VOTING SECURITIES AND PRINCIPAL STOCKHOLDERS

The following table sets forth certain information known to us regarding the beneficial ownership of our common stock as of April 24, 2023 (except where otherwise noted) by:

Percentage ownership in the following table is based on 11,133,551 shares of common stock outstanding as of April 24, 2023.

We have determined beneficial ownership in the table in accordance with the rules of the Securities and Exchange Commission (the “SEC”). In computing the number of shares beneficially owned by any person or group or persons and the percentage ownership of that person or group, shares of common stock subject to options held by such person or group or persons that are currently exercisable, or will become exercisable within 60 days after April 24, 2023, are deemed to be beneficially owned by such person and outstanding for the calculation of such person’s percentage ownership and for the percentage beneficially owned by all directors and executive officers as a group. However, we have not deemed these shares to be outstanding for computing the percentage ownership of any other person. To our knowledge, except as set forth in the footnotes following the table, each stockholder identified in the table possesses sole voting and investment power with respect to all shares of common stock shown as beneficially owned by such stockholder. Except as set forth in the footnotes following the table, the address of the beneficial owners is c/o inTEST Corporation, 804 East Gate Drive, Suite 200 Mt. Laurel, New Jersey 08054.

Voting Securities and Principal Stockholders (continued)

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Exchange Act requires directors, executive officers and persons who beneficially own more than 10% of a registered class of our common stock or other equity securities to file with the SEC certain reports of ownership and reports of changes in ownership of our securities. Executive officers, directors and stockholders who hold more than 10% of our outstanding common stock are required by the SEC to furnish us with copies of all required forms filed under Section 16(a). Based solely on a review of this information and/or written representations from these persons that no other reports were required, we believe that, during the prior fiscal year all of our executive officers, directors, and to our knowledge, greater than 10% stockholders, complied with the filing requirements of Section 16(a) of the Exchange Act, except for: Scott Nolen, Joseph McManus and Gregory Martel, who each filed one late Form 3.

In making this statement, we have relied upon the written representations of our directors and officers, and copies of the reports that they have filed with the SEC.

inTEST Corporation | 2023 Proxy Statement – 13

PROPOSAL 1: ELECTION OF DIRECTORS

The Bylaws of inTEST Corporation, as amended and restated effective April 23, 2018 (our “Bylaws”), provide that our Board shall consist of not less than five directors, as determined by the Board from time to time, and that each director shall hold office until the next Annual Meeting of Stockholders and until a successor shall be duly elected and qualified, or until his earlier resignation, retirement or removal. The Board currently consists of five directors.

Listed below are the five nominees for director. The persons designated as proxies in the accompanying proxy card intend to vote “FOR” each such nominee unless a contrary instruction is indicated on the proxy card. If for any reason any such nominee should become unavailable for election, the persons designated as proxies in the proxy card may vote the proxy for the election of another person nominated as a substitute by the Board, if any person is so nominated. We have no reason to believe that any of the nominees will be unable or unwilling to serve if elected, and all nominees have expressed their intention to serve the entire term for which election is sought.

Recommendation of the Board

The Board recommends a vote “FOR” the election of each of the nominees to the Board named below.

Nominees for Election

The names of the persons nominated for election are listed below, together with their ages and certain other information regarding the nominees.

Biographical and Other Information Regarding inTEST’s Director Nominees

Biographical information regarding the business experience of each of our nominees and the primary aspects of each of our nominees’ experience, qualifications, attributes, or skills that led to the conclusion that each of our nominees should serve on our Board is set forth below.

Proposal 1: Election of Directors (continued)

Director Independence

Our Board has determined that each of the directors meet the independence requirements of the listing rules of NYSE American LLC (the “NYSE American Rules”), with the exception of Mr. Grant, who also serves as our President and Chief Executive Officer. In making the foregoing determination, the Board did not identify any matters, transactions, relationships or arrangements that needed to be considered in determining independence of such persons.

Board Leadership Structure

As stated in the Company’s Corporate Governance Guidelines, which can be found on the Company’s website at www.intest.com, the Board believes that it is in the best interests of the Company for the Board to make a determination regarding whether or not to separate the roles of Chairperson of the Board and President and Chief Executive Officer based upon the circumstances. As of the date of this proxy statement, the offices of Chairperson and President and Chief Executive Officer are held by two separate individuals. Joseph W. Dews IV, an independent director, serves as the Chairperson of the Board, and Richard N. Grant, Jr. serves as the President and Chief Executive Officer of the Company. The Board believes the separation of the roles is the most appropriate structure at this time, as it allows the Company’s Chairperson to lead the Board’s responsibilities for reviewing, approving and monitoring fundamental financial and business strategies, allowing the President and Chief Executive Officer to focus primarily on establishing and implementing the Company’s strategic plan and on day-to-day operations.

Proposal 1: Election of Directors (continued)

Risk Oversight

Management is responsible for the day-to-day management of risks that we face, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. Management attends regular meetings of the Board and committees and discusses with the Board or appropriate committees the various risks confronting inTEST, including the operational, legal, market and competitive risks that we face. In addition, the Audit Committee regularly considers financial risks and the steps management has taken to monitor and control such risks. The Compensation Committee provides oversight of risks related to our compensation policies and practices. The Nominating and Corporate Governance Committee oversees risks associated with our corporate governance practices and the independence of directors. The Audit Committee also assists the full Board in overseeing the Company’s risk management practices. During the past year, the Audit Committee reviewed presentations from management covering risk related to critical accounting policies, revenue cycle overview, human resources policies and procedures and SOX 404b readiness.

Transactions with Related Persons

We have not entered into any transactions with a related person since the beginning of our most recently completed fiscal year on January 1, 2022, nor are we otherwise a participant in a current transaction, and no transaction is currently proposed, in which the amount of the transaction exceeds the lesser of $120,000 or 1% of the average of the Company’s total assets at year-end for the last two completed fiscal years and in which a related person had or will have a direct or indirect material interest. For purposes of this paragraph, a related person includes any executive officer, director or nominee for director, any greater than 5% beneficial owner of our common stock, and any immediate family or household member of any of the foregoing.

inTEST Corporation | 2023 Proxy Statement – 17

  RESPONSIBLE CORPORATE GOVERNANCE

Risk Oversight and Board Structure

inTEST is committed to achieving excellence in our corporate governance practices. Our Board of Directors believes that its overriding responsibility is to offer guidance and the benefit of its collective experience to help our management understand the potential risks weighed against the potential opportunities it may confront. Our Corporate Governance Guidelines which set forth our composition considerations, responsibilities and requirements can be found on our website at https://ir.intest.com/corporate-governance.

The Board recognizes its responsibility to determining in the establishment of the Company’s strategy what is the appropriate level of risk for the Company. Fundamental to this process is also ensuring that management not only understands potential risks but is taking the steps needed to understand and manage these risks. To handle these processes, we have currently structured our Board to have three standing Committees: Audit, Compensation, and Nominating and Corporate Governance. Copies of the charters of each of the current committees are posted on our website: www.intest.com.

The Audit Committee is appointed by the Board to assist the Board in fulfilling its oversight responsibilities with respect to the Company’s financial management and controls. The Audit Committee’s primary oversight responsibilities relate to the integrity of our accounting and financial reporting processes, audits of our financial statements, and systems of internal control over financial reporting and accounting matters, and the independence, qualifications, retention, and performance of our independent registered public accounting firm. During 2022, the members of the Audit Committee were Gerald J. Maginnis (Chairperson), Steven J. Abrams and Jeffrey A. Beck. The Board has determined that both Messrs. Maginnis and Beck meet the criteria of an “audit committee financial expert” as that term is defined in Item 401 of Regulation S-K. The Board has also determined that each of the members of the Audit Committee who served as such during 2022, including each of the current members of the Audit Committee, is independent within the meaning of the NYSE American Rules. The Audit Committee held 12 meetings during 2022.

The Compensation Committee is appointed by the Board to review, evaluate, and approve the compensation and benefit programs of our executive officers, to administer our equity-based compensation plans, to review and recommend to the Board changes to our director compensation and to review the annual disclosures regarding the compensation of the Company’s executive officers to be included in inTEST’s annual proxy statement and Annual Report on Form 10-K. During 2022, the members of the Compensation Committee were Jeffrey A. Beck (Chairperson), Joseph W. Dews IV, and Steven J. Abrams. The Board has determined that each of the members of the Compensation Committee is independent within the meaning of the NYSE American Rules, including the stricter requirements of Section 803 of the NYSE American Company Guide, which are not applicable to smaller reporting companies, but which we have adopted as the standard of independence for this Committee. The Compensation Committee held 4 meetings during 2022.

The Nominating and Corporate Governance Committee is appointed by the Board to select the director nominees to be presented for election at future annual meetings of stockholders, to review and assess our corporate governance procedures and to oversee annual evaluations of the Board and director self-assessments. During 2022, the members of the Nominating and Corporate Governance Committee were Steven J. Abrams (Chairperson), Joseph W. Dews IV and Gerald J. Maginnis. The Board has determined that each of the members of the Nominating and Corporate Governance Committee is independent within the meaning of the NYSE American Rules. See “Nominating Procedures” for information regarding the process for identifying and evaluating nominees, procedures for stockholder nominations and director qualifications. The Nominating and Corporate Governance Committee held 2 meetings during 2022.

