## Letter from the Chairman .
![05_SEI_Guarino.jpg](seic-20260414_g4.jpg)

**Carl A. Guarino**

Chairman of the Board

Dear Stockholders,

As I step into the role of Chairman, I would like to thank Al West for his

57-year legacy as SEI's founder and Executive Chairman. We are grateful for

his lasting influence and are pleased that he will continue to support SEI as

Chairman Emeritus. Al's vision, values and commitment to innovation provide

a strong foundation for SEI's continued growth and evolution. I have been

impressed with how CEO Ryan Hicke and the leadership team at SEI have

built upon this legacy of entrepreneurism and transformation to drive

significant shareholder value over the past several years.

Our 2025 performance reflects the strength of this foundation and the

opportunities that lie ahead. SEI delivered another year of meaningful

progress marked by broad-based revenue and margin expansion, reflecting a

business that is positioned for sustainable long-term growth. These results

were driven by the leadership team's focused execution of strategy and the

commitment of our workforce to serving clients, strengthening our competitive

advantages and creating shareholder value.

I am proud of SEI's transformation towards our goal of a fully-integrated

enterprise. Our achievements in 2025 are early signs of the power of our

evolving horizontal operating model, which is central to our strategic

ambitions. 2025 showed us the benefit of better aligned talent, technology

and capital to pursue what we believe are the most compelling opportunities

in our markets. While we evolve our operating model, we will continue to

innovate in ways that deepen client relationships and enhance operational

leverage. We are focused on investing with purpose in talent, AI, technology

and capabilities to scale our advantages in outsourcing, advice and asset

management, while maintaining a prudent approach to capital allocation and

balance sheet management.

SEI has a clear strategic direction and a business model built to adapt and

scale. The Board remains enthusiastically engaged in overseeing execution,

capital allocation and risk management, and we are excited for SEI's next

phase of growth.

| **4** | **SEI** \| 2026 Proxy Statement  |

---

**Proxy statement.**

**This Proxy Statement is furnished in connection with the** 

**solicitation by the Board of Directors (the "Board") of SEI** 

**Investments Company ("SEI," "the Company," "we," or** 

**"our") of proxies for use at our 2026 Annual Meeting of** 

**Shareholders to be held on May 27, 2026, and at any** 

**adjournments thereof (our "2026 Annual Meeting").**

**2026 Annual meeting of** 

**shareholders**

Action will be taken at our 2026 Annual Meeting to elect three

directors with a term expiring at our 2029 Annual Meeting of

Shareholders; to approve on an advisory basis the compensation of

our named executive officers; to ratify the appointment of KPMG LLP

as independent registered public accountants to examine our

consolidated financial statements for 2026; and to consider such other

business as may properly come before our 2026 Annual Meeting and

any adjournments thereof. This Proxy Statement, the accompanying

proxy card or voting instruction form and our Annual Report for 2025

will be sent, or otherwise made available, to our shareholders on or

about April 15, 2026.

Our 2026 Annual Meeting will be held in a virtual-only format.

Shareholders will not be able to attend our 2026 Annual Meeting in

person. Shareholders may attend our 2026 Annual Meeting virtually

at **www.virtualshareholdermeeting.com/SEIC2026** by entering

the16-digit voting control number found on your proxy card or your

voting instruction form. Shareholders whose shares are held in the

name of a broker, bank or other nominee and who need their 16-digit

control number should contact their bank, broker or other nominee,

and to ensure receipt of the control number in a timely fashion, should

do so well in advance of the 2026 Annual Meeting of Shareholders.

**Voting at the meeting**

Only the holders of shares of our common stock, par value $.01 per

share ("Shares"), of record at the close of business on March 12,

2026 ("Shareholders"), are entitled to vote at our 2026 Annual

Meeting. On that date, there were 120,982,101 Shares outstanding

and entitled to be voted at our 2026 Annual Meeting. Each

Shareholder will have the right to one vote for each Share

outstanding in his or her name on our books.

See "Ownership of Shares" for information regarding the

ownership of Shares by our directors, nominees, officers, and

certain shareholders.

**Quorum and required votes**<br>A majority of the Shares entitled to vote at <br>the 2026 Annual Meeting, present either in <br>person or by proxy, will constitute a quorum <br>for all purposes of the 2026 Annual <br>Meeting. Shares voted on any matter <br>submitted to a vote at the Annual Meeting, <br>under Pennsylvania law, will be considered <br>present for all purposes of the meeting and <br>will therefore be counted for purposes of <br>calculating whether a quorum is present at <br>the Annual Meeting. Under Pennsylvania <br>law and our Articles and Bylaws, if a <br>quorum is present at the meeting:<br>•the three nominees for election as <br>directors will be elected to the Board if <br>the votes cast for each nominee exceed <br>the votes cast against the nominee;<br>•management's proposal to approve on <br>an advisory basis the compensation of <br>our named executive officers as <br>disclosed in this Proxy Statement will be <br>approved if the votes cast in favor of the <br>proposal constitute a majority of the <br>votes which all shareholders present in <br>person or by proxy are entitled to <br>cast; and<br>•the ratification of the appointment of our <br>independent public accountants will be <br>approved if the votes cast in favor of the <br>proposal constitute a majority of the <br>votes which all shareholders present in <br>person or by proxy are entitled to cast.<br>Abstentions are considered votes entitled to <br>be cast on a proposal, but not cast. <br>Therefore, abstentions will have no effect <br>on the election of directors, but will impact <br>the other proposals as they will have the <br>effect of a vote against the proposal. Broker <br>non-votes, which occur solely with respect <br>to "non-routine" matters such as the <br>election of directors or the advisory vote on <br>compensation, are considered not entitled <br>to be cast on those matters. Thus, <br>broker non-votes will have no effect on any <br>of the proposals.<br>

2026 Proxy Statement \| **SEI**<sub>5</sub>

**Proxy statement**<br>

**Other voting information**

Shares represented by each properly executed proxy card will be voted in the manner specified by the respective

Shareholder. If instructions to the contrary are not given, such Shares will be voted FOR the election to our Board of the

nominees listed herein; FOR management's proposal to approve on an advisory basis the compensation of our named

executive officers; and FOR the ratification of the appointment of KPMG LLP as independent registered public

accountants to examine our consolidated financial statements for 2026.

If any other matters are properly presented for action at the meeting, the proxy holders will vote the proxies (which confer

discretionary authority to vote on such matters) in accordance with their best judgment. Brokers or other nominees who

hold Shares for a beneficial owner have the discretion to vote on routine proposals when they have not received voting

instructions from the beneficial owner at least ten days prior to the Annual Meeting.

Your broker is not permitted to vote on your behalf on the election of directors or the advisory vote proposal on approval of

compensation, as well as any other non-routine matters unless you provide specific instructions by completing and

returning the proxy card or by following the instructions provided to you by your broker, trustee or nominee to vote your

Shares via telephone or the Internet. We expect that brokers and nominees will determine that they have the discretion to

vote the Shares held of record by them in the absence of voting instructions from the beneficial holder only on the

ratification of the selection of our independent public accountants.

As a result, it is important to understand that if you hold your Shares through a broker, you must give your broker specific

instructions on how to vote your Shares for them to be counted as votes cast on a number of matters considered at the

meeting and to affect the outcome of those votes.

You may vote your Shares in one of several ways, depending upon how you own your Shares. If you own shares

registered in the name of a bank, broker or other nominee, refer to your proxy card or voting instruction form to see which

voting methods are available to you. If you own shares that are registered with our transfer agent in your own name, you

may vote on the Internet, by telephone or mail as described on your ballot card or voting instruction form.

This year's annual meeting will be virtual. You may vote during the meeting pursuant to the rules and procedures for

participating in and voting during the Annual Meeting set forth in our meeting rules of conduct, which shareholders will be

able to view prior to or during the meeting at **www.virtualshareholdermeeting.com/SEIC2026** by entering the 16-digit

voting control number found on your proxy card or your voting instruction form, and by following the instructions to vote.

Any record Shareholder giving a proxy or other voting instruction has the right to revoke it by providing written notice of

revocation to our Secretary at any time before the proxy or voting instruction is voted.

**Please read both this Proxy Statement and our Annual Report before you cast your vote.**

|:---|:---|
| **Proposal**<br>**1**<br>| **Election of Directors.** |

---

**Board structure**

Our Board currently consists of eight members and is divided into three classes comprised of three directors in two of the

classes and two directors in the other class. One class is elected each year to hold office for a three-year term and until

successors of such class are duly elected and qualified, except in the event of death, resignation, or removal of a director.

At our 2026 Annual Meeting, Shareholders will be asked to vote upon the election of three nominees to the class of

directors whose term will expire at our 2029 Annual Meeting of Shareholders.

**Required vote and nomination process**

Under our Bylaws, directors must be elected by a majority of votes cast in uncontested elections. This means that the

number of votes cast "for" a director nominee must exceed the number of votes cast "against" the nominee. In contested

elections, the vote standard would be a plurality of votes cast. Our Bylaws provide that, in an uncontested election, each

director nominee who is an incumbent director must submit to the Board before the annual meeting a letter of resignation

that is conditioned on not receiving a majority of the votes cast at the annual meeting. Should a candidate not receive a

majority of the votes cast at the meeting, his or her resignation is tendered to the independent directors of the Board for a

determination of whether or not to accept the resignation. The Board's decision and the basis for the decision would be

disclosed within 90 days following the certification of the final vote results.

Shares represented by properly executed proxy cards in the accompanying form will be voted for such nominees in the

absence of instructions to the contrary.

