Exhibit 99.1

ANNEX A

THE TRUST STUDENT LOAN POOL

The trust student loans owned by the trust were originally selected from a portfolio of consolidation student loans owned by SLM ECFC and VG Funding by employing several criteria, including requirements that each trust student loan as of the original cutoff date (and with respect to each additional trust student loan as of its related subsequent cutoff date):

•

was a consolidation loan guaranteed as to principal and interest by a guaranty agency under a guarantee agreement and the guaranty agency was, in turn, reinsured by the Department of Education in accordance with the FFELP;

•

contained terms in accordance with those required by the FFELP, the guarantee agreements and other applicable requirements;

•

was fully disbursed;

•

was not more than 210 days past due;

•

did not have a borrower who was noted in the related records of the servicer as being currently involved in a bankruptcy proceeding; and

•

had special allowance payments, if any, based on the three-month commercial paper rate or the 91-day Treasury bill rate.

No trust student loan as of the applicable cutoff date was subject to any prior obligation to sell that loan to a third party.

Unless otherwise specified, all information with respect to the trust student loans is presented as of August 31, 2025, which is the statistical disclosure date.

The following tables provide a description of specified characteristics of the trust student loans as of the statistical disclosure date. The aggregate outstanding principal balance of the loans in each of the following tables includes the principal balance due from borrowers, plus accrued interest of $1,988,111 to be capitalized as of the statistical disclosure date. Percentages and dollar amounts in any table may not total 100% or whole dollars due to rounding. The following tables also contain information concerning the total number of loans and total number of borrowers in the portfolio of trust student loans. For ease of administration, the servicer separates a consolidation loan on its system into two separate loan segments representing subsidized and unsubsidized segments of the same loan. The following tables reflect those loan segments within the number of loans. In addition, 8 borrowers have more than one trust student loan.

The distribution by weighted average interest rate applicable to the trust student loans on any date following the statistical disclosure date may vary significantly from that in the following tables as a result of variations in the effective rates of interest applicable to the trust student loans and in rates of principal reduction. Moreover, the information below about the weighted average remaining term to maturity of the trust student loans as of the statistical disclosure date may vary significantly from the actual term to maturity of any of the trust student loans as a result of prepayments or the granting of deferment and forbearance periods.

The following tables also contain information concerning the total number of loans and the total number of borrowers in the portfolio of trust student loans.

Percentages and dollar amounts in any table may not total 100% of the trust student loan balance, as applicable, due to rounding.

Weighted Average Annual Interest Rate		4.81	%

(1)	Trust student loans with special allowance payments indexed to one-month LIBOR will be indexed to 30-day Average SOFR from and after July 1, 2023.

We determined the weighted average remaining term to maturity shown in the table from the statistical disclosure date to the stated maturity date of the applicable trust student loan without giving effect to any deferment or forbearance periods that may be granted in the future. See Appendix A to the preliminary remarketing memorandum.

The weighted average annual borrower interest rate shown in the table is exclusive of special allowance payments. The weighted average spread for special allowance payments to the 91-day Treasury bill rate was 3.12% as of the statistical disclosure date.

The weighted average spread for special allowance payments to the one-month LIBOR rate was 2.64% as of the statistical disclosure date. See “Special Allowance Payments” in Appendix A to the preliminary remarketing memorandum.

The category “Other” in the table above represents the Health Education Assistance Loan Program (which we refer to as “HEAL” and the loans originated under such program as “HEAL Loans”) portion of any consolidation loans made under the FFELP which consolidated one or more Stafford Loans, SLS Loans and/or PLUS Loans with one or more student loans originated under the HEAL Program. These consolidation loans are guaranteed as to principal and interest by a guaranty agency and reinsured by the Department of Education. The HEAL portion of any consolidation loan is not eligible to receive special allowance payments or interest subsidy payments. The interest rate on the HEAL Loan segment of any such consolidation loan is variable and is reset each July 1, based upon the average bond-equivalent rate for 91-day Treasury bills auctioned during the three months ending June 30, plus 3.0%. In addition, the applicable interest rate on the HEAL Loan segment of any such consolidation loan is not subject to any cap on the interest rate that may apply to the principal of the HEAL Loan segment.

For these purposes, the 91-day Treasury bill rate is the weighted average per annum discount rate, expressed on a bond equivalent basis and applied on a daily basis, for direct obligations of the United States with a maturity of thirteen weeks, as reported by the U.S. Department of the Treasury.

We determined the interest rates shown in the table above using the interest rates applicable to the trust student loans as of the statistical disclosure date. Because trust student loans with different interest rates are likely to be repaid at different rates, this information is not likely to remain applicable to the trust student loans after the statistical disclosure date.

