Secured Promissory Note In connection with the Merger (Note T), on August 30, 2023, the Company and Nantahala, entered into a secured promissory note payable by Zevra to Nantahala in the original principal amount of $5.0 million (the "Nantahala Note"). The Nantahala Note initially bore interest at 9.0% per annum, payable quarterly in arrears in cash. The interest rate increased to 12.0% per annum effective March 1, 2024, as the Nantahala Note remained unpaid six months from its issue date. The additional 3.0% interest would have been paid in shares of Zevra's common stock based on the volume weighted average trading price ("VWAP") of Zevra's common stock during the twenty consecutive trading days ending on the date before such interest payment date. Beginning on the first interest payment date following the second anniversary of the Nantahala Note, and on each interest payment date thereafter, Zevra was required to make $0.6 million amortization payments on the Nantahala Note until it was paid in full. All principal and unpaid interest on the Nantahala Note would have been due on August 30, 2026, the third anniversary of the Nantahala Note. Zevra was entitled to prepay the Nantahala Note at any time without penalty. The Nantahala Note was secured by Zevra’s interest in (i) the loan assets under the Loan Purchase Agreement described in Not e T; (ii) the note assets under the Note Purchase Agreement described in Note T; (iii) the Bridge Loan described in Note T; and (iv) the proceeds therefrom. The Company used the proceeds from the Nantahala Note, along with $12.0 million in cash and 98,683 shares of Zevra's common stock, to acquire Acer's term loans, as more fully described in Not e T. In April 2024, the Nantahala Note was repaid in full and terminated. At the time of repayment, Nantahala elected to receive a cash payment in lieu of shares of Zevra's common stock in exchange for the additional 3.0% interest accrued for the period from March 1, 2024, through April 5, 2024. Margin Account On January 26, 2023, the Company and Wells Fargo, as lender, entered into a revolving margin account agreement. The Company's investments were used as collateral for the loan and the amount the Company was able to borrow was limited to 80-90% of its outstanding investment balance held with Wells Fargo. The margin account bore interest at the Prime rate minus 225 basis-points. As of December 31, 2023, $37.7 million was outstanding under the margin account. The margin loan was included in current liabilities as of December 31, 2023, as the Company expected the outstanding balance to be due and payable in 2024 based on the anticipated level of investment balance expected to be available over the course of fiscal year 2024 to meet the Collateral Requirement. In April 2024, the Company repaid the outstanding balance under the margin account with Wells Fargo, and upon such repayment, the margin capabilities were removed from the account. Term Loans On April 5, 2024 (the "Term Loans Closing Date"), the Company entered into a credit agreement (the “Credit Agreement”) with HCR Stafford Fund II, L.P., HCR Potomac Fund II, L.P., and Perceptive Credit Holdings IV, LP (collectively, the “Lenders”), and Alter Domus (US) LLC, as administrative agent (the “Administrative Agent”). Under the terms of the Credit Agreement, the Lenders provided a senior secured loan facility to the Company in the aggregate principal amount of $100.0 million, which is divided into three tranches as follows: (i) $60.0 million which was funded in full on the Term Loans Closing Date; (ii) $20.0 million which is available to the Company in up to two drawings, each in an amount not to exceed $10.0 million, at the Company’s option until 18 months following the Term Loans Closing Date; and (iii) $20.0 million which is available to the Company upon approval by the FDA of the NDA for MIPLYFFA for the treatment of NPC, at the Company’s option until December 31, 2024 (collectively, the “Term Loans”). The principal amount of the Term Loans outstanding (the “Outstanding Principal Amount”) will bear interest at a rate equal to 3-Month Term SOFR plus 7.00% per annum. If the net product sales for the calendar year ending December 31, 2025, exceed $100.0 million, the Outstanding Principal Amount will bear interest at 3-Month Term SOFR plus 6.00% per annum. If the net product sales for the calendar year ending December 31, 2025, do not exceed $100.0 million, then for any subsequent period of four consecutive fiscal quarters ending on or after March 31, 2026, in which net product sales exceed $125.0 million, the Outstanding Principal Amount will bear interest at 3-Month Term SOFR plus 6.50% per annum. In all cases, the 3-Month Term SOFR rate will be subject to a floor of 4.00% per annum. Interest will be payable quarterly in arrears on the last day of each calendar quarter. The Company has the option to pay up to 25% of the interest in-kind beginning on the Term Loans Closing Date, through and including June 30, 2026. The Company has recognized approximately $1.4 million of interest-in-kind as of December 31, 2024, which is included in long-term debt in the consolidated balance sheet. The Term Loans will mature on the fifth anniversary of the Term Loans Closing Date. In connection with the Credit Agreement, the Company incurred approximately $2.2 million of costs, which primarily consisted of underwriting, legal and other professional fees, and are included as a reduction to the carrying amount of the related debt liability and are deferred and amortized over the remaining life of the financing using the effective interest method. The Credit Agreement contains customary affirmative and negative covenants by the Company, which among other things, will require the Company to provide certain financial reports to the Lenders within 60 days after the end of each of the first three fiscal quarters of each fiscal year and 105 days after the end of each fiscal year, meet certain minimum net product sales amounts, and limit the ability of the Company to incur or guarantee additional indebtedness, engage in certain transactions, and effect a consolidation or merger without consent. In addition, as long as the line of credit remains active, the Company must maintain a minimum cash balance of $20.0 million to ensure the Company can meet its immediate capital needs. The obligations of the Company under the Credit Agreement may be accelerated upon customary events of default, including non-payment of principal, interest, fees and other amounts, covenant defaults, insolvency, material judgments, or inaccuracy of representations and warranties. The Term Loans are secured by a first priority perfected lien on, and security interest in, substantially all current and future assets of the Company. The proceeds of the Term Loans were used to refinance certain existing indebtedness of the Company and its subsidiaries. The Company will use the remaining proceeds to pay fees and expenses related to the debt financing and fund the development and commercialization of OLPRUVA and MIPLYFFA. Long-term debt consisted of the following (in thousands):
