PART III — NARRATIVE

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.

DNA X, Inc. (the “Company”) is unable to file, without unreasonable effort or expense, its Quarterly Report on Form 10-Q for the three months ended March 31, 2026 (the “Form 10-Q”) within the prescribed time period. This delay resulted primarily from the disposition of the Company’s legacy mobile phone and hotspot business (the “Legacy Business”), the closing of which occurred during the first quarter of 2026. In accordance with Accounting Standards Codification 205-20, Discontinued Operations, the Company is required to present the results of the Legacy Business as a discontinued operation in its condensed consolidated financial statements for the three months ended March 31, 2026. The accounting treatment requires, among other things, the separation of the Legacy Business’s results from continuing operations for the current period, the retrospective recasting of all prior period comparative financial statements to present the Legacy Business as a discontinued operation, the determination of the gain or loss on disposition, and income taxes between continuing and discontinued operations. The complexity of this discontinued operations accounting, combined with the need to ensure the accuracy and completeness of the retrospective recasting of prior periods, has required additional time to complete the Company’s financial close process for the quarter ended March 31, 2026. The Company has been working diligently to complete the discontinued operations presentation and expects to file the Form 10-Q on or before the fifth calendar day following the prescribed due date.

PART IV — OTHER INFORMATION

(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 that its results of operations for the three months ended March 31, 2026 will differ significantly from the corresponding three month period ended March 31, 2025 for the following reasons:

As discussed above in Part III, the Company is in the process of completing the preparation of its consolidated financial statements for the three month period ended March 31, 2026. The Company expects to report net loss from continuing operations of approximately $3.6 million for the three months ended March 31, 2026, compared to net loss of $0.7 million for the three months ended March 31, 2025. The increase in net loss was attributable to increased general and administrative expense resulting from severance and bonus payments triggered by the completion of the sale of the Legacy Business and higher professional fees due to the complexity of such sale of the Legacy Business in 2026.
