Except as otherwise specified in this Amendment No. 6, all items in the Schedule 13D remain unchanged. All capitalized terms used herein and not otherwise defined have the meanings ascribed to such terms in the Schedule 13D. The Reporting Persons are filing this Amendment No. 6 to report certain changes in their beneficial ownership of Shares of the Issuer as a result of the May 2026 Offering, as defined and described in Item 4 of this Schedule 13D.

**Item 4. Purpose of Transaction**

Item 4 of the Schedule 13D is hereby amended to add the following after the last paragraph:

On May 28, 2026, GMS Ventures entered into a securities purchase agreement with the Issuer (the "May 2026 SPA") pursuant to which the Issuer agreed to sell, and GMS Ventures agreed to purchase, 8,539,709 Shares at the price of $0.5855 per Share, for an aggregate purchase price of approximately $5.0 million in a registered direct offering (the "May 2026 Offering"), subject to customary closing conditions. The May 2026 Offering closed on May 29, 2026.
In connection with the May 2026 Offering, on May 28, 2026, the Issuer entered into a warrant amendment agreement (the "May 2026 Warrant Amendment") with GMS Ventures pursuant to which the Issuer agreed to amend certain outstanding common stock warrants to purchase up to an aggregate of 15,488,570 shares of Common Stock previously issued to GMS Ventures in January 2025 and May 2025, with a weighted average exercise price of $1.78 per share, effective upon the closing of the May 2026 Offering, such that the amended warrants have a reduced exercise price of $0.5855 per share. Other than as described herein, the terms of the amended warrants remain unchanged.
