Debt Disclosure [Abstract] |
Debt | 8. Debt Term Loan On January 6, 2023, the Company entered into a $150.0 million term loan credit facility with Braidwell Transaction Holdings, LLC (the “Braidwell Term Loan”). The Braidwell Term Loan provides for an initial term loan of $100.0 million which was funded on the closing date. On September 28, 2023, the Company drew an additional $50.0 million (the “delayed draw term loan(s)” or the “DDTL”). The Braidwell Term Loan matures on January 6, 2028. As of March 31, 2024, the outstanding balance under the Braidwell Term Loan was $150.0 million. In conjunction with the issuance of the Braidwell Term Loan, the Company incurred $3.4 million in debt issuance costs and $1.5 million in commitment fees. Commitment fees paid to the lender were accounted for as a debt discount. The debt issuance costs and debt discount were recorded as a direct reduction of the carrying amount of the loan on the condensed consolidated balance sheets and are being amortized over the life of the loan. As of March 31, 2024, debt issuance costs and debt discount, net of accumulated amortization, associated with the Braidwell Term Loan were $2.9 million and $1.2 million, respectively. Borrowings under the Braidwell Term Loan bear interest at a rate per annum equal to the Term Secured Overnight Financing Rate for such SOFR business day ("SOFR") subject to a 3% floor, plus 5.75%. The applicable interest rate as of March 31, 2024 was 11.2%. The loan agreement includes an undrawn commitment fee, which is calculated as 1% per annum of the average daily undrawn portion of the DDTL. Interest and undrawn commitment fees incurred are due quarterly. The Company is also required to pay fees on any prepayment of the Braidwell Term Loan, ranging from 2.0% to 1.0% depending on the date of prepayment, and a final payment fee equal to 3.25% of the principal amount of the loans drawn. The effective interest rate as of March 31, 2024 was 12.2%. During the three months ended March 31, 2024, the Company recognized interest expense on the Braidwell Term Loan of $4.4 million, which includes $0.1 million for the amortization of debt issuance costs and $0.1 million for the debt discount. During the three months ended March 31, 2023, the Company recognized interest expense on the Braidwell Term Loan of $2.8 million, which includes $0.1 million for the amortization of debt issuance costs and $0.1 million for the debt discount. Upon the Braidwell Term Loan’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Braidwell Term Loan will be due and payable. The Braidwell Term Loan is secured by substantially all of the Company’s assets with the priority interest of the lenders in the Braidwell Term Loan and the Revolving Credit Facility, as defined below, subject to terms of a customary intercreditor agreement, which provides that the lenders under the Revolving Credit Facility have a priority with respect to the Company's accounts receivable, inventory, medical instruments, and items related to the foregoing, and the lenders under the Braidwell Term Loan have priority with respect to the remainder of the Company's assets. The loan agreement contains customary representations and warranties and affirmative and negative covenants. Under the loan agreement, the Company is required to maintain a minimum level of liquidity. The loan agreement also includes certain events of default, and upon the occurrence of such events of default, all outstanding loans under the Braidwell Term Loan may be accelerated and/or the lenders’ commitments terminated. The Company is in compliance with all required financial covenants as of March 31, 2024. Revolving Credit Facility In September 2022, the Company entered into a revolving credit facility (the “Revolving Credit Facility”) with entities affiliated with MidCap Financial Trust (“MidCap”). The Revolving Credit Facility provides up to $50.0 million in borrowing capacity to the Company based on a borrowing base. The borrowing base is calculated based on certain accounts receivable and inventory assets. The Company may request increases up to $25.0 million in the Revolving Credit Facility for a total commitment of up to $75.0 million. The Company subsequently increased the borrowing capacity by $5.0 million for a total borrowing capacity of $55.0 million. The Revolving Credit Facility matures on the earlier of September 29, 2027, or 90 days prior to the final maturity date of the Company’s 2026 Notes. As of March 31, 2024, the outstanding balance under the Revolving Credit Facility was $50.0 million. In conjunction with obtaining the Revolving Credit Facility, the Company incurred $1.4 million in debt issuance costs. These costs were capitalized to other assets on the condensed consolidated balance sheets and are being amortized over the life of the Revolving Credit Facility. As of March 31, 2024, debt issuance costs, net of accumulated amortization, associated with the Revolving Credit Facility were $1.0 million. The outstanding loans under the Revolving Credit Facility bear interest at the sum of Term SOFR plus 3.5% per annum. The applicable interest rate as of March 31, 2024 was 8.9%. The loan agreements include an unused line fee, which is calculated as 0.5% per annum of either the unused Revolving Credit Facility or a minimum balance. Interest and unused line fees incurred are due and capitalized to the outstanding principal balance monthly. The Company recognized interest expense on the Revolving Credit Facility of $0.4 million and $0.3 million, which includes approximately $0.1 million and $0.1 million for the amortization of debt issuance costs, during the three months ended March 31, 2024 and 2023, respectively. Upon the Revolving Credit Facility’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Revolving Credit Facility will be due and payable. The Revolving Credit Facility contains a lockbox arrangement clause requiring the Company to maintain a lockbox bank account. If the revolving loan availability is less than 30% of the revolving loan limit for five consecutive business days, or the Company is in default, MidCap will apply funds collected from the Company's lockbox account to reduce the outstanding balance of the Revolving Credit Facility. As of March 31, 2024, the Company's loan availability level has not activated lockbox deductions, nor is it expected to for the next 12 months; therefore, the Company has determined that the outstanding balance under the Revolving Credit Facility is long-term debt on the condensed consolidated balance sheets. The Revolving Credit Facility is secured by substantially all of the Company’s assets with the priority interest of the lenders subject to terms of a customary intercreditor agreement in connection with the Braidwell Term Loan, as described above. The loan agreements and other ancillary documents contain customary representations and warranties and affirmative and negative covenants. Under the loan agreements, the Company is required to maintain a minimum level of liquidity. The loan agreements also include certain events of default, and upon the occurrence of such events of default, all outstanding loans under the Revolving Credit Facility may be accelerated and/or the lenders’ commitments terminated. The Company is in compliance with all required financial covenants as of March 31, 2024. 