Separately, TheStreet Ratings Team has a "Hold" rating with a score of C- on the stock.

The primary factors that have impacted the rating are mixed. The company's strengths can be seen in multiple areas, such as its robust revenue growth, compelling growth in net income and attractive valuation levels.
