Except as the context requires otherwise, as used herein, “Registrants” refers to Prosper Marketplace, Inc. (“PMI”), a Delaware corporation, and its wholly owned subsidiary, Prosper Funding LLC (“PFL”), a Delaware limited liability company; “we,” “us,” “our,” “Prosper,” and the “Company” refers to (i) PMI, (ii) its wholly owned subsidiaries, PFL, BillGuard, Inc. (“BillGuard”), a Delaware corporation, and Prosper Healthcare Lending LLC (“PHL”), a Delaware limited liability company, and (iii) its variable interest entities, Prosper Warehouse I Trust (“PWIT,” terminated March 28, 2024), a Delaware statutory trust, Prosper Warehouse II Trust (“PWIIT,” terminated September 25, 2023), a Delaware statutory trust, Prosper Marketplace Issuance Trust, Series 2023-1 (“PMIT 2023-1”), a Delaware statutory trust, Prosper Marketplace Issuance Trust, Series 2024-1 (“PMIT 2024-1”), a Delaware statutory trust, and Prosper Grantor Trust (“PGT”), a Delaware statutory trust, on a consolidated basis; and “Prosper Funding” refers to PFL and its wholly owned subsidiary, Prosper Depositor LLC, a Delaware limited liability company, on a consolidated basis. In addition, the unsecured personal loans originated through our marketplace are referred to as “Borrower Loans,” and the borrower payment dependent notes issued through our marketplace, whether issued by PMI or PFL, are referred to as “Notes.” Investors currently invest in Borrower Loans through two channels: (i) the “Note Channel,” which allows investors to purchase Notes from PFL, the payments of which are dependent on the payments made on the corresponding Borrower Loan; and (ii) the “Whole Loan Channel,” which allows accredited and institutional investors to purchase Borrower Loans in their entirety directly from PFL. The Notes available to Note Channel investors are distinguishable from notes held by certain third party investors pursuant to Prosper’s securitization transactions, which are referred to herein as “Notes Issued by Securitization Trust.” Finally, although historically the Company has referred to investors as “lender members,” PFL calls them “investors” herein to avoid confusion since WebBank is the lender for Borrower Loans originated through our marketplace.

Forward-Looking Statements

This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements include all statements that do not relate solely to historical or current facts, and can generally be identified by the use of words such as “may,” “believe,” “expect,” “project,” “estimate,” “intend,” “anticipate,” “plan,” “continue” or similar expressions. These statements may appear throughout this Quarterly Report on Form 10-Q, including the sections titled “Business,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements inherently involve many risks and uncertainties that could cause actual results to differ materially from those projected in these statements. Where, in any forward-looking statement, PFL or PMI expresses an expectation or belief as to future results or events, such expectation or belief is based on the current plans and expectations of their respective managements, expressed in good faith and is believed to have a reasonable basis. Nevertheless, there can be no assurance that the expectation or belief will result or be achieved or accomplished.

The following include some but not all of the factors that could cause actual results or events to differ materially from those anticipated:

•the performance of the Notes, which, in addition to being speculative investments, are special, limited obligations that are not guaranteed or insured;

•PFL’s ability to make payments on the Notes, including in the event that borrowers fail to make payments on the corresponding Borrower Loans;

•our ability to attract potential borrowers and investors to our personal loan marketplace, and borrowers to our unsecured credit card (“Credit Card”) product, and secured digital home equity line of credit and home equity loan (together, the “Home Equity Products”);

•the reliability of the information about borrowers that is supplied by borrowers including actions by some borrowers to defraud investors;

•our ability to service the Borrower Loans, and our ability or the ability of a third-party debt collector to pursue collection against any borrower, including in the event of fraud or identity theft;

•credit risks posed by the credit worthiness of borrowers of our Personal Loan and Credit Card products and the effectiveness of our credit rating systems;

•potential efforts by state regulators or litigants to impose liability that could affect PFL’s (or any subsequent assignee’s) ability to continue to charge to borrowers the interest rates that they agreed to pay at origination of their loans;

•the impact of future economic conditions on the performance of the Notes and the loss rates for the Notes;

•the growth and performance of the recently-launched Credit Card product and the Home Equity products;

•our compliance with applicable local, state and federal law, including the Investment Advisers Act of 1940, the Investment Company Act of 1940 and other laws;

•our compliance with applicable regulations and regulatory developments or court decisions affecting our business;

•potential efforts by state regulators or litigants to characterize PFL or PMI, rather than WebBank, as the lender of the loans originated through our marketplace;

•the application of federal and state bankruptcy and insolvency laws to borrowers and to PFL and PMI;

•the impact of borrower delinquencies, defaults and prepayments on the returns on the Notes;

•the impact of rising interest rates and inflation on our business, results of operations, financial condition and future prospects;

•the lack of a public trading market for the Notes and the current lack of any trading platform on which investors can resell the Notes;

•the federal income tax treatment of an investment in the Notes and the PMI Management Rights; and

•our ability to prevent security breaches, disruptions in service, and comparable events that could compromise the personal and confidential information held on our data systems, reduce the attractiveness of the platform or adversely impact our ability to service Borrower Loans.

There may be other factors that may cause actual results to differ materially from the forward-looking statements in this Quarterly Report on Form 10-Q. We can give no assurances that any of the events anticipated by the forward-looking statements will occur or, if any of them does occur, what impact they will have on our results of operations and financial condition. You should carefully read the factors described in the “Risk Factors” sections of this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2023 for a description of certain risks that could, among other things, cause our actual results to differ from these forward-looking statements.

All forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q and are expressly qualified in their entirety by the cautionary statements included in this Quarterly Report on Form 10-Q. We undertake no obligation to update or revise forward-looking statements that may be made to reflect events or circumstances that arise after the date made or to reflect the occurrence of unanticipated events, other than as required by law.

PROSPER MARKETPLACE, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

Prosper Marketplace, Inc. (“PMI” or the “Company”) was incorporated in the state of Delaware on March 22, 2005. Except as the context requires otherwise, as used in these notes to the condensed consolidated financial statements of PMI, “Prosper,” “we,” “us,” and “our” refer to PMI and its wholly-owned subsidiaries, on a consolidated basis.

The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and disclosure requirements for interim financial information and the requirements of Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2023. The balance sheet at December 31, 2023 has been derived from the audited financial statements at that date. Management believes these unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

PMI did not have any items of other comprehensive income or loss for any of the periods presented in the condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023.

The preparation of Prosper’s condensed consolidated financial statements and related disclosures in conformity with US GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in Prosper’s financial statements and accompanying notes. Management bases its estimates on historical experience and on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities. These judgments, estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions.

The accompanying interim condensed consolidated financial statements include the accounts of PMI, its wholly-owned subsidiaries and consolidated VIEs. All intercompany balances have been eliminated in consolidation.

Notes Issued by Securitization Trust are notes held by certain third-party investors pursuant to Prosper’s securitization transactions, and are distinguishable from the borrower payment dependent Notes available to investors through the Company’s Note Channel.

2. Summary of Significant Accounting Policies

Prosper’s significant accounting policies are included in Note 2, Summary of Significant Accounting Policies, in Prosper’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no changes to these accounting policies during the first three months of 2024.

Fair Value Measurements

Financial instruments measured at fair value consist principally of Borrower Loans (Note 4), Loans Held for Sale (Note 4), Servicing Assets (Note 6), Credit Card Derivative (Note 5), Loan Trailing Fee Liabilities (Note 10), Debt (Note 11) and Convertible Preferred Stock Warrant Liability (Note 13). The estimated fair values of other financial instruments, including Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable and Accrued Liabilities, and Payable to Investors approximate their carrying values because of their short-term nature. The estimated fair values of the Term Loan and Warehouse Lines (Note 11) do not approximate their carrying values due primarily to differences in the stated and market rates associated with these instruments.

Refer to Note 8, Fair Value of Assets and Liabilities, for additional fair value disclosures.

Restricted Cash

Restricted cash consists primarily of cash deposits, money market funds and short-term certificate of deposit accounts held as collateral as required for loan funding and servicing activities, and cash that investors or Prosper have on the marketplace that has not yet been invested in Borrower Loans or disbursed to the investor.

Borrower Loans, Loans Held for Sale and Notes

Borrower Loans are funded either through the Note Channel or through the Whole Loan Channel. Through the Note Channel, Prosper purchases Borrower Loans from WebBank, then issues Notes and holds the Borrower Loans until maturity. The obligation to repay a series of Notes issued through the Note Channel is dependent upon the repayment of the associated Borrower Loan. Borrower Loans funded and Notes issued through the Note Channel are carried on Prosper’s condensed consolidated balance sheets as assets and liabilities, respectively.

Until March 2024, Prosper used Warehouse Lines to purchase Loans Held for Sale that could be subsequently contributed to securitization transactions or sold to investors. Loans Held for Sale were included in “Loans Held for Sale, at Fair Value” on the condensed consolidated balance sheets. In September 2023 and March 2024, in connection with the securitization transactions discussed below, the Loans Held for Sale in these Warehouse Lines were fully contributed to the securitization entities or purchased by Prosper, and the outstanding balances of the Warehouse Lines were fully paid down. See Note 11, Debt for more details on the termination of the Warehouse Lines.

In September 2023 and March 2024, Prosper closed two separate securitization transactions, PMIT 2023-1 and PMIT 2024-1, respectively, with personal loans previously funded through its PWIIT Warehouse Line and PWIT Warehouse Line, respectively. These newly formed securitization entities issued notes acquired by third parties and residual certificates acquired by PMI (a majority owned affiliate of PFL, the sole sponsor of the securitizations). PMIT 2023-1 and PMIT 2024-1 are deemed consolidated VIEs, and as a result the Borrower Loans they hold are presented in “Borrower Loans, at Fair Value,” and the notes sold to third-party investors are included in “Notes Issued by Securitization Trust” on the accompanying condensed consolidated balance sheets. See Note 7, Securitizations, for additional disclosures related to these securitizations.

Borrower Loans and Loans Held for Sale are purchased from WebBank. Prosper places Borrower Loans and Loans Held for Sale on non-accrual status when they are 120 days past due. When a loan is placed on non-accrual status, Prosper stops accruing interest and reverses all accrued but unpaid interest as of such date. Additionally, Prosper charges-off Borrower Loans and Loans Held for Sale when they are 120 days past due. The fair value of loans 120 or more days past due generally consists of the expected recovery from debt sales in subsequent periods.

Prosper has elected the fair value option for Borrower Loans, Loans Held for Sale and Notes. Changes in the fair value of Borrower Loans funded through the Note Channel are largely offset by the changes in fair value of Notes due to the borrower payment-dependent design of the Notes. Changes in the fair value of Borrower Loans and Loans Held for Sale are recorded through Proper's earnings and Prosper collects interest on Borrower Loans and Loans Held for Sale. Changes in the fair values of Borrower Loans, Loans Held for Sale and Notes are included in “Change in Fair Value of Financial Instruments” on the accompanying condensed consolidated statements of operations.

Prosper primarily uses a discounted cash flow model to estimate the fair value of Borrower Loans, Loans Held for Sale and Notes. The key assumptions used in the valuation include default rates and prepayment rates derived primarily from historical performance, and discount rates based on estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

Credit Card Derivative

The Company evaluated the terms of its Credit Card program agreement (the “Credit Card Program Agreement”) with Coastal Community Bank (“Coastal”) and determined that it contained features that met the definition of derivatives under Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging. These features are freestanding financial instruments (as defined under ASC 480, Distinguishing Liabilities from Equity), and have been valued separately as derivatives. A right of offset exists between the derivatives, and they are presented net on the accompanying consolidated balance sheets. Changes in the fair value of the Credit Card Derivative, as well as settled transactions from the Credit Card portfolio, are recorded in “Change in Fair Value of Financial Instruments” on the accompanying condensed consolidated statements of operations.

Refer to Note 5, Credit Card, for additional details on revenues and expenses related to the Credit Card product, and to Note 8, Fair Value of Assets and Liabilities, for additional details related to the valuation methodology for the Credit Card Derivative.

Term Loan

Prosper entered into a Credit Agreement, which provided for a Term Loan with a third-party financial institution in November 2022, which is more fully described in Note 11, Debt. This Term Loan is carried at amortized cost, net of discounts and issuance costs, which are subsequently amortized to Interest Expense on Term Loan over the life of the underlying agreement.

Interest Expense on Term Loan is presented as a component of Expenses on the accompanying condensed consolidated statements of operations, except for any portion associated with Term Loan proceeds used to purchase Loans Held for Sale through the Company’s Warehouse Lines, which is presented in “Interest Expense on Financial Instruments” as a component of Net Interest Income on the accompanying condensed consolidated statement of operations.

Leases

Management determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and operating lease liabilities are included on the Condensed Consolidated Balance Sheets in Property and Equipment, Net and in Other Liabilities, respectively. For certain leases with original terms of twelve months or less, PMI recognizes the lease expense as incurred and does not record ROU assets and lease liabilities.

If a contract contains a lease, management evaluates whether it should be classified as an operating or finance lease. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. As most of PMI's leases do not provide an implicit rate, management uses an incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The operating lease ROU assets are evaluated for impairment utilizing the same impairment model used for Property and Equipment.

Consolidation of Variable Interest Entities

The determination of whether to consolidate a VIE in which we have a variable interest requires a significant amount of analysis and judgment regarding whether we are the primary beneficiary of a VIE due to our holding a controlling financial interest in the VIE. A controlling financial interest in a VIE exists if we have both the power to direct the VIE’s activities that most significantly affect the VIE’s economic performance and a potentially significant economic interest in the VIE. The determination of whether an entity is a VIE considers factors, such as (i) whether the entity’s equity investment at risk is insufficient to allow the entity to finance its activities without additional subordinated financial support and (ii) whether a holder’s equity investment at risk lacks any of the following characteristics of a controlling financial interest: the direct or indirect ability through voting rights or similar rights to make decisions about a legal entity’s activities that have a significant effect on the entity’s success, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the legal entity.

Management regularly reviews and reconsiders its previous conclusions regarding the status of an entity as a VIE and whether we are required to consolidate or deconsolidate such VIE in the consolidated financial statements.

Recent Accounting Pronouncements

Accounting Standards Issued, to be Adopted by the Company in Future Periods

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Reference Rate Reform (Topic 848),” which provides optional expedients and exceptions for applying GAAP on contract modifications and hedge accounting, in order to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative referenced rates, such as the Secured Overnight Financing Rate. The optional guidance, which became effective on March 12, 2020, could be applied through December 31, 2022. In December 2022, the FASB issued No 2022-06 extending the sunset date of the relief provided under ASU No. 2020-04 to December 31, 2024. The Company amended its agreements and transitioned to SOFR for contracts that previously referenced LIBOR. The Company continues to evaluate potential future impacts that may result from the discontinuation of LIBOR or other reference rates as well as the accounting provided in this update on our financial condition, results of operations, and cash flows.

In October 2023, the FASB issued ASU No. 2023-06, “Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission’s Disclosure Update and Simplification Initiative”. The amendments in this update modify the disclosure or presentation requirements of a variety of Topics in the ASC in response to the SEC’s Release No. 33-10532, “Disclosure Update and Simplification Initiative”, and align the ASC’s requirements with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective. Early adoption is prohibited. The Company does not expect the adoption of this ASU to have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which updates reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which enhances effective tax rate reconciliation disclosure requirements and provides clarity to the disclosures of income taxes paid, income before taxes and provision for income taxes. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this update should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Other recent accounting pronouncements issued by the FASB did not, or are not believed by management to, have a material impact on the Company’s present or future financial statements.

As of March 31, 2024, outstanding Borrower Loans had original terms to maturity of 24, 36, 48 or 60 months, had monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and had various original maturity dates through March 2029. As of December 31, 2023, outstanding Borrower Loans had original terms to maturity of 24, 36, 48 or 60 months, had monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and had various original maturity dates through December 2028.

As of March 31, 2024, Borrower Loans that were 90 days or more delinquent had an aggregate principal amount of $7.2 million and a fair value of $1.1 million. As of December 31, 2023, Borrower Loans that were 90 days or more delinquent had an aggregate principal amount of $7.0 million and a fair value of $1.3 million. Prosper places loans on non-accrual status when they are over 120 days past due. As of March 31, 2024 and December 31, 2023, Borrower Loans in non-accrual status had a fair value of $1.1 million and $1.0 million, respectively.

Loans Held for Sale

As of March 31, 2024, the outstanding balance of Loans Held for Sale was reduced to zero following the contribution of loans held in consolidated warehouse trusts to the PMIT 2023-1 and PMIT 2024-1 securitization transactions in September 2023 and March 2024, respectively, as more fully described in Note 7, Securitizations. As of December 31, 2023, outstanding Loans Held for Sale had original terms to maturity of either 24, 36, 48 or 60 months, had monthly payments with fixed interest rates ranging from 6.00% to 33.00% and had various original maturity dates through July 2028. Interest income earned on Loans Held for Sale by the Company was $4.3 million and $16.5 million for the three months ended March 31, 2024 and March 31, 2023, respectively.

As of December 31, 2023, Loans Held for Sale that were 90 days or more delinquent had an aggregate principal amount of $2.1 million and a fair value of $0.5 million. Prosper places loans on non-accrual status when they are over 120 days past due. As of December 31, 2023, Loans Held for Sale in non-accrual status had a fair value of $0.2 million.

5. Credit Card

In March 2024, the Company executed an amendment to the Credit Card Program Agreement that revised the allocation of customer accounts designated as Prosper accounts (“Prosper Allocations”) and Coastal accounts (“Coastal Allocations”) from 90% and 10%, respectively, to 95% and 5%, respectively. Additionally, the maximum outstanding Credit Card principal balance for Prosper Allocations was increased from $300 million to $350 million. These changes went into effect on April 1, 2024.

For the three months ended March 31, 2024 and 2023, the Company recognized $9.1 million and $6.1 million, respectively, of unrealized gains from fair value changes on the Credit Card Derivative. Changes from settled transactions underlying the Credit Card Derivative, including income from debt sales on charged off balances, were a loss of $2.7 million and a loss of $1.5 million for the three months ended March 31, 2024 and 2023, respectively. These unrealized and settled gains and losses are included in Changes in Fair Value of Financial Instruments on the accompanying condensed consolidated statements of operations.

The Company records revenue from various fees generated from the Credit Card program, including interchange fees, annual fees and late fees, net of a portion of the interchange fees that must be remitted to Coastal. These fees are included in

18

Transaction Fees, Net on the accompanying condensed consolidated statements of operations. For the three months ended March 31, 2024 and 2023, these fees totaled $5.8 million and $3.4 million, respectively.

Under the program agreement, Prosper is responsible for servicing the entire underlying Credit Card portfolio. Coastal pays the Company a 1% per annum servicing fee on the daily outstanding principal balance of receivables designated as Coastal Allocations. To the extent these servicing fees do not exceed the market servicing rate a market participant would require to service the entire Credit Card portfolio, the Company records a servicing obligation liability and measures it at fair value through the servicing period. The net balance of this servicing obligation liability is included in “Other Liabilities” on the accompanying condensed consolidated balance sheets (see Note 10, Other Liabilities). Changes in the fair value of the servicing obligation liability are recorded in Servicing Fees, Net on the accompanying condensed consolidated statements of operations, and totaled a gain of $0.9 million and a loss of $0.9 million for the three months ended March 31, 2024 and 2023, respectively.

6. Servicing Assets

Prosper accounts for Servicing Assets at their estimated fair values with changes in fair values recorded in Servicing Fees, Net on the accompanying condensed consolidated statement of operations. The initial asset or liability is recognized when Prosper sells Borrower Loans to unrelated third-party buyers through the Whole Loan Channel and the servicing rights are retained. The Servicing Assets are measured at fair value throughout the servicing period. The Company recognized a loss on the sale of such Borrower Loans in the amount of $10.5 million and $1.4 million for the three months ended March 31, 2024 and 2023, respectively, recorded in (Loss) Gain on Sale of Borrower Loans on the condensed consolidated statements of operations.

As of March 31, 2024, Borrower Loans that were sold but for which Prosper retained servicing rights had a total outstanding principal balance of $3.1 billion, original terms to maturity of 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and various original maturity dates through March 2029. As of December 31, 2023, Borrower Loans that were sold but for which Prosper retained servicing rights had a total outstanding principal balance of $3.1 billion, original terms to maturity of either 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and various original maturity dates through December 2028.

Contractually-specified servicing fees and ancillary fees totaling $7.4 million and $8.2 million for the three months ended March 31, 2024 and 2023, respectively, are included in the condensed consolidated statements of operations in Servicing Fees, Net.

Fair Value Valuation Method

Prosper uses a discounted cash flow valuation methodology generally consisting of developing an estimate of future cash flows that are expected to occur over the life of a financial instrument and then discounts those cash flows at a rate of return that results in the fair value amount.

Significant unobservable inputs presented in the table within Note 8 below are those that Prosper considers significant to the estimated fair values of the Level 3 Servicing Assets. The following is a description of the significant unobservable inputs provided in the table.

Market Servicing Rate

Prosper estimates adequate market servicing rates that would fairly compensate a substitute servicer should one be required, which includes the profit that would be demanded in the marketplace. This rate is stated as a fixed percentage of outstanding principal balance on a per annum basis. With the assistance of a valuation specialist, Prosper estimates these market servicing rates based on observable market rates for other loan types in the industry and bids from subservicing providers, adjusted for the unique loan attributes that are present in the specific loans that Prosper sells and services and information from backup service providers.

Discount Rate

The discount rate is a rate of return used to discount future expected cash flows to arrive at a present value, which represents the fair value of the loan servicing rights. We use a range of discount rates for the Servicing Assets based on comparable observed valuations of similar assets and publicly available disclosures related to servicing valuations, with comparability adjustments made to account for differences with Prosper’s servicing assets.

Default Rate

The default rate presented in Note 8 is an annualized, average estimate considering all Borrower Loan categories (i.e., risk ratings and duration), and represents an aggregate of conditional default rate curves for each credit grade or Borrower Loan

19

category. Each point on a particular Borrower Loan category’s curve represents the percentage of principal expected to default per period based on the term and age of the underlying Borrower Loans. The assumption regarding defaults directly reduces servicing revenues because the amount of servicing revenues received is based on the amount collected each period.

Prepayment Rate

The prepayment rate presented in Note 8 is an annualized, average estimate considering all Borrower Loan categories (i.e., risk ratings and duration), and represents an aggregate of conditional prepayment rate curves for each credit grade or Borrower Loan category. Each point on a particular Borrower Loan category’s curve represents the percentage of principal expected to prepay per period based on the term and age of the underlying Borrower Loans. Prepayments reduce servicing revenues as they shorten the period over which we expect to collect fees on the Borrower Loans, which is used to project future servicing revenues.

7.  Securitizations

Prosper served as the sole sponsor of two securitizations of unsecured personal whole loans facilitated through the Company’s marketplace that were previously held in consolidated warehouse trusts: PMIT 2023-1 in September 2023 and PMIT 2024-1 in March 2024, respectively. These transactions benefit the Company by reducing the financing costs associated with the underlying Borrower Loans. Both securitizations issued senior notes and residual certificates to finance the purchase of Borrower Loans. The notes were sold to third-party investors and a majority-owned affiliate of the sole sponsor of the securitizations, PFL, retained the residual certificates. In addition to the residual certificates, Prosper’s continued involvement includes loan servicing responsibilities over the life of the underlying loans.

PMIT 2023-1 and PMIT 2024-1 (together, the “PMITs”) are deemed VIEs, and the Company consolidates them as the primary beneficiary. Through Prosper’s role as the servicer, it has the power to direct the activities that most significantly affect the PMITs’ economic performance. Additionally, because the Company holds the residual certificates, it has a variable interest that could potentially be significant to the PMITs. In evaluating whether Prosper is the primary beneficiary, management considers both qualitative and quantitative factors regarding the nature, size and form of the Company’s involvement with the PMITs. Management assesses whether Prosper is the primary beneficiary of the PMITs on an on-going basis. For the PMITs, the creditors have no recourse to the general credit of Prosper and the liabilities of the PMITs can only be settled by their respective assets. Additionally, the assets of the PMITs can be used only to settle obligations of the PMITs. Because Prosper consolidates the PMITs’ securitization trusts, the Borrower Loans held in those trusts are included in “Borrower Loans, at Fair Value,” and the notes sold to third-party investors are presented in “Notes Issued by Securitization Trust” on the condensed consolidated balance sheets. Because Prosper holds 100% of the residual certificates issued by the PMITs, they eliminate through consolidation and are thus not presented on the condensed consolidated balance sheets.

PMIT 2023-1

In September 2023, Prosper closed the PMIT 2023-1 securitization. Based on the terms of the underlying agreements, the PWIIT Warehouse Line (see Note 11, Debt) agreed to contribute Borrower Loans with an aggregate outstanding principal balance of $275.9 million as of the established cutoff date of August 31, 2023, to the PMIT 2023-1 securitization. On September 25, 2023, these Borrower Loans, with an updated aggregate outstanding principal balance of $266.1 million, were contributed to the PMIT 2023-1 securitization.

The notes under PMIT 2023-1 were issued in five classes: Class A in the amount of $165.5 million, Class B in the amount of $25.4 million, Class C in the amount of $25.1 million, Class D in the amount of $22.3 million and Class E in the amount of $13.1 million (collectively, the “2023-1 Notes”). The Class A, Class B, Class C, Class D and Class E notes bear interest at fixed rates of 7.06%, 7.48%, 8.29%, 11.24% and 15.49%, respectively. Principal and interest payments began in October 2023 and are payable monthly. The 2023-1 Notes are recorded at amortized cost, net of original issue discounts totaling approximately $0.8 million. These discounts, along with debt issuance costs incurred of $2.7 million, are deferred and amortized into interest expense over the contractual lives of the 2023-1 Notes using the effective interest method. As of March 31, 2024, the outstanding principal and accrued interest of the 2023-1 Notes was $186.2 million, secured by an aggregate outstanding principal balance of $196.5 million of borrower loans, and approximately $13.5 million in cash collections held in collateral and reserve accounts included in “Restricted Cash” on the condensed consolidated balance sheets.

PMIT 2024-1

In March 2024, Prosper closed the PMIT 2024-1 securitization. Based on the terms of the underlying agreements, the PWIT Warehouse Line (see Note 11, Debt) agreed to contribute Borrower Loans with an aggregate outstanding principal balance of $148.9 million as of the established cutoff date of February 14, 2024, to the PMIT 2024-1 securitization. On March

20

28, 2024, these Borrower Loans, with an updated aggregate outstanding principal balance of $138.0 million, were contributed to the PMIT 2024-1 securitization.

The notes under PMIT 2024-1 were issued in four classes: Class A in the amount of $105.2 million, Class B in the amount of $10.8 million, Class C in the amount of $10.3 million and Class D in the amount of $10.2 million (collectively, the “2024-1 Notes”). The Class A, Class B, Class C and Class D notes bear interest at fixed rates of 6.12%, 6.13%, 6.96%, 10.98%, respectively. The 2024-1 Notes are recorded at amortized cost, net of debt issuance costs incurred of $1.5 million. These debt issuance costs are deferred and amortized into interest expense over the contractual lives of the 2024-1 Notes using the effective interest method. As of March 31, 2024, the outstanding principal and accrued interest of the 2024-1 Notes was $136.6 million, secured by an aggregate outstanding principal balance of $137.6 million of borrower loans included in “Borrower Loans, at Fair Value” on the condensed consolidated balance sheets, and approximately $14.1 million in cash collections held in collateral and reserve accounts included in “Restricted Cash” on the condensed consolidated balance sheets.

8. Fair Value of Assets and Liabilities

Prosper measures the fair value of assets and liabilities in accordance with its fair value hierarchy which prioritizes information used to measure fair value and the effect of fair value measurements on earnings and provides for enhanced disclosures determined by the level within the hierarchy of information used in the valuation. The Company applies this framework whenever other standards require (or permit) assets or liabilities to be measured at fair value.

Assets and liabilities carried at fair value on the balance sheets are classified among three levels based on the observability of the inputs used to determine fair value:

Level 1 — The valuation is based on quoted prices in active markets for identical instruments.

Level 2 — The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation methodologies for which all significant assumptions are observable in the market.

Level 3 — The valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the instrument. Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar methodologies, which incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument or valuations that require significant management judgment or estimation.

Fair values of assets or liabilities are determined based on the fair value hierarchy, which requires an entity to maximize the use of quoted prices and observable inputs and to minimize the use of unobservable inputs when measuring fair value. Various valuation methodologies are utilized, depending on the nature of the financial instrument, including the use of market prices for identical or similar instruments, or discounted cash flow models. When possible, active and observable market data for identical or similar financial instruments are utilized. Alternatively, fair value is determined using assumptions that management believes a market participant would use in pricing the asset or liability.

Financial Instruments Recorded at Fair Value

The fair value of the Borrower Loans, Loans Held for Sale, Notes, Servicing Assets and Liabilities and loan trailing fee liability are estimated using discounted cash flow methodologies based upon a set of valuation assumptions. The primary assumptions used in the discounted cash flow model include default and prepayment rates primarily derived from historical performance and discount rates applied to each credit grade based on the perceived credit risk of each credit grade.

The fair value of the Credit Card Derivative is also estimated using a discounted cash flow model using certain assumptions. The key assumptions used in the valuation include default and prepayment rates derived primarily from historical performance and relevant market data, adjusted as necessary based on the perceived credit risk of the underlying portfolio. In addition, discount rates based on estimates of the rates of return that investors would require when investing in similar credit card portfolios are applied to the individual freestanding derivatives.

The Convertible Preferred Stock Warrant Liability is valued using a Black-Scholes option pricing model. Refer to Note 13 for further details.

As PMI’s Borrower Loans, Loans Held for Sale, Notes, Convertible Preferred Stock Warrant Liability, Servicing Assets and Liability, Credit Card Derivative, Credit Card servicing obligation liability and loan trailing fee liability do not trade in an active market with readily observable prices, the Company uses significant unobservable inputs to measure the fair value of these assets and liabilities. Financial instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. These fair value estimates may also include observable, actively quoted components derived from external sources. As a result, gains and losses for assets and liabilities within the Level 3 category may include changes in fair value that were attributable to both observable and unobservable inputs. Prosper did not transfer any assets or liabilities in or out of Level 3 for the three months ended March 31, 2024 and 2023.

