Discussion: How do the circulating shareholders of the original parent company get benefits after the spin-off?

Companies in the City may benefit from different spin-off and listing plans, and investors may benefit in different ways and scales. For example, Company A will spin off its business or its subsidiary B will go public. One scheme is that Company A distributes the equity of Company B to the shareholders of Company A in proportion. That is to say, after the spin-off, the number of shares held by A-share investors remains unchanged, and at the same time, a certain number of shares of Company B are allocated according to the shareholding ratio of Company A, and Company A no longer holds Company B, and the two become brother companies. In this way, the investor's income is more direct, and at the same time, due to the premium of company B's share price, the income may be greater. Another scheme is that Company A will take out its business or subsidiary B to re-establish a joint-stock company for listing, and Company A will still hold Company B and maintain the parent-subsidiary relationship. The shareholders of Company A hold the same number of shares of Company A, but they can't distribute the shares of Company B. However, due to the listing premium of Company B, the intrinsic value of Company A has been greatly improved, and investors will benefit from the rise of Company A's share price.
