Use of Estimates— The preparation of the consolidated financial statements in accordance 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 income and expense during the reporting periods. The most significant estimates relate to property held for lease and the related depreciation method, impairments, and the valuation allowance associated with deferred tax assets. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other risk-based factors. Changes in estimates are reflected in reported amounts in the period in which they become known. Actual results could differ from those estimates.

Segment Information— The Company is a single segment business, which provides lease payment options to consumers to obtain durable goods from omnichannel and e-commerce partners. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results and plans for components below the consolidated unit level. Accordingly, the Company has one operating segment, and therefore, one reportable segment.

Significant customers are those which represent more than 10% of the Company’s total revenue or gross accounts receivable balance at each balance sheet date. As of December 31, 2024 and 2023, the Company did not have any customers that accounted for 10% or more of outstanding gross accounts receivable or total revenue during the years ended December 31, 2024 and 2023. Customer leases with the Company's largest merchant, Wayfair Inc., represented more than 10% of our total revenue for the years ended December 31, 2024 and 2023.

Cash and Cash Equivalents— As of December 31, 2024 and 2023, cash consists primarily of checking and savings deposits. The Company holds certain cash equivalents, which consist of highly liquid investments with original maturities of three months or less at the time of purchase.

Restricted Cash— The Company classifies all cash whose use is limited by contractual provisions as restricted cash. Restricted cash as of December 31, 2024 and 2023 consists primarily of customer lease payments received into a collection account pending release by the Company's lender. Restrictions are released on a weekly basis pursuant to completion of waterfall and borrowing base requirements. All of the Company’s restricted cash is classified as current due to its short-term nature.

Property Held for Lease, Net of Accumulated Depreciation and Impairment— Property held for lease consists of furniture, mattresses, customer electronics, appliances, and other durable goods offered for lease-purchase in the normal course of business. Such property is provided to customers pursuant to a lease-purchase agreement with a minimum lease term; typically one week, two weeks, or one month. The renewal periods of the initial lease term of the agreement are typically 12 or 18 months. Customers may terminate a lease agreement at any time without penalty. The average customer continues to lease the property for approximately 8 months because the customer either exercises the early lease-purchase option (buyout) or terminates the lease-purchase agreement prior to the end of the 12 or 18 month renewal periods. As a result, property held for lease is classified as a current asset on the consolidated balance sheets.

Property held for lease is recorded at cost, excluding shipping costs, and is carried at net book value. Depreciation for property held for lease is determined using the income forecasting method and is included within cost of revenue. The Company’s income forecasting method evaluates the patterns of the Company’s historical property held for lease portfolio to apply depreciation rates to the Company’s current property held for lease portfolio. Property held for lease is depreciated in the proportion of expected rents received to total expected rents to be received based on the Company’s historical data of lease performance. The utilization of rental merchandise occurs during periods of rental and directly coincides with the pattern of rental revenue receipts over the rental purchase agreement period. The Company also considers other qualitative factors, such as current and forecasted customer payment trends, and other risk-based factors as a component of its forecasting methodology.

The Company provides for impairment for the undepreciated balance of the property held for lease assuming no salvage value with a corresponding charge to cost of revenue. The provision for write-offs represents estimated losses based on historical results, which are incurred but not yet identified. Actual write-offs may differ from this estimate.

The Company applies its depreciation to property held for lease as follows: (1) typical depreciation based on historical patterns of customer payments when an item is leased for the full lease duration; (2) accelerated depreciation for impaired leases, based on historical patterns of lease impairment, and (3) accelerated depreciation for leases where an early purchase option (buyout) is exercised, based on historical patterns of lease buyouts.

The Company accelerates depreciation equal to the undepreciated net book value of property buyouts as buyouts occur with a corresponding charge to cost of revenue based on historical trends, such that the recorded amount closely approximates current actual buyouts during the period. The Company periodically evaluates fully depreciated property held for lease, net and when it is determined there is no future economic benefit, the cost of the assets are written off and the related accumulated depreciation is reversed.

Capitalized Software—The Company capitalizes certain development costs incurred in connection with its internal use software. Costs incurred in the preliminary stages of development are expensed as incurred. Capitalization of costs begins when the preliminary project stage is completed, and it is probable that the project will be completed and used for its intended

function. Once an application has reached the development stage, internal and external costs, if direct and incremental, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional features and functionality. Maintenance costs are expensed as incurred. Internal use software is amortized on a straight-line basis over its estimated useful life, generally three years. Capitalized software cost is included within the capitalized software and intangible assets, net line item of our consolidated balance sheets. Amortization of capitalized software is included in general and administrative expenses in our consolidated statements of operations and comprehensive loss.

