| 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. The ownership percentages reported are based on 14,475,904 outstanding shares of Common Stock, as reported in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 13, 2024, and assumes the exercise of pre-funded warrants held by the Reporting Persons for 424,527 shares of Common Stock.
The Master Fund directly holds 1,064,026 shares of Common Stock and 732,156 pre-funded warrants (the “Pre-Funded Warrants”) immediately exercisable for shares of Common Stock at an exercise price of $0.0001 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 after giving effect to such exercise (the “Beneficial Ownership Limitation”). As of the date hereof, the Beneficial Ownership Limitation permits the Reporting Persons to exercise Pre-Funded Warrants for an aggregate of not more than 424,527 shares of Common Stock. In providing the beneficial ownership information set forth herein, the Reporting Persons have assumed that the aggregate remaining Pre-Funded Warrants held by the Reporting Persons are not exercisable due to the Beneficial Ownership Limitation. Perceptive Advisors serves as the investment manager to the Master Fund and may be deemed to beneficially own such shares. Mr. Edelman is the managing member of Perceptive Advisors and may be deemed to beneficially own such shares.
