Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company as of December 31, 2023 have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all information and footnote disclosures required by accounting principles generally accepted in the U.S. (“GAAP”). The Company believes the footnotes and other disclosures made in the financial statements are adequate for a fair presentation of the results of the interim periods presented. The financial statements include all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary to make the information presented not misleading. You should read these financial statements and the accompanying notes in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, filed with the U.S. Securities and Exchange Commission (“SEC”) on March 19, 2024. Results for the three months ended December 31, 2023, are not necessarily indicative of results for any other interim period or for a full fiscal year. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, deferred taxes, and related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual results could differ materially from those estimates. These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards, fair value of assets and liabilities acquired, impairment of goodwill, useful lives of intangible assets, fair value of debt derivatives, standalone selling price related to revenue recognition, contingent consideration, and income taxes. Net Income (Loss) Per Share For the three months ended December 31, 2023 and 2022, the following potentially dilutive common shares were excluded from the calculation of net income (loss) per share, as they would have been antidilutive ( amounts in thousands ): Three Months Ended December 31, 2023 2022 Stock options 594 502 RSUs 1,749 860 ESPP common stock equivalents 49 130 Performance options 476 741 Performance RSUs 1,312 296 Convertible senior notes 7,448 7,448 Warrants 7,448 7,448 Total potentially dilutive common shares outstanding 19,076 17,425 The calculation of basic and diluted net income (loss) per share is as follows ( amounts in thousands, except per share data) : Three Months Ended December 31, 2023 2022 Net income (loss) $ (5,793) $ 4,726 Weighted-average shares outstanding—basic 46,294 44,930 Common stock equivalents — 704 Weighted-average shares outstanding—diluted 46,294 45,634 Net income (loss) per share: Basic $ (0.13) $ 0.11 Diluted $ (0.13) $ 0.10 Other Borrowings The Company has certain loan agreements with Spanish government agencies which were assumed when the Company acquired ICAR Vision Systems, S.L. ("ICAR") in 2017. These agreements have repayment periods of five Recently Adopted Accounting Pronouncements The Company did not adopt any new accounting pronouncements in the quarter ended December 31, 2023. Change in Significant Accounting Policy The Company’s significant accounting policies are disclosed in the Company’s audited condensed consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2023, filed with the SEC on March 19, 2024. There have been no changes to these accounting policies through December 31, 2023. Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures amending existing income tax disclosure guidance, primarily requiring more detailed disclosure for income taxes paid and the effective tax rate reconciliation. The ASU is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted and can be applied on either a prospective or retroactive basis. The Company is currently evaluating the ASU to determine its impact on its income tax disclosures. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04) and also issued subsequent amendments to the initial guidance (collectively, Topic 848). Topic 848 provides optional guidance for contract modifications and certain hedging relationships associated with the transition from reference rates that are expected to be discontinued. The Company will adopt Topic 848 when the relevant contracts are modified upon transition to alternative reference rates. The Company does not expect the adoption of Topic 848 will have a material impact on the condensed consolidated financial statements. No other new accounting pronouncement issued or effective during the three months ended December 31, 2023 had, or are expected to have, a material impact on the Company’s condensed consolidated financial statements.

REVENUE RECOGNITION

REVENUE RECOGNITION	3 Months Ended
	Dec. 31, 2023
Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	2. REVENUE RECOGNITION Nature of Goods and Services The following is a description of principal activities from which the Company generates its revenue. Contracts with customers are evaluated on a contract-by-contract basis as contracts may include multiple types of goods and services as described below. Software and Hardware Software and hardware revenue is generated from on premise software license sales, as well as sales of hardware scanner boxes and on premise appliance products. Software is typically sold as a time-based license with a term of one Services and Other Services and other revenue is generated from the sale of software as a service (“SaaS”) products and services, maintenance associated with the sale of on premise software licenses and consulting and professional services. The Company’s SaaS offerings give customers the option to be charged upon their incurred usage in arrears (“Pay as You Go”), or commit to a minimum spend over their contracted period, with the ability to purchase unlimited additional transactions above the minimum during the contract term. Revenue related to Pay as You Go contracts are recognized based on the customer’s actual usage, in the period of usage. For contracts which include a minimum commitment, the Company is standing ready to provide as many transactions as desired by the customer throughout the contract term, and revenue is recognized on a ratable basis over the contract period including an estimate of usage above the minimum commitment. Usage above minimum commitment is estimated by looking at historical usage, expected volume, and other factors to project out for the remainder of the contract term. The estimated usage-based revenues are constrained to the amount the Company expects to be entitled to receive in exchange for providing access to its platform. If professional services are deemed to be distinct, revenue is recognized as services are performed. The Company does not view the signing of the contract or the provision of initial setup services as discrete earnings events that are distinct. Significant Judgments in Application of the Guidance The Company uses the following methods, inputs, and assumptions in determining amounts of revenue to recognize: Identification of Performance Obligations For contracts that contain multiple performance obligations, which include combinations of software licenses, maintenance, and services, the Company accounts for individual goods or services as a separate performance obligation if they are distinct. The good or service is distinct if the good or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. Determination of Transaction Price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The Company includes any fixed charges within its contracts as part of the total transaction price. To the extent that variable consideration is not constrained, the Company includes an estimate of the variable amount, as appropriate, within the total transaction price and updates its assumptions over the duration of the contract. As a practical expedient, the Company does not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less. Assessment of Estimates of Variable Consideration Many of the Company’s contracts with customers contain some component of variable consideration; however, variable consideration will only be included in the transaction price to the extent it is probable that a significant reversal of revenues recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company may constrain the estimated transaction price in the event of a high degree of uncertainty as to the final consideration amount owed because of an extended length of time over which the fees may be adjusted or due to uncertainty surrounding collectability. The Company estimates variable consideration in its contracts primarily using the expected value method as the Company believes this method represents the most appropriate estimate for this consideration, based on historical usage trends, the individual contract considerations, and its best judgment at the time. Allocation of Transaction Price The transaction price, including any discounts, is allocated between separate goods and services in a contract that contains multiple performance obligations based on their relative standalone selling prices. The standalone selling prices are based on the prices at which the Company separately sells each good or