We'd like to hand over the time to Ms. Loretta Lee, the chairlady, please. Investor, analyst, good afternoon. Thank you all for taking the time to attend the Canvest Environmental Protection's annual result conference today. We are very pleased to have the opportunity to meet with you. At this conference, our CEO, Mr. Yuan Guozhen will report to you on the group's operational situation for the full year of 2023. Afterward, our CFO, Ms. Wong Ling Fong will review the group's financial performance for the full year of 2023 as well. Finally, we'll answer your questions you may have. In 2023, the global situation is intricate and complex. The domestic and international economic environment is filled with uncertainties. We face significant downward pressure. This is also compounded by the fact that continuing interest rate hikes in Europe and America, as well as the persistent fluctuations in currency exchange rate, presenting certain challenges to business environment for companies. Affected by substantial increase in interest rates, which leads to a 10% rise in interest expenses and roughly 7% of depreciations of RMB, the company's profit performance has declined. However, the overall operations of the company remain stable, demonstrating our strong resilience. As the majority of the projects have commenced operations, the group has transitioned from the construction phase to operation phase. The income from construction service generated by project construction has decreased by nearly 70%, making the group's financial performance slightly below expectation. However, at the same time, the group has further strengthened the operational management of existing project, optimized cost structures and enhanced efficiency, entering into a new phase of high-quality operations. Despite the challenges of increasing competitions in the industry, the overall efficiency of the group has significantly improved in 2023. During the year, the group's gross profit margin, EBITDA margin, and net profit margins all increased, reflecting an improvement in the quality of the group's profit. Additionally, as most of the projects of the group have been successfully commissioned, the operating cash flow has turned positive and the debt-to-asset ratio has decreased, indicating that the group's future will be more stable and solid. In terms of business operation, Canvest has leveraged the advantage of waste incineration to actively promote the development of the entire solid waste industry chain and achieved multiple breakthroughs in sanitation services. Scale breakthrough. Canvest won the bid for the Hebei Quyang County Urban and Rural Sanitation project, with a contract amount exceeding RMB 3 billion for the first time. A market breakthrough. For the first time, Canvest secure a RMB 2.8 billion project for waste transfer project in Hong Kong, laying a solid foundation for expanding solid waste business in Hong Kong, regional breakthroughs as well. Canvest enter the sanitation sector in Anhui province for the first time, winning a bid in January for urban butler service project worth approximately RMB 1.8 billion. The above project is long-term and large-scale, reflecting the government's recognitions on the quality operations of our business. Canvest is also actively promoting carbon trading. An incineration project has been successfully registered on the Verified Carbon Standard platform, laying the foundation for the activation of carbon asset in the future. In terms of ESG, our continued effort in environmental protection and community engagement have been fully recognized by the market. In both MSCI ESG rating and Sustainalytics ESG risk ratings, the group has achieved excellent performance. The group was once again selected in the All-Asia Executive Team of 2023 by the authoritative financial magazine Institutional Investor as the most honored company, utilities and alternative energy. Additionally, we are recognized by BOCHK Corporate Low-Carbon Environmental Leadership Awards. We received Bronze Award for EcoChallenger.

In the 15th annual Solid Waste Company Awards and ranked 16th in the 2023 top 50 environmental enterprise in China. Looking to the future, the group will strengthen the operations of existing projects to reduce cost and improve efficiency, will expand sources of waste through multiple channels to meet production capacity needs. We're carrying out collaborative disposal of industrial solid waste and kitchen waste. We'll also develop new revenue growth points and supplied heat. We'll also advance the development of the whole industry chain in environmental protection industry and achieve synergistic development, vigorously develop integrated sanitation, landfill remediations, and we'll carry out regional expansions, forming a good pattern of complementary advantages. We'll also position ourselves in smart environmental protection field and expand the application scenarios of technologies. We'll promote rapid development of smart sanitation and support efficiency upgrade of our environmental operations. By doing so, we seek to improve and upgrade our development and explore new business profit. Now, I'll hand over to Miss Yuan Guozhen to talk about our business review. Thank you, Chairlady. Coming up, I will talk about the company's business review in 2023. As of 2023, the company has signed a total of 36 WTE project with a daily waste processing capacity reaching 54,540 tons. During the period, our projects in Yi County and Huizhou have commenced operation, adding a capacity of 800 tons and 1,000 tons respectively. The total number of operational projects have increased to 33, total operational capacity of 42,690 tons. Now, we have three plant project, Huidong, 1,500 tons, Baise, 1,200 tons and Quyang, 1,050 tons. Over the course of the year, the group's WTE business has remained relatively stable, with projects being commissioned in an orderly manner and capacity continuing to grow. Next, I would like to share about our operational status. In 2023, as most of the project of the group have been successfully commissioned, our operational indicators have continuously improved. In 2023, we have treated about 16.62 million tons of waste, an increase of 18.7% year-on-year. We have