It can happen within hours, but if it doesn't… then it might need some help. Wikipedia editing activity tends to be driven by what is in the news; a common Wikipedian workflow is for an editor to read a news story, wonder what Wikipedia has to say about it, then adding new information with that source as a citation. Some very well-known companies have watchers who update them the same day. But not every company is so closely-watched, and not all pages will be updated immediately.
Let's say a volunteer does add something on their own. The initial version is written by whoever gets there first, citing whatever coverage exists in that moment, which early in a news cycle can mean a thin wire story or a headline that framed the deal differently than you would. If you want to offer a correction or suggest an adjustment, you'll have to go through the proper channel: a message posted on the article's talk page (the discussion page attached to every article), with your company affiliation stated and a good source attached, for a volunteer editor to review. Wikipedia calls this an edit request. What you should absolutely not do as an employee or contractor associated with a party to the acquisition is sneakily rewrite the article yourself, which is likely to catch editors' attention..
Teams that handle this well put Wikipedia on the announcement checklist: know what the article says the day before, watch it the day of, and have sources ready for any corrections.