Significant Unobservable Inputs

The following tables present quantitative information about the ranges of significant unobservable inputs used for the Company’s Level 3 fair value measurements at March 31, 2024 and December 31, 2023:

	Range
Borrower Loans, Loans Held for Sale and Notes:	March 31, 2024	December 31, 2023
Discount rate	5.4% - 11.1%	5.4% - 8.1%
Default rate	2.9% - 24.3%	3.2% - 23.6%

	Range
Servicing Assets:	March 31, 2024	December 31, 2023
Discount rate	15.0% - 25.0%	15.0% - 25.0%
Default rate	2.5% - 24.4%	2.8% - 23.6%
Prepayment rate	6.2% - 30.5%	6.1% - 30.6%
Market servicing rate (1) (2)	0.633% - 0.842%	0.633% - 0.842%

(1) Servicing assets associated with loans enrolled in a relief program offered by the Company as of March 31, 2024 and December 31, 2023 were measured using a market servicing rate assumption of 84.2 basis points. This rate was estimated using a multiplier consistent with observable market rates for other loan types, applied to the base market servicing rate assumption.

(2) Excludes collection fees that would be passed on to a hypothetical third-party servicer. As of March 31, 2024 and December 31, 2023, the market rate for collection fees and non-sufficient fund fees was assumed to be 6 basis points and 5 basis points, respectively, for a total market servicing rate range of 69.3 - 90.2 basis points and 68.3 - 89.2 basis points, respectively.

	Range
Loan Trailing Fee Liability:	March 31, 2024	December 31, 2023
Discount rate	15.0% - 25.0%	15.0% - 25.0%
Default rate	2.5% - 24.4%	2.8% - 23.6%
Prepayment rate	6.2% - 30.5%	6.1% - 30.6%

Ranges of inputs are not applied to the Credit Card Derivative and Credit Card servicing obligation liability, as they are valued at the portfolio level. Refer below for a summary of the significant unobservable inputs associated with those Level 3 fair value measurements.

At March 31, 2024 and December 31, 2023, the discounted cash flow methodology used to estimate the Notes fair values used the same projected cash flows as the related Borrower Loans.

(1) Refer to Change in Estimate section below.

These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a variation in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects.

Change in Estimate

Effective March 31, 2024, the Company applied a single discount rate to all of the projected cash flows that comprise the Credit Card Derivative and Credit Card servicing obligation liability, in order to better align with how PMI believes a market participant would estimate the fair value of those cash flows. This single discount rate reflects the expected market rate of return from an investment in residual cash flows derived from a credit card portfolio. Previously, separate discount rates were applied to different cash flows reflecting assumptions around counterparty credit risk. The effect of this change in estimate increased the Credit Card Derivative by $7.3 million and reduced the Credit Card servicing obligation by $1.9 million as of March 31, 2024. Accordingly, it increased Total Net Revenue and Net Income by $9.2 million for the three months ended March 31, 2024.

9. Goodwill and Other Intangible Assets, Net

Goodwill 

Prosper’s goodwill balance of $36.4 million at December 31, 2023 did not change during the three months ended March 31, 2024. The Company recorded no goodwill impairment for the three months ended March 31, 2024 and 2023.

Other Intangible Assets 

The following table presents the detail of other intangible assets subject to amortization as of the following date (dollars in thousands):

	March 31, 2024

11. Debt

Term Loan

Credit Agreement

On November 14, 2022, the Company entered into a Credit Agreement with a third-party financial institution, which provides for a $75 million Term Loan maturing on November 14, 2026. Proceeds received from the Term Loan were net of an original issue discount and the Company also incurred approximately $0.4 million in debt issuance costs. Both the original issue discount and the debt issuance costs are being amortized over the life of the Term Loan to interest expense using the effective interest method.

Interest

32

Borrowings under the Term Loan accrue interest at the Secured Overnight Financing Rate (“SOFR”) plus 9.0% per annum. In addition, all borrowings under the Term Loan accrue payment-in-kind (“PIK”) interest at 2.0% per annum. Any accrued PIK interest that remains unpaid at the end of each month is added to the outstanding principal balance of the Term Loan.

Guarantees and Collateral

PMI’s obligations under the Term Loan are guaranteed by PHL and BillGuard. All obligations under the Credit Agreement are secured by a first priority, perfected lien on substantially all of the assets of PMI (subject to exclusions such as certain cash amounts and deposit accounts), PHL and BillGuard, as well as equity interests in all of PMI’s subsidiaries with the exception of PGT.

Covenants and Other Matters

The Credit Agreement contains a number of covenants that, among other things and subject to certain exceptions and thresholds, restrict PMI’s ability to incur certain new indebtedness; incur certain liens; sell or otherwise dispose of all or substantially all its assets; make loans, advances, and guarantees; and pay dividends or make other distributions on equity interests.

In addition, the Credit Agreement contains certain financial covenants with which the Company must remain in compliance as of the last business day of each month during the life of the Term Loan:

•a minimum tangible net worth

•a minimum net liquidity

•a maximum leverage ratio

•a minimum asset coverage ratio

The Company is in compliance with all covenants as of March 31, 2024, as well as applicable monthly periods for the quarter then ended.

The Credit Agreement also contains certain customary representations and warranties and affirmative covenants, and certain reporting obligations. In addition, the Term Loan lender will be permitted to accelerate all outstanding borrowings and exercise other specified remedies upon the occurrence of certain events of default (subject to certain grace periods and exceptions), which include, among other things, payment defaults, breaches of representations and warranties, covenant defaults, certain cross-defaults to other indebtedness, certain events of bankruptcy and insolvency, certain judgments and changes of control.

Prosper Warehouse Trust Agreements

Prosper’s consolidated warehouse VIEs, PWIT and PWIIT (together, the “Warehouse VIEs”), each entered into an agreement (together, the “Warehouse Agreements”) with certain lenders for committed revolving lines of credit (“Warehouse Lines”) during 2018 and 2019, respectively. In connection with the Warehouse Agreements, the Warehouse VIEs each entered into a security agreement with a bank as administrative agent and a national banking association as collateral trustee and paying agent. Proceeds under the Warehouse Lines could only be used to purchase certain unsecured consumer loans and related rights and documents from Prosper and to pay fees and expenses related to the Warehouse Lines. Both Warehouse VIEs are consolidated because Prosper is the primary beneficiary of the VIEs. The assets of the VIEs can be used only to settle obligations of the VIEs. Additionally, the creditors of the Warehouse Lines have no recourse to the general credit of Prosper. The loans held in the Warehouse VIEs are included in Loans Held for Sale, at Fair Value and Warehouse Lines are in Warehouse Lines in the condensed consolidated balance sheets.

Both Warehouse Agreements contained certain covenants including restrictions on each Warehouse VIE's ability to incur indebtedness, pledge assets, merge or consolidate and enter into certain affiliate transactions. Each Warehouse Agreement also required Prosper to maintain a minimum tangible net worth of $25 million, minimum net liquidity of $15 million and a maximum leverage ratio of 5:1. Tangible net worth is defined as the sum of (i) (A) Convertible Preferred Stock, (B) total Stockholders’ Deficit and (C) Convertible Preferred Stock Warrant Liability, less the sum of (ii) (A) goodwill and (B) intangible assets. Net liquidity is defined as the sum of cash, cash equivalents and Available for Sale Investments. The leverage ratio is defined as the ratio of total consolidated indebtedness other than non-recourse securitization indebtedness, non-recourse or limited recourse warehouse indebtedness and borrower dependent notes, to tangible net worth. Through the dates of termination of each Warehouse Line, as discussed below, the Company was not in violation of any of these covenants.

PWIT Warehouse Line

33

On January 19, 2018, through PWIT, Prosper entered into a Warehouse Agreement for a Warehouse Line with a national banking association for a committed line of credit of $100 million. The PWIT Warehouse Agreement was subsequently amended in June 2018, June 2019, and May 2021, the cumulative impact of which was to increase the committed line of credit to $200 million, adjust the interest rate and unused commitment fee, expand the eligibility criteria for unsecured consumer loans that could be financed through the PWIT Warehouse Line and extend the term of the Warehouse Agreement.

On May 5, 2023, PMI further amended its PWIT Warehouse Line (“PWIT 2023 Extension”). The PWIT 2023 Extension increased the maximum borrowing amount from $200 million to $244 million, consisting of a $200 million Class A loan with the existing PWIT Warehouse Line national banking association and a $44 million Class B loan with an asset manager. Under the PWIT 2023 Extension, the total advance rate was 91.5% and proceeds of loans purchased through the PWIT Warehouse Line could be borrowed, repaid and reborrowed until the earlier of June 20, 2024 or the occurrence of any accelerated amortization event or event of default. Repayment on any outstanding proceeds would be made over a 12-month period ending June 20, 2025, excluding the occurrence of any accelerated amortization event or event of default. Under the PWIT 2023 Extension, the Class A loan bore interest at a rate of one-month SOFR, plus a spread of 2.75% per annum, while the Class B loan bore interest at a rate of one-month SOFR, plus a spread of 8.50% per annum. Additionally, until June 20, 2024, both loans bore a daily unused commitment fee of 0.50% per annum on the undrawn portion available under each respective loan.

In the fourth quarter of 2023, a loan performance ratio under the Warehouse Agreement was exceeded which resulted in the PWIT Warehouse Line entering accelerated amortization. While in accelerated amortization, all loan collections were applied against the outstanding balance of the PWIT Warehouse Line, and the Company was unable to utilize the undrawn portion. In addition, there was a 1% per annum step-up fee on the outstanding balance. On January 22, 2024, the Company executed an amendment to the PWIT Warehouse Agreement, under which previous breaches of loan performance ratios were waived, the loan performance ratios were revised going forward, and the step-up fee was waived until June 30, 2024. Additionally, the advance rate under the PWIT Warehouse Line was to gradually decrease by 1% on a monthly basis through June 2024, until it was reduced to 86.5%.

In conjunction with the PMIT 2024-1 securitization (see Note 7, Securitizations), the entire portfolio of Loans Held for Sale in the PWIT Warehouse Line, with an unpaid principal balance of $142.5 million as of March 28, 2024, was transferred to either the PMIT 2024-1 Transaction or PFL, as follows: $138.0 million of those Borrower Loans were contributed into the securitization trust through a depositor, and the remaining $4.5 million consisted of loans ineligible for securitization and were transferred to PFL through an equity contribution. Proceeds from the sale of these loans were used to pay down the outstanding principal and interest on the PWIT Warehouse Line of $130.4 million, and the PWIT Warehouse line was terminated at that time. Remaining proceeds, net of transaction expenses, following the securitization transaction were transferred to PMI. As a result of the termination of the PWIT Warehouse Line, deferred and unamortized debt issuance costs of $0.7 million were immediately amortized into interest expense.

Prosper maintained a swaption to limit the Company's exposure to increases in SOFR on up to $185.0 million of borrowings under the PWIT Warehouse Line. The swaption was recorded on the consolidated balance sheets at fair value in “Prepaids and Other Assets.” Any changes in the fair value were recorded in the “Change in Fair Value of Financial Instruments” on the condensed consolidated statement of operations. The swaption was terminated on March 28, 2024 upon repayment and termination of the PWIT Warehouse Line in conjunction with the PMIT 2024-1 securitization. The change in fair value of the swaption was immaterial for the three months ended March 31, 2024 and a loss of $0.5 million for the corresponding period in 2023.

PWIIT Warehouse Line

On March 28, 2019, through PWIIT, Prosper entered into a second Warehouse Agreement for a $300 million Warehouse Line with a national banking association different than that of PWIT. Subsequently on March 4, 2021, PMI extended its $300 million PWIIT Warehouse Line (“PWIIT 2021 Extension”). The PWIIT 2021 Extension consisted of a $230 million Class A loan with the existing PWIIT Warehouse Line national banking association and a $70 million Class B loan with an asset manager. On February 10, 2023, PMI again extended its PWIIT Warehouse Line (“PWIIT 2023 Extension”). The PWIIT 2023 Extension increased the maximum borrowing amount from $300 million to $450 million, consisting of a $400 million Class A loan with the existing PWIIT Warehouse Line national banking association and a $50 million Class B loan with the existing asset manager. In May 2023, the Company further amended the PWIIT Warehouse Line, which included replacing the existing Class B lender with another third-party asset manager and lowering the spread on Class B borrowings. In July 2023, the PWIIT Warehouse Line was further amended, decreasing the maximum borrowing amount from $450 million to $300 million, consisting of a $265 million Class A loan and a $35 million Class B loan. The Class A loan bore interest at a per annum rate of the national banking association's asset-backed commercial paper rate, plus a spread of 2.85%, while the Class B loan bore interest a per annum rate of adjusted one-month SOFR, plus a spread of 8.75%.

34

In conjunction with the PMIT 2023-1 securitization (see Note 7, Securitizations), the entire portfolio of Loans Held for Sale in the PWIIT Warehouse Line, with an unpaid principal balance of $273.8 million as of September 25, 2023, was transferred to either the PMIT 2023-1 securitization or PFL, as follows: $266.1 million of those Borrower Loans were contributed into the securitization trust through a depositor, and the remaining $7.7 million consisted of loans ineligible for securitization and were transferred to PFL through an equity contribution. Proceeds from the sale of these loans were used to pay down the outstanding principal and interest on the PWIIT Warehouse Line of $224.0 million, and the PWIIT Warehouse line was terminated at that time. Remaining proceeds, net of transaction expenses, following the securitization transaction were transferred to PMI. As a result of the termination of the PWIIT Warehouse Line, deferred and unamortized debt issuance costs of $1.9 million were immediately amortized into interest expense.

12. Net Income (Loss) Per Share

PMI computes its net income (loss) per share in accordance with ASC Topic 260, Earnings Per Share (“ASC Topic 260”). Under ASC Topic 260, basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities.

PMI’s net income (loss) per share is calculated using the two-class method in accordance with ASC Topic 260. The two-class method allocates earnings that otherwise would have been available to common shareholders to holders of participating securities. Management considers all series of our Convertible Preferred Stock to be participating securities due to their rights to participate in dividends with Common Stock. As such, earnings allocated to these participating securities, which include participation rights in undistributed earnings, are subtracted from net income to determine total undistributed earnings to be allocated to common stockholders.

All participating securities are excluded from basic weighted-average common shares outstanding. Prior to any conversion to common shares, each series of Prosper’s Convertible Preferred Stock is entitled to participate on an if-converted basis in distributions of earnings, when and if declared by the board of directors, that are made to common stockholders and consequently, these shares were considered participating securities. During the three months ended March 31, 2024 and 2023, certain shares issued as a result of the early exercise of stock options which are subject to a repurchase right by PMI were entitled to receive non-forfeitable dividends during the vesting period and consequently, are considered participating securities.

Basic and diluted net income (loss) per share were calculated as follows for the periods presented (in thousands, except share and per share amounts):

	Three Months Ended March 31,

13. Convertible Preferred Stock, Convertible Preferred Stock Warrant Liability and Common Stock

Convertible Preferred Stock and Warrants

Under PMI’s amended and restated certificate of incorporation, preferred stock is issuable in series, and the Board of Directors is authorized to determine the rights, preferences, and terms of each series.

On July 13, 2020, the Company established Prosper Grantor Trust (“PGT”), a revocable grantor trust administered by an independent trustee, with the intention of contributing assets to PGT for the benefit of PMI employees in the event of a change in control through an Eligible Employee Retention Plan. PGT was determined to be a VIE and PMI was determined to be its primary beneficiary due to the fact that the Company, through its role as the grantor, has both (a) the power to direct the activities that most significantly affect the VIE’s economic performance, including its funding decisions and investment strategy, and (b) the obligation to absorb losses that could be potentially significant to the economic performance of the VIE by virtue of the Company’s requirement to fund PGT in the event that it is unable to meet its obligations to PMI’s employees. PMI also maintains a contingent call liability on PGT’s assets in the event of a bankruptcy. As a result, PGT is fully consolidated into PMI’s consolidated financial statements.

On July 21, 2020, PGT entered into a Stock Transfer Agreement with a PMI investor to purchase 34,670,420 shares of Series A Convertible Preferred Stock and 16,577,495 shares of Series B Convertible Preferred Stock for nominal consideration. Upon execution of the Stock Transfer Agreement, these shares were purchased by a consolidated VIE of the Company, and thus the difference between the fair value of the repurchased stock and the purchase price is included in Convertible Preferred Stock

36

Held by Consolidated VIE on PMI’s accompanying condensed consolidated balance sheets. These shares remain outstanding for legal purposes and retain their voting rights, but are excluded from the earnings per share calculation.

The number of authorized, issued and outstanding shares, their par value and liquidation preference for each series of convertible preferred stock as of March 31, 2024 are disclosed in the table below (amounts in thousands except share and par value amounts):

Convertible Preferred Stock	Par Value		Authorized Shares	Outstanding and Issued Shares		Liquidation Preference, Outstanding Shares
Series A	$	0.01	68,558,220	66,428,185	*	$	19,160

* Series A and Series B Convertible Preferred Stock totals are inclusive of 34,670,420 and 16,577,495 shares, respectively, held by PGT, a consolidated VIE.

Dividends

Dividends on shares of the Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F and Series G convertible preferred stock are payable only when, as, and if declared by the Board of Directors. No dividends will be paid with respect to the common stock until any declared dividends on the Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, and Series G convertible preferred stock have been paid or set aside for payment to the Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, and Series G convertible preferred stockholders. After payment of any such dividends, any additional dividends or distributions will be distributed among all holders of common stock and preferred stock in proportion to the number of shares of common stock that would be held by each such holder if all shares of preferred stock were converted to common stock at the then-effective conversion rate. The Series A-1 convertible preferred shares have no dividend rights. To date, no dividends have been declared on any of PMI’s preferred stock or common stock.

Conversion

Under the terms of PMI’s amended and restated certificate of incorporation, the holders of preferred stock have the right to convert such preferred stock into common stock at any time. In addition, all preferred stock automatically converts into common stock (i) immediately prior to the closing of an initial public offering that values Prosper at least at $2 billion and that results in aggregate proceeds to Prosper of at least $100 million or (ii) upon a written request from the holders of at least 60% of the voting power of the outstanding preferred stock (on an as-converted basis), provided that (i) the Series A-1 convertible preferred stock shall not be converted without at least 14% of the voting power of the outstanding Series A-1 convertible preferred stock; (ii) the Series D shall not be converted without at least 60% of the voting power of the outstanding Series D; (iii) the Series E-1 and Series E-2 shall not be converted without at least 60% of the voting power of the outstanding Series E-1 and Series E-2, voting together as a single class; (iv) the Series F shall not be converted without at least 60% of the voting power of the outstanding Series F, and (v) the shares of Series G Preferred Stock will not be automatically converted unless the holders of at least 60% of the outstanding shares of Series G Preferred Stock approve such conversion. In addition, if a holder of the Series A convertible preferred stock has converted any of the Series A convertible preferred stock, then all of such holder’s shares of Series A-1 convertible preferred stock also will be converted upon a liquidation event (as defined under the certificate of incorporation). In lieu of any fractional shares of common stock to which a holder would otherwise be entitled, PMI shall pay such holder cash in an amount equal to the fair market value of such fractional shares, as determined by its Board of Directors. At present, each of the Series A, Series B, Series C, Series D, Series E-1, Series E-2, and Series F convertible preferred stock converts into PMI common stock at a 1:1 ratio. The Series A-1 convertible preferred stock converts into common stock at a 1,000,000:1 ratio and the Series G convertible preferred stock converts into common stock at a 1:1.36 ratio. The Series G convertible preferred stock conversion ratio reflects the Series G true-up that occurred at end of the vesting period for the Series E-2 and Series F Preferred Stock warrants.

37

For the Series G true-up, the conversion price of the Series G Convertible Preferred Stock was reduced to a number equal to the Series G Preferred Stock original issuance price, divided by the quotient obtained by dividing the Series G true-up amount by the total number of Series G Preferred Stock issued as of the Series G closing date. The Series G true-up amount means the aggregate number of shares of Series G Preferred Stock that would have been issued to the purchasers of the Series G Preferred Stock on the Series G closing date, if warrants to purchase shares of Series E-2 Preferred Stock or Series F Preferred Stock that were exercisable or exercised as of the true-up time (end of vesting period) had been exercisable or exercised as of such Series G closing date.

Liquidation Rights

PMI’s convertible preferred stock has been classified as temporary equity on the condensed consolidated balance sheets. The preferred stock is not redeemable; however, in the event of a voluntary or involuntary liquidation, dissolution, change in control or winding up of PMI, holders of the convertible preferred stock may have the right to receive its liquidation preference under the terms of PMI’s certificate of incorporation.

Each holder of Series E-1, Series E-2, and Series F convertible preferred stock is entitled to receive prior and in preference to any distribution of proceeds from a liquidation event (as defined under the certificate of incorporation) to the holders of Series A, Series B, Series C, Series D, Series G and Series A-1 convertible preferred stock or common stock, an amount per share for (i) each share of Series E-1 convertible preferred stock equal to the sum of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share, (ii) each share of Series E-2 convertible preferred stock equal to the sum of two-thirds the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share, and (iii) each share of Series F convertible preferred stock equal to the sum of two-thirds of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share.

After the payment or setting aside for payment to the holders of Series E-1, Series E-2, and Series F convertible preferred stock, each holder of Series A, Series B, Series C and Series D, Series E-2, Series F, and Series G convertible preferred stock is entitled to receive, on a pari passu basis, prior to and in preference to any distribution of proceeds from a liquidation event (as defined under the certificate of incorporation) to the holders of Series A-1 convertible preferred stock or common stock, (i) an amount per share for each share of Series E-2 and Series F convertible preferred stock equal to the sum of one-third of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share, and (ii) an amount per share for each share of Series A, Series B, Series C, Series D and Series G convertible preferred stock equal to the sum of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share.

After the payment or setting aside for payment to the holders of Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, and Series G convertible preferred stock, the holders of Series A-1 convertible preferred stock are entitled to receive, prior and in preference to any distribution of proceeds to the holders of common stock, an amount per share for each such share of Series A-1 convertible preferred stock equal to the sum of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share.

After the payment or setting aside for payment to the holders of Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, Series G, and Series A-1 convertible preferred stock, the entire remaining proceeds legally available for distribution will be distributed pro rata to the holders of Series A convertible preferred stock and common stock in proportion to the number of shares of common stock held by them assuming the Series A convertible preferred stock has been converted into shares of common stock at the then effective conversion rate, provided that the maximum aggregate amount per share of Series A convertible preferred stock which the holders of Series A convertible preferred stock shall be entitled to receive is three times the original issue price for the Series A convertible preferred stock.

At present, the liquidation preferences are equal to $0.29 per share for the Series A convertible preferred stock, $2.00 per share for the Series A-1 convertible preferred stock, $0.60 per share for the Series B convertible preferred stock, $2.87 per share for the Series C convertible preferred stock, $6.91 per share for the Series D convertible preferred stock, $0.84 per share for the Series E-1 convertible preferred stock, $0.84 per share for the Series E-2 convertible preferred stock, $0.84 per share for the Series F convertible preferred stock and $1.34 per share for the Series G convertible preferred stock.

Voting

Each holder of shares of convertible preferred stock is entitled to the number of votes equal to the number of shares of common stock into which such shares of convertible preferred stock could be converted and has voting rights and powers equal to the voting rights and powers of the common stock. The holders of convertible preferred stock and the holders of common stock vote together as a single class (except with respect to certain matters that require separate votes or as required by law), and are entitled to notice of any stockholders’ meeting in accordance with the Bylaws of PMI.

Convertible Preferred Stock Warrant Liability

Series E-1 Warrants

In connection with the Settlement and Release Agreement dated November 17, 2016 among PMI, its wholly owned subsidiary Prosper Funding LLC (“PFL”) and Colchis, on December 16, 2016, PMI issued the First Series E-1 Warrant for 20,267,135 shares of Series E-1 convertible preferred stock. The Second Series E-1 Warrant for an additional 15,277,006 shares of Series E-1 convertible preferred stock was granted on the signing of the Consortium Purchase Agreement (as described in Note 13 of PMI’s 10-K for the year ended December 31, 2023) on February 27, 2017. The Series E-1 warrants have an exercise price of $0.01 per share and expire ten years from the date of issuance. For the three months ended March 31, 2024 and 2023, Prosper recognized $4.6 million and $0.7 million of income, respectively, from the re-measurement of the fair value of the warrants. The income or expense resulted from the remeasurement of the fair value of the warrants is recorded in Change in Fair Value of Convertible Preferred Stock Warrants on the condensed consolidated statements of operations.

To determine the fair value of the Series E-1 Warrants, the Company first determined the value of a share of Series E-1 Convertible Preferred Stock. To determine the fair value of the Convertible Preferred Stock, the Company first derived the business enterprise value (“BEV”) of the Company using a variety of valuation methods, including discounted cash flow models and market based methods, as deemed appropriate under the circumstances applicable at the valuation date. Once the Company determined an estimated BEV, the option pricing method (“OPM”) was used to allocate the BEV to the various classes of our equity, including our preferred stock. The concluded per share value for the Series E-1 Convertible Preferred Stock was utilized as an input to the Black-Scholes option pricing model.

The Company determined the fair value of the outstanding Series E-1 preferred stock warrants utilizing the following assumptions as of the following dates:

	March 31, 2024		December 31, 2023
Volatility	65.0	%	66.0	%
Risk-free interest rate	4.40	%	4.10	%
Expected term (in years)	2.75		2.75
Dividend yield	—	%	—	%

The above assumptions were determined as follows:

Volatility: The volatility is derived from historical volatilities of several unrelated publicly listed peer companies over a period approximately equal to the term of the warrant as the Company has limited information on the volatility of its preferred stock since there is currently no trading history. When making the selections of industry peer companies to be used in the volatility calculation, the Company considered the size, operational, and economic similarities to the Company’s principal business operations.

Risk-Free Interest Rate: The risk-free interest rate is based on the U.S. Treasury yield in effect as of March 31, 2024, and for zero coupon U.S. Treasury notes with maturities approximately equal to the term of the warrant.

Expected Term: The expected term is the period of time for which the warrants are expected to be outstanding.

Dividend Yield: The expected dividend assumption is based on the Company’s current expectations about the Company’s anticipated dividend policy.

Series F Warrants

In connection with the Consortium Purchase Agreement on February 27, 2017, PMI issued warrants to purchase up to 177,720,706 shares of PMI's Series F convertible preferred stock at $0.01 per share. The warrants expire ten years from the date of issuance. For the three months ended March 31, 2024 and 2023, Prosper recognized $23.1 million and $3.6 million of income, respectively, from the re-measurement of the fair value of the warrants. The income or expense resulting from changes in the fair value of the warrant is recorded through Change in Fair Value of Convertible Preferred Stock Warrants on the condensed consolidated statements of operations.

To determine the fair value of the Series F Warrants, the Company first determined the value of a share of Series F Convertible Preferred Stock. To determine the fair value of the Convertible Preferred Stock, the Company first derived the BEV using valuation methods, including a combination of methods, as deemed appropriate under the circumstances applicable at the valuation date. Once the Company determined an estimated BEV, the OPM was used to allocate the BEV to the various classes

39

of Prosper's equity, including our preferred stock. The concluded per share value for the Series F Convertible Preferred Stock warrants utilized the Black-Scholes option pricing model.

The Company determined the fair value of the outstanding Series F Warrants utilizing the following assumptions as of the following dates:

	March 31, 2024		December 31, 2023
Volatility	65.0	%	66.0	%
Risk-free interest rate	4.40	%	4.10	%
Expected term (in years)	2.75		2.75
Dividend yield	—	%	—	%

The above assumptions were determined using the same criteria described above for the Series E-1 Warrants.

The combined activity of the Convertible Preferred Stock Warrant Liability for the three months ended March 31, 2024 and 2023 are presented in Note 8, Fair Value of Assets and Liabilities. Starting with the Series E and F Warrant valuations prepared as of September 30, 2023, due to a change in methodology, the Company removed the discount for lack of marketability that was previously applied to the Black-Scholes option pricing valuation. If a discount for lack of marketability was applied to the valuation as of March 31, 2024, it would reduce the Convertible Preferred Stock Warrant Liability by approximately $36.4 million.

Common Stock

PMI, through its Amended and Restated Certificate of Incorporation, is the sole issuer of common stock and related options, RSUs and warrants. On February 16, 2016, PMI amended and restated its Certificate of Incorporation to, among other things, effect a 5-for-1 forward stock split. On September 20, 2017, PMI further amended its Amended and Restated Certificate of Incorporation to increase the number of shares of common stock authorized for issuance. The total number of shares of stock which PMI has the authority to issue is 1,069,760,848, consisting of 625,000,000 shares of common stock, $0.01 par value per share, and 444,760,848 shares of preferred stock, $0.01 par value per share. As described above, the Company repurchased 2,196,665 shares of Common Stock on December 23, 2019. As of March 31, 2024, 78,112,888 shares of common stock were issued and 77,176,953 shares of common stock were outstanding. As of December 31, 2023, 77,861,329 shares of common stock were issued and 76,925,394 shares of common stock were outstanding. Each holder of common stock is entitled to one vote for each share of common stock held.

Common Stock Issued upon Exercise of Stock Options

For the three months ended March 31, 2024, PMI issued 251,559 shares of common stock upon the exercise of vested options for cash proceeds of $8 thousand.

14. Stock-Based Compensation

PMI grants equity awards primarily through its Amended and Restated 2005 Stock Option Plan (the “2005 Plan”), which was approved as amended and restated by its stockholders on December 1, 2010; and its 2015 Equity Incentive Plan, which was approved by its stockholders on April 7, 2015 and subsequently amended by an Amendment No. 1, Amendment No. 2 and Amendment No. 3, which were approved by PMI's stockholders effective as of February 15, 2016, May 31, 2016, and September 5, 2018 respectively (as amended, the “2015 Plan”). In March 2015, the 2005 Plan expired, except that any awards granted under the 2005 Plan prior to its expiration remain in effect pursuant to their terms.

