Supplementary Announcement on Short-swing Trading of Family Members of a Supervisor of the Company

Ming Yang Smart Energy Group Limited (hereinafter referred to as the ''Company'') released ''Announcement on Short-swing Trading of Family Members of a Supervisor of the Company '' on 21 June 2023, which stated that there had been short-swing dealing in respect of the immediate family members of Mr. Zheng Weili, a Supervisor of the Company. After communicating with the Supervisor himself, he agreed to change method for calculating gains from the short-swing trading:

I. Calculation Method in the Original Announcement

From 29 October 2021 to 21 April 2023, the securities account of Ms. Liao Xiangyan (spouse of Supervisor Zheng Weili) bought 20,500 shares of the Company, totaling RMB569,110, at an average cost of RMB27.76/share; sold 16,500 shares, totaling RMB447,302, at an average cost of RMB27.11/share; after deducting the remaining 4,000 shares of Liao Xiangyan's securities account, the cumulative loss is (27.76-27.11) *16,500 = RMB10,725.

From 28 January 2021 to 7 June 2023, the securities account of Ms. Xu Dafang (mother of Supervisor Zheng Weili) bought 64,700 shares of the Company, totaling RMB1,593,785, at an average cost of RMB24.63/share; sold 55,800 shares, totaling RMB1,361,985, at an average cost of RMB24.41/share; after deducting the remaining 8,900 shares of Xu Dafang's securities account, the cumulative loss is (24.63-24.41) *55,800 = RMB12,276.

II. Changed Calculation Method

In view of the fact that the securities accounts of Ms. Liao Xiangyan and Ms. Xu Dafang were both controlled and operated by Ms. Liao Xiangyan, all the transactions of the above two securities accounts were combined and calculated, and it is determined that the trading period was from 28 January 2021 to 7 June 2023, and on the basis that the highest selling price during the period is matched with the lowest buying price, and the remaining number of shares is matched with the second highest selling price or the second lowest buying price in sequence, the matched selling and buying amounts were RMB1,809,287.00 and RMB1,733,063.00, respectively, resulting in a calculated gain of RMB76,224.00.

III. Subsequent Treatment of the Transaction

In accordance with the changed calculation method, Ms. Liao Xiangyan, a close family member of Mr. Zheng Weili (a Supervisor of the Company), has recently surrendered the aforesaid gains to the Company.

The Board of Directors of the Company will subsequently continue to strengthen the compliance management of Directors, Supervisors, senior management and shareholders holding more than 5% of the Company's shares, and urge relevant persons to supervise their relatives to abide by the rules in order to prevent the recurrence of such incidents.

There is nothing in the PCA notification filed by the Company on 21 June 2023 that needs to be updated pursuant to this announcement.
