#### Voting Your Shares
Stockholders of record holding shares of common stock of the Company, par value $0.001 per share (the "Shares"), as of the close of business on March 23, 2026 (the "Record Date") are entitled to vote at the Annual Meeting.

Beneficial owners whose Shares are held at a brokerage firm or by a bank or other nominee should follow the voting instructions that they received from the nominee.

We are furnishing our proxy materials to all of our stockholders over the Internet rather than in paper form. We believe that this delivery process will lower the costs of printing and distributing our proxy materials and reduce our environmental impact, without impacting our stockholders' timely access to this important information. Accordingly, stockholders of record at the close of business on the Record Date, March 23, 2026, will receive a Notice of Internet Availability of Proxy Materials (the "Notice") and may vote at the Annual Meeting. Such stockholders will also receive notice of any postponements or adjournments of the meeting. The Notice is being distributed to stockholders on or about April 7, 2026.

 **Whether or not you plan to attend the annual meeting, please vote by Internet at your earliest convenience or complete, sign, date and return the proxy card so that your shares will be represented at the meeting. You may choose to attend the meeting virtually and cast your votes online during the meeting even if you vote by Internet or fill out and return a proxy card by mail. You may also revoke your proxy and cast your votes online during the meeting.** 

By Order of the Board of Directors,

If elected, each of these individuals will serve as a Class II director until the 2029 Annual Meeting of Stockholders and until such director's successor has been elected and qualified, or until such director's earlier death, resignation or removal. Although the Class II directors will be elected for a term of three years, our Board previously pledged to sunset certain provisions of our certificate of incorporation, including our classified board structure, on or before our annual meeting in 2028 and, if such sunset occurs, all of our directors, including our Class II directors, will be up for election at our annual meeting held in 2028. The relevant experiences, qualifications, attributes or skills of each nominee that led the Board to recommend the above persons as a nominee for director are described in "Board and Corporate Governance Practices—Board Composition."

Unless otherwise instructed, the proxyholders will vote proxies FOR the nominees of the Board. The Board has no reason to believe that any of its nominees will be unable or unwilling to serve if elected. However, if any of the Board's nominees should become unable for any reason or unwilling for good cause to serve as a director at any point before the Annual Meeting or any adjournment or postponement of the meeting, the Board may reduce the size of the Board or nominate another candidate for election as a Class II director. If the Board nominates a new candidate, unless otherwise provided, the form of proxy attached to this Proxy Statement permits the proxyholders to use their discretion to vote for that candidate.

 **THE BOARD RECOMMENDS THAT YOU VOTE FOR THE ELECTION OF EACH OF R. DAVIS NOELL, LUCY STAMELL DOBRIN AND GARY SWIDLER.**

 **PROPOSAL 2 Advisory Vote on the Compensation of our Named Executive Officers** 

<br> At the 2023 Annual Meeting of Stockholders, our stockholders indicated by a non-binding advisory vote, that they agreed with the Board's recommendation that it solicit annually the approval, on an advisory and non-binding basis, of the compensation of our named executive officers as a whole ("Say-on-Pay"). Accordingly, the Company adopted a policy that is consistent with that indication.

This non-binding advisory vote is intended to address the overall compensation of our named executive officers and our compensation philosophy and practices described in this Proxy Statement, but not any specific item of compensation. The compensation of our named executive officers subject to this proposal is disclosed in the section titled "Compensation Discussion and Analysis," the compensation tables, and the related narrative disclosure contained in this Proxy Statement. As discussed in this Proxy Statement, we believe that our compensation program aligns the attraction, motivation and retention of our executive officers with promoting the interests of our stockholders.

The Board recommends our stockholders vote, on a non-binding advisory basis, "**FOR**" the following resolution:

"RESOLVED, that the stockholders approve, in a non-binding advisory vote, the compensation paid to the Company's named executive officers, as disclosed in this Proxy Statement."

Approving the Say-on-Pay vote requires the affirmative vote of a majority of the voting power of the Shares present virtually or by proxy during the Annual Meeting and entitled to vote thereon. Abstentions are considered shares present and entitled to vote on this proposal and, thus, will have the same effect as a vote "AGAINST" each of the proposed voting frequencies. Broker non-votes will have no effect on the outcome of this proposal.

As an advisory vote, the result of this proposal is non-binding. Although the vote is non-binding, the Board and the Compensation Committee of the Board (the "Compensation Committee") value the opinions of our stockholders in this matter and, will consider the outcome of this vote when making future decisions regarding the compensation of our named executive officers.

 **THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.**

 **PROPOSAL 3 Ratification of Appointment of Independent Registered Public Accounting Firm** 

<br> The Audit Committee of the Board (the "Audit Committee") is responsible for the appointment, compensation, retention and oversight of our independent registered public accounting firm ("independent auditor") and annually evaluates the independent auditor's qualifications, performance and independence.

The Audit Committee has appointed Deloitte & Touche LLP ("Deloitte") as our independent auditor for the fiscal year ending December 31, 2026. Deloitte has served as the independent auditor for the Company since 2019. Deloitte's background knowledge of the Company, combined with its industry expertise, has enabled it to carry out its audits of our financial statements with effectiveness and efficiency. The members of the Audit Committee believe that the continued retention of Deloitte as our independent auditor is in the best interest of the Company and its stockholders. In determining whether to reappoint Deloitte, the Audit Committee considered factors such as:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Deloitte's independence and objectivity;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Deloitte's and the lead engagement partner's capability and expertise in handling the breadth and complexity of our operations;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Deloitte's tenure as independent auditor for the Company;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

historical and recent performance of Deloitte, including the extent and quality of communications with members of the Audit Committee; and

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the impact of a change in the independent auditor.

The Audit Committee is involved in the selection of Deloitte's lead engagement partner and ensures that the lead partner's engagement is limited to no more than five consecutive years of service in that role (in accordance with SEC rules).

We request that our stockholders ratify the appointment of Deloitte as our independent auditor for fiscal year 2026. If the stockholders do not ratify such appointment, the Audit Committee will take note and may reconsider its retention of Deloitte. If such appointment is ratified, the Audit Committee will still have the discretion to replace Deloitte at any time during the year. Representatives of Deloitte are expected to be present at the Annual Meeting and will have the opportunity to make a statement. They will also be available to respond to questions from stockholders regarding their audit of our consolidated financial statements for fiscal year 2025.

 **THE BOARD RECOMMENDS THAT YOU VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF DELOITTE AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2026.**

 **Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters** 

<br> The following table sets forth certain information as of March 23, 2026 with respect to the beneficial ownership of the Shares by (i) each person known to own beneficially more than five percent of the Shares; (ii) each of our directors and director nominees; (iii) each of our named executive officers; and (iv) all of our current executive officers, directors and director nominees as a group.

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a "beneficial owner" of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person's ownership percentage, but not for purposes of computing any other person's percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Percentage computations are based on 157,242,793 Shares outstanding as of March 23, 2026. Except as otherwise indicated in the footnotes to the table, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the indicated Shares. Unless otherwise set forth in the footnotes to the table, the address for each listed stockholder is 462 Broadway, New York, NY 10013.

<br> #### Compensation Discussion and Analysis
Introduction

This Compensation Discussion and Analysis provides information regarding the 2025 compensation program for our "Named Executive Officers" or "NEOs." For 2025, our Named Executive Officers were:

<br> Mark Zagorski, our Chief Executive Officer (our "CEO"); Nicola Allais, our Chief Financial Officer; Julie Eddleman, our Executive Vice President and Global Chief Commercial Officer; and Andrew Grimmig, our General Counsel and Chief Legal Officer.

#### Executive Transition
On September 15, 2025, Ms. Eddleman notified us of her decision to resign as our Executive Vice President and Global Chief Commercial Officer, and, at that time, we entered into an Executive Separation Agreement and a Consulting Agreement (the "Transition Agreement") with Ms. Eddleman to provide for an orderly transition of her duties and responsibilities. Ms. Eddleman's resignation was effective as of December 31, 2025, and Mr. Mougis was appointed as our Global Chief Commercial Officer, effective as of January 1, 2026. The material terms and conditions of the Transition Agreement are described below in the section entitled "Post-Employment Compensation."

This Compensation Discussion and Analysis describes material elements of our executive compensation program during 2025. It also provides an overview of our executive compensation philosophy, including our principal compensation policies and practices. Finally, it analyzes how and why the Compensation Committee and our Board arrived at the specific compensation decisions for our Named Executive Officers in 2025 and discusses the key factors that were considered in determining their compensation.

#### Relationship Between Pay and Performance
We design our executive compensation program to align the attraction, motivation, and retention of our executive officers with the goal of promoting the interests of our stockholders. In an effort to achieve this balance and to motivate and reward individual initiative and effort, we seek to ensure that a meaningful portion of our executive officers' annual target total direct compensation opportunity is both "at-risk" and variable in nature.

---

| | | | |
|:---|:---|:---|:---|
| We emphasize variable compensation that appropriately rewards our executive officers through the following two principal compensation elements: | We emphasize variable compensation that appropriately rewards our executive officers through the following two principal compensation elements: | We emphasize variable compensation that appropriately rewards our executive officers through the following two principal compensation elements: | We emphasize variable compensation that appropriately rewards our executive officers through the following two principal compensation elements: |
| 1.  | Our executive officers participate in our Bonus Plan, which provides the opportunity for cash bonus awards if our executive officers produce short-term results aligned with long-term stockholder value, such as revenue and Adjusted EBITDA, that meet or exceed certain business and financial objectives set by the Compensation Committee, after considering the Company's annual operating plan. For information as to how we calculate Adjusted EBITDA, which is a non-GAAP financial measure, please refer to page 53 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.  | 2.  | We grant PSU awards and RSU awards, which in the aggregate typically comprise a majority of our executive officers' annual target total direct compensation opportunities. The actual value received by our NEOs for these equity awards depends on, among other things, the value of our common stock and coupled with achieving the quantitative performance objectives and multi-year vesting periods that apply to them. These awards are intended to incentivize our executive officers to build sustainable long-term value for the benefit of our stockholders.  |

---

These variable pay elements ensure that, each year, a substantial portion of our executive officers' target total direct compensation is contingent (rather than fixed) in nature, with the amounts ultimately payable subject to variability above or below target levels commensurate with our actual performance. We believe that these compensation elements provide balanced incentives for our executive officers to meet our business objectives and drive long-term growth.

#### Executive Compensation Policies and Practices
We endeavor to maintain sound governance standards consistent with our executive compensation policies and practices. The Compensation Committee reviews our executive compensation program on an annual basis to ensure consistency with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. The following summarizes our executive compensation-related policies and practices that were in effect during 2025:

#### Stockholder Advisory Vote on Our Named Executive Officer Compensation
At our 2025 Annual Meeting of Stockholders, we held a non-binding, advisory vote on the compensation of our Named Executive Officers (commonly known as a "Say-on-Pay" vote). Our executive compensation program for 2024 was approved by approximately 98.0% of the votes cast (for, against, and abstentions). There are many factors contributing to our Board's and the Compensation Committee's evaluation of whether to make significant changes to our executive compensation program, including stockholder feedback, peer compensation group actions, target pay levels, performance metrics, an analysis of competitive market data, and other compensation policies. Following this Say-on-Pay vote, based on a variety of the aforementioned factors, including, in part, the strong level of support for our executive compensation program demonstrated by the results of the 2025 Say-on-Pay vote, our Board and the Compensation Committee determined not to implement any significant changes to our executive compensation program for 2026. Our Board and the Compensation Committee intend to regularly consider the result of the Say-on-Pay vote to determine the compensation of our executive officers, including our NEOs.

We value the opinions of our stockholders. Stockholder feedback, including through direct discussions and future Say-on-Pay votes, will be reported to our Board throughout the year. Our goal is to be responsive to our stockholders and ensure we understand and address their concerns and observations. Our Board and the Compensation Committee will consider the outcome of our Say-on-Pay vote, as well as feedback received throughout the year, when making compensation decisions for our executive officers.

