Liquidity	3. LIQUIDITY On April 12, 2018, the Company completed a public offering providing for the issuance and sale of 2,335,937 shares of the Company’s common stock, par value $0.001 per share, at an offering price of $16.00 per share, for net proceeds of approximately $34.6 million, after deducting offering expenses payable by the Company (see Note 10). On June 7, 2018, the Company completed an underwritten offering with Cantor Fitzgerald & Co., as underwriter, providing for the issuance and sale of 2,455,882 shares of the Company’s common stock, par value $0.001 per share, at an offering price of $23.65 per share, for net proceeds of approximately $58.0 million, after deducting offering expenses payable by the Company (see Note 10). Based upon the current status of our product development and commercialization plans, we believe that our existing cash and cash equivalents will be adequate to satisfy our capital needs for at least the next 12 months from the date of filing. We anticipate needing substantial additional financing to continue clinical deployment and commercialization of our lead product SkinTE, development of our other product candidates, and scaling the manufacturing capacity for our products and product candidates, and prepare for commercial readiness. We will continue to pursue fundraising opportunities when available, but such financing may not be available in the future on terms favorable to us, if at all. If adequate financing is not available, we may be required to delay, reduce the scope of, or eliminate one or more of our product development programs. We plan to meet our capital requirements primarily through issuances of equity securities, debt financing, revenue from product sales and future collaborations. Failure to generate revenue or raise additional capital would adversely affect our ability to achieve our intended business objectives.
