Drugstore chain Walgreen Co. ( WAG ) reported fourth fiscal quarter 2013 earnings on Oct. 1 that were mostly in line with analyst estimates, who had correctly surmised the company would continue experiencing healthy growth. The earnings call also included the chain's year-end figures, which saw a slight uptick in revenue but increased profits. In their report, Walgreen cited a 19.1 market share in prescription sales, or .4 percent increase, as a highlight of the year. In the latest quarter, prescriptions made up 63.9 percent of the company's revenue. Last year, Walgreen acquired Swiss-based multinational pharmacy Alliance Boots for $4 billion in cash plus stock. The Alliance Boots acquisition contributed $154 million in equity earnings to Walgreen's coffers this quarter. This beat Walgreen's own expectations of $120-$150 million stemming from that investment.
