Forward Looking Statements and Other Matters This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which reflect Blackstone Mortgage Trust, Inc. s ( BXMT ) current views with respect to, among other things, BXMT s operations and financial performance, including performance of its recently acquired loan portfolio from GE Capital. You can identify these forward-looking statements by the use of words such as outlook, indicator, believes, expects, potential, continues, may, will, should, seeks, approximately, predicts, intends, plans, estimates, anticipates or the negative version of these words or other comparable words. Additionally, other statements in this presentation reflecttheopinionofbxmt smanagementasofthedatesindicated.such forward-looking statements are subject to various risks and uncertainties. Accordingly, there are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in these statements. BXMT believes these factors include but are not limited to those described under the section entitled Risk Factors in its Annual Report on Form 10-K for the fiscal year ended December 31, 2014 and under the section entitled Risks Related to the Loan Portfolio Acquisition in its Current Report on Form 10-Q for the fiscal quarter ended March 31, 2015, as such factors may be updated from time to time in its periodic filings with the SEC which are accessible on the SEC s website at www.sec.gov. These factors should not be construed as exhaustive and should be read in conjunction with the other cautionary statements that are included in this presentation and in the filings. BXMT assumes no obligation to update or supplement forward looking statements that become untrue because of subsequent events or circumstances. We refer to Core Earnings, which is a non-gaap financial measure, in this presentation. A reconciliation of core earnings to net income, the most directly comparable GAAP measure, is included in this presentation and in our most recent Annual Report on Form 10-K, and is available on our website at www.bxmt.com. Slide 17 of this presentation includes a reference to imputed core return on equity ( Imputed Core ROE ) and other economic terms relating to an illustrative BXMT loan transaction that are presented solely for purposes of illustrating the impact of using floating rate financing to finance the origination of a floating rate loan and should not be viewed as indicative of the results that will be achieved for any particular loan in BXMT s portfolio or of BXMT s results as a whole. The loan economics presented are hypothetical and based upon a number of assumptions, including no defaults on the loan, and are subject to various risks and uncertainties. Accordingly, there are or will be important factors, including those referred to above, that could cause the actual economics that are achieved on any loan in BXMT s loan portfolio to differ materially from those indicated in this illustration. In particular, it should be noted that as a result of such factors the net spread between whole loan yields and the cost of related leverage, the leverage multiple applicable to any particular loan and allocable overhead may vary materially from period to period and across BXMT s loan portfolio. Imputed Core ROE also excludes potential incentive management fees and is presented before any tax effects. Information included in this presentation is as of or for the period ended September 30, 2015, unless otherwise indicated. 1
