Item 8.01 Other Events.

On March 31, 2026, SC II Acquisition Corp., a

Cayman Islands exempted company (the “Company”), entered into a non-binding letter of intent (the “LOI”) with

a payments technology company (the “Target”), which outlines the general terms and conditions of a potential business combination

(the “Proposed Transaction”) pursuant to which the Company would acquire 100% of the outstanding equity and equity equivalents

of the Target. The Company’s sponsor, SC Capital II Sponsor LLC, is controlled and majority owned by Nukkleus Defense Technologies

Inc., a wholly-owned subsidiary of T3 Defense Inc.

The LOI is a preliminary, non-binding expression

of mutual interest and does not constitute a binding commitment, obligation or agreement of the Company or the Target to consummate the

Proposed Transaction or any other transaction. Except for certain limited binding provisions, including, among other things, exclusivity,

confidentiality, the waiver of claims against the Company’s trust account, and governing law, neither the Company nor the Target

has any legal obligation to the other party with respect to the Proposed Transaction by virtue of the LOI.

Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking

statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform

Act of 1995. Forward-looking statements may be identified by the use of words such as “may,” “should,” “could,”

“would,” “expects,” “intends,” “plans,” “anticipates,” “believes,”

“estimates,” “predicts,” “potential,” “project,” “proposed,” “continue,”

“will” or the negative of these terms or other comparable terminology. These forward-looking statements include, but are not

limited to, statements regarding the Proposed Transaction and the ability of the parties to consummate the Proposed Transaction. These

forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown

risks, uncertainties, assumptions and other important factors, many of which are outside the Company’s control, that could cause

actual results or outcomes to differ materially from those discussed in the forward-looking statements. Important factors that could cause

actual results to differ materially include, among others: (i) the inability of the Company and the Target to negotiate and execute definitive

agreements with respect to the Proposed Transaction; (ii) the inability of the Company and the Target to satisfy the conditions to the

closing of the Proposed Transaction; (iii) the occurrence of any event, change or other circumstances that could give rise to the termination

of the LOI or the definitive agreements for the Proposed Transaction; (iv) the inability to obtain regulatory approvals; (v) the risk

that the Proposed Transaction disrupts current plans and operations of the Company or the Target; (vi) costs related to the Proposed Transaction;

(vii) the level of redemptions by the Company’s public stockholders; and (viii) those factors discussed in the Company’s prospectus

dated November 25, 2025, and other documents filed from time to time with the U.S. Securities and Exchange Commission. The Company cautions

that the foregoing list of factors is not exclusive. The Company cautions readers not to place undue reliance upon any forward-looking

statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly

any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions

or circumstances on which any such statement is based.