At our 2023 Annual Meeting of Stockholders, we also conducted a non-binding stockholder advisory vote on the frequency of future Say-on-Pay votes (commonly known as a "Say-When-on-Pay" vote). Our stockholders expressed a preference for holding future Say-on-Pay votes on an annual, rather than a biennial or triennial, basis. In recognition of this preference, the recommendation of our Board and other factors considered, our Board has determined that, until the next Say-When-on-Pay vote, we will hold annual Say-on-Pay votes.

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| Our executive compensation program is guided by our overarching philosophy of paying for performance. We strive to provide an executive compensation program that is competitive, rewards achievement of our business objectives, and aligns our executive officers' interests with those of our stockholders. Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:  | Our executive compensation program is guided by our overarching philosophy of paying for performance.

Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:  |
| 1.  | Provide market competitive compensation and benefit levels that will attract, motivate, reward, and retain a highly talented team of executive officers within the context of responsible cost management  | 2.  | Establish a direct link between our financial and operational results and achievement of strategic objectives and the compensation of our executive officers  | 3.  | Align the interests and objectives of our executive officers with those of our stockholders by linking their long-term incentive compensation opportunities to stockholder value creation and their cash incentives to our annual performance  |

---

We structure the annual compensation of our executive officers using three principal elements: base salary, annual cash bonus opportunities, and long-term equity incentive opportunities in the form of equity awards.

We have not adopted policies or employed guidelines for allocating compensation between current and long-term compensation, between cash and non-cash compensation, or among different forms of non-cash compensation. As described below, the Compensation Committee considers a variety of factors in formulating and proposing the appropriate yearly mix among such compensatory elements, including our compensation philosophy and the value of outstanding equity awards granted in prior years.

Succession Planning and Personnel Decisions

The Compensation Committee and our Board regularly review our executive management succession plan to enable business continuity in the event a senior leader departs from the Company. The review includes a discussion of potential successors, including qualified internal candidates along with external candidates, an evaluation of their readiness for the role, and a discussion of development or other opportunities to prepare them for the role. We discuss development plans for potential successors identifying specific skills, training, or other development opportunities to help such individuals prepare for the position.

Compensation-Setting Process

#### Role of the Compensation Committee
The Compensation Committee discharges many of the responsibilities of our Board relating to the compensation of our executive officers, including our Named Executive Officers, and presents compensation recommendations to our Board for approval pursuant to its charter. The Board reviews the Compensation Committee's recommendations and approves the compensation of our executive officers, including our NEOs. Similarly, the Compensation Committee develops and presents recommendations to our Board for approval with respect to the compensation of the non-employee members of our Board. The Compensation Committee has the overall responsibility for overseeing our compensation and benefits policies generally, and overseeing and evaluating the compensation plans, policies, and practices applicable to our executive officers.

In carrying out its responsibilities, the Compensation Committee evaluates our compensation policies and practices with a focus on the degree to which these policies and practices reflect our executive compensation philosophy, develops strategies and makes recommendations that it believes further our philosophy or align with developments in best compensation practices and reviews the performance of our executive officers when making recommendations with respect to their compensation.

[**TABLE OF CONTENTS**](#TOC)

The Compensation Committee's authority, duties, and responsibilities are further described in its charter, which is reviewed annually and revised and updated as warranted. The charter of the Compensation Committee is available without charge at https://ir.doubleverify.com/corporate-governance/governance-documents.

The Compensation Committee retains a compensation consultant (as described below) to provide support in its review and assessment of our executive compensation program; however, the Compensation Committee exercises its own judgment in developing its recommendations to our Board with respect to the compensation of our executive officers, including our NEOs.

#### Setting Target Total Direct Compensation
The Compensation Committee conducts an annual review of the compensation arrangements of our executive officers, including our NEOs, typically during the first quarter of the fiscal year. As part of this review, the Compensation Committee evaluates the base salary levels, annual cash bonus opportunities, and long-term incentive compensation opportunities of our executive officers and all related performance criteria.

The Compensation Committee does not establish a specific target for formulating the compensation opportunities of our executive officers. In developing recommendations about the compensation of our executive officers, the members of the Compensation Committee rely primarily on their general experience and subjective considerations of various factors, including the following:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Our executive compensation program objectives;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Our performance against the financial, operational, and strategic objectives established by the Compensation Committee and our Board;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Each individual executive officer's knowledge, skills, experience, qualifications, and tenure relative to other similarly situated executives at the companies in our compensation peer group and, in certain instances, selected broad-based compensation surveys;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The scope of each executive officer's role and responsibilities compared to other similarly situated executives at the companies in our compensation peer group and, in certain instances, selected broad-based compensation surveys;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The prior performance of each individual executive officer, based on a subjective assessment of such executive officer's contributions to our overall performance, ability to lead the executive officer's business unit or function, and work as part of a team, all of which reflect our core values;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The potential of each individual executive officer to contribute to our long-term financial, operational, and strategic objectives;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The retention risk (and related replacement cost) of each individual executive officer;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Our CEO's compensation relative to that of our executive officers, and compensation parity among our executive officers;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Our financial performance relative to our peers;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The compensation practices of our compensation peer group and the companies in selected broad-based compensation surveys and the positioning of each executive officer's compensation in a ranking of peer company compensation levels based on an analysis of competitive market data; and

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The recommendations of our CEO with respect to the compensation of our executive officers (except with respect to his own compensation).

These factors provide the framework for formulating and developing recommendations regarding the compensation opportunity for each executive officer, including each NEO. No single factor is determinative in developing these recommendations, nor is the impact of any individual factor on the determination of pay levels quantifiable.

The Compensation Committee does not assign any predetermined weight to these factors, nor does it apply any formulas in developing its compensation recommendations for our executive officers. The

18 Executive and Director Compensation 2026 PROXY STATEMENT

[**TABLE OF CONTENTS**](#TOC)

members of the Compensation Committee consider this information in light of their individual experience, knowledge of the Company, knowledge of the competitive market, knowledge of each executive officer, and business judgment in formulating and making their recommendations.

The Compensation Committee does not engage in formal benchmarking against other companies' compensation programs or practices to establish our compensation levels or make specific compensation recommendations with respect to our executive officers. Instead, in formulating and developing its recommendations, the Compensation Committee reviews information summarizing the compensation paid at a representative group of peer companies, to the extent that the executive positions at these companies are considered comparable to our positions and informative of the competitive environment and more broad-based compensation surveys to gain a general understanding of market compensation levels.

The Compensation Committee takes accounting considerations into account in designing compensation plans and arrangements for our executive officers and other employees. Chief among these is Financial Accounting Standards Board Accounting Standards Codification Topic 718 ("ASC Topic 718"), the standard which governs the accounting treatment of certain stock-based compensation. Among other things, ASC Topic 718 requires us to record a compensation expense in our income statement for all equity awards granted to our executive officers and other employees. This compensation expense is based on the grant date "fair value" of the equity award and, in most cases, will be recognized ratably over the award's requisite service period (which, generally, will correspond to the award's vesting schedule). This compensation expense is also reported in the compensation tables below, even though recipients may never realize any value from their equity awards.

#### Role of Management
In discharging its responsibilities, the Compensation Committee works with members of our management, including our CEO. Our management assists the Compensation Committee by providing information on corporate and individual performance, market compensation data, and management's perspective on compensation matters. The Compensation Committee solicits and reviews our CEO's proposals with respect to program structures, as well as his recommendations for adjustments to annual total cash compensation opportunities, long-term incentive compensation opportunities, and other compensation-related matters for our executive officers, including our NEOs (except with respect to his own compensation), based on his evaluation of their performance for the prior year.

As part of our annual executive compensation process, our CEO reviews the performance of our other executive officers, including our other NEOs, based on each individual's level of success in accomplishing the business objectives established for such executive officer for the year and his or her overall performance during that year, and then shares these evaluations with, and makes recommendations to, the Compensation Committee for each element of compensation as described above. The annual business objectives for each executive officer are developed through mutual discussion and agreement between our CEO and the executive officers taking into account our business objectives, which are reviewed with our Board.

The Compensation Committee reviews and discusses with our CEO his proposals and recommendations and considers them as one factor in formulating and developing its recommendations to our Board with respect to the compensation of our executive officers, including our NEOs. Our CEO also attends meetings of our Board and the Compensation Committee at which executive compensation matters are addressed, except with respect to discussions involving his own compensation.

#### Role of Compensation Consultant
The Compensation Committee has the sole authority to retain an external compensation consultant to assist it by providing information, analysis, and other advice relating to our executive compensation program and the recommendations resulting from its annual executive compensation review, including the authority to approve the consultant's reasonable fees and other retention terms.

In 2025, the Compensation Committee engaged Compensia, Inc. ("Compensia"), a national compensation consulting firm, to continue to serve as its independent compensation consultant to advise on executive compensation matters, including competitive market pay practices for our executive officers, including

[**TABLE OF CONTENTS**](#TOC)

our NEOs, and with the data analysis and selection of the compensation peer group. Under the terms of the engagement, Compensia reports directly to the Compensation Committee and its chair, and serves at the discretion of the Compensation Committee, which reviews the engagement annually.

During 2025, Compensia attended the meetings of the Compensation Committee (both with and without management present) as requested and provided various services, including the following: the review, analysis, and updating of our compensation peer group; the review and analysis of the various compensation elements and opportunities of our executive officers, including our NEOs, and a review and analysis of the compensation of the non-employee members of our Board, as analyzed against competitive market data based on the companies in our compensation peer group and, in the case of our executive officers, selected broad-based compensation surveys; assessment of executive compensation trends; a review and analysis of our equity strategy and utilization; a compensation risk assessment; assistance with the preparation of the Compensation Discussion and Analysis and related executive compensation disclosure; and support on other ad hoc matters throughout the year.

In 2025, Compensia did not provide any other services to the Compensation Committee or to us.

The Compensation Committee has evaluated its relationship with Compensia to ensure that it believes that the firm is independent from management. This review process included a review of the services that Compensia provided, the quality of those services, and the fees associated with the services provided during 2025. Based on this review, as well as consideration of the factors affecting independence set forth in Exchange Act Rule 10C-1(b)(4) and the listing standards of the NYSE and such other factors as were deemed relevant under the circumstances, the Compensation Committee has determined that no conflict of interest was raised as a result of the work performed by Compensia.

#### Competitive Positioning
The Compensation Committee believes that peer group comparisons are useful guides to measure the competitiveness of our executive compensation program and related policies and practices. For purposes of assessing our executive compensation against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a select group of peer companies. This compensation peer group consists of technology companies that are similar to us in terms of revenue, market capitalization, and industry focus. The competitive data drawn from this compensation peer group is one of several factors that the Compensation Committee uses to formulate and develop its recommendations to our Board with respect to the compensation of our executive officers, including our NEOs.

On an annual basis, the Compensation Committee directs Compensia to review and update the compensation peer group used to analyze and establish the compensation of our executive officers to reflect current market conditions, to remove acquired or to be acquired companies and those that fall meaningfully above or below best practice size ranges, and to retain key peer companies identified by management and/or the Compensation Committee.

In identifying and selecting the companies that comprise each updated compensation peer group, Compensia considered the following primary criteria set forth in the table below.

The Compensation Committee uses data drawn from the companies in our compensation peer group, as well as data from custom data sets drawn from the Radford Global Technology Survey database (including a survey result of the available companies in our compensation peer group and a survey result of U.S. technology companies with revenues between $100 million and $1 billion), to evaluate the competitive market when developing its recommendations for the annual total direct compensation opportunities for our executive officers, including base salary, target annual cash bonus opportunities, and long-term incentive compensation opportunities.

As it deems appropriate, the Compensation Committee adjusts the composition of our compensation peer group if warranted, accounting for changes in both our business and the businesses of the companies in the peer group.

