Rule 13d-2(a) under the Act provides that if any material change occurs in the facts set forth in a reporting person’s Schedule 13D, including any material increase or decrease in the percentage of the class beneficially owned, such reporting person promptly shall file an amendment to such Schedule 13D. Rule 13d-2(a) further provides that an acquisition or disposition of securities in an amount equal to one percent (1%) or more of the class of securities shall be deemed “material” for purposes of the foregoing amendment requirement.

On December 8, 2023, the Issuer completed an offering of Securities (the “Company Offering”), which resulted in the ownership percentage of the Securities held by the Reporting Persons to be reduced by one percent (1%) or more of the Securities then outstanding.