Stock Option Activity

Stock option activity under the 2005 Plan and 2015 Plan is summarized for the three months ended March 31, 2024 below:

	Options Issued and Outstanding	Weighted Average Exercise Price
Balance as of January 1, 2024	82,113,271	$	0.15
Options issued	3,854,515	$	0.40
Options exercised	(251,559)	$	0.03
Options forfeited	(2,382,025)	$	0.18
Options expired	(15,000)	$	0.02
Balance as of March 31, 2024	83,319,202	$	0.16
Options vested and expected to vest as of March 31, 2024	76,528,968	$	0.16
Options vested and exercisable as of March 31, 2024	60,750,156	$	0.09

Other Information Regarding Stock Options

The weighted-average remaining contractual term for options outstanding as of March 31, 2024 is 5.65 years.

The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires PMI to make assumptions and judgments about the variables used in the calculation, including the fair value of PMI’s common stock, the expected term (the period of time that the options granted are expected to be outstanding), the volatility of PMI’s common stock, a risk-free interest rate, and expected dividends. Given the absence of a publicly traded market, the Company considered numerous objective and subjective factors to determine the fair value of PMI’s common stock at each grant date. These factors included, but were not limited to: (i) contemporaneous valuations of common stock performed by unrelated third-party specialists, (ii) the prices for PMI’s preferred stock sold to outside investors, (iii) the rights, preferences and privileges of PMI’s preferred stock relative to PMI’s common stock, (iv) the lack of marketability of PMI’s common stock, (v) developments in the business, (vi) secondary transactions of PMI’s common and preferred shares, and (vii) the likelihood of achieving a liquidity event, such as an initial public offering or a merger or acquisition of Prosper, given prevailing market conditions. As PMI’s stock is not publicly traded, volatility for stock options is based on an average of the historical volatilities of the common stock of several entities with characteristics similar to those of PMI. The expected term assumptions were determined based on the vesting terms, exercise terms and contractual lives of the options using the simplified method. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. PMI uses an expected dividend yield of zero as it does not anticipate paying any dividends in the foreseeable future.

PMI also estimates forfeitures of unvested stock options. Expected forfeitures are based on the Company’s historical experience. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded for options that do not vest.

The fair value of PMI’s stock option awards granted during the three months ended March 31, 2024 and 2023 was estimated at the date of grant using the Black-Scholes model with the following average assumptions:

	Three Months Ended March 31,
	2024		2023
Volatility of common stock	66.30	%	66.69	%
Risk-free interest rate	4.17	%	3.67	%
Expected life (in years)	6.0 years		6.0 years
Dividend yield	—	%	—	%

Restricted Stock Unit Activity

In previous years, PMI granted RSUs to certain employees that are subject to three-year or four-year vesting terms and the occurrence of a liquidity event.

41

The following table summarizes the number of PMI’s RSU activity for three months ended March 31, 2024:

	Number of Shares	Weighted-Average Grant Date Fair Value
Unvested at January 1, 2024	2,574,633	$	1.03
Forfeited	(9,500)	$	2.18
Unvested at March 31, 2024	2,565,133	$	1.02

Share Based Compensation

The following table presents the amount of stock-based compensation related to stock-based awards granted to employees recognized in Prosper’s condensed consolidated statements of operations for the periods presented (in thousands):

	Three Months Ended March 31,
	2024		2023
Origination and servicing	$	19	$	21
Sales and marketing	113		36
General and administrative	260		311
Total stock-based compensation	$	392	$	368

As of March 31, 2024, the unamortized stock-based compensation expense, adjusted for forfeiture estimates, related to unvested stock-based awards was approximately $3.0 million, which will be recognized over a remaining weighted-average vesting period of approximately 2.6 years.

15. Income Taxes

For the three months ended March 31, 2024 and 2023, PMI recognized $26 thousand and $70 thousand of income tax expense, respectively. The income tax expense relates to state income tax expense and the amortization of tax deductible goodwill which gives rise to an indefinite-lived deferred tax liability. No other income tax expense or benefit was recorded for the three month periods ended March 31, 2024 and 2023 due to a full valuation allowance recorded against the Company’s deferred tax assets.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize our existing deferred tax assets. On the basis of this evaluation, it is not more likely than not that our deferred tax assets will be realized and therefore a full valuation allowance has been recorded.

16. Leases

Prosper has operating leases for corporate offices and a data center. These leases have remaining lease terms of less than one year to approximately five years. Some of the lease agreements include options to extend the lease term for up to an additional five years. Rental expense under operating lease arrangements was $1.0 million and $1.1 million for the three months ended March 31, 2024 and 2023. Additionally, Prosper subleases certain leased office space to third parties when it determines there is excess leased capacity. Sublease income from operating lease arrangements was $0.1 million and $0.2 million for the three months ended March 31, 2024 and 2023.

Operating Lease Right-of-Use (“ROU”) Assets

The following table summarizes the operating lease right-of-use assets as of March 31, 2024, which are included in “Property and Equipment, Net” on the condensed consolidated balance sheets.

	March 31, 2024
	Gross Carrying Value		Accumulated Amortization		Net Carrying Value
ROU Assets - Office buildings	$	22,690	$	12,347	$	10,343

42

No impairment charge was identified for the three months ended March 31, 2024 and 2023.

In March 2024, the Company entered into an amendment to its Phoenix office lease, the most prominent impact of which was to extend the lease term for an additional period through October 2029. As a result of this lease modification, the Company recorded additional ROU operating lease assets and liabilities of $0.3 million.

Lease Liabilities

Future maturities of operating lease liabilities as of March 31, 2024 were as follows (in thousands). The present value of the future minimum lease payments represents our operating lease liabilities as of March 31, 2024 and are included in "Other Liabilities" on the condensed consolidated balance sheets.

	March 31, 2024
Remainder of 2024	$	3,181
2025	4,247
2026	4,648

Thereafter	411
Total future minimum lease payments	$	18,269
Less imputed interest	(4,216)
Present value of future minimum lease payments	$	14,053

Because the rate implicit in each lease is not readily determinable, we use our incremental borrowing rate to determine the present value of the lease payments. Other information related to leases was as follows (dollars in thousands):

Weighted average remaining lease term (in years)	4.07 years
Weighted average discount rate	12.50	%

17. Commitments and Contingencies

In the normal course of its operations, Prosper becomes involved in various legal actions. Prosper maintains provisions it considers to be adequate for such actions. Prosper does not believe it is probable that the ultimate liability, if any, arising out of any such matters will have a material effect on Prosper's financial condition, results of operations or cash flows.

Operating Commitments

PMI, along with PFL, and WebBank have entered into: (i) an Asset Sale Agreement, dated July 1, 2016, between PFL and WebBank, as most recently amended by a Seventh Amendment dated February 28, 2024 (as amended, the “Sale Agreement”); (ii) the Marketing Agreement, dated July 1, 2016, between PMI and WebBank, as most recently amended by a Seventh Amendment dated February 28, 2024 (as amended, the “Marketing Agreement”); and (iii) the Stand By Purchase Agreement, dated July 1, 2016, between PMI and WebBank, as most recently amended by a Fourth Amendment dated February 28, 2024 (as amended, the “Purchase Agreement” and, collectively with the Sale Agreement and the Marketing Agreement, the “Origination and Sale Agreements”). Under the Origination and Sale Agreements, all Borrower Loans originated through the marketplace are made by WebBank under its bank charter.

The Origination and Sale Agreements contain terms through February 1, 2027. Prosper is required, under the Origination and Sale Agreements, to maintain certain collateral requirements. In addition, pursuant to the Marketing Agreement, the marketing fee that Prosper receives in connection with the origination of each loan is partially reduced by an amount (the “Designated Amount”) calculated as a percentage of the principal amount of such loan based on the aggregate principal amount of loans originated for the applicable month. To the extent the aggregate Designated Amount for all loans originated during any month is less than $100,000 through February 1, 2027, Prosper is required to pay WebBank an amount

43

equal to such deficiency. Accordingly, the minimum fee is $0.9 million for the remaining nine months of 2024, $1.2 million in 2025, $1.2 million in 2026 and $0.1 million in 2027.

Additionally, under the Origination and Sale Agreements, Prosper is required to maintain a minimum net liquidity of $15.0 million at all times during the term of the agreement. Net liquidity is defined as the sum of Cash, Cash Equivalents and Available for Sale Investments. Violation of this covenant can result in termination of the contract with WebBank. As of March 31, 2024, the Company was in compliance with the covenant.

Transaction Fee Refunds

Prosper assumes WebBank’s liability under Utah law to refund the pro-rated amount of any transaction fees collected in excess of 5%, in the event the underlying borrower prepays the loan before full maturity. The Company has accrued $3.9 million and $1.6 million as of March 31, 2024 and December 31, 2023, respectively, related to anticipated future refunds under this obligation.

Loan Purchase Commitments

Prosper entered into an agreement with WebBank to purchase $15.0 million of Borrower Loans that WebBank originated during the last two business days of the quarter ended March 31, 2024. Prosper will purchase these Borrower Loans within the first two business days of the quarter ending June 30, 2024.

Repurchase Obligation    

Under the terms of the loan purchase agreements between Prosper and investors that participate in the Whole Loan Channel, Prosper may, in certain circumstances, become obligated to repurchase a Borrower Loan from an investor. Generally, these circumstances include the occurrence of verifiable identity theft, the failure to properly follow personal loan listing or bidding protocols or a violation of the applicable federal, state or local lending laws. Prosper recognizes a liability at fair value for the repurchase obligation when the Borrower Loans are sold. The fair value of the repurchase obligation is estimated based on historical experience. Repurchased Borrower Loans associated with violations of federal, state or local lending laws or verifiable identity theft are written off at the time of repurchase. The maximum potential amount of future payments associated with this obligation is the outstanding balances of the Borrower Loans issued to third parties through the Whole Loan Channel, which at March 31, 2024 is $3.1 billion. Prosper has accrued $0.4 million and $0.5 million as of March 31, 2024 and December 31, 2023, respectively, in regard to this obligation.

Under the terms of the indenture and investor registration agreement, Prosper may, in certain circumstances, become obligated to either repurchase a Note or indemnify the investor for any losses resulting from nonpayment of a Note purchased in the Retail Channel. The decision to repurchase or indemnify is in Prosper’s sole discretion. These circumstances include, but are not limited to, the occurrence of verifiable identity theft, a technical error in the automated bidding tools which results in the purchase of a Note that does not match the investor’s investment criteria, or situations in which a personal loan listing includes a Prosper Rating that is different from the Prosper Rating that should have appeared in the listing for the corresponding Borrower Loan because either PFL inaccurately input data into, or inaccurately applied, the formula for determining the Prosper Rating and, as a result, the interest of the investor is materially and adversely affected. During the three months ended March 31, 2024 the Company repurchased $0.1 million of Notes under these circumstances, and has agreed to indemnify additional Notes with an unpaid principal balance of $0.7 million as of March 31, 2024.

Regulatory Contingencies

Prosper accrues for contingencies when a loss from such contingencies is probable and the amount of loss can be reasonably estimated. In determining whether a loss is probable and if it is possible to quantify the amount of the estimated loss, Prosper reviews and evaluates its litigation and regulatory matters on at least a quarterly basis in light of potentially relevant factual and legal developments. If Prosper determines that an unfavorable outcome is not probable or that the amount of a loss cannot be reasonably estimated, Prosper does not accrue for a potential litigation loss. If an unfavorable outcome is probable and Prosper can estimate a range of outcomes, an amount is recorded which management considers to be the best estimate within the range of potential losses that are both probable and estimable; however, if management cannot quantify the amount of the estimated loss, then the low end of the range of the potential losses is recorded.

44

West Virginia Matter

In February 2020, Prosper received a proposed Assurance of Discontinuance (an “AOD”) from the Attorney General of the State of West Virginia (the “WV Attorney General”) requesting that, without in any way admitting that any of its prior practices were in violation of the West Virginia Consumer Credit and Protection Act (the “Consumer Act”), Prosper agree to certain terms and conditions regarding its past and potential future conduct of its business with respect to customers in West Virginia, including a release by the WV Attorney General of any claims it may have related to the matters identified in the AOD.

We cannot predict the outcome of the matter and any potential fines or penalties, if any, that may arise from the matter. Further, we are unable to estimate a range of outcomes and as a result no accrual has been made.

No loans have been originated through the Prosper platform to West Virginians since June 2016 and the final loan originated through the Prosper platform to a borrower in West Virginia was repaid in October 2021.

18. Related Parties

Since Prosper’s inception, it has engaged in various transactions with its directors, executive officers, and holders of more than 10% of its voting securities, and immediate family members and other affiliates of its directors, executive officers, and 10% stockholders. Prosper believes that all of the transactions described below were made on terms no less favorable to Prosper than could have been obtained from unaffiliated third parties.

Prosper’s executive officers, directors who are not executive officers, and certain affiliates participate in its marketplace by placing bids and purchasing Notes. The aggregate amount of the Notes purchased and the income earned by parties deemed to be affiliates and related parties of Prosper for the three months ended March 31, 2024 and 2023, as well as the Notes outstanding as of March 31, 2024 and December 31, 2023 are summarized below (in thousands):

	Aggregate Amount of Notes Purchased the Three Months Ended March 31,				Interest Earned on Notes the Three Months Ended March 31,

19. Significant Concentrations

Prosper is dependent on third-party funding sources such as banks, asset managers, investment funds and Warehouse Lines to provide the funds to allow WebBank to originate Borrower Loans that the third-party funding sources will later purchase. Of all Borrower Loans originated in the three months ended March 31, 2024, five individual third parties purchased 31.3%, 19.3%, 12.1%, 10.3% and 10.3% of all Borrower Loans originated. There were no purchases of such loans by the Company’s VIEs during the three months ended March 31, 2024. For the three months ended March 31, 2023, individual third parties purchased 11.1% and 10.2% of all Borrower Loans originated, and the Company’s Warehouse VIEs purchased 20.0% of such loans.

Prosper receives all of its personal loan transaction fee revenue from WebBank. Prosper earns a transaction fee from WebBank for its services in facilitating originations of Borrower Loans issued by WebBank. The rate of the transaction fee for each individual Borrower Loan is based on the term and credit grade of the Borrower Loan. Starting in the fourth quarter of

45

2023, the Company raised its transaction fee cap from 5.0% to 7.99% for certain newly originated loans. No individual borrower or investor accounted for 10% or more of consolidated net revenue for any of the periods presented.

46

20. Segments

Starting with the fourth quarter of 2022, the Company realigned its reportable and operating segments to better reflect the nature and materiality of its product offerings. As a result of these changes, the Company now has three reportable and operating segments: Personal Loan, Home Equity and Credit Card.

The Company’s Chief Executive Officer, who serves as the chief operating decision maker (“CODM”) evaluates the financial performance of the Company’s segments based upon segment revenues, as well as segment Adjusted Net Revenue and segment Adjusted EBITDA, both non-GAAP profitability measures. Items outside of Adjusted EBITDA are not reported by segment, since they are excluded from the measure of segment profitability reviewed by the CODM. The Company’s CODM does not use segment assets to allocate resources or to assess performance of the segments and, therefore, total segment assets have not been disclosed.

The tables below present segment information reconciled to consolidated Total Net Revenue and Net Income (Loss) Before Income Taxes, as well as interest income and expense included in segment Adjusted Net Revenue and Adjusted EBITDA, for the periods indicated (in thousands).

PROSPER FUNDING LLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

Prosper Funding LLC (“PFL”) was formed in the state of Delaware in February 2012 as a limited liability company with Prosper Marketplace, Inc. (“PMI”) as its sole equity member. Except as the context otherwise requires, as used in these Notes to the condensed consolidated financial statements of Prosper Funding LLC, “PFL,” and the “Company” refers to Prosper Funding LLC and its wholly owned subsidiary, Prosper Depositor LLC, a Delaware limited liability company, on a consolidated basis.

The unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”) and disclosure requirements for interim financial information and the requirements of Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2023. The balance sheet at December 31, 2023 has been derived from the audited financial statements at that date. Management believes these unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

PFL did not have any items of other comprehensive income or loss for any of the periods presented in the condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023.

The preparation of PFL's condensed consolidated financial statements and related disclosures in conformity with US GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in its condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities. These judgments, estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions, and the differences could be material.

2. Summary of Significant Accounting Policies

PFL's significant accounting policies are included in Note 2, Summary of Significant Accounting Policies, in PFL’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no changes to these accounting policies during the first three months of 2024.

Fair Value Measurements

Financial instruments consist principally of Cash and Cash Equivalents, Restricted Cash, Borrower Loans, Loans Held for Sale, Accounts Receivable, Accounts Payable and Accrued Liabilities, Payable to Investors and Notes. The estimated fair values of Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable and Accrued Liabilities, and Payable to Investors approximate their carrying values because of their short-term nature.

Refer to Note 7 for additional fair value disclosures.

Restricted Cash

Restricted Cash consists primarily of cash deposits, money market funds and short-term certificate of deposit accounts held as collateral as required for long term leases, loan funding and servicing activities, and cash that investors have on our marketplace that has not yet been invested in Borrower Loans or disbursed to the investor.

53

Borrower Loans, Loans Held for Sale and Notes

With respect to the Note Channel, PFL purchases Borrower Loans from WebBank, then issues Notes and holds the Borrower Loans until maturity. The obligation to repay a series of Notes funded through the Note Channel is dependent upon the repayment of the associated Borrower Loan. Borrower Loans and Notes funded through the Note Channel are carried on PFL’s condensed consolidated balance sheets as assets and liabilities, respectively.

PFL places Borrower Loans and Loans Held for Sale on non-accrual status when they are 120 days past due. When a loan is placed on non-accrual status, PFL stops accruing interest and reverses all accrued but unpaid interest as of such date. Additionally, PFL charges-off Borrower Loans and Loans Held for Sale when they are 120 days past due. The fair value of loans 120 days past due generally consists of the expected recovery from debt sales in subsequent periods.

Management has elected the fair value option for Borrower Loans, Loans Held for Sale, and Notes. Changes in fair value of Borrower Loans are largely offset by the changes in fair value of Notes due to the borrower payment-dependent design of the Notes. Changes in fair value of Borrower Loans, Loans Held for Sale and Notes are included in “Change in Fair Value of Financial Instruments, Net” on the condensed consolidated statements of operations.

PFL primarily uses a discounted cash flow model to estimate the fair value of Borrower Loans, Loans Held for Sale and Notes. The key assumptions used in the valuation include default rates and prepayment rates derived primarily from historical performance and discount rates based on estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

March 2029. As of December 31, 2023, outstanding Borrower Loans had original maturities of either 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and had various original maturity dates through December 2028.

As of March 31, 2024, Borrower Loans that were 90 days or more delinquent had an aggregate principal amount of $5.2 million and a fair value of $0.8 million. As of December 31, 2023, Borrower Loans that were 90 days or more delinquent had an aggregate principal amount of $4.5 million and a fair value of $0.9 million. PFL places loans on non-accrual status when they are over 120 days past due. As of March 31, 2024 and December 31, 2023, Borrower Loans in non-accrual status had a fair value of $0.8 million and $0.8 million, respectively.

On September 25, 2023, Prosper completed the PMIT 2023-1 transaction, a securitization of Borrower Loans originated through Prosper’s marketplace platform. PFL served as the sole sponsor for this securitization. Loans eligible for securitization that were funded through the PWIIT Warehouse Line were contributed to the PMIT 2023-1 securitization. Loans that were not eligible for securitization, with an aggregate outstanding principal balance of $7.7 million and a fair value of $2.0 million, were contributed to PFL, and are included in “Borrower Loans, at Fair Value” on the accompanying condensed consolidated balance sheet. The fair value of these Borrower Loans was recorded as a deemed Contribution of Borrower Loans from Parent on the condensed consolidated statement of member’s equity and as a non-cash financing activity on the condensed consolidated statement of cash flows.

On March 28, 2024, Prosper completed another securitization of Borrower Loans originated through Prosper’s marketplace platform, PMIT 2024-1. PFL served as the sole sponsor for this securitization. Loans eligible for securitization that were funded through the PWIT Warehouse Line were contributed to the PMIT 2024-1 securitization. Loans that were not eligible for securitization, with an aggregate outstanding principal balance of $4.5 million and a fair value of $1.6 million, were contributed to PFL, and are included in “Borrower Loans, at Fair Value” on the accompanying condensed consolidated balance sheet. The fair value of these Borrower Loans was recorded as a deemed Contribution of Borrower Loans from Parent on the condensed consolidated statement of member’s equity and as a non-cash financing activity on the condensed consolidated statement of cash flows.

5. Servicing Assets

PFL accounts for Servicing Assets at their estimated fair values with changes in fair values recorded in Servicing Fees, Net on the condensed consolidated statements of operations. The initial asset is recognized when PFL sells Borrower Loans to unrelated third-party buyers through the Whole Loan Channel and the servicing rights are retained. PFL recognized a loss on the sale of such Borrower Loans in the amount of $10.5 million and $0.6 million for the three months ended March 31, 2024 and 2023, respectively, recorded in (Loss) Gain on Sale of Borrower Loans on the condensed consolidated statements of operations.

As of March 31, 2024, Borrower Loans that were sold, but for which PFL retained servicing rights, had a total outstanding principal balance of $3.5 billion, original terms of 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and various original maturity dates through March 2029. As of December 31, 2023, Borrower Loans that were sold, but for which PFL retained servicing rights, had a total outstanding principal balance of $3.5 billion, original terms of either 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and various original maturity dates through December 2028.

Contractually-specified servicing fees and ancillary fees totaled $9.4 million and $10.3 million for the three months ended March 31, 2024 and 2023, and are included in Servicing Fees, Net on the condensed consolidated statements of operations.

Fair Value Valuation Method

PFL uses a discounted cash flow valuation methodology generally consisting of developing an estimate of future cash flows that are expected to occur over the life of a financial instrument and then discounting those cash flows at a rate of return that results in the fair value amount.

Significant unobservable inputs presented in the table within Note 7 are those that PFL considers significant to the estimated fair values of the Level 3 Servicing Assets. The following is a description of the significant unobservable inputs provided in the table.

Market Servicing Rate

PFL estimates adequate market servicing rates that would fairly compensate a substitute servicer should one be required, which includes the profit that would be demanded in the marketplace. This rate is stated as a fixed percentage of outstanding principal balance on a per annum basis. With the assistance of a valuation specialist, PFL estimates these market

55

servicing rates based on observable market rates for other loan types in the industry and bids from sub-servicing providers, adjusted for the unique loan attributes that are present in the specific loans that PFL sells and services and information from backup service providers.

Discount Rate

The discount rate is a rate of return used to discount future expected cash flows to arrive at a present value, which represents the fair value of the loan servicing rights. Management used a range of discount rates for the Servicing Assets based on comparable observed valuations of similar assets and publicly available disclosures related to servicing valuations, with comparability adjustments made to account for differences with PFL’s Servicing Assets.

Default Rate

The default rate presented in Note 7 is an annualized, average estimate considering all Borrower Loan categories (i.e., risk ratings and duration), and represents an aggregate of conditional default rate curves for each credit grade or Borrower Loan category. Each point on a particular Borrower Loan category’s curve represents the percentage of principal expected to default per period based on the term and age of the underlying Borrower Loans. The assumption regarding defaults directly reduces servicing revenues because the amount of servicing revenues received is based on the amount collected each period.

Prepayment Rate

The prepayment rate presented in Note 7 is an annualized, average estimate considering all Borrower Loan categories (i.e., risk ratings and duration), and represents an aggregate of conditional prepayment rate curves for each credit grade or Borrower Loan category. Each point on a particular Borrower Loan category’s curve represents the percentage of principal expected to prepay per period based on the term and age of the underlying Borrower Loans. Prepayments reduce servicing revenues as they shorten the period over which PFL expects to collect fees on the Borrower Loans, which is used to project future servicing revenues.

6. Income Taxes

PFL incurred no income tax provision for the three months ended March 31, 2024 and 2023. PFL is a U.S. disregarded entity and its income and loss are included in the income tax reporting of its parent, PMI. Since PMI is in a taxable loss position, is not currently subject to income taxes, and has fully reserved against its deferred tax asset, the net effective tax rate for PFL is 0%.

7. Fair Value of Assets and Liabilities

PFL has elected to record certain financial instruments at fair value on the balance sheet. PFL classifies Borrower Loans, Loans Held for Sale and Notes as financial instruments and assesses their fair value each on a quarterly basis for financial statement presentation purposes. Gains and losses on these financial instruments are shown separately on the condensed consolidated statements of operations.

As of March 31, 2024 and December 31, 2023, the discounted cash flow methodology used to estimate the Notes fair values used the same projected cash flows as the related Borrower Loans. As demonstrated in the table below, the fair value adjustments for Borrower Loans were largely offset by the fair value adjustments of the Notes due to the borrower payment dependent design of the Notes and because the principal balances of the Borrower Loans approximated the principal balances of the Notes.

Assets and liabilities carried at fair value on the balance sheets are classified among three levels based on the observability of the inputs used to determine fair value:

Level 1 — The valuation is based on quoted prices in active markets for identical instruments.

Level 2 — The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation methodologies for which all significant assumptions are observable in the market.

Level 3 — The valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the instrument. Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar methodologies, which incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument or valuations that require significant management judgment or estimation.

56

Fair values of assets or liabilities are determined based on the fair value hierarchy, which requires an entity to maximize the use of quoted prices and observable inputs and to minimize the use of unobservable inputs when measuring fair value. Various valuation methodologies are utilized, depending on the nature of the financial instrument, including the use of market prices for identical or similar instruments, or discounted cash flow models. When possible, active and observable market data for identical or similar financial instruments are utilized. Alternatively, fair value is determined using assumptions that management believes a market participant would use in pricing the asset or liability.

Financial Instruments Recorded at Fair Value

The fair value of the Borrower Loans and Notes are estimated using discounted cash flow methodologies based upon a set of valuation assumptions. The primary cash flow assumptions used to value such Borrower Loans and Notes include default and prepayment rates derived primarily from historical performance and discount rates that reflect estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

The following tables present the fair value hierarchy for assets and liabilities measured at fair value (in thousands):

March 31, 2024	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Total
Assets:
Borrower Loans, at Fair Value	$	—	$	—	$	322,441	$	322,441
Servicing Assets	—		—		13,785		13,785
Total Assets	$	—	$	—	$	336,226	$	336,226
Liabilities:

Loan Trailing Fee Liability	—		—		2,938		2,938
Total Liabilities	$	—	$	—	$	319,516	$	319,516

December 31, 2023	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Total
Assets:
Borrower Loans, at Fair Value	$	—	$	—	$	324,311	$	324,311
Servicing Assets	—		—		13,818		13,818
Total Assets	$	—	$	—	$	338,129	$	338,129
Liabilities:
Notes, at Fair Value	$	—	$	—	$	321,966	$	321,966
Loan Trailing Fee Liability	—		—		2,942		2,942
Total Liabilities	$	—	$	—	$	324,908	$	324,908

As PFL’s Borrower Loans, Notes, Servicing Assets and loan trailing fee liability do not trade in an active market with readily observable prices, PFL uses significant unobservable inputs to measure the fair value of these assets and liabilities. Financial instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. These fair value estimates may also include observable, actively quoted components derived from external sources. As a result, the realized and unrealized gains and losses for assets and liabilities within the Level 3 category may include changes in fair value that were attributable to both observable and unobservable inputs. PFL did not transfer any assets or liabilities in or out of Level 3 for the three months ended March 31, 2024 or March 31, 2023.

57

Significant Unobservable Inputs

The following tables present quantitative information about the significant unobservable inputs used for PFL’s Level 3 fair value measurements at the dates presented:

(1) Servicing assets associated with loans enrolled in a relief program offered by the Company as of March 31, 2024 and December 31, 2023 were measured using a market servicing rate assumption of 84.2 basis points. This rate was estimated using a multiplier consistent with observable market rates for other loan types, applied to the base market servicing rate assumption.

(2) Excludes collection fees that would be passed on to a hypothetical third-party servicer. As of March 31, 2024 and December 31, 2023, the market rate for collection fees and non-sufficient fund fees was assumed to be 6 basis points and 5 basis points, respectively, for a total market servicing rate range of 69.3 - 90.2 basis points and a total market servicing rate of 68.3 - 89.2 basis points, respectively.

	Range
Loan Trailing Fee Liability	March 31, 2024	December 31, 2023
Discount rate	15.0% - 25.0%	15.0% - 25.0%

Key economic assumptions are used to compute the fair value of Servicing Assets. The sensitivity of the current fair value to immediate changes in assumptions at March 31, 2024 and December 31, 2023 for Servicing Assets are presented in the following table (in thousands, except percentages).

Servicing Assets	March 31, 2024			December 31, 2023
Fair value, using the following assumptions:	$	13,785		$	13,818
Weighted-average market servicing rate	0.65		%	0.65		%
Weighted-average prepayment rate	19.78		%	19.96		%
Weighted-average default rate	13.51		%	14.74		%
Fair value resulting from:
Market servicing rate increase of 0.025%	$	12,907		$	12,945
Market servicing rate decrease of 0.025%	$	14,664		$	14,691
Fair value resulting from:
Applying a 1.1 multiplier to prepayment rate	$	13,471		$	13,502
Applying a 0.9 multiplier to prepayment rate	$	14,105		$	14,139
Fair value resulting from:
Applying a 1.1 multiplier to default rate	$	13,503		$	13,534
Applying a 0.9 multiplier to default rate	$	14,069		$	14,104

These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a variation in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects.

8. Commitments and Contingencies

In the normal course of its operations, PFL becomes involved in various legal actions. PFL maintains provisions it considers to be adequate for such actions. The Company does not believe it is probable that the ultimate liability, if any, arising out of any such matters will have a material effect on financial condition, results of operations or cash flows.

Operating Commitments

PMI, along with PFL, and WebBank has entered into: (i) an Asset Sale Agreement, dated July 1, 2016, between PFL and WebBank, as most recently amended by a Seventh Amendment dated February 28, 2024 (as amended, the “Sale Agreement”); (ii) the Marketing Agreement, dated July 1, 2016, between PMI and WebBank, as most recently amended by a Seventh Amendment dated February 28, 2024 (as amended, the “Marketing Agreement”); and (iii) the Stand By Purchase Agreement, dated July 1, 2016, between PMI and WebBank, as most recently amended by a Fourth Amendment dated February 28, 2024 (as amended, the “Purchase Agreement” and, collectively with the Sale Agreement and the Marketing Agreement, the “Origination and Sale Agreements”). Under the Origination and Sale Agreements, all Borrower Loans originated through the marketplace are made by WebBank under its bank charter.

