Convertible Notes

Convertible NotesIn November 2020, the Company issued $280.0 million aggregate principal amount of 4.0% senior subordinated convertible notes due November 2025. The net proceeds the Company received from the offering was approximately $271.1 million, after deducting the initial purchasers’ discounts and commissions and offering expenses payable by the Company (the "Convertible Notes"). The Company used approximately $46.0 million of the net proceeds from the offering of the notes to pay the cost of the Capped Call (as defined below) and $55.0 million of the net proceeds from the offering of the initial notes to finance the Prepaid Forward (as defined below). The Convertible Notes are the Company's senior unsecured obligations and mature on November 15, 2025 (the “Maturity Date”), unless earlier repurchased or converted into shares of common stock under certain circumstances described below. The Convertible Notes are convertible into shares of the Company’s common stock, can be repurchased for cash, or a combination thereof, at the Company’s election, at an initial conversion rate of 30.2151 shares of common stock per $1,000 principal amount of the Convertible Notes, which is equivalent to an initial conversion price of approximately $33.096 per share of common stock, subject to adjustment. The Company will pay interest on the Convertible Notes semi-annually in arrears on May 15 and November 15 of each year.

The Convertible Notes are general unsecured obligations of the Company that are subordinated in right of payment to indebtedness, obligations and other liabilities under the Company’s RIPA, the revenue interests issued pursuant to such agreement, and any refinancing of the foregoing.

Holders may convert their Convertible Notes at their option at any time prior to the close of business on the business day immediately preceding August 15, 2025 in the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ended on March 31, 2021 (and only during such calendar quarter), if the last reported sale price per share of the Company’s common stock, par value $0.001 per share (“common stock”), is greater than or equal to 130% of the conversion price for each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter; (2) during the five business days 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 Company’s common stock and the conversion rate for the notes on each such trading day; (3) if the Company calls such notes for redemption, any such notes that have been called for redemption may be converted at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date, but only with respect to the notes called for redemption; and (4) upon the occurrence of specified corporate events, as provided in the Indenture. On or after August 15, 2025, to the close of business on the second scheduled trading day immediately before the maturity date, holders may convert all or any portion of their notes at the applicable conversion rate at any time at the option of the holder regardless of the foregoing conditions.

In addition, following certain corporate events or following issuance of a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or to convert its notes called (or deemed called) for redemption during the related redemption period, as the case may be.

The Convertible Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after November 20, 2023 and before the 41st scheduled trading day immediately before the maturity date, at a cash redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share 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), including the trading day immediately preceding the date the Company sends the related redemption notice, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company sends such redemption notice. No sinking fund is provided for the notes. If the Company redeems less than all the outstanding notes, at least $125.0 million aggregate principal amount of notes must be outstanding and not subject to redemption as of the relevant redemption notice date.

If the Company undergoes a “fundamental change” (as defined in the Indenture), holders may require the Company to repurchase their notes for cash all or any portion of their notes at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, to, but excluding, the fundamental change repurchase date. The Indenture includes customary terms and covenants, including certain events of default.

The Company incurred approximately $8.9 million of issuance costs related to the issuance of the Convertible Notes, of which, prior to the adoption of Accounting Standards Update ("ASU") 2020-06 on January 1, 2021, $5.8 million and $3.1 million were allocated and recorded to long-term debt and additional paid-in capital, respectively. The $5.8 million of issuance costs recorded as long-term debt on the condensed balance sheet was to be amortized over the five-year contractual term of the Convertible Notes using the effective interest method.

Prior to the adoption of ASU 2020-06 on January 1, 2021, the $271.1 million of proceeds received from the issuance of the Convertible Notes were allocated between long-term debt (the “liability component”) of $177.6 million and additional paid-in capital (the “equity component”) of $93.5 million. The fair value of the liability component was measured using rates determined for similar debt instruments without a conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the aggregate face value of the Convertible Notes and was included in additional paid-in capital in the condensed balance sheet and was not remeasured as long as it did not to meet the conditions for equity classification. The liability component was to be accreted up to the face value of the Convertible Notes of $280.0 million, which resulted in additional non-cash interest expense being recognized through the Maturity Date.

With the adoption of ASU 2020-06 as of January 1, 2021, the Company reports the convertible debt liability at the aggregate principal amount less unamortized issuance costs. This resulted in the reclassification of the $93.5 million of the Company’s convertible notes recognized at December 31, 2020 from additional paid in capital to the convertible debt liability.

