Myriad Genetics Inc. (MYGN) reported first quarter fiscal 2010 earnings of 31 cents per share, which was below the Zacks Consensus Estimate by a penny. The company had earned 25 cents per share in the year-ago period.

Myriad Genetics spun off its therapeutics business in July 2009 to focus on molecular diagnostics going forward. Although the molecular diagnostics business is performing well, we remain concerned about the slowdown in revenue growth in recent quarters.

The competition confronting Myriad Genetics products in the biotechnology and genetics testing field is also a concern. We have an Underperform rating on the stock.Zacks Investment Research
