SS&C 2025 PROXY STATEMENT | 1

“Our Company reported record revenues and earnings. The higher growth reflects our focus on client service, expansion of our capabilities, and investment in our people.”

L etter from
our CEO and
Chairman

|  | Dear Fellow Stockholders, Thank you for your continued confidence. Our Company reported record revenues and earnings. The higher growth reflects our focus on client service, expansion of our capabilities, and investment in our people. SS&C reported 2024 GAAP revenue of $5,882.0 million, $1,343.5 million in GAAP operating income, and $3.00 in GAAP diluted earnings per share. On an adjusted basis, we posted $5.41 in diluted earnings per share, and $2,281 million in adjusted consolidated EBITDA. We continue to invest in our business to drive organic growth, and spent $584 million on sales and marketing which is up significantly as is the $518 million spent on research and development. Despite growth in those expenditures, we improved our profitability and exited the year with a 38.8% adjusted consolidated EBITDA margin. In 2024, SS&C posted strong organic growth of 6.1%. SS&C generated cash flow from operations of $1,389 million, a 14.3% increase from 2023. We bought back 10.6 million shares, at an average price of $69.15 per share, and paid $245 million in dividends, returning 45% of available cash flow. We paid down $510 million in debt, bringing our net leverage ratio to 2.98x, and our secured net ratio to 1.72x. Additionally, this year we completed the acquisition of Battea Class Action Services, which is a natural cross sell. The opportunity for lift outs, client growth, geographic expansion, and continued implementation of DomaniRx is exciting. We remain committed to maximizing shareholder value and continue to believe in our stock. With industry tailwinds in financial services and with potential for improvement in the M&A markets, we are focused on driving opportunity. Sincerely, William C. Stone Chairman of the Board & Chief Executive Officer

“Our Board of Directors remains focused on long-term value creation for our shareholders.”

L etter from our
Lead Independent
Director

Dear Fellow Stockholders, As Lead Independent Director of the SS&C Board of Directors, I am pleased to report that SS&C demonstrated strong execution in 2024 with consistent financial results, profitability, and a strengthening balance sheet. We achieved record-breaking annual revenues and earnings while maintaining our commitment to investment to drive future growth. Here is an update on the Company’s accomplishments these past twelve months. Our Board of Directors remains focused on long-term value creation for our shareholders. We continue to invest in our business, improve our offerings, and develop our top talent. Our client service focus is a top differentiator and contributes to our strong customer retention rate. We remain committed to listening to our customers and shareholders and keeping up with applicable legal and regulatory requirements in a fast-changing world. Our Board continues to engage with shareholders, and incorporating their feedback into the Board’s decision-making process remains a priority. From May 2024 to March 2025, SS&C met with 14 of our top 20 stockholders, and approximately 58% of our outstanding shares (excluding shares held by our CEO). As part of our ongoing effort to ensure the success and long-term growth of the company, the Nominating and Governance Committee of our Board of Directors remained engaged in its comprehensive director search after onboarding Debra Walton-Ruskin last year. The Board reviewed many candidates, based on referrals and recommendations from Board members and management and through the services of a market leading third-party director search firm. On March 24, 2025, the Board unanimously elected Francesco Vanni d’Archirafi to the Board to fill a vacancy, upon the nomination and recommendation of the Nominating and Governance Committee. Francesco brings a wealth of talents, experience, and insights, and I am pleased to welcome him to the Board. Our Board continues to keep investors, customers, employees, and partners top of mind. We look forward to strengthening the business via accretive acquisitions, pursuit of strategic initiatives and further strengthening of our financial results. On behalf of SS&C’s Board of Directors, thank you for your support as shareholders. Sincerely, Jonathan E. Michael Lead Independent Director |  |

6 | SS&C 2025 PROXY STATEMENT

PROXY SUMMARY

Stockholder Engagement

Our Board considers the feedback of our stockholders as critical to our long-term growth and success and values the input provided when making decisions for our company. Our discussions with stockholders often relate to our executive compensation program and governance matters. We analyze the feedback we receive from our stockholders and discuss it with our independent compensation advisors at Frederic W. Cook & Co. (“FW Cook”) to evaluate our executive compensation program and to facilitate alignment of our compensation program with prevailing market practice and with the promotion of stockholder value creation. We appreciate our stockholders’ willingness to engage with us and to provide their perspectives, and we are committed to maintaining active engagement to understand diverse viewpoints, and to be responsive to stockholder concerns. From May 2024 to March 2025, we met with 14 of our top 20 stockholders, and approximately 58% of our outstanding shares (excluding shares held by our CEO). For additional details regarding engagement with stockholders and consideration of their feedback to our executive compensation program, see the Compensation Discussion & Analysis-Stockholder Engagement on Say-On-Pay on page 35 of this proxy statement.

As described in our 2023 and 2024 proxy statements, the Compensation Committee has taken specific actions in recent years to enhance our executive compensation program in direct response to feedback from our stockholders, including with respect to our annual cash bonus program, long-term incentive programs, as well as providing detailed and transparent disclosure of our compensation decisions, including the following:

•
Annual Cash Bonus Program
•
Adopted a formulaic annual bonus program design consistent with leading best practices
•
Each executive receives a target bonus opportunity for each year, relative to which bonus payouts are determined based on the level of attainment of rigorous pre-established Company financial performance goals (with an up to 25% upward or downward strategic modifier adjustment based on overall business and individual performance against pre-established strategic key performance indicators (“KPIs”))
•
Total payouts capped at 250% of target
•
Earned annual bonuses payable 100% in cash
•
Annual bonuses payable based on the achievement of the following equally-weighted performance metrics: (i) adjusted revenue, (ii) organic revenue growth, (iii) operating cash flow and (iv) adjusted consolidated EBITDA. Each of these performance metrics is evaluated for compensation purposes in the same way as it is presented in public guidance and other measures of the Company’s financial results and performance as communicated to shareholders in our earnings releases
•
Annual Long-Term Incentive Awards
•
Adopted a long-term incentive program that emphasizes pay-for-performance
•
Equity incentives granted based on a target value on the date of grant, which is set by the Compensation Committee after a holistic consideration of competitive data and individual-specific factors
•
Annual award mix emphasizes performance-based awards comprised of performance-based restricted stock units (“PSUs”) (50%), time-based stock options (25%) and time-vesting restricted stock units (“RSUs”) (25%)
•
PSUs vest between 0% and 200% of target based on our achievement of a three-year average earnings per share (“EPS”) growth performance goal, with an up to 20% upward or downward modifier based on our achievement of a relative total shareholder return (“TSR”) performance goal; however, no upward modifier will be applied to PSUs if the Company’s absolute TSR over the performance period is negative
•
Total payout of PSUs cannot exceed 200% including the modifier
•
Disclosure Regarding Incentive Plans
•
Significantly enhanced our disclosure in the proxy statement of annual cash bonus and long-term equity incentive program decisions, including in connection with the selection of performance goals and payout determinations

For additional details regarding the enhancements made to our executive compensation program in recent years, see the Compensation Discussion & Analysis continuing on page 31 of this proxy statement.

In 2024, given stockholders’ continued support and satisfaction with these actions, no additional specific changes were made to our executive compensation programs. We continue to maintain an active dialogue with our stockholders and evaluate feedback on issues of importance to them.

SS&C 2025 PROXY STATEMENT | 7

PROXY SUMMARY

Commitment to Strong Corporate Governance Practices

We believe good corporate governance and high ethical standards are important for us to achieve success and create long-term value for our stockholders. Among our other practices, the following highlight our commitment to corporate governance:

•
Corporate Governance Guidelines. The Company’s Corporate Governance Guidelines address matters such as the roles and responsibilities of the Board, the Board’s leadership structure, the responsibilities of the Lead Independent Director, director independence, overboarding, succession planning and retirement (with a mandatory retirement age of 75), Board membership criteria, Board committees, director orientation and continuing education, and Board and senior management evaluations. Recently, the Board revised our guidelines to add reimbursement for director education programs.
•
Lead Independent Director. The SS&C Board has a Lead Independent Director who is nominated by the Nominating and Governance Committee and unanimously approved by the Board. A Lead Independent Director will be maintained so long as the role of the Board Chairman is combined with that of the Chief Executive Officer.
•
Board Governance Review. The Nominating and Governance Committee reviews the practices and procedures of the Board to evaluate its operating efficiency and strategic focus and recommends enhancements to the Company’s governance documents from time to time to achieve better practices.
•
Cybersecurity Oversight. Cybersecurity risk is overseen by the full Board, with additional oversight of the relevant risk framework and controls provided by the Audit Committee, which oversees our policies with respect to risk assessment and risk management generally. The Audit Committee’s specific oversight includes periodic review of our information security controls and procedures and the processes and procedures for managing cybersecurity risks.
•
Majority Voting. Our Bylaws provide that an uncontested election of directors will be decided by a majority in voting power of votes cast with respect to a nominee’s election. Our Bylaws also require a director to immediately tender his or her resignation if the director fails to receive a majority of votes cast. The acceptance or rejection of a director's resignation would be subject to Board action and subsequent disclosure.
•
Proxy Access. Our Bylaws permit a stockholder or group of stockholders (up to 20) who have owned a significant amount of shares of common stock (at least 3%) for at least three years to submit director nominees (up to 20% of the Board or two directors, whichever is greater) for inclusion in our proxy statement, subject to satisfying the requirements in our Bylaws.
•
Director Experience and Skills Matrix. The Board facilitates disclosure of our directors’ experience and skills to help our stockholders better understand their strengths.
•
Annual Board Performance Evaluation. The Nominating and Governance Committee, at least annually, oversees an annual self-evaluation process by the Board and its committees.
•
Clawback Policies. We maintain two incentive compensation clawback policies. In addition to the compensation clawback policy mandated by the Dodd-Frank Act, we have an additional policy which expands beyond the Dodd-Frank Act requirements and applies to all incentive compensation (including compensation that vests solely on continued service) if our executives’ misconduct is a significant contributing factor to the need for a financial restatement.
•
Environmental, Social and Governance (ESG) Report. The Nominating and Governance Committee provides oversight of the Company’s practices and processes relating to ESG matters, in coordination with other committees of the Board. We work with a leading consultant to assist us with our ESG Report and related ESG transparency and future roadmap.
•
Stock Ownership Guidelines. We maintain stock ownership guidelines under which our directors and executive officers are expected to accumulate and retain a meaningful level of ownership in our stock.
•
Anti-hedging/anti-pledging. We maintain an anti-hedging/anti-pledging policy that prohibits our employees and directors from engaging in transactions that are designed to hedge or speculate on changes in the market value of our common stock.

Prop osal 1:

Election of Class III Directors

Board Structure

Our Restated Certificate of Incorporation provides for a classified Board. This means the Board is divided into three classes, with each class having as nearly as possible an equal number of directors. The term of service of each class of directors is staggered so that the term of one class expires at each annual meeting of our stockholders.

Board Mem ber Elections

At each annual meeting of stockholders, directors are elected for a term of three years to succeed those directors whose term is expiring. Ms. Conjeevaram, Mr. Stone and Mr. Vanni d’Archirafi are current Class III directors whose terms expire at the 2025 annual meeting. Each of these directors has been nominated by the Board upon the recommendation of the Nominating and Governance Committee for reelection as a Class III director, with a term ending at the 2028 annual meeting.

Unless otherwise instructed in the proxy, all proxies will be voted “FOR” the election of each of the nominees identified above to a three-year term ending at the 2028 annual meeting, to hold office until his or her successor has been duly elected and qualified, or until the director’s earlier death, removal, or resignation.

SS&C’s corporate bylaws provide that an uncontested election of directors will be decided by a majority in voting power of votes cast with respect to a nominee’s election. Accordingly, a majority in voting power of the votes cast by holders of all of the shares of common stock present in person or represented by proxy at the 2025 annual meeting is required to elect each nominee as a director.

Each of the nominees has indicated his or her willingness to serve on the Board, if elected. If any nominee is unable to serve, the person acting under the proxy may vote the proxy for a substitute nominee designated by the Board or the Board may reduce its size. If a Class III director nominee fails to receive a majority in voting power of the votes cast, the director must tender his or her resignation to the Board. The Nominating and Governance Committee will consider the resignation and make a recommendation to the Board as to whether to accept or reject the resignation. The Board will act on the resignation, taking into account the Nominating and Governance Committee’s recommendation, and publicly disclose its decision regarding the resignation within 90 days following certification of the election results.

The board of directors recommends that you vote FOR the election of Smita Conjeevaram, William C. Stone and Francesco Vanni d’Archirafi as Class III Directors

Election of Directors

Criteria and S kills of Director Nominees

In considering whether to recommend any particular candidate for inclusion in the Board’s slate of recommended director nominees, the Nominating and Governance Committee applies the criteria specified in its charter. These criteria include the candidate’s:

PROFESSIONALISM Nominees should have a reputation for integrity, honesty and adherence to high ethical standards. |  | EXPERTISE Nominees should demonstrate business acumen, experience and an ability to exercise sound judgments in matters that relate to the current and long-term objectives of the Company, and an ability to contribute positively to the decision-making processes of the Company. |
COMMITMENT Nominees should have a commitment to understanding the Company and its industry and to regularly attending and participating in meetings of the Board and its committees. |  | AWARENESS OF CONSTITUENT INTERESTS Nominees should have the ability to understand the sometimes conflicting interests of stockholders, customers, employees and other constituencies of the Company, and should not have, or appear to have, a conflict of interest. |

In terms of criteria for composition of the Board and Board committees, the Nominating and Governance Committee considers issues of judgment, age, skills, background and experience of the directors, with the goal of providing a significant breadth of experience, knowledge and abilities to assist the Board in fulfilling its responsibilities.

The director biographies above describe each nominee’s experience, qualifications, attributes and skills that led the Board to conclude that he or she should continue to serve as a member of the Board. Our Board believes that each of the nominees has realized significant professional and personal achievements and possesses the background, talents and experience that are necessary for the Company’s success and the creation of stockholder value.

Director Nom ination Process

The process followed by the Nominating and Governance Committee to identify and evaluate director candidates begins with requesting recommendations from Board members, other directors, senior management, third parties and others; holding meetings from time to time to evaluate biographical information and background material relating to potential candidates; and conducting interviews of selected candidates by members of the Nominating and Governance Committee. The Nominating and Governance Committee has engaged a leading third-party search firm, Korn Ferry, to conduct a rigorous search and review process for Board candidates.

| REQUESTING RECOMMENDATIONS FROM · Board Chair · Other Directors · Consulting Firms · Management · Stockholders · Third-party search firm · Other Interested Parties |  | EVALUATION OF POTENTIAL CANDIDATES · Biographical Information · Expertise · Diligence · Ethical Standards |  | CONDUCTING INTERVIEWS OF SELECTED CANDIDATES · Nominating and Governance Committee · Board Chair · Officers · Advisors |  | RECOMMENDATIONS FOR APPOINTMENT TO THE BOARD Successful candidates are recommended by the Nominating and Governance Committee to the full Board of Directors for a vote, and allocated to the appropriate Class. |  | FINAL REVIEW AND SELECTION Board Vote |

Through this process, including consultation by the Nominating and Governance Committee with leading third-party search firm Korn Ferry, the Board elected Francesco Vanni d’Archirafi as an independent member of to the Board on March 24, 2025, to fill a vacancy resulting from an increase in the size of the Board from seven directors to eight directors. Mr. Vanni d’Archirafi was nominated and unanimously recommended by the Nominating and Governance Committee after review of his and other director candidates’ integrity, business acumen, expertise, skills, experience, and other criteria for Board member selection set forth in the Nominating and Governance Committee’s charter and in the Company’s Corporate Governance Guidelines.

18 | SS&C 2025 PROXY STATEMENT

Election of Directors

Stockholders may recommend individuals to the Nominating and Governance Committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background material, to the Nominating and Governance Committee via email at CorpLegal@sscinc.com, attention: Corporate Secretary, SS&C Technologies Holdings, Inc.

TO RECOMMEND A DIRECTOR CANDIDATE, SEND AN EMAIL TO: CorpLegal@sscinc.com, attention: Corporate Secretary, SS&C Technologies Holdings, Inc.

Assuming that appropriate biographical information and background material is provided on a timely basis, the Nominating and Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process and applying substantially the same criteria as it follows for candidates submitted by others.

Stockholders also have the right under our Bylaws to directly nominate director candidates, without any action or recommendation on the part of the Nominating and Governance Committee or the Board. In addition, our Bylaws permit a stockholder, or a group of up to 20 stockholders, owning continuously for at least three years 3% or more of the shares of common stock of the Company, to nominate and include in the Company’s proxy materials for an annual meeting directors constituting up to two individuals or 20% of the Board, whichever is greater, provided that the stockholder(s) and the nominee(s) satisfy the requirements specified in the Bylaws and provided further that so long as the Company has a classified board structure, the maximum number of proxy access nominees in a year shall not exceed one-half of the number of directors to be elected at that annual meeting. See “Stockholder Proposals and Director Nominations” beginning on page 77 below.

STOCKHOLDERS AGREEMENT

The Company is a party to a Stockholders Agreement, as amended, with William C. Stone, our Chairman and Chief Executive Officer. The Stockholders Agreement entitles Mr. Stone to nominate two directors, one of whom shall be Mr. Stone for so long as he is our Chief Executive Officer. For more information on the Stockholders Agreement, see the section of this proxy statement entitled “Related Person Transactions–Stockholders Agreement” beginning on page 27.

Successio n Planning

Succession planning is a top priority for the Board and SS&C’s senior leadership, with the objective of having a pipeline of highly qualified executives. Our Nominating and Governance Committee oversees the Company’s Board and Chief Executive Officer succession planning process. Our Chief Executive Officer also provides the Nominating and Governance Committee with recommendations for, and evaluations of, potential successors. Directors engage with those individuals and other senior management talent at Board and committee meetings and other forums to enable their assessment.

Board Size

The Board sets the number of directors from time to time by a resolution adopted by the Board. The Board has the flexibility to increase or decrease the size of the Board as circumstances warrant. There are currently eight members of the Board, including Mr. Vanni d’Archirafi who was elected by the Board in March 2025 to fill a vacancy resulting from an increase in the size of the Board from seven directors to eight directors. If all of the Board’s nominees are elected, the Board will be composed of eight members immediately following the annual meeting. If any nominee is unable to serve as a director, or if any director leaves the Board between annual meetings, the Board may reduce the number of directors or elect an individual to fill the resulting vacancy.

Director Service on Other Public Company Boards

The Board recognizes that service on other public company boards provides directors valuable experience that benefits the Company. The Board also believes, however, that it is critical that directors dedicate sufficient time to their service on the Company’s Board. Directors are expected to advise the Chair of the Nominating and Governance Committee in advance of accepting any invitation to serve on another public company’s board, or any private company or non-profit board that is expected to require significant commitments of time. This allows the Nominating and Governance Committee to assess the impact of the director joining another board based on various factors relevant to the specific situation, including the nature and extent of a director’s other professional obligations and the time commitment required by the new position. Directors who are engaged in active, full-time employment, for example, could have less time to devote to board service. Our Corporate Governance Guidelines provide that without obtaining the approval of the Board:

•
An independent director may not serve on more than four public company boards, including the Company’s Board; and

SS&C 2025 PROXY STATEMENT | 19

Election of Directors

•
An independent director who is also the chief executive officer of another public company may not serve on more than two public company boards, including the Company’s Board.

