Letter from the CEO

|  |  |  | Dear Fellow Stockholders: On behalf of our Board of Directors and the entire Sallie Mae team, thank you for your continued support and investment in our company.

Our mission at Sallie Mae is grounded in an enduring belief in the power of higher education and its ability to unlock opportunities, strengthen communities, and help people build better futures. As the market leader for private student lending, we are proud to continue our steadfast support of students and their success as they navigate to, through, and immediately after higher education.

In many ways, 2025 was a watershed year for our industry. While there is still broad recognition of the value of higher education, important discussions about affordability, outcomes, and how students and families can maximize the value of their investment moved to the forefront. Significant reforms to the federal student loan program will change how students and families approach paying for college and should reduce the likelihood that they take on unsustainable levels of federal student debt. At the same time, schools accelerated innovation to develop programs better aligned with the needs of students and the future economy.

Our strategy positions us well for these changes. We continue to empower student success, and we have expanded our tools, resources, and insights to help families plan and pay for higher education. We are also leveraging our deep product and credit knowledge to enhance our core private student loan business through improvements in underwriting, credit administration, marketing, and other key functions. In addition,

we are introducing new offerings to better serve evolving student needs, including a far greater focus on graduate students, while maintaining a strong emphasis on responsible lending. Finally, our inaugural strategic partnership gives us the potential to serve a broader group of customers, improve capital efficiency, and support our disciplined growth strategy.

In this context, we are pleased to have delivered strong results for 2025. We expanded originations, maintained strong cosigner participation, improved our net charge-off rate, and returned capital to stockholders. These achievements generate real momentum for 2026 and beyond.

I look forward to our 2026 Annual Meeting of Stockholders on Tuesday, June 16, 2026, at 1 p.m. EDT, to be held virtually at www.virtualshareholdermeeting.com/SLM2026.

You can find details about the business to be conducted at the Annual Meeting and how to participate in the attached Notice of Annual Meeting and proxy statement. You are being asked to vote on several matters. Your vote is important, regardless of the number of shares you own, and all holders of our Common Stock are invited to attend the Annual Meeting. Please vote at your earliest convenience by following the instructions in the Notice of Availability of Proxy Materials or the proxy card you received in the mail.

We appreciate your continued confidence in Sallie Mae.

All best,

Jonathan W. Witter

SLM’s Strategy

To further focus our business and increase stockholder value, we continue to advance our strategic imperatives. Our primary focus is driving innovation to maximize the sustainable growth and profitability of our core private student loan business. Additionally, we aim to accelerate the growth of new lines of business to attract more customers requiring our products and services. We are also focused on building the data infrastructure, technology, and talent required to compete in a digital world. We seek to create a customer-centric brand as an education solutions company that supports students and families through their higher education journey. We are focused on driving greater internal commitment to our mission, brand, and strategy, while evolving our structure and risk capabilities to support our core private student loan business and emerging new businesses.

We strive to maximize the revenue of our core private student loan business by (i) driving penetration at all schools, (ii) increasing market share by bridging gaps in student funding needs, (iii) enhancing risk-adjusted pricing and underwriting, and (iv) improving marketing, digital, and data capabilities. In addition, we work to manage our unit costs by (a) maintaining a strong focus on fixed cost discipline, (b) driving towards reducing both the unit costs of servicing and the unit cost of acquisitions, (c) improving third-party vendor cost management, and (d) driving towards strong operating leverage.

In 2025, we announced our first strategic partnership. This new funding model allows us to establish a capital-light, fee-based revenue strategy that complements our core private student loan business. Under our strategic partnership (and any future partnerships that we may enter into), we intend to sell Private Education Loans while maintaining the relationships with customers, retaining servicing for the sold loans, and earning ongoing fees for providing servicing and program management, including industry expertise. We expect strategic partnerships to expand our access to scalable and capital efficient funding through innovative structures, while strengthening our loan originations capacity and ability to serve students families.

Additionally, we continued to optimize the value of our Sallie Mae brand and attractive client base by (i) building products and services that leverage our customer affiliation, (ii) ensuring alignment of our products and services with our core mission and driving customer value, (iii) prioritizing partnerships and other capital efficient avenues of growth, and (iv) seeking opportunities to optimize return on our investments.

2026 PROXY STATEMENT |  | 1

##### Table of Contents

PROXY STATEMENT SUMMARY

During 2025, we worked to maintain a rigorous capital allocation and return program by (i) paying quarterly Common Stock dividends to $0.13 per share, (ii) selling approximately $5.0 billion of Private Education Loans (as hereinafter defined), and (iii) repurchasing approximately 12.8 million shares of our Common Stock pursuant to Rule 10b5-1 trading plans authorized under our share repurchase programs.

Corporate Governance Highlights

We believe strong corporate governance is critical for our success. Integral to our governance structures are (i) director independence, as our Board of Directors as of December 31, 2025, was comprised of 92% independent directors, (ii) separate roles of Board Chair and Chief Executive Officer (“CEO”), (iii) active risk oversight by the Board of Directors and Board committees, (iv) a Code of Business Conduct for all directors, officers, and employees, (v) breadth of experience and perspective on our Board of Directors, and (vi) board refreshment evidenced by 46% of our Board of Directors having tenure of fewer than four years of service as of December 31, 2025.

Executive Compensation

Our executive compensation philosophy aligns the compensation received by our named executive officers with the Company’s performance. The Company’s performance-based compensation programs focus senior executives on goals that drive short- and long-term performance while balancing risk and reward. While the annual incentive plan came in slightly below target, the Company’s relative total shareholder return performance under our Long-Term Incentive Plan 2023 performance stock units was strong, and we believe executive compensation is aligned with Company performance. For more information on executive compensation, including our practices and philosophy, please see the “Compensation Discussion & Analysis” on page 29.

Highlights of 2025 Company Performance

• |  | 2025 Net Income Attributable to Common Stock (calculated in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”)) of $729 million, as compared to $590 million in the prior year.

• |  | $3.46 GAAP Diluted Earnings Per Common Share for 2025, as compared to $2.68 for the prior year.

• |  | Private Education Loan Originations of $7.4 billion in 2025, as compared to $7.0 billion in 2024, an approximate 6 percent increase year-over-year.

• |  | Private Education Loan held for investment portfolio, net, totaled $20.3 billion as of December 31, 2025, as compared to $20.9 billion as of December 31, 2024, an approximate 3 percent decrease year-over-year.*

• |  | Efficiency Ratio of 33.2% for 2025, a decrease from 34.7% for 2024.**

• |  | 2.15% Total Net Charge-Offs as a Percentage of Average Loans in Repayment in 2025, a decrease from 2.19% in 2024.

##### Table of Contents

Proposal 1

Election of Directors

SLM Corporation’s Board of Directors has nominated and recommends 13 individuals for election to the Board of Directors at the Annual Meeting. These individuals are as follows:

Under our Certificate of Incorporation, the size of our Board of Directors may not be fewer than 11 nor more than 16 members. Under the Bylaws, the Board of Directors has the authority to determine the size of the Board of Directors within that range and to fill any vacancies that may arise prior to the next annual meeting of stockholders. The Board of Directors has set the number of members at 13.

Biographical information, qualifications, and experience with respect to each director nominee appear below. In addition to fulfilling the general criteria for director nominees described in the section titled “Nominations Process,” each nominee possesses experience, skills, attributes, and other qualifications the Board of Directors has determined support its oversight and management of Sallie Mae’s business, operations, and structure.

Each nominee is a current director who was elected by stockholders at the 2025 annual meeting of stockholders. All nominees appearing below consented to being named in this proxy statement and to serve if elected. Should any nominee subsequently decline or be unable to accept such nomination to serve as a director, the Board of Directors may reduce its size, designate a substitute nominee or the persons voting the shares represented by proxies solicited hereby may vote such shares for a reduced number of nominees. If the Board of Directors designates a substitute nominee, persons named as proxies will vote “FOR” that substitute nominee.

2026 PROXY STATEMENT |  | 5

##### Table of Contents

PROPOSAL 1| ELECTION OF DIRECTORS

The Company’s Bylaws provide the election of a director in an uncontested election will be by a majority of the votes cast with respect to a nominee at a meeting for the election of directors at which a quorum is present. Each share of Common Stock is entitled to one vote for each nominee. A director nominee will be elected to the Board of Directors if the number of shares voted “FOR” the nominee exceeds the number of votes cast “AGAINST” the nominee’s election. Abstentions and shares not voted on the proposal, including broker non-votes, are of no effect for the outcome of the election.

If any director nominee fails to receive a majority of the votes cast “FOR” their election, such nominee will automatically tender their resignation upon certification of the election results. The Nominations and Governance Committee of the Board of Directors will make a recommendation to the Board of Directors on whether to accept or reject such nominee’s resignation. The Board of Directors will act on the Nominations and Governance Committee’s recommendation and publicly disclose its decision and the rationale behind it within 90 days from the date of certification of the election results.

2026 PROXY STATEMENT |  | 13

##### Table of Contents

Proposal 2

Advisory Vote on Executive Compensation

Pursuant to Schedule 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and related SEC rules, Sallie Mae is asking stockholders to approve an advisory resolution (commonly referred to as a “say-on-pay” resolution) on its executive compensation as reported in this proxy statement. Sallie Mae urges stockholders to read the “Compensation Discussion and Analysis” section (“CD&A”) of this proxy statement, which describes how our executive compensation policies and procedures operate and are designed to achieve the Company’s compensation objectives, as well as the Summary Compensation Table and other related compensation tables and narrative, which provide detailed information on the compensation of the Company’s named executive officers (“NEOs”).

At our annual meeting of stockholders held in June 2025, we submitted a non-binding vote to our stockholders to approve our executive compensation. Approximately 99.1 percent of the stockholders present or represented, and entitled to vote thereon, voted in favor of the say-on-pay proposal. We attribute that broad support in part to our continued efforts to understand and address the feedback we received from our stockholders. Specifically, in 2025 we continued to focus on performance-based compensation for our NEOs as we (i) tied a significant portion of total NEO compensation to the achievement of performance goals we believe drive the fundamentals of our business and (ii) awarded a significant percentage, 60 percent for the CEO and 50 percent for all other NEOs, of the NEO’s long-term incentive plan (“LTIP”) equity awards in the form of performance-based awards consisting of performance stock units (“PSUs”). As summarized above, there were no structural changes to the NEOs’ components of compensation in 2025 compared to the prior year.

The 2025 compensation awarded to our CEO, Jonathan W. Witter, and other NEOs reflects the execution on our strategic priorities and related performance period results. Those strategic priorities were in line with management’s expectations and a continued commitment to shareholder return. The Compensation Committee is mindful of its responsibility to align executive compensation with the overall performance of the Company, while taking into consideration the need to provide market competitive compensation in order to recruit and retain highly skilled and experienced executives. The CD&A provides a comprehensive discussion and rationale for the 2025 pay decisions made by the Compensation Committee and the correlation to Company performance.

The Board of Directors believes the Company’s compensation design demonstrates the Company’s responsiveness to its stockholders, its commitment to its pay-for-performance philosophy, and its goal of aligning management’s interests with those of its stockholders to support the creation of long-term value.

The Board of Directors has adopted a policy providing for annual “say-on-pay” advisory votes. In accordance with this policy and Section 14A of the Exchange Act, and as a matter of good corporate governance, Sallie Mae is asking stockholders to approve the following advisory resolution at the Annual Meeting:

“Resolved, that Sallie Mae’s stockholders approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis and the related compensation tables and narrative disclosure in this proxy statement.”

This proposal to approve the resolution regarding the compensation of Sallie Mae’s NEOs requires the affirmative vote of the holders of a majority in voting power of the Common Stock present or represented, and entitled to vote thereon. Abstentions have the same effect as votes “AGAINST” the matter. As this is a “routine” matter, we do not expect any broker non-votes on this matter. This proposal is advisory in nature and, therefore, is not binding upon the Compensation Committee or the Board of Directors. However, the Compensation Committee will carefully evaluate the outcome of the vote when considering future executive compensation decisions. Following our Annual Meeting, we expect to hold the next advisory say-on-pay vote at our 2027 annual meeting of our stockholders.

Board of Directors Recommendation

|  |  |  |  |  |  |  |  |  | The Board of Directors recommends a vote “FOR” the Approval, on an Advisory Basis, of the Compensation of our Named Executive Officers, as Disclosed in the Compensation Discussion and Analysis and the Related Compensation Tables and Narrative Disclosure in this Proxy Statement. |  |  |  |  |  |

Proposal 3

Ratification of the Appointment of the Independent Registered Public Accounting Firm

Sallie Mae’s independent registered public accounting firm, KPMG, is selected by the Audit Committee of Sallie Mae’s Board of Directors (the “Audit Committee”). KPMG served as Sallie Mae’s independent registered public accounting firm for the fiscal year ended December 31, 2025, and the Audit Committee has engaged KPMG as Sallie Mae’s independent registered public accounting firm for the fiscal year ending December 31, 2026. Representatives of KPMG are expected to be present at the Annual Meeting, and they will have the opportunity to respond to appropriate questions from stockholders and to make a statement if they desire to do so.

This proposal is put before the stockholders because the Board of Directors believes it is a good corporate governance practice to provide stockholders a vote on ratification of the selection of the independent registered public accounting firm.

For ratification, this proposal will require the affirmative vote of the holders of a majority in voting power of the Common Stock present or represented, and entitled to vote thereon. Abstentions have the same effect as votes “AGAINST” the matter. Shares not voted on the matter have no direct effect on the outcome of this matter. If the appointment of KPMG is not ratified, the Audit Committee will evaluate the basis for the stockholders’ vote when determining whether to continue the firm’s engagement. Even if the selection of Sallie Mae’s independent registered public accounting firm is ratified, the Audit Committee may direct the appointment of a different independent registered public accounting firm at any time during 2026 if, in its discretion, it determines such a change would be in the Company’s best interests.

Board of Directors Recommendation

|  |  |  |  |  |  |  |  |  | The Board of Directors recommends a vote “FOR” Ratification of the Appointment of KPMG as Sallie Mae’s Independent Registered Public Accounting Firm for 2026. |  |  |  |  |  |

Corporate Governance

Roles and Responsibilities of the Board of Directors

The Board of Directors believes strong corporate governance is critical to achieving Sallie Mae’s performance goals and to maintaining the trust and confidence of investors, employees, regulatory agencies, and other stakeholders.

The primary responsibilities of the Board of Directors are to:

• |  | review and approve Sallie Mae’s key strategic imperatives and business plan;

• |  | advise and provide oversight of management regarding, and monitor performance against, the Company’s strategic imperatives and business objectives;

• |  | monitor the Company’s financial performance and condition, and through its Audit Committee review and oversee the auditing and integrity of Sallie Mae’s financial statements and periodic public reports, its internal audit function, and select and oversee Sallie Mae’s independent registered public accounting firm;

• |  | select the CEO, and through the independent directors, evaluate the performance of, approve the compensation of, and engage in succession planning for the CEO;

• |  | evaluate the performance of, engage in succession planning for, and compensate members of the executive management team through the Compensation Committee;

• |  | review risks affecting Sallie Mae and its processes for managing those risks, and oversee the risk management and internal control frameworks, compliance, and governance, including through annually approving Sallie Mae’s Risk Management Policy, and Board-level risk appetite metrics, and monitoring Sallie Mae’s risk profile through a quarterly review of performance against Board-approved risk metrics;

• |  | oversee and advise on Sallie Mae’s capital allocation, including capital and liquidity levels, and review and approve Sallie Mae’s capital return initiatives, including dividends and share repurchase programs; and

• |  | recruit and recommend appropriate director candidates for election by stockholders, and engage in an annual self-assessment process to evaluate the effectiveness of the Board of Directors and its committees.

Board Governance Guidelines

The Board of Directors’ Governance Guidelines (the “Guidelines”) are reviewed each year by the Nominations and Governance Committee, which from time to time will recommend changes to the Board of Directors. The Guidelines are published at www.salliemae.com/investors/corporate-governance/ and a written copy may be obtained by contacting the Corporate Secretary at corporatesecretary@salliemae.com or SLM Corporation, 300 Continental Drive, Newark, DE 19713. The Guidelines, along with Sallie Mae’s Bylaws and committee charters, have informed our governance practices, providing that including, among others:

• |  | A majority of the members of the Board of Directors must be independent directors, and all members of the (i) Audit, (ii) Nominations and Governance, (iii) Compensation, and (iv) Financial Risk Committees must be independent.

• |  | All directors stand for re-election each year. Directors are elected under a majority vote standard in uncontested elections.

• |  | We have separated the role of Board Chair from CEO and have an independent Board Chair.

• |  | Each regularly scheduled Board of Directors meeting generally concludes with an executive session in which only independent members of the Board of Directors participate. Each regularly scheduled committee meeting also generally concludes with an executive session presided over by the committee Chair.

• |  | We seek representation on the Board of Directors that will contribute breadth of experience and knowledge in areas important to the operations of Sallie Mae, including, but not limited to, accounting, finance, business strategy and operations, banking, higher education, information technology, risk management, marketing, corporate governance, and legal, regulatory, political, or governmental affairs, and that reflects a variety of attributes and qualities.

• |  | We maintain stock ownership and retention guidelines for directors.

• |  | The Board of Directors and its committees undertake an annual review to evaluate their effectiveness.

• |  | Directors should not serve on more than three other public company boards in addition to the Company’s Board of Directors. In addition, directors who are executive officers of public companies should not serve on any other public company board beyond their employer’s board and the Company’s Board of Directors.

• |  | Non-employee directors should retire from the Board of Directors no later than at the annual meeting of stockholders following such director’s 75th birthday.

CORPORATE GOVERNANCE

Board Leadership Structure

Ms. Franke, an independent director of the Company and Sallie Mae Bank, our wholly-owned subsidiary (the “Bank”), serves as the chair of the Board of Directors of the Company as well as the Board of Directors of the Bank. Our independent Board Chair serves as the principal representative of the Board of Directors, presiding over meetings of the Board of Directors. Mr. Witter, our CEO, serves as a member of the Board of Directors. The Board of Directors believes, at this time, an independent director is best situated to serve as Board Chair as an effective counterbalance to management and our CEO. By separating the CEO role from the Board Chair role, the Company is put in the best position to oversee all executives of the Company, monitor and respond to key risks and strategic initiatives at the Company, and act in the best interest of stockholders. The Board of Directors believes the Company is currently best served by separating the roles of Board Chair and CEO, while, subject to Sallie Mae’s Bylaws, the Board of Directors reserves the right to revisit this structure and combine the two roles, depending on the future needs and strategy of the Company at any given point in time.

Director Independence

For a director to be considered independent, the Board of Directors must determine the director does not have any direct or indirect material relationship with Sallie Mae. The Board of Directors has adopted the Guidelines, which embody the corporate governance principles and practices of the Company. The Guidelines include the standards for determining director independence, which are more stringent than the independence standards of the NASDAQ Global Select Market (“NASDAQ”) listing standards.

The Board of Directors has determined that each of the individuals who served as a director during 2025 and all nominees standing for election at the Annual Meeting, other than Mr. Witter, our CEO, are independent of Sallie Mae under the NASDAQ listing standards and Sallie Mae’s own director independence standards set forth in the Guidelines.

Each member of the Board of Directors’ Audit, Nominations and Governance, and Compensation Committees is independent within the meaning of the NASDAQ listing standards for each such committee, Exchange Act Rule 10A-3, and Sallie Mae’s own director independence standards set forth in the Guidelines. The Guidelines are published at www.salliemae.com/investors/corporate-governance/.

|  | Board Composition Our Board of Directors believes breadth of experience and perspective is important and seeks representation across a range of professional experience and regularly assesses a variety of attributes and qualities when identifying and evaluating director candidates. As of December 31, 2025, the tenure of our Board of Directors consisted of the following: |  |
|  | *  As of December 31, 2025, 46% of our Board of Directors has a tenure of fewer than four years of service |  |

CORPORATE GOVERNANCE

Risk Oversight

The Board of Directors and its committees oversee Sallie Mae’s overall strategic direction, including setting risk management philosophy and tolerances and parameters. The Board of Directors and its committees provide effective challenge to the risk management processes, practices, and reporting that the management team develops and implements. Management escalates to the Board of Directors and/or its committees significant departures from established risk tolerances and parameters and newly identified or emerging risks. Throughout the year, the Board of Directors and/or its committees dedicate a portion of their meetings to reviewing and discussing specific risk topics in greater detail with senior management, including risks related to cybersecurity. We believe this risk oversight structure complements our current Board leadership structure of separate Chair and CEO roles and each of the committees of the Board of Directors being comprised solely of independent directors. The primary risk oversight responsibilities of each of the standing committees of the Board of Directors are as follows:

|  | Audit Committee • reviews financial statements and periodic public reports; • reviews reports prepared by management and/or external auditor setting forth significant financial reporting issues; • reviews sufficiency of internal controls over financial reporting and disclosure controls; • engages and communicates with our independent registered public accounting firm; and • oversees operation of the internal audit function, its staffing, and its audit plan. |  |
|  | Nominations and Governance • implements good governance policies and measures for Sallie Mae and our Board of Directors; • recommends nominees for election to the Board of Directors; • facilitates self-assessments of the performance of the Board of Directors and its committees; and • provides oversight of proposed related party transactions and, when necessary and appropriate, makes recommendations to the Board of Directors regarding approval of related party transactions. |  |
|  | Compensation Committee • oversees all compensation and benefits for the CEO, executive officers, and independent directors; • oversees equity-based compensation plans and the annual incentive plan; • reviews management’s administration of employee benefit plans; • reviews management succession planning; • oversees human capital management; and • reviews and confirms our incentive compensation practices properly balance risk and reward and do not encourage excessive risk-taking. |  |
|  | Financial Risk Committee • monitors and provides oversight of our major financial risks, including credit, market, and liquidity risks; • reviews our risk management framework as it pertains to financial risks and supporting governance structure, roles, and responsibilities established by management; • reviews our risk management framework and conducts regular reviews of key risk measures with respect to financial risks; • reviews and, when necessary and appropriate, approves loan securitization transactions and other significant transactions by the Company or its affiliates; and • oversees frameworks and strategies pertaining to market, liquidity, and capital risk management and reviews capital and liquidity stress testing scenarios and key assumptions. |  |
|  | Operational and Compliance Risk Committee • monitors and provides oversight of our major non-financial risks, including operational and compliance risks; • reviews our risk management framework as it pertains to non-financial risks and supporting governance structure, roles, and responsibilities established by management; • reviews our risk management framework and conducts regular reviews of key risk measures with respect to non-financial risks; • oversees and monitors information security and cyber-related risks; • monitors risk management capabilities related to third-party service providers, information and data security, privacy, crisis preparedness, and operational resilience; • provides oversight of material pending or potential legal and regulatory matters impacting the Company; • oversees and monitors the Company’s compliance management system; • oversees the Bank’s implementation of relevant operational and compliance programs in alignment with regulatory obligations; and • oversees model risk management framework. |  |
|  | Preferred Stock Committee • monitors and evaluates our business activities in light of the rights of holders of the Company’s preferred stock. |  |

All members of the Board of Directors also serve as members of the board of directors of the Bank and its committees. Our Audit, Compensation, Nominations and Governance, Financial Risk, and Operational and Compliance Risk committees perform similar oversight roles for the Bank.

CORPORATE GOVERNANCE

Nominations Process

The Nominations and Governance Committee considers for nomination to the Board of Directors candidates recommended by stockholders and members of the Board of Directors. Candidates are evaluated based on the needs of the Board of Directors and Sallie Mae at that time. The Board of Directors seeks representation across a range of professional experiences and backgrounds and regularly assesses a variety of attributes and qualities when identifying and evaluating director candidates. The minimum qualifications and attributes the Nominations and Governance Committee believes a director nominee must possess include:

• |  | knowledge of Sallie Mae’s business;

• |  | a proven record of accomplishment;

• |  | willingness to commit the time necessary for Board of Directors service;

• |  | integrity and sound judgment in areas relevant to the business;

• |  | impartiality to stockholders;

• |  | the ability to challenge and stimulate management; and

• |  | independence.

To recommend a candidate, stockholders should send, in writing, the candidate’s name, credentials, contact information, and their consent to be considered as a candidate to the Chair of the Nominations and Governance Committee at corporatesecretary@salliemae.com or c/o Corporate Secretary, SLM Corporation, 300 Continental Drive, Newark, Delaware 19713. The stockholder should also include their contact information and a statement of their share ownership. The nomination deadline for the 2026 Annual Meeting has closed. A stockholder wishing to nominate a candidate for the 2027 Annual Meeting must comply with the notice and other requirements in the Bylaws as described under “Stockholder Proposals for the 2027 Annual Meeting” in this proxy statement.

Related Party Transactions

Sallie Mae has a written policy regarding review and approval of related party transactions. Transactions covered by the policy are transactions in excess of $120,000 in any year involving Sallie Mae in which any director, nominee, executive officer, or greater-than-five percent beneficial owner of the Company, or any of their respective immediate family members, has or had a direct or indirect material interest, other than solely as a director and/or less-than-ten percent owner of an entity involved in the transaction (“Related Party Transactions”). Loans made in the ordinary course of Sallie Mae’s business to executive officers, directors, and their family members are considered Related Party Transactions and are pre-approved. The Bank has also adopted written policies to implement the requirements of Regulation O of the Board of Governors of the Federal Reserve System, which restricts the extension of credit to directors and executive officers and their family members and other related interests. Under these policies, extensions of credit that exceed regulatory thresholds must be, and are, approved by the board of directors of the Bank.