generated 6.22 billion kWh of energy, an increase of 18.4% year-on-year. Saving standard coal, 1.62 million tons, up by 17.5%, offsetting carbon dioxide equivalent of 8.6 million tons. During the year, our operational efficiency remains robust. Total power sales reached 5.35 billion kWh, an increase of 18% year-on-year. Electricity generated per ton of waste was about 300 kW h. The project efficiency remains high with good productivity and operational efficiency. The average utilization rate reached 107%, with average sales to generation ratio reaching 86%. The internal power consumption ratio was at 14%, which is below the industry average of 15%, particularly for the project with regional advantages in Guangdong province. As of today, of the 36 project, a total of 17 are located in Guangdong, accounting for approximately 49.1% of the group's total contracted volume. Guangdong province remains the main market for us. As the WTE business is steadily developed, the group develops along the whole solid waste industry chain and deepening our environmental sanitation services. By leveraging integrated environmental sanitation services, including waste collection, transfer, hazardous waste treatment, and landfill remediation. We coordinate with our WTE business, strengthening the integration of industrial chain that combines incineration with environmental business. By providing green and innovative comprehensive services, we seize the opportunities brought by the industry. In 2023, the environmental segment operates 30 projects and five landfill projects. As of today, this segment has secure new contract amount exceeding RMB 8 billion, fully reflecting the group's strengths and competitive advantage in the solid waste industrial chain. In terms of downstream operations, we process about 147,000 tons of solidified fly ash within the year. Leveraging our leading market position in WTE and environmental services, the company has also developed integrated smart city management services. We offered intelligent parking solutions in Guangdong, Hebei, and Chongqing and other locations. We manage over 47,000 parking slots. We achieved several significant breakthroughs in environmental sanitation services. A scale breakthrough, winning a RMB 3.2 billion urban and rural environmental sanitation project in Quyang County, Hebei. Of course, we have market breakthrough. For the first time, we successfully bid for a waste transfer project in Hong Kong market. We'll start commission in March this year, laying a solid foundation for expanding into Hong Kong. The third breakthrough, it's a regional breakthrough. First, we entered Anhui Province environmental hygiene field for the first time with winning a bid of about RMB 1.8 billion. Canvest has achieved very significant milestones in deepening the development of environmental sanitation field and will continue to explore into new areas. Coming forward, we will have Ms. Wong to talk about financial review. Thank you, Mr. Yuan. Hello. I will talk about the financial performance of the company for the full year of 2023. Our total revenue has achieved RMB 4.98 billion, fell by 39.6%. It was mainly due to the fact that we have construction phase and now we have started operation, which resulted in a 76.7% year-on-year decrease in construction revenue. This also resulted in the decrease of gross margin. The decrease in gross profit and the decrease in revenue, that reflects that the group's higher gross margin project operating income has partially offset the decline in construction revenue. It also reflect an improving quality of project. Our generation of power and waste treatment are still improving. Our operating profit can be reflected by the fact that our EBITDA decrease was also less than our revenue decrease. Our profit decreased by 24.9% to RMB 1.02 billion, primarily due to significant increase in interest rate and depreciation of RMB. GP margin and NP margin have improved significantly, which reflect that the reduction of construction revenue. If we look at different segment, this is the analysis. When calculated in RMB, in 2023, the revenue from power sales and waste treatments increased by 5.8% to RMB 3.08 billion, accounting for 68.9% of total revenue. The revenue from environmental sanitation and other services saw a significant increase of 62% to RMB 310 million, representing a 6.9% of total revenue. This include integrated sanitation services, including waste collection, transfer, fly ash treatment, and landfill remediations. We continue to improve. As our project having been successfully put into operation, our project construction service revenue decreased by 74.9% year-on-year to RMB 920 million. Compared to the group's gross profit reached RMB 2,079.5 million, a decrease of 17.8%. A result of decrease in the construction services. The decrease of our gross profit only decreased by 11.6% and our business continue to grow. The Gross Profit margin has improved from 30.7% of 2022 to 41.8% of 2023. This increase has been the result of improving result of our operational income and the WTE business GP margin increased from 46.3%- 46.6%, reflecting a good result of cost control. In terms of asset, you can see that our general asset has been stable and robust. Our gearing ratio has been down to 64.3% and the net debt to asset ratio has also reduced. At the same time, after the construction period, our CapEx has reduced to RMB 1.5 billion. The operational income has turned positive. We have over RMB 1 billion of operating income. As the market turned saturation, we have turned from incremental market to existing market. We've also added a diversified income revenue. We have landfill remediations and sanitation hygiene business. Despite the fact that construction service has reduced, our general revenue has maintained stable and the asset has increased to RMB 20 billion. Our business remain robust and the equity return has decreased a little bit. However, despite that, we maintained a dividend payout ratio of 20%. In the future, we'll continue to improve the investment of the whole industry chain to improve and balance our revenue mix and to continue to improve the stableness of our income. This is my presentation. Thank you very much.
