Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and include the operations of the Company, Viant Technology LLC and its wholly owned subsidiaries. Viant Technology LLC is considered a variable interest entity. The Company is the primary beneficiary and sole managing member of Viant Technology LLC and has decision-making authority that significantly affects the economic performance of the entity. As a result, the Company consolidates Viant Technology LLC. All intercompany balances and transactions have been eliminated in consolidation.

Management believes that the accompanying condensed consolidated financial statements reflect the adjustments necessary for the fair statement of its condensed consolidated financial statements included in this Quarterly Report on Form 10-Q. The condensed consolidated balance sheet as of December 31, 2025 was derived from the audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements. Certain information and disclosures normally included in the Company's consolidated financial statements prepared in accordance with GAAP have been omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and related notes included in its Annual Report on Form 10-K for the year ended December 31, 2025.

The condensed consolidated statement of operations for the three months ended March 31, 2026 is not necessarily indicative of the results to be expected for the year ending December 31, 2026, or for any other future annual or interim period.

There have been no material changes to the significant accounting policies as described in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Use of Estimates

The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, primarily those related to revenue recognition, stock-based compensation, income taxes, allowances for doubtful accounts, leases, the useful lives of capitalized software development costs and other property, equipment, and software and assumptions used in the impairment analyses of long-lived assets, investments and

goodwill. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amount of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The impact of widespread macroeconomic and geopolitical uncertainties, including the impact of bank failures, tariffs and international trade conflicts, high interest rates, inflationary pressures, labor shortages, shortages of goods and services, supply chain constraints, pandemics, political cycles, changes in laws and interpretations of laws, international conflicts and acts of terrorism on our business continues to evolve. Many of our estimates and assumptions consider these macroeconomic and geopolitical factors in the market, which require increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available on the potential impact on our business of global economic and business events, our estimates may change materially in future periods as a result.

Comprehensive Loss

For the periods presented, net loss is equal to comprehensive loss.

Segment Information

The Company has a single reportable operating segment which owns and operates a DSP that enables marketers and their advertising agencies to automate and centralize the planning, buying and measurement of their video, audio and display ads across most channels, including connected TV ("CTV"), streaming audio, digital out-of-home, mobile and desktop in the United States. The Company derives its revenues from the services it provides through utilization of its platform. In reaching this conclusion of a single reportable operating segment, management considers the definition of the chief operating decision maker (“CODM”), how the business is defined by the CODM, the nature of the information provided to the CODM and how that information is used to make operating decisions, allocate resources and assess performance.

The Company’s CODM is comprised of the chief executive officer and chief operating officer. The CODM uses multiple measures within the consolidated statements of operations, balance sheets, and cash flows and thus utilizes the entirety of those consolidated statements to make key resource decisions and assess performance at the consolidated level. The CODM does not review segment assets at a different asset level and category. The consolidated net income (loss) is the measure of segment net income (loss) that is most consistent with U.S. GAAP.

Cash and Cash Equivalents

For purposes of balance sheet presentation and reporting of cash flows, the Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents. Cash and cash equivalents are comprised of cash in bank accounts and money market funds for which the carrying value approximates fair value due to their short-term nature. Cash equivalents are valued based on Level 1 inputs which consist of quoted prices in active markets. As of March 31, 2026, cash equivalents included money market funds of $156.8 million.

Accounts Receivable, Net of Allowances

The following table presents changes in the allowance for doubtful accounts for the three months ended March 31, 2026:



Balance as of December 31, 2025	$	1,055
Provision for doubtful accounts	204
Write-offs, net of recoveries	(19)
Balance as of March, 31, 2026	$	1,240

Concentration of Risk

Financial instruments that potentially subject the Company to concentration of risk consist principally of cash and cash equivalents and accounts receivable. The Company maintains its cash with financial institutions and its cash levels exceed the Federal Deposit Insurance Corporation’s federally insured limits. Market conditions can impact the viability of these institutions. In the event of failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we will be able to access uninsured funds in a timely manner or at all. Accounts receivable include amounts due from customers with principal operations primarily in the United States.

Non-Marketable Equity Securities

We hold investments in non-marketable equity securities that represent investments in privately held companies without readily determinable fair values. The Company measures investments without readily determinable fair values at cost, less impairment, adjusted for observable price changes. These investments are included within other assets on our condensed consolidated balance sheets.

As of March 31, 2026, the Company had non-marketable equity investments without readily determinable fair value of $3.5 million. The Company did not record any adjustments to the carrying value resulting from observable price changes or impairment and accordingly did not recognize any gains or losses for the three months ended March 31, 2026.

JOBS Act Election as an Emerging Growth Company

On April 5, 2012, the Jumpstart Our Business Startups Act (the “JOBS Act”) was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies. As an “emerging growth company,” the Company may, under Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”), delay adoption of new or revised accounting standards applicable to public companies until such standards would otherwise apply to private companies. An “emerging growth company” is one with less than $1.235 billion in annual gross revenues, has issued $1 billion or less of non-convertible debt over a three-year period and is not deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission (“SEC”). The Company will remain an emerging growth company until December 31, 2026, or sooner if it no longer qualifies.

The Company has elected to take advantage of the benefits of this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the first to occur of the date that it (i) is no longer an “emerging growth company” or (ii) affirmatively and irrevocably opts out of this extended transition period provided by Securities Act Section 7(a)(2)(B).
