#### PROXY STATEMENT

#### FOR THE

#### 2026 ANNUAL MEETING OF SHAREHOLDERS

#### TO BE HELD ON APRIL 30, 2026

#### INTRODUCTION
This Proxy Statement, along with the accompanying Notice of Annual Meeting of Shareholders, contains information about the 2026 Annual Meeting of Shareholders (the "Annual Meeting") of First US Bancshares, Inc. (the "Company"), including any adjournments or postponements of the Annual Meeting. We are holding the Annual Meeting on Thursday, April 30, 2026 at 10:00 a.m., Central Time, in a virtual format via live webcast. The matters to be considered and acted upon are:

(1) the election of 12 directors of the Company;

(2) the ratification of the appointment of Carr, Riggs & Ingram, LLC as independent registered public accountants for the year ending December 31, 2026;

(3) the advisory approval of the Company's executive compensation;

(4) the transaction of such other business as may properly come before the Annual Meeting.

This Proxy Statement relates to the solicitation of proxies by the Board of Directors of the Company (the "Board") for use at the Annual Meeting. On or about March 18, 2026, we began sending a Notice of Internet Availability of Proxy Materials to all shareholders entitled to vote at the Annual Meeting. We will vote all properly executed proxies delivered pursuant to this solicitation during the Annual Meeting and in accordance with instructions given, if any. If no instructions are given, we will vote the proxies as recommended by the Board – FOR all of the nominees listed in Proposal 1 and FOR Proposals 2 and 3 – and in accordance with the instructions of management as to any other matters that may come before the Annual Meeting.

We encourage all of our shareholders to vote at the Annual Meeting, and we hope that the information contained in this document will help you decide how you wish to vote at the Annual Meeting.

**IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE VIRTUAL ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON APRIL 30, 2026: THE COMPANY'S PROXY STATEMENT AND 2025 ANNUAL REPORT ARE AVAILABLE AT www.edocumentview.com/FUSB.** 

**NOTE: If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in "street name," and these proxy materials are being forwarded to you by your broker, bank or other nominee who is considered the shareholder of record with respect to those shares. You must follow the instructions for voting your shares that you receive from your broker, bank or other nominee. Please refer to the section entitled "Voting Shares Held in 'Street Name'" for more information about how to vote your shares.** 

The Company will pay the cost of soliciting proxies. In addition to soliciting proxies by mail, we may solicit proxies by personal interview, telephone, facsimile and electronic communication. Banks, brokers or other nominees will forward the proxy materials to their principals or beneficial owners and obtain authorization for

------

##### [**Table of Contents**](#toc)
the execution of proxies. The Company will, upon request, reimburse banks, brokers and other nominees for their reasonable expenses in forwarding proxy materials to their principals or beneficial owners.

In accordance with rules and regulations adopted by the Securities and Exchange Commission (the "SEC"), we have elected to use a "notice and access" approach, pursuant to which our shareholders (unless such shareholders have specifically requested paper copies of the materials) will receive only the required notification documentation under the notice and access provisions of the SEC rules, which will not include a paper copy of this Proxy Statement or our 2025 Annual Report to Shareholders. This approach conserves paper and reduces our costs of printing and distributing the proxy materials, while providing our shareholders with a convenient method of accessing the materials and voting. On or about March 18, 2026, a Notice of Internet Availability of Proxy Materials (the "Notice") was sent to our shareholders, which contains instructions on how to access and review the proxy materials on the Internet, how to submit your proxy via the Internet or by telephone, and how to request paper copies of the proxy materials, including this Proxy Statement and our 2025 Annual Report to Shareholders.

#### Shareholders Eligible to Vote
You are entitled to vote at the Annual Meeting if you were a holder of the Company's common stock, par value, $.01, per share, as of the close of business on March 6, 2026. Only shareholders as of this date are eligible to vote during the Annual Meeting. At the close of business on March 6, 2026, there were 5,650,157 shares of common stock of the Company outstanding and eligible to receive notice of and to vote at the Annual Meeting. Each shareholder is entitled to one vote in person or by proxy for each share of common stock held on all matters properly to come before the Annual Meeting.

#### How to Participate in the Annual Meeting
You will be able to attend the Annual Meeting online and submit your questions during the meeting by visiting https://meetnow.global/MDUQCQD. You also will be able to vote your shares online by attending the Annual Meeting by webcast. In order to participate, you will need the control number included on your Notice or proxy card if you request a hard copy of the proxy materials. If you are a registered shareholder (i.e., you hold your shares through our transfer agent, Computershare), you do not need to register to attend the Annual Meeting virtually on the internet.

If you hold your shares through an intermediary, such as a bank or broker, and do not have a control number, you must register in advance by following the instructions outlined below. To register to attend the Annual Meeting online, you must submit proof of your proxy power (legal proxy) reflecting your First US Bancshares, Inc. holdings along with your name and email address to Computershare. Requests for registration must be labeled as "Legal Proxy" and be received no later than 4:00 p.m. (Central Time), on April 27, 2026. You will receive a confirmation of your registration by email after Computershare receives your registration materials.

Requests for registration should be directed to Computershare at the following:

• By email: Forward the email from your broker, or attach an image of your legal proxy, to legalproxy@computershare.com

• By mail: Computershare, First US Bancshares, Inc. Legal Proxy, P.O. Box 43001, Providence, RI 02940-3001

#### How to Revoke a Proxy or Change Your Votes
You may revoke your proxy or change your voting instructions prior to the vote during the Annual Meeting. You may enter a new vote by using the Internet or telephone or by mailing a new proxy card or new voting instruction form bearing a later date (which will automatically revoke your earlier voting instructions), which new proxy card must be received prior to the date of the Annual Meeting. You may also enter a new vote by

------

##### [**Table of Contents**](#toc)
participating in the Annual Meeting and voting during the meeting. Your participation in the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically so request.

#### Information About a Quorum
At the Annual Meeting, the presence of a majority of the outstanding shares of the Company's common stock entitled to vote, represented in person or by proxy, shall constitute a quorum for the transaction of business. If a quorum is not present, or if the Chairperson of the Annual Meeting decides that more time is necessary for the solicitation of proxies, then the Chairperson may adjourn the Annual Meeting, with or without a shareholder vote. Alternatively, if there is a shareholder vote to adjourn the Annual Meeting based on the absence of a quorum, the named proxies will vote all shares of common stock for which they have voting authority in favor of the adjournment.

#### Vote Required to Approve Proposals
Assuming the presence of a quorum, the directors of the Company will be elected by a plurality of the shares represented at the Annual Meeting and entitled to vote in the election of directors – in other words, the director nominees receiving the most votes will be elected (Proposal 1). The ratification of the appointment of Carr, Riggs & Ingram, LLC as independent registered public accountants for the year ending December 31, 2026 (Proposal 2) will require the affirmative vote of a majority of the shares represented at the Annual Meeting in person or by proxy and entitled to vote on the matter. Proposal 3 calls for the advisory (non-binding) approval of the Company's executive compensation and will require for adoption the affirmative vote of a majority of the shares represented at the Annual Meeting in person or by proxy and entitled to vote on the matter.

Following the Annual Meeting, we will file a Current Report on Form 8-K with the Securities and Exchange Commission (the "SEC") to disclose the results of voting on each proposal, as required by applicable rules.

#### Abstentions
A shareholder may abstain from voting or withhold his or her vote, as applicable (collectively, "abstentions"), with respect to each item submitted for shareholder approval, including the election of directors. Abstentions will be counted as present for purposes of determining the existence of a quorum but will be counted as not voting on any proposal brought before the Annual Meeting. Based on the plurality voting standard, abstentions will have no effect on the election of directors (Proposal 1). An abstention as to the ratification of the appointment of Carr, Riggs & Ingram, LLC as independent registered public accountants for the year ending December 31, 2026 (Proposal 2) and the advisory approval of the Company's executive compensation (Proposal 3) will have the same effect as voting against these proposals, given that the outcome of each proposal is determined by the shares represented at the Annual Meeting and entitled to vote on the matter.

#### Voting Shares Held in "Street Name"
If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in "street name," and these proxy materials are being forwarded to you by your broker, bank or other nominee who is considered the shareholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote, and you are also invited to participate in the virtual Annual Meeting. Your broker, bank or other nominee has enclosed a voting instruction card for you to use in directing the broker, bank or other nominee regarding how to vote your shares. If you hold your shares in "street name," it is critical that you return the voting instruction card as directed by your broker, bank or other nominee if you want your votes to count in the election of directors (Proposal 1) and with respect to the non-binding advisory vote regarding the Company's executive compensation (Proposal 3).

