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 (as defined below) of the 2026 Notes 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.

The 2026 Notes will mature on February 1, 2026, unless earlier redeemed, repurchased or converted. The 2026 Notes will 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 the Company’s common stock, $0.001 par value (the “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). 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 March 31, 2021, the number of authorized and unissued shares of the Company’s common stock that are not reserved for other purposes is less than the maximum number of underlying shares that will be required to settle the 2026 Notes into equity. Accordingly, unless and until the Company has a number of authorized shares that have not been issued or reserved for any other purpose that equals or exceeds the maximum number of underlying shares (“share reservation condition”), the Company will pay to the converting holder in respect of each $1,000 principal amount of notes being converted solely cash in an amount equal to the sum of the daily conversion values for each of the 40 consecutive trading days during the related observation period. However, following satisfaction of the share reservation condition, the Company may settle conversions of notes through payment or delivery, as the case may be, of cash, shares of the Company’s common stock or a combination of cash and shares of its 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 are first allocated to the embedded derivative liability and the remaining proceeds are 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 March 31, 2021, the embedded derivative liability is included in embedded conversion derivative in the consolidated balance sheet and the change in fair value of derivative is included in Other income, net in the consolidated statement of operations. The carrying amount of the embedded derivative liability was determined using a Black-Scholes option valuation model.

The following table presents the fair value and the change in fair value for the embedded conversion derivative (in thousands):


Embedded conversion derivative
Fair value as of February 5, 2021	$	33,192
Change in fair value	1,527
Fair value as of March 31, 2021	$	34,719

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 (in thousands):


	Three Months Ended March 31,				Six Months Ended March 31,
	2021		2020		2021		2020
Contractual interest expense	$	172	$	—	$	172	$	—
Amortization of debt discount and issuance costs	1,147		—		1,147		—
Total interest expense recognized	$	1,319	$	—	$	1,319	$	—

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 $37.6 million as of March 31, 2021, and will be amortized over approximately 4.8 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 corresponds 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 the Company is required to settle the Notes Hedge in cash, they do not qualify for the scope exception for contracts involving an issuer’s own equity in ASC 815 and have been accounted for as a derivative asset. Upon initial purchase, the Notes Hedge was recorded in our consolidated balance sheets in convertible senior notes hedge at $33.2 million. As of March 31, 2021, the Notes Hedge is included in convertible senior notes hedge in the consolidated balance sheet and the change in fair value is included in Other income, net in the consolidated statement of operations. As of March 31, 2021, 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 March 31, 2021, 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 March 31, 2021, the Warrant Transactions had not been exercised and remained outstanding.