Board Determina tion of Independence

Under the applicable rules of the Nasdaq Stock Market, a director will only qualify as an “independent director” if, in the opinion of the Board, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our Board has determined that none of Mses. Conjeevaram or Walton-Ruskin, nor Messrs. Boulanger, Michael, Vanni d’Archirafi, Varsano or Zamkow, has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an “independent director” as defined under Rule 5605(a)(2) of Nasdaq.

Board Meeti ngs and Attendance

During the fiscal year ended December 31, 2024, which we refer to as fiscal 2024, the Board met four times. During fiscal 2024, the Audit Committee held eight meetings; the Compensation Committee held four meetings; and the Nominating and Governance Committee held five meetings. Each of our current directors attended at least 75% of the aggregate of the total number of meetings of the Board and of the Board committees of which she/he was a member during fiscal 2024.

Director Attendance at Annual Meeting of Stockholders

We do not have a formal policy regarding directors’ attendance at annual meetings, but all of our directors are encouraged to attend our annual meetings. All of our then Board members attended our 2024 Annual Meeting of Stockholders.

Board Leadership Structure and Composition

Mr. Stone has served as Chairman of the Board of Directors and Chief Executive Officer since our inception in 1986, and the provisions of the Stockholders Agreement require that so long as Mr. Stone is a member of the Board and the Chief Executive Officer of the Company, he shall serve as Chairman of the Board. We believe that this leadership structure has been effective for us in having one person serve as both Chief Executive Officer and Chairman of the Board, which shows our employees, customers and other constituencies that we are under strong leadership, with a single person both setting the tone and having primary responsibility for managing our operations. We maintain the position of a Lead Independent Director, currently held by Mr. Michael, to act as a strong counterbalance to the combined Chief Executive Officer and Chairman role. We also believe that this leadership structure eliminates the potential for duplication of efforts and inconsistent actions and facilitates open communication between management and the Board. In addition, the Board believes its approach to risk oversight, as more fully discussed below in “Risk Oversight,” helps ensure that the Board is able to effectively perform its risk oversight responsibilities under various leadership structures.

The Corporate Governance Guidelines require the Board to designate a Lead Independent Director, based on the recommendation of the Nominating and Governance Committee, if the role of the Chairman is combined with that of the Chief Executive Officer. Mr. Michael currently serves as Lead Independent Director. The Board believes that Mr. Michael’s tenure and extensive experience in the financial services industry and at insurance companies enable him to bring valuable and independent views to the boardroom. Below is a summary of the key duties and responsibilities of our Lead Independent Director as set forth in our Corporate Governance Guidelines:

•
preside at all meetings of the Board at which the Chair of the Board is not present, including executive sessions of the independent directors; and
•
serve as liaison between the Chair of the Board and the independent directors.

Board Membersh ip Changes

As previously announced on March 26, 2025, the Board elected Mr. Vanni d’Archirafi to the Board to fill a vacancy resulting from an increase in the size of the Board from seven directors to eight directors. Mr. Vanni d’Archirafi was nominated and unanimously recommended by the Nominating and Governance Committee after consultation with leading third-party search firm Korn Ferry and review of his integrity, business acumen, expertise, skills, experience, and other criteria for Board member selection set forth in the Nominating and Governance Committee’s charter and in the Company’s Corporate Governance Guidelines. Mr. Vanni d’Archirafi was elected as a Class III director to serve until the 2025 Annual Meeting of Stockholders and until his successor has been duly elected and qualified. Mr. Vanni d’Archirafi is up for election by the stockholders in Proposal 1 on page 9.

Board Committees

The Board directs the management of our business and affairs, as provided by Delaware law, and conducts its business through meetings of the Board and three standing committees: the Audit Committee, the Compensation Committee and the Nominating and Governance Committee, each of which operates under a charter that has been approved by the Board. Each committee’s charter is posted on our website, at https://investor.ssctech.com/governance/governance-documents/. In addition, from time to time, special committees may be established under the direction of the Board to address specific issues.

CORPORATE GOVERNANCE GUIDELINES

Our Corporate Governance Guidelines provide a transparent framework for the effective governance of the Company. The Corporate Governance Guidelines address matters such as the roles and responsibilities of the Board, the Board’s leadership structure, the responsibilities of the Lead Independent Director, director independence, overboarding, succession planning, Board membership criteria, Board committees, director orientation and continuing education, and Board and senior management evaluations. The Nominating and Governance Committee is responsible for reviewing the Corporate Governance Guidelines and overseeing compliance with such guidelines.

CODE OF BUSINESS CONDUCT AND ETHICS

We maintain a written code of business conduct and ethics, referred to as the SS&C Code of Business Conduct and Ethics, which covers all directors, officers and employees, and includes provisions relating to accounting and financial matters. Our employees are required to acknowledge that they have read and understood the Code of Business Conduct and Ethics and will act accordingly as a condition of employment. Training is conducted for all employees upon hire and annually after that. Our Chief Financial Officer and General Counsel are responsible for overseeing the Code of Business Conduct and Ethics.

SS&C provides a facility for the reporting, investigation and resolution of complaints received regarding accounting, internal accounting controls or auditing matters. Our Chief Financial Officer and General Counsel monitor our whistleblower hotline, and all calls are investigated. Business unit-specific internal investigations committees meet quarterly to discuss significant matters and verify potential violations are resolved.

The SS&C Code of Business Conduct and Ethics is available on our website at https://investor.ssctech.com/governance/governance-documents. If we make any substantive amendments to, or grant any waivers from, the SS&C Code of Business Conduct and Ethics for any director or officer, we will disclose the nature of such amendment or waiver on our website at https://investor.ssctech.com/governance/governance-documents or in a Current Report on Form 8-K filed with the SEC.

RELATED PERSON TRANSACTIONS

Policies and Procedures for Related Person Transactions

The Board has maintained written policies and procedures for the review of any transaction, arrangement or relationship in which we have been or are a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a “related person,” has had or has a direct or indirect material interest. Such a transaction, arrangement or relationship is referred to as a “related person transaction.”

Any related person transaction must be reported to our General Counsel and will be reviewed and approved by the Audit Committee in accordance with the terms of the policy, prior to effectiveness or consummation of the transaction, whenever practicable. In addition, any related person transaction previously approved by the Audit Committee or otherwise already existing and ongoing in nature will be reviewed by the Audit Committee annually to ensure that it has been conducted in accordance with the previous approval granted by the Audit Committee, if any, and that all required disclosures regarding the related person transaction are made.

A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the Audit Committee after full disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the Audit Committee will review and consider:

• the related person’s interest in the related person transaction; • the approximate dollar value of the amount involved in the related person transaction; • the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss; • whether the transaction was undertaken in the ordinary course of our business; • whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party; • the purpose of, and the potential benefits to us of, the transaction; and • any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

26 | SS&C 2025 PROXY STATEMENT

Election of Directors

The Audit Committee may approve or ratify the related person transaction only if the Audit Committee determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. The Audit Committee may, in its sole discretion, impose any conditions it deems appropriate on the Company or the related person in connection with approval of the related person transaction.

In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, the Board has determined that the following do not create a material direct or indirect interest on behalf of a related person and, therefore, are not related person transactions for purposes of our related person transaction policy:

•
interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director of such entity) that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity, (b) the related person and her/his immediate family members (as defined in the policy) are not involved in the negotiation of the terms of the transaction with the Company and do not receive any special benefits as a result of the transaction or (c) the amount involved in the transaction equals less than the greater of $200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction; or
•
a transaction that is specifically contemplated by provisions of the Restated Certificate of Incorporation or Bylaws of the Company.

The policy provides that transactions involving compensation of executive officers will be reviewed and approved by the Compensation Committee in the manner specified in its charter.

STOCKHOLDERS AGREEMENT

The Company is a party to a Stockholders Agreement with Mr. Stone that entitles him, if he holds greater than 15% of our common stock, to nominate two directors, one of whom shall be Mr. Stone for so long as he is our Chief Executive Officer. If Mr. Stone holds less than 15% of our common stock, he is entitled to nominate one director (including himself) to the Board. Mr. Stone’s rights under the Board nomination provisions of the Stockholders Agreement will terminate at such time as he holds less than 10% of our common stock.

The provisions of the Stockholders Agreement also require that, so long as Mr. Stone is a member of the Board and the Chief Executive Officer of the Company, he will serve as Chairman of the Board.

REGISTRATION RIGHTS AGREEMENT

The Company and Mr. Stone are parties to a Registration Rights Agreement, under which Mr. Stone can demand that we file a registration statement for all or a portion of his common stock. Mr. Stone is also entitled to request that his shares be covered by a registration statement that we are otherwise filing with respect to our common stock. In either event, the Company is required to pay all expenses of Mr. Stone in connection with the registration (other than underwriting discounts and commissions and transfer taxes applicable to the sale of registerable securities). The Registration Rights Agreement also provides that the Company will indemnify Mr. Stone, and Mr. Stone will indemnify the Company, for certain matters in connection with the registration of Mr. Stone’s shares. The registration rights in the Registration Rights Agreement are subject to certain conditions and limitations specified in the Registration Rights Agreement, including the right of the underwriters of an offering to limit the number of shares included in certain registrations.

PREFERRED STOCK INVESTMENT

On February 27, 2020, the Company entered into a Series A Convertible Share Purchase Agreement with SILAC, Inc. (“SILAC”), pursuant to which the Company acquired 40 million shares of series A convertible preferred stock of SILAC for a purchase price of $40.0 million. Mr. William C. Stone, our Chairman of the Board of Directors and Chief Executive Officer, has an economic interest in SILAC and is a member of its board of directors. Accordingly, the transaction constitutes a “related person transaction” under our related person transaction policy. The Audit Committee and the independent members of the Board of Directors authorized and approved the transaction, and additional transactions up to an aggregate of $5 million. Mr. Stone did not participate in the Board of Directors’ consideration of the transaction.

On October 27, 2020, the Company entered into the first of multiple contracts with SILAC (each, a “Contract”). On and after October 27, 2020, the Company has entered into Contracts pursuant to which the Company provides services to SILAC from time to time as set forth therein. The Audit Committee and the independent members of the Board of Directors approved the Company’s entry into the Contracts. For the year ended December 31, 2024, we generated $0.3 million in revenue under the Contracts.

In March 2025, SILAC authorized, and SILAC made the payment of, an $8 million annual preferred dividend to the Company.

Non-Employee Director Compensation

In consultation with its independent compensation consultant, FW Cook, the Board has adopted a market-competitive non-employee director compensation program to help attract and retain talented individuals to serve as our Board members. Under this program, our non-employee directors are eligible to receive an annual cash retainer of $90,000, plus additional cash compensation for services as follows: Lead Independent Director: $50,000; Audit Committee Chair: $30,000; Compensation Committee Chair: $25,000; and Nominating and Governance Committee Chair: $20,000.

Election of Directors

We maintain ownership guidelines under which our directors are expected to accumulate and retain a meaningful level of ownership in our stock. Under the stock ownership guidelines, directors are required to hold stock having value equal to at least 5X their annual board cash retainer. As of December 31, 2024, each of our non-employee directors was in compliance with our stock ownership guidelines.

For purposes of determining compliance with the ownership guidelines, the following shares are counted as being owned:

•
Shares owned by the director, individually or jointly with such person’s spouse;
•
Shares held in a trust established by the director for the benefit of such person and/or his or her family members;
•
Shares underlying any vested deferred stock units held by the director; and
•
50% of shares underlying unvested of time-based restricted stock or restricted stock unit awards.

In 2024, we revised the stock ownership guidelines so that shares underlying the in-the-money portion of vested, unexercised stock options no longer count toward satisfaction of the ownership thresholds.

Additionally, shares underlying unvested and unearned performance awards or unvested stock options do not count toward satisfaction of the ownership thresholds. There are no time periods within which a director must attain the applicable stock ownership level.

We also have adopted an anti-hedging/anti-pledging policy that prohibits our directors from engaging in any transactions that are designed to hedge or speculate on any change in the market value of our common stock.

Our executive compensation programs are designed to attract, retain and motivate our named executive officers, who are critical to our success. Under these programs, our named executive officers are rewarded for successful performance on our near-term and longer-term financial and strategic goals and for driving corporate financial performance and stability. The programs contain elements of cash and equity-based compensation and are designed to align the interests of our executives with those of our stockholders.

We have designed the annual cash bonus and long-term incentive program components of our executive compensation program in response to feedback we received from stockholders through a robust stockholder engagement process in 2022 and 2023. In 2024, we maintained the same programs that were implemented as a result of this process. Our programs are designed to ensure that our executive compensation aligns with prevailing market practice and promotes pay for performance.

In particular, we have adopted a formulaic annual cash bonus program under which target bonus opportunities are established for each executive and are earned and paid in cash based on the achievement of pre-established, objective performance metrics. In addition, our long-term incentive program reflects a market-based award mix of performance-vesting stock units (PSUs), time-based stock options and time-vesting RSUs, with awards granted based on an aggregate target value on the date of grant, rather than a target number of shares, to promote year-over-year stability and align with prevailing market practice.

At the 2023 annual meeting, shareholders had the opportunity to vote, on an advisory, non-binding basis, on the frequency of our “say-on-pay” votes. Shareholders supported a resolution that we hold a “say-on-pay” vote every year in accordance with the Board’s recommendation. Accordingly, we will be holding “say-on-pay” votes on an annual basis, with the next “say-on-pay” vote to occur at the 2026 Annual Meeting of Stockholders.

For additional details regarding the components of our executive compensation program, see the Compensation Discussion & Analysis continuing on page 38 of this proxy statement.

The Board is asking stockholders to approve a non-binding advisory vote on the following resolution. This vote is advisory and therefore not binding on the Company, the Compensation Committee or the Board. The Board and the Compensation Committee value the opinions of our stockholders and, to the extent there is any significant vote against the named executive officer compensation as disclosed in this proxy statement, we will consider those stockholders’ concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

RESOLVED, that the compensation paid to our named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the compensation discussion and analysis, the compensation tables and any related narrative disclosures in this proxy statement, is hereby approved.

The board of directors recommends that you vote to approve the compensation of our named executive officers by voting FOR proposal 2.

Compensation D iscussion and Analysis

This Compensation Discussion and Analysis section (referred to as the “CD&A”) summarizes our general philosophy regarding the compensation of our Chief Executive Officer (“CEO”), our Chief Financial Officer (“CFO”), and our two other executive officers in 2024 (collectively referred to as “named executive officers” or “NEOs”). The CD&A provides context for the executive compensation disclosures presented below in both tabular and narrative form. The Compensation Committee believes our executive compensation program provides a direct link between our NEOs’ pay and long-term stockholder value creation.

Our NEOs for 2024 are as follows:

Name | Position
William C. Stone | Chairman of the Board and Chief Executive Officer
Rahul Kanwar | President and Chief Operating Officer
Brian N. Schell | Executive Vice President and Chief Financial Officer
Jason White | Senior Vice President, General Counsel and Secretary

EXECUTIVE SUMMARY

The Compensation Committee believes that our executive compensation program should provide a meaningful and direct link between our executives’ interests and those of our stockholders. As a result, the Compensation Committee is committed to our ongoing engagement with stockholders to ensure a clear understanding of how we use our compensation program to ensure alignment between pay and performance, as measured by both operating results and changes in shareholder value, and to be responsive to stockholder feedback. The Compensation Committee chose the performance metrics described below because the Committee believes that these metrics best track the execution of our strategic plan and, in turn, directly translate into the creation of value for our stockholders.

Our Compe nsation Program

OVERVIEW

In response to feedback received from engagement with stockholders in 2022 and 2023, the Compensation Committee, together with its independent compensation consultant, FW Cook, has designed our executive compensation program to strengthen our commitment to our pay for performance philosophy and to closely align our overall program with prevailing market views on best practices, thereby ensuring a strong tie between realized pay and performance and the alignment of the interests of our executive team with our stockholders.

Performance Goals Pr omote Strategic Execution and Shareholder Value Creation

In designing our compensation program, the Compensation Committee focuses on ensuring that our compensation program closely aligns the interests of our NEOs with those of stockholders by incorporating financial performance measures that compensate our NEOs for the execution of our strategic plan, which is intended to create stockholder value. For 2024, the Compensation Committee, together with FW Cook and in consultation with our CEO, selected the performance measures set forth in the following table for use in our annual bonus program and long-term incentive program. These performance measures were unchanged from 2023 as the Compensation Committee believes they holistically reflect our compensation strategy. The Compensation Committee believes that the interplay of the four annual financial performance metrics under our annual bonus program combined with the three-year adjusted EPS growth metric and relative TSR modifier under our long-term incentive program complement one another and provide quantitative, objective performance goals that strongly link our NEOs’ pay with Company performance against key measures of success and stockholder value creation.

Annual Bonus Program | Adjusted Revenue | Measures top-line revenue performance of the Company
Organic Revenue Growth | Measures the growth of SS&C’s core business apart from the effects of acquisitions
Operating Cash Flow | Measures cash after capital investments that allow us to repay indebtedness, make strategic investments and return capital to shareholders
Adjusted Consolidated EBITDA | Key profitability measure, which gauges the costs of the Company’s capital structure and is used in the Company’s senior credit facilities
Long-Term Incentive Program | Adjusted EPS Growth | Reflects profitability growth on a per-share basis over a 3-year period
Relative TSR Modifier | Measures the total shareholder return of investing in the Company against the Company’s disclosed peers over a three-year period

Pay for P erformance

For 2024, approximately 96% our CEO’s and 94% of our other NEOs’ (on average) total direct compensation was performance-based and reflects the Compensation Committee’s review of our overall financial performance.

In furtherance of our pay for performance philosophy, the Compensation Committee made compensation decisions for 2024 that are directly reflective and correlative of the Company’s business and operational performance achievements in 2024 as shown above. This relationship between pay and performance exemplifies the Compensation Committee’s commitment to establish a direct link between executive pay and tangible strategic and financial results. Specifically:

•
We achieved performance between the target and maximum levels in each of the annual bonus metrics during 2024. The aggregate results led to an overall 2024 bonus payout to our named executive officers of 189.5% of target levels. The amount earned for each metric ranged from 153.5% for operating cash flow to 212.6% for adjusted revenue.
•
The strategic modifier component of the annual bonus program enables the Compensation Committee to evaluate overall business and individual performance and determine whether an upward or downward adjustment is appropriate in light of a number of factors, including the macro-economic environment; for 2024, the Compensation Committee determined that no adjustment would be applied under the strategic modifier component of the 2024 annual bonus program.
•
We utilize rigorous performance goals in our long-term equity incentive program that provide payouts upon attaining high levels of sustained performance. For the PSOs granted to our NEOs (other than Mr. Schell) in December 2021 (which had a 2022-2024 performance period), the awards paid out at 81.76%. For additional details regarding the payout of these awards, see “Performance-based stock option performance period that concluded in 2024” on page 43 of this proxy statement.

