Issuance of common stock for cash On August 31, 2022, the Company entered into a Controlled Equity Offering Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. and B. Riley Securities, Inc. (collectively, the “Agents”), pursuant to which the Company may issue and sell from time-to-time shares of the Company’s common stock through the Agents, subject to the terms and conditions of the Sales Agreement. On April 6, 2023, the Company and B. Riley Securities, Inc. mutually agreed to terminate B. Riley Securities, Inc.’s role as a sales agent under the Sales Agreement. During the year ended June 30, 2024, the Company sold 333,749 shares of common stock under the Sales Agreement for total net proceeds of approximately $9.3 million after deducting 3% commissions and expenses of approximately $377,000. During the year ended June 30, 2023, the Company sold 753,925 shares of common stock under the Sales Agreement for total net proceeds of approximately $49.5 million after 3% commissions and expenses of approximately $2.0 million. On March 6, 2024, the Company closed a best efforts public offering (the “Offering”) of 1,500,000 shares (the “Shares”) of its common stock, par value $0.001 per share (the “Common Stock”), pre-funded warrants (the “Pre-funded Warrants”) to purchase 600,000 shares of Common Stock, and warrants to purchase up to 1,050,000 shares of Common Stock (the “Common Warrants”) at a combined public offering price of $10.00 per Share, or Pre-funded Warrant, and the associated Common Warrant. The Common Warrants have an exercise price of $15.00 per share and are immediately exercisable upon issuance for a period of five years following the date of issuance. The gross proceeds to the Company from the Offering were approximately $21.0 million, before deducting placement agent fees and offering expenses of approximately $2.5 million, resulting in net proceeds of approximately $18.5 million. Additionally, upon closing the Company issued the placement agent warrants (“Placement Agent’s warrants”) to purchase 105,000 shares of Common Stock exercisable at a per share price of $12.50, which was equal to 125% of the public offering price per share. The Placement Agent’s Warrants are exercisable during a five-year period commencing 180 days from March 6, 2024. The Pre-Funded Warrants were exercised shortly after issuance and the 600,000 shares of Common Stock were issued during the year ended June 30, 2024.

The Company recorded stock based compensation expense relating to the vesting of stock options of approximately $2.8 million and $4.2 million for the years ended June 30, 2024 and 2023, respectively. Issuance and modification of restricted stock units and options: On June 21, 2022, the Company awarded 12,452 restricted stock units (“RSUs”) to the President and CEO under the Company’s 2019 Omnibus Plan. Each RSU awarded to the CEO entitles him to receive one share of Common Stock upon vesting. The RSUs vest in three equal annual installments beginning on the first anniversary grant date. 4,151 and 4,151 RSUs vested in June 2023 and 2024, respectively. On November 23, 2022, the Company awarded 38,198 RSUs to certain employees and a consultant, with a grant date fair value of $61.20 per share. 25% of these RSUs vested on the grant date and the remaining RSUs vest in three equal installments over three years beginning on the first anniversary of the grant date. During the year ended June 30, 2023, 9,550 of these RSUs vested, of which 2,288 shares were withheld in Treasury stock in exchange for payment of withholding tax on behalf of the employees. On November 23, 2022, the Company issued equity awards for the board of directors’ annual compensation. Four directors received 15,564 RSUs with a grant date fair value of $61.20 per share. In addition, three directors received stock options to purchase 19,500 shares of common stock at an exercise price of $61.20 per share with a grant date fair value of $40.60 per share. The equity awards vest quarterly on February 23, 2023, May 23, 2023, August 23, 2023 and earlier of November 23, 2023 or the next annual shareholders’ meeting. During the year ended June 30, 2024, 7,746 of these RSUs vested. These RSUs and options contain certain contractual vesting terms where the vesting can be accelerated outside the Company’s control and as a result, for accounting purposes, are assumed to have been fully vested on the grant date, and accordingly, the Company recognized the total compensation cost of $1,744,192 on November 23, 2022. On November 9, 2023, the Company issued equity awards for the board of directors’ annual compensation. Four directors received 18,270 RSUs with a grant date fair value of $30.10 per share. In addition, two directors received stock options to purchase 18,325 shares of common stock at an exercise price of $30.10 per share with a grant date fair value of $18.30 per share.

During the year ended June 30, 2024, 4,568 of these RSUs vested. In December 2023, the Company terminated five employees and as part of their severance agreement modified their equity awards that had been granted pursuant to the 2019 Omnibus Plan. The modifications included the acceleration of certain stock option awards to purchase a total of 5,623 shares of common stock (“Accelerated Options”), effective on the December Separation Date, as defined in severance agreement (“Separation Date”), and extended the expiration date for one year from the Separation Date for both the Accelerated Options and any vested and unexercised stock options held by the terminated employees as of the Separation Date. Accordingly, the Company remeasured the Accelerated Options based on the stock price of $15.40 per share at the close on the Separation Date and a one-year extension of the term. The net adjustment for the modification was a net credit of $127,199 and was recognized as an adjustment to stock compensation expense during the year ended June 30, 2024. Additionally, 1,030 vesting RSUs were accelerated as of the Separation date. The modified RSUs were remeasured based on the stock price of $15.40 per share at close on the Separation Date and $15,865, was recorded to additional in stock-based compensation for the year ended June 30, 2024 as a result of the modification. In connection with the separation, the Company canceled 18,396 unvested stock options and 1,030 unvested RSUs. Additionally, the Company canceled an additional 13,416 unvested stock options for employees that voluntarily left the company. In June 2023, the Company issued 14,950 RSUs with a grant date fair value of $41.10 per share to the President and CEO under the Company’s 2019 Omnibus Plan.

Pursuant to a former employee’s Separation Agreement, dated April 11, 2022, the Company modified their stock option award granted on August 20, 2021, pursuant to the 2019 Omnibus Plan (“2021 Options Grant”). Pursuant to the terms of the Separation Agreement, effective July 8, 2022 (the “Separation Date”), the Company accelerated the vesting of options scheduled to vest on the first and second anniversary of the grant date as deemed vested (“Accelerated Options”) and after giving effect to the Accelerated Options, extended the exercise period of the total vested outstanding and unexercised options (totaling 7,450 options) to one year following the Separation Date. The unvested portion of the 2021 Option Grant (totaling 4,967 options) was canceled. The modification was remeasured as of July 8, 2022, and the incremental difference in fair value resulted in a net credit to stock based compensation expense of $181,154, due to the original exercise price of $77.40 being greater than the stock price of $18.00 on the remeasurement date, and accordingly was recognized on July 8, 2022. On June 7, 2023, the Company granted stock options to purchase 14,800 shares of Common Stock to certain employees. 20% of the shares underlying the options awarded vested on the grant date, and the remaining 80% will vest in four equal annual installments beginning, on the first grant date anniversary.
