LOAN AGREEMENTS
Indenture and Notes
On February 6, 2024, the Company issued $355,000 aggregate principal amount of its 4.250% Convertible Senior Notes due 2029 (the “Notes”). The Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of February 6, 2024, between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”).
The Notes are the Company’s senior, unsecured obligations and are (i) equal in right of payment with the Company’s existing and future senior, unsecured indebtedness; (ii) senior in right of payment to the Company’s future indebtedness that is expressly subordinated to the Notes in right of payment; (iii) effectively subordinated to the Company’s existing and future secured indebtedness, including borrowings under its equipment financing agreement, to the extent of the value of the collateral securing that indebtedness; and (iv) structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent the Company is not a holder thereof) preferred equity, if any, of the Company’s subsidiaries.
The Notes accrue interest at a rate of 4.250% per annum, payable semi-annually in arrears on February 1 and August 1 of each year, beginning on August 1, 2024. The Notes mature on February 1, 2029, unless earlier converted, redeemed or repurchased. Before November 1, 2028, noteholders have the right to convert their Notes only during the following circumstances: (i) during any calendar quarter (and only during such calendar quarter) if the last reported sale price 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 a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter, (ii) during the five consecutive business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1 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 applicable conversion rate on each such trading day, (iii) upon the occurrence of certain corporate events or distributions specified in the Indenture or (iv) if the Company calls such Notes for redemption. From and after November 1, 2028, noteholders may convert their 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 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. The initial conversion rate is 195.1029 shares of common stock per $1 principal amount of Notes, which represents an initial conversion price of approximately $5.13 per share of common stock. The conversion rate and conversion price are 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 Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. As of December 31, 2025, the holder of the Notes have the right to convert between January 1, 2026 and March 31, 2026 because the Company’s common stock price exceeded the applicable conversion price by 130% for the specified period of time during the quarter ended December 31, 2025.
When a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. During the year ended December 31, 2025, the Company received conversion notices for $199,346 aggregate principal amount of Notes. These conversions resulted in the issuance of 38,892,968 shares of common stock in accordance with the terms of the Indenture governing the Notes. As of December 31, 2025, the Company cannot be required to settle the Notes in cash and has the intent and ability to settle in common stock, therefore, the Notes were classified as non-current liabilities on the Company’s consolidated balance sheet.
As of December 31, 2025, there was $155,654 outstanding under the Notes, before unamortized discount and debt issuance costs of $3,259. As of December 31, 2025, the effective interest rate under the Notes was 5.0%.
Capped Call Transactions
In connection with the pricing of the Notes, on February 1, 2024 and February 2, 2024, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain financial institutions. Collectively, the Capped Call Transactions cover, subject to customary adjustments, the number of shares of common stock initially underlying the Notes. The cost of the Capped Call Transactions was $43,168. The Capped Call Transactions are expected generally to reduce or offset the potential dilution to the Company’s common stock upon exercise of the Notes and/or the Company’s election to offset the cash payments the Company is required to make in excess of the principal amount of the Notes upon conversion of the Notes in the event that the market price per share of the Company’s common stock is greater than the strike price of the Capped Call Transactions (which initially corresponds to the initial conversion price of the Notes and is subject to certain adjustments under the terms of the Capped Call Transactions), with such reduction and/or offset subject to a cap based on the cap price of the Capped Call Transactions. The Capped Call Transactions have an initial cap price of $8.04 per share of the Company’s common stock, which represents a premium of 100% over the last reported sale price of the Company's common stock on February 1, 2024.
The Capped Call Transactions do not meet the criteria for separate accounting as a derivative as they are indexed to the Company’s stock. The premiums paid for the Capped Call Transactions have been included as a net reduction to additional paid-in capital within shareholders’ equity.
Trinity Master Equipment Financing Agreement
On December 29, 2023 (the “Effective Date”), the Company and certain of its subsidiaries (the “Subsidiaries”, together with the Company, the “Borrowers”), entered into a Master Equipment Financing Agreement (the “Trinity Loan Agreement”) with Trinity Capital, Inc., a Maryland corporation (the “Lender”) to provide financing for certain equipment and other property (the “Equipment”). The Trinity Loan Agreement provides that the Lender shall provide equipment financing in the aggregate of up to $120,000 (the “Conditional Commitment”), with advances (“Draws”) to be made as follows: (i) $70,000 on the Effective Date (the “Effective Date Draw”); and (ii) $40,000 to be drawn on the Effective Date (the “Blanket Lien Draw”), with each of the Effective Date Draw and Blanket Lien Draw payable over sixty (60) months beginning January 2024, with the final payments due in January 2029. After the Blanket Lien Draw was repaid in full, Borrowers were able to make Draws as follows: (x) $30,000 to be drawn in not more than three advances of at least $10,000 each at the Borrowers’ option no later than the date that is 18 months after the Effective Date; and (y) $20,000 to be drawn at Borrower’s option between January 1, 2025 and June 30, 2025, subject to customary conditions.
The monthly payment factors under the Trinity Loan Agreement and Blanket Lien Draw had a term of sixty (60) months and a rate factor of 0.022266. In connection with the Loan Agreement, the Company issued warrants to Lender to acquire 728,835 shares of the Company’s common stock at an exercise price of $4.87 per share (see Note 13). The proceeds from the Loan Agreement were allocated to the loan and warrants based on the relative fair value at inception, resulting in a reduction to the loan amount and amortized to interest expense over the term of the loan.
On February 8, 2024, the Company paid off all obligations under the Blanket Lien Draw in the amount of $38,778, which includes principal, unpaid interest and legal fees, resulting in a loss on extinguishment of debt of $1,330 for the year ended December 31, 2024, included in other income, net in the consolidated statements of operations and comprehensive loss.
On March 20, 2025, the Company made a draw of $25,000 under the Trinity Loan Agreement (the “March 2025 Draw”). This March 2025 Draw has a term of sixty (60) months and a rate factor of 0.022266.
On December 15, 2025, the Company paid off all obligations under the Trinity Loan Agreement in the amount of $69,120, which includes principal, prepayment fees, end of term and other fees and unpaid interest, resulting in a loss on extinguishment of debt of $5,926 for the year ended December 31, 2025. As a result, the Trinity Loan Agreement was terminated.
Hercules Capital Secured Term Loan
On June 10, 2021, the Company entered into a $100,000 secured term loan agreement with Hercules Capital, Inc. (the “Hercules Capital Secured Term Loan”) and borrowed the full amount under the secured term loan agreement. The term loan had a maturity date of June 1, 2024 and was secured by substantially all of the assets of the Company. Payments due for the term loan were interest-only until the maturity date with interest payable monthly in arrears. The outstanding principal bore (i) cash interest at the greater of (a) 8.15% or (b) 8.15% plus the prime rate minus 3.25% and (ii) payment-in-kind interest of 1.25% which was accrued and added to the outstanding principal balance. Prepayment of the outstanding principal was permitted under the loan agreement and subject to certain prepayment fees. On June 10, 2021, in connection with the secured term loan, the Company paid an initial facility charge of $1,000. On December 29, 2023, the Company was required to pay an end of term charge of $3,250 upon repayment of the loan.
On December 29, 2023, a portion of the proceeds from the Effective Date Draw and the Blanket Lien Draw were used to pay off all obligations owing pursuant to the Hercules Capital Secured Term Loan, resulting in a loss on extinguishment of debt of $1,732 for the year ended December 31, 2023. As a result, the Hercules Capital Secured Term Loan was terminated.

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.
