PROXY STATEMENT - GENERAL MATTERS
This Proxy Statement is furnished to the stockholders of Arq, Inc., a Delaware corporation, ("Arq" or the "Company") in connection with the solicitation of proxies by the Company's Board of Directors (the "Board"), to be voted at our 2026 Annual Meeting of Stockholders (the "Annual Meeting" or "meeting") to be held virtually at 9:00 AM (Mountain Time) on Wednesday, June 10, 2026, via live webcast, and any postponements or adjournments thereof. This Proxy Statement and accompanying form of proxy are first being made available to our stockholders on or about April 28, 2026. The shares represented by all proxies that are properly executed and submitted will be voted at the meeting in accordance with the instructions indicated thereon, and if no instructions are given, then to the extent permitted by law, in the discretion of the proxy holder. Throughout this Proxy Statement, the terms "we," "us," "our" and "our Company" refer to Arq, Inc. and, unless the context indicates otherwise, our consolidated subsidiaries.
PARTICIPATION IN VIRTUAL MEETING
In accordance with Delaware law, the Board has authorized that the Annual Meeting be held virtually via webcast. Accordingly, stockholders and proxy holders virtually attending the Annual Meeting will be deemed present in person for purposes of determining the presence of a quorum.
We will furnish our proxy materials through a "notice and access" model via the internet in accordance with U.S. Securities and Exchange Commission ("SEC") rules. We are providing our "Notice of Internet Availability of Proxy Materials" to stockholders beginning on or about April 28, 2026. This document contains instructions on how you can access our proxy materials online. We are also mailing a full set of our proxy materials to stockholders who previously requested paper copies of the materials. In addition, instructions on how to request a printed copy of these materials may be found in our Notice of Internet Availability of Proxy Materials.
For stockholders of record, the only item of information needed to access the Annual Meeting from the website is the 16-digit control number located in the Notice of Internet Availability of Proxy Materials or on your proxy card. If your shares are held in street name (as explained below) and your voting instruction form or Notice of Internet Availability indicates that you may vote those shares through the http://www.proxyvote.com website, then you may access, participate in, and vote at the Annual Meeting with the 16-digit access code indicated on that voting instruction form or Notice of Internet Availability. Otherwise, stockholders who hold their shares in street name should contact their bank, broker or other nominee (preferably at least 5 days before the Annual Meeting) and obtain a "legal proxy" in order to be able to attend, participate in or vote at the Annual Meeting.
Questions posed by stockholders of record pertinent to Annual Meeting matters will be answered during the Annual Meeting, subject to time constraints. Questions regarding personal matters or material non-public information of the Company are not pertinent to Annual Meeting matters and will not be answered. Any questions pertinent to meeting matters that cannot be answered during the meeting due to time constraints will be answered on our website at ir.arq.com. The questions and answers will be available as soon as practical after the meeting and will remain available until one week after posting. If you encounter any technical difficulties with the virtual meeting platform on the day of the Annual Meeting, technical support phone numbers will be posted at the top of the virtual meeting log-in page. Technical support will be available starting at 6:00 a.m. Mountain Time on June 10, 2026, and will remain available after the meeting has finished.
Please have the Notice of Internet Availability of Proxy Materials or proxy card in hand when you access the website and then follow the instructions.
VOTING RIGHTS AND VOTE REQUIRED
Our Board has fixed the close of business on April 14, 2026 as the record date (the "Record Date") for determination of stockholders entitled to notice of and to vote at the meeting. On the Record Date, 42,876,258 shares of our common stock were issued and outstanding, each of which entitles the holder thereof to one vote on all matters that may come before the Annual Meeting.
We do not have any class of voting securities outstanding other than our common stock. A minimum of one-third of the shares of our common stock issued and outstanding entitled to vote at the Annual Meeting must be represented at the Annual Meeting in person or by proxy in order to constitute a quorum. An abstention or a "broker non-vote" (as explained below) will be counted as present for determining whether the quorum requirement is satisfied. If a
6

quorum exists, actions or matters other than the election of the Board are approved if the votes cast in favor of the action exceed the votes cast opposing the action unless a greater number is required by the Delaware General Corporation Law or our Second Amended and Restated Certificate of Incorporation. In accordance with our bylaws, our Board designated any uncontested election of directors, including election of directors at this Annual Meeting, as a proposal to be subject to the plurality voting standard. As such, the six nominees receiving the highest number of votes cast will be elected as directors. Cumulative voting is not allowed for any purpose.
If, as of the Record Date your shares were held in an account at a brokerage firm, bank, dealer, or other similar organization, then that firm or organization is the stockholder of record for purposes of voting at the Annual Meeting and you are considered the beneficial owner of shares held in "street name." If you are a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares held in your account. If you do not instruct your broker or other agent on how to vote your shares, your broker or other agent, in its discretion, may vote your shares on routine matters or they may elect not to vote your shares. Whether or not a matter is routine is subject to the determination by the stock exchange. When a broker or other agent holding shares for a beneficial holder does not receive voting instructions from the beneficial owner and the broker or other agent does not have discretionary voting power on the matter(s), it will result in a "broker non-vote" for the matters on which the broker or other agent cannot vote. Broker non-votes on a particular proposal are considered present for purposes of determining a quorum, but will not be treated as votes cast with respect to any proposal.
Abstentions and "broker non-votes" will have no effect on the outcome of proposals voted upon at the Annual Meeting, except we do not expect there to be any "broker non-votes" for purposes of the ratification of our independent registered public accounting firm, as broker or other agents are expected to have discretionary authority to vote on this proposal (although they are not required to do so).
Unless instructions to the contrary are marked, or if the proxy card is properly executed but no instructions are specified, shares represented by proxies will be voted as follows:
FOR ALL the persons nominated by the Board for Directors for election at the Annual Meeting, being: Laurie Bergman, Jeremy Blank, Richard Campbell-Breeden, Carol Eicher, Julian McIntyre, and Robert Rasmus;
FOR the approval, on an advisory basis, of the compensation of the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including compensation tables and narrative discussion as set forth under the Executive Compensation section of this Proxy Statement;
FOR the ratification of the appointment of Baker Tilly US, LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026;
FOR the approval of the Arq, Inc. 2026 Omnibus Incentive Plan; and
FOR the approval of the Ninth Amendment to the Company's Tax Asset Protection Plan.
We do not know of any other matter or motion to be presented at the Annual Meeting. If any other matter or motion should be presented at the Annual Meeting upon which a vote must be properly taken, to the extent permitted by law, the persons named in the accompanying form of proxy intend to vote such proxy in the discretion of such person as the directors of the Company may recommend, including any matter or motion dealing with the conduct of the Annual Meeting.
Voting by Mail, via the Internet or by Telephone
Stockholders whose shares are registered in their own names may vote by mailing a completed proxy card, via the internet or by telephone. Instructions for voting via the internet or by telephone are set forth on the included proxy card. If this Proxy Statement was mailed to you or if you requested that a proxy statement be mailed to you, you may vote your shares by mail. To vote by mailing a proxy card, sign and return the available proxy card to the address set forth on the proxy card and your shares will be voted at the Annual Meeting in the manner you direct. If no directions are specified but the proxy card is properly executed, your shares will be voted as described above.
If your shares are registered in the name of a bank or brokerage firm, you may be eligible to vote your shares over the internet or by telephone rather than by mailing a completed voting instructions card provided by the bank or brokerage firm. Please check the voting instructions card provided by your bank or brokerage firm for availability
7

and instructions. If internet or telephone voting is unavailable from your bank or brokerage firm, please complete and return the voting instructions card provided by the bank or brokerage firm.
Any stockholder who completes a proxy card or votes via the internet or by telephone may revoke the action at any time before it is exercised at the Annual Meeting by delivering written notice of such revocation to the Company's General Counsel and Secretary, 8051 E. Maplewood Ave., Ste. 210, Greenwood Village, Colorado 80111, by submitting a new proxy card executed at a later date, or by joining the virtual meeting and voting such stockholder's shares in a manner different to his, her, or its previously completed proxy card.
The Company is bearing the costs of this solicitation of proxies. In addition to the mailing of these proxy materials, the solicitation of proxies or votes may be made in person, by telephone, or by electronic communication by certain of our directors, officers, and employees, who will not receive any additional compensation for such solicitation activities.

PROPOSAL ONE
ELECTION OF DIRECTORS OF THE COMPANY
The Nominating and Governance Committee has recommended to our Board the slate of six directors—Laurie Bergman, Jeremy Blank, Richard Campbell-Breeden, Carol Eicher, Julian McIntyre, and Robert Rasmus—for election by our stockholders, and the Board approved the recommendation and the slate of directors.

Director Independence
Currently our Board consists of four independent directors, as defined under the applicable Nasdaq listing standards (Laurie Bergman, Richard Campbell-Breeden, Carol Eicher, and Julian McIntyre).

The Board considered Mr. McIntyre's prior employment with Arq Limited, which terminated upon him becoming a director of the Company and determined that it would not impair Mr. McIntyre's independence under the applicable SEC and Nasdaq rules.
The Board maintains Audit, Compensation, and Nominating and Governance Committees, each of which was at all times during 2025, is currently comprised of, and will continue to be comprised as of the Annual Meeting and thereafter solely of independent directors under applicable independence standards of the Nasdaq listing rules. Promptly upon completion of the Annual Meeting, the Board expects to set committee membership and appoint committee chairs for the ensuing year.
Board and Committee Meetings and Attendance at Meeting of Stockholders
The Board currently has three committees: the Audit Committee, the Compensation Committee, the Nominating and Governance Committee.
The Board met six times in 2025. The Audit Committee met four times in 2025. The Compensation Committee met four times in 2025. The Nominating and Governance Committee met seven times in 2025. All of the incumbent directors attended at least 75% of the meetings of the Board and the committees of which they were members during 2025.
Directors are expected to attend all Board and respective committee meetings. In addition, directors are expected to make their best efforts to attend the Company's annual meetings of stockholders either in person or telephonically. Five out of six of our current directors attended last year's annual meeting of stockholders.
Stockholder Communications to Directors
Any stockholder or any other interested party may communicate directly with the Board (or any individual director or Chair of the Board) by writing to the Chair of the Board, Arq, Inc., 8051 E. Maplewood Ave., Ste. 210 Greenwood Village, Colorado 80111 or by emailing the Board through the "Contact" page on our website at www.arq.com. Any such communication should state the number of shares owned of record or beneficially owned by the stockholder making the communication. Provided that such communication addresses a legitimate business issue, the Company or the Chair will forward the stockholder's communication to the appropriate director. For any communication relating to accounting, auditing or fraud, such communication will be promptly forwarded to the Chair of the Audit Committee.
Code of Ethics
We have adopted a Code of Ethics and Business Conduct that includes a code of ethics as defined in Item 406(b) of SEC Regulation S-K. Our Code of Ethics and Business Conduct incorporates our Insider Trading Policy, Anti-Bribery & Anti-Corruption Policy, Anti-Money Laundering Policy and Regulation FD Policy, each of which applies to our officers, directors, and employees, including the principal executive officer, principal financial officer, principal accounting officer or controller or other persons performing similar functions. A copy of our Code of Ethics and Business Conduct is available on our investor relations website at ir.arq.com. We intend to disclose any amendments to our Code of Ethics and Business Conduct, or waivers of such provisions granted to executive officers and directors, on our website in accordance with, and to the extent required by, the SEC and Nasdaq rules. Please note that the information on our website is not part of this Proxy Statement and is not incorporated by reference herein.
Board Leadership Structure and Role in Risk Oversight
We have a policy of keeping the roles of Chief Executive Officer ("CEO") and Chair of the Board separate, and the roles are currently filled by two different individuals. We believe this arrangement is appropriate as it recognizes the distinction between the role played by the CEO, whose position is more heavily oriented towards day-to-day management, and the Chair, whose role as an independent director is to oversee the Board and participate in and chair executive sessions of the Board.
14

Our Board is responsible for establishing broad corporate policies and monitoring the overall performance of the Company. However, in accordance with corporate legal principles, the Board is not involved in day-to-day operating matters. Members of the Board are kept informed of the Company's business by participating in Board and committee meetings, by reviewing analysis and reports sent to them periodically and monthly, and through discussions with the CEO and other officers.
Our Board receives quarterly updates from our CEO and other members of executive management regarding enterprise risks, including operation, cybersecurity, financial, legal and regulatory and strategic. These risks are evaluated on a short-, intermediate- and long-term basis. Management has a systematic and integrated approach to overall risk management that includes the identification of risks and mitigation plans.
The Board has designated the Audit Committee to oversee risk management, including cybersecurity and overall controls (including anti-fraud and Sarbanes-Oxley Act of 2002 (SOX) controls), and the Audit Committee periodically reports to the Board regarding briefings provided by management and advisors, as well as its own analysis and conclusions regarding the adequacy of the Company's risk management processes. In addition to this compliance program, the Board encourages management to promote, and management is committed to promoting, a corporate culture that incorporates risk management into the Company's strategy and day-to-day business operations. The Board and management continually work together to assess and analyze our most likely areas of risk.
Audit Committee
Our Board has appointed an Audit Committee currently consisting of Mses. Bergman and Eicher, and Mr. Campbell-Breeden. Ms. Bergman currently serves as the Chair of the Audit Committee.
Our Board determined that Mses. Bergman and Eicher and Mr. Campbell-Breeden are each an "audit committee financial expert." Each Audit Committee member is "independent" under the applicable independence standards of the SEC and Nasdaq Stock Market, including heightened independence standards applicable to audit committee members, and a brief listing of their relevant experience is stated in each of their biographies above.
The role and functions of the Audit Committee are set out in the Audit Committee Charter. The role of the Audit Committee is one of oversight of the services performed by the Company's independent registered public accounting firm. The Audit Committee's functions include the following:
▪Reviewing and assessing the Audit Committee Charter annually;
▪Overseeing the Company's compliance with legal and regulatory requirements, including the Code of Ethics and Business Conduct and approving related party transactions;
▪Overseeing the Company's processes to identify and manage business and financial risk;
▪Reviewing the Company’s compliance with cybersecurity laws and regulations and overseeing the Company’s cybersecurity policies, procedures, and programs;
▪Appointing, approving the compensation of, and reviewing the Company's relationships with, its independent registered public accounting firm and/or other auditors and assessing the impact such relationships may have on the auditors' objectivity and independence;
▪Taking other appropriate action to evaluate the independence of the Company’s independent registered public accounting firm;
▪Reviewing and considering the matters identified in Public Company Accounting Oversight Board ("PCAOB") professional auditing standards with the Company’s independent registered public accounting firm and management;
▪Reviewing and discussing the Company's financial statements and report on internal control with the Company’s independent registered public accounting firm;
▪Reviewing the financial reporting process and discussing with management and our independent registered public accounting firm the interim and annual financial statements that we file with the SEC; and
15

