The company's strengths can be seen in multiple areas, such as its robust revenue growth, impressive record of earnings per share growth, largely solid financial position with reasonable debt levels by most measures, good cash flow from operations and notable return on equity. We feel these strengths outweigh the fact that the company has had lackluster performance in the stock itself. You can view the full Ryanair Ratings Report.
