Note 2 - Liquidity, Going Concern and Management Plans

The accompanying audited consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the continuity of operations, realization of assets, and liquidation of liabilities in the normal course of business.

The Company had cash and cash equivalents of $134.9 million, a working capital deficiency of $70.6 million and an accumulated deficit of $626.5 million as of December 31, 2020. The Company incurred a $599.4 million net loss for the year ended December 31, 2020. Since inception, the Company’s operations have been financed primarily through the sale of equity and debt securities. The Company has incurred losses from operations and negative cash flows from operating activities since inception and expects to continue to incur substantial losses as it continues to fully ramp up its operating activities. While we expect to continue incurring losses in the foreseeable future, we successfully raised $181.0 million in October 2020, net of offering expenses, through a public offering of our common stock.

On February 2, 2021, the Company issued $402.5 million of convertible notes (“2026 Notes”) dated February 2, 2021. The 2026 Notes will bear interest from February 2, 2021 at a rate of 3.25% per annum, payable semiannually in arrears on February 15 and August 15 of each year, beginning on August 15, 2021. The 2026 Notes will mature on February 15, 2026, unless earlier converted, redeemed, or repurchased.

The net proceeds from this offering were approximately $391.4 million, after deducting a discount and estimated offering expenses payable by the Company. The Company intends to use the proceeds from this offering for general corporate purposes, including working capital, business development, sales and marketing activities and capital expenditures.

The net proceeds from the public sale of common stock and the issuance of the 2026 Notes provide us with the necessary liquidity to continue as a going concern for at least one year from the date of these financial statements.

In addition to the foregoing, the Company cannot predict the long-term impact on its development timelines, revenue levels and its liquidity due to the worldwide spread of COVID-19. Based upon the Company’s current assessment, it does not expect the impact of the COVID-19 pandemic to materially impact the Company’s operations.