▪Reporting to the Board on all such matters. In performing its oversight function, the Audit Committee relies upon advice and information received in its discussions with the Company’s management and independent registered public accounting firm.
The Audit Committee pre-approves all audit or non-audit services performed by our independent registered public accounting firm in accordance with Audit Committee policy and applicable law.
The Audit Committee has a written charter, a copy of which is available on our investor relations website at ir.arq.com under the "Corporate Governance Docs" section of "Corporate Governance." Please note that the information on our website is not part of this Proxy Statement and is not incorporated by reference herein.
Audit Committee Oversight of Cybersecurity
The Board oversees management’s processes for identifying and mitigating risks, including cybersecurity risks. The Audit Committee maintains delegated oversight of cybersecurity risks, bringing in third-party service providers as needed to advise on cybersecurity infrastructure, policies, risk assessment processes and practices. Our Vice President of Information Technology ("VP of IT") primarily oversees these third-party service providers who assist in monitoring and testing our safeguards, including execution of external penetration testing and ongoing real time vulnerability assessments through our extended detection and response processes to identify cybersecurity threats. Our VP of IT briefs the Audit Committee quarterly, at a minimum, on our cybersecurity risks, business-impacting incidents, and ongoing and future cybersecurity project implementations. The full Board receives regular updates from the Audit Committee and, as needed, from our VP of IT, regarding its oversight of cybersecurity risks and our cybersecurity risk management program.
For additional information regarding our cybersecurity management, please refer to our Annual Report on Form 10-K for the year ended December 31, 2025, under Item 1C. Cybersecurity.
Compensation Committee
Our Board has appointed a Compensation Committee currently consisting of Mr. Campbell-Breeden and Mses. Bergman and Eicher. Mr. Campbell-Breeden currently serves as the Chair of the Compensation Committee.
The responsibilities of the Compensation Committee, as set forth in the Compensation Committee Charter, include reviewing our executive compensation programs to analyze their alignment with attracting, retaining and motivating our executive officers to achieve our business objectives; establishing annual and long-term performance goals for our executive officers and evaluating their performance in light of such goals; reviewing, approving and, when appropriate, making recommendations concerning our long-term incentive plans; reviewing and making recommendations regarding stockholder proposals related to compensation; and administering our equity-based and employee benefit plans.
Each year, the Compensation Committee reviews, modifies (if necessary), and approves the goals and objectives relevant to the compensation of our CEO and other named executive officers, as well as the executive compensation program as a whole, including performance goals for the annual cash incentive program, if applicable, and long-term equity awards. In addition, the Compensation Committee is responsible for reviewing the performance of our CEO within the framework of our executive compensation goals and objectives. Based on this evaluation, the Compensation Committee sets the compensation of the CEO. See "Executive Compensation" below for additional information.
The Compensation Committee has a written charter, a copy of which is available on our investor relations website at ir.arq.com under the "Corporate Governance Docs" section of "Corporate Governance."

Nominating and Governance Committee
Our Board has appointed a Nominating and Governance Committee currently consisting of Mses. Eicher and Bergman, and Mr. Campbell-Breeden. Ms. Eicher currently serves as the Chair of the Nominating and Governance Committee.
The responsibilities of the Nominating and Governance Committee include:
16

▪Reviewing and recommending to the Board the size and composition of the Board;
▪Identifying and recommending director nominees for election to the Board;
▪Reviewing non-management director compensation;
▪Submitting non-management director compensation recommendations to the entire Board for approval;

Director nominees are generally identified by our directors, stockholders, officers or third party search firm based on industry and business contacts. Regardless of the source of the nomination, nominees are evaluated by the Nominating and Governance Committee, other members of the management team and the Board, as deemed appropriate by the Nominating and Governance Committee. The Nominating and Governance Committee then presents qualified candidates to the Board for a final discussion and vote.
We do not have a formal policy with respect to the consideration of diversity in the identification of director nominees, but the Nominating and Governance Committee strives to select candidates for nomination to the Board with a variety of backgrounds and complementary skills so that, as a group, the Board possesses the appropriate talent, skills, perspectives and expertise to oversee the Company's businesses. The Board assesses its effectiveness in this regard as part of the annual board and director evaluation process.
Under the Nominating and Governance Committee Charter, the Nominating and Governance Committee will consider nominees submitted by our stockholders. Recommendations of individuals that meet the criteria set forth in the Nominating and Governance Committee Charter for election at our 2027 annual meeting of stockholders may be submitted to the Nominating and Governance Committee in care of Clay Smith, General Counsel and Secretary, at 8051 E. Maplewood Ave., Ste. 210, Greenwood Village, Colorado 80111 no earlier than January 11, 2027 and no later than February 10, 2027. The Nominating and Governance Committee evaluates nominees recommended by stockholders using substantially the same criteria it uses to evaluate all other candidates.
The Nominating and Governance Committee has a written charter, a copy of which is available on our investor relations website at ir.arq.com under the "Corporate Governance Docs" section of "Corporate Governance."

Health, Safety and Sustainability at Arq
At Arq, we believe that a robust approach to health, safety and sustainability is an important element of long-term success and an enabler of better Company performance. We create and commercialize innovative technical solutions that drive our mission to improve the quality of the air we breathe, water we drink and soil our children play on—our products play a pivotal role in removing numerous harmful pollutants (such as per- and polyfluoroalkyl substances ("PFAS") and mercury) from water supplies, contaminated land sites, and air emissions. We believe that our mission is underpinned by sound governance, effective stewardship of resources, and awareness of the social issues affecting our employees and the communities in which we operate.
Our Board and our Nominating and Governance Committee each oversee certain aspects of our health, safety and sustainability programs. While our management team manages the day-to-day operation of our programs, our Board
17

is responsible for health and safety oversight and our Nominating and Governance Committee is responsible for sustainability oversight, including overall performance and objectives.
Our Board monitors the performance and sets out overarching goals of our health and safety programs, assesses health and safety risks relevant to Arq and receives at least quarterly updates from our management team regarding health and safety metrics across our facilities.
The Nominating and Governance Committee monitors the evolving sustainability opportunities and risks most relevant to Arq in addition to oversight of our sustainability policies and annual disclosures. Our Nominating and Governance Committee receives at least quarterly updates from our management team. Additionally, the Nominating and Governance Committee makes recommendations to our Board regarding sustainability-related commitments and reviews and approves our annual Sustainability Report ("Sustainability Report").
Health and Safety
Health and safety is a core value of the Company and our employees’ health and safety is critical to our ongoing success. In order to ensure that we are aware of, and proactively mitigate, any health and safety risks, we maintain a health and safety ("HS") team that is responsible for ensuring we have a robust range of policies, systems and emergency action plans in place for each of our facilities. The HS team compiles monthly safety reports and quarterly briefs on key compliance indicators that are shared with and reviewed by our management team. Our Board, who is ultimately responsible for health and safety oversight, then receives an update from our management team on these key compliance indicators at least on a quarterly basis.
Our approach to health and safety is underpinned by compliance with the regulations of the Occupational Safety and Health Administration ("OSHA") and the Mine Safety and Health Administration ("MSH"), as applicable across our facilities. We have an established health and safety management system, incorporating best practices and compliance with relevant and applicable OSHA and MSHA requirements. This approach includes our program of health and safety training, which is mandatory for all employees alongside additional job- and location-specific training for relevant employees. These trainings and programs empower our employees to be collectively responsible for everyone’s safety. We track a range of leading health and safety indicators, including near misses, hazard recognitions, and training completion. We also have a comprehensive process for conducting a root cause analysis for all incidents and near misses.
Further information pertaining to the health and safety of our employees and the communities in which we operate can be found in our annual Sustainability Report described below.
Sustainability
Throughout our history, Arq has enabled our customers and partners to meet and exceed their environmental goals. Alongside delivering innovative solutions to remove PFAS and other harmful chemicals and pollutants from water, land, and air; we continue to develop new products to allow for expansion into new markets and continue to explore the potential of our unique process of repurposing coal waste to create environmentally beneficial feedstocks and products.
Beyond the products we offer, sustainability also plays an important role in how we manage our business—we believe in the importance of continuously assessing and reducing our own environmental impact. In September 2025, we published our annual Sustainability Report, which includes detailed information on our product quality and safety, energy use, water and waste management, and greenhouse gas emissions, along with other sustainability disclosures and metrics. Our annual Sustainability Report, which covers our activities for the fiscal year ended December 31, 2024, is available at www.arq.com/sustainability/. We expect to publish our 2025 Sustainability Report, which will cover our activities for the fiscal year ended December 31, 2025, during the summer of 2026.

RELATED PERSON TRANSACTIONS
The charter of our Audit Committee requires all related person transactions to be reviewed and approved by the Audit Committee. A related person transaction is, defined as any transaction, arrangement, or relationship (including any indebtedness or guarantee of indebtedness), or any series of similar transactions, arrangements, or relationships, in which (a) the aggregate amount involved will or may be expected to exceed $120,000, (b) the Company is a participant, and (c) any Related Person has or will have a direct or indirect material interest (other than solely as a result of being a director or trustee (or any similar position) or a less than 10 percent beneficial owner of another entity). A "Related Person" is any (a) person who is an executive officer, director, or nominee for election as a director of the Company, (b) greater than five percent beneficial owner of our outstanding common stock, or (c) Immediate Family Member of any of the foregoing. An "Immediate Family Member" is any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, and any person (other than a tenant or employee) sharing the household of the persons listed above. We do not have written policies or procedures for related person transactions but rely on the Audit Committee’s exercise of business judgment, consistent with Delaware law, in reviewing such transactions.
During our fiscal year ended December 31, 2025, there were no related person transactions that require disclosure under Item 404 of Regulations S-K.

PROPOSAL TWO
APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION PAID TO COMPANY'S NAMED EXECUTIVE OFFICERS
Pursuant to Section 14A of the Exchange Act, we are seeking a non-binding advisory vote to approve the compensation of our named executive officers ("NEOs") as disclosed in the section of this Proxy Statement titled "Executive Compensation." Although this vote is advisory and is not binding on the Company, the Compensation Committee will take into account the outcome of the vote when considering future executive compensation decisions. We believe that our compensation philosophy and practices are consistent with market practices, designed to retain key executives and reward Company performance, and aligned with long-term stockholder interests. This proposal will be deemed approved, on a non-binding advisory basis, if the votes cast in favor of the proposal exceed the votes cast opposing the proposal.
The Board proposes the following resolution for approval by the stockholders:
RESOLVED, that the stockholders approve the compensation of the Company's named executive officers as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission (which includes the compensation tables and related narrative discussion).
The Board currently has a policy of holding advisory votes to approve executive compensation every year. Our stockholders last approved the frequency of advisory votes on executive compensation at our 2025 annual meeting of stockholders. Our stockholders will again be asked to vote on the frequency of future advisory votes on executive compensation during the 2031 annual meeting of stockholders.
Board Recommendation
Our Board recommends a vote "FOR" the proposal to approve, on an advisory basis, the Company's compensation paid to our NEOs.

Summary Compensation Table
The following table presents information regarding compensation earned by or awards to our NEOs during fiscal years 2025 and 2024:

Name and Principal Position |  | Year |  | Salary ($) |  | Bonus ($) (1) |  | Stock Awards ($) (2) |  |  |  | Non-Equity Incentive Plan Compensation ($) (3) |  | All Other Compensation ($) (4) |  | Total ($)

(1)Because the Short-Term Incentive Plan (the "STIP") has mandatory performance measures that must be achieved before there is any payout to NEOs, amounts paid under the STIP are shown in the Non-Equity Incentive Plan Compensation column of the table, rather than the Bonus column. Bonus amounts earned and paid in 2025 consisted of awards granted in connection with certain commissioning milestones at the Company’s granular activated carbon facility.
(2)The amounts in this column represent the aggregate grant date fair values of restricted stock awards ("RSAs") and performance share units ("PSUs") computed in accordance with FASB ASC Topic 718. These grant date fair values have been determined based on the assumptions and methodologies discussed in Note 11 of the Consolidated Financial Statements included in our
27

Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The PSU awards to Mr. Rasmus, Mr. Smith, and Mr. Williamson are subject to market-based performance conditions relating to the relative placement of the Company’s total shareholder return ("TSR") for the three-year performance period as compared to the respective TSRs of a specified group of peer companies. The table below presents the market based PSU awards granted for the fiscal year ended December 31, 2025 based on an earned percentage of 100% (grant date fair value disclosed above) and an earned percentage of 200%, which is the highest level of performance conditions that can be achieved. The difference between the "Stock Award" amounts in the table above and the "PSU-if earned, target ($)" amounts in the table below represents the grant date fair values attributable to the RSAs and other awards included at potential maximum payout. Pursuant to the terms of Mr. Williamson’s separation agreement (the “Williamson Separation Agreement”), the value of any unvested PSUs shall be determined by calculating the Company’s TSR against that of the Company’s Peer Group (as defined below) and if greater than zero, shall be paid out in shares of the Company’s common stock within sixty days of the date of the Williamson Separation Agreement.

