All good points so far.
I'd add don't use acronyms unless you're sure your audience understands. I work in an industry that loves its acronyms and it's beyond distracting when they assume we catch the meaning of their financial or other insider type acronyms.
And leave some time for Q&A at the end unless the agenda dictates otherwise, and if so then leave people with a website or email address to use if they would like a follow-up.
Finally, one group I'm in that meets monthly typically asks the speaker to give us an electronic copy of his/her presentation so we can post it for our membership. Some speakers are reluctant because it contains some data or information that they would rather not disseminate to post on the internet. So sometimes they give us a "basic" version of their actual Powerpoint. Just be prepared for that question, and how you'd like to handle it.