Under the Related Party Transactions policy, the Chief Legal, Government Affairs, and Communications Officer will notify the Chair of the Nominations and Governance Committee of any proposed Related Party Transaction, and the Chair of the Nominations and Governance Committee will determine if approval under the policy is required. If required, the Nominations and Governance Committee will review the proposed Related Party Transaction and make a recommendation to the Board of Directors regarding whether to approve the transaction. In considering a transaction, the Nominations and Governance Committee and the Board of Directors consider whether a transaction would be on terms no less favorable than to an unaffiliated third party under the same or similar circumstances, among other factors.

Political Expenditures

Our current policy on political activities is publicly available on our website at www.salliemae.com/investors/corporate-governance/ and sets forth the principles regarding our stance on political activities. The Company complies with federal, state, and local lobbying registration and disclosure requirements. The Company works closely with the Nominations and Governance Committee to review and assess our existing policies, procedures, and decision-making approaches to government relations and political activities.

At this time, the Company has one long-term, experienced employee engaged in lobbying activities exclusively related to matters that directly or indirectly affect the Private Education Loan (as hereinafter defined) industry and our mission. The compensation of the employee, and other executives, for time attributed to lobbying activity is reported as lobbying expenditure. That employee manages

external, bipartisan lobbying/consulting firms that assist with the same objectives, and we report the lobbying-related expenditures made to external firms in our lobbying disclosures. The Company’s involvement with industry associations is limited to those associations comprised of financial institutions with similar interests.

Quarterly disclosures detailing our lobbying activities and expenditures, as required by the Lobbying Disclosure Act of 1995, are posted online by the Clerk of the U.S. House of Representatives and the Secretary of the U.S. Senate. Disclosures relating to contributions by our Political Action Committee are posted online by the Federal Election Commission (“FEC”). We will continue to comply with all applicable laws and regulations on disclosure of those activities.

The Sallie Mae Political Action Committee (“PAC”)

In June 2015, the Company formed the Sallie Mae PAC. Our PAC is governed by an Advisory Board comprised of six employees, who represent different divisions within the Sallie Mae organization. The PAC’s Advisory Board reviews and approves all PAC contributions. The PAC’s Advisory Board evaluates candidates, of any party, on factors that include the candidate’s views on policy matters impacting Sallie Mae and our employees, the candidate’s committee or leadership role, and representation of Sallie Mae facilities and employees.

Our PAC contributions are published on the FEC website.

Stockholder Communications with the Board

Stockholders and other interested parties may submit communications to the Board of Directors, the non-management directors as a group, the Board Chair, or any other individual member of the Board of Directors by contacting the Corporate Secretary in writing at corporatesecretary@salliemae.com or c/o Corporate Secretary, SLM Corporation, 300 Continental Drive, Newark, Delaware 19713. Each communication will be reviewed by the Corporate Secretary to determine whether it is appropriate for presentation to the Board of Directors or applicable director(s). The purpose of this screening is to allow our directors to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations, and product inquiries).

Code of Business Conduct

We have a Code of Business Conduct that applies to the Board of Directors and all employees. The Code of Business Conduct is available on our website (www.salliemae.com/investors/corporate-governance/) and a written copy is available from the Corporate Secretary. We intend to post amendments to, or waivers of, the Code of Business Conduct, if any (to the extent applicable to the Company’s principal executive officer, principal financial officer, principal accounting officer, or any director), at this location on our website.

At the beginning of each year, the Audit Committee approves the proposed services, including the nature, type, and scope of service contemplated and the related fees, to be rendered by the firm during the year.

Reporting is provided to the Audit Committee regarding services the Chair of the Audit Committee pre-approved between committee meetings.

COMPENSATION DISCUSSION AND ANALYSIS

Executive Summary

The Compensation Discussion and Analysis (“CD&A”), describes our compensation practices and programs in the context of our NEOs. The components of our compensation program are in place to promote prudent management decision-making and profitably drive the evolution of our business, all while ensuring we motivate, reward, and retain highly qualified talent. In many cases, our compensation practices and programs applicable to our NEOs also apply to senior executive employees other than our NEOs.

Our primary business is to originate and service high-quality Private Education Loans. “Private Education Loans” are education loans for students or their families that are not made, insured, or guaranteed by any state or federal government. We also offer a range of deposit products insured by the Federal Deposit Insurance Corporation (“FDIC”). We serve more families than any other private student loan lender. Our Private Education Loans serve primarily to bridge the gap between the cost of higher education and the amount funded through family income and savings, scholarships and grants, and federal financial aid. We also extend Private Education Loans as an alternative to similar federal education loan products where we believe our rates are competitive. We originated approximately $7.4 billion of Private Education Loans in 2025, an increase of 6 percent from the year ended December 31, 2024. As of December 31, 2025, we had $20.3 billion of Private Education Loans held for investment, net, outstanding.

Our compensation programs include (i) a short-term annual cash bonus (the “AIP Award”) under our annual incentive plan (the “Annual Incentive Plan” or “AIP”), and (ii) time and performance-based awards under the LTIP, consisting of (x) a grant of time-based restricted stock units (“RSUs”) that vests in one-third increments over a three-year period, and (y) a grant of performance stock units (“PSUs”) that vests based on a relative total shareholder return (“TSR”) measure following a three-year performance period, focusing our senior executives on goals that drive our financial performance while balancing risk and reward and aligning compensation with the interests of our stockholders.

As discussed in more detail herein, our 2025 AIP Awards are determined by corporate and individual performance, encouraging executives to focus on the Company’s overall performance by aligning to the following four metrics:

• |  | Pre-Tax, Pre-Provision, Pre-Non-interest Expense Income Per Share (“Adjusted Income Per Share”)

• |  | Private Education Loan Originations (“Loan Originations”)

• |  | Non-interest Expenses Excluding FDIC and AIP Expense (“Adjusted Non-interest Expenses”)

• |  | Total Loan Portfolio Net Charge-Offs as a percentage of average loans in repayment (“Net Charge-Offs”)

Payouts and performance under the 2025 AIP were lower than that of the 2024 performance year. The change in the AIP performance from the prior year is attributable to rigorous year over year goal setting and close to target performance for 2025 (compared to above target performance in 2024). For a detailed summary of the 2025 AIP performance, please see page 38.

We believe continued emphasis on performance-based compensation in the short-term, coupled with continued focus on TSR as a key metric for performance-based equity compensation in the long-term, align our executives’ compensation with the interests of our stockholders.

Compensation Philosophy

The pay-for-performance philosophy underlying our executive compensation program provides our executives a competitive total compensation package tied to both Company and individual performance, designed to align with the interests of our stockholders and to attract and retain highly qualified executives. We adhere to the following principles aligned with our compensation philosophy to achieve our executive compensation program objectives:

• |  | Tie a significant portion of the total compensation of our executives to the achievement of enterprise-wide goals that drive stockholder value;

• |  | Ensure executive compensation rewards both short-term and long-term performance; and

• |  | Promote the alignment of sustained Company performance and stockholder value without encouraging excessive risk taking.

Stockholder Engagement, Compensation Governance, and Say-on-Pay Results

Stockholder Engagement and Compensation Governance

We engage with our stockholders and proxy advisory firms throughout the year, as appropriate, and provide stockholders with an annual opportunity to cast an advisory say-on-pay vote. At our 2025 annual meeting of stockholders, approximately 99.1 percent of the votes present or represented, and entitled to vote thereon, voted in favor of our say-on-pay proposal. Through stockholder engagement, we can consider important information on compensation policies and practices, as applicable. In addition, the outcome of the say-on-pay vote results will continue to inform future compensation decisions. Over the last five years, stockholders have strongly supported our executive compensation program, with 89 percent or more of the votes cast in support of the program each year.

COMPENSATION DISCUSSION AND ANALYSIS

Elements of Compensation

The compensation program in 2025 for the NEOs consisted of seven elements. These elements, as well as the reasons why each was chosen and the ways in which each achieves the Company’s compensation objectives, are described below:

Compensation Element |  | Description |  | Objective
Base Salary |  | Fixed cash compensation. Reviewed annually and adjusted as appropriate. |  | To provide a base level of cash compensation for senior executives based on level and responsibility.
AIP Awards |  | Variable compensation. 2025 AIP Awards have been determined based on corporate and individual performance. Corporate funding metrics were derived from management’s 2025 objectives identified in our annual business plan. AIP Awards are payable in cash from the AIP funding pool upon consideration of each NEO’s individual performance against their respective goals. |  | To encourage alignment and reward senior executives for achieving annual corporate performance and individual goals.
Long-Term Equity-Based Incentives |  | RSUs and PSUs (2025 Design) |  | Multi-year equity compensation generally granted annually. In 2025, the long-term equity-based incentive plan for the NEOs, excluding the CEO, consisted of 50 percent RSUs that vest in one-third increments over a three-year period and 50 percent PSUs that cliff vest in three years based on relative TSR with a one-year holding period after vesting. In 2025, the long-term equity-based incentive plan for the CEO consisted of 40 percent RSUs that vest in one-third increments over a three-year period and 60 percent PSUs that cliff vest in three years based on relative TSR with a one-year holding period after vesting. |  | To motivate and retain senior executives by aligning their interests with that of stockholders through sustained performance and growth.
Other |  | Health, welfare, and retirement benefits |  | Benefits programs are provided to executives in the same manner as all benefits-eligible employees. |  | To promote employee health and provide retirement planning opportunities.
| Deferred Compensation Plan and Supplemental 401(k) Savings Plan |  | Retirement benefit. The Sallie Mae Deferred Compensation Plan and the Supplemental 401(k) Savings Plan provide a vehicle into which certain employees can opt to defer a portion of their compensation for retirement. These opportunities are provided in lieu of any pension benefit plans. |  | To provide retirement planning opportunities.
| Severance benefits |  | Under the Amended and Restated Executive Severance Plan for Senior Officers, the Company provides compensation and benefits upon qualifying employment termination events, including fixed cash compensation-based severance payments. Equity awards generally continue to vest on the respective awards’ terms after changes of control, involuntary terminations other than for cause, or if the grantee voluntarily ceases employment and meets our retirement eligibility requirements. For more information, see “Arrangements with Named Executive Officers” below on page 57. |  | To maintain continuity of management in the event of major restructurings or after a change of control and provide temporary income following involuntary terminations of employment other than for cause.
| Limited Perquisites |  | Fixed compensation. Consists primarily of executive physical examinations and, in limited instances, housing relocation expenses. |  | To provide business-related benefits to assist in attracting and retaining key executives.

COMPENSATION DISCUSSION AND ANALYSIS

In establishing compensation levels and structures, policies, and performance for 2025, the Compensation Committee also considered the results of the 2025 annual meeting of stockholders “say-on-pay” advisory vote of stockholders, which received the approval of approximately 99.1 percent of the holders of the Common Stock present or represented, and entitled to vote thereon. Given the positive results of the stockholder advisory vote and the Compensation Committee’s ongoing review of our compensation programs, the Compensation Committee believes the Company’s existing executive compensation programs effectively align the interests of the NEOs with the Company’s short-term and long-term goals.

Base Salary Determinations

The Compensation Committee considers whether to make base salary adjustments annually. The following factors are considered in determining base salary adjustments, if any, for the NEOs:

• |  | Scope and responsibility of the NEO’s position;

• |  | Overall compensation paid by the compensation peer group for comparable positions;

• |  | Recruitment, retention, and development of leadership talent; and

• |  | Appropriate balancing of each NEO’s base salary against their incentive compensation.

Based on these factors, after diligent review and discussion, and in consultation with its compensation consultant, the Compensation Committee determined that NEO base salary compensation was appropriately positioned compared to the market and paid in accordance with scope and responsibility. As a result, the NEOs’ base salaries did not increase in 2025 as compared to the prior year as provided in the table below.