Board Meetings

During the year ended December 31, 2022, the Board held a total of 8 meetings. Each of our directors attended at least 75% of the aggregate number of meetings of the Board and meetings of any committee of which he was a member, which were held during the time in which he was a director or a committee member, as applicable.

All members of the Board are encouraged, but not required, to attend our annual meeting of stockholders, and may do so virtually, in person or by phone. All of our directors attended the 2022 Annual Meeting of Stockholders, which was held virtually on June 22, 2022.

Responsible Corporate Governance (continued)

Director Stock Ownership Guidelines

On January 14, 2019, the Board approved stock ownership guidelines for non-employee directors (the “Director Ownership Guidelines”). The ownership target under the Director Ownership Guidelines for each non-employee director is five times the annual cash retainer for non-employee directors. Non-employee directors have five years to achieve the ownership target from the later of the date on which the Director Ownership Guidelines were approved or a director joined the Board. Sales of the Company’s stock by non-employee directors are allowed only after each director reaches his ownership target. Such sales of the Company’s stock are allowed, however, prior to the achievement of the ownership target for the purpose of covering taxes due on vesting restricted stock awards and pursuant to any existing trading plans. Each of our non-employee directors as of December 31, 2022 was in compliance with the Director Ownership Guidelines.

Prohibition of Employee, Officer and Director Hedging

The Board believes it is improper and inappropriate for any director, officer or other employee to engage in short-term or speculative transactions involving inTEST’s securities. As such, inTEST’s insider trading policy prohibits directors and employees, including executive officers, from engaging in any hedging or monetization transactions involving inTEST’s securities, purchases on margin or pledging of securities, short sales, buying or selling put or call options and (i) selling equity securities of the Company sooner than six months after last acquiring such equity securities or (ii) buying equity securities of the Company sooner than six months after last selling such equity securities.

Stockholder Communications with the Board

Stockholders who wish to communicate directly with the Board, or with a particular director, may send a letter addressed to our Secretary at 804 East Gate Drive, Suite 200, Mt. Laurel, NJ 08054. The mailing envelope must contain a clear notation indicating that the enclosed letter is a “Stockholder Board Communication” or “Stockholder Director Communication.” All such letters must identify the author as a stockholder and clearly state whether the intended recipients are all members of the Board or just certain specified individual directors. The Secretary will make copies of all such letters and circulate them to the directors addressed. If a stockholder wishes the communication to be confidential, such stockholder must clearly indicate on the envelope that the communication is “confidential.” The Secretary will then forward such communication, unopened, to the directors, or director, specified on the envelope, or if none, to the Chairperson of the Board.

Compensation Procedures

During 2022, the Compensation Committee was comprised, and presently is comprised, solely of independent directors. The Compensation Committee has the authority to delegate any or all of its powers and authority to one or more subcommittees, each subcommittee to consist of one or more members of the Compensation Committee. No such delegation of authority to a subcommittee has occurred. All decisions regarding the compensation of our executive officers are approved by the Compensation Committee.

As a general matter, changes to director compensation are periodically considered by the Compensation Committee and recommended to the Board for approval. Any change in the compensation of any director or any group of directors is approved by a majority of non-interested directors, and, if such recommendation applies to the compensation of all directors, by a majority of the independent directors in addition to a majority of the directors then in office.

In 2021, the Compensation Committee retained Radford, a unit of Aon plc, as its independent compensation consultant to advise it regarding current best practices for executive and director compensation arrangements and to review and make recommendations regarding the amount, type and structure of compensation to be paid to the Company’s executive officers and directors in 2022. At the direction of the Compensation Committee, Radford compares the levels of compensation of the executive officers and directors to market based data available in the Radford Global Technology Survey for similarly sized companies.

The Compensation Committee determined that Radford does not provide any material services to management or the Company, and that Radford does not have any business or personal relationship with any member of the Compensation Committee or management or otherwise have any conflict of interest in performing its services for the Compensation Committee.

inTEST Corporation | 2023 Proxy Statement – 19

Responsible Corporate Governance (continued)

Board Composition and Diversity

Our Nominating and Corporate Governance Committee (which is comprised solely of independent directors) is responsible for developing the general criteria, subject to approval of the Board of Directors, for use in identifying, evaluating and selecting qualified candidates for election, or re-election, to the Board. The Nominating and Corporate assesses the qualifications, expertise, performance and willingness to serve of each current director or candidate.

The Nominating Committee and the Board seek diversity among the members of the Board. The Nominating Committee and the Board believe that considering diversity in terms of experience, skills, industry knowledge, subject matter familiarity as well as gender, race, and national origin creates a Board that can best serve the needs of the Company and its shareholders and are important factors that are considered when identifying individuals for Board membership. In addition, diversity with respect to tenure is important to provide for both fresh perspectives and deep experience and knowledge of the Company. Therefore, we aim to maintain an appropriate balance of tenure across our Directors.

If as a result of its annual assessment of the Board and its composition, or at any other time during the year, the Board determines a need to add a new director with specific qualifications or to fill a vacancy on the Board, a search will be initiated utilizing appropriate staff support, input from other directors, senior management, and outside contacts, consideration of nominees previously submitted by stockholders, and, if deemed necessary or appropriate, retention of a search firm. An initial slate of candidates satisfying the specific qualifications, if any, and otherwise qualifying for membership on the Board, will be identified and reviewed by the Nominating and Corporate Governance Committee and the Board. Candidates will be prioritized, and a determination made as to whether a member of the Nominating and Corporate Governance Committee, another director or member of senior management has a relationship with the preferred candidate and can initiate contacts. If not, contact may be initiated by the Company or the search firm. The Chairperson and one or more members of the Nominating and Corporate Governance Committee or the Board will interview any prospective candidates. Evaluations and recommendations of the interviewers will be shared with all members of the Nominating and Corporate Governance Committee for final evaluation. The Nominating and Corporate Governance Committee will then meet to determine which candidate (or candidates) to select. The Nominating and Corporate Governance Committee will evaluate all nominees for director, including nominees recommended by a stockholder, on the same basis.

Each of the incumbent nominees for director included in this proxy statement was recommended for re-election by the Nominating and Corporate Governance Committee. The full Board, including the President and Chief Executive Officer, unanimously approved all of the nominees for election by the stockholders of the Company, as recommended by the Nominating and Corporate Governance Committee.

Stockholder recommendations with regard to director candidates may be submitted in writing to the Secretary of inTEST for consideration by the Nominating and Corporate Governance Committee. Each such recommendation should include the following information: (i) the name, age, business address and, if known, residence address of each nominee, (ii) the principal occupation or employment of each such nominee, (iii) the number of shares of common stock of inTEST which are beneficially owned by each such nominee, (iv) the qualifications of such nominee for service on the Board, (v) the name and residence address of the proposing stockholder(s), (vi) the number of shares of common stock owned by the proposing stockholder(s), and (vii) such other information as the stockholder making such recommendation believes would be relevant to the consideration of such candidate.

Director candidates must meet certain minimum qualifications, including being at least 21 years old and possessing (1) the ability to read and understand corporate financial statements, (2) relevant business experience and professional skills, (3) high moral character and personal and professional integrity, and (4) the willingness to commit sufficient time to attend to his or her duties and responsibilities as a director of a public corporation. In addition, the Nominating and Corporate Governance Committee may consider a variety of other qualities and skills, including (i) expertise in finance, economics, technology or markets related to the business in which inTEST and its subsidiaries may engage, (ii) the ability to exercise independent decision-making, (iii) the absence of conflicts of interest, (iv) diversity of experience, and (v) the ability to work effectively with other directors in collectively serving the long-term interests of all stockholders. Nominees must also meet any applicable requirements of SEC regulations, state law, our Certificate of Incorporation and our Bylaws. When assessing a candidate, consideration will be given to the effect such candidate will have on the diversity of the Board. Diversity of the Board is evaluated by considering a broad range of attributes, such as background, both geographic and demographic (including, without limitation race, gender and national origin), expertise and experience.

AUDIT COMMITTEE REPORT

The Audit Committee reviewed our audited consolidated financial statements for the year ended December 31, 2022 and met with both management and RSM US LLP (“RSM”), our independent registered public accounting firm, to discuss those financial statements.

