**Series 2026-1 Asset Backed Notes**

The depositor has prepared a preliminary prospectus dated May 15, 2026, which describes the Series 2026-1 Class A notes (the "offered notes") to be issued by the issuing entity. You should review the prospectus in its entirety before deciding to purchase any of the offered notes.

**Ratings**

The issuing entity will issue the offered notes only if they are rated by the following nationally recognized statistical rating organizations as follows:

---

| | | |
|:---|:---|:---|
|  | **Moody's Investors Service, Inc.**<br> **("Moody's")** | **Fitch Ratings Inc.**<br> **("Fitch")** |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Class A notes | Aaa (sf)<sup>\*</sup> | AAAsf\* |

---

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 final 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 a pay-out 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. Each rating is based on the corresponding rating agency's independent evaluation of the receivables and the availability of any credit enhancement for the notes. Ratings will be monitored by the applicable rating agencies while the notes are outstanding and, in certain instances described in the preliminary prospectus, First National Bank of Omaha or its affiliates may from time to time request the applicable rating agencies to confirm their ratings with respect to 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 a withdrawal of a rating, from any other rating agency. If any of the ratings of the offered notes changes, holders of the offered notes will not be so notified by First National Bank of Omaha, First National Funding LLC or First National Master Note Trust.
