Revenues from investment management services are recognized in Asset management, administration and distribution fees on the accompanying Consolidated Statements of Operations.

**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 September 30, 2025, the results of operations for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024. 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, 2024.

There have been no significant changes in significant accounting policies during the nine months ended September 30, 2025 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

**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**

The Company includes redeemable non-controlling interests related to consolidated VIEs as temporary equity on the Consolidated Balance Sheets. Non-controlling interests in consolidated VIEs are subject to redemption by the 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 in consolidated VIEs are as follows:

---

| | |
|:---|:---|
| | Redeemable Non-controlling Interests |
| Balance, December 31, 2024 | $— |
| Net income attributable to non-controlling interests | 382 |
| Capital contributions from non-controlling interests | 18470 |
| Balance, September 30, 2025 | $18852 |

---

**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 $5,397 and $1,202 in fees during the three months ended September 30, 2025 and 2024, respectively. During the nine months ended September 30, 2025 and 2024, the Company waived $14,792 and $6,764, respectively, in fees.

**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 $191,938 and $341,311 at September 30, 2025 and December 31, 2024, 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. Cash and cash equivalents also includes restricted cash of $250 at September 30, 2025 and December 31, 2024 segregated for regulatory purposes related to trade-execution services conducted by SEI Investments (Europe) Limited and $52 at September 30, 2025 and December 31, 2024 segregated in special reserve accounts for the benefit of customers of the Company's broker-dealer subsidiary, SEI Investments Distribution Co. (SIDCO), in accordance with certain rules established by the Securities and Exchange Commission (SEC) for broker-dealers.

**Capitalized Software**

The Company capitalized $22,828 and $18,414 of software development costs during the nine months ended September 30, 2025 and 2024, respectively, to further develop the SEI Wealth Platform<sup>SM</sup> (SWP) and for the development of a new platform for the Investment Managers segment. The Company capitalized $14,510 and $10,542 of software development costs for significant enhancements to SWP during the nine months ended September 30, 2025 and 2024, respectively. As of September 30, 2025, the net book value of SWP was $197,528, which includes $1,862 of capitalized software development costs in-progress associated with future releases. SWP has a weighted average remaining life of 7.7 years. Amortization expense for SWP was $21,602 and $20,517 during the nine months ended September 30, 2025 and 2024, respectively.

The Company also capitalized $8,318 and $7,872 of software development costs during the nine months ended September 30, 2025 and 2024, 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 with an estimated useful life of 7.0 years. The net book value of the platform at September 30, 2025 was $38,031, which includes $8,319 of capitalized software development costs in-progress associated with future releases. Amortization expense for the platform was $1,100 during the nine months ended September 30, 2025.

**Earnings per Share**

The calculations of basic and diluted earnings per share for the three and nine months ended September 30, 2025 and 2024 are:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Three Months Ended September 30, | Three Months Ended September 30, | Nine Months Ended September 30, | Nine Months Ended September 30, |
| | 2025 | 2024 | 2025 | 2024 |
| Net income | $164586 | $154900 | $543186 | $425420 |
| Less: Net income attributable to non-controlling interests | 382 |  | 382 |  |
| Net income attributable to SEI Investments Company | $164204 | $154900 | $542804 | $425420 |
| Shares used to compute basic earnings per common share | 123099000 | 129418000 | 124710000 | 130550000 |
| Dilutive effect of stock awards | 3226000 | 1253000 | 2974000 | 1280000 |
| Shares used to compute diluted earnings per common share | 126325000 | 130671000 | 127684000 | 131830000 |
| Basic earnings per common share | $1.33 | $1.20 | $4.35 | $3.26 |
| Diluted earnings per common share | $1.30 | $1.19 | $4.25 | $3.23 |

---

During the three months ended September 30, 2025 and 2024, employee stock options to purchase 5,687,000 and 10,606,000 shares of common stock with an average exercise price of $66.09 and $61.06, respectively, were outstanding but not included in the computation of diluted earnings per common share. During the nine months ended September 30, 2025 and 2024, employee stock options to purchase 5,744,000 and 10,747,000 shares of common stock with an average exercise price of $66.04 and $61.05, respectively, were outstanding but not included in the computation of diluted earnings per common share. These options for the three and nine 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 December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures (ASU 2023-09) to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 on a prospective basis. Early adoption is permitted. The Company does not expect ASU 2023-09 to have a significant impact on its annual consolidated financial statements and related disclosures.

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.

**Reclassifications**

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

**Note 2 – Equity Method Investments**

**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 September 30, 2025 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.

At September 30, 2025 and December 31, 2024, the Company's total investment in LSV was $52,083 and $114,299, 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 $104,768 and $112,476 in the nine months ended September 30, 2025 and 2024, 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 $31,903 and $36,513 during the three months ended September 30, 2025 and 2024, respectively. During the nine months ended September 30, 2025 and 2024, the Company's proportionate share in the earnings of LSV was $94,290 and $102,375, respectively.

---

On April 1, 2025, 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 38.5% from approximately 38.6%.

**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 nine months ended September 30, 2025 were consistent with those as described in the Company's Annual Report on Form 10-K at December 31, 2024. 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 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 September 30, 2025 and December 31, 2024 consist entirely of the estimated fair value of the contingent

------

considerations resulting from business acquisitions (See Note 12). The fair value of the contingent considerations were determined using a Monte-Carlo simulation model. There were no transfers of financial assets between levels within the fair value hierarchy during the nine months ended September 30, 2025.

