Liquidity

We have incurred operating losses and negative cash flows from operations since our inception. Our ability to achieve our long-term business objectives depends upon, among other things, raising additional capital, acceptance of our products and attaining future profitability. We believe we will be successful in raising additional financing from our stockholders or from other sources, in expanding operations and in gaining market share. For example, in July 2018, we successfully completed an initial public stock offering ("IPO") with the sale of 20,700,000 shares of Class A common stock at a price of $15.00 per share, resulting in net cash proceeds of $282.3 million net of underwriting discounts, commissions and offering costs.
