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 2025 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 2025 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 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, to sign, date and return the 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.

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 May 27, 2026. 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 2025 Annual Report available to our stockholders electronically via the Internet. On or about April 2, 2026, we sent by mail or email to our stockholders of record, as of the Record Date, a Notice of Internet Availability of Proxy Materials (the "Internet Notice") containing instructions on how to access this Proxy Statement and our 2025 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 2025 Annual Report. The Internet Notice also instructs 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 2026 Annual Meeting of Stockholders."

QUESTIONS AND ANSWERS ABOUT THE 2026 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 March 30, 2026 (the Record Date) 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 2,624,523 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 the 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 may write to us at the address below to request a separate set of proxy materials or Internet Notice, as applicable:

NCS Multistage Holdings, Inc.

19350 State Highway 249, Suite 600

Houston, Texas 77070

Attn: Secretary

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 the 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 March 30, 2026, 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.

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 26, 2026.

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.

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?

Proposal		Votes Required		Effect of Votes Withheld / Abstentions and Broker Non-Votes
Proposal 1: Election of Directors		The plurality of the votes cast. This means that the two nominees receiving the highest number of affirmative "FOR" votes will be elected as Class III Directors.		Votes withheld and broker non-votes will have no effect on this proposal.
Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm		The affirmative vote of a majority of the votes cast.		Abstentions will have no effect on this proposal. Brokers have discretion to vote on this proposal.
Proposal 3: Approval of the Advisory Vote on Named Executive Officer Compensation		The affirmative vote of a majority of the votes cast.		Abstentions and broker non-votes will have no effect on this proposal.

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 all of the other proposals 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 Grant Thornton LLP 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 are included to determine whether a quorum is present. However, on the proposals regarding the election of directors and the approval of the advisory vote on named executive officer compensation, 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 on 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, two Class III directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2029 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 two nominees receiving the highest number of affirmative "FOR" votes will be elected as Class III 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 III, whose term will expire at the Annual Meeting; Class I, whose term will expire at the 2027 Annual Meeting of Stockholders; and Class II, whose term will expire at the 2028 Annual Meeting of Stockholders.

We currently have seven directors on our Board. The current Class III directors are John Deane and W. Matt Ralls, Class I directors are Michael McShane, Gurinder Grewal and Valerie Mitchell, and Class II directors are Robert Nipper and Ryan Hummer.

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 III 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 two nominees receiving the highest number of affirmative "FOR" votes will be elected as Class III 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 III director nominees.

NOMINEES FOR CLASS III DIRECTORS (TERMS TO EXPIRE AT THE 2026 ANNUAL MEETING)

He previously served on the boards of Culligan International Group, BOS Solutions Ltd., Oleoducto Central S.A. (Ocensa), Quala and RGL Reservoir Management Inc. Mr. Grewal received an H.B.A. from the Richard Ivey School of Business at the University of Western Ontario and an M.B.A. from Harvard Business School. We believe that Mr. Grewal's experience in the private equity and energy industries qualify him to serve as one of our directors.
	VALERIE MITCHELL
	Ms. Mitchell (age 54) has served as one of our directors since August 2019. She is the President of Troy Energy, a position she has held since March 2020. Since June 2022, she has served on the board of directors of Freehold Royalties and is a member of the Governance, Nominating, and Compensation Committee and the Reserves Committee. Previously, Ms. Mitchell served as the Chief Executive Officer and member of the board of directors of Corterra Energy LLC from December 2016 through November 2019. Prior to that, she served in various positions with Newfield Exploration Company from 2004 through 2016, including as the Vice President, Mid-Continent from February 2015 through August 2016, Vice President, Corporate Development from May 2014 through January 2015 and General Manager, Mid-Continent Region from December 2011 through April 2014. She holds a B.S. in Chemical Engineering from the University of Missouri. Ms. Mitchell has over 20 years of operational leadership experience in the oil and natural gas industry. Ms. Mitchell is also a member of the National Association of Corporate Directors and holds a NACD.D certification. We believe that Ms. Mitchell's management experience and expertise in the oil and natural gas industry qualify her to serve as one of our directors.

