Item 1A. Risk Factors
Our risk factors are described in the “Risk Factors” section of our 2021 Form 10-K. Except as set forth below, there have been no material changes to the risk factors disclosed in the Form 10-K.
Our recurring losses from operations have raised substantial doubt regarding our ability to continue as a going concern.
We have incurred recurring losses since inception and, as of March 31, 2022, had an accumulated deficit of $77.8 million. We anticipate operating losses to continue for the foreseeable future due to, among other things, costs related to research funding, further development of our technology and products and expenses related to the commercialization of our products, and it is possible we will never achieve profitability. As a result, our independent registered public accounting firm included an explanatory paragraph in its report on our consolidated financial statements as of and for the year ended December 31, 2021. Future reports on our consolidated financial statements may include an explanatory paragraph with respect to our ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might be necessary should we be unable to continue as a going concern.
We believe that our existing cash as of March 31, 2022 will be sufficient to fund our operations through to April 2023 and that we will require additional capital to continue our operations and research and development activity thereafter. There can be no assurance, however, that such financing will be available when needed, if at all, or on acceptable terms and conditions. The precise amount and timing of the funding needs cannot be determined accurately at this time, and will depend on a number of factors, including the market demand for our products, the quality of product development efforts, management of working capital, and the continuation of normal payment terms and conditions for purchase of services.
Until such time, if ever, as we can generate substantial product revenue, we expect to finance our working capital requirements through a combination of equity offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research
