**What does it mean if I receive more than one Notice?**

You may receive more than one Notice, more than one e-mail or multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you may receive a separate Notice, a separate e-mail or a separate voting instruction card for each brokerage account in which you hold shares. If you are a stockholder of record and your shares are registered in more than one name, you may receive more than one Notice, more than one e-mail or more than one proxy card. To vote all of your shares by proxy, you must complete, sign, date and return each proxy card and voting instruction card that you receive and vote over the Internet the shares represented by each Notice that you receive (unless you have requested and received a proxy card or voting instruction card for the shares represented by one or more of those Notices).

------

**May I change my vote?**

Yes. You may revoke your proxy at any time before it is voted at the Annual Meeting. To change your vote, if you are a stockholder of record, you may submit another later dated proxy by telephone, Internet or mail or by voting your shares electronically on the virtual meeting platform at the Annual Meeting (your attendance at the Annual Meeting will not, by itself, revoke your proxy; you must vote in person at the Annual Meeting to revoke your proxy). If you are a beneficial owner and your shares are held in street name, you may change your vote by submitting new voting instructions to your bank, broker, trustee or nominee, or if you have obtained a legal proxy from such entity giving you the right to vote your shares, you may change your vote by attending the Annual Meeting and voting electronically on the virtual meeting platform;

**What vote is required to elect directors and approve the other matters described in this proxy statement?**

The director nominees must receive the affirmative vote of a plurality of the votes cast in person or by proxy at the Annual Meeting. Abstentions and broker non-votes will have no effect on the outcome of the election of directors.

For the ratification of the retention of BDO as our independent registered public accounting firm (Proposal No. 2), the affirmative vote of the holders of a majority of the shares present in person or by proxy at the Annual Meeting and entitled to vote. Accordingly, abstentions will have the effect of a negative vote on Proposal No. 2. Absent specific instructions on Proposal No. 2, brokers are permitted to exercise voting discretion with respect to such proposal. For additional information about broker non-votes see "How do I vote if my bank or broker holds my shares in 'street name'?"

For approving the Officer Exculpation Amendment proposal, the affirmative vote of at least a majority of our outstanding voting shares is required. Abstentions will count as present and entitled to vote for purposes of this proposal and will have the effect of a vote against this proposal. Broker non-votes will have the effect of a vote against this proposal.

**What is the difference between holding shares as a stockholder of record and as a beneficial owner?**

If your shares are registered in your name on the Company's books and records or with our transfer agent, you are the "stockholder of record" of those shares, and this proxy statement and accompanying materials have been provided directly to you by the Company. On the other hand, if you purchased your shares through a brokerage or other financial intermediary, the brokerage or other financial intermediary will automatically put your shares into "street name" which means that the brokerage or other financial intermediary will hold your shares in its name or another nominee's name and not in your name, but will keep records showing you as the "beneficial owner." If you hold shares beneficially in street name, this proxy statement and accompanying materials have been forwarded to you by your broker, bank or other holder of record.

**How do I vote if my bank or broker holds my shares in "street name"?**

If you hold your shares in "street name" through a bank, broker or other nominee, such bank, broker or nominee will vote those shares in accordance with your instructions. To so instruct your bank, broker or nominee, you should refer to the information provided to you by such entity. Without instructions from you, a bank, broker or nominee will be permitted to exercise its own voting discretion with respect to so-called routine matters (Proposal No. 2 (ratification of auditors)), but will not be permitted to exercise voting discretion with respect to non-routine matters (Proposal No. 1 (director elections) and Proposal No. 3 (Officer Exculpation Amendment)). Thus, if you do not give your bank, broker or nominee specific instructions with respect to Proposal No. 2, your shares will be voted in such entity's discretion. If you do not give your bank, broker or nominee specific instructions with respect to Proposal No. 1 or Proposal No. 3, your shares will not be voted on such proposals. This is called a "broker non-vote." Shares represented by such broker non-votes will be counted in determining whether there is a quorum. We urge you to promptly provide your bank, broker or nominee with appropriate voting instructions so that all your shares may be voted at the Annual Meeting.

------

**How will the votes be counted at the Annual Meeting?**

The votes will be counted by the inspector of election appointed for the Annual Meeting.

**How will the Company announce the voting results?**

The Company will report the final results of the voting at the Annual Meeting in a filing with the Securities and Exchange Commission ("SEC") on a Current Report on Form 8-K.

**Who pays for the Company's solicitation of proxies?**

The Board is soliciting your proxy to vote your shares of common stock at our Annual Meeting. We will bear the cost of soliciting proxies on behalf of the Company, including preparing, printing and mailing this proxy statement. Proxies may be solicited personally, by mail, email or by telephone by certain of our directors, officers, employees or representatives. Our directors and employees will not be paid any additional compensation for soliciting proxies. We will reimburse brokerage houses, banks, custodians and other nominees and fiduciaries for out-of-pocket expenses incurred in forwarding our proxy solicitation materials.

**What is "householding" and how does it work?**

Under the rules adopted by the SEC, we may deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as "householding" and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of these documents was delivered. If you prefer to receive separate copies of the Notice, proxy statement or annual report, contact Broadridge Financial Solutions, Inc. by calling 1-800-542-1061 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

In addition, if you currently are a stockholder who shares an address with another stockholder and would like to receive only one copy of future notices and proxy materials for your household, you may notify your broker if your shares are held in a brokerage account or you may notify us if you hold registered shares. Registered stockholders may notify us by contacting Broadridge Financial Solutions, Inc. at the above telephone number or address or sending a written request to AdTheorent Holding Company, Inc. 330 Hudson Street, 13th Floor New York, New York 10013, Attention: Secretary.

**PROPOSAL ONE**

**ELECTION OF DIRECTORS**

The Company has three classes of directors. The term of each directorship is three years so that one class of directors is elected each year. All directors are elected for three-year terms and until their successors are duly elected and qualified.

Upon the recommendation of our Nominating and Corporate Governance Committee, the Board has nominated Vineet Mehra and Zia Uddin to stand for re-election to the Board and Shuangxiu Yu to stand for election as Class II directors for a three-year term ending at the annual meeting of stockholders in 2026 or until their successors, if any, are elected or appointed.

Our Second Amended and Restated Certificate of Incorporation ("Charter") and Amended and Restated Bylaws ("Bylaws") provide for the annual election of directors. As described below under "Certain Relationships and Related Person Transactions," pursuant to our Stockholder's Agreement, H.I.G. currently has the right to nominate four (4) directors to our Board and the Sponsor currently has the right to nominate one (1) director to our Board. Richard Boghosian was one of the original directors nominated to the Board by H.I.G. pursuant to the Stockholders' Agreement. Mr. Boghosian will not continue on our board upon the expiration of his term. Pursuant to the Stockholders' Agreement, H.I.G. has asked the Nominating Committee to nominate Ms. Yu to the seat being vacated by Mr. Boghosian upon the expiration of his term. Mr. Uddin was nominated by the Sponsor. Each director nominee must receive the affirmative vote of a plurality of the votes cast in person or by proxy at the Annual Meeting. Unless contrary instructions are given, the shares represented by your proxy will be voted FOR the election of all director nominees.

The Board of Directors has no reason to believe that any of the nominees will not serve if elected. However, if any nominee becomes unavailable to serve as a director, the Company representatives named on the proxy card will have discretion and authority to vote for another nominee proposed by our Board unless you submit a proxy withholding your vote from the nominee being substituted. Alternatively, our Board may reduce the number of directors to be elected at the Annual Meeting.

Biographical information relating to each of the director nominees is set forth below under "Management"

and incorporated by reference herein.

**THE BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE ELECTION OF EACH OF THE DIRECTOR NOMINEES NAMED IN THIS PROXY STATEMENT AS CLASS II DIRECTORS.**

**Board Composition**

Our Board directs our business and affairs, as provided by Delaware law, and conducts its business through meetings of the Board and its standing committees.

Our Board consists of nine members. Eric Tencer serves as Chairperson of our Board. The primary responsibilities of our Board will be to provide oversight, strategic guidance, counseling and direction to our management team. Our Board meets on a regular basis and additionally as required. In 2022, our Board met six times, our Audit Committee met seven times, our Compensation Committee met five times, and our Nominating and Corporate Governance Committee met five times.