The Board, following the recommendation of the Board's Nominating Committee and following the nominating process

described under the caption "Nominating Process" elsewhere in this Proxy Statement, has nominated Ryan P. Hicke,

Kathryn M. McCarthy and Thomas C. Naratil for election at our 2026 Annual Meeting. Each of the nominees are

incumbent directors, have consented to be named and to serve if elected, and have provided the Board the conditional

letter of resignation that is required under our Bylaws. We do not know of anything that would preclude these nominees

from serving if elected. If, for any reason, a nominee should become unable or unwilling to stand for election as a director,

either the Shares represented by all proxies authorizing votes for such nominee will be voted for the election of such other

person as our Board may recommend, or the number of directors to be elected at our 2026 Annual Meeting will be

reduced accordingly.

**Reasons for Board recommendation**

Set forth below is certain information concerning Mr. Hicke, Ms. McCarthy, Mr. Naratil and each of the five other current

directors whose terms continue after our 2026 Annual Meeting. In determining to nominate the nominees for election to

the Board, as well in considering the continued service of the other members of our Board, our Board has considered

**Corporate governance.**

Board leadership structure<br>

As of January 1, 2026, Mr. Guarino serves as the Chairman of our Board.

Alfred P. West, Jr., our founder and Chief Executive Officer until June 2022, served as our Executive Chairman of our

Board until his retirement from active participation as a Board member on December 31, 2025. Upon Mr. Guarino's

appointment as Chairman, Mr. West assumed the title of Chairman Emeritus, a position that establishes Mr. West as

an observer on our Board with no voting rights and a mentor and strategic sounding board to members of our

Executive Committee.

During Mr. West's tenure as Executive Chairman, Ms. McCarthy served in the capacity as Lead Independent Director with

the responsibilities and authority set out in the Lead Independent Director Charter. This position was designed to ensure

that the considerations of non-management directors are addressed at the Board. With the appointment of Mr. Guarino as

Chairman of the Board on January 1, 2026, this position was eliminated and the responsibilities of the Lead Independent

Director were consolidated in the Chairman position.

**Executive Sessions**

As the Lead Independent Director, Ms. McCarthy was responsible for chairing the executive sessions of the Board during

2025. Mr. Guarino, as Chairman, now discharges all such responsibilities. Our independent directors meet in regularly

scheduled executive sessions without management present.

**Director Independence** 

Our Board has determined that each of Mr. Brassington, Mr. Guarino, Ms. McCarthy, Mr. Naratil, Ms. Risi, and Mr. Romeo

is an "independent director" as such term is defined in Rule 5605(a)(2) promulgated by The NASDAQ Stock Market LLC.

In this Proxy Statement, these six directors are referred to individually as an "independent director" and collectively as the

"independent directors." In determining Mr. Naratil's independence, the Board took into account Mr. Naratil's directorship

with KKR Private Equity Conglomerate, LLC and the Company's commercial relationships with such entity and certain of

its affiliates, and determined that such relationships did not affect Mr. Naratil's independence.

Board committees<br>

The standing committees of our Board are the Audit Committee, the Compensation Committee, the Nominating

Committee, and the Legal and Regulatory Oversight Committee. Each committee operates pursuant to a formal written

charter, which are available on our website at **seic.com** under "Investor Relations > Leadership > Governance

Documents." The current composition, number of meetings, and primary responsibilities of each committee is set forth

below. The Board is currently finalizing an analysis of how best to support the strategic ambitions of the Company and

expects to enlarge the scope of responsibilities of its standing committees by amending the charters of these committees

to further delegate Board responsibilities as follows:

• The Compensation Committee will become the Compensation and Human Capital Committee and expand the

responsibilities of the current Compensation Committee to oversight, among other things, of matters related to CEO

and Executive Committee member succession planning, and executive talent and leadership development.

**Corporate governance**<br>

**Board and committee meetings** 

Our Board held fifteen meetings in 2025. During the year, each director attended more than 75 percent of the meetings of

our Board and of the committees on which he or she served, except for Mr. West. While we do not have a specific written

policy with regard to attendance of directors at our annual meetings of shareholders, we encourage, but do not mandate,

board member attendance at our annual meetings of shareholders, particularly with respect to board members who are up

for election at that annual meeting. All of our directors who were members of the Board at that time attended our 2025

Annual Meeting of Shareholders.

**Nominating process**

Our Nominating Committee consists solely of independent directors. Among the responsibilities of the Nominating

Committee is the management and administration of our Board Nomination and Shareholder Communication Policy.

Board candidates are considered by the Nominating Committee based on various criteria, such as their broad-based

business and professional skills and experiences, a global business and social perspective, concern for the long-term

interests of our shareholders, and personal integrity and judgment. Directors are also considered based on their diverse

backgrounds and on contributions that they can make to us, as well as their ability to fill a current board need. In addition,

directors must have time available to devote to activities of our Board and to enhance their knowledge of our industry. The

Board prefers a mix of background and experience among its members, and it uses its judgment to identify nominees

whose backgrounds, attributes and experiences, which taken as a whole, will contribute to insightful and robust, yet

collegial, Board deliberation. Accordingly, while there is no exact formula, we seek to attract and retain highly qualified

directors with relevant experience who have sufficient time to attend to their substantial duties and responsibilities to us.

Our Nominating Committee considers recommendations for nominations from a wide variety of sources, including

members of our Board, business contacts, our legal counsel, community leaders, and members of our management.

**<u>Shareholder nominations</u>**

Our Nominating Committee will also consider shareholder recommendations for director nominees that are received in a

timely manner. Subject to compliance with statutory or regulatory requirements, our Nominating Committee does not

expect that candidates recommended by shareholders will be evaluated in a different manner than other candidates. All

such recommendations for election of directors at the 2027 annual meeting should be submitted in writing to our Secretary

at our principal offices (1 Freedom Valley Drive, Oaks PA 19456-1100). The Nominating Committee Charter and the

Board's current policy with respect to Board Nominees and Shareholder Communications may be viewed on our website

at **seic.com** under "Investor Relations > Leadership > Governance Documents."

In addition, our shareholders may nominate candidates for election as director by soliciting votes using their own proxy

materials. See **[Other Important Information > Nominations and Proposals by Shareholders for our 2027](#if13c18c8b86c49198e3a6712ffe1ab44_2203)**

**[Annual Meeting](#if13c18c8b86c49198e3a6712ffe1ab44_2203)**.

**Board refreshment**

Our Board regularly reviews its composition, skills, and needs in the context of the Company's overall strategy. As a result

of this commitment to Board refreshment, we have added two highly-qualified independent directors in the past year,

strengthening our Board's expertise in traditional and emerging financial markets, digital technologies, customer

engagement, and organic and inorganic strategic growth.

**<u>No mandatory term limits</u>**

Our Board has concluded that directors should not be subject to mandatory term limits because the Board believes that

the knowledge, expertise and continuity provided by those directors who have experience with the Company and who

continue to meet the Board membership criteria considered by the Nominating Committee can continue to provide

valuable guidance to the Company.

**<u>Mandatory retirement age</u>**

To facilitate Board refreshment, at the recommendation of our Nominating Committee, our Board has adopted a retirement

policy, pursuant to which no director shall be nominated for re-election upon the conclusion of such director's term ending

after the director's 75th birthday, provided that the directors on the Board upon initial approval of the retirement policy are

not prohibited from serving as directors through the annual meeting of the Company's shareholders held in 2028.

**Enterprise risk management framework**

• We maintain an Enterprise Risk Management ("ERM") Policy and Program that reflects a structured, organization-wide

approach to risk identification, assessment, mitigation, and oversight. This program is administered throughout the year

by our Enterprise Risk Management team, leveraging standardized tools and defined governance processes to support

consistent and transparent risk management across the enterprise.

• Senior management from across our organization, including our subsidiaries, participate in the Enterprise Risk

Committee ("ERC"), which meets at least quarterly and more frequently when needed. The ERC oversees

enterprise-level risks, sets risk appetite for major risk categories, and provides governance and escalation channels for

significant risk issues.

• The ERC has established specialized advisory committees with focused expertise in order to ensure that the major

risk-producing activities by the Company receive focused attention and expertise, including the Technology Risk

Committee, Operational Risk Management Committee, and the Investment Management Risk Committee. These

committees are comprised of stakeholders with domain expertise from across the organization and subsidiaries.

They meet at least quarterly, or more often as circumstances warrant, to evaluate risks within their respective areas,

review the design and effectiveness of controls, oversee risk events and remediation activities, and escalate

matters to the ERC where appropriate.

• On an ongoing basis, risk identification and assessment activities are performed throughout the organization. This

includes risk assessments by our internal audit function, our compliance function, management-level committees, risk

practitioners, and subject-matter experts across technology, operations, investment management, and other business

areas, using standardized methodologies. These processes support consistent evaluation of inherent and residual risk,

inform mitigation strategies, and highlight issues requiring escalation or acceptance in line with established

governance thresholds.

• These assessments and insights reviewed with the ERC, which includes senior leaders from each of our major

business and supporting units. The ERC evaluates enterprise-level themes, material risks, and recommended

mitigation actions and ensures alignment with the organization's risk appetite and strategic objectives.

• Our Board, through its established governance structure, oversees executive management's risk management

processes, reviews Risk Appetite Statements for major risk categories, and receives escalations for significant risks in

accordance with committee charters and governance protocols.

• In January of each year, a key business risk summary is presented by our Chief Risk Officer to a joint meeting of the

Audit Committee and the Legal and Regulatory Oversight Committee of our Board. Additionally, this joint meeting of the

Audit Committee and the Legal and Regulatory Oversight Committee considers and approves the material corporate

policies related to matters overseen by our Risk function and Chief Risk Officer.

• During the year, our Chief Risk Officer, Chief Financial Officer, and our General Counsel have responsibility for

escalating, as appropriate, risk events and updates to the Audit Committee and the Legal and Regulatory Oversight

Committee, respectively.

**Corporate governance**<br>

Engagement with shareholders<br>

Our Board considers the feedback of our shareholders as critical to our long-term success and values the input provided

when making decisions for our Company. Our discussions with shareholders often relate to our executive compensation

program and governance matters.

