"May I bring a couple of things to your attention?" is a polite, generic way to start off any conversation where you intend to share pertinent information.
I would avoid saying "facts" as that may sound a little harsh up front; if the items are factual it will be clear after you present your findings. It is also important to anticipate how the listener may react; you may want some follow-up supporting phrases in your pocket as well.
Are these "things" shocking and/or personal in nature? They may still need to be shared, but remember, you cannot throw a rock in the water gently enough to avoid some ripples. Suggestions on what can be done should be available if asked for by your recipient.
Perhaps the "things" are "wow" factor details regarding business. If so, be prepared with ideas on how to solve or act upon them.
Under any circumstances, if you are going to present a problem or surprising reality, it is always good to have one or two solutions at the ready to soften the blow and avoid extending a potentially awkward situation.
I wish you the best with your writing.
