2. Investment in your company has lost more than 300000 yuan in 9 months. Does your company’s leader have any measures for the continuous decline of the company’s share price

[Zhang abin]: Dear investors, the recent market fluctuations are huge and the company’s share price has fallen a lot. I understand your mood very much.

Thank you for your question! 3. Why does the chairman reduce his holdings again and again? Is he not optimistic about his company or why [Yang Yunchun]: Hello, the management of the company is full of confidence in the future development of the company! 4. Why did Mr. Yang reduce his holdings at a high level precisely, accurately and ruthlessly, and put all the additional shares on it? Why [Yang Yunchun]: in recent years, the price of his reduction has been high and low, which is not necessarily related to the rise and fall of the stock price; The company’s share price has fallen sharply in the past six months for many reasons. The market may be worried about the international situation, epidemic situation and semiconductor industry cycle, but the company’s operation is normal and is making efforts to develop in accordance with the established strategy. Thank you! 5. Do you know what is “cautious in words and deeds”? Do you know what “devote yourself to practice”? Speak human words, do dog business, open your mouth, and spray out any heroic words. Have you considered the actual situation? Have you ever calculated carefully? Every day, the wheels say it again and again. I don’t know what’s wrong with the company? It’s in the hands of your business people who are obsessed with calculation. Calculate the national large funds, calculation institutions and small and medium-sized investors. The conscience is eaten by the dog! [Zhang abin]: Dear investors, it has taken seven years from planning to acquire overseas high-quality assets to realizing the operation of local production lines. During this period, the company has received long-term and strong support from various investors, including large funds; Today, despite various difficulties and challenges, the company is firmly optimistic about the future development prospect of MEMS and Gan business and has never wavered; You can criticize and dislike the company, but I hope you can also be “cautious in words and deeds” and look at it rationally.

President Yang, the development in the past two years is obvious to all, while the company’s reputation is getting worse and worse. Last year, it was said that there were many filters in the verification process. How many have passed so far? If not, what is the progress so far, and is there a specific time table for completion? [Yang Yunchun]: at present, the development and verification of several products are in progress, and the specific time is hard to say, but I think we can come out one after another this year. We will wait and we will pay close attention to it. 8. Hello, Mr. Yang!

At present, the company’s fixed growth institutions, China Thailand and various institutional funds generally suffered huge losses last year, and the national large funds are close to the cost line. What measures does the company take to enhance investors

Confidence? Is there a repurchase? Or speed up the product validation process? After more than half a year, a large number of products are still being verified? What’s the reason, please say it directly? If it takes several years from development and verification to mass production, the pace of China’s scientific and technological progress will be destroyed in your hands… [Yang Yunchun]: to be honest, your question makes me feel deeply stressed.

Although the share price has fallen sharply, the company and I have been working very hard to develop business in recent years, and I am also full of confidence in the future; However, semiconductor manufacturing has its particularity and objective law, which requires continuous investment of energy and time; I hope investors can be more patient.

Thank you for your question! 18. For Shengyan of the market, Sai Microelectronics Inc(300456) predecessor Neville technology divested the listed company to you due to strategic change.
