Stockholders' Equity |
Stockholders' Equity | 15. Stockholders’ Equity The Company has 50,000,000 authorized shares of capital stock, all of which are designated as common stock with par value of $0.001 per share. Each holder of shares of common stock is entitled to one vote for each share held. At-the-Market Offering On August 24, 2024, the Company’s registration statement on Form S-3 became effective, which allowed it to offer and sell securities from time to time in one or more offerings, up to an aggregate value of $150.0 million, including under its June 2024 Controlled Equity OfferingSM Sales Agreement with Cantor Fitzgerald & Co., pursuant to which the Company may offer and sell from time to time its common stock in an at-the-market (“ATM”) offering. Pursuant to this agreement, the Company agreed to pay the sales agent commissions for their services in acting as agent with respect to the sale of shares through the ATM offering program. The sales commission and expenses related to each of the ATM equity offering program are considered direct and incremental costs and are charged against “Additional paid-in capital” on the Balance Sheet in the period in which the corresponding shares are issued and sold. Through December 31, 2024, the Company had issued and sold a total of 2,197,988 shares of its common stock for aggregate gross proceeds of approximately $119.6 million. Treasury Stock Acquired On March 14, 2022, the Company’s Board of Directors authorized a share repurchase program under which it may repurchase up to $20.0 million of its outstanding common stock. Under this program the Company may purchase shares on a discretionary basis from time to time through open market purchases, privately negotiated transactions or other means, including through Rule 10b5-1 trading plans or through the use of other techniques such as accelerated share repurchases. The timing and amount of any transactions will be subject to the discretion of the Company based upon market conditions and other opportunities that it may have for the use or investment of its cash balances. The repurchase program has no expiration date, does not require the purchase of any minimum number of shares and may be suspended, modified or discontinued at any time without prior notice. No purchases were made during the years ended December 31, 2024 and 2023. Warrants Acquired- Related Party Transaction ​ On May 17, 2023, the Company repurchased outstanding warrants to acquire 76,875 shares of common stock from its chief executive officer at a cost of $1,949. The warrants, which were originally issued on June 7, 2012 (16,875 shares) with an exercise price of $4.00 per share and on July 31, 2013 (60,000 shares), with an exercise price of $4.50 per share, were amended in September 2015 and, as amended, had an expiration date of July 31, 2023. The $1,949 aggregate cash purchase price reflects the difference between the aggregate exercise price of the warrants and the aggregate fair market value of the shares of common stock underlying the warrants, based on the closing price of a share of the Company’s common stock on May 16, 2023, the date of the warrant repurchase agreement. Following the warrant repurchase, the warrants were cancelled and are no longer issued and outstanding.
