•Viant has been designated as the Advertising Platform for Molson Coors, and will power their programmatic ad campaigns deployed across the open internet throughout the U.S. beginning in 2026.

•Winner of the "Best AI-Powered Advertising Solution" at the 8th annual MarTech Breakthrough Awards conducted by MarTech Breakthrough, a leading market intelligence organization that recognizes the most innovative companies in the global marketing, sales and advertising technology industry.

•Generated record Connected TV ("CTV") ad spend in the third quarter with CTV accounting for 46% of total ad spend on the platform.

•Generated record streaming audio ad spend in the third quarter, reflecting growing demand within a proliferating secular growth channel.

•Significantly expanded the reach of IRIS_ID, Viant's industry leading contextual identifier, through a new integration with leading CTV publisher, Tubi, enabling advanced contextual and emotional targeting and measurement capabilities for advertisers.

•Purchased 4.8 million shares of Class A common stock from May 1, 2024 through November 7, 2025 for a total of $59.6 million, including $37.9 million year-to-date through November 7, 2025.

"We are pleased to deliver third-quarter results that exceeded expectations," stated Larry Madden, CFO of Viant. "Contribution ex-TAC grew 12%, reaching the high-end of our guidance range. When excluding political spend and the impact of a seasonal advertiser transitioning off platform due to a recent corporate merger, revenue increased 19% and contribution ex-TAC increased 22%, reflecting strong underlying business performance. Our disciplined expense management also enabled us to increase adjusted EBITDA by nearly 10% in the quarter. Looking ahead to the fourth quarter, excluding these same headwinds, we expect revenue and contribution ex-TAC growth of 20% and 21%, respectively, at the midpoint of our guidance, underscoring continued momentum in our business. In addition, we expect to achieve an adjusted EBITDA margin of 37% as a percentage of contribution ex-TAC at the midpoint of our guidance, representing more than 500 basis points of improvement over the prior year period at the midpoint. We believe we are poised to meaningfully accelerate both top and bottom-line growth, attributable to a number of newly acquired brand and agency clients seeking to utilize our unique CTV product offering, industry-leading addressability solutions and ViantAI product suite."

•Revenue in the range of $101.5 million to $104.5 million

•Contribution ex-TAC in the range of $62.0 million to $64.0 million

•Non-GAAP operating expenses in the range of $39.5 million to $40.5 million

•Adjusted EBITDA in the range of $22.5 million to $23.5 million

Contribution ex-TAC, non-GAAP operating expenses, adjusted EBITDA, adjusted EBITDA as a percentage of contribution ex-TAC, non-GAAP net income, and non-GAAP earnings (loss) per share of Class A common stock—basic and diluted are non-GAAP financial measures. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with U.S. generally accepted accounting principles ("GAAP"). Reconciliations of these non-GAAP financial measures to Viant’s financial results as determined in accordance with GAAP are included at the end of this press release under “Reconciliation of Non-GAAP Financial Measures.” For a description of these non-GAAP financial measures, including the reasons management uses each measure, please see “Non-GAAP Financial Measures” in this press release. We are not able to estimate gross profit, total operating expenses or net income (loss) on a forward-looking basis or reconcile the guidance provided for contribution ex-TAC, non-GAAP operating expenses, or adjusted EBITDA to the closest corresponding GAAP financial measures on a forward-looking basis without unreasonable efforts due to the variability and complexity with respect to the charges excluded from these non-GAAP financial measures; in particular, the impact of future traffic acquisition costs and other platform operations expenses, as well as the measures and effects of our stock-based compensation related to equity grants that are directly impacted by unpredictable fluctuations in our share price and the potential forfeitures of equity grants. We expect the variability of the above charges could have a significant and potentially unpredictable impact on our future GAAP financial results.

(1)We define advertiser spend ("ad spend") as the total amount billed to our customers for activity on our platform inclusive of the costs of advertising media, third-party data, other add-on features and our platform fee we charge customers.

