QUESTIONS AND ANSWERS ABOUT VOTING AND THE ANNUAL MEETING

Why am I receiving these materials?

We are providing these proxy materials to holders of shares of our common stock in connection with the solicitation of proxies by the Board to vote at the 2026 Annual Meeting of Stockholders, and at any adjournment(s) or postponement(s) thereof.

When and where is the 2026 Annual Meeting of Stockholders?

Our 2026 Annual Meeting of Stockholders will be held on May 18, 2026, at 1:30 p.m. (Houston, Texas time), in the Auditorium in Centre I of our corporate headquarters at 19001 Crescent Springs Drive, Kingwood, Texas 77339.

Who can vote at the 2026 Annual Meeting of Stockholders?

The Board has fixed April 6, 2026 as the record date for the 2026 Annual Meeting of Stockholders. Stockholders of record at the close of business on April 6, 2026 will be entitled to receive notice of, and vote at, the 2026 Annual Meeting of Stockholders or any reconvened meeting after an adjournment thereof. At the close of business on April 6, 2026, 38,169,182 shares of our common stock, par value $0.01 per share, were outstanding. Each share of our common stock is entitled to one vote upon each of the matters to be voted on at the 2026 Annual Meeting of Stockholders.

What matters will be voted on at the 2026 Annual Meeting of Stockholders, what are my voting choices, and how does the Board recommend that I vote?

At the 2026 Annual Meeting of Stockholders, you will be asked to vote on four proposals:


Proposal	Voting Choices	Board Recommendation
Proposal 1: Election of the four director nominees named in this proxy statement to the Board of Directors	•For •Against •Abstain	FOR the election of all four director nominees

Proposal 2: Advisory vote to approve the Company’s executive compensation (“say-on-pay”)	•For •Against •Abstain	FOR
Proposal 3: Approval of the Second Amendment to the Insperity, Inc. Incentive Plan	•For •Against •Abstain	FOR
Proposal 4: Ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2026	•For •Against •Abstain	FOR

In addition, you may vote on any other business as may properly come before the 2026 Annual Meeting of Stockholders or any adjournments or postponements thereof. The Board is not currently aware of any such other matters.


Insperity			1			2026 Proxy Statement

How many votes are needed to approve each proposal?

The following votes will be required to adopt each proposal:

•Proposal 1: A nominee for director will be elected if the votes cast “FOR” such nominee exceed the votes cast “AGAINST” such nominee.

•Proposal 2: The proposal will be approved if votes cast “FOR” such proposal exceed the votes cast “AGAINST” such proposal.

•Proposal 3: The proposal will be approved if votes cast “FOR” such proposal exceed the votes cast “AGAINST” such proposal.

•Proposal 4: The proposal will be approved if votes cast “FOR” such proposal exceed the votes cast “AGAINST” such proposal.

Broker non-votes result when a broker holding shares for a beneficial owner has not received timely voting instructions on non-routine matters from such beneficial owner and when the broker does not otherwise have discretionary power to vote on a particular matter. Proposals 1, 2, and 3 are considered “non-routine matters” and if you do not provide voting instructions to your broker with respect to these matters, it will result in a broker non-vote with respect to such proposals. Because Proposal 4 is considered a routine matter, your broker can vote your shares in the broker’s discretion with respect to that proposal. Proxies containing broker non-votes are considered “shares present” in determining whether there is a quorum present at the 2026 Annual Meeting of Stockholders but their effect on the outcome of the proposals varies.

In determining the number of votes cast, shares abstaining from voting or not voted on a matter (including broker non-votes) will not be treated as votes cast. Accordingly, proxies containing broker non-votes are not treated as votes cast with respect to the election of directors under Proposal 1 or any of the other proposals on non-routine matters to be voted on at the 2026 Annual Meeting of Stockholders.

What is the difference between holding shares as a “stockholder of record” and having shares held in “street name”?

If your name is registered on our stockholder records as the owner of the shares, then you are the “stockholder of record.” If your shares are held by a bank, broker, or other custodian, then your shares are considered held in “street name.”

If I am a stockholder of record, how can I vote my shares?

If you are a stockholder of record, then you may vote in one of four ways:

•by attending the meeting and voting at the meeting;

•by mail by signing, dating, and returning your proxy in the envelope provided;

•via the Internet at the address listed on your proxy card; or

•by telephone using the toll-free number listed on your proxy card.

For stockholders of record, if you either return your signed proxy or submit your proxy using the Internet or telephone procedures available to you, your shares will be voted as you direct. If you properly execute and return the proxy without indicating a voting direction, then your shares will be voted FOR the election of the nominees listed herein as directors, and FOR Proposals 2, 3, and 4. For stockholders of record, if you do not vote your shares as described above, then your shares will not be voted and will not be counted as present at the 2026 Annual Meeting of Stockholders for the purposes of establishing a quorum.

If my shares are held in street name, how can I vote my shares? Does my bank, broker, or other custodian need my instructions in order to vote my shares?

