Net sales fell to $434.1 million from $472.0 million a year before, while the two analysts tracked by FactSet who cover Express’s stock were anticipating $451.8 million on average. Consolidated comparable sales were down 8% in the quarter. “The third quarter was tougher than we anticipated and that is reflected in our results,” Chief Executive Tim Baxter said in a release. “The macroeconomic, consumer and competitive environments were extremely challenging, and became more acute as the quarter progressed.” The company now expects that comparable sales could be flat to up 1% for the full fiscal year.
