(1)Includes $4.5 million and $5.5 million of carrying amount of deferred issuance costs on the 1.75% Convertible Notes as of June 30, 2024 and December 31, 2023, respectively, and $0.7 million and $0.8 million of carrying amount of deferred issuance costs on the 4.625% Senior Notes as of June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024, $550.0 million of principal of 1.75% Convertible Notes will mature in 2026 and $460.0 million of principal of 4.625% Senior Notes will mature in 2030. 4.625% Senior Notes On October 7, 2020, the Company completed the issuance and sale of $750.0 million aggregate principal amount of its 4.625% senior notes due 2030 (the “4.625% Senior Notes”) in a private placement offering exempt from the registration requirements of the Securities Act of 1933, as amended. The Company received proceeds of $742.7 million after deducting the initial purchasers’ discounts, commissions and offering expenses. The net proceeds were used to redeem all of its then outstanding 6.0% Senior Notes due in 2025 and, the remaining net proceeds were available for general corporate purposes which may include acquisitions and the repurchase or redemption of other outstanding indebtedness. These senior notes bear interest at a rate of 4.625% per annum, payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2021. The 4.625% Senior Notes mature on October 15, 2030, and are senior unsecured obligations of the Company which are guaranteed, jointly and severally, on an unsecured basis by certain of the Company’s existing and future domestic direct and indirect wholly-owned subsidiaries (collectively, the “Guarantors”). If the Company or any of its restricted subsidiaries acquires or creates a domestic restricted subsidiary, other than an Insignificant Subsidiary (as defined in the indenture pursuant to which the 4.625% Senior Notes were issued (the “Indenture”)), after the issue date, or any Insignificant Subsidiary ceases to fit within the definition of Insignificant Subsidiary, such restricted subsidiary is required to unconditionally guarantee, jointly and severally, on an unsecured basis, the Company’s obligations under the 4.625% Senior Notes. The Company may redeem some or all of the 4.625% Senior Notes at any time on or after October 15, 2025 at specified redemption prices plus accrued and unpaid interest, if any, up to, but excluding the redemption date. In addition, at any time prior to October 15, 2025, the Company may redeem some or all of the 4.625% Senior Notes at a price equal to 100% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus an applicable “make-whole” premium. The discount and deferred issuance costs are being amortized, at an effective interest rate of 4.7%, to interest expense through the maturity date. The Indenture contains covenants that restrict the Company’s ability to (i) pay dividends or make distributions on the Company’s common stock or repurchase the Company’s capital stock; (ii) make certain restricted payments; (iii) create liens or enter into sale and leaseback transactions; (iv) enter into transactions with affiliates; (v) merge or consolidate with another company; and (vi) transfer and sell assets. These covenants contain certain exceptions. Restricted payments are applicable only if the Company and subsidiaries designated as restricted subsidiaries have a net leverage ratio of greater than 3.5 to 1.0. In addition, if such net leverage ratio is in excess of 3.5 to 1.0, the restriction on restricted payments is subject to various exceptions, including the total aggregate amount not exceeding the greater of (A) $250 million and (B) 50.0% of EBITDA for the most recently ended four fiscal quarter period ended immediately prior to such date for which internal financial statements are available. The Company is in compliance with its debt covenants for the 4.625% Senior Notes as of June 30, 2024. Cumulatively as of June 30, 2024, the Company has repurchased approximately $290 million in aggregate principal of its 4.625% Senior Notes. There were no repurchases of 4.625% Senior Notes during the three and six months ended June 30, 2024 and June 30, 2023. 