Our Charter provides that our Board shall be divided into three classes with only one class of directors being elected in each year and each class (except for those directors appointed prior to our first annual general meeting) serving a three-year term. The term of office of the first class of directors, consisting of Ben Tatta, John Black and Danielle Qi, will expire at the 2025 annual general meeting. The term of the second class of directors, consisting of Vineet Mehra, Richard Boghosian, and Zia Uddin, will expire at this Annual Meeting. The term of office of the third class of directors, consisting of Kihara Kiarie, Eric Tencer and James Lawson, will expire at the 2024 annual general meeting.

**Family Relationships**

There are no family relationships between any of our executive officers and directors.

**Independence of Directors**

The Nasdaq listing standards generally define an "independent director" as a person, other than an executive officer of a company or any other individual having a relationship which, in the opinion of the issuer's Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. We have determined that Ben Tatta, John Black, Danielle Qi, Vineet Mehra, Shuangxiu Yu, Zia Uddin, Kihara Kiarie and Eric Tencer are independent directors of the Company. The Company's independent directors shall have regularly scheduled meetings at which only independent directors are present.

**Business Combination**

On December 22, 2021 (the "Closing Date"), MCAP Acquisition Corporation ("MCAP"), now known as AdTheorent Holding Company, Inc., consummated the previously announced business combination pursuant to that certain Business Combination Agreement, dated as of July 27, 2021 (as amended, restated, supplemented or otherwise modified, the "Business Combination Agreement"), by and among MCAP, GRNT Merger Sub 1 LLC, a Delaware limited liability company ("Merger Sub 1"), GRNT Merger Sub 2 LLC, a Delaware limited liability company ("Merger Sub 2"), GRNT Merger Sub 3 LLC, a Delaware limited liability company ("Merger Sub 3"), GRNT Merger Sub 4 LLC, a Delaware limited liability company ("Merger Sub 4" and, together with Merger Sub 1, Merger Sub 2 and Merger Sub 3, the "Merger Sub Entities"), H.I.G. Growth—AdTheorent Intermediate, LLC, a Delaware limited liability company (the "Blocker"), H.I.G. Growth—AdTheorent, LLC, a Delaware limited liability company, and AdTheorent Holding Company, LLC, a Delaware limited liability company ("Legacy AdTheorent"). Pursuant to the terms of the Business Combination Agreement, Legacy AdTheorent, the Blocker and the Merger Sub Entities engaged in a series of four mergers, which resulted in Legacy AdTheorent becoming a wholly owned subsidiary of MCAP (the "Business Combination'). On the Closing Date, and in connection with the closing of the Business Combination, MCAP changed its name to AdTheorent Holding Company, Inc.

Our current Board was appointed and committees were established in connection with the Business Combination in December 2021. Following the Business Combination, our Board and committees did not hold any meetings in 2021. Our directors are encouraged to attend all annual and special meetings of our stockholders.

**Board Leadership Structure and Role in Risk Oversight**

Our Board recognizes that the leadership structure and combination or separation of the Chief Executive Officer and Chairman roles is driven by our needs at any point in time. As a result, no policy exists requiring combination or separation of leadership roles, and our governing documents do not mandate a particular structure. This allows our Board the flexibility to establish the most appropriate structure for the Company any given time.

Our Board oversees the risk management activities designed and implemented by our management. Our Board does not have a standing risk management committee, but rather anticipates executing its oversight responsibility both directly and through its standing committees. Our Board also will consider specific risk topics, including risks associated with our strategic initiatives, business plans, and capital structure. Our management, including our executive officers, are primarily responsible for managing the risks associated with operation and business of the Company and providing appropriate updates to the Board and the Audit Committee. Our Board has delegated to the Audit Committee oversight of our risk management process, and our other board committees also consider risks as they perform their respective committee responsibilities. The scope of each committee's risk oversight responsibility is set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The Audit Committee reviews our policies and guidelines with respect to risk assessment and risk management. The Audit Committee oversees our major financial risk exposures, including related to internal controls and cybersecurity, as well as the steps management has taken to monitor and control those exposures. This review includes regular assessments of the Company's disclosure controls and procedures to assure that current practices account for material risks facing the Company. The Audit Committee and the management team meet quarterly, and more frequently as needed, to assess the Company's risk environment, its response to present risks, and its planned responses to future and anticipated risks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The Compensation Committee considers risk issues when establishing and administering our compensation program for executive officers and other key personnel. As part of its risk assessments, the Compensation Committee consults with Aon, an independent compensation consulting firm, to identify risks that may be associated with the Company's compensation programs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The Nominating and Corporate Governance Committee oversees matters relating to the composition and organization of the Board and advises the Board on how its effectiveness can be improved by changes in its composition and organization.

All board committees will report to our Board as appropriate, including, but not limited to, when a matter rises to the level of a material or enterprise risk.

**Board Committees of the Company's Board of Directors**

Our Board has established an Audit Committee, a Nominating and Corporate Governance Committee and a Compensation Committee. In addition, from time to time, special committees may be established under the direction of our Board when necessary to address specific issues. Copies of each board committee's charter are posted on our website.

Each member of the Audit Committee is financially literate, and our Board has determined that Kihara Kiarie qualifies as an "Audit Committee financial expert" as defined in applicable SEC rules.

Our Board has adopted an Audit Committee charter, which details the principal functions of the Audit Committee, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the appointment, compensation, retention, replacement, and oversight of the work of the independent auditors and any other independent registered public accounting firm engaged by the Company;

------

Under the Nasdaq Global Market listing standards and applicable SEC rules, our Compensation Committee must consist of all independent members. Ben Tatta and Eric Tencer meet the independent director standard under the Nasdaq Global Market listing standards, and Eric Tencer will serve as chairperson of the Compensation Committee.

Our Board has adopted a Compensation Committee charter, which details the principal functions of the Compensation Committee, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer's compensation, evaluating our Chief Executive Officer's performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation;

The charter also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by the Nasdaq Global Market and the SEC.

To assist the Compensation Committee in meeting its responsibilities, the committee engaged Aon as its independent outside compensation consultant to regularly provide executive compensation market analysis and insight, with respect to our executive officers. Aon only provides services to the Compensation Committee with respect to executive and director compensation and does not provide any other services to the company. The Compensation Committee has reviewed its relationship with Aon in light of the independence factors set forth in

------

applicable Nasdaq rules and concluded that its retention of Aon as its compensation consultant does not raise any conflict.

**Board's and Management's Role in Oversight of Environmental, Social and Governance Matters**

We believe that a sustainable business strategy that integrates environmental, social and governance ("ESG") considerations is important to creating long-term value for our stockholders and other stakeholders. We have a long history of integrating ESG considerations into our mission, business strategy, and operations, and considering the impact we have on our communities. We are focused on addressing these issues, both risks and opportunities, through our corporate strategy. By operating our advertising platforms in a responsible manner, engaging and developing our diverse workforce, and reducing our environmental impact by operating efficiently, we aim to provide more sustainable products and services that deliver long-term value for our clients, employees, communities, investors, and other stakeholders.

Since the Company's last annual meeting of stockholders on May 25, 2022, we have taken several important steps to advance our ESG strategy, including establishing an internal steering committee comprised of Board and Management members to lead the development and implementation of our ESG strategy and program ("ESG Steering Committee"). We have also evaluated our core ESG priorities and identified important operational and strategic opportunities which allow AdTheorent to provide important leadership in the programmatic advertising industry, including but not limited to the following areas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•AdTheorent's privacy-forward core digital ad-targeting methods and processes which are premised on statistics and machine learning to score advertising impressions, rather than exploitative user profiling practices that encroach on user privacy rights but are prevalent in digital marketing and advertising.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•AdTheorent's approach to supply path optimization is designed for efficiency in terms of both cost and infrastructure usage, leveraging a multi-pronged approach to ensure that our programmatic supply is efficient. We work directly with our over 20 supply side platform partners to ensure that any inventory sent to our demand side platforms generally matches our demand. For example, we throttle down international inventory in countries where our presence is lighter, as well as certain creative sizes that we do not run against. Additionally, we continuously analyze signals in the bid request that indicate whether the impression opportunity being sent is directly from the publisher, or whether that impression opportunity is going through multiple different intermediaries. Our machine learning models evaluate on an ongoing basis the optimal and most efficient path to an impression, ultimately ensuring that we are only delivering impressions that are most likely to lead to a client's business outcome, using the minimum infrastructure footprint necessary for the job.

