Nanjing Sample Technology Company Limited provided earnings guidance for the year ended 31 December 2022. The Group expects to record an increase in net loss attributable to shareholders of the parent company for the year ended 31 December 2022 to approximately RMB 170 million to RMB 280 million as compared with the net loss attributable to shareholders of the parent company of RMB 59 million for the corresponding period of last year. Such increase in loss was primarily attributable to: 1) the increase of provision for impairment losses in 2022 as compared to that of the same period last year.

It is expected that the amount of provision for impairment losses for 2022 will be in a range between RMB 150 million and RMB 180 million; 2) the adverse impact of external factors such as the novel coronavirus pandemic (COVID-19), shrinking market demand and intensified industry competition in 2022 which attributed to a negative impact on the Group's operations and led to decreases of the revenue and gross profit margin of the Group. It is expected that the revenue of the Group for the year of 2022 will decrease by about 35%-45% as compared to that of 2021.
