On February 11, 2026, Blackstone Mortgage Trust, Inc. (the "Company") announced that the Company's Board of Directors (the "Board") has appointed Marcin Urbaszek, the Company's current Deputy Chief Financial Officer, to serve as the Company's Chief Financial Officer, Treasurer and Assistant Secretary, effective as of the close of business on February 11, 2026. The Board approved the appointment on February 8, 2026.

Mr. Urbaszek has served as the Company's Deputy Chief Financial Officer since January 2, 2025. Before joining Blackstone in 2024, he had served as the Vice President, Chief Financial Officer, Treasurer and Head of Investor Relations of Granite Point Mortgage Trust since its inception in 2017. Mr. Urbaszek has over 20 years of corporate finance and strategic advisory experience, across roles in investment banking, capital markets and equity research, with over 15 years dedicated to financial institutions. Mr. Urbaszek received a B.B.A. in Finance from Zicklin School of Business, Bernard M. Baruch College, CUNY and is a CFA<sup>®</sup> charterholder.

Mr. Urbaszek's appointment coincides with the resignation, also effective as of the close of business on February 11, 2026, of Anthony F. Marone, Jr. as the Company's Chief Financial Officer, Treasurer and Assistant Secretary. Mr. Marone is resigning in recognition of Mr. Urbaszek's experience and strong qualifications for the position and in order to focus on his duties as Global Head of Blackstone Real Estate Finance. Mr. Marone's decision to resign was not the result of any disagreement with the Company on any matter relating to the Company's operations, policies or practices. Mr. Marone delivered his resignation on February 6, 2026.

The selection of Mr. Urbaszek to serve as Chief Financial Officer, Treasurer and Assistant Secretary of the Company was not pursuant to any arrangement or understanding with any other person. There are no family relationships between Mr. Urbaszek and any director or executive officer of the Company, and there are no transactions between Mr. Urbaszek and the Company that would be required to be reported under Item 404(a) of Regulation S-K.
