COMMON STOCK PURCHASE AGREEMENT

THIS COMMON STOCK PURCHASE AGREEMENT (this “Agreement”) is made as of April 9, 2021, by and between DoubleVerify Holdings, Inc., a Delaware corporation (the “Company”), and Tiger Global Investments, L.P. (the “Investor”).

THE PARTIES HEREBY AGREE AS FOLLOWS:

1. Purchase and Sale of Stock.

1.1 Sale and Issuance of Common Stock.

(a) Subject to the terms and conditions of this Agreement, the Investor agrees to purchase from the Company, and the Company agrees to sell and issue to the Investor, the Shares (as defined below) at a price per share equal to the per share initial public offering price (before underwriting discounts and expenses) in the Qualified IPO (as defined below) (the “IPO Price”). “Shares” shall mean the number of shares of Common Stock of the Company (the “Common Stock”), equal to $30 million divided by the IPO Price, rounded down to the nearest whole share (with the total purchase price correspondingly reduced for such fractional share amount). “Qualified IPO” shall mean the issuance and sale of shares of Common Stock by the Company or the sale of shares of Common Stock by certain existing stockholders of the Company (collectively, the “Selling Stockholders”), pursuant to an Underwriting Agreement to be entered into by and among the Company, the Selling Stockholders and certain underwriters (the “Underwriters”), in connection with the Company’s initial public offering pursuant to the Company’s Registration Statement on Form S-1 (File No. 333-254380) (the “Registration Statement”) and/or any related registration statements (the “Underwriting Agreement”).

(b) All references to numbers of shares and prices per share in this Agreement shall be appropriately adjusted to reflect any stock dividend, stock split, reverse stock split, combination or other recapitalization or reclassification of shares by the Company occurring after the date of this Agreement and prior to the determination of the IPO Price.

1.2 Closing. The purchase and sale of the Shares shall take place remotely via the exchange of documents and signature pages at the time immediately subsequent to the closing of the Qualified IPO (which time and place are designated as the “Closing”), subject to the satisfaction or waiver of all the conditions set forth in Sections 4 and 5 hereof. At the Closing, the Investor shall make payment of the purchase price for the Shares by wire transfer in immediately available funds to the account specified by the Company against delivery to the Investor of the Shares registered in the name of the Investor, which Shares shall be uncertificated shares.

1.3 Registrable Equity Securities. For the avoidance of doubt, the Company and the Investor hereby agree that the Shares shall be considered Registrable Equity Securities (as such term is defined in that certain Amended and Restated Stockholders Agreement, dated as of November 18, 2020, by and among the Company, the Investor and the other parties thereto

(the “Stockholders Agreement”)) for any purpose under the Stockholders Agreement or a successor agreement providing for registration rights.

2. Representations, Warranties and Covenants of the Company. The Company hereby represents and warrants to the Investor that as of the date hereof and as of the date of the Closing:

2.1 Organization, Good Standing and Qualification.

(a) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as now conducted.

(b) The Company is duly qualified to transact business and is in good standing in each jurisdiction in which it is required to be so qualified or in good standing, except where the failure to so qualify or be in good standing would not be material and adverse to the Company.

2.2 Authorization. All corporate action on the part of the Company, its officers, directors and stockholders necessary for the authorization, execution and delivery of this Agreement, the performance of all obligations of the Company under this Agreement, and the authorization, issuance, sale and delivery of the Shares being sold hereunder has been taken, and this Agreement constitutes a valid and legally binding obligation of the Company, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of general application affecting enforcement of creditors’ rights generally, and (b) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies.

2.3 Valid Issuance of Common Stock. The Shares being purchased by the Investor hereunder, when issued, sold and delivered in accordance with the terms of this Agreement for the consideration expressed herein, will be duly and validly issued, fully paid and nonassessable and will be free of liens, encumbrances and restrictions on transfer other than restrictions on transfer under applicable state and federal securities laws or as contemplated hereby. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority on the part of the Company is required in connection with the consummation of the transactions contemplated by this Agreement, except (a) a filing, if any, required pursuant to Regulation D promulgated by the United States Securities and Exchange Commission (the “SEC”) under the Securities Act (as defined below), (b) the filings required by applicable state “blue sky” securities laws, rules and regulations or (c) such other post-closing filings as may be required.

or contract to which it is a party or by which it is bound, or, to its knowledge, of any provision of any federal or state statute, rule or regulation applicable to the Company. The execution, delivery and performance of this Agreement, and the consummation of the transactions contemplated by this Agreement, will not result in any material violation or default or be in conflict with or constitute, with or without the passage of time and giving of notice, either a material default under any such provision, instrument, judgment, order, writ, decree or contract or an event that results in the creation of any material lien, charge or encumbrance upon any assets of the Company or the suspension, revocation, impairment, forfeiture, or nonrenewal of any material permit, license, authorization, or approval applicable to the Company, its business or operations or any of its assets or properties.