EXECUTIVE COMPENSATION

Executive Summary

Since 2016, the Compensation Committee has retained an independent compensation consultant, Radford, to review our executive compensation structure and recommend changes to the structure and manner of compensating our executive officers. In March 2022, as a result of the Compensation Committee’s analysis of information provided by and recommendations from Radford, the Compensation Committee adopted a compensation program for 2022 for our executive officers that aligned executive officer compensation with competitive market practices and specific objectives of the Company in addition to aligning our executive officers’ long-term interests with those of our stockholders by targeting pay for performance. In March 2022, based on the recommendations of Radford and discussions with management, the Compensation Committee approved an executive compensation program based on the following for 2022:

Overview of the Executive Compensation Program

The executive compensation program is designed to reflect the performance of the Company and align the executive officers’ interests with those of our stockholders. To achieve these ends, the executive compensation program consists of three components: base salary, performance-based short-term incentives, and long-term incentives, as more fully described below. While there is no fixed formula, the Compensation Committee seeks an appropriate balance between cash and non-cash compensation, short and long term incentives, at-risk compensation and a mix of various forms of equity compensation. In addition, consistent with market practices, the Compensation Committee believes that executive officers who have greater and more direct impact and ability to influence the Company’s overall performance should receive a significant proportion of equity-based compensation relative to their total compensation, thus seeking to align the executive officers’ incentives and impact with the value they bring to Company-wide performance.

The executive compensation program for 2022 directly addressed the executive compensation of our Chief Executive Officer, Richard N. Grant, Jr., and our Chief Financial Officer, Duncan Gilmour who at the time of its adoption were the Company’s only named executive officers (NEOs). During fiscal year 2022, Scott Nolen became an executive officer. Mr. Nolen’s 2022 executive compensation program is materially consistent in design and structure to the plan established by the Compensation Committee for our other NEOs and, for example, includes base salary, performance-based short-term incentives, and long-term incentives. The base salary and performance-based short-term incentives for Mr. Nolen’s 2022 executive compensation program was established by our Chief Executive Officer, Mr. Grant, prior to his becoming an executive officer, and the long-term incentives were established by the Compensation Committee.

The elements of our executive compensation program are periodically reviewed and analyzed using current publicly available market data, contemporary market trends in the industries in which the Company operates and periodic reviews of compensation and benefit surveys. Although we perform periodic reviews of salary surveys and use compensation consultants to analyze elements of our compensation program, we do not believe that it is appropriate to establish compensation levels based solely on the use of such surveys or analysis or to specifically target any particular market compensation level. This information is used as a market check and as one data point in reviewing our executive compensation program.

Executive Compensation (continued)

The components of our 2022 Executive Compensation Plan were as follows:

Philosophy

The Compensation Committee is committed to the general principle that executive compensation should be commensurate with the Company’s performance and the performance of the individual executive officer. The primary objectives of our executive compensation program are to:

Our pay philosophy is for the total compensation (base salary plus short-term incentive compensation and long-term equity-based compensation) of our named executive officers to be guided by the market median for similarly situated companies.

Underlying our executive compensation program is the philosophy that the interests of our stockholders are best served by a program that includes a significant variable component based on our performance. As a result, our executives have a significant portion of their compensation “at risk,” either through the variability of the short-term incentive portion of the plan, or subject to the movement in the price of the Company’s stock or the Company’s performance through the long- term incentive portion of the plan. Amounts paid under the plan are further subject to repayment or “claw back” as needed to comply with all applicable laws and regulations.

Accordingly, and as more fully described below, the Compensation Committee approved the following compensation arrangements (“2022 Executive Compensation Plan”) for Mr. Grant (our CEO) and Mr. Gilmour (our CFO) for 2022, who, together with Mr. Nolen (our Process Technologies Division President), we refer to as our “named executive officers”. Mr. Nolen’s 2022 executive compensation program was established prior to his becoming an executive officer. Mr. Nolen’s 2022 executive compensation program is materially consistent in design and structure to the plan established by the Compensation Committee for our other NEOs.

Executive Compensation (continued)

The Committee and Mr. Grant (our CEO) believes that the goals for Company-wide and division performance along with the personal goals established under the 2022 Executive Compensation Plan were sufficiently difficult to achieve in order to provide a significant incentive for the participants to improve the Company’s and individual division performance during that year. The Committee and Mr. Grant (our CEO) also believes that such goals did not encourage any of the participants to cause the Company to take excessive risks in connection with achieving the goals and that, by including targets for strategic performance such as those related to development and implementation of a talent development program, the goals were consistent with reducing the Company’s overall risks.

The following matrix shows the payout opportunity for the financial performance portion of the short-term incentive program as a function of target revenue and the targeted financial measures applicable to each NEO.

For the short-term incentive program Mr. Grant did not fully achieve the financial performance goals described above, which were weighted as 60% or the implementation of a talent development program, which was weighted as 20%. Mr. Grant did not achieve the financial performance factors of the three acquisitions completed in 2021, which were weighted as 20%.

As a result, the short-term incentive compensation payout to Mr. Grant for 2022 was as follows:

For the short-term incentive program Mr. Gilmour did not fully achieve the financial performance goals described above, which were weighted as 60% or the achievement of specific objectives, which were weighted as 20%. Mr. Gilmour did not achieve the financial performance factors of the three acquisitions completed in 2021, which were weighted as 20%.

As a result, the short-term incentive compensation payout to Mr. Gilmour for 2022 was as follows:

inTEST Corporation | 2023 Proxy Statement – 27

Executive Compensation (continued)

For the short-term incentive program Mr. Nolen did not fully achieve the financial performance goals described above, which were weighted as 65% or the implementation of a long-term service strategy and program, which was weighted as 5%. Mr. Nolen did not fully achieve the completion of one or more acquisitions in 2022, which was weighted as 20%. Mr. Nolen did successfully implement a talent development program for his division, which was weighted at 10%.

As a result, the short-term incentive compensation payout to Mr. Nolen for 2022 was as follows:

Description of Long-Term Incentive Portion of the 2022 Executive Compensation Plan

As part of Radford’s scope of work, the Compensation Committee sought the consultant’s advice and recommendations on the use of equity-based compensation for the executive officers. With such input from Radford, with respect to Mr. Grant and Mr. Gilmour, the Compensation Committee determined that:

Accordingly, the Compensation Committee decided to compensate Mr. Grant and Mr. Gilmour through the grant of a combination of stock options, shares of time-vested restricted stock and shares of performance-vested restricted stock as set forth above in the 2022 Base Salary and Long-Term Incentive Compensation table.

Similarly, the Compensation Committee decided to compensate Mr. Nolen through the grant of a combination of stock options and shares of time-vested restricted stock as set forth above in the 2022 Base Salary and Long-Term Incentive Compensation table.

Management Stock Ownership Guidelines

On November 4, 2020, the Board approved stock ownership guidelines for named executive officers and certain other members of the Company’s management team (the “Management Ownership Guidelines”). The ownership target under the Management Ownership Guidelines is five times the base salary for the Chief Executive Officer, two times the base salary for the Chief Financial Officer, and 0.5 times the base salary for Vice Presidents and General Managers. On April 26, 2023, the Board approved an amendment to the Management Ownership Guidelines which incorporated ownership targets of five times annual retainer for independent directors and added a one times the base salary for Division Presidents. Such persons have five years to achieve the ownership target from the later of the date on which the Management Ownership Guidelines were approved or when they were hired or promoted to their position. The Chief Executive Officer, Chief Financial Officer, independent directors, Division Presidents, Vice Presidents and General Managers (collectively, the “Covered Executives”) must also remain at or above their required ownership level at the close of trading on April 1 of each year as long as they are employed by, or serve as an independent director of, the Company. Each Covered Executive must retain 50 percent of all net shares (post tax) that vest until the applicable minimum ownership requirement is achieved. If the Covered Executive becomes subject to a higher ownership requirement, the new or higher requirement will apply 30 days after the change and 50 percent of net vested shares should be retained until the new applicable minimum ownership requirement is met.

28 – inTEST Corporation | 2023 Proxy Statement

Executive Compensation (continued)

For purposes of satisfying the minimum ownership requirement, the following will be included:

Unvested shares of performance-based restricted stock, and unexercised options (whether vested or unvested) will not be included in the determination of ownership calculations for purposes of meeting the minimum ownership requirement.

As of December 31, 2022, Messrs. Grant and Nolen were in compliance with the minimum ownership required. Mr. Gilmour did not meet the applicable minimum ownership requirement, as he joined the Company in June 2021 and is within the five-year phase-in period.

Employment Agreements

Richard N. Grant, Jr.

In connection with his appointment as our Chief Executive Officer and President, we have entered into a letter agreement with Mr. Grant, dated July 24, 2020, which provides that Mr. Grant’s employment will be on an at-will basis and that he will be entitled to an annual base salary (“Grant Base Salary”) of $375,000 per year, subject to periodic review by the Compensation Committee. During Mr. Grant’s employment, he is eligible to participate in the Company’s annual bonus award plan. For fiscal years 2021 and thereafter, Mr. Grant’s goals for his annual bonus award are set forth in the Company’s executive officer compensation plan for such fiscal year and his award thereunder.

Under the terms of the letter agreement, Mr. Grant is eligible to participate in the employee benefit plans and programs (excluding severance) generally available to the Company’s senior executives and consistent with such plans and programs of the Company, including but not limited to medical, life and disability insurance, retirement, vacation/paid time off, fringe benefit, perquisite, business expense reimbursement and travel plans or programs, in accordance with and subject to eligibility and other terms and conditions of such plans and programs, as in effect from time to time. As a condition of accepting his offer of employment, Mr. Grant also executed a Confidentiality, Non-Competition and Non-Solicitation Agreement, which includes standard restrictive covenants, assignment of inventions, confidentiality and non-disparagement, and non-competition and non-solicitation of employees, customers and suppliers provisions.

