Stifel Reports April 2026 Operating Data

ST. LOUIS, MO, May 28, 2026 – Stifel Financial Corp. (NYSE: SF) today reported selected operating results for April 30, 2026, 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, “Excluding the sale of Stifel Independent Advisors, LLC, total and fee-based client assets rose 19% and 25% year over year, respectively, driven by market appreciation and continued success in recruiting productive financial advisors. Treasury Deposits increased by 7% in April as

venture banking delivered strong growth, helping to partially offset seasonal declines in client money market and insured product balances. Loan growth also strengthened in April, increasing more than $1.2 billion as fund banking

activity rose significantly.”