service. For items that are not sold separately, the Company estimates the standalone selling prices using available information such as market conditions and internally approved pricing guidelines. In certain situations, primarily transactional SaaS revenue described above, the Company allocates variable consideration to a series of distinct goods or services within a contract. The Company allocates variable payments to one or more, but not all, of the distinct goods or services or to a series of distinct goods or services in a contract when (i) the variable payment relates specifically to the Company’s efforts to transfer the distinct good or service and (ii) the variable payment is for an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to its customer. Disaggregation of Revenue The following table presents the Company's revenue disaggregated by major product category ( amounts in thousands ): Three Months Ended December 31, 2023 2022 Major product category Deposits software and hardware $ 14,048 $ 24,453 Deposits services and other 7,029 5,828 Deposits revenue 21,077 30,281 Identity verification software and hardware 1,932 1,923 Identity verification services and other 13,908 13,499 Identity verification revenue 15,840 15,422 Total revenue $ 36,917 $ 45,703 Contract Balances The following table provides information about contract assets and contract liabilities from contracts with customers ( amounts in thousands ): December 31, 2023 September 30, 2023 December 31, 2022 September 30, 2022 Contract assets, current $ 17,305 $ 18,355 $ 6,223 $ 7,037 Contract assets, non-current 7,216 5,579 10,741 4,218 Contract liabilities (deferred revenue), current 18,330 17,360 12,647 21,350 Contract liabilities (deferred revenue), non-current 1,051 957 1,236 1,775 Contract assets, reported within a separate line in current assets and the other non-current assets line in the condensed consolidated balance sheets, primarily result from when the right to consideration is conditional upon factors other than the passage of time. Contract liabilities primarily relate to advance consideration received from customers (deferred revenue), for which transfer of control occurs, and therefore revenue is recognized as services are provided. Contract balances are reported in a net contract asset or liability position on a contract-by-contract basis at the end of each reporting period. The Company recognized $9.1 million and $6.6 million of revenue during the three months ended December 31, 2023, and 2022, respectively, which was included in the contract liability balance at the beginning of each such period. Unbilled receivables are included within accounts receivable, net on the condensed consolidated balance sheets and were $0.6 million and $0.9 million as of December 31, 2023 and September 30, 2023, respectively. Contract assets, current and contract liabilities (deferred revenue), current, for the three months ended December 31, 2022 have been revised, as previously disclosed in Note 15 in the Annual Report on Form 10-K for the year ended September 30, 2023, filed with the SEC on March 19, 2024. These immaterial revisions are made for consistency. Contract Costs Contract costs included in other current and non-current assets on the condensed consolidated balance sheets totaled $2.4 million and $2.6 million as of December 31, 2023 and September 30, 2023, respectively. Contract origination costs consist primarily of: (1) sales commissions and incentive payments made to the Company’s direct and indirect sales personnel, and (2) the associated payroll taxes and fringe benefit costs associated with the payments to the Company’s employees. Contract origination costs are amortized based on the transfer of goods or services to which the asset relates, including consideration of the expected customer benefit period. Contract fulfillment costs related to goods or services transferred under a specific anticipated contract have historically been immaterial. These costs are included in selling and marketing expenses in the condensed consolidated statement of operations and comprehensive income and totaled $0.4 million during each of the three months ended December 31, 2023 and 2022. There were no impairment losses recognized during both the three months ended December 31, 2023 and 2022 related to capitalized contract costs.

Corporate debt securities are valued using quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. As of December 31, 2023, no acquisition-related contingent consideration is recorded in the condensed consolidated balance sheets. The Company recorded the acquisition date fair value based on the likelihood of contingent earnout payments related to the Company’s acquisition of ID R&D Inc., as part of the consideration transferred. The earnout payments consist of cash payments and issuances of Common Stock and are subsequently remeasured to fair value each reporting date. Additionally, for contingent consideration to be settled in a variable number of shares of Common Stock, the Company used the most recent Mitek share price as reported by the Nasdaq Capital Market to determine the fair value of the shares expected to be issued. The Company previously classified the contingent consideration as Level 3, due to the lack of relevant observable inputs and market activity. The second earnout period ended on May 28, 2023 and the Company recorded the value based on the calculated final payout and reclassified the contingent consideration as Level 2 during the third quarter of fiscal 2023. The contingent consideration was settled during the three months ended December 31, 2023.

As of December 31, 2023, the Company had $33.7 million of unrecognized compensation expense expected to be recognized over a weighted-average period of approximately 2.7 years. 2020 Incentive Plan In January 2020, the Company’s Board of Directors (the “Board”) adopted the Mitek Systems, Inc. 2020 Incentive Plan (the “2020 Plan”) upon the recommendation of the Compensation Committee of the Board. On March 4, 2020, the Company’s stockholders approved the 2020 Plan. The total number of shares of Common Stock reserved for issuance under the 2020 Plan is 4,500,000 shares plus such number of shares, not to exceed 107,903, as remained available for issuance under the 2002 Stock Option Plan, 2006 Stock Option Plan, 2010 Stock Option Plan, and 2012 Incentive Plan (collectively, the “Prior Plans”) as of January 17, 2020, plus any shares underlying awards under the Prior Plans that are terminated, forfeited, cancelled, expire unexercised or are settled in cash after January 17, 2020.

On October 2, 2023, the Company held an annual meeting of its stockholders (the “Annual Meeting”). At the Annual Meeting, the Company’s stockholders approved an amendment and restatement of the 2020 Plan to increase the number of shares authorized for issuance thereunder by 5,108,000 shares (the 2020 Plan as so amended and restated, the “A&R 2020 Plan”). The A&R 2020 Plan had been previously approved, subject to stockholder approval, by the Company’s Board of Directors (the “Board”), upon recommendation of the Compensation Committee of the Board, on August 9, 2023. A summary of the A&R 2020 Plan was included in the Company’s definitive proxy statement for the Annual Meeting filed with the U.S. Securities and Exchange Commission on August 22, 2023, as supplemented and amended on September 19, 2023 (the “Proxy Statement”). Employee Stock Purchase Plan In January 2018, the Board adopted the ESPP. On March 7, 2018, the Company’s stockholders approved the ESPP. The total number of shares of Common Stock reserved for issuance thereunder is 1,000,000 shares. As of December 31, 2023, (i) 729,124 shares have been issued to participants pursuant to the ESPP and (ii) 270,876 shares of Common Stock were reserved for future purchases under the ESPP. The Company commenced the initial offering period on April 2, 2018. The ESPP enables eligible employees to purchase shares of Common Stock at a discount from the market price through payroll deductions, subject to certain limitations. Eligible employees may elect to participate in the ESPP only during an open enrollment period. The offering period immediately follows the open enrollment window, at which time ESPP contributions are withheld from the participant's regular paycheck. The ESPP provides for a 15% discount on the market value of the stock at the lower of the grant date price (first day of the offering period) and the purchase date price (last day of the offering period). The Company recognized $0.1 million in stock-based compensation expense related to the ESPP in each of the three months ended December 31, 2023 and 2022. Director Restricted Stock Unit Plan In January 2011, the Board adopted the Mitek Systems, Inc. Director Restricted Stock Unit Plan, as amended and restated (the “Director Plan”).