Under applicable law, if you hold your shares in "street name" and do not indicate to your broker, bank or other nominee how you want your shares to be voted in the election of directors (Proposal 1) or the executive

------

##### [**Table of Contents**](#toc)
compensation matter (Proposal 3), then your broker, bank or other nominee may not vote on these matters. **Therefore, if you hold your shares in "street name" and do not instruct your bank, broker or other nominee on how to vote in the election of directors or with respect to the executive compensation matter, your shares will not be voted with respect to such matters or on any other proposal with respect to which your broker, bank or other nominee does not have discretionary authority (resulting in a "broker non-vote").**

Broker non-votes are counted for general quorum purposes but are not taken into account when determining voting outcomes with respect to any matter for which a broker does not have discretionary authority to vote. Broker non-votes will not be counted for purposes of the election of directors (Proposal 1) and will have no effect on the outcome of such proposal. Broker non-votes will not be taken into account in determining the outcome of the non-binding advisory vote regarding executive compensation (Proposal 3). Your bank, broker or other nominee will continue to have discretion to vote any uninstructed shares on the ratification of the appointment of Carr, Riggs & Ingram, LLC as our independent registered public accountants for the year ending December 31, 2026 (Proposal 2); therefore, there should be no broker non-votes with respect to this item.

#### PROPOSAL 1

#### ELECTION OF DIRECTORS
The Company's Bylaws provide that the Board shall consist of not less than three and not more than 25 directors, and, if a number is not fixed by the Board, the Bylaws state that there shall be 16 directors. There are currently 12 directors serving on the Board. All current members of our Board will stand for reelection at the Annual Meeting. The Nominating and Corporate Governance Committee and the Board have both determined that a Board consisting of 12 persons is practical and efficient at this point in time.

Based on the nominations of the Nominating and Corporate Governance Committee, the Board recommends that the shareholders elect the 12 director nominees named below to hold office until the 2027 Annual Meeting of Shareholders of the Company and until their successors are elected and qualified. Unless "Withhold" is noted as to all or some of the nominees, proxies will be voted at the Annual Meeting FOR the election of the 12 nominees to the Board. Shareholders may not vote for a greater number of persons than the number of nominees named. **THE BOARD RECOMMENDS THAT YOU VOTEFOR THE ELECTION OF THE 12 NOMINEES.**

While we know of no reason why any nominee would be unable to serve as a director, if, before the voting during the Annual Meeting, any person nominated to be elected as a director is unable to serve, then the shares that would otherwise be voted for that person may be voted for the election of a substitute person recommended by the Board.

The following provides certain biographical information about the individuals who have been nominated for election as directors of the Company. The biographical information for each of the nominees below contains a description of the individual's service as a director; business experience; director positions held currently or at any time during the last five years, if applicable, with a company registered pursuant to Section 12 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or an investment company; information regarding involvement in certain legal or administrative proceedings, if applicable; and the experiences, qualifications, attributes and skills that caused the Board to determine that the individual should serve as a director. The stock ownership with respect to each nominee is set forth in the table entitled "Security Ownership of Certain Beneficial Owners and Management" that appears in this Proxy Statement.

Following the Annual Meeting, the Company, as the sole shareholder of First US Bank (the "Bank"), intends to reelect all of the newly-elected directors of the Company as directors of the Bank. Information regarding the executive officers of the Company who are not directors is also provided below.

None of the directors or executive officers are related to any other director or executive officer of the Company.

#### CORPORATE GOVERNANCE
The Company is committed to having sound corporate governance principles. Operating in accordance with such principles is essential to running the Company's business effectively and to maintaining the Company's integrity in the marketplace. The Company's Board has adopted a Code of Business Conduct and Ethics that sets forth basic principles to guide the Company's and the Bank's employees, including the Chief Executive Officer, the Chief Financial Officer and other senior executive officers, in their conduct and compliance with applicable laws and governance principles. A copy of the Code of Business Conduct and Ethics is available on our website at https://www.fusb.com under the tabs "Investors – Governance – FUSB Policies." We will furnish any person without charge, upon written request, a copy of the Code of Business Conduct and Ethics. In the event the Company amends or waives any of the provisions of the Code of Business Conduct and Ethics applicable to our Chief Executive Officer, the Chief Financial Officer and other senior executive officers that relate to any element of the definition of "code of ethics" enumerated in Item 406(b) of Regulation S-K under the Exchange Act, the Company intends to disclose these actions on the Company's website.

The following is a summary of the Company's director independence standards, the Board and committee structure, the director nomination process and the procedures for shareholders to follow to communicate with the Board.

#### Director Independence
The Nasdaq Stock Market, LLC, the exchange on which the Company's common stock is listed ("Nasdaq"), requires that a majority of the Company's Board members be "independent." Accordingly, because the Board currently has 12 members, at least seven of the directors must be independent. In accordance with Nasdaq's listing rules, a director is not considered to be independent unless the Board determines that the director has no relationship with the Company or its subsidiaries (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company or any of its subsidiaries) that would interfere with the exercise of the director's independent judgment in carrying out the responsibilities of a director. Members of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee also must meet the applicable independence tests in the Nasdaq listing rules and the federal securities laws.

The Board has determined that none of the directors standing for reelection, with the exception of Mr. House, has any material relationship with the Company or any of its subsidiaries (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company or any of its subsidiaries) that would interfere with the exercise of independent judgment in carrying out his or her responsibilities. In making this determination, the Board considered transactions and relationships between each director or his or her immediate family and the Company, its subsidiaries and their employees. The purpose of this review was to determine whether any such transactions or relationships were material and possibly inconsistent with a determination that the director was independent. Mr. House is not independent because of his employment as the President and Chief Executive Officer of the Company and the Bank.

While conducting its review of director independence, the Board specifically considered the various deposit, loan and other relationships that each director has with the Bank, including the transactions disclosed under "Transactions with Related Persons," but determined in each case that these relationships did not interfere with their exercise of independent judgment in carrying out their responsibilities as directors. Additionally, the Board considered that the Company has leased various properties from entities with which Mr. Thompson is affiliated since the Bank acquired The Peoples Bank in 2018. The Company's lease arrangements with these entities are negotiated on the same basis and subject to the same terms and conditions as the Company's other similar lease arrangements. The Board determined that the amounts paid by the Company to Mr. Thompson's entities during each of the last three fiscal years were not material to the Company or Mr. Thompson. Based on this review, the Board concluded that the Company's relationship with Mr. Thompson's entities does not interfere with Mr. Thompson's exercise of independent judgment in carrying out his responsibilities as a director.

#### Company Leadership Structure
The business of the Company is managed under the direction of the Board, which is elected by our shareholders. The basic responsibility of the Board is to lead the Company by exercising its business judgment to act in what each director reasonably believes to be the best interests of the Company and its shareholders. Leadership is important to the effective operation of the Board for the benefit of the Company. The role of the Chairperson includes providing continuous feedback on the direction, performance and strategy of the Company, presiding over meetings of the Board, setting the Board's agenda with management and the Lead Independent Director, and leading the Board in anticipating and responding to risks faced by the Company.

The roles of Chief Executive Officer and Chairperson of the Board were separate until January 2025, when the Board, at the recommendation of the Nominating and Corporate Governance Committee, elected Mr. House, the President and Chief Executive Officer of the Company and the Bank, as Chairperson of the Board. Previously, he had served as Vice Chairperson of the Board since November 2022. Also in January 2025, the Nominating and Corporate Governance Committee recommended, and the Board approved, designating Mr. Briggs as the Vice Chairperson of the Board and the Lead Independent Director in accordance with the Company's Lead Director Charter. The Board believes that this leadership structure will enhance communication and cooperation among the directors and members of management. The Board may reconsider this leadership structure from time to time based on then-current considerations.

#### Risk Oversight
The Company is exposed to a number of risks and regularly undertakes a review to identify and evaluate these risks and develop plans to manage them effectively. While the Chief Executive Officer has overall responsibility for risk assessment, management and prioritization, the Board has an active role in the risk oversight process.

The Board regularly reviews information regarding the Company's financial, credit, liquidity, operational, legal, regulatory, compliance, reputational and strategic risks based on reports from management, including the Chief Executive Officer and the Chief Financial Officer. The Audit Committee is primarily responsible for overseeing the Company's enterprise risk management ("ERM") program, including the process by which management assesses, prioritizes and manages the Company's material risks, and receives periodic reports from the Chief Risk Officer on the status of the ERM program. Certain other committees of the Board are responsible for specific oversight of the risk oversight process when a particular risk falls within the purview of that particular committee:

➣ The Audit Committee reviews the Company's financial risks (including risks required to be monitored under the Sarbanes-Oxley Act) and risks relating to financial reporting, audit matters and internal controls.