Name |  |  |  | PSU - if earned, target ($) |  | PSU - if earned, maximum ($)
Robert Rasmus |  |  |  | 37,125 |  |  | 74,250 |
Clay Smith |  |  |  | 178,203 |  |  | 356,406 |
Jeremy Williamson |  |  |  | 208,833 |  |  | 417,666 |

(3)The amounts in this column represent the bonuses earned for the applicable year under the STIP.
(4)The All Other Compensation amounts for each NEO for 2025 are made up of the amounts in the table below:

Name |  |  |  | Matching contributions to 401(k) ($) |  |  |  | Other ($) |  | Total ($)
Clay Smith |  |  |  | 9,385 |  |  |  |  | — |  |  | 9,385 |

Narrative Disclosure to Summary Compensation Table
Overview of Executive Compensation Program
Our Compensation Committee is charged with establishing the Company’s philosophy for executive compensation and the approval, oversight, implementation and administration of executive compensation and benefits. Generally, the Chief Executive Officer of the Company makes recommendations to the Compensation Committee regarding executive compensation other than for himself; however, authority to approve compensation, performance goals and objectives for all NEOs is vested in the Compensation Committee.
Our philosophy for executive compensation is set forth in a document entitled "Executive Compensation Philosophy and Objectives" (the "EC Philosophy") reviewed annually by the Compensation Committee to ensure the EC Philosophy remains appropriate. The EC Philosophy is designed to support achievement of our strategies and goals, thereby creating long-term value for our stockholders and customers and ensuring our ability to recruit and retain highly qualified executive employees. Our EC Philosophy is designed to:
▪Support the Company’s vision, mission, strategy, and values to generate profitability and sustained growth in the long-term best interests of our stockholders;
▪Align executive compensation with measures of performance tied to the strategic and operational performance of the business and stockholder returns;
▪Reward executives on the basis of merit for individually and collectively achieving a leadership culture, innovation and excellence within the Company, and delivering sustained high performance to the Company, taking into consideration each executive’s qualifications, level of responsibility and contribution to the Company’s long-term performance;
▪Encourage competency-building by linking career development, performance management and compensation rewards;
▪Attract and retain the best executive talent and a highly qualified workforce within a non-discriminatory, merit-based compensation program; and
▪Use external compensation data from sources where the Company competes for talent as one key factor in
28

establishing the market competitiveness of our compensation program.
We believe that our compensation policies and practices do not motivate excessive or imprudent risk-taking. We note the following key aspects of our compensation policies and practices in making this determination:
▪The Company’s EC Philosophy is based on balanced performance metrics that promote disciplined progress towards long-term Company goals in addition to the short-term health of the organization;
▪We do not offer significant short-term incentives that might drive high-risk investments at the expense of long-term Company value; and
▪The Company’s compensation programs are weighted towards long-term incentives.
Because of these factors, we believe that our compensation policies and practices, both for our employees and our executive officers, do not create risks that are reasonably likely to have a material adverse effect on the Company.
Say-on-Pay
The Company provides its stockholders with the opportunity to cast an advisory vote on annual executive compensation (a "say-on-pay proposal"). At the Company’s 2025 annual meeting of stockholders, approximately 97% of the votes cast were in favor of the say-on-pay proposal, which the Compensation Committee reviewed in assessing executive compensation for the fiscal year ending December 31, 2025. Proposal 2 included in the Proxy Statement is a say-on-pay advisory vote regarding the executive compensation for the fiscal year ending December 31, 2025 as described in this Proxy Statement. The Compensation Committee will continue to consider the results of the Company's say-on-pay votes when making future compensation decisions for the Company's executive officers, including the NEOs.
Independent Compensation Consultant and Peer Group
In making decisions with respect to 2025 compensation, the Compensation Committee utilized a peer group that was established in late 2024 as a result of market analysis undertaken by Alvarez & Marsal, LLC in connection with their engagement as the Compensation Committee’s independent compensation consultant. The Compensation Committee reviewed these peer companies in late 2024 and approved their use for compensation benchmarking purposes (the "Peer Group"). In setting executive compensation for 2025, the Compensation Committee compared the compensation practices of the Company to the 15 Peer Group companies, set forth in the table below, from a number of similar industries, including Chemicals, Commercial Services and Supplies, Machinery, Oil, Gas and Consumable Fuels, and Energy Equipment and Services.

Aemetis, Inc. |  | Graham Corporation
American Vanguard Corporation |  | LanzaTech Global, Inc.
Aris Water Solutions, Inc. |  | OPAL Fuels Inc.
Clean Energy Fuels Corp. |  | Origin Materials, Inc.
Energy Recovery, Inc. |  | Perma-Fix Environmental Services, Inc.
Flotek Industries, Inc. |  | Profire Energy, Inc.
FutureFuel Corp. |  | Taylor Devices, Inc.
Gevo, Inc. |  |

Base Salary
Base salary is defined as ongoing cash compensation, paid bi-weekly, and determined by factors such as job responsibilities, external market competitiveness, and an individual’s experience and performance. Compensation is aligned with the market where the Company competes for similar roles, considering employees in comparable companies. Using market and Peer Group data, the Compensation Committee evaluates base salary adjustments based on industry benchmarks, Company performance, and the achievement of pre-determined objectives. The Company aims to provide mid-market pay for strong performers, with the potential for higher compensation for exceptional contributors. However, the Company does not seek to be a market leader in base salary.
29

Short-Term Incentive Plan
The STIP is designed to enhance the value of the Company by providing incentives for the achievement of one or more performance goals selected by the Compensation Committee for the applicable performance period; to attract, motivate, and retain highly qualified employees; and to provide consistency with the Company’s approach to performance based pay. Incentives may be paid in cash or equity as determined by the Compensation Committee. The Compensation Committee made STIP awards under the 2017 Omnibus Incentive Plan (the "2017 Plan") through June of 2022, while STIP awards granted for 2023 were made under the 2022 Omnibus Incentive Plan (the "2022 Plan"). In 2024, the Company’s stockholders approved the adoption of the 2024 Omnibus Incentive Plan (the "2024 Plan"), which governs incentives awarded under the STIP for 2025. At the Annual Meeting the Company’s stockholders will be asked to approve the Company’s proposed 2026 Omnibus Incentive Plan. See "Proposal Four - Approval of Arq, Inc. 2026 Omnibus Incentive Plan" below for additional information.
In February 2025, the Compensation Committee approved STIP target opportunities of 55% of base salary for Mr. Smith and of 70% for Mr. Williamson. The Compensation Committee approved a STIP target of 100% of base salary for Mr. Rasmus.
The Compensation Committee also established STIP performance metrics for the 2025 performance period, which included earnings before interest, depreciation, and amortization (EBITDA), gross margin, selling, general and administrative (SG&A) expense as a percentage of revenue, overall equipment efficiency, and total recordable incident rate (TRIR).
In early 2026, based on the Company’s performance against the applicable metrics, the Compensation Committee determined that approximately 12.72% of the STIP performance targets had been achieved. In light of this level of performance, the Compensation Committee did not approve STIP payouts to the NEOs for 2025.
Long-Term Incentive Compensation
The Long-Term Incentive Plan ("LTIP") is designed to align executives’ interests with those of the Company’s stockholders and to support the Compensation Committee's approach to performance-based pay. Equity awards are the primary long-term incentive instrument and have historically been granted in the form of RSAs and PSUs. Equity awards vest over time based on continuous service, or over time based on achievement of certain performance measures set by the Compensation Committee at the time of the grant. Awards under the LTIP for 2025 were made 50% as RSAs and 50% as PSUs. PSUs vest upon the achievement of one or more performance measures, as determined by the Compensation Committee, following a three-year cliff vesting period.
LTIP awards were made under the 2017 Plan through June 2022 and were made under 2022 Plan from June 2022 to June 2024. All LTIP awards have been made under the 2024 Plan since its adoption in June 2024.
On February 12, 2025, the Compensation Committee approved grants of RSAs ("2025 RSAs") and PSUs ("2025 PSUs") to the NEOs, as detailed in the table below, with an effective date of March 23, 2025. The 2025 RSAs vest in equal one-third increments on March 23, 2026, March 23, 2027, and March 23, 2028, subject to each NEO’s continuous service with the Company. The 2025 PSUs vest after three years, based on the Company’s TSR ranking for the three-year performance period ending December 31, 2027, relative to our designated Peer Group.

Named Executive Officer |  | Percentage of Base Salary |  | Number of Restricted Shares |  | Target Number of Performance Stock Units
Robert Rasmus |  | 75% |  | 4,990 |  | 4,990
Clay Smith |  | 75% |  | 23,952 |  | 23,952
Jeremy Williamson |  | 75% |  | 28,069 |  | 28,069

The Compensation Committee uses our designated Peer Group to benchmark the Company's stock price performance for the 2025 PSUs. TSR is calculated for both the Company and its Peer Group companies. The threshold, target, and maximum payout percentages for the 2025 PSUs are as follows: Threshold: 50% payout at 30th percentile TSR rank; Target: 100% payout at 50th percentile TSR rank; Above Target: 125% payout at 65th percentile TSR rank; Maximum: 200% payout at 90th percentile TSR rank or higher.
30

PSUs granted in 2023 ("2023 PSUs") vested on February 27, 2026, following a three-year performance period ending December 31, 2025. The Company’s TSR performance for the 2023 PSUs ranked at approximately the 68th percentile within the peer group that was used at the time of the grant, resulting in a vesting percentage of 133.29% for these awards.
Policies And Practices Related To The Grant Of Certain Equity Awards Close In Time To The Release Of Material Nonpublic Information
Since 2016, the Compensation Committee has not granted stock options or similar awards as part of our equity compensation programs outside of one-time inducement grants made to Mr. Rasmus in connection with his hire. We do not grant stock options or similar awards in anticipation of the release of material nonpublic information that is likely to result in changes to the price of our common stock, such as a significant positive or negative earnings announcement, or time the public release of such information based on stock option grant dates. We do not grant stock options or similar awards during periods in which there is material nonpublic information about our Company, including (i) during “blackout” periods or outside a "trading window" established in connection with the public release of earnings information under our Insider Trading Policy. These restrictions do not apply to RSAs, PSUs or other types of equity awards that do not include an exercise price related to the market price of our common stock on the date of grant.
Our executive officers would not be permitted to choose the grant date for any stock option grants.
During 2025 and through the date of this Proxy Statement, we have not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation.

Further, upon a termination as a result of the NEO’s death or disability, the NEO (or the NEO’s beneficiary, as applicable) is eligible to receive (i) the short-term incentive cash bonus for the year of termination assuming target performance (or 50% thereof if such termination occurs within the first six months of the year), (ii) accelerated vesting of all unvested restricted stock awards, and (iii) accelerated vesting of all unvested performance share units based on actual performance as of the date of such termination.
Under the Smith and Williamson Agreements:
▪"Cause" means (i) the failure by an executive to substantially perform the essential functions of executive’s duties or obligations in a satisfactory manner or material breach of any written agreement with us or an affiliate; (ii) dishonesty, willful misconduct, or material breach of our Code of Ethics and Business Conduct,

▪"Good Reason" and "Change in Control" generally have the meaning described above under the Rasmus Agreement.
Williamson Separation Agreement
On March 4, 2026, the Company eliminated the position of Chief Operating Officer, and Mr. Williamson ceased serving in that role effective as that date. Mr. Williamson’s employment with the Company terminated on April 18, 2026. On April 22, 2026, the Company and Mr. Williamson entered into the Williamson Separation Agreement. Pursuant to the terms of the Mr. Williamson is entitled to (i) 12 months of base salary, (ii) accelerated vesting of all unvested RSAs, (iii) accelerated vesting of all unvested PSUs based on TSR as compared to the Peer Group as of the date of such termination, and (iv) coverage of COBRA continuation premiums for 12 months (or until Mr. Williamson is eligible for medical insurance benefits from another employer). In accordance with applicable law, the Williamson Separation Agreement contains a seven-day revocation period during which Mr. Williamson may revoke his signature. Receipt of the payments and benefits described above is subject to Mr. Williamson’s non-revocation of the Williamson Separation Agreement, which includes a customary release of claims.
Retirement Benefits
The Company’s Profit Sharing Retirement Plan ("401(k) Plan") is available to all eligible employees, including NEOs. Pursuant to the 401(k) Plan, we currently match the NEO’s contribution 100% up to three percent, and 50% on the next two percent, subject to income limitations based on IRS guidelines. Additionally, at the discretion of the Board, the Company may make contributions based on the profitability of the Company to those accounts. In 2025, the Company made contributions to each eligible employee’s account in accordance with the contribution schedule presented above. The Company made its contributions to the 401(k) Plan in cash. No discretionary contributions were made to the 401(k) Plan in 2025 other than as discussed above. Employee and Company contributions to the 401(k) Plan are 100% vested.
Company Policies Relating to Executive Compensation
Insider Trading Policy
Our Insider Trading Policy, which applies to our employees, officers and directors, prohibits hedging of our securities and engaging in any other transactions involving Arq based derivative securities, regardless of whether the covered person is in possession of material, non-public information (except with regard to the vesting of securities acquired pursuant to our incentive plans), or other transactions involving purchases and sales of company securities between a covered person and us. The Insider Trading Policy also prohibits all employees, officers and directors from entering into any transaction relating to hedging Arq securities, including zero-cost collars or forward-sale transactions. We believe that our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the listing standards applicable to the Company.
Equity Ownership Guidelines
The Company maintains Executive Stock Ownership Guidelines under the EC Philosophy (the "Guidelines"). Under the EC Philosophy, so long as the Guidelines are met, executives may sell unrestricted stock. It is preferred that executives own shares of common stock for a period greater than 12 months before selling such shares. All executive transactions in common stock must be made in compliance with our Insider Trading Policy.
The Guidelines encourage executives to own common stock with a value equal to at least one times their annual base salary. Executive ownership is calculated considering holdings of restricted stock, whether or not such holdings have vested, private holdings, shares held in retirement accounts and other shares attributed to the executive in accordance with Section 16 of the Exchange Act.
34

As of December 31, 2025, Mr. Smith did not have sufficient holdings to meet the Guidelines primarily as a result of the Company’s closing stock price as of December 31, 2025. The Guidelines provide executives with a reasonable period of time to become compliant with the guidelines.
Clawback Policy
Pursuant to Rule 10D-1 of the Exchange Act and applicable Nasdaq listing rules, we have adopted a policy for recovery of incentive-based compensation from our current and former Section 16 executive officers under certain circumstances. Incentive-based compensation is any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure. The policy provides that, in the event that we are required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities laws, and the noncompliance resulted in overpayment of the incentive-based compensation received by an executive officer within the three completed fiscal years preceding the date the restatement was required, then the company will recover from its executive officers, on a reasonably prompt basis, the amount of any such erroneously awarded incentive-based compensation to an executive officer. Erroneously awarded incentive-based compensation is the excess of the amount of incentive-based compensation received by current and former executive officers over the amount of incentive-based compensation that otherwise would have been received had it been determined based on the restated amounts.

PAY VERSUS PERFORMANCE
As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the following disclosure (the "Pay Versus Performance Disclosure") describes the relationship between executive compensation and the Company's performance with respect to select financial measures. For a complete description regarding the Company's compensation program, please see "Executive Compensation."

