Basis of Presentation

The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America. Certain financial information and accompanying note disclosure normally included in the Company’s Annual Report on Form 10-K have been condensed or omitted. The interim financial information is unaudited but reflects all adjustments (consisting of only normal recurring adjustments) which are, in the opinion of management, necessary for a fair statement of financial position of the Company as of March 31, 2026, the results of operations for the three months ended March 31, 2026 and 2025, and cash flows for the three months ended March 31, 2026 and 2025. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

There have been no significant changes in significant accounting policies during the three months ended March 31, 2026 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2025.

Variable Interest Entities

The Company or its affiliates have created numerous investment products for its clients in various types of legal entity structures. For entities determined to be a variable interest entity (VIE) in which the Company has a variable interest, an evaluation is required to determine whether the Company is the primary beneficiary. The Company evaluates its economic interests in the entity specifically determining if the Company has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. When making the determination on whether the benefits received from an entity are significant, the Company considers the total economics of the entity, and analyzes whether the Company’s share of the economics is significant. The Company utilizes qualitative factors, and, where applicable, quantitative factors, while performing the analysis. At each balance sheet date, the Company determines whether any reconsideration events, such as capital contributions and redemptions, either by the Company or third parties, have occurred that require it to revisit the VIE analysis and will consolidate or deconsolidate accordingly

Consolidated Variable Interest Entities

VIEs which the Company controls as the primary beneficiary have been included in the Company’s Consolidated Financial Statements. The results of the consolidated VIEs are reported on a one-month lag due to the timing of the receipt of related financial statements. To the extent the Company is aware of material events that affect the consolidated VIEs during the intervening period, the impact of the events would be disclosed in the Notes to Consolidated Financial Statements.

The Company's consolidated net income on the accompanying Consolidated Statement of Operations includes the income (loss) attributable to non-controlling interests. The portion of the consolidated VIEs owned by other investors is included in Redeemable Non-controlling Interests on the accompanying Consolidated Balance Sheet. Activity related to other investors of the consolidated VIEs is eliminated through Net income attributable to non-controlling interests on the accompanying Consolidated Statement of Operations.

Investments held by consolidated VIEs are recorded at fair value. Unrealized gains and losses from the investments are recognized in Net gain from consolidated variable interest entities on the accompanying Consolidated Statement of Operations.

The Company deconsolidates all the assets and liabilities of the non-controlling interests from the Consolidated Balance Sheets once it no longer qualifies as the primary beneficiary of a consolidated VIE. See Note 15 for related disclosures regarding the Company's consolidated VIEs.

Redeemable Non-controlling Interests

Non-controlling interests that are redeemable outside the Company's control at fixed or determinable prices and dates are presented as temporary equity in the accompanying Consolidated Balance Sheets. Redeemable non-controlling interests are recorded at the greater of the redemption fair value or the carrying value of the non-controlling interest and adjusted each reporting period for income, loss and any distributions made. Remeasurements to the redemption value of the redeemable non-controlling interest are recognized in capital in excess of par value. As of December 31, 2025 and March 31, 2026, the Company has a redeemable non-controlling interest related to an acquisition (See Note 12).

The Company also includes redeemable non-controlling interests related to consolidated VIEs as temporary equity on the accompanying Consolidated Balance Sheets. Non-controlling interests in consolidated VIEs are subject to redemption by future investors. When redeemable amounts become legally payable to the investors, they are classified as a liability and included in Liabilities of consolidated variable interest entities on the Consolidated Balance Sheets.

Changes in the Company's redeemable non-controlling interests are as follows:

Non-consolidated Variable Interest Entities

The Company serves as the Manager, Administrator and Distributor for certain investment products and may also serve as the Trustee for some of the investment products. The Company receives asset management, distribution, administration and custodial fees for these services. Clients are the equity investors and participate in proportion to their ownership percentage in the net income or loss and net capital gains or losses of the products, and, on liquidation, will participate in proportion to their ownership percentage in the remaining net assets of the products after satisfaction of outstanding liabilities. The Company has concluded that it is not the primary beneficiary of the entities in which it serves as the Manager, Administrator, Distributor or Trustee and, therefore, is not required to consolidate any of the pooled investment vehicles for which it receives asset management, distribution, administration and custodial fees under the VIE model.

The Company is a party to expense limitation agreements with certain SEI-sponsored money market funds subject to Rule 2a-7 of the Investment Company Act of 1940 which establish a maximum level of ordinary operating expenses incurred by the fund in any fiscal year including, but not limited to, fees of the administrator or its affiliates. Under the terms of these agreements, the Company waived $5,077 and $4,133 in fees during the three months ended March 31, 2026 and 2025, respectively.