**ESG Leadership & Oversight**

Both the Board and Management are actively engaged in the Company's ESG strategy. The Board has embraced the responsibility for overseeing our ESG programs and has had robust discussions covering a variety of ESG issues throughout the past year.

Earlier this year we formalized our internal ESG Steering Committee. This committee consists of senior leaders across the organization representing key business areas, including legal, marketing, human resources and others. The ESG Steering Committee is responsible for developing and overseeing the implementation of AdTheorent's ESG strategy and related programs, and for providing regular updates to Management and the Board of Directors.

We believe that integrating relevant ESG considerations into our long-term business strategy is important to delivering on our commitments to our stakeholders. We will continue to engage with our investors and other stakeholders to understand their ESG priorities, and we welcome stockholder perspectives and feedback on our ESG strategy.

**EXECUTIVE COMPENSATION**

As our needs evolve, we intend to continue to evaluate our compensation philosophy and programs.

Equity Compensation

Prior to the Business Combination, Legacy AdTheorent from time to time granted equity awards, in the form of options and restricted interest units, to its named executive officers, which are subject to time vesting conditions based on each of the named executive officer's continued service with Legacy AdTheorent or the attainment of performance goals. As of December 31, 2022, each of the named executive officers held outstanding options to purchase shares of our Common Stock and other awards, as set forth in the "Outstanding Equity Awards Table" below. The material terms regarding each equity award in the "Outstanding Equity Awards Table," including the vesting schedule, are described in the corresponding footnotes. The award of restricted incentive units granted to Mr. Lawson on July 28, 2021 has a time-based vesting schedule, with 50% of the restricted interest units vesting on July 1, 2022 and the remaining 25% of these restricted interest units vest in three equal quarterly installments on January 1, 2023, April 1, 2023 and July 1, 2023, such that the restricted interest units will be fully vested on July 1, 2023.

On March 11, 2022, our Board of Directors approved the first annual equity incentive grants under the 2021 Plan. The Committee granted 292,697 RSUs and 292,697 performance-based units ("PSUs") to James Lawson, 47,564 RSUs and 47,563 PSUs to Charles Jordan, and 58,540 RSUs and 58,539 PSUs to William Todd.

The RSUs granted to each of Messrs. Lawson, Todd and Jordan will vest 25% annually over the four years from January 1, 2022, subject to continued employment on such vesting dates. Upon his resignation, Mr. Jordan forfeited the remaining 75% unvested RSUs of 35,673.

50% of the PSUs granted to each of Mr. Lawson and Mr. Jordan would have been earned based on the achievement by the Company of certain revenue milestones during the period of January 1, 2022 through December 31, 2022 (the "Performance Period"). The remaining 50% of the PSUs granted to each of Mr. Lawson and Mr.

------

Jordan would have been earned based on achievement by the Company of certain Adjusted EBITDA milestones during the Performance Period.

If earned, the PSUs would vest, subject to continuous employment, according to the following schedule: (i) 25% will vest on the date performance achievement is determined by the Compensation Committee, which will be no later than March 31, 2023 and (ii) the remainder of the earned PSUs would vest in three equal installments on the first, second and third anniversaries of the last day of the Performance Period. In the event of a qualifying termination of employment, all earned but unvested PSUs would continue to vest in accordance with the vesting schedule described above. A qualifying termination of employment includes the executive's termination of employment by the Company without "cause" (each such term is defined in the Plan), a termination due to the executive's death or disability, or, in the case of Mr. Lawson, on a termination by the executive for "good reason" (as such term is defined in Mr. Lawson's employment agreement).

The Compensation Committee determined that the defined milestones had not been achieved, and the PSUs granted on March 11, 2022 were cancelled as of December 31, 2022.

Benefits and Perquisites

We provide benefits to our named executive officers on the same basis as provided to all of its employees, including health, dental and vision insurance; life insurance; accidental death and dismemberment insurance; short-and long-term disability insurance; and a tax-qualified Section 401(k) plan. We do not maintain any executive-specific benefit or perquisite programs.

Retirement Benefits

Our employees, including named executive officers participate in a tax-qualified Section 401(k) plan. We make a safe harbor matching contribution equal to 100% of a participant's salary deferrals that do not exceed 3% of the participant's compensation plus 50% of the salary deferrals between 3% and 5% of the participant's compensation and such matching contributions are fully vested. We do not provide our employees, including the named executive officers, with any other retirement benefits, including, but not limited to, other tax-qualified retirement plans, supplemental executive retirement plans or nonqualified deferred compensation plans.

Agreements with Our Named Executive Officers

We have entered into agreements with each of our named executive officers and the details of such agreements are outlined below.

Agreement with James Lawson

On December 22, 2016, James Lawson entered into an employment agreement with Legacy AdTheorent and this agreement was subsequently amended on January 1, 2019 and January 1, 2021. The agreement had a two year term but provides for automatic one-year renewals unless either party gives notice of an intent not to renew the agreement. If Mr. Lawson's employment terminates due to his death or if we terminate his employment due to his permanent disability (as defined in the agreement), he is entitled to receive a prorated bonus for the calendar year in which the termination occurs and if he was employed as of the last day of a prior calendar year and the termination occurs prior to the date of the payment of the bonus for the prior year, he is entitled to receive the bonus that would have been payable had he remained employed through the payment date (collectively, the "Post- Termination Bonus"). If we terminate Mr. Lawson's employment without cause (as defined in the employment agreement) or if Mr. Lawson resigns for good reason (as defined in the employment agreement), he is entitled to receive (i) twelve months of base salary, (ii) the Post- Termination Bonus and (iii) continued group medical, dental and vision insurance for twelve months (provided that he pays the employee portion of such premiums), subject to his timely

------

execution and non-revocation of a general release of claims against us. The employment agreement also provides that for twelve months following his termination of employment, Mr. Lawson will not compete with us or our subsidiaries or affiliates, solicit officers from our employees or consultants, subsidiaries or affiliates, hire any person who was previously an AdTheorent officer or its subsidiaries or affiliates during the 180 days prior to such hire or solicit customers of us or its subsidiaries or affiliates.

Agreement with Bill Todd

On December 20, 2018, Bill Todd entered into an offer letter agreement with Legacy AdTheorent to serve as Chief Revenue Officer. Mr. Todd's agreement does not have a fixed term, provides for at-will employment and does not include a severance provision.

Agreements with Chuck Jordan

On May 1, 2017, Chuck Jordan entered into an offer letter agreement with Legacy AdTheorent to serve as SVP, Finance. Mr. Jordan's agreement does not have a fixed term, provides for at-will employment and does not include a severance provision.

In addition, in conjunction with Mr. Jordan's resignation from the Company effective January 30, 2023, the Company extended the period during which certain grants and bonus compensation may be paid to Mr. Jordan.

Mr. Jordan previously received three nonqualified grants under the AdTheorent Holding Company LLC Participant Interest Agreement, dated as of October 1, 2017, February 15, 2018, and May 6, 2019, respectively (collectively, the "Grants"). The Participant Interest Agreements require that any Grant exercise and corresponding payment take place on or before the date on which Mr. Jordan resigns from employment with the Company. As a separation benefit, the Company extended the period during which Mr. Jordan may exercise each of the Grants until January 31, 2024.

Mr. Jordan is a signatory to a Company-issued 2022 Executive Performance Bonus Policy related to 2022 Company performance, the terms of which require Mr. Jordan to be employed on the date of bonus payment. As a separation benefit, the Company agreed to waive this "employed upon payment" condition for Mr. Jordan to the extent any bonus is otherwise owed and payable to Mr. Jordan in due course.

Potential Post-Employment Payments

Except as discussed in "Agreement with our Named Executive Officers" above, we do not currently have any agreements, plans or arrangements which provide any NEO with payments upon termination, resignation, retirement or a Change in Control.

