CONVERTIBLE SENIOR NOTES, TERM LOAN AND CAPPED CALLS

2024 Notes

In February 2019, the Company issued $287.5 million aggregate principal amount of 0.50% convertible senior notes due 2024 (the "Initial 2024 Notes") in a private placement, including the exercise in full of the initial purchasers' option to purchase additional notes. The total net proceeds from the debt offering, after deducting initial purchase discounts, debt issuance costs, and costs of the capped call transactions described below, were approximately $245.8 million.

In November 2019, the Company issued an additional $75.0 million aggregate principal amount of 0.50% convertible senior notes due 2024 (the "First Additional 2024 Notes") in a registered offering under the same indenture as the Initial 2024 Notes. The total net proceeds from the First Additional 2024 Notes, after deducting underwriting discounts, debt issuance costs, and costs of the capped call transactions described below, were approximately $64.6 million.

In December 2021, the Company issued an additional $137.5 million aggregate principal amount of its currently outstanding 0.50% convertible senior notes due 2024 (the "Second Additional 2024 Notes", and together with the Initial 2024 Notes and the First Additional 2024 Notes, the "2024 Notes") in a private placement under the same indenture as the Initial 2024 Notes and the First Additional 2024 Notes. The total net proceeds from the Second Additional 2024 Notes, after deducting initial purchase discounts and debt issuance costs, were approximately $134.3 million. The Company did not enter into any capped calls in connection with this transaction. Both the First Additional 2024 Notes and Second Additional 2024 Notes constitute a further issuance of, and form a single series with, the Initial 2024 Notes. Immediately after giving effect to the issuance of the Second Additional 2024 Notes, the Company had $500.0 million aggregate principal amount of convertible senior notes. For details on the net carrying amount and fair value of the liability component of the 2024 Notes, as well as the interest expense recognized related to the 2024 Notes, see the section entitled “Exchange Transaction and 2028 Notes” below.

The 2024 Notes are senior unsecured obligations of the Company and interest is payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2019. The Notes will mature on February 1, 2024, unless earlier repurchased, redeemed, or converted.

Each $1,000 principal amount of the 2024 Notes is initially convertible into 38.9484 shares of the Company’s common stock, par value $0.001, which is equivalent to an initial conversion price of approximately $25.68 per share. The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of certain corporate events that occur prior to the maturity date or following the Company's issuance of a notice of redemption, in each case as described in the Indenture, the Company will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Notes in connection with such a corporate event or during the relevant redemption period.

Prior to the close of business on the business day immediately preceding October 1, 2023, the 2024 Notes will be convertible only under the following circumstances:

1.At any time during any calendar quarter commencing after the fiscal quarter ending on June 30, 2019 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

2.During the five business day period immediately after any ten consecutive trading day period (the measurement period), if the trading price per $1,000 principal amount of the 2024 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the common stock on each such trading day and the conversion rate on each such trading day;

3.If the Company calls any or all of the Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

4.Upon the occurrence of specified corporate events (as set forth in the indenture governing the 2024 Notes).

On or after October 1, 2023, 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 2024 Notes, regardless of the foregoing circumstances. Upon conversion, the Company will satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, at the Company's election. The Company’s current intent is to settle the principal amount of the 2024 Notes in cash upon conversion. During the year ended March 31, 2023, the conditions allowing holders of the 2024 Notes to convert were not met.

Under the terms of the 2024 Notes, the Company could not redeem the 2024 Notes prior to February 4, 2022. On or after February 4, 2022, the Company may redeem for cash all or part of the 2024 Notes at the redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if the last reported sale price of the common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides a redemption notice. If a fundamental change (as defined in the indenture governing the notes) occurs at any time, holders of 2024 Notes may require the Company to repurchase for cash all or any portion of their 2024 Notes at a repurchase price equal to 100% of the principal amount of the 2024 Notes to be repurchased, plus accrued and unpaid interest, but excluding, the fundamental change repurchase date.

