As part of my work in the mergers & acquisitions area, we are building financial models to simulate the future of a business. These simulations are used to assess the purchase price of a business.
In your case, it looks like you are interested in a model with a 3 year plan, showing your anticipated revenue (possibly by division or product line if you have multiple ones), estimated cost and operating income. Looks like you are interested in pre-tax and after tax results. I would encourage you to also show EBITDA, as it is often used by banks in covenants and when they compare businesses inside the same industry. Let me know if you want my help.
