PROXY STATEMENT

ANNUAL MEETING OF SHAREHOLDERS

APRIL 30, 2026

VOTING INFORMATION

This proxy statement and the accompanying notice of annual meeting and proxy card are being made available, on or about March 20, 2026, to the shareholders of The Hackett Group, Inc. (the “Company” or “Hackett”), in connection with the solicitation of proxies by the Board of Directors of the Company (the “Board”) to be voted at the 2026 Annual Meeting of Shareholders to be held on April 30, 2026 at 11:00 a.m. (local time) at the Company’s headquarters located at 1001 Brickell Bay Drive, 30th Floor, Miami, Florida and any postponement or adjournment thereof.

Your shares will be voted in accordance with the instructions contained on a properly executed proxy card submitted to the Company or in accordance with your instructions submitted via the telephone or Internet.

The Board recommends that you vote:

Executed but unmarked proxies submitted to the Company will be voted in accordance with the Board’s recommendations.

If any other matters are properly brought before the annual meeting, proxies will be voted in the discretion of the proxy holders. The Company is not aware of any such matters that are proposed to be presented at the annual meeting.

On or about March 20, 2026, the Company is mailing to its shareholders a notice containing instructions on how to access this proxy statement and the Company’s 2025 Annual Report and to vote online. The notice also contains instructions on how you can receive a paper copy of your annual meeting materials, including the notice of annual meeting, proxy statement and proxy card. Shareholders receiving this document and accompanying proxy card and Annual Report via the Internet may submit their proxies by telephone or through the Internet as instructed in the notice delivered via U.S. mail. Shareholders receiving this document and accompanying proxy card via U.S. mail may submit a signed proxy card or they may submit their proxy by telephone or through the Internet as instructed on the proxy card. Telephone and Internet proxies must be used in conjunction with, and will be subject to, the information and terms contained on the proxy card. These procedures may not be available to shareholders that hold their shares through a broker, nominee, fiduciary or other custodian. If your shares are held in this manner,

please check your proxy card or contact your broker, nominee, fiduciary or other custodian to determine whether you will be able to vote by telephone or through the Internet.

If you share an address with one or more other shareholders, you may have received notification that you will receive only a single copy of the Annual Report, notice and proxy statement for your entire household unless you have notified us that you wish to continue receiving individual copies. This practice, known as “householding,” is designed to reduce printing and mailing costs. If you would like to revoke your consent to “householding,” or if you are receiving multiple copies at your address and would like to enroll in “householding,” please submit your request to Josie Estevez-Lugo at 1001 Brickell Bay Drive, 30th Floor, Miami, FL 33131 or call us at (305) 375-8005. If you own your shares in “street name,” please contact your broker, bank, trustee, or other intermediary to make your request.

The cost of soliciting proxies in the form enclosed herewith will be borne entirely by the Company. In addition to the solicitation of proxies by mail, proxies may be solicited by directors, officers and regular employees of the Company, without extra remuneration, by personal interviews, telephone or otherwise. The Company will request persons, firms and corporations holding shares in their name or in the names of their nominees, which are beneficially owned by others, to send proxy materials to and obtain proxies from the beneficial owners and will reimburse the holders for their reasonable expenses in doing so.

The securities that may be voted at the annual meeting consist of shares of the Company’s common stock. Each outstanding share of common stock entitles its owner to one vote on each matter as to which a vote is taken at the annual meeting. The close of business on March 13, 2026, has been fixed by the Board as the record date (the “Record Date”) for determination of shareholders entitled to vote at the annual meeting. On the Record Date, 25,220,226 shares of common stock were issued and outstanding and entitled to vote. The presence, in person or by proxy, of at least a majority of the shares of common stock issued and outstanding and entitled to vote on the Record Date is necessary to constitute a quorum at the annual meeting. Shares can be voted only if the shareholder is present in person or represented by proxy. Whether or not you plan to attend in person, you are encouraged to sign and return the enclosed proxy card or vote by telephone or through the Internet as instructed on the proxy card or in the notice mailed to you.

Assuming the presence of a quorum at the annual meeting, the following voting standards will apply to the various proposals:

Abstentions and broker non-votes will be treated as shares that are present in person or represented by proxy at the meeting and entitled to vote for purposes of determining the presence of a quorum at the annual meeting. A “broker non-vote” occurs when a nominee holding shares for a beneficial owner votes on one proposal, but does not vote on another proposal because the nominee does not have discretionary voting power and has not received instructions from the beneficial owner. Abstentions and broker non-votes will not have any effect on the approval of Proposal 1. Because abstentions will be counted for purposes of determining the shares present or represented at the annual meeting and entitled to vote, abstentions will have the same effect as a vote “against” Proposals 2, 3 and 4. Broker non-votes will not have any effect on the approval of Proposals 2, 3 and 4.

The presence of a shareholder at the annual meeting will not automatically revoke the shareholder’s proxy. Shareholders may, however, revoke a proxy at any time prior to its exercise by filing with the Secretary of the Company a written notice of revocation, by delivering to the Company a duly executed proxy bearing a later date or by attending the annual meeting and voting in person. If you submitted your proxy by telephone or through the Internet, you may also revoke it by submitting a new proxy using the same procedures at a later date. The telephone and Internet voting facilities for shareholders of record will close at 1:00 a.m. Central Time on the day of the meeting.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE ELECTION OF THE BOARD NOMINEE AND FOR THE APPROVAL OF PROPOSALS 2, 3 AND 4.

