Debt Instruments
Senior Secured Credit Facilities Credit Agreement
On February 16, 2021, the Company entered into a Senior Secured Credit Facilities Credit Agreement (as amended, restated, amended and restated, supplemented, restructured, or otherwise modified from time to time, 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 a lender and as administrative agent and collateral agent for the Lenders. The Credit Agreement provides for a $60.0 million senior secured revolving facility, with a maturity date of the earlier of (i) April 30, 2027 and (ii) so long as any of our permitted convertible debt is outstanding after January 30, 2027 and 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), such date. The Company recorded $0.6 million of debt issuance costs associated with the Credit Agreement in other assets on the Company’s consolidated balance sheet.
The revolving loans bear interest, at the Company’s election, at an annual rate based on the ABR (as defined in the Credit Agreement) plus 1.00% (such loans, the “ABR Loans”) or the Adjusted Term SOFR (as defined in the Credit Agreement) plus 2.00% (such loans, the “SOFR Loans”).
Interest payments on outstanding borrowings are due, with respect to SOFR Loans, on the last day of each interest period and with respect to ABR Loans, on the last calendar day of each month. 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 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 not to be less than 5% on a quarterly basis 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 December 31, 2025 and 2024, the Company and its subsidiaries were in compliance with all of the Credit Agreement’s covenants. During the years ended December 31, 2025 and 2024, no amounts were drawn down on the Company’s Credit Agreement. As of the years ended December 31, 2025 and 2024, no amounts were outstanding under the Credit Agreement.
Convertible Senior Notes
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.

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.
During the year ended December 31, 2025, the Company issued $180.0 million aggregate principal amount of 0% convertible senior unsecured notes due in 2030 (the “2030 Notes”) in a private offering to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act. Concurrently with issuance of the 2030 Notes, the Company also entered into separate, privately negotiated transactions with certain holders of the 2026 Notes to repurchase $150.0 million aggregate principal amount of the 2026 Notes for an aggregate cash repurchase price of $148.9 million.

During any calendar quarter commencing after the calendar quarter ended June 30, 2021 for the 2026 Notes, March 31, 2025 for the 2028 Notes and March 31, 2026 for the 2030 Notes (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 calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;
During the five business day period after any five consecutive trading day period in which the trading price per $1,000 principal amount of the respective 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
Upon the occurrence of specified corporate events.
On or after the respective conversion date, as noted in the table below, holders may convert all or any portion of their respective Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date.

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.

(1) The conversion rate for the Notes is established as a number of shares of the Company's common stock per $1,000 principal amount of the Notes, that is equivalent to the conversion price per share, subject to adjustments in certain events. Upon the occurrence of certain corporate events the Company will increase the conversion rate for a holder that elects to convert its Notes.
As of December 31, 2025, the conversion conditions had not been met by any of the Notes, and therefore were not yet convertible.

As of December 31, 2025 and 2024, the total estimated fair value of the Company's convertible senior notes were $379.5 million and $327.7 million, respectively.
Capped Calls
In connection with the pricing of the issuance of the 2030 Notes, the Company entered into the Capped Calls. The Capped Calls associated with the 2030 Notes each had an initial strike price of approximately $15.26 per share. These Capped Calls had initial cap prices of $23.04 per share, subject to certain adjustments. The Capped Calls are expected to partially offset the potential dilution to the Company’s common stock upon any conversion of the 2030 Notes, with such offset subject to a cap based on the cap price. The Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offers and the announcement of such events. In addition, the Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, increased cost of hedging and hedging disruptions. For accounting purposes, the Capped Calls are separate transactions and not part of the terms of the 2030 Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders' equity resulting in a $18.2 million decrease in additional paid in capital.

About Debt Disclosures

Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.

Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
