ITEM 9A. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures The company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in the company’s reports under the Exchange Act is recorded, processed, and summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. An evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this annual report on Form 10-K was made under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer. Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (a) are effective to ensure that information required to be disclosed by us in reports filed 87 or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by SEC rules and forms and (b) include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Changes in Internal Control over Financial Reporting There have been no changes in our “internal control over financial reporting” (as defined in Rule 13a–15(f) of the Exchange Act) that occurred during the our most recent quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Management’s Report on Internal Control Over Financial Reporting Management of Blackstone Mortgage Trust, Inc. and subsidiaries, or Blackstone Mortgage Trust, is responsible for establishing and maintaining adequate internal control over financial reporting. Blackstone Mortgage Trust’s internal control over financial reporting is a process designed under the supervision of its Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of its consolidated financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). Blackstone Mortgage Trust’s internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets of the company; provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of the company’s management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on its financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Management conducted an assessment of the effectiveness of Blackstone Mortgage Trust’s internal control over financial reporting as of December 31, 2021, based on the framework established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on this assessment, management has determined that Blackstone Mortgage Trust’s internal control over financial reporting as of December 31, 2021, was effective. Deloitte & Touche LLP, an independent registered public accounting firm, has audited Blackstone Mortgage Trust’s financial statements included in this report on Form 10-K and issued its report on the effectiveness of Blackstone Mortgage Trust’s internal control over financial reporting as of December 31, 2021, which is included herein.

F-1 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Stockholders and the Board of Directors of Blackstone Mortgage Trust, Inc. New York, New York Opinions on the Financial Statements and Internal Control over Financial Reporting We have audited the accompanying consolidated balance sheets of Blackstone Mortgage Trust, Inc. and subsidiaries (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of operations, comprehensive income, changes in equity, and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and the schedule listed in the Index at Item 15(a) (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. Change in Accounting Principle As discussed in Note 2 to the financial statements, the Company has changed its method of accounting for credit losses in the year ended December 31, 2020 due to adoption of Accounting Standard Update, or ASU, 2016-13 “Financial Instruments – Credit Losses – Measurement of Credit Losses on Financial Instruments (Topic 326).” Basis for Opinions The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and F-2 that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matters The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Current Expected Credit Loss (“CECL”) Reserve – Adjustments to Reflect Management’s Estimation of Economic Conditions – Refer to Note 2 in the Financial Statements Critical Audit Matter Description The Company estimates its CECL reserve primarily using the Weighted Average Remaining Maturity (“WARM”) method, which has been identified as an acceptable loss-rate method for estimating CECL reserves. The Company utilizes its own historical loan loss data supplemented with the data obtained from an external service provider. The data obtained is subject to several screening and/or judgmental adjustments that are applied in order to better align this loan-level data to the attributes of the Company’s loan portfolio. The Company’s CECL reserve determined under the WARM method is further adjusted to reflect management’s estimation of the current and future economic conditions that may impact the performance of the commercial real estate assets securing the Company’s loans. The items considered in management’s estimation include unemployment rates, interest rates and other macroeconomic factors impacting the likelihood and magnitude of potential credit losses for the Company’s loans during their anticipated term. We identified the adjustments to the CECL reserve to reflect management’s estimation of the current and future economic conditions that may impact the performance of the commercial real estate assets securing the Company’s loans as a critical audit matter because of the subjectivity, complexity and estimation uncertainty in such adjustments made to account for the macroeconomic factors. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate whether the adjustments determined by management reasonably and appropriately quantify macroeconomic risks associated with the Company’s loan portfolio, including the need to involve our credit specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures to assess the adjustments applied by management to the CECL reserve to account for current and future economic conditions included, among others: • We tested the design and operating effectiveness of controls implemented by the Company in relation to the establishment of the CECL reserve. Specifically, in relation to the adjustments made to their CECL reserve to account for current and future economic conditions, we focused our procedures on internal controls related to evaluation of macroeconomic factors and other judgments involved in the determination of such adjustments. • We evaluated the appropriateness and consistency of the methods and assumptions used by management to develop the adjustments, assessed macro-economic and industry trends, and performed benchmarking analysis against peers. • We tested the accuracy and completeness of quantitative data used by management to develop the adjustments to account for current and future economic conditions. • We utilized credit specialists to assist in the evaluation of management’s CECL methodology and assumptions, including the estimation of economic conditions. F-3 CECL Reserve – Estimation of Fair Value of Underlying Collateral of Impaired Loans – Refer to Note 2 and Note 3 in the Financial Statements Critical Audit Matter Description The Company assesses the CECL reserve for impaired loans on an individual basis by comparing the estimated fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgment, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors deemed relevant by the Company. We identified the estimation of the fair value of the underlying collateral of impaired loans as a critical audit matter because of the complexity and judgement involved in the determination of the valuation methodology and assumptions, as well as subjectivity of the unobservable inputs utilized in the valuation. Auditing the fair value of the underlying collateral for impaired loans required a high degree of auditor judgment and increased effort, including the need to involve our fair value specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the estimate of fair of the underlying collateral of impaired loans as part of estimation of the CECL reserve included, among others: • We tested the design and operating effectiveness of controls over the estimation of the fair value of the collateral underlying the impaired loans, including specifically management’s review of the valuation model and underlying assumptions utilized in estimating the fair value of the underlying collateral. • We tested management’s assumptions through independent analysis and comparison to external sources. • We utilized our internal fair value specialists to assist in the evaluation of management’s valuation methodologies and assumptions. With the assistance of our specialists, we evaluated certain of these assumptions (e.g., guideline transactions, discount rates, capitalization rates). Our internal specialist procedures included testing the underlying source information of the assumptions, as well as developing a range of independent estimates and comparing those to the assumptions used by management. /s/ Deloitte & Touche LLP New York, New York February 9, 2022 We have served as the Company’s auditor since 2013 F-4 Blackstone Mortgage Trust, Inc.

