I'm looking at a business in the food manufacturing space, the majority of their sales come from their own retail locations. I'm liking what I see in this business, but one thing that I'm mulling over is the company's limited operating history. It has been operating for 3 years. The revenues have been stable/growing in that time, and company has been profitable each year. How concerned should I be, and what can I do to ensure that the business is durable?