If your shares are held in street name, then the availability of telephone and Internet voting will depend on the processes of your custodian. Therefore, if your shares are held in street name, we recommend that you follow the voting instructions on the form that you receive from your custodian. If you hold your shares in street name through a custodian, you are


Insperity			2			2026 Proxy Statement

invited to attend the 2026 Annual Meeting of Stockholders, but you must obtain a signed proxy from your custodian in order to vote your shares at the meeting.

If your shares are held in street name and you do not give your custodian direction on how to vote your shares, then your custodian will be unable to vote your shares on most matters. For the 2026 Annual Meeting of Stockholders, your custodian may not vote your shares on Proposal 1 (election of directors), Proposal 2 (advisory approval of executive compensation), or Proposal 3 (approval of the Second Amendment to the Insperity, Inc. Incentive Plan). This would be a “broker non-vote” and these shares will not be counted as having been voted on the applicable proposal; however, your shares would be considered “present” for purposes of establishing a quorum. Assuming a quorum is present, broker non-votes will not affect the outcome of Proposals 1, 2, or 3. Please instruct your custodian so your vote can be counted. With respect to Proposal 4 (ratification of independent auditor), the custodian may exercise its discretion to vote for or against that proposal in the absence of your instruction.

What is the quorum requirement?

A quorum of stockholders is necessary to hold a valid annual meeting. The presence, in person or by proxy, of a majority of the outstanding shares of our common stock is required for a quorum. If a quorum is present at the meeting, under our Bylaws, action on a matter or to elect director nominees shall be approved if the votes cast in favor of the matter or nominee exceed the votes cast opposing the matter or such nominee, as applicable. Your shares will be counted towards the quorum only if you submit a valid proxy, if a valid proxy is submitted on your behalf by your broker, bank or other agent, or if you vote in person at our 2026 Annual Meeting of Stockholders. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the 2026 Annual Meeting of Stockholders may be adjourned to another date.

What if another matter is properly brought before the meeting?

The proxy confers discretionary authority to the persons named in the proxy authorizing those persons to vote, in their discretion, on any other matters properly presented at the 2026 Annual Meeting of Stockholders. The Board is not currently aware of any such other matters.

Who is paying for this proxy solicitation?

We pay the expense of preparing, printing, and mailing proxy materials to our stockholders. In addition to solicitation by mail, our officers or employees (none of whom will receive additional compensation) may solicit the return of proxies by telephone, email, or personal interview. We will also reimburse brokerage houses and other nominees for their reasonable expenses in forwarding proxy materials to beneficial owners of our common stock.

What does it mean if I receive more than one copy of the proxy materials?

If you receive more than one copy of the proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions accompanying each of the proxy materials that you receive to ensure that all of your shares are voted.

Can I change or revoke my vote after submitting my proxy?

If you are a stockholder of record, you may change or revoke your vote by timely: (1) submitting written notice of revocation to the Secretary of the Company at the address for our corporate headquarters, provided above; (2) submitting another proxy card that is properly signed and later dated; (3) submitting a proxy again on the Internet or by telephone; or (4) voting in person at the 2026 Annual Meeting of Stockholders.

If you hold your shares in street name, you may change or revoke your vote by timely: (1) submitting new instructions in the manner provided by your custodian or (2) contacting your custodian to obtain a proxy to vote at the meeting.

How can I find out the results of the voting at the 2026 Annual Meeting of Stockholders?

Preliminary voting results will be announced at our 2026 Annual Meeting of Stockholders. In addition, final voting results will be published in a Current Report on Form 8-K that we expect to file with the U.S. Securities and Exchange Commission (“SEC”) within four business days after the 2026 Annual Meeting of Stockholders. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8‑K to publish the final results.

As a result, beneficial ownership will be attributed to certain subsidiaries of The Vanguard Group, Inc. and The Vanguard Group, Inc. no longer has, or is deemed to have, beneficial ownership of such shares.

PROPOSAL NUMBER 1:

ELECTION OF DIRECTORS

General

In accordance with our Certificate of Incorporation, the members of the Board are divided into three classes. Our Certificate of Incorporation also provides that such classes shall be as nearly equal in number as possible. The terms of office of the Class I, Class II, and Class III directors expire at the Annual Meeting of Stockholders in 2026, 2027, and 2028, respectively. The term of office of each of Timothy T. Clifford, Ellen H. Masterson, Latha Ramchand, and W. Philip Wilmington, who comprise the current Class I directors, expires at the time of the 2026 Annual Meeting of Stockholders, or as soon thereafter as their successors (if any) are elected and qualified. All nominees have consented to be named in this proxy statement and to serve as a director if elected.

Our Certificate of Incorporation and Bylaws provide that the number of directors on the Board shall be fixed from time to time by the Board but shall not be less than three nor more than 15 persons. The number of members constituting the Board is currently fixed at eleven.

