There can be no assurance that future developments affecting the Company will be the same as those anticipated by management. The Company cautions readers that a number of important factors could cause actual results to differ materially from those expressed in, or implied or projected by, such forward-looking statements.

We could also be affected by, among other things: changes in our funding costs and availability; reductions to our credit ratings; cybersecurity incidents, cyberattacks, and other failures or breaches of our operating systems or infrastructure, including those of third-party vendors; the societal, demographic, business, and legislative/regulatory impacts of pandemics, other public health crises, severe weather events, and/or natural disasters; damage to our reputation; risks associated with restructuring initiatives, including failures to successfully implement cost-cutting programs and the adverse effects of such initiatives on our business; changes in the demand for educational financing or in financing preferences of lenders, educational institutions, students, and their families, including changes as a result of new limits on, or reductions in, funding that certain educational institutions receive from the Federal government; changes in law and regulations with respect to the student lending business and financial institutions generally; changes in banking rules and regulations, including increased capital requirements; increased competition from banks and other consumer lenders; the creditworthiness of our customers, or any change related thereto; changes in the general interest rate environment, including the rate relationships among relevant money-market instruments and those of our earning assets versus our funding arrangements; rates of prepayments on the loans owned by us; changes in general economic conditions, including as a result of the impact of tariffs or trade wars or other current initiatives of the Federal government, that may impact the demand for student loans and the risk of default of outstanding loans; our ability to successfully effectuate any acquisitions; and other strategic initiatives. The preparation of our consolidated financial statements also requires management to make certain estimates and assumptions, including estimates and assumptions about future events. These estimates or assumptions may prove to be incorrect.

We calculate and report our Return on Common Equity (“ROCE”) as the ratio of (a) GAAP net income (loss) attributable to SLM Corporation common stock numerator (annualized) to (b) the net denominator, which consists of GAAP total average equity less total average preferred stock. 3. We calculate the percentage of loans in an extended grace period as the ratio of (a) Private Education Loans in forbearance in an extended grace period numerator to (b) Private Education Loans in repayment and forbearance denominator. An extended grace period aligns with The Office of the Comptroller of the Currency definition of an additional, consecutive, one-time period during which no payment is required for up to six months after the initial grace period. We typically grant this extended grace period to customers who may be having difficulty finding employment before the full principal and interest repayment period starts or once it has begun. 4. We calculate the percentage of loans in hardship and other forbearances as the ratio of (a) Private Education Loans in hardship and other forbearances (excluding loans in an extended grace period and delinquent loans in disaster forbearance) numerator to (b) Private Education Loans in repayment and forbearance denominator. If the customer is in financial hardship, we work with the customer and/or cosigner and identify any available alternative arrangements designed to reduce monthly payment obligations, which may include a short-term hardship forbearance. 5. Source: Enterval CBA Report (https://www.enterval.com/) for full-year 2024 as of December 2024. 6. Based on internal Company statistics. 7. Statistic considers portfolio Private Education Loans only and is presented as an annualized number, as of June 30, 2025. 8. Represents the higher credit score of the cosigner or the borrower. 9. By year of origination approval. 10. The Company’s expectation and ability to pay a quarterly cash dividend on its common stock in the future will be subject to the determination by, and discretion of, the Company’s Board of Directors, and any determination by the Board will be based on an evaluation of the Company’s earnings, financial condition and requirements, business conditions, capital allocation determinations, and other factors, risks and uncertainties. 11. Enrollment data from NCES Digest of education statistics (various tables). Cost data included from College Board 2024 Trends in College Pricing and 2024 Trends in Student Aid. Total market is based on internal company statistics that include inputs from government projections. These projections were updated in the fourth quarter of 2024. 12. Smart Option loans considered in ‘P&I Repayment’ only if borrowers are subject to full principal and interest payments on the loan. 13. Overcollateralization for Class A & B bonds. 14. Estimated based on a variety of assumptions concerning loan repayment behavior. Actual prepayment rate may vary significantly from estimates. 15. We calculate and report our Return on Assets (“ROA”) as the ratio of (a) GAAP net income (loss) numerator (annualized) to (b) the GAAP total average assets denominator. 16. For purposes of this slide, loans in repayment include loans making interest only or fixed payments, as well as loans that have entered full principal and interest repayment status after any applicable grace period (but do not include loans in the “loans in forbearance” metric). 17. For purposes of this slide, loans in forbearance include loans for customers who have requested extension of grace period generally during employment transition or who have temporarily ceased making full payments due to hardship or other factors (other than delinquent loans in disaster forbearance), consistent with established loan program servicing policies and procedures. 18. The period of delinquency is based on the number of days scheduled payments are contractually past due. Footnotes
