4. Research and Development Supplies and Other Current Assets

The Company's research and development supplies consist of materials that are currently being manufactured at its contract development and manufacturing organization and are valued at cost, and capitalized for future use. These supplies were $1.4 million and $0 at June 30, 2026 and December 31, 2025, respectively.

Other current assets consist of a $0.4 million note receivable to a shareholder of the Company, Golden Knight Incorporated, LP (the "Note"). The Note is due on January 14, 2027 and has an interest rate of 3.63%. The Company accounts for the note receivable under ASC 310, Receivables. As the note is short-term in nature with a one year maturity, and there is an applicable federal interest rate applied, and the Company expects full repayment at the end of the term, the note is classified as an asset rather than as equity.