Compensation Elements

Generally, our executive compensation program consists of three principal elements—base salary, annual cash bonus opportunities, and long-term incentive compensation opportunities in the form of equity awards:

---

| | | | |
|:---|:---|:---|:---|
| **Element**  | **Type of <br> Element**  | **Compensation <br> Element**  | **Objective**  |
| Base Salary  | Fixed  | Cash  | Designed to attract and retain executive officers by providing fixed compensation amounts that are competitive in the market  |
| Annual Cash <br> Bonuses  | Variable  | Cash  | Designed to motivate our executive officers to achieve annual business objectives and provide financial incentives when we meet or exceed these annual objectives  |
| Long Term <br> Equity <br> Incentive <br> Compensation  | Variable  | Equity awards in <br> the form of PSU <br> awards and RSU <br> awards  | Designed to align the interests of our executive officers and our stockholders by motivating them to create sustainable long-term stockholder value |

---

We believe the total target direct compensation opportunities for our executive officers, including our NEOs, for 2025 were in line with market compensation paid for executives holding similar positions at the companies in our compensation peer group based on the Compensation Committee's general understanding of current compensation practices in the competitive market as reflected by data drawn from our compensation peer group and, in certain instances, selected broad-based compensation surveys.

#### Base Salary
Base salary represents the fixed portion of the compensation of our executive officers, including our NEOs, and is an important element of compensation intended to attract and retain highly talented individuals. Generally, we use base salary to provide each executive officer with a specified level of cash compensation during the year with the expectation that the executive officer will perform such individual's responsibilities to the best of the executive officer's ability and in our best interests.

Generally, we establish the initial base salaries of our executive officers through arm's-length negotiation at the time of hire, taking into account the individual's position, qualifications, experience and prior salary level, the base salaries of our other executive officers, and a competitive market analysis using data from the companies in our compensation peer group and, in certain instances, selected broad-based compensation surveys. Thereafter, the Compensation Committee reviews the base salaries of our executive officers each year as part of its annual review of our executive compensation program, with input from our CEO (except with respect to his own base salary) and develops recommendations for adjustments as it determines to be reasonable and necessary to reflect the scope of an executive officer's performance, individual contributions and responsibilities, position in the case of a promotion, and competitive market conditions.

In the first quarter of 2025, the Compensation Committee reviewed the base salaries of our executive officers, including our NEOs, taking into consideration a competitive market analysis prepared by Compensia and the recommendations of our CEO (except with respect to his own base salary), as well as the other factors described in "*Compensation-Setting Process—Setting Target Total Direct Compensation*" above. Following this review, the Compensation Committee recommended to our Board that they adjust the base salaries of certain of our executive officers to bring their base salaries to levels that were comparable to those of similarly-situated executives in the competitive marketplace. In recommending the adjustment to our Named Executive Officers' annual base salaries, the Compensation Committee considered the Company's business performance, individual executive performance and contributions, and competitive market compensation information. Subsequently, our Board approved these recommendations.

[**TABLE OF CONTENTS**](#TOC)

The base salaries of our Named Executive Officers as determined for 2025 were as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Named Executive Officer**  | **2024 Annual Base Salary**  | **2025 Annual Base Salary**  | **Percentage <br> Adjustment**  |
| **Mr. Zagorski**  | $650000 | $670000 | 3.1% |
| **Mr. Allais**  | $500000 | $515000 | 3.0% |
| **Ms. Eddleman**  | $500000 | $515000 | 3.0% |
| **Mr. Grimmig**  | $455000 | $480000 | 5.5% |

---

These base salaries were effective January 1, 2025.

The base salaries actually paid to our NEOs during 2025 are set forth below in the "*2025 Summary Compensation Table.*"

#### Annual Cash Bonuses
We use an annual cash bonus plan to motivate our executive officers, including our NEOs, to achieve our annual business goals. In February 2025, the Compensation Committee recommended, and our Board approved, the Bonus Plan for 2025 (the "2025 Bonus Plan") to provide incentives for our executive officers to meet or exceed certain business and financial objectives set by the Compensation Committee, after considering our 2025 annual operating plan.

#### Target Annual Cash Bonus Opportunities
In the first quarter of 2025, as part of its annual review of our executive compensation program, the Compensation Committee reviewed the target annual cash bonus opportunities of our executive officers, including our NEOs, taking into consideration a competitive market analysis prepared by its compensation consultant and the recommendations of our CEO (except with respect to his own target annual cash bonus opportunity), as well as the other factors described in "*Compensation-Setting Process—Setting Target Total Direct Compensation*" above. Following this review, the Compensation Committee recommended to our Board that they adjust the target annual cash bonus opportunities of certain of our executive officers to bring their target annual cash bonus opportunities to levels that were comparable to those of similarly situated executives in the competitive marketplace. In recommending the adjustment to our Named Executive Officers' target annual cash bonus opportunities, the Compensation Committee, considered the Company's business performance, individual executive performance, and competitive market compensation information, with the objective of aligning incentive opportunities with performance and market practice. Subsequently, our Board approved these recommendations.

The target annual cash bonus opportunities of our Named Executive Officers as determined for 2025 were as follows:

---

| | | |
|:---|:---|:---|
| **Named Executive Officer**  | **2025 Target Annual <br> Cash Bonus Opportunity <br> (as a percentage of base salary)**  | **2025 Target Annual <br> Cash Bonus Opportunity <br> ($)**  |
| **Mr. Zagorski**  | 100% | $670000 |
| **Mr. Allais**  | 75% | $386250 |
| **Ms. Eddleman**  | 100% | $515000 |
| **Mr. Grimmig**  | 65% | $312000 |

---

Potential annual cash bonuses for our Named Executive Officers under the 2025 Bonus Plan could range from zero to 140% of their target annual cash bonus opportunity.

#### 2025 Bonus Plan Performance Metrics
In February 2025, the Compensation Committee determined to use the same performance measures that it had selected for 2024 in the 2025 Bonus Plan:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

"Revenue" (weighted 50%) meant our total revenue for 2025 as determined under generally accepted accounting principles ("GAAP");

&nbsp;&nbsp;&nbsp;&nbsp; **•**

"Adjusted EBITDA" (weighted 30%) meant our earnings before interest, taxes, depreciation, and amortization, which is a non-GAAP financial measure, determined as described on page 53 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025; and

&nbsp;&nbsp;&nbsp;&nbsp; **•**

Our "Key Performance Indicators" (weighted 20%) included meeting or exceeding pre-established targets for Scibids revenue, meeting or exceeding a pre-established target of social measurement and social pre-bid revenue, meeting or exceeding a pre-established revenue per FTE equivalent target, and holding un-forecasted client churn to a preestablished target or less of advertising revenue, each as set forth in our annual operating plan.

With respect to the target annual cash bonus opportunities that could be earned by our executive officers, including our NEOs, in 2025, the bonus performance levels and potential payouts for the financial performance measures were set as follows:

---

| | | |
|:---|:---|:---|
| **Performance Measure**  | **Revenue**  | **Adjusted EBITDA**  |
| **Performance Threshold (%)**  | 95%  | 95%  |
| **Performance Threshold ($)**  | $687 million  | $224 million  |
| **Threshold Payout**  | 50%  | 50%  |
| **Performance Target (%)**  | 100%  | 100%  |

| **Performance Maximum (%)**  | 105%  | 105%  |
| **Performance Maximum ($)**  | $759 million  | $248 million  |
| **Maximum Payout**  | 150%  | 150%  |

---

(1) Bonus payouts are to be determined by linear interpolation between the threshold and target and target and maximum performance levels.

For 2025, the payout under the 2025 Bonus Plan was to be measured over the full year (measured from January 1<sup>st</sup> to December 31<sup>st</sup>).

#### 2025 Annual Cash Bonus Payout
In February 2026, the Compensation Committee reviewed our actual performance against the performance metrics approved by our Board in February 2025 to formulate its recommendations for the annual bonus awards to be paid to the participants in the 2025 Bonus Plan, including our NEOs.

Based on the 2025 performance measures approved by the Compensation Committee in February 2025, the Compensation Committee determined we achieved a revenue achievement percentage of 102%, an adjusted EBITDA achievement percentage of 105%, and a KPI achievement percentage of 75%, based on our average overall performance against all KPIs. These achievement percentages correlated to a 119% performance payout for revenue and 148% performance payout for adjusted EBITDA. Applying the relative weighting of each of these performance measures, this resulted in an aggregate performance payout percentage of 119%.

Accordingly, the Compensation Committee recommended to our Board that the following annual bonus awards be paid to our Named Executive Officers and, subsequently, our Board approved these recommendations.

The annual cash bonuses actually paid to our Named Executive Officers for 2025 are set forth below in the "*2025 Summary Compensation Table.*"

#### Long-Term Incentive Compensation
As a technology company that encounters significant competition for qualified personnel, long-term incentive compensation plays a critical role in our ability to attract, hire, motivate, and reward qualified and experienced executive officers. The use of long-term incentive compensation in the form of equity awards is necessary for us to compete for qualified executive officers without significantly increasing cash compensation, and we consider it to be the most important element of our executive compensation program. We use equity awards to incentivize and reward our executive officers, including our NEOs, for long-term corporate performance based on the value of our common stock and, thereby, to align their interests with the interests of our stockholders. The realized value of these equity awards bears a direct relationship to our stock price, and, therefore, these awards are an incentive for our executive officers to create sustainable value for our stockholders. Further, because our equity awards for our executive officers, including our NEOs, typically are earned and/or vest over a multi-year period, equity awards also help us retain our executive officers in a highly competitive market.

In the first quarter of 2025, the Compensation Committee recommended and our Board approved the grant of annual equity awards to our Named Executive Officers consisting of PSU awards with two-equally weighted performance-based and time-based vesting requirements that may be earned and settled for shares of our common stock and RSU awards with time-based vesting requirements that may be settled for shares of our common stock to motivate and reward our executive officers, including our Named Executive Officers, for sustained, long-term increases in the value of our common stock. PSU awards underscore and strengthen our "pay-for-performance" compensation philosophy because they are only earned upon achievement of a key performance goal that drives our business and our stockholder value. Therefore, these awards increase the alignment between the interests of our executive officers and stockholders. Since RSU awards have value to the recipient even in the absence of stock price appreciation, we believe that we are able to incentivize and retain our executive officers during periods of market volatility using fewer shares of our common stock than would be necessary if we used other equity vehicles, such as stock options, to provide our Named Executive Officers with an equity stake in the Company. Since the value of RSU awards increases with any increase in the value of the underlying shares, RSU awards also provide incentives to our executive officers that are aligned with the interests of our stockholders.

The Compensation Committee recommended that the dollar value of the PSU awards and the RSU awards should each comprise approximately 50% of each executive officer's 2025 equity award, and our Board approved such recommendations. The target value of these equity awards and the allocation between PSU awards and RSU awards were formulated by the Compensation Committee and approved by our Board after considering the intensely competitive market in which we operate, the value of our highly experienced executive team and the following factors:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the outstanding equity holdings of each executive officer (including the current economic value of his or her unvested equity holdings and the ability of these unvested holdings to satisfy our retention objectives);

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the projected impact of the proposed awards on our earnings;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the proportion of our total shares of common stock outstanding used for annual employee long-term incentive compensation awards (our "burn rate") in relation to the annual burn rate ranges of the companies in our compensation peer group and other recently-public technology companies;

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the potential voting power dilution to our stockholders in relation to the median practice of the companies in our compensation peer group; and

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the other factors described in "Compensation-Setting Process—Setting Target Total Direct Compensation" above.

The amounts of the equity awards are intended to provide competitively-sized awards and resulting annual target total direct compensation opportunities that our Board and the Compensation Committee believe are reasonable and appropriate taking into consideration the foregoing factors.