1.75% Convertible Notes On November 15, 2019, the Company issued $550.0 million aggregate principal amount of 1.75% convertible senior notes due November 1, 2026 (the “1.75% Convertible Notes”). The Company received proceeds of $537.1 million in cash, net of purchasers’ discounts and commissions and other debt issuance costs. A portion of the net proceeds were used to pay off all amounts outstanding under the then-existing credit facility. The 1.75% Convertible Notes bear interest at a rate of 1.75% per annum, payable semiannually in arrears on May 1 and November 1 of each year, beginning on May 1, 2020. The 1.75% Convertible Notes will mature on November 1, 2026, unless earlier converted or repurchased. Under certain conditions set forth in the indenture, the 1.75% Convertible Notes bear additional interest of 0.50% per annum payable semiannually in arrears on May 1 and November 1 of each year, beginning on May 1, 2021. During the three and six months ended June 30, 2023, the Company recorded $7.4 million of interest expense related to the 1.75% Convertible Notes for such additional interest. The Company paid $7.0 million of this interest obligation to the trustee under the indenture for the 1.75% Convertible Notes in August 2023. The Company recorded additional interest of $0.3 million in the third quarter of 2023 and paid the remaining $0.7 million in November 2023. As of August 1, 2023, the Company has complied with the conditions set forth in the indenture. As such , the cumulative $7.7 million interest expense was non-recurring. Holders may surrender their 1.75% Convertible Notes for conversion at any time prior to the close of business on the business day immediately preceding July 1, 2026 only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on March 31, 2020 (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 the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding the calendar quarter is greater than 130% of the applicable conversion price of the 1.75% Convertible Notes on each such applicable trading day; (ii) during the five business day period following any 10 consecutive trading day period in which the trading price per $1,000 principal amount of 1.75% 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 applicable conversion rate on each such trading day; or (iii) upon the occurrence of specified corporate events. On or after July 1, 2026, and prior to the close of business on the business day immediately preceding the maturity date, holders may convert all or any portion of their notes at any time, regardless of the foregoing circumstances. The Company will settle conversions of the 1.75% Convertible Notes by paying or delivering, as the case may be, cash, shares of the Company’s common stock or a combination thereof at the Company’s election. The Company currently intends to satisfy its conversion obligation by paying and delivering a combination of cash and shares of the Company’s common stock. Holders of the notes will have the right to require the Company to repurchase for cash all or any portion of their notes upon the occurrence of certain corporate events, subject to certain conditions. As of June 30, 2024 and December 31, 2023, the market trigger conditions did not meet the conversion requirements of the 1.75% Convertible Notes and, accordingly, the 1.75% Convertible Notes are classified as long-term debt on our Condensed Consolidated Balance Sheets. As of June 30, 2024, the conversion rate is 9.3783 shares of the Company’s common stock for each $1,000 principal amount of 1.75% Convertible Notes (or 5,158,071 shares), which represents a conversion price of approximately $106.63 per share of the Company’s common stock. The conversion rate is subject to adjustment for certain events as set forth in the indenture governing the 1.75% Convertible Notes, but will not be adjusted for accrued interest. In addition, upon the occurrence of a “Make-Whole Fundamental Change” (as defined in the 1.75% Convertible Note Indenture), the Company will increase the conversion rate for a holder that elects to convert its 1.75% Convertible Notes in connection with such a corporate event in certain circumstances. The Company may not redeem the 1.75% Convertible Notes prior to November 1, 2026, and no sinking fund is provided for the 1.75% Convertible Notes. The 1.75% Convertible Notes are the Company’s general senior unsecured obligations and rank: (i) senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the 1.75% Convertible Notes; (ii) equal in right of payment to the Company’s existing and future indebtedness that is not so subordinated; (iii) effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and (iv) structurally junior to all existing and future indebtedness and other liabilities incurred by the Company’s subsidiaries. The following table provides the components of interest expense related to the 1.75% Convertible Notes (in thousands):

Contractual interest expense | $ | 2,406 |  |  | $ | 9,810 |  |  | $ | 4,812 |  |  | $ | 12,216 |
Amortization of deferred issuance costs | 473 |  |  | 463 |  |  | 943 |  |  | 929 |
Total interest expense related to 1.75% Convertible Notes | $ | 2,879 |  |  | $ | 10,273 |  |  | $ | 5,755 |  |  | $ | 13,145 |
