Blackstone Secured Lending Fund Declares Special Distribution

New York, NY – Blackstone Secured Lending Fund (the “Fund”) today announced that the Board of Trustees declared a special distribution of $0.30 per common share to shareholders of record as of December 14, 2020. The special distribution is payable on January 29, 2021. The special distribution is in addition to the Fund’s regular quarterly distributions for the quarter. Including the special distribution, the Fund’s distribution yield in 2020 was 9.2%, which is calculated as 2020 fiscal year declared distributions per share divided by $25.05, the most recent net asset value per share approved by the Board of Trustees as of December 14, 2020.

This special distribution is payable in 2021 but will be treated as having been paid by the Fund and received by shareholders as of December 31, 2020. The Fund anticipates this special distribution will be paid from ordinary income.
