Our authorized capital stock consists of 250,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of preferred stock, $0.01 par value per share. Our Charter authorizes our Board of Directors to classify or reclassify shares of our capital stock in one or more classes or series, to cause the issuance of additional shares of our capital stock, and to amend our Charter without stockholder approval to increase or decrease the number of shares of stock that we have authority to issue. As of March 21, 2022, there were 67,867,500 shares of our common stock issued and outstanding, 3,590,233 shares of common stock reserved for issuance for future grants under the Telos Corporation 2016 Omnibus Long-Term Incentive Plan, and there are no shares of stock issuable upon the exercise of any warrants. There are no shares of preferred stock outstanding. All issued and outstanding shares of our capital stock are fully paid and non-assessable.

Common Stock

Dividend Rights

Voting Rights

Holders of our common stock are entitled to one vote for each share held on all matters properly submitted to a vote of stockholders on which holders of common stock are entitled to vote. We have not provided for cumulative voting for the election of directors in our Charter. The directors will be elected by a plurality of the outstanding shares entitled to vote on the election of directors.

Advance Notice of Stockholder Director Nominations and Proposals

Our Bylaws provide that stockholder nominations for directors or proposals for business at an annual or special stockholders meeting must comply with certain advance notice provisions set forth in our Bylaws.

Maryland Business Combination Act

We are subject to Subtitle 6 of Title 3 of the MGCL, the Maryland Business Combination Act. The Business Combination Act may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer.

Maryland Control Share Acquisition Act

We are subject to Subtitle 7 of Title 3 of the MGCL, the Maryland Control Share Acquisition Act. Our bylaws exempt from the Maryland Control Share Acquisition Act acquisitions of our common stock by any person. If we amend our bylaws to repeal the exemption from the Control Share Acquisition Act, the Control Share Acquisition Act also may make it more difficult for a third party to obtain control of us and increase the difficulty of consummating such an offer.

Preferred Stock

Our Board of Directors is authorized, subject to limitations prescribed by Maryland law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series, and to fix the designation, powers, preferences and rights of the shares of each series and any of its qualifications, limitations or restrictions, in each case without further vote or action by our stockholders. Our Board of Directors can also increase or decrease the number of shares of any series of preferred stock, without any further vote or action by our stockholders. Our Board of Directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock or other series of preferred stock. The issuance of preferred stock, while providing flexibility in connection with possible financings, acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control of our company and might adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock.