CONTINUING MEMBERS OF THE BOARD: CLASS II DIRECTORS (TERMS TO EXPIRE AT THE 2028 ANNUAL MEETING)

The current members of the Board of Directors who are Class II directors and their principal occupations and business experience, for at least the past five years are as follows:

	ROBERT NIPPER
	Mr. Nipper (age 61) has served as one of our directors since December 2012. Mr. Nipper co-founded NCS and served as our Chief Executive Officer from November 2016 until November 2022 and from December 2012 until April 2016. He previously served as our Executive Chairman from April 2016 until February 2017. He has more than 30 years of industry experience and has invented several patented technologies relating to downhole oil and natural gas and geothermal service equipment. Prior to founding NCS, Mr. Nipper spent 18 years with Tri-State Oil Tools Inc. and Baker Hughes, including various operations and sales management positions. Prior to leaving Baker Hughes, he held the position of North American Marketing Manager. We believe Mr. Nipper's extensive experience as the co-founder of NCS and over 30 years of industry experience provide insight and informational knowledge about our company and qualify him to serve as one of our directors.
	RYAN HUMMER
	Mr. Hummer (age 48) is our Chief Executive Officer and has served as a member of our Board since November 2022. He previously served as our Chief Financial Officer and Treasurer from March 2020 until November 2022 and our Chief Financial Officer from November 2016 until March 2020.

Mr. Hummer holds a B.S. in Economics from the Wharton School of the University of Pennsylvania. We believe Mr. Hummer's experience with the Company and in the industry provides insight and informational knowledge about our company and qualify him to serve as one of our directors.

We believe that all of our current Board members possess the professional and personal qualifications necessary for Board service, and we have highlighted particularly noteworthy attributes for each Board member in the individual biographies above. There are no family relationships between or among our directors and executive officers.

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

Our Audit Committee has appointed Grant Thornton LLP ("GT") as our independent registered public accounting firm for the year ending December 31, 2026. 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 since the fiscal year 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 registered public accounting firm for the year ending December 31, 2026. Even if the appointment of GT is ratified, the Audit Committee retains the discretion to appoint a different independent registered public accounting firm 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 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.

RECOMMENDATION OF THE BOARD OF DIRECTORS

	The Board of Directors unanimously recommends a vote FOR the Ratification of the Appointment of Grant Thornton LLP as our Independent Registered Public Accounting Firm.

PROPOSAL 3: ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

Our Board of Directors proposes that stockholders provide advisory (non-binding) approval every year of the compensation of our named executive officers, as disclosed in this Proxy Statement in accordance with the SEC's rules (commonly known as a "say-on-pay" proposal). Our next advisory vote on named executive officer compensation will occur at our 2027 Annual Meeting. Inclusion of a "say-on-pay" proposal is required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act") and provides our stockholders the opportunity to express their views regarding the compensation of our named executive officers. The Dodd-Frank Act also requires us to hold an advisory vote at least once every six years to determine how frequently stockholders should vote on named executive officer compensation, with our next frequency vote to be held by our 2029 Annual Meeting.

Our executive officer compensation program is designed to attract, motivate, and retain our executive officers, who are critical to our success, and ensure alignment of such persons with stockholders. We believe our executive officer compensation programs also are structured appropriately to support our Company and business. Under this program, our officers are rewarded for their service to the Company and the realization of increased stockholder value. Please read the "Executive Compensation" section below for additional details about our executive officer compensation program, including information about the fiscal year 2025 compensation of our named executive officers.

The Compensation, Nominating and Governance Committee regularly reviews our compensation program to ensure the program is designed to reward executives for long-term strategic management and the enhancement of stockholder value and comports with current market practices. We believe our executive compensation program achieves the following objectives:

•

To attract, motivate, and retain executives who can achieve corporate strategic plans;

•

To reward outstanding performance to achieve these goals without subjecting the Company to excessive or unnecessary risk; and

•

To align the interests of executives with the long-term interests of stockholders.

