Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation—The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial information. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, the unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes set forth in our final prospectus (the “IPO Prospectus”) filed with the SEC on June 4, 2026 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended, relating to our IPO Registration Statement. In the opinion of management, all adjustments, which include normal recurring adjustments necessary for a fair presentation, have been included. The results of operations for the periods presented are not necessarily indicative of the results to be expected for the full year or other periods. Certain amounts have been calculated using actual, non-rounded figures; accordingly certain amounts and percentages may not recalculate precisely.

Use of Estimates—The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates these estimates including, but not limited to, useful lives of long-lived assets, goodwill impairment, the allowance for sales rebates and incentives, deferred tax assets and liabilities and income taxes, capitalization of internal-use software, contingent consideration, redeemable convertible preferred stock, valuation of derivative instruments, valuation and recognition of stock-based compensation expense, and the estimate of the fair value of common stock prior to the IPO. These estimates are inherently subject to judgment and actual results could differ materially from those estimates.

Revenue Recognition—In accordance with ASC 606, Revenue from Contracts with Customers, revenue is recognized when control of the service is transferred to the customer. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to in exchange for these services.

To achieve the core principle of this standard, the Company determines revenue recognition by:

•Identification of a contract 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 Company generates revenue by facilitating advertiser’s purchase of ad inventory from publishers. The Company’s platform provides bidding and matching solutions that facilitate the placements of advertisers’ ads into publisher-owned ad inventory. The Company contracts with advertisers whose arrangements are governed by the Company’s terms and conditions, which generally stipulate payment terms of 30 days following the end of the month in which the services are invoiced. Substantially all of the Company’s contracts with customers have contractual terms of less than one year and are fully cancellable at any time or upon a short notice.

The Company’s performance obligation is to provide customers access to the platform to facilitate the advertiser’s purchase of ad inventory from publishers. The Company considers advertisers as customers. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as a principal or an agent in the transaction.

The Company does not control the ad inventory, because the Company does not have the substantive ability to direct the use of, nor obtain substantially all of the remaining benefits from, ad inventory. The Company also is not primarily responsible for fulfillment, as the publisher is ultimately responsible for the acceptability of the ad inventory. Accordingly, the Company has determined that it acts as an agent in the purchase and sale of digital ad inventory and reports revenue on a net basis.

The transaction price is comprised of variable consideration that is a factor of the number of completions of agreed upon actions, such as user installations and impressions, or advertisements displayed and the contractually agreed upon price per advertising unit with the customers, less consideration payable to publishers

or third parties providing access to publisher-owned ad inventory. The number of advertisements delivered and completions of agreed upon actions is determined at the end of each month, which resolves any uncertainty in the transaction price during the reporting period. The Company recognizes revenue at a point in time when the agreed upon action is completed or when the ad is displayed to a user. The Company also generates revenue from non-advertising offerings that is recognized ratably over the subscription period of generally up to twelve months. Revenue from non-advertising offerings was not material.

Contract assets consist of unbilled receivables that are recorded for contracts with performance obligations that have been satisfied but have not yet been billed. The current portion of contract assets is included in prepaid expenses and other current assets and the long-term portion is included in other assets on the condensed consolidated balance sheets. The Company had contract assets of $18.1 million and $18.5 million as of June 30, 2026, and December 31, 2025, respectively. Contract liabilities consist of deferred revenue and customer deposits. Deferred revenue is recorded when cash payments are received or due in advance of the Company’s satisfaction of its performance obligation. Customer deposits represent refundable amounts prepaid by customers which the Company does not extend credit to. The Company had deferred revenue of $1.4 million and $1.8 million as of June 30, 2026 and December 31, 2025, respectively, and customer deposits of $2.1 million and $2.2 million as of June 30, 2026 and December 31, 2025, respectively. Deferred revenue and customer deposits are included in other current liabilities on the condensed consolidated balance sheets. During the six months ended June 30, 2026 and 2025, the Company recognized $1.3 million and $1.5 million of revenue that was included in deferred revenue as of December 31, 2025 and 2024, respectively.

Substantially all of the Company’s unsatisfied performance obligations relate to contracts with an original expected length of one year or less.

The Company has elected the practical expedient to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the Company would otherwise have recognized is one year or less.