Current borrower payment status refers to the status of the borrower of each trust student loan as of the statistical disclosure date. The borrower:

•

may have temporarily ceased repaying the loan through a deferment or a forbearance period (this category includes the Coronavirus Disaster Forbearance Program); or

•

may be currently required to repay the loan – repayment.

See Appendix A to the preliminary remarketing memorandum and “The Student Loan Pools – SLM Corporation’s Student Loan Financing Business” in the prospectus.

The weighted average number of months in repayment for all trust student loans currently in repayment is approximately 159.2 calculated as the term to maturity at the commencement of repayment less the number of months remaining to scheduled maturity as of the statistical disclosure date.

Deferment		17.7		-		201.3

Repayment		-		-		166.8

We have determined the scheduled weighted average remaining months in status shown in the previous table without giving effect to any deferment or forbearance periods that may be granted in the future. Of the $10,917,407 aggregate outstanding principal balance of the trust student loans in deferment as of the statistical disclosure date, $7,277,331 or approximately 66.7% of such loans are to borrowers who had not graduated as of that date. We expect that a significant portion of these loans could qualify for additional deferments or forbearances at the end of their current deferment periods as the related borrowers continue their education beyond their current degree programs. As a result, the overall duration of any applicable deferment and forbearance periods as well as the likelihood of future deferment and forbearance periods within this pool of trust student loans is likely to be higher than in other pools of student loans without similar numbers of in-school consolidation loans. See Appendix A to the preliminary remarketing memorandum and “The Student Loan Pools – SLM Corporation’s Student Loan Financing Business” in the prospectus.

We have based the geographic distribution shown in the table on the billing addresses of the borrowers of the trust student loans shown on the servicer’s records as of the statistical disclosure date.

A-8

Each of the trust student loans provides or will provide for the amortization of its outstanding principal balance over a series of regular payments. Except as described below, each regular payment consists of an installment of interest which is calculated on the basis of the outstanding principal balance of the trust student loan. The amount received is applied first to interest accrued to the date of payment and the balance of the payment, if any, is applied to reduce the unpaid principal balance. Accordingly, if a borrower pays a regular installment before its scheduled due date, the portion of the payment allocable to interest for the period since the preceding payment was made will be less than it would have been had the payment been made as scheduled, and the portion of the payment applied to reduce the unpaid principal balance will be correspondingly greater. Conversely, if a borrower pays a monthly installment after its scheduled due date, the portion of the payment allocable to interest for the period since the preceding payment was made will be greater than it would have been had the payment been made as scheduled, and the portion of the payment applied to reduce the unpaid principal balance will be correspondingly less.

In either case, subject to any applicable deferment periods or forbearance periods, and except as provided below, the borrower pays a regular installment until the final scheduled payment date, at which time the amount of the final installment is increased or decreased as necessary to repay the then outstanding principal balance of that trust student loan.

The servicer makes available to borrowers of student loans it holds (including the trust student loans) payment terms that may result in the lengthening of the remaining term of the student loans. For example, not all of the loans sold to the trust provide for level payments throughout the repayment term of the loans. Some student loans provide for interest only payments to be made for a designated portion of the term of the loans, with amortization of the principal of the loans occurring only when payments increase in the latter stage of the term of the loans. Other loans provide for a graduated phase in of the amortization of principal with a greater portion of principal amortization being required in the latter stages than would be the case if amortization were on a level payment basis. The servicer also offers an income-sensitive repayment plan, under which repayments are based on the borrower’s income. Under that plan, ultimate repayment may be delayed up to five years. Borrowers under trust student loans will continue to be eligible for the graduated payment and income-sensitive repayment plans. These programs are applicable to the trust student loans and may be offered by the servicer to related borrowers at its discretion.

The following table provides certain information about trust student loans subject to the repayment terms described in the preceding paragraphs.

(1)	Includes, among others, graduated repayment and interest-only period loans.

(2)	Includes income sensitive and income based repayment.

With respect to interest-only loans, as of the statistical disclosure date, there are 119 loans with an aggregate outstanding principal balance of $6,815,310 currently in an interest-only period. These interest-only loans represent approximately 1.5% of the aggregate outstanding principal balance of the trust student loans. Interest-only periods range up to 48 months in overall length.

The servicer may in the future offer repayment terms similar to those described above to borrowers of trust student loans who are not entitled to these repayment terms as of the statistical disclosure date. If repayment terms are offered to and accepted by those borrowers, the weighted average life of the securities could be lengthened.