PROPOSAL 1

ELECTION OF DIRECTOR

General

The Company’s articles of incorporation provide that the Board shall consist of no fewer than five directors and no more than fifteen directors. The Company’s bylaws provide that the number of directors, within such limits, shall be determined by resolution of the Board. The Board currently is composed of seven directors. The Board is divided into three classes. One class is elected each year for a term of three years.

One director will be elected at the annual meeting. The Board has nominated John R. Harris, who is an existing director, for the position. If elected, Mr. Harris will serve a three-year term expiring at the annual meeting in 2029. You can find more information about Mr. Harris below.

Unless otherwise instructed on the proxy, it is the intention of the proxy holders to vote the shares represented by each properly executed proxy for the election of the nominee. The Board believes that Mr. Harris will stand for election and will serve if elected. However, if Mr. Harris fails to stand for election or is unable to accept election, proxies will be voted by the proxy holders for the election of such other person as the Board may recommend.

Since this election is not contested, the Board’s nominee for director will be elected only if the votes cast for the nominee’s election exceed the votes cast against the nominee’s election. If Mr. Harris is not re-elected, the Company bylaws provide that he must tender his resignation to the Board. The Nominating and Corporate Governance Committee will then consider such resignation and recommend to the Board whether to accept or reject the resignation. The Board will decide whether to accept or reject any such tendered resignation within 90 days after certification of the election results and will publicly disclose its decision and the rationale therefor. If the resignation is not accepted, the director will continue to serve until his successor is elected and qualified, until there is a decrease in the number of directors or until the director’s earlier resignation or removal. The majority voting provisions for the election of directors apply only to uncontested elections in which the number of nominees does not exceed the number of directors to be elected. In the event of an election in which the number of nominees exceeds the number of directors to be elected, nominees will be elected by a plurality vote.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR”

THE ELECTION OF MR. HARRIS AS DIRECTOR.

Corporate Governance and Other Matters

Board Composition

The Board consists of seven members, of whom five are considered “independent directors” under the listing standards of the Nasdaq Stock Market (“Nasdaq”). The Company’s independent directors are Maria A. Bofill, Richard N. Hamlin, John R. Harris, Robert A. Rivero and Alan T.G. Wix. The Board currently has three standing committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. Each of the Board’s standing committees consist entirely of independent directors.

Leadership Structure

The roles of Chairman of the Board and Chief Executive Officer have been unified since the Company was founded, and the Board believes that the unification of those roles remains appropriate for the Company at this time. The Board believes that its leadership structure both (1) demonstrates to its employees, clients and shareholders that the Company is under strong leadership with a single person setting the tone and having primary responsibility for managing its operations, and (2) provides an effective connection between management’s role of identifying, assessing and managing risks and the Board’s role of risk oversight. The Board believes that Mr. Fernandez has an in-depth knowledge of the issues, opportunities and challenges that the Company faces, and therefore that he is best positioned to develop agendas and highlight issues that ensure that the Board’s time and attention are focused on the most critical matters impacting the Company. The Board has not appointed a “lead independent” director. The Board believes that its current structure with five of its seven members being independent and with each of its standing committees being chaired by and consisting entirely of independent directors, provides effective independent director oversight of the Company’s operations. The Board recognizes that different board leadership structures may be appropriate for companies in different situations and understands that no structure is appropriate for all companies. While the Board intends to review the appropriate leadership structure for the Company from time to time, the Board believes that the Company has been, and continues to be, well-served by its current leadership structure.

The Board’s Role in Strategy Oversight

The Board and management team are focused on maximizing shareholder value and building long-term business success through sound corporate governance and the implementation of Hackett’s strategy. The Board regularly evaluates strategic opportunities to enhance shareholder value.

Each year, the Board undertakes a strategic review of the proposed annual operating plan, which includes business strategy. The strategic review includes an evaluation of how best to leverage and strengthen the Company's strategic differentiators and a thorough assessment of its services portfolio, including merger and acquisition opportunities. As part of this process, the Board also reviews a capital allocation model and human capital plans, including strategic hires, talent management, and talent development priorities. The proposed annual plan is then revised, if necessary, and approved by the Board. On a quarterly basis, the Board monitors execution of the annual plan and considers any adjustments as required. The annual plan may also be reviewed and revised by the Board as needed throughout the year to reflect changing conditions or new opportunities.

The Board’s Role in Risk Oversight

The Board is responsible for overseeing the Company’s management of the significant risks facing the business, including properly safeguarding the Company’s assets, maintaining appropriate financial and other internal controls, complying with applicable laws and regulations, and implementing proper corporate governance practices. Risks are considered in all business decisions and in connection with the development of the Company’s business strategy. The Board as a whole is responsible for reviewing and approving the Company’s annual operating plan. In connection with that review, the Board typically inquires of management as to the greatest areas of risk associated with the annual operating plan and the Company’s operating model taken as a whole and evaluates whether these risks are appropriately mitigated. In addition, the Board’s committees, which meet regularly and report back to the Board, play significant roles in carrying out the Board’s risk oversight function. Company management also plays an important role in connection with risk management through the implementation and evaluation of effective internal controls and other internal processes.

The Board delegates to the Audit Committee responsibility for assisting the Board with several risk oversight functions, including oversight of those items listed below under “Audit Committee”.

The Board delegates to the Compensation Committee responsibility for assisting the Board in the oversight of risks related to the Company’s compensation programs. The Compensation Committee is charged with understanding the risks and rewards associated with the Company’s compensation philosophy and ensuring that its various compensation programs are aligned with the Company’s goals and objectives.

