Zapata Quantum, Inc.

Item 3. Defaults Upon Senior Securities.

During the fourth quarter of 2024, an event of default occurred under the Company’s Senior Secured Promissory Notes issued pursuant to the Senior Secured Note Purchase Agreement dated December 15, 2023. Under the terms of these notes, the Company’s Current Report on Form 8-K filed on October 11, 2024, in which the Company disclosed that, at that time, it was unable to, and unlikely to become able to, satisfy all of its financial obligations, constituted an event of default. As a result, all amounts outstanding under the Senior Secured Promissory Notes became immediately due and payable.

As of November 30, 2025, the Company has repaid approximately $1 million of principal, together with accrued interest, and has cured the event of default with respect to the remaining principal balance and accrued interest under the Senior Secured Promissory Notes. No Senior Secured Promissory Notes, or other Senior Securities, remain in default as of the filing date of this report.