Notes to Consolidated Financial Statements 1. ORGANIZATION References herein to “Blackstone Mortgage Trust,” “Company,” “we,” “us” or “our” refer to Blackstone Mortgage Trust, Inc. and its subsidiaries unless the context specifically requires otherwise. Blackstone Mortgage Trust is a real estate finance company that originates senior loans collateralized by commercial real estate in North America, Europe, and Australia. Our portfolio is composed primarily of loans secured by high-quality, institutional assets in major markets, sponsored by experienced, well-capitalized real estate investment owners and operators. These senior loans are capitalized by accessing a variety of financing options, including borrowing under our credit facilities, issuing CLOs or single-asset securitizations, and syndicating senior loan participations, depending on our view of the most prudent financing option available for each of our investments. We are not in the business of buying or trading securities, and the only securities we own are the retained interests from our securitization financing transactions, which we have not financed. We are externally managed by BXMT Advisors L.L.C., or our Manager, a subsidiary of Blackstone Inc., or Blackstone, and are a real estate investment trust, or REIT, traded on the New York Stock Exchange, or NYSE, under the symbol “BXMT.” Our principal executive offices are located at 345 Park Avenue, 24th Floor, New York, New York 10154. We were incorporated in Maryland in 1998, when we reorganized from a California common law business trust into a Maryland corporation. We conduct our operations as a REIT for U.S. federal income tax purposes. We generally will not be subject to U.S. federal income taxes on our taxable income to the extent that we annually distribute all of our net taxable income to stockholders and maintain our qualification as a REIT. We also operate our business in a manner that permits us to maintain an exclusion from registration under the Investment Company Act of 1940, as amended. We are organized as a holding company and conduct our business primarily through our various subsidiaries. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and include, on a consolidated basis, our accounts, the accounts of our wholly-owned subsidiaries, majority-owned subsidiaries, and variable interest entities, or VIEs, of which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made in the presentation of the prior period statements of changes in equity, statements of cash flows, and loans receivable in Note 3 to conform to the current period presentation. Principles of Consolidation We consolidate all entities that we control through either majority ownership or voting rights. In addition, we consolidate all VIEs of which we are considered the primary beneficiary. VIEs are defined as entities in which equity investors (i) do not have the characteristics of a controlling financial interest and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly affect the VIE’s economic performance and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE. In the third quarter of 2018, we contributed a loan to a single asset securitization vehicle, or the 2018 Single Asset Securitization, which is a VIE, and invested in the related subordinate position. We are not the primary beneficiary of the VIE because we do not have the power to direct the activities that most significantly affect the VIE’s economic performance and, therefore, do not consolidate the 2018 Single Asset Securitization on our balance sheet. We have classified the subordinate position we own as a held-to-maturity debt security that is included in other assets on our consolidated balance sheets. Refer to Note 17 for additional discussion of our VIEs. In April 2017, we entered into a joint venture, or our Multifamily Joint Venture, with Walker & Dunlop Inc. to originate, hold, and finance multifamily bridge loans. Pursuant to the terms of the agreements governing the joint venture, Walker & Dunlop contributed 15 % of the venture’s equity capital and we contributed 85 %. We consolidate the Multifamily Joint Venture as we have a controlling financial interest. The non-controlling interests included on our consolidated balance sheets represent the equity interests in our Multifamily Joint Venture that are owned by Walker & Dunlop. A portion of our F-11 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Multifamily Joint Venture’s consolidated equity and results of operations are allocated to these non-controlling interests based on Walker & Dunlop’s pro rata ownership of our Multifamily Joint Venture. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. As the novel coronavirus, or COVID-19, pandemic has evolved from its emergence in early 2020, so has its global impact. During the year ended December 31, 2021, many countries have re-instituted, or strongly encouraged, varying levels of quarantines and restrictions on travel and in some cases have at times limited operations of certain businesses and taken other restrictive measures designed to help slow the spread of COVID-19 and its variants. Governments and businesses have also instituted vaccine mandates and testing requirements for employees. While vaccine availability and uptake has increased, the longer-term macro-economic effects on global supply chains, inflation, labor shortages and wage increases continue to impact many industries, including the collateral underlying certain of our loans. Moreover, with the potential for new strains of COVID-19 to emerge, governments and businesses may re-impose aggressive measures to help slow its spread in the future. For this reason, among others, as the COVID-19 pandemic continues, the potential global impacts are uncertain and difficult to assess. We believe the estimates and assumptions underlying our consolidated financial statements are reasonable and supportable based on the information available as of December 31, 2021, however uncertainty over the ultimate impact COVID-19 will have on the global economy generally, and our business in particular, makes any estimates and assumptions as of December 31, 2021 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results may ultimately differ materially from those estimates. Revenue Recognition Interest income from our loans receivable portfolio and debt securities is recognized over the life of each investment using the effective interest method and is recorded on the accrual basis. Recognition of fees, premiums, and discounts associated with these investments is deferred and recorded over the term of the loan or debt security as an adjustment to yield. Income accrual is generally suspended for loans at the earlier of the date at which payments become 90 days past due or when, in the opinion of our Manager, recovery of income and principal becomes doubtful. Interest received is then recorded as a reduction in the outstanding principal balance until accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. In addition, for loans we originate, the related origination expenses are deferred and recognized as a component of interest income, however expenses related to loans we acquire are included in general and administrative expenses as incurred. Cash and Cash Equivalents Cash and cash equivalents represent cash held in banks and liquid investments with original maturities of three months or less. We may have bank balances in excess of federally insured amounts; however, we deposit our cash and cash equivalents with high credit-quality institutions to minimize credit risk exposure. We have not experienced, and do not expect, any losses on our cash or cash equivalents. As of both December 31, 2021 and December 31, 2020, we had no restricted cash on our consolidated balance sheets. Through our subsidiaries, we have oversight of certain servicing accounts held with third-party servicers, or Servicing Accounts, which relate to borrower escrows and other cash balances aggregating $ 531.2 million and $ 384.6 million as of December 31, 2021 and December 31, 2020, respectively. This cash is maintained in segregated bank accounts, and these amounts are not included in the assets and liabilities presented in our consolidated balance sheets. Cash in these Servicing Accounts will be transferred by the respective third-party servicer to the borrower or us under the terms of the applicable loan agreement upon occurrence of certain future events. We do not generate any revenue or incur any expenses as a result of these Servicing Accounts. Loans Receivable We originate and purchase commercial real estate debt and related instruments generally to be held as long-term investments at amortized cost. Debt Securities Held-to-Maturity We classify our debt securities as held-to-maturity, as we have the intent and ability to hold these securities until maturity. We include our debt securities in other assets on our consolidated balance sheets at amortized cost. F-12 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Current Expected Credit Losses Reserve The current expected credit loss, or CECL, reserve required under Accounting Standard Update, or ASU, 2016-13 “Financial Instruments – Credit Losses – Measurement of Credit Losses on Financial Instruments (Topic 326),” or ASU 2016-13, reflects our current estimate of potential credit losses related to our loans and debt securities included in our consolidated balance sheets. The initial CECL reserve recorded on January 1, 2020 is reflected as a direct charge to retained earnings on our consolidated statements of changes in equity; however subsequent changes to the CECL reserve are recognized through net income on our consolidated statements of operations. While ASU 2016-13 does not require any particular method for determining the CECL reserve, it does specify the reserve should be based on relevant information about past events, including historical loss experience, current portfolio and market conditions, and reasonable and supportable forecasts for the duration of each respective loan. In addition, other than a few narrow exceptions, ASU 2016-13 requires that all financial instruments subject to the CECL model have some amount of loss reserve to reflect the GAAP principal underlying the CECL model that all loans, debt securities, and similar assets have some inherent risk of loss, regardless of credit quality, subordinate capital, or other mitigating factors. We estimate our CECL reserve primarily using the Weighted Average Remaining Maturity, or WARM method, which has been identified as an acceptable loss-rate method for estimating CECL reserves in the Financial Accounting Standards Board Staff