II. Communication with Accounting Firm

III. Explanation for the Changes in Results

(1) The overall results of this reporting period decreased significantly compared to the corresponding period last year, mainly due to the changes in performance of the Company's lithium battery materials segment. During the reporting period, the main product of the Company's lithium battery materials was lithium hexafluorophosphate. Although the sales quantity of this product increased year on year, the market price fell significantly over the corresponding period last year due to changes in the supply and demand relationship between upstream and downstream in the short term, resulting in a sharp decline in product sales revenue. On the other hand, the market price of lithium carbonate, the upstream raw material, was high at the end of last year and at the beginning of this reporting period, and the inventory of raw materials at the beginning of the period was also relatively high, resulting in a relatively high overall cost of lithium battery materials during the reporting period. Under the dual impact of lower sales prices and higher costs, the gross margin and gross profit of the Company's lithium battery materials segment in the first half of the year decreased significantly compared to the corresponding period last year. At present, the high-priced raw materials at the beginning of the period have been used up.

(2) The impact of non-recurring gains and losses on net profit during this reporting period is approximately RMB80 million, mainly due to the asset disposal gains generated from the demolition and compensation of the properties owned by two subsidiaries in Shanghai.
