Walgreen Company (NYSE: WAG) reported earnings for the second quarter on Monday. Net sales grew by a very decent 10%. Diluted earnings per share for the quarter were $0.69 versus $0.65 in the year-ago period; this represents a bottom-line gain of 6%.

Considering some of the other action on Wall Street on Monday -- the increased offer for Bear Stearns, the approval of the Sirius/XM merger -- Walgreen's earnings report was simply an okay event, even though the stock closed up around 5% on the news. Same-store sales may have increased 4.7%, but the retailer sold a lot of items with lower margins this time around, thus reducing its gross-margin metric by 14 basis points (the release did cite a big shift to pharmacy sales in the quarter as having negatively impacted margins). So Walgreen needs to work on its non-pharmacy revenues. One cool thing from the report is the jump in net cash from operations -- that number increased by 10%.

Walgreen, which competes with CVS Caremark Corporation (NYSE: CVS) and Rite Aid Corporation (NYSE: RAD), isn't a bad way to play the long-term drug-retailing business. To be sure, baby boomers -- as well as everyone else -- will always need to visit drugstores on a go-forward basis. It's the company that can capture a significant amount of non-pharmacy sales that will prosper the most. Walgreen and CVS are excellent brand names in this sector -- I'm not so keen on Rite Aid, though (take a look at the stock price and see if you think the company might be cheap-for-a-reason, as they say).
