Non-interest expenses on a U.S. GAAP basis were $371.8 million for the three months ended September 30, 2025, compared to $304.0 million in the prior-year period. For the three months ended September 30, 2025, adjusted non-interest expenses were $359.0 million, compared with $287.1 million for the third quarter of 2024.

See "Explanation and Reconciliation of Non-GAAP Financial Measures" for a detailed explanation of the adjustments made to the corresponding U.S. GAAP measures and a reconciliation of U.S. GAAP to adjusted, non-GAAP financial information.

Compensation and Benefits

Compensation and benefits expenses, which are the largest component of our expenses, include salaries, incentive compensation, benefits, stock-based compensation, employment taxes, the reversal of expenses associated with the forfeiture of stock-based compensation and other employee-related costs. A significant portion of compensation expense is comprised of variable incentive arrangements, including discretionary incentive compensation, the amount of which fluctuates in proportion to the level of business activity, increasing with higher revenues and operating profits and decreasing with lower revenues and operating profits. Other compensation costs, primarily base salaries and benefits, are more fixed in nature. The timing of incentive compensation payments, which is generally in February, has a greater impact on our cash position and liquidity than is reflected on our consolidated statements of operations. In conjunction with our acquisitions, we have granted restricted stock, restricted cash with service conditions, and restricted mutual fund shares of investment funds ("MFRS Awards"), which are amortized to compensation expense over the service period. We have also entered into forgivable loans with service conditions, which are amortized to compensation expense over the loan term. Additionally, expense estimates related to revenue-based earnout arrangements with service conditions entered into as part of our acquisitions are amortized to compensation expense over the service period.

The following table summarizes our expected future acquisition-related compensation expense for restricted stock, restricted cash with service conditions, MFRS Awards and forgivable loans with service conditions, as well as expense estimates related to revenue-based earnout arrangements:

For the three months ended September 30, 2025, compensation and benefits expenses increased 25.1 percent to $288.9 million, compared with $231.0 million in the corresponding period of 2024, due to higher revenues. Compensation and benefits expenses as a percentage of net revenues decreased to 60.3 percent in the third quarter of 2025, compared to 64.2 percent in the third quarter of 2024, primarily due to higher net revenues including higher investment income on our investments and the noncontrolling interests in the alternative asset management funds that we manage. Our adjusted compensation ratio decreased to 61.7 percent in the third quarter of 2025, compared with 62.5 percent in the third quarter of 2024, primarily due to higher adjusted net revenues.

Outside Services

Outside services expenses include securities processing expenses, outsourced technology functions, outside legal fees, fund expenses associated with our consolidated alternative asset management funds and other professional fees. Outside services expenses increased slightly to $13.6 million in the third quarter of 2025, compared with $13.5 million in the corresponding period of 2024.

Occupancy and Equipment

For the three months ended September 30, 2025, occupancy and equipment expenses increased 18.0 percent to $19.4 million, compared with $16.5 million in the corresponding period of 2024, primarily due to incremental expenses as a result of relocating our Minneapolis corporate headquarters to a new building. We expect to incur additional occupancy costs related to this relocation in the fourth quarter of 2025.

Communications

Communication expenses include costs for telecommunication and data communication, primarily consisting of expenses for obtaining third-party market data information. For the three months ended September 30, 2025, communication expenses increased slightly to $13.8 million, compared with $13.7 million in the corresponding period of 2024.

Marketing and Business Development

Deal-Related Expenses

Deal-related expenses include costs we incurred over the course of a completed investment banking deal, which primarily consist of legal fees, offering expenses, and travel costs. For the three months ended September 30, 2025, deal-related expenses were $12.9 million, compared with $6.1 million for the three months ended September 30, 2024. The amount of deal-related expenses is principally dependent on the level and mix of deal activity and may vary from period to period as the recognition of deal-related costs typically coincides with the closing of a transaction.

Trade Execution and Clearance

For the three months ended September 30, 2025, trade execution and clearance expenses decreased modestly to $4.8 million, compared with $5.2 million in the corresponding period of 2024.