Disaggregation of Revenue

The following table presents revenue disaggregated by geography, based on billing location (in thousands):

Total	$	219,505	$	162,084	$	425,147	$	312,053

Redeemable Convertible Preferred Stock—Prior to the completion of its IPO, the Company’s Series A redeemable convertible preferred stock (“Redeemable Convertible Preferred Stock”) was classified as mezzanine equity in the condensed consolidated financial statements because it was redeemable upon the occurrence of certain deemed liquidation events that were not solely within the Company’s control. The Redeemable Convertible Preferred Stock was initially recognized at fair value upon issuance and was subsequently adjusted to its redemption value at each reporting date if it became currently redeemable or probable of becoming redeemable. In connection with the IPO, all outstanding shares of the Redeemable Convertible Preferred Stock automatically converted into 24,011,299 shares of the Company’s common stock, and the carrying amount of the Redeemable Convertible Preferred Stock was reclassified to permanent equity. As of June 30, 2026, no shares of Redeemable Convertible Preferred Stock were issued and outstanding. Refer to Note 7. Redeemable Convertible Preferred Stock and Stockholders’ Equity (Deficit) for further details on the Redeemable Convertible Preferred Stock.

Comprehensive Income (Loss)—Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss), which includes certain changes in equity that are excluded from net income (loss). Other comprehensive income (loss) consists of foreign currency translation adjustments and unrealized gains and losses from cash flow hedges. The tax benefit related to unrealized gain (loss) on cash flow hedging was $0.4 million and $0.1 million, respectively for the three and six months ended June 30, 2026, and $2.5 million for both the three and six months ended June 30, 2025.

Net Income (Loss) Per Share Attributable to Common Stockholders (“EPS”)— Basic earnings per share attributable to common stockholders is computed by dividing the earnings attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share adjusts the basic net income (loss) per share attributable to common stockholders and the weighted-average number of shares of common stock outstanding for the potentially dilutive impact of stock options, restricted stock units and any other share-settled stock compensation awards of the Company using the treasury-stock method.

Prior to the Company’s IPO, net income (loss) was attributed to common stockholders and participating securities based on their participation rights. The Company’s Preferred Stock that was subject to repurchase were considered participating securities, and the two-class method was applied in the computation of both basic and diluted EPS for periods in which such securities were outstanding. Any deemed dividends recognized related to the Preferred Stock were reflected as a reduction of income available to common stockholders. Due to the conversion rights within the Preferred Stock, the Preferred Stock was also assessed under the if-converted method for diluted EPS, and the more dilutive result of the two-class method and if-converted method was presented.

In June 2026, in connection with the Company’s IPO, each share of the Company’s then outstanding Class A common stock and Class B common stock was reclassified into common stock, and all outstanding shares of Preferred Stock converted into common stock. As of June 30, 2026, the Company had one class of common stock outstanding and no shares of Preferred Stock outstanding.

For periods prior to the Company’s IPO in which participating securities were outstanding, net loss attributable to common stockholders was not allocated to participating securities under the two-class method because the holders of these securities did not have a contractual obligation to share in the Company’s losses. Under the if-converted method, the numerator was adjusted to reverse any impacts of the convertible security, including dividends, deemed dividends and participation rights, and the denominator was increased for the number of shares issuable upon conversion, weighted for the portion of the period the securities were outstanding. For periods in which the Company reports net losses, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders because potentially dilutive common shares are anti-dilutive.

Concentration of Credit Risk and Uncertainties—The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. To reduce credit risk, management considers the following factors when determining the collectability of specific customer accounts: customer creditworthiness; past transaction history with the customer; current economic industry trends; and changes in customer payment terms. The Company maintains its cash and cash equivalents with financial institutions in amounts which exceed Federal Deposit Insurance Corporation limits.

One customer accounted for approximately 17% and 26% of accounts receivable as of June 30, 2026 and December 31, 2025, respectively.

One customer accounted for approximately 10% of revenue for both the three and six months ended June 30, 2026. No individual customer accounted for more than 10% of revenue for both the three and six months ended June 30, 2025.

Interest Expense, Net—Interest expense, net primarily consists of interest incurred on outstanding debt, including accretion of debt discount, net of interest income. Interest income primarily consists of income recognized related to cash receipts on hedges as well as interest income on cash deposits.