The Board delegates to the Nominating and Corporate Governance Committee authority to develop and implement the Company’s director nomination guidelines and to recommend nominees for election, ensuring that the Board contains the appropriate mix of experience, qualifications, attributes and skills necessary to effectively exercise its oversight function. The Nominating and Corporate Governance Committee also is responsible for developing and implementing the Company’s corporate governance guidelines and for considering social responsibility, environmental and sustainability matters.

Audit Committee

The Audit Committee reviews, acts on, and reports to the Board with respect to various auditing and accounting matters. The Audit Committee is directly responsible for the appointment, compensation, evaluation, retention and oversight of the Company’s independent registered public accounting firms. The primary functions of the Audit Committee are to assist the Board in its responsibility for oversight of:

The Audit Committee performs all functions required of audit committees of public companies under applicable laws, rules and regulations and the requirements of the Nasdaq.

The current members of the Audit Committee are Messrs. Hamlin (Chairman), Harris, Rivero and Wix and Ms. Bofill. The Board has determined that each current member of the Audit Committee is independent under the

Nasdaq’s listing standards and the SEC’s heightened independence requirements for members of audit committees. The Board has determined that Mr. Hamlin, Mr. Rivero and Ms. Bofill are “audit committee financial experts”, as that term is defined under SEC rules.

The Audit Committee is governed by a written charter. A copy of the charter can be found on the Company’s website at https://www.thehackettgroup.com/governance/. References to the Company website included in this proxy statement are provided solely for convenience purposes. Content on the Company website is not, and shall not be deemed to be, part of this proxy statement or incorporated herein or into any of its other filings with the SEC. (For further information on the Audit Committee, see the “Report of the Audit Committee” on page 42 in this proxy statement).

Compensation Committee

The Compensation Committee is responsible for determining the compensation of the Company’s executive officers and approving executive compensation and human resource programs for the Company. The Compensation Committee determines the compensation of the Company’s CEO. In addition, the Compensation Committee has the following authority and responsibilities:

The current members of the Compensation Committee are Messrs. Harris (Chairman), Hamlin, Rivero and Wix and Ms. Bofill. The Board has determined that the current members of its Compensation Committee are independent under the Nasdaq’s listing standards.

For 2025, as in prior years, the Company conducted, and the Compensation Committee reviewed, a risk assessment of its compensation programs and considered the extent to which its compensation policies and practices influence the behaviors of its executives and other employees with respect to taking business risks that could affect the Company. The Company believes that none of its compensation policies and practices are reasonably likely to have a material adverse effect on the Company.

The Compensation Committee is governed by a written charter. A copy of the charter can be found on the Company’s website at https://www.thehackettgroup.com/governance/. (For further information on the Compensation Committee, see the “Compensation Committee Report” on page 13 in this proxy statement).

Nominating and Corporate Governance Committee

The current members of the Nominating and Corporate Governance Committee are Messrs. Wix (Chairman), Hamlin, Harris and Rivero and Ms. Bofill.

The Nominating and Corporate Governance Committee selects and must approve all candidates to stand for election as directors. Pursuant to the Company’s bylaws, other candidates may also be nominated by any shareholder, provided each such other nomination is submitted in accordance with the procedures set forth in the Company's bylaws. For a discussion of the requirements for including information with respect to a shareholder’s nominee in the Company’s proxy statement, see “Shareholder Proposals for the Annual Meeting in 2027” on page 48 of this proxy statement.

The Nominating and Corporate Governance Committee is also responsible for the development and implementation of the Company’s corporate governance guidelines. The Company’s corporate governance guidelines can be found on the Company’s website at https://www.thehackettgroup.com/governance/. The corporate governance guidelines implemented by the Nominating and Corporate Governance Committee contain criteria that the Committee employs to identify and recommend candidates to the Board. These criteria include:

As reflected in the Company’s corporate governance guidelines, the Nominating and Corporate Governance Committee believes that a director candidate should have expertise, skills, knowledge and experience that, when taken together with that of other Board members, will lead to a Board that is effective, collegial and responsive to the needs of the Company.

The Nominating and Corporate Governance Committee is governed by a written charter. A copy of the charter can be found on the Company’s website at https://www.thehackettgroup.com/governance/.

Stock Ownership Guidelines

The Company’s corporate governance guidelines also contain stock ownership guidelines for the Company’s CEO. Pursuant to these guidelines, the Company’s CEO is required to own a number of shares of the Company’s common stock equal in value to six times his annual base salary. The Company’s CEO currently satisfies these requirements. The Company’s CEO is required to purchase shares in the open market to satisfy these guidelines if necessary. Once the guidelines are achieved, the CEO will not be considered to be out of compliance with these guidelines due to fluctuations in the Company’s stock price.

Policy Regarding Hedging and Pledging

The Company’s corporate governance guidelines contain restrictions that prohibit directors, officers and employees of the Company from, directly or indirectly, engaging in hedging transactions with respect to securities of the Company. A hedge transaction is defined as the purchase of any financial instrument (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or any transaction that hedges, offsets, or is designed to hedge or offset, any decrease in the market value the Company’s common stock. The Company’s corporate governance guidelines also contain restrictions that prohibit directors and officers of the Company from pledging securities of the Company as collateral for a loan or otherwise using securities of the Company to secure a debt (e.g., to secure a margin loan) without the prior written approval of the Audit Committee.

Code of Conduct and Ethics

The Company has adopted a Code of Conduct and Ethics that is applicable to all directors, officers and employees of the Company and complies with the requirements of Section 406(c) of the Sarbanes-Oxley Act.

