8548 Rozita Lee Avenue, Suite 305

(Address of Principal Executive Office (Street and Number))

Las Vegas, NV 89113

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

	(a)	The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;

☒	(b)	The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and

	(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Alt5 Sigma Corporation (the “Company”) is unable to file, without unreasonable effort and expense, its Annual Report on Form 10-K for the fiscal year ended December 27, 2025 (the “Form 10-K”). The Company requires additional time to finalize its annual financial statements (due to finalization of certain accounting treatment relative to the Company’s acquisition completed during the fiscal year) and to complete the audit process thereof (also due to the previously announced change in the Company’s PCAOB-registered public accounting firm) for the relevant part of the Form 10-K. As disclosed, the Company’s prior Audit Report on Form 10-K of the Company did not contain an adverse opinion or disclaimer of opinion by the Company’s previous accounting firms on its financial statements for the fiscal years ended December 28, 2024 and December 30, 2023 and was not qualified or modified as to uncertainty, audit scope, or accounting principles. During the Company’s two most recent fiscal years ended December 28, 2024 and December 30, 2023, and for the subsequent interim period through December 25, 2025 (the date of the change in the Company’s accounting firm), the Company had no “disagreements” (as described in Item 304 (a)(1)(iv) of Regulation S-K) with the previous accounting firm on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of the previous accounting firms, would have caused them to make reference in connection with the included opinions to the subject matter of the disagreements. The Company currently expects to file the Form 10-K on or before April 13, 2026, the prescribed due date under the 15-calendar-day-extension period provided under Rule 12b-25.

PART IV — OTHER INFORMATION

(1)	Name and telephone number of person to contact in regard to this notification

Steven Plumb		713		780-0806
(Name)		(Area Code)		(Telephone Number)

(2)	Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s). ☒ Yes ☐ No

(3)	Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? ☒ Yes ☐ No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

As discussed above in Part III, the Company is in the process of completing the preparation of its financial statements and the audit process thereof for its fiscal year ended December 27, 2025. The Company expects to report a net loss in the range of $340 million - $345 million for the fiscal year ended December 27, 2025.
