Business and Organization	Business and Organization KKR Real Estate Finance Trust Inc. (together with its consolidated subsidiaries, referred to throughout this report as the "Company" or "KREF") is a Maryland corporation that was formed and commenced operations on October 2, 2014 as a mortgage real estate investment trust ("REIT") that focuses primarily on originating and acquiring transitional senior loans secured by commercial real estate ("CRE") assets. KREF has elected and intends to maintain its qualification to be taxed as a REIT under the requirements of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), for U.S. federal income tax purposes. As such, KREF will generally not be subject to U.S. federal income tax on that portion of its income that it distributes to stockholders if it distributes at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gains. See Note 16 regarding taxes applicable to KREF. KREF is externally managed by KKR Real Estate Finance Manager LLC ("Manager"), an indirect subsidiary of KKR & Co. Inc. (together with its subsidiaries, "KKR"), through a management agreement ("Management Agreement") pursuant to which the Manager provides a management team and other professionals who are responsible for implementing KREF’s business strategy, subject to the supervision of KREF’s board of directors. For its services, the Manager is entitled to management fees and incentive compensation, both defined in, and in accordance with the terms of, the Management Agreement (Note 14). As of June 30, 2024, KKR beneficially owned 10,000,001 shares, or 14.4% of KREF's outstanding common stock. KREF's principal business activities are related to the origination and purchase of credit investments related to CRE. Management assesses the performance of KREF's current portfolio of leveraged and unleveraged commercial real estate loans and makes operating decisions accordingly. As a result, management presents KREF's operations within a single reporting segment.

Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation — The accompanying unaudited condensed consolidated financial statements and related notes of KREF are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and instructions to Form 10-Q. The condensed consolidated financial statements, including the accompanying notes, are unaudited and exclude some of the disclosures required in annual financial statements. The condensed consolidated financial statements include the accounts of KREF and its consolidated subsidiaries, and all intercompany transactions and balances have been eliminated. In the opinion of management, all adjustments considered necessary for a fair presentation of KREF’s financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These condensed consolidated financial statements should be read in conjunction with KREF's Annual Report on Form 10-K. Use of Estimates — The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Management makes subjective estimates to project cash flows KREF expects to receive on its investments in loans and securities as well as the related market discount rates, which significantly impact the interest income, impairments, allowance for loan loss and fair values recorded or disclosed. Actual results could materially differ from those estimates. Consolidation — KREF consolidates those entities that (i) it controls through either majority ownership or voting rights or (ii) management determines that KREF is the primary beneficiary of entities deemed to be variable interest entities ("VIEs"). Variable Interest Entities — VIEs are entities (i) in which equity investors do not have an interest with the characteristics of a controlling financial interest, (ii) that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or (iii) established with non-substantive voting rights. A VIE is required to be consolidated only by its primary beneficiary, which is defined as the party that has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and that has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could be potentially significant to the VIE (Note 9). To assess whether KREF has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, KREF considers all the facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes, first, identifying the activities that most significantly impact the VIE’s economic performance; and second, identifying which party, if any, has power to direct those activities. To assess whether KREF has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE, KREF considers all of its economic interests and applies judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Collateralized Loan Obligations — KREF consolidates collateralized loan obligations (“CLOs”) when it determines that the CLO issuers are VIEs and that KREF is the primary beneficiary of such VIEs. The collateral assets of KREF's CLOs, comprised of a pool of loan participations, are included in “Commercial real estate loans, held-for-investment, net” on the Condensed Consolidated Balance Sheets. The liabilities of KREF's consolidated CLOs consist solely of obligations to the senior CLO noteholders, excluding subordinated CLO tranches held by KREF as such interests are eliminated in consolidation, and are presented in “Collateralized loan obligations, net” on the Condensed Consolidated Balance Sheets. The collateral assets of the CLOs can only be used to settle the obligations of the consolidated CLOs. The interest income from the CLOs’ collateral assets and the interest expense on the CLOs’ liabilities are presented on a gross basis in “Interest income” and “Interest expense”, respectively, in KREF's Condensed Consolidated Statements of Income. Real Estate Owned Joint Venture — KREF has two joint ventures that hold the majority of KREF’s investments in real estate owned (“REO”) and determined the joint ventures to be VIEs (Note 9). KREF owns a majority of the equity interests in the joint ventures and participates in the profits and losses. Management concluded that KREF is the primary beneficiary of the joint ventures as KREF holds decision-making power over the activities that most significantly impact the economic performance and has the obligation to absorb losses or the right to receive benefits that could be potentially significant to the joint ventures. Noncontrolling Interests — Noncontrolling interests represent the ownership interests in certain consolidated subsidiaries held by entities or persons other than KREF. These noncontrolling interests do not include redemption features and are presented as "Noncontrolling interests in equity of consolidated joint ventures" on the Condensed Consolidated Balance Sheets. Equity Method Investments — Investments are accounted for under the equity method when KREF has significant influence over the operations of an investee but does not consolidate that investment. Equity method investments, for which management has not elected a fair value option, are initially recorded at cost and subsequently adjusted for KREF's share of net income or loss and cash contributions and distributions each period. KREF classifies distributions received from equity method investees using the cumulative earnings approach. Distributions received up to the cumulative earnings from each equity method investee are considered returns on investment and presented within “Cash Flows from Operating Activities” in the Condensed Consolidated Statements of Cash Flows; excess distributions received are considered returns of investment and presented within “Cash Flows From Investing Activities” in the Condensed Consolidated Statements of Cash Flows. Fair Value — GAAP requires the categorization of the fair value of financial instruments into three broad levels that form a hierarchy based on the transparency of inputs to the valuation. Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs are other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 — Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. KREF follows this hierarchy for its financial instruments. The classifications are based on the lowest level of input that is significant to the fair value measurement. Valuation Process — The Manager reviews the valuation of Level 3 financial instruments as part of KKR's quarterly process. As of June 30, 2024, KKR’s valuation process for Level 3 measurements, as described below, subjected valuations to the review and oversight of various committees. KKR has a global valuation committee assisted by the asset class-specific valuation committees, including a real estate valuation committee that reviews and approves all preliminary Level 3 valuations for real estate assets, including the financial instruments held by KREF. The global valuation committee is responsible for coordinating and implementing KKR’s valuation process to ensure consistency in the application of valuation principles across portfolio investments and between periods. All Level 3 valuations are also subject to approval by the global valuation committee. Valuation of Commercial Real Estate Loans — Management considers KREF's commercial real estate loans to be Level 3 assets in the fair value hierarchy as such assets are illiquid, structured investments that are specific to the sponsor, underlying property and its operating performance (Note 15). For financial statement disclosure purposes, on a quarterly basis, management generally engages an independent valuation firm to estimate the fair value of each loan categorized as a Level 3 asset. These loans are generally valued using a discounted cash flow model based on assumptions regarding the collection of principal and interest and estimated market rates. Management reviews the quarterly loan valuation estimates provided by the independent valuation firm. For collateral dependent loans, KREF may apply alternative valuation methods based on the fair value of the underlying collateral. Determination of collateral value involves significant judgment, including assumptions regarding capitalization rates, discount rates, leasing, occupancy rates, and other factors. Valuation of CLO Consolidated VIEs — Management estimates the fair value of the CLO liabilities using prices obtained from an independent valuation firm. If prices received from the independent valuation firm are inconsistent with values determined in connection with management’s independent review, management makes inquiries to the independent valuation firm about the prices received and related methods. In the event management determines the price obtained from an independent valuation firm to be unreliable or an inaccurate representation of the fair value of the CLO liabilities (based on considerations given to observable market data), management then compiles evidence independently and presents the independent valuation firm with such evidence supporting a different value. As a result, the independent valuation firm may revise their price after evaluating any additional evidence. However, if management continues to disagree with the price from the independent valuation firm, in light of evidence that management compiled independently and believes to be compelling, valuations are then prepared using inputs based on non-binding broker quotes obtained from independent, well-known, major financial brokers that are CLO market makers. In validating any non-binding broker quote used in this circumstance, management compares the non-binding quote to the observable market data points in addition to understanding the valuation methodologies used by the market makers. These market participants may utilize a similar methodology as the independent valuation firm to value the CLO liabilities, with the key input of expected yield determined independently based on both observable and unobservable factors. To avoid reliance on any single broker-dealer, management receives a minimum of two non-binding quotes, of which the average is used. Other Valuation Matters — For Level 3 financial assets originated, or otherwise acquired, and financial liabilities assumed during the current calendar quarter that were conducted in an orderly transaction with an unrelated party, management generally believes that the transaction price provides the most observable indication of fair value given the illiquid nature of these financial instruments, unless management is aware of any circumstances that may cause a material change in the fair value through the remainder of the reporting period. For instance, significant changes to the underlying property or its planned operations may cause material changes in the fair value of commercial real estate loans acquired, or originated, by KREF. KREF’s determination of fair value is based upon the best information available for a given circumstance and may incorporate assumptions that are management’s best estimates after consideration of a variety of internal and external factors. When an independent valuation firm expresses an opinion on the fair value of a financial instrument in the form of a range, management selects a value within the range provided by the independent valuation firm, generally the midpoint, to assess the reasonableness of management’s estimated fair value for that financial instrument. Refer to Note 15 for additional information regarding the valuation of KREF's financial assets and liabilities. Transfer of Financial Assets and Financing Agreements — KREF will, from time to time, transfer loans, securities and other assets as well as finance assets in the form of secured borrowings. In each case, management evaluates whether the transaction constitutes a sale through legal isolation of the transferred financial asset from KREF, the ability of the transferee to pledge or exchange the transferred asset without constraint and the transfer of control of the transferred asset. For transfers that constitute sales, KREF (i) recognizes the financial assets it retains and liabilities it has incurred, if any, (ii) derecognizes the financial assets it has sold, and derecognizes liabilities when extinguished and (iii) recognizes a realized gain, or loss, based upon the excess, or deficient, proceeds received over the carrying value of the transferred asset. KREF does not recognize a gain, or loss, on interests retained, if any, where management elected the fair value option prior to sale. Balance Sheet Measurement Cash and Cash Equivalents and Restricted Cash — KREF considers cash equivalents as highly liquid short-term investments with maturities of 90 days or less when purchased. KREF maintains its cash deposits with major financial institutions. Substantially all such amounts on deposit exceed insured limits. KREF must maintain sufficient cash and cash equivalents to satisfy liquidity covenants related to its secured financing agreements. However, such amounts are not restricted from use in KREF's current operations, and KREF does not present these cash and cash equivalents as restricted. As of June 30, 2024 and December 31, 2023, KREF was required to maintain unrestricted cash and cash equivalents of at least $54.4 million and $60.2 million, respectively, to satisfy its liquidity covenants (Note 5). As of June 30, 2024 and December 31, 2023, KREF had $5.5 million and $12.4 million of restricted cash held in lender-controlled bank accounts, respectively. Such amounts are presented within "Other Assets" in the Condensed Consolidated Balance Sheets (Note 8). Commercial Real Estate Loans Held-For-Investment and Allowance for Credit Losses — KREF recognizes its investments in commercial real estate loans based on management's intent, and KREF's ability, to hold those investments through their contractual maturity. Management classifies those loans that management does not intend to sell in the foreseeable future, and KREF is able to hold until maturity, as held-for-investment. Loans that are held-for-investment are carried at their aggregate outstanding principal, net of applicable (i) unamortized origination or acquisition premiums and discounts, (ii) unamortized deferred nonrefundable fees and other direct loan origination costs, and (iii) allowance for credit losses, net of write-offs of impaired loans . If a loan is determined to be impaired, management writes off the loan through a charge to the "Allowance for credit losses" and to the respective loan balance. KREF applies the interest method to amortize origination or acquisition premiums and discounts and deferred nonrefundable fees or other direct loan origination costs, or on a straight-line basis when it approximates the interest method. Loans for which management elects the fair value option at the time of origination, or acquisition, are carried at fair value on a recurring basis (Note 3). KREF recognizes and measures the allowance for credit losses under the Current Expected Credit Loss ("CECL") model which amended the previous credit loss model to reflect a reporting entity's current estimate of all expected credit losses, not only based on historical experience and current conditions, but also by including reasonable and supportable forecasts incorporating forward-looking information. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, and off-balance sheet credit exposures such as unfunded loan commitments. The allowance for credit losses required under ASU 2016-13 is deducted from the respective loans’ amortized cost basis on KREF's Condensed Consolidated Balance Sheets. The allowance for credit losses attributed to unfunded loan commitments is included in “Other liabilities” on the Condensed Consolidated Balance Sheets (Note 8). Commencing in the second quarter of 2024, KREF estimated CECL reserves using the Weighted-Average Remaining Maturity, or the WARM method, which has been identified as a loss-rate method for estimating CECL reserves under GAAP. Under the WARM method, KREF references historical loan loss data across a comparable data set and applies such loss rate to each loan over its expected remaining term, taking into consideration expected economic conditions over the relevant timeframe. To arrive at a CECL reserve using the WARM method, KREF considers various factors including (i) historical loss experience in the commercial real estate lending market, (ii) timing of expected repayments and expected loan future funding, and (iii) KREF’s view of the current and future macroeconomic environment for a reasonable and supportable forecast period. KREF derives a historical loss rate predominately based on a commercial mortgage-backed securities (“CMBS”) database with historical losses from 1998 through 2024 provided by a third party. KREF focuses on the most relevant subset of CMBS data that is determined to be the most comparable to its own portfolio. The historical loss rate is further adjusted to consider expected macroeconomic conditions over reasonable and supportable forecast periods, such as considering commercial real estate price indices, unemployment rates and market liquidity. There is significant uncertainty related to future macroeconomic conditions. Therefore, KREF also considers other loan specific credit quality factors such as the risk rating of the loan, a near-term maturity, nature of construction loans, and economic conditions specific to the property type of the underlying collateral. For collateral dependent loans for which KREF determines foreclosure of the collateral is probable, KREF measures the expected losses based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. For collateral dependent loans for which KREF determines foreclosure is not probable, KREF applies a practical expedient to estimate expected losses using the difference between the collateral’s fair value (less costs to sell the asset if repayment is expected through the sale of the collateral) and the amortized cost basis of the loan. A loan is determined to be collateral dependent if (i) a borrower or sponsor is experiencing financial difficulty, and (ii) the loan is expected to be substantially repaid through the sale of the underlying collateral. Such determination requires the use of significant judgment and can be based on several factors subject to uncertainty. Considerations used in determination of financial difficulty may include, but are not limited to, whether the borrower's operating cash flow is sufficient to cover the current and future debt service requirements, the borrower’s ability to refinance the loan, market liquidity and other circumstances that can affect the borrower’s ability to satisfy its contractual obligations under the loan agreement. KREF may adopt other acceptable alternative approaches to estimate the CECL reserve in the future based on factors such as, but not limited to, the type of loan, the underlying collateral and the availability of relevant historical market loan loss data. Commercial Real Estate Loans Held-For-Sale — Loans that KREF originates or acquires, which KREF is unable to hold, or management intends to sell or otherwise dispose of, in the foreseeable future are classified as held-for-sale and are carried at the lower of amortized cost or fair value. Real Estate Owned — To maximize recovery from a defaulted loan, KREF may assume legal title or physical possession of the underlying collateral through foreclosure or the execution of a deed in lieu of foreclosure. Foreclosed properties are initially recognized at fair value in accordance with ASC 805 on KREF's Condensed Consolidated Balance Sheets as "Real Estate Owned" when KREF assumes either legal title or physical possession. KREF’s cost basis in REO equals the estimated fair value on the acquisition date. The value of acquired REO is allocated based on the relative fair values of assets acquired and liabilities assumed, including, but not limited to, land, building, furniture and fixtures, and intangibles. REO assets held for investment, except for land, are depreciated using the straight-line method over estimated useful lives. Renovations and/or replacements that improve or extend the life of the REO asset are capitalized and depreciated over their estimated useful lives. The cost of ordinary repairs and maintenance are expensed as incurred. REO assets held for investment are evaluated for impairment on a quarterly basis. KREF considers the following factors when performing the impairment analysis: (i) significant underperformance relative to anticipated operating results; (ii) significant negative industry and economic outlook or trends; (iii) expected material costs necessary to extend the life or operate the REO asset; and (iv) KREF’s ability to hold and dispose of the REO asset in the ordinary course of business. A REO asset is considered for impairment when the sum of estimated future undiscounted cash flows to be generated by the REO asset over the estimated remaining holding period is less than the carrying value of such REO asset. An impairment charge is recorded when the carrying value of the REO exceeds the fair value. When determining the fair value of a REO asset, KREF makes certain assumptions including, but not limited to, projected operating cash flows, comparable selling prices and projected cash flows from the eventual disposition of the REO asset. REO assets are classified as held for sale in the period when they meet the criteria under ASC 360. Once a REO is classified as held for sale, depreciation is suspended and the asset is reported at the lower of its carrying value or fair value less cost to sell. The actual sales price of the REO could differ from the estimated fair value. If circumstances arise that were previously considered unlikely and, as a result, KREF decides not to sell the real estate asset previously classified as held for sale, the real estate asset is reclassified as held for investment. Upon reclassification, the real estate asset is measured at the lower of (i) its carrying amount prior to classification as held for sale, adjusted for depreciation expense that would have been recognized had the real estate been classified as held for investment, and (ii) its estimated fair value at the time of reclassification. For all REO assets (Note 4), KREF may opportunistically transact as suitable opportunities emerge. Secured Financing Agreements — KREF's secured financing agreements, including uncommitted repurchase facilities, term lending agreements, warehouse facility, asset specific financings and term loan facility, are treated as floating-rate collateralized financing arrangements carried at their contractual amounts, net of unamortized debt issuance costs (Note 5). Included within KREF's secured financing agreements is KREF's corporate revolving credit agreement ("Revolver"), which is full recourse to certain guarantor wholly-owned subsidiaries of KREF. Secured Term Loan, Net — KREF records its secured term loan at its contractual amount, net of unamortized original issuance discount and deferred financing costs (Note 7) on its Condensed Consolidated Balance Sheets. Any original issuance discount or deferred financing costs are amortized through the maturity date of the secured term loan as additional non-cash interest expense. Dividends Payable — K REF records dividends payable on its common stock and preferred stock upon declaration of such d ividends. In June 2024, KREF's board of directors declared a dividend of $0.25 per share of common stock to stockholders of record as of June 28, 2024, which was accrued in “Dividends payable” on KREF’s Condensed Consolidated Balance Sheets as of June 30, 2024 and was subsequently paid on July 15, 2024. In April 2024, KREF's board of directors declared a dividend of $0.41 per each issued and outstanding share of the Company’s 6.50% Series A Cumulative Redeemable Preferred Stock, which represents an annual dividend of $1.625 per share. The dividend was paid on June 14, 2024 to KREF’s preferred stockholders of record as of May 31, 2024. Repurchased Stock — KREF accounts for repurchases of its common stock based on the settlement date and presents repurchased stock in “Repurchased stock” on its Condensed Consolidated Balance Sheets (Note 10). Payments for stock repurchases that are not yet settled as of the reporting date are presented within “Other assets” on the Condensed Consolidated Balance Sheets. As of June 30, 2024 , all shares repurchased by KREF were retired. Income Recognition Interest Income — KREF accrues interest income on loans based on the outstanding principal amount and contractual terms of the loan. Interest income also includes origination fees, direct loan origination costs and related exit fees for loans that KREF originates, but where management did not elect the fair value option, as a yield adjustment using the interest method over the loan term, or on a straight line basis when it approximates the interest method. KREF expenses origination fees and direct loan origination costs for loans acquired, but not originated, by KREF as well as loans for which management elected the fair value option, as incurred. Revenue from Real Estate Owned Operations — Revenue from REO operations is primarily comprised of rental income, including base rent and reimbursements of property operating expenses. For leases that have fixed and measurable base rent escalations, KREF recognizes base rent on a straight-line basis over the non-cancelable lease terms. The difference between such rental income earned and the cash rent amount is recorded as straight-line rent receivable and presented within "Other assets" on the Condensed Consolidated Balance Sheets. Reimbursement of property operating expenses arises from tenant leases which provide for the recovery of certain operating expenses and real estate taxes of the respective property. This revenue is accrued in the same periods as the expenses are incurred. Rental income is presented within “ Revenue from real estate owned operations ” in the Condensed Consolidated Statements of Income. Other Income — KREF recognizes interest income earned on its cash balances and miscellaneous fee income in “Other miscellaneous income” on its Condensed Consolidated Statements of Income. Gain (Loss) on Sale of Investments — KREF recognizes the excess, or deficiency, of net proceeds received, less the net carrying value of such investments, as gains or losses, respectively. Expense Recognition Commercial Real Estate Loans, Held-For-Investment — For each loan in KREF's portfolio, management performs an evaluation, at least quarterly, of credit quality indicators of loans classified as held - for-investment using applicable loan, property, market and sponsor information obtained from borrowers, loan servicers and local market participants. Such indicators may include the net present value of the underlying collateral, property operating cash flows, the sponsor’s financial wherewithal and competency in managing the property, macroeconomic trends, and property submarket—specific economic factors. The evaluation of these credit quality indicators requires significant judgment by management to determine whether failure to collect contractual amounts is probable. If management deems that it is probable that KREF will be unable to collect all amounts owed according to the contractual terms of a loan, deterioration in credit quality of that loan is indicated. Management evaluates all available facts and circumstances that might impact KREF’s ability to collect outstanding loan balances when determining loan write-offs. These facts and circumstances may vary and may include, but are not limited to, (i) the underlying collateral performance and/or value, (ii) communications with the borrower, (iii) compliance with debt covenants, (iv) events of default by the borrower, or (v) other facts that impact the borrower’s ability to pay the contractual amounts due under the terms of the loan. If management considers a loan to be impaired, management writes off the loan through a charge to "Allowance for credit losses" based on the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral. Significant judgment is required in determining impairment and in estimating the resulting credit loss allowance, and actual losses, if any, could materially differ from those estimates. In certain circumstances, KREF may also modify terms of a loan agreement to accommodate a borrower experiencing financial difficulty. Such modifications typically include interest rate reductions, payment extension and modification of loan covenants. In conjunction with reviewing commercial real estate loans held-for-investment for impairment, KREF evaluates its commercial real estate loans at least once per quarter, assesses the risk factors of each loan, and assigns a risk rating based on a variety of factors, including, without limitation, underlying real estate performance, values of comparable properties, durability and quality of property cash flows, sponsor experience and financial wherewithal, and the existence of a risk-mitigating loan structure. Additional key considerations include debt service coverage ratios, loan structure, real estate and credit market dynamics, and risk of default or principal loss. Based on a five-point scale, KREF's loans are rated "1" through "5," from less risk to greater risk, which ratings are defined as follows: 1 (Very Low Risk); 2 (Low Risk); 3 (Medium Risk); 4 (High Risk/Potential for Loss); and 5 (Impaired/Loss Likely). Commercial Real Estate Loans, Held-For-Sale — For commercial real estate loans held-for-sale, KREF applies the lower of cost or fair value accounting and may be required, from time to time, to record a nonrecurring fair value adjustment. Accrued Interest Receivables — KREF elected not to measure an allowance for credit losses for accrued interest receivables. KREF generally writes off an accrued interest receivable balance when interest is 90 days or more past due unless the loan is both well secured and in the process of collection. Write-offs of accrued interest receivable are recognized as "Provision for (reversal of) credit losses, net" in the Condensed Consolidated Statements of Income. Tenant Receivables — KREF periodically reviews its REO tenant receivables for collectability, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. Tenant receivables, including receivables arising from the straight-lining of rents, are written-off directly when management deems that the collectability of substantially all future lease payments from a specified lease is not probable, at which point, KREF will begin recognizing revenue on a cash basis, based on actual amounts received (Note