➣ The Nominating and Corporate Governance Committee specifically oversees risks associated with the independence of Board members, potential conflicts of interest and governance items.

➣ The Compensation Committee of the Board oversees the management of risks relating to the Company's compensation policies, plans, and practices, including executive compensation.

➣ The Retail, Operations and Compliance Committee of the Bank's Board of Directors oversees risk management policies with respect to retail products and operational functions, along with certain compliance and audit functions.

➣ The Information Technology Steering Committee oversees information technology services, cybersecurity and third-party technology risk exposure of the Bank.

➣ The Directors' Loan Committee oversees risks relative to certain loan and credit functions and approval processes of the Bank.

------

##### [**Table of Contents**](#toc)
The conclusions of each Board committee with respect to issues falling within the purview of that particular committee are brought to the attention of all Board members at the regularly-scheduled meetings of the Board. This enables the Board and its committees to coordinate with respect to the risk oversight function and responsibility.

#### Board Structure and Committees
The Board conducts its business through meetings of the Board and Board committees. Further, executive sessions of the independent directors of the Board are to be held at least two times a year and otherwise as needed. These sessions are chaired by the Chairperson of the Board or another independent director selected by a majority of the independent directors.

During 2025, the Board met ten times in regularly scheduled meetings and held one special meeting. All of the incumbent directors attended at least 75% of the aggregate of the total number of meetings of the Board and the total number of meetings held by all committees of the Board on which he or she served during the year.

Directors are encouraged but not required to attend the Annual Meeting of Shareholders each year. Nine individuals then serving as the Company's directors attended the Company's 2025 Annual Meeting of Shareholders held on May 1, 2025, with two directors not attending.

#### Audit Committee
The Audit Committee assists the Board with its oversight responsibilities with respect to the financial reports and other financial information provided by the Company to its shareholders and others, the Company's financial policies and procedures and disclosure controls and procedures, the Company's system of internal controls and the Company's auditing, accounting and financial reporting processes. The Audit Committee operates under a written charter, a copy of which is posted on the Company's website at https://www.fusb.com under the tabs "Investors – Governance – FUSB Policies." The Audit Committee is required on an annual basis to review and reassess the adequacy of its charter and recommend any changes to the full Board. The Audit Committee last reviewed and assessed the adequacy of its charter on March 12, 2026. The Audit Committee met 12 times during 2025. The Audit Committee Report appears later in this Proxy Statement.

Certain Nasdaq listing rules and the federal securities laws require that at least one member of the Audit Committee must have an understanding of generally accepted accounting principles and financial statements, the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves, experience preparing, auditing, analyzing or evaluating financial statements or experience actively supervising one or more persons engaged in such activities, an understanding of internal control over financial reporting and an understanding of audit committee functions. The Board has determined that currently Marlene M. McCain and Robert Stephen Briggs each has the requisite attributes of an "audit committee financial expert."

The current members of the Audit Committee are Marlene M. McCain, Chairperson, Robert Stephen Briggs, Robert C. Field, Jack W. Meigs, Staci M. Pierce and Bruce N. Wilson. The Board has carefully evaluated the backgrounds of the members of the Audit Committee and determined that such members qualify as "independent," as defined in the applicable Nasdaq listing rules, and such members satisfy the heightened independence standards under SEC rules.

#### Compensation Committee
The Compensation Committee assists the Board in overseeing and determining executive compensation. Among other responsibilities, the Compensation Committee reviews, recommends and approves salaries and other compensation of the Company's executive officers and administers the Company's equity compensation

##### [**Table of Contents**](#toc)
plans that may be in place from time to time. The Chief Executive Officer assists the Compensation Committee with determining the amount of compensation to be paid to the other executive officers but does not play a role in the final determination or approval of his own compensation. The Compensation Committee operates under a written charter, a copy of which is posted on the Company's website at https://www.fusb.com under the tabs "Investors – Governance – FUSB Policies." The Compensation Committee is required on an annual basis to review and reassess the adequacy of its charter and recommend any changes to the full Board. The Compensation Committee last reviewed and assessed the adequacy of its charter on March 12, 2026. The Compensation Committee met four times during 2025. The Compensation Committee Report appears later in this Proxy Statement.

The Compensation Committee has reviewed the Company's compensation programs, plans and practices for all of its employees as they relate to risk management and risk-taking initiatives to ascertain if they serve to encourage or incentivize risks that are "reasonably likely to have a material adverse effect" on the Company. As a result of this process, the Compensation Committee concluded and informed the Board that, based on the Company's current compensation programs, plans and practices, there are no such risks.

The current members of the Compensation Committee are Bruce N. Wilson, Chairperson, J. Lee McPhearson, Jack W. Meigs, Aubrey S. Miller and Staci M. Pierce. The Board has carefully evaluated the backgrounds of the members of the Compensation Committee and determined that such members qualify as "independent," as defined in the applicable Nasdaq listing rules, including the heightened independence standards applicable to members of compensation committees of listed companies.

#### Nominating and Corporate Governance Committee
Among other responsibilities, the Nominating and Corporate Governance Committee reviews and recommends the selection of directors and members of committees of the Board and reviews and establishes the governance practices of the Company. The Nominating and Corporate Governance Committee operates under a written charter, a copy of which is posted on the Company's website at https://www.fusb.com under the tabs "Investors – Governance – FUSB Policies." The Nominating and Corporate Governance Committee is required on an annual basis to review and reassess the adequacy of its charter and recommend any changes to the full Board. The Nominating and Corporate Governance Committee last reviewed and assessed the adequacy of its charter on March 12, 2026. The Nominating and Corporate Governance Committee met six times during 2025.

The members of the Nominating and Corporate Governance Committee are Jack W. Meigs, Chairperson, J. Lee McPhearson, Aubrey S. Miller and Bruce N. Wilson. The Board has carefully evaluated the backgrounds of the members of the Nominating and Corporate Governance Committee and determined that such members qualify as "independent," as defined in the applicable Nasdaq listing rules.

#### Executive Committee
Among other responsibilities, the Executive Committee provides advice to the executive officers of the Company and takes actions on behalf of the Board between meetings of the Board. The Executive Committee is required on an annual basis to review and reassess the adequacy of its charter and recommend any changes to the full Board. The Executive Committee met three times during 2025.

The members of the Executive Committee are James F. House, Chairperson, Robert Stephen Briggs, Robert C. Field, David P. Hale, Marlene M. McCain and Aubrey S. Miller.

#### Consideration of Director Nominees

#### Criteria and Board Composition
Criteria that are used by the Nominating and Corporate Governance Committee in connection with evaluating and selecting new directors include factors relating to whether the candidate would meet the definition

##### [**Table of Contents**](#toc)
of "independent," as defined by the applicable Nasdaq listing rules, as well as the candidate's skills, occupation and experience in the context of the needs of the Board. The Board believes that the backgrounds and qualifications of the directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities.

The Nominating and Corporate Governance Committee continually reviews the qualifications and responsibilities of all directors in consideration of the Board's overall responsibility to shareholders. The Nominating and Corporate Governance Committee also considers issues of relevant experience, intelligence, independence, commitment, integrity, diligence, conflicts of interest, age, compatibility with the Company's other Board members and management team, understanding of the Company's business and culture, the ability to act in the best interests of the shareholders and other factors deemed relevant. The goal of this process is to assemble a group of directors with deep, varied experience, sound judgment and commitment to the success of the Company. For a discussion of the individual experience and qualifications of our directors, refer to "Proposal 1 – Election of Directors" in this Proxy Statement.

#### Process for Identifying and Evaluating Director Nominees
The process followed by the Nominating and Corporate Governance Committee to identify and evaluate candidates includes requests to Board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates, and interviews of selected candidates by members of the Nominating and Corporate Governance Committee and the Board. Assuming that the appropriate biographical and background material discussed below is provided on behalf of candidates recommended by shareholders, the Nominating and Corporate Governance Committee will evaluate those candidates by applying substantially the same criteria and following substantially the same process as that used for candidates submitted by Board members. With respect to Mr. Gordon, who was elected to the Board following the 2025 Annual Meeting of Shareholders, such candidate was recommended to the Nominating and Corporate Governance Committee by other current members of the Board.

