8 Federal Student Loan Reform Update On July 4th, 2025, H.R.1., which contains major federal student lending reforms, was signed into law. Setting reasonable limits on parent and graduate lending better aligns these programs with the broader federal loan system and reduces the likelihood the government will lend families more than they can reasonably repay. Eliminates Grad PLUS Loans and Expands Unsubsidized Stafford Loans for Professional Graduate Students - Unsubsidized Stafford loans to graduate students remain capped at $20,500 annually; lowered to $100,000 aggregate. - Unsubsidized Stafford loans to professional graduate students raised to $50,000 annually; $200,000 aggregate. Caps Parent PLUS Loans - Introduces a $20,000 annual cap; added $65,000 aggregate (per student). Leaves Undergraduate Loan Limits at Current Levels All federal student loan program changes are to be effective for new borrowers beginning July 1, 2026, and will not apply to borrowers who begin borrowing prior to that date.

13 1. Originations represent loans that were funded or acquired during the period presented. 2. 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. Represents the higher credit score of the cosigner or the borrower. 6. 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. 7. 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). 8. 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. 9. The period of delinquency is based on the number of days scheduled payments are contractually past due. Footnotes