Duncan Gilmour

In connection with his appointment as our Chief Financial Officer, Treasurer and Secretary, we entered into a letter agreement with Mr. Gilmour, dated June 10, 2021, which provides that Mr. Gilmour’s employment will be on an at-will basis and that he will be entitled to an annual base salary (“Gilmour Base Salary”) of $240,000 per year, subject to periodic review by the Compensation Committee. During Mr. Gilmour’s employment, he is eligible to participate in the Company’s annual bonus award plan. For 2021, Mr. Gilmour was eligible to receive the 2021 Bonus, which was a pro-rated annual bonus based upon his initial Gilmour Base Salary for the last three quarters of 2021. Seventy percent of the 2021 Bonus was based on the Company’s achievement of its financial performance goals against its budget, with the potential for payment of up to 150% of target. Twenty percent of the 2021 Bonus was based upon completion of merger and acquisitions targets, with the potential for payment of up to 100% of target. The remaining 10% of the 2021 Bonus was based on risk management oversight, with the potential for payment of up to 100% of target. For fiscal years 2022 and thereafter, Mr. Gilmour’s actual bonus payment under the annual bonus award plan will be set forth in the Company’s executive officer compensation plan for such fiscal year and his award.

Under the terms of his offer letter, Mr. Gilmour also received an additional performance-based award (the “Performance Award”) of restricted common stock. The total number of shares of restricted common stock subject to the Performance Award is equal to (a) $100,000 (based on target performance) divided by (b) the closing price of the Company’s common stock on June 14, 2021. The Performance Award will vest on August 24, 2023 at a vesting percentage as determined in the sole discretion of the Committee under the performance goals described in a written restricted stock agreement. As a condition of his employment, Mr. Gilmour also executed a Confidentiality, Non-Competition and Non-Solicitation Agreement, which includes standard restrictive covenants, assignment of inventions, confidentiality and non-disparagement, and non-competition and non-solicitation of employees, customers and suppliers provisions.

Scott Nolen

We do not have an employment agreement with Mr. Nolen, who is employed on an “at will” basis.

Retirement Benefits

Our named executive officers are provided retirement benefits under the tax-qualified 401(k) plan provided to our other domestic employees. Our named executive officers are subject to provisions that allow participants to make contributions from their own salary on a pre-tax basis and provide a discretionary employer matching contribution not to exceed $4,750 a year. If eligible, the amount of employer contributions made to our 401(k) plans for our named executive officers for 2022 and 2021 are included in the column entitled “All Other Compensation” in the Summary Compensation Table above. We do not provide any other retirement benefits to our named executive officers.

Executive Compensation (continued)

Potential Payments upon Termination Following a Change of Control

We have Change of Control Agreements with Mr. Grant, our President and Chief Financial Officer, and Mr. Gilmour, our Chief Financial Officer, Treasurer, and Secretary (the “Change of Control Agreements”). The Change of Control Agreements provide for the payment of certain benefits upon the executive officer’s separation from service by us without Cause (as defined below) or by the executive officer for Good Reason (as defined below) within two years following a Change of Control. These benefits consist of the continuation of the executive officer’s base salary and continued coverage under group benefit plans for the one-year period following the separation of such executive officer’s service from the Company and payment of the variable performance based compensation that he would have earned for such one year period.

Under the Change of Control Agreements, a “Change of Control” occurs in the event of:

Under the Change of Control Agreements, a termination for “Cause” means the executive’s termination by us because of an act of fraud upon inTEST, a violation of inTEST’s Code of Ethics, willful refusal to perform the duties assigned to him by the Board or conviction for any crime involving dishonesty or breach of trust or for any crime that is a felony or of moral turpitude.

The term “Good Reason” under the Change of Control Agreements means a material adverse change in an executive’s status, responsibilities or benefits; a failure to be nominated or elected to his current officer position; a requirement to report to anyone other than his direct report; an assignment of duties inconsistent with his current officer position; any reduction in base salary, variable component or formula for determining the variable component which would have the effect of reducing his variable component, or other reduction in compensation or benefits; or a requirement to relocate more than thirty miles from his current office.

The benefits payable under the Change of Control Agreements are subject to the release of any claims that the named executive officers may have against us pursuant to the agreements as we may request. Benefits will be reduced or eliminated to the extent that comparable benefits are received from another source. Furthermore, the benefits will be reduced to the extent that the payments would not be deductible by us (in whole or in part) under Section 280G of the Internal Revenue Code.

In the event of a Change of Control, all equity awards issued to our executive officers become 100% vested.

DIRECTOR COMPENSATION

In 2022, non-employee directors received an annual retainer of $25,000, and the Chairperson of the Board received an additional annual retainer of $40,000. The Chairperson of each of the Committees of the Board were paid an additional annual fee as follows: the Chairperson of the Audit Committee received an additional annual fee of $20,000 and the Chairpersons of the Compensation Committee and Nominating and Corporate Governance Committee each received an additional annual fee of $10,000, respectively. The members of the Committees, other than the Chairpersons, receive additional annual fees of: $10,000 for members of the Audit Committee and $5,000 for members of each of the Compensation Committee and Nominating and Corporate Governance Committee, respectively. Also, in March 2022, based upon the evaluation and recommendation of Radford, the Compensation Committee recommended, and the Board approved, the award of 9,000 shares of restricted stock to each of the non-employee directors to further align their interests with those of our stockholders. Such shares vested 25% on each of the following dates: March 31, 2022, June 30, 2022, September 30, 2022 and December 31, 2022 subject to certain conditions, including, but not limited to, the continued service to inTEST of the respective non-employee director through each such vesting date.

In addition, the Company reimburses non-employee directors’ travel expenses and other costs associated with attending Board or committee meetings. The Company does not pay additional compensation to any executive officer for service as a director.

The following table sets forth the compensation earned by, or paid to, the members of our Board, who are not executive officers, for the year ended December 31, 2022:

PAY VERSUS PERFORMANCE

As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between executive compensation and our financial performance for each of the last two completed calendar years. In determining the “compensation actually paid” to our NEOs, we are required to make various adjustments to amounts that have been previously reported in the Summary Compensation Table in previous years, as the SEC’s valuation methods for this section differ from those required in the Summary Compensation Table.

Pay Versus Performance Table

The table below summarizes compensation values both previously reported in our Summary Compensation Table, as well as the adjusted values required in this section for fiscal years 2021 and 2022. Note that for our NEOs other than our principal executive officer (the “PEO”), compensation is reported as an average.

inTEST Corporation | 2023 Proxy Statement – 35

Pay Versus Performance (continued)

Relationship Between Compensation Actually Paid and Performance

The Company adheres to a pay-for-performance philosophy. We believe the compensation program we have designed incentivizes our executive team to drive results that create value for our shareholders. As such, equity incentive awards are a major component of the compensation paid to the PEO and the Non-PEO NEOs. Stock price is the primary driver of both the value of these awards and total shareholder return and year-ending compensation actually paid and total shareholder returns are significantly influenced by movement in the Company’s stock price. INTT stock moved from $6.49 as of December 31, 2020, to $12.72 as of December 31, 2021, to $10.30 as of December 31, 2022. As a result, from January 1, 2021 to December 31, 2021, total shareholder return increased by approximately 96% and from January 1, 2022 to December 31, 2022, total shareholder return decreased by approximately 19%. Note that this 2022 decrease resulted despite net income increasing approximately 16% in 2022 to $8.5 million when compared to 2021.

The compensation actually paid to the PEO for 2022 decreased 54% as compared to 2021 while the compensation actually paid to the non-PEO NEOs increased 9% for 2022 as compared to 2021. These changes compare with a 19% decrease in total shareholder return for the period from January 1, 2022 to December 31, 2022. As noted above, the changes in compensation actually paid from year to year are largely driven by stock-price movement. The decrease for the PEO reflects the decline in our stock price during 2022 and, more specifically, the change in value of accumulated equity positions held by the PEO as a result of these stock-price movements. The decrease in stock price also impacted the compensation actually paid to our non-PEO NEOs but this was more than offset by the fact that the 2021 compensation actually paid was reduced by forfeitures and timing of grants associated with the 2021 CFO transition – hence the lack of correlation with the significant stock-price appreciation during 2021.

PROPOSAL NO. 2: APPROVAL OF THE inTEST CORPORATION 2023 STOCK INCENTIVE PLAN

Overview

We are asking our stockholders to approve the adoption of the inTEST Corporation 2023 Stock Incentive Plan (the “2023 Plan”). Our Board approved and adopted the 2023 Plan on March 20, 2023, subject to stockholder approval. The 2023 Plan is now being submitted to our stockholders for their approval.

The 2023 Plan will become effective upon stockholder approval, and no awards may be granted under the 2023 Plan after the date that is 10 years from the date the 2023 Plan was last approved by our stockholders.

