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, 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, a discount rate based on the estimated residual return derived from a recent market securitization transaction sponsored by the Company is applied to the individual freestanding derivatives.
In order to determine the fair value of the Receivable from Credit Card Partner, Prosper uses a discounted cash flow model to estimate the fair value of the securitization residual interest, given that the Company is the sole sponsor of the securitization and is entitled to all residual cash flows it generates. This involves utilizing certain assumptions similar to those used to value the Credit Card Derivative, including the discount and prepayment rates. Additional assumptions are adjusted to reflect the specific characteristics of the securitized Credit Card receivables, including the average portfolio interest rate and the default rate. The residual interest fair value is then added to the applicable securitization advance rate applied to the outstanding balance of the Credit Card receivables to calculate the estimated fair value of Receivable from Credit Card Partner.
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, Receivable from Credit Card Partner, Credit Card Derivative, Servicing Assets, Notes, Credit Card servicing obligation liability, loan trailing fee liability and Convertible Preferred Stock Warrant 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 nine months ended September 30, 2026 and 2025.

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, as more fully described in Note 7, Securitizations. The Company has not designated any new personal loans as Loans Held for Sale since these transactions, other than loans that are purchased and immediately sold through the Whole Loan Channel. This movement of loans through the Whole Loan Channel is reflected in the accompanying consolidated statements of cash flows and the Level 3 tables above. Details on the fair value of the Servicing Asset associated with loans sold through the Whole Loan Channel are discussed 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.
Changes in Estimates
The Company periodically reviews the underlying assumptions and data sources that drive the fair values of its financial instruments. Accordingly, effective March 31, 2026, and on a prospective basis, the Company applied a default rate to the projected cash flows that comprise the Credit Card Derivative and Credit Card servicing obligation based solely on the recent credit performance of its underlying Credit Card portfolio. Previously, the default rate was estimated based on a combination of the Company’s recent credit performance, and the credit performance of comparable third-party credit card products. This change was made to better align with how management believes a market participant would estimate the fair value of these cash flows, given there is now more than four years of historical data available for the underlying Credit Card portfolio. The effect of this change in estimate increased the Credit Card Derivative by $5.2 million and increased the Credit Card servicing obligation by $0.7 million as of March 31, 2026.
In addition, effective September 30, 2026, and on a prospective basis, the Company applied a discount rate to the projected cash flows that comprise the Credit Card Derivative, Receivable from Credit Card Partner and Credit Card servicing obligation based on an estimated residual return derived from recent market securitization transactions sponsored by the Company. Previously, the discount rate was estimated using an external high-yield corporate debt benchmark. This change was made because management concluded the external benchmark is no longer representative of the returns a market participant would seek when investing in consumer credit, and the residual yield required by investors on recent market transactions provides a more representative measure. The effect of this change in estimate (i) increased the Credit Card Derivative by $2.7 million, (ii) increased the Receivable from Credit Card Partner by $6.0 million and (iii) increased the net Credit Card servicing obligation by $0.4 million as of September 30, 2026. Accordingly, it increased Total Net Revenue and Net Income by $8.4 million for the three and nine months ended September 30, 2026.

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 September 30, 2026 and December 31, 2025, 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.

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 nine months ended September 30, 2026 or September 30, 2025.

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.
