I’ll note for the audience that such meetings are common for many types of prosecutions, even for relatively low level criminal ones. If you’ve every watched a TV show about a murder investigation, you know the police will talk to you and get your statement before they arrest you. The SEC will also send a “we’re thinking of suing you” letter (Wells notice), where you can respond with a PowerPoint presentation of “why you shouldn’t sue me.” When you’ve got complex antitrust and securities issues, that up-front discussion becomes even more important.
TV shows are notoriously bad sources of information about the real world. In the real world if the police has anything solid which they believe points at you as the perp, they will arrest you first (possibly after watching you for a while). Extracting information from you is so much easier when you are intimidated and fearful - as anyone would be after marinating for a few days in a cell.