The Compensation, Nominating and Governance Committee evaluates the Company's compensation policies and practices to ensure that they are consistent with good governance principles. Below are highlights of our governance practices:

What We Do		What We Don't Do
Performance-based compensation		NO "single-trigger" change of control severance payments
Balance of short-and long-term incentives		NO guaranteed bonuses with cap of 200% of target for executives
Robust stock ownership guidelines		NO significant compensation in the form of perquisites for executives
Consider peer group reports when establishing compensation		NO evergreen provisions or liberal share recounting in the equity incentive plan
Maintain Nasdaq compliant incentive-based recovery policy		NO excise tax gross-ups
Independent compensation consultant		NO repricing of underwater options

The Company's compensation program for its named executive officers has been thoughtfully designed to support the Company's long-term business strategies and drive creation of stockholder value. The Compensation, Nominating and Governance Committee designed the program to balance incentivizing necessary short-term tactical measures and the continued cultivation of longer-term corporate opportunities. Specifically, the program consists of performance-based compensation and long-term incentives, including:

•

Annual Cash Incentive Bonus Aligned with Performance. The Company's annual cash incentive bonus was based on two components: (i) Adjusted EBITDA, a measure of Company profitability, and (ii) individual performance, based on each executive's achievement of personal goals. The annual cash incentive bonus also contained a minimum level performance requirement. If the minimum Adjusted EBITDA level is not achieved, no annual cash incentive award would be earned for the Company component. In addition, the bonus structure has a maximum level cap of 200% of the target bonus. Based on the Company's 2025 performance, executives earned annual cash incentive awards at a level above the target goals.

•

Long-Term Incentives Linked to Shareholder Value. Long-term incentive awards comprise the largest portion of pay for our named executive officers. The Company's long-term incentive awards consist of stock-settled restricted stock units, cash-settled restricted stock units and performance stock unit awards, which reward the named executive officers for financial returns, absolute stock price appreciation, and relative shareholder return performance. Performance stock units vest based upon the achieved Company Total Shareholder Return ("TSR") relative to the TSR of a peer group over a specified three year period.

We are asking our stockholders to indicate their support for the named executive officer compensation as described in this Proxy Statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we ask our stockholders to vote "FOR" the following resolution at the Annual Meeting:

"RESOLVED, that the stockholders of NCS Multistage Holdings, Inc. approve, on an advisory basis, the compensation of the named executive officers, as disclosed in its Proxy Statement for the 2026 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Summary Compensation Table and the other related tables and disclosure."

The say-on-pay vote is advisory, and therefore not binding on the Company or our Board. We value the opinions of our stockholders and to the extent there is any meaningful vote against the named executive officer compensation as disclosed in this Proxy Statement, we will review our stockholders' concerns and the Board and Compensation, Nominating and Governance Committee will consider actions to address those concerns.

Vote Required. This proposal requires the approval of the affirmative vote of a majority of the votes cast. Abstentions and broker non-votes will have no effect with respect to this proposal. Brokers do not have discretionary authority to vote on the advisory vote on named executive officer compensation.

RECOMMENDATION OF THE BOARD OF DIRECTORS

	The Board of Directors unanimously recommends a vote FOR the Approval of the Advisory Vote on Named Executive Officer Compensation.

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, 2025 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, 2025, for filing with the SEC.

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 the 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.

Information Security. Maintaining and protecting the Company's information and trade secrets is of utmost importance. The Audit Committee of our Board monitors cybersecurity related matters and periodically receives an information technology and cybersecurity update from management during the year. During these meetings, management presents to the Audit Committee programs being implemented to mitigate cybersecurity risks. The Company works with outside subject matter experts to assist in analyzing and improving potential cybersecurity weaknesses. In addition, employees are provided with online training courses to build awareness around potential cybersecurity scams and tested periodically to maintain their focus in this important area. The Company maintains cybersecurity insurance to defray costs associated with an information security breach, should one occur.

