Debt Disclosure [Abstract] |
Term loan | Debt In November 2020, the Company entered into a term loan facility of up to $30.0 million (the “SVB Term Loan”), consisting of advances of $5.0 million funded at closing and $10.0 million and $15.0 million contingent upon achievement of certain clinical development milestones and other specified conditions. On October 14, 2022 (the “2022 Effective Date”), the Company entered into a loan and security agreement with Oxford Finance Luxembourg S.À R.L. for an aggregate amount of up to $150.0 million (the “Oxford Term Loan”). The Oxford Term Loan provided for an initial term loan advance in an aggregate amount of $10.0 million funded on the 2022 Effective Date (the “Oxford Term A Loan”), and up to four additional term loan advances in an aggregate amount of $140.0 million, contingent upon the achievement of certain clinical and regulatory development milestones as well as other specified conditions. The proceeds from the Oxford Term Loan were used for general corporate and working capital purposes, and a portion of the proceeds of the Oxford Term A Loan were used to repay in full the existing outstanding indebtedness owed under the SVB Term Loan. On March 24, 2023, the Company received $10.0 million under the second term loan advance (the “Oxford Term B Loan”). On December 27, 2023 (the “2023 Effective Date”), the Company entered into a term loan facility of up to $400.0 million (the “2023 Term Loan” or “Loan Agreement”), consisting of a term loan advance in an aggregate amount of $50.0 million funded on the 2023 Effective Date (the “Term A Loan”) and four additional term loan advances subject to certain terms and conditions, as discussed below, in the amounts of $100.0 million (the “Term B Loan”), $75.0 million (the “Term C Loan”), $75.0 million (the “Term D Loan”) and $100.0 million (the “Term E Loan”). The 2023 Term Loan was entered into with Oxford Finance LLC, a Delaware limited liability company (“Oxford”), as collateral agent, and certain funds managed by Oxford and Hercules Capital, Inc. party thereto (collectively, the “Lenders”). The net proceeds of the 2023 Term Loan will be used for general corporate and working capital purposes. The Company received net proceeds from the Term A Loan of $28.4 million which primarily consisted of the Term A Loan proceeds of $50.0 million partially offset by the repayment, in full, of the existing outstanding indebtedness owed by the Company under the Oxford Term Loan of $20.0 million, lender and third-party fees related to the Loan Agreement of $1.4 million and interest amounts of $0.2 million. Based upon the Company’s accounting evaluation of the Loan Agreement, as well as the Oxford entities involved and terms of both the 2023 Term Loan and the Oxford Term Loan, the Company has applied modification accounting to the portion of the Term A Loan associated with Oxford. As such, no gain or loss is recorded upon the modification with the unamortized debt issuance costs at the 2023 Effective Date from the Oxford Term Loans included as amounts the outstanding amount under the 2023 Term Loan. Additionally, certain fees included in the net proceeds were expensed based on the applicable guidance und er ASC 470. The portion of the Term A Loan associated with Hercules Capital, Inc. has been accounted for as the issuance of new debt with the applicable accounting applied under ASC 470. The Term B Loan will be available, subject to customary terms and conditions, during the period commencing on the date the Company receives approval from the United States Food and Drug Administration for its New Drug Application for ensifentrine through and including the earliest of (i) the date that is 30 days immediately following the date the Company receives such approval and (ii) September 15, 2024. The Term C Loan will be available, subject to customary terms and conditions (including the prior borrowing of the Term B Loan), during the period commencing on the later of (i) September 15, 2025 and (ii) prior to September 30, 2025, the achievement by the Company of a specified net sales milestone. The Term D Loan will be available, subject to customary terms and conditions (including the prior borrowing of the Term C Loan), during the period commencing on the later of (i) February 15, 2026 and (ii) prior to March 31, 2026, the achievement by the Company of a specified net sales milestone. The Term E Loan will be available, subject to customary terms and conditions (including the prior borrowing of the Term D Loan) prior to June 1, 2028 at the Lenders sole discretion and upon the Company’s request. The 2023 Term Loan will mature on December 1, 2028. Each advance under the Loan Agreement accrues interest at a floating per annum rate (the “Basic Rate”) equal to (a) the greater of (i) the 1-Month CME Term SOFR (as defined in the Loan Agreement) reference rate on the last business day of the month that immediately precedes the month in which the interest will accrue