CDT Environmental Technology Investment Holdings Regains Compliance
with Nasdaq Minimum Bid Price Requirement
SHENZHEN, China, July 7, 2026 (GLOBE NEWSWIRE)
-- CDT Environmental Technology Investment Holdings Limited (NASDAQ: CDTG) (the “Company” or “CDT”),
a leading provider of waste treatment systems and services throughout China, today announced that it received on June 30, 2026 a
written notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) that the Company
has regained compliance with the minimum bid price requirement for continued listing set forth in Nasdaq Listing Rule 5550(a)(2), which
requires listed securities, including the Company’s ordinary shares, to maintain a minimum bid price of $1.00 per share.
The staff of Nasdaq’s Listing Qualifications
Department made this determination of compliance after the closing bid price of the Company’s ordinary shares was at $1.00 per
share or greater for the 10 consecutive business days prior to the date of the notice. Accordingly, the Company has regained compliance
with Nasdaq Listing Rule 5550(a)(2), and Nasdaq considers the prior minimum bid price deficiency matter now closed.
