2015 sales: $15.389 billion
2016 sales: $15.724 billion
Their business growth has stopped. In fact, it's that negative turn (in regards to the perception of WFM as a growth machine) that halved their stock, which led to Amazon acquiring them.
To make matters worse for the company, their net income had been contracting for years.
2014: $579m net income
2015: $536m net income
2016: $507m net income
Amazon will hack that down further, basically taking WFM where it was already going as their margins were eroding for years.
But yes, this was a company that found a niche, grew into it and could go elsewhere. Amazon will presumably change that, though in the end I doubt WF will be recognizable.
But that's going to be highly variable by location and who the local competitors are.