Named Executive Officer |  | 2024 Base Salary ($) |  | 2025 Base Salary ($) |  | % Increase

2025 Annual Incentive Plan for Named Executive Officers

|  | The following are highlights of the 2025 AIP: • The following four funding metrics were utilized to determine the AIP funding pool under the 2025 AIP at the following weightings: • Adjusted Income Per Share* (40 percent); • Loan Originations (25 percent); • Adjusted Non-interest Expenses** (20 percent); and • Net Charge-Offs (15 percent). • Each NEO in the 2025 AIP had an established target AIP Award opportunity as set by the Compensation Committee, with no guaranteed minimum (i.e., the actual AIP Award payout could be 0 percent of target). • Included a clawback and risk adjustment provision. • The CRO completed a risk assessment and program review of the 2025 AIP, as well as quarterly qualitative risk reviews of the performance against the 2025 AIP funding metrics. • Under the 2025 AIP, the NEOs’ annual AIP Awards were paid in cash from the AIP funding pool upon consideration of each NEO’s individual performance against their respective goals. *   See Appendix A (A-1) – Reconciliation of Non-GAAP Financial Measures for a more detailed explanation of Non-GAAP Adjusted Income Per Share and a reconciliation to GAAP diluted earnings per common share. **  See Appendix A (A-2) – Reconciliation of Non-GAAP Financial Measures for a more detailed explanation of Non-GAAP Adjusted Non-interest Expenses and a reconciliation to GAAP total non-interest expenses. |  |

Annual Incentive Plan Goal Setting

Each year, management develops a rigorous business plan that reflects the Company’s strategy for achieving operating and financial results to enhance franchise value while prudently growing our business. The Company’s business plan was the foundation used to derive the performance goals approved by the Compensation Committee for purposes of establishing the 2025 AIP targets and funding metrics. In consultation with its independent compensation consultant, the Compensation Committee carefully analyzed, reviewed, and finalized these performance goals.

As a financial institution, our funding metrics for the 2025 AIP were designed to balance asset growth, credit quality, operating expenses, and risk management by utilizing a mix of financial metrics (Adjusted Income Per Share and Adjusted Non-interest Expenses), a customer growth metric (Loan Originations), and a credit quality metric (Net Charge-Offs). In selecting objective performance metrics and establishing challenging target, threshold, and maximum levels, the Compensation Committee considered the upcoming year’s business objectives and outlook. Rather than only examining and relying upon the prior year’s targets and actual results, which may not reflect the current year’s expectations, challenges, and opportunities affecting our industry, the Compensation Committee’s goal setting process considers particular and timely market trends that are likely to impact our business based on current activity, as well as the Company’s goals and other industry specific factors.

Pursuant to the AIP, the Compensation Committee may exercise discretion to adjust the performance goals established at the beginning of the year, including the ability to consider corporate performance metrics either on a GAAP or non-GAAP adjusted basis and other qualitative factors, as appropriate. This combination of fixed formulas, along with the latitude in assessing performance based on the Compensation Committee’s informed judgment, allows for consideration of unanticipated market conditions and other events that may impact operating performance. The Company believes this latitude is important in mitigating risk as it reduces the potential that the NEOs may be encouraged to take actions with respect to unanticipated items based on the impact the actions may have on their incentive compensation, rather than based on the merits and impact the actions may have on achieving our long-term goals and objectives.

COMPENSATION DISCUSSION AND ANALYSIS

Four corporate metrics were established by the Compensation Committee to determine the funding of the 2025 AIP.

As discussed above, these four metrics were derived from management’s 2025 objectives identified in our annual business plan. These metrics, their rationale, and the weightings at which they were set are discussed in the table below.

Metric |  | Weighting |  | Rationale for Using Each Metric
Adjusted Income Per Share |  | 40% |  | This is a key metric used by management to measure internally the Company’s performance for the year. This measure allows management to evaluate the Company’s performance and ability to generate earnings from its primary business. Adjusted Income Per Share is a non-GAAP measure that is derived from GAAP diluted earnings per common share for 2025 and increases that amount by (i) the impact of the GAAP provision for credit losses per common share for 2025, (ii) the impact of the GAAP total non-interest expense per common share for 2025, (iii) the impact of the GAAP income tax expense per common share for 2025, and (iv) the impact of GAAP preferred stock dividends per common share for 2025. For 2025, the Compensation Committee approved a target of $9.20 for Adjusted Income Per Share. The 2025 target was set taking into consideration, among other items, the gain expected to be recognized by the Company from the potential sale of certain Private Education Loans in 2025 and the expected impact of potential share repurchases in 2025. A calculation and GAAP to Non-GAAP reconciliation of Adjusted Income Per Share, as well as certain calculation modifications to this metric the Compensation Committee approved in connection with the funding of the 2025 AIP, can be found at Appendix A (A-1).
Loan Originations |  | 25% |  | This measurement serves as a key indicator of the trajectory of our business, including our future earnings and asset growth. For 2025, the Compensation Committee approved a target of $7.504 billion for Loan Originations, a 9.4 percent increase from the $6.86 billion target in 2024, due to expected market growth and market share improvements.
Adjusted Non-interest Expenses |  | 20% |  | This is a key measurement used to evaluate the expense discipline of the Company regarding costs attributable to running our business. FDIC expense and AIP expense are excluded from the calculation of this metric as those expenses are outside the control of management. Adjusted Non-interest Expenses is a non-GAAP measure. The determination of Adjusted Non-interest Expenses starts with GAAP total non-interest expenses and decreases that amount by FDIC assessment fees and AIP expense. For 2025, the Compensation Committee approved a target of $565 million for Adjusted Non-interest Expenses. The 2024 Operating Expenses Excluding FDIC Assessment Fees and AIP Expense target was $551.5 million. The 2025 Adjusted Non-interest Expenses target was based on anticipated increase in spending to drive loan origination growth and other strategic initiatives. A calculation and GAAP to Non-GAAP reconciliation of Adjusted Non-interest Expenses, as well as a certain calculation modification to this metric the Compensation Committee approved in connection with the funding of the 2025 AIP, can be found at Appendix A (A-2).
Net Charge-Offs |  | 15% |  | This metric is used to measure the credit performance of our loan portfolio, a significant indicator of the health of our business. In order to align with our 2025 net charge-offs guidance metric, the Net Charge-Offs AIP metric was calculated as net charge-offs as a percentage of average loans in repayment. For 2025, the Compensation Committee approved a target of 2.1 percent for Net Charge-Offs. For 2024, the Compensation Committee approved a target of $355 million for total loan portfolio net charge-offs measured in dollars as opposed to percentages for 2025. The Net Charge-Offs performance target considered the application of historical roll rate performance to expected Private Education Loan repayment balances. The Compensation Committee set this challenging Net Charge-Offs goal to focus management on credit performance, one of the Company’s key priorities for the 2025 fiscal year.

COMPENSATION DISCUSSION AND ANALYSIS

Minimum, target, and maximum achievement levels were set for each performance metric and a weighting assigned to each performance metric based on its relative importance to our overall operating plan. The NEOs each have a target opportunity for their AIP awards that cannot exceed two times their target. Additionally, no individual AIP Award can exceed $5 million.

2025 AIP Funding and Payout Computation

In February 2025, the Compensation Committee established the AIP pool funding metrics. In February 2026, the Compensation Committee, including the independent Board Chair, reviewed our relative achievement of the previously established AIP pool funding metrics and, after discussions with our CEO, determined that for the year ended December 31, 2025 the AIP pool should be funded at 96.2 percent based on the achievement of the four funding metrics, taking into account certain calculation modifications approved by the Compensation Committee, as summarized in the table below.

Application of the 2025 AIP funding score, based on the four funding metrics approved in February 2025, resulted in the following:

(Dollars in Millions, except per share amounts and percentages)

Funding Metric |  | Min |  | Target |  | Max |  | Actual Performance |  | Award Factor |  | Weighting |  | Funding Metric Score
Adjusted Income Per Share(1) |  |  |  | $8.50 |  |  |  |  | $9.20 |  |  |  |  | $9.90 |  |  |  |  | $9.24(3) |  |  |  |  | 101 | % |  |  |  | 40 | % |  |  |  | 40.4 | %

Adjusted Non-interest Expenses(2) |  |  |  | $595.6 |  |  |  |  | $565.0 |  |  |  |  | $534.3 |  |  |  |  | $566(4) |  |  |  |  | 99 | %(6) |  |  |  | 20 | % |  |  |  | 19.9 | %
Net Charge-Offs |  |  |  | 2.38% |  |  |  |  | 2.10% |  |  |  |  | 1.82% |  |  |  |  | 2.15% |  |  |  |  | 97 | %(6) |  |  |  | 15 | % |  |  |  | 14.6 | %
Total |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  | 96.2 | %

(1) | Adjusted Income Per Share is a Non-GAAP metric under the 2025 AIP that is derived from GAAP net income. See Appendix A (A-1) for a GAAP to Non-GAAP reconciliation.

(2) | Adjusted Non-interest Expenses is a Non-GAAP metric under the 2025 AIP that is derived from GAAP total non-interest expenses. See Appendix A (A-2) for a GAAP to Non-GAAP reconciliation.

(3) | In determining the performance of this Non-GAAP metric under the 2025 AIP, the Compensation Committee, when reviewing the funding of the 2025 AIP, approved certain calculation modifications to omit the impact of the following events: (i) the negative impact of the impairment of certain non-marketable securities owned by the Company and (ii) the positive impact of the gain associated with the sale of certain loans outside of the Company’s business plan. Those calculation modifications had an overall negative impact to the performance of this metric and resulted in the actual performance used for purposes of the funding of the 2025 AIP changing from $9.41 per share to $9.24 per share. See Appendix A (A-1) for a GAAP to Non-GAAP reconciliation.

(4) | In determining the performance of this Non-GAAP metric under the 2025 AIP, the Compensation Committee, when reviewing the funding of the 2025 AIP, approved a calculation modification to omit the negative impact of certain expenses incurred pertaining to the Company’s strategic initiatives that were offset by reduced FDIC assessment fees not reflected in the calculation of this metric. This calculation modification resulted in the actual performance of the metric used for purposes of the funding of the 2025 AIP changing from $584 million to $566 million. See Appendix A (A-2) for a GAAP to Non-GAAP reconciliation.

(5) | The Company did not achieve the Loan Originations target; below-target performance reflected increased competitive intensity and more selective underwriting, including credit tightening, consistent with management’s focus on disciplined, high quality growth.

(6) | The Net Charge-Offs and Adjusted Non-interest Expenses metrics performed slightly below AIP targets. However, both metrics performed within the guidance range communicated to external investors.

With a 2025 AIP funding score of 96.2 percent, the Compensation Committee assessed each NEO’s individual performance against outcome-based goals as further detailed in the section titled “NEO Achievements” below. Each NEO’s respective individual performance was assessed during the annual performance review and covered employees risk review, in the following four areas: (i) driving performance against investor expectations; (ii) delivering on strategic imperatives; (iii) supporting and continuing to develop risk management capabilities; and (iv) evolving leadership and culture to support our strategy. With respect to the 2025 AIP, as in prior years, the Compensation Committee had discretion to increase or reduce any AIP Award amount, including down to

zero, that would otherwise be earned or payable to any participant and to consider assessment of any other additional factors. The AIP Award payment to each NEO under the 2025 AIP is set forth below.

Named Executive Officer |  | Target AIP Award as a % of Base Salary |  | 2025 Target AIP Award $ Amount |  | 2025 AIP Payout
Jonathan W. Witter |  |  |  | 160 | %(1) |  |  | $ | 1,760,000 |  |  |  | $ | 1,672,000 |

Nicolas Jafarieh |  |  |  | 125 | % |  |  | $ | 630,000 |  |  |  | $ | 976,500 |

(1) | In February 2025, the Compensation Committee approved an increase of 10 percentage points to Mr. Witter’s target AIP Award under the 2025 AIP, raising his target AIP Award opportunity from 150% of his annual base salary to 160% of his annual base salary, to ensure his compensation as the CEO remains competitive with the market and to further tie his compensation to the Company’s performance.

(2) | In February 2025, the Compensation Committee approved an increase of 25 percentage points to Ms. Vieira’s target AIP Award under the 2025 AIP, raising her target AIP Award opportunity from 125% of her annual base salary to 150% of her annual base salary, to ensure her compensation as the Executive Vice President and Chief Commercial Officer remains competitive with the market and to further tie her compensation to the Company’s performance.

