IAS now supports 9 additional content categories for a total of 45 and 6 additional languages for a total of 34.

•Quality Sync Pre-Bid Integrations – In February 2025, IAS announced the integration of Quality Sync pre-bid with Display and Video 360. In December 2024, IAS launched Quality Sync pre-bid in Amazon DSP. Quality Sync seamlessly syncs advertisers’ settings to streamline their efforts and drive superior results.

Financial Outlook

Utzschneider commented, “In addition to 14% revenue growth in the fourth quarter, we realized a 40% adjusted EBITDA margin for the period. In 2025, we expect to deliver profitable, double-digit revenue growth while maintaining a strong balance sheet and healthy cash flows to fuel investment in the business.”

IAS is introducing the following financial outlook for the first quarter and full year 2025:

First Quarter Ending March 31, 2025:

•Total revenue of $128 million to $131 million

•Adjusted EBITDA* of $38 million to $40 million

Year Ending December 31, 2025:

•Total revenue of $588 million to $600 million

•Adjusted EBITDA* of $202 million to $210 million

* See “Supplemental Disclosure Regarding Non-GAAP Financial Information” section herein for an explanation of Non-GAAP measures. IAS is unable to provide a reconciliation for forward-looking guidance of adjusted EBITDA to net income (loss), the most closely comparable GAAP measure, because certain material reconciling items, such as depreciation and amortization, interest expense, income tax expense (benefit), restructuring and severance costs, and acquisition and integration costs, cannot be estimated due to factors outside of IAS's control and could have a material impact on the reported results. However, IAS estimates stock-based compensation expense for the first quarter of 2025 in the range of $15 million to $17 million and for the full year 2025 in the range of $77 million to $81 million. A reconciliation is not available without unreasonable effort.

Supplemental Disclosure Regarding Non-GAAP Financial Information

We use supplemental measures of our performance, which are derived from our consolidated financial information, but which are not presented in our consolidated financial statements prepared in accordance with GAAP. Adjusted EBITDA is the primary financial performance measure used by management to evaluate our business and monitor ongoing results of operations. Adjusted EBITDA is defined as income/loss before depreciation and amortization, stock-based compensation, interest expense, income taxes, restructuring and severance costs, acquisition and integration costs, foreign exchange gains and losses, and other one-time, non-recurring costs. Adjusted EBITDA margin represents the adjusted EBITDA for the applicable period divided by the revenue for that period presented in accordance with GAAP.

We use non-GAAP financial measures to supplement financial information presented on a GAAP basis. We believe that excluding certain items from our GAAP results allows management to better understand our consolidated financial performance from period to period and better project our future consolidated financial performance as forecasts are developed at a level of detail different from that used to prepare GAAP-based financial measures. Moreover, we believe these non-GAAP financial measures provide our shareholders with useful information to help them evaluate our operating results by facilitating an enhanced understanding of our operating performance and enabling them to make more meaningful period-to-period comparisons. Although we believe these measures are useful to investors and analysts for the same reasons they are useful to management, these measures are not a substitute for, or superior to, U.S. GAAP financial measures or disclosures. Our non-GAAP financial measures may not be comparable to similarly titled measures of other companies. Other companies, including companies in our industry, may calculate non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

Reconciliation of historical adjusted EBITDA and corresponding margin to their most directly comparable GAAP financial measures, net income/loss and corresponding margin are presented below. We encourage you to review the reconciliations in conjunction with the presentation of the non-GAAP financial measures for each of the periods presented. In future fiscal periods, we may exclude such items and may incur income and expenses similar to these excluded items.

For example, all statements we make relating to our estimated and projected costs, expenditures, cash flows, growth rates and financial results or our plans and objectives for future operations, growth initiatives, strategies, client wins, or market penetration are forward-looking statements. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that we expected, including: (i) factors that affect the amount of advertising spending, such as economic downturns, instability in geopolitical or market conditions, and changes in tax treatment of advertising expenses; (ii) our failure to innovate or make the right investment decisions; (iii) our ability to provide digital or cross-platform analytics; (iv) our ability to sustain our profitability and revenue growth rate, particularly if our revenue growth continues to decline; (v) issues with the development and use of artificial intelligence and machine learning; (vi) our failure to maintain or achieve industry accreditation standards; (vii) our dependence on integrations with advertising platforms, demand side providers (“DSPs”), proprietary platforms, and ad servers that we do not control; (viii) our ability to maintain high impression volumes; (ix) our ability to compete successfully with our current or future competitors in an intensely competitive market; (x) our international expansion; (xi) our ability to expand into new channels; (xii) risks that our customers do not pay or choose to dispute their invoices; (xiii) risks of material changes to revenue share agreements with certain DSPs; (xiv) our dependence on the overall demand for advertising; (xv) our ability to effectively manage our growth; (xvi) the impact that any acquisitions we have completed in the past and may consummate in the future, strategic investments, or alliances may have on our business, financial condition, and results of operations; (xvii) our ability to successfully execute our international plans; (xviii) the risks associated with the seasonality of our market; (xix) the difficulty in evaluating our future prospects given our short operating history; (xx) uncertainty in how the market for buying digital advertising verification solutions will evolve; (xxi) interruption by man-made problems such as terrorism, computer viruses, or social disruptions; (xxii) the risk of failures in the systems and infrastructure supporting our solutions and operations; (xxiii) our ability to avoid operational, technical, and performance issues with our platform; (xxiv) risks associated with any unauthorized access to user, customer, or inventory and third-party provider data; (xxv) our ability to provide the non-proprietary technology, software, products, and services that we use; (xxvi) the risk that we are sued by third parties for alleged infringement, misappropriation, or other violation of their proprietary rights; (xxvii) our ability to obtain, maintain, protect, or enforce intellectual property and proprietary rights that are important to our business; (xxviii) our involvement in lawsuits to protect or enforce our intellectual

property; (xxix) risks that our employees, consultants, or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers; (xxx) risks that our trademarks and trade names are not adequately protected; (xxxi) the impact of unforeseen changes to privacy and data protection laws and regulation on digital advertising; (xxxii) our ability to maintain our corporate culture; (xxxiii) risks posed by earthquakes, fires, floods, public health crises, and other natural catastrophic events; (xxxiv) the risk that a perceived failure to comply with laws and industry self-regulation may damage our reputation; and (xxxv) other factors disclosed in our filings with the SEC. Given these factors, as well as other variables that may affect our operating results, you should not rely on forward-looking statements, assume that past financial performance will be a reliable indicator of future performance, or use historical trends to anticipate results or trends in future periods.

We derive many of our forward-looking statements from our operating budgets and forecasts, which are based on many detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. The forward-looking statements included in this press release are made only as of the date hereof. We undertake no obligation to update or revise any forward- looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
