Item 7.01. Regulation FD Disclosure.

On July 1, 2025, SEI Investments Company (the "Company") and Aquiline Capital Partners LP ("Aquiline"), a private investment firm specializing in financial services and technology, announced the close of Aquiline's acquisition of the Company's Family Office Services business effective June 30, 2025. The definitive agreement for the sale to Aquiline was previously disclosed on February 27, 2025.

A copy of the Company's press release related to the announcement is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The information furnished pursuant to Item 7.01 and Exhibit 99.1 hereof shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing with the Securities and Exchange Commission, except as shall be expressly provided by specific reference in such filing. The information furnished pursuant to Item 7.01 and Exhibit 99.1 hereof is not intended to, and does not, constitute a determination or admission by the Company that such information is material or complete, or that investors should consider this information before making an investment decision with respect to any security of the Company.

This Current Report on Form 8-K and press release filed as Exhibit 99.1 contain forward-looking statements within the meaning or the rules and regulations of the United States Securities and Exchange Commission. In some cases, you can identify forward-looking statements by terminology, such as “may,” “will,” “expect,” “believe” and “continue” or “appear.” SEI’s forward-looking statements include its’s current expectations as to the degree to which Aquiline will continue to enhance the Archway Platform, drive industry adoption, and enable Archway’s clients’ success.

You should not place undue reliance on the forward-looking statements, as they are based on the current beliefs and expectations of SEI’s management and subject to significant risks and uncertainties, many of which are beyond the control of SEI’s management and are subject to change. Although SEI’s management believes the assumptions upon which it bases SEI’s forward-looking statements are reasonable, they could be inaccurate.

Some of the additional risks and important factors that could cause actual results to differ from those described in SEI’s forward-looking statements can be found in the “Risk Factors” section of SEI’s Annual Report on Form 10-K for the year ended Dec. 31, 2024, filed with the United States Securities and Exchange Commission.