(1)Compensation for the Company's Principal Executive Officer (the "PEO"), Robert Rasmus for 2025, 2024 and from July 17, 2023 through the end of 2023, and Greg Marken from January 1, 2023 through July 17, 2023, reflects the amount reported in the "Summary Compensation Table" for the respective years. Average compensation for non-PEO NEOs is based on the compensation for Claiborne Smith and Jeremy Williamson for 2025, Jeremy Williamson, and Joe Wong for 2024, and Morgan Fields, Jeremy Williamson, and Joe Wong for 2023 (collectively, the "non-PEO NEOs") reported in the "Summary Compensation Table" for the respective years.
(2)SEC rules require that certain adjustments be made to the total compensation set forth in the "Summary Compensation Table" in order to determine "compensation actually paid" for purposes of this Pay Versus Performance Disclosure. "Compensation actually paid" does not represent cash and/or equity value transferred to the applicable NEO, but rather is a value calculated under applicable SEC rules. The below table reflects the required adjustments to reconcile total compensation as set forth in the Summary Compensation Table to "compensation actually paid" for purposes of the Pay Versus Performance Disclosure.
(3)Total shareholder return, or TSR, is calculated based on the value of an initial fixed $100 investment in the Company. Further, the TSR is cumulative for the measurement periods beginning on December 31, 2022 and ending on December 31 of each of 2023, 2024 and 2025, respectively, calculated in accordance with Item 201(e) of Regulation S-K.
(4)Reflects "Net Loss" as reported in the Company's Consolidated Statements of Operations included in the Company's Annual Reports on Form 10-K for each of the years ended December 31, 2025, 2024 and 2023.

Fair values of equity awards set forth in the table above are computed in accordance with FASB ASC Topic 718 as of the end of the respective fiscal year, other than fair values of equity awards that vest in the covered year, which are valued as of the applicable vesting date. The valuation methodologies applied do not materially differ from the valuation methodologies applied at the time of grant.

Relationships Between Executive Compensation Actually Paid and Select Financial Performance Measures
The charts below are based on the information provided in the above table to illustrate the relationships between the Company's compensation actually paid to the PEO and the average compensation actually paid to the Company's non-PEO NEOs, and (i) the Company's cumulative TSR and (ii) the Company's net loss.
Compensation actually paid to Mr. Rasmus and the non-PEO NEOs is primarily comprised of changes in fair value of unvested RSA and PSU awards driven by increases and decreases in Arq, Inc. common share prices from the grant date of July 17, 2023 to the end of our 2025 fiscal year. Arq, Inc.’s common stock closed at $1.59 on July 17, 2023, $2.98 on December 31, 2023 and $7.57 on December 31, 2024, and $3.27 on December 31, 2025.

PROPOSAL THREE
RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
Our Audit Committee has appointed Baker Tilly US, LLP ("Baker Tilly") to be the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. Baker Tilly has served as the Company's independent registered public accounting firm since 2025, the year in which it merged with the Company’s former independent registered public accounting firm Moss Adams, LLC, which had served as the Company's independent registered public accounting firm since 2017, including the fiscal year ended December 31, 2017.
On June 3, 2025, we were notified that Moss Adams, the Company's former independent registered public accounting firm, merged with Baker Tilly US, LLP, effective June 3, 2025. In connection with the merger, Moss Adams resigned as the auditors of the Company, and our Audit Committee approved the appointment of Baker Tilly to succeed Moss Adams as the Company's independent registered public accounting firm.
The audit reports of Moss Adams on the Company’s consolidated financial statements for the years ended December 31, 2024 and 2023, and for the years then ended, and internal control over financial reporting as of December 31, 2024, did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.
During the years ended December 31, 2024 and 2023, and the subsequent interim period preceding Moss Adams’ resignation, there were no (a) disagreements with Moss Adams on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Moss Adams’ satisfaction, would have caused it to make reference to the subject matter of the disagreement in connection with its reports on the Company’s financial statements, or (b) reportable events requiring disclosure pursuant to Item 304(a)(1)(v) of Regulation S-K.
During the years ended December 31, 2024 and 2023, and the subsequent interim period through the date of Baker Tilly’s appointment, neither the Company, nor anyone on its behalf, consulted with Baker Tilly regarding: (i) either the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements or (ii) any matter that was either the subject of a "disagreement," as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to that item, or a "reportable event," as described in Item 304(a)(1)(v) of Regulation S-K.
Stockholder ratification of the Audit Committee's selection of Baker Tilly as our independent registered public accounting firm as requested in Proposal 3 is not required by our bylaws or otherwise. The Board is submitting this proposal to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain this firm. This proposal will be deemed approved if the votes cast in favor of the proposal exceed the votes cast opposing the proposal.
We anticipate that a representative of Baker Tilly will be available at the Annual Meeting to respond to stockholder questions and will have the opportunity to make a statement at that time if the representative desires to do so.
Additional information about Audit Fees and Audit Committee Approval of Services can be found under the Independent Registered Public Accounting Firm section of this Proxy Statement.
Board Recommendation
Our Board recommends a vote "FOR" the ratification of the Audit Committee's appointment of Baker Tilly US, LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026.
38

REPORT OF THE AUDIT COMMITTEE
The Audit Committee's role and functions are described under the "Corporate Governance" section of this Proxy Statement.
The Audit Committee held four meetings in 2025. The Audit Committee has (i) reviewed and discussed the Company's consolidated audited financial statements for the year ended December 31, 2025 with the Company's management; (ii) discussed with the Company's current independent registered public accounting firm, Baker Tilly, the matters required to be discussed by Public Company Accounting Oversight Board ("PCAOB") and the SEC; (iii) received the written disclosures and the letter from Baker Tilly required by applicable requirements of the PCAOB regarding Baker Tilly's communications with the Audit Committee concerning independence and has discussed with Baker Tilly the independence of Baker Tilly; and (iv) discussed and reviewed with the Company's management and Baker Tilly other SEC filings occurring during the year ended December 31, 2025.
Based on the review and discussions with management and Baker Tilly, the Audit Committee recommended to the Board that the audited consolidated financial statements for the fiscal years ended December 31, 2025 and 2024 be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025.
On February 27, 2026, the Audit Committee approved the engagement of Baker Tilly to serve as the Company's independent registered public accounting firm to audit the Company's financial statements for the fiscal year ending December 31, 2026. This appointment for 2026 was based on the Audit Committee's and management's completion of a written evaluation of Baker Tilly's performance which included, among other criteria, quality of services provided; sufficiency of the firm's resources; communications and interaction; and independence, objectivity and professional skepticism.
Respectfully submitted,

The Audit Committee: | Laurie Bergman, Chair
| Richard Campbell-Breeden
| Carol Eicher

(3) This category consists of fees for tax compliance, tax advice and tax planning services. We did not pay our independent registered public accounting firm tax fees for services during the years ended December 31, 2025 and 2024.
(4) This category consists of fees for services that are not included in the above categories. We did not pay our independent registered public accounting firm any other fees for services during the years ended December 31, 2025 and 2024.
There were no disagreements on matters of accounting principles or practices, financial statement disclosures or audit scope or procedures between the Company and Baker Tilly during the most recent fiscal year or during the subsequent year.
AUDIT COMMITTEE APPROVAL OF SERVICES
The Audit Committee pre-approves all audit or non-audit services performed by our independent registered public accounting firm in accordance with Audit Committee policy and applicable law. The Audit Committee generally provides pre-approval of audit services and services associated with SEC registration statements, other SEC filings and responses to SEC comment letters (audit fees) and services related to internal control reviews, internal control reporting requirements and consultations with our management as to accounting or disclosure treatment of transactions or events and the impact of rules, standards or interpretations by the SEC and other regulatory or standard-setting bodies (audit-related fees) for each 12 month period within a range of approved fees. To avoid certain potential conflicts of interest, the law prohibits the Company from obtaining certain non-audit services from its independent registered public accounting firm. The Audit Committee has delegated authority to approve permissible services to its Chair. The Chair reports such pre-approvals to the full Audit Committee at its next scheduled meeting. The Audit Committee Chair pre-approved 100% of the services provided by the Company’s independent registered public accounting firm in 2025. None of the services of the independent registered public accounting firms in 2025 were of the type specified in Rule 2-01(c)(7)(i)(C) of Regulation S-X.

PROPOSAL FOUR
APPROVAL OF THE ARQ, INC. 2026 OMNIBUS INCENTIVE PLAN
The Board believes that attracting and retaining highly qualified officers and key employees and motivating them to serve the Company and to expend maximum efforts are important to our continued growth and success. In this regard, stock-based awards have been and will continue to be an important element of our compensation program because they enable our officers and other key employees to acquire or increase their proprietary interest in the operations and future success of our Company, thereby aligning interests between such individuals and our stockholders.
Our current equity compensation plan, the 2024 Omnibus Incentive Plan (the "2024 Plan"), had 998,538 shares of common stock authorized for issuance as of April 14, 2026, which we believe is insufficient to cover future stock-based awards. The Board believes that stock-based awards to key employees, officers and non-employee directors serve the best interests of stockholders by promoting a long-term focus for such individuals to increase the value of our common stock. Accordingly, on April 14, 2026, the Board adopted, subject to stockholder approval, the Arq, Inc. 2026 Omnibus Incentive Plan (the "2026 Plan"). If stockholder approval is obtained for the 2026 Plan, we will cease granting awards under the 2024 Plan. If our stockholders do not approve the 2026 Plan, we will continue to grant awards under the 2024 Plan until its termination date or until such time as no shares of common stock remain available for issuance thereunder. While we could increase cash compensation if we are unable to grant stock-based incentives, replacing equity awards with cash awards would not only misalign our executive and stockholder interests, it would also increase cash compensation expense and divert cash that could otherwise be reinvested in our business.
The Board has approved the reservation of 1,500,000 shares of common stock under the 2026 Plan. We expect this share reserve to provide enough shares for awards for approximately 2 to 3 years, assuming we continue to grant awards consistent with our current practices and historical usage, as reflected in our average three-year burn rate in the table below, and noting that future circumstances may require us to change our current equity grant practices. The 2026 Plan provides for the grant of options (both nonqualified stock options ("NSOs") and incentive stock options ("ISOs")), stock appreciation rights ("SARs"), restricted stock, restricted stock units ("RSUs"), Performance Stock Units ("PSUs"), other stock-based awards and cash-based awards.
Because of their expected participation in the 2026 Plan our current directors and executive officers may be deemed to have an interest in this matter.
Burn Rate Analysis
Our burn rate for our equity plan is calculated below.
We measure our burn rate as (a) the number of shares subject to issuance under our equity-based awards granted in a fiscal year, divided by (b) the weighted average number of shares of common stock outstanding for that fiscal year. We measure our fully diluted burn rate as (i) the number of shares subject to issuance under our equity-based awards granted in a fiscal year, divided by (ii) the weighted average number of diluted shares of common stock outstanding for that fiscal year. The number of shares subject to issuance under our equity-based awards in a given year is variable, and dependent upon the share price at the time of the grant. Over the last three fiscal years, our average annual burn rate was 2.56%, and our average annual fully diluted burn rate was 2.56%. We do not currently expect significant changes to our historical equity award granting process or award levels as compared to our average over the last three years under our existing equity compensation plans, as set forth in the table below.

Fiscal Year |  | Total Awards Granted(1) |  | Weighted average number of common shares outstanding |  | Burn Rate |  | Weighted average number of diluted common shares outstanding |  | Fully Diluted Burn Rate
2025 |  | 961,105 |  |  | 41,522,393 |  |  | 2.31% |  | 41,522,393 |  |  | 2.31%
2024 |  | 769,085 |  |  | 36,051,523 |  |  | 2.13% |  | 36,051,523 |  |  | 2.13%
2023 |  | 773,327 |  |  | 29,103,775 |  |  | 2.66% |  | 29,103,775 |  |  | 2.66%
Three-Year Average |  | 834,506 |  |  | 32,577,649 |  |  | 2.56% |  | 32,577,649 |  |  | 2.56%

41

(1) Does not include the inducement grant of one million stock options granted to Mr. Rasmus in 2023, which were not granted under the 2024 Plan. PSUs are included in the total equity awards granted for the fiscal year in which the PSUs are earned. A tabular reconciliation of PSUs granted and earned by year is as follows:

Fiscal Year |  | PSUs Granted |  | PSUs Earned
2025 |  | 122,630 |  |  | 182,204 |
2024 |  | 101,477 |  |  | 191,926 |
2023 |  | 582,709 |  | (A) | — |

(A) Does not include the inducement grant of 400,000 PSUs granted to Mr. Rasmus in 2023, which were not granted from the 2024 Plan.
Key Features and Best Practices of the 2026 Plan
The 2026 Plan contains a number of best practices designed to protect stockholders and reflect good corporate governance principles, including the following:
▪Minimum One-Year Vesting Requirement. Except for awards with respect to 5% of the shares reserved for issuance under the 2026 Plan, awards are subject to a minimum vesting period of at least one year.
▪No Dividends or Dividend Equivalents on Unvested Awards. Dividends and dividend equivalents on awards accrue but will not be paid until the underlying award vests.
▪Term Limits on Options and SARs. Options and SARs are subject to a maximum term of 10 years.
▪No Discounted Options or SARs. Options and SARs may not be granted with an exercise or grant price at a discount to the fair market value of our common stock on the date of grant.
▪No Repricing. The 2026 Plan prohibits the reduction of the exercise price or grant price for outstanding options or SARs and prohibits the surrender of outstanding options or SARs for cash or a new award with a lower or no exercise price or grant price, in each case, without the approval of our stockholders.
▪No Tax Gross-Ups. The 2026 Plan does not provide for any tax gross-ups on awards.
▪No Liberal Share Recycling. The 2026 Plan prohibits liberal share recycling on all awards.
▪Director Compensation Limit. The 2026 Plan contains an annual limit on cash and equity-based compensation that may be paid or granted, to non-employee directors of $350,000 (or $400,000 in a non-employee director’s first year of service or if the non-employee director is serving as chairman or lead director).
▪Clawback Provisions. Awards will be subject to any clawback policy adopted by the Company and any other clawback or recoupment provisions set forth in any award agreement. Under the 2026 Plan, awards are subject to mandatory clawback or recoupment in the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to the Company’s material non-compliance with any financial reporting requirement under the federal securities laws. Additionally, the 2026 Plan includes a permissive clawback provision through which the Compensation Committee of the Board may require clawback or recoupment of awards if a Forfeiture Event (as defined in the 2026 Plan) occurs with respect to any 2026 Plan participant, which events include, but are not limited to, instances of an accounting restatement that results from misconduct or gross negligence, fraud, embezzlement, or intentional reputational harm inflicted by a 2026 Plan participant.
▪No Evergreen Provisions. The 2026 Plan does not contain any provisions that would allow for "evergreen" increases in amount of common stock subject to the 2026 Plan or the automatic "reload" of awards.
▪Administration by Independent Directors. The 2026 Plan is administered by the Compensation Committee of the Board, which is comprised of independent directors.
Summary of the 2026 Plan
The following summary of the 2026 Plan is qualified by reference to the full text of the 2026 Plan, a copy of which is attached to this Proxy Statement as Appendix A.
42

