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 which are, in the opinion of management, necessary for a fair statement of financial position of the Company as of September 30, 2026, the results of operations for the three and nine months ended September 30, 2026 and 2025, and cash flows for the nine months ended September 30, 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 nine months ended September 30, 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 September 30, 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:

Redeemable Non-controlling Interests
Balance, December 31, 2025$243,959
Increase from acquisition10,400
Net income attributable to non-controlling interests7,348
Capital contributions from non-controlling interests, net758
Redemption value remeasurement60,640
Balance, September 30, 2026$323,105

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 $4,782 and $5,397 in fees during the three months ended September 30, 2026 and 2025, respectively. During the nine months ended September 30, 2026 and 2025, the Company waived $14,635 and $14,792, respectively, in fees.

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 Accounting Standards Codification (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.

Note 2 –Equity Method Investments

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

September 30, 2026December 31, 2025
Investment in LSV Asset Management$59,465$121,512
Other equity method investments34,80867,637
Total$94,273$189,149

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, 2026 was 38.4%. 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 September 30, 2026 and December 31, 2025, the Company’s total investment in LSV was $59,465 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 $117,726 and $104,768 in the nine months ended September 30, 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 $39,590 and $31,903 during the three months ended September 30, 2026 and 2025, respectively. During the nine months ended September 30, 2026 and 2025, the Company’s proportionate share in the earnings of LSV was $109,946 and $94,290, respectively.

This table contains condensed financial information of LSV:

Net income102,99582,812285,794244,639

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 2026 in connection with the Stratos Acquisition (See Note 12) and investments in non-affiliated limited partnership funds in which the Company holds a more than minor interest. At September 30, 2026 and December 31, 2025, the value of the equity method entities related to Stratos was $23,945 and $57,153, respectively. At September 30, 2026 and December 31, 2025, the value of the Company's investments in limited partnership funds was $10,863 and $10,484, respectively.

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, 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 September 30, 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 nine months ended September 30, 2026.

The fair value of the Company's investments in funds sponsored by LSV are 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.

Unrealized holding losses$(11,418)$(4,381)
Less: Income tax benefit2,6261,008
Unrealized holding losses, net of tax(8,792)(3,373)

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.

The unrealized 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:

Note 6 –Line of Credit

On August 18, 2025 (the Closing Date), the Company entered into afive-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 thefour 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 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, 2026. As of October 20, 2026, the Company had outstanding letters of credit of $4,630 under the Facility.

Stock-based compensation expense, net of tax$13,404$11,395$39,086$34,248

As of September 30, 2026, there was approximately $64,142 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 total intrinsic value of options exercised during the nine months ended September 30, 2026 was $87,923. The total options exercisable as of September 30, 2026 had an intrinsic value of $255,110. 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, 2026 and the weighted average exercise price of the options. The market value of the Company’s common stock as of September 30, 2026 was $102.66 as reported by the Nasdaq Stock Market, LLC.

Earnings per Share

The calculations of basic and diluted earnings per share for the three and nine months ended September 30, 2026 and 2025 are:

Basic earnings per common share$1.42$1.33$4.48$4.35
Diluted earnings per common share$1.38$1.30$4.37$4.25

During the three months ended September 30, 2026 and 2025, employee stock options to purchase 4,368,000 and 5,687,000 shares of common stock with an average exercise price of $75.30 and $66.09, respectively, were outstanding but not included in the computation of diluted earnings per common share. During the nine months ended September 30, 2026 and 2025, employee stock options to purchase 4,396,000 and 5,744,000 shares of common stock with an average exercise price of $75.28 and $66.04, 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.