Income Tax Disclosure [Abstract]
INCOME TAXES	6. INCOME TAXES The Company’s tax provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, management updates the estimate of the annual effective tax rate, and any changes are recorded in a cumulative adjustment in that quarter. The quarterly tax provision and quarterly estimate of the annual effective tax rate are subject to significant volatility due to several factors, including management’s ability to accurately predict the portion of income (loss) before income taxes in multiple jurisdictions, the tax effects of our stock-based compensation awards, and the effects of acquisitions and the integration of those acquisitions. For the three months ended December 31, 2023 and 2022, the Company recorded an income tax benefit of $1.7 million and an income tax provision of $1.8 million, respectively, which yielded an effective tax rate of 23% and 28%, respectively. The difference between the U.S. federal statutory tax rate and the Company’s effective tax rate for the three months ended December 31, 2023 and 2022 was primarily due to a mix of worldwide income, the impact of non-deductible executive compensation as well as the impact of state taxes, and federal and state research and development credits on the tax provision.

CONVERTIBLE SENIOR NOTES	7. CONVERTIBLE SENIOR NOTES The carrying values of the 0.75% convertible notes due 2026 issued by the Company in an initial aggregate principal amount of $155.3 million (the “2026 Notes”) are as follows ( amounts in thousands ): 2026 Notes: December 31, 2023 September 30, 2023 Principal amount $ 155,250 $ 155,250 Less: unamortized discount and issuance costs, net of amortization (17,764) (19,734) Carrying amount $ 137,486 $ 135,516 In February 2021, the Company issued $155.3 million aggregate principal amount of the 2026 Notes (including the Additional Notes, as defined below). The 2026 Notes are senior unsecured obligations of the Company. The 2026 Notes were issued pursuant to an Indenture, dated February 5, 2021 (the “Indenture”), between the Company and UMB Bank, National Association, as trustee. The Indenture includes customary covenants and sets forth certain events of default after which the 2026 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the 2026 Notes become automatically due and payable. The Company granted the initial purchasers of the 2026 Notes (collectively, the “Initial Purchasers”) a 13-day option to purchase up to an additional $20.25 million aggregate principal amount of the 2026 Notes (the “Additional Notes”), which was exercised in full. The 2026 Notes were purchased in a transaction that was completed on February 5, 2021. As of January 13, 2024 (“Date of Noncompliance”), the Company was not in compliance with certain of the covenants in the Indenture as a result of the Company not timely filing its Form 10-K for the fiscal year ended September 30, 2023 (“Form 10-K”) with the SEC. As a result of not being in compliance, the 2026 Notes began to accrue additional special interest of 0.25% of the outstanding principal of the 2026 Notes for the 90 days after the Date of Noncompliance and 0.50% of the outstanding principal of the 2026 Notes for the 91st through 180th day after the Date of Noncompliance. The Company subsequently did not timely file its Form 10-Q for the quarter ended December 31, 2023 with the SEC. The Company filed its Form 10-K with the SEC on March 19, 2024. As of the filing of this Quarterly Report on Form 10-Q for the period ended December 31, 2023, the Company is in compliance with the covenants in the Indenture as all of its required annual and quarterly reports to date have been filed with the SEC. The 2026 Notes will mature on February 1, 2026, unless earlier redeemed, repurchased or converted. The 2026 Notes bear interest from February 5, 2021 at a rate of 0.750% per year payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2021. The 2026 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding August 1, 2025, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021, if the last reported sale price per share of Common Stock exceeds 130% of the conversion price for each of at least 20 trading days during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during five consecutive business days immediately after any five consecutive trading day period (such five consecutive trading day period, the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of the Common Stock on such trading day and the conversion rate on such trading day; (3) upon the occurrence of certain corporate events or distributions on the Common Stock. On or after August 1, 2025, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2026 Notes, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. Upon conversion, the Company may satisfy its conversion obligation by paying and/or delivering, as the case may be, cash and, if applicable at the Company’s election, shares of the Common Stock, based on the applicable conversion rate(s); provided that the Company will be required to settle conversions solely in cash unless and until the Company (i) receives stockholder approval to increase the number of authorized shares of the Common Stock and (ii) reserves such amount of shares of the Common Stock for future issuance as required pursuant to the Indenture that governs the 2026 Notes. The conversion rate for the 2026 Notes will initially be 47.9731 shares of the Common Stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of approximately $20.85 per share of the Common Stock. The initial conversion price of the 2026 Notes represents a premium of approximately 37.5% to the $15.16 per share last reported sale price of the Common Stock on February 2, 2021. The conversion rate is subject to adjustment under certain circumstances in accordance with the terms of the Indenture. The net proceeds from this offering were approximately $149.7 million, after deducting the Initial Purchasers’ discounts and commissions and the Company’s estimated offering expenses related to the offering. The Company used approximately $9.3 million of the net proceeds from the offering to pay the cost of the Notes Hedge, after such cost is partially offset by the proceeds from the Warrant Transactions described below. The Initial Purchasers exercised their option to purchase Additional Notes in full and the Company used a portion of the net proceeds from the sale of such Additional Notes to enter into additional Notes Hedges, after such cost is partially offset by the proceeds from the additional Warrant Transactions, with the Option Counterparties (as defined below). The Company intends to use the remainder of the net proceeds from the offering for general corporate purposes, which may include working capital, capital expenditures, and potential acquisitions and strategic transactions. As of December 31, 2023, the number of authorized and unissued shares of Common Stock that are not reserved for other purposes is sufficient to settle the 2026 Notes into equity. Accordingly, the Company may settle conversions of notes through payment or delivery, as the case may be, of cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the Company’s election. In accounting for the issuance of the 2026 Notes, the conversion option of the 2026 Notes was deemed an embedded derivative requiring bifurcation from the 2026 Notes (“host contract”) and separate accounting as an embedded derivative liability, as a result of the Company not having the necessary number of authorized but unissued shares of its Common Stock available to settle the conversion option of the 2026 Notes in shares. The proceeds from the 2026 Notes were first allocated to the embedded derivative liability and the remaining proceeds were then allocated to the host contract. On February 5, 2021, the fair value of the embedded derivative liability representing the conversion option was $33.2 million and the remaining $116.5 million was allocated to the host contract. The difference between the principal amount of the 2026 Notes and the fair value of the host contract (the “debt discount”) is amortized to interest expense using the effective interest method over the term of