Forest Laboratories (FRX Quote - Cramer on FRX - Stock Picks) is entering this quarterly earnings season with a dilemma common to its brand-name peers -- what to do about the threat of generic competition.
The difference is that the impact could be quite uncommon if Forest loses a patent fight for the antidepressant Lexapro, which accounted for $1.87 billion, or 63% of its corporate revenue, for the fiscal year ended March 31. New York-based Forest is being challenged by Israel's Teva Pharmaceutical Industries (TEVA Quote - Cramer on TEVA - Stock Picks), which wants to break Lexapro's U.S. patent. A trial was held in March, and a judge's decision is expected this summer, perhaps even this month. There's plenty of nervousness because Lexapro's impact on Forest is far greater than what, for example, the cholesterol drug Lipitor provides to Pfizer(PFE Quote - Cramer on PFE - Stock Picks) or the antipsychotic Zyprexa contributes to Eli Lilly(LLY Quote - Cramer on LLY - Stock Picks). Shares of those two companies were rattled when generic-drug companies tried to overturn their U.S. patents, but Big Pharma investors rejoiced when Lilly won a court fight in April 2005 and Pfizer prevailed last December. "We believe the overhang of the [Lexapro] decision will continue to cap the share price," says Robert Uhl of Friedman Billings & Ramsey in a recent research report. Like a majority of analysts, he is neutral on Forest. He doesn't own shares, but his firm says it seeks to do business with companies covered in research reports.