Board Member Compensation

During the year ended December 31, 2021, no member of Legacy AdTheorent, MCAP or AdTheorent's operating board received cash, equity or other compensation for service on the operating board or any committee thereof. Our policy is to reimburse board members for reasonable and necessary out-of-pocket expenses incurred in connection with attending board and committee meetings or performing other services in their capacities as board members. As of December 31, 2021, non-employee members of Legacy AdTheorent, MCAP or AdTheorent's operating board did not hold any outstanding options or other compensatory equity awards.

As of December 31, 2022, options to purchase 6,915,715 shares of our Common Stock granted pursuant to the 2017 Plan remained outstanding with a weighted-average exercise price of $0.61 per share and 310,891 restricted stock units with respect to our Common Stock were outstanding.

As of March 27, 2023, 330,042 underlying common shares, adjusted by the Exchange Ratio, were available for grant under the 2017 Plan.

Awards. The 2017 Plan provided for the grant of options and restricted interest units to AdTheorent's managers, executive officers, other key employees or consultants of AdTheorent and its subsidiaries.

Authorized Shares. After the 2021 Long-Term Plan became effective, no additional awards were made pursuant to the 2017 Plan.

Plan Administration. Our board, or a duly authorized committee thereof administers the 2017 Plan. Subject to the provisions of the 2017 Plan, the administrator has the power to administer the 2017 Plan and make all determinations deemed necessary or advisable for administering the 2017 Plan, including, but not limited to, the power to determine the limitations, restrictions and conditions on awards previously granted under the 2017 Plan, and construe and interpret the terms of the 2017 Plan and awards granted thereunder.

Options. Options granted under the 2017 Plan will vest at the rate specified in the award agreement as determined by the administrator. The administrator determined the term of options granted under the 2017 Plan, up to a maximum of 10 years. Payment of the exercise price for the purchase of shares of our Common Stock issued upon the exercise of an option will be made in cash (including check), or, in the discretion of the administrator, by delivery of a promissory note or other property or by cashless exercise.

Restricted Interest Units. Restricted interest units are bookkeeping entries representing an amount equal to the fair market value of one share of our Common Stock. No cash consideration is required from the recipient upon the grant of a restricted interest unit. The administrator established the terms and conditions of the restricted interest unit

------

award, including the vesting and settlement terms and unless otherwise specified in an award agreement, an unvested restricted interest unit will be forfeited upon the participant's termination of employment. A vested restricted interest unit may be settled by cash, delivery of shares of our Common Stock, or a combination thereof.

Non-Transferability of Awards. Unless otherwise provide by the administrator in an award agreement and the operating agreement, awards granted under the 2017 Plan will not be transferable except by will or the laws of descent or distribution.

Changes to Capital Structure. In the event of a reorganization, recapitalization, unit dividend or units split, or combination or other change in our Common Stock, the administrator will make appropriate adjustments to (i) the number and type of shares subject to outstanding awards and (ii) the exercise price per share of each outstanding option.

Corporate Transaction. In the event of a corporate transaction (as defined in the 2017 Plan), the administrator may provide, in its discretion, that outstanding awards granted under the 2017 Plan will become vested and if applicable, exercisable by participants who are still employed or engaged by us or one of our subsidiaries and that such awards will terminate if not exercised or settled as of the date of the corporate transaction or other prescribed time. The administrator may also provide for the assumption or substitution of outstanding awards by the acquiring entity (or parent thereof) or provide for "rollover" treatment in connection with the corporate transaction, provided that such assumption, substitution or rollover is permissible under Sections 409A or 424 of the Code, to the extent applicable.

Plan Amendment or Termination. The administrator has the authority to suspend, or terminate the 2017 Plan at any time, and the administrator may also amend the 2017 Plan at any time, provided that member approval of an amendment is required to the extent required by law, agreement or any exchange upon which our Common Stock is listed.

**2021 Long-Term Incentive Plan**

Purpose. The 2021 Long-Term Incentive Plan (the "2021 Long-Term Plan") became effective upon the date of the closing of the Business Combination and its purpose is to attract and retain the best available personnel to ensure our success and accomplish our goals, to incentivize our employees, directors, and consultants with long- term equity-based compensation to align their interests with the interests of our stockholders and to promote the success of our business.

Awards. The 2021 Long-Term Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Code ("ISOs"), to our employees and employees of our parent and subsidiary corporations, and for the grant of options which do not qualify as ISOs ("NSOs"), share appreciation rights, restricted or unrestricted share awards, restricted share unit awards ("RSUs"), deferred share units ("DSUs"), and dividend equivalent rights to our employees, directors and consultants and any of our affiliates' employees, directors and consultants. As of December 31, 2022, no options or other rights to purchase shares of our Common Stock had been granted pursuant to the 2021 Long-Term Plan.

Authorized Shares. Upon effectiveness, the maximum number of shares of our Common Stock that may be issued under our 2021 Long-Term Plan was 10,131,638 shares of our Common Stock. The number of shares of our Common Stock that will be reserved for issuance under the 2021 Long-Term Plan will automatically increase on January 1 of each year for a period of up to ten years, beginning on January 1, 2022 and continuing through January 1, 2031, by the lesser of (i) 5% of the total number of shares of our Common Stock outstanding on December 31 of the immediately preceding year, or (ii) such smaller number of shares of our Common Stock as is determined by our Board. However, before the date of any such increase, our Board may determine that that there will be no annual increase or that such increase will be less than the amount set forth in the preceding sentence. As such, on January 1, 2023, 4,348,415 shares were added to the total shares available for issuance under the 2021 Long-Term Plan. The maximum number of shares of our Common Stock that may be issued on the exercise of ISOs under our 2021 Long-Term Plan is 10,131,638 shares, subject to adjustment as provided in the 2021 Long-Term Plan. Shares issuable pursuant to the 2021 Long- Term Plan may be authorized, but unissued, or reacquired shares of our Common Stock. As of March 27, 2023, 12,078,400 shares remained available for issuance.

------

Plan Administration. Our Board, or a duly authorized committee of our Board, administers our 2021 Long-Term Plan. Our Board may delegate to one or more of our officers the authority to grant awards (to eligible persons other than themselves) based on forms approved by the administrator. Subject to the provisions of our 2021 Long-Term Plan, the administrator has the power to administer our 2021 Long-Term Plan and make all determinations deemed necessary or advisable for administering the 2021 Long-Term Plan, including, but not limited to, the power to construe and interpret the terms of our 2021 Long-Term Plan and awards granted thereunder. The 2021 Long-Term Plan provides that the administrator may not reprice underwater options, other than an adjustment to reflect certain changes to our capital structure as described below, or exchange such options for cash or another award, without stockholder approval.

Options. The administrator determines the exercise price for ISOs and NSOs, subject to the terms and conditions of our 2021 Long-Term Plan, except that the exercise price of an option will generally not be less than 100% of the fair market value of our Common Stock on the date of grant. Options granted under our 2021 Long-Term Plan will vest at the rate specified in the award agreement as determined by the administrator.

The administrator determines the term of options granted under our 2021 Long-Term Plan, up to a maximum of 10 years. Unless the terms of an optionholder's award agreement, or other written agreement between us and the recipient, provide otherwise, if an optionholder's service relationship with us or any of our affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. If an optionholder's service relationship with us or any of our affiliates ceases due to disability or death, the optionholder or a beneficiary may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of Common Stock issued upon the exercise of an option is determined by the administrator and may include (i) cash or check; (ii) the tender of shares of our Common Stock previously owned by the optionholder; (iii) a net exercise of the option; (iv) a broker-assisted cashless exercise; (v) any combination of the foregoing methods; or (vi) any other form of legal consideration approved by the administrator.

Tax Limitations on ISOs. The aggregate fair market value, determined at the time of grant, of our Common Stock with respect to ISOs that are exercisable for the first time by an employee during any calendar year under all of our stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our parent or subsidiary corporations (a "10% stockholder") unless (i) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant; and (ii) the term of the ISO does not exceed five years from the date of grant.