Compensation Best Practices

We strive to ensure that executive pay decisions are quantitative, transparent and performance-based in order to keep the incentives for our executives aligned with the interests of our stockholders. The following table describes the highlights of our executive compensation practices, each of which is described in more detail elsewhere in this proxy statement:

|  | WHAT WE DO |  |  | WHAT WE DON’T DO
|  | Require the Compensation Committee to solely comprise of independent board members |  |  | Don’t provide excise tax gross ups to our executive officers
|  | Utilize an independent compensation consultant engaged by the Compensation Committee |  |  | Don’t provide excess perquisites or personal benefits to our executive officers
|  | Emphasize pay for performance and consider competitive data in setting our executive’s compensation |  |  | Don’t allow for repricing or cash buyouts of underwater stock options and stock appreciation rights without stockholder consent
|  | Provide formula-based annual cash incentive opportunities
|  | Cap payouts on annual bonuses and PSU awards |  |  | Don’t allow our executives to engage in any transactions that are designed to hedge or pledge company stock
|  | Apply rigorous performance goals to annual and multi-year performance awards
|  | Review and consider executive officer compensation in connection with a peer group, as a market-based reference point |  |  | No acceleration of equity awards on a “single-trigger” basis on a change in control for our named executive officers for grants made on or after December 2020
|  | Maintain stock ownership guidelines for our executives and non-employee directors that promote accumulation and retention of our stock with market leading levels of required stock ownership (e.g., 10x salary for our CEO)
|  | Maintain two incentive compensation clawback policies - one mandated by the Dodd-Frank Act applying to incentive compensation awarded to our executives based on a financial measure in the event of a financial restatement without regard to fault or misconduct by our executives, and a second policy going beyond Dodd-Frank Act requirements, and applying to all incentive compensation, including cash bonuses and time-based vesting awards (in addition to performance based incentive awards and other incentive compensation based on a financial measure), if our executives’ misconduct is a significant contributing factor to the need for a financial restatement |  |  | Don’t pay dividends or dividend equivalents in respect of any unvested or unearned equity awards
|  | Grant at least half of a senior executive’s annual long-term incentives in the form of performance-based awards |  |  | Don’t maintain any defined benefit pension plans or supplemental executive retirement plans for our executives

Stockholder Engagement on Say-on-Pay

Our executive compensation program and practices were designed by the Compensation Committee, together with its independent compensation consultant, FW Cook, in direct response to feedback we received from our stockholders as part of our engagement efforts in 2022 and 2023 that were described in detail in our 2023 proxy statement. We are appreciative of the strong support of our stockholders as evidenced by the results of our say-on-pay vote at our 2023 and 2024 annual meetings, in which 88% of stockholders at each meeting approved our executive compensation program.

The Compensation Committee and management team are committed to continued active engagement with stockholders to understand their viewpoints and to discuss and demonstrate the important connection between our compensation program and stockholder interests. From May 2024 to March 2025, as part of our year-round engagement process, we met with 14 of our top 20 stockholders, and approximately 58% of our shares outstanding (excluding shares held by our CEO) to discuss a wide range of topics including our corporate governance practices, executive compensation program, and corporate responsibility initiatives (including ESG). None of the shareholders expressed significant concerns with respect to our compensation program, and our shareholders generally reacted positively to the design and structure of the executive compensation program that has been in place over the past few years.

The Compensation Committee, with the assistance of FW Cook, continues to evaluate our compensation program design. The Compensation Committee believes that the current design of the compensation program is consistent with our compensation philosophy and objectives and aligns the interests of our NEOs with our long-term goals and the interests of our stockholders without incentivizing inappropriate risk taking.

We will continue to maintain an active dialogue with our stockholders and evaluate feedback on issues of importance to them, including by holding an annual “say-on-pay” vote, in line with the advisory “say-on-frequency” vote of our stockholders at the 2023 annual meeting.

Process for Administering Our Executive Compensation Practices

The Compensation Committee has overall responsibility for administering our executive officer compensation program. As the structure and key features of our executive compensation have evolved in response to stockholder feedback, so too has the Compensation Committee’s approach to its decision-making process around executive pay and goal setting. The Compensation Committee, with the assistance of FW Cook, and based on the input and recommendations it receives from the Chief Executive Officer (other than with respect to his own compensation) and comparative peer group market data, makes decisions regarding the annual total direct compensation levels of our executive officers. This information is also considered in establishing the financial and operational performance metrics that apply to our annual bonus and long-term incentive compensation programs.

In December of each year, the Compensation Committee establishes its agenda for the upcoming year, taking into account Company performance over the prior year and macro-economic conditions, and based on that initial agenda, takes the following actions during the following year at such times noted below (in addition to any other business that may arise during the year):

January-March |
• Review and assess business and individual performance against prior year metrics • Certify performance results and determine compensation payout levels for the prior year • Review compensation policies and assess the risks arising from them
• Review corporate goals and objectives for current year • Establish target pay levels, including approval of performance metrics and goal calibration for the annual bonus programs and PSU grants in the current year • Approve annual equity incentive grants for the current year
April-December |
• Review say-on-pay results and engage with stockholders • Consider and review adjustments to compensation programs based on feedback received from stockholders and evolving strategic objectives • Review compensation peer group, peer group pay levels for executives and non-employee directors, and market trends • Review compensation policies, including any required modifications based on regulatory developments • Develop agenda for following compensation year

Guidance from Independent Compensation Consultant

Since 2020, the Compensation Committee has engaged FW Cook as its independent compensation consultant to provide advice and analysis to the Compensation Committee as part of its comprehensive review of our executive compensation programs. FW Cook’s assistance includes competitive market analysis of our pay for performance alignment, incentive program design, and market positioning among our peer group, which informs the Compensation Committee’s decision-making.

FW Cook is retained by and reports to the Compensation Committee and, upon the request of the Compensation Committee, participates in committee meetings. Other than services provided to the Compensation Committee, FW Cook did not provide any services to the Company in 2024.

Each year, the Compensation Committee evaluates the independence of its compensation consultant to determine whether the services provided by the consultant raise any conflicts of interest, and has determined that its engagement of FW Cook has not presented any conflicts of interest.

Input from Management

The Compensation Committee also solicits input from our Chief Executive Officer, who typically presents salary, bonus and equity compensation recommendations for our executive officers (other than himself) to the Compensation Committee based on his years of experience in the financial services and software industries, his day-to-day engagement with the management team, and his desire to motivate the executive officers and ensure their commitment to the Company. Specifically, for each executive officer, our Chief Executive Officer will offer a description for the Compensation Committee of the officer’s performance during the prior year, and will make a recommendation as to salary, bonus and equity awards based upon the officer’s responsibilities and contributions to the Company’s performance. The Compensation Committee considers these recommendations and discusses his reviews and recommendations with him as part of its deliberations. For our Chief Executive Officer’s compensation, the Compensation Committee conducts its deliberations without him present. In this determination, as in other compensation matters, the Compensation Committee exercises its independent judgment.

Competitive Landscape

Working with FW Cook, the Compensation Committee establishes a peer group from which it reviews relevant competitive compensation data to help inform its decisions regarding executive pay levels and program design. For 2024 executive compensation, the peer group was unchanged from the list set forth in the 2024 Executive Compensation Program Changes section of our 2024 Proxy (“2024 Peer Group”), except for the removal of VMware due to its merger with another company not in our 2024 Peer Group. The 2024 Peer Group was initially recommended by FW Cook and re-approved by the Compensation Committee considering company size, industry relevance, and shared client base. The group is constructed such that, in totality, it represents a reasonable market reference point, placing us near the median of the group in terms of revenue. This group is reviewed annually for continued suitability. The 17 companies comprising the 2024 Peer Group for 2024 executive officer compensation are:

2024 Peer Group

• Autodesk (Nasdaq: ADSK) • Block (f.k.a Square) (NYSE: SQ) • Bread Financial Holdings (f.k.a. Alliance Data Systems) (NYSE: BFH) • Broadridge Financial Solutions (NYSE: BR) • Concentrix (Nasdaq: CNXC) • DXC Technology (NYSE: DXC) • Euronet Worldwide (Nasdaq: EEFT) • FactSet Research Systems (NYSE: FDS) | • Global Payments (NYSE: GPN) • Intuit (Nasdaq: INTU) • Jack Henry & Associates (Nasdaq: JKHY) • Maximus (NYSE: MMS) • Palo Alto Networks (Nasdaq: PANW) • Paychex (Nasdaq: PAYX) • Synopsys (Nasdaq: SNPS) • The Western Union Company (NYSE: WU) • Workday (Nasdaq: WDAY)

Design and Structure of Executive Compensation

Executive Compensation Objectives

Our executive compensation program is designed to foster a performance-based culture among our employees that aligns their interests with those of our stockholders. The primary objectives of the Compensation Committee with respect to executive compensation are to:

•
attract, retain and motivate the best possible executive talent;
•
reward achievement of our strategic objectives by the NEOs and the Company; and
•
align the interests of the NEOs with those of our stockholders by emphasizing performance-based compensation.

To achieve these objectives, our executive compensation program employs a variety of elements, the interplay of which results in a compensation program that is strongly aligned with stockholder interests, retains a talented executive team that is critical to executing on our agenda and rewards them for creating value for our stockholders over the short- and long-term.

Target Compensation Mix Under our Compensation Program

Our executive compensation program consists primarily of three elements – base salary, annual cash bonus and long-term equity incentives – that are designed to link compensation delivered to our executive officers with objective financial criteria and performance and the interests of our stockholders. The below graphs reflect the relative mix of the key components of our executive compensation program (reflected at 2024 target) which demonstrate our commitment to our pay for performance philosophy by tying a significant portion of executive pay to at-risk, variable compensation elements.

Base Salary

Base salary is used to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers, and is the only fixed component of our executive compensation program. Base salaries are reviewed at least annually by the Compensation Committee and are adjusted from time to time to realign salaries with market levels after taking into account the performance of the Company and each executive officer’s responsibilities, performance and experience. In establishing base salaries for 2024, the Compensation Committee considered a variety of factors, including competitive market data, the seniority of the individual, the level of the individual’s responsibility, the Company’s ability to replace the individual, the individual’s tenure at the Company, relative pay among the executive officers, and our Chief Executive Officer’s input. The Compensation Committee deliberates and approves the base salary of our Chief Executive Officer without his presence.

The Compensation Committee approved an annual target total cash compensation structure for each of our NEOs, including the base salaries set forth in the table below and the annual target bonus opportunities set forth under “Annual Bonus” below. 2024 base salaries were maintained at the same levels as 2023. Additionally, the Compensation Committee determined not to increase base salaries for 2025. The following table shows the annual base salaries of our NEOs for 2024 and 2025.

Annual Bonus

Our Annual Bonus Program

We maintain a formulaic, target-based annual bonus program that aims to provide incentives to our executive officers that drive annual performance based on our operating plan and individual performance goals, while retaining the ability to adjust payouts based on the Compensation Committee’s holistic assessment of overall Company performance in the business environment and each NEO’s individual performance during the year (which we refer to as the “strategic modifier”). At the beginning of each year, the Compensation Committee, with input from our management team, will establish target bonus opportunities as well as corporate performance factors and payout formulas. The performance goals are intended to be rigorous and promote our agenda to create stockholder value.

2024 Target Bonus Opportunity

The Compensation Committee established the following target bonus opportunities for each of our NEOs in 2024, which were set considering competitive data from our 2024 Peer Group, and which were maintained at the same levels as 2023.

Named Executive Officer |  | 2024 Target Bonus Opportunity ($)
William C. Stone |  |  |  | $5,000,000
Rahul Kanwar |  |  |  | $4,000,000
Brian N. Schell |  |  |  | $1,400,000
Jason White |  |  |  | $1,000,000

Components of 2024 Annual Bonus Program

The components of our 2024 annual bonus program included a company performance factor consisting of four equally-weighted performance metrics, representing key drivers of sustainable stockholder value creation for our Company, and an individual strategic modifier. Achievement of the company performance factor is based on the level of attainment of rigorous pre-established financial performance goals set forth below, while the strategic modifier is intended to provide the Compensation Committee with an opportunity to make an upwards or downwards adjustment of as much as 25% based on a holistic assessment of overall Company performance in the business environment and each executive’s performance against pre-established strategic KPIs. This strategic modifier provides the Compensation Committee with the ability to more closely tailor annual bonus payouts based on its evaluation of strategic goal attainment and an assessment of individual performance over the year, thereby further reinforcing the Company’s culture of performance and accountability. The target achievement levels established for the Company performance factors used for the 2024 performance year aligned with guidance that the Company provided to the market in connection with our Q4 and Full Year 2023 Earnings Results shared on February 13, 2024. Actual bonus payouts for each NEO ranges between 50% and 250% of his or her target annual bonus opportunity, provided that no payout is provided for any metric that does not achieve threshold performance and if achievement of all company performance factors is less than threshold performance, then there is no payout of annual bonuses. Payouts are linearly interpolated for achievement between stated performance levels.

Adjusted Revenue, Organic Revenue Growth, Operating Cash Flow and Adjusted Consolidated EBITDA are non-GAAP financial measures. See Appendix A for definitions and reconciliations of all non-GAAP financial measures referenced herein.

For the 2024 performance year, the Compensation Committee selected the following strategic modifier KPI categories under the annual bonus program: (i) strategic initiatives (e.g., product launches, acquisitions and divestitures), (ii) human capital management (e.g., employee engagement, leadership and exemplification of culture and values and succession/leadership development); and (iii) individual leadership goals and objectives. The Compensation Committee, with input from our CEO, takes a measured approach on this performance review to ensure that our executives are appropriately motivated and incentivized to continue to perform at high levels and to avoid any incentives for excessive risk-taking.

2024 Annual Bonus Program Results

In early 2025, the Compensation Committee assessed the Company’s achievement of the company performance factor and made final decisions with respect to application of the strategic modifier and payout of 2024 annual bonuses. The table below sets forth the achievement of each financial metric under the company performance factor of the 2024 bonus program. The 2024 targets for each company performance factor metric reflects growth from 2023 actual results. Based on this achievement, the aggregate achievement of the company performance factor was determined to be 189.5% of target levels (with dollar amounts in the table reflected in millions).

In determining the achievement of the Company Performance Factor metrics under our 2024 annual bonus program, the Compensation Committee reviewed and approved an adjustment to the Adjusted Revenue, Operating Cash Flow and Adjusted Consolidated EBITDA metrics to account for the impact of foreign currency exchange rate fluctuations, which resulted in a downward adjustment of $9.8 million to the Adjusted Revenue metric, $3.6 million to the Operating Cash Flow metric and $3.6 million to the Adjusted Consolidated EBITDA metric under the 2024 annual bonus program. Accordingly, the above stated actual results for the Adjusted Revenue, Operating Cash Flow and Adjusted Consolidated EBITDA metrics utilized under our 2024 annual bonus program is different from that used by us for other purposes, including as described on page 33 of this Proxy Statement.

The Compensation Committee also considered the achievement against the strategic KPI categories described above as well as relative Company performance in the macro business environment. Following robust discussions, the Compensation Committee determined that no upward or downward modifier would be applied to the NEOs’ annual bonus payouts for 2024 under the strategic modifier component of our annual bonus program for 2024.

The table below reflects the actual annual bonuses awarded to our named executive officers for 2024 performance.

Long-Term Ince ntive Equity Awards

The Compensation Committee believes that equity-based long-term incentive compensation is a critical component of our executive compensation program and is committed to the use of a program that appropriately motivates and incentivizes our NEOs and aligns their interests with those of our stockholders. Our long-term incentive compensation program has evolved over recent years to incorporate and emphasize performance-based equity awards that are intended to promote alignment of our executive interests with those of our stockholders and to promote long-term stockholder value creation.

Since 2023, grants under the long-term incentive program are comprised of 50% of PSUs, 25% of time-based stock options and 25% of RSUs, and each NEO receives equity incentive awards based on an aggregate target value on the date of grant (as opposed to a target share number). The targeted grant date fair value is determined by the Compensation Committee each year after a holistic consideration of competitive data and individual-specific factors for our executive officers.

The table below sets forth the approved target value for each of the equity awards granted to our NEOs under our compensation program in 2024, which were maintained at the same levels as 2023.

Name |  | PSUs ($) | Stock Options ($) | RSUs ($) | Aggregate Target Value ($)
William C. Stone |  |  | $7,500,000 |  |  | $3,750,000 |  |  | $3,750,000 |  |  | $15,000,000 |
Rahul Kanwar |  |  | $6,000,000 |  |  | $3,000,000 |  |  | $3,000,000 |  |  | $12,000,000 |
Brian N. Schell |  |  | $2,000,000 |  |  | $1,000,000 |  |  | $1,000,000 |  |  | $4,000,000 |
Jason White |  |  | $2,250,000 |  |  | $1,125,000 |  |  | $1,125,000 |  |  | $4,500,000 |

PSUs

To foster strong focus on long-term performance and changes in shareholder value, PSUs are the most significant single component of the annual award mix under our long-term incentive program, comprising one-half of the total target value of the long-term incentive program awards. The Compensation Committee believes that emphasizing performance-based awards in the form of PSUs in the overall equity award mix is closely aligned with market practice, places a strong emphasis on pay-for-performance, and aligns the NEOs’ compensation with long-term stockholder value creation.

For PSUs granted in 2024 (“2024 PSUs”), the Compensation Committee selected a performance goal comprised of a three-year average annual EPS growth rate, which is measured based on our Adjusted Diluted EPS (“3-Year EPS Growth”). The Compensation Committee believes that the 3-Year EPS Growth metric will closely align the potential payout of the 2024 PSUs to the value ultimately realized by our stockholders over a similar time horizon, and complements the financial performance measures used in the annual cash bonus program described under “Annual Bonus” above. The 2024 PSUs will be eligible to become earned and vest between 0% and 200% of target levels based on the achievement of the three-year EPS Growth metric over a three-year performance period from January 1, 2024 through December 31, 2026, as set forth in the table below (with linear interpolation applied between performance levels), subject generally to the NEO’s continued employment with us through the final determination of the satisfaction of the performance goals by the Compensation Committee, expected to occur in early 2027. The Committee believes that these performance targets represent rigorous performance goals based on the Company’s recent historical growth rates, and that if the PSUs are earned at or above target levels, it will result in significant value creation for our stockholders.

Adjusted Diluted EPS Growth Rate |  | Payout Percentage
11% (maximum) |  |  | 200%
7.5% (target) |  |  | 100%
4% (threshold) |  |  | 50%
<4%) (below threshold) |  |  | 0%

42 | SS&C 2025 PROXY STATEMENT

Advisory Vote to Approve Named Executive Officer Compensation

In addition, the ultimate payout of the 2024 PSUs is also subject to a relative TSR performance modifier based on the percentile ranking of our TSR over the three-year performance period relative to that of the companies comprising our compensation benchmarking peer group described under “Competitive Landscape”, as set forth in the table below. Once the achievement of 3-Year EPS Growth is calculated, the relative TSR modifier will then be applied to the 2024 PSU payout level, with the ultimate payout level adjusted upwards or downwards by up to 20% (subject to the maximum 200% payout). No upward modifier will be applied if our absolute TSR is negative for the three-year performance period. The Compensation Committee has incorporated the relative TSR metric as a performance modifier to the PSUs to more directly link the long-term incentive compensation program to our stockholders’ returns. As a result, the use of this relative TSR modifier set at the 55th percentile to enhance rigor will reward the NEOs for sustained market outperformance, as well as regulate payouts for market underperformance, even if the 3-Year EPS Growth metric is achieved at or above-target.

