MAJOR REASONS FOR THE ESTIMATED LOSS IN RESULTS FOR THIS PERIOD

In 2023, as the domestic economy continued to recover and multiple unfavourable impacts gradually receded, the Company grasped the market opportunities, proactively enhanced the level of capacity, seized the hot markets, strengthened lean management and control on costs, and accelerated and optimized the utilization of idle assets, resulting in a significant year-on-year reduction in loss of operating efficiency. However, due to a number of factors such as the relatively slow recovery of international passenger flights, the overall oversupply of domestic passenger transportation, the high level of oil prices, the impact of the strategic investment of Sichuan Airlines, the significant increase in the prices of aircraft and aviation materials due to the global supply chain disruptions as well as the depreciation of the Renminbi, the Company is still facing greater operating pressure and the Company expects to record a loss in the operating results for the year of 2023.

IV.

RISK WARNINGS

The finance department of the Company is making every effort to prepare the financial statements for the year of 2023. In respect of this estimated results, there is no substantial uncertainty which may affect its accuracy.