Revenue Recognition

Revenue is recognized when the transfer of control of promised goods or services under the terms of a contract with customers are satisfied in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those promised goods or services. Certain portions of the Company’s revenues involve a third party in providing goods or services to its customers. In such circumstances, the Company must determine whether the nature of its promise to the customer is to provide the underlying goods or services (the Company is the principal in the transaction and reports the transaction gross) or to arrange for a third party to provide the underlying goods or services (the entity is the agent in the transaction and reports the transaction net). See Note 14 for related disclosures regarding revenue recognition.

Cash and Cash Equivalents

The Company considers investment instruments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents includes $73,254 and $201,675 at March 31, 2026 and December 31, 2025, respectively, invested in SEI-sponsored open-ended money market investment products. See Note 5 for information related to the Company's total investments in SEI-sponsored and non-SEI-sponsored money market investment products and commercial paper classified as cash equivalents.

Capitalized Software

The Company capitalized $5,546 and $7,362 of software development costs during the three months ended March 31, 2026 and 2025, respectively, to further develop the SEI Wealth Platform SM(SWP) and for the development of a new platform for the Investment Managers segment. The Company capitalized $3,972 and $4,375 of software development costs for significant enhancements to SWP during the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026, the net book value of SWP was $190,654, which includes $3,972 of capitalized software development costs in-progress associated with future releases. SWP has a weighted average remaining life of 7.4 years. Amortization expense for SWP was $7,564 and $7,099 during the three months ended March 31, 2026 and 2025, respectively.

The Company also capitalized $1,574 and $2,987 of software development costs during the three months ended March 31, 2026 and 2025, respectively, related to the development of a new platform for the Investment Managers segment. The Company placed the platform into service during the third quarter 2025. The net book value of the platform at March 31, 2026 was $40,092, which includes $1,574 of capitalized software development costs in-progress associated with future releases. As of March 31, 2026, the platform has a weighted average useful life of 6.4 years. Amortization expense for the platform was $1,508 during the three months ended March 31, 2026.

Earnings per Share

The calculations of basic and diluted earnings per share for the three months ended March 31, 2026 and 2025 are:

During the three months ended March 31, 2026 and 2025, employee stock options to purchase 4,426,000 and 5,834,000 shares of common stock with an average exercise price of $75.27 and $65.95, respectively, were outstanding but not included in the computation of diluted earnings per common share. These options for the three month periods were not included in the computation of diluted earnings per common share because either the performance conditions have not been satisfied or would not have been satisfied if the reporting date was the end of the contingency period or the options' exercise price was greater than the average market price of the Company’s common stock and the effect on diluted earnings per common share would have been anti-dilutive.

New Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03) and in January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (ASU 2025-01), which clarified the effective date of ASU 2024-03. This standard requires new disclosures to disaggregate prescribed natural expenses underlying any income statement caption. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 on a prospective basis and interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of adopting the guidance on its consolidated financial statements and related disclosures.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (ASU 2025-03). This standard eliminates the presumption that the primary beneficiary of a VIE is the accounting acquirer in a business combination. Instead, entities are required to apply the general guidance in ASC 805 to determine the accounting acquirer when the transaction is primarily effected by the exchange of equity interests. ASU 2025-03 is effective for annual and interim periods beginning after December 15, 2026 on a prospective basis. Early adoption is permitted. The Company is currently evaluating the impact of adopting the guidance on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal Use Software (ASU 2025-06). This standard clarifies capitalization thresholds for software development costs and aligns accounting treatment more closely with the economic substance of modern software development activities. ASU 2025-06 is effective for annual and interim periods beginning after December 15, 2027 on a retrospective, prospective or modified prospective basis. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2025-06 on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (ASU 2025-11). ASU 2025-11 is intended to improve the clarity and navigability of interim reporting guidance by (i) specifying the required form and content of interim financial statements, (ii) consolidating and organizing interim disclosure requirements across the Codification, and (iii) introducing a disclosure principle requiring entities to describe events occurring after the end of the most recent annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for public business entities for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting ASU 2025-11 on its consolidated financial statements and related disclosures.

Reclassifications

Certain prior year amounts have been reclassified to conform to current year presentation.

Note 2 –Equity Method Investments

The Company's equity method investments included in Investments on the accompanying Consolidated Balance Sheets consist of:

LSV Asset Management

The Company has an investment in LSV Asset Management (LSV), a registered investment advisor that provides investment advisory services primarily to institutions, including pension plans and investment companies. LSV is currently an investment sub-advisor for a limited number of SEI-sponsored investment products. The Company's partnership interest in LSV as of March 31, 2026 was 38.5%. The Company’s interest in the net assets of LSV is included in Investments on the accompanying Consolidated Balance Sheets and its interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliate on the accompanying Consolidated Statements of Operations.

