REDUCTION OF EXERCISE PRICE OF WARRANTS TO PURCHASE COMMON STOCK
Pursuant to the terms set forth in the Warrants to Purchases Common Stock, issued on January 28, 2020 (the “Warrants”), such Warrants are subject to adjustment in certain
circumstances, including in connection with stock splits or if the Company sells common stock at a price lower than the then-exercise price of the Warrants. As a result of a registered direct offering that closed on March 23, 2020 (the “March 2020
Offering”), the exercise price of the Warrants was adjusted to $0.30, the per share price to the public in the March 2020 Offering, upon the closing of the March 2020 Offering on March 23, 2020. On October 16, 2020, the Company effected a 1-for-30
reverse stock split, which further adjusted the exercise price of the Warrants to $9.00. As a result of an underwritten public offering that closed on March 19, 2021 (the “March 2021 Offering”), the exercise price of Warrants was further adjusted
to $5.50, the per share price to the public in the March 2021 Offering, upon the closing of the March 2021 Offering on March 19, 2021. As a result of an underwritten public offering that closed on September 17, 2021 (the “September 2021 Offering”),
the exercise price of Warrants was further adjusted to $2.50, the per share price to the public in the September 2021 Offering, upon the closing of the September 2021 Offering on September 17, 2021. As a result of an underwritten public offering
that closed on October 18, 2022 (the “October 2022 Offering”), the exercise price of Warrants was further adjusted to a floor price of $1.65 in the October 2022 Offering, upon the closing of the October 2022 Offering on October 18, 2022. As of
October 18, 2022, there were 197,227 shares of our common stock issuable upon the exercise of outstanding warrants, following such exercise price adjustment.
This Supplement is being filed to reflect the foregoing adjustments in the exercise price of the Warrants, as described above.