Includes fundings on previously originated loans. (B) Includes $7.3 million of loan funding held in escrow. (C) Includes $2.5 million of cost recovery interest collections applied as a reduction to loan amortized cost during the first quarter of 2024. (D) Includes a combined $98.5 million write-off on two defaulted senior loans upon deed-in-lieu of foreclosure (Note 4) and a $37.5 million write-off on a mezzanine loan during the second quarter of June 30, 2024. As of June 30, 2024 and December 31, 2023, there were $10.7 million and $20.8 million, respectively, of unamortized origination discounts and deferred fees included in "Commercial real estate loans, held-for-investment, net" on the Condensed Consolidated Balance Sheets. D uring the three and six months ended June 30, 2024, KREF recognize d net accelerated fee income of $0.5 million relating to loan repayments. During the three and six months ended June 30, 2023, KREF recognized prepayment fee income of $0.8 million and $1.1 million and net accelerated fee income of $0.9 million and $1.2 million, respectively. KREF may enter into loan modifications that include, among other changes, incremental capital contributions or partial repayments from certain borrowers, repurposing of reserves, and a temporary partial deferral for a portion of the coupon as payment-in-kind interest (“PIK Interest”) due, which is capitalized, compounded, and added to the outstanding principal balance of the respective loans. In January 2023, KREF modified a risk-rated 5 senior office loan located in Philadelphia, PA, with an outstanding principal balance of $161.0 million. The terms of the modification included, among others, a $25.0 million principal repayment and a restructure of the $136.0 million senior loan (after the $25.0 million repayment) into (i) a $116.5 million committed senior mortgage loan (with $5.5 million in unfunded commitment) and (ii) a $25.0 million junior mezzanine note. The restructured senior loan earns a coupon rate of S+2.75% and has a new term of up to four years, assuming all extension options are exercised. The $25.0 million junior mezzanine note is subordinate to a new $41.5 million committed senior mezzanine note held by the sponsor (with $16.5 million in unfunded commitment) and was deemed uncollectible and written off in December 2022. The loan modification was accounted for as a new loan for GAAP purposes. The restructured senior loan with an outstanding principal balance of $114.3 million was risk-rated 3 as of June 30, 2024. In June 2023, KREF modified a risk-rated 5 senior office loan located in Minneapolis, MN, with an outstanding principal balance of $194.4 million. The terms of the modification included, among others, a restructure of the $194.4 million senior loan into (i) a $120.0 million senior mortgage loan (fully funded) and (ii) a $79.4 million mezzanine note (with $5.0 million in unfunded commitment). The restructured senior loan earns a coupon rate of S+2.25% and the mezzanine note earns a fixed 4.5% PIK interest rate. Post modification, the whole loan’s maximum maturity is July 2025, assuming all extension options are exercised. The restructured whole loan with an outstanding principal balance of $194.4 million was risk-rated 5 as of June 30, 2024. In September 2023, KREF modified a risk-rated 4 senior office loan located in Chicago, IL, with an outstanding principal balance of $118.4 million. The terms of the modification included, among others, a $15.0 million principal repayment, a $15.0 million reduction in unfunded loan commitment, and a restructure of the $103.4 million senior loan (after the $15.0 million repayment) into (i) a $105.0 million committed senior mortgage loan (with $16.6 million in unfunded commitment) and (ii) a $15.0 million subordinated note which is subordinate to a new $18.5 million sponsor interest. The restructured senior loan earns a coupon rate of S+2.25% and has a new term of five years. The $15.0 million subordinated note was deemed uncollectible and written off. The loan modification was accounted for as a new loan for GAAP purposes. The restructured senior loan with an outstanding principal balance of $88.4 million was risk-rated 3 as of June 30, 2024. In June 2024, KREF modified a risk-rated 5 mezzanine office loan located in Boston, MA, with an outstanding principal balance of $37.5 million. The terms of the modification included, among others, a restructure of the mezzanine loan into (i) a $12.5 million senior mezzanine note and (ii) a $25.0 million junior mezzanine note which is subordinate to a new $10.0 million sponsor interest. The senior and junior mezzanine notes earn a PIK interest rate of S+7.0% and have a maximum maturity of February 2028. Both mezzanine notes were deemed uncollectible and written off in June 2024. Loan Risk Ratings — As further described in Note 2, KREF evaluates its commercial real estate loan portfolio at least once per quarter. In conjunction with its commercial real estate loan portfolio review, KREF assesses the risk factors of each loan and assigns a risk rating based on a variety of factors. Loans are rated “1” (Very Low Risk) through “5” (Impaired/Loss Likely), which ratings are defined in Note 2. The following tables summarize the carrying value of the loan portfolio based on KREF's internal risk ratings: June 30, 2024 December 31, 2023 Risk Rating Number of Loans (A) Carrying Value Total Loan Exposure (B) Total Loan Exposure % Number of Loans (A) Carrying Value Total Loan Exposure (B) Total Loan Exposure % 1 — $ — $ — — % — $ — $ — — % 2 2 19,832 58,386 1 2 19,392 57,925 1 3 54 5,913,015 5,923,297 90 60 6,493,506 6,511,894 86 4 4 399,275 399,798 6 4 325,286 476,112 6 5 1 190,113 194,400 3 3 505,364 512,105 7 Total loan receivable 61 $ 6,522,235 $ 6,575,881 100 % 69 $ 7,343,548 $ 7,558,036 100 % Allowance for credit losses (110,583) (210,470) Loan receivable, net $ 6,411,652 $ 7,133,078 * Numbers presented may not foot due to rounding.

The CECL provision of $37.8 million for the six months ended June 30, 2024 was primarily due to additional reserves on a risk-rated 5 senior loan predominantly in the office sector, as well as macroeconomic conditions. KREF had a risk-rated 5 senior office loan located in Minneapolis, MN, originated in November 2017. The property is located in a challenged leasing market. As of June 30, 2024, the loan had an outstanding principal balance of $194.4 million, an unfunded commitment of $5.0 million and an amortized cost of $190.1 million. In June 2023, KREF restructured the $194.4 million senior loan into (i) a $120.0 million senior mortgage loan (fully funded) and (ii) a $79.4 million mezzanine note (with $5.0 million in unfunded commitment). The restructured senior loan earns a coupon rate of S+2.25% and the mezzanine note earns a fixed 4.5% PIK interest rate. Post modification, the whole loan’s maximum maturity is July 2025, assuming all extension options are exercised. Since June 2023, the senior loan has been on nonaccrual status. During the three and six months ended June 30, 2024, KREF recognized $2.3 million and $4.6 million, respectively, of interest income on this loan. The 5-rated loan was determined to be collateral dependent as of June 30, 2024. KREF estimated expected losses based on the loan’s collateral fair value, which was determined by applying a capitalization rate of 9.3% and a discount rate of 10.0%. As of June 30, 2023, the allowance for credit losses was $227.9 million. The CECL provision of $116.8 million for the six months ended June 30, 2023 was primarily due to additional reserves on risk-rated 5 senior loans predominantly in the office sector, as well as macroeconomic conditions. Concentration of Credit Risk — The following tables present the geographies and property types of collateral underlying KREF's commercial real estate loans as a percentage of the loans' principal amounts: June 30, 2024 December 31, 2023 June 30, 2024 December 31, 2023 Geography Collateral Property Type California 17.8 % 17.7 % Multifamily 45.9 % 41.9 % Texas 17.0 15.3 Office 20.1 22.2 Massachusetts 12.1 10.4 Industrial 14.2 14.5 Florida 7.9 8.7 Life Science 10.5 10.2 Virginia 7.6 7.7 Hospitality 3.7 5.0 Washington D.C. 4.8 6.3 Self-Storage 2.3 1.7 North Carolina 4.7 4.1 Student Housing 1.7 1.5 Pennsylvania 4.4 3.5 Single Family Rental 1.1 0.9 New York 3.8 6.1 Mixed Use 0.5 — Washington 3.5 4.2 Condo (Residential) — 2.0 Minnesota 2.9 2.6 Retail — 0.1 Arizona 2.8 3.3 Total 100.0 % 100.0 % Georgia 2.8 2.7 Nevada 2.3 2.1 Illinois 1.6 1.4 Colorado 1.3 1.1 Other U.S. 2.7 2.8 Total 100.0 % 100.0 %

Real Estate [Abstract]
Real Estate Owned	Real Estate Owned Real Estate Owned, Held For Investment Portland Retail / Redevelopment — In 2015, KREF originated a $177.0 million senior loan secured by a retail property in Portland, OR. In December 2021, KREF took title to the retail property and accounted for the property on a consolidated basis (Note 9). The transaction was accounted for as an asset acquisition under ASC 805. Accordingly, KREF recorded the property on the Condensed Consolidated Balance Sheets as REO with a carrying value of $78.6 million, which included the estimated fair value of the property. KREF contributed a portion of the REO asset with a carrying value of $68.9 million to a joint venture (the "REO JV") with a third party local developer (“JV Partner”), whereby KREF had a 90% interest and the JV Partner had a 10% interest. The JV Partner's interest in the property was presented within "Noncontrolling interests in equity of consolidated joint ventures" on the Condensed Consolidated Balance Sheets. In September 2023, the REO JV submitted a conceptual master plan to the City of Portland’s Bureau of Development Services in an application for a Design Advice Request (DAR) meeting with the City's Design Commission. Mountain View Office — In 2021, KREF co-originated with a KKR affiliate a committed $362.8 million senior loan secured by an office property in Mountain View, CA. KREF's interest was 68.9% of the loan or $250.0 million. As of March 31, 2024, the KREF loan had a risk rating of 5 with an amortized cost of $198.9 million. In June 2024, KREF and the KKR affiliate took title to the office property through a deed-in-lieu of foreclosure and KREF accounted for the property on a consolidated basis (Note 9). The transaction was accounted for as an asset acquisition under ASC 805. Accordingly, KREF recorded the property and its net assets on the Condensed Consolidated Balance Sheets with an estimated fair value of $174.7 million, which included $175.0 million of REO held for investment and ($0.3) million of net working capital. As a result, KREF recognized a $79.9 million loan write-off for the difference between KREF's interest in the amortized cost of the foreclosed loan and KREF's share of the fair value of the REO’s net assets and closing costs. The KKR affiliate's interest in the property was 31.1%, or $54.3 million as of June 30, 2024, and was presented within "Noncontrolling interests in equity of consolidated joint ventures" on the Condensed Consolidated Balance Sheets. Real Estate Owned, Held For Sale Philadelphia Office / Garage — In 2019, KREF originated a $182.6 million senior loan secured by an office portfolio in Philadelphia, PA. As of September 30, 2023, the loan had a risk rating of 5 with an amortized cost of $151.1 million. In December 2023, KREF received a $6.0 million partial repayment and then took title to the office property through a deed-in-lieu of foreclosure. The transaction was accounted for as an asset acquisition under ASC 805. Accordingly, KREF recorded the portfolio and its net assets on the Condensed Consolidated Balance Sheets with an estimated fair value of $86.4 million, which included $1.3 million of cash received and $76.5 million, $24.6 million and $15.9 million allocated to REO held for sale, lease intangible and other assets, and leasing and other liabilities, respectively. As a result, KREF recognized a $58.7 million loan write-off for the difference between the amortized cost of the foreclosed loan and the fair value of the REO’s net assets. In June 2024, KREF sold a portion of the portfolio for a gross sales price of $41.0 million and recognized a realized loss of $0.6 million after buyer credits and closing costs. Concurrently, KREF provided financing to the buyer through a senior loan with an outstanding principal balance of $30.1 million ($83.7 million total commitment) as of June 30, 2024. The senior loan earns a coupon rate of S+4.3% and has a maximum maturity of June 2029, assuming all extension options are exercised. The senior loan is presented within “Commercial real estate loans, held-for-investment, net” on the Condensed Consolidated Balance Sheets. As of June 30, 2024, the remaining REO assets and liabilities met the criteria to be classified as held for sale under ASC 360. As such, depreciation and amortization on the REO and related lease intangibles were suspended. Leases — KREF assumed certain legacy lease arrangements upon the acquisition of the REO assets and entered into lease arrangements during the hold period. These arrangements entitle KREF to receive contractual rent payments during the lease periods and tenant reimbursements for certain property operating expenses, including common area costs, insurance, utilities and real estate taxes. KREF elects the practical expedient to not separate the lease and non-lease components of the rent payments and accounts for these lease arrangements as operating leases.

