(3) Analysis of evaluation conclusion and selection of evaluation results

The income method is greatly affected by the future profitability, asset quality, business ability and business risk of the enterprise. In this appraisal, as the energy storage industry of the appraised unit is still in the early stage of development, the influence of policy factors makes it difficult to accurately predict the medium and long-term profits of the appraised unit in the future, and it is difficult to accurately measure the medium and long-term business risks of the appraised unit in the future due to the accelerated iteration of industrial technology renewal. Therefore, The availability and reliability of the forecast data of the income method are relatively insufficient, and the application of the income method in this appraisal is actually limited to a certain extent.

The asset based method reflects the fair market value of the assets from the perspective of asset replacement. In combination with the current appraisal, the appraised unit has provided detailed information about its assets and liabilities, and the appraisers have also collected information from outside to meet the requirements of the asset based method. We conduct a comprehensive inventory and appraisal of the assets and liabilities of the appraised unit. Therefore, relatively speaking, The appraisal result of asset-based method is relatively reliable, so the appraisal result of asset-based method is taken as the final appraisal conclusion. To sum up, the appraisal result of the asset-based method is taken as the appraisal conclusion of the appraisal report, that is, the market value of all shareholders’ equity of the appraised unit on the benchmark date of December 31, 2021 is RMB 69.9646 million (in words: RMB sixty-nine million nine hundred and sixty-four thousand and six hundred).

9、 Validity period of asset appraisal conclusion: the asset appraisal conclusion is valid only on the benchmark date specified in the appraisal report. The appraisal conclusion is valid within one year from the benchmark date (i.e. December 31, 2021 to December 30, 2022). If it is more than one year, it is necessary to re evaluate the assets. 10、 Special notes:

1. The three energy storage battery compartments under the subject of fixed assets – machinery and equipment of the appraised unit were obtained through financial leasing, and the actual property right still belongs to the financial lessor. As of the benchmark date of appraisal, the total book value of the three energy storage battery compartments is 108.6 million yuan.

Please pay attention to the impact of the above special matters on the appraisal value.

11、 Application scope of evaluation report:

1. User of the assets appraisal report: the client;

2. Other users of the assets appraisal report: functional departments and relevant parties related to the purpose of the appraisal as stipulated by laws and administrative regulations;

3. The economic behavior and appraisal purpose stated in the asset appraisal report.
