Also, it can be extremely helpful to understand what the reaction might be to the information before issuing a broader statement. Share news one on one with a few people to gauge reactions and better understand how they feel about the change. When dealing with nuanced information, these one-on-one conversations are much more effective than an email announcement that can come off as emotionless or insensitive. Ask for feedback: what is clearly understood and what could use more explanation? Most importantly, ask them to keep the news in confidence. Don't delay too long before making a formal announcement, however, because news, especially bad news, can leak fast.