The Company accounts for its interest in LSV using the equity method because of its less than 50% ownership. The Company’s interest in the earnings of LSV is reflected in Equity in earnings of unconsolidated affiliates on the accompanying Consolidated Statements of Operations.

At March 31, 2026 and December 31, 2025, the Company’s total investment in LSV was $54,879 and $121,512, respectively. The Company's investment includes advances provided to LSV related to their working capital accounts. The Company receives partnership distributions from LSV on a quarterly basis. The Company received partnership distributions from LSV of $33,886 and $34,860 in the three months ended March 31, 2026 and 2025, respectively. As such, the Company considers these distribution payments as returns on investment rather than returns of the Company's original investment in LSV and has therefore classified the associated cash inflows as an operating activity on the Consolidated Statements of Cash Flows.

The Company’s proportionate share in the earnings of LSV was $32,092 and $28,747 during the three months ended March 31, 2026 and 2025, respectively.

This table contains condensed financial information of LSV:

On April 1, 2026, LSV provided an interest in the partnership to select key employees which reduced the ownership percentage of each existing partner on a pro-rata basis. As a result, the Company's total partnership interest in LSV was reduced slightly to approximately 38.4% from approximately 38.5%.

Other Equity Method Investments

The Company's other equity method investments consist of several firms acquired in December 2025 and during the first quarter 2026 in connection with the Stratos Acquisition (See Note 12) and an investment in a non-affiliated limited partnership fund in which the Company holds a more than minor interest. At March 31, 2026 and December 31, 2025, the value of the equity method entities related to Stratos was $23,738 and $57,153, respectively. At March 31, 2026 and December 31, 2025, the value of the Company's investment in the limited partnership fund was $10,484.

Billings to these clients occur once the asset valuation processes are completed.

Property and Equipment

Property and Equipment on the accompanying Consolidated Balance Sheets consists of:

Note 4 –Fair Value Measurements

The fair value of the Company’s financial assets and liabilities is determined in accordance with the fair value hierarchy. The pricing policies and procedures applied to the Company's Level 1 and Level 2 financial assets during the three months ended March 31, 2026 were consistent with those as described in the Company's Annual Report on Form 10-K at December 31, 2025. Level 1 financial assets and liabilities of the Company and consolidated VIEs consist mainly of equity securities and investments in open-end and closed-end investment products that are quoted daily. Level 2 financial assets primarily consist of Government National Mortgage Association (GNMA) mortgage-backed securities held by the Company's wholly-owned limited purpose federal thrift subsidiary, SEI Private Trust Company (SPTC), and Federal Home Loan Bank (FHLB) and other U.S. government agency short-term notes held by SIDCO. The financial assets held by SIDCO were purchased as part of a cash management program requiring only short term, top-tier investment grade government and corporate securities. The financial assets held by SPTC are debt securities issued by GNMA and are backed by the full faith and credit of the U.S. government. These securities were purchased for the sole purpose of satisfying applicable regulatory requirements and have maturity dates which range from 2027 to 2041. The Company's Level 3 financial liabilities at March 31, 2026 and December 31, 2025 consist entirely of the estimated fair value of the contingent considerations resulting from business acquisitions. There were no transfers of financial assets between levels within the fair value hierarchy during the three months ended March 31, 2026.

The fair value of the Company's investments in funds sponsored by LSV is measured using the net asset value per share (NAV) as a practical expedient. The NAVs of the funds are calculated by the funds' independent custodian and are derived from the fair values of the underlying investments as of the reporting date. The investment funds sponsored by LSV allow for investor redemptions at the end of each calendar month. The investments measured using the NAV as a practical expedient have not been classified in the fair value hierarchy but are presented in the tables below to permit reconciliation to the amounts presented on the accompanying Consolidated Balance Sheets.

The fair value of certain financial assets and liabilities of the Company was determined using the following inputs:

Note 5 –Investments and Other Marketable Securities

Investments on the accompanying Consolidated Balance Sheets consist of:

Available For Sale Debt Securities

The Company's available-for-sale debt securities consist of

Unrealized holding losses, net of income tax benefit, at March 31, 2026 and December 31, 2025 of available-for-sale debt securities were:

The unrealized losses are associated with the Company’s investments in mortgage-backed securities issued by GNMA and were caused by interest rate increases (See Note 4). The contractual cash flows of these securities are guaranteed by an agency of the U.S. government. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost bases of the Company's investments. The Company does not intend to sell the investments and it is not likely that the Company will be required to sell the investments before recovery of their amortized cost bases.