The aggregate dollar value of equity awards granted to our Named Executive Officers in March 2025 were as follows:

---

| | |
|:---|:---|
| **Named Executive Officer**  | **Long Term Incentive <br> Compensation Opportunity <br> ($)**  |
| **Mr. Zagorski**  | $9000000 |
| **Mr. Allais**  | $4000000 |
| **Ms. Eddleman**  | $3000000 |
| **Mr. Grimmig**  | $3000000 |

---

&nbsp;&nbsp;&nbsp;&nbsp; **•**

In the case of Mr. Zagorski, the reported value does not include the RSU award with a value of $2,500,000 granted to him in connection with the extension of his employment agreement, as described below.

&nbsp;&nbsp;&nbsp;&nbsp; **•**

The number of target PSUs and RSUs underlying each award was determined based on the 20-day trailing average closing price of our common stock as of the date of grant.

#### PSU Awards
As described above, the PSU awards granted in 2025 to our executive officers, including our NEOs, are subject to two distinct and equally weighted performance measures, with 50% of the economic value of such awards being Revenue PSU Awards and 50% being the Relative TSR PSU Awards.

The Compensation Committee determined to use our annual revenue as a performance measure for the Revenue PSU Awards, even though it has also been selected as a performance measure for our Bonus Plan for 2025, because of the critical importance of our ability to generate significant revenue growth at this stage of our development. The number of units that may be earned under the Revenue PSU Awards and the Relative TSR PSU Awards are determined as follows:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

<u>Revenue PSU Awards</u>—The number of units that may be earned under the Revenue PSU Awards is determined pursuant to the following schedule based on our revenue performance in 2025 (the "Revenue Performance Period"):

|:---|:---|:---|:---|:---|
| **Payout Level**  | **Minimum**  | **Threshold**  | **Target**  | **Maximum**  |

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

(1) The number of units earned is determined by linear interpolation between the threshold and target and target and maximum performance levels.

The Compensation Committee structured the Revenue PSU awards with a one-year performance period to strike a balance between its desire to use an absolute financial performance measure in the long-term incentive compensation for our executive officers and an acknowledgment of the difficulties inherent in establishing a long-term revenue-based performance goal in an uncertain macroeconomic environment and a volatile industry sector. The Compensation Committee carefully considered the implications of using a one-year performance period versus a longer period for this portion of the PSU awards and ultimately determined that any related issues were outweighed by the desire to avoid unintended consequences or limiting the Compensation Committee's flexibility as a result of outdated or inapplicable projected revenue estimates in future years.

Following completion of the Revenue Performance Period and certification of our actual results, the number of units actually earned and eligible to vest will be determined (the "Earned Revenue PSU Units"). Any units that did not become Earned Revenue PSU Units immediately terminate and are forfeited. Approximately 41.67% of the Earned Revenue PSU Units will vest and be settled upon the certification of our revenue performance level for 2025 and 8.33% of the remaining Earned Revenue PSU Units will vest and settle quarterly thereafter, contingent upon an executive officer's continued employment with or service to us through each applicable vesting date. Each Earned Revenue PSU Unit represents a contingent right to receive one share of our common stock for each earned unit.

&nbsp;&nbsp;&nbsp;&nbsp; **•**

<u>Relative TSR PSU Awards</u>—The number of units that may be earned under the Relative TSR PSU Awards will be compared to the Russell 3000 Index and measured over a three-year performance period ending December 31, 2027 (the "Relative TSR Performance Period"):

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Payout Level**  | **Minimum**  | **Threshold**  | **Target**  | **Maximum**  |
| Relative TSR Performance | Less than 33<sup>rd</sup> <br> percentile  | 33<sup>rd</sup> <br> percentile  | 55<sup>th</sup> <br> percentile  | 90<sup>th</sup> <br> percentile  |
| Units Earned<sup>(2)</sup> | 0%  | 50%  | 100%  | 200%  |

---

(2) The number of units earned is determined by linear interpolation between the threshold and target and target and maximum performance levels.

Following completion of the Relative TSR Performance Period and certification of our actual results, 100% of the earned Relative TSR PSU Units will vest and be settled, subject to the terms of the applicable award agreements. Each Earned Relative TSR PSU Unit represents a contingent right to receive one share of our common stock for each earned unit.

Upon a change-in-control of the Company:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the Revenue PSU awards will be converted to time-based RSU awards at the greater of target or actual performance, which will vest in accordance with their original vesting schedule; and

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the Relative TSR PSU Units will be converted to time-based RSU awards based on our performance through the closing of the change-in-control transaction based on the transaction price and vest in accordance with their original vesting schedule.

In the event a PSU holder's employment is terminated involuntarily or constructively within 12 months following a change in control, including our Named Executive Officers, then the holder's then-outstanding, unvested converted time-based PSUs will vest. In addition, the PSU awards are subject to payout upon the permanent disability or death of a PSU holder, including a Named Executive Officer, with payout limited to the target number of units if such event occurs during a performance period and to the actual number of units earned if such event occurs following the completion of the performance period.

#### RSU Awards
The RSU awards granted to our executive officers, including our NEOs in 2025 vest over a four-year period, with 6.25% of the total number of units subject to an award vesting on March 15, 2025 and 6.25%

[**TABLE OF CONTENTS**](#TOC)

of the total number of units subject to the award vesting quarterly thereafter for the remaining 15 quarters, contingent upon an executive officer's continued employment with or service to us through each applicable vesting date. Each unit granted pursuant to the RSU awards represents a contingent right to receive one share of our common stock for each unit that vests.

#### Additional RSU Award for Mr. Zagorski
Following our entry into an amended and restated employment agreement with Mr. Zagorski, effective as of July 21, 2025 (the "Amended and Restated Employment Agreement"), on August 19, 2025 our Board granted him a one-time RSU award with a grant date fair value of $2,500,000, with 8.33% of the total number of units subject to the award vesting on December 31, 2025 (the "2025 Vesting Date") and the remainder of the units vesting at a rate of 8.33% on each quarterly anniversary of the 2025 Vesting Date, subject to his continued employment with us through each applicable vesting date. Each unit granted pursuant to the RSU award represents a contingent right to receive one share of our common stock for each vested unit. The Board determined to grant this award to Mr. Zagorski in recognition of his continued service to the Company and his agreement to extend the term of his prior employment agreement with us.

The equity awards granted to our Named Executive Officers for 2025 are set forth below in the "*2025 Summary Compensation Table*" and the "*2025 Grants of Plan-Based Awards Table*."

#### Health and Welfare Benefits
Except with respect to the DoubleVerify Holdings, Inc. Deferred Compensation Plan (the "NQDC"), which is only available to the non-employee members of our Board and senior executives, our executive officers, including our NEOs, are eligible to participate in the same employee benefit plans, and on the same terms and conditions, as all other full-time, salaried U.S. employees, including payment of health care premiums for employees at the level of director and above. These benefits include medical, dental, and vision insurance, an employee assistance program, health and dependent care flexible spending accounts, basic life insurance, accidental death and dismemberment insurance, short-term and long-term disability insurance, commuter benefits, and reimbursement for mobile phone usage.

We provide a Section 401(k) defined contribution retirement savings plan for the benefit of our eligible employees located in the U.S., including our executive officers, under which participants are permitted to contribute a percentage of their compensation on a pre-tax basis, subject to limits in the U.S. Internal Revenue Code of 1986, as amended (the "Code"). We make fully vested matching contributions under the Section 401(k) plan, subject to the discretion of our Board. The terms of the Section 401(k) plan contemplate discretionary matching contributions to eligible participants of up to 75% of every dollar that such participants contribute up to 4% of their annual base salaries. Our executive officers, including our NEOs, are eligible to participate in the Section 401(k) plan on the same basis as our other employees.

We design our employee benefits programs to be affordable and competitive in relation to the market as well as compliant with applicable laws and practices. We adjust our employee benefits programs as needed based upon regular monitoring of applicable laws and practices and the competitive market.

#### Perquisites and Other Personal Benefits
Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide significant perquisites or other personal benefits to our executive officers, including our NEOs, except as generally made available to our employees or in situations where we believe it is appropriate to assist an individual in the performance of such person's duties, to make the executive officer more efficient and effective, and for recruitment and retention purposes.

In 2025, none of our NEOs received perquisites or other personal benefits in amounts equal to or greater than $10,000.

In the future, we may provide perquisites or other personal benefits in limited circumstances, such as those described in the preceding paragraph. All future practices with respect to perquisites or other personal benefits will be approved and subject to periodic review by the Compensation Committee.

Employment Agreements

We have entered into written employment agreements with each of our Named Executive Officers. We believe that these agreements are necessary to secure and retain the services of these individuals in a highly competitive job market.

Each of these employment agreements (including our amended and restated employment agreement with our CEO as described hereafter) does not have a specific term and provides for "at will" employment (meaning that either we or the Named Executive Officer may terminate the employment relationship at any time without cause). These employment agreements generally set forth the Named Executive Officer's base salary, target annual cash bonus opportunity, and eligibility to receive annual equity awards based upon performance and award guidelines as established by our Board or the Compensation Committee.

On July 21, 2025, we entered into the Amended and Restated Employment Agreement that provides for Mr. Zagorski's continued employment as our Chief Executive Officer. The Amended and Restated Employment Agreement does not have a finite term and may be terminated by either party on the terms and conditions prescribed therein, in the event of Mr. Zagorski's death or disability, or at any time by the mutual written agreement of the parties.

Pursuant to the Amended and Restated Employment Agreement, Mr. Zagorski will receive an annual base salary of at least $669,500. In addition, he is eligible for a target annual cash bonus opportunity equal to at least 100% of his annual base salary for each year during his continued employment by us. Mr. Zagorski was also granted a time-based RSU award with a grant date fair value of $2,500,000 and was eligible to participate in a Company-sponsored life insurance program in an amount equal to $3,000,000. However, Mr. Zagorski has not participated in such a program to date and no premiums were paid by the Company in 2025.

In addition, each employment agreement also includes non-compete and employee and customer non-solicitation covenants, effective during the Named Executive Officer's employment with us and for at least one-year post-termination. Further, each of our Named Executive Officers is also subject to intellectual property assignment and perpetual confidentiality provisions that protect our commercial interests.

These employment agreements also provide that each Named Executive Officer is eligible to receive severance payments and benefits upon a qualifying termination of employment, as more fully described in "Post-Employment Compensation" below.

For detailed descriptions of the employment arrangements with our Named Executive Officers, see "—*Narrative Disclosure to Summary Compensation Table—Employment Agreements*" and "—*Payments and Potential Payments upon Termination or Change in Control*" below.

Post-Employment Compensation

The employment agreements with our NEOs provide for certain protections in the event of specified involuntary terminations of employment (including a termination of employment by us "without cause" or a resignation of employment for "good reason," as such terms are defined in the employment agreements and which we refer to as a "qualifying termination"), in exchange for executing and not revoking our separation agreement and release of claims. The applicable provisions of the employment agreements provide reasonable compensation in the form of severance pay and certain limited benefits to a NEO if such individual leaves our employ under certain circumstances to facilitate the NEO's transition to new employment. Further, we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing NEO to sign a separation agreement and release of claims in a form and with terms acceptable to us providing for a general release of all claims as a condition to receiving post-employment compensation payments or benefits.

Mr. Zagorski's Amended and Restated Employment Agreement includes provisions related to severance payments and entitlements upon our termination of his employment for any reason other than "cause" (as defined in the Amended and Restated Employment Agreement), or his termination for "good reason" (as defined in the Amended and Restated Employment Agreement) as follows:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

In the event he terminates his employment without "good reason" after January 1 of a calendar year and prior to payment of the annual cash bonus in respect of the immediately preceding

[**TABLE OF CONTENTS**](#TOC)

calendar year, we will pay him the annual cash bonus for such preceding calendar year at the level accrued based on actual performance.

