information.

Finally, applications, databases, information technology infrastructure, service providers and business units that handle sensitive information are evaluated annually as part of the information security risk assessment. New applications, infrastructure components and service providers are also assessed prior to integration with existing systems. The Company and Commerce Bank contractually require all service providers, contractors, sub-contractors, or other third parties that process, transmit, access, or store bank or customer data to comply with all relevant Company policies (including, but not limited to, retention, encryption, transmission, and application security policies) and safeguards and to be in compliance with all applicable laws. Additional information concerning the Company's Information and Cybersecurity program is presented in Item 1C of the Company’s 2025 Annual Report on Form 10-K which accompanies this proxy statement.

To foster personal connections and a sense of belonging, Commerce supports several employee-led resource groups and offers an array of competitive benefits, educational assistance, and flexible work schedules to promote financial, emotional, and physical well-being.

•Community Engagement – Commerce builds long-term relationships in the communities in which it operates. We build these relationships over time and in tangible ways such as through employee volunteerism that we formally encourage by providing paid time off for employees who wish to participate. Additionally, the Company ensures lending products and solutions meet the needs of the community, marketing practices support a clear and informative approach to advertising, and employees are motivated to do what’s right for customers. Finally, Commerce offers affordable options for home ownership through various programs for customers. We are proud of the Outstanding CRA rating the Company has received for 30 years for efforts to support low-and moderate-income families.

In addition to satisfying the notice and other requirements of the Company’s Bylaws with respect to the nomination of director candidates, any shareholder who intends to solicit proxies in support of director nominees, other than the Company’s nominees, must also comply with the requirements of Rule 14a-19 under the Exchange Act relating to universal proxies.

Transactions with Related Persons

The Board of Directors has adopted a Related Party Transaction Policy (“Policy”). The purpose of the Policy is to establish procedures for the identification and approval, if necessary, of transactions between the Company and any Director, nominee for Director, beneficial owner of more than 5% of the Company’s securities, executive officer or any person or entity deemed related to any of the foregoing (“Related Party”) that are material or not in the ordinary course of business.

The Policy may be found on the Company’s website at https://investor.commercebank.com/overview/corporate-governance/. The Policy is intended to identify all transactions with Related Parties where payments are made by the Company to or for the direct or indirect benefit of a Related Party. The procedures, discussed in detail in the Policy, include the following:

•The collection and maintenance of a Related Party list derived from the records of the Company and the responses to an annual Questionnaire completed by Directors and executive officers;

•The distribution of the list to the appropriate officers and employees of the Company so that transactions with Related Parties may be identified;

•An annual comparison of the list to payments made by the Company; and

•Preparation and delivery of a report to the General Counsel of the Company for review, analysis and an initial determination of whether the transaction is material and falls within the Policy.

The Policy provides guidance for determination of materiality of Related Party transactions. The amount of the transaction, the application of any exemption or exclusion, the provisions of the Company’s Corporate Code of Ethics, and general principles of corporate transparency may be considered in evaluating materiality. The Policy deems certain transactions exempt and pre-approved, including compensation paid for service as a Director or executive officer, transactions involving depository or similar payment services with fees based on similar transactions with non-related persons, transactions that are the result of a competitive bidding process or certain services provided at regulated rates, transactions arising solely from the ownership of the Company’s equity securities, and transactions available to employees generally. The Policy provides further guidance to the Board or Audit and Risk Committee in regard to the approval or ratification of the transaction and prohibits the participation by a Related Party in the discussion, approval or ratification of a transaction.

Pursuant to the application of the Policy, the following transactions were identified:

•During 2025, Commerce Bancshares, Inc. paid a salary and other compensation of $455,440, a bonus of $328,000, and equity awards of $249,946 to David W. Kemper, Executive Chairman, and father of John W. Kemper.

•During 2025, Commerce Bank paid retirement benefits of $135,098 to Jonathan M. Kemper, retired Chairman Emeritus, Commerce Bank, Kansas City Region, brother of David W. Kemper, and uncle of John W.

•During 2025, Commerce Bank paid a salary and other compensation of $239,984 to Charlotte Kemper Black, Foundation Director, niece of David W. Kemper, and cousin of John W. Kemper.

•Various Related Parties have deposit accounts with Commerce Bank and some Related Parties also have a direct or indirect interest in other transactions with Commerce Bank, including loans in the ordinary course of business, all of which were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the Company, and did not involve more than normal risk of collectability or present other unfavorable features.

Delinquent Section 16(a) Reports

Pursuant to Section 16 of the Exchange Act, the Directors and certain executive officers are required to report, within specified due dates, their initial ownership of the Common Stock on Form 3, and all subsequent acquisitions, dispositions or other transfers of interest in such securities on Form 4 or Form 5, if and to the extent reportable events occur which require reporting by such due dates. The Company is required to identify in its proxy statement whether it has knowledge that any person required to file such a report may have failed to do so in a timely manner. Based on a review, all of the Directors and all executive officers subject to the reporting requirements satisfied such requirements in full, except for the following delinquencies which were filed on either Form 3, Form 4, or Form 5: for Kevin G. Barth and David W. Kemper, delinquent Form 4's were filed to report reinvestment of dividends under the Executive Incentive Compensation Plan.

Director Compensation

An employee of the Company or a subsidiary of the Company receives no additional compensation for serving as a Director. Non-employee Directors of the Company are required to participate in the Stock Purchase Plan for Non-Employee Directors (the “Director Plan”). Under the Director Plan, compensation payable to a non-employee Director is credited to an account in the name of such Director as earned. As of the last business day of each month, the cash balance in a Director’s account is converted to whole shares of Common Stock based on the consolidated closing bid price of the Common Stock as reported by NASDAQ. Any balance remaining in a Director’s account is carried forward for investment in the next month.

As soon as practicable after the end of each year, the Company issues each non-employee Director the number of shares of Common Stock credited to the Director’s account and any cash balance in the account is carried forward for investment in the next year. If a Director dies or ceases to be a non-employee Director during the year, the Company will distribute to the Director (or his or her beneficiary), as soon as reasonably practicable, the number of shares of Common Stock credited to the Director’s account, along with any cash credited to the account. A participant in the Director Plan has no right to vote or receive cash dividends or any other rights as a shareholder with respect to shares credited to the participant’s account until such shares are actually issued.

Each non-employee Director of the Company is paid the following amounts, as applicable: an annual retainer of $130,000; a retainer of $20,000 paid to the Lead Director; a retainer of $10,000 paid to each Committee Chair; a retainer of $20,000 paid to each member of the Audit and Risk Committee; a retainer of $5,000 paid to each member of the Compensation and Human Resources Committee and the Committee on Governance/Directors. All amounts are paid per year in equal quarterly installments. Changes to Directors’ compensation are initiated by the Company’s CEO and presented to the Compensation and Human Resources Committee. The Chairman of the Compensation and Human Resources Committee then presents any changes to the full Board of Directors for its approval.

The Company has a stock ownership requirement of $300,000 for non-employee Directors. New Directors will have 5 years from the election date to meet the stock ownership requirement. With the exception of June McAllister Fowler (who will have until 2027 to be in compliance) and Timothy S. Dunn and Alaina G. Maciá (who will have until 2030 to be in compliance), all non-employee Directors have satisfied the stock ownership requirement as of December 31, 2025.