The 2024 Notes are senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 2024 Notes; equal in right of payment with the Company’s existing and future liabilities that are not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of current or future subsidiaries of the Company.

Prior to April 1, 2022, the Company accounted for the 2024 Notes as separate liability and equity components. On issuance, the carrying amount of the equity components was recorded as a debt discount and subsequently amortized to interest expense. Effective April 1, 2022, the Company adopted ASU 2020-06 using a modified retrospective approach. As a result, the 2024 Notes are accounted for as a single liability measured at its amortized cost, as no other embedded features require bifurcation and

recognition as derivatives. Adoption of the new standard resulted in a decrease to accumulated deficit of $46.7 million, a decrease to additional paid-in capital of $92.8 million and an increase to convertible senior notes, net of $46.2 million. The 2024 Notes have no original issuance discounts. Unamortized debt discount and issuance costs will be amortized over the remaining life of the 2024 Notes, which is approximately nine months.

Capped Calls

In connection with the pricing of the Initial 2024 Notes and the First Additional 2024 Notes, the Company entered into privately negotiated capped call transactions (the "Capped Calls") with certain counterparties. The Capped Calls each have an initial strike price of approximately $25.68 per share, subject to certain adjustments, which correspond to the initial conversion price of the Initial 2024 Notes and the First Additional 2024 Notes. The Capped Calls have initial cap prices of $39.50 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 14.1 million shares of the Company’s common stock. In February 2023, the Company unwound the Capped Calls and received $0.2 million in cash, which was recorded as Additional Paid in Capital.

Term Loan and Warrants

On August 10, 2022, the Company borrowed $250.0 million in a senior secured term loan facility (the “Term Loan”) under a term loan credit agreement (the “Credit Agreement”) entered into on August 3, 2022 with Wilmington Savings Fund Society, FSB, as administrative agent, and certain affiliates of Francisco Partners (“FP”), with aggregate debt issuance costs and discount of approximately $20.0 million, including $2.8 million paid in the form of shares of the Company's common stock. The Term Loan matures on August 3, 2027 and will initially bear interest at an annual rate equal to the term Standard Overnight Financing Rate ("Term SOFR") (which will be subject to a floor of 1.00% and a credit spread adjustment of 0.10%), plus a margin of 6.50%.

The obligations under the Credit Agreement will be guaranteed by the Company’s wholly-owned subsidiaries, subject to certain customary exceptions, and secured by a perfected security interest in substantially all of the Company’s tangible and intangible assets, as well as substantially all of the tangible and intangible assets of the guarantors.

Mandatory prepayments of the Term Loan are required to be made upon the occurrence of certain events, including, without limitation, (i) sales of certain assets, (ii) receipt of certain casualty and condemnation awards proceeds, and (iii) the incurrence of non-permitted indebtedness, subject to certain thresholds and reinvestment rights. Voluntary prepayments are permitted at any time, subject to certain prepayment premiums.

The Credit Agreement contains a minimum adjusted cash Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) financial covenant, a minimum liquidity covenant and a maximum secured leverage ratio financial covenant and contains affirmative and negative covenants customary for transactions of this type, including limitations with respect to indebtedness, liens, investments, dividends, disposition of assets, change in business, and transactions with affiliates.

The Company used the proceeds from the issuance of the Term Loan to fund the cash portion of an exchange of the Company’s approximately $403.8 million principal amount of the 2024 Notes for cash plus approximately $201.9 million of the 2028 Notes (defined below), and the concurrent repurchase of approximately $60.0 million of the Company’s common stock with the counterparties to such exchange.