During 2025, we performed an active shareholder outreach program, engaging investors to understand the issues that are

important to them so that management and the Board can use that knowledge to inform our decision-making and help

shape our corporate practices.

During 2025, we engaged with shareholders through one-on-one meetings, investor conferences, earnings calls, investor

and analyst calls, on site investor meetings, and bespoke investor roadshows. We also hosted an Investor Day in

September 2025, our first since 2022, where we provided a detailed overview of our business and strategy, which was

well received by participants. Our shareholder engagement team included our Chief Executive Officer, Chief Financial and

Chief Operating Officer, the heads of our business segments, and our Head of Investor Relations.

This engagement, together with our commitment to robust corporate governance, supported ongoing Board and

management oversight. During the year, we further strengthened Board oversight through the addition of two highly

qualified independent directors, Thomas C. Naratil and Karin A. Risi.

**Shareholder communications to our Board**

Shareholders may send communications to our Board in writing, addressed to the full Board, individual directors, or

a specific committee of our Board, in care of our Secretary, to our principal offices (1 Freedom Valley Drive, Oaks,

PA 19456-1100). Our Board relies on our Secretary to forward written questions or comments to the full Board, named

directors, or specific committees of our Board, as appropriate. General comments or inquiries from shareholders are

forwarded to the appropriate individual internally. The Board's current policy with respect to Board Nominees and

Shareholder Communications may be viewed on our website at **seic.com** under "Investor Relations > Leadership >

Governance Documents."

**Corporate governance**<br>

Other governance principles and practices<br>

The main governance documents of our Board include our Board Nomination and Shareholder Communication Policy, as

well as the charters of our Audit Committee, Compensation Committee, Nominating Committee, and Legal and Regulatory

Oversight Committee. Each of these documents and various other documents embodying our governance principles,

including our Code of Conduct (described below) are published on our website at **seic.com** under "Investor Relations >

Leadership > Governance Documents." As and when we amend the charters of any of these committees, we will update

the materials on our website and make the necessary filings with the SEC.

The Board has also adopted a number of other policies that directly affect governance and risk management. These

include the policies described below.

**<u>Code of conduct, code of ethics and related policies</u>**

We also maintain our Code of Conduct, our Whistleblowing, Complaints and Non-Retaliation Policy, and our Code of

Ethics for Senior Financial Officers. Amendments and waivers of our Code of Ethics for our Senior Financial Officers will

either be posted on our website or ﬁled with the Securities and Exchange Commission on a Current Report on Form 8-K.

**<u>Insider trading policy</u>**

We also have an Insider Trading Policy that governs transactions in our securities by our directors, officers, and

employees, and promotes compliance with the laws and rules applicable thereto. The Insider Trading Policy is filed as an

exhibit on our Annual Report on Form 10-K. The Insider Trading Policy provides that directors, executive officers, and

other employees subject to our insider trading compliance program are not permitted to enter into any transaction

designed to hedge, or having the effect of hedging, the economic risk of owning our securities.

**<u>Compensation-related policies</u>**

We have adopted a Compensation Recoupment Policy and a Stock Ownership Policy both of which are described below

under the caption "Compensation Discussion and Analysis."

**Related party transactions**

Our Board believes that transactions with related persons present a heightened risk of conflicts of interest (or the

perception thereof). Our Code of Conduct thus contains a provision regarding transactions with related persons that

requires that our Audit Committee review and approve, before it is consummated, any "related person" transaction as

defined in Item 404(a) of Regulation S-K to which a director or executive officer is, directly or indirectly, a party. A related

person transaction is any transaction that is anticipated would be reportable by us under Item 404(a) of Regulation S-K in

which we were or are to be a participant and the amount involved exceeds $120,000 and in which any related person had

or will have a direct or indirect material interest. No related person transaction will be executed without the approval or

ratification of our Audit Committee. It is our policy that directors interested in a related person transaction will recuse

themselves from any vote on a related person transaction in which they have an interest.

Since January 1, 2025, there have been no related person transactions with any director or executive officer of the

Company or any other related person, as defined in Rule 404 under Regulation S-K and none is proposed.

**Director compensation.**

During 2025, each director who was not an employee received an annual retainer of $70,000. The annual chair fee for the

Audit, Compensation, Legal and Regulatory Oversight and Nominating Committees was $20,000, $15,000, $15,000 and

$5,000, respectively, and the annual retainer fee for the Audit Committee was $10,000, for each of the Compensation and

Legal Regulatory and Oversight Committees was $7,500, and for the Nominating Committee was $5,000. The annual

retainer for the Lead Independent Director was $15,000, a position which no longer exists. Our Board expects to review

the foregoing retainers in light of any changes to the responsibilities of the various standing committees of the Board and

the Chairs thereof in connection with the currently ongoing governance review being undertaken by the Board.

Each non-employee director received an annual grant of 2,266 RSUs. RSUs granted in 2025 were time-based and not

based on the achievement of performance targets.

Our non-employee directors did not receive an annual grant of options during 2025. As of December 31, 2025, our

non-employee directors owned options to purchase the following aggregate numbers of Shares: Mr. Brassington, 25,500;

Our compensation philosophy is designed to align each executive's compensation with our short-term and long-term

performance and to provide the compensation and incentives needed to attract, motivate, and retain key executives who

are crucial to our long-term success. Shareholders are encouraged to read the CD&A and other sections of this proxy

statement regarding our compensation practices for named executive officers, which include discussions of the following:

• Members of the Compensation Committee of our Board are independent directors. The Compensation Committee has

established a thorough process for the review and approval of compensation program designs, practices, and amounts

awarded to our executive officers.

• The Compensation Committee engaged and received advice from a third-party compensation consultant concerning

the compensation of our Chief Executive Officer. It selected a peer group of companies, taking into account the

compensation consultant's recommendations, to compare to our Chief Executive Officer's compensation.

• We have many compensation practices that ensure consistent leadership, decision-making and actions without taking

inappropriate or unnecessary risks. The practices include:

• We have an incentive compensation repayment ("clawback") policy;

• We have a stock ownership policy requiring executives to maintain a minimum value of ownership of our equity in

accordance with the policy;

• With the exception of Mr. Hicke and Mr. Denham, as discussed in the CD&A, we employ our named executive officers

"at will" without severance agreements (other than participation in our Executive Severance and Change of Control

Plan) or employment contracts;

• We have a long-standing insider trading policy which, among other things, prevents executive officers from buying or

selling put or call options or futures on our Shares;

• Our performance-based incentive programs include a balance of different measures for short-term and long-term

programs; and

• Our executive officers' compensation amounts are aligned with our financial performance and the overall

implementation of our business strategies.

The Compensation Committee and the Board believe that these policies, procedures, and amounts are effective in

implementing our compensation philosophy and in achieving its goals. This advisory shareholder vote, commonly known

as "Say-on-Pay," gives you as a Shareholder the opportunity to approve or not approve our executive compensation

program and policies through the following resolution:

**"Resolved, that the holders of Shares of the Company approve, on an advisory basis, the compensation of the** 

**named executive officers, as disclosed in the Company's Proxy Statement for the 2026 Annual Meeting of** 

**Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission** 

**including the Compensation Discussion and Analysis, the 2025 Summary Compensation Table and the other** 

**related tables and disclosure."**

**Compensation discussion** 

**and analysis.**

The following compensation discussion and analysis contains statements regarding future individual and Company

performance measures, targets and other goals. These goals are disclosed in the limited context of our executive

compensation program and should not be understood to be statements of management's expectations or estimates of

results or other guidance. We specifically caution investors not to apply these statements to other contexts.

Our compensation philosophy<br>

Our compensation philosophy (which is intended to apply to all members of management, including Principal Executive

Officer ("PEO") who is our Chief Executive Officer), as implemented by the Compensation Committee of our Board (the

"Committee"), is to provide a compensation program that provides competitive levels of compensation and that

emphasizes incentive compensation plans and equity plans that are designed to align management incentives and

behavior with attaining our annual goals and longer-term objectives. We believe that this approach enables us to attract,

retain and reward highly qualified personnel and furthers our tactical and strategic goals. The Committee seeks to develop

a compensation program that, overall, the Committee believes is competitive with compensation paid to employees with

comparable qualifications, experience and responsibilities at companies of comparable size engaged in the same or

similar businesses as us. The Committee does not explicitly pay any position at a specific level or mix with reference to

any particular group.

Our compensation program<br>

The compensation program for almost all of our non-sales, full-time employees (in addition to benefits afforded to all

employees, such as health care insurance and stock purchase and defined contribution plans) consists of:

• base salary; and

• incentive compensation awards pursuant to a corporate incentive compensation plan.

Equity compensation for selected, higher-level employees is provided by annual grants of stock options and restricted

stock units ("RSUs").

The Committee has sought to keep base salaries at a relatively modest portion of total compensation for higher

compensated employees, so that the overall compensation program is more heavily weighted toward incentive

compensation in the form of annual cash bonuses and sales commissions, and for selected high-performing employees:

• stock option grants that have performance vesting requirements based on attainment of adjusted pre-tax earnings per

share ("EPS") targets as well as minimum time vesting periods;

• annual RSU grants made in December 2025 and going forward vest over three years in equal annual installments,

provided that the grantee is an employee in good standing on each vesting date.

Consistent with our pay for performance philosophy, during 2025 approximately 93% of our current PEO's pay and

approximately 83% of the compensation of our other named executive officers ("NEOs") was paid in the form of variable

performance-based compensation, such as incentive compensation or stock options and RSUs (see "Summary

Compensation Table").

