Sincerely,
Gary E. Kramer
President and Chief Executive Officer

## NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

June 1, 2026

You are invited to attend the virtual annual meeting of stockholders (the "Annual Meeting") of Barrett Business Services, Inc., a Maryland corporation (the "Company"), to be held solely by remote communication via live webcast on Monday, June 1, 2026, at 1:00 p.m., Pacific Time. You may attend the live webcast on the internet by visiting https://www.virtualshareholdermeeting.com/BBSI2026. To access the webcast, go to this website and follow the instructions provided.

The Annual Meeting is being held to consider and vote on the following matters:

1.
Election of nine directors to serve until the 2027 annual meeting of stockholders;
2.
Approval of the Barrett Business Services, Inc. Second Amended and Restated 2020 Stock Incentive Plan to increase the maximum number of shares of the Company’s common stock for which awards may be granted under the Plan;
3.
Advisory vote to approve the compensation of our named executive officers;
4.
Ratification of the selection of Deloitte & Touche LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2026; and
5.
The transaction of any other business that may properly come before the Annual Meeting and any postponement or adjournment thereof.

If you were a stockholder of record or beneficial owner at the close of business on April 6, 2026, you may vote on the proposals presented at the Annual Meeting. On or about April 22, 2026, we expect to mail to our stockholders of record and beneficial owners a Notice of Internet Availability of Proxy Materials (the "Notice"), unless they have elected to receive the materials in a different manner. The Notice provides instructions on how to access and review all of the important information contained in the Proxy Statement and Annual Report to Stockholders. Please follow the instructions in the Notice to vote your proxy. If you receive the Notice and would still like to receive a printed copy of our proxy materials by mail, instructions for requesting these materials are included in the Notice. Additionally, the Proxy Statement and our Annual Report can be accessed directly at the following Internet address: http://www.proxyvote.com.

Whether or not you plan to attend the virtual Annual Meeting, please vote your shares via the Internet, by telephone, or by signing, dating, and returning the proxy card or voting instruction form, to avoid the expense of further solicitation. If you attend the Annual Meeting virtually, you may revoke your proxy and vote your shares at that time. Please refer to the Notice, Proxy Statement, or the information forwarded by your broker or other nominee to see which voting methods are available to you.

By Order of the Board of Directors
James R. Potts
Secretary

Vancouver, Washington

April 20, 2026

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE STOCKHOLDER MEETING TO BE HELD ON JUNE 1, 2026:

Notice of Internet Availability of Proxy Materials

Under the "notice and access" rules of the Securities and Exchange Commission (the "SEC"), we are able to provide access to our proxy materials, including our proxy statement for the 2026 annual meeting of stockholders and 2025 annual report to stockholders, through the Internet by mailing a Notice of Internet Availability of Proxy Materials (the "Notice") to our stockholders. Our Board of Directors is soliciting your proxy to vote at our Annual Meeting, including at any adjournments or postponements of the meeting. The Notice includes instructions on how to access our proxy materials over the Internet or to request a printed copy.

We expect the Notice will be mailed to our stockholders entitled to vote at our Annual Meeting on or about April 22, 2026.

Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for the Notice or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are stockholders in the Company will be householding our proxy materials. A single Notice will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. Stockholders who hold their shares in "street name" (that is, through a broker or other nominee) and currently receive multiple copies of the Notice at their address and would like to request householding of their communications should contact their broker.

If your shares are registered in your own name and if you no longer wish to participate in householding and would prefer to receive a separate Notice, please direct your written request to Equiniti Trust Company, LLC ("Equiniti"), Attn: Proxy Tabulation Department, 55 Challenger Rd. Suite 200B 2nd floor, Ridgefield Park, NJ 07660, or you may reach Equiniti by telephone at 800-937-5449. If your shares are registered in your own name and you are interested in participating in householding, you may enroll by going directly to the Equiniti website anytime, at https://equiniti.com/us/ast-access and following the instructions.

## PROXY STATEMENT

2026 ANNUAL MEETING OF STOCKHOLDERS

This proxy statement is furnished in connection with the solicitation of proxies by the Board of Directors (the "Board") of Barrett Business Services, Inc., a Maryland corporation (the "Company"), for use in voting at the annual meeting of stockholders to be held on June 1, 2026 (the "Annual Meeting"), and any postponement or adjournment thereof. Notices are expected to be mailed to stockholders beginning on approximately April 22, 2026. Website references throughout this document are provided for convenience only, and the content on the referenced website is not incorporated by reference into this document.

VOTING, REVOCATION, AND SOLICITATION OF PROXIES

This year’s Annual Meeting will again be held as a virtual meeting of stockholders conducted online solely by remote communication via live webcast. You will be able to attend and participate in the Annual Meeting online on Monday, June 1, 2026, at 1:00 p.m. Pacific Time, and may also vote your shares electronically (by following the procedures described below) and submit any questions you may have during the meeting, by visiting: www.virtualshareholdermeeting.com/BBSI2026.

When a proxy is properly voted and submitted via the Internet or by telephone, or executed and mailed in the accompanying postage prepaid envelope for those receiving paper copies, the shares represented will be voted at the Annual Meeting in accordance with the instructions specified in the proxy. We encourage you to submit your proxy promptly, by following the instructions on the Notice, or by mail for paper proxy cards, even if you plan to attend the Annual Meeting. If no voting instructions are specified on a properly submitted proxy, the shares will be voted FOR Proposals 1, 2, 3, and 4 in the Notice of Annual Meeting of Stockholders accompanying this proxy statement.

Voting Your Shares Now or at the Annual Meeting. To vote now, follow the instructions on the Notice or on your proxy card or voting instruction form. If you are a record holder, you may vote your shares at the Annual Meeting if you log in with your unique control number on your Notice or proxy card.

If you are a beneficial owner and do not provide specific voting instructions to your broker, the firm that holds your shares will not be authorized to vote your shares (known as a "broker non-vote") on non-routine matters under the New York Stock Exchange rules governing discretionary voting by brokers. As of the date of this proxy statement, we believe that Proposals 1, 2, and 3 will be non-routine, but that Proposal 4 will be deemed to be routine, such that brokers will be able to vote on Proposal 4 without customer instructions.

You are entitled to participate in the Annual Meeting if you were a shareholder as of the close of business on April 6, 2026, the record date, or hold a valid proxy for the meeting. To be admitted to the Annual Meeting at https://www.virtualshareholdermeeting.com/BBSI2026, you must enter the 16-digit Control Number found next to the label “Control Number” on your Notice of Internet Availability, proxy card, or voting instruction form, or in the email sending you the Proxy Statement. If you are a beneficial owner, you may contact the bank, broker, or other institution where you hold your account if you have questions about obtaining your Control Number.

Any proxy given pursuant to this solicitation may be revoked by the person giving the proxy at any time prior to its exercise by written notice to the Secretary of the Company of such revocation, by a later-dated proxy received by the Company, or by attending and voting at the Annual Meeting. The mailing address of the Company’s principal executive offices is 8100 NE Parkway Drive, Suite 200, Vancouver, Washington 98662. If your shares are held through a broker or other nominee, please follow their directions on how to change or revoke your voting instructions.

- 1 -

The solicitation of proxies will be made by mail and may also be solicited personally or by telephone or email by our directors and officers without additional compensation for such services. The Company will reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for their reasonable expenses in sending proxy materials to stockholders. All costs of solicitation of proxies will be borne by the Company.

OUTSTANDING VOTING SECURITIES

The close of business on April 6, 2026, has been fixed as the record date for the determination of stockholders entitled to notice of and to vote at the Annual Meeting. On the record date, the Company had 24,559,649 shares of Common Stock, $.01 par value ("Common Stock"), outstanding. Each share of Common Stock is entitled to one vote at the Annual Meeting. The presence, in person or by proxy, of stockholders entitled to cast a majority of all votes entitled to be cast at the Annual Meeting is required to constitute a quorum. Abstentions and broker non-votes, if any, will be considered present for purposes of determining the presence of a quorum.

- 2 -

## PROPOSAL 1: ELECTION OF DIRECTORS

The director nominees will be elected at the Annual Meeting to serve until the next annual meeting of stockholders and until their successors are elected and qualify. Our Charter and Bylaws authorize the Board to set the number of positions on the Board within a range of three to nine, with the current number fixed at nine. Vacancies on the Board, including vacancies resulting from an increase in the number of positions, may be filled by the Board for a term ending with the next annual meeting of stockholders and when a successor is duly elected and qualifies.

Provided that a quorum is present at the Annual Meeting, a nominee will be elected if the nominee receives the affirmative vote of a majority of the total votes cast on his or her election (that is, the number of shares voted "for" a director nominee must exceed the number of votes cast "against" that nominee). All of our director nominees are currently serving on the Board. Even if a nominee who is currently serving as a director is not re-elected, Maryland law provides that the director would continue to serve on the Board as a "holdover director." However, under our Bylaws, if stockholders do not re-elect a director, the director is required to submit his or her resignation to the Board. In that event, our Nominating and Governance Committee (the "Nominating Committee") would recommend to the Board whether to accept or reject the resignation. The Board would then consider and act on the Nominating Committee's recommendation, publicly disclosing its decision and the reasons supporting it within 90 days following the date that the resignation was submitted.

A duly executed proxy will be voted FOR the election of the nominees named below, other than proxies marked to vote "against" or to "abstain" from voting on one or more nominees. Shares not represented in person or by proxy at the Annual Meeting, shares voted to "abstain," and broker non-votes, if any, will have no effect on the outcome of the election of directors.

The Board recommends that stockholders vote FOR each of the nominees named below to serve as a director until the next annual meeting of stockholders and his or her successor is duly elected and qualifies. If for some unforeseen reason a nominee should become unavailable for election, the proxy may be voted for the election of such substitute nominee as may be designated by the Board.

The following table sets forth information with respect to each person nominated for election as a director, including their current principal occupation or employment and age as of April 1, 2026.

Name |  | Principal Occupation |  | Age |  | Director Since
Thomas J. Carley |  | Retired Chief Operating Officer of Urth Organic Corporation |  | 67 |  | 2000
Joseph S. Clabby |  | Retired Vice President at Chubb Limited |  | 72 |  | 2022
Thomas B. Cusick |  | Retired Chief Financial Officer of Columbia Sportswear Company |  | 58 |  | 2016
Mark S. Finn |  | Retired Portfolio Manager at T. Rowe Price Group |  | 63 |  | 2025
Gary E. Kramer |  | President and Chief Executive Officer of the Company |  | 46 |  | 2020
Anthony Meeker |  | Retired Managing Director of Victory Capital Management, Inc., Cleveland, Ohio |  | 87 |  | 1993
Carla A. Moradi |  | Board member of the Company, Patriot Growth Insurance Services, LLC, American Residential Services, and Lightedge Solutions, Inc. |  | 61 |  | 2021

Carley, Clabby, Cusick, Finn, Meeker and Price are independent directors as defined in Rule 5605(a)(2) of the listing standards applicable to companies listed on Nasdaq. In making that determination, the Board took into consideration certain business relationships that the Company has with entities of which BBSI directors are associated as directors or employees, as follows:

•
Ms. Moradi is a member of the board of directors of Patriot Growth Insurance Services, LLC, a privately held insurance services firm. Patriot Growth owns multiple insurance brokerages, some of which are or have been referral partners for the Company.
•
Mr. Price was an executive officer of Cambia until October 2023 and continues to serve as an advisor to Cambia’s Chief Executive Officer. Cambia, which is the ultimate parent company of Healthcare Management Administrators ("HMA," which also does business as "Regence Group Administrators" or "RGA"), provides certain third-party administrator services to self-insured health plans for employers in Washington, Oregon, Utah, and Idaho, including the Company. In addition, in 2022, the Company announced the launch of a fully insured health and welfare benefits offering for its professional employer services clients. Cambia’s affiliated insurance companies offer health plans that compete with the plans the Company is offering its clients in certain markets. With regard to the Company's plan offerings in the state of Idaho, in 2023, the Company entered into an arrangement with Regence BlueShield of Idaho, an Idaho nonprofit mutual insurance company, to provide certain health insurance benefits and other services to the Company's clients in Idaho. Cambia provides administrative services to Regence BlueShield of Idaho.

BOARD GOVERNANCE AND COMMITTEES

Board Leadership Structure

Gary E. Kramer was appointed the Company’s Chief Executive Officer on March 5, 2020, and became a director on May 27, 2020. Joseph S. Clabby serves as Chairman of the Board and is an ex officio member of each Board committee of which he is not a voting member. Mr. Clabby has served as a outside director of the Company since September 16, 2022 and was Vice Chairman of the Board from December 13, 2024 to June 2, 2025. On June 2, 2025, Mr. Clabby was appointed Chairman of the Board. He succeeded Anthony Meeker, who served as Chairman of the Board from January 20, 2011 to June 2, 2025. Mr. Meeker continues to serve as a member of the Board.

Throughout 2025, each of our then directors, other than Mr. Kramer, qualified as an independent director under the Nasdaq listing rules. The outside directors also meet at least two times per year in executive session without the President and Chief Executive Officer or other management being present.

The Board believes that its longstanding leadership structure reflecting the separation of the Chairman and Chief Executive Officer positions serves the best interests of the Company by giving an independent director a direct and significant role in establishing priorities and the strategic direction and oversight of the Company. As part of its role in risk oversight, the Board has determined that this leadership structure continues to be appropriate and effective.

The Board’s Role in Risk Oversight

The Company's management is responsible for identifying, assessing, and managing the material risks facing the Company. The Board has historically performed an important role in the review and oversight of risk, and generally oversees risk management practices and processes at the Company. The Board, either as a whole or through the Audit and Compliance Committee (the "Audit Committee"), the Risk Management Committee, and other Board committees, periodically discusses with management the risks associated with the Company and its operations, their potential impact on the Company, and the steps being taken to manage these risks.

While the Board is ultimately responsible for risk oversight, the Board's committees assist the Board in fulfilling its oversight responsibilities in certain areas of risk. In particular, the Audit Committee focuses on financial risk and, through discussions by the Audit Committee or its Chair with management and the Company’s independent registered public accounting firm (the "independent auditors"), oversees the Company's policies, practices, and internal controls related to the preparation of the Company's financial statements and other public disclosures. The Audit Committee also reviews the Company’s major financial risk exposures and the steps management is taking to monitor and control such risks.

The Nominating Committee oversees the functioning of the Board and its committees, issues and developments relating to the Company's corporate governance practices, succession planning for the Board and the Company's executive positions, and the Company’s ethics and compliance program (other than with regard to issues assigned to the Audit Committee). The Compensation Committee monitors the Company's incentive compensation programs to assure that management is not encouraged to take actions involving excessive risk. The Risk Management Committee provides oversight of the Company's enterprise-wide risk management framework and corporate risk function, including the strategies, policies, procedures, processes, and systems established by management to identify, assess, measure, monitor, and manage the major risks facing the Company, other than risks for which responsibility has been assigned to a different Board committee.

Board Meetings

The Board held seven meetings in 2025. Each director attended 100% of the total number of the meetings of the Board and the meetings held by each committee of the Board on which he or she served during his or her respective periods of service in 2025.

The Company does not have a policy regarding directors' attendance at the Company's annual meeting of stockholders. All directors in office as of last year's annual meeting attended the meeting.