Voting; Approval Requirements

All proxies will be voted in favor of the nominees named below unless a stockholder has indicated otherwise. The affirmative vote of a majority of the votes cast by holders of our common stock present in person or by proxy at the 2026 Annual Meeting of Stockholders is required for election of the nominees. Abstentions and broker non-votes will be deemed votes not cast. Under our Bylaws and in accordance with Delaware law, a director’s term extends until his or her successor is duly elected and qualified, or until he or she resigns or is removed from office. Thus, an incumbent director who fails to receive the required vote for re-election at our Annual Meeting of Stockholders would continue serving as a director (sometimes referred to as a “holdover director”), generally until the next Annual Meeting of Stockholders. However, as a condition to being nominated to continue to serve as a director, each incumbent director nominee has submitted an irrevocable letter of resignation that is effective upon and only in the event that (1) he or she fails to receive the required vote; and (2) the Board accepts such resignation. In such an event, the Nominating and Corporate Governance Committee is required to make a recommendation to the Board as to whether the Board should accept the resignation, and the Board is required to decide whether to accept the resignation and to disclose its decision-making process within 90 days from the certification of the election results.

If, at or prior to the 2026 Annual Meeting of Stockholders, any nominee should be unable or decline to serve, the discretionary authority provided in the proxy may be used to vote for a substitute designated by the Board. The Board has no reason to believe that any substitute nominee will be required. No proxy will be voted for a greater number of persons than the number of nominees named herein.

Nominees for Director

The following individuals have been nominated for re-election to the Board as Class I directors with terms expiring at the 2029 Annual Meeting of Stockholders:

These principles inform the broad view of diversity adopted by our Nominating and Corporate Governance Committee when evaluating director candidates. As a result, the Board is comprised of directors with a wide range of perspectives, opinions, and experiences (including directors who have been leaders in start-up companies, public companies, sales organizations, insurance companies, investment banks, HR companies, accounting firms, and business schools), as well as a variety of backgrounds (including two directors from historically underrepresented groups) and other personal factors (including three female directors).

CORPORATE GOVERNANCE

Corporate Governance Guidelines

We have adopted Corporate Governance Guidelines, which include guidelines for, among other things, director responsibilities, qualifications and independence. The Board regularly monitors developments in corporate governance practices and regulatory changes and periodically assesses the adequacy of and modifies our Corporate Governance Guidelines and committee charters as warranted in light of such developments. You can access our Corporate Governance Guidelines in their entirety in the Investor Relations section of our website at www.insperity.com under the Corporate Governance heading. The information on our website is not, and shall not be deemed to be, a part of this proxy statement.

Director Independence

Under the rules of the NYSE, a majority of our directors must be independent. No director qualifies as independent unless the Board affirmatively determines that the director has no material relationship with the Company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company). In evaluating each director’s independence, the Board considered all relevant facts and circumstances, and relationships and transactions between each director, her or his family members or any business, charity or other entity in which the director has an interest or a significant relationship on the one hand, and the Company, its affiliates, or our senior management on the other. As a result of this review, at its meeting held in February 2026, the Board affirmatively determined that all of the Company’s directors are independent, with the exception of Mr. Sarvadi, who is a member of our senior management, and Mr. Rawson, who was a member of our senior management until his retirement in May 2018, whose independence was not considered by the Board.

The Board has considered what types of disclosure should be made relating to the process of determining director independence. To assist the Board in making disclosures regarding its determinations of independence, the Board has adopted categorical standards as contemplated under the listing standards of the NYSE then in effect. Under the rules then in effect, relationships that were within the categorical standards were not required to be disclosed and their impact on independence was not required to be separately discussed, although the categorical standards, by themselves, did not


Insperity			12			2026 Proxy Statement

determine the independence of a particular director. The Board considers all relevant facts and circumstances in determining whether a director is independent. A relationship satisfies the categorical standards adopted by the Board if it:

•is not a relationship that would preclude a determination of independence under Section 303A.02(b) of the NYSE Listed Company Manual;

•consists of charitable contributions made by us to an organization where a director is an executive officer and does not exceed the greater of $1 million or 2% of the organization’s gross revenue in any of the last three years; and

•is not required to be, and it is not otherwise, disclosed in this proxy statement.

In the course of the Board’s determination regarding the independence of those directors under consideration, it considered all transactions, relationships and arrangements in which such directors and the Company were participants or deemed to have an interest.

