Long-term debt and other borrowings

Loan and Security Agreement (“LSA”)

In June 2018, the Company signed a Loan and Security Agreement (“LSA”) with Bridge Bank (“Bank”), a division of Western Alliance Bank. The purpose of the LSA was to provide long-term financing to the Company through term loans available for borrowing in three tranches up to a maximum of $3.0 million through December 2019 upon the attainment of certain milestones as delineated in the LSA. The first tranche of $0.3 million was borrowed in 2018. Interest on outstanding borrowings under the LSA was charged at a rate of 6% per annum. This loan was secured by substantially all tangible assets of the Company; intellectual property was excluded from the secured collateral but was subject to a negative pledge in favor of the Bank.

The Company was permitted to prepay all, but not less than all, of the term loans at any time upon 10 days written notice, with a prepayment premium beginning at 1.0% initially and declining to 0% after May 11, 2022. The Company was required to pay a final payment equal to 3% of the principal amount funded, which was payable upon the earliest to occur of (i) the maturity date, (ii) acceleration and (iii) the prepayment of the loan.

The Company was required to pay a fee of 3.5% of the aggregate amount of term loans funded by Bank under the LSA within three business days of a sale or other disposition of substantially all of the Company’s assets, a merger or consolidation, a change in control or an initial public offering. This fee became payable upon completion of the Company’s IPO on July 26, 2021 and was paid during the year ended December 31, 2021.

This loan was scheduled to originally mature in May 2022, at which time all outstanding principal and accrued and unpaid interest was due and payable.

In March 2019, the Company entered into a first amendment to the LSA that increased total borrowings to $3.0 million and added a financial liquidity covenant. The amendment was accounted for as a debt modification and no gain or loss was recognized in the Company’s financial statements.

In May 2020, the Company entered into a second amendment to the LSA that increased total borrowings to $5.0 million. The maturity date of the loan was extended to May 11, 2024. The amendment was accounted for as a debt modification and no gain or loss was recognized in the Company’s financial statements. As part of the second amendment, the Company paid a one-time amendment fee and a pro-rated final payment in connection with the amendment. The final payment represents an additional principal payment and is accounted for as a debt discount that will be accreted through the maturity date of the loan based on the effective interest method. The second amendment extended the term of the fee to May 11, 2030.

In August 2020, the Company entered into a third amendment to the LSA that waived an event of default due to failure to meet a financial covenant. The amendment also expanded the definition of permitted indebtedness to include Payroll Protection Plan (“PPP”) loans, and modified financial and restrictive covenants.

In February 2021, the Company entered into a fourth amendment to the LSA. This amendment gave effect to the Company’s conversion to a corporation and its purchase of Denovium, including permitting certain cash and equity consideration linked to continued employment and service requirements, and adding Denovium as co-borrower to the LSA.

In June 2021, the Company entered into a fifth amendment to the LSA. This amendment modified the term loan’s maturity date to June 16, 2023.

In February 2022, the Company entered into a sixth amendment to the LSA. This amendment modified various definitions and terms within the agreement, with no adjustments to the financial terms.

In June 2022, the Company paid off the remaining $2.4 million outstanding balance of the LSA.

Convertible Note

In March 2021, the Company entered into a Note Purchase Agreement to issue and sell $125.0 million convertible promissory notes (the “2021 Notes”) to certain investors. The 2021 Notes accrued interest at 6% per annum. Due to certain embedded features within the 2021 Notes, the Company elected to account for these notes, including all of their embedded features, under the fair value option. The Company has elected to recognize interest expense based on the 6% per annum coupon rate of the Notes, which was included in other long-term liabilities on the condensed consolidated balance sheet through the date of the IPO. Based on the terms of the agreement, the 2021 Notes converted at an 18% discount from the offering price to the public in the IPO. Prior to the conversion, the Company recorded a final fair value adjustment of the 2021 Notes using the Company's common stock price at the IPO. Immediately prior to the completion of the IPO, all outstanding principal under the 2021 Notes and the related accrued interest expense were converted into an aggregate of 9,732,593 shares of our common stock based on an initial public offering price of $16.00 per share.

Equipment Financing

In April and June 2022, the Company received a total of $9.4 million of proceeds from equipment financing arrangements with multiple financial institutions. Terms of the agreements require monthly payments over 42-48 month maturities with imputed interest rates ranging 8%-10%. All outstanding principal and accrued and unpaid interest are due and payable at maturity. These loans are secured by certain tangible assets of the Company and include certain financial liquidity covenants. The Company was in compliance with all applicable financial covenants as of September 30, 2022.
