The Notice of Meeting and Proxy Statement on the following pages describe the matters to be presented at the Annual Meeting and provide details regarding how to attend the meeting.

We are providing access to our proxy materials over the Internet under the United States Securities and Exchange Commission’s “notice and access” rules. As a result, we are mailing to many of our stockholders a notice instead of a paper copy of this Proxy Statement and our 2021 Annual Report to Stockholders. The notice contains instructions on how to access those documents over the Internet. The notice also contains instructions on how you can receive a paper copy of our proxy materials, including this Proxy Statement, our 2021 Annual Report to Stockholders, and a form of proxy card or voting instruction card. All stockholders who do not receive a notice, including stockholders who have previously requested to receive paper copies of proxy materials, will receive a paper copy of the proxy materials by mail unless they previously have requested delivery of proxy materials electronically.

Whether or not you attend the Annual Meeting, it is important that your shares be represented and voted at the Annual Meeting. Therefore, I urge you to promptly vote and submit your proxy by phone, via the Internet, or, if you received paper copies of these materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope, which requires no postage if mailed in the United States. If you have previously received our Notice of Internet Availability of Proxy Materials in the mail or by email, then instructions regarding how you can vote are contained in that notice. If you have received a proxy card, then instructions regarding how you can vote are contained on the proxy card. If you decide to attend the Annual Meeting, you will be able to vote in person at the Annual Meeting, even if you have previously submitted your proxy, as your proxy is revocable at your option.

Thank you for your support and continued interest in NCS Multistage Holdings, Inc.

Sincerely,

Robert Nipper

Chief Executive Officer

INFORMATION ABOUT THIS PROXY STATEMENT

Why You Received This Proxy Statement. You are viewing or have received these proxy materials because the Company’s Board of Directors is soliciting your proxy to vote your shares at the Annual Meeting, which will be held at 19350 State Highway 249, Suite 600, Houston, Texas 77070 on June 1, 2022. As a stockholder, you are invited to participate in the Annual Meeting and to vote on the business items described in this Proxy Statement. This Proxy Statement includes information that we are required to provide to you under the rules of the United States Securities and Exchange Commission (the “SEC”) and is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, we are making this Proxy Statement and our 2021 Annual Report available to our stockholders electronically via the Internet. On or about April 11, 2022, we sent by mail or email to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this Proxy Statement and our 2021 Annual Report and to vote online. If you received an Internet Notice, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you how to access and review all of the information contained in the Proxy Statement and the 2021 Annual Report. The Internet Notice also instructs on how you may submit your proxy over the Internet. If you received an Internet Notice and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained in the Internet Notice. In addition, the Internet Notice contains instructions on how you may request proxy materials in printed form by mail or electronically on an ongoing basis.

Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials.

Householding. The SEC’s rules permit us to deliver a single Internet Notice or set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one Internet Notice or one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the Internet Notice or proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. Alternatively, stockholders sharing an address who are receiving multiple copies of the proxy materials or Internet Notice, as applicable, may request to receive a single copy of such materials in the future. Instructions for making these requests are provided below under “Questions and Answers about the 2022 Annual Meeting of Stockholders.”

QUESTIONS AND ANSWERS ABOUT THE 2022 ANNUAL MEETING OF STOCKHOLDERS

Who Is Entitled to Vote at the Annual Meeting?

Each holder of shares of Common Stock issued and outstanding as of the close of business on April 5, 2022 (the Record Date for the Annual Meeting) is entitled to cast one vote per share on items being voted on at the Annual Meeting. You may vote all shares owned by you as of that time, including (a) shares held directly in your name as the stockholder of record and (b) shares held for you as the beneficial owner through a broker, trustee or other nominee. At the close of business on the Record Date, there were 2,406,093 shares of Common Stock issued and outstanding and entitled to vote at the Annual Meeting.

What Is the Difference Between Being a “Record Holder” and Holding Shares in “Street Name” as a Beneficial Owner?

A record holder holds shares in his or her own name. Shares held in “street name” means shares that are held in the name of a broker, trustee or other nominee on a person’s behalf. If your shares are held in “street name” you are considered the “beneficial owner” of those shares. As the beneficial owner, you have the right to direct your broker, trustee or other nominee how to vote. You may also vote your shares during the Annual Meeting. Most of our stockholders are beneficial owners who hold their shares in street name rather than directly in their own name.

Am I Entitled to Vote If My Shares Are Held in “Street Name”?

Yes. If you are a beneficial owner whose shares are held in street name you have the right to direct your broker, trustee or other nominee how to vote your shares, and the nominee is required to vote your shares in accordance with your instructions. You may also vote your shares during the Annual Meeting by attending the Annual Meeting and voting your shares at that time.

How May I Obtain a Paper Copy of the Proxy Materials?

Stockholders receiving an Internet Notice will find instructions about how to obtain a paper copy of the proxy materials on their Internet Notice. Stockholders receiving an Internet Notice by email will find instructions about how to obtain a paper copy of the proxy materials as part of that email. All stockholders who do not receive an Internet Notice or an email will receive a paper copy of the proxy materials by mail.

I Share an Address with Another Stockholder, and We Received Only One Paper Copy of the Proxy Materials or Internet Notice. How May I Obtain an Additional Copy?

If you share an address with another stockholder, you may receive only one paper copy of the proxy materials or Internet Notice, as applicable, unless you have provided contrary instructions. If you are a beneficial owner and wish to receive a separate set of proxy materials or Internet Notice, please request the additional copy by contacting your individual broker, trustee or other nominee. If you are a stockholder of record and wish to receive a separate set of the proxy materials or Internet Notice, please contact Broadridge Financial Solutions, Inc. (“Broadridge”) at the following address: Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York, 11717 or call Broadridge at 1-866-540-7095.

