The company has a P/E ratio of 18.5, above the average telecommunications industry P/E ratio of 13.3 and above the S&P 500 P/E ratio of 17.7. TheStreet Ratings rates NeuStar as a buy. The company's strengths can be seen in multiple areas, such as its revenue growth, largely solid financial position with reasonable debt levels by most measures, growth in earnings per share, good cash flow from operations and solid stock price performance. We feel these strengths outweigh the fact that the company has had somewhat disappointing return on equity. You can view the full NeuStar Ratings Report.
