Item 1.

Distribution and Pool Performance Information.

On June 25, 2026, Navient Student Loan Trust 2015-2 (the “Trust”) made its regular monthly distribution of funds to holders of its Student Loan-Backed Notes. Navient Solutions, LLC (formerly, Navient Solutions, Inc.), as the administrator, distributed the Monthly Distribution Report for the Trust for the period identified on the cover of this Form 10-D to the Indenture Trustee, on behalf of the Trust’s noteholders of record. This Monthly Distribution Report is attached to this Report as Exhibit 99.1. This report as well as other information about the Trust is also available on the Administrator’s website at http://www.navient.com/about/investors/debtasset/navientsltrusts/. There is no activity to report under Rule 15Ga-1(a) under the Securities Exchange Act of 1934 with respect to the Trust for the distribution period referred to in the second sentence of this paragraph.

PART II — OTHER INFORMATION

Item 2.

Legal Proceedings.

Navient Corporation (“Navient”) has been named as defendant in a number of putative class action and other cases alleging violations of various state and federal consumer protection laws including the Telephone Consumer Protection Act, the Consumer Financial Protection Act of 2010 (CFPA), the Fair Credit Reporting Act (FCRA), the Fair Debt Collection Practices Act (FDCPA), in adversarial proceedings under the United States Bankruptcy Code, and various state consumer protection laws. At this point in time, Navient is unable to anticipate the timing of a resolution or the impact that these legal proceedings may have on its consolidated financial position, liquidity, results of operation or cash flows. As a result, it is not possible at this time to estimate a range of potential exposure, if any, for amounts that may be payable in connection with these matters and loss contingency accruals have not been established. It is possible that an adverse ruling or rulings may have a material adverse impact on Navient, Navient Solutions and/or their affiliates or on the financial ability of the depositor, the servicer or a seller to fulfill an obligation to purchase or repurchase trust student loans in connection with a breach of representation, warranty or covenant.
