Item 4. Ownership.

The information required by this item with respect to each Reporting Person is set forth in Rows 5 through 9 and 11 of the cover page to this Schedule 13G and is incorporated herein by reference for each such Reporting Person. The ownership percentages reported are based on (i) 15,788,846 shares of Common Stock outstanding as reported in the Issuer’s Prospectus Supplement (File No. 333-269265) filed by the issuer pursuant to Rule 424 of the Securities Act of 1933, as amended, with the U.S. Securities and Exchange Commission (the “SEC”) on February 24, 2023 and the Issuer’s Current Report on Form 8-K filed with the SEC on February 28, 2023; and (ii) 85,882 shares of Common Stock that are issuable upon the exercise of Pre-Funded Warrants that are held by the Reporting Persons, subject to a blocker (the “Blocker”).

As of February 27, 2023, the Reporting Persons hold (i) 1,585,882 shares of Common Stock and (ii) additional shares of Common Stock issuable upon full exercise of the 2,414,118 Pre-Funded Warrants held by the Reporting Persons, subject to a 9.99% Blocker, and additional shares of Common Stock issuable upon full exercise of the 4,000,000 Warrants held by the Reporting Person, also subject to the Blocker. Due to the Blocker, the Reporting Persons are prohibited from exercising the Pre-Funded Warrants and Warrants if, as a result of such exercise or conversion, the holder, together with its affiliates and any persons acting as a group together with such holder or any of such affiliates, would beneficially own more than 9.99% of the total number of shares of Common Stock then issued and outstanding immediately after giving effect to the exercise. Consequently, as of the date of the event which requires the filing of this statement, the Reporting Persons were not able to exercise all of the Pre-Funded Warrants or Warrants due to the Blocker.

As of February 27, 2023, Ionic is the beneficial owner of 1,585,882 shares of Common Stock (the “Shares”). Ionic has the power to dispose of and the power to vote the Shares beneficially owned by it, which power may be exercised by its managers, Mr. O’Neil and Mr. Coulston. Mr. O’Neil and Mr. Coulston, as managers of Ionic, have shared power to vote and/or dispose of the Shares beneficially owned by Ionic. Neither Mr. O’Neil nor Mr. Coulston directly owns any Common Stock of the Issuer. By reason of the provisions of Rule 13d-3 of the Act, each of Mr. O’Neil and Mr. Coulston may be deemed to beneficially own the Shares beneficially owned by Ionic.

Item 5. Ownership of Five Percent or Less of a Class.

If this statement is being filed to report the fact that as of the date hereof the reporting person has ceased to be the beneficial owner of more than five percent of the class of securities, check the following ☐.

Item 6. Ownership of More than Five Percent on Behalf of Another Person.
