CNEY Receives Nasdaq Notification Regarding Minimum Bid Price Deficiency

LISHUI,China,Jan. 17,2023 -- CN Energy Group. Inc. (the "Company"; NASDAQ: CNEY) today announced that it received a written notice (the "Notification Letter") from The NASDAQ Stock Market LLC ("Nasdaq") on January 13,2023. The Notification Letter notifies that the Company is not in full compliance with the minimum bid price requirement set forth in Nasdaq Listing Rules for continued listing on the Nasdaq Capital Market.

Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of US$1.00 per share,and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. Based on the closing bid price of the Company's Class A ordinary shares for the 30 consecutive business days from November 30,2022 to January 12,2023,the Company no longer meets the minimum bid price requirement.

The Notification Letter does not impact the Company's listing on the Nasdaq Capital Market at this time. In accordance with Nasdaq Listing Rule 5810(c)(3)(A),the Company has been provided 180 calendar days,or until July 12,to regain compliance with Nasdaq Listing Rule 5550(a)(2). To regain compliance,the Company's Class A ordinary shares must have a closing bid price of at least US$1.00 for a minimum of 10 consecutive business days. In the event that the Company does not regain compliance by July 12,the Company may be eligible for additional time to regain compliance.

The Company's business operations are not affected by the receipt of the Notification Letter. The Company intends to monitor the closing bid price of its Class A ordinary shares and may,if appropriate,consider implementing available options,including,but not limited to,implementing a reverse share split of its outstanding Class A ordinary shares,to regain compliance with the minimum bid price requirement under the Nasdaq Listing Rules.