The Origination and Sale Agreements contain terms through February 1, 2027. Prosper is required, under the Origination and Sale Agreements, to maintain certain collateral requirements. In addition, pursuant to the Marketing Agreement, the marketing fee that Prosper receives in connection with the origination of each loan is partially reduced by an amount (the “Designated Amount”) calculated as a percentage of the principal amount of such loan based on the aggregate principal amount of loans originated for the applicable month. To the extent the aggregate Designated Amount for all loans originated during any month is less than $100,000 through February 1, 2027, Prosper is required to pay WebBank an amount

61

equal to such deficiency. Accordingly, the minimum fee is $0.9 million for the remaining nine months of 2024, $1.2 million in 2025, $1.2 million in 2026 and $0.1 million in 2027.

Additionally, under the Origination and Sale Agreements, Prosper is required to maintain a minimum net liquidity of $15.0 million at all times during the term of the agreement. Net liquidity is defined as the sum of Cash, Cash Equivalents and Available for Sale Investments. Violation of this covenant can result in termination of the contract with WebBank. As of March 31, 2024, the Company was in compliance with the covenant.

Transaction Fee Refunds

Prosper assumes WebBank’s liability under Utah law to refund the pro-rated amount of any transaction fees collected in excess of 5%, in the event the underlying borrower prepays the loan before full maturity. PFL has accrued $3.9 million and $1.6 million as of March 31, 2024 and December 31, 2023, respectively, related to anticipated future refunds under this obligation.

Loan Purchase Commitments

Under the terms of PFL’s agreement with WebBank, PFL is committed to purchase $15.0 million of Borrower Loans that WebBank originated during the last two business days of the quarter ended March 31, 2024. PFL will purchase these Borrower Loans within the first three business days of the quarter ending June 30, 2024.

Repurchase Obligation

Under the terms of the loan purchase agreements between PFL and investors that participate in the Whole Loan Channel, PFL may, in certain circumstances, become obligated to repurchase a Borrower Loan from an investor. Generally, these circumstances include the occurrence of verifiable identity theft, the failure to properly follow personal loan listing or bidding protocols, or a violation of the applicable federal, state, or local lending laws. The fair value of the indemnification and repurchase obligation is estimated based on historical experience. PFL recognizes a liability for the repurchase and indemnification obligation when the Borrower Loans are issued. Indemnified or repurchased Borrower Loans associated with violations of federal, state, or local lending laws or verifiable identity theft are written off at the time of repurchase or at the time an indemnification payment is made. The maximum potential amount of future payments associated under this repurchase obligation is the outstanding balances of the Borrower Loans issued through the Whole Loan Channel, which as of March 31, 2024 is $3.5 billion. PFL has accrued $0.4 million and $0.5 million as of March 31, 2024 and December 31, 2023, respectively, in regard to this obligation.

Under the terms of the indenture and investor registration agreement, Prosper may, in certain circumstances, become obligated to either repurchase a Note or indemnify the investor for any losses resulting from nonpayment of a Note purchased in the Retail Channel. The decision to repurchase or indemnify is in Prosper’s sole discretion. These circumstances include, but are not limited to, the occurrence of verifiable identity theft, a technical error in the automated bidding tools which results in the purchase of a Note that does not match the investor’s investment criteria, or situations in which a personal loan listing includes a Prosper Rating that is different from the Prosper Rating that should have appeared in the listing for the corresponding Borrower Loan because either PFL inaccurately input data into, or inaccurately applied, the formula for determining the Prosper Rating and, as a result, the interest of the investor is materially and adversely affected. During the three months ended March 31, 2024 the Company repurchased $0.1 million of Notes under these circumstances, and has agreed to indemnify additional Notes with an unpaid principal balance of $0.7 million as of March 31, 2024.

Regulatory Contingencies

PFL accrues for contingencies when a loss from such contingencies is probable and the amount of loss can be reasonably estimated. In determining whether a loss is probable and if it is possible to quantify the amount of the estimated loss, PFL reviews and evaluates its litigation and regulatory matters on at least a quarterly basis in light of potentially relevant factual and legal developments. If PFL determines that an unfavorable outcome is not probable or that the amount of a loss cannot be reasonably estimated, PFL does not accrue for a potential litigation loss. If an unfavorable outcome is probable and PFL can estimate a range of outcomes, PFL records the amount management considers to be the best estimate within the range of potential losses that are both probable and estimable; however, if management cannot quantify the amount of the estimated loss, then PFL records the low end of the range of those potential losses.

62

West Virginia Matter

In February 2020, Prosper received a proposed Assurance of Discontinuance (an “AOD”) from the Attorney General of the State of West Virginia (the “WV Attorney General”) requesting that, without in any way admitting that any of its prior practices were in violation of the West Virginia Consumer Credit and Protection Act (the “Consumer Act”), Prosper agree to certain terms and conditions regarding its past and potential future conduct of its business with respect to customers in West Virginia, including a release by the WV Attorney General of any claims it may have related to the matters identified in the AOD.

We cannot predict the outcome of the matter and any potential fines or penalties, if any, that may arise from the matter. Further, we are unable to estimate a range of outcomes and as a result no accrual has been made.

No loans have been originated through the Prosper platform to West Virginians since June 2016 and the final loan originated through the Prosper platform to a borrower in West Virginia was repaid in October 2021.

9. Related Parties

Since inception, PFL has engaged in various transactions with its directors, executive officers, PMI, and immediate family members and other affiliates of its directors, executive officers, and PMI. PFL believes that all of the transactions described below were made on terms no less favorable to PFL than could have been obtained from unaffiliated third parties.

PFL’s executive officers and directors who are not executive officers participate in its marketplace by placing bids and purchasing Notes. The aggregate amount of the Notes purchased and the income earned by parties deemed to be related parties of PFL for the three months ended March 31, 2024 and 2023 are summarized below (in thousands):

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This management’s discussion and analysis of financial condition and results of operations, or MD&A, contains forward-looking statements that involve risks and uncertainties. Please see “Forward-Looking Statements” in this Quarterly Report on Form 10-Q for a discussion of the uncertainties, risks, and assumptions associated with these statements. This discussion should be read in conjunction with Prosper’s historical condensed consolidated financial statements and related notes thereto and the other disclosures contained elsewhere in this Quarterly Report on Form 10-Q. The results of operations for the periods reflected herein are not necessarily indicative of results that may be expected for future periods, and Prosper’s actual results may differ materially from those discussed in the forward-looking statements as a result of various factors, including but not limited to those included in the “Risk Factors” sections and elsewhere in this Quarterly Report on Form 10-Q and Prosper’s Annual Report on Form 10-K for the year ended December 31, 2023.

PROSPER MARKETPLACE, INC.

Overview

Our vision is to transform lives by providing affordable financial solutions through the simplest and most trusted platform. We currently offer access to three lending products, each of which supports our vision: (i) unsecured personal loans through a personal loan marketplace which connects eligible consumer borrowers with individual and institutional investors, (ii) a Credit Card product available to eligible borrowers, and (iii) Home Equity Products available to eligible homeowners.

We believe our business model has key advantages relative to traditional banks, including (i) an innovative marketplace model that efficiently connects qualified supply and demand of capital, (ii) online operations that substantially reduce the need for physical infrastructure and improve convenience, and (iii) use of advanced technology and artificial intelligence to deliver simple, fast, personalized, and transparent solutions that can improve consumers’ financial health as they move across the credit spectrum. We do not operate physical branches or incur expenses related to infrastructure like traditional banks or consumer finance institutions. As part of operating our marketplace, we verify the identity of borrowers and assess borrowers’ credit risk profile using a combination of public and proprietary data. Our proprietary technology automates several loan origination and servicing functions, including the borrower application process, data gathering, underwriting, credit scoring, loan funding, investing and servicing, regulatory compliance and fraud detection.

For the year ended December 31, 2023, our marketplace facilitated $2.2 billion in Borrower Loan originations, of which $1.9 billion were funded through our Whole Loan Channel, representing 89% of the total Borrower Loans originated through our marketplace during this period. From inception through March 31, 2024, our marketplace has facilitated $26.2 billion in Borrower Loan originations, of which $23.5 billion were funded through our Whole Loan Channel, representing 90% of the total Borrower Loans originated through our marketplace during this period. For the three months ended March 31, 2024, our marketplace facilitated $536.8 million in Borrower Loan originations, a decrease of 15% from the same period in 2023. The percentage of loans funded through the Whole Loan Channel for the three months ended March 31, 2024 was 91%.

As a credit marketplace, we believe our customers are highly susceptible to uncertainties and negative trends, real or perceived, in the markets driven by, among other factors, general economic conditions in the United States and abroad. These external economic conditions and resulting trends or uncertainties could adversely impact our customers’ ability or desire to participate on our marketplace as borrowers or investors and, consequently, could negatively affect our business and results of operations.

Recent Developments

In March 2024, we completed the PMIT 2024-1 transaction, a securitization of unsecured personal whole loans that were previously originated through our marketplace platform. Based on the terms of the underlying agreements, the PWIT Warehouse Line agreed to contribute Borrower Loans with an aggregate outstanding principal balance of $148.9 million as of the established cutoff date of February 14, 2024, to PMIT 2024-1. On March 28, 2024, these Borrower Loans, with an updated outstanding principal balance of $138.0 million, were contributed to the PMIT 2024-1 securitization. PMIT 2024-1 issued senior notes and residual certificates to finance the purchase of the Borrower Loans. The notes were sold to third-party investors, while PMI acquired 100% of the residual certificates as the majority-owned affiliate of PFL, the sole sponsor of the PMIT 2024-1 securitization. In addition to holding the residual certificates, we have continued involvement with the Borrower Loans through our role as the servicer. Because PMIT 2024-1 is a deemed VIE, and we are the primary beneficiary, we consolidate the securitization trust into our financial statements. Borrower Loans held in the consolidated trust are included in “Borrower Loans, at Fair Value,” and the notes sold to third-party investors are presented in “Notes Issued by Securitization

64

Trust” on the condensed consolidated balance sheets. See Note 7, Securitizations, of the notes to the accompanying condensed consolidated financial statements for further details.

In conjunction with the securitization, the entire portfolio of loans funded by the PWIT Warehouse Line were either contributed to the PMIT 2024-1 Transaction (loans eligible for securitization) or contributed to PFL (loans not eligible for securitization). Proceeds from the sale were used to pay down the outstanding balance of principal and interest on the PWIT Warehouse Line of $130.4 million, and the PWIT Warehouse Line was terminated at that time. After covering securitization transaction fees and expenses, PMI received the remaining proceeds. As a result of terminating the PWIT Warehouse Line, we accelerated the amortization of deferred debt issuance costs of $0.7 million into interest expense. See Note 11, Debt, of the notes to the accompanying condensed consolidated financial statements for further details.

(2) Adjusted Net Revenue and Adjusted EBITDA are non-GAAP financial measures. For more information regarding these measures and the reconciliation to Total Net Revenue and Net Income (Loss), respectively, the most comparable US GAAP measures, see “Non-GAAP Financial Measures.”

Personal Loan Originations

From inception of the Company through March 31, 2024, a total of 2,094,453 Borrower Loans, totaling $26.2 billion were originated through our marketplace.

For the three months ended March 31, 2024, 37,293 Borrower Loans totaling $536.8 million were originated through Prosper’s marketplace, compared to 45,854 Borrower Loans totaling $631.9 million during the three months ended March 31, 2023. This represents a unit decrease of 19% and a dollar decrease of 15%. The originations decrease for the quarter ended March 31, 2024 versus the quarter ended March 31, 2023 was primarily due to the reduced usage of our Warehouse Lines to purchase loans, partially offset by increased third-party investor demand.

65

Personal loan origination volume by Prosper Rating was as follows for the periods presented (in millions, except percentages):

	Three Months Ended March 31,
	2024				2023
	Amount		%		Amount		%
AA	$	43.8	8	%	$	87.4	14	%
A	84.5		16	%	91.1		14	%

Other (1)	77.2		14	%	49.3		8	%
Total	$	536.8			$	631.9

(1) Represents personal loans funded through the Prosper platform via the Whole Loan Channel but not assigned Prosper Ratings.

For the three months ended March 31, 2024, compared to the corresponding period in 2023, the total and mix of personal loan originations on the Prosper platform reflects a relatively increased demand for higher risk and higher yield loans by third-party investors. This includes personal loans not assigned Prosper ratings, which are sold only to institutional investors and are based on specific underwriting criteria and custom risk models developed by those investors.

Personal Loan Serviced Portfolio and Whole Loans Outstanding

Our personal loan serviced portfolio consists of all Borrower Loans that we service both through the Note and Whole Loan Channels. Borrower Loans funded through the Whole Loan Channels include loans that we hold in consolidated trusts, as well as those sold to third parties. Our personal loan serviced portfolio decreased $0.3 billion, or 7%, from March 31, 2023 to March 31, 2024. This decrease is primarily due to decreased year-over-year originations for the past several quarters, as well as a reduction in personal loans purchased through our consolidated warehouse trusts.

The outstanding balance of Borrower Loans sold through our Whole Loan Channel serves as a primary driver of our Servicing Assets. Whole loans outstanding decreased $0.3 billion, or 7%, from March 31, 2023 to March 31, 2024 due to the same factors that drove the decrease in the personal loan serviced portfolio.

Net Income (Loss)

See the section titled “Results of Operations” below, for the discussion on significant changes in Net Income (Loss) year-over-year.

Results of Operations

Overview

The following table summarizes our net income (loss) for the three months ended March 31, 2024 and 2023 (in thousands, except percentage):

	Three Months Ended March 31,
	2024		2023		Change		% Change
Total Net Revenues	$	43,493	$	40,372	$	3,121	8	%
Total Expenses	21,172		49,392		(28,220)		(57)	%
Net Income (Loss) Before Taxes	22,321		(9,020)		31,341		n/m
Income Tax Expense	(26)		(70)		44		(63)	%
Net Income (Loss)	$	22,295	$	(9,090)	$	31,385	n/m

n/m: not meaningful

Total Net Revenues for the three months ended March 31, 2024 increased $3.1 million as compared to the same period in 2023. The increase was largely attributable to a $9.7 million increase in Transaction Fees, Net, due to a revised WebBank transaction fee schedule starting in the fourth quarter of 2023, with some offsetting impact from the lower personal loan origination volume during this time, as discussed above. Additionally, total Net Revenues from Change in Fair Value of Financial Instruments, Net increased $5.9 million year-over-year, due primarily to an increase in fair values of our consolidated warehouse and securitization loans due to reduced delinquencies and charge-offs, partially offset by the impact from higher interest rates. There was also an increase in fair value gains on our Credit Card Derivative of $1.7 million, which is reflective of a change in estimate related to the discount rate used to value the Credit Card Derivative, as well as overall growth in our Credit Card portfolio during this time. Finally, there was a $1.2 million increase in Servicing Fees, Net, due primarily to changes in the fair value of the credit card servicing obligation, due to a change in estimate related to the discount rate applied to the cash flows associated with that obligation, partially offset by an increase in collection agency costs. These increases were partially offset by a $9.1 million decrease from Loss on Sale of Borrower Loans, due primarily to additional incentives provided to whole loan investors (“incentives”) during the quarter ended March 31, 2024. There was also a $4.6 million decrease in Total Interest Income (Expense), Net, due in part to a decrease in the average outstanding principal balance of loans held in consolidated warehouse and securitization trusts, combined with the impact from increased debt discount and issuance cost amortization from the termination of the PWIT Warehouse Line in March 2024 and the PMIT 2023-1 securitization established in September 2023.

Total Expenses for the three months ended March 31, 2024 decreased $28.2 million as compared to the same period in 2023, primarily due to the Change in Fair Value of Convertible Preferred Stock Warrants, which is in turn driven by changes in the fair value of the underlying Convertible Preferred Stock. Specifically, the gain for the three months ended March 31, 2024 totals $27.7 million, which compares to a gain of $4.3 million for the corresponding period in 2023, a change of $23.4 million. Additionally, there was a combined $4.6 million decrease in Origination and Servicing, Sales and Marketing expenses and General and Administrative expenses, as costs decreased in response to lower personal loan originations. Accordingly, the net income for the three months ended March 31, 2024 increased $31.4 million when compared to the net loss for the three months ended March 31, 2023.

n/m: not meaningful

Transaction Fees, Net

We earn a transaction fee upon the successful origination of all Borrower Loans facilitated through our marketplace. Prosper receives payments from WebBank as compensation for the activities we perform on behalf of WebBank. Our fee is determined by the term and credit grade of the Borrower Loans that we facilitate on our marketplace and WebBank originates. We record the transaction fee revenue net of any fees paid by us to WebBank.

We also earn various program fees from our Credit Card product, such as interchange fees, annual fees and late fees, and broker fees from our Home Equity product. These program and broker fees are recorded within Transaction Fees, Net.

Transaction Fees, Net increased $9.7 million, or 29%, for the three months ended March 31, 2024, as compared to the corresponding period in 2023. This increase is generally due to the revised WebBank transaction fee schedule starting the fourth quarter of 2023. Under the revised WebBank transaction fee schedule, transaction fees now range from 1.0% to 7.99%, depending on the term and credit grade of the Borrower Loan, as compared to 1.0% to 5.0% under the previous schedule. Transaction fees above 5.0% are refundable on a pro-rated basis upon the full prepayment of the related Borrower Loan under Utah law, where WebBank is domiciled, and thus the impact of these increased transaction fees is reduced by expected refunds. The impact from change in transaction fees was partially offset by the lower personal loan origination volume during the first quarter of 2024, compared to the corresponding period of 2023, as discussed above. Finally, there was a positive impact from continued growth in our Credit Card product, as we recognized approximately $5.8 million in program fees under our Credit Card product for the three months ended March 31, 2024, as compared to $3.4 million for the corresponding period of 2023, an increase of $2.4 million.

Servicing Fees, Net

Investors who purchase Borrower Loans through the Whole Loan Channel typically pay us a servicing fee which is generally set at 1.0% per annum of the outstanding principal balance of the Borrower Loan prior to applying the current payment, plus an additional 0.075% per annum to cover the Loan Trailing Fee. The Servicing Fee compensates us for the costs incurred in servicing the Borrower Loan, including managing payments from borrowers, payments to investors and maintaining investors’ account portfolios. We record Servicing Fees from investors as a component of operating revenues when received. We also include any collection fees received, net of collection agency expenses, in Servicing Fees.

68

In addition, we are contractually obligated to service the entire portfolio under our Credit Card product. Our banking partner, Coastal Community Bank (“Coastal”), pays us a servicing fee of 1.0% per annum of the daily outstanding principal balance of all cards designated as Coastal allocations. These allocations represented approximately 10% of the portfolio through March 31, 2024, but will be 5% starting April 1, 2024 as a result of an amendment to the Program Agreement executed in March 2024. To the extent that these contractual fees are less than the market servicing rate that would be required by a market participant to service the entire portfolio, a servicing obligation is recorded. Changes to this servicing obligation are included in Servicing Fees, Net.

The increase of $1.2 million, or 24%, in Servicing Fees for the three months ended March 31, 2024, as compared to the corresponding period in 2023, is primarily due to a $1.8 million increase from changes in the fair value of the credit card servicing obligation. As discussed in Note 8, Fair Value of Assets and Liabilities, of the accompanying condensed consolidated financial statements, a change in estimate related to the application of a revised discount rate to this servicing obligation resulted in an increase in revenue from fair value changes of $1.9 million for the three months ended March 31, 2024. This increase was partially offset by a $0.5 million increase in collection agency costs, net of collection fees income, as we increased our usage of these agencies in the first quarter of 2024.

Loss on Sale of Borrower Loans

Loss on Sale of Borrower Loans consists of net losses on Borrower Loans sold through the Whole Loan Channel, net of any incentives provided at the time of sale. Starting in the second half of 2022, due to market volatility and incentives offered by competitors, we started providing additional incentives to our whole loan investors. For the three months ended March 31, 2024, these incentives increased $9.5 million from the corresponding period in the prior year. Excluding the impact of these incentives, the remaining changes in Loss on Sale of Borrower Loans for the three months ended March 31, 2024 as compared to the same period in 2023, was an increased gain of $0.4 million, primarily due to an increase in whole loans sold to third parties year-over-year.

Other Revenues

Other Revenues consists primarily of credit referral and incentive fees. Credit referral fees are earned from partner companies for the referral of customers on our platform, while incentive fees are earned from partner companies through our incentive programs. Other Revenues remained relatively flat for the three months ended March 31, 2024, as compared to the corresponding period in 2023.

Interest Income on Borrower Loans and Loans Held for Sale and Interest Expense on Financial Instruments

We recognize Interest Income on Borrower Loans and Loans Held for Sale using the accrual method based on the stated interest rate to the extent we believe it to be collectible. We record interest expense on the corresponding fractional Notes, at Fair Value, Notes Issued by Securitization Trust and Warehouse Lines based on the contractual interest rates. The interest rate on fractional Notes, at Fair Value is generally 1% lower than the interest rate on the corresponding Borrower Loans to compensate us for servicing the underlying Borrower Loans. Additionally, Interest Expense associated with Term Loan proceeds used to purchase Loans Held for Sale through our Warehouse Lines is allocated to Net Interest Income.

The decrease of $4.6 million, or 59%, in Total Interest Income (Expense), Net for the three months ended March 31, 2024, as compared to the corresponding period in 2023, is primarily due to a combined $3.4 million decrease in Total Interest Income (Expense), Net generated from Loans Held for Sale, net of interest expense incurred on the Warehouse Lines, and securitized Borrower Loans, net of interest expense incurred on Notes Issued by Securitization Trust, during this period. This decrease is reflective of the reduced average outstanding balance of loans held in these consolidated trusts year-over-year, as well as the related decrease in the associated liabilities. Additionally, we incurred $0.7 million in accelerated amortization of debt issuance costs upon the termination of the PWIT Warehouse Line in March 2024, and $0.5 million of debt discount and debt issuance costs amortization related to the PMIT 2023-1 securitization established in September 2023.

Change in Fair Value of Financial Instruments

We record Borrower Loans, Loans Held for Sale, Notes and the Credit Card Derivative at fair value. Changes in the fair value of Borrower Loans funded through the Note Channel are largely offset by the changes in fair value of the Notes due to their borrower payment-dependent structure. Our obligation to pay principal and interest on Notes is equal to the loan payments, if any, that are received on the corresponding Borrower Loan, net of the servicing fee, which is generally 1.0% of the outstanding balance.

We used Warehouse Lines to finance the purchase of Loans Held for Sale for the purpose of earning Net Interest Income and contributing to securitization transactions. Loans Held for Sale consisted primarily of loans held in warehouse

69

trusts. Changes in the fair value of Loans Held for Sale were not offset by changes in the fair value of Warehouse Lines because Warehouse Lines were carried at amortized cost. As discussed below and in Note 11 of the accompanying condensed consolidated financial statements, we terminated our two existing Warehouse Lines in September 2023 and March 2024, respectively, and securitized the related Loans Held for Sale. Because of this, these loans are now classified as Borrower Loans on our consolidated balance sheet.

In September 2023 and March 2024, we sponsored and consolidated two securitization transactions, PMIT 2023-1 and PMIT 2024-1, respectively, with loans that were previously funded through our PWIIT and PWIT Warehouse Lines, respectively. Refer also to Note 7, Securitization, of the accompanying condensed consolidated financial statements for additional information on these securitization transactions. We expect that changes in the fair value of Borrower Loans held by PMIT 2023-1 and PMIT 2024-1 will be negative due to delinquencies and charge-offs, but they could ultimately be negative or positive due to changes in fair value assumptions, such as expected credit performance, prepayment rates and implied market discount rates. Notes issued by PMIT 2023-1 and PMIT 2024-1 are carried at amortized cost on the accompanying condensed consolidated balance sheet, and thus do not impact the Change in Fair Value of Financial Instruments.

We earn interest income on loans held in consolidated warehouse and securitization trusts during the period we own or consolidate the loans, which partially offsets changes in the fair value of these loans. The following tables illustrate the weighted-average composition of the loans held in consolidated warehouse and securitization trusts by Prosper Rating for the periods presented, which is an indicator of their credit quality:

	Three Months Ended March 31, 2023

A	27	%
B	22	%
C	13	%

Total	100	%
(2) The percentages are calculated using the weighted-average of month-end principal balances of Borrower Loans by Prosper Rating.

Fair values of Borrower Loans, Loans Held for Sale and Notes are estimated using discounted cash flow methodologies based upon a set of valuation assumptions. The key assumptions used include default and prepayment rates derived primarily from historical performance, and discount rates based on estimates of the rates of return that investors would require when investing in other financial instruments with similar characteristics. For the three months ended March 31, 2024 and 2023, the Change in Fair Value of Financial Instruments was a gain of $0.2 million and a loss of $5.7 million, respectively.

The decrease in the loss on Change in Fair Value related to Borrower Loans, Loans Held for Sale and Notes for the three months ended March 31, 2024, as compared to the corresponding period in the prior year is largely driven by Loans Held for Sale, due to lower delinquencies and charge-offs, combined with the overall decrease in the average balance of loans held in consolidated warehouse trusts year-over-year, as discussed above. For Loans Held for Sale, the loss from changes in fair value for the three months ended March 31, 2024 was $2.3 million, due to a $1.5 million gain in fair value and $3.8 million in net

70

charge-offs. This compares to the corresponding period in 2023, when there was a loss from changes in fair value of $9.5 million, due to a $3.8 million loss in fair value and $5.7 million in net charge-offs.

We also held a swaption to limit our exposure to fluctuations in SOFR due to our PWIT Warehouse Line, which consisted of two classes of loans that bore interest at SOFR plus a defined spread (see Note 11 of the accompanying condensed consolidated financial statements for further information). This swaption was terminated on March 28, 2024, upon the repayment of our PWIT Warehouse Line in conjunction with the PMIT 2024-1 securitization. The change in fair value of the swaption was immaterial for the three months ended March 31, 2024 and a decrease of $0.5 million for the corresponding period of 2023, resulting in a $0.5 million increase in the gain from Change in Fair Value of Financial Instruments during this time. The overall decrease in the value of the swaption year-over-year, prior to its termination, is largely driven by an increase in the strike price of the swaption in 2023.

For fractional Borrower Loans and Notes (as well as the population of whole loans that are owned directly by PFL), the net impact to the Change in Fair Value of Financial Instruments was a $0.7 million loss for the three months ended March 31, 2024, due to the borrower payment-dependent structure described above, offset by certain timing factors. During the same period of 2023, the net impact from these fractional Borrower Loans and Notes was a $0.4 million loss. For Borrower Loans held in our Securitization Trusts, the loss from changes in fair value was $3.3 million for the three months ended March 31, 2024 and related primarily to delinquencies and charge-offs.

The Credit Card Derivative is recorded at fair value and is primarily reflective of discounted future cash flows from certain features of our Credit Card program that were determined to meet the definition of freestanding derivatives, including interest income, program fees paid to our banking partner Coastal and credit losses, net of recoveries. These cash flows are estimated based upon a set of valuation assumptions, including default and prepayment rates derived primarily from comparable companies and our own historical performance, and discount rates based on estimates of the rates of return that investors would require when investing in other financial instruments with similar characteristics.

Fair value changes related to future cash flows underlying the Credit Card Derivative resulted in a gain of $9.1 million, and the net impact of realized transactions resulted in a loss of $2.7 million for the three months ended March 31, 2024. This compares to the corresponding period in the prior year, when fair value changes related to projected future cash flows underlying the Credit Card Derivative resulted in a gain of $6.1 million, and the net impact of realized transactions resulted in a loss of $1.5 million. As discussed in Note 8, Fair Value of Assets and Liabilities, of the accompanying condensed consolidated financial statements, a change in estimate related to the application of a single discount rate to all components of the Credit Card Derivative resulted in an increase in fair value changes of $7.3 million for the three months ended March 31, 2024. Remaining fluctuations in gains and losses on the Credit Card Derivative for the three month periods ended March 31, 2024, as compared to the same period in the prior year, are largely reflective of the significant growth in the Credit Card portfolio, partially offset by increased charge-offs.

The following table details the changes in fair value of our financial instruments for the three months ended March 31, 2024 and 2023, respectively (in thousands, except percentages):

	Three Months Ended March 31,
	2024		2023

The following table reflects full-time employees as of March 31, 2024 and 2023 by functional area:

	March 31, 2024	March 31, 2023
Origination and Servicing	95	125
Sales and Marketing	30	30
General and Administrative - Research and Development	98	104
General and Administrative - Other	180	197
Total Headcount	403	456

Origination and Servicing

Origination and Servicing costs consist primarily of salaries, benefits and stock-based compensation expense related to our capital markets, collections, customer support and payment processing employees and vendor costs associated with facilitating and servicing personal loans and our Credit Card product. The decrease for the three months ended March 31, 2024 of $0.4 million, or 3%, as compared to the corresponding period in 2023 is primarily due to a $1.2 million decrease in personal loan servicing and origination costs, consistent with the decrease in personal loan originations discussed above. Additionally, compensation costs decreased $0.6 million, driven primarily by decreased headcount. These decreases are partially offset by a $1.2 million increase in third-party servicing costs associated with our Credit Card product, as the underlying portfolio continues to grow, and a $0.3 million increase in depreciation due to the increase in the balance of internal-use software during this time.

Sales and Marketing

Sales and Marketing costs consist primarily of affiliate marketing, search engine marketing, online and offline campaigns, email marketing, public relations and direct mail marketing, as well as compensation expenses such as wages, benefits and stock-based compensation for the employees who support these activities. For the three months ended March 31, 2024, the decrease of $1.5 million, or 9%, from the prior year is due to an overall reduction in marketing and advertising costs, which is generally in line with the decrease in personal loan originations during this time. This includes decreases in marketing partnership costs of $1.2 million and a combined decrease of $1.3 million across digital and email advertising spend. These decreases were partially offset by a $0.9 million increase in direct mail costs. Additionally, compensation expense increased $0.1 million.