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 and consolidated VIEs was determined using the following inputs:

Net unrealized losses at September 30, 2025 of available-for-sale debt securities were $3,977 (net of income tax benefit of $1,188). Net unrealized losses at December 31, 2024 of available-for-sale debt securities were $8,536 (net of income tax benefit of $2,549). These 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. These net unrealized losses 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:

**Note 6 – Line of Credit**

On August 18, 2025 (the Closing Date), the Company entered into a five-year $500,000 Credit Agreement (the Facility) with U.S. Bank National Association, and a syndicate of other lenders. The Facility is scheduled to expire in August 2030, at which time any aggregate principal amount of loans outstanding becomes payable in full. The aggregate principal

------

amount of the Facility may be increased by an additional $250,000 under certain conditions set forth in the agreement. The Facility replaces the Company's $325,000 five-year credit facility that was scheduled to expire in April 2026. Interest on borrowings under the Facility is payable at rates that, at the Company's option, are based on a base rate (the Base Rate) plus a premium that can range from 0.25% to 1.25% or the Term Secured Overnight Financing Rate (Term SOFR) plus a premium that can range from 1.25% to 2.25% depending on the Company's Leverage Ratio (a ratio of consolidated indebtedness to consolidated EBITDA for the four preceding fiscal quarters, all as defined in the relevant agreement). The Base Rate is defined as the highest of a) the Prime Rate, b) the Federal Funds Rate (each as defined in the relevant agreement) plus 0.50%, or c) Term SOFR for a one-month tenor in effect on such day plus 1.00%. The Company also pays quarterly commitment fees based on the unused portion of the Facility. The quarterly fees for the Facility can range from 0.15% of the amount of the unused portion of the Facility to 0.35%, depending on the Company's Leverage Ratio. Certain wholly-owned subsidiaries of the Company have guaranteed the obligations of the Company under the Facility.

The Company may issue up to $25,000 in letters of credit under the terms of the Facility. The Company pays a periodic commission fee based on the applicable rate with respect to borrowings that are designated as SOFR Loans (as defined in the relevant agreement) plus an issuance fee agreed upon between between the Company and the lender.

The Facility contains covenants that, among other things, restrict the ability of the Company and its subsidiaries to engage in mergers, consolidations, asset sales, acquisitions, transactions with affiliates, or to incur indebtedness or liens, subject in certain cases to certain exceptions and thresholds, as defined in the related agreement. In the event of a default under the Facility, the Company would also be restricted from paying dividends on, or repurchasing, its capital stock without the approval of the lenders. Upon the occurrence of certain financial or economic events, significant corporate events or certain other events of default constituting an event of default under the Facility, all loans outstanding under the Facility may be declared immediately due and payable and all commitments under the Facility may be terminated.

The Company was in compliance with all covenants of the credit facilities during the nine months ended September 30, 2025. As of October 9, 2025, the Company had outstanding letters of credit of $4,630 under the Facility. The amount of the Facility that is available for general corporate purposes as of October 9, 2025 was $495,370.

**Note 7 – Shareholders' Equity**

**Stock-Based Compensation**

The Company has non-qualified stock options and restricted stock units (RSUs) outstanding under its equity compensation plans. The Company recognized stock-based compensation expense in its Consolidated Financial Statements in the three and nine months ended September 30, 2025 and 2024, respectively, as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Three Months Ended September 30, | Three Months Ended September 30, | Nine Months Ended September 30, | Nine Months Ended September 30, |
| | 2025 | 2024 | 2025 | 2024 |
| Stock-based compensation expense | $13956 | $13696 | $41985 | $37224 |
| Less: Deferred tax benefit | (2561) | (2616) | (7737) | (7201) |
| Stock-based compensation expense, net of tax | $11395 | $11080 | $34248 | $30023 |

---

The vesting of the Company's RSUs are time-based and are not based on the achievement of performance targets. The majority of the Company's RSUs will vest on the third anniversary of the issuance date. All outstanding stock options have performance-based vesting provisions that tie the vesting of stock options to the Company's financial performance which are established at the time of grant, as well as a service condition which requires a minimum waiting period from the date of grant. The performance targets are measured annually on December 31. The amount of stock-based compensation expense recognized in the period is based upon management's estimate of when the financial vesting targets may be achieved. Any change in management's estimate could result in the remaining amount of stock-based compensation expense to be accelerated, spread out over a longer period, or reversed. This may cause volatility in the recognition of stock-based compensation expense in future periods and could materially affect the Company's earnings.

As of September 30, 2025, there was approximately $76,543 of unrecognized compensation cost remaining related to unvested employee stock options and restricted stock units that management expects will vest and is being amortized.

The Company issues new common shares associated with the exercise of stock options. The total intrinsic value of options exercised during the nine months ended September 30, 2025 was $50,667. The total options exercisable as of September 30, 2025 had an intrinsic value of $174,633. The total intrinsic value for options exercisable is calculated as the difference between the market value of the Company's common stock as of September 30, 2025 and the weighted average exercise price of the options. The market value of the Company's common stock as of September 30, 2025 was $84.85 as reported by the Nasdaq Stock Market, LLC. The weighted average exercise price of the options exercisable as

------

of September 30, 2025 was $59.15. Total options that were outstanding as of September 30, 2025 were 13,335,000. Total options that were exercisable as of September 30, 2025 were 6,795,000.

**Common Stock Buyback**

The Company's Board of Directors, under multiple authorizations, has authorized the repurchase of common stock on the open market or through private transactions. The Company purchased 6,235,000 shares at a total cost of $515,156 during the nine months ended September 30, 2025, which reduced the total shares outstanding of common stock. The cost of stock purchases during the period includes the cost of excise taxes applicable to stock repurchases and certain transactions that settled in the following quarter. As of September 30, 2025, the Company had approximately $154,443 of authorization remaining for the purchase of common stock under the program.