In connection with the Credit Agreement, the Company issued detachable warrants (the “Warrants”) to affiliates of FP to purchase an aggregate of 3.1 million shares of the Company’s common stock with a five-year term and an exercise price of $7.15 per share (subject to adjustment) that represents a 27.5% premium over the closing price per share of the Company’s common stock on August 3, 2022. The Warrants are classified as liabilities as the Warrants contain certain terms that could result in cash settlement as a result of events outside of the Company’s control. Accordingly, the Company recognizes the Warrants as liabilities at fair value initially and adjusts the Warrants to fair value at each reporting period. The fair value of the Warrants was $5.9 million upon issuance, and $5.5 million at March 31, 2023, and was recorded within Other liabilities, non-current on the condensed consolidated balance sheets with a corresponding debt discount recorded against the Term Loan. The subsequent changes in fair value were recorded through Other income (expense), net on the Company’s condensed consolidated statement of operations.

The debt discount and debt issuance costs are amortized to interest expense over the term of the Term Loan at an effective interest rate of 11.0%.

The following table presents the net carrying amount of the Term Loan:

Principal	$	250,000
Unamortized debt discount and issuance costs	(18,007)

Exchange Transaction and 2028 Notes

Exchange Transaction

On August 11, 2022, the Company issued approximately $201.9 million aggregate principal amount of its 4.00% convertible senior notes due 2028 (the “2028 Notes”), pursuant to an indenture, dated as of August 11, 2022 (the “2028 Notes Indenture”), by and between the Company and Wilmington Trust, National Association, as trustee (the “Trustee”).

The Company used the proceeds from the issuance of the 2028 Notes, together with approximately $181.8 million in cash consideration from borrowing of the Term Loan, in exchange for approximately $403.8 million aggregate principal amount of the Company’s outstanding 2024 Notes pursuant to privately negotiated agreements (the “Exchange Agreements”) with a limited number of existing holders of the 2024 Notes (the “Exchange Transaction”). In connection with the Exchange Transaction, the Company purchased an aggregate of approximately $60.0 million of the Company’s common stock in privately negotiated transactions from existing holders of the 2024 Notes who participated in the Exchange Transaction.

The Exchange Transaction was treated as a debt extinguishment. The difference between the consideration used to extinguish the 2024 Notes and the carrying value of the 2024 Notes (including unamortized debt discount and issuance costs) subject to the Exchange Transaction resulted in an extinguishment gain of $16.1 million recorded through Other income (expense), net on the Company’s condensed consolidated statement of operations.

The Capped Calls were not modified or settled as part of the Exchange Transaction and continued to be classified in stockholders' equity as long as they continued to meet the conditions for equity classification. These were subsequently unwound in February 2023.

2028 Notes

As part of the Exchange Transaction, the Company issued $201.9 million aggregate principal amount of the 2028 Notes, with debt issuance costs of approximately $5.6 million, of which 50% was paid in the form of shares of the Company's common stock.

The 2028 Notes are senior obligations of the Company that accrue interest, payable semi-annually in arrears on February 1 and August 1 of each year, commencing on February 1, 2023. The 2028 Notes will mature on February 1, 2028, unless earlier converted, redeemed or repurchased. The initial conversion rate is 139.8064 shares of the Company’s common stock per $1,000 principal amount of the 2028 Notes (equivalent to an initial conversion price of approximately $7.15 per share), subject to customary adjustments. Upon conversion of the 2028 Notes, the Company may elect to satisfy the conversion obligation by cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s stock.

Prior to the close of business on the business day immediately preceding November 15, 2027, the 2028 Notes will be convertible only under the following circumstances:

1.At any time during any fiscal quarter commencing after the fiscal quarter ending on December 31, 2022 (and only during such fiscal quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

2.During the five business day period immediately after any five consecutive trading day period (the measurement period), if the trading price per $1,000 principal amount of the 2028 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the common stock and the conversion rate on each such trading day;

3.If the Company calls any or all of the 2028 Notes for redemption prior to the close of business on the business day immediately preceding November 15, 2027; or

4.Upon the occurrence of specified corporate events (as set forth in the 2028 Notes Indenture).

On or after November 15, 2027, holders of the 2028 Notes may convert their 2028 Notes at their option at any time until the close of business on the second Scheduled Trading Day immediately preceding the maturity date.

