Your article almost certainly stays, and gets updated rather than deleted. In most cases, Wikipedia's rule is that a company which earned an article by getting real news coverage keeps that article, even after it stops existing as an independent business. Wikipedia's shorthand for this is "notability is not temporary." The only time your article will be merged with the parent is if editors decide the inclusion of your company page was mistaken in the first place.
Instead, what changes is the content.
The acquisition should be reflected in a new addition to the article's history section, the infobox (the box of quick facts at the top right of the article) updated to name your new parent company, and perhaps elsewhere, often within hours of the announcement. Much later, if your brand disappears entirely, news coverage dries up, and editors decide the article about you was premature at the time approved, editors may eventually fold your page into the parent company's article. This at least leaves behind a redirect, which means anyone searching your old name still lands in the right place.
For the acquiring company, the practical meaning is simple: you now have one more article to keep accurate, and the whole family of articles should tell one consistent story.