COMPENSATION DISCUSSION AND ANALYSIS

Overview of Compensation Philosophy and Objectives

The Compensation Committee’s objectives relating to compensation are to align the financial interests of management and the Board with those of its shareholders and to attract and retain highly qualified executives. The Company achieves these objectives by linking a substantial portion of each individual’s compensation to the achievement of financial and operational objectives in a particular business unit or the Company as a whole.

The Compensation Committee has adopted a “pay-for-performance” compensation program for the Company’s named executive officers. The program primarily rewards the achievement of annual adjusted diluted net earnings per share targets which, if met, result in the payment of cash bonuses and equity awards, which are in the form of performance-based restricted stock units. The program also rewards the achievement of long-term business objectives based on the continued improvement of operating performance, earnings growth and share value appreciation by vesting these performance-based restricted stock units over a subsequent minimum three-year period. This represents one of the long-term components of the Company's executive compensation programs. This vesting period, during which the value of the Company's common stock can rise or fall based on Company performance, places a premium on the execution of the Company’s long-term strategy and further aligns its executives’ interests with those of the Company's shareholders. The Company’s compensation programs require the Company’s executive officers to focus on the future growth and current profitability of the Company, as well as, on increasing shareholder value.

In September 2024, the Compensation Committee approved the one-time grant of performance-based restricted stock unit awards (the “Stock Price Awards”) to the Company’s named executive officers, and eight other employees, under the Company’s 1998 Stock Option and Incentive Plan (the “Plan”). (See page 16 below for a more detailed discussion of the Stock Price Awards). The Stock Price Awards are designed to incentivize long-term out-performance of the Company’s stock price, aligning the executives’ interests with those of the Company’s stockholders while taking into account the Company’s need to aggressively pivot its capabilities to support generative artificial intelligence (“Gen AI”) related consulting and implementation services and pursue the development of or acquisition of Gen AI software platforms and related capabilities to support and differentiate its offerings. In connection with the grant of the Stock Price Awards, the Compensation Committee determined that annual equity incentive award opportunities for the named executive officers during the three-year performance period of the Stock Price Awards program will be reduced by 50%, as compared to the annual equity incentive award opportunities in the Company’s executive compensation program for 2024. As a result, the value of the 2025 equity awards to named executive officers were 50% less than 2024 and will remain at this level through 2028. The reduction applies to all other participants as well.

The main goals of the Company’s executive compensation program are as follows:

The Company believes that its compensation programs support its business strategies and directly links pay with performance results. The Company continues to observe what it believes to be its directly comparative pay market, which is other strategic consulting and business advisory organizations and professional services firms which are mostly of significantly greater size.

In order to assure that its executive compensation programs are both competitive and appropriate, the Compensation Committee reviews executive compensation periodically to determine whether any adjustments to

specific compensation components should be implemented. In connection with this process, the Compensation Committee primarily considers the value of base salary and incentive cash and equity compensation. These compensation components are even more meaningful since the Company does not contribute to any retirement programs in any form including defined benefit, defined contribution or supplemental retirement plans for its executives.

The Compensation Committee also periodically reviews external market data on executive compensation in order to obtain a general understanding of current compensation practices. In August 2024, the Company engaged PayGovernance, an independent compensation consultant, to perform a comprehensive review of the Company's executive compensation program, including a potential one-time equity grant as part of the Stock Price Awards, taking into account the Company's desire to pivot its capabilities to support Gen AI-related consulting services and solutions. PayGovernance reviewed annual target pay opportunities for top executives at comparable companies of similar size and reviewed one-time awards at select Small and Mid-Cap companies that were clearly distinct from a company's regular compensation program.

The Compensation Committee has determined that the advisors retained or consulted by the Committee are independent and raise no conflict of interest concerns. PayGovernance did not and has not provided any services to the Company other than those services for which they were retained by the Compensation Committee and are not currently providing any services to the Company.

The Elements of Executive Compensation at the Company

Overview

The Company’s annual executive compensation program that applies to its three named executive officers, Messrs. Fernandez, Dungan and Ramirez, rewards the named executive officers for the achievement of exceptional operating results by providing significant incentive opportunities tied to the attainment of specific financial performance goals. The design of the program has been substantially consistent since it was created by the Compensation Committee in 2005 based on recommendations from a nationally recognized executive compensation consulting firm at the time. The Compensation Committee engaged a consultant in 2017 and again in 2024 to review the compensation program. The Compensation Committee continues to believe that its annual compensation program and compensation levels are appropriate for the Company. The program consists of base salaries and cash and equity incentive bonus opportunities that the Company believes are market competitive for companies of similar size within its industry. The Company's annual executive compensation program consists of two primary elements: (1) short-term compensation in the form of annual compensation, consisting of base salaries, annual cash incentive compensation and employee benefits; and (2) long-term incentive compensation in the form of performance-based restricted stock units which, after being earned through the achievement of performance targets, then vest over a three-year period.

Performance-based cash awards and restricted stock awards are tied to the achievement of adjusted diluted net earnings per share targets based on a Board-approved annual operating plan. Adjusted diluted net earnings per share is defined as net income before income from discontinued operations, if applicable, and excludes restructuring charges and asset impairments, acquisition-related adjustments, non-cash stock compensation expense, amortization of intangible assets, non-recurring charges and includes a tax rate based on Generally Accepted Accounting Principles (“GAAP”). Adjusted diluted net earnings per share is based on weighted average common and common equivalent shares outstanding. In addition, the Compensation Committee retains the right to exclude the impact of certain non-recurring events from the adjusted diluted net earnings per share calculation when, in the opinion of the Compensation Committee, inclusion would not accurately reflect the core operating performance of the Company. The Committee believes that adjusted diluted net earnings per share is the best measure of core operating performance for determining incentive compensation.