Relative TSR Modifier |  | Modifier %
≥ 80th percentile |  |  | +20%
55th percentile |  |  | 0%
≤ 30th percentile |  |  | -20%

Stock Options

Stock options are a key component of the annual equity award mix, and comprise 25% of the total target value of the long-term incentive program awards. The Compensation Committee continues to believe that stock options play an effective role in linking pay with performance in that our stock price must appreciate following the grant date in order for the options to deliver any value to the NEOs.

The stock options granted in 2024 (“2024 Options”) will vest over a four-year period from the grant date, with 25% vesting on the first anniversary of the grant date and the remaining 75% vesting in equal monthly installments for three years thereafter, subject generally to the NEO’s continued employment with us through each vesting date.

RSUs

The Compensation Committee believes the RSU component of the annual equity award mix under our long-term incentive program promotes executive retention by linking RSU vesting to continuous employment requirements. The RSU component comprises 25% of the total target value of the long-term incentive program awards. While there are no express performance conditions applicable to the RSUs, the RSU awards are inherently performance-based and aligned with stockholder value creation, as the value of the shares ultimately realized by the NEOs on vesting will be directly impacted by our stock price.

The RSUs granted in 2024 (“2024 RSUs”) will vest in equal annual installments on each of the first three anniversaries of the grant date, subject generally to the NEO’s continued employment with us through each vesting date.

Performance-based stock option performance period that concluded in 202 4

In February 2025, the Compensation Committee reviewed our results for the performance period associated with PSOs granted to Messrs. Stone, Kanwar and White in December 2021, which had a 2022 – 2024 performance period (the “December 2021 PSOs”) which are summarized in the table below.

|  | December 2021 PSOs |
Performance period |  | 2022 – 2024 |
Performance metric |  | Average Annual Adjusted Diluted EPS Growth Rate |
Maximum – Growth Rate / Vesting Percentage |  | 10.5% | 200% |
Target – Growth Rate / Vesting Percentage |  | 4.5% | 100% |
Threshold – Growth Rate / Vesting Percentage |  | 2.5% | 75% |
Below Threshold – Growth Rate / Vesting Percentage |  | <2.5% | 0% |
Actual results – Growth Rate / Vesting Percentage |  | 3.04% | 81.76% |

Following the certification of the performance goals by the Compensation Committee, Mr. Stone received 183,960 PSOs, Mr. Kanwar received 143,080 PSOs and Mr. White received 73,584 PSOs.

Equity Grant Practices

We do not have a formal policy with respect to the timing of grants of our equity awards, but the Compensation Committee has historically granted such awards on a predetermined schedule, in the first calendar quarter of each year, at regularly scheduled meetings of the Compensation Committee scheduled approximately one year in advance. From time to time, we also grant equity awards in connection with new hires and promotion, and the timing of such grants are driven by the timing of the hiring or promotion. We do not schedule our equity

SS&C 2025 PROXY STATEMENT | 43

Advisory Vote to Approve Named Executive Officer Compensation

grants in anticipation of the release of material, non-public information (“MNPI”), nor do we time the release of MNPI based upon the grant dates of equity awards. The Compensation Committee does not take MNPI into account when determining the timing and terms of our equity award grants. In the event MNPI becomes known to the Compensation Committee prior to granting an equity award, the Compensation Committee would use its business judgment to determine whether to delay the grant of equity awards.

2025 Executive Compensation Program Changes

The Compensation Committee has not made and does not expect to make significant changes to the executive compensation program design in 2025 compared to 2024. The size, terms and components of base salary, target annual bonus and long-term incentive equity grants are expected to be unchanged in 2025. In connection with its regular annual review of our market competitiveness among our peers in August 2024, the Compensation Committee determined not to make changes to the comparison companies peer group from the 2024 Peer Group.

Benefits

We offer a variety of benefit programs to all eligible employees, including our executive officers. Our executive officers generally are eligible for the same benefits on the same basis as other employees, including medical, dental and vision benefits, life insurance coverage and short-and long-term disability coverage. All eligible employees are also able to contribute to our 401(k) plan and receive matching Company contributions under the plan. In addition, our executive officers are entitled to reimbursement for reasonable business travel and other expenses incurred during the performance of their duties in accordance with our expense reimbursement policy.

No Perquisites

Consistent with our pay for performance philosophy, in 2024 we did not provide our NEOs with perquisites, excise tax gross-ups or supplemental executive retirement benefits.

Employment Agreements and Severance and Change of Control Benefits

Mr. Stone and Mr. Schell are currently the only NEOs with employment agreements or any contractual severance entitlements upon a termination of employment (other than with respect to any “double-trigger” equity acceleration, as described under “Potential Payments upon Termination or Change of Control below). Mr. Stone’s and Mr. Schell’s agreements provide for certain payments and benefits in the event of specified termination of employment scenarios, as described in detail under “Potential Payments Upon Termination or Change of Control” below.

Insider Trading Policy

We maintain a Securities Transaction Policy that governs the purchase, sale and/or other dispositions of our securities applicable to our personnel, including directors, officers, employees and other covered persons. Our Securities Transaction Policy promotes compliance with insider trading laws, rules and regulations, and Nasdaq listing standards. A copy of our Securities Transaction Policy was included as Exhibit 19 to our Form 10-K for the fiscal year ended December 31, 2024 filed with the Securities and Exchange Commission on March 3, 2025.

Stock Ownership Guidelines, Anti-Hedging and Pledging Policy and Clawback Policy

We have adopted executive stock ownership guidelines under which our executive officers are expected to accumulate and retain a meaningful level of ownership in our stock. Under the stock ownership guidelines, executive officers have the following ownership requirements:

•
Chief Executive Officer – 10x base annual salary
•
Other Executive Officers – 2x base annual salary

For purposes of determining compliance with the ownership guidelines, the following shares are counted as being owned:

•
Shares owned by the executive officer, individually or jointly with such person’s spouse;
•
Shares held in a trust established by the executive officer for the benefit of such person and/or his or her family members;
•
Shares underlying any vested deferred stock units held by the executive officer;
•
Shares credited to the executive officer’s 401(k) plan account; and
•
50% of shares underlying unvested of time-based restricted stock or restricted stock unit awards.

In 2024, we revised the stock ownership guidelines so that shares underlying the in-the-money portion of vested, unexercised stock options no longer count toward satisfaction of the ownership thresholds.

44 | SS&C 2025 PROXY STATEMENT

Advisory Vote to Approve Named Executive Officer Compensation

Additionally, shares underlying unvested and unearned performance awards or unvested stock options do not count toward satisfaction of the ownership thresholds. There are no time periods within which an executive officer must attain the applicable stock ownership level. As of December 31, 2024, all of our NEOs were in compliance with our stock ownership guidelines. Our Compensation Committee will continue to review the stock ownership guidelines in 2025 for continued alignment with leading governance practices as part of its ongoing review of our executive compensation program.

We also have adopted an anti-hedging/anti-pledging policy that prohibits our employees and directors from engaging in any transactions that are designed to hedge or speculate on any change in the market value of our common stock.

The Board has adopted two incentive compensation clawback policies. Our first incentive compensation clawback policy is mandated by the Dodd-Frank Act and applies to incentive compensation awarded to our executives based on a financial measure in the event of a financial restatement without regard to fault or misconduct by our executives. Our second incentive compensation clawback policy extends beyond Dodd-Frank Act requirements and applies to all incentive compensation including cash bonuses and time-based vesting awards (in addition to performance based incentive awards and other incentive compensation based on a financial measure) if our executives’ misconduct is a significant contributing factor to the need for a financial restatement. The Compensation Committee continues to review and assess our clawback policies to further align with the interests of the Company and our shareholders.

Risk Assessment and Compensation Practices

The Compensation Committee, with the help of its outside advisors, oversees the review and assessment of any risks arising from our compensation policies and practices and whether any such risks are reasonably likely to have a material adverse effect on our Company. Based on its review of our executive compensation program and pay for performance philosophy, the Compensation Committee has determined that our compensation policies and practices are not reasonably likely to create risks that would have a material adverse effect on our Company.

Accounting and Tax Implications

The accounting and tax treatment of particular forms of compensation do not materially affect our compensation decisions. However, we evaluate the effect of such accounting and tax treatment on an ongoing basis and will make modifications to compensation policies where we deem it appropriate.

For instance, Section 162(m) of the Internal Revenue Code generally disallows a tax deduction for compensation in excess of $1.0 million paid by a public company to its current and former named executive officers.

In the exercise of its business judgment, and in accordance with its compensation philosophy, the Compensation Committee continues to have the flexibility to award compensation that is not tax deductible if it determines that such award is in our stockholders’ best interests.

Report of the Compensation Committee

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K with our management. Based on this review and discussion, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement.

Potential Payments upon Termination or Change of Control

William C. Stone

Our Compensation Committee believes Mr. Stone’s employment agreement continues to be beneficial to the Company in retaining Mr. Stone. Mr. Stone’s agreement entitles Mr. Stone to specified benefits in the event of the termination of employment under certain circumstances. If we terminate Mr. Stone’s employment without cause (as defined below), if Mr. Stone resigns for good reason (as defined below) prior to the end of the term of the employment agreement, or if Mr. Stone receives a notice of non-renewal of the employment term by us, Mr. Stone will be entitled to receive (1) an amount equal to 200% of his base salary and 200% of his average annual bonus, inclusive of stock and restricted stock that he received as a component of such bonus, over the three bonus years preceding the year of termination, (2) accelerated vesting of 50% of his then-unvested options and full vesting of any restricted stock and (3) three years of Company-paid coverage under certain health plans. In the event of Mr. Stone’s death or a termination of Mr. Stone’s employment due to any disability that renders Mr. Stone unable to perform his duties under the agreement for six consecutive months, Mr. Stone or his representative or heirs, as applicable, will be entitled to receive (1) disability or death benefits (as applicable) in accordance with our programs and arrangements, (2) accelerated vesting as set forth above, and (3) a prorated amount of his average bonus for the three bonus years preceding the year of termination.

“Cause” means (a) Mr. Stone’s willful and continuing failure (except where due to physical or mental incapacity) to substantially perform his duties; (b) Mr. Stone’s conviction of, or plea of guilty or nolo contendere to, a felony; (c) the commission by Mr. Stone of an act of fraud or embezzlement against us or any of our subsidiaries as determined in good faith by a two-thirds majority of the Board; or (d) Mr. Stone’s breach of any material provision of the Amended Employment Agreement.

“Good reason” generally means the occurrence of any of the following events without Mr. Stone’s written consent: (a) an adverse change in Mr. Stone’s employment title; (b) a material diminution in Mr. Stone’s employment duties, responsibilities or authority, or the assignment to Mr. Stone of duties that are materially inconsistent with his position; (c) any reduction in Mr. Stone’s base salary, (d) any breach by us of any material provision of the Amended Employment Agreement, the Stockholders Agreement, or any other governing agreement between us and Mr. Stone; (e) a material diminution in Mr. Stone’s reporting line; or (f) a material diminution in our budget over which Mr. Stone retains authority.

Equity awards granted in December 2020 or later to our executive officers only provide for “double-trigger” acceleration in connection with a change in control – i.e. if an executive officer experiences a qualifying termination of employment within twenty-four (24) months of a change in control. Equity awards granted to our executive officers are also subject to accelerated vesting in the event of a termination of employment due to their death or disability (as defined in the applicable stock incentive plan), with time-vesting awards becoming fully vested on such termination, and a pro-rata portion (as defined in the applicable stock incentive plan) of performance-based awards becoming vested on such termination based on the actual achievement level of the performance goals measured as of the date of such termination as determined by the Compensation Committee.

The table below reflects the estimated amount of compensation payable to Mr. Stone in the event of termination of his employment or a change of control (or similar event, as defined in the applicable equity plan). The amounts shown assume that such termination or change of control was effective as of December 31, 2024. The actual amounts to be paid out, if any, will differ from the amounts reflected below and can only be determined at the time of the termination or change of control.

Brian N. Schell

Mr. Schell’s offer letter entitles Mr. Schell to specified benefits in the event of the termination of employment under certain circumstances. If we terminate Mr. Schell’s employment without cause (as defined below), Mr. Schell will be entitled to receive (1) continued payment of his then-current base salary for a period of 12 months following his termination date, (2) any earned but unpaid annual bonus in respect of the fiscal year prior to the year of termination, and (3) a target annual bonus for the year of termination, prorated based on the number of days that he was employed during the year of termination. Mr. Schell is not entitled to any specified benefits in the event of the termination of his employment under circumstances other than termination without cause.

“Cause” means (i) the Company’s determination that Mr. Schell failed to substantially perform his duties (other than any such failure resulting from his disability) which is not remedied within fifteen days after receipt of written notice from the Company or an affiliate, as applicable, specifying such failure; (ii) the Company’s determination that Mr. Schell failed to carry out, or comply with any lawful and reasonable directive of the Company or the Chief Executive Officer of the Company, which is not remedied within fifteen days after receipt of written notice from the Company or any affiliate, as applicable, specifying such failure; (iii) Mr. Schell’s conviction, plea of no contest, plea of nolo contendere, or imposition of unadjudicated probation for any felony or a crime involving moral turpitude; (iv) Mr. Schell's unlawful use (including being under the influence) or possession of illegal drugs on the Company’s or any affiliate’s, as applicable, premises or while performing your duties and responsibilities; or (v) Mr. Schell’s commission of a material act of fraud, embezzlement, misappropriation, willful misconduct or breach of fiduciary duty against the Company or any affiliate, as applicable.

Equity awards granted in December 2020 or later to our executive officers only provide for “double-trigger” acceleration in connection with a change in control – i.e. if an executive officer experiences a qualifying termination of employment within twenty-four (24) months of a change in control. Equity awards granted to our executive officers are also subject to accelerated vesting in the event of a termination of employment due to their death or disability (as defined in the applicable stock incentive plan), with time-vesting awards becoming fully vested on such termination, and a pro-rata portion (as defined in the applicable stock incentive plan) of performance-based awards becoming vested on such termination based on the actual achievement level of the performance goals measured as of the date of such termination as determined by the Compensation Committee.

The table below reflects the estimated amount of compensation payable to Mr. Schell in the event of termination of his employment or a change of control (or similar event, as defined in the applicable stock incentive plan), or in the event of his death or disability resulting in accelerated vesting of his equity awards. The amounts shown assume that such termination or change of control or death or disability was effective as of December 31, 2024. The actual amounts to be paid out, if any, will differ from the amounts reflected below and can only be determined at the time of the termination or change of control.

Other Named Executive Officers

Assuming a termination date of December 31, 2024, none of our named executive officers other than Mr. Stone and Mr. Schell had any arrangement providing for severance payments.

Equity awards granted in December 2020 or later to our executive officers only provide for “double-trigger” acceleration in connection with a change in control – i.e. if an executive officer experiences a qualifying termination of employment within twenty-four (24) months of a change in control. Equity awards granted to our executive officers are also subject to accelerated vesting in the event of a termination of employment due to their death or disability (as defined in the applicable stock incentive plan), with time-vesting awards becoming fully vested on such termination, and a pro-rata portion (as defined in the applicable stock incentive plan) of performance-based awards becoming vested on such termination based on the actual achievement level of the performance goals measured as of the date of such termination as determined by the Compensation Committee.

The table below sets forth, as of December 31, 2024, the unvested stock awards that would have become fully vested upon a change of control and with a qualifying termination following a change of control for Messrs. Kanwar and White, or in the event of death or disability resulting in accelerated vesting of their equity awards.

2024 Pay Ra tio Disclosure

Pay Ratio

In accordance with the requirements of the Pay Ratio Rule, we are providing the following estimated information for 2024:

•
the annual total compensation of our Chief Executive Officer was $25,870,693;
•
the median of the annual total compensation of all our employees (except our Chief Executive Officer) was $67,831; and
•
the ratio of these two amounts was 381 to 1.

SEC rules for identifying the median employee and calculating the pay ratio allow companies to apply various methodologies and apply various assumptions and, as a result, the pay ratio reported by us may not be comparable to the pay ratio reported by other companies. The methodology we used to calculate our median employee is described below.

Methodology for Identifying Our “Median Employee”

Employee Population

To identify our “median employee”, we first determined our total employee population as permitted under the Pay Ratio Rule. We determined that, as of December 31, 2024 (the date we selected for purposes of identifying our median employee), our employee population consisted of approximately 26,800 individuals (of which approximately 42% were located in the United States and 58% were located in jurisdictions outside the United States). Our employee population consisted of our global workforce of full-time and part-time employees, as described in more detail below.

Adjustments to our Employee Population

As permitted by the Pay Ratio Rule, we adjusted our total employee population for purposes of identifying our “median employee” by excluding 1,152 (or 4.3%) of our employees who were located in certain jurisdictions outside of the United States, as follows: 578 employees from Thailand, 196 employees from China; 108 employees from Malaysia; 73 employees from Japan; 67 employees from Romania; 52 employees from Pakistan; 42 employees from Brazil; 16 employees from Mexico, 15 employees from Bulgaria; 3 employees from Turkey and 1 employee from both Indonesia and Saudi Arabia.

After taking into account this adjustment to our employee population, our total adjusted employee population for purposes of determining our “median employee” consisted of approximately 25,700 individuals.

Determining our Median Employee

To identify our “median employee” from our total adjusted employee population, we compared these employees’ base pay. In making this determination, we annualized the compensation of our full-time and part-time employees who were hired in 2024 but did not work for us for the entire fiscal year. We identified our “median employee” using this compensation measure, which was consistently applied to all of our employees included in the calculation.

We did not make any cost-of-living adjustments in identifying our “median employee.”

Our Median Employee

Using the methodologies described above, we determined that our “median employee” was a full-time, salaried employee located in the United States, with base pay in the amount of $60,382.

Determination of Annual Total Compensation of our “Median Employee” and our CEO

Once we identified our “median employee”, we then calculated such employee’s annual total compensation for 2024 using the same methodology we used for purposes of determining the annual total compensation of our NEOs for 2024 (as set forth in the 2024 Summary Compensation Table on page 46 of this proxy statement).

Our CEO’s annual total compensation for 2024 for purposes of the Pay Ratio Rule is equal to the amount reported in the “Total” column in the 2024 Summary Compensation Table.

Due to the redesign of our executive compensation program during 2022, the compensation mix for our NEOs did not reflect a normalized allocation of compensation elements. The only long-term equity incentives granted to our NEOs in 2022 were PSUs granted in respect of bonuses earned for the 2021 fiscal year. We did not otherwise grant annual equity incentives during 2022 to our NEOs. Accordingly, the amounts reported in the Summary Compensation Table for 2022 did not reflect our normalized go-forward annual compensation mix for our NEOs.

These financial measures generally reflect those used internally to measure the Company’s performance and represent key drivers of sustainable stockholder value creation for our Company. We do not consider any one of the above performance measures, taken in isolation, to be the most important financial measure for our executive compensation design. However, for purposes of the table above, we have deemed Adjusted Consolidated EBITDA as our “most important” financial measure used to link our NEO’s compensation with performance because it is a key component of our 2024 annual bonus program and critical indicator of the Company’s growth and financial health used by our investors and stockholders. For more detail on we link these measures with performance of our NEOs, see “Compensation Discussion and Analysis — Design and Structure of Executive Compensation” on page 37 of this proxy statement.