Alignment with shareholder interests<br>

The Committee has sought to include a number of features in the compensation program that are designed to align the

interests of management with the interests of shareholders. These features include:

• a mixture of elements that we believe will enable us to recruit and retain talented employees;

• orientating the cash compensation program elements toward incentive compensation for those employees who are in

roles that we believe are critical to our long-term growth prospects;

• the use of EPS targets as vesting requirements for stock option grants in order to incent a growth mindset in

our employees;

• time vesting for our RSU grants in order to create a longer-term view of the value of a tenured career;

• our Stock Ownership Policy (requiring minimum threshold shareholdings by our senior executive officers);

• our Executive Severance and Change of Control Plan for our senior executive officers;

• our Compensation Recoupment Policy (which provides for claw-back of performance-based compensation in certain

instances); and

• our Insider Trading Policy (which prohibits short sales, transactions in derivatives of our stock, and

hedging transactions).

Consideration of last year's say on pay vote<br>

At our 2025 Annual Shareholders' Meeting, our shareholders expressed support for the compensation of our named

executive officers disclosed in our 2025 Proxy Statement, with 88.4% of the votes cast voting in favor of the "Say-on-Pay"

proposal. When setting compensation, and in determining our compensation policies and practices, the Committee took

into account the results of the 2025 "Say-on-Pay" advisory resolution to approve such executive compensation as

demonstrating support of our compensation programs.

2025 Elements of compensation<br>

**Base salary and incentive compensation targets**

The Committee seeks to recommend base salaries for management employees at levels that it believes are sufficiently

competitive with salaries paid to management with comparable qualifications, experience and responsibilities at

companies of comparable size, operational complexity and businesses to us.

Incentive compensation consists of two components: annual bonuses and sales commissions. Sales commissions are

based on sales events and are measured on the basis of asset accumulation, asset retention, or anticipated revenue from

contracted sales, generally taking into account related factors, such as expected profit margins. Executive officers

participate only in the annual bonus program and do not participate in sales commission plans.

Annual bonuses are determined through a process overseen by the Board and the Committee. Each individual who

participates in the plan is assigned a target compensation award which may change from year to year, but generally is the

same as that individual's prior year target amount. In the case of executive officers, the target amount is generally

between 154% and 235% of the officer's base salary, reﬂecting the determination of the Committee to emphasize

performance-based incentive compensation over fixed compensation.

The Committee's process for allocating incentive compensation as follows:

• determining the aggregate amount of all individual target compensation awards for that year as input into establishing

an overall incentive pool that may be paid out if an EPS target is achieved; and

• early in the year in question, identifying:

• key business metrics, the Company's sales and a range of EPS (the "Quantitative Performance Metrics"); and

• indices of success against executing on management-defined strategic and tactical objectives for the Company as a

whole and individual market and business units (the "Qualitative Performance Metrics"),

in each case, for the year that may be considered in determining what percentage of that overall pool will be paid in the

particular year;

• near the end of the particular year, based on the Quantitative and Qualitative Performance Metrics (together, the

"Performance Metrics"), the Committee establishes the overall maximum incentive compensation pool for that year;

• the Committee then apportions the resulting overall actual incentive compensation pool among the market and

business units based on the Committee's subjective assessment of the degree to which each unit contributed to our

overall success in each of the Performance Metrics for that year; and

• the management teams of each of our market and business units takes the aggregate amount of incentive

compensation allocated to the unit by the Committee and awards individual bonuses to employees within those units

based upon such management's assessment of each individual's contribution to the achievements of those units, as

well as each individual's personal achievements.

The Committee's assessment is performed for two different pools:

• each of our executive officers individually; and

• all employees other than executive officers, as a group.

When the Committee evaluates business units and executive officers for the purpose of making compensation decisions,

it meets with our PEO and reviews a number of factors including:

• our PEO's evaluation of the units and each of the individual executive officers;

• the Performance Metrics established at the beginning of each year to provide a basis for assessment of performance

for these units and those executive officers who are primarily responsible for the performance of such units;

• performance against the prior year's actual Performance Metrics and other annual goals that are considered within the

overall business environment of that year;

---

| | |
|:---|:---|
| 2026 Proxy Statement \| **SEI** | **31** |

---

**Compensation discussion and analysis**<br>

• achievement of strategic and operating results; and

• in the case of the individual executive officers:

• their success in their management responsibilities generally;

• achievement of strategic and tactical goals of the market or business unit for which they are responsible;

• achievement of any personal strategic or tactical goals that may have been established for the individual

employee; and

• the degree to which the individual employee supported or contributed to, our overall corporate success.

When the Committee makes decisions regarding equity or non-equity incentive compensation, it exercises independent

business judgment. There is no specific formula the Committee applies when considering the factors that the Committee

believes are important to the assessment of any of our market or business units' performance or that of any individual

executive officer or our PEO, nor does the Committee attach any specific weighting or priority to the factors it considers.

Consequently, there is no direct correlation between any particular performance measure considered by or reported to the

Committee and the resulting equity or non-equity incentive compensation awards. The Committee believes that

compensation decisions should not be formulaic, rigid or focused on the short-term.

**2025 Maximum Bonus Pool**

For 2025, the Board and the Committee chose to fix the maximum aggregate amount for the non-equity incentive

compensation award pool (the "Maximum Bonus Pool") for each of our business units and corporate services functions as

a percentage of total target non-equity incentive compensation for those employees in such business units and corporate

services functions. Upon the recommendation of executive management, the Committee determined that a percentage of

94% would apply to all of our business units and corporate services functions other than our IMS and Private Banking

units, the percentages for which would be 110% and 97.5%, respectively. As in the past, the Committee recognized that

with the managers of such units would allocate these pools among the individual employees reporting to them as they

believed was appropriate. In total, the aggregate non-equity incentive awards paid to employees other than our executive

officers was 98% of the total amount of 2025 target incentive compensation amounts. Executive management made the

foregoing recommendations that differentiated the percentages payable to our IMS and Private Banking units because the

financial performance and related contribution to our EPS of these units was demonstrably better than that of our

other units.

**2025 Annual incentive compensation awards for executive officers**

For all executive officers eligible for incentive compensation as of December 2025, the Committee determined that the

non-equity incentive compensation awards made to all executive officers ranged from 100% to 110% of their

respective 2025 incentive compensation target amounts. The aggregate amount of non-equity incentive compensation

awarded to our named executive officers set forth the "Summary Compensation Table" was approximately 111% of the

aggregate non-equity incentive compensation awards made to our executive officers in 2024.

The Committee made these decisions at its December 2025 meeting where it considered and discussed, among

other things:

• our PEO's views on the 2025 performance of the senior executives (other than himself), their market or business units,

their tenure with the Company requiring proration of target amounts, as well as his recommendations for non-equity

incentive compensation awards and stock option grants or restricted stock units for the senior executives and

their units;

• the Performance Metrics;

• the Company's incentive compensation philosophy as described in the Proxy Statement for the 2025 Annual Meeting

of Shareholders;

• input from the Consultant on general industry trends in incentive compensation for fintech companies and asset

management companies;

• the business metrics disclosed in the "Pay Versus Performance" section of this Proxy Statement;

• the projected annual gross sales events and revenue of the Company's business units;

**Compensation discussion and analysis**<br>

• the $5.63 diluted earnings per share of the Company, which is a 28% increase from 2024;

• the growth initiatives launched during the year;

• our long-term strategic objectives for our executive officers and their respective business units;

• the desire of the Committee to align incentive compensation awards to long-term shareholder value creation;

• the approximately $740.4 million returned to our shareholders via dividends and stock repurchases;

• our progress towards achieving overall long-term strategic goals;

• each executive officer's market or business unit's:

• performance against its sales goals;

• contributions to corporate earnings;

• revenues and profit margins; and

• success in meeting various strategic and tactical goals of the unit; and

• the individual performance and achievements of each of the executive officers.

The Committee also independently reviewed the performance of the PEO with primary consideration to our overall

performance, as well as his individual performance on strategic and non-ﬁnancial achievements and discussed and

approved his annual non-equity incentive compensation award.

Equity grants<br>

Our annual equity grants consist of stock options and RSUs. The Committee believes these grants are an important

means of aligning the interests of management and employees with the interests of our shareholders. All of our

outstanding stock options have performance-based vesting provisions:

• those year-end stock options granted in December 2025 vest on the later of (a) the second anniversary of the date of

the grant, and (b) the date on which the Company achieves adjusted earnings per share (calculated as the quotient of

(x) the Company's calendar year income before income taxes (as set forth in the Company's Form 10-K as filed with

the Securities and Exchange Commission in the relevant year) adjusted (i) to not include (1) any reduction for ASC 718

(Accounting for Share-Based Compensation related to stock options only), and (2) the amount attributable to the gain

on the Company's sale of its Family Office Services business, and (ii) further adjusted to exclude <u>the product of</u> (X) any

amount of the Company's consolidated income that is attributable to any consolidated entity in accordance with ASC

810 (Consolidation) that is a less than wholly-owned entity, multiplied by (Y) the percentage of non-controlling equity of

any such entity that is a less than wholly-owned entity, <u>divided by</u> (y) the Company's diluted shares then outstanding)

that is equal to or greater than an amount that is 25% or more than the Company's adjusted earnings per share

(calculated in the same manner as in the previous clause (x)) as of the end of the year in which the grant was

made; and

• those stock options granted prior to 2024 vest at a rate of 50 percent when a specified pre-tax earnings-per-share

target is achieved, and the remaining 50 percent when a second, higher specified pre-tax earnings-per-share target

is achieved.

Prior to 2017, there was no minimum time-based factor in the vesting of our stock options. Beginning in 2017, the

Committee changed the vesting thresholds from an earnings per share target to a pre-tax earnings per share target, and it

also implemented minimum time periods for vesting. In 2022, the Committee introduced RSUs as an element of annual

equity compensation awards.

