Explanatory Note

This Current Report on Form 8-K/A (this “Amendment”)

amends and restates the Current Report on Form 8-K filed by Deep Isolation Nuclear, Inc. (the “Company”) with the U.S. Securities

and Exchange Commission on August 31, 2026 (the “Original Report”). The purpose of this Amendment is to correct certain numerical

errors in Item 5.02 of the Original Report relating to the one-time bonus payments to Chris Parker, Chief Commercial Officer, and Jesse

Sloane, Executive Vice President, Engineering. No other changes have been made to the Original Report. Except as specifically amended

hereby, the Original Report remains in full force and effect as originally filed.

Item 5.02 Departure of Directors or Certain

Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

CEO Compensation

As previously reported in the proxy statement

on Schedule 14A filed by Deep Isolation Nuclear, Inc., a Delaware corporation (the “Company”) on April 29, 2026, effective

as of February 1, 2026 the annual base salary of Rodney Baltzer, President and Chief Executive Officer of the Company, was $425,000 and

his target bonus was 75% of his annual base salary, which was approved by the Compensation Committee (the “Committee”) of

the Board of Directors (the “Board”) of the Company on February 23, 2026. At that time, the Committee approved and, upon recommendation

of the Committee, on February 24, 2026, the Board approved an increase in the annual base salary of Mr. Baltzer from $340,000 to $425,000

and his target bonus from 35% to 75% of his annual base salary.

Officers’ Compensation Changes

On August 25, 2026, the Committee and, upon its

recommendation, the Board approved changes to the compensation of certain of the Company’s officers, effective as of July 1, 2026.

Under the approved changes, the annual base salaries of Chris Parker, Chief Commercial Officer, and Jesse Sloane, Executive Vice President,

Engineering, were increased from £180,500, and $259,500 to £215,000 and $315,000, respectively. In addition, the target bonus

for each of Mr. Parker and Mr. Sloane was increased from 20% to 35% of their respective annual base salaries.

Because the compensation changes for Mr. Parker

and Mr. Sloane were approved by the Board on August 25, 2026 with a retroactive effective date of July 1, 2026, the Board also approved

one-time bonus payments to such officers to account for the difference in compensation for the July and August pay periods, as follows:

Mr. Parker received a one-time payment of £5,750; and Mr. Sloane received a one-time payment of $9,143.

SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934,

as amended, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