Theunrealized losses, net of unrealized gains, associated with the Company's available-for-sale debt securities are reported as a separate component of Accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets.

The following tables provide the scheduled maturities of the Company's available-for-sale debt securities:

There were no material realized gains or losses from available-for-sale debt securities during the three months ended March 31, 2026 and 2025, respectively.

Investment Products and Equities

The Company's investments in investment products and equities had a fair value of $67,379 and $67,414 at March 31, 2026 and December 31, 2025, respectively. There were no material realized gains or losses during the three months ended March 31, 2026 and 2025, respectively, from investment products and equities.

Investments in Affiliated Funds

Securities Owned

The Company’s broker-dealer subsidiary, SIDCO, has investments in U.S. government agency securities with maturity dates less than one year. These investments are reflected as Securities owned on the accompanying Consolidated Balance Sheets. Due to specialized accounting practices applicable to investments by broker-dealers, the securities are reported at fair value and changes in fair value are recorded in current period earnings. The securities had a fair value of $32,093 and $33,777 at March 31, 2026 and December 31, 2025, respectively. There were no material net gains or losses related to the securities during the three months ended March 31, 2026 and 2025.

Cash Equivalents

Investments in SEI-sponsored and non-SEI-sponsored money market funds and commercial paper classified as cash equivalents had a fair value of $186,032 and $235,933 at March 31, 2026 and December 31, 2025, respectively.

The following tables provide additional information for the three months ended March 31, 2026 and 2025 pertaining to the business segments:

Note 10 –Income Taxes

The gross liability for unrecognized tax benefits at March 31, 2026 and December 31, 2025 was $14,214 and $13,613, respectively, exclusive of interest and penalties, of which $14,308 and $13,577 would affect the effective tax rate if the Company were to recognize the tax benefit.

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of March 31, 2026 and December 31, 2025, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $1,907 and $1,685, respectively.

The effective income tax rate for the three months ended March 31, 2026 and 2025 differs from the federal income tax statutory rate due to the following:

The increase in the effective tax rate for the three months ended March 31, 2026 was primarily due to non-deductible executive compensation. Under Section 162(m) of the Internal Revenue Code, the Company's federal income tax deduction for compensation paid to certain covered employees is limited. Compensation expense that exceeds this limitation is not deductible for income tax purposes but is recognized as expense for financial reporting purposes. As a result, the Company incurred a permanent difference during the three months ended March 31, 2026, which increased the effective tax rate.

The Company files income tax returns in the United States on a consolidated basis and in many U.S. state and foreign jurisdictions. The Company is subject to examination of income tax returns by the Internal Revenue Service (IRS) and other domestic and foreign tax authorities. The Company is no longer subject to U.S. federal income tax examination for years before 2022 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2018.

The Company estimates it will recognize $4,057 of gross unrecognized tax benefits which is expected to be paid within one year or to be removed at the expiration of the statute of limitations and resolution of income tax audits and is netted against the current payable account. These unrecognized tax benefits are related to tax positions taken on certain federal, state, and foreign tax returns. However, the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. While it is reasonably possible that some issues under examination could be resolved in the next twelve months, based upon the current facts and circumstances, the Company cannot reasonably estimate the timing of such resolution or the total range of potential changes as it relates to the current unrecognized tax benefits that are recorded as part of the Company’s financial statements.

Note 11 –Commitments and Contingencies

In the ordinary course of business, the Company from time to time enters into contracts containing indemnification obligations of the Company. These obligations may require the Company to make payments to another party upon the occurrence of certain events including the failure by the Company to meet its performance obligations under the contract. These contractual indemnification provisions are often standard contractual terms of the nature customarily found in the type of contracts entered into by the Company. In many cases, there are no stated or notional amounts included in the indemnification provisions. There are no amounts reflected on the Consolidated Balance Sheets as of March 31, 2026 and December 31, 2025 related to these indemnifications.

Rubicon Wealth Management

As the Company reported in prior filings with the Commission, on May 1, 2024, SEI Private Trust Company (SPTC), a wholly-owned, operating subsidiary of SEI, terminated its client relationship with Rubicon Wealth Management LLC, an SPTC investment advisor client (Rubicon). SPTC terminated the Rubicon relationship due to suspicions of fraudulent activity by Rubicon’s founder, Scott Mason. Mr. Mason and Rubicon were investigated by the U.S. Department of Justice and Securities and Exchange Commission and Mr. Mason pled guilty to several crimes and consented to a judgment being entered against him in both proceedings. On June 25, 2025, Mr. Mason was sentenced to 97 months in prison, followed by three years of supervised release. Mason was also ordered to pay nearly $25,000 in restitution to his victims and more than $2,300 in back taxes to the Internal Revenue Service.

