Organization and Description of Business |
Organization and Description of Business | Note 1 – Organization and Description of Business ClearSign Technologies Corporation (ClearSign or the Company) designs and develops products and technologies for the purpose of improving key performance characteristics of industrial and commercial systems, including operational performance, energy efficiency, emission reduction, safety and overall cost-effectiveness. Our patented technologies, embedded in established OEM products as ClearSign Core(TM), and ClearSign Eye(TM) and other sensing configurations, enhance the performance of combustion systems and fuel safety systems in a broad range of markets, including the energy (upstream oil production and down-stream refining), commercial/industrial boiler, chemical, petrochemical, transport and power industries. The Company’s primary technology is its ClearSign Core technology, which achieves very low emissions without the need of external flue gas recirculation, selective catalytic reduction, or higher excess air operation. The Company is headquartered in Seattle, Washington and was incorporated in the state of Washington in 2008. On July 28, 2017, the Company incorporated a subsidiary, ClearSign Asia Limited, in Hong Kong to represent the Company’s business and technological interests throughout Asia. Through ClearSign Asia Limited, the Company has established a Wholly Foreign Owned Enterprise (WFOE) in China – ClearSign Combustion (Beijing) Environmental Technologies Co., LTD. Unless otherwise stated or the context otherwise requires, the terms ClearSign and the Company refer to ClearSign Technologies Corporation and its subsidiary, ClearSign Asia Limited. Liquidity The Company’s technologies are currently in field development and have generated nominal revenues from operations to date to meet operating expenses. In order to generate meaningful revenues, the technologies must be fully developed, gain market recognition and acceptance, and develop a critical level of successful sales and product installations. The Company has historically financed its operations primarily through issuances of equity securities, including $4.8 million in proceeds, net of offering costs, from a stock offering completed on August 24, 2020 and $1.3 million in proceeds, net of offering costs, from a stock offering completed on September 30, 2020. Subsequent to December 31, 2020, the Company raised $3.5 million from the issuance of 750,000 shares of common stock at prices ranging from $4.03 to $5.50 per share through an At The Market (ATM) facility as of March 27, 2021. The Company has incurred losses since its inception totaling $74,874,000 and expects to experience operating losses and negative cash flows for the foreseeable future. Additionally, the outbreak of COVID-19 has caused significant disruptions to the global markets which could impact the Company’s ability to raise additional capital. Based on the Company’s current plans, it has sufficient funds to continue to support its operations for at least twelve months from the date of issuance of these consolidated financial statements. In order to continue business operations beyond twelve months from the date of issuance of these consolidated financial statements, the Company currently anticipates that it will need to raise additional capital. Management believes that the successful growth and operation of the Company’s business is dependent upon its ability to obtain adequate sources of funding through co-development agreements, strategic partnering agreements, or equity or debt financing to adequately support research and development efforts, protect intellectual property, form relationships with strategic partners, and provide for working capital and general corporate purposes. There can be no assurance that the Company will be successful in achieving its long-term plans as set forth above, or that such plans, if consummated, will result in profitable operations or enable the Company to continue in the long-term as a going concern.
