Net interest income increased 20% to $966 million thanks to higher average customer margin loans and customer credit balances and stronger securities lending activity.

Other fees and services increased 5% to $85 million, led by increases of $5 million in payments for order flow from exchange-mandated programs, $2 million in FDIC sweep fees and $2 million in market data fees, partially offset by a decrease of $9 million in risk exposure fees.

Execution, clearing and distribution fees decreased 21% to $91 million, driven by lower regulatory fees, as the SEC Section 31 transaction fee rate was reduced to zero on May 14, 2025, and greater capture of liquidity rebates from certain exchanges due to higher trading volumes in stocks and options.
