Our aggregate sales generated from our top five customer groups amounted to approximately 88.4%, 80.6% and 68.1% of our revenue for the financial years ended December 31, 2020, 2021 and 2022, respectively. In particular, sales to our largest customer group, which is principally engaged in the manufacture of HDD, amounted to approximately $13.2 million, S$4.8 million and S$4.1 million, representing approximately 61.5%, 32.7% and 22.0% of our revenue, for the financial years ended December 31, 2020, 2021 and 2022, respectively. Accordingly, our sales would be significantly affected by changes in our relationship with or in the needs of our major customer groups, particularly our largest customer group, as well as other factors that may affect their purchases from us, many of which are beyond our control. Any adverse changes in the economic conditions in the markets in which our customer groups operate and in their business expansion plans may negatively affect their purchasing practices and result in a reduction in demand for our products and services. Furthermore, we have a limited number of customer groups for both our sale of cleaning systems and other equipment business and our centralized dishwashing and general cleaning services business. We sold cleaning systems and other equipment to 14, 11 and 14 customer groups during the financial years ended December 31, 2020, 2021 and 2022, respectively. Our centralized dishwashing services and general cleaning services business provided centralized dishwashing services to 38, 54 and 60 customer groups during the financial years ended December 31, 2020, 2021 and 2022, respectively, and provided general cleaning services to 7, 7, and 3 customer groups, respectively, during those periods. If our major customer groups do not place their new orders with us, our business, financial condition, results of operations and prospects could be materially and adversely affected. In addition to maintaining and growing our business with existing customers, the success of our business also depends on our ability to attract new customers. If we are unable to attract new customers, our business growth will be hampered and our business, financial condition, results of operations and prospects may be materially and adversely affected.
