Debt Disclosure [Abstract] |
Convertible Debt | 6. CONVERTIBLE DEBT Convertible Debt In May 2023, we entered into a contingent convertible debt agreement, or Debt Agreement, with Silicon Valley Bank, or SVB, and SVB Innovation Credit Fund VIII, L.P., or, together with SVB, the Lenders, pursuant to which the Lenders provided term loans having an aggregate original principal amount of $16.6 million, or the Convertible Term Loan. In July 2024, we entered into a contingent convertible debt agreement, or New Debt Agreement, with Silicon Valley Bank, or SVB, a division of First-Citizens Bank & Trust Company, or FCB, in its capacity as administrative agent and collateral agent, and FCB, as a lender, or Lender, pursuant to which the Lender provided term loans having an aggregate original principal amount of $10.0 million, with additional term loans of up to $10.0 million available upon the occurrence of certain events as provided for in the New Debt Agreement and further described below, or New Convertible Term Loan. Our obligations under the New Debt Agreement are secured by substantially all of our assets, other than intellectual property. The New Debt Agreement refinanced the Debt Agreement. Our obligations under the Debt Agreement and Convertible Term Loan were satisfied in full and the Debt Agreement and Convertible Term Loan were terminated in connection with the entrance into the New Debt Agreement and New Convertible Term Loan. The New Convertible Term Loan matures on December 1, 2027, which maturity date may be extended to June 1, 2028 upon the occurrence of certain events as provided for in the New Debt Agreement. The first tranche of the New Convertible Term Loan, which was advanced on July 25, 2024, has an aggregate original principal amount of $10.0 million. The Lender will further make available to us, upon our request: (a) on or prior to October 31, 2025, a second tranche of the New Convertible Term Loan having an aggregate principal amount of $5.0 million in the event that we receive written notice that the FDA has accepted for filing our NDA with respect to cytisinicline for a smoking cessation indication, or the Additional Term Loan Event I, and (b) on or prior to December 31, 2025, a third tranche of the New Convertible Term Loan having an aggregate principal amount of $5.0 million, subject to the Lender’s sole discretion. Interest is calculated on the outstanding principal amount of the New Convertible Term Loan at a floating rate per annum equal to the greater of (i) 7.0% and (ii) the prime rate minus 1.0%, which interest shall be payable in cash monthly in arrears and shall be payable on the earlier to occur of (x) the first day of the first month following any extension of credit by the Lender for our credit, (y) the date of any prepayment pursuant to the New Debt Agreement, or (z) the maturity date. The New Convertible Term Loan will be “interest-only” until December 31, 2025, subject to extension as provided for in the New Debt Agreement. The “interest-only” period may be extended to June 30, 2026, if (i) prior to December 31, 2025, we have received at least $40,000,000 in net cash proceeds from the issuance equity interests and (ii) the conditions of Additional Term Loan Event I (as defined in the New Debt Agreement) have been satisfied. Subject to certain terms and conditions, the conversion feature grants the Lender or, pursuant to an assignment, any designee thereof, or Conversion Right Holders, the right to convert part or all of the outstanding aggregate original principal amount of the New Convertible Term Loan, plus accrued and unpaid interest, into shares of our common stock at a conversion price equal to $7.00, subject to customary adjustment provisions. The Conversion Right Holders have the further right to convert part or all of the outstanding principal amount of the second and third tranches of the New Convertible Term Loan, plus accrued and unpaid interest, into shares of our common stock at a conversion price equal to the greater of (i) $4.854, subject to customary adjustment provisions, and (ii) the lower of (a) 150% of the average of the closing sale price of our common stock during the 10 trading days preceding the effective date of such tranche and (b) 150% of the closing sale price of our common stock on the trading day immediately preceding the effective date of such tranche. The conversion rights may be exercised at each Conversion Right Holder's option any time prior to repayment of the New Convertible Term Loan; provided, however, that the Conversion Right Holders will not be permitted to convert part or all of the outstanding aggregate original principal amount of the New Convertible Term Loan without the agreement of the relevant Conversion Right Holder and us if the sum of