As of June 30, 2024 and December 31, 2023, the percentage of the outstanding principal of the collateral sold and not borrowed under these repurchase agreements, or average "haircut" weighted by outstanding principal of collateral, was 30.9% and 33.8%, respectively (or 28.5% and 32.2%, respectively, if KREF had borrowed the maximum amount approved by its repurchase agreement counterparties as of such dates). (E) The term loan facility provides asset-based financing on a non-mark-to-market basis with match-term up to five years, with additional two-year extension available to KREF. (F) In May 2024, the lender assigned its rights and obligations under the KREF Lending IX Facility to another financial institution. In connection with the assignment, KREF's borrowing capacity under the facility was amended to $701.1 million. (G) As of June 30, 2024 , the revolver carrying value excluded $3.3 million unamortized d ebt issuance costs presented within "Other assets" on KREF's Condensed Consolidated B alance Sheets. As of June 30, 2024 and December 31, 2023, KREF had outstanding repurchase agreements, term lending agreements and warehouse facility where the amount at risk with any individual counterparty, or group of related counterparties, exceeded 10.0% of KREF’s stockholders' equity. The amount at risk under these arrangements is the net counterparty exposure, defined as the excess of the carrying amount (or market value, if higher than the carrying amount, for repurchase agreements) of the assets sold under agreement to repurchase, including accrued interest plus any cash or other assets on deposit to secure the repurchase obligation, over the amount of the repurchase liability, adjusted for accrued interest. The following table summarizes certain characteristics of KREF's repurchase agreements where the amount at risk with any individual counterparty, or group of related counterparties, exceeded 10.0% of KREF’s stockholders' equity as of June 30, 2024 and December 31, 2023: Outstanding Net Counterparty Exposure Percent of Stockholders' Equity Weighted Average Life (Years) (A) June 30, 2024 Morgan Stanley $ 986,475 $ 333,511 24.0 % 2.2 Wells Fargo 571,012 215,159 15.5 2.2 Goldman Sachs 309,538 167,441 12.1 2.4 Total / Weighted Average $ 1,867,025 $ 716,111 51.6 % 2.3 December 31, 2023 Wells Fargo $ 646,559 $ 248,891 17.7 % 2.7 Morgan Stanley 483,339 203,080 14.5 1.6 KREF Lending IX 696,605 172,462 12.3 3.1 Goldman Sachs 347,329 170,236 12.1 2.9 Total / Weighted Average $ 2,173,832 $ 794,669 56.6 % 2.6 (A) Average weighted by the outstanding principal of borrowings under the secured financing agreement. Debt obligations included in the tables above are obligations of KREF’s consolidated subsidiaries, which own the related collateral, and such collateral is generally not available to other creditors of KREF. While KREF is generally not required to post margin under certain repurchase agreement terms for changes in general capital market conditions such as changes in credit spreads or interest rates, KREF may be required to post margin for changes in conditions to specific loans that serve as collateral for those repurchase agreements. Such changes may include declines in the appraised value of property that secures a loan or a negative change in the borrower's ability or willingness to repay a loan. To the extent that KREF is required to post margin, KREF's liquidity could be significantly impacted.

(D) Borrowings under these repurchase agreements are collateralized by senior loans, held-for-investment, and bear interest equal to the sum of (i) Term SOFR, and (ii) a financing spread. As of June 30, 2024 and December 31, 2023, the percentage of the outstanding principal of the collateral sold and not borrowed under these repurchase agreements, or average "haircut" weighted by outstanding principal of collateral, was 30.9% and 33.8%, respectively (or 28.5% and 32.2%, respectively, if KREF had borrowed the maximum amount approved by its repurchase agreement counterparties as of such dates). (E) The term loan facility provides asset-based financing on a non-mark-to-market basis with match-term up to five years, with additional two-year extension available to KREF. (F) In May 2024, the lender assigned its rights and obligations under the KREF Lending IX Facility to another financial institution. In connection with the assignment, KREF's borrowing capacity under the facility was amended to $701.1 million. (G) As of June 30, 2024 , the revolver carrying value excluded $3.3 million unamortized d ebt issuance costs presented within "Other assets" on KREF's Condensed Consolidated B alance Sheets. As of June 30, 2024 and December 31, 2023, KREF had outstanding repurchase agreements, term lending agreements and warehouse facility where the amount at risk with any individual counterparty, or group of related counterparties, exceeded 10.0% of KREF’s stockholders' equity. The amount at risk under these arrangements is the net counterparty exposure, defined as the excess of the carrying amount (or market value, if higher than the carrying amount, for repurchase agreements) of the assets sold under agreement to repurchase, including accrued interest plus any cash or other assets on deposit to secure the repurchase obligation, over the amount of the repurchase liability, adjusted for accrued interest. The following table summarizes certain characteristics of KREF's repurchase agreements where the amount at risk with any individual counterparty, or group of related counterparties, exceeded 10.0% of KREF’s stockholders' equity as of June 30, 2024 and December 31, 2023: Outstanding Net Counterparty Exposure Percent of Stockholders' Equity Weighted Average Life (Years) (A) June 30, 2024 Morgan Stanley $ 986,475 $ 333,511 24.0 % 2.2 Wells Fargo 571,012 215,159 15.5 2.2 Goldman Sachs 309,538 167,441 12.1 2.4 Total / Weighted Average $ 1,867,025 $ 716,111 51.6 % 2.3 December 31, 2023 Wells Fargo $ 646,559 $ 248,891 17.7 % 2.7 Morgan Stanley 483,339 203,080 14.5 1.6 KREF Lending IX 696,605 172,462 12.3 3.1 Goldman Sachs 347,329 170,236 12.1 2.9 Total / Weighted Average $ 2,173,832 $ 794,669 56.6 % 2.6 (A) Average weighted by the outstanding principal of borrowings under the secured financing agreement. Debt obligations included in the tables above are obligations of KREF’s consolidated subsidiaries, which own the related collateral, and such collateral is generally not available to other creditors of KREF. While KREF is generally not required to post margin under certain repurchase agreement terms for changes in general capital market conditions such as changes in credit spreads or interest rates, KREF may be required to post margin for changes in conditions to specific loans that serve as collateral for those repurchase agreements. Such changes may include declines in the appraised value of property that secures a loan or a negative change in the borrower's ability or willingness to repay a loan. To the extent that KREF is required to post margin, KREF's liquidity could be significantly impacted. Both KREF and its lenders work cooperatively to monitor the performance of the properties and operations related to KREF's loan investments to mitigate investment-specific credit risks. Additionally, KREF incorporates terms in the loans it originates to further mitigate risks related to loan nonperformance. Activity — For the six months ended June 30, 2024, the activity related to the carrying value of KREF’s secured financing agreements were as follows: Secured Financing Agreements, Net Balance as of December 31, 2023 $ 3,782,419 Principal borrowings 266,607 Principal repayments/sales (768,335) Deferred debt issuance costs (1,991) Amortization of deferred debt issuance costs 6,973 Balance as of June 30, 2024 $ 3,285,673 Maturities — KREF’s secured financing agreements, term loan facility and other consolidated debt obligations in place as of June 30, 2024 had contractual maturities as follows: Year Nonrecourse (A) Recourse (A)(B) Total 2025 $ 211,317 $ 53,689 $ 265,006 2026 1,253,931 332,521 1,586,452 2027 951,264 361,416 1,312,680 Thereafter 128,199 — 128,199 $ 2,544,711 $ 747,626 $ 3,292,337 (A) Represents the earlier of (i) the maximum maturity of the underlying loans pledged as collateral or (ii) the maximum maturity of the respective financing agreements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Equity Method Investments	Consolidation and Equity Method Investments Collateralized Loan Obligations — KREF consolidates CLOs when it determines that the CLO issuers, wholly-owned subsidiaries of KREF, are VIEs and that KREF is the primary beneficiary of such VIEs (Note 6). Management considers KREF to be the primary beneficiary of the CLO issuers as KREF has the ability to control the most significant activities of the CLO issuers, the obligation to absorb losses, and the right to receive benefits of the CLOs through the subordinate interests the CLO issuers own. Consolidated Real Estate Owned Joint Ventures Portland Retail / Redevelopment — In December 2021, KREF took title to a Portland retail property and contributed a portion of the REO asset to a REO JV with a JV Partner, where KREF had a 90% interest and the JV Partner had a 10% interest. Management determined the REO JV to be a VIE as the REO JV has insufficient equity-at-risk and concluded that KREF is the primary beneficiary of the REO JV as KREF holds decision-making power over the activities that most significantly impact the economic performance and has the obligation to absorb losses, or the right to receive benefits, that could be potentially significant to the REO JV. As of June 30, 2024, the REO JV held REO assets with a net carrying value of $77.4 million. KREF has priority of distributions up to $81.6 million before the JV Partner can participate in the economics of the REO JV. Mountain View Office — In June 2024, KREF and a KKR affiliate took title to a Mountain View office property. The property was held in a joint venture where KREF and the KKR affiliate held a 68.9% and 31.1% interest, respectively and shared decision-making. Management determined the joint venture to be a VIE as the joint venture was established with non-substantive voting rights and concluded that KREF is the primary beneficiary of the joint venture as KREF holds decision-making power over the activities that most significantly impact the economic performance and has the obligation to absorb losses, or the right to receive benefits, that could be potentially significant to the joint venture. Equity Method Investment — Real Estate Asset In 2021, KREF co-originated with a KKR affiliate a $188.0 million senior loan secured by a life science property in Seattle, WA. KREF's interest was 74.6% of the loan or $140.3 million. As of March 31, 2024, the KREF loan had a risk rating of 5 with an amortized cost of $114.2 million. In June 2024, KREF received a $14.3 million partial repayment, then along with the KKR affiliate, took title to the life science property through a deed-in-lieu of foreclosure under a Tenant-in-Common ("TIC") agreement. Under the TIC agreement, KREF and the KKR affiliate held an economic interest of 74.6% and 25.4%, respectively, and shared decision-making. Under ASC 970-810, KREF accounted for the TIC agreement as an undivided interest in the property and recorded an $82.0 million equity method investment based on KREF’s share of the fair value of the property’s net assets. As a result, KREF recognized a $18.6 million loan write-off for the difference between the amortized cost of the foreclosed loan and KREF’s share of the fair value of the property’s net assets and closing costs. Equity Method Investment — CMBS B-Pieces As of June 30, 2024, KREF held a 3.5% interest in RECOP I, an unconsolidated VIE of which KREF is not the primary beneficiary, at its fair value of $35.3 million. The aggregator vehicle in which KREF invests is controlled and advised by affiliates of the Manager. RECOP I primarily acquired junior tranches of CMBS newly issued by third parties. KREF will not pay any fees to RECOP I, but KREF bears its pro rata share of RECOP I's expenses. KREF reported its share of the net asset value of RECOP I in its Condensed Consolidated Balance Sheets, presented as “Equity method investment, CMBS B-Pieces” and its share of net income, presented as “Income (loss) from equity method investment” in the Condensed Consolidated Statements of Income.

