Our ability to sell securities under the ATM program will be limited until we are no longer subject to the SEC’s “baby shelf” limitations.

In April 2022, the Company completed a PIPE financing, which included the issuance of pre-funded warrants to purchase up to 3,206,020 shares of its common stock at a price per pre-funded warrant of $2.359 to the PIPE Investors. The pre-funded warrants provide that the holder will not have the right to exercise any portion of its warrants if such holder, together with its affiliates, would beneficially own in excess of 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to such exercise (the “Beneficial Ownership Limitation”); provided, however, that the holder may increase or decrease the Beneficial Ownership Limitation by giving 61 days’ notice to the Company, but not to any percentage in excess of 19.99%.