Compliance Framework. During 2025, the Board continued its oversight on environmental, social and corporate governance ("ESG") as well as maintained robust Anti-Bribery, Export-Import Sanctions, Code of Conduct and related corporate governance policies. We currently intend to issue a 2025 ESG update report in 2026 on our website.

Incentive-Based Compensation Policy. We maintain a policy on incentive compensation-based recovery, which meets the requirements of Nasdaq listing standards and Section 10D of the United States Securities Exchange Act of 1934, as amended (the "Exchange Act"). The policy requires the recoupment of incentive-based compensation paid to certain current and former executive officers in the event that the Company is required to restate its financial results due to the Company's material non-compliance with any financial reporting requirement under the securities laws. The Policy is administered by the Compensation, Nominating and Governance Committee of the Board.

BOARD COMPOSITION

Our business and affairs are managed under the direction of our Board of Directors. Our Board of Directors currently consists of seven members: Michael McShane, John Deane, Gurinder Grewal, W. Matt Ralls, Valerie Mitchell, Robert Nipper and Ryan Hummer. Following the Annual Meeting, we expect that the Board will continue to consist of seven members. As indicated in 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 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

Even though we qualify as a "controlled company" under the applicable Nasdaq listing rules (as described below), we have a majority of independent directors serving on our Board of Directors. Our Audit Committee and our Compensation, Nominating and Governance Committee are each composed entirely of independent directors, satisfying the applicable Nasdaq and SEC requirements. Our Board has affirmatively determined that Messrs. McShane, Deane, Grewal, 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 Mr. Grewal served as Managing Director at Advent until 2021 and that neither Mr. McShane nor Mr. Deane has been affiliated with Advent in the last five years. See - Proposal 1: Election of Directors for further biographical information for each director. The Board determined that these relationships do not impair their independence from us and our management.

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." As a controlled company, we are not required to have a majority of independent directors on our Board, or have a compensation or nominating committee composed entirely of independent directors. However, as stated above, most of the directors serving on our Board are independent. Our Audit Committee and Compensation, Nominating and Governance Committee are each composed entirely of independent directors.

We 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 candidates, the Compensation, Nominating and Governance Committee considers whether the candidates fulfill the requisite criteria for board membership 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 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 the Company, assesses any 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 applied 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 ("Chair") and Mr. Hummer 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 believes our current structure fosters effective governance and oversight of the Company, and allows the Chief Executive Officer to focus on strategic planning and execution of the organization's day-to-day performance while the Chair leads the Board in its fundamental oversight role.

There may however be unique circumstances, such as a change in executive or Board composition or a significant strategic development, under which the Board may determine that stockholders are best served by combining the roles of Chair and Chief Executive Officer and appointing a strong lead independent director with robust duties and responsibilities. In the event that the roles of the Chief Executive Officer and Chair are combined, we anticipate that the Board would appoint a strong lead independent director with a well-defined role similar to the responsibilities undertaken by our current Chair. We also expect the Board would engage with stockholders regarding such changes to its leadership.

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 include discussions of risk and exposures in various areas of responsibility. Further, the Board is informed of developments that could affect our short-term and long-term 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 structure. The Company consults with outside advisors and experts to anticipate future threats and trends, as needed.

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, 2025. During the year ended December 31, 2025, 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 2025 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.

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.

The members of each of the Board committees as of the date of this proxy statement 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:

•

audits of the financial statements of the Company;

•

the integrity of the financial statements;

•

our processes relating to risk management and the conduct and systems of internal control over financial reporting and disclosure controls and procedures;

•

the qualifications, engagement, compensation, independence and performance of our public accounting firm as the Company's auditor, and the auditor's conduct of the annual audit of our financial statements and any other services provided to the Company; and

•

the performance of our internal audit function.

Our Audit Committee is currently composed of Messrs. McShane and Ralls and Ms. Mitchell. Mr. McShane serves as the chairman. Messrs. McShane and Ralls each qualify 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. McShane 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 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, 2025.

