More than you might predict, and none of them happen automatically. Among the places on Wikipedia that may need to be updated: the infobox on your company's article (the quick-facts box that names the top executive), possibly the article text, the outgoing CEO's biography if they have one, the incoming CEO's biography if they have one, and Wikidata, the background database that feeds Google's information panels and many AI tools.
It is common for the company article to name the new CEO while the others lag for weeks, which is why searches and AI assistants sometimes name the wrong CEO long after a transition. Once the announcement is public, submit each update through Wikipedia's official process, a suggested change posted on the article's talk page with your company connection stated and a news story attached, then check every surface again a month later.
How much gets written about the change depends on coverage. If there was intrigue surrounding the departure, your article may describe it however news sources describe it. If the transition was routine and generated little coverage, there may be no mention of it on your page at all; the only change will be the name in the infobox. Expect the outgoing CEO's biography to say a little more, since in the vast majority of cases this is a bigger event in their personal history than it is in your brand history.
As for the incoming CEO: whether they get a biography is not your call to make. Becoming CEO of a notable company does not by itself earn an article. As always, press coverage does, and it must be coverage that is at least as much about them as it is the company.
