Wikipedia's volunteer editors do, and they decide based on one question: has the subsidiary received significant news coverage under its own name? Its position in your org chart has no impact on whether a subsidiary company or brand gets a page.
A subsidiary that generates press about its growth, development, and performance, can support its own article. Even better if the company has some history which has been previously reported. A subsidiary that only ever appears as a line in the parent company's earnings will never rate a page, and a brand with minimal coverage probably rates a mention on your article, not one of its own. If you try, it will probably get deleted or turned into a redirect (a pointer that sends readers to the parent company's article instead.) The logic also runs in reverse: editors sometimes create an article about a subsidiary the company would prefer to keep low-profile, and if the coverage exists, the article stays.
For companies with several notable subsidiaries, the real work is consistency: the parent article, the subsidiary articles, and the quick-facts boxes on each should agree about who owns what, and after any restructuring they frequently do not, because different volunteers update different articles at different times.