The previously disclosed lawsuits filed against SPTC in its capacity as custodian for the Rubicon accounts of the plaintiffs (collectively, the Rubicon Actions) remain pending in the Court of Common Pleas of Montgomery County, Pennsylvania, and are now in the discovery phase. While the ultimate outcomes of these litigations remain uncertain, SPTC is vigorously defending each of the Rubicon Actions. Currently, SPTC estimates that the aggregate amount of Rubicon client assets transferred at the direction of Mr. Mason from SPTC custodial accounts to accounts of an entity, Orchard Park, that unbeknownst to the investors or SPTC was established and controlled by Mr. Mason and was used by Mr. Mason for personal expenditures is approximately $15,000. In the event that SPTC is unsuccessful in its defense of the Rubicon Actions, SEI does not currently believe that the losses associated with such unsuccessful defense would exceed the approximately $15,000 of Rubicon client assets that Mr. Mason directed to be transferred to Orchard Park.

LSV Asset Management

On January 27, 2026, the Company, and its wholly owned subsidiary, SEI Funds, Inc., (the SEI Parties) were joined as defendants in Qu v. LSV Asset Management, an Illinois State Court action originally filed in July 2024 in Cook County, Illinois Circuit Court (the Qu Litigation). The Qu Litigation alleged that LSV Asset Management (LSV), and certain of its executives (the LSV Defendants), breached fiduciary duties and implied covenants of good faith with respect to LSV’s purchase of LSV partnership interest indirectly held by the plaintiff. The claim against the SEI Parties alleges that the Company, through its wholly owned subsidiary SEI Funds, Inc., that is the owner of a minority interest of LSV, aided and abetted the LSV Defendant’s alleged breach of fiduciary duty.

While the outcome of this litigation remains uncertain, the LSV Defendants and the Company believe that the LSV Defendants have valid defenses to plaintiffs’ primary claims, and the Company believes that that the aiding and abetting claim against the Company are even more attenuated with valid defenses. The Company intends to defend the allegations in the Qu Litigation vigorously. Based upon the early nature of the litigation against the Company, the vagueness of the alleged conduct by the SEI Parties, and the lack of clarity of what portion of the alleged losses for which the Company would be liable in the unlikely event that the plaintiffs are successful in their theories of liability, the Company is not reasonably able to provide an estimate of loss, if any, with respect to the matters alleged in the Qu Litigation.

SEI Capital Accumulation Plan

On December 26, 2025, a class action complaint was filed in the United States District Court for the Eastern District of Pennsylvania by David Hall and Jennifer Knapp, individually and as representatives of similarly situated persons, and on behalf of the SEI Capital Accumulation Plan (the Plan), naming the Company and its affiliated and/or related entities SEI Investments Management Corporation, SEI Capital Accumulation Plan Administration Committee, and John Does 1-30 as defendants (the Hall Complaint). The Hall Complaint seeks damages for defendants’ alleged breach of fiduciary duties under ERISA with respect to selecting and monitoring certain of the Plan’s investment options, which are affiliated investment products.

While the outcome of this litigation remains uncertain, defendants believe that they have valid defenses to plaintiffs’ claims and intend to defend the allegations contained in the Hall Complaint vigorously. At this stage of the litigation, the Company is not reasonably able to provide an estimate of loss, if any, with respect to the matters set forth in the Hall Complaint.

United Kingdom Financial Conduct Authority Supervisory Review of SEI Investments (Europe) Limited

As previously reported, on July 31, 2024, SEI Investments (Europe) Limited (SIEL), an indirectly, wholly-owned operating subsidiary of SEI, received a final requirement notice from the Financial Conduct Authority of the United Kingdom (the FCA) under section 166(3)(a) of the Financial Services and Markets Act 2000 (FSMA), requiring SIEL to engage a “Skilled Person” to undertake a two-stage review of SIEL’s governance arrangements and control environment.

The VREQ currently imposed on SIEL is reflected in full on the FCA Register.

SIEL is fully committed to addressing the concerns raised by the FCA. The Company believes the actions SIEL is taking to remediate the issues identified in the Skilled Person Report will not only strengthen its business but also help maintain its focus on achieving positive customer outcomes, positioning SIEL for sustainable future growth.

SIEL management believes that the remediation actions currently underway will appropriately address the recommendations made by the Skilled Person and concerns articulated by the FCA in respect of the issues identified by the Skilled Person. SIEL’s remediation actions will be reviewed by the Skilled Person as part of the second stage of their engagement.

The VREQ will stay in effect unless and until varied or cancelled by the FCA (either on the application of SIEL or of the FCA’s own volition), until the FCA is satisfied that SIEL has demonstrated that it has addressed the concerns the FCA has communicated to it.