(2)For a discussion on how we define, use and calculate these non-GAAP financial measures and a reconciliation thereof to the most directly comparable GAAP financial measures, see “Non-GAAP Financial Measures” and the supplementary schedules under “Reconciliation of Non-GAAP Financial Measures” in this press release.

(1) Stock-based compensation and depreciation and amortization included in operating expenses are as follows (in thousands):

To provide investors and others with additional information regarding Viant’s results, we have included in this press release the following financial measures that are not calculated in accordance with GAAP: contribution ex-TAC, non-GAAP operating expenses, adjusted EBITDA, adjusted EBITDA as a percentage of contribution ex-TAC, non-GAAP net income (loss) and non-GAAP earnings (loss) per share of Class A common stock—basic and diluted. The Company’s management believes that this information can assist investors in evaluating the Company’s operational trends, financial performance, and cash generating capacity. Management believes these non-GAAP financial measures allow investors to evaluate the Company’s financial performance using some of the same measures as management.

Contribution ex-TAC is a non-GAAP financial measure. Gross profit is the most comparable GAAP financial measure, which is calculated as revenue less platform operations expense. In calculating contribution ex-TAC, we add back other platform operations expense to gross profit. Contribution ex-TAC is a key profitability measure used by our management and board of directors to understand and evaluate our operating performance and trends, develop short- and long-term operational plans and make strategic decisions regarding the allocation of capital. “Traffic acquisition costs” or “TAC” represents amounts incurred and payable to suppliers for the cost of advertising media, third-party data and other add-on features related to our fixed CPM pricing option and certain arrangements related to our percentage of spend pricing option. In particular, we believe that contribution ex-TAC can provide a measure of period-to-period comparisons for all pricing options within our business. Accordingly, we believe that this measure provides information to investors and the market in understanding and evaluating our operating results in the same manner as our management and board of directors.

Non-GAAP operating expenses is a non-GAAP financial measure. Total operating expenses is the most comparable GAAP financial measure. Non-GAAP operating expenses is defined by us as total operating expenses plus other expense (income), net, less TAC, stock-based compensation, depreciation, amortization, and certain other items that are not related to our core operations, such as restructuring and other charges, transaction expense, non-operational media purchases and Tax Receivable Agreement ("TRA") remeasurement expense. Non-GAAP operating expenses is a key component in calculating adjusted EBITDA, which is one of the measures we use to provide our business outlook to the investment community. Additionally, non-GAAP operating expenses is used by our management and board of directors to understand and evaluate our operating performance and trends, to prepare and approve our annual budget and to develop short- and long-term operational plans. We believe that the elimination of TAC, stock-based compensation, depreciation, amortization and certain other items not related to our core operations provides another measure for period-to-period comparisons of our business, provides additional insight into our core controllable costs, and is a useful metric for investors because it allows them to evaluate our operational performance in the same manner as our management and board of directors.

Adjusted EBITDA is a non-GAAP financial measure defined by us as net income (loss) before interest expense (income), net, income tax benefit (expense), depreciation, amortization, stock-based compensation and certain other items that are not related to our core operations, such as restructuring and other charges, transaction expense, non-operational media purchases and TRA remeasurement expense. Net income (loss) is the most comparable GAAP financial measure. Adjusted EBITDA as a percentage of contribution ex-TAC is a non-GAAP financial measure we calculate by dividing adjusted EBITDA by contribution ex-TAC for the period or periods presented. Net income (loss) as a percentage of gross profit is the most comparable GAAP financial measure.

