On February 4, 2022, the Board of Trustees of Blackstone Secured Lending Fund appointed David Goldberg to the position of interim Chief Accounting Officer and interim Treasurer of the Fund, effective as of the close of business on March 11, 2022. Mr. Goldberg is a Managing Director with Blackstone Inc. (“Blackstone”) in the Global Fund Finance group where he oversees the accounting, financial reporting and fund administration for Blackstone's credit, liquid and insurance funds. Before joining Blackstone in 2008, Mr. Goldberg was an AVP at Lehman Brothers in the Real Estate Private Equity Group overseeing two real estate mezzanine funds.

Mr. Goldberg's appointment coincides with the resignation, effective as of the close of business on March 11, 2022, of Robert Busch as the Chief Accounting Officer and Treasurer of the Fund. Mr. Busch's decision to resign was based on a desire to pursue other opportunities and not the result of any disagreement relating to Blackstone or the Fund's operations, policies or practices.