Under the terms of the 2028 Notes, the Company cannot redeem the 2028 Notes prior to August 6, 2025. On or after August 6, 2025, the Company may, at its option, redeem for cash all or any portion of the 2028 Notes at a redemption price equal to 100% of the principal amount, plus accrued unpaid interest, only upon the satisfaction of certain conditions and during certain periods,

including if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides a redemption notice.

If a fundamental change (as defined in the 2028 Notes Indenture) occurs at any time prior to February 1, 2028, holders of 2028 Notes may require the Company to repurchase for cash all or any portion of their 2028 Notes at a repurchase price equal to 100% of the principal amount of the 2028 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date. In addition, in connection with certain corporate events or if the Company issues a notice of redemption, a fundamental change will, under certain circumstances, increase the conversion rate for holders who elect to convert their 2028 Notes in connection with such corporate event or during the relevant redemption period.

The 2028 Notes Indenture contains customary terms and covenants, including that upon certain events of default occurring and continuing, either the Trustee or holders of no less than 25% in aggregate principal amount of the 2028 Notes then outstanding may declare the entire principal amount of all the 2028 Notes, and the interest accrued on such 2028 Notes, if any, to become immediately due and payable. Upon events of default in connection with specified bankruptcy events involving the Company, the 2028 Notes will become due and payable immediately.

The debt discount and debt issuance costs are amortized to interest expense over the term of the 2028 Notes at an effective interest rate of 4.7%.

The following table presents the net carrying amount of the 2028 Notes:

	March 31, 2023
Principal	$	201,914
Unamortized debt discount and issuance costs	(5,093)
Net carrying amount	$	196,821

Repayment of 2024 Notes

In addition to the Exchange Transaction, the Company completed three repurchases of the 2024 Notes during fiscal 2023 for a total of approximately $32.9 million in aggregate principal amount.

On September 28, 2022, the Company repurchased an aggregate principal amount of $6.0 million of the 2024 Notes through a privately negotiated transaction with one of the remaining 2024 Notes holders for an aggregate purchase price of $5.3 million. The aggregate purchase price was paid in cash and only partially settled the outstanding 2024 Notes with the holder; accordingly, the repurchase consideration was accounted for as a debt modification with no extinguishment gain or loss.

On December 9, 2022, the Company repurchased an aggregate principal amount of $21.8 million of the 2024 Notes through privately negotiated transactions with two of the remaining 2024 Notes holders for an aggregate purchase price of $20.1 million in cash. The repurchase consideration was accounted for as a debt extinguishment, resulting in a $2.1 million gain.

On February 23, 2023, the Company repurchased an aggregate principal amount of $5.0 million of the 2024 Notes through a privately negotiated transaction with one of the remaining 2024 Notes holders for an aggregate purchase price of $4.7 million in cash. The repurchase consideration was accounted for as a debt extinguishment, resulting in a $0.3 million gain.

The following table presents the net carrying amount and fair value of the liability component of the 2024 Notes:

	March 31, 2023		March 31, 2022
Principal	$	63,295	$	500,000
Unamortized debt discount(1) and issuance costs	(363)		(52,548)
Net carrying amount	$	62,932	$	447,452

(1) The debt discount as of March 31, 2022 represents the discount resulting from the allocation of the equity component (conversion option) from the liability component of the 2024 Notes, net of issuance premium, prior to the adoption of ASU 2020-06 on April 1, 2022. Upon the adoption of ASU 2020-06, the equity component was reversed. As a result, the March 31, 2023 debt discount represents only the issuance premium.

The debt discount and debt issuance costs are amortized to interest expense over the term of the 2024 Notes at an effective interest rate of 1.2%.

Interest expense recognized related to the 2024 Notes was as follows:

	Years Ended March 31,
	2023		2022		2021
Contractual interest expense	$	1,177	$	2,271	$	1,813
Amortization of debt discount and issuance costs	1,694		20,404		16,898
