China International Development Corporation Limited ("CIDC" or the "Company", together with its subsidiaries, the "Group"; Stock Code: 0264) is pleased to announce the successful establishment of its joint venture company, Flex Fuel Eco Company Limited ("JV Company"), formed in collaboration with Flex Fuel Hydrogen Development Group Limited ("Strategic Partner"), has been officially incorporated. Through a strategic reorganization, the JV Company now serves as the holding entity for FlexFuel Hydrogen Development (Shenzhen) Company Limited ("FFHD"), which has entered into a landmark Strategic Collaboration Agreement with MCC Tiangong Group Corporation Limited ("MCC Tiangong").

The JV Company has rapidly scaled operations, importing and installing *over 60 hydrogen decarbonizing and cleaning stations* across more than 20 strategic locations in the PRC. This strategic initiative underscores the Group's commitment to advancing green energy solutions and capitalizing on growing opportunities in the hydrogen technology sector.

MCC Tiangong, a leading construction enterprise jointly owned by China Minmetals Corporation ("CMC") and Metallurgical Corporation of China Limited ("MCC"), is affiliated with CMC—a state-owned enterprise directly under the Chinese Central Government. This partnership leverages MCC Tiangong's extensive industry network and CIDC's innovative hydrogen technologies.

Hydrogen Cleaning Systems: Technology and Market Penetration

Under the Strategic Collaboration Agreement, FFHD will deploy its proprietary hydrogen injection cleaning systems (branded as Flex Fuel) for engines across automobiles, vessels, aircraft, and heavy machinery.

To date, FFHD has secured multiple service agreements with major PRC conglomerates, including Jilin Dacheng Fangxin Automobile Service Co., Ltd., operator of the renowned "Dacheng Truck Repair" network—one of China's largest automotive repair and maintenance chains.

Operational Expansion and Revenue Outlook

Since its inception, the JV Company has rapidly scaled operations, importing and installing *over 60 hydrogen decarbonizing and cleaning stations* across more than 20 strategic locations in the PRC, including Beijing, Wuhan, Xinjiang, the Northwest region, Guangdong province, and Macau. Service agreements are typically structured for an initial term of two years, extendable upon mutual agreement.

The Group has already commenced revenue generation from these initiatives, with expectations for a sustained and growing income stream.

Future Prospects and Shareholder Value

CIDC commented: "Our collaboration with MCC Tiangong marks a transformative step in positioning CIDC at the forefront of hydrogen innovation. By integrating FFHD's cutting-edge technology with MCC Tiangong's unparalleled market reach, we are poised to capture significant opportunities in China's green energy transition. The Board remains dedicated to exploring new ventures that enhance long-term shareholder value."