Selection of Nominees for the Board of Directors

Identification and Evaluation of Candidates for Nomination to the Board of Directors

The Nominating and Corporate Governance Committee may solicit ideas for potential candidates for membership on the Board from a number of sources, including members of the Board, our executive officers, individuals personally known to the members of the Board, research, and search firms. The Nominating and Corporate Governance Committee has authority to select and compensate a third-party executive search firm to help identify candidates, as it deems advisable. In addition, the Nominating and Corporate Governance Committee will consider candidates for the Board submitted by stockholders. Any such submissions should include the candidate’s name and qualifications for Board membership and should be directed to our Corporate Secretary at 19001 Crescent Springs Drive, Kingwood, Texas 77339. Although the Nominating and Corporate Governance Committee does not require the stockholder to submit any particular information regarding the qualifications of the stockholder’s candidate, the level of consideration that the Nominating and Corporate Governance Committee will give to the stockholder’s candidate will be commensurate with the quality and quantity of information about the candidate that the stockholder makes available to the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee will evaluate all candidates identified through the processes described above on the same basis.

In assessing a director candidate, the Nominating and Corporate Governance Committee considers the appropriate balance of experiences, skills and other qualifications required for service on the Board. See “— Director Qualifications” below for detailed information concerning directors’ qualifications. Additionally, the Nominating and Corporate Governance Committee also considers the extent to which a director candidate contributes to the diversity of the Board, with diversity being construed broadly to encompass a director candidate’s perspectives, opinions, experiences, background and other personal factors, including gender, race, ethnicity, and age. Generally, based on this initial evaluation, the chairperson of the Nominating and Corporate Governance Committee will determine whether to interview the candidate and, if warranted, will recommend that one or more members of the Nominating and Corporate Governance Committee, other members of the Board, and senior management, as appropriate, interview the candidate. After completing this evaluation and interview process, the Nominating and Corporate Governance Committee makes a recommendation to the entire Board as to the persons who should be nominated by the Board, and the Board determines the nominees after considering the recommendation of the Nominating and Corporate Governance Committee.

In addition, our Bylaws permit our stockholders to nominate individuals for election as directors at our annual stockholders meeting whether or not such nominee is submitted to and evaluated by the Nominating and Corporate Governance Committee. To nominate an individual for election as a director using this process, a stockholder must follow the procedures described under “Additional Information — Stockholder Director Nominations and Proposals for 2027 Annual Meeting of Stockholders.”

Director Qualifications

The following are core criteria that are expected of each director or nominee:

•high integrity and ethical standards;

•skills and expertise that are complementary to the existing Board members’ skills;


Insperity			13			2026 Proxy Statement

•independence of thought and judgment;

•the ability to dedicate sufficient time, energy and attention to the performance of her or his duties, taking into consideration any service on other public company boards; and

•the ability to represent the interests of all of our stakeholders and not just one particular constituency.

In addition to these core criteria, the Nominating and Corporate Governance Committee regularly assesses the areas of expertise that will promote an effective and high-functioning board and also considers other qualities that it may deem to be desirable, such as demonstrated business judgment, collaborative abilities, training and education, and relationships.

Below are the qualifications, skills, and expertise that the Nominating and Corporate Governance Committee considers critical to the Board’s ability to provide effective oversight of the Company and are directly relevant to our business, strategy and operations. Although a given director or director nominee need not individually possess the experience, skill, or other requisite qualification in all areas, the Nominating and Corporate Governance Committee believes that the Board, as a collective group, should have experience in such areas of expertise. The Nominating and Corporate Governance Committee regularly conducts assessments of the areas of expertise possessed by the current members of the Board and the collective Board, which is considered when developing the desired profile in candidate searches.

The chart that follows illustrates how these qualifications and skills are distributed among our directors and nominees as a collective group.

•Senior Leadership experience as a CEO or as another senior officer demonstrates leadership ability, as well as a practical understanding of complex organizations, processes, corporate culture, and the methods to drive change and growth.

•Industry experience in human capital management, human resources, insurance services, small businesses, or entrepreneurial ventures provides a valuable perspective on the Company’s business strategy, operations, key performance metrics, risks, target markets, competition, and other issues specific to the Company’s business.

•Strategic Planning experience with significant corporate initiatives is valuable in assessing specific plans to capitalize on identified growth opportunities and evaluating the Company’s capital structure and capital allocation.

•Sales & Marketing experience is critical to assisting the Board with oversight of matters relating to a large sales organization, brand development, marketing to businesses, and digital marketing.

•Audit & Financial Planning experience is key to providing oversight to the Company’s internal controls and financial reporting and to critically evaluating metrics that measure our performance.

•Risk Oversight experience contributes to identification, assessment, and prioritization of significant risks facing the Company and facilitates the Board’s role in providing oversight of the Company’s policies and procedures that are designed to manage those risks.

•Corporate Governance experience, including experience with governance principles or environmental, social, and governance initiatives such as sustainability and human capital and workforce engagement, is important to the Board’s understanding of best practices in corporate governance matters and enhancing board effectiveness, and supports the Board’s goals of accountability, transparency and protection of stockholder interests.

•Information, Analytics & Technology experience assists the Board with understanding and oversight of cloud-based, mission-critical solutions, as well as cybersecurity and data privacy matters.

•Service Operations experience is valuable in understanding the issues related to a large service organization that offers business process outsourcing solutions to its clients.


