Hosting call at 5pm ET (2pm PT)



SEATTLE, September 15, 2020 –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 quarter ended on June 30, 2020.


“ClearSign has been able to cross some very significant milestones these past few months,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign.  “In June we were able to announce the multi-unit purchase order from ExxonMobil, a project that we had been working towards for three years.  On the heels of that, a few weeks ago, we announced the completion of the collaboration agreement for our process burner technology with what we believe can only be described as the perfect global partner, Zeeco.  This agreement with Zeeco completes another significant milestone in our commercialization strategy and the tangible development of our process burner business that we laid out mid-2019,” said. Dr. Deller.  “We are very optimistic as we move into the burner testing process for ExxonMobil at our new partner’s test facility, and look forward to completing this phase of the project, at which time we expect to be able to confirm to our customers, new partner and the market at large that ClearSign burners are proven to be ready for wide scale industrial deployment,” continued Dr. Deller.  “Additionally, going forward, we are looking forward to the installation of our first burner pilot sensors, getting performance feedback from customers and moving towards the formal launch of the initial ClearSign Eye™ product.”

“Recent developments have opened the way to start back up and re-engage our boiler burner demonstrations in China. We expect the demonstrations to be solidly underway as soon as we have feet on the ground and the ability to coordinate the much anticipated installation, operation and certification of our fire tube boiler product.”  “It is encouraging to see traction in multiple lines of our business,” concluded Dr. Deller.


Recent strategic and operational highlights during and subsequent to the second quarter 2020 include:


  • Executed Public Stock Offering: The Company completed an offering of 2,587,500 shares of its common stock at a public offering price of $2.00 per share.  The total offering included 337,500 shares issued as a result of the underwriter’s exercise in full of its over-allotment option. Gross proceeds to ClearSign from this offering were approximately $5,175,000.
  • Announced Collaborative Alliance with Zeeco, Inc. to Develop a Joint Product Line of Process Burners: The parties expect to jointly develop, sell and supply a product line of best in class ultra-low NOx burners for the global oil processing and petrochemical industries by combining the Company’s ClearSign Core™ technology with the engineering, global manufacturing and sales footprint of Zeeco. The agreement is contingent on a successful burner validation test at the Zeeco test facility.  We expect the validation test to be completed later this year.
  • Received Multi-Unit Process Burner Order from ExxonMobil: – The order is comprised of a multi-burner performance demonstration and the supply of burners incorporating ClearSign’s breakthrough ClearSign Core NOx reduction technology. The order is the final step in the Company’s process of validating ClearSign Core’s superior NOx emissions technology.
  • Received Multi-Flare Order from ASHCOR: The flares were sold by International Combustion and Controls, a division of California Boiler, and validates the Company’s ‘Asset Lite’ commercialization strategy by including ClearSign technology as ‘ClearSign Core’ in established equipment supplier’s products.


Cash, cash equivalents and short term investments were approximately $5,700,000 on June 30, 2020.


Subsequent to the quarter ending, on August 24th, the Company closed a secondary offering pursuant to which 2,587,500 shares of common stock were issued for gross proceeds of approximately $5,175,000 or $2.00 per share.


Shares outstanding at June 30, 2020 totaled 26,731,261.
