Total common stock authorized to be issued as of June 30, 2023 was 1,000,000,000 shares, with a par value of $0.0001 per share. As of June 30, 2023 and December 31, 2022, there were 107,058,624 and 103,153,337 shares of our common stock outstanding, respectfully.
On January 31, 2022, we entered into an At Market Issuance Sales Agreement with H.C. Wainwright & Co., LLC (“Wainwright”), pursuant to which we may offer and sell, from time to time, shares of our common stock, par value $0.0001 per share, for aggregate gross proceeds of up to $100,000, through or to Wainwright, as agent or principal. We are not obligated to sell shares of our common stock under the sales agreement with Wainwright. Sales of shares of our common stock sold under the sales agreement are made pursuant to an effective shelf registration statement on Form S-3 in the amount of $200,000 filed with the SEC on February 1, 2022. During the six months ended June 30, 2023, we sold 1,715,136 shares of our common stock for aggregate net cash proceeds of $995. Transaction costs were $32. As of June 30, 2023, $94.4 million of shares of our common stock remains issuable pursuant to the sales agreement with Wainwright.
Stock Repurchase Plan
On January 5, 2023, our board of directors authorized and approved a stock repurchase program for the repurchase of outstanding shares of our common stock with an aggregate value of up to $5,000. The authorization permits us to repurchase shares of our common stock from time-to-time through open market repurchases at prevailing market prices, in accordance with federal securities laws. The stock repurchase plan is expected to be completed over the next twelve (12) months and may be amended or terminated at any time, in the sole discretion of the board. The exact means, number and timing of stock repurchases depend on market conditions, applicable legal requirements and other factors, and have been funded through the liquidation of our bitcoin holdings. During the six months ended June 30, 2023, we repurchased 506,500 shares of our common stock at an aggregate repurchase price of $502.

2020 Convertible Note Warrant
In connection with the issuance of the 2020 Convertible Notes, in 2020, we issued a warrant exercisable for three (3) years for the purchase, initially, of up to an aggregate of 2,160,000 shares of the Company's common stock at an initial exercise price of $4.00 per share. The number of shares and exercise price are each subject to adjustment provided under the warrant. As a result of our underwritten public offering in February 2021, the exercise price of each share decreased to $2.25 per share, and the number of shares for which the warrant is exercisable increased to 3,840,000 shares. Furthermore, in October 2021, we issued shares to the seller of Lyte as purchase consideration at a price of $1.4246 per share, and as a result, the exercise price of
the warrant adjusted accordingly and the number of shares exercisable thereunder increased to 2,811,315. The holder also partially exercised the warrant in 2021. If, at the time of exercise of the warrant, there is no effective registration statement registering, or no current prospectus available for, the issuance of the shares, then the warrant may also be exercised, in whole or in part, by means of a “cashless exercise.” The registration statement registering 2,160,000 shares of our common stock issuable pursuant to the terms of the warrant was declared effective by the SEC on October 27, 2020. In April 2022, we filed a registration statement, as amended, registering 250% of the additional warrant shares as result of the adjustment noted above. The registration statement was declared effective by the SEC on May 2, 2022. The warrant may not be exercised if, after giving effect to the exercise, the investor would beneficially own amounts in excess of those permissible under the terms of the warrant. The warrant expired July 15, 2023.
