Debt Disclosure [Abstract]

Long-term debt

On September 29, 2021, the Company entered into a credit agreement with various lenders, which was amended on June 23, 2023 (as amended, the "Credit Agreement”). The Credit Agreement provides for an initial $300,000 in commitments for revolving credit loans (the “Revolver”), which amount may be increased or decreased under specific circumstances, with a $30,000 letter of credit sublimit and a $100,000 alternative currency sublimit. In addition, the Credit Agreement provides for the ability to request incremental term loan facilities, in a minimum amount of $5,000 for each facility. Borrowings pursuant to the Credit Agreement may be used for working capital and other general corporate purposes, including for acquisitions permitted under the Credit Agreement. During the three months ended March 31, 2024, the Company had no draw downs and paid down $30,000 on the Revolver.

Borrowings under the Credit Agreement are scheduled to mature on September 29, 2026. The Credit Agreement contains certain customary events of default including failure to make payments when due thereunder, and failure to observe or perform certain covenants. In connection with the entry into the Revolver, the Company incurred costs of $2,318 that are included in Long-term debt, net, in the Condensed Consolidated Balance Sheets.

The June 23, 2023, amendment changed the market interest rate on outstanding borrowings from LIBOR to SOFR. The amendment became effective at the end of the applicable interest period for any LIBOR borrowings outstanding on the amendment effective date, which was June 30, 2023. The interest rates for the Revolver under the Credit Agreement (i) for U.S. dollar loans are equal to the applicable rate for base rate loans range from 0.75% to 1.50% per annum, (ii) for Term SOFR Loans (as defined in the Credit Agreement) ranging from 1.75% to 2.50% per annum, (iii) for RFR Loans (as defined in the Credit Agreement) denominated in sterling range from 1.7826% to 2.5326%, and (iv) for RFR Loans denominated in euro range from 1.7965% to 2.5456%, in each case, based on the Senior Secured Net Leverage Ratio (as defined in the Credit Agreement). Base rate borrowings may only be made in dollars. The Company is required to pay a commitment fee during the term of the Credit Agreement ranging from 0.20% to 0.35% per annum of the average daily undrawn portion of the revolving commitments based on the Senior Secured Net Leverage Ratio. The interest rate on March 31, 2024 was 7.4%.

Any borrowings under the Credit Agreement may be repaid, in whole or in part, at any time and from time to time without premium or penalty other than customary breakage costs, and any amounts repaid may be reborrowed. No mandatory prepayments will be required other than when borrowings and letter of credit usage exceed the aggregate commitment of all lenders.

The Credit Agreement contains covenants requiring certain financial information to be submitted quarterly and annually. In addition, the Company is also required to comply with certain financial covenants such as maintaining a Total Net Leverage Ratio (as defined in the Credit Agreement) of 3.50 to 1.00 or lower and maintaining a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of 2.50 to 1.00. As of March 31, 2024, the Company was in compliance with all covenants contained in the Credit Agreement.

Income Tax Disclosure [Abstract]
Income taxes	Income taxes At the end of each interim period, the Company estimates the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or unrecognized tax benefits is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences, and the likelihood of the realization of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or the Company’s tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision in the quarter in which the change occurs. For the three months ended March 31, 2024, the Company recorded an income tax benefit of $134 and for the three months ended March 31, 2023, the Company recorded an income tax provision of $3,026. The Company’s effective tax rate for the three months ended March 31, 2024 and 2023 was 9.6% and 49.0%, respectively. The Company's effective tax rate for the three months ended March 31, 2024 is lower than for the respective three months ended March 31, 2023, primarily due to non-deductible stock-based compensation and other permanent tax differences and discrete items. The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. The Company is not currently under audit in any taxing jurisdiction.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

The carrying value of cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximated fair value due to their short maturities.

Financial instruments

Financial instruments are valued based on observable inputs and classified within Level 2 of the fair value hierarchy. The carrying value of long-term debt approximates its fair value based on Level 2 inputs as the principal amounts outstanding are subject to variable interest rates that are based on market rates (see Note 8).

Accounting Policies [Abstract]

Basis of presentation and summary of significant accounting policies

This summary of significant accounting policies is presented to assist in understanding the Company’s condensed consolidated financial statements. These accounting policies have been consistently applied in the preparation of the condensed consolidated financial statements.

(a) Basis of presentation

The Company’s condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and reflect the financial position, results of operations and cash flows for all periods presented. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP.

The accompanying interim Condensed Consolidated Balance Sheets as of March 31, 2024, the Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income, of Cash Flows and of Changes in Stockholders’ Equity for the three months ended March 31, 2024 and 2023, and the related footnote disclosures are unaudited. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and, in management’s opinion, include all adjustments necessary to state fairly the consolidated financial position of the Company. All adjustments made were of a normal recurring nature. The results for the three months ended March 31, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024, or for any future period.