Common Stock — As further described below, since December 31, 2021, KREF issued the following shares of common stock: Pricing Date Shares Issued (A) Net Proceeds As of December 31, 2021 64,759,200 $ 1,282,734 February 2022 (B) 68,817 1,426 March 2022 6,494,155 133,845 June 2022 2,750,000 53,653 August 2022 (B) 271,641 5,300 As of December 31, 2023 and June 30, 2024 74,343,813 $ 1,476,958 (A) Excludes 975,091 net shares of common stock issued to-date in connection with vested restricted stock units. (B) Represents shares issued under the ATM. During the six months ended June 30, 2024 and 2023, 19,348 and 11,050 shares of common stock were issued related to the vesting of restricted stock units. Upon any payment of shares as a result of restricted stock unit vesting, the related tax withholding obligation will generally be satisfied by KREF, reducing the number of shares to be delivered by a number of shares necessary to satisfy the related applicable tax withholding obligation. Refer to Note 11 for further detail. In June 2024, KREF retired 5,985,696 shares of repurchased common stock. As of June 30, 2024, there were 69,333,208 common shares issued and outstanding, which included 975,091 net shares of common stock issued in connection with vested restricted stock units. KKR and affiliates beneficially owned 10,000,001 shares, or 14.4% of KREF's outstanding common stock as of June 30, 2024 and December 31, 2023. Share Repurchase Program — Under KREF's current share repurchase program, which has no expiration date, KREF may repurchase up to an aggregate of $100.0 million of its common stock effective as of February 3, 2023, of which up to $50.0 million may be repurchased under a pre-set trading plan meeting the requirements of Rule 10b5-1 under the Exchange Act, and provide for repurchases of common stock when the market price per share is below book value per share (calculated in accordance with GAAP as of the end of the most recent quarterly period for which financial statements are available), and the remaining $50.0 million may be used for repurchases in the open market, pursuant to pre-set trading plans meeting the requirements of Rule 10b5-1 under the Exchange Act, in privately negotiated transactions or otherwise. The timing, manner, price and amount of any common stock repurchases will be determined by KREF in its discretion and will depend on a variety of factors, including legal requirements, price, liquidity and economic considerations, and market conditions. The program does not require KREF to repurchase any specific number of shares of common stock. The program does not have an expiration date and may be suspended, modified or discontinued at any time. During the six months ended June 30, 2024, KREF did not repurchase any of its common stock under the repurchase program. As of June 30, 2024, KREF had $100.0 million of remaining capacity to repurchase shares under the program. At the Market Stock Offering Program — In February 2019, KREF entered into an equity distribution agreement with certain sales agents, pursuant to which KREF may sell, from time to time, up to an aggregate sales price of $100.0 million of its common stock pursuant to a continuous offering program (the “ATM”). Sales of KREF’s common stock made pursuant to the ATM may be made in negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended. The timing and amount of actual sales will depend on a variety of factors including market conditions, the trading price of KREF’s common stock, KREF’s capital needs, and KREF’s determination of the appropriate sources of funding to meet such needs. During the six months ended June 30, 2024, KREF did not issue or sell any shares of common stock under the ATM. As of June 30, 2024, $93.2 million remained available for issuance under the ATM. 6.50% Series A Cumulative Redeemable Preferred Stock — The perpetual Series A Preferred Stock is redeemable, at KREF's option, at a liquidation price of $327.8 million, or $25.00 per share, plus accrued and unpaid dividends commencing in April 2026. Dividends on the Series A Preferred Stock are payable quarterly at a rate of 6.50% per annum of the $25.00 liquidation preference, which is equivalent to $1.625 per annum per share. With respect to dividend rights and liquidation, the Series A Preferred Stock ranks senior to KREF's common stock. Noncontrolling Interests — Noncontrolling interests represent an interest held by investors other than KREF in consolidated joint ventures that hold KREF’s REO investments. KREF and the noncontrolling interest holders typically contribute to the joint ventures' ongoing operating shortfalls and capital expenditures on a pari passu basis. Distributions from the joint ventures are allocated between KREF and the noncontrolling interest holders based on contractual terms and waterfalls as outlined in the joint venture agreements. Dividends — During the six months ended June 30, 2024 and 2023, KREF's board of directors declared the following dividends on shares of its common stock: Amount Declaration Date Record Date Payment Date Per Share Total 2024 February 1, 2024 March 28, 2024 April 15, 2024 $ 0.25 $ 17,328 June 13, 2024 June 28, 2024 July 15, 2024 0.25 17,333 $ 34,661 2023 March 17, 2023 March 31, 2023 April 14, 2023 $ 0.43 $ 29,711 June 15, 2023 June 30, 2023 July 14, 2023 0.43 29,716 $ 59,427 During the six months ended June 30, 2024 and 2023, KREF's board of directors declared the following dividends on shares of its Series A Preferred Stock: Amount Declaration Date Record Date Payment Date Per Share Total 2024 February 1, 2024 February 29, 2024 March 15, 2024 $ 0.41 $ 5,326 April 19, 2024 May 31, 2024 June 14, 2024 0.41 5,326 $ 10,652 2023 February 3, 2023 February 28, 2023 March 15, 2023 $ 0.41 $ 5,326 April 21, 2023 May 31, 2023 June 15, 2023 0.41 5,326 $ 10,652

Share-Based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation KREF is externally managed by the Manager and does not currently have any employees. However, as of June 30, 2024, certain individuals employed by the Manager and affiliates of the Manager and certain members of KREF's board of directors were compensated, in part, through the issuance of stock-based awards. As of June 30, 2024, KREF had 1,143,190 restricted stock unit (“RSU”) awards outstanding under the KKR Real Estate Finance Trust Inc. 2016 Omnibus Incentive Plan that was adopted on February 12, 2016 and amended and restated on November 17, 2016 (the "Incentive Plan") to certain members of KREF’s board of directors and employees of the Manager or its affiliates, none of whom are KREF employees. RSUs awarded to employees of the Manager or its affiliates, generally vest over three consecutive one-year periods and awards to certain members of KREF's board of directors generally vest over a one-year period, pursuant to the terms of the respective award agreements and the terms of the Incentive Plan. As of June 30, 2024, all outstanding RSU awards were entitled to nonforfeitable dividends during the vesting periods, at the same rate as those declared on the common stock. The following table summarizes the activity in KREF’s outstanding RSUs and the weighted-average grant date fair value per RSU: Restricted Stock Units Weighted Average Grant Date Fair Value Per RSU (A) Unvested as of December 31, 2023 1,147,927 $ 14.49 Granted 56,350 9.76 Vested (48,370) 11.37 Forfeited / cancelled (12,717) 15.27 Unvested as of June 30, 2024 1,143,190 $ 14.38 (A) The grant-date fair value is based upon the closing price of KREF’s common stock at the date of grant. KREF expects the unvested RSUs outstanding to vest during the following years: Year Restricted Stock Units 2024 502,949 2025 432,324 2026 207,917 Total 1,143,190 KREF recognizes the compensation cost of RSUs awarded to employees of the Manager, or one or more of its affiliates, on a straight-line basis over the awards’ term at their grant date fair value, consistent with the RSUs awarded to certain members of KREF's board of directors. During the three and six months ended June 30, 2024, KREF recognized $2.2 million and $4.5 million respectively, of stock-based compensation expense included in “General and administrative” expense in the Condensed Consolidated Statements of Income. During the three and six months ended June 30, 2023, KREF recognized $2.2 million and $4.3 million respectively, of stock-based compensation expense included in “General and administrative” expense in the Condensed Consolidated Statements of Income. As of June 30, 2024, there was $10.7 million of total unrecognized stock-based compensation expense related to unvested share-based compensation arrangements. This cost is expected to be recognized over a weighted average period of 1.0 year. During the six months ended June 30, 2024 and 2023, KREF declared $0.6 million and $0.8 million, respectively, of nonforfeitable dividends on unvested RSUs. Such nonforfeitable dividends were deducted from “Retained earnings (Accumulated deficit)” in the Condensed Consolidated Statement of Changes in Equity. Directors and Officers Deferral Plan — In March 2022, KREF's board of directors adopted the KKR Real Estate Finance Trust Inc. Directors and Officers Deferral Plan (the “Deferral Plan”). Pursuant to the Deferral Plan, participants may elect to defer receipt of all or a portion of any shares of KREF’s common stock issuable upon vesting of any RSU granted to such participant in 25% increments. Deferred stock units (“DSU”) credited to a participant are non-voting but shall be entitled to dividend equivalent payments upon payment of dividends on shares of KREF’s common stock in the same form and amount equal to the amount of such dividends and are not subject to deferral under the Deferral Plan. During the six months ended June 30, 2024, 29,022 vested RSUs were deferred under the Deferral Plan. As of June 30, 2024, there were 101,730 DSUs outstanding. Upon any payment of shares as a result of restricted stock unit vesting, the related tax withholding obligation will generally be satisfied by KREF, reducing the number of shares to be delivered by a number of shares necessary to satisfy the related applicable tax withholding obligation. The amount results in a cash payment related to this tax liability and a corresponding reduction to additional paid-in capital in the Condensed Consolidated Statement of Changes in Equity. No shares were delivered for vested RSUs during the six months ended June 30, 2024. Refer to Note 14 for additional information regarding the Incentive Plan.

