What are the regulations and precautions for listed subsidiaries to acquire parent companies?

There is no need to dissolve. The simplest thing is to look at the steel industry of A shares a few years ago. For example, several listed companies have merged, such as Hebei Iron and Steel, Shandong Iron and Steel and Panzhihua Iron and Steel. These are all conducted in the form of stock exchanges. After the merger, these companies still exist before the merger. Just look at their financial reports.

Acquisition and merger are the same in a sense in my cognition. Acquisition generally refers to the acquisition of small companies by large companies. Merger generally means that two or more companies are quite large and merged when they are integrated.

As for whether it is better to exchange shares or cash, it depends. Cash purchase often leads to a certain debt cost. You can see that there were many debt acquisitions in the United States in the last century, and most of the acquirers did not have enough cash. However, it should be noted that it was the era of American bond bubble. If cash is abundant, it is certainly good to buy shares in cash, which will not dilute shareholders' rights and interests. The stock exchange merger may dilute shareholders' equity. So, there is nothing better. The key is to look at the actual situation of the company and adapt to local conditions.

When a listed company acquires or merges a listed company, the acquired party does not need to be dissolved. Just look at the case I mentioned in the first paragraph.

Overseas acquisitions and overseas listings are mostly backdoor, and the acquirer is usually a shell company. If there are no assets, it is common for the domestic securities market to buy an empty shell and then carry out asset replacement and rights issue operations.

I guess you're talking about the overall listing. The parent company uses the platform of subsidiary listing to go public as a whole. Generally, the shareholders of the parent company exchange the equity of the parent company for the equity of the subsidiary company.

Whether it is necessary to suspend trading depends on the trading rules of the exchange. In the domestic securities market, the first trading day after the completion of the stock exchange is the resumption of trading, with no ups and downs. (Note that the plan is not announced, but the stock exchange process is completed. )
