CDT Environmental Technology Investment Holdings Limited Establishes Partnership with Fortune 500 Company's Subsidiary to Jointly Bid for Large-Scale Sewage Treatment Facility in Hengqin, China

CDT Environmental Technology Investment Holdings Limited (NASDAQ: CDTG) ("CDT"), a leading provider of waste treatment systems and services throughout China, announces the formation of a consortium with a wholly-owned subsidiary of a Fortune Global 500 company to jointly bid for a substantial sewage treatment plant project in Hengqin, China. CDT's partner subsidiary is a key participant in China's Belt and Road Initiative, with a multi-billion yuan asset-base and currently with an extensive portfolio of international projects underway, primarily in Asia and Africa. The total contracted value is estimated to be worth approximately 1.16 billion Yuan (USD $160 million) upon award.

The Hengqin project, which is being spearheaded by the Chinese government under an approved budget of 1.16 billion Yuan, consists of three phases, which are expected to ultimately establish a 400,000 tons/day water purification facility spanning 16.4 hectares. Phase 1 aims to achieve an initial treatment capacity of 100,000 tons/day. Construction timelines are subject to factors including site preparation, pipe network construction, and other prerequisites, and the project’s funding has been guaranteed by the local municipalities being served by the facility.

Under the consortium structure, the companies will each leverage their respective strengths by splitting project scopes, with one party potentially leading civil works while the other focuses on equipment supply and process engineering. This strategic partnership combines CDT's extensive waste treatment expertise with its partner's strong engineering capabilities and track record on mega-projects, positioning the consortium favorably to secure this major contract.

"Collaborating with such an exceptional industry leader significantly bolsters our prospects on this vital project for the region," said Yunwu Li, CDT CEO. "By joining forces, we can deliver comprehensive, world-class solutions that ensure the long-term environmental sustainability of Hengqin's waterways and ecosystem."
