Well, Hank Pym is rumored to show up meeting with Radioactive Man in the post-credits scene of Iron Man 3. And ULTIMO already appeared in the Iron Man 2 video game, and seeing as it isn't in contradiction with the movies, it's canon...

I did hear a rumor a long while ago that the Ant-Man film would have two sections, one with Hank Pym in the 1970s and one with Scott Lang in modern times. But Hank Pym is too important a character to leave out of the modern storyline. Though Kevin Feige did confirm that the scientist Erik Selvig mentions in Thor is Hank Pym. It's all a bit confusing, but I hope Edgar Wright realized that having no Hank Pym in the present storyline is bad.
