Stifel Reports May 2023 Operating Data

ST. LOUIS, MO, June 22, 2023 – Stifel Financial Corp. (NYSE: SF) today reported selected operating results for May 31, 2023 in an effort to provide timely information to investors on certain key performance metrics. Due to the limited nature of this data, a consistent correlation to earnings should not be assumed.

Ronald J. Kruszewski, Chairman and Chief Executive Officer, said, “In May, total deposits increased while client cash balances were relatively flat with April’s levels. Through the first two months of the quarter, we experienced consistent growth in Smart Rate balances and have seen cash sorting continue to slow during June. Total client assets declined as solid recruiting was offset by declines in equity markets. Operating conditions for investment banking and our transactional businesses remain challenging. As such, we estimate that second quarter investment banking and transactional revenue will be down 10-15% and 5-10%, respectively, from the prior quarter.”
