Financial outlook is based on information as of today, August 7, 2025, and may be impacted by factors outside IAS’s control. See “Forward Looking Statements.”

* See “Supplemental Disclosure Regarding Non-GAAP Financial Information” section herein for an explanation of these measures. IAS is unable to provide a reconciliation for forward-looking guidance of adjusted EBITDA to net income, the most closely comparable GAAP measure without unreasonable effort, because certain material reconciling items, such as depreciation and amortization, interest (income) expense, income taxes, and acquisition, restructuring 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 third quarter of 2025 in the range of $18.5 million to $19.5 million and for the full year 2025 in the range of $71.0 million to $73.0 million.

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 before depreciation and amortization, stock-based compensation, interest (income) expense, income taxes, acquisition, restructuring and integration costs, foreign exchange (gain) loss, net, asset impairments, 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, as discussed below, 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.

Reconciliations of historical adjusted EBITDA to its most directly comparable GAAP financial measure, net income/loss, 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.

Forward-Looking Statements
This earnings press release contains forward-looking statements that are subject to risks and uncertainties. All statements other than statements of historical fact included in this press release are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance, including guidance, and business, including pipeline and industry trends. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “plan,” “intend,” “believe,” “may,” “will,” “should,” “can have,” “likely,” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events. For example, all statements we make relating to our estimated and projected costs, profitability, expenditures, cash flows, growth rates and financial results or our plans and objectives for future operations, growth initiatives or strategies 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) the adverse effect on our business, operating results, financial condition, and prospects from various macroeconomic factors, including instability in geopolitical or market conditions; (ii) our failure to innovate or make the right investment decisions; (iii) our ability to provide digital or cross-platform analytics; (iv) our failure to maintain or achieve industry accreditation standards; (v) our dependence on integrations with advertising platforms, demand side providers (“DSPs”) and proprietary platforms that we do not control; (vi) our ability to compete successfully with our current or future competitors in an intensely competitive market, including with respect to the Oracle opportunity; (vii) our inability to use software licensed from third parties; (viii) our international expansion; (ix) our ability to expand into new channels; (x) our ability to sustain our profitability and revenue growth rate; (xi) risks that our customers do not pay or choose to dispute their invoices; (xii) risks of material changes to revenue share agreements with certain DSPs; (xiii) our dependence on the overall demand for advertising; (xiv) our ability to effectively manage our growth; (xv) 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; (xvi) our ability to successfully execute our international plans; (xvii) the risks associated with the seasonality of our market; (xviii) our ability to maintain high impression volumes; (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) public health outbreaks, epidemics, pandemics, or other public health crises; (xxxiv) risks posed by earthquakes, fires, floods, and other natural catastrophic events; (xxxv) the risk that a perceived failure to comply with laws and industry self-regulation may damage our reputation; and (xxxvi) 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.
