Viant Technology Announces First

Quarter 2026 Financial Results

Acquired TVision Insights, a leader in attention measurement across linear TV and CTV

Achieved record first quarter results across all key metrics, including a 25% increase in revenue

Generated record first quarter CTV advertiser spend(1), accounting for over 50% of total ad spend

IRVINE, Calif., May 11, 2026 – Viant Technology Inc. (Nasdaq: DSP), a leader in AI-powered programmatic advertising, today reported financial results for its first quarter ended March 31, 2026.

"Viant delivered record first quarter results, exceeding the high end of our guidance range across both the top and bottom lines for the quarter," said Tim Vanderhook, Co-Founder and CEO, Viant. "Our continued success is amplified by our recent landmark acquisition of TVision, which further transforms Viant from a media execution platform into a highly differentiated advertising intelligence company, equipped with proprietary data, measurement, and activation capabilities that enables advertisers to drive optimal media decisions. By integrating TVision's measurement and proprietary attention data into our AI-powered ad platform, we have created a first-of-its-kind solution that transforms viewer attention into real-time actionable signals for planning, bidding, and optimized decisioning. Our exclusive data now spans content, identity and attention, strategically positioning Viant as the most sophisticated and effective platform delivering outcomes for advertisers. With the addition of TVision, we expect to accelerate top-line growth, improve profitability and seize market share."

Recent Business Highlights:

•Acquired TVision Insights, establishing Viant as an objective measurement and buying platform uniquely capable of valuing inventory across linear TV, CTV, Netflix, YouTube and Prime Video, which uniquely enables Viant to direct advertiser spend to destinations projected to maximize human engagement and deliver optimal outcomes.

•Launched inaugural performance advertising campaigns within Outcomes, the first fully autonomous advertising solution built for the open-internet. Outcomes leverages Viant's newly developed AI Lattice Brain, a decisioning

architecture purpose-built to plan and execute campaigns autonomously by continuously evaluating proprietary data signals including Viant's Household ID, IRIS_ID, TVision attention insights, supply quality scoring models, historical campaign performance data and more.

•CTV spend reached a seasonal record high in the first quarter, representing over 50% of total advertiser spend on the platform.

"We are off to a strong start to the year, delivering contribution ex-TAC growth of 18%, exceeding the mid-point of our guidance, and adjusted EBITDA growth of 81%, exceeding the high end of our guidance," stated Larry Madden, CFO of Viant. "On May 1st, we closed on our acquisition of TVision, enabling the exclusive integration of proprietary attention insights directly into our AI-powered ad platform. TVision materially strengthens our targeting and measurement capabilities, which we expect will drive increased ad spend across our platform, elevate our take-rate and lead to adjusted EBITDA margin expansion over time. Reflecting strengthening advertiser demand, continued adoption of ViantAI, incremental use of our proprietary data, and increased engagement across our sales pipeline - we expect to accelerate top-line growth in each quarter throughout 2026, while delivering Adjusted EBITDA margin expansion for the year."

For the second quarter 2026, the Company expects:

•Revenue in the range of $98.5 million to $101.5 million

•Contribution ex-TAC in the range of $58.5 million to $60.5 million

•Non-GAAP operating expenses in the range of $45.5 million to $46.5 million

•Adjusted EBITDA in the range of $13.0 million to $14.0 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 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.

Non-GAAP Financial Measures

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 cost per mille 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, net, less TAC, stock-based compensation, depreciation, amortization, and certain other items that are not related to our core operations, such as acquisition and restructuring costs. 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 acquisition and restructuring costs as well as Tax Receivable Agreement (the "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 acquisition and restructuring costs as well as TRA remeasurement expense and 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 acquisition and restructuring costs as well as TRA remeasurement expense and 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"), performance stock units ("PSUs"), and nonqualified stock options ("NQSOs") are considered potentially dilutive shares of Class A common stock.

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.
