Term Loan In June 2017, the Company entered into an amendment (the LSA Amendment) to the Amended and Restated Loan and Security Agreement (as amended, the LSA) with Silicon Valley Bank (SVB). Pursuant to the LSA Amendment, SVB agreed to make loans of up to $7.0 million, comprising (i) a $5.0 million term loan, funded at the closing date (the Term C Loan), and (ii) subject to the achievement of a specified milestone relating to the Company’s research, an additional term loan totaling up to $2.0 million (the Term D Loan), of which $4.1 million was used to repay the Company’s existing loan with SVB, in addition to the final payments totaling $0.4 million. The Term C Loan was scheduled to mature on June 1, 2021 and bore interest at an adjustable annual rate of the prime rate per the Wall Street Journal or successor publication plus one-fifth of one percent (0.20%). The LSA Amendment provided an extension of the interest only period through June 1, 2019, upon the Term D Loan advance. Beginning July 1, 2019, the Company was required to repay the principal amount in 36 equal monthly installments, in addition to the monthly interest payment. In addition, a final payment of 6.5% of the funded amount, or $0.3 million, was due on the maturity date. The final payment fee was accrued as interest expense over the term of the loan and recorded in long-term debt, net of current portion. In August 2018, the Company entered into a second amendment to the LSA (the LSA Second Amendment). Pursuant to the LSA Second Amendment, SVB provided the Term D Loan of $2.0 million, upon the Company’s receipt of $3.0 million in convertible note financing. In addition, a final payment of 6.5% of the funded amount, or $0.1 million, was due on the maturity date. The Company accounted for the financing prospectively as a debt modification. On June 30, 2020, the Company voluntarily prepaid the aggregate outstanding principal balance of $2.8 million and final payments and accrued interest of $0.5 million related to the Term C and Term D Loans, and the LSA was terminated. In conjunction with the Term A and Term B Loans, the Company issued a warrant to SVB to purchase up to 16,474 shares of Series A convertible preferred stock at an exercise price of $2.2615 per share, exercisable at any time following the issuance, with a term of ten years. In connection with the completion of the IPO in June 2020, the preferred stock warrant was adjusted to become a warrant exercisable for 7,809 shares of common stock at an exercise price of $4.77 per share. In conjunction with the Term C Loan entered into in June 2017, the Company issued a warrant to SVB to purchase up to 9,442 shares of common stock at an exercise price of $0.53 per share, exercisable at any time following the issuance, with a term of seven years. The Company estimated the fair value of the warrants granted using the Black-Scholes option-pricing model and recorded the fair value as debt discounts, which were being amortized to interest expense using the effective interest method over the term of the loans. On June 17, 2020, the warrants were cashless exercised for an aggregate of 15,833 shares of common stock.