The Company immediately retires its common stock when purchased. Upon retirement, the Company reduces Capital in excess of par value for the average capital per share outstanding and the remainder is charged against Retained earnings. If the Company reduces its Retained earnings to zero, any subsequent purchases of common stock will be charged entirely to Capital in excess of par value.

**Cash Dividend**

On May 28, 2025, the Board of Directors declared a cash dividend of $0.49 per share on the Company's common stock, which was paid on June 17, 2025, to shareholders of record on June 9, 2025. Cash dividends declared during the nine months ended September 30, 2025 and 2024 were $61,478 and $60,285, respectively.

**Note 10 – Income Taxes**

The gross liability for unrecognized tax benefits at September 30, 2025 and December 31, 2024 was $16,663 and $15,241, respectively, exclusive of interest and penalties, of which $16,938 and $14,886 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 September 30, 2025 and December 31, 2024, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $2,512 and $1,725, respectively.

| Total gross uncertain tax positions | $19175 | $16966 |

The effective income tax rate for the three and nine months ended September 30, 2025 and 2024 differs from the federal income tax statutory rate due to the following:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Three Months Ended September 30, | Three Months Ended September 30, | Nine Months Ended September 30, | Nine Months Ended September 30, |
| | 2025 | 2024 | 2025 | 2024 |
| Statutory rate | 21.0% | 21.0% | 21.0% | 21.0% |
| State taxes, net of federal tax benefit | 2.7 | 2.9 | 2.7 | 2.9 |
| Foreign tax expense and tax rate differential | (0.1) | 0.1 | (0.1) | 0.1 |
| Tax benefit from stock option exercises | (1.0) | (0.1) | (0.8) | (0.4) |
| Other, net | (0.7) | (0.4) | (0.5) | (0.2) |
|  | 21.9% | 23.5% | 22.3% | 23.4% |

---

The decrease in the effective tax rates for the three and nine months ended September 30, 2025 was primarily due to higher tax benefits related to stock option exercises and a decline in state effective tax rates.

On July 4, 2025, President Donald J. Trump signed new tax legislation known as the One Big Beautiful Bill Act (OBBBA) into law which makes permanent many of the provisions enacted in 2017 as part of the Tax Cuts and Jobs Act that were scheduled to expire at the end of 2025. The enactment of the OBBBA primarily impacted the Company's the deferred tax liability and income tax payable related to the provisions for the elimination of the capitalization of onshore research and development costs (Section 174) and the reintroduction of 100% bonus depreciation (Section 168) and did not have a significant impact to 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 2021 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 $4,294 of gross unrecognized tax benefits. This amount 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 September 30, 2025 and December 31, 2024 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. 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, with one in the preliminary objection/motion to dismiss stage and the others just beginning their discovery phase. While the Rubicon Actions are in their early stages and the ultimate outcomes of these litigations remain uncertain, SPTC intends to vigorously defend 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 Orchard Park bank accounts 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.

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

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. In the first stage, the Skilled Person is to provide SIEL and the FCA with a report setting out the Skilled Person's view of the effectiveness of the control environment and governance arrangements with respect to key risks, as well as the Skilled Person's recommendations where necessary to address any identified weaknesses (the Section 166 Report). In the second stage, the Skilled Person is to provide an independent view of the quality and completeness of the remediation carried out by SIEL to address any findings from the initial stage and any self-identified weaknesses, including a view on SIEL's compliance with relevant regulations. The appointment of a Skilled Person is one of the regulatory tools used by the FCA to supervise and monitor firms it regulates. A Skilled Person is an independent third-party expert with the relevant knowledge and experience to undertake a review as described above. This is not an enforcement action nor an investigation but an action taken as part of its supervisory oversight.

In August 2024, SIEL, with the approval of FCA, appointed the firm of Grant Thornton to act as the Skilled Person.

On December 16, 2024, Grant Thornton delivered the first stage of its Skilled Person Report in which it concluded, in summary, that SIEL has an established corporate governance framework and risk management framework that it considered to be appropriate in design for the relative size and complexity of its activities. The Skilled Person Report did however make a number of recommendations for improvements in its governance arrangements with its U.S. parent, and with respect to SIEL's three lines of defense: resourcing of control functions, strategy and culture.

To provide the necessary assurance to the FCA of SIEL's focus on addressing the recommendations and concerns, on February 26, 2025, SIEL voluntarily applied to the FCA under section 55L(5)(a) FSMA for the imposition by the FCA of requirements on its regulatory permission ("Voluntary Requirement" / "VREQ"). From February 26, 2025, onwards, SIEL may not, without the FCA's prior written consent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into new client agreements (contracts) where a material change in SIEL's existing suite of propositions, systems or services is required or where significant senior management engagement would be needed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• launch a new proposition, product or service that is not already offered by SIEL.

The VREQ does not prevent SIEL from on-boarding new clients where this does not result in significant new service requirements or significant senior management engagement.

------

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.

**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 $10,648 at September 30, 2025 to limited partnership funds.

**Note 12 – Business Acquisitions and Divestitures**

**Stratos Wealth Holdings**

On July 17, 2025, the Company entered into a definitive agreement with Stratos Wealth Holdings (Stratos), a family of companies focused on supporting the success of financial advisors across business models and affiliation structures. As part of the transaction, a newly formed entity will purchase the operating entities comprising the current Stratos business. The Company will pay a total cash consideration of approximately $527,000 for 57.5% of the equity of this entity. Certain legacy Stratos equity holders will continue to own 42.5%, which is subject to three equal put/call options at 36 months, 54 months and 72 months post-closing that, if fully exercised, will result in the Company owning 100.0% of the entity. Subject to applicable regulatory approval and other customary closing conditions, the transaction is expected to close in two stages: the U.S.-based Stratos business, representing approximately 80.0% of the transaction value, and the Mexico-based NSC business.