General and Administrative - Research and Development

General and Administrative - Research and Development costs consist primarily of salaries, benefits and stock-based compensation expense related to our engineering and product development employees, as well as related vendor costs. The decrease in General and Administrative – Research and Development for the three months ended March 31, 2024, of $1.2 million from the corresponding period in the prior year is primarily due to a decrease of $0.9 million in outsourced services. Additionally, there was an increase of $0.4 million from capitalized internal-use software and web development costs (reducing the expense). Specifically, these capitalized costs were $3.6 million and $3.3 million for the three months ended March 31,

72

2024 and 2023, respectively. Finally, there was $0.2 million decrease in compensation costs, driven by deceased headcount. These decreases were partially offset by a $0.2 million increase in spend on software licenses and subscription costs.

General and Administrative - Other

General and Administrative - Other expenses consist primarily of salaries, benefits and stock-based compensation expense related to our accounting and finance, risk, legal, compliance, human resources and facilities employees, professional fees related to legal and accounting and facilities expenses. The decrease in General and Administrative - Other for the three months ended March 31, 2024 of $1.5 million from the corresponding period in the prior year is due primarily to a $1.3 million decrease in compensation expense, driven by decreased headcount.

Change in Fair Value of Convertible Preferred Stock Warrants

Change in Fair Value of Convertible Preferred Stock Warrants were gains of $27.7 million and $4.3 million for the three months ended March 31, 2024, and 2023, respectively, due to decreases in the fair value of the underlying Convertible Preferred Stock for those periods.

As discussed in Note 13, Convertible Preferred Stock, Convertible Preferred Stock Warrant Liability and Common Stock, of the accompanying condensed consolidated financial statements, staring September 30, 2023, we removed the discount for lack of marketability that was previously applied to the Black-Scholes option price for the Series E and F Warrants, due to a change in valuation methodology. This change in estimate resulted in an increase to the Convertible Preferred Stock Warrant Liability and the Change in Fair Value of Convertible Preferred Stock Warrants of approximately $5.6 million as of March 31, 2024, and for the three months then ended.

Interest Expense on Term Loan

We incurred $3.2 million and $3.0 million in interest costs for the three months ended March 31, 2024 and March 2023, respectively, related to our Term Loan. Refer to Note 11 of the accompanying condensed consolidated financial statements for further information on the Term Loan, including details of the interest rates. We allocated $0.2 million in Term Loan interest costs to Net Interest Income for the three months ended March 31, 2023, as the related Term Loan proceeds were used to purchase Loans Held for Sale through our Warehouse Lines. No such amount was allocated for the three months ended March 31, 2024.

Other Income, Net

Other Income, Net was $1.0 million for the three months ended March 31, 2024, and primarily consists of sublease income, interest income on cash and cash equivalents and other miscellaneous items. The $0.5 million increase in Other Income, Net, for the three months ended March 31, 2024, as compared to the corresponding period in the prior year is primarily attributable to an increase in interest income driven by rising interest rates.

Non-GAAP Financial Measures

Adjusted Net Revenue

Adjusted Net Revenue is a non-GAAP financial measure that we define as our Total Net Revenue adjusted to exclude the impact of interest rates on the fair value of loans held in consolidated trusts and certain infrequent or unusual transactions such as the accelerated amortization of PWIT debt issuance costs. As a result of the termination of the PWIT Warehouse Line in March 2024 (see Note 11, Debt), we accelerated the remaining amortization of the related deferred debt issuance costs into interest expense. We exclude the impact of this accelerated amortization because it is non-cash and because of the infrequent nature of the transaction. Management does not believe that it is reflective of our ongoing operating results. We believe it is useful to investors to exclude the impact of interest rates on the fair value of loans held in consolidated trusts to gain insight into the performance of our consolidated loans, independent of market factors that are beyond management’s control.

Adjusted Net Revenue has limitations as a financial measure, should be considered as supplemental in nature and is not meant as a substitute for Total Net Revenue, which has been prepared in accordance with U.S. GAAP. These limitations include the following:

•Adjusted Net Revenue excludes the impact of interest rates, which may influence the price that a willing buyer would be willing to pay for our personal loans in a hypothetical arm’s length transaction; and

•Other companies, including companies in our industry, may calculate Adjusted Net Revenue differently or not at all, which reduces its usefulness as a comparative measure.

73

Because of these limitations, you should consider Adjusted Net Revenue alongside other financial performance measures, including Total Net Revenue and our financial results presented in accordance with U.S. GAAP. The following table presents a reconciliation of Total Net Revenue to Adjusted Net Revenue for each of the periods indicated (in thousands):

		Three Months Ended March 31,

Accelerated amortization of PWIT debt issuance costs (2)		733		—
	Adjusted Net Revenue	$	46,293	$	41,578
(1) Component of Change in Fair Value of Financial Instruments on the condensed consolidated statements of operations
(2) Component of Interest Expense on Financial Instruments on the condensed consolidated statement of operations

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that we define as Net Income (Loss) adjusted for interest income on Cash and Cash Equivalents, Interest Expense on Term Loan, Income Tax Benefit or Expense, depreciation and amortization, impairment of long-lived assets and Goodwill, stock-based compensation expense, Change in Fair Value of Convertible Preferred Stock Warrants, and certain infrequent or unusual transactions. Starting with the second quarter of 2023, it is also adjusted for the impact of interest rates on the fair value of loans held in consolidated trusts. Prior periods have been updated to match current period presentation. The presentation of non-GAAP financial measures should not be considered in isolation or as a substitute for our financial results prepared in accordance with GAAP.

We consider Adjusted EBITDA to be a helpful indicator of the operational strength and performance of our business and a good measure of our historical operating trends. Management uses Adjusted EBITDA, among other things, to understand and compare operating results across accounting periods, to evaluate our operations and financial performance and for internal planning and forecasting purposes. Inclusion of Adjusted EBITDA is intended to provide investors insight into the manner in which management views the performance of the Company, enhance investors’ evaluation of our operating results, and to facilitate meaningful comparisons of our results between periods. This non-GAAP financial measure should not be considered an alternative to, or more meaningful than, the GAAP financial information provided herein.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations are:

•Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;

•Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•Adjusted EBITDA does not consider the potentially dilutive impact of equity-based charges;

•Adjusted EBITDA does not reflect interest and tax payments that may represent a reduction in cash available to us; and

•Other companies, including companies in our industry, may calculate Adjusted EBITDA differently, which reduces its usefulness as a comparative measure.

The major non-GAAP adjustments, and our basis for excluding them, are outlined below:

•Changes in the fair value of convertible preferred stock warrants liability: We exclude these fair value changes primarily because they are non-cash items and the fair value varies based on the fair value of the underlying preferred stock, varying valuation methodologies and subjective assumptions. Their inclusion makes the comparison of our current financial results to previous and future periods difficult to evaluate.

•Stock-based compensation expense: This consists of expenses for equity awards under our equity incentive plans. Although stock-based compensation is an important aspect of the compensation paid to our employees, the grant date fair value varies based on the stock price at the time of grant, varying valuation methodologies, subjective assumptions and the variety of award types. This makes the comparison of our current financial results to previous and future periods difficult to evaluate; therefore, we believe it is useful to exclude stock-based compensation. We also excluded these expenses because they are non-cash.

74

•Amortization or impairment of acquired intangible assets and impairment of goodwill: We incur amortization or impairment of acquired Intangible Assets and Goodwill in connection with acquisitions and therefore exclude these amounts from our non-GAAP measures. We exclude these items because management does not believe they are reflective of our ongoing operating results.

•Impact of interest rates on the fair value of loans held in consolidated trusts: See discussion on Adjusted Net Revenue, above.

•Accelerated amortization of PWIT debt issuance costs: See discussion on Adjusted Net Revenue, above.

•Interest Expense on Term Loan: We incur interest expense on the Term Loan we closed in November 2022, which is more fully described in Note 11 of the accompanying consolidated financial statements. Proceeds from the Term Loan are used to fund the operations of the business at our discretion, within certain limitations. This may include, but is not limited to, making investments in our Credit Card product, investing in loans held in our warehouse facilities or meeting operational obligations. We exclude the Term Loan interest expense not associated with proceeds used to invest in loans held in our warehouse facilities from Adjusted EBITDA, as it is based on the overall financing structure of PMI. This differs from Interest Expense on Financial Instruments (part of Total Net Revenues), as the proceeds from those instruments are used exclusively for the purposes of purchasing loans on our marketplace.

Adjusted EBITDA	$	3,034	$	(6,337)

The increase in Adjusted EBITDA for the three months ended March 31, 2024, as compared to the corresponding period in 2023, is primarily reflective of increased transaction fees driven by the revised WebBank transaction fee schedule, as well as a significant increase in Credit Card net revenues due to growth in the underlying portfolio since the Credit Card program launched at the end of 2021. This includes the Credit Card Derivative, which drove an increase in the Change in Fair

75

Value of Financial Instruments as compared to the prior year. These were partially offset by the impact of decreased personal loan originations, and increased incentives provided to whole loan investors, as described above.

Expenses on the condensed consolidated statements of operations include the following amounts of stock-based compensation expense for the periods presented (in thousands):

Segment Adjusted EBITDA is our primary segment profitability metric, and is calculated as segment revenue less operating expenses that are directly attributable to the segments’ products. Segment Adjusted Net Revenue is calculated as segment revenue less the impact of changes in interest rates on the fair value of loans held in consolidated trusts and certain unusual or infrequent transactions. For the periods presented above, these adjustments only impact the Personal Loan segment.

76

Personal Loan

For the three months ended March 31, 2024, Personal Loan segment net revenues decreased $2.5 million, or 8%, as compared to the corresponding period in 2023, primarily as a result of (a) a $9.1 million decrease from Loss on Sale of Borrower Loans, due primarily to an increase in incentives provided to our whole loan investors during the first quarter of 2024 as compared to the corresponding period in 2023; (b) a $4.6 million decrease in Total Interest Income (Expense), Net, due in part to a decrease in the average outstanding principal balance of loans held in consolidated warehouse and securitization trusts, combined with the impact from increased debt discount and debt issuance cost amortization from the termination of the PWIT Warehouse Line in March 2024 and the PMIT 2023-1 securitization established in September 2023; and (c) a $0.4 million decrease in Servicing Fees, Net, due to the decrease in whole loans outstanding during this period, as discussed above. These decreases were partially offset by (d) a $7.3 million increase in Transaction Fees, Net, due to the revised WebBank transaction fee schedule starting in the fourth quarter of 2023, with some offsetting impact from the lower personal loan origination volume during this time, and (e) a $4.2 million increase in net revenues from Change in Fair Value of Financial Instruments related to Borrower Loans and Loans Held for Sale, as described above.

Segment Adjusted Net Revenue associated with the Personal Loan segment decreased $0.9 million for the three months ended March 31, 2024, as compared to the corresponding period in 2023. This is reflective of the same factors that drove the decrease in net revenues discussed above, excluding the impact of interest rates on the fair value of loans held in consolidated trusts and the accelerated recognition of debt issuance costs upon the termination of the PWIT Warehouse Line in March 2024.

Adjusted EBITDA associated with the Personal Loan segment increased $4.3 million for the three months ended March 31, 2024, as compared to the corresponding period in 2023. This is primarily reflective of a reduction in expenses year-over-year, including personnel, outsourced services and marketing costs, to address the decrease in personal loan originations during this time, partially offset by the factors that drove the decrease in segment Adjusted Net Revenue discussed above.

Home Equity

Home Equity segment net revenues and segment Adjusted Net Revenue remained flat year-over-year. Home Equity segment net revenues consist of broker fees from our lending partners, and Adjusted EBITDA is reflective of these net revenues, offset by operating expenses. Home Equity segment operating expenses decreased $0.9 million year-over-year, as we reduced resources dedicated to the Home Equity segment.

Credit Card

For the three months ended March 31, 2024, Credit Card segment net revenues and Segment Adjusted Net Revenues increased $5.6 million, or 86%, as compared to the corresponding period in 2023, primarily as a result of (a) a $2.4 million increase in Transaction Fees, Net, generally due to the overall growth in our Credit Card portfolio during this time; (b) a $1.7 million increase in fair value gains on our Credit Card Derivative; and (c) a $1.6 million increase in Servicing Fees, Net, driven by fair value gains on our Credit Card servicing obligation. These fair value gains are in turn due to both the overall growth in our Credit Card portfolio during this time, as well as a change in estimate related to the application of a single discount rate to all the components of our Credit Card Derivative and the servicing obligation.

Adjusted EBITDA associated with the Credit Card segment increased $4.2 million, for the three months ended March 31, 2024, as compared to the corresponding period in 2023, which is primarily reflective of the increase in net revenues discussed above, partially offset by our continued investments in the Credit Card product’s growth.

LIQUIDITY AND CAPITAL RESOURCES

We have incurred operating losses in prior periods and may continue to incur net losses in the future. For the three months ended March 31, 2024 and 2023, we recognized a net income of $22.3 million and incurred a net loss of $9.1 million, respectively. Additionally, from our inception through March 31, 2024, we have had an accumulated deficit of $567.8 million

We believe our liquidity needs for the next twelve months, and for the foreseeable future beyond that period, can be met through transaction fees, servicing fees, net interest income, other revenue, proceeds from sales of loans, realized gains on the Credit Card Derivative and Cash and Cash Equivalents. For further details related to our Term Loan and warehouse lines, see Note 11 of the accompanying consolidated financial statements. Management monitors our financial results and operations. If the financial results anticipated are not achieved or we fail to maintain compliance with the debt covenants under our Term Loan, our sources of liquidity may not be sufficient to meet our operating and liquidity requirements without obtaining additional liquidity which may not be available on favorable terms or at all.

Cash, Cash Equivalents and Restricted Cash at the end of the period	$	139,203	$	160,167

Cash, Cash Equivalents and Restricted Cash decreased by $16.1 million for the three months ended March 31, 2024, based on the following components:

Operating Activities: $44.7 million in cash was provided by operating activities, driven by (a) $52.9 million in net proceeds from Loans Held for Sale, partially offset by (b) $7.7 million in cash used for working capital, primarily due to the timing of payments to investors and third-party vendors and (c) $0.5 million in net loss, net of non-cash items.

Investing Activities: $6.1 million in cash was used in investing activities due to (a) $51.9 million in purchases of Borrower Loans, and (b) $3.9 million in purchases of property and equipment, primarily consisting of internal-use software, partially offset by (c) $49.6 million from sales and principal payments of Borrower Loans.

Financing Activities: $54.7 million in cash was used in financing activities, due primarily to (a) $129.4 million paid for the extinguishment of principal on the PWIT Warehouse Line, (b) $28.6 million in principal payments on the PWIT Warehouse Line and (c) $1.7 million in debt issuance costs related to the PMIT 2024-1 securitization executed in March 2024, partially offset by (d) $105.3 million in proceeds, net of payments, from the issuance of our securitization notes.

Cash, Cash Equivalents and Restricted Cash increased $36.4 million for the three months ended March 31, 2023 based on the following components:

Operating Activities: $68.4 million in cash was used in operating activities, driven by (a) $62.0 million in net purchases of Loans Held for Sale, (b) $3.3 million in cash used for working capital, primarily due to the timing of payments to investors and third-party vendors and (c) $3.1 million in net loss, net of non-cash items.

Investing Activities: $21.8 million in cash was used in investing activities due to (a) $63.9 million in purchases of Borrower Loans, and (b) $4.4 million in purchases of property and equipment, primarily consisting of internal-use software, partially offset by (c) $46.4 million from sales and principal payments of Borrower Loans.

Financing Activities: $53.8 million in cash was provided by financing activities, due primarily to (a) $16.4 million in proceeds from issuance, net of payments, on Notes, at Fair Value, and (b) $38.3 million in proceeds from Warehouse Lines, partially offset by (c) $0.9 million in debt issuance costs related to the extension of our PWIIT warehouse facility in February 2023 (Note 10).

Income Taxes

We use the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized by applying the statutory tax rates in effect in the years in which the differences between the financial reporting and tax filing bases of existing assets and liabilities are expected to reverse. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance against our deferred tax assets. Based on the weight of available evidence, which includes our historical operating performance and the reported cumulative net losses in prior years, we have provided a full valuation allowance against our net deferred tax assets.

We report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. We are required to make subjective assumptions and judgments regarding our income tax exposures. Interpretations and guidance surrounding income tax laws and regulations change over time. As such, changes in our subjective assumptions and judgments can materially affect amounts recognized in the consolidated balance sheets and statements of operations.

78

Off-Balance Sheet Arrangements

As a result of retaining servicing rights on the sale of Borrower Loans, we are an interest holder in certain special purpose entities that purchase these Borrower Loans. None of these special purpose entities are consolidated as we are not the primary beneficiary. Other than these special purpose entities, as of March 31, 2024, we did not have any relationships with unconsolidated entities or financial partnerships, such as structured finance or special purpose entities that were established for the purpose of facilitating off-balance sheet arrangements or other purposes.

CRITICAL ACCOUNTING POLICIES

Certain of Prosper's accounting policies that involve a higher degree of judgment and complexity are discussed in Part II, Item 7, “Management's Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates” in Prosper’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no significant changes to our critical accounting estimates during the first three months of 2024, other than the following changes to our Valuation of Credit Card Derivative and Credit Card Servicing Obligation estimates.

Effective March 31, 2024, we applied a single discount rate to all of the projected cash flows that comprise the Credit Card Derivative and Credit Card servicing obligation liability, in order to better align with how we believe a market participant would estimate the fair value of those cash flows. This single discount rate reflects the expected market rate of return from an investment in residual cash flows derived from a credit card portfolio. Previously, separate discount rates were applied to different cash flows reflecting assumptions around counterparty credit risk. The effect of this change in estimate increased the Credit Card Derivative by $7.3 million and reduced the Credit Card servicing obligation by $1.9 million as of March 31, 2024. Accordingly, it increased Total Net Revenue and Net Income by $9.2 million for the three months ended March 31, 2024.

PROSPER FUNDING LLC

Overview

Prosper Funding LLC was formed in the state of Delaware in February 2012 as a limited liability company with PMI as its sole equity member. Prosper Funding was formed by PMI to hold Borrower Loans originated through the Note Channel and issue related Notes. Although Prosper Funding is consolidated with PMI for accounting and tax purposes, Prosper Funding has been organized and is operated in a manner that is intended to minimize the likelihood that it would be substantively consolidated with PMI in a bankruptcy proceeding. Prosper Funding’s intention is to minimize the likelihood that its assets would be subject to claims by PMI’s creditors if PMI were to file for bankruptcy, as well as to minimize the likelihood that Prosper Funding will become subject to bankruptcy proceedings directly. Prosper Funding seeks to achieve this by placing certain restrictions on its activities and by implementing certain formal procedures designed to expressly reinforce its status as a distinct corporate entity from PMI.

As a credit marketplace, we believe our customers are more highly susceptible to uncertainties and negative trends, real or perceived, in the markets driven by, among other factors, general economic conditions in the United States and abroad. These external economic conditions and resulting trends or uncertainties could adversely impact our customers’ ability or desire to participate in our marketplace as borrowers or investors, and consequently could negatively affect our business and results of operations.

Results of Operations

Overview

The following tables summarize Prosper Funding’s net (loss) income for the three months ended March 31, 2024 and 2023 (in thousands):

	Three Months Ended March 31,
	2024		2023		$ Change		% Change
Total Net Revenues	$	14,830	$	17,240	$	(2,410)	(14)	%
Total Expenses	18,014		16,983		1,031		6	%
Net Income	$	(3,184)	$	257	$	(3,441)	n/m

n/m: not meaningful

Total net revenues for the three months ended March 31, 2024 decreased $2.4 million, or 14%, from the three months ended March 31, 2023, primarily due to an increase in Loss on Sale of Borrower Loans, mainly as a result of additional incentives provided to whole loan investors (“incentives”), combined with the impact from the decrease in the volume of whole loans sold due to lower personal loan originations. Because of the lower servicing book there was a resulting decrease in Servicing Fees, Net. Finally, the decrease in net revenues from Change in Fair Value of Financial Instruments, Net for the three months ended March 31, 2024, compared to corresponding period of 2023, is primarily reflective of the timing of the issuance of Borrower Loans and collections on Notes, at Fair Value near quarter-end. This includes the impact of Borrower Loans transferred to PFL in conjunction with the PMIT 2024-1 Transaction, as discussed in Note 4, Borrower Loans and Notes, at Fair Value, of the accompanying condensed consolidated financial statements. These decreases were partially offset by an increase in administration fee revenue driven by an increase in reimbursements received from PMI for incentives provided to whole loan investors, which was partially offset by a decrease in loan listings generated on the marketplace.

Total expenses for the three months ended March 31, 2024 increased $1.0 million, or 6%, from the three months ended March 31, 2023, largely due to an increase in administrative fee expense during the period resulting from an increase in estimated transaction fee refunds following our revised pricing schedule with WebBank in the fourth quarter of 2024, partially offset by a decrease in loans funded for the period.

Revenues

The following tables summarize Prosper Funding’s revenue for the three months ended March 31, 2024 and 2023 (in thousands, except percentages):

Administration Fee Revenue - Related Party

We primarily generate revenues through license fees we earn under our Administration Agreement with PMI. The Administration Agreement contains a license we grant to PMI that entitles PMI to use the marketplace for, and in relation to: (i) PMI’s performance of its duties and obligations under the Administration Agreement, and (ii) PMI’s performance of its duties and obligations to WebBank under the Loan Account Program Agreement. The Administration Agreement requires PMI to pay us a monthly license fee that is partially based on the number of personal loan listings posted on the marketplace in that month, as well as a fee based on incentives provided to investors to incentivize the purchase of Borrower Loans from PFL. The increase in Administrative Fee Revenue of $8.3 million for the three months ended March 31, 2024, as compared to the corresponding period in 2023, is primarily due to a $9.5 million increase in reimbursements received from PMI for incentives provided to whole loan investors, this was partially offset by a decrease in loan listings generated on the marketplace, which resulted in a $1.2 million decrease in Administrative Fee Revenue for this period.

Servicing Fees, Net

Investors who purchase Borrower Loans through the Whole Loan Channel typically pay us a servicing fee which is currently set at 1.0% per annum of the outstanding principal balance of the Borrower Loan prior to applying the current payment, plus an additional 0.075% per annum to cover the Loan Trailing Fee. The Servicing Fee compensates us for the costs incurred in servicing the Borrower Loan, including managing payments from borrowers, managing payments to investors and maintaining investors’ account portfolios. We record Servicing Fees from investors as a component of operating revenues when received. We also include any collection fees received, net of collection agency expenses, in Servicing Fees, Net.

The decrease in Servicing Fees, Net of $0.6 million for the three months ended March 31, 2024, respectively, as compared to the corresponding period in 2023, is largely due to the decrease in the servicing book during this period, which resulted in approximately $0.6 million decrease in Servicing Fees. This is generally in line with the decrease in personal loan originations in the period.

Loss on Sale of Borrower Loans

Loss on Sale of Borrower Loans consists of net losses and gains on Borrower Loans sold through the Whole Loan Channel, net of any incentives provided to investors at the time of sale. For the three months ended March 31, 2024, the incentives increased $9.5 million from the corresponding period in the prior year. Excluding the impact of these incentives, the remaining decreases from Loss on Sale of Borrower Loans of $0.4 million for the three months ended March 31, 2024 as compared to the same period in 2023, were primarily due to decreases in the volume of whole loans sold due to lower personal loan originations, as discussed above.

Other Revenues

81

Other Revenues has historically consisted primarily of incentive fees, which are earned from partner companies through our incentive programs. The change in Other Revenues for the three months ended March 31, 2024, as compared to the corresponding period in 2023 was not significant.

Interest Income on Borrower Loans and Interest Expense on Notes

We recognize Interest Income on Borrower Loans using the accrual method based on the stated interest rate to the extent we believe it to be collectible. We record Interest Expense on the corresponding Notes based on the contractual interest rates. The interest rate on Notes is generally 1% lower than the interest rate on the corresponding Borrower Loans to compensate us for servicing the underlying Borrower Loans.

Overall, the $0.1 million decrease in Net Interest Income for the three months ended March 31, 2024, as compared to the corresponding period in 2023, is due to a decrease in the outstanding principal balance of Borrower Loans and Notes during these period.

Change in Fair Value of Financial Instruments

Change in Fair Value of Financial Instruments captures gains (losses) in fair value estimates using discounted cash flow methodologies that are based upon a set of valuation assumptions. The key assumptions used in valuations include default and prepayment rates derived from historical performance and discount rates that reflect estimates of the rates of return that investors would require when investing in other financial instruments with similar characteristics. Changes in fair value of Borrower Loans funded through the Note Channel are largely offset by the changes in fair value of the corresponding Notes due to the borrower payment-dependent structure, though differences will arise due to the actual and projected impact of cash flows related to charge-offs, debt sales and miscellaneous fees.

The following table summarizes the fair value adjustments for the three month periods ended March 31, 2024 and 2023 (in thousands):

	Three Months Ended March 31,
	2024		2023
Borrower Loans	$	(5,558)	$	(7,809)
Notes	4,872		7,429
Total	$	(686)	$	(380)

The decrease in net revenues from Change in Fair Value of Financial Instruments for the three months ended March 31, 2024, as compared to the corresponding period in 2023, is primarily reflective of the timing of the issuance of Notes and collection of Borrower Loan proceeds close to period-end. Other fair value changes are generally not material, which is consistent with the borrower payment-structure described above.

Expenses

The following table summarizes our expenses for the three month periods ended March 31, 2024 and 2023 (in thousands, except percentages):

	Three Months Ended March 31,
	2024		2023		Change		% Change
Expenses:
Administration Fee - Related Party	$	16,128	$	15,242	$	886	6	%
Servicing and Other, Net	1,886		1,741		145		8	%
Total Expenses	$	18,014	$	16,983	$	1,031	6	%

Administration Fee - Related Party

Pursuant to our Administration Agreement with PMI, PMI manages the marketplace on our behalf. Accordingly, each month we are required to pay PMI (a) a corporate administration fee of $500,000 per month, (b) a fee for each Borrower Loan originated through the marketplace, (c) 62.5% of all Servicing Fees collected by us or on our behalf and (d) all nonsufficient funds fees collected by us or on our behalf. In general, the Administrative Fee Expense will not fluctuate directly in line with the Administrative Fee Revenue due to both the flat corporate administrative fee, as well as the fact that we pay fees for three

82

different services, but receive a fee based only on the number of loans listed on the platform. We also include refund liabilities for transaction fees above 5%, based on our revised pricing schedule with WebBank, in Administration Fee - Related Party.

The increase in Administration Fee - Related Party expense of $0.9 million for the three months ended March 31, 2024, as compared to the same period in 2023, is due primarily to a $2.6 million increase in the refund liability for transaction fees above 5%, as we only revised our pricing schedule with WebBank in the fourth quarter of 2024. This was partially offset by a decrease in administration fees of $1.6 million, due to a drop in the number of loans funded during the period, as well as the decrease in Servicing Fees, Net, discussed above.

Servicing and Other, Net

Servicing costs consist primarily of vendor and borrower costs, as well as depreciation of internal-use software associated with servicing Borrower Loans. The increase in Servicing costs for the three months ended March 31, 2024, as compared to the corresponding period in 2023, was primarily driven by the increase in depreciation of internal-use software.

Other costs consist primarily of bank service charges and professional fees. The change in Other costs for the three months ended March 31, 2024, as compared to the corresponding period in 2023 was not significant.

Servicing and Other costs are offset by interest income of $0.3 million and $0.1 million generated from cash invested on our platform during the three months ended March 31, 2024 and 2023, respectively. The increase from the prior year period is primarily related to the change in interest rates.

LIQUIDITY AND CAPITAL RESOURCES

We anticipate that our available funds and cash flow from operations will be sufficient to meet our operational cash needs for at least the next 12 months.

The following table summarizes our cash flow activities for the three months ended March 31, 2024 and 2023 (in thousands):

	Three Months Ended March 31,
	2024		2023
Net (Loss) Income	$	(3,184)	$	257
Net Cash (Used in) Provided by Operating Activities	(9,850)		9,475
Net Cash Used in Investing Activities	(5,090)		(19,777)
Net Cash (Used in) Provided by Financing Activities	(217)		16,360
Net (Decrease) Increase in Cash, Cash Equivalents and Restricted Cash	(15,157)		6,058
Cash, Cash Equivalents and Restricted Cash at the beginning of the period	97,039		97,849
Cash, Cash Equivalents and Restricted Cash at the end of the period	$	81,882	$	103,907

Cash, Cash Equivalents and Restricted Cash decreased $15.2 million for the three months ended March 31, 2024, based on the following components:

Operating Activities: $9.9 million was used in operating activities, driven by cash used in working capital of $9.0 million, primarily due to the timing of payments to PMI and investors, combined with net loss, net of non-cash adjustments of $0.8 million.

Investing Activities: $5.1 million was used in investing activities, due to $51.9 million in purchases of Borrower Loans and $2.9 million in purchases of property and equipment, partially offset by $49.6 million of principal payments under Borrower Loans.

Financing Activities: $0.2 million was used by financing activities, due to $49.8 million in payments for Notes, at Fair Value, partially offset by $49.6 million in proceeds from the issuance of Notes, at Fair Value.

Cash, Cash Equivalents and Restricted Cash increased $6.1 million for the three months ended March 31, 2023, based on the following components:

Operating Activities: $9.5 million was provided by operating activities, driven by cash provided by working capital of $7.8 million, primarily due to the timing of payments to PMI and investors, and net income, net of non-cash adjustments of $1.6 million.

83

Investing Activities: $19.8 million was used in investing activities, due to $63.9 million in purchases of Borrower Loans and $2.4 million in purchases of property and equipment, partially offset by $46.5 million of principal payments under Borrower Loans.

Financing Activities: $16.4 million was provided by financing activities, due to $62.6 million in proceeds from the issuance of Notes, at Fair Value, partially offset by $46.3 million in payments for Notes, at Fair Value.

Income Taxes

We incurred no income tax expense for the three months ended March 31, 2024 and 2023. We are a US disregarded entity for income tax purposes and our income and loss is included in the return of our parent, PMI. Given PMI’s history of taxable losses, it is difficult to accurately forecast how Prosper’s and our results will be affected by the realization and use of net operating loss carry forwards.

Off-Balance Sheet Arrangements

As a result of retaining servicing rights on the sale of Borrower Loans, we are a variable interest holder in certain special purposes entities that purchase these Borrower Loans. None of these special interest entities are consolidated as we are not the primary beneficiary. Otherwise as of March 31, 2024, we have not engaged in any off-balance sheet financing activities.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK AND INTEREST RATE RISK

PROSPER MARKETPLACE, INC.

