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. The ownership percentages reported are based on an aggregate of 1,460,157 shares of Common Stock outstanding, as reported by the Issuer in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on August 14, 2024 and after giving effect to the Issuer’s 1-for-25 reverse stock split effected on August 27, 2024 as disclosed in the Issuer’s Current Report on Form 8-K filed with the SEC on August 30, 2024 (the “Reverse Stock Split”), and assume the exercise of pre-funded warrants held by the Reporting Persons for 55,691 shares of Common Stock,

Neither Perceptive Advisors nor Mr. Edelman directly hold any shares of Common Stock or any Pre-Funded Warrants (as defined below). After giving effect to the Reverse Stock Split, the Master Fund directly holds 95,742 shares of Common Stock and 68,192 pre-funded warrants (the “Pre-Funded Warrants”) immediately exercisable for shares of Common Stock at an exercise price of $0.001 per share, subject to the Beneficial Ownership Limitation (as defined below). The terms of the Pre-Funded Warrants provide that the Pre-Funded Warrants may not be exercised if, after such exercise, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) if the Securities Exchange Act of 1934, as amended, more than 9.99% of the shares of Common Stock then issued and outstanding (the “Beneficial Ownership Limitation”). As of the date hereof, the Beneficial Ownership Limitation permits the Reporting Persons to exercise 55,691 of the Pre-Funded Warrants. Perceptive Advisors serves as the investment manager to the Master Fund. Mr. Edelman is the managing member of Perceptive Advisors.
