Blackstone Announces Intra-Quarter Realization Update Relating to the Third Quarter

NEW YORK – September 24, 2024 – Blackstone today announced a preliminary estimate regarding revenue it expects to record related to realization activity for the period from July 1, 2024 to September 24, 2024. Based on information currently available, Blackstone preliminarily expects to record total Realized Performance Revenues and total Realized Principal Investment Income for this period in excess of $300 million. This estimate includes revenue related to investment realizations closed to date in the third quarter, as well as certain non-fee related incentive fees that are included in Realized Performance Revenues and other investment income expected to be realized at quarter end, and is comprised of approximately 85% Realized Performance Revenues and approximately 15% Realized Principal Investment Income.

The preliminary estimate regarding realization activity for the period from July 1, 2024 to September 24, 2024 disclosed above is not intended to predict or represent total Realized Performance Revenues, total Realized Principal Investment Income or total Segment Revenues for the quarter ending September 30, 2024, and results for the full quarter may differ materially. The preliminary estimate does not include the results or impact of any other sources of income, including fee income, or expenses, and Blackstone may realize further gains or losses relating to total Realized Performance Revenues and total Realized Principal Investment Income for the full quarter. This preliminary estimate is also not indicative of the results that may be expected for any other period, including the year ending December 31, 2024.