The components of interest expense, net are as follows within the condensed consolidated statements of operations (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2026		2025		2026		2025
Interest expense	$	36,393	$	34,604	$	73,128	$	68,542
Interest income	(3,054)		(4,566)		(4,814)		(8,900)
Interest expense, net	$	33,339	$	30,038	$	68,314	$	59,642

Deferred Offering Costs—Deferred offering costs, which include legal, accounting, printing, and other third-party fees that are incremental and directly related to the Company’s initial public offering (“IPO”), were capitalized within prepaid expenses and other current assets on the condensed consolidated balance sheets prior to the completion of the IPO. Costs not directly related to the IPO and in connection with preparing to become a public company were expensed as incurred. Upon the completion of the IPO, $19.2 million of deferred offering costs were reclassified into Additional paid-in capital as a reduction against the proceeds received from the IPO. Deferred offering costs were nil and $7.1 million as of June 30, 2026 and December 31, 2025, respectively.

Adoption of New Accounting Pronouncements—

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). This amendment introduces a practical expedient for the application of the current expected credit loss (“CECL”) model to current accounts receivable and contract assets. Effective January 1, 2026, the Company adopted ASU 2025-05 on a prospective basis and elected a practical expedient that assumes that current conditions as of the balance sheet date do not change for the remaining life of the assets. The adoption of this ASU did not have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

Recent Accounting Pronouncements Not Yet Adopted—

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (“ASU 2025-01”). The amendments in ASU 2024-03 are intended to address investor requests for more detailed expense information by requiring additional disaggregated disclosures in the notes to the financial statements for certain categories of expenses presented on the face of the income statement. As clarified by ASU 2025-01, ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. The amendments may be applied prospectively or retrospectively, and early adoption is permitted. The Company is currently assessing the potential impact that the adoption of ASU 2024-03, as clarified by ASU 2025-01, may have on its disclosures.

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 (“ASU 2025-06”), which amends certain aspects of the accounting for internally developed software costs. The amendments eliminate the concept of “development stages” and permit capitalization only when management authorizes and commits to funding a project and it is probable that the project will be completed and placed into use, while introducing a new concept of “significant development uncertainty” that precludes capitalization in cases involving unproven technology, unresolved functionality, or substantially revised performance requirements. ASU 2025-06 supersedes existing guidance on website development costs in ASC 350-50 and relocates it to ASC 350-40. The amendments are effective for annual periods beginning after December 15, 2027, including interim periods within those fiscal years, applied prospectively or retrospectively, with early adoption permitted. The Company is currently assessing the potential impact that the adoption of ASU 2025-06 may have on its condensed consolidated financial statements and related disclosures.

In November 2025, the FASB issued ASU No. 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements, which introduces five targeted improvements to better align hedge accounting with entities’ risk management activities. The update will be effective for annual reporting periods beginning after December 15, 2026, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures.

