ClearSign Technologies receives 180-day extension from Nasdaq to regain compliance

ClearSign Technologies Corp (NASDAQ:CLIR), a $39.37 million market cap company whose stock has gained over 12% in the past week, announced Monday that it has received a 180-day extension from The Nasdaq Stock Market LLC to regain compliance with the minimum $1 bid price requirement for continued listing on the Nasdaq Capital Market. According to InvestingPro data, the stock currently trades at $0.77, having shown significant volatility throughout the year.

According to a statement in a press release, the company was first notified by Nasdaq on April 1 that its common stock had closed below $1 per share for 30 consecutive business days, which is below the minimum bid price required by Nasdaq Listing Rule 5550(a)(2). On Monday, ClearSign received a second letter from Nasdaq granting the extension, giving the company until March 30, 2026, to meet the requirement. InvestingPro analysis shows the company maintains a strong financial position with more cash than debt and a healthy current ratio of 3.56x, though it remains unprofitable over the last twelve months.

As part of its request for the extension, ClearSign notified Nasdaq of its intention to regain compliance by implementing a reverse stock split if necessary. The company stated that if the closing bid price of its common stock reaches at least $1 per share for a minimum of 10 consecutive business days before March 30, 2026, it will regain compliance with the rule.

If ClearSign does not regain compliance during this period, Nasdaq will provide written notification that its common stock will be subject to delisting. The company would then have the option to appeal the determination to a hearings panel, but there is no assurance an appeal would be successful.

ClearSign indicated that Nasdaq’s extension notice does not have an immediate effect on the listing or trading of its common stock, which will continue to trade on the Nasdaq Capital Market under the symbol CLIR.