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 5,890,000 shares at a total cost of $535,752 during the nine months ended September 30, 2026, 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. On October 20, 2026, the Company's Board of Directors approved an increase in the stock repurchase program by an additional $800,000. As of October 20, 2026, the Company had approximately $925,643 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

Note 10 –Income Taxes

The gross liability for unrecognized tax benefits at September 30, 2026 and December 31, 2025 was $15,415 and $13,613, respectively, exclusive of interest and penalties, of which $15,823 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 September 30, 2026 and December 31, 2025, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $2,420 and $1,685, respectively.

September 30, 2026December 31, 2025
Gross liability for unrecognized tax benefits, exclusive of interest and penalties$15,415$13,613
Interest and penalties on unrecognized benefits2,4201,685

Amount included in Current liabilities$4,057$3,642
Amount included in Other long-term liabilities13,77811,656
$17,835$15,298

The effective income tax rate for the three and nine months ended September 30, 2026 and 2025 differs from the federal income tax statutory rate due to the following:

Three Months Ended September 30,Nine Months Ended September 30,
2026202520262025
Statutory rate21.0%21.0%21.0%21.0%
State taxes, net of federal tax benefit2.82.72.82.7

Energy tax credits(0.7)—(0.7)—
Other, net(0.1)(0.7)0.1(0.5)
20.2%21.9%21.6%22.3%

The decrease in the effective tax rate for the three and nine months ended September 30, 2026 was primarily due to higher excess tax benefits recognized on employee stock option exercises and the favorable impact from the recognition of federal energy tax credits purchased during the period, both of which reduced the Company's income tax expense.

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.

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, 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 $13,500. 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 $13,500 of Rubicon client assets that Mr. Mason directed to be transferred to Orchard Park.

SEI Capital Accumulation Plan

As the Company reported in prior filings with the Commission, 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.

Defendants believe that they have valid defenses to plaintiffs’ claims and deny any wrongdoing. However, to avoid the costs and burdens of protracted litigation, after a private mediation the Company reached an agreement to resolve the Hall litigation as a class settlement. The terms of the resolution are not yet public, and the Hall plaintiffs must file a motion for preliminary approval on or before October 30, 2026. 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.

Following the delivery of the Skilled Person’s Phase 1 Report, SIEL agreed with the FCA that a variation of SIEL’s FCA permissions would apply from February 26, 2025 (the VREQ), such that SIEL needed the FCA’s prior consent to onboard new institutional clients where this would require a material change to its existing propositions, systems or services, or significant senior management engagement. SIEL also needed consent to launch any new proposition, product, or service that was not already offered by it at the time the VREQ came into effect.

Following a comprehensive program of change to address both the Skilled Person’s recommendations and the FCA’s underlying concerns, the FCA confirmed that the s.166 was closed on July 29, 2026.

On October 22, 2026, the FCA confirmed that it had lifted the VREQ with immediate effect, with the result that SIEL’s ability to onboard new institutional clients had been fully restored.

SIEL is no longer required to seek FCA permission for launching new products or solutions or new client engagements.

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 $22,520 at October 20, 2026 to limited partnership funds which are expected to be funded over time as capital calls are made in accordance with the applicable partnership agreements.

Unused Letters of Credit

As of September 30, 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 was designed to be completed by SEI-Eclipse in two stages. The first stage (the Stratos Acquisition) entailed 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 of the transaction (the Second Stage) was contemplated to be a purchase by SEI Eclipse 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) for approximately $103,000.

The Stratos Acquisition closed in December 2025. During the quarter, the Company and Stratos entered into an agreement to terminate the Second Stage and that released the Company from any and all obligations with respect to the consummation of the Second Stage (the Termination Agreement). The Company paid $32,500 to Stratos upon execution of the Termination Agreement. The Termination Agreement defines the conditions on which the Company may be required to make additional payments to Stratos if such conditions are satisfied within 60 months from the date of the Termination Agreement. Additionally, the Termination Agreement defines the conditions on which the Company may recover some or all of the initial payment of $32,500. The Company used an option pricing model to estimate the fair value of the payment provisions in the Termination Agreement. The fair value of the payment provisions was determined to be approximately equal to the $32,500 paid to Stratos upon execution of the Termination Agreement. It was also determined that any potential future additional payments or amounts potentially recoverable that were previously paid are immaterial as of September 30, 2026. As a result, the Company recognized a one-time charge of $32,500 during the third quarter 2026 resulting from the Termination Agreement which is reflected in Other (expense) income on the accompanying Consolidated Statements of Operations.