In addition, all stockholders also may write to us at the address below to request a separate set of proxy materials or Internet Notice, as applicable:

I Share an Address with Another Stockholder, and We Received More Than One Paper Copy of the Proxy Materials or Internet Notice. How Do We Obtain a Single Copy in the Future?

Beneficial owners of shares held through a broker, trustee or other nominee sharing an address who are receiving multiple copies of the proxy materials or Internet Notice, as applicable, and who wish to receive a single copy of such materials in the future may contact your individual broker, trustee or other nominee. Stockholders of record sharing an address who are receiving multiple copies of the proxy materials or Internet Notice, as applicable, and who wish to receive a single copy of such materials in the future may contact Broadridge at the following address: Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York, 11717 or call Broadridge at 1-866-540-7095.

How Can I Attend the Annual Meeting?

You are entitled to participate in the Annual Meeting only if you were a NCS Multistage Holdings, Inc. stockholder or joint holder as of the close of business on April 5, 2022, or if you hold a valid proxy for the Annual Meeting.

You may be asked to present valid picture identification, such as a driver’s license or passport, before being admitted to the Annual Meeting. If you hold your shares in street name, you may also need proof of ownership to be admitted to the Annual Meeting. A recent brokerage statement or letter from your broker or other nominee are examples of proof of ownership.

How Many Shares Must Be Present to Hold the Annual Meeting?

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, in person or by proxy, of the holders of a majority in voting power of the shares entitled to vote on the Record Date will constitute a quorum.

What If a Quorum Is Not Present at the Annual Meeting?

If a quorum is not present at the scheduled time of the Annual Meeting, the chairperson of the Annual Meeting may adjourn the Annual Meeting.

4

How Do I Vote?

Even if you plan to participate in the Annual Meeting, we recommend that you vote by proxy as described below so that your vote will be counted if you later decide not to participate in the Annual Meeting. There are three ways to vote by proxy:

		VIA THE INTERNET   Stockholders who have received an Internet Notice by mail may submit proxies over the Internet by following the instructions on the Internet Notice. Stockholders who have received an Internet Notice by email may submit proxies over the Internet by following the instructions included in the email. Stockholders who have received a paper copy of a proxy card or voting instruction card by mail may submit proxies over the Internet by following the instructions on the proxy card or voting instruction card.
		BY TELEPHONE   Stockholders of record who live in the United States or Canada may submit proxies by telephone by calling 1-800-690-6903 and following the instructions. Stockholders of record who have received an Internet Notice by mail must have the control number that appears on their Internet Notice available when voting. Stockholders of record who received an Internet Notice by email must have the control number included in the email available when voting. Stockholders of record who have received a proxy card by mail must have the control number that appears on their proxy card available when voting. Most stockholders who are beneficial owners of their shares living in the United States or Canada and who have received a voting instruction card by mail may vote by phone by calling the number specified on the voting instruction card provided by their broker, trustee or other nominee. Those stockholders should check the voting instruction card for telephone voting availability.
		BY MAIL   Stockholders who have received a paper copy of a proxy card or voting instruction card by mail may submit proxies by completing, signing and dating their proxy card or voting instruction card and mailing it in the accompanying pre-addressed envelope.

Internet and telephone voting facilities will be available 24 hours a day and will close at 11:59 p.m., Eastern Time, or 10:59 p.m., Central Time, on May 31, 2022.

You can also vote at the Annual Meeting. You will need the 16-digit control number included on your proxy card or on the instructions that accompanied your proxy materials.

Can I Change My Vote After I Submit My Proxy?

Yes. If you are the stockholder of record, you may change your vote by: (1) submitting a new proxy bearing a later date (which automatically revokes the earlier proxy); (2) providing a written notice of revocation to the Secretary at our offices at NCS Multistage Holdings, Inc., 19350 State Highway 249, Suite 600, Houston, Texas 77070, prior to your shares being voted; or (3) participating in the Annual Meeting and voting your shares during the Annual Meeting. Participation in the Annual Meeting will not cause your previously submitted proxy to be revoked unless you specifically make that request.

For shares you hold beneficially in the name of a broker, trustee or other nominee, you may change your vote by submitting new voting instructions to your broker, trustee or nominee, or by participating in the Annual Meeting and voting your shares during the Annual Meeting.

5

What Is the Deadline for Voting My Shares?

If you hold shares as the stockholder of record, your vote by proxy must be received before the polls close during the Annual Meeting.

If you are the beneficial owner of shares held through a broker, trustee or other nominee, please follow the voting instructions provided by your broker, trustee or nominee.

What Does It Mean If I Receive More Than One Internet Notice or More Than One Set of Proxy Materials?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the proxy card in the enclosed envelope.

Who Will Count the Votes?

The person appointed as inspector of election will tabulate and certify the votes.

Is My Vote Confidential?

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed, either within the Company or to third parties, except: (1) as necessary to meet applicable legal requirements; (2) to allow for the tabulation of votes and certification of the votes; and (3) to facilitate a successful proxy solicitation. Occasionally, stockholders provide written comments on their proxy card, which may be forwarded to management for review.

What If I Do Not Specify How My Shares Are to Be Voted?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board of Directors.

Will Any Other Business Be Conducted at the Annual Meeting?

We know of no other business that will be presented at the Annual Meeting. However, if any other matter properly comes before the stockholders for a vote at the Annual Meeting, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

How Many Votes Are Required for the Approval of the Proposals to Be Voted upon and How Will Abstentions and Broker Non-Votes Be Treated?

6

What Is an Abstention and How Will Votes Withheld and Abstentions Be Treated?

A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of ratification of the appointment of Grant Thornton LLP (“GT”) as our independent registered public accounting firm, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. However, votes withheld and abstentions will otherwise have no effect on the proposals.

What Are Broker Non-Votes and Do They Count for Determining a Quorum?