The portion of interest expense previously recognized for the accretion of the convertible debt liability and the true-up of the amortization of the issuance costs of $1.5 million was recorded as an adjustment to accumulated deficit.

On October 22, 2021, the Company entered into a privately negotiated exchange agreement (the “Exchange Agreement”) with two co-managed holders (the “Holders”) of its Convertible Notes. Under the terms of the Exchange Agreement the Holders agreed to exchange (the “Exchange”) with the Company $15.0 million aggregate principal amount of the Convertible Notes held in the aggregate by them (and accrued interest thereon) for shares of the Company’s common stock. Pursuant to the Exchange Agreement, the number of shares of common stock to be issued by the Company to the Holders upon consummation of the Exchange was determined based upon the volume-weighted-average-price per share of common stock, subject to a floor of $5.62 per share, during the five trading-day averaging period, commencing on the trading day immediately following the date of the Exchange Agreement. The Exchange closed on November 3, 2021, with 1,094,848 shares of the Company's common stock being exchanged.

As of September 30, 2022, the principal amount of convertible notes was $265.0 million, and the unamortized debt discount and issuance costs were $5.5 million, for a net carrying amount of $259.5 million.

The Company recorded $3.1 million and $9.2 million of interest expense during the three and nine months ended September 30, 2022, respectively, and $3.2 million and $9.6 million of interest expense during the three and nine months ended September 30, 2021, respectively, relating to the cash interest on the convertible notes due semi-annually and amortization of the debt issuance costs.

As of September 30, 2022, no Convertible Notes were convertible pursuant to their terms. The estimated fair value of the Convertible Notes was $148.9 million as of September 30, 2022 and $140.3 million as of December 31, 2021. The estimated fair value of the Convertible Notes was determined through consideration of quoted market prices. As of September 30, 2022, the if-converted value of the Convertible Notes did not exceed the principal value of those notes.

Capped Call Transactions

In connection with the offering of the Convertible Notes, the Company entered into privately-negotiated capped call transactions with one of the initial purchasers of the convertible notes or its affiliate and certain other financial institutions. The Company used approximately $46.0 million of the net proceeds from the offering of the Convertible Notes to pay the cost of the capped call transactions. The capped call transactions are expected generally to reduce potential dilution to the Company’s common stock upon any conversion of the Convertible Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be, in the event that the market value per share of the Company’s common stock, as measured under the terms of the capped call transactions at the time of exercise, is greater than the strike price of the capped call transactions (which initially corresponds to the initial conversion price of the Convertible Notes, and is subject to certain adjustments), with such reduction and/or offset subject to a cap initially equal to approximately $55.16 (which represents a premium of approximately 100% over the last reported sale price of the Company’s common stock on November 11, 2020), subject to certain adjustments. The capped call transactions are separate transactions, entered into by the Company and are not part of the terms of the Convertible Notes.

Given that the transactions meet certain accounting criteria, the convertible note capped call transactions are recorded in stockholders’ equity, and they are not accounted for as derivatives and are not remeasured each reporting period. As of September 30, 2022 and December 31, 2021, the Company had not purchased any shares under the convertible note capped call transactions.

Prepaid Forward

In connection with the offering of the Convertible Notes, the Company entered into a prepaid forward stock repurchase transaction (“Prepaid Forward”) with a financial institution (“Forward Counterparty”). Pursuant to the Prepaid Forward, the Company used approximately $55.0 million of the net proceeds from the offering of the Convertible Notes to fund the Prepaid Forward. The aggregate number of shares of the Company’s common stock underlying the Prepaid Forward was approximately 1,994,198. The expiration date for the Prepaid Forward is November 15, 2025, although it may be settled earlier in whole or in part. Upon settlement of the Prepaid Forward, at expiration or upon any early settlement, the Forward Counterparty will deliver to the Company the number of shares of common stock underlying the Prepaid Forward or the portion thereof being settled early. The shares purchased under the Prepaid Forward are treated as treasury stock and not outstanding for purposes of the calculation of basic and diluted earnings per share, but will remain outstanding for corporate law purposes, including for purposes of any future stockholders’ votes, until the Forward Counterparty delivers the shares underlying the Prepaid Forward to the Company. As of September 30, 2022, 71,174 shares had been delivered to the Company. The Company’s Prepaid Forward hedge transaction exposes the Company to credit risk to the extent that its counterparty may be unable to meet the terms of the transaction. The Company mitigates this risk by limiting its counterparty to a major financial institution.