The Company’s significant accounting policies are discussed in Note 2 to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“SEC”) on February 27, 2024 (the "2023 Form 10-K") and these unaudited condensed consolidated financial statements should be read in conjunction with the 2023 Form 10-K.

During Q1, 2024, the Company identified an immaterial error in its previously issued unaudited condensed consolidated financial statements for the three months ended March 31, 2023, six months ended June 30, 2023 and nine months ended September 30, 2023. Specifically, lease liabilities arising from right of use assets within the non-cash investing and financing supplemental disclosure included all leases rather than leases arising during the noted period. We have revised the March 31, 2023 disclosure from $28.1 million to $0 to reflect the activity during that period. We will revise the six months ended June 30, 2023 disclosure from $30.4 million to $3.9 million and the nine months ended September 30, 2023 disclosure from $29.3 million to $4.9 million in our Form 10-Qs for the quarters ended June 30, 2024 and September 30, 2024, respectively, to be filed later this year. These revisions did not impact any other amounts presented in the condensed consolidated financial statements.

(b) Basis of consolidation

The condensed consolidated financial statements include the accounts of Integral Ad Science Holding Corp. and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include fair value of assets acquired in business combinations, including assumptions with respect to future cash inflows and outflows, discount rates, assets useful lives, market multiples, the allocation of purchase price consideration in the business combination valuation of acquired assets and liabilities, the estimated useful lives of intangible assets and internal use software, the allowance for credit losses, goodwill impairment testing, assumptions used to calculate equity-based compensation, and the realization of deferred tax assets. The Company bases its estimates on past experience, market conditions, and other assumptions that the Company believes are reasonable under the circumstances, and the Company evaluates these estimates on an ongoing basis. Actual results may differ from these estimates due to risks and uncertainties, including the continued uncertainty surrounding rapidly changing market and economic conditions due to high inflation, changes to fiscal and monetary policy, high interest rates, currency fluctuations, instability in the financial markets and disruptions in European economies as a result of the war in Ukraine and other geopolitical issues.

(d) Foreign currency

The reporting currency of the Company is the U.S. dollar. The functional currency of our foreign subsidiaries is the currency of the primary economic environment in which they operate, which is their local currency. The financial statements of these subsidiaries are translated into U.S. dollars using month-end rates of exchange for assets and liabilities, and average rates of exchange for revenue, costs and expenses. Translation gains and losses are recorded in accumulated other comprehensive loss in stockholders’ equity. Transaction gains and losses including those on intercompany transactions denominated in a currency other than the functional currency of the entity involved are included in foreign exchange loss, net in the Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income.

For the three months ended March 31, 2024, foreign exchange loss, net consists of unrealized foreign exchange losses of $1,395 and realized transaction losses of $174. For the three months ended March 31, 2023, foreign exchange gain, net consists of unrealized foreign exchange gains of $678 and realized transaction losses of $162.

(e) Cash, cash equivalents, and restricted cash

Cash equivalents include money market accounts and other highly liquid investments with an original maturity date of three months or less at the time of purchase. Cash amounts with restrictions are classified as restricted cash within the Condensed Consolidated Balance Sheets.

The company generated interest income of $954 and $528 during the three months ended March 31, 2024 and 2023, respectively.


	March 31, 2024		December 31, 2023
Cash and cash equivalents	$	83,947	$	124,759
Short term restricted cash	298		54
Long term restricted cash (held in other long-term assets)	2,482		2,477
Total cash, cash equivalents, and restricted cash shown in the Condensed Consolidated Statements of Cash Flows	$	86,727	$	127,290

(f) Accounts receivable, net

Accounts receivable are carried at the original invoiced amount less an allowance for credit losses. The allowance is estimated by pooling accounts receivables based on similar risk characteristics, and expected credit loss exposure is evaluated for each accounts receivable pool. Invoices are typically issued with net 30-days to net 90-days terms. Account balances are considered delinquent if payment is not received by the due date, and the receivables are written off when deemed uncollectible. These costs are recorded in general and administrative expenses within the Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income.