Board Committees

Audit and Compliance Committee

The Audit Committee reviews and pre-approves audit and legally permitted non-audit services provided by the independent auditors, makes decisions concerning the engagement or discharge of the independent auditors, and reviews with management and the independent auditors the results of their audit, the adequacy of internal accounting controls and the Company’s internal audit function, and the quality of the Company’s financial reporting. The Audit Committee also oversees implementation of the Company's Code of Business Conduct and Code of Ethics for Senior Financial Officers, including procedures for the receipt, retention, and treatment of complaints received regarding accounting, internal accounting controls, or auditing matters. The Audit Committee reviews for potential conflicts of interest, and determines whether to approve, any transaction by the Company with a director or officer (including their family members) that would be required to be disclosed in the Company's annual proxy statement. The Audit Committee held five meetings in 2025.

The current members of the Audit Committee are Mr. Cusick (chair), Mr. Carley, Mr. Finn, and Mr. Meeker. The Board has determined that Mr. Cusick is qualified to be an "audit committee financial expert" as defined by the SEC's rules under the Securities Exchange Act of 1934 (the “Exchange Act”). The Board has also determined that each current member of the Audit Committee meets the financial literacy and independence requirements for audit committee membership specified in applicable SEC rules and in listing standards applicable to companies listed on Nasdaq. The Audit Committee's activities are governed by a written charter, a copy of which is available on the Company's website at www.BBSI.com in the "Investors" section under "Governance."

- 7 -

Compensation Committee

The Compensation Committee is responsible for reviewing and approving the compensation of executive officers of the Company, including base salaries, incentive compensation and restricted stock units ("RSUs") and other stock-based awards. The current members of the Compensation Committee are Mr. Price (chair), Mr. Cusick, Ms. Moradi, and Ms. Morehouse, each of whom is "independent" as defined in Rule 5605(a)(2) and Rule 5605(d)(2)(A) of the listing standards for companies listed on Nasdaq. The Compensation Committee held eight meetings in 2025.

The Compensation Committee's responsibilities are outlined in a written charter, a copy of which is available on the Company's website at www.BBSI.com in the "Investors" section under "Governance." The Compensation Committee is charged with carrying out the Board's overall responsibilities relating to compensation of the Company's executive officers and non-employee directors. Its specific duties include reviewing the Company's cash incentive and equity compensation programs for executive officers and director compensation arrangements, and recommending changes to the Board as it deems appropriate. In the course of reviewing the Company's compensation policies and practices, the Compensation Committee considers whether the Company's compensation program encourages employees to take risks that are reasonably likely to have a material adverse effect on the Company. Based on its most recent review in April 2026, the Compensation Committee believes that the Company's compensation program is not likely to have that effect.

The Chief Executive Officer reviews the performance of each executive officer (other than himself) and may make recommendations to the Compensation Committee regarding salary adjustments, stock-based awards, and the selection, target amounts and satisfaction of corporate and individual performance goals for cash and stock incentive awards. The Compensation Committee is responsible for annually evaluating the CEO's performance and establishing his base salary and incentive compensation. At the invitation of the Committee chair, either or both of the Company's Chief Executive Officer and Chief Financial Officer may attend Compensation Committee meetings to provide information relevant to the Committee's determination of the satisfaction of corporate performance goals tied to cash and stock incentive compensation and the development of appropriate corporate performance targets for future awards of incentive compensation, as well as financial and accounting issues associated with the Company's executive compensation program. The Compensation Committee exercises its own discretion in accepting or modifying the CEO's recommendations regarding the performance and compensation of the Company's other executive officers. If present at a Compensation Committee meeting, each of the CEO and CFO is excused during discussions of his compensation.

The Compensation Committee also administers the Company's stock incentive plans. The Compensation Committee, as it deems appropriate and as permitted by applicable law, may delegate its responsibilities to a subcommittee under the Company's 2020 Stock Incentive Plan (as it has been or may be further amended, the "2020 Stock Plan"). The Compensation Committee has delegated authority, within specified limits, to the CEO (provided he is also a director) to make stock-based awards in his discretion to corporate and branch personnel who are not executive officers.

Under its charter, the Compensation Committee has the sole authority to retain the services of outside consultants to assist it in making decisions regarding executive compensation and other compensation matters for which it is responsible. For the past several years, the Compensation Committee has engaged Mercer, a nationally recognized compensation consultant, to assist the Committee in structuring and implementing the Company's executive compensation program. The Compensation Committee received information from Mercer regarding any potential conflicts of interest prior to each engagement and determined that no conflicts existed. The Compensation Committee engages Mercer to assist the committee in refreshing the Company’s compensation peer group every three years; the most recent update occurred in 2024, as discussed in more detail under the heading “Compensation Discussion and Analysis” below. The Compensation Committee also asked Mercer to advise the committee on executive pay trends and the market competitiveness of its executive and director compensation programs in October 2025.

Nominating and Governance Committee

The Nominating Committee evaluates and recommends candidates for nomination by the Board in director elections and otherwise assists the Board in determining the composition of the Board and its committees, including evaluating matters related to diversity and the performance of the Board and its members. The Nominating Committee is also responsible for reviewing issues and developments in corporate governance and considering whether to recommend changes in the Company’s corporate governance framework, overseeing succession planning with respect to the Company's executive officers, and overseeing the Company’s ethics and compliance program (other than issues related to accounting and financial reporting or within the responsibilities assigned to the Audit Committee). The current members of the Nominating Committee are Mr. Carley (chair), Mr. Clabby, Mr. Meeker, and Ms. Morehouse. The Nominating Committee held two meetings in 2025.

- 8 -

The Board has determined that each current member of the Nominating Committee is an independent director as defined in Rule 5605(a)(2) of the listing standards applicable to companies listed on Nasdaq. The Nominating Committee is governed by a written charter, which is available on the Company's website at www.BBSI.com in the "Investors" section under "Governance."

The Nominating Committee does not have any specific, minimum qualifications for director candidates. In evaluating potential director nominees, the Nominating Committee will consider, among other factors:

•
The candidate’s ability to commit sufficient time to the position;
•
Professional and educational background that is relevant to the financial, regulatory, industry and business environment in which the Company operates;
•
Demonstration of ethical behavior;
•
Whether the candidate contributes to the goal of bringing diverse perspectives, business experience, and expertise to the Board; and
•
The need to satisfy independence and financial expertise requirements relating to Board and committee composition.

While the Board has not adopted a formal policy with respect to the consideration of diversity in identifying director nominees, the Nominating Committee believes it is important that the Board as a whole represent a diversity of backgrounds and experience, including gender and ethnic background. Accordingly, the Nominating Committee has committed to continue its search for diverse candidates to include in the pool from which future Board members will be chosen.

The Nominating Committee relies on its periodic evaluations of the Board in determining whether to recommend nomination of current directors for re-election. The Nominating Committee periodically polls current directors for suggested candidates and also may engage an executive search firm when called upon to identify new director candidates.

The Nominating Committee will also consider director candidates suggested by stockholders for nomination by the Board. Stockholders wishing to suggest a candidate to the Nominating Committee should do so by sending the candidate’s name, biographical information, and qualifications to: Nominating Committee Chair c/o Corporate Secretary, Barrett Business Services, Inc., 8100 NE Parkway Drive, Suite 200, Vancouver, Washington 98662. Candidates suggested by stockholders will be evaluated by the same criteria and process as candidates from other sources.

Risk Management Committee

The Risk Management Committee reviews and discusses with management the development and performance of the Company’s enterprise risk management program, investment guidelines for the Company’s investment portfolios, the Company’s insurance and risk management programs, and technology risks facing the Company, including information security and cyber defense mechanisms. The Risk Management Committee held four meetings in 2025. Its current members are Ms. Moradi (chair), Mr. Clabby, Mr. Finn, and Mr. Price. The Risk Management Committee is governed by a written charter, which is available on the Company's website at www.BBSI.com in the "Investors" section under "Governance."

The Company also has adopted a Code of Business Conduct, which is generally applicable to all of the Company's directors, officers, and employees. Both the Code of Ethics and the Code of Business Conduct are available on the Company's website at www.BBSI.com in the "Investors" section under "Governance."

Anti-Hedging Policy and Insider Trading Policy

The Company has adopted an Anti-Hedging Policy, which prohibits the Company’s directors and executive officers from directly or indirectly engaging in hedging against future declines in the market value of any Company securities through the purchase of financial instruments designed to offset such risk. Executive officers and directors who fail to comply with the policy are subject to Company-imposed sanctions, which may include a demotion in position, reduced compensation, restrictions on future participation in cash or stock incentive plans, or termination of employment. The Company’s Anti-Hedging Policy is available on the Company’s website at www.BBSI.com in the "Investors" section under "Governance."

The Company has also adopted an Insider Trading Policy that applies to directors, executive officers, and other employees, as well as family members as defined in the policy.

- 12 -

Stock Ownership Guidelines for Non-Employee Directors and Executive Officers

The Board has adopted stock ownership guidelines such that each non-employee director is expected to own shares of Common Stock with a value equal to at least three times the regular annual cash retainer ($70,000 effective January 1, 2025), within three years of first being elected. The value of shares owned is calculated quarterly based on the higher of current market price or the average daily closing price for the preceding 12 months. Any shortfall resulting from an increase in the annual cash retainer or a decrease in the stock trading price (or both) is expected to be cured within two years following the end of the quarter in which the resulting required increase in share ownership first occurred.

The Board also adopted a policy on stock ownership for the Company's executive officers. Under the policy, executive officers have until July 1, 2021, or five years after the date the executive officer is notified of his or her appointment, whichever is later, to achieve and maintain ownership of shares of Common Stock and unvested RSUs with a value equal to at least three times the officer's annual base salary. Shares will be valued at the greater of the then current market price and the original purchase price. RSUs will be valued at the greater of the then current market price and the original grant price. Until the minimum ownership level is reached, the officer is expected to retain at least 50% of the shares of Common Stock received upon exercise of an option or vesting of RSUs and performance shares, after payment of the exercise price and withholding and payroll taxes. Participants who are not in compliance will not be permitted to sell or dispose of shares, except as described in the preceding sentence, until they reach the required ownership level. The Nominating Committee may make an exception in its sole discretion in the case of financial hardship.

All non-employee directors and all executive officers have met the guidelines or are on track to meet the guidelines within the required timeframe.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16 of the Exchange Act requires that reports of beneficial ownership of Common Stock and changes in such ownership be filed with the SEC by Section 16 "reporting persons," including directors, executive officers, and certain holders of more than 10% of the outstanding Common Stock. To the Company's knowledge, based solely on a review of the copies of Forms 3, 4, and 5 (and amendments thereto) filed with the SEC and written representations by the Company's directors and executive officers, all Section 16 reporting persons complied with all applicable Section 16(a) filing requirements during 2025 on a timely basis.

## PROPOSAL 2: APPROVAL OF THE BARRETT BUSINESS SERVICES, INC. SECOND AMENDED AND RESTATED 2020 STOCK INCENTIVE PLAN

The Barrett Business Services, Inc. 2020 Stock Incentive Plan was initially approved by the stockholders on May 27, 2020, and became effective on that date. The stockholders approved the first amendment and restatement of the 2020 Stock Plan on June 5, 2023, which became effective on that date. The primary purpose of the first amendment to the 2020 Stock Plan was to increase the number of shares of Common Stock available for awards from 1,500,000 to 2,900,000, while the maximum number of shares of Common Stock that may be granted as incentive stock options (“ISOs”) remained at 1,500,000.

We are asking our stockholders to approve the second amendment and restatement of the 2020 Stock Plan (the “Second Amended and Restated 2020 Stock Plan”). Upon the recommendation of the Compensation Committee, the Board approved the Second Amended and Restated 2020 Stock Plan on April 3, 2026, subject to the approval of the stockholders at the 2026 Annual Meeting. The proposed increase will take effect only if the stockholders approve the Second Amended and Restated 2020 Stock Plan by the required vote at the Annual Meeting. By approving the Second Amended and Restated 2020 Stock Plan, the stockholders will also be reapproving the other existing material terms of the 2020 Stock Plan. A copy of the Second Amended and Restated 2020 Stock Plan as proposed to be amended is attached to this proxy statement as Appendix A, and the following description of the Second Amended and Restated 2020 Stock Plan is qualified in its entirety by reference to Appendix A.

Purposes and Effects of the Second Amended and Restated 2020 Stock Plan

The Board has submitted Proposal 2 for approval primarily to increase the number of shares of Common Stock available for awards. If Proposal 2 is approved, the maximum number of shares of Common Stock authorized for issuance pursuant to all types of awards under the 2020 Stock Plan would be increased from 2,900,000 to 4,100,000, while the maximum number of shares of Common Stock that may be granted as incentive stock options (“ISOs”) would remain at 1,500,000. The foregoing share increase is the only substantive change proposed to be made in the Second Amended and Restated 2020 Stock Plan.

We believe that the use of stock-based compensation is essential to attract and retain the services of individuals who are likely to make significant contributions to our success and to promote exceptional service and future contributions to the Company. Stock-based awards also encourage ownership of Common Stock by our directors, executive officers, and other employees. Outstanding stock-based awards have included stock options, restricted stock units (“RSUs”) and performance share awards (“PSUs”). As of April 6, 2026, only 456,443 shares were available for future grants of awards under the 2020 Stock Plan. The proposed increase in shares authorized to be issued by 1,200,000 will give us the flexibility to continue to provide stock-based incentive compensation to our senior management, key employees, and non-employee directors at a competitive level. Additional information regarding the Company’s use of stock-based awards appears below under “Additional Equity Compensation Plan Information".

Important Features of the 2020 Stock Plan

As described in more detail below, the 2020 Stock Plan includes several features intended to enhance long-term stockholder interests, none of which features would be changed in the Second Amended and Restated 2020 Stock Plan:

•
No Liberal Share Counting. The 2020 Stock Plan prohibits the Company from re-using shares that were used to pay the exercise price of, or tax withholding obligations relating to, awards. The only shares that may be returned to the pool available for future awards under the 2020 Stock Plan relate to awards that have been canceled, forfeited, expired, or settled in cash.
•
Minimum Vesting Requirements. Stock-based awards generally may not provide for vesting earlier than one year after grant, with a carve-out for five percent of the shares in the pool. As proposed to be amended, the carve-out will cover up to 205,000 shares of Common Stock.
•
Dividends. Cash dividends or dividend equivalents may not be paid or accrued with respect to unvested awards.
•
Maximum ten-year term of stock options and stock appreciation rights. The maximum term of each award of stock options or stock appreciation rights (“SARs”) is ten years.
•
No repricing or grant of discounted stock options or SARs. The 2020 Stock Plan does not permit the repricing of options or SARs. All stock options and SARs must have an exercise or base price equal to or greater than the fair market value of the Common Stock on the date of grant.

- 14 -

•
Nontransferability of Awards. Awards granted under the 2020 Stock Plan are not transferable other than by will or the laws of descent and distribution.
•
Clawback. Awards granted under the 2020 Stock Plan are subject to the Company’s compensation recovery policies.

Vote Required and Board Recommendation

The affirmative vote of a majority of the votes cast on Proposal 2 is required for approval. Abstentions and broker non-votes will have no effect on the outcome of the vote.