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of GT as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors. Broker non-votes count for purposes of determining whether a quorum is present. However, on the proposals regarding the election of directors, broker non-votes will have no effect on the proposal.

Where Can I Find the Voting Results of the Annual Meeting?

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we will file with the SEC shortly after the Annual Meeting.

PROPOSAL 1: ELECTION OF DIRECTORS

At the Annual Meeting, three Class II directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2025 and until such director’s successor is elected and qualified or until such director’s earlier death, resignation or removal. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

Our Board is divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting of stockholders following election or such director’s death, resignation or removal, whichever is earliest to occur. The current class structure is as follows: Class II, whose term will expire at the Annual Meeting; Class III, whose term will expire at the 2023 Annual Meeting of Stockholders; and Class I, whose term will expire at the 2024 Annual Meeting of Stockholders.

We currently have nine directors on our Board. The current Class II directors are Matthew Fitzgerald, David McKenna and Robert Nipper, the current Class III directors are W. Matt Ralls, John Deane and Marty Stromquist and the current Class I directors are Michael McShane, Gurinder Grewal and Valerie Mitchell. All three of our current Class II directors are nominated for election to our Board as Class II directors at the Annual Meeting.

As indicated in our Second Amended and Restated Certificate of Incorporation (as amended by our Certificate of Amendment, effective as of December 1, 2020, our “Certificate of Incorporation”) our Board consists of such number of directors as determined from time to time by resolution adopted by a majority of the Board then in office. Any vacancies on the Board and any additional directorships resulting from an increase in the number of directors may be filled only by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum, or by a sole remaining director. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Because Advent International Corporation (“Advent”) controls a majority of the voting power of our Common Stock, it controls the election of our directors.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares represented by the proxy to elect as Class II directors the persons whose names and biographies appear below as nominees to the Board. All of the persons whose names and biographies appear below are currently serving as our directors. If any of the nominees should become unable to serve or for good cause will not serve as a director, it is intended that votes will be cast for a substitute nominee designated by the Board or the Board may elect to reduce its size. The Board of Directors has no reason to believe that the nominees named below will be unable to serve if elected. Each of the nominees has consented to being named in this Proxy Statement and to serve if elected.

Vote Required. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the three nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

		The Board of Directors unanimously recommends a vote FOR the election of the below Class II director nominees.

PROPOSAL 2: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has appointed GT as our independent registered public accounting firm for the year ending December 31, 2022. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of GT is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

GT also served as our independent registered public accounting firm for the year ended December 31, 2021. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of GT is expected to attend the Annual Meeting to respond to appropriate questions from stockholders and will be afforded the opportunity to make a statement at the Annual Meeting, if he or she desires to do so.

If the appointment of GT is not ratified by the stockholders, the Audit Committee will consider this fact and reconsider the appointment of the independent auditors for the year ending December 31, 2022. Even if the appointment of GT is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interests of the Company and our stockholders.

Vote Required. This proposal requires the approval of the affirmative vote of a majority of the votes properly cast. Abstentions and broker non-votes will have no effect with respect to this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of GT, we do not expect any broker non-votes in connection with this proposal.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee has reviewed the Company’s audited financial statements for the year ended December 31, 2021 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”).

The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the written disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company. Based on the foregoing discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, for filing with the SEC.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND OTHER MATTERS

The following table summarizes the fees that GT, our independent registered accounting firm who audited our financial statements for the fiscal year ended December 31, 2021, and PricewaterhouseCoopers LLP (“PwC”), who served as our independent registered public accounting firm prior to the selection of GT on March 22, 2021 and who audited our financial statements for the fiscal year ended December 31, 2020, billed to us for each of the last two fiscal years for audit services and other services:

Audit Fees. Audit fees consist of fees for the audit of our consolidated financial statements, the review of the unaudited interim financial statements included in our quarterly reports on Form 10-Q and other professional services provided in connection with regulatory filings or engagements.

Audit-Related Fees. Audit-related fees consist of fees for assurance and related services that are reasonably related to the performance of the audit and the review of our financial statements and which are not reported under “Audit Fees.”

Tax Fees. Tax fees comprise fees for a variety of permissible services relating to international tax compliance, tax planning and tax advice.

All Other Fees. All other fees relate to the use of an online technical research tool.

Audit Committee Pre-Approval Policy and Procedures. Our Audit Committee’s charter provides that the Audit Committee must consider and, in its discretion, pre-approve any audit or non-audit service provided to us by our independent registered public accounting firm. The Audit Committee may delegate authority to one or more subcommittees of the Audit Committee consistent with law and applicable rules and regulations of the SEC and the Nasdaq Stock Market (“Nasdaq”).

For the year ended December 31, 2021, all fees of GT were reviewed and pre-approved by the Audit Committee.

Change in Independent Registered Public Accounting Firm. On March 22, 2021, the Audit Committee dismissed PwC as the Company’s independent registered public accounting firm, effective immediately. This was approved by the Audit Committee on March 19, 2021. PwC’s audit reports on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2020 and 2019 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2020 and 2019, and the subsequent interim periods through March 22, 2021, there were (i) no disagreements (as described in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to PwC’s satisfaction, would have caused PwC to make reference thereto in their reports on the financial statements for such years, and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K.

On March 19, 2021, the Audit Committee approved the engagement of GT as the Company’s independent registered public accounting firm for the year ending December 31, 2021. This was not effective until PwC’s

15

dismissal on March 22, 2021. During the fiscal years ended December 31, 2020 and 2019, and the subsequent interim periods through March 22, 2021, neither the Company nor anyone acting on its behalf consulted with GT regarding any matter that (i) involved the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, in each case where a written report was provided or oral advice was provided that GT concluded was an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue, or (ii) was either the subject of a “disagreement”, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K, or a “reportable event”, as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

The Company previously disclosed the above-described change in independent registered public accounting firms on a Current Report on Form 8-K filed with the SEC on March 25, 2021 (the “Form 8-K”). As disclosed in the Form 8-K, the Company requested that PwC furnish the Company with a letter addressed to the SEC stating whether PwC agrees with the statements contained in the Form 8-K as they relate to PwC. A copy of PwC’s letter, dated March 24, 2021, was filed as an exhibit to the Form 8-K.

