SEC remarks
The sales reported herein were effected within a period of less than six months from the purchases of pre-funded warrants to purchase the Issuers' Common Stock reported in the Form 4 filed by the Reporting Persons on October 28, 2025. However, the sales reported herein were effected at a price lower than the previous purchases that were reported in the Form 4 filed on October 28, 2025, such that no profits have been earned by the Reporting Persons, and so the Reporting Persons have no additional liability under Section 16(b).