2025 NEO Long-Term Incentive Program

In connection with our 2025 NEO LTIP awards, the Compensation Committee utilized a combination of RSUs and PSUs. The combination of RSUs and PSUs was different for the CEO as compared to the other NEOs. Accordingly, the CEO received 40 percent RSUs and 60 percent PSUs, and all other NEOs received 50 percent RSUs and 50 percent PSUs. RSUs vest in one-third increments over each anniversary of the grant date, and PSUs cliff-vest in 2028 upon certification by the Compensation Committee as to the achievement of the relative TSR performance metric with a one-year required holding period after vesting. Our 2025 LTIP grants serve as a retentive tool intended to provide long-term incentive and performance-based compensation that aligns NEO compensation to our TSR compared to that of our peers, thus aligning the NEO’s interests with the interests of our stockholders.

|  | 2025 PSUs for NEO Long-Term Incentive Awards |  |  |  | • For the NEOs, including Mr. Witter, the PSUs granted in 2025: • vest between 0 percent and 200 percent in 2028 based on the Company’s relative TSR from January 1, 2025 to December 31, 2027; • vest upon the Compensation Committee’s certification of the Company’s actual performance relative to the pre-established PSU peer group; and • require a one-year holding period immediately following the vesting date of the PSUs. |  |

Relative TSR

We believe relative TSR, the sole PSU performance metric, aligns the interests of management with those of our stockholders. The Company’s relative TSR is evaluated by comparing the Company’s stock price performance to a defined set of comparable companies based on size, volatility, stock price correlation, and industry. The relative TSR is based on the Company’s TSR as compared to the peer group composed of companies belonging to the following sub-industries in the following published indices as of January 1, 2025: (i) The S&P Supercomposite Consumer Finance Sub-Industry Index; and (ii) The S&P 400 Regional Bank Sub-Industry Index.

We annually review the Company’s LTIP design to ensure alignment with the strategic plan and the interests of our stockholders. The PSU design is derived from a rigorous process that involved input and discussions among the Compensation Committee, the CEO, human resources, finance, risk management, legal, and guidance from the Compensation Committee’s independent compensation consultant.

Vesting of the 2023 PSU Grants

In February 2023, 50 percent of the 2023 LTIP award granted to Mr. Witter, Ms. Palmer, Ms. Vieira, and Mr. Jafarieh consisted of PSUs that vested in February 2026 at 176 percent of target based on relative TSR in the 88th percentile as detailed in the table below. The table below shows the threshold, target, and maximum payout percentages associated with the relative TSR PSU performance metric for the 2023 PSU grants.

Relative TSR based on the performance period from February 17, 2023 through February 17, 2026

The earnout ranges from 0% to 200% depending on TSR Performance Against Peer Group.*

TSR of the Company relative to TSR of the Peer Group |  | Payout Percentage of PSUs
100th Percentile |  |  |  | 200 | %
75th Percentile |  |  |  | 150 | %
50th Percentile |  |  |  | 100 | %
25th Percentile |  |  |  | 50 | %
< 25th Percentile |  |  |  | 0 | %

* | The Peer Group is composed of companies belonging to the following sub-industries in the following published indices as of February 17, 2023: (i) The S&P Supercomposite Consumer Finance Sub-Industry Index; and (ii) The S&P 400 Regional Bank Sub-Industry Index.

Pursuant to the terms of the 2023 PSU awards, in February 2026 the Compensation Committee approved and certified the actual performance of the relative TSR PSU performance metric based on the performance period from February 17, 2023 through February 17, 2026.

Accordingly, because the 2023 PSUs vested at 176 percent of target, in February 2026, Mr. Witter, Ms. Palmer, Ms. Vieira, and Mr. Jafarieh received the following number of shares of Common Stock pursuant to the vesting of their 2023 PSU grants:

Name |  | Target Number of Shares of Common Stock Pursuant to the 2023 PSU Award |  | Actual Number of Shares of Common Stock Pursuant to the 2023 PSU Award(1)
Jonathan W. Witter |  |  |  | 192,152 |  |  |  |  | 338,188 |
Kerri A. Palmer |  |  |  | 28,203 |  |  |  |  | 49,637 |
Donna F. Vieira |  |  |  | 33,170 |  |  |  |  | 58,379 |
Nicolas Jafarieh |  |  |  | 33,455 |  |  |  |  | 58,880 |

(1) | Includes Dividend Equivalent Units. In addition, such shares require a one-year holding period until February 24, 2027.

Mr. Graham did not receive PSUs in 2023, and thus did not have any PSU grants that vested in February 2026.

Risk Assessments and Reviews of Compensation Plans

The CRO coordinates forward-looking risk assessments, backward-looking program reviews, quarterly risk reviews of performance against incentive compensation plans, and ongoing oversight of Sallie Mae’s incentive compensation plans with a cross-functional team of Sallie Mae’s senior officers from the risk management and human resources departments. The CRO’s responsibilities include oversight of the annual forward-looking risk assessments and backward-looking program reviews of our incentive compensation plans to help ensure our employees are not incentivized to take inappropriate risks that could impact our financial position and controls, reputation, and operations, and developing policies and procedures to help ensure our incentive compensation plans are designed to achieve their business goals within acceptable risk parameters. In coordination with the Chief People Officer, the CRO periodically reports to the Compensation Committee on the results of the independent quarterly risk reviews of performance against our incentive compensation plans.

As part of the annual forward-looking risk assessment in 2025, the CRO determined and presented to the Compensation Committee that the risks embedded in the AIP and LTIP were within the Company’s ability to effectively monitor and manage, properly balance risk and reward, and were not likely to promote excessive risk-taking. In addition, as part of the annual backward-looking program review of incentive compensation plans, the CRO confirmed the Company’s incentive compensation plans are sufficiently risk sensitive, do not encourage excessive risk-taking, are consistent with the safety and soundness of Sallie Mae, and are otherwise consistent with applicable law and the applicable regulatory rules and guidance.

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Consultant

The Compensation Committee retains an independent compensation consultant to advise on relevant market practices and specific compensation programs. A representative of the compensation consultant attended meetings of the Compensation Committee, as requested, and communicated with the Chair of the Compensation Committee. Aon’s Human Capital Solutions practice, a division of Aon PLC (otherwise known as McLagan), serves as the Compensation Committee’s compensation consultant. The compensation consultant has provided the following services, among other things:

• |  | assisting in developing a peer group of companies for benchmarking director and executive compensation;

• |  | providing market-relevant information as to the composition of director and executive compensation;

• |  | providing views on the reasonableness of amounts and forms of director and executive compensation;

• |  | assisting the Compensation Committee with incentive plan design decisions;

• |  | providing guidance on regulatory changes; and

• |  | reviewing drafts and commenting on the Compensation Discussion and Analysis and related compensation tables for the proxy statement.

From time to time, but no less than annually, the Compensation Committee considers the independence of the compensation consultant in light of SEC rules and NASDAQ listing standards. At this time, the Compensation Committee has concluded there is no conflict of interest with regard to the compensation consultant.

Compensation Committee Interlocks and Insider Participation

All members of the Compensation Committee are independent directors, and no current member is or has been an employee of Sallie Mae. During 2025, none of our executive officers served on a compensation committee (or its equivalent) or board of directors of another entity whose executive officer served on the Board of Directors or the Compensation Committee.

Peer Group Analysis

In determining the compensation of the CEO and other NEOs, the Compensation Committee utilizes a peer group for purposes of benchmarking compensation against market practices. Recognizing that the Company has a limited number of direct peer companies and in consultation with its compensation consultant, the peer group (i) is periodically reviewed and updated by the Compensation Committee, (ii) consists of companies that are similar in size (revenue and market capitalization), and (iii) consists of organizations that are generally in similar industries as the Company and with whom the Company may compete for executive talent. No changes were made to the peer group in 2025.

The peer group utilized for purposes of benchmarking NEO compensation is as follows:

Peer Group (Ticker)
Ally Financial Inc. (ALLY) |  | LendingClub Corporation (LC)
Axos Financial, Inc. (AX) |  | LendingTree, Inc. (TREE)
BankUnited, Inc. (BKU) |  | OneMain Holdings, Inc. (OMF)
Commerce Bancshares, Inc. (CBSH) |  | Prosperity Bancshares, Inc. (PB)
Credit Acceptance Corporation (CACC) |  | SoFi Technologies, Inc. (SOFI)
Enova International, Inc. (ENVA) |  | Synovus Financial Corp. (SNV)
F.N.B. Corporation (FNB) |  | Upstart Holdings, Inc. (UPST)

The Compensation Committee believes it is appropriate to continuously monitor relative compensation amounts with respect to the same peer group used by management and the Board of Directors for financial performance comparisons.

Other Arrangements, Policies, and Practices Related to Executive Compensation Programs
Share Ownership Guidelines
As of December 31, 2025, the guidelines for beneficial ownership of our Common Stock were as follows:

• |  | CEO (Mr. Witter)—six times the CEO’s annual base salary; and

• |  | Executive Vice President (including Mr. Graham, Ms. Palmer, Ms. Vieira, and Mr. Jafarieh)—three times the Executive Vice President’s annual base salary.

The guidelines encourage continued beneficial ownership of a significant amount of our Common Stock and help align the interests of the Company’s executives with the interests of our stockholders. No executive, including the CEO, may engage in any sale, distribution, or other transfer of Common Stock prior to the achievement of the requirements set forth above. Additionally, no executive, including the CEO, may engage in any sale, distribution, or other transfer of Common Stock if such transaction would result in the failure to meet the minimum ownership requirements as set forth above.
All current NEOs were in compliance with the share ownership guidelines as of December 31, 2025.
Equity Grant Policies and Practices
We generally grant equity compensation to eligible employees on an annual basis during the first quarter of the fiscal year. Our Human Resources team reviews the annual LTIP program provisions and grant levels in the beginning of the first quarter of the year to coincide with the annual performance management compensation review process established by the Company for all employees. As a part of that process each year, the Human Resources team
pre-establishes
a grant date at the end of the performance year for grants during an expected open trading window to eligible employees, subject to the business considerations of the Company, as approved by the Compensation Committee. Consistent with our current practice, in 2025 the annual equity grants to all eligible employees were awarded on March 3, 2025, during an open trading window and following the Compensation Committee meeting approving such annual equity grants, which such meeting was scheduled over one year in advance of the grant date. The Company historically does not strategically time long-term incentive awards in coordination with the release of material
non-public
information (“MNPI”) and has never had a practice of doing so. In addition, the Company has never timed, and does not plan to time, the release of MNPI for the purpose of affecting the value of executive compensation.
The Company does not currently grant stock options, stock appreciation rights (SARs), or similar awards with “option-like” features, and thus the Company has not adopted a policy regarding the timing of any such awards in connection with the disclosure of MNPI.
The Compensation Committee approves all grants of equity compensation to be awarded to executive officers (other than the CEO). In addition, the Compensation Committee recommends to the Board of Directors for approval all proposed grants of equity compensation to be awarded to the CEO and directors.
From time to time, the Company may find it necessary to issue equity awards to
non-executive
employees outside of the normal annual grant process. Accordingly, pursuant to the Compensation Committee Charter and the SLM Corporation 2021 Omnibus Incentive Plan (the “2021 Plan”), the Compensation Committee has delegated limited authority to the CEO (who is a director) to make grants to new hires as well as promotional, retention, and/or special
one-time
grants to employees who are not subject to Section 16(b) of the Exchange Act. Such authority is limited to an aggregate dollar amount per eligible employee as determined by the Compensation Committee at the beginning of each year. For these grants, our procedures provide that such grants be made on the first business day of each quarter, as applicable. Any grants made by the CEO pursuant to this delegation of authority are reported to the Compensation Committee on a quarterly basis. Based on this information, the Compensation Committee determines whether the grant of such delegation of authority was appropriate and whether additional authority should be granted to the CEO. Pursuant to this delegated limited authority, the CEO is not permitted to make grants to our NEOs or persons subject to Section 16(b) of the Exchange Act.
Our equity award accounting policy complies with GAAP in the United States and is disclosed in our SEC filings.