&nbsp;&nbsp;&nbsp;&nbsp; **•**

In the event his employment is terminated by us without "cause" or for "good reason," and subject to his execution and non-revocation of a general release and waiver of claims in our favor, he will be entitled to continued base salary for 12 months following termination of employment, as well as certain continued health benefits for two years following such termination. In addition, if the termination of employment occurs on or after January 1 of a calendar year and prior to payment of the annual cash bonus in respect of the immediately preceding calendar year, he will be entitled to payment of 100% of his target annual cash bonus opportunity.

If Mr. Allais's employment is terminated in a qualifying termination or by reason of his death or disability, the portion of his stock options that would otherwise have vested between the date of termination and the 12-month anniversary of the date of termination will accelerate and vest in full. In the case of Mr. Grimmig, if his employment is terminated by reason of his death or disability, all of Mr. Grimmig's unvested RSU awards will accelerate and fully vest.

The PSU awards granted to our Named Executive Officers are subject to payout upon the permanent disability or death of a Named Executive Officer, with payout limited to the target number of units if such event occurs during a performance period and to the actual number of units earned if such event occurs following the completion of the performance period.

Beginning with the equity awards granted to our executive officers, including our NEOs, in 2022, the vesting provisions of all stock options and RSU awards with time-based vesting requirements held by our Named Executive Officers are "double-trigger," which means that the vesting of these awards will generally accelerate and vest in full only if there is both a "change in control" of the Company (as defined in the 2021 Equity Plan and the DoubleVerify Holdings, Inc. 2017 Equity Incentive Plan) and, a qualifying termination of employment of the applicable Named Executive Officer. In addition, the PSU awards held by our Named Executive Officers are also "double-trigger" and will convert to time-based RSU awards only under such prescribed circumstances (as described above).

We believe that having in place reasonable and competitive post-employment compensation arrangements is essential to attracting and retaining highly qualified executive officers. The Compensation Committee does not consider the specific amounts payable under the post-employment compensation arrangements when developing its recommendations with respect to the annual compensation for our Named Executive Officers. We do believe, however, that these arrangements are necessary to offer compensation packages that are competitive.

#### Ms. Eddleman's Post-Employment Agreement
In connection with Ms. Eddleman's resignation, effective December 31, 2025, as Executive Vice President and Global Chief Commercial Officer, on September 15, 2025, we entered into an Executive Separation Agreement and a Consulting Agreement with her to provide for an orderly transition of her duties and responsibilities.

Under the Executive Separation Agreement and the Consulting Agreement, Ms. Eddleman continued in her role as Executive Vice President and Global Chief Commercial Officer at her existing compensation through December 31, 2025, and then transitioned her responsibilities as directed by the Company. Subject to her continued compliance with the restrictive covenants applicable to her, and her execution, reaffirmation, and non-revocation of a general release and waiver of claims against us, each of which has occurred, Ms. Eddleman was entitled to an annual cash bonus pursuant to the terms of the 2025 Bonus Plan at the level accrued by us. In addition, we agreed that Ms. Eddleman's service as a consultant would constitute continued service for purposes of the vesting of certain outstanding and unvested stock options, RSU awards, and PSU awards.

Ms. Eddleman's consulting arrangement has an initial term (the "Term") of approximately six months, which commenced on January 1, 2026, with the ability to extend for an additional period of six months based on mutual agreement, subject to certain prescribed termination triggers as set forth in the Executive Separation Agreement and the Consulting Agreement. During the Term, Ms. Eddleman shall serve as a

Senior Advisor to us to work on projects designated by our CEO. We have agreed to pay Ms. Eddleman $350 per hour for each hour she provides services during the Term.

For detailed descriptions of the post-employment compensation arrangements with our NEOs, as well as an estimate of the potential payments and benefits payable under these arrangements, see "*Potential Payments upon Termination or Change in Control*" below.

Non-Qualified Deferred Compensation Plan

We maintain the DoubleVerify Holdings, Inc. Deferred Compensation Plan (the "NQDC") to provide our executive officers and the non-employee members of our Board with an opportunity to defer base salary, cash fees paid to a non-employee director, cash bonus payments, and other compensation (including equity awards). In addition to elective deferrals, we may make discretionary contributions to be credited to the account of any or all participants, subject to the vesting requirements set forth in the NQDC (though to date we have not made any such contributions).

Each participant's deferred compensation account is credited with an investment return determined as if the account was invested in one or more investment funds. Each participant elects the investment funds in which such participant's account will be deemed to be invested. Distributions of vested account balances are made upon death, disability, separation from service, or a specified date. Distributions are to be made in a single cash payment or, at the election of the participant, in annual installments for a period of between two and 10 years in the case of a separation from service or in-service distribution.

Our obligations under the NQDC are general unsecured promises to pay deferred compensation in the future to eligible participants in accordance with the terms of the NQDC from our general assets. Distributions from the NQDC are governed by the Code and the NQDC. We may, at any time, in our sole discretion, terminate the NQDC or amend or modify the NQDC, in whole or in part, except that no such termination, amendment, or modification will have a substantive effect on the benefits provided under the NQDC.

For more information on the participation of our NEOs in the NQDC, see "*Nonqualified Deferred Compensation*" below.

Other Compensation Policies

#### Equity Award Grant Practices
We do not grant equity awards in anticipation of the release of material, nonpublic information or time the release of material, nonpublic information based on equity award grant dates, vesting events, or sale events. During 2025, we did not grant equity awards to our Named Executive Officers during the four business days prior to or the one business day following the filing of our periodic reports or the filing or furnishing of a current report on Form 8-K that disclosed material nonpublic information. We have not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation for Named Executive Officer equity awards in 2025. The annual equity awards granted to our Named Executive Officers are approved in the first fiscal quarter of each year to provide our Board and the Compensation Committee with a complete view of year end results and a more refined forecast when approving our performance goals, which improves their ability to set appropriately calibrated goals to more closely align pay with performance.

#### Hedging and Pledging Policies
Our Policy on Trading in Securities requires all directors, officers, and employees of the Company, and their immediate family members and other persons living in their households ("Company Associates"), to consult our Chief Legal Officer prior to engaging in any hedging or pledging transactions involving our equity securities. Any request for pre-clearance of a hedging or similar arrangement must be submitted to our Chief Legal Officer at least 30 days before the proposed execution of documents evidencing the proposed transaction. Our Chief Legal Officer will then determine whether the transaction may proceed and, if so, assist in complying with the SEC's reporting requirements. Any Company Associate proposing to pledge our equity securities as collateral for a loan must submit a request for pre-clearance to our Chief Legal Officer at least two weeks prior to the proposed execution of documents evidencing the proposed pledge. Our Chief Legal Officer will then determine whether the transaction may proceed. Our

[**TABLE OF CONTENTS**](#TOC)

Policy on Trading in Securities prohibits our Company Associates from engaging in short sales and transactions in puts, calls, or other derivative securities (whether on an exchange or in any other organized market) with respect to our equity securities.

#### Stock Ownership Guidelines
The Board has established stock ownership guidelines to further align the long-term interests of our executive officers and non-employee directors with those of our stockholders and promote the Company's commitment to sound corporate governance. Our stock ownership guidelines require that our executive officers own qualifying equity having an aggregate value equal to a multiple of the executive officer's annual base salary or non-employee director's annual board cash retainer as follows:

![[MISSING IMAGE: bc_stockownership-pn.jpg]](bc_stockownership-pn.jpg)

The types of equity that are eligible for calculation in the guidelines include shares of our common stock held outright (including shares beneficially owned unless the individual disclaims beneficial ownership), shares held in the DoubleVerify Holdings, Inc. 2021 Employee Stock Purchase Plan (the "ESPP"), shares underlying any earned, unsettled PSU awards (including vested shares held in the NQDC), and shares underlying any unsettled RSU awards. Executive officers are required to hold 50% of the shares of our common stock acquired as a result of exercise or settlement of compensatory awards (net of any shares withheld for taxes) until these stock ownership guidelines have been met.

Compliance with these stock ownership guidelines is reviewed at least annually by the Compensation Committee.

#### Compensation Recovery ("Clawback") Policy
We maintain the DoubleVerify Holdings, Inc. Clawback Policy (the "Clawback Policy") which complies with the requirements of Exchange Act Rule 10D-1 and the applicable NYSE listing standards. The Clawback Policy provides for the mandatory prompt recovery of erroneously awarded incentive-based compensation from our current and former executive officers (as defined in Exchange Act Rule 10D-1) in the event we are required to prepare an accounting restatement, in accordance with the Final Clawback Rules. The recovery of such compensation applies regardless of whether an executive officer engaged in misconduct or otherwise caused or contributed to the requirement of an accounting restatement. Under the Clawback Policy, the Company may recover from the current and former executive officers erroneously awarded incentive-based compensation received within a lookback period of the three completed fiscal years preceding the date on which we are required to prepare an accounting restatement. This policy applies with respect to all incentive-based compensation received on or after October 2, 2023.

In addition, we maintain a compensation recovery and forfeiture policy that provides for recovery of all excess "incentive compensation" (as defined therein) paid or awarded to any current or former "executive officer" (as defined in Section 16 of the Exchange Act) and any other current or former employee who has received an equity award (a "Covered Person") if:

&nbsp;&nbsp;&nbsp;&nbsp; **•**

we are required to prepare an accounting restatement of our financial results due to material noncompliance with any financial reporting requirement under the U.S. securities laws caused by the fraud, misconduct, or gross negligence of a Covered Person;

the Compensation Committee determines that any Covered Person received incentive compensation based on inaccurate financial information or other inaccurate performance metric criteria; or

&nbsp;&nbsp;&nbsp;&nbsp; **•**

the Compensation Committee determines that any Covered Person committed misconduct that has or might reasonably be expected to cause reputational or other harm to us, committed misconduct or a material error that causes or might be reasonably expected to cause significant financial or reputational harm to us or was improper or grossly negligent, including in a supervisory capacity, in failing to identify, escalate, monitor, or manage, in a timely manner and as reasonably expected, risks material to us.

This latter policy applies with respect to cash incentive compensation paid after April 15, 2021 and equity incentive compensation granted after such date and, to the extent agreed by a Covered Person or as otherwise permitted by applicable law, incentive compensation that was granted prior to such date.

#### Tax and Accounting Considerations
The Compensation Committee takes the applicable tax and accounting requirements into consideration in designing and overseeing our executive compensation program.

#### Deductibility of Executive Compensation
Under Section 162(m) of the Code, compensation paid to our "covered executive officers" (which include our CEO and CFO), will not be deductible to the extent it exceeds $1 million. While the Compensation Committee considers the deductibility of awards as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions, as noted above, and retains the flexibility to award compensation that it determines to be consistent with the goals of our executive compensation program even if the awards are not deductible by us for tax purposes.

#### Accounting for Stock-Based Compensation
The Compensation Committee takes accounting considerations into account in designing compensation plans and arrangements for our executive officers and other employees. Chief among these is Financial Accounting Standards Board Accounting Standards Codification Topic 718 ("ASC Topic 718"), the standard which governs the accounting treatment of certain stock-based compensation. Among other things, ASC Topic 718 requires us to record a compensation expense in our income statement for all equity awards granted to our executive officers and other employees. This compensation expense is based on the grant date "fair value" of the equity award and, in most cases, will be recognized ratably over the award's requisite service period (which, generally, will correspond to the award's vesting schedule). This compensation expense is also reported in the compensation tables below, even though recipients may never realize any value from their equity awards.

#### Compensation Committee Report
The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis (CD&A) contained in this Proxy Statement. Based on this review and discussion, the Compensation Committee has recommended to the Board that the CD&A be included in this Proxy Statement.

