On September 19, 2025, the Company issued $201.3 million principal amount of its 3.75% convertible senior notes due September 15, 2030. The 2030 Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of September 19, 2025, between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). The 2030 Notes are the Company’s senior, unsecured obligations and bear interest at a rate of 3.75% per year payable semi-annually in arrears on March 15 and September 15 of each year, beginning on March 15, 2026. Each $1,000 principal amount of the 2030 Notes will be convertible into 86.8206 shares of the Company’s common stock, which is equivalent to a conversion price of approximately $11.52 per share, subject to adjustment upon the occurrence of specified events. In addition, if certain corporate events that constitute a “make-whole fundamental change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. The 2030 Notes are convertible at the option of the holders of the 2030 Notes before June 15, 2030, only under the following circumstances: (1) during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on December 31, 2025, if the last reported sale price per share of the Company’s common stock exceeds 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 consecutive business days immediately after any 10 consecutive trading day period (such 10 consecutive trading day period, the “measurement period”) if the trading price per $1,000 principal amount of the 2030 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 our 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 Company’s common stock; or (4) if the Company calls (or is deemed to have called) the 2030 Notes for redemption. From and after June 15, 2030, noteholders may convert their 2030 Notes at any time at their election until the close of business on the second scheduled trading day immediately before the maturity date. The Company will settle conversions by paying cash up to the aggregate principal amount of the 2030 Notes to be converted and paying or delivering, as applicable, cash, shares of its common stock or a combination of cash and shares of its common stock, at the Company’s election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the Notes being converted, based on the applicable conversion rate. The 2030 Notes will be redeemable, in whole or in part (subject to certain limitations described below), at the Company’s option at any time, and from time to time, on or after September 20, 2028 and on or before the 46th scheduled trading day immediately before the maturity date, but only if (i) the Notes are “Freely Tradable” (as defined in the Indenture) as of the date the Company sends the related redemption notice, and all accrued and unpaid additional interest, if any, has been paid in full as of the most recent interest payment date occurring on or before the date the Company sends the related redemption notice; and (ii) the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such redemption notice. However, the Company may not redeem less than all of the outstanding Notes unless at least $70.0 million aggregate principal amount of Notes are outstanding and not called for redemption as of the time the Company sends, and after giving effect to, the related redemption notice. The redemption price will be a cash amount equal to the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, calling (or the deemed calling of) any Note for redemption will constitute a “make-whole fundamental change” with respect to that Note, in which case the conversion rate applicable to the conversion of that Note will be increased in certain circumstances if it is converted during the related redemption conversion period. No sinking fund is provided for the 2030 Notes, which means the Company is not required to redeem or retire the 2030 Notes periodically. If certain corporate events that constitute a “fundamental change” (as defined in the Indenture) occur, then, subject to a limited exception for certain cash mergers, noteholders may require the Company to repurchase their Notes at a cash repurchase price equal to the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The definition of “fundamental change” includes certain business combination transactions involving the Company and certain de-listing events with respect to the Company’s common stock. Capped Calls In connection with th e pricing of the 2030 Notes and the exercise of the initial purchasers’ option to purchase additional 2030 Notes, the Company entered into privately negotiated capped call transactions with one of the initial purchasers of the 2030 Notes or its affiliate and certain other financial institutions pursuant to capped call confirmations (collectively, the “Capped Calls”). The premiums paid for the purchases of the Capped Calls were approximately $17.6 million. The Capped Calls have an initial strike price of app roximately $11.52 per share, subject to certain adjustments substantially similar to those applicable to the corresponding 2030 Notes. The Capped Calls have an initial cap price of approximately $15.51 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution adjustments, approximately 17.5 million shares of the Company’s common stock. The Capped Calls are generally expected to reduce potential dilution to the Company’s common stock and/or offset any cash payments that the Company is required to make in excess of the principal amount of any converted 2030 Notes, with such reduction and/or offset subject to a cap, based on the cap price of the Capped Calls. The Capped Calls are separate transactions and are not part of the terms of the 2030 Notes. The Capped Calls do not meet the criteria for separate accounting as a derivative as they are indexed to the Company's stock and meet the requirements to be classified in equity and, as such, are not remeasured each reporting period. The premiums paid for the Capped Calls were included as a net reduction to additional paid-in capital within stockholders’ equity during the quarter ended September 30, 2025.
