I am doing a project oon f "Stock Valuation" where we select a company and do the stock valuation analysis for upcoming 7 years.

I was following professors instruction solving this, but at the ending part, some of my values started getting negative in value.

Current Enteprise Value is negative and the final Stock price is also negative (-48.929504) Can it be negative? Did I make any error or mistake on any part or my calculation is correct?

P.s forumula I used in Stock Price is =(B72-B74)/B75
