Convertible Senior Notes
The carrying values of the 0.75% convertible notes due February 1, 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, 2025September 30, 2025
Principal amount$155,250 $155,250 
Less: unamortized discount and issuance costs, net of amortization(786)(3,034)
Carrying amount$154,464 $152,216 
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 were issued pursuant to an Indenture, dated February 5, 2021 (the “Indenture”), between the Company and UMB Bank, National Association, as trustee. The Indenture included customary covenants and sets forth certain events of default after which the 2026 Notes could 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 became 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 $20.3 million aggregate principal amount of the 2026 Notes (the “Additional Notes”), which was exercised in full. As of December 31, 2025, the Company was in compliance with the covenants in the Indenture.
After August 1, 2025, the 2026 Notes were convertible at the option of the holders at any time prior to the close of business on the maturity date. 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 a portion of the net proceeds from the offering to pay the cost of the Notes Hedge (as defined below), after such cost was partially offset by the proceeds from the Warrant Transactions (as defined below). As of December 31, 2025, the number of authorized and unissued shares of Common Stock that were not reserved for other purposes was sufficient to settle the 2026 Notes into equity. Accordingly, the Company had the option to 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, that was subsequently reclassified to additional paid-in capital when 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. 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.
As of December 31, 2025, 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 2026 Notes bore interest from February 5, 2021 at a rate of 0.75% per year payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2021. The following table presents the total amount of interest cost recognized relating to the 2026 Notes (amounts in thousands):
Three Months Ended December 31,

Contractual interest expense$293 $293 
Amortization of debt discount and issuance costs2,249 2,105 
Total interest expense recognized$2,542 $2,398 

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 $0.8 million as of December 31, 2025, and will be amortized over approximately 0.1 years. The fair value, based on a quoted market price (Level 2), of the 2026 Notes at December 31, 2025 was approximately $154.8 million.

The Company repaid the 2026 Notes in full in the second quarter of fiscal 2026.
Convertible Senior Notes Hedge and Warrants
In connection with the issuance of the 2026 Notes, the Company entered into transactions for convertible notes hedge (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.
As of December 31, 2025, the Notes Hedge of $33.2 million 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. The Notes Hedge expired on February 1, 2026, without the Company exercising any option to acquire Common Stock.
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, 2025, 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, 2025, the Warrant Transactions had not been exercised and remained outstanding.
Amended Credit Agreement - Revolving Credit Line and Term Loan
On May 7, 2025, the Company, together with its subsidiaries, A2iA Corp. and ID R&D, Inc., entered into the First Amendment to Loan and Security Agreement (the “Amendment”), amending the Credit Agreement, and as amended by the Amendment (the “Amended Credit Agreement”), by and among the Company and the Bank.
The Amended Credit Agreement provides for, among other things, (i) the establishment of a delayed draw term loan (the “Term Loan”) in an aggregate principal amount of up to $75.0 million that may be drawn prior to February 28, 2026 for the sole purpose of paying amounts outstanding under the 2026 Notes due February 1, 2026 and customary fees and expenses in connection therewith, (ii) a revolving line of credit (the “Revolving Line”) whereby the Company may borrow up to $25.0 million with an additional $15.0 million to be advanced under the Revolving Line at the sole discretion of the Bank. On January 21, 2026, the Company borrowed $50.0 million under its Term Loan. The Term Loan and Revolving Line are secured on a first priority basis by the Company’s assets.
In connection with the Amended Credit Agreement, the Company incurred issuance costs of $0.2 million which were recorded to Other income (expense), net. The Term Loan and the Revolving Line both mature on May 1, 2030. Commencing on April 1, 2026, the Borrower must make amortization payments on any advances under the Term Loan at the percentages set forth in the Amendment.
Borrowings under the Amended 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. Borrower must also pay the Bank (i) a commitment fee of $125,000 and (ii) an “Unused Revolving Line Facility Fee” of 0.25% per annum of the average unused portion of the Revolving Line.
The Amended Credit Agreement contains representations, warranties, and negative and affirmative covenants customary for transactions of this type. These include covenants limiting the ability of Borrower and any of their subsidiaries, subject to certain exceptions and baskets, to, among other things, (i) incur indebtedness, (ii) incur liens on their assets, (iii) enter into any merger or consolidation with, or acquire all or substantially all of the equity or property of, another person, (iv) dispose of any of their business or property, (v) make or permit any payment on subordinated debt, or (vi) pay any dividend, make any other distribution, or redeem any equity.
The Amended Credit Agreement contains customary events of default and also provides that an event of default includes any default resulting in a right by third parties to accelerate maturity of indebtedness in excess of $500,000. If any event of default occurs and is not cured within applicable grace periods set forth in the Amended Credit Agreement or waived, all loans and other obligations could become due and immediately payable and the facility could be terminated. In addition, Borrower may be required to deposit cash with the Bank in an amount equal to 1.05 of any undrawn letters of credit denominated in U.S. Dollars or 1.15 of any undrawn letters of credit denominated in a foreign currency.
The Amended Credit Agreement requires the Company to maintain a net leverage ratio of no more than 2.50 to 1.00 and if the Company consummates a permitted acquisition during the trailing twelve-month period, the net leverage ratio may not exceed 2.75 to 1.00. As of December 31, 2025, the Company was in compliance with the net leverage ratio covenant of the Amended Credit Agreement. There are no outstanding borrowings under the Amended Credit Agreement as of December 31, 2025.
