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, expanding profit margins, solid stock price performance and notable return on equity. We feel these strengths outweigh the fact that the company has had somewhat weak growth in earnings per share. You can view the full Garmin Ratings Report.