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Audit Committee Ap proval Policies and Procedures

All the services described above were approved by our Audit Committee. The Audit Committee is responsible for the appointment, compensation and oversight of the work performed by the independent registered public accounting firm. The Audit Committee must pre-approve all audit (including audit-related) services and permitted non-audit services provided by the independent registered public accounting firm in accordance with the pre-approval policies and procedures established by the Audit Committee. The Audit Committee annually approves the scope and fee estimates for the quarterly reviews, year-end audit, statutory audits and tax work to be performed by our independent registered public accounting firm for the next fiscal year. With respect to other permitted services, management defines and presents specific projects and categories of service for which the advance approval of the Audit Committee is requested. The Audit Committee pre-approves specific engagements, projects and categories of services on a fiscal year basis, subject to individual project thresholds and annual thresholds. In assessing requests for services by the independent registered public accounting firm, the Audit Committee considers whether such services are consistent with the independent registered public accounting firm’s independence, whether the independent registered public accounting firm is likely to provide the most effective and efficient service based upon their familiarity with us, and whether the service could enhance our ability to manage or control risk or improve audit quality.

Report of the Audit Committee

The Audit Committee has reviewed our audited financial statements for fiscal 2024 and has discussed these financial statements with our management and PwC, our independent registered public accounting firm.

The Audit Committee has also discussed with our independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

Our independent registered public accounting firm also provided the Audit Committee with the written disclosures and the letter from the independent registered public accounting firm required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. The Audit Committee has discussed with the independent registered public accounting firm its independence from us.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2024.

Approval of SS&C
Technologies Holdings, Inc.
Second Amended and Restated 2023 Stock Incentive Plan

We are asking our stockholders to approve a second amendment and restatement of the SS&C Technologies Holdings, Inc. 2023 Stock Incentive Plan (as amended and restated, the “Plan”) to (i) increase the number of shares of common stock reserved for issuance under the Plan by 6,000,000 shares, (ii) extend the term for one additional year and (iii) include certain other changes described below. Our Board of Directors approved the adoption of the Plan on March 31, 2025, subject to approval by our stockholders.

Other than the changes described above, there are no material changes being made to the Plan.

Overview

The grant of equity incentive awards is a key element of our executive and non-employee director compensation programs that helps ensure a continued strong link between the interests of our executives and directors with those of our stockholders. In addition, we actively compete for highly qualified employees in many geographies across many skill sets and our equity program is a key component of our strategy to attract and retain key individuals. As described in the “Compensation Discussion & Analysis” section of this proxy statement, our compensation philosophy focuses on pay for performance, and under our long-term equity incentive program, we deliver a significant portion of our executive officers’ compensation in the form of equity incentive awards, with an emphasis on performance-based awards. Accordingly, the Board believes it is critical to ensure that we have sufficient share capacity under our long-term equity incentive program to continue to make grants of equity incentive awards to our employees and other service providers.

Our stockholders previously approved the Company’s 2023 Stock Incentive Plan (“Original 2023 Plan”) at the annual meeting of the Company’s stockholders held on May 17, 2023, and approved the Amended and Restated 2023 Stock Incentive Plan (“Amended 2023 Plan”) at the annual meeting of the Company’s stockholders held on May 28, 2024. As of February 28, 2025 , approximately 6,479,508 shares of our common stock remained available for issuance pursuant to future grants under the Amended 2023 Plan, representing 2.6% of our issued and outstanding common stock as of that date. The Board has determined that the current share reserve amount would be insufficient to meet our future needs with respect to attracting, motivating, and retaining key executives and employees in a competitive market for talent. Accordingly, we believe that approving the amendment is necessary to allow us to continue to utilize equity awards to retain and attract the services of our executive officers and other key individuals essential to Company’s long-term growth and financial success and to further align their interests with those of our stockholders.

The second amendment and restatement, if approved by stockholders at the 2025 annual meeting, would increase the number of shares available for issuance under the Plan by 6,000,000 shares. The increase in share reserve represents an incremental dilution of approximately 2.4% the shares of the Company outstanding on a fully-diluted basis as of February 28, 2025, and is intended to provide us with sufficient shares for grants to be made over the next year. The Board believes the number of shares underlying the Plan represents a reasonable amount of potential additional equity dilution, and is committed to effectively managing our share reserves for equity compensation while minimizing stockholder dilution. In addition, if approved by stockholders, the term of the Plan will be extended to the tenth anniversary of the date of the stockholders’ approval at the 2025 annual meeting.

In determining the number of shares to be requested for stockholder approval under this Proposal 4, the Board and the Compensation Committee considered the advice of FW Cook, the Compensation Committee’s independent compensation consultant, the Company’s historical annual share usage; the number of shares remaining available under the existing Amended 2023 Plan; the number of outstanding equity awards under the Company’s stock incentive plans, including the SS&C Technologies Holdings, Inc. 2014 Stock Incentive Plan (the “2014 Plan”) and the existing Amended 2023 Plan; and dilution resulting from the approval of the proposed amendment and restatement.

If stockholders do not approve the amendment and restatement, then the Amended 2023 Plan will remain in effect in accordance with its existing terms and we will continue to grant equity incentive awards under the existing Amended 2023 Plan until the earlier of the date on

SS&C 2025 PROXY STATEMENT | 59

Approval of SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

which there ceases to be any shares remaining available for issuance under the existing Amended 2023 Plan or its expiration on May 28, 2034. Following the exhaustion of the remaining share reserve thereunder or the expiration of the existing Amended 2023 Plan, we will be unable to maintain our equity grant practices and our future ability to issue equity-based awards will be limited and, therefore, we will be at significant competitive disadvantage in attracting and retaining talent. We may also be compelled to replace equity incentive awards with cash awards, which may not align the interests of our executives and employees with those of our stockholders as effectively as equity incentive awards.

Compensation and Governance Best Practices

The Plan includes various compensation and governance best practices with some of the key features as follows:

•
No evergreen. The Plan does not contain an “evergreen” feature pursuant to which the shares authorized for issuance under the Plan can be increased automatically without stockholder approval.
•
Conservative share counting provisions. Shares underlying full-value awards count against the number of shares authorized for issuance as 2.5 shares for every one share under an award.
•
No “liberal” share recycling of options or SARs. Shares tendered or withheld to pay the exercise price or tax withholding with respect to options or stock appreciation rights (SARs) may not be re-granted under the Plan. In addition, any shares repurchased with option exercise proceeds may not be re-granted under the Plan.
•
No dividend equivalents on unvested or unearned awards. Any dividend or dividend equivalents with respect to any shares underlying full-value awards will not be paid unless and until the award has vested (and, in the case of any performance awards, only to the extent the performance goal is earned). In addition, no dividend equivalents will be paid with respect to stock options or SARs.
•
No automatic “single-trigger” vesting upon a change in control. Upon a change in control, awards granted under the Plan will not be subject to automatic accelerated vesting (except in the case of our non-employee directors).
•
No “liberal” change in control definition. The change in control definition under the Plan will only be triggered in those instances where an actual change in control occurs.
•
No change in control/280G tax gross-ups. The Plan does not provide for any change in control-related excise tax gross-up payments or “parachute payments,” and as a general business matter, we do not provide for such gross-ups in other arrangements.
•
Limit on non-employee director compensation. The aggregate value of cash and equity-based compensation granted or paid in any calendar year for service as a non-employee director will not exceed (i) $1,000,000 for the year in which the director is first appointed or elected to the Board or (ii) $750,000 for each year of service thereafter.
•
Clawback provisions. Awards granted under the Plan will be subject to any clawback or recoupment arrangements or policies we have in place, including the SS&C Technologies Holdings, Inc. Financial Statement Compensation Recoupment Policy and the SS&C Technologies Holdings, Inc. Misconduct Clawback and Forfeiture Policy.
•
Minimum vesting requirements. Awards granted under the Plan will be subject to at least one year of vesting, subject to certain exceptions described on page 64 below.
•
No repricing of options or SARs. The Plan does not permit the repricing of underwater options or SARs, either directly or indirectly through replacement with new awards or cash buyouts, without stockholder approval.

Stock Options/SARs Granted |  |  | 2,010,367 |  |  |  | 644,492 |  |  |  | 3,162,679 |  |  |  | 1,939,179 |  |

Weighted-Average Basic Common Shares Outstanding |  |  | 246,380,412 |  |  |  | 248,301,620 |  |  |  | 253,973,709 |  |  |  | 249,551,914 |  |
Share Usage Rate |  |  | 2.3 | % |  |  | 0.7 | % |  |  | 2.2 | % |  |  | 1.7 | % |

*
For purposes of the foregoing table, we calculate the share usage rate based on the applicable number of performance-based stock options (“PSOs”) and performance-based full value awards earned during each applicable year. Beginning in the year ended December 31, 2021, the Company began to issue options and restricted stock units (“RSUs”) under the 2014 Plan that vest only upon achieving certain performance targets. For reference:
•
There were 4,818,100 PSOs granted during the year ended December 31, 2021. There were no PSOs granted during the years ended December 31, 2024, 2023 or 2022. There were 530,000 PSOs granted in March 2021 that had a 3-year performance period ending on December 31, 2023. Of the 530,000 options originally granted, 75,000 of those options were cancelled due to the termination of one of the grantees prior to the end of the 3-year performance period. Of the 455,000 remaining outstanding options, 79.22%, or 360,451, of those options vested in 2024 following the achievement of a portion of the performance criteria. The remaining PSOs granted during the year ended December 31, 2021 have completed their performance period and 81.76%, or 2.7 million, of those options vested in February 2025 following the determination of actual performance over the 3-year performance period.
•
There were 275,026, 343,967 and 810,462 performance-based full-value awards granted during the years ended December 31, 2024, 2023 and 2022, respectively. The performance-based full value awards granted during the year ended December 31, 2022 were cancelled in 2024 following the completion of the 2-year performance period as the minimum performance criteria was not met. The performance-based full value awards granted during the years ended December 31, 2024 and 2023 have 3-year performance periods ending in the years ending December 31, 2027 and 2026, respectively.

Overhang as of February 28, 2025

The following table sets forth certain information as of February 28, 2025, unless otherwise noted, with respect to all of the Company’s outstanding equity awards under all plans. The fully-diluted “overhang” assumes that the entire share reserve is granted in stock options/SARs.

As of February 28, 2025, the per-share closing price of our common stock as reported on Nasdaq was $88.80.

Dilution and Expected Duration

Our Board recognizes the impact of dilution on our shareholders and has evaluated this share request carefully in the context of the need to motivate, retain and ensure that our leadership team and key employees are focused on our strategic priorities. The total fully-diluted overhang as of February 28, 2025, assuming that the entire share reserve is granted in stock options or SARs, would be 16.3% and the total fully-diluted overhang, assuming the share reserve is granted in full-value awards only, would be 14.1%. The Company’s historical practice has been to grant a combination of stock options and full-value awards, resulting in potential overhang between these two levels. In this context, fully-diluted overhang is calculated as the sum of grants outstanding and shares available for future awards (numerator) divided by the sum of the numerator

SS&C 2025 PROXY STATEMENT | 61

Approval of SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

and basic common shares outstanding, with all data effective as of February 28, 2025. Our Board believes that the proposed share reserve represents a reasonable amount of potential equity dilution to accommodate our long-term strategic and growth priorities.

We expect that the share reserve under the Plan, if this proposal is approved by our shareholders, will be sufficient for awards for approximately one year. Expectations regarding future share usage could be impacted by a number of factors such as award type mix; hiring and promotion activity at the executive level; the rate at which shares are returned to the Plan’s reserve under permitted addbacks; the future performance of our stock price; the consequences of acquiring other companies; and other factors. While we believe that the assumptions we used are reasonable, future share usage may differ from current expectations.

Summary Description of the Plan

The following is a summary of the material terms of the Plan as approved by the Board. This summary does not purport to be complete and is qualified in its entirety by reference to the complete text of the Plan, a copy of which is attached as Appendix B to this proxy statement.

Purpose

The purpose of the Plan is to advance the interests of the Company’s stockholders by enhancing the ability of the Company and its affiliates to attract, retain and motivate persons who are expected to make important contributions and by providing such persons with equity ownership opportunities that are intended to better align the interests of such persons with those of the Company’s stockholders.

Eligibility to Receive Awards

Employees (including officers), non-employee directors, consultants and advisors of the Company, its parent and subsidiary corporations and other business ventures in which the Company has a controlling interest are eligible to be granted awards under the Plan.

As of March 25, 2025, there were approximately 27,000 employees and consultants and 8 non-employee directors eligible to participate. The basis for participation in the Plan is the Compensation Committee’s (or its authorized delegate’s) decision, in its sole discretion, that an award to an eligible participant will further the Plan’s purposes as described above. In exercising its discretion, the Compensation Committee (or its delegate) will consider the recommendations of management and the purposes of the Plan.

In addition, holders of equity compensation awards granted by a company that is acquired by the Company or with which the Company combines will be eligible for grants of substitute awards under the Plan to the extent permitted under applicable stock exchange regulations (“substitute awards”).

Administration

The Plan is administered by the Board, which has delegated its administrative powers under the plan to the Compensation Committee. The Compensation Committee: (1) has authority to grant awards and determine the terms and conditions of any awards; (2) has authority to adopt, amend and repeal such administrative rules, guidelines and practices relating to the plan as it deems advisable; (3) may construe and interpret the terms of the Plan and any award agreement thereunder and make all determinations necessary or advisable in administering the Plan and award agreements; and (4) may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any award agreement. All actions and decisions by the Compensation Committee with respect to the plan and any awards are made in its sole discretion and are final and binding on all persons having or claiming any interest in the Plan or in any award. To the extent permitted by applicable law, the Board or the Compensation Committee may delegate to one or more officers of the Company the power to grant Awards (except that no officer may grant awards to any officer or non-employee-director of the Company).

Number of Shares Available for Awards

Subject to certain adjustment events set forth in the Plan (and except for substitute awards), the aggregate maximum number of shares authorized for issuance pursuant to awards will equal the sum of (i) 20,100,000 shares (which includes (x) the existing reserve of 14,100,000 shares under the Amended 2023 Plan) and (y) an increase of 6,000,000 shares, as approved by the Board, subject to approval by the Company’s stockholders, and (ii) the total number of shares that remained available for issuance under the 2014 Plan as of the date of approval of the Original 2023 Plan by the Company’s stockholders on May 17, 2023. As of February 28, 2025, approximately 6,479,508 shares remained available for issuance under the Amended 2023 Plan.

If any award under the Plan or the 2014 Plan expires, terminates or is otherwise surrendered, cancelled, forfeited or terminated without the delivery of shares, the unused shares covered by such Award will again be available for grant pursuant to the ratio described below. In addition, any shares subject to an award under the Plan or the 2014 Plan that is a full-value award that are delivered to or withheld by the Company to satisfy tax withholding obligations will again be available for issuance under the Plan. Any shares under an award under the Plan or the 2014 Plan that are (i) tendered or withheld in payment of an option or SAR’s exercise or reference price, (ii) covered by a stock-settled SAR that are not issued upon settlement of the SAR, (iii) delivered to or withheld by the Company to satisfy tax withholding obligations with respect to options or

62 | SS&C 2025 PROXY STATEMENT

Approval of SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

SARs, or (iv) reacquired by the Company on the open market or otherwise using cash proceeds from the exercise of options, will not be added back to the number of shares available for issuance.

For purposes of the number of shares reserved for issuance under the Plan, including the share recycling provisions described above, each share issued pursuant to a full-value award will count as 2.5 shares for every one share underlying such award and each share issued pursuant to an option or SAR will count as one share for every one share underlying such award.

Shares underlying substitute awards and shares remaining available for grant under a plan of an acquired company or of a company with which the Company combines, appropriately adjusted to reflect the acquisition or combination transaction, will not reduce the number of shares remaining available for issuance under the Plan.

Award Limits

The maximum number of shares that may be issued pursuant to incentive stock options (“ISOs”) is 20,100,000.

A participant who is a non-employee director may not receive compensation for service on the Board, including cash payments and awards granted under the Plan, for any calendar year in excess of (i) $1,000,000 for such director’s year of appointment or election to the Board or (ii) $750,000 for each year thereafter.

Types of Awards

The Plan provides for the grant of stock options, SARs, restricted stock, RSUs, performance awards, and other stock-based awards. Options and SARs may not be granted at an exercise or reference price (as applicable) which is less than the fair market value per share on the grant date (except with respect to substitute awards) and may not be granted for a term in excess of ten years. In accordance with tax rules, ISOs may only be granted to employees.

•
Incentive Stock Options and Nonqualified Stock Options. An option is the right to purchase a specified number of shares of common stock at a specified exercise price, subject to other terms and conditions as are specified in connection with the option grant.
•
Stock Appreciation Rights. A SAR entitles the holder, upon exercise, to receive an amount of common stock, cash or a combination thereof (as determined by the Board) determined by reference to appreciation, from and after the grant date, in the fair market value of a share of common stock over the specified reference price, subject to other terms and conditions as are specified in connection with the SAR grant.
•
Restricted Stock. Restricted stock represents on award of shares that is subject to restrictions on transferability and subject to forfeiture on terms set at the time of grant.
•
Restricted Stock Units. RSUs represent the right to receive shares of common stock (or an equivalent value in cash or other property, as specified in the award certificate) at a designated time in the future.
•
Performance Awards. Performance awards may be payable in cash or stock upon the attainment of specified performance goals.
•
Other Stock-Based Awards. Other stock-based awards may be granted in the discretion of the Compensation Committee subject to the terms of the Plan.

No Repricing

Unless approved by the Company’s stockholders, the Company may not (i) amend any outstanding stock option, SAR or similar stock-based award to provide an exercise or reference price that is lower than the then-current exercise or reference price per share, (ii) cancel any outstanding stock option, SAR or similar stock-based award and grant in substitution of such award new awards covering the same or a different number of shares and having an exercise or reference price per share lower than the then-current exercise or reference price per share of such cancelled Award; (iii) cancel in exchange for a cash payment any outstanding stock option, SAR or similar stock-based award with an exercise or reference price per share above the then-current fair market value or (iv) take any other action under the Plan that constitutes a “repricing” within the meaning of the Nasdaq rules.

Dividends and Dividend Equivalents

Unless provided otherwise in any award agreement, the recipient of a restricted stock award, RSU or performance award may, if so determined by the Compensation Committee, be eligible to receive cash, stock or other property dividends in amounts equivalent to cash, stock or other property dividends on shares with respect to the number of shares covered by the award. Any such amounts will be subject to the same vesting or performance conditions as the underlying award. Accordingly, with respect to any award subject to any service-based or performance-based vesting conditions, the associated dividends or dividend equivalents will not be paid unless and until (and to the same extent) the relevant vesting conditions have been satisfied. In addition, the Compensation Committee may provide that such amounts will be deemed to have been reinvested in additional shares or otherwise reinvested. In no event will dividend equivalents be paid with respect to options or SARs.

SS&C 2025 PROXY STATEMENT | 63

Approval of SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

Performance Goals

The Compensation Committee may establish objectively determinable performance goals for a performance award based on one or more business criteria approved by stockholders. The business criteria may be expressed in terms of Company-wide objectives or in terms of objectives that relate to the performance of an affiliate or a division, business segment or business unit of the Company, and may be based upon relative or comparative performance. Additionally, the Compensation Committee may provide for the inclusion or exclusion of specified circumstances or events in the evaluation of performance.