0.75% Convertible Senior Notes due 2026 In August 2021, the Company issued $316.3 million aggregate principal amount of unsecured 2026 Notes with a stated interest rate of 0.75% and a maturity date of August 1, 2026. Interest on the 2026 Notes is payable semi-annually in arrears on February 1 and August 1 of each year, beginning on February 1, 2022. The net proceeds from the sale of the 2026 Notes were approximately $306.2 million after deducting the initial purchasers’ offering expenses. The 2026 Notes do not contain any financial covenants. The 2026 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 54.5316 shares of the Company’s common stock per $1,000 principal amount of 2026 Notes (equivalent to an initial conversion price of approximately $18.34 per share). The conversion rate will be subject to adjustment upon the occurrence of certain specified events, including certain distributions and dividends to all or substantially all of the holders of the Company’s common stock. Based on the terms of the 2026 Notes, 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. Holders of the 2026 Notes have the right to convert their notes in certain circumstances and during specified periods. Prior to the close of business on the business day immediately preceding February 2, 2026, holders may convert all or a portion of their 2026 Notes only under the following circumstances: (1) during any calendar quarter (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 on each applicable trading day; (2) during the 5 consecutive business days immediately after any 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2026 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 (3) upon the occurrence of specified corporate events. From and after February 2, 2026, holders of the 2026 Notes 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. As of March 31, 2024, none of the conditions permitting the holders of the 2026 Notes to convert have been met. The 2026 Notes are classified as long-term debt on the condensed consolidated balances sheet as of March 31, 2024. The 2026 Notes are redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or after August 6, 2024 and on or before the 40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid interest, if any, but only if the last reported sale price per share of the Company’s common stock exceeds 130% of the conversion price for a specified period of time. In addition, calling any of the 2026 Notes for redemption will constitute a “make-whole fundamental change” with respect to the redeemable note, in which case the conversion rate applicable to the conversion of the redeemed note will be increased in certain circumstances if such note is converted after it is called for redemption. If a fundamental change occurs prior to the maturity date, holders may require the Company to repurchase all or a portion of their 2026 Notes for cash at a price equal to 100% of the principal amount of the 2026 Notes plus accrued and unpaid interest. No principal payments are otherwise due on the 2026 Notes prior to maturity. The Company recorded the full principal amount of the 2026 Notes as a long-term liability net of deferred issuance costs. The annual effective interest rate for the 2026 Notes is 1.4%. The Company recognized interest expense on the 2026 Notes of $1.1 million, which includes $0.5 million for the amortization of debt issuance costs, during the three months ended March 31, 2024 and 2023. The Company uses the if-converted method for assumed conversion of the 2026 Notes to compute the weighted-average shares of common stock outstanding for diluted earnings per share, if applicable. The outstanding principal amount and carrying value of the 2026 Notes consists of the following (in thousands):
|  | March 31, 2024 |  | December 31, 2023 |
Principal |  | $ | 316,250 |  | $ | 316,250 |
Unamortized debt issuance costs |  |  | (4,791 | ) |  | (5,293 | )
Net carrying value |  | $ | 311,459 |  | $ | 310,957 |
Capped Call Transactions In connection with the offering of the 2026 Notes, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution and/or offset the cash payments the Company is required to make in excess of the principal amount of the 2026 Notes upon conversion of the 2026 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 with such reduction and/or offset subject to a cap. The Capped Call Transactions have an initial cap price of $27.68 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 August 5, 2021, and is subject to certain adjustments under the terms of the Capped Call Transactions. Collectively, the Capped Call Transactions cover, initially, the number of shares of the Company’s common stock underlying the 2026 Notes, subject to anti-dilution adjustments substantially similar to those applicable to the 2026 Notes. The cost of the Capped Call Transactions was approximately $39.9 million. The Capped Call Transactions are separate transactions and are not part of the terms of the 2026 Notes and will not affect any holder’s rights under the notes. Holders of the 2026 Notes will not have any rights with respect to the Capped Call Transactions. Other Debt Agreements The Company has two loan agreements under French government sponsored COVID-19 relief initiatives (“PGE” loans) which mature in 2027. Monthly and quarterly installments of principal and interest under each PGE loan agreement is due until the original principal amounts and applicable interest is fully repaid in 2027. The outstanding obligation under each PGE loan as of March 31, 2024 was $2.9 million and $1.3 million at weighted average interest rates of 0.98% and 1.25%, respectively, and weighted average costs of the state guaranty of 0.69% and 1.00%, respectively. Total Indebtedness Principal payments remaining on the Company's debt are as follows as of March 31, 2024 (in thousands):
Remainder of 2024 |  | $ | 2,181 |
2025 |  |  | 1,704 |
2026 |  |  | 317,774 |
2027 |  |  | 50,629 |