Earnings Per Share [Abstract]
Earnings (Loss) per Share	Earnings (Loss) per Share Earnings (Loss) per Share — KREF calculates its basic EPS using the two-class method, which defines unvested share-based payment awards that contain nonforfeitable rights to dividends as participating securities. Under the two-class method earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights. Basic EPS, is calculated by dividing net income (loss) attributable to common stockholders by the weighted average common stock outstanding for the period. KREF presents diluted EPS under the more dilutive of the treasury stock and if-converted methods or the two-class method. Under the treasury stock and if-converted methods, the denominator includes weighted average common stock outstanding plus the incremental dilutive shares issuable from restricted stock units and an assumed conversion of the Convertible Notes (for the periods in which such notes were outstanding). The numerator includes any changes in income (loss) that would result from the assumed conversion of these potential shares of common stock. For the six months ended June 30, 2024 and 2023, 22,967 and 10,213 weighted average unvested RSUs, respectively, were excluded from the calculation of diluted EPS because the effect was anti-dilutive. The following table illustrates the computation of basic and diluted EPS for the three and six months ended June 30, 2024 and 2023: Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Earnings Net Income (Loss) $ 25,832 $ (20,028) $ 22,724 $ (45,105) Less: Preferred stock dividends 5,326 5,326 10,652 10,652 Less: Participating securities' share in earnings 283 418 588 825 Net income (loss) attributable to common stockholders, basic and diluted $ 20,223 $ (25,772) $ 11,484 $ (56,582) Shares Weighted average common shares outstanding 69,328,530 69,103,268 69,321,195 69,099,162 Add: Deferred stock units 94,714 12,386 83,711 6,227 Diluted weighted average common shares outstanding 69,423,244 69,115,654 69,404,906 69,105,389 Net income (loss) attributable to common stockholders, per: Basic and Diluted common share $ 0.29 $ (0.37) $ 0.17 $ (0.82)

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies As of June 30, 2024, KREF was subject to the following commitments and contingencies: Litigation — From time to time, KREF may be involved in various claims and legal actions arising in the ordinary course of business. KREF establishes an accrued liability for legal proceedings only when those matters present loss contingencies that are both probable and reasonably estimable. As of June 30, 2024, KREF was not involved in any material legal proceedings regarding claims or legal actions against KREF. Indemnifications — In the normal course of business, KREF enters into contracts that contain a variety of representations and warranties that provide general indemnifications and other indemnities relating to contractual performance. In addition, certain of KREF’s subsidiaries have provided certain indemnities relating to environmental and other matters and has provided nonrecourse carve-out guarantees for fraud, willful misconduct and other customary wrongful acts, each in connection with the financing of certain real estate investments that KREF has made. KREF’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against KREF that have not yet occurred. However, KREF expects the risk of material loss to be low. Capital Commitments — As of June 30, 2024, KREF had future funding commitments of $573.6 million related to its investments in commercial real estate loans. These future funding commitments primarily relate to construction projects, capital improvements, tenant improvements and leasing commissions. Generally, funding commitments are subject to certain conditions that must be met, such as customary construction draw certifications, minimum credit metrics or executions of new leases before advances are made to the borrower. In January 2017, KREF committed $40.0 million to invest in an aggregator vehicle alongside RECOP I. The two-year investment period for RECOP I ended in April 2019. As of June 30, 2024, KREF had a remaining commitment of $4.3 million to RECOP I. Macroeconomic Environment — The Federal Reserve has raised interest rates eleven times since January 2022. Higher interest rates imposed by the Federal Reserve to address inflation may adversely impact real e state asset values and increase our interest expense, which expense may not be fully offset by any resulting increase in interest income, and may lead to decreased prepayments from KREF's borrowers and an increase in the number of KREF's borrowers who exercise extension options. The Federal Reserve has indicated that it may decrease interest rates in 2024. In a period of declining interest rates, our interest income on floating-rate investments would generally decrease, while any decrease in the interest we are charged on our floating-rate debt may be subject to floors and may not compensate for such decrease in interest income.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Management Agreement — The Management Agreement between KREF and the Manager is a three-year agreement that provides for automatic one-year renewal periods starting October 8, 2017, subject to certain termination and nonrenewal rights, which in the case of KREF are exercisable by a two-thirds vote by the independent directors of KREF's board of directors. If the independent directors of KREF's board of directors decline to renew the Management Agreement other than for cause, KREF is required to pay the Manager a termination fee equal to three times the total 24-month trailing average annual management fee and incentive compensation earned by the Manager through the most recently completed calendar quarter. For administrative efficiency purposes, the Management Agreement was amended in August 2019 to change the expiration date of each automatic renewal period from October 7th to December 31st. Pursuant to the Management Agreement, the Manager, as agent to KREF and under the supervision of KREF's board of directors, manages the investments, subject to investment guidelines approved by KREF's board of directors; financing activities; and day-to-day business and affairs of KREF and its subsidiaries. For its services to KREF, the Manager is entitled to a quarterly management fee equal to the greater of $62,500 or 0.375% of weighted average adjusted equity and quarterly incentive compensation equal to 20.0% of the excess of (a) the trailing 12-month distributable earnings (before incentive compensation payable to the Manager) over (b) 7.0% of the trailing 12-month weighted average adjusted equity (“Hurdle Rate”), less incentive compensation KREF already paid to the Manager with respect to the first three calendar quarters of such trailing 12-month period. The quarterly incentive compensation is calculated and paid in arrears with a one-quarter lag. Adjusted equity generally represents the proceeds received by KREF and its subsidiaries from equity issuances, without duplication and net of offering costs, and distributable earnings, reduced by distributions, equity repurchases, and incentive compensation paid. Distributable earnings generally represent the net income, or loss, attributable to equity interests in KREF and its subsidiaries, without duplication, as well as realized losses not otherwise included in such net income, or loss, excluding non-cash equity compensation expense, incentive compensation, depreciation and amortization and unrealized gains or losses, from and after the effective date to the end of the most recently completed calendar quarter. KREF's board of directors, after majority approval by independent directors, may also exclude one-time events pursuant to changes in GAAP and certain material non-cash income or expense items from distributable earnings. For purposes of calculating incentive compensation, adjusted equity excludes: (i) the effects of equity issued by KREF and its subsidiaries that provides for fixed distributions or other debt characteristics and (ii) unrealized provision for (reversal of) credit losses. KREF is also required to reimburse the Manager or its affiliates for documented costs and expenses incurred by it and its affiliates on behalf of KREF, except those specifically required to be borne by the Manager under the Management Agreement. The Manager is responsible for, and KREF does not reimburse the Manager or its affiliates for, the expenses related to investment personnel of the Manager and its affiliates who provide services to KREF. However, KREF does reimburse the Manager for KREF's allocable share of compensation paid to certain of the Manager’s non-investment personnel, based on the percentage of time devoted by such personnel to KREF's affairs. Incentive Plan — KREF's compensation committee or board of directors may administer the Incentive Plan, which provides for awards of stock options; stock appreciation rights; restricted stock; RSUs; limited partnership interests of KKR Real Estate Finance Holdings L.P. (the "Operating Partnership"), a wholly owned subsidiary of KREF, that are directly or indirectly convertible into or exchangeable or redeemable for shares of KREF's common stock pursuant to the limited partnership agreement of the Operating Partnership (“OP Interests”); awards payable by (i) delivery of KREF's common stock or other equity interests, or (ii) reference to the value of KREF's common stock or other equity interests, including OP Interests; cash-based awards; or performance compensation awards. No more than 7.5% of the issued and outstanding shares of common stock on a fully diluted basis, assuming the exercise of all outstanding stock options granted under the Incentive Plan and the conversion of all warrants and convertible securities into shares of common stock, or a total of 4,028,387 shares of common stock, will be available for awards under the Incentive Plan. In addition, (i) the maximum number of shares of common stock subject to awards granted during a single fiscal year to any non-employee director (as defined in the Incentive Plan), taken together with any cash fees paid to such non-employee director during the fiscal year, may not exceed $1.0 million and (ii) the maximum amount that can be paid to any participant for a single fiscal year during a performance period (or with respect to each single fiscal year if a performance period extends beyond a single fiscal year) pursuant to a performance compensation award denominated in cash may not exceed $10.0 million. No awards may be granted under the Incentive Plan on and after February 12, 2026. The Incentive Plan will continue to apply to awards granted prior to such date. During the three and six months ended June 30, 2024, 56,350 awards were granted to KREF's directors and employees of the Manager or its affiliates. As of June 30, 2024, 1,808,376 shares of common stock remained available for awards under the Incentive Plan.

KREF did not sell shares under the ATM and did not incur or pay any commissions to KCM during the three and six months ended June 30, 2024. In connection with the BMO Facility, and in consideration for its services as the structuring agent, KREF is obligated to pay KCM a structuring fee equal to 0.35% of the respective committed loan advances under the agreement. Such fees are capitalized as deferred financing cost and amortized to interest expense over the draw period of the facility.

The following table contains the Level 3 inputs used to value assets and liabilities on a recurring and nonrecurring basis or where KREF discloses fair value as of June 30, 2024: Fair Value Valuation Methodologies Unobservable Inputs (A) Weighted Average (B) Range Assets and Liabilities Commercial real estate loans, held-for-investment (C) $ 6,400,261 Discounted cash flow Discount margin 4.4% 3.1% - 17.2% Discount rate 10.0% 10.0% Capitalization rate 9.3% 9.3% $ 6,400,261 (A) An increase (decrease) in the valuation input results in a decrease (increase) in value. (B) Represents the average of the input value, weighted by the unpaid principal balance of the financial instrument. (C) Commercial real estate loans are generally valued using a discounted cash flow model using a discount rate derived from relevant market indices and/or estimates of the underlying property's value. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets not measured at fair value on an ongoing basis but subject to fair value adjustments only in certain circumstances, such as when there is evidence of impairment, are measured at fair value on a nonrecurring basis. KREF measures commercial real estate loans held-for-sale at the lower of cost or fair value and may be required, from time to time, to record a nonrecurring fair value adjustment. KREF measures commercial real estate loans held-for-investment at amortized cost, but may be required, from time to time, to record a nonrecurring fair value adjustment in the form of a CECL allowance. Assets and Liabilities for Which Fair Value is Only Disclosed KREF does not carry its secured financing agreements at fair value as management did not elect the fair value option for these liabilities. As of June 30, 2024 , the fair value of KREF's financing facilities approximated their respective carrying value.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes KREF has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code commencing with its taxable year ended December 31, 2014. A REIT is generally not subject to U.S. federal and state income tax on that portion of its income that is distributed to stockholders if it distributes at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gains. A REIT will also be subject to a nondeductible excise tax to the extent certain percentages of its taxable income are not distributed within specified dates. While KREF expects to distribute at least 90% of its net taxable income for the foreseeable future, KREF will continue to evaluate its capital and liquidity needs in light of existing economic and market conditions. KREF consolidates subsidiaries that incur U.S. federal, state and local income taxes, based on the tax jurisdiction in which each subsidiary operates. During the three and six months ended June 30, 2024, KREF recorded income tax expense of $0.1 million and $0.1 million, respectively, related to the operations of its taxable REIT subsidiaries and various other state and local taxes. During the three and six months ended June 30, 2023, KREF recorded income tax expense of $0.2 million and $0.3 million. There were no material deferred tax assets or liabilities as of June 30, 2024 and December 31, 2023.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The accompanying unaudited condensed consolidated financial statements and related notes of KREF are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and instructions to Form 10-Q. The condensed consolidated financial statements, including the accompanying notes, are unaudited and exclude some of the disclosures required in annual financial statements. The condensed consolidated financial statements include the accounts of KREF and its consolidated subsidiaries, and all intercompany transactions and balances have been eliminated. In the opinion of management, all adjustments considered necessary for a fair presentation of KREF’s financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These condensed consolidated financial statements should be read in conjunction with KREF's Annual Report on Form 10-K.