#### Director Nominees Proposed by Shareholders
The Nominating and Corporate Governance Committee will consider candidates recommended by shareholders for inclusion by the Board in the slate of nominees that the Board recommends to the shareholders for election. In considering whether to recommend any candidate for inclusion in the Board's slate of recommended director nominees, including candidates recommended by shareholders, the Nominating and Corporate Governance Committee applies the selection criteria and follows the process described above.

Shareholders may recommend individuals for the Nominating and Corporate Governance Committee to consider as potential director candidates by submitting the following information to the Nominating and Corporate Governance Committee, c/o Corporate Secretary of First US Bancshares, Inc., 131 West Front Street, P.O. Box 249, Thomasville, Alabama 36784:

#### TRANSACTIONS WITH RELATED PERSONS
The Company recognizes that transactions between the Company or its subsidiaries and any of its directors or executive officers may present potential or actual conflicts of interest that are not in the best interests of the Company and its shareholders. Therefore, as a general matter and in accordance with the Company's Code of Business Conduct and Ethics, the Company prefers to avoid such transactions. Nevertheless, there are situations where such transactions may be in, or may not be inconsistent with, the best interests of the Company and its shareholders. Therefore, the Company has adopted a written policy and procedures that require the Audit Committee to review and, if appropriate, to approve or ratify any such transactions.

#### Policy and Procedures Regarding Related Person Transactions
The Company's Related Person Transaction Policy sets forth the process for reviewing, approving and ratifying transactions involving the Company and its subsidiaries and "related persons." "Related persons" include directors, director nominees and executive officers and their immediate family members, and shareholders owning 5% or more of the Company's outstanding common stock and their immediate family members. It is the Company's policy to approve and ratify transactions involving related persons only when the Board, acting through the Audit Committee, determines that the transaction in question is in, or is not inconsistent with, the best interests of the Company and its shareholders.

The procedures provide that, prior to entering into a related person transaction, management or the affected director or executive officer must bring the matter to the attention of a designated individual who will assess whether the matter should be considered by the Audit Committee. If a member of the Audit Committee is involved in the proposed transaction, he or she will be recused from all discussions and decisions about the transaction. To the extent that a related person transaction is not identified in advance, the terms of the transaction will be reviewed and evaluated by the Audit Committee. Only transactions that are in, or that are not inconsistent with, the best interests of the Company and its shareholders are approved or ratified by the Audit Committee.

#### Certain Transactions with Related Persons
During the 2024 and 2025 fiscal years, the Company leased various properties from entities with which Mr. Tracy E. Thompson, one of the Company's current directors, is affiliated. Pursuant to those lease arrangements, the Company paid a limited liability company, of which Mr. Thompson is the sole member, $160,064 in 2024. The Company's lease negotiations with Mr. Thompson's entities are negotiated on the same basis and subject to the same terms and conditions as the Company's other similar lease arrangements.

Certain directors and executive officers of the Company and their family members are customers of, and have had transactions with, the Bank in the ordinary course of business, and additional transactions likely will take place in the ordinary course of business. The federal securities laws generally prohibit the Bank from extending credit to its directors and executive officers. However, loans made by the Bank to its directors and executive officers in compliance with federal banking regulations are exempted from this prohibition. Federal banking regulations require that all loans or extensions of credit to directors and executive officers of insured institutions must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons and must not involve more than the normal risk of repayment or present other unfavorable features. The Bank, therefore, is prohibited from making any new loans or extensions of credit to directors and executive officers at different rates or terms than those offered to the general public.

All outstanding loans and commitments to date have been made in the ordinary course of business and on substantially the same terms, including with respect to interest rates and collateral, as for comparable transactions with unrelated persons, and have not involved more than the normal risk of repayment or presented other unfavorable features.

#### EXECUTIVE COMPENSATION

#### Compensation Philosophy and Objectives
This Executive Compensation section describes the 2025 executive compensation program for our named executive officers. Our primary objective is to achieve and sustain significant increases in shareholder value. We have designed our executive compensation program, and we routinely evaluate and consider modifications to the program, to support this objective with a strong link between pay and corporate and individual performance, while discouraging executives from taking excessive risks. Our approach is aimed at ensuring our ability to attract, retain and motivate the executives, managers and professionals who are critical to our short- and long-term success in the banking industry. A portion of our executives' compensation is "performance-based" in the form of incentives that are intended to motivate balanced decision-making by our executives while also aligning their interests with those of our shareholders.

We design our compensation program to align with the following principles:

• **Competitive.** We review the compensation practices of the other companies in our compensation peer group and aim to target compensation for our executives at or near the market 50% percentile.

• **Performance-based.** We use a mixture of options, time-based restricted stock and cash incentives to link our executives' compensation to Company short- and long-term performance. Our cash incentive program for 2025 used the following specific metrics to determine executive bonuses: consolidated pre-tax income, consolidated pre-tax return on average assets, consolidated pre-tax return on average tangible equity, net loan growth in indirect lending and a discretionary component related to each executive's contributions toward the Company's strategic goals during 2025.

• **Shareholder-aligned.** Our stock-based incentives encourage the creation of long-term value and link the interests of our executives to those of our shareholders.

• **Prudent risk-taking.** We structure our compensation program to incentivize sustainable growth without encouraging our executives to take unreasonable risks that could damage the Company's profitability or reputation.

#### Compensation Governance Best Practices
The Compensation Committee annually reviews best practices in executive compensation and governance and continues to enhance our policies and practices, which include the following:

#### Oversight of the Compensation Program
The Compensation Committee oversees our compensation program and approves the compensation paid to all executive officers, including the Chief Executive Officer and the two other most highly-compensated executive officers during 2025 – Mr. House, Mr. Elley and Mr. Mitchell (collectively, the "Named Executive Officers" or "NEOs").

Our Compensation Committee's responsibilities include reviewing and approving the amount, form and terms of compensation to be paid to the NEOs and assessing and making recommendations to the Board regarding executive compensation and benefit plans and programs. The Chief Executive Officer assists the Compensation Committee with determining the amount of compensation to be paid to the other executive officers but does not play a role in the final determination or approval of his own compensation. Our Human Resources Department also assists the Compensation Committee with compensation decisions by providing support and data for the committee.

#### Compensation Consultant
The charter of the Compensation Committee grants the Committee the authority to hire outside consultants to further its objectives and assist with its responsibilities. The Compensation Committee has engaged Willis Towers Watson, an independent compensation consultant, to assist the Compensation Committee by reviewing, assessing and providing recommendations with respect to the amount and form of director and executive officer compensation.

The Company does not have a policy that limits the services that an executive compensation consultant can perform. However, the Company has not engaged Willis Towers Watson for any projects other than those directed by the Compensation Committee and management, as described above, nor has Willis Towers Watson performed any other services for the Company. As a result, the Company has determined that Willis Towers Watson operates with full objectivity and without conflicts of interest in its support of the Compensation Committee.

#### Benchmarking
In determining market competitiveness of compensation, the Compensation Committee, with the assistance of Willis Towers Watson, reviews annually a combination of proxy information from the Company's compensation peer group and available market compensation survey data. The Compensation Committee may also use comparisons to the Company's compensation peer group to consider other market practices relevant to the scope of our executives' responsibilities. The Compensation Committee generally seeks to provide our executives with total compensation positioned around the median of competitive practice in order to assist in attracting and retaining talented executives and to further motivate and reward our NEOs for sustained, long-term improvements in the Company's financial results.

##### [**Table of Contents**](#toc)
At the request of the Compensation Committee, Willis Towers Watson prepared an evaluation of our peer group for use in 2025. As a result of the evaluation, Willis Towers Watson recommended, and the Compensation Committee approved, the fifteen companies listed below as the peer group for 2025. Willis Towers Watson identified and recommended these companies based on their being in a similar industry, being in a similar location and trading on the same stock exchange as the Company, as well as having assets between $800 million and $2 billion.

† Information as of July 31, 2025.

#### Elements of Executive Compensation

#### Base Salaries
Each NEO's base salary is determined principally by the responsibilities required by the officer's position, experience and contributions to our business and length of service in his position at the Company, as well as individual competence and comparison to peer institutions. Base salaries are reviewed and approved by the Compensation Committee annually to determine whether the base salary levels are appropriate. The base salaries of the NEOs in 2025 were as follows: for Mr. House, $412,000, increased from $400,000 in 2024; for Mr. Elley, $280,000, increased from $273,200 in 2024; and for Mr. Mitchell, $266,700, increased from $260,200 in 2024.