2.7 Brokers or Finders. The Company has not engaged any brokers, finders or agents such that the Investor will incur, directly or indirectly, as a result of any action taken by the Company, any liability for brokerage or finders’ fees or agents’ commissions, or any similar charges in connection with the sale of the Shares contemplated by this Agreement.

2.8 Private Placement. Assuming the accuracy of the representations, warranties and covenants of the Investor set forth in Section 3 of this Agreement, no registration under the Securities Act is required for the offer and sale of the Shares by the Company to the Investor under this Agreement, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would require such a registration.

3. Representations, Warranties and Covenants of the Investor. The Investor hereby represents and warrants that, as of the date hereof and as of the date of the Closing:

3.1 Organization, Good Standing and Qualification. The Investor is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization (to the extent the concept of good standing is applicable in the relevant jurisdiction).

3.2 Authorization. The Investor has full power and authority to enter into this Agreement, and this Agreement constitutes a valid and legally binding obligation of the Investor, enforceable in accordance with its terms except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

3.3 Purchase Entirely for Own Account. By the Investor’s execution of this Agreement, the Investor hereby confirms, that the Shares to be received by the Investor will be acquired for investment for the Investor’s own account, not as a nominee or agent, and not with a view to the distribution of any part thereof, and that the Investor has no present intention of selling, granting any participation in, or otherwise distributing the same, except as permitted by applicable federal or state securities laws. By executing this Agreement, the Investor further represents that the Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Shares.

3.4 Disclosure of Information. The Investor believes it has received all the information it considers necessary or appropriate for deciding whether to purchase the Shares. The Investor further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares and the business, properties, prospects and financial condition of the Company. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 of this Agreement or the right of the Investor to rely thereon.

3.5 Investment Experience. The Investor is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the

Shares. The Investor also represents that it has not been organized for the purpose of acquiring the Shares.

3.10 Legends. The Investor understands that the Shares may bear one or all of the following legends:

(a) “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF ANY OTHER JURISDICTIONS. THESE SECURITIES MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS (PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM). INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.”

(b) “THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO A RESTRICTION ON TRANSFER AS SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. AS A RESULT OF SUCH AGREEMENT, THESE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF PRIOR TO 180 DAYS AFTER THE EFFECTIVE DATE OF A REGISTRATION STATEMENT FILED BY THE COMPANY FOR ITS INITIAL PUBLIC OFFERING OF THE COMMON STOCK OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES OF THESE SHARES.”

3.11 Market Stand-Off Agreement; Lock-Up Agreement. The Investor hereby agrees that it shall not, to the extent requested by the Company and the Underwriters, sell or otherwise transfer or dispose of the Shares, other than to donees, partners or Affiliates (as defined below) of the Investor who agree to be similarly bound, for up to 180 days following the effective date of the Qualified IPO (the “Lock-Up Period”).

In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the book-entry accounts representing the Shares and to impose stop transfer instructions with respect to the Shares until the end of such period. The provisions of this Section 3.11 shall not apply to shares acquired in market purchases following the Qualified IPO. In addition, the Investor hereby confirms that it has executed and delivered to the Underwriters a lock-up agreement in the form attached hereto as Exhibit A (the “Lock-Up Agreement”). The Lock-Up Agreement has been in full force and effect since the first public filing of the registration statement related to the Qualified IPO. For purposes of this Agreement, the term “Affiliates” means any individual or entity that directly or indirectly controls, is controlled by, or is under common control with the individual or entity in question.

3.12 Removal of Restrictive Legends. Following the expiration of the Lock-Up Period, in the event that the Shares become registered under the Securities Act or are eligible to be transferred without restriction in accordance with Rule 144 under the Securities Act, the Company shall (x) instruct the Company’s transfer agent to issue new uncertificated (book-entry) instruments representing the Shares, which shall not contain such portion of the above legend that is no longer applicable, (y) take all actions with the Company’s transfer agent reasonably requested by the Investor to permit such un-legended Shares to be deposited into the account specified by the Investor to the Company in writing, and (z) instruct the Company’s transfer agent to cause such Shares to be assigned the same CUSIP as the shares of Common Stock that are then traded on the principal stock exchange on which the shares of Common Stock are then listed; provided that, (1) the Investor surrenders to the Company the previously issued uncertificated (book-entry) instruments representing the Shares and (2) the Investor delivers a customary representation letter to the extent requested by the Company’s transfer agent.

