You are only reading what you want to read which, in this case, is the negative. If you look at several of my comments, I said that the information you provided does not give any way to rationally, confidently provide you with pricing. The kind of narrative you are suggesting is EXACTLY what I would need to justify pricing. Yes, a 25-year old Company can have positive attributes.
A 25-year history can also be a detriment. But I would not know that by only reading the numbers you gave. If it is 25 years of coin-operated phones, it would be worthless. If it is 25 years of any kind of technology that is potentially on the brink of extinction, it would be worthless. If it is 25 years of selling nothing but Chrysler products, it would be almost worthless. If it is 25 years of one or two people who run the show, are the face of the business, do most of the selling and on whom customers solely rely, it has a VERY low pricing capability. If it is a motel, there could be 25 years of "deferred maintenance", which means the Buyer has to put millions of dollars into the facility to maximize any income, which then erodes your pricing.
That is why earlier I said, "Call me." READ WHAT I WROTE: "I can't answer that, without seeing the entire picture. When you ask these things in the absence of a full picture, you will get a stilted answer. And that can go either for you, or against you." Read that last sentence again, right now. The lack of information can be misleading, and "...can go either for you, or against you."
You stated that, "As a seller, I would expect a business broker to be able to communicate that to a prospective buyer." As a Business Broker, I would expect any Seller with whom I would agree to work, to provide me with honest, complete answers. It is obvious you don't want fact, you want some one who will tell you only what you want to hear. For free.