#### 2025 Cash Incentive Program
In February 2025, the Company established a cash incentive program for certain executive officers and key employees of the Company and its subsidiaries designed to incentivize the achievement of specified short-term performance criteria (the "2025 CIP"). Under the 2025 CIP, each NEO had the opportunity to earn a one-time cash payment equal to a predetermined percentage of his 2025 base salary, with the earned amount based on the level of performance with respect to certain corporate objectives applicable to the Company and the Bank. For Mr. House and Mr. Elley, the payment was based on (i) consolidated pre-tax income of the Company, (ii) consolidated pre-tax return on average assets, (iii) consolidated pre-tax return on average tangible equity, and (iv) a discretionary component related to each executive's contributions toward the Company's strategic goals during 2025. For Mr. Mitchell, the payment was based on (a) consolidated pre-tax income of the Company, (b) consolidated pre-tax return on average assets, (c) consolidated pre-tax return on average tangible equity, (d) net loan growth in indirect lending and (e) a discretionary component related to Mr. Mitchell's contributions toward the Company's strategic goals during 2025. The Company's 2025 performance targets are set forth in the table below.

---

Each NEO's cash incentive payment was potentially subject to a downward adjustment as a result of certain regulatory or compliance ratings at the Bank.

#### Equity Awards
Our named executive officers historically were eligible to participate in the First US Bancshares, Inc. 2013 Incentive Plan, which was originally adopted by the Board on March 22, 2013, and amended on May 2, 2019 (the "2013 Incentive Plan"). The 2013 Incentive Plan provided for the grant of incentive and nonqualified stock options, stock appreciation rights, awards of restricted stock and restricted stock units and performance compensation awards, including performance-based cash bonuses, to employees, non-employee directors and certain consultants of the Company and its affiliates, including the Bank.

On February 22, 2023, the Board adopted the First US Bancshares, Inc. 2023 Incentive Plan (the "2023 Incentive Plan"), which was approved by the Company's shareholders on April 27, 2023. The 2023 Incentive Plan provides for the grant of the same types of awards as the 2013 Incentive Plan. The Compensation Committee intends to grant all future incentive awards under the 2023 Incentive Plan, and no additional grants will be made under the 2013 Incentive Plan.

------

##### [**Table of Contents**](#toc)
On February 10, 2025, we granted equity awards to our NEOs in the following amounts: 6,500 shares of restricted stock for Mr. House, 3,300 shares of restricted stock for Mr. Elley and 3,200 shares of restricted stock for Mr. Mitchell. These shares of restricted stock vest in equal increments on the first three anniversaries of the grant date.

#### Equity Grant Practices
**Overview**. As discussed above, the Compensation Committee intends to continue to make regular grants of equity that incentivize performance and have retentive effect. All such equity awards will be made under the 2023 Incentive Plan. Our practice in granting equity is to determine the total number of shares to be granted under the 2023 Incentive Plan in a certain year based on the estimated expense to the Company of the awards and the earnings per share impact of that expense, as well as the total number of shares available for grant under the 2023 Incentive Plan. The Compensation Committee then allocates this pool of shares among the participants based on level and performance and considerations such as retention and competitive compensation levels. We do not select grant dates based upon the public release of material information about the Company, and the proximity of the grant date of any award to the date on which we announce such information is coincidental.

**Timing of Equity Grants**. We have not granted stock options as part of our equity compensation program since 2020, but the Compensation Committee may decide to do so again in the future. The Committee does not take into account material, non-public information in determining the timing and terms of equity-based awards, and we have not timed the disclosure of material, non-public information for the purposes of affecting the value of executive compensation. No stock options were issued to executive officers in 2025 during any period beginning four business days before the filing of a periodic report or current report disclosing material, non-public information and ending one business day after the filing or furnishing of such report with the SEC.

#### Termination and Change in Control Benefits
We believe that it is important to protect the financial interests of our senior management in the event of a change in control. Further, we believe that the interests of the Company's shareholders are best served if the interests of our senior management are aligned with the shareholders' interests. Providing change in control benefits should eliminate, or at least reduce, the reluctance of senior management to pursue potential change in control transactions that may be in the best interests of our shareholders.

Mr. House, our President and Chief Executive Officer, is the only NEO with an employment agreement. On December 19, 2013, the Company, the Bank and Mr. House entered into an Amended and Restated Executive Employment Agreement that replaced the original employment agreement entered into by the Company, the Bank and Mr. House on November 7, 2011, when Mr. House first began serving as the President and Chief Executive Officer of the Company and the Bank. In addition to setting forth various terms with respect to Mr. House's base salary, the equity compensation, perquisites and other benefits to which Mr. House is entitled, and certain restrictive covenants, the employment agreement contains certain termination and change in control provisions, the details of which are further discussed under the caption, "Employment Agreement with Mr. House."

Additionally, we have entered into a Change in Control Agreement with each of our executives, including Mr. Elley and Mr. Mitchell, pursuant to which certain payments are required in connection with a change in control. In the first quarter of 2022, we amended and restated the Change in Control Agreements for Mr. Elley and Mr. Mitchell. For more information, see "Potential Payments Upon Termination or Change in Control" contained herein.

#### Perquisites and Other Benefits
We provide our NEOs with limited perquisites and other personal benefits that we believe are reasonable and consistent with our overall compensation program to better enable us to attract and retain qualified senior

------

#### **Table of Contents**
management. We believe that perquisites for our executives should be limited in scope and value and also should reflect similar perquisites provided to executive officers at other banks of comparable size.

Perquisites provided include, in some cases, payment of cell phone fees, subscription radio fees and club dues, as well as a Company-owned automobile and reimbursement of reasonable expenses in operating such automobile, or in situations where a Company-owned automobile is not provided, an allowance to reimburse the NEO for the operation of a personal vehicle. Additionally, the Company pays a portion of the annual premium for a life insurance policy with a $250,000 death benefit for Mr. House. Effective December 2024, the Company also pays monthly premiums for a separate guaranteed-issue long-term disability policy for the NEOs, which would pay monthly amounts of $10,000, $9,210 and $8,195 for Mr. House, Mr. Elley and Mr. Mitchell, respectively, in the event of a coverage trigger. Otherwise, the NEOs participate in our employee benefit plans and programs on the same terms and conditions as other employees. The benefits available generally include medical and dental insurance, disability insurance and life insurance. In addition, we sponsor a 401(k) plan in which all eligible employees, including the NEOs, may participate.

#### Clawback/Recoupment Policy
We believe that the incorporation of a "clawback" or recoupment policy in our executive compensation program contributes to creating and maintaining a culture that emphasizes integrity and accountability and reinforces the performance-based principles underlying our executive compensation program. In November 2023, we adopted the First US Bancshares, Inc. Policy for the Recovery of Erroneously Awarded Compensation (the "Clawback Policy"), in compliance with the requirements of the Dodd-Frank Act, final SEC rules and applicable Nasdaq listing standards, which covers our current and former officers subject to Section 16 of the Exchange Act, including all of our NEOs. Under the Clawback Policy, if there is a restatement of our financial results, the Company will recover erroneously awarded incentive compensation from such officers during a three-year lookback period.

Additionally, our annual cash incentive programs permit recoupment of cash bonus payments in connection with certain events, including (i) achievement of financial results that are subsequently the subject of a restatement due to material noncompliance with any financial reporting requirement under either GAAP or the federal securities laws, other than as a result of changes to accounting rules and regulations, (ii) a subsequent finding that the financial information or performance objectives used by the Compensation Committee to determine the amount of any cash bonus payments were materially inaccurate and (iii) a Participant's conduct that is not in good faith and that materially disrupts, damages, impairs, or interferes with the business of the Company.

#### Insider Trading Policy; Prohibition on Pledging and Hedging of Company Stock and Equity Award Repricing
We are committed to promoting high standards of ethical business conduct and compliance with applicable laws, rules and regulations. As part of this commitment, we have adopted an Insider Trading Policy (the "Policy") governing all transactions in the Company's securities by the directors, officers and employees of the Company and any subsidiary that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the exchange listing standards applicable to us. A copy of the Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025.

The Policy prohibits the directors, officers and employees of the Company and any of its subsidiaries from pledging their common stock in the Company as collateral or engaging in transactions designed to "hedge" against the price of the Company's common stock. The Policy explicitly prohibits short sales and hedging or monetization transactions, including options trading (buying or selling puts or calls or other derivative securities). These restrictions ensure that the NEOs, as well as other Company personnel, cannot offset or hedge against declines in the price of the Company's common stock they own or have a personal interest in the price of their

------

#### **Table of Contents**
shares that may be different from the interests of other shareholders generally. None of the Company's directors or executive officers currently engage in any pledging or hedging transactions.