The Board of Directors unanimously recommends that you vote FOR approval of the Second Amended and Restated 2020 Stock Plan.

SUMMARY OF THE SECOND AMENDED AND RESTATED 2020 STOCK PLAN

Administration. Except to the extent the Board determines otherwise, the Second Amended and Restated 2020 Stock Plan will be administered by the Compensation Committee (referred to in this section as the "Committee"). Under its charter, the Committee must consist of two or more directors of the Company, each of whom satisfies the applicable independence criteria of the stock exchange or quotation system on which the Company's common stock is listed or quoted and qualifies as a "non-employee director" as defined by Rule 16b-3 promulgated under the Exchange Act.

Eligibility. Directors, officers and other key employees, and outside consultants are eligible to receive awards under the 2020 Stock Plan. Individuals who receive awards are referred to as "Participants." As of April 6, 2026, eight non-employee directors, four executive officers, and approximately 90 other employees were considered eligible to be selected by the Committee to receive awards under the 2020 Stock Plan. Compensation paid to the Company's non-employee directors in any calendar year may not exceed a total of $400,000 per director, including all cash compensation and the value of all stock-based awards granted during the year.

Shares Available for Issuance under the Second Amended and Restated 2020 Stock Plan. A maximum of 4,100,000 shares of Common Stock may be made the subject of awards granted under the Second Amended and Restated 2020 Stock Plan, an increase of 1,200,000 shares from the current limit of 2,900,000. The maximum amount will be adjusted in the event of certain changes in the Company's capitalization.

If an award is canceled or expires for any reason before having been fully vested or exercised, or is exchanged for another award, or is otherwise forfeited, all shares covered by such award will be added back to the number of shares available for future awards. The shares subject to awards that are payable or settled solely for cash also will not reduce the number of shares available for future awards. In no event will any of the following shares again become available for other awards: (i) shares tendered or withheld in respect of taxes; (ii) shares tendered or withheld to pay the exercise price of options; (iii) shares repurchased by the Company from a Participant with the proceeds from the exercise of options; and (iv) the total number of shares underlying exercised stock appreciation rights, not just the net number of shares issued.

The 1,200,000 additional shares of Common Stock that will be authorized for issuance under the Second Amended and Restated 2020 Stock Plan represent approximately 4.9 percent of outstanding shares as of April 6, 2026. The closing price of the Common Stock on The Nasdaq Stock Market on April 6, 2026, was $29.82. No awards have been made under the 2020 Stock Plan since its amendment in 2023 that are subject to stockholder approval. If the Second Amended and Restated 2020 Stock Plan is approved, the Committee will determine the number and types of awards that will be granted under the increase in shares authorized for issuance in its sole discretion.

Duration of the 2020 Stock Plan. The 2020 Stock Plan will terminate on May 27, 2030, or, if earlier, when awards have been granted covering all available shares or the plan is otherwise terminated by the Board. Termination of the 2020 Stock Plan will not affect outstanding awards.

Description of Awards under the 2020 Stock Plan. The Committee may make awards to eligible Participants of ISOs, non-qualified stock options ("Nonqualified Options"), stock appreciation rights ("SARs"), restricted shares of Common Stock ("Restricted Shares"), RSUs, and PSUs. To date, no ISOs, SARs or Restricted Shares have been granted under the 2020 Stock Plan. The general terms of the available types of awards are summarized below. Each award is evidenced by a written agreement between the Company and the Participant with such terms and conditions as are approved by the Committee in its discretion, subject to the provisions of the 2020 Stock Plan.

Stock Options. Options provide Participants with the right to purchase shares at a predetermined exercise price. The Committee may grant ISOs or Nonqualified Options. Each award agreement states the option exercise price per share

- 15 -

of Common Stock purchasable under each option, which may not be less than 100 percent of the fair market value of a share on the date of grant. The applicable award agreement specifies when the option becomes exercisable, which may be in full or in installments based on continuation of employment over a specified period, satisfaction of performance goals, or other criteria. No option may be exercised after the expiration of its term, which may be no longer than ten years from the date of grant. The Committee determines the terms of each ISO or Nonqualified Option at the time of grant.

Special rules apply for ISOs. The terms of ISOs and the applicable award agreement must conform to the statutory and regulatory requirements of Section 422 of the Internal Revenue Code of 1986 (the "Code"). ISOs may only be granted to employees of the Company or its subsidiaries. The maximum number of shares as to which ISOs may be granted under the Second Amended and Restated 2020 Stock Plan is 1,500,000.

SARs. A SAR is an award entitling a Participant to receive an amount equal to the excess (or, if the Committee determines at the time of grant, a portion of the excess) of the fair market value of a share of Common Stock on the date of exercise of the SAR over the base price multiplied by the number of shares as to which the SAR is being exercised. The base price may not be less than 100 percent of the fair market value of a share on the date of grant. Upon the exercise of a SAR, payment may be made in cash, shares of Common Stock, or in any combination of the foregoing as the Committee may determine. No SAR may be exercised after the expiration of its term, which may be no more than ten years from the date of grant.

Restricted Shares. A Restricted Share is an award of shares to a Participant that is subject to such terms and conditions as the Committee deems appropriate, including, for example, completing a specified number of years of service or attaining specified performance goals. No cash or other consideration is required to be paid for shares subject to an award of Restricted Shares. Any portion of an award of Restricted Shares that is not vested because the specified conditions were not met is forfeited.

Restricted Stock Units. RSUs are units (with each unit having a value equivalent to one share of Common Stock) granted to a Participant on such terms as the Committee may determine, including, for example, a requirement that the Participant forfeit such RSUs upon termination of employment or service as a non-employee director. Upon vesting of an award of RSUs, the Participant is entitled to receive a payment in an amount equal to the aggregate fair market value of the shares covered by such RSUs at the end of the applicable restriction period. Payment shall be made in restricted or unrestricted shares of Common Stock equal to the number of RSUs, in installments, in cash, or in any other manner or combination as determined by the Committee.

Performance Share Awards. A PSU represents a right of a Participant to a share unit having a value equal to one share of Common Stock. The Committee determines whether and to whom PSUs are granted, the performance goals applicable to each award, the periods during which performance is to be measured, and all other limitations and conditions applicable to the PSUs. Payment of PSUs shall be made in cash or shares of Common Stock, as designated by the Committee. Payment shall be made in a lump sum or in installments and shall be subject to such other terms and conditions as shall be determined by the Committee. Following the end of the performance period, a participant holding PSUs will be entitled to receive payment of an amount, not exceeding the maximum value of the PSUs, based on the achievement of the performance goals for such performance period, as determined by the Committee.

Provisions Governing All Awards. All awards under the Second Amended and Restated 2020 Stock Plan will be subject to the following provisions:

Minimum Vesting Period. No award may vest in whole or in part before the one-year anniversary of the grant of such award; provided that the Committee may grant awards covering up to five percent of the pool of shares authorized for issuance without regard to the foregoing restriction. Under the Second Amended and Restated 2020 Stock Plan, this carve-out will cover up to 205,000 shares of Common Stock. Awards covering a total of 5,521 shares of Common Stock have been granted with less than a one-year vesting period through April 6, 2026. The awards were made to new Board members who were appointed with less than one year remaining until the applicable vesting date. The provision does not restrict the Committee's authority, in its sole discretion, to accelerate the vesting of, or waive any restrictions applicable to, any outstanding awards.

Performance Goals. If an award is intended to be performance-based, the Committee establishes performance goals for specific performance periods on the basis of such criteria as the Committee may select, such as performance criteria for the Company, an operating group or a branch, a Participant's individual performance, or a combination of both. Performance goals may be objective or subjective.

Rights as Stockholders. Participants have no rights of a stockholder with respect to shares subject to an award until such shares are issued in the name of the Participant, including the right to receive cash dividends or dividend

- 16 -

equivalents. No cash dividends or dividend equivalents will be paid or accrued on Restricted Shares before they vest. Stock dividends issued with respect to unvested Restricted Shares will be subject to the same restrictions. Unless the award agreement for Restricted Shares provides otherwise, a Participant will have voting rights with respect to unvested Restricted Shares that have not been forfeited.

Change in Control. If a change in control of the Company occurs, the Committee has broad discretion to, among other things, accelerate the vesting of outstanding awards, convert or replace outstanding awards, or cancel outstanding awards in exchange for specified payments. Replacement and converted awards would continue to vest over the period (and at the same rate) as the awards which the replacement or converted awards replaced, unless otherwise determined by the Committee. The Committee may provide for a 30-day period prior to a change in control during which all outstanding awards will tentatively become fully vested; when the change in control occurs, all outstanding and unexercised awards will then immediately terminate. Unless the Committee specifically provides otherwise in an award agreement, awards will become vested as of a change in control date only if, or to the extent, such acceleration of vesting does not result in an "excess parachute payment" within the meaning of Section 280G(b) of the Code. The definition of change in control used in the 2020 Stock Plan is summarized below under "Information Regarding Agreements with Executive Officers."

No Repricing. No options or SARs may be repriced, replaced, regranted through cancellation, or modified without stockholder approval (except in connection with a change in the Company's capitalization or similar event), if the effect would be to reduce the exercise or base price for the shares underlying the award.

Nontransferability of Awards. Awards are not transferable other than by will or the laws of descent and distribution and may be exercised during the Participant's lifetime only by the Participant.

Clawback of Compensation. All compensation pursuant to awards are subject to recovery under the Company's compensation recovery policy described under "Compensation Recovery “Clawback” Policy" below, as well as any future policies that may be adopted by the Company.

Termination of Employment. The terms and conditions under which an award may be exercised, if at all, after a Participant's termination of employment or service as a non-employee director is determined by the Committee and specified in the applicable award agreement.

Amendment and Termination. The Board may amend the 2020 Stock Plan at any time, but no such amendment is effective unless approved by the Company's stockholders to the extent that such approval is required to satisfy applicable law or securities exchange listing requirements, as is the case with regard to the amendment to increase the number of shares of Common Stock covered by the plan as reflected in the Second Amended and Restated 2020 Stock Plan. The Board may also terminate the 2020 Stock Plan at any time, but termination will not affect outstanding awards. In addition, an amendment will not materially impair the rights of a Participant with respect to outstanding awards without the Participant's consent, unless the amendment provides for payment of the value of the vested portion of the award to the Participant.

Prior Stock Option Grants Under the 2020 Stock Plan. Anthony Harris, our Chief Financial Officer, was granted Nonqualified Options to purchase 12,500 shares of Common Stock at an exercise price of $42.79 per share on November 12, 2024, and additional Nonqualified Options to purchase 22,000 shares of Common Stock at an exercise price of $44.34 per share on December 4, 2024. The expiration dates, market values as of December 31, 2025, and other material terms of the options held by executive officers are shown in the table under “Outstanding Equity Awards at December 31, 2025” below. Except as shown in that table, no other current executive officer, current non-employee director, associate of any current executive officer or non-employee director, or any non-executive employee has been granted ISOs or Nonqualified Options under the 2020 Stock Plan. See the table under the subheading “Additional Equity Compensation Plan Information” below for additional information regarding equity awards under the 2020 Stock Plan.

EXPECTED FEDERAL INCOME TAX CONSEQUENCES

The following is a general discussion of certain U.S. federal income tax consequences relating to awards granted under the 2020 Stock Plan. This discussion is not intended to constitute tax advice, does not address all aspects of U.S. federal income taxation, does not discuss state, local, employment, and foreign tax issues, and does not discuss considerations applicable to a holder who is, with respect to the United States, a non-resident alien. This summary of federal income tax consequences does not purport to be complete and is based upon interpretations of the existing laws, regulations, and rulings, which could be altered materially with enactment of any new tax legislation. Participants should consult their own tax advisors because the summary below may not apply to a Participant's particular situation.

Under the Code, the Company will generally be entitled to a deduction for federal income tax purposes at the same time and in the same amount as the ordinary income that Participants recognize pursuant to awards. For Participants, the expected U.S. federal income tax consequences of awards are as follows:

Nonqualified Options. A Participant will not recognize income at the time a Nonqualified Option is granted. At the time a Nonqualified Option is exercised, the Participant will recognize ordinary income in an amount equal to the excess of (i) the fair market value of the shares issued to the Participant on the exercise date over (ii) the exercise price paid for the shares. At the time of sale of shares acquired pursuant to the exercise of a Nonqualified Option, the appreciation (or depreciation) in value of the shares after the date of exercise will be treated either as short-term or long-term capital gain (or loss) depending on how long the shares have been held.

ISOs. A Participant will not recognize income upon the grant of an ISO. There are generally no tax consequences to the Participant upon exercise of an ISO (except that the amount by which the fair market value of the shares at the time of exercise exceeds the option exercise price will be included in the Participant's alternative minimum taxable income). If the shares are not disposed of within the later of two years from the date the ISO was granted or one year after the ISO was exercised, any gain realized upon the subsequent disposition of the shares will be characterized as long-term capital gain and any loss will be characterized as long-term capital loss. If either of these holding period requirements are not met, then a "disqualifying disposition" occurs. Upon a disqualifying disposition, (i) the Participant recognizes ordinary income in the amount by which the fair market value of the shares at the time of exercise (or, if less, the amount realized on the disqualifying disposition) exceeded the exercise price for the ISO and (ii) any excess amount realized on the disqualifying disposition over the fair market value of the shares at the time of exercise will be characterized as capital gain. If the amount the Participant realizes from a disqualifying disposition is less than the exercise price paid and the loss sustained upon the disposition would otherwise be recognized, the Participant will not recognize any ordinary income from the disqualifying disposition and instead the Participant will recognize a capital loss.

Stock Appreciation Rights. A Participant will not recognize income at the time of grant of a SAR. Upon exercise of a SAR, the Participant will recognize ordinary income in an amount equal to the value of any cash or shares that the Participant receives. At the time of sale of any shares acquired pursuant to the settlement of a SAR, the appreciation (or depreciation) in value of the shares after the date of settlement will be treated either as short-term or long-term capital gain (or loss) depending on how long the shares have been held.

Restricted Shares. In general, a Participant will not recognize income at the time of grant of Restricted Shares unless the Participant elects with respect to the Restricted Shares to accelerate income taxation to the date of the award, as described further below. In the absence of an election to accelerate income taxation to the date of an award, upon lapse of the forfeiture conditions or transfer restrictions (the "vesting date"), a Participant will recognize ordinary income equal to the fair market value of the Restricted Shares on the vesting date (less any amount the Participant paid for such Restricted Shares). If permitted by the applicable award agreement, a Participant may, within 30 days after the date of the grant, elect to immediately recognize (as ordinary income) the fair market value of the Restricted Shares (less any amount the Participant paid for the Restricted Shares), determined as of the date of grant (without regard to the forfeiture conditions and transfer restrictions). This election is made pursuant to Section 83(b) of the Code. If a Participant making such an election later forfeits the Restricted Shares, no deduction or capital loss will be available to the Participant (even though the Participant previously recognized ordinary income with respect to such Restricted Shares).

Restricted Stock Units and Performance Share Awards. In general, a Participant will not recognize income at the time of grant of RSUs or PSUs. Upon distribution of cash or unrestricted shares that the Participant receives in settlement of RSUs or PSUs after vesting, a Participant will recognize ordinary income equal to the value of any cash or unrestricted shares that the Participant receives. At the time of sale of any shares acquired pursuant to the settlement of RSUs or PSUs, the appreciation (or depreciation) in value of the shares after the date of settlement will be treated either as short-term or long-term capital gain (or loss) depending on how long the shares have been held.