Insperity			14			2026 Proxy Statement

We provide additional information about the qualifications, skills, and expertise of each director in the biographies for the individual directors under the headings of “—Nominees for Director” and “—Directors Not Currently Subject to Election” under Proposal Number 1.

Board of Directors’ Leadership

We do not have a policy with respect to whether the positions of Chairman of the Board and chief executive officer (“CEO”) should be held by the same person or two separate individuals, and believe that it is in the best interest of the Company to consider that question from time to time in the context of succession planning. At this time, the Board believes that it is in the best interest of the Company, and is an appropriate leadership structure, to have the CEO also serve as Chairman of the Board. Combining the CEO and Chairman of the Board roles provides an efficient and effective leadership model that promotes unambiguous accountability and alignment on corporate strategy. Mr. Sarvadi co-founded the Company in 1986 and has served as Chairman of the Board and CEO since 1989. The Board believes that Mr. Sarvadi’s intimate knowledge of the daily operations of, and familiarity with, the Company and industry put him in the best position to provide leadership to the Board on setting the agenda, emerging issues facing the Company and the PEO industry, and strategic opportunities. Additionally, Mr. Sarvadi’s substantial financial stake in the Company creates a strong alignment of interests with other stockholders. Mr. Sarvadi’s combined roles also ensure that a unified message is conveyed to stockholders, employees, and clients.

The position of lead independent director is established by our Corporate Governance Guidelines. Mr. Clifford is currently the lead independent director. The Board reevaluates the lead independent director position annually. The lead independent director has the following responsibilities in addition to the regular duties of a director:

•prepare and set the agenda for and chair executive sessions of the outside directors;

•call or convene executive sessions of the outside directors;

•authority to set the agenda for meetings of the Board;


Insperity			15			2026 Proxy Statement

•preside at all meetings of the Board where the Chairman of the Board is not present or has a potential conflict of interest;

•serve as liaison and facilitate communications between the independent directors and the Chairman of the Board and CEO;

•consult with the Chairman of the Board and CEO on matters relating to corporate governance and performance of the Board; and

•collaborate with the Finance, Risk Management and Audit Committee and with the rest of the Nominating and Corporate Governance Committee on possible director conflicts of interest or breaches of the Corporate Governance Guidelines.

Board of Directors’ Role in Risk Oversight

The Board is responsible for overseeing the Company’s overall risk profile and assisting management in addressing specific risks. Our Enterprise Risk Management Steering Committee (the “ERM Steering Committee”) is responsible for formally identifying and evaluating risks that may affect our ability to execute our corporate strategy and fulfill our business objectives. The ERM Steering Committee employs a disciplined approach to identifying, documenting, evaluating, communicating, and monitoring enterprise risk management within the Company. The ERM Steering Committee is chaired by the Company’s chief financial officer and includes the Company’s general counsel, internal audit director, and other members of management. The ERM Steering Committee reports to the Board and the CEO. The ERM Steering Committee conducts an annual comprehensive risk review of our overall risk profile and analyzes any significant identified risks, including consideration of risks relating to strategic, environmental, social, governance, health and safety, operational, financial, legal, regulatory, and reputational matters, which the ERM Steering Committee then presents and discusses with the Finance, Risk Management and Audit Committee and the entire Board. In addition to the formal annual review, members of the ERM Steering Committee review and provide periodic updates as appropriate regarding our overall risk profile and any significant identified risks to both the Finance, Risk Management and Audit Committee and the entire Board.

During 2025, the ERM Steering Committee completed its annual comprehensive review and update of the Company’s risks. The ERM Steering Committee further reviewed and updated the mitigating factors associated with such risks, and prioritized the identified risks based upon the subjectively determined likelihood of the occurrence and the estimated resulting impact on the Company if the risk occurred.

The Board executes its risk oversight function both directly and through its standing committees and board liaison role, each of which assists the Board in overseeing a part of the Company’s overall risk management. Throughout the year, the Board and each such committee spend a portion of their time reviewing and discussing specific risk factors, and risk assessments are part of major decision making. The Board is kept informed of the risk oversight and related activities of each committee and board liaison through regular reports from such committees. Members of senior management also update the Board and the committees during the year as appropriate to address key risk-related matters, including legal and regulatory developments, the assessment and management of environmental and climate change risks, cybersecurity and data privacy risks, and human capital and workforce engagement.

The Finance, Risk Management and Audit Committee is assigned primary responsibility for oversight of risk assessment with financial implications, as well as those that threaten the long-term sustainability of our business, such as risks associated with cybersecurity, data privacy, environmental (which would include climate change risks), health and safety, and social and governance matters. In its periodic meetings with management, internal auditors, and independent auditors, the Finance, Risk Management and Audit Committee reviews and monitors many factors relating to enterprise risk, including:

•the financial affairs of the Company;

•the integrity of the Company’s financial statements and internal controls;

•the Company’s compliance with legal and regulatory requirements;

•the independent auditor’s qualifications, independence, and performance;


Insperity			16			2026 Proxy Statement

•the performance of the personnel responsible for the Company’s internal audit function and independent auditors; and

•the Company’s policies and procedures with respect to risk management.

