Exhibit 99.1


Report of Independent Accountants on Applying
Agreed-Upon Procedures

American Credit Acceptance, LLC
961 E. Main Street
Spartanburg, South Carolina 29302

We (“us” or “PwC”) have performed the procedures enumerated below, which were agreed to by American Credit Acceptance, LLC (the “Company,” as the engaging party) and Citigroup Global Markets Inc., who are collectively referred to herein as the “Specified Parties”, solely to assist you in connection with the accuracy of certain attributes of a sample of collateral assets which may be included in the issuance of asset-backed notes by American Credit Acceptance Receivables Trust 2026-2 (the “Transaction”). The Company (the “Responsible Party”) is responsible for the accuracy of the attributes of the collateral assets which may be included in the Transaction.

In an agreed-upon procedures engagement, we perform specific procedures that the Specified Parties have agreed to and acknowledged to be appropriate for the intended purpose of the engagement and we report on findings based on the procedures performed. The procedures performed may not address all the items of interest to a user of this report and may not meet the needs of all users of this report and, as such, users are responsible for determining whether the procedures performed are appropriate for their purposes. The Specified Parties have agreed to and acknowledged that the procedures performed are appropriate for their purposes. This report may not be suitable for any other purpose.

Procedures and Findings

In connection with the Transaction, the Specified Parties agreed on a sample size of 125 automobile loan receivables (each, a “Sample Loan”), which the Specified Parties instructed us to select randomly from the population of loans in the Loan Data Tape (as defined below) where the “booking date” as shown in the Loan Data Tape was within 12 months of the Cut-off Date (as defined below).

This agreed-upon procedures engagement was not conducted for the purpose of satisfying any criteria for due diligence published by a nationally recognized statistical rating organization.

In addition, PwC should not be regarded as having in any way warranted or given any assurance as to the following items:


the completeness, accuracy, appropriateness, quality or integrity of any of the information provided by the Responsible Party, or any other party for purposes of PwC performing the procedures agreed to by the Specified Parties. The procedures performed would not necessarily reveal any material misstatement of the amounts, balances, ratios, percentages or other relationships of the information included in the data provided to us;

the conformity of the origination of the assets to stated underwriting or credit extension guidelines, standards, criteria or other requirements;


the existence of the assets or collateral securing such assets;


the rights of any party including the Specified Parties, the Responsible Party, or the Transaction have to the assets or collateral securing such assets or any obligations on those assets or collateral securing such assets;


the value of collateral securing such assets; and


the compliance of the originator of the assets with federal, state, and local laws and regulations.

We have not performed any procedures with respect to the fair value of the securities being offered in the Transaction and PwC expresses no opinion on the current fair value of these securities. PwC should not be regarded as having performed any procedures other than those detailed in this report.

With respect to any terms or requirements of the offering memorandum or other Transaction documents that do not appear in this report, we performed no procedures and, accordingly, the procedures we performed would not ensure that any requirements are satisfied. Further, we have performed only the following agreed-upon procedures and therefore make no representations regarding the adequacy of disclosures or whether any material facts have been omitted from the offering memorandum or other Transaction documents.

It should be understood that we make no representations as to:


the interpretation of Transaction documents (including, but not limited to, indenture agreements or offering documents) included in connection with our procedures;


your compliance with Rule 15Ga-2 of the Securities Exchange Act of 1934;


the reasonableness of any of the assumptions provided by the Responsible Party; and


the adequacy of the sample size, as provided by the Specified Parties, nor do we draw any conclusions about the entire pool of loan receivables based on the sample size and results of the procedures performed.

These procedures should not be taken to supplant any additional inquiries or procedures that the Specified Parties would undertake in consideration of the Transaction.

The procedures performed and results thereof are as follows. The following definitions have been adopted in presenting our procedures and findings:


The phrase “compare” refers to the comparison of one or more data elements to underlying documentation.


The phrase “Cut-off Date” refers to February 26, 2026.


The phrase “Sample Loans” refers to a sample of 125 automobile loan receivables which have been randomly selected by PwC from the Loan Data Tape and where the “booking date” was within 12 months of the Cut-off Date.


The phrase “STE Loans” refers to Sample Loans with the attribute “STE” in the “lob” field of the Loan Data Tape.

Procedures Performed

In the course of this engagement, in connection with the Data, Information, and Documents, we performed the following agreed-upon procedures on the Sample Loans and reported any findings therefrom. For the purposes of the procedures below, dollar amounts and percentages that differ only as a result of rounding have been deemed to be in agreement.

A.
For each Sample Loan, we compared the following attributes as shown on the Loan Data Tape to the respective data listed in the “Source” column noted in the table below. For purposes of this procedure, we used subsequent sources listed only if the first source used did not agree.

B.
For each Sample Loan, we observed the Contract and Title Documents, noting the absence of the Contract or Title Documents as an exception.


C.
For each Sample Loan, we observed a Truth-In-Lending disclosure statement on the Contract, noting the absence of a Truth-In-Lending disclosure as an exception.


D.
If a Title Document is found in the Contract File, using the Security Interest Confirmation we observed that such document lists the name of the Company (or an Originating Partner, as represented to us by the Company) as the security interest holder, noting the absence of the Company’s name as the security interest holder as an exception.


E.
For each Sample Loan, we observed a Credit Application, noting the absence of a Credit Application as an exception.

As instructed by the Company, for Sample Loans where Credit Application did not note the VIN, we confirmed the Credit Application was for the respective Sample Loan by matching the borrower name and date of birth as noted on the Credit Application with i) Servicing Data for STE Loans and ii) Origination Screenshots for all other Sample Loans.


F.
For each Sample Loan with an original amount financed (as set forth on the Contract) greater than or equal to $5,000.00, we observed an Insurance Document. As instructed by the Company, if the Insurance Document was not provided, we confirmed the presence of “Insurance you must have on the vehicle” section in the Contract. We observed this language in the absence of an Insurance Document for 22 loans, noting an exception if no Insurance Document was observed or there was no “Insurance you must have on the vehicle” section observed in the contract.