Payment of Exercise Price or Tax Withholding in Shares. The Committee may permit or require Participants to pay all or a portion of the exercise price of stock options or tax withholding obligations upon exercise or vesting of an award by

- 18 -

tendering previously acquired shares of common stock or by relinquishing a portion of the shares otherwise issuable upon exercise or vesting. If an option is exercised and payment is made in shares the Participant already owns, there generally is no taxable gain or loss to the Participant other than any gain recognized as a result of exercise of the option, as described above. A number of new shares equal to the number of shares transferred to pay the exercise price will have a basis equal to the basis of the transferred shares and the same holding period as the transferred shares. (If ISO shares are used to exercise a Nonqualified Option, a number of the new shares equal to the number of ISO shares transferred to pay the exercise price of the Nonqualified Option will also be treated as ISO shares subject to the same holding periods as the original ISO shares.) The remainder of the new shares will have a new holding period and a basis equal to (i) for Nonqualified Options, the fair market value of those shares on the exercise date or (ii) for ISOs, zero.

Special Tax Provisions. A Participant will also be subject to a 3.8 percent tax on the lesser of (i) the Participant's "net investment income" for the relevant tax year and (ii) the excess of the Participant's modified adjusted gross income for the taxable year over a certain threshold. Net investment income generally includes net gains from the disposition of shares. Under certain circumstances, the accelerated vesting, cash-out or accelerated lapse of restrictions on awards in connection with a change in control of the Company may be deemed an "excess parachute payment" for purposes of the golden parachute tax provisions of Section 280G of the Code, the Participant may be subject to a 20 percent excise tax, and the Company may be denied a tax deduction.

## PROPOSAL 3: ADVISORY VOTE TO APPROVE COMPENSATION OF OUR EXECUTIVE OFFICERS

Public companies are required to give their stockholders the opportunity, on an advisory basis, to approve or disapprove the compensation of their named executive officers and, at least every six years, to vote, on an advisory basis, on how frequently they would like the company to hold an advisory vote on the compensation of executive officers. At the 2023 annual meeting, the Company's stockholders approved the Board's recommendation that an advisory vote on executive compensation be conducted annually. Accordingly, we are conducting an advisory vote to approve the compensation of the Company's executive officers again this year. Unless the Board changes its policy, the next "say on pay" advisory vote will be held in 2027.

The Compensation Committee believes that executive compensation should align with the stockholders' interests, without encouraging excessive or unnecessary risk. This compensation philosophy and the program structure approved by the Compensation Committee are central to the Company's ability to attract, retain, and motivate individuals who can achieve our goals and provide stability in leadership. Our philosophies and goals with respect to compensation are explained in detail below under the subheading "Executive Compensation – Compensation Discussion and Analysis – Compensation Philosophy and Objectives." A detailed description of compensation earned or paid to our named executive officers in 2025 follows that discussion and analysis.

This advisory vote, which is not binding on the Company, the Compensation Committee, or the Board, is intended to address the overall compensation of our executive officers and the policies and practices described in this proxy statement. The Board and the Compensation Committee value the opinions of our stockholders and will take the outcome of the vote into account when considering future executive compensation arrangements.

The Board of Directors unanimously recommends that you vote, on an advisory basis, FOR the following resolution:

"RESOLVED, that the compensation paid to our named executive officers, as disclosed in this proxy statement pursuant to Item 402 of Regulation S-K adopted by the SEC, including the Compensation Discussion and Analysis, executive compensation tables and accompanying footnotes and narrative discussion, is hereby approved."

The above-referenced disclosures appear below under the heading "Executive Compensation" in this proxy statement.

The above resolution will be deemed to be approved if it receives the affirmative vote of a majority of the votes cast at the Annual Meeting. Abstentions and broker non-votes will have no effect on the outcome of the vote.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Compensation Philosophy and Objectives. The Compensation Committee (for purposes of this section, the "Committee") has responsibility for establishing, implementing, and continually monitoring adherence with the Company’s compensation philosophy. The goal of the Committee is to ensure that the total compensation paid to the Company’s executive officers is fair, reasonable, and competitive.

The Committee believes that the most effective executive compensation program is one that is designed to reward the achievement of specific annual and long-term strategic goals by the Company. The principles underlying our compensation policies are:

•
To attract, motivate, and retain high-quality executive officers;
•
To provide competitive compensation relative to compensation paid to similarly situated executives; and
•
To align the interests of executives with our overall risk profile to build long-term stockholder value.

At the 2025 annual meeting of stockholders, more than 96% of the votes cast with respect to the advisory vote on executive compensation approved the compensation of the Company's named executive officers. The Committee took this information into consideration in reviewing the Company's executive compensation program. Our executive compensation program processes are consistent with those established by the Committee and are monitored by the Company’s finance functions.

Peer Group and Survey Data for Comparison Purposes. For several years, the Committee has retained Mercer, a nationally recognized compensation consultant, to provide advice to the Committee regarding the structure and implementation of the Company's executive compensation program. The Committee engaged Mercer in mid-2024 to provide its recommendations for an updated peer group for purposes of comparing the Company’s executive compensation with other companies of a similar revenue size in the human resources-related and insurance-based industries. The peer group developed in consultation with Mercer did not take into consideration individual company compensation practices, and no company was included or excluded from the peer group due to paying above-average or below-average compensation. Mercer’s analysis of the Company’s compensation peer group resulted in the addition of three companies, CRA International, Inc., Kelly Services, Inc., and ProAssurance Corp., and removal of three other companies due to their larger size or poor financial performance. It was the consensus of the Compensation Committee that the following list of peer companies was appropriate for purposes of asking Mercer to prepare an updated survey of comparative executive compensation data for all executive officer positions. As discussed in more detail below, the resulting analysis was one of the factors considered by the Compensation Committee during its deliberations and decision-making with regard to the Company’s 2025 executive compensation program.

· ASGN Incorporated | · Kelly Services, Inc .
· CBIZ, Inc. | · KForce Inc.
· CRA International, Inc. | · Korn/Ferry International
· Cross Country Healthcare, Inc. | · ProAssurance Corp.
· Heidrick & Struggles International, Inc. | · Resources Connection, Inc.
· Huron Consulting Group Inc. | · TrueBlue, Inc.
· ICF International, Inc. | · United Fire Group, Inc.

2025 Executive Compensation Components. The principal components of compensation for executive officers in 2025, similar to past years, were:

•
Base salary;
•
Target annual cash incentive compensation, including both performance-based compensation and discretionary bonuses;
•
Grants of restricted stock units ("RSUs"); and
•
Grants of performance share awards ("PSUs").

After reviewing the comparative peer group analysis provided by Mercer in October 2024, the Compensation Committee concluded that the Company’s executive compensation program had incorporated a balanced approach to setting performance metrics and goals for both short-term and long-term incentive compensation, resulting in the successful creation of shareholder value. Therefore, the Compensation Committee determined that the structure and approach of the Company’s executive compensation program was achieving its intended objectives of motivating superior performance and retention, such that there was no need to modify the structure of the program. In light of the goals of the program, as well as the Company’s positive financial performance under the CEO’s leadership, the Committee established a goal of gradually moving total compensation for the CEO closer to the 75th percentile of the Company’s peer group, with total cash compensation pegged at approximately the 50th percentile compared to the peer group. The Compensation Committee also discussed the CEO’s recommendations for the salary and target amounts of compensation for the Company’s executive officers other than himself and approved his recommendations.

Base Salary

Salary levels of executive officers are reviewed periodically by the Committee and the CEO as part of the performance review process, as well as in connection with a promotion or other change in job responsibility. In determining base salaries for executives in 2025, the Committee primarily considered:

•
Information provided by Mercer regarding merit increases and increases in total salaries by similarly sized companies as described above under the subheading "Peer Group and Survey Data for Comparison Purposes";
•
The scope of responsibilities of the Company’s executive officers, including leadership, experience, skills, expertise, and knowledge; and
•
Individual performance and contributions to the Company’s financial and strategic objectives.

- 21 -

In February 2025, the Committee approved 2025 executive officer base salary levels, effective April 1, 2025, as follows: Mr. Kramer, $899,000, an increase of 5%; Mr. Harris, $510,000, an increase of 5%; Mr. Blotz, $580,000, an increase of 4%; and Mr. Potts, $390,000, an increase of 4%.

Annual Cash Incentive Compensation

The Company has an Annual Cash Incentive Award Plan (the "Annual Incentive Plan") that provides for annual awards of cash compensation to the Company’s executive officers based on the achievement of objective corporate performance goals selected by the Committee. In addition, the Committee typically awards discretionary bonuses based on each officer’s individual performance during the year. The total bonus opportunity for 2025 was divided such that 80% related to achievement of four corporate performance goals and 20% to individual performance. Following year end, the Committee determined the extent to which the corporate and individual performance goals were achieved. An executive must remain employed by the Company through the date of the Committee's determination of performance to be eligible to receive annual cash incentive payouts.

In April 2025, the Committee set the target bonus amounts at 115% of base salary for Mr. Kramer and at 80% of base salary for Messrs. Harris, Blotz and Potts. The target amounts related to achievement of corporate performance goals were as follows: Mr. Kramer, $827,080; Mr. Harris, $326,400; Mr. Blotz, $371,200; and Mr. Potts, $249,600. The target bonus amounts tied to corporate financial metrics preliminarily approved by the Committee related to gross billings growth, net income, gross margin as a percentage of gross billings, and WSE adds from new clients, with each goal weighted equally. The cash payouts were subject to adjustment on a sliding scale based on the actual achievement of a given metric above or below the target level. Payouts for a given performance target would be 25% at the minimum achievement level and capped at 200% at the maximum achievement level. There would be no payout at an achievement level below the established minimum.

The following table shows the Committee's determination of the bonus payout percentages achieved for each respective metric under the Annual Incentive Plan.

Metric |  | Target |  |  | Actual |  |  | Minimum Achievement Level |  |  | Maximum Achievement Level |  |  | Payout Percentages |
Gross billings growth |  |  | 8.50 | % |  |  | 8.59 | % |  |  | 6.00 | % |  |  | 11.90 | % |  |  | 103 | %
Net income |  | $ | 40,719,610 |  |  | $ | 54,448,248 |  |  | $ | 34,611,669 |  |  | $ | 48,863,532 |  |  |  | 200 | %
Gross margin as a percentage of gross billings |  |  | 2.74 | % |  |  | 2.89 | % |  |  | 2.67 | % |  |  | 3.01 | % |  |  | 155 | %
Worksite employee adds |  |  | 20,614 |  |  |  | 25,232 |  |  |  | 17,522 |  |  |  | 24,737 |  |  |  | 200 | %

The actual payout amounts are shown in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table below.

The target bonus amounts for individual performance approved by the Committee in April 2025 were as follows: Mr. Kramer, $206,770; Mr. Harris, $81,600; Mr. Blotz, $92,800; and Mr. Potts, $62,400. The CEO provided the Committee with his recommendations for individual goals for the executive team that were designed to support the Company's strategic objectives and were aligned with goals for other management employees. Each executive was assigned four or five goals focused on incremental margin improvement; implementation of new software programs to enhance the Company's operations and client support functions; market development and expansion, including through expansion of client adoption of newly deployed products and cultivation of referral partners; talent development and succession planning; and ongoing initiatives to protect the Company’s intellectual property and assure compliance with changing legal requirements. In February 2026, consistent with the CEO’s recommendations, the Committee approved payouts at 75% for Messrs. Kramer and Harris, 62.5% for Mr. Blotz, and 100% for Mr. Potts.

Long-Term Equity Incentive Compensation

In 2025, the Committee continued its practice of making annual grants of RSUs to the Company's executive officers under the Company’s 2020 Stock Plan. The Committee believes that RSUs provide a near-term opportunity to receive an ownership stake in the Company, thus serving as a significant incentive aligning the long-term interests of the executive team with the interests of the Company's stockholders. Each RSU represents a contingent right to receive one share of Common Stock. The RSUs granted to executive officers typically vest in four equal annual installments, subject to continued service. The Committee fixed the dollar value of the annual RSU awards to executive officers granted on July 1, 2025, based on the closing sale price of the Common Stock on the date of grant, rounded down to the nearest whole share, as follows: Mr. Kramer, $1,573,000; Mr. Harris, $408,000; Mr. Blotz, $464,000; and Mr. Potts, $312,000. The awards are shown in the "All Other Stock Awards" column of the Grants of Plan-Based Awards table below.

The vesting of PSUs granted in 2025 is conditioned on attaining specified target cumulative amounts of gross billings and net income before taxes for the three-year period ending December 31, 2027. The target dollar values of PSUs granted on March 3, 2025, were: Mr. Kramer, $1,753,050; Mr. Harris, $433,500; Mr. Blotz, $580,000; and Mr. Potts, $234,000, with 50% of the performance shares tied to achievement of each financial metric. Target award amounts are subject to upward or downward adjustment by 2.5% for each one percent by which the actual achievement of a given financial metric is above or below the target level, but not less than 80% of the target level or more than 140% of the target level. If achievement is below the 80% level, no part of the target award tied to that financial metric would be paid. At the 80% level, 50% of the target award for the related financial metric would be paid. The maximum payout is 200% of a target award. The awards in terms of numbers of shares are shown in the "Estimated future payouts under equity incentive plan awards" column of the Grants of Plan-Based Awards table below.

In February 2026, the Committee reviewed the achievement of performance goals for PSUs granted to the executive officers in early 2023. The awards had been tied to the achievement of net income before taxes and gross billings targets for the three-year period ended December 31, 2025, with each factor weighted equally. The Committee determined that the net income before taxes goal had been achieved at the 102.9% level; the adjustment multiplier yielded a payout of 107.1% of the target award tied to that goal. The Committee determined that the gross billings goal had been achieved at the 97.3% level, yielding a payout of 93.2% of the target award tied to gross billings. The overall payout totaled approximately 100.2% of the target awards. The PSUs were settled on February 23, 2025, resulting in the issuance of shares of Common Stock as follows: Mr. Kramer, 55,206; Mr. Harris, 12,075; Mr. Blotz, 14,354; and Mr. Potts, 6,350.

Deferred Compensation Plan

Under the Company’s Nonqualified Deferred Compensation Plan adopted in 2017, executive officers and other participants may defer receipt for income tax purposes of up to 90% of salary, as well as up to 100% of bonuses and other compensation. Deferred amounts are credited to each participant's account and adjusted to reflect amounts of income, gain, or loss as if the amounts credited to such accounts had been invested in investment funds designated under the plan and selected by the participant. The Committee also approved the establishment of a Rabbi trust under which compensation deferred at the election of participants is deposited in trust and held separately from the Company's other assets, subject to the claims of the Company's creditors in the event of its bankruptcy or insolvency. Although the Company does not make cash matching contributions to participants’ accounts under the plan, RSUs that cliff vest five years following the grant date, subject to continued service, are awarded each January 1 and July 1, with a matching award of RSUs equal to 35% of the amount deferred into a participant's account during the preceding six months, up to a maximum value of $75,000 per year. The RSU awards during 2025 are shown in the Grants of Plan-Based Awards table below. Additional information about the deferred compensation plan is included under "Nonqualified Deferred Compensation" below.

