Explanatory Note:

On May 18, 2022, Tantech Holdings Ltd (the “Company”) received a letter (the “Letter”) from The Nasdaq Stock Market LLC (“Nasdaq”) stating that since the Company has not yet filed its Form 20-F for the year ended December 31, 2021 (the “Filing”), it no longer complies with Nasdaq Listing Rules (the “Rules”) for continued listing under Listing Rule 5250(c)(1).

Under Nasdaq’s Rules the Company now has 60 calendar days to submit a plan to regain compliance and if Nasdaq accepts the Company’s plan, Nasdaq can grant the Company an exception of up to 180 calendar days from the Filing’s due date, or until November 14, 2022, to regain compliance.

The Company shall email its plan to Nasdaq no later than July 18, 2022. If Nasdaq does not accept the Company’s plan, the Company will have the opportunity to appeal that decision to a Hearings Panel.

The Letter has no effect on the listing of the Company’s shares at this time and the Company’s common shares will continue to trade on The Nasdaq Capital Market under the symbol “TANH.”