Use of Estimates	Use of Estimates — The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Management makes subjective estimates to project cash flows KREF expects to receive on its investments in loans and securities as well as the related market discount rates, which significantly impact the interest income, impairments, allowance for loan loss and fair values recorded or disclosed. Actual results could materially differ from those estimates.
Consolidation and Variable Interest Entities and Noncontrolling Interests	Consolidation — KREF consolidates those entities that (i) it controls through either majority ownership or voting rights or (ii) management determines that KREF is the primary beneficiary of entities deemed to be variable interest entities ("VIEs"). Variable Interest Entities — VIEs are entities (i) in which equity investors do not have an interest with the characteristics of a controlling financial interest, (ii) that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or (iii) established with non-substantive voting rights. A VIE is required to be consolidated only by its primary beneficiary, which is defined as the party that has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and that has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could be potentially significant to the VIE (Note 9). To assess whether KREF has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, KREF considers all the facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes, first, identifying the activities that most significantly impact the VIE’s economic performance; and second, identifying which party, if any, has power to direct those activities. To assess whether KREF has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE, KREF considers all of its economic interests and applies judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Collateralized Loan Obligations — KREF consolidates collateralized loan obligations (“CLOs”) when it determines that the CLO issuers are VIEs and that KREF is the primary beneficiary of such VIEs. The collateral assets of KREF's CLOs, comprised of a pool of loan participations, are included in “Commercial real estate loans, held-for-investment, net” on the Condensed Consolidated Balance Sheets. The liabilities of KREF's consolidated CLOs consist solely of obligations to the senior CLO noteholders, excluding subordinated CLO tranches held by KREF as such interests are eliminated in consolidation, and are presented in “Collateralized loan obligations, net” on the Condensed Consolidated Balance Sheets. The collateral assets of the CLOs can only be used to settle the obligations of the consolidated CLOs. The interest income from the CLOs’ collateral assets and the interest expense on the CLOs’ liabilities are presented on a gross basis in “Interest income” and “Interest expense”, respectively, in KREF's Condensed Consolidated Statements of Income. Real Estate Owned Joint Venture — KREF has two joint ventures that hold the majority of KREF’s investments in real estate owned (“REO”) and determined the joint ventures to be VIEs (Note 9). KREF owns a majority of the equity interests in the joint ventures and participates in the profits and losses. Management concluded that KREF is the primary beneficiary of the joint ventures as KREF holds decision-making power over the activities that most significantly impact the economic performance and has the obligation to absorb losses or the right to receive benefits that could be potentially significant to the joint ventures. Noncontrolling Interests — Noncontrolling interests represent the ownership interests in certain consolidated subsidiaries held by entities or persons other than KREF. These noncontrolling interests do not include redemption features and are presented as "Noncontrolling interests in equity of consolidated joint ventures" on the Condensed Consolidated Balance Sheets.
Equity Method Investments	Equity Method Investments — Investments are accounted for under the equity method when KREF has significant influence over the operations of an investee but does not consolidate that investment. Equity method investments, for which management has not elected a fair value option, are initially recorded at cost and subsequently adjusted for KREF's share of net income or loss and cash contributions and distributions each period. KREF classifies distributions received from equity method investees using the cumulative earnings approach. Distributions received up to the cumulative earnings from each equity method investee are considered returns on investment and presented within “Cash Flows from Operating Activities” in the Condensed Consolidated Statements of Cash Flows; excess distributions received are considered returns of investment and presented within “Cash Flows From Investing Activities” in the Condensed Consolidated Statements of Cash Flows.
Fair Value	Fair Value — GAAP requires the categorization of the fair value of financial instruments into three broad levels that form a hierarchy based on the transparency of inputs to the valuation. Level 1 — Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 — Inputs are other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar instruments in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 — Inputs are unobservable for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. KREF follows this hierarchy for its financial instruments. The classifications are based on the lowest level of input that is significant to the fair value measurement. Valuation Process — The Manager reviews the valuation of Level 3 financial instruments as part of KKR's quarterly process. As of June 30, 2024, KKR’s valuation process for Level 3 measurements, as described below, subjected valuations to the review and oversight of various committees. KKR has a global valuation committee assisted by the asset class-specific valuation committees, including a real estate valuation committee that reviews and approves all preliminary Level 3 valuations for real estate assets, including the financial instruments held by KREF. The global valuation committee is responsible for coordinating and implementing KKR’s valuation process to ensure consistency in the application of valuation principles across portfolio investments and between periods. All Level 3 valuations are also subject to approval by the global valuation committee. Valuation of Commercial Real Estate Loans — Management considers KREF's commercial real estate loans to be Level 3 assets in the fair value hierarchy as such assets are illiquid, structured investments that are specific to the sponsor, underlying property and its operating performance (Note 15). For financial statement disclosure purposes, on a quarterly basis, management generally engages an independent valuation firm to estimate the fair value of each loan categorized as a Level 3 asset. These loans are generally valued using a discounted cash flow model based on assumptions regarding the collection of principal and interest and estimated market rates. Management reviews the quarterly loan valuation estimates provided by the independent valuation firm. For collateral dependent loans, KREF may apply alternative valuation methods based on the fair value of the underlying collateral. Determination of collateral value involves significant judgment, including assumptions regarding capitalization rates, discount rates, leasing, occupancy rates, and other factors. Valuation of CLO Consolidated VIEs — Management estimates the fair value of the CLO liabilities using prices obtained from an independent valuation firm. If prices received from the independent valuation firm are inconsistent with values determined in connection with management’s independent review, management makes inquiries to the independent valuation firm about the prices received and related methods. In the event management determines the price obtained from an independent valuation firm to be unreliable or an inaccurate representation of the fair value of the CLO liabilities (based on considerations given to observable market data), management then compiles evidence independently and presents the independent valuation firm with such evidence supporting a different value. As a result, the independent valuation firm may revise their price after evaluating any additional evidence. However, if management continues to disagree with the price from the independent valuation firm, in light of evidence that management compiled independently and believes to be compelling, valuations are then prepared using inputs based on non-binding broker quotes obtained from independent, well-known, major financial brokers that are CLO market makers. In validating any non-binding broker quote used in this circumstance, management compares the non-binding quote to the observable market data points in addition to understanding the valuation methodologies used by the market makers. These market participants may utilize a similar methodology as the independent valuation firm to value the CLO liabilities, with the key input of expected yield determined independently based on both observable and unobservable factors. To avoid reliance on any single broker-dealer, management receives a minimum of two non-binding quotes, of which the average is used. Other Valuation Matters — For Level 3 financial assets originated, or otherwise acquired, and financial liabilities assumed during the current calendar quarter that were conducted in an orderly transaction with an unrelated party, management generally believes that the transaction price provides the most observable indication of fair value given the illiquid nature of these financial instruments, unless management is aware of any circumstances that may cause a material change in the fair value through the remainder of the reporting period. For instance, significant changes to the underlying property or its planned operations may cause material changes in the fair value of commercial real estate loans acquired, or originated, by KREF. KREF’s determination of fair value is based upon the best information available for a given circumstance and may incorporate assumptions that are management’s best estimates after consideration of a variety of internal and external factors. When an independent valuation firm expresses an opinion on the fair value of a financial instrument in the form of a range, management selects a value within the range provided by the independent valuation firm, generally the midpoint, to assess the reasonableness of management’s estimated fair value for that financial instrument.
Transfer of Financial Assets and Financing Agreements	Transfer of Financial Assets and Financing Agreements — KREF will, from time to time, transfer loans, securities and other assets as well as finance assets in the form of secured borrowings. In each case, management evaluates whether the transaction constitutes a sale through legal isolation of the transferred financial asset from KREF, the ability of the transferee to pledge or exchange the transferred asset without constraint and the transfer of control of the transferred asset. For transfers that constitute sales, KREF (i) recognizes the financial assets it retains and liabilities it has incurred, if any, (ii) derecognizes the financial assets it has sold, and derecognizes liabilities when extinguished and (iii) recognizes a realized gain, or loss, based upon the excess, or deficient, proceeds received over the carrying value of the transferred asset. KREF does not recognize a gain, or loss, on interests retained, if any, where management elected the fair value option prior to sale.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash — KREF considers cash equivalents as highly liquid short-term investments with maturities of 90 days or less when purchased. KREF maintains its cash deposits with major financial institutions. Substantially all such amounts on deposit exceed insured limits.
Commercial Real Estate Loans Held-For-Investment and Allowance for Credit Losses	Commercial Real Estate Loans Held-For-Investment and Allowance for Credit Losses — KREF recognizes its investments in commercial real estate loans based on management's intent, and KREF's ability, to hold those investments through their contractual maturity. Management classifies those loans that management does not intend to sell in the foreseeable future, and KREF is able to hold until maturity, as held-for-investment. Loans that are held-for-investment are carried at their aggregate outstanding principal, net of applicable (i) unamortized origination or acquisition premiums and discounts, (ii) unamortized deferred nonrefundable fees and other direct loan origination costs, and (iii) allowance for credit losses, net of write-offs of impaired loans . If a loan is determined to be impaired, management writes off the loan through a charge to the "Allowance for credit losses" and to the respective loan balance. Commencing in the second quarter of 2024, KREF estimated CECL reserves using the Weighted-Average Remaining Maturity, or the WARM method, which has been identified as a loss-rate method for estimating CECL reserves under GAAP. Under the WARM method, KREF references historical loan loss data across a comparable data set and applies such loss rate to each loan over its expected remaining term, taking into consideration expected economic conditions over the relevant timeframe. To arrive at a CECL reserve using the WARM method, KREF considers various factors including (i) historical loss experience in the commercial real estate lending market, (ii) timing of expected repayments and expected loan future funding, and (iii) KREF’s view of the current and future macroeconomic environment for a reasonable and supportable forecast period. KREF derives a historical loss rate predominately based on a commercial mortgage-backed securities (“CMBS”) database with historical losses from 1998 through 2024 provided by a third party. KREF focuses on the most relevant subset of CMBS data that is determined to be the most comparable to its own portfolio. The historical loss rate is further adjusted to consider expected macroeconomic conditions over reasonable and supportable forecast periods, such as considering commercial real estate price indices, unemployment rates and market liquidity. There is significant uncertainty related to future macroeconomic conditions. Therefore, KREF also considers other loan specific credit quality factors such as the risk rating of the loan, a near-term maturity, nature of construction loans, and economic conditions specific to the property type of the underlying collateral. For collateral dependent loans for which KREF determines foreclosure of the collateral is probable, KREF measures the expected losses based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. For collateral dependent loans for which KREF determines foreclosure is not probable, KREF applies a practical expedient to estimate expected losses using the difference between the collateral’s fair value (less costs to sell the asset if repayment is expected through the sale of the collateral) and the amortized cost basis of the loan. A loan is determined to be collateral dependent if (i) a borrower or sponsor is experiencing financial difficulty, and (ii) the loan is expected to be substantially repaid through the sale of the underlying collateral. Such determination requires the use of significant judgment and can be based on several factors subject to uncertainty. Considerations used in determination of financial difficulty may include, but are not limited to, whether the borrower's operating cash flow is sufficient to cover the current and future debt service requirements, the borrower’s ability to refinance the loan, market liquidity and other circumstances that can affect the borrower’s ability to satisfy its contractual obligations under the loan agreement.