The Board of Directors and the Compensation Committee view equity-based compensation to be a key factor in incentivizing the future performance of our executives. Consequently, the 2023 Incentive Plan provides that the Compensation Committee is not permitted to reduce the exercise price of outstanding stock options or stock appreciation rights; replace any stock option or stock appreciation right with a new award with a lower exercise price; cancel any stock option or stock appreciation right in exchange for cash; or take any other action that would be treated as a repricing under the Nasdaq listing rules.

#### Consideration of Prior Shareholder Advisory Vote on Executive Compensation
We provide our shareholders with the opportunity annually to vote to approve, on an advisory basis, the compensation of our NEOs (often referred to as a "say-on-pay" vote). Although the "say-on-pay" vote is advisory and non-binding, the Compensation Committee considers the outcome of the vote as part of its executive compensation planning process. At the 2025 Annual Meeting of Shareholders held on May 1, 2025, approximately 96% of the shares represented at the meeting in person or by proxy and entitled to vote on the "say-on-pay" proposal (excluding broker non-votes) were voted in favor of the compensation of the Company's NEOs as disclosed in the proxy statement for that meeting. The Compensation Committee considered this high level of shareholder support when determining the compensation for 2026, and decided not to make any significant changes to the structure of our compensation program. The Compensation Committee concluded that the Company's compensation program should continue to emphasize the performance, alignment and retention objectives described herein.

#### Employment Agreement with Mr. House
On December 19, 2013, Mr. House entered into an Amended and Restated Executive Employment Agreement (the "2013 Employment Agreement") with the Company and the Bank, which became effective on January 1, 2014, and replaced the employment agreement entered into by Mr. House with the Company and the Bank on November 7, 2011, when Mr. House first began serving as President and Chief Executive Officer of the Company and the Bank.

The initial term of the 2013 Employment Agreement was three years, with an additional year added to the term on each anniversary of the effective date, unless one of the parties provides notice of its intention not to extend the term. The 2013 Employment Agreement provides that Mr. House will be paid and eligible for the following compensation, among other employee benefits: an annual base salary that is subject to increase by the Board, life insurance coverage in the amount of $250,000, the use of a Company-owned automobile and reimbursement of reasonable expenses in operating such automobile, temporary housing in Thomasville, Alabama, and reimbursement of ordinary and reasonable expenses incurred in the performance of his duties as Chief Executive Officer and President of the Company and the Bank. In addition, for each year of the term of the 2013 Employment Agreement, Mr. House will be eligible to receive an annual long-term incentive award of up to 5,000 shares of the Company's common stock, options to purchase up to 10,000 shares of the Company's common stock, or some combination of the foregoing. The agreement also contains non-compete and confidentiality restrictions. Specifically, Mr. House is prohibited from competing with the Company or the Bank for two (2) years following the termination of his employment and from disclosing confidential and proprietary information for a period of three (3) years after the termination of his employment.

Under the terms of the 2013 Employment Agreement, Mr. House is entitled to certain payments and benefits if his employment terminates due to his retirement, death or involuntary termination, or if his termination is related to a change in control of the Company or the Bank. In the event that Mr. House's employment terminates due to his death or disability, or Mr. House terminates his employment for any reason other than "good reason," he is entitled to any accrued and unpaid base salary earned through the date of termination and all vested amounts payable and vested benefits accrued under any otherwise applicable plan, policy, program or practice in which Mr. House was a participant. If Mr. House is involuntarily terminated without "cause" or Mr. House terminates his employment for "good reason," he is entitled to (i) a lump sum cash payment within thirty (30) days following his termination in an amount equal to the greater of either one (1) times his base salary then in effect or the amount of the base salary that otherwise would have been payable to Mr. House for the remainder of the term and (ii) reimbursement for any premiums paid by Mr. House for COBRA health continuation coverage, subject to limitations in the agreement. In the event of a change in control, Mr. House is not entitled to any payment unless he is terminated or he terminates his employment within six (6) months following the change in control. If Mr. House is terminated without "cause" or if he terminates his employment for "good reason" during the six (6) months following a change in control, he is entitled to a lump sum cash payment within thirty (30) days following his termination in an amount equal to 299% of his "base amount," as defined in Section 280G(b)(3)(A) of the Internal Revenue Code of 1986, as amended, subject to all applicable withholdings.

Internal Revenue Code Section 409A imposes significant taxes on an executive officer in the event that he receives deferred compensation that does not satisfy certain statutory and regulatory requirements in accordance with Internal Revenue Code Section 409A. However, it is the intent of the Company and the Bank that the amounts payable to Mr. House under the employment agreement comply with or are exempt from Section 409A.

#### Potential Payments Upon Termination or Change in Control
Mr. House's 2013 Employment Agreement contains severance provisions pursuant to which Mr. House is entitled to certain payments or benefits in the event that his employment is terminated without "cause" or for "good reason." See the discussion under "Employment Agreement with Mr. House" for additional information.

##### [**Table of Contents**](#toc)
In addition, on May 20, 2014, the Company entered into Change in Control Agreements with its executive officers, including Mr. Elley, and on February 22, 2021, the Company entered into an Amended and Restated Change in Control Agreement with Mr. Mitchell. Subsequently, on March 1, 2022, the Company entered into an Amended and Restated Change in Control Agreement with certain of its executive officers, including Mr. Elley, and a Second Amended and Restated Change in Control Agreement with Mr. Mitchell (collectively, the "Amended CIC Agreements"). Each of the Amended CIC Agreements provides for an eighteen-month period following a "change in control" (as defined in the Amended CIC Agreements) during which the executive officer will be, upon experiencing a "qualifying termination of employment" (as defined in the Amended CIC Agreements), entitled to a one-time lump sum payment by the Company in an amount equal to 200% of the sum of (A) the executive officer's annual base salary in effect as of the date of termination plus (B) the executive officer's target bonus opportunity under the cash incentive program in effect for the year at issue (the "Severance Benefit"), a pro rata share of the executive officer's target bonus for the year in which termination occurs, and the reimbursement by the Company of health insurance continuation expenses incurred by the executive officer, in addition to any rights and welfare benefits provided to the executive officer under any plans and programs upon termination of employment. In the event that the executive officer's employment is terminated as a result of such officer's voluntary resignation without "good reason" (as defined in the Amended CIC Agreements) within six (6) months after a change in control, the executive officer will be entitled to the same payments described above, except that the one-time lump sum payment will be equal to 100% of the executive officer's Severance Benefit. Each of the Amended CIC Agreements also provides that, during the employment period and for a period of two (2) years following termination of employment, the executive officer will be bound by covenants not to compete and not to solicit customers or employees; provided, however, that the non-competition provisions of the Amended CIC Agreements will apply only if the executive officer is entitled to the one-time lump sum payment described above; and, provided further, that if the executive officer is entitled to a lump sum payment equal to only 100% of the Severance Benefit, the non-competition provisions of the Amended CIC Agreements will endure for only one (1) year.

Pursuant to the restricted stock award agreements (each a "Restricted Stock Award Agreement") under the 2013 Incentive Plan and the 2023 Incentive Plan (collectively, the "Plans"), if an officer's Continuous Service (as defined in the Plans) terminates due to death, disability or retirement (as defined in the Restricted Stock Award Agreement), 100% of the unvested restricted stock shall vest as of the date of such termination. If the Continuous Service terminates for any reason other than death, disability or retirement, any unvested restricted stock shall be automatically forfeited upon such termination. Pursuant to the Plans, in the event of a Change in Control (as defined in the Plans) the Restricted Period (as defined in the Plans) shall expire immediately with respect to 100% of the shares of restricted stock, subject to the discretion of the Compensation Committee.