If approved, the 2023 Plan will replace the Company’s Fourth Amended and Restated 2014 Stock Plan (the “2014 Plan”), and no further awards would be granted under the 2014 Plan.

The closing stock price of a share of the Company’s common stock as reported on the NYSE American on April 24, 2023, our record date, was $20.39.

We currently grant equity awards under our 2014 Plan. As of April 24, 2023, of the 2,500,000 shares of our common stock reserved for issuance under the 2014 Plan, only 780,824 shares remained available for future grant. Approval of the 2023 Plan is intended to enable us to continue granting equity awards, which we believe is a key element of our compensation program. If this proposal is not approved by our stockholders, we will be limited in our ability to continue to grant equity awards to our directors, officers, employees and other service providers. As a result, we would lose an important compensation tool and would be forced to use cash replacement alternatives.

We believe the 2023 Plan reflects best practices for equity compensation, including the following:

Summary of the 2023 Plan

The full text of the 2023 Plan is attached to this proxy statement as Appendix A. The principal terms of the 2023 Plan are described below, but the description is qualified in its entirety by reference to the 2023 Plan itself. In the event of a conflict between the description and the terms of the 2023 Plan itself, the terms of the 2023 Plan will govern. The 2023 Plan will not become effective unless approved by our stockholders.

inTEST Corporation | 2023 Proxy Statement – 37

Proposal No. 2: Approval of the inTEST Corporation 2023 Stock Incentive Plan (continued)

Purpose

The purpose of the 2023 Plan is to promote stockholder value and the future success of the Company by providing appropriate retention and performance incentives to the employees and non-employee directors of the Company and its affiliates, and any other individuals who perform services for the Company or its affiliates.

Administration

Except as noted below, the 2023 Plan will be administered by the Compensation Committee of the Board (the “Committee”), provided such Committee consists of two or more individuals, and each member of the Committee will be required to be both a “Non-Employee Director” within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and a non-employee director meeting the independence requirements for compensation committee members under the rules and regulations of the NYSE American, or such other principal securities market on which the Company’s shares of common stock are traded.

Except as noted below, the Committee will have the authority to select the employees and other individuals to receive awards under the 2023 Plan, to determine the type, size and terms of the award to be made to each individual selected, to modify the terms of any award that has been granted, to determine the time when awards will be granted, to establish performance objectives, and to prescribe the form of award agreement. The Committee is also authorized to interpret the 2023 Plan and the awards granted under the 2023 Plan, to establish, amend and rescind any rules and regulations relating to the 2023 Plan, and to make any other determinations that it deems necessary or desirable for the administration of the 2023 Plan. The Board has all the powers otherwise vested in the Committee by the terms of the 2023 Plan in respect of awards granted to non-employee directors.

Notwithstanding the foregoing or any other provision of the 2023 Plan, except for permitted adjustments in connection with a corporate transaction or recapitalization, neither the Committee nor the Board may reprice, adjust or amend the exercise price of stock options or stock appreciation rights previously awarded, whether through amendment, cancellation and replacement grant, or any other means, unless such action is approved by the stockholders of the Company. The prohibition on repricing includes (a) the reduction, directly or indirectly, of the per-share exercise price of an outstanding stock option or stock appreciation right by amendment, cancellation or substitution; (b) any action that is treated as a repricing under U.S. generally accepted accounting principles; (c) the cancellation of a stock option or stock appreciation right in exchange for another stock option, stock appreciation right or other equity security (unless the cancellation and exchange occurs in connection with a merger, acquisition, or similar transaction); and (d) any other action that is treated as a repricing by the rules or regulations of the exchange on which the Company’s shares are traded. In addition, notwithstanding any other provision in the 2023 Plan, a stock option or stock appreciation right may not be surrendered in consideration of, or exchanged for cash, other awards, or a new stock option or stock appreciation right having an exercise price below that of the stock option or stock appreciation right which was surrendered or exchanged, unless the exchange occurs in connection with a merger, acquisition, or similar transaction, or such action is approved by the stockholders of the Company.

No director, no member of the Committee and no officer of the Company will be liable for anything done or omitted to be done by him or her, by any other director, by any other member of the Committee or by any officer of the Company in connection with the performance of duties under the 2023 Plan, except for his or her own willful misconduct or gross negligence, or as expressly provided by applicable law, and the Company will indemnify each director, member of the Committee and officer of the Company against any such liability.

Authorized Shares

The maximum number of shares of common stock available for grant and issuance under the 2023 Plan will be (a) 350,000, plus (b) the number of shares of common stock available for issuance under the 2014 Plan on the date the 2023 Plan is approved by stockholders, plus (c) any shares of common stock that are subject to awards granted under the Prior Plan that expire, are forfeited or canceled or terminate for any other reason on or after the date the 2023 Plan is approved by stockholders, without the issuance of shares. For the avoidance of doubt, any shares of common stock that are subject to outstanding awards granted under the 2014 Plan that are used to pay the exercise price of a stock option or withheld to satisfy the tax withholding obligations related to any award under the 2014 Plan on or after the date the 2023 Plan is approved by stockholders shall not become available under the 2023 Plan.

38 – inTEST Corporation | 2023 Proxy Statement

Proposal No. 2: Approval of the inTEST Corporation 2023 Stock Incentive Plan (continued)

Awards granted through the assumption of, or substitution for, outstanding awards previously granted by a company acquired by the Company or any affiliate, or with which the Company or any affiliate combines, will not reduce the maximum number of shares of common stock that may be issued under the 2023 Plan.

Awards will be counted against the available share reserve on the date of grant, based on the maximum number of shares that may be issued pursuant to the award. Any shares of common stock related to awards issued under the 2023 Plan that are forfeited, canceled, expired or otherwise terminated without the issuance of shares of common stock will again be available for issuance under the 2023 Plan. However, the following shares of common stock are not added back and may not be made available again under the 2023 Plan: (a) shares delivered to, or retained by the Company, in payment of the exercise price of a stock option; (b) shares delivered to, or retained by the Company, in satisfaction of the tax withholding obligations with respect to a stock option or stock appreciation right; (c) shares covered by a stock-settled stock appreciation right or other award that were not issued upon the settlement of the stock appreciation right or other award; and (d) shares repurchased on the open market with the proceeds from the payment of the exercise price of a stock option.

Eligible Participants

Employees and non-employee directors of the Company or its affiliates, and other individuals who perform services for the Company or its affiliates, are eligible to receive awards under the 2023 Plan. As of April 24, 2023, approximately 26 persons, including 5 executive officers, 4 non-employee directors and approximately 17 other individuals may be considered for awards under the 2023 Plan.

Neither the Compensation Committee nor the Board has made any decisions with respect to the individuals who may receive awards under the 2023 Plan on or after June 21, 2023 or the amount or nature of future awards.

Types of Awards

The 2023 Plan allows for the granting of the following types of awards: stock options (both incentive stock options and nonqualified stock options); stock appreciation rights; restricted stock; restricted stock units; and other stock-based awards. The Committee may also grant any other award providing similar benefits, subject to such terms, conditions and restrictions as it may determine necessary or appropriate to satisfy non-U.S. law or regulatory requirements or avoid adverse consequences under such requirements. Each award granted under the 2023 Plan is subject to an award agreement containing the particular terms and conditions of that award, subject to the limitations imposed by the 2023 Plan.

Stock Options. A stock option is the right to purchase a specified number of shares for a specified exercise price. Stock options may be either (a) incentive stock options, which are stock options that meet the requirements under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), or (b) nonqualified stock options, which are stock options that do not meet the requirements of Section 422 of the Code or that are designated as a nonqualified stock option. Awards of incentive stock options may only be made to employees, and incentive stock options are subject to additional limitations. Stock options (other than stock options assumed or granted in substitution for outstanding stock options of a company acquired by the Company or any affiliate) shall have an exercise price that is equal to or greater than the fair market value of the shares subject to such stock option on the date of grant. The expiration date of a stock option shall be no later than 10 years from the date of grant. The exercise price may be payable either (1) in cash, (2) if permitted by the Committee, by withholding shares that would otherwise be issued having a fair market value on the exercise date equal to the exercise price, (3) if permitted by the Committee, by tendering shares previously acquired that have been held for at least six months, (4) if permitted by the Committee, by delivery of irrevocable instructions to a broker to deliver promptly the proceeds from the sale of shares or (5) any combination of the foregoing.

Stock Appreciation Rights. A stock appreciation right is a right to receive cash or other property based on the increase in the value of a share over the per share exercise price. Stock appreciation rights (other than stock appreciation rights assumed or granted in substitution for outstanding stock appreciation rights of a company acquired by the Company or any affiliate) shall have an exercise price that is equal to or greater than the fair market value of the shares subject to such stock appreciation right on the date of grant. The expiration date of a stock appreciation right shall be no later than 10 years from the date of grant.

