(1) This prospectus supplement relates to $300,930,496 unsold aggregate offering price of shares of class A common stock (the “Unsold Shares”) that were previously covered by the registrant’s then-active registration statement on Form S-3, filed with the Securities and Exchange Commission on July 26, 2019 (File No. 333-232852) (the “Prior Registration Statement”), pursuant to a prospectus supplement thereunder filed on July 26, 2019 (the “Prior Prospectus Supplement”). The prospectus supplement filed hereby supersedes and replaces the Prior Prospectus Supplement.

(2) Calculated in accordance with Rule 457(o) under the Securities Act of 1933 (as amended, the “Securities Act”).

(3) Payment of the registration fee in connection with the Unsold Shares was made at the time of filing of the Prior Prospectus Supplement. In accordance with Rule 415(a)(6) under the Securities Act of 1933, as amended, the Unsold Shares were previously registered on the Prior Registration Statement. In connection with the prior registration of the Unsold Shares, Blackstone Mortgage Trust, Inc. paid a registration fee of $60,600, which will continue to be applied to such unsold securities. Pursuant to Rule 457(p) under the Securities Act, a registration fee credit of $36,472.78 is available to offset the current registration fee. This “Calculation of Registration Fee” table shall be deemed to update the “Calculation of Registration Fee” table in the current registration statement on Form S-3 filed with the Securities and Exchange Commission on July 29, 2022 (File No. 333-266403).