Share Appreciation Rights. Share appreciation rights permit the participant to receive the appreciation in the fair market value of our Common Stock between the date of grant and the exercise date. The administrator determines the purchase price or strike price for a share appreciation right, which will not be less than 100% of the fair market value of our Common Stock on the date of grant. A share appreciation right granted under our 2021 Long-Term Plan will vest at the rate specified in the share appreciation right agreement as will be determined by the administrator. Upon exercise, the participant will be entitled to receive shares of our Common Stock or cash (or any combination thereof) in an amount equal to the product of (i) the number of shares for which the share appreciation right is being exercised, multiplied by (ii) the excess of the fair market value of our Common Stock on the date of exercise over the exercise price per share.

The administrator determines the term of share appreciation rights granted under our 2021 Long-Term Plan, up to a maximum of 10 years. If a participant's service relationship with us or any of our affiliates ceases for any reason other than cause, disability, or death, the participant may generally exercise any vested share appreciation right for a period of three months following the cessation of service. If a participant's service relationship with us, or any of our affiliates, ceases due to disability or death, the participant or a beneficiary may generally exercise any vested share

------

appreciation right for a period of 12 months. In the event of a termination for cause, share appreciation rights generally terminate upon the termination date. In no event may a share appreciation right be exercised beyond the expiration of its term.

RSUs. RSUs are bookkeeping entries representing an amount equal to the fair market value of one share of our Common Stock and may be granted with or without the requirement for payment of cash or other consideration. The administrator may set vesting criteria based upon the achievement of divisional or company- wide, or individual goals (including, but not limited to, continued employment or service), or any other basis determined by the administrator in its discretion. An RSU may be settled by cash, delivery of shares, or a combination thereof. Except as otherwise provided in the applicable award agreement, or other written agreement between us and the recipient, RSUs that have not vested will be forfeited once the participant's continuous service ends for any reason.

Restricted Share Awards. Restricted share awards are grants of shares of our Common Stock that vest in accordance with the terms and conditions established by the administrator. Our 2021 Long-Term Plan also permits the administrator to award shares which are fully vested to eligible service providers. Such share awards may be granted with or without the requirement for payment of cash or other consideration. The administrator determines the terms and conditions of restricted share awards, including vesting and forfeiture terms. Participants holding restricted shares generally will have voting rights with respect to such shares upon grant without regard to vesting. If a participant's service relationship with us ends for any reason, we may receive any or all of the shares of Common Stock held by the participant that have not vested as of the date the participant terminates service with us through a forfeiture condition or a repurchase right.

DSUs. The administrator may grant DSUs to eligible persons and may also permit members of our Board or highly compensated employees to elect to forego the receipt of cash or other compensation (including shares deliverable upon the vesting of RSUs) to have us credit DSUs (to an internal 2021 Long-Term Plan account) with a fair market value of the shares or other compensation which is deferred, and may also grant DSUs to eligible service providers which are not related to a deferral of compensation. Unless otherwise provided in an award agreement, DSUs will be fully vested and will be paid to the participant (in the form of one share of our Common Stock for each DSU) in five substantially equal annual installments at the end of each of the five calendar years after the date that the participant terminates service with us and our affiliates. However, if permitted by the administrator, the DSU will be settled at such time or times elected by a participant in his or her DSU election form.

Dividend Equivalents. The administrator may grant dividend equivalent awards to participants who have awards pursuant to the 2021 Long-Term Plan (other than options and share appreciation rights) which give the holders thereof the right to receive payments equivalent to cash dividends declared during the term of the dividend equivalent right with respect to the number of shares subject to such award and will be subject to such terms and conditions as determined by the administrator.

Non-Transferability of Awards. Unless the administrator provides otherwise, awards granted under the 2021 Long-Term Plan are not transferable except by will or the laws of descent and distribution. To the extent that the administrator provides in the award agreement, an NSO, a share appreciation right (which is settled in shares) or restricted shares may be transferred to an immediate family member, a trust or other entity in which the award will be passed to the participant's beneficiaries or by gift to a charitable institution. In addition, to the extent permitted in the award agreement, an option (both ISOs and NSOs), a share appreciation right (which is settled in shares) or restricted shares may transferred pursuant to a domestic relations order.

Changes to Capital Structure. In the event there is a specified type of change in our capital structure, such as a stock split, reverse stock split, stock dividend, combination, recapitalization or reclassification of shares of our Common Stock, merger, consolidation, change in organization form, or any other increase or decrease in the number of issued shares of our Common Stock effected without receipt or payment of consideration by us, appropriate adjustments will be made to: (i) the class and maximum number of shares reserved for issuance under our 2021 Long-Term Plan; (ii) the class and maximum number of shares by which the share reserve may increase automatically each year; (iii) the class and maximum number of shares that may be issued on the exercise of ISOs; and (iv) the class and number of shares and exercise price, if applicable, of all outstanding awards granted under our 2021 Long-Term Plan.

------

Change in Control. In the event of a change in control (as defined in our 2021 Long-Term Plan), subject to the terms of a participant's award agreement or other employment-related agreement with us or one of our affiliates, any awards outstanding under our 2021 Long-Term Plan may be assumed or substituted for by any surviving or acquiring entity (or its parent or subsidiary). Instead of having outstanding awards assumed or substituted for, the administrator may, without obtaining the consent of any participant, take one or more of the following actions with respect to the outstanding awards (i) accelerate the vesting of some or all of the shares subject to the awards, (ii) provide for the payment of cash or other consideration to participants in exchange for the cancellation of the outstanding awards (based on the fair market value, on the date of the change in control, of the award being cancelled), (iii) terminate all or some of the awards upon the consummation of the change in control without payment of any consideration, or (iv) make such other modifications, adjustments or amendments to the outstanding awards or the 2021 Long-Term Plan as the administrator deems necessary or appropriate.

Plan Amendment or Termination. Our Board has the authority to amend or terminate our 2021 Long-Term Plan at any time, provided that such action does not materially impair the existing rights of any participant without such participant's written consent. We will also obtain the approval of our stockholders for amendments, including an amendment to increase the total number of shares issuable under our 2021 Long-Term Plan, to the extent required by applicable law and listing requirements. No ISOs may be granted after the tenth anniversary of the date that our Board adopts our 2021 Long-Term Plan. No awards may be granted under our 2021 Long-Term Plan while it is suspended or after it is terminated.

Recoupment. Unless otherwise provided in an award agreement, awards granted under the 2021 Long-Term Plan are subject to recoupment (or the administrator may require the termination or rescission of, or the recapture of proceeds related to, any award) if (i) the grant, vesting or payment of an award was based on an achievement of a financial result that was subsequently the subject of a material financial restatement, (ii) the participant either benefitted from a calculation that later proves to be materially inaccurate or engaged in fraud or misconduct that partially caused the need for a material financial restatement, (iii) a lower granting, vesting or payment of an award would have occurred based on the foregoing items (i) or (ii), or (iv) as required by applicable law or listing requirements. In general, this means that the administrator may, to the extent permitted by applicable law, require reimbursement or forfeiture to us of the value of the awards granted under the 2021 Long-Term Plan (whether cash-based or equity-based) to such participant received, to the extent that such value exceeds what the participant would have received based on an applicable restated performance measure or target. We will recoup such compensation to the extent required under the applicable rules, regulations and listing standards. In addition, awards granted pursuant to the 2021 Long-Term Plan and shares issued pursuant to such awards are subject to termination, rescission or recapture in the event that the participant materially violated an agreement with us or one of our affiliates, solicited any non-administrative employee to terminate his or her employment with us or one of our affiliates during the participant's service with us or within six months after termination of the participant's service with us, or the participant engaged in activities which were competitive or materially prejudicial to us during his or her service with us.

**Employee Stock Purchase Plan**

Purpose. The Employee Stock Purchase Plan ("2021 ESPP") became effective immediately prior to and contingent upon the closing of the Business Combination and its purpose is to secure the services of new employees, to retain the services of existing employees, and to provide incentives for such individuals to exert maximum efforts toward our success and that of our affiliates. The 2021 ESPP includes two components. One component is designed to allow eligible U.S. employees to purchase our Common Stock in a manner that may qualify for favorable tax treatment under Section 423 of the Code (the "423 Component") and accordingly, it will be construed in a manner that is consistent with the requirements of Section 423 of the Code. The other component will permit the grant of purchase rights that do not qualify for such favorable tax treatment (the "Non-423 Component") in order to allow deviations necessary to permit participation by eligible employees who are foreign nationals or employed outside of the U.S. while complying with applicable foreign laws and except as otherwise provided in the 2021 ESPP or determined by our Board, it will operate and be administered in the same manner as the 423 Component.