Retirement Benefits

Employees, including executive officers, may participate in the Company's 401(k) defined contribution plan. The Company matches each employee's contributions at a rate of 100% on the first 3% of salary deferrals and 50% on the next 2% of salary deferrals, with a maximum Company-paid match of $14,000. All executive officers participated in the 401(k) plan in 2025.

Agreements with Executive Officers

The Company entered into employment agreements with Messrs. Kramer, Harris, and Blotz in April 2020, and with Mr. Potts in August 2020. The employment agreements provide for the payment of severance benefits upon termination of the executive’s employment for specified reasons. Each agreement includes the executive’s agreement not to compete with the

- 23 -

Company for a specified period following termination. The Committee approved the agreements with the goal of providing the Company's stockholders with greater assurance of stability within senior management.

The Company has also entered into agreements with Messrs. Kramer, Blotz, Harris, and Potts that provide, in the event of the executive's death, for the Company to make a lump sum payment to the executive’s designated beneficiary. The agreements are intended to provide a benefit to each executive’s heirs in the event of his death while employed by the Company.

The Committee approved each of the foregoing agreements, which are described in more detail under "Information Regarding Agreements with Executive Officers" below.

Compensation Recovery ("Clawback") Policy. In accordance with the Nasdaq listing rules, in October 2023, the Board adopted an updated "clawback" policy providing for the recovery of incentive compensation in specified circumstances. Under the policy, if the Company is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under applicable securities laws, including any required accounting restatement to correct a material error in previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, the Company will seek to recover compensation from any current or former executive officer who received incentive compensation that was based wholly or in part upon the attainment of a financial reporting measure during the three-year period preceding the date of the restatement and that exceeds what would have been paid to the executive under the accounting restatement. A copy of the policy is available on the Company's website at www.BBSI.com in the "Investors" section under "Governance."

Tax Deductibility of Executive Compensation. Section 162(m) of the Internal Revenue Code (the "Code") limits the amount that the Company may deduct for income tax purposes for compensation paid to our executive officers to $1,000,000 per person per tax year.

(1) Represents the potential annual cash incentive payouts under the Cash Incentive Plan based on the level of achievement of corporate performance goals approved in March 2025. The target amounts were payable if the overall achievement level was 100%, and actual payouts were subject to adjustment on a sliding scale based on the achievement of a given metric above or below the target level. Actual cash incentive payments are shown in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table above.

(2) Represents the number of shares subject to PSUs under the 2020 Stock Plan, all or a portion of which will vest on the date that the Compensation Committee determines the level of attainment of specified performance goals for the three years ending December 31, 2027, as described under "Compensation Discussion and Analysis" above. Upon vesting, the awards will be settled in shares of Common Stock. The PSUs are tied to target levels of gross billings and net income before taxes, weighted equally. Target award amounts are subject to upward or downward adjustment by 2.5% for each 1% by which the actual achievement of a given financial metric is above or below the target level, but not less than 80% or more than 140% of the target level. If achievement is below the 80% level, no part of the target award tied to that financial metric is paid. The maximum payout for a given metric is 200% of the target award for that metric.

(3) Reflects the grant of RSUs as a matching contribution in connection with the Company’s nonqualified deferred compensation plan. The RSUs will vest on the five-year anniversary of the grant date, subject to continued service, and will be settled by delivery of unrestricted shares of Common Stock on the vesting date. Vesting of the RSUs would accelerate upon a change in control of the Company or a participant's death or termination of employment due to disability.

- 26 -

(4) Reflects the grant of RSUs under the 2020 Stock Plan. Each RSU represents a contingent right to receive one share of Common Stock. The RSUs typically vest in four equal annual installments beginning on the one-year anniversary of the grant date, subject to continued service, and will be settled by delivery of unrestricted shares of Common Stock on the vesting date. Vesting of the RSUs would accelerate upon a change in control of the Company or a participant's death or termination of employment due to disability.

(5) Represents the grant date fair value of PSUs based on the assessment of the probable outcome of the specified performance conditions (50%) and the closing sale price of the Common Stock on the grant date multiplied by the target number of shares underlying the awards.

(6) The amounts shown represent the grant date fair value of RSUs based on the closing sale price of the Common Stock on the grant date multiplied by the number of shares underlying the awards.

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, we are providing the following information about the relationship between the annual total compensation of our employees and the annual total compensation of our CEO for 2025, our last completed fiscal year:

•
The annual total compensation of our CEO was $5,002,291.
•
The median of the annual total compensation of all of our employees other than our CEO (based on our median employee identified under the methodology described below) was $116,593.
•
The resulting ratio of our CEO's annual total compensation to the annual total compensation of our median employee is 43 to 1.

The pay ratio stated above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records. The SEC's rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratios reported by other companies may not be comparable to our pay ratio stated above.

We completed the following steps to identify the median of the annual total compensation of our employees and to determine the annual total compensation of our median employee and CEO:

•
On December 31, 2025, the date we used to determine the employees to be included in our ratio calculation, our employee population consisted of approximately 896 individuals, including full-time, part-time and temporary employees (excluding temporary staffing employees) employed on that date.
•
The employee number excludes the employees of our professional employer services clients, as those clients determine the compensation of their employees. Similarly, the number excludes our temporary staffing employees who work at our customers' job sites, because the compensation paid to such employees is established by our customer's order.
•
To find the median of the annual total compensation of the individuals (other than our CEO) in our employee population as described above, we used wages from our payroll records as reported to the Internal Revenue Service on Form W-2 for the calendar year 2025. In making this determination, we annualized the compensation of full-time and part-time permanent employees who were employed on December 31, 2025, but who did not work for us the entire year. No full-time equivalent adjustments were made.
•
We identified our median employee using this compensation measure and methodology, which was consistently applied to all employees included in the calculation.
•
After identifying the median employee, we added together all of the elements of that employee’s compensation for calendar year 2025 in accordance with the requirements applicable to calculating annual total compensation for purposes of the Summary Compensation Table above.

For the annual total compensation of our CEO, we used the amount reported for our CEO in the "Total" column for 2025 in the Summary Compensation Table above.

(1) Amounts are also included, as applicable, in the Salary, Bonus and Non-Equity Incentive Plan Compensation columns of the Summary Compensation Table above.

(2) None of the amounts in this column are included in the Summary Compensation Table because the earnings under the NDCP were not preferential or above-market.

(3) Includes amounts previously reported in Summary Compensation Tables for prior years as follows: Mr. Kramer, $1,361,956; Mr. Harris, $1,118,347; Mr. Blotz, $185,981; and Mr. Potts, $428,880.

Upper management, including executive officers, are eligible to participate in the Barrett Business Services, Inc. Nonqualified Deferred Compensation Plan (the "NDCP"). Key features of the NDCP are as follows:

•
Deferrals. Participants may make an advance election to defer up to 90% of their annual base salary, 100% of annual cash performance and discretionary bonuses, and 100% of other compensation as permitted in the Company’s discretion.
•
Vesting. Participants are immediately vested in credits for their contributions and related earnings.
•
Form of Payment. Participants may make elections regarding distribution of their vested account balance in accordance with the terms and conditions set forth in the NDCP. The payment may be in a lump sum on a specified date at least five years following the end of the period in which the deferred amount was earned (an "in-service distribution") or on the first business day of the seventh month following separation from service. Alternatively, for in-service distributions or distributions following retirement at or after age 60 with at least 10 years of service, the distribution may be paid in up to 10 equal annual installments. A lump-sum distribution will be made 60 days following death or disability. Distributions are also permitted in the event of an unforeseeable emergency. Subsequent deferral elections with respect to deferred amounts are also permitted.
•
Earnings on Account Balances. Participants may allocate the amounts deferred into their accounts under the NDCP among 37 investment fund alternatives offered by the Company. Investment instructions may be submitted on any business day. Hypothetical gains and losses are credited to participant accounts based on their investment elections. The following table shows investment fund alternatives selected by participants during 2025 and annualized returns for each investment alternative for 2025:

The Company does not make cash matching contributions to participants’ accounts in the NDCP. However, as an incentive to participate in the NDCP and as a retention tool, the Committee approved the automatic award of RSUs under the 2020 Stock Plan each January 1 and July 1 to participants in the NDCP based on the fair market value of a share on the grant date, with a total dollar value equal to 35% of the amount deferred into the participant's account under the NDCP during the preceding six months. The grant date fair value of RSUs awarded to a single participant in connection with the NDCP is limited to $75,000 per year. The restriction period for RSUs awarded in connection with the NDCP will expire, and the RSUs will vest in full, on the fifth anniversary of the grant date, so long as the participant continues to be an employee of the Company on the vesting date. Vesting of the RSUs will be accelerated if the participant ceases to be an employee due to death or disability or in the event of a change in control of the Company. RSUs that do not vest on or before the expiration of the restriction period are forfeited. A total of 5,071 RSUs were granted to executive officers in connection with the NDCP during 2025. The grants are shown under "Outstanding Equity Awards at December 31, 2025" above.

(3) Peer Group Total Shareholder Return is calculated based on the S&P 1500 Human Resource & Employment Services Index, a published industry index that is considered reflective of the Company's peers, for each respective year shown in the table, assuming an initial investment of $100 on December 31, 2020.

(4) Reflects after-tax net income prepared in accordance with GAAP for each of the years shown.

(5) Gross billings is the financial measure that, in the Company’s assessment, represents the most important performance measure used to link Company performance to compensation actually paid to our PEOs and other NEOs, as it is the primary metric used in understanding the volume of the Company's business and serves as an important performance metric in managing the Company's operations, including the preparation of internal operating forecasts and establishing executive compensation performance goals. We calculate gross billings by including direct payroll costs that would otherwise be excluded from professional employer organization revenue because we are not the primary obligor for wage payments to our clients' employees.

Relationship between Compensation Actually Paid and Financial Performance Measures

Compensation Actually Paid ("CAP") to Mr. Kramer was higher in 2021-2024 compared to 2025. The decrease in Mr. Kramer’s compensation is primarily the result of the decrease in the Company’s stock price in 2025. The average NEO CAP was also higher in 2021-2024 compared to 2025, primarily due to the decrease in the Company’s stock price in 2025.

Total Shareholder Return increased from 2021 to 2024 primarily due to the increase in the Company’s stock price during this period. Total Shareholder Return decreased in 2025 primarily due to the decrease in the Company's stock price during this

- 33 -

period. Net Income, Gross Billings, and total Worksite Employees also increased between 2021 and 2025. Each of these metrics is directionally aligned with the increases in CAP for both Mr. Kramer and the other NEOs, except in 2025 where the CAP for Mr. Kramer and the other NEOs decreased compared to the prior year. Total Shareholder Return increased from 2021 to 2025, compared to a decrease in Peer Group Total shareholder Return for the same period.

The following list presents the financial performance measures that the Company considers to have been the most important in linking CAP to our PEO and Non-PEO NEOs for 2025 to Company performance. The measures in the list are not ranked.

Information Regarding Agreements with Executive Officers

Employment Agreements. On April 22, 2020, the Company entered into Employment Agreements with Messrs. Kramer, Harris, and Blotz, effective as of March 5, 2020. On August 14, 2020, the Company entered into an Employment Agreement with Mr. Potts, effective as of September 16, 2020. Each of the Employment Agreements has a term ending on July 1, 2026, with a one-year extension on July 1 of each year, unless either the Company or the executive gives notice to the other party of nonrenewal at least 90 days in advance.

During the term of each of the Employment Agreements, the executives will be entitled to salary, annual cash incentive compensation, health and other employee benefits, and stock-based awards as approved by the Committee under the Company’s executive compensation program. The general parameters of the current executive compensation program are described under "Compensation Discussion and Analysis" above.

If an executive’s employment is terminated by the Company other than for cause, disability or death, or by the executive for good reason, the Employment Agreements provide for payment of cash severance, as well as acceleration of equity compensation in certain circumstances. Payment of severance benefits is conditional on the delivery by the executive of a release of claims against the Company. The Employment Agreements also include noncompetition and nonsolicitation provisions that apply throughout an executive’s employment with the Company, as well as after termination of his employment, regardless of the reason, for a period of 18 months for Mr. Kramer and 12 months for Messrs. Harris, Blotz and Potts.

Summaries of the definitions of certain terms used in the Employment Agreements are as follows:

"Cause" means embezzlement, willful misconduct, gross negligence, dishonesty, or other fraudulent acts involving the Company, its business operations or the performance of the executive’s duties, including refusal to comply with legal directives of the Board; a material breach of the executive’s fiduciary duties to the Company (unless remedied as provided in the agreement); a willful material breach of the confidentiality provisions of the agreement or a confidentiality policy of the Company; or an act or omission that materially injures the Company's reputation, business affairs, or financial condition if the injury reasonably could have been avoided by the executive, including conviction of a felony or crime involving dishonesty or moral turpitude.

"Good reason" generally means, in the absence of the executive’s written consent, a material reduction in the executive's authority, duties, or responsibilities or those of the person to whom the executive is required to report; a material decrease in the executive’s base compensation (with certain exceptions); a relocation or transfer of the executive’s principal place of employment by a distance of more than 50 miles; or a material breach of the Employment Agreement by the Company.

"Change in control" means a change in the ownership or effective control of the Company or a change in the ownership of a substantial portion of the assets of the Company, as defined in regulations promulgated under Section 409A of the Code, or in subsequent regulations or other guidance published by the Internal Revenue Service.

Potential Benefits in the Absence of a Change in Control. If the employment of our executive officers had been terminated on December 31, 2025, without cause or for good reason in the absence of a change in control, the executives would have been entitled to the payment of cash severance, as well as acceleration of the vesting of a specified number of RSUs, as shown in the table below. A description of benefits payable under the NDCP is included under "Nonqualified Deferred Compensation" above.

- 34 -

|  | Lump |  |  |  |  |  |  |
|  | Sum Cash |  |  | Value of |  |  |  |
|  | Severance |  |  | Accelerated |  |  |  |
Name |  | Payment(1) |  |  | RSUs(2) |  |  | Total |
Gary E. Kramer |  | $ | 2,899,275 |  |  | $ | 2,844,531 |  |  | $ | 5,743,806 |
Anthony J. Harris |  | $ | 918,000 |  |  | $ | 517,803 |  |  | $ | 1,435,803 |
Gerald R. Blotz |  | $ | 1,044,000 |  |  | $ | 661,086 |  |  | $ | 1,705,086 |
James R. Potts |  | $ | 702,000 |  |  | $ | 416,705 |  |  | $ | 1,118,705 |

(1) Equals the executive's annual base salary level at December 31, 2025, plus the target cash incentive bonus for 2025, for Messrs. Harris, Blotz and Potts, and 1.5 times that amount for Mr. Kramer, payable in a lump sum.

(2) Reflects the market value, based on the closing sale price of the Common Stock on Nasdaq on December 31, 2025, $36.21 per share, of the number of unvested RSUs held by the executive that were scheduled to vest on or before the one-year anniversary of December 31, 2025, for Messrs. Harris, Blotz and Potts, and 1.5 times that number of RSUs for Mr. Kramer. The Employment Agreements provide that the specified number of RSUs will be accelerated and deemed fully vested as of the date of the executive’s termination of employment without cause or for good reason in the absence of a change in control. See "Outstanding Equity Awards at December 31, 2025" above for additional information.