CORPORATE GOVERNANCE

GENERAL

Our Board of Directors has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics and charters for our Compensation, Nominating and Governance Committee and Audit Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics in the “Corporate Governance” section of the “Investors” page of our website located at http://ir.ncsmultistage.com, or by writing to our Secretary at our offices at NCS Multistage Holdings, Inc., 19350 State Highway 249, Suite 600, Houston, Texas 77070.

Code of Business Conduct and Ethics. We have a Code of Business Conduct and Ethics that applies to our employees, officers and directors, and all subsidiaries and entities controlled by us. A copy of the code is available in the “Corporate Governance” section of the “Investors” page of our website located at http://ir.ncsmultistage.com. Any amendments to or waivers from our code for our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, will be disclosed on our website promptly following the date of such amendment or waiver.

Corporate Governance Guidelines. Our Board has adopted Corporate Governance Guidelines in accordance with the Nasdaq corporate governance rules that serve as a flexible framework within which our Board and its committees operate. These guidelines cover a number of areas including: the duties and responsibilities of the Board; director independence; Board leadership structure; executive sessions; Chief Executive Officer evaluations; management development and succession planning; director nomination, qualification and election; director orientation and continuing education; Board agenda, materials, information and presentations; director access to company employees and independent advisers; Board communication with stockholders and others; director compensation; and annual board and committee performance evaluations. A copy of our Corporate Governance Guidelines is posted in the “Corporate Governance” section of the “Investors” page of our website located at http://ir.ncsmultistage.com.

BOARD COMPOSITION

Our business and affairs are managed under the direction of our Board of Directors. Our Board of Directors currently consists of nine members: Michael McShane, John Deane, Matthew Fitzgerald, Gurinder Grewal, David McKenna, W. Matt Ralls, Valerie Mitchell, Robert Nipper and Marty Stromquist. Following the Annual Meeting, we expect that the Board will consist of nine members. As indicated in our Certificate of Incorporation,

16

our Board consists of such number of directors as determined from time to time by resolution adopted by a majority of the total number of authorized directors. Any additional directorships resulting from an increase in the number of directors may be filled only by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum, or by the sole director if only one director then remains in office.

Our Board is divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting following election or such director’s death, resignation or removal, whichever is earliest to occur. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Because Advent controls a majority of the voting power of our Common Stock, it controls the election of our Directors.

DIRECTOR INDEPENDENCE AND CONTROLLED COMPANY EXEMPTION

Advent beneficially owns common stock representing more than 50% of the voting power of our Common Stock eligible to vote in the election of directors. As a result, we qualify as a “controlled company” and avail ourselves of certain “controlled company” exemptions under the Nasdaq corporate governance rules. As a controlled company, we are not required to have a majority of “independent directors” on our Board of Directors as defined under the Nasdaq rules, or have a compensation, nominating or governance committee composed entirely of independent directors.

Even though we qualify as a controlled company, we have a majority of independent directors serving on our Board of Directors and our Compensation, Nominating and Governance Committee is composed entirely of independent directors. Our Board has affirmatively determined that Messrs. McShane, Deane, Fitzgerald, Grewal, McKenna and Ralls and Ms. Mitchell are independent directors under the applicable Nasdaq rules. In evaluating and determining the independence of the directors, the Board considered that the Company may have certain relationships with its directors. Specifically, the Board considered that Messrs. McShane, Deane, Grewal and McKenna are or has been affiliated with, or is an operating partner of, Advent, which owns approximately 62.1% of our Common Stock as of December 31, 2021. The Board determined that this relationship does not impair their independence from us and our management.

We are not required to maintain compliance with Nasdaq’s director independence requirements and may choose to change our Board or committee composition or other arrangements in the future to manage our corporate governance in accordance with the controlled company exemption. If we cease to be a controlled company, we will be required to comply with Nasdaq’s corporate governance requirements applicable to listed companies, subject to a permitted “phase-in” period.

The “controlled company” exemption does not modify the independence requirements for the Audit Committee. Our Audit Committee is composed entirely of three independent directors.

DIRECTOR CANDIDATES

Each year, the Board proposes a slate of director nominees to stockholders for election at the annual meeting of stockholders. Stockholders may also recommend candidates for election to the Board, as described below. The Board has delegated the process of screening potential director candidates to the Compensation, Nominating and Governance Committee.

The Compensation, Nominating and Governance Committee is responsible for periodically reviewing with the Board the appropriate criteria that directors are required to fulfill in the context of the current make-up of the Board and the needs of the Board given the circumstances of the Company. In identifying and screening director

17

candidates, the Compensation, Nominating and Governance Committee considers whether the candidates fulfill the criteria for directors approved by the Board: integrity, objectivity, independence, sound judgment, leadership, courage and diversity of experience, including but not limited to diversity of gender, ethnicity and skill.

Invitations to serve as a nominee are extended by the Board itself via the Chairman of the Board and the Chairman of the Compensation, Nominating and Governance Committee.

To facilitate the search process for director candidates, the Board and the Compensation, Nominating and Governance Committee may consult with our directors and executives and outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders. Once potential candidates are identified, the Compensation, Nominating and Governance Committee screens candidates, evaluates candidates’ independence from us and potential conflicts of interest and determines if candidates meet the criteria approved by the Board for election as director.

