ClearSign Technologies Corporation Provides Full Year 2023 Update

TULSA, Okla., April 23, 2024 -- ClearSign Technologies Corporation (Nasdaq: CLIR) ("ClearSign" or the "Company"), an emerging leader in industrial combustion and sensing technologies that improve energy, operational efficiency and safety while dramatically reducing emissions, today provides an update on operations for the year ended December 31, 2023.

"We ended 2023 with some commercial momentum and that has carried into the current year," said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "We have been able to deliver and start up our initial boiler burner orders as well as some significant process burner orders. Then just weeks ago, we announced new California BACT emissions thresholds that were set based on the performance of our operational installations, which we believe provides another validating factor for our technology. As a result of these developments we are seeing continued growing interest in our capabilities and subsequent sales opportunities," concluded Dr. Deller.

Recent strategic and operational highlights during, and subsequent to, the end of the fourth quarter 2023 include:

Company Reported Record Quarter and Full Year Revenue: The Company reported Fourth Quarter Revenue of $1.2 million compared to $50 thousand for the fourth quarter of 2022. The Company reported $2.4 million revenue for the full year 2023 compared to $374 thousand for the comparable period in 2022.

Receives Best Available Control Technology (BACT) Determinations for Single and Multi Process-Burner Heaters: ClearSign's process burner performance has been assessed as part of the South Coast Air Quality Management District of California (SCAQMD) periodic public participation process to enhance existing Best Available Control Technology (BACT) determinations and its results have contributed to the establishment of new BACT emissions limits for both single and multi-burner configurations.

Announced Successful Start Up of Multi-Burner Heater in California Project: The first eight burner heaters had a successful startup, had independent source testing confirm that the emissions levels are below guarantee, and are now in operation.

Received First Multi-Boiler Burner Purchase: Partner California Boiler received a letter of intent for four boilers to be fitted with the ClearSign Core™ (Rogue) burners as well as the purchase order for the first boiler of the series. California Boiler has in turn placed their order with ClearSign for the first burner.

Announced Public Offering and Concurrent Private Placement of Common Stock and Warrants: The Company raised approximately $9.3 million in gross proceeds from an underwritten public offering and concurrent private placement, which closed on April 23, 2024.

Cash, cash equivalents and short-term investments were approximately $5.6 million as of December 31, 2023.

There were 38,687,061 shares of the Company's common stock issued and outstanding as of December 31, 2023.
