Proposal 4—

Ratification of the Appointment of the Independent Registered Public Accounting Firm

Sallie Mae’s independent registered public accounting firm, KPMG LLP (“KPMG”), is selected by the Audit Committee of Sallie Mae’s Board of Directors (the “Audit Committee”). The Audit Committee has engaged KPMG as Sallie Mae’s independent registered public accounting firm for the fiscal year ending December 31, 2023. 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 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 2023 if, in its discretion, it determines such a change would be in the Company’s best interests.

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:

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 By-Laws, embody the following governance practices, among others:

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 first woman to chair 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 and stockholders. Mr. Witter, our CEO, serves as a member of the Board of Directors. The Board of Directors believes an independent director is best situated to serve as Board Chair as an effective counterbalance to management and our CEO, who also serves on the Board of Directors. By separating the CEO role from the Board Chair role, the Company is currently 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 By-Laws, 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 conform to the independence requirements 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 2022 and all nominees standing for election at the Annual Meeting, other than Mr. Witter, our CEO, are independent of Sallie Mae.

Each member of the Board of Directors’ Audit, Nominations and Governance, and Compensation Committees is independent within the meaning of the NASDAQ listing standards, 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 Diversity

Our Board of Directors believes diversity is important and seeks representation across a range of attributes, including gender, race, ethnicity, and professional experience, and regularly assesses diversity when identifying and evaluating director candidates. As of December 31, 2022, our Board of Directors consisted of the following:

Board Skills and Experience

Board, Committee, and Annual Meeting Attendance

Our Board of Directors met 15 times in 2022. Each of the incumbent directors attended at least 75 percent of the total number of meetings of the Board of Directors and committees on which he or she served. Directors are expected to attend the Annual Meeting, and 11 out of 12 of the then-serving members of the Board of Directors attended the Annual Meeting in June 2022. Mr. Frank C. Puleo retired on June 21, 2022, the date of the 2022 Annual Meeting. Accordingly, he did not stand for re-election and did not attend the 2022 Annual Meeting.

Roles of the Board and Its Committees

The Board of Directors has established the following standing committees to assist in its oversight responsibilities: Audit; Compensation; Nominations and Governance; Financial Risk; Operational and Compliance Risk; and Preferred Stock. Each committee is governed by a Board-approved written charter, which is evaluated annually and sets forth the respective committee’s functions, responsibilities, and delegated authority. Membership of each of the committees is established on an annual basis.

Committee charters are available at www.salliemae.com/investors/corporate-governance/. Stockholders may obtain a written copy of any and all committee charters by contacting the Corporate Secretary at corporatesecretary@salliemae.com or SLM Corporation, 300 Continental Drive, Newark, Delaware 19713.

Risk Oversight

The Board of Directors and its committees oversee Sallie Mae’s overall strategic direction, including setting risk management philosophy, tolerance and parameters, and establishing procedures for assessing the risks of each business line as well as the risk management practices the management team develops and utilizes. Management escalates to the Board of Directors and/or its committees any significant departures from established tolerances and parameters and reviews new and 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:

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. The 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 that reflects gender, race, ethnic, and geographic diversity. The minimum qualifications and attributes the Nominations and Governance Committee believes a director nominee must possess include:

To recommend a candidate, stockholders should send, in writing, the candidate’s name, credentials, contact information, and his or her 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 his or her contact information and a statement of his or her share ownership. The nomination deadline for the 2023 Annual Meeting has now closed. A stockholder wishing to nominate a candidate for the 2024 Annual Meeting must comply with the notice and other requirements in the By-Laws as described under “Stockholder Proposals for the 2024 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 involving Sallie Mae in excess of $120,000 in any year 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. Moreover, 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 then 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 take into account 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.

Environmental, Social, and Governance Practices

In conducting our business, we continually pursue practices we believe will drive sustainable, long-term growth and profitability. Such “environmental, social, and governance” or “ESG” practices may mean different things to different investors and stakeholders and to the organizations that evaluate and rate ESG practices. Our ESG practices are shaped by our mission—to power confidence as students begin their unique journeys. In April 2023, we released our annual ESG report, discussing our commitment to ESG practices. For a full discussion, please read our ESG report at www.salliemae.com/esg. Neither the report nor our website is incorporated by reference in this proxy statement.

Human Capital Empowerment and Talent Development

We believe in a just and inclusive, values-based, mission-led culture that inspires commitment and drives performance. Our human capital strategy is focused on the attraction, development, empowerment, recognition, and rewarding of team members as they bring our mission to life.

We strive to create a diverse culture of inclusion and an environment that encourages and reinforces mutual trust, makes it safe to express thoughts, ideas and concerns, and connects and embraces diverse backgrounds and perspectives to power and fuel our mission. We believe such a diverse and inclusive workforce can lead to a more effective company.

We are focused on providing a total compensation package that enables us to attract, motivate, and retain our employees to help drive our business forward. Our benefits package includes company contributions to the 401(k) plan, educational assistance to our team members and their dependents, flexible work arrangements, and other comprehensive health and welfare programs. We also believe in paying competitive market wages, which is why we established $20/hour as our minimum starting rate for all positions in 2021.

As of December 31, 2022, we had approximately 1,700 team members, all located in the United States. We believe an engaged workforce leads to a more innovative, productive, and profitable company. For this reason, we measure employee engagement through culture surveys. These culture surveys provide insights we use to create an environment in which team members thrive and bring their full selves to work.

Ensuring the safety and well-being of our team members continued to be a priority during the COVID-19 pandemic. In March 2020, we enacted a robust business continuity plan, including remote working capabilities for all team members. We further adapted to the changing environment in 2021, and now offer remote, in-office, and hybrid options so our team may work in a manner best suited for them and their positions. We continue to provide team members with the tools and resources necessary to support their success and drive performance of the Company.

Our team members are involved in the communities in which they live and work through the Sallie Mae Employee Volunteer Program and the Sallie Mae Employee Matching Gift Program. In 2022, our team members volunteered 1,928 hours of their time through our community engagement programs. We also provide matching gifts for team members to support the interests and needs of them and their communities.

Corporate Governance

Sallie Mae’s Board of Directors, executive leaders, team members, and business partners are committed to operating under sound principles of corporate governance. We believe maintaining high standards of accountability and transparency are fundamental for the long-term success of our business. Our corporate governance structure ensures robust Board and management responsibility, responsiveness to our stockholders, and responsible decision-making. Our overarching code of conduct, corporate governance policies, Board committee charters, certificate of incorporation, and By-Laws form the framework of governance at Sallie Mae. Since the formation of the Company, we have attracted and built a strong, qualified, and diverse Board of Directors whose members have expertise relevant to our business and are deeply committed to operating ethically and with integrity. Eleven members of the Board are independent directors, including Ms. Franke, the first woman to serve as Board Chair in the Company’s history.

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. We comply with federal, state, and local lobbying registration and disclosure requirements. We work 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, we have 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. Our involvement with industry associations is limited to those associations comprised of financial institutions with similar interests.

CORPORATE GOVERNANCE

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, we 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 their views on policy matters that impact Sallie Mae and our employees, their committee or leadership role, and representation of Sallie Mae facilities and employees.

Our PAC contributions are published on the FEC website.