Share Reserve. The 2021 ESPP authorizes the issuance of 2,026,328 shares of our Common Stock under purchase rights granted to our employees or to employees of any of our designated affiliates. The number of shares of our Common Stock that will be reserved for issuance will automatically increase on January 1 of each year for a

------

period of ten years beginning on January 1, 2022 and ending on (and including) January 1, 2031, by the lesser of (i) 1% of the total number of shares of our Common Stock outstanding on December 31 of the immediately preceding year, (ii) 1,017,309 shares of our Common Stock, or (iii) such smaller number of shares of our Common Stock as is determined by our Board. However, before the date of any such increase, our Board may determine that that there will be no annual increase or that such increase will be less than the amount set forth in the preceding sentence. Pursuant to the ESPP, on January 1, 2023, the Company added 869,863 shares available for issuance. As of March 27, 2023, the Company had 2,784,758 shares available for issuance.

Administration. Our Board administers the 2021 ESPP and may delegate its authority to administer the 2021 ESPP to a committee of one or more members of our Board.

Offerings. The 2021 ESPP is implemented through a series of offerings under which eligible employees are granted purchase rights to purchase shares of our Common Stock on specified dates during such offerings. Under the 2021 ESPP, our Board is permitted to specify offerings with durations of not more than 27 months consisting of one or more purchase periods within each offering. Each offering will have one or more purchase dates on which shares of our Common Stock will be purchased for employees participating in the offering.

Eligibility. Generally, purchase rights may only be granted to employees, including executive officers, employed by us (or by any of our affiliates designated by our Board) on the first day of an offering if such employee has been employed by us or by one of our designated affiliates for such continuous period preceding such date (not to exceed two years) as our Board may require. Our Board may (unless prohibited by applicable law) require that employees have to satisfy one or both of the following service requirements with respect to the 423 Component: (i) being customarily employed for more than 20 hours per week; or (ii) being customarily employed for more than five months per calendar year. No employee will be eligible for the grant of any purchase rights under the 2021 ESPP if immediately after such rights are granted, such employee owns stock possessing five percent or more of the total combined voting power or value of all classes of our outstanding capital stock (or the stock of any parent or subsidiary corporation) determined in accordance with the rules of Section 424(d) of the Code. As specified by Section 423(b)(8) of the Code, no employee will be permitted to purchase shares under the 2021 ESPP at a rate in excess of $25,000 worth of our Common Stock (based on the fair market value per share of our Common Stock on the date that the purchase right is granted) for each calendar year such purchase right is outstanding.

Purchase Rights; Purchase Price. On the first day of each offering, each eligible employee is granted a purchase right to purchase up to that number of shares purchasable either with a percentage or with a maximum dollar amount, as designated by our Board, which will not exceed 15% of his or her cash compensation, including, without limitation, regular and recurring straight time gross earnings, payments for overtime and shift premium, as well as cash payments for incentive compensation, bonuses and other similar compensation (unless otherwise specified by the administrator on a uniform and nondiscriminatory basis prior to the commencement of a specified offering). Each eligible employee may purchase of up to 4,500 shares of our Common Stock on each purchase date in an offering (or such lesser number of shares determined by our Board prior to the start of the offering). Our Board may also specify (i) a maximum number of shares that may be purchased by any participant on any purchase date during an offering, (ii) a maximum aggregate number of shares that may be purchased by all participants in an offering and/or (iii) a maximum aggregate number of shares that may be purchased by all participants on any purchase date under an offering. If the aggregate number of shares issuable upon exercise of purchase rights would exceed any such maximum aggregate number, then, in the absence of any action by our Board otherwise, a pro rata allocation of the shares available, based on each participant's accumulated contributions, will be made in as nearly a uniform manner as will be practicable and equitable.

The purchase price of shares acquired pursuant to purchase rights is not less than the lesser of (i) 85% of the fair market value of a share of our Common Stock on the first day of an offering; or (ii) 85% of the fair market value of a share of our Common Stock on the date of purchase.

Participation; Withdrawal; Termination. An eligible employee may elect to participate in an offering and authorize payroll deductions as the means of making contributions by completing and delivering to us or our designee, within the time specified in the offering, an enrollment form provided by us or our designee. If permitted in the offering, a participant may thereafter reduce (including to zero) or increase his or her contributions.

------

A participant may cease making contributions and withdraw from the offering by delivering to us or our designee a withdrawal form provided us prior to any deadline before a purchase date that we may impose. Upon such withdrawal, such participant's purchase right in that offering will immediately terminate and we will distribute as soon as practicable to such participant all of his or her accumulated but unused contributions.

Purchase rights will terminate immediately if the participant either (i) is no longer an employee for any reason or for no reason (subject to any post-employment participation period required by applicable law) or (ii) is otherwise no longer eligible to participate. We will distribute the individual's accumulated but unused contributions as soon as practicable to such individual.

Purchase of Shares. On each purchase date, each participant's accumulated contributions are applied to the purchase of shares, up to the maximum number of shares permitted by the 2021 ESPP and the applicable offering, at the purchase price specified in the offering. Unless otherwise provided in the offering, if any amount of accumulated contributions remains in a participant's account after the purchase of shares on the final purchase date of an offering, then such remaining amount will not roll over to the next offering and will instead be distributed in full to such participant after the final purchase date of such offering without interest (unless otherwise required by applicable law).

Changes to Capital Structure. The 2021 ESPP provides that in the event of a change in our capital structure through actions such as a stock split, merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, liquidating dividend, combination of shares, exchange of shares, change in corporate structure, or similar transaction, our Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of shares subject to the 2021 ESPP; (ii) the class(es) and maximum number of shares by which the share reserve may increase automatically each year; (iii) the class(es) and number of shares subject to, and purchase price applicable to, outstanding offerings and purchase rights; and (iv) the class(es) and number of shares that are subject to purchase limits under each ongoing offering.

Corporate Transactions. The 2021 ESPP provides that in the event of a corporate transaction (as defined in our 2021 ESPP), any then-outstanding rights to purchase our Common Stock under the 2021 ESPP may be assumed, continued, or substituted for by any surviving or acquiring corporation (or its parent company). If the surviving or acquiring corporation (or its parent company) elects not to assume, continue, or substitute for such purchase rights, then (i) the participants' accumulated payroll contributions will be used to purchase shares of our Common Stock within 10 business days before such corporate transaction, and such purchase rights will terminate immediately after such purchase, or (ii) our Board, in its discretion, may terminate outstanding offerings and purchase rights and refund the participants' accumulated contributions.

Transferability. During a participant's lifetime, purchase rights are exercisable only by a participant. Purchase rights are not transferable by a participant, except by will, by the laws of descent and distribution, or, if permitted by us, by a beneficiary designation.

Amendment, Suspension or Termination. Our Board has the authority to amend, suspend or terminate the 2021 ESPP, except in certain circumstances such amendment, suspension or termination may not materially impair any outstanding purchase rights without the holder's consent. Stockholder approval is required for any amendment to the 2021 ESPP if such approval is required by applicable law or listing requirements

**Anti-Hedging Policy**

Pursuant to our Insider Trading Policy, our directors and executives are prevented from engaging in hedging or monetization transactions (including but not limited to zero-cost collars, prepaid variable forwards, equity swaps, puts, calls, collars, forwards and other derivative instruments), as such transactions allow individuals to continue to own our securities without the full risks and rewards of ownership and as a result, not have the same objectives as other stockholders.

**Securities Authorized for Issuance under Equity Compensation Plans**

As of December 31, 2022, there were 7,677,848 shares of Common Stock available for issuance under the 2021 Plan and 2,026,328 shares of Common Stock available for issuance under the 2021 ESPP, each of which our

stockholders approved on December 21, 2021 in connection with the Business Combination and became effective immediately upon the Closing.