On an annual basis, the Compensation Committee evaluates and establishes the threshold and target achievement levels for the Company’s annual incentive compensation program for its named executive officers, which consist of its CEO, COO and CFO, which it refers to as “Commence,” “Goal” and “Superior.” If the Company’s performance falls short of the established goals for business growth, then the bonus compensation paid in connection with the program is reduced or no bonuses are paid at all. Payouts are interpolated if results fall

between performance levels and extrapolated for performance exceeding the Superior level. The Company believes the targets established for its named executive officers are challenging. This program has been in effect for 21 years. In two of those years, no bonuses were paid to the named executive officers as the Commence performance target was not achieved. In ten of those years, including for 2025, a bonus was paid based on results which were between the Commence and the Goal targets. Including 2020, during which a modified executive compensation program was utilized in light of the impact of the COVID-19 pandemic on the Company's business, in two of those years, the Goal target was achieved. In seven of those years, over which average adjusted diluted earnings per share growth was 110%, the Company’s performance exceeded the Superior target. Excluding 2010, when adjusted diluted earnings per share growth was 476%, the average adjusted diluted earnings per share growth over the other six years in which Superior targets were achieved was 50%.

The Compensation Committee targets an even balance between the cash and equity incentive award opportunities included in the Company’s annual compensation programs overall, but weights the equity component in the named executive officer compensation program more heavily in the case of its CEO and COO.

Performance-based equity grants issued to employees, other than the Company’s named executive officers, typically vest over a three or four-year period, based on the recipient’s individual compensation program with the exception of two programs designed for the Company’s senior leadership. The first of those programs was introduced in 2020, and vests a portion of the participant’s annual equity opportunity after the conclusion of the compensation year subject to the achievement of a minimal level of Company profitability and the achievement of personal management objectives established for the individual. For 2025, fourteen individuals participated in this program. Mr. Fernandez and Mr. Dungan do not participate in this program. The second of these programs offers the participant the opportunity to receive a significant equity grant if the person achieves an extraordinary long-term financial goal for which the person has three or four years to achieve. The equity grant, if awarded, would vest on the first anniversary of the grant date. Mr. Fernandez, Mr. Dungan and Mr. Ramirez do not participate in this program.

All equity grants, other than those issued upon hiring or for retention purposes, are issued based on the achievement of Company, group or individual performance goals, any combination thereof, or extraordinary individual contribution. Vesting is contingent on continued employment. The Company regards this vesting period as an important retention tool. More importantly, the Company believes that incentive compensation that is paid in the form of equity that vests over three or four years serves as a meaningful long-term incentive, the ultimate value of which is directly correlated to the price of the Company’s common stock at the end of the vesting period. This rewards employees for increasing shareholder value. A heavier weighting on the incentive equity component ties a greater portion of the Company’s CEO and COO’s ultimate compensation to the ability to deliver increased shareholder value over the vesting period. To further ensure the alignment of the CEO’s interests with those of the Company’s shareholders, the Board has adopted stock ownership guidelines that require the CEO to own a number of shares equal in value to six times his annual base salary. The CEO is currently in compliance with these guidelines.

In September 2024, the Compensation Committee approved the Stock Price Awards program which included a one-time grant of performance-based restricted stock unit awards to the Company’s named executive officers, and eight other employees, under the Plan. The Stock Price Awards program is designed to incentivize long-term out-performance of the Company’s stock price, aligning the executives’ interests with those of the Company’s stockholders while taking into account the Company’s need to aggressively pivot its capabilities to support Gen AI-related consulting and implementation services and pursue the development of or acquisition of Gen AI software platforms and related capabilities to support and differentiate its offerings. Additionally, the annual equity incentive award opportunities for the named executive officers during the performance period of the Stock Price Awards program is reduced by 50%, as compared to the annual equity incentive award opportunities in the Company’s executive compensation program for 2024 for compensation years 2025 through 2028 even if the performance hurdles are achieved earlier than that.

The Stock Price Awards are eligible to become earned based on the achievement of three significant stock price hurdles over a performance period from the date of grant through December 31, 2028 and are conditioned upon satisfaction of time-based vesting conditions. The volume weighted average price per share of the Company’s common stock over any 20 consecutive trading days during the performance period must exceed the applicable

stock price hurdle in order for the stock price hurdle to be considered achieved. Notwithstanding the date of achievement of the stock price hurdles during the performance period, the Stock Price Awards subject to the first, second and third stock price hurdles may not vest until the first, second and third anniversary of the grant date, respectively, which requires continued service through such date.

The following table illustrates the amounts of performance-based restricted stock units that can be earned based on achievement of the three stock price hurdles applicable to the Stock Price Awards, which hurdles were established by the Compensation Committee:

The $30 share price hurdle associated with the Stock Price Awards was achieved in the fourth quarter of 2024. One third of the Stock Price Awards issued to Messrs. Fernandez, Dungan and Ramirez vested on September 16, 2025.

As described above, the Compensation Committee approved the Stock Price Awards following a comprehensive review of the Company’s executive compensation program conducted with the Compensation Committee’s independent compensation consultant, taking into account the Company’s desire to pivot its capabilities to support Gen AI-related consulting services and solutions. The Company believes this transition will help it remain competitive and take advantage of the significant shareholder value creation Gen AI can provide.

