TheStreet Ratings rates Siga 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 solid stock price performance. However, as a counter to these strengths, we also find weaknesses including unimpressive growth in net income, weak operating cash flow and feeble growth in the company's earnings per share.
