18. Common Stock

Our certificate of incorporation, as amended, authorizes the issuance of up to 12,500,000 shares of common stock, $0.01 par value per share.

On October 8, 2021, the Company filed an automatic shelf registration statement on Form S-3 (File No. 333-260152) (the “2021 TSRI Shelf”) which contains (i) a base prospectus, which covers the offering, issuance and sale by the Company of up to $5,000,000 in the aggregate of shares of common stock from time to time in one or more offerings; and (ii) a sales agreement prospectus, which covers the offering, issuance and sale by the Company of up to $4,167,000 in the aggregate of shares of common stock that may be issued and sold from time to time under an at-the-market sales agreement (the “2021 ATM”) by and between the Company and A.G.P./Alliance Global Partners, as sales agent (the “2021 Agent”). The $4,167,000 of common stock that may be offered, issued and sold under the sales agreement prospectus is included in the $5,000,000 of shares of common stock that may be offered, issued and sold by the Company under the base prospectus. Upon termination of the sales agreement, any portion of the $4,167,000 included in the sales agreement prospectus that is not sold pursuant to the sales agreement will be available for sale in other offerings pursuant to the base prospectus and if no shares are sold under the agreement, the full $4,167,000 of securities may be sold in other offerings pursuant to the base prospectus. Under the 2021 ATM, we pay the 2021 Agent a commission rate equal to 3.0% of the gross sales price per share of all shares sold through the 2021 Agent under the sales agreement.

During the three months and nine months ended February 28, 2022, we sold an aggregate of 142,500 shares of common stock pursuant to the 2021 ATM for total gross proceeds of $1,965,623 at an average selling price of $13.79 per share, resulting in net proceeds of approximately $1,821,090 after deducting $144,533 in commissions and other transactions costs.

The 2021 TSRI Shelf is currently our only active shelf-registration statement. We may offer TSR common stock registered under the 2021 TSRI Shelf from time to time in response to market conditions or other circumstances if we believe such a plan of financing is in the best interests of our stockholders. We believe that the 2021 TSRI Shelf provides us with the flexibility to raise additional capital to finance our operations as needed. However, there is no assurance we will be successful in doing so.
