Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Description of Business ON24, Inc. and its subsidiaries (together, ON24 or the Company) provides a leading, cloud-based intelligent engagement platform that combines best-in-class experiences with personalization and content, to enable sales and marketing organizations to capture and act on connected insights at scale. The Company’s platform offers a portfolio of interactive and hyper-personalized digital experience products that creates and captures actionable, real-time data at scale from millions of professionals to provide businesses with buying signals and behavioral insights to efficiently convert prospects into customers. The Company was incorporated in the state of Delaware in January 1998 as NewsDirect, Inc. and in December 1998 changed its name to ON24, Inc. The Company is headquartered in San Francisco, California. Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of ON24, Inc. and its wholly owned subsidiaries and have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial reporting. Certain information and note disclosures included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2024. In the opinion of management, the condensed consolidated financial statements reflect all adjustments that are normal and recurring in nature and necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Such estimates and assumptions include, but are not limited to, the determination of standalone selling price for the Company’s performance obligations, the expected benefit period for deferred contract acquisition costs, the allowance for doubtful accounts and billing reserves, the useful lives of long-lived assets and the assumptions used to measure stock-based compensation. Actual results could differ materially from these estimates. Significant Accounting Policies The Company’s significant accounting policies are disclosed in its annual report on Form 10-K for the year ended December 31, 2024. There have been no significant changes to these policies during the three months ended March 31, 2025. Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board (“FASB”) issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, as amended, which requires additional disclosures of specific expense categories included within each expense caption presented on the statements of operations. This ASU is effective with the Company’s 2027 annual reporting period and can be applied on a prospective or fully retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of this new standard on its financial statement disclosures. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands income tax disclosure to require consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid. This ASU is effective with the Company’s 2026 reporting period, with early application permitted. The Company is currently assessing the impact of the requirements and does not expect the adoption of this ASU to have a material impact on its consolidated financial statements and disclosures.