Equilus Capital

On April 1, 2026 the Washington Department of Financial Institutions (DFI) filed a lawsuit in Washington Superior Court (the Complaint) seeking a temporary restraining order, injunctive relief, and the appointment of a receiver against Equilus Group, Inc. (Equilus Group), Equilus Capital Partners, LLC (Equilus Capital, and together with Equilus Group, the Equilus Companies), Joel Frank (a managing member of the Equilus Companies), certain entities controlled by Joel Frank and/or the Equilus Companies (the Equilus Funds), and certain other named individual defendants (the Equilus Parties). Equilus

Group is a Washington State registered investment adviser that is a client of the Company's Investment Advisors segment. The DFI alleges that Joel Frank, the Equilus Companies, and the Equilus Funds engaged in Ponzi scheme-like activity and/or other wrongful conduct, selling approximately $39,000 in unregistered securities and alleging theft from individual investors who purchased such securities of at least approximately $800.

The Complaint names SPTC, along with several other financial institutions, as a financial institution defendant for the purposes of obtaining a temporary restraining (TRO) against the financial institution defendants in order to prohibit such financial institution defendants from allowing any activity to occur in Equilus accounts maintained by the financial institution defendants. SPTC maintains investment accounts for certain Equilus Parties and Equilus Group investors. DFI obtained the TRO ex parte on April 9, 2026. The TRO, with which SPTC is fully-complying, instructs SPTC to freeze Equilus-controlled accounts pending appointment of a receiver. On April 10, 2026, the DFI suspended Equilus Group’s Washington state investment adviser registration, with intent to revoke. No claims have been made against SPTC and the Company is not aware of any allegations of wrongdoing by the Company or SPTC.

Other Matters

The Company and certain of its subsidiaries are party to various other examinations, investigations, actions and claims arising in the normal course of business that the Company does not believe are material. The Company believes that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial position or the manner in which the Company conducts its business. Currently, the Company does not believe the amount of losses associated with these matters can be estimated. While the Company does not believe that the amount of such losses will, when liquidated or estimable, be material to its financial position, the assumptions may be incorrect and any such loss could have a material adverse effect on the Company's results of operations or the manner in which the Company conducts its business in the period(s) during which the underlying matters are resolved.

Unfunded Commitments to Limited Partnership Funds

The Company has unfunded commitments of $8,924 at March 31, 2026 to limited partnership funds.

Unused Letters of Credit

As of March 31, 2026, the Company had outstanding and unused letters of credit of $4,630 under its Credit Facility (See Note 6). The letters of credit were issued for certain municipal requirements related to the expansion of the Company's corporate headquarters and are due to expire in 2026. The Company does not expect that any material amounts will be drawn under these letters of credit. Accordingly, no liability has been recorded in the accompanying Consolidated Balance Sheets.

Note 12 –Business Acquisitions and Divestitures

Stratos Wealth Holdings

On July 17, 2025, SEI-Eclipse Holding Company, LLC (SEI-Eclipse), a newly-formed, wholly-owned indirect subsidiary of the Company, and the Company entered into a definitive agreement (as amended, the Acquisition Agreement) with Stratos Wealth Holdings, LLC (Stratos) and Stratos Intermediate Holdco I, LLC (Stratos US Holdings) to acquire a controlling interest in the businesses operated by Stratos. Stratos is a holding company that directly and indirectly holds 100.0% of the equity of certain subsidiary holding companies (including Stratos US Holdings), which, in turn, own equity interests in multiple operating companies that form a network of over 350 affiliated financial advisors in the U.S. and Mexico. The transaction is designed to be completed by SEI-Eclipse in two stages. The first stage is the acquisition of all of the outstanding equity of Stratos US Holdings, which directly owns equity interests in the U.S.-based Stratos operating entities. The second stage is an option to acquire all of the outstanding equity of the Stratos subsidiary holding company (Stratos NSC Holdings) that directly owns a controlling interest in NSC Asesores, S.C., the Mexico-based operating entity (NSC Asesores). The due diligence process regarding Stratos NSC Holdings and NSC Asesores is still ongoing and the Company has not yet determined if it will cause SEI-Eclipse to exercise the second stage option.

