•

Execution, clearing and distribution fees increased 1% to $116 million, driven by a new FINRA Consolidated Audit Trail ("CAT") fee initiated during the fourth quarter of 2024 and higher customer trading volumes in stocks, options and futures, mostly offset by greater capture of liquidity rebates from certain exchanges.

•	General and administrative expenses increased 17% to $61 million, driven primarily by an increase of $8 million in advertising expenses.

•	Pretax profit margin for the current quarter was 75% both as reported and as adjusted. For the year-ago quarter, pretax margin was 72% as reported and 73% as adjusted.
