Debt Disclosure [Abstract] |
Debt and Financing Arrangements | Debt and Financing Arrangements 2025 Convertible Senior Notes In June 2020, the Company issued an aggregate principal amount of $287.5 million of 2025 Notes in a private offering pursuant to an Indenture dated June 25, 2020 (the “2025 Indenture”). The 2025 Notes are senior, unsecured obligations of the Company and accrue interest payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2021, at a rate of 1.25% per year. The 2025 Notes will mature on July 1, 2025, unless such notes are converted, redeemed or repurchased earlier. The 2025 Notes are convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election in the manner and subject to the terms and conditions provided in the 2025 Indenture. In October 2023, the Company provided written notice to the trustee and the note holders of the 2025 Notes that it had irrevocably elected to settle the principal amount of its convertible senior notes in cash and pay or deliver, 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, in respect to the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 2025 Notes being converted. In October 2023, the Company paid $223.7 million to repurchase $230.0 million of aggregate principal amount of the 2025 Notes with a carrying value of $227.5 million, net of unamortized issuance costs of $2.6 million. 2028 Convertible Senior Notes In October 2023, the Company issued an aggregate principal amount of $402.5 million of 2028 Notes in a private offering pursuant to an Indenture dated October 13, 2023 (the “2028 Indenture” and, together with the 2025 Indenture, the “Indentures”). The total net proceeds from the debt offering, after deducting initial purchasers’ discounts and debt issuance costs of $12.0 million, paid or payable by the Company were $390.8 million. The 2028 Notes are senior, unsecured obligations of the Company and accrue interest payable semiannually in arrears on April 15 and October 15 of each year, beginning on April 15, 2024, at a rate of 1.50% per year. The 2028 Notes will mature on October 15, 2028, unless such notes are converted, redeemed or repurchased earlier. Upon conversion, the Company will pay cash up to the aggregate principal amount of the 2028 Notes to be converted and pay or deliver, 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, in respect to the remainder, if any, of the Company’s conversion obligation in excess of the aggregate principal amount of the 2028 Notes being converted, in the manner and subject to the terms and conditions provided in the 2028 Indenture. Additional Terms of the Notes Holders of the Notes may convert all or any portion of their Notes at their option at any time prior to the close of business on April 1, 2025, with respect to the 2025 Notes, or June 15, 2028, with respect to the 2028 Notes, only under the following circumstances: •During any fiscal quarter commencing after the fiscal quarter ended October 31, 2020, with respect to the 2025 Notes, or the fiscal quarter ended January 31, 2024, with respect to the 2028 Notes (and only during such fiscal 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 fiscal quarter is greater than or equal to 130% of the relevant conversion price on each applicable trading day; •During the five business day period after any ten consecutive trading day period (the measurement period) in which the “trading price” (as defined in the relevant Indenture) per $1,000 principal amount of such 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 relevant conversion rate on each such trading day; •If the Company calls such Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or •Upon the occurrence of specified corporate events, as noted in the Indenture. On or after April 1, 2025, with respect to the 2025 Notes, or June 15, 2028, with respect to the 2028 Notes, until the close of business on the second scheduled trading day immediately preceding the relevant maturity date, holders of the Notes may convert all or any portion of their Notes at any time, regardless of the foregoing circumstances. The initial conversion rate for the 2025 Notes is 24.95 shares of common stock per $1,000 principal amount of 2025 Notes, which is equivalent to an initial conversion price of approximately $40.08 per share of common stock. The initial conversion rate for the 2028 Notes is 36.56 shares of common stock per $1,000 principal amount of 2028 Notes, which is equivalent to an initial conversion price of approximately $27.35 per share of common stock. The conversion rate for the Notes is subject to adjustment under certain circumstances in accordance with the terms of the relevant Indenture, but will not be adjusted for accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date, or if the Company delivers 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 convert its notes called (or deemed called) for redemption during the related