Minimum Vesting Requirement

Awards granted under the Plan will vest no earlier than the first anniversary of the grant date of the award, except in the case of (i) substitute awards, (ii) shares delivered in lieu of fully vested cash obligations, (iii) awards to non-employee directors that vest on the earlier of the one-year anniversary of the grant date of such award and the next annual meeting of stockholders which is at least 50 weeks after the immediately preceding year’s annual meeting, and (iv) any additional awards up to a maximum of five percent (5%) of the share pool. This restriction also does not apply to accelerated vesting of awards under the Plan in connection with a termination of employment due to death or disability or to the Compensation Committee’s discretion to provide for accelerated exercisability or vesting of any award as permitted under the Plan.

Transferability of Awards

Except as the Board may otherwise permit with respect to certain transfers in accordance with limitations specified in the Plan, awards may not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution or other limited circumstances. In no event may an award be transferred to a third party for financial consideration.

Changes in Capitalization

The Company is required to make equitable adjustments (if necessary to prevent dilution or enlargement of the benefits or potential benefits to be provided under the Plan) to the number of type of securities available under the Plan, the share counting rules and sub-limits specified under the Plan and the number and type of securities and, if applicable, exercise or reference price per share of each outstanding award in the manner determined by the Compensation Committee, in the event of any dividend or distribution (other than an ordinary dividend or distribution) stock splits, recapitalizations, combinations of shares, reclassifications of shares, spin-offs, reorganization, mergers, consolidations, repurchase or exchange of securities and other similar corporate transactions or changes in capitalization or events affecting shares.

Effect of a Change in Control

In the event of a “change in control” (as defined in the Plan and described below), the Compensation Committee may, in its sole discretion take any one or more of the following actions with respect to outstanding awards (unless otherwise specified in an award agreement):

•
continuation or assumption of the award by the successor or surviving corporation (or its parent);
•
substitution or replacement of the award by the successor or surviving corporation (or its parent) with cash, securities, rights or other property to be paid or issued, as the case may be, by the successor or surviving corporation (or a parent or subsidiary thereof) with substantially the same terms and value as the award (including any applicable performance targets or criteria);
•
acceleration of the vesting of the award and the lapse of any restrictions thereon, and in the case of options and SARs, acceleration of the right to exercise the award during a specified period (and the termination of such option or SAR award without payment of any consideration therefor to the extent the award is not timely exercised), in each case, either (i) in the case of an award held by an non-employee director only, immediately prior to or as of the date of the change in control, (ii) upon a participant’s involuntary termination of employment or service (including a termination of employment or service by us without “cause” or by the participant for “good reason” and/or due to the participant’s death or “disability”) on or within a specified period following such change in control or (iii) upon the failure of the successor or surviving corporation (or its parent) to continue or assume the award;
•
in the case of a performance award, determination of the level of attainment of any applicable performance conditions; and
•
cancellation of the award in consideration of a payment equal to the value of the award (as determined in the discretion of the Compensation Committee), with the form, amount and timing of such payment determined by the Compensation Committee in its sole discretion (subject to the terms of the Plan), provided that the Compensation Committee may, in its sole discretion, terminate without the payment of any consideration, any options or SARs for which the exercise or hurdle price is equal to or exceeds the per share value of the consideration to be paid in the change in control transaction.

64 | SS&C 2025 PROXY STATEMENT

Approval of SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

Under the Plan, a “change in control” generally means the occurrence of one or more of the following events:

•
any person or entity is (or becomes, during any 12-month period) the beneficial owner of more than 40% of the total voting power of our stock;
•
the replacement of at least 50% of our directors during any 12-month period;
•
the consummation of our merger or consolidation with any other entity, or the issuance of voting securities in connection with our merger or consolidation with any other entity (unless (i) our voting securities outstanding immediately before such transaction continue to represent more than 50% of the voting power and total fair market value of the stock of the successor or surviving corporation (or its parent) or (ii) the merger or consolidation is effected to implement a recapitalization (or similar transaction) and no person or entity is or becomes the beneficial owner of more than 50% of either our then-outstanding shares or the combined voting power and total fair market value of our then-outstanding voting securities); or
•
the sale or disposition of all or substantially all of our assets to any person or entity during any 12-month period.

Effect of Termination of Service

Except as may otherwise be provided in an award agreement or permitted under the Plan, if a participant’s employment or service is terminated for any reason, any award that is unvested will terminate on the date of such termination of employment or service and any option or SAR award that is vested will remain exercisable for 90 days after the termination date (subject to earlier expiration of the term). Notwithstanding the foregoing, in the event of a participant’s termination of employment or service due to death or Disability (as defined in the Plan): (a) all outstanding and unvested restricted stock awards, restricted stock unit awards, and stock option awards that are subject only to time-based vesting conditions will, subject to the other terms and conditions of the applicable award agreements, become vested; and (b) a pro-rata portion of outstanding and unvested performance awards (including performance stock units and performance stock options) will become vested subject to the other terms and conditions of the applicable award agreements and provided that any applicable performance goals will be deemed achieved based on the actual level of performance of such performance goals as of the date of such termination of service, as determined by the Compensation Committee in its sole discretion.

Authorization of Sub-Plans for Grants to Non-U.S. Employees

The Compensation Committee may establish one or more sub-plans under the Plan to satisfy applicable securities, tax or other laws of various jurisdictions, by adopting supplements to the Plan containing any limitations on the Compensation Committee’s discretion and any additional terms and conditions not inconsistent with the Plan as the Compensation Committee deems necessary or desirable with respect to participants in the applicable jurisdiction.

Clawback

The Compensation Committee has full authority to implement any policies and procedures from time to time, including as necessary to comply with applicable law and stock exchange rules. Any awards granted under the Plan will be subject to any such clawback or recoupment arrangements or policies of the Company in place from time to time, including the cancellation or reimbursement of any awards granted, shares issued or cash received upon the vesting, exercise or settlement of any awards granted or the sale of shares underlying such awards.

Amendment or Termination

The Compensation Committee may at any time amend, suspend or terminate the Plan; however, no amendment requiring stockholder approval under applicable legal, regulatory or listing requirements will become effective until such stockholder approval is obtained.

Effectiveness and Term

The Plan will become effective upon the date of approval by the Company’s stockholders at the 2025 annual meeting. Awards may be granted under the Plan at any time prior to the tenth anniversary of the date of approval of the amendment and restatement by the Company’s stockholders at the 2025 annual meeting, unless the Board earlier terminates the Plan or the maximum number of shares available for issuance has been issued. Awards granted prior to such termination date will remain outstanding in accordance with their terms (including the administration, adjustment, and amendment provisions).

Federal Income Tax Consequences

The following is a summary of the United States federal income tax consequences that generally arise with respect to Awards, based on the federal tax laws in effect as of the date of this proxy statement. This summary is not intended to constitute (and is not) tax advice, and assumes that all Awards are exempt from, or comply with, the rules under Section 409A of the Code regarding nonqualified deferred compensation. Changes to tax laws could alter the consequences described below, and participants are urged to consult their tax advisors regarding their specific circumstances.

SS&C 2025 PROXY STATEMENT | 65

Approval of SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

Incentive Stock Options

A participant will not recognize ordinary income tax upon an ISO’s grant. Also, except as described below, a participant will not recognize ordinary income tax upon an ISO’s exercise if the participant has been employed by the Company or its corporate parent or 50% or more-owned corporate subsidiary at all times beginning with the option grant date and ending three months before the exercise. If the participant has not been so employed during that time, then the participant will be taxed as described below under “Nonqualified Stock Options.” An ISO’s exercise may subject the participant to the alternative minimum tax.

A participant will recognize ordinary income tax upon the sale of the shares acquired upon exercise of an ISO at a profit (if sales proceeds exceed the exercise price). If a participant sells the shares more than two years after the option’s grant and more than one year after its exercise, then all of the profit will be subject to long-term capital gains tax. If a participant sells the shares prior to satisfying these holding periods, then the participant will have engaged in a disqualifying disposition for purposes of Section 422 of the Code and the profit of the amount at which the shares are sole over the exercise price will be subject to ordinary income tax (and the Company may be entitled to a federal income tax deduction with respect to such income). Any additional gain recognized upon the sale will be treated as capital gain for which the Company will not be entitled to a deduction (the gain will be treated as long term if the participant has held the shares for more than one year and otherwise will be treated as short term). If a participant sells the shares at a price that is less than the exercise price, then the loss will be treated as a capital loss for which the Company will not be entitled to a deduction (the loss will be treated as long term if the participant held the shares for more than one year and otherwise will be treated as short term).

Nonqualified Stock Options

A participant will not recognize ordinary income tax upon a nonqualified stock option’s grant. A participant will recognize compensation income upon a nonqualified stock option’s exercise equal to the value of the shares on the exercise date less the exercise price. Upon sale of the shares, the participant will have capital gain or loss equal to the difference between the sales proceeds and the value of the shares on the exercise date. This capital gain or loss will be treated as long term if the participant has held the stock for more than one year and otherwise will be treated as short term. The Company generally will be entitled to a federal income tax deduction with respect to the participant’s compensation income.

Stock Appreciation Rights

A participant will not recognize ordinary income tax upon a SAR’s grant. A participant will recognize ordinary income tax upon the SAR’s exercise equal to the value of cash and/or the fair market value (measured on the exercise date) of the shares received by the participant. This amount will be subject to income tax withholding. The Company generally will be entitled to a federal income tax deduction with respect to the participant’s compensation income.

Restricted Stock

Unless a participant makes an election to accelerate recognition of the income to the date of grant as described below, a participant will not recognize ordinary income tax, and the Company will not be allowed a tax deduction, at the time a restricted stock award is granted, provided that the award is nontransferable or is subject to a substantial risk of forfeiture. When the restrictions lapse, the participant will recognize ordinary income tax equal to the fair market value of the shares as of that date (less any amount he or she paid for the stock), and the Company will be allowed a corresponding federal income tax deduction at that time. If the participant files an election under Section 83(b) of the Code within 30 days after the date of grant of the restricted stock, he or she will recognize ordinary income tax as of the date of grant equal to the fair market value of the shares as of that date (less any amount paid for the stock), and the Company will be allowed a corresponding federal income tax deduction at that time. Any future appreciation in the stock will be taxable to the participant at capital gains rates. However, if the stock is later forfeited, the participant will not be able to recover the tax previously paid pursuant to the election under Section 83(b).

Restricted Stock Units

A participant will not recognize ordinary income tax, and the Company will not be allowed a tax deduction, at the time a restricted stock unit award is granted. Upon receipt of shares of stock (or the equivalent value in cash or other property) in settlement of a restricted stock unit award, a participant will recognize ordinary income tax equal to the fair market value of the shares or other property as of that date (less any amount he or she paid for the stock or property), and the Company will be allowed a corresponding federal income tax deduction at that time.

New Plan Benefits

Grants under the Plan, if any, will be subject to the Compensation Committee’s discretion. Therefore, we cannot determine the number or type of awards that will be granted to any participant under the Plan for 2025 or any other year, and no information is provided concerning the benefits to be delivered under the Plan to any individual or group of individuals. Information regarding our recent practices with respect to equity-based compensation is presented elsewhere in this proxy statement.

SS&C 2025 PROXY STATEMENT | 67

Ownership of Our Common Stock

This table presents information concerning the beneficial ownership of the shares of our common stock as of March 25, 2025. Specifically, the table reflects beneficial ownership information about:

•
each person we know to be the beneficial owner of more than 5% of the outstanding shares of our common stock;
•
each of our directors and named executive officers; and
•
all of our directors and executive officers as a group.

Beneficial ownership is determined under the rules of the SEC and generally includes voting or investment power over securities. Except in cases where community property laws apply or as indicated in the footnotes to this table, we believe that each stockholder identified in the table possesses sole voting and investment power over all shares of common stock shown as beneficially owned by our stockholder. Shares of common stock subject to stock options and RSUs that become exercisable or vest within 60 days of March 25, 2025 are considered outstanding and beneficially owned by the person holding the options and RSUs for the purpose of computing the percentage ownership of that person but are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of the persons and entities listed on the table is c/o SS&C Technologies Holdings, Inc., 80 Lamberton Road, Windsor, CT 06095.

Based on a review of these reports, we believe that during fiscal 2024, all reports required by Section 16(a) to be filed by these persons were filed on a timely basis.

Submitting a proxy or voting instructions in advance will not prevent you from attending the 2025 annual meeting virtually and voting electronically, if you so desire. If you received a printed copy of our proxy materials, a postage-paid, return-addressed envelope is enclosed for your convenience.

Voting P rocedures

If you are not the stockholder of record and hold shares through a bank, broker or other nominee, such agent may have special voting instructions that you should follow. You should contact your bank, broker or other nominee to obtain instructions for voting your shares.

Whether or not you expect to attend the 2025 annual meeting virtually, you are requested to complete, sign, date and return the enclosed form of proxy (or, if you are a stockholder accessing these proxy materials via the internet, you are requested to vote by following the instructions for voting provided in the Notice). The shares represented by your proxy will be voted in accordance with your instructions. If you attend the 2025 annual meeting, you may vote by ballot.

Your properly completed proxy card will appoint William C. Stone, Brian N. Schell and Jason White as proxy holders, or your representatives, to vote your shares in the manner directed therein by you. Mr. Stone is our Chairman and Chief Executive Officer, Mr. Schell is our Executive Vice President and Chief Financial Officer and Mr. White is our Senior Vice President, General Counsel and Secretary. Your proxy permits you to direct the proxy holders to:

General Information About the 2024 Annual Meeting

Revocation of Proxies

You may revoke your proxy at any time before it is exercised by (1) delivering to us a signed proxy card with a date later than the date of your previously delivered proxy, (2) voting electronically at the 2025 annual meeting, (3) changing your vote or revoking your proxy over the internet, or (4) sending a written revocation to our Corporate Secretary at our principal executive offices. Shares represented by valid proxies that are received prior to the 2025 annual meeting and not revoked at or prior to the 2025 annual meeting will be voted at the 2025 annual meeting.

Stockholders E ntitled to Vote

The Board has fixed March 25, 2025 as the record date for the 2025 annual meeting. You are entitled to vote (electronically or by proxy) at the 2025 annual meeting if you were a stockholder of record on the record date. On the record date, we had 246,406,279 shares of common stock outstanding (each of which entitles its holder to one vote). Holders of shares of our common stock do not have cumulative voting rights.

Quo rum

For all proposals on the agenda for the 2025 annual meeting, the holders of a majority of the shares of common stock issued and outstanding and entitled to vote must be present at the 2025 annual meeting in person or represented by proxy to constitute a quorum. Shares represented by all proxies received, including proxies that abstain from voting on a proposal, as well as broker non-votes (as described below), will be counted toward establishing a quorum.

Votes R equired

For all proposals, the affirmative vote of the holders of a majority in voting power of the votes cast by holders of all of the shares of common stock present in person or represented by proxy will be required for approval. Shares that abstain and broker non-votes will not be counted as votes in favor of any proposal and will also not be counted as votes cast. Accordingly, abstentions and broker non-votes will have no effect on the outcome of any proposal.

If you hold shares of common stock through a bank, broker or other nominee, that party may under certain circumstances vote your shares if you do not timely provide them with voting instructions. Banks, brokers or other nominees have discretionary authority to vote customers’ unvoted shares on routine matters. Your bank, broker or other nominee cannot vote your shares on any matter that is not considered a routine matter. Only Proposal 3, ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal 2025, is considered a routine matter. Shares for which a bank, broker or other nominee cannot vote on a particular matter because that party does not have discretionary voting authority to do so are considered “broker non-votes” on these matters.

Solicitation of Proxies

We will bear the expenses of preparing, printing and assembling the materials used in the solicitation of proxies. In addition to the solicitation of proxies by use of the mail or the Internet, we may also use the services of some of our officers and employees (who will receive no compensation for such services in addition to their regular salaries) to solicit proxies personally and by telephone and email. Banks, brokers or other nominees will be requested to forward solicitation materials to the beneficial owners of shares of record held by them, and we will reimburse them for their reasonable expenses.

How We Use Notice & Access

We will distribute proxy materials to our stockholders over the Internet by sending them a Notice of Internet Availability (“Notice”), that explains how to access our proxy materials and vote online. Stockholders’ access to our proxy materials via the Internet allows us to reduce printing and delivery costs and lessen adverse environmental impacts. If you received a Notice and would like us to send you a printed copy of our proxy materials, please follow the instructions included in your Notice or visit the applicable online voting website and request printed materials to be mailed at no cost to you.

This proxy statement and our Annual Report to Stockholders on Form 10-K for the fiscal year ended December 31, 2024 are available for viewing, printing and downloading at http://www.ssctech.com/2025annualmeeting. This proxy statement and our Annual Report to Stockholders on Form 10-K for the fiscal year ended December 31, 2024 are also available on the SEC’s website at http://www.sec.gov.

Stockholder Proposals and Director Nominations

For 2026 Annual Meeting

Proposals of stockholders intended to be presented at the 2026 annual meeting of stockholders pursuant to Rule 14a-8 under the Exchange Act must be received by us no later than December 4, 2025 in order to be included in the proxy statement and form of proxy relating to that meeting. Proposals should be sent by mail at SS&C Technologies Holdings, Inc., Attention: Corporate Secretary, 80 Lamberton Road, Windsor, CT 06095, or by email to CorpLegal@sscinc.com, SS&C Technologies Holdings, Inc., Attention: Corporate Secretary.

Stockholders who wish to submit a “proxy access” nomination for inclusion in our proxy statement in connection with our 2026 annual meeting of stockholders may do so by submitting a nomination notice to our Corporate Secretary at our principal executive offices in compliance with the procedures and along with the other information required by our Bylaws, no earlier than November 4, 2025 and no later than December 4, 2025.

In addition, our Bylaws provide for an advance notice procedure for director nominations and stockholder proposals that are not submitted for inclusion in our proxy statement but that a stockholder instead wishes to present at an annual meeting. The required notice must be delivered by the stockholder and received by our Corporate Secretary at our principal executive offices no earlier than January 21, 2026 and no later than February 20, 2026 and must comply with the additional requirements of our Bylaws.

Householding of Proxies

The SEC has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for annual reports and proxy statements with respect to two or more stockholders sharing the same address by delivering a single annual report and/or proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies. We and some brokers household annual reports and proxy materials, delivering a single annual report and/or proxy statement to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders.

Once you have received notice from your broker or us that they or we will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent.

If, at any time, (1) you no longer wish to participate in householding and would prefer to receive a separate annual report and/or proxy statement in the future or (2) you and another stockholder sharing the same address wish to participate in householding and prefer to receive a single copy of our annual report and/or proxy statement, please notify your broker if your shares are held in a brokerage account or us if you hold registered shares. You can notify us by sending a written request via email to investorrelations@sscinc.com, SS&C Technologies Holdings, Inc., or by calling 212-367-4705.

Non-GAAP Financial Measures

Non-GAAP R econciliations

Adjusted revenues, total 2024 annual bonus program revenues and organic revenue growth are key metrics used in determining annual bonuses for executive officers. Adjusted revenues represent revenues adjusted to include a) amounts that would have been recognized if deferred revenue were not adjusted to fair value at the date of acquisition and b) amounts that would have been recognized if not for adjustments to deferred revenue and retained earnings related to the adoption of ASC 606. Total 2024 annual bonus program revenues are further adjusted to exclude the favorable or unfavorable impact of foreign exchange rates on revenues earned in 2024 based on the difference between foreign exchange rates used in the development of our 2024 revenue target and actual foreign exchange rates in place during the year ended December 31, 2024. During the year ended December 31, 2024, foreign exchange rates were favorable compared to rates used in establishing the 2024 revenue target and therefore an adjustment was made to decrease 2024 annual bonus program revenues. Organic revenue growth compares the year-over-year revenue change after excluding the impact of acquisitions and foreign exchange.

Appendix A: Non-GAAP Financial Measures

Adjusted Consolidated EBITDA and Adjusted Consolidated EBITDA adjusted for foreign exchange movements are key metrics used in determining annual bonuses for executive officers. Adjusted Consolidated EBITDA is a non-GAAP financial measure used in key financial covenants contained in our senior credit facilities, which are material facilities supporting our capital structure and providing liquidity to our business. Adjusted Consolidated EBITDA is defined as earnings before interest, taxes, depreciation and amortization (EBITDA), and further adjusted to exclude stock compensation expense, unusual items and other adjustments permitted in calculating covenant compliance under the senior credit facilities, excluding acquired EBITDA. Adjusted Consolidated EBITDA does not represent net income or cash flow from operations as those terms are defined by GAAP and does not necessarily indicate whether cash flows will be sufficient to fund cash needs. The following is a reconciliation of net income to Adjusted Consolidated EBITDA and Adjusted Consolidated EBITDA adjusted for foreign exchange movements.

SS&C 2025 PROXY STATEMENT | 75

Appendix A: Non-GAAP Financial Measures

Adjusted net income and adjusted diluted earnings per share attributable to SS&C represent net income and earnings per share attributable to SS&C before amortization of intangible assets and deferred financing costs, stock-based compensation, purchase accounting adjustments and other items. Adjusted net income and adjusted diluted earnings per share attributable to SS&C are considered to be important to management and investors because they represent our operational performance exclusive of the effects of amortization of intangible assets and deferred financing costs, stock-based compensation, purchase accounting adjustments, loss on extinguishment of debt and other items, that are not operational in nature or comparable to those of our competitors.

Adjusted net income and adjusted diluted earnings per share are not recognized terms under GAAP. Adjusted net income and adjusted diluted earnings per share do not represent net income or diluted earnings per share, as those terms are defined under GAAP, and should not be considered as alternatives to net income or diluted earnings per share as indicators of our operating performance. Adjusted net income and adjusted diluted earnings per share attributable to SS&C as presented herein are not necessarily comparable to similarly titled measures presented by other companies. Below is a reconciliation of adjusted net income and adjusted diluted earnings per share attributable to SS&C to net income and diluted earnings per share attributable to SS&C, the GAAP measures we believe to be most directly comparable to adjusted net income and adjusted diluted earnings per share.

1.
Purpose

The purpose of this Second Amended and Restated 2023 Stock Incentive Plan (as amended or amended and restated from time to time, the “Plan”) of SS&C Technologies Holdings, Inc., a Delaware corporation (the “Company”), is to advance the interests of the Company’s stockholders by enhancing the ability of the Company and Company Affiliates to attract, retain and motivate persons who are expected to make important contributions and by providing such persons with equity ownership opportunities that are intended to better align the interests of such persons with those of the Company’s stockholders. Certain terms used herein are defined in Section ‎11 of the Plan.

The Company’s 2023 Stock Incentive Plan was originally adopted by the Company’s stockholders on May 17, 2023 (the “Original Adoption Date”), and the Amended and Restated 2023 Stock Incentive Plan (“Amended 2023 Plan”) was adopted by the Company’s stockholders on May 28, 2024. Upon the Original Adoption Date, (i) the 2023 Stock Incentive Plan superseded and replaced the Company’s Second Amended and Restated 2014 Stock Incentive Plan (the “Prior Plan”) and (ii) no further awards were permitted to be made pursuant to the Prior Plan (provided that, following the Original Adoption Date, any awards previously granted under the Prior Plan that were outstanding as of the Original Adoption Date (collectively, the “Prior Awards”) remain outstanding in accordance with their terms).

The Plan, as amended and restated herein, shall become effective upon the date of approval by the Company’s stockholders at a meeting of Company stockholders duly held in accordance with the Delaware General Corporation Law, or any adjournment thereof in accordance with applicable provisions of the Delaware General Corporation Law (the date of such approval, the “Restatement Effective Date”), such stockholder approval to be obtained not later than one year after the date on which the Plan, as amended and restated herein, is adopted by the Board.

2.
Eligibility

All employees and officers of the Company or a Company Affiliate, as well as non-employee directors of the Company and consultants and advisors to the Company or a Company Affiliate (as the terms consultants and advisors are defined and interpreted for purposes of Form S‑8 under the Securities Act, or any successor form), are eligible to be granted Awards under the Plan. Each person who is granted an Award under the Plan is deemed a “Participant.” The Plan provides for the following types of awards, each of which is referred to as an “Award”: Options, SARs, Restricted Stock Awards, Restricted Stock Unit Awards, Other Share-Based Awards and Performance Awards (each as defined in Section 5 or Section 11, as applicable). Except as otherwise provided by the Plan, each Award may be made alone or in addition or in relation to any other Award. The terms of each Award need not be identical, and Participants need not be treated uniformly under the Plan.

3.
Administration of the Plan

The Plan will be administered by the Board. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to a Committee. The Board and, to the extent such authority has been delegated to it, a Committee: (1) shall have authority to grant Awards and determine the terms and conditions of any Awards; (2) shall have authority to adopt, amend and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem advisable; (3) may construe and interpret the terms of the Plan and any Award Agreement entered into under the Plan and make all determinations necessary or advisable in administering the Plan and Award Agreements; and (4) may correct any defect, supply any omission or reconcile any inconsistency in the Plan or any Award Agreement. The term “Plan Administrator” means, as applicable, the Board or a Committee. All actions and decisions by the Plan Administrator with respect to the Plan and any Awards shall be made in its sole discretion and shall be final and binding on all persons having or claiming any interest in the Plan or in any Award. By accepting any Award, each Participant acknowledges and agrees that all actions and decisions of the Plan Administrator are final, binding and conclusive. To the extent permitted by applicable law, the Board or the Committee may delegate to one or more officers of the Company the power to grant Awards hereunder; provided that no officer shall be authorized to grant Awards to any “executive officer” of the Company (as

defined by Rule 3b-7 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) or to any “officer” of the Company (as defined by Rule 16a-1 under the Exchange Act) or to any non-employee director of the Company.

Stock Available for Awards
(a)
Number of Shares; Share Counting.

(1) Authorized Number of Shares. As of the Restatement Effective Date and subject to adjustment under Section ‎8, the maximum number of Shares available for issuance pursuant to Awards under the Plan shall equal the sum of (i) 20,100,000 Shares, which includes (x) the existing reserve of 14,100,000 Shares under the Amended 2023 Plan and (y) an increase of 6,000,000 Shares, as approved by the Board, subject to approval by the Company’s stockholders, and (ii) the total number of Shares remaining available for issuance under the Prior Plan as of the Original Adoption Date (clauses (i) and (ii), collectively, the “Share Pool”). Any Shares issued pursuant to (x) an Option or SAR shall be counted against the Share Pool as one (1) Share for every one (1) Share underlying such Option or SAR and (y) an Award other than an Option or SAR (a “Full-Value Award”) shall be counted against the Share Pool as two and one-half (2.5) Shares for every one (1) Share underlying such Full-Value Award. Subject to adjustment under Section ‎8, the maximum number of Shares available for issuance with respect to Incentive Stock Options shall equal 20,100,000 Shares. Shares underlying Substitute Awards and Shares remaining available for grant under a plan of an acquired company or of a company with which the Company combines (whether by way of amalgamation, merger, sale and purchase of shares or other securities or otherwise), appropriately adjusted to reflect the acquisition or combination transaction, shall not reduce the number of Shares remaining available for issuance under the Plan.

(2) Type of Shares. Shares issued under the Plan may consist in whole or in part of authorized but unissued Shares or treasury Shares.

(3) Share Counting. For purposes of counting the authorized number of Shares available for issuance pursuant to Awards under the Plan, from and after the Original Adoption Date:

(A) if any Award or Prior Award expires, terminates or is otherwise surrendered, canceled, cash-settled, forfeited, terminated without the delivery of Shares or repurchased by the Company at its original issuance price pursuant to a contractual repurchase right, the unused Shares covered by such Award shall again be available for the grant of Awards and added back to the Share Pool (i) on a one (1)-for-one (1) basis if such Shares were underlying an Option or SAR under the Plan (or a stock option or stock appreciation right under the Prior Plan) and (ii) one a two and one-half (2.5)-for-one (1) basis if such Shares were underlying a Full-Value Award under the Plan (or an award other than a stock option or stock appreciation right under the Prior Plan (a “Prior Plan Full-Value Award”)); provided, however, that in the case of Incentive Stock Options, the foregoing shall be subject to any limitations under the Code;

(B) Any Shares subject to an Award or Prior Award that is a Full-Value Award or Prior Plan Full-Value Award that are tendered to, or withheld by, the Company for tax withholding thereunder, shall again be, or shall become, available for issuance under the Plan one a two and one-half (2.5)-for-one (1) basis; and

(C) Notwithstanding anything to the contrary, Shares subject to an Award or Prior Award shall not again be available for issuance under the Plan if such Shares are (i) Shares tendered or withheld in payment of the exercise price or reference price of an Option or SAR, (ii) Shares covered by a stock-settled SAR that were not issued upon the settlement of the SAR, (iii) tendered to, or withheld by, the Company for tax withholding under an Option or SAR, or (iv) Shares reacquired by the Company on the open market or otherwise using cash proceeds from the exercise of Options.

(b) Annual Per-Participant Limits for Non-Employee Directors. Notwithstanding any provision to the contrary in the Plan or in any policy of the Company regarding non-employee director compensation, the aggregate value of all compensation granted or paid in any calendar year for service as a non-employee director, including cash payments and Awards (the value of which will be the grant date fair value determined in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto, for the calendar year in which the grant date occurs), shall not exceed (i) $1,000,000 for the year in which the non-employee director is first appointed or elected to the Board or (ii) $750,000 for each year of service on the Board thereafter.

5.
Awards.

(a) Stock Options. The Plan Administrator may grant options to purchase Shares (each, an “Option”) and determine the number of Shares to be covered by each Option. Options may be Incentive Stock Options or Nonqualified Stock Options. Except as set forth in the Plan, the Plan Administrator shall determine the conditions and limitations applicable to the exercise of each Option, including conditions relating to compliance with applicable securities laws, as it considers necessary or advisable. Incentive Stock Options shall only be granted to employees of the Company or any Company Affiliate who are eligible under Section 422 of the Code to receive Incentive Stock Options and Incentive Stock Options shall be subject to and construed consistently with the requirements of Section 422 of the Code. The Company shall have no liability to a Participant, or any other party, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option or if the Company converts an Incentive Stock Option to a Nonqualified Stock Option.

(1) Payment Upon Exercise of Options. Except as may otherwise be provided in the applicable Award Agreement or approved by the Plan Administrator, Shares purchased upon the exercise of an Option granted under the Plan shall be paid for as follows:

SS&C 2025 PROXY STATEMENT | 79

Appendix B: SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

(A) in cash or by check, payable to the order of the Company (or, to the extent provided in the applicable Award Agreement, a Company Affiliate);

(B) by (i) delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding or (ii) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price and any required tax withholding;

(C) by delivery at the time of exercise (either by actual physical delivery or by attestation) of Shares owned by the Participant valued at their Fair Market Value, provided (i) such method of payment is then permitted under applicable law, (ii) such Shares, if acquired directly from the Company or a Company Affiliate, were owned by the Participant for such minimum period of time, if any, as may be established by the Plan Administrator, and (iii) such Shares are not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements;

(D) with respect to a Nonqualified Stock Option, by delivery of a notice of “net exercise,” as a result of which the Participant would receive (i) the number of Shares underlying the portion of the Option being exercised, less (ii) such number of Shares as is equal to (A) the aggregate exercise price for the portion of the Option being exercised divided by (B) the Fair Market Value on the date of exercise;

(E) any combination of the above forms of payment; or

(F) such other lawful consideration as the Plan Administrator may determine.

(2) Award Agreements. The terms of any Option granted under the Plan shall be set forth in an Award Agreement which shall contain provisions determined by the Plan Administrator and not inconsistent with the Plan. The terms of Options need not be the same with respect to each Participant.

(b) Stock Appreciation Rights. The Plan Administrator may grant Awards consisting of stock appreciation rights entitling the holder, upon exercise, to receive an amount of Common Stock or cash or a combination thereof (such form to be determined by the Plan Administrator) determined in whole or in part by reference to appreciation, from and after the date of grant, in the fair market value of a Share over the reference price established pursuant to Section 5(c) (“SARs”). The date as of which such appreciation is determined shall be the exercise date. SARs may be granted in tandem with, or independently of, Options granted under the Plan.

(1) Tandem Awards. When SARs are expressly granted in tandem with Options, (i) the SAR will be exercisable only at such time or times, and to the extent, that the related Option is exercisable and will be exercisable in accordance with the procedure required for exercise of the related Option; (ii) the SAR will terminate and no longer be exercisable upon the termination or exercise of the related Option, except that a SAR granted with respect to less than the full number of shares covered by an Option will not be reduced until the number of shares as to which the related Option has been exercised or has terminated exceeds the number of shares not covered by the SAR; (iii) the Option will terminate and no longer be exercisable upon the exercise of the related SAR; and (iv) the SAR will be transferable only with the related Option.

(2) Independent SARs. A SAR not expressly granted in tandem with an Option will become exercisable at such time or times, and on such conditions, as the Plan Administrator may specify in the Award Agreement for such SAR.

(3) Award Agreements. The terms of any SAR granted under the Plan shall be set forth in an Award Agreement which shall contain provisions determined by the Plan Administrator and not inconsistent with the Plan. The terms of SARs need not be the same with respect to each Participant.

(c) Exercise or Reference Price. The Plan Administrator shall establish the exercise price of each Option or the reference price for each SAR, or the formula by which such exercise price or reference price will be determined. The exercise or reference price shall be specified in the applicable Award Agreement. Except with respect to Substitute Awards, the exercise or reference price shall be not less than 100% of the Fair Market Value of the Common Stock on the date of grant; provided that, for the avoidance of doubt, if the Plan Administrator approves the grant of an Option or SAR with an effective date that is a specified future grant date, the exercise or reference price shall be not less than 100% of the Fair Market Value on such future effective grant date.

(d) Duration. Each Option and SAR shall be exercisable at such times and subject to such terms and conditions as specified in the applicable Award Agreement; provided, however, that no Option or SAR will be granted with a term in excess of 10 years. If an Option or SAR granted under the Plan is set to expire during a period when the exercise of such Option or SAR (or the sale of Shares acquired upon the exercise of such Option or SAR) is prohibited under applicable law or the Company’s insider trading policy, the term of such Option or SAR shall automatically extend until the end of the 30th day following the end of such prohibition; provided, however, that (i) the Intrinsic Value of such Option or SAR is greater than zero as of the original expiration date, (ii) with respect to Options, such Option is not an Incentive Stock Option, and (iii) in no event shall an Option or SAR be exercisable after the 10th anniversary of the date of grant of such Award.

(e) Exercise of Awards. Except as otherwise provided in the applicable Award Agreement, Options and SARs may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic) approved by the Company, together with, for Options, payment in full of the exercise price for the number of Shares for which the Option is exercised (in the manner specified below) and any required tax

80 | SS&C 2025 PROXY STATEMENT

Appendix B: SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

withholding (in the manner specified in Section 9(d). Shares subject to the Option and SAR (if any) will be issued (either in certificated form or the electronic equivalent thereof) as soon as practicable following exercise.

(f) Restricted Stock and Restricted Stock Units. The Plan Administrator may grant Awards of Restricted Stock or Restricted Stock Units to Participants either alone or in addition to other Awards granted under the Plan (a “Restricted Stock Award” or “Restricted Stock Unit Award”, respectively), and such Restricted Stock Awards and Restricted Stock Unit Awards shall also be available as a form of payment of Performance Awards. The Plan Administrator has absolute discretion to determine whether any consideration (other than services) is to be received by the Company or any Company Affiliate as a condition precedent to the issuance of a Restricted Stock Award or Restricted Stock Unit Award.

(1) Award Agreements. The terms of any Restricted Stock Award or Restricted Stock Unit Award granted under the Plan shall be set forth in an Award Agreement which shall contain provisions determined by the Plan Administrator and not inconsistent with the Plan. The terms of Restricted Stock Awards and Restricted Stock Unit Awards need not be the same with respect to each Participant.

(2) Rights of Holders of Restricted Stock and Restricted Stock Units. Unless otherwise provided in the applicable Award Agreement, beginning on the date of grant of a Restricted Stock Award and subject to execution of the applicable Award Agreement, the Participant shall become a stockholder of the Company with respect to all Shares of Restricted Stock subject to the Award Agreement and shall have all of the rights of a stockholder, including the right to vote such Shares. A Participant receiving a Restricted Stock Unit Award shall not possess voting rights with respect to such Award. Holders of Restricted Stock and Restricted Stock Unit Awards may, as determined by the Plan Administrator in its sole discretion, receive dividends or other distributions or cash, stock or other property dividends in amounts equivalent to cash, stock or other property dividends on Shares (“Dividend Equivalents”); provided that any Shares or any other property distributed as a dividend, Dividend Equivalent or otherwise with respect to any Restricted Stock Award or Restricted Stock Unit Award as to which the vesting or other restrictions have not yet lapsed shall be subject to the same restrictions as such Restricted Stock Award or Restricted Stock Unit Award and shall not be paid or otherwise distributed until (and to the same extent) such restrictions lapse or are otherwise satisfied. The Plan Administrator may provide in an Award Agreement that an Award of Restricted Stock is conditioned upon the Participant making or refraining from making an election with respect to the Award under Section 83(b) of the Code. If a Participant makes an election pursuant to Section 83(b) of the Code with respect to an Award of Restricted Stock, the Participant shall be required to file promptly a copy of such election with the Company.

(3) Issuance of Shares. Any Restricted Stock granted under the Plan may be evidenced in such manner as the Plan Administrator may deem appropriate, including book-entry registration or issuance of a stock certificate or certificates, which certificate or certificates shall be held by the Company. Such certificate or certificates shall be registered in the name of the Participant and shall bear an appropriate legend referring to the restrictions applicable to such Restricted Stock.

(g) Other Share-Based Awards. Other Awards of Shares and other Awards that are valued in whole or in part by reference to, or are otherwise based on, Shares or other property (“Other Share-Based Awards”), including deferred stock units, may be granted to Participants either alone or in addition to other Awards granted under the Plan. Other Share-Based Awards shall also be available as a form of payment of other Awards granted under the Plan and other earned cash-based compensation.

(1) Award Agreements. The terms of Other Share-Based Awards granted under the Plan shall be set forth in an Award Agreement which shall contain provisions determined by the Plan Administrator and not inconsistent with the Plan. The terms of such Awards need not be the same with respect to each Participant. Any Shares or any other property distributed as a dividend, Dividend Equivalent or otherwise with respect to any Other Share-Based Award as to which the restrictions have not yet lapsed shall be subject to the same restrictions as such Other Share-Based Award.

