Blackstone |Blackstone Mortgage Trust, Inc. DEFINITIONS 14 Distributable Earnings: Blackstone Mortgage Trust, Inc. (“BXMT”) discloses Distributable Earnings in this presentation. Distributable Earnings is a financial measure that is calculated and presented on the basis of methodologies other than in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Distributable Earnings is a non-GAAP measure, which is defined as GAAP net income (loss), including realized gains and losses not otherwise recognized in current period GAAP net income (loss), and excluding (i) non-cash equity compensation expense, (ii) depreciation and amortization, (iii) unrealized gains (losses), and (iv) certain non-cash items. Distributable Earnings may also be adjusted from time to time to exclude one-time events pursuant to changes in GAAP and certain other non-cash charges as determined by BXMT’s manager, subject to approval by a majority of its independent directors. Distributable Earnings mirrors the terms of BXMT’s management agreement between BXMT’s Manager and BXMT, for purposes of calculating its incentive fee expense. BXMT’s CECL reserves have been excluded from Distributable Earnings consistent with other unrealized gains (losses) pursuant to its existing policy for reporting Distributable Earnings. BXMT expects to only recognize such potential credit losses in Distributable Earnings if and when such amounts are realized and deemed non-recoverable upon a realization event. This is generally at the time a loan is repaid, or in the case of foreclosure, when the underlying asset is sold, but realization and non-recoverability may also be concluded if, in BXMT’s determination, it is nearly certain that all amounts due will not be collected. The timing of any such credit loss realization in BXMT’s Distributable Earnings may differ materially from the timing of CECL reserves or charge-offs in BXMT’s consolidated financial statements prepared in accordance with GAAP. The realized loss amount reflected in Distributable Earnings will equal the difference between the cash received, or expected to be received, and the book value of the asset, and is reflective of its economic experience as it relates to the ultimate realization of the loan. BXMT believes that Distributable Earnings provides meaningful information to consider in addition to net income (loss) and cash flow from operating activities determined in accordance with GAAP. BXMT believes Distributable Earnings is a useful financial metric for existing and potential future holders of its class A common stock as historically, over time, Distributable Earnings has been a strong indicator of its dividends per share. As a REIT, BXMT generally must distribute annually at least 90% of its net taxable income, subject to certain adjustments, and therefore BXMT believes its dividends are one of the principal reasons stockholders may invest in BXMT’s class A common stock. Distributable Earnings helps BXMT to evaluate its performance excluding the effects of certain transactions and GAAP adjustments that BXMT believes are not necessarily indicative of BXMT’s current loan portfolio and operations and is a performance metric BXMT considers when declaring its dividends. Furthermore, BXMT believes it is useful to present Distributable Earnings prior to charge-offs of CECL reserves to reflect BXMT’s direct operating results and help existing and potential future holders of BXMT’s class A common stock assess the performance of BXMT’s business excluding such charge-offs. BXMT utilizes Distributable Earnings prior to charge-offs of CECL reserves as an additional performance metric to consider when declaring BXMT’s dividends. Distributable Earnings mirrors the terms of BXMT’s Management Agreement for purposes of calculating BXMT’s incentive fee expense. Therefore, Distributable Earnings prior to charge-offs of CECL reserves is calculated net of the incentive fee expense that would have been recognized if such charge-offs had not occurred. Distributable Earnings and Distributable Earnings prior to charge-offs of CECL reserves do not represent net income (loss) or cash generated from operating activities and should not be considered as alternatives to GAAP net income (loss), or indicators of BXMT’s GAAP cash flows from operations, measures of BXMT’s liquidity, or indicators of funds available for BXMT’s cash needs. In addition, BXMT’s methodology for calculating Distributable Earnings and Distributable Earnings prior to charge-offs of CECL reserves may differ from the methodologies employed by other companies to calculate the same or similar supplemental performance measures, and accordingly, BXMT’s reported Distributable Earnings and Distributable Earnings prior to charge-offs of CECL reserves may not be comparable to similar metrics reported by other companies. Adjusted Equity: BXMT discloses Adjusted Equity in this presentation. Adjusted Equity is a financial measure that is calculated and presented on the basis of methodologies other than in accordance with GAAP. Adjusted Equity reflects BXMT’s total equity, excluding the aggregate CECL reserve on loans receivable and unfunded commitments. BXMT believes that Adjusted Equity provides meaningful information to consider in addition to its total equity determined in accordance with GAAP in the context of assessing its debt-to-equity and total leverage ratios. The adjusted debt-to-equity and total leverage ratios are metrics used, in addition to unadjusted debt-to-equity and total leverage ratios, when evaluating BXMT’s capitalization structure, as Adjusted Equity excludes the unrealized impact of BXMT’s CECL reserve, which may vary from quarter-to-quarter as its loan portfolio changes and market and economic conditions evolve. BXMT believes these ratios, and therefore Adjusted Equity, are useful financial metrics for existing and potential future holders of its class A common stock to consider when evaluating how BXMT’s business is capitalized and the relative amount of leverage in its business. Adjusted Equity does not represent BXMT’s total equity and should not be considered as an alternate to GAAP total equity. In addition, BXMT’s methodology for calculating Adjusted Equity may differ from methodologies employed by other companies to calculate the same or similar supplemental measures, and accordingly, BXMT’s reported Adjusted Equity may not be comparable to the Adjusted Equity reported by other companies.

