Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 5 footnotes

Footnote F1

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

Footnote F2

Represents the disposition of shares that were withheld by the Issuer to pay withholding taxes upon the vesting of 12,958 Performance RSUs and 14,546 restricted stock units.

Footnote F3

On January 2, 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. For the January 2, 2026 vesting, approximately 67% of the target shares vested based on the achievement of the performance criteria described below.

Footnote F4

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 F5

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.