Q&A Topic 326, No. 1. The WARM method requires us to reference historic loan loss data across a comparable data set and apply such loss rate to each of our loans over their expected remaining term, taking into consideration expected economic conditions over the relevant timeframe. We apply the WARM method for the majority of our loan portfolio, which loans share similar risk characteristics. In certain instances, for loans with unique risk characteristics, we may instead use a probability-weighted model that considers the likelihood of default and expected loss given default for each such individual loan. Application of the WARM method to estimate a CECL reserve requires judgment, including (i) the appropriate historical loan loss reference data, (ii) the expected timing and amount of future loan fundings and repayments, and (iii) the current credit quality of our portfolio and our expectations of performance and market conditions over the relevant time period. To estimate the historic loan losses relevant to our portfolio, we have augmented our historical loan performance, with market loan loss data licensed from Trepp LLC. This database includes commercial mortgage-backed securities, or CMBS, issued since January 1, 1999 through November 30, 2021. Within this database, we focused our historical loss reference calculations on the most relevant subset of available CMBS data, which we determined based on loan metrics that are most comparable to our loan portfolio including asset type, geography, and origination loan-to-value, or LTV. We believe this CMBS data, which includes month-over-month loan and property performance, is the most relevant, available, and comparable dataset to our portfolio. Our loans typically include commitments to fund incremental proceeds to our borrowers over the life of the loan, which future funding commitments are also subject to the CECL model. The CECL reserve related to future loan fundings is recorded as a component of Other Liabilities on our consolidated balance sheets. This CECL reserve is estimated using the same process outlined above for our outstanding loan balances, and changes in this component of the CECL reserve will similarly impact our consolidated net income. For both the funded and unfunded portions of our loans, we consider our internal risk rating of each loan as the primary credit quality indicator underlying our assessment. The CECL reserve is measured on a collective basis wherever similar risk characteristics exist within a pool of similar assets. We have identified the following pools and measure the reserve for credit losses using the following methods: • U.S. Loans : WARM method that incorporates a subset of historical loss data, expected weighted-average remaining maturity of our loan pool, and an economic view. • Non-U.S. Loans : WARM method that incorporates a subset of historical loss data, expected weighted average remaining maturity of our loan pool, and an economic view. • Unique Loans : a probability of default and loss given default model, assessed on an individual basis. • Impaired Loans : impairment is indicated when it is deemed probable that we will not be able to collect all amounts due to us pursuant to the contractual terms of the loan. Determining that a loan is impaired requires significant judgment from management and is based on several factors including (i) the underlying collateral performance, (ii) discussions with the borrower, (iii) borrower events of default, and (iv) other facts that impact the borrower’s ability to pay the contractual amounts due under the terms of the loan. If a loan is determined to be impaired, we record the impairment as a component of our CECL reserve by applying the practical expedient for collateral dependent loans. The CECL reserve is assessed on an individual basis for these loans by comparing the estimated fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgments, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan F-13 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) sponsorship, actions of other lenders, and other factors deemed relevant by our Manager. Actual losses, if any, could ultimately differ materially from these estimates. We only expect to realize the impairment losses if and when such amounts are deemed nonrecoverable 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 non-recoverability may also be concluded if, in our determination, it is nearly certain that all amounts due will not be collected. We adopted ASU 2016-13 using the modified-retrospective method for all financial assets measured at amortized cost. Prior to our adoption, we had no loan loss provisions on our consolidated balance sheets. We recorded a cumulative-effective adjustment to the opening retained earnings in our consolidated statement of equity as of January 1, 2020. The following table details the impact of this adoption ($ in thousands): Impact of ASU 2016-13 Adoption Assets: Loans U.S. Loans $ 8,955 Non-U.S. Loans 3,631 Unique Loans 1,356 CECL reserve on loans $ 13,942 CECL reserve on held-to-maturity debt securities 445 Liabilities: CECL reserve on unfunded loan commitments 3,263 Total impact of ASU 2016-13 adoption on retained earnings $ 17,650 Contractual Term and Unfunded Loan Commitments Expected credit losses are estimated over the contractual term of each loan, adjusted for expected prepayments. As part of our quarterly review of our loan portfolio, we assess the expected repayment date of each loan, which is used to determine the contractual term for purposes of computing our CECL reserve. Additionally, the expected credit losses over the contractual period of our loans are subject to the obligation to extend credit through our unfunded loan commitments. The CECL reserve for unfunded loan commitments is adjusted quarterly, as we consider the expected timing of future funding obligations over the estimated life of the loan. The considerations in estimating our CECL reserve for unfunded loan commitments are similar to those used for the related outstanding loan receivables. Credit Quality Indicator Our risk rating is our primary credit quality indicator in assessing our current expected credit loss reserve. Our Manager performs a quarterly risk review of our portfolio of loans, and assigns each loan a risk rating based on a variety of factors, including, without limitation, LTV, debt yield, property type, geographic and local market dynamics, physical condition, cash flow volatility, leasing and tenant profile, loan structure and exit plan, and project sponsorship. Based on a 5-point scale, our loans are rated “l” through “5,” from less risk to greater risk, relative to our loan portfolio in the aggregate, which ratings are defined as follows: 1 - Very Low Risk 2 - Low Risk 3 - Medium Risk 4 - High Risk/Potential for Loss: A loan that has a risk of realizing a principal loss. 5 - Impaired/Loss Likely: A loan that has a very high risk of realizing a principal loss or has otherwise incurred a principal loss. F-14 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Estimation of Economic Conditions In addition to the WARM method computations and probability-weighted models described above, our CECL reserve is also adjusted to reflect our estimation of the current and future economic conditions that impact the performance of the commercial real estate assets securing our loans. These estimations include unemployment rates, interest rates, and other macroeconomic factors impacting the likelihood and magnitude of potential credit losses for our loans during their anticipated term. In addition to the CMBS data we have licensed from Trepp LLC, we have also licensed certain macroeconomic financial forecasts to inform our view of the potential future impact that broader economic conditions may have on our loan portfolio’s performance. These estimations require significant judgments about future events that, while based on the information available to us as of the balance sheet date, are ultimately indeterminate and the actual economic condition impacting our portfolio could vary significantly from the estimates we made as of December 31, 2021. Derivative Financial Instruments We classify all derivative financial instruments as either other assets or other liabilities on our consolidated balance sheets at fair value. On the date we enter into a derivative contract, we designate each contract as (i) a hedge of a net investment in a foreign operation, or net investment hedge, (ii) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability, or cash flow hedge, (iii) a hedge of a recognized asset or liability, or fair value hedge, or (iv) a derivative instrument not to be designated as a hedging derivative, or non-designated hedge. For all derivatives other than those designated as non-designated hedges, we formally document our hedge relationships and designation at the contract’s inception. This documentation includes the identification of the hedging instruments and the hedged items, its risk management objectives, strategy for undertaking the hedge transaction and our evaluation of the effectiveness of its hedged transaction. On a quarterly basis, we also formally assess whether the derivative we designated in each hedging relationship is expected to be, and has been, highly effective in offsetting changes in the value or cash flows of the hedged items. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued and the changes in fair value of the instrument are included in net income prospectively. Effective April 1, 2020, our net investment hedges are assessed using a method based on changes in spot exchange rates. Gains and losses, representing hedge components excluded from the assessment of effectiveness, are recognized in interest income on our consolidated statements of operations over the contractual term of our net investment hedges on a systematic and rational basis, as documented at hedge inception in accordance with our accounting policy election. All other changes in the fair value of our derivative instruments that qualify as hedges are reported as a component of accumulated other comprehensive income (loss) on our consolidated financial statements. Deferred gains and losses are reclassified out of accumulated other comprehensive income (loss) and into net income in the same period or periods during which the hedged transaction affects earnings, and are presented in the same line item as the earnings effect of the hedged item. For cash flow hedges, this is typically when the periodic swap settlements are made, while for net investment hedges, this occurs when the hedged item is sold or substantially liquidated. To the extent a derivative does not qualify for hedge accounting and is deemed a non-designated hedge, the changes in its fair value are included in net income concurrently. Secured Debt and Asset-Specific Debt We record investments financed with secured debt or asset-specific debt as separate assets and the related borrowings under any secured debt or asset-specific debt are recorded as separate liabilities on our consolidated balance sheets. Interest income earned on the investments and interest expense incurred on the secured debt or asset-specific debt are reported separately on our consolidated statements of operations. Senior Loan Participations In certain instances, we finance our loans through the non-recourse syndication of a senior loan interest to a third-party. Depending on the particular structure of the syndication, the senior loan interest may remain on our GAAP balance sheet or, in other cases, the sale will be recognized and the senior loan interest will no longer be included in our consolidated financial statements. When these sales are not recognized under GAAP we reflect the transaction by recording a loan participations sold liability on our consolidated balance sheet, however this gross presentation does not impact stockholders’ equity or net income. When the sales are recognized, our balance sheet only includes our remaining subordinate loan and not the non-consolidated senior interest we sold. F-15 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Term Loans We record our term loans as liabilities on our consolidated balance sheets. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the term loans as additional non-cash interest expense. Senior Secured Notes We record our senior secured notes as liabilities on our consolidated balance sheets. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the senior secured notes as additional non-cash interest expense. Convertible Notes The “Debt with Conversion and Other Options” Topic of the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, requires the liability and equity components of convertible debt instruments that may be settled in cash upon conversion, including partial cash settlement, to be separately accounted for in a manner that reflects the issuer’s nonconvertible debt borrowing rate. The initial proceeds from the sale of convertible notes are allocated between a liability component and an equity component in a manner that reflects interest expense at the rate of similar nonconvertible debt that could have been issued at such time. The equity component represents the excess initial proceeds received over the fair value of the liability component of the notes as of the date of issuance. We measured the estimated fair value of the debt component of our convertible notes as of the respective issuance dates based on our nonconvertible debt borrowing rate. The equity component of each series of our convertible notes is reflected within additional paid-in capital on our consolidated balance sheet, and the resulting issue discount is amortized over the period during which such convertible notes are expected to be outstanding (through the maturity date) as additional non-cash interest expense. The additional non-cash interest expense attributable to such convertible notes will increase in subsequent periods through the maturity date as the notes accrete to their par value over the same period. Deferred Financing Costs The deferred financing costs that are included as a reduction in the net book value of the related liability on our consolidated balance sheets include issuance and other costs related to our debt obligations. These costs are amortized as interest expense using the effective interest method over the life of the related obligations. Fair Value of Financial Instruments The “Fair Value Measurements and Disclosures” Topic o f the FASB, or ASC 820, defines fair value, establishes a framework for measuring fair value, and requires certain disclosures about fair value measurements under GAAP. Specifically, this guidance defines fair value based on exit price, or the price that would be received upon the sale of an asset or the transfer of a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a fair value hierarchy that prioritizes and ranks the level of market price observability used in measuring financial instruments. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument, and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination, as follows: • Level 1: Generally includes only unadjusted quoted prices that are available in active markets for identical financial instruments as of the reporting date. • Level 2: Pricing inputs include quoted prices in active markets for similar instruments, quoted prices in less active or inactive markets for identical or similar instruments where multiple price quotes can be obtained, and other observable inputs, such as interest rates, yield curves, credit risks, and default rates. • Level 3: Pricing inputs are unobservable for the financial instruments and include situations where there is little, if any, market activity for the financial instrument. These inputs require significant judgment or estimation by management of third-parties when determining fair value and generally represent anything that does not meet the criteria of Levels 1 and 2. F-16 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) The estimated value of each asset reported at fair value using Level 3 inputs is determined by an internal committee composed of members of senior management of our Manager, including our Chief Executive Officer, Chief Financial Officer, and other senior officers. Certain of our other assets are reported at fair value, as of quarter-end, either (i) on a recurring basis or (ii) on a nonrecurring basis, as a result of impairment or other events. Our assets that are recorded at fair value are discussed further in Note 16. We generally value our assets recorded at fair value by either (i) discounting expected cash flows based on assumptions regarding the collection of principal and interest and estimated market rates, or (ii) obtaining assessments from third-party dealers. For collateral-dependent loans that are identified as impaired, we measure impairment by comparing our Manager’s estimation of the fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgments, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors deemed relevant by our Manager. During the year ended December 31, 2020, we recorded an aggregate $ 69.7 million CECL reserve specifically related to two of our loans receivable. During the three months ended December 31, 2021, we charged off $ 14.4 million of the CECL reserve related to one of our loans receivable, bringing this asset-specific CECL reserve to $ 54.9 million as of December 31, 2021. The $ 54.9 million CECL reserve specifically related to one of our loans receivable with an outstanding principal balance of $ 286.3 million, net of cost-recovery proceeds, as of December 31, 2021. The CECL reserve was recorded based on our Manager’s estimation of the fair value of the loan’s underlying collateral as of December 31, 2021. This loan receivable is therefore measured at fair value on a nonrecurring basis using significant unobservable inputs, and is classified as a Level 3 asset in the fair value hierarchy. The significant unobservable inputs used to estimate the fair value of this loan receivable include the exit capitalization rate assumption of 4.80 % used to forecast the future sale price of the underlying real estate collateral and the unlevered discount rate of 8.30 %, in addition to reviewing comparable sales on a per-key basis. We are also required by GAAP to disclose fair value information about financial instruments, which are not otherwise reported at fair value in our consolidated balance sheet, to the extent it is practicable to estimate a fair value for those instruments. These disclosure requirements exclude certain financial instruments and all non-financial instruments. The following methods and assumptions are used to estimate the fair value of each class of financial instruments, for which it is practicable to estimate that value: • Cash and cash equivalents: The carrying amount of cash and cash equivalents approximates fair value. • Loans receivable, net: The fair values of these loans were estimated by our Manager based on a discounted cash flow methodology, taking into consideration various factors including capitalization rates, discount rates, leasing, credit worthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors deemed relevant by our Manager. • Debt securities held-to-maturity: The fair value of these instruments was estimated by utilizing third-party pricing service providers assuming the securities are not sold prior to maturity. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Derivative financial instruments: The fair value of our foreign currency and interest rate contracts was estimated using advice from a third-party derivative specialist, based on contractual cash flows and observable inputs comprising foreign currency rates and credit spreads. • Secured debt, net: The fair value of these instruments was estimated based on the rate at which a similar credit facility would currently be priced. • Securitized debt obligations, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Asset-specific debt, net: The fair value of these instruments was estimated based on the rate at which a similar agreement would currently be priced. F-17 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) • Term loans, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Senior secured notes, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Convertible notes, net: Each series of the convertible notes is actively traded and their fair values were obtained using quoted market prices. Income Taxes Our financial results generally do not reflect provisions for current or deferred income taxes on our REIT taxable income. We believe that we operate in a manner that will continue to allow us to be taxed as a REIT and, as a result, we generally do not expect to pay substantial corporate level taxes other than those payable by our taxable REIT subsidiaries. If we were to fail to meet these requirements, we may be subject to federal, state, and local income tax on current and past income, and penalties. Refer to Note 14 for additional information. Stock-Based Compensation Our stock-based compensation consists of awards issued to our Manager and certain individuals employed by an affiliate of our Manager that vest over the life of the awards, as well as deferred stock units issued to certain