Public vs. Private M&A

Hi all,

Quick question. What are the primary differences between private and public M&A? In my currently role, I've only dealt with the sale / acquisition of private businesses. For public companies, do you still make teasers, CIMS, MPs, etc.? Given all of the information is public I wasn't sure if an auction is even typical. Similarly, what about a QofE? Is this even needed given all of the financials are public? Lastly, if anybody has input into the nuances of the day-to-day work as an analyst on a public deal I'd be interested in hearing some of the specifics as compared to a private sell-side.
