TheStreet Ratings team rates IRON MOUNTAIN INC as a Hold with a ratings score of C. The team has this to say about their recommendation:
"We rate IRON MOUNTAIN INC (IRM) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its revenue growth, expanding profit margins and good cash flow from operations. However, as a counter to these strengths, we also find weaknesses including a generally disappointing performance in the stock itself, generally higher debt management risk and disappointing return on equity."
