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

Lunai Bioworks Inc. (the “Company”) is unable, without unreasonable effort or expense, to file its Annual Report on Form 10-K for the fiscal year ended June 30, 2026 (the “Form 10-K”) within the prescribed time period. The Company anticipates that it will file the Form 10-K on or before the fifteenth calendar day following the prescribed due date, as permitted by Rule 12b-25(b).

PART IV — OTHER INFORMATION

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

(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.

The Company anticipates reporting a net loss for the fiscal year ended June 30, 2026 of approximately $3.2 million, compared to a net loss of approximately $178.0 million for the fiscal year ended June 30, 2025. The anticipated decrease in net loss is principally attributable to the absence in fiscal 2026 of the approximately $170.4 million goodwill impairment charge recorded in fiscal 2025, the approximately $10.4 million decrease in general and administrative expenses following the Company’s restructuring, the approximately $12.0 million gain recognized upon the deconsolidation of GEDi Cube B.V. following its bankruptcy, partially offset by the approximately $7.4 million loss on extinguishment of debt recognized in connection with the Company’s fiscal 2026 debt restructuring and debt exchange transactions, the approximately $0.832 million impairment of long-lived assets in connection with changes to operating leases and a less favorable year-over-year change of approximately $11.1 million in the fair value of contingent consideration.

The foregoing amounts are preliminary and unaudited, are based on information available to management as of the date of this notification, and remain subject to the completion of the Company’s financial closing procedures and the audit by its independent registered public accounting firm The Company is not presently able to provide reasonable quantitative estimates on the individual components of its results of operations, and actual results may differ materially from these preliminary estimates.