members of our board of directors. Stock-based compensation expense is recognized for these awards in net income on a variable basis over the applicable vesting period of the awards, based on the value of our class A common stock. Refer to Note 15 for additional information. Earnings per Share Basic earnings per share, or Basic EPS, is computed in accordance with the two-class method and is based on the net earnings allocable to our class A common stock, including restricted class A common stock and deferred stock units, divided by the weighted-average number of shares of our class A common stock, including restricted class A common stock and deferred stock units outstanding during the period. Our restricted class A common stock is considered a participating security, as defined by GAAP, and has been included in our Basic EPS under the two-class method as these restricted shares have the same rights as our other shares of class A common stock, including participating in any gains or losses. Diluted earnings per share, or Diluted EPS, is determined using the treasury stock method, and is based on the net earnings allocable to our class A common stock, including restricted class A common stock and deferred stock units, divided by the weighted-average number of shares of our class A common stock, including restricted class A common stock and deferred stock units. Refer to Note 11 for additional discussion of earnings per share. Foreign Currency In the normal course of business, we enter into transactions not denominated in United States, or U.S., dollars. Foreign exchange gains and losses arising on such transactions are recorded as a gain or loss in our consolidated statements of operations. In addition, we consolidate entities that have a non-U.S. dollar functional currency. Non-U.S. dollar denominated assets and liabilities are translated to U.S. dollars at the exchange rate prevailing at the reporting date and income, expenses, gains, and losses are translated at the average exchange rate over the applicable period. Cumulative translation adjustments arising from the translation of non-U.S. dollar denominated subsidiaries are recorded in other comprehensive income (loss). Underwriting Commissions and Offering Costs Underwriting commissions and offering costs incurred in connection with common stock offerings are reflected as a reduction of additional paid-in capital. Costs incurred that are not directly associated with the completion of a common stock offering are expensed when incurred. F-18 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” or ASU 2020-04. ASU 2020-04 provides optional expedients and exceptions to GAAP requirements for modifications on debt instruments, leases, derivatives, and other contracts, related to the expected market transition from LIBOR, and certain other floating rate benchmark indices, or collectively, IBORs, to alternative reference rates. ASU 2020-04 generally considers contract modifications related to reference rate reform to be an event that does not require contract remeasurement at the modification date nor a reassessment of a previous accounting determination. In January 2021, the FASB issued ASU 2021-01 “Reference Rate Reform (Topic 848): Scope,” or ASU 2021-01. ASU 2021-01 clarifies that the practical expedients in ASU 2020-04 apply to derivatives impacted by changes in the interest rate used for margining, discounting, or contract price alignment. The guidance in ASU 2020-04 is optional and may be elected over time, through December 31, 2022, as reference rate reform activities occur. Once ASU 2020-04 is elected, the guidance must be applied prospectively for all eligible contract modifications. In the first quarter of 2020, we have elected to apply the hedge accounting expedients, related to probability and the assessments of effectiveness, for future IBOR-indexed cash flows, to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with our past presentation. We continue to evaluate the impact of ASU 2020-04 and may apply other elections, as applicable, as the expected market transition from IBORs to alternative reference rates continues to develop. In August 2020, the FASB issued ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” or ASU 2020-06. ASU 2020-06 simplifies the accounting for convertible debt by eliminating the beneficial conversion and cash conversion accounting models. ASU 2020-06 also updates the earnings per share calculation and requires entities to assume share settlement when the convertible debt can be settled in cash or shares. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021 and is to be adopted through a cumulative-effect adjustment to the opening balance of retained earnings either at the date of adoption or in the first comparative period presented. Upon adoption of ASU 2020-06, convertible debt proceeds, unless issued with a substantial premium or an embedded conversion feature, will no longer be allocated between debt and equity components. This will reduce the issue discount and result in less non-cash interest expense in our consolidated financial statements. Additionally, ASU 2020-06 will result in the reporting of a diluted earnings per share, if the effect is dilutive, in our consolidated financial statements, regardless of our settlement intent. We expect to adopt ASU 2020-06 using the modified retrospective method of transition, which we expect will result in an aggregate decrease to our additional paid-in capital of $ 2.4 million, an aggregate decrease to our accumulated deficit of $ 2.0 million, and an aggregate increase to our convertible notes, net, balance of $ 476,000 , as of January 1, 2022. Reference Rate Reform LIBOR and certain other floating rate benchmark indices to which our floating rate loans and other loan agreements are tied, including, without limitation, the Euro Interbank Offered Rate, or EURIBOR, the Stockholm Interbank Offered Rate, or STIBOR, the Australian Bank Bill Swap Reference Rate, or BBSY, the Canadian Dollar Offered Rate, or CDOR, and the Swiss Average Rate Overnight, or SARON, or collectively, IBORs, are the subject of recent national, international and regulatory guidance and proposals for reform. As of December 31, 2021, the ICE Benchmark Association, or IBA, ceased publication of all non-USD LIBOR and previously announced its intention to cease publication of remaining U.S. dollar LIBOR settings immediately after June 30, 2023. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, has identified the Secured Overnight Financing Rate, or SOFR, a new index calculated using short-term repurchase agreements backed by Treasury securities, as its preferred alternative rate for USD LIBOR. Market participants have started to transition to the Sterling Overnight Index Average, or SONIA, in line with guidance from the U.K. regulators. As of December 31, 2021, one-month SOFR is utilized as the floating benchmark rate on 16 of our loans, the financing provided on the 2020 FL3 and 2020 FL2 CLOs, plus a credit spread adjustment of 0.11 %, and one of our credit facilities. As of December 31, 2021, the one-month SOFR was 0.05 % and one-month USD LIBOR was 0.10 %. Additionally, as of December 31, 2021, daily compounded SONIA is utilized as the floating benchmark rate on nine of our loans and five of our credit facilities. As of December 31, 2021, SONIA was 0.19 % and three-month GBP LIBOR was 0.26 %. At this time, it is not possible to predict how markets will respond to SOFR, SONIA, or other alternative reference rates as the transition away from USD LIBOR and GBP LIBOR proceeds. Despite the LIBOR transition in other markets, benchmark rate methodologies in Europe, Australia, Canada, and Switzerland have been reformed and rates such as EURIBOR, STIBOR, BBSY, CDOR, and SARON may persist as International Organization of Securities Commissions, or F-19 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) IOSCO, compliant reference rates moving forward. However, multi-rate environments may persist in these markets as regulators and working groups have suggested market participants adopt alternative reference rates. 3.

Total loan exposure encompasses the entire loan we originated and financed, including $ 1.5 billion and $ 801.8 million of such non-consolidated senior interests as of December 31, 2021 and December 31, 2020, respectively. (2) Excludes investment exposure to the 2018 Single Asset Securitization of $ 379.3 million and $ 735.5 million as of December 31, 2021 and December 31, 2020, respectively.

The weighted-average risk rating of our total loan exposure was 2.8 and 3.0 as of December 31, 2021 and 2020, respectively. The decrease in risk rating reflects the ongoing market recovery from COVID-19 and resulting improvement in the performance of the collateral assets underlying our portfolio, which resulted in several risk rating upgrades in our portfolio during the year ended December 31, 2021.

See Note 2 for further discussion of COVID-19. F-24 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) During 2020 and 2021, we entered into loan modifications related to a multifamily asset in New York City, which are classified as troubled debt restructurings under GAAP. During the three months ended June 30, 2020, we recorded a $ 14.8 million CECL reserve on this loan. During the three months ended December 31, 2021, the borrower committed significant additional capital to the property and engaged new management to oversee property operations, and we reduced the loan's outstanding principal balance to $ 37.5 million. As a result of the modification, we charged-off $ 14.4 million of the $ 14.8 million asset-specific CECL reserve we recorded on this loan during the three months ended June 30, 2020, and reversed the remaining $ 360,000 CECL reserve. We have no remaining asset-specific CECL reserve against this loan as of December 31, 2021. The loan is paying interest income current and we resumed income accrual for this loan as of December 31, 2021. See Note 2 to our consolidated financial statements for further discussion on the CECL reserve. During the third quarter of 2020, we entered into a loan modification related to a hospitality asset in New York City, which is classified as a troubled debt restructuring under GAAP.

As of July 1, 2020, the income accrual on this loan was suspended and no income was recorded subsequent to July 1, 2020. This loan has an outstanding principal balance of $ 286.3 million, net of cost-recovery proceeds, as of December 31, 2021. The CECL reserve was recorded based on our estimation of the fair value of the loan’s underlying collateral as of December 31, 2021. F-25 Blackstone Mortgage Trust, Inc.

