Stockholders’ Equity	Stockholders’ EquityAs of December 31, 2021, our authorized share capital consists of 1,000,000 shares of preferred stock and 270,000,000 shares of capital stock designated as common stock. As of December 31, 2021, we had 131,793,660 shares of common stock issued and outstanding. We do not have any shares of preferred stock issued and outstanding. As described in Note 1, on October 12, 2021, the Merger was consummated. In accordance with applicable guidance, the equity structure of Appgate has been restated in all comparative periods up to the closing date of the Merger to reflect the number of shares of Appgate’s common stock, $0.001 par value per share, issued to Legacy Appgate’s sole shareholder in connection with the Merger. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Appgate common stock prior to the Merger have been retroactively restated to reflect the new equity structure of Appgate post-merger.
