Reverse Stock Split

On November 27, 2023, the stockholders of the Company approved a proposal at the Company’s 2023 Annual Meeting of Stockholders (the “Annual Meeting”) to amend the Company’s Certificate of Incorporation to effect a reverse stock split of the Company’s Common Stock, at a ratio between 1-for-5 to 1-for-20, with the ratio within such range to be determined at the discretion of the Company’s Board,

without reducing the authorized number of shares of Common Stock. Following the Annual Meeting, the Board approved a final split ratio of 1-for-20 (1:20). Following such approval, on November 28, 2023, the Company filed an Amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware to effect the 2023 reverse stock split, with an effective time of 12:01 a.m. Eastern Time on November 29, 2023. As a result of the 1:20 2023 Reverse Stock Split, each twenty (20) pre-split shares of Common Stock outstanding automatically combined into one (1) new share of Common Stock without any action on the part of the holders. No fractional shares were issued in connection with the 2023 Reverse Stock Split. In lieu of fractional shares, any person who would otherwise be entitled to a fractional share of Common Stock as a result of the reclassification and combination following the effective time of the 2023 Reverse Stock Split (after taking into account all fractional shares of Common Stock otherwise issuable to such holder) were entitled to receive a cash payment equal to the number of shares of the Common Stock held by such stockholder before the 2023 Reverse Stock Split that would otherwise have been exchanged for such fractional share interest multiplied by the average closing sales price of the Common Stock as reported on the NYSE American for the ten days preceding November 29, 2023.

Lincoln Park Stock Purchase Agreement

​

On August 4, 2023, the Company entered into a purchase agreement, dated as of August 4, 2023 (the “Purchase Agreement”), with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which, under the terms and subject to the satisfaction of specified conditions set forth therein, the Company could have sold to Lincoln Park up to $10.0 million (subject to certain limitations) of Common Stock, from time to time during the term of the Purchase Agreement. Additionally, on August 4, 2023, the Company entered into a registration rights agreement, dated as of August 4, 2023 (the “Registration Rights Agreement”), with Lincoln Park, pursuant to which it agreed to file a registration statement with the SEC, to register under the Securities Act of 1933, as amended (the “Securities Act”), the resale by Lincoln Park of shares of Common Stock that have been or may be issued and sold by the Company to Lincoln Park under the Purchase Agreement. The Company could not sell any shares of Common Stock to Lincoln Park under the Purchase Agreement unless all of the conditions to Lincoln Park’s purchase obligation set forth in the Purchase Agreement were met, including that the resale registration statement that the Company is required to file with the SEC under the Registration Rights Agreement is declared effective by the SEC and a final prospectus relating thereto is filed with the SEC (the date on which all of such conditions are satisfied, the “Commencement Date”).  The registration statement was declared effective on August 11, 2023.

Beginning on the Commencement Date and for a period of up to 24 months thereafter, under the terms and subject to the conditions of the Purchase Agreement, from time to time, at the Company’s discretion, it had the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park was obligated to purchase, up to $10 million of shares of Common Stock, subject to certain limitations set forth in the Purchase Agreement. Specifically, from time to time from and after the Commencement Date, the Company could, at  its discretion, on any single business day on which the closing price of the common stock on the NYSE American is equal to or greater than $3.00, by written notice delivered to Lincoln Park, direct Lincoln Park to purchase up to 5,000 shares of Common Stock on such business day, at a purchase price per share that will be determined and fixed in accordance with the Purchase Agreement at the time the Company delivers such written notice to Lincoln Park (each, a “Regular Purchase”); provided, however, that the maximum number of shares the Company may sell to Lincoln Park in a Regular Purchase may be increased to up to (i) 7,500 shares, if the closing sale price of the Common Stock on the NYSE American on the applicable purchase date is not below $20.00, and (ii) 10,000 shares, if the closing sale price of the Common Stock on the applicable purchase date is not below $40.00; provided, however, that Lincoln Park’s maximum purchase commitment in any single Regular Purchase may not exceed $500,000. The foregoing share amounts and per share prices will be adjusted for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction occurring after the date of the Purchase Agreement with respect to the Common Stock. The purchase price per share of Common Stock sold in each such Regular Purchase, if any, will be based on market prices of the Common Stock immediately preceding the time of sale, calculated as set forth in the Purchase Agreement.

In addition, provided that the Company had directed Lincoln Park to purchase the maximum amount of shares that it is then able to sell to Lincoln Park in a Regular Purchase on a particular business day on which the closing price of the common stock on the NYSE American is equal to or greater than $4.00, then in addition to such Regular Purchase, the Company may, in its sole discretion, also direct Lincoln Park to purchase additional shares of Common Stock in an “accelerated purchase,” and one or more “additional accelerated purchases” on the business day immediately following the purchase date for such Regular Purchase, as provided in the Purchase Agreement. The purchase price per share of Common Stock sold to Lincoln Park in each accelerated purchase and additional accelerated purchase, if any, will be based on market prices of the Common Stock at the time of sale on the applicable purchase date for such accelerated purchase and such additional accelerated purchase(s), as applicable, calculated as set forth in the Purchase Agreement. There are no upper limits on the price per share that Lincoln Park must pay for shares of Common Stock in any purchase under the Purchase Agreement.

The Company controlled the timing and amount of any sales of Common Stock to Lincoln Park pursuant to the Purchase Agreement. Lincoln Park had no right to require the Company to sell any shares of Common Stock to Lincoln Park, but Lincoln Park was obligated to make purchases as the Company directs, subject to certain conditions.

As consideration for Lincoln Park’s commitment to purchase shares of Common Stock at the Company’s direction pursuant to the Purchase Agreement, the Company issued 10,573 shares of Common Stock to Lincoln Park as commitment shares (the “Initial Commitment Shares”) and agreed to issue 10,573 additional shares of Common Stock to Lincoln Park as commitment shares (the “Additional Commitment Shares” and, collectively with the Initial Commitment Shares, the “Commitment Shares”) at such time as the Company had received an aggregate of $5 million in cash proceeds from Lincoln Park from sales of Common Stock to Lincoln Park, if any, that it elects, in its sole discretion, to make from time to time from and after the Commencement Date, pursuant to the Purchase Agreement.

During the fiscal year ended June 30, 2024, the Company sold 202,595 shares of Common Stock under the Purchase Agreement and received approximately $1.3 million in proceeds. No shares remain available for sale under the registration statement at September 30, 2024.

​

A holder of the 2024 Pre-Funded Warrants and the Series E Warrants may not exercise any portion of such holder’s 2024 Pre-Funded Warrants or the Series E Warrants to the extent that the holder, together with its affiliates, would beneficially own more than 4.99% (or, at the election of the holder, 9.99%) of the Company’s outstanding shares of Common Stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to the Company, the holder may increase the beneficial ownership limitation to up to 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to the exercise.

​

​

If at the time of exercise on a date that is after the Initial Exercise Date, there is no effective registration statement or the prospectus contained therein is not available for the issuance of shares of Common Stock to the holders of the Series E Warrants, the Series E Warrants may be exercised, in whole or in part, at such time by means of a “cashless exercise.”  If at the time of exercise on a date that is after the 60th day anniversary of the Initial Exercise Date, there is no effective registration statement or the prospectus contained therein is not available for the issuance of shares of Common Stock to the holders of 2024 Pre-Funded Warrants, the 2024 Pre-Funded Warrants may also be exercised, in whole or in part, at such time by means of a “cashless exercise.”

The registration statement was filed with the SEC on April 16, 2024 and declared effective by the SEC on April 24, 2024.

​