Proposal No. 2: Approval of the inTEST Corporation 2023 Stock Incentive Plan (continued)

Restricted Stock. Restricted stock is an award of shares that is subject to vesting conditions. Prior to the expiration of the vesting period, unless otherwise determined by the Committee, a participant who has received an award of restricted stock has the right to vote and to receive dividends on the underlying unvested shares, subject, however, to the restrictions and limitations imposed pursuant to the 2023 Plan and award agreement.

Restricted Stock Units. A restricted stock unit is an award that is valued by reference to shares, which may be paid to a participant upon vesting in shares, cash or other property.

Other Stock-Based Awards. An other stock-based award is an award denominated or payable in shares, other than a stock option, stock appreciation right, restricted stock or restricted stock unit. Other stock-based awards may be settled in cash, shares or other property.

Dividend Equivalents. Awards other than stock options and stock appreciation rights may include the right to receive dividends or dividend equivalents, subject to such terms, conditions, restrictions or limitations, if any, as the Committee may establish. Dividend equivalents will only be paid with respect to an award if, when and to the extent that the underlying award vests. Dividends and dividend equivalents will either be held in escrow or reinvested into additional shares of common stock subject to the same vesting or performance conditions as the underlying award.

Award Limitations

Minimum Vesting Period. All awards must be subject to a minimum vesting period of at least one year, except (a) that up to a maximum of five percent of the maximum number of shares of common stock that may be issued under the 2023 Plan may be issued pursuant to awards granted without regard for any minimum vesting period, (b) as the Committee may determine or permit otherwise in the event of the death or disability of the participant, or in connection with a change in control of the Company, subject to the discussion below under “Change in Control,” and (c) awards granted through the assumption of, or substitution for, outstanding awards of a company acquired by the Company or any affiliate.

Non-Employee Director Award Limitation. The sum of (a) the grant date fair value of the awards granted under the 2023 Plan in any calendar year to any non-employee director in respect of services as a non-employee director, and (b) the amount that may be paid in that calendar year to any non-employee director in property other than shares of common stock, including cash, in respect of services as a non-employee director, shall not exceed $500,000.

Incentive Stock Options. Incentive stock options may be granted subject to and shall be designed to comply with the provisions of Section 422 of the Code. To the extent that the aggregate fair market value (determined as of the date of grant) of the shares of common stock with respect to which incentive stock options are exercisable for the first time by any individual during any calendar year (under all plans of the Company and its affiliates) exceeds $100,000 (or such other limit that applies at the time of grant), such incentive stock options or portions thereof which exceed such limit (according to the order in which they were granted) will be treated as nonqualified stock options. If, at the time an incentive stock option is granted, the employee recipient owns (after application of the rules contained in Section 424(d) of the Code) shares of common stock possessing more than 10 percent of the total combined voting power of all classes of stock of the Company or its subsidiaries, then: (a) the exercise price for such incentive stock option will be at least 110 percent of the fair market value of the shares of common stock subject to such incentive stock option on the date of grant; and (b) such incentive stock option will not be exercisable after the date five years from the date such incentive stock option is granted. The maximum number of shares of common stock that may be issued under the 2023 Plan pursuant to incentive stock options may not exceed, in the aggregate, the maximum number of shares authorized for issuance under the 2023 Plan.

Tax Withholding

The exercise or payment of awards and the issuance of shares under the 2023 Plan is conditioned upon a participant making satisfactory arrangements for the satisfaction of any liability to withhold federal, state, local or foreign income or other taxes. In accordance with rules established by the Committee, the required tax withholding obligations may be settled in cash, or with shares, including shares that are part of the award that gives rise to the withholding requirement (up to the minimum required tax withholding rate or such other rate that will not trigger a negative accounting impact).

Proposal No. 2: Approval of the inTEST Corporation 2023 Stock Incentive Plan (continued)

Change in Control

The Committee may include in an award agreement provisions related to a “change in control” of the Company, provided that, any acceleration of the exercisability, vesting or settlement of, or the lapse of restrictions or deemed satisfaction of performance objectives with respect to, an award in connection with a change in control may occur only if both:

With respect to any award granted under the 2023 Plan that is earned or vested based upon achievement of performance objectives, any amount deemed earned or vested in connection with a change in control or associated termination of employment shall either be prorated or based upon the degree of performance attained through a date prior to the change in control determined by the Committee.

“Change in control” generally means the occurrence of any one or more of the following events:

No change in control will be deemed to have occurred by virtue of the consummation of any transaction or series of integrated transactions immediately following which the record holders of the capital stock of the Company immediately prior to such transaction or series of transactions continue to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately following such transaction or series of transactions.

Recoupment

Notwithstanding anything in the 2023 Plan or in any award agreement to the contrary, all awards granted under the 2023 Plan will be subject to recoupment in accordance with any clawback policy we adopt to the extent required by applicable law (including, without limitation, Section 10D of the Exchange Act and any regulations promulgated with respect thereto) or stock exchange listing conditions.

inTEST Corporation | 2023 Proxy Statement – 41

Proposal No. 2: Approval of the inTEST Corporation 2023 Stock Incentive Plan (continued)

Adjustments

In the event of any change in our outstanding shares of common stock by reason of any corporate transaction or change in corporate capitalization such as a stock split, reverse stock split, stock dividend, split-up, split-off, spin-off, recapitalization, merger, consolidation, rights offering, reorganization, combination, consolidation, subdivision or exchange of shares, a sale by the Company of all or part of its assets, any distribution to stockholders other than a normal cash dividend, partial or complete liquidation of the Company or similar event, the Committee or Board, as applicable, shall adjust (a) the class and maximum number of shares available under the 2023 Plan; (b) the class, number and exercise price of outstanding stock options and stock appreciation rights granted under the 2023 Plan; and (c) the class and number of shares subject to any other awards granted under the 2023 Plan, as may be determined to be appropriate by the Committee or Board, as applicable.

Amendment of Plan or Awards

The 2023 Plan may be amended in whole or in part at any time and from time to time by the Board, and the terms of any outstanding award under the 2023 Plan may be amended from time to time by the Committee or Board, as applicable, in its discretion provided that no amendment may be made without stockholder approval if such amendment would (a) increase the number of shares available for grant under the 2023 Plan; (b) decrease the minimum stock option or stock appreciation right exercise price; (c) reduce the minimum vesting or performance periods; (d) change the limits applicable to incentive stock options; (e) amend or repeal the prohibition against repricing or exchange; or (f) require stockholder approval under applicable law, including securities exchange listing conditions. No amendment may adversely affect in a material manner any right of a participant under an award without his or her written consent.

Termination

The 2023 Plan may be suspended in whole or in part at any time and from time to time by the Board. The 2023 Plan will terminate upon the adoption of a resolution of the Board terminating the 2023 Plan. No award may be granted under the 2023 Plan after the date that is 10 years from the date the 2023 Plan was last approved and adopted by the stockholders of the Company. No termination of the 2023 Plan will materially alter or impair any of the rights or obligations of any person, without his or her consent, under any award granted under the 2023 Plan, except that subsequent to termination of the 2023 Plan, the Committee may make any permitted amendments.

Certain U.S. Federal Income Tax Consequences of 2023 Plan Awards

The following discussion is intended to provide only a general outline of the U.S. federal income tax consequences of participation in the 2023 Plan and the receipt of awards or payments thereunder by participants subject to U.S. taxes. It does not address any other taxes imposed by the United States, taxes imposed by any state or political subdivision thereof or foreign jurisdiction, or the tax consequences applicable to participants who are not subject to U.S. taxes. The discussion set forth below does not purport to be a complete analysis of all potential tax consequences relevant to recipients of awards, particular circumstances, or all awards available under the 2023 Plan. It is based on U.S. federal income tax law and interpretational authorities as of the date of this proxy statement, which are subject to change at any time.

Nonqualified Stock Options

A participant who exercises a nonqualified stock option recognizes taxable ordinary income in the year the stock option is exercised in an amount equal to the excess of the fair market value of the shares purchased on the exercise date over the exercise price. Subject to applicable provisions of the Code, including Section 162(m), the Company is entitled to a tax deduction in an amount equal to the ordinary income recognized by the participant. Any gain or loss realized by the participant upon the subsequent disposition of the shares will be taxed as short-term (if held one year or less) or long-term (if held more than one year) capital gain, but will not result in any further deduction for the Company.

Incentive Stock Options

A participant who exercises an incentive stock option does not recognize ordinary income at the time of exercise (although, the participant may be subject to alternative minimum tax), and the Company is not entitled to a tax deduction.

42 – inTEST Corporation | 2023 Proxy Statement

Proposal No. 2: Approval of the inTEST Corporation 2023 Stock Incentive Plan (continued)

Upon the disposition of the shares obtained from the exercise of the incentive stock option more than two years after the date of grant and more than one year after the date of exercise, the excess of the sale price of the shares over the exercise price of the incentive stock option is taxed as long-term capital gain. If the shares are sold within two years of the grant date and/or within one year of the date of exercise, the excess of the fair market value of the shares on the date of exercise (or sale proceeds if less) over the exercise price is taxed as ordinary income, and, subject to applicable provisions of the Code, including Section 162(m), the Company is entitled to a tax deduction for this amount; any remaining gain is taxed as capital gain, without a Company tax deduction.

