The following table summarizes information about shares issuable under warrants outstanding during the three months ended March 31, 2025 and 2024:

The total intrinsic value of all outstanding warrants aggregated $-0- and $2,128,320 as of March 31, 2025 and December 31, 2024, respectively and the weighted average remaining term was 48.5 and 52.3 months as of March 31, 2025 and 2024, respectively.

The following table summarizes the range of exercise prices and weighted average remaining contractual life for outstanding and exercisable warrants to purchase shares of Common Stock as of March 31, 2025:

On February 13, 2025, the Company issued pre-funded units, each consisting of one-prefunded warrant (to purchase a total of 4,907,500 shares of Common Stock), one Series A warrant and one Series B warrant along with the sale of units, each consisting of one share of Common Stock, one Series A warrant and one Series B warrant. The Series A and Series B warrants were exercisable only upon receipt of stockholder approval (the “Stockholder Approval”) to approve each of (i) certain terms in the Series A warrants and Series B warrants and the issuance of the shares of Common Stock issuable upon the exercise of such warrants, as may be required by the applicable rules and regulations of The Nasdaq Stock Market LLC and (ii) if necessary, a proposal to amend the Company’s Articles of Incorporation, as amended, to increase the authorized share capital of the Company to an amount sufficient to cover the shares of Common Stock issuable upon the exercise of the Series A warrants and Series B warrants. The Series A Warrants were exercisable commencing upon the date of public notice of the Stockholder Approval (the “Warrant Stockholder Approval Date”) until five years after the Warrant Stockholder Approval Date, and the Series B Warrants were exercisable commencing upon the Warrant Stockholder Approval Date until two and one-half years after the Warrant Stockholder Approval Date. Both the Series A and Series B warrants contain reset provisions that are activated upon the date Stockholder Approval is obtained. The warrant terms provide for net cash settlement outside the control of the Company under certain circumstances. As such, the Company is required to treat these warrants as derivative liabilities which are valued at their estimated fair value at their issuance date and at each reporting date with any subsequent changes reported in the condensed consolidated statements of operations as the change in fair value of warrant derivative liabilities. Furthermore, the Company re-values the fair value of warrant derivative liability as of the date the warrant is exercised with the resulting warrant derivative liability transitioned to change in fair value of warrant derivative liabilities through the condensed consolidated statement of operations.

The pre-funded warrants were all exercised within days of their issuance therefore their total fair value was estimated to be $1,803 at the time of their exercise which remained the same as their fair value as of the date of issuance. The following are the assumptions used in calculating the estimated fair value of the pre-funded warrants to purchase Common Stock which were effective and exercisable upon issuance on February 13, 2025:

During the three months ended March 31, 2025, the pre-funded warrants to purchase 4.907,500 shares of Common Stock were fully exercised. In conjunction with the exercise of the pre-funded warrants, the Company transitioned the related warrant derivative liability totaling $1,803 to equity as of their exercise date. The warrant derivative liability related to the pre-funded warrants was $-0- as of March 31, 2025.

On June 25, 2024, the Company issued Series A and prefunded warrants to purchase a total of 88,411 shares of Common Stock along with the sale of Common Stock. The Company also issued Series B Warrants that will be issuable and exercisable at any time or times on or after the date that relevant stockholder approval is obtained in addition to the Series A warrants that are not included in outstanding warrants until such time as relevant stockholder approval is obtained. Both the Series A and Series B warrants have reset provisions that are activated upon the date relevant stockholder approval is obtained. The warrant terms provide for net cash settlement outside the control of the Company under certain circumstances. As such, the Company is required to treat these warrants as derivative liabilities which are valued at their estimated fair value at their issuance date and at each reporting date with any subsequent changes reported in the condensed consolidated statements of operations as the change in fair value of warrant derivative liabilities. Furthermore, the Company re-values the fair value of warrant derivative liability as of the date the warrant is exercised with the resulting warrant derivative liability transitioned to change in fair value of warrant derivative liabilities through the condensed consolidated statement of operations.

The Series B warrants issued in this transaction become issuable and exercisable on the date that relevant stockholder approval is obtained, if ever. Relevent stockholder approval was obtained on December 17, 2024 which activated the Series A and B warrants. Both the Series A and Series B warrants also contain price and warrant reset provisions that were activated upon the date of relevant stockholder approval. The reset provisions increased the number of common shares issuable under the Series A warrant from 59,761 to 298,805 shares and the exercise price per Series A warrant was reduced from $50.20 to $10.04 per share effective December 17, 2024. In addition, the Series B warrants became effective and exercisable upon relevant stockholder approval on December 17, 2024 which resulted in 238,339 common shares issuable under the Series B warrants with an exercise price of $0.001 per share effective December 17, 2024. The Company recognized the full Series B warrant derivative liability value of $2,865,727 as of the date of relevant stockholder approval when it became effective and exercisable of which $454,150 was recorded in equity and $2,411,577 was charged as a loss in the consolidated statement of operations for the year ended December 31, 2024.

	Issuance date assumptions			December 31, 2024 assumptions			March 31, 2025 assumptions