On December 3, 2025 (the Closing Date), SEI-Eclipse closed the first stage of the transaction by acquiring all of the outstanding equity of Stratos US Holdings. The acquisition consideration was comprised of cash of $323,102, funded by a cash contribution by the Company to SEI-Eclipse, and the issuance of 42.5% of the common units of SEI-Eclipse with an estimated fair value of $235,145 (the Stratos Acquisition). As a result, the Company indirectly owns a 57.5% controlling interest in SEI-Eclipse and certain Stratos equity holders own the remaining 42.5% of SEI-Eclipse through an aggregator entity (Stratos Aggregator). This 42.5% minority interest of SEI-Eclipse held by Stratos Aggregator is subject tothree equal put/call options by SEI-Eclipse or Stratos Aggregator exercisable at 36 months,54 months and 72 months after the Closing Date, and is presented as redeemable non-controlling interest on the accompanying Consolidated Balance Sheets. If the puts or calls are fully exercised, it will result in the Company indirectly owning 100.0% of the outstanding equity of SEI-Eclipse.

The Company accounted for the Stratos Acquisition as a business combination using the acquisition method of accounting in accordance with ASC 805 (See Note 1). The purchase price has been preliminarily allocated to the tangible assets and identifiable intangible assets acquired and liabilities assumed, based upon their estimated fair values, with the exception of the following: (1) deferred income tax assets acquired and liabilities assumed are recognized and measured in accordance with ASC 740, Income Taxes; (2) contract assets and liabilities are measured and recognized in accordance with ASC 606, Revenue from Contracts with Customers; and (3) certain lease related assets and liabilities which are measured and recognized in accordance with ASC 842, Leases. In addition, the redeemable non-controlling interest was recorded at fair value under ASC 805.

As part of the Stratos Acquisition, the Company, via its 57.5% indirect interest in SEI-Eclipse, acquired a portfolio of minority equity investments which were accounted for under ASC 323, Investments - Equity Method and Joint Ventures as of the Closing Date due to the Company having significant influence. These investments were determined to have an acquisition date fair value of $56,974. For certain equity method investments, the Company, via its 57.5% indirect interest in SEI-Eclipse, also acquired rights to obtain a controlling interest in the investees. These contractual rights were previously negotiated between Stratos Wealth Enterprises, LLC, one of the U.S.-based Stratos operating entities (SWE), and the equity method investee controlling interest holders and were contingently exercisable upon a change of control of Stratos. The purchase price under the contractual rights is based on a proscribed formula tied to historical profitability of the applicable equity method investee. The Company determined that the fair value of these rights was de minimis on the Closing Date.

The Company has not finalized its accounting for any areas of the purchase price allocation related to the Stratos business. The Company anticipates it will finalize its accounting for the Stratos Acquisition during the fourth quarter of 2026. The Company will make adjustments to the purchase price allocation prior to completion of the measurement period, as required.

Given the Company’s intent to cause SWE to exercise its contractual rights to acquire controlling interests in the equity method investees and to close on the purchases contemplated after the Closing Date, the Company deposited $118,606 in escrow on the Closing Date.

The Acquisition Agreement also provides for SEI-Eclipse to acquire the outstanding equity of Stratos NSC Holdings held by Stratos US Holdings for approximately $103,000. The future closing of the acquisition of Stratos NSC Holdings, if any, is subject to applicable regulatory approval and other closing conditions, including, without limitation, the Company receiving satisfactory results of its due diligence of Stratos NSC Holdings and NSC Asesores.

The following unaudited pro forma consolidated financial information reflects the results of operations of the Company for the three months ended March 31, 2026 and 2025 as if the Stratos Acquisition had occurred as of January 1, 2025, after giving effect to certain purchase accounting adjustments. These amounts are based on financial information of the Stratos business and are not necessarily indicative of what the Company’s operating results would have been had the Stratos Acquisition taken place on January 1, 2025:

The unaudited pro forma consolidated financial information includes certain nonrecurring adjustments directly attributable to the Stratos Acquisition. These adjustments primarily relate to transaction‑related costs and were immaterial.

Acquisition of Equity Method Investments (EMI Entities)

During the three months ended March 31, 2026, SWE used cash funded from the deposit account to purchase 100% interest ofnine entities and a majority interest intwo additional entities (collectively, “the EMI Entities”) through the exercise of its contractual rights noted above. The following table summarizes the preliminary estimated purchase consideration for the EMI Entities:

The promissory notes have interest rates ranging from 3.67% to 4.67% and are payable in 12 to 16 quarterly installments ranging between April 30, 2026 and April 30, 2030. The expected cash payments under the promissory notes are fully funded as part of the deposit account described above.

Each EMI entity acquired is subject to a lookback provision (Revenue Clawback) which provides for the seller to reimburse the buyer should the trailing twelve month gross revenue calculated eighteen months following the respective closing dates falls below 95% of Target Gross Revenue (as defined in the respective agreements). Any contingent consideration owed will be settled through a reduction of the respective promissory note. If the amount of the adjustment is greater than the amount owed under the respective promissory note, a payment is owed from the respective seller. These Revenue Clawbacks are contingent consideration which values will be adjusted to fair value each subsequent reporting period.

