Earnings Preview: Pfizer Expected to Post Lower but Inline Results

Pfizer (PFE), the maker of erectile dysfunction pill Viagra and the cholesterol fighter Lipitor, is expected to report lower quarterly earnings Wednesday (on an adjusted basis) than it did a year ago, even as it reports the combined results following its $68 billion acquisition of Wyeth, which it completed during the quarter. Following a quarter that saw both setbacks and good news for the company, what investors will want to know is how Pfizer's restructuring and diversification strategies are working out.
