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, solid stock price performance, impressive record of earnings per share growth and compelling growth in net income. We feel these strengths outweigh the fact that the company shows weak operating cash flow. You can view the full SciClone Ratings Report.
