We continue to expand on our environmental hygiene projects, and we strengthen the extension of our industry chain.

It is a period where the country will have new commitments to the dual carbon targets. In this regard, for the processing of waste-to-energy and also the incineration plus models, this will be a further support and further guide. There are some supporting policies coming out as well in a number of cities and regions. In governance and also in the overall situation, there will be more support, but at the same time, there are challenges as well, such as insufficient volume of waste and also some macro challenges, including stricter regulation. All these are challenges. At the same time, we will increase our capability and in particular in the incineration plus model, we will put in more efforts so that in the WTE projects, we'll continue to develop our downstream projects and also to develop hygiene and environmental related projects so that for WTE, we are able to build a integrated supply or industry chain.

Now, Mr. Yuan will be talking about the performance and business review of the company. Thank you, Chairlady. Let me go through the business review for 2022. For 2022, our processing capacity of operating projects continues to increase. It is already at the tune of 31 projects with 41,890 tons per day. That is an increase of four projects commencing operation. In Zhanjiang, Huidong and Guangxi Baise, these projects have also commenced operation, and they have been successful in their operation. The four projects that have been commenced operation had increased the processing capacity by 6,650 tons per day. At the same time, we enjoy very stable relationship with our co-operators, Shanghai Baoshan, Sichuan Dazhou, and Jiangsu Taixing. Total four projects have also increased our overall operation tons. The total is brought to 41,890 tons per day, with these 31 projects in total. At the same time, we have five projects which are under building. These projects in the next four years, they will be completed at different times. In 2022, our total generation had increased 20% to 5,249,545 units. Our sales had also increased, which is a over 10% increase from last year. The power sold is over 4,500,000 MW. Sales to generation ratio is 86.3%. For segregation of regions, Guangdong Province for 2022 was 33.2% of total. Other provinces, 66.8%. Power sold by regions was Guangdong 32.9%. The rest, 67%, was others. For operating efficiency, it is very high. In terms of the rate between our generation and our sales, it is 80%. The design processing capacity by regions is also very healthy. In the Guangdong Province, the MSW in Guangdong was 36.6%. The rest other provinces. Processing capacity was 36.2% in the Guangdong Province. Utilization rate of WTE plants was 104.9%. The design processing capacity as well as the processed MSW had risen healthily. We continue to expand nationwide. We have established WTE in 12 provinces and municipalities across the nation. We will continue to expand to contribute to the industry. On the other hand, there are challenges, for example, a lack of volume of waste. That is another issue. With the regulations being stricter, that is another challenge that we will face. We will be going into other sectors and reach out so as to provide more generators for our growth. We will have a whole industry chain development, including in transport of waste and also in other series of areas. We will be moving downstream and also upstream so that there is synergistic effect for our company. These will include [fat] and waste treatment and also other integrated environmental hygiene services. We continue to increase our efficiency, and we have already set up a team to develop our business. We will continue to increase our competitiveness and to lower our costs and also increase our productivity so that we will keep ourselves at a high level of operation. We will optimize our costs and also increase our efficiency. With our capabilities in management and building up new projects, we will continue to be steadfast in expanding our business and to develop our digitalized management and also adopt innovation and novel technology so as to lower our emissions of our projects and also increase our market competitiveness. In the end, go for even more higher and more stable operation and results. Next, we will have the CFO speak to us about the financials. Ladies and gentlemen, let me review for you the 2022 financials. Even though 2022, overall speaking, has been challenging, but on the other hand, our group has sustained a increase in terms of our operation results. Revenue has increased 21.4% to HKD 8,000 million. At the same time, our gross profit has also increased because of various sectors of increase. 19.8% increase to HKD 2,529 million in terms of gross profit, and gross profit margin was 30.7%. Profit attributable to equity holders of the company had increased by 0.8% on the basis of 2.21 to HKD 1,332.8 million. Profit attributable to equity holders of the company margin was 16.2%. Mainly the U.S. dollar and the RMB devaluation, the exchange rate of them has provided challenge of the company and the macro environment challenges that I have and other colleagues have mentioned just now. Whole basic earnings per share was up 0.9% to HKD 0.549. Revenue analysis for the business sector. First of all, revenue from power sales and waste treatment fees was an increase of 16.3% to HKD 3,486.7 million. This is because of increase and enhancement of efficiency and productivity of our projects. Also, we can see that the waste volume and generation volume had both increased by over 20%. There is a 35.8% of environmental hygiene and other services income to HKD 227 million. For revenue from project construction services, that had increased as well because of services in the municipalities and the cities, the increase had been 24% and will continue to grow this services segment to HKD 4,361 million. In 2021, we have a number of projects which have commenced operation, and in 2022, they have been completed and come onto stream in terms of revenues. For finance income from service concession arrangements, it was 49.8% up to HKD 172 million. Let's look at the gross profit analysis of the business sector. For power sales and waste treatment operation, it was an year-on-year growth of 7.9%. Power sales and waste treatment operation was a 46.3%. It is close to 63% in terms of contributions. That basically because of the growth in terms of our capacity. For gross profit margin, with the 46.3%, it is slightly lower by 3.6%. It is because for the 2022, newly commenced projects have been more numerous than 2021, and therefore it has pulled down the gross profit margin as well as some challenges in the year that have been mentioned. We will continue to raise efficiency and productivity of these projects. Our gross profit margin in terms of power sales and waste treatment operation has been at par with the past year, and it stands at 46.3%. Gross profit margin by business sector is 21.9% for project construction services and about 71% for power sales and waste treatment operation. Gross profit analysis by business sector in 2022 is 63.8% for power sales and also 26.3% for project construction services. last year, the end of last year, the gearing ratio was, end of 2022, it stood at net debt to equity ratio, 130.7%, and gearing ratio was increased to 65.1% from 63.6%. Total assets had increased by 5.6% to HKD 25,820 million. Cash generated from operating projects had increased 25% to HKD 2,000 million plus. For CapEx, we think that even though the projects have been coming onto stream and have been bringing on healthy cash flow for the company, but at the same time, we see that our cash has been healthy, and the cash outflow has been improving as well. At the same time, for our gearing, we are, it is under control. We are prudent in our approach. With diversified sources of funding and resources, we lower our cost of financing. We believe that in 2022, we will be lowering our gearing ratio continuously. During this period, CapEx had been an increase of 14.7% to HKD 3,904 million. It was happening mostly in the first half of 2022. Return on equity was 15.5%, and this is because profit had increased for the group. For future development plans and in 2022, we will continue to hold stable our payout ratio for dividend, which was 20%. It amounted to HKD 0.109 in terms of payout.