The Compensation, Nominating and Governance Committee values the input of stockholders in identifying director candidates. The Compensation, Nominating and Governance Committee considers recommendations for Board candidates submitted by stockholders using substantially the same criteria it applies to recommendations from the Compensation, Nominating and Governance Committee, directors and members of management. Stockholders may submit recommendations by providing the person’s name and appropriate background and biographical information in writing to the Compensation, Nominating and Governance Committee at: NCS Multistage Holdings, Inc., 19350 State Highway 249, Suite 600, Houston, Texas 77070, Attn: Secretary.

COMMUNICATIONS WITH STOCKHOLDERS

Stockholders and other interested parties who would like to communicate with, or otherwise make his or her concerns known directly to the Chairman of the Board, the chairperson of any of the Compensation, Nominating and Governance Committee, Audit Committee, or to the non-management or independent directors as a group, may do so by addressing such communications or concerns to NCS Multistage Holdings, Inc., 19350 State Highway 249, Suite 600, Houston, Texas 77070, Attn: Chairman of the Board, who will forward such communications to the appropriate party. Such communications may be done confidentially or anonymously.

BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT

Our Corporate Governance Guidelines provide that the roles of Chairman of the Board and Chief Executive Officer may be separated or combined, and our Board exercises its discretion in combining or separating these positions as it deems appropriate in light of prevailing circumstances. Currently, the roles are separate, with Mr. McShane serving as Chairman of the Board and Mr. Nipper as a Board member and our Chief Executive Officer. We believe that we, like many United States (U.S.) companies, are well served by a flexible leadership structure. Our Board will continue to consider whether the positions of Chairman of the Board and Chief Executive Officer should be separated or combined at any given time as part of our succession planning process.

Our Board is responsible for overseeing our risk management process. In fulfilling this responsibility, our Board considers our general risk management strategy, assesses the most significant risks facing us, and oversees the implementation of risk mitigation strategies by management. Our Board considers specific risk topics, including risks associated with our annual operating plan, technology and capital structure in addition to market conditions and cyber security. In addition, the Board receives reports from management that includes discussion of risk and exposures involved in their respective areas of responsibility. Further, the Board is informed of developments that could affect our risk profile or other aspects of our business. Our Board is also apprised of particular risk management matters in connection with its general oversight and approval of corporate matters and significant transactions. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership

18

structure. Additionally, the Board oversees the Company’s policies and strategies relating to environmental, social and governance issues.

ATTENDANCE BY MEMBERS OF THE BOARD OF DIRECTORS AT MEETINGS AND EXECUTIVE SESSIONS

There were six meetings of the Board during the year ended December 31, 2021. During the year ended December 31, 2021, each director attended at least 75% of the aggregate of (i) all meetings of the Board and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director.

All directors are encouraged to attend our annual meetings of stockholders. All of the members of our Board attended the 2021 Annual Meeting of Stockholders. We anticipate that all of the members of our Board will attend the Annual Meeting this year.

The non-management directors meet regularly without members of management present in executive session. If any of the non-management directors do not qualify as an “independent director” as set forth in our Corporate Governance Guidelines, at least once a year an additional executive session is held, attended only by independent directors. Mr. McShane, as Chairman of the Board, presides over the regularly scheduled executive sessions at which he is present.

BOARD DIVERSITY

The following table presents the diversity statistics for our Board of Directors:

Board Diversity Matrix (as of December 31, 2021)

COMMITTEES OF THE BOARD

Our Board has established an Audit Committee and a Compensation, Nominating and Governance Committee. Each committee operates under a charter approved by our Board. Each committee has the composition and primary responsibilities described below. Members serve on these committees until their resignations or until otherwise determined by our Board. The charter of each committee is available on our website.

19

The members of each of the Board committees are set forth in the following chart.

AUDIT COMMITTEE

The primary purposes of our Audit Committee are to assist the Board in its oversight of our accounting and financial reporting processes and compliance with legal and regulatory requirements, including (i) producing the annual report of the Audit Committee required by the rules of the SEC and (ii) the oversight of:

Our Audit Committee is currently composed of Messrs. Fitzgerald and Ralls and Ms. Mitchell. Mr. Fitzgerald serves as the chairman. Messrs. Fitzgerald and Ralls each qualifies as an “audit committee financial expert” as such term has been defined by the SEC in Item 407(d)(5) of Regulation S-K. Our Board has affirmatively determined that Messrs. Fitzgerald and Ralls and Ms. Mitchell meet the definition of an “independent director” for the purposes of serving on the Audit Committee under applicable Nasdaq rules and Rule 10A-3 under the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Audit Committee is governed by a charter that complies with the Nasdaq rules.

The Audit Committee met four times during the year ended December 31, 2021.

COMPENSATION, NOMINATING AND GOVERNANCE COMMITTEE

The primary purposes of our Compensation, Nominating and Governance Committee are to: (i) produce the annual report of the Compensation, Nominating and Governance Committee required by the rules of the SEC, (ii) assist the Board’s oversight of the Company’s employee compensation policies and practices, including:

20

and (iii) assist the Board’s oversight of the Company’s governance policies and practices, including:

Our Compensation, Nominating and Governance Committee is currently composed of Messrs. Deane, McShane and Ralls. Mr. Deane serves as the chairman. Our Board has affirmatively determined that Messrs. Deane, McShane and Ralls meet the definition of an “independent director” for the purposes of serving on the committee under applicable Nasdaq rules. The Compensation, Nominating and Governance Committee is governed by a charter that complies with the Nasdaq rules.

The Compensation, Nominating and Governance Committee met four times during the year ended December 31, 2021.