Potential Benefits upon a Change in Control. If an executive officer’s employment is terminated during a period beginning 3 months before and ending 24 months after a change in control, the executive would be entitled to a lump sum cash payment equal to 3 times the sum of annual base salary plus target cash incentive bonus, generally within 30 days after the later of the change in control or the termination. Under the award agreements in place under the 2015 and 2020 Stock Plans, all outstanding stock options and RSUs held by the executives will also become exercisable or vested in full following a change in control of the Company, whether or not the executive’s employment is terminated. If payment of these benefits would result in an "excess parachute payment" as defined in Code Section 280G, such payments will be reduced to the largest amount that will result in no portion of the payments being subject to the excise tax imposed by Code Section 4999. A description of benefits payable under the NDCP is included under "Nonqualified Deferred Compensation" above.

The following table shows potential payouts under the Employment Agreements with our executive officers as of December 31, 2025, assuming that employment was terminated on that date, either by the Company for reasons other than cause, death or disability, or by the executive for good reason, and that such termination occurred during a period beginning 3 months before and ending 24 months after a change in control. The table also shows the value of outstanding employee stock options and RSUs that were not vested on December 31, 2025, but would become exercisable in full upon a change in control of the Company, whether or not the executive’s employment was also terminated.

Name |  | Lump Sum Cash Severance Payment(1) |  |  | Value of Unvested Stock Options and RSUs(2) |  |  | Total(3) |
Gary E. Kramer |  | $ | 5,798,550 |  |  | $ | 5,908,935 |  |  | $ | 11,707,485 |
Anthony J. Harris |  | $ | 2,754,000 |  |  | $ | 1,574,121 |  |  | $ | 4,328,121 |
Gerald R. Blotz |  | $ | 3,132,000 |  |  | $ | 2,695,406 |  |  | $ | 5,827,406 |
James R. Potts |  | $ | 2,106,000 |  |  | $ | 1,098,430 |  |  | $ | 3,204,430 |

(1) Equal to three times the sum of the executive's annual base salary level at December 31, 2025, and the target cash incentive bonus for 2025.

(2) Reflects the market value of unvested RSUs plus the difference (the "spread") between the closing sale price of the Common Stock on the last trading day of 2025, $36.21 per share, and the per share exercise price for unvested options. See "Outstanding Equity Awards at December 31, 2025" above for additional information.

(3) The amounts shown are subject to reduction to the extent necessary to avoid imposition of the excise tax imposed under Code Section 4999 on excess parachute payments as defined in Code Section 280G.

Payments upon Death or Termination for Disability. The Company has entered into Death Benefit Agreements with Messrs. Kramer, Blotz, Harris, and Potts. Under each Death Benefit Agreement currently in place, the Company will make a lump sum payment to the executive officer’s designated beneficiary within 60 days after the date of death. The benefit would be forfeited upon an executive officer’s termination of employment with the Company for any reason other than death. At December 31, 2025, the death benefit would have been $2,000,000 for Mr. Kramer and $1,000,000 for each of Messrs. Harris, Blotz, and Potts.

- 35 -

A death benefit will be payable solely out of the general assets of the Company, which may include funds received from life insurance policies on the executive officers put in place by the Company. No death benefit will be payable under an agreement if the executive officer’s death occurs under circumstances causing the policy amount not to be paid in full.

In addition to the Death Benefit Agreements, all RSUs and stock options that are unvested at an executive officer's death or termination of employment due to disability will immediately vest in full. The value of unvested RSUs and stock options held by the named executive officers at December 31, 2025, is shown in the table above. A description of benefits payable under the NDCP is included under "Nonqualified Deferred Compensation" above.

RELATED PERSON TRANSACTIONS

Review of Related Person Transactions

Under the charter of the Audit Committee, the committee must determine whether to approve any transaction between the Company and a director, officer or stockholder that, if it did occur, would be required to be disclosed as a related person transaction in the Company's proxy statement. Under the Company's Code of Business Conduct, directors must disclose any personal interest in any proposed transaction with the Company to the Audit Committee. Directors may not participate in any decision by the Board where there is a conflict between their personal interests and the Company's interests. In reviewing a proposed transaction with a related person, the Audit Committee will consider whether the transaction is fair to and in the interests of the Company and its stockholders.

Indemnification of Directors and Officers

Our charter obligates us, to the maximum extent permitted by Maryland law, to indemnify any present or former director or officer or any individual who, while a director or officer of the Company and at our request, serves or has served another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner, trustee, employee or agent, from and against any claim or liability to which that individual may become subject or which that individual may incur by reason of his or her service in such capacity. Our charter also permits us to indemnify any employee or agent of the Company. Under Maryland law, we are permitted to advance the reasonable expenses of a director or officer upon receipt of (1) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (2) a written undertaking by him or her or on his or her behalf to repay the amount paid or reimbursed if it is ultimately determined that the standard of conduct was not met.

We have entered into indemnification agreements with each of our directors who is not also an employee. These agreements require us to indemnify these individuals to the fullest extent permitted under Maryland law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors or executive officers, we have been informed that in the opinion of the SEC such indemnification is against public policy and is therefore unenforceable.

MATTERS RELATING TO OUR
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Deloitte & Touche LLP ("Deloitte") was the Company's independent registered public accounting firm with respect to its audited financial statements for the years ended December 31, 2024 and 2025. The Company expects representatives of Deloitte to be present at the Annual Meeting and to be available to respond to appropriate questions. They will have the opportunity to make a statement at the Annual Meeting if they desire to do so.

|  | 2024 |  |  | 2025 |
Audit Fees(1) |  | $ | 2,008,560 |  |  | $ | 1,917,860 |
Audit-Related Fees(2) |  | $ | 2,060 |  |  | $ | - |

(1) Consists of fees for professional services for the audit of the Company’s and its subsidiaries’ annual financial statements for the years shown and for review of financial statements included in the Company’s quarterly reports on Form 10-Q. It also consists of fees for SOC-1 report services.

- 36 -

(2) Consists of fees for U.S. GAAP accounting research tools.

Pre-Approval Policy

The Company has adopted a policy requiring pre-approval by the Audit Committee of all fees and services of the Company's independent registered public accounting firm (the "independent auditors"), including all audit, audit-related, tax, and other legally permitted services. Under the policy, a detailed description of each proposed service is submitted to the Audit Committee jointly by the independent auditors and the Company's Chief Financial Officer, together with a statement from the independent auditors that such services are consistent with the SEC's rules on auditor independence. The policy permits the Audit Committee to pre-approve lists of audit, audit-related, tax, and other legally permitted services. The maximum term of any pre-approval is 12 months. Additional pre-approval is required for services not included in the pre-approved categories and for services exceeding pre-approved fee levels. The policy allows the Audit Committee to delegate its pre-approval authority to one or more of its members, provided that a full report of any pre-approval decision is given to the full Audit Committee at its next scheduled meeting. The Audit Committee pre-approved 100% of the fees described above.

Audit Committee Report

In discharging its responsibilities, the Audit Committee and its individual members met with the Company's management and its independent auditors, Deloitte & Touche LLP, to review the audit process and the Company's accounting functions and to review and discuss the Company's audited financial statements for the year ended December 31, 2025. In addition, the Audit Committee discussed various matters with Deloitte related to the Company's consolidated financial statements and matters required to be discussed under the applicable requirements of the SEC and the Public Company Accounting Oversight Board (the "PCAOB"), as well as the Company's internal control over financial reporting. The Audit Committee has also received written disclosures and the letter from Deloitte required by applicable requirements of the PCAOB regarding the firm’s communications with the Audit Committee concerning independence, and has discussed with Deloitte its independence.

Based on its review and discussions with management and the Company's independent auditors, the Audit Committee recommended to the Board of Directors that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

## PROPOSAL 4: RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected Deloitte & Touche LLP as the Company's independent registered public accounting firm to examine the financial statements of the Company for the fiscal year ending December 31, 2026. Although the selection of independent auditors is not required to be submitted to a stockholder vote by the Company's charter documents or applicable law, the Board has decided to ask the stockholders to ratify the selection. If the stockholders do not approve the selection of Deloitte, the Audit Committee will reconsider its selection.

If a quorum is present, the selection of Deloitte as the Company's independent auditors will be ratified upon receipt of the affirmative vote of a majority of the votes cast at the Annual Meeting. Shares that are not represented at the meeting, shares that abstain from voting on this proposal, and broker non-votes will have no effect on the outcome of the voting on this proposal.

The Board recommends that stockholders vote FOR ratification of the selection of Deloitte as the Company's independent registered public accounting firm for 2026.

OTHER MATTERS

Management knows of no matters to be brought before the Annual Meeting other than the election of directors, approval of the Second Amended and Restated 2020 Stock Incentive Plan to increase the maximum number of shares of the Company’s common stock for which awards may be granted under the plan, the advisory vote to approve our executive compensation, and ratification of the selection of independent auditors.

STOCKHOLDER COMMUNICATIONS WITH THE BOARD

Stockholder communications sent by regular mail to our principal executive offices at 8100 NE Parkway Drive, Suite 200, Vancouver, Washington 98662, to the attention of the Board (or to individual directors or committees), will be forwarded as the chair of the Audit Committee deems appropriate. Communications will not be forwarded if they do not appear to be within the scope of the Board's (or such other intended recipient's) responsibilities or are otherwise inappropriate or frivolous.

SUBMISSION OF DIRECTOR NOMINATIONS AND PROPOSALS FOR THE 2027 ANNUAL MEETING

Rule 14a-8 under the Exchange Act permits stockholders to submit certain types of stockholder proposals for inclusion in a proxy statement relating to an annual meeting. Failure to submit a proposal that complies with all of the requirements of Rule 14a-8 may result in its exclusion from the proxy statement. If a stockholder wishes to submit a proposal for inclusion in our proxy statement for our 2027 Annual Meeting, it must be received no later than the close of business (5:00 p.m. Pacific Time) on December 22, 2026. The proposal should be accompanied by the required proof of ownership of our stock and be addressed in care of our Secretary to our principal executive offices at 8100 NE Parkway Drive, Suite 200, Vancouver, Washington 98662.

The Company has adopted proxy access, which permits a stockholder (or group of no more than 20 stockholders) who has owned 3% or more of the Company’s outstanding stock continuously for a minimum of three years to nominate up to two individuals for election as directors and have the nominee(s) included in the Company’s proxy materials, but only if the stockholder (or group) and nominee satisfy the requirements set forth in Section 1.12 of the Company’s Bylaws. Any stockholder who intends to use these procedures to nominate a candidate for election to the Board for inclusion in our 2027 proxy statement must satisfy the requirements specified in our Bylaws, including providing the required notice of proxy access nomination to our Secretary. With regard to the 2027 Annual Meeting, the notice must be received no earlier than the close of business on December 24, 2026, and no later than the close of business on January 23, 2027. The notice must include the information specified in our Bylaws, including information concerning the nominee and information about the stockholder’s ownership of and agreements related to our stock. If the 2027 Annual Meeting is advanced or delayed more than 30 days from the anniversary of the 2026 Annual Meeting, a stockholder seeking to nominate a candidate pursuant to the proxy access provisions of the Bylaws must submit notice of any such nomination not later than (i) the 90th day prior to the date of the 2027 Annual Meeting or (ii) the 10th day after public announcement of the 2027 Annual Meeting date, whichever is later.

In addition, under our Bylaws, a stockholder who intends to nominate a candidate for election to the Board or to propose any business for presentation at our 2027 Annual Meeting (other than proposals submitted in compliance with Rule 14a-8) pursuant to Section 1.11 of our Bylaws, must give notice to our Secretary no earlier than December 24, 2026, and no later

- 38 -

than January 23, 2027. The notice must include the information specified in Section 1.11, including information concerning the nominee or proposal, as the case may be, and information about the stockholder’s ownership of and agreements related to our stock. However, if the Company holds the 2027 Annual Meeting more than 30 days before, or more than 30 days after, the anniversary of the date of the 2026 Annual Meeting, then the information must be received not later than (i) the 90th day prior to the 2027 Annual Meeting date or (ii) the 10th day after public announcement of the 2027 Annual Meeting date, whichever is later. We will not entertain any proposals or nominations at an annual meeting that do not meet the requirements set forth in the Company’s Bylaws or in Rule 14a-8.

BARRETT BUSINESS SERVICES, INC.

SECOND AMENDED AND RESTATED 2020 STOCK INCENTIVE PLAN

ARTICLE 1

ESTABLISHMENT AND PURPOSE

1.1 Establishment. Barrett Business Services, Inc. ("Corporation"), hereby establishes the Barrett Business Services, Inc., Second Amended and Restated 2020 Stock Incentive Plan (the "Plan"), effective on the Effective Date. Under the First Amended and Restated 2020 Stock Plan, the number of shares of Common Stock available for awards was increased from 1,500,000 to 2,900,000. The Second Amended and Restated 2020 Stock Incentive Plan increases the number of shares of Common Stock available for awards to 4,100,000.

1.2 Purpose. The purpose of the Plan is to promote and advance the interests of Corporation and its stockholders by enabling Corporation to attract, retain, and reward key employees, directors, and outside consultants of Corporation and its subsidiaries. It is also intended to strengthen the mutuality of interests between such employees, directors, and consultants and Corporation's stockholders. The Plan is designed to serve these purposes by offering stock options and other equity‑based incentive awards, thereby providing a proprietary interest in pursuing the long‑term growth, profitability, and financial success of Corporation.

1.3 Prior Plans. The Plan is separate from the Barrett Business Services, Inc., 2015 Stock Incentive Plan (the "2015 Plan"). The adoption of the Plan will neither affect nor be affected by the continued existence of the 2015 Plan, except that after May 27, 2020, no further Awards may be granted under the 2015 Plan. The Plan is also separate from the Barrett Business Services, Inc., 2009 Stock Incentive Plan, which was previously superseded by the 2015 Plan.

ARTICLE 4

DURATION OF THE PLAN AND SHARES SUBJECT TO THE PLAN

4.1 Duration of the Plan. The Plan is effective as of the Effective Date. Unless terminated by the Board on an earlier date, the Plan will terminate on May 27, 2030. Termination of the Plan will not affect outstanding Awards.

4.2 Shares Subject to the Plan. The shares which may be made subject to Awards under the Plan are Shares of Common Stock, which may be either authorized and unissued Shares or reacquired Shares. Subject to adjustment pursuant to Article 11, the maximum number of Shares for which Awards may be granted under the Plan is 4,100,000, of which the maximum aggregate number of Shares for which ISOs may be granted under the Plan is 1,500,000. If an Award under the Plan is canceled or expires for any reason prior to having been fully Vested or exercised by a Participant or is exchanged for other Awards, is otherwise forfeited or terminated, or is payable or settled solely in cash, all Shares covered by such Awards will be added back into the number of Shares available for future Awards under the Plan. Notwithstanding the foregoing, in no event will any of the following Shares again become available for other Awards: (a) Shares tendered or withheld in respect of taxes, (b) Shares tendered or withheld to pay the exercise price of Options, (c) Shares repurchased by the Corporation from the Participant with the proceeds from the exercise of Options, and (d) Shares underlying any exercised SARs. Shares issued in connection with awards that are assumed, converted, or substituted pursuant to a merger, acquisition, or similar transaction entered into by the Corporation shall not reduce the number of Shares available for issuance under the Plan.