Market Risk

Market risk is the risk of loss to future earnings, values, or future cash flows that may result from changes in financial market prices and interest rates.

Through our securitization trusts (formed in September 2023 and March 2024) we hold Borrower Loans. Changes in U.S. interest rates affect the market value of these Borrower Loans on our balance sheet. Our future investment income may fall short of expectations, or we may suffer a loss in principal if we are forced to sell Borrower Loans that have declined in market value due to changes in interest rates, loss assumptions or overall market conditions. Recent interest rate increases, due in part to ongoing inflation, may increase the risks of our investments in Borrower Loans through our securitization trusts, and additional fluctuations in interest rates may exacerbate such risks. Changes in the market value of Borrower Loans are recorded on the consolidated statements of operations. The fair value of Borrower Loans held in consolidated securitization trusts was $321.8 million as of March 31, 2024.

The fair values of Borrower Loans and Notes are determined using discounted cash flow methodologies based upon a set of valuation assumptions such as default rate, prepayment rate and discount rate. Default rate, prepayment rate and discount rate may change due to expected loan performance or changes in the expected returns of similar financial instruments available in the market. We are exposed to the risk of a decrease in the fair value of loans held in the warehouse and securitization trusts. For Borrower Loans and Notes presented on our Balance Sheet on behalf of our Note Channel investors, the fair value adjustments for Borrower Loans are largely offset by the fair value adjustments of the Notes due to the borrower payment dependent design of the Notes and due to the total principal balances of the Borrower Loans being very close to the total principal balances of the Notes.

We had cash and cash equivalents of $30.3 million and $35.0 million as of March 31, 2024, and December 31, 2023, respectively. These amounts were held in various unrestricted deposits with highly rated financial institutions and short-term, highly liquid marketable securities which may include money market funds, U.S. Treasury securities, and U.S. agency securities. Cash and Cash Equivalents are held for working capital purposes. Due to their short-term nature, we believe that we do not have any material exposure to changes in the fair value of these liquid investments as a result of changes in interest rates. Decreases in short-term interest rates will moderately reduce interest income on these Cash and Cash Equivalents. Increases in short-term interest rates will moderately increase the interest income earned on the Cash and Cash Equivalents.

Interest Rate Sensitivity

As more fully described in Note 8, Fair Value of Assets and Liabilities, of Prosper's condensed consolidated financial statements attached to this Quarterly Report on Form 10-Q, the combined fair value of Borrower Loans and Loans Held for Sale is $644.2 million as of March 31, 2024, determined using a weighted-average discount rate of 7.59%. The combined fair value of Borrower Loans and Loans Held for Sale was $706.5 million as of December 31, 2023, determined using a weighted-

84

average discount rate of 6.88%. A hypothetical 100 basis point increase in interest rates would result in a decrease of approximately $6.1 million and $6.8 million in the fair value of PMI’s investment in Borrower Loans and Loans Held for Sale as of March 31, 2024, and December 31, 2023, respectively. A hypothetical 100 basis point decrease in interest rates would result in an increase of approximately $6.3 million and $6.9 million in the fair value of our investment in Borrower Loans and Loans Held for Sale as of March 31, 2024, and December 31, 2023, respectively. Any realized or unrealized gains or losses resulting from such interest rate change would be recorded in our statement of operations so long as we hold these Borrower Loans and Loans Held for Sale on our balance sheet.

PROSPER FUNDING LLC

Market Risk

Market risk is the risk of loss to future earnings, values, or future cash flows that may result from changes in financial market prices and interest rates.

Because balances, interest rates, and maturities of Borrower Loans are matched and offset by an equal balance of Notes with the exact same interest rates (net of our servicing fee) and initial maturities, we believe that we do not have any material exposure to changes in the net fair value of the combined Borrower Loan and Note portfolios as a result of changes in interest rates. We do not hold or issue financial instruments for trading purposes.

The fair values of Borrower Loans and the related Notes are determined using discounted cash flow methodologies based upon a set of valuation assumptions. The fair value adjustments for Borrower Loans are largely offset by the fair value adjustments of the Notes due to the borrower payment dependent design of the Notes and due to the total principal balances of the Borrower Loans being very close to the total principal balances of the Notes.

Prosper Funding had Cash and Cash Equivalents of $2.2 million as of March 31, 2024, and $3.4 million as of December 31, 2023. These amounts were held in various unrestricted deposits with highly rated financial institutions and short term, highly liquid marketable securities which may include money market funds, U.S. treasury securities and U.S. agency securities. Cash and cash equivalents are held for working capital purposes. Due to their short-term nature, Prosper Funding believes that it does not have any material exposure to changes in the fair value of these liquid investments as a result of changes in interest rates. Decreases in short-term interest rates will moderately reduce interest income on these cash and cash equivalents, while increases in short-term interest rates will moderately increase the interest income earned on these cash and cash equivalent balances.

The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and disclosure requirements for interim financial information and the requirements of Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2023. The balance sheet at December 31, 2023 has been derived from the audited financial statements at that date. Management believes these unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

PMI did not have any items of other comprehensive income or loss for any of the periods presented in the condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023.

The preparation of Prosper’s condensed consolidated financial statements and related disclosures in conformity with US GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in Prosper’s financial statements and accompanying notes. Management bases its estimates on historical experience and on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities. These judgments, estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions.

The accompanying interim condensed consolidated financial statements include the accounts of PMI, its wholly-owned subsidiaries and consolidated VIEs. All intercompany balances have been eliminated in consolidation.

Notes Issued by Securitization Trust are notes held by certain third-party investors pursuant to Prosper’s securitization transactions, and are distinguishable from the borrower payment dependent Notes available to investors through the Company’s Note Channel.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Prosper’s significant accounting policies are included in Note 2, Summary of Significant Accounting Policies, in Prosper’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no changes to these accounting policies during the first three months of 2024.

Fair Value Measurements

Financial instruments measured at fair value consist principally of Borrower Loans (Note 4), Loans Held for Sale (Note 4), Servicing Assets (Note 6), Credit Card Derivative (Note 5), Loan Trailing Fee Liabilities (Note 10), Debt (Note 11) and Convertible Preferred Stock Warrant Liability (Note 13). The estimated fair values of other financial instruments, including Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable and Accrued Liabilities, and Payable to Investors approximate their carrying values because of their short-term nature. The estimated fair values of the Term Loan and Warehouse Lines (Note 11) do not approximate their carrying values due primarily to differences in the stated and market rates associated with these instruments.

Refer to Note 8, Fair Value of Assets and Liabilities, for additional fair value disclosures.

Restricted Cash

Restricted cash consists primarily of cash deposits, money market funds and short-term certificate of deposit accounts held as collateral as required for loan funding and servicing activities, and cash that investors or Prosper have on the marketplace that has not yet been invested in Borrower Loans or disbursed to the investor.

Borrower Loans, Loans Held for Sale and Notes

Borrower Loans are funded either through the Note Channel or through the Whole Loan Channel. Through the Note Channel, Prosper purchases Borrower Loans from WebBank, then issues Notes and holds the Borrower Loans until maturity. The obligation to repay a series of Notes issued through the Note Channel is dependent upon the repayment of the associated Borrower Loan. Borrower Loans funded and Notes issued through the Note Channel are carried on Prosper’s condensed consolidated balance sheets as assets and liabilities, respectively.

Until March 2024, Prosper used Warehouse Lines to purchase Loans Held for Sale that could be subsequently contributed to securitization transactions or sold to investors. Loans Held for Sale were included in “Loans Held for Sale, at Fair Value” on the condensed consolidated balance sheets. In September 2023 and March 2024, in connection with the securitization transactions discussed below, the Loans Held for Sale in these Warehouse Lines were fully contributed to the securitization entities or purchased by Prosper, and the outstanding balances of the Warehouse Lines were fully paid down. See Note 11, Debt for more details on the termination of the Warehouse Lines.

In September 2023 and March 2024, Prosper closed two separate securitization transactions, PMIT 2023-1 and PMIT 2024-1, respectively, with personal loans previously funded through its PWIIT Warehouse Line and PWIT Warehouse Line, respectively. These newly formed securitization entities issued notes acquired by third parties and residual certificates acquired by PMI (a majority owned affiliate of PFL, the sole sponsor of the securitizations). PMIT 2023-1 and PMIT 2024-1 are deemed consolidated VIEs, and as a result the Borrower Loans they hold are presented in “Borrower Loans, at Fair Value,” and the notes sold to third-party investors are included in “Notes Issued by Securitization Trust” on the accompanying condensed consolidated balance sheets. See Note 7, Securitizations, for additional disclosures related to these securitizations.

Borrower Loans and Loans Held for Sale are purchased from WebBank. Prosper places Borrower Loans and Loans Held for Sale on non-accrual status when they are 120 days past due. When a loan is placed on non-accrual status, Prosper stops accruing interest and reverses all accrued but unpaid interest as of such date. Additionally, Prosper charges-off Borrower Loans and Loans Held for Sale when they are 120 days past due. The fair value of loans 120 or more days past due generally consists of the expected recovery from debt sales in subsequent periods.

Prosper has elected the fair value option for Borrower Loans, Loans Held for Sale and Notes. Changes in the fair value of Borrower Loans funded through the Note Channel are largely offset by the changes in fair value of Notes due to the borrower payment-dependent design of the Notes. Changes in the fair value of Borrower Loans and Loans Held for Sale are recorded through Proper's earnings and Prosper collects interest on Borrower Loans and Loans Held for Sale. Changes in the fair values of Borrower Loans, Loans Held for Sale and Notes are included in “Change in Fair Value of Financial Instruments” on the accompanying condensed consolidated statements of operations.

Prosper primarily uses a discounted cash flow model to estimate the fair value of Borrower Loans, Loans Held for Sale and Notes. The key assumptions used in the valuation include default rates and prepayment rates derived primarily from historical performance, and discount rates based on estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

Credit Card Derivative

The Company evaluated the terms of its Credit Card program agreement (the “Credit Card Program Agreement”) with Coastal Community Bank (“Coastal”) and determined that it contained features that met the definition of derivatives under Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging. These features are freestanding financial instruments (as defined under ASC 480, Distinguishing Liabilities from Equity), and have been valued separately as derivatives. A right of offset exists between the derivatives, and they are presented net on the accompanying consolidated balance sheets. Changes in the fair value of the Credit Card Derivative, as well as settled transactions from the Credit Card portfolio, are recorded in “Change in Fair Value of Financial Instruments” on the accompanying condensed consolidated statements of operations.

Refer to Note 5, Credit Card, for additional details on revenues and expenses related to the Credit Card product, and to Note 8, Fair Value of Assets and Liabilities, for additional details related to the valuation methodology for the Credit Card Derivative.

Term Loan

Prosper entered into a Credit Agreement, which provided for a Term Loan with a third-party financial institution in November 2022, which is more fully described in Note 11, Debt. This Term Loan is carried at amortized cost, net of discounts and issuance costs, which are subsequently amortized to Interest Expense on Term Loan over the life of the underlying agreement.

Interest Expense on Term Loan is presented as a component of Expenses on the accompanying condensed consolidated statements of operations, except for any portion associated with Term Loan proceeds used to purchase Loans Held for Sale through the Company’s Warehouse Lines, which is presented in “Interest Expense on Financial Instruments” as a component of Net Interest Income on the accompanying condensed consolidated statement of operations.

Leases

Management determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and operating lease liabilities are included on the Condensed Consolidated Balance Sheets in Property and Equipment, Net and in Other Liabilities, respectively. For certain leases with original terms of twelve months or less, PMI recognizes the lease expense as incurred and does not record ROU assets and lease liabilities.

If a contract contains a lease, management evaluates whether it should be classified as an operating or finance lease. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. As most of PMI's leases do not provide an implicit rate, management uses an incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The operating lease ROU assets are evaluated for impairment utilizing the same impairment model used for Property and Equipment.

Consolidation of Variable Interest Entities

The determination of whether to consolidate a VIE in which we have a variable interest requires a significant amount of analysis and judgment regarding whether we are the primary beneficiary of a VIE due to our holding a controlling financial interest in the VIE. A controlling financial interest in a VIE exists if we have both the power to direct the VIE’s activities that most significantly affect the VIE’s economic performance and a potentially significant economic interest in the VIE. The determination of whether an entity is a VIE considers factors, such as (i) whether the entity’s equity investment at risk is insufficient to allow the entity to finance its activities without additional subordinated financial support and (ii) whether a holder’s equity investment at risk lacks any of the following characteristics of a controlling financial interest: the direct or indirect ability through voting rights or similar rights to make decisions about a legal entity’s activities that have a significant effect on the entity’s success, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the legal entity.

Management regularly reviews and reconsiders its previous conclusions regarding the status of an entity as a VIE and whether we are required to consolidate or deconsolidate such VIE in the consolidated financial statements.

Recent Accounting Pronouncements

Accounting Standards Issued, to be Adopted by the Company in Future Periods

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Reference Rate Reform (Topic 848),” which provides optional expedients and exceptions for applying GAAP on contract modifications and hedge accounting, in order to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative referenced rates, such as the Secured Overnight Financing Rate. The optional guidance, which became effective on March 12, 2020, could be applied through December 31, 2022. In December 2022, the FASB issued No 2022-06 extending the sunset date of the relief provided under ASU No. 2020-04 to December 31, 2024. The Company amended its agreements and transitioned to SOFR for contracts that previously referenced LIBOR. The Company continues to evaluate potential future impacts that may result from the discontinuation of LIBOR or other reference rates as well as the accounting provided in this update on our financial condition, results of operations, and cash flows.

In October 2023, the FASB issued ASU No. 2023-06, “Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission’s Disclosure Update and Simplification Initiative”. The amendments in this update modify the disclosure or presentation requirements of a variety of Topics in the ASC in response to the SEC’s Release No. 33-10532, “Disclosure Update and Simplification Initiative”, and align the ASC’s requirements with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective. Early adoption is prohibited. The Company does not expect the adoption of this ASU to have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which updates reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which enhances effective tax rate reconciliation disclosure requirements and provides clarity to the disclosures of income taxes paid, income before taxes and provision for income taxes. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this update should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Other recent accounting pronouncements issued by the FASB did not, or are not believed by management to, have a material impact on the Company’s present or future financial statements.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

PFL's significant accounting policies are included in Note 2, Summary of Significant Accounting Policies, in PFL’s Annual Report on Form 10-K for the year ended December 31, 2023. There have been no changes to these accounting policies during the first three months of 2024.

Fair Value Measurements

Financial instruments consist principally of Cash and Cash Equivalents, Restricted Cash, Borrower Loans, Loans Held for Sale, Accounts Receivable, Accounts Payable and Accrued Liabilities, Payable to Investors and Notes. The estimated fair values of Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable and Accrued Liabilities, and Payable to Investors approximate their carrying values because of their short-term nature.

Refer to Note 7 for additional fair value disclosures.

Restricted Cash

Restricted Cash consists primarily of cash deposits, money market funds and short-term certificate of deposit accounts held as collateral as required for long term leases, loan funding and servicing activities, and cash that investors have on our marketplace that has not yet been invested in Borrower Loans or disbursed to the investor.

Borrower Loans, Loans Held for Sale and Notes

With respect to the Note Channel, PFL purchases Borrower Loans from WebBank, then issues Notes and holds the Borrower Loans until maturity. The obligation to repay a series of Notes funded through the Note Channel is dependent upon the repayment of the associated Borrower Loan. Borrower Loans and Notes funded through the Note Channel are carried on PFL’s condensed consolidated balance sheets as assets and liabilities, respectively.

PFL places Borrower Loans and Loans Held for Sale on non-accrual status when they are 120 days past due. When a loan is placed on non-accrual status, PFL stops accruing interest and reverses all accrued but unpaid interest as of such date. Additionally, PFL charges-off Borrower Loans and Loans Held for Sale when they are 120 days past due. The fair value of loans 120 days past due generally consists of the expected recovery from debt sales in subsequent periods.

Management has elected the fair value option for Borrower Loans, Loans Held for Sale, and Notes. Changes in fair value of Borrower Loans are largely offset by the changes in fair value of Notes due to the borrower payment-dependent design of the Notes. Changes in fair value of Borrower Loans, Loans Held for Sale and Notes are included in “Change in Fair Value of Financial Instruments, Net” on the condensed consolidated statements of operations.

PFL primarily uses a discounted cash flow model to estimate the fair value of Borrower Loans, Loans Held for Sale and Notes. The key assumptions used in the valuation include default rates and prepayment rates derived primarily from historical performance and discount rates based on estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

Credit Card

Credit Card

In March 2024, the Company executed an amendment to the Credit Card Program Agreement that revised the allocation of customer accounts designated as Prosper accounts (“Prosper Allocations”) and Coastal accounts (“Coastal Allocations”) from 90% and 10%, respectively, to 95% and 5%, respectively. Additionally, the maximum outstanding Credit Card principal balance for Prosper Allocations was increased from $300 million to $350 million. These changes went into effect on April 1, 2024.

For the three months ended March 31, 2024 and 2023, the Company recognized $9.1 million and $6.1 million, respectively, of unrealized gains from fair value changes on the Credit Card Derivative. Changes from settled transactions underlying the Credit Card Derivative, including income from debt sales on charged off balances, were a loss of $2.7 million and a loss of $1.5 million for the three months ended March 31, 2024 and 2023, respectively. These unrealized and settled gains and losses are included in Changes in Fair Value of Financial Instruments on the accompanying condensed consolidated statements of operations.

The Company records revenue from various fees generated from the Credit Card program, including interchange fees, annual fees and late fees, net of a portion of the interchange fees that must be remitted to Coastal. These fees are included in

Transaction Fees, Net on the accompanying condensed consolidated statements of operations. For the three months ended March 31, 2024 and 2023, these fees totaled $5.8 million and $3.4 million, respectively.

Under the program agreement, Prosper is responsible for servicing the entire underlying Credit Card portfolio. Coastal pays the Company a 1% per annum servicing fee on the daily outstanding principal balance of receivables designated as Coastal Allocations. To the extent these servicing fees do not exceed the market servicing rate a market participant would require to service the entire Credit Card portfolio, the Company records a servicing obligation liability and measures it at fair value through the servicing period. The net balance of this servicing obligation liability is included in “Other Liabilities” on the accompanying condensed consolidated balance sheets (see Note 10, Other Liabilities). Changes in the fair value of the servicing obligation liability are recorded in Servicing Fees, Net on the accompanying condensed consolidated statements of operations, and totaled a gain of $0.9 million and a loss of $0.9 million for the three months ended March 31, 2024 and 2023, respectively

Prosper accounts for Servicing Assets at their estimated fair values with changes in fair values recorded in Servicing Fees, Net on the accompanying condensed consolidated statement of operations. The initial asset or liability is recognized when Prosper sells Borrower Loans to unrelated third-party buyers through the Whole Loan Channel and the servicing rights are retained. The Servicing Assets are measured at fair value throughout the servicing period. The Company recognized a loss on the sale of such Borrower Loans in the amount of $10.5 million and $1.4 million for the three months ended March 31, 2024 and 2023, respectively, recorded in (Loss) Gain on Sale of Borrower Loans on the condensed consolidated statements of operations.

As of March 31, 2024, Borrower Loans that were sold but for which Prosper retained servicing rights had a total outstanding principal balance of $3.1 billion, original terms to maturity of 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and various original maturity dates through March 2029. As of December 31, 2023, Borrower Loans that were sold but for which Prosper retained servicing rights had a total outstanding principal balance of $3.1 billion, original terms to maturity of either 24, 36, 48 or 60 months, monthly payments with fixed interest rates ranging from 5.46% to 33.00%, and various original maturity dates through December 2028.

Contractually-specified servicing fees and ancillary fees totaling $7.4 million and $8.2 million for the three months ended March 31, 2024 and 2023, respectively, are included in the condensed consolidated statements of operations in Servicing Fees, Net.

Fair Value Valuation Method

Prosper uses a discounted cash flow valuation methodology generally consisting of developing an estimate of future cash flows that are expected to occur over the life of a financial instrument and then discounts those cash flows at a rate of return that results in the fair value amount.

Significant unobservable inputs presented in the table within Note 8 below are those that Prosper considers significant to the estimated fair values of the Level 3 Servicing Assets. The following is a description of the significant unobservable inputs provided in the table.

Market Servicing Rate

Prosper estimates adequate market servicing rates that would fairly compensate a substitute servicer should one be required, which includes the profit that would be demanded in the marketplace. This rate is stated as a fixed percentage of outstanding principal balance on a per annum basis. With the assistance of a valuation specialist, Prosper estimates these market servicing rates based on observable market rates for other loan types in the industry and bids from subservicing providers, adjusted for the unique loan attributes that are present in the specific loans that Prosper sells and services and information from backup service providers.

Discount Rate

The discount rate is a rate of return used to discount future expected cash flows to arrive at a present value, which represents the fair value of the loan servicing rights. We use a range of discount rates for the Servicing Assets based on comparable observed valuations of similar assets and publicly available disclosures related to servicing valuations, with comparability adjustments made to account for differences with Prosper’s servicing assets.

Default Rate

The default rate presented in Note 8 is an annualized, average estimate considering all Borrower Loan categories (i.e., risk ratings and duration), and represents an aggregate of conditional default rate curves for each credit grade or Borrower Loan

category. Each point on a particular Borrower Loan category’s curve represents the percentage of principal expected to default per period based on the term and age of the underlying Borrower Loans. The assumption regarding defaults directly reduces servicing revenues because the amount of servicing revenues received is based on the amount collected each period.

Prepayment Rate

The prepayment rate presented in Note 8 is an annualized, average estimate considering all Borrower Loan categories (i.e., risk ratings and duration), and represents an aggregate of conditional prepayment rate curves for each credit grade or Borrower Loan category. Each point on a particular Borrower Loan category’s curve represents the percentage of principal expected to prepay per period based on the term and age of the underlying Borrower Loans. Prepayments reduce servicing revenues as they shorten the period over which we expect to collect fees on the Borrower Loans, which is used to project future servicing revenues.

PFL estimates adequate market servicing rates that would fairly compensate a substitute servicer should one be required, which includes the profit that would be demanded in the marketplace.

servicing rates based on observable market rates for other loan types in the industry and bids from sub-servicing providers, adjusted for the unique loan attributes that are present in the specific loans that PFL sells and services and information from backup service providers.

Discount Rate

The discount rate is a rate of return used to discount future expected cash flows to arrive at a present value, which represents the fair value of the loan servicing rights. Management used a range of discount rates for the Servicing Assets based on comparable observed valuations of similar assets and publicly available disclosures related to servicing valuations, with comparability adjustments made to account for differences with PFL’s Servicing Assets.

Securitizations

Transfers and Servicing [Abstract]

Securitizations

Securitizations

Prosper served as the sole sponsor of two securitizations of unsecured personal whole loans facilitated through the Company’s marketplace that were previously held in consolidated warehouse trusts: PMIT 2023-1 in September 2023 and PMIT 2024-1 in March 2024, respectively. These transactions benefit the Company by reducing the financing costs associated with the underlying Borrower Loans. Both securitizations issued senior notes and residual certificates to finance the purchase of Borrower Loans. The notes were sold to third-party investors and a majority-owned affiliate of the sole sponsor of the securitizations, PFL, retained the residual certificates. In addition to the residual certificates, Prosper’s continued involvement includes loan servicing responsibilities over the life of the underlying loans.

PMIT 2023-1 and PMIT 2024-1 (together, the “PMITs”) are deemed VIEs, and the Company consolidates them as the primary beneficiary. Through Prosper’s role as the servicer, it has the power to direct the activities that most significantly affect the PMITs’ economic performance. Additionally, because the Company holds the residual certificates, it has a variable interest that could potentially be significant to the PMITs. In evaluating whether Prosper is the primary beneficiary, management considers both qualitative and quantitative factors regarding the nature, size and form of the Company’s involvement with the PMITs. Management assesses whether Prosper is the primary beneficiary of the PMITs on an on-going basis. For the PMITs, the creditors have no recourse to the general credit of Prosper and the liabilities of the PMITs can only be settled by their respective assets. Additionally, the assets of the PMITs can be used only to settle obligations of the PMITs. Because Prosper consolidates the PMITs’ securitization trusts, the Borrower Loans held in those trusts are included in “Borrower Loans, at Fair Value,” and the notes sold to third-party investors are presented in “Notes Issued by Securitization Trust” on the condensed consolidated balance sheets. Because Prosper holds 100% of the residual certificates issued by the PMITs, they eliminate through consolidation and are thus not presented on the condensed consolidated balance sheets.

PMIT 2023-1

In September 2023, Prosper closed the PMIT 2023-1 securitization. Based on the terms of the underlying agreements, the PWIIT Warehouse Line (see Note 11, Debt) agreed to contribute Borrower Loans with an aggregate outstanding principal balance of $275.9 million as of the established cutoff date of August 31, 2023, to the PMIT 2023-1 securitization. On September 25, 2023, these Borrower Loans, with an updated aggregate outstanding principal balance of $266.1 million, were contributed to the PMIT 2023-1 securitization.

The notes under PMIT 2023-1 were issued in five classes: Class A in the amount of $165.5 million, Class B in the amount of $25.4 million, Class C in the amount of $25.1 million, Class D in the amount of $22.3 million and Class E in the amount of $13.1 million (collectively, the “2023-1 Notes”). The Class A, Class B, Class C, Class D and Class E notes bear interest at fixed rates of 7.06%, 7.48%, 8.29%, 11.24% and 15.49%, respectively. Principal and interest payments began in October 2023 and are payable monthly. The 2023-1 Notes are recorded at amortized cost, net of original issue discounts totaling approximately $0.8 million. These discounts, along with debt issuance costs incurred of $2.7 million, are deferred and amortized into interest expense over the contractual lives of the 2023-1 Notes using the effective interest method. As of March 31, 2024, the outstanding principal and accrued interest of the 2023-1 Notes was $186.2 million, secured by an aggregate outstanding principal balance of $196.5 million of borrower loans, and approximately $13.5 million in cash collections held in collateral and reserve accounts included in “Restricted Cash” on the condensed consolidated balance sheets.

PMIT 2024-1

In March 2024, Prosper closed the PMIT 2024-1 securitization. Based on the terms of the underlying agreements, the PWIT Warehouse Line (see Note 11, Debt) agreed to contribute Borrower Loans with an aggregate outstanding principal balance of $148.9 million as of the established cutoff date of February 14, 2024, to the PMIT 2024-1 securitization. On March

28, 2024, these Borrower Loans, with an updated aggregate outstanding principal balance of $138.0 million, were contributed to the PMIT 2024-1 securitization.

The notes under PMIT 2024-1 were issued in four classes: Class A in the amount of $105.2 million, Class B in the amount of $10.8 million, Class C in the amount of $10.3 million and Class D in the amount of $10.2 million (collectively, the “2024-1 Notes”). The Class A, Class B, Class C and Class D notes bear interest at fixed rates of 6.12%, 6.13%, 6.96%, 10.98%, respectively. The 2024-1 Notes are recorded at amortized cost, net of debt issuance costs incurred of $1.5 million. These debt issuance costs are deferred and amortized into interest expense over the contractual lives of the 2024-1 Notes using the effective interest method. As of March 31, 2024, the outstanding principal and accrued interest of the 2024-1 Notes was $136.6 million, secured by an aggregate outstanding principal balance of $137.6 million of borrower loans included in “Borrower Loans, at Fair Value” on the condensed consolidated balance sheets, and approximately $14.1 million in cash collections held in collateral and reserve accounts included in “Restricted Cash” on the condensed consolidated balance sheet

Fair Value of Assets and Liabilities

Fair Value of Assets and Liabilities

Prosper measures the fair value of assets and liabilities in accordance with its fair value hierarchy which prioritizes information used to measure fair value and the effect of fair value measurements on earnings and provides for enhanced disclosures determined by the level within the hierarchy of information used in the valuation. The Company applies this framework whenever other standards require (or permit) assets or liabilities to be measured at fair value.

Assets and liabilities carried at fair value on the balance sheets are classified among three levels based on the observability of the inputs used to determine fair value:

Level 1 — The valuation is based on quoted prices in active markets for identical instruments.

Level 2 — The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation methodologies for which all significant assumptions are observable in the market.

Level 3 — The valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the instrument. Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar methodologies, which incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument or valuations that require significant management judgment or estimation.

Fair values of assets or liabilities are determined based on the fair value hierarchy, which requires an entity to maximize the use of quoted prices and observable inputs and to minimize the use of unobservable inputs when measuring fair value. Various valuation methodologies are utilized, depending on the nature of the financial instrument, including the use of market prices for identical or similar instruments, or discounted cash flow models. When possible, active and observable market data for identical or similar financial instruments are utilized. Alternatively, fair value is determined using assumptions that management believes a market participant would use in pricing the asset or liability.

Financial Instruments Recorded at Fair Value

The fair value of the Borrower Loans, Loans Held for Sale, Notes, Servicing Assets and Liabilities and loan trailing fee liability are estimated using discounted cash flow methodologies based upon a set of valuation assumptions. The primary assumptions used in the discounted cash flow model include default and prepayment rates primarily derived from historical performance and discount rates applied to each credit grade based on the perceived credit risk of each credit grade.

The fair value of the Credit Card Derivative is also estimated using a discounted cash flow model using certain assumptions. The key assumptions used in the valuation include default and prepayment rates derived primarily from historical performance and relevant market data, adjusted as necessary based on the perceived credit risk of the underlying portfolio. In addition, discount rates based on estimates of the rates of return that investors would require when investing in similar credit card portfolios are applied to the individual freestanding derivatives.

The Convertible Preferred Stock Warrant Liability is valued using a Black-Scholes option pricing model. Refer to Note 13 for further details.

The following tables present the fair value hierarchy for assets and liabilities measured at fair value (in thousands):

As PMI’s Borrower Loans, Loans Held for Sale, Notes, Convertible Preferred Stock Warrant Liability, Servicing Assets and Liability, Credit Card Derivative, Credit Card servicing obligation liability and loan trailing fee liability do not trade in an active market with readily observable prices, the Company uses significant unobservable inputs to measure the fair value of these assets and liabilities. Financial instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. These fair value estimates may also include observable, actively quoted components derived from external sources. As a result, gains and losses for assets and liabilities within the Level 3 category may include changes in fair value that were attributable to both observable and unobservable inputs. Prosper did not transfer any assets or liabilities in or out of Level 3 for the three months ended March 31, 2024 and 2023.