Submitted by the Compensation Committee of the Company's Board of Directors:

(1) This amount represents the aggregate grant date fair value of PSUs and RSUs granted during the applicable fiscal year, assuming target performance for all PSUs. Assuming maximum performance, the grant date fair value of the 2025 PSUs would be $5,044,836 for Mr. Zagorski; $2,242,172 for Mr. Allais; $1,681,598 for Ms. Eddleman; and $1,681,598 for Mr. Grimmig. No annual equity awards were granted to our executive officers in 2024 due to a change in the timing of our annual grant practice. As a result, the "Stock Awards" column reflects no equity award value for that year, and the "Total" column reflects significantly lower total compensation compared to 2025 and 2023. Grant date fair value is calculated in accordance with FASB ASC Topic 718 and does not represent the value actually realized, or that may ultimately be realized, by our NEOs. No option awards were granted to our NEOs in 2025, 2024 or 2023.

(2) For 2025, 2024 and 2023, the amount in this column represents bonuses relating to full year Company performance.

(3) Amounts reported in the "All Other Compensation" column for our NEOs include the items set forth in the table below, as applicable to each NEO.

[**TABLE OF CONTENTS**](#TOC)

Our NQDC plan provides our executive officers and members of our Board with an opportunity to defer base salary, cash fees paid to a non-employee director, cash bonus payments and other compensation (including equity awards). In addition to elective deferrals, the Company may make discretionary contributions to be credited to the account of any or all participants, subject to the vesting requirements set forth in the NQDC (though to date we have not made any such contributions). Each participant's deferred compensation account is credited with a notional investment return based on various investment funds that are generally the same as the investment funds available under our tax qualified plan. Distributions of vested account balances are made upon death, disability, separation from service, or a specified date. Distributions are to be made in a single cash payment or, at the election of the participant, in annual installments for a period of between two and 10 years in the case of a separation from service or in-service distribution.

Please see the discussion of the NQDC in our Compensation Discussion & Analysis for more details about the operation of the plan.

#### Payments and Potential Payments upon Termination or Change in Control
Employment Agreement Obligations

#### Mark Zagorski
Mr. Zagorski's Amended and Restated Employment Agreement, effective as of July 21, 2025, does not have a fixed term and may also be terminated at any time by either party. The employment agreement provides for severance benefits upon certain terminations of employment. In particular, if Mr. Zagorski's employment is terminated by us without "cause" or if he resigns his employment for "good reason" (as such terms are defined in his employment agreement), which we refer to as a "qualifying termination," subject to his execution and non-revocation of a general release of claims, Mr. Zagorski is entitled to receive his continued base salary as in effect at the time of termination for 12 months, as described in the table "Summary of Estimated Payments and Benefits" below.

In addition, Mr. Zagorski will be entitled to certain continued health benefits for two years following such termination. If such qualifying termination occurs on or after January 1 of a calendar year and prior to payment of the annual cash bonus in respect of the immediately preceding calendar year, he will be entitled to payment of 100% of his target annual cash bonus opportunity for such preceding year.

#### Nicola Allais, Julie Eddleman and Andrew Grimmig
The employment agreements of Mr. Allais and Mr. Grimmig do not provide a fixed term and may be terminated at any time by either party. As noted above, Ms. Eddleman resigned from her position effective December 31, 2025.

If the employment of Mr. Allais or Mr. Grimmig is terminated by us without cause or by the applicable executive for good reason (which we refer to as a "qualifying termination"), the applicable executive will be entitled to receive amounts as described in the table "Summary of Estimated Payments and Benefits" below.

#### Treatment of Equity Awards Generally
In the event that we terminate an NEO's employment for "cause", or an NEO breaches a restrictive covenant by which he or she is bound, all of such NEO's unvested and vested stock options, PSUs and RSUs will be immediately cancelled and forfeited.

All of our current equity-based awards provide for "double-trigger" vesting in connection with a change in control. Under this structure, stock options, PSUs and RSUs granted in 2022 and thereafter do not automatically accelerate or vest solely upon a change in control. Instead, vesting will accelerate only if the NEO's employment is terminated by the Company without cause or by the NEO for good reason within one year following the change in control. We do not provide any excise tax payments (or "gross-ups") in connection with a change in control of the Company and have no such obligations in place with respect to any of our executive officers, including our Named Executive Officers.

(1) Reflects the base salary in effect as of December 31, 2025.

(2) Reflects employer and employee portion of continued medical, dental and vision insurance coverage for each NEO at rates currently in effect.

(3) Upon a "qualifying termination," Mr. Zagorski is entitled to receive an amount equal to his annual base salary, payable in accordance with the Company's normal payroll practices over 12 months, and also continued medical, dental and vision insurance coverage for 24 months at active employee rates. Additionally, upon a qualifying termination he will receive an amount equal to 100% of his target bonus payable in accordance with the Company's normal payroll practices as the base salary component of his severance. In addition, upon a "qualifying termination" in connection with a change in control, all then-outstanding and unvested PSUs will vest.

(4) If an NEO is terminated by reason of death or disability, all then-outstanding and unvested PSUs will vest.

(5) Upon a qualifying termination, Mr. Allais is entitled to receive an amount equal to 12 months of his base salary, payable in semi-monthly installments over 12 months, and also continued medical, dental and vision insurance coverage for 12 months at active employee rates. In addition, upon a "qualifying termination" in connection with a change in control, all then-outstanding and unvested PSUs will vest.

(6) Reflects Ms. Eddleman's fiscal year 2025 annual bonus, which was determined following the end of the fiscal year and paid in February 2026 in accordance with the Company's normal bonus payment practices for executives, including our NEOs. Following termination, Ms. Eddleman will provide consulting services beginning January 1, 2026 at a rate of $350 per hour. Because the consulting fees represent compensation for future services at market rates, the amounts payable under the consulting agreement are not included in the termination payments table.

(7) Reflects the value of stock options, RSUs and PSUs that continue to vest during Ms. Eddleman's consulting term pursuant to the consulting agreement. No acceleration occurs upon termination of employment. The value reflects the number of stock options, RSUs and PSUs scheduled to vest during the consulting period multiplied by the closing price of the Company's common stock on December 31, 2025.

(8) If Ms. Eddleman's consulting term terminates due to death or disability, any then-outstanding PSUs that were scheduled to vest during the consulting term will become fully vested.

(9) Upon a qualifying termination, Mr. Grimmig is entitled to receive an amount equal to six months of his base salary, payable in semi-monthly installments over six months, and also continued medical, dental and vision insurance coverage for six months at active employee rates.

#### Pay Ratio Disclosure
As required by SEC rules, we are providing the information below to explain the relationship between the annual total compensation of Mr. Zagorski, who served as the Company's Chief Executive Officer in 2025, and the annual total compensation of the median employee of the Company, excluding our CEO. Following a review of our employee population and compensation programs, we concluded that there were no material changes during 2025 that would significantly impact our pay ratio disclosure. As a result, we continued to apply our established methodology to identify the median employee for purposes of the 2025 calculation.

The median annual total compensation disclosed below is based on the Company's global workforce and is not designed to capture the median compensation of the Company's U.S. employees. Our compensation philosophy is to pay competitively to market and provide fair compensation regardless of the locale. The compensation approach used to determine compensation for our broader workforce is the same approach we use when setting CEO pay, including consideration of pay competitiveness and the use of performance-based incentives that reward exceptional business performance in each jurisdiction consistent with market practice.

For 2025, the annual total compensation of our median employee was $213,401. This includes base pay, 2025 bonus, 2025 equity award and an employer retirement contribution. Mr. Zagorski's annual total compensation for 2025, as reported under the "Total" column in the 2025 Summary Compensation Table, was $11,814,232. For 2025, as described in "—*Compensation Elements—Long-Term Equity Incentive Compensation*" above, no annual equity awards were granted to our executive officers, including our CEO. Based on this information, for 2025, the ratio of the compensation of the CEO to the median annual total compensation of all other employees was estimated to be 55.36 to 1.

[**TABLE OF CONTENTS**](#TOC)

We believe our pay ratio presented above is a reasonable estimate. The SEC rules for identifying the median employee and calculating the pay ratio allow companies to use different methodologies, exemptions, estimates and assumptions that reflect their employee populations and compensation practices. As a result, our pay ratio may not be comparable to the pay ratio reported by other companies.

Relationship Between Pay and Performance

We believe the "Compensation Actually Paid" in each of the years reported above and over the five-year cumulative period are reflective of the Compensation Committee's emphasis on "pay-for-performance" as the "Compensation Actually Paid" fluctuated year-over-year, primarily due to the results of our stock performance.

The following chart sets forth the relationships between Compensation Actually Paid to our PEO, the average of Compensation Actually Paid to our Non-PEO NEO's, and the cumulative TSR from the Company's IPO through the end of the five most recently completed fiscal years for the Company and the NASDAQ Composite Index TSR.

[**TABLE OF CONTENTS**](#TOC)

 **Board and Corporate Governance Practices** 

<br> We believe that effective corporate governance policies and practices help the Company deliver sustainable, long-term value to our stockholders.

These policies and practices are contained in our governance documents, including our Certificate of Incorporation, Amended and Restated Bylaws (the "Bylaws"), Corporate Governance Guidelines and committee charters. This section describes the key features of the Board practices and corporate governance program.

#### Board Leadership Structure
The Board is currently composed of ten directors. Our Certificate of Incorporation provides for a classified board of directors, with members of each class serving staggered three-year terms. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. We currently have three directors in Class I, three directors in Class II and four directors in Class III. The terms of directors in Classes I, II, and III end at the annual meetings of stockholders in 2028, 2026, and 2027, respectively. The Board is led by our non-executive Chairperson, R. Davis Noell. At this time, the Board believes the classified board structure is in the best interest of the Company. The Board has implemented measures to ensure accountability of our directors, including the adoption of our Code of Ethics. Additionally, to enhance accountability, the Board has pledged to sunset provisions in our Certificate of Incorporation and Bylaws requiring a classified board and certain supermajority voting features within the next two years.

With respect to the roles of Chairperson of the Board and Chief Executive Officer, our Corporate Governance Guidelines provide that the roles may be separated or combined, and our Board is able to exercise its discretion in combining or separating these positions as it deems appropriate. Our Corporate Governance Guidelines provide our Board with flexibility to modify our leadership structure in order to serve the best interests of the Company. Our Corporate Governance Guidelines provide that if the Board decides to combine the roles of Chairperson and Chief Executive Officer, a lead director will be appointed annually by the independent directors. The Board will continue to review its leadership structure to evaluate whether the structure remains appropriate for the Company.

In connection with our IPO, we and the Providence Investor entered into a stockholder's agreement (the "Stockholder's Agreement") pursuant to which, among other matters, the Providence Investor has the right to designate nominees for the Board (the "Providence Designees"), subject to the maintenance of specified ownership requirements. See "Certain Relationships and Related Party Transactions—Relationship with Providence—Stockholder's Agreement."

The number of members on the Board may be fixed by resolution adopted from time to time by the Board. Subject to the Stockholder's Agreement, any vacancies or newly created directorships may be filled only by the affirmative vote of a majority of directors then in office, even if less than a quorum, or by a sole remaining director. Each director shall hold office until his or her successor has been elected and qualified, or until his or her earlier death, resignation or removal. With respect to any vacancy of a Providence Designee, the Providence Investor will have the right to designate a new director for election by a majority of the remaining directors then in office.

#### Board Composition
Set forth below is biographical information as well as background information relating to each nominee's and continuing director's business experience, qualifications, attributes and skills and why the Board and Nominating and Governance Committee believe each individual is a valuable member of the Board.

#### Director Nominations
Nominations for election as a director at our annual meetings of stockholders may be made by the Board in the Company's notice of meeting or any supplement thereto, or by a stockholder or stockholders in compliance with the advance notice provisions set forth in the Company's Bylaws. The Nominating and Governance Committee recommends director nominees and may identify potential nominees through a variety of means, including referrals from current directors, executive officers and stockholders or recommendations from professional search firms. In recommending candidates for nomination by the Board, the Nominating and Governance Committee takes into consideration the candidate's skills, judgment and diversity of experience, NYSE listing requirements, the needs of the Board and any other criteria the Board may establish from time to time. The Nominating and Governance Committee will consider candidates recommended by stockholders.

