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 September 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
