Item 1.01.

Entry into a Material Definitive Agreement.

Merger Agreement

As previously reported, on September 24, 2025, Integral Ad Science Holding Corp., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Igloo Group Parent, Inc., a Delaware corporation (“Parent”), and Igloo Group Acquisition Company, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”). Parent and Merger Sub are affiliates of investment funds managed by Novacap Management Inc. (“Novacap”). Pursuant to the Merger Agreement, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving as a wholly owned subsidiary of Parent (the “Surviving Corporation”).

The board of directors of the Company (the “Company Board”) has unanimously (i) determined that it is fair to, and in the best interests of the Company and its stockholders, and declared it advisable, to enter into the Merger Agreement providing for the Merger, in accordance with the General Corporation Law of the State of Delaware (the “DGCL”); (ii) approved and declared advisable the Merger Agreement, the execution and delivery of the Merger Agreement by the Company, the performance by the Company of its covenants and other obligations thereunder, and the consummation of the Merger upon the terms and conditions set forth therein; (iii) resolved to recommend that the Company’s stockholders adopt the Merger Agreement and the Merger in accordance with the DGCL; and (iv) directed that the Merger Agreement be submitted to the Company’s stockholders for adoption.

Effect on Capital Stock

Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.001 per share, of the Company (“Company Common Stock”) that is issued and outstanding as of immediately prior to the Effective Time (other than any shares of Company Common Stock held by the Company as treasury stock, held by any subsidiary of the Company or owned by Parent or any of its subsidiaries (including Merger Sub), or any shares of Company Common Stock as to which appraisal rights have been properly exercised in accordance with Delaware law) will be automatically cancelled, extinguished and converted into the right to receive cash in an amount equal to $10.30, without interest thereon (the “Per Share Price”).

Representations and Warranties; Covenants

The Company, Parent and Merger Sub have each made customary representations, warranties and covenants in the Merger Agreement. Among other things, the Company has agreed, subject to certain exceptions, from the date of the Merger Agreement until the earlier to occur of the termination of the Merger Agreement pursuant to Article VIII of the Merger Agreement and the Effective Time, (i) to use commercially reasonable efforts to conduct its business in all material respects in the ordinary course of business, (ii) not to take certain actions prior to the Effective Time without the prior written consent of the other party (not to be unreasonably withheld, conditioned or delayed) and (iii) not to solicit or engage in discussions or negotiations with respect to any alternative business combination transaction.

Treatment of Company Equity Awards

At the Effective Time, each outstanding option to purchase shares of Company Common Stock (“Company Option”), other than Company Options that have an exercise price per share of Company Common Stock as of immediately prior to the Effective Time that is greater than or equal to the Per Share Price (the “Underwater Options”), will automatically be cancelled and converted into the right to receive an amount in cash, without interest and subject to applicable withholding taxes, equal to the product of (i) the total number of shares of Company Common Stock subject to such Company Option as of immediately prior to the Effective Time and (ii) the excess, if any, of the Per Share Price over the exercise price per share of Company Common Stock of such Company Option.

At the Effective Time, each Underwater Option will be cancelled for no consideration.


Each award of restricted stock units of the Company (each, a “Company RSU”) that is outstanding and vested as of immediately prior to the Effective Time, or that vests in accordance with its terms as a result of the consummation of the transactions contemplated by the Merger Agreement (“Vested Company RSUs”) will be cancelled and converted into the right to receive an amount in cash, without interest and subject to applicable withholding taxes, equal to the product of (i) the Per Share Price and (ii) the total number of shares of Company Common Stock subject to such Vested Company RSU as of immediately prior to the Effective Time.

Each Company RSU that is outstanding as of immediately prior to the Effective Time and that is not a Vested Company RSU (an “Unvested Company RSU”) will be cancelled and converted into a contingent right to receive an amount in cash (each, a “Converted Cash Award”) equal to the product of (i) the Per Share Price and (ii) the total number of shares of Company Common Stock subject to such Unvested Company RSU as of immediately prior to the Effective Time, which Converted Cash Award will continue to have, and will be subject to, the same and terms and conditions (including vesting conditions) as applied to the corresponding Unvested Company RSUs immediately prior to the Effective Time, except (A) for terms rendered inoperative by reason of the consummation of the transactions contemplated by the Merger Agreement and other administrative or ministerial changes determined by Parent and (B) that the surviving corporation will pay any portion of a converted cash award that vests to the applicable holder thereof, less any applicable withholding taxes, no later than the first regularly scheduled payroll date following the first day of the month following the date on which such portion vests.

With respect to all awards of market share units of the Company outstanding as of immediately prior to the Effective Time (collectively, the “Company MSUs”), 50% of such Company MSUs will, at the Effective Time, automatically be cancelled and converted into a Converted Cash Award equal to the product of (i) the Per Share Price and (ii) the total number of shares of Company Common Stock subject to such Company MSU as of immediately prior to the Effective Time (with the payout factor applicable to such Company MSU determined based on the Per Share Price), which Converted Cash Award will continue to have, and will be subject to, the same terms and conditions (including any service-based vesting conditions and double trigger vesting conditions, but excluding any performance-based vesting conditions) as applied to the corresponding Company MSUs immediately prior to the Effective Time, except (A) for terms rendered inoperative by reason of the consummation of the transactions contemplated by the Merger Agreement and other administrative or ministerial changes determined by Parent and (B) that the surviving corporation will pay any portion of a converted cash award that vests to the applicable holder thereof, less any applicable withholding taxes, no later than the first regularly scheduled payroll date following the first day of the month following the date on which such portion vests.