COMPENSATION DISCUSSION AND ANALYSIS
Insider Trading Policy
The Company has a Securities Trading Policy in place as adopted by the Nominations and Governance Committee of the Board, which governs the purchase, sale, and other dispositions of our securities by our directors, officers, and employees, or the Company itself. The Securities Trading Policy is designed to promote compliance with insider trading laws, rules and regulations, and applicable listing standards. The Securities Trading Policy is filed as Exhibit 19.1 to the Company’s Annual Report on
Form 10-K
for the year ended December 31, 2025.
Hedging and Pledging Prohibition
Pursuant to the Company’s Securities Trading Policy, the Company prohibits directors, executive officers, and senior management from selling Common Stock short, buying or selling call or put options or other derivatives, and/or entering into other transactions that have the effect of hedging the economic value of any of their beneficial ownership of our shares.
Pursuant to the Company’s Securities Trading Policy, the Company also prohibits directors, executive officers, and senior management from purchasing Common Stock on margin or otherwise pledging Common Stock as collateral for a loan.
The Company prohibits hedging and pledging by our directors, executive officers, and senior management because they have the greatest ability to influence the direction of the Company and have a proportionally higher equity ownership than other employees generally. Accordingly, the Company expects its directors, executive officers, and senior management to bear the risks and rewards of stock ownership. The Company believes prohibiting hedging and pledging of Company securities by its directors, executive officers, and senior management is an important governance matter because it promotes alignment with our stockholders.
Clawback
Equity awards made under the 2021 Plan as well as the SLM Corporation 2012 Omnibus Incentive Plan (the “Predecessor Plan”) and AIP awards made to executives, including the NEOs, contain clawback provisions in the event of a material misstatement of the Company’s financial results and certain other events. In addition, the Company maintains an Incentive Compensation Adjustment Standard (the “Adjustment Standard”) and a Financial Restatement Compensation Recovery Policy (the “Clawback Policy”), which provide for the Compensation Committee’s authority and responsibilities to review and adjust, as applicable, employee cash- and/or equity-based incentive compensation and severance payments or benefits paid under Company severance plans (as described below), including reducing, eliminating, and/or clawing back cash- and/or equity-based incentive compensation or severance.
Under the Adjustment Standard, in the event (i) any employee engages in any act or omission that constitutes Misconduct and/or Excessive Risk-based Performance (as such terms are defined in the Adjustment Standard) or (ii) the Company is required to restate its financial statements due to the employee’s gross negligence, intentional misconduct, or fraud, the Compensation Committee (or, with respect to the CEO, the Board of Directors) has the discretion to require a reduction, forfeiture, recoupment, or clawback of any cash- and/or equity-based incentive compensation or severance payments or benefits.
Under the Clawback Policy, in the event of a financial restatement, the Compensation Committee (or, with respect to the CEO, the Board of Directors), will recover the amount of incentive-based compensation received by our executive officers that exceeds the amount that would have been received if the error had not been made within the three years preceding the date on which the Board of Directors determines the financial measure contains a material error (regardless of any fault of the executive officer for the accounting errors or other actions leading to a financial restatement). The Clawback Policy is filed as Exhibit 97.1 to the Company’s Annual Report on Form
10-K
for the year ended December 31, 2025.
Tax Information: Section 162(m) of the Internal Revenue Code
Section 162(m) of the Internal Revenue Code limits the tax deductibility of compensation for certain executive officers exceeding $1 million. The Compensation Committee continues to have the flexibility to pay
non-deductible
compensation if it believes it is in the best interests of the Company.

(1) | RSU and PSU awards are eligible to accrue dividends as DEUs, which vest on the same schedule as the underlying grant.

(2) | The grant date fair value of the RSU awards ($29.26) is determined by multiplying the original number of RSUs granted by the closing price of the Company’s Common Stock on the grant date. The Company did not issue fractional RSUs to account for the number between the grant date fair value and the amount approved by the Compensation Committee. No discounts have been applied to reflect the delayed vesting of these awards. The fair value of the PSU award is determined by using the 20 day trading average ($30.14) leading up to the grant date to determine the number of PSUs granted multiplied by the fair value ($33.47) as determined under ASC Topic 718.

(3) | For each NEO, the “Target” and “Maximum” amounts set forth in this row in the “Estimated Future Payouts under Non-Equity Incentive Plan Awards” column constitute each NEO’s respective target AIP Award and maximum AIP Award, potentially payable in cash under the 2025 AIP. 2025 AIP amounts were awarded in cash on February 27, 2026, and the actual amounts awarded are reported in the “Non-Equity Incentive Plan Compensation” column of the 2025 Summary Compensation Table.

Nonqualified Deferred Compensation for

Fiscal Year 2025

Deferred Compensation Plan for Key Employees

Under the Sallie Mae Deferred Compensation Plan for Key Employees (“DC Plan”), eligible employees may elect to defer up to 100 percent of their AIP Award and up to 85 percent of their base salary. Amounts deferred by plan participants are credited to record-keeping accounts, and participants are general creditors of the Company with regard to their accounts.

The Company makes contributions to the DC Plan only if, and to the extent that, a participant’s deferral under this plan reduces the contribution that would have been made under our tax-qualified defined contribution plan. Participants’ accounts are credited with earnings based on the investment performance of underlying investment funds, as selected by participants. Earnings credited do not constitute “above-market” earnings as defined by the SEC. Earnings are credited daily.

Participants elect the time and form of payment of their accounts. Accounts may be distributed either in a lump sum or annual installments. Accounts may also be paid while a participant is “in service” on a pre-specified date, provided the distribution date is at least two years after the date of the last deferral.

No contributions under the DC Plan were made for any NEO for 2025. The table below under “Supplemental 401(k) Savings Plan” provides information about the nonqualified deferred compensation of the NEOs in 2025.

Supplemental 401(k) Savings Plan

Under the Sallie Mae Supplemental 401(k) Savings Plan (“Supplemental 401(k)”), eligible employees may elect to defer five percent of their base salary and AIP Award or up to $500,000 of total eligible pay (or a combined deferral of $845,000 in both the 401(k) and Supplemental 401(k)).

We may also make matching contributions to a participant’s account. We will match a participant’s contribution after the participant completes 12 months of service. Participants are fully vested in our matching contributions at all times. Participants may elect to have their plan accounts deemed invested in the core investment funds offered under our tax-qualified 401(k) plan, and earnings are credited to participants’ Supplemental 401(k) accounts when such amounts would have been credited under our tax-qualified 401(k) plan. Earnings credited to the participants’ accounts do not constitute “above-market” earnings as defined by the SEC.

Participants elect the time and form of payment from their accounts. Accounts are paid in cash in a lump sum or by annual installments spread out over a maximum of 10 years. A participant may request an early distribution if the participant experiences a substantial, unforeseen financial hardship (as defined in the plan).

Arrangements with Named Executive Officers

Amended and Restated Executive Severance Plan

Under the Amended and Restated Executive Severance Plan for Senior Officers, effective as of June 18, 2024 (the “Amended and Restated Severance Plan”), any employee of the Company and/or the Bank with a position at the level of Vice President or higher (including NEOs) (each, an “Eligible Officer”) is eligible to receive severance payments and benefits in connection with the occurrence of the following events (in each case as defined in the Amended and Restated Severance Plan) (each, a “Qualifying Termination”): (i) a Termination of Employment Without Cause; (ii) a Termination of Employment For Good Reason; and (iii) a Termination of Employment By Job Abolishment. Subject to an Eligible Officer’s execution and nonrevocation of a customary release of claims and agreeing to certain restrictive covenants, an Eligible Officer who experiences a Qualifying Termination will receive the following severance payments and benefits: (a) an amount, in a lump sum payment, equal to (i) the applicable Multiplier (as described below), multiplied by (ii) the sum of (x) the Eligible Officer’s annual base salary and (y) the Eligible Officer’s target AIP Award opportunity for the year of termination (the “Severance Payment”); (b) outplacement services; and (c) COBRA continuation coverage subsidized by the Company for a specified period. For purposes of the Amended and Restated Severance Plan, the “Multiplier” is determined based on the Eligible Officer’s level as follows: (i) for the CEO, two (2); (ii) for an Eligible Officer with a title higher than Executive Vice President (such as Senior Executive Vice President or Vice Chairman) but not including the CEO, one and one half (1.5); (iii) for Executive Vice Presidents and Senior Vice Presidents, one (1); and (iv) for Vice Presidents, zero and three quarters (0.75). The Severance Payment will be subject to reduction in the event there is a risk element by which the Company determines the Severance Payment must be reduced, regardless of whether the Eligible Officer was involved in the risk element. Subject to an Eligible Officer’s estate’s execution and nonrevocation of a customary release of claims, an Eligible Officer who experiences a termination of employment on account of death will receive an amount equal to the applicable Multiplier multiplied by the Eligible Officer’s annual base salary.

Effective as of December 31, 2025, each NEO is eligible to receive severance under the Amended and Restated Severance Plan upon a Qualifying Termination.

Amended and Restated Change in Control Severance Plan

On June 18, 2024, the Board of Directors approved and adopted the Amended and Restated Change in Control Severance Plan for Senior Officers (the “Amended and Restated Change in Control Severance Plan”), effective as of June 18, 2024.

Under the Amended and Restated Change in Control Severance Plan, any employee of the Company and its subsidiaries with a position at the level of Senior Vice President or above (including NEOs) (each, a “CIC Plan Eligible Officer”) is eligible to receive severance payments and benefits in connection with the following termination events occurring within the six months preceding or the 24 months following a Change in Control of the Company (as defined in the Amended and Restated Change in Control Severance Plan): (i) a Termination of Employment Without Cause; and (ii) a Termination of Employment For Good Reason. Subject to a CIC Plan Eligible Officer’s execution and nonrevocation of a customary release of claims and agreeing to certain restrictive covenants, a CIC Plan Eligible Officer who experiences such termination will receive the following severance payments and benefits:

• |  | an amount, in a lump sum payment, equal to (i) the applicable multiplier set forth in the Amended and Restated Change in Control Severance Plan, which is determined based on the CIC Plan Eligible Officer’s level (2.5 for CEO, 2.0 for any CIC Plan Eligible Officer with a title higher than Senior Vice President (other than the CEO), and 1.5 for Senior Vice President), multiplied by (ii) the sum of (x) the “CIC Plan Eligible Officer’s Base Salary” and (y) the “CIC Plan Eligible Officer’s Target Bonus Opportunity” (in each case as defined in the Amended and Restated Change in Control Severance Plan). For purposes of the Company’s current NEOs, the multiplier is 2.5 for Mr. Witter, and 2.0 for each of Mr. Graham, Ms. Palmer, Ms. Vieira, and Mr. Jafarieh;

• |  | outplacement services; and

• |  | if the CIC Plan Eligible Officer properly elects COBRA, the Company will subsidize a portion of the total cost of the CIC Plan Eligible Officer’s health insurance premiums for a specified period as provided in the Amended and Restated Change in Control Severance Plan.

Any outstanding and unvested equity awards held by a CIC Plan Eligible Officer upon a Change in Control will generally continue under the terms and conditions applicable to such grants; provided, however, in certain circumstances, if the “Surviving Corporation” (as defined in the Amended and Restated Change in Control Severance Plan) does not adopt and assume a CIC Plan Eligible Officer’s equity awards, all equity awards held by such CIC Plan Eligible Officer will vest and (if applicable) become exercisable,

with any performance conditions measured at the greater of (1) 100% target level set forth in the vesting schedule therein, or (2) the actual level of performance as set forth in the applicable award agreement, as determined by the Compensation Committee as of the most recent practicable date prior to such Change in Control.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL TABLE

(1) | For equity vesting—Assumes all equity awards are assumed by the surviving/acquiring company in a change in control.

(2) | For equity vesting pertaining to a change in control with termination without cause or for good reason—Amounts shown are the value of RSU awards (including all DEUs) that would vest for each individual on December 31, 2025, based on the closing market price of the Company’s Common Stock on that date of $27.06. Assumes such RSUs are not assumed by the acquiring or surviving entity in a change of control. For equity vesting pertaining to a termination by the Company without cause or by the executive for good reason—Upon termination, these awards generally continue to vest based on their original vesting terms. For equity vesting pertaining to termination by death or disability, see footnote 9 below for additional information.

(3) | For PSUs, Company performance is calculated at target for the purposes of this calculation. Upon a change in control with termination without cause or for good reason, such PSUs not previously vested shall vest immediately. Upon a termination by the Company without cause or by the executive for good reason, such PSUs generally continue to vest based on their original vesting terms. For equity vesting pertaining to termination by death or disability, see footnote 9 below for additional information.

(4) | In the instance of a change in control with termination without cause or for good reason, medical insurance consists of the Company’s estimated portion of the cost of health care benefits for 24 months for Mr. Graham, Ms. Palmer, Ms. Vieira, and Mr. Jafarieh. In the case of Mr. Witter, benefits will be provided for 30 months.

(5) | In the instance of a termination by the Company without cause or by the executive for good reason, medical insurance consists of the Company’s estimated portion of the cost of health care benefits for 12 months for Mr. Graham, Ms. Palmer, Ms. Vieira, and Mr. Jafarieh. In the case of Mr. Witter, benefits will be provided for 24 months.

(6) | In the instance of a termination by the Company without cause or by the executive for good reason, $15,000 of outplacement services will be provided.

Upon eligible retirement, these awards generally continue to vest based on their original terms. As of December 31, 2025, none of the NEOs were retirement eligible, except for Ms. Vieira. As a result, only awards granted to Ms. Vieira in 2023, 2024, and 2025 are eligible for vesting in the event of retirement.

(9) | For equity vesting—unvested equity awards accelerate upon termination by death or disability (as defined in the 2021 Plan or the Predecessor Plan, as applicable). Amounts shown are the value of RSU awards that would vest for each individual on December 31, 2025, based on the closing market price of the Company’s Common Stock on that date of $27.06.

