Supplemental Information	12. Supplemental Information Stock-Based Awards Stock-based compensation recognized for awards authorized under the Company’s employee stock incentive plans during the three and six months ended June 30, 2026 was $22.0 million and $34.5 million, respectively, and for the three and six months ended June 30, 2025 was $11.7 million and $23.4 million, respectively. This was included as a component of stock-based compensation in Office and general expenses and Cost of services within the Unaudited Consolidated Statements of Operations. Certain of the Company’s subsidiaries grant awards to their employees providing them with an equity interest in the respective subsidiary (the “profits interests awards”). The profits interests awards generally provide the employee with the right, but not the obligation, to sell their profits interest in the subsidiary to the Company based on a performance-based formula and, in certain cases, receive a profit share distribution. The profits interests awards are primarily settled in cash, with certain awards having stock-settlement provisions at the Company’s discretion. The corresponding liability associated with these profits interests awards was $7.3 million and $12.8 million as of June 30, 2026 and December 31, 2025, respectively, and was included as a component of Accruals and other liabilities and Other Liabilities on the Unaudited Consolidated Balance Sheets. For the three and six months ended June 30, 2026, the change in the fair value of these awards resulted in a decrease in stock-based compensation expense of $3.5 million and $1.7 million, respectively. For the three and six months ended June 30, 2025, the change in the fair value of these awards resulted in an increase in stock-based compensation expense of $8.3 million and $8.0 million, respectively. This was included as a component of stock-based compensation in Cost of services within the Unaudited Consolidated Statements of Operations. Transfer of Accounts Receivable The Company transfers certain of its trade receivable assets to third parties under certain agreements. Per the terms of these agreements, the Company surrenders control over its trade receivables upon transfer. The trade receivables transferred to the third parties were $165.9 million, and $335.0 million for the three and six months ended June 30, 2026, respectively, and were $114.3 million and $243.5 million for the three and six months ended June 30, 2025, respectively. The amount collected and due to the third parties under these arrangements was $28.9 million, and $21.2 million as of June 30, 2026 and December 31, 2025, respectively, and was included as a component of Accruals and other liabilities on the Unaudited Consolidated Balance Sheets. Fees for these arrangements were recorded in Office and general expenses in the Unaudited Consolidated Statements of Operations and totaled $1.8 million, and $3.6 million for the three and six months ended June 30, 2026, respectively, and totaled $1.3 million, and $2.8 million for the three and six months ended June 30, 2025, respectively. Related Party Transactions In the ordinary course of business, the Company enters into transactions with related parties, including its affiliates.
