TheStreet Ratings rates Neogen 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, impressive record of earnings per share growth, compelling growth in net income and solid stock price performance. We feel these strengths outweigh the fact that the company is trading at a premium valuation based on our review of its current price compared to such things as earnings and book value.