The Compensation Committee has primary responsibility to consider material risk factors relating to the Company’s compensation policies and practices.

The Nominating and Corporate Governance Committee monitors governance and succession risks.

The Commonality, Equality, and Cohesion Board Liaison monitors the Company’s human capital-related risks.

As part of its review and approval of our capital budget, compensation, major acquisitions, material contracts, and other similar matters, the Board retains ultimate authority over assessing the risks and their impacts on our business.

Prohibition on Hedging and Pledging of Our Common Stock

We have established strict standards regarding the speculative trading of our common stock. We prohibit employees and directors from engaging in hedging transactions involving our common stock. The Board also adopted a formal policy prohibiting employees and directors from engaging in the significant pledging of shares of our common stock. Any requests to pledge shares or to increase existing amounts of pledged shares are reviewed by the Board, which considers the facts and circumstances and other information the Board deems relevant.

As of April 6, 2026, Mr. Sarvadi had 250,000 shares of our common stock pledged, which represented approximately 17.0% of the shares of our common stock Mr. Sarvadi beneficially owned. After a thorough review, the Board approved Mr. Sarvadi’s pledge of shares based on their determination that the number of shares pledged by him were not significant. In making this determination, the Board considered that the pledged shares did not represent a material portion of the total shares beneficially owned by him, were less than 1% of our total shares outstanding and market capitalization, and also represented an amount that could reasonably be expected to be sold in an orderly manner in a short period of time given the Company’s historic average daily trading volume. The Board also considered Mr. Sarvadi’s significant number of founder’s shares that were not earned as compensation from the Company, his compliance with our stock ownership guidelines and the expectation of the Board that he will continue to comply with the guidelines disregarding the pledged shares, and the purpose of his pledge being unrelated to an attempt to shift or hedge economic risk in owning Company shares. The Board has further authorized Mr. Sarvadi to pledge additional shares provided that, after January 31, 2027, the pledged shares would not exceed 35% of the total shares held by him, as well as that the lending bank to which the additional shares would be pledged should agree that it would not exercise any rights with respect to the pledged shares (including a sale of such shares) at any time that Mr. Sarvadi would be unable to take a similar action under our insider trading or other applicable policies and agree to limits on conducting any sale of pledged shares in an orderly manner designed to minimize adverse impact on the market price of the pledged stock.

In addition, as of April 6, 2026, Mr. Rawson had 75,000 shares of our common stock pledged, which represented approximately 33.1% of the shares of our common stock Mr. Rawson beneficially owned. After a thorough review, the Board approved Mr. Rawson’s pledge of shares based on their determination that the number of shares pledged by him were not significant. In making this determination, the Board considered that Mr. Rawson would continue to hold a material amount of unpledged shares, the pledged shares were less than 1% of our total shares outstanding and market capitalization, and the pledged shares also represented an amount that could reasonably be expected to be sold in an orderly manner in a short period of time given the Company’s historic average daily trading volume. The Board also considered that a significant number of Mr. Rawson’s shares were earned during his employment with the Company and are not related to compensation for service on the Board, his compliance with our stock ownership guidelines (disregarding the pledged shares), the purpose of his pledge being unrelated to an attempt to shift or hedge economic risk in owning Company shares, and the agreement from the lending bank to which the shares are pledged that it would not exercise any rights with respect to the pledged shares (including a sale of such shares) at any time that Mr. Rawson would be unable to take a similar action under our insider trading or other applicable policies.

Code of Business Conduct and Ethics

The Board has adopted a Code of Business Conduct and Ethics (the “Code”) governing the conduct of our directors, officers and employees. The Code, which meets the requirements of Rule 303A.10 of the NYSE Listed Company Manual and Item 406 of Regulation S-K, is intended to promote honest and ethical conduct; full, fair, accurate, timely and understandable disclosure in our public filings; compliance with laws; and the prompt internal reporting of violations of the


Insperity			17			2026 Proxy Statement

Code. Our new employees are required to certify that they have reviewed and understand the Code. In addition, our annual compliance training for all employees reminds them of their obligations under the Code and provides practical examples to foster a deeper understanding of its principles. You can access the Code on our website at www.insperity.com under the Corporate Governance heading in the Investor Relations section. The Finance, Risk Management and Audit Committee has responsibility for oversight of compliance with Code. Changes in and waivers to the Code for our directors, executive officers and certain senior financial officers will be posted on our Internet website within four business days of being approved and will be maintained for at least 12 months.

Stockholder Communications and Engagement

Stockholders and other interested parties may communicate directly with the entire Board or the non-management directors as a group by sending an email to directors@insperity.com. Alternatively, you may mail your correspondence to the Board or non-management directors in care of the Corporate Secretary, 19001 Crescent Springs Drive, Kingwood, Texas 77339. In the subject line of the email or on the envelope, please specify whether the communication is addressed to the entire Board or to the non-management directors.

