I am not sure which country you are in and whether you have any protocols in your society and also your own company around meetings with management. The first step might be to find out from someone else who has been in your position what they did and how it went. They may have some useful tips to help you.
Generally though, it is helpful to remember that managers want to hear information at their level. They are busy and need enough information to be able to make a sound decision. Always put your information in the context of the bigger picture (ie a strategic view). So start by introducing your topic, idea or information, and then show how it relates to your company's goals. From there be clear about what you require from the people at the meeting - eg consideration of the topic, to pass the information on to their teams or to make a decision etc. Then give them the information you have as professionally as you can. Again, you need to check out their expectations - do they have a preferred format?, do they like a written document?, do they like power point?, etc.
Try to allow time for them to ask questions at the end.
All the best with your meeting.
