CIBC Loan
On February 20, 2020, the Company executed a Loan and Security Agreement with Canadian Imperial Bank of Commerce (“CIBC”), which the Company subsequently amended on April 17, 2020 and December 28, 2020 (as amended, the “CIBC Agreement”). The CIBC Agreement originally provided the Company with the ability to borrow up to $32.0 million in debt financing (“CIBC Loan”) consisting of $17.0 million advanced at the closing of
the agreement (“Tranche A”), with the option to draw up to an additional $8.0 million (“Tranche B”) and an additional financing tranche (“Tranche C”) of up to $7.0 million on or prior to February 20, 2022. Neither Tranche B nor Tranche C was drawn before the option expired.
The CIBC Loan originally had a five-year term maturing on February 20, 2025, which included 24 months of interest only payments followed by 36 months of equal payments of principal and interest.
In April 2020, the Company entered into a First Amendment to CIBC Agreement that changed the maturity date to March 15, 2022, which would be automatically extended to February 20, 2025 if the maturity of all outstanding convertible notes was extended to a date no earlier than May 21, 2025 or all convertible notes converted into convertible preferred stock of the Company. An amendment fee of $0.2 million was paid. The amendment was accounted for as a debt modification and no gain or loss was recognized.
In December 2020, to address certain post-close covenants for which the Company was not in compliance, the Company entered into a Second Amendment to the CIBC Agreement that extended the compliance of such covenants to June 30, 2021.
In March 2021, the Company entered into an Amended and Restated Loan and Security Agreement with CIBC (as amended, the “Amended and Restated CIBC Agreement”) which, among other things, extended the loan maturity date of the CIBC Loan from March 15, 2022 to February 20, 2025, and modified certain financial covenants. Per the amended terms, 36 equal payments of principal plus accrued interest would be due beginning March 31, 2022. In connection with the Amended and Restated CIBC Agreement, the Company paid fees to CIBC of less than $0.1 million which were recorded as a discount on the CIBC Loan and are being accreted over the life of the term loan using the effective interest method. The amendment was accounted for as a debt modification and no gain or loss was recognized.
In June 2021, the Company entered into a First Amendment to the Amended and Restated CIBC Agreement that extended the compliance of certain post-close covenants to March 31, 2022.
In October 2021, the Company entered into a Second Amendment to the Amended and Restated CIBC Agreement, which extended the interest only period of the loan from 24 months to 36 months. Under the amended terms, principal repayment would begin in February 2023. There was no change to the loan interest rate or maturity date.
In October 2022, the Company entered into a Third Amendment to the Amended and Restated CIBC Agreement (the “Third Amendment”) with CIBC, which amended certain provisions of the CIBC Loan. The amendment provided the option to draw up to an additional $20.0 million (“Amended Tranche B”) on or prior to October 31, 2023, which can be drawn in increments of at least $5.0 million. Upon request by the Company, CIBC may, in its sole discretion, make additional term loans of up to $10.0 million (“Amended Tranche C”) at any time. The Third Amendment extended the maturity date of the CIBC Loan from February 20, 2025 to October 31, 2027 and provided for a new interest-only period of 24 months from the signing date of the Third Amendment, with the possibility of an additional extension of such interest only period of up to 12 months, subject to satisfaction of certain conditions set forth in the Third Amendment. The Company paid a commitment fee of less than $0.1 million in connection with the Third Amendment. The amendment was accounted for as a debt modification and no gain or loss was recognized.
In February 2023, the Company drew $20.0 million of the Amended Tranche B which has the same interest rate and repayment terms as Tranche A of the CIBC Loan.
In May 2024, as a result of the Company satisfying certain conditions set forth in the Third Amendment, the Company extended the interest-only period of the CIBC Loan from 24 months to 36 months. Principal repayment will begin in November 2025. There was no change to the loan interest rate, maturity date, or other terms of the loan.
Upon draw of the Amended Tranche B, the financial covenants in the Amended and Restated CIBC Agreement require that, when the cash and cash equivalents of the Company as defined in the Amended and Restated CIBC Agreement is less than $100.0 million, the Company have revenue for the trailing three-month period ending on the last day of each fiscal quarter of not less than 80.0% of the revenue for the trailing three-month period, as set forth in the annual projections delivered to the CIBC. Further, the Company is required to maintain unrestricted cash in an aggregate amount equal to the greater of $20.0 million and the Adjusted EBITDA loss as defined in the Amended and Restated CIBC Agreement for the six-month period ending on any date of determination. As of June 30, 2024, the Company was in compliance with all covenants contained in Amended and Restated CIBC Agreement.
The CIBC Loan bears interest at a floating rate equal to 1.0% above the Wall Street Journal Prime Rate at any time. The CIBC Loan is collateralized by substantially all of the Company’s assets, including cash and cash equivalents, accounts receivable, intellectual property and equipment. The Company may prepay the borrowings under the Amended and Restated CIBC Agreement, subject to certain conditions, including a prepayment fee equal to 2.0% of the principal amount repaid during the first year after the effective date of the Third Amendment or 1.0% of the principal amount prepaid during the second year after the effective date of the Third Amendment.
As of June 30, 2024, the CIBC Loan had an annual effective interest rate of 10.1% per year.