Our annual RSU awards granted prior to December 2025 generally "cliff vest" on the third anniversary of the date of the

grant. After considering the input of our Compensation Consultant, the practices of our competitors, the compensation

packages being offered to our employees by other enterprises and the need to attract, incent and retain highly

sophisticated and knowledgeable employees in order to support and execute against our strategic ambitions, the

Committee reviewed the construct of our equity award grants and determined that it would be in the best interests of the

Company to change the vesting of our annual RSU grants from three-year "cliff vesting" to awards that vest annually over

three years. Consequently, the annual RSU awards granted in December 2025 vest, and annual RSU awards in

subsequent years will vest, over three years in equal annual installments, provided that the grantee is an employee in

good standing on each vesting date. Other than in the case of executive officers, the annual grants of options and RSUs

to employees is standardized across the Company and based upon a tier system with the mix of the options and RSUs in

favor of options in the higher tiers.

Annual equity awards are generally determined by the Committee in December of each year. Our PEO reviews with the

Committee the grants for each executive officer, other than himself, as well as the grants for the other employees. The

Committee then deliberates and establishes the specific option grants and ﬁnally submits these option grant amounts to

the entire Board for ratification.

**2025 Equity awards**

Based on management feedback and the input of our Compensation Consultant, the Committee determined that in 2025

that there would continue to be four tiers of grants for non-executive employees, with individual executive officers and

Board members being considered on a case-by-case basis, and the participants in each of the tiers would receive options

and RSUs as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Grant type** | **Tier 1A** | **Tier 1B** | **Tier 2** | **Tier 3** |
| Options | 7,300 | 4,200 | 2,000 |  |
| RSUs | 825 | 550 | 375 | 325 |

| 2026 Proxy Statement \| **SEI** | **35** |

**Compensation discussion and analysis**<br>

The Committee reaffirmed its 2022 decision to re-evaluate in connection with each annual award cycle the composition of

each tier with some employees who had previously participated being removed from the program, with a particular focus

on those employees in the lowest tier.

At its December 2025 meeting, the Committee considered the annual grant of equity awards to each of our named

executive officers. The Committee reaffirmed its belief that option grants with performance-based vesting targets were a

very effective way to align the interests of the executives with the interests of shareholders. In addition to the factors

enumerated above in "2025 Annual Incentive Compensation Payouts," the Committee considered impact that it believed

the role the executive holds should have on the growth prospects of the Company and Mr. Hicke's recommendations as to

a more standardized approach to granting equity awards to executive officers based on his view of the expected

contributions of different groups of executive officers to our growth.

**2025 Equity grants to named executive officers**

In December 2025, the Committee awarded options and RSUs to our named executive officers as set forth in the table

below. The options and RSUs awarded to each individual in December 2024 is also provided for comparative purposes:

| **Philip N. McCabe** | 47000 | 8434 | 36000 | 7000 |

---

<sup>(1)</sup> Mr. Denham received a year-end grant of 22,500 options and 15,000 RSUs in December 2024 as per the terms of Mr. Denham's

previously disclosed employment agreement.

<sup>(2)</sup> The 2025 year end RSU amount includes a one-time grant of 7,500 RSUs in recognition of Mr. Sharma's new role as CEO of

SEI International.

The number of options and RSUs granted at the December 2025 meeting to our named executive officers was

approximately 187% and 131%, respectively, of the number granted to such officers in December 2024.

In 2025, the total number of options and RSU grants the Committee approved as part of the year-end annual grant

process was 1.4 million options to 240 employees and 269 thousand RSUs to 457 employees as compared to 2024 when

the total number of options approved and RSU grants the Committee approved as part of the year-end annual grant

process was 1.3 million options to 259 employees and 305 thousand RSUs to 518 employees.

During 2025, we repurchased in open market or private transactions approximately 7.5 million Shares under our stock

repurchase program at a total cost of approximately $616.2 million, compared to 6.8 million Shares under our stock

repurchase program at a total cost of approximately $512.5 million in 2024. These share repurchase activities

substantially offset the dilution which can result from grants and exercises under our equity compensation programs.

2025 Compensation changes<br>

The Committee reviewed the contributions of each of the executive officers during 2025, the contributions expected in the

future, and the competitive landscape for highly-skilled, similarly situated individuals in connection with determining

whether to adjust salaries and non-equity incentive compensation targets for 2026. After such review, it was determined

that each of the following named executive officers should receive a $50,000 salary increase: Mr. Hicke, Mr. McCabe and

Mr. Sharma. Each of Mr. Denham and Mr. Lane's salaries remain unchanged from 2024. Further, each of our named

executive officers, with the exception of Mr. Lane, received an increase in his 2026 target incentive compensation amount.

**Compensation discussion and analysis**<br>

Compensation-setting process<br>

Since 2012, the Committee has retained Semler Brossy Consulting Group, LLC ("Semler Brossy" or "Consultant") as its

executive compensation consultant when structuring compensation plans or engaging in comparative compensation

analyses. The Committee continued its annual engagement activities with the Consultant during 2025 and retained the

Consultant on an advisory capacity with respect to industry trends (See "Compensation Consultant" below.)

**Compensation consultant**

During 2025, the Committee re-engaged Semler Brossy to provide advice with respect to:

• general industry trends for executive compensation in the asset management and fintech sectors; and

• evaluating the components of our equity compensation plan, including the vesting hurdles of our equity

compensation plan.

Semler Brossy provides no other services to us outside of its role as independent Committee advisor.

Because of the policies and procedures Semler Brossy and the Committee have in place, the Committee is confident that

the advice it receives from the executive compensation consultant is objective. These policies and procedures include the

following provisions:

• the Committee has the sole authority to retain and terminate the executive compensation consultant;

• the Consultant has direct access to the Committee without management intervention;

• the Committee's evaluation of the quality and objectivity of the services provided by the Consultant each year in

connection with retaining the Consultant; and

• the protocols for the engagement (described below) limit how the Consultant may interact with management.

While it is necessary for the Consultant to interact with management to gather information, the Committee has adopted

protocols governing if and when the Consultant's advice and recommendations can be shared with management. These

protocols are included in the Consultant's engagement letter. The Committee also determines the appropriate forum

for receiving Consultant recommendations. Where appropriate, management invitees are present to provide context for

the recommendations. This approach protects the Committee's ability to receive objective advice from the Consultant so

that the Committee may make independent decisions about our executive compensation. The Consultant reports directly

to the Committee and performs no other work for the Company. The Committee has analyzed whether the work of Semler

Brossy as a compensation consultant has raised any conflict of interest, taking into consideration the following factors:

• The provision of other services to us by Semler Brossy;

• The amount of fees paid by us to Semler Brossy as a percentage of the firm's total revenue;

• Semler Brossy's policies and procedures that are designed to prevent conflicts of interest;

• Any business or personal relationship of Semler Brossy or the individual compensation advisors employed by the firm

with any of our executive officers;

• Any business or personal relationship of the individual compensation advisors with any member of the Committee; and

• Any of our Shares owned by Semler Brossy or the individual compensation advisors employed by the firm.

The Committee has determined, based on its analysis of the above factors, that the work of Semler Brossy and the

individual compensation advisors employed by Semler Brossy as our compensation consultants has not created any

conflict of interest.

**Compensation discussion and analysis**<br>

**Peer group**

When evaluating the compensation practices at "peer group" companies for comparative purposes, the Committee used

the same cohort of companies as was used as reference points in the Compensation Analysis Project described in the

Proxy Statement we filed with the Securities and Exchange Commission in connection with our 2024 Annual Meeting of

Shareholders. Due to the recency of this project, the Committee did not believe that it was necessary to re-evaluate the

composition of the "peer group."

In its deliberations regarding compensation, the Committee considered the annual analysis of fintech and asset

management industry compensation trends undertaken for the Committee by the Consultant.

**Review of compensation practices**

During 2025, the Committee continued to review our compensation practices and the elements of our equity

compensation program. The Committee worked with our Compensation Consultant throughout this process. Additionally,

the Committee reviewed vesting terms with respect to stock option grants as well as RSUs to ensure the Company

remains consistent with industry benchmarks and that continue to be valued by employees. As a consequence, the

Committee recommended to our Board, and the Board approved:

• changes to the standard vesting requirements for stock options granted to employees such that they vest on the later of

(a) the second anniversary of the date of the grant, and (b) the date on which the Company achieves adjusted earnings

per share (calculated as the quotient of (x) the Company's calendar year income before income taxes (as set forth in

the Company's Form 10-K as filed with the Securities and Exchange Commission in the relevant year) adjusted to

Other compensation matters<br>

**Stock ownership policy**

Under our Stock Ownership Policy, directors and executive officers are required to own equity interests in the Company

having a required value which is a multiple of their base compensation. The equity value may consist of the ownership of

Shares of Common Stock or of vested and exercisable stock options (valued at the amount by which the market price of

the underlying shares exceeds the exercise price of the option), provided that at least 50 percent of the required value is

in the form of direct ownership of our Shares of Common Stock. The required value is equal to five times their annual cash

retainer in the case of directors, six times his annual base salary in the case of the Chief Executive Officer, and four times

their annual base salary in the case of other executive officers. The Policy provides that the required value must have

been achieved for existing directors and executive officers in March of every year, and for persons elected as directors or

appointed or promoted as officers after the adoption of the Policy, not later than the fifth anniversary of such election or

appointment. All of directors and executive officers are in compliance with this Policy.

**Compensation discussion and analysis**<br>

**Equity grant practices**

We have no practice or policy of coordinating or timing the release of the Company information around the grant dates of

options or other equity awards, and we have not timed the disclosure of material non-public information for the purposes

of affecting the value of executive compensation. On occasion, we grant equity awards outside of our annual grant cycle

for new hires, promotions, recognition, retention or other purposes. These "off cycle" awards are granted only on a

limited basis and may vest 100% on the third anniversary of the grant, in equal tranches over a three-year period, or

such other conditions as the Committee believes is appropriate given the individual situation and intended purpose of

the award.

