RULES 12b-25(b) AND (c)
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-CEN 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.
State below in reasonable detail the reasons 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.
Mitek Systems, Inc. (the “Company”) is unable to file its Quarterly Report on Form 10-Q for its fiscal quarter ended December 31, 2023 (the “Q1 Form 10-Q”) within the prescribed time period without unreasonable effort or expense for the reason described below.

As disclosed in the Company’s Current Report on Form 8-K filed on May 27, 2022, the Company received formal notice of the resignation of its previous independent registered public accounting firm, and as disclosed in the Form 8-K filed on July 18, 2022, engaged a new independent registered public accounting firm to act as the Company’s registered public accounting firm. As a result of the Company’s transition to a new independent registered public accounting firm and the delays related to the filing of the Company’s Quarterly Report on Form 10-Q for the period ended June 30, 2022, filed on October 28, 2022 and the Amendment No. 1 to the Company’s Quarterly Report on Form 10-Q for the period ended March 31, 2022, filed on October 28, 2022, the Company needed additional time to complete its procedures related to its Annual Report on Form 10-K for its fiscal year ended September 30, 2022, filed on July 31, 2023. The Company was then delayed in filing its Quarterly Reports on Form 10-Q for the periods ended December 31, 2022, March 31, 2023 and June 30, 2023, all of which were filed as of October 26, 2023. As a result of the delays in these filings, the Company was late in starting its year-end audit for its fiscal year ended September 30, 2023 and has not yet filed the Form 10-K for such period (the “Form 10-K”). The Company cannot file the Q1 Form 10-Q until the Form 10-K is filed. The Company expects to file the Q1 Form 10-Q as soon as practicable following the filing of the Form 10-K.