At the Effective Time, the remaining portion of Company MSUs outstanding as of immediately prior to the Effective Time will automatically be cancelled and converted into a restricted limited partnership unit award with respect to the common equity in an indirect parent entity of Parent that is the ultimate parent entity of Parent formed to effectuate the transactions contemplated by the Merger Agreement (the “Replacement Company MSU Award”), with the number of units covered by such Replacement Company MSU Award to be equal to the quotient of (i) the product of (x) the Per Share Price and (y) the total number of shares of Company Common Stock subject to such Company MSU as of immediately prior to the Effective Time (with the payout factor applicable to such Company MSU determined based on the Per Share Price), and (ii) the fair market value of such unit as of the Effective Time (based on the same price per unit paid to acquire equity in such entity in connection with the transactions contemplated by the Merger Agreement). The Replacement Company MSU Award will, subject to the holder’s continued service with Parent, the Surviving Corporation or one of its subsidiaries or a direct or indirect parent entity of Parent through the applicable vesting dates, vest and be settled at the same time the Company MSUs for which such Replacement Company MSU Award was exchanged would have vested and been settled pursuant to its terms. All Replacement Company MSU Awards will otherwise have the same terms and conditions (including service-based vesting conditions and double trigger vesting conditions, but excluding any performance-based vesting conditions) as applied to the Company MSUs for which they were exchanged, except for terms rendered inoperative by reason of the consummation of the transactions contemplated by the Merger Agreement and other administrative or ministerial changes determined by Parent; provided, however, that upon settlement of any Replacement Company MSU Award, the holder thereof will be permitted, in lieu of paying any taxes required to be withheld from such holder, to require Parent, the surviving corporation, or one of its subsidiaries or a direct or indirect parent entity of Parent, as applicable, to withhold a number of units otherwise issuable upon settlement having a fair market value equal to such required applicable withholding taxes.

Closing Conditions

The closing of the Merger is conditioned on certain conditions, including (i) the Company’s receipt of the written consent of the Company’s principal stockholders adopting the Merger Agreement (which consent was obtained on September 24, 2025) (the “Written Consent”), (ii) the expiration or termination of the waiting periods applicable to the transactions contemplated by the Merger Agreement under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and receipt of certain other regulatory approvals, (iii) an information statement (as contemplated by Regulation 14c-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) shall have been mailed to the Company’s stockholders at least 20 days prior to the closing date of the Merger, and (iv) other customary conditions for a transaction of this type, such as the absence of any legal restraint prohibiting the consummation of the transactions contemplated by the Merger Agreement, the accuracy of the Company’s representations and warranties contained in the Merger Agreement (except, generally, for any inaccuracies that have not had a Company Material Adverse Effect (as defined in the Merger Agreement)) and the absence of any Company Material Adverse Effect since the date of the Merger Agreement. The closing of the Merger will not occur prior to November 23, 2025 without the prior written consent of Parent.


Termination Rights

The Merger Agreement contains certain customary termination rights for the Company and Parent, including (i) if the Merger is not consummated on or before March 24, 2026 (the “Termination Date”), (ii) if the Written Consent was not obtained within 24 hours of execution of the Merger Agreement, (iii) if the other party breaches its representations, warranties or covenants in a manner that would cause the conditions to the closing of the transactions contemplated by the Merger Agreement to not be satisfied and fails to cure such breach within the applicable cure period, or (iv) if any law, order or judgment prohibiting the Merger has become final and non-appealable. In addition, (x) the Merger Agreement could have been terminated by the Company (A) prior to the receipt of the Written Consent (which consent was obtained on September 24, 2025), in order to enter into a definitive agreement providing for a superior proposal or (B) if, not sooner than November 23, 2025, all conditions to the Merger for three business days have been and continue to be satisfied (subject to customary exceptions) and Parent fails to consummate the Merger after receiving written notification from the Company, and (y) the Merger Agreement could have been terminated by Parent if, prior to the receipt of the Written Consent, the Company Board changed its recommendation.

Termination Fees

If (i) the Merger Agreement is validly terminated due to (x) the Written Consent not having been delivered (which consent was obtained on September 24, 2025), (y) the Company breaching its representations, warranties or covenants in a manner that causes the conditions to the closing of the transactions contemplated by the Merger Agreement to not be satisfied or (z) the Effective Time not having occurred by the Termination Date, (ii) prior to such termination, a third party publicly announced and did not withdraw a proposal for an alternative transaction for the Company, and (iii) within 12 months following such termination, the Company enters into a definitive agreement providing for an alternative control transaction and subsequently consummates such transaction, the Company will be required to pay Parent a termination fee equal to $52,500,000 (the “Company Termination Fee”). The Company is also required to pay the Company Termination Fee if (i) Parent terminates the Merger Agreement because the Company Board changes its recommendation regarding the Merger Agreement or (ii) if, prior to the receipt of the Written Consent (which consent was obtained on September 24, 2025) written consent of the Company’s stockholders, the Company terminated the Merger Agreement to enter into a definitive agreement providing for an alternative superior transaction.

Parent will be required to pay the Company a termination fee equal to $100,000,000 (the “Parent Termination Fee”) if (i) the Company terminates the Merger Agreement (x) due to Parent or Merger Sub breaching its representations, warranties or covenants that causes the conditions to the closing of the transactions contemplated by the Merger Agreement to not be satisfied, or (y) because all conditions to the Merger have been and continue to be satisfied (subject to customary exceptions) and Parent fails to consummate the Merger for three business days after receiving written notification from the Company or (ii) either the Company or Parent terminates the Merger Agreement because the Merger has not been consummated by the Termination Date and the Company would have been entitled to terminate the Merger Agreement due to Parent or Merger Sub breaching its representations, warranties or covenants that causes the conditions to the closing of the transactions contemplated by the Merger not to be satisfied or because Parent failed to consummate the Merger for three business days after receiving written notification from the Company all conditions to the Merger have been satisfied.