Stock Appreciation Rights

A participant who exercises a stock appreciation right recognizes taxable ordinary income in the year the stock appreciation right is exercised in an amount equal to the cash and/or the fair market value of any shares or other property received. Subject to applicable provisions of the Code, including Section 162(m), the Company is entitled to a tax deduction in an amount equal to the ordinary income recognized by the participant.

Restricted Stock, Restricted Stock Units and Other Stock-Based Awards

A participant normally will not recognize taxable income and the Company will not be entitled to a deduction upon the grant of shares of restricted stock, restricted stock units or other stock-based awards. When the restricted stock vests, the restricted stock units settle or the other stock-based awards are paid or settle, the participant will recognize taxable ordinary income in an amount equal to the fair market value of the shares or other property received at that time, less the amount, if any, paid for the shares, and, subject to applicable provisions of the Code, including Section 162(m), the Company will be entitled at that time to a deduction in the same amount. However, a participant may elect to recognize taxable ordinary income in the year shares of restricted stock are granted in an amount equal to the excess of their fair market value at the grant date, determined without regard to certain restrictions, over the amount, if any, paid for the shares. In that event, subject to applicable provisions of the Code, including Section 162(m), the Company will be entitled to a deduction in such year in the same amount. Any gain or loss realized by the participant upon the subsequent disposition of shares received will be taxed as short-term or long-term capital gain, but will not result in any further deduction for the Company.

New Plan Benefits

As of the date of this Proxy Statement, no awards have been made under the 2023 Plan that are contingent upon stockholder approval of this proposal. Because awards under the 2023 Plan are discretionary, the benefits or amounts to be received by or allocated to participants and the number of shares to be granted under the 2023 Plan cannot be determined at this time.

Vote Required

The affirmative vote of a majority of the total shares of our common stock that vote on this proposal is required for approval of the 2023 Plan.

Recommendation of the Board of Directors

The Board recommends a vote “FOR” the approval of the inTEST Corporation 2023 Stock Incentive Plan.

PROPOSAL 3: RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

RSM US LLP was appointed as our independent registered public accounting firm (“IRPA Firm”) on June 16, 2008. RSM US LLP audited our consolidated financial statements for the years ended December 31, 2022 and 2021. The Audit Committee of our Board has appointed RSM US LLP as our IRPA Firm for the year ending December 31, 2023, subject to the determination of the 2023 audit fees. The Audit Committee has the sole authority and responsibility to select, appoint, evaluate and, where appropriate, discharge and replace RSM US LLP as our IRPA Firm, and the appointment of our IRPA Firm is not required to be submitted to a vote of the stockholders for ratification. The Audit Committee has elected to submit its appointment of RSM US LLP for ratification by stockholders. Notwithstanding the outcome of the vote by the stockholders, the Audit Committee is not bound to retain the IRPA Firm or to replace the IRPA Firm, where, in either case, after considering the outcome of the vote, the Audit Committee determines its decision regarding the IRPA Firm to be in the best interests of inTEST. Representatives of RSM US LLP will attend the Annual Meeting and will be available to respond to questions and, if they desire, make a statement.

The following table sets forth the fees billed by RSM US LLP as described below:

Audit Fees: Consists of fees billed for professional services rendered in connection with the audit of our consolidated financial statements and review of the interim condensed consolidated financial statements for 2022 and 2021, respectively, that are included in quarterly reports during those years and services that are normally provided by our IRPA Firm in connection with statutory and regulatory filings or engagements, and attest services, except those not required by statute or regulation.

Audit-Related Fees: Consists of fees billed in each of 2022 and 2021 for assurance and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under “Audit Fees.” These services would include auditing procedures in connection with acquisitions and divestitures, attest services that are not required by statute or regulation, and auditing procedures in connection with the adoption of financial accounting and reporting standards.

Tax Fees: Consists of fees billed in each of 2022 and 2021 for tax related services including advice, preparation of returns and other tax services related to federal, state and international taxes.

All Other Fees: Consists of fees billed in each of 2022 and 2021 for all products and services provided by the principal accountant, other than those reported above. For 2022, the fees related to the audit and tax services for the foreign subsidiaries. For 2021, $306,000 was related to tax due diligence, tax planning and structure related to acquisitions completed in the year.

In accordance with the Sarbanes-Oxley Act of 2002, the Audit Committee’s policy is to pre-approve all audit and non-audit services provided by our IRPA Firm. On an ongoing basis, management defines and communicates specific projects and categories of service for which the advance approval of the Audit Committee is requested. The Audit Committee reviews these requests and advises management if the Audit Committee approves the engagement of our IRPA Firm for such services. The Audit Committee has also delegated authority to the Chairperson of the Audit Committee, and if the Chairperson of the Committee is unavailable, to any other Audit Committee member, to pre-approve permitted services. Any such pre-approval must be reported to the Audit Committee at its next meeting. For 2022 and 2021 approximately $14,000 and $8,000, respectively, of the fees for the services described in the table as Tax Fees were approved by the Audit Committee as de minimis as contemplated by Rule 2-01(c)(7)(i)(C) of Regulation S-X.

Recommendation of the Board

The Board recommends a vote “FOR” the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for the year ending December 31, 2023.

PROPOSAL 4: ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we are again providing our stockholders with the opportunity at the Annual Meeting to approve, on a non-binding advisory basis, the 2022 compensation of our named executive officers as disclosed in the Executive Compensation section of this proxy statement, including the Overview of the Executive Compensation Program, the Summary Compensation Table and the related tables, notes, and narratives. Currently this “say on pay” vote is conducted every year. As previously reported, the option of holding the advisory vote on the compensation of the Company’s named executive officers every year was approved on an advisory basis by a vote of the stockholders at the 2020 Annual Meeting of Stockholders. The Company’s Board considered the outcome of such advisory vote and determined to hold future stockholder advisory votes on executive compensation every year, until the Board determines that a different frequency for such votes is in the best interests of the Company’s stockholders or until the next required vote of the Company’s stockholders on the frequency of such votes.

We urge stockholders to read the discussion in this proxy statement of Executive Compensation which describes our 2022 executive compensation program principles and practices in more detail, including the Summary Compensation table and other related tables, notes and narratives, which provide detailed information about the compensation of our named executive officers.

While this proposal is an advisory vote that will be non-binding, the Board and the Compensation Committee will review and consider the voting results when making future decisions regarding the compensation of our named executive officers.

The next advisory vote on the compensation of our named executive officers will take place at our Annual Meeting of Stockholders to be held in 2024.

Recommendation of the Board

The Board recommends that you vote “FOR” the approval, on an advisory basis, of the compensation of our named executive officers.

INFORMATION REGARDING DEADLINES AND PROCEDURES FOR SUBMISSION OF STOCKHOLDER PROPOSALS AND NOMINATION OF DIRECTORS

Under the proxy rules of the SEC, stockholders intending to submit proposals to be included in our proxy statement for our Annual Meeting of Stockholders to be held in 2024 must send their proposals to Duncan Gilmour, Secretary at 804 East Gate Drive, Suite 200, Mt. Laurel, New Jersey 08054, not later than December 29, 2023. These proposals must relate to matters appropriate for stockholder action and be consistent with regulations of the SEC relating to stockholder proposals (“Rule 14a-8”) in order to be considered for inclusion in our proxy statement relating to that meeting.

Under our Bylaws, certain procedures are provided that a stockholder must follow to nominate persons for election as directors or to introduce an item of business at an annual meeting of stockholders. These procedures provide that nominations for director nominees and/or an item of business to be introduced at an annual meeting of stockholders must be submitted in writing to the Secretary of inTEST at the address set forth above, not later than 90 days and not earlier than 120 days prior to the first anniversary of the preceding year’s annual meeting of stockholders, subject to certain exceptions. Accordingly, a notice of a stockholder proposal, submitted outside of Rule 14a-8 under the Exchange Act, or a stockholder nomination for the 2024 Annual Meeting of Stockholders will be untimely if received by inTEST’s Secretary before February 22, 2024 or after March 23, 2024, unless the date of the 2024 Annual Meeting of Stockholders is advanced by more than 30 days or delayed (other than as a result of adjournment) by more than 30 days from the anniversary of the 2023 Annual Meeting. If the date of the 2024 Annual Meeting of Stockholders is changed by more than 30 days from the anniversary of the 2023 Annual Meeting, then notice by the stockholder to be timely must be delivered not earlier than the 120th day prior to the date of the 2024 Annual Meeting of Stockholders and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made.

To comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than nominees for our Annual Meeting of Stockholders to be held in 2024 must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 22, 2024.

