No it doesn't. It implies that you don't want people to know about it. But there's plenty of things in business that are legal and ethical, but you still want to keep quiet. For example, Google kept their search revenue quiet for a long time and intentionally did so. Were they doing something wrong? I'm sure Apple would like to keep their supplier deals quiet.
If you're getting a good deal with competitive advantage, you often want to keep that quiet -- and it doesn't imply you're doing anything wrong. Now if they statement ended with, "or we could all up in jail" then that would imply they were doing something wrong. This just sounds like they found a sweet deal and wanted to make sure they could milk it with as little cost for as long as possible.