The strategic investment in Stratos is not a significant acquisition of assets or otherwise material to the operations or financial results of the Company.

**LifeYield**

In December 2024, the Company acquired LifeYield, LLC (LifeYield). The total purchase price for LifeYield included a contingent consideration subject to the achievement of certain post-closing performance measurements determined during a time period up to four years from the closing date. During the nine months ended September 30, 2025, the Company recorded an adjustment of $1,109 to finalize the calculation of the contingent consideration which reduced the amount of goodwill recorded through the acquisition. Also during the nine months ended September 30, 2025, the Company made an adjustment of $1,467 which reduced the fair value of the contingent consideration. This fair value adjustment to the contingent consideration is reflected in Facilities, supplies and other costs on the Consolidated Statement of Operations. As of September 30, 2025, the contingent consideration of $9,252 is included in Other long-term liabilities on the accompanying Consolidated Balance Sheet.

**XPS Pensions (Nexus) Limited**

In November 2023, the Company's wholly-owned operating subsidiary in the United Kingdom, SIEL, acquired all of the outstanding equity of XPS Pensions (Nexus) Limited, principal employer and scheme funder of the National Pensions Trust (NPT), from its parent company, XPS Pensions Group PLC (XPS). The total purchase price for XPS Pensions (Nexus) Limited included a contingent consideration payable to the sellers subject to the achievement of certain post-closing performance measurements determined during intervals occurring within two years immediately following the

------

closing date. During the second quarter 2025, the Company determined the achievement of the performance measurements would not be met and wrote off $2,587 representing the remaining balance of the contingent consideration obligation to the sellers. The gain from the write off of the contingent consideration is reflected in Facilities, supplies and other costs on the Consolidated Statement of Operations.

**Family Office Services**

On February 27, 2025, the Company announced the entry into a definitive agreement with Aquiline Capital Partners LP (Aquiline) to acquire the Company's Family Office Services business. On June 30, 2025, all conditions subject to closing the transaction were satisfied. The Company received gross proceeds of $116,020 from the sale and recognized a gain of $94,412, net of transaction costs and certain other purchase price adjustments. The Company's gain from the divestiture is included in Gain on sale of business on the accompanying Consolidated Statement of Operations. Prior to the divestiture, the results of operations of the Family Office Services business were reported in the Company's Investments in New Businesses segment.

The Company recognized $9,774 and $10,066 of amortization expense related to acquired intangible assets during the nine months ended September 30, 2025 and 2024, 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 $1,463 during the third quarter 2025 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:

---

|:---|:---|
| Assets of Consolidated Variable Interest Entities | September 30, 2025 |

The following items had a significant impact on our financial results for the three and nine months ended September 30, 2025 and 2024:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The sale of the Family Office Services business was completed on June 30, 2025 resulting in a net gain of $94.4 million, or $0.58 diluted earnings per share recorded in the second quarter 2025. The gain from the sale is reflected in Gain on sale of business on the accompanying Consolidated Statement of Operations (See caption titled "Divestiture of Family Office Services Business" later in this discussion).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue from Assets under management, administration, and distribution fees increased in the first nine months of 2025 primarily from higher assets under administration due to cross sales to existing alternative investment clients of the Investment Managers segment as well as new sales within the segment. Average assets under administration increased $131.6 billion, or 13%, to $1.1 trillion during the first nine months of 2025, as compared to $998.4 billion during the first nine months of 2024.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue from Asset management, administration and distribution fees also increased from market appreciation and positive cash flows into separately managed account programs and Strategist programs of the Investment Advisors segment. This was partially offset by negative cash flows from SEI fund programs and fee reductions in separately managed account programs during 2024. Revenue growth was also partially offset by client losses in the Institutional Investors segment. Average assets under management in equity and fixed income programs, excluding LSV, increased $9.0 billion, or 5%, to $186.9 billion in the first nine months of 2025 as compared to $177.9 billion during the first nine months of 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Fees from the SEI Integrated Cash Program of the Investment Advisors segment increased to $62.3 million during the first nine months of 2025 as compared to $30.4 million during the first nine months of 2024 due to the expansion of the program in late 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue from Information processing and software servicing fees increased in the first nine months of 2025 primarily from new client conversions and growth from existing SEI Wealth Platform<sup>SM</sup> (SWP) clients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Earnings from LSV decreased to $94.3 million in the first nine months of 2025 as compared to $102.4 million in the first nine months of 2024 due to negative cash flows from existing clients and client losses. Market appreciation of assets under management partially offset the decrease in earnings from LSV.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The increase in personnel costs was primarily due to business growth, primarily in the Investment Managers segment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Operating expenses increased primarily from higher costs for consulting and outsourced vendor costs supporting operations in the Investment Managers and Private Banks segments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capitalized software development costs were $22.8 million in the first nine months of 2025, of which $14.5 million was for continued enhancements to SWP. Capitalized software development costs also include $8.3 million of software development costs in the first nine months of 2025 for SEI Scope, a new platform for the Investment Managers segment placed into service during the third quarter 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amortization expense related to SWP was $21.6 million in the first nine months of 2025 as compared to $20.5 million in the first nine months of 2024. Amortization expense related to the SEI Scope platform was $1.1 million in the first nine months of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Effective tax rates were 21.9% during the third quarter 2025 and 23.5% during the third quarter 2024. During the first nine months of 2025 and 2024, effective tax rates were 22.3% and 23.4%, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• SEI repurchased 6.2 million shares of its common stock for $515.2 million in the first nine months of 2025.

