Shares of ClearSign Technologies Corporation (Nasdaq: CLIR) fell approximately 4% on Friday after the company priced an underwritten public offering of 777,780 shares of common stock at $4.33 per share.
The offering is composed mainly of shares being sold by existing stockholders and is projected to generate gross proceeds of about $3.4 million. In connection with the deal, the company granted the underwriter a 30-day option to buy up to an additional 15% of the shares to cover any over-allotments. If that option is exercised in full, total gross proceeds would rise to roughly $3.9 million.
ClearSign has stated that it intends to allocate the net proceeds from the offering toward working capital, research and development efforts, marketing and sales initiatives, and other general corporate purposes. The company has indicated the offering is expected to close on or about June 1, 2026, subject to customary closing conditions.
Newbridge Securities Corporation is acting as the sole book-running manager for the transaction.
ClearSign develops advanced combustion and sensing technologies aimed at helping industrial operators reduce emissions, boost operational efficiency, and enable the use of cleaner fuels, including hydrogen.