Debt Issuance Costs— Costs incurred in connection with the issuance of the Company’s revolving line of credit (“RLOC”) and senior secured term loan ("Term Loan") have been recorded as a direct reduction against the debt and amortized over the life of the associated debt as a component of interest expense. The amortization of the Term Loan issuance costs utilizes the effective interest method, and the amortization of the RLOC debt issuance costs utilizes the straight-line method, which is not materially different compared to the effective interest method. The amortization of debt issuance costs is recorded and included in interest expense and other fees in our consolidated statements of operations and comprehensive loss.

Rental Revenue— Lease-purchase agreements, which comprise the majority of total revenue, fall within the scope of ASC 842, Leases under lessor accounting and revenue is recognized in the period it is earned and cash is collected. Property held for lease is leased to customers pursuant to lease-purchase agreements with an initial term: typically one week, two weeks, or one month, with non-refundable lease payments. Generally, the customer has the right to acquire title either through a 90-day promotional pricing option, an early lease-purchase option (buyout), or by completing all lease renewal payments, generally over 12 or 18 months. On any current lease, customers have the option to terminate the agreement at any time without penalty, in accordance with the lease term. Amounts received from customers who elect early lease-purchase options (buyouts) are included in rental revenue. Lease payments received prior to their due dates are deferred and recorded as unearned revenue and are recognized as rental revenue in the period in which the revenue is earned. Rental revenue also includes an initial agreed-upon amount for executing customer lease-purchase agreements. Payments are received upon submission of the applications and execution of the lease-purchase agreements. Services are considered to be rendered and revenue earned over the lease term.

Revenues from leases that originated from merchants with a direct or waterfall integration are generally recorded net of sales taxes as sales tax is collected from each customer's lease payment and a sales tax payable is recorded for remittance to the respective state. For Katapult Pay transactions, all sales tax is paid by the Company upon purchase of the goods and is recorded in the cost basis of the capitalized property held for lease. Revenue is recognized for leases originating through Katapult Pay in the period it is earned and cash is collected.

Other Revenue— Other revenue consists primarily of the sale of property held for lease (and lease agreements) to third parties and other immaterial sources of income from third party relationships. The sale of property held for lease is considered recurring and ordinary in nature to the Company’s business, and as such, these sales are accounted for within the scope of ASC 606, Revenue from Contracts with Customers. The payment terms require a fixed amount paid upfront by the third-party buyer based on a negotiated percentage of the collectible value of the unpaid balance of the delinquent leases being sold and is not subject to future adjustments or recourse provisions.. Revenue from such sales is recognized at the point in time when control of the remaining unpaid delinquent lease balances and lease agreements are transferred to the third party buyer, which occurs upon execution of the sale agreement and receipt of consideration. Other revenue of $3.2 million and $3.2 million was recognized for the years ended December 31, 2024 and 2023, respectively.

Stock-Based Compensation— In accordance with ASC 718, compensation expense related to stock-based awards are measured and recorded based on the fair value of those awards as determined on the date of the grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period and uses the straight-line method to recognize stock-based compensation. The Company historically used the Black-Scholes-Merton (“Black-Scholes”) option-pricing model to determine the estimated fair value of stock option awards. The Black-Scholes option-pricing model requires estimates of highly subjective assumptions, which affect the fair value of each stock option. The Company has not issued any stock options during the years ended December 31, 2024 or December 31, 2023. Forfeitures are accounted for as they are incurred.

Income Taxes— The Company accounts for income taxes under the asset and liability method pursuant to ASC 740, Income Taxes. Under this method, the Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our consolidated financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax basis of assets and

The Company recognizes deferred tax assets to the extent that these assets are more likely than not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If the Company determines that the Company would be able to realize deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to unrecognized tax benefits in the income tax expense line in the accompanying consolidated statements of operations and comprehensive loss. As of December 31, 2024 and 2023, no accrued interest or penalties are included on the related tax liability line in the consolidated balance sheets.

Under the two-class method, basic net loss per share available to stockholders is calculated by dividing the net loss available to stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share available to stockholders is computed by giving effect to all potentially dilutive common stock equivalents outstanding for the period. In periods in which the Company reports a net loss available to stockholders, diluted net loss per share available to stockholders would be the same as basic net loss per share available to stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported net loss available to common shareholders during the years ended December 31, 2024 and 2023, respectively.

Fair Value Measurements— Certain assets and liabilities are required to be carried at fair value in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The Company uses a three-level hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities.

Advertising— The Company expenses advertising costs as incurred. Total advertising costs were $0.5 million and $0.1 million for the years ended December 31, 2024 and 2023, respectively, and are classified within operating expenses in the consolidated statements of earnings.

Recent Accounting Pronouncements Not Yet Adopted— In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU will improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. This update is effective for public entities for annual periods beginning after December 15, 2024 with early adoption permitted for annual financial statements that have not yet been issued or made available for issuance. The Company is evaluating the impact of this ASU.

In November 2024, the FASB issues ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. This update is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is evaluating the impact of adopting ASU 2024-03.