The activity in our allowance for credit losses consists of the following as of:


	March 31, 2024		March 31, 2023
Balance, beginning of period	$	8,645	$	6,691
(Decrease) increase in bad debt provision	(188)		514
Receivables written off and impact of exchange rates	(106)		26
Adoption of ASC 326	—		(1,271)
Balance, end of period	$	8,351	$	5,960

(g) Stock-based compensation

Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense over the requisite service period, which is generally the vesting period. The Company accounts for forfeitures as they occur. The Company used the following assumptions in valuing its market stock units ("MSUs"), shares granted under the Company's 2021 Employee Stock Purchase Program ("ESPP"), time-based service options, which vest over a period of time subject to continued employment ("Time-Based Options"), and return target options ("Return-Target Options"), which vest upon a realized cash return of the equity investment of funds affiliated with Vista Equity Partners ("Vista"), the Company’s largest shareholder.

Expected term — For time-based awards, the estimated expected term of options granted is generally calculated as the vesting period plus the midpoint of the remaining contractual term, as the Company does not have sufficient historical information to develop reasonable expectations surrounding future exercise patterns and post-vesting employment termination behavior. For awards subject to market and performance conditions, the expected term represents the period of time that the options granted are expected to be outstanding.

Expected volatility — Volatility is estimated based upon observed option-implied volatilities for the Company in addition to a group of peer companies. The Company believes this is the best estimate of the expected volatility over the weighted-average expected term of its option grants.

Risk-free interest rate — The risk-free interest rate is based on the implied yield currently available on U.S. Treasury instruments with terms approximately equal to the expected term of the option.

Expected dividend — The expected dividend assumption was based on the Company’s history and expectation of dividend payouts. The Company currently has no history or expectation of paying cash dividends on its common stock.

Fair value — Following the pricing of the Initial Public Offering, the Company’s shares have traded publicly, and accordingly the Company uses the applicable closing price of its common stock to determine fair value.

The Company used the following assumptions in valuing its stock-based compensation:


	March 31, 2024	March 31, 2023
Estimated fair value	$4.47	$3.35
Expected volatility (%)	50%	60%
Expected term (in years)	0.50	0.50
Risk-free interest rate (%)	5.15%	4.79%
Dividend yield	—	—

(h) Accounting pronouncements not yet adopted

On November 27, 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures," which requires incremental disclosures related to an entity's reportable segments. This ASU is effective for annual periods beginning after December 15, 2023. The Company does not expect the adoption of ASU 2023-07 to have a material impact on its consolidated financial statements.

On December 14, 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires companies to disclose more detailed information in their reconciliation of their statutory tax rate to their effective tax rate. The ASU also requires entities to disclosure more detailed information about income taxes paid, including by jurisdiction, pretax income (or loss) from continuing operations and income tax expense (or benefit). This ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2024. The Company is currently evaluating the impact of the adoption of ASU No. 2023-09 on its consolidated financial statements.

On March 6, 2024, the Securities and Exchange Commission issued a final rule that requires registrants provide climate-related disclosures in their annual reports on Form 10-K beginning with annual reports for the year ending December 31, 2024. The new rule requires additional disclosures both in the financial statements as well as other sections of the 10-K. The Company is currently evaluating the impact of the rule on its consolidated financial statements.

Integral Ad Science Holding Corp. Amended and Restated 2018 Non-Qualified Stock Option Plan

On August 1, 2018, the Company adopted the 2018 Non-Qualified Stock Option Plan (“2018 Plan”). Under the 2018 Plan, the Company issued (i) Time-Based Options that vest over four years with 25% vesting after twelve months and an additional 6.25% vesting at the end of each successive quarter thereafter; and (ii) Return-Target Options that were to vest upon the first to occur of sale of the Company, or, sale or transfer to any third party of shares, as a result of which, any person or

group other than Vista, obtains possession of voting power to elect a majority of the Board or any other governing body and the achievement of a total equity return multiple of 3.0 or greater.

The 2018 Plan contained a provision wherein, the Time-Based Options could be repurchased by the Company at cost upon resignation of the employee. Due to this repurchase feature, the Time-Based Options did not provide the employee with the potential benefits associated with a stock award holder, and therefore, these awards were not accounted for as a stock-based award under ASC 718, Compensation - Stock Compensation but instead, compensation cost was recognized when the benefit to the employee was determined to be probable.

The Return-Target Options were considered to contain both market (total stockholder return threshold) and performance (exit event) conditions. As such, the award was measured on the date of grant. Since the conditions for vesting related to the Return-Target Options were not met prior to the IPO, no stock-based compensation was recognized in the pre-IPO financial statements of the Company.

In connection with the IPO, the 2018 Plan was amended and restated (the “Amended and Restated 2018 Plan”) with the following modifications: (i) the provision to repurchase the Time-Based Options at cost upon resignation of the employee was removed and (ii) the Return-Target Options were modified to include vesting upon a sale of shares by Vista following the IPO resulting in Vista realizing a cash return on its investment in the Company equaling or exceeding $1.17 billion.