redemption period (as defined in the relevant Indenture), as the case may be. The Company may not redeem the 2028 Notes prior to October 20, 2026. The Company may redeem for cash all or any portion of the Notes, at its option, with respect to the 2025 Notes, on a redemption date occurring on or after July 6, 2023 and prior to the 41st scheduled trading day immediately preceding the maturity date of the 2025 Notes, or with respect to the 2028 Notes, on a redemption date occurring on or after October 20, 2026 and prior to the 61st scheduled trading day immediately preceding the maturity date of the 2028 Notes, if the last reported sale price of the common stock has been at least 130% of the relevant conversion price for the Notes 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 to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the 2025 Notes or the 2028 Notes. If the Company undergoes a fundamental change (as defined in the relevant Indenture), holders may require the Company to repurchase 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 any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. The Indentures governing the Notes contain customary terms and covenants, including that upon certain events of default occurring and continuing, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding 2025 Notes or 2028 Notes may declare the entire principal of all such 2025 Notes or 2028 Notes plus accrued and unpaid interest to be immediately due and payable. Accounting for the Notes The Company early adopted ASU 2020-06 “Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” as of February 1, 2021 using the modified retrospective approach. As a result, the Notes are accounted for as a single liability measured at their amortized cost, as no other embedded features require bifurcation and recognition as derivatives. The Notes are classified as long-term liabilities as of April 30, 2024. Issuance costs are being amortized to interest expense over the contractual term of the Notes at an effective interest rate of 2.13% for the 2028 Notes and 1.91% for the 2025 Notes. The net carrying amount of the Notes as of April 30, 2024 and as of January 31, 2024 was as follows:
|  |  | As of April 30, 2024
|  |  | (in thousands)

Capped Call Transactions In connection with the offering of the 2025 Notes, the Company entered into privately negotiated capped call transactions (the “2025 Capped Calls”) with certain financial institution counterparties and in connection with the offering of the 2028 Notes, the Company entered into separate privately negotiated capped call transactions (the “2028 Capped Calls” and, together with the 2025 Capped Calls, the “Capped Calls”). The Capped Calls are generally intended to reduce or offset the potential dilution to the common stock upon any conversion of the 2025 Notes or the 2028 Notes, as applicable, with such reduction or offset, as the case may be, subject to a cap based on the cap price of such Capped Calls. For accounting purposes, the Capped Calls are separate transactions, and not part of the terms of the 2025 Notes or the 2028 Notes, as applicable. The Capped Calls are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $35.7 million incurred to purchase the 2025 Capped Calls and the cost of $55.1 million incurred to purchase the 2028 Capped Calls were each recorded as a reduction to additional paid-in capital in the accompanying condensed consolidated balance sheets. The Capped Calls will not be remeasured as long as they continue to meet the conditions for equity classification. The 2025 Capped Calls each have an initial strike price of approximately $40.08 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2025 Notes. The 2025 Capped Calls have an initial cap price of $61.66 per share, subject to certain adjustments. The 2025 Capped Calls cover, subject to anti-dilution adjustments, approximately 7.2 million shares of our common stock. The 2025 Capped Calls are subject to automatic exercise over a 40 trading day period commencing on May 2, 2025, subject to earlier termination under certain circumstances and may be settled in cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election. The 2025 Capped Calls remain outstanding as of April 30, 2024. The 2028 Capped Calls each have an initial strike price of approximately $27.35 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2028 Notes. The 2028 Capped Calls have an initial cap price of $42.90 per share, subject to certain adjustments. The 2028 Capped Calls cover, subject to anti-dilution adjustments, approximately 14.7 million shares of our common stock. The 2028 Capped Calls are subject to automatic exercise over a 60 trading day period commencing on July 20, 2028, subject to earlier termination under certain circumstances and may be settled in cash, shares of common stock or a combination of cash and shares of common stock, at the Company’s election.