Adjusted EBITDA and adjusted EBITDA as a percentage of contribution ex-TAC are used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short- and long-term operational plans. In particular, we believe that the exclusion of the amounts eliminated in calculating adjusted EBITDA can provide a measure for period-to-period comparisons of our business. Adjusted EBITDA as a percentage of contribution ex-TAC, a non-GAAP financial measure, is used by our management and board of directors to evaluate adjusted EBITDA relative to our profitability after costs that are directly variable to revenues, which comprise TAC. Accordingly, we believe that adjusted EBITDA and adjusted EBITDA as a percentage of contribution ex-TAC provide information to investors and the market in understanding and evaluating our operating results in the same manner as our management and board of directors.

Non-GAAP net income (loss) is a non-GAAP financial measure defined by us as net income (loss) adjusted to eliminate the impact of stock-based compensation and certain other items that are not related to our core operations, such as restructuring and other charges, transaction expense, non-operational media purchases and TRA remeasurement expense, as well as the income tax effect of these adjustments. Net income (loss) is the most comparable GAAP financial measure. Non-GAAP net income (loss) is a key measure used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of stock-based compensation and certain other items that are not related to our core

operations provides measures for period-to-period comparisons of our business and additional insight into our core controllable costs. Accordingly, we believe that non-GAAP net income (loss) provides information to investors and the market generally in understanding and evaluating our results of operations in the same manner as our management and board of directors.

Non-GAAP earnings (loss) per share of Class A common stock—basic and diluted is a non-GAAP financial measure defined by us as earnings (loss) per share of Class A common stock—basic and diluted, adjusted to eliminate the impact of stock-based compensation and certain other items that are not related to our core operations, such as restructuring and other charges, transaction expense, non-operational media purchases and TRA remeasurement expense, as well as the income tax effect of these adjustments. Earnings (loss) per share of Class A common stock—basic and diluted is the most comparable GAAP financial measure. Non-GAAP earnings (loss) per share of Class A common stock—basic and diluted is used by our management and board of directors to evaluate operating performance, generate future operating plans and make strategic decisions regarding the allocation of capital. In particular, we believe that the elimination of stock-based compensation and certain other items that are not related to our core operations provides measures for period-to-period comparisons of our business and provides additional insight into our core controllable costs. Accordingly, we believe that non-GAAP earnings (loss) per share of Class A common stock—basic and diluted provides information to investors and the market generally that aids in the understanding and evaluation of our results of operations in the same manner as our management and board of directors.

Basic non-GAAP earnings (loss) per share of Class A common stock is calculated by dividing the non-GAAP net income (loss) attributable to Class A common stockholders by the number of weighted-average shares of Class A common stock outstanding. Shares of our Class B common stock do not share in our earnings or losses and are therefore not participating securities. As such, separate presentation of basic and diluted non-GAAP earnings (loss) of Class B common stock under the two-class method has not been presented.

Diluted non-GAAP earnings (loss) per share of Class A common stock adjusts the basic non-GAAP earnings (loss) per share for the potential dilutive impact of shares of Class A common stock such as equity awards using the treasury-stock method and Class B common stock using the if-converted method. Diluted non-GAAP earnings (loss) per share of Class A common stock considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect. Shares of our Class B common stock, restricted stock units ("RSUs") and nonqualified stock options ("NQSOs") are considered potentially dilutive shares of Class A common stock. For the three and nine months ended September 30, 2025 and September 30, 2024, Class B common stock has been excluded from the computation of diluted earnings (loss) per share of Class A common stock because the effect would have been anti-dilutive under the if-converted method.

These non-GAAP financial measures should be considered in addition to, not as a substitute for or in isolation from, the Company’s financial information calculated in accordance with GAAP and should not be considered measures of the Company’s liquidity. Further, these non-GAAP financial measures as defined by the Company may not be comparable to similar non-GAAP financial measures presented by other companies, including peer companies, and therefore comparability may be limited. The presentation of such measures, which may include adjustments to exclude unusual or non-recurring items, should not be construed as an inference that the Company’s future results, cash flows or leverage will be unaffected by other unusual or non-recurring items. Management encourages investors and others to review Viant’s financial information in its entirety and not rely on a single financial measure.
