First-Quarter Business Highlights:

•Revenues from Asset management, administration, and distribution fees increased from higher assets under management and administration due to market appreciation during 2021 and positive cash flows from new and existing clients. The decline in market conditions during the first quarter 2022 negatively impacted our revenues from assets under management and administration and partially offset our revenue growth.

•A significant, uninstalled investment processing client terminated an agreement for convenience. As a result, we recorded one-time fees of $88.0 million during first-quarter 2022. This early termination fee is included in Information processing and software servicing fees of the Private Banks segment and reflects a diluted earnings per share impact of $0.47 net of associated costs.

•Our average assets under administration increased $71.8 billion, or 9%, to $893.4 billion in the first-quarter 2022, as compared to $821.6 billion during the first-quarter 2021 (see attached Average Asset Balances schedules for further details).

•Our average assets under management, excluding LSV, increased $13.2 billion, or 5%, to $293.6 billion in the first-quarter 2022, as compared to $280.4 billion during the first-quarter 2021 (see attached Average Asset Balances schedules for further details).

•Net sales events, excluding the cancelled contract item, in the Private Banks and Investment Managers segments during first-quarter 2022 were $26.6 million and are expected to generate net annualized recurring revenues of approximately $24.7 million when contract values are completely realized.

•Net sales events in asset management-related businesses of the Investment Advisors and Institutional Investors segments and the Asset Management Distribution (AMD) business in the Private Banks segment during first-quarter 2022 were $2.1 million.

•Revenues from our acquisition of SEI Novus were $3.1 million during the first-quarter 2022. SEI Novus was acquired during the fourth-quarter 2021 and is reported in the Institutional Investors segment. The Institutional Investors segment also includes personnel, amortization, and other costs related to SEI Novus.

•The increase in operational expenses was primarily due to increased direct costs related to increased revenues, as well as increased personnel costs due to business growth and competitive labor markets.

•Earnings from LSV decreased to $32.5 million in the first-quarter 2022 as compared to $33.4 million in the first-quarter 2021 due to negative cash flows from existing clients and client losses, which offset the positive impact from market appreciation during 2021.

•We capitalized $6.6 million of software development costs in first-quarter 2022 for continued enhancements to the SEI Wealth PlatformSM (SWP). Amortization expense related to SWP was $13.6 million in first-quarter 2022.

•Our effective tax rates were 23.1% in first-quarter 2022 and 22.6% in first-quarter 2021. The increase in the effective tax rate was primarily due to decreased tax benefits associated with a lower volume of stock option exercises.

•We repurchased 1.7 million shares of our common stock for $100.1 million during the first-quarter 2022 at an average price of $58.43 per share.

•Cash flow from operations was $260.4 million, or $1.86 per share, and free cash flow was $244.6 million during the first-quarter 2022.