2025 Pay Ratio Disclosure

Pay Ratio

|  | In accordance with the requirements of Section 953(b) of Dodd-Frank and Item 402(u) of Regulation S-K (which we collectively refer to as the “Pay Ratio Rule”), we are providing the following estimated information for 2025: • the annual total compensation of the median employee excluding our CEO (the “Median Employee”) was $110,230; • the annual total compensation of our CEO was $11,261,733; and • the ratio of these two amounts was 102 to 1. We believe that this ratio is a reasonable estimate calculated in a manner consistent with the requirements of the Pay Ratio Rule. SEC rules for identifying the Median Employee and calculating the pay ratio allow companies to apply various methodologies and assumptions and, as a result, the pay ratio reported by the Company may not be comparable to the pay ratio reported by other companies, including those within our peer groups and industry. |  |

Methodology for Identifying our Median Employee

Pursuant to the SEC rules, a company must identify its Median Employee once every three years, unless there has been a change in its employee population or employee compensation arrangements such that the company reasonably believes the change would result in a significant change in the CEO pay ratio. After a detailed review, we determined that it is appropriate to use the same Median Employee for the second year in a row because there have not been changes to our employee population or employee compensation arrangements that we believe would result in a significant change to the CEO pay ratio.

Employee Population

We selected December 31 as the measurement date, which is within the last three months of the year, upon which we would identify the Median Employee in order to measure the Median Employee’s compensation consistent with how the CEO’s pay is presented in this proxy statement. As of December 31, 2025, our employee population consisted of approximately 1,800 full-time, part-time, seasonal, and temporary employees.

Determining our Median Employee

We use base pay and bonus (base pay included all wages paid during the year, plus any equivalent paid time off, including leave pay, military pay, volunteer pay, and holiday pay, and the bonus calculation included any cash incentive payment) as the consistently applied compensation measure (the “CACM”) to identify our Median Employee from our total employee population and did not make any cost-of-living adjustments in identifying our Median Employee.

Our Median Employee

Using the methodologies described above, including the CACM, we determined that our Median Employee is appropriate to use for the second year in a row. Our Median Employee is a full-time, salaried employee located in the United States who provides support in our commercial business.

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

Once we identified our Median Employee, we calculated such employee’s annual total compensation for 2025 using the same methodology used for purposes of determining the annual total compensation of NEOs for 2025 (as set forth in the 2025 Summary Compensation Table on page 49 of this proxy statement), adjusted to include the cost to the Company in 2025 of specified employee benefits that are provided on a nondiscriminatory basis, including employee assistance benefits (including tuition reimbursements and participation in a medical and wellness assistance program).

The CEO’s annual total compensation for 2025 for purposes of the CEO Pay Ratio Rule is equal to the amount reported in the “Total” column in the 2025 Summary Compensation Table, adjusted, to the extent applicable, in a similar manner as the annual total compensation of our Median Employee.

(1) | The dollar amounts reported in column (b) are the amounts of total compensation reported for Mr. Witter for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to the Summary Compensation Table as set forth on page 49 of this proxy statement, on page 54 of the prior year’s proxy statement filed with the SEC on April 28, 2025, and on page 53 of the proxy statement filed with the SEC on April 26, 2024.

(2) | The dollar amounts reported in columns (c) and (e) represent the amount of “compensation actually paid” (otherwise known as CAP), adjusted as follows in the table below, as determined in accordance with SEC rules. None of the equity awards held by NEOs were forfeited during the preceding five years; therefore, no amounts are reported for forfeited awards. CAP does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules. We do not have a defined benefit plan, so no adjustment for pension benefits is included in the table below. Fair values set forth in the table below are computed in accordance with ASC 718 as of the end of the respective fiscal year, other than fair values of the awards that vest in the covered year, which are valued as of the applicable vesting date. Similarly, no adjustment is made for dividends because the amount associated with such dividends are reflected in the fair value of the award for the covered fiscal year. The reconciliation from the Summary Compensation Table to CAP for fiscal year 2021 through fiscal year 2022 can be found in the proxy statement filed with the SEC on April 27, 2023. The reconciliation from the Summary Compensation Table to CAP for fiscal year 2023 can be found in the proxy statement filed with the SEC on April 26, 2024. The reconciliation from the Summary Compensation Table to CAP for fiscal year 2024 can be found in the proxy statement filed with the SEC on April 28, 2025. The reconciliation from the Summary Compensation Table to CAP for fiscal year 2025 is summarized in the table below.

| (b) | The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” column in the Summary Compensation Table for the applicable year.

|  | The recalculated value of equity awards for each applicable year includes the addition (or subtraction, as applicable) of the following:

| (i) | the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year;

| (ii) | the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year;

| (iii) | for awards that are granted in prior years and vest in the applicable year, the change in the fair value as of the vesting date from the beginning of the applicable year;

| (iv) | the vesting date fair value of any equity awards that are granted and vest in the applicable year;

| (v) | awards that fail to meet vesting conditions during the fiscal year and are no longer outstanding; and

| (vi) | value of dividends not otherwise captured in the calculation of each Fair Value used to calculate CAP.

|  | While the equity awards disclosed in the Summary Compensation Table are based on the grant date fair values computed in accordance with FASB ASC Topic 718, the equity award values disclosed pursuant to CAP in the table above are calculated in the following manner:

| • |  | The stock prices used to calculate the figures in columns (i) and (ii) in the above table are as follows: $27.58 on December 31, 2024 and $27.06 on December 31, 2025. The stock prices used to calculate the figures in column (iii) in the above table are based on the closing prices on the vesting dates of the applicable awards.

| • |  | The valuation assumptions and processes used to recalculate fair values did not materially differ from those disclosed at the time of grant.

| (c) | “Compensation actually paid” does not necessarily represent cash and/or equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules.

(3) | The dollar amounts reported in column (d) are the average amounts of total compensation reported for the other Named Executive Officers for each corresponding year in the “Total” column of the Summary Compensation Table. Refer to the Summary Compensation Table as set forth on page 49 of this proxy statement, on page 54 of the prior year’s proxy statement filed with the SEC on April 28, 2025, and on page 53 of the proxy statement filed with the SEC on April 26, 2024. For each of 2021, 2022, 2023, 2024, and 2025, the other NEOs were:

2021 |  | Steven J. McGarry, Kerri A. Palmer, Donna F. Vieira, Daniel P. Kennedy

(4) | TSR is determined based on the value of an initial fixed investment of $100 measured from December 31, 2020. The TSR peer group consists of the S&P Supercomposite Consumer Finance Sub-Industry Index, which is used for our Stock Performance presentation set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

(5) | Our Company-Selected Measure is Relative TSR consistent with the peer group used in the PSU metric under our annual Long-Term Incentive Program. For illustrative purposes, calculations within this column are based on 1-year measurements (as opposed to the 3-year relative TSR performance period regarding the Company’s PSUs). For purposes of relative TSR, the peer group used in the PSU metric under our annual Long-Term Incentive Program consists of: (i) the S&P Supercomposite Consumer Finance Sub-Industry Index and (ii) the S&P 400 Regional Bank Sub-Industry Index.

PAY VERSUS PERFORMANCE
Relationship Between “Compensation Actually Paid” and Performance Measures
The following graphs illustrate the alignment between compensation actually paid to the NEOs and the Company’s performance, consistent with our compensation philosophy as described in the CD&A on page 30. Specifically, a large portion of the NEOs’ compensation is reliant on TSR and as such the CEO and Other NEOs’ “compensation actually paid” each year was aligned with our TSR performance and increased when our TSR performance increased but declined when our TSR performance declined. The charts below show, for the past five years, the relationship of the Company’s TSR relative to the Company’s TSR peer group as well as the relationship between the CEO and Other NEOs’ “compensation actually paid” and (i) the Company’s TSR; (ii) the Company’s net income; and (iii) the

Director Compensation

Our director compensation program is designed to reasonably compensate non-employee directors for work required for a company of our size and complexity and to align the directors’ interests with those of the Company’s stockholders. The Compensation Committee reviews the compensation level of non-employee directors on an annual basis and makes recommendations to the Board of Directors. Pursuant to the 2021 Plan, non-employee directors may not be granted, during any calendar year, equity and/or cash compensation resulting in aggregate total compensation determined on the grant date to be in excess of $750,000.

(2) | Each of the non-employee directors elected to the Board of Directors at the 2025 Annual Meeting received a restricted stock award on June 17, 2025, which vests in full upon the 2026 Annual Meeting. The grant date fair market value for each share of restricted stock granted on June 17, 2025 to directors is based on the closing market price of our stock on June 17, 2025, which was $31.24. Additional details on accounting for stock-based compensation can be found in Note 2, “Significant Accounting Policies,” and Note 15, “Stock-Based Compensation Plans and Arrangements,” of Sallie Mae’s Consolidated Financial Statements contained in the Company’s 2025 Form 10-K.

Mr. Blackley, Mr. Lavelle, and Mr. Manvitz each elected this option. Such grants of Common Stock in lieu of cash were awarded on March 19, 2025 and June 18, 2025, based on the closing market price of the Company’s Common Stock on those particular days, $30.11 and $31.70, respectively. After the Company’s 2025 Annual Meeting, non-employee directors were given the option to receive shares of Common Stock in lieu of cash pertaining to the Board of Directors’ annual cash retainer and, as applicable, any retainer received for service as Board Chair, committee chair, or member of any committee of the Board of Directors. Mr. Blackley, Mr. Greig, and Mr. Manvitz each elected this option. Such grants of Common Stock in lieu of cash were awarded on September 17, 2025 and December 17, 2025 based on the closing market price of the Company’s Common Stock on those particular days, $28.12 and $26.88, respectively.

Director Compensation Elements

The following table highlights the material elements of the 2025 director compensation program:

Membership/Retainer* |  | Annual Cash Retainer
Board of Directors Retainer |  | $ 70,000
Board Chair Retainer |  | $125,000
Committee Chair Retainer |  |
• Audit Committee |  | $ 30,000
• Compensation Committee |  | $ 25,000
• Nominations and Governance Committee |  | $ 20,000
• Financial Risk Committee |  | $ 20,000
• Operational and Compliance Risk Committee |  | $ 20,000

• Audit Committee |  | $ 15,000
• Compensation Committee |  | $ 12,500
• Nominations and Governance Committee |  | $ 10,000
• Financial Risk Committee |  | $ 10,000
• Operational and Compliance Risk Committee |  | $ 10,000

* | Certain directors elected to receive shares of Common Stock in lieu of cash pertaining to their annual cash retainer and respective committee fees, paid quarterly.

In addition to the committees above, some of the non-employee directors are also members of our Preferred Stock Committee. No fees were paid in 2025 in connection with this committee. All members of the Board of Directors also serve as members of the board of directors of the Bank and its committees and receive no separate compensation for that service.

In addition to the cash retainers set forth above, non-employee directors each received $165,000 in restricted stock awards, which resulted in a grant date fair value of $164,978. These restricted stock awards will vest and become transferable upon the Company’s 2026 Annual Meeting. These awards will be forfeited if the grantee ceases to be a member of the Board of Directors prior to the vesting event for any reason other than death, disability, or change of control.

The Company reimburses directors for any out-of-pocket expenses incurred in connection with service as a director.

Director compensation is determined by the Board of Directors, and the Compensation Committee makes recommendations to the Board of Directors based on periodic benchmarking assessments and advice received from the Compensation Committee’s independent compensation consultant. In making recommendations to the Board of Directors, the Compensation Committee considers the competitive positioning of the aggregate and individual components of compensation, as well as the mix of pay and structure versus both direct competitors and other comparable companies. The Compensation Committee also considers the unique skill set required to serve on our Board of Directors and the time commitment associated with preparation for and attendance at meetings of the Board of Directors and its committees as well as external commitments, such as engagement with our stockholders and regulators.

Stock Ownership Guidelines

The Company maintains stock ownership guidelines for non-employee directors. Under the stock ownership guidelines, each non-employee director is expected, within five years of initial election to the Board of Directors, to own Common Stock with a value equivalent to five times their annual cash retainer for serving on our Board of Directors. As of December 31, 2025, all non-employee directors were in compliance with the stock ownership guidelines or are expected to achieve compliance within the applicable five-year period.

Other Compensation

The Company provides non-employee directors with Company-paid business travel accident insurance, as well as annual premiums paid to provide a life insurance benefit.

Deferred Compensation Plan

Under the Company’s Deferred Compensation Plan for Directors (“Director Deferral Plan”), non-employee directors may elect annually to defer receipt of all or a percentage of their annual retainer. Deferrals are credited with earnings based on the performance of certain investment funds selected by the participant. Deferrals are fully vested at all times and are payable in cash (in lump sum or in installments at the election of the director) or Company stock upon termination of the director’s service on the Board of Directors (except for hardship withdrawals in limited circumstances). During 2025, none of the non-employee directors actively participated in the Director Deferral Plan.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16 of the Exchange Act requires Sallie Mae’s executive officers and directors, as well as persons who beneficially own more than 10 percent of the Common Stock, to file reports on their holdings of and transactions in our Common Stock. Based solely on a review of the copies of such forms in the Company’s possession and on written representations from reporting persons, the Company believes during the fiscal year 2025 all required reports were filed in a timely manner.