Unless any director directs otherwise, communications received (via U.S. mail or email) will be reviewed by our Corporate Secretary who will exercise his discretion not to forward to the Board correspondence that is inappropriate such as business solicitations, frivolous communications and advertising, routine business matters (i.e., business inquiries, complaints, or suggestions), and personal grievances.

In addition, members of management, including our Chairman of the Board and CEO, regularly meet with stockholders to review Company strategies, financial and operating performance, and other topics of interest. We share the feedback from these sessions with the Board to help ensure that both the Board and management understand and consider the issues that are important to our stockholders. Please also see “Compensation Discussion & Analysis – Stockholder Advisory Votes” for an additional discussion.

MEETINGS AND COMMITTEES OF THE BOARD OF DIRECTORS

The Board of Directors

Directors are expected to attend all or substantially all Board meetings and meetings of the Committees of the Board on which they serve. Directors are also expected to spend the necessary time to discharge their responsibilities appropriately (including advance review of meeting materials) and to ensure that other existing or future commitments do not materially interfere with their responsibilities as members of the Board. The Board met seven times in 2025. During 2025, all of the members of the Board participated in at least 75% of the meetings of the Board and Committees of which they were members during the period of such director’s service. The Board encourages its members to attend the Annual Meeting of Stockholders. Last year, all eleven of our then-current directors attended the Annual Meeting of Stockholders.

Executive Sessions of the Board of Directors and the Lead Independent or Presiding Director

Our outside directors hold executive sessions at which our management is not in attendance at regularly scheduled Board meetings, and our independent directors hold executive sessions at which only the independent directors are in attendance at least once per year. The lead independent director establishes the agenda and serves as presiding director at the executive sessions. In the absence of a lead independent director, the chairperson of the Nominating and Corporate Governance Committee (if different from the lead independent director) or an independent director designated by the outside directors will preside at meetings of non-management directors. Currently, Mr. Clifford serves as the lead independent director and Ms. Kaufman serves as the chairperson of the Nominating and Corporate Governance Committee.

Committees of the Board of Directors and Board Liaison

The Board has appointed three standing committees: the Finance, Risk Management and Audit Committee; the Compensation Committee; and the Nominating and Corporate Governance Committee. The charters for each of the three standing Committees, which have been adopted by the Board, contain a detailed description of the respective standing committee’s duties and responsibilities and are available on our website at www.insperity.com under the Corporate Governance heading in the Investor Relations section. The Board has reviewed the applicable legal and NYSE standards for independence for members of each of the Finance, Risk Management and Audit Committee; the Compensation Committee; and the Nominating and Corporate Governance Committee, as well as our independence standards for such


Insperity			18			2026 Proxy Statement

Committees, and has determined that the members of each of those Committees of the Board is “independent” under such requirements.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee met three times in 2025. The members of the Nominating and Corporate Governance Committee currently are Ms. Kaufman, who serves as chairperson and Mr. Clifford. The Nominating and Corporate Governance Committee: (1) identifies individuals qualified to become Board members, consistent with the criteria for selection approved by the Board; (2) recommends to the Board a slate of director nominees to be elected by the stockholders at the next Annual Meeting of Stockholders and, when appropriate, director appointees to take office between Annual Meetings of Stockholders; (3) recommends to the Board assignments for membership on the committees of the Board of Directors and the board liaison role; (4) develops and recommends to the Board a set of corporate governance guidelines for the Company; and (5) oversees the evaluation of the Board.

The Finance, Risk Management and Audit Committee met eight times in 2025. The members of the Finance, Risk Management and Audit Committee currently are Ms. Masterson, who serves as chairperson, Mr. Lumelleau, Mr. Morphy, and Dr. Ramchand. The Board has determined that each member of the Finance, Risk Management and Audit Committee is an “audit committee financial expert” as such term is defined in Item 401(h) of Regulation S-K promulgated by the SEC. The Finance, Risk Management and Audit Committee assists the Board in fulfilling its responsibility to oversee the financial affairs, risk management, accounting and financial reporting processes, and audits of financial statements of the Company by reviewing and monitoring: (1) the financial affairs of the Company; (2) the integrity of the Company’s financial statements and internal controls; (3) the Company’s compliance with legal and regulatory requirements; (4) the independent auditor’s qualifications, independence and performance; (5) the performance of the personnel responsible for our internal audit function and the independent auditors; and (6) our policies and procedures with respect to risk management, as well as other matters that may come before it as directed by the Board. The Finance, Risk Management and Audit Committee also reviews risk exposures that threaten the long-term sustainability of the Company’s business, such as risks associated with cybersecurity, data privacy, environmental (which would include climate change risks), health and safety, social and governance matters. In connection with those responsibilities, the Finance, Risk Management and Audit Committee oversees the Company’s process of preparing its annual Corporate Social Responsibility report.