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:

•

determine and approve the compensation of our Chief Executive Officer and other executive officers;

•

evaluate the performance of our Chief Executive Officer and other executive officers against corporate goals and objectives;

•

review and approve incentive compensation and equity compensation policies and programs;

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

•

identify and screen individuals qualified to serve as directors and recommend to the Board candidates for nomination for election at the annual meeting of stockholders or to fill Board vacancies;

•

develop, recommend to the Board and review our Corporate Governance Guidelines;

•

coordinate and oversee the annual self-evaluation of the Board and its committees; and

•

review on a regular basis the overall corporate governance of the Company and recommend improvements for approval by the Board where appropriate.

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, 2025.

Role of the Compensation Consultant. The Compensation, Nominating and Governance Committee has authority to retain compensation consulting firms to assist 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 2025, 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 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.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table shows information as of March 30, 2026, regarding the beneficial ownership of our Common Stock by:

•

each person or group who is known by us to beneficially own more than 5% of our Common Stock;

•

each member of our Board and each of our named executive officers identified in our Annual Report on Form 10-K for the year ended December 31, 2025; and

•

all members of our Board and our executive officers as a group.

Beneficial ownership of shares is determined under rules of the SEC and generally includes any shares over which a person exercises sole or shared voting or investment power. Except as noted by footnote, and subject to community property laws where applicable, we believe based on the information provided to us that the people and entities named in the table below have sole voting and investment power with respect to all shares of our Common Stock shown as beneficially owned by them. Percentage of beneficial ownership is based on 2,624,523 shares of Common Stock outstanding as of the Record Date. Shares of Common Stock subject to options currently exercisable or exercisable within 60 days of the Record Date, and shares of Common Stock underlying restricted stock units subject to vesting and settlement within 60 days of the Record Date, are deemed to be outstanding and beneficially owned by the person holding the options or restricted stock units for the purposes of computing the percentage of beneficial ownership of that person and any group of which that person is a member, but are not deemed outstanding for the purpose of computing the percentage of beneficial ownership for any other person. Except as otherwise indicated, the people named in the table below have sole voting and investment power with respect to all shares of capital stock held by them.

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 two completed fiscal years.

________________

(1)	Represents annual base salary paid pursuant to the terms of each NEO's employment agreement. See "-Employment Agreements" for a description of the NEO's employment agreements.

(2)	Represents a one-time discretionary bonus in recognition of contributions to corporate objectives, awarded in 2024 to each of Messrs. Hummer, Willems and Morrison and in 2025 to Mr. Willems.

(3)

Represents the aggregate grant date fair value, computed in accordance with the Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation-Stock Compensation ("ASC 718"), of (a) time vested restricted stock unit awards and equivalent stock units, which is equal to the number of shares awarded valued at the closing price of our Common Stock on the date of grant, and (b) performance stock unit awards that is based on the probable outcome of the performance condition.

The restricted stock units and equivalent stock units awarded in the first quarter of 2025 vest in three equal annual installments beginning February 28, 2026. The restricted stock units and equivalent stock units awarded in the first quarter of 2024 vest in three equal annual installments beginning February 28, 2025. The equivalent stock units settle in cash and represent the economic equivalent of one share of Common Stock, provided that the amount of cash settled for any equivalent stock unit will not exceed the maximum payout established by the Compensation, Nominating and Governance Committee, which is approximately two times the Common Stock price on or around the date of grant. In accordance with ASC 718, since the equivalent stock units are liability-classified awards, or cash settled, the compensation expense is remeasured each reporting period at fair value based upon the closing price of our Common Stock until the awards are settled.

Performance stock units provide the recipient the ability to earn shares of stock based on the Company's TSR relative to a 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 the first day of the performance period and the average closing share price over the 20 trading-day period ending on the last day of the performance period.