*Stratos Wealth Holdings*

On July 17, 2025, we entered into an agreement with Stratos Wealth Holdings (Stratos), a family of companies focused on supporting the success of financial advisors across business models and affiliation structures. According to the agreement, we will pay a total cash consideration of approximately $527.0 million for 57.5% of the equity of Stratos. Certain legacy Stratos equity holders will continue to own 42.5%, which is subject to three equal put/call options at 36 months, 54 months and 72 months post-closing that, if fully exercised, will result in SEI owning 100.0% of Stratos. Subject to applicable regulatory approval and other customary closing conditions, the transaction is expected to close in two stages: the U.S.-based Stratos business, representing approximately 80.0% of the transaction value, and the Mexico-based NSC business. Professional fees and consulting costs incurred to date for the acquisition of Stratos have been recognized in corporate overhead. We expect to continue to incur these acquisition costs during the fourth quarter 2025.

---

Revenues decreased $7.4 million, or 48%, in the three month period and decreased $3.3 million, or 7%, in the nine month period ended September 30, 2025 and were primarily affected by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The divestiture of SEI Family Office Services during the second quarter 2025; partially offset by

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increased revenues from network and data protection services offered through SEI Sphere due to new business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Increased revenues from SEI Private Wealth Management through higher assets under advisement due to market appreciation and new business.

**<u>Other</u>**

*Corporate overhead expenses*

Corporate overhead expenses primarily consist of general and administrative expenses and other costs not directly attributable to a reportable business segment. Corporate overhead expenses were $42.8 million and $37.9 million in the three months ended September 30, 2025 and 2024, respectively, and $118.8 million and $109.0 million in the nine months ended September 30, 2025 and 2024, respectively. The increases in corporate overhead expenses is primarily due to increases in personnel costs, professional fees related to M&A activity, consulting and stock-based compensation costs and investments in upgrading and enhancing various technologies utilized by corporate overhead units. We expect professional fees from the expected acquisition of Stratos to continue into the fourth quarter 2025.

---

*Net gain from investments*

Net gain from investments in the three and nine months ended September 30, 2025 were primarily due to unrealized mark-to-market gains recorded in current earnings associated with LSV-sponsored investment funds and Company-sponsored investment funds from market appreciation (See Note 5 to the Consolidated Financial Statements).

*Interest and dividend income*

Interest and dividend income is earned based upon the amount of cash that is invested daily. The decrease in interest and dividend income in the three and nine months ended September 30, 2025 was due to an overall decline in interest rates and lower invested cash balances.

*Gain on sale of business*

We recognized a gain of $94.4 million during the second quarter 2025 from the divestiture of the Family Office Services business (See caption titled "Divestiture of Family Office Services Business" later in this discussion).

*Other income* 

We recognized a gain of $4.4 million from an insurance recovery during the third quarter 2025 and a gain of $4.5 million during the second quarter 2025 from the settlement of a matter with a third-party vendor.

*Equity in earnings of unconsolidated affiliate*

Equity in earnings of unconsolidated affiliate reflects our ownership interest in LSV. As of September 30, 2025, our total partnership interest in LSV was 38.5%. The table below presents the revenues and net income of LSV and the proportionate share in LSV's earnings.

| Revenues of LSV | $111750 | $122412 | (9)% | $325894 | $343581 | (5)% |
| Net income of LSV | 82812 | 94634 | (12)% | 244639 | 265335 | (8)% |
| SEI's proportionate share in earnings of LSV | $31903 | $36513 | (13)% | $94290 | $102375 | (8)% |

---

The decrease in earnings from LSV in the three and nine months ended September 30, 2025 was primarily due to lower assets under management from negative cash flows from existing clients and client losses. Market appreciation of client assets partially offset the decrease in earnings from LSV. Average assets under management by LSV decreased $1.5 billion to $90.1 billion during the nine months ended September 30, 2025 as compared to $91.6 billion during the nine months ended September 30, 2024, a decrease of 2%.

------

*Net gain from consolidated variable interest entities*

Net gain from consolidated variable interest entities in the three and nine months ended September 30, 2025 reflects the total net gains of the LSV Global Market Neutral Fund LP consolidated into our financial statements. The portion of this gain associated with our investment in the fund was $1.5 million during the three and nine months ended September 30, 2025. The portion of this gain associated with other investors in the fund is eliminated through income attributable to non-controlling interests in the accompanying Consolidated Statement of Operations (See Notes 1 and 15 to the Consolidated Financial Statements).

**<u>Amortization</u>**

Amortization expense on the accompanying Consolidated Statements of Operations consists of:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| | Three Months Ended September 30, | Three Months Ended September 30, | Percent Change | Nine Months Ended September 30, | Nine Months Ended September 30, | Percent Change |
| | 2025 | 2024 | Percent Change | 2025 | 2024 | Percent Change |
| Capitalized software development costs | $8405 | $7069 | 19% | $22800 | $20961 | 9% |
| Intangible assets acquired through acquisitions and asset purchases | 3168 | 3276 | (3)% | 9774 | 10066 | (3)% |
| Other | $339 | $68 | 399% | 497 | 257 | 93% |
| Total amortization expense | $11912 | $10413 | 14% | $33071 | $31284 | 6% |

---

*Capitalized software development costs*

The increase in amortization expense related to capitalized software development costs during the three and nine months ended September 30, 2025 was due to significant enhancements to SWP and the placement into service of SEI Scope during the third quarter 2025 (See Note 1 to the Consolidated Financial Statements).

