 of such date. Net tangible book value
per share is equal to our total tangible assets, less our total liabilities, divided by the total number of shares outstanding as of
June 30, 2025.

Our pro forma net tangible book value as of June 30, 2025, was $$7.32 million, or approximately $2.28 per share of Common Stock, based upon3,210,519shares of Common Stock outstanding as of such date. Pro forma net tangible book value per share is equal to our total tangible assets, less our total liabilities, divided by the total number of shares outstanding as of June 30, 2025, after giving effect to the issuance of 723,873 shares of our Common Stock subsequent to June 30, 2025, for net proceeds of approximately $3.35 million pursuant to our warrant inducement offering that closed on September 8, 2025(the “Pro Forma Adjustments”).

After giving further effect to the assumed sale of our Common Stock in the aggregate amount of $6,413,876 at an assumed offering price of $4.09 per share of Common Stock, the last reported sale price of our Common Stock on The Nasdaq Capital Market on September 30, 2025, and after deducting offering commissions and estimated aggregate offering expenses payable by us, our pro forma as adjusted net tangible book value as of June 30, 2025 would have been approximately $13.5 million, or $2.81 per share of Common Stock. This represents an immediate increase in pro forma net tangible book value of $0.53 per share of Common Stock to our existing stockholders and an immediate dilution in the pro forma as adjusted net tangible book value of $1.28 per share of Common Stock to new investors in this offering at the assumed public offering price.

The following table illustrates this calculation on a per share basis:
