The company has a P/E ratio of 12.4, equal to the average drugs industry P/E ratio and below the S&P 500 P/E ratio of 17.7. TheStreet Ratings rates Neurocrine as a hold. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and notable return on equity. However, as a counter to these strengths, we find that we feel that the company's cash flow from its operations has been weak overall. You can view the full Neurocrine Ratings Report.