**Compensation risk assessment** 

The Committee has also reviewed our compensation policies as generally applicable to all of our employees and believes

that our policies, taking into account the mitigation policies and arrangements in place, do not encourage excessive or

unnecessary risk-taking and that any level of risk they do encourage is not reasonably likely to have a material adverse

effect on us.

**Compensation recoupment policy**

Our Compensation Recoupment Policy aligns with listing rules adopted by the NASDAQ Stock Market LLC as required by

the Securities and Exchange Commission. The policy applies to all executive officers (as defined under the applicable

rules), as well as certain other members of our senior management committee, and requires us to seek to recoup certain

incentive-based compensation, whether cash- or equity-based, from current or former officers in the event that we are

required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement

under the securities laws.

**Potential payments on termination**

We have various arrangements with our executive officers with respect to certain payments and benefits in the event the

executive officer is subject to a termination. Such arrangements are described below in the Potential payments upon

termination section in the Executive Compensation section of this Proxy Statement.

**Executive compensation**<br>

Employment arrangements of our named <br>executive officers<br>

We entered into an employment agreement with Mr. Hicke on March 31, 2022, when he was appointed to serve as our

Chief Executive Officer beginning on June 1, 2022. His compensation in 2025 was determined in accordance with that

employment agreement, which had a term from June 1, 2022 through June 1, 2026. As previously disclosed, on

January 13, 2026 we entered into a new agreement with Mr. Hicke with a term ending on June 1, 2031, which replaced

his former agreement. This section describes the terms of the new agreement. Under his current agreement, Mr. Hicke will

receive (i) an annual salary of $900,000 (which may be increased, but not decreased, during the term of the agreement)

and (ii) an annual target bonus opportunity of $2,700,000, commencing in fiscal year 2026, based on individual and/or

Company performance as determined by our Compensation Committee, which annual target amount may be increased at

the discretion of the Compensation Committee during the term of the agreement. The agreement also provides that for

each year during the term of the agreement, Mr. Hicke will be eligible to receive an annual equity grant in such form and

on such terms as the Board or Compensation Committee deems appropriate. Pursuant to the agreement, Mr. Hicke will

receive the following severance benefits if his employment is terminated by the Company other than for Cause (as defined

in the agreement), death or disability and he executes and does not revoke a general release of claims: (i) the accrued

obligations as defined in the agreement; (ii) an amount equal to (x) one and one-half times his base salary as of the

termination date and (y) one and one-half times his annual bonus for the year of termination, payable in payroll

installments during the 18-month period following the year of termination; and (iii) accelerated full vesting of any then

outstanding unvested equity awards. If Mr. Hicke's employment is terminated as a result of his death or disability, he will

receive (i) the accrued obligations and (ii) accelerated full vesting of any then outstanding unvested equity awards.

Mr. Hicke will be subject to covenants not to compete with the Company or solicit its employees or customers during his

employment and for a period of 18 months following termination of employment for any reason, as well as

confidentiality covenants.

Mr. Denham is party to an employment agreement with a term from March 18, 2024 through March 18, 2028. Under this

agreement, Mr. Denham will receive (i) an annual salary of $750,000 and (ii) an annual target bonus opportunity of

$1,700,000, commencing in fiscal year 2024, based on individual and/or Company performance as determined by our

Compensation Committee. This amount was guaranteed for fiscal year 2024, prorated for the length of Mr. Denham's

service in 2024. The agreement provided for an initial restricted stock unit grant (the "Staking Grant") to Mr. Denham of

45,000 shares of the Company's common stock, vesting over three years in equal annual installments on the first three

anniversaries of March 18, 2024, provided that Mr. Denham remains employed through the applicable vesting date. The

agreement also provides that, commencing in December 2024 and for each year during the term of the agreement,

Mr. Denham will be eligible to receive annual equity grants in such form and on such terms as the Board or Compensation

and Committee deems appropriate. Notwithstanding the annual equity grants, the agreement provides for an option grant

of 22,500 shares of the Company's common stock as soon as practicable following March 18, 2024, as well as a grant of

15,000 restricted stock units and an option to purchase 22, 5000 shares of the Company's common stock in December

2024. Pursuant to the agreement, Mr. Denham will receive the following severance benefits if his employment is

terminated by the Company other than for Cause (as defined in the agreement), death or disability and he executes and

does not revoke a general release of claims: (i) the accrued obligations as defined in the agreement; (ii) an amount equal

to the sum of (x) the amount of Mr. Denham's annual base salary as of the termination date and (y) the amount of

Mr. Denham's target annual bonus for the year of termination; (iii) accelerated full vesting of the Staking Grant and (iv) an

extension of the exercise period of any then vested options to purchase shares of Common Stock to the then remaining

term of such vested options. If Mr. Denham's employment is terminated as a result of his death or disability, he will receive

(i) the accrued obligations; (ii) accelerated full vesting of the Staking Grant and (iv) an extension of the exercise period of

any then vested options to purchase shares of Common Stock to the then remaining term of such vested options.

Mr. Denham will be subject to covenants not to compete with the Company or solicit its employees or customers during

his employment and for a period of 12 months following termination of employment for any reason, as well as

confidentiality covenants.

Potential payments on termination<br>

As discussed above, Mr. Hicke's employment agreement entered into in 2022, when he became our Chief Executive

Officer, was replaced in January 2026 by an new employment agreement. Both agreements, among other things, provide

for certain compensation and benefits that are in addition to those provided by us pursuant to those plans and

arrangements available to our employees generally, and those that are customarily (but not required to be) extended to

those executive officers terminated without cause or in the event of their death or disability.

As required by applicable rules of the Securities and Exchange Commission, the following table presents amounts to

which Mr. Hicke would have been entitled as of December 31, 2025, which were thus calculated in accordance with his

2022 employment agreement. This agreement provided that if he were to be terminated without cause prior to

June 1, 2026, and he executes and does not revoke a general release of claims, then in addition to those benefits

generally provided by us to our employees pursuant to those plans and arrangements available to our executive officers

generally and those that are customarily (but not required to be) extended to departing executive officers, Mr. Hicke

will receive:

• an amount equal to any accrued obligations he is owed under the terms of his employment agreement; and

• an amount (the "Severance Amount") equal to the sum of (x) one and one-half times his base salary as of the

termination date, plus (y) one and one-half times his annual bonus for the year of termination, which Severance Amount

would be payable in equal payroll installments during the 18-month period following the year of termination.

**Executive compensation**<br>

Mr. Hicke's 2022 employment agreement also provided that in addition to the benefits customarily (but not required to be)

extended to departing executive officers if he is terminated without cause or his employment ceases for death or disability,

any portion of the 40,000 RSU grant received at the time of his promotion to Chief Executive Officer that has not vested at

the time of such departure will accelerate and the Shares issuable thereunder will be issued to Mr. Hicke and such shares

will be tradeable without restriction.

Any options to purchase Shares that have been or may be granted to Mr. Hicke are not subject to the accelerated vesting

or extended exercise period provisions of his 2022 employment agreement and would be treated in the same manner as

have those options held by other departing executive officers.

Pursuant to the terms of his 2022 employment agreement, Mr. Hicke will be subject to covenants not to compete with the

Company or solicit its employees or customers during his employment and for a period of 18 months following termination

of employment for any reason, as well as confidentiality covenants.

The following table illustrates our estimates of the potential value of the payments and benefits to which Mr. Hicke would

be entitled to receive upon a termination of his employment without cause or upon his death or disability pursuant to his

2022 employment agreement that are in addition to those benefits customarily extended to departing executive officers, in

either case as of December 31, 2025. The amounts that Mr. Hicke would receive in an actual termination can only be

determined at the time the event occurs.

<sup>(1)</sup> The calculation is 1.5 times Mr. Hicke's base salary for 2025 per the terms of his 2022 employment agreement and does not include

the amount of any accrued but unpaid base salary or vacation through the date of termination that may be payable to Mr. Hicke at the

time of termination.

<sup>(2)</sup> The calculation is 1.5 times Mr. Hicke's incentive compensation target for 2025, per the terms of his employment agreement.

<sup>(3)</sup> The aggregate value is based on the closing market price of the Shares on December 31, 2025 ($82.02). As of December 31, 2025,

10,000 Shares underlying Mr. Hicke's 40,000 RSU Staking Grant had not yet vested.

Under Mr. Hicke's January 2026 employment agreement, Mr. Hicke is entitled to receive, subject to entering into and not

revoking, a release agreement with us, the following severance benefits if his employment is terminated by the Company

other than for Cause (as defined in the Employment Agreement), death or disability: (i) the accrued obligations as defined

in the agreement; (ii) an amount equal to (x) one and one half times his base salary as of the termination date and (y) one

and one half times his annual bonus for the year of termination, payable in payroll installments during the 18-month period

following the year of termination; and (iii) accelerated full vesting of any then outstanding unvested equity awards. If

Mr. Hicke's employment is terminated as a result of his death or disability, subject to the execution of the necessary

release agreement, he, or his estate, will receive (i) the accrued obligations as defined in the agreement and

(ii) accelerated full vesting of any then outstanding unvested equity awards. In the event of termination without Cause, or

for death or disability, unexercised options owned by Mr. Hicke will remain exercisable for a period of 18 months

following termination.

In the event Mr. Hicke's employment is terminated without Cause, or he terminates his employment for Good Reason

(as defined in the agreement), within 24 months after a Change in Control (as defined in the agreement), Mr. Hicke will

receive the following severance benefits: (i) the accrued obligations as defined in the agreement; (ii) an amount equal to

(A) the product of 1.5 multiplied by the sum of (x) his base salary as of the termination date, plus (y) his target bonus for

the year in which the termination date occurs, plus, (B) the product of the amount of his then applicable target annual

bonus multiplied by a fraction, the numerator of which of is the number of days Mr. Hicke was employed by the Company

in the calendar year of his termination date, and the denominator of which is 365; and (iii) full accelerated vesting. In the

event Mr. Hicke's employment is terminated without Cause, or he terminates his employment for Good Reason, within

24 months after a Change in Control, the exercise period for any equity awards owned by Mr. Hicke will be automatically

extended until the shorter of (1) the remaining term of such award, and (2) the date that is 365 days from the date of

his termination.