(2) Payment. Except as may be provided in an Award Agreement, Other Share-Based Awards may be paid in cash, Shares, other property or any combination thereof, in the sole discretion of the Plan Administrator. Other Share-Based Awards may be paid in a lump sum or in installments or, in accordance with procedures established by the Plan Administrator, on a deferred basis subject to the requirements of Section 409A of the Code.

(h) Performance Awards. Performance Awards in the form of Performance Shares or Performance Units, as determined by the Plan Administrator in its sole discretion, may be granted hereunder to Participants, for no consideration or for such minimum consideration as may be required by applicable law, either alone or in addition to other Awards granted under the Plan. The performance goals to be achieved for each Performance Period shall be conclusively determined by the Plan Administrator and may be based upon the criteria set forth in Section 6(a).

(1) Award Agreements. The terms of any Performance Award granted under the Plan shall be set forth in an Award Agreement which shall contain provisions determined by the Plan Administrator and not inconsistent with the Plan, including whether such Awards shall have dividends or Dividend Equivalents. The terms of Performance Awards need not be the same with respect to each Participant. Any Shares or any other property distributed as a dividend, Dividend Equivalent or otherwise with respect to any Performance Award as to which the restrictions have not yet lapsed shall be subject to the same restrictions (including achievement of applicable performance criteria) as such Performance Award.

(2) Terms and Conditions. The performance criteria to be achieved during any Performance Period and the length of the Performance Period shall be determined by the Plan Administrator upon the grant of each Performance Award. The amount of the Award to be distributed shall be conclusively determined by the Plan Administrator.

(3) Payment. Except as may be provided in an Award Agreement, Performance Awards will be distributed only after the end of the relevant Performance Period. Performance Awards may be paid in cash, Shares, other property or any combination thereof, in the sole discretion

SS&C 2025 PROXY STATEMENT | 81

Appendix B: SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

of the Plan Administrator. Performance Awards may be paid in a lump sum or in installments following the close of the Performance Period or, in accordance with procedures established by the Committee, on a deferred basis subject to the requirements of Section 409A of the Code.

(i) Limitation on Repricing. Unless such action is approved by the Company’s stockholders, the Company may not (except as provided for under Section 8): (1) amend any outstanding Award that is an Option, SAR or similar Other Share-Based Award granted under the Plan to provide an exercise or reference price per Share that is lower than the then-current exercise or reference price per Share of such outstanding Award; (2) cancel any outstanding Option, SAR or similar Other Share-Based Award and grant in substitution therefor new Awards covering the same or a different number of Shares and having an exercise or reference price per Share lower than the then-current exercise or reference price per Share of such cancelled Award; (3) cancel in exchange for a cash payment any outstanding Option, SAR or similar Other Share-Based Award with an exercise or reference price per Share above the then-current Fair Market Value; or (4) take any other action under the Plan that constitutes a “repricing” within the meaning of NASDAQ rules.

(j) No Reload. No Award granted under the Plan shall contain any provision entitling the Participant to the automatic grant of additional Awards in connection with any exercise of the original Award.

(k) Dividend Equivalents. Subject to the provisions of the Plan and any Award Agreement, the recipient of an Award may, if so determined by the Plan Administrator, receive Dividend Equivalents with respect to the number of Shares covered by the Award, as determined by the Plan Administrator, in its sole discretion; provided that, notwithstanding anything to the contrary, any such amounts and Dividend Equivalents shall be subject to the same vesting or performance conditions as the underlying Award and shall not be paid or otherwise distributed until such conditions have lapsed or have otherwise been satisfied. In addition, the Plan Administrator may provide that such amounts and Dividend Equivalents (if any) shall be deemed to have been reinvested in additional Shares or otherwise reinvested. In no event shall Dividend Equivalents be paid with respect to Options or SARs.

6.
Performance Criteria.

(a) The Plan Administrator may determine that, with respect to a Restricted Stock Award, a Restricted Stock Unit, a Performance Award or an Other Share-Based Award, the grant of such Award or the lapsing of restrictions thereon and the distribution of cash, Shares or other property pursuant thereto, as applicable, will be subject to the achievement of one or more objective performance goals established by the Plan Administrator. The Plan Administrator may use such business criteria and other measures of performance as it may deem appropriate in establishing any performance conditions. Subject to the terms of the Plan, the performance goals to be achieved during any Performance Period, the length of any Performance Period, the amount of any Performance Award granted and the amount of any payment or transfer to be made pursuant to any Performance Award shall be determined by the Plan Administrator. Such performance conditions may include (but are not limited to) the following:

(3)
operating income;
(4)
earnings per share;

(10)
earnings (including earnings before taxes, earnings before interest and taxes or earnings before interest, taxes, depreciation and amortization) margins, operating margins, gross margins or cash margin; and
(11)
debt reduction.

(b) Such performance goals may also be based solely by reference to the Company’s performance or the performance of a Company Affiliate, division, business segment or business unit of the Company, or based upon the relative performance of other companies or upon comparisons of any of the indicators of performance relative to other companies.

(c) For purposes of any performance goal established pursuant to this Section 6, the Plan Administrator may also exclude charges related to an event or occurrence which the Plan Administrator determines should appropriately be excluded, including (i) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges; (ii) an event either not directly related to the operations of the Company or not within the reasonable control of the Company’s management; or (iii) the cumulative effects of tax or accounting changes in accordance with U.S. generally accepted accounting principles.

(b) In the event of a Change in Control, the Plan Administrator may, in its sole discretion, and on such terms and conditions as it deems appropriate, take any one or more of the following actions with respect to any outstanding Award, which need not be uniform with respect to all Participants and/or Awards, unless otherwise specified in an Award Agreement:

(1) continuation or assumption of such Award by the Company (if it is the surviving corporation) or by the successor or surviving entity or its parent;

(2) substitution or replacement of such Award by the successor or surviving entity or its parent with cash, securities, rights or other property to be paid or issued, as the case may be, by the successor or surviving entity (or a parent or subsidiary thereof), with substantially the same terms and value as such Award (including any applicable performance targets or criteria with respect thereto);

(3) acceleration of the vesting of such Award and the lapse of any restrictions thereon and, in the case of an Option or SAR, acceleration of the right to exercise such Award during a specified period (and the termination of such Option or SAR without payment of any consideration therefor to the extent such Award is not timely exercised), in each case, either (A) in the case of an Award held by a non-employee director only, immediately prior to or as of the date of the Change in Control, (B) upon a Participant’s involuntary termination of employment or service (including upon a termination of employment or service by the Company (or a successor corporation or its parent) without “cause”, by a Participant for “good reason” and/or due to a Participant’s death or “disability”, as such terms may be defined in the applicable Award Agreement) on or within a specified period following the Change in Control or (C) upon the failure of the successor or surviving entity (or its parent) to continue or assume such Award;

(4) in the case of a Performance Award, determination of the level of attainment of the applicable performance condition(s); and

(5) cancellation of such Award in consideration of a payment, with the form, amount and timing of such payment determined by the Plan Administrator in its sole discretion, subject to the following: (A) such payment shall be made in cash, securities, rights and/or other property; (B) the amount of such payment shall equal the value of such Award, as determined by the Plan Administrator in its sole discretion; provided that, in the case of an Option or SAR, if such value equals the Intrinsic Value of such Award, such value shall be deemed to be valid; provided further that, if the Intrinsic Value of an Option or SAR is equal to or less than zero, the Plan Administrator may, in its sole discretion, provide for the cancellation of such Award without payment of any consideration therefor (for the avoidance of doubt, in the event of a Change in Control, the Plan Administrator may, in its sole discretion, terminate any Option or SAR for which the exercise or reference price is equal to or exceeds the per Share value of the consideration to be paid in the Change in Control transaction without payment of consideration therefor); and (C) such payment shall be made promptly following such Change in Control or on a specified date or dates following such Change in Control; provided that the timing of such payment shall comply with Section 409A of the Code.

9.
General Provisions Applicable to Awards.

(a) Transferability of Awards. Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution or, other than in the case of an Incentive Stock Option or an Award subject to Section 409A of the Code, pursuant to a qualified domestic relations order, and, during the life of the Participant, shall be exercisable (if applicable) only by the Participant; provided, however, that, except with respect to an Incentive Stock Option (unless such Incentive Stock Option is modified to become a Nonqualified Stock Option) or an Award subject to Section 409A of the Code, the Plan Administrator may permit or provide in the applicable Award Agreement for the gratuitous transfer of the Award by the Participant to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the Participant and/or an immediate family member thereof if the Company would be eligible to use Form S-8 under the Securities Act for the registration of the sale of the Shares subject to such Award to such proposed transferee; provided further, that neither the Company nor any Company Affiliate shall be required to recognize any such transfer until such time as such transferee shall, as a condition to such transfer, deliver a written instrument in form and substance satisfactory to the Company confirming that such transferee shall be bound by all of the terms and conditions of the applicable Award Agreement. References to a Participant, to the extent relevant in the context, shall include references to authorized transferees. For the avoidance of doubt, nothing contained in this Section 9(a) shall be deemed to restrict a transfer to the Company or a Company Affiliate.

(b) Documentation. Each Award Agreement may contain terms and conditions in addition to those specified in the Plan.

(c) Termination of Service.

(1) Except as may otherwise be provided in an Award Agreement or pursuant to Section 8(b)(3) or 9(c)(2), if a Participant’s employment or service with the Company or a Company Affiliate is terminated for any reason, any Award that is then (i) not vested shall terminate and be forfeited on the date of such employment or service termination, and (ii) vested shall, subject to Section 5(d), in the case of an Option or SAR, remain exercisable for 90 days after the termination date (or such other expiration date set forth in the Award Agreement).

(2) Notwithstanding the foregoing, in the event of a Participant’s termination of employment or service due to death or Disability:

(a) All Restricted Stock Awards, Restricted Stock Unit Awards, and Nonqualified Stock Option Awards that are (i) subject only to time-based vesting conditions and (ii) are outstanding and unvested as of the date of such termination of employment or service will become vested and, if applicable, fully exercisable, as of the date of such termination of employment or service, subject to the other terms and conditions of the applicable Award Agreements;

(b) A Pro-Rata Portion of Performance Awards (including Performance Stock Units and Performance Stock Options) that are outstanding and unvested as of the date of such termination of employment or service will become vested, and if applicable, exercisable, as of the date of such termination of employment or service, subject to the other terms and conditions of the applicable Award Agreements; provided that any applicable performance goals will be deemed achieved based on the actual level of performance of such performance goals as of the date of such termination of employment or service, as determined by the Committee, acting as Plan Administrator, in its sole discretion;

(c) The foregoing provisions of this Section 9(c)(2) shall apply to Awards or Prior Awards granted to Participants before and after the Restatement Effective Date; and

(d) Notwithstanding the foregoing, none of the actions set forth in this Section 9(c)(2) with respect to any applicable Award shall become effective if such actions would result in any additional tax, penalty or interest under Section 409A of the Internal Revenue Code of 1986, as amended, with respect to such Award.

(d) Withholding. The Participant must satisfy all income and employment tax withholding obligations before the Company or a Company Affiliate will deliver stock certificates (or the electronic equivalent thereof), cash or otherwise recognize ownership of the Shares upon the exercise or settlement of an Award. The Company or a Company Affiliate may elect to satisfy the withholding obligations through additional withholding on salary or wages. If the Company or a Company Affiliate elects not to or cannot withhold from other compensation, the Participant (either directly or through a broker) must pay to the Company or a Company Affiliate the full amount, if any, required for withholding. Except as otherwise may be provided for in an Award Agreement or approved by the Plan Administrator, a Participant may satisfy such tax obligations in whole or in part by delivery (either by actual physical delivery or by attestation) of Shares, including Shares retained from the Award creating the tax obligation, valued at their Fair Market Value (determined, for purposes of this Section (d), as of the date the tax obligation arises instead of the date of grant); provided, however, that the total tax withholding where stock is being used to satisfy such tax obligations cannot exceed the maximum statutory withholding obligations (based on maximum statutory withholding rates for federal and state tax purposes, including payroll taxes, that are applicable to such supplemental taxable income), to the extent such withholding would not result in liability classification of such Award (or any portion thereof) pursuant to FASB ASC Subtopic 718-10. Shares used to satisfy tax withholding requirements cannot be subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements.

(e) Amendment or Termination of Award. Except as otherwise provided in Section 5(i) with respect to repricings or Section 10(c) with respect to actions requiring stockholder approval, the Plan Administrator may amend, modify or terminate any outstanding Award. The Participant’s consent to such action shall be required (i) unless the Plan Administrator determines that the action, taking into account any

84 | SS&C 2025 PROXY STATEMENT

Appendix B: SS&C Technologies Holdings, Inc. AMENDED AND RESTATED 2023 Stock Incentive Plan

related action, does not materially and adversely affect the Participant’s rights under the Plan or (ii) the change is permitted under Section 8. Notwithstanding the foregoing or any other provision hereof, the Plan Administrator may, without the consent of the Participant, cancel and terminate any outstanding Award that has not been accepted by the Participant within 12 months after the grant date of such unaccepted Award.

(f) Conditions on Delivery of Stock. Neither the Company nor a Company Affiliate will be obligated to deliver any Shares pursuant to the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in connection with the issuance and delivery of such Shares have been satisfied, including any applicable securities laws and regulations and any applicable stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the requirements of any applicable laws, rules or regulations.

(g) Acceleration. The Plan Administrator may at any time provide that any Award shall become immediately vested and/or exercisable in whole or in part.

10.
Miscellaneous

(a) No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award by virtue of the adoption of the Plan, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company or any Company Affiliate. The Company and each Company Affiliate expressly reserve the right at any time to dismiss or otherwise terminate their relationship with a Participant free from any liability or claim under the Plan, except as expressly provided in the applicable Award Agreement.

(b) No Rights As Stockholder. Subject to the provisions of the applicable Award Agreement, no Participant, nor any legal representative of the Participant’s estate or legatee of the Participant under the Participant’s will, shall have any rights as a stockholder with respect to any Shares to be issued with respect to an Award until becoming the record holder of such Shares.

(c) Amendment of Plan. The Plan Administrator may amend, suspend or terminate the Plan or any portion thereof at any time provided that (i) no amendment that would require stockholder approval under the rules of NASDAQ may be made effective unless and until the Company’s stockholders approve such amendment; and (ii) if NASDAQ amends its corporate governance rules so that such rules no longer require stockholder approval of “material revisions” to equity compensation plans, then, from and after the effective date of such amendment to NASDAQ rules, no amendment to the Plan (A) increasing the number of Shares authorized under the Plan (other than pursuant to Section 8, (B) expanding the types of Awards that may be granted under the Plan, (C) materially expanding the class of participants eligible to participate in the Plan or (D) repealing the prohibition against repricing set forth in Section 5(i) shall be effective unless and until the Company’s stockholders approve such amendment. To the extent required for purposes of Section 422 of the Code, other amendments to the Plan shall be subject to approval by the Company’s stockholders. Unless otherwise specified in the applicable amendment, any amendment to the Plan adopted in accordance with this Section 10(c) shall apply to, and be binding on the holders of, all Awards outstanding under the Plan at the time the amendment is adopted, provided the Plan Administrator determines that such amendment, taking into account any related action, does not materially and adversely affect the rights of Participants under the Plan. No Award shall be made that is conditioned upon stockholder approval of any amendment to the Plan unless the Award provides that (i) it will terminate or be forfeited if stockholder approval of such amendment is not obtained within no more than 12 months from the date of grant and (2) it may not be exercised or settled (or otherwise result in the issuance of Shares) prior to such stockholder approval.

(d) Authorization of Sub-Plans (Including for Grants to Non-U.S. Employees). The Plan Administrator may from time to time establish one or more sub-plans under the Plan for purposes of satisfying applicable securities, tax or other laws of various jurisdictions. The Plan Administrator shall establish such sub-plans by adopting supplements to the Plan containing (i) such limitations on the Plan Administrator’s discretion under the Plan as the Plan Administrator deems necessary or desirable or (ii) such additional terms and conditions not otherwise inconsistent with the Plan as the Plan Administrator shall deem necessary or desirable. All supplements adopted by the Plan Administrator shall be deemed to be part of the Plan, but each supplement shall apply only to Participants within the affected jurisdiction.

(e) Compliance with Section 409A of the Code.

(1) Notwithstanding anything else herein, the Company makes no representation or warranty and shall have no liability to the Participant or any other person if any provisions of or payments, compensation or other benefits under the Plan are determined to constitute nonqualified deferred compensation subject to Section 409A of the Code but do not to satisfy the conditions thereof.

(2) Awards are intended to be exempt from Section 409A of the Code to the maximum extent possible. With respect to any Awards subject to Section 409A of the Code, the Plan is intended to comply with the requirements of Section 409A of the Code, and the provisions of the Plan and any applicable Award Agreement shall be interpreted in a manner that satisfies the requirements of Section 409A of the Code, and the Plan shall be operated accordingly. If any provision of the Plan or any term or condition of any Award would otherwise frustrate or conflict with this intent, the provision, term or condition will be interpreted and deemed amended so as to avoid this conflict.

(3) Except as provided in any individual Award Agreement initially or by amendment, if and to the extent (i) any portion of any payment, compensation or other benefit provided to a Participant pursuant to the Plan in connection with his or her termination of employment or service constitutes “nonqualified deferred compensation” within the meaning of Section 409A of the Code and (ii) the Participant is a “specified employee” as defined in Section 409A(a)(2)(B)(i) of the Code, in each case as determined by the Company in accordance with its procedures, such portion of the payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of “separation from service” (as determined under Section 409A of the Code) (the “New Payment Date”), except as Section 409A of the Code may then permit. The aggregate of any payments that otherwise would have been paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the Participant in a lump sum (without interest) on such New Payment Date, and any remaining payments will be paid on their original schedule. By accepting an Award, each Participant agrees that he or she is bound by the foregoing determinations and procedures.

(f) Limitations on Liability. Notwithstanding any other provisions of the Plan, no Plan Administrator nor any individual acting as a director, officer, or employee of the Company or a Company Affiliate will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan, nor will such individual be personally liable with respect to the Plan because of any contract or other instrument he or she executes in his or her capacity as Plan Administrator or as a director, officer, or employee of the Company or a Company Affiliate.

(g) Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the State of Delaware, excluding choice-of-law principles of the law of such state that would require the application of the laws of a jurisdiction other than the State of Delaware.

(h) Term Awards may be granted under the Plan at any time and from time to time on or prior to the tenth anniversary of the Restatement Effective Date, unless the Board adopts a resolution terminating the Plan or the maximum number of Shares available for issuance under the Plan has been issued prior to such tenth anniversary, on which date the Plan will expire except as to Awards then outstanding under the Plan. Such outstanding Awards shall remain in effect until they have been exercised or terminated, or have expired.

(i) Cancellation or “Clawback” of Awards. The Plan Administrator shall have full authority to implement any policies and procedures necessary to comply with Section 10D of the Exchange Act and any rules promulgated thereunder and any other regulatory regimes. Notwithstanding anything to the contrary contained herein, any Awards granted under the Plan (including any amounts or benefits arising from such Awards) shall be subject to any clawback or recoupment arrangements or policies the Company has in place from time to time, and the Committee may, to the extent permitted by applicable law and stock exchange rules or by any applicable Company policy or arrangement, and shall, to the extent required, cancel or require reimbursement of any Awards granted to the Participant or any Shares issued or cash received upon vesting, exercise or settlement of any such Awards or sale of Shares underlying such Awards.