In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies the applicability of the interim reporting guidance, the types of interim reporting, and the form and content of interim financial statements in accordance with U.S. generally accepted accounting principles. Per the FASB, the amendment does not intend to change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements but rather provide clarity and improve navigability of the existing interim reporting requirements. The update will be effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	1. Description of Business Liftoff Mobile, Inc. (collectively referred to with its wholly owned subsidiaries as the “Company” or “Liftoff”) was incorporated in the state of Delaware and is headquartered in Redwood City, California, with offices in the U.S. as well as internationally in Europe and Asia. Liftoff is an independent mobile growth enablement platform, offering solutions that cover the entire app growth cycle. Initial Public Offering The Company’s registration statement on Form S-1 (the “IPO Registration Statement”) related to its initial public offering (“IPO”) was declared effective on June 3, 2026, and the Company’s common stock began trading on the Nasdaq Global Select Market on June 4, 2026. On June 5, 2026, the Company completed its IPO, in which it issued and sold 21.9 million shares of common stock, including 2.9 million shares of common stock pursuant to the underwriters’ exercise in full of their over-allotment option, at a public offering price of $23.00 per share. The Company received net proceeds of approximately $472.4 million after deducting underwriting discounts and commissions and before offering expenses. The Company used the proceeds to repay outstanding indebtedness totaling $409.2 million in aggregate principal amount, and intends to use the remainder for general corporate purposes and to cover all of the expenses of the IPO. Refer to Note 4. Credit Agreements for additional details on the debt repayment. Upon the effectiveness of the IPO registration statement, certain stock-based awards with performance-based vesting conditions tied to the IPO became probable of vesting, resulting in the recognition of stock-based compensation expense during the period in which the IPO occurred. Refer to Note 8. Stock-based Compensation for additional details. Reclassification and Stock Split On June 3, 2026, following the effectiveness of the IPO Registration Statement, the Company amended its certificate of incorporation to (i) reclassify all outstanding shares of Class A and Class B common stock into a single class of common stock (the “Reclassification”) and (ii) effect a 1.3-for-1 forward stock split of such single class of common stock (the “Stock Split”). As a result of the Stock Split, every share of issued and outstanding common stock was converted into 1.3 issued and outstanding shares of common stock, without any change in par value per share. Accordingly, an amount equal to the par value of the increased common shares resulting from the Stock Split was reclassified from capital in excess of par value to common stock. The Reclassification and Stock Split affected all shares of common stock outstanding immediately prior to the effectiveness of the Reclassification and Stock Split, as well as the number of shares of common stock authorized and available for issuance under the equity incentive plan which was in place prior to the IPO. In addition, the Stock Split resulted in an increase in the number of stock options, stock appreciation rights, and restricted stock units that were outstanding immediately prior to the effectiveness of the Stock Split, with a corresponding adjustment to the exercise price where applicable. No fractional shares were issued because of the Stock Split. Holders who would otherwise be entitled to receive a fractional share or equity award will receive a cash payment in lieu thereof. All common share and per common share amounts, including dividend per share amounts, in these condensed consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Reclassification and Stock Split. The Reclassification and Stock Split did not change (i) the total number of preferred shares authorized, issued, and outstanding, or (ii) the aggregate liquidation preference of the Preferred Stock (defined in Note 2. Summary of Significant Accounting Policies). The conversion rate and the conversion price used to determine the number of shares of common stock issuable upon the conversion of Preferred Stock have been retroactively adjusted to reflect the Stock Split.