7.7 Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by facsimile or electronic mail or otherwise delivered by hand, messenger or courier service addressed:

Xxxxx (xxxxxxx@xxxxxxxxx.xxx).

Each such notice or other communication shall for all purposes of this Agreement be treated as effective or having been given (i) if delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one business day after deposit with the courier), or (ii) if sent via mail, at the earlier of its receipt or five days after the same has been deposited in a regularly-maintained receptacle for the deposit of the United States mail, addressed and mailed as aforesaid, or (iii) if sent via electronic mail, when directed to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day. In the event of any conflict between the Company’s books and records and this Agreement or any notice delivered hereunder, the Company’s books and records will control absent fraud or error.

7.8 Brokers or Finders. The Company shall indemnify and hold harmless the Investor from any liability for any commission or compensation in the nature of a brokerage or finder’s fee or agent’s commission (and the costs and expenses of defending against such liability or asserted liability) for which the Investor or any of its constituent partners, members, officers, directors, employees or representatives is responsible to the extent such liability is attributable to any inaccuracy or breach of the representations and warranties contained in Section 2.7, and the Investor agrees to indemnify and hold harmless the Company from any liability for any commission or compensation in the nature of a brokerage or finder’s fee or agent’s commission (and the costs and expenses of defending against such liability or asserted liability) for which the Company or any of its constituent partners, members, officers, directors, employees or representatives is responsible to the extent such liability is attributable to any inaccuracy or breach of the representations and warranties contained in Section 3.7.

7.10 Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Agreement, and such court will replace such illegal, void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision. The balance of this Agreement shall be enforceable in accordance with its terms.

7.11 Entire Agreement. This Agreement and the documents referred to herein constitute the entire agreement among the parties. No party shall be liable or bound to any other party in any manner with regard to the subjects hereof or thereof by any warranties, representations or covenants except as specifically set forth herein or therein.

7.12 Specific Performance. The parties to this Agreement hereby acknowledge and agree that the Company would be irreparably injured by a breach of this Agreement by the Investor, and the Investor would be irreparably injured by a breach of this Agreement by the Company, and that money damages are an inadequate remedy for an actual or threatened breach of this Agreement because of the difficulty of ascertaining the amount of damage that will be suffered by the aggrieved party in the event that this agreement is breached. Therefore, each of the parties to this Agreement agree to the granting of specific performance of this Agreement and injunctive or other equitable relief in favor of the aggrieved party as a remedy for any such breach, without proof of actual damages, and the parties to this Agreement further waive any requirement for the securing or posting of any bond in connection with any such remedy. Such remedy shall not be deemed to be the exclusive remedy for breach of this Agreement, but shall be in addition to all other remedies available at law or in equity to the aggrieved party. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this lock-up agreement (this “Lock-Up Agreement”) and continuing to and including the date 180 days after the date (the “Offering Date”) set forth on the final prospectus (the “Prospectus”) used to sell the Shares (the “Lock-Up Period”), the undersigned shall not, and shall not cause or direct any of its affiliates to, (i) offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to

receive shares of Common Stock of the Company (such options, warrants or other securities, collectively, “Derivative Instruments”), including without limitation any such shares or Derivative Instruments now owned or hereafter acquired by the undersigned, (ii) engage in any hedging or other transaction or arrangement (including, without limitation, any short sale or the purchase or sale of, or entry into, any put or call option, or combination thereof, forward, swap or any other derivative transaction or instrument, however described or defined) which is designed to or which reasonably could be expected to lead to or result in a sale, loan, pledge or other disposition (whether by the undersigned or someone other than the undersigned), or transfer of any of the economic consequences of ownership, in whole or in part, directly or indirectly, of any shares of Common Stock of the Company or Derivative Instruments, whether any such transaction or arrangement (or instrument provided for thereunder) would be settled by delivery of Common Stock or other securities, in cash or otherwise (any such sale, loan, pledge or other disposition, or transfer of economic consequences, a “Transfer”) or (iii) otherwise publicly announce any intention to engage in or cause any action or activity described in clause (i) above or transaction or arrangement described in clause (ii) above. The undersigned represents and warrants that the undersigned is not, and has not caused or directed any of its affiliates to be or become, currently a party to any agreement or arrangement that provides for, is designed to or which reasonably could be expected to lead to or result in any Transfer during the Lock-Up Period. For the avoidance of doubt, if the undersigned is an officer (as defined under the rules and regulations of the Financial Industry Regulatory Authority, Inc. (“FINRA”)) or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed or other Shares the undersigned may purchase in the Offering.
