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.

Mobix Labs, Inc. (the "Company") has determined that it is unable, without unreasonable effort or expense, to file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2026 (the "Form 10-Q") by the prescribed due date because the Company needs additional time, in part due to turnover within the Company's accounting department, to finalize review of the Company's financial statements and evaluation of disclosure controls and procedures to be included in its Form 10-Q. The Company expects to file the quarterly report within the extension period.

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's results of operations for the quarter ended March 31, 2026 will reflect changes from the quarter ended March 31, 2025. While the Company is still reviewing and finalizing its financial results, it is able to provide certain preliminary results. The Company expects to report the following for the quarter ended March 31, 2026: (i) loss from operations of approximately $6.1 million, an improvement compared to loss from operations of $7.8 million for the quarter ended March 31, 2025; (ii) net revenues of approximately $970 thousand, as compared to net revenues of $2.5 million for the quarter ended March 31, 2025, primarily reflecting supply chain disruptions and related production delays at a significant customer, which the Company anticipates will be substantially resolved during the current quarter; and (iii) net loss of approximately $5.9 million, as compared to net loss of $2.3 million for the quarter ended March 31, 2025, with the year-over-year change driven primarily by the non-recurrence of non-cash gains recognized in the prior-year quarter from changes in the fair value of the Company's warrant and earnout liabilities, together with higher interest expense, rather than changes in underlying operating performance rather than operating performance. The Company anticipates executing certain arrangements to provide additional liquidity prior to the filing of the Form 10-Q, however the Company's financial statements for the quarter ended March 31, 2026 will continue to reflect there is substantial doubt about the Company's ability to continue as a going concern for the next twelve months.

These are preliminary results based on current expectations and are still under review and subject to change. Actual results may differ.

Forward-Looking Statements

This Form 12b-25 includes information that constitutes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the Registrant's current beliefs, assumptions and expectations regarding future events, which in turn are based on information currently available to the Registrant. Such forward-looking statements include statements regarding the anticipated timing of completion of the Company's financial results for the quarter ended March 31, 2026, and the Company's expectations with respect to its results of operations for the quarter ended March 31, 2026. By their nature, forward-looking statements address matters that are subject to risks and uncertainties. A variety of factors could cause actual events and results to differ materially from those expressed in or contemplated by the forward-looking statements. These factors include, without limitation, the risk that additional or different information may become known prior to the expected filing of the periodic report described herein. Other risks affecting the Company are discussed in the Company's filings with the SEC, including its most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q. The Company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by applicable laws.
