**Supplement dated May 1, 2026**

**to the following prospectus(es):**

Nationwide Advisory Retirement Income Annuity<sup>SM</sup> prospectus dated May 1, 2026

**This supplement updates certain information contained in your prospectus. Please read and retain this** <br> **supplement for future reference.**<br>

This Rate Sheet Supplement ("Supplement") should be read and retained with the prospectus for Nationwide Advisory Retirement Income Annuity<sup>SM</sup>. This Supplement replaces and supersedes any previous Rate Sheet Supplement and must be used in conjunction with the prospectus. If you need another copy of the prospectus, please contact the Service Center at 1-866-667-0561.

Nationwide is issuing this Supplement to provide the current:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lifetime Withdrawal Percentages, Roll-up Interest Rate, and Roll-up Crediting Period for the Nationwide Lifetime Income Rider Plus Core Advisory and Joint Option for the Nationwide Lifetime Income Rider Plus Core Advisory; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lifetime Withdrawal Percentages, Roll-up Interest Rate, and Roll-up Crediting Period for the Nationwide Lifetime Income Rider Plus Accelerated Advisory and Joint Option for the Nationwide Lifetime Income Rider Plus Accelerated Advisory; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lifetime Withdrawal Percentages for the Pro 4SM option and Joint Option for the Pro 4 option.

**The Roll-up Interest Rate, Roll-up Crediting Period, and Lifetime Withdrawal Percentages provided below apply to applications signed on or after May 1, 2026.**

**It is important that you have the most current Rate Sheet Supplement as of the date you sign the application. This Supplement has no specified end date and can be superseded at any time. If Nationwide supersedes this Supplement with a new Rate Sheet Supplement, the new Rate Sheet Supplement will be filed a minimum of 10 business days prior to its effective date.**

**<u>For the Nationwide Lifetime Income Rider Plus Core Advisory (and the Joint Option) and the Nationwide Lifetime Income Rider Plus Accelerated Advisory (and the Joint Option) only</u>**: If your application is signed on or after the date shown above, and a new Rate Sheet Supplement is filed with an effective date on or before the date the contract is issued, then based on the optional benefit elected the following will apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the Roll-up Interest Rate increased, then the higher Roll-up Interest Rate in effect on the date the contract is issued will be applied to the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If the applicable Lifetime Withdrawal Percentages increased, then the higher Lifetime Withdrawal Percentages in effect on the date the contract is issued will be applied to the contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• However, if the Roll-up Interest Rate decreased, or any applicable Lifetime Withdrawal Percentages decreased, then the Roll-up Interest Rate and Lifetime Withdrawal Percentages in effect on the date the application is signed will be applied to the contract.

Note: The rate comparison process described above *does not include* consideration of any change in the Roll-up Crediting Period. Therefore, for example, if both the Roll-up Interest Rate increased and the applicable Lifetime Withdrawal Percentages increased, but the Roll-up Crediting Period decreased, then the higher Roll-up Interest Rate, higher Lifetime Withdrawal Percentages, and shorter Roll-up Crediting Period in effect on the date the contract is issued will be applied to the contract.

If your application was signed before the date shown above, please refer to your contract for the Roll-up Interest Rate, Roll-up Crediting Period, and Lifetime Withdrawal Percentages that are applicable to your contract, or contact the Service Center.

All Rate Sheet Supplements are available by contacting the Service Center, and also are available at https://nationwide.onlineprospectus.net/nw/naria/index.php or onthe EDGAR system at www.sec.gov (file number: 333-227783).
