Senior Secured Credit Facilities Agreement
On February 16, 2021, the Company entered into a Senior Secured Credit Facilities Agreement (as amended by that
certain First Amendment to Credit Agreement, the “Credit Agreement”) with the lenders from time to time party thereto (the “Lenders”) and Silicon Valley Bank, a division of First-Citizens Bank & Trust Company, as administrative agent, issuing lender and swingline lender ("SVB First-Citizens"), which provides for a $100.0 million senior secured revolving credit facility, with a maturity date of February 16, 2024. Loans under the Credit Agreement bear interest at a rate per annum equal to, at the Company's option, the ABR (as defined in the Credit Agreement) or the Adjusted Term SOFR (as defined in the Credit Agreement), in each case, plus a margin based on the average daily outstanding balance of all loans and letters of credit under
the Credit Agreement and ranging from 0.75% to 1.00% in the case of loans bearing interest at ABR, and 1.75% to 2.00%, in the case of loans bearing interest at Adjusted Term SOFR. On February 16, 2024, the Company entered into the Second Amendment to Credit Agreement with the Lenders and SVB First-Citizens, which, among other things, extended the maturity date of the loans under the Credit Agreement to June 14, 2024. On April 30, 2024, the Company entered into the Third Amendment to Credit Agreement with the Lenders and SVB First-Citizens, pursuant to which, among other things, the Company (a) reduced the commitments under the Credit Agreement to $60.0 million, (b) set the interest rate for loans bearing interest at ABR at 1.00% and loans bearing interest at Adjusted Term SOFR at 2.00%, and (c) extended the maturity date under the Credit Agreement to the earliest of (i) April 30, 2027, (ii) so long as any permitted convertible debt is outstanding, on January 30, 2027, unless Net Liquidity as of January 30, 2027 is greater than or equal to $200.0 million (or, if the amount of outstanding permitted convertible debt is less than $35.0 million, $120.0 million), and (iii) so long as any permitted convertible debt is outstanding after January 30, 2027, if Net Liquidity is less than $200.0 million (or, if the amount of outstanding permitted convertible debt is less than $35.0 million, $120.0 million), on such date.
Interest payments on outstanding borrowings are due on the last day of each interest period. The Credit Agreement has a commitment fee on the unused portion of the borrowing commitment, which is payable on the last day of each calendar quarter at a rate per annum of 0.20% to 0.25% depending on the average daily outstanding balance of all loans and letters of credit under the Credit Agreement. In addition, the Company’s Credit Agreement contains a financial covenant that requires the Company to maintain a consolidated adjusted quick ratio of at least 1:25 to 1:00 tested on a quarterly basis as well as a springing revenue growth covenant for certain periods if the Company’s consolidated adjusted quick ratio falls below 1.75 to 1:00 on the last day of any fiscal quarter. The Credit Agreement requires the Company to comply with various affirmative and negative covenants, and contains customary events of default.
As of March 31, 2025, the Company was in compliance with all of the Credit Agreement’s covenants. During the three months ended March 31, 2025 and 2024, no amounts were drawn down on the Credit Agreement. As of March 31, 2025 and December 31, 2024, no amounts were outstanding under the Credit Agreement.
Convertible Senior Notes due 2026
On March 5, 2021, the Company issued approximately $948.8 million aggregate principal amount of 0% convertible senior notes due 2026 (the “2026 Notes”), including the exercise in full by the initial purchasers of their option to purchase up to an additional approximately $123.8 million principal amount of the 2026 Notes. The 2026 Notes were issued in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The 2026 Notes will mature on March 15, 2026, unless earlier converted, redeemed or repurchased. The net proceeds from the issuance of the 2026 Notes were approximately $930.0 million after deducting the initial purchasers’ discounts and transaction costs.
The Company may not redeem the 2026 Notes prior to March 20, 2024. On or after March 20, 2024, the Company may redeem for cash, all or any portion of the 2026 Notes, at the Company’s option, at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price for the 2026 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. No sinking fund is provided for the 2026 Notes.
Holders of the 2026 Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding December 15, 2025, only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (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 for the 2026 Notes on each applicable trading day; (ii) 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 indenture agreement governing the Note filed with the Company’s Current Report on Form 8-K filed with the SEC on March 5, 2021, 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 of the Company’s common stock and the conversion rate on each such trading day; (iii) if the Company calls such 2026 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the applicable redemption date, but only with respect to the 2026 Notes called (or deemed called) for redemption; or (iv) upon the occurrence of specified corporate events. On or after December 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes at any time, regardless of the foregoing circumstances.
Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, 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 initial conversion rate is 9.7272 shares of common stock per $1,000 principal amount of 2026 Notes, equivalent to an initial conversion price of approximately $102.80 per share of common stock. The conversion rate is subject to adjustment as described in the indenture governing the 2026 Notes but will not be adjusted for any accrued and unpaid special interest. In addition, following certain corporate events that occur prior to the maturity date of the 2026 Notes or if the Company delivers a notice of redemption in respect of the 2026 Notes, the Company will, in certain circumstances, increase the conversion rate of the 2026 Notes for a holder who elects to convert its 2026 Notes, in connection with such a corporate event or convert its 2026 Notes called (or deemed called) for redemption during the related redemption period, as the case may be.
The indenture includes customary covenants and sets forth certain events of default after which the 2026 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the 2026 Notes become automatically due and payable. If the Company undergoes a fundamental change, as defined in the indenture agreement governing the 2026 Notes, then subject to certain conditions and except as described in the indenture governing the 2026 Notes, holders may require the Company to repurchase for cash all or any portion of their 2026 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date.
The Company evaluated the terms of the 2026 Notes and concluded that the conversion feature does not require separation and that there were no other derivatives that required separation. As such, the Company has combined these features with the host contract and the Company accounts for the 2026 Notes as a single liability in long-term debt on its consolidated balance sheet. The initial purchasers’ discounts and transaction costs of $18.6 million incurred related to the issuance of the 2026 Notes were classified as a contra-liability and represents the difference between the principal and carrying amount of the 2026 Notes, which is amortized to interest expense using the effective interest method over the term of the 2026 Notes.
As of March 31, 2025, the conversion conditions had not been met and therefore the 2026 Notes were not yet convertible.
On May 25, 2022, the Company entered into separate, privately negotiated transactions with certain holders of the 2026 Notes to repurchase (the “Repurchases”) $235.0 million aggregate principal amount of the 2026 Notes for an aggregate cash repurchase price of $176.4 million and aggregate transaction costs of $0.7 million. The Repurchases were accounted for as a debt extinguishment that resulted in a net gain of $54.4 million, which was recorded as non-operating income on the Company's consolidated statement of operations for the year ended December 31, 2022.
During the year ended December 31, 2023, the Company entered into several separate privately negotiated transactions with certain holders of the 2026 Notes to repurchase $367.3 million aggregate principal amount of the 2026 Notes for an aggregate cash repurchase price of $309.1 million and aggregate transaction costs of $2.0 million.
During the year ended December 31, 2024, the Company entered into separate, privately negotiated transactions with certain holders of the 2026 Notes to exchange $157.9 million aggregate principal amount of the 2026 Notes for $150.0 million aggregate principal amount of 7.75% convertible senior notes due 2028 (the “2028 Notes”), which were issued in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The exchange was accounted for as a debt extinguishment and an issuance of new debt that resulted in a net gain of $1.4 million, which was recorded as non-operating income on the Company’s consolidated statement of operations for the year ended December 31, 2024.
The Company classified the 2026 Notes as current debt on the Company’s condensed consolidated balance sheet as of March 31, 2025, which is within one year of maturity of the 2026 Notes.
Convertible Senior Notes due 2028
The 2028 Notes will accrue interest at a rate of 7.75% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on June 1, 2025. The 2028 Notes will mature on June 1, 2028, unless earlier converted or repurchased. The principal amount of the 2028 Notes was $150.0 million. The Company may not redeem the 2028 Notes prior to the maturity date.