the 2026 Notes. In the second quarter of fiscal 2022, the stockholders of the Company approved an increase to the number of authorized shares of Common Stock, to an amount sufficient to settle the conversion of the 2026 Notes. As a result of the increase to the number of authorized shares of Common Stock, the Company reclassified the embedded conversion derivative to additional paid-in capital. As of December 31, 2023, the embedded conversion derivative is included in additional paid-in capital in the condensed consolidated balance sheets and will not be remeasured provided the requirements to qualify for the scope exception in Accounting Standards Codification (“ASC”) 815-10-15-74(a) continue to be met. Debt issuance costs for the issuance of the 2026 Notes were approximately $5.5 million, consisting of initial purchasers' discount and other issuance costs. In accounting for the transaction costs, the Company allocated the total amount incurred to the 2026 Notes. Transaction costs were recorded as debt issuance cost (presented as contra debt in the condensed consolidated balance sheet) and are being amortized using the effective interest method to interest expense over the term of the 2026 Notes. The following table presents the total amount of interest cost recognized relating to the 2026 Notes ( amounts in thousands ): Three Months Ended December 31, 2023 2022 Contractual interest expense $ 293 $ 293 Amortization of debt discount and issuance costs 1,970 1,844 Total interest expense recognized $ 2,263 $ 2,137 The derived effective interest rate on the 2026 Notes host contract was determined to be 6.71%, which remains unchanged from the date of issuance. The remaining unamortized debt discount was $17.8 million as of December 31, 2023, and will be amortized over approximately 2.1 years. Convertible Senior Notes Hedge and Warrants In connection with the pricing of the 2026 Notes, the Company entered into the Notes Hedge with Bank of America, N.A., Jefferies International Limited and Goldman Sachs & Co. LLC (the “Option Counterparties”). The Notes Hedge provided the Company with the option to acquire, on a net settlement basis, approximately 7.4 million shares of Common Stock at a strike price of $20.85, which is equal to the number of shares of Common Stock that notionally underlie and correspond to the conversion price of the 2026 Notes. The Company also entered into Warrant Transactions with the Option Counterparties relating to the same number of shares of the Common Stock, subject to customary anti-dilution adjustments. The strike price of the Warrant Transactions is $26.53 per share, which represents a 75.0% premium to the last reported sale price of the Common Stock on the Nasdaq Capital Market on February 2, 2021, and is subject to certain adjustments under the terms of the Warrant Transactions. The Company was initially required to settle the Notes Hedge in cash, as they did not qualify for the scope exception for contracts involving an issuer’s own equity in ASC 815 and were accounted for as a derivative asset. Upon initial purchase, the Notes Hedge was recorded in convertible senior notes hedge sufficient to settle the conversion of the 2026 Notes. As a result of the increase to the number of authorized shares of Common Stock, the Company reclassified the Notes Hedge to additional paid-in capital. As of December 31, 2023, the Notes Hedge is included in additional paid-in capital in the condensed consolidated balance sheet and will not be remeasured provided the requirements to qualify for the scope exception in ASC 815-10-15-74(a) continue to be met and the Company had not purchased any shares under the Notes Hedge. As a result of the Warrant Transactions, the Company is required to recognize incremental dilution of earnings per share to the extent the average share price is over $26.53 for any fiscal quarter. During the three months ended December 31, 2023, there was no dilution of earnings per share. The Warrant Transactions expire over a period of 80 trading days commencing on May 1, 2026 and may be settled in net shares of Common Stock or net cash at the Company’s election. Upon initial sale, the Warrant Transactions were recorded as an increase in additional paid-in capital within stockholders’ equity of $23.9 million. As of December 31, 2023, the Warrant Transactions had not been exercised and remained outstanding.

COMMITMENTS AND CONTINGENCIES	8. COMMITMENTS AND CONTINGENCIES Legal Proceedings Claim Against ICAR On June 11, 2018, a claim was filed before Court of First Instance 5 (Juzgado de Primera Instancia) of Barcelona, Spain, the first instance court in the Spanish civil procedure system, against ICAR. The claim, also directed towards Mr. Xavier Codó Grasa, the former controlling shareholder of ICAR and its current General Manager at the time the claim was filed, was brought by the Spanish company Global Equity & Corporate Consulting, S.L. for an alleged breach by ICAR of a services agreement entered into in the context of the sale of all of the shares in ICAR to Mitek Holding B.V., a wholly owned subsidiary of the Company. ICAR responded to the claim on September 7, 2018. After several postponements as a consequence of the COVID-19 pandemic, on March 3, 2022 the trial was held. On June 7, 2022, the Court of First Instance 5 of Barcelona issued a judgment which fully upheld the claim and declared that Mr. Xavier Codó Grasa and ICAR had to pay the amount and damages claimed by Global Equity & Corporate Consulting, S.L. equal to €0.8 million (or $0.8 million as of December 31, 2023), plus the interest accrued and the legal fees. ICAR and Mr Xavier Codó Grasa submitted an appeal against this judgment on July 13, 2022. Global Equity & Corporate Consulting, S.L. filed an opposition to that appeal on September 2, 2022. The next procedural step will be the voting and issuing of the ruling on the appeal. Global Equity & Corporate Consulting, S.L. requested the provisional enforcement of the judgment, asking ICAR and Mr. Xavier Codó Grasa to deposit the damages awarded plus 30% to cover the possible interests that may continue to accrue during the appeal (€1.1 million in total) with the Court. According to the terms of the sale and purchase agreement concerning the acquisition of the shares in ICAR, Mitek Holding B.V. is to be indemnified in respect of any damages suffered by ICAR and/or Mitek Holding B.V. in respect of this claim. As a consequence, the escrow (€0.9 million) was released pursuant to the provisional enforcement of the judgment, and Mr. Xavier Codó Grasa deposited the remaining €0.2 million. Global Equity & Corporate Consulting, S.L. also requested that ICAR and Mr. Xavier Codó Grasa bear the costs of the provisional enforcement. This amounted to €16,475 for the accrued interests and €10,995 as legal costs. ICAR and Mr. Xavier Codó Grasa have complied with this request, having such amounts charged to the damages deposited with the Court. Third Party Claims Against the Company’s Customers The Company receives indemnification demands from end-user customers who received third party patentee offers to license patents and allegations of patent infringement. Some of the offers and allegations have resulted in ongoing litigation. The Company is not a party to any such litigation. License offers to and infringement allegations against the Company’s end-customers were made by Lighthouse Consulting Group, LLC; Lupercal, LLC; Pebble Tide, LLC; Dominion Harbor Group, LLC; and IP Edge, LLC, which appear to be non-practicing entities (“NPEs”)—often called “patent trolls”—and not the Company’s competitors. These NPEs may seek to extract settlements from our end-customers, resulting in new or renewed indemnification demands to the Company. At this time, the Company does not believe it is obligated to indemnify any customers or end-customers resulting from license offers or patent infringement allegations by the companies listed above. However, the Company could incur substantial costs if it is determined that it is required to indemnify any customers or end-customers in connection with these offers or allegations. Given the potential for impact to other customers and the industry, the Company is actively monitoring the offers, allegations and any resulting litigation. On July 7, 2018, United Services Automobile Association (“USAA”) filed a lawsuit against Wells Fargo Bank, N.A. (“Wells Fargo”) in the Eastern District of Texas alleging that Wells Fargo’s remote deposit capture systems (which in part utilize technology provided by the Company to Wells Fargo through a partner) infringe four USAA owned patents related to mobile deposits (the “First Wells Lawsuit”). On August 17, 2018, USAA filed a second lawsuit (the “Second Wells Lawsuit” and together with the First Wells Lawsuit, the “Wells Lawsuits”) against Wells Fargo in the Eastern District of Texas asserting that an additional five patents owned by USAA were infringed by Wells Fargo’s remote deposit capture system. In neither lawsuit was the Company named in the Complaint as an infringer nor at any time did USAA allege specifically that the Company’s products by themselves infringed any of the asserted patents. Subsequently, on November 6, 2019, a jury in the First Wells Lawsuit found that Wells Fargo willfully infringed at least one of the Subject Patents (as defined below) and awarded USAA $200 million in damages. In the Second Wells Lawsuit, USAA dropped two of the patents from the litigation, and the judge in the case found that one of the remaining three patents was invalid. On January 10, 2020, a jury in the Second Wells Lawsuit found that Wells Fargo willfully infringed at least one of the patents at issue in that case and awarded USAA $102 million in damages. No Mitek product was accused of infringing either of the two patents in question in the Second Wells Lawsuit as the litigation involved broad banking processes and not the Company’s specific mobile deposit features. USAA and Wells Fargo subsequently reached a settlement, and on April 1, 2021 the Court granted the parties’ joint motion and stipulation of dismissal of the Wells Lawsuits with prejudice. Wells Fargo filed petitions for Inter Partes Review (“IPR”) with the Patent Trial and Appeal Board (“PTAB”) challenging the validity of the four patents in the First Wells Lawsuit. Three of those four petitions were instituted, while one (relating to U.S. Patent No. 9,818,090 (“the ‘090 Patent”)) was denied institution. On November 24, 2020, and January 26, 2021, the PTAB issued final written decisions determining that Wells Fargo had not demonstrated by a preponderance of the evidence that any claims of the U.S. Patent Nos. 8,977,571 (“the ‘571 Patent”), 8,699,779 (“the ‘779 Patent”), or 9,336,517 (“the ‘517 Patent”) were unpatentable. On September 30, 2020, USAA filed suit against PNC Bank (the “First PNC Lawsuit”) in the Eastern District of Texas alleging infringement of U.S. Patent Nos. 10,482,432 (“the ‘432 Patent”) and 10,621,559. These two patents are continuations of an asserted patent in the Second Wells Lawsuit and relate to similar subject matter. On October 19, 2020, PNC Bank’s integration partner, NCR Corporation, sent an indemnification demand to the Company requesting indemnification from all claims related to the First PNC Lawsuit. The complaint against PNC Bank does not claim that any Company product infringes any of the asserted patents. At this time, the Company does not believe it is obligated to indemnify NCR Corporation or end-users of NCR Corporation resulting from the patent infringement allegations by USAA. On December 4, 2020, USAA filed an amended complaint against PNC Bank also asserting two patents at issue in the First Wells Lawsuit—the ’779 Patent and the ’571 Patent. On February 2, 2021, NCR Corporation sent a second indemnification demand to the Company requesting indemnification of the claims described in the amended complaint. On March 31, 2021, USAA filed another suit against PNC Bank in the Eastern District of Texas alleging infringement of two patents from the Second Wells Lawsuit, U.S. Patent Nos. 10,013,605 (“the ‘605 Patent”) and 10,013,681 (“the ‘681 Patent”) (the “Second PNC Lawsuit”). On July 7, 2021, USAA filed a third lawsuit against PNC Bank (the “Third PNC Lawsuit” and together with the First PNC Lawsuit and the Second PNC Lawsuit, the “PNC Lawsuits”) asserting infringement of U.S. Patents 10,769,598; 10,402,638; and 9,224,136. A jury trial was held in May 2022 on the consolidated First PNC Lawsuit and Second PNC Lawsuit. The jury found that PNC willfully infringed at least one patent claim and awarded USAA $218 million in damages. The Court denied PNC Bank’s equitable defenses and entered a Final Judgment in the consolidated First PNC Lawsuit and Second PNC Lawsuit on August 19, 2022. A jury trial was held in September 2022 on the Third PNC Lawsuit. The jury found that PNC infringed at least one patent claim and awarded USAA $4.3 million in damages. The Court entered a Final Judgment in the Third PNC Lawsuit on February 16, 2023. While neither the Wells Lawsuits nor the PNC Lawsuits name the Company as a defendant, given (among other factors) the Company’s prior history of litigation with USAA and the continued use of the Company’s products by its customers, on November 1, 2019, the Company filed a complaint in the U.S. District Court for the Northern District of California seeking declaratory judgment that its products do not infringe the ’779 Patent, the ’571 Patent, the ’517 Patent, and the ’090 Patent (collectively, the “Subject Patents”). On January 15, 2020, USAA filed motions requesting the dismissal of the declaratory judgement of the Subject Patents and transfer of the case to the Eastern District of Texas, both of which the Company opposed. On April 21, 2020, the Court in the Northern District of California transferred the Company’s declaratory judgement action to the Eastern District of Texas and did not rule on USAA’s motion to dismiss. On April 28, 2021, the Court in the Eastern District of Texas granted USAA’s motion to dismiss the Company’s declaratory judgment action on jurisdictional grounds. The Court’s ruling did not address the merits of the Company’s claim of non-infringement. The Company appealed the ruling on the motion to dismiss and the decision to transfer the declaratory judgment action from California to Texas to the U.S. Court of Appeals for the Federal Circuit. The Federal Circuit heard oral argument on the Company’s appeal on April 4, 2022 and on May 20 2022, issued an opinion vacating and remanding the district court’s order granting USAA’s motion to dismiss. On August 1, 2022, the parties submitted additional briefing to the district court in light of Federal Circuit’s opinion. The court held another hearing on USAA’s motion to dismiss the Company’s declaratory judgment action on jurisdictional grounds, and once again granted USAA’s motion to dismiss on February 23, 2023. The Company timely filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit. The appeal is fully briefed, and the Company is awaiting oral argument. The Company continues to believe that its products do not infringe the Subject Patents and will vigorously defend the right of its end-users to use its technology. In April, May, and June 2020, the Company filed petitions for IPR with the PTAB of the U.S. Patent & Trademark Office challenging the validity of the Subject Patents. On November 6 and 17, 2020, the PTAB decided to exercise its discretion and deny institution of the four petitions due to the alleged relationship between the Company and Wells Fargo, who previously filed petitions for IPR on the Subject Patents. The PTAB did not address the merits of the Company’s petitions or the prior art cited in those petitions. The Company continues to believe that the prior art cited in the petitions renders all the claims of the Subject Patents invalid. On each of December 6, 2020, December 17, 2020, and February 23, 2021, the Company filed requests for rehearing and Precedential Opinion Panel (“POP”) review of the four denied IPR petitions. The Patent Office denied the requests for rehearing and for POP review. In September 2020, the Company filed an additional two petitions for IPR with the U.S. Patent & Trademark Office challenging the validity of the ‘681 Patent and the ‘605 Patent—two of the