Legal basis: Article 75 of the Company Law of People's Republic of China (PRC), 1. The company does not pay dividends for a long time. Refers to the company's undistributed profits for five consecutive years, and these five consecutive years of profits meet the dividend conditions stipulated in Article 167 of the Company Law. 2. Merger, division and transfer of major property of the company. Among them, "main property" can be identified from three angles, one is to look at the proportion of the value of the transferred property to the company's net assets, the other is to look at the importance of the transferred property to the company's business, and the third is to look at whether the company's articles of association stipulate that the transfer of property requires 2/3 voting rights. The company extended its life. When the business term stipulated in the Articles of Association expires, the cause of dissolution arises, and the shareholders' meeting adopts a resolution to make the company survive. As long as any of the above three situations occurs in the company, shareholders may request to withdraw their shares if they object to the corresponding resolutions of the shareholders' meeting. But the withdrawal of shares by joint-stock companies is different. See Article 143 of the Company Law for details. Another expression of this question is "Can a company buy back the shares of its shareholders?"? In principle, it can't, because it is equivalent to shareholders withdrawing their capital contribution, which will reduce the company's capital and violate the principle of "capital unchanged".