Significant Unobservable Inputs

The following tables present quantitative information about the ranges of significant unobservable inputs used for the Company’s Level 3 fair value measurements at March 31, 2024 and December 31, 2023:

	Range
Borrower Loans, Loans Held for Sale and Notes:	March 31, 2024	December 31, 2023
Discount rate	5.4% - 11.1%	5.4% - 8.1%
Default rate	2.9% - 24.3%	3.2% - 23.6%

	Range
Servicing Assets:	March 31, 2024	December 31, 2023
Discount rate	15.0% - 25.0%	15.0% - 25.0%

Market servicing rate (1) (2)	0.633% - 0.842%	0.633% - 0.842%

(1) Servicing assets associated with loans enrolled in a relief program offered by the Company as of March 31, 2024 and December 31, 2023 were measured using a market servicing rate assumption of 84.2 basis points. This rate was estimated using a multiplier consistent with observable market rates for other loan types, applied to the base market servicing rate assumption.

(2) Excludes collection fees that would be passed on to a hypothetical third-party servicer. As of March 31, 2024 and December 31, 2023, the market rate for collection fees and non-sufficient fund fees was assumed to be 6 basis points and 5 basis points, respectively, for a total market servicing rate range of 69.3 - 90.2 basis points and 68.3 - 89.2 basis points, respectively.

	Range
Loan Trailing Fee Liability:	March 31, 2024	December 31, 2023
Discount rate	15.0% - 25.0%	15.0% - 25.0%
Default rate	2.5% - 24.4%	2.8% - 23.6%
Prepayment rate	6.2% - 30.5%	6.1% - 30.6%

Ranges of inputs are not applied to the Credit Card Derivative and Credit Card servicing obligation liability, as they are valued at the portfolio level. Refer below for a summary of the significant unobservable inputs associated with those Level 3 fair value measurements.

At March 31, 2024 and December 31, 2023, the discounted cash flow methodology used to estimate the Notes fair values used the same projected cash flows as the related Borrower Loans.

These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a variation in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects.

Change in Estimate

Effective March 31, 2024, the Company applied a single discount rate to all of the projected cash flows that comprise the Credit Card Derivative and Credit Card servicing obligation liability, in order to better align with how PMI believes a market participant would estimate the fair value of those cash flows. This single discount rate reflects the expected market rate of return from an investment in residual cash flows derived from a credit card portfolio. Previously, separate discount rates were applied to different cash flows reflecting assumptions around counterparty credit risk. The effect of this change in estimate increased the Credit Card Derivative by $7.3 million and reduced the Credit Card servicing obligation by $1.9 million as of March 31, 2024. Accordingly, it increased Total Net Revenue and Net Income by $9.2 million for the three months ended March 31, 2024.

Fair Value of Assets and Liabilities

Fair Value of Assets and Liabilities

PFL has elected to record certain financial instruments at fair value on the balance sheet. PFL classifies Borrower Loans, Loans Held for Sale and Notes as financial instruments and assesses their fair value each on a quarterly basis for financial statement presentation purposes. Gains and losses on these financial instruments are shown separately on the condensed consolidated statements of operations.

As of March 31, 2024 and December 31, 2023, the discounted cash flow methodology used to estimate the Notes fair values used the same projected cash flows as the related Borrower Loans. As demonstrated in the table below, the fair value adjustments for Borrower Loans were largely offset by the fair value adjustments of the Notes due to the borrower payment dependent design of the Notes and because the principal balances of the Borrower Loans approximated the principal balances of the Notes.

Assets and liabilities carried at fair value on the balance sheets are classified among three levels based on the observability of the inputs used to determine fair value:

Level 1 — The valuation is based on quoted prices in active markets for identical instruments.

Level 2 — The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation methodologies for which all significant assumptions are observable in the market.

Level 3 — The valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the instrument. Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar methodologies, which incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument or valuations that require significant management judgment or estimation.

Fair values of assets or liabilities are determined based on the fair value hierarchy, which requires an entity to maximize the use of quoted prices and observable inputs and to minimize the use of unobservable inputs when measuring fair value. Various valuation methodologies are utilized, depending on the nature of the financial instrument, including the use of market prices for identical or similar instruments, or discounted cash flow models. When possible, active and observable market data for identical or similar financial instruments are utilized. Alternatively, fair value is determined using assumptions that management believes a market participant would use in pricing the asset or liability.

Financial Instruments Recorded at Fair Value

The fair value of the Borrower Loans and Notes are estimated using discounted cash flow methodologies based upon a set of valuation assumptions. The primary cash flow assumptions used to value such Borrower Loans and Notes include default and prepayment rates derived primarily from historical performance and discount rates that reflect estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

The following tables present the fair value hierarchy for assets and liabilities measured at fair value (in thousands):

March 31, 2024	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Total

As PFL’s Borrower Loans, Notes, Servicing Assets and loan trailing fee liability do not trade in an active market with readily observable prices, PFL uses significant unobservable inputs to measure the fair value of these assets and liabilities. Financial instruments are categorized in the Level 3 valuation hierarchy based on the significance of unobservable factors in the overall fair value measurement. These fair value estimates may also include observable, actively quoted components derived from external sources. As a result, the realized and unrealized gains and losses for assets and liabilities within the Level 3 category may include changes in fair value that were attributable to both observable and unobservable inputs. PFL did not transfer any assets or liabilities in or out of Level 3 for the three months ended March 31, 2024 or March 31, 2023.

Significant Unobservable Inputs

The following tables present quantitative information about the significant unobservable inputs used for PFL’s Level 3 fair value measurements at the dates presented:

	Range
Borrower Loans and Notes	March 31, 2024	December 31, 2023
Discount rate	5.5% - 8.9%	5.5% - 8%
Default rate	2.9% - 24.0%	3.2% - 23.6%

Market servicing rate (1) (2)	0.633% - 0.842%	0.633% - 0.842%

(1) Servicing assets associated with loans enrolled in a relief program offered by the Company as of March 31, 2024 and December 31, 2023 were measured using a market servicing rate assumption of 84.2 basis points. This rate was estimated using a multiplier consistent with observable market rates for other loan types, applied to the base market servicing rate assumption.

(2) Excludes collection fees that would be passed on to a hypothetical third-party servicer. As of March 31, 2024 and December 31, 2023, the market rate for collection fees and non-sufficient fund fees was assumed to be 6 basis points and 5 basis points, respectively, for a total market servicing rate range of 69.3 - 90.2 basis points and a total market servicing rate of 68.3 - 89.2 basis points, respectively.

Key economic assumptions are used to compute the fair value of Servicing Assets. The sensitivity of the current fair value to immediate changes in assumptions at March 31, 2024 and December 31, 2023 for Servicing Assets are presented in the following table (in thousands, except percentages).

Servicing Assets	March 31, 2024			December 31, 2023

Applying a 0.9 multiplier to default rate	$	14,069		$	14,104

These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a variation in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects.

Debt Disclosure [Abstract]

Debt

Debt

Term Loan

Credit Agreement

On November 14, 2022, the Company entered into a Credit Agreement with a third-party financial institution, which provides for a $75 million Term Loan maturing on November 14, 2026. Proceeds received from the Term Loan were net of an original issue discount and the Company also incurred approximately $0.4 million in debt issuance costs. Both the original issue discount and the debt issuance costs are being amortized over the life of the Term Loan to interest expense using the effective interest method.

Interest

Borrowings under the Term Loan accrue interest at the Secured Overnight Financing Rate (“SOFR”) plus 9.0% per annum. In addition, all borrowings under the Term Loan accrue payment-in-kind (“PIK”) interest at 2.0% per annum. Any accrued PIK interest that remains unpaid at the end of each month is added to the outstanding principal balance of the Term Loan.

Guarantees and Collateral

PMI’s obligations under the Term Loan are guaranteed by PHL and BillGuard. All obligations under the Credit Agreement are secured by a first priority, perfected lien on substantially all of the assets of PMI (subject to exclusions such as certain cash amounts and deposit accounts), PHL and BillGuard, as well as equity interests in all of PMI’s subsidiaries with the exception of PGT.

Covenants and Other Matters

The Credit Agreement contains a number of covenants that, among other things and subject to certain exceptions and thresholds, restrict PMI’s ability to incur certain new indebtedness; incur certain liens; sell or otherwise dispose of all or substantially all its assets; make loans, advances, and guarantees; and pay dividends or make other distributions on equity interests.

In addition, the Credit Agreement contains certain financial covenants with which the Company must remain in compliance as of the last business day of each month during the life of the Term Loan:

•a minimum tangible net worth

•a minimum net liquidity

•a maximum leverage ratio

•a minimum asset coverage ratio

The Company is in compliance with all covenants as of March 31, 2024, as well as applicable monthly periods for the quarter then ended.

The Credit Agreement also contains certain customary representations and warranties and affirmative covenants, and certain reporting obligations. In addition, the Term Loan lender will be permitted to accelerate all outstanding borrowings and exercise other specified remedies upon the occurrence of certain events of default (subject to certain grace periods and exceptions), which include, among other things, payment defaults, breaches of representations and warranties, covenant defaults, certain cross-defaults to other indebtedness, certain events of bankruptcy and insolvency, certain judgments and changes of control.

Prosper Warehouse Trust Agreements

Prosper’s consolidated warehouse VIEs, PWIT and PWIIT (together, the “Warehouse VIEs”), each entered into an agreement (together, the “Warehouse Agreements”) with certain lenders for committed revolving lines of credit (“Warehouse Lines”) during 2018 and 2019, respectively. In connection with the Warehouse Agreements, the Warehouse VIEs each entered into a security agreement with a bank as administrative agent and a national banking association as collateral trustee and paying agent. Proceeds under the Warehouse Lines could only be used to purchase certain unsecured consumer loans and related rights and documents from Prosper and to pay fees and expenses related to the Warehouse Lines. Both Warehouse VIEs are consolidated because Prosper is the primary beneficiary of the VIEs. The assets of the VIEs can be used only to settle obligations of the VIEs. Additionally, the creditors of the Warehouse Lines have no recourse to the general credit of Prosper. The loans held in the Warehouse VIEs are included in Loans Held for Sale, at Fair Value and Warehouse Lines are in Warehouse Lines in the condensed consolidated balance sheets.

Both Warehouse Agreements contained certain covenants including restrictions on each Warehouse VIE's ability to incur indebtedness, pledge assets, merge or consolidate and enter into certain affiliate transactions. Each Warehouse Agreement also required Prosper to maintain a minimum tangible net worth of $25 million, minimum net liquidity of $15 million and a maximum leverage ratio of 5:1. Tangible net worth is defined as the sum of (i) (A) Convertible Preferred Stock, (B) total Stockholders’ Deficit and (C) Convertible Preferred Stock Warrant Liability, less the sum of (ii) (A) goodwill and (B) intangible assets. Net liquidity is defined as the sum of cash, cash equivalents and Available for Sale Investments. The leverage ratio is defined as the ratio of total consolidated indebtedness other than non-recourse securitization indebtedness, non-recourse or limited recourse warehouse indebtedness and borrower dependent notes, to tangible net worth. Through the dates of termination of each Warehouse Line, as discussed below, the Company was not in violation of any of these covenants.

PWIT Warehouse Line

On January 19, 2018, through PWIT, Prosper entered into a Warehouse Agreement for a Warehouse Line with a national banking association for a committed line of credit of $100 million. The PWIT Warehouse Agreement was subsequently amended in June 2018, June 2019, and May 2021, the cumulative impact of which was to increase the committed line of credit to $200 million, adjust the interest rate and unused commitment fee, expand the eligibility criteria for unsecured consumer loans that could be financed through the PWIT Warehouse Line and extend the term of the Warehouse Agreement.

On May 5, 2023, PMI further amended its PWIT Warehouse Line (“PWIT 2023 Extension”). The PWIT 2023 Extension increased the maximum borrowing amount from $200 million to $244 million, consisting of a $200 million Class A loan with the existing PWIT Warehouse Line national banking association and a $44 million Class B loan with an asset manager. Under the PWIT 2023 Extension, the total advance rate was 91.5% and proceeds of loans purchased through the PWIT Warehouse Line could be borrowed, repaid and reborrowed until the earlier of June 20, 2024 or the occurrence of any accelerated amortization event or event of default. Repayment on any outstanding proceeds would be made over a 12-month period ending June 20, 2025, excluding the occurrence of any accelerated amortization event or event of default. Under the PWIT 2023 Extension, the Class A loan bore interest at a rate of one-month SOFR, plus a spread of 2.75% per annum, while the Class B loan bore interest at a rate of one-month SOFR, plus a spread of 8.50% per annum. Additionally, until June 20, 2024, both loans bore a daily unused commitment fee of 0.50% per annum on the undrawn portion available under each respective loan.

In the fourth quarter of 2023, a loan performance ratio under the Warehouse Agreement was exceeded which resulted in the PWIT Warehouse Line entering accelerated amortization. While in accelerated amortization, all loan collections were applied against the outstanding balance of the PWIT Warehouse Line, and the Company was unable to utilize the undrawn portion. In addition, there was a 1% per annum step-up fee on the outstanding balance. On January 22, 2024, the Company executed an amendment to the PWIT Warehouse Agreement, under which previous breaches of loan performance ratios were waived, the loan performance ratios were revised going forward, and the step-up fee was waived until June 30, 2024. Additionally, the advance rate under the PWIT Warehouse Line was to gradually decrease by 1% on a monthly basis through June 2024, until it was reduced to 86.5%.

In conjunction with the PMIT 2024-1 securitization (see Note 7, Securitizations), the entire portfolio of Loans Held for Sale in the PWIT Warehouse Line, with an unpaid principal balance of $142.5 million as of March 28, 2024, was transferred to either the PMIT 2024-1 Transaction or PFL, as follows: $138.0 million of those Borrower Loans were contributed into the securitization trust through a depositor, and the remaining $4.5 million consisted of loans ineligible for securitization and were transferred to PFL through an equity contribution. Proceeds from the sale of these loans were used to pay down the outstanding principal and interest on the PWIT Warehouse Line of $130.4 million, and the PWIT Warehouse line was terminated at that time. Remaining proceeds, net of transaction expenses, following the securitization transaction were transferred to PMI. As a result of the termination of the PWIT Warehouse Line, deferred and unamortized debt issuance costs of $0.7 million were immediately amortized into interest expense.

Prosper maintained a swaption to limit the Company's exposure to increases in SOFR on up to $185.0 million of borrowings under the PWIT Warehouse Line. The swaption was recorded on the consolidated balance sheets at fair value in “Prepaids and Other Assets.” Any changes in the fair value were recorded in the “Change in Fair Value of Financial Instruments” on the condensed consolidated statement of operations. The swaption was terminated on March 28, 2024 upon repayment and termination of the PWIT Warehouse Line in conjunction with the PMIT 2024-1 securitization. The change in fair value of the swaption was immaterial for the three months ended March 31, 2024 and a loss of $0.5 million for the corresponding period in 2023.

PWIIT Warehouse Line

On March 28, 2019, through PWIIT, Prosper entered into a second Warehouse Agreement for a $300 million Warehouse Line with a national banking association different than that of PWIT. Subsequently on March 4, 2021, PMI extended its $300 million PWIIT Warehouse Line (“PWIIT 2021 Extension”). The PWIIT 2021 Extension consisted of a $230 million Class A loan with the existing PWIIT Warehouse Line national banking association and a $70 million Class B loan with an asset manager. On February 10, 2023, PMI again extended its PWIIT Warehouse Line (“PWIIT 2023 Extension”). The PWIIT 2023 Extension increased the maximum borrowing amount from $300 million to $450 million, consisting of a $400 million Class A loan with the existing PWIIT Warehouse Line national banking association and a $50 million Class B loan with the existing asset manager. In May 2023, the Company further amended the PWIIT Warehouse Line, which included replacing the existing Class B lender with another third-party asset manager and lowering the spread on Class B borrowings. In July 2023, the PWIIT Warehouse Line was further amended, decreasing the maximum borrowing amount from $450 million to $300 million, consisting of a $265 million Class A loan and a $35 million Class B loan. The Class A loan bore interest at a per annum rate of the national banking association's asset-backed commercial paper rate, plus a spread of 2.85%, while the Class B loan bore interest a per annum rate of adjusted one-month SOFR, plus a spread of 8.75%.

In conjunction with the PMIT 2023-1 securitization (see Note 7, Securitizations), the entire portfolio of Loans Held for Sale in the PWIIT Warehouse Line, with an unpaid principal balance of $273.8 million as of September 25, 2023, was transferred to either the PMIT 2023-1 securitization or PFL, as follows: $266.1 million of those Borrower Loans were contributed into the securitization trust through a depositor, and the remaining $7.7 million consisted of loans ineligible for securitization and were transferred to PFL through an equity contribution. Proceeds from the sale of these loans were used to pay down the outstanding principal and interest on the PWIIT Warehouse Line of $224.0 million, and the PWIIT Warehouse line was terminated at that time. Remaining proceeds, net of transaction expenses, following the securitization transaction were transferred to PMI. As a result of the termination of the PWIIT Warehouse Line, deferred and unamortized debt issuance costs of $1.9 million were immediately amortized into interest expense.

Net Income (Loss) Per Share

Net Income (Loss) Per Share

PMI computes its net income (loss) per share in accordance with ASC Topic 260, Earnings Per Share (“ASC Topic 260”). Under ASC Topic 260, basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding for the period and excludes the effects of any potentially dilutive securities.

PMI’s net income (loss) per share is calculated using the two-class method in accordance with ASC Topic 260. The two-class method allocates earnings that otherwise would have been available to common shareholders to holders of participating securities. Management considers all series of our Convertible Preferred Stock to be participating securities due to their rights to participate in dividends with Common Stock. As such, earnings allocated to these participating securities, which include participation rights in undistributed earnings, are subtracted from net income to determine total undistributed earnings to be allocated to common stockholders.

All participating securities are excluded from basic weighted-average common shares outstanding. Prior to any conversion to common shares, each series of Prosper’s Convertible Preferred Stock is entitled to participate on an if-converted basis in distributions of earnings, when and if declared by the board of directors, that are made to common stockholders and consequently, these shares were considered participating securities. During the three months ended March 31, 2024 and 2023, certain shares issued as a result of the early exercise of stock options which are subject to a repurchase right by PMI were entitled to receive non-forfeitable dividends during the vesting period and consequently, are considered participating securities.

Convertible Preferred Stock and Warrants

Under PMI’s amended and restated certificate of incorporation, preferred stock is issuable in series, and the Board of Directors is authorized to determine the rights, preferences, and terms of each series.

On July 13, 2020, the Company established Prosper Grantor Trust (“PGT”), a revocable grantor trust administered by an independent trustee, with the intention of contributing assets to PGT for the benefit of PMI employees in the event of a change in control through an Eligible Employee Retention Plan. PGT was determined to be a VIE and PMI was determined to be its primary beneficiary due to the fact that the Company, through its role as the grantor, has both (a) the power to direct the activities that most significantly affect the VIE’s economic performance, including its funding decisions and investment strategy, and (b) the obligation to absorb losses that could be potentially significant to the economic performance of the VIE by virtue of the Company’s requirement to fund PGT in the event that it is unable to meet its obligations to PMI’s employees. PMI also maintains a contingent call liability on PGT’s assets in the event of a bankruptcy. As a result, PGT is fully consolidated into PMI’s consolidated financial statements.

On July 21, 2020, PGT entered into a Stock Transfer Agreement with a PMI investor to purchase 34,670,420 shares of Series A Convertible Preferred Stock and 16,577,495 shares of Series B Convertible Preferred Stock for nominal consideration. Upon execution of the Stock Transfer Agreement, these shares were purchased by a consolidated VIE of the Company, and thus the difference between the fair value of the repurchased stock and the purchase price is included in Convertible Preferred Stock

Held by Consolidated VIE on PMI’s accompanying condensed consolidated balance sheets. These shares remain outstanding for legal purposes and retain their voting rights, but are excluded from the earnings per share calculation.

The number of authorized, issued and outstanding shares, their par value and liquidation preference for each series of convertible preferred stock as of March 31, 2024 are disclosed in the table below (amounts in thousands except share and par value amounts):

Convertible Preferred Stock	Par Value		Authorized Shares	Outstanding and Issued Shares		Liquidation Preference, Outstanding Shares

* Series A and Series B Convertible Preferred Stock totals are inclusive of 34,670,420 and 16,577,495 shares, respectively, held by PGT, a consolidated VIE.

Dividends

Dividends on shares of the Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F and Series G convertible preferred stock are payable only when, as, and if declared by the Board of Directors. No dividends will be paid with respect to the common stock until any declared dividends on the Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, and Series G convertible preferred stock have been paid or set aside for payment to the Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, and Series G convertible preferred stockholders. After payment of any such dividends, any additional dividends or distributions will be distributed among all holders of common stock and preferred stock in proportion to the number of shares of common stock that would be held by each such holder if all shares of preferred stock were converted to common stock at the then-effective conversion rate. The Series A-1 convertible preferred shares have no dividend rights. To date, no dividends have been declared on any of PMI’s preferred stock or common stock.

Conversion

Under the terms of PMI’s amended and restated certificate of incorporation, the holders of preferred stock have the right to convert such preferred stock into common stock at any time. In addition, all preferred stock automatically converts into common stock (i) immediately prior to the closing of an initial public offering that values Prosper at least at $2 billion and that results in aggregate proceeds to Prosper of at least $100 million or (ii) upon a written request from the holders of at least 60% of the voting power of the outstanding preferred stock (on an as-converted basis), provided that (i) the Series A-1 convertible preferred stock shall not be converted without at least 14% of the voting power of the outstanding Series A-1 convertible preferred stock; (ii) the Series D shall not be converted without at least 60% of the voting power of the outstanding Series D; (iii) the Series E-1 and Series E-2 shall not be converted without at least 60% of the voting power of the outstanding Series E-1 and Series E-2, voting together as a single class; (iv) the Series F shall not be converted without at least 60% of the voting power of the outstanding Series F, and (v) the shares of Series G Preferred Stock will not be automatically converted unless the holders of at least 60% of the outstanding shares of Series G Preferred Stock approve such conversion. In addition, if a holder of the Series A convertible preferred stock has converted any of the Series A convertible preferred stock, then all of such holder’s shares of Series A-1 convertible preferred stock also will be converted upon a liquidation event (as defined under the certificate of incorporation). In lieu of any fractional shares of common stock to which a holder would otherwise be entitled, PMI shall pay such holder cash in an amount equal to the fair market value of such fractional shares, as determined by its Board of Directors. At present, each of the Series A, Series B, Series C, Series D, Series E-1, Series E-2, and Series F convertible preferred stock converts into PMI common stock at a 1:1 ratio. The Series A-1 convertible preferred stock converts into common stock at a 1,000,000:1 ratio and the Series G convertible preferred stock converts into common stock at a 1:1.36 ratio. The Series G convertible preferred stock conversion ratio reflects the Series G true-up that occurred at end of the vesting period for the Series E-2 and Series F Preferred Stock warrants.

For the Series G true-up, the conversion price of the Series G Convertible Preferred Stock was reduced to a number equal to the Series G Preferred Stock original issuance price, divided by the quotient obtained by dividing the Series G true-up amount by the total number of Series G Preferred Stock issued as of the Series G closing date. The Series G true-up amount means the aggregate number of shares of Series G Preferred Stock that would have been issued to the purchasers of the Series G Preferred Stock on the Series G closing date, if warrants to purchase shares of Series E-2 Preferred Stock or Series F Preferred Stock that were exercisable or exercised as of the true-up time (end of vesting period) had been exercisable or exercised as of such Series G closing date.

Liquidation Rights

PMI’s convertible preferred stock has been classified as temporary equity on the condensed consolidated balance sheets. The preferred stock is not redeemable; however, in the event of a voluntary or involuntary liquidation, dissolution, change in control or winding up of PMI, holders of the convertible preferred stock may have the right to receive its liquidation preference under the terms of PMI’s certificate of incorporation.

Each holder of Series E-1, Series E-2, and Series F convertible preferred stock is entitled to receive prior and in preference to any distribution of proceeds from a liquidation event (as defined under the certificate of incorporation) to the holders of Series A, Series B, Series C, Series D, Series G and Series A-1 convertible preferred stock or common stock, an amount per share for (i) each share of Series E-1 convertible preferred stock equal to the sum of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share, (ii) each share of Series E-2 convertible preferred stock equal to the sum of two-thirds the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share, and (iii) each share of Series F convertible preferred stock equal to the sum of two-thirds of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share.

After the payment or setting aside for payment to the holders of Series E-1, Series E-2, and Series F convertible preferred stock, each holder of Series A, Series B, Series C and Series D, Series E-2, Series F, and Series G convertible preferred stock is entitled to receive, on a pari passu basis, prior to and in preference to any distribution of proceeds from a liquidation event (as defined under the certificate of incorporation) to the holders of Series A-1 convertible preferred stock or common stock, (i) an amount per share for each share of Series E-2 and Series F convertible preferred stock equal to the sum of one-third of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share, and (ii) an amount per share for each share of Series A, Series B, Series C, Series D and Series G convertible preferred stock equal to the sum of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share.

After the payment or setting aside for payment to the holders of Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, and Series G convertible preferred stock, the holders of Series A-1 convertible preferred stock are entitled to receive, prior and in preference to any distribution of proceeds to the holders of common stock, an amount per share for each such share of Series A-1 convertible preferred stock equal to the sum of the liquidation preference specified for such share and all declared but unpaid dividends, if any, on such share.

After the payment or setting aside for payment to the holders of Series A, Series B, Series C, Series D, Series E-1, Series E-2, Series F, Series G, and Series A-1 convertible preferred stock, the entire remaining proceeds legally available for distribution will be distributed pro rata to the holders of Series A convertible preferred stock and common stock in proportion to the number of shares of common stock held by them assuming the Series A convertible preferred stock has been converted into shares of common stock at the then effective conversion rate, provided that the maximum aggregate amount per share of Series A convertible preferred stock which the holders of Series A convertible preferred stock shall be entitled to receive is three times the original issue price for the Series A convertible preferred stock.

At present, the liquidation preferences are equal to $0.29 per share for the Series A convertible preferred stock, $2.00 per share for the Series A-1 convertible preferred stock, $0.60 per share for the Series B convertible preferred stock, $2.87 per share for the Series C convertible preferred stock, $6.91 per share for the Series D convertible preferred stock, $0.84 per share for the Series E-1 convertible preferred stock, $0.84 per share for the Series E-2 convertible preferred stock, $0.84 per share for the Series F convertible preferred stock and $1.34 per share for the Series G convertible preferred stock.

Voting

Each holder of shares of convertible preferred stock is entitled to the number of votes equal to the number of shares of common stock into which such shares of convertible preferred stock could be converted and has voting rights and powers equal to the voting rights and powers of the common stock. The holders of convertible preferred stock and the holders of common stock vote together as a single class (except with respect to certain matters that require separate votes or as required by law), and are entitled to notice of any stockholders’ meeting in accordance with the Bylaws of PMI. 

Convertible Preferred Stock Warrant Liability

Series E-1 Warrants

In connection with the Settlement and Release Agreement dated November 17, 2016 among PMI, its wholly owned subsidiary Prosper Funding LLC (“PFL”) and Colchis, on December 16, 2016, PMI issued the First Series E-1 Warrant for 20,267,135 shares of Series E-1 convertible preferred stock. The Second Series E-1 Warrant for an additional 15,277,006 shares of Series E-1 convertible preferred stock was granted on the signing of the Consortium Purchase Agreement (as described in Note 13 of PMI’s 10-K for the year ended December 31, 2023) on February 27, 2017. The Series E-1 warrants have an exercise price of $0.01 per share and expire ten years from the date of issuance. For the three months ended March 31, 2024 and 2023, Prosper recognized $4.6 million and $0.7 million of income, respectively, from the re-measurement of the fair value of the warrants. The income or expense resulted from the remeasurement of the fair value of the warrants is recorded in Change in Fair Value of Convertible Preferred Stock Warrants on the condensed consolidated statements of operations.

To determine the fair value of the Series E-1 Warrants, the Company first determined the value of a share of Series E-1 Convertible Preferred Stock. To determine the fair value of the Convertible Preferred Stock, the Company first derived the business enterprise value (“BEV”) of the Company using a variety of valuation methods, including discounted cash flow models and market based methods, as deemed appropriate under the circumstances applicable at the valuation date. Once the Company determined an estimated BEV, the option pricing method (“OPM”) was used to allocate the BEV to the various classes of our equity, including our preferred stock. The concluded per share value for the Series E-1 Convertible Preferred Stock was utilized as an input to the Black-Scholes option pricing model.

The Company determined the fair value of the outstanding Series E-1 preferred stock warrants utilizing the following assumptions as of the following dates:

	March 31, 2024		December 31, 2023
Volatility	65.0	%	66.0	%
Risk-free interest rate	4.40	%	4.10	%
Expected term (in years)	2.75		2.75
Dividend yield	—	%	—	%

The above assumptions were determined as follows:

Volatility: The volatility is derived from historical volatilities of several unrelated publicly listed peer companies over a period approximately equal to the term of the warrant as the Company has limited information on the volatility of its preferred stock since there is currently no trading history. When making the selections of industry peer companies to be used in the volatility calculation, the Company considered the size, operational, and economic similarities to the Company’s principal business operations.

Risk-Free Interest Rate: The risk-free interest rate is based on the U.S. Treasury yield in effect as of March 31, 2024, and for zero coupon U.S. Treasury notes with maturities approximately equal to the term of the warrant.

Expected Term: The expected term is the period of time for which the warrants are expected to be outstanding.

Dividend Yield: The expected dividend assumption is based on the Company’s current expectations about the Company’s anticipated dividend policy.

Series F Warrants

In connection with the Consortium Purchase Agreement on February 27, 2017, PMI issued warrants to purchase up to 177,720,706 shares of PMI's Series F convertible preferred stock at $0.01 per share. The warrants expire ten years from the date of issuance. For the three months ended March 31, 2024 and 2023, Prosper recognized $23.1 million and $3.6 million of income, respectively, from the re-measurement of the fair value of the warrants. The income or expense resulting from changes in the fair value of the warrant is recorded through Change in Fair Value of Convertible Preferred Stock Warrants on the condensed consolidated statements of operations.

