SEATTLEJune 18, 2019 — ClearSign Combustion Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), an emerging leader in industrial combustion technologies that improve energy and operational efficiencies while dramatically reducing emissions, today announces that the Company has entered into a collaborative agreement with ASHCOR with the goal of developing and growing the Company’s business in the flare/incinerator vertical.

The agreement combines ClearSign’s technology and ASHCOR’s expert flare knowledge, business infrastructure and manufacturing capabilities. The agreement covers both forced air flare and vapor combustor systems as well as natural draft flares. Both parties anticipate that this collaboration will provide enhanced low emission flare products to the market as a new offering from a well-established and highly reputable flare supplier. The companies believe that the agreement will result in increased market share for each, development of a new mutual flare business in additional regions and markets, and the ability to provide flare products that are highly differentiated and that provide notable performance benefits.

Under the terms of the agreement, the parties will work together to customize the design and develop a full range of forced draft and natural draft systems. The new product ranges will incorporate ClearSign technology, ClearSign Core™, into the established flare system expertise and proven reputation of ASHCOR. The companies will jointly promote and support this product line.

“We are pleased to announce our first collaborative agreement in one of our target verticals,” said Jim Deller Ph.D., Chief Executive Officer of ClearSign. “ASHCOR is a creative and dynamic company and a good fit with ClearSign. Our respective visions of the opportunities this collaboration can provide are well aligned. We look forward to working with ASHCOR to develop our mutual flare business, which we expect will grow sales and market coverage for both companies,” continued Dr. Deller. “As our first commercial alliance, and our first formal step in the implementation of our commercialization strategy of including ClearSIgn technology as a “ClearSign Core” in an established equipment suppliers product range, this is significant for ClearSign. We expect to see additional collaborative agreements going forward as we execute on our commercial strategy.”

“ASHCOR is committed to being a clean energy leader both in the U.S. and internationally, and our partnership with ClearSign Combustion further illustrates our commitment to better serve our customers through technological advances in environmentally friendly solutions,” said Andy Smith, CEO of ASHCOR. “Our customers throughout the oil and gas, biogas, landfill, mining and wastewater treatment markets will benefit from the ability to achieve industry leading destruction efficiency of harmful waste gases while emitting significantly lower NOx levels than traditional technology.”