Administration. The 2026 Plan is administered by our Compensation Committee or any committee designated by the Board consisting of two or more members of the Board, each of whom is intended to be a "non-employee director" within the meaning of Rule 16b-3 of the Exchange Act and an "independent director" under the Nasdaq Marketplace Rules (or the rules of any securities exchange on which the common stock is listed). For purposes of this summary of the 2026 Plan, the Compensation Committee or other designated committee will be referred to as the "Committee."
Subject to the terms and conditions of the 2026 Plan, the Committee is authorized to select participants who are employees, directors or consultants of the Company or its subsidiaries, determine the awards to be made, set terms and conditions of such awards, determine the form of award agreements, and establish performance goals for any performance period and determine whether such goals were satisfied. The Committee also has the authority, among other things, to: (i) amend the terms of any outstanding award, subject to the repricing restrictions described below, so long as such amendment does not adversely affect a participant’s rights without the participant’s written consent, (ii) construe and interpret the terms of the 2026 Plan and any award agreement and to decide all questions of fact arising in its application, and (iii) take such other action, not inconsistent with the terms of the 2026 Plan, as it deems appropriate.
Eligibility. Any employee, director, or consultant of the Company or its subsidiaries is eligible to receive awards under the 2026 Plan. As of the date of this Proxy Statement, there are currently five non-employee directors, four executive officers, 179 other employees and zero consultants who are eligible under the 2026 Plan.
Limitations under the 2026 Plan
Minimum Vesting Requirements. Except for awards with respect to 5% of the shares reserved for issuance under the 2026 Plan, all awards granted under the 2026 Plan must be granted with a minimum vesting period of at least one year without providing for incremental vesting during such one-year period.
Individual Limit. The 2026 Plan contains an annual limit on cash and equity-based compensation that may be paid or granted, whether under the 2026 Plan or otherwise, to non-employee directors of $350,000 (or $400,000 in a non-employee director’s first year of service or if the non-employee director is serving as chairman or lead director).
Shares Subject to the 2026 Plan. Subject to the adjustments upon changes in capitalization described below, 1,500,000 shares of common stock will be authorized for issuance of awards under the 2026 Plan, plus (i) any shares of common stock that remain available for grant under the 2024 Plan as of the date of stockholder approval of the 2026 Plan and (ii) any shares of common stock that become available for issuance under the 2026 Plan as described below. For purposes of determining the number of shares remaining available for issuance under the 2026 Plan, to the extent an award under either the 2026 Plan, 2024 Plan, or 2022 Omnibus Incentive Plan is canceled, forfeited, or expires prior to exercise or realization or is settled in cash, the shares retained or returned to the Company will again be available for grant under the 2026 Plan. However, the following shares shall not be available for reissuance: shares tendered or withheld in payment of the exercise price; shares covered by, but not issued upon settlement of, stock-settled SARs; shares delivered to, or withheld by, the Company to satisfy any tax withholding obligation; and shares purchased on the open market with option proceeds. Shares issued under the 2026 Plan may be authorized but unissued shares or treasury shares.
The number of shares authorized for issuance of awards is subject to adjustment in the event of any stock dividend, stock split, spin off, rights offering, recapitalization through a large, nonrecurring cash dividend, or in the event of any other change in corporate capitalization, such as a merger, consolidation, any reorganization or any partial or complete liquidation of the Company.
As of April 14, 2026, we had a total of 42,876,258 shares of common stock outstanding, and the closing price per share of common stock as reported on the Nasdaq Global Market was $2.24.
Term of the 2026 Plan. No awards may be granted under the 2026 Plan after June 9, 2036 or such earlier date as the Board shall determine.
Types of Awards
Options and SARs: The Committee is authorized to grant options as either ISOs, which can result in potentially favorable tax treatment to the participant under the Internal Revenue Code of 1986 (the "Code"), or NSOs, and
43

SARs under the 2026 Plan. The exercise or grant price per share of common stock subject to an option or SAR must be at least the fair market value of the underlying stock at the date of grant; provided, however, that an ISO granted to a participant who is the holder of record of more than 10% of the common stock must have an exercise price of at least 110% of the fair market value of the underlying common stock at the date of grant. The term of each option and SAR and the times at which each option or SAR shall be exercisable generally will be fixed by the Committee, except that no option or SAR will have a term exceeding 10 years; provided, however, that an ISO granted to a participant who is the holder of record of more than 10% of the common stock will have a term not exceeding five years. Upon the termination of employment or service with us, the ability to exercise vested options and SARs and the expiration of such options and SARs will be determined in the discretion of the Committee as set forth in the applicable award agreement.
Restricted Stock and RSUs: The Committee may grant shares of restricted stock or RSUs (representing a right to receive shares of common stock, a cash equivalent amount or combination thereof) under the 2026 Plan. The Committee determines in the award agreement the restriction period during which the restricted stock or the RSUs are subject to a substantial risk of forfeiture based upon the passage of time, the achievement of performance goals or the occurrence of other events determined by the Committee. The Committee may impose other conditions, including a requirement that the participant pay a specified amount to purchase each share of restricted stock, restrictions based upon the achievement of specific performance goals, time-based restrictions on vesting, or holding requirements or sale restrictions upon vesting. Each award agreement will set forth the extent to which participants shall have the right to retain unvested restricted stock or RSUs following termination of employment or service.
Unless otherwise determined by the Committee or set forth in an award agreement, participants holding restricted stock generally may vote the shares. The Committee may provide in an award agreement that the holder of restricted stock may receive any dividends paid; however, such dividends must be subject to the same vesting conditions as the underlying restricted stock. Participants holding RSUs will have no rights of stockholders. The Committee may provide in an award agreement that the holder of such RSUs will be entitled to receive dividend equivalents; however, such dividend equivalents must be subject to the same vesting conditions as the underlying RSUs.
PSUs: The Committee may grant PSUs under the 2026 Plan. The Committee determines in the award agreement the applicable performance periods and performance measures. Earned PSUs may be settled in shares of common stock, a cash equivalent amount or a combination thereof, as set forth in the award agreement. Each award agreement will set forth the extent to which participants will have the right to receive a payout with respect to their PSUs following termination of employment or service. Participants holding PSUs will have no rights of stockholders. The Committee may provide in an award agreement that the holder of such PSUs will be entitled to receive dividend equivalents; however, such dividend equivalents must be subject to the same vesting and performance conditions as the underlying PSUs.
Other Stock-Based and Cash-Based Awards: The Committee may adopt other incentive arrangements under which participants may acquire shares of common stock by purchase, grant or otherwise, or receive an award payable in cash or common stock the value of which may be determined in whole or in part based on the value of the common stock. The Committee may also adopt other incentive arrangements under which participants may be awarded cash payments.
No Repricing. The 2026 Plan prohibits the reduction of the exercise price or grant price for outstanding options or SARs and prohibits the surrender of outstanding options or SARs for cash or a new award with a lower or no exercise price or grant price, in each case, without the approval of our stockholders.
Replacement Awards. Awards may be granted in replacement of outstanding awards previously granted by an entity acquired by the Company or an affiliate, or with which the Company or an affiliate combines, as permitted under the terms of the 2026 Plan.
Transferability. Under the 2026 Plan, ISOs may not be sold, transferred, pledged, assigned or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution, and will be exercisable during a participant’s lifetime only by the participant. Other awards under the 2026 Plan will be transferable by will, by the laws of descent and distribution or, solely to the extent and in the manner authorized by the Committee, by transfer to members of the participant’s immediately family or pursuant to a qualified domestic relations order.
44

Adjustments and Change in Control. The 2026 Plan provides that, in the event of any non-reciprocal transaction between the Company and the stockholders of the Company that causes any change in our capital structure that effects an increase or decrease in the number of shares of our common stock without receipt of consideration, the maximum number of shares of common stock for which awards may be made under the 2026 Plan may be proportionately increased or decreased, and the number and kind of shares for which awards are outstanding may be proportionately increased or decreased. Any such adjustments will be in compliance with Section 409A of the Code.
Upon a change in control, outstanding awards will become fully vested and exercisable if such awards are not assumed, converted or replaced by the continuing entity. If such awards are assumed, converted or replaced by the continuing entity, then unless otherwise provided in an award agreement, such assumed, converted or replaced awards will vest in the event of a participant’s termination without cause or a resignation with good reason within 12 months following the change in control. In addition, the Committee will have the discretion to provide for the termination and cash-out of outstanding awards (and the cancellation for no payment for underwater options and SARs) upon a change in control.
Amendment and Termination. The Board may alter, amend, suspend or terminate the 2026 Plan at any time, subject to stockholder approval requirements under the Nasdaq listing standards or other applicable laws.
Tax Withholding. The Company may withhold from any payments or stock issuances under the 2026 Plan, or collect as a condition of payment, any taxes required by law to be withheld.
Clawback. Awards under the 2026 Plan will be subject to any clawback policy adopted by the Company and any other clawback or recoupment provisions set forth in any award agreement. Under the 2026 Plan, awards are subject to mandatory clawback or recoupment in the event the Company is required to prepare an accounting restatement of the Company’s financial statements due to the Company’s material non-compliance with any financial reporting requirement under the federal securities laws. Additionally, the 2026 Plan includes a permissive clawback provision through which the Compensation Committee of the Board may require clawback or recoupment of awards if a Forfeiture Event (as defined in the 2026 Plan) occurs with respect to any 2026 Plan participant, which events include, but are not limited to, instances of an accounting restatement that results from misconduct or gross negligence, fraud, embezzlement, or intentional reputational harm inflicted by a 2026 Plan participant.
Federal Tax Consequences of the 2026 Plan
The following is a summary of the U.S. federal income tax treatment applicable to us and the participants who receive awards under the 2026 Plan based on the federal income tax laws in effect on the date of this Proxy Statement. This summary is not intended to be exhaustive and does not address all matters relevant to a particular participant based on their specific circumstances. The summary expressly does not discuss the income tax laws of any state, municipality, or non-U.S. taxing jurisdiction, or the gift, estate, or other tax laws other than U.S. federal income tax law. Because individual circumstances may vary, we recommend that all participants consult their own tax advisor concerning the tax implications of awards granted under the 2026 Plan.
Option Grants. Options granted under the 2026 Plan may be either ISOs, which satisfy the requirements of Section 422 of the Code, or NSOs, which are not intended to meet such requirements. The U.S. federal income tax treatment for the two types of options differs as follows:
Incentive Stock Options. No taxable income is recognized by the optionee at the time of the ISO grant, and no taxable income is recognized for ordinary income tax purposes at the time the ISO is exercised, although taxable income may arise at that time for alternative minimum tax purposes. Unless there is a disqualifying disposition, as described below, the optionee will recognize long-term capital gain in an amount equal to the excess of (a) the amount realized upon the sale or other disposition of the purchased shares over (b) the exercise price paid for the shares. A disqualifying disposition occurs if the disposition is less than two years after the date of grant or less than one year after the exercise date. If there is a disqualifying disposition of the shares, then the excess of (i) the fair market value of those shares on the exercise date or (if less) the amount realized upon such sale or disposition over (ii) the exercise price paid for the shares will be taxable as ordinary income to the optionee. Any additional gain or loss recognized upon the disposition will be a capital gain or loss.
If the optionee makes a disqualifying disposition of the purchased shares, then we will be entitled to an income tax deduction for the taxable year in which such disposition occurs, equal to the amount of ordinary income recognized
45

by the optionee as a result of the disposition. We will not be entitled to any income tax deduction if the optionee makes a qualifying disposition of the shares.
Nonqualified Stock Options. No taxable income is recognized by an optionee upon the grant of an NSO. The optionee in general will recognize ordinary income, in the year in which the NSO is exercised, equal to the excess of the fair market value of the purchased shares on the exercise date over the exercise price paid for the shares, and the optionee will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the optionee with respect to the exercised non-statutory option.
SARs. No taxable income is recognized upon receipt of a SAR. The holder will recognize ordinary income in the year in which the SAR is exercised equal to the amount of cash or the fair market value of the common stock received as of the exercise date, and the holder will be required to satisfy the tax withholding requirements applicable to such income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder in connection with the exercise of the SAR.
Restricted Stock Awards. The recipient of unvested shares of common stock will not recognize any taxable income at the time those shares are issued but will have to report as ordinary income, as and when the restrictions lapse, an amount equal to the excess of (a) the fair market value of the shares on such date over (b) the cash consideration (if any) paid for the shares. The recipient may, however, elect under Section 83(b) of the Code to include as ordinary income in the year the award is granted an amount equal to the excess of (i) the fair market value of those shares on the issue date over (ii) the cash consideration (if any) paid for such shares. If the Section 83(b) election is made, the recipient will not recognize any additional income as and when the restrictions subsequently lapse. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the recipient with respect to the award at the time such ordinary income is recognized by the recipient.
RSUs, PSUs, Other Stock-Based Awards, Other Cash-Based Awards. No taxable income is recognized upon receipt of RSUs, PSUs, other stock-based awards or other cash-based awards. The holder will recognize ordinary income in the year in which the shares or cash subject to the award are actually issued or in the year in which the award is settled in cash. The amount of that income will be equal to the fair market value of the shares on the date of issuance or the amount of the cash paid in settlement of the award, and the holder will be required to satisfy the tax withholding requirements applicable to the income. We will be entitled to an income tax deduction equal to the amount of ordinary income recognized by the holder at the time the shares are issued or the cash amount is paid.
Deductibility of Executive Compensation. Section 162(m) of the Code limits the amount of compensation paid to certain covered employees that we may deduct for federal income tax purposes to $1 million per employee per year. Under Section 162(m), "covered employees" consist of any individual who served as our chief executive officer, chief financial officer or one of the other three most highly compensated executive officers for the taxable year. Once an individual becomes a covered employee for any taxable year beginning after December 31, 2016, that individual will remain a covered employee for all future years, including after termination of employment or even death. As a result, compensation payable to a covered employee under the 2026 Plan that might otherwise be deductible may not be deductible by us if all compensation paid to the employee for the taxable year exceeds $1 million.
Section 409A of the Code. If any award constitutes non-qualified deferred compensation under Section 409A of the Code, it will be necessary that the award be structured to comply with Section 409A of the Code to avoid the imposition of additional tax, penalties, and interest on the participant.
Tax Consequences of a Change of Control. If upon a change of control of the Company, the exercisability, vesting, or payout of an award under the 2026 Plan is accelerated, any excess on the date of the change of control of the fair market value of the shares or cash issued under accelerated awards over the purchase price of such shares, if any, may be characterized as “parachute payments” (within the meaning of Section 280G of the Code) if the sum of such amounts and any other such contingent payments received by certain covered participant exceeds an amount equal to three times the “base amount” for such participant. The base amount generally is the average of the annual compensation of the participant for the five years preceding such change in ownership or control. An "excess parachute payment," with respect to any covered participant, is the excess of the parachute payments to such person, in the aggregate, over and above such person’s base amount. If the amounts received by a covered participant upon a
46

change of control are characterized as parachute payments, the participant will be subject to a 20% excise tax on the excess parachute payment and we will be denied any deduction with respect to such excess parachute payment.
Deductibility of Executive Compensation. Section 162(m) of the Code limits the deductibility for federal income tax purposes of certain compensation paid to any "covered employee" in excess of $1 million. For purposes of Section 162(m), the term “covered employee” includes any individual who serves as chief executive officer, chief financial officer or one of the other three most highly compensated executive officers for any calendar year. It is expected that compensation deductions for any covered employee with respect to awards under the 2026 Plan will be subject to the $1 million annual deduction limitation. The Committee may grant awards under the 2026 Plan or otherwise that is or may become non-deductible when it believes doing so is in the best interests of the Company and our shareholders.
New Plan Benefits
As described above, the selection of participants who will receive awards under the 2026 Plan and the size and types of awards will be determined by the Committee in its discretion. Therefore, the amount of any future awards under the 2026 Plan is not yet determinable and it is not possible to predict the benefits or amounts that will be received by, or allocated to, particular individuals or groups of employees.
For illustrative purposes, the following table sets forth the number of shares subject to awards previously granted under the 2024 Plan during the year ended December 31, 2025 and through our record date of April 14, 2026 to our NEOs, all executive officers as a group, all non-employee directors as a group, and all employees, other than executive officers, as a group:

(1) In accordance with the terms of the Employment Agreement between the Company and Mr. Rasmus dated July 17, 2023, the Company made the following employment inducement awards to Mr. Rasmus in accordance with Nasdaq Listing Rule 5635(c)(4), which authorizes employment inducement awards without stockholder approval: (a) an option to purchase 1,000,000 shares of the Company’s common stock at an exercise price of $3.00 (which represents a premium priced option based on the $1.59 closing price on the date of grant), which option vests ratably in three equal annual installments, and (b) 400,000 performance-based restricted stock units ("PSUs"), which vests as to 250,000 PSUs when the volume weighted average price ("VWAP") of the Company’s common stock over a 30-day period equals $10.00 per share and as to 150,000 PSUs when the VWAP over a 30-day period equals $15.00 per share, in each case, prior to July 17, 2026. In the event Mr. Rasmus is terminated without cause or resigns for good reason (as such terms are defined in the Employment Agreement), the inducement option award will vest. In addition, the inducement PSU award agreement provides for accelerated vesting if such termination without cause or resignation for good reason occurs more than 18 months but less than three years following July 17, 2023.
Board Recommendation

PROPOSAL FIVE
APPROVAL OF THE NINTH AMENDMENT TO THE COMPANY'S TAX ASSET PROTECTION PLAN
The Board is asking stockholders to approve the Tax Asset Protection Plan, as amended on April 6, 2018, April 5, 2019, April 8, 2020, April 9, 2021, March 15, 2022, April 13, 2023, April 15, 2024, April 8, 2025, and April 15, 2026 (the "TAPP"). If our stockholders do not approve the TAPP at the Annual Meeting, the TAPP will expire on December 31, 2026.
Background
We believe that we have valuable tax attributes which are significant assets of the Company. As of December 31, 2025, we had several domestic tax attributes, which includes federal net operating losses and general business credit carry-overs of approximately $86.1 million (the "Tax Assets"). Under the Internal Revenue Code and regulations promulgated by the U.S. Treasury Department, the Company may carry forward or otherwise utilize these Tax Assets in certain circumstances to offset any current and future taxable income or reduce the Company’s federal income tax liability, subject to certain requirements and restrictions. To the extent that the Tax Assets do not otherwise become limited, the Company believes that it will have available a significant amount of Tax Assets in future years, and therefore these Tax Assets could be a substantial asset to the Company.
Our ability to use the Tax Assets could be substantially limited or delayed, however, if we experience an "ownership change," as defined in Section 382 of the Internal Revenue Code. In general, an ownership change occurs if there is a cumulative change in the ownership of the Company by "5-percent shareholders" (as defined for purposes of Section 382 of the Internal Revenue Code) that exceeds 50 percentage points over an applicable testing period (which is generally a rolling three-year period). Accordingly, on May 5, 2017, after consultation with the Company’s legal and tax advisors, the Board adopted the TAPP in order to protect the Company's ability to utilize its Tax Assets and on April 6, 2018, April 5, 2019, April 8, 2020, April 9, 2021, March 15, 2022, April 13, 2023, April 12, 2024, and April 4, 2025 the Board amended the TAPP to extend the expiration thereof. On April 14, 2026 the Board approved ninth amendment to the TAPP to further extend the expiration thereof.
Calculating whether an "ownership change" has occurred is subject to uncertainty. This uncertainty arises from the complexity and ambiguity inherent in Section 382 of the Internal Revenue Code, as well as limitations on the knowledge that any publicly traded company can have about the ownership of and transactions in its securities. We have analyzed the information available, along with various scenarios of possible future changes in ownership. In light of this analysis, we believe that, in the absence of the TAPP, it is possible that we could undergo a subsequent "ownership change" under Section 382 of the Internal Revenue Code, which would substantially reduce our ability to utilize the Tax Assets. We believe the continuation of the TAPP will serve the interests of all stockholders given the size of the Tax Assets and the potential loss of value should changes in our stock ownership occur that are sufficient to cause a 50 percentage point or greater "ownership change."
The TAPP is intended to protect the tax assets of the Company and to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of the Company’s outstanding stock without the approval of the Board. Stockholders who beneficially owned 4.99% or more of the Company’s outstanding stock upon execution of the TAPP will not trigger the TAPP so long as they do not acquire beneficial ownership of additional shares of stock. The Board may, in its sole discretion, also exempt any person from triggering the TAPP.
If the stockholders do not approve the TAPP, the TAPP will expire on December 31, 2026. If the stockholders approve the TAPP, it will expire on the earlier of (a) December 31, 2027, (b) the time at which the Rights (described below) are redeemed pursuant to the TAPP, (c) the time at which the Rights are exchanged in full pursuant to the TAPP, (d) the effective date of the repeal of both Section 382 and Section 383 of the Internal Revenue Code, or any successor provisions or replacement provisions, if the Board determines that the TAPP is no longer necessary for the preservation of tax benefits or (e) the beginning of a taxable year of the Company for which the Board determines that the Company has or will have no Tax Assets.

Summary of Terms of the TAPP
The following description of the terms of the TAPP does not purport to be complete and is qualified in its entirety by reference to the TAPP, which is attached as Appendix B and is incorporated herein by reference. We urge you to read carefully the TAPP in its entirety, as the discussion below is only a summary. Certain capitalized terms used herein have the meaning set forth in the TAPP.
The Rights. On May 5, 2017, the Board declared a dividend of one preferred share purchase right (each, a "Right") for each outstanding share of common stock to stockholders of record as of the close of business on May 22, 2017. One Right is also issued together with each share of common stock issued after May 22, 2017 but before the Distribution Date (as defined below) and, in certain circumstances, after the Distribution Date. Subject to the terms, provisions and conditions of the TAPP, if the Rights become exercisable, each Right would initially represent the right to purchase from the Company one ten-thousandth of a share of the Company’s Series B Junior Participating Preferred Stock, par value $0.001 per share (the "Series B Preferred Stock") for a purchase price of $50.00 (the "Purchase Price"). If issued, each fractional share of Series B Preferred Stock would give the stockholder approximately the same dividend, voting and liquidation rights as does one share of common stock. However, prior to exercise, a Right does not give its holder any rights as a stockholder of the Company, including, without limitation, any dividend, voting or liquidation rights.
Initial Exercisability. The Rights will not be exercisable until the earlier of (i) ten business days after a public announcement that a person has become an "Acquiring Person" by acquiring beneficial ownership of 4.99% or more of the Company's outstanding common stock, or, in the case of a person that had beneficial ownership of 4.99% or more of the Company's outstanding common stock upon execution of the TAPP, by obtaining beneficial ownership of additional shares of common stock or (ii) ten business days (or such later date as may be specified by the Board prior to such time as any person becomes an Acquiring Person) after the commencement of a tender or exchange offer by or on behalf of a person that, if completed, would result in such person becoming an Acquiring Person.
The date that the Rights become exercisable is referred to as the "Distribution Date." Until the Distribution Date, common stock certificates or the ownership statements issued with respect to uncertificated shares of common stock will evidence the Rights. Any transfer of shares of common stock prior to the Distribution Date will also constitute a transfer of the associated Rights. After the Distribution Date, separate rights certificates will be issued and the Rights may be transferred other than in connection with the transfer of the underlying shares of common stock unless and until the Board has determined to effect an exchange pursuant to the TAPP (as described below).
Flip-In Event. In the event that a person becomes an Acquiring Person, each holder of a Right, other than Rights that are or, under cer tain circumstances, were beneficially owned by the Acquiring Person (which will thereupon become null and void), will thereafter have the right to receive upon exercise of a Right and payment of the Purchase Price, a number of shares of common stock having a market value of two times the Purchase Price.
Redemption. At any time until a person becomes an "Acquiring Person", the Board may redeem the Rights in whole, but not in part, at a price of $0.00001 per Right (the "Redemption Price"). The redemption of the Rights may be made effective at such time, on such basis and with such conditions as the Board in its sole discretion may establish. Immediately upon any redemption of the Rights, the right to exercise the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price.
Exchange. At any time after a person becomes an Acquiring Person, the Board may exchange the Rights (other than Rights that have become null and void), in whole or in part, at an exchange ratio of one share of common stock, or a fractional share of Series B Preferred Stock (or of a share of a similar class or series of the Company’s preferred stock having similar rights, preferences and privileges) of equivalent value, per Right (subject to adjustment). Immediately upon an exchange of any Rights, the right to exercise such Rights will terminate and the only right of the holders of Rights will be to receive the number of shares of common stock (or fractional share of Series B Preferred Stock or of a share of a similar class or series of the Company’s preferred stock having similar rights, preferences and privileges) equal to the number of such Rights held by such holder multiplied by the exchange ratio. The Board shall not be empowered to effect such exchange at any time after an Acquiring Person becomes the beneficial owner of 50% or more of the Company’s outstanding common stock.
Expiration. The Rights and the TAPP will expire on the earlier of (i) the close of business on the earlier of (a) December 31, 2027, or (b) December 31, 2026 if stockholder approval has not been obtained prior to such date, (ii)
50

the time at which the Rights are redeemed pursuant to the TAPP, (iii) the time at which the Rights are exchanged in full pursuant to the TAPP, (iv) the effective date of the repeal of both Section 382 and Section 383 of the Internal Revenue Code, or any successor provisions or replacement provisions, if the Board determines that the TAPP is no longer necessary for the preservation of tax benefits or (v) the beginning of a taxable year of the Company for which the Board determines that the Company has or will have no tax benefits.
Anti-Dilution Provisions. The Board may adjust the Purchase Price, the number of shares of Series B Preferred Stock or other securities or assets issuable and the number of outstanding Rights to prevent dilution that may occur as a result of certain events, including among others, a stock dividend, a stock split or a reclassification of the Series B Preferred Stock or common stock. With certain exceptions, no adjustments to the Purchase Price will be required until cumulative adjustments amount to at least 1% of the Purchase Price.
Amendments. For so long as the Rights are redeemable, the Board may supplement or amend any provision of the TAPP in any respect without the approval of the holders of the Rights. From and after the time the Rights are no longer redeemable, the Board may supplement or amend the TAPP only to cure an ambiguity, to alter time period provisions, to correct inconsistent provisions, or to make any additional changes to the TAPP which the Company may deem necessary or desirable, but only to the extent that those changes do not impair or adversely affect any Rights holder (other than an Acquiring Person or any Affiliate or Associate of an Acquiring Person or certain of their transferees) and do not result in the Rights again becoming redeemable or the TAPP again becoming amendable other than in accordance with this sentence.
Exemptions. The Board, in its sole discretion may grant an exemption to any person, in whole or in part, prospectively or retroactively and which exemption may be subject to limitations or conditions to the extent the Board shall determine, in its sole discretion, necessary or desirable. The Board, in its sole discretion, may also exempt any transaction from the terms of the TAPP.
Certain Considerations Related to the TAPP
Our Board believes that protecting the Tax Assets is in the Company’s and our stockholders’ best interests. Nonetheless, we cannot eliminate the possibility that changes in our stock ownership will occur sufficient to cause an "ownership change" even if the TAPP is approved. You should consider the factors below when making your decision.
Future Use and Amount of the Tax Assets is Uncertain. Our use of the Tax Assets depends on our ability to generate taxable income in the future. We cannot assure you whether we will have taxable income in any applicable period or, if we do, whether such income or tax liability will exceed any potential Section 382 or Section 383 limitation and therefore we cannot assure you that we will realize the full value of the Tax Assets.
Potential Challenge to the Tax Assets. The amount of the Tax Assets has not been audited or otherwise validated by the Internal Revenue Service (the "IRS"). The IRS could challenge the amount of the Tax Assets, which could result in an increase in our liability for income taxes. In addition, determining whether an "ownership change" has occurred is subject to uncertainty, both because of the complexity and ambiguity of the Section 382 provisions and because of limitations on the knowledge that any publicly traded company can have about the ownership of, and transactions in, its securities on a timely basis. Therefore, we cannot assure you that the IRS or other taxing authority will not claim that we experienced an "ownership change" and attempt to reduce the benefit of the Tax Assets even if the TAPP is in place.
Continued Risk of Ownership Change. Although the TAPP is intended to diminish the likelihood of an "ownership change" under Section 382 of the Internal Revenue Code, we cannot assure you that it will be effective. The amount by which our ownership may change in the future could, for example, be affected by purchases and sales of stock by stockholders and new issuances or repurchases of stock by us, should we choose to do so.
Potential Effects on Liquidity. The TAPP is intended to deter persons or groups of persons from acquiring beneficial ownership of shares of our stock in excess of the specified limitation. A stockholder’s ability to dispose of our stock may be limited if the TAPP reduces the number of persons willing to acquire our stock or the amount they are willing to acquire.
51

Potential Impact on Value. The TAPP could negatively impact the value of our stock by deterring persons or groups of persons from acquiring shares of our stock, including in acquisitions for which some stockholders might receive a premium above market value.
Anti-Takeover Effect. Our Board adopted the TAPP to diminish the risk that our ability to use the Tax Assets to reduce potential federal income tax obligations becomes limited. Nonetheless, the TAPP may have an "anti-takeover effect" because it will deter a person or group of persons from acquiring beneficial ownership of 4.99% or more of our stock or, in the case of persons or persons that already own 4.99% or more of our stock, from acquiring any additional shares of our stock. The TAPP could discourage a merger, tender offer or accumulations of substantial blocks of shares of our stock.
Board Recommendation
The Board recommends that you vote "FOR" the approval of the Company’s Ninth Amendment to the Tax Asset Protection Plan.