patents at issue in the Second Wells Lawsuit. In March 2021, the PTAB decided not to institute the two petitions. On July 7, July 14, and July 21 2021, PNC Bank filed six additional petitions for IPR with the U.S. Patent & Trademark Office challenging the validity of the ’779 Patent, the ’571 Patent, the ‘559 Patent, and the ‘432 Patent. On August 27, 2021, PNC filed two additional petitions for IPR challenging the validity of the ‘681 Patent and the ‘605 Patent. In October and November of 2021, PNC Bank filed four more petitions for IPR challenging the validity of the ‘638 Patent, the ‘136 Patent, and the ‘598 Patent. The Patent Office denied institution with respect to the petitions challenging the ‘432 Patent, the ‘605 Patent, the ‘681 Patent, and the ‘638 Patent, but instituted inter partes review on the petitions relating to the ‘779 Patent, the ‘571 Patent, the ‘559 Patent, and the ‘598 Patent—finding a reasonable likelihood that at least one challenged patent claim was invalid. The U.S. Patent & Trademark Office issued a final written decision in each of the IPRs challenging the ‘779 Patent, the ‘571 Patent, and the ‘559 Patent and found all challenged claims of each patent unpatentable. USAA filed requests for rehearing and requests for POP review. The requests for POP review and for rehearing were denied in March 2023. On August 16, 2021, USAA filed suit against BBVA USA (“BBVA”) in the Eastern District of Texas alleging infringement of the same patents at issue in the PNC Lawsuits. While the Company’s IPR petitions were mentioned in the complaint, the Company was not named as a defendant or mentioned in connection with any alleged infringement. BBVA then sent the Company an indemnification demand on September 7, 2021. For the same reasons discussed above in connection with PNC Bank and the PNC Lawsuits, the Company does not believe it is obligated to indemnify BBVA. On June 6, 2022, the Court granted the parties’ request to administratively close the case and stay all deadlines in view of the pending appeal in the PNC Lawsuits. On July 29, 2022, USAA filed another patent infringement lawsuit against Truist Bank (“Truist”) in the Eastern District of Texas. The lawsuit alleges infringement of the ’090 Patent, the ’432 Patent, and the U.S. Patent No. 11,182,753 (“the ’753 Patent”). The Company was not named as a defendant or mentioned in connection with any alleged infringement. On October 5, 2022, Truist’s integration partner, NCR Corporation, sent an indemnification demand to the Company requesting indemnification from all claims related to the lawsuit. For the same reasons discussed above in connection with the PNC Lawsuits, the Company does not believe it is obligated to indemnify NCR Corporation or end-users of NCR Corporation resulting from the patent infringement allegations by USAA. On October 7, 2022, Truist filed a motion to transfer venue to the Western District of North Carolina. The motion was denied on April 8, 2023. On December 30, 2022, Truist filed a motion for leave to file counterclaims against USAA alleging patent infringement of U.S. Patent Nos. 7,336,813; 7,519,214; 8,136,721; and 9,760,797, which was granted on April 8, 2023. On March 13, 2023, USAA moved for leave to file a First Amended Complaint, adding an additional allegation of patent infringement of U.S. Patent No. 11,544,944 (“the ’944 Patent”). On April 4, 2023, Truist sent another indemnification demand to the Company requesting indemnification related to the lawsuit. On May 3, 2023, USAA moved for leave to file a Second Amended Complaint, adding an additional allegation of patent infringement of U.S. Patent No. 11,625,770 (“the ’770 Patent”). On May 30, 2023, Truist sent another indemnification demand to the Company requesting indemnification related to the Second Amended Complaint. On October 6, 2023, the parties filed a Notice of Settlement and Joint Motion and Stipulation of Dismissal. All claims and causes of action between the parties were dismissed with prejudice on October 10, 2023 in view of the settlement. In October and November of 2022, Truist filed a petition for IPR with the U.S. Patent & Trademark Office challenging the validity of the ’090 Patent, the ’432 Patent, and the ’753 Patent. The Patent Office instituted the petitions directed to the ’090 and ’753 Patents, but denied institution of the petition directed to the ’432 Patent. In view of the settlement between USAA and Truist, the IPRs were withdrawn. The Company incurred legal fees of $0.6 million and $0.3 million in the three months ended December 31, 2023 and 2022, respectively, related to third party claims against our customers. Such fees are included in general and administrative expenses in the condensed consolidated statement of operations and comprehensive income. Claim Against UrbanFT, Inc. On July 31, 2019, the Company filed a lawsuit against one of its customers, UrbanFT, Inc. (“UrbanFT”) in the United States District Court for the Southern District of California (case No. 19-CV-1432-CAB-DEB). UrbanFT is delinquent in payment and attempted to justify its non-payment by asserting that the Company is or may be infringing on purported UrbanFT patents. The Company filed such lawsuit to collect the delinquent payments and to obtain a declaratory judgment of non-infringement of five purported UrbanFT patents. UrbanFT filed an answer and later asserted infringement of two of the five patents-at-issue in the Company’s lawsuit against UrbanFT. The Company thereafter filed counterclaims seeking a declaration that the two patents now asserted by UrbanFT are invalid in addition to being not infringed. During the course of the litigation, the Company learned that a judgment had been entered against UrbanFT’s affiliates and its predecessor owner in which an Oregon court ordered that the patents in issue revert to a prior owner, Mr. Stevens, because UrbanFT’s affiliates did not pay the purchase price owed to the prior owner. On September 8, 2020, the Company filed a motion for summary judgment on its breach of contract claim. On September 15, 2020, the district court issued an order to show cause regarding jurisdiction over patent issues in light of the Oregon judgment. On December 17, 2020, the district court dismissed Mitek’s claims for declaratory judgment of non-infringement and UrbanFT’s counterclaims for patent infringement and related affirmative defenses based on infringement of the patents for lack of subject matter jurisdiction because UrbanFT does not own the patents. The district court then dismissed the remaining state law claims without prejudice to refiling in state court. On December 18, 2020, the Company filed a new suit against UrbanFT in the Superior Court of the State of California, County of San Diego (case no. 37-2020-00046670-CU-BC-CTL) asserting claims for breach of contract, open book account, and monetary damages. UrbanFT filed an answer and did not assert any cross-claims. The Company filed a motion for summary judgment which was heard on April 15, 2022. The Court granted the Company’s motion and on June 2, 2022, entered a judgment in favor of the Company for $1.7 million in compensatory damages, plus costs, including attorney’s fees. The Court awarded the Company $2,600 in costs plus $0.6 million in attorneys’ fees for a total judgment of $2.3 million. The time for UrbanFT to appeal the $1.7 million in compensatory damage judgment has expired but the time for UrbanFT to appeal the attorneys’ fee and cost award has not. No appeal has been filed. On August 2, 2023, the Company filed a separate lawsuit against Richard Steggall, UFT (North America), LLC fka Urban FT LLC; Urban FT Group, Inc; Urban FT Client Solutions, LLC; UFT Professional Services, LLC; and X-35 Financial Technologies, in the San Diego Superior Court, (case No. 37-2023-00033005-CU-FR-CTL) (“Fraud Conveyance Action”). The Fraud Conveyance Action alleges that the Mr. Steggall orchestrated a scheme to strip UFT (North America), LLC of any assets and effectively transfer the Urban FT business to other entities he owns and controls, all to avoid the Company’s collection efforts. The Fraud Conveyance Action also alleges that Mr. Steggall funnels Urban