DERIVATIVE FINANCIAL INSTRUMENTS The sole objective of our use of derivative financial instruments is to minimize the risks and/or costs associated with our investments and/or financing transactions. These derivatives may or may not qualify as net investment, cash flow, or fair value hedges under the hedge accounting requirements of ASC 815 – “Derivatives and Hedging.” Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements and other identified risks. Refer to Note 2 for additional discussion of the accounting for designated and non-designated hedges. The use of derivative financial instruments involves certain risks, including the risk that the counterparties to these contractual arrangements do not perform as agreed. To mitigate this risk, we only enter into derivative financial instruments with counterparties that have appropriate credit ratings and are major financial institutions with which we and our affiliates may also have other financial relationships. Cash Flow Hedges of Interest Rate Risk Certain of our transactions expose us to interest rate risks, which include a fixed versus floating rate mismatch between our assets and liabilities. We use derivative financial instruments, which includes interest rate caps, and may also include interest rate swaps, options, floors, and other interest rate derivative contracts, to hedge interest rate risk. The following tables detail our outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk (notional amount in thousands): December 31, 2021 Interest Rate Derivatives Number of Instruments Notional Amount Strike Index Wtd.-Avg.

During the twelve months following December 31, 2021, we estimate that an additional $ 4,000 will be reclassified from accumulated other comprehensive income (loss) as an increase to interest expense. Net Investment Hedges of Foreign Currency Risk Certain of our international investments expose us to fluctuations in foreign interest rates and currency exchange rates. These fluctuations may impact the value of our cash receipts and payments in terms of our functional currency, the U.S. dollar. We use foreign currency forward contracts to protect the value or fix the amount of certain investments or cash flows in terms of the U.S. dollar. F-36 Blackstone Mortgage Trust, Inc.

In addition to our class A common stock, we also issue deferred stock units to certain members of our board of directors in lieu of cash compensation for services rendered.

See Note 15 for further discussion of our stock-based incentive plans. Dividend Reinvestment and Direct Stock Purchase Plan On March 25, 2014, we adopted a dividend reinvestment and direct stock purchase plan, under which we registered and reserved for issuance, in the aggregate, 10,000,000 shares of class A common stock. Under the dividend reinvestment component of this plan, our class A common stockholders can designate all or a portion of their cash dividends to be reinvested in additional shares of class A common stock. The direct stock purchase component allows stockholders and new investors, subject to our approval, to purchase shares of class A common stock directly from us. During the years ended December 31, 2021, 2020, and 2019 we issued 2,184 shares, 2,050 shares, and 1,214 shares, respectively, of class A common stock under the dividend reinvestment component of the plan. As of December 31, 2021, a total of 9,989,790 shares of class A common stock remained available for issuance under the dividend reinvestment and direct stock purchase plan. At the Market Stock Offering Program On November 14, 2018, we entered into six equity distribution agreements, or ATM Agreements, pursuant to which we may sell, from time to time, up to an aggregate sales price of $ 500.0 million of our class A common stock. On July 26, 2019, we amended our existing ATM Agreements and entered into one additional ATM Agreement. Sales of class A common stock made pursuant to our ATM Agreements 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. Actual sales depend on a variety of factors including market conditions, the trading price of our class A common stock, our capital needs, and our determination of the appropriate sources of funding to meet such needs. During the year ended December 31, 2021, we issued and sold 296,901 shares of class A common stock under ATM Agreements, generating net proceeds totaling $ 9.9 million. During the year ended December 31, 2020, we did not issue any shares of our class A common stock under ATM Agreements. During the year ended December 31, 2019, we issued and sold 1,909,628 shares of class A common stock under ATM Agreements, generating net proceeds totaling $ 65.4 million. As of December 31, 2021, sales of our class A common stock with an aggregate sales price of $ 353.8 million remained available for issuance under our ATM Agreements. Dividends We generally intend to distribute substantially all of our taxable income, which does not necessarily equal net income as calculated in accordance with GAAP, to our stockholders each year to comply with the REIT provisions of the Internal Revenue Code. Our dividend policy remains subject to revision at the discretion of our board of directors. All distributions will be made at the discretion of our board of directors and will depend upon our taxable income, our financial condition, our maintenance of REIT status, applicable law, and other factors as our board of directors deems relevant. On December 15, 2021, we declared a dividend of $ 0.62 per share, or $ 104.3 million in aggregate, that was paid on January 14, 2022 to stockholders of record as of December 31, 2021. F-40 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) The following table details our dividend activity ($ in thousands, except per share data): Year Ended December 31, 2021 2020 2019 Dividends declared per share of common stock $ 2.48 $ 2.48 $ 2.48 Percent taxable as ordinary dividends 100.00 % 100.00 % 100.00 % Percent taxable as capital gain dividends — % — % — % 100.00 % 100.00 % 100.00 % Earnings Per Share We calculate our basic and diluted earnings per share using the two-class method for all periods presented as the unvested shares of our restricted class A common stock qualify as participating securities, as defined by GAAP. These restricted shares have the same rights as our other shares of class A common stock, including participating in any dividends, and therefore have been included in our basic and diluted net income per share calculation. Our Convertible Notes are excluded from dilutive earnings per share as we have the intent and ability to settle these instruments in cash. The following table sets forth the calculation of basic and diluted net income per share of class A common stock based on the weighted-average of both restricted and unrestricted class A common stock outstanding ($ in thousands, except per share data): Year Ended December 31, 2021 2020 2019 Net income (1) $ 419,193 $ 137,670 $ 305,567 Weighted-average shares outstanding, basic and diluted 151,521,941 141,795,977 130,085,398 Per share amount, basic and diluted $ 2.77 $ 0.97 $ 2.35 (1) Represents net income attributable to Blackstone Mortgage Trust. Other Balance Sheet Items Accumulated Other Comprehensive Income As of December 31, 2021, total accumulated other comprehensive income was $ 8.3 million, primarily representing $ 86.4 million of net realized and unrealized gains related to changes in the fair value of derivative instruments offset by $ 78.1 million of cumulative unrealized currency translation adjustments on assets and liabilities denominated in foreign currencies. As of December 31, 2020, total accumulated other comprehensive income was $ 11.2 million, primarily representing (i) $ 6.4 million of cumulative unrealized currency translation adjustments on assets and liabilities denominated in foreign currencies, and (ii) $ 4.8 million of net realized and unrealized gains related to changes in the fair value of derivative instruments. Non-Controlling Interests The non-controlling interests included on our consolidated balance sheets represent the equity interests in our Multifamily Joint Venture that are not owned by us. A portion of our Multifamily Joint Venture’s consolidated equity and results of operations are allocated to these non-controlling interests based on their pro rata ownership of our Multifamily Joint Venture. As of December 31, 2021, our Multifamily Joint Venture’s total equity was $ 203.5 million, of which $ 173.0 million was owned by us, and $ 30.5 million was allocated to non-controlling interests. As of December 31, 2020, our Multifamily Joint Venture’s total equity was $ 121.1 million, of which $ 102.9 million was owned by us, and $ 18.2 million was allocated to non-controlling interests. 