As I understand it, the key phrase is "material information". Changing CEO, closing a plant, laying people off, better/worse earnings news, and sales figures are all examples of material information.
What likely happens is the company releases the material information through proper channels and then company representatives use that information as talking points during an interview. Some new information could be given during the interview but it's likely to be minor stuff like specifics on features for a product.
