IRVINE, Calif., March 10, 2022 (GLOBE NEWSWIRE) — Viant Technology Inc. (NASDAQ: DSP), a leading people-based advertising software company, today reported financial results for its fourth quarter and full year ended December 31, 2021.

“Our fourth quarter results, which beat our revenue and profitability guidance, concluded an incredible year for Viant. We greatly exceeded our expectations on all key financial metrics for the year and delivered against every aspect of our business strategy that we outlined in our February 2021 IPO, further proving out Viant’s business model and technology,” said Tim Vanderhook, co-founder and CEO of Viant. “We expect advertiser spend across our platform to further accelerate in 2022, and we are setting long term goals for revenue of at least $500 million and adjusted EBITDA as a percentage of contribution ex-TAC of at least 35% by 2025.”

Added co-founder and COO, Chris Vanderhook, “We made great strides in scaling our business in 2021. Marketer and agency clients are responding positively to the power and ease-of-use of our Adelphic omnichannel platform that leverages our household ID technology and new World Without Cookies (“WWC”) software to facilitate the buying and measurement of their digital advertising. Increased customer demand, the rapid development of our technology and the expansion and execution by our sales team, were key to driving our 2021 results, as evidenced by our growth in both the total number of and spend by active customers, as well as our continuing high customer retention rate.”

Looking forward, we expect advertiser spend across our platform to further accelerate in 2022, with growth of over 35% expected for the full year.”

  • Adjusted EBITDA in the range of $25.0 million to $35.0 million, reflecting continuing investments in Viant’s growth initiatives

Contribution ex-TAC, adjusted EBITDA, adjusted EBITDA as a percentage of contribution ex-TAC, non-GAAP net income (loss) and non-GAAP earnings (loss) per share—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 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 and net income (loss) on a forward-looking basis or reconcile the guidance provided for adjusted EBITDA and adjusted EBITDA as a percentage of contribution ex-TAC to the closest corresponding GAAP 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 measures; in particular, the measures and effects of our stock-based compensation related to new equity grants that are directly impacted by unpredictable fluctuations in our share price. We expect the variability of the above charges could have a significant and potentially unpredictable impact on our future GAAP financial results.

Conference Call and Webcast Details:
Viant will host a conference call and webcast to discuss its financial results on Thursday, March 10, 2022 at 2:00 p.m. Pacific Time (5:00 p.m. Eastern Time). A live webcast of the call can be accessed from Viant’s Investor Relations website. An archived version of the webcast will be available from the same website after the call.

(1) Prior to our IPO, which closed in February 2021, the Viant Technology LLC membership structure included certain convertible preferred units and common units. The number of Viant Technology LLC units prior to the IPO is significantly lower than the number of Viant Technology Inc Class A common shares due to restructuring of the entities in connection with the IPO, therefore contributing to a significantly lower earnings per share calculation in fiscal 2021 compared to fiscal 2020.

(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.

(3) We define advertiser spend across our platform as the total amount billed to our customers for activity on our platform, inclusive of advertising media, third-party data and other add-on features. See “Operational Metrics” for a discussion of how we use this metric and why it is useful to investors.

(4) We define an active customer as a customer that had total aggregate contribution ex-TAC of at least $5,000 through our platform during the previous twelve months. See “Operational Metrics” for a discussion of how we use this metric and why it is useful to investors.

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 U.S. generally accepted accounting principles (“GAAP”): contribution ex-TAC, adjusted EBITDA, adjusted EBITDA as a percentage of contribution ex-TAC, non-GAAP net income (loss) and non-GAAP earnings (loss) per share —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 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 measure, which is calculated as revenue less platform operations. 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” refers to amounts incurred and payable to suppliers for the cost of advertising media, third-party data and other add-on features.

Adjusted EBITDA is a non-GAAP financial measure. Net income (loss) is the most comparable GAAP financial measure. Adjusted EBITDA is defined by us as net income (loss) before interest expense, net, income tax expense (benefit), depreciation, amortization, stock-based compensation and certain other items that are not related to our core operations, such as restructuring charges, transaction expenses and the extinguishment of debt. Adjusted EBITDA as a percentage of contribution ex-TAC is a non-GAAP financial measure that 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 key measures 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 our non-GAAP measure, contribution ex-TAC, 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 traffic acquisition costs.

Non-GAAP net income (loss) is a non-GAAP financial measure. Net income (loss) is the most comparable GAAP measurement. Non-GAAP net income (loss) is 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 charges, transaction expenses and the extinguishment of debt. 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, gain on debt extinguishment, and certain other items that are not related to our core operations provides another measure for period-to-period comparisons of our business and provides additional insight into our core controllable costs.

Non-GAAP earnings (loss) per share of Class A common stock—basic and diluted is a non-GAAP financial measure. Earnings (loss) per share of Class A common stock—basic and diluted is the most comparable GAAP measure. Non-GAAP earnings (loss) per share of Class A common stock—basic and diluted is defined by us as earnings (loss) per share, adjusted to eliminate the impact of stock-based compensation and certain other items that are not related to our core operations, such as restructuring charges, transaction expenses, and the extinguishment of debt. Non-GAAP earnings (loss) per Class A common stock—basic and diluted 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, gain on extinguishment of debt and certain other items that are not related to our core operations provides another measure 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 Class A common stock—basic and diluted 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.

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 measures as defined by the Company may not be comparable to similar non-GAAP 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.
