Business and Basis of Presentation	Business and Basis of Presentation MNTN, Inc. (the “Company”) is a performance TV software company focused on providing performance advertising services through a unified online advertising platform that includes segmentation tools, intelligent campaign planning, advance audience targeting, prospecting, creative ad builder, and data analytics reporting. The Company, which was formed in 2009 as a Delaware corporation, is headquartered in Austin, Texas. On May 23, 2025, the Company closed its initial public offering ("IPO"), in which 8,400,000 shares of Class A common stock were issued and sold by the Company at $16.00 per share. On August 25, 2021, the Company completed the acquisition of Maximum Effort Marketing, LLC (“Maximum Effort Marketing”), a creative marketing agency primarily focused on the production of television ads. On December 30, 2021, the Company completed the acquisition of QuickFrame, Inc. (“QuickFrame”), a marketplace platform that uses a video-as-a-service solution to make video creation fast and affordable. On April 1, 2025 the Company divested its ownership in Maximum Effort Marketing and transferred its interest in Maximum Effort Marketing to an affiliate of its original owner (the “Maximum Effort Marketing Transaction”). As part of the divestiture, Maximum Effort Marketing has continued to provide creative services to the Company under a new arrangement. Unaudited Condensed Consolidated Financial Statements The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial statements and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto included for the year ended December 31, 2025, which can be found in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC (the “2025 Annual Report”). Use of Estimates The preparation of 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, including those related to the recognition and disclosure of contingent liabilities, the amounts in the provision for expected credit losses, assumptions used in the Black-Scholes model to determine the fair value of stock options and employee stock plan purchases, determination of useful lives of internal use software, valuation of intangible assets and goodwill, and valuation of and the realization of tax assets and estimates of tax liabilities. 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 result of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. The Company may engage third party valuation specialists to assist with estimates related to the valuation of its intangible assets and goodwill and contingent liabilities. Such estimates often require the selection of appropriate valuation methodologies and models, and significant judgment in evaluating ranges of assumptions and financial inputs. By their nature, estimates are subject to an inherent degree of uncertainty and actual results could differ from those estimates. Emerging Growth Company Status The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has not opted out of the extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates Recently Adopted Accounting Standards In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”), which provides a practical expedient for estimating expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under Topic 606, Revenue from Contracts with Customers. The Company has adopted ASU 2025-05 for these condensed consolidated financial statements for the three months ended March 31, 2026 on a prospective basis. The adoption had no material impact on the Company’s condensed consolidated financial statements and notes. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires greater disaggregation of information and consistent categories in the effective tax rate reconciliation and income taxes paid disaggregated by jurisdictions. It also includes certain other amendments to improve the effectiveness of income tax disclosures. For public entities, this guidance will be effective on a prospective basis, with an option to apply it retrospectively, for annual periods beginning after December 15, 2024. As an emerging growth company that has not opted out of the extended transition period for complying with new or revised financial accounting standards, the amendments in ASU No. 2023-09 are effective for annual periods beginning after December 15, 2025, with early adoption permitted. Accordingly, the Company will adopt ASU No. 2023-09 for its annual consolidated financial statements and notes for the year ending December 31, 2026. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and notes. In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires entities to disclose additional information about certain expense categories in the notes to the financial statements. This guidance may be applied retrospectively or prospectively for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and notes. In September 2025, the FASB issued ASU No. 2025-06, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which clarifies and modernizes the accounting for costs related to internal-use software. This guidance may be applied using a retrospective, prospective or modified transition approach for interim and annual periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and notes. In November 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, to add clarity and consistency for disclosure requirements in interim periods. The amendments can be applied on either a prospective or retrospective basis, and are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and notes. Significant Accounting Policies The Company's significant accounting policies are disclosed in its audited consolidated financial statements and related notes thereto included for the year ended December 31, 2025, which can be found in the 2025 Annual Report. Other than the following, there have been no changes to the Company's significant accounting policies during the three months ended March 31, 2026: Revenue Recognition The Company recognizes revenue in accordance with ASC 606. The Company generates revenue by charging its customers a variable usage-based fee based on the level of ad spend and through charging fees for various ad production activities. The Company also offers customers incentive programs where the customers can earn rebates or creative services based on achieving certain levels of ad spend during the contract term. The Company recognizes revenue through the following steps: –identification of the contract, or contracts, with a customer; –identification of the performance obligations in the contract; –determination of the transaction price; –allocation of the transaction price to the performance obligations in the contract; and –recognition of revenue when, or as, the performance obligations are satisfied. The determination as to whether revenue should be reported gross of amounts billed to customers (gross basis) or net of payments to suppliers (net basis) requires significant judgment and is based on its assessment of whether the Company is acting as the principal or an agent in the transaction. The Company has determined that it does not act as the principal in the purchase and sale of digital advertising inventory because it does not control the advertising inventory and it does not set the price which is the result of an auction within the marketplace. Based on these and other factors, the Company reports revenue from the sale of advertising inventory on its platform on a net basis. The Company has also determined that it does not act as the principal in its production activities because the Company’s role as a facilitator does not give the Company complete control over the specified good, is not primarily responsible for the performance of third-party services, cannot redirect those services to fulfill other contracts, does not carry inventory risk, and does not set the price of third party services used in the production activities. Therefore, the Company also reports revenue from its production activities on a net basis. The Company bills its customers on a gross basis, inclusive of the cost of procuring the advertising inventory. The Company reports revenue on a net basis which represents gross billings net of amounts it pays suppliers for the cost of advertising inventory and net of consideration it pays to certain advertising agencies that meet the definition of customers under ASC 606. The Company’s accounts receivable are recorded at the amount of gross billings to customers, net of allowance, for the amounts it is responsible to collect, and its accounts payable are recorded at the amounts payable to suppliers. Accordingly, both accounts receivable and accounts payable appear large in relation to revenue reported on a net basis. Sales and Marketing Sales and marketing expense consists of personnel-related costs (including salaries, commissions, bonuses, benefits and stock-based compensation), as well as costs related to promotional activities such as online advertising, branding products and trade shows, fees paid to third parties for marketing and product research, and commissions paid to certain advertising agencies. Commission costs are expensed as incurred.
