TheStreet Ratings rates Koppers as a buy. The company's strengths can be seen in multiple areas, such as its solid stock price performance, impressive record of earnings per share growth, compelling growth in net income, revenue growth and notable return on equity. We feel these strengths outweigh the fact that the company has had generally poor debt management on most measures that we evaluated. You can view the full Koppers Ratings Report.
