Tantech Holdings Ltd. (NASDAQ: TANH) received a notification from The Nasdaq Stock Market LLC on March 26, 2026, stating the company is not in compliance with the minimum bid price requirement under Nasdaq Listing Rule 5550(a)(2).

The notification resulted from the closing bid price of Tantech's Class A common shares falling below $1.00 per share for 30 consecutive business days. The company's shares will continue to trade on Nasdaq under the ticker "TANH" without interruption.

Tantech has a 180-day compliance period until September 22, 2026, to regain compliance with the minimum bid price requirement. The company can achieve compliance if its closing bid price reaches at least $1.00 for a minimum of 10 consecutive business days during this period.

If the company implements a reverse stock split to regain compliance, it must complete the split no later than ten business days prior to September 22, 2026. Should Tantech fail to regain compliance by the deadline, it may be eligible for an additional 180-day grace period if it meets certain continued listing requirements and provides written notice of its intention to cure the deficiency.

The company stated it is monitoring the trading price of its Class A common shares and evaluating options to regain compliance, including a potential reverse stock split. Tantech noted there can be no assurance it will be able to regain or maintain compliance with Nasdaq's continued listing requirement.

Tantech specializes in producing bamboo charcoal-based products and has been manufacturing bamboo charcoal home products since 2002. The company entered the home building materials industry in 2024 and established U.S. subsidiaries beginning in 2022.
