I think you should send out as much info as possible the moment you have a booking on the calendar for your presentation—even if it’s months away. Then send something out again a few days before—even if it’s the same content.

The final fear people have is that audiences will complain if the same material is covered in the speech that is covered in the text. Relax; this will not happen. As long as you don’t read the PowerPoint (and you would never do that, right?), then there is no danger of most people even realizing your content is the same. So dump your data on your audience in advance; just don’t do a boring data dump in the middle of your speech.