Other Matters

Other Matters for the 2026 Annual Meeting

As of the date of this proxy statement, there are no matters the Board of Directors intends to present for a vote at the Annual Meeting other than the business items discussed in this proxy statement. In addition, Sallie Mae has not been notified of any other business proposed to be presented at the Annual Meeting. If other matters now unknown to the Board of Directors come before the Annual Meeting, the proxy given by a stockholder electronically, telephonically, or on a proxy card gives discretionary authority to the persons named by Sallie Mae to serve as proxies to vote such stockholder’s shares on any such matters in accordance with their best judgment.

Stockholder Proposals for the 2027 Annual Meeting

A stockholder who intends to introduce a proposal for consideration at the Company’s 2027 annual meeting may seek to have that proposal and a statement in support of the proposal included in the Company’s 2027 proxy statement if the proposal relates to a subject that is permitted under Rule 14a-8 of the Exchange Act (“Rule 14a-8”). To be considered for inclusion, the proposal and supporting statement must be received by the Company no later than January 4, 2027 at the office of the Corporate Secretary at the Company’s principal executive offices, located at 300 Continental Drive, Newark, Delaware 19713, and must satisfy the other requirements of Rule 14a-8. The submission of a stockholder proposal does not guarantee it will be included in the Company’s 2027 proxy statement.

The Company’s Bylaws provide that a stockholder may otherwise propose business for consideration or nominate persons for election to the Board of Directors, in compliance with federal proxy rules, applicable state law and other legal requirements, and without seeking to have the proposal included in our proxy statement pursuant to Rule 14a-8. The Company’s Bylaws provide that any such proposals or nominations and any nominations to be included in the Company’s proxy statement pursuant to proxy access provisions of our Bylaws for our 2027 annual meeting must be received by the Company not earlier than the close of business on February 16, 2027, nor later than the close of business on March 18, 2027. All notices must satisfy the other requirements in the Company’s Bylaws applicable to such proposals, nominations, and proxy access. If a stockholder fails to meet these deadlines or fails to comply with the requirements of Rule 14a-4(c) under the Exchange Act, the Company may, in certain circumstances, exercise discretionary voting authority under proxies it solicits to vote on any such proposal.

In addition to complying with the advance notice provisions of our Bylaws, stockholders who intend to solicit proxies in support of director nominees, other than the Company’s nominees, must also comply with the additional requirements of Rule 14a-19, which requires, among other things, that a stockholder provide notice that includes certain information, which notice must be postmarked or transmitted electronically to the Company’s Corporate Secretary no later than April 19, 2027*.

* | April 17, 2027 is 60 calendar days prior to the anniversary of the 2026 annual meeting date, but such date falls on a Saturday. Accordingly, the deadline is extended to Monday, April 19, 2027.

OTHER MATTERS

Solicitation Costs

All expenses in connection with the solicitation of proxies for the Annual Meeting will be paid by us. In addition, officers, directors, regular employees, or other agents of the Company may solicit proxies by telephone, telefax, personal calls, or other electronic means. We will request banks, brokers, custodians, and other nominees in whose names shares are registered to furnish to the beneficial owners of the Company’s Common Stock Notices of Availability of the materials related to the Annual Meeting, and including, if so requested by the beneficial owners, paper copies of the 2025 Form 10-K, this proxy statement, and the proxy card and, upon request, we will reimburse such registered holders for their out-of-pocket and reasonable expenses in connection therewith.

Householding

To reduce the expense of delivering duplicate proxy materials to stockholders who may have more than one account holding stock but share the same address, the Company adopted a procedure approved by the SEC called “householding.” Under this procedure, certain registered stockholders who have the same address and last name, and who do not participate in electronic delivery of proxy materials, will receive one copy of the Notice of Availability and, as applicable, any additional proxy materials that are delivered until such time as one or more of these stockholders notifies us they want to receive separate copies. We hereby undertake to deliver promptly, upon written or oral request, a separate copy of the Notice of Availability or proxy materials, as the case may be, to a stockholder at a shared address to which a single copy of the document(s) was delivered. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If you are a registered stockholder and would like to have separate copies of the Notice of Availability or proxy materials mailed to you in the future, or you would like to have a single copy of the Notice of Availability or proxy materials mailed to you in the future, you must submit a request in writing to Broadridge Financial Solutions, Inc., Householding Department, 51 Mercedes Way, Edgewood, New York 11717 or by calling 1-866-540-7095. If you are a beneficial stockholder, please contact your bank or broker to opt in or out of householding.

However, please note if you want to receive a separate proxy card or vote instruction form or other proxy materials for purposes of this year’s Annual Meeting, you should follow the instructions included in the Notice of Availability that was sent to you and we will deliver, promptly upon written or oral request, separate copies of the proxy materials for this year’s Annual Meeting.

Questions and Answers About the Annual Meeting and Voting

Who may vote? Only stockholders who owned shares of our Common Stock, par value $.20 per share, at the close of business on April 20, 2026, the record date for the Annual Meeting, are entitled to notice of, and to vote at, the Annual Meeting. Sallie Mae’s Common Stock is listed on NASDAQ under the symbol “SLM.” On April 20, 2026, 188,592,995 shares of Common Stock were outstanding and eligible to be voted.

Why did I receive a “Notice Regarding the Availability of Proxy Materials”? We are furnishing proxy materials to our stockholders primarily via the Internet, instead of mailing printed copies of those materials to each stockholder. By doing so, we save costs and reduce the environmental impact of the Annual Meeting. On or about May 4, 2026, we mail a Notice Regarding the Availability of Proxy Materials (“Notice of Availability”) to the Company’s stockholders. The Notice of Availability contains instructions on how to access the proxy materials and vote online or vote by telephone. The Notice of Availability also contains a 16-digit control number that you will need to vote your shares. If you previously chose to receive our proxy materials electronically, you will continue to receive access to these materials via an email that will provide electronic links to these documents unless you elect otherwise.

How do I request paper copies of the proxy materials? You may request paper copies of the proxy materials for the Annual Meeting by following the instructions listed in the Notice of Availability, at www.proxyvote.com, by telephoning 1-800-579-1639, or by sending an email to sendmaterial@proxyvote.com.

What is the difference between holding shares as a beneficial owner in street name and as a stockholder of record? If your shares are held in street name through a broker, bank, trustee, or other nominee, you are considered the beneficial owner of shares held in street name. As the beneficial owner, you have the right to direct your broker, bank, trustee, or other nominee how to vote your shares. Without your voting instructions, your broker, bank, trustee, or other nominee may only vote your shares on routine matters. Routine matters DO NOT include Proposals 1, and 2 but do include Proposal 3 (relating to the ratification of the appointment of the independent registered public accounting firm). For non-routine matters, your shares will not be voted without your specific voting instructions. Accordingly, Sallie Mae encourages you to vote your shares.

If your shares are registered directly in your name with our transfer agent, Computershare, you are considered to be a stockholder of record with respect to those shares. As a stockholder of record, you have the right to grant your voting proxy directly to Sallie Mae or to a third party, or to vote at the Annual Meeting.

How do I vote? We encourage stockholders to vote in advance of the Annual Meeting, even if you plan to attend the Annual Meeting. You may vote in one of the following ways:

• |  | By Internet prior to the meeting. You may vote electronically via the Internet at www.proxyvote.com. Votes submitted via the Internet must be received by 11:59 p.m., Eastern Daylight Time, on June 15, 2026. Please have your Notice of Availability or proxy card available when you log on.

• |  | By Telephone. If you wish to vote by telephone, you may call the toll-free telephone number on the Notice of Availability or your proxy card, which is available 24-hours a day, and follow the prerecorded instructions. Please have your Notice of Availability or proxy card available when you call. If you hold your shares in street name, your broker, bank, trustee, or other nominee may provide you additional instructions regarding voting your shares by telephone. Votes submitted telephonically must be received by 11:59 p.m., Eastern Daylight Time, on June 15, 2026.

• |  | By Internet during the meeting. You may vote electronically via the Internet at www.virtualshareholdermeeting.com/SLM2026.

• |  | By Mail. If you receive a paper copy of the proxy materials, you will need to mark, sign, and date the proxy card or the voting instruction form and return it in the prepaid return envelope provided. Your proxy card or voting instruction form must be received no later than the date indicated on the proxy card or voting instruction form.

What if I hold my shares in street name and I do not provide my broker, bank, trustee, or other nominee with instructions about how to vote my shares? You may instruct your broker, bank, trustee, or other nominee about how they may vote your shares using the methods described above. If you do not provide voting instructions to the firm that holds your shares prior to the Annual Meeting, the firm has discretion to vote your shares with respect to Proposal 3 on the proxy card (relating to the ratification of the appointment of the independent registered public accounting firm), which is considered a routine matter. However, the firm will not have discretion to vote your shares with respect to Proposals 1, and 2 on the proxy card, as these are each considered to be a non-routine matter. You are encouraged to participate in the election of directors and vote on all of the proposals by returning your voting instructions to your broker, bank, trustee, or other nominee.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING AND VOTING

How do proxies work? The Board of Directors is requesting your proxy. Giving your proxy means you authorize the persons named as proxies therein to vote your shares at the Annual Meeting in the manner you specify in your proxy (or to exercise their discretion as described herein). If you hold your shares as a record holder and sign and return a proxy card but do not specify how to vote on a proposal, the persons named as proxies will vote your shares in accordance with the Board of Directors’ recommendations. The Board of Directors has recommended that stockholders vote:

• |  | “FOR” the election of each of the director nominees named in Proposal 1;

• |  | “FOR” advisory approval of Sallie Mae’s executive compensation set forth in Proposal 2; and

• |  | “FOR” ratification of the appointment of Sallie Mae’s independent registered public accounting firm set forth in Proposal 3.

In the absence of voting instructions to the contrary, shares of Common Stock represented by validly executed proxies will be voted in accordance with the foregoing recommendations. Sallie Mae does not know of any other matters to be presented at the Annual Meeting as of the date of this proxy statement. If other matters now unknown to the Board of Directors come before the Annual Meeting, the proxy given by you electronically, telephonically, or on a proxy card gives discretionary authority to the persons named by Sallie Mae to serve as proxies to vote your shares on any such matters in accordance with their best judgment.

Can I change my vote? Yes. If you hold your shares as a record holder, you may revoke your proxy or change your vote at any time prior to the final tallying of votes by:

• |  | Delivering a written notice of revocation to Sallie Mae’s Corporate Secretary at the Office of the Corporate Secretary, 300 Continental Drive, Newark, Delaware 19713;

• |  | Submitting another timely vote via the Internet, by telephone, or by mailing a new proxy (following the instructions listed under the “How do I vote?” section); or

• |  | Voting at the Annual Meeting live via the Internet at www.virtualshareholdermeeting.com/SLM2026.

If your shares are held in street name, contact your broker, bank, trustee, or nominee for instructions on how to revoke or change your voting instructions.

What constitutes a quorum? A quorum is necessary to transact business at the Annual Meeting. A quorum exists if the holders of a majority in voting power of the Common Stock issued and outstanding and entitled to vote at the Annual Meeting are present in person or represented by proxy, including proxies on which abstentions (withholding authority to vote) are indicated. Abstentions and broker non-votes will be counted in determining whether a quorum exists. Virtual attendance at the Annual Meeting constitutes presence for purposes of a quorum.

Who will count the vote? Votes will be tabulated by our Chief Legal, Government Affairs, and Communications Officer, who will act as the Inspector of Elections at the Annual Meeting.

Who can attend the Annual Meeting? Only holders of Common Stock as of the record date, April 20, 2026, or duly appointed proxies, may attend the Annual Meeting.

What do I need to attend the Annual Meeting? You may attend the Annual Meeting live via the Internet at www.virtualshareholdermeeting.com/SLM2026. Stockholders will need the 16-digit control number provided on their proxy card, voting instruction form, or notice. We suggest you log in at least 15 minutes before the start of the meeting.

Can I ask questions at the Annual Meeting? Stockholders as of our record date, April 20, 2026, will have an opportunity to submit questions live via the Internet during the meeting.

|  | How to Participate in the Annual Meeting |  | Online: 1.  Visit www.virtualshareholdermeeting.com/SLM2026 and 2.  Enter the 16-digit control number included on your Notice Regarding the Availability of Proxy Materials or your proxy card (if you received a printed copy of the proxy materials), or on the instructions that accompanied your proxy materials. The meeting will begin promptly at 1:00 p.m., Eastern Daylight Time, on June 16, 2026. We suggest you log in to the meeting platform at least 15 minutes before the start of the meeting. |  |