For the performance stock units granted in 2025 and 2024, the threshold performance level (25^th percentile relative TSR) earns 50% of the target performance stock units, the mid-point performance level (50^th percentile relative TSR) earns 100% of the target performance stock units and the maximum performance level (75^th percentile relative TSR or greater) earns 125% of the target performance stock units. The number of shares of Common Stock to be issued is calculated by linear interpolation for performance between the threshold and mid-point and between the mid-point and maximum.
The grant date fair value of the performance stock units awards for Messrs. Hummer, Willems, and Morrison, respectively, in 2025 equals $351,695, $158,492 and $156,306, and in 2024 equals $357,196, $181,072 and $178,598, in each case as determined by ASC 718 and based on the probable outcome of the performance condition.
If the maximum payout were to be achieved with respect to the performance stock unit awards granted in 2025, the grant date value of such awards, computed by multiplying 1.25 times the Common Stock price on the day of the grant by the number of performance stock units granted, for Messrs. Hummer, Willems, and Morrison would be equal to $444,125, $200,148 and $197,375, respectively, and in 2024, the grant date value of such awards, computed by multiplying 1.25 times the Common Stock price on the day of the grant by the number of performance stock units granted, for Messrs. Hummer, Willems, and Morrison would be equal to $448,834, $227,525 and $224,417, respectively.

See the "-Annual Cash Incentive Bonus" section below for more details." For fiscal year 2025, the target cash incentive bonus for each of Messrs. Hummer, Willems, and Morrison, respectively, was 125%, 90% and 80% of base salary.

Hummer and Morrison, and for the performance stock units granted in 2024 and 2025 to Messrs. Hummer, Willems and Morrison. For Messrs. Hummer and Morrison, respectively, the 18,442 and 4,781 performance stock units granted on November 1, 2022 will settle for between zero and two shares of Common Stock in the first quarter of 2026; for Mr. Willems, the 5,485 performance stock units granted in the first quarter of 2023 will settle for between zero and two shares of Common Stock in the first quarter of 2026; for Messrs. Hummer, Willems and Morrison, respectively, the 23,392, 11,858 and 11,696 performance stock units granted in the first quarter of 2024 will settle for between zero and 1.25 shares of Common Stock in the first quarter of 2027; for Messrs. Hummer, Willems and Morrison, respectively, the 14,479, 6,525 and 6,435 performance stock units granted in the first quarter of 2025 will settle for between zero and 1.25 shares of Common Stock in the first quarter of 2028. During the first quarter of 2026, the Compensation, Nominating and Governance Committee certified the performance of the performance stock units granted in 2023 to Mr. Willems, or late in 2022 to Messrs. Hummer and Morrison, was above the target performance and thus 30,844, 9,173, and 7,996 shares of Common Stock were settled for those awards to Messrs. Hummer, Willems and Morrison, respectively. See footnote (2) to the Summary Compensation Table for additional details regarding the performance stock units.

Option Grant Practices

We have not granted stock options to our employees for many years. We therefore (i) do not grant, and have not granted, stock options in anticipation of the release of material nonpublic information, (ii) we do not time, and have not timed, the release of material nonpublic information based on stock option grant dates or for the purpose of affecting the value of executive compensation and (iii) we do not take, and have not taken, material nonpublic information into account when determining the timing and terms of stock options. As stock options have not been an element of employee compensation for a significant amount of time, we do not have a formal policy with respect to the timing of stock option grants, and we did not grant stock options or stock appreciation rights in 2025.

Employment Agreements

We are currently party to employment agreements with each of our NEOs (each referred to as an "Executive" herein), which were amended and restated on July 17, 2024. The material provisions of each such agreement are described below.

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, 2025, the annual base salary was $475,000 for Mr. Hummer, $375,950 for Mr. Willems and $370,800 for Mr. Morrison). The agreements also provide that the Executives are eligible to receive annual bonuses with targets of 125%, 90% and 80% of base salary for each of Messrs. Hummer, Willems and Morrison, 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. Hummer) 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. Hummer) 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 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 unvested 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.