4.3 Reservation of Shares. Corporation, during the term of the Plan and any outstanding Awards, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

ARTICLE 5

ELIGIBILITY

Officers and other key employees of Corporation and its Subsidiaries (including employees who may also be directors of Corporation or a Subsidiary), Consultants, Non‑Employee Board Directors, and Non-Employee Subsidiary Directors who, in the Committee's judgment, are or will be contributors to the long‑term success of Corporation, are eligible to receive Awards under the Plan.

ARTICLE 6

AWARDS

6.1 Types of Awards. The types of Awards that may be granted under the Plan are:

a.
Options governed by Article 7 of the Plan;
b.
Stock Appreciation Rights governed by Article 8 of the Plan;
c.
Restricted Awards governed by Article 9 of the Plan; and
d.
Performance Share Awards governed by Article 10 of the Plan.

In the discretion of the Committee, any Award may be granted alone, in addition to, or in tandem with other Awards under the Plan.

6.2 General. Subject to the limitations of the Plan, the Committee may cause Corporation to grant Awards to such Participants, at such times, of such types, in such amounts, for such periods, with such option exercise prices, purchase prices, or base prices, and subject to such terms, conditions, limitations, and restrictions as the Committee, in its discretion, deems appropriate. A Participant may receive more than one Award and more than one type of Award under the Plan.

6.3 Nonuniform Determinations. The Committee's determinations under the Plan or under one or more Award Agreements, including, without limitation, (a) the selection of Participants to receive Awards, (b) the type, form, amount, and timing of Awards, (c) the terms of specific Award Agreements, and (d) elections and determinations made by the Committee

A-5

with respect to exercise or payments of Awards, need not be uniform and may be made by the Committee selectively among Participants and Awards, whether or not Participants are similarly situated.

6.4 Award Agreements. Each Award will be evidenced by a written agreement (an "Award Agreement") between Corporation and the Participant. Award Agreements may, subject to the provisions of the Plan, contain any provision approved by the Committee.

6.5 Provisions Governing All Awards. All Awards are subject to the following provisions:

a.
Alternative Awards. If any Awards are designated in their Award Agreements as alternative to each other, the exercise of all or part of one Award will automatically cause an immediate equal (or pro rata) corresponding termination of the other alternative Award or Awards.
b.
Rights as Stockholders. No Participant will have any rights of a stockholder with respect to Shares subject to an Award until such Shares are issued in the name of the Participant, including the right to receive cash dividends or dividend equivalents.
c.
Employment Rights. Neither the adoption of the Plan nor the granting of any Award confers on any person the right to continued employment with Corporation or any Subsidiary or the right to remain as a director of or a Consultant to Corporation or any Subsidiary, as the case may be, nor does it interfere in any way with the right of Corporation or a Subsidiary to terminate such person's employment or to remove such person as a Consultant or as a director at any time for any reason, or for no reason, with or without cause.
d.
Restriction on Transfer. No Award (other than Restricted Shares after they Vest) will be transferable other than by will or the laws of descent and distribution and each Award will be exercisable (if exercise is required), during the lifetime of the Participant, only by the Participant or, in the event the Participant becomes legally incompetent, by the Participant's guardian or legal representative. Notwithstanding the foregoing, any Award may be surrendered to the Corporation pursuant to Section 6.5(g).
e.
Termination of Continuous Service. The terms and conditions under which an Award may be exercised, if at all, after a Participant's termination of Continuous Service will be determined by the Committee and specified in the applicable Award Agreement.
f.
Change in Control. The Committee, in its discretion, may provide in any Award Agreement that:
i.
In the event of a Change in Control, all or a specified portion of the Award (to the extent then outstanding) will become immediately Vested in full to the extent not previously Vested. Any such acceleration of Award Vesting must comply with applicable statutory and regulatory requirements. A Participant will be entitled to decline the accelerated Vesting of all or any portion of his or her Award, if he or she determines that such acceleration may result in adverse tax consequences to him or her; and
ii.
In the event the Board approves a proposal for: (1) a merger, exchange or consolidation transaction in which Corporation is not the resulting or surviving corporation (or in which Corporation is the resulting or surviving corporation but becomes a subsidiary of another corporation); (2) the transfer of all or substantially all the assets of Corporation; (3) a sale of 50 percent or more of the combined voting power of Corporation's voting securities; or (4) the dissolution or liquidation of Corporation (each, a "Transaction"), the Committee will notify Participants in writing of the proposed Transaction (the "Proposal Notice") at least 30 days prior to the effective date of the proposed Transaction. The Committee may, in its sole discretion, and to the extent possible under the structure of the Transaction, select one of the following alternatives for treating outstanding Awards under the Plan:
A.
The Committee may provide that outstanding Awards will be converted into or replaced by Awards of a similar type in the stock of the surviving or acquiring corporation in the Transaction. The amount and type of securities subject to and the exercise price (if applicable) of the replacement or converted Awards will be determined by the Committee based on the exchange ratio, if any, used in determining shares of the surviving corporation to be issued to holders of Shares of Corporation. If there is no exchange ratio in the Transaction, the Committee will, in making its determination, take into account the relative values of the companies involved in the Transaction and such other factors as the Committee deems relevant. Such replacement or converted Awards will continue to Vest over the period (and at the same rate) as the Awards which the replacement or converted Awards replaced, unless determined otherwise by the Committee;
B.
The Committee may provide a 30-day period prior to the consummation of the Transaction during which all outstanding Awards will tentatively become fully Vested, and upon

A-6

consummation of such Transaction, all outstanding and unexercised Awards will immediately terminate. If the Committee elects to provide such 30-day period for the exercise of Awards, the Proposal Notice must so state. Participants, by written notice to Corporation, may exercise their Awards and, in so exercising the Awards, may condition such exercise upon, and provide that such exercise will become effective immediately prior to, the consummation of the Transaction, in which event Participants need not make payment for any Common Stock to be purchased upon exercise of an Award until five days after written notice by Corporation to the Participants that the Transaction has been consummated (the "Transaction Notice"). If the Transaction is consummated, each Award, to the extent not previously exercised prior to the consummation of the Transaction, will terminate and cease being exercisable as of the effective date of such consummation. If the Transaction is abandoned, (1) all outstanding Awards not exercised will continue to be Vested and exercisable, to the extent such Awards were Vested and exercisable prior to the date of the Proposal Notice, and (2) to the extent that any Awards not exercised prior to such abandonment have become Vested and exercisable solely by operation of this Section 6.5(f)(ii), such Vesting and exercisability will be deemed annulled, and the Vesting and exercisability provisions otherwise in effect will be reinstituted, as of the date of such abandonment; or
C.
The Committee may provide that outstanding Awards that are not fully Vested will become fully Vested subject to Corporation's right to pay each Participant a cash amount (determined by the Committee and based on the amount, if any, being received by Corporation's stockholders in the Transaction) in exchange for cancellation of the applicable Award.

Unless the Committee specifically provides otherwise in the Change in Control provision for a specific Award Agreement, Awards will become Vested as of a Change in Control Date only if, or to the extent, such acceleration in the Vesting of the Awards does not result in an "excess parachute payment" within the meaning of Section 280G(b) of the Code. The Committee, in its discretion, may include Change in Control provisions in some Award Agreements and not in others, may include different Change in Control provisions in different Award Agreements, and may include Change in Control provisions for some Awards or some Participants and not for others.

g.
Payment of Purchase Price and Withholding. The Committee, in its discretion, may include in any Award Agreement a provision permitting the Participant to pay (x) the purchase or option exercise price, if any, for the Shares or other property issuable pursuant to the Award, or (y) the Participant's federal, state, or local tax withholding obligations with respect to such issuance (which in no event may exceed the amount calculated based on the maximum individual tax rates in the jurisdiction applicable to the Participant), in whole or in part, by one or more of the following methods; provided, however, that the availability of any one or more methods of payment may be suspended from time to time if the Committee determines that the use of such payment method would result in adverse financial accounting treatment for the Corporation or a violation of laws or regulations applicable to the Corporation:
i.
By delivering cash or a check;
ii.
By delivering previously owned Shares (excluding Restricted Shares that have not Vested);
iii.
By reducing the number of Shares or other property otherwise Vested and issuable pursuant to the Award (other than Awards of ISOs);
iv.
In the event Shares are publicly traded, by delivery (in a form approved by the Committee) of an irrevocable direction to a securities broker acceptable to the Committee (subject to the provisions of any applicable statute or rule), to sell Shares subject to the Award and to deliver all or a part of the sale proceeds to Corporation; or
v.
In any combination of the foregoing or in any other form approved by the Committee.

Shares withheld or surrendered as described above will be valued based on their Fair Market Value on the date of the transaction. Any Shares withheld or surrendered with respect to a Reporting Person will be subject to such additional conditions and limitations as the Committee may impose to comply with the requirements of the Exchange Act.

h.
Minimum Vesting Period. No Award may Vest in whole or in part before the one-year anniversary of the Grant Date; provided that the Committee may grant Awards without regard to the foregoing minimum Vesting requirement with respect to a maximum of five percent of the available share reserve authorized for issuance under the Plan pursuant to Section 4.2; and provided, further, that the foregoing restriction does not apply to the Committee’s discretion to provide for acceleration of Vesting of any Award pursuant to Section 3.3(h), including in cases of retirement, death, Disability or a Change in Control, in the terms of the Award or otherwise.

A-7

i.
Service Periods. At the time of granting an Award, the Committee may specify, by resolution or in the Award Agreement, the period or periods of service performed or to be performed by the Participant in connection with the grant of the Award.
j.
Clawback/Recovery. All compensation pursuant to Awards granted under the Plan will be subject to recoupment as required (i) by the Sarbanes-Oxley Act of 2002 or other applicable law or (ii) by any clawback policy that the Corporation is required or the Board determines to adopt, including under the listing standards, if any, of any national securities exchange or association on which the Corporation's securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. In addition, the Committee may impose such other clawback, recovery, or recoupment provisions in an Award Agreement as the Committee determines necessary or appropriate in its sole discretion, including without limitation in the event the Participant accepts employment with a competitor of the Corporation or otherwise competes with the Corporation. No recovery of compensation under such a clawback policy will be an event giving rise to a right to resign for "good reason" or "constructive termination" (or similar term) under any agreement with the Corporation or a Subsidiary.

6.6 Performance Goals. In the event an Award is intended to be performance-based, the Committee will establish Performance Goals for each Performance Period on the basis of such criteria and to accomplish such objectives as the Committee may from time to time select. Performance Goals may be based on (a) performance criteria for the Corporation, a Subsidiary, an operating group, or a branch, (b) a Participant's individual performance, or (c) a combination of both. Performance Goals may include objective and subjective criteria. During any Performance Period, the Committee may adjust the Performance Goals for such Performance Period as it deems equitable in recognition of unusual or nonrecurring events affecting the Corporation, changes in applicable tax laws or accounting principles, or such other factors as the Committee may determine in its sole discretion. Prior to the payment of any Award intended to be performance-based, the Committee must certify, which certification shall be documented in writing, that applicable Performance Goals and any of the material terms thereof were, in fact, satisfied.

6.7 Maximum Awards to Non-Employee Board Directors. Notwithstanding anything to the contrary in this Plan, the value of all Awards awarded under this Plan plus all other cash compensation paid by the Corporation to any Non-Employee Board Director in any calendar year shall not exceed a total of $400,000. For the purpose of this limitation, the value of any Award shall be its grant date fair value, as determined in accordance with ASC 718 or any successor provision but excluding the impact of estimated forfeitures related to service-based vesting provisions.

ARTICLE 7
OPTIONS

7.1 Types of Options. Options granted under the Plan may be in the form of Incentive Stock Options or Nonqualified Options. The grant of each Option and the Award Agreement governing each Option will identify the Option as an ISO or an NQO. In the event the Code is amended to provide for tax favored forms of stock options other than or in addition to Incentive Stock Options, the Committee may grant Options under the Plan meeting the requirements of such forms of options. ISOs may not be awarded unless the Plan is approved by stockholders within 12 months of adoption of the Plan.

7.2 General. All Options will be subject to the terms and conditions set forth in Article 6 and this Article 7 and Award Agreements governing Options may contain such additional terms and conditions, not inconsistent with the express provisions of the Plan, as the Committee deems desirable.

7.3 Option Price. Each Award Agreement for Options will state the option exercise price per Share of Common Stock purchasable under the Option, which may not be less than 100 percent of the Fair Market Value of a Share on the Grant Date for all Options.

7.4 Option Term. The Award Agreement for each Option will specify the term of each Option as determined by the Committee; provided, however, that the term may not exceed 10 years from the Grant Date of such Option.

7.5 Time of Exercise. The Award Agreement for each Option will specify, as determined by the Committee:

a.
The time or times when the Option becomes Vest and exercisable and whether the Option becomes Vested in full or in graduated amounts based on: (i) Continuous Service over a period specified in the Award Agreement, (ii) satisfaction of Performance Goals or other criteria specified in the Award Agreement, or (iii) a combination of Continuous Service and satisfaction of Performance Goals or other criteria;
b.
Such other terms, conditions, and restrictions as to when the Option may be exercised as determined by the Committee; and

A-8

c.
The extent, if any, to which the Option will remain exercisable after termination of the Participant's Continuous Service.

7.6 Special Rules for Incentive Stock Options. In the case of an Option designated as an Incentive Stock Option, the terms of the Option and the Award Agreement will conform with the statutory and regulatory requirements specified pursuant to Section 422 of the Code, as in effect on the date such ISO is granted, including but not limited to the following requirements:

a.
Limited to Employees. ISOs may be granted only to employees of Corporation or a Subsidiary;
b.
Ten Percent Stockholders. In the case of any ISO granted to a Participant who, as of the Grant Date, possesses more than 10 percent of the total combined voting power of all classes of stock of Corporation or any parent or Subsidiary of Corporation, the option exercise price may not be less than 110 percent of the Fair Market Value of a Share on the Grant Date and the ISO may not remain exercisable after the expiration of five years from its Grant Date; and
c.
$100,000 Annual Limitation. In the event that Options intended to be ISOs are granted to a Participant in excess of the $100,000 annual limitation set forth in Code Section 422(d)(1), the Options will be bifurcated so that the Options will be ISOs to the maximum extent allowable under that limitation and will be NQOs as to any excess over that limitation.

7.7 Restricted Shares. In the discretion of the Committee, the Shares issuable upon exercise of an Option may have restrictions similar to Restricted Awards if so provided in the Award Agreement for the Option.

ARTICLE 8
STOCK APPRECIATION RIGHTS

8.1 General. Stock Appreciation Rights are subject to the terms and conditions set forth in Article 6 and this Article 8 and Award Agreements governing Stock Appreciation Rights may contain such additional terms and conditions, not inconsistent with the express terms of the Plan, as the Committee deems desirable.

