Walgreen Does It Again

Walgreen (NYSE: WAG) same-store sales (SSS) rose 5.1% in June. SSS are a key measure for retailers. Total sales can grow by merely opening new stores, but SSS measures growth at existing locations. Broken down, front-end sales increased 6.8%, and pharmacy sales grew 4.2%. This is important news since front-end sales typically have higher margins than pharmaceuticals. Basically, front-end sales are everything but prescriptions, and include items such as health and beauty products.

Walgreen continues to post strong year-over-year comparisons. Last June, Walgreen's SSS rose 9%, with pharmacy sales up 11.6%. Having one fewer Thursday and one more Saturday during the month compared to a year ago, management estimated that pharmacy SSS would have been 1.7% higher. While the 2.3% SSS increase for Rite Aid (NYSE: RAD) last quarter was good, this was compared to a very weak negative 0.3% from a year earlier.

Walgreen operates in a competitive industry. Competitors include other drugstore chains like CVS (NYSE: CVS), mail-order prescription providers like Medco Health Solutions (NYSE: MHS) and Express Scripts (Nasdaq: ESRX), and mass merchants like Wal-Mart (NYSE: WMT). However, Walgreen manages to distinguish itself by expanding into prime locations and making investments in technology and customer service. Front-end sales have continued to grow by staying ahead of the curve, entering new businesses such as digital photo services.

The company continues to impress, posting positive same-store sales results month after month. At a P/E of 21, I don't find the stock rich, given the solid performance that the company delivers.