Annual Cash Incentive Bonus

We offer our NEOs the opportunity to earn annual cash incentive awards to compensate for the attainment of 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 2024 and 2025, were largely determined based upon the performance criteria of Adjusted EBITDA. The 2024 and 2025 annual cash incentive bonus programs were approved by the Compensation, Nominating and Governance Committee.

For 2025, our annual cash incentive bonus had a company component, measured based on the generation of Adjusted EBITDA, that was weighted as 75% of the target bonus, and a personal component, that was weighted as 25% of the target bonus. The personal component was based on objective measures of both Company and personal performance. The personal component consisted of group goals applicable to all executives, including safety metrics, free cash flow, gross margin, revenue growth, and SG&A as a percentage of revenue, as well as individual goals specific to each executive's area of responsibility, such as M&A engagement, regional revenue growth, working capital management, and budget adherence. For 2025, based on the personal component and company component achievement, the executives earned a bonus at a level above the target level. For the fiscal year 2025, the target cash incentive bonus for each of Messrs. Hummer, Willems, and Morrison, respectively, were 125%, 90% and 80% of base salary.

Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company's share price from the beginning to the end of the measurement period by the Company's share price at the beginning of the measurement period.

(5)	Reflects the amount of net income or loss reported in the Company's audited financial statements for the applicable year.

The Company's compensation program for its named executive officers has been thoughtfully designed to support the Company's long-term business strategies and drive creation of stockholder value. The Company's annual cash incentive bonus was measured based on the generation of Adjusted EBITDA, a measure of profitability, for the year as well as a personal performance component, which depended on the executive's achievement of personal goals. The annual cash incentive bonus contained a minimum level requirement whereby if the minimum level is not met, there would be no annual cash incentive award earned for the Company component, and a maximum level cap of 200% of the target bonus. The Company's long-term incentive awards consist of restricted stock units, equivalent stock units and performance stock unit awards, which reward the named executive officers for financial returns, absolute stock price appreciation, and relative shareholder return performance. Performance stock units are tied to the Company's TSR relative to the TSR performance of the peer group over a specified period of three years.

As demonstrated by the following graph, the amount of compensation actually paid to Mr. Hummer is aligned with the Company's cumulative TSR over the three-year period presented. The average amount of compensation actually paid to the Company's NEOs as a group (excluding the Chief Executive Officer) is also positively correlated with the Company's cumulative TSR, though to a lesser degree. This alignment reflects the fact that a significant portion of the compensation actually paid to the NEOs is comprised of equity awards, where the value of the award is either directly based on absolute stock appreciation, in the case of restricted stock units and equivalent stock units, or relative shareholder return, in the case of performance stock units, that is less impacted by absolute Company TSR. However, this alignment is tempered because the change in fair value of performance stock unit awards is largely dependent on the relative shareholder return versus a peer group, which could mean that the value of the award increases even when Company TSR decreases.

As demonstrated by the following graph, the amount of compensation actually paid to Mr. Hummer, our Chief Executive Officer, and the average amount of compensation actually paid to the Company's NEOs as a group (excluding the Chief Executive Officer) is positively correlated with the Company's net income (loss) over the three years presented in the table. This correlation is driven in part by the annual cash incentive bonus, which is based on Adjusted EBITDA, a measure that is generally correlated with net income (loss). For 2025, based on the personal component and company component achievement, the executives earned a bonus at a level above the target level; for 2024, based on the personal component and company component achievement, the executives earned a bonus at a level above the target level; and for 2023, the Company did not meet the minimum level requirement, and thus no annual cash incentive award was earned by executives. However, as described above, compensation actually paid also depends on the change in value of the equity awards, where the value of the award is either more directly based on absolute stock appreciation, in the case of restricted stock units and equivalent stock units, or relative shareholder return, in the case of performance stock units.