As a result of the modification to the Time-Based Options, the awards became subject to the guidance in ASC 718, Compensation - Stock Compensation. As the return multiple and vesting conditions associated with the Return-Target Options were also modified, the Company fair valued the Return-Target Options using a Monte Carlo simulation model. The Return-Target Options become exercisable following both (i) a registration of shares of common stock held by Vista and (ii) Vista realizing a cash return on its investment in the Company equaling or exceeding $1.17 billion.

Vesting of the Time-Based Options accelerates when the Return-Target Options vest and therefore, recognition of the remaining unamortized stock compensation expense related to the Time-Based Options will accelerate when the Return-Target Options vest.

The total number of Time-Based Options and Return Target Options outstanding under the Amended and Restated 2018 Plan as of March 31, 2024 were 2,251,431 and 1,342,092, respectively. The Company does not expect to issue any additional awards under the Amended and Restated 2018 Plan.

2021 Omnibus Incentive Plan (“2021 Plan”)

On June 29, 2021, the Company adopted the 2021 Plan to incentivize executive officers, management, employees, consultants and directors of the Company and to align the interests of the participants with those of the Company’s shareholders. As of March 31, 2024, there were 43,059,189 shares reserved for issuance under the 2021 Plan. The total number of shares reserved for issuance under the 2021 Plan is increased on January 1 of each of the first 10 calendar years during the term of the 2021 Plan, by the lesser of (i) 5% of the total number of shares of common stock outstanding on each December 31st immediately prior to the date of increase or (ii) such number of shares of common stock determined by our Board or compensation committee.

As of March 31, 2024, there were 1,147,846 total options outstanding under the 2021 Plan, consisting of 764,908 Time-Based Options and 382,938 Return-Target Options. The vesting conditions for the options issued under the 2021 Plan are identical to those described under the Amended and Restated 2018 Plan.

Stock option activity for the three months ended March 31, 2024 is as follows:

Restricted Stock Units ("RSUs")

RSUs under the 2021 Plan granted prior to May 2022 vest 25% each year and become fully vested after four years of service. RSUs under the 2021 Plan granted during or after May 2022 vest 6.25% at the end of each successive quarter and become fully vested after four years of service.

RSU activity for the three months ended March 31, 2024 is as follows:

Market Stock Units ("MSUs")

The Company granted MSUs under the 2021 Plan to certain executive officers. MSUs vest over four years, 25% on the first anniversary of the vesting commencement date and 6.25% at the end of each quarter thereafter. The number of MSUs eligible to vest is based on the performance of the Company's common stock over each applicable vesting period. The number of shares eligible to vest is calculated based on a payout factor. The payout factor is calculated by dividing (i) the average closing price of the Company's stock during the ten trading days immediately preceding the applicable vesting date by (ii) the closing price of the Company's stock on the vesting commencement date. The payout factor is zero if such quotient is less than 0.60 and is capped at 2.25. Such quotient is then multiplied by the target number of MSUs granted to the relevant officer to determine the number of shares to be issued to the officer at vesting. The grant date fair value of the MSUs was determined using a Monte-Carlo simulation. The Company uses the accelerated attribution method to account for these awards.

MSU activity for the three months ended March 31, 2024 is as follows:


	MSUs

2021 Employee Stock Purchase Plan

The Company adopted the ESPP for the primary purpose of incentivizing employees in future periods. As of March 31, 2024, 6,161,033 shares of common stock are reserved for issuance under the ESPP. The number of shares available for issuance under the ESPP is increased on January 1st of each calendar year, ending in and including 2031, by an amount equal to the lesser of (i) 1% of the shares outstanding on the final day of the immediately preceding calendar year and (ii) such smaller number 1of shares as is determined by our Board, subject to a maximum of 16,000,000 shares of our common stock for the portion of the ESPP intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. All Company employees and employees of designated subsidiaries are eligible to participate in the ESPP and may purchase shares through payroll deductions of up to 15% of their eligible compensation, subject to a maximum of $25 in any annual period for the portion of the ESPP intended to qualify as an employee purchase plan under Section 423 of the Internal Revenue Code.

The ESPP provides eligible employees the opportunity to purchase shares of the Company's common stock through payroll deductions at a price equal to 85% of the fair market value of the shares on (i) the first business day of the offering period or (ii) the last business day of the offering period, whichever is lower. The ESPP is offered to employees in six-month windows, with phases beginning on February 1 and August 1 of each calendar year. For the window that ended on January 31, 2023, employees purchased 111,163 shares at a price of $7.93 per share. For the window that ended on January 31, 2024, employees purchased 153,239 shares at a price of $12.37 per share. As of March 31, 2024, 5,734,225 shares were available for future purchase under the ESPP.