Compensation Committee

The Compensation Committee met nine times in 2025. The members of the Compensation Committee currently are Mr. Clifford, who serves as chairperson, Ms. Kaufman, Mr. Mehl, and Mr. Wilmington. The Compensation Committee: (1) oversees and administers the Company’s compensation policies, plans and practices; (2) reviews and discusses with management the Compensation Discussion and Analysis required by the rules of the SEC; and (3) prepares the annual report required by the rules of the SEC on executive compensation for inclusion in the Company’s annual report on Form 10-K or proxy statement for the Annual Meeting of Stockholders. To carry out these purposes, the Compensation Committee: (1) evaluates the performance of, and determines the compensation for, the CEO and, taking into consideration recommendations made by the CEO, our other executive officers; (2) administers our compensation programs; and (3) performs such other duties as may from time to time be directed by the Board.

Pursuant to the terms of the Insperity, Inc. Incentive Plan, as amended and restated effective May 23, 2023, and as further amended effective May 20, 2025 (the “Incentive Plan”), formerly known as the Insperity, Inc. 2012 Incentive Plan, as amended (the “2012 Incentive Plan”), the Board or the Compensation Committee may delegate authority under the Incentive Plan to the Chairman of the Board or a committee of one or more Board members, respectively, pursuant to such conditions and limitations as each may establish, except that neither may delegate to any person the authority to make awards, or take other action, under the Incentive Plan with respect to participants who may be subject to Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Commonality, Equality, and Cohesion Board Liaison

We are committed to our mission of helping businesses succeed, believing that their prosperity will positively impact the communities we serve. At the heart of our unique company culture is a business concept that we call Commonality, Equality, and Cohesion (or “CEC”). Under the CEC philosophy, we recognize and appreciate the diverse backgrounds and experiences that make each of our team members unique while we collectively drive toward the shared purpose of making an impact for our clients and in our communities. We believe this values-based, people-centric, culture-driven approach


Insperity			19			2026 Proxy Statement

fosters a strong sense of belonging for our employees and creates dynamic employee engagement, which drives a powerful level of care for our clients.

In 2023, the Board created the Commonality, Equality, and Cohesion Board Liaison position to provide independent oversight of, and advice to, Company management with respect to the Company’s CEC efforts and help consider stockholder interests on these matters. Dr. Jones was appointed to this role. As Commonality, Equality, and Cohesion Board Liaison, Dr. Jones provides regular updates to the Board and consults with, and assists, each of the standing committees of the Board as appropriate regarding CEC matters and related risks. This role was also established to reinforce a company-wide commitment to CEC.

Compensation Discussion and Analysis

Introduction

This Compensation Discussion and Analysis (“CD&A”) explains our compensation philosophy, objectives, and strategies and the underlying elements of our compensation programs for our named executive officers (“NEOs”) in 2025. This CD&A also summarizes decisions that the Compensation Committee of the Board (“Compensation Committee”) made regarding these programs and the factors considered in making those decisions.

The following individuals comprised our NEOs for 2025. We had no other executive officers serving at the end of our fiscal year ended December 31, 2025.


Name			Title
Paul J. Sarvadi			Chief Executive Officer and Chairman of the Board
James D. Allison			Executive Vice President of Finance, Chief Financial Officer and Treasurer
A. Steve Arizpe			President and Chief Operating Officer
Christian P. Callens			Senior Vice President of Legal, General Counsel and Secretary

Financial Highlights

During 2025, the Company continued to invest significant human capital and financial resources in support of achieving phase two of our plans to jointly develop, market and sell a new full-service human resources solution for small and midsize businesses with Workday, Inc. (“Workday”), and preparing to launch this new HRScale solution. We believe that this new HRScale solution launching in early 2026 has the potential to positively impact the long-term growth and profitability of the Company. Most of the investment associated with these development efforts were reflected as expenses, resulting in adjusted EBITDA of $131 million, which is lower compared to the prior year. Despite the continued strong execution of our leadership team and employees during 2025 and improved client retention, the continuation of widespread economic uncertainty resulted in a 0.9% increase in our average number of worksite employees (“WSEEs”) paid during 2025 compared to 2024. While growth in average WSEEs paid fell short of expectations, our operating profitability allowed us to maintain our regular quarterly dividend at $0.60 per share, resulting in record regular annual dividends of $2.40 per share.

Consistent with our pay-for-performance approach of tying a significant portion of NEOs compensation to corporate performance, our reduced performance resulted in below target level performance payouts under our annual incentive program, and 0% achievement of the 2025 EBITDA tranches and 2023-2025 relative total shareholder return portion of our performance awards. See “— 2025 Short-Term Incentive Program Performance Results,” “2025 Perfor mance Share Awards under the Long-Term Inc entive Program (“LTIP ”),” “2024 LTIP Awards,” and “2023 LTIP Awards” later in this CD&A for additional details.
