re: M&A gurus, my company has hired consultants for valuation

You can safely assume the owners are interested in selling for the right price but not really anything more than that.

Even if they do sell it may or may not have much impact on you. For example, if you're one of the people doing work that results in more revenue you're probably fine. If you're doing backoffice work (HR, accounting, corporate IT) you might want to at least make sure your network isn't stale but you might be kept on anyway. Or not.