To determine the fair value of the Series F Warrants, the Company first determined the value of a share of Series F Convertible Preferred Stock. To determine the fair value of the Convertible Preferred Stock, the Company first derived the BEV using valuation methods, including a combination of methods, as deemed appropriate under the circumstances applicable at the valuation date. Once the Company determined an estimated BEV, the OPM was used to allocate the BEV to the various classes

of Prosper's equity, including our preferred stock. The concluded per share value for the Series F Convertible Preferred Stock warrants utilized the Black-Scholes option pricing model.

The Company determined the fair value of the outstanding Series F Warrants utilizing the following assumptions as of the following dates:

	March 31, 2024		December 31, 2023
Volatility	65.0	%	66.0	%
Risk-free interest rate	4.40	%	4.10	%
Expected term (in years)	2.75		2.75
Dividend yield	—	%	—	%

The above assumptions were determined using the same criteria described above for the Series E-1 Warrants.

The combined activity of the Convertible Preferred Stock Warrant Liability for the three months ended March 31, 2024 and 2023 are presented in Note 8, Fair Value of Assets and Liabilities. Starting with the Series E and F Warrant valuations prepared as of September 30, 2023, due to a change in methodology, the Company removed the discount for lack of marketability that was previously applied to the Black-Scholes option pricing valuation. If a discount for lack of marketability was applied to the valuation as of March 31, 2024, it would reduce the Convertible Preferred Stock Warrant Liability by approximately $36.4 million.

Common Stock

PMI, through its Amended and Restated Certificate of Incorporation, is the sole issuer of common stock and related options, RSUs and warrants. On February 16, 2016, PMI amended and restated its Certificate of Incorporation to, among other things, effect a 5-for-1 forward stock split. On September 20, 2017, PMI further amended its Amended and Restated Certificate of Incorporation to increase the number of shares of common stock authorized for issuance. The total number of shares of stock which PMI has the authority to issue is 1,069,760,848, consisting of 625,000,000 shares of common stock, $0.01 par value per share, and 444,760,848 shares of preferred stock, $0.01 par value per share. As described above, the Company repurchased 2,196,665 shares of Common Stock on December 23, 2019. As of March 31, 2024, 78,112,888 shares of common stock were issued and 77,176,953 shares of common stock were outstanding. As of December 31, 2023, 77,861,329 shares of common stock were issued and 76,925,394 shares of common stock were outstanding. Each holder of common stock is entitled to one vote for each share of common stock held.

Common Stock Issued upon Exercise of Stock Options

For the three months ended March 31, 2024, PMI issued 251,559 shares of common stock upon the exercise of vested options for cash proceeds of $8 thousand.

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

PMI grants equity awards primarily through its Amended and Restated 2005 Stock Option Plan (the “2005 Plan”), which was approved as amended and restated by its stockholders on December 1, 2010; and its 2015 Equity Incentive Plan, which was approved by its stockholders on April 7, 2015 and subsequently amended by an Amendment No. 1, Amendment No. 2 and Amendment No. 3, which were approved by PMI's stockholders effective as of February 15, 2016, May 31, 2016, and September 5, 2018 respectively (as amended, the “2015 Plan”). In March 2015, the 2005 Plan expired, except that any awards granted under the 2005 Plan prior to its expiration remain in effect pursuant to their terms.

Stock Option Activity

Stock option activity under the 2005 Plan and 2015 Plan is summarized for the three months ended March 31, 2024 below:

	Options Issued and Outstanding	Weighted Average Exercise Price
Balance as of January 1, 2024	82,113,271	$	0.15
Options issued	3,854,515	$	0.40
Options exercised	(251,559)	$	0.03
Options forfeited	(2,382,025)	$	0.18
Options expired	(15,000)	$	0.02
Balance as of March 31, 2024	83,319,202	$	0.16
Options vested and expected to vest as of March 31, 2024	76,528,968	$	0.16
Options vested and exercisable as of March 31, 2024	60,750,156	$	0.09

Other Information Regarding Stock Options

The weighted-average remaining contractual term for options outstanding as of March 31, 2024 is 5.65 years.

The fair value of options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires PMI to make assumptions and judgments about the variables used in the calculation, including the fair value of PMI’s common stock, the expected term (the period of time that the options granted are expected to be outstanding), the volatility of PMI’s common stock, a risk-free interest rate, and expected dividends. Given the absence of a publicly traded market, the Company considered numerous objective and subjective factors to determine the fair value of PMI’s common stock at each grant date. These factors included, but were not limited to: (i) contemporaneous valuations of common stock performed by unrelated third-party specialists, (ii) the prices for PMI’s preferred stock sold to outside investors, (iii) the rights, preferences and privileges of PMI’s preferred stock relative to PMI’s common stock, (iv) the lack of marketability of PMI’s common stock, (v) developments in the business, (vi) secondary transactions of PMI’s common and preferred shares, and (vii) the likelihood of achieving a liquidity event, such as an initial public offering or a merger or acquisition of Prosper, given prevailing market conditions. As PMI’s stock is not publicly traded, volatility for stock options is based on an average of the historical volatilities of the common stock of several entities with characteristics similar to those of PMI. The expected term assumptions were determined based on the vesting terms, exercise terms and contractual lives of the options using the simplified method. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. PMI uses an expected dividend yield of zero as it does not anticipate paying any dividends in the foreseeable future.

PMI also estimates forfeitures of unvested stock options. Expected forfeitures are based on the Company’s historical experience. To the extent actual forfeitures differ from the estimates, the difference will be recorded as a cumulative adjustment in the period estimates are revised. No compensation cost is recorded for options that do not vest.

The fair value of PMI’s stock option awards granted during the three months ended March 31, 2024 and 2023 was estimated at the date of grant using the Black-Scholes model with the following average assumptions:

	Three Months Ended March 31,
	2024		2023
Volatility of common stock	66.30	%	66.69	%
Risk-free interest rate	4.17	%	3.67	%
Expected life (in years)	6.0 years		6.0 years
Dividend yield	—	%	—	%

Restricted Stock Unit Activity

In previous years, PMI granted RSUs to certain employees that are subject to three-year or four-year vesting terms and the occurrence of a liquidity event.

The following table summarizes the number of PMI’s RSU activity for three months ended March 31, 2024:

	Number of Shares	Weighted-Average Grant Date Fair Value
Unvested at January 1, 2024	2,574,633	$	1.03
Forfeited	(9,500)	$	2.18
Unvested at March 31, 2024	2,565,133	$	1.02

Share Based Compensation

The following table presents the amount of stock-based compensation related to stock-based awards granted to employees recognized in Prosper’s condensed consolidated statements of operations for the periods presented (in thousands):

	Three Months Ended March 31,
	2024		2023
Origination and servicing	$	19	$	21
Sales and marketing	113		36
General and administrative	260		311
Total stock-based compensation	$	392	$	368

As of March 31, 2024, the unamortized stock-based compensation expense, adjusted for forfeiture estimates, related to unvested stock-based awards was approximately $3.0 million, which will be recognized over a remaining weighted-average vesting period of approximately 2.6 years.

Income Taxes

For the three months ended March 31, 2024 and 2023, PMI recognized $26 thousand and $70 thousand of income tax expense, respectively. The income tax expense relates to state income tax expense and the amortization of tax deductible goodwill which gives rise to an indefinite-lived deferred tax liability. No other income tax expense or benefit was recorded for the three month periods ended March 31, 2024 and 2023 due to a full valuation allowance recorded against the Company’s deferred tax assets.

Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize our existing deferred tax assets. On the basis of this evaluation, it is not more likely than not that our deferred tax assets will be realized and therefore a full valuation allowance has been recorded.

Since PMI is in a taxable loss position, is not currently subject to income taxes, and has fully reserved against its deferred tax asset, the net effective tax rate for PFL is 0%.

Leases [Abstract]

LEASES

Leases

Prosper has operating leases for corporate offices and a data center. These leases have remaining lease terms of less than one year to approximately five years. Some of the lease agreements include options to extend the lease term for up to an additional five years. Rental expense under operating lease arrangements was $1.0 million and $1.1 million for the three months ended March 31, 2024 and 2023. Additionally, Prosper subleases certain leased office space to third parties when it determines there is excess leased capacity. Sublease income from operating lease arrangements was $0.1 million and $0.2 million for the three months ended March 31, 2024 and 2023.

Operating Lease Right-of-Use (“ROU”) Assets

The following table summarizes the operating lease right-of-use assets as of March 31, 2024, which are included in “Property and Equipment, Net” on the condensed consolidated balance sheets.

	March 31, 2024
	Gross Carrying Value		Accumulated Amortization		Net Carrying Value
ROU Assets - Office buildings	$	22,690	$	12,347	$	10,343

No impairment charge was identified for the three months ended March 31, 2024 and 2023.

In March 2024, the Company entered into an amendment to its Phoenix office lease, the most prominent impact of which was to extend the lease term for an additional period through October 2029. As a result of this lease modification, the Company recorded additional ROU operating lease assets and liabilities of $0.3 million.

Commitments and Contingencies

Commitments and Contingencies

In the normal course of its operations, Prosper becomes involved in various legal actions. Prosper maintains provisions it considers to be adequate for such actions. Prosper does not believe it is probable that the ultimate liability, if any, arising out of any such matters will have a material effect on Prosper's financial condition, results of operations or cash flows.

Operating Commitments

PMI, along with PFL, and WebBank have entered into: (i) an Asset Sale Agreement, dated July 1, 2016, between PFL and WebBank, as most recently amended by a Seventh Amendment dated February 28, 2024 (as amended, the “Sale Agreement”); (ii) the Marketing Agreement, dated July 1, 2016, between PMI and WebBank, as most recently amended by a Seventh Amendment dated February 28, 2024 (as amended, the “Marketing Agreement”); and (iii) the Stand By Purchase Agreement, dated July 1, 2016, between PMI and WebBank, as most recently amended by a Fourth Amendment dated February 28, 2024 (as amended, the “Purchase Agreement” and, collectively with the Sale Agreement and the Marketing Agreement, the “Origination and Sale Agreements”). Under the Origination and Sale Agreements, all Borrower Loans originated through the marketplace are made by WebBank under its bank charter.

The Origination and Sale Agreements contain terms through February 1, 2027. Prosper is required, under the Origination and Sale Agreements, to maintain certain collateral requirements. In addition, pursuant to the Marketing Agreement, the marketing fee that Prosper receives in connection with the origination of each loan is partially reduced by an amount (the “Designated Amount”) calculated as a percentage of the principal amount of such loan based on the aggregate principal amount of loans originated for the applicable month. To the extent the aggregate Designated Amount for all loans originated during any month is less than $100,000 through February 1, 2027, Prosper is required to pay WebBank an amount

equal to such deficiency. Accordingly, the minimum fee is $0.9 million for the remaining nine months of 2024, $1.2 million in 2025, $1.2 million in 2026 and $0.1 million in 2027.

Additionally, under the Origination and Sale Agreements, Prosper is required to maintain a minimum net liquidity of $15.0 million at all times during the term of the agreement. Net liquidity is defined as the sum of Cash, Cash Equivalents and Available for Sale Investments. Violation of this covenant can result in termination of the contract with WebBank. As of March 31, 2024, the Company was in compliance with the covenant.

Transaction Fee Refunds

Prosper assumes WebBank’s liability under Utah law to refund the pro-rated amount of any transaction fees collected in excess of 5%, in the event the underlying borrower prepays the loan before full maturity. The Company has accrued $3.9 million and $1.6 million as of March 31, 2024 and December 31, 2023, respectively, related to anticipated future refunds under this obligation.

Loan Purchase Commitments

Prosper entered into an agreement with WebBank to purchase $15.0 million of Borrower Loans that WebBank originated during the last two business days of the quarter ended March 31, 2024. Prosper will purchase these Borrower Loans within the first two business days of the quarter ending June 30, 2024.

Repurchase Obligation    

Under the terms of the loan purchase agreements between Prosper and investors that participate in the Whole Loan Channel, Prosper may, in certain circumstances, become obligated to repurchase a Borrower Loan from an investor. Generally, these circumstances include the occurrence of verifiable identity theft, the failure to properly follow personal loan listing or bidding protocols or a violation of the applicable federal, state or local lending laws. Prosper recognizes a liability at fair value for the repurchase obligation when the Borrower Loans are sold. The fair value of the repurchase obligation is estimated based on historical experience. Repurchased Borrower Loans associated with violations of federal, state or local lending laws or verifiable identity theft are written off at the time of repurchase. The maximum potential amount of future payments associated with this obligation is the outstanding balances of the Borrower Loans issued to third parties through the Whole Loan Channel, which at March 31, 2024 is $3.1 billion. Prosper has accrued $0.4 million and $0.5 million as of March 31, 2024 and December 31, 2023, respectively, in regard to this obligation.

Under the terms of the indenture and investor registration agreement, Prosper may, in certain circumstances, become obligated to either repurchase a Note or indemnify the investor for any losses resulting from nonpayment of a Note purchased in the Retail Channel. The decision to repurchase or indemnify is in Prosper’s sole discretion. These circumstances include, but are not limited to, the occurrence of verifiable identity theft, a technical error in the automated bidding tools which results in the purchase of a Note that does not match the investor’s investment criteria, or situations in which a personal loan listing includes a Prosper Rating that is different from the Prosper Rating that should have appeared in the listing for the corresponding Borrower Loan because either PFL inaccurately input data into, or inaccurately applied, the formula for determining the Prosper Rating and, as a result, the interest of the investor is materially and adversely affected. During the three months ended March 31, 2024 the Company repurchased $0.1 million of Notes under these circumstances, and has agreed to indemnify additional Notes with an unpaid principal balance of $0.7 million as of March 31, 2024.

Regulatory Contingencies

Prosper accrues for contingencies when a loss from such contingencies is probable and the amount of loss can be reasonably estimated. In determining whether a loss is probable and if it is possible to quantify the amount of the estimated loss, Prosper reviews and evaluates its litigation and regulatory matters on at least a quarterly basis in light of potentially relevant factual and legal developments. If Prosper determines that an unfavorable outcome is not probable or that the amount of a loss cannot be reasonably estimated, Prosper does not accrue for a potential litigation loss. If an unfavorable outcome is probable and Prosper can estimate a range of outcomes, an amount is recorded which management considers to be the best estimate within the range of potential losses that are both probable and estimable; however, if management cannot quantify the amount of the estimated loss, then the low end of the range of the potential losses is recorded.

West Virginia Matter

In February 2020, Prosper received a proposed Assurance of Discontinuance (an “AOD”) from the Attorney General of the State of West Virginia (the “WV Attorney General”) requesting that, without in any way admitting that any of its prior practices were in violation of the West Virginia Consumer Credit and Protection Act (the “Consumer Act”), Prosper agree to certain terms and conditions regarding its past and potential future conduct of its business with respect to customers in West Virginia, including a release by the WV Attorney General of any claims it may have related to the matters identified in the AOD.

We cannot predict the outcome of the matter and any potential fines or penalties, if any, that may arise from the matter. Further, we are unable to estimate a range of outcomes and as a result no accrual has been made.

No loans have been originated through the Prosper platform to West Virginians since June 2016 and the final loan originated through the Prosper platform to a borrower in West Virginia was repaid in October 2021.

Significant Concentrations

Significant Concentrations

Prosper is dependent on third-party funding sources such as banks, asset managers, investment funds and Warehouse Lines to provide the funds to allow WebBank to originate Borrower Loans that the third-party funding sources will later purchase. Of all Borrower Loans originated in the three months ended March 31, 2024, five individual third parties purchased 31.3%, 19.3%, 12.1%, 10.3% and 10.3% of all Borrower Loans originated. There were no purchases of such loans by the Company’s VIEs during the three months ended March 31, 2024. For the three months ended March 31, 2023, individual third parties purchased 11.1% and 10.2% of all Borrower Loans originated, and the Company’s Warehouse VIEs purchased 20.0% of such loans.

Prosper receives all of its personal loan transaction fee revenue from WebBank. Prosper earns a transaction fee from WebBank for its services in facilitating originations of Borrower Loans issued by WebBank. The rate of the transaction fee for each individual Borrower Loan is based on the term and credit grade of the Borrower Loan. Starting in the fourth quarter of

2023, the Company raised its transaction fee cap from 5.0% to 7.99% for certain newly originated loans. No individual borrower or investor accounted for 10% or more of consolidated net revenue for any of the periods presented.

Segments

Segments

Starting with the fourth quarter of 2022, the Company realigned its reportable and operating segments to better reflect the nature and materiality of its product offerings. As a result of these changes, the Company now has three reportable and operating segments: Personal Loan, Home Equity and Credit Card.

The Company’s Chief Executive Officer, who serves as the chief operating decision maker (“CODM”) evaluates the financial performance of the Company’s segments based upon segment revenues, as well as segment Adjusted Net Revenue and segment Adjusted EBITDA, both non-GAAP profitability measures. Items outside of Adjusted EBITDA are not reported by segment, since they are excluded from the measure of segment profitability reviewed by the CODM. The Company’s CODM does not use segment assets to allocate resources or to assess performance of the segments and, therefore, total segment assets have not been disclosed.

The tables below present segment information reconciled to consolidated Total Net Revenue and Net Income (Loss) Before Income Taxes, as well as interest income and expense included in segment Adjusted Net Revenue and Adjusted EBITDA, for the periods indicated (in thousands).

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2024

Entity Information [Line Items]

Basis of Presentation

Prosper Marketplace, Inc. (“PMI” or the “Company”) was incorporated in the state of Delaware on March 22, 2005. Except as the context requires otherwise, as used in these notes to the condensed consolidated financial statements of PMI, “Prosper,” “we,” “us,” and “our” refer to PMI and its wholly-owned subsidiaries, on a consolidated basis.

The unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) and disclosure requirements for interim financial information and the requirements of Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2023. The balance sheet at December 31, 2023 has been derived from the audited financial statements at that date. Management believes these unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

PMI did not have any items of other comprehensive income or loss for any of the periods presented in the condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023.

The preparation of Prosper’s condensed consolidated financial statements and related disclosures in conformity with US GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in Prosper’s financial statements and accompanying notes. Management bases its estimates on historical experience and on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities. These judgments, estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions.

The accompanying interim condensed consolidated financial statements include the accounts of PMI, its wholly-owned subsidiaries and consolidated VIEs. All intercompany balances have been eliminated in consolidation.

Notes Issued by Securitization Trust are notes held by certain third-party investors pursuant to Prosper’s securitization transactions, and are distinguishable from the borrower payment dependent Notes available to investors through the Company’s Note Channel.

Fair Value Measurements

Fair Value Measurements

Financial instruments measured at fair value consist principally of Borrower Loans (Note 4), Loans Held for Sale (Note 4), Servicing Assets (Note 6), Credit Card Derivative (Note 5), Loan Trailing Fee Liabilities (Note 10), Debt (Note 11) and Convertible Preferred Stock Warrant Liability (Note 13). The estimated fair values of other financial instruments, including Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable and Accrued Liabilities, and Payable to Investors approximate their carrying values because of their short-term nature. The estimated fair values of the Term Loan and Warehouse Lines (Note 11) do not approximate their carrying values due primarily to differences in the stated and market rates associated with these instruments.

Restricted Cash

Restricted Cash

Restricted cash consists primarily of cash deposits, money market funds and short-term certificate of deposit accounts held as collateral as required for loan funding and servicing activities, and cash that investors or Prosper have on the marketplace that has not yet been invested in Borrower Loans or disbursed to the investor.

Borrower Loans, Loans Held for Sale and Notes

Borrower Loans, Loans Held for Sale and Notes

Borrower Loans are funded either through the Note Channel or through the Whole Loan Channel. Through the Note Channel, Prosper purchases Borrower Loans from WebBank, then issues Notes and holds the Borrower Loans until maturity. The obligation to repay a series of Notes issued through the Note Channel is dependent upon the repayment of the associated Borrower Loan. Borrower Loans funded and Notes issued through the Note Channel are carried on Prosper’s condensed consolidated balance sheets as assets and liabilities, respectively.

Until March 2024, Prosper used Warehouse Lines to purchase Loans Held for Sale that could be subsequently contributed to securitization transactions or sold to investors. Loans Held for Sale were included in “Loans Held for Sale, at Fair Value” on the condensed consolidated balance sheets. In September 2023 and March 2024, in connection with the securitization transactions discussed below, the Loans Held for Sale in these Warehouse Lines were fully contributed to the securitization entities or purchased by Prosper, and the outstanding balances of the Warehouse Lines were fully paid down. See Note 11, Debt for more details on the termination of the Warehouse Lines.

In September 2023 and March 2024, Prosper closed two separate securitization transactions, PMIT 2023-1 and PMIT 2024-1, respectively, with personal loans previously funded through its PWIIT Warehouse Line and PWIT Warehouse Line, respectively. These newly formed securitization entities issued notes acquired by third parties and residual certificates acquired by PMI (a majority owned affiliate of PFL, the sole sponsor of the securitizations). PMIT 2023-1 and PMIT 2024-1 are deemed consolidated VIEs, and as a result the Borrower Loans they hold are presented in “Borrower Loans, at Fair Value,” and the notes sold to third-party investors are included in “Notes Issued by Securitization Trust” on the accompanying condensed consolidated balance sheets.

Borrower Loans and Loans Held for Sale are purchased from WebBank. Prosper places Borrower Loans and Loans Held for Sale on non-accrual status when they are 120 days past due. When a loan is placed on non-accrual status, Prosper stops accruing interest and reverses all accrued but unpaid interest as of such date. Additionally, Prosper charges-off Borrower Loans and Loans Held for Sale when they are 120 days past due. The fair value of loans 120 or more days past due generally consists of the expected recovery from debt sales in subsequent periods.

Prosper has elected the fair value option for Borrower Loans, Loans Held for Sale and Notes. Changes in the fair value of Borrower Loans funded through the Note Channel are largely offset by the changes in fair value of Notes due to the borrower payment-dependent design of the Notes. Changes in the fair value of Borrower Loans and Loans Held for Sale are recorded through Proper's earnings and Prosper collects interest on Borrower Loans and Loans Held for Sale. Changes in the fair values of Borrower Loans, Loans Held for Sale and Notes are included in “Change in Fair Value of Financial Instruments” on the accompanying condensed consolidated statements of operations.

Prosper primarily uses a discounted cash flow model to estimate the fair value of Borrower Loans, Loans Held for Sale and Notes. The key assumptions used in the valuation include default rates and prepayment rates derived primarily from historical performance, and discount rates based on estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.

Credit Card Derivative

Credit Card Derivative

The Company evaluated the terms of its Credit Card program agreement (the “Credit Card Program Agreement”) with Coastal Community Bank (“Coastal”) and determined that it contained features that met the definition of derivatives under Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging. These features are freestanding financial instruments (as defined under ASC 480, Distinguishing Liabilities from Equity), and have been valued separately as derivatives. A right of offset exists between the derivatives, and they are presented net on the accompanying consolidated balance sheets. Changes in the fair value of the Credit Card Derivative, as well as settled transactions from the Credit Card portfolio, are recorded in “Change in Fair Value of Financial Instruments” on the accompanying condensed consolidated statements of operations.

Term Loan

Term Loan

Prosper entered into a Credit Agreement, which provided for a Term Loan with a third-party financial institution in November 2022, which is more fully described in Note 11, Debt. This Term Loan is carried at amortized cost, net of discounts and issuance costs, which are subsequently amortized to Interest Expense on Term Loan over the life of the underlying agreement.

Interest Expense on Term Loan is presented as a component of Expenses on the accompanying condensed consolidated statements of operations, except for any portion associated with Term Loan proceeds used to purchase Loans Held for Sale through the Company’s Warehouse Lines, which is presented in “Interest Expense on Financial Instruments” as a component of Net Interest Income on the accompanying condensed consolidated statement of operations.

Leases

Leases

Management determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and operating lease liabilities are included on the Condensed Consolidated Balance Sheets in Property and Equipment, Net and in Other Liabilities, respectively. For certain leases with original terms of twelve months or less, PMI recognizes the lease expense as incurred and does not record ROU assets and lease liabilities.

If a contract contains a lease, management evaluates whether it should be classified as an operating or finance lease. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. As most of PMI's leases do not provide an implicit rate, management uses an incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The operating lease ROU assets are evaluated for impairment utilizing the same impairment model used for Property and Equipment.

Consolidation of Variable Interest Entities

Consolidation of Variable Interest Entities

The determination of whether to consolidate a VIE in which we have a variable interest requires a significant amount of analysis and judgment regarding whether we are the primary beneficiary of a VIE due to our holding a controlling financial interest in the VIE. A controlling financial interest in a VIE exists if we have both the power to direct the VIE’s activities that most significantly affect the VIE’s economic performance and a potentially significant economic interest in the VIE. The determination of whether an entity is a VIE considers factors, such as (i) whether the entity’s equity investment at risk is insufficient to allow the entity to finance its activities without additional subordinated financial support and (ii) whether a holder’s equity investment at risk lacks any of the following characteristics of a controlling financial interest: the direct or indirect ability through voting rights or similar rights to make decisions about a legal entity’s activities that have a significant effect on the entity’s success, the obligation to absorb the expected losses of the entity or the right to receive the expected residual returns of the legal entity.

Management regularly reviews and reconsiders its previous conclusions regarding the status of an entity as a VIE and whether we are required to consolidate or deconsolidate such VIE in the consolidated financial statements.

Accounting Standards Issued, to be Adopted by the Company in Future Periods

In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, “Reference Rate Reform (Topic 848),” which provides optional expedients and exceptions for applying GAAP on contract modifications and hedge accounting, in order to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative referenced rates, such as the Secured Overnight Financing Rate. The optional guidance, which became effective on March 12, 2020, could be applied through December 31, 2022. In December 2022, the FASB issued No 2022-06 extending the sunset date of the relief provided under ASU No. 2020-04 to December 31, 2024. The Company amended its agreements and transitioned to SOFR for contracts that previously referenced LIBOR. The Company continues to evaluate potential future impacts that may result from the discontinuation of LIBOR or other reference rates as well as the accounting provided in this update on our financial condition, results of operations, and cash flows.

In October 2023, the FASB issued ASU No. 2023-06, “Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission’s Disclosure Update and Simplification Initiative”. The amendments in this update modify the disclosure or presentation requirements of a variety of Topics in the ASC in response to the SEC’s Release No. 33-10532, “Disclosure Update and Simplification Initiative”, and align the ASC’s requirements with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective. Early adoption is prohibited. The Company does not expect the adoption of this ASU to have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which updates reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which enhances effective tax rate reconciliation disclosure requirements and provides clarity to the disclosures of income taxes paid, income before taxes and provision for income taxes. The amendments are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this update should be applied on a prospective basis. Retrospective application is permitted. The Company is currently evaluating this ASU to determine its impact on the Company’s disclosures.

Other recent accounting pronouncements issued by the FASB did not, or are not believed by management to, have a material impact on the Company’s present or future financial statements.

Prosper Funding LLC

Entity Information [Line Items]

Basis of Presentation

Prosper Funding LLC (“PFL”) was formed in the state of Delaware in February 2012 as a limited liability company with Prosper Marketplace, Inc. (“PMI”) as its sole equity member. Except as the context otherwise requires, as used in these Notes to the condensed consolidated financial statements of Prosper Funding LLC, “PFL,” and the “Company” refers to Prosper Funding LLC and its wholly owned subsidiary, Prosper Depositor LLC, a Delaware limited liability company, on a consolidated basis.

The unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”) and disclosure requirements for interim financial information and the requirements of Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. The unaudited interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto for the year ended December 31, 2023. The balance sheet at December 31, 2023 has been derived from the audited financial statements at that date. Management believes these unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

PFL did not have any items of other comprehensive income or loss for any of the periods presented in the condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023.

The preparation of PFL's condensed consolidated financial statements and related disclosures in conformity with US GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in its condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and on various other factors it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of certain assets and liabilities. These judgments, estimates and assumptions are inherently subjective in nature and actual results may differ from these estimates and assumptions, and the differences could be material.

Fair Value Measurements

Fair Value Measurements

Financial instruments consist principally of Cash and Cash Equivalents, Restricted Cash, Borrower Loans, Loans Held for Sale, Accounts Receivable, Accounts Payable and Accrued Liabilities, Payable to Investors and Notes. The estimated fair values of Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable and Accrued Liabilities, and Payable to Investors approximate their carrying values because of their short-term nature.

Restricted Cash

Restricted Cash

Restricted Cash consists primarily of cash deposits, money market funds and short-term certificate of deposit accounts held as collateral as required for long term leases, loan funding and servicing activities, and cash that investors have on our marketplace that has not yet been invested in Borrower Loans or disbursed to the investor.

Borrower Loans, Loans Held for Sale and Notes

Borrower Loans, Loans Held for Sale and Notes

With respect to the Note Channel, PFL purchases Borrower Loans from WebBank, then issues Notes and holds the Borrower Loans until maturity. The obligation to repay a series of Notes funded through the Note Channel is dependent upon the repayment of the associated Borrower Loan. Borrower Loans and Notes funded through the Note Channel are carried on PFL’s condensed consolidated balance sheets as assets and liabilities, respectively.

PFL places Borrower Loans and Loans Held for Sale on non-accrual status when they are 120 days past due. When a loan is placed on non-accrual status, PFL stops accruing interest and reverses all accrued but unpaid interest as of such date. Additionally, PFL charges-off Borrower Loans and Loans Held for Sale when they are 120 days past due. The fair value of loans 120 days past due generally consists of the expected recovery from debt sales in subsequent periods.

Management has elected the fair value option for Borrower Loans, Loans Held for Sale, and Notes. Changes in fair value of Borrower Loans are largely offset by the changes in fair value of Notes due to the borrower payment-dependent design of the Notes. Changes in fair value of Borrower Loans, Loans Held for Sale and Notes are included in “Change in Fair Value of Financial Instruments, Net” on the condensed consolidated statements of operations.

PFL primarily uses a discounted cash flow model to estimate the fair value of Borrower Loans, Loans Held for Sale and Notes. The key assumptions used in the valuation include default rates and prepayment rates derived primarily from historical performance and discount rates based on estimates of the rates of return that investors would require when investing in financial instruments with similar characteristics.
