New Name Better Reflects Company Strategy and Technology Platforms
Ticker Remains the Same

SEATTLENov. 12, 2019 — ClearSign Combustion Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), an emerging leader in industrial combustion and sensing technologies that improve energy, operational efficiency, safety and dramatically reduce emissions, announces that the Company has changed its name to ClearSign Technologies Corporation effective today, November 12th.  The Company’s ticker “CLIR” will remain the same.  The Company will be rolling out a new corporate website in the coming weeks.  The new website will continue to be found at

This name change is the next step in the evolution of the Company and is a better descriptor of what the Company provides: technology solutions.  The ClearSign CoreTM technology is an advancement which provides best-in-class NOx emissions while also enhancing performance characteristics.  The Company’s sensing technologies have diverse applications to a broad group of industries extending beyond those related to industrial combustion.

“The reasons and timing for the name change are multifold,” said Jim Deller, Ph.D, CEO of ClearSign.  “First off, we are a technology company.  We provide technological enhancements and solutions to our customers.  Secondly, our go-to market strategy emulates a technology company in the fact that our technology is embedded into established manufacturer’s products in the form of ClearSign Core.  Thirdly, we are just beginning to rollout our sensing offerings, which will be included in some current projects. This product line provides technological advancements that have a wider application than just to our traditional market of combustion.”