13. OTHER EXPENSES Our other expenses consist of the management and incentive fees we pay to our Manager and our general and administrative expenses. F-41 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Management and Incentive Fees Pursuant to a management agreement between our Manager and us, or our Management Agreement, our Manager earns a base management fee in an amount equal to 1.50 % per annum multiplied by our outstanding equity balance, as defined in the Management Agreement. In addition, our Manager is entitled to an incentive fee in an amount equal to the product of (i) 20 % and (ii) the excess of (a) our Core Earnings (as defined in our Management Agreement) for the previous 12-month period over (b) an amount equal to 7.00 % per annum multiplied by our outstanding Equity, provided that our Core Earnings over the prior three-year period is greater than zero . Core Earnings, as defined in our Management Agreement, is generally equal to our 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), (iv) net income (loss) attributable to our legacy portfolio, (v) certain non-cash items, and (vi) incentive management fees. During the years ended December 31, 2021, 2020, and 2019, we incurred $ 64.2 million, $ 60.4 million, and $ 55.3 million, respectively, of management fees payable to our Manager. In addition, during the years ended December 31, 2021, 2020, and 2019, we incurred $ 24.3 million, $ 17.5 million, and $ 23.2 million, respectively, of incentive fees payable to our Manager. During the year ended December 31, 2020, we issued 840,696 shares of class A common stock to our Manager in satisfaction of our aggregate $ 19.3 million of management and incentive fees accrued in the first quarter of 2020. As of December 31, 2021 and 2020 we had accrued management and incentive fees payable to our Manager of $ 28.4 million and $ 19.2 million, respectively. General and Administrative Expenses General and administrative expenses consisted of the following ($ in thousands): Year Ended December 31, 2021 2020 2019 Professional services (1) $ 7,759 $ 7,324 $ 5,163 Operating and other costs (1) 3,762 4,015 3,035 Subtotal 11,521 11,339 8,198 Non-cash compensation expenses Restricted class A common stock earned 31,052 34,032 30,156 Director stock-based compensation 595 500 500 Subtotal 31,647 34,532 30,656 Total general and administrative expenses $ 43,168 $ 45,871 $ 38,854 (1) During the years ended December 31, 2021, 2020, and 2019, we recognized an aggregate $ 748,000 , $ 1.1 million, and $ 865,000 , respectively, of expenses related to our Multifamily Joint Venture. 14. INCOME TAXES We have elected to be taxed as a REIT under the Internal Revenue Code for U.S. federal income tax purposes. We generally must distribute annually at least 90% of our net taxable income, subject to certain adjustments and excluding any net capital gain, in order for U.S. federal income tax not to apply to our earnings that we distribute. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our net taxable income, we will be subject to U.S. federal income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to our stockholders in a calendar year is less than a minimum amount specified under U.S. federal tax laws. Our qualification as a REIT also depends on our ability to meet various other requirements imposed by the Internal Revenue Code, which relate to organizational structure, diversity of stock ownership, and certain restrictions with regard to the nature of our assets and the sources of our income. Even if we qualify as a REIT, we may be subject to certain U.S. federal income and excise taxes and state and local taxes on our income and assets. If we fail to maintain our qualification as a REIT for any taxable year, we may be subject to material penalties as well as federal, state, and local income tax on our taxable income at regular corporate rates and we would not be able to qualify as a REIT for the subsequent four full taxable years. As of December 31, 2021 and 2020, we were in compliance with all REIT requirements. F-42 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) Securitization transactions could result in the creation of taxable mortgage pools for federal income tax purposes. As a REIT, so long as we own 100% of the equity interests in a taxable mortgage pool, we generally would not be adversely affected by the characterization of the securitization as a taxable mortgage pool. Certain categories of stockholders, however, such as foreign stockholders eligible for treaty or other benefits, stockholders with net operating losses, and certain tax-exempt stockholders that are subject to unrelated business income tax, or UBTI, could be subject to increased taxes on a portion of their dividend income from us that is attributable to the taxable mortgage pool. We have not made UBTI distributions to our common stockholders and do not intend to make such UBTI distributions in the future. During the years ended December 31, 2021 and December 31, 2020, we recorded a current income tax provision of $ 423,000 and $ 323,000 , respectively, primarily related to activities of our taxable REIT subsidiaries and various state and local taxes. During the year ended December 31, 2019, we recorded a current income tax benefit of $ 506,000 , primarily due to a tax credit refund. We did not have any deferred tax assets or liabilities as of December 31, 2021 or 2020. We have net operating losses, or NOLs, generated by our predecessor business that may be carried forward and utilized in current or future periods. As a result of our issuance of 25,875,000 shares of class A common stock in May 2013, the availability of our NOLs is generally limited to $ 2.0 million per annum by change of control provisions promulgated by the Internal Revenue Service with respect to the ownership of Blackstone Mortgage Trust. As of December 31, 2021, we had estimated NOLs of $ 159.0 million that will expire in 2029, unless they are utilized by us prior to expiration. We have a full valuation allowance against such NOLs as it is probable that they will expire unutilized. As of December 31, 2021, tax years 2018 through 2021 remain subject to examination by taxing authorities. 15. STOCK-BASED INCENTIVE PLANS We are externally managed by our Manager and do not currently have any employees. However, as of December 31, 2021, our Manager, certain individuals employed by an affiliate of our Manager, and certain members of our board of directors were compensated, in part, through our issuance of stock-based instruments. We had stock-based incentive awards outstanding under nine benefit plans as of December 31, 2021. Seven of such benefit plans have expired and no new awards may be issued under them. Under our two current benefit plans, a maximum of 5,000,000 shares of our class A common stock may be issued to our Manager, our directors and officers, and certain employees of affiliates of our Manager. As of December 31, 2021, there were 1,170,042 shares available under our current benefit plans. The following table details the movement in our outstanding shares of restricted class A common stock and the weighted-average grant date fair value per share: Restricted Class A Common Stock Weighted-Average Grant Date Fair Value Per Share Balance as of December 31, 2019 1,698,582 $ 34.52 Granted 934,502 31.83 Vested ( 1,004,315 ) 34.26 Forfeited ( 879 ) 34.57 Balance as of December 31, 2020 1,627,890 $ 33.14 Granted 1,065,755 29.93 Vested ( 957,944 ) 33.08 Forfeited ( 29,580 ) 31.52 Balance as of December 31, 2021 1,706,121 $ 31.19 These shares generally vest in installments over a period of three years , pursuant to the terms of the respective award agreements and the terms of our current benefit plans. The 1,706,121 shares of restricted class A common stock outstanding as of December 31, 2021 will vest as follows: 893,701 shares will vest in 2022; 545,100 shares will vest in 2023; and 267,320 shares will vest in 2024. As of December 31, 2021, total unrecognized compensation cost relating to unvested share-based compensation arrangements was $ 51.3 million based on the grant date fair value of shares granted. This cost is expected to be recognized over a weighted-average period of 1.2 years from December 31, 2021. F-43 Blackstone Mortgage Trust, Inc.

