1  Phase 2 Strategy Update  November 19, 2025  v  v  v  v 

 Forward-Looking Statements and Non-GAAP Financial Measures  This presentation contains “forward-looking statements,” within the meaning of the federal securities law, as well as forward-looking projections about our business, prospects and other information, as well as hypothetical business models, which are based on management’s current expectations as of the date of this presentation. Statements that are not historical facts, including statements about our beliefs, opinions, projections or expectations and statements that assume or are dependent upon future events, are forward-looking statements and often contain words such as “expect,” “anticipate,” “assume,” “intend,” “plan,” “project,” “estimate,” “forecast,” “believe,” “seek,” “see,” “will,” “would,” “may,” “could,” “should,” “goals,” “target,” and similar expressions. Such statements involve many risks and uncertainties that could cause our actual results to dier materially from those expressed or implied in our forward-looking statements.  For Navient, these factors include, among other things:  general economic conditions, including the potential impact of inflation and interest rates on Navient and its clients and customers and on the creditworthiness of third parties;  increased defaults on loans held by us;   unanticipated repayment trends on education loans, including prepayments or deferrals resulting from new interpretations or the timing of the execution and implementation of current laws, rules or regulations or future laws, executive orders or other policy initiatives that operate to encourage or require consolidation, abolish existing or create additional income-based repayment or debt forgiveness programs or establish other policies and programs or extensions of previously announced deadlines which may increase or decrease the prepayment rates on education loans and accelerate or slow down the repayment of the bonds in our securitization trusts;  a reduction in our credit ratings;  changes to applicable laws, rules, regulations and government policies and expanded regulatory and governmental oversight;   changes in the general interest rate environment, including the availability of any relevant money-market index rate or the relationship between the relevant money market index rate and the rate at which our assets are priced;  the interest rate characteristics of our assets do not always match those of our funding arrangements;  adverse market conditions or an inability to manage eectively our liquidity risk or access liquidity;  the cost and availability of funding in the capital markets;  our ability to earn Floor Income and our ability to enter into hedges relative to that Floor Income are dependent on the future interest rate environment and therefore is variable;  our use of derivatives exposes us to credit and market risk;  our ability to align continually and eectively our cost structure with our business operations;  our ability to implement our strategic initiatives and realize the projected synergies, cost savings and other benefits of those initiatives;  a failure or breach of our operating systems, infrastructure or information technology systems;  failure by any third party providing us material services or products or a breach or violation of law by one of these third parties;  additional risks inherent in the government contracting environment from our current or previous work with government clients;  acquisitions, strategic initiatives and investments or divestitures that we pursue;  shareholder activism;  reputational risk and social factors; and  the other factors that are described in the “Risk Factors” section of Navient’s Annual Report on Form 10-K for the year ended December 31, 2024, and in our other reports filed with the SEC.  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 and actual results could dier materially. All forward-looking statements contained in this presentation are qualified by these cautionary statements and are made only as of the date of this release. The company does not undertake any obligation to update or revise these forward-looking statements except as required by law.  Navient reports financial results on a GAAP basis and also provides certain non-GAAP performance measures, including Core Earnings, Adjusted Tangible Equity Ratio, and various other non-GAAP financial measures derived from Core Earnings. When compared to GAAP results, Core Earnings exclude the impact of: (1) mark-to-market gains/losses on derivatives; and (2) goodwill and acquired intangible asset amortization and impairment. Navient provides Core Earnings measures because this is what management uses when making management decisions regarding Navient’s performance and the allocation of corporate resources. Navient Core Earnings are not defined terms within GAAP and may not be comparable to similarly titled measures reported by other companies. For certain forward-looking non-GAAP measures, Navient is unable to provide a reconciliation because it is unable to estimate with reasonable certainty the ultimate timing or amount of certain significant items without unreasonable eorts.  For more information on the assumptions underlying the financial snapshots set forth in this presentation, see the Appendix hereto.  2

 Earnest Financial Snapshot – Methodology and Assumptions  26  The Earnest business resides within Navient’s Consumer Lending segment today. As we look forward to Phase 2 of our Strategy Update, we expect that the Earnest business will focus on Student Loan Refinancing (“SLR”) loans and personal loan originations beginning in 2026. As a result, the origination of In-School private loans would be performed by a non-Earnest Navient entity beginning in 2026. The Earnest Financial Snapshot (“Financial Snapshot”) in this presentation is intended to project potential financial fundamentals for the Earnest business after, among others, making adjustments for this proposed change in operations as well as implementing a more optimized funding structure.  The Financial Snapshot is a forward-looking projection for a hypothetical business model. The Financial Snapshot is meant for illustrative purposes only. It is not reflective of historical GAAP results nor intended to be a forecast of Earnest’s results. The Financial Snapshot is based on forecasted 2025 results (actual results through September 30, 2025 plus a projection of fourth quarter 2025 results) prepared on a Core Earnings & segment basis with certain additional adjustments.  The following summarizes key assumptions and adjustments reflected in the Financial Snapshot that are dierent from how the Earnest business is reflected currently as a component of Navient’s Consumer Lending segment to illustrate possibilities for the Earnest business if certain operational and financing changes are made within the business:  Earnest has and will continue to originate In-School private loans through December 31, 2025. Subsequently that function is expected be performed by a non-Earnest Navient entity. The 2025 forecast continues to include the Net Interest Income of In-School private loans that were originated through December 31, 2025 as those loans are expected to be continued to be reflected as a part of the Earnest business. As Earnest will no longer originate In-School private loans the loan origination expenses ($28m) and provision for loan losses ($13m) related to In-School private loan originations have been removed to reflect this change in operations.  Total consolidated Navient provision for loan losses for SLR and In-School private loans is forecasted to be $97m for 2025. The Financial Snapshot includes only the  $26m of provision for loan losses related to SLR loan originations. The Financial Snapshot excludes $13m related to In-School private loan originations as well as $58m related to increased losses on the previously originated portfolio (which was primarily the result of elevated delinquency balances and changes in our forecasted macroeconomic outlook that was recognized at September 30, 2025).  Interest expense is reduced by $49m related to assuming a hypothetical higher advance rate on prior securitizations. This higher advance rate on securitizations eliminated $1bn of unsecured debt funding the portfolios. Equity reflected on the Financial Snapshot is based on actual equity in securitization trusts and contractual equity in warehouse facility borrowings.  Expenses for Earnest includes $25m of shared services expenses (corporate and certain IT expenses) related to Earnest that we present in our “Other” segment today.  Two dierent reclassifications were made:  $12m of loan origination cost amortization expense was reclassified from Net Interest Income to sales and marketing expense.  $45m of Interest Income on the loan portfolios was reclassified to Servicing Revenue.