FT’s revenues through a web of other entities he owns and controls, all to ensure that creditors, including the Company, cannot collect their debts. The parties have started discovery. On February 23, 2024, the Court set the Fraud Conveyance Action for trial on March 14, 2025. Separately, the Company filed two motions to compel discovery set for April 12, 2024. The defendants have filed a motion to quash the Company’s subpoena to Chase Bank and the defendants filed an Order to Show Cause to hold the Company in contempt for violating the parties’ Protective Order. The Company anticipates filing its own motion for sanctions against defendants for their frivolous contempt motion. Claim Against Maplebear, Inc (dba Instacart): On December 13, 2021, Mitek filed a lawsuit against Maplebear Inc., d/b/a Instacart (“Instacart”), in California Superior Court – San Diego County (Case No, 37-2021-00052089-CU-BC-CTL)) (the “Instacart Lawsuit”). Mitek alleged causes of action for breach of contract as well as breach of the implied covenant and requested over $2.0 million in damages. On August 3, 2018 Instacart entered into a Master Services Agreement (the “Master Services Agreement”) with Mitek agreeing to purchase a subscription to Mitek’s Mobile Verify Advanced service. On June 19, 2020, the parties entered into a second Order Form in connection with the Master Services Agreement. The Order Form had a term of June 18, 2020 to December 31, 2023 and called for an annual commitment of $1.2 million. On September 23, 2021, Instacart sent a letter to Mitek purporting to outline breaches under the Master Services Agreement. Mitek responded on November 11, 2021, refuting Instacart’s claims and offering to engage in further discussions. Instacart thereafter sent a Notice of Termination of the Master Services Agreement dated November 24, 2021. The Parties participated in mediation on March 15, 2022. The mediation did not result in the resolution of the case and, following mediation, the Parties stipulated that Instacart’s response to Mitek’s complaint would be due on April 27, 2022. In lieu of filing a response to the complaint, Instacart elected to file a Motion to Transfer Venue to the County of San Francisco, which the Court denied, thereby keeping the case in the County of San Diego. On November 28, 2022, Instacart filed a cross-complaint against Mitek alleging: (1) Fraudulent Inducement; (2) Intentional Misrepresentation; (3) False Advertising; (4) Fraudulent Business Practices; (5) Unlawful Business Practices; (6) Unfair Business Practices; (7) Breach of Contract; and (8) Breach of the Implied Covenant of Good Faith and Fair Dealing. On January 27, 2023, Mitek filed a demurrer to the cross-complaint (the functional equivalent of a motion to dismiss). Both Parties also filed motions to compel further responses to written discovery requests. The Court did not decide the demurrer or the motions to compel before the Parties resolved and dismissed the case. On September 29, 2023, the Parties reached an agreement to resolve the case. The terms of the settlement were completed and, on October 24, 2023, the Company filed a Request for Dismissal, signed by counsel for both parties and asking the clerk of the Court to dismiss the Company’s complaint and causes of action as well as Instacart’s cross-complaint and causes of action. The Court entered the Request for Dismissal on October 24, 2023 and dismissed the Parties’ respective claims with prejudice. Biometric Information Privacy Act Claims On December 16, 2021, the Company was sued in a putative class action in the Circuit Court of Cook County, Illinois alleging that the Company had violated the Illinois Biometric Information Privacy Act (“BIPA”) with respect to identity verification services that the Company provided to its customer HyreCar, Inc. (“HyreCar”) for HyreCar’s customers in Illinois (the “BIPA Lawsuit”). Plaintiff claimed that the Company had not obtained the required consent to collect and use Plaintiff’s biometric information, and that Plaintiff and a class of similarly situated individuals therefore are entitled to statutory damages under BIPA. The Company removed the BIPA Lawsuit to the U.S. District Court for the Northern District of Illinois, and on March 4, 2022 the Company filed a Motion to Compel Arbitration based on HyreCar’s terms and conditions requiring HyreCar customers to arbitrate on an individual (non-class) basis (the “Arbitration Motion”). On May 4, 2022 the trial court denied the Arbitration Motion. On December 21, 2022, the trial court’s ruling was upheld on appeal, and the case subsequently was remanded back to the trial court. On March 10, 2023, Plaintiff filed an Amended Complaint adding a second named plaintiff, who is also a HyreCar end-user, but otherwise not materially changing the allegations. On March 27, 2023, the Company filed a Motion to Dismiss or, in the Alternative, to Strike Class Allegations. On May 11, 2023, and after the Company’s Motion to Dismiss or, in the Alternative, to Strike Class Allegations had been fully briefed, Plaintiffs filed a Motion for Leave to File a Second Amended Complaint seeking to add two new named plaintiffs, who are end-users of the Company’s customers Instacart and Roadie, and to remove one named plaintiff. The Company opposed the Motion for Leave. On September 13, 2023, Plaintiffs filed a Notice of Voluntary Dismissal. On September 14, 2023, the Court dismissed the lawsuit without prejudice, ending the litigation. Other Legal Matters In addition to the foregoing, the Company is subject to various claims and legal proceedings arising in the ordinary course of its business. The Company accrues for such liabilities when it is both (i) probable that a loss has occurred and (ii) the amount of the loss can be reasonably estimated in accordance with ASC 450, Contingencies . While any legal proceeding has an element of uncertainty, the Company believes that the disposition of such matters, in the aggregate, will not have a material effect on the Company’s financial condition or results of operations.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	11. SUBSEQUENT EVENTS On February 13, 2024 (the “Closing Date”), the Company, A2iA Corp., and ID R&D, Inc. (jointly and severally, individually and collectively, “Borrower”) entered into a Loan and Security Agreement (the “Credit Agreement”) with Silicon Valley Bank, a division of First-Citizens Bank & Trust Company (the “Bank”). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Credit Agreement. The Credit Agreement provides for a revolving line of credit whereby Borrower may borrow up to $35.0 million (the “Revolving Line”) with an additional $15.0 million to be advanced under the Revolving Line at the sole discretion of the Bank. The Revolving Line is secured on a first priority basis by Borrower’s assets. Any newly formed or acquired subsidiary of Borrower or any Guarantor, will either join the Credit Agreement as a co-borrower or become a Guarantor under the Credit Agreement, as determined by the Bank in its sole discretion. Borrower intends to use the Revolving Line for working capital and general business purposes. The Revolving Line terminates, and any outstanding principal amount of all advances made thereunder, and any accrued and unpaid interest thereon, become immediately due and payable on the earlier of (a) the three year anniversary of the Closing Date and (b) the date that is within 90 days of the maturity date of the “2026 Convertible Note” if such notes are outstanding as of such date. “2026 Senior Convertible Note” means the existing unsecured Indebtedness issued pursuant to that certain Indenture between the Company as issuer and UMB Bank, National Association as Indenture Trustee dated as of February 5, 2021, which provide for the issuance from time to time of debentures, notes or other debt instruments of Borrower, to be issued in one or more series. Borrowings under the Credit Agreement generally bear interest at a variable rate equal to (a) term SOFR plus a specified margin or (b) WSJ prime plus a specified margin, in each case which will be adjusted based on the Company’s net leverage ratio at the time of borrowing.

Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company as of December 31, 2023 have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and, accordingly, they do not include all information and footnote disclosures required by accounting principles generally accepted in the U.S. (“GAAP”). The Company believes the footnotes and other disclosures made in the financial statements are adequate for a fair presentation of the results of the interim periods presented. The financial statements include all adjustments (solely of a normal recurring nature) which are, in the opinion of management, necessary to make the information presented not misleading. You should read these financial statements and the accompanying notes in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2023, filed with the U.S. Securities and Exchange Commission (“SEC”) on March 19, 2024. Results for the three months ended December 31, 2023, are not necessarily indicative of results for any other interim period or for a full fiscal year.
Principles of Consolidation	Principles of Consolidation
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, deferred taxes, and related disclosure of contingent assets and liabilities. On an ongoing basis, management reviews its estimates based upon currently available information. Actual results could differ materially from those estimates. These estimates include, but are not limited to, assessing the collectability of accounts receivable, estimation of the value of stock-based compensation awards, fair value of assets and liabilities acquired, impairment of goodwill, useful lives of intangible assets, fair value of debt derivatives, standalone selling price related to revenue recognition, contingent consideration, and income taxes.

Recently Adopted Accounting Pronouncements, Change in Significant Accounting Policy and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements The Company did not adopt any new accounting pronouncements in the quarter ended December 31, 2023. Change in Significant Accounting Policy The Company’s significant accounting policies are disclosed in the Company’s audited condensed consolidated financial statements and related notes thereto included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2023, filed with the SEC on March 19, 2024. There have been no changes to these accounting policies through December 31, 2023. Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures amending existing income tax disclosure guidance, primarily requiring more detailed disclosure for income taxes paid and the effective tax rate reconciliation. The ASU is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted and can be applied on either a prospective or retroactive basis. The Company is currently evaluating the ASU to determine its impact on its income tax disclosures. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (ASU 2020-04) and also issued subsequent amendments to the initial guidance (collectively, Topic 848). Topic 848 provides optional guidance for contract modifications and certain hedging relationships associated with the transition from reference rates that are expected to be discontinued. The Company will adopt Topic 848 when the relevant contracts are modified upon transition to alternative reference rates. The Company does not expect the adoption of Topic 848 will have a material impact on the condensed consolidated financial statements. No other new accounting pronouncement issued or effective during the three months ended December 31, 2023 had, or are expected to have, a material impact on the Company’s condensed consolidated financial statements.
Revenue Recognition	Nature of Goods and Services The following is a description of principal activities from which the Company generates its revenue. Contracts with customers are evaluated on a contract-by-contract basis as contracts may include multiple types of goods and services as described below. Software and Hardware Software and hardware revenue is generated from on premise software license sales, as well as sales of hardware scanner boxes and on premise appliance products. Software is typically sold as a time-based license with a term of one Services and Other Services and other revenue is generated from the sale of software as a service (“SaaS”) products and services, maintenance associated with the sale of on premise software licenses and consulting and professional services. The Company’s SaaS offerings give customers the option to be charged upon their incurred usage in arrears (“Pay as You Go”), or commit to a minimum spend over their contracted period, with the ability to purchase unlimited additional transactions above the minimum during the contract term. Revenue related to Pay as You Go contracts are recognized based on the customer’s actual usage, in the period of usage. For contracts which include a minimum commitment, the Company is standing ready to provide as many transactions as desired by the customer throughout the contract term, and revenue is recognized on a ratable basis over the contract period including an estimate of usage above the minimum commitment. Usage above minimum commitment is estimated by looking at historical usage, expected volume, and other factors to project out for the remainder of the contract term. The estimated usage-based revenues are constrained to the amount the Company expects to be entitled to receive in exchange for providing access to its platform. If professional services are deemed to be distinct, revenue is recognized as services are performed. The Company does not view the signing of the contract or the provision of initial setup services as discrete earnings events that are distinct. Significant Judgments in Application of the Guidance The Company uses the following methods, inputs, and assumptions in determining amounts of revenue to recognize: Identification of Performance Obligations For contracts that contain multiple performance obligations, which include combinations of software licenses, maintenance, and services, the Company accounts for individual goods or services as a separate performance obligation if they are distinct. The good or service is distinct if the good or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. Determination of Transaction Price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The Company includes any fixed charges within its contracts as part of the total transaction price. To the extent that variable consideration is not constrained, the Company includes an estimate of the variable amount, as appropriate, within the total transaction price and updates its assumptions over the duration of the contract. As a practical expedient, the Company does not adjust the transaction price for the effects of a significant financing component if, at contract inception, the period between customer payment and the transfer of goods or services is expected to be one year or less. Assessment of Estimates of Variable Consideration Many of the Company’s contracts with customers contain some component of variable consideration; however, variable consideration will only be included in the transaction price to the extent it is probable that a significant reversal of revenues recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company may constrain the estimated transaction price in the event of a high degree of uncertainty as to the final consideration amount owed because of an extended length of time over which the fees may be adjusted or due to uncertainty surrounding collectability. The Company estimates variable consideration in its contracts primarily using the expected value method as the Company believes this method represents the most appropriate estimate for this consideration, based on historical usage trends, the individual contract considerations, and its best judgment at the time. Allocation of Transaction Price The transaction price, including any discounts, is allocated between separate goods and services in a contract that contains multiple performance obligations based on their relative standalone selling prices. The standalone selling prices are based on the prices at which the Company separately sells each good or service. For items that are not sold separately, the Company estimates the standalone selling prices using available information such as market conditions and internally approved pricing guidelines. In certain situations, primarily transactional SaaS revenue described above, the Company allocates variable consideration to a series of distinct goods or services within a contract. The Company allocates variable payments to one or more, but not all, of the distinct goods or services or to a series of distinct goods or services in a contract when (i) the variable payment relates specifically to the Company’s efforts to transfer the distinct good or service and (ii) the variable payment is for an amount that depicts the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods or services to its customer.