#### Director Independence
As required by NYSE rules, the Board considers annually whether each of its members is "independent" for purposes of NYSE rules. Those rules provide that a director is "independent" if the Board determines that the director does not have any direct or indirect material relationship with the Company.

The Board has affirmatively determined, after considering all of the relevant facts and circumstances, that Laura B. Desmond, Lucy S. Dobrin, Sundeep Jain, R. Davis Noell, Rosie Perez, Jennifer Storms, Gary Swidler, Kelli Turner and Scott Wagner are "independent" as defined under NYSE rules, and that Rosie Perez, Gary Swidler and Kelli Turner are "independent" as defined under Rule 10A-3 under the Exchange Act. This determination was based, in part, on detailed information provided by each director regarding his or her business and professional relationships, and those of his or her family members, with the Company and those entities with which we have significant business or financial interactions. As of the date of this Proxy Statement, each of the Audit Committee, Compensation Committee and Nominating and Governance Committee are entirely composed of independent directors.

#### Board Meetings and Attendance at the Annual Meeting
The Board held five meetings during the year ended December 31, 2025. Each of our current directors attended at least 75% of the total number of meetings of the Board and any committees of which such director was a member. Currently, we do not maintain a formal policy regarding director attendance at the Annual Meeting; however, directors are encouraged to attend our annual meetings of stockholders.

Executive sessions, which are meetings of the non-management members of the Board, are regularly held. In addition, at least once a year, the independent directors are afforded the opportunity to meet in a private session that excludes management and non-independent directors. At each of these meetings, the non-management and independent directors in attendance, as applicable, will determine which member will preside at such session. Committees of the Board, as described more fully below, also meet periodically in executive sessions.

#### Corporate Governance Guidelines
The Board has adopted Corporate Governance Guidelines to address significant corporate governance issues. A copy of these guidelines is available without charge at https://ir.doubleverify.com/ corporate-governance/governance-documents. These guidelines provide a framework for our corporate governance initiatives and cover topics including, but not limited to, director qualification and responsibilities, board composition, director compensation, management and succession planning and self-evaluation. The Board and Nominating and Governance Committee are responsible for overseeing and reviewing the guidelines and reporting and recommending to the Board any changes to the guidelines.

#### Code of Business Conduct, Code of Ethics and Anti-Human Trafficking and Anti-Modern Slavery Code of Conduct
We have a Code of Business Conduct and Code of Ethics that apply to all of our officers, employees, and directors. The Code of Business Conduct and the Code of Ethics address matters such as conflicts of

interest, confidentiality, business practices, and compliance with laws and regulations. The Code of Business Conduct and the Code of Ethics are available without charge at https://ir.doubleverify.com/ corporate-governance/governance-documents. DoubleVerify and all its employees believe that human trafficking and modern slavery have no place in our society. DoubleVerify expressly prohibits the use of involuntary labor, internally, as it relates to our workforce or externally, within our supply chain. The prohibition is explicitly stated in our Code of Conduct. More information on our Anti-Human Trafficking and Anti-Modern Slavery Code of Conduct can be found at doubleverify.com.

#### Hedging and Pledging Policies
Our Policy on Trading in Securities requires all directors, officers and employees of the Company, and their immediate family members and other persons living in their households ("Company Associates"), to consult the Chief Legal Officer prior to engaging in any hedging or pledging transactions involving the Company's securities. Any request for pre-clearance of a hedging or similar arrangement must be submitted to the Chief Legal Officer at least thirty days before the proposed execution of documents evidencing the proposed transaction. The Chief Legal Officer will then determine whether the transaction may proceed and, if so, assist in complying with the SEC's reporting requirements. Any Company Associate proposing to pledge the Company's securities as collateral for a loan must submit a request for pre-clearance to the Chief Legal Officer at least two weeks prior to the proposed execution of documents evidencing the proposed pledge. The Chief Legal Officer will then determine whether the transaction may proceed. Our Policy on Trading in Securities prohibits Company Associates from engaging in short sales and transactions in puts, calls or other derivative securities (whether on an exchange or in any other organized market) with respect to the Company's securities.

#### Board Committees
The Board maintains an Audit Committee, a Compensation Committee and a Nominating and Governance Committee. Below is a brief description of our committees. The following table shows the current members of each committee and the number of meetings held during 2025.

#### Compensation Committee Interlocks and Insider Participation

#### Selection of Nominees for Election to the Board
Our Corporate Governance Guidelines provide that, subject to the requirements of the Stockholder's Agreement, the Board will select new director candidates based on the recommendations of the Nominating and Governance Committee. The Nominating and Governance Committee will identify and recommend to the Board candidates who the Nominating and Governance Committee believes are qualified and suitable to become members of the Board consistent with the criteria for selection of new directors adopted from time to time by the Board. Our Board believes that it should be a well-rounded body and seeks to promote board membership that reflects a variety of professional backgrounds, educations, skills, experience, and other individual qualities and attributes that contribute to the total mix of

viewpoints and experience. Our Nominating and Governance Committee considers a broad range of backgrounds and experiences and the Board's current composition and needs, including any requirements of independence, as well as the skills, judgment and breadth of experience of candidates, expertise, and considers the general qualifications of the potential nominees, such as strong values and discipline, high ethical standards, a commitment to full participation on the Board and its committees, and relevant career experience, along with other skills and characteristics that meet the current needs of the Board. The Board will consider the following criteria for director qualification: (i) the nominee's independence, judgment, strength of character, ethics and integrity; (ii) the nominee's business or other relevant experience and skills and knowledge useful to the oversight of the Company's business; (iii) alignment of the skills, experience, and diverse perspectives of the Board as a whole with the Company's needs; and (iv) whether a nominee has sufficient time to carry out the responsibilities of a director.

In identifying candidates for election to the Board, the Nominating and Governance Committee may consider nominees recommended by directors, stockholders, and other sources. The Nominating and Governance Committee reviews each candidate's qualifications, including whether a candidate possesses any of the specific qualities and skills desirable in certain members of the Board. Evaluations of candidates generally involve a review of background materials, internal discussions, and interviews with selected candidates as appropriate. Upon selection of a qualified candidate, the Nominating and Governance Committee would recommend the candidate for consideration by the full Board. The Nominating and Governance Committee may engage consultants or third-party search firms to assist in identifying and evaluating potential nominees.

The Nominating and Governance Committee will consider director candidates proposed by stockholders on the same basis as recommendations from other sources. Any stockholder who wishes to recommend a prospective candidate for the Board for consideration by the Nominating and Governance Committee may do so by submitting the name and qualifications of the prospective candidate in writing to the following address: DoubleVerify Holdings, Inc., c/o Corporate Secretary, 462 Broadway, New York, New York 10013. Any such submission should also describe the experience, qualifications, attributes and skills that make the prospective candidate a suitable nominee for the Board. Our Bylaws set forth the requirements for direct nomination by a stockholder of persons for election to the Board.

Pursuant to the Stockholder's Agreement, the Providence Investor is currently entitled to nominate (or cause to be nominated) at least 5% of the total number of directors comprising the Board. See "Certain Relationships and Related Party Transactions" for additional information.

#### Communications with the Board
Any stockholder or interested party who wishes to communicate with the Board as a whole, the independent directors, or any individual member of the Board or any committee of the Board may e-mail or write to the Company at: DoubleVerify Holdings, Inc., c/o Corporate Secretary, 462 Broadway, New York, New York 10013 and corporatesecretary@doubleverify.com.

The Board has designated the Company's Corporate Secretary (the "Secretary") as its agent to receive and review written communications addressed to the Board, any of its committees, or any board member or group of members. The Secretary may communicate with the sender for any clarification. In addition, the Secretary will promptly forward to the Chairperson of the Audit Committee any communication alleging legal, ethical or compliance issues by management or any other matter deemed by the Secretary to be potentially material to the Company. As an initial matter, the Secretary will determine whether the communication is a proper communication for the Board. The Secretary will not forward to the Board, any committee or any director communications of a personal nature or not related to the duties and responsibilities of the Board, including, without limitation, junk mail and mass mailings, business solicitations, routine customer service complaints, new product or service suggestions, political campaign or election materials, opinion survey polls or any other communications deemed by the Secretary to be immaterial to the Company.

Separately, the Company has established a whistleblower policy for the receipt, retention, and treatment of complaints received by the Company regarding suspected violations of our Code of Ethics, policies or

the law, including questionable accounting, internal accounting controls or auditing matters, and the confidential, anonymous submission by associates of the Company of concerns regarding such matters.

#### Risk Oversight
The Board as a whole has responsibility for overseeing our risk management. The Board exercises this oversight responsibility directly and through its committees. The oversight responsibility of the Board and its committees is informed by reports from our management team and from our internal audit department that are designed to provide visibility to the Board about the identification and assessment of key risks and our risk mitigation strategies. The full Board has primary responsibility for evaluating strategic and operational risk management, and succession planning, and reviews our enterprise risk assessment on at least an annual basis. Our Audit Committee has the responsibility for overseeing our major financial and accounting risk exposures and the steps our management has taken to monitor and control these exposures, including policies and procedures for assessing and managing risk, including oversight on compliance related to legal and regulatory exposure and meets regularly with our Chief Legal Officer. Our Audit Committee also reviews and discusses with management the adequacy and effectiveness of the Company's information and technology security policies and the internal controls regarding information and technology security, cybersecurity and privacy related areas. Our Compensation Committee evaluates risks arising from our compensation policies and practices, as more fully described below. The Audit Committee and Compensation Committee provide reports to the full Board regarding these and other matters.

#### Compensation Risk Assessment
Our overall compensation program is designed to mitigate the potential for rewarding excessive risk-taking that may produce short-term results that appear in isolation to be favorable, but which, in fact, may undermine the successful execution of our long-term business strategy and erode stockholder value. The Compensation Committee has reviewed our incentive compensation programs and discussed these with its compensation consultant, including both broad-based programs and our executive compensation program. Based on this review, the Compensation Committee has determined that the risks arising from its compensation programs are not reasonably likely to have a material adverse effect on the Company.

#### Other Governance Policies
A description of our Compensation "Clawback" and Forfeiture Policy and Stock Ownership Guidelines can be found in the "Compensation Discussion and Analysis" found elsewhere in this Proxy Statement.

#### Corporate Social Responsibility
We are committed to conducting our business in a responsible manner and believe that we have an obligation to evaluate corporate social responsibility ("CSR") considerations as we make strategic decisions and understand how those decisions impact our all of our stakeholders, which include our investors, employees, customers, partners and the global communities and locations in which we operate. Our Board recognizes the importance of these responsibilities and the Nominating and Governance Committee oversees our initiatives.

#### People Experience
At DV, we respect differences and are committed to delivering an exceptional people experience. We empower each employee to bring their authentic self to the workplace and their role. Being Authentically DV leads to successful teams and better business results.

Our values (Passion, Accountability, Collaboration, Trailblazing), are integral to our business strategy and focus on the following areas:

Continually improve our environmental performance by periodically reviewing our environmental policy in planning our current and future activities.

#### Privacy, Security & Data Governance
Trust is foundational to the lasting partnerships we've built with global advertisers, as well as the world's leading programmatic and social platforms, and publishers. It is also the guiding principle DV follows as we develop and expand our privacy, security, risk and data governance programs. The privacy and security landscape of the advertising ecosystem is constantly evolving. That is why we are committed to providing privacy-forward, secure tools designed to promote the success of our customers while upholding the rights of individuals. Our commitment to transparency has enabled us to bolster our reputation of trustworthiness.

 **Certain Relationships and Related Person Transactions** 

<br> #### Policies and Procedures for Related Person Transactions
The Board has approved policies and procedures with respect to the review and approval of certain transactions between us and a "Related Person," or a "Related Person Transaction," which we refer to as our "Related Person Transaction Policy." Pursuant to the terms of the Related Person Transaction Policy, our Board, acting through our Audit Committee, must review and decide whether to approve or ratify any Related Person Transaction. Any Related Person Transaction is required to be reported to our legal department, which will then determine whether it should be submitted to our Audit Committee for consideration. The Audit Committee must then review and decide whether to approve any Related Person Transaction.

