We are monitoringproviding these proxy materials to holders of shares of our common stock in connection with the developments relatedsolicitation of proxies by the Board to vote at the impact2024 Annual Meeting of Stockholders, and at any adjournment(s) or postponement(s) thereof.

The Board has fixed April 4, 2024 as the record date for the 2024 Annual Meeting of Stockholders. Stockholders of record at the close of business on April 4, 2024 will be entitled to receive notice of, and vote at, the 2024 Annual Meeting of Stockholders or any reconvened meeting after an adjournment thereof. At the close of business on April 4, 2024, ________ 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 evolving COVID-19 situation. Asmatters to be voted on at the 2024 Annual Meeting of Stockholders.

Broker non-votes result we may impose additional procedures or limitationswhen a broker holding shares for a beneficial owner has not received timely voting instructions on meeting attendees or may decidenon-routine matters from such beneficial owner and when the broker does not otherwise have discretionary power to hold the meetingvote 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 different location or solely by means of virtual communications. If we decidebroker non-vote with respect to modify the structure of our meeting, we will announce the decision to do so in advance, and details on how to participate will be included insuch proposals. Because Proposal 4 is considered a press release availableroutine 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 2024 Annual Meetings sectionMeeting 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; however, as further explained below, abstentions and shares not voted on a matter (including broker non-votes) will have the same effect as a vote “AGAINST” Proposal 3. Accordingly, proxies containing broker non-votes are not treated as votes cast with respect the election of directors under Proposal 1 or the Investor Relations tabratification of executive pay under Proposal 2 to be voted on our website at www.insperity.com/annualmeetingthe 2024 Annual Meeting of Stockholders. Because Proposal 3 requires the approval of a majority of the outstanding shares of stock, any share of stock that is not voted “FOR” Proposal 3 will have the same effect as a vote “AGAINST” such proposal.

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

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

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 as directors 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 2024 Annual Meeting of Stockholders for the purposes of establishing a quorum and will have the same effect as a vote “AGAINST” Proposal 3.

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 2024 Annual Meeting of Stockholders, your custodian may not vote your shares on Proposal 1 (election of directors), Proposal 2 (advisory approval of frequency of advisory vote on executive compensation), or Proposal 3 (approval of the amendment and restatement of the Company’s Certificate of Incorporation to provide for exculpation of certain officers of the Company from personal liability under certain circumstances as allowed by Delaware law). 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 effect the outcome of Proposals 1 or 2; however, broker non-votes will have the same effect as a vote “AGAINST” Proposal 3. In addition,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.

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 20212024 Annual Meeting of Stockholders. The Board is not currently aware of any such other matters.

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.

Each share of our common stock is entitled to one vote upon each of the matters to be voted on at the 20212024 Annual Meeting of Stockholders.

If a quorum is present atU.S. Securities and Exchange Commission (“SEC”) within four business days after 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.

SECURITY OWNERSHIP

The following table sets forth the number and the percentage of shares of our common stock that were beneficially owned as of April 5, 2021March 1, 2024 by: (1) each person known by us to beneficially own 5% or more of our common stock; (2) all current directors and persons nominated to become directors; (3) each of our executive officers identified in the Summary Compensation Table; and (4) all of our directors, director nominees and executive officers as a group.

PROPOSAL NUMBER 1:

ELECTION OF DIRECTORS

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,II, Class IIIII and Class IIII directors expire at the Annual Meeting of Stockholders in 2023, 20212024, 2025, and 2022,2026, respectively. The term of office of each of Carol.Carol R. Kaufman, John L. Lumelleau, and Paul J. Sarvadi, who comprise the current Class II directors, expires at the time of the 20212024 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 ten.

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 20212024 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 20212024 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.

The following table summarizes the committees of which each director is currently a member:

CORPORATE GOVERNANCE

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 onin the Investor Relations section of our website at www.insperity.com inunder the Corporate Governance section under the Investor Relations tab.heading. The information on our website is not, and shall not be deemed to be, a part of this proxy statement.

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 2021,2024, 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 2018.2018, 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

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:

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

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.

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

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

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:

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 is charged with periodically reviewingconducts an annual comprehensive risk review of our overall risk profile as well asand 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 2020,2023, the ERM Steering Committee completed aits annual comprehensive review and update of the Company’s risks, including strategic, operational, financial, legal, regulatory and reputational 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 all major decision making. The Board is kept informed of each committee’sthe risk oversight and related activities

The Finance, Risk Management and Audit Committee is assigned primary responsibility for oversight of risk assessment with financial implications, includingas well as those that threaten the long-term sustainability of our business.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 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.

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

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 5, 2021,4, 2024, Mr. Sarvadi had 140,000_______ shares of our common stock pledged, which represented approximately 8.3%_______ 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 (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 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 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. If you wish to raise a question or concern or report a violation, including anonymously, to the Finance, Risk Management and Audit Committee, you should visit www.ethicspoint.com (or https://insperity.navexone.com/ on a mobile device) or call the Ethicspoint toll-free reporting hotline at 1-866-384-4277.1-844-606-3529.

EXECUTIVE COMPENSATION

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 2020.2023. This CD&A also summarizes decisions that the Compensation Committee of ourthe Board (“Compensation Committee”) made regarding these programs and the factors considered in making those decisions.

