Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 7 footnotes

Footnote F1

Performance restricted stock units ("Performance RSUs") convert into common stock on a one-for-one basis.

Footnote F2

Represents the shares that were withheld by the Issuer to cover withholding taxes upon the vesting of 275,032 Performance RSUs and 46,857 restricted stock units.

Footnote F3

Includes 208,393 previously granted time-based RSUs which have not yet vested.

Footnote F4

Previously purchased by the West Community Property Trust dated May 18, 2023, for which the reporting person is trustee.

Footnote F5

On October 1, 2024, the reporting person was granted Performance RSUs, which vest based upon the achievement of certain performance criteria over the three year period following the date of grant (each such year, a "Performance Period"), with up to 33% of such units vesting (on each anniversary of the date of grant) with respect to each applicable Performance Period. Additionally, a portion of the Performance RSUs may vest during a later Performance Period if the cumulative % increase in value of Mitek common stock measured over the current and all previous Performance Periods exceeds the cumulative % increase in value of the Russell 2000 Index (the "Catch-up Performance Criteria").

Footnote F6

The annual performance criteria for each annual Performance Period is for the % increase in value of Mitek's common stock to meet or exceed the % increase in value of the Russell 2000 Index over the applicable annual Performance Period, based on a hypothetical investment in both Mitek's common stock and the Russell 2000 Index with a purchase price equal to the average closing price of each for the 20-trading days immediately preceding the start of the applicable Performance Period. At the end of the applicable Performance Period, the value of the hypothetical investments is determined by assuming the sale of each based on the average closing price of each from the immediately preceding 20-trading days. The % change is determined by comparing the increase in value to the starting investment.

Footnote F7

For the October 1, 2026 vesting, 133% of the target shares vested based on the achievement of the performance criteria described above for the annual Performance Period ending on that date. An additional 13.7% of the target shares that did not vest with the annual Performance Period ending on October 1, 2025 vested on October 1, 2026, based on the achievement of the Catch-up Performance Criteria from grant date through October 1, 2026.