**<u>Income Taxes</u>**

The effective income tax rates for the three and nine months ended September 30, 2025 and 2024 differ from the federal income tax statutory rate due to the following:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Three Months Ended September 30, | Three Months Ended September 30, | Nine Months Ended September 30, | Nine Months Ended September 30, |
| | 2025 | 2024 | 2025 | 2024 |
| Statutory rate | 21.0% | 21.0% | 21.0% | 21.0% |
| State taxes, net of federal tax benefit | 2.7 | 2.9 | 2.7 | 2.9 |
| Foreign tax expense and tax rate differential | (0.1) | 0.1 | (0.1) | 0.1 |
| Tax benefit from stock option exercises | (1.0) | (0.1) | (0.8) | (0.4) |
| Other, net | (0.7) | (0.4) | (0.5) | (0.2) |
|  | 21.9% | 23.5% | 22.3% | 23.4% |

---

The decrease in the effective tax rates for the three and nine months ended September 30, 2025 was primarily due to higher tax benefits related to stock option exercises and a decline in state effective tax rates.

On July 4, 2025, President Donald J. Trump signed new tax legislation known as the One Big Beautiful Bill Act (OBBBA) into law which makes permanent many of the provisions enacted in 2017 as part of the Tax Cuts and Jobs Act that were scheduled to expire at the end of 2025. The enactment of the OBBBA primarily impacted the deferred tax liability and income tax payable related to the provisions for the elimination of the capitalization of onshore research and development costs (Section 174) and the reintroduction of 100% bonus depreciation (Section 168) and did not have a significant impact to the effective tax rate.

**<u>Stock-Based Compensation</u>**

We recognized $42.0 million and $37.2 million in stock-based compensation expense during the nine months ended September 30, 2025 and 2024, respectively. The increase in expense was primarily due to new equity awards granted during the fourth quarter 2024. The amount of stock-based compensation expense recognized is primarily based upon management's estimate of when the financial vesting targets of outstanding stock options may be achieved. Any change in the estimate could result in the amount of stock-based compensation expense to be accelerated, spread out over a longer period, or reversed. This may cause volatility in the recognition of stock-based compensation expense in future periods and could materially affect earnings (See Note 7 to the Consolidated Financial Statements).

We expect to recognize approximately $11.8 million in stock-based compensation expense during the remainder of 2025.

------

**<u>Divestiture of Family Office Services Business</u>**

On February 27, 2025, we announced the entry into a definitive agreement with Aquiline, a private investment firm specializing in financial services and technology, to acquire our Family Office Services business. We completed the sale on June 30, 2025 and recognized a gain of $94.4 million, net of transaction costs and certain other purchase price adjustments, during the second quarter 2025. Prior to the divestiture, the Family Office Services business was reported in our Investments in New Businesses segment.

**<u>Regulatory Matters</u>**

Like many firms operating within the financial services industry, we are experiencing a complex and changing regulatory environment across our markets. Our current scale and reach as a provider to the financial services industry, the introduction and implementation of new solutions for our financial services industry clients, the increased regulatory oversight of the financial services industry generally, new laws and regulations affecting the financial services industry and ever-changing regulatory interpretations of existing laws and regulations, and a greater propensity of regulators to pursue enforcement actions and other sanctions against regulated entities, have made this an increasingly challenging and costly regulatory environment in which to operate.

SEI and some of our regulated subsidiaries have undergone or been scheduled to undergo a range of periodic or thematic reviews, examinations or investigations by numerous regulatory authorities around the world, including the Office of the Comptroller of the Currency, the Securities and Exchange Commission, the Financial Industry Regulatory Authority, the Financial Conduct Authority of the United Kingdom (FCA), the Central Bank of Ireland and others. These regulatory activities typically result in the identification of matters or practices to be addressed by us or our subsidiaries and, in certain circumstances, the regulatory authorities require remediation activities or pursue enforcement proceedings against us or our subsidiaries. From time to time, the regulators in different jurisdictions will elevate their level of scrutiny of our operations as our business expands or is deemed critical to the operations of the relevant financial markets. As described under the caption "Regulatory Considerations" in our Annual Report on Form 10-K, the range of possible sanctions that are available to regulatory authorities include limitations on our ability to engage in business for specified periods of time, the revocation of registration, censures and fines. The direct and indirect costs of responding to these regulatory activities and of complying with new or modified regulations, as well as the potential financial costs and potential reputational impact against us of any enforcement proceedings that might result, is uncertain but could have a material adverse impact on our operating results or financial position.

Our current credit facility provides for borrowings up to $500.0 million and is scheduled to expire in August 2030 (See Note 6 to the Consolidated Financial Statements). As of October 9, 2025, we had outstanding letters of credit of $4.9 million which reduced the amount available under the credit facility. These letters of credit were primarily issued for the expansion of the corporate headquarters and are due to expire in late 2025. As of October 9, 2025, the amount of the credit facility available for corporate purposes was $495.4 million.

The availability of the credit facility is subject to compliance with certain covenants set forth in the agreement. The credit facility contains covenants which restrict our ability to engage in transactions with affiliates other than wholly-owned subsidiaries or to incur liens or certain types of indebtedness as defined in the agreement. In the event of a default under the credit facility, we would also be restricted from paying dividends on, or repurchasing our common stock. Currently, our ability to borrow from the credit facility is not limited by any covenant of the agreement (See Note 6 to the Consolidated Financial Statements).

The majority of excess cash reserves are primarily placed in accounts located in the United States that invest entirely in commercial paper and SEI-sponsored money market mutual funds denominated in the U.S. dollar. We also utilize demand

------

deposit accounts or money market accounts at several large, well-established financial institutions located in the United States. The institutions we utilize have not indicated any stability issues regarding the ability to honor current or future deposit obligations to their customers. Accounts used to manage these excess cash reserves do not impose any restrictions or limitations that would prevent us from being able to access such cash amounts immediately. As of October 9, 2025, the amount of cash and cash equivalents considered free and immediately accessible for other general corporate purposes was $555.6 million.