Executive Officer and Director Stock Ownership Requirements

To further align the interests of our directors and executive officers with the long-term interests of stockholders, our Board has adopted Common Stock Ownership Guidelines ("Stock Ownership Guidelines") that require our executive officers and non-employee directors to own a specified amount of common stock shares, set at a multiple of the directors' base annual cash retainer or the officers' base annual salary, in each case, in effect as of March 31 of each applicable year. The ownership levels required under the Stock Ownership Guidelines are as follows:

Role		Multiple
Non-Employee Director		5x
Chief Executive Officer		5x
Chief Operations Officer		3x
Chief Financial Officer		3x
Executive Vice President, General Counsel		1.6x
Vice President, Controller		1.0x

All individuals covered by the Stock Ownership Guidelines are expected to reach the requisite level of target ownership within five years of March 1, 2018, if covered by the policy on such date, or within five years of becoming subject to the policy. In connection with any promotion, the individual will have five years from the date of promotion. Actual shares of stock, restricted stock units (including vested deferred stock units), and earned but unvested performance stock units are counted in satisfying the Stock Ownership Guidelines. Shares issuable upon exercise of unexercised stock options and unearned performance stock units are not counted. An officer who is not in compliance with the policy may only sell shares to pay the applicable taxes related to an award of restricted stock units or performance stock units, as applicable. Each of our directors and named executive officers subject to the requisite level of target ownership currently satisfies the stock ownership requirements set forth in the policy. Pursuant to the Stock Ownership Guidelines, if an executive or director has satisfied the policies' requirements on a prior determination date, the individual will be deemed to be in compliance for future determination dates as long as the individual owns at least as many securities eligible to be counted as the individual was required to own for compliance at the prior evaluation date when in compliance. Given the significant value of shares required to be held, we believe the policy is effective in aligning the interests of our directors and executive officers with those of our stockholders.

Director Compensation

Directors who are employed by us are not eligible to receive compensation for their service on our Board. All other members of our Board who are newly elected received a one-time stock option or restricted stock unit grant upon their election to the Board and all other members of our Board receive 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 2025, we paid our eligible directors a quarterly retention fee of $15,625. Such directors also received an annual award of restricted stock units in an amount of $125,000, which vests on approximately 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.

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 accommodation, meals and other incidental expenses for the directors. The compensation for our directors who were not employees for fiscal 2025 was as follows:

Name		Fees Earned or Paid in Cash ($)				Stock Awards ($)(1)(2)				Total ($)
Michael McShane			130,500				106,479				236,979
John Deane			80,500				106,479				186,979
Gurinder Grewal			62,500				106,479				168,979
W. Matt Ralls			62,500				106,479				168,979
Valerie Mitchell			62,500				106,479				168,979
Robert Nipper			62,500				106,479				168,979

(1)	Represents the aggregate grant date fair value for restricted stock units granted in 2025, determined in accordance with ASC 718. The grant date fair value of the restricted stock units granted to Messrs. McShane, Deane, Grewal, Ralls and Nipper and Ms. Mitchell was $24.54.

(2)

As of December 31, 2025, each director who was not an employee for fiscal 2025 had the following number of outstanding restricted stock units: Mr. McShane-4,339, Mr. Deane-4,339, Mr. Nipper-4,339, Mr. Ralls-25,256, of which 20,917 were fully vested, Ms. Mitchell-23,551, of which 19,212 were fully vested, and Mr. Grewal-17,698, of which 13,359 were fully vested.

Equity Incentive Plans

We maintain one equity incentive plan for the benefit of our employees, directors and other service providers. Previously, we maintained the 2012 Equity Incentive Plan, as amended and restated on each of February 6, 2015 and July 1, 2016 (the "2012 EIP"), which expired on December 20, 2022 and pursuant to which no further awards will be granted, with any outstanding awards issued thereunder remaining outstanding in accordance with the terms of the applicable award agreement. The Amended and Restated 2017 Equity Incentive Plan, effective as of May 21, 2025 (the "2017 EIP"), was initially adopted in connection with our initial public offering 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 was 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 were eligible to participate in the Employee Stock Purchase Plan applicable to their jurisdiction, subject to certain exceptions for employees who had 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 indefinitely suspended for offering periods beginning on or after July 1, 2019.
