Revenue of $7.3 million and loss per share of $0.11 impacted by reduced project activity due to a slowdown in the PRC economy SHENZHEN, China, Dec. 23, 2025 (GLOBE NEWSWIRE) -- CDT Environmental Technology Investment Holdings Limited (Nasdaq: CDTG) (“CDT”, the “Company”, or “we”), a leading provider of waste treatment systems and services throughout China, today reports its unaudited interim financial results for the six months ended June 30, 2025, and provides updates on key business developments. All amounts are expressed in US dollars unless otherwise stated. 2025 Unaudited Interim Financial Results and Business Update Revenues decreased by approximately $5.4 million, or 42.3%, to approximately $7.3 million for the six months ended June 30, 2025, from approximately $12.7 million for the same period in 2024. The decline was driven by three factors: (i) reduced external demand for the Company’s traditional environmental engineering services amid the PRC economic slowdown; and (ii) the Company’s deliberate strategic shift to scale back on legacy projects with excessively long receivable cycles, reallocating resources toward its new green hydrogen and organic waste-to-energy initiatives. (iii) decrease in the number and timing of project revenue recognitions, as six project contracts contributed revenue during the comparable prior-year period, whereas only four projects contributed revenue during the current period, with certain remaining projects not yet meeting revenue recognition criteria. Among the four projects recognized in the current period, except for the Guankou project phase 6, the other three projects had reached over 95% completion and were in their final stages, resulting in limited incremental revenue recognized during the period. Gross profit decreased by approximately $1.6 million, or 35.1%, to approximately $2.9 million for the six months ended June 30, 2025 from approximately $4.5 million for the six months ended June 30, 2024. The decrease in gross profit is primarily due to a decrease in sewage treatment systems revenue. For the six months ended June 30, 2025 and 2024, our overall gross profit percentage was 39.9% and 35.5%, respectively. The increase in gross profit percentage of 4.4% was primarily due to the following: (i) The approximately 4.8% increase in the gross profit margin of sewage treatment systems was primarily attributable to the Company’s engagement in a new project that generated approximately $3.1 million in revenue with a relatively higher gross profit margin of 40.3%. (ii) This increase was partially offset by a 4.7% decrease in the gross profit margin of sewage treatment services and other revenue, primarily due to higher labor and material costs. Total operating expenses increased by approximately $1.4 million, or 51.9%, to approximately $4.1 million for the six months ended June 30, 2025, from approximately $2.7 million for the same period in 2024. The Company reported a net loss of approximately $1.3 million, or $0.11 per share, for the six months ended June 30, 2025, compared to net income of $1.4 million, or $0.14 per share, for the same period in 2024. The swing from profit to loss was primarily due to: (i) lower revenue from reduced project activity amid weakened market demand; and (ii) the recognition of $2.1 million in non-cash stock-based compensation expense related to the Company’s 2025 Equity Incentive Plan, under which shares were granted to key employees and advisors and accounted for as compensation in accordance with ASC 718. Business Update As of June 30, 2025, the Company had three projects in backlog: the Sichuan Anya Project, the Xinjiang Project, and Phase VI of the Guankou Project. Both the Sichuan Anya and Xinjiang Projects were signed and commenced in August 2024. Phase VI of the Guankou Project is a supplemental agreement to the existing Guankou Project, which was signed and commenced in April 2024, and represents an incremental scope under the original contract—it does not constitute a new, standalone project. The combined tentative contract value of these three projects is approximately $19.6 million. Green Hydrogen Initiative Strategic move into green hydrogen: As announced on November 20, 2025, the Company initiated a new growth opportunity with its shift to become a provider of urban and rural organic waste resource utilization solutions and clean energy. Technology and partnerships: The Company’s plan is to utilize high-temperature gasification technology to convert organic waste into syngas, which can then be purified to produce hydrogen. In May 2025, the Company appointed a senior expert from the Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, as Chief Scientist for the Company’s new energy initiative, establishing a technical collaboration with the Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences. Addressing market demand: The initiative aims to capitalize on the significant demand for organic waste treatment in China and the rapidly growing hydrogen energy market. Diversified revenue streams: The Company’s new “EPC engineering + long-term operation” business model includes revenue from waste treatment fees as well as expected future sales of energy products like green hydrogen, clean industrial steam, and grid-connected electricity. Li Yunwu, CEO of CDT, said “Our first half 2025 performance was challenging as we continued to experience economic headwinds in the PRC market that have impacted new infrastructure projects and delayed some that are in the pipeline. Despite these challenges and the resulting volume pressure, we achieved 250 basis points of gross profit margin expansion compared to the same period last year through the restructuring initiatives we undertook in 2024 and other cost-saving measures. As economic conditions in China stabilize, we believe we remain well positioned to capitalize on opportunities associated with favorable, long-term secular trends including water conservation, safety and regulation. Mr. Li added, “Even as we face an unpredictable operating environment in the near-term with soft end market demand, we are taking proactive and strategically targeted steps to leverage our core operational capabilities through technological innovation and partnerships. Our recently announced strategic initiative to support the growth of the hydrogen economy is an integral part of our planned transformation and broader strategy to participate in new energy by commercializing operations of organic solid waste-to-hydrogen production facilities in China. We believe our collaborations with leading scientific organizations and government regulatory bodies have created a foundation for the Company to accelerate the transition to a hydrogen economy. We expect to report several milestones related to our green hydrogen initiative including advancements in the Company’s hydrogen enabling technologies, as well as progress in executing several customers’ hydrogen projects and new partnerships in the sector. We believe the actions we have taken to streamline our operations, along with our planned long-term investments in our new energy growth initiatives, are expected to deliver value to customers and improve returns for shareholders.” About CDT Environmental Technology Investment Holdings Limited CDT, headquartered in Shenzhen, China, is a leading national player in China’s waste treatment sector that designs, develops, manufactures, sells, installs, operates and maintains sewage treatment systems and provides sewage treatment services in China, and is dedicated to promoting sustainable development through innovative solutions.