Role of the Compensation Consultant. The Compensation, Nominating and Governance Committee has authority to retain compensation consulting firms to assist it in the evaluation of executive officer and employee compensation and benefit programs. The Compensation, Nominating and Governance Committee has retained Mercer LLC (“Mercer”), a wholly-owned subsidiary of Marsh & McLennan Companies, Inc., as its independent compensation advisor. Mercer provides an objective perspective as to the reasonableness of our executive compensation programs and practices and their effectiveness in supporting our business and compensation objectives. During 2021, Mercer advised the Compensation, Nominating and Governance Committee with respect to compensation trends and best practices, incentive plan design including competitive pay levels and individual pay decisions with respect to our directors, named executive officers and other executive officers.

In addition to executive compensation services provided to the Compensation, Nominating and Governance Committee, Mercer provided services to management which consisted primarily of human resources, compensation consulting services and insurance brokerage services. The Compensation, Nominating and Governance Committee has assessed the independence of Mercer pursuant to applicable SEC and Nasdaq rules and concluded that Mercer is independent and no conflict of interests exists.

Role of the Chief Executive Officer. Within the framework of the compensation programs approved by the Compensation, Nominating and Governance Committee and based on management’s review of market competitive positions, each year our Chief Executive Officer considers each other executive officer’s performance and makes a recommendation to the Compensation, Nominating and Governance Committee on base salary, annual bonus and equity awards for each named executive officer other than himself. The Chief Executive Officer participates in Compensation, Nominating and Governance Committee meetings at the Compensation, Nominating and Governance Committee’s request to provide background information regarding the Company’s strategic objectives and to evaluate the performance of and compensation recommendations for the other executive officers. The Compensation, Nominating and Governance Committee utilizes the information provided by the Chief Executive Officer along with input from Mercer and the knowledge and experience of the Compensation, Nominating and Governance Committee’s members in making compensation decisions. The Compensation, Nominating and Governance Committee may also consult other employees, including the executive officers, when making compensation decisions, but the Compensation, Nominating and Governance Committee is under no obligation to involve the executive officers in its decision-making process. The chair of the Compensation, Nominating and Governance Committee, with input from the Chairman of the Board of Directors, recommends the Chief Executive Officer’s compensation to the Compensation, Nominating and Governance Committee in an executive session not attended by the Chief Executive Officer and the Chief Executive Officer’s compensation is approved by the Board of Directors.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Policies for Approval of Related Person Transactions. Our Board of Directors has adopted a written policy relating to the approval of related person transactions. A “related person transaction” is a transaction or arrangement or series of transactions or arrangements in which we participate (whether or not we are a party) and a related person has a direct or indirect material interest in such transaction. Our Audit Committee will review and approve or ratify all relationships and related person transactions between us and (i) our directors, director nominees or executive officers, (ii) any 5% record or beneficial owner of our common stock or (iii) any immediate family member of any person or entity specified in (i), (ii) and (iii) above. The Audit Committee will review all related person transactions and, where the Audit Committee determines that such transactions are in our best interests, approve or ratify such transactions.

As set forth in the related person transaction policy, in the course of its review and approval or ratification of a related person transaction, the Audit Committee will, in its judgment, consider in light of the relevant facts and circumstances whether the transaction is, or is not inconsistent with, our best interests, including consideration of various factors enumerated in the policy.

Any member of the Audit Committee who is a related person with respect to a related person transaction under review or is otherwise not disinterested will not be permitted to participate in the discussions or approval or ratification of the transaction. However, such member of the Audit Committee will provide all material information concerning the transaction to the Audit Committee. Our policy also includes certain exceptions for related person transactions that need not be reported and provides the Audit Committee with the discretion to pre-approve certain related person transactions.

We did not have any related person transactions between us or our subsidiaries, and our directors, executive officers and holders of more than 5% of our Common Stock in the last fiscal year.

EXECUTIVE COMPENSATION

Overview

The discussion below includes a review of our compensation decisions with respect to 2021 and 2020 for our “named executive officers,” or “NEOs,” namely our principal executive officer and our two other most highly compensated executive officers. Our NEOs for 2021 were:

Robert Nipper, our Chief Executive Officer;

Tim Willems, our Chief Operations Officer; and

Ryan Hummer, our Chief Financial Officer.

In 2021 and 2020, our executive compensation program included a combination of base salary, annual incentive cash bonuses, restricted stock units, equivalent stock units and performance stock units. Our executive officers are also eligible to receive certain benefits, which include a 401(k) plan with matching contributions, provided that matching contributions were suspended for all employees from July 2020 to December 2021, an automobile allowance, life insurance and group health insurance, including medical, dental and vision insurance.

In connection with the challenging oil and gas industry market conditions that began in 2019 and which became more challenging in 2020 as a result of the Coronavirus disease 2019 (“COVID-19”) pandemic and reduced demand for oil and gas, our NEOs took voluntary pay reductions in 2019 and 2020, which remained in place through 2021. In July 2019, Messrs. Nipper and Willems elected to temporarily reduce their annual salary from $463,500 and $339,900 to $375,000 and $305,910, respectively. In April 2020, Mr. Nipper elected to temporarily further reduce his annual base salary to $300,000 and all other executive officers elected to temporarily reduce their annual base salary to $250,000. These voluntary pay reductions continued throughout 2021.

Furthermore, in February 2020 when the Compensation, Nominating and Governance Committee granted annual long-term incentive awards, it reduced the value of all grants by over 30% as compared to the prior year, including those made to directors and the NEOs. In addition, in February 2021, when the Compensation, Nominating and Governance Committee granted annual long-term incentive awards, it used the lower base salary level of employees to determine the number of awards to grant for the year.

Summary Compensation Table

The following table sets forth the compensation for 2020 and 2021 of the Company’s NEOs.

