Item 1.01. Entry Into a Material Definitive Agreement.

On June 17, 2025, Integral Ad Science Inc. (the “Borrower”) and Kavacha Holdings, Inc., as a guarantor, each a wholly owned domestic subsidiary of Integral Ad Science Holding Corp. (the “Company”), entered into a second amendment (the “Credit Agreement Amendment”) to the Borrower’s credit agreement, dated as of September 29, 2021 (as amended, restated, amended and restated, supplemented or otherwise modified, the “Credit Agreement”), with PNC Bank, National Association, as administrative agent, the other loan parties party thereto, the lenders party thereto and each other party thereto. The Credit Agreement governs the issuance of revolving credit loans (the “Revolving Credit Facility”) and term loan facilities.

The Credit Agreement Amendment, among other things, (i) extends the maturity date to June 17, 2030, (ii) adds a $30 million sub-facility for swingline loans and (iii) amends the Credit Agreement’s existing pricing margin to the Secured Overnight Financing Rate plus 1.50%, with three 0.25% step-ups based on the Company’s reported total net leverage ratio. Additionally, the Borrower is permitted, under certain circumstances, to increase the Revolving Credit Facility by at least $250 million.

The remaining terms of the Credit Agreement, as amended by the Credit Agreement Amendment, are substantially the same as the terms under the existing Credit Agreement, including with respect to financial covenants, events of default and loan acceleration.

The foregoing description of the Credit Agreement Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement Amendment, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