Pursuant to the nonqualified stock option agreements (each an "Option Agreement") under the Plans, in the case of termination due to disability, any unvested portion of the option shall become fully vested on the date of termination and the officer (or, in certain circumstances, his personal representative) may exercise the vested option at any time prior to the Expiration Date (as defined in the Option Agreement). In the case of termination due to death, any unvested portion of the option shall become fully vested on the date of death, and the vested option may be exercised by the officer's estate, by a person who acquired the right to exercise the option by bequest or inheritance, or by a person designated pursuant to the Option Agreement at any time prior to the Expiration Date. In the case of termination due to retirement (as defined in the Option Agreement), any unvested portion of the option shall become fully vested on the date of retirement and the officer may exercise the vested option at any time prior to the Expiration Date. In the case of termination other than for disability, death or retirement, the officer may exercise the vested portion of the option, but only within such period of time ending on the earlier of (a) the date three (3) months following the termination of the officer's continuous service or (b) the Expiration Date; provided, however, that in the case of termination for Cause (as defined in the Plans), the option (whether vested or unvested) shall immediately terminate and cease to be exercisable. In the case of a Change in Control, the option shall become immediately vested and exercisable with respect to 100% of the shares subject to the option, subject to the discretion of the Compensation Committee.

#### DIRECTOR COMPENSATION
In establishing director compensation, the Company considers the significant amount of time that directors expend in fulfilling their duties to the Company and the skill level required by the Company of members of the Board, as well as the importance of attracting and retaining qualified candidates to serve on the Board.

#### Fees
Each of the non-employee directors of the Company receives a $24,000 annual retainer for service as a director. If there is a non-executive Chairperson, he or she will receive an additional $10,000 annual retainer. If there is a Lead Independent Director, he or she will receive an additional $10,000 annual retainer. The Chairpersons of the committees of the Board receive additional retainer fees as follows: $7,500 annually for the Chairperson of the Audit Committee and $5,000 annually for the Chairperson of each of the following committees: the Asset/Liability Committee; the Compensation Committee; the Directors' Loan Committee; the Executive Committee; the Nominating and Corporate Governance Committee; the Information Technology Steering Committee; the Retail, Operations and Compliance Committee; and the Tennessee New Business Committee.

#### Equity Compensation
Our directors historically were eligible to participate in the 2013 Incentive Plan, under which they were able to receive grants of nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units and other types of equity awards designed to align the interests of the directors with those of the Company's shareholders. Pursuant to the First US Bancshares, Inc. Equity-Based Awards Grant Policy, the Compensation Committee determined the level of annual equity-based grants to be awarded with consideration given to each director's level of responsibility and total compensation as well as the value of any benefits to which a director is entitled under any retirement agreement with the Company, as discussed below.

On February 22, 2023, the Board adopted the 2023 Incentive Plan, which was approved by the Company's shareholders on April 27, 2023. The 2023 Incentive Plan provides for the grant of nonqualified stock, options, stock appreciation rights, restricted stock, restricted stock units and performance share awards.

On February 10, 2025, the Compensation Committee awarded a total of 13,050 shares of restricted stock to our directors. The shares vested in full on the first anniversary of the grant date and, therefore, are no longer restricted. During the restricted period, the directors were entitled to vote and receive dividends with respect to their shares of common stock but could not transfer the shares, outside of certain narrow exceptions. The value of the grant of restricted stock to each director is set forth in the "2025 Director Compensation Table" below.

#### Stock Ownership Guidelines for Non-Employee Directors
We believe that it is important for our directors to have a financial stake in the Company, and we have adopted formal stock ownership guidelines for non-employee directors. Under the ownership guidelines, which are set forth in our Guidelines on Significant Governance Issues, the Board has specified a requirement that non-employee directors must own at least 400 shares of the Company's common stock. The guidelines further direct that each non-employee director should develop a meaningful ownership position in the Company over time. During 2025, all of our non-employee directors were in compliance with the ownership guidelines. Additional information regarding the beneficial stock ownership of our non-employee directors can be found in the "Security Ownership of Certain Beneficial Owners and Management" table contained herein.

#### Director Retirement Agreements
In order to encourage the members of the Board to continue to serve as directors of the Company, we entered into director retirement agreements with each of our non-employee directors who joined the Board prior to 2013. The director retirement agreements are nonqualified deferred compensation arrangements that are designed to motivate the directors to serve on the Board until their retirement.

------

##### [**Table of Contents**](#toc)
We initially entered into the director retirement agreements in 2002 with each member of the Board at that time, including current directors Meigs and Wilson. In their original form, these agreements promised each director a benefit to be paid annually for ten years, generally beginning on the later of the date on which the director reached age 70 or the date on which the director terminated service as a director. The amount of the benefit was initially set at $12,000 in September 2002 and was scheduled to increase by 3% each year until the director reached age 70 or his or her service as a director was terminated. The benefit was to be reduced if the director retired from the Board before age 70 or terminated service as a director due to a disability before age 70.

The director retirement agreements provide a change in control benefit. We believe that the interests of the Company's shareholders will be best served if the interests of our directors are aligned with the shareholders' interests. Therefore, the director retirement agreements provide that, if a director is terminated following a change in control of the Company or a change in control of the Bank, we will pay the director annually for ten years, beginning at age 70, an amount equal to the maximum benefit that he or she would have been entitled to receive had the director terminated service as a director at age 70.

The director retirement agreements are subject to Internal Revenue Code Section 409A. On November 20, 2008, the Company and the Bank entered into amendments to the director retirement agreements for each director at the time, the purpose of which was to ensure that the terms of the director retirement agreements comply with Internal Revenue Code Section 409A so that the directors would avoid potential negative tax consequences. The amendments to the director retirement agreements did not materially change the scope or amount of benefits to which the directors are entitled but may affect the time and form of payment of such benefits. The director retirement agreement entered into by the director joining the Board subsequent to the November 2008 amendments but prior to 2013 (current director McPhearson) complies with Section 409A.

On January 25, 2017, the agreements with current directors Meigs and Wilson were again amended to reflect the increase in the mandatory retirement age for non-employee directors from age 70 to age 75. Specifically, the 2017 amendment clarified that the annual increases in the amount of the annual benefit payable pursuant to the agreement will terminate at the end of the plan year (commencing on September 1 and ending on August 31) immediately preceding the date of the first meeting of shareholders of the Company at which directors are elected, following the date on which the director reaches the mandatory retirement age set forth in the Company's Bylaws. No amendment was required to the agreement with current director McPhearson to reflect this clarification.

#### Equalization Stipend
Directors who joined the Board in 2013 or later have not entered into director retirement agreements. In order to alleviate pay discrepancies between directors who entered into director retirement agreements and those who did not, as well as to more equitably align the pay structure of all directors, beginning in 2021, an "equalization stipend" was paid in cash. This stipend served to fairly equalize the combination of all Board fees, stock awards, and changes in the accumulated benefit accruing under the director retirement agreements.

#### Deferral Plan
Non-employee directors may elect to defer payment of all or any portion of their fees earned as directors under the First US Bancshares, Inc. Non-Employee Directors' Deferred Compensation Plan (the "Deferral Plan"). The Deferral Plan, which was originally ratified at the Annual Meeting of the Company's shareholders held on May 11, 2004 and amended and restated by the Board effective July 1, 2023, permits non-employee directors to invest their directors' fees and to receive the adjusted value of the deferred amounts in cash and/or shares of the Company's common stock. If the deferred amounts are invested in share units, the return is determined as if such funds had been invested in the Company's common stock, and, if the deferred amounts are invested in cash, the return is calculated at an interest rate equal to the one-month term Secured Overnight Financing Rate (SOFR) plus 75 basis points. Deferred amounts generally are distributed to a director at the termination of such individual's service as a director of the Company, either in a lump sum payment or in annual

installment payments. During 2025, three of our non-employee directors (Messrs. Field, Hale and Miller) deferred some or all of their directors' fees under the Deferral Plan.

#### AUDIT COMMITTEE REPORT
The Audit Committee of the Board is composed of six directors who are independent directors as defined under the applicable Nasdaq listing rules and the SEC rules currently in effect.

The Audit Committee hereby submits the following report:

• We have reviewed and discussed with management the Company's audited consolidated financial statements as of and for the year ended December 31, 2025.

• We have discussed with the independent auditors, Carr, Riggs & Ingram, LLC, the matters required to be discussed with the independent auditors by applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the SEC.

• We have received the written disclosures and the letter from the independent auditors, Carr, Riggs & Ingram, LLC, required by applicable requirements of the PCAOB regarding Carr, Riggs & Ingram, LLC's communications with the Audit Committee concerning independence and have discussed with Carr, Riggs & Ingram, LLC its independence. We concluded that the provision of non-financial audit services was compatible with Carr, Riggs & Ingram, LLC's independence in performing financial audit services.

Based on the review and discussions referred to above, we recommended to the Board that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

It should be noted that management is responsible for the Company's financial reporting process, including its system of internal controls, and the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America. The Company's independent registered public accounting firm is responsible for auditing those consolidated financial statements. Our responsibility is to monitor and review this process. It is not our duty or our responsibility to conduct auditing or accounting reviews or procedures.