the amount of debt to be converted; and the aggregate amount of debt previously converted pursuant to any such voluntary conversion, divided by the aggregate of all debt that is then outstanding or that has been repaid other than by conversion exceeds 50%. Additionally, the outstanding principal of the New Convertible Term Loan, plus accrued and unpaid interest, will automatically be converted into shares of our common stock at the applicable conversion price on such date if any, when the closing price per share of our common stock has been equal to or greater than (a) in the case of the outstanding aggregate original principal amount of the New Convertible Term Loan, plus accrued and unpaid interest, $24.00 or, (b) in the case of the outstanding principal amount of the second and third tranches of the New Convertible Term Loan, plus accrued and unpaid interest, three times the applicable conversion price, in each case for the thirty consecutive trading days prior to such date, and the Liquidity Conditions (as defined in the New Debt Agreement) have been satisfied. The New Convertible Term Loan may be repaid at our election and upon notice to the Agent (as defined in the New Debt Agreement) by paying the Lender an amount equal to (i) a prepayment fee equal to (a) 3.0% of the aggregate outstanding principal balance if such prepayment occurs on or prior to the first anniversary of the New Convertible Term Loan, (b) 2.0% of the aggregate outstanding principal balance if such prepayment occurs after the first anniversary, but on or prior to the second anniversary, of the New Convertible Term Loan or (c) 1.0% of the aggregate outstanding principal balance if such prepayment occurs after the second anniversary of the New Convertible Term Loan and before the maturity date; (ii) 4.0% of the original aggregate principal amount of the New Convertible Term Loan and (iii) all other sums due and payable under the New Convertible Term Loan. The New Debt Agreement contains customary affirmative and restrictive covenants, including covenants regarding the incurrence of additional indebtedness or liens, investments, transactions with affiliates, delivery of financial statements, payment of taxes, maintenance of insurance, dispositions of property, mergers or acquisitions, among other customary covenants. We are also restricted from paying dividends or making other distributions or payments on our capital stock, subject to limited exceptions. The New Debt Agreement also includes customary representations and warranties, events of default and termination provisions. The Lender may not engage in any short sales of, or other hedging transactions in, our common stock while any amounts are outstanding under the New Debt Agreement. In connection with the New Debt Agreement, we entered into a Registration Rights Agreement, or RRA, with the Lender, pursuant to which we are required to register for resale shares of our common stock issuable to the Conversion Right Holders upon the conversion of outstanding debt under the New Debt Agreement. Our obligations under the RRA will terminate with respect to a holder of applicable registrable securities if, as of the date we would be required to provide written notice of such registration, (x) the aggregate number of registrable securities then issued and issuable to such holder and to such holder’s affiliates, together with all other shares then held beneficially and/or of record by such holder and its affiliates, does not exceed 7.0% of our then-total shares issued and outstanding (calculated including all such registrable securities and other shares), or (y) we and such holder mutually reasonably agree that all registrable securities then issued and issuable to such holder and its affiliates may then be sold by such holder without the requirement to be in compliance with Rule 144 promulgated under the Securities Act, or Rule 144, and otherwise without restriction or limitation pursuant to Rule 144. Under ASU 2020-06 the embedded conversion feature was not required to be bifurcated and recognized separately, as a result the convertible debt including the conversion feature has been recognized as a single unit of debt. The debt refinancing under the New Debt Agreement was recognized as an extinguishment of debt under ASC 470-50, and the difference between the reacquisition price and carrying value was recognized on the Consolidated Statement of Loss as a loss on extinguishment of debt. Associated third-party issuance costs have been recognized against the single unit of debt and will be amortized into interest expense over the term of the loan. As of June 30, 2025 and December 31, 2024, the New Convertible Term Loan balance was comprised of the following (in thousands):
| June 30, |  |  | December 31, |
