[1] In June 2023, the Company issued these tranche A warrants to purchase 2,173,912 shares of common stock (the “Tranche A Warrants”), which may be exercised on a one-for-one basis at any time subject to certain limitations as defined in the agreements between the Company and the investors, for either shares of common stock at an exercise price of $1.59 per share or for prefunded warrants at an exercise price of $1.5899 per prefunded warrant to purchase common stock at a future exercise price of $0.0001 per share. The June 2023 Tranche A Warrants will expire upon the earlier of June 2028 or 30 days following the closing price of the Company’s common stock equaling 200% of the exercise price ($3.18 per share) for at least 40 consecutive trading days. As discussed above, on March 31, 2026, a total of 1,630,434 of the June 2023 Tranche A Warrants were canceled and issued to the Investors, as applicable, as Amended 2023 Tranche A Warrants, which resulted in their reclassification from liability classified to equity classified. A total of 543,478 of the June 2023 Tranche A Warrants were not amended and thus remain liability classified.
[2] As discussed above, on March 31, 2026, a total of 2,060,651 prefunded warrants related to the Company's public equity offering completed in June 2023 were canceled and issued to the Investors, as applicable, as Amended 2023 Prefunded Warrants, which resulted in their reclassification from liability classified to equity classified. Each of these Amended 2023 Prefunded Warrants is exercisable at any time for one share of the Company’s common stock on a one-for-one basis under the terms of the agreements between the Company and the Investors.
