ClearSign Technologies Corporation Announces 1-for-10 Reverse Stock Split to be Effective As of March 16, 2026March 10, 2026 4:05 PM
ACCESS NewswireTULSA, OKLAHOMA / ACCESS Newswire / March 10, 2026 / ClearSign Technologies Corporation (NASDAQ:CLIR) ("ClearSign" or the "Company"), a leader in advanced combustion and sensing technologies that help industrial operators dramatically reduce emissions, increase efficiency and safety, and support the use of cleaner fuels including hydrogen, today announced a 1-for-10 reverse stock split of its outstanding common stock. The reverse stock split will become effective at 12:01 a.m. ET on March 16, 2026. The common stock is expected to begin trading on a split-adjusted basis on the Nasdaq Capital Market ("Nasdaq") under the same symbol "CLIR" when the market opens on March 16, 2026, with the new CUSIP number 185064201.The reverse stock split was approved by the Company's stockholders at the Company's special meeting of stockholders held on February 26, 2026. The reverse stock split is intended to increase the per share trading price of the Company's common stock to regain compliance with the $1.00 minimum bid price requirement for continued listing on Nasdaq. The reverse stock split will reduce the number of outstanding shares of the Company's common stock from approximately 54.1 million shares pre-reverse split to approximately 5.41 million shares post-reverse split.The number of authorized shares of common stock and the par value per share will remain unchanged. As a result of the reverse stock split, every 10 shares of the Company's pre-reverse split common stock will be combined and reclassified into one share of common stock. Proportionate voting rights and other rights of such holders will not be affected by the reverse stock split. No fractional shares will be issued. Stockholders otherwise entitled to a fractional share will receive one whole share rounded up at the participant level with the Depository Trust Company (the "DTC").In accordance with the terms of the Company's outstanding warrants, equity incentive plans and applicable award agreements, the number of shares underlying outstanding warrants and equity awards will be proportionately adjusted, and any exercise prices will be proportionately increased, to reflect the reverse stock split.The Company's transfer agent, VStock Transfer, LLC, is acting as exchange agent for the reverse stock split and will send instructions to stockholders of record regarding the exchange of certificates for common stock, if any, for uncertificated shares of common stock. Stockholders owning shares via a broker or other nominee will have their positions automatically adjusted at the participant level with the DTC to reflect the reverse stock split, subject to the brokers' particular processes, and will not be required to take any action in connection with the reverse stock split.Additional information about the reverse stock split can be found in the Company's Definitive Proxy Statement filed with the Securities and Exchange Commission (the "SEC") on February 2, 2026 (the "Proxy Statement").

Just mentally extrapolating prior and current orders and aligning it with increased market exposure currently.

Thank you for sharing! Why do you think that is?

May need an announcement of a big order which I believe(in my opinion) will be forthcoming in the next few months.

want to see 1.30 break

CLIR

BACT with SCAQMD is a very large TAM. Now come the orders waiting on that technology requirement endorsement

One large order should do it. These single orders are the trickle that becomes a stream that becomes a river.

Show me the money

ClearSign Technologies Provides Update on China Business

https://finance.yahoo.com/news/clearsign-technologies-provides-china-business-133000772.html

Its a long, important PR but worth the read.

Look for a reversal, here.

The company has a lot going on. Sooner or later an announcement will push the over $2.25. Everything that contributes to cleaning the environment must be used.

The flame monitoring devices are attractive to a lot of companies. Optimizing the flame results in cleaner burns and less pollution.

Almost a half a million shares traded today. Bouncing off intra day lows. Look for news over the next few days. This company can be and should be viewed as a climate play.

Been invested here since 2014, knew & accepted it would be a long term investment. With the company’s technological successes & world pressure on climate change this stock can only go one way - UP & it’s happening NOW.

CLIR will run big once a contract is announced.
