In connection with the January 2024 PIPE Financing (as defined below), the Company issued the Pre-Funded Warrants (as defined below) (See Note 6). The Pre-Funded Warrants have an exercise price of $0.001 per share, and were exercisable immediately upon issuance until exercised in full. The gross proceeds from the issuance of these Pre-Funded Warrants was $22,991,015. The Company determined that the Pre-Funded Warrants are freestanding instruments that do not meet the definition of a liability or derivative. The Pre-Funded Warrants are indexed to the Company’s common stock and meets all other conditions for equity classification. Accordingly, the Pre-Funded Warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time issued. The Company also determined that the Pre-Funded Warrants should be included in the determination of basic and diluted earnings per share. `