OTHER MATTERS
The Board knows of no other business to be presented at the Annual Meeting. If other matters properly come before the Annual Meeting, to the extent permitted by law, the persons named in the accompanying form of proxy intend to vote on such other matters in accordance with their best judgment.
PROPOSALS OF STOCKHOLDERS FOR PRESENTATION AT THE NEXT ANNUAL MEETING OF STOCKHOLDERS
We anticipate that the next annual meeting of stockholders for the Company will be held in June 2027.
Any stockholder of record who desires to submit a proper proposal for inclusion in the proxy material related to the 2027 Annual Meeting of Stockholders pursuant to Rule 14a-8 of the Exchange Act or the Company's bylaws must do so in writing in care of Clay Smith, General Counsel and Secretary, at 8051 E. Maplewood Ave., Ste. 210, Greenwood Village, Colorado 80111 no later than December 29, 2026. In addition, our bylaws provide notice procedures for stockholders to nominate a person as a director and to propose business to be considered by stockholders at a meeting (but not for inclusion in the proxy statement). To be timely, a stockholder who intends to present nominations or a proposal at the 2027 Annual Meeting of Stockholders other than pursuant to Rule 14a-8 of the Exchange Act must provide notice in writing in care of Clay Smith, General Counsel and Secretary, at 8051 E. Maplewood Ave., Ste. 210, Greenwood Village, Colorado 80111 no earlier than January 11, 2027 and no later than February 10, 2027, provided, however, that the Company’s bylaws provide that if the date of the annual meeting has been changed by more than thirty (30) days from the date on which the previous year’s annual meeting was held, notice by the stockholder to be timely must be so received not later than the close of business on the later of one hundred twenty (120) calendar days in advance of such annual meeting or ten (10) calendar days following the date of public disclosure of the date of such meeting. If a stockholder intends to submit a proposal at the 2027 Annual Meeting of Stockholders that is not included in our corresponding proxy statement, and the stockholder fails to timely notify us of such proposal, then to the extent permitted by law, the proxies appointed by our management would be allowed to use their discretionary voting authority when the proposal is raised at the next annual meeting, without any discussion of the matter in the Proxy Statement. The stockholder must disclose, among other items, certain information related to the business to be proposed at the meeting, its beneficial ownership in the Company and whether it is acting in concert with other stockholders or interested parties. For a complete list of information that stockholders must provide, see Section 2.3 of the Company's bylaws. In addition to satisfying the deadlines in the advance notice provisions of our bylaws, a stockholder who intends to solicit proxies in support of nominees submitted under these advance notice provisions must provide the notice required under Rule 14a-19 in care of Clay Smith, General Counsel and Secretary, no later than April 11, 2027.
HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements, annual reports, or notices of internet availability of proxy materials with respect to two or more stockholders sharing the same address by delivering a single proxy statement, annual report, or notice of internet availability of proxy materials addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.
Brokers with account holders who are Company stockholders may be "householding" our proxy materials. A single proxy statement, annual report, or notice of internet availability of proxy materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you notify your broker or the Company that you no longer wish to participate in "householding."
If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement, annual report, or notice of internet availability of proxy materials, you may (1) notify your broker, (2) direct your written request to: Arq, Inc., Attn: Corporate Secretary, 8051 E. Maplewood Ave., Ste. 210, Greenwood Village, Colorado 80111, Telephone: 888-822-8617 or (3) contact our Investor Relations department by email at investors@arq.com. Stockholders who currently receive multiple copies of the proxy statement, annual report, or notice of internet availability of proxy materials at their address and would like to request "householding" of their
53

communications should contact their broker. In addition, the Company will deliver, upon written or oral request to the address or telephone number above, a separate copy of the proxy statement, annual report, or notice of internet availability of proxy materials promptly to any stockholder at a shared address to which a single copy of the documents was delivered.

1.ESTABLISHMENT, OBJECTIVES AND DURATION.
(a)Establishment of the Plan. Arq, Inc. hereby establishes an incentive compensation plan to be known as the "Arq, Inc. 2026 Omnibus Incentive Plan." The Plan permits the granting of Nonqualified Stock Options, Incentive Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Performance Stock Units, Other Stock-Based Awards and Cash-Based Awards. The Plan is effective as of June 10, 2026 (the "Effective Date"), subject to the approval of the Plan by the stockholders of the Company. Definitions of capitalized terms used in the Plan are contained in the attached Glossary, which is an integral part of the Plan.
(b)Objectives of the Plan. The objectives of the Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to Participants and to optimize the profitability and growth of the Company through incentives that are consistent with the Company’s goals and that link the personal interests of Participants to those of the Company’s stockholders. The Plan is further intended to provide flexibility to the Company in its ability to motivate, attract, and retain the services of Participants who make or are expected to make significant contributions to the Company’s success and to allow Participants to share in the success of the Company.
(c)Duration of the Plan. No Award may be granted under the Plan after the day immediately preceding the 10th anniversary of the Effective Date, or such earlier date as the Board shall determine. The Plan will remain in effect with respect to outstanding Awards until no Awards remain outstanding.
2.ADMINISTRATION OF THE PLAN.
(a)The Committee. The Plan shall be administered by the Compensation Committee of the Board or such other committee as the Board shall designate consisting of two or more members of the Board each of whom is intended to be a "non-employee director" within the meaning of Rule 16b-3 (or any successor rule) of the Exchange Act and an "independent director" under the Nasdaq Marketplace Rules or the rules of any securities exchange on which Shares are listed (such committee, the "Committee"). The members of the Committee shall be appointed from time to time by, and shall serve at the discretion of, the Board.
(b)Authority of the Committee. Subject to Applicable Laws and the provisions of the Plan (including any other powers given to the Committee hereunder), and except as otherwise provided by the Board, the Committee shall have full and final authority in its discretion to take all actions determined by the Committee to be necessary in the administration of the Plan, including discretion to:
i.select the Employees, Directors and Consultants to whom Awards may from time to time be granted hereunder;
ii.determine whether and to what extent Awards are granted hereunder;
iii.determine the size and types of Awards granted hereunder;
iv.approve forms of Award Agreement for use under the Plan;
v.determine the terms and conditions of any Award granted hereunder;
vi.establish performance goals and performance measures for any performance period, adjust performance goals or measures, or the assessment of any performance goals or measures, applicable to any Award, including to account for any unusual in nature or infrequently occurring items, and determine whether such goals or measures were satisfied;
A-1

vii.amend the terms of any outstanding Award granted under the Plan, provided that, except as otherwise provided in Section 17, no such amendment shall reduce the Exercise Price of outstanding Options or the grant price of outstanding SARs without the approval of the stockholders of the Company, and provided further, that any amendment that would materially and adversely affect the Participant’s rights under an outstanding vested Award without adequate compensation therefor shall not be made without the Participant’s written consent;
viii.construe and interpret the terms of the Plan and any Award Agreement entered into under the Plan, and to decide all questions of fact arising in its application; and
ix.take such other action, not inconsistent with the terms of the Plan, as the Committee deems appropriate.
As permitted by Applicable Laws, the Committee may delegate its authority as identified herein, including the power and authority to make Awards to Participants who are not "insiders" subject to Section 16(b) of the Exchange Act, pursuant to such conditions and limitations as the Committee may establish.
(c)Effect of Committee’s Decision. All decisions, determinations and interpretations of the Committee shall be final, binding and conclusive on all persons, including the Company, its Subsidiaries, its stockholders, Employees, Directors, Consultants and their estates and beneficiaries.
3.SHARES SUBJECT TO THE PLAN.
(a)Number of Shares Available for Grants. Subject to adjustment as provided in Section 17 hereof, the maximum number of Shares that may be issued pursuant to Awards under the Plan shall be 1,500,000 plus (i) any Shares that remain available for grant under the Prior Plans as of the date of stockholder approval of this Plan and (ii) any Shares that become available for issuance under the Plan or the Prior Plans pursuant to Section 3(b). The Shares to be issued pursuant to the Awards may be authorized but unissued Shares or treasury Shares.
(b)Availability of Shares. Any Shares subject to an Award granted under the Plan or under a Prior Plan that is subsequently canceled, forfeited, or expires prior to exercise or realization, whether in full or in part, will again be available and counted for purposes of determining the maximum number of Shares available for Awards under the Plan under Section 3(a). Notwithstanding the foregoing, Shares subject to an Award shall not be available again for issuance or delivery under the Plan if such Shares were (a) tendered or withheld in payment of the Exercise Price of an Option; (b) covered by, but not issued upon settlement of, stock-settled SARs; (c) delivered to, or withheld by, the Company to satisfy any tax withholding obligation, or (d) purchased on the open market with Option proceeds. If an Award, by its terms, may only be settled in cash, then the grant, vesting, payout, settlement, or forfeiture of such Award shall have no impact on the number of Shares available for grant under the Plan.
(c)Limitations on Awards. Subject to adjustment as provided in Section 17, the following additional limitations are imposed under the Plan:
i.Incentive Stock Options. The aggregate number of Shares that may be issued pursuant to the exercise of Incentive Stock Options granted under this Plan shall not exceed 1,500,000, which number shall be calculated and adjusted pursuant to Section 17 only to the extent that such calculation or adjustment will not affect the status of any Option intended to qualify as an Incentive Stock Option under Section 422 of the Code.
ii.Minimum Vesting Requirements. Except for Awards with respect to 5% of the Shares authorized for issuance under the Plan, all Awards granted under the Plan must be granted with a minimum vesting period of at least one year without providing for incremental vesting during such one-year period.
iii.Limit on Director Compensation. The aggregate dollar value of equity-based compensation (based on the grant date fair value) and cash compensation granted under the Plan or otherwise to any Director shall not exceed $350,000 during any calendar year; provided,
A-2

however, that in the calendar year in which a Director first joins the Board or during any calendar year in which a Director is designated as Chairman of the Board or Lead Director, the maximum aggregate dollar value of equity-based and cash compensation granted to the Director may be up to $400,000.
4.ELIGIBILITY AND PARTICIPATION.
(a)Eligibility. Persons eligible to participate in the Plan include all Employees, Directors and Consultants.
(b)Actual Participation. Subject to the provisions of the Plan, the Committee may, from time to time, select from all eligible Employees, Directors and Consultants, those to whom Awards shall be granted and shall determine the nature and amount of each Award. The Committee may establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions and to afford Participants favorable treatment under such laws; provided, however, that no Award shall be granted under any such additional terms, conditions, rules or procedures with terms or conditions which are inconsistent with the provisions of the Plan.
5.TYPES OF AWARDS.
(a)Type of Awards. Awards under the Plan may be in the form of Options (both Nonqualified Stock Options and Incentive Stock Options), Stock Appreciation Rights (SARs), Restricted Stock, Restricted Stock Units, Performance Stock Units, Other Stock-Based Awards and Cash-Based Awards.
(b)Designation of Award. Each Award shall be designated in the Award Agreement.
6.OPTIONS.
(a)Grant of Options. Subject to the terms and provisions of the Plan, Options may be granted to Participants in such number and upon such terms, and at any time and from time to time, as shall be determined by the Committee. Notwithstanding the preceding sentence, Incentive Stock Options may be granted only to eligible Employees.
(b)Award Agreement. Each Option grant shall be evidenced by an Award Agreement that shall specify the Exercise Price, the duration of the Option, the number of Shares to which the Option pertains, and such other provisions as the Committee shall determine including the Option vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash, Shares, or other consideration) upon settlement of the Award, and payment contingencies. The Award Agreement also shall specify whether the Option is intended to be an Incentive Stock Option or a Nonqualified Stock Option. Options that are intended to be Incentive Stock Options shall be subject to the limitations set forth in Section 422 of the Code.
(c)Exercise Price. Except for Options adjusted pursuant to Section 17 herein, and replacement Options granted in connection with a merger, acquisition, reorganization or similar transaction, the Exercise Price for each grant of an Option shall not be less than 100% of the Fair Market Value of a Share on the date the Option is granted.
i.Notwithstanding the above, in the case of an Incentive Stock Option granted to a Participant who, at the time the Option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Subsidiary, the Exercise Price for each grant of an Option shall not be less than 110% of the Fair Market Value of a Share on the date the Option is granted.
ii.In addition, the aggregate Fair Market Value, as of the date of grant, of the Shares with respect to which an Incentive Stock Option first becomes exercisable during any calendar year may not exceed $100,000. For purposes of this $100,000 limit, the Participant’s Incentive Stock Options under this Plan and all other plans maintained by the Company and its Subsidiaries shall be aggregated. To the extent any Incentive Stock Option would exceed this $100,000 limit, the Incentive Stock Option shall afterwards be treated as a Nonqualified Stock Option for all purposes.
A-3