Cash and cash equivalents include cash held in accounts of the LSV Global Equity Market Neutral Fund, LP consolidated into our financial statements and may only be used to settle obligations of the fund (See Note 15 to the Consolidated Financial Statements).

Cash and cash equivalents also include accounts managed by subsidiaries that are used in their operations or to cover specific business and regulatory requirements. The availability of this cash for other purposes beyond the operations of these subsidiaries may be limited. We therefore do not include accounts of foreign subsidiaries in the calculation of free and immediately accessible cash for other general corporate purposes. A portion of the undistributed earnings of foreign subsidiaries are deemed repatriated. Any subsequent transfer of available cash related to the repatriated earnings of foreign subsidiaries could significantly increase free and immediately accessible cash.

Cash flows from operations increased $54.2 million in the first nine months of 2025 compared to the first nine months of 2024 primarily from the increase in net income attributable to SEI. The negative impact from the change in working capital accounts due to decreased accrued liabilities, primarily from the higher payments of incentive compensation awards in 2025 as compared to 2024, partially offset the increase.

Net cash from investing activities includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Purchases, sales and maturities of marketable securities.* Purchases, sales and maturities of marketable securities in the first nine months of 2025 and 2024 were as follows:

---

| | | |
|:---|:---|:---|
| | Nine Months Ended September 30, | Nine Months Ended September 30, |
| | 2025 | 2024 |
| Purchases | $(123708) | $(134665) |
| Sales and maturities | 93367 | 121347 |
| Net investing activities from marketable securities | $(30341) | $(13318) |

---

See Note 5 to the Consolidated Financial Statements for more information related to marketable securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• The capitalization of costs incurred in developing computer software.* We capitalized $22.8 million of software development costs in the first nine months of 2025 as compared to $18.4 million in the first nine months of 2024. Software development costs are principally related to significant enhancements for the expanded functionality of the SEI Wealth Platform and a new platform for the Investment Managers segment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Capital expenditures.* Capital expenditures in the first nine months of 2025 were $21.1 million as compared to $27.2 million in the first nine months of 2024. Expenditures in 2025 and 2024 include capital outlays for purchased software and equipment for data center operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Proceeds from business divestiture.* We received gross proceeds of $116.0 million at the closing of the sale of the Family Office Services business on June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Other investing activities.* We made strategic investments of $3.5 million and $10.0 million during the first nine months of 2025 and 2024, respectively, in innovation platforms for wealth management.

Net cash from financing activities includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• The repurchase of common stock.* Our Board of Directors has authorized the repurchase of common stock through multiple authorizations. Currently, there is no expiration date for the common stock repurchase program. We had total capital outlays of $527.5 million during the first nine months of 2025 and $252.9 million during the first nine months of 2024 for the repurchase of common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Proceeds from the issuance of common stock.* We received $115.9 million and $62.8 million in proceeds from the issuance of common stock during the first nine months of 2025 and 2024, respectively, through our equity compensation plans. These proceeds were primarily from stock option exercise activity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Dividend payments.* Cash dividends paid were $123.3 million in the first nine months of 2025 as compared to $120.3 million in the first nine months of 2024.

------

**<u>Cash Requirements</u>**

Cash requirements and liquidity needs are primarily funded through cash flow from operations and our capacity for additional borrowing. At September 30, 2025, unused sources of liquidity consisted of cash and cash equivalents and the amount available under our credit facility.

We are obligated to make payments in connection with the credit facility, operating leases, maintenance contracts and other commitments. We believe our operating cash flow, available borrowing capacity, and existing cash and cash equivalents will provide adequate funds for these obligations and ongoing operations. We currently anticipate that our available funds and cash flow from operations will be sufficient to meet our operational cash needs, expected M&A activity, and fund our stock repurchase program for at least the next 12 months and for the foreseeable future.

We conduct operations through many regulated wholly-owned subsidiaries. These subsidiaries include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• SEI Investments Distribution Co., or SIDCO, a broker-dealer registered with the SEC under the Securities Exchange Act of 1934 and a member of the Financial Industry Regulatory Authority, Inc., or FINRA;

In addition to the regulatory authorities listed above, our subsidiaries are subject to the jurisdiction of regulatory authorities in other foreign countries. In addition to our wholly-owned subsidiaries, we also own a minority interest of approximately 38.5% in LSV, which is also an investment advisor registered with the SEC.

The Company, its regulated subsidiaries, their regulated services and solutions and their customers are all subject to extensive legislation, regulation, and supervision that recently has been subject to, and continues to experience, significant change and increased regulatory activity. These changes and regulatory activities could have a material adverse effect on us and our clients.

The various governmental agencies and self-regulatory authorities that regulate or supervise the Company and its subsidiaries have broad administrative powers. In the event of a failure to comply with laws, regulations, and requirements of these agencies and authorities, the possible business process changes required or sanctions that may be imposed include the suspension of individual employees, limitations on our ability to engage in business for specified periods of time, the revocation of applicable registration as a broker-dealer, investment advisor or other regulated entity, and, as the case may be, censures and fines. Additionally, certain securities and banking laws applicable to us and our subsidiaries provide for certain private rights of action that could give rise to civil litigation. Any litigation could have significant financial and non-financial consequences including monetary judgments and the requirement to take action or limit activities that could ultimately affect our business.

Governmental scrutiny from regulators, legislative bodies, and law enforcement agencies with respect to matters relating to our regulated subsidiaries and their activities, services and solutions, our business practices, our past actions and other matters has increased dramatically in the past several years. Responding to these examinations, investigations, actions, and lawsuits, regardless of the ultimate outcome of the proceeding, is time consuming and expensive and can divert the time and effort of our senior management from our business. Penalties, fines and changes to business processes sought by regulatory authorities have increased substantially over the last several years, and certain regulators have been more likely in recent years to commence enforcement actions or to advance or support legislation targeted at the financial services industry. We continue to be subject to inquiries from examinations and investigations by supervisory and enforcement divisions of regulatory authorities and expect this to continue in the future. We believe this is also the case with many of our regulated clients. Governmental scrutiny and legal and enforcement proceedings can also have a negative impact on our reputation, our relationship with clients and prospective clients, and on the morale and performance of our employees, which could adversely affect our businesses and results of operations.