Mr. Denham, our Chief Financial and Chief Operating Officer, also has an employment agreement. Mr. Denham's

employment agreement provides for certain compensation and benefits that are in addition to those provided by us

**Executive compensation**<br>

pursuant to those plans and arrangements available to our employees generally and those that are customarily (but not

required to be) extended to those executive officers terminated without cause or in the event of their death or disability.

Mr. Denham's employment agreement provides that if he is terminated without cause or resigns for Good Reason, as

defined in his employment agreement, prior to March 18, 2028, then in addition to those benefits generally provided by us

to our employees pursuant to those plans and arrangements available to our executive officers generally and those that

are customarily (but not required to be) extended to departing executive officers, Mr. Denham will receive:

• an amount equal to the accrued obligations he is owed under the terms of his employment agreement; and

• an amount (the "Denham Severance Amount") equal to the sum of (x) the amount of his annual base salary as of the

termination date and (y) the amount of his target annual bonus for the year of termination, which Denham Severance

Amount would be payable in equal payroll installments during the 18-month period following the year of termination.

Mr. Denham's employment agreement also provides that in addition to the benefits customarily (but not required to be)

extended to departing executive officers if he is terminated without cause or his employment ceases for death or disability,

any portion of the 45,000 RSU Staking Grant that has not vested at the time of such departure will accelerate and the

Shares issuable thereunder will be issued to Mr. Denham and such shares will be tradeable without restriction. The

exercise period for any vested stock options then held by Mr. Denham will be automatically extended to the termination

date of the relevant options.

Pursuant to the terms of his employment agreement, Mr. Denham will be subject to covenants not to compete with the

Company or solicit its employees or customers during his employment and for a period of 12 months following termination

of employment for any reason, as well as confidentiality covenants.

The following table illustrates our estimates of the potential value of the payments and benefits to which Mr. Denham

would be entitled to receive upon a termination of his employment without cause or upon his death or disability pursuant to

his employment agreement that are in addition to those benefits customarily extended to departing executive officers, in

either case as of December 31, 2025. The amounts that Mr. Denham would receive in an actual termination can only be

determined at the time the event occurs.

<sup>(1)</sup> The calculation is Mr. Denham's base salary for 2025 and does not include the amount of any accrued but unpaid base salary or

vacation through the date of termination that may be payable to Mr. Denham at the time of termination.

<sup>(2)</sup> The calculation is based on the $1,700,000 annual incentive compensation target agreed in Mr. Denham's employment agreement.

<sup>(3)</sup> The aggregate value is based on the closing market price of the Shares on December 31, 2025 ($82.02). As of December 31, 2025,

30,000 Shares underlying Mr. Denham's RSU Staking Grant had not yet vested.

In May 2024, we adopted an Executive Severance and Change of Control Plan (the "Severance Plan"). Under the

Severance Plan, each executive permitted to participate in accordance with the Severance Plan's terms will be entitled

to receive the payments and benefits described below in the event the executive is subject to a Qualifying Termination.

Messrs. Denham, Lane, Sharma and McCabe participate in the Severance Plan. Defined terms used in the following

discussion of the Severance Plan have the respective meanings given to such terms in the Severance Plan. Under the

Severance Plan, if the executive is terminated without Cause or the executive resigns for Good Reason, the executive

shall receive: (i) a cash payment equal to the sum of (x) the product of 1.5 times the sum of (a) the executive's Annual

Base Salary in effect as of the Termination Date, plus (b) the executive's Target Bonus for the year in which the

Termination Date occurs, plus (y) the executive's Pro-Rata Target Bonus for the year in which the Termination Date

occurs; (ii) all unvested Options and Stock Appreciation Rights held by the executive as of the Termination Date shall

continue to vest for a period of 24 months from the Termination Date; (iii) the exercise period for all vested Options and

Stock Appreciation Rights held by the executive as of the Termination Date and any unvested Options and Stock

Appreciation Rights held as of the Termination Date that become vested during the 24-month period after the Termination

shall, in each case, be exercisable for a period equal to the shorter of (a) the 27-month period after the Termination Date,

and (b) the then remaining term of the relevant Option or Stock Appreciation Right; (iv) any unvested Stock Units shall

vest on a pro-rata basis determined by using a fraction, the numerator of which shall be the number of months an

**Executive compensation**<br>

individual Stock Unit award has been held and the denominator of which shall be the total number of months that the

individual Stock Unit Award must be held until it vests; and (v) continued participation in the Company's health and dental

plans with monthly premiums to be paid by the Company for 18 months.

If the executive is terminated as a result of Disability: (i) an amount equal to the executive's Pro-Rata Target Bonus;

(ii) full vesting of all unvested Stock Units held by the executive as of the Termination Date; (iii) full vesting of all unvested

Options and Stock Appreciation Rights held by the executive on the Termination Date; and (iv) all vested Options and

Stock Appreciation Rights held by the executive on the Termination Date (including those for which the vesting was

accelerated pursuant to the foregoing (clause (iii)) shall be exercisable for a period equal to the shorter of (a) the

12-month period after the Termination Date, and (b) the then remaining term of the relevant Option or Stock

Appreciation Right.

If the executive is terminated as a result of death: (i) an amount equal to the executive's Target Bonus for the year in which

the Termination Date occurs; (ii) full vesting of all unvested Stock Units held by the executive as of the Termination Date;

(iii) full vesting of all unvested Options and Stock Appreciation Rights held by the executive on the Termination Date; and

(iv) all vested Options and Stock Appreciation Rights held by the executive on the Termination Date (including those for

which the vesting was accelerated pursuant to the foregoing (clause (iii)) shall be exercisable for a period equal to the

shorter of (a) the 12-month period after the Termination Date, and (b) the then remaining term of the relevant Option or

Stock Appreciation Right.

If the executive terminated as a result of Retirement: all unvested Stock Units, Options, and Stock Appreciation Rights

held by the executive shall continue to vest and be exercisable as if the executive remained employed with the Company,

subject to the executive's compliance with all Restrictive Covenant Obligations after the Termination Date.

If the executive experiences a Qualifying Termination or Retirement during a Change of Control Period: (i) a cash payment

equal to the product of 1.5 times the sum of (a) the executive's Annual Base Salary in effect as of the Termination Date,

plus (b) the executive's Target Bonus for the year in which the Termination Date occurs, plus, (c) the Pro-Rata Target

Bonus for the year in which the Termination Date occurs; (ii) full vesting of all unvested Stock Units, Options, and Stock

Appreciation Rights held by the executive as of the Termination Date, subject to the adjustments described herein, and

(iii) continued participation in the Company's health and dental plans with monthly premiums to be paid by the Company

for 18 months, provided the executive elects continuation coverage pursuant to Section 4980B of the Code and related

guidance. All Options and Stock Appreciation Rights which are fully vested as of the executive's Termination Date shall be

exercisable during the 12-month period immediately following the Termination Date.

An executive's receipt of payments and benefits under the Severance Plan will be conditioned upon the executive's

execution and non-revocation of a general waiver and release of claims in favor of the Company. The Company may

amend or terminate the Severance Plan at any time; provided, however, that no such termination or amendment may

materially and adversely affect any rights of any executive that is entitled to participate in the Severance Plan who has

incurred a Qualifying Termination prior to the date of such termination or amendment; and provided, further that the

Severance Plan cannot be terminated or materially amended during the 24-month period beginning on the date of a

Change of Control.

The following table illustrates our estimates of the potential value of the payments and benefits to which Mr. Denham

would be entitled to receive under the Severance Plan, assuming the applicable termination occurred as of

December 31, 2025.

Pay ratio<br>

Consistent with Instruction 2 to Item 402(u) of Regulation S-K, the applicable SEC rule, we may identify our median

employee for purposes of providing pay ratio disclosure once every three years and calculate and disclose total

compensation for that employee each year; provided that, during the last completed fiscal year, there has been no change

in the employee population or employee compensation arrangements that we reasonably believe would result in a

significant change to the previous year's pay ratio disclosure.

As we had not undertaken a review since December 31, 2022, we chose December 31, 2025 as the date for establishing

the employee population used in identifying the median employee and used fiscal 2025 as the measurement period. We

identified the median employee using a consistently applied compensation measure which includes annual base salary

or wages, target annual performance-based cash bonuses, target commissions, and long-term equity awards based on

their grant date fair values. Permanent employees who joined in 2025 and permanent employees who were on leave

during 2025 were assumed to have worked for the entire year. All U.S. and non-U.S. employees employed as of

December 31, 2025 were captured. No cost-of-living adjustments were made.

With respect to the annual total compensation of our Chief Executive Officer, we included the amount reported for

Mr. Hicke in the "Total" column for 2025 in the Summary Compensation Table included in this Proxy Statement. The

annual total compensation of the median employee and the annual total compensation of the Chief Executive Officer were

calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

each person who served as our principal executive officer ("PEO") and for our Non-PEO named executive officers

<sup>(7)</sup> For the relevant fiscal year, represents the cumulative total shareholder return ("TSR") of the Company for the measurement periods

ending on December 31 of each of 2025, 2024, 2023, 2022 and 2021, respectively.

