NOTE 4. DEBT

Convertible Senior Notes

In November 2021, the Company issued, at par value, $201.3 million aggregate principal amount of 1.75% convertible senior notes due 2026 (the “Convertible Notes”). The issuance included the full exercise of an option granted by the Company to the initial purchasers of the Convertible Notes to purchase an additional $26.25 million aggregate principal amount of Convertible Notes. The Convertible Notes were issued pursuant to and are subject to the terms and conditions of an indenture, which is referred to as the Indenture, between the Company and U.S. Bank National Association, as trustee. The Convertible Notes were offered and sold in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended.

The Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 1.75% per year. Interest accrues from November 19, 2021 and is payable semi-annually in arrears on May 15 and November 15 of each year, beginning on May 15, 2022. The Convertible Notes will mature on November 15, 2026, unless earlier converted, redeemed, or repurchased in accordance with the terms of the Convertible Notes.

Holders of the Convertible Notes may convert all or any portion of their Convertible Notes at their option at any time prior to the close of business on the business day immediately preceding May 15, 2026, only under the following conditions: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2022 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, 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 after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate for the Convertible Notes on each such trading day; (3) if the Company calls such Convertible Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the applicable redemption date; or (4) upon the occurrence of specified corporate events. On or after May 15, 2026, holders may convert all or any portion of their Convertible Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date regardless of the foregoing conditions. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election.

The conversion rate for the Convertible Notes will initially be 27.2068 shares of the Company’s common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $36.76 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date or following the Company’s issuance of a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with such a corporate event or who elects to convert its Convertible Notes called (or deemed called) for redemption during the related redemption period, as the case may be.

The Company may not redeem the Convertible Notes prior to November 20, 2024. The Company may redeem for cash all or any portion of the Convertible Notes (subject to certain limitations), at its option, on or after November 20, 2024 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 notice of redemption at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Convertible Notes.

If the Company undergoes a fundamental change prior to the maturity date, subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their Convertible Notes. The fundamental change repurchase price will be equal to 100% of the principal amount of the Convertible Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

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

The net proceeds from the issuance of the Convertible Notes were approximately $194.9 million, after deducting debt issuance costs. The total debt issuance costs incurred and recorded by the Company amounted to $6.3 million, which were recorded as a reduction to the face amount of the Convertible Notes and are being amortized to interest expense using the effective interest method over the contractual term of the Convertible Notes. The Convertible Notes are recorded as a liability within convertible senior notes, non-current.

For the three and nine months ended September 30, 2022, interest expense related to the Convertible Notes and amortization of the issuance costs was $1.2 million and $3.5 million, respectively. The effective annual interest rate for the three and nine months ended September 30, 2022 was approximately 2.42%. As of September 30, 2022, the if-converted value of the Convertible Notes did not exceed the outstanding principal amount. As of September 30, 2022, the total estimated fair value of the Convertible Notes was $121.0 million, which was determined based on a market approach using actual bids and offers of the Convertible Notes in an over-the-counter market during the period. The Company considers these assumptions to be Level 2 inputs in accordance with the fair value hierarchy described in Note 6.

Capped Calls

In connection with the pricing of the Convertible Notes, with the full exercise by the initial purchasers of their option to purchase additional Convertible Notes in November 2021, the Company used approximately $18.6 million of the net proceeds from the issuance of the Convertible Notes to enter into privately negotiated capped call transactions, which are referred to as the capped calls, with various financial institutions.

The capped call transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Convertible Notes, the number of shares of the Company’s common stock underlying the Convertible Notes. The capped call transactions are expected generally to reduce the potential dilution to the Company’s common stock upon conversion of the Convertible Notes and/or offset some or all of any cash payments the Company is required to make in excess of the principal amount of converted Convertible Notes, as the case may be, in the event that the market price per share of the Company’s common stock, as measured under the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which initially corresponds to the conversion price of the Convertible Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Convertible Notes. If, however, the market price per share of the Company’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price of the capped call transactions. The initial cap price of the capped calls is $48.55 per share of common stock, which represents a premium of 75% over the last reported sale price of the Company’s common stock of $27.74 per share on November 16, 2021, and is subject to certain customary adjustments under the terms of the capped calls; provided that the cap price will not be reduced to an amount less than the strike price of $35.76 per share.

The capped call transactions are separate transactions and are not part of the terms of the Convertible Notes. The capped calls meet the criteria for classification as equity and, as such, are not remeasured each reporting period and are included as a reduction to additional paid-in-capital within stockholders’ equity.
