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:	June 30, 2024		September 30, 2023
Principal amount	$	155,250	$	155,250
Less: unamortized discount and issuance costs, net of amortization	(13,719)		(19,734)
Carrying amount	$	141,531	$	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 (the “Q1 Form 10-Q”) with the SEC. The Company filed its Form 10-K with the SEC on March 19, 2024 and its Q1 Form 10-Q with the SEC on April 15, 2024. As of June 30, 2024, the Company was in compliance with the covenants in the Indenture.

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 0.75% 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 (as defined below), 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).

As of June 30, 2024, 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 has 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, 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 June 30, 2024, 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 June 30,				Nine Months Ended June 30,
	2024		2023		2024		2023
Contractual interest expense	$	289	$	454	$	880	$	1,053
Amortization of debt discount and issuance costs	2,040		1,908		6,015		5,609
Total interest expense recognized	$	2,329	$	2,362	$	6,895	$	6,662

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 $13.7 million as of June 30, 2024, and will be amortized over approximately 1.6 years. The fair value, based on a quoted market price (Level 2), of the 2026 Notes at June 30, 2024 was approximately $147.4 million.

Convertible Senior Notes Hedge and Warrants

In connection with the pricing 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.

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 at $33.2 million in our condensed consolidated balance sheets. 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 Notes Hedge to additional paid-in capital.

As of June 30, 2024, 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 June 30, 2024, 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 June 30, 2024, the Warrant Transactions had not been exercised and remained outstanding.

Revolving Credit Line

On February 13, 2024, the Company entered into a Loan and Security Agreement (the “Credit Agreement”) with Silicon Valley Bank, a division of First-Citizens Bank & Trust Company (the “Bank”) that provides for a revolving line of credit whereby the Company 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 the Company’s assets. In connection with the Credit Agreement, the Company incurred issuance costs of $0.3 million which will be amortized to interest expense using the straight-line method over the term of the Credit Agreement.

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 Notes if such notes are outstanding as of such date.

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. The Company must also pay the Bank (i) a commitment fee of $87,500 and (ii) an “Unused Revolving Line Facility Fee” of 0.25% per annum of the average unused portion of the Revolving Line.

The Credit Agreement contains representations, warranties, and negative and affirmative covenants customary for transactions of this type. These include covenants limiting the ability of the Company, 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 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 Credit Agreement or waived, all loans and other obligations could become due and immediately payable and the facility could be terminated. In addition, the Company may be required to deposit cash with the Bank in an amount equal to 115% of any undrawn letters of credit denominated in a foreign currency.

The Credit Agreement requires the Company to maintain a net leverage ratio of no more than 2.25 to 1.00 and if the Company engages in a share repurchase program, the net leverage ratio may not exceed 2.00 to 1.00. As disclosed in Note 6, on May 13, 2024, the Board authorized and approved a share repurchase program for up to $50.0 million of the currently outstanding shares of Common Stock. As of June 30, 2024 the Company’s net leverage ratio was 2.02 to 1.00 and as such the Company was not in compliance with the net leverage ratio covenant of the Credit Agreement. The Company obtained a waiver from the Bank which covers the compliance period ended June 30, 2024. Additionally, as there are no outstanding borrowings under the Credit Agreement, the Company’s waived non-compliance did not trigger any adverse impacts on the Credit Agreement or the 2026 Notes.

Other Borrowings

The Company has certain loan agreements with Spanish government agencies. These agreements have repayment periods of five to twelve years and bear no interest. As of June 30, 2024, $2.3 million was outstanding under these agreements and $0.2 million and $2.1 million is recorded in other current liabilities and other non-current liabilities, respectively, in the condensed consolidated balance sheets. As of September 30, 2023, $1.3 million was outstanding under these agreements and approximately $0.2 million and $1.1 million is recorded in other current liabilities and other non-current liabilities, respectively, in the condensed consolidated balance sheets.