The following individuals comprised our NEOs for 2020:2023:

The continued strong execution of our leadership team and employees following the onsetduring 2023 in spite of COVID-19widespread economic uncertainty and a slow-down in our client hiring activity allowed us to recoverincrease our average number of WSEEsworksite employees (“WSEEs”) paid during 2023 by 5.8% and to pre-pandemic levels and achieve record profitability in 2020 with our$353.6 million of adjusted EBITDA (both of $288.6 million, representing a 15.4% increase compared to 2019. We believe that this performance contributed to the increase inwhich are metrics under our stock priceannual incentive program). Our continued strong level of over 250% from our March 2020 low of $23 andprofitability allowed us to pay record annual dividends of $1.60$2.23 per shareshare.

Our overall compensation philosophy is focused on pay-for-performance. We have set a number of compensation objectives and endeavor to accomplish the philosophy as follows:

Stockholder Advisory Votes

At our 20202023 Annual Meeting of Stockholders, our stockholders approved, in a non-binding advisory vote, the compensation of our NEOs, with over 97%89% of the votes cast in favor of such compensation. The Company’s management conducted stockholder outreach to our largest institutional stockholders prior to our 2023 Annual Meeting of Stockholders regarding our executive compensation programs, the current and prior year’s say-on-pay advisory vote, and the proposal to approve our incentive plan. The feedback received was provided to the Compensation Committee for consideration as part of its ongoing evaluation of our executive compensation programs. The Compensation Committee values the opinions expressed by our stockholders and believes that the level of support at our 2020 support level2023 Annual Meeting of Stockholders demonstrates a strong alignment of our compensation programs with stockholders’ interests.

We provide our NEOs with a mixture of pay linked to company and individual performance. The major elements of our 20202023 annual compensation package for NEOs are summarized in the following chart:

As illustrated in the charts below, following implementation of the compensation changes we made before the onset of COVID-19, as described earlier, approximately 90%88% of the CEO’s target direct compensation and 87%82% of all NEOs target direct compensation, on average, was in the form of performance-basedincentive-based compensation.

Base salary is intended to provide fixed annual compensation to attract and retain talented executive officers. Annual adjustments to base salary are based upon thean annual performance evaluation, market data and other relevant considerations.

Our NEOs base salaries for 2023 were awarded merit salary increases during the first quarter of 2020 as follows:

Variable short-term incentive compensation places a significant portion of executive compensation at risk and is tied to corporate performance. Variable compensation for all executive officers is paid through the Short-Term Incentive Program, a cash and equity incentive program under the stockholder-approved 2012 Incentive Plan. The Short-Term Incentive Program embodies our pay-for-performance philosophy and helps align executive officers’ compensation to the Company’s overall performance.

For 2020,2023, the Compensation Committee set the annual incentive targets as a percentage of each NEO’s base salary and allocated between cash and equity. The 50% increase in the target opportunity (i.e., one-time LTI component) was delivered 100% in performance shares. In addition, our Executive Vice President of Client Services and Chief Operating Officer was promoted to the role of President and Chief Operating Officer during 2019. In recognition of the President’s additional responsibilities for organizational performance and management of business units, and in consideration of peer group market compensation data provided by FW Cook, the Compensation Committee approved the CEO’s recommendation to increase the President’s 2020 annual target bonus opportunity from 100% to 120%.

The Compensation Committee selects corporate performance goals that align with the Company’s business strategy and objectives. The Compensation Committee sets each corporate performance goal to be challenging and rigorous, requiring the attainment of predetermined achievement levels before triggering a payout to the executives. To continue the emphasis on improved unit growth, growth in our human capital management and payroll service solution and profitability, the Compensation Committee tied 100% of the NEOs’ Short-Term Incentive Program payout opportunity to growth in the average number of WSEEs paid, adjusted EBITDAIC (earnings before interest, taxes, depreciation, amortization, and incentive compensation), and growth in the total number of paid employees in our traditional payroll solution. Consistent with prior years, the Compensation Committee chose to exclude incentive compensation from adjusted EBITDA under the Short-Term Incentive Program because any cash payout impacts adjusted EBITDA. For 2020,2023, our annual bonus program was based 50%45% on Adjusted EBITDAadjusted EBITDAIC, 45% on the growth in average number of WSEEs paid, and 50%10% on Growthgrowth in Average WSEEs Paid.the total number of paid employees in our traditional payroll solution.

The executives received bonus payouts in the following amounts based on the weighting for each metric and performance against each objective.

Long-term equity incentives align the interests of our executive officers with those of our stockholders. We believe that long-term incentives enhance retention while rewarding executive officers for achieving long-term performance goals and enhancing stockholder value. Long-term equity incentive awards are made under the stockholder-approved 2012 Incentive Plan. The objectives of the 2012 Incentive Plan are to:

In February 2020,2023, the CEO presented to the Compensation Committee his recommendations for long termlong-term incentive awards for the other executive officers. His recommendations as to the amount and form of awards to be granted were based on a number of factors, including, the importance of each executive officer’s role in the Company’s future business operations, equity pay practices of competitor companies, annual expense to the Company of equity awards, and the Company’s own past practices in granting equity awards. The Compensation Committee then determined and approved the awards for our executive officers, including the CEO, based upon the above noted factors. The Compensation Committee approved 2023 target LTI opportunities for the NEOs that ranged from no increase to a 5.5% increase.