8.2 Nature of Stock Appreciation Right. A Stock Appreciation Right is an Award entitling a Participant to receive an amount equal to the excess (or, if the Committee determines at the time of grant, a portion of the excess) of the Fair Market Value of a Share of Common Stock on the date of exercise of the SAR over the base price, as described below, on the Grant Date of the SAR, multiplied by the number of Shares with respect to which the SAR is being exercised. The base price will be designated by the Committee in the Award Agreement for the SAR and may be the Fair Market Value of a Share on the Grant Date of the SAR or such other higher price as the Committee determines. The base price may not be less than the Fair Market Value of a Share on the Grant Date of the SAR.

8.3 Exercise. A Stock Appreciation Right may be exercised by a Participant in accordance with procedures established by the Committee. The Committee may also provide that a SAR will be automatically exercised on one or more specified dates or upon the satisfaction of one or more specified conditions.

8.4 Form of Payment. Payment upon exercise of a Stock Appreciation Right may be made in cash, in Shares, in other property, or in any combination of the foregoing, or any other form as the Committee may determine.

ARTICLE 9
RESTRICTED AWARDS

9.1 Types of Restricted Awards. Restricted Awards granted under the Plan may be in the form of either Restricted Shares or Restricted Stock Units.

a.
Restricted Shares. An Award of Restricted Shares is an Award of Shares subject to such terms and conditions as the Committee deems appropriate, including, without limitation, a requirement that the Participant forfeit such Restricted Shares back to the Corporation upon termination of the Participant's Continuous Service for specified reasons within a specified period of time or upon other conditions, as set forth in the Award Agreement for such Restricted Shares. Each Participant receiving Restricted Shares will be issued a stock certificate (or other evidence of ownership on the books of the Corporation or the Corporation's duly authorized transfer agent) in respect of such Shares, registered in the name of such Participant, and will execute and deliver to the Corporation a stock power in blank with respect to the Shares evidenced by such certificate, if any.

A-9

b.
Restricted Stock Units. An Award of Restricted Stock Units is an Award of RSUs (with each RSU having a value equivalent to one Share) granted to a Participant subject to such terms and conditions as the Committee deems appropriate, and may include a requirement that the Participant forfeit such RSUs upon termination of Participant's Continuous Service for specified reasons within a specified period of time or upon other conditions, as set forth in the Award Agreement for such RSUs. The Committee will set the terms and conditions of the Award Agreement so that the Award of RSUs will comply with or be exempt from Code Section 409A.

9.2 General. Restricted Awards are subject to the terms and conditions of Article 6 and this Article 9 and Award Agreements governing Restricted Awards may contain such additional terms and conditions, not inconsistent with the express provisions of the Plan, as the Committee deems desirable.

9.3 Restriction Period. Award Agreements for Restricted Awards will provide that the Shares subject to Restricted Awards may not be transferred, and may provide that, in order for a Participant to Vest in such Restricted Awards, the Participant's Continuous Service must not be terminated, subject to relief for reasons specified in the Award Agreement, for a period commencing on the Grant Date of the Award and ending on such later date or dates as the Committee may designate at the time of the Award (the "Restriction Period"). During the Restriction Period, a Participant may not sell, assign, transfer, pledge, encumber, or otherwise dispose of Shares received under a Restricted Award grant. The Committee, in its sole discretion, may provide for the lapse of restrictions in installments during the Restriction Period. Upon expiration of the applicable Restriction Period (or lapse of Restrictions during the Restriction Period where the Restrictions lapse in installments) the Participant will be entitled to settlement of the Restricted Award or portion thereof, as the case may be.

9.4 Forfeiture. If a Participant's Continuous Service is terminated during the Restriction Period for any reason other than reasons which may be specified in an Award Agreement (such as death or Disability), the Award Agreement may require that all non‑Vested Restricted Shares or RSUs previously granted to the Participant be forfeited and, with respect to Restricted Shares, returned to Corporation.

9.5 Settlement of Restricted Awards.

a.
Restricted Shares. Upon Vesting of an Award of Restricted Shares, the restrictive stock legend on certificates, if any, for such Shares noting applicable Restrictions will be removed, the Participant's stock power, if any, will be returned, any stop transfer instructions in the records of the Corporation or its transfer agent will be removed, and the Shares will no longer be Restricted Shares.
b.
Restricted Stock Units. Upon Vesting of an Award of RSUs, a Participant is entitled to receive payment in an amount equal to the aggregate Fair Market Value of the Shares covered by such RSUs at the expiration of the applicable Restriction Period. Payment in settlement of RSUs will be made as soon as practicable following the conclusion of the applicable Restriction Period in cash, in installments, in Restricted Shares, or in unrestricted Shares equal to the number of RSUs, or in any other manner or combination as the Award Agreement approved by the Committee, in its sole discretion, provides. A Participant shall be paid with respect to the Participant's RSUs no later than the last date that causes the payment to constitute a short-term deferral that is not subject to Section 409A, unless the Award Agreement includes terms that comply with Section 409A.

9.6 Rights as a Stockholder. Until the Restrictions have lapsed with respect to Restricted Shares, a Participant will have voting rights as to such Restricted Shares, but cash dividends or dividend equivalents will not be paid or accrued with respect to such Restricted Shares. Stock dividends issued with respect to non-Vested Shares granted under a Restricted Award will be treated as additional Shares covered by the Restricted Award and will be subject to the same Restrictions. A Participant will have no rights as a stockholder with respect to an Award of RSUs until Shares are issued to the Participant in settlement of the Award.

ARTICLE 10
PERFORMANCE SHARE AWARDS

10.1 General. Performance Share Awards are subject to the terms and conditions set forth in Article 6 and this Article 10 and Award Agreements governing Performance Share Awards may contain such additional terms and conditions, not inconsistent with the express terms of the Plan, as the Committee deems desirable.

10.2 Nature of Performance Shares. Each Performance Share shall represent the right of a Participant to receive an actual Share or Share unit having a value equal to one Share.

A-10

10.3 Performance Period. At the time of each Performance Share Award, the Committee shall establish, with respect to each such Award, a Performance Period during which performance shall be measured. There may be more than one Performance Share Award in existence with respect to a given Participant at any one time, and Performance Periods may differ.

10.4 Performance Measures. Performance Shares shall be awarded to a Participant and earned contingent upon the attainment of Performance Goals established in accordance with Section 6.6.

10.5 Payment.

10.5.1 Following the end of the Performance Period, a Participant holding a Performance Share Award will be entitled to receive payment of an amount, not exceeding the maximum value of the Performance Shares, based on the achievement of the Performance Goals for such Performance Period, as determined by the Committee.

10.5.2 Payment of Performance Shares shall be made in cash or Shares, as designated by the Committee in the Award Agreement. Payment shall be made in a lump sum or in installments and shall be subject to such other terms and conditions as shall be determined by the Committee. A Participant shall be paid with respect to the Participant's Performance Shares no later than the last date that causes the payment to constitute a short-term deferral that is not subject to Section 409A, unless the Award Agreement includes terms that comply with Section 409A.

ARTICLE 11
ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, ETC.

11.1 Plan Does Not Restrict Corporation. The existence of the Plan and the Awards granted under the Plan will not affect or restrict in any way the right or power of the Board or the stockholders of Corporation to make or authorize any adjustment, recapitalization, reorganization, or other change in Corporation's capital structure or its business, any merger or consolidation of Corporation, any issue of bonds, debentures, preferred or prior preference stocks ahead of or affecting Corporation's capital stock or the rights thereof, the dissolution or liquidation of Corporation or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding.

11.2 Mandatory Adjustment. In the event of any stock dividend, stock split, reverse stock split, recapitalization, reclassification, or other distribution of Corporation's securities without the receipt of consideration by Corporation, of or on the Common Stock, the Committee shall make proportionate adjustments or substitution to the aggregate number and type of Shares for which Awards may be granted under the Plan, the maximum number and type of Shares which may be sold or awarded to any Participant, the number and type of Shares covered by each outstanding Award, and the base price, exercise price, or purchase price per Share in respect of outstanding Awards.

11.3 Adjustments by the Committee. In the event of any change in capitalization affecting the Common Stock not described in Section 13.2 above, such proportionate adjustments, if any, as the Committee, in its sole discretion, may deem appropriate to reflect such change, will be made with respect to the aggregate number of Shares for which Awards in respect thereof may be granted under the Plan, the maximum number of Shares which may be sold or awarded to any Participant, the number of Shares covered by each outstanding Award, and the base price, exercise price, or purchase price per Share in respect of outstanding Awards. The Committee may also make such adjustments in the number of Shares covered by, and price or other value of, any outstanding Awards in the event of a spin‑off or other distribution (other than normal cash dividends), of Corporation assets to stockholders.

ARTICLE 12
AMENDMENT AND TERMINATION

12.1 Amendment of Plan. The Board at any time, and from time to time, may amend or terminate the Plan; provided that the Plan will terminate 10 years after the Effective Date, if not terminated by the Board on an earlier date. No amendment shall be effective unless approved by the stockholders of the Corporation to the extent stockholder approval is required to satisfy any applicable law or securities exchange listing requirements. At the time of such amendment, the Board shall determine whether such amendment will be contingent on stockholder approval. The Board may, in its sole discretion, submit any other amendment to the Plan for stockholder approval.

12.2 Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide Participants with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options or to the nonqualified deferred compensation provisions of Code Section 409A or to bring the Plan or Awards granted under it into compliance therewith.

A-11

12.3 No Impairment of Rights. Rights under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (a) the Corporation requests the consent of the Participant and (b) the Participant consents in writing. However, an amendment of the Plan that results in a cancellation of an Award where the Participant receives a payment equal in value to the fair market value of the vested Award or, in the case of an Option, the difference between the Fair Market Value and the exercise price for all Shares subject to the Option, shall not be an impairment of the Participant's rights that requires consent of the Participant.

12.4 Amendment of Awards. Subject to Section 12.5, the Committee at any time, and from time to time, may amend the terms of any one or more Awards; provided, however, that if any such amendment impairs a Participant's rights or increases a Participant's obligations under the Participant’s Award or creates or increases a Participant's federal income tax liability with respect to an Award, such amendment shall also be subject to the Participant's consent (provided, however, a cancellation of an Award where the Participant receives a payment equal in value to the fair market value of the Vested Award or, in the case of Vested Options, the difference between the Fair Market Value of the Shares subject to an Option and the exercise price, shall not constitute an impairment of the Participant's rights that requires consent).

12.5 No Repricings or Underwater Buyouts. Except for adjustments made pursuant to Article 13, without the prior approval of the Corporation's stockholders, no Option or SAR granted under the Plan may:

12.5.1 be amended to decrease the exercise price (in the case of an Option) or base price (in the case of a SAR),

12.5.2 be cancelled in exchange for the grant of any new Option or SAR with a lower exercise or base price or any other new Award, or

12.5.3 otherwise be subject to any action that would be treated under accounting rules or otherwise as a "repricing" of such Option or SAR (including a cash buyout or voluntary surrender/subsequent regrant of an underwater Option or SAR).

ARTICLE 13
MISCELLANEOUS

13.1 Tax Withholding. Corporation has the right, prior to and as a condition to settlement of any Award under the Plan, including the delivery or Vesting of Shares or Awards, to require the Participant to remit to the Corporation an amount sufficient to satisfy any federal, state, or local taxes of any kind required by law to be withheld with respect to such settlement or to take such other action as may be necessary in the opinion of Corporation to satisfy all obligations for the payment of such taxes. The recipient of any payment or distribution under the Plan has the obligation to make arrangements satisfactory to Corporation for the satisfaction of any such tax withholding obligations. Corporation will not be required to make any such payment or distribution under the Plan unless such obligations are satisfied.

13.2 Unfunded Plan. The Plan will be unfunded and Corporation will not be required to segregate any assets that may at any time be represented by Awards under the Plan. Any liability of Corporation to any person with respect to any Award under the Plan will be based solely upon any contractual obligations that may be effected pursuant to the Plan. No such obligation of Corporation will be deemed to be secured by any pledge of, or other encumbrance on, any property of Corporation.

13.3 Payments to Trust. The Committee is authorized to cause to be established a trust agreement or several trust agreements whereunder the Committee may make payments of amounts due or to become due to Participants in the Plan.

13.4 Fractional Shares. No fractional Shares will be issued or delivered under the Plan or any Option and Options granted under the Plan will not be exercisable with respect to fractional Shares. In lieu of such fractional Shares, the Corporation will pay an amount in cash equal to the same fraction using the Fair Market Value of a Share of Common Stock.

13.5 Annulment of Awards. Any Award Agreement may provide that the grant of an Award payable in cash is revocable until cash is paid in settlement thereof or that grant of an Award payable in Shares is revocable until the Participant becomes entitled to the certificate (or other evidence of ownership) in settlement thereof. In the event a Participant's Continuous Service is terminated due to Termination for Cause, any Award which is revocable will be annulled as of the date of such Termination for Cause.

13.6 Engaging in Competition with Corporation. Any Award Agreement may provide that, if a Participant's Continuous Service is terminated voluntarily and within a period of time (as specified in the Award Agreement) after the date thereof accepts employment with any competitor of (or otherwise engages in competition with) Corporation, the Committee, in its sole discretion, may require such Participant to return to Corporation the economic value of any Award that is realized

A-12

or obtained (measured at the date of exercise, Vesting, or payment) by such Participant at any time during the period beginning on the date that is six months prior to the date that such Participant's Continuous Service is terminated.

13.7 Other Benefit and Compensation Programs. Payments and other benefits received by a Participant under an Award made pursuant to the Plan are not to be deemed a part of a Participant's regular, recurring compensation for purposes of the termination indemnity or severance pay law of any state or country and will not be included in, or have any effect on, the determination of benefits under any other employee benefit plan or similar arrangement provided by Corporation or a Subsidiary unless expressly so provided by such other plan or arrangements, or except where the Committee expressly determines that an Award or portion of an Award should be included to accurately reflect competitive compensation practices or to recognize that an Award has been made in lieu of a portion of cash compensation. Awards under the Plan may be made in combination with or in tandem with, or as alternatives to, grants, awards, or payments under any other Corporation or Subsidiary plans, arrangements, or programs. The Plan notwithstanding, Corporation or any Subsidiary may adopt such other compensation programs and additional compensation arrangements as it deems necessary to attract, retain, and reward employees and directors for their service with Corporation and its Subsidiaries.

13.8 Securities Law Restrictions. No Shares may be issued under the Plan unless counsel for Corporation is satisfied that such issuance will be in compliance with applicable federal and state securities laws. Certificates for, or other evidence of ownership of, Shares delivered under the Plan may be subject to such stop‑transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange or registered securities association upon which the Common Stock is then listed or quoted, and any applicable federal or state securities laws. The Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

13.9 Continuing Restriction Agreement. Each Participant will, if requested by Corporation and as a condition to issuance of Shares under the Plan upon an Award or exercise of an Award granted under the Plan that results in the issuance of Shares, become a party to and be bound by a stock restriction or other agreement with Corporation containing restrictions on transfer of Shares, including, without limitation, a right of first refusal for the benefit of Corporation, a market stand-off provision, or such other terms as Corporation may reasonably require.

13.10 Governing Law. Except with respect to references to the Code or federal securities laws, the Plan and all actions taken thereunder will be governed by and construed in accordance with the laws of the state of Maryland, without regard to principles of conflicts of laws.
