Issuing Entity

The transferor has prepared a preliminary prospectus dated July 6, 2026 that describes the Class A(2026-1) notes to be issued by the issuing entity. You should review the preliminary prospectus in its entirety before deciding to purchase any of the Class A(2026-1) notes.

Ratings

The issuing entity will issue the Class A(2026-1) notes only if they are rated by the following nationally recognized statistical rating organizations as follows:

A rating addresses the likelihood of the payment of interest on a note when due and the ultimate payment of principal of that note by its legal maturity date. A rating does not address the likelihood of payment of principal of a note on its expected principal payment date. In addition, a rating does not address the possibility of an early payment or acceleration of a note, which could be caused by an early redemption event or an event of default. A rating is not a recommendation to buy, sell or hold notes and may be subject to revision or withdrawal at any time by the assigning rating agency. A rating is based on each rating agency's independent evaluation of the receivables and the availability of any credit enhancement for the notes. A rating, or a change or withdrawal of a rating, by one rating agency will not necessarily correspond to a rating, or a change or withdrawal of a rating, from any other rating agency. If any of the ratings of these Class A(2026-1) notes changes, Class A(2026-1) noteholders will not be so notified by Capital One, National Association, Capital One Funding, LLC or Capital One Multi-asset Execution Trust.