We also describe below certain other transactions with our directors, executive officers and stockholders.

**Stockholders' Agreement**

**Amended and Restated Registration Rights Agreement**

In connection with the Closing of the Business Combination, on the Closing Date we entered into an amended and restated registration rights agreement (the "Registration Rights Agreement") with certain MCAP stockholders (including the Sponsor) and certain Legacy AdTheorent members (such stockholders, the "Holders"), pursuant to which, among other things, the Holders are entitled to certain registration rights in respect of the registrable securities under the Registration Rights Agreement. The Registration Rights Agreement also provides the Holders with "piggy-back" registration rights, subject to certain requirements and customary conditions.

**Member Support Agreement**

In connection with the execution of the Business Combination Agreement, MCAP, Legacy AdTheorent and certain Legacy AdTheorent members, who held a majority of Legacy AdTheorent's membership interests, entered into a Member Support Agreement, pursuant to which, among other things, the Legacy AdTheorent members agreed to vote in favor of the Business Combination Agreement, the Business Combination, and the other transactions contemplated by the Business Combination Agreement ("Transactions") at a meeting of Legacy AdTheorent members called to approve the Business Combination Agreement, the Business Combination, and Transactions (or to act by written consent approving the Business Combination Agreement, the Business Combination, and Transactions).

------

**Indemnity Agreements**

In connection with the Closing of the Business Combination, we entered into indemnity agreements (each, an "Indemnity Agreement") with each of our directors and executive officers. These Indemnity Agreements provide the directors and executive officers with contractual rights to indemnification and advancement for certain expenses, including attorneys' fees, judgments, fines and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers.

**MCAP Related Person Transactions**

**Founder Shares**

In December 2020, MCAP issued an aggregate of 7,187,500 Founder Shares to the Sponsor, which is controlled by Theodore L. Koenig, for an aggregate purchase price of $25,000 in cash, or approximately $0.003 per share. On February 25, 2021, MCAP effected a stock dividend, resulting in an aggregate 7,906,250 Founder Shares. The Founder Shares, after giving effect to the stock dividend, included an aggregate of up to 1,031,250 shares of MCAP common stock subject to forfeiture if the over-allotment option with respect to MCAP's initial public offering was not exercised by the underwriters in full. In connection with the underwriters' full exercise of their over-allotment option in March 2021, the 1,031,250 MCAP shares were no longer subject to forfeiture. Such MCAP shares had an aggregate market value of approximately $78.6 million based on the last sale price of $9.94 per share on Nasdaq on December 1, 2021.

In connection with the Business Combination, the Sponsor agreed not to transfer, assign or sell its Founder Shares until the earlier of (i) one year after the date of the consummation of the initial business combination or (ii) the date on which the closing price of our Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30- trading day period commencing after the initial business combination, or earlier, in either case, if, subsequent to the initial business combination, the date the Company consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of our stockholders having the right to exchange their shares of Common Stock for cash, securities or other property.

**Private Warrants**

The Sponsor purchased an aggregate of 5,983,333 Private Warrants, each exercisable for one share of MCAP common stock at $11.50 per share, for a purchase price of $8,975,000, or $1.50 per warrant. Such warrants had an aggregate market value of approximately $6.9 million based on the last sale price of $1.16 per warrant on Nasdaq on December 1, 2021. MCAP's charter required MCAP to complete an initial business combination prior to March 2, 2023 (unless MCAP submits and its stockholders approve an extension of such date). Per the terms of the Business Combination Agreement, the Sponsor forfeited 551,096 Private Placement Warrants.

In December 2020, MCAP issued an unsecured promissory note to the Sponsor, pursuant to which MCAP could borrow up to an aggregate principal amount of $300,000 to be used for a portion of the expenses of MCAP's initial public offering. This loan was non-interest bearing, unsecured and due at the earlier of June 30, 2021 or the closing of MCAP's initial public offering. The loan would be repaid upon the closing of MCAP's initial public offering out of the offering proceeds not held in the trust account. On March 2, 2021, the $250,000 outstanding under the promissory note was repaid.

**Subscription Agreements**

Concurrently with the execution of the Business Combination Agreement, MCAP entered into subscription agreements with certain investors (the "PIPE Investors"), pursuant to which the PIPE Investors agreed to subscribe for and purchase, and MCAP agreed to issue and sell to the PIPE Investors, immediately prior to the Closing, an aggregate of 12,150,000 shares of common stock for a purchase price of $10.00 per share, for aggregate gross proceeds of $121.50 million. The shares issued to the PIPE Investors were issued pursuant to and in accordance with the exemption from registration under the Securities Act of 1933 (the "Securities Act") under Section 4(a)(2) and/or Regulation D promulgated thereunder.

------

**Additional Related Party Transactions**

Other than as described above, no compensation of any kind has been paid by MCAP, Legacy AdTheorent or the Company to the Sponsor, executive officers and directors, or any of their respective affiliates, for services rendered prior to or in connection with the completion of the Business Combination. However, these individuals have been or will be reimbursed for any out-of-pocket expenses incurred in connection with activities on MCAP's behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. The Audit Committee has reviewed on a quarterly basis all payments that were made to the Sponsor, officers, directors or its or their affiliates.

All ongoing and future transactions between the Company and any of its officers and directors or their respective affiliates will be on terms believed by the Company to be no less favorable to it than are available from unaffiliated third parties. Such transactions will require prior approval by a majority of our uninterested "independent" directors or the members of our board who do not have an interest in the transaction, in either case who had access, at our expense, to our attorneys or independent legal counsel. We will not enter into any such transaction unless our disinterested "independent" directors determine that the terms of such transaction are no less favorable to the Company than those that would be available to the Company with respect to such a transaction from unaffiliated third parties.

Monroe Capital LLC

In addition, the Sponsor, its manager, certain of its members, and certain of MCAP's officers and directors are affiliated with Monroe Capital LLC. Affiliates of Monroe Capital LLC had issued debt to AdTheorent with outstanding principal amount of approximately $24.4 million as of September 30, 2021, which debt was fully repaid by us in December 2021 as a condition to the closing of the Business Combination. Affiliates of Monroe Capital LLC also owned 1,250,000 shares in AdTheorent, representing 2.55% of the fully diluted equity ownership, prior to the closing of the Business Combination.

Certain Legacy AdTheorent members that received shares of our Common Stock in the Business Combination have entered into a Lock-Up Agreement with Company, pursuant to which such members have agreed that, from the Closing Date until the 180th day after the Closing Date, they will not (subject to certain exceptions) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, any shares of Common Stock (including the shares of Common Stock issued or issuable upon the exercise of any other in connection with the transactions contemplated by the Business Combination Agreement).

**Related Person Transactions Policy**

Our Board has adopted a written Policy and Procedures With Respect to Related Person Transactions that sets forth the Company's policies and procedures regarding the identification, review, consideration and oversight of "related person transactions." For purposes of the Company's policy only, a "related person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company or any of its subsidiaries are participants involving an amount that exceeds $120,000, in which any "related person" has a material interest.

Transactions involving compensation for services provided to the Company as an employee, consultant or director will not be considered related person transactions under this policy. A "related person" is any executive officer, director, nominee to become a director or a holder of more than 5% of any class of the Company's voting securities, including any of their immediate family members and affiliates, including entities owned or controlled by such persons.

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of the Company's voting securities, information regarding the proposed related person transaction must be presented to the Company's Audit Committee for review.

------

The Company's Audit Committee will approve only those transactions that it determines are in the best interests of the Company and its stockholders.

**PROPOSAL TWO**

**RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

Our Audit Committee has retained BDO as our independent registered public accounting firm for the year ending December 31, 2023. A proposal will be presented at the Annual Meeting to ratify this retention. Ratification of the retention of our independent registered public accounting firm requires the affirmative vote of the majority of shares present in person or represented by proxy at the Annual Meeting and entitled to vote. If the stockholders fail to ratify such selection, another independent registered public accounting firm will be considered by our Audit Committee, but the Audit Committee may nonetheless choose to engage BDO. Even if the retention of BDO is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders. We have been advised that a representative of BDO will be present at the Annual Meeting and will be available to respond to appropriate questions and, if such person chooses to do so, make a statement.