Our Bylaws set forth various qualifications and disclosure requirements for such advance written notice of a nomination or proposal to be in proper form. A stockholder wishing to submit such a notice should review the provisions of our Bylaws (which are filed with our Annual Report on Form 10-K for the year ended December 31, 2022). In general, the disclosure requirements include information about the stockholder making the nomination or proposal, information regarding the nominee or proposal, and in the case of a nomination, a certification and consent from the nominee. If a stockholder fails to comply with the time of notice procedures set forth in our Bylaws, that stockholder will not be entitled to present the proposal or nomination at the meeting. If, however, notwithstanding the requirements of our Bylaws, a proposal is brought before the meeting, then under the SEC’s proxy rules, the proxies inTEST solicits with respect to the 2024 Annual Meeting of Stockholders will confer discretionary voting authority on the persons so named as proxies with respect to such proposal.

ANNUAL REPORT

Our Annual Report to Stockholders (which includes our consolidated financial statements for the year ended December 31, 2022), accompanies this proxy statement. The Annual Report to Stockholders does not constitute a part of the proxy solicitation materials.

For the avoidance of doubt, any shares of Common Stock that are subject to outstanding awards granted under the Prior Plan that are used to pay the exercise price of an option or withheld to satisfy the tax withholding obligations related to any award under the Prior Plan on or after the Effective Date, shall not become available under the Plan.

(c)    Share Counting. For purposes of counting shares against the maximum number of shares of Common Stock that may be issued under the Plan as described in Section 5.1(a), on the date of grant, Awards denominated solely in shares of Common Stock (such as Stock Options and Restricted Stock) and other Awards that may be exercised for, settled in or convertible into shares of Common Stock will be counted against the Plan reserve on the date of grant of the Award based on the maximum number of shares that may be issued pursuant to the Award, as determined by the Committee.

(d)    Shares Added Back. Shares of Common Stock related to Awards issued under the Plan that are forfeited, canceled, expired or otherwise terminated without the issuance of shares of Common Stock will again be available for issuance under the Plan.

No Award may be granted under the Plan after the date that is 10 years from the date the Plan was last approved and adopted by the stockholders of the Company. No termination of the Plan shall materially alter or impair any of the rights or obligations of any person, without his or her consent, under any Award theretofore granted under the Plan, except that subsequent to termination of the Plan, the Committee may make amendments permitted under Section 12.

Section 14.     Miscellaneous

14.1     Loans. No loans from the Company or any Affiliate to a Participant shall be permitted in connection with the Plan.

14.2     Reservation of Rights of Company. No employee or other person shall have any claim or right to be granted an Award under the Plan. Neither the Plan nor any action taken hereunder shall be construed as giving any employee or other person any right to continue to be employed by or perform services for the Company or any Affiliate, and the right to terminate the employment of or performance of services by any Participant at any time and for any reason is specifically reserved.

14.3     Non-Uniform Treatment. Determinations made by the Committee under the Plan need not be uniform and may be made selectively among eligible individuals under the Plan, whether or not such eligible individuals are similarly situated.

Appendix A

14.4     General Conditions of Awards. No Participant or other person shall have any right with respect to the Plan, the shares of Common Stock reserved for issuance under the Plan or in any Award, contingent or otherwise, until written evidence of the Award shall have been delivered to the recipient and all the terms, conditions and provisions of the Plan and the Award applicable to such recipient (and each person claiming under or through him or her) have been met.

14.5     Rights as a Stockholder. Unless otherwise determined by the Committee in its discretion, a Participant holding Stock Options, Stock Appreciation Rights, Restricted Stock Units, Other Stock-Based Awards or other Awards shall have no rights as a stockholder with respect to any shares of Common Stock (or as a holder with respect to other securities), if any, issuable pursuant to any such Award until the date of the issuance of a stock certificate to him or her or the entry on his or her behalf of an uncertificated book position on the records of the Company’s transfer agent and registrar for such shares of Common Stock or other instrument of ownership, if any. Except as provided in Section 11, no adjustment shall be made for dividends, distributions or other rights (whether ordinary or extraordinary, and whether in cash, securities, other property or other forms of consideration, or any combination thereof) for which the record date is prior to the date such book entry is made or a stock certificate or other instrument of ownership, if any, is issued.

14.6     Compliance with Applicable Laws. No shares of Common Stock or other property shall be issued or paid hereunder with respect to any Award unless counsel for the Company shall be satisfied that such issuance will be in compliance with applicable federal, state, local and foreign legal, securities exchange and other applicable requirements. The Company shall be under no obligation to effect the registration pursuant to the Securities Act of 1933, as amended, of any shares of Common Stock to be issued hereunder or to effect similar compliance under any state or local laws.

14.7     Withholding of Taxes. The Company and its Affiliates shall have the right to deduct from any payment made under the Plan the federal, state, local or foreign income or other taxes required by law to be withheld with respect to such payment. In accordance with rules and procedures established by the Committee, the required withholding obligations may be settled with shares of Common Stock, including shares of Common Stock that are part of the Award that gives rise to the withholding requirement (up to the Participant’s minimum required tax withholding rate or such other rate that will not trigger a negative accounting impact). It shall be a condition to the obligation of the Company to issue shares of Common Stock or other property, or any combination thereof, upon exercise, settlement or payment of any Award under the Plan, that the Participant pay to the Company, upon its demand, such amount as may be requested by the Company for the purpose of satisfying any liability to withhold federal, state, local or foreign income or other taxes. If the amount requested is not paid, the Company may refuse to issue or pay shares of Common Stock or other property, or any combination thereof. Notwithstanding anything in the Plan to the contrary, the Committee may, in its discretion, permit an eligible Participant to elect to pay a portion or all of the amount requested by the Company for such taxes with respect to such Award, at such time and in such manner as the Committee shall deem to be appropriate (including, but not limited to, by authorizing the Company to withhold, or agreeing to surrender to the Company on or about the date such tax liability is determinable, shares of Common Stock or other property, or any combination thereof that would otherwise be distributed, or have been distributed, as the case may be, pursuant to such Award to such person, having a fair market value equal to the amount of such taxes).

14.8     Unfunded Nature of Plan. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Award under the Plan, and the rights to the payment of Awards shall be no greater than the rights of the Company’s general creditors.

14.9     Consent. By accepting any Award or other benefit under the Plan, each Participant and each person claiming under or through him or her shall be conclusively deemed to have indicated his or her acceptance and ratification of, and consent to, any action taken under the Plan by the Company, the Board or the Committee.

14.10     No Warranty of Tax Effect. Although the Company may structure an Award to qualify for favorable federal, state, local or foreign tax treatment, or to avoid adverse tax treatment, no person connected with the Plan in any capacity, including, but not limited to, the Company and its directors, officers, agents and employees, makes any representation, commitment or guarantee that any intended tax treatment will be applicable with respect to any Award under the Plan, or that such tax treatment will apply to or be available to a Participant or his or her beneficiary. Furthermore, the existence of an Award shall not affect the right or power of the Company or its stockholders to take any corporate action, regardless of the potential effect of such action on the tax treatment of an Award under the Plan.

14.11     Interpretation. Unless the context indicates otherwise, references to “Sections” in the Plan refer to Sections of the Plan. Headings of Sections herein are inserted only for convenience of reference and are not to be considered in

Appendix A

the construction of the Plan. In the Plan, the use of the masculine pronoun shall include the feminine and the use of the singular shall include the plural, as appropriate.

14.12     Severability. If any provision of the Plan shall be held unlawful or otherwise invalid or unenforceable in whole or in part by a court of competent jurisdiction, such provision shall: (a) be deemed limited to the extent that such court of competent jurisdiction deems it lawful, valid or enforceable and as so limited shall remain in full force and effect; and (b) not affect any other provision of the Plan or part thereof, each of which shall remain in full force and effect.

14.13     Choice of Law. The validity, construction, interpretation, administration and effect of the Plan, and of its rules and regulations, and rights relating to the Plan and to Awards granted under the Plan, shall be governed by the substantive laws, but not the choice of law rules, of the State of Delaware.

14.14     Section 409A. Awards granted under the Plan are intended to qualify for an exception from or comply with Section 409A, and the Plan and Award Agreements shall be administered, construed and interpreted in accordance with such intent. To the extent that an Award or the payment, settlement or deferral thereof is subject to Section 409A, the Award shall be granted, paid, settled or deferred in a manner that will comply with Section 409A and any Section 409A compliance policy of the Company and in no event will the Company be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by a Participant on account of non-compliance with Section 409A. To the extent any payment of an Award may be classified as a “short-term deferral” within the meaning of Section 409A, such payment will be deemed a short-term deferral, even if it may also qualify for an exemption from Section 409A under another provision of Section 409A. Notwithstanding anything in the Plan or any Award Agreement to the contrary, if a Participant is a “specified employee” (within the meaning of Section 409A(2)(B)) as of the date of such Participant’s separation from service (as determined pursuant to Section 409A), then to the extent any Award payable to such Participant on account of such separation from service would be considered nonqualified deferred compensation under Section 409A, such payment or benefit shall be paid or provided in a lump sum upon the earlier of six months and one day after such separation from service, and the date of the Participant’s death. Unless the Committee determines otherwise, any provision of the Plan that would cause the grant of an Award or the payment, settlement or deferral thereof to fail exemption from or compliance with Section 409A may be amended to qualify for exemption from or comply with Section 409A, which may be made on a retroactive basis, in accordance with Section 409A.