We are subject to U.S. and foreign anti-money laundering and financial transparency laws that require implementation of regulations applicable to financial services companies, including standards for verifying client identification and monitoring client transactions and detecting and reporting suspicious activities. We offer investment and banking solutions that also are subject to regulation by the federal and state securities and banking authorities, as well as foreign regulatory authorities, where applicable. Existing or future regulations that affect these solutions could lead to a reduction in sales of these solutions or require modifications of these solutions.

We must comply with economic sanctions and embargo programs administered by the Office of Foreign Assets Control (OFAC) and similar national and multinational bodies and governmental agencies outside the United States, as well as anti-corruption and anti-money laundering laws and regulations throughout the world. We can incur higher costs and face greater compliance risks in structuring and operating our businesses to comply with these requirements. Furthermore, a violation of a sanction or embargo program or anti-corruption or anti-money laundering laws and regulations could subject us and our subsidiaries, and individual employees, to regulatory enforcement actions as well as significant civil and criminal penalties.

Our businesses are also subject to privacy and data protection information security legal requirements concerning the use and protection of certain personal information. These include those adopted pursuant to the Gramm-Leach-Bliley Act and the Fair and Accurate Credit Transactions Act of 2003 in the United States, the General Data Protection Regulation (GDPR) in the EU, Canada's Personal Information Protection and Electronic Documents Act, the Cayman Islands' Data Protection Law, and various other laws. Privacy and data security legislation is a priority issue in many states and localities in the United States, as well as foreign jurisdictions outside of the EU. For example, California enacted the California Consumer Privacy Act (CCPA) which broadly regulates the sale of the consumer information of California residents and grants California residents certain rights to, among other things, access and delete data about them in certain circumstances. Other states are considering similar proposals. Such attempts by the states to regulate have the potential to create a patchwork of differing and/or conflicting state regulations. Ensuring compliance under ever-evolving privacy legislation, such as GDPR and CCPA, is an ongoing commitment, which involves substantial costs.

Compliance with existing and future regulations and responding to and complying with recent increased regulatory activity affecting broker-dealers, investment advisors, investment companies, financial institutions, and their service providers could have a significant impact on us. We periodically undergo regulatory examinations and respond to regulatory

------

inquiries and document requests. In addition, recent and continuing legislative activity in the United States and in other jurisdictions (including the European Union and the United Kingdom) have made and continue to make extensive changes to the laws regulating financial services firms. As a result of these examinations, inquiries, and requests, as a result of increased civil litigation activity, and as a result of these new laws and regulations, we engage legal counsel and other subject matter experts, review our compliance procedures, solution and service offerings, and business operations, and make changes as we deem necessary or as may be required by the applicable authority. These additional activities and required changes may result in increased expense or may reduce revenues.

Our bank clients are subject to supervision by federal, state, and foreign banking and financial services authorities concerning the manner in which such clients purchase and receive our products and services. Our plan sponsor clients and our subsidiaries providing services to those clients are subject to supervision by the Department of Labor and compliance with employee benefit regulations. Investment advisor and broker-dealer clients are regulated by the SEC, state securities authorities, or FINRA. Existing or future regulations applicable to our clients may affect our clients' purchase of our products and services.

In addition, see the discussion of governmental regulations in Item 1A "Risk Factors" in our latest Annual Report on Form 10-K for a description of the risks that the current regulatory regimes and proposed regulatory changes may present for our business.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk.**

Information required by this item is set forth under the captions "Our revenues and earnings are affected by changes in capital markets and significant changes in the value of financial instruments" and "Changes in interest rates may affect the value of our fixed-income investment securities" in Item 1A Risk Factors and under the caption "Sensitivity of our revenues and earnings to capital market fluctuations" in Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes to this information as it is disclosed in our Annual Report on Form 10-K for 2024.

**Item 4. Controls and Procedures.**

(a) Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report are effective in ensuring that information required to be disclosed by us in reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the issuer's management including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. A controls system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the controls systems are met, and no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

(b) Change in Internal Control over Financial Reporting

No change in our internal control over financial reporting occurred during the quarter ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**PART II – OTHER INFORMATION**

**Item 1. Legal Proceedings.**

We and certain of our subsidiaries are a party to or have property subject to litigation and other proceedings, examinations and investigations that arise in the ordinary course of our business that we do not believe are material. These types of matters could result in fines, penalties, cost reimbursements or contributions, compensatory or treble damages or non-monetary sanctions or relief. We believe the probability is remote that the outcome of any of these matters will have a material adverse effect on SEI as a whole, notwithstanding that the unfavorable resolution of any matter may have a material effect on our net earnings in any particular interim reporting period. We cannot predict the outcome of legal or other proceedings with certainty. These matters include the proceedings summarized in "Note 11. Commitments and Contingencies" included in our Notes to Consolidated Financial Statements.

**Item 1A. Risk Factors.**

Information regarding risk factors appears in Part I – Item 1A of the Company's Annual Report on Form 10-K for the year ended December 31, 2024. There have been no material changes in the risk factors from those disclosed in the Annual Report on Form 10-K for 2024.

Currently, there is no expiration date for the common stock repurchase program. On October 20, 2025, our Board of Directors approved an increase in the stock repurchase program by an additional $650.0 million, increasing the available authorization to approximately $773.2 million.