<sup>(8)</sup> For the relevant fiscal year, represents the cumulative TSR of an Industry Index, a blend of indices including 79% NASDAQ US Asset

Managers and Custodians and 21% NASDAQ US Software for the measurement period ended on December 31, 2025, 2024 and

2023 and 76% NASDAQ US Asset Managers and Custodians and 24% NASDAQ US Software for the measurement periods ended on

of the blended Industry Index is based on the Company's revenue mix for the applicable periods and is intended to provide a more

meaningful performance comparison given its diversified operations.

discretion should be excluded for compensation purposes, divided by (B) the Company's diluted shares outstanding. See Annex A of

this Proxy Statement for a reconciliation of Diluted Earnings Per Share reported in accordance with generally accepted accounting

When calculating our 2025 Adjusted Pre-Tax Earnings Per Share for purposes of our Pay Versus Performance disclosure,

the Committee made the following adjustments to our GAAP earnings per share, which is consistent with the adjustment

the Committee makes when determining whether the EPS vesting targets for outstanding stock options have been met:

• excluded any reduction for stock-based compensation expense associated with stock options in accordance with

Accounting Standards Codification 718 equity compensation (Stock-Based Compensation) from any calculation of the

achievement of EPS vesting targets; and

• excluded the gain on the sale of the Company's Family Office Services business.

The Audit Committee of our Board has selected KPMG LLP ("KPMG") as our independent registered public accounting

firm to audit our consolidated financial statements for the fiscal year ending December 31, 2026. The Audit Committee and

the Board seek to have the Shareholders ratify such an appointment of KPMG by the Audit Committee. We note, however,

that consistent with the requirements of the Sarbanes-Oxley Act of 2002, our Audit Committee has ultimate authority with

respect to the selection of our independent registered public accountants. Accordingly, if Shareholders do not ratify the

appointment of KPMG, our Audit Committee will take that into account in considering whether to continue to retain KPMG.

Representatives of KPMG will be present at the Annual Meeting and will have the opportunity to make a statement, if they

desire to do so, and to respond to appropriate questions.

**Proposal 3: Ratification of appointment of independent registered public accountants**<br>

Policy on audit committee pre-approval of audit and <br>permissible non-audit services of independent <br>registered public accountants<br>

The Audit Committee is responsible for appointing, setting compensation for, and overseeing the work of the independent

auditors. The Audit Committee has established a policy regarding pre-approval of the retention of the independent

auditors for the performance of all audits and lawfully permitted non-audit services and regarding pre-approval of the

fees for such services. On an ongoing basis, management communicates specific projects and categories of service

for which the advance approval of the Audit Committee is requested. The Audit Committee reviews these requests and

advises management if the Audit Committee approves the engagement of the independent auditors to provide these

services, as well as certain fee levels for these services. All of the fees described in the table above were approved by the

Audit Committee. On a periodic basis, management reports to the Audit Committee regarding the actual spending for such

projects and services as compared to the pre-approved fee levels.

**Audit committee report.**

**Notwithstanding anything to the contrary, this Audit Committee Report shall not be deemed** 

**incorporated by reference by any general statement incorporating by reference this Proxy Statement** 

**into any filing under the Securities Act or the Exchange Act except to the extent that we specifically** 

**incorporate this information by reference, and this information shall not be deemed filed under** 

**such Acts.**

The Audit Committee of our Board currently is composed of five independent directors and operates under a written

charter adopted by our Board that complies with the rules adopted by The NASDAQ Stock Market LLC. The Audit

Committee reviews and reassesses the adequacy of its charter on an annual basis. A copy of the current Audit Committee

Charter may be viewed on our website at **seic.com** under "Investor Relations > Leadership > Governance documents."

The members of the Audit Committee are Mr. Romeo (Chair), Mr. Brassington, Mr. Guarino, Ms. McCarthy and Mr. Naratil.

The role of the Audit Committee is to assist our Board in its oversight of the quality and integrity of our financial reporting

process. The Audit Committee also has sole authority, among other things, to retain, set compensation and retention

terms for, terminate, oversee, and evaluate the activities of our independent auditors. Management has the primary

responsibility for the financial reporting process, including the system of internal controls, and for preparation of

consolidated financial statements in accordance with generally accepted accounting principles. Our independent auditors

are responsible for auditing those financial statements and expressing an opinion as to their conformity with generally

accepted accounting principles.

The Committee met five times in 2025 and held discussions with management and the independent auditors.

Management represented to the Audit Committee that our consolidated financial statements were prepared in accordance

with generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated

financial statements with management and the independent auditors. The Audit Committee discussed with the

independent auditors the matters that registered independent public accounting firms must communicate to audit

committees under Public Company Accounting Oversight Board rules.

Our independent auditors also provided to the Audit Committee the written disclosures required by the Public Company

Accounting Oversight Board's independence rules, and the Audit Committee discussed with the independent auditing firm

that firm's independence.

Based upon the Audit Committee's discussions with management and the independent auditors and the Audit

Committee's review of the representation of management and the report of the independent auditors to the

Audit Committee, the Audit Committee recommended that our Board include the audited consolidated financial

statements in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the Securities and

Exchange Commission.

**Other important information.**

**As of the date of this Proxy Statement, management knows of no other matters to be presented for** 

**action at our 2026 Annual Meeting. However, if any further business should properly come before our** 

**2026 Annual Meeting, the persons named as proxies will vote on such business in accordance with** 

**their best judgment.**

Sustainability practices<br>

These practices benefit the environment by minimizing the use of paper and printing and lower our costs.

**Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting**

As permitted by the SEC, we are providing access to our proxy materials online under the SEC's "notice and access"

rules. As a result, beginning on or about April 15, 2026, we mailed or emailed to our shareholders a Notice of Internet

Availability of Proxy Materials with instructions on how to access our proxy materials and our Annual Report to

stockholders for the fiscal year ended December 31, 2025 (the "Annual Report") over the Internet and how to vote. If you

received a notice and would prefer to receive paper copies of the proxy materials and Annual Report, you may request

such materials prior to May 13, 2026: (1) by visiting **www.proxyvote.com**, (2) by calling 1-800-579-1639, or (3) by

emailing **sendmaterial@proxyvote.com**. If sending an email, please include the 16-digit control number found on your

Notice of Internet Availability of Proxy Materials.

**Request Electronic Access to Proxy Materials and Annual Reports**

If you receive your proxy materials by mail, we encourage you to elect electronic delivery. If you do, you will receive an

email with links to access the Proxy Statement and Annual Report on the Internet. If you are a beneficial shareholder,

please contact your broker, bank, or nominee to request electronic access to proxy materials. If your shares are registered

in your name, please access **www.proxyvote.com** to vote. You will have the option to enroll in electronic delivery

immediately after casting your vote.

**Reduce Duplicate Mailings**

We deliver a single Proxy Statement and Annual Report, along with individual proxy cards, to shareholders who have not

enrolled in electronic delivery and share the same address, unless we have received contrary instructions. This practice

is known as "householding." To discontinue householding and receive separate copies of proxy materials, beneficial

shareholders should contact their broker, bank, or nominee where their account is held, and registered shareholders

should contact their account holder or our transfer agent, Equiniti Trust Company, LLC, by phone at (800) 937-5449 or by

email at **help@equiniti.com**.

Access available information about us<br>

We publish our earnings releases on the Investor Relations portion of our website at **seic.com** as well as make available

to shareholders the opportunity to listen to our quarterly earning calls. Our website also provides free-of-charge access to

our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and all amendments

to those reports as soon as reasonably practicable after such materials are filed with the Securities and Exchange

Commission (SEC). Our website and our filings made with the SEC are not part of this Proxy Statement. References

to our website address in this Proxy Statement are intended to be inactive textual references only.

**Other important information**<br>

**Delinquent Section 16(a) Reports**

Section 16(a) of the Exchange Act requires our directors and executive officers and any beneficial owner of more

than 10% of any class of our equity securities to file with the SEC initial reports of beneficial ownership and reports of

changes in ownership of any of our securities. These reports are made on documents referred to as Forms 3, 4 and 5.

Our directors and executive officers must also provide us with copies of these reports. We have reviewed the copies

of the reports that we have received and any written representations that no Form 5 was required from the individuals

required to file the reports that we have received, as well as reviewed Forms 3, 4 and 5 filed with the SEC. Based on

this review, we believe that during the year ended December 31, 2025, each of our directors and executive officers

and beneficial owners of more than 10% of any class of our equity securities timely complied with applicable reporting

requirements for transactions in our equity securities, except for certain reports that were filed late by the following

individuals: Mr. McCabe - one late Form 4 relating to a total of one transaction; Mr. Peterson - one late Form 4 relating to a

total of one transaction; Mr. West - one late Form 4 relating to a total of one transaction; Ms. McCarthy - one late Form 4

relating to a total of one transaction and Mr. Warner - one late Form 4 relating to a total of one transaction.

expenses incurred by them in sending proxy materials to beneficial shareholders.

expectations as to our growth, strategies and the opportunities for our success. You should not place undue reliance on

**Annex A.**

**SEI Investments Company**

Reconciliation of GAAP to non-GAAP measure<br>

The Adjusted Pre-Tax Earnings Per Share results reflected in the "Pay Versus Performance" section of this Proxy

Statement is a non-GAAP financial measure. This non-GAAP financial measure should be viewed in addition to, and not

as a substitute for, reported results prepared in accordance with GAAP. Please refer to the Company's annual reports on

Form 10-K for terms not defined herein.

The Compensation Committee utilizes this non-GAAP measure when determining whether vesting targets for outstanding

stock options have been met. This non-GAAP measure is adjusted to exclude the impact of certain costs, expenses, and

revenue, the exclusion of which the Compensation Committee believes provides an understanding of the results of the

primary operations of the Company's businesses and enhances comparability across fiscal reporting periods. Neither the

Compensation Committee nor management utilize Adjusted Pre-Tax Earnings Per Share for the compensation processes

related to the Company's employees or any other purpose.

The following table reconciles financial results reported in accordance with generally accepted accounting principles

(GAAP) to the non-GAAP financial measure presented in this Proxy Statement.