The following table summarizes the preliminary estimated fair values of the assets acquired, liabilities assumed, and non-controlling interest for the EMI Entities as of March 31, 2026:

The excess of the purchase price and the fair value of the non-controlling interest over the tangible and intangible assets acquired and liabilities assumed has been recorded as goodwill. The Company has assigned the provisional goodwill of $33,665 to its Investment Advisors reportable segment. The resulting goodwill is primarily due to the perceived growth potential of the acquired business, plus the fair value of the assembled workforce. Any goodwill generated for income tax purposes from the acquisition is fully deductible.

The results of operations for the acquired EMI Entities are included in the consolidated financial statements of the Company from the date of the acquisition.

The Company has identified the following significant intangible assets acquired: trade names, unpatented technology, client relationships, and non-compete agreements. The following table summarizes the preliminary fair value of the significant identifiable intangible assets:

The provisional fair values of identifiable intangible assets were determined by using certain estimates and assumptions that are not observable in the market. Determining the useful life of an intangible asset also requires judgment, as different types of intangible assets will have different useful lives.

The fair value of the identified intangible assets and the non-controlling interests were determined using the same methodology and key assumptions as those disclosed in the Annual Report on Form 10-K for the year ended

December 31, 2025.

The acquisition of certain EMI Entities triggered a provision in the Stratos Acquisition agreement whereby the Company has a contractual right to receive additional amounts from the Stratos sellers based on the future performance of the acquired EMI Entities. The Company is entitled to an amount from the SEI-Eclipse non-controlling interest holders should there be an EBITDA shortfall at any of the EMI Entities. The amount of a shortfall is calculated on an entity-by-entity basis based on a stated multiple and the difference between theeighteen-month prior quarter annualized EBITDA less the closing date EBITDA. The amount payable under this EBITDA clawback is reduced by the amount of the promissory note forgiveness under the revenue based contingent consideration arrangement described above. The amount payable by the SEI-Eclipse non-controlling interest holders can be funded, at the election of the SEI-Eclipse non-controlling interest holder, through i) cash payment to the Company or ii) issuance of preferred units of SEI-Eclipse to the Company.

The Company has not finalized its accounting for any areas of the purchase price allocation related to the EMI Entities. As a result, the amounts presented in the table above are preliminary. The Company anticipates it will finalize its accounting for the EMI Acquisition during the fourth quarter of 2026. The Company will make adjustments to the purchase price allocation prior to completion of the measurement period, as required.

Note 13 –Goodwill and Intangible Assets

The changes in the carrying amount of the Company's goodwill by segment are as follows:

The Company recognized $9,197 and $3,449 of amortization expense related to acquired intangible assets during the three months ended March 31, 2026 and 2025, respectively.

Note 14 –Revenues from Contracts with Customers

The Company’s principal sources of revenues are: (1) asset management, administration and distribution fees primarily earned based upon a contractual percentage of net assets under management or administration; and (2) information processing and software servicing fees that are either recurring and primarily earned based upon the number of trust accounts being serviced or a percentage of the market value of the clients' assets processed on the Company's platforms, or non-recurring and based upon project-oriented contractual agreements related to client implementations.

Note 15 –Consolidated Variable Interest Entities

On July 31, 2025, the Company made a seed capital investment of $50,000 through a subscription agreement with the LSV Global Equity Market Neutral Fund, LP (LSV GEMNF), a limited partnership fund that was operationalized on July 1, 2025. LSV serves as the general partner and investment manager to the LSV GEMNF and makes all operational and investment decisions on behalf of the fund. LSV does not have a partnership interest in the LSV GEMNF.

The Company determined the LSV GEMNF to be a variable interest entity (VIE) in which it has a variable interest through its direct equity partnership interest and also determined LSV does not have a variable interest through its management fee as general partner to the fund. The Company concluded that it is the primary beneficiary as substantially all of the activities of the fund are currently conducted on behalf of the Company while the fund is in the seed capital stage and is therefore required to consolidate the accounts of the LSV GEMNF into its financial statements.

The Company recognized unrealized gains of $1,500 during the three months ended March 31, 2026 from the change in fair value of the seed capital investment in the LSV GEMNF. These gains are included in Net gain from consolidated variable interest entities on the accompanying Consolidated Statement of Operations.

The assets and liabilities of the LSV GEMNF presented on the accompanying Consolidated Balance Sheets consist of:

The assets presented in the table above may only be used to settle obligations of the LSV GEMNF and are not available for use by the Company to the extent they are held by non-controlling interests. Any debt or liabilities of the LSV GEMNF have no recourse to the Company’s general credit.
