CEO Suresh Vasudevan said, "As we look back on fiscal year 2015 and Q4 of 2015 in particular, we are convinced that we are now reaching an inflection point as enterprises of all sizes and service providers are concluding that the economic benefits of a modern architecture justify the risks of moving away from long-standing incumbent vendor relationships. We see this as the beginning of a secular share shift that presents a massive growth opportunity for us over the next several years."

TheStreet Ratings team rates NIMBLE STORAGE INC as a Sell with a ratings score of D. TheStreet Ratings Team has this to say about their recommendation:

"We rate NIMBLE STORAGE INC (NMBL) a SELL. This is driven by a number of negative factors, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its feeble growth in its earnings per share and deteriorating net income."