(d)Term of Options. The term of an Option granted under the Plan shall be determined by the Committee, in its sole discretion; provided, however, that such term shall not exceed 10 years. However, in the case of an Incentive Stock Option granted to a Participant who, at the time the Option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Subsidiary, the term of the Incentive Stock Option shall be five years from the date of grant thereof or such shorter term as may be provided in the Award Agreement.
(e)Exercise of Options. Options granted under this Section 6 shall be exercisable at such times and be subject to such restrictions and conditions as set forth in the Award Agreement and as the Committee shall in each instance approve, subject to the minimum vesting requirements in Section 3(c)(ii). Such restrictions and conditions need not be the same for each grant or for each Participant.
(f)Payments. Options granted under this Section 6 shall be exercised by the delivery of a written notice to the Company, setting forth the number of Shares with respect to which the Option is to be exercised and specifying the method of the Exercise Price. The Exercise Price of an Option shall be payable to the Company: (i) in cash or its equivalent, (ii) by tendering (either actually or constructively by attestation) Shares having an aggregate Fair Market Value at the time of exercise equal to the Exercise Price, (iii) in any other manner then permitted by the Committee, including a cashless exercise, or (iv) by a combination of any of the permitted methods of payment. The Committee may limit any method of payment, other than that specified under (i), for administrative convenience, to comply with Applicable Laws or otherwise.
(g)Restrictions on Share Transferability. The Committee may impose such restrictions on any Shares acquired pursuant to the exercise of an Option granted under this Section 6 as it may deem advisable, including restrictions under applicable federal securities laws, under the requirements of any stock exchange or market upon which such Shares are then listed and/or traded, and under any blue sky or state securities laws applicable to such Shares.
(h)Termination of Employment or Service. Each Participant’s Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant’s employment or, if the Participant is a Director or Consultant, service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all Options, and may reflect distinctions based on the reasons for termination of employment or service.
7.STOCK APPRECIATION RIGHTS.
(a)Grant of SARs. Subject to the terms and provisions of the Plan, SARs may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.
(b)Award Agreement. Each SAR grant shall be evidenced by an Award Agreement that shall specify the grant price, the term of the SAR, and such other provisions as the Committee shall determine.
(c)Grant Price. The grant price of a SAR shall not be less than 100% of the Fair Market Value of a Share on the date of grant of the SAR; provided, however, that this limitation shall not apply to Awards that are adjusted pursuant to Section 17 herein.
(d)Term of SARs. The term of an SAR granted under the Plan shall be determined by the Committee, in its sole discretion; provided, however, that such term shall not exceed 10 years.
(e)Exercise of SARs. SARs may be exercised upon whatever terms and conditions the Committee, in its sole discretion, imposes upon them and sets forth in the Award Agreement, subject to the minimum vesting requirements in Section 3(c)(ii). Such terms and conditions need not be the same for each grant or for each Participant.
(f)Payment of SAR Amount. Upon exercise of an SAR, a Participant shall be entitled to receive payment from the Company in an amount determined by multiplying:
A-4

i.the difference between the Fair Market Value of a Share on the date of exercise over the grant price; by
ii.the number of Shares with respect to which the SAR is exercised.
At the discretion of the Committee, the payment upon SAR exercise may be in cash, in Shares of equivalent value, or in some combination thereof.
(g)Termination of Employment or Service. Each SAR Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the SAR following termination of the Participant’s employment or, if the Participant is a Director or Consultant, service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all SARs, and may reflect distinctions based on the reasons for termination of employment or service.
8.RESTRICTED STOCK.
(a)Grant of Restricted Stock. Subject to the terms and provisions of the Plan, Restricted Stock may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.
(b)Award Agreement. Each Restricted Stock grant shall be evidenced by an Award Agreement that shall specify the Period(s) of Restriction, the number of Shares of Restricted Stock granted, and such other provisions as the Committee shall determine.
(c)Period of Restriction and Other Restrictions. The Period of Restriction applicable to an Award of Restricted Stock may, at the discretion of the Committee, lapse on a pro-rated, graded, or cliff basis (as specified in an Award Agreement), subject to the minimum vesting requirements in Section 3(c)(ii). The Committee shall impose such other conditions and/or restrictions on any Shares of Restricted Stock granted pursuant to the Plan as it may deem advisable including a requirement that Participants pay a stipulated purchase price for each Share of Restricted Stock, a requirement that the issuance of Shares of Restricted Stock be delayed, restrictions based upon the achievement of specific performance goals, additional time-based restrictions, and/or restrictions under Applicable Laws or under the requirements of any stock exchange or market upon which such Shares are listed or traded, or holding requirements or sale restrictions placed on the Shares by the Company upon vesting of such Restricted Stock. The Company may retain in its custody any certificate evidencing the Shares of Restricted Stock and place thereon a legend and institute stop-transfer orders on such Shares, and the Participant shall be obligated to sign any stock power requested by the Company relating to the Shares to give effect to the forfeiture provisions of the Restricted Stock.
(d)Removal of Restrictions. Subject to Applicable Laws, Restricted Stock shall become freely transferable by the Participant after the last day of the Period of Restriction applicable thereto. Once Restricted Stock is released from the restrictions, the Participant shall be entitled to receive a certificate or book entry on the Company’s records evidencing the Shares.
(e)Voting Rights. Unless otherwise determined by the Committee and set forth in a Participant’s Award Agreement, to the extent permitted or required by Applicable Laws, as determined by the Committee, Participants holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares during the Period of Restriction.
(f)Dividends and Other Distributions. Regular cash Dividends paid with respect to the Shares of Restricted Stock will be subject to the same restrictions on transferability and vesting as the Restricted Stock with respect to which they were paid, and such Dividends will be paid within 30 days following the full vesting of the Shares of Restricted Stock with respect to which such distributions were made.
(g)Termination of Employment or Service. Each Award Agreement shall set forth the extent to which the Participant shall have the right to retain unvested Restricted Stock following termination of the Participant’s employment or, if the Participant is a Director or Consultant, service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need
A-5

not be uniform among all Awards of Restricted Stock, and may reflect distinctions based on the reasons for termination of employment or service.
9.RESTRICTED STOCK UNITS.
(a)Grant of Restricted Stock Units. Subject to the terms and provisions of the Plan, Restricted Stock Units may be granted to Participants in such amounts and upon such terms, and at any time and from time to time, as shall be determined by the Committee.
(b)Award Agreement. Each grant of Restricted Stock Units shall be evidenced by an Award Agreement that shall specify the applicable Period of Restriction, the number of Restricted Stock Units granted, and such other provisions as the Committee shall determine.
(c)Period of Restriction. The Period of Restriction subject to an Award of Restricted Stock Units may, at the discretion of the Committee, lapse on a pro-rated, graded, or cliff basis, subject to the minimum vesting requirements in Section 3(c)(ii). The Committee shall impose such other conditions and/or restrictions on any Restricted Stock Units granted pursuant to the Plan as it may deem advisable, including a requirement that the issuance of Shares upon vesting of the Restricted Stock Units be delayed, restrictions based upon the achievement of specific performance goals, additional time-based restrictions, and/or restrictions under Applicable Laws or under the requirements of any stock exchange or market upon which such Shares are listed or traded, or holding requirements or sale restrictions placed on the Shares by the Company upon vesting of such Restricted Stock Units.
(d)Form and Timing of Payment. Except as otherwise provided in Section 17 herein or a Participant’s Award Agreement, payment of Restricted Stock Units shall be made at a specified settlement date that shall not be earlier than the last day of the Period of Restriction.

The Committee may provide that settlement of Restricted Stock Units shall be deferred, on a mandatory basis or at the election of the Participant, in compliance with Applicable Laws, including Section 409A.
(e)Voting Rights. A Participant shall have no voting rights with respect to any Restricted Stock Units granted hereunder.
(f)Termination of Employment or Service. Each Award Agreement shall set forth the extent to which the Participant shall have the right to receive a payout respecting an Award of Restricted Stock Units following termination of the Participant’s employment or, if the Participant is a Director or Consultant, service with the Company and its Subsidiaries. Such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all Restricted Stock Units, and may reflect distinctions based on the reasons for termination of employment or service.

(c)Form and Timing of Payment. Except as otherwise provided in Section 17 herein or a Participant’s Award Agreement, payment of Performance Stock Units shall be made at a specified settlement date. The Committee, in its sole discretion, may pay earned Performance Stock Units by delivery of Shares or by payment in cash of an amount equal to the Fair Market Value of such Shares (or a combination thereof). The Committee may provide that settlement of Performance Stock Units shall be deferred, on a mandatory basis or at the election of the Participant, in compliance with Applicable Laws, including Section 409A.

14.TRANSFERABILITY OF AWARDS.

such as a merger, consolidation, any reorganization (whether or not such reorganization comes within the definition of such term in Section 368 of the Code) or any partial or complete liquidation of the Company, the Company, in its sole discretion, may cause there to be made an equitable adjustment to the number and kind shares that may be issued under the Plan, or to any individual under the Plan, and to the number and kind of shares or other property subject to and the Exercise Price (if applicable) of any then outstanding Awards, and such adjustment shall be conclusive and binding for all purposes of the Plan.

ii.any Period of Restriction or other restriction imposed on Restricted Stock, Restricted Stock Units, and Other Stock-Based Awards shall lapse unless such Awards are assumed, converted or replaced by the continuing entity; provided, however, that in the event of a Participant’s termination of employment without Cause or termination with Good Reason within 12 months following consummation of a Change in Control, the Period of Restriction on any replacement awards shall lapse upon such termination; and
iii.any and all Performance Stock Units and other Awards (if performance-based) shall vest (with the level of performance determined by the Committee) unless such Awards are assumed, converted or replaced by the continuing entity; provided, however, that in the event of a Participant’s termination of employment without Cause or termination with Good Reason within 12 months following the consummation of a Change in Control, any replacement awards shall fully vest upon such termination (with the level of performance determined by the Committee); provided, further, that the performance measures applicable to any assumed, converted or replaced award may, in the Committee’s discretion, (A) be determined based on performance achieved as of the date of the Change in Control, if determinable, (B) be determined based on a specified level of performance as of the date of the Change in Control, or (C) may be continued or adjusted to reflect such Change in Control.
(b)Cash-Out and Termination of Awards. The Committee may, in its sole discretion, provide that:
i.all outstanding Awards shall be terminated upon the occurrence of a Change in Control and that each Participant shall receive, with respect to each Share subject to such Award, an amount in cash equal to the excess of the Fair Market Value of a Share immediately prior to the occurrence of the Change in Control over the Option Exercise Price or the SAR grant price, if applicable; and
ii.Options and SARs outstanding as of the date of the Change in Control may be cancelled and terminated without payment therefore if the Fair Market Value of a Share as of the date of the Change in Control is equal to or less than the Option Exercise Price or the SAR grant price.
(c)Subsidiary Disposition. The Committee shall have the authority, exercisable either in advance of any actual or anticipated Subsidiary Disposition or at the time of an actual Subsidiary Disposition and either at the time of the grant of an Award or at any time while an Award remains outstanding, to provide for the automatic full vesting and exercisability of one or more outstanding unvested Awards under the Plan and the termination of restrictions on transfer and repurchase or forfeiture rights on such Awards, in connection with a Subsidiary Disposition, but only with respect to those Participants who
A-9

are at the time engaged primarily in Continuous Service with the Subsidiary involved in such Subsidiary Disposition. The Committee also shall have the authority to condition any such Award vesting and exercisability or release from such limitations upon the subsequent termination of the affected Participant’s Continuous Service with that Subsidiary within a specified period following the effective date of the Subsidiary Disposition. The Committee may provide that any Awards so vested or released from such limitations in connection with a Subsidiary Disposition, shall remain fully exercisable until the expiration or sooner termination of the Award.
19.AMENDMENT, SUSPENSION OR TERMINATION OF THE PLAN.

The Committee may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including the events described in Section 18 hereof) affecting the Company or the financial statements of the Company or of changes in Applicable Laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan.
(c)Awards Previously Granted. No termination, amendment or modification of the Plan or of any Award shall adversely affect in any material way any Award previously granted under the Plan without the written consent of the Participant holding such Award, unless such termination, modification or amendment is compensated by adequate consideration or required by Applicable Laws and except as otherwise provided herein.
(d)No Repricing. Except for adjustments made pursuant to Section 17, no amendment shall reduce the Exercise Price of outstanding Options or the grant price of outstanding SARs, nor may any outstanding Options or outstanding SARs be surrendered to the Company as consideration for (i) the grant of new Options or SARs with a lower Exercise Price or grant price or (ii) for cash or a new Award with a lower (or no) Exercise Price, in each case, without the approval of the stockholders of the Company.
20.RESERVATION OF SHARES.
(a)The Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.
(b)The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.
21.RIGHTS OF PARTICIPANTS.
(a)Continued Service.

A-10

purchase, merger, consolidation, or other event, or a sale or disposition of all or substantially all of the business and/or assets of the Company and references to the “Company” herein and in any Award Agreements shall be deemed to refer to such successors.
23.LEGAL CONSTRUCTION.
(a)Interpretation. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular and the singular shall include the plural. Any reference in the Plan to a Section of the Plan either in the Plan or any Award Agreement or to an agreement, act, code, rule or regulation shall be deemed to refer to such Section of the Plan, agreement, act, code, section, rule or regulation, as may be amended from time to time, or to any successor Section of the Plan, act, code, section, rule or regulation. All references to "including" shall be construed as meaning "including without limitation."
(b)Severability. In the event any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

(d)Governing Law. To the extent not preempted by federal law, the Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the State of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan to the substantive law of another jurisdiction.
(e)Non-Exclusive Plan. Neither the adoption of the Plan by the Board nor its submission to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board or a committee thereof to adopt such other incentive arrangements as it may deem desirable.
(f)Code Section 409A Compliance. To the extent applicable, it is intended that this Plan and any Awards granted hereunder be exempt from, or comply, with the requirements of Section 409A. Any provision that would cause the Plan or any Award granted hereunder to fail to satisfy Section 409A shall have no force or effect until amended to comply with Section 409A, which amendment may be retroactive to the extent permitted by Section 409A. Notwithstanding anything in this Plan or Award granted hereunder to the contrary, in no event will the Committee provide for the deferral of settlement or vesting of any Award, on a mandatory basis or Participant elective basis, unless such deferral is documented in writing and administered in compliance with Section 409A. In no event shall the number, kinds, or Exercise Price of any Award granted hereunder be modified or extended if such modification or extension would result in a violation of Section 409A.
24.CLAWBACK.
(a)Mandatory Clawback. Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy that the Company adopts or is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law.
(b)Permissive Clawback. All Awards under the Plan will be subject to recoupment upon the occurrence of a Forfeiture Event with respect to a Participant. Upon the occurrence of a Forfeiture Event with respect to a Participant, the Committee may, but is not obligated to, require recoupment from such Participant of an amount up to the sum of all Awards granted to, held by, earned by, or settled with respect to, such Participant during the fiscal year the misconduct occurred. The Committee may effect this recoupment using any other method it deems appropriate in its sole discretion, including cancelling outstanding Awards and requiring that the Participant pay to the Company an amount up to (but not in
A-11

excess of) the lesser of (i) the value of such previously settled Awards as of the date such Awards were settled or (ii) the value of such previously settled Awards as of the last trading day prior to the date on which the Company makes a demand for payment. Unless otherwise determined by the Committee, any amount payable by such Participant under this Section 24(b) shall be paid within 60 days of receipt from the Company of written notice requiring payment. Notwithstanding the foregoing, this Section 24(b) shall not apply to any Award following the effective time of a Change in Control of the Company.
(c)Other. In addition to the above, the Committee may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Committee determines necessary or appropriate, including a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of misconduct. No recovery of compensation under this Section 24 will be an event giving rise to a right to resign for “good reason” or be deemed a "constructive termination" (or any similar term) as such terms are used in any agreement between any Participant and the Company. Except as otherwise provided by law or under the terms of a specific clawback policy, all determinations regarding the applicability of these provisions shall be in the discretion of the Committee.
