The number of shares of common stock underlying our outstanding warrants and outstanding preferred stock
is significant in relation to our currently outstanding common stock. Conversion or exercise of such
outstanding convertible securities will cause dilution to holders of our common stock, and could cause
downward pressure on the market price for our common stock.
The number of shares of common stock issuable upon conversion of our outstanding preferred stock and exercise of outstanding warrants is significant in relation to the number of shares of our common stock currently outstanding.
As of February 15, 2019,we have warrants to purchase 599,293 shares of common stock outstanding, with exercise prices ranging from $29.68 to $43,848 with a weighted-average exercise price of $50.23.
Through February 15, 2019, shares of our Series F Preferred Stock have been converted into 279,526 shares of our common stock. As of February 15, 2019, there were 535 shares of Series F Preferred Stock outstanding, convertible into an aggregate of 18,190 shares of common stock. The certificate of designation for our Series F Preferred Stock contains an anti-dilution provision, which provision requires the lowering of the applicable conversion price, as then in effect, to the purchase price per share of common stock or common stock equivalents issued in the future. If the effective price per share on a common-stock equivalent basis in a future equity offering is lower than the then-current conversion price of the Series F Convertible Preferred Stock, then such conversion price shall be reduced to such lower price and additional shares of common stock will be issuable upon the conversion of the of the Series F Convertible Preferred Stock. To the extent the outstanding shares of Series F Convertible Preferred Stock become exercisable for additional shares of common stock, holders of our common stock will experience further dilution.
If any security holder determines to sell a substantial number of shares into the market at any given time, there may not be sufficient demand in the market to purchase the shares without a decline in the market price for our common stock. Moreover, continuous sales into the market of a number of shares in excess of the typical trading volume for our common stock could depress the trading market for our common stock over an extended period of time.
In addition, the fact that our stockholders, option holders and warrant holders can sell substantial amounts of our common stock in the public market, whether or not sales have occurred or are occurring, could make it more difficult for us to raise additional financing through the sale of equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate, or at all.
The rights of holders of our capital stock will be subject to, and could be adversely affected by, the rights of
holders of our outstanding preferred stock and stock that may be issued in the future.
Our board of directors has authority, without further stockholder approval, to issue additional shares of preferred stock with such rights, preferences and privileges as our board may determine. These rights, preferences and privileges may include dividend rights, conversion rights, voting rights and liquidation rights that may be greater than the rights of our common stock.
Our board of directors has previously approved, pursuant to this authority, the issuance of preferred stock, and we have 535 shares of Series F Preferred Stock outstanding as of February 15, 2019. As described therein, upon liquidation, dissolution or winding-up of the Company, holders of our Series F Preferred Stock have the right to receive, out of the assets, whether capital or surplus, of the Company an amount equal to the par value, plus any accrued and unpaid dividends thereon, for each share of such preferred stock held by such holder before any distribution or payment shall be made to the holders of our common stock, and, following such payment, such holders are entitled to receive the same amount that a holder of common stock would receive if such preferred stock was fully converted, pari passu with all the holders of common stock.
Our board of directors may issue additional series of preferred stock. As a result, the rights of holders of our capital stock will be subject to, and could be adversely affected by, the rights of holders of any stock that may be issued in the future.
We have a large number of authorized but unissued shares of stock, which could negatively impact a potential
investor if they purchased our common stock.
At a special meeting of our stockholders on December 28, 2018, our stockholders approved a reverse split of our outstanding common stock at a ratio in the range of 1-for-2 to 1-for-14. Following such special meeting, our board of directors approved a 1-for-14 reverse split of our issued and outstanding shares of common stock.
