[1] Total Segment Revenues is comprised of the following:

[2] Total Segment Expenses is comprised of the following:

[3] This adjustment removes Unrealized Performance Revenues on a segment basis.

[4] This adjustment removes Unrealized Principal Investment Income on a segment basis.

[5] This adjustment removes Interest and Dividend Revenue on a segment basis.

[6] This adjustment removes Other Revenue on a segment basis. For the years ended December 31, 2023, 2022 and 2021, Other Revenue on a GAAP basis was $(92.9) million, $184.6 million and $203.1 million and included $(94.7) million, $182.9 million and $200.6 million of foreign exchange gains (losses), respectively.

[7] This adjustment reverses the effect of consolidating Blackstone Funds, which are excluded from Blackstone’s segment presentation. This adjustment includes the elimination of Blackstone’s interest in these funds, the removal of revenue from the reimbursement of certain expenses by the Blackstone Funds, which are presented gross under GAAP but netted against Management and Advisory Fees, Net in the Total Segment measures, and the removal of amounts associated with the ownership of Blackstone consolidated operating partnerships held by non-controlling interests.

[8] This adjustment removes Transaction-Related and Non-Recurring Items, which are excluded from Blackstone’s segment presentation. Transaction-Related and Non-Recurring Items arise from corporate actions including acquisitions, divestitures, Blackstone’s initial public offering and non-recurring gains, losses, or other charges, if any. They consist primarily of equity-based compensation charges, gains and losses on contingent consideration arrangements, changes in the balance of the Tax Receivable Agreement resulting from a change in tax law or similar event, transaction costs, gains or losses associated with these corporate actions and non-recurring gains, losses or other charges that affect period-to-period comparability and are not reflective of Blackstone’s operational performance.

[9] This adjustment removes Unrealized Performance Allocations Compensation.

[10] This adjustment removes Equity-Based Compensation on a segment basis.

[11] This adjustment adds back Interest Expense on a segment basis, excluding interest expense related to the Tax Receivable Agreement.

[12] This adjustment removes the amortization of transaction-related intangibles, which are excluded from Blackstone’s segment presentation.

[13] This adjustment adds an amount equal to an administrative fee collected on a quarterly basis from certain holders of Blackstone Holdings Partnership Units. The administrative fee is accounted for as a capital contribution under GAAP, but is reflected as a reduction of Other Operating Expenses in Blackstone’s segment presentation.