28

The grant date fair value of the performance stock units awards in 2021 equals $417,211, $200,074 and $200,074 for Messrs. Nipper, Willems and Hummer, respectively, and in 2020 equals $469,687, $198,203 and $198,203 for Messrs. Nipper, Willems and Hummer, respectively. Performance stock units provide the recipient the ability to earn shares of stock between 0% and 200% of the number of units granted based on the Company’s Total Shareholder Return (“TSR”) relative to our performance peer group over a performance period of three years. The TSR is calculated using the average closing share price over the 20 trading-day period ending on first day of the performance period and the average closing share price over the 20 trading-day period ending on last day of the performance period. The threshold performance level (25^th percentile relative TSR) starts to earn performance stock units, the mid-point performance level (50^th percentile relative TSR) earns 100% of the target performance stock units for the 2021 grant, and 65% of the target performance stock units for the 2020 grant, and the maximum performance level (90^th percentile relative TSR or greater) earns 200% of the target performance stock units. Payments are calculated by linear interpolation for performance between the threshold and mid-point and between the mid-point and maximum. If the maximum payout were to be achieved with respect to the performance stock unit awards awarded in 2021, the grant date fair value of such awards, computed by multiplying two times the Common Stock price on the day of the grant by the number of PSUs granted, for Messrs. Nipper, Willems and Hummer would be equal to $485,716, $232,925 and $232,925, respectively, and in 2020, the grant date fair value of such awards for Messrs. Nipper, Willems and Hummer would be equal to $781,617, $329,834 and $329,834, respectively.

Outstanding Equity Awards as of December 31, 2021

The following table sets forth certain information about outstanding equity awards held by our NEOs as of December 31, 2021.

Employment Agreements

We are currently party to employment agreements with each of our NEOs. The material provisions of each such agreement are described below.

On August 3, 2017, we entered into employment agreements with each of Robert Nipper, our Chief Executive Officer, Tim Willems, our Chief Operations Officer, and Ryan Hummer, our Chief Financial Officer (each, an “Executive”). The agreements provide for an initial term of three years which will automatically renew at the end of such period for additional one year-terms. The agreements provide that the Executives will receive an annualized base salary subject to review by our Board (as of December 31, 2021, the annual base salary was $300,000 for Mr. Nipper, $250,000 for Mr. Willems and $250,00 for Mr. Hummer). The agreements also provide that the Executives are eligible to receive annual bonuses with targets of 105%, 80% and 75% of base salary for

30

each of Messrs. Nipper, Willems and Hummer, respectively, and up to a maximum bonus of 200% of base salary for each Executive, based on achievement of annual performance targets established by the Board each year.

Either we or the Executive may terminate the agreement at any time upon written notice. We may terminate the Executive’s employment for death, disability, for cause, without cause or upon the close of business on the last day of the term of the employment agreement by giving notice of non-renewal of the agreement 90 days prior to the expiration of the term. The Executive may resign following a good reason event or without a good reason event.

If we terminate an Executive’s employment without cause, the Executive resigns following a good reason event or we elect not to renew the employment agreement at the end of the term, then, in addition to any accrued but unpaid base salary and accrued but unpaid annual bonus for the year prior to the year of termination, we must provide the Executive with, subject to Executive’s execution of a release of claims, such release becoming effective and Executive’s continued compliance with the restricted covenants contained in the agreement, (i) one (1) times (two (2) times in the case of Mr. Nipper) the sum of (A) base salary and (B) the Executive’s target bonus, payable over the twelve-month period following the date of the termination; (ii) a lump sum payment equal to the pro-rated annual bonus the Executive would have received for the year of termination, based on actual performance for such year; (iii) continued vesting of unvested equity awards in accordance with the applicable existing vesting schedules; and (iv) subject to the Executive’s timely election for coverage under COBRA, a cash payment equal to the full premium for actively employed executives for up to 24 months. If such termination of employment occurs within 24 months following a Change of Control (as defined in the employment agreements), in addition to any accrued but unpaid base salary and accrued but unpaid annual bonus for the year prior to the year of termination, in lieu of the benefits described above, we must provide the Executive with, subject to Executive’s execution of a release of claims, such release becoming effective and Executive’s continued compliance with the restricted covenants contained in the agreement, (i) two (2) times (three (3) times in the case of Mr. Nipper) the sum of (A) base salary and (B) the Executive’s target bonus, payable over the twelve-month period following the date of the termination; (ii) a lump sum payment equal to the pro-rated annual bonus the Executive would have received for the year of termination, based on actual performance for such year; (iii) full vesting of unvested equity awards; and (iv) subject to the Executive’s timely election for coverage under COBRA, a cash payment equal to the full premium for actively employed executives for up to 24 months. In addition, any cash severance payable to an Executive will be calculated based on the greater of the Executive’s base salary prior to any salary reduction or the then-current base salary at the time of termination.

If an Executive’s employment is terminated as a result of death, disability, voluntary resignation other than following a good reason event, or by us for cause, the Executive shall be entitled to receive accrued but unpaid base salary through the date of termination and any accrued but unpaid annual bonus for the year prior to the year of termination. In addition, if the Executive’s employment terminates as a result of death or disability, the Executive or Executive’s legal representatives shall be entitled to a lump sum amount equal to the pro-rated annual bonus the Executive would have received for the year of termination, based on actual performance.

For purposes of the agreements, good reason event means, without an Executive’s consent, (i) any material diminution in Executive’s responsibilities, authorities, title, reporting structure or duties, (ii) any material reduction in Executive’s base salary or target annual bonus opportunity (except in the event of an across the board reduction in base salary or target annual bonus opportunity of up to 10% applicable to substantially all of our senior executives), (iii) a relocation of Executive’s principal place of employment by more than 50 miles from the location on the effective date of the agreement and such place is more than 50 miles from Executive’ principal residence, or (iv) a material breach by us of any provisions of the agreement; provided that Executive has given us written notice of such event within 60 days following the occurrence of such event and we do not cure the event within 60 days following such notice. For purposes of the agreements, cause means (i) Executive’s indictment for, conviction of, or a plea of guilty or no contest to, any indictable criminal offence or any other criminal offence involving fraud, misappropriation or moral turpitude, (ii) Executive’s continued failure to

31

materially perform Executive’s duties under the employment agreement (for any reason other than illness or physical or mental incapacity) or a material breach of fiduciary duty, (iii) Executive’s theft, fraud, or dishonesty with regard to us or any of our affiliates or in connection with Executive’s duties, (iv) Executive’s material violation of our code of conduct or similar written policies, (v) Executive’s willful misconduct unrelated to us or any of our affiliates having, or likely to have, a material negative impact on us or any of our affiliates (economically or its reputationally), (vi) an act of gross negligence or willful misconduct by the Executive that relates to our or any of our affiliates affairs, or (vii) material breach by Executive of any provisions of the employment agreement.

