(7) Stockholders’ Equity
Common Stock
On November 22, 2022, the Company filed a third amendment (the “Amendment”) to the Company’s Certificate of Incorporation (as amended, the “Certificate of Incorporation”) with the Secretary of State of the State of Delaware to effect a 1-for-30 stock split of all of the Company’s issued and outstanding shares of Common Stock. The Amendment provided that, at the effective time of the Reverse Stock Split, every 30 shares of the Company’s issued and outstanding Common Stock were automatically combined into one validly issued, fully paid and non-assessable share of Common Stock, without effecting a change to the par value per share. The Reverse Stock Split affected all shares of the Company’s Common Stock outstanding immediately prior to the effective time of the Reverse Stock Split, as well as the number of shares of Common Stock available for issuance under the Company’s equity incentive plans. In addition, the Reverse Stock Split effected a reduction in the number of shares of Common Stock issuable upon the exercise of stock options and warrants outstanding immediately prior to the effectiveness of the Reverse Stock Split with a corresponding increase in exercise price per share. The Reverse Stock Split also triggered a proportionate adjustment to the number of shares of Common Stock issuable upon the conversion of our Series D convertible preferred stock, par value of $0.001 per share (“Series D Preferred Shares”). All historical per share data, number of shares outstanding, and other common stock equivalents for the periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the Reverse Stock Split.
Preferred Stock
The Company has issued 280,898 shares of Series D Preferred Shares, all of which were issued and outstanding as of June 30, 2026. Series D Preferred Shares are convertible to common stock on a one-for-thirty basis, representing approximately 9,363 shares of common stock upon conversion. Series D Preferred Shares are not callable by the Company. The holder of the preferred stock is entitled to receive, and we shall pay, dividends on shares equal to and in the same form as dividends actually paid on shares of common stock when, and if, such dividends are paid on shares of common stock. No other dividends are paid on the preferred shares. Preferred shares have no voting rights. Upon liquidation, dissolution, or winding-up of the Company, whether voluntary or involuntary, the preferred shares have preference over common stock. The holder of Series D Preferred Shares has the option to convert said shares to common stock at the holder’s discretion.
Rights Plan
On December 21, 2022, the Company’s Board of Directors adopted a limited duration stockholder rights plan (the “Rights Plan”) expiring December 20, 2023 and declared a dividend of one preferred share purchase right for each outstanding share of common stock to stockholders of record on January 5, 2023 to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, par value $0.001 per share, of the Company for an exercise price of $58.00 once the rights become exercisable, subject to the terms of and adjustment as provided in the related rights agreement.
On December 18, 2023, the Company entered into Amendment No. 1 to the Rights Agreement between the Company and Equiniti Trust Company, as Rights Agent (the "Amendment"), which extended the Final Expiration Date (as defined in the Rights Plan) to December 20, 2024. On December 12, 2024, the Company entered into Amendment No. 2 to the Rights Agreement between the Company and the Rights Agent, which extended the Final Expiration Date to December 20, 2025, unless the Final Expiration Date is further extended by the Company or the rights subject to the Rights Plan are earlier redeemed or exchanged by the Company in accordance with the terms of the Rights Plan. On December 12, 2025, the Company entered into Amendment No. 3 to the Rights Agreement between the Company and the Rights Agent, which extended the Final Expiration Date to December 20, 2026. All other terms and conditions of the Rights Plan remain unchanged.
