All values are in US Dollars.

First-Quarter Business Highlights:

•SEI achieved diluted EPS of $1.17, up 18% from the prior year, reflecting acceleration on the momentum achieved in the second half of 2024. SEI's strong EPS growth is attributable to both operating profit growth and margin improvement in each of our reportable segments, and the benefit of our share repurchase program. SEI had no material items in Q1 2025 affecting the comparability of EPS.

•Net sales events during the first quarter 2025 were $46.6 million, bringing net sales events for the trailing 12 months to $153.2 million. Both the single-quarter and trailing 12-month net sales events represent record-high levels for SEI, and similar to last quarter, the drivers of net sales activity were broad-based, coming from multiple existing and new clients.

◦Despite recent capital markets volatility, SEI's sales pipeline remains solid, and we have not yet sensed any slowdown in market activity.

•Consolidated revenues and operating income increased by 8% and 25%, respectively, from Q1 2024. SEI's consolidated operating margin of 28% represents the highest level achieved in the last three years, demonstrating increasing focus on profitability and cost leverage against healthy revenue growth.

◦Private Banks operating profit growth of 34% reflects the inflection in sales event momentum which began in Q2 2024, in addition to continued cost discipline.

◦Investment Managers operating profit growth of 19% was driven by sales event growth, particularly among alternative and global investment managers. Investment Managers also realized a benefit from new product offerings, notably our Luxembourg depositary services, reflecting investments to enhance our global service offering and operational footprint.

◦Investment Advisors operating profit growth of 15% was largely driven by a $20.8 million contribution from the Integrated Cash Program in Q1 2025, more than double the $9.6 million contribution realized in Q1 2024.

◦Relative to Q4 2024, both Investment Advisors and Institutional Investors realized modest revenue declines, mostly attributable to the full-quarter impact of AUM declines occurring in late 2024 and two fewer calendar days in Q1 2025 vs. Q4 2024.

•Average assets under administration increased by 3%, and average assets under management were flat relative to Q4 2024. Ending assets under management increased by 2% despite a 4.6% decline in US equities in Q1, reflecting SEI's significant diversification across asset types and geographies in addition to modest net inflows for the Advisors and Institutional segments.

◦Institutional Investor and Investment Advisor net flows were modestly positive as inflows into Strategist and traditional SMA offerings offset outflows in mutual fund products.

•Earnings from LSV decreased to $28.7 million in the first quarter 2025 as compared to $31.6 million in the first quarter 2024 due to the full-quarter impact of late-2024 AUM declines in addition to slightly lower incentive fees vs. Q1 2024.

•SEI repurchased 2.5 million shares of common stock for $192.8 million during the first quarter 2025 at an average price of $77.10 per share, bringing total shares repurchased to 8.5 million for the trailing 12 months.
