As previously reported on the Current Report on Form 8-K filed with the SEC on June 6, 2025, the Company completed an Additional Closing (as defined in the Securities Purchase Agreement) on June 5, 2025, pursuant to which the Company sold an additional 938 shares of Series D Preferred Stock for gross proceeds of approximately $750,400.
