$CLIR It's all guesswork before official information, but here's my guess about the schedule for now… (JAN) Commercial Validation (DONE): Record revenue and a $10M sales pipeline confirmed the technology's market demand. (FEB) Structural Cleanup (IN PROGRESS): Reverse stock split and updated executive "golden parachutes" are grooming the company for a clean acquisition. (MAR–APR) Final Packaging: Year-end financials and "strategic silence" as due diligence and private negotiations peak. (SUMMER–FALL) Exit Window : Official buyout offer. With the technology proven and the structure ready, Zeeco or another major player makes their move.

$CLIR Even if the share price declines ahead of February 26th, it does not alter the fundamental reality: The technology is proven (commercial validation is complete). The infrastructure is in place (Zeeco + Devco + facility expansion). The 'Exit Team' is ready (Basenese & DiGiandomenico on the Board). If Zeeco puts $300–$500 million on the table, they couldn’t care less whether the stock is trading at $0.40 or $0.80 on the open market—they aren't just buying a ticker; they are acquiring a future global industry standard.

$CLIR Zeeco’s Three-Phase Strategic Roadmap: Phase 1: Infrastructure. Acquire a process heater manufacturer (Devco) and expand physical capacity (major facility expansion). Phase 2: Validation. Market ClearSign’s technology under the "Zeeco CS5" brand to prove commercial viability and build customer trust. Phase 3: Acquisition. Once the sales pipeline is secured and the technology is fully integrated into Zeeco’s own heaters (Devco), acquire ClearSign outright to internalize all patent royalties and intellectual property. Darton Zink (CEO of Zeeco) stated in connection with the Devco acquisition that the goal is to become a “comprehensive single-source provider.” ClearSign is the final missing piece of the puzzle that makes this offering globally unique.

$CLIR Interesting. Based on the preliminary proxy statement (PRE 14A) published on January 23, 2026, and previous contract updates, "Change of Control" has been defined very precisely: Executive Protection: The contracts of CEO Jim Deller and other key executives have been updated so that in the event of a change of control (i.e., if the company is acquired), their severance pay has been increased to the equivalent of one year’s salary (up from the previous 6 months). This is a typical "golden parachute" designed to secure management’s benefits during an acquisition. Cooperation Agreements: ClearSign has entered into new "Cooperation Agreements" with certain major investors (such as Clarkson and DiGiandomenico). These agreements explicitly state that they will terminate immediately upon a "Change of Control." This suggests the board wants to "clear the decks" for a potential buyer.

$CLIR What the heck happened AH ? Looks like they tried a mini pump and dump (about a million shares) with a high in the .80s, and then dumped it all.... then they used a few shares to paint the tape red so when browsing the volume later, many would think this was a big selloff and it was not at all.

$CLIR Annoyingly quiet and invisible company. Non-existent daily share trading volume. Six years as a shareholder and I'm on the verge of madness. 😨 Every year we wait, and almost nothing happens. All sorts of things are painted with crayons, the same thing happens every year. Clir is invisible and it's the company's own choice. Few people know anything about the whole company. For example, no articles in the media, nothing. Invisible and small, safe in the arms and control of Zeeco. In this growth year, we vote for a share split so that this little one can survive and move forward again. Hopefully it won't be necessary, but now it looks like it will be.

$CLIR From the 7 Jan 2026 official ClearSign press release: "Fourth quarter revenues also included testing, engineering, flares, and service work, underscoring the continued progression of ClearSign and the growing diversity of our solutions and product mix. As we enter 2026, we believe that our expanded portfolio of low-NOx burners, including our latest Department of Energy-tested, 100% hydrogen-capable flexible fuel process burners, and our new ‘M' Series burner line, along with our advanced flares and flame sensors, strongly positions us in the market. As a result, we believe that, with the increase in traction in the industries we serve and the backlog and pipeline of orders we currently have, we are well-positioned to sustain or exceed this growth trajectory in 2026," concluded Dr. Deller. And we already had some successful shipments this year. Are they doing well? I think so.

$CLIR IMO therevare excellent odds you can make 55.555% gain buying here at .6430 as the stock will hit $1.00 easily within 3 months. Simple math, your 0.357 gain divided by the current price of .643. Math is logical as is much of investing.

$CLIR Thanks for the post Greenpa about the co branded Zeeco with ClearSign burners. The LinkedIn link to Zeeco shows they are pushing ClearSign, especially showing the range of fuels these burners can operate on while beating the highest polution standards and costing significantly less than the standard burners with catalytic converters systems. I keep waiting for that first order from Zeeco’s sales force to drop! So many product lines and so many big name customers. We already have penetrated the market. Now we just need to bring home inquiries into sales and we will all be happy stock holders! Time is getting short however, we need some SALES ASAP!”
