As a person who actually makes those decisions, negotiating contracts and making purchases, I couldn't care less about the other party's stock price. If I have any question about their ability to support a product, honor a warranty, etc, I look at their financials and reputation. The questions I ask myself are: do they have a good reputation with their customers, and can I collect if I have to go after them. Stock price, private vs. public, etc have no bearing whatsoever.