The agreements include perpetual confidentiality provisions, a company non-disparagement provision, as well as provisions relating to non-competition and non-solicitation that apply during employment and for one year following a termination of employment.

Potential Payments upon Termination of Employment or Termination Following a Change of Control

Our NEOs are entitled to receive severance payments and acceleration and/or continued vesting of time-based vesting equity awards upon termination of employment by us other than for cause or by the NEO for good reason or a change of control. See “—Employment Agreements” for a description of these potential payments upon termination of employment.

Nonqualified Deferred Compensation Plan

The Nonqualified Deferred Compensation (“NQDC”) Plan provides an income deferral opportunity for executive officers and certain managers of the Company who qualify for participation. The NQDC Plan is unfunded, but we may elect to set aside funds in a Rabbi trust to cover the benefits under the plan, though such funds remain subject to the claims of our creditors.

Participants in the NQDC Plan may make an advance election each year to defer up to 80% of their base salary, bonus and commissions. Participants are immediately 100% vested in their benefits under the NQDC Plan.

Participants may choose from a variety of investment choices to invest their deferrals over the deferral period. Participants earn a rate of return on their NQDC Plan account that approximates the rate of return that would be provided by certain specified mutual funds that participants may designate from a list of available funds.

Benefits are paid in either a lump-sum or in equal annual installments over various timeframes provided by the NQDC Plan, as elected by the participant. Generally, benefits that are due as a result of a termination of service commence or are paid after termination. However, only participants who with at least 5 years of service at termination will be eligible to receive or continue receiving installment distributions following termination.

Annual Cash Incentive Bonus

We offer our NEOs the opportunity to earn annual cash incentive awards to compensate them for attaining short-term Company goals. Each NEO has an annual target bonus that is expressed as a percentage of his annual base salary, as discussed above in “—Employment Agreements.”

Our annual cash incentive awards are intended to be performance-based and, for 2020 and 2021, were determined based upon the performance criteria of Adjusted EBITDA and contained a minimum level requirement whereby if the minimum level is not met, there would be no annual cash incentive award earned. The 2020 and 2021 annual cash incentive bonus programs were approved by the Compensation, Nominating and Governance Committee. For 2021, the annual cash incentives under our bonus program earned at a level between the minimum level and the target level and, for 2020, no annual cash incentives were earned.

32

Director Compensation

Directors who are employed by us or who are or were full-time investment professionals of Advent are not eligible to receive compensation for their service on our Board. All other members of our Board received a one-time stock option or restricted stock unit grant upon their election to the Board, as well as annual grants of restricted stock units. In addition, we pay annual director, committee and per meeting fees. All of our directors are also reimbursed for reasonable out-of-pocket travel expenses incurred in connection with attendance at Board and committee meetings and other Board-related activities.

In 2021, we paid our eligible directors a quarterly retention fee of $12,500, and an additional fee of $2,000 per Board or committee meeting attended. Such directors also received an annual award of restricted stock units in an amount of $125,000, which vests on the one-year anniversary of the grant date and, at the director’s election, may be subject to delayed settlement. The chair of the Audit Committee and the chair of the Compensation, Nominating and Governance Committee each received an additional quarterly fee of $4,500. The Chairman of the Board also received an additional $12,500 quarterly fee. In addition, new directors received an initial grant of restricted stock units in an amount of $100,000, which vest in three equal installments beginning on the first anniversary of the grant date.

We reimburse our directors for certain expenses incurred in connection with attending Board and committee meetings as well as other related events, including travel, hotel accommodations, meals and other incidental expenses for the directors. The compensation for our directors who were not employees for fiscal 2021 was as follows:

Equity Incentive Plans

We maintain two equity incentive plans for the benefit of our employees, directors and other service providers: the 2012 Equity Incentive Plan (the “2012 EIP”) and Amended and Restated 2017 Equity Incentive Plan, as amended by the First Amendment (the “2017 EIP”). We do not intend to issue future awards under the 2012 EIP.

33

The 2017 EIP was initially adopted in connection with our IPO and provides for awards of stock options, stock appreciation rights, restricted stock awards, restricted stock units, stock awards and performance awards. Awards under the 2017 EIP may be granted to any employee, non-employee director, consultant or other personal service provider to the Company or any of our subsidiaries. The 2017 EIP is administered by a plan administrator, which is the Compensation, Nominating and Governance Committee or such other committee of the Board or the Board as a whole, in each case as determined by the Board.

Employee Stock Purchase Plans

We maintain Employee Stock Purchase Plans for U.S. and non-U.S. employees. The purpose of the Employee Stock Purchase Plans is to provide employees with an opportunity to acquire a proprietary interest in the Company through the purchase of shares of our Common Stock. In general, all employees of the Company and certain subsidiaries are eligible to participate in the Employee Stock Purchase Plan applicable to their jurisdiction, subject to certain exceptions for employees who have been employed for less than 30 days, whose customary employment is for less than 20 hours per week or whose customary employment is for not more than five months in a calendar year. The Employee Stock Purchase Plans for U.S. and non-U.S. employees were suspended for offering periods beginning on July 1, 2019.