Holders of the 2028 Notes may convert their notes at their option at any time prior to the close of business on the business day immediately preceding March 1, 2028, only under the following circumstances: (i) during any calendar quarter commencing after the calendar quarter ending on March 31, 2025 (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 for the 2028 Notes on each applicable trading day; (ii) 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 indenture agreement governing the note filed with the Company’s Current Report on Form 8-K filed with the SEC on December 5, 2024, 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 of the Company’s common stock and the conversion rate on each such trading day; or (iii) upon the occurrence of specified corporate events. On or after March 1, 2028 and prior to the close of business on the scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes at any time, regardless of the foregoing circumstances.

Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, 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 initial conversion rate is 50.6568 shares of common stock per $1,000 principal amount of 2028 Notes, equivalent to an initial conversion price of approximately $19.74 per share of common stock. The conversion rate is subject to adjustment as described in the indenture governing the 2028 Notes but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date of the 2028 Notes, the Company will, in certain circumstances, increase the conversion rate of the 2028 Notes for a holder who elects to convert its 2028 Notes, in connection with such a corporate event.

The indenture includes customary covenants and sets forth certain events of default after which the 2028 Notes may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the 2028 Notes become automatically due and payable. If the Company undergoes a fundamental change, as defined in the indenture agreement governing the 2028 Notes, then subject to certain conditions and except as described in the indenture governing the 2028 Notes, holders may require the Company to repurchase for cash all or any portion of their 2028 Notes at a fundamental change repurchase price equal to 100% of the principal amount of the 2028 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date.

The Company evaluated the terms of the 2028 Notes and concluded that the conversion feature does not require separation and that there were no other derivatives that required separation. As such, the Company has combined these features with the host contract and the Company accounts for the 2028 Notes as a single liability in long-term debt on its consolidated balance sheet. The Company determined the fair value of the 2028 Notes on December 5, 2024 to be $155.7 million using a valuation technique of quoted prices in dealer markets under the market approach that resulted in a debt premium of $5.7 million. Transaction costs of $5.8 million incurred related to the issuance of the 2028 Notes, partially offset by the aforementioned premium, were recorded as contra-liability and represents the difference between the principal and the carrying amount of the 2028 Notes, which is amortized to interest expense using the effective interest method over the term of the 2028 Notes.
As of March 31, 2025, the conversion conditions had not been met and therefore the 2028 Notes were not yet convertible.
The following table reflects the carrying values of the long-term debt as of March 31, 2025 and December 31, 2024:
