So imagine you have a lemonade stand and your friend has a toy store. Your friend wants to sell his toy store to the public so they can own a piece of it, but he doesn't want to go through all the complicated paperwork and rules and regulations.
So, he decides to come over to your lemonade stand and give you some of his toy store shares, making you the owner of the toy store. Now, your lemonade stand is technically the toy store and anyone who buys shares in your lemonade stand shares in the toy store.
This is kind of like a reverse takeover. Instead of the toy store buying your lemonade stand to go public, your lemonade stand takes over the toy store and becomes the publicly traded company.