Blackstone |Blackstone Mortgage Trust, Inc. DEFINITIONS 15 Non-Consolidated Senior Interests: Senior interests in loans originated and syndicated to third parties. These non-recourse loan participations, which are excluded from the GAAP balance sheet, constitute additional financing capacity and are included in discussions of the loan portfolio. Net Loan Exposure: Represents loans that are included in BXMT’s consolidated financial statements, net of (i) asset specific debt, (ii) participations sold, (iii) cost-recovery proceeds, and (iv) CECL reserves on its loans receivable.

Blackstone |Blackstone Mortgage Trust, Inc. ENDNOTES 16 a. Based on Net Loan Exposure. See Appendix for definition. b. Dividend yield based on share price of $19.13 as of April 23, 2024. c. Reflects weighted average loan-to-value (“LTV”) as of the date investments were originated or acquired by BXMT excluding any loans that are impaired and any junior participations sold. d. Represents debt-to-equity ratio, which is the ratio of (i) total outstanding secured debt, asset-specific debt, term loans, senior secured notes, and convertible notes, in each case excluding unamortized deferred financing costs and discounts, less cash, to (ii) total equity. e. States and countries comprising less than 1% of total loan portfolio are excluded. f. Assets with multiple components are proportioned into relevant collateral types based on the allocated value of each collateral type. g. Represents repayments during the period on secured debt, asset-specific debt, securitizations, term loans, senior secured notes, and convertible notes, in each case net of borrowings under such financings during the period. h. Excludes 1.0% per annum of scheduled amortization payments under the Term Loan B. i. Date loan was originated or acquired by BXMT. Origination dates are subsequently updated to reflect material loan modifications. j. Certain loans include an aggregate $0.7B of Non-Consolidated Senior Interests which are not included in BXMT’s consolidated financial statements and exclude $100.5M of junior loan interests that BXMT has sold, but that remain included in BXMT’s consolidated financial statements as of March 31, 2024. Total loan includes unfunded commitments. k. The weighted-average cash coupon and all-in yield are expressed as a spread over the relevant floating benchmark rates. Excludes loans accounted for under the cost- recovery method. l. Maximum maturity assumes all extension options are exercised; however, floating rate loans generally may be repaid prior to their final maturity without penalty. m. Represents net loss attributable to Blackstone Mortgage Trust, Inc. n. Represents realized losses related to loan principal amounts deemed non-recoverable during the three months ended March 31, 2024. o. Represents realized gains (losses) on the repatriation of unhedged foreign currency. These amounts were not included in GAAP net loss, but rather as a component of other comprehensive income in our consolidated financial statements. p. Reflects the $6.3M incentive fee expense that would have been incurred if such charge-offs had not occurred. q. The weighted-average shares outstanding, basic, exclude shares issuable from a potential conversion of BXMT’s convertible notes. Consistent with the treatment of other unrealized adjustments to Distributable Earnings, these potentially issuable shares are excluded until a conversion occurs.
