This is a great question to ask yourself after you finished designing the presentation.
“Well, what I really want is raising a bit of extra equity to de-leverage the company (slide 12, yellow bars). I think it is a really good deal for investors, since it looks like the stock is undervalued (slide 24, bottom right). Management has delivered on all its promises over the past 5 years (slide 15) and no one in the industry has a scale that is even closely to ours (slide 37 on the left), so it looks like our advantage will hold out for the foreseeable future.”
Your presentation can be shorter: focussed slides upfront, with extra info in the appendix.
