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 that have been shown to significantly improve key performance characteristics of industrial and commercial systems, including operational performance, energy efficiency, emission reduction, safety and overall cost-effectiveness. Our patented technologies are designed to be embedded in established OEM products as ClearSign Core™ and the ClearSign Eye™ and other sensing configurations in order to 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. Going Concern The Company's financial statements have been presented on the basis that it is a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.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 $11.9 million in proceeds, net of offering costs, from a stock offering completed on February 27, 2018 and $11.6 million in proceeds, net of offering costs, from a stock offering completed on July 20, 2018. The Company has incurred losses since its inception totaling $69,953,000 and expects to experience operating losses and negative cash flows for the foreseeable future. On January 15, 2020, the Company received a letter from The Nasdaq Stock Market advising that for 30 consecutive trading days preceding the date of the letter, the bid price of the Company's common stock had closed below the $1.00 per share minimum required for continued listing on The Nasdaq Capital Market pursuant to listing rules, and therefore the Company could become subject to delisting if it did not regain compliance within the compliance period (or the compliance period as may be extended). Additionally, the outbreak of COVID-19 has caused significant disruptions to the global financial markets which could impact the Company's ability to raise additional capital. Based on its current plans, the Company does not have sufficient funds to continue operating its business at current levels for at least 12 months from the date of issuance of these financial statements. In order to continue business operations, the Company currently anticipates that it will need to raise additional capital. Accordingly, these factors, among others, raise substantial doubt about the Company’s ability to continue as a going concern. 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 product development and commercialization 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 plans as set forth above. The accompanying financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.