Redeemable Convertible Preferred Stock and Stockholders’ Equity (Deficit)	6 Months Ended
	Jun. 30, 2026
Equity [Abstract]
Redeemable Convertible Preferred Stock And Stockholders’ Equity (Deficit)	7. Redeemable Convertible Preferred Stock and Stockholders’ Equity (Deficit) Redeemable Convertible Preferred Stock The Company had previously authorized and issued Redeemable Convertible Preferred Stock with a stated value of $1,000 per share, subject to adjustment for post-closing purchase price adjustments, stock dividends, stock splits, recapitalizations, or partial liquidation redemptions. The Redeemable Convertible Preferred Stock ranked senior to the Company’s common stock with respect to liquidation rights, and junior to all existing and future indebtedness. The Redeemable Convertible Preferred Stock was convertible at the option of the holder into common stock at the applicable conversion rate of 56.4972 shares per preferred share, based on a conversion price of $17.70, subject to adjustment for stock splits, dividends, recapitalizations, IPO pricing below the conversion price, and the payment of certain earnout obligations under a December 18, 2020 merger agreement. The Redeemable Convertible Preferred Stock automatically converted upon the IPO at the applicable conversion rate. In the event of partial liquidation, defined as a disposition of assets or business for net cash proceeds exceeding $430.0 million, holders had the right to elect to receive cash up to the lesser of the aggregate stated value or the cash proceeds, reducing stated value on a dollar-for-dollar basis. Upon a mandatory redemption event (change of control or liquidation event), the Company was required to redeem all outstanding Redeemable Convertible Preferred Stock at the greater of stated value or the as-converted amount, subject to funds legally available. As the occurrence of these deemed liquidation events was not solely within the Company’s control, prior to the completion of the IPO the Redeemable Convertible Preferred Stock was classified as mezzanine equity on the condensed consolidated financial statements. Holders of the Redeemable Convertible Preferred Stock were entitled to participate, on an as-converted basis, in dividends or distributions on common stock, but otherwise no dividends accrued. Holders of the Redeemable Convertible Preferred Stock were entitled to vote together with common stockholders as a single class. While any shares were outstanding, the affirmative vote of a majority of Redeemable Convertible Preferred Stock was required for certain amendments disproportionately adverse to Redeemable Convertible Preferred Stock. Upon completion of the IPO, all outstanding shares of the Redeemable Convertible Preferred Stock automatically converted into 24,011,299 shares of common stock. As of June 30, 2026, there were no shares of Redeemable Convertible Preferred Stock outstanding. In the event the Company makes a payment in respect of its existing earn-out obligations subsequent to conversion, the Company will deliver an incremental number of shares of common stock to those shareholders who held the Redeemable Convertible Preferred Stock, subject to certain transfer rules and limitations, at the time they were converted into common stock prior to such earnout obligation payment equal to the number of shares of common stock such former holders of Redeemable Convertible Preferred Stock would have incrementally been entitled to upon conversion of such shares of Preferred Stock, had such earn-out payment been made by the Company prior to the conversion of such shares of Preferred Stock. The Company determined this post-conversion feature was a freestanding instrument that did not meet the requirements of ASC 815-40 to be indexed to the Company’s own stock. Therefore, the Company recorded a post-conversion earnout share liability, which is a derivative liability, of $5.4 million as of June 30, 2025, which created a discount on the Redeemable Convertible Preferred Stock. Subsequently, this derivative liability is remeasured at fair value at each balance sheet date, and the change in fair value is included in post-conversion earnout share liability revaluation on the condensed consolidated statements of operations. Refer to Note 5. Fair Value Disclosures for further details on the post-conversion earnout share liability. Common Stock The Company’s amended and restated certificate of incorporation authorizes the Company to issue 7,000,000,000 shares of common stock, par value $0.0001 per share. Preferred Stock The Company’s amended and restated certificate of incorporation authorizes the Company to issue 700,000,000 shares of preferred stock, par value $0.0001 per share.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	6. Commitments and Contingencies Contingent Consideration—As of June 30, 2026, there is a contingent consideration arrangement of earn-out payments to former stockholders of the Company of up to $130.9 million. The contingent earn-out liabilities as of June 30, 2026 and December 31, 2025 are carried at fair value and included in other liabilities on the condensed consolidated balance sheets. Contingencies—From time to time, the Company may have certain contingent liabilities that arise in the ordinary course of business activities. The Company accrues a liability for such matters when it is probable that future expenditures will be made, and such expenditures can be reasonably estimated. Legal Proceedings—The Company is involved from time to time in litigation, claims, and proceedings. Periodically, the Company evaluates the status of each legal matter and assesses potential financial exposure. If the potential loss from any legal proceeding is considered probable and the amount can be reasonably estimated, the Company accrues a liability for the estimated loss. Significant judgment is required to determine the probability of a loss and whether the amount of the loss is reasonably estimated. The outcome of any proceeding is not determinable in advance. As a result, the assessment of a potential liability and the amount of any accrual recorded is based on the information available at the time. As additional information becomes available, the Company reassesses the potential liability related to the legal proceeding and may revise the estimates. The Company is involved in litigation arising in the ordinary course of business. It is the opinion of management and the Company’s legal counsel that these cases will be resolved without material effect on the Company’s condensed consolidated financial position, results of operations, or cash flows. Non-income Taxes—The Company may be subject to audit by various tax authorities with regard to non-income tax matters. The subject matter of non-income tax audits primarily arises from different interpretations on tax treatment and tax rates applied. The Company accrues liabilities for non-income taxes that may result from examinations by, or any negotiated agreements with, these tax authorities when a loss is probable and reasonably estimable. If a loss is reasonably possible and the loss or range of loss can be estimated, the Company discloses the reasonably possible loss.

Income Taxes	6 Months Ended
Income Taxes	Jun. 30, 2026
Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes The Company is subject to income taxes in the U.S. and in foreign jurisdictions. The Company bases interim tax accruals on an estimated annual effective tax rate applied to year-to-date income and records discrete tax items in the period in which they occur. Each quarter, the Company updates the estimated annual effective tax rate and makes a year-to-date adjustment to the tax provision as necessary. The Company’s calendar year 2026 annual effective tax rate differs from the U.S. statutory federal rate primarily due to the jurisdictional mix of earnings, valuation allowances, and nondeductible items. During the three and six months ended June 30, 2026, there were no material changes to the Company's unrecognized tax benefits.
