Fourth-Quarter Business Highlights:

•Revenues from Assets under management, administration, and distribution fees increased primarily from higher assets under management and administration due to increases from existing alternative investment clients of the Investment Managers segment due to new products and additional services. Market appreciation and positive cash flows into separately managed account programs and Strategist programs during 2023 also contributed to the increase in revenues.

•The increase in revenues from Assets under management, administration, and distribution fees was partially offset by negative cash flows from SEI fund programs in the Investment Advisors segment and client losses in the Institutional Investors segment.

•Average assets under management in equity and fixed income programs, excluding LSV, increased $5.0 billion, or 3%, to $167.4 billion during the fourth-quarter 2023, as compared to $162.4 billion during the fourth-quarter 2022 (see attached Average Asset Balances schedule for further details).

•Average assets under administration increased $133.5 billion, or 17%, to $923.4 billion during the fourth-quarter 2023, as compared to $789.9 billion during the fourth-quarter 2022 (see attached Average Asset Balances schedules for further details).

•Revenues from Information processing and software servicing fees increased from new client conversions and growth from existing SEI Wealth PlatformSM (SWP) clients.

•Net sales events in the Private Banks and Investment Managers segments during the fourth-quarter 2023 were $22.9 million and are expected to generate net annualized recurring revenues of approximately $17.6 million when contract values are completely realized. For the year ended 2023, net sales events were $97.5 million and are expected to generate net annualized recurring revenues of approximately $79.1 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 the fourth-quarter 2023 were negative $10.5 million. For the year ended 2023, net sales events were negative $18.9 million.

•Net sales events for newer initiatives, which includes SEI Sphere, were $1.3 million during the fourth-quarter 2023. For the year ended 2023, net sales events were $2.2 million.

•During the fourth-quarter 2023, we completed the acquisition of the National Pensions Trust and also acquired Altigo, a cloud-based technology platform that provides inventory, e-subscription, and reporting capabilities for alternative investments.

•The increase in operational expenses was due to higher personnel costs from business growth, competitive labor markets, and the impact of inflation on wages and services. Increased personnel costs and investments in compliance infrastructure to meet expanding regulatory requirements also contributed to the increase in operational expenses.

•One-time expense items during the fourth-quarter 2023 were approximately $11.0 million due to an asset write-off of previously capitalized software development costs of $5.3 million in the Investment Managers segment, $4.7 million in severance costs, and approximately $1.0 million in professional fees related to acquisition activity. Of the amount of severance costs during the fourth-quarter 2023, $4.0 million was recognized in Corporate overhead expenses.

•Earnings from LSV increased to $35.4 million in the fourth-quarter 2023 as compared to $31.7 million in the fourth-quarter 2022 due to market appreciation and increased performance fees. Net negative cash flows from existing clients and client losses partially offset the increase in earnings from LSV.

•Capitalized software development costs were $7.4 million in the fourth-quarter 2023, of which $4.5 million was for continued enhancements to SWP. Capitalized software development costs also include $2.9 million in the fourth-quarter 2023 for a new platform for the Investment Managers segment.

•Interest and dividend income increased to $11.6 million in the fourth-quarter 2023 as compared to $6.6 million in the fourth-quarter 2022, primarily due to higher interest rates.

•Effective tax rates were 19.6% in the fourth-quarter 2023 and 18.1% in the fourth-quarter 2022. The tax rate in the fourth-quarter 2023 was affected by reduced tax benefits related to stock option exercises.

•Repurchased shares of SEI common stock were 1.2 million for $68.9 million during the fourth-quarter 2023 at an average price of $58.08 per share.

•Cash flow from operations was $101.0 million, and free cash flow was $92.0 million during the fourth-quarter 2023.