Commercial Real Estate Loans Held-For-Sale	Commercial Real Estate Loans Held-For-Sale — Loans that KREF originates or acquires, which KREF is unable to hold, or management intends to sell or otherwise dispose of, in the foreseeable future are classified as held-for-sale and are carried at the lower of amortized cost or fair value. Commercial Real Estate Loans, Held-For-Sale — For commercial real estate loans held-for-sale, KREF applies the lower of cost or fair value accounting and may be required, from time to time, to record a nonrecurring fair value adjustment.
Real Estate Owned	Real Estate Owned — To maximize recovery from a defaulted loan, KREF may assume legal title or physical possession of the underlying collateral through foreclosure or the execution of a deed in lieu of foreclosure. Foreclosed properties are initially recognized at fair value in accordance with ASC 805 on KREF's Condensed Consolidated Balance Sheets as "Real Estate Owned" when KREF assumes either legal title or physical possession. KREF’s cost basis in REO equals the estimated fair value on the acquisition date. The value of acquired REO is allocated based on the relative fair values of assets acquired and liabilities assumed, including, but not limited to, land, building, furniture and fixtures, and intangibles. REO assets held for investment are evaluated for impairment on a quarterly basis. KREF considers the following factors when performing the impairment analysis: (i) significant underperformance relative to anticipated operating results; (ii) significant negative industry and economic outlook or trends; (iii) expected material costs necessary to extend the life or operate the REO asset; and (iv) KREF’s ability to hold and dispose of the REO asset in the ordinary course of business. A REO asset is considered for impairment when the sum of estimated future undiscounted cash flows to be generated by the REO asset over the estimated remaining holding period is less than the carrying value of such REO asset. An impairment charge is recorded when the carrying value of the REO exceeds the fair value. When determining the fair value of a REO asset, KREF makes certain assumptions including, but not limited to, projected operating cash flows, comparable selling prices and projected cash flows from the eventual disposition of the REO asset. REO assets are classified as held for sale in the period when they meet the criteria under ASC 360. Once a REO is classified as held for sale, depreciation is suspended and the asset is reported at the lower of its carrying value or fair value less cost to sell. The actual sales price of the REO could differ from the estimated fair value. If circumstances arise that were previously considered unlikely and, as a result, KREF decides not to sell the real estate asset previously classified as held for sale, the real estate asset is reclassified as held for investment. Upon reclassification, the real estate asset is measured at the lower of (i) its carrying amount prior to classification as held for sale, adjusted for depreciation expense that would have been recognized had the real estate been classified as held for investment, and (ii) its estimated fair value at the time of reclassification. For all REO assets (Note 4), KREF may opportunistically transact as suitable opportunities emerge.
Secured Financing Agreements and Secured Term Loan, Net	Secured Financing Agreements — KREF's secured financing agreements, including uncommitted repurchase facilities, term lending agreements, warehouse facility, asset specific financings and term loan facility, are treated as floating-rate collateralized financing arrangements carried at their contractual amounts, net of unamortized debt issuance costs (Note 5). Included within KREF's secured financing agreements is KREF's corporate revolving credit agreement ("Revolver"), which is full recourse to certain guarantor wholly-owned subsidiaries of KREF. Secured Term Loan, Net — KREF records its secured term loan at its contractual amount, net of unamortized original issuance discount and deferred financing costs (Note 7) on its Condensed Consolidated Balance Sheets. Any original issuance discount or deferred financing costs are amortized through the maturity date of the secured term loan as additional non-cash interest expense.
Dividends Payable	Dividends Payable — K REF records dividends payable on its common stock and preferred stock upon declaration of such d
Repurchased Stock	Repurchased Stock — KREF accounts for repurchases of its common stock based on the settlement date and presents repurchased stock in “Repurchased stock” on its Condensed Consolidated Balance Sheets (Note 10). Payments for stock
Income Recognition	Income Recognition Interest Income — KREF accrues interest income on loans based on the outstanding principal amount and contractual terms of the loan. Interest income also includes origination fees, direct loan origination costs and related exit fees for loans that KREF originates, but where management did not elect the fair value option, as a yield adjustment using the interest method over the loan term, or on a straight line basis when it approximates the interest method. KREF expenses origination fees and direct loan origination costs for loans acquired, but not originated, by KREF as well as loans for which management elected the fair value option, as incurred. Revenue from Real Estate Owned Operations — Revenue from REO operations is primarily comprised of rental income, including base rent and reimbursements of property operating expenses. For leases that have fixed and measurable base rent escalations, KREF recognizes base rent on a straight-line basis over the non-cancelable lease terms. The difference between such rental income earned and the cash rent amount is recorded as straight-line rent receivable and presented within "Other assets" on the Condensed Consolidated Balance Sheets. Reimbursement of property operating expenses arises from tenant leases which provide for the recovery of certain operating expenses and real estate taxes of the respective property. This revenue is accrued in the same periods as the expenses are incurred. Rental income is presented within “ Revenue from real estate owned operations ” in the Condensed Consolidated Statements of Income. Other Income — KREF recognizes interest income earned on its cash balances and miscellaneous fee income in “Other miscellaneous income” on its Condensed Consolidated Statements of Income. Gain (Loss) on Sale of Investments
Commercial Real Estate Loans, Held-For-Investment	Commercial Real Estate Loans, Held-For-Investment — For each loan in KREF's portfolio, management performs an evaluation, at least quarterly, of credit quality indicators of loans classified as held - for-investment using applicable loan, property, market and sponsor information obtained from borrowers, loan servicers and local market participants. Such indicators may include the net present value of the underlying collateral, property operating cash flows, the sponsor’s financial wherewithal and competency in managing the property, macroeconomic trends, and property submarket—specific economic factors. The evaluation of these credit quality indicators requires significant judgment by management to determine whether failure to collect contractual amounts is probable. If management deems that it is probable that KREF will be unable to collect all amounts owed according to the contractual terms of a loan, deterioration in credit quality of that loan is indicated. Management evaluates all available facts and circumstances that might impact KREF’s ability to collect outstanding loan balances when determining loan write-offs. These facts and circumstances may vary and may include, but are not limited to, (i) the underlying collateral performance and/or value, (ii) communications with the borrower, (iii) compliance with debt covenants, (iv) events of default by the borrower, or (v) other facts that impact the borrower’s ability to pay the contractual amounts due under the terms of the loan. If management considers a loan to be impaired, management writes off the loan through a charge to "Allowance for credit losses" based on the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral. Significant judgment is required in determining impairment and in estimating the resulting credit loss allowance, and actual losses, if any, could materially differ from those estimates. In certain circumstances, KREF may also modify terms of a loan agreement to accommodate a borrower experiencing financial difficulty. Such modifications typically include interest rate reductions, payment extension and modification of loan covenants. In conjunction with reviewing commercial real estate loans held-for-investment for impairment, KREF evaluates its commercial real estate loans at least once per quarter, assesses the risk factors of each loan, and assigns a risk rating based on a variety of factors, including, without limitation, underlying real estate performance, values of comparable properties, durability and quality of property cash flows, sponsor experience and financial wherewithal, and the existence of a risk-mitigating loan structure. Additional key considerations include debt service coverage ratios, loan structure, real estate and credit market dynamics, and risk of default or principal loss. Based on a five-point scale, KREF's loans are rated "1" through "5," from less risk to greater risk, which ratings are defined as follows: 1 (Very Low Risk); 2 (Low Risk); 3 (Medium Risk); 4 (High Risk/Potential for Loss); and 5 (Impaired/Loss Likely).
Accrued Interest Receivables	Accrued Interest Receivables — KREF elected not to measure an allowance for credit losses for accrued interest receivables. KREF generally writes off an accrued interest receivable balance when interest is 90 days or more past due unless the loan is both well secured and in the process of collection. Write-offs of accrued interest receivable are recognized as "Provision for (reversal of) credit losses, net" in the Condensed Consolidated Statements of Income.
Tenant Receivables	Tenant Receivables — KREF periodically reviews its REO tenant receivables for collectability, taking into consideration changes in factors such as the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area where the property is located. Tenant receivables, including receivables arising from the straight-lining of rents, are written-off directly when management deems that the collectability of substantially all future lease payments from a specified lease is not probable, at which point, KREF will begin recognizing revenue on a cash basis, based on actual amounts received (Note 4). Any receivables that are deemed to be uncollectible are recognized as a reduction to “ Revenue from real estate owned operations ” in the Condensed Consolidated Statements of Income .
Interest Expense	Interest Expense
Deferred Debt Issuance Costs	Deferred Debt Issuance Costs — KREF capitalizes and amortizes deferred financing costs incurred in connection with financing arrangements over their respective expected term using the interest method, or on a straight line basis when it approximates the interest method. KREF presents such expensed amounts, as well as deferred amounts written off, as additional interest expense in its Condensed Consolidated Statements of Income.
General and Administrative Expenses	General and Administrative Expenses — KREF expenses general and administrative costs, including legal and audit fees, insurance premiums, and other costs as incurred.
Management and Incentive Compensation to Affiliate	Management and Incentive Compensation to Affiliate
Income Taxes	Income Taxes — Certain activities of KREF are conducted through joint ventures that are formed as limited liability companies, taxed as partnerships, and consolidated by KREF. Some of these joint ventures are subject to state and local income taxes, based on the tax jurisdictions in which they operate. In addition, certain activities of KREF are conducted through taxable REIT subsidiaries consolidated by KREF. Taxable REIT subsidiaries are subject to federal, state and local income taxes (Note 16). As of June 30, 2024 and December 31, 2023, KREF did not have any material deferred tax assets or liabilities arising from future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in accordance with GAAP and their respective tax bases. KREF recognizes tax benefits for uncertain tax positions only if it is more likely than not that the position is sustainable based on its technical merits. Interest and penalties on uncertain tax positions are included as a component of the provision for income taxes in KREF's Condensed Consolidated Statements of Income. As of June 30, 2024, KREF did not have any material uncertain tax positions.
Stock-Based Compensation	Stock-Based Compensation
Earnings per Share	Earnings per Share KREF calculates basic earnings per share ("EPS") using the two-class method, which defines unvested share-based payment awards that contain nonforfeitable rights to dividends as participating securities. The two-class method is an allocation formula that determines earnings per share for each share of common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights. Basic EPS, is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common stock outstanding for the period.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Public entities with a single reportable segment are required to provide the new disclosures and all the disclosures required under ASC 280. The guidance is effective for KREF in its 2024 annual reporting. The guidance is applied retrospectively to all periods presented in the financial statements, unless it is impracticable. KREF is evaluating the impact of ASU 2023-07.