**THE BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" RATIFICATION OF THE RETENTION OF BDO AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2023.**

**CHANGE IN AUDITORS**

On December 22, 2021, our board of directors approved the engagement of BDO as the Company's independent registered public accounting firm to audit the Company's consolidated financial statements for the year ending December 31, 2021. BDO served as the independent registered public accounting firm of Legacy AdTheorent prior to the Business Combination. Accordingly, Marcum LLP ("Marcum"), MCAP's independent registered public accounting firm prior to the Business Combination, was informed that it would be dismissed and replaced by BDO as the Company's independent registered public accounting firm.

The audit report of Marcum on MCAP's financial statements as of December 31, 2020, and for the period from November 12, 2020 (date of inception) to December 31, 2020, did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainties, audit scope, or accounting principles except for an explanatory paragraph in such report regarding substantial doubt about the Company's ability to continue as a going concern.

During the period from November 12, 2020 (inception) through December 31, 2020, and the subsequent period through September 30, 2021, there were no disagreements with Marcum on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Marcum, would have caused it to make a reference in connection with their opinion to the subject matter of the disagreement or reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided Marcum with a copy of the disclosures made by us in response to Item 304(a) of Regulation S-K under the Exchange Act ("Regulation S-K") and has requested that Marcum furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made by the registrant in response to Item 304(a) of Regulation S-K and, if not, stating the respects in which it does not agree.

**Principal Accountant Fees and Services**

BDO billed the Company for services for our fiscal year ended December 31, 2022 and 2021, as set forth in the table below. The fees listed are aggregate fees for services performed for the year—regardless of when the fee was actually billed.

| Audit Fees | $728 | $1762 |
| Audit-Related Fees |  |  |
| Tax Fees |  |  |
| All Other Fees |  |  |
| Total | $728 | $1762 |

---

**Audit Fees**—Consists of fees for professional services necessary to perform an audit or review in accordance with the Public Company Accounting Oversight Board, including services rendered for the audit of our annual financial statements, quarterly reviews of the Company's interim financial statements, as well as services related to Forms S-1 and S-4 in 2021 and 2022.

**Audit-Related Fees**—There were no audit-related fees for 2022.

**Tax Fees**—There were no tax fees for 2022.

**All Other Fees**—There were no other fees for 2022.

**Pre-Approval Policies and Procedures**—The Audit Committee has adopted a policy that requires advance approval of all audit, audit-related, tax services and other services performed by the independent registered public accounting firm. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services.

Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent auditor is engaged to perform it. The Audit Committee has delegated to the Chair of the Audit Committee authority to approve permitted services, provided that the Chair reports any decisions to the Audit Committee at its next scheduled meeting.

**Attendance at Annual Meeting**—Representatives of BDO are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so. Because we expect representatives of BDO to be present at the Annual Meeting, representatives of BDO are expected to be available to respond to appropriate questions.

------

**AUDIT COMMITTEE REPORT**

The Audit Committee has reviewed and discussed our audited financial statements for the fiscal year ended December 31, 2022 with management.

The Audit Committee has discussed with our independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and SEC.

The Audit Committee has received the written disclosures and the letter from the independent accountant required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the Audit Committee concerning independence, and has discussed with the independent accountant the independent accountant's independence.

Based on these reviews and discussions, the Audit Committee recommended to the Board that our audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2022 for filing with the SEC.

The Audit Committee has also appointed BDO as the Company's independent registered public accounting firm for the fiscal year ended December 31, 2023.

Respectfully submitted,

THE AUDIT COMMITTEE

**PROPOSAL THREE**

**THE OFFICER EXCULPATION AMENDMENT**

**Background of the Proposal**

The State of Delaware, which is the Company's state of incorporation, recently enacted legislation that enables Delaware companies to limit the liability of certain of their officers in limited circumstances. In light of this update, we are proposing the Officer Exculpation Amendment to the Company's Charter to add a provision exculpating certain of the Company's officers from liability, as permitted by Delaware law. The new Delaware legislation only permits, and the Officer Exculpation Amendment would only permit, exculpation for direct claims (as opposed to derivative claims made by stockholders on behalf of the corporation) and would not apply to breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit.

**Reasons for the Proposal**

The Board believes that eliminating personal monetary liability for officers under certain circumstances is reasonable and appropriate.

Delaware corporations that fail to adopt officer exculpation provisions may experience a disproportionate amount of nuisance litigation and disproportionately increased costs in the form of increased director and officer liability insurance premiums, as well as diversion of management attention from the business of the corporation. Prior to the amendment of Section 102(b)(7) of the DGCL, Delaware law permitted Delaware corporations to exculpate directors from personal liability for monetary damages associated with breaches of the duty of care, but that protection did not extend to a Delaware corporation's officers. Consequently, shareholder plaintiffs have employed the tactic of bringing certain claims that would otherwise be exculpated if brought against directors against individual officers to avoid dismissal of such claims. The amendment to Section 102(b)(7) of the DGCL was adopted to address inconsistent treatment between officers and directors and the rising costs of litigation and insurance. Adopting the Officer Exculpation Amendment would facilitate the Company diverting additional resources towards its business rather than expenses related to nuisance litigation and liability insurance premiums.

Adopting the Officer Exculpation Amendment would enable our officers to exercise their business judgment in furtherance of our shareholders' interests without the potential distraction of risking personal liability. An officer's role often requires them to make decisions on crucial matters and in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits, or proceedings seeking to impose liability based on hindsight, and regardless of merit.

Further, we believe that failing to adopt the Officer Exculpation Amendment could impact our recruitment and retention of exceptional officer candidates who conclude that the potential exposure to liabilities, costs of defense, and other risks of proceedings exceeds the benefits of serving as an officer of the Company.

A Delaware corporation seeking to extend the benefits of the newly amended Section 102(b)(7) to its corporate officers must amend its certificate of incorporation, as the protections do not apply automatically and must be embedded in the corporation's certificate of incorporation to be effective. Accordingly, the Board has determined it advisable and in the best interests of the Company and its stockholders to seek stockholders' approval for the Officer Exculpation Amendment.

**Vote Required and Recommendation of the Board of Directors**

Approval by stockholders of the Officer Exculpation Amendment requires the affirmative vote of a majority of the outstanding voting stock of the Company.

Taking into account the narrow class and type of claims for which officers' liability would be exculpated, and the benefits the Nominating and Corporate Governance Committee believes would accrue to the Company and its stockholders in the form of (i) an enhanced ability to attract and retain talented officers, (ii) limiting litigation and

------

insurance liability premium costs for its officers and (iii) better ensuring the Company's officers would be able to exercise their business judgment, the Nominating and Corporate Governance Committee recommended to the Board an amendment to the Charter to provide such exculpation to the extent permitted by Delaware law. Accordingly, we ask our stockholders to approve the Officer Exculpation Amendment.

The discussion above is qualified in its entirety by reference to the full text of the proposed Officer Exculpation Amendment, which is attached hereto as Annex A. If the stockholders approve the Officer Exculpation Amendment at the Annual Meeting, the Company will file a Certificate of Amendment to the Charter with the Secretary of State of the State of Delaware.

**THE BOARD UNANIMOUSLY RECOMMENDS A VOTE "FOR" THE OFFICER EXCULPATION AMENDMENT PROPOSAL.**

------

**STOCKHOLDER PROPOSALS FOR 2024 ANNUAL MEETING OF STOCKHOLDERS**

Stockholders who intend to present proposals at the Company's annual meeting of stockholders in 2024 pursuant to Rule 14a-8 under the Exchange Act must send notice of their proposal to us so that we receive it no later than December 14, 2023.

Stockholder proposals should be addressed to AdTheorent Holding Company, Inc. 330 Hudson Street, 13th Floor New York, New York 10013, Attention: Secretary.

**OTHER MATTERS**

**Upon written request by any stockholder entitled to vote at the Annual Meeting, we will promptly furnish, without charge, a copy of the Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which we filed with the SEC, including AdTheorent's consolidated financial statements.

Requests should be addressed to AdTheorent Holding Company, Inc. 330 Hudson Street, 13th Floor New York, New York 10013, Attention: Secretary.**