Fair Value of Financial Instruments As discussed in Note 2, GAAP requires disclosure of fair value information about financial instruments, whether or not recognized at fair value in the statement of financial position, for which it is practicable to estimate that value. The following table details the book value, face amount, and fair value of the financial instruments described in Note 2 ($ in thousands): December 31, 2021 December 31, 2020 Book Value Face Amount Fair Value Book Value Face Amount Fair Value Financial assets Cash and cash equivalents $ 551,154 $ 551,154 $ 551,154 $ 289,970 $ 289,970 $ 289,970 Loans receivable, net 21,878,338 22,156,437 22,013,762 16,399,166 16,652,824 16,447,192 Debt securities held-to-maturity, net (1) 78,013 79,200 77,229 75,722 79,200 70,127 Financial liabilities Secured debt, net 12,280,042 12,299,580 12,299,580 7,880,536 7,896,863 7,896,863 Securitized debt obligations, net 2,838,062 2,855,625 2,850,399 2,922,499 2,940,638 2,923,489 Asset-specific debt, net 393,824 400,699 400,699 391,269 399,699 399,699 Secured term loans, net 1,327,406 1,349,271 1,335,844 1,041,704 1,062,766 1,053,060 Senior secured notes, net 394,010 400,000 399,012 — — — Convertible notes, net 619,876 622,500 630,821 616,389 622,500 621,568 (1) Included in other assets on our consolidated balance sheets. Estimates of fair value for cash and cash equivalents and convertible notes are measured using observable, quoted market prices, or Level 1 inputs. Estimates of fair value for debt securities held-to-maturity, securitized debt obligations, the term loans, and the senior secured notes are measured using observable, quoted market prices, in inactive markets, or Level 2 inputs. All other fair value significant estimates are measured using unobservable inputs, or Level 3 inputs. See Note 2 for further discussion regarding fair value measurement of certain of our assets and liabilities. 17. VARIABLE INTEREST ENTITIES Consolidated Variable Interest Entities We have financed a portion of our loans through the CLOs and the 2017 Single Asset Securitization, all of which are VIEs. During the year ended December 31, 2021, the 2017 Single Asset Securitization was liquidated upon full repayment of its collateral and all senior securities outstanding. We are the primary beneficiary of, and therefore consolidate, the CLOs on our balance sheet as we (i) control the relevant interests of the CLOs that give us power to direct the activities that most significantly affect the CLOs, and (ii) have the right to receive benefits and obligation to absorb losses of the CLOs through the subordinate interests we own. F-44 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) The following table details the assets and liabilities of our consolidated CLOs and 2017 Single Asset Securitization VIEs ($ in thousands): December 31, 2021 December 31, 2020 Assets: Loans receivable $ 3,486,750 $ 3,520,130 Current expected credit loss reserve ( 4,502 ) ( 13,454 ) Loans receivable, net 3,482,248 3,506,676 Other assets 20,746 81,274 Total assets $ 3,502,994 $ 3,587,950 Liabilities: Securitized debt obligations, net $ 2,838,062 $ 2,922,499 Other liabilities 1,800 2,104 Total liabilities $ 2,839,862 $ 2,924,603 Assets held by these VIEs are restricted and can be used only to settle obligations of the VIEs, including the subordinate interests owned by us. The liabilities of these VIEs are non-recourse to us and can only be satisfied from the assets of the VIEs. The consolidation of these VIEs results in an increase in our gross assets, liabilities, interest income and interest expense, however it does not affect our stockholders’ equity or net income. Non-Consolidated Variable Interest Entities In the third quarter of 2018, we contributed a $ 517.5 million loan to the $ 1.0 billion 2018 Single Asset Securitization, which is a VIE, and invested in the related $ 99.0 million subordinate position. We are not the primary beneficiary of the VIE because we do not have the power to direct the activities that most significantly affect the VIE’s economic performance and, therefore, do not consolidate the 2018 Single Asset Securitization on our balance sheet. We have classified the subordinate position we own as a held-to-maturity debt security that is included in other assets on our consolidated balance sheets. Our maximum exposure to loss from the 2018 Single Asset Securitization is limited to our book value of $ 78.0 million as of December 31, 2021. We are not obligated to provide, have not provided, and do not intend to provide financial support to these consolidated and non-consolidated VIEs. 18. TRANSACTIONS WITH RELATED PARTIES We are managed by our Manager pursuant to the Management Agreement, the current term of which expires on December 19, 2022, and will be automatically renewed for a one-year term upon such date and each anniversary thereafter unless earlier terminated. As of December 31, 2021 and 2020, our consolidated balance sheets included $ 28.4 million and $ 19.2 million of accrued management and incentive fees payable to our Manager, respectively. During the years ended December 31, 2021, 2020, and 2019, we paid aggregate management and incentive fees of $ 79.3 million, $ 78.9 million and $ 76.9 million, respectively, to our Manager. During the year ended December 31, 2020, we issued 840,696 shares of class A common stock to our Manager in satisfaction of our aggregate $ 19.3 million of management and incentive fees accrued in the first quarter of 2021. The per share price with respect to such issuance was calculated based on the volume-weighted average price on the NYSE of our class A common stock over the five trading days following our April 29, 2020 first quarter 2021 earnings conference call. In addition, during the years ended December 31, 2021, 2020, and 2019, we reimbursed our Manager for expenses incurred on our behalf of $ 601,000 , $ 1.0 million, and $ 1.1 million, respectively. As of December 31, 2021, our Manager held 1.1 million shares of unvested restricted class A common stock, which had an aggregate grant date fair value of $ 33.4 million, and vest in installments over three years from the date of issuance. During the years ended December 31, 2021, 2020, and 2019, we recorded non-cash expenses related to shares held by our Manager of $ 15.3 million, $ 17.0 million, and $ 15.1 million, respectively. Refer to Note 15 for further details on our restricted class A common stock. F-45 Blackstone Mortgage Trust, Inc. Notes to Consolidated Financial Statements (continued) An affiliate of our Manager is the special servicer of the CLOs. This affiliate did not earn any special servicing fees related to the CLOs during the years ended December 31, 2021, 2020 or 2019. During the years ended December 31, 2021, 2020, and 2019, we originated three loans, two loans, and nine loans respectively, whereby the respective borrowers engaged an affiliate of our Manager to act as title insurance agent in connection with these transactions. We did not incur any expenses or receive any revenues as a result of these transactions. During the years ended December 31, 2021, 2020, and 2019, we incurred $ 385,000 , $ 487,000 , and $ 440,000 , respectively, of expenses for various administrative, compliance, and capital markets data services to third-party service providers that are affiliates of our Manager. In the fourth quarter of 2021, we co-originated A$ 450.0 million of an aggregate A$ 900.0 million senior loan to an unaffiliated third-party. A Blackstone-advised investment vehicle co-originated the additional pari passu A$ 450.0 million of the loan. In the fourth quarter of 2021, we issued $ 400.0 million aggregate principal amount of 3.75 % Senior Secured Notes. The Senior Secured Notes were issued at par and have a maturity date of January 15, 2027. Blackstone Securities Partners L.P., an affiliate of our Manager, participated in the offering of the Senior Secured Notes and received compensation of $ 400,000 in connection therewith. This transaction was on terms equivalent to those of unaffiliated parties. In the third quarter of 2021, we originated $ 246.6 million of a total $ 503.0 million senior loan to an unaffiliated third-party, which was part of a total financing that included a mezzanine loan originated by a Blackstone-advised investment vehicle. We will forgo all non-economic rights under our loan, including voting rights, so long as any Blackstone-advised investment vehicle controls the mezzanine loan. The senior loan terms, with respect to the mezzanine lender, were negotiated by a third party without our involvement and our 49 % interest in the senior loan was made on such market terms. In the third quarter of 2021, we acquired £ 186.0 million of a total £ 379.6 million senior loan to a borrower that is majority owned by a Blackstone-advised investment vehicle.

COMMITMENTS AND CONTINGENCIES Impact of COVID-19 As further discussed in Note 2, the full extent of the impact of COVID-19 on the global economy generally, and our business in particular, is uncertain. As of December 31, 2021, no contingencies have been recorded on our consolidated balance sheet as a result of COVID-19, however as the global pandemic continues and the economic implications worsen, it may have long-term impacts on our financial condition, results of operations, and cash flows. Refer to Note 2 for further discussion of COVID-19. Unfunded Commitments Under Loans Receivable As of December 31, 2021, we had aggregate unfunded commitments of $ 4.2 billion across 118 loans receivable and $ 2.5 billion of committed or identified financing for those commitments resulting in net unfunded commitments of $ 1.7 billion. The unfunded loan commitments comprise funding for capital expenditures and construction, leasing costs, and interest and carry costs, and their fundability will vary depending on the progress of capital projects, leasing, and cash flows at the properties securing our loans. Therefore, the exact timing and amounts of such future loan fundings are uncertain and will depend on the current and future performance of the underlying collateral assets. We expect to fund our loan commitments over the remaining term of the related loans, which have a weighted-average future funding period of 3.6 years. F-47 Blackstone Mortgage Trust, Inc.