For the purposes of the Related Person Transaction Policy, a "Related Person Transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we (including any of our subsidiaries) were, are or will be a participant and the amount involved exceeds $120,000, and in which any Related Person had, has or will have a direct or indirect interest.

A "Related Person," as defined in the Related Person Transaction Policy, means any person who is, or at any time since the beginning of our last fiscal year was, a director or executive officer of DoubleVerify or a nominee to become a director of DoubleVerify; any person who is known to be the beneficial owner of more than five percent of the Shares; any immediate family member of any of the foregoing persons, including 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 of the director, executive officer, nominee or more than five percent beneficial owner, and any person (other than a tenant or employee) sharing the household of such director, executive officer, nominee or more than five percent beneficial owner; and any firm, corporation or other entity in which any of the foregoing persons is a general partner or, for other ownership interests, a limited partner or other owner in which such person has a beneficial ownership interest of ten percent or more.

#### Relationship with Providence
Stockholder's Agreement

In connection with our IPO, we entered into the Stockholder's Agreement with the Providence Investor. The Stockholder's Agreement governs the relationship between Providence and us, including matters related to our corporate governance, such as Board nomination rights and information rights. The Stockholder's Agreement grants Providence the right to designate for nomination for election a number of Providence Designees equal to at least 5% of the total number of directors comprising the Board at such time as long as Providence owns at least 5% but less than 20% of the outstanding Shares. For purposes of calculating the number of Providence Designees that Providence is entitled to nominate, any fractional amounts will be rounded to the nearest whole number (but not below one so long as Providence owns at least 5% of the outstanding Shares) and the calculation will be made on a pro forma basis after taking into account any increase in the size of the Board.

Pre-IPO Stockholders Agreement

Prior to our IPO, we were party to an amended and restated stockholders agreement, dated as of November 18, 2020, with the Providence Investor and certain other existing stockholders of the Company (the "Pre-IPO Stockholders Agreement"). The Pre-IPO Stockholders Agreement contained restrictions on the ability of the parties thereto to freely transfer Shares and an agreement to vote their Shares on certain matters presented to the stockholders, including in favor of all directors nominated by the Board for election. The Providence Investor was entitled under the Pre-IPO Stockholders Agreement to nominate for election, fill vacancies and appoint at least six of the then eight members of the Board, as well as certain

other rights. The Pre-IPO Stockholders Agreement granted the parties thereto piggyback registration rights in connection with a registered offering of Shares in which the Providence Investor participated (including the IPO). The Pre-IPO Stockholders Agreement automatically terminated on the date the SEC declared effective the IPO registration statement and was replaced by the Stockholder's Agreement.

Registration Rights Agreement

In connection with our IPO, we entered into a registration rights agreement with the Providence Investor and certain of our other existing stockholders (the "Registration Rights Agreement"). The Registration Rights Agreement grants to Providence and its permitted assigns, customary demand registration rights and piggyback registration rights, and to such other existing stockholders and their permitted assigns, customary piggyback registration rights, in each case subject to customary terms and conditions.

#### Relationships with Directors and Executive Officers
Director Indemnification Agreements

We have entered into an indemnification agreement with each of our directors. The indemnification agreements provide our directors with contractual rights to the indemnification and expense advancement rights provided under our Bylaws, as well as contractual rights to additional indemnification as provided in the indemnification agreements.

Registration Rights Agreement

In connection with our IPO, we entered into the Registration Rights Agreement. Mark Zagorski, Nicola Allais, Andrew Grimmig and the Laura B. Desmond Revocable Trust (for which Laura B. Desmond is trustee) are parties to the Registration Rights Agreement. Each of Mr. Zagorski, Mr. Allais, Mr. Grimmig and Ms. Desmond is a director and/or executive officer of the Company. See "—Relationship with Providence—Registration Rights Agreement."

#### Your Vote is Important
The Board requests that you submit a proxy to vote your Shares as soon as possible. Your voting instructions are confidential and will not be disclosed to persons other than those recording the vote, except if you make a written comment on the proxy card, otherwise communicate your vote to management or authorize such disclosure.

#### Quorum Requirement
Presence in person or by proxy of the holders of a majority of the total voting power of all outstanding Shares entitled to vote at the Annual Meeting constitutes a quorum for the transaction of business at the Annual Meeting. Shares for which valid proxies are delivered or that are held by a stockholder that attends the Annual Meeting in person will be considered part of the quorum. Once a Share is represented for any purpose at the meeting, it is deemed present for quorum purposes for the remainder of the meeting and for any adjourned meeting. Shares represented by proxies at the Annual Meeting, including "broker non-votes" (explained below) and those that are marked "WITHHOLD" or "ABSTAIN", will be counted as shares present and entitled to vote for purposes of establishing a quorum.

#### Voting Your Shares
Holders of Record

---

If you wish to return your proxy card by mail, mail to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.

These instructions appear on your Notice or proxy card. If you submit a proxy on the Internet or by telephone, please have your Notice or proxy card available for reference when you do so. If you submit a proxy via the Internet or by telephone, please do not mail in your proxy card.

For holders of record, proxies submitted by mail, on the Internet or by telephone will be voted by the individuals named on the proxy card in the manner you indicate. If you execute, date and deliver a proxy card but do not specify how your Shares are to be voted, the proxies will vote as recommended by the Board on all matters on the agenda for the Annual Meeting (see "Proposals for Your Vote") and will use their discretion with respect to any other matters properly presented for a vote at the Annual Meeting or any postponement or adjournment thereof.

Holders in Street Name

If your Shares are held in an account at a brokerage firm, bank, broker-dealer or other similar organization, then you are a holder of Shares in "street name". The organization holding your account will have

74 The Annual Meeting, Voting and Other Information 2026 PROXY STATEMENT

------

[**TABLE OF CONTENTS**](#TOC2)

provided you with proxy materials. As the beneficial owner, you have the right to direct the organization how to vote the Shares held in your account. If you want to vote in person at the Annual Meeting, you must obtain a legal proxy from your broker, bank or other intermediary and present it at the meeting, and submit it with your vote.

If you are a holder of Shares in street name and you do not submit voting instructions to your broker, bank or other intermediary, the intermediary generally may vote your Shares in its discretion only on routine matters. Intermediaries do not have discretion to vote their clients' Shares on non-routine matters in the absence of voting instructions from the beneficial stockholder. A broker non-vote occurs when a broker or nominee holding shares for a beneficial owner votes on one proposal, but does not vote on another proposal because the broker or nominee does not have discretionary voting power and has not received instructions from the beneficial owner.

At the Annual Meeting, only Proposal 3 (ratification of appointment of the independent auditor) is considered routine and may be voted upon by the intermediary if you do not submit voting instructions. As a result, if your Shares are held in street name and you do not give your bank or broker instructions on how to vote on Proposal 3, your Shares will be voted by the broker in its discretion. All other proposals on the Agenda for the Annual Meeting are non-routine matters, and intermediaries may not use their discretion to vote on these proposals in the absence of voting instructions from you. Your broker will therefore not have discretion to vote on the "non-routine" matters set forth in Proposal 1 or Proposal 2 absent direction from you. Broker non-votes will not have an effect on the outcome of Proposal 1 or Proposal 2.

#### Changing Your Vote or Revoking Your Proxy
If you are a holder of record and wish to revoke your proxy instructions, you must either (1) subsequently submit a proxy via the Internet or by telephone, which will be available until 11:59 p.m., Eastern Time, May 20, 2026; (2) sign, date and deliver a later-dated proxy card so that it is received before the Annual Meeting; (3) submit a written revocation; or (4) send a notice of revocation via the Internet at www.proxyvote.com. If you hold your Shares in street name, you must follow the instructions of your broker, bank or other intermediary to revoke your voting instructions.

#### Vote Required for Each Proposal

#### Proposal 1—Election of Directors
**Board Recommendation:** FOR each of the Company's nominees.

**Vote Required:** Affirmative vote of at least a plurality in voting power of the Shares outstanding present in person or represented by proxy at the Annual Meeting and entitled to vote on the subject matter. In accordance with our Bylaws, stockholders do not have the right to cumulate their votes for the election of directors.

**Effect of Abstentions:** No effect.

**Effect of Broker Non-Votes:** No effect.

#### Proposal 2—Advisory Vote on the Compensation of our Named Executive Officers
**Board Recommendation:** FOR

**Vote Required:** Affirmative vote of a majority in voting power of the Shares outstanding present in person or represented by proxy at the Annual Meeting and entitled to vote on the subject matter.

**Effect of Abstentions:** Same effect as a vote AGAINST the proposal.

**Effect of Broker Non-Votes:** No effect.

Because this proposal is an advisory vote, the result will not be binding on our Board or Company. Our Board and Compensation Committee will consider the outcome of the vote when determining the compensation of our NEOs.

#### Proposal 3—Ratification of Appointment of Independent Registered Public Accounting Firm
**Board Recommendation:** FOR

**Vote Required:** Affirmative vote of a majority in voting power of the Shares outstanding present in person or represented by proxy at the Annual Meeting and entitled to vote on the subject matter.

**Effect of Abstentions:** Same effect as a vote AGAINST the proposal.

**Effect of Broker Non-Votes:** There will be no broker non-votes associated with this proposal, as the ratification of our independent registered public accounting firm is a routine matter. As a result, if your Shares are held in "street name" and you do not give your bank or broker instructions on how to vote, your Shares will be voted by the broker in its discretion.

#### Matters to be Presented
We are not aware of any matters to be presented at the Annual Meeting other than those described in this Proxy Statement. If any matters not described in this Proxy Statement are properly presented at the meeting, unless otherwise provided, the proxies will use their own judgment to vote your Shares. If the meeting is adjourned or postponed, the proxies can vote your Shares at the adjournment or postponement as well.

We are using "notice and access" procedures to distribute our proxy materials to our stockholders. This method reduces the amount of paper used in producing proxy materials and lowers the costs associated with mailing the proxy materials to stockholders. We are mailing a Notice of Internet Availability of Proxy Materials to stockholders. The Notice includes instructions on how to access the materials over the Internet and how to request a paper or e-mail copy. The Notice further provides instructions on how stockholders may elect to receive proxy materials in the future in printed form or by electronic mail. To select a method of delivery while voting is open, holders of record may follow the instructions when voting online at www.proxyvote.com. At any time, you may also choose your method of delivery of the Company's proxy materials by visiting www.proxyvote.com. If you own Shares indirectly through a broker, bank or other intermediary, please contact the intermediary for additional information regarding delivery options.

Holders of record will have the Notice or proxy materials delivered directly to your mailing address or electronically if you have previously consented to that delivery method.

Holders of Shares in street name will have the proxy materials or the Notice forwarded to you by the intermediary that holds the Shares.

Eliminating Duplicative Proxy Materials

Some brokers or other nominee record holders may only deliver one set of proxy materials to multiple stockholders who share an address (known as "householding"). All stockholders sharing an address will receive in a single envelope a single Proxy Statement and the Annual Report, along with individual proxy cards or individual Notices for each stockholder. If you are a stockholder who shares an address and last name with one or more other stockholders and would like to revoke your householding consent or you are a stockholder eligible for householding and would like to participate in householding, please contact Equiniti Trust Company, LLC by mail at Operations Center, 48 Wall Street, Floor 23, New York NY 10005 or by telephone at 1-800-937-5449. You will be removed from the householding program within 30 days of receipt of the revocation of your consent. Additional copies of our proxy materials are available upon request by contacting: Equiniti Trust Company, LLC by mail at Operations Center, 48 Wall Street, Floor 23, New York NY 10005 or by telephone at 1-800-937-5449.