The Stock Price Awards are designed to further align the interests of the Company’s key executives with those of its stockholders, by incentivizing the stock performance outcomes and exposing executives more directly to the market price of the Company’s common stock, increasing executive stock ownership over time and promoting retention given their potential value. Based on the closing stock price of $25.60 and 27,651,921 shares outstanding on September 13, 2024, achieving the $50 stock price hurdle represents an approximately $675 million increase in the Company’s market capitalization. As of March 13, 2026, the last closing stock price prior to the date of this proxy statement, was $13.85.

Annual Compensation

Annual compensation of the Company’s named executive officers consists of base salaries, annual incentive compensation and employee benefits.

Base Salaries

The salaries payable to the Company’s named executive officers are generally recommended to the Board by the Compensation Committee during the first quarter of each fiscal year. Each of the named executive officers is a party to an employment agreement that establishes a minimum salary level for the named executive officer. The employment agreements do not provide for any guaranteed increases to base salaries. Messrs. Fernandez, Dungan and Ramirez base salaries in 2025 were $900,000, $630,000 and $400,000, respectively. There was no increase in named executive officer base salaries in 2025. The CEO’s, COO’s and CFO’s base salaries were last increased in 2024, 2024 and 2020, respectively.

The Company believes the base salaries it currently pays to its named executive officers are at market competitive levels for companies of similar size within its industry. See the “Summary Compensation Table” on page 22 of this proxy statement and the related footnotes for additional information about base salaries.

Incentive Compensation

The Company’s annual incentive program reflects the Compensation Committee’s belief that a significant portion of the named executive officers’ compensation should be tied to Company performance. For 2025, variable, non-guaranteed performance-based compensation paid to Messrs. Fernandez, Dungan and Ramirez represented 45%, 39%, and 34%, respectively, of their total compensation. The annual incentive component of the Company’s executive compensation program consists of annual performance-based cash incentive awards and performance-based equity incentive grants in the form of restricted stock units of which, if earned based on performance, vests one third annually over a three-year period commencing on the first anniversary of the grant date. These performance-based cash and equity opportunities are tied to the achievement of adjusted diluted net earnings per share targets based on a Board-approved operating plan. Each participant in the Company’s executive compensation program has target cash and equity incentive opportunities expressed as a percentage of salary. Cash and equity payouts are based on the dollar amount of the opportunity earned based on target levels achieved. For the Company's CEO and COO, the equity opportunities have historically been more heavily weighted than the cash opportunities, including in 2025 and for 2026. Performance-based equity incentive awards earned are expressed in a dollar amount and divided by the Company’s share price on the date of grant to calculate the equity incentive grant in the form of restricted stock units, the value of which is ultimately determined by the Company’s stock price on the date of vesting.

Employee Benefits

The named executive officers, like the rest of the Company’s employees, receive certain customary employee benefits. For 2025, these benefits included health, dental and vision coverage, prescription drug plans, life insurance, flexible spending accounts, short-term and long-term disability insurance and a 401(k) plan. The Company covers approximately 60% of the total cost of the health benefits for its U.S.-based employees, including its named executive officers. In other geographies, the Company’s compensation and benefits packages vary by country and are based on market standards, local custom and legal requirements in the jurisdiction. The Company does not provide for any special retirement-related benefits, such as pensions or 401(k) contribution matches, for its senior executives.

Limited Perquisites

The Company provides limited perquisites to its executive officers in amounts which do not exceed $10,000 for any executive officer.

Shareholder “Say on Pay” Vote

The Board and the Compensation Committee regularly evaluate the Company’s executive compensation policies and practices to ensure they appropriately incentivize performance, reinforce accountability, and align executives’ interests with those of our shareholders—particularly during periods when decisive action is required to protect and enhance long‑term shareholder value. As part of this evaluation, the Board and the Compensation Committee consider the results of the annual advisory vote on executive compensation, commonly known as the “say‑on‑pay” vote. At the Company’s 2025 annual meeting of shareholders, approximately 44% of the votes were cast in support of the say‑on‑pay proposal, compared to an average of approximately 98% support since 2020. The Board viewed this outcome as a clear signal to further engage with shareholders and to strengthen the Company’s disclosure regarding the strategic context and objectives underlying the compensation decisions submitted for shareholder approval.

After the 2025 annual meeting, the Company directly reached out to shareholders representing approximately 64.7% of its outstanding common stock and engaged in discussions with shareholders representing approximately 7.3% of its common stock regarding the say‑on‑pay vote. These discussions, led by the CEO and, in one case, the Compensation Committee Chair, reinforced that shareholders sought clearer disclosure connecting the Stock Price Awards to the magnitude of the strategic transformation underway and the Compensation Committee’s objective of incentivizing disciplined execution of a transition it believes is essential to protecting and enhancing long‑term shareholder value.

Additionally, the Company also has an active year‑round shareholder engagement program that provides shareholders with opportunities to raise questions or concerns, including through direct outreach following earnings calls and during investor meetings throughout the year.

Shareholders who responded indicated that the one‑time Stock Price Awards granted in September 2024 (which were disclosed on a Form 8-K filed on September 16, 2024), were a significant factor in their voting decisions, particularly with respect to the strategic rationale for the awards. While shareholders generally recognized that the Company was navigating a period of profound change in the consulting and technology landscape, they indicated that additional context regarding the scale, urgency, and execution risk of the Company’s strategic transformation would have been helpful in better understanding why the Compensation Committee believed it was necessary to provide targeted, performance‑based incentives to ensure its successful execution.