and (ii) 5.34%, plus (b) 5.85%. Notwithstanding the foregoing, (i) in no event shall the Basic Rate (x) for the Term A Loan be less than 11.19% and (y) for each other 2023 Term Loan be less than the Basic Rate on the business day immediately prior to the funding date of such 2023 Term Loan, (ii) the Basic Rate for the Term A Loan for the period from the Effective Date through and including December 31, 2023 was 11.19% and (iii) the Basic Rate for each 2023 Term Loan shall not increase by more than 2.00% above the applicable Basic Rate as of the funding date of each such 2023 Term Loan. The 2023 Term Loan provides for interest-only payments on a monthly basis until the payment date immediately preceding June 1, 2028. Thereafter, amortization payments will be payable monthly in equal installments of principal plus monthly payments of accrued interest. Upon repayment (whether at maturity, upon acceleration or by prepayment or otherwise), the Borrower shall make a final payment to the Lenders in the amount of 2.50% to 3.50% of the aggregate 2023 Term Loan advanced, depending on when a 2023 Term Loan is repaid (the “Final Payment”). The Borrower may prepay the 2023 Term Loan in full or in part provided that the Borrower (i) provides ten (10) days’ prior written notice to Oxford and the Lenders, (ii) pays on the date of such prepayment (A) all outstanding principal plus accrued and unpaid interest, (B) a prepayment fee of 2.00% of the 2023 Term Loan advanced if paid on or before December 27, 2025; 1.50% of the 2023 Term Loan advanced if paid after December 27, 2025 and before December 27, 2026; 1.00% of the 2023 Term Loan advanced if paid after December 27, 2026, (C) the Final Payment and (D) all other sums, if any, that shall become due and payable under the Loan Agreement, including interest at the default rate with respect to any past due amounts. Amounts outstanding during an event of default are payable upon the Required Lenders’ (as defined in the Loan Agreement) demand and shall accrue interest at an additional rate of 5.00% per annum and (iii) any partial prepayment of the 2023 Term Loans shall be in a denomination that is a whole number multiple of $5.0 million. The 2023 Term Loan is secured by a lien on substantially all of the assets of the Company, other than intellectual property, provided that a lien on intellectual property will be granted on the earlier of (i) the funding date of any 2023 Term Loan that would cause the aggregate principal amount of outstanding 2023 Term Loan drawn pursuant to the Loan Agreement to exceed $50.0 million and (ii) prior to the Borrower or the Company entering into a Permitted Royalty Financing (as defined in the Loan Agreement). The Company has also granted Oxford and the Lenders a negative pledge with respect to its intellectual property. The Loan Agreement contains customary representations and warranties, covenants and events of default, including two financial covenants: (i) commencing on July 1, 2025, the Borrower is required to maintain certain levels of cash in the United States subject to control agreements in favor of Oxford; provided that such liquidity covenant shall not apply at any given time if the market capitalization of the Company at such time is at least $3.0 billion and (ii) commencing on September 30, 2025, the Borrower and the Company are required to maintain quarterly trailing six-month net product revenue from the sale of ensifentrine; provided that such revenue covenant will be waived at any time (x) the Borrower and the Company’s unrestricted cash balance on the last calendar day of each month during such quarter is equal to or greater than the product of 1.25 multiplied by the aggregate principal amount of outstanding 2023 Term Loan on such date, (y)(1) the Borrower and the Company’s unrestricted cash balance on the last calendar day of each month during such quarter is equal to or greater than the product of 0.5 multiplied by the aggregate principal amount of outstanding 2023 Term Loan on such date and (2) the average of the daily VWAP of the Company’s American Depositary Shares for each of the five trading days preceding the last trading day of each month during such quarter multiplied by the total number of issued and outstanding American Depositary Shares of the Company is at least $1.5 billion, or (z) the average of the daily VWAP of the Company’s American Depositary Shares for each of the five trading days preceding the last trading day of each month during such quarter multiplied by the total number of issued and outstanding American Depositary Shares of the Company is at least $3.0 billion. The Loan Agreement also contains other customary provisions, such as expense reimbursement, as well as indemnification rights for the benefit of Oxford and the Lenders. As of December 31, 2023 the interest rate was approximately 11% per annum and there was no material difference between the carrying value and the estimated fair value of the 2023 Term Loan.
