 EXPLANATORY NOTE
 This Amendment No. 1 on Form 10-K/A (this "Amendment") amends the Annual Report on Form 10-K for Viant Technology Inc. ("Company") for the year ended December 31, 2024 filed with the Securities and Exchange Commission on March 3, 2025 (the "Original Filing"). This Amendment is being filed to revise Part II, Item 9A. "Controls and Procedures" ("Item 9A") by adding a sentence disclosing management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2024, which was inadvertently omitted from Item 9A in the Original Filing due to a typographical error.
 In accordance with Rule 12b-15 of the Securities and Exchange Act of 1934, as amended (the "Exchange Act"), this Amendment amends and restates Item 9A of the Original Filing in its entirety. In addition, as required by Rule 12b-15, new certifications by the Company's principal executive officer and principal financial officer are filed as exhibits to this Amendment.
 Except as described above or as otherwise expressly provided by the terms of this Amendment, no other changes have been made to the Original Filing. Except as otherwise indicated herein, this Amendment continues to speak as of the date of the Original Filing, and the Company has not updated the disclosures contained therein to reflect any events that occurred subsequent to the date of the Original Filing. Accordingly, this Amendment should be read together with the Original Filing.

 Item 9A. Controls and Procedures.
 Evaluation of Disclosure Controls and Procedures
 Our management, with the participation of our chief executive officer and chief financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Annual Report. Based on such evaluation, our chief executive officer and chief financial officer have concluded that as of December 31, 2024, our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.
 Management's Report on Internal Control Over Financial Reporting
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). We maintain internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP.
 Internal control over financial reporting includes maintaining records that, in reasonable detail, accurately and fairly reflect our transactions and dispositions of assets; providing reasonable assurance that transactions are recorded as necessary for the preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America; providing reasonable assurance that receipts and expenditures of Company assets are made in accordance with authorizations of management and our board of directors; and providing reasonable assurance that unauthorized acquisition, use or disposition of Company assets that could have a material effect on the consolidated financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our consolidated financial statements would be prevented or detected.
 Under the supervision and with the participation of our chief executive officer and chief financial officer, our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria set forth in "Internal Control—Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this assessment, our management concluded that our internal control over financial reporting was effective as of December 31, 2024.
 We have excluded from the scope of our assessment of internal control over financial reporting the operations and related assets of IRIS.TV, which we acquired on November 6, 2024. These exclusions are consistent with the SEC Staff guidance that an assessment of a recently acquired business may be omitted from the scope of our assessment of the effectiveness of disclosure controls and procedures that are also part of internal control over financial reporting in the twelve months following the acquisition. The total assets and total net revenues of IRIS.TV represent 1% and <1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2024.
 Attestation Report of the Independent Registered Public Accounting Firm
 This Annual Report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting due to an exemption established by the JOBS Act for "emerging growth companies".
 Changes in Internal Control over Financial Reporting
 As a result of the IRIS.TV acquisition, we have implemented new processes and controls over accounting for an acquisition, including determining the fair value of the assets acquired and liabilities assumed.
 Except as disclosed above, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(d) and 15d-15(d) under the Exchange Act) during the three months ended December 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
 Limitations on the Effectiveness of Disclosure Controls and Procedures
 Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and implemented, can provide only reasonable, not absolute, assurance that the control system's objectives will be met.

 Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues within a company are detected. The inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.