#### PROPOSAL 2

#### RATIFICATION OF APPOINTMENT OF

#### INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS
At the direction of the Audit Committee, the ratification of the appointment of Carr, Riggs & Ingram, LLC ("Carr, Riggs & Ingram") as the Company's independent registered public accountants for the year ending December 31, 2026, is being presented to the shareholders for approval at the Annual Meeting. Although ratification is not required by our Bylaws or otherwise, the Board is submitting the selection of Carr, Riggs & Ingram to our shareholders for ratification as a matter of good corporate governance. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another independent registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and our shareholders.

#### General
The Audit Committee has approved the engagement of Carr, Riggs & Ingram as the Company's independent registered public accountants for the year ending December 31, 2026. Carr, Riggs & Ingram has served as the Company's principal accountants since August 7, 2008.

The Audit Committee reviews our independent registered public accountants' performance and independence. In connection with the Audit Committee's selection of Carr, Riggs & Ingram as our independent registered public accountants for 2026, the Audit Committee considered and discussed, among other factors:

• Carr, Riggs & Ingram's current and historical performance on the Company's audit including the extent, timeliness and quality of communications with the Audit Committee and the Company's management;

• recent reports of the PCAOB's inspections of Carr, Riggs & Ingram;

• Carr, Riggs & Ingram's tenure as our independent registered public accountants and its familiarity with our operations, accounting policies and practices, and internal control over financial reporting;

• the Audit Committee's perception of, and Carr, Riggs & Ingram's statements regarding, the firm's independence;

• Carr, Riggs & Ingram's expertise in the banking industry and the Audit Committee's perception of its capability in handling issues related specifically to financial institutions;

• the knowledge and experience of the lead audit partner and other key members assigned to our audit service team;

• the appropriateness of Carr, Riggs & Ingram's fees and the reasonableness of the cost of the audit services; and

• consideration of the time and expense that would be incurred by management in order to onboard a new firm.

Carr, Riggs & Ingram's partners who are assigned as "lead audit partners" for its audits of public companies are subject to a mandatory rotation policy, and a partner in the firm may not serve as lead audit partner for the firm's audit of our financial statements for more than five consecutive years. The Audit Committee does not approve or disapprove the accounting firm's assignment of a particular partner as lead audit partner, or its assignment of other members of the firm to its audit team, for audits of our financial statements. However, in connection with the Audit Committee's selection of our independent registered public accountants each year, the Audit Committee meets with the proposed lead audit partner, considers the partner's experience and performance on previous audits and any experience of the Audit Committee with the partner, and seeks and considers the

------

##### [**Table of Contents**](#toc)
views of our executive management. The Audit Committee then communicates its views regarding that partner to management of the accounting firm.

Based on its evaluation, the Audit Committee believes that Carr, Riggs & Ingram is independent and that it is in our and our shareholders' best interests to retain Carr, Riggs & Ingram as our independent registered public accountants for 2026.

A representative from Carr, Riggs & Ingram is expected to attend the Annual Meeting, will have the opportunity to make a statement if he or she desires to do so and is expected to be available to respond to appropriate questions.

#### Pre-Approval Policies and Procedures
The Audit Committee of the Board has adopted policies and procedures for the pre-approval of audit and permissible non-audit services performed by the independent registered public accountants. Pursuant to these policies and procedures, the Audit Committee generally is required to pre-approve the audit and permissible non-audit services performed by the independent registered public accountants in order to assure that the provision of such services does not impair the auditor's independence. Unless a type of service to be provided by the independent registered public accountants has received general pre-approval, the service will require specific pre-approval by the Audit Committee. Any proposed services exceeding pre-approved cost levels will require specific pre-approval by the Audit Committee. On an annual basis, the Audit Committee may pre-approve specific services that are expected to be provided to the Company by the independent registered public accountants during the following twelve months.

#### Audit and Other Service Fees
The following table sets forth the aggregate fees billed to the Company for the audit and other services provided by Carr, Riggs & Ingram for 2025 and 2024.

#### PROPOSAL 3

#### ADVISORY APPROVAL OF EXECUTIVE COMPENSATION
The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010, requires that companies provide shareholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of their named executive officers in accordance with the compensation disclosure rules of the SEC. We intend to hold such an advisory vote on the compensation of our NEOs, commonly known as a "say-on-pay" vote, each year in connection with our annual meeting of shareholders until the next vote on the frequency of the "say-on-pay" vote or until the Board otherwise determines that a different frequency for this advisory vote is in the best interests of our shareholders. The next advisory vote on the frequency of future "say-on-pay" votes will occur no later than 2029.

As described in detail under the heading "Executive Compensation," we believe that the compensation of our executive officers should link rewards to business results and shareholders' returns. We believe that our compensation program should attract, retain and motivate the executive officers necessary for our current and long-term success and should provide the executive officers with a stake in the future of the Company that corresponds to the stake of each of our shareholders.

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our NEOs, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC. The vote is advisory, which means that the vote is not binding on the Company, the Board or the Compensation Committee of the Board. To the extent that there is any significant vote against our NEO compensation as disclosed in this Proxy Statement, the Compensation Committee will evaluate whether any actions are necessary to address the concerns of shareholders.

The affirmative vote of a majority of the shares represented at the Annual Meeting in person or by proxy and entitled to vote on this matter is required for the adoption of this Proposal, the results of which will be non-binding and advisory in nature.

Accordingly, pursuant to Section 14A of the Exchange Act, we ask our shareholders to vote on the following resolution at the Annual Meeting:

"RESOLVED, that the Company's shareholders approve, on an advisory basis, the compensation of the NEOs, as disclosed in the Company's Proxy Statement for the 2026 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the SEC, including the 'Executive Compensation' section, the 'Summary Compensation Table' and the other related tables and disclosure."

#### THE BOARD RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF THE COMPENSATION OF OUR NEOS, AS DISCLOSED IN THIS PROXY STATEMENT.

#### SHAREHOLDER PROPOSALS FOR 2027 ANNUAL MEETING
If any shareholder wishes to present a proposal to be included in the proxy materials for the Company's 2027 Annual Meeting of Shareholders, the shareholder must comply with applicable securities regulations, including providing adequate notice to the Company. Such proposals must be received by the Company at the address noted below on or before November 18, 2026, in order to be considered for inclusion in the Company's proxy materials relating to such meeting. If the date of the 2027 Annual Meeting changes by more than 30 days from April 30, 2027, then the deadline to submit stockholder proposals for inclusion in the proxy statement for the 2027 Annual Meeting will be a reasonable time before the Company begins to print and mail its proxy materials for the 2027 Annual Meeting. The Company will determine whether to include a proposal in the 2027 proxy statement in accordance with the SEC rules governing the solicitation of proxies.

If a stockholder proposal is submitted outside the proposal process mandated by SEC Rule 14a-8, and is submitted instead under the Company's advance notice Bylaw provision (Section 2.15 of the Bylaws), the proposal must be received by the Company's Corporate Secretary not earlier than December 31, 2026 nor later than January 30, 2027, together with the necessary supporting documentation required under that Bylaw provision. If the date of the 2027 Annual Meeting is advanced by more than 30 days or is delayed by more than 60 days from April 30, 2027, then to be timely the nomination or proposal must be received by the Company no earlier than the 120<sup>th</sup> day prior to the 2027 Annual Meeting and no later than the close of business on the later of the 90<sup>th</sup> day prior to the meeting or the 10<sup>th</sup> day following the day on which public announcement of the date of the 2027 Annual Meeting is first made.

In addition to satisfying the requirements under our Bylaws, to comply with the SEC's universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company's nominees at the 2027 Annual Meeting must provide notice to the Company that complies with the informational requirements of Rule 14a-19 under the Exchange Act.

Any proposal must be submitted in writing, by certified mail, return receipt requested, to:

Post Office Box 249

Thomasville, Alabama 36784

#### OTHER MATTERS
We do not know of any matters to be presented for action at the Annual Meeting other than those set forth in the notice of the Annual Meeting and discussed in this Proxy Statement.

SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements and notices with respect to two or more shareholders sharing the same address by delivering a single proxy statement or a single notice addressed to those shareholders. Each shareholder continues to receive a separate proxy card. This process, commonly referred to as "householding," provides cost savings for companies. Some brokers household proxy materials, delivering a single proxy statement or notice to multiple shareholders sharing an address, unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement or notice, please notify your broker.