Accounting for the 1.75% Convertible Notes In connection with the issuance of the 1.75% Convertible Notes, the Company incurred $12.9 million in deferred issuance costs, which primarily consisted of the underwriters’ discount, legal and other professional service fees. Of the total deferred issuance costs incurred, $10.1 million was attributable to the liability component and is being amortized at an effective interest rate of 5.5%, to interest expense through the maturity date. The remaining $2.8 million of the deferred issuance costs was netted with the equity component in additional paid-in capital at the issuance date. Upon adoption of ASU 2020-06 using the modified retrospective approach, the Company reclassified the $2.8 million from additional paid-in-capital to long-term liability and recorded a cumulative adjustment to retained earnings for amortization from the issuance date through January 1, 2022. Credit Agreement On April 7, 2021, the Company entered into a $100.0 million credit agreement (as amended, the “Credit Agreement”). On June 18, 2024, the Company entered into a New Lender Joinder Agreement and Eighth Amendment (the “Joinder and Amendment”) to the Credit Agreement. The Joinder and Amendment provides for, among other things, (i) an increase in the Aggregate Revolving Loan Commitment by an aggregate principal amount of $250.0 million for a total of $350.0 million, (ii) an extension of the scheduled maturity date from April 7, 2026 to the earlier of (x) June 18, 2027 or (y) under certain limited circumstances, August 2, 2026, (iii) a “credit spread adjustment” for SOFR-based borrowings of 0.10% across all interest periods, (iv) the inclusion of limited conditionality borrowing mechanics with respect to certain borrowings and (v) certain other related amendments. At the Company’s option, amounts borrowed under the Credit Agreement will bear interest at either (i) a base rate equal to the greater of (x) the Federal Funds Effective Rate (as defined in the Credit Agreement) in effect on such day plus 0.5% per annum, (y) the rate of interest per annum most recently announced by the Agent (as defined in the Credit Agreement) as its U.S. Dollar “Reference Rate”, and (z) one month Term SOFR (as defined in the Credit Agreement) plus a credit spread adjustment plus 1.00% or (ii) a rate per annum equal to Term SOFR plus a credit spread adjustment, in each case, plus an applicable margin. The applicable margin relating to any base rate loan will range from 0.50% to 1.25% and the applicable margin relating to any Term SOFR loan will range from 1.50% to 2.25%, in each case, depending on the total leverage ratio of the Company, plus a credit spread adjustment equal to 0.10%. The Company is permitted to make voluntary prepayments of the Credit Facility at any time without payment of a premium or penalty. The Credit Agreement is secured by an associated collateral agreement that provides for a lien on the majority of the Company’s assets and the assets of the guarantors, in each case, subject to customary exceptions. As of June 30, 2024, there were no amounts outstanding under the Credit Agreement. The Credit Agreement contains financial maintenance covenants, including (i) a maximum total leverage ratio as of the last date of any fiscal quarter not to exceed 4.00:1.00 for the Company and its restricted subsidiaries and (ii) a minimum interest coverage ratio as of the last date of any fiscal quarter not less than 3.00:1.00 for the Company and its restricted subsidiaries. The Credit Agreement also contains restrictive covenants that limit, among other things, the Company’s and its restricted subsidiaries’ ability to incur additional indebtedness, create, incur or assume liens, consolidate, merge, liquidate or dissolve, pay dividends or make other distributions or other restricted payments, make or hold certain investments, enter into certain transactions with affiliates, sell assets other than on terms specified by the Credit Agreement, amend the terms of certain other indebtedness and organizational documents, and change their lines of business and fiscal years, in each case, subject to customary exceptions. The Credit Agreement also sets forth customary events of default, including, among other things, the failure to make timely payments under the credit facility, the failure to satisfy certain covenants, cross-default and cross-acceleration to other material debt for borrowed money, the occurrence of a change of control, and specified events of bankruptcy and insolvency. The Company is in compliance with its debt covenants for the Credit Agreement as of June 30, 2024.
