How do the shareholders of the original unlisted company (non-shell company) profit from backdoor listing (note that it is not IPO listing)?

The shareholder of the original company (non-shell company) obtained the equity of the shell company through backdoor listing, and after injecting assets into the shell company, he invested in the shell company assets he had previously held (need to be evaluated. If the appraisal price is 200 million, according to the issue price of 5 yuan per share, you can hold the newly issued share capital of Shell Company of 40 million). As shell companies have new assets, profits will definitely rise, so the stock price will definitely go online. At this time, both the old shareholders and the new shareholders of the shell company (the shareholders of the asset injection company) hold the shares of the shell company. After a period of time, usually a lock-up period of 1-3 years, new shareholders can sell their shares, so that they can withdraw at a profit.