The acquisition consideration paid in consummating the Stratos Acquisition 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). Following consummation of the Stratos Acquisition, the Company indirectly owns a 57.5% controlling interest in SEI-Eclipse and certain Stratos equity holders own the remaining 42.5% of the common units of SEI-Eclipse through an aggregator entity (Stratos Aggregator). This 42.5% minority interest in 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, Business Combinations. The purchase price has been allocated to the tangible assets and identifiable intangible assets acquired and liabilities assumed, based upon their estimated fair values. In addition, the redeemable non-controlling interest was recorded at fair value under ASC 805. The Company finalized its accounting for the purchase price allocation related to the Stratos business during the third quarter 2026.

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.

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 following unaudited pro forma consolidated financial information reflects the results of operations of the Company for the nine months ended September 30, 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:

Revenues$1,925,843$1,725,408
Net income attributable to SEI Investments Company571,460450,173

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.

SWE Acquisition of Equity Method Investments (EMI Entities)

SWE used cash funded from the deposit account to purchase 100% interests ofnine entities and a majority interest intwo additional entities (collectively, the EMI Entities) through the exercise of its contractual rights noted above. The closing date on the additional interest acquired occurred at various dates during the first quarter of 2026. The following table summarizes the purchase consideration for the EMI Entities as of the various closing dates during the first quarter of 2026:

Purchase Consideration
Cash in deposit account$62,257
Promissory notes to sellers30,687
Fair value of previously held equity method investments40,323
Contingent consideration250
$133,517

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 estimated fair values of the assets acquired, liabilities assumed, and non-controlling interest for the EMI Entities as of the various closing dates:

EstimatedFair Value
Cash and cash equivalents$1,595
Other current assets23
Property and equipment, net16
Operating lease right-of-use asset654
Other assets450
Goodwill, net26,149
Identifiable intangible assets132,284
Lease liabilities(653)
Other liabilities(1,706)
Total net assets acquired$158,812
Non-controlling interest(25,295)
$133,517

The acquisitions of certain EMI Entities were accounted for as asset acquisitions andone transaction was accounted for as a business combination. For the business combination transaction, 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 goodwill 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 estimated fair value of the significant identifiable intangible assets:

EstimatedFair ValueEstimatedUseful Life
Trade names$1,3293 years
Unpatented technology8161 year
Client relationships126,76018 years
Non-compete agreements3,3796 years
Total identifiable intangible assets$132,284

The 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.

SWE Acquisition of Other Entities

After the first quarter 2026, SWE acquired other entities in addition to the EMI Entities. The Company accounted for these transactions in accordance with ASC 805. The total preliminary purchase consideration consisted of the following components:

Purchase Consideration
Cash$13,460
Promissory notes to sellers4,681
Total purchase consideration$18,141

The promissory notes have interest rates ranging from 4.00% to 5.00% and are payable in 8 to 16 quarterly installments ranging between January 30, 2028 and October 30, 2031.

The following table summarizes the preliminary estimated fair values of the assets acquired, liabilities assumed, and non-controlling interest for the other acquisitions:

The Company has identified client relationships as the only significant identifiable intangible asset. The following table summarizes the preliminary fair value of the significant identifiable intangible asset:

EstimatedFair ValueEstimatedUseful Life
Client relationships$11,16818 years

As a result, the amounts presented in the table above are preliminary. The Company anticipates it will finalize its accounting 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 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 $8,188 and $1,463 during the nine months ended September 30, 2026 and 2025, respectively, 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:
