Don't confuse yourself or the customer.
It goes back to your objective of the meeting. Different objectives may set different way and intonation of discussion. If your objective is to sell the solution, you may need to prepare the relevant sales kit. If you set the right expectation, it will be much easier for you to navigate the discussion.

For meeting senior executives, it is always good to know the company information, his profile, who is he in the company, what he have done or future projects.. but as our friend Jacob said.. Don't be intimidated by him or his position.

Cheers
