2024 Convertible Senior Notes
On April 1, 2024, we issued $172.5 million principal amount of our 2024 Convertible Senior Notes in a private offering, including the exercise in full of the initial purchasers' option to purchase up to an additional $22.5 million principal amount of the 2024 Convertible Senior Notes. The net proceeds from this offering were $166.8 million, after deducting the initial purchasers' discounts, commissions and the offering expense payable by us. The 2024 Convertible Senior Notes were issued pursuant to, and are governed by, an indenture, dated as of April 1, 2024 ( the "2024 Indenture"), between us and U.S. Bank Trust Company, National Association, as Trustee.
The 2024 Convertible Senior Notes will accrue interest at a rate of 4.25% per annum, payable semi-annually in arrears on April 1 and October 1 of each year, beginning on October 1, 2024. The 2024 Convertible Senior Notes will mature on April 1, 2029, unless earlier converted or repurchased by us. Before January 2, 2029, noteholders will have the right to convert their 2024 Convertible Senior Notes only in the following circumstances: (i) during any calendar quarter (and only during such calendar quarter) commencing after the calendar quarter ending on June 30, 2024, if the last reported sale price per share of our 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; (ii) 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 2024 Convertible Senior 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 the common stock on such trading day and the conversion rate on such trading day; (iii) upon the occurrence of certain corporate events or distributions on the common stock, as described in the 2024 Indenture; and (iv) at any time from, and including, January 2, 2029 until the close of business on the scheduled trading day immediately before the maturity date. We will settle conversions by paying or delivering, as applicable, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. The initial conversion rate is 55.4939 shares of common stock per $1,000 principal amount of 2024 Convertible Senior Notes, which represents an initial conversion price of $18.02 per share of common stock. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a "Make-Whole Fundamental Change" (as defined in the 2024 Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.
If a "Fundamental Change" (as defined in the 2024 Indenture) occurs, then, subject to a limited exception for certain cash mergers, noteholders may require us to repurchase their 2024 Convertible Senior Notes at a cash repurchase price equal to the principal amount of the 2024 Convertible Senior 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 us and certain de-listing events with respect to the common stock.

Capped Call Transactions
In connection with the issuance of the 2020 Convertible Senior Notes, we entered into privately negotiated capped call transactions (the "Capped Calls") with an affiliate of one of the initial purchasers or the 2020 Convertible Senior Notes and certain other financial institutions. The Capped Calls are recorded in stockholders' equity and were not accounted for as derivatives.
The Capped Calls each had an initial strike price of $85.14 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2020 Convertible Senior Notes. The Capped Calls had an initial cap price of $128.51 per share, subject to certain adjustments.

Cash proceeds from the termination of the Capped Calls totaled $0.1 million, which we received on June 3, 2024. The $0.1 million cash proceeds from the termination of the Capped Calls were recorded as a credit to additional paid in capital on our consolidated balance sheet.
2018 Loan Facility
In April 2022, we amended our loan facility with Pacific Western Bank (the "2018 Loan Facility") to increase the capacity of our asset-backed revolving line of credit (the "2018 Line of Credit") from $50.0 million to $60.0 million with an option to increase to $75.0 million upon syndication. Additionally with this amendment, the former cash covenant, as described below, was removed and was replaced with a requirement to maintain a minimum level of Adjusted Contribution and a minimum adjusted cash of $25.0 million, which is reduced by eligible accounts receivable in excess of the loan capacity. In November 2022, we amended our 2018 Loan Facility to modify the eligible account receivable to exclude U.K. accounts, reduce the ability to borrow up to 85% of the amount of our eligible accounts receivable to 50% and adjusted the required minimum level of Adjusted Contribution. In February 2023, we amended our 2018 Loan Facility to remove and replace the former Adjusted Contribution covenant with a requirement to maintain a minimum level of Adjusted EBITDA. In May 2023, we amended our 2018 Loan Facility to modify the covenants related to the maximum amount of cash we are allowed to pay for the First Anniversary Payment Amount and Second Anniversary Payment Amount under the Merger Agreement. In February 2024, we amended our 2018 Loan Facility to increase the ability to borrow up to 75% of the amount of our eligible accounts receivable, adjusted the required minimum level of Adjusted EBITDA and increased the interest rate to the prime rate plus 0.25%.
The 2018 Loan Facility includes customary representations, warranties and covenants (affirmative and negative), including restrictive covenants that prohibit mergers, acquisitions, dispositions of assets, incurrence of indebtedness, encumbrances on our assets and the payment or declaration of dividends, in each case subject to specified exceptions.
The 2018 Loan Facility also includes standard events of default, including in the event of a material adverse change. Upon the occurrence of an event of default, the lender may declare all outstanding obligations immediately due and payable and take such other actions as are set forth in the 2018 Loan Facility and increase the interest rate otherwise applicable to advances under the 2018 Line of Credit by an additional 3.00%. All of our obligations under the 2018 Loan Facility are secured by a first priority lien on substantially all of our assets. The 2018 Loan Facility does not include any prepayment penalties.
In April 2024, we repaid in full $30.0 million of the principal balance of the 2018 Line of Credit. Interest on advances under the 2018 Line of Credit bore an interest rate equal to the prime rate plus 0.25%. In addition, we were required to pay an unused line fee of 0.15% per annum on the average daily unused amount of the revolving commitment.
In July 2024, we amended our 2018 Loan Facility, which increased the ability to borrow up to 85% of the amount of our U.S. eligible accounts receivable and 30% of the amount of our U.K. eligible accounts receivable, decreased our required minimum level of Adjusted EBITDA, and decreased the interest rate to prime rate plus 0.125%. The amendment also established a reserve and included an extension of the maturity date of the loan to July 31, 2026.
In September 2024, we entered into an amended and restated Loan and Security Agreement, which amended and restated the original Loan and Security Agreement to consolidate the original agreement and all subsequent amendments thereto into a single document. In January 2025, we amended our 2018 Loan Facility to decrease our required minimum level of Adjusted EBITDA. In April 2025, we amended our 2018 Loan Facility to extend the maturity date of the loan to April 15, 2028.
As of December 31, 2025, we had net borrowings of $40.1 million under the 2018 Line of Credit, which includes total draw downs of $56.0 million and repayments totaling $15.9 million during the year ended December 31, 2025. Subsequent to December 31, 2025, we repaid $10.0 million on February 25, 2026 under the 2018 Line of Credit.
During the years ended December 31, 2025 and 2024, we incurred $1.5 million and $0.7 million of interest expense associated with the 2018 Loan Facility, respectively. As of December 31, 2025, we had $8.5 million of unused available borrowings under our 2018 Line of Credit. We believe we are in compliance with all financial covenants as of December 31, 2025.