By way of background, beginning in 2023, the Company initiated a fundamental strategic pivot to reposition its business toward Gen AI‑enabled consulting, implementation, and platform‑led offerings in response to what the Board and management viewed as a critical and time‑sensitive inflection point for the industry. This transformation required the rapid design and development of new Gen AI platforms, including the launch of AI XPLR in January 2024; the codification and indexing of the Company’s proprietary intellectual capital into a domain‑specific Gen AI model; extensive retraining and change across the delivery organization; and the identification and acquisition of LeewayHertz, a globally recognized Gen AI engineering organization. These initiatives were executed by the existing leadership team, without the use of outside advisory or banking support, while maintaining financial discipline and continuing to deliver operating results.

In response to this feedback, the Company has taken the following actions:

The Board and the Compensation Committee believe these actions directly address the concerns expressed by shareholders following the 2025 say‑on‑pay vote and demonstrate the Company’s commitment to aligning executive compensation with long‑term shareholder value creation, disciplined pay practices, and robust governance oversight. The Board remains committed to understanding shareholder perspectives and to earning increased support for the Company’s executive compensation program over time.

Executive Compensation Decisions for 2025

Base Salary

The Compensation Committee believes that the base salaries of the Company’s CEO, COO and CFO remained at market competitive levels for companies of similar size within the Company’s industry. The CEO’s, COO’s and CFO’s base salaries were last increased in 2024, 2024 and 2020, respectively.

Incentive Compensation

Each participant in the Company’s executive compensation program has cash and equity incentive opportunities expressed as a percentage of salary that are tied to specified performance targets. For 2025, incentive compensation awarded to Messrs. Fernandez, Dungan and Ramirez in the form of cash and restricted stock units represented 45%, 39%, and 34%, respectively, of their total compensation as reported in the Summary Compensation Table.

At its meeting held in February 2025, the Compensation Committee reviewed and approved the 2025 base salaries and cash and equity incentive plan targets for the Company’s named executive officers as well as the Company’s other senior leaders. The Compensation Committee specifically approved a program for its named executive officers that would pay annual cash and equity bonuses in connection with the achievement of 2025 adjusted diluted earnings per share performance targets. For 2025, the “Commence”, “Goal” and “Superior” targets established by the Compensation Committee were $1.29, $1.77 and $1.85, respectively. For 2024, the “Commence”, “Goal” and “Superior” targets established by the Compensation Committee were $1.24, $1.71 and $1.78, respectively. These targets represented a 10% and 15% improvement over the Company’s prior year actual adjusted diluted net earnings per share results, respectively. Amounts that exceed “Superior” are paid out using the same rate that is utilized between “Goal” and “Superior”. The non-equity (cash) and equity bonus incentive opportunities for the Company's named executive officers at the Commence, Goal and Superior target levels for 2025, as a percentage of base salary, are seen below:

As described above, in September 2024, the Compensation Committee approved the one-time grant of the Stock Price Awards to the Company’s named executive officers. In connection with the Stock Price Awards, the annual equity incentive award opportunities for the named executive officers during the performance period of the Stock Price Awards in the table above reflect a reduction of 50%, which is required to participate in the program, as compared to the annual equity incentive award opportunities in the Company’s executive compensation program for 2024, for compensation years 2025 through 2028 even if the performance hurdles are achieved earlier than that.

2025 Performance Outcomes

In 2025, the Company’s adjusted diluted earnings per share was $1.55, as compared to the Goal target of $1.77. This resulted in performance-based cash and equity bonuses above the “Commence” level payout but below the “Goal” level payout under the Company’s 2025 executive compensation plan. See Appendix A, “Reconciliation of Reported (GAAP) to Adjusted (Non-GAAP) Results” for a reconciliation of adjusted results, including adjusted diluted earnings per share, to reported GAAP results for 2025.

Executive Compensation Decisions for 2026

At meetings held in February 2026, the Compensation Committee reviewed and approved the 2026 base salaries and cash and equity incentive plan targets for the Company’s named executive officers, as well as for the Company’s other senior leaders. Consistent with prior years, the Compensation Committee specifically approved a program for its named executive officers that, in addition to base salaries, would pay annual cash and equity incentive bonuses in connection with the achievement of specified 2026 performance targets. The Compensation Committee chose to retain annual adjusted diluted net earnings per share as the performance target in 2026.

The Company’s Compensation Committee has once again established challenging performance targets for 2026. The Compensation Committee set the annual “Commence,” “Goal” and “Superior” targets from 80%, 110% and 115% of 2025 adjusted diluted earnings per share of $1.55. The non-equity (cash) and equity bonus incentive opportunities for the Company's named executive officers at the Commence, Goal and Superior target levels for 2026, as a percentage of base salary, remains the same as in 2025. As discussed above, in connection with the grant of the Stock Price Awards, the Compensation Committee determined that annual equity incentive award opportunities for the named executive officers during the three-year performance period of the Stock Price Awards program will be reduced by 50% as reflected in the table above, as compared to the annual equity incentive award opportunities in the Company’s executive compensation program for 2024. As a result, the value of the 2026 equity awards to named executive officers were 50% less than 2024 and will remain at this level through 2028. This reduction applies to all other Stock Price Award participants.

For 2026, Mr. Ramirez will also participate in the Company's senior leadership equity program whereby an annual equity opportunity is subject to the achievement of personal management objectives approved by the Compensation Committee.

Timing of Equity Incentive Plan Awards and Discretionary Equity Awards

The Company does not have a program, policy, plan or practice to time equity awards, including option grants, to its named executive officers or directors in coordination with the release of material non-public information. The Company consistently presents to its Compensation Committee for approval all year-end cash and equity bonus awards based on the previous year’s results at the first Compensation Committee meeting of the year. However, the timing of this approval may be changed in the event of extraordinary circumstances. Therefore, neither the Board nor the Compensation Committee take material non-public information into account when determining the timing of equity awards, nor do they time the disclosure of material non-public information for the purpose of impacting the value of executive or director compensation. The Company’s equity plan expressly prohibits the repricing of options and SARs.

Tax and Accounting Considerations and Compensation Deductibility Policy

In evaluating compensation program alternatives, the Compensation Committee considers, among other factors, the potential impact on the Company of Section 162 (m) of the Internal Revenue Code (“Section 162(m)”). Section 162(m) imposes a $1,000,000 per person limit on the annual tax deduction for compensation paid to the Company’s CEO, CFO, and certain other current and former executive officers.

The Compensation Committee, however, believes that it is important for it to retain maximum flexibility in designing compensation programs that are in the best interests of the Company and its stockholders, even if such approach results in certain amounts that may be payable in excess of $1,000,000 to not be deductible under Section 162(m). As a result, the Compensation Committee has approved and reserves the right to approve compensation that does not qualify for deductibility in circumstances it deems appropriate to promote varying corporate goals.

Compensation Recovery

In 2024, the Company adopted a Compensation Recoupment Policy that complies with SEC and Nasdaq rules that require the recovery from its current or former covered officers of any erroneously awarded compensation in the three-year period prior to a restatement. A copy of the Company’s Incentive Compensation Recoupment Policy can be found on the Company’s website at https://www.thehackettgroup.com/governance/.

Insider Trading Policy

The Company has adopted an insider trading policy governing the trading in its securities by directors, executive officers and other employees that is designed to promote compliance with insider trading laws, rules and regulations and applicable Nasdaq standards, which is filed as an exhibit to its Annual Report on Form 10-K for the year ended December 27, 2024.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

The tables below quantify (in U.S. dollars) the potential payments upon termination or a change in control of the Company for each of the named executive officers actively employed by the Company at the end of fiscal year 2025. All amounts are calculated assuming (i) a termination date of December 26, 2025 and (ii) the price per share of the Company’s securities was the closing market price as of that date. These payments are subject to the terms of the employment agreements that are summarized under “Narrative Disclosure to Summary Compensation Table and Plan-Based Awards Table” on page 27 of this proxy statement.

In certain cases, the tax laws deny an income tax deduction for payments that are contingent upon a change in control. Benefits under the employment agreements will be delayed or modified if such delays or modifications are necessary to comply with the rules governing deferred compensation plans under Section 409A of the Internal Revenue Code.

DIRECTOR COMPENSATION

Upon reaching ten years of service on the Board, outside director members receive a restricted stock unit grant equal in number of units to his or her annual service grant for that year. Each of the Company’s outside directors is allowed to elect to defer the receipt of their shares upon vesting for three years, five years or until death, disability or termination of service on the Board.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee consists of Messrs. Harris (Chairman), Hamlin, Rivero and Wix and Ms. Bofill. No current or former member of the Compensation Committee is, or has ever been, an officer or employee of the Company. None of the Company’s directors and none of their family members are employed as an executive of another company where any of the Company’s executives serve on the compensation committee of which the director is an executive.

PAY RATIO

Presented below is the ratio of annual total compensation of the Company's CEO to the annual total compensation of its median employee (excluding its CEO). The ratio presented below is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Securities Exchange Act of 1934 (the "Exchange Act").

In identifying the Company's median employee, the Company's calculation included the base salary for each employee as of December 26, 2025, commissions paid in 2025 and any cash and equity performance and non-performance-based bonus compensation paid or granted to such employees in 2026, based on their performance for fiscal year 2025. Bonus information for 2025 was not available for all employees as of the Record Date as several of the Company's practices conduct performance reviews during the first quarter of the year and approve raises and pay bonuses in April. For employees in these practices the Company estimated 2025 cash and equity bonuses. The amount included for equity performance and non-performance-based bonus compensation grants equaled the fair market value of the shares underlying such grant as of the grant date, however, these grants are subject to time vesting which requires continued employment of the grantee for a period of time ranging from one year, or three to four years. Cash compensation for these purposes included base salary or wages plus overtime pay, cash bonuses, cash commissions and comparable cash elements of compensation in non-U.S. jurisdictions, if applicable, and was calculated using internal payroll and/or tax records. Salaries or wages paid in non-U.S. jurisdictions were converted to U.S. dollars using exchange rates in effect as of December 26, 2025. The Company did not apply any cost-of-living adjustments as part of the calculation.

The Company selected the median employee based on 1,355 full-time and part-time workers who were employed as of December 26, 2025.

The fiscal year 2025 annual total compensation as determined under Item 402 of Regulation S-K for the Company's CEO was $1,628,438. The 2025 annual total compensation as determined under Item 402 of Regulation S-K for the Company's median employee was $77,000. The ratio of the Company's CEO’s annual total compensation to its median employee’s total compensation for fiscal year 2025 is 21 to 1.

The Company has employees in countries with differing labor market characteristics. As such, for purposes of comparability the Company has also calculated the total annual compensation for its median employee in the United States where the Company has 586 employees and generate the majority of its revenue and profitability. The total annual compensation for the median U.S. based employee is $200,000. The ratio of the Company's CEO’s annual total compensation to its median U.S. based employee’s total compensation for fiscal year 2025 is 8 to 1.

As required by Item 402(v) of Regulation S-K, the Company is providing the following information concerning pay versus performance.
